TY - JOUR T1 - The ecological-evolutionary interplay: density-dependent sexual selection in a migratory songbird AN - 1712562780; PQ0001954450 AB - Little is understood about how environmental heterogeneity influences the spatial dynamics of sexual selection. Within human-dominated systems, habitat modification creates environmental heterogeneity that could influence the adaptive value of individual phenotypes. Here, we used the gray catbird to examine if the ecological conditions experienced in the suburban matrix (SM) and embedded suburban parks (SP) influence reproductive strategies and the strength of sexual selection. Our results show that these habitats varied in a key ecological factor, breeding density. Moreover, this ecological factor was closely tied to reproductive strategies such that local breeding density predicted the probability that a nest would contain extra-pair offspring. Partitioning reproductive variance showed that while within-pair success was more important in both habitats, extra-pair success increased the opportunity for sexual selection by 39% at higher breeding densities. Body size was a strong predictor of relative reproductive success and was under directional selection in both habitats. Importantly, our results show that the strength of sexual selection did not differ among habitats at the landscape scale but rather that fine-scale variation in an ecological factor, breeding density, influenced sexual selection on male phenotypes. Here, we document density-dependent sexual selection in a migratory bird and hypothesize that coarse-scale environmental heterogeneity, in this case generated by anthropogenic habitat modification, changed the fine-scale ecological conditions that drove the spatial dynamics of sexual selection. This article aims to quantify how anthropogenic habitat modifications and the ecological factors associated with these changes affect the dynamics of sexual selection in a migratory bird. The results show that localized breeding density and frequency dependent interactions between the sexes can influence reproductive strategies and the opportunity for and the strength of sexual selection.

The floras range in age from near the Pennsylvanian-Permian boundary into the Lower Permian, occurring in the Community Pit, Robledo Mountains and Apache Dam Formations. The oldest, from the Community Pit Formation (CPF) occur in micritic mudstones preserved in a small, possibly submarine, paleovalley. The flora is dominated by voltzialean conifers (the oldest reported occurrence of this lineage), Dichophyllum moorei, and calamitalean foliage. Several assemblages occur in rocks of the Robledo Mountains Formation (RMF), a partial equivalent of the Lower Permian Abo Formation, which crops out extensively to the north. The most extensive of these RMF floras is dominated almost exclusively by walchian conifers, preserved in interbedded siltstones and claystones with evidence of periodic subaerial exposure. Small collections from other sites are dominated by conifers, and include callipterids and Taeniopteris, or by the gigantopterid seed plant Gigantopteridium, extremely rare in Abo and equivalent rocks, or by Supaia, locally abundant elsewhere in the Abo. A single occurrence of Taeniopteris was recorded in the Apache Dam Formation, in a deposit that appeared to be intermittently flooded and repeatedly re-colonized by plants. The RMF floras are typical for rocks of the Early Permian Abo red beds and occur in facies similar to those found elsewhere in the Abo throughout central and southern New Mexico. The CPF flora, however, is unique compositionally and in terms of the facies in which it is preserved. It appears to be coastal vegetation that includes elements typical of younger (Missourian-Kasimovian) and older (late Leonardian-Kungurian) floras elsewhere in equatorial Pangea.

The trace fossils, other associated fossils and the Hueco sediments provide a remarkable window on the local Early Permian coastal ecosystem. The Hueco section consists of (ascending): (1) the uppermost 45 m of the Shalem Colony Fm., mostly thick-bedded marine limestones with brachiopods and the middle Wolfcampian fusulinid Pseudoschwagerina (2) Community Pit Fm., approximately 140 m of interbedded marine limestone (mostly micrite) and shale with numerous fossilized coniferous logs, evidently driftwood from the nearby land; (3) Robledo Mountains Fm., 125 m of interbedded marine limestone and shale and red bed siliciclastics that yield extensive trace fossil assemblages and fossil foliage; and (4) Apache Dam Fm., at least 25 m of mostly cherty algal limestone. The traces are almost exclusively locomotion traces of arthropods and vertebrates, though some resting traces and shallow subsurface grazing trails are known. Most of the trace fossil assemblages represent the Diplichnites ichnoguild of the Scoyenia ichnofacies, though recent discoveries of localized burrowing and marine-influenced ichnofossil assemblages indicate a complex mosaic of ichnoassemblages. The associated paleoflora is dominated by conifers of several morphotypes, as is typical of Abo paleofloras to the north. The trace-fossil-bearing red beds of the Robledo Mountains Fm. have been interpreted as either tidal flat or fluvial deposits. We interpret them as unchannelized sheetflood deposits on a distal coastal plain. This eliminates the apparent conundra of traces of animals who were not salinity tolerant and the absence of fluvial channels in the red beds. It also supports recognition of an ecosystem alien to the modern world, one in which vast coastal mud and sand flats hosted a coniferous forest flora and a fauna that apparently lacked vertebrate herbivores.

Mapping of young lava flow fields is providing evidence that the basic hydraulic, thermal, and structural events during the emplacement of lava flows is surprisingly complex, yet the events can be unraveled. Our work shows that the distribution of magma partials during the lifetime of an eruption and during the corresponding flow field development may be determined. Mapping of the McCartys lava flow, El Malpais, New Mexico, focused on the time-transgressive thermal and mechanical details of emplacement, preserved in the physical details of its surface and interior, is yielding new information on the sequence of emplacement events in large flow-fields. This mapping is being compared with the results of similar mapping on historic lava flows and actively inflating lava flows in Hawai'i. One of the largest sources of complexity is a result of lava inflation, a platform-sheet flow characteristic of large flows that is strongly influenced by the balance of lava margin strength and lava hydrostatic head. Stress in excess of the critical yield strength necessary for breakouts and advance may be governed largely by regional slope or, on low angle slopes, the timing of excess pressure from local inflation. Both the McCartys and 1859 Hawai'i lava flows are extensive sheeted pahoehoe surfaces with micro-spiny surface textures and deformed "skins" of variable thickness (from millimeters to meters). Central platy pahoehoe-bearing platforms with V-shaped pits and marginal clefts are commonly elevated from one to over 10 meters above surrounding pahoehoe sheet lobes. These sheet lobe surfaces were subjected to differential surface stresses causing immediate plastic and subsequent brittle shear, compressional, and extensional deformation zones defined now by thin platy rubble zones. Based on timing estimated from thickness of deformed pahoehoe crusts, the lavas of these platforms were emplaced and deformed in less than a few hours. Subsequent deformation of the margins, squeeze ups in deep clefts, and marginal tilting and apparent elevation of the platforms occurred as late as several weeks after the sheet lobe.

To gain a better understanding of their exhumation history, we acquired zircon ages, geochemical analyses, and cathodoluminescence (CL) images to search for evidence of micro- to macro-scales of deformation. The combination is a powerful means to decipher their tectonomagmatic history. In situ ion microprobe (super 238) U/ (super 206) Pb zircon ages of the granitoids range from 30.0 + or - 3.9 Ma to 14.7 + or - 2.6 Ma (+ or -1sigma ) and indicate the plutons crystallized over approximately 15 m.y. The dated zircons show CL zoning consistent with igneous crystallization and are only located adjacent to or as inclusions in biotite grains. The youngest ages are dominated by a blue color in CL, whereas a majority of older zircons are yellow. Higher Th/U contents are typically shown by zircons with black or dark green colors in CL. Most of the samples of these granitoids indicate they are magnesian, calc-alkalic and peraluminous granite to granodiorites, but variations exist, likely reflecting heterogeneity caused by magma mixing, partial melting, crustal contamination, and post-emplacement fluid interactions as evidenced by the CL images. CL images show that all samples experienced magma mixing, multiple episodes of brittle deformation, and fluid-mediated alteration. Sources for the generation of Northern Menderes Massif granitoids include simple slab induced upwelling from the subduction of the African plate along the Hellenic arc, adiabatic decompression as the northern edge of Turkey's Anatolide-Tauride block delaminates, and upwelling asthenosphere as the continental lithosphere thins during extension.

A small section of Pliocene cetacean rib collected from the Yorktown Formation within the PCS Phosphate Mine (formerly Lee Creek Mine), Aurora, North Carolina, U.S.A., shows evidence of this kind of trophic interaction. In this case study, we offer a diagnosis of bone traumatic pathology in which three bone-forming lesions on the partial rib are interpreted as the reaction to a bite inflicted by a macro-predator, the first such report from a marine environment. In addition to the three well-defined lesions, a thin layer of woven bone covers much of the remaining cortical bone. The combination of the three bone-forming lesions and the thin layer of woven bone suggest the presence of an inflammatory process almost certainly caused by infection secondary to the trauma. Survival following the traumatic event was probably less than 6 weeks. The Neogene chondrichthyan fauna from this locality preserves several large predators, including Carcharocles megalodon, Carcharodon carcharias, Isurus xiphidon and Parotodus benedeni, which were all capable, at least in terms of their size, of having bitten the cetacean. Although most of the odontocetes known from the Yorktown Formation were too small to have inflicted this wound, some of the physeterids may have been large enough to have caused the lesions on the partial rib. This evidence of predation in Pliocene whale bone raises the possibility of similar lesions being found in whale bone recovered from archaeological sites.

On the basis of its thick cuticles, few adaxial stomata, sunken stomata, and dense trichomes, it has been inferred to be a xeromorphic plant. Here we test that hypothesis by analyzing its facies distribution, especially in relation to coals, at 273 site collections from approximately 45 stratigraphic horizons accessioned in the Smithsonian National Museum of Natural History, Washington, D.C., U.S.A. The collections represent mostly (par)autochthonous assemblages and cover the taxon's complete known temporal range west of the Appalachians in west-central Pangaea. Chi-square analysis of facies-occurrence data indicates that M. scheuchzeri had a strong preference for mineral-enriched wetlands that immediately preceded and followed the development of peat swamps and mires (coals), particularly during the late Middle Pennsylvanian (late Moscovian) times, coincident with a period of reduced polar ice volume. In the Late Pennsylvanian, following an interval of global warming and tropical wetland reorganization, paleoequatorial climate shifted to an overall drier mode. This was accompanied by the disappearance of M. scheuchzeri from Europe and its limitation, west of the Appalachians, to the wettest available habitats on the landscape. Thus, our data falsify the hypothesis that M. scheuchzeri was a conventional xerophyte, but highlight the paradox of a plant with apparent xeromorphic features confined to a wetland habitat. We consider several possible explanations for this association: (1) response to nutrient deficiency, (2) response to substrate salinity (due to growth in coastal mangrove habitats), (3) response to the composition of the Paleozoic atmosphere, (4) return on investment (long leaf lifespan), and (5) phylogenetic constraint reflecting ancestral conditions. Our findings have broader implications for interpreting a wide variety of other Pennsylvanian wetland plants, which similarly show "xermorphic" features.

Although their orbitally paced glacioeustatic origins are widely accepted, their climatic signatures are open to interpretation. In this study, we utilize the GENESIS general circulation model (GCM) coupled to dynamic ice sheet and ecosystem components, to explore the response of low-latitude continental climate and high-latitude ice sheets to orbital and atmospheric pCO (sub 2) forcing. Our results suggest that atmospheric pCO (sub 2) concentration exerts the primary control over low-latitude continental climate and high-latitude glaciation. Our experiments constrain the atmospheric pCO (sub 2) window within which late Paleozoic climate was amenable to orbitally-driven glacial-interglacial fluctuations. The results suggest that both high-latitude ice-sheet accumulation and ablation and low-latitude climate change were paced by the eccentricity of Earth's orbit. Periods of high eccentricity amplified precession-driven changes in insolation and promoted high-latitude ice sheet volume fluctuations as well as increased low-latitude precipitation variability. When eccentricity was low, the amplification of precessionally-driven insolation fluctuations was reduced, which promoted high-latitude continental ice sheet stability and less variable low-latitude precipitation. Based on these modeling results we discuss the implications of eccentricity paced precessional-scale climatic changes on low-latitude Pangaean depositional environments.

We have upgraded existing geologic mapping in central Panama with more than 2000 field stations, over 40 petrographic analyses, and more than 30 new geochronological and thermochronological analyses. This data set suggests that the isthmus was an uninterrupted chain above sea level from late Eocene until at least late Miocene times. The basement complex of central Panama is a folded-faulted, similar to 3-km-thick arc sequence, intruded by granitoid bodies and onlapped by mildly deformed upper Eocene and Oligocene strata. Six U/Pb zircon ages in the granitoids-along with published geochronological data-reveal intense late Paleocene to middle Eocene magmatism (58-39 Ma), a temporary cessation of magmatic activity between 38 and 27 Ma, and renewed magmatism between 25 and 15 Ma in a position similar to 75 km south of the former magmatic axis. Thermochronological analyses in zircon (eight U-Th/He ages), and in apatite crystals (four U-Th/He ages and nine fission-track ages) obtained from a subset of 58-54 Ma granitoid bodies record a concordant Lutetian-age (47-42 Ma) cooling from similar to 200 degree C to similar to 70 degree C in similar to 5 m.y., and cooling below similar to 40 degree C between 12 and 9 Ma. Cooling is linked to exhumation by an angular unconformity that separates the deformed basement complex below from mildly deformed, upper Eocene to Oligocene terrestrial to shallow-marine strata above. Exhumation and erosion of the basement complex are independently confirmed by lower Miocene strata that have a detrital zircon signature that closely follows the central Panama basement complex age distribution. These results greatly restrict the width and depth of the strait separating southern Central America from South America, and challenge the widely accepted notion that the Central American Seaway closed in late Pliocene time, when the ice age began.

The processes generating oxidized arc magmas, however, are poorly constrained, although they appear inherently linked to subduction. Near-surface differentiation processes unique to arc settings might drive oxidation of magmas that originate in equilibrium with a relatively reduced mantle source. Alternatively, arc magmas could record the oxidation conditions of a relatively oxidized mantle source. Here, we present new measurements of olivine-hosted melt inclusions from a single eruption of Agrigan volcano, Marianas, in order to test the influence of differentiation processes vs. source conditions on the Fe (super 3+) /Sigma Fe ratio, a proxy for system oxygen fugacity (fO (sub 2) ). We determined Fe (super 3+) /Sigma Fe ratios in glass inclusions using mu -XANES and couple these data with major elements, dissolved volatiles, and trace elements. After correcting for post-entrapment crystallization, Fe (super 3+) /Sigma Fe ratios in the Agrigan melt inclusions (0.219 to 0.282), and their modeled fO (sub 2) s (Delta QFM +1.0 to +1.8), are uniformly more oxidized than MORB, and preserve a portion of the evolution of this magma from 5.7 to 3.2 wt.% MgO. Fractionation of olivine + or - clinopyroxene + or - plagioclase should increase Fe (super 3+) /Sigma Fe as MgO decreases in the melt, but the data show Fe (super 3+) /Sigma Fe ratios decreasing as MgO decreases below 5 wt.% MgO. The major element trajectories, taken in combination with this strong reduction trend, are inconsistent with crystallization of common ferromagnesian phases found in the bulk Agrigan sample, including magnetite. Rather, decreasing Fe (super 3+) /Sigma Fe ratios correlate with decreasing S concentrations, suggesting that electronic exchanges associated with SO (sub 2) degassing may dominate Fe (super 3+) /Sigma Fe variations in the melt during differentiation. In the case of this magma, the dominant effect of differentiation on magmatic fO (sub 2) is reduction rather than oxidation. Tracing back Agrigan melts with MgO>5 wt.% (i.e., minimally degassed for S) along a modeled olivine fractionation trend to primary melts in equilibrium with Fo (sub 90) olivine reveals melts in equilibrium with the mantle beneath Agrigan at fO (sub 2) s of Delta QFM +1 to +1.6, significantly more oxidized than current constraints for the mantle beneath mid-ocean ridges.

The densimetric and thermal Richardson, Froude, Stokes, and settling numbers match those of natural PDCs as does the ratio of thermal to kinetic energy density. The experimental currents have lower bulk Reynolds numbers than natural PDCs, but the experiments are fully turbulent. Consequently, the experiments are dynamically similar to the dilute portions of some natural currents. In general, currents traverse the floor of the experimental tank, sedimenting particles and turbulently entraining, heating, and thermally expanding air until all particle sediments or the currents become buoyant and lift off to form coignimbrite plumes. When plumes form, currents often undergo local flow reversals. Current runout distance and liftoff position decrease with increasing densimetric Richardson number and thermal energy density. As those parameters increase, total sedimentation decreases such that >50% of initial current mass commonly fractionates into the plumes, in agreement with some observations of recent volcanic eruptions. Sedimentation profiles are best described by an entraining sedimentation model rather than the exponential fit resulting from non-entraining box models. Time series analysis shows that sedimentation is not a constant rate process in the experiments, but rather occurs as series of sedimentation-erosion couplets that propagate across the tank floor tracking current motion and behavior. During buoyant liftoff, sedimentation beneath the rising plumes often becomes less organized. Auto-correlation analysis of time series of particle concentration is used to characterize the turbulent structures of the currents and indicates that currents quickly partition into a slow-moving upper portion and faster, more concentrated, lower portion. Air entrainment occurs within the upper region. Turbulent structures within the lower region track sedimentation-erosion waves and indicate that eddies control deposition. Importantly, both eddies and sedimentation waves track reversals in flow direction that occur following buoyant liftoff. Further, these results suggest that individual laminations within PDC deposits may record passage of single eddies, thus the duration of individual PDCs may be estimated as the product of the number of laminations and the current's turbulent timescale.

While preservation is mostly of Burgess Shale-type, giant anomalocaridids also occur in siliceous concretions. Petrographic and geochemical analyses of these concretions reveal their growth history and the circumstances that led to the fossilization of nonbiomineralized anatomy within them. The large (>1 m) concretions are homogeneous in composition and geochemical characteristics, suggesting rapid, pervasive growth of mineral frameworks during decay of the large animals at, or near, the sediment-water interface. Concretions are comprised of ultrafine-grained (2-20 mu m) authigenic quartz, Fe chlorite, and calcite, a composition unlike other described marine concretions. Abundant pyrite, now represented by oxide pseudomorphs, grew adjacent to the anomalocaridid carcasses, but rarely within the matrix of the concretions. This distribution indicates that sulfate reduction around the carcasses was vigorous within otherwise organic-poor sediments resulting in the establishment of prominent chemical gradients around the giant anomalocaridids that led to early precipitation of mineral overgrowth around nonbiomineralized tissues. Rapid precipitation of intergrown silica and Fe chlorite required an abundant source of silica, iron, and aluminum. These ions were likely derived from dissolution of volcanic ash in the sediments. Limited intergrown calcite (delta (super 13) C avg. -12.2 per mil, n=23) precipitated from bicarbonate that was generated largely by sulfate reduction of organic tissues of the carcasses. Whereas Burgess Shale-type preservation of fossils in the Fezouata biota required suppression of degradation, exceptional preservation of anomalocaridids within the siliceous concretions resulted from extensive microbial decomposition of a large volume of organic tissues. Rapid mineralization was facilitated by localization of microbial activity around the large carcasses and must have required an unusually reactive sediment composition.

Four distinct morphologically simple, enigmatic fossils from the Wheeler Formation were analyzed using Raman spectroscopy, and elemental mapping by electron microbeam techniques. These fossils have been interpreted as dissociated algal fragments, and accordingly, were compared to known algal fossils: Yuknessia simplex (green alga; Spence Shale), Marpolia spissa (cyanobacteria; Burgess Shale), and Margaretia dorus (green alga; Burgess and Wheeler formations). All fossils examined were composed of carbonaceous films, at least in part, but varied with respect to secondary mineral coatings: iron oxides were associated with the surfaces of all three algal species to some degree, and in addition, Margaretia dorus exhibited silicification. Fossils characterized by a thin, wispy, filamentous form (Linear Morphotype 2) display mineralogical and morphological similarities with Marpolia spissa, but lack the characteristic longitudinal striping of this species. Filamentous fossils with a coiled form were the only fossils found to contain chlorite. These fossils are interpreted to be fecal strings. Stubby, linear fossils (Linear Morphotype 1) that commonly have been interpreted as fragmented Yuknessia simplex exhibit neither the mineralogical nor the microtextural features of this algal fossil, making this interpretation unlikely. As with Linear Morphotype 1, fossils of Morania fragmenta lack secondary iron oxides and phyllosilicates. Accordingly, they are interpreted to have been composed of labile material that preserves only under inhospitable conditions such as sustained anoxia.

This model explains the precipitation of authigenic iron sulfide minerals on, and around, decaying carcasses in association with microbial mats, cementing the sediment as a sole veneer and retaining the external morphology of the organism in relief on the upper and lower surface of coarse-grained sandy event beds. Although this model has been substantiated by the discovery of abundant microbially induced sedimentary structures (MISS) and pyrite veneers in close association with Ediacaran fossils, it has not been tested previously by experimental taphonomic studies under controlled laboratory conditions. Arthropod larvae that decayed on top of a cyanobacterial mat demonstrated higher quality preservation of fine-scale anatomy than larvae that decayed in the absence of a mat. Decay experiments involving bacterial mats and organic-rich sands generated a black ring extending radially from the decaying carcasses. When this precipitate was analyzed using XPS and ESEM-EDS it revealed the presence of likely iron sulfides, or at least spatially associated Fe and S, and localized concentrations of common aluminosilicate elements (Al, K, Fe, and Mg), which is a composition that has been documented in association with Ediacaran fossil preservation.

Although these deposits present exceptional views into a diverse, nonbiomineralized to lightly biomineralized biota, this taphonomic regime mostly disappears from the fossil record after the Cambrian, with a few notable exceptions. Numerous detailed taphonomic and chemical studies have provided significant insight into modes of fossil preservation in these deposits, although there is still significant debate regarding the preservational and diagenetic mechanisms that may be involved. Compared to previous electron microscopy-based elemental mapping approaches, which have identified the elemental components of similar fossils, Raman spectroscopy allows a determination of the chemical phases and specific mineralogy at the molecular level, as well as the thermal maturity, of these fossils. This approach therefore provides new types of data, such as hematite phase, that may prove helpful for elucidating some of the mechanisms responsible for the exceptional types of preservation found in these deposits, and potentially helps to resolve the existing taphonomic debates.

Solvent-extracted residues from Miocene Larix, Glyptostrobus, and Pinus, Pliocene Picea, and their associated bulk material, yielded abundant polysaccharide pyrolysis products, such as 2-methylfuran, 2-furaldehyde, and levoglucosan, indicating excellent molecular preservation. Comparison of pyrolysates of individual plant taxa and bulk material from the same deposits revealed the dominance of particular plant taxa in these high latitude floras. Comparison with fossil Lagerstatten from Ellesmere Island (late Paleocene) and Axel Heiberg Island (middle Eocene), both in the Canadian Arctic Archipelago, and Clarkia in Idaho, United States (middle Miocene), demonstrated that the quality of molecular preservation of material from Banks Island is similar to that of Axel Heiberg Island and lies between those of Ellesmere Island and the Clarkia deposit. The ranking of molecular preservation was paralleled by scanning electron microscopy (SEM) observations. Analysis of Larix and Glyptostrobus from different geological ages (Eocene-recent) and locations indicated that age does not correlate with molecular preservation in these fossil Lagerstatten. When relative abundance ratios of vinyl phenol (m/z 91+120), guaiacyl (m/z 109+124), and levoglucosan (m/z 60+73) are used as indicators of the preservation of cutin, lignin, and cellulose, our results suggest that variations in the pyrolysates among several genera reflect different original molecular compositions as well as paleoenvironmental conditions for preservation. The data also illuminate the role of labile biomolecules in the taphonomy of three-dimensionally preserved morphological structures in these Arctic plant fossils.

The oldest, from the late Eocene-early Oligocene Gatuncillo Formation, is dominated by podocnemidid pleurodires. The early Miocene Culebra Formation includes both podocnemidids and trionychids. The early to middle Miocene Cucaracha Formation includes taxa classified in Geoemydidae (including Rhinoclemmys panamaensis n. sp.), Kinosternidae (represented by Staurotypus moschus n. sp.), large testudinids, trionychids, and podocnemidids, and finally, the late Miocene Gatun Formation records cheloniid sea turtles. These fossils include the oldest known representatives of Rhinoclemmys, the oldest record of kinosternids in Central America with a more extensive southern paleodistribution for Staurotypus and staurotypines in general, early occurrences of giant tortoises in the Neotropics, the oldest occurrence of soft-shell turtles in the tropics, the oldest late Eocene-early Oligocene Neotropical occurrences of podocnemidids. The Panamanian fossil turtles represent clades that are primarily endemic to North America, showing their very early arrival into the Neotropics prior to the complete emergence of the Isthmus of Panama, as well as their first contact with Caribbean-South American pleurodires by the early Miocene.

These changes have been associated with reduced density of Ovenbirds (Seiurus aurocapilla) and Hermit Thrushes (Catharus guttatus) in 10-20 ha forest stands, and with reduced Ovenbird nesting success. Whether earthworms reduce songbird populations across a regional extent is unclear. We investigated relationships among Lumbricus, vegetation structure, landscape patterns of forest cover, and density of four ground-nesting songbird species at points scattered across the Chequamegon-Nicolet (Wisconsin) and Chippewa (Minnesota) National Forests, USA. In both national forests, Ovenbird density was significantly lower at invaded points than Lumbricus-free points, but only in sugar maple (Acer saccharum) and sugar maple/basswood (Tilia americana) (hereafter, maple-basswood) woodlands. Density of the Hermit Thrush, Black-and-white Warbler (Mniotilta varia), and Veery (Catharus fuscescens) did not differ in relation to Lumbricus. In maple-basswood forests, Lumbricus biomass was the best predictor of Ovenbird density, with greater biomass associated with reduced density. Vegetation structure and landscape pattern variables received weak support as density predictors. Across all forest types, Ovenbird density was most strongly related to forest cover within 500 and 1,000 m radii. Our results suggest that earthworm invasions may pose a regional threat to Ovenbirds within maple-basswood forests of the U.S. northern Midwest.

The aim of the present study was to examine the role of seed dispersal and resprouting that mediate resilience to large fires and evaluate the economic costs that these ecological functions provide. We used field data from 412 plots of the Spanish National Forest Inventory providing information on pre- and post-fire conditions of Mediterranean Pinus spp. and Quercus spp.-dominated forests. Then, we determined the need for restoration (N sub(Rest)) and estimated the minimum pre-fire densities needed to ensure adequate post-fire cover. Economic valuations were assessed through three different scenarios (Sc) of possible human-management actions aimed at ensuring proper post-fire tree cover: Sc. 1) a pre-fire management scenario evaluating the costs of planting Quercus spp. seedlings in the understory, mimicking the whole dispersal function; Sc. 2) a pre-fire scenario in which enrichment plantations increased the densities of natural oaks; and Sc. 3) a post-fire scenario where the restoration is done through planting pines within the burned area. Approximately 90% of the burned area (371 out of 412 plots) was able to recover after fire supporting the view that Mediterranean forests are resilient to fire. This resilience was primarily mediated by biotic seed dispersal and posterior resprouting of tree species. These ecological functions saved between 626 and 1,326 [Euro/ha compared to the human-management actions. Ensuring key ecological processes within forests increases forest resilience and recovery after fire leading to a generally significant saving of economic resources. In a perspective of increased future impact of disturbances and decrease availability of economic resources for forest management, the implications of the present study can be far reaching and extended to other forest planning exercises.

We present a comprehensive overview of diversity and phylogeny as they have figured into the evolution of the Asteroidea from Paleozoic to the living fauna. Living post-Paleozoic asteroids, the Neoasteroidea, are morphologically separate from those in the Paleozoic. Early Paleozoic asteroid faunas were diverse and displayed morphology that foreshadowed later living taxa. Preservation presents significant difficulties, but fossil occurrence and current accounts suggests a diverse Paleozoic fauna, which underwent extinction around the Permian-Triassic interval was followed by re-diversification of at least one surviving lineage. Ongoing phylogenetic classification debates include the status of the Paxillosida and the Concentricycloidea. Fossil and molecular evidence has been and continues to be part of the ongoing evolution of asteroid phylogenetic research. The modern lineages of asteroids include the Valvatacea, the Forcipulatacea, the Spinlosida, and the Velatida. We present an overview of diversity in these taxa, as well as brief notes on broader significance, ecology, and functional morphology of each. Although much asteroid taxonomy is stable, many new taxa remain to be discovered with many new species currently awaiting description. The Goniasteridae is currently one of the most diverse families within the Asteroidea. New data from molecular phylogenetics and the advent of global biodiversity databases, such as the World Asteroidea Database (http://www.marinespecies.org/Asteroidea/) present important new springboards for understanding the global biodiversity and evolution of asteroids.

Sex allocation theory predicts that increased mortality rates should decrease the optimal size at sex change. Therefore we examined how stress (early starvation and exposure to desiccation) affects the size at sex change in Crepidula cf. marginalis a protandrous marine snail. Our results showed significant effects of early starvation on sex change: animals responded to early starvation by losing male characteristics earlier and at smaller sizes, remaining longer in the transitional phase, and becoming female at larger sizes than animals that were provided adequate food throughout. Desiccation on the other hand, decreased the size at which the female reproductive morphology was attained but no other effects were detected. The results of the desiccation treatment are consistent with theoretical predictions that higher mortality rates should decrease size at sex change. The starvation treatment seems to indicate that animals reduce the allocation to reproduction under extreme stress by entering a non-reproductive transitional stage earlier. Instead of regaining the male phase when conditions improved, they grew and rapidly completed the transition to the female phase.

It is most similar to the Eastern Towhee P. erythrophthalmus but differs in having a heavier bill, more robust hindlimbs, and reduced wing and pectoral girdle, with the sternum in particular being shorter, wider, and with a much smaller carina. At least one early historical account (1610) contains a description of a large bunting-like bird that almost certainly refers to this species, which would have been exterminated by introduced pigs, rats, and cats following human settlement of Bermuda in 1612.

Bacteria are associated with the ectoderm layer in newly released planula larvae, in 4-day-old planulae, and on the newly forming mesenteries surrounding developing septa in juvenile polyps after settlement. Roseobacter clade-associated (RCA) bacteria and Marinobacter sp. are consistently detected in specimens of P. astreoides spanning three early developmental stages, two locations in the Caribbean and 3 years of collection. Multi-response permutation procedures analysis on the TRFLP results do not support significant variation in the bacterial communities associated with P. astreoides larvae across collection location, collection year or developmental stage. The results are the first evidence of vertical transmission (from parent to offspring) of bacteria in corals. The results also show that at least two groups of bacterial taxa, the RCA bacteria and Marinobacter, are consistently associated with juvenile P. astreoides against a complex background of microbial associations, indicating that some components of the microbial community are long-term associates of the corals and may impact host health and survival.

We constructed a highly resolved, well-supported phylogeny for New World Dryopteris and used it to investigate biogeographic patterns and divergence times. Methods: We analyzed relationships among 97 species of Dryopteris, including taxa from all major biogeographic regions, with analyses based on 5699 aligned nucleotides from seven plastid loci. Phylogenetic analyses used maximum parsimony, maximum likelihood, and Bayesian inference. We conducted divergence time analyses using BEAST and biogeographic analyses using maximum parsimony, maximum likelihood, Bayesian, and S-DIVA approaches. We explored the monophyly of subgenera and sections in the most recent generic classification and of geographic groups of taxa using Templeton tests. Key results: The genus Dryopteris arose ca. 42 million years ago (Ma). Most of the Central and South American species form a well-supported clade which arose 32 Ma, but the remaining New World species are the result of multiple, independent dispersal and vicariance events involving Asia, Europe, and Africa over the last 15 Myr. We identified six long-distance dispersal events and three vicariance events in the immediate ancestry of New World species; reconstructions for another four lineages were ambiguous. Conclusions: New World Dryopteris are not monophyletic; vicariance has dominated the history of the North American species, while long-distance dispersal prevails in the Central and South American species, a pattern not previously seen in plants.

The oldest assemblage in the region is Khodzhakul from the Kyzylkum Desert of Uzbekistan(early Cenomanian). The next stage includes assemblages from the lower and upper parts of the Bayn Shire Formation of the eastern Gobi Desert, Mongolia(Cenomanian to Santonian). The Iren Dabasu fauna from Inner Mongolia, China, clusters with the Turonian-Santonian faunas from Middle Asia based on the shared presence of the trionychid turtle Khunnuchelys and is likely Santonian in age. Three Middle Asian assemblages(Bissekty, Yalovach, and Bostobe) are endemic in the presence of two crocodyliform taxa (Kansajsuchus and Tadzhikosuchus) but share another crocodyliform (Shamosuchus) with the Gobi assemblages. The Campanian-Maastrichtian assemblages from the Gobi Desert cluster with coeval North American faunas. The Campanian vertebrate assemblages from the Djadokhta and Barun Goyot formations are highly endemic, reflecting semi-arid paleoenvironments. The assemblage from the Nemegt Formation, which existed under more mesic conditions, is similar in composition to those from other fluvial depositional environments(Bissekty, Iren Dabasu, and North American Judithian and Lancian assemblages). The presence of the crested hadrosaurine Saurolophus supports a Maastrichtian age for the Nemegt assemblage. Three Gobi assemblages (Djadokhta, Barun Goyot, and Nemegt) are grouped together based on the shared presence of the endemic turtle Mongolemys and parvicursorine theropods. The Campanian to Maastrichtian assemblages of Central Asia and North America differ from the older assemblages in Asia in the presence of derived Tyrannosauridae, Pachycephalosauria, and Hadrosauridae. In Middle Asia, continental vertebrate assemblages from this time interval remain largely unknown due to regional marine transgressions.

The oldest deposits of paleo-Lake Zaysan are the Tayzhuzgen Formation,as much as 136 m of red-bed mudstone, siltstone, shale, quartzose sandstone, conglomerate and freshwater limestone. The Tayzhuzgen Formation encompasses strata of the Manrak, Tayzhuzgen, Aulisbulak, Aktobe, Dysumbay and Kiin Kerish svitas of the local stratigraphic nomenclature. Dinosaur eggshell fragments occur in the lower part of the Tayzhuzgen Formation at one locality near the Tayzhuzgen River south of Lake Zaysan. At least two primary kinds of eggshell are present: spheroolithid and elongatoolithid. The dinosaur eggshells indicate a Late Cretaceous(likely Maastrichtian) age for the lowerpart of the Tayzhuzgen Formation. Higher in the formation, late? Paleocene fossil plants are present, so the Cretaceous-Paleogene boundary in the Zaysan basin is within the Tayzhuzgen Formation. The stratigraphic interval between Cretaceous and Paleocene fossil horizons in the Tayzhuzgen Formation is only -50m thick, and this suggests that there may be one or more unconformities within the Tayzhuzgen Formation, or that the middle part of the formation is "condensed? which means that sedimentation rates were very slow across the Cretaceous-Paleogene boundary. There is a substantial unconformity at the top of the Tayzhuzgen Formation, where strata of middle or late Eocene(Arshantan, Irdinmanhan or Egilian land-mammal "ages? age are present at the base of the fossil-mammal-bearing section. The Cretaceous-Paleogene boundary in the Zaysan Basin is located stratigraphically very low in the sedimentary section deposited by paleo-Lake Zaysan, and it is not a complete section of the boundary, but likely one marked by one or more unconformities and/or a condensed section produced by slow sedimentation.

Despite the costs, it worked. Until recently, whether by accident or by design, it has suited the United States for space to be expensive. As long as no other country or regional bloc could rival US expenditure on space, US supremacy was assured by these high costs, which have formed a de facto US strategy for space, even after the Cold War. In this sense, we are still living in the Apollo era of space policy. What should our 'After Apollo' space policy be? Perhaps no US response is needed? Our pride may be hurt, but realism suggests that space really doesn't matter. After all space is a small industry. The entire global space industry, by its own Space Foundation estimates in 2007, and including the GPS chips so common in cell phones, amounted to just two-thirds of Walmart's turnover. On the contrary, US competitiveness is threatened, including in space, and this matters. The US government should respond by playing to the nation's strength and play the same role in space in the 21st century, that it played in the development of the American West in the 19th century: making the frontier safe for capitalism. This is not a Cold War style argument that attempts to scare the United States into a renewed space program based on military fears. Rather, the United States has made a huge investment in space, and now has a clear technological advantage. Adapted from the source document.

The new method of three-dimensional reconstructions of the internal morphology of this taxon results in the subjective synonymization of the Nerthebrochinae in favour of the Sellithyridinae. The geographical distribution of species of Hadrosia in South America and Western Europe is a further argument for a direct pathway between these two regions during Early Cretaceous time.

The major element composition of zincian spinel in metamorphosed massive sulfide deposits has been investigated extensively and is actively used as an indicator of mineralization. However, available data for this mineral in granitic pegmatites, including rare-metal (Li, Be, Ta) pegmatites, worldwide is very limited. Previous studies suggest that the composition of gahnite in granitic pegmatites can provide information about the degree of pegmatite evolution and/or fractionation of the original melt. In this study we have investigated the major element composition of gahnite in rare element class (LCT) pegmatites from the Borborema Pegmatite Province (BPP; Capoeira 2, Alto Mirador, Boqueirao, and Carrascao pegmatites), northeastern Brazil, Maryland (Ben Murphy Pegmatite), Maine (Lord Hill Pegmatite), and North Carolina (Burleson, mica-type). The compositions of gahnite in most pegmatites, expressed in terms of mol % hercynite (Hc), gahnite (Gah), and spinel (Spl) end members, fall in the field of granitic pegmatites and have a range of Hc (sub 0.6-9.2) Gah (sub 89.8-98) Spl (sub 0-4.7) . In contrast, gahnite from Maine has the highest Fe and lowest Zn contents yet reported, and its composition is described as Hc (sub 13-27) Gah (sub 72-87) Spl (sub 0-0.96) . This indicates that gahnite from Maine has the lowest degree of pegmatite fractionation among the studied pegmatites. A plot of mol (Fe+Mg)/Al vs. (Zn+Mn)/Al also evidences the lowest degree of fractionation of this pegmatite, whereas the pegmatites from the BPP show the highest degree of fractionation. Gahnite from North Carolina and Maine are similar in composition to that from the Carrascao and Alto Mirador Pegmatites, respectively. Additional studies, including trace elements, are needed to understand the anomalously high Hc component in the pegmatite from Maine and the relationships among the chemical composition of gahnite, the type of pegmatite, and the presence of rare metal mineralization.

Changes in diversity resulting from physical and environmental factors associated with increasing depth have been documented in a variety of habitats. Using coastal and shallow subtidal habitats of the Outer Banks (North Carolina, USA), this study is aimed at assessing spatial variability in diversity and abundance of benthic marine invertebrates (macrofauna), with respect to relative anthropogenic effects. Preliminary data are based on 75 dredge samples of live benthic marine invertebrates from a variety of coastal habitats. Samples from 28 localities have yielded over 2,800 live individuals representing 135 species from 116 genera, and 8 phyla (Annelida, Arthropoda, Brachiopoda, Bryozoa, Cnidaria, Echinodermata, Mollusca, and Porifera). Quantitative analyses of samples along a depth gradient (13 to 63 m) suggest a surprising stability in alpha diversity across multiple habitats and faunal associations. The limited variability in diversity relative to water depth may be the result of anthropogenic effects which, by affecting primarily nearshore habitats, may have preferentially altered the alpha diversity of shallow-water sites. The sites sampled so far also include a transect parallel to shore, consisting of a series of localities within, and adjacent to, a habitually dredged harbor channel. Diversity within the harbor channel is low and increases away from the channel in both directions. This pattern is consistent with the explanation that human impacts may result in suppressed diversity, although interpretations based on a single transect are tenuous. These preliminary analyses suggest that human impacts may play a significant role in affecting alpha diversity of local benthic marine invertebrate communities in the study area. Further sampling efforts should allow us to assess the validity of these tentative conclusions. Ultimately, these data should serve to facilitate evaluations of whether diversity metrics respond predictably to anthropogenic effects in the region and to determine if marine benthos can serve locally as an effective measure of the relative intensity of human impacts.

This approach is particularly fruitful when data on live communities and death assemblages are collected in concert. Here, we employ systematic quantitative sampling of live and dead marine benthos in coastal North Carolina to evaluate macro-faunal associations along an onshore-offshore gradient in a region variably affected by anthropogenic activities. This preliminary report is based on 75 bulk live samples collected using dredges and grabs at multiple sites, including bays, estuaries, harbors, and the open shelf. A total of over 3000 live specimens representing 130 species have been collected so far. The detrended correspondence analysis of the resulting abundance data indicates that bathymetry is the primary controlling factor, with faunal assemblages changing predictably in terms of their taxonomic composition with depth. This is consistent with paleontological studies that show that water depth tends to control multivariate ordinations of fossil benthic assemblages. In contrast, anthropogenic factors appear to play secondary role in influencing the multivariate ordination of samples. The concurrent examination of anthropogenic and bathymetric factors suggests that benthic marine associations of coastal North Carolina are primarily controlled by bathymetry (as would be expected in many pristine settings). In contrast, anthropogenic effects, while discernible, play only a secondary role in determining taxonomic composition of local communities.

Recent studies have used sexual dimorphism to examine potential instances of species selection because it is a trait that is determined by heritable physical characteristics and occurs solely at the species level. These studies have primarily been conducted on extant bird species, using extinction threat levels as a proxy for extinction rates. The results of such studies have varied; in some instances the data have supported a correlation between dimorphism and extinction. The fossil record offers an opportunity to examine the relationship between sexual dimorphism and extinction in the context of actual extinction rates, as opposed to extinction risk. In this study, we will determine if sexual size dimorphism is correlated with extinction or origination in Late Cretaceous ostracodes from the U.S. Gulf Coastal Plain, and whether the magnitude of dimorphism relates to the rates of extinction and origination in these species. We examined 30 species of ostracodes collected from samples of Late Cretaceous sediment in Alabama and Mississippi. Male ostracodes, because of their very large sperm and bulky copulatory apparatus, tend to be more elongate than females. We quantified this dimorphism by digitizing the outline of adult ostracodes, fitting an ellipse to this outline, and calculating the major and minor ellipse axes as measures of valve length and height. We modeled these data as a mixture of two bivariate normal distributions, one for each sex, and used the Mahalanobis distance between males and females to quantify the magnitude of sexual dimorphism for each species. Preliminary analyses indicate that the magnitudes of dimorphism differ among clades. We also compiled stratigraphic ranges for each species from previously published literature. We compared the magnitude of dimorphism for each clade to its stratigraphic range in the Gulf Coastal Plain in order to determine if a correlation exists between sexual size dimorphism and extinction or origination.

Both gem minerals are found in cavities typically 1 to 10 cm wide and are associated with quartz, feldspars, carbonates and sulfides. Historically, the search for hiddenite and emerald in the Hiddenite area has largely been carried out using non-systematic approaches (e.g., random prospecting of plowed fields, wooded areas and stream beds). Recent studies of emerald- and hiddenite-bearing quartz veins from the North American Emerald Mine and the Adams properties have revealed that the crystal morphology of quartz, calcite, pyrite and rutile (QCPR) may serve as potential exploration guides for the discovery of hidden deposits. Emerald-bearing veins are characterized by: (1) quartz with multiple generations that include fine-grained doubly terminated crystals and very coarse-grained prismatic crystals, (2) calcite with largely rhombohedral habit, often accompanied by Fe-rich carbonates (dolomite and siderite), (3) pyrite crystals dominated by octahedral faces and (4) rutile that varies from single untwinned crystals to highly reticulated aggregates. On the other hand, cavities which host hiddenite generally contain "Tessin"-habit quartz or sceptered amethystine quartz, calcite with bihexagonal prism faces, pyrite with cubic morphology and simple untwined rutile crystals. In addition to distinct differences in the crystal morphology of QCPR, associated carbonate and sulfide mineral assemblages provide additional support for the discrimination of the two gem-bearing quartz vein types.

AN - 1080607709; 2012-083867 AB - Tropical cyclones can cause unstable sediment to flow off-shelf causing deposition of event layers off the Mississippi River delta. Short cores ( approximately 40cm) taken after the Hurricanes Rita, Katrina, and Ivan contained event deposits with foraminiferal assemblages distinct from the non-event sediment that overlies and underlies them. These event layers have low densities of foraminifera and high relative abundances of Textularia earlandi and Ammonia tepida. This research uses longer cores ( approximately 2m) to determine if the foraminiferal signature of hurricanes is preserved over a multi-decadal time-scale (based on Pb-210 age determinations). Four kasten cores (approximately 2m in length) were collected in 2007 at depths of 59m, 75m, 87m, and 473m on a transect between Southwest Pass and the Mississippi Canyon. Each core was sampled in 10-cm increments to find if hurricane units could be revealed by their foraminiferal signatures. The three cores along the Southwest Pass yield assemblages dominated by Epistominella vitrea, which becomes less abundant offshore. The near shore samples show signs of decreasing dissolved oxygen indicated by increasing percentages of E. vitrea and Buliminella morgani. Research thus far has not yielded foraminiferal assemblages comparable to the known assemblages in the event layers caused by Rita or Katrina. Varying densities of foraminifera, however suggest that the sedimentological and foraminiferal signature of tropical cyclones may be present but partially lost, obscured by bioturbation.

However, as these radionuclides are relatively short-lived, their utility for the identification of hurricane events decreases with progressively older deposits. Foraminifera, on the other hand, can be preserved for geologically significant amounts of time. Here we set out to investigate whether foraminiferal assemblages contained within recent, known hurricane deposits differ significantly from those of non-hurricane deposits, and whether these differences might give insight on the provenance of this hurricane-deposited sediment. Cores were collected along the same transect during three different cruises: 2004, 2005, and 2007. The transect runs southwest from Southwest pass ( approximately 30m water depth) to the edge of the Mississippi Canyon ( approximately 70m depth). Cores were selected to enable analysis of spatial and temporal changes in foraminiferal assemblages. The 2004 and 2005 core tops reflect the nature of the seafloor foraminiferal community immediately after a hurricane; relatively rich in textulariids. The 2007 core top samples reflect the community after a few years of relatively quiet hurricane seasons: high-density assemblages dominated by Epistominella vitrea. In addition, a cruise along the same transect was conducted in August, 2011, immediately following a major flooding event of the Mississippi River. Surface samples along the transect contain assemblages very different again from those of 2004/2005 and 2007: nearly all the foraminifera were live (stained) juveniles of Nonionella opima. Each hurricane and non-hurricane unit within each core has been compared pairwise using ANOVA. While hurricane units can be statistically discrete from the pre- and post-hurricane units, the different hurricane units can also be statistically discrete from one another. Cluster analyses of all down core samples show a fair amount of separation between hurricane versus non-hurricane deposits, although units from within the same core tend to be more closely grouped than those from another core.

Subsequently, the National Science Education Standards (NSES) (NRC,1996) were developed to be used to guide K-12 science education. State Frameworks were then revised to include guidance from the NSES; while state standards vary, Illinois Learning Standards for Science do incorporate NSES. Emphasis was on developing citizens who would be able to understand the scientific issues that affect their lives. Classroom methods used to impart this information were to be heavily inquiry-based (NRC, 1996). The National Science Education Standards (1996) actually require students to understand what is "the nature of science," as well as to understand science as a human endeavor. In support of all these goals, we developed and tested a three day workshop on paleontological topics for approximately 15 secondary science teachers (grades 7-12) on Eastern Illinois University's campus in Charleston, IL in June 2011. Eastern Illinois University (EIU) has a reputable teacher education program, from which many of the science teachers employed within surrounding school districts in rural, east-central Illinois have graduated. The workshop was funded through an Education and Outreach Grant from the Paleontological Society. The first day of the workshop consisted of content instruction in the form of mini-lectures, discussions, and hands-on inquiry activities. On the second day of the workshop, we led a trip to the Illinois State Museum which will included a "behind the scenes" tour to better understand the role of paleontological collections in scientific research. The third day, we led the teachers on a field trip to the Charleston Stone Company Quarry and field sites around Illinois and Indiana. We count the workshop as a success, but there are lessons we learned putting this together and would like to share our successes and our lessons with others.

Water quality of the estuary-lagoon complex is becoming affected by nutrients introduced into the system at floating fish cages and by the clear-cutting of large areas of fringing mangrove forest for the creation of land-based fish and shrimp pens. We report here on the distribution of benthic foraminifera in the estuary-lagoon and related environmental variables. These data will form the baseline against which future environmental monitoring will be compared. Four thanatofacies are recognized by cluster analysis of the dead foraminiferal abundance data; their distribution is closely related to variations in salinity and other parameters related to the hydrodynamics of the region. This relation is confirmed by DCA and DCCA analyses. A low salinity estuarine thanatofacies (D1) has a low diversity assemblage dominated by the agglutinated taxa Ammotium directum, Trochammina amnicola, Miliammina fusca and Ammobaculites exiguus. A medium salinity lagoon thanatofacies (D2) has low diversity and is strongly dominated by the agglutinated Ammobaculites exiguus. Ammobaculites exiguus and Ammonia aff. A. aoteana dominate a high diversity, high salinity thanatofacies (D3) in both the estuary and the lagoon. A normal marine salinity thanatofacies (D4), found at an inlet and in the immediately adjacent lagoon, has a high diversity assemblage dominated by the calcareous taxa Amphistegina lessonii and Ammonia aff. A. aoteana. Five biofacies recognized by cluster analysis of live foraminiferal data exhibit similar salinity-related distribution patterns as the thanatofacies.

Unlike predictive modeling, scenarios do not attempt to forecast the precise or probable state of any variable at a given point in the future. Instead, comparisons among a set of contrasting scenarios are used to understand the systemic relationships and dynamics of complex socioecological systems and to define a range of possibilities and uncertainties in quantitative and qualitative terms. We describe five examples of scenario studies affiliated with the US Long Term Ecological Research (LTER) Network and evaluate them in terms of their ability to advance the LTER Network's capacity for conducting science, promoting social and ecological science synthesis, and increasing the saliency of research through sustained outreach activities. We conclude with an argument that scenario studies should be advanced programmatically within large socioecological research programs to encourage prescient thinking in an era of unprecedented global change.

Lethal Attack by a Jaguar Sheds Light on the Costs of Predator Mobbing for Capuchins (Cebus capucinus) AN - 1008842865; 16496557 AB - While some primates attempt to avoid predation by fleeing or hiding, others actually approach, harass, and sometimes attack potential predators, a behavior known as mobbing. Mobbing seems to invite obvious risks, but predators have rarely been observed to injure or kill animals that harass them. The true costs of predator mobbing and the functional significance of this behavior remain poorly understood. Here, we report a fatal attack by a jaguar (Panthera onca) on a mobbing capuchin (Cebus capucinus) that we observed on Barro Colorado Island, Panama. This rare observation illustrates that mobbing predators such as large felids can, indeed, be costly. However, to understand fully the costs of mobbing, the energetic and opportunity costs that primates incur when they harass predators must also be considered.

The species previously has been confused with the spotted soapfish, R. subbifrenatusGill 1861, with which it shares a similar pattern of dark spotting on the body. The new species differs from R. subbifrenatus in having yellow pigment on the pectoral fin and distal portions of the soft dorsal, caudal, and anal fins in life (pale in preservative); a different configuration of dark spots on the head; usually dark spots on the belly and caudal fin; almost always four dorsal-fin spines; and modally 25 total dorsal-fin elements, 15 pectoral-fin rays, and 23 total caudal-fin rays. The lower jaw typically extends further anteriorly beyond the upper jaw in the new species than in R. subbifrenatus, and the caudal peduncle is usually narrower. The new Rypticus typically inhabits deeper waters than R. subbifrenatus, and is commonly found on vertical slopes and walls vs. shallow, flat areas. The new species likely would have continued to go unnoticed without examination of genetic data, as there was little reason to look further at R. subbifrenatus until DNA barcoding revealed two distinct genetic lineages within the species. The value of DNA barcoding data in systematic studies and the need for increased support of taxonomy are highlighted. A neotype for Rypticus subbifrenatus is designated.

However, similar to Simpson's proposal that terrestrial species can 'win sweepstakes routes'-whereby highly improbable dispersal events result in colonization across geographical barriers-marine species may also breach land barriers given enough time. To test this hypothesis, we asked whether intertidal marine snails have crossed Central America to successfully establish in new ocean basins. We used a mitochondrial DNA genetic comparison of sister snails (Cerithideopsis spp.) separated by the rise of the Isthmus. Genetic variation in these snails revealed evidence of at least two successful dispersal events between the Pacific and the Atlantic after the final closure of the Isthmus. A combination of ancestral area analyses and molecular dating techniques indicated that dispersal from the Pacific to the Atlantic occurred about 750 000 years ago and that dispersal in the opposite direction occurred about 72 000 years ago. The geographical distribution of haplotypes and published field evidence further suggest that migratory shorebirds transported the snails across Central America at the Isthmus of Tehuantepec in southern Mexico. Migratory birds could disperse other intertidal invertebrates this way, suggesting the Central American Isthmus may not be as impassable for marine species as previously assumed.

A large portion of naturally-occurring Mn oxides tend to be poorly-crystalline and/or nanocrystalline, with not fully resolved crystal structures. In this study, the crystal structures of their synthetic analogs including acid birnessite (AcidBir), delta -MnO (sub 2) , polymeric MnO (sub 2) (PolyMnO (sub 2) ) and a bacteriogenic Mn oxide (BioMnO (sub x) ), have been revealed using atomic pair distribution function (PDF) analysis. Results unambiguously verify that these Mn oxides are layered materials. The best models that accurately allow simulation of pair distribution functions (PDFs) belong to the monoclinic C12/m1 space group with a disk-like shape. The single MnO (sub 6) layers in the average structures deviate significantly from hexagonal symmetry, in contrast to the results of previous studies based on X-ray diffraction analysis in reciprocal space. Manganese occupancies in MnO (sub 6) layers are estimated to be 0.936, 0.847, 0.930 and 0.935, for AcidBir, BioMnO (sub x) , delta -MnO (sub 2) and PolyMnO (sub 2) , respectively; however, occupancies of interlayer cations and water molecules cannot be accurately determined using the models in this study. The coherent scattering domains (CSDs) of PolyMnO (sub 2) , delta -MnO (sub 2) and BioMnO (sub x) are at the nanometer scale, comprising one to three MnO (sub 6) layers stacked with a high disorder in the crystallographic c-axis direction. Overall, the results of this study advance our understanding of the mineralogy of Mn oxide minerals in the environment.

Achieving such a large transformation calls for major biological reorganization. Thus, the speed at which this occurs has important implications for extensive faunal changes, including adaptive radiations and recovery from mass extinctions. To quantify the pace of large-scale evolution we developed a metric, clade maximum rate, which represents the maximum evolutionary rate of a trait within a clade. We applied this metric to body mass evolution in mammals over the last 70 million years, during which multiple large evolutionary transitions occurred in oceans and on continents and islands. Our computations suggest that it took a minimum of 1.6, 5.1, and 10 million generations for terrestrial mammal mass to increase 100-, and 1,000-, and 5,000-fold, respectively. Values for whales were down to half the length (i.e., 1.1, 3, and 5 million generations), perhaps due to the reduced mechanical constraints of living in an aquatic environment. When differences in generation time are considered, we find an exponential increase in maximum mammal body mass during the 35 million years following the Cretaceous-Paleogene (K-Pg) extinction event.

However, ex situ preservation practices can provide safeguards for coral reef conservation. Specifically, modern advances in cryobiology and genome banking could secure existing species and genetic diversity until genotypes can be introduced into rehabilitated habitats. We assessed the feasibility of recovering viable sperm and embryonic cells post-thaw from two coral species, Acropora palmata and Fungia scutaria that have diffferent evolutionary histories, ecological niches and reproductive strategies. In vitro fertilization (IVF) of conspecific eggs using fresh (control) spermatozoa revealed high levels of fertilization (>90% in A. palmata; >84% in F. scutaria; P>0.05) that were unaffected by tested sperm concentrations. A solution of 10% dimethyl sulfoxide (DMSO) at cooling rates of 20 to 30 degree C/min most successfully cryopreserved both A. palmata and F. scutaria spermatozoa and allowed producing developing larvae in vitro. IVF success under these conditions was 65% in A. palmata and 53% in F. scutaria on particular nights; however, on subsequent nights, the same process resulted in little or no IVF success. Thus, the window for optimal freezing of high quality spermatozoa was short ( similar to 5 h for one night each spawning cycle). Additionally, cryopreserved F. scutaria embryonic cells had similar to 50% post-thaw viability as measured by intact membranes. Thus, despite some differences between species, coral spermatozoa and embryonic cells are viable after low temperature (-196 degree C) storage, preservation and thawing. Based on these results, we have begun systematically banking coral spermatozoa and embryonic cells on a large-scale as a support approach for preserving existing bio- and genetic diversity found in reef systems.

There is increasing evidence that many parasite species may comprise a variety of genetically variable lineages, which differ in host specificity and geographic range. In this study, we (1) explored the extent of diversity in the invasive parasitic barnacle Loxothylacus panopaei (Rhizocephala) infecting mud crabs (2) examined the geographic origin for the invasive lineage and (3) assessed if further southward spread of the parasite may be impeded. Along the US Atlantic coast, L. panopaei infects different hosts in its invaded range (Chesapeake Bay to north of Cape Canaveral) compared to one portion of the native range in Southeast Florida. This difference was reflected in genetic lineages on two independent loci, mitochondrial cytochrome oxidase I and nuclear cytochrome c. Both loci were concordant in that they showed one lineage infecting crabs of the genus Panopeus in the native range and one lineage infecting Eurypanopeus depressus and Rhithropanopeus harrisii hosts in the invaded range and in the Gulf of Mexico, thus indicating Gulf of Mexico populations as the most likely source of introduction into Chesapeake Bay. Interestingly, the nuclear marker resolved an additional lineage of parasites infecting panopeid hosts in the native range. All three parasite lineages were well supported, but a decision about species status must await further analyses. Since its introduction in the 1960s, the invasive L. panopaei lineage has expanded its range southward along the US Atlantic coast, now almost reaching the northern limit of native Panopeus-infecting lineages at Cape Canaveral, Florida. We hypothesized that parasite-free E. depressus in Southeast Florida, living in sympatry with infected panopeid populations, might be resistant to infection by the invasive lineage. Our infection experiments rejected this hypothesis, suggesting that any impediment to further southward range expansion might be expected from temperature regimes of the subtropical zoogeographic region south of Cape Canaveral.

However, little is known about environmental factors that influence the distribution of mycorrhizal fungi. Previous studies using seed packets have been unable to distinguish whether germination patterns resulted from the distribution of appropriate edaphic conditions or the distribution of host fungi, as these cannot be separated using seed packets alone. We used a combination of organic amendments, seed packets and molecular assessment of soil fungi required by three terrestrial orchid species to separate direct and indirect effects of fungi and environmental conditions on both seed germination and subsequent protocorm development. We found that locations with abundant mycorrhizal fungi were most likely to support seed germination and greater growth for all three orchids. Organic amendments affected germination primarily by affecting the abundance of appropriate mycorrhizal fungi. However, fungi associated with the three orchid species were affected differently by the organic amendments and by forest successional stage. The results of this study help contextualize the importance of fungal distribution and abundance to the population dynamics of plants with specific mycorrhizal requirements. Such phenomena may also be important for plants with more general mycorrhizal associations.

We employed a multi-scaled approach to investigate the relative importance of feedstock selection, forb content, patch size, and landscape-scale habitat structure and composition as factors shaping the diversity and abundance of terrestrial arthropod communities and the biomass of functional groups of arthropods associated with the provisioning of ecosystem services. Compared to intensively managed annual corn fields, switchgrass and mixed-grass-forb prairie plantings were associated with a 230% and 324% increase in arthropod family diversity and a 750% and 2,700% increase in arthropod biomass, respectively. Biomass of arthropod pollinators, herbivores, predators, and parasites were similarly the highest in mixed-grass-forb prairie, intermediate in switchgrass plantings, and the lowest in cornfields. Community-wide biomass and that of several functional arthropod groups were positively linked to increasing forest cover and land cover diversity surrounding biomass plantings, while pollinator and detritivore biomass was lower in smaller fields. Results not only suggest that the choice of biomass feedstock will play an important role in shaping within-field arthropod diversity but also indicate an important role for the composition of this surrounding landscape. Collectively, our results suggest that selection of perennially based biomass feedstocks along with careful attention to crop placement have important potential to enhance biodiversity conservation and the provisioning of ecologically and economically important arthropod-mediated ecosystem services in future agricultural landscapes.

The aim of this paper is to integrate the fossil and molecular records of Tropical American cupuladriid bryozoans to elucidate their evolutionary history. Molecules and fossils broadly concur in determining the timing of species divergences, and point to seaway constriction associated with the emergence of the Isthmus of Panama as a driver of speciation. We discover that although cross-Isthmian isolation of taxa was important, strong isolating mechanisms also existed within the southwestern Caribbean (SWC), caused by increasing physical and environmental heterogeneity as inter-oceanic straits constricted in the Late Pliocene. During this time of rapid environmental change and instability, recently diverged species pairs existed in locally separated habitats for around 2 million years, only to co-exist after final closure of the seaway. This pattern is consistent with a model of allopatric speciation caused by local isolating mechanisms followed by secondary contact. Fossils also reveal the trajectories of reproductive life history and morphology during and after species divergences. In the SWC, all extant species started to shift from clonal to aclonal reproduction immediately in response to changing oceanographic conditions. However, it took another million years for colonies to gain skeletal strength, a trait that reduces cloning by fragmentation, suggesting that the appearance of advantageous traits was delayed by 1-2 million years and only arose after the process of allopatric speciation had run its course. Changes in colony shape, height and size also appear to lag 2 million years, but may reflect exploitation of the diverse sedimentary environments created as reefs proliferated at this time.

Despite the important role such activities play in connecting ecology and evolution, less is known of the macroevolutionary impact of such influences, especially their role during major evolutionary transitions. The Ediacaran-Cambrian diversification of Metazoa encompassed the appearance and early diversification of virtually all major clades of marine animals and the establishment of metazoan-dominated ecosystems. Here we assess the role of positive ecological feedbacks using a new compilation of the first occurrences of all metazoan phyla, classes; orders and equivalent stem taxa, as well as data from a previously published compendium on fossils from the early to middle Cambrian of China. The results reveal relatively minor feedback during the Ediacaran, but a substantial increase during the Cambrian, principally through bioturbation and the appearance of a number of structural engineers, including sponges. Chemical modification of the environment through filtering and bioturbation seems to have had the largest impact. Data on taxic diversity is a poor proxy for abundance, or for the actual environmental impact of these activities, however.

S. Virgin Islands; evidence of tectonic tilting and subsidence since MIS 5.5 AN - 1849297328; 2016-104246 AB - Most last interglacial (MIS 5.5) coral reef deposits in the Caribbean are emergent. However, in St. Croix, these are found mainly at depth, underneath Holocene material and confirmed by TIMS U-Th dated corals from eight cores through Holocene reefs. The only emergent MIS 5.5 marine deposit peaks at +1.5 m MSL at the northwestern end of the island. The Late Pleistocene surface decreases at least 9.25 m (based on reef crest elevations) in elevation over 15 km along a 0.62 m/km eastward (alongshore) slope. Neither differential erosion nor a naturally sloping deposit is likely, thus the directional elevation decrease requires the influence of tectonic processes. Platform tilting or differential subsidence increasing in rate to the east probably operated both during and since the last interglacial and created progressively greater accommodation space for increasingly thicker overlying Holocene reefs in an eastward direction. Rates of subsidence since MIS 5.5 increase from west to east, from 0.02 mm/year to 0.1 mm/year, assuming a MIS 5.5 +6-m sea level and +4 m initial reef elevation. St. Croix's association with extensional shelf faulting from the northern part of the Virgin Islands Basin, the Anegada Fault to the east and the Puerto Rico Trench to the north may be significant in terms of identifying mechanisms for, or past events resulting in, directional tilting. Identification of differential elevations of MIS 5.5 reefs adds substantially to the information on Late Quaternary tectonism of the area.

Analyses are based on a total of 1,702 zooxanthellate coral specimens collected from six coral-bearing units ranging in age from the earliest Late Miocene to the Early Pleistocene: (1) Valiente Formation (12-11 Ma), (2) Fish Hole Member of the Old Bank Formation (5.8-5.6 Ma), (3) La Gruta Member of the Isla Colon Formation (2.2-1.4 Ma), (4) Ground Creek Member of the Isla Colon Formation (2.2-1.4 Ma), (5) Mimitimbi Member of the Urraca Formation (1.2-0.8 Ma), and (6) Hill Point Member of the Urraca Formation (1.2-0.8 Ma). Over 100 coral species occur in the six units, with faunal assemblages ranging from less than 10% extant taxa (Valiente Formation) to over 85% extant taxa (Ground Creek Member). The collections provide new temporal constraints on the emergence of modern Caribbean reefs, with the La Gruta Member containing the earliest occurrence of large monospecific stands of the dominant Caribbean reef coral Acropora palmata, and the Urraca Formation containing the last fossil occurrences of 15 regionally extinct taxa. Canonical correspondence analysis of 41 Late Miocene to Recent reef coral assemblages from the Caribbean region suggests changes in community structure coincident with effective oceanic closure of the Central American Seaway ( approximately 3.5 Ma). These changes, including increased Acropora dominance, may have contributed to a protracted period of elevated extinction debt prior to the major peak in regional coral extinctions ( approximately 2-1 Ma).

External factors precluded the ability of most people to overeat or under exert. Socio-cultural obesity came about due to the rareness of obesity and its difficulty to achieve. What is rare becomes valuable and what is difficult to achieve becomes a badge of prestige. The modern human obesity epidemic would appear to represent a third class of obesity: environmental obesity. Much like the captive environments which humans construct for the captive/companion animals in our care, the modern human environment has greatly decreased the challenges of life that would restrict food intake and enforce exertion. And like us, our captive/companion animal populations are also experiencing obesity epidemics. A further concern is that maternal obesity alters maternal signaling to offspring, in utero through the placenta and after birth through breast milk, in ways that perpetuate an enhanced vulnerability to obesity. Molecules such as leptin, produced by adipose tissue and placenta, have significant developmental effects on brain areas associated with feeding behavior. Leptin and other cytokines and growth factors are found in breast milk. These molecules have positive effects on gut maturation; their effects on metabolism and brain development are unclear. Placenta and brain also are hotspots for epigenetic regulation, and epigenetic changes may play significant roles in the later vulnerability to obesity and to the development of a diverse array of diseases, including heart disease, hypertension, and noninsulin-dependent diabetes.

Analyzing published and new calculations, we demonstrate robust relations between the size of the largest object and the slope of the size distribution for sizes 0.1 km and larger. These relations yield clear, testable predictions for TNOs and other icy objects throughout the solar system. Applying our results to existing observations, we show that a broad range of initial disk masses, planetesimal sizes, and fragmentation parameters can explain the data. Adding dynamical constraints on the initial semimajor axis of "hot" Kuiper Belt objects along with probable TNO formation times of 10-700 Myr restricts the viable models to those with a massive disk composed of relatively small (1-10 km) planetesimals.

Based on contemporary extinction theory from conservation biology, we predict that in a climatically induced extinction event, species with small geographic ranges are most likely to suffer extinction. We use two methods to reconstruct Pleistocene range sizes for 194 taxa using data from the FAUNMAP database to conduct analyses in ArcGIS. Furthermore, because this extinction event was size selective, we reconstruct range shifts between the Pleistocene and Holocene for 157 species to assess whether climate change preferentially impacted extant large-bodied species. We find that the extinction event did not preferentially impact taxa with small geographic ranges, and that displacement distances were no different for large- and small-bodied species. These results are not consistent with an extinction induced by climate change but may be concordant with anthropogenic causes. Reprinted by permission of Routledge, Taylor and Francis Ltd.

Synthesis and analysis of Late Quaternary animal extinctions on California's Channel Islands suggest that, despite supporting Native American populations for some 13,000 years, few mammal, bird or other species are known to have gone extinct during the prehistoric human era, and most of these coexisted with humans for several millennia.

The Opening of the basin started in the early Eocene and since that time sedimentation has been almost continuous until the early Pliocene. During most of the Miocene a thick deltaic succession, up to 8000m, was accumulated in western Falcon, punctuated by marine transgressions. Early Miocene deltaic sedimentation is characterized by fluvio-dominated deltas, while sedimentation in the middle and late Miocene represent prograding delta-strand plain complexes with the development of extensive wetlands in the delta plain. The vertebrate fauna of the middle and late Miocene Socorro and Urumaco Formations have been correlated biogeographically with the modern Orinoco River system, and other Neogene Fauna in Colombia and Brasil, which has allowed to interpret the origin of the deltaic successions in the Falcon Basin as the product of the proto-Orinoco Delta system, a large river that drained the South American Craton and the Colombian Andes, running in a south-north direction before the major rise of the Merida Andes in the early Pliocene. An alternative paleogeographic interpretation, indicates that the axis of the proto-Orinoco River was diverted to the northeast at the end of the Oligocene, so that all the Miocene deltaic sequences in the basin were sourced from intrabasinal drainage. Here we present an integrated provenance study including data on petrography, detrital Zircon geochronology and heavy minerals analysis for sandstone in the Miocene succession that suggest a major input from the accreted Cretaceous metamorphic and Paleogene Sedimentary rocks of the Lara Nappes and the adjacent northern most Andean massifs including the Perija and Merida Andes Ranges. This study suggest that the deltaic Miocene deposits of the Falcon Basin are the product of small deltas draining low-relief mountains and the tropical weather may be driving the high input of sediment similar to the tropical deltas of the South East Asia islands.

Many factors influence the net reaction; Hg is methylated in the environment but MeHg is also demethylated. The factors controlling the extent of net Hg methylation in sediments are complex and many studies have found contrasting relationships between Hg methylation and ancillary parameters. We report here speciation modeling that was developed through comparison with observational data, mostly from the Chesapeake Bay and the mid-Atlantic continental shelf, to examine and better understand the biogeochemical factors that control Hg(II) bioavailability to methylating bacteria in sediments. This study supports the idea that Hg(II) partitioning between the solid-phase and pore water is strongly controlled by organic matter content (NOM) and dissolved inorganic sulfide concentration. Association of Hg with sulfide in the presence of NOM alters bioavailability through the formation of dissolved and nanoparticulate phases. We suggest that the fraction that was previously thought to represent dissolved HOHgSH (super 0) actually represents a more complex suite of entities in the filtered fraction of both truly dissolved and nanoparticle Hg-S-NOM entities; other data also support this contention Our modeling incorporates the new information on the formation of nanoparticles in the presence of Hg, reduced S and NOM. Overall, measured MeHg production was related to the concentration of this so-called neutral fraction in the filtered solution, and the presentation will highlight the modeling results in light of our data and those of other recent studies, and suggest directions for future work.

We discovered that An. (Ker.) specimens from Peru, and reared-associated specimens from Ecuador, had unambiguous habitus characters that matched those on the male holotype of An. lepidotus. However, the specimens do not exhibit characters of the female allotype and female paratypes of An. lepidotus, which are actually An. pholidotus. Our specimens are the first correctly associated females of An. lepidotus, which allow us to provide a new morphological interpretation for the adult habitus of this species. This finding is also corroborated by molecular data from a portion of the Cytochrome Oxidase I (COI) gene and ribosomal DNA Internal Transcribed Spacer 2 (rDNA ITS2). The pupal stage of An. lepidotus is described for the first time, and additional larval characters are also noted. Diagnostic morphological characters for the adult, pupal, and larval stages of An. pholidotus are provided to separate the two species. All stages of An. lepidotus are easily separated from other currently known species in subgenus Kerteszia and a new key to the females of An. (Kerteszia) is given. Previously published distribution, bionomics, and medical significance data are corrected and enhanced.

Location North American east and west coasts with a focus on San Francisco Bay (SFB). Methods Species richness and prevalence of trematode parasites were examined in the native and introduced ranges of two gastropod host species, Ilyanassa obsoleta and Littorina saxatilis. We divided the native range into the putative source area for introduction and areas to the north and south; we also sampled the overlapping introduced range in SFB. We dissected 14,781 snails from 103 populations and recorded the prevalence and identity of trematode parasites. We compared trematode species richness and prevalence across the hosts' introduced and native ranges, and evaluated the influence of host availability on observed patterns. Results Relative to the native range, both I. obsoleta and L. saxatilis have escaped (lost) parasites in SFB, and L. saxatilis demonstrated a greater reduction of trematode diversity and infection prevalence than I. obsoleta. This was not due to sampling inequalities between the hosts. Instead, rarefaction curves suggested complete capture of trematode species in native source and SFB subregions, except for L. saxatilis in SFB, where infection was extremely rare. For I. obsoleta, infection prevalence of trematodes using fish definitive hosts was significantly lower in SFB compared to the native range, unlike those using bird hosts. Host availability partly explained the presence of introduced trematodes in SFB. Main conclusions Differential losses of parasite richness and prevalence for the two gastropod host species in their introduced range is probably the result of several mechanistic factors: time since introduction, propagule pressure, vector of introduction, and host availability. Moreover, the recent occurrence of L. saxatilis' invasion and its active introduction vector suggest that its parasite diversity and distribution will probably increase over time. Our study suggests that host invasion history and parasite life history play key roles in the extent and diversity of trematodes transferred to introduced populations. Our results also provide vital information for understanding community-level influences of parasite introductions, as well as for disease ecology in general.

Preliminary evidence suggests that climate change and human movements and commerce may have played a role in recent range expansions of avian pathogens. Since the magnitude of climate change in the coming decades is predicted to exceed climatic changes in the recent past, there is an urgent need to determine the extent to which climate change may drive the spread of disease by avian migrants. In this review, we recommend actions intended to mitigate the impact of emergent pathogens of migratory birds on biodiversity and public health. Increased surveillance that builds upon existing bird banding networks is required to conclusively establish a link between climate and avian pathogens and to prevent pathogens with migratory bird reservoirs from spilling over to humans.

We examine the patterns of recent differentiation and the relative roles of gene flow and selection in genetic and morphological variation in the yellow warbler (Dendroica petechia aureola) from the Galapagos and Cocos Islands. Our analyses suggest aureola diverged from Central American lineages colonizing the Galapagos and Cocos Islands recently, likely less than 300000years ago. Within the Galapagos, patterns of genetic variation in microsatellite and mitochondrial markers suggest early stages of diversification. No intra-island patterns of morphological variation were found, even across steep ecological gradients, suggesting that either (i) high levels of gene flow may be homogenizing the effects of selection, (ii) populations may not have had enough time to accumulate the differences in morphological traits, or (iii) yellow warblers show lower levels of 'evolvability' than some other Galapagos species. By examining genetic data and morphological variation, our results provide new insight into the microevolutionary processes driving the patterns of variation.

Here, we quantify the pattern and timing of shifts in the diversity (richness and evenness) and ecology of local (i.e., sample level) mollusk-dominated assemblages during this critical interval using field-collected and published data sets from the U.S. Gulf Coastal Plain. We test whether the biologic and ecologic patterns observed primarily at the global level during this time are also expressed at the local level, and whether the end-Cretaceous (K/Pg) mass extinction and recovery moderated these trends. To explore whether environment had any effect on these patterns, we examine data from shallow subtidal and offshore settings.

Evidence for driftwood transport includes carbonized wood in the same strata. More than half the ca. 225 erratics were quarried in the largely metamorphic Piedmont province (including a few from the Port Deposit Gneiss, still outcropping on the lower Susquehanna River). The lowest sampled bed (Parker Creek Bone Bed) is assigned to the ca. 15.7-15.5Ma peak warmth of the MMCO, which we attribute in part to CO (sub 2) from the coevally erupted Grande Ronde flood basalts (GRFB), the peak effusiveness episode of the Columbia River Flood Basalts (CRFB) The three sampled beds predate the ca. 13.9Ma Antarctic cryosphere expansion, which may be recorded in the Calvert Cliffs by a unique buried channel.

However, the sediment source is still debated. Basaltic dunes on Earth are promising analogs for providing further insights into the assumed basaltic sand dunes on Mars. In our study we characterize basaltic dunes from the Ka'u Desert in Hawaii using optical microscopes, electron microprobe, and spectral analyses. We compare the spectra of terrestrial and Martian dune sands to determine possible origins of the Martian dark sediments. Our results show that the terrestrial sands consist primarily of medium to coarse sand-sized volcanic glass and rock fragments as well as olivine, pyroxene, and plagioclase minerals. Grain shapes range from angular to subrounded. The sample composition indicates that the material was derived from phreatomagmatic eruptions partially with additional proportions of rock fragments from local lava flows. Grain shape and size indicate the materials were transported by aeolian processes rather than by fluvial processes. Spectral analyses reveal an initial hydration of all terrestrial samples. A spectral mineralogical correlation between the terrestrial and Martian aeolian sands shows a similarity consistent with an origin from volcanic ash and lava.

The info-gap framework allows the decision maker to maximize robustness to failure in the presence of uncertainty, where uncertainty is in the parameters of the model and failure is defined as the model output falling below some minimally acceptable performance threshold. Info-gap theory has found particular application to problems in conservation biology and ecological economics. In this study, we applied info-gap theory to an ecosystem services tradeoff case study in which a decision maker aiming to maximize ecosystem service investment returns must choose between two alternative land uses: native vegetation conservation or the establishment of an exotic timber plantation. The uncertain variables are the carbon price and the water price. With a "no-information" uncertainty model that assumes equal relative uncertainty across both variables, info-gap theory identifies a minimally acceptable reward threshold above which conservation is preferred, but below which plantation establishment is preferred. However, with an uncertainty model that allows the carbon price to be substantially more uncertain than the water price, conservation of native vegetation becomes an economically more robust investment option than establishing alien pine plantations. We explored the sensitivity of the results to the use of alternative uncertainty models, including asymmetric uncertainty in individual variables. We emphasize the general finding that the results of info-gap analyses can be sensitive to the choice of uncertainty model and that, therefore, future applications to ecological problems should be careful to incorporate all available qualitative and quantitative information relating to uncertainties or should at least justify the no-information uncertainty model.

We present a quantitative 2400 yr rainfall reconstruction for the Basin of Mexico, from a precisely dated and highly resolved speleothem, that documents highly variable rainfall over the past 2400 yr. Dry conditions peaked during a 150-yr-long late Classic (ca. 600-900 CE) (Common Era) megadrought that culminated at 770 CE which followed centuries of climatic drying that spanned the fall of the city of Teotihuacan ca. 550 CE. The wettest conditions in the 1450s CE were associated with flooding in the Basin of Mexico. Our data suggest that rainfall variability was likely forced by the El Nino-Southern Oscillation, and impacts on spring-fed irrigation agriculture may have been a stressor on Mesoamerican civilizations.

implications for morphological evolution among fossil invertebrates AN - 1832613240; 698307-6 AB - Rate distributions are important considerations when testing hypotheses about morphological evolution or phylogeny. They also have implications about general processes underlying character evolution. Molecular systematists often assume that rates are Poisson processes with gamma distributions. However, morphological change is the product of multiple probabilistic processes and should theoretically be affected by hierarchical integration of characters. Both factors predict lognormal rate distributions. Here, a simple inverse modelling approach assesses the best single-rate, gamma and lognormal models given observed character compatibility for 115 invertebrate groups. Tests reject the single-rate model for nearly all cases. Moreover, the lognormal outperforms the gamma for character change rates and (especially) state derivation rates. The latter in particular is consistent with integration affecting morphological character evolution.

From this ancestral state, dim-light foraging in bees requires significant adaptations to a new photic environment. We used DNA sequences to evaluate the phylogenetic history of the most diverse clade of Apoidea that is adapted to dim-light environments (Augochlorini: Megalopta, Megaloptidia and Megommation). The most speciose lineage, Megalopta, is distal to the remaining dim-light genera, and its closest diurnal relative (Xenochlora) is recovered as a lineage that has secondarily reverted to diurnal foraging. Tests for adaptive protein evolution indicate that long-wavelength opsin shows strong evidence of stabilizing selection, with no more than five codons (2%) under positive selection, depending on analytical procedure. In the branch leading to Megalopta, the amino acid of the single positively selected codon is conserved among ancestral Halictidae examined, and is homologous to codons known to influence molecular structure at the chromophore-binding pocket. Theoretically, such mutations can shift photopigment lambda max sensitivity and enable visual transduction in alternate photic environments. Results are discussed in light of the available evidence on photopigment structure, morphological specialization and biogeographic distributions over geological time.

Numerical simulations of this process, while reproducing many properties of the Belt, fail to generate the high inclinations and eccentricities observed for some objects while maintaining the observed dynamically "cold" population. We present the first of a three-part parameter study of how different dynamical histories of Neptune sculpt the planetesimal disk. Here we identify which dynamical histories allow an in situ planetesimal disk to remain dynamically cold, becoming today's cold Kuiper Belt population. We find that if Neptune undergoes a period of elevated eccentricity and/or inclination, it secularly excites the eccentricities and inclinations of the planetesimal disk. We demonstrate that there are several well-defined regimes for this secular excitation, depending on the relative timescales of Neptune's migration, the damping of Neptune's orbital inclination and/or eccentricity, and the secular evolution of the planetesimals. We model this secular excitation analytically in each regime, allowing for a thorough exploration of parameter space. Neptune's eccentricity and inclination can remain high for a limited amount of time without disrupting the cold classical belt. In the regime of slow damping and slow migration, if Neptune is located (for example) at 20 AU, then its eccentricity must stay below 0.18 and its inclination below 6 degrees .

Currently, however, information regarding the mobility of the HSE in subduction zone environments is limited. To better understand the systematics of highly siderophile elements in subduction settings, we measured Os isotopic compositions and HSE abundances of cores and rinds of meter-scale blocks of eclogite, blueschist and garnet amphibolite from subduction-related melanges within 1) the Franciscan Complex, CA, and a related terrane in Oregon; 2) the Catalina Schist, CA; and 3) the Samana Metamorphic Complex, Samana Peninsula, Dominican Republic. Rinds composed of amphibole, chlorite, + or - phengite, talc, titanite and rutile partly enclose blocks at each location. Mineralogic, petrologic and geochemical data suggest that these rinds are metasomatic features that formed by fluid-mediated interaction between mafic blocks and an ultramafic matrix. The cores of high-grade blocks are characterized by high (Pt+Pd)/(Os+Ir+Ru), and variably radiogenic Os; initial (super 187) Os/ (super 188) Os ranges from 0.197 to 4.30. These characteristics are consistent with the HSE compositions of subducted basalts. In contrast, (Pt+Pd)/(Os+Ir+Ru) of rinds are generally much lower than cores, approaching values typical of mantle peridotites. The initial (super 187) Os/ (super 188) Os of most rinds are also typical of upper mantle peridotites; values for most rinds fall between 0.125 and 0.14. The similarities of the (super 187) Os/ (super 188) Os and HSE abundances between rinds and mantle peridotites indicate that the HSE contained within rinds reflect a contribution by mantle peridotite, whether by fluid-mediated transfer or through mechanical processes. If the HSE signatures of the rinds were generated by fluid-mediated metasomatic processes, these data require remarkably efficient and uniform transference of mantle HSE from peridotitic melange matrix to the exteriors of melange blocks during rind formation. More likely, the rinds are coatings of materials that contain HSE derived from peridotite precursors. These results suggest that centimeter-scale mass transfer by physical mechanisms may be important for some elements within the subduction channel. Abstract Copyright (2012) Elsevier, B.V.

In 1976 an incomplete egg clutch including in ovo embryos of this dinosaur, the oldest known example in the fossil record, was collected from a road-cut talus, but its exact provenance was uncertain. An excavation program at the site started in 2006 has yielded multiple in situ egg clutches, documenting the oldest known dinosaurian nesting site, predating other similar sites by more than 100 million years. The presence of numerous clutches of eggs, some of which contain embryonic remains, in at least four distinct horizons within a small area, provides the earliest known evidence of complex reproductive behavior including site fidelity and colonial nesting in a terrestrial vertebrate. Thus, fossil and sedimentological evidence from this nesting site provides empirical data on reproductive strategies in early dinosaurs. A temporally calibrated optimization of dinosaurian reproductive biology not only demonstrates the primary significance of the Massospondylus nesting site, but also provides additional insights into the initial stages of the evolutionary history of dinosaurs, including evidence that deposition of eggs in a tightly organized single layer in a nest evolved independently from brooding.

However, their fossil record shows evidence of multispecies communities throughout most of the past approximately 26 million years, in different oceanic basins. Morphological differences among co-occurring sirenian taxa suggest that resource partitioning played a role in structuring these communities. We examined body size and ecomorphological differences (e.g., rostral deflection and tusk morphology) among sirenian assemblages from the late Oligocene of Florida, early Miocene of India and early Pliocene of Mexico; each with three species of the family Dugongidae. Although overlapping in several ecomorphological traits, each assemblage showed at least one dominant trait in which coexisting species differed. Fossil sirenian occurrences occasionally are monotypic, but the assemblages analyzed herein show iterative evolution of multispecies communities, a phenomenon unparalleled in extant sirenian ecology. As primary consumers of seagrasses, these communities likely had a strong impact on past seagrass ecology and diversity, although the sparse fossil record of seagrasses limits direct comparisons. Nonetheless, our results provide robust support for previous suggestions that some sirenians in these extinct assemblages served as keystone species, controlling the dominance of climax seagrass species, permitting more taxonomically diverse seagrass beds (and sirenian communities) than many of those observed today.

In this study, we present a maximum likelihood-based biostratigraphic method that demonstrates how microfossil abundance can be used in the stratigraphic placement of isolated samples. Precise correlation and dating of isolated paleontological samples is not possible with current methods, which are primarily intended for the alignment of longer stratigraphic sequences. In contrast, the probabilistic approach provided by likelihood analysis results in sample age estimates with defined confidence intervals. Therefore, all the uncertainties inherent in our age assessment (resulting from small sample sizes, incomplete sampling, imperfect knowledge of stratigraphic distributions, lack of taxonomic resolution of biostratigraphic data, and underlying environmental, paleogeographic, and sedimentologic processes) are explicit in our results. We conclude with a field test of the method, from data collected from an oil well from the Catatumbo Basin, Colombia, illustrating the use of our approach in a real-world case study and highlighting how our method could be generalized to a wide range of stratigraphic problems.

AN - 954643833; 16387745 AB - Herpetologists often complain that, despite amphibians' being one of the most threatened vertebrate classes, there is a dearth of funding and capacity to tackle the global crisis afflicting them. We compared the average funding per species listed under the US Endangered Species Act (ESA) to quantify funding favoritism across vertebrate classes in the United States and compared ESA listings with NatureServe evaluations of endangerment in order to examine listing bias. We found that, on average, listed US amphibians receive one-quarter of the ESA funding that other vertebrate classes do. This inequality is compounded by listing bias, with 82% of the amphibians found to be at risk by NatureServe remaining unlisted under the ESA. We recommend that federal, state, and private conservation groups take reactive andproactive measures to build capacity to sustain this important class of vertebrates for future generations.

We used mitochondrial DNA sequencing to characterize the diversity of 2 genera of vector-mediated parasites (Plasmodium and Haemoproteus) in avian blood samples from the western Indian Ocean region and explored their relationship with parasites from continental Africa. We detected infections in 68 out of 150 (45 3%) individuals and cytochrome b sequences identified 9 genetically distinct lineages of Plasmodium spp. and 7 lineages of Haemoproteus spp. We found considerable heterogeneity in parasite lineage composition across islands, although limited sampling may, in part, be responsible for perceived differences. Two lineages of Plasmodium spp. and 2 lineages of Haemoproteus spp. were shared by hosts in the Indian Ocean and also on mainland Africa, suggesting that these lineages may have arrived relatively recently. Polyphyly of island parasites indicated that these parasites were unlikely to constitute an endemic radiation and instead probably represent multiple colonization events. This study represents the first molecular survey of vector-mediated parasites in the western Indian Ocean, and has uncovered a diversity of parasites. Full understanding of parasite community composition and possible threats to endemic avian hosts will require comprehensive surveys across the avifauna of this region.

Although the observed granulation pattern is well reproduced by the three-dimensional (3D) models, oversimplification of radiative relaxation leads to the prediction of temperature fluctuations that are too high (by a factor of 10 to 100) and result in a monotonic decrease with height in the chromosphere of the horizontally and temporally averaged temperature, and hence in the prediction of absorption lines at wavelengths where only emission lines are observed on the Sun. New values of solar abundances of oxygen and other metals are based on 3D hydrodynamic models with temporal and spatial fluctuations that are far greater than those observed. These new abundances destroy the previous agreement of observed modes with acoustic eigenmodes that had been predicted for the old abundances from a solar model for which the sound speed throughout most of the Sun was determined to an accuracy of a few parts in 10 super(4). One expects that, when radiative relaxation is properly accounted for, 3D models will reproduce the essential characteristics of the solar atmosphere, among them a positive temperature gradient in the outward direction and hence exclusively emission lines in the extreme ultraviolet at all times and positions in the nonmagnetic chromosphere. A minimum characteristic length of 0.1 arcsec is identified for the solar atmosphere, below which there is no significant structure in the actual Sun, only in wave models of the Sun. This criticism does not detract from the notable success of hydrodynamic modeling to explain the mechanism by which chromospheric H sub(2V) and K sub(2V) bright points are formed.

Habitat filtering is expected to select for similar traits among coexisting species that share similar habitat conditions, whereas competitive exclusion is expected to limit the ecological similarity of coexisting species leading to trait differentiation. Here, we explore how functional traits vary among 19 understory palm species that differ in their distribution across a gradient of soil resource availability in lower montane forest in western Panama. We found evidence that habitat filtering influences species distribution patterns and shifts community-wide and intraspecific trait values. Differences in trait values among sites were more strongly related to soil nutrient availability than to variation in light or rainfall. Soil nutrient availability explained a significant amount of variation in site mean trait values for 4 of 15 functional traits. Site mean values of leaf nitrogen and phosphorus increased 37 and 64%, respectively, leaf carbon:nitrogen decreased 38%, and specific leaf area increased 29% with increasing soil nutrient availability. For Geonoma cuneata, the only species occurring at all sites, leaf phosphorus increased 34% and nitrogen:phosphorus decreased 42% with increasing soil nutrients. In addition to among-site variation, most morphological and leaf nutrient traits differed among coexisting species within sites, suggesting these traits may be important for niche differentiation. Hence, a combination of habitat filtering due to turnover in species composition and intraspecific variation along a soil nutrient gradient and site-specific niche differentiation among co-occurring species influences understory palm community structure in this lower montane forest.

Recently, bird bills have been demonstrated to be important convective and radiant heat sinks. Larger bills have greater surface area than smaller bills and could serve as more effective thermoregulatory organs under hot conditions. The heat radiating function of bills should be more important in open habitats with little shade and stronger convective winds. Furthermore, as a means of dumping heat without increasing water loss through evaporation, bills might play a particularly important thermoregulatory role in heat loss in windy habitat where fresh water is limited. North American salt marshes provide a latitudinal gradient of relatively homogeneous habitat that is windy, open, and fresh-water limited. To examine the potential role of thermoregulation in determining bill size variation among ten species or subspecies of tidal marsh sparrows, we plotted bill size against maximum summer and minimum winter temperatures. Bill surface areas increases with summer temperature, which explained 82-89% of the variance (depending upon sex) when we controlled for genus membership. Latitude alone predicted bill surface area much more poorly than summer temperature, and winter temperatures explained < 10% of the variance in winter bill size. Tidal marsh sparrow bill morphology may, to a large degree, reflect the role of the bill in expelling excess body heat in these unbuffered, fresh-water-limited environments. This new example of Allen's rule reaffirms the importance of physiological constraints on the evolution of vertebrate morphologies, even in bird bills, which have conventionally been considered as products of adaptation to foraging niche.

Flexible models, such as generalized additive models (GAMs), can address data issues, and machine learning techniques (e.g. gradient boosting) can help resolve modelling issues. Gradient boosted GAMs do both. Here, we illustrate the advantages of this technique using data on benthic macroinvertebrates and fish from 1573 small streams in Maryland, USA. 2.We assembled a predictor matrix of 15 watershed attributes (e.g. ecoregion and land use), 15 stream attributes (e.g. width and habitat quality) and location (latitude and longitude). We built boosted and conventionally estimated GAMs for macroinvertebrate richness and for the relative abundances of macroinvertebrates in the Orders Ephemeroptera, Plecoptera and Trichoptera (%EPT); individuals that cling to substrate (%Clingers); and individuals in the collector/gatherer functional feeding group (%Collectors). For fish, models were constructed for taxonomic richness, benthic species richness, biomass and the relative abundance of tolerant individuals (%Tolerant Fish). 3.For several of the responses, boosted GAMs had lower pseudo R super(2)s than conventional GAMs for in-sample data but larger pseudo R super(2)s for out-of-bootstrap data, suggesting boosted GAMs do not overfit the data and have higher prediction accuracy than conventional GAMs. The models explained most variation in fish richness (pseudo R super(2)=0.97), least variation in %Clingers (pseudo R super(2)=0.28) and intermediate amounts of variation in the other responses (pseudo R super(2)s between 0.41 and 0.60). Many relationships of macroinvertebrate responses to anthropogenic measures and natural watershed attributes were nonlinear. Fish responses were related to system size and local habitat quality. 4.For impervious surface, models predicted below model-average macroinvertebrate richness at levels above c.3.0%, lower %EPT above c.1.5%, and lower %Clingers for levels above c.2.0%. Impervious surface did not affect %Collectors or any fish response. Prediction functions for %EPT and fish richness increased linearly with log sub(10) (watershed area), %Tolerant Fish decreased with log sub(10) (watershed area), and benthic fish richness and biomass both increased nonlinearly with log sub(10) (watershed area). 5.Gradient boosting optimizes the predictive accuracy of GAMs while preserving the structure of conventional GAMs, so that predictor-response relationships are more interpretable than with other machine learning methods. Boosting also avoids overfitting the data (by shrinking effect estimates towards zero and by performing variable selection), thus avoiding spurious predictor effects and interpretations. Thus, in many ecological settings, it may be reasonable to use boosting instead of conventional GAMs. JF - Methods in Ecology and Evolution AU - Maloney, Kelly O AU - Schmid, Matthias AU - Weller, Donald E AD - Smithsonian Environmental Research Center, 647 Contees Wharf Road, PO Box 28, Edgewater, MD 21037-0028, USA.

The characteristics of the host star are well constrained by high-resolution spectroscopy combined with an asteroseismic analysis of the Kepler photometry, leading to an estimated mass and radius of 0.970 + or - 0.060 M [] and 0.979 + or - 0.020 R []. The depth of 492 + or - 10 ppm for the three observed transits yields a radius of 2.38 + or - 0.13 Re for the planet. The system passes a battery of tests for false positives, including reconnaissance spectroscopy, high-resolution imaging, and centroid motion. A full BLENDER analysis provides further validation of the planet interpretation by showing that contamination of the target by an eclipsing system would rarely mimic the observed shape of the transits. The final validation of the planet is provided by 16 radial velocities (RVs) obtained with the High Resolution Echelle Spectrometer on Keck I over a one-year span. Although the velocities do not lead to a reliable orbit and mass determination, they are able to constrain the mass to a 3sigma upper limit of 124 M, safely in the regime of planetary masses, thus earning the designation Kepler-22b. The radiative equilibrium temperature is 262 K for a planet in Kepler-22b's orbit. Although there is no evidence that Kepler-22b is a rocky planet, it is the first confirmed planet with a measured radius to orbit in the habitable zone of any star other than the Sun.

N1 - Last updated - 2017-01-24 N1 - CODEN - #07653 ER - TY - JOUR T1 - A predation risk-and-avoidance model of nestling responses to parental vocalizations AN - 1171886083; 17344087 AB - Question: How does the nest type of a bird species - cup versus cavity - affect the evolution of its nestlings' responses to parental vocalizations? Background: Nestling birds show distinct behavioural responses either to parental begging-solicitation calls (switch-on begging, lower-frequency sounds) or to parental alarm calls (switch-off begging, high-frequency sounds), but rarely to both. Previous theory suggested that differences in the vibrational conductance of cup versus cavity nests drive the evolution of divergent nestling responses to the different types of parental vocalizations. Many predators eavesdrop on begging displays of nestling birds, then locate the nest and prey on the brood. The risk of predation on broods in cup nests is consistently greater than on broods in cavity nests. New theory: Whether nestlings respond to parental begging-solicitation calls (switch-on) or to parental alarm calls (switch-off) is dependent on a trade-off influenced by predation risks. Although switch-on calls are more efficient at protecting the nestlings that perceive them, they are less efficient at delivering their signal to younger nestlings with poorer sensory and discriminatory abilities (compared with switch-off calls). Thus, where predation risk is high, 'off' calls are favoured; where predation risk is lower, 'on' calls are favoured. Hypotheses: Cup-nesting species, which have higher rates of predation, use 'off' signals, which their young are able to sense early in life before they can sense 'on' signals. Cavity-nesting species are the opposite in all particulars. In addition, cavity nestlings develop the ability to sense low-frequency 'on' sounds later than cup nestlings develop the ability to sense high-frequency 'off' signals. Method: We examined existing comparative data on predation rates at different nesting locations. Using auditory brainstem response studies, we also examined data on the development (ontogeny) of acoustic sensitivity in altricial avian species. Results: Nestlings of cup-nesting species suffer relatively higher predation rates than nestlings of cavity-nesting species. At first, nestlings can hear only a narrow range of sound frequencies. Nestlings gradually develop sensitivity to the full spectrum of vocalizations only after several weeks. The sparse data available on avian auditory ontogeny indicate that cup-nesting species develop early sensitivity to high-frequency sounds, and cavity nesters do so to lower-frequency sounds. Conclusion: The higher predation rates of cup nesters compared with cavity nesters, coupled with the post-hatching delay of all nestlings in achieving full sensitivity to the different types and frequency ranges of parental calls, provide a reasonable explanation for the evolutionary advantage of alarm calls to cup nesters and begging-solicitation calls to cavity nesters.

