To determine the role of grazing intensity on grassland ecosystem CO2 fluxes, we used static chamber methods to measure net ecosystem exchange for CO2 (NEE) and its two components, gross ecosystem production (GEP) and ecosystem respiration (Re), during three growing seasons on a steppe site located at the southeastern edge of the Mongolian Plateau in China. Objectives were to document how NEE, GEP and Re varied seasonally and interannually, and to examine how environmental factors and grazing intensity influenced the C budget. Sheep grazed during the growing seasons of 2012-14 at a stocking rate of 0,1.43 and 2.33 sheep units ha (-1)year(-1) for ungrazed (UG), moderately grazed (MG) and heavily grazed (HG) sites, respectively. Results showed that both grazing intensity and climatic variability significantly affected NEE, GEP and Re. Precipitation or soil water content and aboveground biomass (AGB) critically controlled NEE and GEP. Precipitation during the growing season of 2013 was 34% greater than that in 2014 and 2012, and 38% higher than long-term mean precipitation (244 mm, 1953-2012). Precipitation was low between days 150-260 in 2012 and 2013 compared to that in 2014 with lower precipitation during days 205-260. Despite strong intra- and interannual influences on ecosystem CO2 fluxes, interaction of year and grazing intensity only affected NEE (P = 0.026) and not GEP (P = 0.286) or Re (P = 0.984). Seasonal values of NEE (-7.5 mu mol CO2 m(-2)s(-1)), GEP (-12.2 mu mol CO2 m(-2)s(-1)), and Re (3.4 mu mol CO2 m(-2)s(-1)) in 2013 were approximately 47% (46-48%), 34% (33-35%), and 22% (6-38%) higher than those in 2012 and 2014, respectively. The temperate steppe in northern China was a sink for C during the growing season for the grazing intensities evaluated in our study with the MG site exhibiting the greatest NEE and GEP. Mean cumulative carbon uptake for MG was 1005 +/- 45 g C m(-2), which was 31 and 98% greater than that for UG and HG, respectively. Results from our study suggested that both no grazing and heavy grazing significantly decreased C fixation of the steppe grassland (P < 0.05) in northern China. In addition, annual precipitation and its associated distribution mediated the magnitude of reduction in C fluxes. (C) 2016 Elsevier B.V. All rights reserved.

TI Reconsidering rest following fire: Northern mixed-grass prairie is resilient to grazing following spring wildfire SO AGRICULTURE ECOSYSTEMS & ENVIRONMENT LA English DT Article DE Grassland; Grazing management; Land management; Post-fire grazing; Rangeland; Wildfire ID TALLGRASS PRAIRIE; CRESTED WHEATGRASS; POSTFIRE SUCCESSION; SAGEBRUSH STEPPE; PLANT COMMUNITY; GREAT-PLAINS; SUMMER FIRE; PRODUCTIVITY; DISTURBANCE; ECOSYSTEMS AB Current federal post-fire land management recommendations in the United States suggest that rangelands be rested from grazing for two growing seasons following fire to allow for proper recovery, despite the lack of empirical literature supporting this recommendation. This project was designed to determine if grazing the first growing season following a spring wildfire alters subsequent productivity and species composition of northern mixed-grass prairie. Following the April 2013 Pautre wildfire in northwestern South Dakota, 100 m(2) exclosures were erected in three burned pastures to simulate two growing seasons of rest. Grazing exclosures were paired with sites grazed both the first and second growing seasons following the fire and replicated across loamy and sandy ecological sites. Prior to grazing the second growing season, five 2 m(2) cages were placed at each grazed site to assess first-year grazing effects. Following the second growing season, productivity and species composition were determined for exclosures and cages. Productivity was greater for loamy than sandy ecological sites (loamy = 2764 kg ha(-1), sandy = 2356 kg ha(-1); P=0.0271), but was similar between grazing treatments (rested = 2556 kg ha(-1), grazed = 2564 kg ha(-1); P=0.9550). Ecological site strongly determined species composition. Loamy sites consistently contained more Pascopyrum smithii, Bouteloua gracilis and Carex duriuscula than sandy sites (30 v 0%, 18 v 8%, 4 v 1%; P=0.0004, 0.0457 and 0.0382 respectively). The effects of grazing exclusion were limited to Hesperostipa comata and the non-native Agropyron cristatum composition. H. comata was more prevalent on rested sites (22 v 15%, P= 0.0096). A. cristatum experienced a grazing treatment by ecological site interaction as it was reduced by grazing on sandy sites, but was not affected on loamy sites (P=0.0226). Results do not support the notion that a two growing season rest period following fire is required in the northern mixed-grass prairie. Published by Elsevier B.V.

TI An Inert Pesticide Adjuvant Synergizes Viral Pathogenicity and Mortality in Honey Bee Larvae SO SCIENTIFIC REPORTS LA English DT Article ID COLONY COLLAPSE DISORDER; APIS-MELLIFERA L.; ORGANOSILICONE SURFACTANT; TRISILOXANE SURFACTANTS; MASS-SPECTROMETRY; VIRUSES; DROSOPHILA; DEFENSE; TRANSMISSION; PREVALENCE AB Honey bees are highly valued for their pollination services in agricultural settings, and recent declines in managed populations have caused concern. Colony losses following a major pollination event in the United States, almond pollination, have been characterized by brood mortality with specific symptoms, followed by eventual colony loss weeks later. In this study, we demonstrate that these symptoms can be produced by chronically exposing brood to both an organosilicone surfactant adjuvant (OSS) commonly used on many agricultural crops including wine grapes, tree nuts and tree fruits and exogenous viral pathogens by simulating a horizontal transmission event. Observed synergistic mortality occurred during the larval-pupal molt. Using q-PCR techniques to measure gene expression and viral levels in larvae taken prior to observed mortality at metamorphosis, we found that exposure to OSS and exogenous virus resulted in significantly heightened Black Queen Cell Virus (BQCV) titers and lower expression of a Toll 7-like-receptor associated with autophagic viral defense (Am18w). These results demonstrate that organosilicone spray adjuvants that are considered biologically inert potentiate viral pathogenicity in honey bee larvae, and guidelines for OSS use may be warranted.

TI Advances and Environmental Conditions of Spring Migration Phenology of American White Pelicans SO SCIENTIFIC REPORTS LA English DT Article ID CLIMATE-CHANGE; PHENOTYPIC PLASTICITY; BIRD MIGRATION; ECOLOGICAL CONDITIONS; ARRIVAL DATE; HABITAT USE; WINTER; EVOLUTIONARY; MOVEMENTS; TELEMETRY AB Spring migration phenology of birds has advanced under warming climate. Migration timing of short-distance migrants is believed to be responsive to environmental changes primarily under exogenous control. However, understanding the ecological causes of the advancement in avian spring migration phenology is still a challenge due to the lack of long-term precise location data. We used 11 years of Global Positioning System relocation data to determine four different migration dates of the annual migration cycle of the American white pelican (Pelecanus erythrorhynchos), a short-distance migrant. We also tested the hypothesis that increases in winter temperature and precipitation on the wintering grounds would advance pelican spring migration. Pelican spring departures and arrivals advanced steadily from 2002 to 2011. Spring departure timing exhibited high repeatability at the upper end of migration timing repeatability reported in literature. However, individual spring departure and arrival dates were not related to winter daily temperature, total winter precipitation, and detrended vegetation green-up dates indexed by the normalized difference vegetation index. Despite high repeatability, the observed between-year variation of spring departure dates was still sufficient for the advancement of spring departure timing. C1 [King, D.

The intensive use of synthetic acaricides for tick control exerts a strong selective pressure for brown dog ticks to become resistant to them. Here, we investigated claims from the field regarding treatment failure associated with the use of veterinary products containing ivermectin (IVM) to control brown dog ticks infesting dogs in Yucatan state, Mexico. Dogs in six state municipalities were inspected to sample 15 R. sanguineus s.l. populations. Interviews were conducted with dog owners to gather information on the history of dog treatment with conventional acaricides and IVM. The larval immersion test was used on the progeny of adult female ticks infesting dogs to test for susceptibility to IVM. Dose-mortality regressions, lethal concentrations (LC), their confidence intervals, and slope were estimated by probit analysis. Ten tick populations (66.7%) were classified as resistant compared with the most susceptible population. A high inter-population variation in the phenotypic level of IVM resistance was evident (resistance ratio at LC50% andLC(99%) ranged from 1.0 to 30.5, and from 1.0 to 458.8, respectively). Tick populations classified as resistant were collected from dogs known to have been treated with IVM. To our knowledge, this is the first report of IVM resistance in R. sanguineus s.l. worldwide. Veterinary and pet owner education on integrated tick management practices is required to avoid widespread resistance and increased treatment failure with products containing IVM and other macrocyclic lactones used to control endo- and ectoparasites affecting dogs. Integrated tick management will also help mitigate the burden of brown dog tick-borne diseases on human and animal populations. (C) 2016 Elsevier B.V. All rights reserved. C1 [Rodriguez-Vivas, R.

Intense agriculture leads to a loss in species richness and homogenization of species pools, but the processes behind are poorly understood due to a lack of systematic case studies: The specific impacts by agriculture in contrast to other land-use creating open habitat are not studied as such landscapes hardly exist in temperate regions. Applying systematic grids, we compared the plant species distribution at the landscape scale between an active military training areas in Europe and an adjacent rather intensively used agricultural landscape. As the study areas differ mainly in the type of disturbance regime (agricultural vs. non-agricultural), differences in species pattern can be traced back more or less directly to the management. Species trait analyses and multiple measures of beta diversity were applied to differentiate between species similarities between plots, distance-decay, or nestedness. Contrary to our expectation, overall beta diversity in the agricultural area was not reduced but increased under agricultural. This was probably the result of species nestedness due to fragmentation. The natural process of increasing dissimilarity with distance (distance-decay) was suppressed by intense agricultural land-use, generalist and long-distance dispersers gained importance, while rare species lost continuity. There are two independent processes that need to be addressed separately to halt biodiversity loss in agricultural land. There is a need to conserve semi-natural open habitat patches of diverse size to favor poor dispersers and specialist species. At the same time, we stress the importance of mediating biotic homogenization caused by the decrease of distance-decay: The spread of long-distance dispersers in agricultural fields may be acceptable, however, optimized fertilizer input and erosion control are needed to stop the homogenization of environmental gradients due to nitrogen input into semi-natural habitat.

The incorporation of 1 and 1.5 wt% CNC by dispersing in the epoxy matrix of short GF/epoxy SMC composites with 25 wt% GF content (25GF/CNC-epoxy) produced 7.5% lighter composites with the same tensile and flexural properties of 35GF/epoxy composites with no CNC. The addition of 1 wt% CNC in 25GF/CNC-epoxy SMC composites resulted in increases of 15% in elastic modulus, 11% in flexural modulus and 14% in flexural strength, reaching the corresponding properties of 35GF/epoxy SMC composites. Moreover, it was found that although addition of CNC did not alter the impact energy, removing 10 wt% GF resulted in reduction of impact energy. (C) 2016 Elsevier Ltd. All rights reserved.

The substantial increase in white-tailed deer (Odocoileus virginianus Zimmerman) populations over the past decades has resulted in heavy browse pressure in many of these forests. To gain an objective assessment of the role of deer in forested ecosystems, a region-wide forest inventory across the northern US was examined in concert with white-tailed deer density information compiled at broad scales. Results indicate that deer density may be an additional driver of tree seedling abundance when analyzed along with stand attributes such as aboveground biomass, relative density, and stand age. Tree seedling abundance generally decreased as deer density increased above 5.8 deer km(2) for all forest type groups with the exception of oak-dominated forests. Findings indicate that introduced plant species, of which 393 were recorded in this study, increased in areas with higher deer density. The abundance of white-tailed deer is just as important as forest stand and site attributes in the development of forest understories. Given the complexity of forest and land use dynamics across the northern US, this study provides directions for future research as more data linking forest-dependent wildlife and forest dynamics at regional and national scales become available.

Despite the proximity of susceptible coast live oak (Quercus agrifolia) forests to densely populated urban areas, the impacts of SOD on their fuels have not been studied. We sampled surface fuels and vegetation structure in 16 plots in both SOD-caused gaps and intact stands (32 plots total) across two parks in the East Bay Regional Park District, east of San Francisco Bay. Plots were selected from a set of randomly placed pre-existing locations used in determining the disease distribution and intensity across the park system. Among the vegetation characteristics examined, only coast live oak basal area and live and dead tree density, canopy cover and maximum forb height differed between SOD created gap plots and adjacent intact forest plots. However, surface fuels such as vegetation cover, litter cover, wood cover, duff depth, fuels height, ladder fuels abundance, 1 h, 10 h, 100 h, and 1000 h fuels were greater in gap plots than intact forest plots. Although no fire behavior models were run, surface fuels suggest SOD created gaps may facilitate passive crown fire due to increased ladder and other fuels. This study represents a spatially explicit (gap focused) point-in-time estimate of surface fuels that will continue to change through time as disease progresses through these stands causing vegetation changes as fuels accumulate and decompose.

Early detection of infestations could allow forest managers to mitigate outbreaks or anticipate a response to tree mortality and the potential effects on ecosystem services of interest. However, the subtle changes in the foliage of infested spruce make early detection difficult. An experiment was conducted in southern Colorado to determine important wavelengths for detecting early-stage (i.e. recently infested) spruce beetle infestation in Engelmann spruce. Spectral reflectance from non-infested and recently infested spruce needles were obtained using the ASDi Field-Spec Pro spectroradiometer. After pre-processing, random forest analysis was used to identify hyperspectral bands and aggregations of hyperspectral bands corresponding to Landsat TM bands and vegetation indices that effectively discriminated between non-infested and infested trees. Results show that the shortwave infrared region of the electromagnetic spectrum was a key area for detecting early stages of spruce beetle infestation, likely due to the effects of beetle infestation on water transport within Engelmann spruce. The strong discriminability of bands in the shortwave infrared region indicates a potential for this spectral region to be used to detect early stage spruce beetle infestation over larger areas using multispectral satellite imagery. In a preliminary trial, we found that a time series of reflectance in Landsat TM band 7 (shortwave infrared) was strongly correlated with the progression through time of a spruce beetle outbreak in southern Wyoming. These findings suggest that multispectral indicators of early-stage spruce beetle outbreak can be developed. These indicators are needed to better understand spatiotemporal dynamics of spruce beetle outbreaks, and can be used by forest managers to detect early stages of spruce beetle infestation and to potentially mitigate some spruce mortality.

Recent studies have shown, however, that the presence of understory vegetation can increase soil carbon and nutrient content, especially where N-fixing species are present. To investigate whether this response can be attributed to changes in soil microbial communities, we conducted experiments with isotopically-labeled litter in Pinus ponderosa stands where N-fixing understory species were present (UP) or absent (UA). We measured carbon and nutrient stocks and monitored changes in soil microbial biomass and composition. Field and laboratory experiments strongly suggest that understory suppression and relatively small changes in litter quality can yield significant changes in soil C and N stocks, which are critical to maintaining forest productivity. We detected a greater accumulation of carbon and nitrogen (relative to controls) when mixtures of pine and N-rich litter were applied to the soil. In contrast, soils amended only with pine litter showed a net loss of carbon and nitrogen stocks. Soil microbial biomass was significantly higher in UP than in UA stands and microbial community composition varied with type of litter inputs and incubation time (0-180 days), but not as a function of understory management. Similar results were obtained from field experiments, in which mesocosms were incubated for similar to 2.5 years with pine and N-rich understory litter mixtures. The suppression of understory species caused a decline in litter-derived carbon and nitrogen in the soil, even when the microbial community was resilient to the imposed treatments.

TI Modeling the capacity of riverscapes to support beaver dams SO GEOMORPHOLOGY LA English DT Article DE North American beaver; Connectivity; Stream restoration; Habitat modeling; Riparian restoration; Fuzzy inference systems ID CASTOR-CANADENSIS; FUZZY-LOGIC; CLASSIFICATION-SYSTEM; HABITAT SUITABILITY; RIPARIAN VEGETATION; RESTORATION EFFORTS; HEADWATER STREAMS; SPECIES RICHNESS; EASTERN OREGON; RIVER-BASIN AB The construction of beaver dams facilitates a suite of hydrologic, hydraulic, geomorphic, and ecological feedbacks that increase stream complexity and channel-floodplain connectivity that benefit aquatic and terrestrial biota. Depending on where beaver build dams within a drainage network, they impact lateral and longitudinal connectivity by introducing roughness elements that fundamentally change the timing, delivery, and storage of water, sediment, nutrients, and organic matter. While the local effects of beaver dams on streams are well understood, broader coverage network models that predict where beaver dams can be built and highlight their impacts on connectivity across diverse drainage networks are lacking. Here we present a capacity model to assess the limits of riverscapes to support dam-building activities by beaver across physiographically diverse landscapes. We estimated dam capacity with freely and nationally-available inputs to evaluate seven lines of evidence: (1) reliable water source, (2) riparian vegetation conducive to foraging and dam building, (3) vegetation within 100 m of edge of stream to support expansion of dam complexes and maintain large colonies, (4) likelihood that channel-spanning dams could be built during low flows, (5) the likelihood that a beaver dam is likely to withstand typical floods, (6) a suitable stream gradient that is neither too low to limit dam density nor too high to preclude the building or persistence of dams, and (7) a suitable river that is not too large to restrict dam building or persistence. Fuzzy inference systems were used to combine these controlling factors in a framework that explicitly also accounts for model uncertainty. The model was run for 40,561 km of streams in Utah, USA, and portions of surrounding states, predicting an overall network capacity of 356,294 dams at an average capacity of 8.8 dams/km. We validated model performance using 2852 observed dams across 1947 km of streams. The model showed excellent agreement with observed dam densities where beaver dams were present. Model performance was spatially coherent and logical, with electivity indices that effectively segregated capacity categories. That is, beaver dams were not found where the model predicted no dams could be supported, beaver avoided segments that were predicted to support rare or occasional densities, and beaver preferentially occupied and built dams in areas predicted to have pervasive dam densities. The resulting spatially explicit reach-scale (250 m long reaches) data identifies where dam-building activity is sustainable, and at what densities dams can occur across a landscape. As such, model outputs can be used to determine where channel-floodplain and wetland connectivity are likely to persist or expand by promoting increases in beaver dam densities.

In this paper we explore how continuity and discontinuity represent fundamental and complementary perspectives in fluvial geomorphology, and how these perspectives inform and underlie our conceptions of connectivity in landscapes and rivers. We examine the historical roots of continuum and discontinuum thinking, and how much of our understanding of geomorphology rests on contrasting views of continuity and discontinuity. By continuum thinking we refer to a conception of geomorphic processes as well as geomorphic features that are expressed along continuous gradients without abrupt changes, transitions, or thresholds. Balance of forces, graded streams, and hydraulic geometry are all examples of this perspective. The continuum view has played a prominent role in diverse disciplinary fields, including ecology, paleontology, and evolutionary biology, in large part because it allows us to treat complex phenomena as orderly progressions and invoke or assume equilibrium processes that introduce order and prediction into our sciences. In contrast the discontinuous view is a distinct though complementary conceptual framework that incorporates non-uniform, non-progressive, and non-equilibrium thinking into understanding geomorphic processes and landscapes. We distinguish and discuss examples of three different ways in which discontinuous thinking can be expressed: 1) discontinuous spatial arrangements or singular events; 2) specific process domains generally associated with thresholds, either intrinsic or extrinsic; and 3) physical dynamics or changes in state, again often threshold-linked. In moving beyond the continuous perspective, a fertile set of ideas comes into focus: thresholds, non-equilibrium states, heterogeneity, catastrophe. The range of phenomena that is thereby opened up to scientific exploration similarly expands: punctuated episodes of cutting and filling, discretization of landscapes into hierarchies of structure and control, the work of extreme events. Orderly and progressive evolution towards a steady or ideal state is replaced by chaotic episodes of disturbance and recovery. Recent developments in the field of geomorphology suggest that we may be on the cusp of a new paradigm that recognizes that both continuous and discontinuous processes and mechanisms play a role in fluvial processes and landscape evolution with neither holding sway over the other and both needed to see rivers as they are.

The Moderate Resolution Imaging Spectroradiometer (MODIS)-derived enhanced vegetation index (EVI) and ground-based climate variables were integrated with eddy covariance tower based ET (ETEc) at six AmeriFlux tallgrass prairie sites in the central United States to determine major climatic factors that control ET over multiple timescales and to develop a simple and robust statistical model for predicting ET. Variability in ET was nearly identical across sites over a range of timescales, and it was most strongly driven by photosynthetically active radiation (PAR) at hourly-to-weekly timescales, by vapor pressure deficit (VPD) at weekly-to-monthly timescales, and by temperature at seasonal-tointerannual timescales at all sites. Thus, the climatic drivers of ET change over multiple timescales. The EVI tracked the seasonal variation of ETEc well at both individual sites (R-2 > 0.70) and across six sites (R-2 = 0.76). The inclusion of PAR further improved the ET-EVI relationship (R-2 = 0.86). Based on this result, we used ETEc, EVI, and PAR (MJ m(-2) d(-1)) data from four sites (15 site-years) to develop a statistical model (ET= 0.11 PAR+ 5.49 EVI 1.43, adj. R-2 = 0.86, P<0.0001) for predicting daily ET at 8-day intervals. This predictive model was evaluated against additional two years of ETEc data from one of the four model development sites and two independent sites. The predicted ET (ETEVI+PAR) captured the seasonal patterns and magnitudes of ETEC, and correlated well with ETEc, with R-2 of 0.87-0.96 and RMSE of 0.35-0.49 mm d(-1), and it was significantly improved compared to the standard MODIS ET product. This study demonstrated that tallgrass prairie ET can be accurately predicted using a multiple regression model that uses EVI and PAR which can be readily derived from remote sensing data.

Future predictions suggest that corn (Zea mays L.) and soybean (Glycine max (L.) Merr.) production in the Midwest may be limited by precipitation and temperature due to climate change. Cross-biome long-term studies in situ are needed to understand carbon assimilation and impact of climate change on the entire region. In this study, we investigated the differences of gross primary production (GPP) and net ecosystem production (NEP) among typical (agro-) ecosystems of corn, soybean and tallgrass prairie from eddy flux stations from 2006 to 2015 under contrasting weather conditions. Corn had the highest annual GPP and NEP with 1305 and 327 g Cm-2 yr(-1), while soybean had significantly lower GPP and NEP with 630 and 34 g Cm-2, excluding additional carbon loss by yield. Corn and soybean NEP was linear related (p < 0.05) to leaf area index (LAI), height or phenological stage, confirming the strong link between plant growth and ecosystem carbon balance. Tallgrass prairie had average values of GPP and NEP of 916 and 61 g Cm-2 yr(-1), excluding loss of carbon by annual burning. Thus, prairie GPP and NEP were significantly lower than corn, but significantly higher than soybean. Probably the long fallow period on cropland, which enhanced heterotrophic respiration, and the low carbon assimilation of soybean reduced its overall carbon balance. In total, the corn-soybean agroecosystem acted as a carbon source due to carbon loss by yield removal. Values for GPP and NEP were reflected in inherent water use efficiency (IWUE*) and light use efficiency (LUE) among the agroecosystems. In addition, IWUE*, LUE or GPP of crops and tallgrass prairie were linearly related (p < 0.05) to precipitation, volumetric soil water content (VWC) and maximum air temperature. Air temperature increased IWUE* in both, cropland and prairie vegetation. However, rainfall and VWC affected crops and prairie vegetation differently: while excessive rainfall and VWC reduced GPP or IWUE* in cropland, prairie vegetation GPP and LUE were adversely affected by reduced VWC or precipitation. Future measures of climate change adaption should consider the contrasting effects of precipitation and VWC among the different agro-ecosystems in the Midwestern USA. (C) 2016 Elsevier B.V.

Parsons, Russell Martin-StPaul, Nicolas TI Representativeness of wind measurements in fire experiments: Lessons learned from large-eddy simulations in a homogeneous forest SO AGRICULTURAL AND FOREST METEOROLOGY LA English DT Article DE Fire metrology; Measurement accuracy; Measurement error; Spatial correlation; Temporal correlation; HIGRAD/FIRETEC ID ATMOSPHERE INTERACTIONS; SPREAD; MODEL; SURFACE; PREDICTIONS; STATISTICS; VALIDATION; FLOW AB Experimental fires often aim to relate fire behavior to fuel and weather conditions, such as wind speeds. These experiments are typically limited to short durations (similar to 300 s) and small lateral extents (similar to 100 m). Although most studies include measurements of wind velocities, such measurements are often taken at some distance from the fire experiments, and may not represent conditions at the fire location. This disparity may potentially introduce errors of unknown magnitude in empirical models based upon the data collected. At present, little guidance is available regarding how well remote anemometry measurements are actually representative of wind velocities at the fire front. A number of factors may affect this representativeness, including the fire itself (size, spread rate and duration), the reference height for fire wind measurement, the sensors (number and location), the vegetation, and weather conditions (wind speed and atmospheric stability). In the present study, we use large-eddy simulations of wind flows to compute fire-front wind (at a virtual moving fire line) and measured wind (at anemometer locations) corresponding to hypothetical fire experiments. Replicates of these hypothetical experiments were used to quantify wind measurement representativeness, by computing the errors resulting from the estimation of the fire-front wind by remote anemometers. We then examine the sensitivity of these errors to the factors mentioned above. We found that the main factors were the size of the experiment, the reference height for wind measurement, the ratio of ambient wind speed to expected spread rate, and the number of sensors. Convective instability and distance between anemometers and fire plots played a minor role in most cases. We propose a simple model to characterize this error as it is influenced by the main factors. The simple model reproduces and generalizes outcomes reported by an earlier field study and shows a clear picture of the respective role of the factors cited above. It can be used to estimate errors in wind measurement in completed experiments. Practical guidelines are provided to apply this model to the design of future experiments.

TI The effective evaluation height for flux-gradient relationships and its application to herbicide fluxes SO AGRICULTURAL AND FOREST METEOROLOGY LA English DT Article DE Agrochemical; Pesticide; Volatilization; Flux-gradient; Metolachlor ID MICROMETEOROLOGICAL TECHNIQUES; METOLACHLOR VOLATILIZATION; PESTICIDE VOLATILIZATION; NITROUS-OXIDE; WATER-QUALITY; SOIL; ATMOSPHERE; SURFACE; LOSSES; SYSTEM AB Volatilization represents a significant loss pathway for many pesticides, herbicides and other agrochemicals. One common method for measuring the volatilization of agrochemicals is the flux-gradient method. Using this method, the chemical flux is estimated as the product of the vertical concentration gradient and a turbulent-transfer coefficient (eddy diffusivity). For computational simplicity, the evaluation height needed to calculate the eddy diffusivity is typically approximated as either the geometric or logarithmic mean. Both of these estimation methods are based on simplifying assumptions and can be a significant source of error, particularly when the separation distance between the measurement heights is large. Using data collected over an eight-year period at the USDA-ARS OPE3 experimental watershed, this study compared fluxes of metolachlor, a commonly-used herbicide, computed using the approximated evaluation heights with those calculated using the exact evaluation height. While it was found that the primary factor influencing the accuracy of the flux estimates using the approximate evaluation heights was atmospheric stability, errors in the estimate of the evaluation height can result in significant (>10%) errors in the flux estimates. Based on these results, it is recommended that the exact evaluation height be used with the flux-gradient technique. Published by Elsevier B.V.

Hence, the objective of this study was to evaluate the influence of topsoil thickness on water infiltration in claypan soils for grain and switchgrass (Panicum virgatum L.) production systems. The experiment was performed at the University of Missouri South Farm (38 degrees 54'N, 92 degrees 16'W) on a Mexico silt loam (Vertic Luvisols) soil. Since 2009, plots were planted,with either switchgrass or a corn (Zea mays L) soybean (Glycine max (L) Merr.) rotation: Infiltration rates were measured using ponded infiltrometers during two years (2014 and 2015) under switchgrass and grain crop management each with two levels of topsoil thickness (0 and 37.5 cm). Physically-based Parlange and Green-Ampt infiltration models were used to estimate saturated hydraulic conductivity (K-s) and sorptivity (S) parameters. Switchgrass planted on degraded soil (shallow topsoil treatment) resulted in greater K-s, S, q(s) (quasi-steady infiltration rate) and K-fs (field-saturated hydraulic conductivity) values than with row crop management for both 2014 and 2015 measurement years. Results for selected 24-hour mean frequency (11.8, 142, and 16.2 cm) storms showed that switchgrass production systems enhanced estimated water infiltration, reduced estimated runoff, and decreased estimated time from water ponding to end of ponding compared with row crop management. Switchgrass is recommended to be planted on degraded soils especially in claypan landscapes for improved water use. (C) 2016 Elsevier B.V. All rights reserved.

We studied the effect of fire on soil cation exchange capacity (CEC) by comparing severely burned soils to nearby unburned soils at five forest and woodland sites in California, USA. Combusted logs and heavy fuel produced reddened zones of thermally altered soil underlain by blackened zones where heat exposure was lower. The cation exchange capacities of the reddened soils were 57 to 82% lower than the unburned soil while the blackened soils had 31 to 53% less CEC than unburned soil. The reddened soil experienced the highest burning temperatures resulting in the loss of organic carbon (OC), the conversion of goethite to maghemite or hematite, the destruction of kaolin, and dehydroxylation and permanent collapse of vermiculite and chlorite. Overall, most of the CEC loss was due to thermal destruction of soil organic matter (SOM), but this CEC will be restored in the post-fire ecosystem succession as biomass re-accumulates and rebuilds soil humus. The loss of CEC due to mineral alteration is longer lasting, though limited in spatial extent. (C) 2016 Elsevier B.V. All rights reserved.

Simultaneously, a wide range of analytical technologies has evolved that allow greater capability for the determination of food composition. Nuclear magnetic resonance (NMR), traditionally a research tool used for structural elucidation, is now being used frequently for metabolomics and chemical fingerprinting. Its stability and inherent ease of quantification have been exploited extensively to identify and quantify bioactive components in foods and dietary supplements. In addition, NMR fingerprints have been used to differentiate cultivars, evaluate sensory properties of food and investigate the influence of growing conditions on food crops. Here we review the latest applications of NMR in food analysis. Published 2016. This article is a U.S. Government work and is in the public domain in the USA.

The need to understand how the germplasm variation in major crops can be utilized to aid in discovering and developing breeding lines that can withstand and adapt to temperature fluctuations is more necessary than ever. Here, we analyzed the genetic variation associated with responses to thermal stresses in a sorghum association panel (SAP) representing major races and working groups to identify single nucleotide polymorphisms (SNPs) that are associated with resilience to temperature stress in a major cereal crop. Results: The SAP exhibited extensive variation for seedling traits under cold and heat stress. Genome-wide analyses identified 30 SNPs that were strongly associated with traits measured at seedling stage under cold stress and tagged genes that act as regulators of anthocyanin expression and soluble carbohydrate metabolism. Meanwhile, 12 SNPs were significantly associated with seedling traits under heat stress and these SNPs tagged genes that function in sugar metabolism, and ion transport pathways. Evaluation of co-expression networks for genes near the significantly associated SNPs indicated complex gene interactions for cold and heat stresses in sorghum. We focused and validated the expression of four genes in the network of Sb06g025040, a basic-helix-loop-helix (bHLH) transcription factor that was proposed to be involved in purple color pigmentation of leaf, and observed that genes in this network were upregulated during cold stress in a moderately tolerant line as compared to the more sensitive line. Conclusion: This study facilitated the tagging of genome regions associated with variation in seedling traits of sorghum under cold and heat stress. These findings show the potential of genotype information for development of temperature resilient sorghum cultivars and further characterization of genes and their networks responsible for adaptation to thermal stresses. Knowledge on the gene networks from this research can be extended to the other cereal crops to better understand the genetic basis of resilience to temperature fluctuations during plant developmental stages.

However, the factors regulating plant-soil feedback, which varies from positive to negative among plant species, remain uncertain. In a large-scale study involving 55 species and 550 populations of North American trees, the type of mycorrhizal association explained much of the variation in plant-soil feedbacks. In soil collected beneath conspecifics, arbuscular mycorrhizal trees experienced negative feedback, whereas ectomycorrhizal trees displayed positive feedback. Additionally, arbuscular mycorrhizal trees exhibited strong conspecific inhibition at multiple spatial scales, whereas ectomycorrhizal trees exhibited conspecific facilitation locally and less severe conspecific inhibition regionally. These results suggest that mycorrhizal type, through effects on plant-soil feedbacks, could be an important contributor to population regulation and community structure in temperate forests.

In northern Wisconsin, as part of the state-wide beaver management program, the Chequamegon-Nicolet National Forest removes beavers from targeted trout streams on U.S. Forest Service lands. However, the success of this management program has not been evaluated. Targeted removals comprise only 3% of the annual beaver harvest, a level of effort that may not affect the beaver population. We used colony location data along Forest streams from 1987-2013 (Nicolet, northeast Wisconsin) and 1997-2013 (Chequamegon, northwest Wisconsin) to assess trends in beaver colony density on targeted trout streams compared to non-targeted streams. On the Chequamegon, colony density on non-targeted trout and non-trout streams did not change over time, while colony density on targeted trout streams declined and then stabilized. On the Nicolet, beaver colony density decreased on both non targeted streams and targeted trout streams. However, colony density on targeted trout streams declined faster. The impact of targeted trapping was similar across the two sides of the Forest (60% reduction relative to non-targeted trout streams). Exploratory analyses of weather influences found that very dry conditions and severe winters were associated with transient reductions in beaver colony density on non-targeted streams on both sides of the Forest. Our findings may help land management agencies weigh more finely calibrated beaver control measures against continued large-scale removal programs.

Such a capacity, however, cannot be achieved without an efficient genotyping platform such as SNP arrays. In this work, we developed a high-density SNP array with 690,662 unique SNPs (herein 690 K array) that were relatively evenly distributed across the entire genome, and covered 98.6% of the reference genome sequence. Here we also report linkage mapping using the 690 K array, which allowed mapping of over 250,000 SNPs on the linkage map, the highest marker density among all the constructed linkage maps. These markers were mapped to 29 linkage groups (LGs) with 30,591 unique marker positions. This linkage map anchored 1,602 scaffolds of the reference genome sequence to LGs, accounting for over 97% of the total genome assembly. A total of 1,007 previously unmapped scaffolds were placed to LGs, allowing validation and in few instances correction of the reference genome sequence assembly. This linkage map should serve as a valuable resource for various genetic and genomic analyses, especially for GWAS and QTL mapping for genes associated with economically important traits.

Neoantigens introduced by bioengineering of a protein drug are a particular cause for concern. The development of a bioengineered recombinant factor VIIa (rFVIIa) analog was discontinued after phase 3 trials because of the development of ADAs. The unmodified parent molecule (rFVIIa), on the other hand, has been successfully used as a drug for more than two decades with no reports of immunogenicity in congenital hemophilia patients with inhibitors. We used computational and experimental methods to demonstrate that the observed ADAs could have been elicited by neoepitopes in the engineered protein. The human leukocyte antigen type of the patients who developed ADAs is consistent with this hypothesis of aneoepitope-driven immune response, a finding that might have implications for the preclinical screening of therapeutic protein analogs.

Compounding these problems, insect pests often vector pathogenic or toxigenic microbes to plants. Previous work has considered plant-insect and plant-microbe interactions separately. Although insects are well-understood to use plant volatiles to locate hosts, microorganisms can produce distinct and abundant volatile compounds that in some cases strongly attract insects. In this paper, we focus on the microbial contribution to plant volatile blends, highlighting the compounds emitted and the potential for variation in microbial emission. We suggest that these aspects of microbial volatile emission may make these compounds ideal for use in agricultural applications, as they may be more specific or enhance methods currently used in insect control or monitoring. Our survey of microbial volatiles in insect-plant interactions suggests that these emissions not only signal host suitability but may indicate a distinctive time frame for optimal conditions for both insect and microbe. Exploitation of these host-specific microbe semiochemicals may provide important microbe- and host-based attractants and a basis for future plant-insect-microbe chemical ecology investigations.

This work studied how the sorption, persistence, and leaching of the two enantiomers of the phytohormone abscisic acid (ABA) in agricultural soil was affected by the amendments of two organoclays (SA-HDTMA and Cloi10) and a biochar derived from apple wood (BC). In conventional 24-h batch sorption experiments, higher affinity toward ABA enantiomers was displayed by SA-HDTMA followed by Cloi10 and then BC. Desorption could be ascertained only in BC, where ABA enantiomers presented difficulties to be desorbed. Dissipation of ABA in the soil was enantioselective with S-ABA being degraded more quickly than R-ABA, and followed the order unamended > Cloi10-amended > BC-amended > SA-HDTMA-amended soil for both enantiomers. Sorption determined during the incubation experiment indicated some loss of sorption capacity with time in organoclay-amended soil and increasing sorption in BC-amended soil, suggesting surface sorption mechanisms for organoclays and slow (potentially pore filling) kinetics in BC-amended soil. The leaching of ABA enantiomers was delayed after amendment of soil to an extent that depended on the amendment sorption capacity, and it was almost completely suppressed by addition of BC due to its irreversible sorption. Organoclays and BC affected differently the final behavior and enantioselectivity of ABA in soil as a consequence of dissimilar sorption capacities and alterations in sorption with time, which will affect the plant and microbial availability of endogenous and exogenous ABA in the rhizosphere.

A surface measurement technique, quartz crystal microbalance with dissipation (QCM-D), was extended for the investigation of real-time binding and hydrolysis of model cellulose surfaces from free fungal cellulases to the cellulosomes of Clostridium thermocellum (Ruminiclostridium thermocellum). In differentiating the activities of cell-free and cell-bound cellulosomes, greater than 68% of the cellulosomes in the crude cell broth were found to exist unattached to the cell across multiple growth stages. The initial hydrolysis rate of crude cell broth measured by QCM was greater than that of cell-free cellulosomes, but the corresponding frequency drop (a direct measure of the mass of enzyme adsorbed to the film) of crude cell broth was less than that of the cell free cellulosomes, consistent with the underestimation of the cell mass adsorbed using QCM. Inhibition of hydrolysis by cellobiose (0-10 g/L), which is similar for crude cell broth and cell-free cellulosomes, demonstrates the sensitivity of the QCM to environmental perturbations of multienzymatic complexes. QCM measurements using multienzymatic complexes may be used to screen and optimize hydrolysis conditions and to develop mechanistic, surface-based models of enzymatic cellulose deconstruction.

Dissipation of excess excitation energy, mediated by photoprotective isoprenoids, is an important defense mechanism against drought and high light when photosynthesis is hampered. We used 50-year-old Douglas-fir trees of four provenances at two common garden experiments to characterize provenance-specific variation in photosynthesis and photoprotective mechanisms mediated by essential and non-essential isoprenoids in response to soil water availability and solar radiation. All provenances revealed uniform photoprotective responses to high solar radiation, including increased de-epoxidation of photoprotective xanthophyll cycle pigments and enhanced emission of volatile monoterpenes. In contrast, we observed differences between provenances in response to drought, where provenances sustaining higher CO2 assimilation rates also revealed increased water-use efficiency, carotenoid-chlorophyll ratios, pools of xanthophyll cycle pigments, beta-carotene and stored monoterpenes. Our results demonstrate that local adaptation to contrasting habitats affected chlorophyll-carotenoid ratios, pool sizes of photoprotective xanthophylls, beta-carotene, and stored volatile isoprenoids. We conclude that intraspecific variation in isoprenoid-mediated photoprotective mechanisms contributes to the adaptive potential of Douglas-fir provenances to climate change.

In particular, the domestic pig is a proven model of human physiology and an agriculturally important species. In this study, we utilized the CRISPR/Cas9 system to edit the NANOS2 gene in pig embryos to generate offspring with mono-allelic and bi-allelic mutations. We found that NANOS2 knockout pigs phenocopy knockout mice with male specific germline ablation but other aspects of testicular development are normal. Moreover, male pigs with one intact NANOS2 allele and female knockout pigs are fertile. From an agriculture perspective, NANOS2 knockout male pigs are expected to serve as an ideal surrogate for transplantation of donor spermatogonial stem cells to expand the availability of gametes from genetically desirable sires.

TI Prevalence of feral swine disturbance at important archaeological sites over a large landscape in Florida SO SCIENTIFIC REPORTS LA English DT Article AB Feral swine are globally known as one of the most destructive invasive vertebrates, damaging native habitats, native plants and animals, agriculture, infrastructure, spreading diseases. There has been little quantification on their disturbance to archaeological sites across a broad landscape. Over 6 years we inspected 293 significant archaeological sites for swine disturbance across a vast area. We found a 42% prevalence of swine disturbance among all sites, with prevalence not distinguishable among prehistoric sites, historic sites, and sites with both components. The areas of disturbance mapped within three historic homestead sites showed 5-26% of total site surface area rooted. Disturbance was not evident upon re-inspection of one of these sites after 18 months, indicating how evidence of disturbance can be obscured in this environment. Thus, our observed 42% prevalence of disturbance should be considered a minimum for disturbance occurring through time. Artifacts depths were < 10 cm of the surface at 85% of the sites and < 20 cm of the surface for 90% of the sites. Feral swine rooting commonly exceeds 20 cm in depth, especially in soft sandy substrates typical of Florida, making the great majority of the studied sites highly vulnerable to artifact damage or displacement.

This significantly hampers ordering of markers, contigs of physical maps and sequence scaffolds and impedes obtaining of high-quality reference genome sequence. Here we report on the construction of high-density and high-resolution radiation hybrid (RH) map of chromosome 4A supported by high-density chromosome deletion map. A total of 119 endosperm-based RH lines of two RH panels and 15 chromosome deletion bin lines were genotyped with 90K iSelect single nucleotide polymorphism (SNP) array. A total of 2316 and 2695 markers were successfully mapped to the 4A RH and deletion maps, respectively. The chromosome deletion map was ordered in 19 bins and allowed precise identification of centromeric region and verification of the RH panel reliability. The 4A-specific RH map comprises 1080 mapping bins and spans 6550.9 cR with a resolution of 0.13 Mb/cR. Significantly higher mapping resolution in the centromeric region was observed as compared to recombination maps. Relatively even distribution of deletion frequency along the chromosome in the RH panel was observed and putative functional centromere was delimited within a region characterized by two SNP markers.

SO BMC GENOMICS LA English DT Article DE Peanut; QTL; Pod length; Pod width; Hundred-pod weight; Yield ID MICROSATELLITE MARKERS; LINKAGE MAP; IDENTIFICATION; REPEAT; GENOME AB Background: Cultivated peanut (Arachis hypogaea L.), an important source of edible oil and protein, is widely grown in tropical and subtropical areas of the world. Genetic improvement of yield-related traits is essential for improving yield potential of new peanut varieties. Genomics-assisted breeding (GAB) can accelerate the process of genetic improvement but requires linked markers for the traits of interest. In this context, we developed a recombinant inbred line (RIL) mapping population (Yuanza 9102 x Xuzhou 68-4) with 195 individuals and used to map quantitative trait loci (QTLs) associated with three important pod features, namely pod length, pod width and hundred-pod weight. Results: QTL analysis using the phenotyping data generated across four environments in two locations and genotyping data on 743 mapped loci identified 15 QTLs for pod length, 11 QTLs for pod width and 16 QTLs for hundred-pod weight. The phenotypic variation explained (PVE) ranged from 3.68 to 27.84%. Thirteen QTLs were consistently detected in at least two environments and three QTLs (qPLA05.7, qPLA09.3 and qHPWA05.6) were detected in all four environments indicating their consistent and stable expression. Three major QTLs, detected in at least three environments, were found to be co-localized to a 3.7 cM interval on chromosome A05, and they were qPLA05.7 for pod length (16.89-27.84% PVE), qPWA05.5 for pod width (13.73-14.12% PVE), and qHPWA05.6 for hundred-pod weight (13.75-26.82% PVE). This 3.7 cM linkage interval corresponds to similar to 2.47 Mb genomic region of the pseudomolecule A05 of A. duranensis, including 114 annotated genes related to catalytic activity and metabolic process. Conclusions: This study identified three major consistent and stable QTLs for pod size and weight which were co-localized in a 3.7 cM interval on chromosome A05. These QTL regions not only offer further investigation for gene discovery and development of functional markers but also provide opportunity for deployment of these QTLs in GAB for improving yield in peanut.

TI A Noninvasive Tool to Assess the Distribution of Pacific Lamprey (Entosphenus tridentatus) in the Columbia River Basin SO PLOS ONE LA English DT Article AB The Pacific lamprey (Entosphenus tridentatus) is an anadromous fish once abundant throughout coastal basins of western North America that has suffered dramatic declines in the last century due primarily to human activities. Here, we describe the development of an environmental DNA (eDNA) assay to detect Pacific lamprey in the Columbia River basin. The eDNA assay successfully amplified tissue derived DNA of Pacific lamprey collected from 12 locations throughout the Columbia River basin. The assay amplifies DNA from other Entosphenus species found outside of the Columbia River basin, but is species-specific within this basin. As a result, the assay presented here may be useful for detecting Entosphenus spp. in geographic range beyond the Columbia River Basin. The assay did not amplify tissue or synthetically derived DNA of 14 commonly sympatric non-target species, including lampreys of the genus Lampetra, which are morphologically similar to Pacific lamprey in the freshwater larval stage.

However, quantitative information is scarce on protein expression profiles under Al stress in crops. In this study, we report on the identification of potential Al responsive proteins from root tips of Al sensitive BR007 and Al tolerant SC566 sorghum lines using a strategy employing iTRAQ and 2D-liquid chromatography (LC) coupled to MS/MS (2D-LC-MS/MS). A total of 771 and 329 unique proteins with abundance changes of >1.5 or <0.67-told were identified in BR007 and SC566, respectively. Protein interaction and pathway analyses indicated that proteins involved in the antioxidant system were more abundant in the tolerant line than in the sensitive one after Al treatment, while opposite trends were observed for proteins involved in lignin biosynthesis. Higher levels of ROS accumulation in root tips of the sensitive line due to decreased activity of antioxidant enzymes could lead to higher lignin production and hyper-accumulation of toxic Al in cell walls. These results indicated that activities of peroxidases and the balance between production and consumption of ROS could be important for Al tolerance and lignin biosynthesis in sorghum.

The land management literature is scarce in the spatially integrated analysis of biophysical and socio-economic data. Localized land management decisions are likely driven by spatially-explicit but often unobserved resource conditions, influenced by an individual's own characteristics, proximal lands and fellow owners. This study examined stated choices over the management of family-owned forests as an example of a resource that captures strong pecuniary and non-pecuniary values with identifiable decision makers. An autoregressive model controlled for spatially autocorrelated willingness-to-harvest (WTH) responses using a sample of residential and absentee family forest owners from the U.S. State of Missouri. WTH responses were largely explained by affective, cognitive and experience variables including timber production objectives and past harvest experience. Demographic variables, including income and age, were associated with WTH and helped define socially-proximal groups. The group of closest identity was comprised of resident males over 55 years of age with annual income of at least $50,000. Spatially-explicit models showed that indirect impacts, capturing spillover associations, on average accounted for 14% of total marginal impacts among statistically significant explanatory variables. We argue that not all proximal family forest owners are equal and owners-in-absentia have discernible differences in WTH preferences with important implications for public policy and future research.

To obtain comprehensive proteomic data from seeds, total protein from a two-rowed (Conrad) and a six-rowed (Lacey) barley cultivar were precipitated in acetone, digested in-solution, and the resulting peptides were analyzed by nano-liquid chromatography coupled with tandem mass spectrometry. Results: The raw mass spectra data searched against Uniprot's Barley database using in-house Mascot search engine identified 1168 unique proteins. Gene Ontology (GO) analysis indicated that the majority of the seed proteins were cytosolic, with catalytic activity and associated with carbohydrate metabolism. Spectral counting analysis showed that there are 20 differentially abundant seed proteins between the two-rowed Conrad and six-rowed Lacey cultivars. Conclusion: This study paves the way for the use of a top-down gel-free proteomics strategy in barley for investigating more complex traits such as malting quality. Differential abundance of hordoindoline proteins impact the seed hardness trait of barley cultivars.

(walnuts and butternuts) is an economically and ecologically important genus in the family Juglandaceae. All Juglans are important nut and timber trees. Juglans regia (Common walnut), J. sigillata (Iron walnut), J. cathayensis (Chinese walnut), J. hopeiensis (Ma walnut), and J. mandshurica (Manchurian walnut) are native to or naturalized in China. A strongly supported phylogeny of these five species is not available due to a lack of informative molecular markers. We compared complete chloroplast genomes and determined the phylogenetic relationships among the five Chinese Juglans using IIumina sequencing. The plastid genomes ranged from 159,714 to 160,367 bp encoding 128 functional genes, including 88 protein-coding genes and 40 tRNA genes each. A complete map of the variability across the genomes of the five Juglans species was produced that included single nucleotide variants, indels (insertions and deletions), and large structural variants, as well as differences in simple sequence repeats (SSR) and repeat sequences. Molecular phylogeny strongly supported division of the five walnut species into two previously recognized sections (Juglans/Dioscaryon and Cardiocaryon) with a 100% bootstrap (BS) value using the complete cp genomes, protein coding sequences (CDS), and the introns and spacers (IGS) data. The availability of these genomes will provide genetic information for identifying species and hybrids, taxonomy, phylogeny, and evolution in Juglans, and also provide insight into utilization of Juglans plants.

Methods: Four combinations of LA and O were incorporated into the ATSB and evaluated in an olfactometer to determine if these combinations could enhance attraction of Aedes aegypti (L.) to the bait. Ae. albopictus (Skuse) and Ae. aegypti were used to determine bait consumption through excrement droplet counts and percent mortality, of the most attractive D-ATSB (1% LA and 1% O) from the olfactory study. Semi-field evaluations were conducted in screened portable field cages to determine if the D-ATSB applied to non-flowering plants controlled more mosquitoes than the fruit-based ATSB, and ASB. Mosquitoes were exposed to D-ATSB and the two controls for 48 h and collected with BGS traps. The catch rates of the BGS traps were compared to determine efficacy of the D-ATSB. Results: During olfactometer evaluations of D-ATSB, Ae. aegypti mosquitoes were more attracted to 1% LA and 1% O compared to the fruit-based toxic sugar bait alone. Both species of mosquito consumed more fruit-based non-toxic bait (ASB) and ATSB than the D-ATSB. For both species, percent mortality bioassays indicated D-ATSB controlled mosquitoes, as compared to non-toxic control, but not more than the fruit based ATSB. Semi-field evaluations, BioGents sentinel traps at 48 h confirmed that ATSB (positive control) controlled Ae. albopictus, but there was no statistical difference between ASB (negative control) and the D-ATSB. No differences were observed between the mosquitoes caught in any of the experimental formulations for Ae. aegypti. Conclusions: L-lactic (1%) and 1-octen-3-ol (1%) added to a fruit-based sugar bait increased attraction of Ae. aegypti and may have future implications in mosquito trapping devices. The addition of the host kairomones did not enhance the consumption and efficacy of the ATSB in laboratory or semi-field evaluations for both mosquito species. We attribute to the absence of other host cues leading to lack of alighting onto bait surfaces to imbibe the toxic bait, as well as a possible decrease in palatability of the bait caused by the addition of the host kairomones.