These impacts have ramifications for animals that share resources and across trophic levels. High deer densities result from an absence of predators or high plant productivity, often due to human habitat modifications, and from the desires of stakeholders that set deer management goals based on cultural, rather than biological, carrying capacity. Success at maintaining forest ecosystems require regulating deer below biological carrying capacity, as measured by ecological impacts. Control methods limit reproduction through modifications in habitat productivity or increase mortality through increasing predators or hunting. Hunting is the primary deer management tool and relies on active participation of citizens. Hunters are capable of reducing deer densities but struggle with creating densities sufficiently low to ensure the persistence of rare species. Alternative management models may be necessary to achieve densities sufficiently below biological carrying capacity. Regardless of the population control adopted, success should be measured by ecological benchmarks and not solely by cultural acceptance.

These schists represent fragments from the actual slab-mantle interface at nearly equal 27 km depth. Their heterogeneous lithology with a metasomatic character indicates significant mobility of major elements in the Mariana forearc, a region of melange formation as it can also be observed in onland exposures such as the Catalina Schist. As the Mariana forearc blueschists show no late stage alteration they permit the direct study of material transfer during the subduction processes at an active convergent margin. This study presents the first data of detailed B isotope (delta (super 11) B) and light element variations in blueschist-facies minerals from the Mariana arc system. The primary foci are B and Li concentrations and delta (super 11) B values analyzed by SIMS and ToF-SIMS techniques. Minerals such as (Na-rich) amphibole, phengite and chlorite are found to be strongly enriched in Li (up to 70 mu g/g), Be (up to 8 mu g/g) and B (up to 35 mu g/g) and with delta (super 11) B values of -6 + or - 4 ppm. These new data are consistent with isotopically heavy B being released into the Mariana forearc mantle wedge (serpentinization of dry mantle peridotite after interaction with B-rich slab-released high pH fluids) and confirm models of significant B-loss and B isotope fractionation during forearc (shallow) slab dehydration. The elevated Li, Be and B concentrations in minerals that comprise the bulk of the rocks, namely, amphibole, phengite, and chlorite bear a strong potential to further transport Li and B as well as the isotopically light component of B to greater depths in the mantle, where ongoing metamorphism is responsible for further isotope and elemental fractionation and the formation of distinct mantle reservoirs, e.g. volcanic arc and oceanic intra-plate (OIB) magmas.

Previous research has shown that many mammals became smaller during the Paleocene-Eocene Thermal Maximum (PETM), but the timing and magnitude of that change relative to climate change have been unclear. A high-resolution record of continental climate and equid body size change shows a directional size decrease of approximately 30% over the first approximately 130,000 years of the PETM, followed by a approximately 76% increase in the recovery phase of the PETM. These size changes are negatively correlated with temperature inferred from oxygen isotopes in mammal teeth and were probably driven by shifts in temperature and possibly high atmospheric CO (sub 2) concentrations. These findings could be important for understanding mammalian evolutionary responses to future global warming.

Unambiguous skeletal correlates of postcranial pneumaticity first appeared in the Late Triassic (approximately 210 million years ago), when they evolved independently in several groups of bird-line archosaurs (ornithodirans). These include the theropod dinosaurs (of which birds are extant representatives), the pterosaurs, and sauropodomorph dinosaurs. Postulated functions of skeletal pneumatisation include weight reduction in large-bodied or flying taxa, and density reduction resulting in energetic savings during foraging and locomotion. However, the influence of these hypotheses on the early evolution of pneumaticity has not been studied in detail previously. We review recent work on the significance of pneumaticity for understanding the biology of extinct ornithodirans, and present detailed new data on the proportion of the skeleton that was pneumatised in 131 non-avian theropods and Archaeopteryx. This includes all taxa known from significant postcranial remains. Pneumaticity of the cervical and anterior dorsal vertebrae occurred early in theropod evolution. This 'common pattern' was conserved on the line leading to birds, and is likely present in Archaeopteryx. Increases in skeletal pneumaticity occurred independently in as many as 12 lineages, highlighting a remarkably high number of parallel acquisitions of a bird-like feature among non-avian theropods. Using a quantitative comparative framework, we show that evolutionary increases in skeletal pneumaticity are significantly concentrated in lineages with large body size, suggesting that mass reduction in response to gravitational constraints at large body sizes influenced the early evolution of pneumaticity. However, the body size threshold for extensive pneumatisation is lower in theropod lineages more closely related to birds (maniraptorans). Thus, relaxation of the relationship between body size and pneumatisation preceded the origin of birds and cannot be explained as an adaptation for flight. We hypothesise that skeletal density modulation in small, non-volant, maniraptorans resulted in energetic savings as part of a multi-system response to increased metabolic demands. Acquisition of extensive postcranial pneumaticity in small-bodied maniraptorans may indicate avian-like high-performance endothermy.

We also measured three physical variables at each site: paleotopographic level, grain size, and total organic content. Paleoenvironmental conditions and paleofloral composition at Big Cedar Ridge covary strongly and are highly heterogeneous on small spatial scales. The reconstructed vegetation has some similarities with extant topogenous fens, but also important differences. Non-monocot angiosperms were abundant only on wet, mineral substrates that had been disturbed shortly before preservation, consistent with the weedy life histories that are inferred for their Early Cretaceous ancestors. Many non-monocot angiosperms grew in small, dispersed populations, consistent with the hypothesis that they were biotically pollinated. Overall, non-monocot angiosperm abundance was low compared with many modern wetlands. A single species of coryphoid palm was the dominant on moist, stable, moderately organic-rich sites, a pattern seen in some subtropical to tropical wetlands in the present day. Fern thickets at Big Cedar Ridge occupied highly organic, possibly low-nutrient substrates, and were dominated by Dipteridaceae, Gleicheniaceae, Schizaeaceae, and Matoniaceae. The overall high diversity and abundance of pteridophytes is unusual in the context of modern vegetation, regardless of climate zone, and probably represents a late occurrence of pteridophyte-dominated vegetation that was common earlier in the Mesozoic. Plant distributions at Big Cedar Ridge combine aspects of pre-angiosperm and modern vegetation in a way that suggests both niche conservatism and niche evolution on geological time scales.

Our study, however, finds stratigraphic and (super 14) C evidence that the tephra instead results from numerous eruptions throughout a 300-year period between about 1500 and 1800. The stratigraphic evidence includes: (1) as many as six pure lithic ash beds interleaved in sand dunes made of earlier Keanakako'i vitric ash, (2) three lava flows from Kilauea and Mauna Loa interbedded with the tephra, (3) buried syneruptive cultural structures, (4) numerous intraformational water-cut gullies, and (5) abundant organic layers rich in charcoal within the tephra section. Interpretation of 97 new accelerator mass spectrometry (AMS) (super 14) C ages and 4 previous conventional ages suggests that explosive eruptions began in 1470-1510 CE, and that explosive activity continued episodically until the early 1800s, probably with two periods of quiescence lasting several decades. Kilauea's caldera, rather than forming in 1790, predates the first eruption of the Keanakako'i and collapsed in 1470-1510, immediately following, and perhaps causing, the end of the 60-year-long, 4-6 km (super 3) 'Aila'au eruption from the east side of Kilauea's summit area. The caldera was several hundred meters deep when the Keanakako'i began erupting, consistent with oral tradition, and probably had a volume of 4-6 km (super 3) . The caldera formed by collapse, but no eruption of lava coincided with its formation. A large volume of magma may have quickly drained from the summit reservoir and intruded into the east rift zone, perhaps in response to a major south-flank slip event, leading to summit collapse. Alternatively, magma may have slowly drained from the reservoir during the prolonged 'Aila'au eruption, causing episodic collapses before the final, largest downdrop took place. Two prolonged periods of episodic explosive eruptions are known at Kilauea, the Keanakako'i and the Uwekahuna Tephra (Fiske et al., 2009), and both occurred when a deep caldera existed, probably with a floor at or below the water table, and external water could readily interact with the magmatic system. The next period of intense explosive activity will probably have to await the drastic deepening of the present caldera (or Halema'uma'u Crater) or the formation of a new caldera.

The quasicrystal grains are intergrown with diopside, forsterite, stishovite, and additional metallic phases [khatyrkite (CuAl (sub 2) ), cupa- lite (CuAl), and beta -phase (AlCuFe)]. This assemblage, in turn, is en- closed in a white rind consisting of diopside, hedenbergite, spinel (MgAl (sub 2) O (sub 4) ), nepheline, and forsterite. Particularly notable is a grain of stishovite (from the interior), a tetragonal polymorph of silica that only occurs at ultrahigh pressures (> or = 10 Gpa), that contains an inclusion of quasicrystal. An extraterrestrial origin is inferred from secondary ion mass spectrometry (super 18) O/ (super 16) O and (super 17) O/ (super 16) O measurements of the pyroxene and olivine intergrown with the metal that show them to have isotopic compositions unlike any terrestrial minerals and instead overlap those of anhydrous phases in carbonaceous chondrite meteorites. The spinel from the white rind has an isotopic composition suggesting that it was part of a calcium- aluminum-rich inclusion similar to those found in CV3 chondrites. The mechanism that produced this exotic assemblage is not yet understood. The assemblage (metallic copper-aluminum alloy) is extremely reduced, and the close association of aluminum (high temperature refractory lithophile) with copper (low temperature chalcophile) is unexpected. Nevertheless, our evidence indicates that quasicrystals can form naturally under astrophysical conditions and remain stable over cosmic timescales, giving unique insights on their existence in nature and stability.

preliminary results AN - 1510396766; 2014-020739 AB - We have combined the NEOWISE and Sloan Digital Sky Survey data to study the albedos of 24,353 asteroids with candidate taxonomic classifications derived using Sloan photometry. We find a wide range of moderate to high albedos for candidate S-type asteroids that are analogous to the S complex defined by previous spectrophotometrically based taxonomic systems. The candidate C-type asteroids, while generally very dark, have a tail of higher albedos that overlaps the S types. The albedo distribution for asteroids with a photometrically derived Q classification is extremely similar to those of the S types. Asteroids with similar colors to (4) Vesta have higher albedos than the S types, and most have orbital elements similar to known Vesta family members. Finally, we show that the relative reflectance at 3.4 and 4.6 mu m is higher for D-type asteroids and suggest that their red visible and near-infrared spectral slope extends out to these wavelengths. Understanding the relationship between size, albedo, and taxonomic classification is complicated by the fact that the objects with classifications were selected from the visible/near-infrared Sloan Moving Object Catalog, which is biased against fainter asteroids, including those with lower albedos.

This study used various spectroscopic methods and time-of-fight (ToF-) SIMS to characterize and analyze for boron in natural type IIb blue diamonds, including the well-known Hope and the Blue Heart diamonds, and on one high-pressure, high-temperature annealed natural stone. Infrared spectroscopy measurements reveal uncompensated boron values as large as 1.72 + or - 0.15 ppm, which is significantly higher than the previously reported maximum of 0.5 ppm. ToF-SIMS analyses gave spot total boron concentrations as high as 8.4 + or - 1.1 ppm for the Hope diamond to less than 0.08 ppm in other blue diamonds. By comparison, a type Ia diamond did not show detectable boron. ToF-SIMS analyses revealed strong zoning of boron in some diamonds, which was confirmed by mapping the uncompensated boron using synchrotron infrared spectroscopy. This greater range of boron concentrations compared to previous studies might be explained by the larger number of natural diamonds analyzed here, 78, compared to <10 samples reported in the literature. The samples in this study are all gem-quality diamonds, including some Intense to Fancy-Deep blue diamonds; color intensity, however, only loosely correlates with the boron content. Boron is also likely responsible for the phosphorescence emissions of type IIb diamonds, in the red at 660 nm and in the blue-green at 500 nm. Our results are consistent with previous work suggesting that the emissions are caused by donor-acceptor pair recombination processes involving boron and other defects. The exact nature of the phosphorescence processes is still not fully understood, but likely involves complex steps of charge carrier trapping and detrapping.

A test on the endangered Florida panther AN - 926891162; 16370201 AB - Genetic introgression has been suggested as a management tool for mitigating detrimental effects of inbreeding depression, but the role of introgression in species conservation has been controversial, partly because population-level impacts of genetic introgressions are not well understood. Concerns about potential inbreeding depression in the endangered Florida panther (Puma concolor coryi) led to the release of eight female Texas pumas (P. c. stanleyana) into the Florida panther population in 1995. We used long-term reproductive data (1995-2008) collected from 61 female Florida panthers to estimate and model reproduction probability (probability of producing a litter) and litter size, and to investigate the influence of intentional genetic introgression on these parameters. Overall, 6-month probability of reproduction ( plus or minus 1SE) was 0.232 plus or minus 0.021 and average litter size was 2.60 plus or minus 0.09. Although F sub(1) admixed females had a lower reproduction probability than females with other ancestries, this was most likely because kittens born to F sub(1) females survive better; consequently, these females are unavailable for breeding until kittens are independent. There was no evidence for the effect of ancestry on litter size or of heterozygosity on probability of reproduction or litter size. In contrast, earlier studies have shown that genetic introgression positively affected Florida panther survival. Our results, along with those of earlier studies, clearly suggest that genetic introgression can have differential effects on components of fitness and highlight the importance of examining multiple demographic parameters when evaluating the effects of management actions.

We evaluated the relative importance of above- versus below-ground competition during the first years of old-field succession on soil with low fertility in Southern Mexico, using the premise that competition for light is size-asymmetric, unlike competition for nutrients. Plant growth is thus expected to be disproportionally impeded by larger neighbors. We studied how growth and survival of 3.5-5.5 m tall saplings of Cecropia peltata and Trichospermum mexicanum, two pioneer species that dominate the secondary forests in the study region, varied with the abundance and size of neighboring trees in 1-2 year old secondary vegetation. We found that local neighborhood basal area varied 10-fold (3 to 30 cm super(2) m super(-2)) and explained most of the variation in diameter and height growth of the target saplings. Most growth variables were strongly affected by the neighbors bigger than the focal trees with no significant additive effect of the smaller neighbors, indicating asymmetric competition. Smaller neighbors did have a small but significant additive effect on the diameter growth of Cecropia saplings and stem slenderness of Trichospermum saplings.

The transformative paper on ballast water provided a baseline of patterns, processes and predictions of marine introductions, underpinned a dramatic increase in research on the topic, and presented a foundational insight for an international approach to vector management. The 25 year anniversary of JT Carlton's 'Transoceanic and interoceanic dispersal of coastal marine organisms: the biology of ballast water' coincides with an International Maritime Organization (IMO) convention for management of ballast water that has not been fully ratified. The emergence of ship biofouling as a vector of management concern worldwide has also prompted renewed efforts to reduce species transfers by ships through new policy initiatives.

In order to determine the geographical origin of the genus and its history of speciation events, we constructed phylogenies based on cytochrome oxidase I and sperm bindin from all its species. Both the mitochondrial and the nuclear gene genealogies show that Arbacia originated in the temperate zone of the Southern Hemisphere and gave rise to three species in the eastern Pacific, which were then isolated from the Atlantic by the Isthmus of Panama. The mid-Atlantic barrier separated two additional species. The bindin data suggest that selection against hybridization is not important in the evolution of this molecule in this genus. Metz et al. in a previous publication found no evidence of selection on bindin of Arbacia and suggested that this might be due to allopatry between species, which obviated the need for species recognition. This suggestion formed the basis of the conclusion, widely spread in the literature, that the source of selection on sea urchin bindin (where it does occur) was reinforcement. However, the range of Arbacia spatuligera overlaps with that of two other species of Arbacia, and our data show that it is hybridizing with one of them. We found that even in the species that overlap geographically, there are no deviations from selective neutrality in the evolution of bindin.

In the pan-tropical shrub genus Piper, this tendency is thought to be higher in shade-tolerant than light-demanding species, and to represent a trade-off with annual seed production. Here we use molecular markers to identify clones in five Piper species varying in light requirements. We test predictions that (i) asexual recruitment success is highest in shade-tolerant species, and (ii) that consequently, shade-tolerant species are characterized by lower genotypic diversity than light-demanding Piper. We found that two shade-tolerant Piper species recruited asexually more frequently (36-42% of sampled shoots were of asexual origin) than, two light-demanding and one shade-tolerant species (0-26%). Furthermore, as predicted, genotypic diversity was negatively correlated with the frequency of asexual recruitment in the population. Nonetheless, genotypic diversity of Piper was high compared with other clonal plants. The proportion of unique genotypes found per population ranged from 0.58 to 1.0 and the genotypic Simpson's diversity ranged from 0.93 to 1.0 for all five species. Our results suggest that even though asexual reproduction plays an important role in maintaining local populations of Piper in the understory, it does not seem to reduce genotypic diversity to levels that will threaten these species ability to respond to environmental change.

To survive and reproduce in these areas, birds must transmit their signals to intended receivers. As an arena for acoustic communication, 2 salient features of the urban environment are an abundance of reflective surfaces and a high level of low-frequency anthropogenic noise. Each presents unique communication challenges, with hard surfaces reflecting and distorting high frequencies and noise masking low-frequency song components. Based on this, we predicted that noise level would affect minimum song frequency and urban development (percentage of impervious surface) would affect maximum frequency and frequency range. We compared the effects of urban development and noise on songs of 6 bird species at 28 sites along an urban to rural gradient, across a broad range of noise levels. We found that minimum song frequency increased as noise level increased for 2 of 6 species, with 5 of 6 species showing a strong trend in the predicted direction. Species with lower frequency songs were more affected by noise. Maximum frequency and frequency range decreased for 2 of 6 species as urban development increased, and this effect was stronger for species with higher frequency songs. For some species, minimum frequency only increased with noise at less urban sites and similarly, maximum frequency and frequency range only decreased with urbanization at quiet sites, suggesting a trade-off between different vocal adjustments. Ours is the first study to investigate how noise and urban development affect song frequency characteristics of multiple bird species.

Alternatively, it has also been hypothesized that closely related invaders might be more successful than novel invaders because they are pre-adapted to conditions in their new range; a paradox coined Darwin's Naturalization Conundrum. To date, these hypotheses have been tested primarily at the regional scale, not within local plant communities where introduced species colonize, compete and encounter herbivores. Location Global. Methods and Results We used community phylogenetics to analyse data from 49 published experiments to examine the importance of phylogenetic relatedness and generalist herbivory on native and exotic plant success at the community level. Plants that were categorized as 'invasive' were indeed less related to the recipient community than 'non-pest' exotic plants. Distantly related exotic plants were also more abundant than closely related species. Phylogenetic relatedness predicted herbivore impact, but in a way that was opposite to predictions, as herbivores had stronger, not lesser, impacts on distantly related plants. Importantly, these same patterns generally held for native plants, as distantly related native plants were more abundant and more susceptible to herbivores than closely related species, ultimately resulting in herbivores suppressing community-level phylogenetic diversity. Main conclusions Distantly related plants were more locally successful despite experiencing stronger control by generalist herbivores, a finding that was robust across native and exotic species. To our knowledge, this is the first evidence that phylogenetic matching influences the local success of both native and exotic species and that herbivores can influence community phylodiversity. Phylogenetic relatedness explained a relatively small portion of the variance in the data even after taking herbivory into account, however, suggesting that phylogenetic matching works in combination with other factors to influence community assembly.

The latest Aptian assemblage is dominated by few long-ranging Hedbergella and large-sized Paraticinella that completely disappear near the base of the Niveau Kilian organic-rich level. Planktic foraminiferal assemblages from across the Niveau Kilian to the top of the studied section are composed of minute, but very distinctive smooth-surfaced species of Microhedbergella miniglobularis and Mi. renilaevis. The appearance of Mi. renilaevis in the middle part of the Niveau Kilian represents a major step in the evolution and diversification of the Albian planktic fauna. The lowest occurrence of this taxon is recorded immediately above the extinction level of the Aptian hedbergellids and corresponds with a dramatic decrease in the number of planktic and benthic foraminifera specimens, with a 1 ppm negative delta (super 13) C excursion in bulk carbonate, and evidence for regional rise in sea-surface temperature. Our careful study of the species composition permits refinement of the previous biozonation by using the appearance datum of Mi. renilaevis as a zonal boundary event. Changes include redefinition of the top of the Microhedbergella miniglobularis Zone and designation of a new Microhedbergella renilaevis Zone. The same sequence of events was reported from several deep-sea sites in the Atlantic and Indian Oceans. Therefore, documentation of the planktic foraminiferal turnover, combined with the carbon-isotope stratigraphy in the Col de Pre-Guittard section, provide new criteria for defining the Global Boundary Stratotype Section and Point for the base of the Albian Stage in a stratigraphically complete succession.

This may have detrimental effects for calcifying species of plankton, shellfish and corals, particularly in high-latitude cold-water regions, where ocean acidification is predicted to occur within the next few decades. The encrusting coralline alga Clathromorphum nereostratum is endemic to subarctic regions of the North Pacific where it forms extensive calcium carbonate deposits on the shallow seafloor, forming reef-like habitats for complex invertebrate communities. Coralline algae form annual growth increments within their high-Mg calcite skeleton and have been shown to be well suited for multi-centennial oceanographic reconstructions of past climatic changes in mid-to-high latitude regions where past oceanographic observations are sparse. By combining measurements of skeletal density with widths of annual growth increments, calcification rates (which are influenced by factors such as temperature and pH) were obtained. Our study examined annual calcification records compiled from a number of coralline algal specimens obtained from the Aleutian archipelago. The calcification rates display interannual cycles that covary with the Pacific Decadal Oscillation (PDO). This may indicate that natural cycles in ocean-atmosphere dynamics drive factors such as ocean pH thus modulating the influence of ocean acidification on coralline calcification rates.

However, microbialites - the dominant reef components of the Proterozoic - were still abundant in most archaeocyathan reefs. Although such reefs were a locus for carbonate production, it is unclear how much carbonate was produced skeletally. This analysis of well-known early Cambrian archaeocyathan patch reefs of the Forteau Formation, southern Labrador, demonstrates that skeletal carbonate was abundantly produced in these archaeocyathan reefs, although only about half was produced by archaeocyathans. Trilobites, echinoderms and brachiopods contributed substantially to the total carbonate budget, particularly in grainstone facies flanking the reefs. Through point count analysis of samples collected from the reef core and flanking grainstones, it can be demonstrated that skeletal material was most abundant in grainstone facies, where animals such as trilobites and echinoderms contributed significantly to carbonate production. In contrast, microbial fabrics were more abundant than skeletal fabrics in the reef core, although archaeocyathan material was more abundant than other skeletal debris. Similar to modern reefs, these reefs created a variety of habitats that allowed for the proliferation of skeletal organisms living on and around the reef, thereby promoting skeletal carbonate production through ecosystem engineering.

N1 - Date revised - 2014-01-01 N1 - Last updated - 2014-07-17 ER - TY - JOUR T1 - A structure refinement for monoclinic hydrohematite AN - 1535203196; 2014-037860 AB - In ferruginous soils, nano- to micro-scale hematite (alpha -Fe (sub 2) O (sub 3) ) plays a central role in redox processes and contaminant cycling. Hematite is known to incorporate structural OH (super -) and water, and the requisite charge balance is achieved by iron vacancies. Prior researchers have suggested that the defective hematite structures form unique phases called "protohematite" (PH) and "hydrohematite" (HH). These phases are distinguished from stoichiometric hematite (SH) by their degree of hydration and iron deficiency. Furthermore, past infrared and Raman spectroscopic studies have assigned a lower-symmetry space group to PH/HH (R3c) relative to that of SH (R-3c). However, the existence and structure of these phases has been contentious, largely due to the lack of in situ X-ray diffraction data. Here we present a new structure refinement for HH in a monoclinic space group (I2/a) using time-resolved X-ray diffraction (TR-XRD) data collected at the Advanced Photon Source (APS). Starting with ferric chloride solutions, we collected TR-XRD data during the in situ hydrothermal precipitation of akaganeite and its transformation to HH. Sealed quartz capillaries (1.0 mm diameter) were heated at 200 degrees C while XRD data were collected every 25-30 seconds. Rietveld refinements suggested a new monoclinic HH structure. In our experiments, distinct peak splitting was observed in the hematite diffraction patterns, indicating a violation of the 3-fold rotational symmetry. The observed peak splitting in our data was outside the range calculated for sample displacement, and furthermore video footage obtained during the reaction showed particles uniformly convecting throughout the volume of the capillary. We therefore refined the structure in the various subgroups of R-3c. As the fit using I2/a was statistically no worse than that in lower symmetry groups, we selected this space group for our refinement. A monoclinic unit cell with parameters of a = 13.7493(15) Aa, b = 5.0121(4) Aa, c = 5.4418(6) Aa, beta = 147.6250(17) degrees provided a good fit and significant reduction in X 2 and Rwp relative to S.G. R-3c. Our results demonstrate that the in situ formation of the defective hematite phase, HH, was successfully captured. Moreover, HH is structurally distinct from SH and may form as a lower-symmetry monoclinic phase in soils.

Stratigraphically ordered events relative to the base of the Niveau Kilian include: (1) abrupt extinction of nearly all late Aptian planktic foraminifer species between -3.0 and -2.3 m; (2) appearance of the small planktic foraminifer Microhedbergella miniglobularis at -2.0 m; (3) onset of a 1 ppm negative delta (super 13) C excursion at -1 m; (4) minimum delta (super 13) C values between +0.3 and +0.6 m; and (5) appearance of the small planktic foraminifer Microhedbergella renilaevis at +0.4 m. Reports of this same sequence of planktic foraminifer and carbon isotope events from deep-sea sites in the southern South Atlantic, North Atlantic, and Indian Oceans demonstrate that they can be globally correlated. Other bioevents at the Pre-Guittard section that can be used for regional and global correlation include the evolutionary transition from subcircular to circular forms of the calcareous nannofossil Praediscosphaera columnata between -31 m and +35 m, the first occurrence of the calcareous nannofossil Helicolithus trabeculatus at -6.5 m, and the first occurrence of the ammonite zonal biomarker Leymeriella tardefurcata at +31 m. We propose that the GSSP for the base of the Albian Stage be defined at the lowest occurrence of Mi. renilaevis where delta (super 13) C values are at their minimum.

The K-bentonites are isochrons; the sandstones and the disconformities beneath them are not. Our ability to parse out differences in the timing of prograding sands and gravels across the proximal Blount foredeep is significant for sequence stratigraphic models. At the over 40 exposures studied, a subtle to pronounced disconformity occurs beneath the sandstone or conglomerate. Stratigraphic relations show unequivocally that (1) the Walker Mountain Sandstone at 29 sections in southwestern Virginia, and the "middle sandstone member" at 6 sections in northeastern Tennessee, are older than the K-bentonites; (2) the Colvin Mountain Sandstone at 7 sections in Alabama and Georgia is contemporaneous with the K-bentonites; and (3) the unnamed conglomerates and pebbly sandstones at 2 sections near Dalton, Georgia are younger than the K-bentonites. The diachroneity of these gravels and coarse sands likely resulted from changes in the fluvial networks draining the Taconic highlands, with pulses of gravel and coarse sand being delivered episodically into the basin over several million years and at different depositional loci, as a result of tectonic, rather than eustatic, activity. Petrographic, sedimentologic, and cathodoluminescent analyses show that these sediments share a similar provenance, accumulated in similar depositional settings, and had similar diagenetic histories. If the K-bentonites were not present, these coarse clastics would be correlated with each other from Alabama to Virginia, and the disconformity beneath them would likely be given regional or even global sequence stratigraphic significance. The unconformity beneath the Walker Mountain Sandstone in Virginia has already been given such significance, being labeled as the "M3-M4" sequence boundary; nonetheless, other prominent disconformities occur beneath other coarse clastics in the Blount molasse that are younger (Georgia and Alabama) or older (Tennessee) than the Walker Mountain. This shows that in active margin settings not every unconformity is of glacioeustatic origin, or has a eustatic component, especially in settings where tectonic activity governs and dominates the depositional system, as with the Taconic foredeep.

Although oil exploration in the area generally targets reservoirs associated with Cenozoic clastic sequences, ongoing exploration focuses on Cretaceous non-traditional reservoirs. Recent new targets are located in cross-stratified sandstones in the upper Maastricthian Umir Formation, a unit generally considered to be a highly effective regional seal. Structural complexities and the presence of a large regional unconformity obscure the regional distribution of the oil-bearing sandstones and the exploratory risks are high. The depositional environment for the Umir formation is interpreted as a bay or extensive coastal plain where terrestrial (pollen and spores) and marine palynomorphs (dinoflagellate cysts and acritarchs) are abundant; hence palynology is the best biostratigraphic proxy to be used. Here we present the organic-walled microfossil biozonation that we are developing for the Maastrichtian Umir Formation. The study area is located in Central Eastern MMVB, on the western side of the Los Andes syncline. Ninety-nine samples from four cores covering a stratigraphic thickness of 2990 feet are being analyzed for palynological content. The samples were prepared in the Colombian Petroleum Institute, and standard palynological analyses are being conducted at Louisiana State University. Thus far, the palynological assemblage is characterized by the occurrence of key Maastrichtian markers from Northern South America such as Echimonocolpites protofranciscoi, Proteacidites dehaani, Buttinia andreevi, Echitriporites trianguliformis, Crusafontites grandiosus, Bacumorphomonocolpites tausae, Syndemicolpites typicus, Tetradites umirensis, Ulmoideipites krempii and Monocolpites grandispiniger. A predominant coastal plain environment is suggested by the abundance of several species of Echimonocolpites, Gemmamonocolpites, Monocolpites, Psilamonocolpites and Spinizonocolpites genera, and a constant and abundant record of Psilatriletes group. Spikes in abundance of dinocysts and foram linings evidence six marine-influenced events. The excellent recovery of palynomorphs shows potential to find new events for Maastrichtian biostratigraphy of Northern South America. Major biostratigraphic events will be used to improve geological models, reduce the exploratory risk and will serve as a key tool for on-site biostratigraphic control of exploratory wells.

AN - 1434026696; 18513367 AB - All societies are characterized by the capacity of their members to distinguish one another from outsiders. Ants are among the species that form "anonymous societies": members are not required to tell each other apart as individuals for the group to remain unified. Rather, each society depends on shared cues recognized by all its members. These cues permit societies to reach populations in the low millions in certain ant and termite species, and to grow indefinitely populous, expansive, and possibly long lasting in a few other ant species, which are described as having supercolonies. Anonymous societies are contrasted with "individual recognition societies" such as those of most vertebrates, which are limited to a few individuals by the necessity that the members individually recognize each other. The shared recognition cues of ants provide clear criteria for defining colonies and are what enables a supercolony to remain a single society no matter how large it becomes. I examine the often conflicting ideas about the best studied ant with supercolonies, the Argentine ant (Linepithema humile). Its invasive supercolonies, containing in some cases billions of workers and queens spread over hundreds of square kilometers, can be most parsimoniously understood as single colonies that have had an opportunity to expand across regions of suitable habitat because of a lack of well-matched competitors. This capacity for unrestricted growth is the defining characteristic of supercolonies. There is no evidence that the local patchiness of nests and patterns of worker and food traffic within these wide-ranging populations are so invariant that supercolonies do not exist but instead are collections of numerous independent nest clusters that should be called "colonies." Nor is there evidence for the hypothesis that invasive supercolonies have been able to grow large and successful overseas only as a result of evolving through genetic drift or selection to become fundamentally different from the smaller colonies typical of the species' region of origin around northern Argentina. The most unique feature of the Argentine ant, however, is not that its colonies are anonymous or that they can grow indefinitely large-though the last trait is found only in a few ant species and humans. Rather, it is that Argentine ant colonies do not interbreed. Indeed, the only fighting among Argentine ants occurs along colony borders, which even reproductives seldom, if ever, cross and survive. For this reason, each Argentine ant supercolony acts as virtually a sibling species.

This forms part of the larger Volcanic Global Risk Identification and Analysis Project (VOGRIPA), and also forms part of the Global Volcano Model (GVM) initiative (www.globalvolcanomodel.org). A flexible search tool allows users to select data on a global, regional or local scale; the selected data can be downloaded into a spreadsheet. The database is publicly available online at www.bgs.ac.uk/vogripa and currently contains information on nearly 3,000 volcanoes and over 1,800 Quaternary eruption records. Not all volcanoes currently have eruptions associated with them but have been included to allow for easy expansion of the database as more data are found. Data fields include: magnitude, Volcanic Explosivity Index (VEI), deposit volumes, eruption dates, and rock type. The scientific community is invited to contribute new data and also alert the database manager to potentially incorrect data. Whilst the database currently focuses only on large magnitude eruptions, it will be expanded to include data specifically relating to the principal volcanic hazards (e.g. pyroclastic flows, tephra fall, lahars, debris avalanches, ballistics), as well as vulnerability (e.g. population figures, building type) to facilitate risk assessments of future eruptions.

These data suggest subregional variability in Delta R, ranging from 148+ or -46 (super 14) Cyr on the Potomac River to -109+ or -38 (super 14) Cyr at Swan Point, Maryland. The Delta R weighted mean for the Chesapeake's Western Shore (129+ or -22 (super 14) Cyr) is substantially higher than the Eastern Shore (-88+ or -23 (super 14) Cyr), with outer Atlantic Coast samples falling between these values (106+ or -46 and 2+ or -46 (super 14) Cyr). These differences may result from a combination of factors, including (super 14) C-depleted freshwater that enters the bay from some if its drainages, (super 14) C-depleted seawater that enters the bay at its mouth, and/or biological carbon recycling. We advocate using different subregional Delta R corrections when calibrating (super 14) C dates on aquatic specimens from the Chesapeake Bay and coastal Middle Atlantic region of North America.

The key is based solely on their morphology, patterns of body segmentation, numbers of appendages, and mode of locomotion. An effort has been made to treat all traditionally named larval forms, both planktonic and benthic. It is intended that this key be useful for a researcher working with archived museum specimens and therefore, does not include habitat information as a identifying trait, even though this information is usually available in the archived records. Within the phylum Arthropoda there are two sub-phyla and eleven classes having larval stages in the marine environment. Where feasible the original names of the various larval types have been used. Because this nomenclature is less commonly used today compared to the past, the more recent taxonomic affinities are included in parentheses after the original larval name.

Achelia cuneatis Child, 1999 is an example of a typical protonymphon larva in having three pairs of three segmented appendages, cheliphores, palps and ovigerous appendages. Ammothea gigantea Gordon, 1932 is an example of a lecfthotrophic protonymphon larva, having the three pair of appendages phis buds of the first walking legs. Ammothea gigantea is the third species known to have this larval type. The Achelia cuneatis protonymphon larvae is oval, 150 urn long and characterized by a relatively long spinneret spine arising at the distal end of the first segment of each cheliphore. Spines also arise from the distal end of the first segment of the second and third limbs. This typical protonymphon larva of Achelia cuneatis has few yolk granules. The lecithotrophic protonymphon of Ammothea gigantea lacks a spinneret spine on the cheliphore; the larva is oval in shape, but much larger than Achelia cuneatis with a length of 700 um. Its second limb is much larger than the third limb on the first post-embryonic stage, and the third limb is further reduced to a spine-like structure on the second post-embryonic stage.

Evidence of dramatic climate variability, cooling, and aridity over the past six million years has stimulated research about whether environmental change has been a major causal factor in the development of our species' defining characteristics. Examples pertaining to the evolution of bipedality, earliest known toolmaking, dispersal of Homo erectus, extinction of Neanderthals, and the global spread H. sapiens all point to the emergence of adaptability in response to environmental uncertainty as a recurrent theme in human evolution. A synthesis of African paleoclimate data suggests that significant events in human origins tended to occur during lengthy eras of strong climate fluctuation. Human adaptability will continue to be tested as societies face the challenges of adjusting to unprecedented change in Earth's environmental dynamics. Adapted from the source document.

Habitat loss due to fire suppression led to population declines to fewer than 200 males during the 1970s. Subsequent conservation management has allowed the species to recover to over 1700 males by 2010. In this study, we directly examine the impact that low population sizes have had on genetic variation in Kirtland's warblers. We compare the molecular variation of samples collected in Oscoda County, Michigan across three time periods: 1903-1912, 1929-1955 and 2008-2009. Results: In a hierarchical rarified sample of 20 genes and one time period, allelic richness was highest in 1903-1912 sample (a sub(r) = 5.96), followed by the 1929-1955 sample (a sub(r) = 5.74), and was lowest in the 2008-2009 sample (a sub(r) = 5.54). Heterozygosity measures were not different between the 1929-1955 and 2008-2009 samples, but were lower in the 1903-1912 sample. Under some models, a genetic bottleneck signature was present in the 1929-1955 and 2008-2009 samples but not in the 1903-1912 sample. Conclusions: We suggest that these temporal genetic patterns are the result of the declining Kirtland's warbler population compressing into available habitat and a consequence of existing at low numbers for several decades.

These pellets are preserved as calcareous nodules full of fossil mammal bones that are either discrete, bordered by green claystone matrix, or coalesced flattened masses that likely represent coalesced strigilites. The Orellan owl pellet locality has yielded the type specimens of the sciurid rodent Cedromus wilsoni and the todid bird Palaeotodus emryi. The owl pellet assemblage also includes the skeletons, bearing skulls, of at least three individual owls, which strongly reinforces the interpretation of these small masses of bone as owl pellets. These owls were not prey items and are large enough to have preyed on the mouse-sized rodents (eomyids and heteromyids) and on the mouse-sized marsupials, which together constitute the overwhelming number (more than 90%) of prey individuals in the owl pellet assemblage. The strigilites in the assemblage display many of the features deemed characteristic of recent owl pellets based on actualistic studies, including abundant and high quality bone preservation, extreme inequitability of species distribution, intact skulls, numerous mandibles and femora and good representation of all skeletal parts. Further preparation of the bones in the Orellan strigilites is needed to quantify species abundance, bone element frequencies and the statistics of element breakage and completeness, among other data. Nevertheless, the Orellan strigilites are apparently the oldest and one of the few unambiguous published records of fossil owl pellets. Indeed, despite repeated claims that owl pellets are important contributors to the Tertiary microvertebrate fossil record, very few fossil owl pellets have been documented. We conclude that owl pellets are not a significant component of the Tertiary fossil record despite their abundance in some Quaternary deposits.

Here, approximately 50 coprolites were collected from a single horizon stratigraphically low in the late Eocene (Ergilian land-mammal "age") Aksyir svita. Two morphologies are present within the coprolite sample: (1) relatively large coprolites (diameter and length generally >20 mm) with rounded ends and cylindrical cross sections and (2) relatively small coprolites (length approximately 16-23 mm, maximum diameter 9-16 mm) that are rounded in shape. The larger coprolites are assigned to the ichnotaxon Eucoprus, whereas the smaller coprolites are assigned to Alococopros triassicus. The presence of the coprolites in lacustrine shoreline facies, co-occurrence of crocodylian body fossils in the coprolite-bearing strata and the similarity in shape and texture to modern crocodylian feces and lack of bony inclusions suggests a crocodylian producer for the Aksyir svita sample. The variation in their morphology, here assigned to two ichnotaxa, underscores the lack of a single, distinctive crocodylian coprolite morphology.

We report geochronological (six U/Pb LA-ICP-MS zircon ages) and geochemical (19 XRF and ICP-MS analyses) data from the Isthmus of Panama that allow definition of a distinctive succession of plateau sequences to subduction-related protoarc to arc volcaniclastic rocks intruded by Late Cretaceous to middle Eocene intermediate plutonic rocks (67.6 + or - 1.4 Ma to 41.1 + or - 0.7 Ma). Paleomagnetic analyses (24 sites, 192 cores) in this same belt reveal large counterclockwise vertical-axis rotations (70.9 degrees + or - 6.7 degrees ), and moderate clockwise rotations (between 40 degrees + or - 4.1 degrees and 56.2 degrees + or - 11.1 degrees ) on either side of an east-west trending fault at the apex of the Isthmus (Rio Gatun Fault), consistent with Isthmus curvature. An Oligocene-Miocene arc crosscuts the older, deformed and segmented arc sequences, and shows no significant vertical-axis rotation or deformation. There are three main stages of deformation: 1) left-lateral, strike-slip offset of the arc ( approximately 100 km), and counterclockwise vertical-axis rotation of western arc segments between 38 and 28 Ma; 2) clockwise rotation of central arc segments between 28 and 25 Ma; and 3) orocline tightening after 25 Ma. When this reconstruction is placed in a global plate tectonic framework, and published exhumation data is added, the Central American seaway disappears at 15 Ma, suggesting that by the time of northern hemisphere glaciation, deep-water circulation had long been severed in Central America.

It is also home to 300,000 Tibetan pastoralists. The area is characterized by its significant ecological service, unique culture, and fragile ecosystems, and has undergone a rapid degradation over the past several decades. Traditional Tibetan culture offers alternative knowledge and perspectives that facilitate the environmental conservation throughout the region, but have yet to be recognized or adopted by the Chinese government. Beginning in 2007, the local environmental NGO, Shanshui Conservation Center, has initiated a journey to bridge Tibetan communities with the outside scientific community, mainstream society and policy-makers with the aim of advocating integrating traditional Tibetan practices in conservation actions in the Sanjiangyuan region. Through the conservation concession program initiated and facilitated by Shanshui Conservation Center in collaboration with Conservation International, the Sanjiangyuan nature reserve turned over the management of some reserve lands to local communities after a conservation agreement with clear management plans and monitoring indictors was made between the two parties. The trial and demonstration of the conservation concession program successfully led to the adoption of community-based conservation models in state level conservation policy in 2011. We demonstrate as a bridging organization, Shanshui Conservation Center plays the role of cultural translator to promote the understanding and appreciation of traditional Tibetan culture in conservation in western China.

ER - TY - JOUR T1 - Interplanetary dust detection by radio antennas; mass calibration and fluxes measured by STEREO/WAVES AN - 1312836826; 2013-022759 AB - We analyze dust impacts recorded by the S/WAVES radio instrument onboard the two STEREO spacecraft near 1 A.U. during the period 2007-2010. The impact of a dust particle on a spacecraft produces a plasma cloud whose associated electric field can be detected by on-board electric antennas. For this study we use the electric potential time series recorded by the waveform sampler of the instrument. The high time resolution and long sampling times of this measurement enable us to deduce considerably more information than in previous studies based on the dynamic power spectra provided by the same instrument or by radio instruments onboard other spacecraft. The large detection area compared to conventional dust detectors provides flux data with a better statistics. We show that the dust-generated signals are of two kinds, corresponding to impacts of dust from distinctly different mass ranges. We propose calibration formulas for these signals and show that we are able to use S/WAVES as a dust detector with convincing results both in the nanometer and micrometer size ranges. In the latter, the orbital motion of the spacecraft enables us to distinguish between interstellar and interplanetary dust components. Our measurements cover the mass intervals approximately 10 (super -22) -10 (super -20) kg and approximately 10 (super -17) -5X10 (super -16) kg. The flux of the larger dust agrees with measurements of other instruments on different spacecraft.

Although several California persons wanted possession of the meteorite for various California institutions, under the powers of the 1906 Antiquities Act meteorites found on US federal lands were typically transferred to the US National Museum at the Smithsonian Institution and accessioned into the National Collection of Meteorites. With authorization from the US Department of Agriculture, the Smithsonian began a correspondence with one of the meteorite's finders to arrange for its retrieval. But the situation became complicated and controversial when meteorite collector/dealer Harvey H. Nininger (1887-1986), who harboured hopes that the meteorite might be on a parcel of private land in the National Forest, falsely presented himself to the finder as a Smithsonian agent, and was taken to the site of the meteorite. A survey showed the meteorite was on federal land, however, and the Smithsonian reluctantly allowed Nininger to oversee its recovery. During the time that the meteorite was on loan from the Smithsonian and on exhibit at the San Francisco World's Fair, considerable pressure from various California individuals and institutions was put on the Smithsonian to keep the meteorite in California, but it was accessioned into the Smithsonian's National Collection of Meteorites and shipped to Washington, DC. The controversial history of the Goose Lake meteorite affirmed the applicability of the Antiquities Act with regard to the disposition of meteorites found on US federal lands, and set the stage for the later court rulings involving the Old Woman meteorite, a large (2,753 kg) iron found on government land in California in 1976. Problematic ownership issues like those involving the Goose Lake meteorite exist in other countries besides the United States, and in other branches of natural history, especially paleontology. The Goose Lake meteorite is famous for its numerous and enigmatic large holes and cavities, and is a popular attraction at the Smithsonian's National Museum of Natural History in Washington, DC.

GCR fluxes remain at the highest levels ever observed during the space age. One of the largest SEP events observed by CRaTER during the LRO mission occurred on June 7, 2011. We compare model predictions by the Earth-Moon-Mars Radiation Environment Module (EMMREM) for both dose rates from GCRs and SEPs during this event with results from CRaTER. We find agreement between these models and the CRaTER dose rates, which together demonstrate the accuracy of EMMREM, and its suitability for a real-time space weather system. We utilize CRaTER to test forecasts made by the Relativistic Electron Alert System for Exploration (REleASE), which successfully predicts the June 7th event. At the maximum CRaTER-observed GCR dose rate ( approximately 11.7 cGy/yr where Gy is a unit indicating energy deposition per unit mass, 1 Gy = 1 J/kg), GCRs deposit approximately 88 eV/molecule in water over 4 billion years, causing significant change in molecular composition and physical structure (e.g., density, color, crystallinity) of water ice, loss of molecular hydrogen, and production of more complex molecules linking carbon and other elements in the irradiated ice. This shows that space weathering by GCRs may be extremely important for chemical evolution of ice on the Moon. Thus, we show comprehensive observations from the CRaTER instrument on the Lunar Reconnaissance Orbiter that characterizes the radiation environment and space weathering on the Moon.

Topography derived from LRO Camera stereo images and Lunar Orbiter Laser Altimeter (LOLA) ranging is used to measure the relief and analyze the morphology of previously known and newly detected low and high latitude lobate scarps. The asymmetric profiles and maximum slopes on scarp faces ( approximately 5 degrees to 29 degrees ) of lunar lobate scarps are similar to those of lobate scarps observed on Mars and Mercury. Scarp lengths range from approximately 0.6 to 21.6 km (mean = approximately 6.0 km, median = approximately 4.4 km, n = 79), and measured relief ranges from approximately 5 to 150 m (mean = approximately 35 m, median = approximately 20 m, n = 26). Assuming a range of 20 degrees to 40 degrees for the fault plane dip, estimated lower limits for the horizontal shortening (S) expressed by the lobate scarp thrust faults range from approximately 10 to 410 m. The range in S estimated for the lunar scarps is roughly an order of magnitude lower than estimates of S for lobate scarp thrust faults on Mars and Mercury. The relatively small range of S estimated for the growing number of well-characterized lunar scarps is consistent with a small amount of global contraction.

Many of these "ghost" craters and basins contain interior graben of diverse widths and orientations. Here we use finite element models to test a variety of mechanisms for the formation of these graben and ridges. Results show that graben are best explained by cooling of large thicknesses of flood lavas within the craters and basins; conservation of surface area during cooling induces the required extensional stress state. In contrast, the development of wrinkle-ridge rings is best explained as the result of cooling and contraction of Mercury's interior, during which a reduction in Mercury's surface area led to a compressional state of stress. The critical factor in determining where large graben form is the thickness of the youngest cooling unit, the topmost sequence of lavas that cooled coevally. A thicker cooling unit leads to a deeper initiation of normal faulting (wider graben floors). Consistent with observations, the widest graben are predicted to occur where pooled lavas were thickest, and no graben are predicted within generally thinner plains outside of major craters. Observed concentrically oriented graben can be explained by variations in the thickness of the youngest cooling unit. In contrast, none of the basin uplift mechanisms considered, including isostatic response to crater topography, inward flow of the lower crust, or exterior loading by volcanic plains, can account for concentrically oriented graben.

The surface footprints of these measurements are categorized according to geological terrain. Northern smooth plains deposits and the plains interior to the Caloris basin differ compositionally from older terrain on Mercury. The older terrain generally has higher Mg/Si, S/Si, and Ca/Si ratios, and a lower Al/Si ratio than the smooth plains. Mercury's surface mineralogy is likely dominated by high-Mg mafic minerals (e.g., enstatite), plagioclase feldspar, and lesser amounts of Ca, Mg, and/or Fe sulfides (e.g., oldhamite). The compositional difference between the volcanic smooth plains and the older terrain reflects different abundances of these minerals and points to the crystallization of the smooth plains from a more chemically evolved magma source. High-degree partial melts of enstatite chondrite material provide a generally good compositional and mineralogical match for much of the surface of Mercury. An exception is Fe, for which the low surface abundance on Mercury is still higher than that of melts from enstatite chondrites and may indicate an exogenous contribution from meteoroid impacts.

Conversion of the K gamma-ray count rates to elemental abundances on the surface reveals variations from 300 to 2400 ppm. A comparison of these abundances with models for the maximum surface temperature suggests the possibility that a temperature-related process is controlling the K abundances on the surface as well as providing K to the exosphere. The abundances of K and Th have been determined for several geologically distinct regions, including Mercury's northern smooth plains and the plains interior to the Caloris basin. The lack of a significant variation in the measured Th abundances suggests that there may be considerable variability in the K/Th abundance ratio over the mapped regions.

GCRs are high-energy particles capable of smashing atomic nuclei in the lunar regolith and producing a shower of energetic protons, neutrons and other subatomic particles. Secondary particles that are ejected out of the regolith become "albedo" particles. The neutron albedo has been used to study the hydrogen content of the lunar regolith, which motivates our study of albedo protons. In principle, the albedo protons should vary as a function of the input GCR source and possibly as a result of surface composition and properties. During the LRO mission, the total detection rate of albedo protons between 60 MeV and 150 MeV has been declining since 2009 in parallel with the decline in the galactic cosmic ray flux, which validates the concept of an albedo proton source. On the other hand, the average yield of albedo protons has been increasing as the galactic cosmic ray spectrum has been hardening, consistent with a disproportionately stronger modulation of lower energy GCRs as solar activity increases. We construct the first map of the normalized albedo proton emission rate from the lunar surface to look for any albedo variation that correlates with surface features. The map is consistent with a spatially uniform albedo proton yield to within statistical uncertainties.

Three main units are observed on the floor of the depression (2.9 km across, < or =64 m deep) located at the summit of a low-shield volcano: irregularly shaped mounds up to 20 m tall, a lower unit 1 to 5 m in relief that surrounds the mounds, and blocky material. Analyses of Lunar Reconnaissance Orbiter Camera images and topography show that features in Ina are morphologically similar to terrestrial inflated lava flows. Comparison of these unusual lunar mounds and possible terrestrial analogs leads us to hypothesize that features in Ina were formed through lava flow inflation processes. While the source of the lava remains unclear, this new model suggests that as the mounds inflated, breakouts along their margins served as sources for surface flows that created the lower morphologic unit. Over time, mass wasting of both morphologic units has exposed fresh surfaces observed in the blocky unit. Ina is different than the terrestrial analogs presented in this study in that the lunar features formed within a depression, no vent sources are observed, and no cracks are observed on the mounds. However, lava flow inflation processes explain many of the morphologic relationships observed in Ina and are proposed to be analogous with inflated lava flows on Earth.

The Si abundance was determined and used to normalize those of the other reported elements. The Na analysis provides the first abundance estimate of 2.9 + or - 0.1 wt% for this element on Mercury's surface. The other elemental results (S/Si = 0.092 + or - 0 .015, Ca/Si = 0.24 + or - 0. 05, and Fe/Si = 0.077 + or - 0 .013) are consistent with those previously obtained by the MESSENGER X-Ray Spectrometer, including the high sulfur and low iron abundances. Because of different sampling depths for the two techniques, this agreement indicates that Mercury's regolith is, on average, homogenous to a depth of tens of centimeters. The elemental results from gamma-ray and X-ray spectrometry are most consistent with petrologic models suggesting that Mercury's surface is dominated by Mg-rich silicates. We also compare the results with those obtained during the MESSENGER flybys and with ground-based observations of Mercury's surface and exosphere.

Cosmogenic radionuclide abundances indicate that the samples are paired and that they constituted an approximately 1 m (diameter) meteoroid prior to atmospheric entry. At about 1 m in diameter, the PCA 02 HED group represents one of the largest single pre-atmospheric pieces of the Vestan surface yet described. Mineral and textural variations were measured in six of the PCA 02 howardites to investigate meter-scale diversity of the Vestan surface. Mineral compositions span the range of known eucrite and diogenite compositions. Additional non-diogenitic groups of Mg- and Fe-rich olivine are observed, and are interpreted to have been formed by exogenic contamination and impact melting, respectively. These howardites contain olivine-rich impact melts that likely formed from dunite- and harzburgite-rich target rocks. Containing the first recognized olivine-rich HED impact melts, these samples provide meteoritic evidence that olivine-rich lithologies have been exposed on the surface of Vesta. Finally, we present a new method for mapping distributions of lithologies in howardites using 8 elemental X-ray maps. Proportions of diogenite and eucrite vary considerably among the PCA 02 howardites, suggesting they originated from a heterogeneous portion of the Vestan surface. While whole sample modes are dominated by diogenite, the finer grain size fractions are consistently more eucritic. This discrepancy has implications for near-infrared spectral observations of portions of Vesta's surface that are similar to the PCA 02 howardites, as the finer grained eucritic material will disproportionately dominate the spectra.

The question of the ownership of the 2753 kg group IIAB meteorite, the second largest ever found in the United States (34 degrees 28'N, 115 degrees 14'W), gave rise to disputes involving the finders, the Bureau of Land Management, the Secretary of the Department of the Interior, the State of California, the California members of the U.S. Congress, various museums in California, the Smithsonian Institution, and the Department of Justice. Ultimately, ownership of the meteorite was transferred to the Smithsonian under the powers of the 1906 Antiquities Act, a ruling upheld in a U.S. District Court and a U.S. Court of Appeals. After additional debate, the Smithsonian removed a large cut for study and curation, and for disbursement of specimens to qualified researchers. The main mass was then returned to California on long-term loan to the Bureau of Land Management's Desert Discovery Center in Barstow. The Old Woman meteorite litigation served as an important test case for the ownership and control of meteorites found on federal lands. The Old Woman meteorite appears to be structurally unique in containing both hexahedral and coarsest octahedral structures in the same mass, unique oriented schreibersites within hexahedral areas, and polycrystalline parent austenite crystals. These structures suggest that different portions of the meteorite may have transformed via different mechanisms upon subsolidus cooling, making the large slices of Old Woman promising targets for future research.

Analog compositions included a 1425 degrees C partial melt of the Indarch (EH4) meteorite and a range of Mg-rich terrestrial rocks (magnesian basalt, basaltic komatiite, and peridotitic komatiite). All models were held at the iron-wustite buffer to simulate the reducing conditions that likely existed during Mercury's formation. We then compared modeled mineral compositions and abundances, liquidus temperatures, and viscosities to better constrain the characteristics of the lavas that erupted on Mercury's surface. Our results show that the surface composition of Mercury is most similar to that of a terrestrial magnesian basalt (with lowered FeO), composed mainly of Mg-rich orthopyroxene and plagioclase. Because the model magmas are Mg-rich, their counterparts on Mercury would have erupted at high temperatures and displayed low viscosities. Producing melts of these compositions would have required high temperatures at the mantle source regions on Mercury. The inferred low-viscosity lavas would have erupted as thin, laterally extensive flows (depending upon their effusion rate) and would be expected to display surficial flow features that might be preserved to the present.

Detailed geologic mapping, tecto-sedimentological studies using provenance, biostratigraphy and termochronological data conducted in several basins with Paleogene strata across the present Eastern Cordillera, Llanos Basin and Perija Range indicate that reactivation of former normal faults broke the single Upper Cretaceous basin into different depocenters separated by low-amplitude uplifts. Those uplifts exposed dominantly Cretaceous sedimentary cover. In the Paleocene to early Eocene, reverse reactivation broke the syn-orogenic basin into two depocenters. The western depocenter (Magdalena and Rancheria basins) was bounded to the west by eastward-tilted crustal blocks (Central Cordillera and Santa Marta Massif); crustal tilting and Paleocene magmatism were associated to subduction of the buoyant Caribbean plate. Crustal tilting favored reverse reactivation of the western border of former extensional Cretaceous basins. These reactivated structures acted as the eastern boundary of the western depocenter. Terrigenous and magmatic detritus filling the western depocenter were derived mainly from the Central Cordillera and from the uplifts to the east. In Late Paleocene to Early Eocene time, as eastern subduction of the Caribbean plate continued, reactivation of older structures migrated eastward and disrupted the eastern depocenter (presently along the axial zone of the Eastern Cordillera, Llanos foothills, Llanos, Catatumbo and western Maracaibo basin). The Eastern depocenter extended up to the present Llanos basin with minor uplifts, but in the Llanos basin such uplifts could expose Paleozoic metamorphic and sedimentary rocks. However, for most of the eastern depocenter, terrigenous detritus were derived from sources to the west and south, and they included reworking of the western synorogenic clastic wedge and erosion of the Cretaceous sedimentary cover. This Paleocene configuration of low-amplitude uplifts that separated at least two major syn-orogenic depocenters is not similar to the present configuration of the Eastern Cordillera, and differs from the alternative hypothesis of a continuous synorogenic basin that extended from the Central Cordillera to the Guyana shield. Future kinematic restoration of the Eastern Cordillera and Perija Range requires a deformed stage for Paleocene time.

Migratory birds may be especially vulnerable because of the wide range of geographic areas that they depend on throughout the annual cycle. We examined the potential effects of non-breeding season climate change on the breeding biology of Kirtland's Warbler (Setophaga kirtlandii, formerly Dendroica kirtlandii), an endangered songbird that breeds in the Northern Lower Peninsula of Michigan and winters in the Bahamas. Our objectives were to determine whether spring arrival dates on the breeding grounds correlate with late winter rainfall in non-breeding areas and whether this has consequences for reproductive success. We used data on spring arrival dates and number of fledglings per year, sampling many individuals across multiple years, to show that males arrive on breeding grounds later following drier winters. There was a strong male age * rainfall interaction, which indicates that first-time breeders were much more sensitive to changes in rainfall than experienced adults. Regardless of age, however, drier winters and delayed arrival and nest initiation were significantly associated with fewer offspring fledged. These results are important because the Caribbean region is currently experiencing a significant drying trend, and climate change models predict that the severity of this drought will continue to increase. Any resulting adjustments to the timing of migration could constrain spring arrival dates and limit reproductive success for the endangered Kirtland's Warbler, as well as other Neotropical migrants wintering in the Caribbean.

This formation is a very important oil reservoir in the Middle Magdalena Valley Basin, which is a product of the fragmentation of a Cenozoic foreland basin by the uplift of the Northern Andes. The lateral continuity of the formation, as well as its correlations with lithostratigraphic units in adjacent basins is not clearly understood. The Los Corros Fossil Horizon, a molluscan horizon in the upper part of the Esmeraldas Formation, has been used to trace the top of the formation. This horizon is not laterally continuous over the basin and its age is still debatable. Data from 82 samples from an outcrop section in the Nuevo Mundo Syncline area and from seven previously studied wells have been integrated with a palynological zonation of northern South America in order to date the Esmeraldas Formation. The age ranges from the late Early Eocene to the Late Eocene. The Esmeraldas Formation is correlative with the upper Picacho Formation and the lower part of the Concentracion Formation in the Eastern Cordillera, and the upper Mirador Formation and the base of the Carbonera Formation in the Llanos Foothills. The Los Corros Fossil Horizon is Late Eocene and is time-correlative with a marine transgression in the central Llanos Foothills. A non-metric multidimensional scaling analysis suggests that floras from the Middle Magdalena Valley were different from those in the Llanos Foothills area during the Middle to Late Eocene. This is apparently due to taphonomic effects. The results of this study will contribute to a better understanding of the overall evolution of the Middle Magdalena Valley Basin.

A new species of Aegypius, A. jinniushanensis, is erected and characterized by possessing a less developed processus zygomaticus and processus suprameaticus, as well as a relatively larger condylus occipitalis, compared with A. monachus. Another specimen, assigned to Torgos, is the first record of this genus from outside Africa. The presence of two large vultures, apparently in the same feeding group, in the Jinniushan faunal assemblage suggests that there were more opportunities for interspecific competition among scavengers in the middle Pleistocene of northeastern China than at present. By analogy with phylogenetically related modern vultures, we suggest that niche differentiation between the two extinct species may have reduced the degree of competition between them. The disappearance of the genus Torgos from northeast China might be the result of the Pleistocene extinction of a suite of large mammalian herbivores, and the loss of grassland and savannah from this region.

Unfortunately, forelimb elements are rarely preserved and thus the basic structure of the abelisaurid forelimb remains poorly understood. Until recently, the Upper Cretaceous Maevarano Formation of northwestern Madagascar has produced numerous exceptional specimens of the abelisaurid theropod Majungasaurus crenatissimus but comparatively little forelimb material. A recently discovered articulated skeleton of Majungasaurus preserves a virtually complete pectoral girdle and forelimb, which, along with additional isolated forelimb elements, affords important new insights into the structure of these elements. New specimens of the scapulocoracoid and humerus allow more detailed description of their morphology, and antebrachial and manual elements are described for the first time. The radius and ulna are approximately one-quarter the length of the humerus and both have expanded proximal and distal articular surfaces relative to their narrow diaphyses. The manus consists of four digits, each composed of a short metacarpal and one (digits I and IV) or two (digits II and III) phalanges. No ossified carpals are present. The proportions of the brachium and antebrachium are stout, more similar to the condition in Carnotaurus than in Aucasaurus. We reinterpret manual digit identities in Aucasaurus and Carnotaurus based on new information provided by the manus of Majungasaurus. Overall, the morphology of the forelimb in Majungasaurus reveals that abelisaurids share an extremely reduced, unique morphology that is dissimilar to the more typical theropod condition seen in other ceratosaurs.

Apparent mutualism results when multiple prey species reduce predation risk for each other by altering a predator's functional response. Short-term apparent competition occurs when multiple prey species increase predation risks for each other through the numerical response, i.e. increasing the predator's birth rate, or aggregative response, i.e. attracting a higher density of predators. Our objectives in this study were to determine the aggregative response and 2-prey functional response of a predator and to examine indirect effects over a range of prey densities. We used the clam Macoma balthica and juvenile blue crabs Callinectes sapidus as prey for adult blue crabs. In laboratory experiments, we determined the single-prey functional responses of the crabs to each prey species and the 2-prey functional response. We combined the 2-prey functional response with the known blue crab aggregative response to clams to estimate field predation rates. Our model predicts that at low prey densities, clams and juvenile blue crabs exhibit apparent mutualism, whereas at high clam densities, this relation switches to short-term apparent competition. These unexpected results highlight the need to incorporate multiple aspects of predation at multiple scales when considering indirect effects.

Variability in the light-saturated photosynthetic rate, P super(B) sub(m)ax, was partitioned into interannual, seasonal, and spatial components. The seasonal component of the variance was greatest, followed by interannual and then spatial. Physiological models of P super(B) sub(m)ax based on balanced growth or photoacclimation predicted the overall mean and most of the range, but not individual observations, and failed to capture important features of the seasonal and interannual variability. P super(B) sub(m)ax correlated most strongly with temperature and the concentration of dissolved inorganic carbon (IC), with lesser correlations with chlorophyll a, diffuse attenuation coefficient, and a principal component of the species composition. In statistical models, temperature and IC correlated best with the seasonal pattern, but temperature peaked in late July, out of phase with P super(B) sub(m)ax, which peaked in September, coincident with the maximum in monthly averaged IC concentration. In contrast with the seasonal pattern, temperature did not contribute to interannual variation, which instead was governed by IC and the additional lesser correlates. Spatial variation was relatively weak and uncorrelated with ancillary measurements. The results demonstrate that both the overall distribution of P super(B) sub(m)ax and its relationship with environmental correlates may vary from year to year. Coefficients in empirical statistical models became stable after including 7 to 10 yr of data.

We examined how variation in food availability affects growth rates and therefore influences size at sex change in 2 protandrous calyptraeid gastropods, Crepidula cf. marginalis and C. incurva. The lowest food concentration tested resulted in starvation and was discarded. The medium and high food concentrations resulted in differences in growth rates, and in both species the penis was lost and sex change was initiated at larger sizes with more food. However, food concentration had little effect on the size at which the female stage was attained. Food-induced alterations in the timing of sex change were not in the expected direction. C. cf. marginalis raised with less food initiated sex change earlier, but completed sex change later in time than those raised with more food. C. incurva both initiated and completed sex change later when raised with less food compared to those individuals raised with more food. In both species the transitional phase was completed more rapidly with more food. These results are consistent with the idea that, as more resources become available, time dedicated to active sexual phases is maximized and the duration of the non-reproductive transitional phase is minimized. Under 'good' conditions this is manifest by a delay in the loss of the male phase, but no change in the attainment of the female phase.

Most data were collected by GPS-collar technology, which yielded over 37,000 locations in 27 collar deployments on 10 individuals. The eight chapters introduce the study area and methods (1) and describe daily and seasonal activity (2); movements and ranges (3); diet and energetics (4); social interactions and reproduction (5); disease exposure, morbidity and mortality (6); maned wolf conservation (7); and finally, we synthesize the results in an overview of maned wolf behavioral ecology, with hypotheses about the unique form and function of this atypical canid (8). Activity was temperature related and sharply nocturnal in the dry season but partly diurnal in the rainy season. Adult home ranges were 40-123 km super(2), with strong seasonal variations in land use. Maned wolves averaged 14 km/night travel in dry months and 7 km/night during wet months. Breeding pairs shared territories with contiguous borders, which did not overlap with neighboring pairs. Young females twice stayed until adulthood on natal territories, as presumed helpers, and acquired the territory upon disappearance/death of the adult females. Females were the holders of territories into which males moved to form pairs. Young males all emigrated. By 8 years old, maned wolves showed extreme tooth wear, and dental disease was a major cause of morbidity. Habitat loss is the chief conservation issue for the species, but drought-related resource loss appears to be reducing the study area population.Original Abstract: Estudiamos la ecologia de los lobos de crin (Canidae: Chrysocyon) durante 10 anos en el Parque Nacional Noel Kempff, Bolivia. La mayoria de los datos fueron colectados por la tecnologia GPS-de-collar, que genero mas de 37.000 ubicaciones en 10 individuos. Los ocho capitulos dan a conocer el area de estudio y metodos (1), y describen la actividad diaria y estacional (2), movimientos y rangos (3), dieta y energetica (4), interacciones sociales y reproduction (5), exposicion a enfermedades, morbilidad y mortalidad (6), conservacion del lobo de crin (7) y, finalmente, sintetizamos los resultados con informacion general de la ecologia y comportamiento del lobo de crin, con hipotesis acerca de la singular forma y funcion de este atipico canido. La actividad estuvo relacionada con la temperatura y fue claramente nocturna en la estacion seca, aunque en parte diurna en la temporada de lluvias. El area del territorio de adultos fue de 40--123 km super(2), con marcadas variaciones estacionales en el uso del habitat. El desplazamiento promedio fue de 14 km/noche en los meses secos y 7 km durante los meses humedos. Las parejas reproductoras compartieron territorios con limites contiguos, los cuales no se superpusieron con el de las parejas vecinas. Una hembra joven permanecio en dos ocasiones hasta la edad adulta en su territorio natal, se supone como "helper" y adquirio el territorio, a la desaparicion/muerte de las hembras adultas. Las hembras fueron las duenas de los territorios, en los que los machos se trasladaron para formar parejas. Los machos jovenes emigraron. A los 8 anos de edad, los lobos de crin mostraron desgastes extremos de los dientes, y las enfermedades dentales fueron una importante causa de morbilidad. La perdida de habitat es la amenaza principal para la conservacion de la especie, pero la sequia relacionada con la perdida de recursos parece estar reduciendo las poblaciones del area de estudio.

National Evolutionary Synthesis Center hosted the first Fossil Calibrations Working Group (3-6 March, 2011, Durham, NC, USA), bringing together palaeontologists, molecular evolutionists and bioinformatics experts to present perspectives from disciplines that generate, model and use fossil calibration data. Presentations and discussions focused on channels for interdisciplinary collaboration, best practices for justifying, reporting and using fossil calibrations and roadblocks to synthesis of palaeontological and molecular data. Bioinformatics solutions were proposed, with the primary objective being a new database for vetted fossil calibrations with linkages to existing resources, targeted for a 2012 launch.

Eruption magnitude, the nature of available outcrop, and the resolution and type of data available define the scale of any proposed correlation. Different scales require different approaches to demonstrate, or more accurately, to estimate the likelihood of correlation among two or more deposits. This is emphasized through a probabilistic approach to the correlation of proximal and distal tephra deposits associated with Lower and Middle Paleolithic archaeological sites from central Turkey through the use of discriminant analyses and multiple analyses of variance.

Regardless of cause, strandings also represent a sample of the living community, although their fidelity has rarely been quantified. Using commensurate stranding and sighting records compiled from archived datasets representing nearly every major ocean basin, I demonstrated that the cetacean stranding record faithfully reflects patterns of richness and relative abundance in living communities, especially for coastlines greater than 2000 km and latitudinal gradients greater than 4 degree . Live-dead fidelity metrics from seven different countries indicated that strandings were almost always richer than live surveys; richness also increased with coastline length. Most death assemblages recorded the same ranked relative abundance as living communities, although this correlation decreased in strength and significance at coastline lengths greater than 15 000 km, highlighting the importance of sampling diversity at regional scales. Rarefaction analyses indicated that sampling greater than 10 years generally enhanced the completeness of death assemblages, although protracted temporal sampling did not substitute for sampling over longer coastlines or broader latitudes. Overall, this global live-dead comparison demonstrated that strandings almost always provided better diversity information about extant cetacean communities than live surveys; such archives are therefore relevant for macroecological and palaeobiological studies of cetacean community change through time.

This bird was evidently most closely related to the noddy terns (Anoinae, Anous, Procelsterna). Compared with those genera, the tibiotarsus was much shorter and the ulna much longer in relation to the size of the humerus. The absolute size of the wing was considerably larger than in Anous stolidus, but the sternum was smaller. Aspects of the configuration of the quadrate and mandibular articulation are very distinct from any genus of modern gulls or terns, so that Feducciavis must have had singular feeding habits.

This study quantitatively examined variation in floral phenotypes and pollinator service of Heliconia bihai and H. caribaea across three Antillean islands. The prediction was that floral characters would correspond to the major pollinators of these species on each island. Analysis of floral phenotypes revealed convergence among species and populations of Heliconia from the Greater Antilles. All populations of H. caribaea were similar, characterized by long nectar chambers and short corolla tubes. In contrast, H. bihai populations were strongly divergent: on Dominica, H. bihai had flowers with short nectar chambers and long corollas, whereas on Hispaniola, H. bihai flowers resembled those of H. caribaea with longer nectar chambers and shorter corolla tubes. Morphological variation in floral traits corresponded with geographic differences or similarities in the major pollinators on each island. The Hispaniolan mango, Anthracothorax dominicus, is the principal pollinator of both H. bihai and H. caribaea on Hispaniola; thus, the similarity of floral phenotypes between Heliconia species suggests parallel selective regimes imposed by the principal pollinator. Likewise, divergence between H. bihai populations from Dominica and Hispaniola corresponded with differences in the pollinators visiting this species on the two islands. The study highlights the putative importance of pollinator-mediated selection as driving floral convergence and the evolution of locally-adapted plant variants across a geographic mosaic of pollinator species.

These rocks are compositionally similar to sub-continental lithospheric mantle peridotites and pyroxenites. Wehrlites formed predominantly by fractional crystallization processes within supra-subduction zone magmas and the pyroxenites are generally consistent with segregation and accumulation in similar magmas. Bulk rock ratios of Al (sub 2) O (sub 3) /SiO (sub 2) (0.01-0.03) and MgO/SiO (sub 2) (up to >1) exhibited by the wehrlites and serpentinites indicate crystallization from a refractory source that underwent high degrees of melt extraction. Spinel chemistry confirms this and demonstrates that wehrlite and clinoproxenite protoliths underwent approximately 20-23% and 12-15% partial melting, respectively. Wehrlites and serpentinites also preserve evidence of extensive melt-peridotite interaction manifest as bulk rock SiO (sub 2) -depletions and FeO (super t) -enrichments relative to mantle residua as well as low Mg# (0.39-0.45) spinels with variable Ti contents but constant Cr# (0.42-0.47). These features are identical to those of "impregnated" plagioclase-peridotites of abyssal and sub-continental environments and compositional trends in spinel space imply reaction between secondary, MORB-like melts saturated in olivine + clinopyroxene or olivine and a harzburgitic protolith. High olivine:pyroxene ( nearly equal 3:1) and clinopyroxene:orthopyroxene ratios of the wehrlites coupled with chemical data dictate that reactions entailed orthopyroxene dissolution and olivine recrystallization. All AUC rock types exhibit primitive mantle-normalized incompatible element signatures characterized by LILE-enrichments, high fluid-mobile/immobile element ratios (Sr/Nd, Ba/La and Pb/Ce >> 1) and prominent HFSE (Nb, Zr, and Ti) depletions indicative of generation in a sub-arc environment within a supra-subduction zone system. A candidate for the associated arc-system is the one responsible for nearby arc-related Jurassic granitoids. Southeast-directed thrusting along the Andong Fault System may account for subsequent emplacement of the AUC into the Gyeongsang Basin.

There is little information available, however, on how the production of leaf waxes by different kinds of plants might influence the abundance and isotopic composition of n-alkanes in sedimentary archives. This lack of information increases uncertainty in interpreting n-alkyl lipid abundance and delta (super 13) C signals in ancient settings. We provide here n-alkyl abundance distributions and carbon isotope fractionation data for deciduous and evergreen angiosperm and gymnosperm leaves from 46 tree species, representing 24 families. n-Alkane abundances are significantly higher in angiosperms than gymnosperms; many of the gymnosperm species investigated did not produce any n-alkanes. On average, deciduous angiosperms produce 200 times more n-alkanes than deciduous gymnosperms. Although differences between angiosperms and gymnosperms dominate the variance in n-alkane abundance, leaf life-span is also important, with higher n-alkane abundances in longer-lived leaves. n-Alkanol abundances covary with n-alkanes, but n-alkanoic acids have similar abundances across all plant groups. Isotopic fractionation between leaf tissue and individual alkanes (epsilon (sub lipid) ) varies by as much as 10 ppm among different chain lengths. Overall, epsilon (sub lipid) values are slightly lower (-4.5 ppm) for angiosperm than for gymnosperm (-2.5 ppm) n-alkanes. Angiosperms commonly express slightly higher Delta (sub leaf) (photosynthetic discrimination) relative to gymnosperms under similar growth conditions. As a result, angiosperm n-alkanes are expected to be generally 3-5 ppm more depleted in (super 13) C relative to gymnosperm alkanes for the same locality. Differences in n-alkane production indicate the biomarker record will largely (but not exclusively) reflect angiosperms if both groups were present, and also that evergreen plants will likely be overrepresented compared with deciduous ones. We apply our modern lipid abundance patterns and epsilon (sub lipid) results to constrain the magnitude of the carbon isotope excursion (CIE) at the onset of the Paleocene-Eocene Thermal Maximum (55.8 Ma). When Bighorn Basin (WY) sediment n-alkanes are interpreted in context of floral changes and modern n-alkane production estimates for angiosperms and gymnosperms, the CIE is greater in magnitude (-5.6 ppm) by approximately 1 ppm compared to previous estimates that do not take into account n-alkane production.

The densimetric and thermal Richardson, Froude, Stokes and settling numbers for our experiments match those of natural PDCs. The laboratory currents are fully turbulent, although the experiments have lower Reynolds numbers than PDCs. In sum, our experiments are dynamically similar to natural currents. Comparisons of currents traversing flat topography or encountering barriers show that runout distance is not significantly reduced for currents that traverse barriers with height <1.5 times the current thickness, but currents do not pass taller barriers. Buoyancy reversals occur in most currents, resulting in liftoff and generation of a buoyant plume. Liftoff occurs near the maximum runout distance for currents traveling over flat topography but is focused near or above barriers for currents that encounter barriers. Notably, plume formation above barriers can result in reversal of flow direction downstream of the obstruction as portions of the current flow back and feed the rising plume.

Alteration of the shoreline, either through the replacement of marshes with anthropogenic structures, such as riprap and bulkheads, or through the replacement of the native marsh grass Spartina sp. (Spartina) with the invasive Phragmites australis (Phragmites), may affect the value of this habitat as a nursery. In this study, we compared the effects of four common shoreline types, bulkheads, riprap, Phragmites marshes, and Spartina marshes, on food availability, feeding, growth, and survival of juvenile blue crabs in adjacent subtidal areas, as well as on the abundance and size of predators in the South River, Maryland. Sites with each shoreline type were randomly selected. We used benthic cores to sample macrobenthic prey and performed gut content analysis on caged crabs to examine food availability and feeding. Growth was estimated using caged crabs. Survival was assayed with a tethering experiment and predators were sampled with a seine net. Riprap had a lower abundance of macrofaunal prey, and the macrofaunal community differed from both marsh types in that it had it had smaller an more opportunistic species such as nematodes and small polychaetes compared to more bivalves and larger polychaetes at the marsh sites; however, gut contents and growth did not vary among shoreline types. Predation pressure on juvenile blue crabs was highest at bulkhead sites and lowest at riprap. Predator abundance did not vary among the shoreline types, though piscine predators were smaller in size near Spartina marshes compared to the other shorelines. We conclude that shoreline hardening substantially reduced the value of shoreline habitats for juvenile blue crabs, but that Spartina and Phragmites are functionally equivalent.

Together with the use of rotary core barrel drilling, this expedition was deemed to be unsuitable for paleoceanographic study of sediments/sedimentary rocks. Fortunately, an intriguing suite of Cretaceous pelagic carbonate sediments was recovered from the approximately 80 m-thick interval of Site U1348 on the northern summit of Tamu Massif (Southern High), albeit poor in core recovery and dominated by cherts at some intervals. Available carbonate materials were remarkably unconsolidated, and its softness warranted the sedimentological description as "ooze," meaning that the sediments escaped the normal diagenetic processes since their deposition. Highlights were the recoveries of the oldest known calcareous ooze of early Aptian age (recovered as 22 cm-thick interval in Core 10) and the freshest pelagic sedimentary record of the Santonian-Campanian transition (1.4 m-thick in Core 2). Detailed shore-based studies of calcareous microfossils, isotopic geochemistry (C, O and Sr isotopes), and/or magnetic reversals strengthen the above Cores 2 and 10 shipboard chronology and allow new insights to be presented for Cretaceous paleoceanography. Specifically, new stable isotope data from bulk carbonates and/or individual benthic foraminiferal separates enable us to extend the reliable oxygen isotope record of benthic foraminifera to 120 Ma and to document a hitherto unknown major cooling event around the Santonian-Campanian transition. These new findings also have significant bearing on the future direction of scientific deep-sea drilling. Namely, although Cretaceous pelagic sedimentary records in the central Pacific have been notoriously incomplete due largely to significant burial diagenesis of carbonates as well as silicification, pristine calcareous materials are still anticipated to be present at the summits of seamounts. Such a setting, at least northern Tamu Massif, will be an important target in future paleoceanographic expedition.

X-ray computed tomography (XRCT) and numerical modeling suggest that mixing style is controlled by whether the or not the host magma begins to convect before the intruding magma solidifies; the same two host and intruding magmas can thus form either enclaves or banded pumice depending on the size of the intruding magma body and the temperatures of the magmas. The critical control on mixing is competition between development of crystal networks in the intruding magma and melting and disruption of networks in the host. Consequently, the size of the intruding dike influences mixing style. XRCT analysis demonstrates that banded pumice from the 1915 Mt. Lassen eruption lack crystal networks and hence experienced mixing dominated by fluid flow. In contrast, rhyodacites with mafic enclaves from Chaos Crags contain well-developed networks of large crystals. Our model relies on three assumptions: 1) when magma crystallinity exceeds a critical value, approximately 13 vol.%, the magma develops a yield strength; 2) when crystallinity exceeds 40 vol.% (depending on mineral phase) the magma has a crystal network and is effectively solid; and 3) mixing is initiated by the injection of a hot dike into a cooler magma body with a yield strength. We model the mixing process as a 1-dimensional conductive cooling problem, use MELTS to calculate magma density, phase assemblages, and melt composition, and calculate melt viscosity using the method of Giordano et al. (2008), bulk viscosity using the Einstein-Roscoe equation, and yield strength using the method of Hoover et al. (2001). Importantly, because the two magmas are of different compositions, their crystallinities and viscosities do not have the same variations with temperature. Modeling begins with the instantaneous emplacement of a hot, mafic dike with crystallinity below 30 vol.% in a cooler, more silicic magma with a crystal network. As the intruding magma cools, it crystallizes from the outside in, while simultaneously, host magma temperature near the intruder rises. The onset of mixing occurs when the host magma is heated sufficiently for: 1) disruption of the crystal network and 2) Ra of the host boundary region exceeds the critical value for the onset of convection 657. If the shear stress exerted by the convecting host magma on the dike is greater that the yield strength of the dike margin (and dike crystallinity does not exceed 40%), then fluid mixing occurs, otherwise enclaves form by brittle deformation. Application of the model to magma compositions representative of Lassen and Chaos Crags shows that emplacement of dikes <1 m thick should produce enclaves, whereas thicker dikes should generate fluid mixing and form banded pumice within hours to days of emplacement. Similar relationships apply to other magmatic systems including Pinatubo, Unzen, and Ksudach/Shtuybel' Volcanoes.

Here we describe a distinctive marginal characteristic that is often developed along the margins of endogenously inflated basaltic lava flows; discreet topographic levels of the emplaced lava that are here termed "terraced margins". Terraced margins were first noted at the distal end of the Carrizozo lava flow in central New Mexico, where they are particularly well expressed, but terraces have also been observed along some margins of the McCartys lava flow (NM), the distal end of the 1859 Mauna Loa lava flow (HI), and lava flows at Craters of the Moon (ID). Differential Global Positioning System surveys across several terraced margins reveal consistent topographic characteristics: the upper surface of each terrace level is at roughly one half the height of the sheet lobe from which it emerges; when a terrace becomes the source of an additional outbreak, the upper surface of the second terrace is at roughly one half the height of the source terrace; often a subtle topographic depression is present along the contact between a terrace and its source sheet lobe, suggesting that the terrace outflow starts at a level roughly one-third the height of the source lobe; the upper surfaces of both the source sheet lobe and associated terraces are level to within tens of centimeters across length scales of many tens to hundreds of meters, indicative of inflation of all components. The field observations will be used as the constraints for modeling of the inflation and terracing mechanisms, an effort that has only recently started. The multiple imaging data sets now available for Mars have revealed the presence of terraced margins on some lava flows on Mars. Although detailed topographic data are not currently available for the Martian examples identified so far, the presence of terraced margins for lava flows on both Earth and Mars indicates that the terracing mechanism is intimately associated with the lava flow inflation process.

AN - 1832616015; 638262-67 AB - The primary oxygen fugacity of basaltic melts reflects the mantle source oxidation state, dictates the crystallizing assemblage, and determines how the magma will evolve. On Earth, variabile fO (sub 2) among basaltic melts is linked to mass exchange between the surface and the interior by tectonic processes (subduction). Martian basalts represent samples of the planet's interior and we currently have two data sets with which to work: the Amazonian age shergottitic meteorites and early Hesperian age basaltic rocks examined in situ by the Spirit rover in Gusev Crater. The Gusev basalts are diverse and range from the K-poor Adirondack class (0.02 wt% K (sub 2) O) to K-rich Backstay class (up to 1.2 wt% K (sub 2) O). By combining the Fe (super 3+) /Fe (sub T) of igneous minerals (olivine, pyroxene, and magnetite) determined by Moessbauer spectrometer, we estimated primary fO (sub 2) for the Gusev basalts to be -3.6 to 0.5 Delta QFM (quartz-fayalite-magnetite buffer). General similarity between the fO (sub 2) estimated for the Gusev basalts and ranges in fO (sub 2) for the shergottitic meteorites (-3.8 to 0.2 Delta QFM; Herd, 2003; Goodrich et al., 2003) suggests that the overall range of fO2 for the Martian igneous rocks and mantle is relatively restricted. Also like the shergottites (Herd et al., 2003), estimated fO2 of three Gusev classes (Adirondack, Barnhill and Irvine) correlates with a proxy for LREE enrichment (K/Ti). This suggests mixing between melts or fluids derived from reservoirs with contrasting fO (sub 2) , such as reduced, LREE-depleted mantle and more oxidized, LREE-enriched crust. One exception to this trend is the high-K Backstay class, which has low fO (sub 2) like the low-K Adirondack class (-3.6 Delta QFM). Backstay and Adirondack are probably melts of similarly reduced mantle and contrasting alkali concentrations may reflect partial melting processes. If the high K (sub 2) O (and K/Ti) of Backstay was obtained through partial melting of primary (i.e., never melted) mantle, then its relatively low fO (sub 2) may imply that the development of the more oxidized, LREE-enriched reservoir was not caused by melting processes alone. Instead, the more oxidized, LREE-enriched reservoir may signify high degrees of fractionation, fundamental source heterogeneities formed during planetary differentiation, and/or metasomatism by oxidizing fluids. Based on the available fO (sub 2) data for the Martian interior, tectonic processes have not led to sufficient recycling of oxidized surface material into the Martian interior to entirely affect the overall oxidation state of the mantle. However, the oxygen fugacity of well-characterized samples from Mars would allow us to continue to test this hypothesis. Furthermore, by combining fO (sub 2) with other data sets, such as radiometric ages, rare earth elements and particularly Sm and Nd isotopes, we could model and discuss the development of oxidized and reduced reservoirs in an absolute timeframe.

Qualitative estimates of terrestrial dust devil frequency based upon visual field surveys have varied by several orders of magnitude. We will present the results of our quantitative characterization of the size-frequency distribution (SFD) of terrestrial dust devils, which utilizes stereo photography to calculate dust devil diameters via parallax displacement. In 2009, we conducted field campaigns in Eloy, Arizona and Eldorado Valley, Nevada to survey terrestrial dust devils: the latter site was revisited in 2010. During each survey period, at least two and usually three observers were positioned at spotter stations located approximately 100 m apart, thereby allowing triangular study areas (bounded by three meteorological masts) of A = 0.83 sq. km and A = 0.55 sq. km to be surveyed in Eloy and Eldorado Valley, respectively. Each spotter station was equipped with a tripod-mounted, weatherproof digital camera: whenever possible, any dust devils observed within the study area were photographed simultaneously by camera operators in radio contact. All dust devils observed within the survey sites were assigned a qualitative diameter estimate (i.e., Tiny/Small/Medium/Large) by a third spotter positioned near the center of the study area. Thus even if small dust devils occurred that existed too fleetingly to be photographed, they were still recorded. Methodology: The positions of both survey tripods were measured to nearly equal 0.5 m precision using GPS. In addition, a full 360-degree panorama was generated from each survey position, corrected for lens distortion, and then imported into a GIS. The photographs of dust devils from each camera are then also incorporated into the GIS and aligned against the corresponding background panorama. The width and center points of each dust devil are then digitized and its bearings and angular width outputted from the GIS, together with the time it was photographed. Finally, using simple geometry, the position and width of each dust devil is calculated, converted into UTM coordinates and presented in a map-projected format. Initial results show that our methodology is robust and that reliable data for size and position of dust devils can be extracted. Altogether, we were able to successfully stereo photograph approximately 40% of the more than 1000 dust devils that we observed within the study areas during the three field campaigns. We will use the quantitative parallax-derived dust devil diameter measurements to assess the accuracy of our qualitative size estimates, accounting for a variety of factors such as distance, speed, duration, apparent dustiness, and number of observers. Our analysis will not only yield a more comprehensive SFD for terrestrial dust devils, but will also help constrain SFD parameterizations of Martian dust devils based on orbiter and lander observations.

Typically only tens of meters in relief, these linear or curvilinear topographic rises are interpreted to be low-angle thrust fault scarps resulting from global radial contraction. Radial contraction of the Moon can be inferred from shortening across the population of lobate scarps and is estimated at nearly equal 100 m. However, the geometry and depth of the underlying faults and mechanical properties of the near-surface lunar crustal materials are not well constrained. The Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Cameras (NACs) acquire 0.5 to 2.0 m/pixel panchromatic images and digital terrain models (DTMs) with spatial resolutions of 2 m are derived from NAC stereo pairs. Topographic data are being used to constrain models of the lobate scarp thrust faults. DTMs are analyzed for relief and morphology of the Slipher (48.3 degrees N, 160.6 degrees E), Racah X-1 (10 degrees S, 178 degrees E), and Simpelius-1 (73.5 degrees S, 13 degrees E) scarps. Profiles are extracted, detrended, and compared along strike. LROC Wide Angle Camera (WAC) 100 m/pixel image mosaics and topography provide regional contexts. Using elastic dislocation modeling, the fault dip angles, depths, slip, and taper are each varied until the predicted surface displacement best fits the DTM profiles for each lobate scarp. Preliminary best-fit dip angles vary from 30-40 degrees , maximum fault depths extend to several hundred meters, and the amount of slip varies from 10 to 30 meters for the three scarps. The modeled maximum depths suggest that the thrust faults are not deeply rooted.

Venus is often termed Earth's sister planet, yet they have evolved in strikingly different ways. Venus' surface and atmosphere dynamics, and their complex interaction are poorly constrained. A lander mission to Venus would enable us to address a multitude of outstanding questions regarding the geological evolution of the Venusian atmosphere and crust. Our proposed mission concept, VenUs Lander for Composition ANalysis (VULCAN), is a two-component mission, consisting of a lander and a carrier spacecraft functioning as relay to transmit data to Earth. The total mission duration is 150 days, with primary science obtained during a 1-hour descent through the atmosphere and a 2-hour residence on the Venusian surface. In the atmosphere, the lander will provide new data on atmospheric evolution by measuring dominant and trace gas abundances, light stable isotopes, and noble gas isotopes with a neutral mass spectrometer. It will make important meteorological observations of mid-lower atmospheric dynamics with pressure and temperature sensors and obtain unprecedented, detailed imagery of surface geomorphology and properties with a descent Near-IR/VIS camera. A nepholometer will provide new constraints on the sizes of suspended particulate matter within the lower atmosphere. On the surface, the lander will quantitatively investigate the chemical and mineralogical evolution of the Venusian crust with a LIBS-Raman spectrometer. Planetary differentiation processes recorded in heavy elements will be evaluated using a gamma-ray spectrometer. The lander will also provide the first stereo images for evaluating the geomorphologic/volcanic evolution of the Venusian surface, as well as panoramic views of the sample site using multiple filters, and detailed images of unconsolidated material and rock textures from a microscopic imager. Our mission proposal will enable the construction of a unique Venus test facility that will attract a new generation of scientists to Venus science. With emphasis on flight heritage, we demonstrate our cost basis and risk mitigation strategies to ensure that the VULCAN mission can be conducted within the requirements and constraints of the New Frontiers Program.

Previous workers have measured wrinkle ridge orientations and lengths to investigate their spatial distribution and infer basin-localized stress fields [2,3]. Although these plots include the most prominent mare ridges and their general trends, they may not have fully captured all of the ridges, particularly the smaller-scale ridges. Using Lunar Reconnaissance Orbiter Wide Angle Camera (WAC) global mosaics and derived topography (100m pixel scale) [4], we systematically remapped wrinkle ridges in Mare Serenitatis. By comparing two WAC mosaics with different lighting geometry, and shaded relief maps made from a WAC digital elevation model (DEM) [5], we observed that some ridge segments and some smaller ridges are not visible in previous structure maps [2,3]. In the past, mapping efforts were limited by a fixed Sun direction [6,7]. For systematic mapping we created three shaded relief maps from the WAC DEM with solar azimuth angles of 0 degrees , 45 degrees , and 90 degrees , and a fourth map was created by combining the three shaded reliefs into one, using a simple averaging scheme. Along with the original WAC mosaic and the WAC DEM, these four datasets were imported into ArcGIS, and the mare ridges of Imbrium, Serenitatis, and Tranquillitatis were digitized from each of the six maps. Since the mare ridges are often divided into many ridge segments [8], each major component was digitized separately, as opposed to the ridge as a whole. This strategy enhanced our ability to analyze the lengths, orientations, and abundances of these ridges. After the initial mapping was completed, the six products were viewed together to identify and resolve discrepancies in order to produce a final wrinkle ridge map. Comparing this new mare ridge map with past lunar tectonic maps, we found that many mare ridges were not recorded in the previous works. It was noted in some cases, the lengths and orientations of previously digitized ridges were different than those of the ridges digitized in this study. This method of multi-map digitizing allows for a greater accuracy in spatial characterization of mare ridges than previous methods. We intend to map mare ridges on a global scale, creating a more comprehensive ridge map due to higher resolution. References Cited: [1] Schultz P.H. (1976) Moon Morphology, 308. [2] Wilhelms D.E.

The features all have roughly similar-appearing planforms even though they represent drastically different emplacement mechanisms. Cross-sectional profiles were measured for the three types of feature using multiple techniques of surveying in order to obtain comparable precisions for features whose horizontal scale ranges over more than three orders of magnitude. When the measured profiles are scaled by the width of the feature, defined here to be the distance between the basal break in slope on both sides of the crest, the scaled profiles can be separated according to their process. When detailed topographic information can be obtained from images of various aeolian features on Mars, such as photoclinometric derivation of shape from shading, the width-scaled terrestrial data provide a method for remotely evaluating the probable mechanism of origin for the Martian features. Application of this technique to planetary settings is limited primarily by the precision of topography that can be obtained remotely for planetary surfaces, but at least for Mars, the diverse data sets available from multiple spacecraft platforms are providing data that can be compared favorably to the measured terrestrial data sets.

We report the results of a detailed theoretical analysis of a novel, collisional mechanism of escape of molecular hydrogen and its isotopologues from martian atmosphere. The escape of H (sub 2) is induced by the elastic and inelastic collisions between the hot oxygen atoms and the thermal hydrogen molecules. To accurately describe the O + H (sub 2) (v,j) collision we have calculated elastic, inelastic, and reactive total and differential cross sections using advanced methods of the quantum scattering theory. The energy transfer rates were self-consistently determined for different translational, rotational and vibrational excited states of H (sub 2) . The distribution of the translational energy of the recoiled H (sub 2) molecules has been modeled and non-thermal rotational and vibrational distributions of the escaping H (sub 2) (v',j') molecules were constructed. To evaluate the non-thermal escape flux of H (sub 2) we used a 1D column model of martian atmosphere with realistic hot oxygen production rates and densities of atmospheric gases. We find that the non-thermal H (sub 2) escape rates, computed for different solar conditions, are comparable to Jeans escape rates, while the difference becomes more pronounced for the other isotopologues. The collisionally ejected H (sub 2) has a characteristic distribution of rovibrational states with a significant fraction of populated higher rotational states, leading to possible observational identification. The described process of molecular escape is not restricted to martian atmosphere and applicable to other molecules.

Recent crater counts on individual lava units argue for multiple phases of activity over the last 230 Myrs, with the most recent volcanic features dating to just nearly equal 2 Ma. The region also contains the youngest outflow channels on the planet. Multiple channel systems which are present across the region are interpreted to have been carved by the release of deep ground water (>1 km) from the broadly east-west trending Cerberus Fossae graben system. Elysium Planitia is therefore a region of high scientific interest, as it represents an ideal site to investigate the interaction of lava and water both below and on the surface of Mars. Extensive geologic mapping of Elysium Planitia has provided detailed information concerning the stratigraphy of the major volcanic units in addition to the classification of other landforms attributed to volcanic (e.g. small shields), fluvial (e.g. outflow channels) and aeolian (e.g. yardangs) activity. Orbital sounding radar provides a means to take this work to the next level through the mapping of buried surfaces associated with a contrast in dielectric permittivity and thus can be used to investigate the 3-D structure of the subsurface. Previous studies using the SHARAD radar sounder onboard the Mars Reconnaissance Orbiter have identified multiple subsurface reflectors below the plains of Elysium Planitia. We will present our investigation of SHARAD data covering the eastern portion of this region of Mars - an area that includes the upstream reaches of Marte Vallis and the eastern extent of Cerberus Fossae. Our subsurface mapping shows remarkable correlations with published geologic maps produced using visible orbital datasets. These similarities allow us to use SHARAD data to make estimates of the average permittivity values and imply density measurements of the volcanic units. We will present these estimates and compare them to values derived over other young volcanic regions on Mars. Sounding radar provides the only type of orbital instrument to derive bulk estimates of geochemical properties of martian volcanic materials. Additionally we have identified the original fluvial eroded bed of Marte Vallis, prior to burial by younger lava flows. Through the mapping of the associated fluvial features we are able to tie the origin of Marte Vallis to Cerberus Fossae and provide further support for the recent (Late Amazonian) deep subsurface release of water on the surface of Mars. Our work will provide valuable constraints on the influence of recent volcanism on martian subsurface reservoirs of water.