Cammalleri, Carmelo TI Effect of the revisit interval and temporal upscaling methods on the accuracy of remotely sensed evapotranspiration estimates SO HYDROLOGY AND EARTH SYSTEM SCIENCES LA English DT Article ID WATER-USE EFFICIENCY; EVAPORATIVE FRACTION; ENERGY-BALANCE; SURFACE-TEMPERATURE; MODEL PERFORMANCE; SELF-PRESERVATION; NET-RADIATION; HEAT-FLUX; VARIABILITY; DAYTIME AB Accurate spatially distributed estimates of actual evapotranspiration (ET) derived from remotely sensed data are critical to a broad range of practical and operational applications. However, due to lengthy return intervals and cloud cover, data acquisition is not continuous over time, particularly for satellite sensors operating at medium (similar to 100 m) or finer resolutions. To fill the data gaps between clear-sky data acquisitions, interpolation methods that take advantage of the relationship between ET and other environmental properties that can be continuously monitored are often used. This study sought to evaluate the accuracy of this approach, which is commonly referred to as temporal upscaling, as a function of satellite revisit interval. Using data collected at 20 Ameri-flux sites distributed throughout the contiguous United States and representing four distinct land cover types (cropland, grassland, forest, and open-canopy) as a proxy for perfect retrievals on satellite overpass dates, this study assesses daily ET estimates derived using five different reference quantities (incident solar radiation, net radiation, available energy, reference ET, and equilibrium latent heat flux) and three different interpolation methods (linear, cubic spline, and Hermite spline). Not only did the analyses find that the temporal auto-correlation, i.e., persistence, of all of the reference quantities was short, it also found that those land cover types with the greatest ET exhibited the least persistence. This carries over to the error associated with both the various scaled quantities and flux estimates. In terms of both the root mean square error (RMSE) and mean absolute error (MAE), the errors increased rapidly with increasing return interval following a logarithmic relationship. Again, those land cover types with the greatest ET showed the largest errors. Moreover, using a threshold of 20% relative error, this study indicates that a return interval of no more than 5 days is necessary for accurate daily ET estimates. It also found that the spline interpolation methods performed erratically for long return intervals and should be avoided.

Aside from known cell type-specific receptors and steroidogenic enzymes, little is known about the differences in the gene expression profiles of these four cell types. Analysis of the RNA present in each bovine cell type using Affymetrix microarrays yielded new cell specific genetic markers, functional insight into the behavior of each cell type via Gene Ontology Annotations and Ingenuity Pathway Analysis, and evidence of small and large luteal cell lineages using Principle Component Analysis. Enriched expression of select genes for each cell type was validated by qPCR. This expression analysis offers insight into cell-specific behaviors and the differentiation process that transforms somatic follicular cells into luteal cells. (C) 2016 Elsevier Ireland Ltd.

MOENCH; SEED MATURATION; MUTANT-GENE; STARCH CONCENTRATION; GRAIN QUALITY; WAXY LOCUS; MAIZE; PROTEIN AB Background: Sorghum [Sorghum bicolor (L.) Moench] is an important cereal crop for dryland areas in the United States and for small-holder farmers in Africa. Natural variation of sorghum grain composition (protein, fat, and starch) between accessions can be used for crop improvement, but the genetic controls are still unresolved. The goals of this study were to quantify natural variation of sorghum grain composition and to identify singlenucleotide polymorphisms (SNPs) associated with variation in grain composition concentrations. Results: In this study, we quantified protein, fat, and starch in a global sorghum diversity panel using near-infrared spectroscopy (NIRS). Protein content ranged from 8.1 to 18.8%, fat content ranged from 1.0 to 4.3%, and starch content ranged from 61.7 to 71.1%. Durra and bicolor-durra sorghum from Ethiopia and India had the highest protein and fat and the lowest starch content, while kafir sorghum from USA, India, and South Africa had the lowest protein and the highest starch content. Genome-wide association studies (GWAS) identified quantitative trait loci (QTL) for sorghum protein, fat, and starch. Previously published RNAseq data was used to identify candidate genes within a GWAS QTL region. A putative alpha-amylase 3 gene, which has previously been shown to be associated with grain composition traits, was identified as a strong candidate for protein and fat variation. Conclusions: We identified promising sources of genetic material for manipulation of grain composition traits, and several loci and candidate genes that may control sorghum grain composition. This survey of grain composition in sorghum germplasm and identification of protein, fat, and starch QTL contributes to our understanding of the genetic basis of natural variation in sorghum grain nutritional traits.

Three chloroplast SSRs (mtrnSf-tmGr, mtmL2-trnF, and mtrnL5-trnL3) and the internal transcribed spacer were used to examine the population structure of Helianthemum in northwestern China. A total of 15 populations of the genus were collected. Nine chloroplast haplotypes and two nuclear genotypes were detected. Both the nuclear and chloroplast data showed two lineages in Helianthemum songancum, respectively, distributed in Yili Valley and western Ordos Plateau. A total of 66.81% (p < 0.001) of the genetic variation was supported by this lineage split. A Mantel test showed a significant correlation between genetic distance and geographical distance (r = 0.937, p < 0.001). Based on genetic analyses, cpSSRs data support strong genetic divergence between regions. We speculate that the climate change during the late Tertiary and early Quaternary isolated H. songaricum into their current distribution, resulting in interruption of gene flow, leading to isolation and genetic divergence between the two regions. Meanwhile, possible selfing would increase genetic drift in small fragmented populations, that might account for the observed genetic divergence in both regions. Given the loss of genetic diversity and genetic divergence in small populations of Helianthemum in northwestern China immediate conservation management steps should be taken on the species.

TI Genetic analysis of teat number in pigs reveals some developmental pathways independent of vertebra number and several loci which only affect a specific side SO GENETICS SELECTION EVOLUTION LA English DT Article ID QUANTITATIVE TRAIT LOCI; GENOME-WIDE ASSOCIATION; REPRODUCTIVE TRAITS; RESOURCE POPULATION; LITTER SIZE; MAMMARY-GLAND; QTL; IDENTIFICATION; POLARITY; SWINE AB Background: Number of functional teats is an important trait in commercial swine production. As litter size increases, the number of teats must also increase to supply nutrition to all piglets. Therefore, a genome-wide association analysis was conducted to identify genomic regions that affect this trait in a commercial swine population. Genotypic data from the Illumina Porcine SNP60v1 BeadChip were available for 2951 animals with total teat number (TTN) records. A subset of these animals (n = 1828) had number of teats on each side recorded. From this information, the following traits were derived: number of teats on the left (LTN) and right side (RTN), maximum number of teats on a side (MAX), difference between LTN and RTN (L - R) and absolute value of L - R (DIF). Bayes C option of GENSEL (version 4.61) and 1-Mb windows were implemented. Identified regions that explained more than 1.5% of the genomic variation were tested in a larger group of animals (n = 5453) to estimate additive genetic effects. Results: Marker heritabilities were highest for TTN (0.233), intermediate for individual side counts (0.088 to 0.115) and virtually nil for difference traits (0.002 for L - R and 0.006 for DIF). Each copy of the VRTN mutant allele increased teat count by 0.35 (TTN), 0.16 (LTN and RTN) and 0.19 (MAX). 15, 18, 13 and 18 one-Mb windows were detected that explained more than 1.0% of the genomic variation for TTN, LTN, RTN, and MAX, respectively. These regions cumulatively accounted for over 50% of the genomic variation of LTN, RTN and MAX, but only 30% of that of TTN. Sus scrofa chromosome SSC10:52 Mb was associated with all four count traits, while SSC10:60 and SSC14:54 Mb were associated with three count traits. Thirty-three SNPs accounted for nearly 39% of the additive genetic variation in the validation dataset. No effect of piglet sex or percentage of males in litter was detected, but birth weight was positively correlated with TTN. Conclusions: Teat number is a heritable trait and use of genetic markers would expedite selection progress. Exploiting genetic variation associated with teat counts on each side would enhance selection focused on total teat counts. These results confirm QTL on SSC4, seven and ten and identify a novel QTL on SSC14. C1 [Rohrer, Gary A.; Nonneman, Dan J.] ARS, US Meat Anim Res Ctr, USDA, Clay Ctr, NE 68933 USA.

PIECE serves as a resource for biologists interested in comparing intron-exon organization and provides valuable in-sights into the evolution of gene structure in plant genomes. Recently, we updated PIECE to a new version, PIECE 2.0 (http://probes.pw.usda.gov/piece or http://aegilops.wheat.ucdavis.edu/piece). PIECE 2.0 contains annotated genes from 49 sequenced plant species as compared to 25 species in the previous version. In the current version, we also added several new features: (i) a new viewer was developed to show phylogenetic trees displayed along with the structure of individual genes; (ii) genes in the phylogenetic tree can now be also grouped according to KOG (The annotation of Eukaryotic Orthologous Groups) and KO (KEGG Orthology) in addition to Pfam domains; (iii) information on intronless genes are now included in the database; (iv) a statistical summary of global gene structure information for each species and its comparison with other species was added; and (v) an improved GSDraw tool was implemented in the web server to enhance the analysis and display of gene structure. The updated PIECE 2.0 database will be a valuable resource for the plant research community for the study of gene structure and evolution.

The effects of replacing annual arable crops with perennial bioenergy feedstocks on net GHG production and soil carbon (C) stock are critical to the system-level balance. Here, we compared GHG flux, crop yield, root biomass, and soil C stock under two potential tropical, perennial grass biofuel feedstocks: conventional sugarcane and ratoon-harvested, zero-tillage napiergrass. Evaluations were conducted at two irrigation levels, 100% of plantation application and at a 50% deficit. Peaks and troughs of GHG emission followed agronomic events such as ratoon harvest of napiergrass and fertilization. Yet, net GHG flux was dominated by carbon dioxide (CO2), as methane was oxidized and nitrous oxide (N2O) emission was very low even following fertilization. High N2O fluxes that frequently negate other greenhouse gas benefits that come from replacing fossil fuels with agronomic forms of bioenergy were mitigated by efficient water and fertilizer management, including direct injection of fertilizer into buried irrigation lines. From soil intensively cultivated for a century in sugarcane, soil C stock and root biomass increased rapidly following cultivation in grasses selected for robust root systems and drought tolerance. The net soil C increase over the two-year crop cycle was three-fold greater than the annualized soil surface CO2 flux. Deficit irrigation reduced yield, but increased soil C accumulation as proportionately more photosynthetic resources were allocated belowground. In the first two years of cultivation napiergrass did not increase net greenhouse warming potential (GWP) compared to sugarcane, and has the advantage of multiple ratoon harvests per year and less negative effects of deficit irrigation to yield.

MOENCH; TAPETUM; ARABIDOPSIS; POPULATION; PROTEIN; PLANTS AB Sorghum (Sorghum bicolor L. Moench) is one of the most important grain crops in the world. The nuclear male sterility (NMS) trait, which is caused by mutations on the nuclear gene, is valuable for hybrid breeding and genetic studies. Several NMS mutants have been reported previously, but none of them were well characterized. Here, we present our detailed morphological characterization of a new and easily recognizable NMS sorghum mutant male sterile 8 (ms8) isolated from an elite inbred BTx623 mutagenized by ethyl methane sulfonate (EMS). Our results show that the ms8 mutant phenotype was caused by a mutation on a single recessive nuclear gene that is different from all available NMS loci reported in sorghum. In fertile sorghum plants, yellow anthers appeared first during anthesis, while in the ms8 mutant, white hairy stigma emerged first and only small white anthers were observed, making ms8 plants easily recognizable when flowering. The ovary development and seed production after manual pollination are normal in the ms8 mutant, indicating it is female fertile and male sterile only. We found that ms8 anthers did not produce pollen grains. Further analysis revealed that ms8 anthers were defective in tapetum development, which led to the arrest of pollen formation. As a stable male sterile mutant across different environments, greenhouses, and fields in different locations, the ms8 mutant could be a useful breeding tool. Moreover, ms8 might be an important for elucidating male gametophyte development in sorghum and other plants.

TI Development of a Feature and Template-Assisted Assembler and Application to the Analysis of a Foot-and-Mouth Disease Virus Genotyping Microarray SO PLOS ONE LA English DT Article ID SWINE AB Several RT-PCR and genome sequencing strategies exist for the resolution of Foot-and Mouth Disease virus (FMDV). While these approaches are relatively straightforward, they can be vulnerable to failure due to the unpredictable nature of FMDV genome sequence variations. Sequence independent single primer amplification (SISPA) followed by geno-typing microarray offers an attractive unbiased approach to FMDV characterization. Here we describe a custom FMDV microarray and a companion feature and template-assisted assembler software (FAT-assembler) capable of resolving virus genome sequence using a moderate number of conserved microarray features. The results demonstrate that this approach may be used to rapidly characterize naturally occurring FMDV as well as an engineered chimeric strain of FMDV. The FAT-assembler, while applied to resolving FMDV genomes, represents a new bioinformatics approach that should be broadly applicable to interpreting microarray genotyping data for other viruses or target organisms.

TI High-Throughput Resequencing of Maize Landraces at Genomic Regions Associated with Flowering Time SO PLOS ONE LA English DT Article ID POSTDOMESTICATION SPREAD; READ ALIGNMENT; GENERATION; ENRICHMENT; DIVERSITY; FORMAT; MEXICO; RACES; ZMCCT AB Despite the reduction in the price of sequencing, it remains expensive to sequence and assemble whole, complex genomes of multiple samples for population studies, particularly for large genomes like those of many crop species. Enrichment of target genome regions coupled with next generation sequencing is a cost-effective strategy to obtain sequence information for loci of interest across many individuals, providing a less expensive approach to evaluating sequence variation at the population scale. Here we evaluate amplicon-based enrichment coupled with semiconductor sequencing on a validation set consisting of three maize inbred lines, two hybrids and 19 landrace accessions. We report the use of a multiplexed panel of 319 PCR assays that target 20 candidate loci associated with photoperiod sensitivity in maize while requiring 25 ng or less of starting DNA per sample. Enriched regions had an average on-target sequence read depth of 105 with 98% of the sequence data mapping to the maize 'B73' reference and 80% of the reads mapping to the target interval. Sequence reads were aligned to B73 and 1,486 and 1,244 variants were called using SAMtools and GATK, respectively. Of the variants called by both SAMtools and GATK, 30% were not previously reported in maize. Due to the high sequence read depth, heterozygote genotypes could be called with at least 92.5% accuracy in hybrid materials using GATK. The genetic data are congruent with previous reports of high total genetic diversity and substantial population differentiation among maize landraces. In conclusion, semiconductor sequencing of highly multiplexed PCR reactions is a cost-effective strategy for resequencing targeted genomic loci in diverse maize materials.

TI Spatial Pattern and Scale Influence Invader Demographic Response to Simulated Precipitation Change in an Annual Grassland Community SO PLOS ONE LA English DT Article ID EXPERIMENTAL PLANT-COMMUNITIES; BIOLOGICAL INVASIONS; CLIMATE-CHANGE; CALIFORNIA; IMPACTS; POPULATIONS; COMPETITION; PLASTICITY; RAINFALL; DENSITY AB It is important to predict which invasive species will benefit from future changes in climate, and thereby identify those invaders that need particular attention and prioritization of management efforts. Because establishment, persistence, and spread determine invasion success, this prediction requires detailed demographic information. Explicit study of the impact of pattern on demographic response is particularly important for species that are naturally patchy, such as the invasive grass, Aegilops triuncialis. In the northern California Coast Range, where climate change may increase or decrease mean annual rainfall, we conducted a field experiment to understand the interaction of climate change and local-scale patterning on the demography of A. triuncialis. We manipulated precipitation (reduced, ambient, or augmented), seed density, and seeding pattern. Demographic and environmental data were collected for three years following initial seeding. Pattern and scale figure prominently in the demographic response of A. triuncialis to precipitation manipulation. Pattern interacts with precipitation and seeding density in its influence on per-plant seed output. Although per-plot seed production was highest when seeds were not aggregated, per-plant seed output was higher in aggregated patches. Results suggest aggregation of invasive A. triuncialis reduces the detrimental impact of interspecific competition in its invaded community, and that interspecific competition per se has a stronger impact than intraspecific competition.

The incubation period of sheep scrapie is strongly influenced by polymorphisms at positions 136, 154, and 171 of a sheep's normal cellular prion protein (PrPC). Chymotrypsin was used to digest sheep recombinant PrP to identify a set of characteristic peptides [M(132)LGSXMSRPLI.41 (X = A or V), Y153X-ENMY158 (X,= H or R), and Y166RPVDX-Y-172 (X = H, K, Qi or R)] that could be used to detect and quantitate polymorphisms at positions 136, 154, and 171 of sheep PrPc or PrPs`. These peptides were used to develop a multiple reaction monitoring method (MRM) to detect the amounts of a particular polymorphism in a sample of PrPSc isolated from sheep heterozygous for their PrPC proteins. The limit of detection for these peptides was less than 50 attomole. Spinal cord tissue from heterozygous (ARQ/VRQ_or ARH/ARQ) scrapie-infected Rasa Aragonesa sheep was analyzed using this MRM method. Both sets of heterozygotes show the presence of both polymorphisms in PrPSc. This was true for samples containing both proteinase K (PK)-sensitive and PK-resistant PrPs` and samples containing only the PK-resistant PrPs`. These results, show that heterozygous animals contain PrPs` that is composed of significant amounts of both PrP polymorphisms.

Matsum. & Nakai] is an economically important crop with an attractive ripe fruit that has colorful flesh. Fruit ripening is a complex, genetically programmed process. Results: In this study, a comparative transcriptome analysis was performed to identify the regulators and pathways that are involved in the fruit ripening of pale-yellow-flesh cultivated watermelon (COS) and red-flesh cultivated watermelon (LSW177). We first identified 797 novel genes to extend the available reference gene set. Second, 3958 genes in COS and 3503 genes in LSW177 showed at least two-fold variation in expression, and a large number of these differentially expressed genes (DEGs) during fruit ripening were related to carotenoid biosynthesis, plant hormone pathways, and sugar and cell wall metabolism. Third, we noted a correlation between ripening-associated transcripts and metabolites and the key function of these metabolic pathways during fruit ripening. Conclusion: The results revealed several ripening-associated actions and provide novel insights into the molecular mechanisms underlying the regulation of watermelon fruit ripening.

TI Host plant species determines symbiotic bacterial community mediating suppression of plant defenses SO SCIENTIFIC REPORTS LA English DT Article ID COLORADO POTATO BEETLE; LEPTINOTARSA-DECEMLINEATA; GEOGRAPHIC POPULATIONS; SECRETED BACTERIA; SALICYLIC-ACID; GUT MICROBES; GYPSY-MOTH; CROSS-TALK; INSECT; RESISTANCE AB Herbivore associated bacteria are vital mediators of plant and insect interactions. Host plants play an important role in shaping the gut bacterial community of insects. Colorado potato beetles (CPB; Leptinotarsa decemlineata) use several Solanum plants as hosts in their natural environment. We previously showed that symbiotic gut bacteria from CPB larvae suppressed jasmonate (JA)-induced defenses in tomato. However, little is known about how changes in the bacterial community may be involved in the manipulation of induced defenses in wild and cultivated Solanum plants of CPB. Here, we examined suppression of JA-mediated defense in wild and cultivated hosts of CPB by chemical elicitors and their symbiotic bacteria. Furthermore, we investigated associations between the gut bacterial community and suppression of plant defenses using 16 S rRNA amplicon sequencing. Symbiotic bacteria decreased plant defenses in all Solanum hosts and there were different gut bacterial communities in CPB fed on different host plants. When larvae were reared on different hosts, defense suppression differed among host plants. These results demonstrate that host plants influence herbivore gut bacterial communities and consequently affect the herbivore's ability to manipulate JA-mediated plant defenses. Thus, the presence of symbiotic bacteria that suppress plant defenses might help CPB adapt to host plants. C1 [Chung, Seung Ho] Cornell Univ, Dept Entomol, Ithaca, NY 14853 USA.

SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE cotton; leaf shape; okra; gene cloning ID ELLIPTIC FOURIER DESCRIPTORS; OKRA LEAF; DIFFERENTIAL EXPRESSION; LOW-TEMPERATURE; DIPLOID COTTON; CRUMPLE-VIRUS; HOMEOBOX GENE; ARBOREUM L; MORPHOLOGY; POPULATION AB Leaf shape varies spectacularly among plants. Leaves are the primary source of photoassimilate in crop plants, and understanding the genetic basis of variation in leaf morphology is critical to improving agricultural productivity. Leaf shape played a unique role in cotton improvement, as breeders have selected for entire and lobed leaf morphs resulting from a single locus, okra (L-D-1), which is responsible for the major leaf shapes in cotton. The L-D-1 locus is not only of agricultural importance in cotton, but through pioneering chimeric and morphometric studies, it has contributed to fundamental knowledge about leaf development. Here we show that an HD-Zip transcription factor homologous to the LATE MERISTEM IDENTITY1 (LMI1) gene of Arabidopsis is the causal gene underlying the L-D-1 locus. The classical okra leaf shape allele has a 133-bp tandem duplication in the promoter, correlated with elevated expression, whereas an 8-bp deletion in the third exon of the presumed wild-type normal allele causes a frame-shifted and truncated coding sequence. Our results indicate that subokra is the ancestral leaf shape of tetraploid cotton that gave rise to the okra allele and that normal is a derived mutant allele that came to predominate and define the leaf shape of cultivated cotton. Virus-induced gene silencing (VIGS) of the LMI1-like gene in an okra variety was sufficient to induce normal leaf formation. The developmental changes in leaves conferred by this gene are associated with a photosynthetic transcriptomic signature, substantiating its use by breeders to produce a superior cotton ideotype.

This study aimed to reduce the knowledge gap between edge-of-field and larger agricultural watersheds. Nutrients and sediment transport and transformation at two small agricultural watersheds, Little River Ditches Basin (LRDB) and Lower St. Francis Basin (LSFB), in Northeast Arkansas, were evaluated. Flow, nutrients, and sediment were measured at 3-5 instream locations in these two contrasting watersheds. These watersheds differed in primary crop, soil type, and size. Differences in sediment and nutrients loads were measured between the two watersheds primarily due to differences in cropping practices and soil type. LSFB was dominated by rice farms and had more pollutant load per unit area but lower concentrations for all measured parameters except nitrate, whereas LRDB was dominated by cotton farms and had less pollutant load per unit area but higher concentrations. Turbidity increased considerably at LSFB, but it did not increase or decrease at LRDB as water traveled downstream. The median nitrate-N concentration at LRDB increased from 1.64 to 2.34 mg L-1 as watershed size increased, in contrast to no increase at LSFB. Total phosphorus (TP) and soluble reactive phosphorus (SRP) concentrations remained constant, but ammonium-N decreased as the water traveled downstream in both watersheds. Nitrate-N were high in spring and late fall at both watersheds. The annual loss of nitrate-N was 9.6 and 8.6 kg ha(-1), sediment was 1604 and 1958 kg ha(-1), and SRP was 0.8 and 0.9 kg ha(-1), respectively from LRDB and LSFB. Source control in spring and late fall could be more effective in reducing agricultural pollution. Published by Elsevier B.V.

TI Reconciling opposing soil processes in row-crop agroecosystems via soil functional zone management SO AGRICULTURE ECOSYSTEMS & ENVIRONMENT LA English DT Article DE Ecological intensification; Nitrogen; Soil carbon; Soil organic matter; Spatial heterogeneity; Tillage ID DIFFERENT TILLAGE SYSTEMS; ORGANIC-MATTER DYNAMICS; RIDGE-TILLAGE; NO-TILLAGE; CONSERVATION AGRICULTURE; CARBON ACCUMULATION; PHYSICAL-PROPERTIES; MICROBIAL BIOMASS; NITROGEN UPTAKE; ENZYME-ACTIVITY AB Sustaining soil productivity in agricultural systems presents a fundamental agroecological challenge: nutrient provisioning depends upon aggregate turnover and microbial decomposition of organic matter (SOM); yet to prevent soil depletion these processes must be balanced by those that restore nutrients and SOM (soil building processes). These nutrient provisioning and soil building processes are inherently in conflict; management practices that create spatial separation between them may enable each to occur effectively within a single growing season, thereby supporting high crop yield while avoiding soil depletion. Soil functional zone management (SFZM), an understudied but increasingly adopted strategy for annual row-crop production, may help meet this agroecological challenge by creating spatial heterogeneity in biophysical conditions between crop rows and inter-rows. However, the process-level effects of this spatial heterogeneity on nutrient provisioning and soil building processes have not been characterised. We assessed the magnitude and spatial distribution of nutrient provisioning and soil building processes in model SFZM (ridge tillage) and conventional tillage (chisel plough) systems in four US states encompassing a major global agricultural production region. For soil building we measured bulk density, aggregation and permanganate oxidisable carbon (PDXC); for nutrient provisioning we measured microbial decomposition activity, nutrient mineralisation and plant-available nitrogen. After two years, PDXC increased under ridge tillage (0-20 cm depth) compared with chisel plough. Ridge tillage also enhanced nutrient provisioning processes in crop rows, increasing plant-available nitrogen in synchrony with maize peak nitrogen demand. Structural equation modelling revealed that improvement in soil building processes under ridge tillage caused rapid enhancement of nutrient provisioning processes in SOM-poor soils. Increases in crop row PDXC stimulated microbial decomposition activity, which was associated with increased plant-available nitrogen during the phase of maize peak nitrogen demand. The decimetre-scale spatial heterogeneity created by ridge tillage enables reconciliation of nutrient provisioning and soil building processes in row-crop agroecosystems. In doing so, ridge tillage promotes critical soil processes necessary for increasing the range of ecosystem services provided by intensive production systems. SFZM approaches may have particular value in regions with SOM-poor soils, which would benefit from rapid increases in surface organic carbon. Also, by concentrating and promoting nutrient provisioning processes around crop roots during crop peak nitrogen demand, ridge tillage may enhance nitrogen-use efficiency and reduce current fertiliser requirements.

Pestivirus strains exist as quasispecies (swarms of individual viruses) in infected animals and the viral populations making up the quasispecies differ widely in size and diversity in each animal. In the present study the viral quasispecies circulating in persistently infected (PI) calves, generated and maintained under experimental conditions using two different 'HoBP-like strains, was observed over time. An increase in genetic variability and the development of certain mutations was observed over time. Mutations observed included the loss of a putative N -linked glycosylation site in the E2 region and the change of specific residues in El /E2. It is hypothesized that these changes may be the results on continued adaption of the pestivirus to individual hosts. This is the first study characterizing variation in the viral swarms of animals persistently infected with HoBi-like viruses over time. Studies of the shifts in PI viral swarms will contribute to our understanding of the host and viral mechanisms that function in the maintenance of pestivirus persistent infections.

In this study, PUL solutions containing NaCl or Na3C6H5O7 at different concentrations were electrospun. The inclusion of salts interrupted the hydrogen bonding and altered solution properties, such as viscosity, electric conductivity, and surface tension, as well as physical properties of fibers thus obtained, such as appearance, size, and melting point. The exogenous Na+ associated to the oxygen in the C-6 position of PUL as suggested by FTIR measurement and was maintained during electrospinning. Bead-free PUL fibers could be electrospun from PUL solution (8%, w/v) in the presence of a 0.20MNaCl (124 +/- 34 nm) or 0.05MNa(3)C(6)H(5)O(7) (154 +/- 36 nm). The further increase of NaCl or Na3C6H5O7 resulted in fibers that were flat with larger diameter sizes and defects. SEM also showed excess salt adhering on the surfaces of PUL fibers. Since most food processing is not carried out in pure water, information obtained through the present research is useful for the development of electrospinning biopolymers for food-grade applications.

This research was conducted near Bristol, SD, in 2010 and 2011. Treatments included three N rates (0, 56, and 112 kg N ha(-1)) applied annually and each N rate replicated four times. Aft er a killing frost, all of the plots were harvested and baled in large round bales in October 2010 and November 2011. An area of about 30 m(2) from each plot was left unharvested to represent storage of standing switchgrass over the winter and to , cellulose, lignin, mineral elements, N, and C. In the first season, storadetermine dry matter yields. Switchgrass was analyzed for hemicellulosege of the fall harvested switchgrass bales numerically increased the concentrations of hemicellulose, lignin, and N. In the second season, they increased significantly. Mineral elements significantly increased in both sampling seasons. Delaying harvest until spring decreased lignin, N, and mineral elements concentration, and increased cellulose and hemicellulose concentrations, but also reduced biomass yield. Results from this study suggest that delaying the switchgrass harvest until spring increased the overall feedstock quality for ethanol production, but yield reductions must be considered to determine the overall economic impact of a delayed harvest.

The annual crop rotation was hairy vetch (Vicia villosa Roth) plus triticale (x Triticosecale Wittm.)-corn (Zea mays L.)-cereal rye (Secale cereale L.)soybean [(Glycine max (L.) Merr.]-winter wheat (Triticum aestivum L.) using a full-entry design. Cover crops were terminated based on growth stages designated Early, Intermediate, or Late. Hairy vetchtriticale and cereal rye biomass production exceeded 5000 kg ha(-1) by Late termination in all site-years. Although hairy vetch-triticale biomass production peaked at early flowering of hairy vetch, control increased as termination was delayed. Hairy vetch regrowth and volunteer hairy vetch in subsequent soybean and winter wheat crops was lower in Late compared to Early termination treatments. Cereal rye biomass increased as termination was delayed but optimal control was achieved with Intermediate termination. Rolling cereal rye Early resulted in tillering and seed production whereas rolling Late allowed kernels to mature. Wheat grain contamination by volunteer hairy vetch ranged from 11 to 29% and by volunteer cereal rye from 3 to 11% at Maryland and Pennsylvania, respectively, demonstrating that minimizing cover crop seed production with strategic termination is critical in rotational no-till.

TI Soil Total Carbon and Crop Yield Affected by Crop Rotation and Cultural Practice SO AGRONOMY JOURNAL LA English DT Article ID NORTHERN GREAT-PLAINS; LONG-TERM TILLAGE; ORGANIC-CARBON; SPRING WHEAT; COVER CROPS; NITROGEN; SYSTEMS; CONSERVATION; INTENSITY; SEQUENCE AB Stacked crop rotations and improved cultural practices have been used to control pests, but their impact on soil total carbon (STC) (soil organic carbon [SOC] + soil inorganic carbon [SIC]) and crop yield are lacking. We evaluated the eff ects of stacked vs. alternate-year rotations and cultural practices on STC at the 0- to 125-cm depth and annualized crop yields from 2005 to 2011 in the northern Great Plains. Stacked rotations were durum (Triticum turgidum L.)-durum-canola (Brassica napus L.)-pea (Pisum sativum L.) (D-D-C-P) and durum-durum-flax (Linum usitatissimum L.)-pea (D-D-F-P). Alternate-year rotations were durum-canola-durum-pea (D-C-D-P) and durum-flax-durum-pea (D-F-D-P). A continuous durum (CD) was used as a reference. Cultural practices were traditional (conventional till, recommended seed rate, broadcast N fertilization, and reduced stubble height) and ecological (no-till, increased seed rate, banded N fertilization, and increased stubble height) treatments. Annualized crop biomass residue returned to the soil and grain yield were greater with D-C-D-P and D-D-C-P than D-D-F-P and greater with the ecological than the traditional practice. The STC concentration increased with depth and was greater with CD and D-C-D-P than D-D-C-P and D-D-F-P in traditional and ecological practices at 20 to 50 cm. At 50 to 88 cm, STC concentration was greater with D-F-D-P than D-D-F-P in the traditional practice. At 0 to 125 cm, STC content was lower with D-D-F-P than other crop rotations. Stacked rotations, especially D-D-F-P, reduced soil C storage and crop yields compared with alternate-year rotations. For enhancing soil C storage and crop yields, alternate-year crop rotations are recommended.

TI LEARNING ABOUT A MOVING TARGET IN RESOURCE MANAGEMENT: OPTIMAL BAYESIAN DISEASE CONTROL SO AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS LA English DT Article DE Bioeconomics; dynamic programming; density projection; disease testing; POMDP; uncertainty ID BOVINE TUBERCULOSIS; ADAPTIVE MANAGEMENT; CATTLE; TRANSMISSION; ERADICATION; DIAGNOSIS; POLICY; PLANT; TESTS AB Resource managers must often make difficult choices in the face of imperfectly observed and dynamically changing systems (e.g., livestock, fisheries, water, and invasive species). A rich set of techniques exists for identifying optimal choices when that uncertainty is assumed to be understood and irreducible. Standard optimization approaches, however, cannot address situations in which reducible uncertainty applies to either system behavior or environmental states. The adaptive management literature overcomes this limitation with tools for optimal learning, but has been limited to highly simplified models with state and action spaces that are discrete and small. We overcome this problem by using a recently developed extension of the Partially Observable Markov Decision Process (POMDP) framework to allow for learning about a continuous state. We illustrate this methodology by exploring optimal control of bovine tuberculosis in New Zealand cattle. Disease testing-the control variable-serves to identify herds for treatment and provides information on prevalence, which is both imperfectly observed and subject to change due to controllable and uncontrollable factors. We find substantial efficiency losses from both ignoring learning (standard stochastic optimization) and from simplifying system dynamics (to facilitate a typical, simple learning model), though the latter effect dominates in our setting. We also find that under an adaptive management approach, simplifying dynamics can lead to a belief trap in which information gathering ceases, beliefs become increasingly inaccurate, and losses abound.

Pinus ponderosa (Pinaceae; subsection Ponderosae) is recognized as a problematic taxon: plastid phylogenies of exemplars were paraphyletic, and mitochondrial phylogeography suggested at least four subdivisions of P. ponderosa. These patterns have not been examined in the context of other Ponderosae species. We hypothesized that putative intraspecific subdivisions might each represent a separate taxon. METHODS: We genotyped six highly variable plastid simple sequence repeats in 1903 individuals from 88 populations of P. ponderosa and related Ponderosae (P. arizonica, P. engelmannii, and P. jeff reyi). We used multilocus haplotype networks and discriminant analysis of principal components to test clustering of individuals into genetically and geographically meaningful taxonomic units. KEY RESULTS: There are at least four distinct plastid clusters within P. ponderosa that roughly correspond to the geographic distribution of mitochondrial haplotypes. Some geographic regions have intermixed plastid lineages, and some mitochondrial and plastid boundaries do not coincide. Based on relative distances to other species of Ponderosae, these clusters diagnose four distinct taxa. CONCLUSIONS: Newly revealed geographic boundaries of four distinct taxa (P. benthamiana, P. brachyptera, P. scopulorum, and a narrowed concept of P. ponderosa) do not correspond completely with taxonomies. Further research is needed to understand their morphological and nuclear genetic makeup, but we suggest that resurrecting originally published species names would more appropriately reflect the taxonomy of this checkered classification than their current treatment as varieties of P. ponderosa C1 [Willyard, Ann; Cooper, Blake; Douglas, Connor; Finch, Kristen; Karemera, Hassani H.; Lefler, Julia; Lea, Payton; Wofford, Austin] Hendrix Coll, 1600 Washington Ave, Conway, AR 72032 USA.

To investigate differences in levels of plasma trans fatty acids (TFAs) and a broad set of other markers for cardiovascular disease (CVD) risk in the US adult population between 1999-2000 and 2009-2010. Methods. Using a nationally representative sample of US adults aged 20 years and older from the 1999-2000 and 2009-2010 waves of the National Health and Nutrition Examination Survey, regression models were estimated to compare levels of TFAs and other markers for CVD risk over time. Results. Significant declines in levels of plasma TFAs and improvements in a variety of other markers for CVD risk were observed in the US adult population. Conclusions. Between the 2 time points, 1999-2000 and 2009-2010, there were substantial decreases in TFA levels and improvements in several other important cardiovascular health indicators in US adults.

TI Thermal source Fourier transform infrared microtomography applied to Arctic sea ice diatoms SO ANALYST LA English DT Article ID ALGAE; GROWTH; PHYTOPLANKTON; SPECTROSCOPY; IRRADIANCE; ALLOCATION; RESOLUTION; COMMUNITY; SYSTEM; LIPIDS AB We have used thermal source Fourier Transform Infrared (FTIR) microtomographic imaging to compare sea ice diatoms growing under different light conditions. A prototype tomography accessory was designed to have sufficient degrees of freedom to align any tilted cylindrical sample relative to the axis of rotation, minimizing the off-axis path traced during rotation. The lightweight device rests on the motorized stage to position the sample in the field-of-view and enable mosaic imaging. Reconstruction routines were tested with simulated and real phantoms, to assess limitations in the Radon back-projection method employed. The distribution and abundance of biochemicals is analysed for targets larger than a single FPA tile. Two and three dimensional (2D and 3D) FTIR spectrochemical images were obtained with a Focal Plane Array (FPA, nominal 1.1 mu m pixel edges) for phantoms (polystyrene beads in polyvinyl alcohol matrix) and diatom cells harvested from land fast, first-year ice sites in Resolute Passage (74 43.628'N; 95 33.330'W) and Dease Strait (69(circle) 1.11'N; 105(circle) 21.29'W), Nunavut, Canada. The analysis of relative concentrations of organic matter within the encapsulating silica frustules of diatoms is important for a better understanding of both the physiological state and the individual cellular response to environmental pressures. Analysis of 3D FTIR images of Nitzschia frigida collected from beneath high (17-19 cm) and low (3-7 cm) snow depth revealed higher concentrations of lipids in diatoms collected under low snow cover, uniquely based on spectroscopically determined total 3D cell volume and biochemical content.

Larvae live among and ingest bacteria, which are digested via the combined activity of digestive enzymes, lysozyme, and antimicrobial effectors. Some bacteria resist digestion and subsequent proteolytic processes that occur during metamorphosis, and are carried trans-stadially. Adult house flies ingest bacteria directly from septic substrates or indirectly via self-grooming. Ingested bacteria also face digestion in adults; nonetheless, some microbes not only survive, but proliferate and exchange genetic material. The interaction between adult flies and bacteria is critical in determining vector potential. If the fly is ineffective at eliminating ingested microbes, they can be disseminated in excreta. Unlike larvae, adult house flies are highly mobile, synanthropic, and gregarious, moving indiscriminately between septic environments and domestic locations. Flies can travel miles between sites, dispersing pathogens and their antibiotic-resistance and virulence genes. Considered together, these aspects of adult fly biology underlie their role in the epidemiology and ecology of infectious diseases. Studies of house fly biology have fortuitously revealed interesting adaptations to their septic lifestyle that can be exploited in future approaches to fly control and human health. Larval dependence on microbes can be integrated in novel control strategies, which alter habitat microflora. In contrast, larvae can be utilized beneficially to clear manure of pathogens before being used as fertilizer. In addition, house fly defense effectors such as antimicrobial peptides serve as an untapped resource with the potential to generate novel classes of microbicidal therapeutics.

In most cases, the larvae are found feeding on decomposing vertebrate remains; however, some species have specialized to feed on living tissue or can survive on other alternate resources like feces. Because of their affiliation with such septic environments, these insects have close associations with microbes. Historically, a tremendous amount of research focused on these insects due to their veterinary importance. Within the past 40 yr, efforts have expanded this research to include areas such as systems ecology, forensics, and even wound debridement (maggot) therapy. Initial research efforts examining the relationship between microbes and these insects were hampered by the technology available. However, with the advent of high-throughput sequencing and modern molecular techniques, new avenues of research examining these interactions have opened up. The purpose of this article is to highlight the research exploring the interactions between microbes and blow flies with regards to blow fly biology, the application of such information to benefit humanity, and potential future pathways of research.

TI Abundance and Accumulation of Escherichia coli and Salmonella Typhimurium Procured by Male and Female House Flies (Diptera: Muscidae) Exposed to Cattle Manure SO ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA LA English DT Article DE Musca domestica; bacteria acquisition; vector potential ID MUSCA-DOMESTICA L.; FLY; TRANSMISSION; BACTERIA; BEHAVIOR; INSECTS; DEFENSE; O157-H7; FATE; FOOD AB House flies, Musca domestica L., develop within and feed upon microbe-rich substrates such as manure, acquiring and potentially disseminating pathogenic bacteria. Because adult female flies frequent manure due to oviposition or nutrition requirements, we hypothesized females would consume more manure than males even in the presence of additional food sources (e.g. sugar), resulting in measurable differences in bacterial load between sexes. House fly acquisition of bacteria from manure inoculated with GFP-expressing E. coli or Salmonella sp. was examined for both sexes over 24 h in assays where 1) inoculated manure was the only food source and 2) both inoculated manure and sugar water were provided. We conducted assays with mated male and female flies separately to determine sex-specific effects on bacterial acquisition. Over 24 h, bacterial abundance increased in manure inoculated with S. Typhimurium, but not E. coli. In flies, bacterial abundance increased within sex only in S. Typhimurium assays. Overall, female flies harbored more bacteria than males; however, differences in abundance were only significant at early time points. In the E. coli manure-sugar assays, male and female colony-forming units (CFU) abundance differed at 4 and 12 h, while CFU abundance differed at 4 and 12 h in all S. Typhimurium assays. Fly digestive tract observations from manure-sugar assays supported these initial differences especially at 4 h where females contained manure and fly food, while males contained only sugar water. Identifying sex-specific effects on house fly acquisition and carriage of bacteria from manure facilitates risk assessment of pathogen transmission on farms. C1 [Thomson, J.

Montevideo Strains Throughout Horn Fly (Diptera: Muscidae) Larval and Pupal Development SO ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA LA English DT Article DE Haematobia irritans; insect-microbe interaction; clade; bacteria ID DIAPERINUS COLEOPTERA-TENEBRIONIDAE; HAEMATOBIA-IRRITANS DIPTERA; ESCHERICHIA-COLI; STABLE FLIES; FECAL PREVALENCE; LESSER MEALWORM; DAIRY FARMS; HOUSE-FLY; DIVERSITY; SURVIVAL AB Strains of Salmonella enterica can be subdivided into clades that differ in their genetic composition, influencing microbial ecology and bacterial transmission. Salmonella serovar Montevideo strains 1110 and 304, representatives of two different clades, were used to evaluate interactions with the various stages of horn fly development. Sterilized cattle dung was inoculated with Salmonella monocultures, and horn fly larvae were exposed to 10(3), 10(5), and 10(7) colony-forming units (CFU)/g per strain. Salmonella supported horn fly development, and concentration-dependent differences in pupal survival suggested that Salmonella Montevideo 304 impacts adult emergence when larvae are reared in a high concentration. Viable bacteria of each strain were quantified from larvae, pupae, and newly emerged adults. Both strains were cultured from larvae at a mean similar to 10(5), regardless of concentration, and both strains survived pupation. Quantities of Salmonella 1110 were stationary through the midpupal stage, after which quantities declined in pupae reared in 10(5) and increased twofold in pupae reared in 10(7) CFU/g. Quantities of Salmonella 304 remained stationary throughout pupal development when reared in 10(5), yet increased 29-fold when reared in 10(7) CFU/g. At high densities, properties of Salmonella 304 may influence its interaction with horn fly larvae, enabling the bacteria to evade degradation during larval gut histolysis and to subsequently proliferate during the late stages of pupal development. This may account for the observed effect on adult emergence. The Salmonella strains were rarely cultured from newly emerged adults, indicating that transstadial carriage to the adult stage is inefficient.

TI Microbial Communities Associated With Stable Fly (Diptera: Muscidae) Larvae and Their Developmental Substrates SO ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA LA English DT Article DE Stomoxys calcitrans; bacteria; fungi; gregarine; 454 sequencing ID SP-NOV.; FLIES DIPTERA; MUSCA-DOMESTICA; FEEDING SITES; GEN-NOV; BACTERIA; TABANIDAE; MIDGUT; CATTLE; APICOMPLEXA AB Bacteria are essential for stable fly (Stomoxys calcitrans (L.)) larval survival and development, but little is known about the innate microbial communities of stable flies, and it is not known if their varied dietary substrates influence their gut microbial communities. This investigation utilized 454 sequencing of 16S and 18S amplicons to characterize and compare the bacterial and eukaryotic microbial communities in stable fly larvae and their developmental substrates. The microbial community of the third-instar stable fly larvae is unambiguously distinct from the microbial community of the supporting substrate, with bacterial communities from larvae reared on different substrates more similar to each other than to the communities from their individual supporting substrates. Bacterial genera that were more abundant proportionally in larvae compared to their substrates were Erysipelothrix, Dysgonomonas, Ignatzschineria (Gammaproteobacteria), and Campylobacter (Epsilonprotobacteria). The alphaproteobacteria Devosia, Brevundimonas, Sphingopyxix, and Paracoccus were more abundant proportionally in field substrates compared to their larvae. The main genera responsible for differences between the positive and negative field substrates were Dysgonomonas and Proteiniphilum. In contrast to Dysgonomonas, Proteiniphilum was more abundant in substrate than in the larvae. A large number of sequences were assigned to an unclassified protest of the superphylum Alveolata in larvae and their substrate. Microscopy validated these findings and a previously undescribed gregarine (phylum Apicomplexa, class Conoidasida) was identified in stable fly larvae and adults.

TI Interkingdom Cues by Bacteria Associated with Conspecific and Heterospecific Eggs of Cochliomyia macellaria and Chrysomya rufifacies (Diptera: Calliphoridae) Potentially Govern Succession on Carrion SO ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA LA English DT Article DE Interkingdom eavesdropping; quorum sensing; forensic entomology; carrion decomposition; succession ID LUCILIA-SERICATA DIPTERA; BLACK SOLDIER FLY; PHORMIA-REGINA; BLOW FLIES; AGGREGATED OVIPOSITION; CARCASS ATTENDANCE; TISSUE-TYPE; RESPONSES; TEMPERATURE; BLOWFLIES AB Deciphering mechanisms that regulate succession on ephemeral resources is critical for elucidating food web dynamics and nutrient recycling. Blow fly (Diptera: Calliphoridae) colonization and utilization of vertebrate carrion serve as a model for such studies, as they are the primary invertebrates that recycle this ephemeral resource. Initial colonization by blow flies often results in heightened attraction and colonization by competing conspecifics and heterospecifics, thereby regulating associated arthropod succession patterns. We examined the response of Cochliomyia macellaria (F.) and Chrysomya rufifacies (Macquart) to conspecific and heterospecific eggs. Because Ch. rufifacies is facultatively predacious and cannabalistic, we hypothesized that adults would recognize the presence of conspecific and heterospecific eggs, thus avoiding potential predation and competition. Using a Y-tube olfactometer, we measured the residence time response of C. macellaria and Ch. rufifacies to conspecific and heterospecific eggs of three different age classes (fresh to 9-h-old). Fly responses to surface-sterilized eggs and to an aqueous solution containing egg-associated microbes were then examined. High-throughput sequencing was used to survey egg-associated bacteria from both species. We report that C. macellaria and Ch. rufifacies exhibit differential responses to eggs of conspecifics and heterospecifics, which appear to be a result of microbial volatile-related odors. These behaviors likely influence predator-prey interactions between species. Preliminary high-throughput sequencing revealed Ch. rufifacies had a similar egg-associated fauna as C. macellaria, which may serve as a form of camouflage, allowing it to colonize and thereby attract C. macellaria, a common prey for its larvae.

The capacity of the black blow fly, Phormia regina Meigen, to acquire and subsequently deposit bacteria onto baby lettuce leaves was compared with that of the house fly, Musca domestica (L.). Adult P. regina and M. domestica were exposed to green fluorescent protein-tagged Escherichia coli O157:H7-or Salmonella enterica-inoculated manure and then allowed access to the lettuce plants. Bacteria on the plants and flies were assessed by plating and polymerase chain reaction. Although blowflies acquired significantly more E. coli O157:H7 than house flies, there was no significant difference between the deposition of bacteria on lettuce by the two fly species. In contrast, there was no significant difference in the acquisition of S. enterica by the two fly species. However, blow flies deposited more S. enterica onto lettuce than house flies. To more accurately assess transmission parameters, flies were given timed exposure and inoculation periods of 10 and 30 s. Blowflies acquired more E. coli O157: H7 than S. enterica in the both time periods. Flies exposed to manure for 30 s were then tested for deposition by forcing the flies to walk on lettuce leaves. Blow flies deposited comparable amounts of E. coli O157: H7 and S. enterica. Although house flies have historically been implicated in the transmission of human pathogens to food, the data presented suggest that blow flies are more efficient vectors of E. coli O157: H7 and S. enterica to leafy greens than house flies.

Since 2000, assays have been developed to genotype large numbers of single-nucleotide polymorphisms (SNPs) at relatively low cost. The first commercial SNP genotyping chip was released with a set of 54,001 SNPs in December 2007. Over 15,000 genotypes were used to determine which SNPs should be used in genomic evaluation of US dairy cattle. Official USDA genomic evaluations were first released in January 2009 for Holsteins and Jerseys, in August 2009 for Brown Swiss, in April 2013 for Ayrshires, and in April 2016 for Guernseys. Producers have accepted genomic evaluations as accurate indications of a bull's eventual daughter-based evaluation. The integration of DNA marker technology and genomics into the traditional evaluation system has doubled the rate of genetic progress for traits of economic importance, decreased generation interval, increased selection accuracy, reduced previous costs of progeny testing, and allowed identification of recessive lethals.

Formalization of integrative taxonomy in the past decade has provided a framework for using multidisciplinary data to make species delimitation hypotheses more rigorous. We address the current state of integrative taxonomy by using as a case study an international project targeted at resolving three important tephritid species complexes: Bactrocera dorsalis complex, Anastrepha fraterculus complex, and Ceratitis FAR (C. fasciventris, C. anonae, C. rosa) complex. The integrative taxonomic approach has helped deliver significant advances in resolving these complexes: It has been used to identify some taxa as belonging to the same biological species as well as to confirm hidden cryptic diversity under a single taxonomic name. Nevertheless, the general application of integrative taxonomy has not been without issue, revealing challenges that must be considered when undertaking an integrative taxonomy project. Scrutiny of this international case study provides a unique opportunity to document lessons learned for the benefit of not only tephritid taxonomists, but also the wider taxonomic community.