Mercury likely preserves a more complete record of early crustal formation than do Venus, Earth, or Mars, each of which experienced extensive and prolonged resurfacing and near-surface alteration since earliest crustal formation. The MErcury Surface, Space ENvironment, GEochemisty, and Ranging (MESSENGER) spacecraft was inserted into Mercury orbit on 18 March 2011 and carries a suite of instruments designed for remote sensing of elemental and mineralogical composition including a Gamma-Ray Spectrometer (GRS). We report measured surface abundances of radioactive elements on Mercury and their implications for hypotheses regarding the planet's formation and thermal evolution. The average surface abundances of radioactive elements over the region of Mercury measured by the GRS are 1150 + or - 220 ppm K, 220 + or - 60 ppb Th, and 90 + or - 20 ppb U. Ratios of the moderately volatile incompatible element K to the refractory incompatible elements Th and U provide insights into the volatile inventory of planetary bodies. The measured K/Th ratio for Mercury (5200 + or - 1800) is comparable to values for the other terrestrial planets. By contrast, the lunar K/Th value (360) is an order of magnitude lower, indicative of the depletion of lunar volatiles relative to Earth. Mercury's K/Th ratio, combined with the high abundance of the volatile element sulfur measured by the MESSENGER X-Ray Spectrometer, indicates that the planet has a volatile inventory similar to those of the other terrestrial planets. Hypotheses proposed to explain the unusually high ratio of metal to silicate on Mercury also carry predictions for the ratios of volatile to refractory elements that can be tested against the K, Th, and U abundances measured by MESSENGER. The abundance of K, relative to Th and U, is inconsistent with physical models for the formation of Mercury requiring extreme heating of the planet or its precursors and supports formation of the innermost planet from relatively volatile-enriched material comparable to known chondritic meteorites. Abundances of K, Th, and U indicate that heat production declined substantially in the past 4 Gy, consistent with widespread volcanism near the end of late heavy bombardment and only limited volcanic activity since.

The X-Ray Spectrometer (XRS) onboard is revealing the abundances of major elements in the planet's surface for the first time and is thus providing fresh information on Mercury's accretional, differentiation, impact, and geological history. X-rays that emanate from the solar corona during flares excite fluorescent X-rays with characteristic energies from the top approximately 100 mu m of Mercury's surface that are measured by XRS. Forward modelling of the resulting spectra allows elemental abundances for major-elements (Mg, Al, Si, S, Ca, Ti and Fe) to be determined. The data so far show that Mercury's bulk surface composition is distinct from those of the other terrestrial planets, with relatively high Mg/Si and low Al/Si and Ca/Si ratios that lie between those typical of basaltic and ultramafic compositions and are comparable to those for terrestrial komatiites. Derived sulfur abundances are at least ten times higher (up to approximately 4 wt %) than for the silicate portions of the Earth or Moon, whereas Ti and Fe abundances are low ( approximately 0.8 wt % and approximately 4 wt % respectively). Although the individual footprints for much of the flare data are large, there is compositional heterogeneity across the planet that can be correlated with surface reflectance and geological units. These results, together with the low Fe abundance, indicate that Mercury does not possess a feldspathic flotation crust such as that of the Moon. Rather, it suggests the surface is more likely dominated by lava flows that are products of high-degree partial melting of the mantle. The observations also support the idea that Mercury accreted from highly reduced, but not strongly volatile depleted, precursor materials similar to enstatite chondrites or anhydrous cometary dust particles. The low Fe and Ti abundances seen by XRS do not support the proposal that opaque oxides of these elements are the source of the low and variable surface reflectance of Mercury, nor can they account fully for the high neutron absorption detected during the MESSENGER flybys.

Uncertainty persisted until the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) flybys in 2008-2009 confirmed that volcanism had been widespread. Questions that remain after those flybys include the global extent of volcanic plains, their style and mode of emplacement, their temporal distribution, and their association with other geological features. MESSENGER high-resolution images of Mercury obtained from orbit are providing insight into these issues and reveal that a large contiguous area of smooth plains that exceeds approximately 6% of the surface of the planet occupies much of the high northern latitudes. Smooth surface morphology, embayment relationships, color data, candidate vents and flow fronts, and a population of partly to wholly buried (ghost) craters provide evidence for a volcanic origin for these plains and emplacement to depths in excess of a kilometer. Nearby is an unusual assemblage of 5-10 km-diameter pits, teardrop-shaped hills, rough plains, and distal lobate-margined smooth plains, interpreted to represent source vents, lava sculpting of underlying terrain, and distal emplacement of extensive flow lobes. MESSENGER X-Ray Spectrometer data of the northern plains and elsewhere provide evidence for compositions broadly similar to terrestrial komatiites. This volcanic assemblage is consistent with the rapid emplacement of high-temperature, low-viscosity komatiite-like flood lavas and the thermal erosion of subjacent terrain. The age of these plains is similar to those associated with and postdating the Caloris impact basin, confirming that volcanism was an important process in the post-heavy-bombardment era on Mercury. These extensive plains, in the context of global volcanic deposits, expand our understanding of the nature and history of volcanism on Mercury.

Impact craters that excavated material spectrally distinct from the surrounding pre-impact surface serve as windows into the subsurface, allowing observations of material at depth that would otherwise remain hidden to remote observations. Previous localized studies of spectrally distinct, excavated material suggested the presence of buried volcanic plains and a heterogeneous crustal stratigraphy and support the important role of volcanism in the evolution of the crust. MESSENGER's Mercury Dual Imaging System (MDIS) has since acquired global color (1 km/pixel) and high-resolution monochrome (250 m/pixel) base maps of the innermost planet, taken under illumination and observation geometries optimized for observing both color and morphology. These base maps, along with detailed targeted observations (up to 80 m/pixel color and 10 m/pixel monochrome), allow detailed co-mapping of geologic and spectral features across Mercury's surface. Such mapping, along with the use of scaling laws and melt-volume calculations to bound the depth of origin of crater ejecta and central peak structures, allows us to investigate many aspects of Mercury's crustal stratigraphy, including, but not limited to, the following topics: (1) The stratigraphy of four of Mercury's younger large basins: Caloris (1550 km in diameter), Rembrandt (720 km), Beethoven (630 km), and Tolstoj (360 km), which have all been flooded by spectrally distinct volcanic plains. Post-flooding craters of varying sizes enable an estimation of the thickness of the volcanic fill and the nature of the pre-flooding basin floor. These measurements will help to constrain models for subsequent compensation, uplift, and deformation; and incorporation of topography and gravity data link basin fill with the broader lithospheric evolution of Mercury. (2) The depth of origin and distribution of low-reflectance material (LRM), a likely compositional end-member. LRM centers are often associated with large crater and basin ejecta, implying that this material must originate at substantial depth. In previous studies, LRM was found to be the color unit with the greatest depth of origin. A more complete knowledge of LRM distribution in the crust will enable a better assessment of the nature of the material's pre-excavation origin. (3) The location and thickness of pre-Tolstojan (> 4.0 Ga) volcanic plains. Such plains tend to be located beneath younger intermediate plains and may be used to assess the extent of an older generation of volcanic activity.

Plains cover much of the surface, and no terrain is as heavily cratered as the lunar highlands. Plains formation appears to have occurred throughout much of Mercury's history. Intercrater plains formation extended through the period of heavy bombardment, and smooth plains formation may have continued into the second half of solar system history, with a continuum of ages in between. However, the mode of formation of these plains is not clear in all cases. Strong evidence for a volcanic origin of many plains units indicates that volcanism played an important role in shaping Mercury's crust, but many plains units lack clear evidence for source regions, flooding or embayment relationships, or color boundaries, suggesting that alternate mechanisms of formation are possible (e.g., impact-produced melt or fluidized basin ejecta). We focus on the origin of these more ambiguous plains units, particularly the intercrater plains, to understand their role in crustal formation. Preliminary maps of plains covering approximately 55% of Mercury were produced from Mariner 10 and MESSENGER flyby data. We have extended these maps with global orbital image mosaics (monochrome at 250 m/pixel; color at 1 km/pixel) and targeted high-resolution images (up to approximately 10 m/pixel). We find many regions where morphologic boundaries between plains units are gradational and no difference in spectral properties is detected. The distinction between such units appears to be largely the enhanced population of secondary craters in some locations, which destroy evidence of an original morphologic boundary or mask the original character of the unit. Many of these units also lack a clear association with any large basin, suggesting that an origin as basin ejecta is unlikely. Thus, some portion of more heavily cratered plains units may simply be degraded versions of smooth plains and share a common volcanic origin. We also explore the origin of smooth plains units contained wholly within impact craters. Impact melt production is predicted to be 14 times higher on Mercury than on the Moon, consistent with initial observations of comparatively larger melt volumes. A quantitative comparison of observed melt volumes and model predictions will help to separate plains produced by the primary cratering events from later volcanic activity in cases where morphologic evidence is ambiguous. A better understanding of the various modes of plains formation throughout Mercury's history aids in understanding the nature of Mercury's crust. The geologic and spectral evidence is consistent with a crust shaped by volcanic eruptions through time, rather than a primitive crust such as that produced by a global magma ocean.

The Mercury Dual Imaging System is acquiring global monochrome and multispectral image maps. Complementing the global maps are special targeted observations with resolutions as good as 10 m/pixel for monochrome and 80 m/pixel for multispectral images. These high-resolution morphology and color images reveal an unusual landform on Mercury, characterized by small (tens of meters to a few kilometers), fresh-appearing, irregularly shaped, shallow, rimless depressions, often occurring in clusters and in association with high-reflectance materials. The features ("hollows") are commonly found on the central peaks, floors, walls, and rims of impact craters or basins, implying a link to material brought near the surface from depth during crater formation. Hollows occur in both rayed (Kuiperian) craters as well as older degraded craters. They have been identified over a range of latitudes (approximately 54 deg. S to 66 deg. N) and at longitudes for which images with adequate spatial resolution and appropriate illumination and viewing conditions have been collected. The hollows are found in locations known from prior flyby observations to have characteristic high reflectance and a shallow slope of spectral reflectance versus wavelength relative to the global average. The most likely formation mechanisms for the hollows involve recent loss of volatiles through some combination of sublimation, sputtering, outgassing, or pyroclastic volcanism. A hollow found on the south-facing inner wall of a crater at a high northern latitude suggests a correlation with peak diurnal temperatures. The involvement of volatiles in formation mechanisms for the hollows fits with growing evidence that Mercury's interior contains higher abundances of volatile materials than predicted by most scenarios for the formation of the Solar System's innermost planet. Mercury is a small rocky-metal world whose internal geological activity was generally thought to have ended long ago. The presence of potentially recent surface modification by non-impact processes implies that Mercury's endogenic geological evolution may still be ongoing.

Two of the best-preserved peak-ring basins, Raditladi and Rachmaninoff (diameter D approximately 265 and 290 km) display predominantly circumferentially oriented graben on the floors within their peak rings. Similar graben are seen in Schrodinger basin on the Moon (D approximately 312 km), though the distribution and orientation of graben differ. This faulting style is not observed within much larger (D > 1000 km) impact basins on the Moon, where faulting is likely related to lithospheric flexure caused by subsidence of volcanic loads within the basin. In the Caloris basin on Mercury (D approximately 1500 km), extensional faulting is generally inferred to be related to uplift in response to different phases of exterior volcanic loading or lateral crustal flow. The smaller sizes of the Raditladi and Rachmaninoff basins combined with the absence of graben outside their peak rings make these mechanism unlikely to explain the observed faulting. Moreover, whereas the smooth plains inside the peak ring of Rachmaninoff basin appear to be volcanic in nature, the plains within Raditladi basin are not resolvably younger than the basin and may consist of solidified impact melt. Thus, any mechanism proposed to explain the origin of graben in these basins must apply to either floor material. Here we use thermo-mechanical finite element models to calculate the stress states resulting from several candidate mechanisms for graben formation. Models of subsidence associated with the emplacement of interior fill as well as those of uplift associated with undercompensated basin topography do not lead to the required stress state. We also explore the idea that porous breccias beneath the smooth plains are heated by impact melt or volcanic fill and undergo viscous compaction, causing subsidence of the fill material. In combination with interior filling by plains that thin outward, this mechanism can produce the required stress state, but resulting differential stresses are too small to induce the observed fault slip. Extension driven by cooling and contraction of an outwardly thinning fill can induce the correct stress state with differential stress magnitudes > 5 GPa, sufficient to induce hundreds of meters of fault slip in agreement with observed strains. This fill geometry is consistent with hydrocode models of peak-ring basin formation that yield thicker impact melt in the basin center. If the basin fill is instead volcanic and emplaced in several phases, a radial thinning of each new layer can result from subsidence of the basin center as a result of cooling or loading.

Most of the volcanic deposits on Mercury are similar in morphology to lunar mare flood basalt deposits and are found on Mercury in smooth plains regions such as in the extensive northern smooth plains. Adjacent to the northern smooth plains is an unusual assemblage of 5-10-km-diameter pits, teardrop-shaped hills, rough plains, and distal lobate-margined smooth plains; these features are interpreted to represent source vents, lava sculpting of underlying terrain, and distal emplacement of extensive flow lobes. These features are consistent with eruption of high-temperature, low-viscosity komatiite-like flood lavas that erode and sculpt the underlying terrain during flow on Mercury. Evidence of this process is observed extensively on other terrestrial planets where eroded channels are often seen in association with source depressions. Here we analyze Mercury Laser Altimeter (MLA) data and MDIS images to document morphologic and morphometric constraints on the amount of erosion that occurred and the amount of lava that was emplaced during the formation of this scoured surface. These constraints are used as inputs into models of mechanical and thermal erosion to determine which erosion regime, mechanical or thermal, was dominant during the formation of this terrain, as well as to determine plausible erosion rates and eruption durations required to form the observed scoured terrain. We compare processes of volcanism and thermal/mechanical erosion on Mercury with similar processes on Earth, the Moon, Mars and Venus.

Many of Mercury's smooth plains, including a broad expanse of such plains at high northern latitudes well imaged for the first time, show evidence for a volcanic origin. Using orbital images from MESSENGER's Mercury Dual Imaging System (MDIS), we have identified a set of flow features proximal to these northern smooth plains deposits that provide a framework for understanding how smooth plains are emplaced across Mercury. Here, several channels cut through intercrater plains material, and strongly resemble channelized surface flow landforms on Earth and Mars. The channels exhibit the braided textures, deltas, and elongate, teardrop-shaped "islands" characteristic of erosion by the above-ground movement of a low-viscosity liquid -- consistent with high-temperature lavas with komatiite-like compositions reported by MESSENGER's X-Ray Spectrometer (XRS) team. One channel links a set of candidate volcanic vents with a peak-ring basin that hosts smooth plains deposits, possibly representing a complete extrusive system from eruption to emplacement. Additionally, the surrounding intercrater plains display a range of topographic expressions, from rough to almost entirely smooth, implying flooding to various depths by lavas. These observations suggest that Mercury's smooth plains were emplaced, at least in part, by many discrete, low-viscosity, komatiite-like lavas that reshaped the surface over which they flowed. We use the linear textures in the channels to determine flow directions and to place constraints on the local paleotopography, and by mapping the area of flooded terrain in a geographical information system (GIS), we give a minimum value for the amount of material erupted in this region. Together with topographic profiles obtained from the Mercury Laser Altimeter (MLA), we provide possible effusion and flow rates within these channels for a range of lava viscosities, yielding an estimate for the time taken to form these northern deposits. The flooded textures seen adjacent to the northern smooth plains are replicated elsewhere on Mercury, and a search for other examples of flow channels now underway will act as a basis to extend our analysis of flow characteristics near these northern smooth plains to other areas, and eras, on Mercury.

These images support the conclusion that internal geological activity on Mercury did not end early in planetary history, as had generally been previously thought, but continued to geologically recent times. Three lines of evidence point to recent geological activity on Mercury. (1) There are smooth plains with surface areas up to 1.5X105 km (super 2) that postdate young (morphological class 1) craters, indicating probable Kuiperian-aged volcanism. No volcanic vents, fissures, or flow fronts have been identified on these plains, suggesting that they are products of low-viscosity lavas, consistent with komatiite-like compositions of large areas on Mercury indicated by MESSENGER X-Ray Spectrometer observations. (2) Young lobate scarps transect class 1 craters as large as 30 km in diameter, indicating comparably recent crustal contraction. (3) A number of fresh-appearing, high-reflectance, irregularly shaped and rimless shallow depressions interpreted as pyroclastic vents have few superposed craters, suggesting that they have been recently active. Growing evidence from geological and geochemical observations indicates that Mercury's interior contains a higher abundance of volatile materials than was previously appreciated. Together these findings support the inference that Mercury experienced relatively recent volcanism and tectonic deformation, and the possibility that the planet is geologically active today cannot be discounted.

Lobate scarps are linear to arcuate structures that are tens to hundreds of kilometers long, have topographic relief of hundreds of meters to kilometers, and are interpreted as the surface expression of major thrust faults. Flybys of Mercury by the MESSENGER spacecraft confirmed that lobate scarps are the dominant tectonic feature over nearly the entire planet. Ranging to the surface by the Mercury Laser Altimeter (MLA) since MESSENGER's orbit insertion on March 18, 2011, has yielded hundreds of topographic profiles, largely over Mercury's northern hemisphere. We utilize MLA measurements of lobate scarp topography to constrain fault models and mechanical properties of Mercury's lithosphere. Mean along-track resolution of the MLA data is approximately 300 m, but cross-track spacing varies with latitude, so we currently confine our analyses to individual profiles. Overlaying MLA profiles on images taken by the Mercury Dual Imaging System (MDIS) allows the relief and morphology of lobate surface scarps in Mercury's northern hemisphere to be characterized. Many of these features display the expected signature for lithospheric flexure in response to bending moments applied at underlying thrust faults. We model these faults and their accompanying flexure by means of a mechanical model of the lithosphere that includes an elastic plate overlying an inviscid substrate to accommodate buoyancy forces. Model parameters that are varied are the geometry of the fault and the thickness of the effective elastic lithosphere. Long-wavelength pre-scarp topography is estimated by first de-trending the profiles. We estimate the thickness of the mechanical lithosphere via the relationship between bending moment and plate curvature given a yield strength envelope for Mercury's lithosphere. Comparison of model profiles to the MLA profiles over lobate scarps provides information on the local mechanical thickness of the lithosphere in the northern hemisphere of Mercury.

Among these, lobate scarps were seen as the dominant features and have been interpreted as having formed as a result of global contraction in response to interior cooling. Extensional troughs and graben, where identified, were generally confined to intermediate- to large-scale impact basins. However, the true global spatial distribution of tectonic landforms remained poorly defined because the flyby observations were limited in coverage and spatial resolution, and many flyby images were obtained under lighting geometries far from ideal for the detection and identification of morphologic features. With the successful insertion of MESSENGER into orbit in March 2011, we are exploiting the opportunity to characterize the tectonics of Mercury in unprecedented detail using images at high resolution and optimum lighting, together with topographic data obtained from Mercury Laser Altimeter (MLA) profiles and stereo imaging. We are digitizing all of Mercury's major tectonic landforms in a standard geographic information system format from controlled global monochrome mosaics (mean resolution 250 m/px), complemented by high-resolution targeted images (up to approximately 10m/px), obtained by the Mercury Dual Imaging System (MDIS) cameras. On the basis of an explicit set of diagnostic criteria, we are mapping wrinkle ridges, high-relief ridges, lobate scarps, and extensional troughs and graben in separate shapefiles and cataloguing the segment endpoint positions, length, and orientation for each landform. The versatility of digital mapping facilitates the merging of this tectonic information with other MESSENGER-derived map products, e.g., volcanic units, surface color, geochemical variations, topography, and gravity. Results of this mapping work to date include the identification of extensional features in the northern plains and elsewhere on Mercury in the form of troughs, which commonly form polygonal patterns, in some two dozen volcanically flooded impact craters and basins.

The collection houses 160,680 physical rock and ore specimen lots ("samples"), all of which already have a digital record that can be accessed by the public through a searchable web interface (http://collections.mnh.si.edu/search/ms/). In addition, there are 66 accessions pending that when catalogued will add approximately 60,000 specimen lots. NMNH's collections are digitally managed on the KE EMu(Registered) platform which has emerged as the premier system for managing collections in natural history museums worldwide. In 2010 the Smithsonian released an ambitious 5 year Digitization Strategic Plan. In Mineral Sciences, new digitization efforts in the next five years will focus on integrating various digital resources for volcanic specimens. EMu sample records will link to the corresponding records for physical eruption information housed within the database of Smithsonian's Global Volcanism Program (GVP). Linkages are also planned between our digital records and geochemical databases (like EarthChem or PetDB) maintained by third parties. We anticipate that these linkages will increase the use of NMNH collections as well as engender new scholarly directions for research. Another large project the museum is currently undertaking involves the integration of the functionality of in-house designed Transaction Management software with the EMu database. This will allow access to the details (borrower, quantity, date, and purpose) of all loans of a given specimen through its catalog record. We hope this will enable cross-referencing and fertilization of research ideas while avoiding duplicate efforts. While these digitization efforts are critical, we propose that the greatest challenge to sample curation is not posed by digitization and that a global sample registry alone will not ensure that samples are available for reuse. We suggest instead that the ability of the Earth science community to identify and preserve important collections and make them available for future study is limited by personnel and space resources from the level of the individual PI to the level of national facilities. Moreover, when it comes to specimen "estate planning," the cultural attitudes of scientists, institutions, and funding agencies are often inadequate to provide for long-term specimen curation - even if specimen discovery is enabled by digital registry. Timely access to curated samples requires that adequate resources be devoted to the physical care of specimens (facilities) and to the personnel costs associated with curation--from the conservation, storage, and inventory management of specimens, to the dispersal of samples for research, education, and exhibition.

Inferring paleovegetation from fossils has turned out to be very difficult, however, and today most paleobotanical methods for inferring paleoclimate do not try to reconstruct paleovegetation as a first step. Three major approaches are widely use to infer paleoclimate from plant fossils: 1) phylogenetic inferences rely on the climatic distributions of extant relatives of fossils, 2) morphological inferences use present-day correlations of climate with plant morphology (e.g, leaf shape, wood anatomy), and 3) chemical inferences rely on correlations between climate and the stable isotopic composition of plants or organic compounds. Each approach makes assumptions that are hard to verify. Phylogenetic inference depends on accurate identification of fossils, and also assumes that evolution and/or extinction has not shifted the climatic distributions of plant lineages through time. On average this assumption is less valid for older time periods, but probably it is not radically wrong for the early Cenozoic. Morphological approaches don't require taxonomic identification of plant fossils, but do assume that correlations between plant form and climate have been constant over time. This assumption is bolstered if the ecophysiological cause of the morphology-climate correlation is well understood, but often it isn't. Stable isotopic approaches assume that present-day correlations between isotopic composition and climate apply to the past. Commonly the chemical and physiological mechanisms responsible for the correlation are moderately well known, but often the variation among different taxonomic and functional groups of plants is poorly characterized. In spite of limitations and uncertainties on all methods for inferring paleoclimate from fossil plants, broad patterns emerge from analysis of early Cenozoic floras from the Rocky Mountain region. Paleocene climates across the region were warm with warm winters. Mean annual temperature estimates vary from 10-18 degrees C depending on the time and place, and ground-freezing climates occurred only north of 40-45 degrees N. Plants and sedimentary environments suggest low altitude deposition, though floras are not as homogeneous as once thought, suggesting barriers existed. Eocene climates were warmer, with mean annual temperature estimates of 14-25 degrees C, and ground-freezing climates occurring only north of the Canadian border. Paleobotanical evidence for substantial paleoelevations in basinal areas is weak, but volcanic terrains to the west preserve floras that suggest higher paleoelevations, even in the early and middle Eocene. The terms "frost-free" and "tropical" have sometimes been used to describe Eocene climate and vegetation of the northern U.S. Rocky Mountains, but are probably not justified, with the possible exception of the the warmest early Eocene hyperthermal events at low paleoelevation.

For this reason, energetic understanding of Earth's interior requires knowledge of the thermal conductivity of the core. We have measured the electrical resistivity of iron and iron-silicon alloy at high pressures in the diamond anvil cell using a four probe method (van der Pauw); thermal conductivity is proportional to the electrical resistivity via the Wiedemann-Franz law. We present a new model which describes the pressure and temperature dependence of the thermal conductivity of iron and iron-silicon alloys. The data and model predict that the thermal conductivity of Earth's core is significantly higher than previously suggested; implying enhanced conductive heat transport in the core. When the conducted heat flux within the core is compared to reasonable assumptions of the core mantle boundary heat flux-the total heat escaping the core, one concludes that a thermally stratified layer is likely to develop at the top of the outer core. If this thermally stratified layer is stable over geologic time, chemical gradients may develop at the boundary of the stratification due to changes in the bulk composition of the fluid outer core associated with chemical fractionation during inner core growth. This thermo-chemical stratification provides a possible explanation for recent seismic observations of slow wave speeds in the top nearly equal 300 km of the outer core.

Changes of bulk rock chemistry, mineral assemblages and compositions, as well as microstructures operate in concert both before and during subduction to transmorgify ocean floor basalt into subduction zone eclogite. We present textural and chemical characterizations of suites of blueschists and eclogites from three subduction complexes to evaluate the extent of interactions of these processes and determine the degree to which consequences of chemical and physical features along a complex P-T-t-D may be preserved. Samples of coronitic and mylonitic eclogite and blueschist from subduction complexes in the Franciscan (CA, U.S.A.), Monviso (Western Alps) and Gruppo di Voltri (Ligurian Alps) were analyzed for major and trace elements of both rocks and minerals. Comparisons of these areas can illustrate different depths of subduction, and degrees of metamorphism. In addition, all of these suites show some degree of retrogression to blueschist or greenchist assemblages. Textural observations suggest that some primary magmatic mineral domains in gabbroic rocks are preserved through subduction, metamorphism and exhumation (e.g., Omp replacement of domains that were originally Pl). In effect some blocks in subduction complexes show evidence for multiple metamorphic episodes that transform seafloor metamorphic rocks to HP ones. In finer-grained rocks, primary domains have been totally obscured by full recrystallization and/or deformation. Trace element distributions within minerals testify to which minerals equilibrated with each other, and/or with exotic fluids. Minerals may acquire trace element signatures from precursor minerals, which themselves equilibrated with an earlier fluid, or with the bulk rock following mass transfer on a large scale. For example, the trace element chemistry of talc inclusions in omphacite within gabbroic FeTi-rich eclogites from Monviso indicates interaction of mantle-derived fluid with ocean floor Fe-Ti gabbro, preserved through subduction, eclogite facies metamorphism and exhumation. The mineral and trace element chemistry of phengite indicates that the trace element signature of this mineral is entirely controlled by exotic components in fluids that interacted with their host rocks, and not by deformation or bulk chemistry. The REE in eclogite from the Alpine Monviso and Voltri Massifs, the Franciscan Complex, and the Catalina Schist garnet amphibolites reside primarily in apatite, epidote-group minerals, garnet and titanite. The relative stabilities of the accessory minerals apatite and titanite, along with epidote, and titanite, which in some instances appear to be controlled by relative solubilities of Ca-rich silicate or phosphate minerals in aqueous solutions and brines, provide critical evidence for understanding how L- and MREE are retained, lost, or introduced during eclogite-fluid interaction upon retrogression.

Electron microprobe analyses of more than 60 high-MgO tears, which are 1-3 mm in diameter, show that most contain 11 to 12 wt. % MgO with a few approaching 13% MgO. Separate microprobe analyses for sulfur and chlorine of 20 grains revealed no appreciable amounts of either, indicating the magma was largely degassed. Polished-section studies employing an analytical scanning electron microscope show most tears are composed of pure microvesicular glass with scattered skeletal olivine crystals and rare chromite. The abundance of skeletal olivine appears to increase with decreasing MgO content of the glass. These tears contain among the highest known MgO values of any material erupted subaerially from Kilauea. The high-MgO tears occur in a 1-6 cm thick layer of medium-coarse lithic-crystal-vitric ash. The top of this layer consists of 2-3 mm of very fine lithic-crystal ash. The lithics and many of the olivine crystals in this layer are highly oxidized. This deposit is at the top of a sequence of several lithic beds that are interspersed with thinner vitric units totaling about 75 cm in thickness. It is overlain by 9-13 cm of medium pumice lapilli and coarse vitric ash at the top of the "Bluff base" and "mid-Bluff" tephra sections described by Fiske et al. (2009). This high-MgO glass layer has been found thus far in only one other locality, a 2 m-deep soils study pit within Kipuka Puaulu, 3.5 km northwest of the caldera. Based upon stratigraphic relationships and preliminary microprobe data, a few other likely exposures of the high-MgO deposit have been identified north and west of the caldera. The high-MgO vitric ash in the upper Kulanaokuaiki Tephra has a primitive composition that suggests little if any shallow level storage of magma. Instead, the magma probably rose rapidly from deep within, or below, the volcano just before its eruption. Remnants of the Kulanaokuaiki-3 scoria deposit, a subunit of the upper Kulanaokuaiki Tephra, are preserved over wide areas 7-12 km south and southeast of the summit and have characteristics also suggesting rapid rise and eruption (Fiske et al., this meeting). Some relatively primitive vitric ash occurs in the younger Keanakako'i Tephra (Garcia et al., this meeting) and can be interpreted to indicate little if any shallow storage. Thus the high-MgO glass reported here may be an end member in a family of relatively primitive compositions that can erupt under some circumstances at Kilauea's summit. Most recent tephra deposits at and near Kilauea's summit are attributed to phreatic or phreatomagmatic explosive eruptions that originated at relatively shallow depth. One important implication of our findings is that some highly energetic pyroclastic eruptions at Kilauea likely originated at far greater depths.

The experiments were designed to evaluate the effects of topography and bed roughness on current runout, buoyancy reversal and liftoff, and mass partitioning into buoyant plumes. The densimetric and thermal Richardson, Froude, Stokes, and settling numbers for our experiments match those of PDCs and the laboratory currents are fully turbulent, although the experiments have lower Reynolds numbers than PDCs, thus our experiments are dynamically similar to natural currents. Comparisons of currents traversing flat topography or encountering barriers shows that runout distance is not significantly reduced for currents that traverse barriers with height less than 1.5 times the current thickness, but currents do not pass taller barriers. Buoyancy reversals occur in most currents, resulting in liftoff and generation of a buoyant plume. Liftoff occurs near the maximum runout distance for currents traveling over flat topography, but is focused near or above barriers for currents that encounter barriers. Notably, plume formation above barriers can result in reversal of flow direction downstream of the obstruction as portions of the current flow back and feed the rising plume. Greater than half of the initial particle mass composing the density currents usually partitions into the buoyant plumes; that fraction is greater for currents that liftoff closer to the source, thus topographic barriers increase mass partitioning from currents into buoyant plumes.

These recurring patterns, found throughout the thin (6 to 25 cm thick) unit of the widespread deposit produced by the highly explosive eruption (Fiske et al. 2009), include increases and decreases in MgO (varying between >7 and nearly equal 14 wt%) as well as in compatible (Ni, Cr, Co) and incompatible (e.g., Nb and Y) elements. Accompanying these changes are subtle shifts in olivine composition (approximately Fo >78 to 82) and abundance, as shown by microprobe analyses of >200 specimens and preliminary point counts. This tephra section, which is the third of five stratigraphic units in the deposit, is interpreted as representing an inverted magma reservoir, consistent with its mineralogical assemblages, with density measurements and with abundances of lithic clasts. Comparisons between XRF analyses of larger (4-8 mm) and smaller (1-2 mm) scoria clasts indicate that the unit has retained its magmatic profile, essentially free from physical effects of post-eruption sedimentary and transport processes. In the earlier studies of Hawaiian lava lakes, MgO has been shown to decrease from the top to a minimum concentration at a relatively shallow depth and then to increase toward a maximum concentration with further increases in depth. This pattern has been associated, in part, with evidence for settling by olivine phenocrysts to yield an olivine-depleted upper region and an olivine-enriched lower region. A similar pattern is evident in the Kulanaokuaiki Tephra unit, which also displays an inflection point above which MgO decreases and below which it increases markedly with depth (when interpreted as representing an inverted magma reservoir). Preliminary data indicate, further, that this pattern may be attributable, in part, to shifts in olivine abundance. In addition to these broad similarities, the tephra unit displays several other features resembling those in lava lakes. For example, vitric pumice and interstitial glass from the tephra deposit show relatively low MgO (>5 to 53 wt%). These values are similar to those of segregation veins in lava lakes (e.g., 4.5 to 6 wt% MgO and nearly equal 51 to >53 wt% SiO (sub 2) at Kilauea Iki [Helz 1980]). Several unusually olivine-rich specimens, consisting of dense juvenile material within breccias, also have been found in the tephra unit, suggestive of olivine-rich bodies or masses observed in the lava lakes. The chemical and mineralogical similarities between the Kulanaokuaiki Tephra deposit and the lava lakes, along with these other features, suggest that a model derived from extensive research (e.g., Wright & Helz 1987) into passively cooling lava lakes, long regarded as natural laboratories, may provide insights into active volcanic systems, including those from sources deep within Kilauea's edifice.

Using regional Coulomb stress change, we evaluate to what extent slip on faults during the Mineral, VA, earthquake and its aftershocks may have increased stress on notable Cenozoic fault systems in the DC metropolitan area: the central Virginia seismic zone, the DC fault zone, and the Stafford fault system. Our Coulomb stress maps indicate that the transfer of stress from the Mineral, VA, mainshock was at least 500 times greater than that produced from the magnitude 3.4 Germantown, MD, earthquake that occurred northwest of DC on July 16, 2010. Overall, the Mineral, VA, earthquake appears to have loaded faults of optimum orientation in the DC metropolitan region, bringing them closer to failure. The distribution of aftershocks of the Mineral, VA, earthquake will be compared with Coulomb stress change maps. We further characterize the Mineral, VA, earthquake by comparing its aftershock decay rate with that of blind thrust earthquakes with similar magnitude, focal mechanism, and depth from a variety of tectonic settings. In particular, we compare aftershock decay relations of the Mineral, VA, earthquake with two well studied California reverse faulting events, the August 4, 1985 Kettleman Hills (Mw = 6.1) and October 1, 1987 Whittier Narrow (Mw = 5.9) earthquakes. Through these relations we test the hypothesis that aftershock duration is inversely proportional to fault stressing rate, suggesting that aftershocks in active tectonic margins may last only a few years while aftershocks in intraplate regions could endure for decades to a century.

One is the scarpward retreat of bright layers of the north polar basal unit (BU, immediately underlying the North Polar layered deposits, NPLD) and the overlying NPLD by fracture-controlled and undercutting-assisted piecewise failure of layer edges, resulting in rockfalls and rockslides, called blockfalls here. This is important as it suggests an alternative, significant mode of erosion in addition to sublimation which is traditionally held account-able for erosion of polar surfaces. The other form, caught in-action during imaging, comprises falls and avalanches of frost and dust over a few steep NPLD scarps during early spring. Here we report the latest findings in both of these dramatic and currently active processes and assess their role in the evolution and history of polar deposits. NPLD and BU mass wasting: Typical evidence of recent blockfall activity is in the form of blocks, flows, and debris on BU slopes. In a few cases, the appearance of new blocks in subsequent images proves this process is ongoing. In general, [likely] active outcrops have a higher overall MOLA-derived slope than [likely] quiescent outcrops (those with a lack of debris and abundance of sand on the BU). Furthermore, none of the NPLD peripheral scarps without BU exposure have slopes above 40 degrees . This suggests BU exposure and this type of mass wasting play a role in maintaining and possibly creating over-steepened NPLD scarps (often 45 degrees -65 degrees , with sections approaching vertical). The lower-sloped NPLD scarps with no BU present also do not display the severe fracturing that characterizes steep NPLD cliffs directly above BU exposures. This may be due to fracture propagation from undercutting by the BU, thermal stresses induced by rapid and intense heating on steepened slopes with high solar incidence angles, or rapid uncovering of ice that was under compressive stresses. Feedback mechanisms between these mechanisms, steepness, fracturing, and BU erosion likely exist. CO2 frost-dust falls and avalanches: In Mars Year 29, 9 of these events were observed at Ls 27 degrees -39 degrees , all at one scarp. In Mars Year 30, 27 events were observed, ceasing by Ls 50 degrees , several at additional scarps between 90 degrees -270 degrees E. All scarps are steep, >40 degrees , and exhibit fractured NPLD. Events appear to originate on the scarp face. Loosely coincident timing with regional CO2 frost sublimation suggests a causal relationship. Thermal modeling suggests CO2 may be expected to disappear from steep sections of an idealized scarp before cessation of this activity. Observational constraints on CO2 presence are provided by seasonal hyperspectral CRISM data. The fractured scarps are far from smooth, with ubiquitous crevasses and recesses, providing the potential for CO2 to persist later into the spring. As of yet, no missing NPLD blocks on the scarp face or new blocks below in subsequent images have been unequivocally attributed to these events. One observation suggests that a passing avalanche cloud can disrupt blocks of BU bright layers, which would tend to accelerate the type of blockfall mass-wasting discussed above.

Primitive basalts are petrologic indicators of the conditions of mantle melting, and Fe is particularly important because its behavior and abundance in basalt are highly sensitive to P and T of mantle melting. Yet, Fe is also uniquely sensitive to the fO (sub 2) of the mantle source, which controls the relative abundances of the two major species of Fe in the upper mantle (Fe (super 2+) , Fe (super 3+) ). Because Fe (super 2+) is the more sensitive geothermometer, constraining Fe speciation in basalts is key to accurately interpreting Fe as a sensor of magmatic and mantle conditions. Here, we present new constraints on the Fe (super 3+) /Sigma Fe ratios (i.e., Fe (super 3+) /[Fe (super 2+) +Fe (super 3+) ]) of basalts from ridges, arcs, and hot spots, determined using mu -XANES analysis of glasses and melt inclusions, and assess how fO (sub 2) influences the use of basalt Fe content to interpret P-T conditions of magmas and melting. Using ol-liquid or ol-opx-liquid thermometry (Putirka, 2007; Lee et al., 2010), modeled basalt temperatures decrease by nearly equal 0.4-0.6 degrees C, and equilibration temperatures of basalt with the mantle decrease by nearly equal 4.4 degrees C, for every 1% increase in Fe (super 3+) /Sigma Fe ratio of the melt. Global mid-ocean ridge basalts (MORB) have a narrow range of Fe (super 3+) /Sigma Fe (0.13-0.17; Cottrell & Kelley, 2011), significantly higher than prior bulk analyses have shown (0.07-0.12; Christie et al., 1986; Bezos & Humler, 2005). This upward revision has a small impact on modeled magmatic temperatures (max. Delta T of -4 to -6 degrees C), but it significantly impacts the modeled temperature of the MORB mantle source (max. Delta T of -44 degrees C), shallowing the base of the melting triangle by nearly equal 15 km. This decrease in potential temperature may be overshadowed, however, by the impact of fO (sub 2) on the depth of the graphite-CO (sub 2) transition. Reduced C has low solubility in silicate melts, but oxidized C will act as a flux (Dasgupta and Hirschmann, 2006). The upward revision of the MORB source fO (sub 2) may therefore expand the melt triangle by expanding the field of carbonatitic silicate melts (Dasgupta & Hirschmann, 2010). At arcs, both high dissolved H (sub 2) O contents and high Fe (super 3+) /Sigma Fe ratios (0.18 to 0.30, globally) in basalts impact thermobarometric models used to constrain mantle source conditions. An arc basalt with 6 wt.% H (sub 2) O and Fe (super 3+) /Sigma Fe=0.30 is nearly equal 80 degrees C cooler than the same basalt with 2 wt.% H (sub 2) O and Fe (super 3+) /Sigma Fe=0.20, although only nearly equal 5 degrees C of this difference is attributed to Fe speciation. At conditions of the arc mantle source, higher H (sub 2) O contents and Fe (super 3+) /Sigma Fe ratios of basalts indicate ambient mantle temperatures ranging from MORB-like to nearly equal 100 degrees C cooler than the MORB source. Despite lower temperatures, however, melting beneath arcs may occur at higher pressures due to the inverted geothermal gradient and H (sub 2) O input flux in the lower half of the mantle wedge beneath arc volcanoes. For ocean island basalts (OIB), Fe (super 3+) /Sigma Fe ratios vary from MORB-like to relatively oxidized (0.14-0.25). Although OIBs may have both elevated Fe (super 3+) /Sigma Fe ratios and higher dissolved H (sub 2) O relative to MORB, higher total Fe concentrations than average MORB offset the effects of H (sub 2) O and Fe (super 3+) on modeled mantle temperatures. Mantle temperature beneath Samoa is modeled at nearly equal 150 degrees C in excess of the average MORB source.

To address this question, we compiled and calendar-calibrated 83 (super 14) C ages (all that we could find, published and unpublished) for lava flows erupted during the past 2500 years. The results show that effusive activity takes place dominantly in episodes lasting several centuries separated by long periods of greatly reduced extrusive frequency. Coinciding with these downturns are periods of episodic explosive eruptions from a summit caldera. Lava flows occurred for at least 200 years before ca. 300 BCE. A period of episodic explosive eruptions lasted from 300 BCE to ca. 1000 CE. Lava flows were again dominant in 1000-1500 CE. Episodic explosive activity occurred over the next ca. 300 years (1500-1800 CE), and lava flows have prevailed since 1800. In the past 2500 years, effusive activity dominated 40 percent of the time and episodic explosive activity 60 percent. These results have important ramifications. Most explosive eruptions at Kilauea are phreatomagmatic or phreatic and are thought to be generated at or below the water table, today about 615 m below the rim of the caldera and 450-500 m below the caldera floor. If true, the data indicate periods of time lasting centuries during which the caldera was frequently if not continuously deep (at or below the water table). The presence of a deep caldera apparently inhibits extrusion on the flank of the volcano, perhaps because caldera collapse destroys the magma reservoir that feeds magma into the rift zones. It may take centuries for this reservoir to reestablish itself. In the meantime, magma rising from the mantle (probably at a supply rate reduced from that during effusive periods) may not stall in a shallow reservoir. Relatively primitive magma can therefore appear at the surface in explosive eruptions, little changed by residence or mixing with magma in a shallow reservoir. This hypothesis is supported by recent microprobe analyses of vitric ash, which have found relatively primitive compositions in the 1500-1800 CE period (Keanakako'i Tephra; 10.5- nearly equal 11 percent MgO) and the 300 BCE-1000 CE period (Uwekahuna Tephra, specifically the Kulanaokuaiki Member; MgO nearly equal 13 percent); such high-MgO glass compositions have rarely if ever been reported elsewhere on subaerial Kilauea. The periods of dominantly extrusive activity build the edifice. Every few hundred years, edifice-building slows or stops when a deep caldera forms in response to draining of the summit reservoir during a large eruption, a large extensional event along the east rift zone coupled to south-flank movement, or some other cause. It then takes a few hundred years for the caldera to again develop an integrated reservoir system; once that is complete and the system is pressurized, magma can inject into the rift zones and erupt on the flanks as well as at the summit. We have no way to judge Kilauea's earlier activity but see no reason that it should have been different, at least back to the Pleistocene. This conceptual model builds on one developed in 1987 by Robin Holcomb in USGS Professional Paper 1350, and we propose calling the alternating styles of activity the Holcomb cycle.

K-3 tephra consists of two main components: dense lithic clasts and a thin layer of basalt scoria that hosts these clasts. The lithic clasts consist of a wide variety of lava-flow lithologies, of which nearly equal 20 % are fine-coarse gabbro, some containing interstitial glass. The most accessible K-3 lithics occur as lag clasts on the south flank, where the host scoria has been eroded away. These clasts are widely scattered, and a person not purposely searching for them would probably overlook them. Using a sampling grid 700 m on a side containing 110 collecting sites, we found that clast diameters decrease regularly toward the SSE; grapefruit-size clasts occur near Kulanaokuaiki Pali (7-8 km SE of the summit) and "golf-ball rocks" are widely scattered along the south coast of the island (17 km distant). K-3 scoria, 2-12 cm thick, hosts the lithic clasts and is massive at most south-flank sites. In places, however, it consists of two distinct subunits separated by a thin layer of medium ash. Whole-rock XRF analyses of cm-by-cm "slices" through the deposit permit the identification of the two subunits in places where the separating ash layer is absent. MgO values in the upper subunit increase regularly upward from nearly equal 8 wt % to a maximum of nearly equal 14 wt % over an area of 60-70 sq km, an upside-down compositional pattern suggesting a zoned magma body. Collectively, the following relations suggest the K-3 eruption was a diatreme-like event. (1) An unusually energetic eruption is required to explain the far-traveled lithic clasts. (2) The volume of the lower and upper K-3 subunits (about 7 million and 13 million cubic meters, respectively) correspond to eruptions having VEI values in the mid 2s to lowermost 3s. "Normal" VEI-2 to -3 eruptions would be incapable of propelling the large and dense lithic clasts for the distances observed. (3) Proximal Kulanaokuaiki Tephra in Uwekahuna Bluff, of uncertain relation to K-3 further south, contains fresh glass having MgO compositions approaching 13 wt % (see related poster by Rose et al., this meeting), suggesting primitive magma involvement in at least part of the Tephra. (4) A small piece of marine limestone containing possible deep-water sponge spicules was discovered in a reworked K-3 section in a remote area at an elevation of 900 m. We suggest the driver for the K-3 eruption was a diatreme-like release of CO (sub 2) , reaming a conduit that intersected a wide variety of sub-summit rock bodies and two or more magma bodies on its way to the surface. This powerful and sustained CO (sub 2) release swept lithic clasts and scoria to heights of >10 km, where prevailing northwest jet-stream winds deflected their rise and fall to the southeast.

Eleven samples along a 30 cm traverse of an amphibolite grade block and its reaction rind adjacent to ultramafic-rich matrix, show dramatic change in mineral abundance and whole-rock major and trace element and Li isotope composition. Samples of the rind are enriched in whole-rock SiO (sub 2) , K (sub 2) O, Rb, Ba, Li, MgO, Cr, Ni, and also Os, Ir and Ru relative to samples of the block core, and are depleted in FeO, Al (sub 2) O (sub 3) , TiO (sub 2) , CaO, and Zr. delta (super 7) Li (sub L-SVEC) ranges from -3 to +1ppm and the distribution of Li concentrations and delta (super 7) Li is consistent with diffusion on the scale of nearly the entire profile. FeO content of garnets in the rind is lower than that of garnets in the block core, reflecting whole-rock FeO concentrations, and suggesting garnet growth after the depletion in whole-rock FeO. Garnets in the rind show extensive pseudomorphing by decussate chlorite, suggesting post-garnet growth infiltration by H (sub 2) O-rich fluid. Rind concentrations of Cr, Ni, Zr, Al (sub 2) O (sub 3) , TiO (sub 2) , FeO, and possibly CaO, MgO, Na (sub 2) O, and Sr can be most simply explained by mechanical mixing of mafic block with melange matrix. Such mixing cannot explain the increases in SiO (sub 2) , K (sub 2) O, Li, and Ba, and we propose that the concentrations of these elements in the rind reflect element mobility during relatively late-stage fluid infiltration. We propose an early episode of mechanical mixing during which mixing of material derived from the mafic block and melange matrix produced rind-like material which then accreted onto the basaltic block. Garnet growth in both the block core and the rind occurred after this mechanical mixing. Fluid infiltration in the rind occurred after peak metamorphism of the block, causing alteration of garnet to chlorite and the growth of white micas at the rims of amphiboles in the block rind. This fluid was likely sourced in devolatilizing metasedimentary rocks within the subduction zone, as has been proposed based on O isotope compositions of this amphibolite-facies melange unit.

However, in contrast to salt marsh-based studies, there are fewer studies using mangrove foraminifera to reconstruct former sea level despite the importance of far field tropical localities for inferring the ice-equivalent component to relative sea-level change. This study compares the performance of salt marsh and mangrove foraminifera as sea-level indicators and attempts to reconstruct relative sea-level (RSL) change at decimeter scale using mangrove foraminifera. We chose one salt marsh site (St. Marys) and one mangrove site (Hobe Sound) along the Atlantic coast of Florida with similar climatic, biological, and geological conditions. At each site we collected modern (88 samples from 6 transects) and fossil (salt marsh and mangrove peat cores) material. We found differences between these environments with regards to the abundance, composition and diversity of the foraminiferal assemblages. The most abundant species in the salt marsh are Ammobaculites spp., Ammoastuta inepta, Haplophragmoides spp., and Trochammina inflata, while the dominant mangrove species are Arenoparrelle mexicana, Ammodiscoides spp., Glomospira spp., and Haplophragmoides spp. We quantified the optimum and tolerance of each foraminiferal species to elevations relative to tidal frame and subsequently developed salt marsh and mangrove transfer functions (TF). The TFs estimate vertical uncertainty of approximately + or - 0.2 m, indicating that precise reconstructions of RSL are possible. The fossil mangrove core is dominated by species similar to the modern assemblages. We applied the mangrove-based TF and combined this with a preliminary chronology based on (super 210) Pb and (super 14) C dates to reconstruct RSL, which was validated against regional tide-gauge records, demonstrating its usefulness in assessing sea level changes in tropical to semi-tropical locations.

Our study is focused on the latter, which has received very little attention in past and recent years. We present results of multi-scale thermal imaging of the volcanic lake and its surroundings (100's of meters to millimeters) and direct subsurface measurements of groundwater temperature, hydraulic head, and electrical conductivity (EC) along a vertical 2D transect ( nearly equal 8 sq.m) at the bank. Thermal imaging of the entire caldera identified and reaffirmed warm sections where soil temperatures reach >70 C. Closer inspection and imaging at the meter scale revealed an abundance of seeps along the banks in the warm section of the volcanic lake which otherwise have no visual manifestation (no discernible convection or pronounced springs). Optical velocimetry using high-frequency (sub-second) millimeter-scale thermal images of the seeps allows for quantification of seepage rates. Groundwater temperature, head, and EC were measured via piezometers instrumented with a multi-parameter probe. The water table (average depth nearly equal 43 cm) beside a seep had a gradient of 0.016 (m/m) towards the lake. Using a typical hydraulic conductivity for the bank sediment (coarse sand=10 m/d), groundwater flux is therefore 16 cm/d. However, head gradient along the entire 2D transect reaches as high as 7.15 (m/m) which suggests that groundwater flux towards the lake can be as much as 7.15 m/d. Temperature in the 2D transect varied from an average of 57 C near the water table to 72 C two meters below the water table. The thermal gradients for the transect range from 0.57 to 3.3 C /m. The EC of lake water is nearly equal 25,000 microS/cm, whereas the highest observed EC of groundwater is nearly equal 56,000 microS/cm; this occurs at the deepest measurement depth of two meters. However, a portion of the transect near the water table has an EC of nearly equal 8,500 microS/cm. This area of fresher water also has relatively cooler groundwater. This suggests recharge from recent rain events. Our results suggest a very active shallow hydrologic system which leads to large exchange fluxes of fluid and solute mass and energy between the lake and its adjacent aquifer. This aspect of volcanic lake and caldera energy-mass balance needs further attention in future studies since it may be important in large-scale dynamics.

Deposition of mineral dust has been shown to be an important process to mitigate such depletion in soils and ecosystems (e.g. Hawaii, Amazon Basin). However, the magnitude of its effect has hardly been quantified and little is known about the accession pathways. This study exploits a unique geomorphic setting of a Holocene sequence of sand dune ridges. This sequence combines an active dust flux gradient along the dunes downwind of a braided riverbed and, distal from the dust source, a chronosequence across the dunes (170-6500 y). Pedogenesis is very rapid with Spodosols developing after 1000 y under a thick organic root mat. Comparison of soil and ecosystem phosphorus (P) across the chronosequence and along the dust gradient on the 6500 y dune allows us to quantify the capacity of active dust deposition to alter the P pool and to determine the biogeochemical pathways by which P fluxes are assimilated under super-humid, high leaching conditions. Across both gradients, we quantified the P concentrations in tree foliage and the P fractions in the upper 50 cm of the soils (total P, organic P, apatite P, occluded P, non-occluded P), including solution 31P NMR spectroscopy of organic P in selected profiles. Soil P across the chronosequence follows the P evolution model of Walker and Syers (1976)--a 75% decline of total P within 6500 y due to strong leaching losses of apatite P (82% loss) coinciding with an increase in secondary P forms. Along the dust gradient, increasing eolian deposition towards the river from approximately 1000 m distance is associated with a decline of apatite P and an increase of organic P. Foliar P mirrors the total P and apatite P decline of the soils across the chronosequence with a steep decrease after 1000 y. Along the dust gradient, foliar P correlates with deposition rates and organic P. This positive correlation of dust deposition rates and organically bound P, and the concomitant negative correlation with apatite P, requires biological transformation of the mineral P in the dust prior to the dust being incorporated into the soil. We suggest a rapid assimilation of dust-derived mineral P by plants within the organic root mat and a conversion into organic P as part of the living biomass, finally returned to the soil with the dead biomass. We will also present results from 31P NMR spectroscopy to qualitatively discriminate between organic P in soils formed under high dust flux and organic P in soils derived only from in situ dune sand parent material.

The abruptness of the observed geochemical shifts and their coincidence with a sharp lithologic contact is explained as an artifact of a previously undetected hiatus of 0.8-1.4 million years at the boundary contact, but the values before and after the hiatus indicate that major oceanographic changes occurred at this time. super(87)Sr/ super(88)Sr increase by 0.000 200, [delta] super(13)C values decrease by 1.5ppt to 2.2ppt, and [delta] super(18)O values decrease by 1.0ppt (planktics) to 0.5ppt (benthics) across the hiatus. Further, both super(87)Sr/ super(88)Sr ratios and [delta] super(18)O values during the Albian are anomalously high. The super(87)Sr/ super(88)Sr values deviate from known patterns to such a degree that an explanation requires either the presence of inter-basin differences in seawater super(87)Sr/ super(88)Sr during the Albian or revision of the seawater curve. For [delta] super(18)O, planktic values in some Aptian samples likely reflect a diagenetic overprint, but preservation is excellent in the rest of the section. In well preserved material, benthic foraminiferal values are largely between 0.5 and 0.0ppt and planktic samples are largely between 0.0ppt to -1.0ppt, with a brief excursion to -2.0ppt during OAE 1b. Using standard assumptions for Cretaceous isotopic paleotemperature calculations, the [delta] super(18)O values suggest bottom water temperatures (at 1000 -1500 m) of 8-10 degree C and surface temperatures of 10-14 degree C, which are 4-6 degree C and 10-16 degree C cooler, respectively, than present-day conditions at the same latitude. The cool subtropical sea surface temperature estimates are especially problematic because other paleoclimate proxy data for the mid-Cretaceous and climate model predictions suggest that subtropical sea surface temperatures should have been the same as or warmer than at present. Because of their exquisite preservation, whole scale alteration of the analyzed foraminifera is an untenable explanation. Our proposed solution is a high evaporative fractionation factor in the early Albian North Atlantic that resulted in surface waters with higher [delta] super(18)O values at elevated salinities than commonly cited in Cretaceous studies. A high fractionation factor is consistent with high rates of vapor export and a vigorous hydrological cycle and, like the Sr isotopes, implies limited connectivity among the individual basins of the Early Cretaceous proto-Atlantic ocean. Key Points * Geochemical changes ~112 Ma linked to planktic foram extinctions * Excellent foraminifer preservation allows new insight to paleoceanography * Relatively positive d18O values indicate elevated salinity of N.

The Biodiversity Heritage Library has over 35 million pages and counting. It is now a collection of over 47,000 titles and 94,000 volumes, accessed by tens of thousands of users worldwide, but only a handful of library and technical staff manage the operations of the BHL. In order to juggle the tasks required to manage this digital library along with the assigned duties of their own home brick-and-mortar institutions, the Biodiversity Heritage Library has adopted a commercial, off-the-shelf issue tracking system to resolve problems and manage feedback from users. Using Countersoft's Gemini issue tracking software, BHL staff document and monitor user feedback to process scanning requests, correct metadata errors, replace missing or poorly scanned images, reconcile duplicate entries, address bugs associated with the BHL website, and answer reference inquiries.

This is an important issue because coral skeletons are routinely used for tropical paleoclimatic reconstructions. We analyzed coral skeletal samples collected simultaneously from neighboring colonies off Belize and found that those harboring different clades of Symbiodinium displayed significantly different skeletal oxygen isotopic compositions. We also found evidence for mean shifts in skeletal oxygen isotopic composition after coral bleaching (the loss and potential exchange of symbionts) in two of four longer coral cores from the Mesoamerican Reef, though all experienced similar climatic conditions. Thus, we suggest that symbiont clade identity leaves a signature in the coral skeletal archive and that this influence must be considered for quantitative environmental reconstruction. In addition, we suggest that the skeletal isotopic signature may be used to identify changes in the dominant symbiont clade that have occurred in the past, to identify how common and widespread this phenomenon is--a potential adaptation to climate change.

Several studies have discussed a potential linkage between North Pacific and Atlantic climate on various time scales. On decadal time scales no relationship could be confirmed, potentially due to sparse instrumental observations before 1950. Proxy data are limited and no multi-centennial high-resolution marine geochemical proxy records are available from the subarctic North Pacific. Here we present an annually-resolved record (1818-1967) of Mg/Ca variations from a North Pacific/ Bering Sea coralline alga that extends our knowledge in this region beyond available data. It shows for the first time a statistically significant link between decadal fluctuations in sea-level pressure (SLP) in the North Pacific and North Atlantic. The record is a lagged proxy for decadal-scale variations of the Aleutian Low. It is significantly related to regional sea surface temperature (SST) and the North Atlantic Oscillation (NAO) index in late boreal winter on these time scales. Our data show that on decadal time scales a weaker Aleutian Low precedes a negative NAO by several years. This atmospheric link can explain the coherence of decadal North Pacific and Atlantic Multidecadal Variability (AMV), as suggested by earlier studies using climate models and limited instrumental data.

In this study, high-resolution stable isotopes have been performed on 13 serially-sampled Conus shells collected from both Caribbean and East Pacific coastal waters across the Panama Isthmus to examine their fidelity as proxies for upwelling and freshwater influx signals. The delta 13C profiles show three patterns: short-term invariant while long-term decreasing; short-term invariant while long-term increasing; co-variant with delta 18O values. Most of the delta 18O- delta 13C correlations, when occurring, are positive, indicating overwhelming influence of freshwater influx rather than upwelling. Using modern temperature and salinity (converted to seawater delta 18O) records from ocean data loggers and Ocean Data View (ODV) database, expected delta 18O profiles have been determined to: 1) establish a chronology for each specimen; 2) compare with measured delta 18O and 3) provide baseline values for shell delta 18O variations. Growth curves based on the shell chronology show: 1) fast growth during spring-summer within each year, suggesting the influence of seasonal upwelling; 2) faster growth in the first one or two years, the turning point of which are generally coincident with their spawning season. Most measured shell delta 18O values are 0.6 nearly equal 2.4ppm lighter than expected ones, especially those from the East Pacific upwelling area (1.4 nearly equal 2.4ppm lighter), suggesting greater overall influence of freshwater influx than upwelling. The ranges of measured shell delta 18O values from Caribbean and East Pacific are 0.2 nearly equal 1.7ppm lower and 0.1 nearly equal 1.0ppm higher than the expected delta 18O values, respectively. This is related to the different sampling localities (nearshore for the shell specimens and open sea for the loggers and ODV data) and perhaps sampling resolution (weekly to fortnightly for the stable analyses and monthly for the ODV data). Baseline delta 18O values have been estimated from the ODV data assuming average temperature during non-upwelling periods and normal salinity, and thus free of upwelling or freshening influence. The shell delta 18O values higher than the baselines are used to quantify the temperature of upwelled water and those lower than the baselines are used to quantify the salinity variations caused by the freshening. Results show that the Caribbean shell delta 18O values are generally lower than or very close to the baseline values, suggesting little upwelling signal while the East Pacific upwelling area shell delta 18O values periodically fluctuate across the baselines, reflecting influence of both upwelling and freshwater influx.

The associated extinction event began ca. 3-2 Ma, peaking between 2-1 Ma. More than two dozen "faunules", discreet packages of fauna which lived under similar environmental conditions, represent time just prior to, during, and after the uplift of the CAI. Multiple parameters including the amount and types of fauna present in each faunule have been used to estimate factors such as paleodepth, MART, extinction rates, and changes in ecological structure over time. Oxygen and carbon isotope analyses (delta 18O and delta 13C) of gastropod shells serially-sampled about the spire provide records of seasonal environmental conditions. In the tropics, gastropods that live under conditions of strong seasonal upwelling and freshwater input have a greater range of delta 18O values in their profiles compared to those animals that live in non-upwelling waters with little freshwater input. Low delta 13C values often represent the isotopically low terrestrial carbon found in river runoff, and may be coupled with low delta 18O values during seasonal freshening of marine waters. Preliminary data from Strombus shells representing four faunules ranging in age from before the rise of the isthmus through its completion demonstrate the effectiveness of using these mollusks to study ancient tropical environments. Rio Limoncito ( nearly equal 3 Ma), which is believed to represent water depths of 20-40m based on foraminiferal assemblage, yielded the lowest delta 18O values (-0.6+ or -0.4ppm, representing the warmest temperatures/lowest salinities). The samples from Pueblo Nuevo ( nearly equal 1.6 Ma), with an estimated paleodepth between 50 and 100m, had an average value of 0.4+ or -0.3ppm and therefore represent cooler waters/higher salinity. A shell from NE Escudo de Veraguas ( nearly equal 3.55 Ma) shows a shift from essentially constant values of 0.3+ or -0.2ppm to 1.8+ or -0.1ppm over nearly equal 4 mm of shell growth. The high and invariant values are consistent with the 100-150m paleodepth determination, with the delta 18O shift suggesting downslope transport of the specimen from shallower (50-100 m) depths. Overall, these shell averages are similar to estimated delta 18O values for aragonite precipitated under modern temperature and salinity conditions in the region at the depths they are believed to inhabit. A shell from Punta Tiburon to Punta Piedra (4.25 Ma; unknown paleodepth) falls within the range of the shell from NE Escudo de Veraguas, and therefore likely lived between 50 and 150m deep. The Pueblo Nuevo shell shows a strong positive correlation between delta 13C and delta 18O (R2=0.76). This may represent freshening of local waters, where lower delta 18O values caused by freshwater input are associated with lower delta 13C values associated with the influx of isotopically low terrestrial carbon. The shell representing shallowest waters (Rio Limoncito) shows a freshening signal in delta 18O values, but not in delta 13C values, which are fairly static with a slight increase during later life.

The most recent full transition from a cool earth to a warm world took place in the Early to Middle Permian. Against a background of global warming, plant communities were affected globally resulting in migrations, extinctions and changed evolutionary patterns as a response to the environmental changes. The collapse of the southern hemisphere ice-sheets resulted in significant changes, not just at higher latitudes, but also in the tropics where the rainfall regime changed from seasonally dry to seasonally wet. In the Early Permian tropics - in areas where net sedimentation facilitates fossilization, to be more specific - vegetation rich in walchian conifers began to replace the spore plants and seed ferns that previously dominated the Late Pennsylvanian wetlands. The replacing drier floras probably lived in the basinal lowlands as well, but episodically at the drier times of climate cycles. New finds within the tropics of latest Early to Middle Permian-age, in particular from north-central Texas, indicate the existence of floras which were adapted to even more extended periods of drought. These were populated by the more derived voltzian conifers and other seed plants, such as cycads. Surprisingly, the clades in these floras were until recently only known from the tens-of-millions-of-years younger Late Permian and Early Mesozoic, where they were the dominant forms. These occurrences demonstrate that even more derived groups were already in existence and well differentiated by the Early Permian, outside the window of preservation. This pattern of change in conifers and their communities from north-central Texas is unique in that it represents the best documented record in the Phanerozoic of terrestrial ecosystem response to a change from a global cool-mode to warm-mode Earth. Conifers serve as "marker plants" for the progressively more derived and more xeric floras that appear during the advancing deglaciation. This record has the potential to serve as a model for the early evolution of conifers and their communities; and the impact of prolonged climate change on the evolution of such land plants.

Seawater moving through these passes is the dominant source of water along the eastern slope of the Bering Sea, an oceanographically and ecologically significant region that is already changing in response to increasing global temperatures. However, the paucity of high-quality, high-resolution instrumental seawater temperature data extending prior to the mid-20th century prevents an understanding of how these recent changes relate to longer-term climate patterns. The long-lived crustose coralline alga Clathromorphum nereostratum is proving to be a climate archive that yields proxy records able to fill this data gap. This alga is endemic to the North Pacific/Bering Sea region and forms a dominant component of the shallow seafloor along the Aleutian Island arc. Sclerochronological and geochemical measurements of the high-Mg calcite skeleton of C. nereostratum can yield sub-annually resolved, multi-centennial reconstructions of past climatic variability. Here, we measured Mg/Ca ratios across the growth axis in multiple live-collected and subfossil specimens from two Aleutian Islands as a proxy for past surface seawater temperatures. By applying chronologies developed from U/Th dates combined with counts of annual growth rings to the Mg/Ca records, we reconstructed past seawater temperature variability extending from 1658 to 2006. In the record, the significant mode of variability shifted from interdecadal to lower frequency (>50 year) oscillations around the 1850s. In addition, the record significantly correlated with climate patterns spanning from the tropical Pacific to the Arctic Ocean, highlighting the complexity of factors driving the oceanography and climate along the Aleutian archipelago.

The Everglades receives some of the highest levels of atmospheric mercury deposition and has some of the highest levels of MeHg in fish in the USA, posing a threat to pisciverous wildlife and people through fish consumption. USGS studies show that a combination of biogeochemical factors make the Everglades especially susceptible to MeHg production and bioaccumulation: (1) vast wetland area with anoxic soils supporting anaerobic microbial activity, (2) high rates of atmospheric mercury deposition, (3) high levels of dissolved organic carbon (DOC) that complexes and stabilizes mercury in solution for transport to sites of methylation, and (4) high sulfate loading in surface water that drives microbial sulfate reduction and mercury methylation. The high levels of sulfate in the Everglades represent an unnatural condition. Background sulfate levels are estimated to be <1 mg/L, but about 60% of the Everglades has surface water sulfate concentrations exceeding background. Highly sulfate-enriched marshes in the northern Everglades have average sulfate levels of 60 mg/L. Sulfate loading to the Everglades is principally a result of land and water management in south Florida. The highest concentrations of sulfate, averaging 60-70 mg/L, are in canal water in the Everglades Agricultural Area (EAA). Geochemical data and a preliminary sulfur mass balance for the EAA are consistent with sulfur currently used in agriculture, and sulfur released by oxidation of organic EAA soils (including legacy agricultural applications and natural sulfur) as the primary sources of sulfate enrichment to the canals and ecosystem. Sulfate loading increases microbial sulfate reduction and MeHg production in soils. The relationship between sulfate loading and MeHg production, however, is complex. Sulfate levels up to about 20-30 mg/L increase mercury methylation, but buildup of sulfide from microbial sulfate reduction begins to inhibit mercury methylation above this range. Sulfate from the EAA canals has primarily impacted the northern Everglades nearest the EAA, but recent evidence shows sulfate loading extending about 80 km further south into Everglades National Park. Current restoration plans to restore to deliver more water south to Everglades National Park may increase overall sulfur loads to the southern part of the ecosystem. A comprehensive Everglades restoration strategy should include reduction of sulfur loads as a goal because of the many detrimental impacts of sulfate on the ecosystem. Monitoring data show that the ecosystem response to changes in sulfate levels is rapid, and strategies for reducing sulfate loading may be effective in the near-term. A multifaceted approach employing best management practices for sulfur in agriculture, agricultural practices that minimize soil oxidation, and changes to stormwater treatment areas that increase sulfate retention, could help reduce sulfate loads to the Everglades, with resulting benefits.

The biogeochemical basis for these field observations is unknown however. Here, we investigate the roles of DOM and sulfide in controlling Hg bioavailability to the Hg-methylating bacterium Desulfovibrio desulfuricans ND132 in short-term washed cell assays. At environmentally relevant Hg/DOM ratios (2-4300 ng Hg/mg DOM), MeHg production increased linearly with increasing Suwannee River humic acid (SRHA) concentration, even in the presence of sulfide concentrations (5-10 mu M) sufficient to outcompete SRHA for inorganic Hg. The DOM-dependent enhancement in Hg-methylation cannot be attributed to an enhancement of ND132 metabolic activity or alteration of Hg sorption to cells or bottle walls. Equilibrium speciation calculations indicated that cell suspensions were supersaturated with respect to metacinnabar (beta -HgS(s)) and that Hg-DOM thiol complexes were relatively minor species. Notably, SRHA addition had no effect on Hg methylation in solutions where Hg-cysteine species predominated and beta -HgS(s) precipitation was not predicted. We hypothesize that DOM enhances Hg-methylation by stabilizing HgS(s) colloids or nanoparticles against aggregation and/or by reducing the crystallinty of HgS(s) particles, and that such HgS(s) colloids are bioavailable to Hg-methylating bacteria. Ongoing work in the laboratory is evaluating the role of DOM character (size, aromaticity, reduced S content, etc.) in controlling the extent of the enhancement in MeHg production. These findings highlight the limits of equilibrium speciation approaches to predicting Hg bioavailability to methylating bacteria given the demonstrated significance of Hg-DOM-sulfide interactions in the anoxic environments where methylation occurs. Our laboratory experiments provide additional insight into the role that DOM plays in determining spatial and temporal patterns of MeHg production.

The PETM is recorded in pedogenic carbonate, bulk organic matter, and n-alkanes as a prominent negative carbon isotope excursion (CIE) in paleosols exposed in the Bighorn Basin, WY. Here we present a composite stable carbon isotope record from n-alkanes and dispersed soil organic delta (super 13) C records from five individual sections that span the PETM in the southeastern Bighorn Basin. Four sections are from a 10 km transect in the Cabin Fork area and one section was collected at Sand Creek Divide. These five new dispersed organic carbon (DOC) isotope records are compared to the previously published Polecat Bench (Magioncalda et al. 2004) and Honeycombs (Yans et al. 2006) isotope records. The high-resolution n-alkane curve shows an abrupt, negative shift in delta (super 13) C values, an extended CIE body, and a rapid recovery to more positive delta (super 13) C values. Although the five DOC records show similarly abrupt negative shifts in delta (super 13) C values, the DOC CIEs are compressed, smaller in magnitude, and return to more positive delta (super 13) C values more gradually relative to the n-alkane record. Moreover, the stratigraphic thickness of the body of the excursion and the pattern of the recovery phase are not consistent among the five DOC records. We modeled predicted DOC delta (super 13) C values from the n-alkane record by applying enrichment factors based on modern plants to the n-alkane delta (super 13) C values. The anomaly, difference between the expected and observed DOC delta (super 13) C values, was calculated for the PETM records and compared to weight percent carbon and grain size. There is no correlation between pre- and post-PETM anomaly values and grain size or weight percent carbon. PETM anomaly values, however, do trend with both grain size and weight percent carbon. The largest PETM anomaly values correspond to the highest grain sizes and lowest weight percent carbon. We hypothesize that the difference between the n-alkane and DOC delta (super 13) C records is due to contamination of the DOC delta (super 13) C signal by weathering of older, refractory Jurassic-Cretaceous carbon. According to this hypothesis, before and after the CIE the difference in the isotopic composition of autochthonous (Cenozoic) and allochthonous (Jurassic-Cretaceous) organic matter would have been small because C3 plants in the Jurassic-Cretaceous and pre- and post-PETM had relatively similar values. Thus, the ratio of autochthonous: allochthonous organic matter would be uncorrelated with isotopic composition. During the CIE, the isotopic composition of autochthonous organic carbon decreased dramatically. Therefore, autochthonous and allochthonous carbon pools were isotopically distinct and a correlation between weight percent carbon and isotopic composition is expected: the lower the weight percent carbon, the higher the proportion of allochthonous carbon, the larger the anomaly.

They can be preserved across a wide range of terrestrial and marine environments, survive in the sedimentary record for millions of years, and can serve as proxies for ancient environments. Most n-alkane records are derived from sediments rather than directly from fossil leaves. However, little is known about the fidelity of the n-alkane record: how and where leaf preservation relates to n-alkane preservation and how patterns of n-alkane carbon isotope ratios (delta 13C) compare to living relatives. To examine these questions, we analyzed n-alkanes from fluvial sediments and individual leaf fossils collected in the Bighorn Basin, Wyoming, across the Paleocene-Eocene Thermal Maximum (PETM) carbon isotope excursion. We assessed the fidelity of the n-alkane signature from individual fossil leaves via three separate means. 1) Spatial variations were assessed by comparing n-alkane concentrations on a fossil leaf and in sediments both directly adjacent to the leaf and farther away. Absolute concentrations were greater within the compression fossil than in the directly adjacent sediment, which were in turn greater than in more distant sediment. 2) n-Alkane abundances and distributions were examined in fossil leaves having a range of preservational quality, from fossils with intact cuticle to carbonized fossils lacking cuticle and higher-order venation. The best preserved fossils preserved a higher concentration of n-alkanes and showed the most similar n-alkane distribution to living relatives. However, a strong odd over even predominance suggests a relatively unmodified plant source occurred in all samples regardless of preservation state. 3) n-Alkane delta 13C values were measured for both fossil leaves and their living relatives. Both the saw-tooth pattern of delta 13C values between odd and even chain lengths and the general decrease in delta 13C values with increasing chain length are consistent with modern plant data. These results suggest that n-alkanes extracted directly from a fossil leaf provide a true signature of an individual leaf fossil rather than a mixture from the entire plant community. Therefore, comparisons between fossil morphotypes and between fossil and related modern taxa should be robust. Furthermore, by placing fossil leaf data within the context of the chemostratigraphy of Bighorn Basin sediments across the P-E boundary, fossil leaf n-alkanes can be used to bridge the gap between our understanding of modern plant lipids and bulk lipid data from sediments across the PETM. It has been hypothesized that changes in the both the molecular distribution and carbon isotope composition of n-alkanes across the PETM were due to changes in the local plant community, which included a large proportion of deciduous gymnosperms before and after--but not during--the PETM. Analysis of fossils such as Ginkgo and angiosperms provides the opportunity to compare and distinguish the molecular and isotopic signatures of gymnosperms and angiosperms. These comparisons shed light on the dynamics of climate and ecosystem changes as they are recorded in the signatures of lipid biomarkers.

Major efforts include the development of formal data- assimilation tools and the datasets for them. A key initial effort is to compile high quality data on the composition of North American forests at the time of Euro-American settlement, as a check point for the vegetation simulations, and to calibrate statistical models for inferring vegetation composition from fossil data. The primary data sources are witness tree datasets combined from the Public Lands Survey and lotting surveys from the northeastern states. PalEON is producing a 5-minute gridded dataset that stores information on the relative abundance of tree species at each grid cell for the entire PalEON domain (Great Lakes to New England) with additional information such as estimates of tree density or basal area stored where available. Compiling a settlement-era vegetation map from heterogeneous and time-transgressive data sources raises challenges of data quality and standardization, particularly with respect to sampling method and species identification by the original surveyors. We discuss these challenges, the error-mitigation efforts, products arising from the analysis, and planned applications.

In this paper we evaluate the complex linkages existing among the social-ecological history, provision of ecosystem services and human well-being as perceived by local stakeholders. The most critical anthropogenic impacts occurred during the last 50 years in the period following the construction of the Cienaga-Barranquilla highway. The changes to the social-ecological system have severely altered hydrological dynamics, reduced mangrove forest coverage and affected the composition of fisheries, with direct and indirect effects on the ecosystem services provision and on the well-being of the local people. Despite the ambitious restoration programmes put in practice during the last two decades, the social-ecological impacts of large infrastructure developments are visible today. The paper offers insights that can improve environmental decision making and promote adaptive governance in coastal wetlands. Editor Z.W. Kundzewicz; Guest editor M.C.

Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets. This information helps to guide numerical models for the three stages of planet formation from dust to planetesimals ( approximately 10 (super 6) y), followed by planetesimals to embryos (lunar to Mars-sized objects; few X 10 (super 6) y), and finally embryos to planets (10 (super 7) -10 (super 8) y). Defining the role of turbulence in the early nebula is a key to understanding the growth of solids larger than meter size. The initiation of runaway growth of embryos from planetesimals ultimately leads to the growth of large terrestrial planets via large impacts. Dynamical models can produce inner Solar System configurations that closely resemble our Solar System, especially when the orbital effects of large planets (Jupiter and Saturn) and damping mechanisms, such as gas drag, are included. Experimental studies of terrestrial planet interiors provide additional constraints on the conditions of differentiation and, therefore, origin. A more complete understanding of terrestrial planet formation might be possible via a combination of chemical and physical modeling, as well as obtaining samples and new geophysical data from other planets (Venus, Mars, or Mercury) and asteroids.

High temperature grains formed in the innermost region of the solar system ended up much farther out in the solar system, not only the asteroid belt but even in the comet accretion region, suggesting a huge and efficient process of mass transport. Bi-polar outflows, turbulent diffusion, and marginal gravitational instability are the likely mechanisms for this transport. The presence of short-lived radionuclides in the early solar system, especially (super 60) Fe, (super 26) Al, and (super 41) Ca, requires a nearby supernova shortly before our solar system was formed, suggesting that the Sun was formed in a massive star-forming region similar to Orion or Carina. Solar system formation may have been "triggered" by ionizing radiation originating from massive O and B stars at the center of an expanding HII bubble, one of which may have later provided the supernova source for the short-lived radionuclides. Alternatively, a supernova shock wave may have simultaneously triggered the collapse and injected the short-lived radionuclides. Because the Sun formed in a region where many other stars were forming more or less contemporaneously, the bi-polar outflows from all such stars enriched the local region in interstellar silicate and oxide dust. This may explain several observed anomalies in the meteorite record: a near absence of detectable (no extreme isotopic properties) presolar silicate grains and a dichotomy in the isotope record between (super 26) Al and nucleosynthetic (nonradiogenic) anomalies.

It is shown that IOM is composed primarily of highly substituted single ring aromatics, substituted furan/pyran moieties, highly branched oxygenated aliphatics, and carbonyl groups. A pathway for producing an IOM-like molecular structure through formaldehyde polymerization is proposed and tested experimentally. Solid-state (super 13) C NMR analysis of aqueously altered formaldehyde polymer reveals considerable similarity with chondritic IOM. Carbon X-ray absorption near edge structure spectroscopy of formaldehyde polymer reveals the presence of similar functional groups across certain Comet 81P/Wild 2 organic solids, interplanetary dust particles, and primitive IOM. Variation in functional group concentration amongst these extraterrestrial materials is understood to be a result of various degrees of processing in the parent bodies, in space, during atmospheric entry, etc. These results support the hypothesis that chondritic IOM and cometary refractory organic solids are related chemically and likely were derived from formaldehyde polymer. The fine-scale morphology of formaldehyde polymer produced in the experiment reveals abundant nanospherules that are similar in size and shape to organic nanoglobules that are ubiquitous in primitive chondrites.

Instrumental advances have been made along two lines: (i) increase in spatial resolution and sensitivity of detection, allowing for the study of increasingly smaller samples, and (ii) increase in the precision of isotopic analysis that allows more precise dating, the study of isotopic heterogeneity in the Solar System, and other studies. A variety of instrumental techniques are discussed, and important examples of discoveries are listed. Instrumental techniques and instruments include the ion microprobe, laser ablation gas MS, Auger EM, resonance ionization MS, accelerator MS, transmission EM, focused ion-beam microscopy, atom probe tomography, X-ray absorption near-edge structure/electron loss near-edge spectroscopy, Raman microprobe, NMR spectroscopy, and inductively coupled plasma MS.

Despite indirect hints, direct evidence of a martian origin came with the discovery of trapped atmospheric gases in one meteorite. Since then, the study of martian meteorites and findings from missions have been linked. Although the meteorite source locations are unknown, impact ejection modeling and spectral mapping of Mars suggest derivation from small craters in terrains of Amazonian to Hesperian age. Whereas most martian meteorites are young ( 4.5 Ga and formation of enriched and depleted reservoirs. However, the history inferred from martian meteorites conflicts with results from recent Mars missions, calling into doubt whether the igneous history inferred from the meteorites is applicable to Mars as a whole. Allan Hills 84001 dates to 4.09 Ga and contains fluid-deposited carbonates. Accompanying debate about the mechanism and temperature of origin of the carbonates came several features suggestive of past microbial life in the carbonates. Although highly disputed, the suggestion spurred interest in habitable extreme environments on Earth and throughout the Solar System. A flotilla of subsequent spacecraft has redefined Mars from a volcanic planet to a hydrologically active planet that may have harbored life. Understanding the history and habitability of Mars depends on understanding the coupling of the atmosphere, surface, and subsurface. Sample return that brings back direct evidence from these diverse reservoirs is essential.

However, the evolutionary diversification of this group after its initial radiation but prior to the Triassic-Jurassic boundary is still poorly understood because of a sparse fossil record near that boundary. Here, we report on a new basal theropod, Daemonosaurus chauliodus gen. et sp. nov., from the latest Triassic "siltstone member" of the Chinle Formation of the Coelophysis Quarry at Ghost Ranch, New Mexico. Based on a comprehensive phylogenetic analysis, Daemonosaurus is more closely related to coeval neotheropods (e.g. Coelophysis bauri) than to Herrerasauridae and EORAPTOR: The skeletal structure of Daemonosaurus and the recently discovered Tawa bridge a morphological gap between Eoraptor and Herrerasauridae on one hand and neotheropods on the other, providing additional support for the theropod affinities of both Eoraptor and Herrerasauridae and demonstrating that lineages from the initial radiation of Dinosauria persisted until the end of the Triassic. Various features of the skull of Daemonosaurus, including the procumbent dentary and premaxillary teeth and greatly enlarged premaxillary and anterior maxillary teeth, clearly set this taxon apart from coeval neotheropods and demonstrate unexpected disparity in cranial shape among theropod dinosaurs just prior to the end of the Triassic.

Its highly bipolar geometry and dense massive disc, coupled with the very wide range of ions present, from neutral species up to Si8 +, make it one of the ultimate challenges to nebular photoionization modelling. Our mocassin model is composed of an extremely dense geometrically thin circumstellar disc and a large pair of diffuse bipolar lobes, a combination which was necessary to reproduce the observed emission-line spectrum. The masses of these components, 2.2 M[odot] and 2.5 M[odot], respectively, give a total nebular mass of 4.7 M[odot], of which 1.8 M[odot] (39 per cent) is ionized. Discrepancies between our model fit and the observations are attributed to complex density inhomogeneities in the nebula. The potential to resolve such discrepancies with more complex models is confirmed by exploring a range of models introducing small-scale structures. Compared to solar abundances helium is enhanced by 50 per cent, carbon is slightly subsolar, oxygen is solar, and nitrogen is enhanced by a factor of 6. These all imply a significant third dredge-up coupled with hot-bottom burning CN-cycle conversion of dredged-up carbon to nitrogen. Aluminium is also depleted by a factor of 100, consistent with depletion by dust grains. The central star of NGC 6302 is partly obscured by the opaque circumstellar disc, which is seen almost edge-on, and as such its properties are not well constrained. However, emission from a number of high-ionization 'coronal' lines provides a strong constraint on the form of the high-energy ionizing flux. We model emission from the central star using a series of stellar model atmospheres, the properties of which are constrained from fits to the high-ionization nebular emission lines. Using a solar abundance stellar atmosphere we are unable to fit all of the observed line fluxes, but a substantially better fit was obtained using a 220000K hydrogen-deficient stellar atmosphere with logg= 7.0 and L[starf= 14300L[odot]. The H-deficient nature of the central star atmosphere suggests that it has undergone some sort of late thermal pulse, and fits to evolutionary tracks imply a central star mass of 0.73-0.82 M[odot]. Time-scales for these evolutionary tracks suggest the object left the top of the asymptotic giant branch similar to 2100 years ago, in good agreement with studies of the recent mass-loss event that formed one pair of the bipolar lobes. Based on the modelled nebular mass and central star mass we estimate the initial mass of the central star to be 5.5 M[odot], in approximate agreement with that derived from evolutionary tracks.

Including our previously published data, we analyze 56 TTS and 3 intermediate-mass stars with silicate features in Tr 37 ( approximately 4 Myr) and NGC 7160 ( approximately 12 Myr). The silicate emission features are well reproduced with a mixture of amorphous (with olivine, forsterite, and silica stoichiometry) and crystalline grains (forsterite, enstatite). We explore grain size and disk structure using radiative transfer disk models, finding that most objects have suffered substantial evolution (grain growth, settling). About half of the disks show inside-out evolution, with either dust-cleared inner holes or a radially dependent dust distribution, typically with larger grains and more settling in the innermost disk. The typical strong silicate features nevertheless require the presence of small dust grains, and could be explained by differential settling according to grain size, anomalous dust distributions, and/or optically thin dust populations within disk gaps. M-type stars tend to have weaker silicate emission and steeper spectral energy distributions than K-type objects. The inferred low dust masses are in a strong contrast with the relatively high gas accretion rates, suggesting global grain growth and/or an anomalous gas-to-dust ratio. Transition disks in the Cep OB2 region display strongly processed grains, suggesting that they are dominated by dust evolution and settling. Finally, the presence of rare but remarkable disks with strong accretion at old ages reveals that some very massive disks may still survive to grain growth, gravitational instabilities, and planet formation.

AN - 904495252; 15950874 AB - NMR-guided fractionation of a non-polar extract of a Florida Keys collection of Lyngbya sp. resulted in the isolation of two novel epimeric cyclic depsipeptides, porpoisamides A (1) and B (2). The planar structures of these compounds were determined using NMR spectroscopic techniques. The absolute configurations of amino and hydroxy acid subunits were assigned by enantioselective HPLC analysis. These compounds showed weak cytotoxicity towards HCT-116 colorectal carcinoma and U2OS osteosarcoma cells. The porpoisamides are a unique pair of cyclic depsipeptides that are epimeric at C-2 of the I super(2)-amino acid, 3-amino-2-methyloctanoic acid.

preliminary results AN - 1464886383; 2013-094683 AB - The NEOWISE data set offers the opportunity to study the variations in albedo for asteroid classification schemes based on visible and near-infrared observations for a large sample of minor planets. We have determined the albedos for nearly 1900 asteroids classified by the Tholen, Bus, and Bus-DeMeo taxonomic classification schemes. We find that the S-complex spans a broad range of bright albedos, partially overlapping the low albedo C-complex at small sizes. As expected, the X-complex covers a wide range of albedos. The multiwavelength infrared coverage provided by NEOWISE allows determination of the reflectivity at 3.4 and 4.6 mu m relative to the visible albedo. The direct computation of the reflectivity at 3.4 and 4.6 mu m enables a new means of comparing the various taxonomic classes. Although C, B, D, and T asteroids all have similarly low visible albedos, the D and T types can be distinguished from the C and B types by examining their relative reflectance at 3.4 and 4.6 mu m. All of the albedo distributions are strongly affected by selection biases against small, low albedo objects, as all objects selected for taxonomic classification were chosen according to their visible light brightness. Due to these strong selection biases, we are unable to determine whether or not there are correlations between size, albedo, and space weathering. We argue that the current set of classified asteroids makes any such correlations difficult to verify. A sample of taxonomically classified asteroids drawn without significant albedo bias is needed in order to perform such an analysis. Copyright (Copyright) 2011. The American Astronomical Society.

Using a NEATM thermal model fitting routine, we compute diameters for over 100,000 Main Belt asteroids from their IR thermal flux, with errors better than 10%. We then incorporate literature values of visible measurements (in the form of the H absolute magnitude) to determine albedos. Using these data we investigate the albedo and diameter distributions of the Main Belt. As observed previously, we find a change in the average albedo when comparing the inner, middle, and outer portions of the Main Belt. We also confirm that the albedo distribution of each region is strongly bimodal. We observe groupings of objects with similar albedos in regions of the Main Belt associated with dynamical breakup families. Asteroid families typically show a characteristic albedo for all members, but there are notable exceptions to this. This paper is the first look at the Main Belt asteroids in the WISE data, and only represents the preliminary, observed raw size, and albedo distributions for the populations considered. These distributions are subject to survey biases inherent to the NEOWISE data set and cannot yet be interpreted as describing the true populations; the debiased size and albedo distributions will be the subject of the next paper in this series.

Despite federal and state regulations that require ballast water exchange (BWE), particular trade routes impose geographic and temporal constraints on compliance, limiting whether a ship can conduct BWE at the required distance ( greater than or equal to 200 nautical miles) from shore to minimize transfers of coastal organisms. Ships moving across the Americas are largely unable to conduct open-ocean BWE, but instead often conduct exchanges inside coastal waters. Overall, strong differences exist in volumes, geographic sources, and the use of BWE for ballast water discharge among the three major coasts of the contiguous United States. Such patterns suggest important geographic differences in invasion opportunities and also argue for more effective alternative ballast water treatments that can be applied more evenly.

The Escudo Hummingbird (A. t. handleyi), the most distinctive of the five subspecies of A. tzacatl, is endemic to Isla Escudo in Caribbean western Panama. Mitochondrial DNA (mtDNA) sequence variation from across most of the species' range showed five well-defined but shallow clades (maximum uncorrected distance 2.4%) that only partially agreed with subspecific taxonomy. A widespread Middle American clade ranges from southeastern Mexico to central Caribbean Panama and includes birds collected on the Bocas del Toro archipelago. The Escudo Hummingbird fell within this clade and was slightly differentiated (two unique substitutions; uncorrected distance similar to 0.2-0.5%). Two additional clades occur in the Pacific regions of southern Middle America. A fourth clade is endemic to eastern Panama (eastern Panama and Darien provinces); a fifth is found in northwestern South America and in Darien. Secondary contact between clades occurs at three sites: between clades I and III in northwestern Costa Rica, between clades I and II in western Panama, and between clades IV and V near the Panama-Colombia border. The last case is likely due to recent expansion into the region from two directions. Thus the history of Amazilia tzacatl demonstrates a tendency for the formation of monophyletic mtDNA clades, likely as the result of geographic isolation, but also a propensity for secondary contact of these clades, a phenomenon recovered in many other phylogeographic studies of neotropical birds.

Thus, just as an animal's view of its world, its Umwelt, determines how it interacts with its ecological niche, it can influence the evolution of its social niche. Thus, the brain is not only a landscape on which selection can act, but also it is a powerful source of selection on the animal's social niche.

This was consistent with climate models and lander measurements indicating that winds of sufficient intensity to mobilize sand were rare in the low-density atmosphere. We show that many sand ripples and dunes across Mars exhibit movement of as much as a few meters per year, demonstrating that Martian sand migrates under current conditions in diverse areas of the planet. Most motion is probably driven by wind gusts that are not resolved in global circulation models. A past climate with a thicker atmosphere is only required to move large ripples that contain coarse grains.

However, evidence for the existence of an autochthonous Stenian-Tonian belt in northern Amazonia that is undisturbed by Andean orogenesis has not been recognized so far. Here we report approximately 1200 new single-zircon U-Pb geochronological analyses from 19 Proterozoic rock samples of northwestern South America collected from the Garzon and Las Minas Andean cordilleran inliers, drill-core samples from the foreland basin basement, and outcrops of cratonic Amazonia in eastern Colombia (western Guyana shield). Our new geochronological results document the existence of a previously unrecognized Meso- to Neoproterozoic orogenic belt buried under the north Andean foreland basins, herein termed the Putumayo Orogen, which has implications for Proterozoic tectonic reconstructions of Amazonia during the assembly of the supercontinent Rodinia. Based on the interpretations of new and preexisting data, we propose a three-stage tectonometamorphic evolution for this orogenic segment characterized by: (1) development of a pericratonic fringing-arc system outboard of Amazonia's leading margin during Mesoproterozoic time from approximately 1.3 to 1.1 Ga, where the protoliths for metaigneous and metavolcanosedimentary units of the Colombian and Mexican inliers would have originated in a commonly evolving Colombian-Oaxaquian fringing-arc system; (2) amphibolite-grade metamorphism and migmatization between ca. 1.05 and 1.01 Ga by inferred amalgamation of these parautochtonous arc terranes onto the continental margin; and (3) granulite-grade metamorphism at approximately 0.99 Ga during continent-continent collision related to Rodinia final assembly. Along with additional paleogeographic constraints, this new geochronological framework suggests that the final metamorphic phase of the Putumayo Orogen was likely the result of collisional interactions with the Sveconorwegian province of Baltica, in contrast to previously proposed models that place this margin of Amazonia as the conjugate of the Grenville province of Laurentia.

The collision is significant because it ultimately led to development of the Panamanian Isthmus, which in turn had wide-ranging oceanic, climatic, biologic, and tectonic implications. Within the Panama Canal Zone, volcanic activity transitioned from hydrous mantle-wedge-derived arc magmatism to localized extensional arc magmatism at 24 Ma and overall marks a permanent change in arc evolution. We interpret the arc geochemical change to result from fracturing of the Panama block during initial collision with South America. Fracturing of the Panama block led to localized crustal extension, normal faulting, sedimentary basin formation, and extensional magmatism in the Canal Basin and Bocas del Toro. Synchronous with this change, both Panama and inboard South America experienced a broad episode of exhumation indicated by (U-Th)/He and fission-track thermochronology coupled with changing geographic patterns of sedimentary deposition in the Colombian Eastern Cordillera and Llanos Basin. Such observations allow for construction of a new tectonic model of the South America-Panama collision, northern Andes uplift and Panama orocline formation. Finally, synchroneity of Panama arc chemical changes and linked uplift indicates that onset of collision and Isthmus formation began earlier than commonly assumed.

However, few studies have assessed such Janzen-Connell mechanisms on a scale relevant for coexistence and no study has evaluated potential top-down influences on the specialized pests. We quantified seed predation by specialist invertebrates and generalist vertebrates, as well as larval predation on these invertebrates, for the Neotropical palm Attalea butyracea across ten 4-ha plots spanning 20-fold variation in palm density. As palm density increased, seed attack by bruchid beetles increased, whereas seed predation by rodents held constant. But because rodent predation on bruchid larvae increased disproportionately with increasing palm density, bruchid emergence rates and total seed predation by rodents and bruchids combined were both density-independent.

Because little is known about the biogeography and ecology of NES prior to the mid-nineteenth century, we synthesize and analyze the occurrence of NES remains in North American archaeological sites. Comparing these archaeological data with modern biogeographical, genetic, and behavioral data, we provide a trans-Holocene perspective on NES distribution and abundance. Compared with other pinnipeds, NES bones are relatively rare throughout The Holocene, even in California where they currently breed in large numbers. Low numbers of NES north of California match contemporary NES distribution, but extremely low occurrences in California suggest their abundance in this area was very different during The Holocene than today. We propose four hypotheses to explain this discrepancy, concluding that ancient human settlement and other activities may have displaced NES from many of their preferred modern habitats during much of The Holocene.

Here, we examine the fractionation of Cu isotopes during dissolution of another important Cu ore mineral, bornite, using a novel approach that combines time-resolved X-ray diffraction (XRD) and isotope analysis of reaction products. During the initial stages of bornite oxidative dissolution by ferric sulfate (20 mol% Cu was leached from the solid, the difference between the Cu isotope composition of the aqueous and mineral phases approached zero, with Delta (sub aq-min) (super 0) values ranging from -0.21+ or -0.61 ppm to 0.92+ or -0.25 ppm. XRD analysis allowed us to correlate changes in the atomic structure of bornite with the apparent isotope fractionation as the dissolution reaction progressed. These data revealed that the greatest degree of apparent fractionation is accompanied by a steep contraction in the unit-cell volume, which we identified as a transition from stoichiometric to non-stoichiometric bornite. We propose that the initially high Delta (sub aq-min) values result from isotopically heavy Cu ( (super 65) Cu) concentrating within Cu (super 2+) during dissolution. The decrease in the apparent isotope fractionation as the reaction progresses occurs from the distillation of isotopically heavy Cu ( (super 65) Cu) during dissolution or kinetic isotope effects associated with the depletion of Cu from the surfaces of bornite particles.

The transit signal with a period of 4.94 days was detected in the quarter 1 (Q1) Kepler photometry. For the first time, we have used the High Resolution Spectrograph (HRS) at the Hobby-Eberly Telescope (HET) to determine the mass of a Kepler planet via precise radial velocity (RV) measurements. The 24 HET/HRS RVs and 6 additional measurements from the Fibre-fed Echelle Spectrograph spectrograph at the Nordic Optical Telescope reveal a Doppler signal with the same period and phase as the transit ephemeris. We used one HET/HRS spectrum of Kepler-15 taken without the iodine cell to determine accurate stellar parameters. The host star is a metal-rich ([Fe/H]=0.36+ or -0.07) G-type main-sequence star with T (sub eff) =5515+ or -124 K. The semi-amplitude K of the RV orbit is 78.7 (super +8.5) (sub -9.5) m s (super -1) , which yields a planet mass of 0.66+ or -0.1 M (sub Jup) . The planet has a radius of 0.96+ or -0.06 R (sub Jup) and a mean bulk density of 0.9+ or -0.2 g cm (super -3) . The radius of Kepler-15b is smaller than the majority of transiting planets with similar mass and irradiation level. This suggests that the planet is more enriched in heavy elements than most other transiting giant planets. For Kepler-15b we estimate a heavy element mass of 30-40 M (sub Earth) .

Mid-IR observations, which span the peak of the thermal spectral energy distribution, provide useful constraints on the properties of the dust and, ultimately, the circumstellar environment, explosion mechanism, and progenitor system. Due to the low SN IIn rate (<10% of all core-collapse SNe), few IR observations exist for this subclass. The handful of isolated studies, however, show late-time IR emission from warm dust that, in some cases, extends for five or six years post-discovery. While previous Spitzer/IRAC surveys have searched for dust in SNe, none have targeted the Type IIn subclass. This paper presents results from a warm Spitzer/IRAC survey of the positions of all 68 known SNe IIn within a distance of 250 Mpc between 1999 and 2008 that have remained unobserved by Spitzer more than 100 days post-discovery. The detection of late-time emission from 10 targets ( approximately 15%) nearly doubles the database of existing mid-IR observations of SNe IIn. Although optical spectra show evidence for new dust formation in some cases, the data show that in most cases the likely origin of the mid-IR emission is pre-existing dust, which is continuously heated by optical emission generated by ongoing circumstellar interaction between the forward shock and circumstellar medium. Furthermore, an emerging trend suggests that these SNe decline at approximately 1000-2000 days post-discovery once the forward shock overruns the dust shell. The mass-loss rates associated with these dust shells are consistent with luminous blue variable progenitors. Copyright (Copyright) 2011. The American Astronomical Society. All rights reserved.

Data record initial flooding of a latest Pleistocene river drainage and the formation of an estuary 9000 yr ago. Estuarine conditions were punctuated by two intervals of marine influence from approximately 4100 to 3700 and 1150 to 500calyr BP. Foraminiferal assemblages in the muddy sand facies that accumulated during these intervals contain many well-preserved benthic foraminiferal species, which occur today in open marine settings as deep as the mid shelf, and significant numbers of well-preserved planktonic foraminifera, some typical of Gulf Stream waters. We postulate that these marine-influenced units resulted from temporary destruction of the southern Outer Banks barrier islands by hurricanes. The second increase in marine influence is coeval with increased rate of sea-level rise and a peak in Atlantic tropical cyclone activity during the Medieval Climate Anomaly. This high-resolution analysis demonstrates the range of environmental variability and the rapidity of coastal change that can result from the interplay of changing climate, sea level and geomorphology in an estuarine setting.

The data show that speakers exhibit a strong preference for the absolute and object-centered FoRs, both observer-independent, and overall disfavor most other FoR types. Of particular interest is the limited use of the relative (observer-dependent) FoR. This is relevant in a language such as Juchiteco, which has a productive meronymic (part-naming) system, as it supports the hypothesis put forth by the Spatial Language and Cognition in Mesoamerica project that productive meronymy correlates with a bias against the use of relative FoR.

This chemostratigraphic evolution reflects formation of what ultimately becomes forearc lithosphere as a result of mantle melting that is progressively influenced by subduction zone enrichment during SI. The magmatic chemostratigraphic progression for the Izu-Bonin-Mariana (IBM) forearc and most Tethyan ophiolites is specifically from MORB-like to arc-like (volcanic arc basalts or VAB + or - boninites or BON) because SI progressed until establishment of a mature subduction zone. MORB-like lavas result from decompression melting of upwelling asthenosphere and are the first magmatic expression of SI. The contribution of fluids from dehydrating oceanic crust and sediments on the sinking slab is negligible in early SI, but continued melting results in a depleted, harzburgitic residue that is progressively metasomatized by fluids from the sinking slab; subsequent partial melting of this residue yields 'typical' SSZ-like lavas in the latter stages of SI. If SI is arrested early, e.g., as a result of collision, 'MORB-only' ophiolites might be expected. Consequently, MORB- and SSZ-only ophiolites may represent end-members of the SI ophiolite spectrum. The chemostratigraphic similarity of the Mariana forearc with that of ophiolites that follow the SIR intimates that a model linking such ophiolites, oceanic forearcs, and SI is globally applicable.

Gravity models provide one of the most useful techniques available to model dispersal of nonindigenous invasive species (NIS) across heterogeneous landscapes, as these models are able to capture transport patterns of recreational boaters who are dominant vectors responsible for aquatic NIS dispersal. Despite the widespread use of gravity models in forecasting biological invasions, different classes of gravity models have not been evaluated regarding their comparative ability to capture recreational transport patterns and subsequent use in predicting NIS establishment. Here we evaluate model selection between unconstrained, total-flow-constrained, production-constrained and doubly-constrained stochastic gravity models to assess dispersal of the spiny waterflea Bythotrephes between Ontario lakes. Differences between the models relate to the amount of data required and constraints under which calculations of source/destination interactions are made. For each class of gravity model, we then estimated the probability of a lake having established Bythotrephes populations by modeling the relationship between empirical presence/absence data and inbound recreational traffic (i.e. propagule pressure) via boosted regression. The unconstrained gravity model provided the best fit to observed traffic patterns of recreational boaters. However, when output from the gravity models was used to predict Bythotrephes establishment, the doubly-constrained gravity model provided the strongest relationship between inbound recreational traffic and observed Bythotrephes presence/absence, followed by the production-constrained model. Our results indicate production-constrained gravity models offer an acceptable balance between modeling recreational boater traffic and their utility to estimate establishment probabilities.

[Part 13 of 13] T2 - ROSEMONT COPPER PROJECT, CORONADO NATIONAL FOREST, PIMA COUNTY, ARIZONA. AN - 912105302; 15107-0_0013 AB - PURPOSE: The development of an open-pit mine to extract locatable minerals such as copper, molybdenum, and silver on the Nogales Ranger District of the Coronado National Forest, Pima County, Arizona is proposed. The Rosemont Copper Project site is located on the east side of the Santa Rita Mountains, approximately 30 miles south of Tucson. Activity is proposed on approximately 995 acres of private land owned by Rosemont Copper, 3,670 acres of National Forest System (NFS) land, 15 acres of Bureau of Land Management (BLM) administered land, and 75 acres of State land. The mine life, including construction, operation, reclamation, and closure, would be approximately 25 years. Associated infrastructure would consist of haul and access roads, ore transportation systems, ore processing facilities, waste rock and tailings areas, leach facilities, electrical and water transmission lines, and ancillary facilities integral to the operations, such as the administration building, employee change house, warehouse, analytical laboratory, vehicle servicing facilities, storage facilities, guard house, and truck scale. The roughly circular open-pit mine would measure, at end of mine life, between 6,000 and 6,500 feet in diameter, with a final depth of 1,800 to 2,900 feet, depending on the elevation of the pit rim. The mine would produce a total of 550 million tons of ore and 1.3 billion tons of waste rock. Highway access would be from State Route 83, which connects to Interstate 10 approximately 12 miles north of the mine site. A new two-lane gravel road would be constructed to provide access between State Route 83 and the mine. The project would be located primarily within the Barrel Canyon drainage and its tributaries. Diversion channels would be constructed to intercept runoff from precipitation and route it around the mine facilities for discharge to lower Barrel Canyon, downstream of the project. The project would use 5,000 acre-feet per year of fresh water, for a total over the mine life of approximately 100,000 acre-feet. The water would be pumped from four to six wells located on land owned or leased by Rosemont Copper near the community of Sahuarita in the Santa Cruz Valley and would be piped to the mine. Six alternatives, including a No Action Alternative (Alternative 1) and the proposed action (Alternative 2), are considered in this draft EIS. Under the preferred Barrel Alternative (Alternative 4), all tailings and waste rock would be placed in Upper Barrel and Wasp Canyons. Two water line alignments and five alternative routes for an aboveground 138-kilovolt transmission line and an associated 14-foot-wide unpaved maintenance road are considered. POSITIVE IMPACTS: Implementation would allow development of the Rosemont ore deposit in a manner that complies with Federal, State, and local laws and regulations. Production estimates include 234 million pounds of copper, 4.5 million pounds of molybdenum, and 2.7 million ounces of silver annually over 20 years. The preferred alternative would avoid placement of mine waste in McCleary Canyon, thus preserving resource values, including recreation, riparian areas, and wildlife habitat. NEGATIVE IMPACTS: The preferred alternative would result in the loss of 39.9 acres of jurisdictional waters of the United States, the conversion of 7,014 to 7,095 acres of habitat, and potential impacts on up to 145,190 acres. Wildlife species impacted would include nine species federally listed as threatened or endangered. All of the action alternatives may result in a loss of population viability for two special status plant species. Numerous prehistoric and historic sites would be impacted. Modeling indicates that remnant heap leach seepage would exceed aquifer water quality standards for cadmium, nickel, and selenium. However, the heap leach facility would be located on top of a stable rock location and designed to collect all possible drainage and solution. Potential grazing activities would be reduced by 1,075 animal unit months. Blasting and equipment operational noise would result in a likely decrease in recreational value in the area. Long-term adverse impacts on astronomy would affect research at Whipple Observatory and Jarnac Observatory.

The roughly circular open-pit mine would measure, at end of mine life, between 6,000 and 6,500 feet in diameter, with a final depth of 1,800 to 2,900 feet, depending on the elevation of the pit rim. The mine would produce a total of 550 million tons of ore and 1.3 billion tons of waste rock. Highway access would be from State Route 83, which connects to Interstate 10 approximately 12 miles north of the mine site. A new two-lane gravel road would be constructed to provide access between State Route 83 and the mine. The project would be located primarily within the Barrel Canyon drainage and its tributaries. Diversion channels would be constructed to intercept runoff from precipitation and route it around the mine facilities for discharge to lower Barrel Canyon, downstream of the project. The project would use 5,000 acre-feet per year of fresh water, for a total over the mine life of approximately 100,000 acre-feet. The water would be pumped from four to six wells located on land owned or leased by Rosemont Copper near the community of Sahuarita in the Santa Cruz Valley and would be piped to the mine. Six alternatives, including a No Action Alternative (Alternative 1) and the proposed action (Alternative 2), are considered in this draft EIS. Under the preferred Barrel Alternative (Alternative 4), all tailings and waste rock would be placed in Upper Barrel and Wasp Canyons. Two water line alignments and five alternative routes for an aboveground 138-kilovolt transmission line and an associated 14-foot-wide unpaved maintenance road are considered. POSITIVE IMPACTS: Implementation would allow development of the Rosemont ore deposit in a manner that complies with Federal, State, and local laws and regulations. Production estimates include 234 million pounds of copper, 4.5 million pounds of molybdenum, and 2.7 million ounces of silver annually over 20 years. The preferred alternative would avoid placement of mine waste in McCleary Canyon, thus preserving resource values, including recreation, riparian areas, and wildlife habitat. NEGATIVE IMPACTS: The preferred alternative would result in the loss of 39.9 acres of jurisdictional waters of the United States, the conversion of 7,014 to 7,095 acres of habitat, and potential impacts on up to 145,190 acres. Wildlife species impacted would include nine species federally listed as threatened or endangered. All of the action alternatives may result in a loss of population viability for two special status plant species. Numerous prehistoric and historic sites would be impacted. Modeling indicates that remnant heap leach seepage would exceed aquifer water quality standards for cadmium, nickel, and selenium. However, the heap leach facility would be located on top of a stable rock location and designed to collect all possible drainage and solution. Potential grazing activities would be reduced by 1,075 animal unit months. Blasting and equipment operational noise would result in a likely decrease in recreational value in the area. Long-term adverse impacts on astronomy would affect research at Whipple Observatory and Jarnac Observatory.

[Part 9 of 13] T2 - ROSEMONT COPPER PROJECT, CORONADO NATIONAL FOREST, PIMA COUNTY, ARIZONA. AN - 912103694; 15107-0_0009 AB - PURPOSE: The development of an open-pit mine to extract locatable minerals such as copper, molybdenum, and silver on the Nogales Ranger District of the Coronado National Forest, Pima County, Arizona is proposed. The Rosemont Copper Project site is located on the east side of the Santa Rita Mountains, approximately 30 miles south of Tucson. Activity is proposed on approximately 995 acres of private land owned by Rosemont Copper, 3,670 acres of National Forest System (NFS) land, 15 acres of Bureau of Land Management (BLM) administered land, and 75 acres of State land. The mine life, including construction, operation, reclamation, and closure, would be approximately 25 years. Associated infrastructure would consist of haul and access roads, ore transportation systems, ore processing facilities, waste rock and tailings areas, leach facilities, electrical and water transmission lines, and ancillary facilities integral to the operations, such as the administration building, employee change house, warehouse, analytical laboratory, vehicle servicing facilities, storage facilities, guard house, and truck scale. The roughly circular open-pit mine would measure, at end of mine life, between 6,000 and 6,500 feet in diameter, with a final depth of 1,800 to 2,900 feet, depending on the elevation of the pit rim. The mine would produce a total of 550 million tons of ore and 1.3 billion tons of waste rock. Highway access would be from State Route 83, which connects to Interstate 10 approximately 12 miles north of the mine site. A new two-lane gravel road would be constructed to provide access between State Route 83 and the mine. The project would be located primarily within the Barrel Canyon drainage and its tributaries. Diversion channels would be constructed to intercept runoff from precipitation and route it around the mine facilities for discharge to lower Barrel Canyon, downstream of the project. The project would use 5,000 acre-feet per year of fresh water, for a total over the mine life of approximately 100,000 acre-feet. The water would be pumped from four to six wells located on land owned or leased by Rosemont Copper near the community of Sahuarita in the Santa Cruz Valley and would be piped to the mine. Six alternatives, including a No Action Alternative (Alternative 1) and the proposed action (Alternative 2), are considered in this draft EIS. Under the preferred Barrel Alternative (Alternative 4), all tailings and waste rock would be placed in Upper Barrel and Wasp Canyons. Two water line alignments and five alternative routes for an aboveground 138-kilovolt transmission line and an associated 14-foot-wide unpaved maintenance road are considered. POSITIVE IMPACTS: Implementation would allow development of the Rosemont ore deposit in a manner that complies with Federal, State, and local laws and regulations. Production estimates include 234 million pounds of copper, 4.5 million pounds of molybdenum, and 2.7 million ounces of silver annually over 20 years. The preferred alternative would avoid placement of mine waste in McCleary Canyon, thus preserving resource values, including recreation, riparian areas, and wildlife habitat. NEGATIVE IMPACTS: The preferred alternative would result in the loss of 39.9 acres of jurisdictional waters of the United States, the conversion of 7,014 to 7,095 acres of habitat, and potential impacts on up to 145,190 acres. Wildlife species impacted would include nine species federally listed as threatened or endangered. All of the action alternatives may result in a loss of population viability for two special status plant species. Numerous prehistoric and historic sites would be impacted. Modeling indicates that remnant heap leach seepage would exceed aquifer water quality standards for cadmium, nickel, and selenium. However, the heap leach facility would be located on top of a stable rock location and designed to collect all possible drainage and solution. Potential grazing activities would be reduced by 1,075 animal unit months. Blasting and equipment operational noise would result in a likely decrease in recreational value in the area. Long-term adverse impacts on astronomy would affect research at Whipple Observatory and Jarnac Observatory.

The mine life, including construction, operation, reclamation, and closure, would be approximately 25 years. Associated infrastructure would consist of haul and access roads, ore transportation systems, ore processing facilities, waste rock and tailings areas, leach facilities, electrical and water transmission lines, and ancillary facilities integral to the operations, such as the administration building, employee change house, warehouse, analytical laboratory, vehicle servicing facilities, storage facilities, guard house, and truck scale. The roughly circular open-pit mine would measure, at end of mine life, between 6,000 and 6,500 feet in diameter, with a final depth of 1,800 to 2,900 feet, depending on the elevation of the pit rim. The mine would produce a total of 550 million tons of ore and 1.3 billion tons of waste rock. Highway access would be from State Route 83, which connects to Interstate 10 approximately 12 miles north of the mine site. A new two-lane gravel road would be constructed to provide access between State Route 83 and the mine. The project would be located primarily within the Barrel Canyon drainage and its tributaries. Diversion channels would be constructed to intercept runoff from precipitation and route it around the mine facilities for discharge to lower Barrel Canyon, downstream of the project. The project would use 5,000 acre-feet per year of fresh water, for a total over the mine life of approximately 100,000 acre-feet. The water would be pumped from four to six wells located on land owned or leased by Rosemont Copper near the community of Sahuarita in the Santa Cruz Valley and would be piped to the mine. Six alternatives, including a No Action Alternative (Alternative 1) and the proposed action (Alternative 2), are considered in this draft EIS. Under the preferred Barrel Alternative (Alternative 4), all tailings and waste rock would be placed in Upper Barrel and Wasp Canyons. Two water line alignments and five alternative routes for an aboveground 138-kilovolt transmission line and an associated 14-foot-wide unpaved maintenance road are considered. POSITIVE IMPACTS: Implementation would allow development of the Rosemont ore deposit in a manner that complies with Federal, State, and local laws and regulations. Production estimates include 234 million pounds of copper, 4.5 million pounds of molybdenum, and 2.7 million ounces of silver annually over 20 years. The preferred alternative would avoid placement of mine waste in McCleary Canyon, thus preserving resource values, including recreation, riparian areas, and wildlife habitat. NEGATIVE IMPACTS: The preferred alternative would result in the loss of 39.9 acres of jurisdictional waters of the United States, the conversion of 7,014 to 7,095 acres of habitat, and potential impacts on up to 145,190 acres. Wildlife species impacted would include nine species federally listed as threatened or endangered. All of the action alternatives may result in a loss of population viability for two special status plant species. Numerous prehistoric and historic sites would be impacted. Modeling indicates that remnant heap leach seepage would exceed aquifer water quality standards for cadmium, nickel, and selenium. However, the heap leach facility would be located on top of a stable rock location and designed to collect all possible drainage and solution. Potential grazing activities would be reduced by 1,075 animal unit months. Blasting and equipment operational noise would result in a likely decrease in recreational value in the area. Long-term adverse impacts on astronomy would affect research at Whipple Observatory and Jarnac Observatory.

Preparation date: October 21, 2011 N1 - Last updated - 2011-12-16 ER - TY - JOUR T1 - The Spitzer ice legacy; ice evolution from cores to protostars AN - 1464885477; 2013-094569 AB - Ices regulate much of the chemistry during star formation and account for up to 80% of the available oxygen and carbon. In this paper, we use the Spitzer c2d Legacy ice survey, complimented with data sets on ices in cloud cores and high-mass protostars, to determine standard ice abundances and to present a coherent picture of the evolution of ices during low- and high-mass star formation. The median ice composition H (sub 2) O:CO:CO (sub 2) :CH (sub 3) OH:NH (sub 3) :CH (sub 4) :XCN is 100:29:29:3:5:5:0.3 and 100:13:13:4:5:2:0.6 toward low- and high-mass protostars, respectively, and 100:31:38:4:-:-:- in cloud cores. In the low-mass sample, the ice abundances with respect to H (sub 2) O of CH (sub 4) , NH (sub 3) , and the component of CO (sub 2) mixed with H (sub 2) O typically vary by <25%, indicative of co-formation with H (sub 2) O. In contrast, some CO and CO (sub 2) ice components, XCN, and CH (sub 3) OH vary by factors 2-10 between the lower and upper quartile. The XCN band correlates with CO, consistent with its OCN (super -) identification. The origin(s) of the different levels of ice abundance variations are constrained by comparing ice inventories toward different types of protostars and background stars, through ice mapping, analysis of cloud-to-cloud variations, and ice (anti-)correlations. Based on the analysis, the first ice formation phase is driven by hydrogenation of atoms, which results in an H (sub 2) O-dominated ice. At later prestellar times, CO freezes out and variations in CO freezeout levels and the subsequent CO-based chemistry can explain most of the observed ice abundance variations. The last important ice evolution stage is thermal and UV processing around protostars, resulting in CO desorption, ice segregation, and the formation of complex organic molecules.

ID 141 was observed using the IRAM 30 m telescope and Plateau de Bure interferometer (PdBI), the Submillimeter Array, and the Atacama Pathfinder xperiment submillimeter telescope to measure the dust continuum and emission lines of the main isotope of carbon monoxide and carbon ([C I] and [C II]). The detection of strong CO emission lines with the PdBI confirms that ID 141 is at high redshift (z=4.243 + or - 0.001). The strength of the continuum and emission lines suggests that ID 141 is gravitationally lensed. The width (Delta V (sub FWHM) approximately 800 km s (super -1) ) and asymmetric profiles of the CO and carbon lines indicate orbital motion in a disk or a merger. The properties derived for ID 141 are compatible with an ultraluminous (L (sub FIR) approximately (8.5 + or - 0.3)X10 (super 13) mu (super -1) (sub L) L (sub []) , where mu (sub L) is the amplification factor), dense (n nearly equal 10 (super 4) cm (super -3) ), and warm (T (sub kin) nearly equal 40 K) starburst galaxy, with an estimated star formation rate of (0.7-1.7)X10 (super 4) mu (super -1) (sub L) M (sub []) yr (super -1) . The carbon emission lines indicate a dense (n nearly equal 10 (super 4) cm (super -3) ) photon-dominated region, illuminated by a far-UV radiation field a few thousand times more intense than that in our Galaxy. In conclusion, the physical properties of the high-z galaxy ID 141 are remarkably similar to those of local ultraluminous infrared galaxies. Copyright (Copyright) 2011.

The study points out similarities and differences of the systems in field experiments and data processing. The closed-path system, despite a less intrusive placement with the sonic anemometer, required more care and power. In contrast, the open-path system appears more versatile for a remote and unattended experimental site. Overall, the two systems have comparable minimum detectable limits, but synchronization between wind speed and methane data, air density corrections and spectral losses have different impacts on the computed flux covariances. For the closed-path analyzer, air density effects are less important, but the synchronization and spectral losses may represent a problem when fluxes are small or when an undersized pump is used. For the open-path analyzer air density corrections are greater, due to spectroscopy effects and the classic Webb-Pearman-Leuning correction. Comparison between the 30-min fluxes reveals good agreement in terms of magnitudes between open-path and closed-path flux systems. However, the scatter is large, as consequence of the intensive data processing which both systems require.

Changing climate, sea level rise, and shifting shorelines created ecological challenges for ancient coastal peoples and daunting challenges for archaeologists searching for early coastal sites. This paper reviews the evidence for ecological change in this 'West Coast' region, including shoreline changes that may have submerged or destroyed archaeological sites from this time period. Examining the regional record of human occupation dating to the Younger Dryas, well-dated coastal sites are limited to California's Northern Channel Islands and Isla Cedros off Baja California. A small number of fluted points found in coastal areas may also date to the Younger Dryas, but their context and chronology is not well defined. Review of the implications of these two data sets considers whether the early but discontinuous Younger Dryas archaeological record from the West Coast might result from a migration of maritime peoples from Northeast Asia into the Americas.

Coyotes (Canis latrans) have benefitted from anthropogenic changes to North American ecosystems and have experienced a dramatic range expansion since the early 19th century. The region east of the Mississippi River has been colonized via 2 routes that have converged in the mid-Atlantic region during the past few decades. Coyotes using the northern route of expansion show molecular evidence of admixture with the Great Lakes wolf (GLW). We used noninvasive molecular techniques to detect the geographic origins of the recent coyote colonization of northern Virginia as a representative of the mid-Atlantic region and to detect signatures of admixture with GLWs. Of 455 individual canid scats screened, we sequenced a variable 282-base pair fragment of the mitochondrial control region from 126 coyote scats, assigned individual identities to samples using 6 microsatellite loci, and conducted phylogeographic analyses by comparing our sequences to previously published haplotypes. In 39 individuals identified in our scat surveys we detected 7 mitochondrial DNA haplotypes, all of which have been previously reported in diverse surrounding geographic localities. Phylogeographic analyses indicate multiple sources of colonization of northern Virginia. One common haplotype detected in northern Virginia is of wolf origin, indicating the presence of admixed coyotes and GLWs from the north.

The settlements that have yielded the earliest record of eastern domesticates are all small and situated in resource-rich lower-order river valley corridors within oak-savannah and oak-hickory forest regions. Well-preserved floral and faunal assemblages indicate continued substantial reliance on a wide range of wild species with no evidence of resource depletion. Similarly, there is no indication of landscape packing in terms of high site density in these resource-rich river valleys, calling into question developmental models of domestication and agricultural origins that rely on population pressure or resource imbalance as causal factors.

As in other areas of the world, our understanding of this issue has been significantly advanced by a steady stream of archaeobotanical, paleoecological, and molecular/genetic data. Also importantly, a renewed focus on formulating testable theories and explanations for the transition from foraging to food production has led to applications from subdisciplines of ecology, economy, and evolution not previously applied to agricultural origins. Most recently, the integration of formerly separated disciplines, such as developmental and evolutionary biology, is causing reconsiderations of how novel phenotypes, including domesticated species, originate and the influence of artificial selection on the domestication process. It is becoming clear that the more interesting question may be the origins of plant cultivation rather than the origins of agriculture. This paper reviews this body of evidence and assesses current views about how and why domestication and plant food production arose. Adapted from the source document.

While in 1995 there appeared to have been at least a 1,500-year gap between plant and animal domestication, it now seems that both occurred at roughly the same time, with initial management of morphologically wild future plant and animal domesticates reaching back to at least 11,500 cal BP, if not earlier. A focus on the southern Levant as the core area for crop domestication and diffusion has been replaced by a more pluralistic view that sees domestication of various crops and livestock occurring, sometimes multiple times in the same species, across the entire region. Morphological change can no longer be held to be a leading-edge indicator of domestication. Instead, it appears that a long period of increasingly intensive human management preceded the manifestation of archaeologically detectable morphological change in managed crops and livestock. Agriculture in the Near East arose in the context of broad-based systematic human efforts at modifying local environments and biotic communities to encourage plant and animal resources of economic interest. This process took place across the entire Fertile Crescent during a period of dramatic post-Pleistocene climate and environmental change with considerable regional variation in the scope and intensity of these activities as well as in the range of resources being manipulated.

One of the principal characteristics of impact events is the formation and emplacement of ejecta deposits, an understanding of which is critical for planetary exploration. Current models of ejecta emplacement, however, do not account for several important observations of ejecta deposits on the terrestrial planets, in particular, the presence of more than one layer of ejecta. Furthermore, there is also no universal model for the origin and emplacement of ejecta on different planetary bodies. We present a unifying working hypothesis for the origin and emplacement of ejecta on the terrestrial planets, in which the ejecta are emplaced in a multi-stage process. The generation of the continuous ejecta blanket occurs during the excavation stage of cratering, via the conventional ballistic sedimentation and radial flow model. This is followed by the emplacement of more melt-rich, ground-hugging flows - the "surface melt flow" phase - during the terminal stages of crater excavation and the modification stage of crater formation. Minor fallback occurs during the final stages of crater formation. Several factors will affect the final morphology and character of ejecta deposits. The volatile content and cohesiveness of the uppermost target rocks will significantly affect the runout distance of the ballistically emplaced continuous ejecta blanket, with impact angle also influencing the overall geometry of the deposits (e.g., the production of the characteristic butterfly pattern seen in very oblique impacts). Ejecta deposited during the surface melt flow stage is influenced by several factors, most importantly planetary gravity, surface temperature, and the physical properties of the target rocks. Topography and angle of impact play important roles in determining the final distribution of surface melt flow ejecta deposits with respect to the source crater. This working hypothesis of ballistic sedimentation and surface melt flow provides a framework in which observations of ejecta at impact craters can be compared and placed in the context of the respective terrestrial planets.

Amphibians are currently suffering devastating declines and extinctions in nearly all parts of the world due to the emerging infectious disease chytridiomycosis caused by the chytrid fungus, Batrachochytrium dendrobatidis. Because chytridiomycosis is a skin infection and remains confined to the skin, immune defenses of the skin are critical for survival. Skin defenses include secreted antimicrobial peptides and immunoglobulins as well as antifungal metabolites produced by symbiotic skin bacteria. Low temperatures, toxic chemicals, and stress inhibit the immune system and may impair natural defenses against B. dendrobatidis. Tadpoles' mouth parts can be infected by B. dendrobatidis. Damage to the mouth parts can impair growth, and the affected tadpoles maintain the pathogen in the environment even when adults have dispersed. Newly metamorphosing frogs appear to be especially vulnerable to infection and to the lethal effects of this pathogen because the immune system undergoes a dramatic reorganization at metamorphosis, and postmetamorphic defenses are not yet mature. Here we review our current understanding of amphibian immune defenses against B. dendrobatidis and the ability of the pathogen to resist those defenses. We also briefly review what is known about the impacts of temperature, environmental chemicals, and stress on the host-pathogen interactions and suggest future directions for research.

Micrograins and discrete grains of CGM show a wide range of Mn/(Mn + Fe) values, but only the micrograins have limited Ta/(Ta + Nb) values. Trace amounts of Ti, Sc, Fe (super 3+) and Sn are common in both generations of CGM, but their total rarely exceeds 1.0 oxide wt%. The chemistry of the host cassiterite is relatively homogeneous and pure; the total concentration of FeO, MnO, Nb (sub 2) O (sub 5) , Ta (sub 2) O (sub 5) and TiO (sub 2) rarely exceeds 2.0 wt%. While discrete CGM grains show weak progressive zonation and minor replacement, micrograins display complex oscillatory zonation, resorption and/or replacement textures. Textural evidence suggests that the micrograins crystallized after the formation of discrete grains of columbite and cassiterite. On the whole, both discrete crystals and micrograins of CGM show increasing Mn/(Mn + Fe) with fractionation as commonly observed in F-enriched granitic pegmatites. Micrograins of CGM typically show higher Ta/(Ta + Nb) values compared to their discrete crystal counterparts. Textural characteristics of CGM micrograins are inconsistent with an origin by exsolution, and instead, indicate primary precipitation.

The sustainability of these plants is therefore of paramount importance. This paper analyses the market conditions for marama bean (Tylosema esculentum) products, taking into account economic, social and cultural conditions. Information on local livelihoods was gathered through focus groups and in-depth interviews with key informants in Botswana, South Africa and Namibia. The market analysis for marama products was conducted using an STP (segment, target, position) framework, and willingness to pay for prototype products was evaluated using the contingent valuation method to analyse structured questionnaires directed at retail outlets. The study found that assuring the sustainability of local people's livelihoods while creating a larger market is only achievable through community organisations supported by a broad marketing strategy and using cultivated marama.

What stands out, but is seldom noted, is that this occurred within democracies where the relative losers-the overwhelming majority-could in principle have used the political system to block or reverse rising inequality. Why did they not do so? A glance at history reveals that peoples have only very infrequently contested inequality because they were led to believe that their inferior status in terms of income, wealth, and privilege was just, that it was not really so bad, or that it was necessary for their future well-being. Ideological systems legitimated a status quo of inequality, or in more modern times even increasing inequality. This article surveys the manner in which inequality has been historically legitimated, first predominantly by religion, then predominately by economic thought. Attention is then focused on the manner in which contemporary economic science and its popular interpretations in the media have served to legitimate inequality in the U.S. since the mid-1970s. The article concludes with a reflection on the unique conditions that enable the legitimation of inequality to be delegitimated.

The Heterodyne Instrument for the Far-Infrared on board the Herschel Space Observatory has detected emission lines from both spin isomers of cold water vapor from the disk around the young star TW Hydrae. This water vapor likely originates from ice-coated solids near the disk surface, hinting at a water ice reservoir equivalent to several thousand Earth oceans in mass. The water's ortho-to-para ratio falls well below that of solar system comets, suggesting that comets contain heterogeneous ice mixtures collected across the entire solar nebula during the early stages of planetary birth.

To anticipate and adapt to these changes, it is necessary to understand their individual and aggregate impacts on forest growth and composition. We conducted a simulation experiment to evaluate regional forest change in Massachusetts, USA over the next 50 years (2010-2060). Our objective was to estimate, assuming a linear continuation of recent trends, the relative and interactive influence of continued growth and succession, climate change, forest conversion to developed uses, and timber harvest on live aboveground biomass (AGB) and tree species composition. We examined 20 years of land use records in relation to social and biophysical explanatory variables and used regression trees to create "probability-of-conversion" and "probability-of-harvest" zones. We incorporated this information into a spatially interactive forest landscape simulator to examine forest dynamics as they were affected by land use and climate change. We conducted simulations in a full-factorial design and found that continued forest growth and succession had the largest effect on AGB, increasing stores from 181.83 Tg to 309.56 Tg over 50 years. The increase varied from 49% to 112% depending on the ecoregion within the state. Compared to simulations with no climate or land use, forest conversion reduced gains in AGB by 23.18 Tg (or 18%) over 50 years. Timber harvests reduced gains in AGB by 5.23 Tg (4%). Climate change (temperature and precipitation) increased gains in AGB by 17.3 Tg (13.5%). Pinus strobus and Acer rubrum were ranked first and second, respectively, in terms of total AGB throughout all simulations. Climate change reinforced the dominance of those two species. Timber harvest reduced Quercus rubra from 10.8% to 9.4% of total AGB, but otherwise had little effect on composition. Forest conversion was generally indiscriminate in terms of species removal. Under the naive assumption that future land use patterns will resemble the recent past, we conclude that continued forest growth and recovery will be the dominant mechanism driving forest dynamics over the next 50 years, and that while climate change may enhance growth rates, this will be more than offset by land use, primarily forest conversion to developed uses.

AN - 904490345; 15690415 AB - We conducted a phylogeographic analysis of the strictly aquatic and critically endangered Central American river turtle, Dermatemys mawii, as part of a conservation management program for the species. We sampled 238 individuals from 15 different localities throughout the species range. Using sequence fragments from the mtDNA Cyt b and ND4 genes, we identified 16 different haplotypes. Overall, our results reveal a signal of phylogeographic structure throughout the range, which appears to have been secondarily blurred by extensive gene flow. Notably, this also applies to genetic structuring across three major hydrological basins that pose biogeographic breaks in other aquatic taxa. Divergence times of mtDNA haplotypes in D. mawii suggest that the main lineages split in the Pliocene-Pleistocene (3.73-0.227 MA) and demographic tests indicate that the species has undergone drastic demographic size fluctuations since this time period. One ancient haplotype (1D) was found to exhibit sequence divergence of up to 2% from other haplogroups. Divergence of this magnitude is indicative of species level differentiation in other turtle genera. Haplotype 1D was found in only two localities, Sarstun and Salinas, but specimens with other haplotypes were also found in those localities. It is not known whether the individuals with the 1D haplotype interbreed with non-1D individuals. Our results suggest that human activity, such as harvesting and long distance transport of animals, may have influenced the current patterns of genetic diversity. For more than 2000 years, D. mawii has been consumed by people from Middle American cultures, and the archeological record contains strong evidence that the Mayans transported animals between villages and far away from their natural distribution range. Therefore, the large-scale pattern of haplotype sharing even across hydrological barriers, the observed low haplotype diversity in some populations and the contemporary absence of a pronounced phylogeographic pattern is likely due to a combination of population expansions, gene flow, extensive human-mediated-movements and recent bottlenecks resulting from over-harvesting.

The genus Tubulogenerina was originally thought to have originated in Europe in the early Eocene. Our discovery of T. turonica indicates that the roots of the genus reach back to the middle Cretaceous and argues against a previous conclusion that it originated in temperate European regions. A tropical/subtropical site of origination would be consistent with the observation that most Tubulogenerina species inhabited warm, shallow-water environments. Tubulogenerina turonica has a relatively simple morphology, suitable as a starting point for morphological trends in the genus during the Cenozoic, thus supporting its status as a plausible ancestral species. In clay-rich middle Cretaceous sediments from Tanzania, foraminifera are exceptionally well preserved, and assemblages include a number of aragonitic taxa, including Colomia africana. This new species is distinguished from others of the genus by its aperture and toothplate structure and its dominantly biserial test without a well-developed uniserial growth stage. Morphologic similarities, however, indicate the close evolutionary relationship with other species of Colomia, so the genus is emended accordingly. Sufficient numbers of C. africana were found in multiple samples to characterize its stable carbon and oxygen isotope values relative to another aragonitic species (Epistomina chapmani) and calcitic species (Berthelina berthelini) from the same material. Results show an expected offset between calcitic and aragonitic tests that is partially explained by differential fractionation factors, but suggests vital or microhabitat effects contribute to values measured on C. africana.

The Adiantum pedatum complex has such a disjunct distribution. The monophyly of the complex needs to be tested and diversification history of the four species needs to be reconstructed. Methods: Plastid (atpA, atpB, rbcL, trnL-F, and rps4-trnS) sequences of 100 accessions representing the biogeographic diversity of Adiantum were analyzed with parsimony and Bayesian inference. Biogeography of the Adiantum pedatum complex was inferred using programs DIVA and LAGRANGE. Divergence times of clades were estimated with the program BEAST. Key results: The A. pedatum complex is monophyletic and sister to the eastern Asian A. edentulum. Accessions of A. pedatum do not form a clade; instead three subgroups are recognizable. The clade of A. aleuticum and A. viridimontanum is nested within A. pedatum. The Asian A. myriosorum is sister to the A. pedatum-A. aleuticum clade. Both DIVA and LAGRANGE analyses suggest an eastern Asian origin of the A. pedatum complex. The age of the crown A. pedatum complex is dated to be at 4.27 (2.24-6.57) million years ago. Conclusions: The currently recognized eastern Asian-North American disjunct species A. pedatum needs to be segregated into three species, corresponding to populations in eastern North America, China, and Japan. The eastern Asian-North American disjunction in the complex is inferred to be the result of two intercontinental migrations, one from eastern Asia into North America in the late Tertiary and the other from North America back to eastern Asia in the Pleistocene.

Furthermore, previous evidence suggests that non-indigenous species introduced via hull fouling may be capable of adapting to metal-polluted environments. Using a laboratory based toxicity assay, we investigated tolerance to copper in the non-indigenous bryozoan Watersipora subtorquata from four source populations. Individual colonies were collected from four sites within Port Hacking (Sydney, Australia) and their offspring exposed to a range of copper concentrations. This approach, using a full-sib, split-family design, tests for a genotype by environment (GE) interaction. Settlement and complete metamorphosis (recruitment) were measured as ecologically relevant endpoints. Larval sizes were also measured for each colony. Successful recruitment was significantly reduced by the highest copper concentration of 80 mu gL-1. While there was no difference in pollution tolerance between sites, there was a significant GE interaction, with large variation in the response of colony offspring within sites. Larval size differed significantly both between sites and between colonies and was positively correlated with tolerance. The high level of variation in copper tolerance between colonies suggests that there is considerable potential within populations to adapt to elevated copper levels, as tolerance is a heritable trait. Also, colonies that produce large larvae are more tolerant to copper, suggesting that tolerance may be a direct consequence of larger size.

Our study examines inter-species variation in stable isotopic values and their relation to the shell carbonate geochemistry and preservation by applying a combination of light-microscope and SEM imaging with microprobe and cathodoluminescence-based geochemical analyses. Our goal is to evaluate which species are best suited for studies of stable isotopes and temperature reconstructions in the Cretaceous. We present results from a Turonian sequence with relatively stable environmental conditions as inferred from minimal variation in intra-specific d (super 13) C and d (super 18) O values across the section. The studied material contains abundant and diverse benthic foraminifer assemblages that indicate an outer shelf to upper slope paleodepth. We performed single species d (super 13) C and d (super 18) O measurements for 18 calcareous benthic and 10 planktic species. Cross plots of d (super 13) C and d (super 18) O show distinct offsets between clusters of data points for individual species, reflecting a combination of differences in habitat and disequilibrium fractionation due to metabolic effects or an infaunal mode of life. Offsets in d (super 18) O between two groups of trochospiral planktic foraminifera apparently reflect water depth-related differences in temperature during their lifetime. An expected offset is observed between benthic species with aragonitic versus calcitic tests, but systematic offsets among aragonitic species indicate that micro-habitat or vital effects also influence measured values. The lowest d (super 13) C values among the calcitic benthic foraminifera were observed for species of the genus Lenticulina. Because we did not observe differences in their preservation relative to other benthic species, the isotope results suggest a strong influence of metabolic effects on isotopic fractionation for Lenticulina species. Among the calcitic benthic species studied the two species Berthelina berthelini and Lingulogavelinella convexa appear to have close-to-equilibrium values and are preferred for paleoenvironmental reconstructions.

Some indices, such as the Chemical Index of Alteration without Potash (CIA-K), have been used to estimate paleoprecipitation in paleosols. However, this relationship has only been established for temperate climates with mean annual precipitation (MAP) 1500 mm/yr, we sampled a series of modern soils along a strong rainfall gradient (1400-3500 mm/year) in the Republic of Panama. The soils supported undisturbed forests and were developed on basalts of similar geochemical composition. At each site, we collected samples to a maximum of 120 cm depth from duplicate profiles on local summits. Major and trace (Ti, Zr, Nb) element concentrations were measured as oxides by X-ray fluorescence. Modern mean annual precipitation was not correlated significantly with CIA-K (R (super 2) = 0.26), but was correlated strongly with Al (sub 2) O (sub 3) /(Al (sub 2) O (sub 3) +TiO (sub 2) ) (R (super 2) =0.59, p<0.01). When these relationships were applied to a series of 15 paleosols from a Paleocene-Eocene section in the Bogota Basin, Colombia, the estimated range in MAP was 1231-1559 mm/yr based on CIA-K and 2600-3139 mm/yr based on Al (sub 2) O (sub 3) and TiO (sub 2) . The latter is more reasonable given the calibration to high MAP, the tropical paleolatitude of the samples (<5 degrees N), and other proxies indicating increased weathering across the Paleocene-Eocene boundary in the region. This new proxy will allow a more accurate estimation of paleo-precipitation from humid tropical paleosols.

However, SEM images of the primary type species for these genera are available only for Muricohedbergella and Archaeoglobigerina. As a consequence, the taxonomic relevance of some diagnostic characters such as the development of the wall ornamentation and the presence of imperforate peripheral bands have been variably interpreted among authors (i.e., Gandolfi, 1955; Broennimann & Brown, 1956; Pessagno, 1967; Robaszynski & Caron, 1984; Georgescu & Huber, 2007). Studies of planktonic foraminiferal assemblages from different localities at varies latitudes highlight the occurrence of widely diffuse morphotypes with ornamented walls showing variably developed muricae, pustules and oriented costellae, so that some of the diagnostic characters currently used to discriminate among genera appear inadequate. To perform this study we examined Santonian-Campanian samples collected from different localities as follows: central Pacific Ocean (ODP Leg 198, Hole 1210B), western Australian margin (ODP Leg 122, Hole 762C), coastal Tanzania (TDP Sites 23, 28, 32, 35), and central Italy (Bottaccione Section, Gubbio). Selected specimens from each locality were analyzed using an SEM to characterize the shell microstructure and wall texture. These features have been used to revise the current classification scheme and for reconstructing lineages of descendants based on stratophenetic observations. Combined geochemical analysis (cathodoluminescence, delta (super 18) O and delta (super 13) C) have been applied on selected specimens showing different preservation to estimate the diagenetic effects on the primary wall features and to identify a possible correlation between ornamentation and habitat selection. Preliminary results suggest that the ornamentation could represent an ecological adaptation, and therefore its importance as a diagnostic character at genus level should be revised.

Recent advances in stable isotopic depth-ecology and paleoceanographic application of Mid-Cretaceous planktonic Foraminifera AN - 1420518415; 2013-064594 AB - Stable oxygen and carbon analysis of fossil planktonic foraminifera has been and remains a key tool in surveying oceanographic properties in the geologic past. In particular, parallel analysis of surface- and deep-dwelling taxa from the same samples is used to infer vertical water-column structures through time. Significant assumptions, often implicit, in such studies are that the depth-related ecological distribution of extinct planktonic foraminifera is adequately known (via comparison with modern morphological counterparts, paleobiogeographic distributions, and/or isotopic ecological ranking), and that each taxonomic group occupied the same ecological position through time and serves as a "stationary" recorder of paleoenvironmental conditions at a particular depth. These views have recently been challenged by our multispecies isotopic studies for the uppermost Albian-middle Cenomanian of the western North Atlantic (Ando et al., 2009, 2010). We found that the relationships between the test morphology and paleoecology of ancient planktonic foraminifera do not parallel those seen in extant morphologically comparative taxa, implying that morphology is a poor predictor of the planktonic paleoecology. Further, across the Albian/Cenomanian boundary, some taxa underwent dramatic depth-habitat reorganization (i.e., rapid habitat changes from thermocline to mixed-layer and vice versa, without major speciation). Such dynamic changes in the ecological preferences within planktonic foraminiferal assemblages should be a primary consideration in paleoceanographic interpretation of stable isotope data. The key to documenting such evolutionary paleoecological dynamics is to maximally utilize the coeval fine, coccolith-rich fraction data. Noteworthy is the fact that our data (unpublished) support highly flexible ecological behavior of a simple Hedbergella species, and its wide purely paleoceanographic application in previous studies should be viewed with great caution.

These ejecta deposits are thought to form as the result of volatile interaction during the impact process - most likely from a subsurface reservoir (either ice or liquid). This interaction forms an ejecta layer that flows away from the crater and forms a cohesive deposit that may have a clearly defined steep margin (or rampart). Evidence of emplacement mechanism identified in visible images suggests that the processes involved in forming these craters includes flow deposition, ballistic emplacement, and/or modification of the surface by airburst. The results of these processes should also be evident in variations of thermophysical properties, particularly those related to particle size and packing density. Thermophysical variations have been used previously to identify low thermal inertia crater rays (likely due to small particle sizes) and to examine the processes that form these features. In addition, thermophysical variations related to debris flow have been previously identified on ice-related geomorphologies (e.g. lobate debris aprons). An initial survey of relatively fresh layered ejecta deposits on Mars suggests that variations in nighttime temperature recorded by the Thermal Emission Imaging System (THEMIS) are related to these impact processes. Low temperature materials (appearing dark in THEMIS nighttime infrared images) lie on top of the lobate ramparts: these apparently fine-grained deposits have morphologies that suggest ballistic emplacement. Clear evidence of flow-related processes are not identifiable in layered deposits, but some lobes exhibit thermophysical variations along the margins that may be related to emplacement processes. Additional complications include post-depositional modification of ejecta - ballistic facies are difficult to identify in thermal data at some craters, and this modification may be masking flow-related thermophysical variations within lobate deposits. Initial results suggest that coupled thermal and high-resolution image studies of layered crater deposits will prove valuable for understanding the role subsurface volatiles played in the formation of these craters on Mars.

This proposal was not accepted by the Subcommission on Cretaceous Stratigraphy because no corresponding microfossil or chemostratigraphic event was found associated with the L. tardefurcata datum and the geographic distribution of L. tardefurcata was considered to be too limited. Recent study of exceptionally well preserved planktonic foraminifera across Aptian/Albian boundary intervals (i.e., above the appearance of elliptical forms of the coccolithophore Prediscosphaera columnata) at several DSDP and ODP deep-sea sections in the Atlantic and Indian Ocean resolved major taxonomic and biostratigraphic discrepancies and documented dramatic changes in shell structure, ornamentation, and size at the level of a major species turnover. Detailed quantitative study of planktic foraminiferal assemblages from the Col de Pre-Guittard section, located in the Vocontian Basin, documents this same foraminiferal turnover at the Niveau Kilian organic rich bed. A major negative carbon isotope shift has also been documented at this level in the Pre-Guittard section and at several deep-sea sites in the North and South Atlantic Ocean. We propose that the base of the Albian Stage be placed at Pre-Guittard using globally identifiable criteria defined by the extinction of the planktonic foraminifer Paraticinella eubejaouaensis, which corresponds with a major negative carbon isotope excursion and is just below the first appearance of the planktonic foraminifer Microhedbergella minglobularis. The P. eubejaouaensis extinction occurs within the Hypocanthoplites jacobi ammonite zone, is about 42 m below the base of the L. tardefurcata ammonite zone, and is within the evolutionary transition from elliptical to circular forms of the nannofossil Prediscosphaera columnata.

Although this model has been substantiated by the discovery of abundant microbially-induced sedimentary structures in close association with Ediacaran fossils, it has not been tested using experimental taphonomic studies under controlled laboratory conditions. Using XPS and ESEM-EDS we demonstrate the generation of iron sulfides and localized concentrations of common aluminosilicate cations (Al, K, Fe and Mg), a composition that has been frequently documented in association both with Ediacaran and other examples of soft tissue preservation. Furthermore, microbial mats are demonstrated to prolong the taphonomic window allowing for soft-tissue molding, while directly affecting the fidelity of preservation. These experiments are the first to investigate tissue decay in association with microbial mats, and provide necessary experimental support for the microbial death mask model responsible for exceptional preservation in the Ediacaran.

Two previously adjacent seas were separated and two continents united driving climate and environmental change and giving rise to extinctions and the migration of plants and animals across both continents. Here we present a geological map of a previously not well mapped area of the Isthmus, the Kuna Yala region along the northern Caribbean coast of Panama. We find that the region can be divided into roughly 13 distinct geological zones, comprised of many of the elements of a classic ophiolite deep sea sediment complex, including pillow basalts, pillow basalts with intrusive dikes, and an underlying gabbroic complex. This map presented in both its English and Spanish versions is part of an educational outreach project sponsored by the Smithsonian Tropical Research Institute and the SENACYT in collaboration with University of St. Thomas and the University of Minnesota. The map is intended to provide a general geological overview of the Kuna Yala Region. It is based on a combination of various previously published documents on the general geology of the Darian of Panama and recent and more detailed geological mapping of the Kuna Yala conducted by a Smithsonian Institute expedition into the region in the fall of 2008. The Spanish version of this map is intended for distribution among remote indigenous communities in the Kuna Yala.

However, in the 1970's, a local fish farm industry was established in the Setiu Estuary and lagoon and has continued to grow and spread into the surrounding mangrove forests, which are being increasingly cleared. As a result of these fish farms, nutrients, antibiotics, pesticides, fish food and fish waste are being emptied into the wetland system, potentially putting a stress on the environment. We are using a multi-proxy approach (foraminifera, sediment grain-size, carbon and nitrogen isotopic ratios) to address the environmental effects of the fish farms. The current distribution of benthic foraminifera, closely related to variations in salinity, sediment grain-size and other variables related to the hydrodynamics of the region, has been documented and these data provide a baseline for monitoring future change in estuarine/lagoonal environments. Push coring adjacent to floating fish cages indicates that the substrate prior to the initiation of aquaculture was medium to coarse-grained sand whereas the substrate beneath the cages is currently organic-rich mud, as determine by loss on ignition, with little sand, suggesting that the fish cages are directly impacting sedimentation, organic matter flux, and oxygen demand. Side scan sonar data indicate that the muddy substrate extends up to 10s of meters from the cages. Preliminary carbon/nitrogen data exhibit distributional patterns that correlate with the distribution of the fish cage mud.

However, as (super 7) Be, (super 234) Th, (super 210) Pb have half lives of 53.3 days, 24.1 days, and 22.26 yr, respectively, their utility for the identification of hurricane events decreases with progressively older deposits. Foraminifera, on the other hand, can be preserved for geologically significant amounts of time. Here we 1) investigate whether recent hurricane and non-hurricane deposits can be discriminated using foraminiferal assemblages and 2) whether insights concerning mode of sediment transport and sediment provenance can be gained from foraminiferal data. Samples were collected from cores taken in a series of cruises off the Mississippi Delta in 2004, 2005, and 2007 which reoccupied three of the same stations two to three times in a transect trending southwest from Southwest Pass ( approximately 30m water depth) to the upper boundary of the Mississippi Canyon ( approximately 90m water depth). Eight cores were selected, one from each station in 2004 and 2005, and one from each of two stations in 2007, as well as five ponar surface samples along the transect in 2007. From these, two 20 mL foraminiferal samples were taken from each hurricane deposit from each core as well as two from the pre- and post-storm deposits, where available. Foraminifera contained in these deposits have been identified to the species level. ANOVAs performed on transformed abundances of some common taxa reveals that while the abundance of some species, such as Epistominella vitrea, are significantly different in storm versus non-storm deposits, others, such as Buliminella morgani, show little to no response. The specific taxa that are significantly different between storm versus non-storm deposits also seem to vary between stations, which is likely a function of depth. Further analyses will make inferences about the provenance of individual storm beds based on foraminiferal distribution data.

The event layers off the Mississippi Delta caused by the recent hurricanes Rita, Katrina and Ivan exhibit foraminiferal assemblages distinct from the non-event sediment that overlies and underlies them. The event layers are characterized by sparse foraminifera and a high relative abundance of Textularia earlandi and Ammonia tepida. This research evaluates whether the foraminiferal signature of hurricanes can be preserved over a multi-decadal time-scale (based on Pb-210 age determinations). Three kasten cores (approximately 2m in length) were collected in 2007 at depths of 59 m, 75 m, and 87 m on a transect between Southwest Pass and the Mississippi Canyon. X-radiographs showed less-defined hurricane units compared to post-Katrina cores, and these were used to determine sampling locations. Samples were also taken in 10-cm increments to determine if foraminiferal signatures revealed hurricane units were detectable by grain size. Preliminary research has yielded assemblages rich in foraminifera and dominated by Epistominella vitrea and Uvigerina peregrina. T. earlandi and A. tepida are in very low amounts. These observations suggest that the sedimentological and foraminiferal signature of hurricanes on the Mississippi River delta over a multi-decadal timescale may be present but significantly muted as a result of bioturbation.

These mineral coatings are frequently associated with bacterial communities, suggesting that microbial activity plays a role in the precipitation of Mn oxides (through the oxidation of Mn(II) compounds). Until now, the contribution of fungi to this Mn biomineralization process in caves has been largely overlooked. In our studies of several caves in Southern Appalachians, we cultured several species of Mn-oxidizing Ascomycete fungi . The cave systems include Rye Cove-Cox Ridge Cave and Daniel Boone Caverns in southwest Virginia and Carter Salt Peter Cave in east Tennessee, all located in the Ordovician Knox Dolomite unit. Sample locations were selected by the presence of a black or brownish black coating or biofilm coating the cave walls and floors, or growing on exogenous materials left in the cave by human and animal visitors (tape, socks, feces), and Mn oxidation was confirmed in the field using the leucoberbelin blue (LBB) assay, a colorless chemical compound that turns bright blue in the presence of Mn(III) or Mn(IV) compounds. Cultured fungal samples were analyzed by light microscopy as well as scanning and transmission electron microscopy. TEM imaging and EDS analysis has revealed that in several samples, Mn oxidation only occurs within the fungal hyphae cells, particularly along hyphae where new hyphal branches are forming. In other samples it appears to be forming crumped sheets surrounding the exterior of the hyphae. In one sample, fruiting bodies appear to be oxidizing in addition to the hyphae. Mn oxides in fungal spores have not been observed at this time in any samples. Mn oxides produced by fungal cultures are poorly crystalline and appear amorphous to laboratory-based X-ray sources. Interestingly, tentative crystallographic identifications by single crystal micro-X-ray diffraction indicate that buserite (a layered Mn oxide) is the dominant mineral present in a sample isolated from a biofilm in a stream in Carter Salt Peter Cave.

Current oil exploration focuses on areas with structural complexity and non-conventional reservoirs. The Umir formation is an effective regional seal in MMVB Petroleum System however, some of the recent new targets are located in the cross-stratified sandstones in the upper Umir. There is little known on this new reservoir in Central-Eastern MMVB because both of the complex structures and the presence of a large unconformity known as the Middle Magdalena Valley Unconformity (MMVU). Hence, the regional distribution of these oil-bearing sandstones is uncertain and exploratory risk is high. This research focuses on developing a biostratigraphic framework for the Maastrichtian Umir Formation using palynology. Palynology is the best micropaleontological proxy to be used because depositional conditions in Umir Formation favored the preservation of abundant terrestrial (pollen and spores) and marine palynomorphs (dinoflagellate cysts and acritarchs). Major biostratigraphic events will be used to develop regional correlations, improve geological models, reduce the exploratory risk and serve as a key tool for on-site, real-time biostratigraphic control of exploratory wells. The study area is located on the western side of the Los Andes syncline, in Central Eastern MMVB. Ninety-nine samples for palynological content were selected from four cores covering a stratigraphic thickness of 2990 feet. The samples were processed in the Colombian Petroleum Institute (ICP) and standard palynological analyses are being conducted at Louisiana State University (LSU). Thus far, the palynological assemblage is characterized by the occurrence of Echimonocolpites protofranciscoi, Proteacidites dehaani, Buttinia andreevi, Echitriporites trianguliformis, Echitriporites suescae, Bacumorphomonocolpites taussae, Syndemicolpites typicus, Tetradites umirensis, Ulmoideipites krempii and Monocolpites grandispiniger. Six levels with abundant dinocysts and foram linings, showing a marked marine influence, have been recorded as well. The excellent recovery of terrestrial and marine palynomorphs shows potential to find new biostratigraphic events for the Maastrichtian biostratigraphy of northern South America.

Furthermore, they appear to be largely absent in Cenozoic sediments from the Caribbean. Lingulid brachiopods are poorly recorded in the fossil record, because of their very low fossilization potential. While better preserved, terebratulid brachiopods are typically restricted to hardground environments, which are uncommon in the fossil record. Recent field collecting efforts have resulted in new records of both the genera Glottidia [Lingulidae] from the Miocene Gatun Formation and Tichosina [Terebratulidae] from the Oligocene Panama Formation, of central Panama. They represent the first fossil forms of both their genera recorded in Central America thus far. The fragmented distribution of Glottidia in the tertiary of east America is widely recognized. The occurrence of this genus in the Panamanian Miocene suggests that the stratigraphic gap between the Eocene and Pliocene is artificial. The traditional view about of the biogeographic history of Glottidia suggests that (a) the genus may have originated on the west coast of North or Central America before the late Eocene and subsequently migrated to Atlantic. In contrast, a range of biological evidence suggests that living Glottidia descended from a Mesozoic clade of lingulids in Europe, consistent with a west Tethyan origin for the genus. The record of Glottidia in Miocene sediments of Panama is consistent with the supposed migration through the Central America Seaway, although the direction of migration cannot be determined. The terebratulid brachiopod Tichosina is known from relatively few assemblages in the Oligocene through Recent of the Caribbean. This new occurrence in central Panama represents the most southern record of fossil Tichosina reported so far. The brachiopods were collected from volcaniclastic breccia and mass-emplaced sandstones, presumably reworked downslope from a cobble hardground. Both records represent not only important additions to the Tertiary marine fauna of Tropical America but also contribute to our understanding of the biogeographic history of tropical brachiopods. Could it be that Caribbean fossil brachiopods are far more common that present research suggests?

The taxonomy of these microfossils is based on shape and size of the operculum (an opening) being the highest hierarchical criterion--particularly in calcareous dinoflagellate cyst taxonomy. Wall crystal architecture is the second-most important criterion. We found evidence that these key-traits of taxonomic classification of Pithonelloideae are subject to spectacular re-crystallization during carbonate diagenesis. Here we show a comparison between pristine Pithonelloideae from material recovered by the Tanzanian Drilling Project with Pithonelloideae from the Chalk (northern France). The preservation-states of these two materials differ tremendously so that it is impossible that both represent the original bio-mineralogical wall-architecture equally. However, both have been used in detailed wall-crystallographic analyses resulting in taxonomic description. We find a gradual crystallographic transition from the "Tanzanian preservation" to the "chalk preservation". Importantly, opercula in the Tanzanian material are spectacularly well preserved as revealed by detailed SEM-study. These observations shed new light on species distinction resulting in "lumping" formerly separated species and revising the existing classification scheme. Furthermore, the exceptional preservation of the Tanzanian material allows for CL-spectral study and geochemical measurements that enable unprecedented insight into the paleoecology of the Pithonelloideae.

The marine invertebrate fauna of the Culebra Formation in central Panama provides an important window into the paleoenvironments, biogeography, and biodiversity of southern Central America during the early Miocene. This study integrates considerable new material (181 sites, approximately 4600 specimens) with historic collections (91 sites, approximately 4700 specimens) from the Culebra Formation to investigate the biogeographic affinities, biodiversity, and paleoenvironmental context of Panama's early Miocene marine fauna. Freshly exposed stratigraphy made during excavations associated with recent expansion of the Panama Canal permit high-resolution analysis of environmental changes within the stratigraphy of the Culebra Formation. The Culebra Formation accumulated through a major transgression and regression, during which sediments accumulated lagoonal, fringing reef, and shallow-water deltaic depositional environments. New collections from canal excavations also allow for the analysis of biodiversity in the Culebra Formation, at both the local (community) scale and in the context of other known faunas in the broader Atlantic and eastern Pacific. The Culebra Formation (254 species) is not as diverse as some early Miocene tropical faunas, but its fossil record is clearly skewed by size-related lithification and diagenetic biases. When compared to molluscan faunas in other areas in the tropical and temperate Americas, the Culebra Formation is shown to belong to a biotic province extending from northern Peru through northern South America, and the southern Caribbean. These results clearly indicate unobstructed communication of faunas through the Central American Seaway during the early Miocene.

We present compositional data of garnet and gahnite from the Capoeira 2, Boqueirao, Alto Mirador, and Carrascao Li-Be-Ta-Nb-bearing pegmatites from the Borborema Pegmatite Province, northeastern Brazil. Garnet from all four pegmatites represents a spessartine-almandine solid solution with minor amounts of pyrope and grossular (sps (sub 71-96) alm (sub 2.5-27) pyr (sub 1-1.4) grs (sub 0.4-0.5) ). In a plot of MnO+CaO vs. FeO+MgO (wt%) garnet from Alto Mirador pegmatite plot in the field of high-Mn garnet from Core and Replacement Zones of Li pegmatites. In contrast, garnet from Carrascao, Boqueirao, and Capoeira 2 pegmatites plot in the field of Mn-Fe garnets in Core and Replacement Zones of Li-poor pegmatites. Based on these relationships, the tendency of the pegmatites to contain Li mineralization should increase in the order Capoeira 2, Boqueirao, Carrascao, and Alto Mirador. However, the Boqueirao pegmatite, which falls in the field of Li-deficient pegmatites, has been mined for Li. In addition, studies of tourmaline, mica, feldspar, and Nb-tantalum group minerals indicates that Capoeira 2 is more evolved than Boqueirao. The composition of gahnite in pegmatites from the BPP (gah (sub 90-97) hc (sub 0.6-9) spl (sub 0-5) ) falls within the compositional field of spinels in pegmatites and in the field of gahnite from rare-element granitic pegmatites (LCT-type) from Ontario. Gahnite from the Alto Mirador pegmatite has two different populations of compositions, one of them containing the highest Mg and lowest Zn content of gahnite from all pegmatites analyzed, indicating that gahnite recorded a change from a less evolved to a more evolved system during crystallization. This suggests that our understanding of the compositional variations of garnet and gahnite in pegmatites and the relationship with the formation of Li mineralization may still be limited. The major element composition of these minerals may provide complementing, but sometimes contrasting information, and trace element compositions may be required to better understand the evolution of granitic pegmatites.

Accordingly, this Cambrian "explosion" has been the topic of extensive research: a multitude of contentious environmental, genetic, and ecological explanations have been proposed as primary causes or catalysts of this biological revolution. We present a new compilation of the patterns of fossil diversification in combination with new molecular clock results and comparative developmental data, and information on early ecological feeding strategies. These data demonstrate a macroevolutionary lag between the diversification of major metazoan clades and the establishment of their developmental toolkits in the Cryogenian, and their later ecological success in the Ediacaran and Cambrian. Focusing upon first fossil occurrences of the higher Linnean taxonomic rankings of phyla, classes and orders captures the origination pattern of major developmental innovation; the appearance of fossil phyla and classes is mirrored by new divergence time estimates for major clades and crown-groups, indicating robust, mutually-reinforcing fossil and molecular signals. We argue that the diversification of animals involved the establishment of new forms of developmental regulation, including novel controls on cellular differentiation, as well as innovations in networks of ecological interaction, all occurring within the context of permissive environmental conditions. The Cryogenian-Cambrian evolutionary lag illustrates the complex and potentially contingent nature of major evolutionary events, and highlights the importance of adopting a synthesis of developmental, ecological and environmental approaches to understanding the mechanisms driving an equally multifaceted Cambrian conundrum.

The quantification of distinct insect-mediated damage types (DT) on fossil leaf assemblages has revealed consistent, long-term patterns of DT richness (DTR) responding to biotic and abiotic disturbance. External feeding is the most abundant and diverse type of leaf damage in living and fossil forests; however, due to mouthpart convergence across various insect lineages, the relation between external-DTR and insect richness (IR) has remained unknown, restricting the use of external-DTR in describing past and extant herbivory. We explore the relation between leaf chewing insect species and external-feeding DTR in two lowland tropical forests in the Republic of Panama. Herbivorous insects feeding on the canopy of dominant plant species at each site were collected, and their induced DTs recorded. A robust, positive correlation between IR and external-DTR was found across host plants at both sites, linking the number of insect species on a host species to the number of recorded external-DTs. External-DT turnover across plant hosts was found to follow insect species turnover, suggesting that herbivore assemblages are to some extent reflected in external-feeding DT composition in living forests. DTs recorded by multiple insect species in Panama are also the most abundant in two South American Paleogene floras, indicating that abundant DTs in fossil floras may underestimate the number of culprit insects. External DT composition is quantifiable in living and fossil forests, and is promising for insect herbivore turnover across host plant species. These findings validate underlying assumptions in fossil-based interpretations of DTR and suggest that external DTR, when used in combination with endophagous and specialized feeding traces (known to represent single insect species on single host species), can be a robust proxy for tracking relative (not absolute) changes in insect richness in the fossil record.

This Tethyan carbonate platform preserves a relatively complete stratigraphic record through the interval, as indicated by biostratigraphy and new carbon isotope data, and also provides a clear imprint of sea level fluctuation as evidenced in sedimentologic structures and geochemistry (e.g., wt. % CaCO (sub 3) ). Application of the Average Spectral Misfit method for astrochronologic testing (Meyers and Sageman, 2007) to wt. % CaCO (sub 3) data confirms orbital influence on sedimentation through the OAE 2 interval, where data resolution is sufficient to resolve precession, obliquity and eccentricity components. This analysis also reveals a strong 1.2 Ma rhythm in wt. % CaCO (sub 3) and delta (super 13) C data, which demarcates the "3 (super rd) -order" sequence boundaries immediately above and below the C/T boundary, and is consistent with a long-period obliquity influence on sea level and the carbon cycle. "Minimal tuning" exercises provide additional evidence to support the presence of a pervasive 1.2 Ma pacing for all five sequence boundaries present in the section, in each case coupled to a 1.2 Ma cycle in the delta (super 13) C data. In the Oligocene, a 1.2 Ma obliquity cycle has been shown to be related to carbon cycle events, 3 (super rd) -order sea level fluctuations and glacial periodicity. We consider possible drivers for this long-period linkage between orbital cycles, sea level, and the carbon cycle during the Cretaceous greenhouse, a time during which continental ice sheets are expected to be either ephemeral or non-existent. Our mineralogic assemblage data from the Levant Platform indicates systematic changes in weathering patterns that are consistent with variable freshwater transport between the ocean and land, supporting the hypothesis that freshwater storage in aquifers played an important role in modulating eustacy.

In this paper we use orbital observations by NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft to examine the geological evolution of three young peak-ring basins on Mercury. Rachmaninoff (290 km in diameter), Raditladi (265 km), and Mozart (236 km) all contain smooth plains deposits within their interiors and pockets of what appear to be solidified impact melt atop their continuous ejecta deposits. Smooth plains material within Rachmaninoff's peak-ring appears, on the basis of crater size-frequency distributions and color contrasts, to be the result of volcanism that occurred well after the impact basin formed. Inside Rachmaninoff's rim is a bright diffuse deposit, similar to deposits elsewhere that have been interpreted to be of pyroclastic origin. Raditladi is one of the youngest basins on Mercury, with an age of perhaps only approximately 1 Gy. It is partially filled with smooth plains that are spectrally indistinct and not clearly different in age from the basin; whether these plains consist of impact melt or volcanic material emplaced shortly after basin formation is unclear. Mozart contains sufficient smooth plains to obscure more than half its peak ring. Despite apparent differences in age, relative volume, and perhaps origin of the materials filling the basins, all three contain sets of approximately concentric troughs in smooth plains within their central peak rings. Somewhat similar patterns of troughs are found within some ghost craters in Mercury's northern volcanic plains and in plains exterior to the Caloris basin, although these do not display the dominantly concentric patterns of the troughs within the three basins. Among models proposed for the formation of the troughs within the three peak-ring basins, the most promising is a combination of flexural stresses from the interior response to the formation of the basin and thermal stresses accumulated during cooling of plains material.

Associated with these deposits, referred to as northern smooth plains, are sets of volcanic and tectonic landforms not resolved in flyby images. Among these landforms are numerous impact structures flooded by plains lavas. At least 21 of these flooded craters and basins, with diameters ranging from approximately 40 to approximately 300 km, host extensional troughs of multiple orientations, many of which form polygonal patterns concentrated within the inner part of the buried crater. The localization of the troughs in flooded craters and their commonly polygonal patterns raise the question of whether these troughs originate from contraction of the cooling volcanic fill. Several flooded craters in the same size range are devoid of troughs, however, and measured extensional strains accommodated by troughs within craters that host them are at, or exceed, the upper limit on longitudinal contractional strain for plausible ranges of cooling. These observations suggest that trough formation is of tectonic origin or reflects a combination of tectonic and cooling stresses. This inference is seen best in the 300-km-diameter Goethe Basin, which, in its interior, contains two smaller buried impact craters of diameter 41 and 56 km. Across these craters, strain is more than twice as high as the average strain expressed across other buried trough-bearing craters, indicating that an increased thickness of the volcanic cover in these two craters, the result of lower pre-flooding elevations, correlates with amplified strains at the surface. Such fracturing behavior is consistent with an uplift origin for the troughs in the flooded craters, since uplift of thicker layers allows trough-bounding faults to propagate deeper and consequently increase their displacements, leading to higher strains at the surface. Moreover, analysis of the global distribution of these extensional terrains reveals that they occur in clusters in both the northern plains and on the plains exterior to the Caloris basin, implying that there is a spatial correlation to regional geologic setting or long-wavelength geophysical variations. Such relations provide insight into the deformational history of Mercury.

Identified evidence of extensional deformation was confined almost exclusively to impact basin floors. After the MESSENGER spacecraft was successfully inserted into orbit about Mercury in March 2011, imaging of the heretofore largely unexplored north polar region revealed a large expanse of smooth plains. Although these northern plains are deformed by contractional wrinkle ridges, MESSENGER orbital images show evidence of widespread extension. Narrow, linear, and curvilinear troughs, up to 1-2 km wide and approximately 15 km in length, are found in the smooth plains and are interpreted to be fractures and graben. Many of the graben form polygonal patterns similar to those found on the floors of the Caloris and Rembrandt basins. Graben in other areas of the northern plains tend to have preferred orientations rather than polygonal patterns. The graben are generally confined to plains areas partly or completely ringed by wrinkle ridges, interpreted as marking the rim crests of impact craters buried by lava flows. The diameters of these areas range from <100 km to 300 km in the Goethe basin. Crosscutting relations between graben, ridge rings, and other wrinkle ridges suggest that contraction predated extension of the plains material. Also, crosscutting relations between wrinkle ridges and ridge rings encompassing the buried basins suggests that ridge rings postdate other plains wrinkle ridges. Our interpretation of these relations is as follows. After burial of heavily cratered regional terrain by volcanic plains material, subsidence in response to plains loading led to the formation of wrinkle ridges and ridge rings. Ridge formation was followed by uplift and extension of the plains material, possibly due to continued isostatic response to earlier crater and basin formation or as a result of inward flow of lower crustal material. The crustal flow model adds a component of compressional stresses near the crater or basin rims as well as of extensional stresses in the crater or basin interiors. This later increment of compression could account for the observed crosscutting relations between plains wrinkle ridges and basin-encompassing ridge rings.

These data, taken under illumination and observation geometries optimized for observing both color and morphology, allow detailed co-mapping of geologic and spectral features across Mercury's surface. Impact craters that excavated material spectrally distinct from the surrounding pre-impact surface serve as windows into the subsurface, allowing observations of material at depth that would otherwise remain hidden to remote observations. Such craters provide insight into the stratigraphy of four of Mercury's younger large basins: Caloris (1550 km in diameter), Rembrandt (720 km), Beethoven (630 km), and Tolstoj (360 km). Spectrally distinct volcanic plains have flooded all of these basins. Post-flooding craters of varying sizes populate the basin interiors and enable an estimation of the thickness of the volcanic fill and the nature of the pre-flooding basin floor. Large craters in all four basins have excavated low-reflectance material (LRM) from beneath the volcanic fill, whereas small craters do not reveal spectrally distinct material. Typical LRM deposits have reflectance values as much as 30% below the global mean and likely constitute a compositional end-member. We use scaling laws and melt volume calculations to bound the depth of origin of the LRM ejecta and central peak structures. Preliminary estimates from MESSENGER flyby data indicated that the surficial volcanic material inside Caloris may be as thick as 2.5 to 4 km in regions and approximately 2 km near the center of Rembrandt. Higher-resolution orbital images of craters can be used to refine these estimates and map thicknesses across the basin interior. Comparisons with Rembrandt, Beethoven, and Tolstoj help us to interpret and understand the post-impact evolution of Mercury's younger large basins and to investigate further the extent and role of volcanism. Moreover, knowledge of the stratigraphy and volcanic fill inside these basins constrains models for their subsequent compensation, uplift, and deformation. Topography and gravity data link basin fill with the broader lithospheric evolution of Mercury.

Orbital data from the MESSENGER mission have affirmed earlier observations of an extensive area of smooth plains at high northern latitudes on Mercury; superposition relations and color data are consistent with a volcanic origin for these deposits. Few candidate vents and lava flow features have been identified, however, raising questions as to how these plains were emplaced, what volume of lava was erupted, and over what timescale volcanism occurred. We report on several channels proximal to the northern plains that cut through the surrounding intercrater terrain and strongly resemble surface flow feature observed on Earth and Mars. The channels exhibit braided textures and elongate, tapered "islands", characteristic of erosion by the above-ground movement of a low-viscosity fluid. One channel adjoins two rimless depressions that may have coalesced from smaller pits, and which we regard as candidates for volcanic vents. At the distal end of this same channel lies a peak-ring impact basin that has been flooded by lava. Parts of the inner peak ring protrude above the younger volcanic deposits, which in turn have been deformed by contractional wrinkle ridges. The pits, channel, and basin infill may therefore represent a complete extrusive volcanic system, from eruption to emplacement. Also of note is the suppressed topographic expression of the intercrater plains material nearby, possibly indicative of a veneer of lava that flowed overland outside of the well-defined channels. These findings suggest that Mercury's smooth plains were emplaced, at least in part, by discrete flows of low-viscosity lava. These flows may have exploited existing lineations formed by ejecta from nearby impact basins, such as secondary crater chains, reshaping them into the channels we observe today. We use the linear textures in the channels to determine flow directions and to place constraints on the local paleotopography, and we then calculate the volume of flooded terrain to provide a minimum value for the amount of material erupted in this area. Together with estimates of lava viscosity and the regional topographic gradient, these data constrain possible effusion rates, a parameter not yet readily measurable elsewhere on Mercury.

Mercury likely preserves a more complete record of early crustal formation than do Venus, Earth, or Mars, each of which experienced extensive and prolonged resurfacing and near-surface alteration since earliest crustal formation. The MErcury Surface, Space ENvironment, GEochemisty, and Ranging (MESSENGER) spacecraft, inserted into orbit about Mercury on 18 March 2011, carries a suite of instruments designed for elemental and mineralogical remote sensing. We report measured surface abundances of radioactive elements on Mercury and their implications for hypotheses regarding the planet's formation and thermal evolution. The average surface abundances of radioactive elements over the region of Mercury sampled by the Gamma-Ray Spectrometer are 1150 + or - 220 ppm K, 220 + or - 60 ppb Th, and 90 + or - 20 ppb U. Ratios of the moderately volatile incompatible element K to the refractory incompatible elements Th and U provide insights into the volatile inventory of planetary bodies. The measured K/Th ratio for Mercury (5200 + or - 1800) is comparable to values for the other terrestrial planets. By contrast, the lunar K/Th value (360) is an order of magnitude lower, indicative of the depletion of lunar volatiles relative to Earth. Mercury's K/Th ratio, combined with the high abundance of the volatile element sulfur measured by MESSENGER's X-Ray Spectrometer, indicates that the planet has a volatile inventory similar to those of the other terrestrial planets. Hypotheses proposed to explain the unusually high ratio of metal to silicate on Mercury also carry predictions for the ratios of volatile to refractory elements that can be tested against the K, Th and U abundances measured by MESSENGER. The abundance of the moderately volatile element K, relative to Th and U, is inconsistent with physical models for the formation of Mercury requiring extreme heating of the planet or its precursors and supports formation from relatively volatile-enriched material comparable to known chondritic meteorites. Abundances of K, Th, and U indicate that heat production declined substantially in the past 4 Gy, consistent with widespread volcanism near the end of late heavy bombardment and only limited volcanic activity since.

Thus, a major scientific objective of the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) mission, in orbit around Mercury since 18 March 2011, is to characterize the chemical composition of the planet's surface. We report the abundances of major rock-forming elements Mg, Al, Si, S, Ca, Ti, and Fe on the surface of Mercury, based on data acquired with the MESSENGER X-ray Spectrometer (XRS), which detects fluorescent 1 to 10 keV X-ray emissions that are excited by solar X-rays from within the top approximately 100 mu m of the regolith. The high solar X-ray flux during flares allows for detection of elements with atomic numbers up that of Fe. XRS data acquired during 10 solar flares indicate that the planet's surface differs in composition from those of other terrestrial planets. Mercury's Mg/Si, Al/Si, and Ca/Si ratios are intermediate between typical basaltic compositions and more ultramafic compositions comparable to terrestrial komatiites. These ratios rule out a lunar-like feldspar-rich crust. The sulfur abundance is at least 10 times higher (up to approximately 4 wt%) than that of the silicate portion of Earth or the Moon. Fe and Ti abundances are low, less than approximately 4 wt% and approximately 0.8 wt%, respectively. The observations support the view that Mercury formed from highly reduced precursor materials, perhaps akin to enstatite chondrite meteorites or anhydrous cometary dust particles. Low Fe and Ti abundances do not support the proposal that opaque oxides of these elements contribute substantially to Mercury's low and variable surface reflectance and indicate that other elements contribute to the relatively high degree of thermal neutron absorption observed on Mercury. The XRS data indicate compositional heterogeneity across the planet, although the large field of view for many of the observations makes direct correlation with identified geological units difficult. However, the highest Mg/Si, Ca/Si, and S/Si ratios are found in areas that include substantial amounts of low-reflectance material, supporting the possibility that sulfides contribute to the low reflectance.

Four campaigns being conducted during the first solar day (April-Sept. 2011) include low-Sun monochromatic mapping at an average resolution 0.21 km/pixel, to characterize morphology; high-Sun multispectral mapping at an average 1.0 km/pixel, to characterize spectral variations; repeated imaging of the south polar region at an average 1.5 km/pixel, to determine distribution of permanently shadowed regions and their relation with radar-bright deposits; and targeted, high-resolution imaging of key sites, in monochrome at an average 20 m/pixel and in color at an average 350 m/pixel. Monochrome mapping reveals a variety of landforms and stratigraphic relations that indicate volcanism over much of the planet, and in some locations multiple episodes. Extensional tectonic features are more widespread than recognized previously, with troughs typically arranged in concentric, radial, and more complex polygonal patterns in the medium-sized to larger, volcanically infilled impact basins. Newly recognized extensional features are troughs arranged in polygonal patterns in infilled craters with diameters from tens to a few hundred kilometers. Multispectral and high-resolution images of two types of rimless depressions suggest the importance of volatile phases in shaping Mercury's surface. Rimless depressions typically 10-40 km in diameter and surrounded by reddish haloes, interpreted as pyroclastic deposits, commonly exhibit evidence for multiple generations of activity. Distinctive smaller, rimless hollows hundreds of meters to a few kilometers in diameter occur on material exposed from depth in the later parts of Mercury's history; fresher-appearing hollows have a partial to complete halo of bluish deposits. To within uncertainties in map projection, permanently shadowed regions correlate with recognized radar-bright deposits around the south pole. During the second solar day MDIS will acquire a stereo complement to the monochrome map, determine south polar illumination at higher resolution of 0.3 km/pixel, and continue targeted imaging.

This can mask diversity dynamics by hiding the waxing and waning of subclades within the larger clade. The Carboniferous-Triassic members of the subfamily Knightininae offers a useful model: a small number of species are placed in the highly derived Knightites or Cymatospira, while most of the species are placed in the genus Retispira. The latter group of species includes some of the only known Triassic bellerophonts. Twenty-nine taxa of three genera, Retispira, Knightites, and Cymatospira, with stratigraphic ranges from the Lower Pennsylvanian to the Lower Triassic were analyzed based on specimens from collections and published literature. Minimum steps parsimony, stratocladistics and Bayesian methods were used to assess possible relationships. The resultant trees corroborate the monophyly of Knightites and Cymatospira, but also show multiple comparably rich subclades of Retispira species. At least two of these Retispira clades survived the P/T event, but 2-4 others did not. Retispira is only one of approximately fifty gastropod genera suspected of surviving the end-Permian, but in this one example, at least as many subclades went extinct as survived.

Because of its relatively low metamorphic grade, albite + epidote-bearing rocks of the IMVC preserve fluid-rock features related to process (1) that are now blurred by process (2) in other exposures of Late Triassic to Middle Jurassic metavolcanic rocks in the east central Sierra Nevada. We combined cathodoluminescence (CL) petrography and spectroscopy with whole-rock and mineral chemistry to characterize the petrogenesis of the two alteration phases in the IMVC and compare these with similar data for nearby, higher-T terranes. Abundances of Ce, Yb, Ta, and Th suggest shoshonitic affinities for the subaerial, arc flank rocks of the IMVC. However, major and trace element trends also suggest low-T alkali exchange through gain of K and Rb and loss of Na, Ca and Sr. Feldspar phenocrysts and matrix have been replaced by near-end-member K-feldspar and albite. CL images show multiple generations of K-feldspar not observed by back-scattered electron imaging or major element mineral mapping. Altered phenocrysts typically contain turbid, "brown"-CL K-feldspar. Such grains commonly preserve evidence of fracture-controlled growth. This early generation of altered feldspar is partially replaced by solid and fluid inclusion-poor, blue-CL K-feldspar along fractures and grain boundaries. Albite grains either display "brown" or red CL. Despite the marked differences in mineral types and compositions, not only are igneous textures mostly retained, but rare, relicts of igneous sanidine and intermediate plagioclase are preserved. "Brown"-CL emitting K-feldspar is typical of low-T, K metasomatized rocks. Two examples of terranes with higher-T, pluton related overprints, the Ritter Range and Alabama Hills, contain end-member K-feldspar that displays blue CL. Some of the Inyo Mountains rocks preserve K-feldspar textures that show a transition of CL-emission from brown to blue. These data indicate that fluid-mediated dissolution and reprecipitation create both low- and high-T feldspar replacement features in metavolcanic rocks of the Cordilleran Arc.

The interaction among insolation cycles and episodic tectonic effects is especially apparent in the paleoenvironmental records of the East African Rift System. A concise summary of key hypotheses linking African climate and evolution helps to define four criteria necessary in establishing cause-and-effect explanations of hominin evolutionary responses to environmental dynamics: (1) correlation; (2) associated biotic responses; (3) tested evolutionary mechanisms; and (4) analyses of hominin adaptations that point to the action of specific evolutionary mechanisms. Examples will show how these criteria are fulfilled relevant to variability selection explanations of the Plio-Pleistocene Oldowan expansion and the middle Pleistocene transition from Acheulean to Middle Stone Age. Especially relevant to these explanations is the framework of alternating high- and low-climate variability in tropical Africa, with key events in hominin evolution concentrated in the predicted longest intervals of high climate variability. A synthesis of environmental indicators cautions against an exclusive focus on the end members of environmental fluctuation (driest or wettest, warmest or coolest), and argues for the impact of the entire range of amplified variability in shaping evolutionary change. New theoretical modeling and simulations, furthermore, point to how adaptive versatility is selected as environmental variability is amplified. A relatively novel view thus emerges in which important changes in stone technology, life history, sociality, and other aspects of hominin behavior are understood as adaptive responses to heightened habitat instability. This research has been supported by the Smithsonian's Human Origins Program, the Peter Buck Fund for Human Origins Research, and the NSF HOMINID Program (BCS-0128511), with fieldwork permits and logistics supported by the National Museums of Kenya.

However, the advantage of rangeomorphs relative to competing osmotrophic prokaryotes has not been assessed. In a novel application, we use canopy flow models to reconstruct and parameterize flow in this community. Flow reconstructions are based on distribution and size of individuals on ash-fall preserved on event-bed surfaces as well as sedimentologic inferences of velocity. Three concepts of advantage provided by height off the substrate (conferred by multicellularity) are interrogated based on the flow modeling. The possible advantages of frond height include: 1) exposure to a mixed layer (composed of reductants from the bottom and oxidants from the water column) on the scale of the height of the community; 2) extension above a layer near the bottom depleted of a reactant-resource by the uptake activity of the community; 3) exposure to higher velocity which breaks down limits to uptake of reactants associated with the diffusive boundary layer at the surfaces of the organism. The modeling results strongly supports #3 to the exclusion of the other arguments. In this low-flow context access to "velocity" provides a critical advantage to longer forms extending into the water column. Thus the evolution of multicellular rangeomorphs appears to have been initiated as an adaptive response to diffusion limitation in a low-flow environment. Other groups that actively move fluid (such as sponges), are themselves motile, and/or ingest non-soluble resources then diversified forming Phanerozoic communities.

Significantly, the biota combines a classical Ordovician shelly fauna with both a large number of typical Early-Middle Cambrian Burgess Shale-type organisms and later, more derived unmineralized forms. Such co-occurrence indicates that replacement of Cambrian biotas during the Ordovician radiation was more protracted than hitherto recognized, and also suggests that significant diversification had already started well before the onset of the Tremadocian. These findings are further supported by a number of recent arthropod discoveries. One new arthropod of problematic affinity shows a thinly mineralized, strongly vaulted ovoid shield with a delicate dimpled ornament and a short, sharply delimited, annulated posterior axis. Another specimen belongs to Nektaspidida and exhibits a spatulate cephalic shield overlapping the first of three trunk tergites and a tail shield of comparable shape but smaller size. It most likely resolves within the family Liwiidae, reaffirming a Gondwana/Baltica affinity for this clade. An additional fossil may represent a badly preserved naraoiid. The discovery in the Fezouata Biota of the rare and poorly known arthropod genus Mollisonia marks the first occurrence of this taxon in the Ordovician, being previously known only from the Middle Cambrian of North America and China. Although overall very similar to Cambrian representatives of the genus, the detailed morphology of the Moroccan specimen differs from that of earlier forms. Importantly, the Fezouata specimen for the first time provides some information on the appendages of Mollisonia, with a pair of lamellate exopods and thin, probably cylindrical endopods being partially exposed to the left of the tail shield. Combined with its general morphology, this finding strongly suggests a position for Mollisonia within Lamellipedia. These recent arthropod discoveries reinforce the status of the Fezouata Biota as an intermediate in the evolution from Cambrian to later Paleozoic ecosystems.

These two processes are not independent from each other and, in the proper settings, can form negative feedback loops: degradation can create localized microenvironments facilitating authigenic mineralization which in turn limits degradation and promotes preservation. Such feedback loops are critical for exceptional preservation. The role of authigenic mineralization can be fulfilled by a variety of minerals (e.g. silica, phosphate, pyrite, and clay). A comparative taphonomic study of silicification, phosphatization, pyritization, and aluminosilicification shows that the nature of degradation, the timing and duration of mineralization, the size of authigenic minerals, and their diagenetic overgrowth and alteration, are factors that control the quality and taphonomic resolution of exceptional preservation. Fundamentally, regardless of the minerals involved, precipitation of authigenic minerals on degrading organic tissues, which serve as a physical template or a chemical substrate, is a key constructive process driving exceptional preservation. In this light, different styles of Burgess Shale-type carbonaceous compression (e.g., Burgess Shale vs. Chengjiang and Fezouata) can be viewed as examples of a singular taphonomic pathway fulfilled by different authigenic minerals (aluminosilicate vs. pyrite), and exceptionally preserved biotas that were previously regarded as representing distinct taphonomic modes (e.g., 2-D compression in Chengjiang and 3-D pyritization in Gaojiashan) can instead be viewed as end-members of a unifying mineralization model related by the nature and degree of authigenic mineralization. The unifying taphonomic model is supported by the intimate association of mineralization through silica, phosphate, pyrite, and clay in some exceptionally preserved biotas.

The Ediacara biota, consisting of stem group animals in addition to extinct higher-order clades, shifts to the familiar (and not so familiar) Cambrian and Paleozoic faunas. Although metazoans are demonstrably present in the Ediacaran, their ecological contribution is dwarfed by Ediacaran-type clades such as the Rangeomorpha and Erniettomorpha, while Ediacaran-type constructions such as fronds, flat-lying-recliners, mat-stickers, and mat-scratchers are virtually non-existent in younger assemblages. To evaluate the likelihood of a terminal Proterozoic mass-extinction, we explored temporal and biogeographic distributions of Ediacaran taxa combined with evaluations of morphospace ranges and ecosystem construction throughout the Ediacaran. The paucity of temporally-resolved localities with diverse Ediacaran assemblages, combined with difficulties associated with differences in taphonomic regimes before and after the transition hinders the evaluation of a proposed Ediacaran mass-extinction. However, the demonstration of geographic and morphometric range changes offers a novel means of assessing the downfall of Ediacara-type taxa at the hands of emerging metazoans. Ultimately, the combination of studies on morphospace occupation, ecosystem construction, biostratigraphy, and biogeography showcases the severity of the end Ediacaran extinction on the early evolution of macroscopic life.

The formation is often regarded as exemplar among diverse late Neogene Neotropical assemblages, and indeed is used as a baseline in studies investigating the effects of the closure of the Isthmus of Panama. A number of workers have undertaken exhaustive sampling of these macrofaunas, but none have attempted to understand the fine-scale spatial and temporal variations in the composition of the Gatun fauna High-resolution faunal inventories were conducted from over 700 stratigraphic horizons in the Gatun Formation, at more than 20 sections and boreholes in the Canal Basin of central Panama. Over 200 species were captured using this surveying approach, representing mostly widespread or common, and typically macroscopic species. This data permits quantitative paleoecological analyses of fossil assemblages through the stratigraphy of the Gatun Formation. Detrended correspondence analysis reveals a stratigraphic pattern of variation in the faunal composition of individual horizons as well as differences between sampling sites. In addition to their utility as tools of correlation between sections, curves of DCA axis scores provide a means to detect relative shifts in water depth and sedimentation through the stratigraphy and among localities. Overall the Gatun reveals both coarse- and fine-scale temporal variations in paleobathymetry, reflecting long-term shifts in basin subsidence and accommodation space that is potentially overprinted by fifth- or sixth-order glacio-eustatic cycles. Local species richness varies somewhat through the formation, being influenced by stratigraphic variation in the density of fossils and outcrop weathering. The high total diversity of the Gatun Formation is partly the result of excellent fossil preservation, extensive outcrops, and subtle turnover in species composition between assemblages.

Although much attention has focused on their geochemical and geochronological history, their relationship to each other and other major structures in the region is debated. Some geologic maps show Egrigoz and Koyunoba Plutons bounded to the west and separated from the Alacam body by the low-angle Simav detachment fault. In contrast, other regional maps show no offsets. To gain a better understanding of the exhumation history of the plutons, remotely-sensed images, geochronological data, geochemical analyses, and cathodoluminescence (CL) images were acquired to search for evidence of micro- to macro-scales of deformation. Numerous approximately E-W trending extension lineations parallel the Simav normal fault and cut the plutons. These lineations are due to large-scale approximately N-S extension that continues after their exhumation. In situ ion microprobe (super 238) U/ (super 206) Pb zircon ages of the granites range from 29.9 + or - 3.9 Ma to 14.6 + or - 2.6 Ma (+ or - 1s) and suggest the plutons crystallized over approximately 15 m.y. The dated zircons are located adjacent to or as inclusions in biotite, a relationship related to the crystallization history of the rocks. The majority of the reported compositions of these granites indicate they are magnesian, calc-alkalic and peraluminous granite to granodiorites. Geochemical analyses show little difference between the three plutons, consistent with the rocks arising from a similar source, likely a post-collisional volcanic-arc. CL images show that all samples experienced magma mixing, multiple episodes of brittle deformation, and fluid-mediated alteration. Instead of a single easily identifiable detachment working to exhume these granites, our results are consistent with a model where they exhumed via large-scale extension along multiple discrete normal faults.

Models of extant ecosystems hold that biodiversity is a buffer that helps stabilize ecosystem processes and services. When viewed over the entire Phanerozoic, modern levels of diversity and species richness are a relatively recent phenomenon in terrestrial communities. Many Mesozoic and older communities are considerably less diverse than those of today and yet demonstrate patterns of species composition, dominance and diversity patterns, and architectures that parallel those of modern ecosystems. Here, we analyzed one measure of community structure, the strength of species associations, in replicated plant and mammal communities from approximately 322 Ma to the present. Preliminary results indicate striking differences in the species associations of plants and mammals: on average, 60% of the associated pairs of fossil plant taxa showed positive associations through evolutionary time, whereas only 30% of associated mammal species pairs exhibited such associations. This result is particularly striking because the plant communities included in the analysis are very different taxonomically. In contrast mammal associations are considerably more variable and less positive through time. We investigated the variability in mammal communities further by analyzing the species associations of large mammal communities in Africa across the Plio-Pleistocene. We hypothesized that climate variability would affect species associations and predicted that during times of greater climate variability and therefore more patchily distributed resources, we would find stronger positive associations because species would be restricted to these isolated patchy resources. The trend is statistically significant (Spearman's rho = 0.825, p < 0.001) and suggests increasing provinciality (i.e., habitat tracking of increasingly patchy resources) in response to greater environmental variation. These null models suggest a fundamental difference in the community structure of plant and mammal communities.

We herein compare this record with the predictions of models of glacio-hydro-isostatic adjustment for St Croix and for additional sites at similar latitudes in the Greater and Lesser Antilles region. RSL predictions are based upon the model ICE-5G (VM2), and with a modified model ICE-6G (VM5A), both including and excluding the influence of rotational feedback. Misfits between the modeled sea levels and the local geologic data are most apparent for models without rotational feedback, particularly in the prediction of a +2 to +4 m unsupported mid-Holocene misfit at approximately 4 ka, as well as a small-amplitude highstand that extends from 2.5 to 1.5 ka. Incorporation of the influence of rotational feedback provides the best fit to the data, largely eliminating the unsupported mid-Holocene misfit between the data field and the sea-level histories predicted by the models without rotational feedback, and fitting data older than 5 kyr more closely than a previously published latitudinally-averaged sea-level curve for the western Atlantic. The St Croix data therefore demonstrate that rotational influence extends at least 27 degrees further south from its 45 degrees N mid-latitude extremum along the US east coast, and identifies tropical latitudes as influenced by proglacial forebulge collapse. Implications for reef-based sea-level reconstruction include the ability to accurately model sea levels at specific tropical sites with partial Holocene chronologies using the ICE-6G (VM5A) model with rotational feedback. Latitudinally-averaged sea-level curves are therefore of limited use in understanding the relative importance of contributing physical influences on postglacial sea-level history.