Invasive tree species are a growing ecological concern worldwide, and some of these invasions involve hybridization events pre- or post-introduction. There are 20 hybrid invasive tree taxa in 15 genera (11 plant families) discussed here. When reported, abundance of hybrids comprised 10-100% of an invasion, the remainder being parental taxa. In seven hybrid taxa, researchers identified phenotypes that may make hybrids better invaders. Twelve hybrid tree taxa involved introgression and more hybrids involved all non-native taxa than native x non-native taxa. Three hybrid tree taxa were the result of intentional crosses, and all hybrid taxa involved intentional introduction of either one or more parental taxon or the hybrid itself. The knowledge gaps present in some hybrid tree taxa can weaken our effectiveness in predicting and controlling invasions, as hybrids can add a level of complexity to an invasion by being morphologically cryptic, causing genetic pollution of a native parental taxon, presenting novel genotypes for which there may not be coevolved biological control agents, or evolving adaptive traits through increased genetic variation.

The contents of the molecular species of triacylglycerols in the mushroom lipid extract in decreasing order were: OOP (2.45%), OOO (1.94%), LLP (1.92%), OLP (1.80%), LLO (1.57%), OPP (1.30%), OOL (1.09%), OOS (0.88%), and LLL (0.85%). Forty one molecular species of acylglycerols out of 103 contained fatty acids with odd numbered carbon atoms. The fatty acids with odd numbered carbon atoms were 15: 0, 17: 0, 17: 1, 19: 0, 19: 1, 21: 0, 23: 0 and 25:0. The total content of fatty acids with odd numbered carbon atoms was about 6.6% of all of the fatty acids of the triacylglycerols containing three normal fatty acids, and contents of individual fatty acids with odd numbered carbon atoms were as: 15: 0 (2.76%), 17: 0 (2.13%), 17: 1 (1.35%), 19: 0 (0.20%), 19: 1 (0.17%). The contents of fatty acids with odd numbered carbon atoms in mushroom were high compared to those in higher plants. This is the first report on the molecular species of acylglycerols in mushroom.

Extracts of mushroom fruiting bodies were obtained using hexane and acetonitrile solvents. Acetonitrile extracts of both mushrooms exhibited higher biological activities than hexane extracts. L. tigrinus acetonitrile extract had 39.2% (EC50 value 637.75 mg/L) radical scavenging activity, contained 451 mg AAE (ascorbic acid equivalent)/g sample total phenolics, and showed 9.48 mm diameter zone of inhibition against Staphylococcus aureus. On the other hand, P. djamour acetonitrile extract had 32.8% (EC50 value 762.19 mg/L) scavenging activity, contained 982 mg AAE/g sample total phenolics, and inhibited S. aureus growth with 9.37 mm diameter zone of inhibition. Both hexane extracts did not show any inhibitory effect against the two bacteria used. Collectively, the acetonitrile extracts of L. tigrinus and P. djamour could be valuable resource of antioxidant and anti-S. aureus compounds which we need to isolate, characterize and identify.

Large differences in genome size and karyotype were found between Aphelinus species, which is surprising given the similarity in their morphology and life history. Genome sizes estimated from flow cytometry were larger for species in the A. mali (Haldeman, 1851) complex than those for the species in the A. daucicola Kurdjumov, 1913 and A. varipes (Forster, 1841) complexes. Haploid karyotypes of the A. daucicola and A. mali complexes comprised five metacentric chromosomes of similar size, whereas those of the A. varipes complex had four chromosomes, including a larger and a smaller metacentric chromosome and two small acrocentric chromosomes or a large metacentric and three smaller acrocentric chromosomes. Total lengths of female haploid chromosome sets correlated with genome sizes estimated from flow cytometry. Phylogenetic analysis of karyotypic variation revealed a chromosomal fusion together with pericentric inversions in the common ancestor of the A. varipes complex and further pericentric inversions in the clade comprising Aphelinus kurdjumovi Mercet, 1930 and Aphelinus hordei Kurdjumov, 1913. Fluorescence in situ hybridization with a 28S ribosomal DNA probe revealed a single site on chromosomes of the haploid karyotype of Aphelinus coreae Hopper & Woolley, 2012. The differences in genome size and total chromosome length between species complexes matched the phylogenetic divergence between them.

It is a major public health problem in many countries around the world. Over the years various methods have been used with an effort to try and control iron-deficiency anemia. However, there has only been a marginal reduction in the global prevalence of anemia. Why is this so? Iron and zinc are essential trace elements for humans. These metals influence the transport and absorption of one another across the enterocytes and hepatocytes, due to similar ionic properties. This paper describes the structure and roles of major iron and zinc transport proteins, clarifies iron-zinc interactions at these sites, and provides a model for the mechanism of these interactions both at the local and systemic level. This review provides evidence that much of the massive extent of iron deficiency anemia in the world may be due to an underlying deficiency of zinc. It explains the reasons for predominance of cellular zinc status in determination of iron/ zinc interactions and for the first time thoroughly explains mechanisms by which zinc brings about these changes.

The objective of the present study was to identify quantitative trait loci (QTLs) for 100-seed weight by using 169 recombinant inbred lines (RILs) derived from the cross Williams 82xPI 366121. The parental lines and RILs were grown for four consecutive years (2012-15) in the field. The seeds were harvested after maturity, dried and used to measure 100-seed weight. Analysis of variance indicated significant differences among the RILs for 100-seed weight. The environment had significant effect on seed-weight expression as indicated by the genotypexenvironment interaction. QTL analysis employing inclusive composite interval mapping of additive QTLs implemented in QTL IciMapping (Version 4.1) identified nine QTLs (LOD >3) on chromosomes 1, 2, 6, 8, 13, 14, 17 and 20. The individual QTLs explained phenotypic variation in the range 6.1-12.4%. The QTLs were detected in one or two environments, indicating major influence of the growing environment on seed-weight expression. Four QTLs identified in this study, qSW-02_1, qSW-06_1, qSW-13_1 and qSW-14_1, were found to be new QTLs. The findings of the study may be helpful to reveal the molecular genetic basis of the seed-weight trait in soybean.

The prepared catalysts were used to evaluate catalytic pyrolysis for the conversion of Eucalyptus urophylla to fuels and chemicals, specifically aromatic hydrocarbons, by using a micro-scale pyrolysis reactor coupled with GC-MS. Two different biomass-to-catalyst ratios (1: 5 and 1: 10 w/w) were studied. The catalyst prepared with Ga by total ion exchange (Ga-HZSM-5 B, approximate to 7 wt% Ga) yielded the highest amount of aromatic hydrocarbons, whereas the catalysts modified with Ni produced the lowest yield of aromatic hydrocarbons. A correlation between the methane yield and benzene and p-xylene selectivity was found for the catalysts, which was observed mainly for the Ni-, Zn-, and Ga-Ni-modified catalysts. The Ga-modified catalysts were the most selective for xylenes, whereas the Ni-based catalysts were the most selective for benzene production with a concurrent increase in methane production. The Zn-modified catalysts were the most selective for toluene production.

An understanding of their bioaccessibility and bioavailability is essential for the elucidation of their health benefits. Before reaching circulation and exerting bioactions in target tissues, numerous interactions take place before and during digestion with either the plant or host's macromolecules that directly impact the organism and modulate their own bioaccessibility and bioavailability. The present work is focused on the gastrointestinal (GI) interactions that are relevant to the absorption and metabolism of PCs and how these interactions impact their pharmacokinetic profiles. Non-digestible cell wall components (fiber) interact intimately with PCs and delay their absorption in the small intestine, instead carrying them to the large intestine. PCs not bound to fiber interact with digestible nutrients in the bolus where they interfere with the digestion and absorption of proteins, carbohydrates, lipids, cholesterol, bile salts and micronutrients through the inhibition of digestive enzymes and enterocyte transporters and the disruption of micelle formation. PCs internalized by enterocytes may reach circulation (through transcellular or paracellular transport), be effluxed back into the lumen (P-glycoprotein, P-gp) or be metabolized by phase I and phase II enzymes. Some PCs can inhibit P-gp or phase I/II enzymes, which can potentially lead to drug-nutrient interactions. The absorption and pharmacokinetic parameters are modified by all of the interactions within the digestive tract and by the presence of other PCs. Undesirable interactions have promoted the development of nanotechnological approaches to promote the bioaccessibility, bioavailability, and bioefficacy of PCs. C1 [Dominguez-Avila, J.

Design: Longitudinal pilot study. Setting: Large, university-based, urban Midwestern U.S. medical center. Participants: Convenience sample of 32 African American women with high-risk pregnancies seeking care at an urban maternal-fetal medicine clinic. Methods: Nonfasting venous blood was collected in the second and third trimesters to assess iron status, hepcidin, and systemic inflammation. Anthropometric and survey data were obtained via self-report. Descriptive statistics were calculated from these data, and changes in the clinical parameters between the second and third trimesters were evaluated via paired t tests. Associations among demographic, reproductive, anthropometric, inflammatory, and iron-related parameters were also assessed in each trimester. Results: The mean age of participants was 28.3 (+/- 6.8) years, and mean prepregnancy body mass index was 31.9 (+/- 10.7) kg/m(2). In the longitudinal analysis, significant (p < .05) declines in serum iron, ferritin, transferrin saturation, and C-reactive protein were observed between the second and third trimesters. There was no statistically significant change in hepcidin between trimesters. When using a ferritin level cut-point of less than 15 ng/ml and soluble transferrin receptor level of greater than 28.1 nmol/L, 48% of the participants (14 of 29) were classified with iron deficiency in the third trimester. Conclusion: In this pilot study, iron deficiency was prevalent among a small cohort of African American women with high-risk pregnancies. Hepcidin concentrations were greater than previously reported in healthy, pregnant, primarily White women, which suggests decreased iron bioavailability in this high-risk group.

Identification of host genetic factors that enable selection for improved performance during PRRS virus (PRRSV) infection would reduce the impact of this disease on animal welfare and production efficiency. We conducted genomewide association study (GWAS) analyses of data from 13 trials of approximately 200 commercial crossbred nursery-age piglets that were experimentally infected with 1 of 2 type 2 isolates of PRRSV (NVSL 97-7985 [NVSL] and KS2006-72109 [KS06]). Phenotypes analyzed were viral load (VL) in blood during the first 21 d after infection (dpi) and weight gain (WG) from 0 to 42 dpi. We accounted for the previously identified QTL in the GBP5 region on SSC4 in our models to increase power to identify additional regions. Many regions identified by single-SNP analyses were not identified using Bayes-B, but both analyses identified the same regions on SSC3 and SSC5 to be associated with VL in the KS06 trials and on SSC6 in the NVSL trials (P < 5 x 10(-6)); for WG, regions on SSC5 and SSC17 were associated in the NVSL trials (P < 3 x 10(-5)). No regions were identified with either method for WG in the KS06 trials. Except for the GBP5 region on SSC4, which was associated with VL for both isolates (but only with WG for NVSL), identified regions did not overlap between the 2 PRRSV isolate data sets, despite high estimates of the genetic correlation between isolates for traits based on these data. We also identified genomic regions whose associations with VL or WG interacted with either PRRSV isolate or with genotype at the SSC4 QTL. Gene ontology (GO) annotation terms for genes located near moderately associated SNP (P < 0.003) were enriched for multiple immunologically (VL) and metabolism-(WG) related GO terms. The biological relevance of these regions suggests that, although it may increase the number of false positives, the use of single-SNP analyses and a relaxed threshold also increased the identification of true positives. In conclusion, although only the SSC4 QTL was associated with response to both PRRSV isolates, genes near associated SNP were enriched for the same GO terms across PRRSV isolates, suggesting that host responses to these 2 isolates are affected by the actions of many genes that function together in similar biological processes.

Sixty mixed sex piglets from 10 sows (n = 6 piglets/sow) were weaned (18.8 +/- 0.8 d of age) and then herded up ramps into 1 of 2 simulated transport trailers in either TN (28.8 +/- 0.2 degrees C) or HS (cyclical 32 to 37 degrees C) conditions where they remained for 12 h. During the 12 h of simulated transport, fans were used to simulate air movement through the trailer, feed and water were withheld, and rectal temperature (TR) was measured hourly. Following the 12 h simulated transport, piglets were unloaded from the trailer, weighed, and then housed individually in TN conditions [28.5 +/- 0.1 degrees C; 29.1 +/- 0.1% relative humidity (RH)] and assigned to 1 of 3 dietary treatments balanced by weaning weight, sex, sow, and transport environment. Treatments were dietary antibiotics [A; n = 20 piglets; 5.5 +/- 0.2 kg BW; chlortetracycline (400 g/ton) + tiamulin (35 g/ton)], no dietary antibiotics (NA; n = 20 piglets; 5.6 +/- 0.2 kg BW), or 0.20% L-glutamine (GLU; n = 20 piglets; 5.6 +/- 0.2 kg BW) fed for 14 d. During the diet treatment period, feed intake (FI), BW, and behaviors were monitored daily. At the conclusion of the diet treatment period, all piglets were euthanized and intestinal samples were collected for histology. The TR and post-transport BW loss were increased in HS (40.7 degrees C and 0.43 kg, respectively) compared to TN-exposed (39.2 degrees C and 0.27 kg, respectively) piglets during simulated transport. Throughout the 14 d dietary treatment phase, FI was greater overall (P < 0.01; 60.3%) in GLU compared to A and NA pigs, and tended to be greater (37.7%) in A compared to NA pigs. BW was greater overall (P < 0.01; 8.7%) in GLU and A compared to NA pigs, but no differences were detected between A and GLU pigs. Lying behavior was greater (P = 0.05; 11.7%) in NA compared to A and GLU piglets in the first 2 d following simulated transport. The villus height to crypt depth ratio was greater (P < 0.05) in the duodenum (12.1%) and jejunum (12.8%) for A and GLU compared to NA pigs, and greater in the ileum (15.6%) for GLU compared to A and NA pigs. In summary, withholding dietary antibiotics after weaning and transport can negatively affect piglet productivity and measures of intestinal morphology compared to dietary antibiotic administration and L-glutamine provision.

TI Factors affecting fecal egg counts in periparturient Katahdin ewes and their lambs SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE gastrointestinal nematodes; periparturient rise; sheep ID HAEMONCHUS-CONTORTUS; GASTROINTESTINAL NEMATODES; ANTHELMINTIC RESISTANCE; UNITED-STATES; MERINO SHEEP; GOAT FARMS; MONEPANTEL; EFFICACY; PREVALENCE; SELECTION AB Selection for low fecal egg counts (FEC) can be used to genetically enhance resistance to gastrointestinal nematode parasites in growing lambs, thereby reducing the frequency of use of anthelmintics, facilitating marketing of organic lamb, and reducing the risk of development of anthelmintic resistance by the parasite. Recording of FEC in lambs has, therefore, been incorporated into several national sheep genetic evaluation programs. Ewes in late gestation and early lactation are also vulnerable to parasite infection and commonly experience a periparturient rise in FEC. This study was designed to assess factors associated with the periparturient rise in FEC in Katahdin ewes and associated changes in FEC in their lambs. Data came from 1,487 lambings by 931 Katahdin ewes from 11 farms in the Eastern United States. Fecal egg counts were measured in ewes at approximately 0, 30, and 60 d postpartum and in their lambs at approximately 60, 90, and 120 d of age. Approximately 1,400 lambs were evaluated at each measurement age. Data were analyzed separately for ewes and lambs and also initially analyzed separately for each measurement time. Repeated-measures analyses were then used to evaluate responses across measurement times. In ewes, FEC peaked at approximately 28 d postpartum, and we concluded that informative periparturient FEC could be obtained from 1 wk before until approximately 5 wk after lambing. Yearling ewes had higher FEC than adult ewes (P < 0.01), and ewes that nursed twin or triplet lambs had higher FEC than ewes that nursed single lambs (P < 0.01). In lambs, FEC increased through approximately 120 d of age. Lambs from yearling ewes and lambs nursed in larger litters were, like their dams, at greater risk of parasitism (P < 0.05). Ewes and lambs in these groups would benefit from enhanced monitoring of parasite loads at lambing and in early lactation. Correlations (r) between FEC in lambs at 90 d of age and FEC in ewes at 0, 30, and 60 d postpartum of 0.05 to 0.09 (P <= 0.05) support the presence of a genetic relationship between these 2 indicators of parasite resistance.

Brahman cows (n = 96; 48 were stressed by transportation at 5 stages of gestation and 48 were controls) produced a calf crop of 85 calves. All bulls (n = 46) from this calf crop were electroejaculated every 2 wk beginning at a scrotal circumference of 24 cm until sexual maturity (SM; i. e., 500 million sperm/ejaculate). The initial 11 control and 12 PNS bulls to reach SM were selected for the experiment. Within 7-21 d after reaching SM, bulls were fitted with jugular cannulas, from which blood samples were collected at 15-min intervals for 6 h prior to exogenous GnRH administration (10 ng/kg BW; i. v.) and for 6 h after GnRH. Serum concentrations of LH, testosterone, and cortisol were determined by RIA. Age and body weight did not differ (P > 0.1) between PNS and control bulls at the time of the experiment. All bulls responded similarly to exogenous GnRH, indicating no influence of PNS on LH or testosterone response to GnRH. More (P < 0.01) PNS (9 of 11) than control (3 of 12) bulls exhibited an endogenous pre-GnRH LH pulse, and more (P = 0.02) PNS (9 of 11) than control bulls (4 of 12) exhibited a pre-GnRH testosterone response to LH. The average concentration of testosterone during the 60 min (time -60, -45, -30, -15, and 0 min relative to GnRH) immediately preceding GnRH, tended to be greater (P = 0.07) in PNS (1.46 +/- 0.30 ng/mL) than control (0.68 +/- 0.28 ng/mL) bulls. During that time span serum cortisol was lower (P < 0.01) in PNS (4.00 +/- 0.91 ng/mL) than control (7.8 +/- 0.87 ng/mL) bulls. A treatment by time interaction (P = 0.03) affected testosterone concentrations from time -240 to 360 min relative to GnRH. Results from this study indicate that PNS did not affect pituitary responsiveness to GnRH or testicular responsiveness to GnRH-induced LH secretion. C1 [Littlejohn, B. P.; Roberts, M. C.; Lewis, A.

TI Influence of cow breed type, age and previous lactation status on cow height, calf growth, and patterns of body weight, condition, and blood metabolites for cows grazing bahiagrass pastures SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE Brahman; cow-calf; non-esterified fatty acids; plasma urea N; previous lactation status; romosinuano; sub-tropical ID NONESTERIFIED FATTY-ACIDS; RECIPROCAL-CROSS COWS; BEEF-COWS; BRAHMAN COWS; PENSACOLA BAHIAGRASS; FORAGE QUALITY; BOS-INDICUS; MILK-YIELD; ANGUS; CATTLE AB This study was initiated to evaluate performance and patterns of cow traits and blood metabolites of 3 breeds of cows grazing bahiagrass (Paspalum notatum Flugge) pastures in central Florida. Purebred cows (n = 411) of either Angus (Bos taurus), Brahman (Bos indicus), or Romosinuano (Bos taurus) breeding, rotationally grazed (moved twice weekly) bahiagrass pastures year-round, and received bahiagrass hay supplemented with molasses and soyhulls or legume hay supplemented with unfortified molasses from October to June each production year. At monthly intervals, all cows were weighed, measured at the hip (HH), scored for BCS, and blood samples collected by jugular puncture from 10 cows per cow breed/block group for plasma urea N (PUN), glucose and non-esterified fatty acids (NEFA). Data were analyzed on cows that calved with a statistical model that included fixed effects of year, cowage, cow breed, month, block, supplement group (n = 2, but not presented), and whether the cow weaned a calf the previous year. Cow was a repeated observation over mo. Three-way interactions involving monthly patterns for cowage x year, year x lactation status the previous year, cowage x cow breed, year x cow breed, and cow breed x lactation status the previous year were significant (P < 0.001) for BW and BCS. The interaction for cowage x month was also significant (P < 0.05) for glucose, and cow breed x month was important (P < 0.01) for PUN, glucose, and NEFA. Important differences included: 1) greater BW and BCS for older cows compared to 3-yr old cows; 2) greater BW and BCS before calving for cows that did not lactate the previous year; 3) PUN levels were above 11 mg/dl except for February, August and September, and was generally greater in tropically adapted breeds; 4) GLU was greatest in Brahman, lowest in Angus, and intermediate in Romosinuano cows; and 5) plasma levels of NEFA escalated at calving and then declined, but Brahman cows maintained greater (P < 0.05) levels from calving until weaning than the other breeds. Cows that lactated the previous year had less NEFA than those that did not lactate. Brahman cows were less fertile than Bos taurus breeds, and weaned heavier calves. C1 [Coleman, S.

Fifty-four barrows weaned at 28 d of age were fed a common starter diet for 7 d, group fed their respective experimental diets for an additional 7 d, and then moved to metabolism crates and individually fed their respective diets for another 10 d. Following this period, a 4-d total fecal and urine collection period was used to determine apparent total tract digestibility (ATTD) of GE and EE and to determine the DE and ME content of each lipid source (11.03 +/- 0.51 kg final BW). Following the last day of fecal and urine collection, pigs were given an oral dose of lactulose and mannitol and fed their respective experimental diets with urine collected for the following 12 h. A subsequent urine collection occurred for 5 h to determine thiobarbituric acid reactive substances (TBARS) and isoprostane (IsoP) concentrations. Following this urine collection, serum was obtained and analyzed for TBARS and endotoxin concentrations. Soybean oil had the greatest (P < 0.05) DE (9,388 kcal/kg) content compared with DCO-1, DCO-2, CWG, and PO (8,001, 8,052, 8,531, and 8,293 kcal/kg lipid, respectively). Energy digestibility was greatest for SO compared with the other lipid sources (P < 0.05). The ATTD of EE averaged 85.0% and varied slightly (84.4 to 85.6%) among treatments. Differences in ME content among lipids were similar to those reported for DE, with ME values for DCO1, DCO-2, CWG, PO, and SO being 7,921, 7,955, 8,535, 8,350, and 9,408 kcal/kg lipid, respectively. Metabolizable energy as a percentage of DE did not differ among lipid sources. Pigs fed lipid diets had greater (P < 0.05) serum TBARS compared with pigs fed the control diet, but no differences were observed in urinary TBARS excretion among the lipid treatments. Urinary IsoP excretion differed among treatments (P < 0.01) but was highly variable (34.0 to 104.6 pg). However, no differences were observed among treatments for the urinary lactulose: mannitol ratio and serum endotoxin. These results indicate that DE and ME content of SO are greater than that of other lipid sources evaluated, but feeding these lipids has no effect on gut integrity while producing variable effects on oxidative stress.

TI Fermentation products as feed additives mitigate some ill-effects of heat stress in pigs SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE antibiotics; fermentation products; heat stress; pigs ID TIGHT JUNCTION PERMEABILITY; DOWN-REGULATION; INTESTINAL INTEGRITY; GENE-EXPRESSION; GROWING PIGS; TEMPERATURE; PROBIOTICS; ALLEVIATE; INCREASE; HYPOXIA AB Heat stress (HS) may result in economic losses to pig producers across the USA and worldwide. Despite significant advancements in management practices, HS continues to be a challenge. In this study, an in-feed antibiotic (carbadox, CBX) and antibiotic alternatives (Saccharomyces cerevisiae [XPC], and Lactobacillus acidophilus [SGX] fermentation products) were evaluated in a standard pig starter diet as mitigations against the negative effects of HS in pigs. A total of 100 gilts were obtained at weaning (6.87 +/- 0.82 kg BW, 19.36 +/- 0.72 d of age) and randomly assigned to dietary treatments (2 rooms/treatment, 2 pens/room, 6 to 7 pigs/pen). After 4 wk of dietary acclimation, half of the pigs in each dietary group (1 room/dietary treatment) were exposed to repeated heat stress conditions (RHS; daily cycles of 19 h at 25 degrees C and 5 h at 40 degrees C, repeated for 9 d), and the remaining pigs were housed at constant thermal neutral temperature (25 degrees C, [NHS]). Pigs subjected to RHS had elevated skin surface temperature (P < 0.05; average 41.7 degrees C) and respiration rate (P < 0.05; 199 breaths per minute (bpm) during HS, and overall reduced (P < 0.05) BW, ADG, ADFI, and G: F regardless of dietary treatment. Independent of diet, RHS pigs had significantly shorter (P < 0.05) jejunum villi on d 3 and d 9 compared to NHS pigs. Heat stress resulted in decreased villus height to crypt depth ratio (V: C) in pigs fed with control diet with no added feed additive (NON) and CBX diets at d 3, whereas the pigs fed diets containing XPC or SGX showed no decrease. Transcriptional expression of genes involved in cellular stress (HSP27, HSP70, HSP90, HIF1A), tight junction integrity (OCLN, CLDN3, CLDN4), and immune response (TNFA, IFNG, and IL8) were measured in the ileum mucosa. Pigs in all dietary treatments subjected to RHS had significantly higher (P < 0.05) transcript levels of HSP27 and HSP90, and an upward trend (P < 0.07) of HSP70 mRNA expression. RHS pigs had higher (P < 0.05) transcript levels of IFNG and CLDN4 in NON diet, TNFA in XPC and CBX diets, and HSP70 in SGX diet compared to the respective diet-matched pigs in the NHS conditions. Neither RHS nor diet affected peripheral natural killer (NK) cell numbers or NK cell lytic activity. In conclusion, pigs subjected to RHS had decreased performance, and supplementation with fermentation products in the feed (XPC and SGX) protected pigs from injury to the jejunum mucosa.

TI Effects of mass airflow rate through an open-circuit gas quantification system when measuring carbon emissions SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE Bos taurus; carbon dioxide; grazing; methane; respiration; ruminant ID METHANE EMISSIONS; ENERGY-EXPENDITURE; BEEF-CATTLE; RUMINANT; MITIGATION; PASTURE; SHEEP AB Methane (CH4) and carbon dioxide (CO2) represent 11 and 81%, respectively, of all anthropogenic greenhouse gas emissions. Agricultural CH4 emissions account for approximately 43% of all anthropogenic CH4 emissions. Most agricultural CH4 emissions are attributed to enteric fermentation within ruminant livestock; hence, the heightened interest in quantifying and mitigating this source. The automated, open-circuit gas quantification system (GQS; GreenFeed, C-Lock, Inc., Rapid City, SD) evaluated here can be placed in a pasture with grazing cattle and can measure their CH4 and CO2 emissions with spot sampling. However, improper management of the GQS can have an erroneous effect on emission estimates. One factor affecting the quality of emission estimates is the airflow rates through the GQS to ensure a complete capture of the breath cloud emitted by the animal. It is hypothesized that at lower airflow rates this cloud will be incompletely captured. To evaluate the effect of airflow rate through the GQS on emission estimates, a data set was evaluated with 758 CO2 and CH4 emission estimates with a range in airflows of 10.7 to 36.6 L/s. When airflow through the GQS was between 26.0 and 36.6 L/s, CO2 and CH4 emission estimates were not affected (P = 0.14 and 0.05, respectively). When airflow rates were less than 26.0 L/s, CO2 and CH4 emission estimates were lower and decreased as airflow rate decreased (P < 0.0001). We hypothesize that when airflow through the GQS decreases below 26 L/s, breath capture was incomplete and CO2 and CH4 emissions are underestimated. Maintaining mass airflow through a GQS at rates greater than 26 L/s is important for producing high quality CO2 and CH4 emission estimates.

We tested mite populations within 28 honey bee colonies on adult bees by a using a powdered sugar shake method. Subsequently, the same colonies were treated with 2.9% oxalic acid and 31.9% sucrose-in-water solution (w/w) four times, with a final varroa treatment using Apistan strips. On average 66.10 +/- 35.23% and 94.64 +/- 9.56% mites were detected using this simple sugar shake method in August and October, 2015. Furthermore, positive correlations were found between relative number of infested honey bees detected by powdered sugar shake and washing bees with alcohol plus soapy water ( r = 0.90 and r = 0.62). Temperature and humidity seems to be crucial in determining the effectiveness of the powdered sugar shake method. For control of the mites, four consecutive OA treatments performed during the winter months in colonies containing capped brood had an average of 228 +/- 226.93, 167 +/- 313.79, 92 +/- 160.50, and 27 +/- 42.19 varroa mortality, respectively. Combination of four successive OA applications by trickling onto adult bees between combs in situ, during warm temperate winter conditions ensured a cumulative efficacy of 98%. Based on this level of mortality, it can be concluded that using the powdered sugar shake method to establish adult bee infestation levels in colonies along with an OA treatment may provide adequate varroa control in certain situations.

Based on theory and experimental studies, overexpression of the photosynthetic enzyme sedoheptulose-1,7-bisphosphatase (SBPase) is expected to enhance C-3 crop photosynthesis and yields. Here we test how expression of the cyanobacterial, bifunctional fructose-1,6/sedoheptulose-1,7-bisphosphatase (FBP/SBPase) affects carbon assimilation and seed yield (SY) in a major crop (soybean, Glycine max). For three growing seasons, wild-type (WT) and FBP/SBPase-expressing (FS) plants were grown in the field under ambient (400 mu mol mol(-1)) and elevated (600 mu mol mol(-1)) CO2 concentrations [CO2] and under ambient and elevated temperatures (+2.7 degrees C during daytime, +3.4 degrees C at night) at the SoyFACE research site. Across treatments, FS plants had significantly higher carbon assimilation (4-14%), V-c,V-max (5-8%), and J(max) (4-8%). Under ambient [CO2], elevated temperature led to significant reductions of SY of both genotypes by 19-31%. However, under elevated [CO2] and elevated temperature, FS plants maintained SY levels, while the WT showed significant reductions between 11% and 22% compared with plants under elevated [CO2] alone. These results show that the manipulation of the photosynthetic carbon reduction cycle can mitigate the effects of future high CO2 and high temperature environments on soybean yield.

The liquefied residue with content of 23.44% from 180 degrees C/7.5 min was used to fibrillate CNCs with dilute alkali (2% NaOH) and hydrogen peroxide (5% H2O2) treatments, followed by ultrasonication for 15 min. The FT-IR spectra and SEM images revealed that the liquefied residue from 180 degrees C/7.5 min exhibited a relatively homogeneous texture and a huge surface with cellulose as core structure. The retained hemicelluloses and other impurities in the liquefied residue were eliminated by 2% NaOH treatment, and the surface and accessibility of the alkali treated sample were significantly increased by 5% H2O2 treatment. The TEM images confirmed the CNCs had an average diameter of 12.59 nm. The CNCs had good thermal stability with a maximum weight loss temperature of 376.5 degrees C.

No. CV-130, PI 675157) is a large-seeded high-oleic virginia-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) that has enhanced Sclerotinia blight and pod rot resistance when compared to the cultivar Jupiter. VENUS is the first high-oleic virginia peanut developed for optimal performance in the southwestern United States, and it was released cooperatively by the USDA-ARS and the Oklahoma Agricultural Experiment Station (OAES) in 2015. VENUS (experimental designation ARSOK-V30B) is the result of a cross between the cultivar Jupiter, a non-high-oleic virginia peanut released by the OAES in 2000, and ARSOK-R2, a high-oleic advanced runner breeding line with resistance to Sclerotinia blight. Tests conducted at three locations across Oklahoma in 2012 to 2014 showed no significant difference between the yields of VENUS and Jupiter. However, VENUS graded significantly higher than Jupiter in two out of three locations. VENUS also has better resistance to Sclerotinia blight and pod rot (61 and 70% less disease, respectively) than Jupiter. Production of VENUS peanut in areas with high Sclerotinia blight and/or pod rot disease pressures will reduce the need for fungicide applications and result in increased profits for producers.

TI Registration of 'Highpro1' Soybean with High Protein and High Yield Developed from a North x South Cross SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article ID SEED PROTEIN AB 'Highpro1' soybean [Glycine max (L.) Merr.]) (Reg. No. CV-521, PI 678444) was developed and jointly released by the USDA Agricultural Research Service and The Ohio Agricultural Research and Development Center in Wooster, OH, as a high-protein high-yielding maturity group (MG) III (relative maturity 3.7) conventional soybean cultivar. Highpro1 is a selection from a cross between a food-grade soybean cultivar, 'Wyandot', from The Ohio State University and a high-protein breeding line, GASF98-114, from University of Georgia Athens. Across 20 environments in the Northern Regional Soybean MG-III Quality Traits Tests, Highpro1 yielded (3746 kg ha(-1)) the same as the mean yield of four high-yielding check cultivars in the tests, and its protein content was much higher than the checks. On a 13% (w/w) moisture basis, Highpro1 produced 401 g kg(-1) seed protein compared with the check cultivars' averages of 344 g kg(-1) seed protein. Across five environments of yield testing in Ohio, this line produced 4% higher seed yield and 45 g kg(-1) higher seed protein content than the early-maturing parental cultivar Wyandot. However, it is 7 d later in maturity with 18 g kg(-1) lower seed oil content than Wyandot. In 2012 Ohio State Soybean Performance Trials, seed yields of Highpro1 were comparable to the yields of high-yield check cultivars of similar maturity and 10% higher than that of Wyandot. Highpro1 is resistant to southern root knot nematode, and it has high level of partial resistance to Phytophthora root and stem rot. C1 [Mian, M. A.

TI Registration of 'Prevail' Hard Red Spring Wheat SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article ID FUSARIUM HEAD BLIGHT; RESISTANCE AB Grower and end-user acceptance of new hard red spring wheat (HRSW; Triticum aestivum L.) cultivars largely depends on satisfactory agronomic performance, end-use quality potential, and disease resistance levels. Additional characteristics, such as desirable plant height, can also contribute to grower acceptance. The objective of this research was to release a short-statured HRSW cultivar with competitive grain yield and acceptable levels of enduse quality characteristics and Fusarium head blight (FHB) resistance. 'Prevail' (Reg. No. CV-1121; PI 672486) HRSW was developed at South Dakota State University (SDSU) and released by the South Dakota Agricultural Experiment Station (SDAES) in early 2014. The cross SD3720/MN98389-A was completed during fall 2002, and the resulting population was advanced via an early-generation bulk-testing program where F-6:8 seed was included in the 2008 preliminary yield trial and the line was designated as SD4178. SD4178 also was tested in the advanced yield trial from 2009 through 2013. Prevail was released primarily for its combination of high yield potential and desirable plant height that is significantly shorter than most other HRSW cultivars developed by the SDSU-HRSW breeding program.

TI Registration of Two Upland Cotton Germplasm Lines Possessing Superior Fiber Quality Traits SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article ID POPULATION AB The upland cotton (Gossypium hirsutum L.) germplasm lines PX06520-42-2-1 (Reg. No. GP-1005, PI 677343) and PX06520-42-2-3 (Reg. No. GP-1006, PI 677344) were jointly released by the USDA-ARS and Cotton Incorporated in 2016. The lines were released to provide broadly adapted, high fiber quality resources for facilitating fiber improvement efforts across the US Cotton Belt. PX06520-42-2-1 and PX06520-42-2-3 originated from the cross SG747/NM49//AGC85/436443, followed by individual plant selection in the F-2, F-3, and F-4 generations. The two best progeny lines, determined from replicated tests conducted at College Station, TX, and Florence, SC, in 2011 and 2012, were entered into the Regional Breeders Testing Network tests across the US upland Cotton Belt in 2013 and 2014. In 2013, both PX06520-42-2-1 and PX06520-42-2-3 were superior to the check cultivars 'DP 393', 'FM 958', and 'SG 105' for fiber length, fiber length uniformity, fiber strength, and short fiber content. In 2014, PX06520-42-2-1 produced a fiber length, fiber length uniformity, and fiber strength that were superior to the five check cultivars DP 393, FM 958, SG 105, 'UA 222', and 'DP 491'. Fiber yield of PX06520-42-2-1 did not differ significantly from any of the five check cultivars used in 2014. The two lines are excellent sources of fiber quality, with acceptable yield potentials that appear to be stable across production environments. C1 [Percy, R.

TI Registration of Perennial Sorghum bicolor x S. propinquum Line PSH12TX09 SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article ID GRAIN CROPS; POPULATION; GROWTH; MAIZE; WHEAT AB A novel sorghum [Sorghum bicolor (L.) Moench x S. propinquum (Kunth) Hitchc.] F-6 recombinant inbred line, PSH12TX09 (GS-784, PI 675359), was identified that successfully overwintered across USDA plant hardiness zones 8a, 8b, and 9a between 2013 and 2015. Prior development from the initial interspecific hybridization through the F 3 generation was done at the USDA-ARS Southern Plains Area Research Center, College Station, TX; further advancement to F-6 was a collaborative effort between Texas A&M University, Texas A&M AgriLife Research, and the USDA-ARS. Winter survival of PSH12TX09 exceeded 90% at three locations in plant hardiness zones 9a, 8b, and 8a in both evaluation years, with no significant differences across locations. PSH12TX09 is significantly taller (>= 60 cm), requires more days to anthesis (>= 16 d), and is smaller in seed size (-66%) than the well-documented sorghum inbred line BTx623. As a highly overwintering genotype, PSH12TX09 may serve as a novel resource to further dissect mechanisms of perennialism as well as develop perennial sorghum germplasm suitable for utilization as grain, forage, and biofuel feedstocks.

TI Genetic Diversity in the Desert Watermelon Citrullus colocynthis and its Relationship with Citrullus Species as Determined by High-frequency Oligonucleotides-targeting Active Gene Markers SO JOURNAL OF THE AMERICAN SOCIETY FOR HORTICULTURAL SCIENCE LA English DT Article ID MULTILOCUS GENOTYPE DATA; CULTIVATED WATERMELON; SELECTIVE SWEEPS; LANATUS; RESISTANCE; GENOME; ACCESSIONS; EVOLUTION; GERMPLASM; INFERENCE AB Citrullus colocynthis (CC) is a viable source of genes for enhancing disease and pest resistance in common cultivated watermelon [Citrullus lanatus var. lanatus (CLL)] cultivars. However, there is little information about genetic diversity within CC or the relationship of CC accessions to C. lanatus. In this study, we examined genetic diversity and relationships among 29 CC accessions collected in northern Africa, the Middle East, and Asia, and their relationships to 3 accessions and 3 cultivars of CLL, 12 accessions of citron melon [C. lanatus ssp. lanatus var. citroides (CLC)], and 1 accession representing the desert perennial Citrullus ecirrhosus (CE). Twenty-three high-frequency oligonucleotides-targeting active gene (HFO-TAG) primers were used to produce a total of 431 polymorphic fragments that target coding regions of the genome. Cluster and multidimensional scaling plot analysis, separated the CC into five groups, in general agreement with their geographic origins. CC genotypes admixed with CLL and CLC also were identified. Major reproductive barriers resulted in significantly reduced fertility in CC x CLL hybridizations. However, several of the U. S. PIs of CC were successfully crossed with watermelon cultivars using traditional breeding procedures, and the seeds produced from these crosses were viable. This suggests that CC can be a viable source to introduce biotic and abiotic stress resistance genes into cultivated watermelon.

The insect, which originated from Europe, utilizes species of Lactuca (lettuce) (Asteraceae) as a larval host. It was previously reported from northern Oregon and southern Washington but not the state of Idaho. The moth was subsequently captured in traps in six Idaho counties ranging from the south of the state near Utah to the north of the state in the panhandle area. A larva was also found on wild lettuce, Lactuca serriola L., near Boise, Idaho, and adults were captured in a light-trap near the southern border of the state. We conclude that the moth is generally distributed in the state at lower elevations where L. serriola is present.

The genomes of many plants have been sequenced, offering an opportunity to annotate and mine the retrocopies in plant genomes. However, comprehensive and unified annotation of retrocopies in these plants is still lacking. In this study I constructed the PlantRGDB (Plant Retrocopied Gene DataBase), the first database of plant retrocopies, to provide a putatively complete centralized list of retrocopies in plant genomes. The database is freely accessible at http://probes.pw.usda.gov/plantrgdbor http://aegilops.wheat.ucdavis.edu/plantrgdb. It currently integrates 49 plant species and 38,997 retrocopies along with characterization information. PlantRGDB provides a user-friendly web interface for searching, browsing and downloading the retrocopies in the database. PlantRGDB also offers graphical viewer-integrated sequence information for displaying the structure of each retrocopy. The attributes of the retrocopies of each species are reported using a browse function. In addition, useful tools, such as an advanced search and BLAST, are available to search the database more conveniently. In conclusion, the database will provide a web platform for obtaining valuable insight into the generation of retrocopies and will supplement research on gene duplication and genome evolution in plants.

TI Autoignition of wood under combined convective and radiative heating SO PROCEEDINGS OF THE COMBUSTION INSTITUTE LA English DT Article DE Ignition; Wood; Convection; Wildland fire ID FIRE SPREAD; IGNITION; MODEL; BEDS AB Many wildland fire models assume radiation heat transfer controls fuel particle ignition. However, evidence suggests that radiation is insufficient to ignite the predominantly small, thin fuel particles in wildlands and that convective heating by flame contact is a critical component. Here, convective ignition was studied using an apparatus containing two 6.5 kW electrical heaters to heat air from 600 degrees C to 800 degrees C. Steel screens straightened the flow and provided background radiant heat. This apparatus produced autoignition of dry red oak cylinders and disks. Cylinder diameter was varied from 0.64 to 1.91 cm and length from 2.5 to 7.5 cm. Disk diameters varied from 2.54 to 5.08 cm and 1 to 4 mm thick. The airflow rate varied slightly from 1.55 to 1.71 m/s due to the density difference. A simplified analytical model was developed that predicted the measured times reasonably well for air temperatures of 700 degrees C and above. (C) 2016 by The Combustion Institute.

Simeoni, Albert TI Investigation of firebrand production during prescribed fires conducted in a pine forest SO PROCEEDINGS OF THE COMBUSTION INSTITUTE LA English DT Article DE Surface fire; Firebrands; Generation; Characteristics AB This paper represents a study on the characterization of firebrand production which was carried out, using experimental fires conducted as prescribed fires in the New Jersey Pine Barrens, USA in March of 2013-2015. Several preliminary techniques were tested to characterize the firebrand production. Firebrands were collected from three plots for each year and analyzed for mass and size distribution. Thermal imagery was used to measure the velocity, size and number of firebrands in 2014 and 2015. The distribution of firebrands was evaluated in a monitored volume during the experiment. It was found that not less than 70% of collected particles were bark fragments and the rest were pine and shrub branches. The number of firebrands decreases with increasing the cross section area of firebrands. The mass of the particles varied from 5 to 50 mg, and the maximum number of the particles was observed for the mass range of 10-20 mg. About 80% of firebrands were particles with the cross section area of (5-20) x 10(-5) m(2). These results are consistent with the available observations of real fires [1,2]. Processing of infrared video showed that starting from a distance of 13 m from fire front, an increasing number of firebrands were observed in a controlled volume, increasing in number up to 180 per second. Relationships describing the time-variation of the number of particles that dropped on a 1.4 m(2) surface and the number of particles that flew through a 1 m(3) volume were obtained. Comparing the experimental and calculated data, we can conclude that these relationships allow us to describe the two numbers with an acceptable accuracy (adj. R-2 0.74 and 0.86, respectively).

TI Restoring big sagebrush after controlling encroaching western juniper with fire: aspect and subspecies effects SO RESTORATION ECOLOGY LA English DT Article DE Artemisia tridentata; burning; conifer control; Juniperus; recovery; seeding ID SAGE-GROUSE; ARTEMISIA-TRIDENTATA; SOUTHEASTERN OREGON; PLANT-COMMUNITIES; POSTFIRE RECOVERY; STEPPE; RESTORATION; PATTERNS; CONSERVATION; POPULATIONS AB The need for restoration of shrubs is increasingly recognized around the world. In the western United States, restoration of mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana [Rydb.] Beetle) after controlling encroaching conifers is a priority to improve sagebrush-associated wildlife habitat. Conifers can be cost effectively removed with prescribed burning when sagebrush is codominant; however, burning removes sagebrush and natural recovery may be slow. We evaluated seeding mountain and Wyoming big sagebrush (A. tridentata Nutt. ssp. wyomingensis Beetle & Young) on north and south aspects after western juniper (Juniperus occidentalis ssp. occidentalis Hook) control with prescribed burning. We included seeding Wyoming big sagebrush, a more drought tolerant subspecies of big sagebrush, because it might grow better than mountain big sagebrush on hot, dry south slopes, during drought, or after juniper encroachment. Seeding mountain big sagebrush increased sagebrush cover and density compared to unseeded controls. In mountain big sagebrush-seeded plots, sagebrush cover was 19 times greater on north compared to south aspects in the fourth year after seeding. At this time, sagebrush cover was also greater on mountain compared to Wyoming big sagebrush-seeded plots. Natural recovery (i.e. unseeded) of sagebrush was occurring on north aspects with sagebrush cover averaging 3% 4 years after fire. Sagebrush was not detected on unseeded south aspects at the end of the study. These results suggest that postfire sagebrush recovery, with and without seeding, will be variable across the landscape based on topography. This study suggests seeding sagebrush after controlling junipers with burning may accelerate sagebrush recovery.

These species continue to be used in some areas, especially after wildfires occurring in low elevation/precipitation, formerly Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis)/herbaceous communities. Seeding native species in these sites is often unsuccessful, and lack of establishment results in invasion and site dominance by exotic annuals. However, crested wheatgrass often forms dense monocultures that interfere competitively with the establishment of desirable native vegetation and do not provide the plant structure and habitat diversity for wildlife species equivalent to native-dominated sagebrush plant communities. During a 5-year study, we conducted trials to evaluate chemical and mechanical methods for reducing crested wheatgrass and the effectiveness of seeding native species into these sites after crested wheatgrass suppression. We determined that discing treatments were ineffective in reducing crested wheatgrass cover and even increased crested wheatgrass density in some cases. Glyphosate treatments initially reduced crested wheatgrass cover, but weeds increased in many treated plots and seeded species diminished over time as crested wheatgrass recovered. We concluded that, although increases in native species could possibly be obtained by repeating crested wheatgrass control treatments, reducing crested wheatgrass opens a window for invasion by exotic weed species.

However, one drawback of these restoration treatments is that slash is often burned in piles that may damage the soil and require further restoration activities. Pile burning is currently used on many forest sites as the preferred method for residue disposal because piles can be burned at various times of the year and are usually more controlled than broadcast burns. In many cases, fire can be beneficial to site conditions and soil properties, but slash piles, with a large concentration of wood, needles, forest floor, and sometimes mineral soil, can cause long-term damage. We describe several alternative methods for reducing nonmerchantable forest residues that will help remove excess woody biomass, minimize detrimental soil impacts, and create charcoal for improving soil organic matter and carbon sequestration.

Here we evaluate the potential of forest residue-based materials to rehabilitate burned soils. We compare soil nutrient and water availability, and plant recovery after application of 37 t ha(-1) of wood mulch, 20 t ha(-1) of biochar, and the combination of the two amendments with untreated, burned soils. We also conducted a greenhouse trial to examine how biochar influenced soil nutrient and water content under two wetting regimes. The effects of wood mulch on plant-available soil N and water content were significant and seasonally consistent during the three-year field study. Biochar applied alone had few effects under field conditions, but significantly increased soil pH, Ca, P, and water in the greenhouse. The mulched biochar treatment had the greatest effects on soil N and water availability and increased cover of the most abundant native plant. We found that rehabilitation treatments consisting of forest residue-based products have potential to enhance soil N and water dynamics and plant recovery following severe wildfire and may be justified where erosion risk or water supply protection are crucial.

TI A New Species of Cotton from Wake Atoll, Gossypium stephensii (Malvaceae) SO SYSTEMATIC BOTANY LA English DT Article DE Chloroplast DNA; Pacific Ocean; phylogeny; targeted sequence capture; taxonomy ID GENOME SEQUENCE; EVOLUTION; READS AB Wake Atoll is an isolated chain of three islets located in the Western Pacific. Included in its endemic flora is a representative of the genus Gossypium colloquially referred to as Wake Island cotton. Stanley G. Stephens pointed out that "Wake Island cotton does not resemble closely either the Caribbean or other Pacific forms." Taking into consideration morphological distinctions, the geographic isolation of Wake Atoll, and newly generated molecular data presented here, we conclude that the cottons of Wake Atoll do in fact represent a new species of Gossypium, here named Gossypium stephensii. This name is chosen to commemorate the eminent natural historian, evolutionary geneticist, and cotton biologist, S. G. Stephens.

TI EVALUATION OF SPRAY DRIFT FROM BACKPACK AND UTV SPRAYING SO TRANSACTIONS OF THE ASABE LA English DT Article DE Backpack sprayer; Pesticide deposition; Pesticide drift; Pesticide spray drift; UTV sprayer ID DEPOSITION AB The objective of these tests was to evaluate pesticide drift from ground applications using a standard manual pump backpack sprayer and a UTV-mounted boomless sprayer. Three deposition sampler types were deployed: Mylar cards, water-sensitive papers, and artificial foliage. This study indicates that drift of pesticide at 20 m downwind of backpack or UTV spraying was about 0.001 of the applied rate. This order of magnitude of drift was similar for both application methods. In the case of the backpack spraying, deposition decreased to about 0.01 of the applied rate just 1.5 m downwind of the swath edge. In the UTV trials, the closest off-swath measurement was 0.5 m downwind of the downwind swath edge, and deposition there ranged from about 0.5 of the applied rate down to less than 0.001. At 2.5 m downwind of the downwind swath edge, these values ranged from about 0.02 down to near 0.0001 of the applied rate. The study concludes that very small amounts of material were deposited at 20 m downwind, but drifted material was present. This conclusion is reached understanding that these trials were conservative by design, as there was almost no intervening vegetation between the release line and the collectors. The study also confirms the dependence of drift on wind speed in these applications. C1 [Thistle, H. W.; Kees, G. J.] USDA Forest Serv, 180 Canfield St, Morgantown, WV USA. [Bonds, J. A.

TI RUNOFF WATER QUALITY CHARACTERISTICS FOLLOWING SWINE SLURRY APPLICATION UNDER BROADCAST AND INJECTED CONDITIONS SO TRANSACTIONS OF THE ASABE LA English DT Article DE Land application; Manure management; Manure runoff; Nitrogen; Nutrients; Phosphorus; Runoff; Soil loss; Swine manure; Water quality ID NUTRIENT TRANSPORT; RAINFALL SIMULATOR; PHOSPHORUS LOSS; PLOT-SCALE; MANURE; SOIL; FERTILIZER; NITROGEN; REMOVAL; EROSION AB This study was conducted to measure the effects of swine slurry application method, time following slurry application, and runoff rate on selected water quality characteristics. Slurry from a commercial swine operation was broadcast or injected on field plots at a rate required to meet annual nitrogen requirements for corn. Rainfall simulation tests were conducted at five varying periods following slurry application. During each study period, three simulated rainfall events, separated by 24 h intervals, were applied for 30 min duration at an intensity of approximately 70 mm h(-1). Following the third rainfall simulation event, inflow was applied at the top of the plots in four successive increments to simulate greater plot lengths. Runoff samples were collected for analyses of dissolved P (DP), particulate P, total P (TP), NO3-N, NH4-N, total N, electrical conductivity, pH, and soil loss. The DP and TP loads of 0.35 and 0.46 kg ha(-1) measured for the broadcast treatment were significantly greater than the 0.13 and 0.19 kg ha(-1) obtained for the injection treatment. As time following slurry application increased from 1 to 3 days to 43 to 45 days, DP, TP, and NH4-N loads decreased from 0.35 to 0.14, from 0.52 to 0.18, and from 2.17 to 0.14 kg ha(-1), respectively. Runoff rate significantly affected each of the measured water quality parameters. Runoff loads of DP, TP, and NH4-N increased from 10.1 to 29.8, from 12.9 to 35.5, and from 13.9 to 25.1 g ha(-1) min(-1), respectively, as overland flow rate increased from 2.3 to 12.6 L min(-1). Application method, time following slurry application, and runoff rate are important variables influencing water quality characteristics of runoff. C1 [Schuster, N.