Terrestrial proxy records from mid to high northern latitudes suggest brief but intense warming across the Northern Hemisphere, but changes in the hydrologic cycle are controversial as paleoprecipitation estimates spanning the PETM vary widely. The Bogota Basin of Colombia preserves a 2 km conformable sequence of paleosols that offers an ideal setting to examine terrestrial climate change across the PETM in the paleotropics (paleolatitude <5 degrees N). However, existing paleoprecipitation proxies based on paleosols elemental ratios are calibrated only for temperate soils under mean annual precipitation <1500 mm. We examined the PETM in the Bogota Basin using the carbon isotope composition of bulk paleosol organic matter (n=80) to identify the CIE and the magnetic susceptibility and mineralogy of the paleosols to examine changes in weathering intensity associated with the PETM. Increased precipitation should intensify silicate weathering via hydrolysis reactions involving carbonic acid. For Fe-bearing silicate minerals, these reactions liberate Fe ions, which are often sequestered in Fe-oxides such as goethite and hematite. Increased precipitation could also enhance soil biological activity, increasing production of biogenic magnetite and maghemite. These Fe-oxides all have distinct magnetic properties that are easily measured and potentially can be used as proxies for changes in weathering and precipitation. Carbon isotopes reveal a CIE ( approximately -2ppm) in stratigraphic proximity to a tuff dated at 56.13 + or - 0.87 Ma. The same interval has a 100% increase in both susceptibility and concentrations of Fe-bearing magnetic minerals. We suggest that a sharp decrease in magnetic mineral concentration immediately after the CIE indicates decreased weathering and precipitation rates after the PETM. Our results suggest that chemical weathering in the tropics, as a proxy for the terrestrial hydrologic cycle, intensified in response to the onset of the PETM and decreased after its termination JF - Abstracts with Programs - Geological Society of America AU - Moron, Sara AU - Fox, David L AU - Feinberg, Joshua M AU - Bayona, German AU - Jaramillo, Carlos AU - Anonymous Y1 - 2011/10// PY - 2011 DA - October 2011 SP - 212 PB - Geological Society of America (GSA), Boulder, CO VL - 43 IS - 5 SN - 0016-7592, 0016-7592 KW - lower Eocene KW - isotopes KW - Eocene KW - isotope ratios KW - C-13/C-12 KW - paleomagnetism KW - Paleogene KW - Paleocene-Eocene Thermal Maximum KW - Colombia KW - paleoclimatology KW - stable isotopes KW - climate change KW - upper Paleocene KW - Cenozoic KW - Tertiary KW - South America KW - carbon KW - Paleocene KW - Bogota Basin KW - paleosols KW - stratigraphic boundary KW - 12:Stratigraphy KW - 02D:Isotope geochemistry UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1015462608?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Abstracts+with+Programs+-+Geological+Society+of+America&rft.atitle=Paleosol+carbon+isotope+stratigraphy+and+a+rock+magnetic+record+of+climate+change+across+the+Paleocene-Eocene+boundary+in+the+Bogota+Basin%2C+Colombia&rft.au=Moron%2C+Sara%3BFox%2C+David+L%3BFeinberg%2C+Joshua+M%3BBayona%2C+German%3BJaramillo%2C+Carlos%3BAnonymous&rft.aulast=Moron&rft.aufirst=Sara&rft.date=2011-10-01&rft.volume=43&rft.issue=5&rft.spage=212&rft.isbn=&rft.btitle=&rft.title=Abstracts+with+Programs+-+Geological+Society+of+America&rft.issn=00167592&rft_id=info:doi/ L2 - http://gsa.confex.com/gsa/2011AM/finalprogram/abstract_195492.htm LA - English DB - GeoRef N1 - Conference title - Geological Society of America, 2011 annual meeting N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

Primary data sources available for study are water well samples, two cores, driller logs, and two exposures. The predominantly subsurface structure truncates and disrupts Lower Ordovician and Cambrian strata to a depth of at least 200 m below the base of the widespread St. Peter Sandstone. Additional evidence supporting an impact origin for the structure includes: anomalous sub-shale stratigraphy including breccia containing clasts and matrix sourced from Lower Ordovician and Cambrian units; sparse exposures of deformed and brecciated target-rock (Shakopee Fm) adjacent to the projected crater rim; the presence of quartz grains in well cuttings and core that show planar microdeformation features (PMs) that resemble shock-produced planar fractures (PFs) or cleavage similar to those found at the Rock Elm impact structure, Wisconsin; and the presence of quartz grains displaying multiple intersecting sets of apparent planar deformation features (PDFs) like those typically associated with meteorite impact shock metamorphism. Preliminary measurement and documentation of PMs crystallographic rational indices has been accomplished and additional measurements are in progress. The majority of the wells in the structure penetrate less than 80 m below the Winneshiek Shale, but sample study from a few deeper wells support the following interpretations. The "Decorah Fault" appears to be a normal fault along the crater margin displaying over 100 m of offset, suggesting the presence of a down-dropped block. A deep well near the crater center produced cuttings with quartz pebbles similar to those of the deepest Paleozoic unit, the Mt. Simon Sandstone, suggesting disruption and uplift of the Mt. Simon. However, a sample and natural gamma log suggest that the Mt. Simon and overlying Eau Claire and Wonewoc formations are largely in place and at normal structural elevation. Additionally, we have not documented Precambrian crystalline rock fragments from any sample. This is problematic since an impact crater of such diameter would be expected to have disrupted some of the underlying basement.

These claims are not on equal empirical footing. Paleontologists have documented enough cases of within-lineage trait evolution to conclude that gradual, directional change over paleontological timescales is not common. Instead, most traits show meandering or oscillating change, consistent with stasis as broadly construed. The second claim, that changes are concentrated at speciation events, requires measurement of anagenetic and cladogenetic changes in a phylogenetic context. Far fewer fossil studies bear directly on this issue, though those by Cheetham and colleagues on the bryozoan genus Metrarabdotos are notable exceptions. Here I present a case study of similar scope and structure with an analysis of the deep-sea ostracode genus Poseidonamicus. Evolution is modeled with anagenetic, cladogenetic and (optionally) geographic components. Repeated samples within lineages, when coupled with a phylogenetic hypothesis for the clade, allow estimation of the separate contribution of these components. Simulations indicate that parameters of this model can be estimated successfully via maximum likelihood. Analysis completed thus far with data from Poseidonamicus indicate that parameter estimates can be sensitive to hypotheses about species limits and the nature of geographic variation. Nevertheless, these model fits are not consistent with purely cladogenetic change: for the shape features analyzed, the anagenetic component of change is always substantial.

Our approach combines a full radiative transfer calculation, retrieval algorithm, and trace gas climatologies to implicitly include the effects of albedo, clouds, ozone, and SO2 profiles in the retrieval. Under volcanic conditions, the algorithm may also be used to directly retrieve SO2 plume altitude. Retrieved SO2 columns over heavy anthropogenic pollution typically agree with those calculated using a two-step slant column and air mass factor approach to within 10%. Retrieval uncertainties are quantified for GOME-2 SO2 amounts; these are dominated by uncertainty contributions from noise, surface albedo, profile shape, correlations with other retrieved parameters, atmospheric temperature, choice of wavelength fitting window, and aerosols. When plume altitudes are also simultaneously retrieved, additional significant uncertainties result from uncertainties in the a priori altitude, the model's vertical layer resolution, and instrument calibration. Retrieved plume height information content is examined using the Mount Kasatochi volcanic plume on 9 August 2008. An a priori altitude of 10 km and uncertainty of 2 km produce degrees of freedom for signal of at least 0.9 for columns >30 Dobson units. GOME-2 estimates of surface SO2 are compared with in situ annual means over North America in 2008 from the Clear Air Status and Trends Network (CASTNET; r = 0.85, N = 65) and Air Quality System (AQS) and National Air Pollution Surveillance (NAPS; r = 0.40, N = 438) networks.

Of particular interest are methods that use bulk geochemistry to calculate a weathering index and, from that, mean annual precipitation. Twenty-three paleosols that formed during a time of significant climate change-the Paleocene-Eocene Thermal Maximum (PETM)-were analyzed to evaluate the relative merits of two geochemical proxies that have been developed for estimating paleoprecipitation: one depends on the chemical index of alteration without potash (CIA-K) and the other uses the CALMAG weathering index, which depends on CaO and MgO. The paleosols are located in the Paleogene Fort Union and Willwood formations in the Bighorn Basin, WY. Morphologic differences among the paleosols indicate that they formed under varied soil moisture conditions. A morphology index was developed from pedogenic features that are sensitive to soil drainage, and thus to rainfall, to assess that variability. Quantitative mean annual precipitation (MAP) values were calculated for each paleosol using the CIA-K index and the CALMAG index, which was developed specifically for Vertisols. Those results were compared to the morphology index for 23 paleosols. The results indicate that increases and decreases in MAP calculated from both methods correlate relatively well to changes in the soil morphology index; however, the results from the CALMAG weathering index show a stronger correlation. The results suggest that the CALMAG proxy provides a more robust MAP estimate for Vertisols. In addition to comparing MAP estimates to the soil morphology index, we compared the MAP values to paleorainfall estimates determined from paleofloras at the same stratigraphic levels as three of the paleosols. That comparison confirms that the CALMAG method is reliable for reconstructing MAP from ancient Vertisols. The results also show that, in the Bighorn Basin, Vertisols with a B horizon < 1m thick should not be used to determine MAP.

AN - 918053149; 15397472 AB - Agroforestry systems often receive attention and support in the literature for what is perceived as the benefits from multiple products associated with the trees that create the "forest" component of the setting. A comparison of small coffee growers' use of fruits derived from the coffee agroforestry holding in Guatemala and Peru reveals that significant differences exist between these groups-not merely in the importance of the fruits themselves, but in the ways they are used. The overall importance of fruits from the coffee system accounts for a relatively small portion of the total value coming from the coffee area (about 10%), but the consumption and sales of the various products do generate needed income or sustenance for most farmers. The fate of fruits shows significant differences between the two countries. Whether at the farm level or on a per hectare basis, Guatemalan coffee farmers are more linked into a market economy and sell significantly more fruits than Peruvian farmers. The opposite is the case when on-farm consumption (use value) of the fruits is compared. While the potential value of these products may be quite large (from 95 to 270/ha), we find that little gets consumed or sold, resulting in tremendous loss of potential benefits that could flow from these sources. Both groups lose more fruits than are sold or used, with Guatemalans foregoing more than three times the dollar value per hectare than Peruvians ( 151 / ha vs . 44/ha). Data about the economic context within which these growers and the fruits from coffee are found reveal possible reasons as to why we see the differences in use and exchange values realized in the two countries.

The depressions, or hollows, range from tens of meters to a few kilometers across, and many have high-reflectance interiors and halos. The host rocks, which are associated with crater central peaks, peak rings, floors, and walls, are interpreted to have been excavated from depth by the crater-forming process. The most likely formation mechanisms for the hollows involve recent loss of volatiles through some combination of sublimation, space weathering, outgassing, or pyroclastic volcanism. These features support the inference that Mercury's interior contains higher abundances of volatile materials than predicted by most scenarios for the formation of the solar system's innermost planet.

The abundance of the moderately volatile element K, relative to Th and U, is inconsistent with physical models for the formation of Mercury requiring extreme heating of the planet or its precursor materials and supports formation from volatile-containing material comparable to chondritic meteorites. Abundances of K, Th, and U indicate that internal heat production has declined substantially since Mercury's formation, consistent with widespread volcanism shortly after the end of late heavy bombardment 3.8 billion years ago and limited, isolated volcanic activity since.

Relatively high Mg/Si and low Al/Si and Ca/Si ratios rule out a lunarlike feldspar-rich crust. The sulfur abundance is at least 10 times higher than that of the silicate portion of Earth or the Moon, and this observation, together with a low surface Fe abundance, supports the view that Mercury formed from highly reduced precursor materials, perhaps akin to enstatite chondrite meteorites or anhydrous cometary dust particles. Low Fe and Ti abundances do not support the proposal that opaque oxides of these elements contribute substantially to Mercury's low and variable surface reflectance.

Gorgona Island, offshore western Colombia, is an accreted fragment of the CLIP, and its highly heterogeneous igneous suite, ranging from enriched basalts to depleted komatiites and picrites, was assumed to have formed at approximately 89 Ma from different part of the plume. Here we present new geologic, geochronologic and geochemical data of Gorgona with significant implications for the formation of the CLIP. A new set of (super 40) Ar- (super 39) Ar ages documents a magmatic activity spanning the whole Late Cretaceous (98.7 + or - 7.7 to 64.4 + or - 5 Ma) followed by a shallower, picritic pyroclastic eruption in the Paleocene. Trace element and isotope geochemistry confirm the existence of an enriched (EDMM: La/Sm (sub N) > or = 1 and epsilon Nd (sub i) of 5.7 to 7.8) and a depleted (DMM: La/Sm (sub N) 10%) of a mixed DMM + EDMM (40 to 60%) may reproduce the more depleted rocks with temperatures in the range of ambient mantle in the absence of plumes. Our results contradict the notion that the CLIP formed by melting of a plume head at approximately 90 Ma. Multiple magmatic pulses over several tens of Ma in small areas like Gorgona, also recognized in other CLIP areas, suggest a long period of diffuse magmatism without a clear pattern of migration. The age span of this magmatism is broadly concurrent with the Caribbean slab window. During this time span the Farallon oceanic lithosphere (later becoming the Caribbean plate) advanced eastward approximately 1500 km, overriding the astenosphere feeding the proto-Caribbean spreading ridge. This hotter mantle flowed westward into, and mixed with, the opening mantle wedge, promoting increasing melting with time. The fortuitous occurrence of a plume passing through the slab gap area cannot be excluded but not required to produce the observed composition and degree of melting.

Four taxa were identified through analyses of gut contents, and the index of relative importance suggested that amphipods, microphytobenthos and annelids are the most important food sources in the fish's diet. To assess the feeding habits of the fish after their recruitment to the IRL, these food sources were collected from mangroves and nearby seagrass beds for isotope analyses. Stable isotopes constituted a powerful tool for discriminating fish prey items from mangroves (mean +/-s.d. delta 13C = -20.5 +/- 0.6ppt) and those from seagrass beds (mean +/-s.d. delta 13C = -16.9 +/- 0.6ppt), thus providing good evidence of food source origins. The 56 M. punctatus collected [10.0 < total length (LT) < 16.2 cm] had average isotopic signatures of delta 13C = -16.7 +/- 0.2ppt and delta 15N = 8.2 +/- 0.1ppt. A significant depletion in 13C was observed for larger juveniles (15.0 < LT < 16.2 cm), suggesting that they found a portion of their food in mangroves. Estimation of the trophic level from stable isotopes (TLiso) was similar among different size groups of juvenile fish (TLiso = 3.2-3.5); therefore, M. punctatus was considered a secondary consumer, which is consistent with its zoobenthic diet. The concentration-dependent mixing Stable Isotope Analysis in R (SIAR) model revealed the importance of food sources from seagrass beds as carbon sources for all the fish collected, with a significant increase in mangrove prey contributions, such as annelids, in the diet of larger juveniles.

We developed primers that amplify two short Y-specific fragments (SRY1 and AMELY2) and one longer X-specific fragment (PLP1), developed from elephant sequences in one multiplex PCR. All fragments were designed to be short (<200 basepairs) for use with degraded DNA and to be 50 basepairs apart to optimize visualization on agarose gels or as electropherograms. The multiplex PCR method matched sexes for at least 97.9% of the noninvasive savannah elephant samples and produced the expected female/male banding patterns for 14 African forest and 11 Asian elephant samples. We found this method to be more robust, efficient and less prone to contamination than previously developed sexing methods for elephants.

This is the first documentation of the genus Apteribis from the island of Lanai and provides the only record of the nature of the plumage in any of the prehistorically extinct species of birds known from the Hawaiian Islands. Light and scanning electron microscope analyses of structure of the pennaceous and plumulaceous (downy) portions of these feathers confirmed their placement with the ibises (Threskiornithidae). Within that family, the microscopic structure of the downy feathers is most similar to that of the New World ibises of the genus Eudocimus, thus corroborating molecular evidence of the derivation of Apteribis from EUDOCIMUS: Plumage color was a combination of brown-black and ivory-beige/light brown suggestive of that of juveniles of Eudocimus. Plumage coloration in Apteribis may thus have evolved through the same processes of paedomorphosis that gave rise to flightlessness.

All three specimens originate from the Paracas Formation and their minimum age is constrained to about 37 Ma using (super 40) Ar/ (super 39) Ar dating of ash collected approximately 100 m up section from the source localities. Two new genera of archaeocete cetaceans are described along with additional material of another distinctive protocetid, which is not named pending the discovery of more complete material. Phylogenetic analysis resolves the two new genera within Basilosauridae, while the unnamed protocetid is closely related to Eocetus. The discovery of crownward protocetids in South America demonstrates that early cetaceans may have dispersed into both hemispheres prior to evolving a fully aquatic lifestyle. Geochronologic constraints on the age of new Peruvian archaeocetes establish them as the oldest whales from South America and among the oldest known from the Southern Hemisphere, which highlights the need for better sampling of marginal marine rocks from this part of the world.

AN - 885056285; 21593479 AB - Compared with the normospermic domestic cat, sperm metabolic function is compromised in the teratospermic cat and cheetah, but the pathway(s) involved in this deficiency are unknown. Glycolysis is essential for sperm motility, yet it appears to function normally in spermatozoa of either species regardless of structural morphology. We conducted a comparative study to further understand the mechanisms of energy production in felid spermatozoa, with the hypothesis that oxidative phosphorylation is required for normal sperm function and is impaired in teratospermic ejaculates. Electroejaculates from both species were stained with MitoTracker to quantify mitochondrial membrane potential (MMP) or were incubated to assess changes in sperm function (motility, acrosomal integrity, and lactate production) after mitochondrial inhibition with myxothiazol. Sperm midpiece dimensions also were quantified. Sperm mitochondrial fluorescence (directly proportional to MMP) was ~95% lower in the cheetah compared with the normospermic and teratospermic cat, despite the cheetah having a 10% longer midpiece. In both species, MMP was increased 5-fold in spermatozoa with retained cytoplasm compared with structurally normal cells. Inhibition of oxidative phosphorylation impaired sperm function in both species, but a 100-fold higher inhibitor concentration was required in the cat compared with the cheetah. Collectively, findings revealed that oxidative phosphorylation was required for sperm function in the domestic cat and cheetah. This pathway of energy production appeared markedly less active in the cheetah, indicating a species-specific vulnerability to mitochondrial dysfunction. The unexpected, cross-species linkage between retained cytoplasmic droplets and elevated MMP may reflect increased concentrations of metabolic enzymes or substrates in these structures.

Increasing primary productivity in tropical forests over recent decades has been attributed to CO sub(2) fertilization, and greater biomass in tropical forests could represent a substantial sink for carbon in the future. However, the carbon sequestration capacity of tropical forest soils is uncertain and feedbacks between increased plant productivity and soil carbon dynamics remain unexplored. Here, we show that experimentally increasing litterfall in a lowland tropical forest enhanced carbon release from the soil. Using a large-scale litter manipulation experiment combined with carbon isotope measurements, we found that the efflux of CO sub(2) derived from soil organic carbon was significantly increased by litter addition. Furthermore, this effect was sustained over several years. We predict that a future increase in litterfall of 30% with an increase in atmospheric CO sub(2) concentrations of 150ppm could release about 0.6tCha super(-1)yr super(-1 ) from the soil, partially offsetting predicted net gains in carbon storage. Thus, it is essential that plant-soil feedbacks are taken into account in predictions of the carbon sequestration potential of tropical forests.

Female blue monkeys contest fruits and have a linear dominance hierarchy, yet previous research has shown no evidence that high-ranking females benefit from greater feeding success or fertility. Here, we assess whether individuals differ in fecal glucocorticoid (fGC) excretion and examine proximate determinants of such differences to infer potential fitness correlates of rank, using data collected from two study groups in the Kakamega Forest, Kenya. We found that higher ranking females had preferential access to fruits in both groups, although the behavioral mechanisms leading to this effect varied between groups. Despite a consistent rank difference in feeding on fruits, an overall rank effect on fGCs emerged in only one group; females of this group spent comparatively more time feeding on fruits, fruits accounted for a greater proportion of the diet, and females engaged in more frequent food-related agonism. In addition, more females in this group were lactating during a period of low fruit availability, when rank effects on fGCs were particularly strong. Regardless of fruit availability, among lactating females of both groups higher rank was associated with lower fGC levels, indicating lower energetic stress in higher ranking females when energy demands were particularly high. Individual rates of agonism, a potential psychological stressor, were unrelated to fGCs at all times. After we accounted for rates of agonism and feeding on fruits, females of one group who groomed others more had lower fGCs, suggesting that variable social coping behavior can contribute to fGC variation in some groups. This study provides the first empirical evidence that high-ranking female blue monkeys may obtain fitness benefits from their social status, by gaining priority of access to fruits during critical times in the reproductive cycle.

Examining NEO albedos also sheds light on the differences between the NEO and Main Belt populations. We combine albedo results from the ExploreNEOs Warm Spitzer Exploration Science program with taxonomic classifications from the literature, publicly available data sets, and new observations from our concurrent spectral survey to derive the average albedos for C-, D-, Q-, S-, V-, and X-complex NEOs. Using a sample size of 118 NEOs, we calculate average albedos of 0.29 (super +0.05) (sub -0.04) , 0.26 (super +0.04) (sub -0.03) , and 0.42 (super +0.13) (sub -0.11) for the Q-, S-, and V-complexes, respectively. The averages for the C- and D-complexes are 0.13 (super +0.06) (sub -0.05) and 0.02 (super +0.02) (sub -0.01) , but these averages are based on a small number of objects (five and two, respectively) and will improve with additional observations. We use albedos to assign X-complex asteroids to one of the E-, M-, or P-types. Our results demonstrate that the average albedos for the C-, S-, V-, and X-complexes are higher for NEOs than the corresponding averages observed in the Main Belt. Copyright (Copyright) 2011.

These novelties are distinguished by shell and other morphologic characters and are well differentiated genetically from each other and from other congeners (mtCOI sequence divergence >1.9%). We also provide two new records for T. seemani (Frauenfeld, 1863), which is distributed near the southern limit of the Chihuahuan Desert (Durango State) and previously had been thought to be possibly extinct. Bayesian analysis of a mtCOI dataset resolved two clades composed of novelties described herein: one (containing four species) is distributed in several drainages in Chihuahua, the other (containing three species) is a local species flock in the Rio Conchos basin (also in Chihuahua) that lives in the warmest waters yet recorded for Tryonia (41-44 degree C). (The phylogenetic relationships of the other new species were not well supported.) Both of these clades contain sympatric species pairs; co-occurrence of Tryonia congeners previously had been reported only in Ash Meadows (southern Nevada). Some of the species described herein are from previously unsurveyed localities and may help delineate new areas of endemism within the Chihuahuan Desert. One of the new species (T. julimesensis) became extinct between 1991 and 2001 and another (T. oasiensis) disappeared from its single known locality shortly after it was first discovered in 2009 and also may be extinct. The other species treated herein are at risk of extirpation owing to the declining extent and condition of their unprotected habitats.

This Tier II final EIS analyzes five specific build alternatives and a No Action Alternative. The build alternatives each feature a Corona as the defining form of the visible building structure and the primary location for the galleries. Generally, four interior levels would be housed within the Corona and each alternative would feature two museum levels below grade. A primary entrance on the south side of the site would feature a hardscape plaza and service access and limited vehicular access would be provided from 14th Street. The building would incorporate passive heating and cooling, day lighting, comprehensive stormwater management, and energy conservation. Under Alternative 1, the Corona would sit atop a plinth that would accommodate a large ground floor program and frame the ground floor glass enclosure. Alternative 2 is based on a plaza concept and would divide the exhibit functions and administrative functions of NMAAHC into two distinct buildings. Alternative 3, the pavilion concept, is similar to Alternative 1, but without the plinth. Alternative 4, the refined pavilion concept, is similar to Alternative 3, but would feature a Corona with reduced above-grade dimensions and would include entries on both the north and south sides of the site. The Refined Pavilion 2 Alternative is the preferred alternative and evolved through the continued development of the museum design. Under this alternative, the Corona would be a singular, three-tiered building with vertical core elements providing the primary load-bearing support for the roof and gallery floors. The interior of the penthouse/5th floor would consist of office space, meeting rooms, and support space. Two full levels (the basement and the concourse) and a mezzanine level would be located below grade. The Refined Pavilion 2 Alternative would involve the construction of up to 372,000 gross square feet with a maximum effective building footprint of 59,100 square feet covering 25.3 percent of the site. The Corona would have an apparent height of 96.5 feet above grade and the height of the penthouse would be 109 feet above grade. POSITIVE IMPACTS: The museum would constitute the only institution providing a national meeting place for Americans to learn about the history and culture of African-Americans and their contributions to and relationship with every aspect of our national life. Increased visitation to the District of Columbia due to the attraction of the museum would boost the local economy. NEGATIVE IMPACTS: The museum would displace an open space on the Washington Monument grounds of the National Mall, altering the historic boundaries of the grounds and altering the spatial organization of the grounds by diminishing the prominence of the Washington Monument as a central organizing feature. Significant impacts would also occur for buildings and structures located within the Monument grounds as well as the Federal Triangle along Constitution Avenue. Vegetation would be removed and the viewshed and specific vistas would be altered. The museum would be situated in an area in violation of federal standards regarding ozone and particulate matter.

16469679 AB - Grapsoid crabs of the genera Planes and Plagusia are commonly referred to as "rafting crabs" due to their propensity to live on flotsam and pelagic marine animals. Planes minutus and Planes major (=Planes cyaneus) are epibionts of sea turtles. Occurrences of grapsoid crabs in the genera Planes and Plagusia were evaluated on a total of 27 olive ridley sea turtles, Lepidochelys olivacea, from the eastern tropic Pacific (1998-2001) and the Hawaiian Islands (2002) captured in July-December each year. This is the first report of Planes marinus and Plagusia squamosa on sea turtles, and of P. major, P. marinus, and P. squamosa in sympatry on a confined substrate. Stomach content analyses showed P. major and P. marinus consumed a variety of neuston and marine vegetation, with the former consuming considerably more animal material. Epibiotic P. squamosa consumed mostly plant material. The three Planes species had distinctive differences in gastric mill tooth morphology. The versatile mouthparts of P. marinus are described and resemble those of their congeners. Most female P. major and P. marinus collected were ovigerous and present in all survey months.

We replicated the eight factorial treatments four times using 32 plots of 40 x 40 m each. The addition of K was associated with significant decreases in stand-level fine-root biomass and, in a companion study of seedlings, decreases in allocation to roots and increases in height growth rates. The addition of K and N together was associated with significant increases in growth rates of saplings and poles (1-10 cm in diameter at breast height) and a further marginally significant decrease in stand-level fine-root biomass. The addition of P was associated with a marginally significant (P = 0.058) increase in fine-litter production that was consistent across all litter fractions. Our experiment provides evidence that N, P, and K all limit forest plants growing on a relatively fertile soil in the lowland tropics, with the strongest evidence for limitation by K among seedlings, saplings, and poles.

We tracked overwinter changes in the availability of arthropods and fruits, the primary winter foods of the Hermit Thrush (Catharus guttatus), a short-distance migrant. Fruit availability declined over the winter, and arthropod availability fluctuated with changing temperature. Concurrently, using fecal samples and stable isotopes, we tracked relative food consumption. In fecal samples fruit declined from early to mid season and delta super(13)C and delta super(15)N isotope signatures in blood became more enriched, consistent with a decline in fruit consumption and an increase in arthropod consumption. Larger-bodied birds, predominantly males, maintained territories in which the abundance of arthropods was higher, had a greater proportion of arthropods in their diet and less variation in delta super(13)C (indicator of a stable diet) and fat loads over the winter. In contrast, smaller-bodied birds, primarily females, gained fat midwinter in response to unpredictable and lower-quality resources. These results are consistent with both a size-mediated form of dominance and sexual habitat segregation, such that smaller bodied birds, mainly females, may be behaviorally excluded from optimal territories. Future research should focus on the long-term consequences of food limitation in the nonbreeding season and size and sex-mediated dominance behavior on both the condition of birds within a season and on subsequent breeding success and survival.

We present the first broad survey of geographic variation in the nuclear genome of breeding and wintering Wilson's warblers (Wilsonia pusilla), which have previously served as a research system for the study of whether genetic markers and isotopes can reveal patterns of migratory connectivity. Using 153 samples surveyed at up to 257 variable amplified fragment length polymorphism markers, we show that Wilson's warblers consist of highly distinct western and eastern breeding groups, with all winter samples grouping with the western breeding group. Within the west, there is weak geographic differentiation, at a level insufficient for use in the assignment of wintering samples to specific areas. The distinctiveness of western and eastern genetic groups, with no known intermediates, strongly suggests that these two groups are cryptic species. Analysis of mitochondrial cytochrome b sequence variation shows that the estimated coalescence time between western and eastern clades is approximately 2.3Ma, a surprisingly old time of divergence that is more typical of distinct species than of subspecies. Given their morphological similarity but strong genetic differences, western and eastern Wilson's warblers present a likely case of association between divergence in migratory behaviour and the process of speciation.

We used pre- and post-fire digital aerial photography to examine how the level of canopy damage varied within these plantations in relation to topography, weather, vegetation-cover, and management history, with an emphasis on the age of the plantation. We examined 198 plantations that varied widely in age (5-47years), size (1.25-47ha), and landscape context. The average level of canopy damage within the plantations was 77%. Based on Random Forest variable importance values, plantation age was the best predictor of canopy damage. Average annual precipitation, elevation and topographic position were ranked second, third, and fourth, respectively. A model selection procedure, using geo-statistical regression models and Akaike's information criterion, corroborated the importance of plantation age relative to the other predictors tested and also suggested that the influence of age varied over time. The top ranked regression model indicated that the level of canopy damage reached its maximum around age 15 and stayed relatively high until age 25 before declining.

Most previous studies have employed isotope or trace element proxies. This study uses morphological changes in erect and free-living cheilostome bryozoans as a proxy to investigate environmental change through the final stages of the Maastrichtian at the Nye Kloev section in Denmark. The metrics used are: (1) mean zooid size as a proxy for temperature; (2) intracolony variation in zooid size as a proxy for degree of seasonality; (3) density of defensive avicularia as a proxy for palaeoproductivity; and (4) colony size and asymmetry as proxies for unfavourable environmental conditions. Three semi-distinct phases in the benthic environment are evident: The lowest 3.5m of the roughly 4.5m section experienced apparently normal marine conditions. Next, low estimates of benthic seasonality, and highly symmetrical and large colonies with many avicularia indicate a time of increased environmental stability. Subsequent to this quiescence, the uppermost 20cm of the section witnessed environmental volatility and deterioration with mean zooid sizes in all species falling dramatically suggesting a rapid warming or dysoxic event, sharply increasing seasonality estimates implying unusual oceanographical states, and the growth of small, asymmetrical colonies with few avicularia all suggesting unfavourable conditions. These data therefore indicate that strong environmental perturbations occurred just prior to the K-T boundary in the Danish Basin. Such events may have contributed to biotic turnover at the K-T boundary because cause and effect in macroevolution can be delayed. However, potential mechanisms of turnover need to be robustly tested within a detailed palaeoenvironmental framework construct from a suite of independent proxies.

One such plant, Phragmites australis subsp. americanus is a perennial emergent grass found in tidal and inland marshes of the Atlantic coast of the United States. While rarely dominant, it grows in mixed communities and across much of this area its distribution has been reduced dramatically, likely due to eutrophication and the invasion of conspecific P. australis introduced from Europe. In this study, two noncoding cpDNA markers and six microsatellite loci were used to characterize genetic diversity among 58 remnant native P. australis stands from North Carolina to Maine. Five chloroplast DNA haplotypes were identified along with 42 multilocus genotypes. Bayesian exploration detected no population structure (e.g., optimal K = 1), indicating that these individuals form a single population. The analysis also detected no presence of hybrids of native and introduced P. australis in the samples, despite the close proximity of individuals to each other in many cases. These results suggest that the genetic composition of native P. australis across the region remains homogeneous and pure, providing managers with justification for its conservation and a potentially large source of germplasm for use in restoration activities.

Coherent periodic fluctuation in both origination and extinction of "short-lived" genera (those that survive 45 Myr) do not participate in the periodic fluctuation in diversity and differ from those of "short-lived" genera. The difference between the evolutionary dynamics of long- and short-lived genera indicates that the periodic pattern is not simply an artifact of variation in quality of the geologic record. Also, the interplay of these two previously undifferentiated systems, together with the secular increase in abundance of "long-lived" genera, is probably the source of observed but heretofore unexplained differences in evolutionary dynamics between the Paleozoic and post-Paleozoic as reported by others. Testing for cycles similar to the 62-Myr cycle in fossil biodiversity superimposed on the long-term trends of the Phanerozoic as described in Paper I, we find a significant (but weaker) signal in sedimentary rock packages, particularly carbonates, which suggests a connection. The presence of a periodic pattern in evolutionary dynamics of the more vulnerable "short-lived" component of the marine fauna demonstrates that a long-term periodic fluctuation in environmental conditions capable of affecting evolution in the marine realm characterizes our planet's history. Coincidence in timing is more consistent with a common cause than with sampling bias. A previously identified set of mass extinctions preferentially occur during the declining phase of the 62-Myr periodicity, supporting the idea that the periodicity relates to variation in biotically important stresses. Further work should focus on finding links to physical phenomena that might reveal the causal system or systems.

A test using veneroid bivalves from the Plio-Pleistocene of Florida AN - 875015528; 2011-055250 AB - Although morphological variation is known to influence the evolutionary fates of species, the relationship between morphological variation and survivorship in the face of extinction-inducing perturbations is poorly understood. Here, we investigate this relationship for veneroid bivalves in association with the Plio-Pleistocene extinction in Florida. Fourteen pairs of related species were selected for analysis, with each pair including one species that survived the Plio-Pleistocene extinction and another that became extinct during the interval. Morphological landmark data were acquired for more than 1500 museum specimens, representing 19 localities that encompass four well-known Plio-Pleistocene units in the study region. Procrustes superimposition was applied to each sample, and overall multivariate variation was calculated as the mean squared partial Procrustes distance between specimens and their mean form. Morphological variation was calculated at three geographic scales for each species, and differences in variation between survivors and victims were examined within each species pair. Results indicate that species surviving the Plio-Pleistocene extinction were significantly more variable morphologically than victims. Greater morphological variation may promote survivorship by directly enhancing species adaptations to changing conditions or by permitting the occupation of a larger geographic range. Alternatively, high morphological variation and survivorship may both be mediated by a third variable, such as large geographic range.

Upper Cretaceous-Lower Eocene strata rest unconformably upon Jurassic igneous rocks of the Santa Marta Massif, with no major thrust faults separating the Santa Marta Massif from the Rancheria Basin. The upper Campanian-Lower Eocene succession includes, from base to top: foraminifera-rich calcareous mudstone, mixed carbonate-siliciclastic strata and mudstone, coal and immature fluvial sandstone beds. Diachronous collision and eastward tilting of the plate margin (Santa Marta Massif and Central Cordillera) favoured the generation of accommodation space in a continuous intraplate basin (Rancheria, Cesar and western Maracaibo) during the Maastrichtian to Late Palaeocene. Terrigenous detritus from the distal colliding margin filled the western segments of the continuous intraplate basin (Rancheria and Cesar Basins); in the Late Paleocene, continental depositional systems migrated eastwards as far as the western Maracaibo Basin. In Early Eocene time, reactivation of former extensional structures fragmented the intraplate basin into the Rancheria-Cesar Basins to the west, and the western Maracaibo Basin and Palmar High to the East. This scenario of continent-oceanic arc collision, crustal-scale tilting, intraplate basin generation and fault reactivation may apply for Upper Cretaceous-Palaeogene syntectonic basins in western Colombia and Ecuador, and should be considered in other settings where arc-continent collision is followed by subduction.

Depending on its elevation within the marsh, S. alterniflora may be submerged for several hours per day. Previous ecosystem-level studies have demonstrated that S. alterniflora marshes are a net sink for nitrogen (N), and that removal of N from flooding tidal water can provide enough N to support the aboveground biomass. However, studies have not specifically investigated whether S. alterniflora plants assimilate nutrients through their aboveground tissue. We determined in situ foliar and stem N uptake kinetics for super(15)NH sub(4), super(15)NO sub(3), and super(15)N-glycine by artificially flooding plants in a mid-Atlantic salt marsh. To determine the ecological importance of shoot uptake, a model was created to estimate the time of inundation of S. alterniflora in 20 cm height intervals during the growing season. Estimates of inundation time, shoot mass, N uptake rates, and N availability from long-term data sets were used to model seasonal shoot N uptake. Rates of aboveground N uptake rates (leaves + stems) were ranked as follows: NH sub(4) super(+) glycine NO sub(3) super(-). Our model suggests that shoot N uptake may satisfy up to 15% of the growing season N demand in mid-Atlantic salt marshes, with variation depending on plant elevation and water column N availability. However, in eutrophic estuaries, our model indicates the potential of the plant canopy as a nutrient filter, with shoot uptake contributing 66 to 100% of plant N demand.

The ecological impact of sea-level change on benthic feeding areas in the North Pacific Ocean AN - 925708168; 2012-027645 AB - Gray whales (Eschrichtius robustus) undertake long migrations, from Baja California to Alaska, to feed on seasonally productive benthos of the Bering and Chukchi seas. The invertebrates that form their primary prey are restricted to shallow water environments, but global sea-level changes during the Pleistocene eliminated or reduced this critical habitat multiple times. Because the fossil record of gray whales is coincident with the onset of Northern Hemisphere glaciation, gray whales survived these massive changes to their feeding habitat, but it is unclear how. We reconstructed gray whale carrying capacity fluctuations during the past 120,000 years by quantifying gray whale feeding habitat availability using bathymetric data for the North Pacific Ocean, constrained by their maximum diving depth. We calculated carrying capacity based on modern estimates of metabolic demand, prey availability, and feeding duration; we also constrained our estimates to reflect current population size and account for glaciated and non-glaciated areas in the North Pacific. Our results show that key feeding areas eliminated by sea-level lowstands were not replaced by commensurate areas. Our reconstructions show that such reductions affected carrying capacity, and harmonic means of these fluctuations do not differ dramatically from genetic estimates of carrying capacity. Assuming current carrying capacity estimates, Pleistocene glacial maxima may have created multiple, weak genetic bottlenecks, although the current temporal resolution of genetic datasets does not test for such signals. Our results do not, however, falsify molecular estimates of pre-whaling population size because those abundances would have been sufficient to survive the loss of major benthic feeding areas (i.e., the majority of the Bering Shelf) during glacial maxima. We propose that gray whales survived the disappearance of their primary feeding ground by employing generalist filter-feeding modes, similar to the resident gray whales found between northern Washington State and Vancouver Island.

As embryos develop, their needs and abilities change, altering the costs and benefits of encapsulation, and the risks and opportunities of the outside world. When the cost/benefit ratio is better outside the egg, animals should hatch. Adaptive timing of hatching evolves in this context. However, many environmental variables affect the optimal timing of hatching so there is often no consistent best time. Across a broad range of animals, from flatworms and snails to frogs and birds, embryos hatch at different times or at different developmental stages in response to changing risks or opportunities. Embryos respond to many types of cues, assessed via different sensory modalities. Some responses appear simple. Others are surprisingly complex and sophisticated. Parents also manipulate the timing of hatching. The number and breadth of examples of cued hatching suggest that, in the absence of specific information, we should not assume that hatching timing is fixed. Our challenge now is to integrate information on the timing of hatching across taxa to better understand the diversity of patterns and how they are structured in relation to different types of environmental and developmental variation. As starting points for comparative studies, I: (1) suggest a framework based on heterokairy-individual, plastic variation in the rate, timing, or sequence of developmental events and processes-to describe patterns and mechanisms of variation in the timing of hatching; (2) briefly review the distribution of environmentally cued hatching across the three major clades of Bilateria, highlighting the diverse environmental factors and mechanisms involved; and (3) discuss factors that shape the diversity of plastic and fixed timing of hatching, drawing on evolutionary theory on phenotypic plasticity which directs our attention to fitness trade-offs, environmental heterogeneity, and predictive cues. Combining mechanistic and evolutionary perspectives is necessary because development changes organismal interactions with the environment. Integrative and comparative studies of the timing of hatching will improve our understanding of embryos as both evolving and developing organisms.

This study uses carbon and oxygen isotope ratios of pedogenic carbonates to examine environmental variability across approximately 5000 km (super 2) within the Omo-Turkana Basin. An expanded isotopic dataset, including the first isotopic data on pedogenic carbonates from the Shungura Formation and new data from the Nachukui and Koobi Fora formations, is compared to published isotopic records from both the Omo-Turkana Basin and the lower Awash Basin, Ethiopia. Regionally, the carbon isotope record indicates a steady increase of C (sub 4) vegetation in floodplain environments for the past 4 million years. The oxygen isotopic record indicates that the isotopic composition of rainfall was depleted in (super 18) O relative to today's waters and that both basins likely received more rainfall in the Pliocene than today. A shift to higher delta (super 18) O values in paleosol carbonate after 2 Ma in the Omo-Turkana Basin but not in the lower Awash Basin suggests that the ecology and hydrology in these two rift basins were influenced by different climatic regimes. In addition to regional trends, pedogenic carbonates sampled from different parts of the basin show that the distribution of C (sub 4) vegetation and soil water delta (super 18) O values varied with proximity to the axial river system, and specifically that C (sub 3) vegetation was more dominant in soils of the Shungura Formation compared with coeval sediments downstream in the Nachukui and Koobi Fora formations. This large isotopic dataset from pedogenic carbonates provides the opportunity to examine how terrestrial systems responded to global climate change during the last 4 million years, from both local and regional perspectives. The isotopic data indicate that local basin and climate dynamics strongly influenced the impact of large-scale environmental change in East African rift basins.

Moreover, our ability to quantify migratory connectivity has inevitable consequences for both conservation and management of species that utilize distinct geographic locations. Technology is rapidly advancing our ability to track birds throughout the annual cycle and to collect data on the degree of connectivity among breeding and nonbreeding populations. We combined two direct methods, mark-recapture (n = 17) and geolocation (n = 6), to estimate the migratory connectivity of breeding and nonbreeding populations of Gray Catbirds (Dumetella carolinensis). Data from geolocators show that birds breeding in the Mid-Atlantic overwinter in both Cuba and southern Florida. Mark-recapture data supported our geolocator results but also provided a broader spatial perspective by documenting that Mid-Atlantic and Midwestern populations occupy distinct geographic localities during the nonbreeding period. This research underscores the importance of geolocators, as well as other tools, to advance our understanding of migratory connectivity.

We combined geographic methods that account for buffer prevalence along flow paths connecting croplands to streams with improved statistical models to test for buffer effects on stream nitrate concentrations from 321 tributary watersheds to the Chesapeake Bay, USA. We developed statistical models that predict stream nitrate concentration from watershed land cover and physiographic province. We used information theoretic methods (AIC sub(c)) to compare models with and without buffer terms, and we demonstrate that models accounting for riparian buffers better explain stream nitrate concentrations than models using only land cover proportions. We analyzed the buffer model parameters to quantify differences within and among physiographic provinces in the potentials for nitrate loss from croplands and nitrate removal in buffers. On average, buffers in Coastal Plain study watersheds had a higher relative nitrate removal potential (95% of the inputs from cropland) than Piedmont buffers (35% of inputs). Buffers in Appalachian Mountain study watersheds were intermediate (retaining 39% of cropland inputs), but that percentage was uncertain. The absolute potential to reduce nitrate concentration was highest in the Piedmont study watersheds because of higher nitrate inputs from cropland. Model predictions for the study watersheds provided estimates of nitrate removals achieved with the existing cropland and buffer distributions. Compared to expected nitrate concentrations if buffers were removed, current buffers reduced average nitrate concentrations by 0.73 mg N/L (50% of their inputs from cropland) in the Coastal Plain study watersheds, 0.40 mg N/L (11%) in the Piedmont, and 0.08 mg N/L (5%) in the Appalachian Mountains. Restoration to close all buffer gaps downhill from croplands would further reduce nitrate concentrations by 0.66 mg N/L, 0.83 mg N/L, and 0.51 mg N/L, respectively, in the Coastal Plain, Piedmont, and Appalachian Mountain study watersheds. Aggregate nitrate removal by riparian buffers was less than suggested by many studies of field-to-stream transects, but buffer nitrate removal is significant, and restoration could achieve substantial additional removal.

In testing prior understandings of the paleoenvironmental context, we define nine new geochemical zones. A Chemical Index of Alteration suggests increased catchment weathering during deposition of Members 1, 2, 7, 11, and 13. Biophile elements (Br, S) peak in M8-9 and lower M13 possibly reflecting increased input from soil erosion. REE data show that the Magadi Trachytes supplied most siliciclastic grains. Sixteen diatom stages indicate conductivities of 200-16,000mu Scm (super -1) and pH of 7.5-9.5 for five deep-water lakes, ten shallow lakes and sixteen wetlands. These results are compared with diatom data from other sections in the basin and show aquatic spatial variability over km-scale distances. Similar floras are traceable over several kilometers for M2, M3 and M9, indicating broadly homogeneous lacustrine conditions during these times, but diatoms in other members imply variable conditions, some related to local tectonic controls. This lateral and temporal variability emphasizes the importance of carrying out stratigraphic sampling at multiple sites within a basin in efforts to define the environmental context relevant to human evolution.

These represent the first rate equations calculated for cation exchange in layered manganates. Our previous work has shown that the substitution of K, Cs, and Ba for interlayer Na in synthetic triclinic birnessite induces measurable changes in unit-cell parameters. New kinetic modeling of this crystallographic data supports our previously postulated two-stage reaction pathway for cation exchange, and we can correlate the kinetic steps with changes in crystal structure. In addition, the initial rates of cation exchange, R (A (super 3) min (super -1) ), were determined from changes in unit-cell volume to follow these rate laws: R=1.75[K+(aq)] (super 0.56) , R=41.1[Cs+(aq)] (super 1.10) , R=1.15[Ba2+(aq)] (super 0.50) . Thus, the exchange rates for Na in triclinic birnessite decreased in the order: Cs>>K>Ba. These results are likely a function of hydration energy differences of the cations and the preference of the solution phase for the more readily hydrated cation.

As determined by their stratigraphic position and geochronological data, these deposits formed during marine isotope substage (MIS) 5c ca. 100 ka ago. Within a leeward set of eolian beds, evidence of a living landscape was preserved that includes delicate footprints of a shorebird (Scolopacidae, Catoptrophorus) preserved in frothy dune foreset beds. In the same stratigraphic unit, outlines of a standing forest of palm trees (Sabal bermudana), some evidently with fronds in place, were molded in the fine carbonate dune sand. All available evidence points to an MIS 5c sea level positioned several meters below the present datum, which would require great intensity of storms to transport such voluminous deposits well above present sea level. Waves and storm currents transported loose sediments from the shallow shelf onto the shore, where hurricane winds piled up sand sufficiently deep to bury established forests of 8- to 10-m-tall trees. Evidence of such powerful storms preserved in the rock record is a measure of the intensity of past hurricanes, and a possible bellwether of future storm events. Entombment of the trees involved rapid burial and cementation creating external molds in limestone, a process that is important in the development of vertical hydrological conduits commonly observed in eolianites.

The major component of these rocks are serpentine group minerals [Mg (sub 3) Si (sub 2) O (sub 5) (OH) (sub 4) ], showing highly variable textural and geochemical features. Micro-Raman spectroscopy reveals that the serpentine minerals are well-crystallized lizardite and chrysotile. In situ SIMS spot analyses and element mapping via ToF-SIMS show that B is evenly distributed across serpentine grains, suggesting that serpentine, both lizardite and chrysotile in different textural regions, can host significant amounts of B (up to approximately 200 mu g/g) into its crystal structure. As such structurally bound B can only be released during recrystallization or serpentine breakdown, our results have implications for modeling of the efficiency of cross-arc fluid mobile element recycling in subduction zones and stress the importance of the hydrated forearc mantle as a reservoir for fluid mobile elements.

However, for several regions, historical data and observations obtained by remote sensing raise some controversy over the portrait accepted in international circles. This case study, located in the central plateau of Angola, highlights the importance of medium to high resolution multi-temporal observations of land cover by remote sensing as a means of obtaining objective information and illustrates the complexity of deforestation processes. Land cover change in the Huambo province (Angola) is analyzed using maps produced for three dates (in the period between 1990 and 2009) by classification of Landsat TM and ETM+ images. The results are a first stepping stone for the development of a forest monitoring baseline for REDD projects under the scope of post-Kioto agreements, and they indicate an overall recovery in the forest extent of Huambo (negative deforestation rate of -0.16%, contrasting with the +0.20% reported for the entire country). However, this apparent recovery hides an inversion in the dynamics of the more densely wooded vegetation types, the miombo woodlands, which show a very slight expansion in the first decade analyzed and a marked reduction in the second, while agriculture shows a consistent and constant expansion. The deforestation rate of 1.49% in miombo woodlands in the last decade is found to be seven times higher when compared with official figures reported for the entire country. These results are discussed in the context of the socio-economic factors that may have driven the observed dynamics.

We studied the life-history strategies, demography and population growth of white-tailed ptarmigan Lagopus leucura, an alpine specialist, at the latitudinal extremes of the range in the Yukon (YK, studied from 2004 to 2008) and Colorado (CO, 1987-1996). The two populations were separated by 2,400km of latitude, and the Yukon site was approximately 2,000m lower in elevation than the Colorado site. Yukon females bred on average 9days earlier than those in Colorado, but the latter study was conducted 15years earlier and breeding dates may have advanced over this period. The length of the breeding season was similar between the two populations, and females had comparable probabilities of re-nesting after failure. The two populations differed in how they allocated effort to the first clutch as Yukon females laid larger clutches (7.1 vs. 5.9 eggs) but smaller eggs (18.8 vs. 20.5g) than those in Colorado. Demographic rates also differed; nest survival was higher in the Yukon (0.40) than in Colorado (0.24), and the resultant annual fecundity was nearly twice as high in the Yukon (3.92 vs. 1.77 chicks/female). In contrast, annual adult survival was higher in Colorado although the confidence intervals overlapped (females: YK=0.35, CO=0.44; males: YK=0.48, CO=0.59). Estimates of annual population growth ( lambda ) indicated both populations were declining, especially in Colorado ( lambda sub(YK)=0.83, lambda sub(CO)=0.66), and thus, dispersal movements are likely key to long-term persistence in both cases. Our findings suggest that breeding-season temperature and seasonality affect measures related to timing of reproduction, but not the costs and benefits of clutch and egg size.

To understand the role of wetlands in the global carbon cycle, it is critical to understand how differences in both electron donor (i.e., organic carbon) and terminal electron acceptor (TEA) availability influence anaerobic mineralization of soil organic matter. In this study we manipulated electron donors and acceptors to examine how these factors influence total rates of carbon mineralization and the pathways of microbial respiration (e.g., sulfate reduction versus methanogenesis). Using a field-based reciprocal transplant of soils from brackish and freshwater tidal marshes, in conjunction with laboratory amendments of TEAs, we examined how rates of organic carbon mineralization changed when soils with different carbon contents were exposed to different TEAs. Total mineralization (the sum of CO sub(2 + CH) sub(4) produced) on a per gram soil basis was greater in the brackish marsh soils, which had higher soil organic matter content; however, on a per gram carbon basis, mineralization was greater in the freshwater soils, suggesting that the quality of carbon inputs from the freshwater plants was higher. Overall anaerobic metabolism was higher for both soil types incubated at the brackish site where SO sub(4[super]2- was the dominant TEA. When soils were amended with TEAs in the laboratory, more thermodynamically favorable respiration pathways typically resulted in greater organic matter mineralization (Fe(III) respiration > SO) sub(4)[super]2- reduction > methanogenesis). These results suggest that both electron donors and acceptors play important roles in regulating anaerobic microbial mineralization of soil organic matter.

We present substantially more Southern Hemisphere and deep-sea taxa than were sampled in previous molecular studies of this group. Morphologically distinct groups, such as the Brisingida and the Zoroasteridae, are upheld as monophyletic. Brisingida is supported as the derived sister group to the Asteriidae (restricted), rather than as a basal taxon. The Asteriidae is paraphyletic, and is broken up into the Stichasteridae and four primary asteriid clades: (1) a highly diverse boreal clade, containing members from the Arctic and sub-Arctic in the Northern Hemisphere; (2) the genus Sclerasterias; (3) and (4) two sister clades that contain asteriids from the Antarctic and pantropical regions. The Stichasteridae, which was regarded as a synonym of the Asteriidae, is resurrected by our results, and represents the most diverse Southern Hemisphere forcipulatacean clade (although two deep-sea stichasterid genera occur in the Northern Hemisphere). The Labidiasteridae is artificial, and should be synonymized into the Heliasteridae. The Pedicellasteridae is paraphyletic, with three separate clades containing pedicellasterid taxa emerging among the basal Forcipulatacea. Fossils and timing estimates from species-level phylogeographic studies are consistent with prior phylogenetic hypotheses for the Forcipulatacea, suggesting diversification of basal taxa in the early Mesozoic, with some evidence for more widely distributed ranges from Cretacous taxa. Our analysis suggests a hypothesis of an older fauna present in the Antarctic during the Eocene, which was succeeded by a modern Antarctic fauna that is represented by the recently derived Antarctic Asteriidae and other forcipulatacean lineages. copyright 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 162, 646-660.

On the Channel Islands, the Late Holocene was a time of substantial population growth, territoriality, and the emergence of social hierarchies. The role of marine and terrestrial climate change, population growth, human environmental impacts, and other variables in driving Late Holocene cultural and ecological developments is a subject of considerable debate. Analysis of faunal remains (especially finfish and shellfish), complemented by human skeletal and stable isotope analyses, from a massive shell midden and village complex (CA-SRI-2) on Santa Rosa Island provides insight into Late Holocene human responses to coastal resource stress and environmental change. Despite significant population growth, the emergence of social stratification, and increased pressure on local resources and ecosystems, these data demonstrate that there is significant continuity in the coastal resources Channel Island peoples exploited through time. These results document the long-term resilience and adaptability of coastal hunter-gatherers, the marine resources they harvested, and Channel Island ecosystems.

The demise of this taxon remains obscure because of uncertainties regarding the geological age of its youngest populations. In 1996, some of us co-published electron spin resonance (ESR) and uranium series (U-series) results indicating an age as young as 35-50 ka for the late H. erectus sites of Ngandong and Sambungmacan and the faunal site of Jigar (Indonesia). If correct, these ages favor an African origin for recent humans who would overlap with H. erectus in time and space. Here, we report (super 40) Ar/ (super 39) Ar incremental heating analyses and new ESR/U-series age estimates from the "20 m terrace" at Ngandong and Jigar. Both data sets are internally consistent and provide no evidence for reworking, yet they are inconsistent with one another. The (super 40) Ar/ (super 39) Ar analyses give an average age of 546 + or - 12 ka (sd + or - 5 se) for both sites, the first reliable radiometric indications of a middle Pleistocene component for the terrace. Given the technical accuracy and consistency of the analyses, the argon ages represent either the actual age or the maximum age for the terrace and are significantly older than previous estimates. Most of the ESR/U-series results are older as well, but the oldest that meets all modeling criteria is 143 ka + 20/-17. Most samples indicated leaching of uranium and likely represent either the actual or the minimum age of the terrace. Given known sources of error, the U-series results could be consistent with a middle Pleistocene age. However, the ESR and (super 40) Ar/ (super 39) Ar ages preclude one another. Regardless, the age of the sites and hominins is at least bracketed between these estimates and is older than currently accepted.

However, hatchery-reared animals may be maladapted to the natural environment as a result of morphological, physiological, or behavioral deficiencies acquired during the hatchery phase. To assess the competency of hatchery-reared blue crabs Callinectes sapidus Rathbun, a species under consideration for restocking in Chesapeake Bay, we compared survival and growth of hatchery-reared and wild juveniles using complementary field tethering experiments and small-scale field releases in shallow blue crab nursery habitats of the upper Chesapeake Bay. We observed no difference in the survival rates of hatchery-reared and wild crabs in either tethering experiments or paired field releases. Hatchery-reared and wild juveniles also exhibited similar growth rates and levels of growth variability. The results indicate that hatchery-reared juveniles are competent and likely not disadvantaged relative to wild conspecifics, and that poor performance of hatchery-reared individuals following release is not a significant barrier to restocking for this species in Chesapeake Bay. Further, our study highlights the potential utility of release experiments with hatchery-reared animals to provide key biological data for stock assessments and fishery management.

AN - 954642349; 16419023 AB - In tropical forests, regional differences in annual rainfall correlate with differences in plant species composition. Although water availability is clearly one factor determining species distribution, other environmental variables that covary with rainfall may contribute to distributions. One such variable is light availability in the understory, which decreases towards wetter forests due to differences in canopy density and phenology. We established common garden experiments in three sites along a rainfall gradient across the Isthmus of Panama in order to measure the differences in understory light availability, and to evaluate their influence on the performance of 24 shade-tolerant species with contrasting distributions. Within sites, the effect of understory light availability on species performance depended strongly on water availability. When water was not limiting, either naturally in the wetter site or through water supplementation in drier sites, seedling performance improved at higher light. In contrast, when water was limiting at the drier sites, seedling performance was reduced at higher light, presumably due to an increase in water stress that affected mostly wet-distribution species. Although wetter forest understories were on average darker, wet-distribution species were not more shade-tolerant than dry-distribution species. Instead, wet-distribution species had higher absolute growth rates and, when water was not limiting, were better able to take advantage of small increases in light than dry-distribution species. Our results suggest that in wet forests the ability to grow fast during temporary increases in light may be a key trait for successful recruitment. The slower growth rates of the dry-distribution species, possibly due to trade-offs associated with greater drought tolerance, may exclude these species from wetter forests.

This is due, on the one hand, to farmers' nonexistent or reduced access to agro-chemicals, irrigation facilities, and seeds, and on the other hand, to the fact that they did not fulfil the farmers' socioeconomic and cultural priorities and needs. An understanding of farmers' criteria for variety selection is key to promoting effective plant breeding and achieving broader aims of food security and food sovereignty. Based on extensive ethnographic field research, this paper discusses rice biodiversity management strategies and the experimental skills and knowledge of Southern Guinea-Bissau farmers against the backdrop of failures by development interventions to introduce modern rice varieties. I conclude that the present cereal crises and environmental concerns should reshape researchers' exclusive priorities on genetic engineering in order to identify economically valued landraces, and promote their dissemination through participatory seed self-sufficiency approaches.

The distinctive coprolites are circular to oval in shape, ranging on average from 944X1190 mu m to 1065X1120 mu m, and contain histologically identifiable tracheids, parenchyma, gum sac cells, spores and fungal remains. Several lines of evidence indicate that this association was detritivorous, represented a pith boring, and was made by a diplopod or more likely an insect. This discovery extends the temporal duration of the food web of Psaronius plant-arthropod associations from the late Middle Pennsylvanian to now the Late Permian, and extends the biogeographic range from the equatorial wetlands of the Illinois, Northern Appalachian, and German Erzgebirge Basins of Euramerica to now the South China Block of Cathaysia.

Remediation methods of the last half century have been largely unsuccessful. In many US watersheds, surface waters are eutrophic, and coastal water bodies, such as the Chesapeake Bay and the Gulf of Mexico, have become increasingly hypoxic. The algal turf scrubber (ATS) is an engineered system for flowing pulsed wastewaters over sloping surfaces with attached, naturally seeded filamentous algae. This treatment has been demonstrated for tertiary sewage, farm wastes, streams, and large aquaculture systems; rates as large as 40 million to 80 million liters per day (lpd) are routine. Whole-river-cleaning systems of 12 billion lpd are in development. The algal biomass, produced at rates 5 to 10 times those of other types of land-based agriculture, can be fermented, and significant research and development efforts to produce ethanol, butanol, and methane are under way. Unlike with algal photobioreactor systems, the cost of producing biofuels from the cleaning of wastewaters by ATS can be quite low.

Multivariate statistics were run on autecological information for 29 extant ostracode species collected in 63 aquatic ecosystems on the Yucatan Peninsula along a steep, increasing NW-S precipitation gradient and across a large altitudinal range. Conductivity and water depth are the most important factors that shape ostracode communities. Transfer functions were developed and applied to fossil ostracode assemblages in a approximately 76-m sediment core (PI-6, approximately 85 ka) taken in 71 m of water from Lago Peten Itza, to infer past shifts in conductivity and water level. Results suggest climate was cold and wet during the Last Glacial Maximum (LGM). Alternating dry and wet conditions characterized the deglacial. Early Holocene climate was warmer and wetter. The LGM was characterized by low ostracode species richness (4 spp.) and abundance (<940 valves g (super -1) ), dominance of benthic over nektobenthic taxa, abundant Physocypria globula, conductivity as low as 190 mu S cm (super -1) , and clay-rich sediments with relatively high total organic carbon and low C/N ratios (<14), suggesting relatively deeper water at the core site associated with abundant precipitation. Greatest water depth at the core site during the LGM occurred late in the period and was approximately 50 m. The deglacial was characterized by drier conditions, higher ostracode species richness (6 spp.) and abundances up to 18,115 valves g (super -1) , dominance of nektobenthic species, and presence of shallow-water and littoral-zone indicators such as Heterocypris punctata and Strandesia intrepida, conductivity up to 550 mu S cm (super -1) , C/N ratios as high as 37, and gypsum deposition. Lowest inferred lake depth at the core site during the deglacial was approximately 20 m. The early Holocene was characterized by high numbers of ostracode remains, up to 25,500 valves g (super -1) , and the presence of L. opesta and P. globula. Cytheridella ilosvayi was absent from late Pleistocene sediments, suggesting it colonized northern Central America during the Holocene. Copyright 2011 Springer Science+Business Media B.V.

Exploration in this region is problematic owing to structural complexities, rapid lateral facies changes, and the difficulties of acquiring good seismic imaging. These elements increase the uncertainties about the prognosis and subsequent drilling of exploratory wells. Under these conditions, biostratigraphy can play a significant role in the exploratory process. In the Llanos Foothills, palynology is the most useful biostratigraphic tool because pollen is the most abundant fossil group. In this study we analyze pollen information from 70 sections (624,744 palynomorph grains from 6707 samples) to construct a biostratigraphic zonation for the Llanos Foothills and Llanos basins. Using both graphic correlation and constrained optimization in our analysis, we propose 18 palynological zones for the Cenozoic of the Llanos and Llanos Foothills. These zones are tied to the geological timescale using 18 calibration points that include carbon isotopes, foraminifera, and magnetostratigraphy.

Pink diamonds from Argyle in Australia and from Santa Elena in Venezuela show distinct visual and spectroscopic features compared to diamonds from other localities. Their pink color is prominent and has a banded pattern, sometimes wavy, interlaced with smaller bands of colorless areas. The birefringence indicates that the plastic deformation is located mostly inside the colorless areas for Argyle and Santa Elena diamonds, and inside the pink areas for other diamonds. Cathodoluminescence (CL) images show that plastic deformation features cut across the growth patterns of the diamonds. They quench partially the CL in colorless areas, while the pink areas retain growth sectors, as delineated in CL images by H3 and N3 centers. For other pink diamonds, the colored lamellae contain H3 and 405.5 nm centers. It is possible that for Argyle and Santa Elena diamonds, a pre-existing pink color was partially quenched during a later episode of plastic deformation. Conversely, diamonds from other localities apparently acquired their pink color from a later stage of plastic deformation. The geological settings of diamonds from Argyle in Australia and Santa Elena in Venezuela are similar, forming underneath Proterozoic cratons (and not the typical Archean cratons), that experienced high thermal events in their early histories.

2013-084187 AB - The identification and characterization of numerous collisional families-clusters of bodies with a common collisional origin-in the asteroid belt has added greatly to the understanding of asteroid belt formation and evolution. More recent study has also led to an appreciation of physical processes that had previously been neglected (e.g., the Yarkovsky effect). Collisions have certainly played an important role in the evolution of the Kuiper Belt as well, though only one collisional family has been identified in that region to date, around the dwarf planet Haumea. In this paper, we combine insights into collisional families from numerical simulations with the current observational constraints on the dynamical structure of the Kuiper Belt to investigate the ideal sizes and locations for identifying collisional families. We find that larger progenitors (r approximately 500 km) result in more easily identifiable families, given the difficulty in identifying fragments of smaller progenitors in magnitude-limited surveys, despite their larger spread and less frequent occurrence. However, even these families do not stand out well from the background. Identifying families as statistical overdensities is much easier than characterizing families by distinguishing individual members from interlopers. Such identification seems promising, provided the background population is well known. In either case, families will also be much easier to study where the background population is small, i.e., at high inclinations. Overall, our results indicate that entirely different techniques for identifying families will be needed for the Kuiper Belt, and we provide some suggestions. Copyright (Copyright) 2011.

This early stage occurs much before the dispersal of most of the gas from the protoplanetary disk. Due to their different aerodynamic properties, planetesimals of different sizes and shapes experience different drag forces from the gas during this time. Such differential forces produce a wind-shearing (WISH) effect between close by, different-sized planetesimals. For any two planetesimals, a WISH radius can be considered at which the differential acceleration due to the wind becomes greater than the mutual gravitational pull between the planetesimals. We find that the WISH radius could be much smaller than the gravitational shearing radius by the star (the Hill radius). In other words, during the gas-phase of the disk, WISH could play a more important role than tidal perturbations by the star. Here, we study the WISH radii for planetesimal pairs of different sizes and compare the effects of wind and gravitational shearing (drag force versus gravitational tidal force). We then discuss the role of WISH for the stability and survival of binary planetesimals. Binaries are sheared apart by the wind if they are wider than their WISH radius. WISH-stable binaries can also inspiral, and possibly coalesce, due to gas drag. Here, we calculate the WISH radius and the gas-drag-induced merger timescale, providing stability and survival criteria for gas-embedded binary planetesimals. Our results suggest that even WISH-stable binaries may merge in times shorter than the lifetime of the gaseous disk. This may constrain currently observed binary planetesimals to have formed far from the star or at a late stage after the dispersal of most of the disk gas. We note that the WISH radius may also be important for other processes such as planetesimal erosion and planetesimal encounters and collisions in a gaseous environment. Copyright (Copyright) 2011.

The great divide in maximal ability to exchange CO (sub 2) for water between leaves of nonangiosperms and angiosperms forms the mechanistic foundation for speculation about how angiosperms drove sweeping ecological and biogeochemical change during the Cretaceous. However, there is no empirical evidence that angiosperms evolved highly photosynthetically active leaves during the Cretaceous. Using vein density (DV) measurements of fossil angiosperm leaves, we show that the leaf hydraulic capacities of angiosperms escalated several-fold during the Cretaceous. During the first 30 million years of angiosperm leaf evolution, angiosperm leaves exhibited uniformly low vein DV that overlapped the DV range of dominant Early Cretaceous ferns and gymnosperms. Fossil angiosperm vein densities reveal a subsequent biphasic increase in DV. During the first mid-Cretaceous surge, angiosperm DV first surpassed the upper bound of DV limits for nonangiosperms. However, the upper limits of DV typical of modern megathermal rainforest trees first appear during a second wave of increased DV during the Cretaceous-Tertiary transition. Thus, our findings provide fossil evidence for the hypothesis that significant ecosystem change brought about by angiosperms lagged behind the Early Cretaceous taxonomic diversification of angiosperms.

Interest in native species is growing across the tropics as reforestation of degraded lands becomes more widespread. In this study four tree species native to Panama aCedrela odorata, Pachira quinata, Samanea saman, and Tabebuia rosea a were grown on rural farms at two dry tropical sites in Panama for up to five years. Survivorship and growth data at these aon-farma trials are compared to data recorded from nearby experimental or aspecies selectiona trial sites and evaluated in terms of soil fertility and management. Participant farmers were also asked about their interest in planting trees in general as well as their interest in 61 species grown in the species selection trial. Although, on-farm survivorship was variable and generally lower than that found on the species selection trial, one species (S. saman) experienced high and consistent survivorship. High survivorship combined with growth data from farms at both sites for this species suggests it would be a good candidate for extension projects working with rural farmers. Survivorship of other species appears more sensitive to farmer management and/or local site conditions. Generally lower growth on the Los Santos farms as compared to the species-selection trial is attributed to the lower soil fertility (plant available P) at the on-farm sites compared to the species selection trial. In contrast, only one species aP. quinata a had a growth variable found to be significantly lower between the on-farm and species selection trial sites in Rio Hato. C. odorata, P. quinata T. rosea can all be used in on-farm conditions with consideration to specific site and management conditions. By 2009, approximately 80% of the farmers planting trees still wished to participate in tree planting activities. All of the farmers no longer wishing to continue with the project expressed slow growth rates of trees as a principal reason. All but one of these farmers had growth rates for his/her trees markedly below those of the species selection trial nearby. Some farmers wishing to continue had very high mortality rates (>70% for all species), suggesting non-tangible benefits for participating in project activities. Other species that were not tested on-farm but grew well in the species-selection trials and were of interest to local farmers are discussed. As long as specific site and management conditions are carefully considered, data from species selection trials can be useful in informing tree planting projects with rural farmers; however, care should be taken to manage expectations.

To examine the opportunities available for designing diverse tree planting and land restoration initiatives in agricultural landscapes that contain tropical dry forests, the tree planting and protecting practices of cattle ranchers and small-scale agriculturalists were examined in two study sites in rural Panama. Ninety-nine tree species were identified that they utilize, plant, or protect on their land, the majority of which are native to Panama. The farmers had diverse reasons for maintaining trees, including improving the environment, providing food and shade for cattle, and generating a source of wood for construction, furniture, and firewood. Most of the trees mentioned in the study provide multiple uses and values and the majority of farmers wanted to plant additional trees. Some differences in species preferences and motivations for planting and protecting trees were seen between sites, thereby suggesting that land restoration and tree planting projects should be site specific. Our data indicate that there are ample opportunities to increase native tree cover in our study sites and highlight the need to incorporate farmer input into project design, implementation, and evaluation as a necessary and continuous feature throughout projects.

Reforestation in the tropics takes place across a wide variety of edaphic and climatic conditions. Reforestation trials have demonstrated that edaphic conditions may have a strong effect on species growth and survival. However it is unclear how the relative importance of soil conditions influences species survival and growth under varying amounts of rainfall and lengths of dry season. Two-year growth and mortality of 49 tree species were evaluated in four sites across Panama, representing a soil fertilityarainfall matrix. Despite strong contrasts in environmental conditions, 65% of individual species did not show consistent differences in growth between high- and low-fertility sites or between wet and dry sites. However, early growth and survival were more strongly affected by soil fertility than by rainfall patterns for the second-largest group; 30% of the species grew significantly better in both high-fertility sites than in both low-fertility sites, compared to 6% in both wet sites vs. both dry sites. In the two high-fertility sites, growth of 47% and 69% of the species was better than their across-site means. On the other hand, 55% and 73% of the species grew significantly slower than their across-site averages in the two low-fertility sites. Survival did not appear to be associated to either soil fertility or rainfall. In each site, only a few species had a significantly higher or lower within-site survival than across-site survival. Diversifying the choice of tree species increases the options for reforestation strategies that match species characteristics to local site conditions and to the objectives and management possibilities of landholders. Testing the performance of potential species under different site conditions in screening trials is paramount, both to inform selection from among the vast diversity of tree species in the tropics that show good growth and survival under different local site conditions and to filter out unsuitable species and avoid early failure of the reforestation effort.

Tropical forests provide a variety of goods and services to humanity. Although efforts to protect and manage these forests have increased in recent decades, forest loss continues. The last decade and a half has seen considerable research on reforestation with native species in Mesoamerica, including both biophysical and social aspects. Advances in knowledge have led to increasingly sophisticated reforestation treatments as well as novel ways of deriving forest goods and services from human dominated landscapes. This Special Issue includes articles produced as the result of a conference held in Panama City, Panama in January 2010 with the goal to summarize the state of knowledge of native species reforestation and associated ecosystems services in Mesoamerica. The introduction concludes with a call for continued research, including a mechanistic understanding of tree interactions with the biophysical environment in order to advance or knowledge of ecosystem services and their interactions. Results from these and other studies aimed at socioeconomic aspects of reforestation are critical to land use planning.

Few island-wide studies, however, have examined the phylogeographic history of lowland species. The objective of this study was to examine patterns of phylogeographic variation of a common and widespread New Guinean bird species (Colluricincla megarhyncha). Specifically, we test the mechanisms hypothesized to cause geographic and genetic variation (e.g., vicariance, isolation by distance and founder-effect with dispersal). To accomplish this, we surveyed three regions of the mitochondrial genome and a nuclear intron and assessed differences among 23 of the 30 described subspecies from throughout their range. We found support for eight highly divergent lineages within C. megarhyncha. Genetic lineages were found within continuous lowland habitat or on smaller islands, but all individuals within clades were not necessarily structured by predicted biogeographic barriers. There was some evidence of isolation by distance and potential founder-effects. Mitochondrial DNA sequence divergence among lineages was at a level often observed among different species or even genera of birds (5-11%), suggesting lineages within regions have been isolated for long periods of time. When topographical barriers were associated with divergence patterns, the estimated divergence date for the clade coincided with the estimated time of barrier formation. We also found that dispersal distance and range size are positively correlated across lineages. Evidence from this research suggests that different phylogeographic mechanisms concurrently structure lineages of C. megarhyncha and are not mutually exclusive. These lineages are a result of evolutionary forces acting at different temporal and spatial scales concordant with New Guinea's geological history.

During the last 2 years, however, the NMNH Paleobiology Department has collected nearly 2,800 specimens of shale in an ongoing study of the fossil insects and the habitat of this Middle Eocene deposit. Collections were acquired along the Middle Fork of the Flathead River between Paola and Coal Creeks at 15 different sites in accordance with USFS Authorization HUN281. The sedimentation planes of the oil shale are very well defined and discrete, varve-like layers of lacustrine sediment as thin as 50 mu . The shale splits into layers with smooth-surfaced mats that range in color from dark red to light yellow that provide exceptional preservation. Given the thin nature of the sediment layers, we found an expected strong bias toward the preservation of small insects. In a comparative study of the sizes of weevils (Curculionidae) in the Kishenehn and Green River collections, we observed that fewer than 1% of Green River specimens were < 2 mm in length, whereas greater than 27% of the Kishenehn specimens were < 2 mm in length. Similarly, nearly 20% of all Hymenoptera were miniscule members of the superfamily Chalcidoidea. Large insects such as Lepidoptera, Orthoptera and Odonata are extremely rare and, when present, are usually represented by isolated wings and legs. Although a number of unknown taxa exist and need to be studied in detail, representatives of only 9 insect orders presently have been found, perhaps a consequence of the bias described above. To date, 2,746 specimens of shale containing 7,432 insect fossils have been collected. The majority (55%) of the fossil insects are Diptera (true flies), with Chironomidae (midges) comprising 84% of the insects collected in this family. The remarkable qualities of the Kishenehn Basin fossil insects include the often very high quality of preservation, preservation of color, and preservation of relatively large numbers of extremely small (< 1.0 mm) insects. Exceptional preservation of this unique insect fauna will allow studies designed to identify new species of Eocene insects, resulting in more accurate definition of the ecological niches that existed along the shores of Lake Kishenehn.

We used the tree and estimates of the rate of evolution of passeriform mtDNA genes to project the nodes' ages and to assess the pattern and age of egg-rejection behavior in shrikes. Our results suggest that Lanius excubitor and L. m. meridionalis are sister taxa and that this clade is sister to L. ludovicianus, then L. sphenocercus is sister to this clade. Lanius excubitor from the Old World was considerably diverged from both New World species and part of a clade also containing four other subspecies of L. meridionalis. The paraphyly and sequence divergence between New World and Old World L. excubitor suggest that these populations represent distinct species. Mapping egg rejection onto the phylogeny suggests that rejection is deeply rooted in shrikes, as it is present as deep as two species, L. collurio and L. bucephalus, that are outgroups to the gray shrikes and in the derived L. ludovicianus. Rejection in L. ludovicianus may have been retained as long as 1.1--1.8 million years, since its clade split from the Old World L. sphenocercus, providing more evidence that once hosts evolve rejection they retain it for long periods of time. These results suggest hosts are becoming increasingly resistant to brood parasitism, which will force parasites to specialize on a few host species.

Fabrics in S-type peraluminous granites (Salihli and Turgutlu) in the detachment (Alasehir) footwall change from isotropic to protomylonitic to mylonitic towards the structure. Samples from the isotropic and protomylonitic zones were imaged in transmitted light, cathodoluminescence (CL), backscattered (BSE), and secondary electrons (SE), and show that these rocks contain abundant microcracks, and that plagioclase grains have zoning consistent with magma mixing. The granites contain fluid inclusion planes (FIPs), myrmekite replacing plagioclase, and the removal of blue luminescence in K-feldspar along microcracks and grain boundaries. Calcite and hydrous minerals commonly fill microcracks. The samples record features that formed due to (1) magma crystallization and ductile deformation (FIPs, mineral zoning), (2) changes in P and/or T (impingement and stress-induced microcracks in protomylonitic rocks), and (3) differences in intrinsic mineral properties (radial, cleavage, blunted, and deflected microcracks). Overprinted microcracks indicate exhumation during pulses. The Middle Miocene ages of these granites reported elsewhere are similar to those from large-scale extensional structures in Greece's Cycladic Massif. The Menderes and Cycladic core complexes may have developed simultaneously due to the widespread intrusion of subduction-related granitoids.

Here, we show that global MORBs yield average Fe (super 3+) /Sigma Fe ratios of 0.16+ or -0.01 (n=103), which trace back to primary MORB melts equilibrated at the conditions of the quartz-fayalite-magnetite (QFM) buffer. Our results necessitate an upward revision of the Fe (super 3+) /Sigma Fe ratios of MORBs, mantle oxygen fugacity, and the ferric iron content of the mantle relative to previous wet chemical determinations. We show that only 0.01 (absolute, or <10%) of the difference between Fe (super 3+) /Sigma Fe ratios determined by micro-colorimety and XANES can be attributed to the Mossbauer-based XANES calibration. The difference must instead derive from a bias between micro-colorimetry performed on experimental vs. natural basalts. Co-variations of Fe (super 3+) Sigma Fe ratios in global MORB with indices of low-pressure fractional crystallization are consistent with Fe (super 3+) behaving incompatibly in shallow MORB magma chambers. MORB Fe (super 3+) /Sigma Fe ratios do not, however, vary with indices of the extent of mantle melting (e.g., Na (sub 2) O(8)) or water concentration. We offer two hypotheses to explain these observations: The bulk partition coefficient of Fe (super 3+) may be higher during peridotite melting than previously thought, and may vary with temperature, or redox exchange between sulfide and sulfate species could buffer mantle melting at approximately QFM. Both explanations, in combination with the measured MORB Fe (super 3+) /Sigma Fe ratios, point to a fertile MORB source with greater than 0.3 wt.% Fe (sub 2) O (sub 3) .

Modelling approaches provide important tools for making future projections, but current models of the climate-biosphere interface remain overly simplistic, undermining the credibility of projections. We identify five ways in which substantial advances could be made in the next few years: (i) improving the accessibility and efficiency of biodiversity monitoring data, (ii) quantifying the main determinants of the sensitivity of species to climate change, (iii) incorporating community dynamics into projections of biodiversity responses, (iv) accounting for the influence of evolutionary processes on the response of species to climate change, and (v) improving the biophysical rule sets that define functional groupings of species in global models.

The deposit occurs within a stratigraphic unit that is uniquely marked by collapse features and other evidence of interior CO (sub 2) volatile release.

Although it has been suggested that the MMR marks an increase in the average energy consumption of marine animal ecosystems, this hypothesis has not been evaluated quantitatively. In this study, we integrate body size and abundance data from the fossil record with physiological data from living representatives to estimate mean per capita metabolic rates of tropical to subtropical assemblages of shallow-marine gastropods--a major component of marine ecosystems throughout the Meso-Cenozoic--both before and after the MMR. We find that mean per capita metabolic rate rose by approximately 150% between the Late Triassic and Late Cretaceous and remained relatively stable thereafter. The most important factor governing the increase in metabolic rate was an increase in mean body size. In principle, this size increase could result from secular changes in sampling and taphonomic biases, but these biases are suggested to yield decreases rather than increases in mean size. Considering that post-MMR gastropod diversity is dominated by predators, the net primary production required to supply the energetic needs of the average individual increased by substantially more than 150%. These data support the hypothesis that benthic energy budgets increased during the MMR, possibly in response to rising primary productivity.

Using the Paleobiology Database, we tabulated occurrence frequencies of genera for 48 intervals of approximately 11 Myr duration. The most frequently occurring genera, cumulatively representing 40% of occurrences in each time bin, were scored for intrinsic durability on the basis of shell size, reinforcement (ribs, folds, and spines), life habit, and mineralogy. Shell durability is positively correlated with the number of genera in a time bin, but durability traits exhibit different temporal patterns across higher taxa, with notable offsets in the timing of changes in these traits. We find no evidence for temporal decreases in durability that would indicate taphonomic bias at the Phanerozoic scale among commonly occurring genera. Also, all three groups show a remarkable stability in mean shell size through the Phanerozoic, an unlikely pattern if strong size-filtering taphonomic megabiases were affecting the fossil record of shelly faunas. Moreover, small shell sizes are attained in the early Paleozoic in brachiopods and in the latest Paleozoic in gastropods but are steady in bivalves; unreinforced shells are common to all groups across the entire Phanerozoic; organophosphatic and aragonitic shells dominate only the oldest and youngest time bins; and microstructures having high organic content are most common in the oldest time bins. In most cases, the timing of changes in durability-related traits is inconsistent with a late Mesozoic Marine Revolution. The post-Paleozoic increase in mean gastropod reinforcement occurs in the early Triassic, suggesting either an earlier appearance and expansion of durophagous predators or other drivers. Increases in shell durability hypothesized to be the result of increased predation in the late Mesozoic are not evident in the common genera examined here. Infaunal life habit does increase in the late Mesozoic, but it does not become more common than levels already attained during the Paleozoic, and only among bivalves does the elevated late Mesozoic level persist through the Holocene. These temporal patterns suggest control on the occurrence of durability-related traits by individual evolutionary histories rather than taphonomic megabiases. Our findings do not mean taphonomic biases are absent from the fossil record, but rather that their effects apparently have had little net effect on the relative occurrence of shell traits generally thought to confer higher preservation potential over long time scales.

In addition to this novel evolutionary component, Darwin's species concept also retained an older taxonomic component, namely the view that the species category is a taxonomic rank; moreover, he adopted amount of difference as a criterion for ranking lineages as species. Subsequent biologists retained both components of Darwin's species concept, although they replaced Darwin's ranking criterion with ranking criteria that either are more objectively defined or relate more directly to the biological bases of lineage separation and divergence. Numerous alternative ranking criteria were proposed, resulting in a proliferation of species definitions and a controversy concerning the concept of species. That controversy can be resolved by distinguishing more explicitly between the theoretical concept of species and the operational criteria that are used to apply the concept in practice. By viewing the various alternative ranking criteria as operational indicators of lineage separation rather than necessary properties of species, the conflicts among competing species concepts are eliminated, resulting in a unified concept of species. A brief examination of the history of biology reveals that an important shift related to the unified species concept has been emerging ever since Darwin reformulated the concept of species with an evolutionary basis. The species category is effectively being decoupled from the hierarchy of taxonomic ranks and transferred to the hierarchy of biological organization. Published 2011.

Consistent with Article 73.2.3 of the International Code of Zoological Nomenclature (Anonymous 1999), the Syntype specimens of C. modesta originated from two localities and thus the type locality encompasses all of the places of origin. Moore (1898) synonomized C. modesta with the European Helobdella stagnalis (Linnaeus 1758) based on similarities in morphology. Subsequently, all North American leeches with a nuchal scute were considered as H. stagnalis with the exception of Helobdella californica Kutschera 1988, known only from Stow Lake, Golden Gate Park, San Francisco, California, USA. In addition to Europe and North America, Helobdella stagnalis has been reported from South America, Africa, and Asia (Sawyer 1986).

Such concerns have been reinforced by numerous studies that found correlations between measures of sampling intensity and observed diversity. However, correlation does not necessarily mean that sampling controls observed diversity: an alternative view is that both sampling and diversity may be driven by some common factor (e.g. variation in continental flooding driven by sea level). The latter is known as the "common cause" hypothesis. Here, we present quantitative analyses of the relationships between dinosaur diversity, sampling of the dinosaur fossil record, and changes in continental flooding and sea level, providing new insights into terrestrial common cause. Although raw data show significant correlations between continental flooding/sea level and both observed diversity and sampling, these correlations do not survive detrending or removal of short-term autocorrelation. By contrast, the strong correlation between diversity and sampling is robust to various data transformations. Correlations between continental flooding/sea level and taxic diversity/sampling result from a shared upward trend in all data series, and short-term changes in continental flooding/sea level and diversity/sampling do not correlate. The hypothesis that global dinosaur diversity is tied to sea-level fluctuations is poorly supported, and terrestrial common cause is unsubstantiated as currently conceived. Instead, we consider variation in sampling to be the preferred null hypothesis for short-term diversity variation in the Mesozoic terrestrial realm.

These data mimic what we will see when we point next-generation space telescopes at nearby exoplanets. We use principal component analysis (PCA) and rotational light curve inversion to characterize color inhomogeneities and map their spatial distribution from these unusual vantage points, as a complement to the equatorial views presented by Cowan et al. in 2009. We also perform the same PCA on a suite of simulated rotational multi-band light curves from NASA's Virtual Planetary Laboratory three-dimensional spectral Earth model. This numerical experiment allows us to understand what sorts of surface features PCA can robustly identify. We find that the EPOXI polar observations have similar broadband colors as the equatorial Earth, but with 20%-30% greater apparent albedo. This is because the polar observations are most sensitive to mid-latitudes, which tend to be more cloudy than the equatorial latitudes emphasized by the original EPOXI Earth observations. The cloudiness of the mid-latitudes also manifests itself in the form of increased variability at short wavelengths in the polar observations and as a dominant gray eigencolor in the south polar observation. We construct a simple reflectance model for a snowball Earth. By construction, our model has a higher Bond albedo than the modern Earth; its surface albedo is so high that Rayleigh scattering does not noticeably affect its spectrum. The rotational color variations occur at short wavelengths due to the large contrast between glacier ice and bare land in those wavebands. Thus, we find that both the broadband colors and diurnal color variations of such a planet would be easily distinguishable from the modern-day Earth, regardless of viewing angle.

Under this model, dispersal allegedly inhibited dinosaurian diversification, while vicariance and local extinction enhanced it. However, apomorphy-based analyses of the known fossil record indicate that sauropodomorphs were absent in North America until the Early Jurassic, reframing the temporal context of their arrival. We describe a new taxon from the Kayenta Formation of Arizona that comprises the third diagnosable sauropodomorph from the Early Jurassic of North America. We analysed its relationships to test whether sauropodomorphs reached North America in a single sweepstakes event or in separate dispersals. Our finding of separate arrivals by all three taxa suggests dispersal as a chief factor in dinosaurian diversification during at least the early Mesozoic. It questions whether a "cosmopolitan" dinosaur fauna ever existed, and corroborates that vicariance, extinction and dispersal did not operate uniformly in time or under uniform conditions during the Mesozoic. Their relative importance is best measured in narrow time slices and circumscribed geographical regions.

Diptera includes species known for their ubiquity (Musca domestica house fly), their role as pests (Anopheles gambiae malaria mosquito), and their value as model organisms across the biological sciences (Drosophila melanogaster). A resolved phylogeny for flies provides a framework for genomic, developmental, and evolutionary studies by facilitating comparisons across model organisms, yet recent research has suggested that fly relationships have been obscured by multiple episodes of rapid diversification. We provide a phylogenomic estimate of fly relationships based on molecules and morphology from 149 of 157 families, including 30 kb from 14 nuclear loci and complete mitochondrial genomes combined with 371 morphological characters. Multiple analyses show support for traditional groups (Brachycera, Cyclorrhapha, and Schizophora) and corroborate contentious findings, such as the anomalous Deuterophlebiidae as the sister group to all remaining Diptera. Our findings reveal that the closest relatives of the Drosophilidae are highly modified parasites (including the wingless Braulidae) of bees and other insects. Furthermore, we use micro-RNAs to resolve a node with implications for the evolution of embryonic development in Diptera. We demonstrate that flies experienced three episodes of rapid radiation-lower Diptera (220 Ma), lower Brachycera (180 Ma), and Schizophora (65 Ma)-and a number of life history transitions to hematophagy, phytophagy, and parasitism in the history of fly evolution over 260 million y.

We assessed the composition of soil organic phosphorus in 19 contrasting soils under lowland tropical forest in the Republic of Panama using NaOH-EDTA extraction and solution super(31)P nuclear magnetic resonance spectroscopy. The soils spanned a strong rainfall gradient (1730-3404mmy super(-1)) and contained a wide range of chemical properties (pH 3.3-7.0; total carbon 2.8-10.4%; total phosphorus 74-1650mgPkg super(-1)). Soil organic phosphorus concentrations ranged between 22 and 494mgPkg super(-1) and were correlated positively with total soil phosphorus, pH, and total carbon, but not with annual rainfall. Organic phosphorus constituted 26 plus or minus 1% (mean plus or minus STD error, n=19) of the total phosphorus, suggesting that this represents a broad emergent property of tropical forest soils. Organic phosphorus occurred mainly as phosphate monoesters (68-96% of total organic phosphorus) with smaller concentrations of phosphate diesters in the form of DNA (4-32% of total organic phosphorus). Phosphonates, which contain a direct carbon-phosphorus bond, were detected in only two soils (3% of the organic phosphorus), while pyrophosphate, an inorganic polyphosphate with a chain length of two, was detected in all soils at concentrations up to 13mgPkg super(-1) (3-13% of extracted inorganic phosphorus). Phosphate monoesters were a greater proportion of the total organic phosphorus in neutral soils with high concentrations of phosphorus and organic matter, whereas the proportion of phosphate diesters was greater in very acidic soils low in phosphorus and organic matter. Most soils did not contain detectable concentrations of either myo- or scyllo-inositol hexakisphosphate, which is in marked contrast to many temperate mineral soils that contain abundant inositol phosphates. We conclude that soil properties exert a strong control on the amounts and forms of soil organic phosphorus in tropical rain forests, but that the proportion of the total phosphorus in organic forms is relatively insensitive to variation in climate and soil properties. Further work is now required to assess the contribution of soil organic phosphorus to the nutrition and diversity of plants in these species-rich ecosystems.

The TM uses coastal area and seawater temperature over Pleistocene time to reveal long-term climate/ area clusters that predict biogeographic regions. An earlier study with the TM predicted 20 of 24 classical biogeographic regions; the 4 omitted regions were either weak, disputed, or structurally (sandy/silty regions) inapplicable to the TM. The TM predicted a new western North Atlantic Subarctic Region, centered on the Strait of Belle Isle and lying between Newfoundland and Labrador. In contrast, Nova Scotia and the Gulf of Maine were found to be a Boreal/Subarctic transition zone. The predictions of the TM were earlier supported with coralline algal abundances, and here are supported by a test with macrophyte assemblages.

Zenaida aurita. These occur in deposits dating to about 55,000 to 28,000 years ago that formed during the last glacial period when the land area of Bermuda was much larger. At that time, the West Indies would have been a much more likely source area than eastern North America for dove as a potential colonist of Bermuda. The Bermuda dove appears to have been a resident and perhaps became extinct as a result of flooding of the Bermuda platform and reduction in land area during the present interglacial. The two doves found on Bermuda today (Mourning Dove Zenaida macroura and Common Ground Dove Columbina passerina) are absent in the fossil record and apparently did not become established on the island until after human settlement in the seventeenth century.

When animals consume quickly eaten food items, individuals located at the front edge of a group typically have greater foraging success. When groups feed at large clumped resources, dominant individuals can often monopolize the resource, leading to higher feeding success in the center of the group. In order to test these predictions, behavioral data relating foraging success to within-group spatial position were recorded from two habituated groups of ring-tailed coatis (Nasua nasua) in Iguazu, Argentina. Foraging success did not fit expected patterns. When feeding on small ground litter invertebrates, coatis had the same foraging success at all spatial positions. This pattern likely resulted from an abundance of invertebrates in the ground litter. When feeding on fruit, individuals in the front of the group had greater feeding success, which was driven by the relatively quick depletion of fruit trees. Dominant juveniles were often located in the front of the group which led to increased access to food. This resulted in higher feeding success on fruits but simultaneously increased their risk of predation. Although groups typically became more elongated and traveled faster when feeding on fruit, it did not appear that the coatis were drastically changing their spacing strategies when switching between the two food types. Paradoxically, spatial position preferences during invertebrate foraging appeared to be driven by fruit trees. Because fruit trees were encountered so frequently, juveniles ranging at the front edge of the group during invertebrate foraging were the first to arrive at fruit trees and thus had higher foraging success. This study demonstrates the importance of how food patch size and depletion rate affect the spatial preferences of individuals.

However, spatial heterogeneity is not static and it can change along temporal scales. These changes, whether gradual or rapid, have the potential of forcing species extinctions or facilitating the introduction of nonnative species. Here, we present modeling results that show how changes in spatial heterogeneity over several generations can produce strong changes in benthic species composition residing in eastern Long Island Sound, USA. For many benthic species, hard substrate is a limiting resource which can vary in availability among different coastal areas. We modeled gradual changes from a heterogeneous landscape (mimicking patches of natural hard and soft substrate) to a homogenous one (analogous to a fully developed coast with hard, manmade substrate) and followed the abundance and distribution patterns of species possessing four different life histories. We also modeled changes from homogeneous to heterogeneous landscapes. We found that as regions become more homogeneous, species extinctions become more frequent and poor dispersers dominate locally. In contrast, as habitats become more heterogeneous, species distributing across localities leads to regional species coexistence and fewer extinctions. These results suggest that focusing on changing habitat heterogeneity can be a useful management strategy to prevent poor dispersing species, such as invasive ascidians, from driving communities to monocultures.

An Elsec 764 hand-held light meter was used to record the light intensity falling on collection material held within and without V-shaped book mounts and with sequential lights turned on, as occurs in collections' use. The authors developed a simple algebraic formula to calculate cumulative doses of light and incident ultraviolet radiation to determine how many hours collection material could be accessed and illuminated before damage could be expected. The authors calculated the maximum cumulative doses possible based on numbers of access hours and compared these to recommended doses for sensitive media as a monitoring strategy for the long-term preservation of light sensitive special collection materials. The results from this study suggest that the light levels evaluated are not in excess of recommended values and that the use of book mounts reduces the amount of light falling on collection material. Monitoring actions are recommended for institutions wishing to replicate the study. Adapted from the source document.

Studies of recently diverged taxa utilizing both mitochondrial and nuclear data sets may therefore yield gene trees with differing levels of phylogenetic signal as a result of differences in coalescence times. However, several factors can lead to this same pattern, and it is important to distinguish between them to gain a better understanding of the process of divergence and the factors driving it. Here, we employ three nuclear intron loci in addition to the mitochondrial Cytochrome b gene to investigate the magnitude and timing of divergence between two endangered and nearly indistinguishable petrel taxa: the Galapagos (GAPE) and Hawaiian (HAPE) petrels (Pterodroma phaeopygia and P. sandwichensis). Phylogenetic analyses indicated reciprocal monophyly between these two taxa for the mitochondrial data set, but trees derived from the nuclear introns were unresolved. Coalescent analyses revealed effectively no migration between GAPE and HAPE over the last 100000 generations and that they diverged relatively recently, approximately 550000years ago, coincident with a time of intense ecological change in both the Galapagos and Hawaiian archipelagoes. This indicates that recent divergence and incomplete lineage sorting are causing the difference in the strength of the phylogenetic signal of each data set, instead of insufficient variability or ongoing male-biased dispersal. Further coalescent analyses show that gene flow is low even between islands within each archipelago suggesting that divergence may be continuing at a local scale. Accurately identifying recently isolated taxa is becoming increasingly important as many clearly recognizable species are already threatened by extinction.

The current consensus taxonomy of S. camelus names five subspecies based on morphology, geographic range, mtDNA restriction fragment length polymorphism and mtDNA-CR sequence analysis: S. c. camelus, S. c. syriacus, S. c. molybdephanes, S. c. massaicus and S. c. australis. We expanded a previous mtDNA dataset from 18 individual mtDNA-CR sequences to 123 sequences, including sequences from all five subspecies. Importantly, these additional sequences included 43 novel sequences of the red-necked ostrich, S. c. camelus, obtained from birds from Niger. Phylogeographic reconstruction of these sequences matches previous results, with three well-supported clades containing S. c. camelus/syriacus, S. c. molybdophanes, and S. c. massaicus/australis, respectively. The 14 microsatellite loci assessed for 119 individuals of four subspecies (all but S. c. syriacus) showed considerable variation, with an average of 13.4 ( plus or minus 2.0) alleles per locus and a mean observed heterozygosity of 55.7 ( plus or minus 5.3)%. These data revealed high levels of variation within most subspecies, and a structure analysis revealed strong separation between each of the four subspecies. The level of divergence across both marker types suggests the consideration of separate species status for S. c. molybdophanes, and perhaps also for S. c. camelus/syriacus. Both the mtDNA-CR and microsatellite analyzes also suggest that there has been no recent hybridization between the subspecies. These findings are of importance for management of the highly endangered red-necked subspecies (S. c. camelus) and may warrant its placement onto the IUCN red list of threatened animals.

Using extensive demographic and genetic data, we investigated the relationships among pedigree inbreeding coefficients, metrics of molecular heterozygosity and fitness for a large population of endangered African wild dogs (Lycaon pictus) in South Africa. Molecular metrics based on 19 microsatellite loci were significantly, but modestly correlated to inbreeding coefficients in this population. Inbred wild dogs with inbreeding coefficients of greater than or equal to 0.25 and subordinate individuals had shorter lifespans than outbred and dominant contemporaries, suggesting some deleterious effects of inbreeding. However, this trend was confounded by pack-specific effects as many inbred individuals originated from a single large pack. Despite wild dogs being endangered and existing in small populations, findings within our sample population indicated that molecular metrics were not robust predictors in models of fitness based on breeding pack formation, dominance, reproductive success or lifespan of individuals. Nonetheless, our approach has generated a vital database for future comparative studies to examine these relationships over longer periods of time. Such detailed assessments are essential given knowledge that wild canids can be highly vulnerable to inbreeding effects over a few short generations.

Here we report a unique occurrence of seasonally dry vegetation, preserved in growth position along >5 km of strike, in the Pennsylvanian (early Kasimovian, Missourian) of New Mexico (United States). Analyses of stump anatomy, diameter, and spatial density, coupled with observations of vascular traces and associated megaflora, show that this was a deciduous, mixed-age, coniferopsid woodland ( approximately 100 trees per hectare) with an open canopy. The coniferopsids colonized coastal sabkha facies and show tree rings, confirming growth under seasonally dry conditions. Such woodlands probably served as the source of coniferopsids that replaced Coal Forests farther east in central Pangea during drier climate phases. Thus, the newly discovered woodland helps unravel biome-scale vegetation dynamics and allows calibration of climate models.

Here we report geoarchaeological evidence of increasing floodplain sedimentation and prehistoric land-use intensification in the Delaware River Valley (eastern United States) during the Medieval Climate Anomaly-Little Ice Age transition. The evidence of this anthropogenic sedimentation event, documented throughout eastern North America, is designated here as pre-colonial sediment (PCS), ca. A.D. 1100-1600.

Consideration of the decomposition equation for species richness, S, evenness, E, and the Shannon estimate of entropy or information, H, plus their respective regressions on the accumulation of the number of individuals, N, in a sample leads to the establishment of three structural types. Each type is defined by the slope, beta (sub 1H) , of the regression H versus lnN and depends on the accumulation rate of species between samples (beta-diversity) in a community. These types are designated as 1) Type 0, where H is constant with the accumulation of lnN denoting equilibrium or stability (Log series is a special case); 2) Type 1, where the slope of H is positive with the accumulation of lnN denoting growth or expansion (Log normal is a special case); and 3) Type -1, where the slope of H is negative with the accumulation of lnN denoting decline, instability or stress. In this study, 72 communities were analyzed from environments ranging from marginal marine to the abyss. Only 10 communities are identified as type -1 with the majority of these at lower bathyal and abyssal depths. At abyssal depths the average beta (sub 1H) is -0.057 and data from fossil communities in the Arctic indicate that this unstable, stressed situation has persisted for at least 50 ka. In the Gulf of Mexico at shelf depths, low values for beta (sub 1H) are registered near the Mississippi delta. In contrast, the open-ocean east of New Zealand has an average beta (sub 1H) of 0.227, the highest recorded. Among marginal marine environments an average beta (sub 1H) of -0.030 was recorded in Long Island Sound before the collapse of that community. In contrast, the Indian River Lagoon, Florida had the highest beta (sub 1H) for a marginal marine environment with an average value of 0.195. No simple invariant pattern between type 0 and type 1 communities is prevalent in any environment. Overall 31 communities are type 0 and 31 are type 1. In marginal marine environments (22 communities) the average value of beta (sub 1H) is 0.092. In the open-ocean (50 communities) the average value of beta (sub 1H) is 0.093. Evidently, for any group to remain highly successful on the average a slightly positive value of beta (sub 1H) is required.

This study revealed that two symmetry-related D(H) positions are located approximately 1 Aa above and below the midpoint between the split O interlayer sites in Na-birnessite. This result confirms our earlier interpretation that the split interlayer sites include O atoms from two symmetrically equivalent H (sub 2) O molecules. These molecules are oriented 180 degrees to each other, and they are pivoted about a single set of H(D) atoms positions. The interlayer H (sub 2) O molecules in K-birnessite are oriented such that one of the H(D) atoms is pointed approximately toward the Mn octahedral layer O atoms and the other is directed approximately within the net of interlayer K/O sites. In K-birnessite, six K-O (sub oct) distances are shorter than 3.35 Aa, compared with only two Na-O (sub oct) bond lengths in Na-birnessite, suggesting that K cations are more tightly bonded to the octahedral O atoms than are Na cations.

Analysis of variance (ANOVA) was used to investigate the differences in mean proportions for six species (Miliammina fusca, Trochammina inflata, Arenoparrella mexicana, Tiphotrocha comprimata, Haplophragmoides wilberti and Jadammina macrescens) selected because of their importance in distinguishing assemblages across salt marshes in the study region. As expected, ANOVA's on all species indicated significant differences among low-, middle-, and high-marsh zones defined by their flora. No significant differences were found between stations in the low- and high-marsh indicating homogeneity in these zones. In contrast, for all six species in the middle-marsh zone, significant outcomes for ANOVA, cluster analysis and post-hoc comparisons suggested that the middle-marsh should be divided into two zones. In addition, two species exhibited a patchy (inhomogeneous) distribution among all stations in the middle marsh. If confirmed by additional studies, our results indicate that sampling of modern salt-marshes to document the distribution of foraminifera for use in sea-level reconstructions should recognize the spatial variability associated with the middle-marsh floral zone.

Montane Neotropical hummingbirds are expected to shift altitudinally upwards in response to climate change to track their ancestral climatic regime, which is predicted to influence their flight performance. In this study, we use the climate envelope approach to estimate upward elevational shifts for five Andean hummingbird species under two climate change scenarios. We then use field-based data on hummingbird flight mechanics to estimate the resulting impact of climate change on aerodynamic performance in hovering flight. Our results show that in addition to significant habitat loss and fragmentation, projected upwards elevational shifts vary between 300 and 700m, depending on climate change scenario and original mean elevation of the target species. Biomechanical analysis indicates that such upwards elevational shifts would yield a similar to 2-5 degree increase in wing stroke amplitude with no substantial effect on wingbeat frequency. Overall, the physiological impact of elevational shifts of <1000m in response to climate change is likely to be small relative to other factors such as habitat loss, changes in floristic composition, and increased interspecific competition.

Efforts to find and select suitable targets (plus backup targets) are severely hampered by our lack of knowledge of the physical properties of dynamically favorable NEOs. In particular, current mission scenarios tend to favor primitive low-albedo objects. For the vast majority of NEOs, the albedo is unknown. Here we report new constraints on the size and albedo of 65 NEOs with rendezvous Delta v <7 km s (super -1) . Our results are based on thermal-IR flux data obtained in the framework of our ongoing (2009-2011) ExploreNEOs survey using NASA's "Warm-Spitzer" space telescope. As of 2010 July 14, we have results for 293 objects in hand (including the 65 low-Delta v NEOs presented here); before the end of 2011, we expect to have measured the size and albedo of approximately 700 NEOs (including probably approximately 160 low-Delta v NEOs). While there are reasons to believe that primitive volatile-rich materials are universally low in albedo, the converse need not be true: the orbital evolution of some dark objects likely has caused them to lose their volatiles by coming too close to the Sun. For all our targets, we give the closest perihelion distance they are likely to have reached (using orbital integrations from Marchi et al. 2009) and corresponding upper limits on the past surface temperature. Low-Delta v objects for which both albedo and thermal history may suggest a primitive composition include (162998) 2001 SK162, (68372) 2001 PM9, and (100085) 1992 UY4. Copyright (Copyright) 2011.

Case study examples, mostly drawn from North America, are presented for each of the six general categories of human niche construction. These empirically documented categories of ecosystem engineering form the basis for a predictive model that outlines potential general principles and commonalities in how small-scale human societies worldwide have modified and manipulated their 'natural' landscapes throughout the Holocene.

The model is based on a linear combination of stochastic processes and is also the solution to the linear diffusion equation perturbed by a spatially correlated noise field. This allows flexible modeling of the power spectral density (PSD), and we derive the likelihood function for the process, enabling one to estimate the parameters of the process, including break frequencies in the PSD. Our statistical technique is computationally efficient, unbiased by aliasing and red noise leak, and fully accounts for irregular sampling and measurement errors. We show that our stochastic model provides a good approximation to the X-ray light curves of galactic black holes, and the optical and X-ray light curves of active galactic nuclei (AGNs). We use the estimated timescales of our stochastic model to recover the correlation between characteristic timescale of the high-frequency X-ray fluctuations and black hole mass for AGNs, including two new 'detections' of the timescale for Fairall 9 and NGC 5548. We find a tight anti-correlation between the black hole mass and the amplitude of the driving noise field, which is proportional to the amplitude of the high-frequency X-ray PSD, and we estimate that this parameter gives black hole mass estimates to within ~0.2 dex precision, potentially the most accurate method for AGNs yet. We also find evidence that 13% of AGN optical PSDs fall off flatter than 1/f 2 and, similar to previous work, find that the optical fluctuations are more suppressed on short timescales compared to the X-rays, but are larger on long timescales, suggesting that the optical fluctuations are not solely due to reprocessing of X-rays.

Here, we examine phylogeographic patterns of the species' populations in the North Atlantic and one remote Mediterranean population using sequence variation in a fragment of the mitochondrial cytochrome b gene (607 bp). We found that, as opposed to many other rocky intertidal species, L. saxatilis has likely had a long and continuous history in the Northwest Atlantic, including survival during the last glacial maximum (LGM), possibly in two refugia. In the Northeast Atlantic, several areas likely harboured refugial populations that recolonized different parts of this region after glacial retreat, resulting in strong population structure. However, the outlying monomorphic Venetian population is likely a recent anthropogenic introduction from northern Europe and not a remnant of an earlier wider distribution in the Mediterranean Sea. Overall, our detailed phylogeography of L. saxatilis adds an important piece to the understanding of Pleistocene history in North Atlantic marine biota as well as being the first study to describe the species' evolutionary history in its natural range. The latter contribution is noteworthy because the snail has recently become an important model species for understanding evolutionary processes of speciation; thus our work provides integral information for such endeavours.

Using the Spitzer Space Telescope, we detected a Class 0 and a Class II object in one of these, CB130-1. The observed photometric data from Spitzer and ground-based telescopes are used to establish the physical parameters of the Class 0 object. Spectral energy distribution fitting with a radiative transfer model shows that the luminosity of the Class 0 object is 0.14-0.16 L (sub []) , which is low for a protostellar object. In order to constrain the chemical characteristics of the core having the low-luminosity object, we compare our molecular line observations to models of lines including abundance variations. We tested both ad hoc step function abundance models and a series of self-consistent chemical evolution models. In the chemical evolution models, we consider a continuous accretion model and an episodic accretion model to explore how variable luminosity affects the chemistry. The step function abundance models can match observed lines reasonably well. The best-fitting chemical evolution model requires episodic accretion and the formation of CO (sub 2) ice from CO ice during the low-luminosity periods. This process removes C from the gas phase, providing a much improved fit to the observed gas-phase molecular lines and the CO (sub 2) ice absorption feature. Based on the chemical model result, the low luminosity of CB130-1 is explained better as a quiescent stage between episodic accretion bursts rather than being at the first hydrostatic core stage.

Dunkard Group consists of the Waynesburg, Washington, and Greene Formations. Allocyclic processes in a continental basin controlled the stratigraphy of the Dunkard Group. Variations in precipitation controlled variations in the following: 1) terrestrial organic productivity, 2) lacustrine base levels, 3) basin weathering, 4) pedogenesis, 5) sediment supply, and 6) sedimentary geochemistry. Tectonics controlled accommodation space whereas eustasy was of little consequence. Paleosols, delineating regional unconformities, show a gradual upward transition from humid climate underclay paleosols in the late Pennsylvanian Monongahela Group to petroclacic paleosols indicative of climate drying during deposition of Dunkard strata. As in the Monongahela Group, the Waynesburg and Washington Formations contain multi-bedded nonmarine lacustrine limestones with subareal exposure features that grade laterally into petroclacic paleo-Vertisols. Subareal exposure features are uncommon in decimeter-scale micritic limestones in the Greene Fm; equivalent up-dip paleosols have been lost to erosion. Coal bed continuity, thickness, and quality, also decrease up-section where thin (cm scale) coal beds unconformably overlie the paleosol/underclay/limestone complexes in the Greene Fm. Lacustrine shales and impure fluvio-lacustrine sandstones, commonly with a weak pedogenic overprint, overly coal bed horizons. Unconformities at the tops of multiple regional paleosols, overlain by lacustrine strata, suggest repeated rise and fall of lacustrine conditions on a fan-delta in a basin perhaps analogous to the Okavango basin and fan in Namibia, southern Africa. During maximum lake levels, progradation of fluvio-deltaic systems resulted in laminated shale conformably overlain by flat-bottomed distributary mouth bar siltstones and sandstones. Prograding distributaries and/or fluvial channels subsequently incised the flat-bottom mouth bar sands. During low lake levels, anastomosing fluvial systems marked by a weak pedogenic overprint spread across a low gradient ( approximately 20cm/Km) fan surface. Deposition of Dunkard strata appears to have been coeval with at least part of the 10 My transition from relatively humid conditions in the Late Pennsylvanian to Middle Permian aridity in North America.

This report documents the palynology, petrography, and geochemistry of some of these coal beds, in an effort to better discern the nature of the paleomires these coal beds were derived from. Palynologically, all of the Dunkard coals are dominated by tree fern spore taxa, namely Punctatisporites minutus, Punctatosporites minutus, Laevigatosporites minutes, and hymospora spp. Calamite spores, mainly Calamospora and Laevigatosporites spp., are subdominant in some samples. Cordaite and pteridosperm pollen, Florinites and Vesicaspora respectively, occur consistently, but in minor amounts. Other gymnosperous pollen, Pityosporites and bisaccate-striate genera (e.g., Hamiapollenites, Striatopodocarpites, Protohaploxypinus) occur sporadically. Collectively, Dunkard coal spore/pollen assemblages are indistinguishable from underlying Monongahela Group coal palynofloras. Petrographically, Dunkard coal beds are largely dominated by vitrinite macerals, with relatively minor amounts of liptinite and inertinite macerals. This type of maceral distribution is also very similar to that of Monongahela Group coal beds. Geochemically, Dunkard Group coals are highly impure, containing high amounts of ash (> or = 25 percent) and sulfur (> or = 3 percent). By contrast, mineable Monongahela Group coal beds are lower in both ash (< or = 15 percent) and sulfur (< or = 3 percent). Based on the three sets of data, Dunkard Group coal beds are interpreted to have formed in small, discontinuous mires that were dominated by tree ferns with subdominant calamites. The mires were planar and topogenous, which resulted in coal beds with high ash and sulfur contents. The thin nature and ephemeral occurrence of Dunkard coal beds is most likely the result of a "drying" trend in the Late Pennsylvanian/Permian, which greatly curtailed the availability of moisture necessary for the more extensive peat formation observed in the underlying Monongahela Group.

Dunkard Groups, central Appalachian Basin, indicate that these limestones are dominated by ostracod-peloidal, muddy carbonates with trace to moderate amounts of siliciclastic clay and silt. Limestones range from laminated wackestones with abundant articulated ostracods and phosphatic fish teeth and spine fragments to highly bioturbated wackestones and packstones dominated by disarticulated ostracod shells. In some, ostracods are concentrated into "shell-bed" pavements intercalated with mudstone to wackestone laminae. Nested ostracod shells, similar to those inferred from the fossil record to have formed in low-energy estuaries or lagoons, are common. Overall, very low diversity ostracod assemblages within micritic limestones that exhibit minimal evidence of transportation suggest deposition under non-marine to very low salinity conditions in quiet water environments- the abundance of carbonate peloids in the Waynesburg and Washington Fm limestones suggest warm shallow waters within the photic zone. Greene Formation limestones exhibit evidence for formation under deeper water conditions. Early diagenetic glauconite cements occur in the Benwood limestone between moderately to uncompacted fish fragments. The presence of pre-compaction glauconite suggests reduced pore waters during early burial in organic-rich sediments and overall low sedimentation rates, which are requisite for glauconite mineral precipitation. Although glauconite cements can indicate brackish to marine waters, they could alternatively indicate alkaline lacustrine conditions during Benwood deposition, consistent with paleocologic and sedimentologic characteristics. Several limestones in the Dunkard Gp. (e.g., Redstone, Waynesburg and Windy Gap limestones) contain rhizoliths and elongated to vuggy secondary porosity, lined with micritic cements, nonluminescent calcite cements and rare geopetal silts. These features along with microbrecciation indicate periodic exposure of Monongahela and Dunkard limestones that led to vadose diagenesis and incipient soil formation.

These regions were in the western part of Pangaea. All contain paleofloras that are, on average, of mixed wetland and dryland composition. Detailed outcrop study, however, indicates spatial and/or temporal separation of these floras. This probably reflects a combination of moisture variation during glacial-interglacial cycles and overall drier climates in western parts of the supercontinent. Both New Mexico and Utah essentially lack organic-rich deposits of Pennsylvanian-Permian transitional age. In New Mexico, mixed floras from floodplain deposits suggest landscape complexity, and give way to fully "Permian-type" assemblages (conifers, cordaitaleans, callipterids) during the latest Pennsylvanian. In Utah, slightly further north of the paleoequator, mixed floras, similar to those of New Mexico, are confined to floodplain complexes sandwiched between eolian dune sands. Further eastward in Texas peat swamps and associated wet floodplains persisted nearly to the end of the Pennsylvanian. These are intercalated with deposits bearing xeromorphic "Permian-type" flora that become dominant in Early Permian deposits, coincident with the disappearance of organic-rich beds. By comparison, the approximately coeval Dunkard succession was more consistently "wet" throughout this entire transition, reflecting a strong west-east climate gradient north of the central Pangaean mountain ranges. Causes of the west-to-east climate gradient appear to have a complex cause, presently incompletely understood.

Extant raninoids inhabit tropical and temperate marine waters, and are widespread along a wide bathymetric range (from approximately 5 to 1000 m depth). Although their appearance seems primitive and aberrant, some authors consider their morphology to be an advanced (derived) adaptation to their burrowing lifestyle. This combination of primitive and derived traits makes them a phylogenetically controversial clade. Thus, knowledge of ancient raninoids is important for understanding taxonomic relationships among the principal crab groups: Dromiacea (sponge crabs) and Eubrachyura ("higher" crabs), since frog crabs occupy an intermediate position. The oldest known frog crabs appeared during Albian times ( approximately 100 M.y) and experienced a rapid diversification during the Cretaceous ( approximately 100 to 65 M.y.). While Cretaceous raninoid taxa from higher latitudes are well known, records from tropical South America are scarce. The general lack of knowledge of crustacean paleontology from the Neotropics may result in considerable biases when attempting to address major evolutionary, biogeographic and phylogenetic questions. Recently, seven species (five new) of raninoid and raninoid-like faunas, arrayed in five genera, four families, and two superfamilies, have been collected in Cretaceous (Albian-Maastrichtian) rocks from Colombia, South America. These new findings represent some of the oldest (or even the oldest) records for their lineages, calling for re-evaluations of their spatio-temporal patterns, in order to gain a more accurate understanding of the role of the Neotropics on the diversity, origins and macroevolutionary patterns of primitive brachyuran crabs throughout time.

A cart is provided with an elevated sign stating "The Scientist Is In" and touchable objects are chosen by the scientist. The venue is advertised in the museum's quarterly calendar and on NMNH's websites where a biography of the scientist is listed. This program has proven to be an effective means of communicating science to the general public and provides an opportunity for visitors to ask questions and personally interact with the scientist. A single two hour session had over three hundred visitors including school groups (K-16) and interested families and individuals. This can be a new experience for scientists who are often more comfortable presenting scientific talks to their peers. The interactions with the public are informal and spontaneous. One needs to be prepared for not only all ages and varying levels of interest, knowledge and understanding but also for letting visitors take the lead in asking questions. Since personal contact time is limited and we won't be interacting with these individuals again, we try to refer them to related exhibits in the museum and to relevant NMNH websites. Visitors benefit because they are taking the initiative to find out more about a topic on their own. The public frequently gives positive feedback about the opportunity to meet research scientists and handle items they would not normally be allowed to touch in the museum. Some scientists include a brief video of field work. Specific examples will be given relating to a cart developed by the authors which contains Holocene and fossil mollusks.

During the Late Triassic (Carnian, ca. 225 Ma), a major radiation of insect endophytic herbivores, following the end-Permian crisis, have been documented for the Molteno Formation of the Karoo Basin. The monospecific consumption of particular plant species, organs and tissues by herbivore specialists is analogous to the colonization of angiosperms by a more modern spectrum of insect herbivores about 100 million years later. From the late Middle Jurassic (Bathonian-Callovian boundary, ca. 165 Ma), additional evidence for diverse associations is recorded from the Jiulongshan Formation of Inner Mongolia, in northeastern China. In these deposits, as in the Molteno Biome, a considerable amount of external foliage feeding, piercing-and-sucking, oviposition, leaf mining, galling, seed predation, wood boring and pollinator activity characterize a highly diverse flora consisting of cycads, ginkgophytes, bennettitaleans, pentoxylaleans, seed-ferns, and gnetophytes. These activities occurred in lakeshore woodland environments and represent a major diversification on extinct plant clades of insect basal lineages that remain today. By the mid Early Cretaceous (late Barremian, ca. 125 Ma), there is an extension of insect herbivory and pollination associations that are indicated by the Yixian Formation in Liaoning, northeastern China. This deposit signals one of the earliest known floras harboring a few basal angiosperm taxa, but is overwhelmingly dominated by ferns and gymnosperms, where virtually all of the herbivore and pollinator activity resided. Interestingly, although this flora was diverse and contains such specialized associations as beetle leaf mines on the broadleaved conifer Liaoningocladus and globular galls on bennettitalean foliage, it nevertheless represents a reduction of herbivorous associations from Middle Jurassic times. These three, mid Mesozoic deposits represent a significant heightening of plant-insect associational diversity from the Paleozoic and record levels ecologically equivalent to angiosperms and their insect herbivores and pollinators.

AN - 928892674; 2012-031345 AB - Shallow marine sediments of the Miocene Chesapeake Group crop out along the Calvert Cliffs, a ca. 50 km long series of ca. 10-40 m high eroding bluffs along the western shore of the Chesapeake Bay. The strata, subdivided into 21 numbered beds, have been shown by borehole transects to be the landward fringe of regional Mid-Atlantic margin successions (Browning et al., Bull. GSA, 2006). The latter find a quasi-cyclic stack of sequences from 24 to 10 Ma, averaging 1.27 Ma per sequence (Cape May)-probably glacioeustatic responses to ca. 1.2 Ma modulation of the 41 ka obliquity cycle. We posit that the two most pronounced global climate events during the 20-10 Ma interval recorded in the Calvert Cliffs strata are uniquely recognizable as sea level-related features. These events are the Middle Miocene Climatic Optimum (MMCO; peaking ca. 15.7-15.5 Ma) and the Antarctic Ice Sheet Expansion (AISE; ca.13.9 Ma). We use these dates to recalibrate the ages of upper Calvert Formation beds 11-14. Miocene warmth peaked during the anomalous MMCO, with ice-free areas along the Antarctic coast. The locally unique "Parkers Creek Bone Bed" (Bed 12) may record this event because its marine fauna show the deepest shelf waters of the ca. 20-10 Ma Calvert Cliffs exposures (Kidwell, J. Sed. Res., 1997). Terrestrial vertebrate remains introduced from adjacent lands also indicate subtropical climates. The temporal correlation between the MMCO and peak eruption rates of the Columbia River Flood Basalts suggests the MMCO was at least partly caused by increased volcanogenic CO (sub 2) from those voluminous, volatile-rich eruptions. The following AISE occurred ca. 13.9 Ma, and we associate this cooling, which lowered eustatic sea levels by ca. 40 m, with the only known buried channel within in the Calvert Cliffs strata-the Kenwood Beach Channel, filled by sand by Bed 17 time, is 5-7 m deep and 3 km wide in exposure. We thereby interpolate ages of ca. 15.5-14.5 Ma for Bed 13 and 14.5-14.4 Ma for Bed 14. While within the range of earlier age estimates, our assignments are up to ca. 1.5 Ma older than Sr (super 86) /Sr (super 87) ages reported for mollusk shells (Browning et al., 2006), a discrepancy we attribute to shell alteration. Our ages imply that lithic erratics (previously described from beds 12-14) were deposited during warm climates, strengthening the case for transport by driftwood, not ice.

Forty-two specimens were collected from mass mortality and appendage-rich surfaces, in association with other crustaceans including modern cumaceans and shrimps. The exceptional degree of preservation of the new taxon has permit the description of complete dorsal and ventral features, claws, all walking legs, sexually dimorphic abdomen, pleopods, mouthparts, and large compound eyes, allowing comparison with fossil and extant decapods. A brachyuran affinity is supported by the possession of a symmetric abdomen lacking uropods and articulated rings, short antennae and antennulae that are located between the eyes, possession of only one pair of chelae, therefore pereiopods or walking legs achelate, and last pereiopod visible. In addition, kinship with ancient members within the Subsection Raninoida is suggested by the dorsally exposed first abdominal somites, fusiform carapace, bifid rostrum, spanner-like chelipeds with fixed finger deflected approximately 90 degrees , paddle-like achelate pereiopods, non-prehensile fifth pair of legs carried subdorsally, and apparent absence of thoracic sexual openings. However, its particular bauplan (e.g., dorsal characters and unique sternal configuration) is matchless among any known fossil or extant brachyuran crabs, meriting the erection of the new superfamily. The functional morphology of carapace, mouthparts and limbs of this taxon suggests an agile marine burrower and swimmer, well suited for predatory/scavenging purposes. This new taxon provides valuable information on the macroevolutionary patterns among ancient crabs, and enhances our understanding on the role of the Neotropics on the origin and diversification of brachyuran lineages during Cretaceous times.

We conducted a geospatial analysis using existing data to better inform future surveillance efforts. Using active surveillance data collected between 2005 and 2007, we identified locations in Sankuru district, Democratic Republic of Congo (DRC) where there have been one or more cases of human monkeypox. To assess what taxa constitute the main reservoirs of monkeypox, we tested whether human cases were associated with (i) rope squirrels (Funisciurus sp.), which were implicated in monkeypox outbreaks elsewhere in the DRC in the 1980s, or (ii) terrestrial rodents in the genera Cricetomys and Graphiurus, which are believed to be monkeypox reservoirs in West Africa. Results suggest that the best predictors of human monkeypox cases are proximity to dense forests and associated habitat preferred by rope squirrels. The risk of contracting monkeypox is significantly greater near sites predicted to be habitable for squirrels (OR = 1.32; 95% CI 1.08-1.63). We recommend that semi-deciduous rainforests with oil-palm, the rope squirrel's main food source, be prioritized for monitoring.

In this review paper, we evaluate the fundamental controls on the origin of these phenomena, investigate the taphonomic biases that influence their composition, and summarize their palaeoecological significance. Following earlier workers, we highlight that high rates of burial and accommodation are essential for the formation and preservation of T (super 0) assemblages. Contexts especially favourable for their origin include ashfalls proximal to volcanic centres, coastal plains drowned by relative sea-level rise, and fluvial environments such as channel bars, crevasse splays, and distributary lobes. Long-term preservation requires high rates of subsidence. Consequently, the vast majority of Palaeozoic T (super 0) assemblages are confined to wetland settings at, or close to, sea level, whereas drylands are poorly represented and uplands rarely sampled, if ever. However, this is not the only major bias in the fossil record; taphonomic processes selectively preserve plants dependent on their anatomy and stature, and on groundwater chemistry. Thus, although T (super 0) assemblages offer unrivalled insights into the nature of ancient forests (whole-plant reconstructions, tree density, canopy height, productivity, plant hydraulics, cohort dynamics, spatial heterogeneity, ecological gradients, tree-sediment interactions, and animal-plant interactions, to name but a few), it is naive to believe they provide 'photographic snapshots' of palaeoecosystems. None the less, careful taphonomic analysis of T (super 0) assemblages offers the potential for a nuanced understanding of these evocative phenomena, and much remains to be learned from these important palaeoecological resources.

Ongoing oil exploration in the region focuses on complex structural areas and non-conventional reservoirs. In MMVB Petroleum System, the Umir formation is a highly effective regional seal, especially for structural traps involving reverse faults and Cenozoic reservoirs. The upper Umir sandstones have recently been considered as a reservoir in the Central Eastern Basin. But because of both large structural complexities and the presence of a major unconformity known as the Middle Magdalena Valley Unconformity (MMVU), the regional distribution of these oil-bearing sandstones is not well-known, and exploratory risk is high. This research focuses on developing a biostratigraphic framework for the Late Cretaceous Umir Formation using palynology. Major biostratigraphic events will be used to develop regional correlations, and serve as a key tool for on-site, real-time biostratigraphic control of exploratory wells. The Umir formation is composed of a series of dark grey to black shales, siltstones and coal beds, with cross stratified sandstones and intraformational conglomerates in the upper section. The depositional environment was a bay or extensive coastal plain. The study area is located on the western side of the Los Andes syncline, in Central Eastern MMVB. Eighty-two samples were selected from four cores, and are being analyzed for palynological content. The palynological samples were processed in the biostratigraphy Laboratory of the Colombian Petroleum Institute (ICP). Standard palynological analyses are being conducted at Louisiana State University (LSU) using a BX41 Olympus light microscope under a 60X oil immersion objective. A minimum of 300 grains is tabulated per slide. Thus far, some of the key Maastrichtian terrestrial palynomorphs recovered include Echimonocolpites protofranciscoi, Proteacidites dehaani, Buttinia andreevi, Echitriporites trianguliformis, Echitriporites suescae, Bacumorphomonocolpites taussae, and Monocolpites grandispiniger. Two layers with a marked marine influence have been recorded as well. The excellent recovery of abundant and diverse species shows potential to find new markers and events to improve the Maastrichtian biostratigraphy of Northern South America.

The emphasis of the work described here is an assessment of the overall accuracy of our survey results, which are based on a semi-empirical generalized model of asteroid thermal emission. The NASA Spitzer Space Telescope has been operated in the so-called Warm Spitzer mission phase since the cryogen was depleted in 2009 May, with the two shortest-wavelength channels, centered at 3.6 mu m and 4.5 mu m, of the Infrared Array Camera continuing to provide valuable data. The set of some 170 NEOs in our current Warm Spitzer results catalog contains 28 for which published taxonomic classifications are available, and 14 for which relatively reliable published diameters and albedos are available. A comparison of the Warm Spitzer results with previously published results ("ground truth"), complemented by a Monte Carlo error analysis, indicates that the rms Warm Spitzer diameter and albedo errors are + or -20% and + or -50%, respectively. Cases in which agreement with results from the literature is worse than expected are highlighted and discussed; these include the potential spacecraft target 138911 2001 AE (sub 2) . We confirm that 1.4 appears to be an appropriate overall default value for the relative reflectance between the V band and the Warm Spitzer wavelengths, for use in correction of the Warm Spitzer fluxes for reflected solar radiation.

As a result of this arc-arc collision, parts of the submarine Izu-Bonin upper crustal sequences have been accreted and uplifted to form the Izu Peninsula, exposing seafloor volcaniclastic deposits, associated lava flows, and coeval intrusive bodies. Parts of this sequence have been subjected to extensive hydrothermal alteration, and these altered rocks have previously been interpreted as representative of hypothetical widespread Middle Miocene basement that presumably underlay northern Izu-Bonin arc volcanoes. New zircon U-Pb ages presented here, however, show that both fresh and altered volcanic sequences exposed in Izu Peninsula are broadly contemporaneous and were products of the same Late Miocene to Pleistocene magmatism. Geochemical characteristics of these sequences show them to have formed in the Izu-Bonin rear-arc environment, providing an unusual opportunity to investigate in detail the growth and architecture of a rear-arc region in an active intra-oceanic arc. Moreover, zircon ages from altered basal units of Kozushima and Niijima, Quaternary volcanic islands in the northern Izu-Bonin rear-arc, show that these islands rest on units only slightly older (<1 Ma) than the main body of these subaerial edifices, not, as previously believed, part of a regional older Miocene basement. The near-continuum growth of these arc volcanoes and their underlying successions, plus the absence of a distinctly older basement underlying the Izu Peninsula and northern Izu-Bonin arc, provide new insight into upper crust development in an intra-oceanic, convergent margin environment.

Vallis Schroeteri, located on the Aristarchus Plateau, is the largest rille on the Moon, and it displays three key morphologic components: the Cobra Head, the 155-km-long primary rille, and the 240-km-long inner rille. Observations of terrestrial eruptions are applied here to help explain the morphologic relationships observed for Vallis Schroeteri. The Cobra Head, a 10-km-wide source vent surrounded by a 35-km-diameter and 900-m-high low shield, might have been constructed from flows, spatter, and pyroclastic deposits erupted during lava fountain events, similar to the early stages of the vent at Pu"u 'O'o in Hawaii and the final morphology of Bandera Crater, a cinder cone in New Mexico. The vent fed an initial sheet flow controlled by pre-eruption topography. A channel formed within this sheet flow was the foundation for the primary rille, which deepened through construction and thermomechanical erosion by lava. The inner rille is confined to the flat floor of the primary rille and is characterized by tight gooseneck meanders. This rille crosscuts the distal scarp of the primary rille and extends toward Oceanus Procellarum. This enigmatic relationship can be explained through backup, overflow, and diversion of the lava into a new rille that eroded into the margin of the primary rille. Similar backup, overflow, and redirection of the lava flow were observed during the 1984 Mauna Loa eruption in Hawaii. Analysis of the final morphology of lunar rilles provides key information about lunar volcanic processes and insight into the local stratigraphy.

Samples were analyzed using Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) yielding for the first time continuous individual trace elemental records of up to 69 years in length. The resulting algal Mg/Ca, Sr/Ca, U/Ca, and Ba/Ca ratios are reproducible within individual sample specimens. Algal Mg/Ca ratios were additionally validated by electron microprobe analyses (Amchitka sample). Algal Sr/Ca, U/Ca, and Ba/Ca ratios were compared to algal Mg/Ca ratios, which previously have been shown to reliably record sea surface temperature (SST). Ratios of Sr/Ca from both Clathromorphum species show a strong positive correlation to temperature-dependent Mg/Ca ratios, implying that seawater temperature plays an important role in the incorporation of Sr into algal calcite. Linear Sr/Ca-SST regressions have provided positive, but weaker relationships as compared to Mg/Ca-SST relationships. Both, algal Mg/Ca and Sr/Ca display clear seasonal cycles. Inverse correlations were found between algal Mg/Ca and U/Ca, Ba/Ca, and correlations to SST are weaker than between Mg/Ca, Sr/Ca and SST. This suggests that the incorporation of U and Ba is influenced by other factors aside from temperature.

Encrusting coralline algae, which deposit annual growth increments in a high Mg-calcite skeleton, are amongst the longest-lived shallow marine organisms. In fact, a live-collected plant has recently been shown to have lived for at least 850 years based on radiometric dating. While a number of investigations have successfully used geochemical information of coralline algal skeletons to reconstruct sea surface temperatures, less attention has been paid to employ growth increment widths as a temperature proxy. Here we explore the relationship between growth and environmental parameters in Clathromorphum compactum collected in the subarctic Northwestern Atlantic. Results indicate that growth-increment widths of individual plants are poorly correlated with instrumental sea surface temperatures (SST). However, an averaged record of multiple growth increment-width time series from a regional network of C. compactum specimens up to 800 km apart reveals strong correlations with annual instrumental SST since 1950. Hence, similar to methods applied in dendrochronology, averaging of multiple sclerochronological records of coralline algae provides accurate climate information. A 115-year growth-increment width master chronology created from modern-collected and museum specimens is highly correlated to multidecadal variability seen in North Atlantic sea surface temperatures. Positive changes in algal growth anomalies record the well-documented regime shift and warming in the northwestern Atlantic during the 1990s. Large positive changes in algal growth anomalies were also present in the 1920s and 1930s, indicating that the impact of a concurrent large-scale regime shift throughout the North Atlantic was more strongly felt in the subarctic Northwestern Atlantic than previously thought, and may have even exceeded the 1990s event with respect to the magnitude of the warming.

SRI practices increased yield by 47% on average and showed potential to increase yield by over 90%, while reducing water consumption by as much as 86%. SRI yields were correlated with available soil K and the difference between SRI and the conventional system yields was positively correlated with extractable Ca, Mg and Mn. The results of this study indicate that SRI is a promising rice production system for smallholder farmers in rural Panama farming under Panamanian soil conditions.

The Paleocoastal sites, dated between approximately 12,200 and 11,200 years ago, contain numerous stemmed projectile points and crescents associated with a variety of marine and aquatic faunal remains. At site CA-SRI-512 on Santa Rosa Island, Paleocoastal peoples used such tools to capture geese, cormorants, and other birds, along with marine mammals and finfish. At Cardwell Bluffs on San Miguel Island, Paleocoastal peoples collected local chert cobbles, worked them into bifaces and projectile points, and discarded thousands of marine shells. With bifacial technologies similar to those seen in Western Pluvial Lakes Tradition assemblages of western North America, the sites provide evidence for seafaring and island colonization by Paleoindians with a diversified maritime economy.

Location Western North America (California to Alaska, excluding Mexico). Methods We undertook extensive analysis of literature and collections records to characterize the invasion history of non-native species (invertebrates, microalgae and microorganisms) with established populations in coastal marine (tidal) waters of western North America through 2006. Using these data, we estimated (1) the proportion of first regional records of non-native species that occurred in California and (2) the relative contribution of transfer mechanisms to California invasions (or vector strength) over time. Results Excluding vascular plants and vertebrates, we identified 290 non-native marine species with established populations in western North America, and 79% had first regional records from California. Many (40-64%) of the non-native species in adjacent states and provinces were first reported in California, suggesting northward spread. California also drives the increasing regional rate of detected invasions. Of 257 non-native species established in California, 59% had first regional records in San Francisco Bay; 57% are known from multiple estuaries, suggesting secondary spread; and a majority were attributed to vessels (ballast water or hull fouling) or oysters, in some combination, but their relative contributions are not clear. For California, more than one vector was possible for 56% of species, and the potential contribution of ballast water, hull fouling and live trade increased over time, unlike other vectors. Main conclusions California, especially San Francisco Bay, plays a pivotal role for marine invasion dynamics for western North America, providing an entry point from which many species spread. This pattern is associated historically with high propagule supply and salinity. Any effective strategies to minimize new invasions throughout this region must (1) focus attention on California and (2) address current uncertainty and future shifts in vector strength.

However, identifying the mechanisms behind these influences is complicated by the many potential pathways (often indirect) between land use and ecosystems and by the long-lasting effects of past land use. To support ecosystem restoration and conservation efforts, we need to better understand these indirect and lasting effects. 2.We constructed structural equation models (SEM) to evaluate the direct and indirect effects of contemporary (2002) land use (agriculture and development) and change in land use from 1952 to 2002 on present-day streams (n=190) in Maryland, U.S.A. Additional variables examined included site location, system size, altitude, per cent sand in soils, riparian condition, habitat quality, stream water NO3-N and benthic macroinvertebrate and fish measures of stream condition. Our first SEM (2002 Land Use) included the proportions of contemporary agriculture and development in catchments in the model. The second SEM (Land Use Change) included five measures of land use change (proportion agricultural in both times, developed in both times, agricultural in 1952 and developed in 2002, forested in 1952 and developed in 2002 and agricultural in 1952 and forested in 2002). 3.The data set fit both SEMs well. The 2002 Land Use model explained 71% of variation in NO3-N and 55%, 42% and 38% of variation in riffle quality, macroinvertebrate condition and fish condition, respectively. The Land Use Change model explained similar amounts of variation in NO3-N (R2=0.72), riffle quality (R2=0.57) and macroinvertebrate condition (R2=0.44) but slightly more variation in fish condition (R2=0.43). 4.Both models identified pathways through which landscape variables affect stream responses, including negative direct effects of latitude on macroinvertebrate and fish conditions and positive direct and indirect effects of altitude on NO3-N, riffle quality and macroinvertebrate and fish conditions. The 2002 Land Use model showed contemporary development and agriculture had positive total effects on NO3-N (both through direct pathways); contemporary development had negative effects on macroinvertebrate condition. The Land Use Change model showed that contemporary developed land that was forested in 1952 had no effects on NO3-N; current developed land that was developed or agricultural in 1952 showed positive effects on NO3-N. Forests that were agricultural in 1952 had negative effects on NO3-N, suggesting reduced NO3-N export with reforestation. The Land Use Change model also showed negative total effects of all types of contemporary developed land (developed, agricultural or forested in 1952) on benthic condition. Developed land that was forested in 1952 had negative effects on fish condition. Forest sites that were agricultural in 1952 had negative effects on fish and macroinvertebrate conditions, suggesting a long-term imprint of abandoned agriculture in stream communities. 5.Our analyses (i) identified multiple indirect effects of contemporary land use on streams, (ii) showed that current land uses with different land use histories can exhibit different effects on streams and (iii) demonstrated an imprint of land use lasting >50years. Knowledge of these indirect and long-term effects of land use will help to conserve and restore streams.

Such a gap was previously proposed to explain an abrupt change in megafloral assemblages in the northern Appalachian Basin and by extension across all of North America. Conodont-based correlation from the essentially complete low-shelf Midcontinent succession (distal from the highstand shoreline), through the mid-shelf Illinois Basin, to the high shelf of the Appalachian Basin (proximal to highstand shoreline) demonstrates that all major approximately 400 kyr cyclothem groupings in the Midcontinent are recognizable in the Illinois Basin. In the Appalachian Basin, however, the grouping at the base of the Missourian is represented only by paleosols and localized coal. The immediately preceding grouping was removed very locally by paleovalley incision, as is evident at the 7-11 Mine, Columbiana County, Ohio, from which the original megafloral data were derived. At the few localities where incised paleodrainage exists, there may be a gap of approximately 1000 kyr, but a gap of no more than approximately 600 kyr occurs elsewhere in the Appalachian Basin at that level and its magnitude progressively decreases westward into the Illinois ( approximately 300 kyr) and Midcontinent (<200 kyr) Basins. Thus, while a gap is present near the Desmoinesian-Missourian boundary in North America, it is typically more than an order of magnitude smaller than that originally proposed and is similar to the gaps inferred at sequence boundaries between cyclothems at many horizons in the Pennsylvanian of North America.

Methods: We characterized variation in species richness among islands and whole archipelagoes by analyzing species-area relationships (SARs). By partitioning each flora into putative phylogenetic lineages each derived from a given colonization event, we explored several ways in which speciation contributes to SARs. Key results: Specifically, these groups exhibit expected island SARs and a whole archipelago SAR characterized by a steep slope. The number of species added by net cladogenesis increases with area much more quickly than the number contributed by net colonization from outside. In each of the three archipelagoes, most colonists do not speciate, while many species occur in a few diverse colonist lineages. Colonization events that are unique to a given archipelago are in more prone to speciation than lineages with close relatives in the other archipelagoes. Most lineages with relatives in all three archipelagoes have one species in each, suggesting a similar tendency not to diversify. On the other hand, a correlation between lineage size in one archipelago and that of related lineages in other archipelagoes suggests a consistent tendency among diverse groups to speciate extensively. Lineages with multiple species in each archipelago also tend to have far more species in the largest archipelago, the Hawaiian Islands. Conclusions: The most diverse lineages exhibit a strong response to archipelago area. These diverse, area-sensitive lineages contribute substantially to the slope of the inter-archipelago SAR. Regional species pools elsewhere may exhibit similar steep-sloped SARs; thus, these findings may inform how the behavior of lineages with different responses to increasing shapes these patterns.

The mission reached a milestone toward meeting that goal: the discovery of its first rocky planet, Kepler-10b. Two distinct sets of transit events were detected: (1) a 152+ or -4 ppm dimming lasting 1.811+ or -0.024 hr with ephemeris T[BJD]=2454964.57375 (super +0.00060) (sub -0.00082) + N (super *) 0.837495 (super +0.000004) (sub -0.000005) days and (2) a 376+ or -9 ppm dimming lasting 6.86+ or -0.07 hr with ephemeris T[BJD]=2454971.6761 (super +0.0020) (sub -0.0023) +N (super *) 45.29485 (super +0.00065) (sub -0.0007 6) days. Statistical tests on the photometric and pixel flux time series established the viability of the planet candidates triggering ground-based follow-up observations. Forty precision Doppler measurements were used to confirm that the short-period transit event is due to a planetary companion. The parent star is bright enough for asteroseismic analysis. Photometry was collected at 1 minute cadence for >4 months from which we detected 19 distinct pulsation frequencies. Modeling the frequencies resulted in precise knowledge of the fundamental stellar properties. Kepler-10 is a relatively old (11.9+ or -4.5 Gyr) but otherwise Sun-like main-sequence star with T (sub eff) =5627+ or -44 K, M (sub *) =0.895+ or -0.060 M (sub []) , and R (sub *) =1.056+ or -0.021 R (sub []) . Physical models simultaneously fit to the transit light curves and the precision Doppler measurements yielded tight constraints on the properties of Kepler-10b that speak to its rocky composition: M (sub P) =4.56 (super +1.17) (sub -1.29) M (sub Earth) , R (sub P) =1.416 (super +0.033) (sub -0.036) R (sub Earth) , and rho (sub P) =8.8 (super +2.1) (sub -2.9) g cm (super -3) . Kepler-10b is the smallest transiting exoplanet discovered to date. Copyright (Copyright) 2011. The American Astronomical Society. All rights reserved.

For the next seven years, we surveyed the elevation annually, measured sand thickness, and collected samples for lithologic and foraminiferal analysis across an overwash fan that extended to the back-barrier Pamlico Sound. The first significant environmental change occurred between 2004-2005 when 35% of the unvegetated overwash sand was removed, presumably by deflation, mostly from the ocean side of the transect. From 2005-2008 the overwash deposit remained virtually unchanged and the surface continued to be barren of marsh plants and foraminifera. In 2008-2009, the marsh grass Spartina patens began to populate the surface in small, isolated patches. Typical agglutinated salt marsh foraminifera were still absent. However, samples at the highest elevations of the transect contained abundant live specimens of Trichohyalus aguayoi, a calcareous taxon not previously recorded north of the Caribbean. In 2009-2010, verified tide data reveal 30 instances when wind-generated tides sustained elevations 0.3 m above mean higher high water (four times more frequently than any of the previous years). Much of the remaining overwash sand was removed, predominantly from the sound side of the transect. Only 20% of the original overwash deposit now remains, mostly on the oceanside of the transect. The sound side is now below the elevation of mean higher high water and the surface is covered by the marsh grass Spartina alterniflora. Live foraminifera are abundant, the assemblage is completely agglutinated, and dominated by the salt marsh taxa Arenoparrella mexicana and Trochammina inflata. The average elevation of the undeflated portion of the overwash deposit is still approximately 0.15 m above the tidal frame. Although now entirely covered by Spartina patens, marsh foraminifera have not yet repopulated this part of the fan. The calcareous species Trichohyalus aguayoi is still abundant. We do not expect salt marsh foraminifera to recolonize this part of the overwash fan until its elevation is reduced to ca. mean higher high water - unlikely in the near term due to the dense vegetation.

Deposits from Hurricanes Ivan, Katrina, and Rita have been identified in cores from the Mississippi delta shelf using radionuclide analysis (7Be, 234Th, and 210Pb) coupled with X-radiography. By comparing foraminiferal assemblages contained within these known hurricane deposits with those of non-storm deposits in these cores and in post-hurricane surface samples from the offshore Mississippi delta, it is hoped to gain a better understanding of how hurricanes transport sediments in a neritic deltaic environment. Box- and multi-cores as well as ponar surface grab samples were collected in a series of cruises off the Mississippi Delta in 2004, 2005, and 2007, reoccupying some stations twice or all three years. Eight cores from three revisited stations and five surface grab samples were selected in a transect trending southwest from Southwest Pass from ca. 20 m water depth to the head of the Mississippi Canyon at 170 m water depth. Two 20 mL foraminiferal subsamples were taken from each hurricane deposit in each core, as well as two samples from the pre-storm deposits and two from post-storm sediments, where available. Identification of foraminifera was confirmed via comparison with type specimen lodged in collections of the Smithsonian Institution. ANOVAs performed on percentages of common species in several cores indicate that there is a statistically significant difference in foraminiferal assemblages between storm and non-storm deposits. Storm beds analyzed generally contained fewer foraminifera in 20 mL than non-storm units and were dominated by Textularia earlandi and often Bolivina lowmani, whereas non-storm units were dominated by Epistominella vitrea and Buliminella morgani. Further analyses will investigate foraminiferal distribution data and the provenance of individual storm beds.

However, recent studies have hypothesized that vertebrate microfossil bonebeds (VMBs) accumulate in small lacustrine environments and are only later reworked by higher-energy fluvial systems. If this is the case, one would expect to see specific taphonomic and paleoecological differences: fluvially deposited VMBs should exhibit poorer preservation and more size winnowing than those deposited in lacustrine environments. Smaller taxa may be present in lacustrine VMBs, but absent in fluvial ones due to this size-winnowing. This study investigates the relationship between the taphonomy of microvertebrate fossils and their depositional environment using assemblages preserved at multiple VMBs from the Hell Creek Formation in central Montana. We collected 20 kg bulk samples from five fluvial and lacustrine VMBs identified in the Late Cretaceous Hell Creek Formation in Garfield County, MT. After screening, identifying, and sorting the samples, we measured taphonomic characteristics of the fossils, such as wear, size, and shape. The taphonomic data were statistically analyzed to see whether preservation differed significantly according to paleoenvironment. Additionally, we quantified and compared species abundance, richness, and evenness among VMBs to assess paleoecological differences between sites deposited in lacustrine versus fluvial environments. Preliminary results from all sites indicate a high abundance of osteichthyans (particularly representatives of Lepisosteidae) with successively rarer occurrences of reptiles, amphibians, and mammals. The majority of the fossils possess aquatic or semiaquatic affinities. Lastly, the samples derived from lacustrine deposits appear to have greater species richness than those samples from fluvial deposits. Together these data provide support for a common depositional source across multiple sites.

Behaviors and activity patterns of 12 (5.7) animals were recorded over a 1-year period. During that time, fecal samples were collected 2-7 times/week from 16 (7.9) individuals (six of these were included in the behavioral study) for the analysis of testosterone, progesterone and estrogen metabolite concentrations. Activity pattern and excretion of gonadal steroids followed a seasonal pattern. Specifically, dogs were cathemeral in summer, and primarily nocturnal in winter. In the males, testosterone concentrations were at baseline from April through September, began to rise in October and reached peak concentrations in February (P<0.05). In the females, elevated estrogen (P<0.05) was observed in March followed by an increase in progestagen concentrations from March through May (P<0.05) in both pregnant and pseudopregnant animals. Gender significantly influenced monthly testosterone/estrogen ratio (P<0.01); values were higher in males than in females throughout the year with overall percentage of overlapping values between males and females being 28%. In summary, this study characterized cirannual fluctuations in behaviors and gonadal steroid metabolites in the raccoon dog maintained in captivity. Because there is no obvious sexual dimorphism, the differences in testosterone/estrogen ratio may be useful for gender differentiation (72% accuracy), especially among individuals living in the wild.

This death-grip behaviour functions to place insects in an ideal location for spore dispersal from a dead body following host death. Fossil leaves record many aspects of insect behaviour (feeding, galls, leaf mining) but to date there are no known examples of behavioural manipulation. Here, we document, to our knowledge, the first example of the stereotypical death grip from 48 Ma leaves of Messel, Germany, indicating the antiquity of this behaviour. As well as probably being the first example of behavioural manipulation in the fossil record, these data support a biogeographical parallelism between mid Eocene northern Europe and recent southeast Asia.

The host star has a mass of 0.82+ or -0.03 M (sub []) , radius of 0.79 (super +0.10) (sub -0.04) R (sub []) , effective temperature 5079+ or -88 K, and metallicity [Fe/H] = -0.04+ or -0.08. The planetary companion has a mass of 0.059+ or -0.007 M (sub J) , and radius of 0.565 (super +0.072) (sub -0.032) R (sub J) yielding a mean density of 0.40+ or -0.10 g cm (super -3) . HAT-P-26b is the fourth Neptune-mass transiting planet discovered to date. It has a mass that is comparable to those of Neptune and Uranus, and slightly smaller than those of the other transiting Super-Neptunes, but a radius that is approximately 65% larger than those of Neptune and Uranus, and also larger than those of the other transiting Super-Neptunes. HAT-P-26b is consistent with theoretical models of an irradiated Neptune-mass planet with a 10 M (sub Earth) heavy element core that comprises > or =50% of its mass with the remainder contained in a significant hydrogen-helium envelope, though the exact composition is uncertain as there are significant differences between various theoretical models at the Neptune-mass regime. The equatorial declination of the star makes it easily accessible to both Northern and Southern ground-based facilities for follow-up observations. Copyright (Copyright) 2011.

Multiple planets transiting the same star reveal much more: period ratios determine stability and dynamics, mutual gravitational interactions reflect planet masses and orbital shapes, and the fraction of transiting planets observed as multiples has implications for the planarity of planetary systems. But few stars have more than one known transiting planet, and none has more than three. Here we report Kepler spacecraft observations of a single Sun-like star, which we call Kepler-11, that reveal six transiting planets, five with orbital periods between 10 and 47days and a sixth planet with a longer period. The five inner planets are among the smallest for which mass and size have both been measured, and these measurements imply substantial envelopes of light gases. The degree of coplanarity and proximity of the planetary orbits imply energy dissipation near the end of planet formation.

We have studied the age, composition and provenance of granitoids and sandstones of the Santa Marta Massif and Rancheria Basin, northern Colombia, to relate deep-seated and surface tectonic processes attending the Late Cretaceous-Palaeogene history of the northern Andes. Our results indicate the development of five tectonic episodes: (1) collision of northwestern South America with a 92-80 Ma Caribbean arc (70 Ma); (2) late-collisional to early-subduction metamorphism and magmatism (65 Ma); (3) distal accumulation of a thick siliciclastic sequence (60-58 Ma); (4) renewed arc magmatism (58-50 Ma); and (5) magmatic quiescence and block uplift (post-50 Ma). The first episodes are related to the onset of subduction, and the last episode is related to shallow subduction and oblique convergence. Similar events in Colombia and Ecuador reveal that the Late Cretaceous-Eocene orogeny of the northern Andes was influenced by the collision and subduction of the Caribbean oceanic plate.

However, there is increasing evidence that diversity patterns observed directly from the fossil record are strongly influenced by fluctuations in the quality of our sampling of the rock record; thus, any patterns we see may reflect sampling biases, rather than genuine biological signals. Previous dinosaur diversity studies have suggested that fluctuations in sauropodomorph palaeobiodiversity reflect genuine biological signals, in comparison to theropods and ornithischians whose diversity seems to be largely controlled by the rock record. Most previous diversity analyses that have attempted to take into account the effects of sampling biases have used only a single method or proxy: here we use a number of techniques in order to elucidate diversity. A global database of all known sauropodomorph body fossil occurrences (2024) was constructed. A taxic diversity curve for all valid sauropodomorph genera was extracted from this database and compared statistically with several sampling proxies (rock outcrop area and dinosaur-bearing formations and collections), each of which captures a different aspect of fossil record sampling. Phylogenetic diversity estimates, residuals and sample-based rarefaction (including the first attempt to capture 'cryptic' diversity in dinosaurs) were implemented to investigate further the effects of sampling. After 'removal' of biases, sauropodomorph diversity appears to be genuinely high in the Norian, Pliensbachian-Toarcian, Bathonian-Callovian and Kimmeridgian-Tithonian (with a small peak in the Aptian), whereas low diversity levels are recorded for the Oxfordian and Berriasian-Barremian, with the Jurassic/Cretaceous boundary seemingly representing a real diversity trough. Observed diversity in the remaining Triassic-Jurassic stages appears to be largely driven by sampling effort. Late Cretaceous diversity is difficult to elucidate and it is possible that this interval remains relatively under-sampled. Despite its distortion by sampling biases, much of sauropodomorph palaeobiodiversity can be interpreted as a reflection of genuine biological signals, and fluctuations in sea level may account for some of these diversity patterns.

For terrestrial social animals, predation, feeding success, and social competition are thought to be three of the most important variables. The relative importance of these three factors was investigated in groups of ring-tailed coatis (Nasua nasua) in Iguazu, Argentina. Different age/sex classes responded differently to these three variables. Coatis were found in close proximity to their own age/sex class more often than random, and three out of four age/sex classes were found to exhibit within-group spatial position preferences which differed from random. Juveniles were located more often at the front edge and were rarely found at the back of the group. Juveniles appeared to choose spatial locations based on feeding success and not predation avoidance. Since juveniles are the most susceptible to predation and presumably have less prior knowledge of food source location, these results have important implications in relation to predator-sensitive foraging and models of democratic group leadership. Subadults were subordinate to adult females, and their relationships were characterized by high levels of aggression. This aggression was especially common during the first half of the coati year (Nov-April), and subadults were more peripheralized during this time period. Subadults likely chose spatial positions to avoid aggression and were actively excluded from the center of the group by adult females. In the Iguazu coati groups, it appeared that food acquisition and social agonism were the major determinants driving spatial choice, while predation played little or no role. This paper demonstrates that within-group spatial structure can be a complex process shaped by differences in body size and nutritional requirements, food patch size and depletion rate, and social dominance status.

In this study, we test the hypothesis that medial cuneiform morphology falls on a morphocline in gorillas that tracks function related to hallucial abduction ability and relative frequency of arboreality. This morphocline predicts that western gorillas, being the most arboreal, should display a medial cuneiform anatomy that reflects the greatest hallucial abduction ability, followed by grauer gorillas, and then by mountain gorillas. Using a three-dimensional methodology to measure angles between articular surfaces, relative articular and nonarticular areas, and the curvatures of the hallucial articular surface, the functional predictions are partially confirmed in separating western gorillas from both eastern gorillas. Western gorillas are characterized by a more medially oriented, proportionately larger, and more mediolaterally curved hallucial facet than are eastern gorillas. These characteristics follow the predictions for a more prehensile hallux in western gorillas relative to a more stable, plantigrade hallux in eastern gorillas. The characteristics that distinguish eastern gorilla taxa from one another appear unrelated to hallucial abduction ability or frequency of arboreality. In total, this reexamination of medial cuneiform morphology suggests differentiation between eastern and western gorillas due to a longstanding ecological divergence and more recent and possibly non-adaptive differences between eastern taxa.

A mechanistic understanding of how plant traits influence microbial processes is needed in order to predict the ecosystem-level effects of natural or anthropogenic change. This is particularly true in wetland ecosystems, where plants alter the availability of both electron donors (e.g., organic carbon) and electron acceptors (e.g., oxygen and ferric iron), thereby regulating the total amount of anaerobic respiration and the production of methane, a highly potent greenhouse gas. In this study, we examined how plant traits associated with plant inputs of carbon (photosynthesis and biomass) and oxygen (root porosity and ferric iron on roots) to mineral soils relate to microbial competition for organic carbon and, ultimately, methane production. Plant productivity was positively correlated with microbial respiration and negatively correlated to methane production. Root porosity was relatively constant across plant species, but belowground biomass, total biomass, and the concentration of oxidized (ferric) iron on roots varied significantly between species. As a result the size of the total root oxidized iron pool varied considerably across plant species, scaling with plant productivity. Large pools of oxidized iron were related to high CO sub(2):CH sub(4) ratios during microbial respiration, indicating that as plant productivity and biomass increased, microbes used non-methanogenic respiration pathways, most likely including the reduction of iron oxides. Taken together these results suggest that increased oxygen input from plants with greater biomass can offset any potential stimulation of methanogenic microbes from additional carbon inputs. Because the species composition of plant communities influences both electron donor and acceptor availability in wetland soils, changes in plant species as a consequence of anthropogenic disturbance have the potential to trigger profound effects on microbial processes, including changes in anaerobic decomposition rates and the proportion of mineralized carbon emitted as the greenhouse gas methane.

These techniques are able to identify cycles superimposed on the long-term trends of the Phanerozoic. We review prior results and analyze data previously reduced and published. Joint time-series analysis of various reductions of the Sepkoski Data, Paleobiology Database, and Fossil Record 2 indicate the same periodicity in biodiversity of marine animals at 62 Myr. We have not found this periodicity in the terrestrial fossil record. We have found that the signal strength decreases with time because of the accumulation of apparently "resistant" long-lived genera. The existence of a 62-Myr periodicity despite very different treatment of systematic error, particularly sampling-strength biases, in all three major databases strongly argues for its reality in the fossil record.

How interactions between phylogeny and ecology affect patterns of extinction AN - 840344409; 2011-012761 AB - Extinctions are caused by environmental and ecological change but are recognized and measured in the fossil record by the disappearance of clades or lineages. If the ecological preferences of lineages or taxa are weakly congruent with their phylogenetic relationships, even large ecological perturbations are unlikely to drive major clades extinct because the factors that eliminate some species are unlikely to affect close relatives with different ecological preferences. In contrast, if phylogenetic relatedness and ecological preferences are congruent, then ecological perturbations can more easily cause extinctions of large clades. In order to quantify this effect, we used a computer model to simulate the diversification and extinction of clades based on ecological criteria. By varying the parameters of the model, we explored (1) the relationship between the extinction probability for a clade of a given size (number of terminals) and the overall intensity of extinction (the proportion of the terminals that go extinct), and (2) the congruence between ecological traits of the terminals and their phylogenetic relationships. Data from two extinctions (planktonic foraminifera at the Eocene/Oligocene boundary and vascular land plants at the Middle/Late Pennsylvanian boundary) show phylogenetic clustering of both ecological traits and extinction probability and demonstrate the interaction of these factors. The disappearance of large clades is observed in the fossil record, but our model suggests that it is very improbable without both high overall extinction intensities and high congruence between ecology and phylogeny.

AN - 1712569504; PQ0001954302 AB - Fifty years ago, Baker and Fedorov proposed that the high species diversity of tropical forests could arise from the combined effects of inbreeding and genetic drift leading to population differentiation and eventually to sympatric speciation. Decades of research, however have failed to support the Baker-Fedorov hypothesis (BFH), and it has now been discarded in favor of a paradigm where most trees are self-incompatible or strongly outcrossing, and where long-distance pollen dispersal prevents population drift. Here, we propose that several hyper-diverse genera of tropical herbs and shrubs, includingPiper(>1,000 species), may provide an exception. Species in this genus often have aggregated, high-density populations with self-compatible breeding systems; characteristics which the BFH would predict lead to high local genetic differentiation. We test this prediction for fivePiperspecies on Barro Colorado Island, Panama, using Amplified Fragment Length Polymorphism (AFLP) markers. All species showed strong genetic structure at both fine- and large-spatial scales. Over short distances (200-750 m) populations showed significant genetic differentiation (Fst0.11-0.46,P1,000 species), may provide an exception.

Based on concentrations of the cosmogenic radionuclides (super 10) Be, (super 26) Al, (super 36) Cl, and (super 41) Ca in the metal and stone fraction of 16 QUE L5 or LL5 chondrites, we conclude that 13 meteorites belong to a single meteorite shower, QUE 90201, with a large preatmospheric size and a terrestrial age of 125 kyr. Members of this shower have properties typical of L (e.g., pyroxene composition) and LL chondrites (e.g., metal abundance and composition), as well as properties intermediate between the L and LL groups (e.g., olivine composition), and is thus best described as an L/LL5 chondrite. Based on comparison with model calculations, the measured radionuclide concentrations in the metal and stone fractions of QUE 90201 indicate irradiation in an object with a preatmospheric radius of approximately 150 cm, representing one of the largest chondrites known so far. Based on the abundance of small L5 and LL5 chondrites at QUE and their distinct mass distribution, we conclude that the QUE 90201 shower includes up to 2000 fragments with a total recovered mass of 60-70 kg, <% of the preatmospheric mass of approximately 50,000 kg. The mass distribution of the QUE 90201 shower suggests that the meteoroid experienced catastrophic atmospheric fragmentation(s), either because it was a fragile object or it had a high entry velocity.

It is therefore important to explore how the warmer and more acidic oceanic conditions predicted for the future could affect these processes. This study used controlled culture to investigate the effects of a 1 degree C increase in temperature and a 0.2-0.25 unit decrease in pH on the settlement and survival of planulae and the growth of primary polyps in the Tropical Eastern Pacific coral Porites panamensis. We found that primary polyp growth was reduced only marginally by more acidic seawater but the combined effect of high temperature and lowered pH caused a significant reduction in growth of primary polyps by almost a third. Elevated temperature was found to significantly reduce the amount of zooxanthellae in primary polyps, and when combined with lowered pH resulted in a significant reduction in biomass of primary polyps. However, survival and settlement of planula larvae were unaffected by increased temperature, lowered acidity or the combination of both. These results indicate that in future scenarios of increased temperature and oceanic acidity coral planulae will be able to disperse and settle successfully but primary polyp growth may be hampered. The recovery of reefs may therefore be impeded by global change even if local stressors are curbed and sufficient sources of planulae are available. We test settlement and growth of Porites panamensis in warmer and more acidic seawater. Separately, neither warmth nor acidity hindered coral settlement. When combined, warmth and acidity reduced growth by a third. Coral growth will be severely impeded under warmer more acidic conditions.

These disks are thought to evolve through gravitational encounters and physical collisions between single planetesimals. In recent years, many binary planetesimals (BPs) have been observed in the solar system, indicating that the binarity of planetesimals is high. However, current studies of planetesimal disk formation and evolution do not account for the role of binaries. Here, we point out that gravitational encounters of BPs can have an important role in the evolution of planetesimal disks. BPs catalyze close encounters between planetesimals and can strongly enhance their collision rate. Binaries may also serve as an additional heating source of the planetesimal disk, through the exchange of the binaries gravitational potential energy into the kinetic energy of planetesimals in the disk.

However, most assessments have addressed individual sites or regional taxon pools, with few comparisons of differences in assemblage composition within or among regions. We examined the effects of anthropogenic disturbance on local richness ( alpha alpha diversity) and species turnover ( beta beta diversity) of benthic macroinvertebrates in small streams within and between 2 ecoregions (Northern Piedmont vs Southeastern Plains ecoregions) of the Patuxent River basin (Maryland, USA). Regional species pools did not differ between ecoregions (Piedmont == 166 taxa, Plains == 162 taxa); however, local richness was lower in the Plains (mean == 17.4 taxa/stream) compared to the Piedmont (mean == 22.2 taxa/stream). When streams were categorized into disturbance classes (low, medium, high), local richness did not differ among categories for either region. However, at the entire Patuxent scale, local richness tended to decrease with %% impervious cover in a watershed. Variation in species composition, analyzed with nonmetric multidimensional scaling (nMDS), differed significantly between Piedmont and Plains streams, and Plains streams had higher beta beta diversity than Piedmont streams. When partitioned by disturbance category and region, beta beta diversity differed only between the low-disturbance sites (Plains > Piedmont). Relationships between beta beta diversity and environmental variables varied by region. beta beta diversity was weakly negatively related to %% row-crop cover in a watershed at the entire Patuxent scale. For the Piedmont region, beta beta diversity tended to decrease with %% forest, %% pasture, and %% row-crop cover in a watershed. Such negative relationships between beta beta diversity and landuse variables indicate a possible homogenization of the assemblage. The incongruence between diversity measures and composition measures, together with differing effects of anthropogenic land use on beta beta diversity in the 2 regions, emphasizes the need to incorporate both alpha alpha and beta beta diversity and regional environmental factors in conservation/land management studies.

We used deoxyribonucleic acid (DNA) barcoding to expedite identification of larval caddisflies from 20 sites in the headwaters of the Tigris River in northern Iraq by comparing their mitochondrial cytochrome c oxidase subunit I (COI) sequences to a global reference library (the Trichoptera Barcode of Life). We obtained full-length DNA barcodes for 16 COI haplogroups from 11 genera in 9 Trichoptera families. The most haplogroups and genera were recorded from Sulaimani Province. Two distinct COI haplogroups were found for the genus Psychomyia, and 5 haplogroups were found for Hydropsyche. The Hydropsyche COI haplogroups do not form a monophyletic clade with reference to the world fauna, but 4 out of 5 haplogroups are related to other Palearctic species.

To quantify these spatial effects, it is necessary to obtain an ice load model that is both spatially realistic and regionally complete. We demonstrate a technique to produce such a model for the Alaskan glaciers by combining mass balance rates from a Gravity Recovery and Climate Experiment (GRACE) mascon solution with realistic glacier geometries. This load model can be used to solve the "sea level equation" to determine gravitationally self-consistent sea level and gravity rates. The model predicts a significant drop in relative sea level in the near field of the glaciers, with coastal rates of around -9 mm/yr (compared to a global average rise of 0.2 mm/yr) and significant differences to those predicted by a coarser model. The magnitude and sensitivity of these near-field rates imply that the near-field tide gauge records could contain significant information about the spatial distribution of ice loss. Comparison of model gravity rates with an independently produced, spherical harmonic, GRACE solution verifies that our technique can successfully capture the mass changes estimated in the mascon solution within our higher-resolution model. Finally, we use our ice load model to examine the possibility of detecting the effects of ice loss in estimates of ocean bottom pressure (OBP) from GRACE. We use the model to simulate the effects of GRACE signal leakage and show that the OBP signal from leakage has a similar pattern to, but larger amplitude than, the sea level "fingerprint" expected from ice loss.

Such mass redistribution produced by SAL effects is shown to be an important component of OBP variability on scales from months to years and to provide for a better description of the OBP annual cycle observed by GRACE (Gravity Recovery and Climate Experiment). The SAL-induced ocean mass variations have magnitudes comparable to the dynamic OBP signals at subannual, annual, and interannual time scales in many ocean regions and should not be ignored in studies of ocean mass. Annual variations account for the most variability in SAL-related mass signals and can be induced by all the loads considered, with hydrology having the largest contribution. At subannual and interannual time scales, impact of hydrology is minimal and variations are mostly related to load changes from ocean dynamics and from changes in atmospheric circulation, depending on ocean region. The results demonstrate that the large-scale SAL effects are not negligible in the analysis of GRACE-derived global observations of OBP. The estimated SAL effects can explain on average 0.2 cm (super 2) (16%) of the variance in the GRACE annual cycle (expressed in terms of equivalent water height), exceeding 1 cm (super 2) in both open ocean and coastal regions with strong annual SAL signals.

It is the core of the spectacular Mesoamerican Reef (MAR) system that includes diverse reef types, previously considered to be among the healthiest in the Caribbean. A combination of overfishing, coastal development, pollution, coral bleaching, disease outbreaks and hurricanes have reduced reef health in the last few decades. The 2010 Report Card issued by the Healthy Reefs for Healthy People Initiative, a collaboration of over 30 international, regional, national and local organizations, found that only 1% of the 130 reefs surveyed are now in 'very good' condition; 8% are 'good' 21% 'fair', 40% 'poor', and an alarming 30% of reefs are now in 'critical' condition. In addition to the overall health of the reef, scientists are concerned about the increasing number of marine species considered in danger of extinction. There are important management efforts underway aimed at stemming the tide of decline. Belize has recently enacted several important fisheries regulations, including the full protection of key reef grazers (parrot fishes), an increase in the area of fully-protected replenishment reserves, and a ban on spearfishing inside all marine reserves. In addition, the Belize Coastal Zone Management Authority and Institute is currently preparing the Coastal Zone Management Plan for Belize. It should be completed by the end of 2012 and will present a balanced approach to sustainable resource use, including marine and coastal zoning schemes.

The stratigraphical and geographical ranges of 847 dinosaurian species are analysed for palaeodiversity patterns and compared to several sampling metrics. The observed diversity of dinosaurs, Theropoda, Sauropodomorpha and Ornithischia, are positively correlated with sampling at global and regional scales. Sampling metrics for the same region correlate with each other, suggesting that different metrics often capture the same signal. Regional sampling metrics perform well as explanations for regional diversity patterns, but correlations with global diversity are weaker. Residual diversity estimates indicate that sauropodomorphs diversified during the Late Triassic, but major increases in the diversity of theropods and ornithischians did not occur until the Early Jurassic. Diversity increased during the Jurassic, but many groups underwent extinction during the Late Jurassic or at the Jurassic/Cretaceous boundary. Although a recovery occurred during the Cretaceous, only sauropodomorphs display a long-term upward trend. The Campanian-Maastrichtian diversity "peak" is largely a sampling artefact. There is little evidence for a gradualistic decrease in diversity prior to the end-Cretaceous mass extinction (except for ornithischians), and when such decreases do occur they are small relative to those experienced earlier in dinosaur evolution.

The age assigned to the Kinney Brick Quarry (early-middle Virgilian) has long been based more on its inferred lithostratigraphic position than on biostratigraphic indicators at the quarry. We have developed three datasets--stratigraphic position, fusulinids and conodonts-that indicate the Kinney Brick Quarry is older, of middle Missourian (Kasimovian) age. Our detailed local lithostratigraphic studies coupled with regional stratigraphic investigations indicate the Kinney Brick Quarry is in the Tinajas Member of the Atrasado Formation, so it is stratigraphically lower than suggested by previously published maps. A laterally extensive fusulinid bearing limestone a few meters be-low the level of the Kinney Brick Quarry yields an early-middle Missourian fusulinid assemblage consisting of Tumulotriticites cf. T. rumidus and species of Tritcites: T. of. T. planus, T. of. T. myersi and T. ex gr. T. ohioensis. The Kinney conodont fauna is characterized by Idiognuthodus corrugatus and I. cherryvalensis, which suggest an assignment to the Idiognothodus confragus Zone of the North America Midcontinent region (Dennis cyclothem; middle Missourian). Nonmarine biostratigraphic indicators at the Kinney Brick Quarry indicate either an imprecise age (Late Pennsylvanian: megaflora) or a slightly younger age (late Kasimovian-early Gzhelian: blattids) than do stratigraphic position and marine microfossils. The well-established age of Kinney on the marine timescale thus can be used to better calibrate the nonmarine biostratigraphy. So, the insect biozonation of the Euramerican continental basins, which was calibrated to the so-called regional West European Carboniferous stages by macrofloras and to the global marine scale by sparse, ambiguous isotopic ages, can now be linked directly to the marine conodont zonation.

Recently, padding has been incorporated to better protect the fossils, but some adhesives commonly used to hold padding are potentially harmful in the microclimate of the clam-shell jacket. We introduce a method which eliminates the use of contact cements and other potentially harmful chemicals. This improved method uses traditional materials--a large sand box (to support the fossil during the process), sand bags (to hold down the edges of the ethafoam), FGR-95 plaster, and a plastic wrap separator (to keep wet plaster from contacting the specimen)--but different techniques. By coarsely sanding one surface of the ethafoam and exposing the surface layer of cells (bubbles), the plaster bonds uniformly to the ethafoam without glues and/or contact cement. Polyfelt bonds well with plaster without sanding, making it an excellent alternative to ethafoam.

Methods of identifying bird remains have recently been enhanced to include the use of molecular techniques but the degraded condition of the field sample remains problematic. The Whatman FTA registered card is a novel way to instantly fix DNA and inhibit degradation of DNA samples post-collection. During 2008-2009, we analyzed >200 FTA cards containing tissue blots, body fluids, or blood samples from bird strikes to evaluate the performance of these cards in real-time situations. We analyzed the success of extracting DNA from the FTA cards, compared the FTA disc punch extractions to dried tissue extractions from the same birdstrike event, and evaluated the blotting density (heavy versus light) for each FTA card punch. FTA cards alone yielded successful extractions in 63% of the trials whereas dried tissue samples were successful 75% of the time. FTA cards that were scored as being blotted with dense (heavy) samples were more successful (63%) than the light or liquid samples (48%). We encourage the use of the FTA cards or similar products as a valid option for the collection of degraded birdstrike remains because the FTA cards resulted in successful extractions in >50% of the cases. The cards are ideal for shipping and require no special storage; the cards are dry and lightweight; immediate fixation of the sample helps prevent mold and bacterial growth; and FTA cards are listed by the U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) as an approved method of treatment for foreign shipments of bird remains.

Animals located on the group edge typically face an increased threat of predation, although different patterns have been reported. We created a simulation model to determine how changes in predator attack distance and prey density influence predation in relation to within-group spatial position. At large attack distances, peripheral animals were attacked far more than central animals. At relatively short attack distances, central individuals were attacked almost as often as peripheral animals. We used 6 different methods to classify within-group spatial position in our simulations and tested which methods were the best predictors of predation risk at different parameter values. The minimum convex polygon and angle of vulnerability methods were the best predictors of predation risk at large and medium attack distances, respectively. At relatively short attack distances, the nearest neighbor distance and neighbor density methods were the best predictors of predation risk. These patterns demonstrate that the threat of marginal predation is dependent on the behavior of predators and that for some predator-prey systems, marginal predation is predicted to be insignificant. We predict that social prey animals should change antipredatory behavior, such as vigilance, within-group spacing, and within-group spatial choice based on the relative distances at which their predators attack. These results demonstrate the importance of incorporating the behavior of predators in empirical studies and predator-prey models.

A common theme is an increase in organismal control over internal physiology and the external environment. Often, these changes have been examined in the context of discrete events (e.g., the Cambrian Explosion, Mesozoic Marine Revolution), but they may represent linked, ongoing megatrends. This review examines changes in ecological composition in the context of changes in taxonomic composition, as represented by a more detailed version of Sepkoski's evolutionary fauna analysis. Ecological change occurred during major radiations and extinctions, as well as between them. Due to its ecological selectivity, the Permian-Triassic extinction had particularly significant ecological effects on the biota. Recoveries from mass extinctions may be important episodes of ecological change. Further research could help elucidate the fundamental causes of long-term ecological change, including any role played by the environment.

The period of carbon release is thought to have lasted <20 ka, the duration of the whole event was approximately 200 ka, and the global temperature increase was 5-8 degrees C. Terrestrial and marine organisms experienced large shifts in geographic ranges, rapid evolution, and changes in trophic ecology, but few groups suffered major extinctions with the exception of benthic foraminifera. The PETM provides valuable insights into the carbon cycle, climate system, and biotic responses to environmental change that are relevant to long-term future global changes.

By simulating the quiescent young Sun and its wind we are able to propagate the MHD simulations up to Earth's magnetosphere and obtain a physically realistic solar forcing of it. We assess how sensitive the young solar wind is to changes in the coronal base density, sunspot placement and magnetic field strength, dipole magnetic field strength, and the Sun's rotation period. From this analysis we obtain a range of plausible solar wind conditions to which the paleomagnetosphere may have been subject. Scaling relationships from the literature suggest that a young Sun would have had a mass flux different from the present Sun. We evaluate how the mass flux changes with the aforementioned factors and determine the importance of this and several other key solar and magnetospheric variables with respect to their impact on the paleomagnetosphere. We vary the solar wind speed, density, interplanetary magnetic field strength, and orientation as well as Earth's dipole magnetic field strength and tilt in a number of steady state scenarios that are representative of young Sun-Earth interaction. This study is done as a first step of a more comprehensive effort toward understanding the implications of Sun-Earth interaction for planetary atmospheric evolution.

We have elsewhere demonstrated that heterogeneity in food availability drives the movement decisions of site-persistent and itinerant individuals during the nonbreeding period. Here, we show that intraspecific competition played an important role in determining where individuals initially and eventually settled. Territoriality, characterized by aggression, site-persistence, and exclusive home ranges, was more often found in males. Territorial birds gained mass over the winter, whereas birds that made midseason home-range shifts or that had home ranges with high intraspecific overlap tended to lose mass over the winter. The benefits associated with territoriality may be the result of maintaining higher-quality territories that were both wetter and had higher food availability than less exclusive home ranges. Our results suggest that despotism in the form of territoriality drives patterns of habitat occupancy, and in this system, high-quality habitat appears to be limiting for the Northern Waterthrush. This may have long-term consequences for the success of individual birds, because continued destruction of naturally limited habitats such as coastal mangroves, and predictions of a drying climate on wintering areas, have the potential to severely affect populations.

AN - 893282246; 15631105 AB - The unique wildlife of the Ewaso Nyiro and valuable services that the ecosystem provides for humans (e.g., clean water and productive grasslands) cannot be conserved by working solely on traditional conservation strongholds such as the national reserves and private ranches of central Laikipia. To reach objectives for conserving wildlife, stakeholders must work to preserve wildlife habitat and corridors in the surrounding human-dominated landscape--a daunting task considering the complexity of working at large spatial scales (e.g., many landowners, competing land uses) and limited conservation resources available. Systematic, landscape-scale conservation planning helps stakeholders set meaningful and transparent objectives, identify where to work to meet those objectives, and prioritize areas for immediate investment. We describe results and implications of an initial landscape-scale planning exercise for the Ewaso Nyiro that culminated in a workshop in January 2006. Forty participants selected nine focal features, set quantitative objectives for four of them (elephants, Grevy's zebra, lions, wild dogs), and set spatial conservation priorities for the entire landscape on the basis of complementary needs of critical species. The modest objectives for these species (e.g., maintaining a population of 300 wild dogs) cannot be met by conservation focused solely on traditional strongholds. The exercise indicated that nearly 84% of the landscape needs conservation investment, and it identified three near-term priorities: (1) maintain current investments in conservation strongholds, (2) increase investment to secure the narrow corridor between Samburu and Laikipia Districts, and (3) increase investment to secure portions of Samburu District, including the Matthews Range. The results we describe represent the initiation of a land use planning process that, if continued, can help meet both biodiversity and livelihood development objectives. We recommend this process be carried forward in the Ewaso Nyiro and then in similar ecosystems in Kenya and eastern Africa.

To maintain viable populations of native wildlife, lands outside protected areas must be conserved through innovative measures. This paper describes the legal framework for landownership in Kenya and existing legal mechanisms used to conserve wildlife habitat and recommends new tools for land conservation on private land. We stress that none of the existing land tenure systems provide an absolute right of use and that most existing legal mechanisms for conservation cannot be relied upon to effectively conserve wildlife habitat outside protected areas. Although environmental statutes such as the Forests Act (Laws of Kenya, 2005) prescribe conservation guidelines, most environmental legislation in Kenya relies upon enforcement and compliance. This approach is not effective because of the lack of institutional capacity to enforce. Because existing measures are not sufficient, other mechanisms such as environmental easements, land purchase, and conservation leases are urgently needed. Even if Kenya's environmental legislation was fully enforced and implemented, environmental easements, land leases, and land purchase would still be vital tools for conservation. Although these tools have great promise, they have not been widely used in Kenya because of legal limitations and lack of precedence. Legislative change and the testing of these tools through existing statutes are required to enable their broader application in Kenya. The Kenya Land Conservation Trust is introduced as an institution providing the framework and structure to utilize conservation mechanisms, such as environmental easements.

Finding solutions for the coexistence of people with predators in the Ewaso region is of great importance for the local tourism industry and for the persistence of Kenya's wildlife outside of protected areas. We report results of an assessment of attitudes toward predators by landholders and land users in the Ewaso region and their tolerance of livestock losses, relative to socioeconomic factors. Although prospects are good for predator conservation on large-scale private ranches, the future of predators on communally owned properties remains uncertain. Prospects would be improved not only by finding solutions to reduce livestock depredation but also by ensuring that individuals tolerating losses from predators receive benefits from having predators on their land. Additionally, policy changes are needed to allow landholders to capitalize on benefits from wildlife, which would encourage their participation in wildlife conservation.

Lions have been eliminated from agricultural areas, and pastoralists have lost tolerance for predators; ready availability of cheap and effective poison poses a critical threat to their survival in Kenya outside of the largest national parks. However, lions still thrive on the commercial ranch-lands of Laikipia District, where landowners use traditional low-cost African methods of livestock husbandry to effectively protect domestic stock from predators. Thus, Laikipia has been an ideal laboratory in which to investigate the ecology of predators living in human-dominated landscapes and factors in management of both livestock and lions which allow coexistence between them. Although socioeconomically unrepresentative of most African rangelands, the Laikipia experience shows that it is easy to raise livestock in the presence of viable populations of large carnivores if people have incentive and motivation to take basic, traditional measures to keep them apart. The current lack of financial incentives for rural Kenyans to tolerate wildlife, however, may limit the usefulness of the Laikipia model to privately owned lands.

Here we synthesize research on rangelands in central Laikipia focusing on two types of cattle-wildlife interactions that have implications for their long-term coexistence. The first interaction occurs via redistribution of soil nutrients within the ecosystem, which is a consequence of the use of bomas (temporary corrals) to manage livestock. Our studies on two different soil types show that rotational boma management creates hectare-scale patches in the landscape that are enriched in soil and plant nutrients and persist for decades to centuries. In both of the predominant soil types in Laikipia, forage phosphorus content is low relative to ungulate demands during peak lactation. Nutrient-rich boma sites (hereafter referred to as glades) provide a key wet-season forage resource of nutritional sufficiency for lactation. Our studies further show that a wide range of native ungulates selectively use glades relative to surrounding nutrient-poor habitats. Impala (Aepyceros melampus) in particular show intensive use of glades on sandy soils and are rare in portions of the landscape lacking glades. A second important pathway for cattle-wildlife interaction occurs through the influence of native browsing ungulates on woody vegetation. Shrub and tree cover has been increasing in Laikipia over the past century, followed by increases in native browsers in recent decades on ranches where wildlife are allowed to coexist with cattle. Our exclosure experiments in central Laikipia indicate that native browsers suppress shrub encroachment on both dominant soil types. However, the strength of browser effects are three to seven times greater on sandy soils, where two browsers, dik-dik and elephants, are both abundant, compared to heavy clay soils, where elephants are the only dominant browser. In the clay soils, native browsers still exert a significant influence on dynamics of the dominant tree, Acacia drepanolobium, and suppress encroachment by subdominant shrub species. Browser effects on woody vegetation likely enhance forage production for cattle and maintain open habitats favored by native grazers for predator avoidance. Taken together, our studies indicate that boma rotation and browser control of shrub encroachment are key interaction pathways that promote cattle-wildlife coexistence in the Ewaso ecosystem.

Their indirect interactions, both as key consumers within food webs and as "engineers" of habitat structure, are less well understood. Here we review the results of nearly 15 years of experimental research at Mpala Research Centre (Laikipia, Kenya), focusing primarily on the indirect effects of ungulates on the abundance, distribution, and diversity of other species. We highlight several broad conclusions: (1) ungulate exclusion increases densities of plants and many small consumers; (2) the strength of these indirect effects is context dependent and may vary systematically along environmental gradients; (3) impacts of different ungulate species vary both quantitatively and qualitatively. Although some of the observed effects of ungulate exclusion were predictable, others were surprising. These insights are obliquely relevant to management, but there remains a mismatch between the kinds of information most interesting to academics on the one hand and most useful to land mangers on the other. We conclude by identifying some areas of likely convergence between questions of basic and applied importance.

First, we use results from high-resolution sample surveys in Laikipia District (northern Kenya) to directly compare results from aerial total and sample surveys, showing few systematic differences in their estimates of wildlife abundance but great differences in cost and scope. Second, we quantify how the precision of population estimates is affected by survey resolution and species density. Results suggest that lower survey resolutions widely used in the past to census wildlife and livestock resources have been insufficient to reliably estimate all but the most abundant species. Third, we describe how sample survey data can be used to map the potential for human-wildlife conflict across large landscapes. High-resolution sample surveys in Laikipia have revealed causes and consequences of ecosystem change, advanced our understanding of ungulate population dynamics, guided wildlife management and conservation action, and increased confidence in sample survey methodology. However, further refinements in sample survey methods are needed to improve cost-effectiveness.

Overall, the evidence indicates that many different groups have occupied parts of this area at different times in the past, and that these have encompassed both hunter-gatherer and pastoralist communities and speakers of various Nilotic, Cushitic, and Bantu languages, among others. There is also good evidence to suggest that the boundaries between different "ethnic," "subsistence," and even linguistic groups have been fairly fluid and that cultural intermixing as well as interaction through exchange and other social mechanisms was common. Additionally, at least four broad phases of pastoralist practices can be identified for the period prior to the twentieth century. These phases entailed different forms and levels of mobility, including population migration and seasonal movements, and had diverse environmental consequences, some of which appear to have enhanced biodiversity and ecological resilience whereas others initiated significant changes to the structure of the vegetation mosaic and may have even resulted in localized rangeland degradation.

The first is that directly or indirectly, they all address aspects of what in recent decades has become a global environmental imperative, generally referred to as "landscape conservation." The second is that all chapters focus geographically on the Ewaso landscape in northern Kenya (defined in Box 1; outlined by a rectangle in the inset of Figure 1), where concerted and prodigious efforts to conserve wildlife and natural resources over the last 20 years have achieved substantial progress. This work is not a "how-to" handbook, nor does it aim to cover all aspects of this increasingly complex and multifaceted endeavor. Rather, it provides an opportunity to document progress in ways intended to facilitate further advancement toward landscape conservation in this and other regions like it.

The majority of birds (69%) were sedentary and used a contiguous area within a single habitat over the winter period. A smaller percentage (31%) initially used a contiguous area within a single habitat but then permanently moved from that area to another disjunct location (mean = 418 m). Most of these movements were out of the two habitats (dry forest and Black Mangrove) that became the driest from January to mid-March and into wetter mangrove areas. The primary determinants of movement probability were moisture and food availability on each bird's home range. Foraging areas of birds that eventually moved were drier and had lower food availability than areas used by site-persistent individuals. The sites that these itinerant birds moved to were wetter and had higher food availability, which suggests that individuals moved in response to changing resources. Our results (1) indicate that habitats used by this species differ in suitability and (2) support previous findings that turnover rates within a habitat could serve as an indicator of habitat quality. The ability to predict behavioral responses of individuals to habitat conditions that vary across space and time is essential for understanding individual and population responses to habitat loss and the effects of a changing climate in the New World tropics.

The Antarctic region is a "natural laboratory" for scientific research of importance in its own right and impossible to achieve elsewhere on the planet. Understanding the Earth system, its components, connections and feedbacks is a major endeavour of contemporary Antarctic science. The following on-going and emerging research activities will be a continued focus of Antarctic research in the coming years: past, current and future climate change; the systematic response of Antarctica to change; understanding Antarctic biodiversity, evolution and ecology; exploration and modelling of ice dynamics and sub-ice environments; ocean, ice, atmospheric and cryospheric observing and modelling; linkages and teleconnections between polar regions and the Earth system; and the poles as a vantage point to observe Earth, near-Earth space, the Solar System and beyond. The Scientific Committee on Antarctic Research (SCAR) is a leader in facilitating international, interdisciplinary science in Antarctica, and through its portfolio of scientific projects, committees, and programs provides a venue for partnerships and exchange of the latest findings. The SCAR accomplishes its scientific mission in close partnership with a wide range of organizations, including the Council of Managers of National Antarctic Programs, the Convention for the Conservation of Antarctic Marine Living Resources, the Scientific Committee on Oceanic Research, the Association of Polar Early Career Scientists, and the International Arctic Science Committee. The SCAR works to ensure that maximum value is derived from the Antarctic research. Emerging frontiers and new directions in Antarctic science continue the historical recognition of the value of the Antarctic as a reserve for science and peace.

As a body of the International Council for Science (ICSU, formerly the International Council of Scientific Unions) it is a nongovernmental organization, yet it has been intimately linked to the governmental discussions at the Antarctic Treaty since the first Antarctic Treaty meeting in 1961. Its primary role has always been to develop and coordinate international scientific research, but it has also provided independent advice to Treaty Parties on many scientific and environmental questions, initially through national government delegations. Only in 1987 was SCAR itself granted the status of observer and the right to attend Antarctic Treaty Consultative Meetings (ATCMs) and to submit information and working papers. This paper looks at the changing relationship between SCAR and the Treaty Parties, at some of its most important science inputs to the ATCM, and at the way SCAR itself has changed. Its earliest input to governance was advice on conservation that became the Agreed Measures for the Conservation of Antarctic Fauna and Flora of 1964, and for the first 40 years of the Antarctic Treaty, SCAR provided major input on protected areas and protected species, as well as environmental impact and monitoring. Its proposals for seal conservation and management gave it a specific role in the Convention for the Conservation of Antarctic Seals, and its Biological Investigations of Marine Antarctic Systems and Stocks (BIOMASS) programme laid the foundations for the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR). Its nonpolitical stance has allowed it to provide the only unified gazetteer for the Antarctic. The organization of SCAR remained virtually unchanged for around 30 years until the logisticians split to form the Council of Managers of National Antarctic Programs (COMNAP) in 1989. The organization was languishing, but a major review of structure and function changed that in 2000, resulting in the establishment of Open Science Conferences, major new international programmes, increased educational outreach, and a greater input to the annual Antarctic Treaty meetings, often on controversial subjects like marine acoustics or specially protected species. There are currently 31 full members with 4 associate members and 9 ICSU union members.

Over the last 50 years, the Antarctic Treaty has preserved the Antarctic continent as a zone of peace and cooperative scientific research and provided an effective model for the management of regions beyond the limits of national jurisdiction according to common values. The reasons for this success are, however, by no means obvious to the casual observer. The language of the treaty itself and of the related conventions on seals, marine living resources, and minerals and the Protocol on Environmental Protection is deliberately ambiguous and vague. The regime has weak inspection, enforcement, and governance mechanisms and has been slow to respond to conflict in the Southern Ocean over whaling and unregulated fishing. A key to understanding both the successes and limitations of the ATS lies in the differing juridical positions of the member states on sovereign claims to Antarctic territory. Every ATS agreement, measure, and decision and state practices in respect to Antarctica should be viewed through the prism of these national perspectives on sovereignty. This paper sets out the evolution of the ATS and explores the fundamental role of Article IV and "sovereign neutrality" as the glue that binds the Antarctic Treaty and its interlinked measures, decisions, and agreements. Article IV has enabled the Consultative Parties to sidestep potential conflicts over territorial claims and to manage activities in Antarctica in the wider interests of the international community. For the second decade of the twenty-first century, the vital question is whether the ATS is capable of responding effectively to the challenges posed by illegal fishing and whaling, climate change, commercial tourism, energy, and human security. The litigation in the Japanese Whaling case, brought by the Humane Society International in the Australian Federal Court, provides a salutary warning of the risks to the ATS of unilateral assertions of national jurisdiction over activities in the Antarctic region. The Consultative Parties are now on notice to justify the legitimacy of their mandate and to demonstrate the capacity of the ATS to respond to contemporary Antarctic issues. The 50-year historical evolution of the ATS and its demonstrated capacity for dynamic growth suggest that the regime and its members have the flexibility and political will to maintain its success in the future.

It will inevitably touch upon both substance (what has been achieved under the Antarctic Treaty) and process (how it has been achieved). As such, it will address the story of the development of the Antarctic Treaty into what is now known as the Antarctic Treaty System.

Exchanges of scientists have occurred among many nations over the last 50 years, but increasing planning and logistics collaboration have marked the achievement of many major scientific goals possible only through multinational activity. The recently completed International Polar Year provides clear evidence of how well this is succeeding in Antarctic science for the twenty-first century, and the publication record clearly reflects this pooling of talent.

The project laid the groundwork for circum-Antarctic seismic, drilling, and rock coring programs designed to decipher Antarctica's tectonic, stratigraphic, and climate histories. In 2002, ANTOSTRAT evolved into the equally successful and currently active Antarctic Climate Evolution research program. The need for, and evolution of, ANTOSTRAT was based on two simple tenets within SCAR and the Antarctic Treaty: international science collaboration and open access to data.

The linking of individuals or populations of a given species within its range, including its breeding, migration, and wintering areas, is known as migratory connectivity. In this Article, we discuss how new technologies and approaches are enhancing our knowledge of migratory connectivity, which in turn can improve our legal and policy approaches to the conservation of migratory animals. Advances in studying and documenting migratory connectivity require new approaches to the design and implementation of both domestic and international conservation efforts. Understanding migratory connectivity of different populations of species between specific geographic locations can also help build "social connectivity" for conservation--the cultural, educational, economic, and institutional linkages between these same locations that are a necessary foundation for effective and sustainable conservation efforts.

We compared reproductive success of group living and solitary adult male coatis to determine the degree to which sociality affects reproductive success. Coati mating is highly seasonal and groups of female coatis come into oestrus during the same 1-2week period. During the mating season, solitary adult males followed groups and fought with the group living male. This aggression was presumably to gain access to receptive females. We expected that high reproductive synchrony would make it difficult or impossible for the one group living male to monopolize and defend the group of oestrous females. However, we found that group living males sired between 67-91% of the offspring in their groups. This reproductive monopolization is much higher than other species of mammals with comparably short mating seasons. Clearly, living in a group greatly enhanceda male's reproductive success. At the same time, at least 50% of coati litters contained offspring sired by extra-group males (usually only one offspring per litter); thus, resident males could not prevent extra-group matings. The resident male's reproductive advantage may reflect female preference for a resident male strong enough to fend off competing males.

These 19 species are described or redescribed and figured unless recent descriptions have been published. Eight new species are described, two in the genus Thouarella and six in the genus Plumarella. These two genera are redefined and differentiated by emphasizing the nature (keeled or not) of the inner side of their marginal scales and the inner side's articulation or lack thereof with the outer surface of the underlying opercular scales. Dicholaphis is proposed as a new subgeneric rank of the genus Plumarella, characterized by having polyps arranged on all sides of its branchlets, not on alternate opposite sides. A key is provided for the eight species of Aleutian Plumarella, and all 35 valid species in the genus are listed, including three new combinations: P. superba, P. abietina, and P. recta. A history of the Aleutian primnoids is recounted. Six primnoid species are reported from the Bering Sea, all of which also occur in the Aleutian Islands. Two-thirds of the Aleutian-Bering Sea primnoids are endemic to this region.

Over the past 32years, Amazonian forest fragments ranging from 1 to 100ha have experienced a wide array of ecological changes. Edge effects have been a dominant driver of fragment dynamics, strongly affecting forest microclimate, tree mortality, carbon storage, fauna, and other aspects of fragment ecology. However, edge-effect intensity varies markedly in space and time, and is influenced by factors such as edge age, the number of nearby edges, and the adjoining matrix of modified vegetation surrounding fragments. In our study area, the matrix has changed markedly over the course of the study (evolving from large cattle pastures to mosaics of abandoned pasture and regrowth forest) and this in turn has strongly influenced fragment dynamics and faunal persistence. Rare weather events, especially windstorms and droughts, have further altered fragment ecology. In general, populations and communities of species in fragments are hyperdynamic relative to nearby intact forest. Some edge and fragment-isolation effects have declined with a partial recovery of secondary forests around fragments, but other changes, such as altered patterns of tree recruitment, are ongoing. Fragments are highly sensitive to external vicissitudes, and even small changes in local land-management practices may drive fragmented ecosystems in markedly different directions. The effects of fragmentation are likely to interact synergistically with other anthropogenic threats such as logging, hunting, and especially fire, creating an even greater peril for the Amazonian biota.