In this study, a new parameterization approach for estimating erodibility was developed for the Rangeland Hydrology and Erosion Model (RHEM). The approach uses empirical equations that were developed by applying piecewise regression analysis to predict the differences of erodibility before and after disturbance (i.e., wildfire, prescribed fire, and tree encroachment) and across a wide range of soil textures as a function of vegetation cover and surface slope angle. The approach combines rain splash, sheet flow, and concentrated flow erodibilities into a single parameter for modeling erodibility in most cases. We evaluated the new approach for sites representing different degrees of disturbance associated with burning and tree encroachment. Our results show that the new erodibility approach in RHEM predicts erosion at the plot scale with a satisfactory range of error in all cases. The new approach extends the applications of RHEM to a greater scope of landscapes and soil texture. C1 [Al-Hamdan, O. Z.] Texas A&M Univ, Dept Civil & Architectural Engn, Kingsville, TX USA.

TI EVALUATING THE APEX MODEL FOR SIMULATING STREAMFLOW AND WATER QUALITY ON TEN AGRICULTURAL WATERSHEDS IN THE US SO TRANSACTIONS OF THE ASABE LA English DT Article DE APEX; Calibration; Crop production; Hydrologic simulation; Validation; Water quality modeling ID CALIBRATION; PRODUCTIVITY; LANDSCAPES; EROSION; RUNOFF; TOOL AB To better understand the Agricultural Policy Environmental Extender (APEX) model's strengths and limitations in simulating streamflow and water quality, we evaluated its performance under a diverse range of climatic, topographic, soil, cover, and land management conditions using three parameter settings: best professional judgment (BPJ), partially calibrated, and fully calibrated. A total of 18 calibration parameters governing streamflow, crop yield, and sediment, N, and P were adjusted. Hydrologic and water quality responses were simulated on ten USDA-ARS watersheds with heterogeneous forested, pasture/range, and/or corn-soybean cropping systems. Based on percent bias and Nash-Sutcliffe coefficient of efficiency test statistics, 0%, 0%, 15%, and 9% of the data sets were considered satisfactory or better in simulating monthly streamflow, sediment, N, and P, respectively, in the BPJ mode. However, when used with the fully calibrated settings, 73%, 43%, 38%, and 27% of the data sets were satisfactory or better. Findings indicate that when fully calibrated, APEX estimates streamflow very well, sediment and nitrogen moderately well, and phosphorus marginally well at a monthly time scale. However, when using the BPJ approach, APEX does not estimate watershed-level streamflow, sediment, or nutrients accurately at a monthly time step. Additionally, APEX lacks an element of robustness in simulating streamflow and water quality constituents when applied to the same watershed with a different period of record or to a nearby watershed with a similar period of record. Based on these findings, it is recommended that users exercise caution when employing APEX with the BPJ approach or in validation mode at watershed scales. C1 [Van Liew, M.

The USDA-NRCS requested assistance in evaluating nomograph estimates of K for two soils that exhibit very different erodibilities based on field observations and expert opinion. In this study, we used a combination of laboratory measurements and process-based WEPP model simulations to estimate USLE K factors for four soils: a Miami silt loam from Indiana, an Opal clay from South Dakota, a Vergennes silty clay loam from Vermont, and a Mexico silty clay loam from Missouri. Experiments to estimate WEPP erosion parameters included: (1) simulated rainfall experiments to estimate WEPP model interrill erodibility (K-i) and (2) V-shaped mini-flume experiments to estimate WEPP model rill erodibility (K-r) and critical shear stress (tau(cr)). These estimates were made under three soil moisture conditions: initially dry, pre-wetted and then drained, and pre-wetted and saturated. Results showed that for the reference Indiana and Missouri soils, the back-calculated USLE K values from the dry and saturated soils were not significantly different from either the nomograph or RUSLE2 database values. For the South Dakota and Vermont NRCS test soils, the nomograph K was significantly lower than the experimentally derived K for initially dry and saturated soils and was also below the RUSLE2 database value. Saturated/drained soil moisture conditions resulted in the lowest back-calculated USLE K values for all soils. The process-based WEPP model with laboratory measurements of K-i, K-r, and tau(cr) allowed computation of USLE K and provided more conservative estimates of K for the South Dakota clay and Vermont silty clay loam soils. More science-based K values have soil conservation policy implications in that the RUSLE2 database may provide better estimates for K values than use of the nomograph for some soils.

New swine HMP data revealed considerable differences from previously reported data. This project determined new design VRs and evaluated differences from previously recommended VRs. The swine production stages evaluated included gestation, farrowing, nursery, growing, and finishing. The ranges of ambient temperature and ambient relative humidity (RH) evaluated for VR were -25 degrees C to 15 degrees C in 10 degrees C increments and 15% to 75% in 15% increments, respectively. Indoor set points for temperature and RH were, respectively, 15 degrees C, 20 degrees C, 25 degrees C and 60%, 70%, 80% for all five ambient stages. The results showed that the old VR for moisture control was 54%, 30%, 69%, 31%, and 53% lower than the new VR for the gestation, farrowing, nursery, growing, and finishing stages, respectively. Updated recommendations for ventilation are necessary for designing and managing modern swine facilities. C1 [Lu, Y.] Univ Illinois, Dept Agr & Biol Engn, Urbana, IL USA.

TI OPTIMIZATION AND MODELING OF FLOW CHARACTERISTICS OF LOW-OIL DDGS USING REGRESSION TECHNIQUES SO TRANSACTIONS OF THE ASABE LA English DT Article DE Dynamic flow properties; Flowabilty; Low-oil DDGS; Multivariate modeling ID DISTILLERS DRIED GRAINS; STORAGE; FLOWABILITY; POWDERS AB Storage conditions, such as temperature, relative humidity (RH), consolidation pressure (CP), and time, affect the flow behavior of bulk solids such as distillers dried grains with solubles (DDGS), which is widely used as animal feed by the U.S. cattle and swine industries. The typical dry-grind DDGS production process in most corn ethanol plants has been adapted to facilitate oil extraction from DDGS for increased profits, resulting in production of low-oil DDGS. Many studies have shown that caking, and thus flow, of regular DDGS is an issue during handling and transportation. This study measured the dynamic flow properties of low-oil DDGS. Flow properties such as stability index (SI), basic flow energy (BFE), flow rate index (FRI), cohesion, Jenike flow index, and wall friction angle were measured at varying temperature (20 degrees C, 40 degrees C, 60 degrees C), RH (40%, 60%, 80%), moisture content (MC; 8%, 10%, 12% w.b.), CP (generated by 0, 10, and 20 kg overbearing loads), and consolidation time (CT; 2, 4, 6, 8 days) for low-oil DDGS. Response surface modeling (RSM) and multivariate analysis showed that MC, temperature, and RH were the most influential variables on flow properties. The dynamic flow properties as influenced by environmental conditions were modeled using the RSM technique. Partial least squares regression yielded models with R-2 values greater than 0.80 for SI, BFE, and cohesion as a function of MC, temperature, RH, CP, and CT using two principal components. These results provide critical information for quantifying and predicting the flow behavior of low-oil DDGS during commercial handling and transportation.

Field data on urban trees were combined with local urban/community tree and land cover maps, modeling of tree effects on building energy use and pollutant emissions, and state energy and pollutant costs to estimate tree effects on building energy use and associated pollutant emissions at the state to national level in the conterminous United States. Results reveal that trees and forests in urban/community areas in the conterminous United States annually reduce electricity use by 38.8 million MWh ($4.7 billion), heating use by 246 million MMBtus ($3.1 billion) and avoid thousands of tonnes of emissions of several pollutants valued at $3.9 billion per year. Average reduction in national residential energy use due to trees is 7.2 percent. Specific designs to reduce energy use using urban trees could increase these values and further reduce energy use and improve air quality in the United States. Published by Elsevier GmbH.

Drift applications were made at the sixth leaf and first square growth stages using variable and constant carrier volumes and the same herbicide rate. Drift applied using variable carrier volumes were proportionally reduced with the herbicide rate while drift applied at constant carrier volumes were all made at 140 L ha(-1), regardless of herbicide rate. At 21 DAT, dicamba applied at variable carrier volumes reduced cotton heights 8% [from nontreated check (NTC)] compared to no change in height with dicamba applied at constant carrier volumes. The same effect was seen with 2,4-D applied at first square where variable carrier volumes decreased cotton heights 18% (from NTC) compared to 2% at 140 L ha(-1). Cotton yields were reduced to 70% of NTC when dicamba was applied at sixth leaf at variable carrier volumes compared to 87% at constant carrier volumes. The same response was seen with 2,4-D applied at sixth leaf where variable carrier volumes reduced cotton yields to 19% of NTC compared to 32% at constant carrier volumes. Cotton injury, height, boll production, and yield were all affected by drift carrier volume. When simulating herbicide drift in the future, it is critical to use variable carrier volumes for application as constant carrier volumes have shown to decrease the amount of plant injury observed.

TI Differential organization of taxonomic and functional diversity in an urban woody plant metacommunity SO APPLIED VEGETATION SCIENCE LA English DT Article DE Functional traits; Metacommunity; Urban ecosystem; Woody plants; alpha-Diversity; beta-Diversity ID SOCIOECONOMIC-STATUS; BIOTIC HOMOGENIZATION; BETA DIVERSITY; HABITAT TYPES; BIODIVERSITY; TRAITS; GARDENS; FRAMEWORK; URBANIZATION; CONTEXT AB Questions: Urban ecosystems present an opportunity to study ecological communities in the context of unprecedented environmental change. In the face of urban land conversion, ecologists observe new patterns of species composition, dominance, behaviour and dispersal. We propose a hypothetical socioeconomic template that describes a gradient in human investment in community composition to aid in organizing the human role in shaping urban biodiversity. We asked: (1) what is the relative magnitude of taxonomic and functional turnover of urban woody plant communities across different land-use types; and (2) do land uses exhibiting higher intensity of human management of biodiversity support higher turnover over those with less human influence? Location: Baltimore, MD, USA (39 degrees 17' N, 76 degrees 38' W). Methods: We examined patterns in woody plant biodiversity across 209 plots of different urban land uses. Six land-use types were arranged along a gradient in the intensity through which humans are hypothesized to manage species composition at the plot scale. We calculated local, or alpha-diversity, and compositional turnover, or beta-diversity, of taxonomic and functional diversity across plots within each land-use type. We compared the magnitude of these biodiversity measures between land uses to test our conceptual template for how the intensity of human management can predict urban woody plant biodiversity. Results: We observed high taxonomic turnover in residential and commercial plots compared with vacant or open space land-use areas. This was associated with a weaker, but similar, pattern in functional diversity. This was associated with low total abundance in residential and commercial plots. Furthermore, the number of unique species was extremely high in the same land-use types. Conclusions: Our observations help explain why turnover can be high in heavily managed plots relative to vacant land. In patches without heavy human management, we found low levels of turnover. This highlights the importance of assessing diversity both locally and at the level of turnover between patches. Management and policy can benefit from the perspective embodied in the conceptual approach tested here.

Can similar methods be used to create detailed predicted abundance maps for forage species? These predictions would be of great value for agricultural management and land-use planning. Location: Northeastern USA. Methods: We used field data from 31 grazed farms to model abundances for six forage species with three statistical Methods: GLM, GAM and Random Forest models. A hierarchical ecological framework encompassing climatic, edaphic and topographic variables related to the plant species requirements for water, light and temperature was used to guide variable selection. Results: Although many species distribution modelling studies have used only climatic variables, the inclusion of topography greatly improved explanatory power. Edaphic variables contributed little more beyond the information already provided by climate and topography. Random Forest models had higher overall predictive capability, and were used to produce the final potential abundance maps for the six forage species. Conclusions: Climate-only predictions may be suitable for state or regional planning, but topographic variables must be included in species distribution models used to support decision-making at the farm and field scales.

With the closure of regionally important oriented strand board and pulpwood operations, small-diameter logs are considered to have no value in some markets. This study was conducted to assess the volume and value of lumber produced from small-diameter hardwood logs of three important commercial species: red oak, sugar maple, and black cherry. Value assessments included determining yields for both green and kiln-dried lumber subjected to different dry kiln schedules. Volume and grade recovery from these small-diameter logs were lower than prior studies suggested. The value of recovered lumber per ft(3) of log volume was not found to be affected by log small-end diameter class for black cherry and red oak, but the value was significantly affected for sugar maple. The loss in lumber value that was attributed to kiln-dried based grade changes was greatest for red oak and least for sugar maple. For red oak, the modified dry kiln schedule did not affect the lumber value. For black cherry and sugar maple, there were kiln-schedule based differences in the value of the dry lumber recovered.

A web-based modeling system, the Kansas Biomass Supply Assessment Tool, was developed to identify least-cost sourcing areas for logging residues and upland hardwood roundwood biomass feedstocks. Geospatial boundaries were used according to the 5-digit zip code tabulation area ( ZCTA). This higher level of resolution advanced the understanding of the geospatial economics of modeling the supply chain for cellulosic feedstocks. The analyses were conducted for six sub-regions ( Chanute, Effingham, El Dorado, Manhattan, Ottawa, and Pratt) within Kansas that were identified by the US Forest Service as suitable for forest habitat. Atchison County of Effingham region had the least marginal costs for upland hardwood roundwood, ranging from $ 92.59 to $108.68 per dry metric ton, with an available annual supply of approximately 72 thousand dry metric tons. The least favorable was the El Dorado region, where the marginal costs ranged from $97.32 to $108.05 per dry metric ton, with an annual supply of approximately 4.4 thousand dry metric tons.

To develop an alternative method of rapid assessment of fungal decay in the laboratory, changes in static MOE of untreated and preservative-treated wood were measured during exposure to the brown-rot fungus, Gloeophyllum trabeum, and the white-rot fungus, Trametes versicolor, in a standard soil bottle assay. Static MOE loss was compared with mass loss. The results showed that the MOE of wood was a sensitive and reliable indicator of rot-fungal attack, regardless of fungus or wood species. The MOE analysis of untreated wood reduced the 12- to 16-week exposure time necessary for the standard mass loss measurement to four weeks. Also, the exposure time for preservative-treated wood was reduced to eight weeks. Untreated wood was determined to be susceptible to decay if the MOE loss was 40% or more after a four-week exposure, while treated wood was considered susceptible to decay if the MOE loss was 40% or more after an eight-week exposure.

Conversion yield and energy consumption were evaluated to profile the microwave-assisted liquefaction process. Chemical components of the bio-oils from various liquefaction conditions were identified. A higher reaction temperature was found to be beneficial to obtain higher energy consumption efficiency as heated by microwaves. Fourier transform infrared spectroscopy of the bio-oils indicated that hydroxyl groups underwent oxidation with increasing liquefaction temperature and/or prolonged reaction time; methanol esterification of oxidation products was also observed during the liquefaction process. The GC-MS chromatograms indicated that the further decomposition of C5 and C6 sugars resulted in a remarkable reduction of hydroxyl group products and an apparent increase in levulinic ester; furan derivatives and succinic acid derivatives were increased as well. The chemical reactions in liquefaction for the production of bio-oils mainly included decomposition of hemicelluloses, cellulose, and lignin; the oxidation reactions of the hydroxyl groups and methanol esterification were also presented. Comprehensively, a high content of hydroxyl group products was obtained at a moderate liquefaction condition (140 degrees C/15 min), and a high yield of levulinic ester products was acquired in severe reaction conditions (180 degrees C/15 min), regardless of energy consumption efficiency.

The HLB-associated pathogen [Candidatus Liberibacter asiaticus (CLas)] and vector [asian citrus psyllid (ACP), Diaphorina citri] were abundant, and trees were naturally challenged for 6 years before metrics (leaf mottle, percent canopy mottle, overall health, canopy density, canopy width, canopy height, and trunk diameter) were collected in Oct. and Nov. 2015. The healthiest trees with low or no HLB symptoms were distant citrus relatives: Balsamocitrus dawei, Bergera koenigii, Casimiroa edulis, Clausena excavata, Murraya paniculata, and one accession of Severinia buxifolia. Within Citrus, most of the healthiest trees with densest canopies, little leaf loss, and greater growth were those with pedigrees that included Citrus medica (citron). These included progenies of Citrus hybrid ('Limon Real'), Citrus limetta, Citrus limettioides, Citrus limonia, C. medica, Citrus volkameriana, and some Citrus limon accessions. Trees in this category exhibited distinct leaf-mottle characteristic of HLB and substantial pathogen titers, but maintained dense canopies and exhibited good growth. Trees from seed-source accessions in the genus Citrus without citron in their background were generally among the least healthy overall with less dense canopies. The exceptions were progenies of two Citrus aurantium accessions, which were markedly healthier than progenies of other Citrus seed-source accessions not derived from citron. Linear regression analysis, between metrics collected and pedigree of seed parent, indicated that percentage of citron in the pedigree significantly correlated with measures of tolerance. Although no commercial Citrus genotypes yielded progenies with strong HLB resistance, in this field experiment several progenies maintained dense canopies and good growth, and may be useful for breeding HLB tolerant cultivars.

Being a cool-season crop, lettuce is particularly vulnerable to heat stress. To adapt to climate change, this study was conducted to evaluate the performance of leaf lettuce genotypes for heat tolerance by growing them in different locations within California that differ in temperatures during the growing season. Fifteen green leaf and 21 red leaf lettuce genotypes were selected to evaluate their performance under these environments. These genotypes were planted in March and May in Five Points (San Joaquin Valley) and El Centro (Imperial Valley) and in June 2012 in Salinas (Salinas Valley). The results suggest that lettuce planting can be extended from January to March beyond the normal growing seasons in San Joaquin and Imperial Valleys, where yield may be higher than in the Salinas Valley. The further delay in planting date from March to May in Five Points and El Centro resulted in reduction of yield and an increase in susceptibility to bolting and heat-related disorders such as tipburn and leaf desiccation in most genotypes. The susceptibility to these disorders depends on the genotype and the temperature during lettuce growth and maturation. However, heat-tolerant leaf lettuce genotypes adapted to these regions were identified. Results of this research should be useful for the development of heat-tolerant lettuce cultivars and for extending the growing season in warmer but lower land cost areas to reduce production costs.

SO HORTSCIENCE LA English DT Article ID DIPLOCARPON-ROSAE; GENETIC-ANALYSIS; TETRAPLOID ROSES; COMPONENTS; WOLF AB Black spot disease, caused by the fungus Diplocarpon rosae Wolf, is one of the most serious diseases of garden roses. Both complete (vertical) resistance conditioned by dominant Rdr genes and partial (horizontal) resistance conditioned by multiple genes have been described. The use of resistant rose cultivars would reduce the demand of agrochemical applications. The characterization of 16 genotypes for resistance to black spot using two laboratory assays, the detached leaf assay (DLA) and the whole plant inoculation (WPI) approach, indicated that these techniques were well correlated. Thus, either method could be used to assess the resistance of the plants to black spot. Fifteen diploid hybrid populations from 10 parents segregating for partial (horizontal) resistance to black spot derived from Rosa wichuraiana 'Basye's Thornless' (RW) were assessed for black spot resistance by quantifying the percentage of the leaf area with symptoms (LAS) and lesion length (LL) measured by the diameter of the largest lesion per leaf in DLAs. The narrow-sense heritability of partial resistance to black spot as measured by LAS and LL data of DLA was estimated to be from 0.28 to 0.43 when calculated with a genetic variance analysis and from 0.74 to 0.86 when generated from offspring-midparent regression. This suggests that the development of rose cultivars with high levels of stable partial resistance to black spot is a feasible approach for the rose industry.

K. Koch] pollen grain germination are poorly understood for both in vitro pollen viability tests and on receptive stigmatic surfaces of pistillate flowers. Potential regulating factors include flavonols, calcium (Ca), Ca-like alkali earth elements (AEEs), and rare earth elements (REEs). When various concentrations of certain naturally occurring simple flavonols (e.g., quercetin, kaempferol, myricetin, naringenin, and hesperetin) were tested in vitro by adding to standard pecan pollen germination medium, hesperetin, myricetin, and kaempferol functioned as a strong agonist at low concentration (0.12-2.0 mu M for hesperetin and kaempferol, and 0.25 mu M for myricetin), increasing pollen germination 2- to 3.9-fold over flavonol-free media. Hesperetin and myricetin were antagonistic at 16 mu M. Kaempferol was not antagonistic at any concentration up to and including 16 mu M. Naringenin was an antagonist at concentrations from 0.12 to 16 mu M; whereas, quercetin was an antagonist at 8-16 mu M, but tended to function as an agonist at low concentration (0.12-0.50 mu M). The equal molar replacement of Ca2+ in standard pecan pollen germination media by single REEs, resulted in certain REEs [e.g., yttrium (Y), gadolinium (Gd), and thulium (Tm)] partially replacing the obligate need for Ca2+; thus, functioning as agonists in absence of Ca. All non-Ca AEEs [beryllium (Be), magnesium (Mg), strontium (Sr), expect for barium (Ba)], also partially substituted for Ca2+ at equivalent molar concentrations, but none were as efficacious as Ca2+. Results are suggestive that a) pollen germination in in vitro test can be improved by incorporation of certain flavonols, and b) pollen germination on stigmatic surfaces of flowers in orchards might be influenced or regulated by flavonol composition and Ca-like metals in the liquid matrix of the wet (receptive) stigmatic surface.

Available chemical treatments are not completely effective and, due to the length of the beetle dispersal period and insecticide breakdown, repeated treatments can become costly in terms of application expense and nontarget impacts. Additional options are needed to reduce application frequency and to provide an acceptable level of crop protection. Four treatments were tested using ethanol-injected eastern redbud trees at research sites in Mississippi (MS) and Tennessee (TN) over 2 years (2014-15), with the number of new ambrosia beetle galleries compared over time on 1) nontreated control trees, 2) kaolin-treated trees, 3) bifenthrin-treated trees, and 4) kaolin + bifenthrin (k + b)-treated trees. Kaolin-treated trees rapidly lost their coating after rain events and, at 6 days after treatment (DAT) in TN, no differences were detected in the number of beetle galleries between kaolin and nontreated control trees. Kaolin + bifenthrin-treated trees appeared to retain treatment residue longer, but were not better-protected than bifenthrin-treated trees at any time. Further research is needed to determine whether an adjuvant, such as a surfactant, spreader, or sticker, may enhance the modest impact offered by kaolin in our test, or if a reduction in rates of bifenthrin may be allowable.

The experiments were run under controlled chamber systems with inoculated fruit, and in boxed fruit under commercial conditions. For the inoculation test, fruit artificially inoculated with either Escherichia coli or Penicillium digitatum, or naturally inoculated Xanthomonas citri ssp. citri (Xcc) (fruits with citrus canker lesions), were incubated in a chamber containing a dose equivalent to 0-60 mg.L-1 of pure ClO2 as an antimicrobial agent. After 24 hours, the microbial population on treated grapefruit was significantly reduced compared with that of control fruit: a dosage of 5 mg.L-1 completely inhibit the growth of E. coli and P. digitatum, but a dosage of 60 mg.L-1 was needed to completely kill Xcc. For the simulated commercial experiment, fruit were harvested in late Oct. 2015 passed through a commercial packing line, and packed in 29 L citrus boxes. ClO2 packets were attached to the top lids with the following five treatments: fast-release, slow-release, slow/fast-release combination (each containing 14.5 mg.L-1 of pure ClO2), double dose fast-release (containing 29 mg.L-1 of ClO2), and control. After 6 weeks of storage at 10 degrees C (to simulate storage and transportation) + 1 week of storage at 20 degrees C (to simulate retail marketing), the fruit quality was evaluated. The slow-release treatment at standard dose exhibited the best antimicrobial activity, reducing total aerobic bacterial count and yeast/mold count by 0.95 and 0.94 log colony-forming units (cfu)/g of fruit, respectively, and maintained the best visual, sensory, and overall quality. However, the higher dosage treatments resulted in phytotoxicity as evidenced by peel browning.

This disorder typically develops during storage, but preharvest lesion can also develop. 'Honeycrisp' is also chilling sensitive, and fruit is typically held at 10-20 degrees C after harvest for up to 7 days to reduce development of chilling injury (CI) during subsequent cold storage. This temperature conditioning period followed by a lower storage temperature (2-4 degrees C) reduces CI risk but can exacerbate bitter pit development. Bitter pit development can be impacted in other apple cultivars by the use of controlled atmosphere (CA) storage and/or 1-methylcyclopropene (1-MCP). Studies were conducted to evaluate efficacy of CA and/or 1-MCP tomanage 'Honeycrisp' bitter pit development. Apples from multiple lots, obtained at commercial harvest, were held at 10 degrees C for 7 days and then cooled to 3 degrees C. Half the fruit was exposed to 42 mu mol.L-1 1-MCP the day of receipt while held at 10 degrees C. Fruit were stored in air orCA (3 kPa O-2, 0.5 kPa CO2 for 2 days, then 1.5 kPa O-2, 0.5 kPa CO2) established after 1 day at 10 degrees C or after 7 days at 10 degrees C plus 2 days at 3 degrees C. Fruit treated with 1-MCP and/or stored in CA developed less bitter pit compared with untreated fruit stored in air, and bitter pit incidence was lowest for 1-MCP-treated fruit with CA established during conditioning. Development of diffuse flesh browning (DFB) and cavities, reported to occur during 'Honeycrisp' CA storage, was observed in some lots. Incidence of these disorders was not enhanced by establishing CA 2 days compared with 9 days after harvest. 1-MCP and CA slowed peel color change, loss of soluble solids content (SSC) and titratable acidity (TA), and reduced ethylene production and respiration rate. The results indicate potential for the postharvest management of bitter pit development in 'Honeycrisp' apple through use of 1-MCP and/or CA storage.

There has been a long-standing debate as to which tissue better reflects the nutrient status of vines. A comparison of leaf blade and petiole nutrient concentrations was carried out to investigate which tissue better relates to vine growth, yield, and must nutrient responses of 'Pinot noir' grapevines to varying levels of nitrogen (N), phosphorus (P), and potassium (K) supply using data from a pot-in-pot vineyard over 4 years. Leaf blades and petioles were collected at 50% bloom and 50% veraison in each year and N, P, and K concentrations were assessed as predictors of leaf area at veraison, pruning mass at dormancy, yield, and must nutrient concentrations at fruit maturity. Data from commercial 'Pinot noir' vineyards were also used to investigate the relationship between leaf blade and petiole N concentrations with must N levels. Results indicated that leaf blades were superior to petioles in predicting vine growth, yield, and must yeast assimilable nitrogen (YAN) responses across a wide range of vine N status at both sampling times. Leaf blade N was a better predictor than petiole N in predicting YAN using data sets from both the pot-in-pot vineyard and commercial vineyards. Relationships between leaf blade and petiole concentrations of P and K and vine response variables generally did not differ and both tissues appeared to be equally effective in predicting P and K effects on growth, yield, and must P or K levels. Although petiole P was slightly better than leaf blade P at bloom in predicting must P levels, and models including both leaf and petiole K simultaneously as predictors relied only on leaf K. For all three nutrients, sampling at bloom and veraison had a similar predictive strength for response variables. Based on these findings, we recommend using leaf blades as opposed to petioles for diagnosing the N, P, and K status of 'Pinot noir'. C1 [Schreiner, R.

The Multiple Sample Isolation System for Solids (MSISS) was a major advance in the tree-ring alpha-cellulose extraction methods, offering greater throughput and reduced labor input compared to traditional alternatives. However, the usability of the method for resinous conifer species may be limited by the need to remove extractives from some conifer species in a separate pretreatment step. Here we test the necessity of pretreatment for alpha-cellulose extraction in loblolly pine (Pinus taeda L.), and the efficiency of a modified acetone-based ambient-temperature step for the removal of extractives (i) in loblolly pine from five geographic locations representing its natural range in the southeastern USA, and (ii) on five other common coniferous species (black spruce (Picea mariana Mill.), Fraser fir (Abies fraseri (Pursh) Poir.), Douglas fir (Pseudotsuga menziesii (Mirb.) Franco), Norway spruce (Picea abies (L.) Karst) and ponderosa pine (Pinus ponderosa D.)) with contrasting extractive profiles. The differences of delta C-13 values between the new and traditional pretreatment methods were within the precision of the isotope ratio mass spectrometry method used (+/- 0.2%), and the differences between delta O-18 values were not statistically significant. Although some unanticipated results were observed in Fraser fir, the new ambient-temperature technique was deemed as effective as the more labor-consuming and toxic traditional pretreatment protocol. The proposed technique requires a separate acetone-inert multiport system similar to MSISS, and the execution of both pretreatment and main extraction steps allows for simultaneous treatment of up to several hundred microsamples from resinous softwood, while the need of additional labor input remains minimal.

Satellites (e.g., Soil Moisture Active Passive [SMAP] and Soil Moisture and Ocean Salinity [SMOS]) using passive microwave techniques, in particular at L-band frequency, have shown good promise for global mapping of near-surface (0-5-cm) soil moisture at a spatial resolution of 25 to 40 km and temporal resolution of 2 to 3 d. C- and X-band soil moisture records date back to 1978, making available an invaluable data set for long-term climate research. Near-surface soil moisture is further extended to the root zone (top 1 m) using process-based models and data assimilation schemes. Validation of remotely sensed soil moisture products has been ongoing using core monitoring sites, sparse monitoring networks, intensive field campaigns, as well as multi-satellite comparison studies. To transfer empirical observations across space and time scales and to develop improved retrieval algorithms at various resolutions, several efforts are underway to associate soil moisture variability dynamics with land surface attributes in various energy-and water-rich environments. We describe the most recent scientific and technological advances in soil moisture remote sensing. We anticipate that remotely sensed soil moisture will find many applications in vadose zone hydrology in the coming decades.

Keough, Heather TI Community-Level Impacts of Management and Disturbance in Western Michigan Oak Savannas SO AMERICAN MIDLAND NATURALIST LA English DT Article ID DUNES; SCALE; VEGETATION; DIVERSITY; ECOLOGY; INDIANA; SOIL; REGENERATION; COEXISTENCE; MODELS AB Midwestern oak savanna systems are typically defined by their open canopy and the co-existence of scattered mature oak trees and a ground layer dominated by herbaceous vegetation. The structure of these systems is thought to be primarily maintained by disturbance such as fire. In this study we examined the plant community of 21 different oak savanna sites in western Lower Michigan, U.S.A., across a coarse disturbance gradient created by different management practices. Herbaceous community composition differed significantly across a variety of management approaches, while overall diversity remained similar. Indicator species analysis (ISA) identified several species commonly associated with mixed oak forest understories (e.g., Maianthemum canadense) as indicators for recently abandoned oak savanna sites, whereas the indicators identified for managed or heavily disturbed sites included common savanna-associates (e.g., Lupinus perennis). Variation in soil characteristics (C:N ratio and pH) and canopy cover may be driving these differences in plant community composition between management approaches. These results reinforce the importance of disturbance to Midwestern oak savanna ecosystems. Furthermore, if long-term management goals include encouraging the establishment and maintenance of herbaceous oak savanna-associated plant species, disturbance created through management activities, such as hand cutting, will likely yield better results over inaction, especially where using fire is not an option.

TI Characteristics, Histories, and Future Succession of Northern Pinus pungens Stands SO AMERICAN MIDLAND NATURALIST LA English DT Article ID TABLE MOUNTAIN PINE; SOUTHERN APPALACHIAN MOUNTAINS; NORTHEASTERN UNITED-STATES; GREAT SMOKY MOUNTAINS; FIRE HISTORY; 3 CENTURIES; LAND-USE; USA; FORESTS; PENNSYLVANIA AB Pinus pungens (Table Mountain pine) stands are rare conifer-dominated communities that occur on xeric ridges and upper slopes throughout the central and southern Appalachian Mountains. At the northern end of this range, this uncommon forest community is essentially unstudied. Therefore, in 2006 I initiated a dendroecology study of three Pinus pungens stands growing in Pennsylvania to better understand their current conditions, histories, and likely future succession. These stands contained from four to 14 tree species with Pinus pungens or Quercus montana (chestnut oak) dominating the main canopy. Quercus coccinea (scarlet oak), Acer rubrum (red maple), or Nyssa sylvatica (black gum) were the primary species of the midstory. Kalmia latifolia (mountain laurel) was the principal understory shrub. Two of the communities had Pinus pungens and Quercus montana trees dating back into the mid-1800s and were likely heavily influenced by the charcoal iron industry of that century. Periodic fire was also part of their history. The other Pinus pungens community arose following abandonment of an agricultural field in the 1910s and fire does not seem to have been a factor in its ecological history. Two of the communities appear to be losing their Pinus pungens component as their understories are dominated by hardwood saplings or shrubs and there are no pine seedlings present. Perpetuating these and other Pinus pungens communities in Pennsylvania will require reducing the understory vegetation and creating suitable seed beds for Pinus pungens seedling establishment.

The field has evolved over the past six decades concerning methodology, data monitoring and field collection, and interdisciplinary linkages. Avalanche climate research directions are also expanding concerning treatment in both spatial scale and temporal timescales. This article provides an overview of the main themes of avalanche climate research in issues of scale from local to global, its expanding interdisciplinary nature, as well as its future challenges and directions. The growth of avalanche climatology includes themes such as its transformation from being mostly descriptive to innovative statistical methods and modeling techniques, new challenges in microscale efforts that include depth hoar aspects and increased field studies, expanding synoptic climatology applications on studying avalanche variations, efforts to reconstruct past avalanches and relate them to climatic change, and research on potential avalanche responses to recent twentieth-century and future global warming. Some suggestions on future avalanche climatology research directions include the expansion of data networks and studies that include lesser developed countries, stronger linkages of avalanche climate studies with GIScience and remote sensing applications, more innovative linkages of avalanches with climate and societal applications, and increased emphases on modeling and process-oriented approaches.

Plant-to-plant transmission by polyphagous leafhoppers determined that 'Ca. Phytoplasma solani' strains exist in diverse plant hosts in varied ecosystems, where selection conceivably influences intra-species strain diversity. In this study, virtual restriction fragment length polymorphism (RFLP) and single nucleotide polymorphism (SNP) analyses of 16S rDNA nucleotide sequences, amplified from grapevines and bindweeds in central-eastern Italy, revealed the presence of two new subgroups (16SrXII-J and 16SrXII-K) in the 16SrXII group, and of genetically distinct SNP lineages. Findings from the present and related works report the extensive intra-species diversity among 'Ca. Phytoplasma solani' strains in vineyards, underscoring the need for further studies to investigate relationships between diverse phytoplasma strains and dynamics of bois noir epidemiology.

Infected leaves showed rust-like symptoms on the abaxial and adaxial leaf surfaces. Uredinia appeared bright orange when fresh, releasing profuse, bright orange urediniospores, which distinguished it from Puccinia melanocephala, the only rust species known to infect sugarcane in southern Africa at that time. No identical matches were obtained from the NCBI database for the combined ITS and 28S nuclear large subunit (nLSU) regions for the unknown rust. Phylogenetic analyses based on the same gene region showed that this rust was closely related to Macruropyxis fraxini and Puccinia sparganioides, which infect Fraxinus spp. (Oleaceae). Also closely related were Aecidium klugkistianum, P. mysuruensis, and P. physalidis which infect host species in the Oleaceae, Rubiaceae, and Solanaceae, respectively. This group of rusts is phylogenetically distinct from both Puccinia melanocephala and Puccinia kuehnii, which cause brown and orange rust of sugarcane, respectively. Phylogenetic reconstruction showed that the unknown rust falls outside the Puccinia I and II clades and groups with the Macruropyxis clade with strong bootstrap support. Hence the name proposed for this newly discovered rust species is Macruropyxis fulva sp. nov., causal agent of tawny rust of sugarcane. A rust observed to be infecting Miscanthus ecklonii in 2016 matched the accessioned M. fulva sp. nov. sequences and was morphologically and genetically distinct from the Miscanthus rust Puccinia miscanthidii, providing evidence of an alternate host for M. fulva sp. nov.

The outbreak had a negative $3.3 billion impact on the economy. Seventeen trading partners suspended imports of all US-origin poultry and poultry products while 38 trading partners regionalized the United States, and allowed trade in poultry and poultry products to continue from areas of the US not affected by HPAI. Disease response and control activities in addition to the use of comprehensive surveillance and regionalization (zoning) as prescribed by the OIE Terrestrial Animal Health Code are a scientifically valid and effective means to maintain safe trade in poultry and poultry products. This was further realized during the 2016 H7N8 HPAI outbreak in Dubois County, Indiana, with greater acceptance of regionalization and continuity in trade with a more limited cost of $30 million for eradication.

In Spain, from the spring of 2011 to 2013, an increased number of outbreaks in broiler and broiler breeder flocks from different regions occurred. The objectives of the present work were to carry out the molecular characterization of FAdV strains from Spanish inclusion body hepatitis cases and to study the pathogenicity and viral dynamics of these strains in specific pathogen-free (SPF) chickens. A total of 52 inclusion body hepatitis clinical cases, including 45 from broiler farms and seven from broiler breeder farms, were analysed by conventional polymerase chain reaction and sequencing targeting the FAdV hexon gene. From these, 37 strains were classified as FAdV type 8b, while the remaining 15 were classified as FAdV types 11 (n=10), 2 (n=4) and 8a (n=1). In addition, two different FAdVs belonging to the genotypes 8b and 11 were used for experimental infection. Specific pathogen-free five-day-old birds were inoculated intramuscularly with a high (10(6.5) tissue culture infective dose (TCID)(50)/ml) or low (10(4) TCID50/ml) dose of the above-mentioned FAdVs. No mortality was observed in any of the experimental groups, and only one bird showed evident clinical signs. However, macroscopic and microscopic hepatic lesions, as well as viral DNA, were detected in birds from all infection groups. Inclusion bodies and viral DNA were also detected in the pancreas and in the small and the large intestine in some birds. Long-lasting shedding and transmission to contact birds were confirmed in all infected groups.

Under dry greenhouse conditions, ca. 58% mortality was observed among second-instar larvae exposed directly to sprays of B. bassiana conidia, whereas mortality among larvae exposed to similarly treated foliage (either leaf dorsal or ventral surfaces) was <10%. Mortality was ca. 64% among larvae exposed to both direct sprays and foliar spray deposits. Equivalent rates of mortality were observed among larvae treated with a clay-based wettable powder versus an emulsifiable oil-based formulation of B. bassiana conidia; however, this was observed despite application of an approximately 40% greater dose of WP-formulated conidia, indicating greater efficacy of the emulsifiable oil formulation. These results suggest that, under dry conditions, potato beetle larvae do not readily acquire an effective dose of conidia from treated foliage and that development of improved application technologies to more effectively target the larvae may ultimately prove more beneficial than development of formulations with greater foliar persistence.

In Ldlr(-/-) mice fed a high-fat diet (HFD), curcumin reduces plasma lipid levels, therefore contributing to a lower accumulation of lipids and to reduced expression of fatty acid transport proteins (CD36/FAT, FABP4/aP2) in peritoneal macrophages. In this study, we analyzed the molecular mechanisms by which curcumin (500, 1000, 1500 mg/kg diet, for 4 months) may influence plasma and tissue lipid levels in Ldlr(-/-) mice fed an HFD. In liver, HFD significantly suppressed cAMP levels, and curcumin restored almost normal levels. Similar trends were observed in adipose tissues, but not in brain, skeletal muscle, spleen, and kidney. Treatment with curcumin increased phosphorylation of CREB in liver, what may play a role in regulatory effects of curcumin in lipid homeostasis. In cell lines, curcumin increased the level of cAMP, activated the transcription factor CREB and the human CD36 promoter via a sequence containing a consensus CREB response element. Regulatory effects of HFD and Cur on gene expression were observed in liver, less in skeletal muscle and not in brain. Since the cAMP/protein kinase A (PKA)/CREB pathway plays an important role in lipid homeostasis, energy expenditure, and thermogenesis by increasing lipolysis and fatty acid -oxidation, an increase in cAMP levels induced by curcumin may contribute to its hypolipidemic and anti-atherosclerotic effects.

Panel Encompassing Broad Genetic Variability for Cooking Time SO CEREAL CHEMISTRY LA English DT Article ID DIETARY FIBER; WATER-ABSORPTION; RESISTANT STARCH; WHOLE GRAINS; CELL-WALL; POLYSACCHARIDES; LEGUMES; STORAGE; REGISTRATION; CHICKPEAS AB Dry beans are typically consumed as a whole food, and cooking time is one of the most important processing quality attributes. A panel of eight dry bean entries with variability in cooking time was established, grown in three locations, and used to test the hypothesis that carbohydrate components are major underlying contributors to genetic variability in cooking time. The cooking times ranged from 17 to 160 min. In general, faster cooking bean genotypes had higher levels of soluble dietary fiber in both the raw and cooked samples. Resistant starch levels in the raw beans, although not correlated with cooking time, were of interest because of the large genotypic variability, and they ranged from 1.5 to 3 5%. One genotype in particular, a yellow bean from Africa, Cebo Cela, had low resistant starch levels in the raw seeds of 1.5-2.5%, whereas average resistant starch levels in the entire panel were 26-30%. Resistant starch levels (3.9-4.2%) in the cooked seed of Cebo Cela were comparable to the other genotypes (3.4-4.3%). Based on light microscopy, the cell walls did not remain intact in the raw milled seed used for the analyses, but they did remain intact in the cooked samples, suggesting the differences in resistant starch in the raw seed are related to starch structure.

Soil samples were collected from two experimental fields managed according to organic farming regulations and a sequential fractionation procedure was applied to separate the light fraction (LF), particulate organic matter (POM), and mobile humic acid (MHA). Contents of carbohydrates and amino compounds were determined in soil and correspondent SOM fractions. Over a 2-year course, carbohydrate contents decreased in the LF fraction while it increased noticeably in the POM and slightly in the MHA fractions leading into questioning whether decomposing materials get incorporated into older fractions. Amino N content constituted up to 30% of total soil N, with a major contribution of the humic fraction (MHA). Although the LF, POM, and MHA fractions showed the greatest amino N content after the compost-legumes combinations, the carbohydrate and amino N contents in the POM and MHA fractions of the unamended soil increased as large as the corresponding fertilized plots, underlining that conservative soil management results in accumulation of labile forms of soil C and N that consequently might build up soil fertility. The changes after different treatments suggest the suitability of carbohydrates and amino compounds as short-term indicators for soil management.

A. marginale OMPs 7 to 9 are logical vaccine candidates because they are surface exposed, present in the OM immunogen and protective cross-linked OM proteins, recognized by immune serum IgG2 and T cells in cattle immunized with OM, and recognized by immune serum IgG2 from cattle immunized with the A. centrale vaccine strain. We report the identification of a globally conserved 9-amino-acid T-cell epitope FLLVDDAI/VV shared between A. centrale vaccine strain OMP7 and the related A. marginale OMPs 7 to 9, where position 8 of the peptide can be isoleucine or valine. The epitope is conserved in American A. marginale strains, in the Australia Gypsy Plains strain, and in multiple field isolates from Ghana. This epitope, together with additional T-cell epitopes that are present within these proteins, should be considered for inclusion in a multivalent vaccine for A. marginale that can provide protection against disease caused by globally distributed bacterial strains.

In an Idaho field study of winter wheat (Triticum aestivum L.) following organically fertilized sugarbeet (Beta vulgaris L.), we determined the residual (second-year) effects of fall-applied solid dairy manure, either stockpiled or composted, on wheat yield, biomass N, protein, and grain N removal. Along with a no-N control and urea (202kg N ha(-1)), first-year treatments included compost (218 and 435kg estimated available N ha(-1)) and manure (140 and 280kg available N ha(-1)). All materials were incorporated into a Greenleaf silt loam (Xeric Calciargid) at Parma in fall 2002 and 2003 prior to planting first-year sugarbeet. Second-year wheat grain yield was similar among urea and organic N sources that applied optimal amounts of plant-available N to the preceding year's sugarbeet, thus revealing no measurable second-year advantage for organic over conventional N sources. Both organic amendments applied at high rates to the preceding year's sugarbeet produced greater wheat yields (compost in 2004 and manure in 2005) than urea applied at optimal N rates. On average, second-year wheat biomass took up 49% of the inorganic N remaining in organically fertilized soil after sugarbeet harvest. Applying compost or manure at greater than optimum rates for sugarbeet may increase second-year wheat yield but increase N losses as well.Abbreviations CNS, carbon-nitrogen-sulfur C1 [Lehrsch, G.

TI Influence of Soil Properties and Manure Sources on Phosphorus in Runoff during Simulated Rainfall SO COMMUNICATIONS IN SOIL SCIENCE AND PLANT ANALYSIS LA English DT Article DE Phosphorus runoff; poultry manure; simulated rainfall ID POULTRY LITTER; LOSSES AB Runoff from agricultural fields amended with animal manure or fertilizer is a source of phosphorus (P) pollution to surface waters, which can have harmful effects such as eutrophication. The objectives of this study were to evaluate the impact of soil P status and the P composition of manure sources on P in runoff and characterize the effects of manure sources on mass loss of dissolved reactive P, total dissolved P, and total P in runoff. Soil boxes set at 5% slopes received 7.5cmh(-1) of simulated rainfall for 30min. Study soils included a Kenansville loamy sand (loamy siliceous subactive thermic Arenic Hapludults, a Coastal Plain soil) and a Davidson silt loam (kaolinitic thermic Rhodic Kandiudults, a Piedmont soil). Soil test P concentrations ranged from 16 to 283mg P kg(-1). Sources of P included broiler litter, breeder manure, and breeder manure treated with three rates of aluminum sulfate (Al-2(SO4)(3)) 0, 3.9, and 7.8kg m(-2), di-ammonium phosphate (DAP), and an un-amended control. All manure sources were surface applied at 66kg P ha(-1) without incorporation. Water extractable P represented an average of 10 +/- 6% total P in manure. Runoff samples were taken over a 30-min period. Piedmont soil contained greater amounts of clay, aluminum (Al), and iron (Fe) concentrations, and higher P sorption capacities that produced significantly lower dissolved reactive P, total dissolved P, and total P losses than the Coastal Plain soil. Runoff P loss did not differ significantly for low and high STP Coastal Plain soils. Water extractable P in manures accounted for all dissolved reactive P lost in runoff with dissolved reactive P correlating strongly with water extractable P concentration (r(2)=0.9961). Overall, manures containing the highest water extractable P concentrations contributed to the largest amounts of dissolved reactive P in runoff. Manure treated with 3.9 and 7.8kg m(-2) of Al-2(SO4)(3) (alum) decreased dissolved reactive P in runoff by 29%. While this soil box runoff study represents a worst-case scenario for P loss, highly significant effects of soil properties and manure sources were obtained. Management based on these results should help ameliorate harmful effects of P in runoff. C1 [Roberts, John] North Carolina State Univ, Dept Crop & Soil Sci, Raleigh, NC 27695 USA.

TI Succession of vegetation after a high-intensity fire in a pine forest with lichens SO CONTEMPORARY PROBLEMS OF ECOLOGY LA English DT Article DE forest fire; succession; pine stand; reforestation; fuel loads AB This paper presents the results of 20-year studies into the impact made by an experimental high-intensity fire on ecosystem components and postfire succession in a middle-taiga pine forest. About 44% of forest fuel loads burned down during the fire, and the emission of carbon was more than 18 t C/ha. As a result of the fire impact, trees died within 3 years after the fire, and this resulted in a significant accumulation of fuel loads. Twenty years after the fire, the biomass of forest fuel loads surpassed the prefire values 4 times, which led to the possibility of the origin of a repeated high-intensity fire. The initial stage of postfire succession in the pine forest is determined by forest vegetation conditions and takes place with the replacement of dominant grass and shrubs. The agrochemical and hydrothermal soil indicators were revealed to be changed after the fire, and this promoted improved conditions for the origin and development of natural regeneration sufficient for the formation of forest stand.

Landscape patterning in consumer population dynamics may be largely the result of interactions between consumers and their predators, or driven by spatial variation in basal resources. Empirical testing of these alternatives has been limited by the lack of suitable data. In this study, we analyzed an extensive network of spatially replicated time series to characterize the local and regional processes affecting spatio-temporal dynamics of a tree-killing bark beetle (Dendroctonus frontalis or SPB) and its key predator (Thanasimus dubius) across the southeastern United States. We first used a mechanistic model to evaluate factors affecting the stability of 95 predator-prey time series and then conducted spatial analyses to evaluate scale dependence in the factors affecting the geographical patterning of this system. Across the region, population fluctuations of both species were correlated in space beyond 400 km but there was notable spatial variation in the deterministic and stochastic processes influencing forest-scale (local) fluctuations. Time series analyses indicated that local dynamics of SPB and T. dubius are not cyclical. Instead, the abundance of T. dubius responded almost instantaneously to changes in SPB abundance. Spatial variation in long-term forest-scale abundance of both species was linked most strongly to the abundance of pine habitat indicating a stronger role for resource availability in SPB population dynamics than top-down effects. Our results are consistent with other studies indicating that animal populations tend to be synchronized in space via spatially correlated processes such as weather; yet local dynamics tend to be linked to smaller-scale host patterns. Our study provides a rare empirical assessment of how local processes scale up to produce landscape patterns that influence forest ecology and forest management.

(Coleoptera: Curculionidae), is a periodic pest of pea, Pisum sativum L. (Fabaceae), in the Palouse region of northern Idaho and eastern Washington, USA. Previous work on-station and in commercial pea fields showed initial adult weevil colonization was greater in conventional-tillage than in no-tillage fields. Increased surface residue of no-tillage systems results in cooler soils with greater available moisture typically resulting in later planting dates for conventional-tillage fields. Cereal residue, a characteristic of the region's no-tillage systems, and planting date were investigated as potential inhibitors of adult pea leaf weevil colonization and feeding on peas via field experiments in 2005 and 2006. Plots without cereal residue and early-planted plots had greater weevil abundance. Early-planted peas had greater weevil feeding injury compared to late-planted peas. The presence of cereal residue did not significantly impact injury levels. A laboratory choice-test with peas grown in conventional-tillage and no-tillage fields indicated greater adult weevil feeding damage on conventional-tillage-grown peas. A separate laboratory choice-test using peas planted 10 days apart demonstrated greater adult weevil feeding injury on early-planted peas. However, adjusting for available leaf edge resulted in no differences between treatments in either choice test, indicating crop availability and plant apparency during peak weevil colonization rather than plant factors resulting from growing conditions likely explain greater injury on peas planted early and under conventional-tillage in the field.