Many obvious georeference errors, for example, that map land animals over sea, the wrong hemisphere, or the wrong country, may be avoided if collectors and data providers could easily map their data points prior to publication. Various tools are available for quality control of georeference data, but many involve an investment of time to learn the software involved. This paper presents a method for the rapid map display of longitude and latitude data using the chart function in Microsoft Office Excel registered , arguably the most ubiquitous spreadsheet software. Advantages of this method include: use of software that will be familiar to many data providers, immediate visual feedback to assess data point accuracy; and results that can be easily shared with others. Methods for making custom Excel chart maps are given, and we provide free charts for the world and a selection of countries at http://www.vectormap.Org/resources.htm.

Plant defences are predicted to increase from dry to wet forests, rendering wet-forest caterpillars more vulnerable to parasitoids due to the slow-growth-high-mortality hypothesis. We collected and reared caterpillars from the understorey and trail edges of a wet forest and a seasonally dry forest to determine whether wet-forest caterpillars suffered a higher prevalence of parasitism and were less abundant than dry-forest caterpillars. In the two forests, caterpillar abundances (on average 8 h-1) and prevalence of parasitism (18%) were very similar regardless of feeding niche for both parasitism (27% versus 29% in shelter builders, and 16% versus 11% in external feeders) and caterpillar abundances (shelter builders: 1.42 versus 2.39, and external feeders: 8.27 versus 5.49 caterpillars h-1) in the dry and wet forests, respectively. A similar comparative analysis conducted in the canopy and understorey of the dry forest revealed a higher prevalence of parasitism in the canopy (43%) despite caterpillar densities similar to those in the understorey. Overall, shelter builders suffered higher parasitism than external feeders (32% versus 14.9%), and were attacked primarily by flies, whereas external feeders were more vulnerable to attack by parasitoid wasps.

Given that further studies on this topic are likely (there are probably millions of species showing rapid genital divergence), I discuss the studies critically to promote clear formulation of hypotheses and interpretation of results in the future. I also emphasize some possibly important but neglected variables, including female stimulation, phylogenetic contexts, and the behavior of male genitalia, and outline simple techniques that could improve future studies.

We assessed patterns of genetic structure in the giant tortoise of the Aldabra atoll, where previous ecological studies suggested population subdivisions as a result of landscape discontinuity due to unsuitable habitat and island separation. Analysis of mitochondrial DNA (mtDNA) control region sequences and allelic variation at 8 microsatellite loci were conducted on tortoises sampled in 3 locations on the 2 major islands of Aldabra. We found no variation in mtDNA sequences. This pattern corroborated earlier work supporting the occurrence of a founding event during the last interglacial period and a further reduction in genetic variability during historical time. On the other hand, significant population structure recorded at nuclear loci suggested allopatric divergence possibly due to geographical barriers among islands and ecological partitions hindering tortoise movements within islands. This is the first attempt to study the population genetics of Aldabra tortoises, which are now at carrying capacity in an isolated terrestrial ecosystem where ecological factors appear to have a strong influence on population dynamics.

Data were collected from a single crystal using a MoKalpha source and a CCD detector, solved by direct methods, and refined to an R factor of 2.81%. The mineral structure consists of hexaborate fundamental building blocks that polymerize along [001] and are bound by Ca (super 2+) and REE (super 3+) counter-ions. The framework forms hexagonal channels, which are occupied alternately by Ca (super 2+) cations and water molecules. In an investigation of its thermal stability, braitschite maintains its crystallinity to a temperature of 400 degrees C, after which it undergoes decomposition. Using Rietveld refinements against powder X-ray diffraction data, we were able to track the loss of water molecules in channels and hydroxyl groups in the covalent B-O network with increasing temperature.

Extinction of the large and distinctive planktic foraminifer Paraticinella eubejaouaensis, used to denote a level at or near the Aptian/ Albian boundary, coincides with the extinctions of relatively long-ranging Aptian species of Hedbergella and Globigerinelloides. At Deep Sea Drilling Project (DSDP) Site 511 (southern South Atlantic), which is the most complete and best preserved of the studied AABI sections, the Aptian assemblage is of low diversity and species are replaced by initially one and then two very small, smooth-surfaced, thin-walled species of Microhedbergella n. gen. The oldest species of this genus, Mi. miniglobularis n. sp., probably descended from Hedbergella praelippa n. sp. and is the nominate taxon for a new lowermost Albian interval zone and is considered ancestral to several small, gradually evolving microperforate species, including Mi. praeplanispira n. sp., Mi. pseudoplanispira n.sp., and Mi. pseudodelrioensis n. sp., which range into the middle and upper Albian. The small hedbergellids that characterize the Mi. miniglobularis Interval Zone at Site 511 have also been identified from samples taken just above the Kilian black shale level in the Vocontian Basin of southeast France. The Albian record at Site 511 reveals a gradual increase in planktic foraminifera shell size and assemblage dominance, as well as the gradual evolution during the middle Albian of species characterized by a finely perforate, pustulose test. Taxa with this shell infrastructure are included in Muricohedbergella n. gen. A new "Ticinella yezoana" Partial Range Zone is erected at Site 511 for correlation of the middle-upper Albian at high latitudes. At Ocean Drilling Program (ODP) Site 1049 (western North Atlantic), which also yields well-preserved foraminifera across the AABI, Aptian species of Hedbergella, Globigerinelloides, and Pseudoguembelitria blakenosensis n. gen., n. sp. are replaced by lower Albian assemblages composed only of two minute species of Microhedbergella. However, this boundary section is considered incomplete because of the absence of the Mi. miniglobularis Zone. A new upper lower Albian Ti. madecassiana Zone is defined at Site 1049 for the interval between the lowest occurrence (LO) of the nominate taxon and the LO of Ti. primula, the nominate species of the middle Albian Ti. primula Zone. The AABI at DSDP Site 545 (eastern North Atlantic) has a major unconformity spanning the uppermost Aptian through the upper Albian. A black shale sequence previously placed in the lower Albian and designated as Oceanic Anoxic Event 1b is now determined to be latest Aptian in age. The AABI at ODP Site 763 (southeast Indian Ocean) is also marked by an unconformity between the upper Aptian Pa. eubejouaensis Zone and the lower Albian Mi. rischi Zone. This site needs further study to resolve whether overlap of species from both zones is the result of downslope reworking or an exception to the pattern of abrupt species turnover observed at the other deep-sea sites. The dramatic changes in planktic foraminiferal assemblages across the AABI suggest major changes in carbonate chemistry, vertical stratification, or productivity in the surface mixed layer occurred during the last 1 myr of the Aptian. Understanding the cause or causes for these changes will require much further investigation.

Nueces Bay receives freshwater from the Nueces River, which enters on the southwest shore. From 2002-2007 foraminifera were sampled on a mid-bay, north-south transect at five different stations. The populations were sampled during periods of low inflow (2002), high inflow (2003), and then low/moderate inflow (2007). During low inflow, the Central Power and Lighting Plant (CPL) was in operation at the south shore, pumping heated, more saline coolant water into the bay. Salinities were nearly constant, ranging from 23-27 at the stations, population densities were low, and there was a high incidence of shell dissolution. The high-inflow samples were taken after the CPL closed and the area received abundant precipitation, with salinities in the bay varying from 12 at the south shore to 21 at the north shore. Foraminiferal abundance was 6-98x greater than it was during low inflow, and there was a low percentage of shell dissolution. With lowmoderate inflow, salinities were from 21-30, densities were somewhat higher than those observed during low inflow, and shell dissolution again increased. Statistical analysis of all three discharge periods shows that population density varies with flow regime. At low and low/moderate discharge there are pronounced density differences among the stations, with higher densities near river input. At high discharge, population density is high at each station. This study establishes the receptivity of foraminifera to relatively short-term changes in freshwater inflow, and highlights their value for monitoring the effects of inflow on biota in Texas estuaries. The unique geographic distribution of each species may be a characteristic that imparts species resilience through time.

In the present study, such high quality images obtained in plan and oblique views are used primarily for archaeological purposes as related to geological (sedimentological and tectonic) parameters. Presented here as example is an area on Calabria's Ionian coastal margin, the Capo Colonna-Punta Scifo shelf platform located off the Crotone peninsula. We show how multibeam sonar can help solve geoarchaeological problems with respect to identification, origin, and subsidence of seafloor structures that were once positioned near a former coastline but now rest at a considerable depth of 12.5-13 m below sea level. MBS images, coupled with diver observations, indicate the structures are of human construction, not of natural origin, and were once part of a now-submerged Greek harbor facility. These structures are positioned on a seafloor that subsided by approximately 10 m since late or post-Greek time; submergence occurred not by mass gravity flow processes, but by a number of tectonic pulses over time that most probably involved lowering by extensional faulting and possible strike-slip events. Linear structural features observed on the seafloor show axial trends similar to those mapped on land, indicating that both subaerial and submerged areas of this Calabrian Arc sector were modified tectonically to the present time. Multibeam data show that this Crotone shelf platform has been subject to considerable structural offset and subsidence on Calabria's Ionian margin since ancient Greek time.

Sediment core analyses and geophysical surveys in this study support recent archaeological findings and the hypothesis that the margin may once have served as a harbor and/or shipyard. The subsurface Holocene stratigraphy records that (1) the shoreline advanced to a maximum landward position before Greek settlement, then regressed offshore to what is now the inner shelf before once again migrating landward. These marked coastal shifts were triggered primarily by land uplift and probable subsidence offshore along this structurally active Calabrian Arc segment. Associated with this are: (2) a sediment fining-upward sequence in Greek-Roman time that indicates only partial protection of the coastal area, and (3) possible presence of subsurface structures seaward of the city wall in a sector now positioned approximately 200 m offshore. 2010 Wiley Periodicals, Inc.

The Choptank's eutrophication problem is a result of nitrogen loading, which occurs mainly as agriculturally-derived nitrate in groundwater discharge. Groundwater can enter the Choptank's tidal waters (including the main stem and the large, tidal tributary Tuckahoe Creek) in two ways: by feeding its small non-tidal tributary streams or by discharging directly into the tidal waters through the river bottom or banks. This study aimed to distinguish these two pathways of groundwater discharge into the Choptank and assess their importance as nitrogen sources. We mapped activities of radon (Rn), a natural tracer of groundwater discharge, in surface waters throughout the navigable extent of the Choptank upstream of Cambridge, MD. In addition, we conducted point sampling of Rn in tidal and non-tidal tributaries throughout the watershed. Salinity, dissolved oxygen, and nitrate concentrations were measured concurrently with Rn. Rn activities generally increased in the upstream direction in the Choptank's tidal waters, suggesting that much of the groundwater input to the river occurs as base flow higher up in the watershed. Anomalously high radon activities suggested possible locations of high groundwater input. Rn activities in small tributaries were generally higher than in tidal waters, but varied by up to two orders of magnitude over a relatively small spatial scale, indicating variability in the magnitude of groundwater discharge, time elapsed since groundwater emerged into surface waters, and/or Rn activity of the groundwater end member. We investigated relationships between nitrate concentrations and Rn activities in groundwater, tributary and tidal water samples. Finally, we used Rn as a natural tracer to estimate groundwater discharge into the Choptank using a tidal prism approach, and also estimated the amount of nitrate loading associated with this discharge.

Timing the exact closure of the Panama Isthmus has remained difficult due to the lack of a well-constrained chronostratigraphic framework for the Panamanian-Colombian area. The Panama Basin is the main tectonic feature separating the Chorotega and Choco-Darien Blocks[1]. Previous investigations have suggested a connection between western Panama and North America at ca 19 Ma; implying disconnection between the Chorotega and Choco-Darien during that time [2]. However, recent geochronologic investigations along eastern and western Panama have suggested a tectonic interaction between Central America - South America at ca 23 Ma [3, 4]. The Darien Formation in the Choco-Darien Block consists of Eocene-Oligocene collisional arc-related volcanics. Exquisitely well-preserved coral reef patchy carbonate successions nonconformably overlay the Darien Formation. Sr-isotope chemostraigraphic data and calcareous nanoplankton suggests a depositional age between 23.3 and 13.65 Ma. The depositional age of such carbonate successions that cover the latest arc record in eastern Panama provides a unique temporal framework for the beginning of Panama-Northern South America tectonic interaction and the resulting Cenozoic paleoceanographic, paleoclimatic and paleobiologic changes in the neotropics.

Maria Elena and Hammond were heated below approximately 700-750 degrees C, so that kamacite was recrystallized and taenite was exsolved in kamacite and was spheroidized in plessite. Both meteorites retained a record of the original Widmanstatten pattern. The other four, which show no trace of their original microstructure, were heated above 600-700 degrees C and recrystallized to form 10-20 mu m wide homogeneous taenite grains. On cooling, kamacite formed on taenite grain boundaries with their close-packed planes aligned. Formation of homogeneous 20 mu m wide taenite grains with diverse orientations would have required as long as approximately 800 yr at 600 degrees C or approximately 1 h at 1300 degrees C. All six irons contain approximately 5-10 mu m wide taenite grains with internal microprecipitates of kamacite and nanometer-scale M-shaped Ni profiles that reach approximately 40% Ni indicating cooling over 100-10,000 yr. Un-decomposed high-Ni martensite (alpha 2) in taenite-the first occurrence in irons-appears to be a characteristic of strongly reheated irons. From our studies and published work, we identified four progressive stages of shock and reheating in IVA irons using these criteria: cloudy taenite, M-shaped Ni profiles in taenite, Neumann twin lamellae, martensite, shock-hatched kamacite, recrystallization, microprecipitates of taenite, and shock-melted troilite. Maria Elena and Fuzzy Creek represent stages 3 and 4, respectively. Although not all reheated irons contain evidence for shock, it was probably the main cause of reheating. Cooling over years rather than hours precludes shock during the impacts that exposed the irons to cosmic rays. If the reheated irons that we studied are representative, the IVA irons may have been shocked soon after they cooled below 200 degrees C at 4.5 Gyr in an impact that created a rubblepile asteroid with fragments from diverse depths. The primary cooling rates of the IVA irons and the proposed early history are remarkably consistent with the Pb-Pb ages of troilite inclusions in two IVA irons including the oldest known differentiated meteorite (Blichert-Toft et al. 2010).

These episodes reflect catastrophic events which may be connected to major plate tectonic reorganizations. U-Pb zircon crystallization from plutonic rocks (30 U-Pb LA-ICP-MS) and detrital zircons (ca. 2000 U-Pb LA-ICP-MS detrital zircon analysis) from northern Colombia have revealed the existence of two major continental magmatic flare ups in the Middle Jurassic (ca. 190-180 Ma) and the Paleogene (60-45 Ma). Their tectonostratigraphic relations suggest that these two episodes are related to different periods of subduction initiation along the Pacific margin of South America. The older is related to an extensional type subduction formed after the break-up of Pangea, whereas the younger Paleogene reflect subduction initiation after arc- continent collision in the Late Cretaceous. These tectonic correlations suggests that the early episodes of subduction in continental margins are responsible for the compositional modification of significant segments of the continental crust.

In the decade and a half since the previous edition was published new studies have refined assessments of the ages of many volcanoes, and several thousand new eruptions have been documented. This edition updates the book's key components: a directory of volcanoes active during the Holocene; a chronology of eruptions over the past ten thousand years; a gazetteer of volcano names, synonyms, and subsidiary features; an extensive list of references; and an introduction placing these data in context. This edition also includes new photographs, data on the most common rock types forming each volcano, information on population densities near volcanoes, and other features, making it the most comprehensive source available on Earth's dynamic volcanism.

This west to east geographic progression from active arc to accreted is also a proxy for the chronology of this arc-continent collisions. The oblique accretion of the Panama arc to northwestern South America is documented with geologic mapping and multidisciplinary analytical studies. A new geologic map with >2000 field stations, 40 petrographic analyses, 24 paleomagnetic sites, and over 30 new geochronological and thermochronological analyses, supports the middle Miocene accretion of the Panama arc to northwestern South America and a late Eocene initiation of tectonic interaction. The extinct arc segment in central Panama arc is composed of a folded-faulted, approximately 3 km-thick basaltic sequence, intruded by granitoid bodies and onlapped by mostly undeformed shallow marine and continental strata. Existing geochronological data, and new whole-rock Ar/Ar (2), and U/Pb zircon ages (6), reveal intense late Paleocene to middle Eocene magmatism, a temporary cessation of magmatic activity between 38 and 28 Ma, and renewed magmatism after 28 Ma in a position approximately 75 km south of the former magmatic axis in central Panama. The geographic patterns of these magmatic pulses is interpreted as a collison that left-laterally offset, and oroclinally bent the axis of the arc, and terminated magmatic activity in the 28 to 38 Ma interval. Magmatic activity restarted after 28 Ma but lasted only until approximately 15 Ma east of the Canal Basin and west of the Uramita suture, defining an arc segment approximately 400 km in length that shows no sign of magmatic activity younger than 15 Ma, probably the result of this part of the arc getting detached and overthrusted the Caribbean Plate to the north. The sigmoidal part of the Panama arc is therefore the result of an extinct arc that has been obliquely accreting to the northwestern margin of South America for the last 15 Ma.

We analyzed both the transit photometry and previously published radial velocities to find the planet-star radius ratio R (sub p) /R (sub *) = 0.07454 + or - 0.00035, inclination i = 86.49 (super +0.24) (sub -0.20) deg, and scaled semimajor axis a/R (sub *) = 23.19 (super +0.32) (sub -0.27) . This last value translates directly to a mean stellar density determination rho (sub *) = 0.522 (super +0.021) (sub -0.018) g cm (super -3) . Analysis of asteroseismology observations by the companion paper of Gilliland et al. provides a consistent but significantly refined measurement of rho (sub *) = 0.5308 + or - 0.0040. We compare stellar isochrones to this density estimate and find M (sub *) = 1.275 + or - 0.018 M (sub []) and a stellar age of 3.37 (super +0.20) (sub -0.47) Gyr. Using this estimate of M (sub *) and incorporating the density constraint from asteroseismology, we model both the photometry and published radial velocities to estimate the planet radius R (sub p) = 1.0870 + or - 0.0066 R (sub J) and the stellar radius R (sub *) = 1.5007 + or - 0.0076 R (sub []) . The planet radius is larger than that found in previous studies and consistent with theoretical models of a solar-composition gas giant of the same mass and equilibrium temperature. For the three transits, we determine the times of mid-transit to a precision of 6.2 s, 7.6 s, and 6.9 s, and the transit times for HD 17156 do not show any significant departures from a constant period. The joint analysis of transit photometry and asteroseismology presages similar studies that will be enabled by the NASA Kepler Mission. Copyright (Copyright) 2011. The American Astronomical Society.

This publication focuses on results obtained from the examination of 121 individuals (78 adults and 43 immature individuals) dating from the 10th century and recovered from the site of Tiszafüred-Nagykenderföldek. These data are compared with those previously published in this project dating from the Neolithic, Copper Age, Bronze Age, Iron Age and the (Early) Árpádian Age, all from northeastern Hungary. Broadly, long-term trends across these ages include increased periosteal lesions, dental hypoplasia in permanent teeth, trauma and antemortem tooth loss, which could be related to correspondingly increased life expectancy. Notably, results suggest that temporal change within these populations was minimal, straying from the pattern of increased morbidity and mortality following sedentism found in the Americas.

Similarly, the carbon isotopic composition in the skeletons record delta (super 13) C values of ambient seawater dissolved inorganic carbon. Here, we measured delta (super 13) C in the coralline alga Clathromorphum nereostratum to test the feasibility of reconstructing the intrusion of anthropogenic CO (sub 2) into the northern North Pacific Ocean and Bering Sea. The delta (super 13) C was measured in the high Mg-calcite skeleton of three C. nereostratum specimens from two islands 500 km apart in the Aleutian archipelago. In the records spanning 1887 to 2003, the average decadal rate of decline in delta (super 13) C values increased from 0.03 per mil yr (super -1) in the 1960s to 0.095 per mil yr (super -1) in the 1990s, which was higher than expected due to solely the delta (super 13) C-Suess effect. Deeper water in this region exhibits higher concentrations of CO (sub 2) and low delta (super 13) C values. Transport of deeper water into surface water (i.e., upwelling) increases when the Aleutian Low is intensified. We hypothesized that the acceleration of the delta (super 13) C decline may result from increased upwelling from the 1960s to 1990s, which in turn was driven by increased intensity of the Aleutian Low. Detrended delta (super 13) C records also varied on 4-7 year and bidecadal timescales supporting an atmospheric teleconnection of tropical climate patterns to the northern North Pacific Ocean and Bering Sea manifested as changes in upwelling.

The clast consists of two lithologies: One is a quench-textured intergrowth of troilite with spottily zoned metallic Fe,Ni which forms a dendritic or cellular structure. The approximately 30 mu m spacings between the Fe,Ni arms yield an estimated cooling rate of this lithology of approximately 25-30 degrees C s (super -1) . The other is a quench-textured enstatite-forsterite-diopside-glass vitrophyre lithology. The composition of the clast suggests that it formed at an exceptionally high degree of partial melting, perhaps approaching complete melting, and that the melts from which the composite clast crystallized were quenched from a temperature of approximately 1380-1400 degrees C at a rate of approximately 25-30 degrees C s (super -1) . The association of the two lithologies in a composite clast allows, for the first time, an estimation of the cooling rate of a silicate vitrophyre in an aubrite of approximately 25-30 degrees C s (super -1) . While we cannot completely rule out an impact origin of the clast, we present what we consider is very strong evidence that this composite clast is one of the elusive pyroclasts produced during pyroclastic volcanism on the aubrite parent body (Wilson and Keil 1991). We further suggest that this clast was not ejected into space but retained on the aubrite parent body by virtue of the relatively large size of the clast of approximately 20 mm. Our modeling, taking into account the size of the clast, suggests that the aubrite parent body must have been between approximately 40 and 100 km in diameter, and that the melt from which the clast crystallized must have contained an estimated maximum range of allowed volatile mass fractions between approximately 500 and approximately 4500 ppm.

This finding was confirmed by all rover instruments, and a comprehensive study of these results is reported here. Spectra from the miniature thermal emission spectrometer and the Panoramic Camera reveal a pyroxene-rich mineralogy, which is also evident in Moessbauer spectra and in normative mineralogy derived from bulk chemistry measured by the alpha particle X-ray spectrometer. The correspondence of Bounce Rock's chemical composition with the composition of certain basaltic shergottites, especially Elephant Moraine (EET) 79001 lithology B and Queen Alexandra Range (QUE) 94201, is very close, with only Cl, Fe, and Ti exhibiting deviations. Chemical analyses further demonstrate characteristics typical of Mars such as the Fe/Mn ratio and P concentrations. Possible shock features support the idea that Bounce Rock was ejected from an impact crater, most likely in the Meridiani Planum region. Bopolu crater, 19.3 km in diameter, located 75 km to the southwest could be the source crater. To date, no other rocks of this composition have been encountered by any of the rovers on Mars. The finding of Bounce Rock by the Opportunity rover provides further direct evidence for an origin of basaltic shergottite meteorites from Mars.

Fused staghorn coral, A. prolifera, is an F1 hybrid with an intermediate morphology to the parental species. The hybrid is absent in the fossil record and has generally been documented as rarer than the parental species. Currently, however, hybrid abundance varies across geographic locations with some sites having equivalent or higher hybrid densities than at least one of the parental species. This apparent change in hybrid abundance may be a result of increased absolute hybrid abundance (i.e. hybrid embryo formation), increased relative abundance from increased asexual reproduction (i.e. fragmentation), or hybrids recently suffering less mortality than the parental species (i.e. hybrids lack the postzygotic barrier of inviability). Other studies have shown that prezygotic barriers are weak and many sampled hybrids have unique genotypes suggesting multiple distinct hybridization events. Here, postzygotic barriers of intrinsic and extrinsic inviability were examined across life history stages. Hybrids were not found to be inferior to the parental species at any examined life history stage, and in a few cases hybrid viability exceeded the parental species. Current evidence of weak reproductive isolation, an increase in the hybrid's relative abundance, and hybrid expansion into reef zones typically occupied by the parental species suggest that recent ecological changes in this system (i.e. dramatic declines in the parental species coupled with changes in the environment) may be affecting the frequency of hybridization.

Geographic variation in a species' engineering processes can thus have important implications for spatial heterogeneity in ecosystem function. In this study I explore geographic variability in the engineering properties of an important organism in marine ASHsedimentary habitats, the polychaete Diopatra cuprea. In the Northwest Atlantic, D. cuprea facilitates benthic communities by creating predation refugia and substrate-both density-dependent processes-and by actively attaching macroalgae to its tube. D. cuprea's ecosystem-engineering properties thus arise from both its abundance and its behavior. I show that both components of D. cuprea engineering decrease precipitously at low latitudes. I assess the relationship between these patterns and a suite of environmental parameters, finding that northern versus southern sites cluster separately in multivariate environmental space and that temperature, dissolved oxygen, and pH may contribute to both D. cuprea abundance and the biomass of facilitated algae. I present evidence that southern D. cuprea populations may be ASHaffected by post-recruitment mortality more severely than northern populations. Finally, I experimentally demonstrate that D. cuprea's failure to facilitate algae in its southASHern range is not due to latitudinal differences in algal availability, acceptability or retainASHability, but rather is a behavioral shift driven by still-unknown factors. This study demonstrates dramatic geographic variability in both D. cuprea's density-with strong implications for its density-dependent engineering functions-and D. cuprea's algal facilitation. Disentangling the mechanisms underlying such variability is an important goal for understanding spatial heterogeneity in the structure and function of NorthASHwest Atlantic shallow-water sedimentary systems.

Due to their low solubility, primary and authigenic HgS (e.g. cinnabar and metacinnabar) have historically been considered insignificant sources of soluble Hg(II) to the environment. Recently however, the solubility of HgS was shown to be greatly enhanced in the presence of a natural microbial consortium [1]. The mechanisms for this enhanced solubility have yet to be assessed. Moreover, bacteria and fungi capable of colonizing HgS surfaces in the environment have not been identified, yet their proximity and association with the mineral makes them likely key players in effecting chemical changes that can impact dissolution. To this end, we assessed the microbial diversity on HgS surfaces in the Hg-contaminated sediments and floodplain soils of the East Fork Poplar Creek in Oak Ridge, TN. Cinnabar and metacinnabar mineral sections were incubated at various depths, and hence redox conditions, in the creek channel, bank, and floodplain. Other metal sulfides, namely pyrite (FeS (sub 2) ) and sphalerite (ZnS), were also incubated to distinguish the host metal effects on the colonizing community composition. Composition and diversity were determined after 6 weeks of incubation, via pyrosequencing using bacterial (16S rRNA) and fungal (ITS) primers. Our results reveal a high diversity of microorganisms colonizing all the metal sulfide surfaces. The microbial community composition and phylogenetic diversity vary as a function of the host metal within the sulfide, as well as between the HgS polymophs, cinnabar and metacinnabar. Oxidation rinds are observed on metacinnabar surfaces, the extent of which decreases with depth within the sediment. These communities have been cultivated and are being investigated for their ability to solubilize HgS. The results from this study will have large implications on the role that microbial communities play in the dissolution of HgS phases and hence mobility of Hg within the environment.

My focus was the degree to which differences in canid ecology and social structure were correlated with differences in the plasticity of social and reproductive behavior, including development. Canid species are unusual among the Mammalia in being primarily monogamous. Males may play an indirect or direct role in parental care, depending on a species degree of sociality. Canid species also differ in developmental parameters, and reproductive suppression is common in the group-living pack hunters. I review comparative studies of the social and reproductive behavior of three South American canids which vary in their degree of sociality and explore the degree to which the species are ecologically and socially flexible.

This field guide focuses on examples near the town of Green River where there is public access to several different types of exhumed paleochannels within a small geographic region. We describe the geologic setting of these landforms based on previous work, discuss the relevance to analogous sinuous ridges that are interpreted to be inverted paleochannels on Mars, and present a detailed road log with descriptive stops in Emery County, Utah.

The regional distribution of fans points to a late period of widespread water-driven degradation.

Strong petrologic similarities between the pyroxenitic layer of a 120-m-thick, mafic Archean lava flow in Ontario, Canada, called Theo's Flow, and the nakhlite meteorite group may elucidate geologic processes that operated on Mars. Theo's Flow is in the Abitibi greenstone belt, an area that is well known as a komatiite location. The type locality, and best outcrop, of Theo's Flow is an upturned (approximately 70 degrees ) section stretching east-west for approximately 500 m. Theo's Flow can be divided into distinct lithologic units: a thin basal peridotite (0-9 m), a thick pyroxenite (50-60 m), a gabbro (35-40 m), and a hyaloclastic, brecciated top (8-10 m). It is the thick pyroxenitic layer that bears a striking textural similarity to the Martian nakhlites. Serpentinization of olivine, chloritization of orthopyroxene, and alteration (e.g., pseudomorphic replacement) of plagioclase and minor phases have transformed the original mineral assemblage, though augites remain largely unaltered, and textural relationships are well preserved throughout the flow. Variations in iron and minor-element abundances in augite cores exhibit typical trends for an evolving melt. Bulk rock analyses exhibit elemental trends consistent with an evolving melt, though they exhibit evidence of elemental remobilization by later metamorphism. An average of the peridotite, pyroxenite, and gabbro compositions compares well to that of the quenched top hyaloclastite, suggesting it is a single flow that was differentiated by crystal settling. The lithologic diversity within Theo's Flow suggests that nakhlites may also have complementary lithologies that remain unsampled.

During those periods, the island was colonized by large vertebrate predators that created selection pressure for large size and rapid growth in the snails. Extreme reduction in land area from rising seas, along with changes in ecological conditions at the onset of interglacial episodes, marked extinction events for large predators, after which snails reverted to much smaller size. The giant snails were identical in morphology during the last two glacials when the predators included a large flightless rail Rallus recessus (marine isotope stages (MIS) 4-2) and a crane Grus latipes and a duck Anas pachysceles (MIS 6). In a preceding glacial period (MIS 10), when the fauna also included the tortoise Hesperotestudo bermudae, the snails were not only large, but the shells were much thicker, presumably to prevent crushing by tortoises. Evolution of Poecilozonites provides an outstanding example of dramatic morphological change in response to environmental pressures in the absence of cladogenesis.

These five systems show transits from multiple exoplanet candidates. Should these objects prove to be planetary in nature, then these five systems open new opportunities for the field of exoplanets and provide new insights into the formation and dynamical evolution of planetary systems. We discuss the methods used to identify multiple transiting objects from the Kepler photometry as well as the false-positive rejection methods that have been applied to these data. One system shows transits from three distinct objects while the remaining four systems show transits from two objects. Three systems have planet candidates that are near mean motion commensurabilities-two near 2:1 and one just outside 5:2. We discuss the implications that multi-transiting systems have on the distribution of orbital inclinations in planetary systems, and hence their dynamical histories, as well as their likely masses and chemical compositions. A Monte Carlo study indicates that, with additional data, most of these systems should exhibit detectable transit timing variations (TTVs) due to gravitational interactions, though none are apparent in these data. We also discuss new challenges that arise in TTV analyses due to the presence of more than two planets in a system. Copyright (Copyright) 2010. The American Astronomical Society. All rights reserved.

Here, we compare two new devices for assessing density of woody debris, a spring penetrometer and a dynamic penetrometer, with the traditional decay classification and knife test in terms of the strength of the relationship with measured density and the consistency in measurements by four different people. Our evaluation was conducted in a diverse tropical forest and involved only a brief training period in each method. Classifications or scores from all four methods were only weakly correlated with measured density, and consistency among technicians in the measurement-density relationship was highest for the dynamic penetrometer. Therefore, we conclude that when training time is limited and the sampled logs can reasonably be assumed to be representative of all of the logs (e.g., an inventory of one site at one time), it is best to simply assume that the average density of the sampled logs is representative of nonsampled logs. For inventories involving multiple people, limited training, and cases where the sample average is likely to be unrepresentative, we recommend the dynamic penetrometer.Original Abstract: Les inventaires de necromasse des debris ligneux grossiers necessitent habituellement la mesure de la densite (p. ex. kilogrammes par metre cube) d'un echantillon de billes alors que la densite des autres billes est estimee en les repartissant dans des classes de decomposition. Dans cet article, nous comparons deux nouveaux appareils pour evaluer la densite des debris ligneux : un penetrometre a ressort et un penetrometre dynamique, avec le test traditionnel du couteau et l'utilisation de classes decomposition sur la base de la robustesse de la relation avec la densite mesuree et de l'uniformite des mesures prises par quatre personnes differentes. Notre evaluation a ete realisee dans une foret tropicale diverse et comportait seulement une breve periode de formation pour chaque methode. Les classements ou les resultats obtenus avec les quatre methodes etaient seulement faiblement correles avec la densite mesuree. L'uniformite de la relation entre les mesures des techniciens et la densite etait la plus elevee avec le penetrometre dynamique. Par consequent, nous concluons qu'il vaut mieux simplement assumer que la densite moyenne des billes echantillonnees est representative des billes non echantillonnees lorsque la duree de la formation est limitee et qu'on peut raisonnablement assumer que les billes echantillonnees sont representatives de toutes les billes (p. ex. dans le cas d'un inventaire effectue a un seul endroit et a un seul moment). Lorsqu'un inventaire implique plusieurs personnes, que la duree de la formation est limitee et dans les cas ou la moyenne des echantillons n'est probablement pas representative, nous recommandons d'utiliser le penetrometre dynamique.

Sixteen adult morphological characters were identified and scored for the six taxa currently recognized in this subgenus: Cicindela (Pancallia) angulicollis Horn 1900, C. (P.) aurofasciata Dejean 1831, C. (P.) goryi Chaudoir 1852 (new status), C. (P.) princeps ducalis Horn 1897, C. (P.) princeps princeps Vigors 1825, and C. (P.) shivah Parry 1848. Cladistic parsimony analysis of the resulting taxon-character matrix using the computer program NONA identified a single most parsimonious tree for these six taxa. Cicindela (Pancallia) angulicollis is the sister-species of the rare C. (P.) shivah, a species of current conservation interest in India. Cicindela (Pancallia) princeps is the sister-species of a monophyletic clade containing C. (P.) aurofasciata and C. (P.) goryi. Cicindela (Pancallia) goryi is restored to full species status based on differences in morphology, behavior, and ecological associations which separate this taxon from C. (P.) aurofasciata.

They were motivated in part by the broadening practice of accounting with the land, a modification of existing accounting practices, through which some farmers came to treat their relationship with the fields and animals of the farm landscape as a series of transactions between debtors and creditors. New forms of chemical analysis added a further dimension to this accounting, casting the growth of soil, animals, and plants and the exchange of materials between them as a series of transactions, and linking value in nutriment to value in money. Interactions between forms of food and monetary value on the nineteenth-century farm, as well as new forms of work that this interaction created, grew into a system of natural accounting. This system of valuation, emerging not from state power but from local engagement with individual farms and individual markets, continues to shape the industrial farm landscape.

This trade-off is maintained by inherent differences among species and spatial variation in light availability caused by canopy-opening disturbances. We evaluated conditions under which the trade-off is expressed and relationships with four key functional traits for 103 tree species from Barro Colorado Island, Panama. The trade-off is strongest for saplings for growth rates of the fastest growing individuals and mortality rates of the slowest growing individuals (r super(2) = 0.69), intermediate for saplings for average growth rates and overall mortality rates (r super(2) = 0.46), and much weaker for large trees (r super(2) less than or equal to 0.10). This parallels likely levels of spatial variation in light availability, which is greatest for fast- vs. slow-growing saplings and least for large trees with foliage in the forest canopy. Inherent attributes of species contributing to the trade-off include abilities to disperse, acquire resources, grow rapidly, and tolerate shade and other stresses. There is growing interest in the possibility that functional traits might provide insight into such ecological differences and a growing consensus that seed mass (SM), leaf mass per area (LMA), wood density (WD), and maximum height (H sub(max)) are key traits among forest trees. Seed mass, LMA, WD, and H sub(max) are predicted to be small for light-demanding species with rapid growth and mortality and large for shade-tolerant species with slow growth and mortality. Six of these trait-demographic rate predictions were realized for saplings; however, with the exception of WD, the relationships were weak (r super(2) 80% of the explained variation and, after WD was included, LMA and H sub(max) made insignificant contributions. Virtually the full range of values of SM, LMA, and H sub(max) occurred at all positions on the growth-mortality trade-off. Although WD provides a promising start, a successful trait-based ecology of tropical forest trees will require consideration of additional traits.

Hard-substratum benthic (biofouling) organisms, which dominate NIS richness, have arrived primarily as a result of shipping and aquaculture activity over past centuries. To date there has been no assessment of the leisure craft vector in the Bay. We aimed to characterize (1) biofouling on boats' submerged surfaces and (2) boater behavior likely to affect the risk of NIS transfers. We used an underwater pole-cam, specimen collections, and a boater questionnaire to quantify the extent and composition of biofouling on recreational boats and to evaluate boater behavior at a subset of the Bay's marinas. Several NIS, already established within the Bay, were recorded from vessel hulls, including the bryozoans Bugula neritina, Membranipora chesapeakensis and Watersipora sp., the ascidians Botrylloides violaceus, Styela clava and Ciona intestinalis, the polychaete Ficopomatus enigmaticus, and the sponge Clathria prolifera. Only 16% of questionnaire respondents had traveled to sites outside the Bay in the previous 12 mo. Frequency of hull painting and cleaning varied substantially, but we did not find strong patterns of biofouling extent associated with hull husbandry or boat usage. The potential for within-Bay and coastwise regional spread of NIS is high, and recreational boats probably interact in close proximity to other vectors (e.g. commercial ships), causing a ratchet effect of vector events; however, there remains a gap in understanding the levels and condition of biofouling on transient boats. Transient vessels from San Francisco Bay and other West Coast sites should be the focus of future studies to evaluate the extent to which organisms are being transferred among bays and how vector management could be applied to prevent NIS transfers and impacts.

Mutualism evolves most readily between members of different kingdoms, which pool complementary abilities for mutual benefit: some of these mutualisms represent major evolutionary innovations. Mutualism cannot persist if cheating annihilates its benefits. In long-term mutualisms, symbioses, at least one party associates with the other nearly all its life. Usually, a larger host harbours smaller symbionts. Cheating is restrained by vertical transmission, as in Buchnera; partner fidelity, as among bull-thorn acacias and protective ants; test-based choice of symbionts, as bobtail squid choose bioluminescent bacteria; or sanctioning nonperforming symbionts, as legumes punish nonperforming nitrogen-fixing bacteria. Mutualisms involving brief exchanges, as among plants and seed-dispersers, however, persist despite abundant cheating. Both symbioses and brief-exchange mutualisms have transformed whole ecosystems. These mutualisms may be steps towards ecosystems which, like Adam Smith's ideal economy, serve their members' common good.

Following a period of late Tertiary drainage from the Red Sea Hills south through Wadi Qena and west across the Tushka region, the Nile River as we now know it established its connections with Central Africa and the Mediterranean in the middle Pleistocene (oxygen isotope stage, OIS 7 to OIS 5). SRTM topography reveals a lake level at approximately 247 m that is coincident with the elevation of middle Pleistocene fish fossils 400 km west of the Nile, and with the termination of shallow runoff channels in northern Sudan that were active during the middle Pleistocene and Holocene pluvial periods. An additional lake level at approximately 190 m is based on the current elevation at Wadi Tushka, and is consistent with Paleolithic sites at Bir Kiseiba followed by Neolithic sites at lower topographic levels. Overflow of the Nile through Wadi Tushka during the wetter north African climate of the middle Pleistocene, coupled with limited local rainfall, was the likely source of water for these lakes.

Here we describe a cetacean thoracic vertebra from the late Miocene Tobabe Formation, a partial cetacean rib from the late Miocene Gatun Formation, and a sirenian caudal vertebra and rib fragments from the early Miocene Culebra Formation. These finds suggest that Central America may yet provide additional fossil marine mammal specimens that will help us to understand the evolution, and particularly the biogeography of these groups.

The late Quaternary of North America represents a natural experiment in which we can evaluate how species responded during the expansion and contraction of the glaciers. Here, we ask whether species' range shifts differ because of taxonomic affinity, life-history traits, body size or topographic heterogeneity and whether the species survived the megafaunal extinction. There was no difference in range shifts between victims and survivors of the megafaunal extinction. In general, the change in the size of a species' range is not well correlated with any of the ecological or life-history traits evaluated. However, there are significant relationships between some variables and the movements of the centroids of ranges. Differences in the distances shifted exist among orders, although this is probably a result of body size differences as larger bodied species show larger shifts. Although there are a few exceptions, the distance that species shifted their range was weakly correlated with life-history traits. Finally, species in more topographically heterogeneous areas show smaller shifts than species in less-diverse areas. Overall, these results indicate that when trying to predict species range shifts in the future, body size, lifespan and the topographic relief of the landscape should be taken into account.

Since its arrival in North America in 1999, West Nile virus (WNV) has led to population-wide declines of bird species, morbidity and mortality of humans, and expenditures of millions of dollars on treatment and control. To understand the environmental conditions that best explain and predict WNV prevalence, we employed recently developed spatial modeling techniques in a recognized WNV hotspot, Orange County, California. Our models explained 85-95% of the variation of WNV prevalence in mosquito vectors, and WNV presence in secondary human hosts. Prevalence in both vectors and humans was best explained by economic variables, specifically per capita income, and by anthropogenic characteristics of the environment, particularly human population and neglected swimming pool density. While previous studies have shown associations between anthropogenic change and pathogen presence, results show that poorer economic conditions may act as a direct surrogate for environmental characteristics related to WNV prevalence. Low-income areas may be associated with higher prevalence for a number of reasons, including variations in property upkeep, microhabitat conditions conducive to viral amplification in both vectors and hosts, host community composition, and human behavioral responses related to differences in education or political participation. Results emphasize the importance and utility of including economic variables in mapping spatial risk assessments of disease.

We investigated the tropical forest response to this rapid warming by evaluating the palynological record of three stratigraphic sections in eastern Colombia and western Venezuela. We observed a rapid and distinct increase in plant diversity and origination rates, with a set of new taxa, mostly angiosperms, added to the existing stock of low-diversity Paleocene flora. There is no evidence for enhanced aridity in the northern Neotropics. The tropical rainforest was able to persist under elevated temperatures and high levels of atmospheric carbon dioxide, in contrast to speculations that tropical ecosystems were severely compromised by heat stress.

AN - 873132672; 14711-1_0001 AB - PURPOSE: The construction and operation of the National Museum of African-American History and Culture (NMAAHC) between 14th and 15th streets and Constitution Avenue and Madison Drive in Northwest Washington, District of Columbia are proposed by the Smithsonian Institution. The project would provide a permanent facility on a five-acre parcel within the grounds of the Washington Monument. The Tier I final EIS for the project addressed potential effects of six massing alternatives that varied in siting and mass, orientation, form, exterior spaces, and profiles, as well as a No Build Alternative. The Tier I EIS process concluded with a Smithsonian Record of Decision in 2008 and a set of design principles to guide the development of specific concepts for the building that would permanently house the museum collection. Since November 2009, several different architectural concepts have been developed for the NMAAHC. This Tier II draft EIS analyzes four specific build alternatives, as well as a No Action Alternative under which the project site would continue be managed and maintained as parkland. The build alternatives each feature a Corona as the defining form of the visible building structure and the primary location for the galleries. Generally, four interior levels would be housed within the Corona and each alternative would feature two museum levels below grade. A primary entrance on the south side of the site would feature a hardscape plaza; service access and limited vehicular access would be provided from 14th Street. The building would incorporate several integrated strategies for sustainability, including: passive heating and cooling, day lighting, comprehensive stormwater management, and energy conservation. Alternative 1 would employ a plinth concept. The Corona would sit atop a plinth that accommodates a large ground floor program and frames the ground floor glass enclosure. Alternative 2 is based on a plaza concept and would divide the exhibit functions and administrative functions of NMAAHC into two distinct buildings on the site: the Corona and the northern building. The primary purpose of this alternative is to preserve views of the Washington Monument from the intersection of Constitution Avenue and 14th Street. Alternative 3, the pavilion concept, is similar to Alternative 1, but without the plinth. Alternative 4, the refined pavilion concept, is similar to Alternative 3, but would feature a Corona with reduced above-grade dimensions and would include entries on both the north and south sides of the site. The build alternatives would involve construction ranging from 294,000 gross square feet for Alternative 4 to 370,000 gross square feet for Alternative 2, and building heights of 108 feet to 121.5 feet above grade. POSITIVE IMPACTS: The museum would be dedicated to the collection, preservation, research, and exhibition of African-American historical and cultural materials, reflecting the breadth and depth of the experience of individuals of African descent living in the United States. It would constitute the only institution providing a national meeting place for Americans to learn about the history and culture of African-Americans and their contributions to and relationship with every aspect of our national life. Increased visitation to the District of Columbia due to the attraction of the museum would boost the local economy. NEGATIVE IMPACTS: The museum would displace an open space on the Washington Monument grounds of the National Mall, altering the historic boundaries of the grounds and altering the spatial organization of the grounds by diminishing the prominence of the Washington Monument as a central organizing feature. Significant impacts would also occur for buildings and structures located within the Monument grounds as well as the Federal Triangle along Constitution Avenue. Vegetation would be removed and the viewshed and specific vistas would be altered. The museum would be situated in an area in violation of federal standards regarding ozone and particulate matter.

Sediments yielding such "glassy" foraminiferal preservation tend to be found on passive margins, interior seaways and oceanic plateaus where burial depths were relatively shallow, fluxes of calcium carbonate were low and clay sedimentation rates were relatively high. Efforts to obtain oxygen isotope data from glassy foraminifera have met good success with studies of deep-sea and land-based sections from low, middle and high latitudes, resulting in a relatively complete paleotemperature history that spans nearly 50 m.y. from the late Aptian through the late Maastrichtian. These records reveal a long-term global climate cycle where the late Aptian-early Albian was relatively cool, the late Albian through the Cenomanian experienced long-term and gradual warming, the Turonian experienced extremely warm "Supergreenhouse" temperatures, the Coniacian-early Campanian continued with very warm temperatures, and the middle Campanian-late Maastrichtian experienced temperatures similar to those of the late Aptian-early Albian. Two major planktic foraminiferal extinction events occurred within this long-term climate cycle. The first occurs at the Aptian/Albian boundary where there is a dramatic reduction in planktic foraminiferal shell size, shell ornamentation, species diversity and standing population at the same time as abrupt shifts in oxygen, carbon and strontium isotopes. The cause of this extinction and associated geochemical shifts is not yet understood. The second planktic foraminiferal extinction event occurred just below the Cenomanian/Turonian boundary. Disappearance of only deep-dwelling species at the same time as abrupt bottom water warming suggests that this extinction was caused by greenhouse warming. A much denser array of sections yielding well preserved foraminiferal assemblages is needed to better understand these and other global climate changes, ocean geochemistry shifts and species turnover events that occurred during the Cretaceous.

The PCB collision is one of the most significant geological events in the Americas during the Cenozoic with important tectonic, climatic, geographic, and biologic repercussions at the regional and global scales. Tectonically, the collision of the PCB has been regarded as the engine of the major phase of uplift and deformation in the Andes of Colombia in the late Miocene-Pliocene. Although a cause-effect relationship between PCB collision and uplift of the Colombian Andes has been postulated, the chronology of the collision is still a matter of debate with ages ranging from approximately 27 to 4 Ma. During the last half-decade a significant amount of thermo-geochronological and stratigraphic data has been produced for the Central and Eastern Cordilleras of Colombia. This effort is now extended to include western Colombia and Panama with the aim of using areas proximal to the collisional zone to unravel the timing of collision and the morphotectonic response of the PCB. We present results of a low temperature thermochronology study (apatite and zircon (U-Th)/He and apatite fission-tracks) on approximately 40 samples collected along vertical profiles from Western Colombia and Panama. Significant UE phases (0.2-0.5 mm/yr) are found at ca. 47, 26, 14-11, and 5 Ma. Whereas the older Eocene event is probably a record of intra-oceanic tectonic stages in the PCB (seamount accretion or rebounding effects linked to crustal thickening by magmatic addition), the younger post-Oligocene events are consistent with Andean patterns and reflect the interaction with the South American margin and the final consolidation of the Isthmus. Special emphasis is given to the marked pulse of uplift and exhumation in the Colombian Andes and Panama at approximately 25 Ma. This event possesses synchronicity in the region and is related in space and time to a permanent shift in magmatic patterns in Panamanian arcs associated with extension during orocllinal development. We conclude that this strong pulse of uplift-exhumation marks the onset of collision of the PCB.

A virtually complete skeleton is exposed in right lateral view, with the slightly telescoped skull and several cervical vertebrae extending beyond the eggshell. A second, partial skeleton has a skull preserved in dorsal view. The embryos have proportionately very large skulls, with the broad skull table formed by wide parietals and frontals. The wide posterolateral wing of the frontal separates the postorbital from contact with the parietal. The embryos have short rather than elongated cervical vertebrae, with tall rather than low neural arches. The large forelimbs are only slightly shorter than the hind limbs, which suggests an obligatory quadrupedal posture for the hatchlings. This pattern may represent an ontogenetic constraint related to the large size of the head and horizontally oriented neck. Similarities between the embryonic and post-hatchling specimens include the slenderness of the lower jaw and slight ventral curvature of the symphyseal portion of the dentary, the large supraorbital process of the prefrontal, and the tall antorbital and infratemporal fenestrae. There are 10 cervical, 14 dorsal, and three sacral vertebrae. The large distal claw-bearing phalanx of manual digit 1 is longer than any other phalangeal element of either manus or pes. The embryos of Massospondylus carinatus represent the oldest dinosaurian embryos known to date.

Because SI is a tectonomagmatic singularity with no active examples, reconstructing SI is challenging. There is debate about whether SI requires compression as many geodynamicists suggest or can happen spontaneously, due to the excess density of old oceanic lithosphere alone. Studies of intra-oceanic forearcs provide clear and simple constraints for understanding SI, because forearc crust forms during SI and preserves a high-fidelity magmatic and stratigraphic record. We have heretofore been remarkably ignorant of this record, because the "naked forearcs" which expose SI crustal sections are distant from continents and lie in the deep trenches, making study and sampling expensive and difficult. Geophysical reflection and refraction studies cannot yet provide the level of detail needed, so samples of SI crust must be collected via "3D" dredging, diving, and drilling. Key advances in understanding forearc crustal structure were made as a result of DSDP Leg 60 and ODP Legs 125 and 126 expeditions to the Izu-Bonin-Mariana (IBM) forearc in the 1970's and 1980's; more forearc drilling is needed. Our studies of the IBM forearc (using Shinkai 6500) indicate that SI is accompanied by seafloor spreading in what ultimately became the forearc of the new convergent margin. IBM SI encompassed approximately 7 m.y. for the complete transition from initial seafloor spreading and eruption of voluminous MORB-like (fore-arc basalts, FAB) to normal arc volcanism, perhaps consistent with how long it might take for slowly subsiding lithosphere to sink approximately 100 km deep and for mantle motions to evolve from upwelling beneath the infant arc to downwelling beneath the magmatic front. Our best estimates are that FAB erupted at about 51-52 Ma, boninites began erupting around 48 Ma, and normal arc lavas began erupting around 44-45Ma, heralding establishment of a mature magmatic arc composed of discrete volcanic centers. The SI magmatic stratigraphy of the IBM forearc is seen in many SSZ ophiolites, consistent with the observation that most ophiolites are obducted forearc fragments. This understanding opens the door for on-land ophiolitologists to contribute fundamentally to understanding SI.

However, although the positions of Laurentia and Baltica are relatively well constrained, the role of Amazonia is still debated since few paleomagnetic poles are available and geochronological data from some key areas is scarce. A northward extension of the late Meso- to early Neoproterozoic collisional belt of the SW Amazon Craton, the Sunsas Belt, has been commonly inferred by the presence of high-grade metamorphic inliers included within the northern Andes of Colombia, but the reworked nature of these blocks with respect to the stable South American Platform casts doubts about their relation with the non-remobilized Precambrian crust that underlies the proximal foreland. We present the first geochronological evidence to support the existence of a Grenville-age orogenic segment buried underneath these basins. Altogether, more than approximately 1100 individual U-Pb ages in zircons from 18 samples of the cordilleran inliers, drilling-cores from the foreland basin basement and outcrops of the exposed stable shield, document the complex accretionary and collisional history that this margin underwent during the last stages of Rodinia assembly. Its evolution was characterized by mid to late Mesoproterozoic arc magmatism and arc-related sedimentation in a peri-Amazonian fringing-arc system, followed by arc accretion and metamorphism under amphibolite-facies conditions during the interval 1.07 to 1.01 Ga and final granulite-facies collisional metamorphism at ca. 0.99 Ga. This new geochronological evidence is inconsistent with collision against the Grenville Orogen of Laurentia, and instead supports correlations with the Sveconorwegian Province of Baltica and the central American Oaxaquian Terranes at the heart of Rodinia.

The higher the age resolution used for a collection, the more rapidly ages become outdated; and for long-term fossil collecting projects like the Panama Paleontology Project (PPP), consistent age assignments become increasingly problematic as collections grow. The PPP's program of collecting macro- and microfossils for paleobiologic research began in 1986, and all the collections will ultimately reside in large museums. The ages are based on planktic foraminifera and calcareous nannofossils using a global microfossil zonation and biochronology that has changed over 25 years through large time-scale revisions. Updates, enhancements, and calibrations of microfossil datums and zones in the International Committee on Stratigraphy (ICS) time scale occur too frequently for manual updates. Our project establishes a way to update ages of fossil collections in perpetuity, as follows: 1) Samples and sampling sites are stratigraphically ordered in meter-scaled sections. 2) Samples yielding age-diagnostic microfossils are identified as age-control levels. 3) Age conflicts and inconsistencies are resolved. (!) 4) Age ranges of the microfossils are entered in a file compatible with the ICS's TimeScale Creator (TSC, www.tscreator.org). 5) "Lookup" or reference tables in the PPP Database and TSC are linked to generate a set of age-limits for the microfossils comprising the age-control levels; a consistent minimum age-limit range is computed for assignment to a microfossil zone and geologic stage. 6) Ages and uncertainties of intervening samples are interpolated or extrapolated from the age-control levels and a "mean" age model for zone/stage boundaries is generated for the section. 7) The meter-scaled section and age-model section are displayed by TSC's visualization system; the age-model version allows testing facies trends among sections. 8) As ages change in the lookup tables or new microfossils are identified in samples, a new age model and set of graphics are recomputed for the section.

U-Pb dating of zircons and geochemical analyses imply different stages for the evolution of this belt, represented as an early suite of I-type subduction-related granitoids intruded between ca. 290 to 255 Ma, shortly followed by a more volumetric series of peraluminous S-type granites intruded within the age range from ca. 247 to 239 Ma. This last granitic event is coeval with mid- to high-grade metamorphism and anatexis recorded in para- and orthogneissic units, and is presumably related to the accretion of this terrane to the paleopacific proto-Andean margin. A minimum age for significant shearing and deformation is defined by the intrusion of undeformed granodioritic plutons at approximately 230 Ma, which crosscut the metamorphic foliation, generate localized metamorphic imprints, and reset regional muscovite Ar-Ar ages. This domain strongly differs from other Andean segments south of the Huancabamba deflection where both I- and A-type magmatism dominates. Therefore, we suggest that this oroclinal bend represents a major tectonic boundary that marks the transition between peri-Pangean accretionary orogens and internal Alleghanian-Ouachitan collisional belts.

Subduction of aseismic ridges or other anomalous oceanic elements (e.g. seamounts, spreading centers) have shown to cause major modifications in the uplifting, subsidence and magmatic patterns in the upper-plate from the trench towards extremely far inland. Preliminary provenance analyses of the Tumaco forearc basin (onshore segment) in the Pacific region of southwestern Colombia have delineated the major sources and their tracer compositional assemblages. The results have shown major shifts in detrital input, e.g., during the Miocene, an intermediate to felsic plutonic detrital source replaced the previous prominent volcano-sedimentary filling that characterized the basin. These provenance shifts are probably related to a major uplifting and exhumation phase of apparent deeper plutonic levels in the Western Cordillera that together with the associated structural segmentation record in the basin, are consequences of the subduction of some of the major aseismic ridges that characterized the Pacific margin of northern South America. Additionally, the younger record in the Tumaco Basin was strongly controlled by the growth and enlargement of the late Miocene to Pliocene magmatic arc in the Western Cordillera, which represents a renewed volcanic flux following the early Oligocene magmatism, and may be also controlled by the subduction of the anomalous Cenozoic features of the converging Nazca plate (e.g. Carnegie Ridge). Ongoing stratigraphic and biostratigraphic analyses, together with higher resolution provenance and thermochronological approaches will allow understanding the influence that subduction of variable features of the Nazca oceanic plate had along the northern South America Pacific margin and their time-process relations.

In the southeastern basin, the approximately 50 m thick PETM interval can be divided into three parts. The lowest interval is dominated by red and red-purple paleosols that are 1 m thick and strongly developed. Multiple paleosol proxies indicate that the floodplain became better drained at onset of the PETM. The driest or most seasonally dry conditions characterize the middle interval. Carbon isotope ratios show that the middle interval corresponds to the plateau phase of the carbon isotope excursion when temperatures were warmest. Paleosols in the upper interval, where isotopes become more positive again, show a return to wetter conditions. Changes in the degree of soil development through the section indicate that sediment supply was higher during deposition of the middle interval. Grain size analyses also show that floodplain deposits in the middle interval are coarser grained (< 40% clay) than floodplain deposits in the lower and upper intervals (clay percents commonly 60% or more). Thus, more rapid rates of sediment accumulation and coarser grain sizes correspond to a time of warmer temperatures and drier or more seasonally dry conditions. We hypothesize that the climatic conditions that characterized the middle interval caused reduced vegetation cover in the sediment source area and depositional basin. Reduction of vegetation, in turn, led to an increase in both the size and the quantity of sediment that was delivered to and transported by the fluvial system. In addition, greater seasonality of precipitation may have enhanced sediment yield and particle size. Other factors that can influence sediment supply and grain size--tectonic activity and source area lithology--are highly unlikely given the short time span ( approximately 10 (super 4) years) over which the sediment changed character. This study demonstrates how climate change can impact fluvial systems over relatively short time scales.

In spite of abundant outcrop and stratigraphic context, surprisingly little is known of the timing or ecological context of angiosperm radiation in western North America. Recent field work in the Cloverly Formation (Aptian-Albian) of northern Wyoming has revealed extensive deposits bearing plant megafossils at several levels. The time of deposition of the Cloverly is thought to correspond to the first major increase in eudicot diversity, and their spread from successional and disturbed habitats to a wider range of environments. Fourteen fossil plant sites identified from throughout the Cloverly Formation during the summer of 2010 should provide fresh evidence on the diversification and ecological spread of angiosperms. Sites near the base of the Cloverly contained only ferns and gymnosperms; sites near the top of the formation contained angiosperm leaves, which may be among the oldest records of the group in western North America.

A approximately 4m wide, mined contact between a jadeitite block and serpentinite melange matrix (Sierra de las Minas, Guatemala) consists of foliated albitite (cut by jadeitite veinlets) and meta-ultramafic rocks. Eleven samples were analyzed by XRF, ICP-MS, CL and SEM (Sorensen et al., 2010, International Geology Review 52: 899-940). Rare earth element (REE) data and new whole rock delta (super 18) O values redefine fluid sources and the scale of REE transfer. The delta (super 18) O values group by rock type: those of serpentinites and meta-ultramafic rocks are +7.8 to +8.5ppm; albitites, +12.8 to +13.2ppm; and jadeitites, +9.3 and +9.4ppm. The delta (super 18) O values of meta-ultramafic rocks are heavier than "typical mantle" of approximately +5.8ppm. Jadeitite delta (super 18) O values are heavier than jadeite data from Johnson & Harlow (1999, Geology) but range to ion microprobe values of jadeite (Sorensen et al., 2006, American Mineralogist). Albitite values are heavier than reported elsewhere, but resemble delta (super 18) O signatures of the low-T products of seawater-rock-sediment interaction. Guatemalan jadeitite and albitite are low-T rocks (e.g., Sorensen et al., 2006). Low-T-metamorphic seawater is a reasonable fluid source. Albitites contain poikiloblastic clinozoisite, titanite and zircon, all likely residence sites of REE. A jadeitite veinlet in albitite, sampled near the meta-ultramafic rock contact, displays approximately 2x block LREE values. The block is LREE-depleted (LaSm). The abundance and fractionation of REE in the veinlet could not be derived from the jadeitite block, albitite or ultramafic rocks, and requires m-scale REE transport along the contact. Jadeitite luminescence indicates fluids of varied compositions contributed to the block, whereas serpentinite-equilibrated (or derived?) fluid formed the veinlet (& albitite). Serpentinite (melange matrix) shows a large negative Ce-anomaly, suggesting low-T, rock-seawater interaction. Four of 5 albitite, both jadeitite, and one of 3 meta-ultramafic rock samples also display negative Ce-anomalies, again suggesting seawater. Albitite (retrogressed jadeitite) probably formed from subduction zone fluids with seawater-derived Ce-anomalies and a capacity for REE transport at m-scales.

However, the fact that these intrusive bodies (1) were emplaced close to the continental margin within an alloctonous oceanic metamorphic terrane (Santa Marta Belt), (2) are associated to short-term magmatism, and (3) are isolated from the main Andes, is hard to reconcile with models of subduction related arcs. New field work, geochemical and U-Pb age data allowed us to define the emplacement sequence, the cooling rates and to propose a petrogenetic model in relation to the Caribbean tectonics for these intrusives. An early event was identified at approximately 64 Ma, which is characterized by the emplacement of small volumes of trondhjemitic magmas. A later event, between 58 and 49 Ma, is represented by granodioritic to tonalitic rocks, with bodies of amphibole-rich cumulates and abundant mafic enclaves. Within this second event, ages of 56-55 Ma were obtained for the major part of the BSM and for the Latal Pluton, whereas the Buritaca and Toribio plutons yielded ages of 52-49 Ma. The early trondhjemitic magmatism can be related to partial melting of amphibolite facies rocks of oceanic affinity, similar to those exposed in the Santa Marta Belt. This event would mark the time when the Caribbean Plate collided with the South American Plate in the area. The second event is associated to flat subduction of the Caribbean Plate edge beneath the South American Plate under an abnormally high thermal regime, which resulted in intense dehydration, and possible melting, of the slab and may also have favored melting of the lower crust. The resulting hybrid magmas evolved by fractionated crystallization with significant amphibole segregation. Rapid cooling rates (80 degrees C/Ma), defined by zircon (U-Pb) and hornblende, biotite and K-feldspar (Ar-Ar) ages, are probably related to syn-tectonic intrusion during uplift of the SNSM, caused by underplating of the Caribbean Plate below South America. The composition of rocks and the short-lived magmatism indicates a punctual event related to the collision of the Caribbean Plate with the South American Plate, but not to the development of a magmatic arc associated to a well established subduction system.

Yet, both scientists and native communities share place, with geologists deriving the history of place through the study of rocks and indigenous communities embedding sense of place in their cultures and languages [2]. As a citizen of the Miami Tribe of Oklahoma, my work has focused on the Miami (myaamia), a Central Algonquian speaking people historically centered on the Wabash River in Indiana. Forced removal in 1846 to Kansas and subsequent removal to Oklahoma divided the community. After a century and a half of cultural and language loss, current revitalization efforts are reversing these trends. Together with Tribal linguists, cultural preservationists, artists, and engineers we have developed a multi-generational printed and web-based curriculum on Earth and Sky embedded within the culture of the myaamiaki to strengthen the sense of connection to place. Stories--particularly winter stories--are important in native communities. For our youngest citizens, we have three illustrated stories (ahkwaniswa neehi anikwa; peepicinehkia neehi ahsena; Twaawaahsamwa neehi kiilhswa) on concepts of awareness, Earth, and sky. We use myaamia for the main characters to encourage language use and provide online sound clips for pronunciation. Connection to place comes not from reading, but from experiencing your place. For school-aged children, we have 11 printed and web-supported activities, including exploring your place on foot, collecting rocks, exploring how the Sun marks direction and time, how the Moon marks the month and year, how ecological changes are recorded in our perception of time, to drawing and writing about your place. Places have overlapping histories, ranging from their formation long ago to the histories of the people who inhabit them today. For adults, we look at the geologic and cultural stories of 9 places in our homelands, ranging from how glaciers sculpted the rivers that became the traditional homeland of our people to how lead and zinc mines in Oklahoma continue to alter our lives.

The Rosales are a diverse group of flowering plants possessing a wide range of life history traits and dispersal modes, as well as a good fossil record. Here we quantify the relationships between different modes of dispersal, life history traits, and geographic range in rosalean genera using herbarium specimens and museum collection databases. We control for phylogenetic correlation using published phylogenies and gene sequence data from Genbank. Preliminary results from within the Rosaceae suggest a positive correlation between animal dispersal together with large propagules and increased geographic range and species diversity within genera, especially among woody taxa. There is also a positive correlation between number of continents occupied by a genus and the average proportion of those continents occupied. A positive correlation of geographic range size with animal dispersal is consistent with patterns seen in conifers. However, that the association is stronger in woody Rosalean genera suggests that life history traits may affect the relationship between between dispersal mode, biogeography, and biodiversity. Because long-lived woody plants would have fewer generations between Milankovitch or sub-Milankovitch scale climate events than short-lived herbs, we would predict that effective long-range animal-mediated dispersal would be more favored in woody taxa than in herbs. We plan to test this in two ways: first, by examining range-dispersal relationships in long-lived perennial herbs, and second, by examining changes in relative frequencies of animal-dispersed woody taxa in the past when glacial-interglacial climate cycles characteristic of the Quaternary were presumably less severe.

Leaf physiognomy, reconstructed paleoclimate, intensive insect herbivory, and the floristic composition of the floras suggest widespread rainforests during the Paleocene in Colombia. These ancient rainforests exhibit the typical elements of the canopy, understory, and shrub/liana layers found in extant tropical rainforests. The most common and abundant families/orders identified so far include: Anacardiaceae, Annonaceae, Araceae, Arecaceae, Euphorbiaceae, Fabaceae, Icacinaceae, Lauraceae, Malpighiaceae, Malvaceae, Meliaceae, Menispermaceae, Salicaceae, Sapotaceae, Zingeberales, Violaceae, six species of ferns, a cycad, and a conifer, among others. The fruit and seed morphological diversity includes a wide range of sizes and dispersal mechanisms, such as winged taxa, legume pods, and endocarps associated with fleshy fruits. These new paleofloras from northern South America provide a new insight into the early Cenozoic evolution of Neotropical floras, and suggest that these rainforests were composed of a mixture of various biogeographical elements. These include angiosperm families and/or genera endemic to modern Neotropics and taxa currently restricted to the Paleotropics. In contrast, the ferns had more affinity with paleofloras from the Paleocene of North America.

The late Quaternary of North America represents a natural experiment in which we can evaluate how species responded during the expansion and contraction of the glaciers. Here, we ask whether species' range shifts differ because of taxonomic affinity, life history traits, body size, topographic heterogeneity, and whether the species survived the megafaunal extinction. There was no difference in range shifts between victims and survivors of the megafaunal extinction. In general, the change in the size of a species' range is not well correlated with any of the ecological or life history traits evaluated. However, there are significant relationships between some variables and the movements of the centroids of ranges. Differences in the distances shifted exist among orders, although this is likely a result of body size differences as larger-bodied species show larger shifts. Although there are a few exceptions, the distance that species shifted their range was weakly correlated with life history traits. Finally, species in more topographically heterogeneous areas show smaller shifts than species in less diverse areas. Overall, these results indicate that when trying to predict species range shifts in the future, body size, life span, and the topographic relief of the landscape should be taken into account.

The dunes are dominated by mainly quartz-rich sands of the ancestral Colorado River that mix with locally-sourced, feldspar-rich sands from the surrounding alluvial fans of the Basin and Range Province and the Sonoyta River. However, more detailed analysis is required to understand sediment sources and transport pathways. The scanning electron microscope (SEM) with an energy dispersive spectrometer (EDS), especially under the control of a computer (CCSEM), can be deployed in a particle-by-particle or point count mode to characterize thousands of particles per sample. Because a particle observed in the backscattered electron imaging mode has a brightness proportional to its average atomic number, the analysis can be set up to characterize all particles, or only the bright accessory minerals. In the point count mode, the electron beam dwells at point locations on a grid and characteristic x-rays are emitted. The EDS spectrum is acquired and the mineral phase is interpreted. An SEM image and EDS spectrum are saved for possible further review. In the particle-by-particle mode, the particle periphery is also detected and physical measures such as size and morphology can be derived. The analytical methods of CCSEM, including advantages and disadvantages, will be described and illustrated using examples of inland dune sands from the Gran Desierto. The combination of the TIR remote sensing and the SEM intimate sensing, each yielding complementary information, can be used to provide a more complete understanding of sediment sources and processes in this environment.

The Sierra Pinacate volcanic complex, dominated by basalts, lies to the east of the main dune field. The center of the Gran Desierto overlies thick sequences of fluvial-deltaic sediments associated with the ancestral Colorado River. There are groups of dunes hypothesized to be genetically different eolian accumulations of different age and composition. Therefore, a number of possible local- to regional-scale sand transport pathways exist for sources of sand to the dunes. Determination of the surface mineral composition was accomplished using thermal infrared (TIR) remote sensing data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument. Because the mixing of emitted radiant energy is linearly related to the areal abundance of major dune forming minerals that have diagnostic spectral absorption features, the mineralogical composition was extracted using spectral linear deconvolution of the TIR emission spectra from both remote sensing and laboratory spectroscopy. TIR remote-sensing data were from a seamless, multispectral, radiometrically balanced image mosaic from the ASTER instrument. The laboratory analysis of eolian sand samples using high resolution thermal emission spectroscopy were used to validate remote sensing data. The major spectral end-members of the samples were determined, reported here in decreasing order of areal abundance: quartz > plagioclase feldspar > potassium feldspar > carbonate > ferrohornblende. Spatial patterns of bulk mineral composition revealed the eolian sediment mixing dynamics and sediment transport pathways. The interpolated laboratory data provided hyperspectral resolution at specific sampling points, which compared well to the retrievals of sand composition from ASTER data. The majority of the sand in the Gran Desierto can be described by a two-source sediment mixing model, revealed by the spatial gradients between quartz-rich Colorado River source material and feldspar-rich local source material supplied by the Basin and Range and the Sonoyta River.

Processing of the Shuttle Radar Topography Mission (SRTM) data at the available 90 m (spatial) resolution reveals details that tie together several disparate lines of evidence for large-scale, mid-Pleistocene lakes. At Bir Tarfawi, 400 km west of the Nile, fossil fish of the last interglacial occur at the same elevation as the termination of shallow surface runoff channels north of Selima Oasis in Sudan. Stepwise infilling of the present topography suggests an extensive lake at an elevation of approximately 240 m that accounts for both features. This lake extended more than 300 km south to north from the Sudan border to Kharga Oasis in central Egypt, and covered an area of 68,000 km (super 2) . A lower lake level at approximately 190 m coincides with the elevation of the connection with the Nile through Wadi Tushka, and with the transition from topographically higher Paleolithic sites to lower Neolithic sites in the Kiseiba Oasis region. The timing of these mid- to late Pleistocene lakes coincides with the change in drainage direction of southern Egypt. From late Tertiary to mid Pleistocene, drainage from the Eastern Desert was to the south through Wadi Qena and west across the Kiseiba-Tushka Depression. In addition to the Shuttle radar-detected channels, an isolated meander bend on the south edge of the limestone plateau west of the Nile may be a relict of this drainage. We believe that the African connection and northward drainage of the Nile began in mid Pleistocene, perhaps aided by overflow of extensive lakes in Sudan across the Nubian swell. Although local precipitation was greater in the mid Pleistocene ( approximately 500 mm/yr), the overflow from annual Nile flooding following establishment of northward Nile drainage seems a more likely source for the Egyptian lakes.

This study presents the results of whole-rock geochemical analyses of altered lacustrine sediment in the Pleistocene Olorgesailie Formation, Kenya, within paleosols of Member 1 (UM1p) and Member 7 (UM7p). Based on Ar/Ar dates these are constrained to approximately 0.99-0.97 and approximately 0.90-0.78 Ma in age, respectively. Several major oxides and ratios provide useful indicators of paleoenvironmental processes. For example, SiO (sub 2) in these units ranges from 62-83 weight%, and TiO (sub 2) ranges from 0.4-1.7 weight%. These two indicators are strongly inversely related (e.g. UM1p: r (super 2) =0.84, p<0.0001), reflecting the competing geochemical signals of diatom productivity and preservation versus detrital input. Samples of UM1p laterally distributed over approximately 3km of the basin have lowest SiO (sub 2) /TiO (sub 2) ratios to the west, suggesting a detrital source in that direction. In contrast, UM7p SiO (sub 2) /TiO (sub 2) ratios are less variable across the field area, consistent with observations of more uniform primary lithology in the unit. Elemental ratios such as Ba/Sr and (Fe (sub 2) O (sub 3) +MnO)/TiO (sub 2) provide data on variability in post-depositional paleo-hydrolytic or paleo-oxidative conditions, respectively. Significant relationships are also found between these indicators of diagenesis (e.g. UM1p: r (super 2) =0.45, p<0.001). Both UM1p and UM7p have higher Ba/Sr and (Fe (sub 2) O (sub 3) +MnO)/TiO (sub 2) to the east, suggesting greater weathering in that direction at times of subaerial exposure. Weathering indicators are overall more severe in UM7p, consistent with its interpreted longer period of exposure and pedogenesis. These diagenetic and pedogenic conditions are of particular interest for paleoenvironmental studies focused on terrestrial flora, fauna, or hominin paleoecology, as they reflect conditions during low lake level and subaerial exposure. Lateral variability of primary and diagenetic geochemical signatures is important to consider in the interpretation of data from sediment cores, serving to remind us of the importance of sedimentary facies models to contextualize geochemical data.

Central Africa is a major source for columbite-tantalite, which is included in the suite of "conflict minerals" whose illicit export is considered responsible for financing the ongoing civil conflicts in this region. With the passing into US law of the financial reform bill of 2010 (S.3217-Restoring American Financial Stability Act of 2010), US companies will soon be required to report annually to the Securities and Exchange Commission about whether their products contain gold, tin, tungsten, and tantalum from the Democratic Republic of Congo or adjacent countries. Thus, being able to recognize the "conflict minerals" that are the source for these elements has taken on increased urgency. Laser-induced breakdown spectroscopy (LIBS) may be a convenient and low-cost means for rapidly determining a mineral's geographic origin because the LIBS plasma emission spectrum provides a "chemical fingerprint" of any material in real-time. Toward this end, five sets of columbite-tantalite samples from spodumene-bearing granite pegmatites in Maine, California, and the Northwest Territories of Canada have been analyzed. Individual spectral emission lines and line ratios for Fe, Mn, Nb, Ta, W, Ti, Sc, Sn, and Zr were measured using an RT100-HP LIBS instrument (A3 Technologies LLC/Applied Spectra, Inc.) employing a 90mJ, 1064 Nd:YAG laser and CCD detector. Both broadband (250-490 nm) and narrowband (240-280 nm and 315-355 nm) spectra were used to determine if the provenance of the samples could be discriminated using advanced multivariate statistical techniques. Partial Least Squares Discriminant Analysis (PLS-DA) gave 100% sample-level classification using a highest confidence approach. These promising preliminary results suggest that additional work with a larger, more geographically diverse data set that includes samples from the major production areas in Australia, Brazil, China, Ethiopia, and Mozambique is warranted.

The shell geochemistry of calcitic microfossils, particularly Mg/Ca ratios, is increasingly used in such studies as paleothermometers. Although shell chemistry of planktonic and benthic foraminifera have received substantial attention, marine ostracodes have several distinct advantages for BWT reconstruction: long stratigraphic ranges for well-studied genera (Krithe, Loxonconcha: Cretaceous-Recent), growth by molting (no ontogenic variability with adult shell analyses), large heavily calcified shells (0.3-1.0 mm; 10-100 mu g), and high Mg/Ca concentrations over wide temperature ranges (Loxoconcha 10-26 degrees C, 20-50 mmol/mol; Krithe: -1.5 to 14 degrees C, 5 to 25 mmol/mol). In addition, some deep-sea species of Krithe may live infaunally ( approximately 1 to 10 mm), reducing the influence of carbonate saturation state that complicates deep benthic epifaunal foraminifera like Cibicidoides. We will present Mg/Ca records from the Pliocene-Quaternary of the North Atlantic, the last 50 ka from the Arctic, and the Holocene of Chesapeake Bay and focus on issues of past and current climatic warming and ocean circulation.

In this presentation, I review how marine benthic ecosystems have responded to climate and human-induced environmental changes using ostracods and foraminifera. In deep sea ecosystems, species diversity and faunal composition show large-amplitude changes during the Pliocene and Quaternary, especially in tropical latitudes, that correlate with 41 and 100 ka Milankovitch cycles. These dynamic faunal changes indicate pervasive patterns of changing latitudinal species diversity gradients over orbital time scales such that the latitudinal diversity gradient was weakened or absent during glacial periods. Over suborbital time-scales, benthic faunal collapses in the deep sea were triggered by oceanographic changes during abrupt cooling events such as the Younger Dryas and other deglacial and Holocene stadials. During the last few centuries, the footprints of human activity have increased especially in coastal shallow-marine areas where industrialization and land-use changes have triggered rapid ecosystem degradation that continue today. I will discuss case studies illustrating processes of the human-induced ecosystem degradation from micropaleontological perspective, which provide insights into the timing, regional differences/commonality, and faunal structure during these disruptions.

Mini-RF is capable of imaging in two bands, X-band (4.2-cm) and S-band (12.6-cm), at 150 m and 30 m (Zoom Mode) resolution respectively, and with an illumination incidence angle of approximately 48 degrees . The majority of its observations to date have been obtained in S-Band Zoom Mode. Mini-RF was designed to map the permanently dark areas of the lunar poles and characterize the nature of the deposits. In addition, to aid global analyses of mare composition, Mini-RF has acquired coverage for most of the maria. Mini-RF observations of geologic targets of interest are used to improve TiO (sub 2) mapping within the lunar maria. Targets of interest include basalt flows that were estimated to contain high-TiO (sub 2) compositions based on Clementine spectral reflectance data but had low-TiO (sub 2) compositions as measured by Lunar Prospector neutron spectrometer data (LPNS). Visible and near infrared spectral characteristics of lunar soils are controlled by multiple competing factors. Ilmenite, the principal oxide phase, is dark and spectrally neutral relative to the spectrally red mature lunar mare soils; thus causing soils to become spectrally bluer as ilmenite content increases. However, large uncertainties in ultraviolet-visible (UVVIS) based estimates of TiO (sub 2) are revealed when comparing LPNS TiO (sub 2) and Clementine UVVIS 415/750 ratio. Prime culprits identified as causing this effect are differential agglutinate formation on high-FeO flows, TiO (sub 2) in phases other than ilmenite, and surface contamination by highlands materials. Similar to UVVIS spectra, depolarized radar return is found to anticorrelate with titanium abundance--with higher TiO (sub 2) abundance leading to lower radar returns. The source of the titanium affecting the radar return is thought to be ilmenite. The possibility that the radar loss tangent is modulated by other mineralogic components is unsupported. Therefore, differences between TiO (sub 2) or FeO in silicates, which darkens them so they act opaque, and TiO (sub 2) in ilmenite can be determined. Integrating complimentary information from these independent data sets yields encouraging results explaining observed differences between UVVIS spectral based maps of TiO (sub 2) and LPNS TiO (sub 2) .

Though sinuous rille formation has been attributed to thermal erosion of the substrate by turbulent flow of low-viscosity lava, for those originating in highland sites, the influence of the different substrate material, pre-existing topography, and structural controls on the emplacement and morphology must be considered. Here, we focus on the morphology of three rilles using high resolution images (0.5 m/pixel) from the Lunar Reconnaissance Orbiter Camera (LROC) and topographic data from the Lunar Orbiter Laser Altimeter (LOLA). Vallis Schroeteri originates on Aristarchus Plateau, a topographic high comprised of a complex stratigraphy of units interpreted to be anorthositic and/or granitic, basaltic, pyroclastic, and impact. The path of the 155-km long primary rille (<10 km across) is influenced by pre-existing topography. Apparent layering in outcrops observed in LROC images in both upper wall of the primary rille and the inner rille are potentially related to lava flows. Volcanic mounds on the Cobra Head and a flow margin at the end of the primary rille are also observed. The 140-km long Rimae Plato III originates along a fault scarp near the crater rim and has a broad primary rille ( approximately 3 km across) with a flat, lava-filled floor and inner rille ( approximately 500 m across) that does not exhibit tight meanders. The walls of the primary rille grade out towards the base of the ejecta blanket, influenced by the thickness of the deposit. LROC images show enigmatic low albedo material associated with higher albedo rock exposures along the upper wall of the primary rille and potentially layered units in the inner rille wall related to the lava flows. LROC also provides details of a potential overflow deposit from the inner rille that occurs in Mare Imbrium. Vallis Alpes is a 150-km long rille confined down the center of a narrow, lava-filled valley that stretches from the rim of the Imbrium Basin to Mare Frigoris. No distinct vent is visible, but LROC images show a remnant lava pond, breached dam, and an island confined between mountainous terrain. LRO data are being used to constrain dimensions, morphology, and geologic context to interpret the emplacement of these unique rilles.

Phyletic gradualism considers living fossils as prime examples of bradytely, or unusually slow rates of evolution. Alternatively, the punctuational model proposes that evolution primarily occurs through speciation and that living fossils are simply long-lived taxa which escaped extinction. Consistently low diversities over great intervals imply sluggish speciation and therefore conserved morphologies (the so-called "test of living fossils"). Assuming that taxonomic diversification is correlated with morphologic evolution, an examination of large-scale patterns of generic (or ideally, species) diversity may provide a rough approximation of the rate of morphologic change. Analysis of the geologic histories of living fossil taxa at the generic level reveals four major patterns. 1) Rapid diversification associated with initial adaptive radiation, an abrupt decline in speciation, and a subsequent period of low diversity lasting hundreds of millions of years characterize the lungfishes, lingulid brachiopods, and monoplacophoran mollusks. 2) A similar pattern may be found in the Aplodontidae (mountain beavers) and tapirs, except the extended phase of low diversity is not present because these mammalian groups originated relatively recently in the Cenozoic Era. 3) Generally high diversity early in a clade's history followed by repeated episodes of radiation and extinction results in a jagged diversity curve; horseshoe crabs, coelacanths, rhynchocephalian reptiles, nautilid cephalopod mollusks, and perhaps the sclerosponges exhibit this pattern. 4) Both mytilid and pinnid bivalve mollusks show an unexpected pattern of increasing diversity through time--contrary to the usual view of living fossils as the sole remnants of once diverse clades. These results suggest that living fossils do not share a common evolutionary pattern and offer predictions on the actual rate and magnitude of morphologic evolution in these taxa.

The evolution of the northern Andes has fragmented the basin, creating many structural complexities and stratigraphic asymmetry related to syntectonic deposition. The Middle Magdalena Valley basin located between the Central and Eastern Cordilleras is one of the products of this fragmentation. The alluvial plain rock sequence of the Esmeraldas Formation is an important reservoir in the basin. Because of the complex and continental nature of the basin, the lateral continuity of the Esmeraldas is not clearly understood. Additionally, there are very few reliable correlation elements. The Los Corros fossil horizon, a mollusk horizon in the upper part, is the most traditional correlation component used to differentiate the Esmeraldas. This is the only paleontological unit formally associated with the Esmeraldas. This horizon, however, is not continuous over the entire basin and its age is still debatable, introducing uncertainty to existing stratigraphic models. Furthermore, the uncertainty in the age of the Esmeraldas makes temporal correlations of this Formation with units in adjacent basins unclear. Palynology appears to be the best paleontological tool for correlation in the basin. Data from an outcrop section and seven wells have been integrated with a palynostratigraphical zonation previously proposed for northern South America in order to obtain the age for the Esmeraldas Formation. We infer that the lower part of the Formation has a Middle Eocene age, mainly based on the First Appearance Datum (FAD) of Rhoipites guianensis and Cicatricosisporites dorogensis. The upper part (including the Los Corros) is late Eocene, based on the Last Appearance Datum (LAD) of Racemonocolpites facilis and the presence of Luminidites colombianensis. The palynostratigraphy of the unit will serve as a reference for accurate subsurface correlations in the basin. It also will be useful when integrated with non-paleontological tools to better constrain the lateral extent of the Esmeraldas and its relationship with lithostratigraphic units in adjacent basins in Colombia. In addition, the age of the Esmeraldas will contribute to a better understanding of the overall evolution of the basin.

However the proposed phylogenetic hypotheses and biostratigraphic inferences have not been tested in more than one stratigraphic section and taxonomic distinctions have not been established based on biometric comparison of species populations. We present a biostratigraphic and biometric study of remarkably well preserved late Cenomanian-early Santonian biserial planktic foraminifera recovered from a series of boreholes drilled during the Tanzania Drilling Project. In this study we combine detailed SEM observations with measurements obtained from high-resolution x-ray images using primary type specimens (where possible) and populations from multiple stratigraphic levels in order to more reliably (1) haracterize intraspecies variability, (2) delineate interspecies differences, and (3) test the new phylogenetic hypotheses. The x-ray images provide the best means of discriminating chamber outlines for the entire ontogenetic growth trajectory in well preserved biserial tests and they enable rapid collection of a wide array of shape and size measurements. We provide comparative biometric data for populations of Heterohelix globulosa (Ehrenberg), Hx. reussi (Cushman), Globoheterohelix paraglobulosa Georgescu and Huber, Planoheterohelix moremani (Cushman), Pl. postmoremani Georgescu and Huber, Huberella praehuberi Georgescu, and Hu. huberi Georgescu. We demonstrate that (1) Pa. paraglobulosa and Hx. globulosa show distinct differences in their ontogenetic growth profiles, (2) Hx. reussi and Hx. globulosa are indistinguishable, (3) Pl. moremani and Pl. postmoremani are indistinguishable, and (4) the evolutionary transition from Hu. praehuberi to Hu. huberi consistently occurs in the late Turonian and is marked by easily recognizable changes in the external test morphology. Our approach of using SEM observations and measurements together with biometric data obtained from X-ray images enables development of a more reliable taxonomic framework for comparison of biserial planktic foraminiferal species populations.

Integrated teams of engineers and scientists have merged exploration technologies with exploration strategies to support these ambitious field tests. The centerpiece of these tests over the past three years has been a prototype planetary rover called the Space Exploration Vehicle (SEV). The SEV has supported near-autonomous operations of a pair of astronauts on simulated planetary missions for up to two weeks. During such traverses, investigations can be conducted from within the pressurized environment of the cabin using a suite of cameras and other sensors. The crew can also conduct extravehicular activities (EVAs) facilitated by the innovative "suitport" hatches that allow quick egress and ingress, greatly increasing the flexibility of EVAs while enabling the crew to quickly recover in the shirtsleeve environment of the SEV. The results of the 2009 D-RATS field test at Black Point Lava Flow (BPLF), AZ: 1) highlighted the critical role of having at least one professional geologist per SEV crew and their bearing on achieving the scientific goals of the mission; 2) pointed out the challenges and opportunities in developing a well-trained geological science support team and procedures for field operations, data analysis and curation; and 3) served as an important test of methodologies for constructing, executing, and modifying traverse/EVA plans, in modalities where reconnaissance data is or is not available and when communications are continuous or intermittent. The recent (8/31-9/13/2010) D-RATS field campaign at BPLF and SP Mountain, AZ involved, for the first time, simultaneous operations of two SEVs, each crewed by a geologist and a professional astronaut. The D-RATS team investigated the best practices for effective science team-crew operations using two communication modes with mission control. The results of the 2010 tests further emphasize the vital role that professional field geologists will play in crewed planetary science missions, including: 1) traverse planning; 2) development of field and operational protocols; 3) crew training; 4) science support operations; 5) and, most importantly, as crewmembers during planetary surface operations.

A branching model of cladogenesis incorporating empirical rates of fossil preservation was consequently used to estimate the true durations of marine animal orders. Marine ordinal diversity through geologic time is consistent with the logistic model of population growth, exhibiting a rapid exponential increase in the number of orders during early Paleozoic time followed by approximately constant diversity over the next five hundred million years. Goodness-of-fit between observed and corrected ordinal diversity is remarkably high at the 50% confidence level (r (super 2) = 0.966), with only minor deterioration at the 95% confidence level (r (super 2) = 0.900). Each of these orders can be assigned into the great evolutionary faunas, aggregations of classes that reached maximum diversity at similar times and have successively dominated the marine fossil record. Analysis of the Cambrian Fauna at the 50% confidence level (r (super 2) = 0.980) indicates higher early ordinal diversity in the corrected curve, probably reflecting both genuine range extensions and poor stratigraphic constraints. The Paleozoic Fauna (r (super 2) = 0.966) radiated rapidly, stabilizing in mid-Paleozoic time with over forty orders followed by a steady four hundred million year post-Devonian decline. Unlike the patterns in families and genera, no massive drop in ordinal diversity is seen during the terminal Permian mass extinction. Slow expansion characterizes the Modern Fauna (r (super 2) = 0.993), which achieved maximum diversity in the late Mesozoic Era with over seventy orders and declined slightly thereafter in Cenozoic time. A smaller sample consisting of bivalve and gastropod mollusks also shows a strong correlation (r (super 2) = 0.984) between observed and corrected curves, indicating that the fidelity of the fossil record extends to the diversity histories of well-skeletonized invertebrate classes. These results therefore suggest that the fossil record largely preserves the shape of marine diversity at the ordinal level.

Recent studies have provided support for an ignimbrite origin for MFF, but alternative origins have not yet been totally eliminated. At the 2009 GSA meeting, we reported on recent mapping efforts that reveal evidence that MFF was previously much more areally extensive than is inferred from the boundaries identified through Viking-based geologic mapping. The release of version 11 of the Thermal Emission and Imaging System (THEMIS) global mosaics provides an improved base on which to map out possible outliers of MFF materials. Here we present results from recent mapping of MFF outliers on the new THEMIS daytime infrared mosaic, which has a 100 m spatial resolution posting, supported by evidence of thermophysical variations between layers exposed within the eroded outlier deposits inferred from the co-registered THEMIS nighttime infrared mosaic. New mapping within the MC-23 NW quadrangle of Mars indicates that isolated outliers of MFF, identified during the work reported last year, now appear to be connected, resulting in considerable expansion of the area potentially covered by previous MFF deposits that have subsequently undergone intense aeolian erosion and degradation. The increased area that may have been covered by MFF has important implications for the ignimbrite origin of MFF, particularly with regard to the original volume of the deposits. If MFF is the result of large ignimbrite eruptions, the increased total volume of the deposits implies that the equivalent of 1000 Toba-sized eruptions (the largest explosive eruption identified from terrestrial deposits) would be required to generate the MFF materials.

Refractory minerals that formed during the violent deaths of other stars and during condensation of our own solar nebula mixed with a wide range of silicates, sulfides, and metals to form the most primitive chondritic meteorites. Subsequent aqueous alteration, thermal metamorphism, and shock metamorphism further diversified the minerals found in meteorites. Asteroidal melting at first increased and then dramatically decreased mineralogical diversity, before a new phase of igneous differentiation that presaged the processes that would occur in terrestrial planets.

This vast area of tropical Euramerica records a sharp floristic turnover in wetland environments--coal beds, mineral soil coastal plains and floodplains. This turnover, occurring within a single glacial-interglacial cycle, resulted in a marked change in species composition and dominance-diversity patterns, and restructuring of wetland vegetational architecture. At the same time, vegetation of more seasonally dry regions in western Pangea, dominated by xeromorphic seed plants, appears to have been little affected by this event. In central New Mexico, a succession of paleofloras dominated by conifers, seed ferns, and callipterids occurs through a mixed marine-nonmarine section encompassing the Desmoinesian-Missourian boundary (age control by conodonts). These floras occur contemporaneously with the wetland vegetation of the central Pangean tropics. The different patterns in these areas suggest that distinct biomes may have very different "internal" responses to global warming, varying from minimal to catastrophic. Examination of the late Moscovian-through-Gzhelian indicates that xeromorphic floras of seasonally dry climates, occupants of diverse habitats, oscillated spatially across central and western Pangea during cyclic changes in ice-age climate. In contrast, the edaphically narrow wetland biome appears to have been unable to migrate widely due to physical habitat and climatic constraints and, instead, contracted into regional refugia during drier climatic phases.

We present results of an ongoing study in which we focus on the paleoceanographic and paleoclimatic history at low latitudes during the Turonian period of global warmth. The studied material contains abundant and well diversified foraminifera faunas indicating an outer shelf to upper slope position. Consistently present calcareous species are used for carbon and oxygen isotope measurements. To enhance our understanding of the stable isotope data we study intra-species offsets and their relation to carbonate geochemistry of the shells, by applying a combination of light-microscope and SEM imaging with microprobe and cathodoluminescence-based geochemical analyses. For example, various aragonitic-shelled species of the genus Epistomina show a striking offset in carbon isotopes while displaying similar values in oxygen isotopes, as compared to other benthic species. Cross plots of carbon and oxygen isotopes show distinct clustering of data points for individual species, pointing to species-specific fractionation during the foraminifer's life time. Cross plots of the elemental shell compositions also show species-specific clusters of data points, possibly indicating primary and/or early-diagenetic mineralogical differences that potentially affect the isotopic shell chemistry apart from or along with the vital effects. The influence of diagenetic alteration is studied by comparing isotope data and geochemical composition of the shells from samples with different degrees of preservation. Our study aims at providing important information for selecting species that are suitable for studies of stable isotopes and temperature reconstructions in the Cretaceous. Furthermore, we compare single species measurements of pristine shells with isotope data from bulk sediments to assess the reliability of bulk sediment data, as they are increasingly used for chemostratigraphic correlation and reconstruction of relative temperature trends in the Cretaceous.

This change occurred during an earlier phase of gymnosperm diversification, followed by early angiosperm expansion in concert with co-radiation of numerous insect lineages. Our study focuses on insect herbivory from these late Middle Jurassic and mid Early Cretaceous intervals, where we compare patterns of autecological associations between plants and phytophagous insects at multiple temporal and spatial scales. The first of two superlocalities is the late Middle Jurassic Jiulongshan Formation that forms the Daohugou Biota of Ningcheng County, Inner Mongolia. The second superlocality is the Yixian Formation of Early Cretaceous age, and includes two localities from the Jehol Biota, Liaoning, a locality from Ningcheng County, and another from Duolun County, both from Inner Mongolia. The host plants principally are Lycopodiales, Selaginellales, Equisetales, Filicales, Bennettiales, Cycadales, Ginkgoales, Gnetales, coniferophytes, and various pteridosperms. Damaged plants organs from these biotas were classified based on membership in a functional feeding group and assignment to a diagnosable damage type (DT), listed in the Guide to Insect (and other) Damage Types on Compressed Plant Fossils (Labandeira et al., 2007). We recorded foliar hole feeding, margin feeding, skeletonization, and surface feeding. Consumption of inner plant tissues was done by insects involved in galling, mining, oviposition, piercing-and-sucking and seed predation. Each censused plant organ was tabulated and scored for the presence or absence of particular insect DTs, and then statistically analyzed to reveal the diversity, frequency, abundances and host-species distributions of insect damage at specific intervals, localities, habitats and plant hosts. Preliminary results show that the Daohugou Biota has more plant species and associated herbivore DT diversity than the Jehol Biota. This contrast ultimately may reflect changing microclimate within the immediate region as well as the extinction of earlier plant and insect taxa during early angiosperm expansion.

AN - 868007344; 2011-043865 AB - Two major events characterize plant-insect associations during the preangiospermous Mesozoic. First was Gondwanan diversification of plant lineages and expansion of herbivory during the Middle to Late Triassic interval, documented in the Molteno Formation of South Africa. This event hosts a diverse spectrum of 79 damage types inflicted by insect herbivores, including external feeders, piercer-and-suckers, leaf miners, gallers, seed predators and ovipositing insects on a broad spectrum of horsetails, ferns, cycads, conifers, peltasperms, corystosperms, ginkgophytes and gnetaleans. Many of the herbivores were host specialists that targeted particular host-plant taxa and their tissues. Molteno herbivore associations often are local, suggesting a complex mosaic of spatiotemporally fleeting associations. The second event was expansion of associations during the Middle Jurassic of western Eurasia, involving long-proboscid, fluid- and pollen feeding lineages of Mecoptera (aneuretopsychine scorpionflies), Neuroptera (kalligrammatid lacewings), and Diptera (brachyceran flies). Suspect plant taxa accommodating these long siphonate mouthparts were cheirolepidiaceous conifers, caytonialeans, ginkgophytes, bennettitaleans and gnetaleans providing secretory fluid and pollen rewards. This distinctive feeding type formed a gymnosperm pollination mode lasting to the Mid-Cretaceous, at which time angiosperm pollination originated and replaced older gymnosperm associations. Importantly, Middle Triassic to Early Cretaceous atmospheric concentrations range from 12-19 pO (sub 2) , well below the current norm. Such low partial pressures exert distinctive responses from insects with a respiratory system of ramifying tubules originating from valvular spiracles. Also, atmospheric pCO (sub 2) was considerably more elevated than current levels, suggesting low levels of accessible nitrogen from foliage, tissue secretions and pollen. Insect herbivores and pollinators require both O (sub 2) levels adequate for respiratory activity and access to nitrogen sufficient for body maintenance, reproduction and activities such as flight. Both requirements may explain the expansion of herbivory and pollination as a consequence of greater access to nitrogen while maintaining safe levels of respiratory metabolism.