Thus, solid C-13 and solution P-31 nuclear magnetic resonance (NMR) spectroscopy were used to characterize biomass of six aquatic plants in Tai Lake, China. The results showed that carbohydrates (61.2% of the total C) were predominant C functional group in the solid C-13 NMR spectra of plant biomass, which may indicate high lability and bioavailability of aquatic plants-derived organic matter in lakes. There was 72.6-103.7% of the total P in aquatic plant biomass extracted by NaOH-EDTA extracts. Solution P-31 NMR analysis of these NaOH-EDTA extracts further identified several molecular species of P including orthophosphate (50.1%), orthophosphate monoesters (46.8%), DNA (1.6%) and pyrophosphate (1.4%). Orthophosphate monoesters included beta-glycerophosphate (17.7%), hydrolysis products of RNA (11.7%), alpha-glycerophosphate (9.2%) and other unknown monoesters (2.1%). Additionally, phytate, the major form of organic P in many lake sediments, was detected in floating plant water poppy. These inorganic P (e.g. orthophosphate and pyrophosphate) and organic P (e.g. diester and its degradation products) identified in plant biomass were all labile and bioavailable P, which would play an important role in recycling of P in lakes. These results increased knowledge of chemical composition and bioavailability of OMs derived from aquatic plants in lakes.

Plots were burned two to four times over an eight-year period with low intensity surface fires during one of four six-week long periods from early April to mid-September. Density of saplings (0.25-11.6 cm diameter at breast height) was significantly reduced after one or two fires during the first four-year period. Sapling density declined with additional burning over the next four years, but density of mesic hardwoods including sweetgum (Liquidambar styraciflua) and red maple (Acer rubrum) remained relatively high (similar to 865 stems ha(-1)). Repeated burning had little effect on density or basal area of trees (>= 11.7 cm dbh) and changes in overstory structure were limited to small increases in the quadratic mean diameter of all trees and pines. We found little evidence to suggest differential effects on structure or composition due to timing of burn within the growing season. Although repeated growing season burning alters midstory structure and composition, burning alone is unlikely to result in immediate shifts in overstory composition or structure in mixed pine-hardwood forests of the southeastern Piedmont region.

In this study, we combined two-dimensional time-lapse electrical resistivity imaging (ERI) (depth of investigation approximately 2m) with hydrometric monitoring to examine hydrological processes in the riparian area of FD-36, a small (0.4km(2)) agricultural headwater basin in the Valley and Ridge region of east-central Pennsylvania. We selected two contrasting study sites, including a seep with groundwater discharge and an adjacent area lacking such seepage. Both sites were underlain by a fragipan at 0.6m. We then monitored changes in electrical resistivity, shallow groundwater, and nitrate-N concentrations as a series of storms transitioned the landscape from dry to wet conditions. Time-lapse ERI revealed different resistivity patterns between seep and non-seep areas during the study period. Notably, the seep displayed strong resistivity reductions (similar to 60%) along a vertically aligned region of the soil profile, which coincided with strong upward hydraulic gradients recorded in a grid of nested piezometers (0.2- and 0.6-m depth). These patterns suggested a hydraulic connection between the seep and the nitrate-rich shallow groundwater system below the fragipan, which enabled groundwater and associated nitrate-N to discharge through the fragipan to the surface. In contrast, time-lapse ERI indicated no such connections in the non-seep area, with infiltrated rainwater presumably perched above the fragipan. Results highlight the value of pairing time-lapse ERI with hydrometric and water quality monitoring to illuminate possible groundwater and nutrient flow pathways to seeps in headwater riparian areas.

However, multiple versions of a model may be needed for different food safety applications, such as hazard analysis and critical control point (HACCP) programs and risk assessment. A neural network model for growth of Salmonella in ground chicken as a function of time (0 to 8 days) at 16 degrees C and serotype (n = 8) was developed. The proportion of residuals in an acceptable prediction zone (pAPZ) from -1 log (fail-safe) to 0.5 log (fail-dangerous) was 0.948 for training data (n = 192) and 0.988 for testing data (n = 84). A pAPZ >= 0.7 indicated that the model provided predictions with acceptable bias and accuracy. Thus, the model was successfully validated. Different versions of the model were developed for application in HACCP and risk assessment. C1 [Oscar, Thomas.

Empirical functions to predict bulk density as a function of height for 4-year-old chaparral were developed for two typical species of shrub fuels in southern California, USA, namely chamise (Adenostoma fasciculatum Hook & Arn.) and manzanita (Arctostaphylos spp. Adans.). Fuel beds of chamise foliage and small-diameter branches were burned in an open-topped wind tunnel. Three levels of bulk density, two ignition locations and two wind speeds were examined, focusing on overall fire behaviour. Mean maximum mass loss rate, elapsed time at which maximum mass loss rate occurred, flame height, flame angle, peak gas temperature and its peak change rate were measured. The mean maximum mass loss rate was not significantly affected by wind speed, ignition location, bulk density or moisture content. Both wind speed and ignition location significantly affected the time that maximum mass loss rate occurred. Only wind speed affected flame height and flame angle. The peak gas temperature within the shrub burning area was found to be mostly affected by the bulk density. C1 [Li, Jing] Univ New Haven, Dept Fire Sci & Profess Studies, West Haven, CT 06516 USA.

SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE communication; fire safety; research delivery ID RICHNESS; DESIGN; MEDIA AB Creating a safe workplace for wildland firefighters has long been at the centre of discussion for researchers and practitioners. The goal of wildland fire safety research has been to protect operational firefighters, yet its contributions often fall short of potential because much is getting lost in the translation of peer-reviewed results to potential and intended users. When information that could enhance safety is not adopted by individuals, the potential to improve safety-to decipher the wildland fire physical or social environment and to recognise hazards-is lost. We use firefighter safety-zone research as a case study to examine how primary research is, and could be, transferred to fire managers, policy-makers and firefighters. We apply four core communication theories (diffusion, translation, discourse and media richness) to improve knowledge transfer.

In the present study, three aqueous solutions of sodium hypochlorite (SH, 100 mg/L), chlorine dioxide (CD, 10 mg/L), and sodium butyl p-hydroxybenzoate (SBPH, 12 mg/L), and tap water, were used to treat fresh coriander for 15 min. The treated samples were packed in PVC boxes with ambient air under packaged under passive modified atmosphere packaging conditions and stored at 4 degrees C for 10 days. Effects of washing treatments on color, total chlorophyll contents, ascorbic acid contents, total contents of phenolic compounds, and total aerobic bacterial counts (APC) were investigated. CD treatment has the least detrimental effects on color, total chlorophyll contents and ascorbic acid contents of fresh coriander, followed by SH treatment. In addition, CD treatment showed a greater reduction in APC and maintained the microbial load at lower levels than other treatments during the 10-day storage period.

F-soil estimates can be obtained by the low-cost gradient method (GM), but the utility of the method is hindered by uncertainties in the application of published models for the diffusion coefficient. Therefore, to address and resolve these uncertainties, we compared F-soil measured by 2 soil CO2 efflux chambers and F-soil estimated by 16 gas transport models using the GM across 1year. We used 14 published empirical gas diffusion models and 2 in situ models: (1) a gas transfer model called Chamber model obtained using a calibration between the chamber and the gradient method and (2) a diffusion model called SF6 model obtained through an interwell conservative tracer experiment. Most of the published models using the GM underestimated cumulative annual F-soil by 55% to 361%, while the Chamber model closely approximated cumulative F-soil (0.6% error). Surprisingly, the SF6 model combined with the GM underestimated F-soil by 32%. Differences between in situ models could stem from the Chamber model implicitly accounting for production of soil CO2, while the conservative tracer model does not. Therefore, we recommend using the GM only after calibration with chamber measurements to generate reliable long-term ecosystem F-soil measurements. Accurate estimates of F-soil will improve our understanding of soil respiration's contribution to ecosystem fluxes.

Past research shows that species delimitation within Aphelinus is greatly complicated by lack of comprehensive literature and the existence of cryptic species complexes. One of these complexes is the Aphelinus asychis species group. Through the development of a morphological character set, a revision of the Aphelinus asychis species group was conducted. Two new species, Aphelinus sinensis sp. n., and Aphelinus kazakhstanensis sp. n., are described, and the two existing valid species within the asychis group, Aphelinus asychis and Aphelinus semiflavus are redescribed and lectotypes are designated for Aphelinus semiflavus and Aphelinus brevipennis (a junior synonym of A. semiflavus). We also provide a key for identifying species in the asychis group. C1 [Shirley, Xanthe A.; Woolley, James B.] Texas A&M Univ, Dept Entomol, College Stn, TX 77843 USA.

TI Characterizing Movement of Ground-Dwelling Arthropods with a Novel Mark-Capture Method Using Fluorescent Powder SO JOURNAL OF INSECT BEHAVIOR LA English DT Article DE Dispersal; forest floor; insects; invertebrates; sampling ID CARABID BEETLES COLEOPTERA; RELEASE-RECAPTURE; DISPERSAL; FIELD; POPULATIONS; INSECTS; HABITAT; PREDATORS; DYNAMICS; PATTERNS AB A major knowledge gap exists in understanding dispersal potential of ground-dwelling arthropods, especially in forest ecosystems. Movement of the ground-dwelling arthropod community was quantified using a novel mark-capture technique in which three different colored fluorescent powders in two separate mixtures were applied to the floor of a deciduous forest in concentric bands 3, 8, and 15 m from the center of 30 x 30 m experimental plots. The majority (67.1%) of ground-dwelling arthropods did not cross a colored band when fluorescents were mixed with protein powder in 2014. However, when mixed with sand in 2015, 77.3% of captured arthropods were marked with fluorescent powder, with the majority of individuals crossing one band (41.2%), suggesting limited dispersal by most individuals in the community. Only 2.8% and 15.0% of arthropods crossed all three bands in 2014 and 2015, respectively, which further indicates that individuals have limited dispersal. Responses were taxon-specific, and a high proportion of some arthropods such as millipedes and harvestmen crossed two or three bands. Limited dispersal by most individuals may have important implications for the structure and distribution of ground-dwelling arthropod communities, as well as their responses to natural or anthropogenic disturbances. Our results demonstrate the feasibility of this novel technique for self-marking and capturing individuals in the field to investigate dispersal of ground-dwelling arthropods.

While the natural enemy community of H. halys has been evaluated in several agroecosystems, it has not been examined where H. halys overwinters in anthropogenic structures. The aims of the current study were to evaluate 1) whether spider webs commonly found in the home and yard can successfully ensnare H. halys, 2) whether entanglement resulted in consumption by spiders inhabiting the webs, and 3) how frequently H. halys becomes entangled in webs under ambient conditions. To accomplish this, adult H. halys were introduced into webs in and near anthropogenic structures in West Virginia and Maryland, United States, and the behavior of spiders was observed for 5-min intervals at 0, 1, 2, and 24 h after introduction. In addition, a survey of webs was performed to determine the frequency with which spiders naturally capture H. halys inside buildings and in the landscape. Overall, the study found seven spider families in anthropogenic structures. Adult H. halys that were introduced into the webs of Theridiidae, Pholcidae, or Agelenidae had a greater than 50% chance of being ensnared and consumed. Adult H. halys were found naturally most often in webs of Theridiidae. Webs with a funnel or cob web architecture had the greatest probability of ensnaring H. halys, while those with orb structures resulted in the fewest caught. In the wild, 13-20% of spider webs contained dead H. halys. Our results suggest that spiders may be an important contributing factor for mortality of H. halys at overwintering sites, and spiders in or outside homes may help reduce nuisance problems caused by H. halys.

To improve the accuracy, objectivity and efficiency of crop survey estimates, an automated stratification method based on geospatial crop planting frequency and cultivation data is proposed. This paper investigates using 2008-2013 geospatial corn, soyben and wheat planting frequency data layers to create three corresponding single crop specific and one multi-crop specific South Dakota (SD) U.S. ASF stratifications. Corn, soybeans and wheat are three major crops in South Dakota. The crop specific ASF stratifications are developed based on crop frequency statistics derived at the primary sampling unit (PSU) level based on the Crop Frequency Data Layers. The SD corn, soybean and wheat mean planting frequency strata of the single crop stratifications are substratified by percent cultivation based on the 2013 Cultivation Layer. The three newly derived ASF stratifications provide more crop specific information when compared to the current National Agricultural Statistics Service (NASS) ASF based on percent cultivation alone. Further, a multi-crop stratification is developed based on the individual corn, soybean and wheat planting frequency data layers. It is observed that all four crop frequency based ASF stratifications consistently predict corn, soybean and wheat planting patterns well as verified by the 2014 Farm Service Agency (FSA) Common Land Unit (CLU) and 578 administrative data. This demonstrates that the new stratifications based on crop planting frequenby and cultivation are crop type independent and applicable to all major crops. Further, these results indicate that the new crop specific ASF stratifications have great potential to improve ASF accuracy, efficiency and crop estimates.

Enzymatic bioconversion of this substrate offers a reliable strategy for accessing this material under mild reaction conditions. Owing to the complex nature of lignocellulose, many different enzymatic activities are required to function in concert to perform efficient transformation. In nature, large multienzyme complexes are known to effectively hydrolyze lignocellulose into constituent monomeric sugars. We created artificial complexes of enzymes, called rosettazymes, in order to hydrolyze glucuronoxylan, a common lignocellulose component, into its cognate sugar D-xylose and then further convert the D-xylose into D-xylonic acid, a Department of Energy top-30 platform chemical. Four different types of enzymes (endoxylanase, alpha-glucuronidase, beta-xylosidase, and xylose dehydrogenase) were incorporated into the artificial complexes. We demonstrated that tethering our enzymes in a complex resulted in significantly more activity (up to 71%) than the same amount of enzymes free in solution. We also determined that varying the enzyme composition affected the level of complex-related activity enhancement as well as overall yield.

Multiple agencies publish fatality summaries for wildland firefighters; however, the reported number and types vary. At least five different surveillance systems capture deaths, each with varying case definitions and case inclusion/exclusion criteria. Four are population-level systems and one is case-based. System differences create challenges to accurately characterize fatalities.Data within each of the five surveillance systems were examined to better understand the types of wildland firefighter data collected, to assess each system's utility in characterizing wildland firefighter fatalities, and to determine each system's potential to inform prevention strategies. To describe similarities and differences in how data were recorded and characterized, wildland fire deaths for three of the population-based systems were matched and individual fatalities across systems were compared.Between 2001 and 2012, 247 unique deaths were captured among the systems; 73% of these were captured in all three systems. Most common causes of death in all systems were associated with aviation, vehicles, medical events, and entrapments/burnovers. The data show that, although the three systems often report similar annual summary statistics, events captured in each system vary each year depending on the types of events that the system is designed to track, such as inclusion/exclusion of fatalities associated with the Hometown Heroes Survivor Benefits Act of 2003.The overarching and central goal of each system is to collect accurate and timely information to improve wildland firefighter safety and health. Each system is unique and has varying inclusion and exclusion criteria for capturing and tracking different subsets of wildland firefighter tasks and duties. Use of a common case definition and better descriptions and interpretations of the data and the results would help to more accurately characterize wildland firefighter traumatic injuries and illnesses, lessen the likelihood for misinterpretation of wildland firefighter fatality data, and assist with defining the true occupational injury burden within this high-risk population.

An experiment was conducted to assess the influence of nitrate and ammonium forms (NO3(-), NH4+, and mix of NO3- + NH4+), and levels (1.5- 12.0 mM) of N on the growth and nutrition of cacao (Theobroma cacao L). Growth parameters were significantly influenced by N forms, and nitrogen supplied as NH4+ proved better for the growth of cacao compared with NO3- form and mixtures of these two forms. Irrespective of the forms of N, levels of N had no significant effect on plant growth parameters. Nutrient efficiency ratios (NERs) (shoot drymatter produced per unit of nutrient uptake) for macronutrients were sulfur>phosphorus>calcium>magnesium>nitrogen>potassium (S>P>Ca>Mg>N>K) and for micronutrients NERs were in the order of copper>boron>zinc>iron>manganese (Cu>B>Zn>Fe>Mn).

One of the responsible mechanisms is the chronic inflammation driven by obesity. However, it remains to be defined whether diet-induced obesity exacerbates the intestinal inflammatory status by cytokines produced in adipose tissue or the high fat diet first alters the gut microbiota and then drives intestinal inflammation. To address this question, we fed C57BL/6 mice with a high fat diet (HF, 60%) and sacrificed them sequentially after 8, 12, and 16 weeks, and then compositions of gut microbiota and expressions of antimicrobial peptides were determined. The compositions of gut microbiota were altered at 8 wk HF feeding, followed with reduced Paneth antimicrobial peptides lysozyme and Reg III gamma after 12 and 16 wk HF feeding (p < 0.05), whereas elevations of circulating inflammatory cytokines IFN gamma and TNF-alpha were observed until feeding a HF diet for 16 weeks (p < 0.05). These results indicated that high fat diet may stimulate intestinal inflammation via altering gut microbiota, and it occurs prior to the potential influence by circulating inflammatory cytokines. These findings emphasized the importance of microbiota, in addition to adipose tissue per se, in driving intestinal inflammation, which may thereafter promote intestinal tumorigenesis.

TI Pterostilbene-induced changes in gut microbiota composition in relation to obesity SO MOLECULAR NUTRITION & FOOD RESEARCH LA English DT Article DE Akkermansia; Insulin sensitivity; Odoribacter; Polyphenols; Verrucomicrobia ID DIET-INDUCED OBESITY; DEGRADER AKKERMANSIA-MUCINIPHILA; TOTAL PARENTERAL-NUTRITION; COLON-CANCER CELLS; HIGH-FAT; INSULIN-RESISTANCE; FECAL MICROBIOTA; HUMAN FECES; METABOLIC SYNDROME; LIPID-METABOLISM AB Scope: Nutritional interventions based on the use of natural bioactive compounds might offer new possibilities for reshaping obesity-associated bacterial dysregulation or dysbiosis and improving health. We evaluated whether pterostilbene supplementation could induce changes in gut microbiota composition and whether these modifications were associated with improvements in metabolic variables. Methods and results: Zucker (fa/fa) rats were given a standard diet supplemented (n = 10) or not (n = 9) with pterostilbene (15 mg/kg body weight/day) by oral gavage for 6 weeks. Faucal samples at the beginning and at the end of the intervention period were analyzed by Illumina Mi-Seq sequencing approach. Pterostilbene exerted protective antiobesity effects, improved metabolic function (insulin sensitivity), and induced structural changes in gut microbiota composition. A decrease in the levels of Firmicutes and an increase in Verrucomicrobia phyla were detected in the pterostilbene-treated group. Bacterial species belonging to genera Akkermansia and Odoribacter were also increased. A strong inverse correlation between Akkermansia muciniphila and body weight was evidenced. Odoribacter splanchnicus showed a negative correlation with adiposity. Conclusion: Pterostilbene modifies intestinal bacteria composition toward a healthier microbial profile and suggests that the antiobesity effects induced in Zucker rats could be associated with an enrichment of the mucin-degrading bacterial members, namely Akkermansia and Odoribacter genus.

TI Behavioural differences of Heterodera glycines and Meloidogyne incognita infective juveniles exposed to root extracts in vitro SO NEMATOLOGY LA English DT Article DE attraction; head movement; marigold; pepper; root-knot nematode; soybean cyst nematode ID PLANT-PARASITIC NEMATODES; TAGETES-PATULA; KNOT NEMATODES; CHEMOTAXIS; BIOASSAY; TOMATO AB In vitro behaviour of infective second-stage juveniles (J2) of Heterodera glycines and Meloidogyne incognita was compared in the presence and absence of plant root extracts. In an agar plate attraction-retention assay, with samples applied by agar disc infused with water (control) or aqueous test solutions, H. glycines was 15-fold more responsive to a chemical attractant (CaCl2) than was M. incognita. Control discs retained H. glycines at a rate 2.9-fold greater than M. incognita. Crude extracts (slurries; 40 mg dry root (ml water)(-1)) from roots of six plant species (corn, Zea mays; cucumber, Cucumis sativus; marigold, Tagetes patula; mustard, Sinapis alba; pepper, Capsicum annuum; soybean, Glycine max) differentially affected the two nematodes. Cucumber, marigold, pepper and soybean each attracted H. glycines at rates between 2.2-and 3.6-fold greater than controls. No root preparations were attractive to M. incognita, which were significantly repelled by corn, cucumber, mustard and pepper, relative to controls. Preparation of selected root extract supernatants, which involved vacuum drying, decreased the attractiveness of marigold and soybean to H. glycines by 38 and 82%, respectively, but the effect of pepper was unchanged. Supernatant processing had no effect on M. incognita behaviour. In a liquid-based J2 movement assay, root supernatants from marigold, pepper and soybean at 1 mg dry root ml(-1) each decreased the frequency of head movement in H. glycines and M. incognita relative to controls. However, dose responses were detected only with marigold, with maximum decreases in activity at 16 mg dry root ml(-1) for each species. These decreases were significantly different at 46 and 66%, respectively, for H. glycines and M. incognita. The behaviour of the two nematodes was qualitatively different in assays that required detection of signals across a short distance (agar assay), whereas qualitative responses were similar when juveniles were immersed in treatment solution (liquid assay). In the latter, quantitative responses to marigold differed significantly between H. glycines and M. incognita J2.

We evaluated direct effects of predation by large predators on small, specialist carnivores by estimating annual survival and cause-specific mortality. We used known fate models to estimate annual survival of 23 radio-collared short-tailed weasels (Mustela erminea) in western Oregon in 2012-2013. Further, we reviewed published and unpublished studies of radio-tracked weasels (Mustela spp.) in North America, to identify main predators of weasels and survival. If the study did not report survival but did report number of days tracked and cause-specific mortalities, we extrapolated an annual survival index, based on daily survival rates (Mayfield index), to facilitate comparisons between studies. Estimated mean +/- SD annual survival of short-tailed weasels in our study was 0.26 +/- 0.08, and did not vary by season or sex of the weasel. Most (80%) predation mortalities, however, occurred in winter, and were attributed to predatory birds, suspected to be barred owls (Strix varia). For seven North American studies, including ours, we estimated the average annual survival index for M. erminea and Mustela frenata to be 0.37 +/- 0.28. Across studies, most mortality was attributed to predation. Predators killed weasels >2x more frequently in winter when most mortality (86%) was attributed to predatory birds. Mammalian predators, in contrast, killed weasels most frequently in summer (75%). Our results support the hypothesis that predation may play an important role limiting weasel populations in North America.

TI A Pap1-Oxs1 signaling pathway for disulfide stress in Schizosaccharomyces pombe SO NUCLEIC ACIDS RESEARCH LA English DT Article ID TRANSCRIPTION FACTOR PAP1; FISSION YEAST; HYDROGEN-PEROXIDE; OXIDATIVE STRESS; NUCLEAR EXPORT; SEXUAL DEVELOPMENT; PROTEIN; TOLERANCE; H2O2; PHOSPHORYLATION AB We describe a Pap1-Oxs1 pathway for diamide-induced disulfide stress in Schizosaccharomyces pombe, where the nucleocytoplasmic HMG protein Oxs1 acts cooperatively with Pap1 to regulate transcription. Oxs1 and Pap1 form a complex when cells are exposed to diamide or Cd that causes disulfide stress. When examined for promoters up-regulated by diamide, effective Pap1 binding to these targets requires Oxs1, and vice versa. With some genes, each protein alone enhances transcription, but the presence of both exerts an additive positive effect. In other genes, although transcription is induced by diamide, Oxs1 or Pap1 plays a negative role with full derepression requiring loss of both proteins. In a third class of genes, Oxs1 positively regulates expression, but in its absence, Pap1 plays a negative role. The Oxs1-Pap1 regulatory interaction appears evolutionarily conserved, as heterologous (human, mouse and Arabidopsis) Oxs1 and Pap1-homologues can bind interchangeably with each other in vitro, and at least in the fission yeast, heterologous Oxs1 and Pap1-homologues can substitute for S. pombe Oxs1 and Pap1 to enhance stress tolerance.

TI The Influence of Package Size and Flute Type of Corrugated Boxes on Load Bridging in Unit Loads SO PACKAGING TECHNOLOGY AND SCIENCE LA English DT Article DE unit load; pallet; corrugated box; load bridging; stress distribution AB Shipping pallets often are designed with the assumption that the payload carried is flexible and uniformly distributed on the pallet surface. However, packages on the pallet can act as a series of discrete loads, and the physical interactions among the packages can add stiffness to the pallet/load combination. The term 'load bridging' has been used to describe this phenomenon. The study reported in this paper investigated the relationships of package size, corrugated flute type and pallet stiffness to load bridging and the resulting unit-load deflection. The experimental results indicated that an increase in box size changed the unit-load deflection by as much as 75%. Flute type was found to impact load bridging and the resulting unit-load deflection. Changing the corrugated box flute type from B-flute or BC-flute to E-flute reduces the unit-load deflection by as much as 40%. Also, experimental data indicates that the effect of package size and corrugated board flute type on pallet deflection is the greatest for low stiffness pallets. The results provide information that can be used to design unit loads that use material more efficiently. Copyright (C) 2017 John Wiley & Sons, Ltd.

The current study was designed to further characterize the nature of the protection provided by AtNPR1 expression and its limitations. Green Fluorescent Protein-expressing Fov11 was generated and used to study the progression of the disease within the plant. The results show that the spread of the pathogen was slower in the AtNPR1-transformants compared to the wild type plants. Transcript analysis in the seedling root and hypocotyl showed that the transgenic lines are capable of launching a stronger defense response when infected with Fov11. We further confirmed that AtNPR1 transformants showed greater degree of tolerance to Fov11. However, little or no protection was observed against a related, but more virulent isolate, Fov43, and a highly virulent isolate, CA9.

TI Genetic Architecture of Flowering-Time Variation in Brachypodium distachyon SO PLANT PHYSIOLOGY LA English DT Article ID QUANTITATIVE TRAIT LOCI; BARLEY HORDEUM-VULGARE; PHYTOCHROME-C; INBRED LINES; VERNALIZATION GENES; GROWTH HABIT; SHOOT APEX; WHEAT; ADAPTATION; MODEL AB The transition to reproductive development is a crucial step in the plant life cycle, and the timing of this transition is an important factor in crop yields. Here, we report new insights into the genetic control of natural variation in flowering time in Brachypodium distachyon, a nondomesticated pooid grass closely related to cereals such as wheat (Triticum spp.) and barley (Hordeum vulgare L.). A recombinant inbred line population derived from a cross between the rapid-flowering accession Bd21 and the delayed-flowering accession Bd1-1 were grown in a variety of environmental conditions to enable exploration of the genetic architecture of flowering time. A genotyping-by-sequencing approach was used to develop SNP markers for genetic map construction, and quantitative trait loci (QTLs) that control differences in flowering time were identified. Many of the flowering-time QTLs are detected across a range of photoperiod and vernalization conditions, suggesting that the genetic control of flowering within this population is robust. The two major QTLs identified in undomesticated B. distachyon colocalize with VERNALIZATION1/PHYTOCHROME C and VERNALIZATION2, loci identified as flowering regulators in the domesticated crops wheat and barley. This suggests that variation in flowering time is controlled in part by a set of genes broadly conserved within pooid grasses.

Katzir, Nurit Fei, Zhangjun Welsch, Ralf Li, Li Burger, Joseph Tadmor, Yaakov TI Distinct Mechanisms of the ORANGE Protein in Controlling Carotenoid Flux SO PLANT PHYSIOLOGY LA English DT Article ID MELON CUCUMIS-MELO; BETA-CAROTENE; PHYTOENE SYNTHASE; ARABIDOPSIS LEAVES; ALLELIC VARIATION; FRUIT COLORATION; PHOTOSYSTEM-II; POTATO-TUBERS; ACCUMULATION; GENE AB beta-Carotene adds nutritious value and determines the color of many fruits, including melon (Cucumis melo). In melon mesocarp, beta-carotene accumulation is governed by the Orange gene (CmOr) golden single-nucleotide polymorphism (SNP) through a yet to be discovered mechanism. In Arabidopsis (Arabidopsis thaliana), OR increases carotenoid levels by posttranscriptionally regulating phytoene synthase (PSY). Here, we identified a CmOr nonsense mutation (Cmor-low beta) that lowered fruit beta-carotene levels with impaired chromoplast biogenesis. Cmor-low beta exerted a minimal effect on PSY transcripts but dramatically decreased PSY protein levels and enzymatic activity, leading to reduced carotenoid metabolic flux and accumulation. However, the golden SNP was discovered to not affect PSY protein levels and carotenoid metabolic flux in melon fruit, as shown by carotenoid and immunoblot analyses of selected melon genotypes and by using chemical pathway inhibitors. The high beta-carotene accumulation in golden SNP melons was found to be due to a reduced further metabolism of beta-carotene. This was revealed by genetic studies with double mutants including carotenoid isomerase (yofi), a carotenoid-isomerase nonsense mutant, which arrests the turnover of prolycopene. The yofi F2 segregants accumulated prolycopene independently of the golden SNP. Moreover, Cmor-low beta was found to inhibit chromoplast formation and chloroplast disintegration in fruits from 30 d after anthesis until ripening, suggesting that CmOr regulates the chloroplast-to-chromoplast transition. Taken together, our results demonstrate that CmOr is required to achieve PSY protein levels to maintain carotenoid biosynthesis metabolic flux but that the mechanism of the CmOr golden SNP involves an inhibited metabolism downstream of beta-carotene to dramatically affect both carotenoid content and plastid fate.

In general, CIIIPRX genes encode a large number of isozymes with ranges of in vitro substrate specificities. In order to elucidate the mode of substrate specificity of these enzymes, we characterized one of the CIIIPRXs (PviPRX9) from switchgrass ( Panicum virgatum), a strategic plant for second-generation biofuels. The crystal structure, kinetic experiments, molecular docking, as well as expression patterns of PviPRX9 across multiple tissues and treatments, along with its levels of coexpression with the majority of genes in the monolignol biosynthesis pathway, revealed the function of PviPRX9 in lignification. Significantly, our study suggested that PviPRX9 has the ability to oxidize a broad range of phenylpropanoids with rather similar efficiencies, which reflects its role in the fortification of cell walls during normal growth and root development and in response to insect feeding. Based on the observed interactions of phenylpropanoids in the active site and analysis of kinetics, a catalytic mechanism involving two water molecules and residues histidine-42, arginine-38, and serine-71 was proposed. In addition, proline-138 and gluntamine-140 at the 137P-X-P-X140 motif, leucine-66, proline-67, and asparagine-176 may account for the broad substrate specificity of PviPRX9. Taken together, these observations shed new light on the function and catalysis of PviPRX9 and potentially benefit efforts to improve biomass conservation properties in bioenergy and forage crops.

This study tested the application of leaf hyperspectral reflectance (lambda = 5002,400 nm) as a high-throughput phenotyping approach for rapid and accurate assessment of leaf photosynthetic and biochemical traits in maize (Zea mays). Leaf traits were measured with standard wet-laboratory and gas-exchange approaches alongside measurements of leaf reflectance. Partial least-squares regression was used to develop a measure of leaf chlorophyll content, nitrogen content, sucrose content, specific leaf area, maximum rate of phosphoenolpyruvate carboxylation, [CO2]-saturated rate of photosynthesis, and leaf oxygen radical absorbance capacity from leaf reflectance spectra. Partial least-squares regression models accurately predicted five out of seven traits and were more accurate than previously used simple spectral indices for leaf chlorophyll, nitrogen content, and specific leaf area. Correlations among leaf traits and statistical inferences about differences among genotypes and treatments were similar for measured and modeled data. The hyperspectral reflectance approach to phenotyping was dramatically faster than traditional measurements, enabling over 1,000 rows to be phenotyped during midday hours over just 2 to 4 d, and offers a nondestructive method to accurately assess physiological and biochemical trait responses to environmental stress.

We performed quantitative proteomics on plasma membrane-enriched samples from Arabidopsis (Arabidopsis thaliana) treated with bacterial flagellin. We identified multiple receptor-like protein kinases changing in abundance, including cysteine (Cys)-rich receptor-like kinases (CRKs) that are up-regulated upon the perception of flagellin. CRKs possess extracellular Cys-rich domains and constitute a gene family consisting of 46 members in Arabidopsis. The single transfer DNA insertion lines CRK28 and CRK29, two CRKs induced in response to flagellin perception, did not exhibit robust alterations in immune responses. In contrast, silencing of multiple bacterial flagellin-induced CRKs resulted in enhanced susceptibility to pathogenic Pseudomonas syringae, indicating functional redundancy in this large gene family. Enhanced expression of CRK28 in Arabidopsis increased disease resistance to P. syringae. Expression of CRK28 in Nicotiana benthamiana induced cell death, which required intact extracellular Cys residues and a conserved kinase active site. CRK28-mediated cell death required the common receptor-like protein kinase coreceptor BAK1. CRK28 associated with BAK1 as well as the activated FLAGELLIN-SENSING2 (FLS2) immune receptor complex. CRK28 self-associated as well as associated with the closely related CRK29. These data support a model where Arabidopsis CRKs are synthesized upon pathogen perception, associate with the FLS2 complex, and coordinately act to enhance plant immune responses.

However, the molecular mechanisms underlying these antagonistic effects are not well understood. In this study, we characterized the association between a pathogenesis-related PR-10 family gene from rose (RhPR10.1) and the hormonal regulation of flower senescence. Quantitative reverse transcription PCR analysis showed that RhPR10.1 was expressed at high levels during senescence in different floral organs, including petal, sepal, receptacle, stamen, and pistil, and that expression was induced by ethylene treatment. Silencing of RhPR10.1 expression in rose plants by virusinduced gene silencing accelerated flower senescence, which was accompanied by a higher ion leakage rate in the petals, as well as increased expression of the senescence marker gene RhSAG12. CTK content and the expression of three CTK signaling pathway genes were reduced in RhPR10.1-silenced plants, and the accelerated rate of petal senescence that was apparent in the RhPR10.1-silenced plants was restored to normal levels by CTK treatment. Finally, RhHB6, a homeodomain-Leu zipper I transcription factor, was observed to bind to the RhPR10.1 promoter, and silencing of its expression also promoted flower senescence. Our results reveal an ethylene-induced RhHB6-RhPR10.1 regulatory module that functions as a brake of ethylenepromoted senescence through increasing the CTK content.

Their genomes contain about 250-400 nucleotides, depending on viroid species. Members of the family Pospiviroidae, like the Potato spindle tuber viroid (PSTVd), replicate via an asymmetric rolling-circle mechanism using the host DNA-dependent RNA-Polymerase II in the nucleus, while members of Avsunviroidae are replicated in a symmetric rolling-circle mechanism probably by the nuclear-encoded polymerase in chloroplasts. Viroids induce the production of viroid-specific small RNAs (vsRNA) that can direct (post-)transcriptional gene silencing against host transcripts or genomic sequences. Here, we used deep-sequencing to analyze vsRNAs from plants infected with different PSTVd variants to elucidate the PSTVd quasipecies evolved during infection. We recovered several novel as well as previously known PSTVd variants that were obviously competent in replication and identified common strand-specific mutations. The calculated mean error rate per nucleotide position was less than 5 x 10(-3), quite comparable to the value of 2: 5 x 10(-3) reported for a member of Avsunviroidae. The resulting error threshold allows the synthesis of longer-than-unit-length replication intermediates as required by the asymmetric rolling-circle mechanism of members of Pospiviroidae.

Wilderness also attracts amenity migrants and out-of-region investments into surrounding regional economies. To investigate the amount and types of employment and income generated by Wilderness visitation, we conducted an economic contribution analysis of aggregate national visitor expenditures. The U.S. Forest Service National Visitor Use and Monitoring (NVUM) economic spending profiles were used to construct types and amounts of Wilderness visitor spending and were applied to an estimated 9.9 million annual visitors across federal agencies. IMPLAN modeling software was used to estimate total effects and multipliers for output, employment, income, and value added. Results show that some $500 million is annually spent in communities adjacent to Wilderness, generating a direct effect of 5,700 jobs and a total output effect over $700 million across numerous industries ($2012 including indirect and induced effects).

However, in recent years some farmers have started rice-based rotations with one or more upland crops per year. The trends for increased grain yields with this new system raises the question as to whether the introduction of upland crops affects properties of alluvial clay paddy soil. This was evaluated in the present study, which was performed at 40 paddy fields in the Vietnamese Mekong Delta under four different cropping systems (10 farms per system) on paddy rice soils: RRR; crop rotation with two rice crops and one upland crop per year (RUR); crop rotation with one rice and two upland crops per year (RUU); and upland crop (UUU). Soil samples were collected at depths of 0-10, 10-20 and 20-30cm. Most soil properties differed significantly between the RRR and the RUR, RUU or UUU. The RUR, RUU and UUU systems alleviated soil compaction, resulting in reduced penetration resistance and bulk density and increased total and macroporosity at 20-30cm depth. In addition, aggregate stability index and plant-available water capacity were higher for RUR, RUU and UUU compared with RRR at the 20-30cm depth. Average soil organic carbon (SOC) stocks ranged from 59.3tha(-1) in UUU to 72.3tha(-1) in RUR, with SOC stocks in RRR and RUU being intermediate (66.4 and 68.3tha(-1)) and not significantly different to that of the RUR system. Carbon hydrolysable by HCl (C-hydrolysable) was 74-84% greater in the RUR, RUU and UUU than in RRR systems.

TI Cellulosic ethanol byproducts as a bulking agent SO TAPPI JOURNAL LA English DT Article ID MICROFIBRILLATED CELLULOSE; STRENGTH PROPERTIES; WOOD POWDER; PAPER; SCALE; PULP; BIOCONVERSION; NETWORK; TENSILE; FINES AB Financial enhancement of biomass value prior to pulping requires subsequent use of remaining materials; e.g., high value use of remaining stock material after cellulosic ethanol production would improve the economics for cellulosic ethanol. In this work, use of enzymatic hydrolysis residual solids (EHRS), a cellulosic ethanol byproduct, were investigated as a bulking agent. The study examined the effect across several grammages, 20 g/m(2) -200 g/m(2), and EHRS substitution levels, 10%, 15%, and 20%. EHRS retention was examined with light scattering. EHRS loading increased bulk while reducing tensile strength, compression strength, and stiffness. Application: Byproducts of cellulosic ethanol production can be used as a bulking agent.

Cryopreservation refers to the storage of plant material at ultralow temperatures in liquid nitrogen. A procedure for cryopreservation of polyembryonic seeds was improved for selected citrus cultivars from Turkey. Seed dehydration was performed at different exposure times, in sterile conditions of a laminar flow-hood. The tested cultivars showed the highest tolerance to low temperature storage when the seeds were first dehydrated to a moisture content of 21.8% for Poncirus trifoliata Raf. x Citrus sinensis Osb. and to 17.6% for Citrus limonia Osbeck. The postcryopreservation germinability ranged from 73.3% (Poncirus trifoliata Raf. x C. sinensis Osb. and Fortunella margarita (Lour.) Swingle) to 93.3% (C. jambhiri Lush.). Dehydration was beneficial for germination of seeds from all of the tested citrus species after the liquid nitrogen exposure. Seedlings derived from cryopreserved seeds had well-formed shoots and roots and were easily acclimated to greenhouse conditions.

E. dicentrarchi was found in various developmental stages in most segments, mainly anterior, of the digestive tract. In infected segments of the digestive tract, merogonic and gamogonic stages were located in the enterocyte cytoplasm, whereas sporogonic stages were situated in the epithelium and occasionally beneath it, in the lamina propria. Most oocysts in the lumen of the digestive tract were completely sporulated, indicating endogenous sporulation. E. dicentrarchi infection caused localised histopathological changes, restricted primarily to individual epithelial cells. Additionally, the results of our preliminary study suggest that oral administration of potentiated sulphonamide Trimetosul (R) (trimethoprimsulfadiazine) may be effective against E. dicentrarchi infection.

TI Strengths and weaknesses of temporal stability analysis for monitoring and estimating grid-mean soil moisture in a high-intensity irrigated agricultural landscape SO WATER RESOURCES RESEARCH LA English DT Article DE wireless sensor network; temporal stability; remote sensing; representativeness ID REMOTE-SENSING FOOTPRINTS; WIRELESS SENSOR NETWORK; HEIHE RIVER-BASIN; SPATIAL VARIABILITY; WATER CONTENT; SPATIOTEMPORAL VARIABILITY; TIME STABILITY; LOESS-PLATEAU; LAND-USE; CHINA AB Monitoring and estimating grid-mean soil moisture is very important for assessing many hydrological, biological, and biogeochemical processes and for validating remotely sensed surface soil moisture products. Temporal stability analysis (TSA) is a valuable tool for identifying a small number of representative sampling points to estimate the grid-mean soil moisture content. This analysis was evaluated and improved using high-quality surface soil moisture data that were acquired by a wireless sensor network in a high-intensity irrigated agricultural landscape in an arid region of northwestern China. The performance of the TSA was limited in areas where the representative error was dominated by random events, such as irrigation events. This shortcoming can be effectively mitigated by using a stratified TSA (STSA) method, proposed in this paper. In addition, the following methods were proposed for rapidly and efficiently identifying representative sampling points when using TSA. (1) Instantaneous measurements can be used to identify representative sampling points to some extent; however, the error resulting from this method is significant when validating remotely sensed soil moisture products. Thus, additional representative sampling points should be considered to reduce this error. (2) The calibration period can be determined from the time span of the full range of the grid-mean soil moisture content during the monitoring period. (3) The representative error is sensitive to the number of calibration sampling points, especially when only a few representative sampling points are used. Multiple sampling points are recommended to reduce data loss and improve the likelihood of representativeness at two scales.

TI An analytical test case for snow models SO WATER RESOURCES RESEARCH LA English DT Article DE snow hydrology; model evaluation; numerical modeling ID LAND-SURFACE MODELS; SOIL-MOISTURE; WATER-FLOW; NUMERICAL-SOLUTION; ALPINE SITE; ENERGY; COMPLEXITY; TRANSPORT; PERFORMANCE; EQUATION AB This paper develops general analytical solutions for examples of water movement through snow and compares the derived analytical solutions to numerical simulations from a coupled energy and mass balance model. The intended use of the test cases is to evaluate the impact of different numerical approximations, especially different vertical discretization strategies and different time stepping schemes. The analytical solutions provide both outflow from the snowpack, as well as vertical profiles of temperature and volumetric liquid water content at different times throughout the analysis period. The derived analytical solutions have close correspondence with model simulations in most cases. The most pronounced differences between the numerical simulations and the analytical solutions are for the fresh snow test case, where the numerical simulations predict earlier arrival of snowpack outflow. The analytical solutions provide a useful test case for physically motivated snow models because the solutions can be used to evaluate the coupling of hydrology and thermodynamics as well as the unsaturated flow of water through porous media.

TI Purple Nutsedge (Cyperus rotundus) Tuber Production and Viability Are Reduced by Imazapic SO WEED SCIENCE LA English DT Article DE Imazapic; purple nutsedge; Cyperus rotundus L.; CYPRO ID PEANUT ARACHIS-HYPOGAEA; AC 263,222; WEED MANAGEMENT; ESCULENTUS; INTERFERENCE; SYSTEMS; MULCH AB Weeds exploit underutilized space, causing economic losses in cropping systems. Weed management tactics alter that underutilized space until the crop can mature and efficiently use that space. One tactic is to reduce the weed propagules (e.g., seeds and tubers) that persist quiescently in the soil, which includes minimizing production and addition of new propagules to the soil. Purple nutsedge is a problematic weed around the globe, persisting between growing seasons as tubers in the soil. Imazapic is a peanut herbicide often used in Georgia for control of purple nutsedge. The objective of the experiment was to evaluate the effect of various rates of imazapic on purple nutsedge tuber production. Single presprouted purple nutsedge tubers were transplanted into outdoor microplots and treated after 6 wk of growth with six rates of imazapic (5 to 140 g ai ha(-1)) POST. A nontreated control was included. All emerged shoots at the time of application were marked with plastic rings; this allowed for classification of tubers at exhumation as (1) tubers attached to shoots that were emerged at time of application, (2) tubers attached to shoots that emerged after application, and (3) tubers without an aerial shoot during the study. At 7 wk after application, the tubers in the microplots were exhumed, classified, and quantified, and their ability to sprout was evaluated. In the nontreated control, there were 544 total tubers, with a log-logistic regression model describing the declining tuber population with increasing imazapic rate. The rate of imazapic that reduced total tuber population 50% (I-50) was 36 g ha(-1). In the nontreated control, there were 161 tubers attached to shoots that emerged, as when compared with plots that received an imazapic application that had an I-50 = 60 g ha(-1). Viability of purple nutsedge tubers was 44% at 70 g ha(-1) imazapic, suggesting the action of the herbicide may have rendered the tubers nonviable after new shoots were produced. The final classification of tubers included those that did not have an aerial shoot during the study. These were tubers in which apical dominance suppressed shoot development or were likely the most recent tubers to develop. Of the three classes, the tubers without shoots were the most prevalent in the nontreated control, with 358 tubers and an I-50 = 18 g ha(-1). Imazapic controls purple nutsedge foliage but also reduces the number of new tubers produced, and overall tuber viability and is a valuable tool in management of the long-term population density of this weed.

The Coastal Heathland Cutworm, Abagrotis nefascia (Smith, 1908), and the Dune Noctuid, Sympistis riparia (Morrison, 1875), are unrelated species of psammophilic noctuines (Lepidoptera: Noctuidae) regularly encountered on a localized basis in coastal southern New England and New York, and whose precise life history requirements are undocumented. We inferred and, based on field observation and rearing, corroborated beach plum as a larval host for these species in Massachusetts; the plant's role in sustaining other moths with limited or contracting regional distributions is discussed. Sympistis riparia, belonging to a widely distributed complex of closely related species, has been associated specifically with both maritime and freshwater dunes. The eastern populations of Abagrotis nefascia represent a conspicuous range disjunction, separated from the nearest western populations by more than 2000 miles, and originally described by Franclemont as race benjamini of A. crumbi, both later synonymized with A. nefascia. Following examination of types and other material, an evaluation of putatively diagnostic features from both the original description and our own observations, genitalic characters, and the results of provisional barcode analyses, Abagrotis benjamini Franclemont, stat. rev., is elevated to the rank of a valid species rather than representing eastern populations of Abagrotis nefascia (=crumbi) to which it originally referred.

TI STORED GRAIN VOLUME MEASUREMENT USING A LOW DENSITY POINT CLOUD SO APPLIED ENGINEERING IN AGRICULTURE LA English DT Article DE Grain surface; Spatial modeling; Stored grain management ID COMPRESSIBILITY; WHEAT AB This technical note presents the development of a new apparatus and data processing method to accurately estimate the volume of stored grain in a bin. Specifically, it was developed to account for the variability in surface topography that can occur in large diameter bins when partially unloaded. This was accomplished using a laser distance meter to create a low density point cloud, from which a surface was interpolated using ArcMap geoprocessing tools. The manually controlled and portable system was designed to hold the laser distance meter and provided a common reference point. The data from the laser distance meter was transmitted to a tablet PC via Bluetooth. Measurement of an empty hopper bottom bin (4.6 m in diameter and 6.5 m tall) demonstrated that the system was able to measure a known volume within 0.02%, and repeated measures of an empty flat bottom bin (1.8 m in diameter, and 5.7 m tall) were within 0.29% of the known volume. Two applications are presented which highlight the system's ability to capture complex surfaces, as well as limitations that result from fill scenarios where the field of view was limited.

TI FIELD-OBSERVED ANGLES OF REPOSE FOR STORED GRAIN IN THE UNITED STATES SO APPLIED ENGINEERING IN AGRICULTURE LA English DT Article DE Angle of repose; Moisture; Grain bins; Corn; Wheat; Sorghum; Barley; Soybeans; Oats AB Bulk grain angle of repose (AoR) is a key parameter for inventorying grain, predicting flow characteristics, and designing bins and grain handling systems. The AoR is defined for two cases, piling (dynamic) or emptying (static), and usually varies with grain type. The objective of this study was to measure piling angles of repose for corn, sorghum, barley, soybeans, oats, and hard red winter (HRW) wheat in steel and concrete bins in the United States. Angles were measured in 182 bins and 7 outdoor piles. The piling AoR for corn ranged from 15.7 degrees to 30.2 degrees (median of 20.4 degrees and standard deviation of 3.8 degrees). Sorghum, barley, soybeans, oats, and HRW wheat also exhibited a range of AoR with median values of 24.6 degrees, 21.0 degrees, 23.9 degrees, 25.7 degrees, and 22.2 degrees, respectively. Angles of repose measured for the seven outdoor piles were within the ranges measured for the grain bins. No significant correlation was observed between AoR and moisture content within the narrow range of observed moisture contents, unlike previous literature based on laboratory measurement of grain samples with wider ranges of moisture content. Overall, the average measured piling AoR were lower than typical values cited in MWPS-29, but higher than some laboratory measurements.

Vanillin, melamine, and sugar were mixed together at 10 different concentration level (1% to 10%, w/w) into powdered non-dairy creamer. SMA was used to decompose the complex multi-component spectra and extract the pure component spectra and corresponding contribution images. Spectral information divergence (SID) values of the extracted pure component spectra and reference component spectra were computed to identify the components corresponding to the extracted spectra. The contribution images obtained via SMA were used to create Raman chemical images of the mixtures samples, to which threshold values were applied to obtain binary detection images of the components at all concentration levels. The detected numbers of pixels of each component in the binary images was found to be strongly correlated with the actual sample concentrations (correlation coefficient of 0.99 for all components). The results show that this method can be used for simultaneous identification of different components and estimation of their concentrations for authentication or quantitative inspection purposes.

Samples were prepared by mixing four kinds of soybean protein products (Arconet, toasted soy grits, Profam and textured vegetable protein (TVP)) with ground beef (content from 0%-100%). NIR spectra of meat mixtures were measured with dispersive (400-2500 nm) and Fourier transform NIR (FT-NIR) spectrometers (1000-2500 nm). Partial least squares (PLS) regression with full leave-one-out cross-validation was used to build prediction models. The results based on dispersive NIR spectra revealed that the coefficient of determination for cross-validation (R-cv(2)) ranged from 0.91 for toasted soy grits to 0.99 for Arconet. The results based on FT-NIR spectra exhibited the best prediction for toasted soy grits (R-cv(2) = 0.99) and R-cv(2) > 0.98 for the other three soy types. For identification of different types of soy products, support vector machine (SVM) classification was used and the total accuracy for dispersive NIR and FT-NIR was 95% and 83.33%, respectively. These results suggest that either dispersive NIR or FT-NIR spectroscopy could be used to predict the content and the discrimination of different soy products added in ground beef products. In application, FT-NIR spectroscopy methods would be recommended if time is a consideration in practice. C1 [Jiang, Hongzhe; Wang, Wei] China Agr Univ, Coll Engn, Beijing 100083, Peoples R China.

Components of the system include a semi-autonomous cart, a gated-intensified camera, a spectral adapter, a frequency-triple Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) laser, and optics to convert the Gaussian laser beam into a line-illumination source. The front wheels of the cart are independently powered by stepper motors that support stepping or continuous motion. When stepping, a spreadsheet is used to program parameters of image sets to be acquired at each step. For example, the spreadsheet can be used to set delays before the start of image acquisitions, acquisition times, and laser attenuation. One possible use of this functionality would be to establish acquisition parameters to facilitate the measurement of fluorescence decay-curve characteristics. The laser and camera are mounted on an aluminum plate that allows the optics to be calibrated in a laboratory setting and then moved to the cart. The system was validated by acquiring images of fluorescence responses of spinach leaves and dairy manure.

The mean spectra of the 95 matured tomato samples were extracted from the hyperspectral images, and multivariate calibration models were built by using partial least squares (PLS) regression with different preprocessing spectra. The results showed that the regression model developed by PLS regression based on Savitzky-Golay (S-G) first-derivative preprocessed spectra resulted in better performance for MC, pH, and the smoothing preprocessed spectra-based model resulted in better performance for SSC in intact tomatoes compared to models developed by other preprocessing methods, with correlation coefficients (r(pred)) of 0.81, 0.69, and 0.74 with root mean square error of prediction (RMSEP) of 0.63%, 0.06, and 0.33% Brix respectively. The full wavelengths were used to create chemical images by applying regression coefficients resulting from the best PLS regression model. These results obtained from this study clearly revealed that hyperspectral imaging, together with suitable analysis model, is a promising technology for the nondestructive prediction of chemical components in intact tomatoes.

However, complement activation is also implicated in the progression and complication of immune dysfunctions such as sepsis. Microparticle (MP) biomaterials capable of tuning the local magnitude of serum complement activation could improve complement-mediated cytotoxicity to serum-resistant bacteria or calm an overactive immune response during sepsis. We demonstrate that model Fc-functionalized microparticles can be designed to either enhance or diminish the local cytotoxic effect of complement activation in human serum. The particles were formed with either the antibody Fc domains oriented outward from the particle surface or randomly adsorbed in a nonoriented fashion. In the oriented Fc form, complement products were directly sequestered to the particle surface, including C5a, a potent anaphylatoxin that, when elevated, is associated with poor sepsis prognosis. The oriented particle also lowered the cytotoxicity of serum and thus decreased the antibiotic effect when compared to serum alone. Conversely, the non-oriented microparticles were found to sequester similar levels of C5a, but much lower levels of iC3b and TCC on the microparticle surface, thereby increasing the amount of the soluble terminal complement complex. In addition, the non-oriented microparticles extend the distance over which TCC forms and enhance serum cytotoxicity to bacteria. Together, these two types of complement-modulating particles provide the first biomaterial that can functionally modify the range of complement activation at sites distant from the particle surface. Thus, biomaterials that exploit Fc presentation provide new possibilities to functionally modulate complement activation to achieve a desired clinical result.

The results showed Saeman model accurately fitted the pretreatment process. According to this kinetic model, a maximum hemicellulose hydrolysis yield was achieved at a treatment time of 75 min with a temperature of 145 degrees C. Meantime, the concentrations of acetic acid, hydroxymethylfurfural (HMF), and furfural were 1.54, 0.60, and 1.15 g L-1, respectively. Also, a Lorentzian function described the relationship between total sugar yield and pretreatment factors: temperature and time. The regression parameters from this mathematical fitting have accurately reflected the maximum total sugar yield and the optimal treatment conditions were determined to be 145 degrees C and 110 min.

However, little is known on the consequences of therapeutic intervention on the clonal composition of solid tumors. Experimental Design: Here, we used 33 single cell-derived subclones generated from five clinical glioblastoma specimens for exploring intra-and interindividual spectra of drug resistance profiles in vitro. In a personalized setting, we explored whether differences in pharmacologic sensitivity among subclones could be employed to predict drug-dependent changes to the clonal composition of tumors. Results: Subclones from individual tumors exhibited a remarkable heterogeneity of drug resistance to a library of potential antiglioblastoma compounds. A more comprehensive intratumoral analysis revealed that stable genetic and phenotypic characteristics of coexisting subclones could be correlated with distinct drug sensitivity profiles. The data obtained from differential drug response analysis could be employed to predict clonal population shifts within the naive parental tumor in vitro and in orthotopic xenografts. Furthermore, the value of pharmacologic profiles could be shown for establishing rational strategies for individualized secondary lines of treatment. Conclusions: Our data provide a previously unrecognized strategy for revealing functional consequences of intratumor heterogeneity by enabling predictive modeling of treatmentrelated subclone dynamics in human glioblastoma.

More importantly, to enable optimization of the hardwood lumber sawing process, a fast Means of evaluating the potential value of boards before they are sawn is necessary. As log and lumber scanning systems become prevalent and common, these needs become more pressing. From an automation perspective, the NHLA lumber grades are difficult to implement efficiently in a computer program. Exhaustive approaches that examine every potential cutting size and combination to determine the grade give accurate grading solutions, at the cost of computation time. Other approaches have examined heuristic methods that implement key parts of the grading rules, or used artificial neural network methods, both with the loss of accuracy. Here, a different approach to computerized grading is examined that takes a hybridized approach using projected yield from cut-up simulation and neural network methods. This new hybrid approach has the advantage of both accuracy and high-processing speed. Such an approach lends itself to log sawing optimization with respect to NHLA grades and market values when internal log defect information is known. Published by Elsevier B.V.

Even after intensive clarification and refining, trace colloidal impurities on white (refined) sugar remain to cause a problem known as acid beverage floc. Acid beverage floc is an example of DLVO-type aggregation of oppositely charged particles at decreased pH. Examples of irreversible aggregates include starch ghost and recalcitrant organomineral composites formed at elevated temperature that resist heat transfer. Fundamental knowledge in aggregation kinetics is necessary to predict the occurrence of undesirable aggregates, as pH, ionic strength, temperature, and sucrose concentration change during the processing of sugarcane/beet juice.

Paul TI Validation of Fusarium Head Blight Resistance QTL in US Winter Wheat SO CROP SCIENCE LA English DT Article ID QUANTITATIVE TRAIT LOCI; RECOMBINANT INBRED POPULATION; DEOXYNIVALENOL CONTENT; REGISTRATION; ERNIE; ACCUMULATION; CULTIVARS; SELECTION; ARINA AB Fusarium head blight (FHB), primarily caused by Fusarium graminearum Schwabe [telemorph: Gibberella zeae Schw. (Petch)], can significantly reduce the grain quality of wheat (Triticum aestivum L.) due to mycotoxin contamination. Two US soft red winter wheat cultivars, Bess and NC-Neuse, have moderate resistance to FHB. The objective of this study was to validate genomic regions associated with FHB resistance identified in previous studies involving NC-Neuse and the cultivar Truman, a full-sib of Bess. A total of 98 doubled haploid lines derived from the cross Bess 'NC-Neuse were evaluated in inoculated, mist-irrigated field nurseries. The lines were evaluated for FHB incidence, severity, Fusarium-damaged kernels, and deoxynivalenol content in seven environments between 2011 and 2014. A 3338-cM linkage map was developed based on 4014 simple sequence repeat and single nucleotide polymorphism markers. Twelve quantitative trait loci (QTL) associated with FHB resistance were identified. NC-Neuse alleles provided resistance at QTL on five chromosomes and Bess alleles provided resistance at QTL on five other chromosomes. Alignment of linkage maps revealed that five of these QTL were overlapping with previously identified regions. Quantitative trait loci on chromosomes 1A, 4A, and 6A identified in this study overlapped with QTL regions identified in NC-Neuse, and QTL identified on chromosomes 2B and 3B overlapped with QTL regions identified in Truman. A preliminary test using Kompetitive Allele-Specific polymerase chain reaction assays on recent Uniform Southern Winter Wheat Scab Nursery entries showed that the assays developed for Qfhb. nc-2B. 1 may be good candidates for use in marker-assisted selection.

In the current study, two cycles of divergent selection for fiber upper-half mean length (UHML) and bundle strength (Str) were conducted within five diverse parental combinations selected based on their potential for the genetic improvement of fiber quality. Realized heritability estimates for UHML and Str were calculated for each cycle, and correlated responses among fiber properties and lint percent were measured as they responded to selection for UHML and Str. The results suggest that early-generation selection for UHML and Str is an effective strategy for the genetic improvement of fiber quality at College Station, TX. Although UHML and Str were consistently negatively correlated with lint percent, the results demonstrate that sufficient variation for fiber quality exists within the Texas A&M AgriLife Research upland cotton germplasm to improve UHML and Str without a concomitant reduction in lint percent. A negative phenotypic correlation between UHML and fiber elongation at break was also observed and was independent of the association between Str and fiber elongation at break in multiple populations. These findings suggest that further investigation into the relationship between UHML and fiber elongation within the Texas A&M AgriLife Research germplasm is warranted. C1 [Hugie, Kari L.; Smith, C.

Diversity for SNF within dry bean germplasm is recognized, and regions of the genome associated with SNF traits have recently been identified. In the current study a mapping population of 122 recombinant inbred lines (RILs), derived from the cross of two black bean cultivars (' Puebla 152 ' and ' Zorro ') contrasting in SNF traits, was grown in the field in East Lansing, MI, and Isabela, Puerto Rico, and in the greenhouse under N-free conditions to evaluate for yield, nodule development, biomass growth, agronomic traits, and N fixation. The RIL population was also genotyped with single-nucleotide polymorphism (SNP) markers developed through the BeanCAP to construct a genetic map spanning 972 cM and containing 430 SNPs. A total of 17 unique QTL associated with SNF traits were identified with most of them located in three large clusters on Pv01 (4), Pv06 (6), and Pv08 (6). Many of the QTL associated with %N derived from atmosphere, N harvest index, and % N in biomass were also associated with candidate genes expressed in the nodules and roots. The majority of QTL associated with genes expressed in the root or nodule were derived from Puebla 152, while QTL associated with genes with enhanced expression in stems and pods were associated with Zorro. The QTL described should serve as potential targets for improvement of SNF characteristics in commercial dry bean genotypes adapted to temperate zones.

Populations' Response to Salinity Stress SO CROP SCIENCE LA English DT Article ID SALT-TOLERANT FORAGES; WATER REUSE SYSTEMS; ROOT-GROWTH; BIOMASS PRODUCTION; ION RELATIONS; SHOOT GROWTH; NITROGEN; NACL; ACCUMULATION; IRRIGATION AB Alfalfa (Medicago sativa L.) is a moderately salt-tolerant crop with high economic return and is therefore more suitable for production with lower quality water than most high-value crops. This study was conducted to examine the effect of water composition types (Cl- or SO42-) of irrigation water and five salinity levels (electrical conductivity of irrigation water [ECiw] = 0.85, 8, 13, 18.3, and 24.5 dS m(-1)) on biomass production, salt tolerance, and ion concentration of 15 alfalfa populations. The plants were grown in a greenhouse in 60 sand tanks for 347 d under salt treatment. There was no significant effect of water composition type on shoot and root biomass production. Water composition type x EC and water composition type x population interactions were also not significant. Salinity impact was population dependent (EC x population: P < 0.05), except at ECiw 18.3 dS m(-1). Across all populations, shoot biomass was significantly reduced with increasing salinity to 77, 50, and 27% of the control at 13, 18.3, and 24.5 dS m(-1), respectively. The 'SISA14' and 'SW 8421S' populations were the most productive under saline conditions with the highest degree of salt tolerance. The results showed that alfalfa biomass response to salinity did not depend on the type of salts (Cl- or SO42-). Shoot Cl- also did not correlate with relative biomass response. Thus, Cl- ion toxicity does not appear to be a factor in alfalfa salt tolerance for these populations. Although there was a correlation between salt tolerance and shoot Na+, the shoot ion concentration provides only a partial explanation of the relative salt tolerance of the alfalfa populations.

TI Measuring the Inefficiency of Allowing Self-Pollinated Alfalfa Progeny into Breeding Nurseries SO CROP SCIENCE LA English DT Article ID INBREEDING DEPRESSION; TETRAPLOID ALFALFA; FERTILITY AB Although alfalfa (Medicago sativa L.) is considered an outcrossing species, the self-pollination incidence during insect pollination can be substantial, with an observed 30% average selfing rate. Despite this, alfalfa breeders utilizing space-plant evaluation nurseries make no attempt to discriminate self-pollination-derived progeny (selfs) from outcross progeny. Due to alfalfa's substantial inbreeding depression, the selfed individuals have much lower breeder utility. This study examines an alfalfa space-plant breeding nursery in which selfed and outcross progeny had been identified using DNA markers for the following phenotypic traits: plant vigor, fall height, fall dormancy, first and second winter survival, plant lodging, and profusion of flowering. Trait means, phenotypic and additive variances, and narrow-sense heritabilities on a halfsib mean basis were determined for selfed and outcross progeny. For most traits, inbreeding depression was severe, with approximately 80% reductions in performance. Selfed progeny for most traits had reduced phenotypic variances compared with outcross progeny. No differences in estimated additive variance and heritabilities were observed between the two types of progeny. Assuming a 30% selfing rate and a selection intensity less than or equal to 10%, we would expect to select few if any selfed progeny from a space-plant nursery that had plant vigor phenotypic distributions observed in this study. The estimated maximum loss in genetic gain due to the presence of selfed progeny in breeding nurseries for selection intensities from 1 to 10% was estimated at a 10% genetic gain reduction. We conclude that selfed progeny in breeding nurseries are a hindrance, and if possible, they should be minimized or eliminated.

Determination of genetic variance for lint yield and fiber quality in three different crossing schemes (single cross [SC], three-way cross [TWC], and double cross [DC]) of upland cotton (Gossypium histutum L.) will help breeders decide which crossing scheme to use in hybrid production and pure-line development. This study was designed to compare agronomic performance and fiber quality among SCs, TWCs, and DCs and determine genetic variance for evaluated traits in the three crossing systems. A balanced set of 10 F-2 hybrid populations from each crossing system was planted with their five parents in 2013, 2014, and 2015. There were no significant differences for lint yield and fiber properties between SC and the other two crossing systems. When genetic variance components were expressed as proportions of the total phenotypic variances (V-P), there were mainly dominance (V-D) and environmental variances (V-E) for lint yield in F-2 hybrids of all three crossing systems. The predominance of V-D for lint yield suggests that selection would be more successful in later generations than in early generations among lines derived from SCs, TWCs, and DCs. The proportion of dominance (V-D/V-P) and additive genetic variances (V-A/V-P) for yield components was greater in TWCs and DCs than in SCs. Midparent heterosis (MPH) of lint yield in TWCs increased compared with SCs. Results indicate that TWCs may be used to enhance heterosis in hybrids, and TWCs and DCs may be used in pure-line development to increase yield potential of upland cotton cultivars.

Since 2003, a multi-environmental trial of public breeding maize (Zea mays L.) hybrids across multiple programs in the southeastern United States has evaluated accumulation of aflatoxin following inoculation with the fungus Aspergillus flavus Link. The Southeast Regional Aflatoxin Trial (SERAT) was formed to identify public germplasm with the most consistent resistance to aflatoxin accumulation and to evaluate their essential agronomic traits in different environments. Yield and related agronomic traits were evaluated in 13 locations; aflatoxin levels were evaluated in four. From 2006 to 2015, the 295 experimental hybrids, composed of varying percentages of tropical and subtropical germplasm, exhibited lower levels of aflatoxin on average at 323 versus 370 ng g-(1) for the commercial checks, while the check average of 10.1 Mg ha(-1) exceeded the research program average yield by 20%. Repeatability for log-transformed aflatoxin levels exceeded 0.50 in most years, while yield was mostly above 0.75. Testing for Type II stability indicated a positive response of high-yielding lines to better environments. The SERAT program enabled the identification of 13 top-performing experimental hybrids that have yielded on par with or exceeded check averages and had aflatoxin levels significantly lower than check averages.

Stepwise multiregression was used to determine which of the 20 composition traits had the largest significant effects on forage IVDMD and potential ethanol yield (ETOH) in a biorefinery. Switchgrass biomass samples from a field nursery containing the divergent switchgrass populations and families were harvested after flowering, dried, ground, and analyzed for composition traits by near-infrared reflectance analyses using previously developed near-infrared reflectance calibrations. After nonsignificant variables were eliminated, the resulting multiple regression models were highly significant (P < 0.001) and accounted for 95 and 96%, respectively, of the total variation for both IVDMD and ETOH. Standardized partial regression coefficients were used to estimate the relative importance of each significant variable. The biomass composition factors that had the largest impact on both IVDMD and ETOH were esterified ferulates, p-coumarate esters, specific cell wall sugars that are involved in the linkage of cell wall lignin to hemicellulose, N, and extracted fats. Klason lignin was not a significant variable in either regression analysis, even though it was strongly negatively correlated with both IVDMD and ETOH. The IVDMD test, which acted as a biological selection index in a longterm population breeding program, impacted an array of switchgrass biomass composition traits whose relative effects on both IVDMD and ETOH had not been previously quantified.

Liu, Shuyu TI Saturated Genetic Mapping of Wheat Streak Mosaic Virus Resistance Gene Wsm2 in Wheat SO CROP SCIENCE LA English DT Article ID FUSARIUM HEAD BLIGHT; TEMPERATURE-SENSITIVE RESISTANCE; RED WINTER-WHEAT; FIELD CONDITIONS; STRIPE RUST; LEAF RUST; REGISTRATION; MARKERS; IDENTIFICATION; INHERITANCE AB In the U.S. Great Plains and other parts of the world, Wheat streak mosaic virus (WSMV) disease is one of the most important biotic stresses affecting wheat (Triticum aestivum L.) productivity. Breeding for wheat cultivars with resistance provides a socioeconomic and environmentally sustainable approach for combating WSMV. The use of markers as a proxy for quantitative and qualitative traits is widely applied in crop improvement programs. Among the available markers, single nucleotide polymorphisms (SNPs) are routinely used in plant breeding programs to distinguish potentially superior genotypes with genetic merit for traits of interest. In this study, we used the 90K Illumina Infinium iSelect SNP assay to tag the Wsm2 gene in a set of 152 recombinant inbred lines (RILs) derived from the cross between CO960293-2 and TAM 111. The RILs were evaluated twice for WSMV resistance in the growth chambers. A dense linkage map with coverage of 2079.5 cM was constructed. The Wsm2 gene was mapped on chromosome 3BS. A total of eight SNPs flanking Wsm2 were mapped within 1.0 cM. These tightly linked SNPs could be useful for marker-assisted selection for WSMV resistance.

A recently identified WSMV resistance gene, Wsm2, was mapped to chromosome 3BS in germplasm line 'CO960293-2'. Effective genetic markers tightly linked to the gene will enhance the selection of WSMV-resistant lines through marker-assisted selection. We have mapped Wsm2 using a high-density map developed from the wheat 90K Infinium iSelect single-nucleotide polymorphism (SNP) array with recombinant inbred lines from the cross between CO960293-2 and susceptible cultivar 'TAM 111'. Array-based SNPs that mapped within 4 cM of Wsm2 on chromosome 3BS were converted to Kompetitive Allele Specific Polymerase Chain Reaction (KASP) assays in this study. Six KASP SNPs were validated in two doubled haploid populations developed from crosses of 'RonL' x 'Ripper' and 'Snowmass' x 'Antero'. RonL and Snowmass possess the Wsm2 gene from CO960293-2. Three closely linked KASP SNPs, converted from IAAV6442, BS00018764_51, and wsnp_Ra_ c16264_24873670, showed high sensitivity and specificity (0.83 <= sensitivity <= 0.97, 0.89 <= specificity <= 0.99). The latter two were also validated in six F-2 breeding populations. These three KASP SNPs were effective in differentiating resistant and susceptible genotypes. Comparative mapping was performed using sequences of SNPs flanking Wsm2 and identified candidate genes and regions in Brachypodium and rice (Oryza sativa L. ssp. japonica). The KASP SNPs developed in this study should be useful for marker-assisted selection of Wsm2 in wheat breeding programs, and the newly constructed map will also facilitate map based cloning of Wsm2.

TI Early Seedling Growth Characteristics Relate to the Staygreen Trait and Dhurrin Levels in Sorghum SO CROP SCIENCE LA English DT Article ID STAY-GREEN; CYANOGENIC GLUCOSIDES; PLANTS; BIOSYNTHESIS; METABOLISM; ENVIRONMENTS; TRANSPORT; TURNOVER; NITROGEN; HYBRIDS AB Dhurrin content in leaves of the mature sorghum [ Sorghum bicolor (L.) Moench] plant is a quantitative measure of the level of pre- and postflowering drought tolerance, with high dhurrin contents expressed in postflowering drought-tolerant lines. Postflowering drought tolerance in sorghum has been linked to the staygreen trait and associated with increased grain yield during postanthesis stress. Seasonal variability in postflowering drought occurrences makes selection for the staygreen trait unpredictable and the efficiency and reliability of screening for the trait using only conventional breeding low. Differences in dhurrin content between high and low dhurrin levels lines is only markedly favored to the high dhurrin level lines in the upper leaves of matured field-grown plants. Here we report a screening method using early seedling growth characteristics of sorghum lines of known dhurrin level grown in sand with no inorganic nutrients supply. The method was evaluated under cold and warm temperatures. Seedling growth characteristics and contents of dhurrin and high-performance liquid chromatography-detected sugars were determined at 5, 10, 17, and 23 d after emergence. High dhurrin level lines had larger increases in shoot fresh weight, dried weight, and length than did lines with low dhurrin levels at 10 d after emergence under both temperatures. Similar trends were observed when separating lines into high and low dhurrin levels using fresh shoot mass and length at 10 d after emergence. Dhurrin content decreased with seedling age, was statistically similar between dhurrin levels, and negatively correlated to concentrations of sugar. Thus, selecting for postflowering drought tolerance can be timely, reliably, and inexpensively done using early seedling growth characteristics.

Schwartz, Robert C. TI Do More Seeds per Panicle Improve Grain Sorghum Yield? SO CROP SCIENCE LA English DT Article ID BICOLOR L-MOENCH; DROUGHT STRESS; WATER-USE; ENVIRONMENT; GROWTH; WEIGHT; NUMBER; SIZE AB Seed number, rather than seed mass, is largely considered to be the most important yield component of grain sorghum [Sorghum bicolor (L.) Moench]. An experimental sorghum mutant line with enhanced seed number (tri-seed) was grown at the Soil-Plant-Environment Research (SPER) facility, USDA-ARS, Bushland, TX, in 2014 and 2015 to provide field validation of the tri-seed line's ability to increase yield. The SPER facility had a rain shelter to control the soilwater balance. The parent inbred line BTx623 and the tri-seed line MSD-P5, which originated as a mutant of BTx623, were grown in weighing lysimeters with undisturbed soil profiles of four agriculturally productive soils (Pullman clay loam, Ulysses silt loam, Amarillo sandy loam, and Vingo fine sand) of the US Great Plains. Planting density was 16 plants m(-2) and the crops received either 18 or 36 mm of irrigation weekly. The triseed line produced significantly smaller grain yield, seed mass, and total biomass compared with the parent line. The mass per panicle was similar between lines, but a significantly larger proportion of the tri-seed line panicle was nongrain panicle mass compared with the parent line. Both hybrids exhibited some plasticity in seed mass to accommodate assimilate as it became available, but increased seed mass, along with increased seed number, also did not result in a significant increase in harvest index for the tri-seed line compared with the parent line. The increase in seed number by the tri-seed line did not compensate for the decreased seed mass, which consequently failed to increase grain yield or harvest index.

TI Biochanin A (an Isoflavone Produced by Red Clover) Promotes Weight Gain of Steers Grazed in Mixed Grass Pastures and Fed Dried-Distillers' Grains SO CROP SCIENCE LA English DT Article ID AMMONIA-PRODUCING BACTERIUM; TALL FESCUE PASTURE; DAIRY-COWS; CLOSTRIDIUM-STICKLANDII; RUMINAL FERMENTATION; AMINO-ACIDS; RUMEN; PROTEIN; PERFORMANCE; METABOLISM AB Biochanin A (BCA) is an isoflavone produced by red clover (Trifloium pratense L.) that can inhibit hyper-ammonia-producing bacteria (HAB) to reduce deamination in the rumen and increase the feed amino acids available for gastric digestion. An ex vivo experiment was conducted to evaluate the effect of dried distiller's grains (DDG) and BCA (30 mg mL(-1)) on HAB in bovine rumen fluid. Following a 24-h incubation, HAB and ammonia concentrations in the media increased with addition of DDG. However, DDG fermentations with BCA had 100-fold fewer HAB and 37% less ammonia than DDG-only fermentations. A grazing experiment was conducted with crossbred steers grazing a mixture of predominately endophyte-free tall fescue [Lolium arundinaceum (Schreb.) Darbysh], Kentucky bluegrass (Poa pratense L.), and orchardgrass (Dactylis glomerata L.) in the early and late growing season. Average daily gains (ADG) were compared among treatments of pasture-only control, daily feeding of 1.4 kg DDG steer(-1), and daily feeding of 1.4 kg DDG plus BCA (6.3 g steer(-1), representing similar to 30% red clover diet). Averaged over the early and late growing seasons, feeding DDG (0.83 +/- 0.05 kg d-1) increased ADG by 15% over the pastureonly treatment (0.72 +/- 0.03 kg d(-1)), but addition of BCA to the DDG (0.93 +/- 0.04 kg d(-1)) provided an additive increase in ADG of 29% over the control treatment. Results of the ex vivo and grazing experiments provide evidence that BCA inhibits HAB in the rumen and that the reduced deamination in the rumen can enhance weight gain performance of steers.

TI Season Progression, Ontogenesis, and Environment Affect Lespedeza cuneata Herbage Condensed Tannin, Fiber, and Crude Protein Concentrations SO CROP SCIENCE LA English DT Article ID GASTROINTESTINAL NEMATODE INFECTION; SERICEA-LESPEDEZA; NUTRITIVE-VALUE; ILLINOIS BUNDLEFLOWER; LOTUS-PEDUNCULATUS; FORAGE QUALITY; RHIZOMA PEANUT; DRYING METHOD; LEAF MEAL; GOATS AB Sericea lespedeza [Lespedeza cuneata (Dumont de Courset) G. Don., SL] is a perennial, warm-season forage legume with wide adaptation, freeze tolerance, establishment ease, and persistence under grazing. It has high condensed tannin (CT) concentrations (g kg(-1)), which could be useful for methane mitigation and rumen bypass protein, as well as insect pest and gastro-intestinal nematode suppression. However, CT concentration is variable. Our objective was to test CT, crude protein (CP), and fiber concentrations at five locations (Georgia, Alabama, North Carolina, Louisiana, and Texas) during a growing season. Established 'AU Grazer' SL regrowth and accumulated herbage in separate trials was sampled starting late April 2010 every 35 d for four dates. Regrowth CP concentration ranged (P <= 0.05) from 127 g kg(-1) in North Carolina on date 3 up to 221 g kg-1 in Alabama on date 1. Sericea lespedeza regrowth in the warmest latitude (Louisiana) consistently contained among the greatest (P <= 0.05) acid detergent fiber. In regrowth herbage, we recorded a wide (P <= 0.05) total CT range, from 133.5 mg kg(-1) in Texas on date 3 to 46.1 mg kg(-1) in Louisiana on date 1, reflecting variability in fiber-bound, protein-bound, and especially extractible CT. Results from accumulated herbage reflected (P <= 0.05) herbage ontogenesis with less CP and greater fiber concentration with maturity but showed the same lack of CT concentration pattern as the regrowth herbage. These results indicate that SL herbage nutritive value and CT concentration is variable, so that any hay or pellets sold commercially for CT content should be assayed by environment and crop maturity.

Understanding the mechanisms underlying successful invasions is an important component of conservation and management efforts, but this has been poorly investigated in a spatially explicit manner. Knowing where and why invasion patterns change throughout the landscape enables managers to use context-specific controls on the spread of invasive species. Using high-resolution airborne imaging spectroscopy, we studied plant performance in growth within and across landscapes to examine the dominance and spatial distribution of an invasive tree, Psidium cattleianum (strawberry guava), in heterogeneous environmental conditions of a submontane Hawaiian tropical forest. We assessed invader performance using the GPP ratio index, which is the relative difference in remotely sensed estimates of gross primary productivity between canopies of guava and canopies of the invaded plant community. In addition, we used airborne LiDAR data to evaluate the impacts of guava invasion on the forest aboveground carbon density in different environments. Structural equation modeling revealed that substrate type and elevation above sea level interact and amplify landscape-scale differences in productivity between the invasive species and the host plant community (GPP ratio); differences that ultimately control levels of dominance of guava. We found shifts in patterns of forest carbon storage based on both gradual increase of invader dominance and changes in environmental conditions. Overall, our results demonstrate that the remotely sensed index defined as the GPP ratio provided an innovative spatially explicit approach to track and predict the success of invasive plants based in their canopy productivity, particularly within a landscape-scale framework of varying environmental factors such as soils and elevation. This approach may help managers accurately predict where invaders of forests, scrublands, or grasslands are likely to exhibit high levels of dominance before the environment is fully invaded.

We used a probabilistic framework of wildfire occurrence to (1) estimate the potential for fuel treatments to reduce fire risk and hazard across the landscape and within protected California spotted owl (Strix occidentalis occidentalis) habitat and (2) evaluate the consequences of treatments with respect to terrestrial C stocks and burning emissions. Silvicultural and prescribed fire treatments were simulated on 20% of a northern Sierra Nevada landscape in three treatment scenarios that varied in the land area eligible for treatment. Treatment prescriptions varied with topography, vegetation characteristics, and ownership. We then simulated many wildfires in the treated and untreated landscapes. Additional simulations allowed us to consider the influence of wildfire size on estimated emissions. Treatments constrained to the land area outside of spotted owl activity centers reduced the probability of burning and potential fire intensity within owl habitat and across the landscape relative to no-treatment scenarios. Allowing treatment of the activity centers achieved even greater fire hazard reductions within the activity centers. Treatments also reduced estimated wildfire emissions of C by 45-61%. However, emissions from prescribed burning exceeded simulated reductions in wildfire emissions. Consequently, all treatment scenarios resulted in higher C emissions than the no-treatment scenarios. Further, for wildfires of moderate size (714-2133 ha), the treatment scenarios reduced the C contained in live tree biomass following simulated wildfire. When large wildfires (8070-10,757 ha) were simulated, however, the treatment scenario retained more live tree C than the no-treatment scenario. Our approach, which estimated terrestrial C immediately following wildfire, did not account for long-term C dynamics, such as emissions associated with post-wildfire decay, C sequestration by future forest growth, or longer-term C sequestration in structural wood products. While simulated landscape fuel treatments in the present study reduced the risk of uncharacteristically severe wildfire across the landscape and within protected habitat, the C costs of treatment generally exceeded the C benefits.

We simulated potential changes to fire dynamics and forest characteristics under three future climate projections representing a range of potential future conditions using the FireBGCv2 model. Under the future climate scenarios with moderate warming (>2 degrees C) and moderate increases in precipitation (3-5%), model simulations resulted in 1.2-4.2 times more burned area, decreases in forest cover (10-44%), and reductions in basal area (14-60%). In these same scenarios, lodgepole pine (Pinus contorta) decreased in basal area (18-41%), while Douglasfir (Pseudotsuga menziesii) basal area increased (21-58%). Conversely, mild warming (< 2 degrees C) coupled with greater increases in precipitation (12-13%) suggested an increase in forest cover and basal area by mid-century, with spruce and subalpine fir increasing in abundance. Overall, we found changes in forest tree species compositions were caused by the climate-mediated changes in fire regime (56-315% increase in annual area burned). Simulated changes in forest composition and fire regime under warming climates portray a landscape that shifts from lodgepole pine to Douglas-fir caused by the interaction between the magnitude and seasonality of future climate changes, by climate-induced changes in the frequency and intensity of wildfires, and by tree species response.

Red imported fire ants are implicated in the decline of native invertebrates and vertebrates throughout their invaded range. We used the eastern fence lizard (Sceloporus undulatus) as a model species to understand the influence of RIFAs on native reptiles in the southeastern United States. Our objective was to quantify the effects of RIFAs on fence lizard recruitment and survival. We experimentally stocked populations of fence lizards into eight enclosures with either ambient or reduced numbers of RIFAs from May 2012 to October 2013. Fitting Link-Barker models, we found that the RIFA treatment affected fence lizard recruitment (f), but not survival (F). Recruitment was 1.6 times greater in the enclosures with reduced numbers of RIFAs than in those with ambient numbers. Red imported fire ants likely affect reptiles with analogous life history strategies to those of fence lizards similarly. Consequently, RIFAs may have undesirable consequences for the biodiversity of reptiles in the southeastern United States and on other continents with established RIFA populations.

This study was established in 2000 to assess regeneration following prescribed fire (spring of 2001, 2005, and 2010) in combination with partial harvest (late 2000) across two sites in southern Ohio. Each of the four 20+ ha treatment units (two partial harvest and burn, two controls) were modeled and mapped for long-term moisture regime using the Integrated Moisture Index (IMI), and a 50-m grid of sampling points established throughout the units. Vegetation and light were sampled at each gridpoint before and after treatments, in 2000, 2001, 2004, 2006, 2009, and 2013. The partial harvest and burn treatments generally had more light which resulted in an increased number of oak stems. The fires promoted heterogeneity (pyrodiversity) in tree mortality and light availability, and consequently oak-hickory regeneration, mostly following IMI patterns with the drier portions of the landscape having more fire, more light penetration, and greater regeneration compared to moist locations. Several other species also had marked variations in numbers and size throughout this period, depending on landscape variation in fire intensity and moisture regimes. These included Acer rubrum and Liriodendron tulipifera which expanded initially then collapsed after repeated fire, and Sassafras albidum which continued to flourish on dry sites. Based on this study, we recommend for topographically appropriate dry and intermediate sites, a partial harvest followed by two or three dormant-season fires (depending on fire intensity) allowing roughly 6-18% light to penetrate the forest floor. This will promote oak-hickory into the advanced oak regeneration status. Then, following a hiatus from burning for some years to further advance oak-hickory growth without topkill, some proportion of oaks and hickories can be expected to advance to the canopy following natural disturbance or harvest of current canopy. On mesic sites, though treatments demonstrated here do improve oak-hickory regeneration, the relative cost to benefit would be high.

This changing fire regime, coupled with increased high-severity fire risk from a legacy of fire exclusion, could destabilize forest carbon (C), decrease net ecosystem exchange (NEE), and consequently reduce the ability of forests to regulate climate through C sequestration. While management options for minimizing the risk of high-severity fire exist, little is known about the longer-term carbon consequences of these actions in the context of continued extreme fire weather events. Our goal was to compare the impacts of extreme wildfire events on carbon stocks and fluxes in a watershed in the Sierra National Forest. We ran simulations to model wildfire under contemporary and extreme fire weather conditions, and test how three management scenarios (no-management, thin-only, thin and maintenance burning) influence fire severity, forest C stocks and fluxes, and wildfire C emissions. We found that the effects of treatment on wildfire under contemporary fire weather were minimal, and management conferred neither significant reduction in fire severity nor increases in C stocks. However, under extreme fire weather, the thin and maintenance burning scenario decreased mean fire severity by 25%, showed significantly greater C stability, and unlike the no-management and thin-only management options, the thin and maintenance burning scenario showed no decrease in NEE relative to the contemporary fire weather scenarios. Further, under extreme fire weather conditions, wildfire C emissions were lowest in the thin and maintenance burning scenario, (reduction of 13.7 Mg C/ha over the simulation period) even when taking into account the C costs associated with prescribed burning. Including prescribed burning in thinning operations may be critical to maintaining C stocks and reducing C emissions in the future where extreme fire weather events are more frequent.

The increased proportion of WWF in blends raised mixograph absorption with insignificant changes in protein content and dough strength-related parameters. WWF incorporation generally increased specific volume and crumb softness of CSB. The analysis of covariance revealed that CSB quality attributes were little affected by protein content and dough strength-related parameters, indicating that starch amylose content was largely responsible for the changes in CSB quality. Flour blends with 5-10% WWF, of which starch amylose content was 22.4-24.7%, produced CSB with superior crumb structure compared to other blends, but insignificant changes in surface smoothness, stress relaxation and total score compared to the respective control wheat flours. Flour blends with 15% WWF to prothfce a starch amylose content of 21.4-22.7% exhibited reduced staling of CSB with total scores comparable to the respective control wheat flours. CSB prepared from blends with more than 10% WWF exhibited a higher soluble starch content, indicative of reduced starch retrogradation, than that prepared from wheat flours without WWF during storage for 3 days.

Absence of the Glu-B3 LMW-GS proteins was determined by one-dimensional gel electrophoresis (SDS-PAGE) and confirmed by two-dimensional gel electrophoresis (2-DGE) and tandem mass spectrometry (MS/MS). The deletion of Glu-B3 genes was also demonstrated using allele specific DNA markers. Basic agronomic traits, protein content, dough mixing properties and bread loaf volume of DH2O and parental wheat cultivars were evaluated in field-grown wheat over a two year period. This mutant is a valuable resource for understanding the function of individual LMW-GS alleles or genes at the Glu-B3 locus using either breeding or biotechnology approaches. (C) 2017 Elsevier Ltd.

We also examined surface gene reassortant viruses composed of the haemagglutinin and neuraminidase from A/Iraq/755/06 and the internal genes of a 2009 pandemic H1N1 virus, A/New York/18/2009 (2Iraq/06 : 6NY/09 H5N1), and haemagglutinin and neuraminidase from A/New York/18/2009 with the internal genes of A/Iraq/755/06 (2NY/09 : 6Iraq/06 H1N1). The parental A/Iraq/755/06 caused little to no lesions in swine, limited virus replication was observed in the upper respiratory and lower respiratory tracts and transmission was detected in 3/5 direct-contact pigs based on seroconversion, detection of viral RNA or virus isolation. In contrast, the 2Iraq/06 : 6NY/09 H5N1 reassortant caused mild lung lesions, demonstrated sustained virus replication in the upper and lower respiratory tracts and transmitted to all contacts (5/5). The 2NY/09 : 6Iraq/06 H1N1 reassortant also caused mild lung lesions, there was evidence of virus replication in the upper respiratory and lower respiratory tracts and transmission was detected in all contacts (5/5). These studies indicate that an HPAI-derived H5N1 reassortant with pandemic internal genes may be more successful in sustaining infection in swine and that HPAI-derived internal genes were marginally compatible with pandemic 2009 H1N1 surface genes. Comprehensive surveillance in swine is critical to identify a possible emerging HPAI reassortant in all regions with HPAI in wild birds and poultry and H1N1pdm09 in pigs or other susceptible hosts.

Severe combined immunodeficiency (SCID) is a condition characterized by a deficiency of T, B, and/or natural killer (NK) cells. Animal models of SCID have great value for biomedical research. Here, we evaluated the pathogenesis and the innate immune response to the 2009 H1N1 pandemic IAV (H1N1pdm09) using a recently identified line of naturally occurring SCID pigs deficient in T and B lymphocytes that still have functional NK cells. SCID pigs challenged with H1N1pdm09 showed milder lung pathology compared to the non-SCID heterozygous carrier pigs. Viral titers in the lungs and nasal swabs of challenged SCID pigs were significantly higher than in carrier pigs 7 days postinfection, despite higher levels of IL-1 beta and IFN-alpha in the lungs of SCID pigs. The lower levels of pulmonary pathology were associated with the T and B cell absence in response to infection. The higher viral titers, prolonged shedding, and delayed viral clearance indicated that innate immunity was insufficient for controlling IAV in pigs. This recently identified line of SCID pigs provides a valuable model to understand the immune mechanisms associated with influenza protection and recovery in a natural host. (C) 2016 S.

TI Succession, climate and neighbourhood dynamics influence tree growth over time: an 87-year record of change in a Pinus resinosa-dominated forest, Minnesota, USA SO JOURNAL OF VEGETATION SCIENCE LA English DT Article DE Climate; Competition; Crowding; Demographic transition; Jack pine; Pinus banksiana; Pinus resinosa; Red pine; Stand dynamics ID OLD-GROWTH; ASYMMETRIC COMPETITION; PLANT COMPETITION; SIZE ASYMMETRY; RADIAL-GROWTH; STANDS; MODELS; COMMUNITIES; HYPOTHESIS; GRADIENT AB QuestionResource availability and its influence on tree-to-tree interactions are expected to change over the course of forest stand development, but the rarity of long-term data sets has limited examinations of neighbourhood crowding over extended time periods. How do a history of neighbourhood interactions and population-level dynamics, including demographic transition, impact long-term tree growth? LocationNatural mature Pinus resinosa-dominated forest in northern Minnesota, USA. MethodsUsing a spatially explicit data set of repeated diameter measurements recorded over an 87-yr period, we modelled the influence of tree-to-tree interactions on growth as it varied over time. We also applied maximum likelihood estimation and simulated annealing to examine how inter- and intraspecific competition and the relative importance of neighbour size and distance varied over time and with different climatic conditions. ResultsCrowding had a consistent negative influence on growth, but crowding intensity and importance were dynamic over time and differed between trees that survived the entire study period compared to those that ultimately died. The scaling of neighbour diameter, neighbour distance, and neighbour species (inter- vs intraspecific competition) also varied as demographic transition occurred and longer-lived species assumed greater dominance. ConclusionsGiven observed relationships with moisture stress (based on precipitation: potential evapotranspiration) and maximum temperature, crowding intensity and importance may increase if temperatures rise in the future and water become more limiting. Long-term data sets, such as the record examined in this study, have immense value for testing assumptions about stand dynamics, particularly as forests respond to projected shifts in climate and disturbance regimes.

TI New Pesticidal Diterpenoids from Vellozia gigantea (Velloziaceae), an Endemic Neotropical Plant Living in the Endangered Brazilian Biome Rupestrian Grasslands SO MOLECULES LA English DT Article DE diterpene; herbicide; natural products; Velloziacea AB Vellozia gigantea is a rare, ancient, and endemic neotropical plant present in the Brazilian Rupestrian grasslands. The dichloromethane extract of V. gigantea adventitious roots was phytotoxic against Lactuca sativa, Agrostis stolonifera, and Lemna paucicostata, and showed larvicidal activity against Aedes aegypti. Phytotoxicity bioassay-directed fractionation of the extract revealed one new isopimaradiene, 8(9),15-isopimaradien-1,3,7,11-tetraone, and three new cleistanthane diterpenoids, 7-oxo-8,11,13-cleistanthatrien-3-ol, 3,20-epoxy-7-oxo-8,11,13-cleistanthatrien-3-ol, and 20-nor-3,7-dioxo-1,8,11,13-cleistanthatetraen-10-ol. These new structures are proposed based on interpretation of H-1, C-13, COSY, NOESY, HSQC, and HMBC NMR data. 8(9),15-isopimaradien-1,3,7,11-tetraone was especially phytotoxic with an IC50 value (30 M) comparable to those of commercial herbicides clomazone, EPTC, and naptalam. In addition, 7-oxo-8,11,13-cleistanthatrien-3-ol provided 100% mortality at a concentration of 125 ppm against one-day-old Ae. aegypti larvae. Our results show that ancient and unique plants, like the endangered narrowly endemic neotropical species V. gigantea present in the Rupestrian grasslands, should also be protected because they can be sources of new bioactive compounds.

However, its bioaccumulation pattern during early development is not understood. In this pilot study, we investigated whether carotenoid supplementation of infant formula enhanced lutein tissue deposition in infant rhesus macaques. Monkeys were initially breastfed; from 1 to 3 months of age they were fed either a formula supplemented with lutein, zeaxanthin, beta-carotene and lycopene, or a control formula with low levels of these carotenoids, for 4 months (n = 2/group). All samples were analyzed by high pressure liquid chromatography (HPLC). Final serum lutein in the supplemented group was 5 times higher than in the unsupplemented group. All brain regions examined showed a selective increase in lutein deposition in the supplemented infants. Lutein differentially accumulated across brain regions, with highest amounts in occipital cortex in both groups. beta-carotene accumulated, but zeaxanthin and lycopene were undetectable in any brain region. Supplemented infants had higher lutein concentrations in peripheral retina but not in macular retina. Among adipose sites, abdominal subcutaneous adipose tissue exhibited the highest lutein level and was 3-fold higher in the supplemented infants. The supplemented formula enhanced carotenoid deposition in several other tissues. In rhesus infants, increased intake of carotenoids from formula enhanced their deposition in serum and numerous tissues and selectively increased lutein in multiple brain regions.

However, the mechanistic action of butyrate remains to be determined. We hypothesize that butyrate inhibits cancerous cell proliferation but to a lesser extent in noncancerous cells through regulating apoptosis and cellular-signaling pathways. We tested this hypothesis by exposing cancerous HCT116 or non-cancerous NCM460 colon cells to physiologically relevant doses of butyrate. Cellular responses to butyrate were characterized by Western analysis, fluorescent microscopy, acetylation, and DNA fragmentation analyses. Butyrate inhibited cell proliferation, and led to an induction of apoptosis, genomic DNA fragmentation in HCT116 cells, but to a lesser extent in NCM460 cells. Although butyrate increased H3 histone deacetylation and p21 tumor suppressor expression in both cell types, p21 protein level was greater with intense expression around the nuclei in HCT116 cells when compared with that in NCM460 cells. Furthermore, butyrate treatment increased the phosphorylation of extracellular-regulated kinase 1/2 (p-ERK1/2), a survival signal, in NCM460 cells while it decreased p-ERK1/2 in HCT116 cells. Taken together, the activation of survival signaling in NCM460 cells and apoptotic potential in HCT116 cells may confer the increased sensitivity of cancerous colon cells to butyrate in comparison with noncancerous colon cells.

Due to the small sizes and rapid water dynamics, monitoring the extent of small lakes fluctuating between 2.5 and 30 km(2) require observations with both high spatial and temporal resolutions. The paper applied an improved surface reflectance (SR) downscaling method (i.e., IMAR (Improved Modified Adaptive Regression model)) to downscale the daily SR acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) Terra platform to a consistent 250-m resolution, and derived monthly water extent of four small lakes in the Tibetan Plateau (Longre Co, Ayonggongma Co, Ayonggama Co, and Ayongwama Co)) from 2000 to 2014. Using Landsat ETM+ acquired on the same date, the downscaled MODIS SR and identified water extent were compared to the original MODIS, observations downscaled using an early SR downscaling method (MAR (Modified Adaptive Regression model)) and Wavelet fusion. The results showed IMAR achieved the highest correlation coefficients (R-2) (0.89-0.957 for SR and 0.79-0.933 for water extent). The errors in the derived water extents were significantly decreased comparing to the results of MAR and Wavelet fusion, and lakes morphometry of IMAR is more comparable to Landsat results. The detected lake extents dynamic between 2000 and 2014 were analyzed using the trend and season decomposition model (BFAST), indicating an increasing trend after 2005, and it likely had higher correlations with temperature and precipitation variation in the Tibetan region (R-2: 0.598-0.728 and 0.61-0.735, respectively).

However, the underlying methods to monitor phenological events often limit this understanding. Generally, one can either have a small sample of in situ measurements or use satellite data to observe large areas of land surface phenology (LSP). In the latter, a tradeoff exists among platforms with some allowing better temporal resolution to pick up discrete events and others possessing the spatial resolution appropriate for observing heterogeneous landscapes, such as urban areas. To overcome these limitations, we applied the Spatial and Temporal Adaptive Reflectance Model (STARFM) to fuse Landsat surface reflectance and MODIS nadir BRDF-adjusted reflectance (NBAR) data with three separate selection conditions for input data across two versions of the software. From the fused images, we derived a time-series of high temporal and high spatial resolution synthetic Normalized Difference Vegetation Index (NDVI) imagery to identify the dates of the start of the growing season (SOS), end of the season (EOS), and the length of the season (LOS). The results were compared between the urban and exurban developed areas within the vicinity of Ogden, UT and across all three data scenarios. The results generally show an earlier urban SOS, later urban EOS, and longer urban LOS, with variation across the results suggesting that phenological parameters are sensitive to input changes. Although there was strong evidence that STARFM has the potential to produce images capable of capturing the UHI effect on phenology, we recommend that future work refine the proposed methods and compare the results against ground events.

The main factors taken into consideration for this assessment included the total number of animals at risk, potential detrimental effects of parasitism on milk production or weight gain, and records of condemnation on livestock byproducts. Estimates in US dollars (US$) were based on reported yield losses in untreated animals. These estimates reflect the major effects on cattle productivity of six parasites, or parasite group. The potential economic impact (US$ millions) was: gastrointestinal nematodes US$ 445.10; coccidia (Eimeria spp.) US$ 23.78; liver fluke (Fasciola hepatica) US$ 130.91; cattle tick (Rhipicephalus microplus) US$ 573.61; horn fly (Haematobia irritans) US$ 231.67; and stable fly (Stomoxys calcitrans) US$ 6.79. Overall, the yearly economic loss due to the six major parasites of cattle in Mexico was estimated to be US$ 1.41 billion. Considering that the national cattle herd registered in 2013 included 32.40 million head, the estimated yearly loss per head was US$ 43.57. The limitations of some of the baseline studies used to develop these estimates, particularly when extrapolated from local situations to a national scale, are acknowledged. However, the general picture obtained from the present effort demonstrates the magnitude and importance of cattle parasitism in Mexico and the challenges to maximize profitability by the livestock industry without adapting sustainable and integrated parasite control strategies. irritans) C1 [Ivan Rodriguez-Vivas, Roger; de Jesus Torres-Acosta, Juan Felipe] Univ Autonoma Yucatan, Fac Med Vet & Zootecnia, Campus Ciencias Biol & Agr, Merida 97100, Yucatan, Mexico.

Here, we fabricated Au@ Ag NPs with tailored shell thickness, and investigated their antibacterial activities against both Gram-negative bacteria (Escherichia coli) and Gram-positive bacteria (Staphylococcus aureus) and the cytotoxicity toward SH-SY5Y human cells, for the first time. Our results demonstrate that Au@ Ag NPs with a thickness of 5 nm or Au : Ag ratio 1 : 1 (Au@ Ag-2 NPs) have the highest antibacterial activity and excellent biocompatibility. The minimum inhibitory concentration (MIC) values of Au@ Ag-2 NPs in terms of effective silver concentration are 5 mg mu L-1 for E. coli and 7.5 mg mu L (-1) for S. aureus, which is significant lower than that of Ag NPs or the simple mixture of Ag and Au NPs and suggests the synergistic effects of Au and Ag in core-shell NPs. Live/dead bacterial assay and scanning electron microscope (SEM) images demonstrated that the Au@ Ag NPs disrupt the bacterial cell membrane which subsequently results in cellular material leakage and cell death. The Au@ Ag NPs may have great potential as effective antibacterial agents for pathogen control in hospitals and food processing.