AN - 868007329; 2011-043862 AB - One of the most conspicuous patterns of life on Earth is the increase in diversity from the poles to the equator, which applies to most taxa. For flowering plants (angiosperms), it has been suggested that this latitudinal gradient has been present since the Albian ( approximately 110Ma), when angiosperms were undergoing their initial diversification. However, the small number of Lower Cretaceous studies in tropical areas has made it difficult to test this and other biogeographical patterns. The main objective of this study is to determine whether a modern-like latitudinal diversity gradient for angiosperms was present during the Aptian-Albian interval, through the comparison of quantitative data from high and tropical paleolatitudes. The data used in this study are datasets from North America and Brazil. Additionally we reconstructed the floristic composition of an Aptian-Albian tropical ecosystem from Colombia. Our preliminary analyses offer mixed results. On one hand, there are no significant differences between the number of angiosperm species among the Colombian tropical site and the high latitudes of North America (5 and 3 species in average per sample, respectively). These results would indicate the absence of a modern-like latitudinal gradient for angiosperms during this time interval. On the other hand, the Brazilian ecosystems show significantly higher number of angiosperm species than the high latitudes of North America (7 and 3 species in average per sample, respectively), which would indicate the presence of a modern-like latitudinal gradient. One possible cause of this inconsistency could be the climatic difference between the hypothesized humid west and the arid east of South America, which could affect the composition of the floras. Currently we are generating new quantitative data for other six paleotropical sites of similar age in order to make more robust latitudinal comparisons. These new data will allow us to determine more accurately the floristic composition of tropical ecosystems of Lower Cretaceous age, the patterns of tropical angiosperm radiation and diversification, the prevalent climatic conditions in which they diversified and the biogeographical patterns for other groups of plants during that period of time.

Drilling during the 2007-2009 field seasons recovered a stratigraphically complete Turonian sequence of claystones and clayey siltstones, much of which yields diverse benthic and planktonic foraminiferal assemblages exhibiting "glassy" preservation (no apparent test recrystallization at the submicron scale). During the Turonian the drill sites were located at about 30 degrees south paleolatitude and the sediments were deposited at an upper bathyal paleodepth. The extraordinarily good microfossil preservation enables reliable estimates of surface and bottom water temperatures spanning a 2.5 m.y. period from the earliest Turonian Whiteinella archaeocretacea Zone through the late middle Turonian Helvetoglobotruncana helvetica Zone. This provides an opportunity to test the greenhouse ice sheet hypothesis that has been proposed based on sequence stratigraphic interpretations from the lower Turonian of the New Jersey Coastal Plain and in the Western Interior. At least two benthic and three planktic species were analyzed throughout a 120 m sequence at TDP Site 22 and a 70 m sequence at TDP Site 31. Results show surprisingly coherent trends with high stability in both delta (super 18) O and delta (super 13) C values. Using standard assumptions for the oxygen isotopic composition of the Cretaceous ocean, we calculate that sea surface temperatures averaged 32-34 degrees C and the bottom water averaged 18-21 degrees C. Consistency in benthic and planktic delta (super 18) O and delta (super 13) C values and lack of evidence for changes in sea level on the East African passive margin indicate that the intermittent polar ice sheets that have been proposed for this time period either did not exist or were too small to be detectable in foraminiferal oxygen isotope records.

Most notably, the largest cetaceans are up to a hundred times larger than the largest terrestrial mammals. However, little is known about the macroevolutionary processes involved. We present new results suggesting that a constrained diffusion process is sufficient to explain patterns of size evolution. First, we show that the distribution of extant cetacean body sizes can be predicted, with no adjustable parameters, from a diffusion model fitted to terrestrial body size evolution. Second, we show that the dynamics of cetacean body-size disparity observed in the fossil record over the past 55.8 My can be predicted from the same model. More generally, this model predicts a two-phase process for morphological macroevolutionary dynamics. The first phase is radiative, in which disparity is dominated by morphological diffusion and is uncoupled from taxonomic diversity. For cetaceans, this period ended in the late Eocene or early Oligocene, which coincided with the emergence of the suborders Mysticeti and Odontoceti. The second phase, which is ongoing for cetaceans, represents equilibrium, where disparity is controlled by diversity and thus presumably by intraspecific competition. In this phase, the largest morphological disparities should co-occur with diversity maxima. We conclude by suggesting that this two-phase model may be generally characteristic of macroevolutionary dynamics.

In the Tanzania Drilling Project exceptionally well preserved foraminiferal shells have been retrieved from Cenomanian and Turonian sediments with low carbonate and high clay content. This allows for a comparison of the primary shell material of individual species concerning their mineralogy, chemistry and stable isotopes. It further offers the unique opportunity to compare pristine shells that are glassy with slightly re-crystallized shells that are still well preserved and hollow, but appear more "frosty" or less translucent. The influence of these first processes of diagenetic alteration on the shell geochemistry and isotope signatures is studied by applying a combination of light microscope imaging, scanning electron microscope analyses, cathodoluminescence and microprobe observations. To exclude variation due to environmental factors or vital effects we compare specimens from the same sample and within the same species. Cathodoluminescence studies confirmed the presence of aragonitic shells for a number of species, testifying to the excellent preservation of the material. Their isotopic composition shows a considerable offset as compared to other benthic species. There is also a large difference in oxygen isotopes between benthic and planktic foraminifera. Slightly re-crystallized shells of benthic foraminifera show isotope values that fall within the range of variability of the species. However, the presence of cement can lead to a decrease in delta (super 18) O and becomes evident from bright orange linings under the cathodoluminescence microscope and from a rough shell surface under the SEM. Microprobe analysis reveals that manganese and iron increase in the cemented areas while strontium decreases. A similar trend is observed by comparing the shell chemistry of glassy and less translucent specimens of the same species, indicating some alteration of the primary shell material during re-crystallization.

Pristine specimens from the Tanzania Drilling Project provide unprecedented insight into an enigmatic Cretaceous microfossil group AN - 864944738; 2011-041941 AB - Calcispheres constitute the second-most abundant calcareous microfossils of many Late Cretaceous rocks and show significant spatial and temporal blooms, the most important of which is the Late Cenomanian-Early Turonian global calcisphere bioevent associated with OAE2. Because of their common appearance calcispheres could give substantial paleo-ecological information if their taxonomic affinities would be better known. However, a lack of morphological features limits our understanding of what these microfossils actually are. The most common calcispheres belong to the genus Pithonella. They are 20 to 180 micrometers in diameter and have been interpreted as calcareous cysts of dinoflagellates. However, the dinoflagellate cyst nature of Pithonelloideae has been controversial due to their lack of dinoflagellate-specific features. Unusually well-preserved Pithonelloideae are abundant in the Turonian from Tanzania. The pristine specimens reveal a number of shell-morphological features that have never been described before. Our study aims at revising the taxonomy of this complex microfossil group based on these new morphological findings. We combine light-optical imaging, SEM-imaging, cross-section study and microprobe analysis on single specimens. Most crucial to the determination of their taxonomic affinity with dinoflagellates is our discovery of an operculum-like structure that can be associated with the apical 3' plate known from the peridinialean tabulation pattern of dinoflagellates. Furthermore, comparison between Pithonella sphaerica and the known calcareous dinoflagellate cyst Pirumella krasheninnikovii reveals striking biomineralogical similarities in wall-crystal architecture and chemistry. Such similarity hints at a common biomineralization principle in both species. Stable oxygen isotope values of Pithonella plot with the values of planktic foraminifera suggesting a habitat of Pithonella near the water surface.

His analysis of the number of families within classes revealed that diversity history could be described simply by the successive dominance of three evolutionary faunas: the Cambrian, Paleozoic, and Modern. Here, we perform a similar analysis on his genus-level database using cluster analysis, but we split the ten most diverse classes in the dataset into subtaxa in order to observe additional details of taxonomic turnover. We also converted raw numbers of genera to proportions because we were most interested in changes in dominance (and because biases may affect raw counts of diversity). We identified twelve faunas from the resulting cluster analysis. These faunas were not simple subdivisions of Sepkoski's faunas; for example, some bivalve subtaxa grouped with faunas that most resembled Sepkoski's Modern fauna, but others grouped with faunas that most resembled his Paleozoic fauna. These faunas can also be related to the concept of Ecologic Evolutionary Units (EEU's). Dominance shifted rapidly from fauna to fauna in the early Paleozoic and then slowed as rates of extinction and origination in the biosphere declined. For example, five of the twelve faunas reached their maximum proportional diversity by the Ordovician. As in Sepkoski's original analysis, the Permian extinction is obvious because it decimated a major fauna (the late Paleozoic fauna). However, in this analysis, the other mass extinctions are more apparent as well--they either truncated or permanently reduced the diversity of various faunas. Major radiations (Cambrian, Ordovician, Mesozoic-Cenozoic) correspond with the expansion of new faunas. We use this analysis to examine general changes in the ecological composition of the marine fauna by assigning higher taxa to broad ecological categories. For example, taxa that contain infaunal, predatory, and motile members increased in relative diversity through time.

Most research in this area has focused on spatial gradients of species richness, with a smaller area of emphasis dedicated to understanding the temporal dynamics of richness. However, few attempts have been made to understand the linkages between the spatial and temporal patterns related to richness. Here, we argue that spatial and temporal richness patterns and the processes that drive them are inherently linked, and that our understanding of richness will be substantially improved by considering them simultaneously. The species-time-area relationship provides a case in point: successful description of the empirical spatio-temporal pattern led to a rapid development and testing of new theories. Other areas of research on species richness could also benefit from an explicitly spatio-temporal approach, and we suggest future directions for understanding the processes common to these two traditionally isolated fields of research.

This review concerns the amount of water in nominally anhydrous minerals from mantle and mantle-derived rocks: peridotites, eclogites, megacrysts, basalts and kimberlites. Trends between internal and external parameters and water content in olivine, pyroxene, and garnet of mantle rocks allow us to identify what controls their H intake. The water content of pyroxenes and garnets in peridotites appears to depend primarily on mineral chemistry, while that of olivines may more readily reflect water activity and water fugacity conditions in the mantle. In eclogites, both mineral chemistry and metamorphic pressure control the water intake of pyroxene and garnet. The water content of minerals in crystallized melts (basalt and kimberlite phenocrysts, xenocrysts, and megacrysts) is determined by the degree of differentiation, the amount of water in the parent melt, and degassing. Basalt and cumulate minerals from Martian meteorites may be as water-rich as their Earth equivalents. No water has been detected at present in Moon minerals but low amounts in degassed basaltic glasses signify that deep Moon reservoirs may still retain water. The presence of water in mantle minerals, typically amounts of tens to hundreds of ppm, enhances their deformation properties. Water contents of peridotite minerals in the oceanic upper mantle, in and around cratons, and in subduction zones may have tremendous influence on Earth's geodynamics.

These have been grouped by other authors in extended monogenetic volcanic fields such as Michoacan-Guanajuato, Chichinautzin, Apan and Los Tuxtlas. Here we present geological and morphological data of a relatively unknown group of monogenetic volcanoes located on the east flank of the Cofre de Perote volcano (CP), around the city of Xalapa in the state of Veracruz, Mexico. Within an area of about 2400 km (super 2) , the "Xalapa Monogenetic Volcanic Field" (XMVF) contains over 50 late Quaternary volcanoes. Most of them are scoria cones, but small shield volcanoes and tuff rings also occur. The lava flows produced by these volcanoes are constrained by an abrupt topography and cover a great percentage of the surface on the eastern and northeastern flanks of CP, between 3000 and 500 m a.s.l. The representative rocks of the different volcanic centers include olivine basalt, basaltic andesite with phenocrysts of plagioclase, pyroxene and minor olivine, and andesite with phenocrysts of plagioclase and pyroxene. SiO (sub 2) and Al (sub 2) O (sub 3) contents of the rocks vary between 45 and 62 wt% and 15 to 18 wt%, respectively. Most of the basaltic rocks have MgO contents between 4.2 and 9 wt%, Ni and Cr concentrations between 23 and 180 and 10 to 380 ppm, respectively, with a typical calc-alkaline behavior. Trace elements suggest two types of magmas; the most abundant are characterized by an enrichment of LILE and LREE with negative anomalies of Nb and Ti, which denote a calc-alkaline affinity. Others are LILE depleted and show high concentrations of MgO, Cr, and Ni, which is typical of primary calc-alkaline magmas. The mean scoria cone morphological values are: cone height (Hco)=90.8 m, cone diameter (Wco)=686.38 m, crater diameter (Wcr)=208.49 m and 0.12 km (super 3) for the cone volume. We dated twelve different scoria cones using the (super 40) Ar/ (super 39) Ar method; for the other cones we used morphologic indicators such as the ratio of the scoria cone height to basal diameter (Hco/Wco) and maximum slope angle. Additionally, vegetation type, and cone and lava flow morphologies were also considered in order to determine rough relative ages. In general, the ages fall into three groups, those older than 2.0 Ma, those between 0.25-0.40 Ma and those less than approximately 0.1 Ma.

It rises in a volcanic field strewn with monogenetic volcanic cones, maars and three other large volcanoes mostly dormant since the late Pliocene: Santa Marta, San Martin Pajapan and Cerro El Vigia. The latest eruptive event of San Martin occurred in 1793 and was described by Don Jose Mariano Mozino, a naturalist under the commission of the Viceroy of the then New Spain. In this work we present results of the study of this eruption based on historical accounts and field observations. We identified an ash deposit around the volcano related to the 1793 eruption, mapped its distribution and determined its granulometric, petrographic and geochemical characteristics. These studies suggest that the volcano began its activity with explosive phreatomagmatic explosions, which were followed by Strombolian activity; this period lasting from March to October 1793. The activity continued with an effusive phase that lasted probably 2 years. The eruption covered an area of about 480 km (super 2) with at least 1 cm of ash; the fines reaching distances greater than 300 km from the crater. A total mass of about 2.5X10 (super 14) g was ejected and the volcanic columns probably reached altitudes of the order of 10 km during the most explosive phases. The lava emitted formed a coulee that descended the northern flank of the volcano and has an approximate volume Xf 2.0X10 (super 7) m (super 3) .

NIB landforms are typically 400-1000 m in diameter and 30-100 m deep and are invariably surrounded by steep walls cut into one or more basaltic lava flows. NIB landforms lack evidence for a primary volcanogenic origin through either collapse or youthful eruptive activity. In the Pliocene portion (4 - 2 Ma) of the Plio-Quaternary Camargo volcanic field of Chihuahua (Mexico), they are relatively numerous and are best developed at the margins of a gently sloping (3-5 degrees ) basaltic lava plateau and near major fault scarps. Mature NIB landforms have ring-like circular drainage patterns and central elevations marked by small volcanic necks and associated radial dikes intruded into basaltic scoria-fall and /or agglutinate deposits. We interpret NIB landforms to be erosional in origin. They develop where a cinder cone is surrounded by one or more sheet-like lava flows from one or more separate subsequent vents. Once eruptive activity ceases at the younger volcano(es), fluvial erosion gradually produces a ring-like drainage pattern along the contact between the lava and the older cinder cone. As a response to a marked contrast in resistance to erosion between lava flows and unconsolidated or poorly lithified pyroclastic deposits, the older cinder cone is preferentially eroded. In this manner, a ring-shaped, steep sided erosional basin, preformed by the scoria cone, is produced; eventually fluvial erosion exposes the central neck and dikes. The volume, relief, and age of the volcanic field are key factors in the formation and preservation of a NIB landform. They form in volcanic fields where lava emissions are sufficiently vigorous to engulf earlier cinder cones. Relief and associated high rates of fluvial erosion play an important role in NIB development, as demonstrated by their locations in the Camargo volcanic field. Fully developed NIB landforms are not found in Quaternary volcanic fields, probably because erosion has not had sufficient time to generate their characteristics features. NIB landforms are also absent in Miocene fields, because erosion has proceeded too far, and thus has completely removed any NIB landform that may once have existed. The Camargo volcanic field is the only major area of Pliocene intraplate eruptive activity in northern Mexico, and the only place where NIB landforms are relatively abundant.

This eruption, dated at 74 ka, produced the 2800 km (super 3) Youngest Toba Tuff (YTT) and ash-fall. Quartz-bearing silicic pumices ranging from 68 to 77wt.% SiO (sub 2) indicate that the YTT magma was zoned compositionally and mineralogically. Prior to the YTT eruption, two other silicic quartz-bearing tuffs known as the Middle Toba Tuff (MTT) and the Oldest Toba Tuff (OTT) were erupted from Toba at 0.501 Ma and 0.840 Ma respectively. Although the volatile contents of the Toba magmas are poorly constrained, aerosols generated by the YTT eruption are generally thought to have caused a global volcanic winter. An evaluation of the pre-eruptive dissolved gas contents of the YTT magma is fundamental to understanding the global effects of this eruption. We used melt inclusions in quartz crystals to determine the dissolved H (sub 2) O, CO (sub 2) , S, Cl, and F contents of the YTT, MTT, and OTT magmas. Quartz crystals selected from pumice blocks and welded tuffs that spanned the compositional ranges of the three units were chosen for study. Major and trace element analyses of melt inclusions were also conducted to characterize melt evolution and provide context to the volatile data. Melt inclusions from the YTT, MTT, and OTT are rhyolitic in composition (73-77 wt.% SiO (sub 2) ) and have overlapping, indistinguishable major element trends. Inclusions from the large eruptions (YTT and OTT) have similar geochemical relationships where the most evolved melt inclusions occur in the least silicic bulk rock samples and are more evolved than their matrix glasses. In contrast, the least evolved melt inclusions occur in the most silicic samples and either overlap with, or are less evolved than their matrix glasses. These patterns can be explained if quartz crystals in the least silicic magmas were inherited from more evolved melt, while those in the most silicic melt formed in-situ. Several lines of evidence suggest that crystal settling of early-formed quartz crystals in long-lived magma bodies was an important process in the YTT and OTT magmas. Trace element data from the YTT melt inclusions have wide ranges (Rb=250-830 ppm, Ba=<10-485 ppm) and mostly support these models; however, incompatible trace elements are enriched 2-3x over their matrix glass compositions in all samples. In the smaller MTT, melt inclusions overlapped with the compositional range of the bulk rock samples and are consistent with in-situ crystallization. FTIR analyses indicate that the YTT, MTT, and OTT melts contained about 4.0-5.5, 2.0-5.5, and 2.0-5.5 wt.% H (sub 2) O respectively. CO (sub 2) contents in all units are generally <100 ppm and Cl is <2000 ppm. Water gradients occur in all 3 tuffs, Cl gradients are evident only in the YTT, and the least silicic samples from all units had no detectable CO (sub 2) . Sulfur contents in melt inclusions are low in all samples (<32 ppm) and overlap with matrix glass S contents. Applying broad degassing constraints, about 10 (super 14) g of H (sub 2) SO (sub 4) aerosols were likely loaded into the atmosphere during the YTT eruption, 2 orders of magnitude less than previous petrologic estimates. Considerably more Cl and F, about 10 (super 15) g of each, may have been part of the YTT aerosol cloud.

This active volcano comprises four evolutionary stages, ranging in age from 0.65Ma to the Holocene, and is surrounded by Quaternary monogenetic scoria cones and maar volcanoes. Magmatic products of the stratocone range from basaltic andesites to rhyolites and the cinder cones erupted basalts and basaltic andesites. All rock compositions form a continuous calc-alkaline suite. Petrogenetic processes involved in magma generation and evolution include fractional crystallization and mid-crustal assimilation. Trace element patterns with elevated Ba/Nb, positive Pb spikes, and Th enrichments indicate contributions from subducted sediment. Low Ba/Th ratios suggest melting of hydrous sediment without significant loss of fluid-mobile elements prior to melting. Sr-Nd isotopic ratios of Pico de Orizaba and cinder cones are nearly chondritic and are located on a mixing curve between Pacific MORB and Paleozoic crust of SE Mexico. However, vertical Nd distributions in an (super 87) Sr/ (super 86) Sr vs. epsilon Nd diagram cannot be explained by crustal assimilation and indicate contributions of a sedimentary component with unradiogenic Nd. In contrast to other eastern MVB volcanic centres, Pico de Orizaba magmas are derived almost exclusively from a depleted mantle source. Compared to other MVB stratocones, Pico de Orizaba shows the least radiogenic Nd isotope ratios at nearly identical (super 87) Sr/ (super 86) Sr. Steep trends in a (super 206) Pb/ (super 204) Pb vs. (super 207) Pb/ (super 204) Pb diagram favour the involvement of young, (super 207) Pb-enriched oceanic sediments in magma generation processes of Pico de Orizaba volcano. The Pb isotope data do not support any assimilation of lower crustal Grenvillian basement.

Here we investigate the degassing and vapor-melt partitioning of volatiles (H (sub 2) O, CO (sub 2) , S, Cl) in monogenetic volcanoes from the subduction-related Michoacan-Guanajuato Volcanic Field (MGVF) in central Mexico. Olivine-hosted melt inclusions from these volcanoes contain variably degassed melts that were trapped over a wide range of pressures from <50MPa to approximately 300 MPa. Variations in melt compositions and volatile contents provide evidence that crystallization and differentiation were driven by degassing of H (sub 2) O. Melt CO (sub 2) and H (sub 2) O concentrations are highly variable, and much of the variation does not conform to equilibrium open- or closed-system degassing paths. Instead, we suggest that gas-fluxing - partial re-equilibration of magmas with CO (sub 2) -rich gases rising from depth - can explain the variable CO (sub 2) and H (sub 2) O concentrations in the melts. Such fluxing may be common in basaltic systems, and it increases the extent of crystallization during magma ascent by removing dissolved H (sub 2) O from vapor-saturated (but H (sub 2) O-undersaturated) melts. Strong degassing of S and Cl during magma ascent and crystallization begins at pressures of approximately 50 MPa. Using the relationship between degassing and crystallization, we calculate apparent vapor-melt partition coefficients for S and Cl. Our results show that, overall, S partitions more strongly into the vapor phase than Cl, consistent with published experimental data and thermodynamic models, and that vapor-melt partitioning of S increases more strongly with decreasing pressure than Cl. The S and Cl partitioning behavior inferred from the melt inclusion data are consistent with the gas fluxing model suggested by the H (sub 2) O and CO (sub 2) data.

Three 'type' sections provide a complete tephra record for the eruption, which is placed in a temporal framework by comparing both bulk tephra and olivine phenocryst compositions to dated samples of lava and tephra. Our data support the hypothesis of Luhr (2001) that the first four months of activity were fed by a magma batch (Phase 1) that was distinct from the magma that supplied the subsequent eight years of activity. We further suggest that the earliest erupted (vanguard) magma records evidence of temporary residence at shallow levels prior to eruption, suggesting early development of a dike and sill complex beneath the vent. Depletion of this early batch led to diminished eruptive activity in June and July of 1943, while arrival of the second magma batch (Phase 2) reinvigorated activity in late July. Phase 2 fed explosive activity from mid-1943 through 1946, although most of the tephra was deposited by the end of 1945. Phase 3 of the eruption began in mid-1947 with rapid evolution of magma compositions from basaltic andesite to andesite and dominance of lava effusion. The combined physical and chemical characteristics of the erupted material present a new interpretation of the physical conditions that led to compositional evolution of the magma. We believe that syn-eruptive assimilation of wall rock in a shallow complex of dikes and sills is more likely than pre-eruptive assimilation within a large magma chamber, as previously assumed. We further suggest that waning rates of magma supply from the deep feeder system allowed evolved, shallowly stored magma to enter the conduit in 1947, thus triggering the rapid observed change in the erupted magma composition. This physical model predicts that assimilation should be observable in other monogenetic eruptions, particularly those with low pressure melt inclusions and with eruption durations of months to years.

The volume of the island is estimated at approximately 4.2 km (super 3) ; the volume above sea level is estimated to be approximately 0.03 km (super 3) . The dominant volcanic rock type exposed above sea level is analcime-cemented basaltic tuff-breccia, the rapidly lithified products of hydrovolcanic eruptions; however, subaerial scoria-fall deposits and lava flows are also present. Ten analyzed Isla Isabel volcanic rocks are relatively homogeneous alkali basalts with 4.5-6.4 wt.% nepheline in the CIPW norm. Compared to other analyzed Mexican intraplate-type volcanic rocks from oceanic and continental localities, at the same MgO content, the Isabel samples are depleted in TiO (sub 2) , FeO (super total) , and Na (sub 2) O, and moderately incompatible trace elements (e.g., Sm, Eu, Tb, and Zr). On the other hand, they are enriched in CaO and Al (sub 2) O (sub 3) , and relatively compatible trace elements (e.g., Lu and Sc). It is suggested that relative to other Mexican intraplate alkaline lavas the Isabel lavas were derived by higher degrees of melting at lower pressures of mantle that is characterized by ancient HIMU-like isotope systematics. Isabel olivine phenocrysts and their spinel inclusions range to Mg#s that overlap with the peridotite minerals in the accompanying mantle xenoliths, which has not been reported at other Mexican xenolith localities. Olivine-hosted glass inclusions in rapidly quenched scoria yielded the first estimates for volatile contents in Mexican intraplate-type mafic melts; maximum values are: 1.3 wt.% H (sub 2) O, 2241 ppm CO (sub 2) , 1500 ppm F, 1300 ppm S, and 1200 ppm Cl. Isabel peridotites (Ol+ or -Hy+ or -Di+Sp+ or -Pl) include dunites, harzburgites, and rare plagioclase-harzburgite, and are depleted in clinopyroxene in comparison to other Mexican peridotite localities where lherzolites dominate; Isabel peridotite clinopyroxenes are also depleted in Na (sub 2) O compared to other Mexican localities, another reflection of their refractory nature. Pressure estimates for Isabel xenoliths based on olivine-clinopyroxene Ca exchange indicate that they equilibrated at relatively low pressures (5.9-15.5 kb) compared to other Mexican peridotites ( approximately 10-20 kb), which is consistent with the presence of a single plagioclase-harzburgite xenolith. The refractory character of the Isabel xenoliths is consistent with the results of the Alarcon segment of the PESCADOR seismic experiment, and Lizarralde et al.'s [Lizarralde, D., Axen, G.J., Brown, H.E., Fletcher, J.M., Gonzales-Fernandez, A., Harding, A.J., Holbrook, W.S., Kent, G.M., Paramo, P., Sutherland, F., Umhoefer, P.J., 2007. Variation in styles of rifting in the Gulf of California. Nature 448: 466-469] hypothesis that wide, magma-poor rifted margins result from rifting of depleted mantle.

In this region, centered at 101 degrees W, Quaternary volcanism is displaced approximately 100 km toward the back of the arc. This embayment is roughly aligned with the projected position of the Orozco Fracture Zone (OFZ), which separates segments of the Cocos Plate that differ in age by approximately 5 Ma. The fracturing of the oceanic lithosphere associated with the OFZ appears to have caused alteration and increased the buoyancy of this approximately 100 km-wide linear feature. Several indicators of the buoyancy of the OFZ have been reported, including shallowing of the Middle America Trench (MAT), seaward advancement of the shoreline, and the uplift and exposure of deeply buried and deformed Jurassic to Oligocene rocks that comprise the TG region. Arc volcanism in the regions surrounding the TG provides constraints on the subduction of the OFZ. In the central MVB, enrichment in fluid-mobile elements such as Ba, Sr, P (sub 2) O (sub 5) , Pb and K (sub 2) O typically decreases with distance from the Middle America Trench, consistent with progressive dehydration of the down-going slab. Numerous studies in the central MVB have demonstrated that this fluid-mobile element enriched signature results from flux-induced melting at the front of the arc, while decompression melting of asthenospheric mantle peridotite is dominant at the back of the arc. The data presented here (a compilation of available geochemical data and new XRF major and trace element analyses of lavas erupted adjacent to the TG) shows that the volcanism that occurs behind the TG exhibits an anomalous fluid signature (high K (sub 2) O, P (sub 2) O (sub 5) , Ba, and Pb) superimposed on compositions similar to those from the extensional regions in northern Mexico. We propose that these distinctive structural and geochemical characteristics arise from subduction of the OFZ. Increased buoyancy of the fracture zone may cause it to subduct at a shallower angle. Therefore, the OFZ portion of the slab reaches the P/T conditions for de-volatilization further from the Middle America Trench, resulting in the profound offset of the arc toward the back and the fluid signature from the slab superimposed on back-arc, extension-related intraplate basalts.

The eruptions that have had the most impact on climate typically erupted oxidized and anhydrite-bearing magma. The >9km (super 3) of dacite magma erupted during the VEI 6 eruption of Huaynaputina (Peru) in 1600 is oxidized (fO (sub 2) NNO +1.4) but does not contain magmatic anhydrite. Yet it is thought to have a significant impact on climate. Herein we follow the approach that S contents in magmatic apatite grains can be used to provide an independent estimate of the magnitude and source of the atmospheric sulfur loading. Apatite SO (sub 3) concentrations of 0.09 to 0.17 wt.% yield an estimate of approximately 0.8 Mt of total erupted sulfur derived from degassing of the melt. This is considerably less than the stratospheric sulfur input of 16-55Mt of S estimated from ice core data and requires that much of the stratospheric sulfur load from Huaynaputina was from other sources than the melt. While a fluid phase in equilibrium with the melt is a likely source, a significant contribution from combustion of sulfur from a fossil hydrothermal system excavated during eruption is evidenced by comminuted hydrothermal debris and lithics that make up to 2.5 to 10 wt.% of erupted material. We calculate that up to 22% of the total S budget of the eruption could reasonably be attributed to combusted hydrothermal sulfur. Thus, three sources of sulfur: the melt, a coexisting fluid phase, and external hydrothermal sulfur, appear to explain the atmospheric input from this eruption. Our work confirms that unraveling the S budget of large silicic eruptions is extremely complex and requires a multi-faceted approach based on a detailed understanding of the eruption.

The debris avalanche deposit covers an area of 48 km (super 2) , has an average thickness of 35 m, and a volume of 1.7 km (super 3) , with an H/L ratio fm0.13. Along the La Lumbre ravine, the deposit forms a series of flat terraces up to 65 m thick. A pyroclastic flow deposit overlies the debris avalanche deposit, suggesting that the Colima collapse was accompanied by a magmatic component. The debris avalanche deposit dammed the Armeria River, forming a temporary lake that accumulated a water volume of approximately 0.19 km (super 3) . The subsequent breaking of the dam formed a debris flow that travelled at least 20 km along the Armeria River, emplacing 15-70 m thick deposits. The debris flow deposits cover a surface of 6.4 km (super 2) and have a volume of approximately 0.2 km (super 3) . The avalanche deposit contains fragments of carbonized wood that where dated at 3600+ or -120 yr. BP by Komorowski et al. (1997). This deposit underlies a younger debris avalanche (2505+ or -45 yr BP), and a debris flow deposit with pottery shards and charcoal dated at 1940+ or -90 yr BP. These pottery shards likely related to the Capacha people (820-300 yr BC) indicating that the region has been inhabited during the last 3000 years. A future collapse of Volcan de Colima in the same direction may affect several towns for a total population of circa 40,000.

The northern flank of this edifice collapsed approximately 9690 years B.P. resulting in a 80 km (super 2) -covering clast-supported deposit that lacks substantial matrix, fine, weak or hydrothermally altered materials. The deposit can be subdivided into three morphologically distinct areas which are each accompanied by specific, and often unique, deformation features in the underlying and adjacent volcaniclastic and lacustrine sediments. From these features, a complex history of pre- and syn-avalanche events was reconstructed beginning with edifice-spreading on the weak substrate material prior to and in preparation of part of the flank collapse event. The north-eastern flank in particular was strongly coupled with the deforming substrate material as is still evident in its extensional profile and the unique mode of failure during the catastrophic event resulting in the deposition of what resembles non-volcanic blockslide deposits rather than the typical hummocky volcanic debris avalanche morphology. This latter type of failure occurred at the north-western flank of Jocotitlan volcano where few signs of substrate interactions are preserved in a deposit dominated by large conical hummocks. In addition to substrate response, interaction with pre-avalanche topography in the eastern deposit area facilitated the emplacement of a lobe roughly perpendicular to the flank failure direction, at apparent high emplacement velocity, and with longitudinal ridges as its most striking surface expression.

All rocks from this area, including the basanites and minettes, show enrichment in LILE (e.g., Cs, Ba, and Sr) and depletion in HFSE (e.g., Ta and Ti), generally considered to be a characteristic of subduction-related magmas. The isotopic ratios of Cantaro-Colima rocks show the following ranges: (super 87) Sr/ (super 86) Sr 0.70282-0.70395, (super 143) Nd/ (super 144) Nd 0.51282-0.51305, (super 206) Pb/ (super 204) Pb 18.54-18.70, (super 207) Pb/ (super 204) Pb 15.53-15.61, and (super 208) Pb/ (super 204) Pb 38.09-38.52. The most mafic basaltic andesite from Volcan Cantaro is isotopically the most depleted rock, similar to MORB and oceanic basalts from seamounts in the adjacent oceanic basins. It has the least radiogenic Sr and Pb and the most radiogenic Nd yet measured from any locality in the MVB. The combined geochemical and isotopic evidence is compatible with the generation of both alkaline and subalkaline magmas of the Cantaro-Colima volcanic chain in the mantle wedge by fluid-transport to the mantle from the subducted plate. The isotopic data are also generally consistent with the actual physical mixing of subalkaline and alkaline basanite-minette magmas to generate intermediate alkaline magmas. The geochemical and isotopic data from the western part of the MVB, including the Cantaro-Colima volcanic chain, however, also reflect the tectonic complexity of simultaneously ongoing subduction and rifting, requiring more complex petrogenetic processes and a chemically and isotopically heterogeneous mantle.

We present a detailed tephrochronological study of its Holocene proximal tephra-fall, pyroclastic surge and pyroclastic flow deposits based on 98 new stratigraphic sections, 183 new dendrocalibrated radiocarbon [ (super 14) C] age determinations, 209 new geochemical analyses of pumice and ash, >50 texture and mineral (point-counting) mode determinations and 230 grain-size analyses. These results provide a much clearer understanding of the explosive eruptive behavior of Volcan de Colima during the past 10,000 years. Our data reveals that only one of the many eruptions described in historic documents has been large enough to be preserved. We discuss the major and trace element geochemistry and petrology of the Holocene tephra and compare it with the currently erupting calc-alkaline andesites and alkaline minettes and basanites from the adjacent cinder cones. It appears that several of the oldest ( approximately 12,000-6000 yrs BP) samples of the Holocene tephra may record the last episodes of calc-alkaline and alkaline magma mixing as first described in the pioneering work of Luhr and Carmichael (1981). Finally, the tephrochronological record from the northern, downwind side of the Colima Volcanic Complex is compared with the extensive, radiocarbon-constrained, record of Holocene debris-avalanche deposits on the south side of the complex, to build a more integrated picture of its past volcanic activity.

These olivine-rich basalts and trachybasalts have up to 8% MgO, with high Ni and Cr contents, but highly variable incompatible element concentrations. Mafic lava flows and cinder cones at the southern end of the graben lack phenocrystic plagioclase. The northern samples have relative Ta-Nb depletions and K, Pb and LREE enrichment. These samples strongly resemble rocks of the nearby arc volcanoes Copahue and Caviahue, including their Fe-Ti enrichment relative to the main Andes arc rocks. The Sr, Nd and Pb isotope ratios show that the source regions of these back-arc basalts are enriched in subducted components that were depleted in the aqueous mobile elements such as Cs, Sr and Ba as a result of prior extractions from the subducted complex below the main arc. Some mafic flows show slightly low (super 206) Pb/ (super 204) Pb and (super 143) Nd/ (super 144) Nd values as well as incompatible trace element ratios similar to southern Patagonia plateau back-arc basalts, suggesting contributions from an EM1 mantle source. Geothermometry and barometry suggest that the basalts crystallized and fractionated small amounts of olivine and spinel at approximately 35km depth at temperatures of 1170-1220 degrees C, at about QFM+0.5 to QFM+1 with 1-2% H (sub 2) O, and then rose rapidly to the surface. The Loncopue graben back-arc basalts are transitional in composition between the South Patagonia back-arc plateau basalts and the Caviahue and Copahue arc volcanoes to the northwest. The EM1 source endmember is possibly the subcontinental lithospheric mantle. Strong variations in incompatible element enrichment and isotopic compositions between closely spaced cinder cones and lava flows suggest a heterogeneous mantle source for the Loncopue graben volcanics.

Studied samples of mafic lavas (4.4-7 wt.% MgO) cover a wide spectrum of potassium levels, and represent magmas considered to be parental to the ultrapotassic leucite-bearing high-K series (HKS, 4-8 wt.% K (sub 2) O) and to shoshonitic (1.5-5%) and subalkaline (1.2) and fluid-depleted signatures suggests that subalkaline magmas originate either from the same source following the exhaustion of amphibole, or from a separate wehrlitic-pyroxenitic (+ or -apatite+ or -carbonate?) assemblage. Our melt inclusion data are consistent with a mixed metasomatic imprint by siliceous potassium-rich and carbonate-rich (carbonatitic) potassium-poor melts. Siliceous melt components dominated in the HKS sources, but a minor group of potassium-poor melt inclusions in HKS samples, with compositions not represented by erupted products, carries trace-element signatures pointing to metasomatism by carbonatite-like melts. The melt inclusions show a general inverse relationship between fO (sub 2) and potassium enrichment, suggesting that primitive potassium-poor magmas are the most oxidized (NNO+0.5), whereas primitive HKS magmas have the lowest oxidation state (NNO-1.6). Mineral chemistry of (near-)liquidus assemblages varies systematically according to the signature of the primary melts from which they crystallized. Calcium contents of Mg-rich olivines and clinopyroxenes are unrelated to the calcium content of the melts but are higher in HKS than in M-LKS samples. Forsterite-rich olivines contain Cr-spinel inclusions with Cr/(Cr+Al) ratios that tend to be higher in M-LKS (0.58-0.80) than in HKS (0.48-0.67) samples. We infer that this parameter, particularly at the more elevated values, is predominantly controlled by the metasomatic veins, and does not necessarily reflect the ('refractory') nature of the pre-metasomatic peridotite component. We surmise that primitive HKS and M-LKS melts of Roccamonfina-Ernici are derived by lower degrees of partial melting of vein lithologies with a stronger metasomatic imprint of the carbonatitic component and more subordinate involvement of pristine wall-rock peridotite than their equivalents of the northern Roman Province. The distinctive HKS and M-LKS sources point to a layered vein-permeated mantle column. Melting possibly occurred in response to a heat pulse induced by exposure to hot asthenospheric mantle, facilitated by post-collisional slab tearing and shallow break-off.

The CCVR is an important physiographic feature separating the Gulf coastal plains from the Altiplano, with pronounced differential relief of more than 1000 m and sloping substrate promoting major edifice failures toward the Gulf of Mexico coastal plain of most of the volcanoes that form that chain. Its structure, composition, and volcanic history diverge significantly from that of the large dominantly andesitic stratovolcanoes that have been the major focus of research efforts in the TMVB. Cofre de Perote volcano is dominated by the successive emplacement of basaltic andesite, andesitic-trachyandesitic to dacitic lava flows and associated breccias erupted through different vents that built a massive low-angle compound shield-like volcano, in contrast to a typical steep stratocone. Despite that apparently stable morphology, repeated edifice collapse has left massive horseshoe-shaped scarps that truncate the eastern side of the edifice. Five major evolutionary stages characterize the growth of this volcano including: 1) emplacement of a multiple-vent dome complex forming the basal structure of Cofre de Perote around 1.3-0.51 Ma; 2) construction of the basal part of the compound shield volcano from at least two main upper-edifice vents and minor flank vents at about 0.42-0.31 Ma; 3) effusion of the summit lavas through multiple vents at 0.25-0.2 Ma; 4) late-stage, large-volume edifice collapse on at least two occasions (ca. 40 ka and ca. 11-13 ka), producing long-runout debris avalanches and debris flows that traveled to the east; and 5) nearly simultaneous eruption of both alkaline and calc-alkaline Pleistocene-to-Holocene monogenetic cones (likely related to regional volcanism) through the flanks of the Cofre de Perote edifice. Long-term factors influencing edifice failure include hydrothermal alteration, increased pore pressure from glacially derived water, extension produced by repetitive volcanism along the chain parallel to the maximum horizontal compression, and perhaps most significantly, construction of the edifice over a sharply eastward-sloping substrate. Evolution of a compound shield volcano like Cofre de Perote reveals that even relatively stable, long-quiescent edifices with a gentle morphology that are considered apparently extinct structures pose a significant hazard to the nearby populated areas, as post-eruptive sector collapses have occurred in recent times (40-11 ka) not associated with contemporaneous volcanic activity.

An. dunhami was identified through retrospective correlation of DNA sequences following misidentification as Anopheles nuneztovari s.l. using available morphological keys for Colombian mosquitoes. That An. dunhami occurs in Colombia and also possibly throughout the Amazon Basin, is of importance to vector control programs, as this non-vector species is morphologically similar to known malaria vectors including An. nuneztovari, Anopheles oswaldoi and Anopheles trinkae. Species identification of An. dunhami and differentiation from these closely related species are highly robust using either DNA ITS2 sequences or COI DNA barcode. DNA methods are advocated for future differentiation of these often sympatric taxa in South America.

Over the past four decades, the North American Breeding Bird Survey and the Christmas Bird Count have shown high rates of population decline ranging from approximately 5 to 12% per year. Regional surveys suggest declines and range retractions in the southern boreal zone. Analyses of historical accounts suggest that the Rusty Blackbird's abundance has been dropping steadily for over a century. A number of hypotheses have been proposed to explain the decline. The species relies on wooded wetlands throughout the year, so loss and degradation of these habitats--particularly in the winter range--is a prime suspect. Blackbird-control programs may have contributed. In recent decades, habitat disturbance, global warming, and environmental contamination in the boreal zone may have taken their toll on breeding populations. In 2005, the International Rusty Blackbird Working Group was formed to develop research efforts toward understanding the mysterious decline. This special section presents the group's research findings--the first on the species' use of breeding and winter habitat, reproductive success, parasite prevalence, patterns of molt, and migratory connectivity. Data on the levels of methylmercury in tissues and the role of timber management on reproductive success are intriguing. We outline research needed for assessment of the roles of various factors in causing the decline of the Rusty Blackbird.

The Neogene sedimentary and fossil record of Amazonia could contain important clues to understanding the evolution of the Amazonian forest. Here, we study the pollen and spore record of two drill cores of the Neogene Solimoes Formation taken in northwestern Brazil, east of the Iquitos Arch. We studied 41 palynological samples and used several techniques to analyze the results, including Unitary Associations, a quantitative biostratigraphic technique, and Multidimensional Scaling Analysis. We describe 109 species, 51 of which are new, and seven new combinations. The biostratigraphic analysis indicates that the age of the Solimoes Formation in the study area is Late Miocene/Early Pliocene. This age is younger than that of nearby sections located west of the Iquitos arch, suggesting that the Iquitos Arch was active during the accumulation of the Solimoes Formation. The pollen/spore assemblages indicate that the Solimoes accumulated in fluvial deposits. We did not find evidence of either marine/tidal-flat deposits or extensive lakes. JF - Palaeontographica.

Placental CRH is involved in an endocrine circuit key to the production of estrogens during pregnancy. CRH induces cortisol production by the maternal and fetal adrenal glands, leading to further placental CRH production. CRH also stimulates the fetal adrenal glands to produce dehydroepiandrostedione sulfate (DHEAS), which the placenta converts into estrogens. There are at least two patterns of maternal circulating CRH across gestation among anthropoids. Monkeys examined to date (Papio and Callithrix) have an early-to-mid gestational peak of circulating CRH, followed by a steady decline to a plateau level, with a possible rise near parturition. In contrast, humans and great apes have an exponential rise in circulating CRH peaking at parturition. To further document and compare patterns of maternal circulating CRH in anthropoid primates, we collected monthly blood samples from 14 squirrel monkeys (Saimiri boliviensis) and ten owl monkeys (Aotus nancymaae) during pregnancy. CRH immunoreactivity was measured from extracted plasma by using solid-phase radioimmunoassay. Both squirrel and owl monkeys displayed a mid-gestational peak in circulating CRH: days 45-65 of the 152-day gestation for squirrel monkeys (mean±SEM CRH = 2,694±276 pg/ml) and days 60-80 of the 133-day gestation for owl monkeys (9,871±974 pg/ml). In squirrel monkeys, circulating CRH declined to 36% of mean peak value by 2 weeks before parturition and then appeared to increase; the best model for circulating CRH over gestation in squirrel monkeys was a cubic function, similar to previous results for baboons and marmosets. In owl monkeys, circulating CRH appeared to reach plateau with no subsequent significant decline approaching parturition, although a cubic function was the best fit. This study provides additional evidence for a mid-gestational peak of maternal circulating CRH in ancestral anthropoids that has been lost in the hominoid lineage. Copyright John Wiley & Sons.

We review the geologic and phylogenetic evidence from Amazonia and compare it with uplift records from the Andes. This uplift and its effect on regional climate fundamentally changed the Amazonian landscape by reconfiguring drainage patterns and creating a vast influx of sediments into the basin. On this "Andean" substrate, a region-wide edaphic mosaic developed that became extremely rich in species, particularly in Western Amazonia. We show that Andean uplift was crucial for the evolution of Amazonian landscapes and ecosystems, and that current biodiversity patterns are rooted deep in the pre-Quaternary.

Our compilation of maximum body size at the ordinal level by sub-epoch shows a near-exponential increase after the K/Pg. On each continent, the maximum size of mammals leveled off after 40 million years ago and thereafter remained approximately constant. There was remarkable congruence in the rate, trajectory, and upper limit across continents, orders, and trophic guilds, despite differences in geological and climatic history, turnover of lineages, and ecological variation. Our analysis suggests that although the primary driver for the evolution of giant mammals was diversification to fill ecological niches, environmental temperature and land area may have ultimately constrained the maximum size achieved.

Theoretical predictions of species density such as those arising from the metabolic theory of ecology hold well at large spatial and temporal scales but are not supported in many communities sampled at a relatively small scale. At these scales ecological factors may be more important than the inherent limits to energy use set by allometric scaling of mass. These factors include the amount of resources available, and the ability of individuals to convert these resources successfully into population growth. While previous studies have demonstrated the limits of macroecological theory in explaining local abundance, few studies have tested alternative generalized mechanisms determining abundance at the community scale. Using an assemblage of forest moth species found co-occurring as caterpillars on a single host plant species, we tested whether species abundance on that plant could be explained by mass allometry, intrinsic population growth, diet breadth, or some combination of these traits. We parameterized life history traits of the caterpillars in association with the host plant in both field and laboratory settings, so that the population growth estimate was specific to the plant on which abundance was measured. Using a generalized least-squares regression method incorporating phylogenetic related-ness, we found no relationship between abundance and mass but found that abundance was best explained by both intrinsic population growth rate and diet breadth. Species population growth potential was most affected by survivorship and larval development time on the host plant. Metabolic constraints may determine upper limits to local abundance levels for species, but local community abundance is strongly predicted by the potential for population increase and the resources available to that species in the environment.

The species represents one of the earliest and best characterized unequivocal occurrences of the multivincular ligament in the superfamily Pterioidea. The silicified material provides a wealth of information on the morphology of inadequately known Paleozoic pterioideans, including hitherto undescribed aspects of the larval shell, auricular sulcus, muscle scars, and dental ontogeny. The discovery of the condyle-fossa complex on the anteroventral shell margin, a feature previously undescibed in Bivalvia, raises the question of the homology and taxonomic significance of the problematic subumbonal ridge-like structures in Pterioidea. In life, C. galtarae was probably an epifaunal right-pleurothetic bivalve, byssally attached to hard or raised flexible substrata. In addition to C. galtarae, another new species, C. nadkevnae, is placed in Cassiavellia.

We assess the influence of inherited structural fabrics, changes in basin geometry, erosional denudation, and the characteristics of the tectonic stress field with respect to the evolution of the structural styles of the deformation front in the Eastern Cordillera. Detailed structural and geomorphic mapping of an area of approximately 5000 km (super 2) , analysis of seismic-reflection profiles, cross-section balancing, tectonic stress-field indicators, and new apatite fission-track data are used to characterize the partitioning of Late Cenozoic deformation in the eastern foothills of the Eastern Cordillera of Colombia. During the late Miocene-Pliocene, in the Eastern Cordillera, deformation migrated from inverted master normal faults to low-elevation, low-amplitude structures in the foreland. However, this shift in the locus of deformation was not spatially uniform. The deformation front is wider in a northern sector of the Cordilleran foothills, where sedimentary units are thicker, and shortening is perpendicular to the structures. This shortening direction is identical to the direction of the greatest horizontal stress S (sub Hmax) as seen in borehole breakouts. During the late Miocene-Pliocene, basement ranges are passively uplifted by younger, more frontal thrusts. The eastern foothills of the Eastern Cordillera thus reveal a complex combination of factors responsible for the structural styles and partitioning of active deformation in an inversion orogen. Over time, the most important factor changes, from the role of inherited structural fabrics to the geometries of basin fills.

We also analysed Placentia Bay demographic data and shipping records to look for congruent patterns with genetic analyses.Results Demographic data and surveys suggested that C. maenas populations are established and were in Placentia Bay for several years (c. 2002) prior to discovery. Genetic data corroboratively suggested central-western Scotian Shelf populations (e.g., Halifax) as the likely source area for the anthropogenic introduction. These Scotian Shelf populations were within an admixture zone made up of genotypes from both the earlier (early 1800s) and later (late 1900s) introductions of the crab to the NWA from Europe. Placentia Bay also exhibited this mixed ancestry. Probable introduction vectors included vessel traffic and shipping, especially vessels carrying ballast water.Main conclusions Carcinus maenas overcame considerable natural barriers (i.e., coastal and ocean currents) via anthropogenic transport to become established and abundant in Newfoundland. Our study thus demonstrates how non-native populations can be important secondary sources of introduction especially when aided by human transport. Inference of source populations was possible owing to the existence of an admixture zone in central-western Nova Scotia made up of southern and northern genotypes corresponding with the crab's two historical introductions. Coastal vessel traffic was found to be a likely vector for the crab's spread to Newfoundland.

Allee effects, positive relationships between fitness and density or number of conspecific individuals, can play a substantial role in determining the time lag between initial introduction and invasive spread and can produce genetic patterns in invading populations that can be interpreted to learn about factors affecting invasion mechanisms.2.We examined the distribution of genetic variation in the invasive wetland grass Phragmites australis in the Chesapeake Bay, USA. We used microsatellite analysis to examine the reproductive mode (clonal vs. seed) by which the invasive haplotype of P. australis has spread and the distribution of genetic variation within and among brackish wetlands in nine subestuaries of the Chesapeake Bay. Watersheds associated with the subestuaries were dominated by forests, anthropogenic development or mixed forests and development.3. Our results suggest that the invasive haplotype of P. australis has spread primarily sexually by seed, rather than clonally, and genetic diversity of patches within subestuaries increased while genetic similarity decreased with increasing development in the surrounding watershed.4. This suggests a pattern whereby greater genetic diversity of patches may promote more rapid spread due to recruitment of multiple seedlings into a disturbed patch.5.

AN - 759878107; 20650882 AB - Cheetahs and certain other felids consistently ejaculate high proportions (≥ 60%) of malformed spermatozoa, a condition known as teratospermia, which is prevalent in humans. Even seemingly normal spermatozoa from domestic cat teratospermic ejaculates have reduced fertilizing capacity. To understand the role of sperm metabolism in this phenomenon, we conducted a comparative study in the normospermic domestic cat versus the teratospermic cat and cheetah with the general hypothesis that sperm metabolic function is impaired in males producing predominantly pleiomorphic spermatozoa. Washed ejaculates were incubated in chemically defined medium containing glucose and pyruvate. Uptake of glucose and pyruvate and production of lactate were assessed using enzyme-linked fluorescence assays. Spermatozoa from domestic cats and cheetahs exhibited similar metabolic profiles, with minimal glucose metabolism and approximately equimolar rates of pyruvate uptake and lactate production. Compared to normospermic counterparts, pyruvate and lactate metabolism were reduced in teratospermic cat and cheetah ejaculates, even when controlling for sperm motility. Rates of pyruvate and lactate (but not glucose) metabolism were correlated positively with sperm motility, acrosomal integrity, and normal morphology. Collectively, our findings reveal that pyruvate uptake and lactate production are reliable, quantitative indicators of sperm quality in these two felid species and that metabolic function is impaired in teratospermic ejaculates. Furthermore, patterns of substrate utilization are conserved between these species, including the unexpected lack of exogenous glucose metabolism. Because glycolysis is required to support sperm motility and capacitation in certain other mammals (including dogs), the activity of this pathway in felid spermatozoa is a target for future investigation.

With respect to gradual phyletic change, we know that randomly generated sequences may exhibit characteristics of a "trend"; apparent patterns, therefore, must be interpreted with caution. Furthermore, even when the claim of a gradual trend can be statistically justified, interpretation of the underlying mechanisms may be challenging. Given that we can observe populations changing rapidly over tens or hundreds of years, it is now more difficult to explain instances of geologically gradual (as opposed to punctuated) change. Here we describe morphologic change in two bivalve lineages from the late Miocene Lake Pannon. We evaluate change according to the model-based methods of Hunt. Both lineages exhibit size increases and shape changes over an interval of nearly 4 million years. Size and two shape variables in the conjungens lineage are best fit by a model of directional evolution; remaining shape variables mostly conform to unbiased random walks. Body-size evolution in the diprosopum lineage is also significantly directional but all shape variables are best fit by the unbiased random walk model; the small number of sampling intervals available for this lineage (n = 6) makes determination of the actual pattern more difficult. Model-fitting results indicate that the parallel trajectories of increasing log shell height over time in the two lineages can be accounted for by an underlying trend shared by both lineages, suggesting that the size increases may be a shared response to the same cause. The pace of phenotypic change, measured as Lynch's Delta , is slower than the neutral expectation for all size and shape traits. Our examples illustrate well the paradox of gradualism; the sequences exhibit significant directional morphological evolution, but rates of change as measured over the long-term are apparently too slow for directional selection or even drift to be the cause. Viewing long-term phenotypic evolution in terms of populations tracking peaks on adaptive landscapes is useful in this context. Such a view allows for intervals of directional selection (during times of peak movement--resulting in the overall trends we can detect) interspersed with intervals of stasis (during times of peak stability--resulting in overall changes that appear to proceed more slowly than the neutral expectation). The paradox of gradualism thus reduces to (1) peak movements and their drivers, which are not restricted in rate as are population-genetic drivers, and (2) the maintenance of stasis, on which no consensus exists. We can identify no environmental parameter in the central European Neogene that exhibits consistent change across the interval of gradual morphologic change. It may be that in Lake Pannon the long-term persistence of generally ameliorating conditions (plentiful resources and habitat space, few predators or competitors) resulted in geologically slow but consistent peak shifts, which in turn facilitated size increase and shape change in these lineages.

The PDF technique recently has been applied in the structural characterization of several disordered environmental minerals, such as ferrihydrite and imogolite. In this study, we used PDF analysis to investigate the structures of nanophase manganese (Mn) oxides. Mn-oxides, including both layered and tunnel structures, are strong oxidants and extraordinary metal sorbents in nature. Naturally-occurring Mn-oxides often have poor crystallinity as determined via XRD, and neither XRD nor EXAFS techniques are able to fully interpret, or even differentiate, their structures. For example, amorphous todorokite (3 X 3 tunnel structure) and birnessite (layered structure) cannot be differentiated by XRD and EXAFS if they are so disordered that 7 or 10 Aa d-spacing is not observed. delta -MnO) , polymeric MnO (sub 2) and biogenic Mn-oxides are most often used as analogs to investigate the environmental behaviors of natural poorly crystalline Mn-oxides. Our PDF results indicate that delta MnO (sub 2) , polymeric MnO (sub 2) and a biogenic Mn-oxide sample are layered structures with nearly hexagonal symmetry. The particle size and shape are refined during the structural modeling for the PDF simulation. The best model accurately allowing simulation of the PDFs is a monoclinic structure with the C2/m space group using a disk-like shape factor with a high degree of stacking disorder. These results help in understanding the reactivity and mineralogy of several naturally-occurring Mn-oxide minerals.

The group was asked to consider collaborative science opportunities both without change to either rover, as well as with some change allowed. The analysis started with analysis of shared and separate objectives. We concluded that the two rovers have two high priority shared objectives that could, in fact, form the basis of highly significant collaborative exploration activity: 1) At a site interpreted to contain evidence of past environments with high habitability potential and with high preservation potential for physical and chemical biosignatures, they could evaluate paleo-environmental conditions, assess the potential for preservation of biotic and/or prebiotic signatures, and search for possible evidence of past life and prebiotic chemistry, and 2) Collect, document, and package in a suitable manner, a set of samples sufficient to achieve the proposed scientific objectives of a future sample return mission. Furthermore, the payloads proposed for these two rovers complement one another, and naturally lend themselves to cooperative exploration. It is possible to define a list of possible opportunities to add value through cooperation in a 2-rover mission that can be prioritized on the basis of increased science and expected implementation difficulty. Some of these ideas could be implemented with little or no change to the design of either rover, but for others significant change would be needed. Certain operational scenarios are implied in order to achieve the value indicated. We recognize, however, that achieving cooperative science would imply making certain compromises by each rover, the most important of which include: 1) less time available for pursuing each rover's independent objectives, 2) the need to share a landing site that may not be optimized for either rover, 3) and cost associated with some hardware modifications.

Crews on future long duration missions will likely have the opportunity to plan traverses in real-time based on previous science-driven EVAs, reconnaissance sorties, and exploration strategies tested during analog missions on Earth. Right now mission managers are interested in best enabling science during future missions by learning the strategies and philosophies used by terrestrial field geologists. For example, the metrics acquired on all aspects of geological field traverses on Earth can be used as guidelines in planning future sorties staged from a planetary outpost. Multi-year, reconnaissance field mapping projects carried out by the Geological Survey of Canada (GSC) in remote areas of the Arctic Islands provide a unique opportunity to record the results of science-driven field traverses on a large scale. The targeted objectives for the field season are defined using remote predictive maps constructed from existing maps of bedrock geology and topography; LANDSAT, GEOEYE and SPOT 5 images; air photographs; and geophysical data. Once on site, field mapping teams rely on a combination of digital mapping technologies and traditional field methods to record observations and measurements, all of which are integrated at Base Camp into a Geographic Information System (GIS). The resulting databases uniquely record each step in the planning, execution, and analysis of geological transects carried out by field teams over a period of several weeks. In this paper we present a preliminary analysis of the metrics recorded during 200 geological foot traverses spread over an area of 4000 km (super 2) from the GSC Minto Base Camp located on Victoria Island, Northwest Territories (N71.617787 degrees W115.438987 degrees ). Over the course of the summer field season, 21 geologists carried out an average of 8 field traverses a day, recording data at over 2000 ground stations within the targeted study area. Particular attention is given in the paper to the (1) logistics and planning of reconnaissance vs. detailed mapping traverses carried out during the field season, (2) the decision-making process and impact of real time changes in the field, and (3) lessons learned for future exploration missions on planetary surfaces.

Experimental analysis of prey selection by Natica unifasciata AN - 1033533625; 2012-073895 AB - Analyses of molluscan death assemblages from the eastern Pacific coastline of Panama indicate that naticid predation is concentrated among particular prey species, regardless of their underlying abundance. One explanation for this observation is that naticid gastropods have a selective feeding behavior. Laboratory experiments were therefore carried out to investigate aspects of prey choice by the locally abundant Natica unifasciata. One series of experiments (with replacement) tested not only the preference of predators for one of three prey genera (Iliochione, Protothaca, and Juliacorbula), but also the consequences of varying prey abundance on their consumption. Prey species were represented by either the same number of individuals (5 specimens) or with varied abundance (species having either 8, 5, or 2 specimens) in each treatment. A second experiment was conducted to determine the sequence by which Natica selected prey as they depleted each prey resource (without replacement), and included the prey genera Carditamera, Mactrotoma, Florimetis, Iliochione, Protothaca, and Juliacorbula. In simple prey-choice experiments Natica unifasciata overwhelmingly preferred consumption of Protothaca, regardless of abundance. Where all taxa were evenly abundant (5 specimens each per tank) Protothaca would be consumed in approximately 95% of observations, and even when rare (2 specimens per tank) Protothaca would be the prey consumed in approximately 85% of cases. The prey sequence experiment (without replacement) showed that Natica consumed Flormimetis earliest, followed by Mactrotoma and Protothaca, with successively less frequent attacks on Iliochione and Carditamera. These results confirm our observations from beach collections, that naticid feeding behavior is highly selective towards particular prey species. Natica unifasciata shows a preference for bivalves of moderate size (<25 mm), with thin shells, and minor surface sculpture. An absence of incomplete drill holes among surviving prey specimens hints that the selection of prey occurs before they are encountered physically, possibly through water-borne chemical cues.

Prey and predator body size and stereotypy in naticid drill-hole location AN - 1033533482; 2012-073896 AB - Selectivity of naticid predators with respect to drill hole location is well known, but the relationship between prey and predator size and drilling behavior is not as well documented. In this study we integrate results from laboratory experiments with material collected at local beaches to examine the affects of prey and predator body size on the location and type of drilling behavior. We focus on three locally abundant species of venerid bivalve, Iliochione subrugosa, Lirophora obliterata, and Protothaca asperrima. Experiments involved testing for selectivity by Natica unifasciata on multiple prey species, along with controlled generation of drilled valves from combinations of predator and prey with varying body size. Additional shells were obtained from bulk sampled high-tide drift on beaches along the eastern Pacific coastline of Panama. We also compare the stereotypy of drill hole location in these taxa to morphologically similar species Panchione mactropsis and Lirophora falconensis from the late Miocene Gatun Formation of Panama. The spatial distribution of drill holes was determined using landmark analysis, and shell length and hole diameter were used as proxies of shell size and predator size, respectively. We found that, independent of sampling site, larger shells (Lirophora >12 mm, Iliochione and Protothaca >20 mm) of all three species were attacked more often on the antero-ventral margin, whereas smaller specimens were drilled most commonly close to the umbo. The anterior and posterior shell margins that correspond with the position of the adductors muscles present the lowest drilling intensity. This spatial distribution is most strongly expressed in the thick-shelled Iliochione. Thinner Protothaca were most commonly drilled in a very tightly clustered area around the umbo, while drilling was scattered across the smaller and more heavily ribbed Lirophora. These results highlight the plasticity in feeding behavior of naticids when encountering prey of varying body size and morphology.

The team has an award from the National Science Foundation Program, Assembling the Tree of Life. The five living classes of echinoderms are Asteroidea, Crinoidea, Echinoidea, Holothuroidea, and Ophiuroidea. However, these classes represent a shadow of both the full morphological disparity and diversity of Lower Paleozoic echinoderms that includes as many as 21 classes. Phylogenetic analysis of living echinoderms remains challenging. Moreover a complete echinoderm evolutionary tree will have to incorporate all echinoderm lineages and key outgroups to link echinoderms into the broader tree of life. The project is organized with the following working groups: genomics, morphology, informatics, and outreach. Our goals include genomic sampling of numerous exemplars among the five living echinoderm classes, integration of genomic and morphologic data of living echinoderms with Cenozoic and Mesozoic fossil data, definition of Paleozoic clades, and positioning sister group relationships among the stem group echinoderm clades. Homology among distinctive echinoderm groups must be established first despite diverse nomenclature. Data will be analyzed with multiple hypotheses of outgroups and characters by teams of echinoderms specialists. Collaborations are welcome. Outreach will include videos and broadcasts about marine exploration and applications of fundamental biological research across the biomedical sciences. Also co-authors on this abstract, Tare, W. I.

Additionally, such assemblage-level data may be used to interpret spatial (e.g., latitudinal) or temporal (e.g., evolutionary) trends in predation pressure. Surprisingly, therefore, few studies have investigated how sampling methodology, local environmental conditions, or taphonomic processes can influence these records. We investigate these issues using replicate-collected bulk samples of shells from beaches along the eastern Pacific and Caribbean coastlines of Panama and Colombia. In a general sense, predation intensity among infaunal bivalves appears higher in the eastern Pacific (mean of 14.4%) than that of the Caribbean region (mean of 7.4%). However, samples show considerable variation within both regions (6-30 % in the eastern Pacific; 1-18 % in the Caribbean). Two principle factors that may be responsible for this are: 1) local-scale variations in environment from one beach (shore-face environment) to another; and 2) beach-to-beach differences in taphonomic processes (caused by wave-energy, sorting, and accumulation rate). Local environmental conditions (e.g., substrate or salinity) can influence the community roster such that it contains taxa either favored or avoided by locally occurring predators, species with effective defense mechanisms, or taxa too small or large to be easily preyed upon. Wave-energy, tidal height, and local beach morphology will influence not only the "shelliness" of the beach, but also the degree of taphonomic damage and size sorting a beach sample may exhibit and in doing so may skew estimates of bored individuals within assemblages. Considerable within-habitat variation, as indicated by differences in predation intensity between replicate samples, presumably results from differential sorting of shells along the length of individual beaches. The results have implications not only for sample design in assemblage-level predation studies but also in the interpretation of spatial and temporal variations in predation intensity.

The melanges testify to collisional emplacement of subduction assemblages. Differences in PTtX evolution argue for petrogenesis in distinct events. Here, we analyze serpentinites to assess protoliths, petrogenesis, deformation, and the effects of serpentinization. Much serpentinite from north and south of the MFZ is sheared and recrystallized to antigorite schist, which lacks textural or mineralogical relics of peridotite. Magnetite is the most common accessory mineral (but less so in foliated rocks), and in order of relative abundance, magnesite and/or dolomite, talc, chlorite, chromite and secondary diopside. Only trace lizardite and no chrysotile is found. Mn-ilmenite, Ni-sulfides, FeNi alloys, and andradite are rarest. Less-tectonized or -altered samples contain relict pyroxene grains, pseudomorphs of exsolved Opx and Cpx grains (bastite with relict Al-rich Cpx: to 8 wt% Al (sub 2) O (sub 3) ). Textures, minerals and bulk compositions suggest harzburgite was the most common protolith, followed by lherzolite and rare dunite; however, the abundances of Mg-Si-Al in the serpentinites are controlled by antigorite modes and compositions, complicated by fluid-produced talc and carbonate minerals. Relatively unserpentinized samples retain Ol + Cpx + Sp + or - Opx. Some with high modal Cpx indicate lherzolite protoliths. However, Cpx is LREE depleted with MORB-like Sr-Nd patterns, indicating significant melt extraction. The Cpx may have formed by refertilization of harzburgite with fluids derived from depleted mantle. Pyroxene thermometry yields T = 900-1000 degrees C at P = 10-20 kbar. These rocks also display coexisting Atg-Ol pairs. Their Fe-Mn-rich Ol grain boundaries indicate local hydrous equilibration at 500-600 degrees C. Antigorite serpentinite is consistent with mantle wedge hydration above a subduction channel. However, variations of modes of talc, carbonate, chlorite, and magnetite show important influences of subduction zone fluids in modifying peridotite compositions. Relic phases remain the best indicators of protolith identity. These argue for complex, reprocessed mantle peridotites for both melange belts.

Here we describe changes in plants, vertebrates, paleosols and carbon isotopes that occurred across the PETM in the southeastern Bighorn Basin (paleo-lat 49 N). The uppermost 15 m of Fort Union Fm. beneath the PETM has typical latest Paleocene biotas and carbon isotopic values, though there are yellow and red mudstone paleosols that are unusual compared with the earlier Paleocene. The base of the CIE (negative shift of 3-5ppm) occurs in the first laterally persistent mudstone paleosol containing CaCO (sub 3) nodules, which also preserves the Wa0 vertebrate fauna characteristic of the PETM. The overlying 5-8 m has 1-2 variegated paleosols, Wa0 vertebrates, and a unique flora dominated by legumes and other taxa not present in the Paleocene or post-PETM. The approximately 20 m of section above these lowest red paleosols has abundant cut-and-fill deposits and poorly developed paleosols with large CaCO (sub 3) nodules; carbon isotopes indicate this is the plateau phase of the carbon isotope excursion coincident with the PETM. Wa0 mammals are abundant, and floras of unusual composition are documented from six sites. In the succeeding approximately 20 m of section carbon isotope values become more positive again, paleosols are thick, purple-red, and lack CaCO (sub 3) nodules, and both fauna and flora take on a more standard Eocene composition. We interpret PETM changes as follows. Floodplains became better drained with the onset of the event, or possibly just before it, because of seasonal precipitation and/or higher temperatures. Biotic change was rapid, occurring in <5 m of section (<20 ky). The middle PETM had highly unstable channels, reflecting increased rates of erosion caused by seasonal precipitation, and biotas were dry tropical. The PETM concluded with a phase of wetter climate, more stable floodplains, and warm temperate biotas. Coincident changes in fauna, flora and paleosols across the PETM suggest that all three were being forced by global environmental change. Drying in our field area is not predicted by climate models of the PETM and raises the possibility that anthropogenic warming may have unexpected effects on precipitation amount and seasonality in the interior of North America.

Each organization likely operates with a separate data platform, perhaps in response to different data sets, and responds to a different user community, whether internal, the scientific community, or the public. Apart from the technical challenges of data integration, the conceptual challenges of building a single database to respond to multiple agency and constituency agendas can be the greatest obstacle. We illustrate these challenges by examining the samples and data held collectively by the U.S. Antarctic Meteorite Program, a joint venture of NSF, NASA and the Smithsonian Institution. NSF is responsible for the collection of Antarctic meteorites through a grant to CWRU. Field photographs of each meteorite are not databased, while field locales are mapped using ArcGIS. The ArcGIS mapping project primarily benefits field expeditions, allowing quick visualization of productive field locales to plan future expeditions, and meteorite classifiers, allowing visualization of potential pairing groups. NASA is responsible for short-term curation of Antarctic meteorites at Johnson Space Center. In addition to specimens, JSC holds data on current samples and allocation histories in a FoxPro database primarily for use by curators and an allocation committee. JSC also hosts a web-based search engine on the current availability of samples and meteorite descriptions. This database, although publicly accessible, is primarily used by the scientific community. The Smithsonian is responsible for classification and long-term curation. In addition to specimens, data is held in EMu with a subset available through a web-based search engine. EMu, a relational database primarily used internally by museums, is designed to integrate collections information across disciplines. As such, it is not tailored to the geologic community and the primary audience for the search engine is the public, not the scientific community. Although long-term integration of Antarctic meteorite data is desirable, it presents both a logistical challenge and, more importantly, a distinct set of audiences which no single database structure is likely to satisfy.

Antarctic Meteorite Program ER - TY - JOUR T1 - Understanding ecosystem retrogression AN - 1015459115; 2012-048952 AB - Over time scales of thousands to millions of years, and in the absence of rejuvenating disturbances that initiate primary or early secondary succession, ecosystem properties such as net primary productivity, decomposition, and rates of nutrient cycling undergo substantial declines termed ecosystem retrogression. Retrogression results from the depletion or reduction in the availability of nutrients, and can only be reversed through rejuvenating disturbance that resets the system; this differs from age-related declines in forest productivity that are driven by shorter-term depression of nutrient availability and plant ecophysiological process rates that occur during succession. Here we review and synthesize the findings from studies of long-term chronosequences that include retrogressive stages for systems spanning the boreal, temperate, and subtropical zones. Ecosystem retrogression has been described by ecologists, biogeochemists, geologists, and pedologists, each of which has developed somewhat independent conceptual frameworks; our review seeks to unify this literature in order to better understand the causes and consequences of retrogression. Studies of retrogression have improved our knowledge of how long-term pedogenic changes drive shorter-term biological processes, as well as the consequences of these changes for ecosystem development. Our synthesis also reveals that similar patterns of retrogression (involving reduced soil fertility, predictable shifts in organismic traits, and ecological processes) occur in systems with vastly different climatic regimes, geologic substrates, and vegetation types, even though the timescales and mechanisms driving retrogression may vary greatly among sites. Studies on retrogression also provide evidence that in many regions, high biomass or "climax" forests are often transient, and do not persist indefinitely in the absence of rejuvenating disturbance. Finally, our review highlights that studies on retrogressive chronosequences in contrasting regions provide unparalleled opportunities for developing general principles about the long-term feedbacks between biological communities and pedogenic processes, and how these control ecosystem development.

In order to understand and model the consequences of these dynamic land-use changes for regional water cycles, the response of soil hydraulic properties to forest disturbance and recovery has to be quantified. At a site in the Brazilian Amazonia, we annually monitored soil infiltrability and saturated hydraulic conductivity (K sub(s)) at 12.5, 20 cm, and 50 cm soil depth after manual forest conversion to pasture (year zero to four after pasture establishment), and during secondary succession after pasture abandonment (year zero to seven after pasture abandonment). We evaluated the hydrological consequences of the detected changes by comparing the soil hydraulic properties with site-specific rainfall intensities and hydrometric observations. Within one year after grazing started, infiltrability and K sub(s) at 12.5 and 20 cm depth decreased by up to one order of magnitude to levels which are typical for 20-year-old pasture. In the three subsequent monitoring years, infiltrability and K sub(s) remained stable. Land use did not impact on subsoil permeability. Whereas infiltrability values are large enough to allow all rainwater to infiltrate even after the conversion, the sudden decline of near-surface K sub(s) is of hydrological relevance as perched water tables and overland flow occur more often on pastures than in forests at our study site. After pasture abandonment and during secondary succession, seven years of recovery did not suffice to significantly increase infiltrability and K sub(s) at 12.5 depth although a slight recovery is obvious. At 20 cm soil depth, we detected a positive linear increase within the seven-year time frame but annual means did not differ significantly. Although more than a doubling of infiltrability and K sub(s) is still required to achieve pre-disturbance levels, which will presumably take more than a decade, the observed slight increases of K sub(s) might already decrease the probability of perched water table generation and overland flow development well before complete recovery.

The pH optima of eight hydrolytic enzymes involved in the cycles of carbon, nitrogen, phosphorus, and sulfur, were assessed in a series of tropical forest soils of contrasting pH values from the Republic of Panama. Assays were conducted using 4-methylumbelliferone-linked fluorogenic substrates in modified universal buffer. Optimum pH values differed markedly among enzymes and soils. Enzymes were grouped into three classes based on their pH optima: (i) enzymes with acidic pH optima that were consistent among soils (cellobiohydrolase, ?-xylanase, and arylsulfatase), (ii) enzymes with acidic pH optima that varied systematically with soil pH, with the most acidic pH optima in the most acidic soils (-glucosidase, ?-glucosidase, and N-acetyl-?-glucosaminidase), and (iii) enzymes with an optimum pH in either the acid range or the alkaline range depending on soil pH (phosphomonoesterase and phosphodiesterase). The optimum pH values of phosphomonoesterase were consistent among soils, being 4 to 5 for acid phosphomonoesterase and 10 to 11 for alkaline phosphomonoesterase. In contrast, the optimum pH for phosphodiesterase activity varied systematically with soil pH, with the most acidic pH optima (3.0) in the most acidic soils and the most alkaline pH optima (pH 10) in near-neutral soils. Arylsulfatase activity had a very acidic optimum pH in all soils (pH 3.0) irrespective of soil pH. The differences in pH optima may be linked to the origins of the enzymes and/or the degree of stabilization on solid surfaces. The results have important implications for the interpretation of hydrolytic enzyme assays using fluorogenic substrates.

Embryonic size should also have direct effects upon the forces that govern swimming, a behavior common to early larval development in the plankton. If swimming is ecologically important, early larvae may need to perform to a certain "standard", or threshold of speed and/or stability. The existence of performance standards in early development could therefore act to constrain the evolution of egg size and the evolution of development. Here we present the key parameters that characterize the upward swimming speed of ciliated spheroidal larvae moving at very low Reynolds numbers. The dependence of maximum supported mass upon larval size, and the independence of neutral-weight swimming speed from size, lead to hypotheses about scaling of swimming speed with size. Experimental studies with thirteen broadcast-spawning planktotrophs demonstrate that free-living embryonic swimmers in all of these species conform to a strong negative scaling of density with size that offsets increases in mass with increasing size. This trend suggests that swimming ability is broadly under selection in early development. In experimental studies and in a hydrodynamic model of larval swimming, the performance of trochophore larvae provides support for our hypothesized scaling relationships, and also for the concept of a standard in swimming speed. Echinoid blastulae, however, show relationships between speed and size that are not predicted by our scaling arguments. Results for echinoids suggest that differences in ciliary tip speed, or possibly in spatial density of cilia over the blastula's surface, result in significant differences in species' performance. Strong phyletic differences in the initial patterning and growth of structures used for swimming thus appear to cause significant differences in the relationship of swimming ability with embryo size.

Geological and geochronological data from this region indicate that the metamorphic basement consolidated during the Orinoquiense ( approximately 1.0 Ga) and Caparonensis ( approximately 0.47 Ga) orogenic events. The latter formed part of a proto-Andean orogen that extended from Venezuela to northern Argentina. Interactions between Laurentia and the peri-Amazonian proto-Andes during Late Proterozoic-Paleozoic times, is supported by geological, geochronological, isotopic data and by faunal affinities of the sedimentary sequences overlying the basement complex. This interaction may have included possible terrane transfer between Laurentia and Amazonia. Geological, tracer-isotopic and geochronological data suggest that a fragment of the proto-Andean orogen is presently located at the southern end of Mexico (Oaxaquia). The transfer of Oaxaquia from the northern termination of the proto-Andes, most likely occurred in late Paleozoic time and was left attached to N. America upon the disaggregation of Pangea.

No major modern rivers flow into this canyon, thus ruling out principal fluvial control on the present geometry of this feature. Recently acquired multibeam sonar bathymetry data have provided insight into the three-dimensional geometry of this outstanding feature that disrupts the seafloor relief. In addition, seismic reflection data provide images of the internal structure of the canyon's subsurface. In this study, we describe the morphology of the Aguja Canyon along a series of transects, interpret the structure under the canyon, and discuss possible geologic processes that played a role during its formation and modification. Seismic data indicate that incision of the canyon's inner reach is the result of recent motion along the western termination of the active Oca strike-slip fault. Relief in the middle reach may be predominantly controlled by sedimentary processes (erosion, infilling and lateral thalweg migration). In the past, however, the middle reach may have been tectonically controlled. The outer reach appears to be the combined result of tectonics, sedimentary process and mud-diapiric intrusions. We conclude that the Aguja Canyon is predominantly a tectonic feature that accommodates shallow transpressive stresses as dislocation of the seafloor.

An unlithified ruditic deposit of probable Quaternary age exhibiting tectonic deformation crops out at the Riofrio site. It consists of a series of debris slope layers that make up a colluvial cone. The documented deformation in this outcrop is characterized by a backtilting of the sequence to the NE and by the presence of apparent dip-slip faulting. This is thought to be the side view expression of predominantly strike-slip movement. A minimum magnitude (Mw) of 6.4 was estimated for an identified faulting event based on outcrop measurements of fault displacement.

Extensional deformation is recorded in the 260 km-wide, fan-shaped Plato-San Jorge basin by a 2-8 km thick, shallowing-upward and almost entirely fine-grained, upper Eocene and younger sedimentary sequence. The simultaneous initiation of shortening in the Cesar-Rancheria basin is documented by Mesozoic strata placed on to lower Eocene syntectonic strata (Tabaco Formation and equivalents) along the northwest-verging, shallow dipping (9-12 degrees to the southeast) and discrete Cerrejon thrust. First-order subsidence analysis in the Plato-San Jorge basin is consistent with crustal stretching values between 1.5 and 2, also predicted by the rigid-body rotation of the Santa Marta massif. The model predicts about 100 km of right-lateral displacement along the Oca fault and 45 km of left-lateral displacement along the Santa Marta-Bucaramanga fault. Clockwise rotation of a rigid Santa Marta massif, and simultaneous Paleogene opening of the Plato-San Jorge basin and emplacement of the Cerrejon thrust sheet would have resulted in the fragmentation of the Cordillera Central-Santa Marta massif province. New U/Pb ages (241+ or -3 Ma) on granitoid rocks from industry boreholes in the Plato-San Jorge basin confirm the presence of fragments of a now segmented, Late Permian to Early Triassic age, two-mica, granitic province that once spanned the Santa Marta massif to the northernmost Cordillera Central.

Three magnetic components were identified in this study. A first component has a direction parallel to the present magnetic field and was uncovered in all units (D=352, I=25.6, k=57.35, a95=5.3, N=12). A second component was isolated in Cretaceous limestone and Jurassic volcaniclastic rocks (D=8.8, I=8.3, k=24.71, a95=13.7, N=6), and it was interpreted as of Early Cretaceous age. In Jurassic sites with this component, Early Cretaceous K-Ar ages obtained from this and previous studies are interpreted as reset ages. The third component was uncovered in eight sites of Jurassic volcaniclastic rocks, and its direction indicates negative shallow to moderate inclinations and northeastward declinations. K-Ar ages in these sites are of Early (196.5+ or -4.9 Ma) to early Late Jurassic age (156.6+ or -8.9 Ma). Due to local structural complexity and too few Cretaceous outcrops to perform a reliable unconformity test, we only used two sites with (1) K-Ar ages, (2) less structural complexity, and (3) reliable structural data for Jurassic and Cretaceous rocks. The mean direction of the Jurassic component is (D = 20.4, I = -18.2, k = 46.9, a95 = 5.1, n = 18 specimens from two sites). These paleomagnetic data support previous models of northward along-margin translations of Grenvillian-cored massifs. Additionally, clockwise vertical-axis rotation of this massif, with respect to the stable craton, is also documented; the sense of rotation is similar to that proposed for the Perija Range and other ranges of the southern Caribbean margin. More data is needed to confirm the magnitudes of rotations and translations.

U-Pb detrital zircon geochronology for provenance analysis was carried out on meta-sedimentary rocks of the Etpana formation and metamorphic boulders found within a nearby Tertiary conglomerate, including high-pressure rocks in the Colombian Caribbean. All samples have similar age populations, suggesting that they share a relatively common source and paleogeography. Prominent age peaks include Meso and Paleoproterozoic ages of ca. 1624 Ma and 1315 Ma, Cambrian to Neoproterozoic ages of ca. 630 Ma, 580 Ma and 547 Ma, and less abundant Jurassic and Permian ages of ca. 270 Ma and 160 Ma, which indicate that the South American margin is a major source for the sedimentary protoliths. There are also remnants of younger Cretaceous allocthonous Caribbean arc input at ca. 90-70 Ma. The deposition and metamorphism of these units records the ongoing Late Cretaceous continental subduction of the South American margin within the Caribbean intra-oceanic arc-subduction zone. This gave way to an arc-continent collision between the Caribbean and the South American plates, and sediments with continental signatures were incorporated into the subduction channel and the accretionary wedge. As convergence continued, sediments derived from a mix of South American and arc sources were deposited and included in the collisional wedge up until <71 Ma.

Selected whole rock geochemistry, Nd-Sr isotopes and detrital zircon geochronology were obtained in metabasic and metasedimentary rocks from the Santa Marta and San Lorenzo Schists in northernmost Colombia. Trace element patterns are characterized by primitive island arc and MORB signatures. Similarly initial (super 87) Sr/ (super 86) Sr-epsilon (sub Nd) isotopic relations correlate with oceanic arcs and MORB reservoirs, suggesting that the protoliths were formed within a back-arc setting or at the transition between the inta-oceanic arc and the Caribbean oceanic crust. Trace element trends from associated metasedimentary rocks show that the provenance was controlled by a volcanic arc and a sialic continental domain, whereas detrital U/Pb zircons from the Santa Marta Schists and adjacent southeastern metamorphic units show Late Cretaceous and older Mesozoic, Late Paleozoic and Mesoproterozoic sources. Comparison with continental inland basins suggests that this arc-basin is allocthonous to its current position, and was still active by ca. 82 Ma. The geological features are comparable to other arc remnants found in northeastern Colombia and the Netherlands Antilles. The geochemical and U/Pb detrital signatures from the metasedimentary rocks suggest that this tectonic domain was already in proximity to the continental margin, in a configuration similar to the modern Antilles or the Kermadec arc in the Pacific. The older continental detritus were derived from the ongoing Andean uplift feeding the intra-oceanic tectonic environment. Cross-cutting relations with granitoids and metamorphic ages suggest that metamorphism was completed by ca. 65 Ma.

Two mylonitic and orthogneissic granitoid suites have been recognized in the northeastern segment of the Sierra Nevada de Santa Marta, the lower Magdalena basin and the Guajira Serranias, within the Caribbean region of Colombia. For the Santa Marta region U/Pb LAM-ICP-MS analysis yielded zircon crystallization ages of 288.1+ or -4.5 Ma, 276.5+ or -5,1 Ma and 264.9+ or -4.0 Ma, related to the magmatic intrusion. Geochemical and modal variations show a compositional spectrum between diorite and granite, whereas LREE enrichment, Ti and Nb anomalies and geochemical discrimination suggest that this granitoid suite was formed within a magmatic arc setting. Inherited zircons suggest that this Early Permian plutonism was formed with the participation of Neoproterozoic and Grenvillian basement proximal to the South American continent. Evidence of a superimposed Early Triassic (ca. 250 Ma) deformational event in Santa Marta, together with a well defined S-type magmatism in the basement rocks from the adjacent lower Magdalena Valley and Guajira Peninsula regions are related to a major shift in the regional tectonic evolution. It's envisioned that this event records either terrane accretion or strong plate coupling during the final stages of Pangea agglutination. Connections with the main Alleghanian-Ouachitan Pangean orogen are precluded due to their timing differences. The plutons temporally and compositionally correlate with an arc found in the northern Andes and Mexican Gondwana terranes, and represent a broader magmatic event formed at the proto-Pacific margin, outside the nucleus of the Laurentia-Gondwana Alleghanian-Oachitan orogens. Evidence of lower temperature recrystallization is probably linked to a younger Late Cretaceous deformational event that reworked the margin during the accretion of the Caribbean arc to the northwest of South America.

On all three planets, fine-grained ejecta form circular haloes that extend beyond the continuous ejecta and other types of distal deposits such as run-out lobes or ramparts. Using Earth-based radar images, we find that lunar fine-grained ejecta haloes represent meters-thick deposits with abrupt margins, and are depleted in rocks > or =1 cm in diameter. Martian haloes show low nighttime thermal IR temperatures and thermal inertia, indicating the presence of fine particles estimated to range from nearly equal 10 mu m to 10 mm. Using the large sample sizes afforded by global datasets for Venus and Mars, and a complete nearside radar map for the Moon, we establish statistically robust scaling relationships between crater radius R and fine-grained ejecta run-out r* for all three planets. On the Moon, r* nearly equal R (super -0.18) for craters 5-640 km in diameter. For Venus, radar-dark haloes are larger than those on the Moon, but scale as r* nearly equal R (super -0.49) , consistent with ejecta entrainment in Venus' dense atmosphere. On Mars, fine-ejecta haloes are larger than lunar haloes for a given crater size, indicating entrainment of ejecta by the atmosphere or vaporized subsurface volatiles, but scale as R (super -0.13) , similar to the ballistic lunar scaling. Ejecta suspension in vortices generated by passage of the ejecta curtain is predicted to result in ejecta run-out that scales with crater size as R (super 1/2) , and the wind speeds so generated may be insufficient to transport particles at the larger end of the calculated range. The observed scaling and morphology of the low-temperature haloes leads us rather to favor winds generated by early-stage vapor plume expansion as the emplacement mechanism for low-temperature halo materials.

Both Hrdlicka [The Aleutian and Commander Islands and Their Inhabitants (Philadelphia: Wistar Institute of Anatomy and Biology, 1945)] and Laughlin [`The Alaska gateway viewed from the Aleutian Islands,' in Papers on the Physical Anthropology of the American Indian, W.S. Laughlin, ed. (New York: Viking Fund, 1951), 98-126] analyzed cranial morphology and came to somewhat different conclusions using a typological approach and limited analytical methods. Subsequent investigations using morphological data have not significantly improved our understanding of Aleut prehistory. More recently, radiocarbon dating and mitochondrial DNA analyses have shed light on Aleut genetic variation and changes over time, but better morphological methods using multivariate statistical analysis have not yet been used. We analyzed craniometric data using multivariate procedures and found that Aleuts demonstrate significant changes in cranial morphology over time, and these changes correspond to Hrdlicka's observations but may not necessarily reflect in-migration. The morphological changes were concentrated in the very aspects of morphology that are easily observable and that Hrdlicka most often measured, namely, cranial length, breadth, and height, but they were obscured when craniometric variation as a whole was analyzed. Also, we found that the morphological changes over time were not related to the changes in haplogroup frequencies over time, suggesting that migration into the Aleutians did not play a significant role in producing the morphological changes. However, craniometric variability apparently increases over time, suggesting in-migration, localized selection, and/or greater environmental heterogeneity. Our results contradict Laughlin's observations but may be more in line with his hypothesis of in situ evolutionary changes absent gene flow. In addition to selection, gene flow, and gene drift, however, sociocultural changes must also be considered as a factor in why morphology changed over time.

However, most of these programs rely on indirect sign surveys of elusive animals that often leave cryptic signs of their presence. In Sichuan Province, China, sign surveys are oriented mainly toward giant panda (Ailuropoda melanoleuca) populations but also are used to track other nationally listed species. We have developed and tested a monitoring system based on camera-trapping that can detect a wide range of large, terrestrial mammal and bird species within the reserves of Sichuan. This system is embedded within current protected area patrolling activities and relies on a partnership of management agencies, universities and international organizations. The international organizations and national universities primarily provide the training and assist with study design and data analysis. Data management and access is controlled at the regional level by the appropriate state agencies. Limitations to this system include the need for additional training and support to less developed reserves and the long-term availability of funds to support field staff. However, the potential return on investment is a consistent tracking of multiple species across diverse set of reserves, facilitating comparative analysis of results that will assist in adaptive management throughout the region.

Seventy-six samples collected in 2004 were analyzed to establish the modern distribution and abundance of foraminifera. Cluster analysis defined four modern biofacies: Marsh (dominated by Trochammina inflata and Haplophragmoides wilberti), Estuarine High Salinity A (dominated by Ammonia parkinsoniana and Elphidium mexicanum), Estuarine High Salinity B (dominated by Ammonia parkinsoniana and Elphidium excavatum), and Estuarine Low Salinity (dominated by Ammotium salsum, Ammonia parkinsoniana and Elphidium gunteri). The four biofacies were also recognized by discriminant analysis. Comparison of the 2004 distributional data with those derived from samples collected in 1959 from central and eastern Core Sound revealed that Elphidium decreased while Ammonia increased in relative abundance. Other researchers have suggested that such a trend reflects increased eutrophication, although there is no independent evidence for this in Core Sound. The temporal comparison also showed that Quinqueloculina has become more widespread immediately adjacent to barrier islands, which might relate to an increase in subaquatic vegetation. Five short cores were taken in mainland bays on the western margin of Core Sound. Analysis of radionuclides ( (super 210) Pb and (super 137) Cs) provided a chronostratigraphic framework for two of the cores. To aid paleoenvironmental interpretations, foraminiferal data from core sediments dated as ca. 90 yr were entered as unknowns into the modern distribution discriminant analysis. Samples from mainland bay cores were classified with modern biofacies and indicated no significant foraminiferal change in the mainland bays over the last ca. 90 years.

It is conceived that a launch vehicle such as that studied for the Ares V will carry a monolithic 16-m-diameter mirror to the earth-sun L2 point. Even with such a vehicle, the reflectors comprising the [[approximate]] 250 nested shells must be extremely light-weight. Therefore their figure and alignment cannot be achieved on the ground, and likely could not be maintained through the launch environment. We will present a conceptual solution to those constraints: adjustable X-ray optics, as a case of "adaptive" optics where the stability once in orbit should require adjustments no more frequently than yearly. The figure would be adjusted via thin-film actuators deposited directly to the back (non-reflecting) side of each element. This bi-morph configuration would impart in-plane strains via the piezoelectric or electrostrictive effect. Requirements of the adjustment are to the order of a few nanometer precision. Each shell, and each module, must also be aligned, to tolerances of about 0.1 micrometer. We conceive that on-orbit data would be acquired by a built-in Hartmann system for the alignment adjustments and low-order figure, and by ring profile measurements of a very bright celestial X-ray source to correct figure errors up to the mid-frequency range of several hundredths cycles mm super(-1).

In 1995, conservation managers translocated eight female pumas (P. c. stanleyana) from Texas to increase depleted genetic diversity, improve population numbers, and reverse indications of inbreeding depression. We have assessed the demographic, population-genetic, and biomedical consequences of this restoration experiment and show that panther numbers increased threefold, genetic heterozygosity doubled, survival and fitness measures improved, and inbreeding correlates declined significantly. Although these results are encouraging, continued habitat loss, persistent inbreeding, infectious agents, and possible habitat saturation pose new dilemmas. This intensive management program illustrates the challenges of maintaining populations of large predators worldwide.

Martian wind streaks are among the most abundant surface features on the planet and commonly extend from the downwind margins of impact craters. Previous studies of wind streaks emerging from crater interior deposits suggested that the mode of emplacement was primarily related to the deposition of silt-sized particles as these settled from plumes. We have performed geologic investigations of two wind streaks clusters; one situated in western Arabia Terra, a region in the northern hemisphere of Mars, and another in an analogous terrestrial site located in southern Patagonia, Argentina, where occurrences of wind streaks emanate from playas within maar craters. In both these regions we have identified bedforms in sedimentary deposits on crater floors, along wind-facing interior crater margins, and along wind streaks. These observations indicate that these deposits contain sand-sized particles and that sediment migration has occurred via saltation from crater interior deposits to wind streaks. In Arabia Terra and in Patagonia wind streaks initiate from crater floors that contain lithic and evaporitic sedimentary deposits, suggesting that the composition of wind streak source materials has played an important role in development. Spatial and topographic analyses suggest that regional clustering of wind streaks in the studied regions directly correlates to the areal density of craters with interior deposits, the degree of proximity of these deposits, and the craters' rim-to-floor depths. In addition, some (but not all) wind streaks within the studied clusters have propagated at comparable yearly (Earth years) rates. Extensive saltation is inferred to have been involved in its propagation based on the studied terrestrial wind streak that shows ripples and dunes on its surface and the Martian counterpart changes orientation toward the downslope direction where it extends into an impact crater.

Changes in fecal deposition patterns associated with reproduction in kit foxes (Vulpes macrotis) might affect results of such surveys. We used a trained dog to collect fresh scats on 2-km transects in the home ranges of 11 radiocollared female kit foxes in January, February, and March 2008 and determined sex of the individual that deposited the scats by amplifying the zinc finger protein gene. Female foxes give birth in mid-February to mid-March. We found a similar number of scats each month. In January, the sex ratio of the scats was not different from the expected 1[ratio]1. However, in February there were almost 2 male scats for every female scat and in March there were >8 male scats for every female scat. Comparing March to January, there were more male scats on all 11 transects and fewer female scats on 10 of 11 transects. Around the time pups are born, both sexes appear to show changes in fecal deposition patterns that make it easier to find male scats and harder to find female scats. Effects of these changes on survey results will vary depending on the purpose and design of the survey. Surveys to determine distribution and relative abundance would probably not be negatively affected by these changes. However, if surveys to estimate abundance are conducted during the reproductive season, they could result in an underestimate of population size unless the increased heterogeneity in scat detectability is taken into account.

AN - 755157299; 2010-081079 AB - Sequence stratigraphic analysis of Pennsylvanian coal-bearing strata suggests that glacial-interglacial fluctuations at high latitudes drove cyclic changes in tropical biomes. A literature review of plant assemblages in this paleoclimatic context suggests that coal forests dominated during humid interglacial phases, but were replaced by seasonally dry vegetation during glacial phases. After each glacial event, coal forests reassembled with largely the same species composition. This remarkable stasis implies that coal-forest refugia existed across the equatorial landscape during glacial phases, expanding to repopulate lowlands during and following deglaciation. One possibility is that refugia comprised small pockets of wetland forest strung out along valleys at some sites, but data are currently insufficient to test this hypothesis. The model presented here, if accepted, dramatically alters our understanding of the coal forests and helps explain aspects of their dynamics.

While early approaches were purely spatial in nature, it is now possible to explore the underlying causes of spatial heterogeneity of biological variation using a wealth of environmental data, especially from satellite remote sensing. Recent methods can not only make inferences regarding spatial relationships and the causes of spatial heterogeneity, but also create predictive maps of patterns of biological variation under changing environmental conditions. Here, we review the methods involved in making continuous spatial predictions from biological variation using spatial and environmental predictor variables, provide examples of their use and critically evaluate the advantages and limitations. In the final section, we discuss some of the key challenges and opportunities for future work.

From these measurements and catalog optical photometry we derive albedos and diameters of the observed targets. The overall goal of our ExploreNEOs program is to study the history of near-Earth space by deriving the physical properties of a large number of NEOs. In this paper, we describe both the scientific and technical construction of our ExploreNEOs program. We present our observational, photometric, and thermal modeling techniques. We present results from the first 101 targets observed in this program. We find that the distribution of albedos in this first sample is quite broad, probably indicating a wide range of compositions within the NEO population. Many objects smaller than 1 km have high albedos (> or =0.35), but few objects larger than 1 km have high albedos. This result is consistent with the idea that these larger objects are collisionally older, and therefore possess surfaces that are more space weathered and therefore darker, or are not subject to other surface rejuvenating events as frequently as smaller NEOs.