TI Water Retention and Preferential States of Soil Moisture in a Cultivated Vertisol SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID PORE-SIZE DISTRIBUTION; HYDRAULIC-PROPERTIES; FIELD-SCALE; CLAY; DISTRIBUTIONS; CONDUCTIVITY; POTENTIALS; DRYNESS; CURVES; IMPACT AB Vertisols are well suited for rainfed agriculture in water-limited environments as a result of their unique water transfer and retention characteristics. Despite their importance, the agro-hydrological behavior of these soils under seasonally dry climates is not yet fully understood. We collected water retention data for a Vertisol, measured from saturation to oven dryness on 27 undisturbed topsoil (0-0.05 m) samples from an experimental field in southcentral Spain and related this information to the occurrence of field-observed preferential soil moisture states. A continuous function was fitted to the mean gravimetric water retention data, circle minus, consisting of the sum of a double exponential model and the Groenevelt and Grant model. An inflection point at pressure head |h| = 1.1 X 10(5) cm, circle minus = 0.12 kg kg(- 1), and an equivalent pore radius, delta = 14 nm, was interpreted as the boundary between the clay inter-and intra-aggregate pore spaces, corresponding with the transition from the intermediate to the dry field soil moisture state. The mode of the textural pore space (|h| = 7.3 X 10(3) cm, circle minus = 0.21 kg kg(- 1), and delta = 200 nm) matched the transition from the wet to the intermediate field soil moisture state. We related these characteristics of the soil water retention curve with the spatiotemporal soil moisture dynamics and patterns observed in the field, characterized by fast transitions between preferential soil moisture states. The proposed framework is suitable for comparing the effects of different soil management strategies on the agro-hydrological performance of Vertisols.

TI Diversified No-Till Crop Rotation Reduces Nitrous Oxide Emissions, Increases Soybean Yields, and Promotes Soil Carbon Accrual SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID ORGANIC-MATTER; CONTRASTING MANAGEMENT; CORN-BELT; SYSTEMS; SEQUESTRATION; QUALITY; FLUXES AB The effect of crop rotational diversity on greenhouse gas (GHG) emissions has been explored in several studies, although rarely have measurements been made on whole rotations consisting of two or more crops. We evaluated the impact of crop rotational diversity on GHG emissions, soil organic carbon (SOC), and crop yields over a 4-yr period in eastern South Dakota, USA. Under no-till, rain-fed conditions, a 2-yr (corn [Zea mays L.]-soybean [Glycine max (L.) Merr.]) rotation and a 4-yr rotation (corn-field peas [Pisum sativum L.]-winter wheat [Triticum aestivum L.]-soybean) were established in a randomized, complete block design (each crop present each year) 8 yr prior to the current study. Average daily N2O fluxes were 24% lower (P = 0.0313) for the 4-yr rotation (2.34 +/- 0.56 g N2O-N ha(-1)d(-1)) compared with the 2-yr rotation (3.06 +/- 0.59 g N2O-N ha(-1)d(-1)). Significantly elevated N2O flux peaks were observed in June of every year and every phase of the 2-yr rotation, but only in one of 4 yr (corn phase) in the 4-yr rotation. There was no significant difference in average daily CH4 flux between the two rotations. Over this 4-yr period, SOC increased in the 0- to 15-cm depth interval for the 2-yr rotation, but increased in both the 0-to 15- and 15- to 30- cm depth intervals for the 4-yr rotation. Corn yields (6.75 Mg ha(-1)) did not differ between the two rotations. However, the yield of soybean in the 4-yr rotation (2.87 Mg ha(-1)) was 22% greater (P = 0.0001) than soybean within the 2-yr rotation (2.35 Mg ha(-1)). Diversified rotations can decrease N2O emissions, increase or accelerate SOC gains, distribute soil C gains deeper in the soil profile, and boost soybean yield. C1 [Lehman, R.

These commercial vineyards exist on three soil series (Redding, San Joaquin, and Tokay), representing a spectrum of soil textures and degrees of soil development. We hypothesized that soil characteristics would be a dominating factor affecting GHG fluxes, but the magnitude of fluxes would be influenced by precipitation and management events. We measured N2O fluxes, soil NO3-N and NH4-N, and gravimetric water content (GWC) from vine and intervine (alleys) rows bimonthly (April-October) and monthly (November-March). Monthly, we collected soil samples for dissolved organic C (DOC) and dissolved organic N (DON) determination. Path analysis revealed that the effects of soil type and vineyard zone on N2O emissions were influenced by soil texture (i.e., gravel and clay contents) but that this effect was mediated by GWC through soil temperature and soil inorganic N content. Management practices such as irrigation, fertigation, cover cropping, and tillage affected differences between vine rows and alleys for soil inorganic pools, DOC, and DON from June to October 2012. This 20-mo study indicated that precipitation events strongly influenced N2O fluxes. C1 [Yu, Olivia T.; Steenwerth, Kerri L.] Univ Calif Davis, Dept Viticulture & Enol, Davis, CA 95616 USA.

TI Soil Organic Carbon and Nitrogen in Long-Term Manure Management System SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID WHEAT CROPPING SYSTEM; SILT LOAM; FERTILIZER APPLICATION; INORGANIC FERTILIZERS; CHEMICAL-PROPERTIES; GREAT-PLAINS; NO-TILLAGE; MATTER; DYNAMICS; PARTICULATE AB Long-term studies are extremely beneficial to our understanding and evaluation of changes in soil quality and sustainability of specific management practices. The objectives of this study were to evaluate the effects of 70 yr of intensive traditional tillage. Effect of moldboard plowing with manure (M) and inorganic fertilizer (F) additions on soil organic carbon (SOC), soil total nitrogen (STN), particulate organic matter (POM) and its associated carbon (POM-C), and mineral-associated organic matter carbon (MAOM-C) were quantified. The Knorr-Holden study was initiated in 1912 on a Tripp sandy loam (coarse-silty, mixed, superactive, mesic Aridic Haplustolls) with furrow irrigated, continuous corn (Zea mays L.) production. Soil samples were collected in 2011 from the 0-to 5-, 5-to 10-, 10-to 15-, 15-to 30-, 30-to 60-, and 60-to 90-cm depths. On fixed-depth basis, SOC and STN in the 0-to 30-cm layer increased by 2.3-fold compared with the 30-to 60-cm layer and by 3-fold compared with the 60-to 90 cm layer. Similar differences in SOC and STN were observed when calculated on an equivalent soil mass (ESM) basis. The application of inorganic fertilizer plus manure (F+ M) increased POM content in the 0-to 30-cm depth by 27 and 34% with 90+ M and 180+ M, respectively compared with F alone at 90 and 180 kg N ha-1. In the 0-to 15-cm soil depth, the relative POM-C to SOC content was 30% greater than in the 15-to 30-cm soil depth. In the 15-to 30-cm depth, the MAOM-C was 7% higher than the surface 0 to 15 cm. The MAOM-C represented 69% of SOC content associated with different treatments. Positive and significant correlations were found among SOC, POM-C, and MAOM-C. Our results indicate that measuring SOC distribution among different fractions, POM-C and MAOM-C, is important to improve our knowledge of SOC distribution as influenced by type of fertilization used at different depths. Overall, long-term manure amendment should be combined with F to enhance SOC and STN content in a system using intensive tillage and furrow irrigation.

(John) TI Evaluating Water Erosion Prediction Project Model Using Cesium-137-Derived Spatial Soil Redistribution Data SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID WEPP; RUNOFF; SENSITIVITY; CALIBRATION; PATTERNS; RATES; USLE AB The lack of spatial soil erosion data has been a major constraint on the refinement and application of physically based erosion models. Spatially distributed models can only be thoroughly validated with distributed erosion data. Fallout Cs-137 has been widely used to generate spatial soil redistribution data. The objectives of this study were to compare the soil redistribution patterns predicted using the Cs-137 technique and the Water Erosion Prediction Project (WEPP) model and to diagnose potential shortcomings in the configuration, functionality, and application of the WEPP model, if any. An experimental hillslope (80 m wide by 200 m long with 1-4% slope) was used. The plot was sampled in a 10-m grid for Cs-137 measurement. Measured rainfall, runoff, soil loss, and crop management were used to calibrate WEPP. Soil redistribution patterns predicted by the two methods were vastly different on the study hillslope. Compared with Cs-137, the average soil loss rates predicted by WEPP were overly sensitive to slope lengths exceeding 100 m if the 1-m default rill spacing was used. The spatial erosion patterns were well matched if different rill spacings along the hillslope were used. This study shows that rill spacing is a key input parameter for correctly simulating soil redistribution patterns with WEPP. Knowledge of rill distribution along a hillslope is critical to satisfactorily predicting rates of soil erosion and sediment deposition on a hillslope. The conclusion needs further testing on more hillslopes having different gradients and shapes. C1 [Zhang, X. C. (John)] USDA ARS, Grazinglands Res Lab, 7207 Cheyenne St, El Reno, OK 73036 USA.

TI Term Conventional and No-Tillage Effects on Field Hydrology and Yields of a Dryland Crop Rotation SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID SOUTHERN HIGH-PLAINS; SOIL-WATER STORAGE; US GREAT-PLAINS; CURVE NUMBERS; WINTER-WHEAT; CLAY LOAM; NITROGEN; INFILTRATION; CONSERVATION; RESIDUE AB Semiarid dryland crop yields with no-till (NT) residue management are often greater than stubble-mulch tillage (SM) because of improved soil conditions and water conservation, but information on long-term tillage effects on field hydrology and sustained crop production are needed. Our objective was to quantify the effects of NT and SM on stored soil water, runoff, and deep drainage through a clay loam soil in relation to crop growth and yield. Wheat (Triticum aestivum L.) and grain sorghum [Sorghum bicolor (L.) Moench] were grown in paired tillage treatments using a 3-yr wheat-sorghum-fallow (WSF) rotation from 1983 to 2013. We measured crop growth and yield factors, precipitation, runoff, and Cl concentration in variable increments to a 14.0-m depth. Cumulative runoff during the fallow periods after wheat and sorghum averaged 57 mm for NT compared with 33 mm under SM. Annual deep drainage averaged similar to 2 mm for SM and 14 mm for NT dryland crop production based on Cl displacement compared with no drainage below the root zone of adjacent native rangeland. Despite greater runoff and drainage, plant available soil water for the 1.8-m profile at wheat and sorghum planting averaged 194 mm for NT compared with 166 mm for SM because of reduced evaporation. Although wheat growth and grain yield did not vary with tillage, sorghum grain yield was 17% greater under NT, averaging 3420 versus 2920 kg ha(-1) under SM. We attributed the greater sorghum yield with NT to increased crop water use. C1 [Baumhardt, R. L.; Schwartz, R. C.; Marek, G. W.] USDA ARS, Bushland, TX 79012 USA. [Jones, O.

TI Genetic Bases of Fungal White Rot Wood Decay Predicted by Phylogenomic Analysis of Correlated Gene-Phenotype Evolution SO MOLECULAR BIOLOGY AND EVOLUTION LA English DT Article DE comparative genomics; bioinformatics; protein of unknown function; wood-decay; fungal enzymes ID PHANEROCHAETE-CHRYSOSPORIUM; GENOME; EXPRESSION; MODELS; DUPLICATION; PROFILES; LIGNIN; TREES; DEGRADATION; MECHANISMS AB Fungal decomposition of plant cell walls (PCW) is a complex process that has diverse industrial applications and huge impacts on the carbon cycle. White rot (WR) is a powerful mode of PCW decay in which lignin and carbohydrates are both degraded. Mechanistic studies of decay coupled with comparative genomic analyses have provided clues to the enzymatic components of WR systems and their evolutionary origins, but the complete suite of genes necessary for WR remains undetermined. Here, we use phylogenomic comparative methods, which we validate through simulations, to identify shifts in gene family diversification rates that are correlated with evolution of WR, using data from 62 fungal genomes. We detected 409 gene families that appear to be evolutionarily correlated with WR. The identified gene families encode well-characterized decay enzymes, e.g., fungal class II peroxidases and cellobiohydrolases, and enzymes involved in import and detoxification pathways, as well as 73 gene families that have no functional annotation. About 310 of the 409 identified gene families are present in the genome of the model WR fungus Phanerochaete chrysosporium and 192 of these (62%) have been shown to be upregulated under ligninolytic culture conditions, which corroborates the phylogeny-based functional inferences. These results illuminate the complexity of WR and suggest that its evolution has involved a general elaboration of the decay apparatus, including numerous gene families with as-yet unknown exact functions.

TI Effects of reduced in utero and post-weaning nutrition on milk yield and composition in primiparous beef cows SO ANIMAL LA English DT Article DE heifer development; milk and constituent yield; primiparous beef cow ID REPRODUCTIVE-PERFORMANCE; METABOLIZABLE PROTEIN; MAMMARY GROWTH; WEIGHT-GAIN; HEIFERS; CATTLE; EFFICIENCY; INTERVAL; SYSTEMS; FORAGE AB Development and long-term retention of replacement beef females in a semi-arid environment are of a major concern for extensive livestock producers. Furthermore, the demand of not only producing a thriving, healthy calf, but having sufficient milk to support that first calf is essential. To address this issue, we conducted a 3-year study measuring milk production and milk constituent yields in primiparous beef heifers (n=48; 16/year reared under two different feeding regimens) raising steer calves. Cows received 1.8 or 1.2 kg/day winter supplementation for similar to 80 day before parturition and their heifer calves were then randomly assigned to heifer development treatments that provided ad libitum (AL) or 80% (less than ad libitum (LAL)) of ad libitum feed post weaning. Heifers developed on the AL treatment also received 1.8 kg/day winter supplementation for life, whereas heifers developed on the LAL treatment received 1.2 kg/day winter supplementation for life. Milk production of primiparous cows was measured with a portable milking machine every other week from days 27 to 125 postpartum. Milk yield for the 125-day lactation period was calculated from area under the lactation curve approximated by trapezoidal summation. The ANOVA model included in utero winter nutrition, post-weaning heifer development treatment, year and their interaction. Heifers subjected to the AL treatment reached peak milk yield similar to 12.3 day later (P=0.02) than heifers receiving LAL treatment. In addition, an in utero nutritionxpost-weaning heifer treatmentxyear interaction existed (P <= 0.04) for milk peak yield, average daily milk yield (kg/day) and nutrient composition (protein, lactose, fat, solids non-fat, g/day). These interactions manifest as changes in magnitude and rank across the 3 years of the study. Livestock production in extensive environments is subject to variations in seasonal precipitation patterns and quality and quantity of grazeable forage and these fluctuations have a large impact on milk yield. In summary, the gestational nutritional environment of a heifer's mother may interact with the heifer's nutrient consumption during post-weaning growth and the current year to trigger variation in year-to-year milk production.

We identified climate factors correlated with localized changes in occupancy of snowshoe hares in Michigan, USA. A change in occupancy occurred if a site (similar to 7.5 ha) knowingly occupied by hares sometime in the past became unoccupied. We used local ecological knowledge to map sites where hares historically occurred and to assign a year of last-known occupancy. At 134 historically occupied sites, we conducted snow track surveys in 2013 to determine current occupancy status. We identified climate variables having relevance to hare population demographics and modeled the likelihood that those variables influenced current occupancy status. The top-ranking model included maximum temperature from 15 May to 19 January; as maximum temperature increased, the likelihood of a site becoming unoccupied increased. The second-ranked model included total number of days with measurable snow on the ground; as days with snow on the ground decreased, the likelihood of a site becoming unoccupied increased. Our data indicated that site occupancy status of hares can be described by climate variables and that the southern edge of snowshoe hare distribution in Michigan shifted northward by similar to 45 km over the last 20 years.

TI Effect of Steam During Fischer-Tropsch Synthesis Using Biomass-Derived Syngas SO CATALYSIS LETTERS LA English DT Article ID IRON-BASED CATALYSTS; CARBON-DIOXIDE; COBALT CATALYSTS; HIGHER ALCOHOLS; WATER; KINETICS; HYDROGENATION; CONVERSION; MANGANESE; GASIFIER AB Fischer-Tropsch synthesis (FTS) with biomass-derived syngas was performed using both iron-based 100Fe/6Cu/4K/25Al catalyst and ruthenium-based 5 % Ru/SiO2 catalyst. During FTS, different concentrations of steam were co-fed with the biomass-derived syngas to promote the water gas shift reaction and increase the H-2/CO ratio. On Fe-based catalysts the increase in steam concentration led to lower conversion, while deactivation is not observed on Ru-based catalysts. XRD of the spent iron-based catalyst showed the oxidation of iron carbides. Adding steam inhibited surface carbon deposition, as measured by temperature programmed hydrogenation. The iron carbide phase could be re-carburized by flowing CO. The addition of steam had different effects on these two catalysts. Fe-based catalyst showed significantly lower methane selectivity and greater C5+ hydrocarbon selectivity, while on the Ru-based catalyst, adding steam only showed slightly decreased methane selectivity.

These plants can cause acute cardiac failure often referred to as sudden death syndrome. The objective of this paper was to determine if N. stannea contains MFA and to report the clinical signs and pathology of cattle experimentally poisoned by this plant. MFA was detected in all N. stannea plant parts except mature leaves. Niedenzuella stannea was dosed to cattle at single doses of 15-30g kg(-1) bw. Clinical signs and pathology observed were similar to those reported by other MFA-containing plants. Animals showed marked tachycardia, labored breathing, muscle tremors, loss of balance, ataxia, falling, recumbence, pedaling movements, and opisthotonous leading to death in few minutes. Gross lesions included engorgement of the large veins, severe lung edema, and petechiae, ecchymosis and suffusions in the pericardium, epicardium and pleura. Histologically, hydropic vacuolar degeneration and necrosis of epithelial cells of the kidney were observed. Cattle that received daily doses of 4g kg(-1) body weight for 24 days showed no clinical signs. In summary, this is the first report that N. stannea contains monofluoroacetate and causes sudden death in cattle.

It is strictly herbivorous and its exposure to Toxoplasma gondii should be indicative of environmental contamination by oocysts. In the present study antibodies to T. gondii in 47 Brazilian tapirs maintained ex situ in 10 Brazilian and in one Paraguayan institution were sought in serum samples by the modified agglutination test (MAT >= 25). None of the animals presented clinical signs during the study. From 47 animals 35 (74.5%) were positive with titers of 25 in 8, 50 in 6, 100 in 12, 200 in 5, 400 in 1 and 800 in 3. One animal had samples collected on twice, and 19 were born in captivity. There was no association between occurrence of T. gondii antibodies and gender, and positive animals were reported in all institutions. The high occurrence of seropositive tapirs born ininstitutions (54.3%) confirmed the high exposure of these mammals to T. gondii in captivity. Only two cases of abortion were reported, but it was not possible to correlate these abortions to T. gondii infection.

The work used Google Earth Engine Landsat satellite and gridded climate archives for model evaluation. Model simulations across three decades indicated that the watershed operates on a threshold response to precipitation (P) >400mm/y to produce a positive yield (P-ET; 9%) resulting in stream discharge and a rebound in meadow groundwater levels during these wetter years. Observed and simulated meadow groundwater response to large P correlates with above average predicted soil moisture and with a normalized difference vegetation index threshold value >0.3. A return to assumed pre-expansion PJ conditions or an increase in temperature to mid-21st century shifts yielded by only +/- 1% during the multi-decade simulation period; but changes of approximately +/- 4% occurred during wet years. Changes in annual yield were largely dampened by the spatial and temporal redistribution of evapotranspiration across the watershed: Yet the influence of this redistribution and vegetation structural controls on snowmelt altered recharge to control water table depth in the meadow. Even a small-scale removal of PJ (0.5km(2)) proximal to the meadow will promote a stable, shallow groundwater system resilient to droughts, while modest increases in temperature will produce a meadow susceptible to declining water levels and a community structure likely to move toward dry and degraded conditions.

We estimated and analyzed the cumulative dry season drawdown of soil water across montane California using a spatially resolved water balance model that combined field, meteorological, and remote sensing observations. Dry season soil water drawdown varied markedly with elevation, increasing from <200mm/yr below 500m, to similar to 425mm/yr at 1000 to 2000m, before decreasing to <200mm/yr above similar to 3000m. Soil water drawdown was comparatively low at drier (mean annual precipitation<1000mm/yr) or colder (mean annual temperature<4 degrees C) locations; soil water drawdown was greater at wetter and warmer locations, including conifer forests. The reduced soil water drawdown at low-elevation dry locations may reflect inadequate precipitation to recharge the soil; the reduced water drawdown at high, cold locations presumably reflects limited storage capacity or sparse vegetation development. Soil water drawdown was reduced at locations that were glaciated during the Pleistocene and was only weakly related to rock type. The amount of soil water drawdown implies that many California ecosystems are deeply rooted, with conifer forest rooting to at least 3.6m. Deep rooting allows many California ecosystems to limit current summer moisture limitation and suggests some of these ecosystems may be able to also limit future increased moisture stress with climate warming if they are able to support increased evaporative demand by further tapping belowground moisture.

Here, we assessed groundwater recharge in different physiognomies of the cerrado located in an outcrop area of the Guarani Aquifer System. Water table fluctuations were measured from October 2011 through August 2013, by 58 monitoring wells distributed on four physiognomies of the undisturbed cerrado. We used multiple monitoring wells located in campo limpo (cerrado grassland), campo sujo (shrub cerrado), campo cerrado (open wooded cerrado), and cerrado sensu stricto (wooded cerrado), cover types. Recharge rates were computed for each well using the water table fluctuation method. The measured precipitation for hydrological years 2011-2012 and 2012-2013 were 1247 and 1194mm, respectively. We found values of average annual recharge of 363 +/- 87 mm, 354 +/- 85 mm, 324 +/- 78 mm, and 315 +/- 76 mm for campo limpo, campo sujo, campo cerrado, and cerrado sensu stricto, respectively. Our results suggest that recharge tends to decrease with the increase in the density of vegetation (grassland to woodland). These results indicate that water table depth may have an influence on the cerrado physiognomies or vice versa. Furthermore, replacement of undisturbed dense cerrado with croplands will likely alter recharge dynamics. Therefore, sound management of land use and land cover is needed to ensure future groundwater quantity and quality.

A third bovine pestivirus called HoBi-like virus has been detected in cattle and water buffalo in South America, Asia, and Europe. To date, no isolations of HoBi-like viruses from U.S. cattle have been reported. To assess exposure, 2,000 cattle sera, collected between 2014 and 2015 as part of the U.S. brucellosis surveillance program, were tested for antibodies against BVDV-1, BVDV-2, and HoBi-like viruses. In addition, RNA was extracted and tested by reverse transcription-polymerase chain reaction for the presence of pestiviruses; all samples tested negative. The percent of VN-positive samples was 91.3% for BVDV-1, 89.3% for BVDV-2, and 84.9% for HoBi-like viruses. Because the 3 bovine pestiviruses are antigenically cross-reactive, the comparative level of antibody against each pestivirus species was determined. Based on comparative titers, samples were segregated into 6 categories: no titers (7.6%), titers clearly higher against BVDV-1 (22.2%), titers substantially higher against BVDV-2 (9.1%), BVDV-1 and BVDV-2 titers equivalent but substantially higher than HoBi titers (25.7%), titers substantially higher against HoBi-like viruses (0%), and equivocal (35.4%). Titers tended to be higher against BVDV-1 than BVDV-2. However, the overall percentage of animals with titers below levels considered protective against acute bovine pestivirus infection were similar to 11% for BVDV-1, 12% BVDV-2, and 18% for HoBi-like virus.

Their effects on skink populations have been not often quantified on the mainland and are known primarily from skink population increases on islands from which mammals have been eradicated. Estimating skink population density with capture recapture trapping is time-consuming and costly. Counting skinks in artificial retreats in specific weather conditions may be a useful and relatively quick way to index population density, but needs calibration for different habitats and species. In 2007 and 2009, we estimated the population density of small terrestrial skinks (McCann's skink Oligosoma maccanni, southern grass skink O. aff. polychroma Glade 5 and cryptic skink O. inconspicuum), based on spatially explicit capture recapture (SECR) in pitfall traps in three mammal-management treatments at Macraes Flat, Otago. The treatments were eradication of large predators and near-eradication of rodents inside a mammal-resistant fence, suppression of mammalian predator populations through continuous trapping (two locations within an extensive area), and no mammal management. We tested for relationships between the estimated population densities and dawn and late-morning counts of skinks in artificial retreats. Skink density (three species combined) ranged from c. 1200 per ha at the experimental control site to c. 4000 per ha at the fenced site. These treatment differences in skink density may be the combined effect of predator management and pre-existing differences due to habitat characteristics and farming practices. Skink counts done in late morning (2009) were related to estimated skink densities but did not differ significantly between treatments. Skink counts done at dawn (both years) were not related to densities. Counts, but not densities, were significantly higher at locations with a more northerly aspect. We recommend further investigation of the utility of skink counts in artificial retreats for monitoring skink density at this location, with careful control of ambient temperature during sampling, and of aspect, habitat and device placement.

The immunized catfish showed significantly higher survival rate (95%) than those of mock-immunized control fish (0% survival) after the theront challenge. The gene expression of innate immune system, such as cytokines (IL-1 beta type a, IL-1 beta type b, IFN-gamma, TGF1-beta and TNF-alpha) and inflammatory proteins (NF-kB and iNOS 2), showed significant upregulation at day 1 (D1) post-immunization. Expression of TLR genes exhibited a rapid increase from hour 4 (h4) to D10 post-immunization. Genes of the adaptive response, such as the cell receptor MHC I, CD8(+), CD4(+) and TCR-alpha, showed upregulation at D1, D6 and D10. The TCR-beta expression increased rapidly at h4 and remained upregulated until D10. Immunoglobulin IgM upregulation was detected from h4 until D2 while IgD expression was increased from D1 until D10. Rapid upregulation of innate and adaptive immune genes in skin of catfish following live theront vaccination was demonstrated in this study ultimately resulting in significant protection against Ich infection.

Consequently, effects of cropping rotation and bio-covers were assessed on earthworm populations under no-tillage. Main effects of six different cropping [corn (Zea mays), cotton (Gossypium hirsutum), and soybean (Glycine max)] rotations ranging from monocultures to greater rotation complexity were implemented in four-year cycles for 12 years at two sites in Tennessee, USA with split-block bio-cover treatments of hairy vetch (Vicia villosa), wheat (Triticum aestivum), poultry litter, and a fallow control. Earthworms were collected to a 15 cm depth, hand sorted, and identified spring of 2013 and 2015 as one of three species (i.e., Diplocardia caroliniana, Lumbricus rubellus, or Amyntha spp.). Species richness and relative abundance were significantly affected by bio-covers and cropping sequences for both years at one site, but only by bio-covers at the other location. Under continuous cotton, overall earthworm populations" were reduced 55-68%, and D. caroliniana decreased as much as 88%. Conversely, sequences with soybean and corn had larger populations of D. caroliniana, which did not differ when in rotations, indicating favorable food sources in their rhizospheres. Poultry litter supported 2.2 times as many D. caroliniana and L. rubellus across locations and years, compared to cover crops and the control. Consequently, earthworm populations were greatest under nutrient rich bio-covers (poultry litter) and high residue, less pesticide intensive rotations (soybean and corn), suggesting a more dynamic soil ecology in these systems. Negative effects of cotton might be mitigated by fewer pesticide inputs, increased crop rotations, and poultry litter amendments. Published by Elsevier GmbH. C1 [Ashworth, A.

Thus, there is a need for the continued expansion of our molecular tool box. In support of this expansion, this study reports the design, construction, and validation of a new bicistronic shuttle vector series, pDUO, for the dual expression of genes in different hosts. Each vector was designed and constructed to contain two araC-pBAD inducible promoter systems for tight control over gene expression. Each araC-pBAD promoter precedes a ribosomal binding site and a multicloning site (MCS). The 5' end of MCS1 contains a sequence encoding an affinity HIS-tag N-terminus and MCS2 terminates with a sequence encoding an affinity S-tag C-terminus for one-step purification of recombinant proteins encoded by the inserted genes. Both MCS are followed by an rrnBT1 and T2 transcriptional terminator sequence. Each vector in this series also contains a PBR322 and pR01600-derived replicon to support replication in different host bacteria along with one of four different selectable markers. The functionality of the pDUO vector series was validated through the dual expression of oxalate biosynthetic component (obc) I and mrfp in Escherichia coli and Pseudomonas fluorescens. It is anticipated that this new vector series will facilitate functional studies as well as the engineering of bacterial strains for biotechnological purposes.

TI A Double-Blind Randomized Controlled Trial of Maternal Postpartum Deworming to Improve Infant Weight Gain in the Peruvian Amazon SO PLOS NEGLECTED TROPICAL DISEASES LA English DT Article ID SOIL-TRANSMITTED HELMINTHS; CHILD UNDERNUTRITION; DEVELOPING-COUNTRIES; TRICHURIS-TRICHIURA; DIAGNOSTIC-TESTS; GOLD STANDARD; RISK-FACTORS; HOOKWORM; HEALTH; INFECTIONS AB Background Nutritional interventions targeting the critical growth and development period before two years of age can have the greatest impact on health trajectories over the life course. Compelling evidence has demonstrated that interventions investing in maternal health in the first 1000 days of life are beneficial for both mothers and their children. One such potential intervention is deworming integrated into maternal postpartum care in areas where soil-transmitted helminth (STH) infections are endemic. Methodology/Principal Findings From February to August 2014, 1010 mother-infant pairs were recruited into a trial aimed at assessing the effectiveness of maternal postpartum deworming on infant and maternal health outcomes. Following delivery, mothers were randomly assigned to receive either single-dose 400 mg albendazole or placebo. Participants were followed-up at 1 and 6 months postpartum. There was no statistically significant difference in mean weight gain between infants in the experimental and control groups (mean difference: -0.02; 95% CI: -0.1, 0.08) at 6 months of age. Further, deworming had no effect on measured infant morbidity indicators. However, ad hoc analyses restricted to mothers who tested positive for STHs at baseline suggest that infants of mothers in the experimental group had greater mean length gain in cm (mean difference: 0.8; 95% CI: 0.1, 1.4) and length-for-age z-score (mean difference: 0.5; 95% CI: 0.2, 0.8) at 6 months of age. Conclusions/Significance In a study population composed of both STH-infected and uninfected mothers, maternal postpartum deworming was insufficient to impact infant growth and morbidity indicators up to 6 months postpartum. Among STH-infected mothers, however, important improvements in infant length gain and length-for-age were observed.

TI Soil Quality Evaluation Using the Soil Management Assessment Framework (SMAF) in Brazilian Oxisols with Contrasting Texture SO REVISTA BRASILEIRA DE CIENCIA DO SOLO LA English DT Article DE soil quality index; soil functions; soil indicators; soil use and management ID DYSTROPHIC RED LATOSOL; LIMITING WATER RANGE; LAND-USE CHANGE; NO-TILLAGE; PHYSICAL-PROPERTIES; GROUNDCOVER MANAGEMENT; SUGARCANE EXPANSION; INDEXING METHODS; CARBON STOCKS; ROOT-SYSTEM AB The Soil Management Assessment Framework (SMAF) was developed in the U.S.A. and has been used as a tool for assessing and quantifying changes in soil quality/health (SQ) induced by land uses and agricultural practices in that region and elsewhere throughout the world. An initial study using SMAF in Brazil was recently published, but additional research for a variety of soils and management systems is still needed. Our objective was to use data from five studies in southern Brazil to evaluate the potential of SMAF for assessing diverse land-use and management practices on SQ. The studies examined were: (i) horizontal and vertical distribution of soil properties in a long-term orange orchard; (ii) impacts of long-term land-use change from native vegetation to agricultural crops on soil properties; (iii) effects of short-term tillage on soil properties in a cassava production area; (iv) changes in soil properties due to mineral fertilizer and pig slurry application coupled with soil tillage practices; and (v) row and inter-row sowing effects on soil properties in a long-term no-tillage area. The soils were classified as Oxisols, with clay content ranging from 180 to 800 g kg(-1). Six SQ indicators [pH(H2O), P, K, bulk density, organic C, and microbial biomass] were individually scored using SMAF curves and integrated into an overall Soil Quality Index (SQI) focusing on chemical, physical, and biological sectors. The SMAF was sensitive for detecting SQ changes induced by different land uses and management practices within this wide textural range of Brazilian Oxisols. The SMAF scoring curve algorithms properly transformed the indicator values expressed in different units into unitless scores ranging from 0-1, thus enabling the individual indicators to be combined into an overall index for evaluating land-use and management effects on soil functions. Soil sector scores (i.e., chemical, physical, and biological) identify the principal soil limitations and can therefore be used to establish priorities for specific management actions. The SMAF can be used as a tool for assessing SQ in Brazilian soils, thus helping farmers, land managers, and politicians make better decisions regarding sustainable land-use and management practices.

A national model of linear extensibility percent (LEP) is needed to improve this process. The objective of this work was to develop and validate models for estimating LEP using general linear models and readily available soil survey properties. Measured data from the Kellogg National Soil Survey Laboratory database (Lincoln, Nebraska) were used to develop the prediction models. Twenty LEP prediction equations were developed based on pH and major mineralogy classes. Noncarbonate clay and, depending on the soil pH, either cation-exchange capacity or effective cation-exchange capacity explained between 42% and 86% of the total variation in LEP. Model equations using cation-exchange capacity as a predictive variable collectively produced a prediction root mean square error (RMSEp) of 1.44% and mean error (ME) of -0.16%. For low pH soils, the model equations using effective cation-exchange capacity as a predictive variable collectively produced an RMSEp of 1.29% and ME of -0.034%. The small negative MEs indicate an overall underestimation of LEP. Breaking down the validation results further among the different mineralogy groups produced a range of RMSEp from 0.42% to 1.80%. The smectitic group had the largest and the siliceous group had the lowest RMSEp. The prediction accuracy is considered adequate for soil survey purposes, and it is expected that LEP estimates will ultimately enhance soil survey interpretations. The models will be added to the soil survey database for soil scientists to use when measured data are not available.

As a result, beneficial reuse of this by-product is being sought to reduce landfilling and its associated cost. The use of this by-product as a low-cost soil amendment for suppling Ca and S to crops, improving soil structure, or reducing P loss from agricultural fields may be a viable alternative for easing the burden of disposal. In order to better understand the influence FGD gypsum has on nutrient losses in surface water runoff, rainfall simulations were conducted on an Ultisol (Luverne sandy loam; fine, mixed, semiactive, thermic Typic Hapludults) in a bermudagrass (Cynodon dactylon L.) hayfield typical of the US Coastal Plains region. Treatments consisted of applying 0, 2.2, 4.4, and 8.9 Mg ha(-1) FGD gypsum with 13.4 Mg ha(-1) poultry litter (PL) plus a nonfertilized check (no PL or FGD gypsum) and 8.9 Mg ha(-1) FGD gypsumonly as controls. All treatments were applied each May from 2009 to 2011. In 2011, two simulated rainfall events (similar to 89 mm h(-1)) were created to promote runoff for 60 min, one immediately after treatment application and the other 6 months later (end of growing season). The greatest nutrient losses observed were generally during the initial runoff event immediately following PL application. The addition of FGD gypsum alone generally increased Ca and S losses regardless of when the simulated runoff event occurred. Poultry litter additions increased inorganic N (NO3-N and NH4-N) and total P losses in both runoff events and K in the initial runoff event only. Adding FGD gypsum with PL decreased total P concentration losses while increasing NH4-N, Mg, and Mn, primarily in the initial runoff event. Concentrations of Al and Fe in runoff were generally minimal or below detection limits. C1 [Watts, Dexter B.; Torbert, H.

Two experiments were conducted to examine some aspects of yield stability for two biofuel species: switchgrass (Panicum vigratum L.) and Miscanthus x giganteus (Mxg). Biomass yields of these species were evaluated under various environmental conditions across the Southern Great Plains (SGP), including some sites with low soil fertility. In the first experiment, measured yields of four switchgrass ecotypes and Mxg varied among locations. Overall, plants showed optimal growth performance in study sites close to their geographical origins. Lowland switchgrass ecotypes and Mxg yields simulated by the ALMANAC model showed reasonable agreement with the measured yields across all study locations, while the simulated yields of upland switchgrass ecotypes were overestimated in northern locations. In the second experiment, examination of different N fertilizer rates revealed switchgrass yield increases over the range of 0, 80, or 160 kg N ha(-1) year(-1), while Mxg only showed yield increases between the low and medium N rates. This provides useful insights to crop management of two biofuel species and to enhance the predictive accuracy of process-based models, which are critical for developing bioenergy market systems in the SGP.

Ignition tests were performed over the course of an entire year for ten species (three species in year one, seven in year two) to evaluate seasonal changes in flammability. Ignition delay and mass loss rate at ignition were measured for a radiant heat flux of 50 kW/m(2) and flow velocity of 1 m/s. Large species-to-species variation occurred in two-variable linear correlations between moisture content, ignition time, and mass loss rate at ignition. Only a few species showed the same behavior as wet wood. Due to potential physical and chemical changes that live fuels undergo during the growing season, moisture content is not a particularly useful descriptor of ignition behavior for live fuels.

LANGENDOEN; OPEN-CHANNEL FLOW; DETACHMENT MODEL; RIVERBANK-STABILITY; SEDIMENT TRANSPORT; SUSPENDED SEDIMENT; SEEPAGE EROSION AB Streambank retreat is a complex cyclical process involving subaerial processes, fluvial erosion, seepage erosion, and geotechnical failures and is driven by several soil properties that themselves are temporally and spatially variable. Therefore, it can be extremely challenging to predict and model the erosion and consequent retreat of streambanks. However, modeling streambank retreat has many important applications, including the design and assessment of mitigation strategies for stream revitalization and stabilization. In order to highlight the current complexities of modeling streambank retreat and to suggest future research areas, this paper reviewed one of the most comprehensive streambank retreat models available, the Bank Stability and Toe Erosion Model (BSTEM), which has recently been integrated with several popular hydrodynamic and sediment transport models including the Hydrologic Engineering Center's River Analysis System (HEC-RAS). The objectives of this paper were to: (i) comprehensively review studies that have utilized BSTEM and report their findings, (ii) address the limitations of the model so that it can be applied appropriately in its current form, and (iii) suggest directions of research that will help make the model a more useful tool in future applications. The paper includes an extensive overview of peer reviewed studies to guide future users of BSTEM. The review demonstrated that the model needs further testing and evaluation outside of the central United States. Also, further development is needed in terms of accounting for spatial and temporal variability in geotechnical and fluvial erodibility parameters, incorporating subaerial processes, and accounting for the influence of riparian vegetation on streambank pore-water pressure dynamics, applied shear stress, and erodibility parameters.

However, scale mismatches between SIF and ground-based GPP have posed challenges toward fully exploiting these data. We used SIF obtained at high spatial sampling rates and resolution by NASA's Orbiting Carbon Observatory-2 satellite to elucidate GPP-SIF relationships across space and time in the U.S. Corn Belt. Strong linear scaling functions (R(2)0.79) that were consistent across instantaneous to monthly time scales were obtained for corn ecosystems and for a heterogeneous landscape based on tall tower observations. Although the slope of the corn function was similar to 56% higher than for the landscape, SIF was similar for corn (C-4) and soybean (C-3). Taken together, there is strong observational evidence showing robust linear GPP-SIF scaling that is sensitive to plant physiology but insensitive to the spatial or temporal scale.

TI Evaporator Fouling Tendencies of Thin Stillage and Concentrates From the Dry Grind Process SO HEAT TRANSFER ENGINEERING LA English DT Article; Proceedings Paper CT 11th International Conference on Heat Exchanger Fouling and Cleaning CY 2015 CL Enfield, IRELAND ID HEAT-TRANSFER; CORN-OIL; ETHANOL; FERMENTATIONS AB In the United States, more than 200 maize processing plants use multiple-effect evaporators to remove water from thin stillage and steepwater during dry grind and wet milling processes, respectively. During the dry grind process, unfermentables are centrifuged and the liquid fraction, thin stillage, is concentrated in multiple effect evaporators. Evaporator fouling occurs during thin stillage concentration and may be from deposition of proteins, fat, fiber, and/or carbohydrates on evaporator surfaces. Studies on evaporator fouling from maize processing streams are limited and fundamental causes are not well understood. Therefore, the overall objective was to investigate effects of compositional variation on evaporator fouling during thin stillage concentration. Effects of total solids during evaporator concentration, removal of post fermentation oil, corn oil and glycerol addition, and overall plant operation were studied. Thin stillage had lower fouling rates compared to evaporator concentrates. Addition of postfermentation corn oil (0.5 to 1.0% added) increased thin stillage fouling rates, but at higher oil concentration (1.5% added), rates decreased. At 10% solids content in evaporator concentrates, oil recovery had no influence on fouling rates. Glycerol addition (1%) to thin stillage increased fouling rates. Simultaneous plant shutdown and evaporator cleaning decreased subsequent fouling rates.

TI Automated prediction of sensory scores for color and appearance in canned black beans (Phaseolus vulgaris L.) using machine vision SO INTERNATIONAL JOURNAL OF FOOD PROPERTIES LA English DT Article DE Dry beans; Canning quality; Color and appearance; Visual assessment; Machine vision; Agreement among raters; Automation ID CANNING QUALITY; IMAGE-ANALYSIS AB Evaluation of canning quality of beans is commonly carried out by simple visual inspection that is time-consuming, resource intensive, and biased by the experience of the panelist. Moreover, there is not a standard scale to rate visual quality traits of canned beans. In this research, a machine vision system was implemented and tested for automatic inspection of color (COL) and appearance (APP) in canned black beans. Various color and textural image features (average, standard deviation, contrast, correlation, energy, and homogeneity from red, green, blue, lightness, red/green, yellow/blue, hue, saturation and value color scales) were extracted from beans and brine images, and evaluated to predict the quality rates for COL and APP of a group of bean panelists using multivariate statistics. Sixty-nine commercial canned black bean samples from different brands and markets were used for analysis. In spite of the "fair" agreement among the sensory panelists for COL and APP, as determined by multi-rater Kappa analysis, machine vision data based on partial least squares regression model showed high predictive performance for both COL and APP with correlation coefficients of 0.937 and 0.871, and standard errors of 0.26 and 0.38, respectively. When a classification was performed based on both COL and APP traits, a support vector machine model was able to sort the samples into two sensory quality categories of "acceptable" and "unacceptable" with an accuracy of 89.7%. Using simple color and texture image data, a machine vision system showed potential for the automatic evaluation of canned black beans by COL and/or appearance as a professional visual inspection.

TI A cyber-enabled spatial decision support system to inventory Mangroves in Mozambique: coupling scientific workflows and cloud computing SO INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE LA English DT Article DE Mangrove inventory; Zambezi Delta; spatial decision support system; scientific workflow; cloud computing ID FACILITY LOCATION; GIS; OPTIMIZATION; MANAGEMENT; FRAMEWORK; CYBERINFRASTRUCTURE; INTEGRATION; ALLOCATION; MODELS; FUTURE AB Mangroves are an important terrestrial carbon reservoir with numerous ecosystem services. Yet, it is difficult to inventory mangroves because of their low accessibility. A sampling approach that produces accurate assessment while maximizing logistical integrity of inventory operation is often required. Spatial decision support systems (SDSSs) provide support for integrating such a sampling design of fieldwork with operational considerations and evaluation of alternative scenarios. However, this fieldwork design driven by SDSS is often computationally intensive and repetitive. In this study, we develop a cyber-enabled SDSS framework to facilitate the computationally challenging fieldwork design that requires the efficacious selection of base camps and plots for the inventory of mangroves. Our study area is the Zambezi River Delta, Mozambique. Cyber-enabled capabilities, including scientific workflows and cloud computing, are integrated with the SDSS. Scientific workflows enable the automation of data and modeling tasks in the SDSS. Cloud computing offers on-demand computational support for interoperation among stakeholders for collaborative scenario evaluation for the fieldwork design of mangrove inventory. Further, this framework allows for harnessing high-performance computing capabilities for accelerating the fieldwork design. The cyberenabled framework provides significant merits in terms of effective coordination among science and logistical teams, assurance of meeting inventory objectives, and an objective basis to collectively and efficaciously evaluate alternative scenarios.

Many states require documentation of nuisance acres, and an evaluation of management success. Despite this need, no widely accepted "standard methods" for quantifying nuisance plants has been published. We review the most commonly used quantitative methods for monitoring plant distribution, species composition, and abundance, and make general recommendations to support management activities in monitoring plant populations and assessing management efficacy. It is important to choose an appropriate method to meet the goals and objectives of a given program, and to be willing to change methods as the needs and objectives of the program change. It is unlikely that the same monitoring and assessment method will be used throughout a program, especially a long-term program. We recommend choosing methods that are 1) quantifiable, that is, data can be statistically analyzed, 2) follow an appropriate sampling design, and 3) are repeatable and flexible enough to change on the basis of needs and personnel. Ideally, monitoring and assessment methods need to incorporate both target and nontarget impacts, collect data that are objective and can be quantified, and are labor and cost effective.

Plant populations were sampled on three dates from May to September 2014. A complex of indigenous herbivore and fungal taxa, mostly known from other Ludwigia spp., resulted in peak feeding and disease occurrence on 88% and 92% of sampled leaves, respectively. Herbivore damage declined over the growing season from 78 to 21% of sampled leaves, and disease symptom occurrence increased from 0 to 80%. Total leaf damage (percent leaf area) from both herbivory and disease was determined by software image analyses of floating and aerial leaves and reached 14% total reduction in photosynthetic tissues by September 2014. Aerial leaves were more commonly affected by disease symptoms, whereas floating leaves had a greater incidence of herbivore damage. Fourteen insect herbivore and seven fungal taxa were associated with L. hexapetala at Guntersville Reservoir. Despite the diverse assemblage of herbivores and fungi associated with L. hexapetala, damage was relatively low and the weed continues to persist as a nuisance species at this and other sites in southeastern United States. However, these results along with past surveys and literature review demonstrate the ability of common Ludwigia arthropod herbivores in the United States to host shift between Ludwigia spp. This begs the question as to how difficult it will be to locate potential biocontrol agents of L. hexapetala outside the United States that will be sufficiently host specific to present little to no risk to native Ludwigia spp. C1 [Harms, Nathan E.; Shearer, Judy F.] US Army Engineer Res & Dev Ctr, Vicksburg, MS 39180 USA.

Our objectives were to develop a rapid procedure for determining the long-term survivability of these cultures in acidified vegetable products and to identify suitable cultures for probiotic brined vegetable products. We therefore developed assays to measure acid resistance of these cultures to lactic and acetic acids, which are present in pickled vegetable products. We used relatively high acid concentrations (compared to commercial products) of 360 mM lactic acid and 420 mM acetic acid to determine acid resistance with a 1 h treatment. Growth rates were measured in a cucumber juice medium at pH 5.3, 4.2, and 3.8, at 30 degrees C and 0% to 2% NaCl. Significant differences in acid resistance and growth rates were found among the 10 cultures. In general, the acid resistant strains had slower growth rates than the acid sensitive strains. Based on the acid resistance data, selected cultures were tested for long-term survival in a simulated acidified refrigerated cucumber product. We found that one of the most acid resistant strains (Lactobacillus casei) could survive for up to 63 d at 4 degrees C without significant loss of viability at 10(8) CFU/mL. These data may aid in the development of commercial probiotic refrigerated pickle products. Practical Application The development of probiotic pickled vegetable products will be facilitated by identifying probiotics that can survive in acidified vegetable products with a proposed shelf life of 2 or more months. We analyzed the growth and acid resistance of 10 probiotic lactic acid bacterial cultures and found that cultures selected for acid resistance had superior long-term survival (up to 2 mo) in a simulated refrigerated probiotic vegetable product that included a fermentation step. These data may be useful to aid the development of a commercial process for the manufacture of probiotic pickles.

The use of the antistaling agent diacetyl tartaric acid esters of monoglycerides (DATEM) at 0.5% (flour basis) at each of the egg addition levels was also studied. Evaluated quality factors included color, specific volume, and crumb structure. Texture analysis was performed to evaluate the rate of quality loss based on changes in crumb hardness values over time. A trained sensory panel evaluated bread quality attributes by descriptive analysis. Sorghum breads with egg had larger specific volumes than the control, while DATEM had a negative effect on the volume of sorghum gluten-free bread. Inclusion of egg in the bread formula improved cell structure and produced darker crust (P < 0.05). The addition of egg reduced bread hardness and slowed the rate of quality loss over a 12-d storage period. Descriptive analysis confirmed the findings of texture analysis. Control breads were significantly harder (P < 0.05) than egg-containing bread at days 0 and 4. This research demonstrates that addition of eggs to a gluten-free sorghum bread formulation results in improved storage stability and better overall quality and acceptability of the product. Practical Application The results of this study demonstrate that DATEM addition to gluten-free sorghum-based breads has little or detrimental effects on bread quality and storage stability while addition of egg is beneficial to bread quality and storage stability. This study is beneficial to the food industry as it provides a better quality and longer lasting sorghum-based gluten-free bread.

A mineralization field trial was conducted to measure mass decomposition and N and carbon (C) amounts remaining from sunn hemp residue following three planting dates (May, June, and July) during the 2013 growing season at the Tennessee Valley (TVS) and Coastal Plain (WGS) locations of AL. Residue from June and July plantings contained 50.0% and 61.1% N at WGS and 41.5% and 66.5% N at TVS by the end of their respective incubation periods compared to residue from the May planting, which contained 21.1% N at WGS and 47.8% at TVS. In order to create a more synchronous relationship between AU Golden' residue N mineralization and crop demand, termination must be delayed until approximate planting of the following crop.

Merr) are a valuable source of high-quality edible lipids and protein. Despite dramatic breeding gains over the past 80 years, soybean oil continues to be oxidatively unstable, due to a high proportion of polyunsaturated triacylglycerols. Until recently, the majority of soybean oil underwent partial chemical hydrogenation. Mounting health concerns over trans fats, however, has increased breeding efforts to introgress mutant and biotechnological genetic alterations of soybean oil composition into high-yielding lines. As a result, there is an ongoing need to characterize fatty acid composition in a rapid, inexpensive and accurate manner. Gas chromatography is the most commonly used method, but near-infrared reflectance spectroscopy (NIRS) can be calibrated to non-destructively phenotype various seed compositions accurately and at a high throughput. Here we detail development of NIRS calibrations using intact seeds for every major soybean fatty acid breeding goal over an unprecedented range of oil composition. The NIRS calibrations were shown to be equivalent to destructive chemical analysis, and incorporation into a soybean phenotyping operation has the potential to dramatically reduce cost and accelerate phenotypic analysis.

The co-products from each method, along with CDS, were characterized for concentrations of key constituents (protein, oil, ash, glycerol and other carbohydrates), mineral profile, and amino acid composition. Recovery of mass and main constituents was also investigated. With the chemical method, about two-third of the mass went to the protein-mineral fraction, while by the physical method the equal amounts of mass went to the protein and glycerol-mineral fractions. Protein, minerals, and glycerol were mostly recovered into their respective fractions. CDS and its fractions contained six major minerals (Ca, Mg, P, K, Na, and S) and four trace ones (Cu, Fe, Mn, and Zn). Both chemical and physical treatments caused significant reduction of mineral contents (dry matter basis) in the protein or glycerol fraction. Several amino acids differed significantly in percent relative to total amino acids among fractions but the extent was not substantial for protein-rich fractions. These changes resulting from CDS fractionation are favorable for value added utilization of the new co-products.

This level of regulation is lacking in Saccharomyces cerevisiae strains engineered to metabolize xylose. To better control transcription in S. cerevisiae, the xylose-dependent, DNA-binding repressor (XylR) from Caulobacter crescentus was used to block transcription from synthetic promoters based on the constitutive Ashbya gossypii TEF promoter. The new hybrid promoters were repressed in the absence of xylose and showed up to a 25-fold increase in the presence of xylose. Activation of the promoter was highly sensitive to xylose with activity seen at concentrations below 2 mu M xylose. These new xylose-inducible promoters allow improved control of gene expression for engineered strains of Saccharomyces yeasts.

Corn, lettuce, soybean and zucchini were grown for 28 d in two different soils (agricultural, residential) amended with 0-2000 mg engineered nanoparticle (ENP) CeO2 kg(-1) and biochar (350 degrees C or 600 degrees C) at application rates of 0-5% (w/w). At harvest, plants were analyzed for biomass, Ce content, chlorophyll and lipid peroxidation. Biomass from the four species grown in residential soil varied with species and biochar type. However, biomass in the agricultural soil amended with biochar 600 degrees C was largely unaffected. Biochar co-exposure had minimal impact on Ce accumulation, with reduced or increased Ce content occurring at the highest (5%) biochar level. Soil-specific and biochar-specific effects on Ce accumulation were observed in the four species. For example, zucchini grown in agricultural soil with 2000 mg CeO2 kg(-1) and 350 degrees C biochar (0.5-5%) accumulated greater Ce than the control. However, for the 600 degrees C biochar, the opposite effect was evident, with decreased Ce content as biochar increased. A principal component analysis showed that biochar type accounted for 56-99% of the variance in chlorophyll and lipid per oxidation across the plants. SEM and mu-XRF showed Ce association with specific biochar and soil components, while mu-XANES analysis confirmed that after 28 d in soil, the Ce remained largely as CeO2. The current study demonstrates that biochar synthesis conditions significantly impact interactions with ENP, with subsequent effects on particle fate and effects. (C) 2016 Elsevier Masson SAS.

Understanding this vulnerability is critical for managing natural resources, particularly water resources that flow across jurisdictional boundaries, and support conflicting uses. This paper demonstrates Q-methodology, a promising participatory method infrequently applied in the vulnerability context, with a case study investigation of the vulnerability of stakeholders reliant on water-based ecosystem services derived from the Shoshone National Forest in Wyoming, USA. The approach identified four distinct viewpoints regarding vulnerability, including an environmental perspective, agricultural perspective, Native American perspective, and recreation perspective. The distinct viewpoints highlighted disparate levels of importance related to 34 water benefits, such as commercial irrigation, oil and natural gas extraction, river-based fishing, and cultural and spiritual use. A diverse range of drivers of change threatening important water benefits were also identified, including pollution, too much management intervention, and development of recreation opportunities. The potential benefits of Q-methodology for vulnerability assessment include a rank-ordering exercise that elicits preferences for tradeoffs, and statistical derivation of a small number of perspectives about the topic.

TI Curli Temper Adherence of Escherichia coli O157:H7 to Squamous Epithelial Cells from the Bovine Recto-Anal Junction in a Strain-Dependent Manner SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY LA English DT Article DE HEp-2; O157; RSE; STEC; adherence; bovine; curli; fimbriae; recto-anal junction ID BIOFILM FORMATION; CSGD PROMOTER; CELLULOSE EXPRESSION; CATTLE; O157-H7; O157/H7; COLONIZATION; INFECTIONS; PROTEINS; OUTBREAK AB Our recent studies have shown that intimin and the locus of enterocyte effacement-encoded proteins do not play a role in Escherichia coli O157:H7 (O157) adherence to the bovine recto-anal junction squamous epithelial (RSE) cells. To define factors that play a contributory role, we investigated the role of curli, fimbrial adhesins commonly implicated in adherence to various fomites and plant and human epithelial cells, in O157 adherence to RSE cells. Specifically, we examined (i) wild-type strains of O157; (ii) curli variants of O157 strains; (iii) isogenic curli deletion mutants of O157; and (iv) adherence inhibition of O157 using anti-curlin sera. Results of these experiments conducted under stringent conditions suggest that curli do not solely contribute to O157 adherence to RSE cells and in fact demonstrate a modulating effect on O157 adherence to RSE cells in contrast to HEp-2 cells (human epidermoid carcinoma of the larynx cells with HeLa contamination). The absence of curli and presence of blocking anti-curli antibodies enhanced O157-RSE cell interactions among some strains, thus alluding to a spatial, tempering effect of curli on O157 adherence to RSE cells when present. At the same time, the presence or absence of curli did not alter RSE cell adherence patterns of another O157 strain. These observations are at variance with the reported role of curli in O157 adherence to human cell lines such as HEp-2 and need to be factored in when developing anti-adherence modalities for preharvest control of O157 in cattle. IMPORTANCE This study demonstrated that O157 strains interact with epithelial cells in a host-specific manner. The fimbriae/adhesins that are significant for adherence to human cell lines may not have a role or may have a modulating role in O157 adherence to bovine cells. Targeting such adhesins may not prevent O157 attachment to bovine cells but instead may result in improved adherence. Hence, conducting host-specific evaluations is critical when selecting targets for O157 control strategies.

Recently, Salmonella enterica serovar Kentucky has been recognized as the most prominent serovar on carcasses in poultry-processing plants. Previous studies showed that flagella are one of the main factors that contribute to bacterial attachment to broiler skin. However, the precise role of flagella and the mechanism of attachment are unknown. There are two different flagellar subunits (fliC and fljB) expressed alternatively in Salmonella enterica serovars using phase variation. Here, by making deletions in genes encoding flagellar structural subunits (flgK, fliC, and fljB), and flagellar motor (motA), we were able to differentiate the role of flagella and their rotary motion in the colonization of broiler skin and cellular attachment. Utilizing a broiler skin assay, we demonstrated that the presence of FliC is necessary for attachment to broiler skin. Expression of the alternative flagellar subunit FljB enables Salmonella motility, but this subunit is unable to mediate tight attachment. Deletion of the flgK gene prevents proper flagellar assembly, making Salmonella significantly less adherent to broiler skin than the wild type. S. Kentucky with deletions in all three structural genes, fliC, fljB, and flgK, as well as a flagellar motor mutant (motA), exhibited less adhesion and invasion of Caco-2 cells, while an fljB mutant was as adherent and invasive as the wild-type strain. IMPORTANCE In this work, we answered clearly the role of flagella in S. Kentucky attachment to the chicken skin and Caco-2 cells. We demonstrated that the presence of FliC is necessary for attachment to broiler skin. Expression of the alternative flagellar subunit FljB enables Salmonella motility, but this subunit is unable to mediate strong attachment. Deletion of the flgK gene prevents proper flagellar assembly, making Salmonella significantly less adherent to broiler skin than the wild type. S. Kentucky with deletions in all three structural genes, fliC, fljB, and flgK, as well as a flagellar motor mutant (motA), exhibited less adhesion and invasion of Caco-2 cells, while an fljB mutant was as adherent and invasive as the wild-type strain. We expect these results will contribute to the understanding of the mechanisms of Salmonella attachment to food products. C1 [Salehi, Sanaz; Howe, Kevin; Bailey, R.

Two alternative biomass availability scenarios in 2030, defined as the (i) Business-as-usual (598 million dry tons) and (ii) Billion Ton (1042 million dry tons), establish a range of possible outcomes for the future bioeconomy. The biomass utilized in the current (2014) (365 million dry tons) economy is estimated to displace approximately 2.4% of fossil energy consumption and avoid 116 million tons of CO2-equivalent (CO(2)e) emissions, whereas the Billion Ton bioeconomy of 2030 could displace 9.5% of fossil energy consumption and avoid as much as 446 million tons of CO2 equivalent emissions annually. Developing the integrated systems, supply chains, and infrastructure to efficiently grow, harvest, transport, and convert large quantities of biomass in a sustainable way could support the transition to a low-carbon economy. Bio-based activities in the current (2014) economy are estimated to have directly generated more than $48 billion in revenue and 285 000 jobs. Our estimates show that developing biomass resources and addressing current limitations to achieve a Billion Ton bioeconomy could expand direct bioeconomy revenue by a factor of 5 to contribute nearly $259 billion and 1.1 million jobs to the US economy by 2030.

TI Effects of Inulin Chain Length on Fermentation by Equine Fecal Bacteria and Streptococcus bovis SO JOURNAL OF EQUINE VETERINARY SCIENCE LA English DT Article DE Fructan; Inulin; Oligofructose; Streptococcus; Hindgut acidosis ID PASTURE-ASSOCIATED LAMINITIS; IN-VITRO MODEL; CARBOHYDRATE OVERLOAD; FRUCTAN OLIGOMERS; FORAGE GRASSES; OLIGOFRUCTOSE; STRAINS; HINDGUT; HORSES; AMINES AB Grass fructans can be fermented by Gram-positive bacteria (e.g., Streptococcus bovis) in the equine hindgut, increasing production of lactic acid and decreasing pH. The degree of polymerization (DP) of fructans has been suggested to influence fermentation rates. The objective of the present study was to determine how DP impacts fermentation by equine fecal bacteria and a model S. bovis. Fecal microbes from three mares were harvested by differential centrifugation, washed, and resuspended in anaerobic media containing short chain (SC; DP <= 10) or long-chain (LC) inulin (DP >= 23) from 0% to 2% wt/vol. After 24 hours of incubation (37 degrees C), samples were collected for pH determination. Data were analyzed using the general linear models (GLM) procedure testing for the effect of treatment, concentration, and treatment x concentration (SAS v. 9.3). At all concentrations, the pH was lower in SC fermentations than in LC (P <.0001, in all cases). To determine the effect of DP on S. bovis, cultures were grown (39 degrees C, 9 hours) with 0.1%, 0.5%, or 1.3% SC or LC inulin. Optical density (600 nm) was determined by spectrophotometry. Maximum specific growth rates () were determined by linear regression (2-5 hours). Data were analyzed using the one-way analysis of variance procedure (SAS v. 9.3). The final optical density (600 nm), ix, and yield were higher with SC than with LC fermentation (P <.05). These results indicate that SC inulin may be more available for fermentation than LC inulin by equine fecal bacteria and S. bovis, specifically. Published by Elsevier Inc.

TI Capturing Spatial Variability of Biogeochemical Mass Exchanges and Reaction Rates in Wetland Water and Soil through Model Compartmentalization SO JOURNAL OF HYDROLOGIC ENGINEERING LA English DT Article ID STATISTICAL-MODEL; IDENTIFICATION; NITROGEN; CARBON AB A common phenomenon observed in natural and constructed wetlands is short-circuiting of flow and formation of stagnant zones that are only indirectly connected with the incoming water. Biogeochemistry of passive areas is potentially much different than that of active zones. In the research reported in this paper, the spatial resolution of a previously developed wetland nutrient cycling model was improved in order to capture the spatial variability of concentrations and reaction rates regarding nitrogen and carbon cycles throughout active and passive zones of wetlands. The upgraded model allows for several compartments in the horizontal domain, with all neighboring compartments connected through advective and dispersive/diffusive mass transport. The model was applied to data collected from a restored wetland in California that was characterized by the formation of a large stagnant zone at the southern end of the wetland due to close vicinity of the inlet and outlet structures in the northern end. Mass balance analysis revealed that over the course of the research period, about 23.4 +/- 3.9% of the incoming total nitrogen load was removed or retained by the wetland. It was observed that mass of all exchanges (physical and biogeochemical) regarding nitrogen cycling decreased along the activity gradient from active to passive zones. Model results also revealed that anaerobic processes become more significant along the activity gradient towards passive areas. (C) 2015 American Society of Civil Engineers.

TI Simultaneous Deletion of the 9GL and UK Genes from the African Swine Fever Virus Georgia 2007 Isolate Offers Increased Safety and Protection against Homologous Challenge SO JOURNAL OF VIROLOGY LA English DT Article DE 9GL; ASFV; African swine fever virus; UK; vaccine ID VIRULENCE-ASSOCIATED GENE; TUMOR-NECROSIS-FACTOR; PORCINE MACROPHAGES; HARBORING DELETIONS; PARENTAL VIRUS; INFECTION; PIGS; INTERFERON; EXPRESSION; ALPHA AB African swine fever virus (ASFV) is the etiological agent of a contagious and often lethal viral disease of domestic pigs that has significant economic consequences for the swine industry. The control of African swine fever (ASF) has been hampered by the unavailability of vaccines. Successful experimental vaccines have been derived from naturally occurring, cell culture-adapted, or genetically modified live attenuated ASFV. Recombinant viruses harboring engineered deletions of specific virulence-associated genes induce solid protection against challenge with parental viruses. Deletion of the 9GL (B119L) gene in the highly virulent ASFV isolates Malawi Lil-20/1 (Mal) and Pretoriuskop/96/4 (Delta 9GL viruses) resulted in complete protection when challenged with parental isolates. When similar deletions were created within the ASFV Georgia 2007 (ASFV-G) genome, attenuation was achieved but the protective and lethal doses were too similar. To enhance attenuation of ASFV-G, we deleted another gene, UK (DP96R), which was previously shown to be involved in attenuation of the ASFV E70 isolate. Here, we report the construction of a doublegene-deletion recombinant virus, ASFV-G-Delta 9GL/Delta UK. When administered intramuscularly (i.m.) to swine, there was no induction of disease, even at high doses (10(6) HAD(50)). Importantly, animals infected with 10(4) 50% hemadsorbing doses (HAD(50)) of ASFV-G-Delta 9GL/Delta UK were protected as early as 14 days postinoculation when challenged with ASFV-G. The presence of protection correlates with the appearance of serum anti-ASFV antibodies, but not with virus-specific circulating ASFV-specific gamma interferon (IFN-gamma)- producing cells. ASFV-G-Delta 9GL/Delta UK is the first rationally designed experimental ASFV vaccine that protects against the highly virulent ASFV Georgia 2007 isolate as early as 2 weeks postvaccination. IMPORTANCE Currently, there is no commercially available vaccine against African swine fever. Outbreaks of the disease are devastating to the swine industry and are caused by circulating strains of African swine fever virus. Here, we report a putative vaccine derived from a currently circulating strain but containing two deletions in two separate areas of the virus, allowing increased safety. Using this genetically modified virus, we were able to vaccinate swine and protect them from developing ASF. We were able to achieve protection from disease as early as 2 weeks after vaccination, even when the pigs were exposed to a higher than normal concentration of ASFV.

Because of the diverse types of chemical constituents found in such natural product extracts, a single chromatographic mode may not be sufficient for a comprehensive characterization. However, the combination of reversed-phase and aqueous normal phase LC can encompass a wide range of analyte polarity.

TI Minimally invasive collection of adipose tissue facilitates the study of eco-physiology in small-bodied mammals SO METHODS IN ECOLOGY AND EVOLUTION LA English DT Article DE bats; fatty acid signatures; fine-needle adipose aspiration; lipids; micro-adipose biopsy; movement ecology ID FINE-NEEDLE-ASPIRATION; FATTY-ACID-COMPOSITION; BATS EPTESICUS-FUSCUS; SEASONAL-VARIATION; BODY-COMPOSITION; MIGRATION; DIET; VARIABILITY; DIAGNOSIS; SURVIVAL AB Adipose tissue is the primary fuel storage for vertebrates and is an important component of energy budgets during periods of peak energetic demands. Investigating the composition of adipose tissue can provide information about energetics, migration, reproduction and other life-history traits. Until now, most field methods for sampling adipose tissue of small-bodied vertebrates have been destructive. Therefore, investigations of adipose tissue in small-bodied vertebrates have been limited in their broadscale application. We developed a field-ready micro-adipose biopsy method for sampling adipose tissue of small-bodied vertebrates, by adopting fine-needle adipose aspiration. We applied the method to silver-haired bats (Lasionycteris noctivagans) and then quantified the resulting fatty acid signatures of a summer group and an autumn group to demonstrate one possible application of the method. We successfully obtained interpretable fatty acid signatures from 745% of micro-adipose biopsy attempts, with success positively correlated with body mass index. Summer and autumn groups of bats had different fatty acid signatures likely representing varied available dietary compositions at resident sites (the habitat where adipose deposits are accumulated prior to migration). The fatty acid profile of autumn silver-haired bats was largely characterized by 16:0, 18:1 and 14:0, and the summer group was characterized by 16:0, 16:1 and 18:0. Our results suggest that fatty acid signatures have the potential to characterize the origins of migrating individuals, or the number of unique subpopulations being supported by a migration route. This field-ready fine-needle adipose aspiration method can be used on small-bodied mammals and modified for application to other small-bodied vertebrates. This non-destructive approach to sampling adipose tissue has great value because it allows for robust sample sizes, longitudinal studies of the same individuals across space and time, and sampling of rare, threatened and endangered species.

This tick poses unique difficulties in management because it can complete its entire life cycle indoors and has demonstrated acaricide resistance. The ability to monitor for tick presence and abundance is necessary for developing effective control programs. As such, an evaluation of adult brown dog tick behavioral responses to 16 potential semiochemicals was undertaken using Y-tube and straight-tube olfactometers. Both sexes of ticks were activated by nine of the 16 semiochemicals tested, including 300 mu g of 1-octen-3-ol, benzaldehyde, benzyl alcohol, hexanoic acid, nonanoic acid, methyl salicylate, o-nitrophenol, 2,6-dichlorophenol and salicylaldehyde. Rhipicephalus sanguineus s.l. behaviors including movement speed, direction and duration, as well as turning, were quantified following exposure to the same nine chemicals in a straight-tube olfactometer, individually at 300 mu g and as mixtures. Three individual chemicals, 1-octen-3-ol, hexanoic acid, and methyl salicylate induced strong responses. These three chemicals were evaluated in a semi-field setting using a modified bed bug trap but were found to provide no significant increase in attraction compared with CO2 alone. The results of these studies provide a foundation for future research regarding semiochemicals of R. sanguineus s.l. (C) 2016 Elsevier GmbH. All rights reserved.

Immature and adult female ticks infested three wild adult toads at a single site in the vicinity of a zoo south of Hilo, Island of Hawaii, Hawai`i, USA. We found no tick-infested toads on O'ahu or Maui. This tick infests cane toads in their native Neotropical range, but it was excluded from Hawai'i when the original founder toads were introduced over 80 years ago. The circumstances of our discovery suggest that A. rotundatum was independently and belatedly introduced to Hawai'i with imported zoo animals, and Hawai'i now joins Florida as the second U.S. state where this tick is established.

They are currently represented by at least seven serotypes and more than 40 subtypes. New clostridial strains that produce novel neurotoxin variants are being identified with increasing frequency, which presents challenges when organizing the nomenclature surrounding these neurotoxins. Worldwide, researchers are faced with the possibility that toxins having identical sequences may be given different designations or novel toxins having unique sequences may be given the same designations on publication. In order to minimize these problems, an ad hoc committee consisting of over 20 researchers in the field of botulinum neurotoxin research was convened to discuss the clarification of the issues involved in botulinum neurotoxin nomenclature. This publication presents a historical overview of the issues and provides guidelines for botulinum neurotoxin subtype nomenclature in the future.

Despite its discovery in A. flavus cultures approximately 40 years ago, its contribution to the A. flavus mycotoxin burden is consistently minimized by our focus on the more potent carcinogenic aflatoxins also produced by this fungus. Here, we report the screening and identification of several CPA-type alkaloids not previously found in A. flavus cultures. Our identifications of these CPA-type alkaloids are based on a dereplication strategy involving accurate mass high resolution mass spectrometry data and a careful study of the alpha-CPA fragmentation pattern. In total, 22 CPA-type alkaloids were identified in extracts from the A. flavus strains examined. Of these metabolites, 13 have been previously reported in other fungi, though this is the first report of their existence in A. flavus. Two of our metabolite discoveries, 11,12-dehydro alpha-CPA and 3-hydroxy-2-oxo CPA, have never been reported for any organism. The conspicuous presence of CPA and its numerous derivatives in A. flavus cultures raises concerns about the long-term and cumulative toxicological effects of these fungal secondary metabolites and their contributions to the entire A. flavus mycotoxin problem.

In this study, a simple thermal treatment was applied to a mixture of kraft lignin and copper sulfate for the synthesis of GECNs. The effect of temperature, duration time, temperature rising ramp, and argon gas flow rate were investigated on the quality of the GECNs. Temperature was found to be the most important factor in the growth of graphene; high temperature was preferred to obtain less defective graphene shells. Gas flow rate, duration time, and temperature rising ramp had less effect. The optimum synthesis parameters were proposed as 1000 degrees C, 30-min duration time, 20 degrees C/min temperature rising ramp, and 1200-sccm argon gas flow rate. Results showed that postheat treatment was a feasible way to improve the crystallinity of graphite. C1 [Leng, Weiqi] US Forest Serv, USDA, Forest Prod Lab, Madison, WI 53726 USA. [Barnes, H.

There was little evidence of change in the levels of these components with increasing landfill cell depth in softwood lumber, softwood plywood, or hardwood lumber. The results confirm studies at other landfills showing that wood degradation rates under anaerobic conditions in landfills are much slower than predicted and that models to predict these rates need to be modified.

One hundred and ninety-five surveys published in several forest products and forestry journals and proceedings (mostly North American based) were analyzed. Overall, the typical response rate was found to be about 26.0% (median) to 31.6% (mean). The median survey size in terms of number surveyed was 543.0, and the median for responses received was 131.5. Several factors were found to influence response rates and numbers surveyed. The results indicated that response rates were highest for surveys conducted at the regional or international level, that were interview based, and that were geared toward consumers. The majority of the surveys conducted were mail based (79.0%) and were directed at manufacturers (51.8%) followed by loggers (15.4%) and engineers (14.4%). There was no indication that the year of publication had an effect on observed response rates. Most studies reported testing for nonresponse bias (64.4%), with early vs late respondent comparisons being the most common method used. These results can be used as a benchmark for what have been typical response rates for survey-based research in the forest products industry.

This study compared several alternative leaching methods to a commonly used standard method, and to leaching under natural exposure conditions. Small blocks or lumber specimens were pressure treated with a wood preservative containing borax and copper hydroxide. The specimens were leached using scenarios involving short periods of immersion, simulated rainfall, or to a longer period of outdoor exposure to natural precipitation. When compared with lumber specimens exposed to natural precipitation, leaching from immersed small blocks overestimated losses of both copper and of boron, whereas immersion of lumber specimens underestimated losses of copper. Stirring during immersion, which is required by some standard methods, did not affect leaching. Simulated rainfall most closely simulated leaching during outdoor exposure, but is relatively complex and may be difficult to standardize. Leaching appeared to be directly related to the time that specimens had sufficient moisture to allow diffusion to occur. Further research is needed to better characterize moisture contents of wood products outdoors and develop methods that simulate those moisture conditions. C1 [Lebow, S. T.; Lebow, P. K.; Hirth, K.

Dynamic light scattering demonstrated that hand extrusion at 100 nm consistently resulted in liposomes of nearly 85 nm diameter for both phosphatidyl-hydroxytyrosol (DOPHT) and phosphatidyl-tyrosol (DOPT). Transmission electron microscopy showed DOPT and DOPHT liposomes extruded at 100-nm to be spherical and non-distinctive from one another. Zeta potential measurements resulted in surface charges < -25 mV, demonstrating both DOPT and DOPHT form highly stable liposomes. Quartz crystal microbalance with dissipation monitoring measurements demonstrated that liposomal adsorption was dependent on a combination of DOPT (or DOPHT) mole-percent and calcium ions concentration. Fluorescence anisotropy measurements indicated that melting temperatures of DOPT and DOPHT were below 4 degrees C, suggesting that adsorption behavior and liposome formation was limited by electrostatic interactions and not gel-state formation.

Previously, we identified a potential lectin-mediator (a rhamnose-binding lectin; RBL1a) of F columnare adhesion and showed higher RBL1a expression in susceptible channel catfish under basal conditions and following infection. Exposure of challenged fish to the carbohydrate ligand L-rhamnose just prior to a challenge substantially decreased columnaris mortality and pathogen adherence via the down-regulation of RBL1a. While highly effective in protecting fish from columnaris, L-rhamnose is prohibitively expensive, underscoring the need for alternative cost-effective sources of rhamnose for disease control. One such alternative may be microbially produced glycolipid compounds termed rhamnolipids (RLs), which feature abundant L-rhamnose moieties and are readily available from commercial sources. In the present study, we examined whether commercially available RLs (administered either by immersion or via feed) would function similarly to L-rhamnose in affording host protection against F. columnare. A four-week feeding trial with basal and RL top-coated diets (basal diet + RLs) was conducted in channel catfish fingerlings. Surprisingly, columnaris challenges revealed significantly lower survival following the 10 d challenge period in RL diet fed fish when compared with the basal treatment group (p < 0.001). In fish fed RLs, we observed a rapid and large-scale upregulation of RBL1a immediately after challenge combined with a suppression of mucin and lysozyme transcripts. Similarly, fish that were briefly pre-exposed to RLs by immersion and then challenged exhibited lower survival as compared to unexposed fish during a 4 d trial. In conclusion, RLs do not represent an alternative to rhamnose as an experimental treatment for protecting catfish from columnaris mortality. Further research is needed to find other affordable and efficacious alternative sources of L-rhamnose. (C) 2016 Elsevier Ltd. All rights reserved.

This Amaryllidaceae, which is indigenous of South Africa, was investigated for its alkaloid content, because the organic extract of its bulbs showed strong larvicidal activity with an LC50 value of 0.008 mu g mu L-1 against first instar Aedes aegypti larvae and with an LD50 value 4.6 mu g/mosquito against adult female Ac. aegypti, which is the major vector for dengue, yellow fever and the Zika virus. The extract did not show repellency at MED value of 0375 mg cm(2) against adult Ae. aegypti. Sarniensine was characterized using spectroscopic and chiroptical methods as (3aR,4Z,6S,7aS)-6-methoxy-3a-(2'-methoxymethyl-benzo [1,3]dioxol-1'-yl)-1-methyl-2,3,3a,6,7,7-hexahydro-1H-indole.

Freshly prepared, double sealed and double bagged CP (ca. 5 g) was pressure treated at 300, 400 and 500 MPa at 8 degrees C and 15 degrees C for 5 min. Microflora populations, soluble solid content, pH, color, antioxidant activity, appearance and aroma were measured at 1, 6, and 10 d of storage. Results showed that high pressure treatment of 300 MPa (8 degrees C and 15 degrees C) resulted in reduction of total aerobic plate count from 33 to 1.8 log CFU/g. The treatment reduced the populations of native aerobic plate count to non-detectable levels (detection limit 1 log CFU/g) at 400 MPa and 500 MPa pressures at 15 degrees C. Pressure treatment completely inactivated mold and yeast in puree below the limits of detection at day 1 and no regrowth was observed during 10 days of storage at 4 degrees C while mold and yeast in untreated puree survived during the storage. High pressure treatment did not show any adverse impact on physical properties as soluble solid content (SSC, 11.2 degrees Brix) and acidity (pH, 6.9). The instrumental color parameters (L*, a*, b*) were affected due to HHP treatment creating a slightly lighter product, compared to control, as indicated by higher L.* and lower a* values. However the change was not detected by the sensory panel while evaluating appearance scores. Pressure treatment did not affect the antioxidant capacity of puree product compared to control. Visual appearance and sniffing aroma test by panel revealed no adverse changes in the sensory parameters as a result of HHP treatment HHP method described in this study appears to be a promising way to inactivate spoilage microorganisms in the cantaloupe puree and maintain quality. This study provides a viable option for preservation and marketing this product. Published by Elsevier Ltd.

In this work, a novel polyurethane was developed involving xylan and tolylene-2,4-diisocyanate (TDI). Polymer synthesis was achieved through conventional heat or microwave-assisted reaction in dimethyl sulfoxide. Because xylan has multiple OH groups on each polymer chain, the TDI/xylan molar ratio had to be adjusted to produce a soluble polymeric product. The reaction products were characterized by C-13 NMR, FTIR, thermogravimetric analysis, and differential scanning calorimetry. The xylan polyurethane was shown to exhibit improved thermal stability over xylan. C1 [Cheng, H. N.] ARS, Southern Reg Res Ctr, USDA, 1100 Robert E Lee Blvd, New Orleans, LA 70124 USA.

When the solution ionic strength (IS) equaled 10 and 30 mM, the attachment rate coefficient (k(att)) increased up to 109% (p < 0.0002) and the percentage of the sand surface area that contributed to attachment (S-f) increased up to 160% (p < 0.002) when the temperature was increased from 4 to 20 degrees C. Temperature effects at IS = 10 and 30 mM were also dependent on the system hydrodynamics; i.e., enhanced retention at a lower pore water velocity (0.1 m/day). Conversely, this same temperature increase had a negligible influence on k(att) and S-f values when IS was 1 mM or >50 mM. An explanation for these observations was obtained from extended interaction energy calculations that considered nanoscale roughness and chemical heterogeneity on the sand surface. Interaction energy calculations demonstrated that the energy barrier to attachment in the primary minimum (Delta phi(a)) decreased with increasing IS, chemical heterogeneity, and temperature, especially in the presence of small amounts of nanoscale roughness (e.g., roughness fraction of 0.05 and height of 20 nm in the zone of influence). Temperature had a negligible effect on k(att), and S-f when the IS =1 mM because of the large energy barrier, and at IS = 50 mM because of the absence of an energy barrier. Conversely, temperature had a large influence on k(att) and S-f when the IS was 10 and 30 mM because of the presence of a small Delta phi(a) on sand with nanoscale roughness and a chemical (positive zeta potential) heterogeneity. This has large implications for setting parameters for the accurate modeling and transport prediction of virus and nanoparticle contaminants in ground water systems. (C) 2016 Elsevier B.V.

Woody plant cover can alter the timing and amount of plant available moisture in the soil and saprolite. To assess spatiotemporal subsurface moisture dynamics over two water years in a snow dominated western juniper stand we compared moisture dynamics horizontally across a discontinuous canopy, and vertically in soil and saprolite. We monitored soil moisture at 15 and 60 cm and conducted periodic electromagnetic induction and electrical resistivity tomography surveys aimed at sensing moisture changes within the root zone and saprolite. Timing of soil moisture dry down at 15 cm was very similar between canopy patches and interspace. Conversely, dry down at 60 cm occurred 22 days earlier in the interspace than under canopy patches. After rainfall, interspaces with more shrubs showed greater increases in soil moisture than interspaces with few shrubs. For the few rainfall events that were large enough to increase soil moisture at 60 cm, increases in moisture occurred almost exclusively below the canopy. Soil water holding capacity from 0 to 150 cm was a primary driver of areas that were associated with the greatest change in distributed electrical conductivity- an indicator of changes in soil moisture- across the growing season. Vegetation was also correlated with a greater seasonal change in electrical conductivity at these depths. The seasonal change in resistivity suggested moisture extraction by juniper well into the saprolite, as deep as 12 m below the surface. This change in deep subsurface resistivity primarily occurred below medium and large juniper trees. This study suggests how tree roots are both increasing infiltration below their canopy while also extracting moisture at depths of upwards of 12 m. Information from this study can help improve our understanding of juniper resilience to drought and the hydrologic impacts of semi-arid land cover change. (C) 2016 Elsevier B.V. All rights reserved.

Vanderlinden, Karl TI Concurrent temporal stability of the apparent electrical conductivity and soil water content SO JOURNAL OF HYDROLOGY LA English DT Article DE Soil-water content; Apparent electrical conductivity; Temporal stability; Soil spatial classification ID ELECTROMAGNETIC-INDUCTION; FIELD-SCALE; SPATIAL VARIABILITY; MOISTURE; DYNAMICS; PATTERNS; SITES AB Knowledge of spatio-temporal soil-water content (SWC) variability in agricultural fields is useful for improving crop management. Spatial patterns of SWC can be characterized using temporal stability analysis of difficult-to-obtain data from high spatial density and temporal frequency. Soil apparent electrical conductivity (ECa) measurements with high spatial density have been widely used to infer the spatial variability of SWC. The objective of this work is to test the hypothesis that temporal stability of ECa can be demonstrated and that relationships between temporal stability characteristics of SWC and ECa can be established. Apparent electrical conductivity and topsoil gravimetric SWC (theta) were periodically measured in an olive orchard in southwest Spain on 6 and 18 occasions, respectively. A temporal stability analysis of ECa elucidated three zones where ECa was close to, consistently substantially smaller than, and substantially larger than the spatial average ECa throughout the study period. Representative locations for theta were found with a chance of 75% within the representative zone for ECa. Yet, the driest locations, with consistently smaller 0 than the field average (), could be successfully identified (89%) within the zone with consistently smaller ECa than average. The theta - relations showed generally a linear behaviour, although a better fit was obtained at the highest theta using either exponential or power law equations at half of the locations. The former provided the best fit within the zone with ECa consistently smaller than average, while the latter performed best in the zone with ECa consistently larger than average. The linear equation provided the best fit within the representative ECa zone. This study demonstrates that temporal stability characteristics of ECa and SWC are linked and that ECa surveys can be used to delimit zones with representative locations for SWC measurement or estimation. Such information is of importance for a range of agricultural applications, i.e. irrigation, crop protection, fertilizer management, and soil and water conservation. (C) 2016 Elsevier B.V.

Plant orthologs of HsBAP31 termed 'plant BAP-like proteins' (PBL proteins) have thus far remained unstudied. Recently, the PBL protein from Nicotiana tabacum (NtPBL) was identified as an interactor of Nt-4/1, a plant protein known to interact with plant virus movement proteins and affect the long-distance transport of potato spindle tuber viroid (PSTVd) via the phloem. Here, we have compared the sequences of PBL proteins and studied the biochemical properties of NtPBL. Analysis of a number of fully sequenced plant genomes revealed that PBL-encoding genes represent a small multigene family with up to six members per genome. Two conserved motifs were identified in the C-terminal region of PBL proteins. The NtPBL C-terminal hydrophilic region (NtPBL-C) was expressed in bacterial cells, purified, and used for analysis of its RNA binding properties in vitro. In gel shift experiments, NtPBL-C was found to bind several tested RNAs, showing the most efficient binding to microRNA precursors (pre-miRNA) and less efficient interaction with PSTVd. Mutational analysis suggested that NtPBL-C has a composite RNA-binding site, with two conserved lysine residues in the most C-terminal protein region being involved in binding of pre-miRNA but not PSTVd RNA. Virus-mediated transient expression of NtPBL-C in plants resulted in stunting and leaf malformation, developmental abnormalities similar to those described previously for blockage of miRNA biogenesis/function. We hypothesize that the NtPBL protein represents a previously undiscovered component of the miRNA pathway. (C) 2016 Elsevier B.V. and Societe Francaise de Biochimie et Biologie Moleculaire (SFBBM).

The life history of this species, Sauris nr. purpurotincta (Lepidoptera: Geometridae), was examined and larval no-choice and adult multiple-choice host range tests were conducted in quarantine to evaluate their suitability for biological control of Chinese tallowtree. The results indicated that the larvae have five instars and require approximately 22 days to complete development to the adult stage. Host range tests indicated that the larvae could not feed and complete development on most species tested. However, 40% of the larvae survived when fed leaves of Hippomane mancinella, a state-listed endangered species in Florida, and all larvae survived when fed Morella cerifera, a common native species of the southeastern U.S.A. Multiple-choice oviposition tests indicated eggs were laid on leaves of both a south Florida native plant Gymnanthes lucida and Chinese tallowtree. Considering this broad host range, this species will not be considered further for biological control of Chinese tallowtree in the U.S.A. C1 [Fung, J.] SCA AmeriCorps, Ft Lauderdale, FL USA.

The shoot-tip-galling wasp Tetramesa romana was released in 2009 between Brownsville and Del Rio, Texas, and has dispersed over 800km along the river channel. Plots along the river were surveyed for shoot counts of arundo and all other plant species in 2016 at seven sites in regions in which prior studies had documented a 22% decline in arundo biomass (estimated from live shoot length) from 2007 to 2014. Estimated live biomass declined a further 32% between 2014 and 2016. Native plants accounted for 86% of the 44 species encountered in plots. Individual plots averaged five plant species, and arundo was most abundant in only 9 of 21 plots. Arundo live biomass and shoot density were negatively associated with plant diversity, indicating that live arundo interferes with germination and/or survival of other plant species. The proportion of dead shoots in plots, proportion of wasp-galled shoots, and density of exit holes made by emerging adult wasps per metre live main shoot length were positively associated with plant diversity in a combined model. Regressions indicated that the effects of wasp damage measures on diversity were mediated through their effects on main shoot mortality. By reducing live arundo biomass, the arundo wasp is fostering recovery of native plant communities at riparian sites along the Rio Grande.

This work investigated if results from proximate analysis could be used to assess the quality of the biochar. Normally, ultimate analysis results are used for this purpose. A large set of data was collected from literature and various mathematical correlation were investigated to determine if quality parameters such as carbon mass fraction and H/C and O/C mol ratios could be estimated from proximate analysis results. It was determined that the mass fraction of carbon in the biochar could be correlated to the mass fractions of volatile matter (VM), fixed carbon (FC), and ash (ASH) by the relationship C = 0.474 x VM+0.963 x FC+0.067 x ASH. The mass fraction of oxygen in biochar could also be correlated to VM, FC, and ASH, while hydrogen was best correlated to a relationship with VM, FC, and VM/FC. Atomic ratios, such as H/C and O/C, used for biochar classification by international standards and carbon sequestration potential, were best correlated to VM/FC by the expressions H/C = 0.379 x VM/ FC+0.251 and O/C = 0.188 x VM/FC+0.035. The developed correlations were proven to accurately classify biochar when the biochar had been made at >= 400 degrees C. Published by Elsevier Ltd. C1 [Klasson, K.

MOENCH; PLANTING DATE; BIOFUEL PRODUCTION; SUGAR; FEEDSTOCKS; JUICE; CLARIFICATION; YIELD; TECHNOLOGIES; MANUFACTURE AB Sweet sorghum is a promising feedstock crop for the manufacture of biofuels and bioproducts. Its large starch content may be an opportune source of untapped fermentable sugars to add economical value to sweet sorghum juices and processing by-products. In this study, four commercial cultivars, Dale, M81E, Theis, and Top 76-6 were grown in Louisiana (over 2 years) and studied at the milk (Mi), soft dough (SD), hard dough (HD), physiological (PM), and post-physiological (PPM) maturity stages to determine the value of sweet sorghum starch and the optimal cultivar, maturity, and environment ideal for processing and fermentation juice quality. Juice quality and physical crop attributes essential to processing and fermentation were strongly influenced by environmental and cultivar interactions (P < 0.0001); however, total sugars were specifically affected by cultivar and maturity interactions. Although a moderately strong correlation between total sugars and juice Brix was found (R = 0.767, P < 0.0001, n = 151), the use of Brix as an in-field harvesting indicator to predict stalk maturity is not recommended since it does not consider cultivar influences. Total sugars and total starch in extracted juice were greatest at HD maturity in Top 76-6 and M81E, respectively. Added-value (similar to 6-17%) can be theoretically obtained from starch if fermented in sweet sorghum juices, and possibly more when including other starch-rich processing by-products and seed-heads that can be recycled back into fermentations.

TI Impact of air pollution induced climate change on water availability and ecosystem productivity in the conterminous United States SO CLIMATIC CHANGE LA English DT Article DE Air pollution; Climate change; Water availability; Ecosystem productivity ID HYDROLOGICAL CYCLE; REGIONAL CLIMATE; MODEL EVALUATION; CONTINENTAL US; RIVER-BASIN; EAST-ASIA; PRECIPITATION; CHEMISTRY; EVAPOTRANSPIRATION; RESPONSES AB Air pollution from greenhouse gases and atmospheric aerosols are the major driving force of climate change that directly alters the terrestrial hydrological cycle and ecosystem functions. However, most current Global Climate Models (GCMs) use prescribed chemical concentrations of limited species; they do not explicitly simulate the time-varying concentrations of trace gases and aerosols and their impacts on climate change. This study investigates the individual and combined impacts of climate change and air pollution on water availability and ecosystem productivity over the conterminous US (CONUS). An ecohydrological model is driven by multiple regional climate scenarios with and without taking into account the impacts of air pollutants on the climate system. The results indicate that regional chemistry-climate feedbacks may largely offset the future warming and wetting trends predicted by GCMs without considering air pollution at the CONUS scale. Consequently, the interactions of air pollution and climate change are expected to significantly reduce water availability by the middle of twenty-first century. On the other hand, the combined impact of climate change and air pollution on ecosystem productivity is less pronounced, but there may still be notable declines in eastern and central regions. The results suggest that air pollution could aggravate regional climate change impacts on water shortage. We conclude that air pollution plays an important role in affecting climate and thus ecohydrological processes. Overlooking the impact of air pollution may cause evident overestimation of future water availability and ecosystem productivity.

TI Multiscale habitat relationships of snowshoe hares (Lepus americanus) in the mixed conifer landscape of the Northern Rockies, USA: Cross-scale effects of horizontal cover with implications for forest management SO ECOLOGY AND EVOLUTION LA English DT Article DE gradient modeling; habitat selection; habitat use; occupancy; quantile regression; Random Forest ID YELLOWSTONE-NATIONAL-PARK; CANADA LYNX; QUANTILE REGRESSION; RESOURCE SELECTION; PREDATION RISK; ABUNDANCE; DENSITY; CLIMATE; POPULATION; COLORADO AB Snowshoe hares (Lepus americanus) are an ecologically important herbivore because they modify vegetation through browsing and serve as a prey resource for multiple predators. We implemented a multiscale approach to characterize habitat relationships for snowshoe hares across the mixed conifer landscape of the northern Rocky Mountains, USA. Our objectives were to (1) assess the relationship between horizontal cover and snowshoe hares, (2) estimate how forest metrics vary across the gradient of snowshoe hare use and horizontal cover, and (3) model and map snowshoe hare occupancy and intensity of use. Results indicated that both occupancy and intensity of use by snowshoe hares increased with horizontal cover and that the effect became stronger as intensity of use increased. This underscores the importance of dense horizontal cover to achieve high use, and likely density, of snowshoe hares. Forest structure in areas with high snowshoe hare use and horizontal cover was characterized as multistoried with dense canopy cover and medium-sized trees (e.g., 12.7-24.4 cm). The abundance of lodgepole pine (Pinus contorta) was associated with snowshoe hare use within a mixed conifer context, and the only species to increase in abundance with horizontal cover was Engelmann spruce (Picea engelmannii) and subalpine fir (Abies lasiocarpa). Our landscape-level modeling produced similar patterns in that we observed a positive effect of lodgepole pine and horizontal cover on both occupancy and use by snowshoe hares, but we also observed a positive yet parabolic effect of snow depth on snowshoe hare occupancy. This work is among the first to characterize the multiscale habitat relationships of snowshoe hares across a mixed conifer landscape as well as to map their occupancy and intensity of use. Moreover, our results provide stand-and landscape-level insights that directly relate to management agencies, which aids in conservation efforts of snowshoe hares and their associated predators.

We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

TI Using species distribution models to define nesting habitat of the eastern metapopulation of double-crested cormorants SO ECOLOGY AND EVOLUTION LA English DT Article DE conservation; cormorant; metapopulation; nesting habitat; species distribution model; wildlife management ID MITOCHONDRIAL-DNA VARIATION; CLIMATE-CHANGE; LAND-COVER; SPATIAL AUTOCORRELATION; PHALACROCORAX-AURITUS; ECOLOGICAL NICHE; PRESENCE-ABSENCE; NORTH-AMERICA; CANADA GEESE; POPULATIONS AB When organisms with similar phenotypes have conflicting management and conservation initiatives, approaches are needed to differentiate among subpopulations or discrete groups. For example, the eastern metapopulation of the double-crested cormorant (Phalacrocorax auritus) has a migratory phenotype that is culled because they are viewed as a threat to commercial and natural resources, whereas resident birds are targeted for conservation. Understanding the distinct breeding habitats of resident versus migratory cormorants would aid in identification and management decisions. Here, we use species distribution models (SDM: Maxent) of cormorant nesting habitat to examine the eastern P. auritus metapopulation and the predicted breeding sites of its phenotypes. We then estimate the phenotypic identity of breeding colonies of cormorants where management plans are being developed. We transferred SDMs trained on data from resident bird colonies in Florida and migratory bird colonies in Minnesota to South Carolina in an effort to identify the phenotype of breeding cormorants there based on the local landscape characteristics. Nesting habitat characteristics of cormorant colonies in South Carolina more closely resembled those of the Florida phenotype than those of birds of the Minnesota phenotype. The presence of the resident phenotype in summer suggests that migratory and resident cormorants will co-occur in South Carolina in winter. Thus, there is an opportunity for separate management strategies for the two phenotypes in that state. We found differences in nesting habitat characteristics that could be used to refine management strategies and reduce human conflicts with abundant winter migrants and, at the same time, conserve less common colonies of resident cormorants. The models we use here show potential for advancing the study of geographically overlapping phenotypes with differing conservation and management priorities.

TI Acylcarnitines as markers of exercise-associated fuel partitioning, xenometabolism, and potential signals to muscle afferent neurons SO EXPERIMENTAL PHYSIOLOGY LA English DT Article DE branched chain amino acids; muscle fatigue; somatosensory system; T2DM; xenobiotic; xenometabolome ID HUMAN SKELETAL-MUSCLE; MODERATE-INTENSITY EXERCISE; TYPE-2 DIABETIC SUBJECTS; FATTY-ACID-METABOLISM; INSULIN-RESISTANCE; WEIGHT-LOSS; CARNITINE METABOLISM; PHYSICAL-ACTIVITY; CROSSOVER CONCEPT; LIPID-CONTENT AB New Findings What is the central question of this study? Does improved metabolic health and insulin sensitivity following a weight-loss and fitness intervention in sedentary, obese women alter exercise-associated fuel metabolism and incomplete mitochondrial fatty acid oxidation (FAO), as tracked by blood acylcarnitine patterns? What is the main finding and its importance? Despite improved fitness and blood sugar control, indices of incomplete mitochondrial FAO increased in a similar manner in response to a fixed load acute exercise bout; this indicates that intramitochondrial muscle FAO is inherently inefficient and is tethered directly to ATP turnover. With insulin resistance or type 2 diabetes mellitus, mismatches between mitochondrial fatty acid fuel delivery and oxidative phosphorylation/tricarboxylic acid cycle activity may contribute to inordinate accumulation of short- or medium-chain acylcarnitine fatty acid derivatives [markers of incomplete long-chain fatty acid oxidation (FAO)]. We reasoned that incomplete FAO in muscle would be ameliorated concurrent with improved insulin sensitivity and fitness following a approximate to 14week training and weight-loss intervention in obese, sedentary, insulin-resistant women. Contrary to this hypothesis, overnight-fasted and exercise-induced plasma C4-C14 acylcarnitines did not differ between pre- and postintervention phases. These metabolites all increased robustly with exercise (approximate to 45% of pre-intervention peak oxygen consumption) and decreased during a 20min cool-down. This supports the idea that, regardless of insulin sensitivity and fitness, intramitochondrial muscle -oxidation and attendant incomplete FAO are closely tethered to absolute ATP turnover rate. Acute exercise also led to branched-chain amino acid acylcarnitine derivative patterns suggestive of rapid and transient diminution of branched-chain amino acid flux through the mitochondrial branched-chain ketoacid dehydrogenase complex. We confirmed our prior novel observation that a weight-loss/fitness intervention alters plasma xenometabolites [i.e. cis-3,4-methylene-heptanoylcarnitine and -butyrobetaine (a co-metabolite possibly derived in part from gut bacteria)], suggesting that host metabolic health regulated gut microbe metabolism. Finally, we considered whether acylcarnitine metabolites signal to muscle-innervating afferents; palmitoylcarnitine at concentrations as low as 1-10m activated a subset (approximate to 2.5-5%) of these neurons ex vivo. This supports the hypothesis that in addition to tracking exercise-associated shifts in fuel metabolism, muscle acylcarnitines act as signals of exertion to short-loop somatosensory-motor circuits or to the brain.

However, little attention has been paid to the significant proteomic information encoded in the MS peaks that collectively constitute the MS 'fingerprint'. This review/perspective is intended to explore this topic in greater detail in the hopes that it may spur interest and further research in this area. Areas covered: This paper examines the recent literature on utilizing MALDI-TOF for bacterial identification. Critical works highlighting protein biomarker identification of bacteria, arguments for and against protein biomarker identification, proteomic approaches to biomarker identification, emergence of MALDI-TOF-TOF platforms and their use for top-down proteomic identification of bacterial proteins, protein denaturation and its effect on protein ion fragmentation, collision cross-sections and energy deposition during desorption/ionization are also explored. Expert commentary: MALDI-TOF and TOF-TOF mass spectrometry platforms will continue to provide chemical analyses that are rapid, cost-effective and high throughput. These instruments have proven their utility in the taxonomic identification of pathogenic bacteria at the genus and species level and are poised to more fully characterize these microorganisms to the benefit of clinical microbiology, food safety and other fields.

In this study, a line-scan high-throughput Raman imaging system was used to authenticate milk powder. A 5W 785nm line laser (240mm long and 1mm wide) was used as a Raman excitation source. The system was used to acquire hyperspectral Raman images in a wave number range of 103-2881cm(-1) from the skimmed milk powder mixed with two nitrogen-rich adulterants (i.e., melamine and urea) at eight concentrations (w/w) from 50 to 10,000 ppm. The powdered samples were put in sample holders with a surface area of 150x100mm and a depth of 2mm for push-broom image acquisition. Varying fluorescence signals from the milk powder were removed using a correction method based on adaptive iteratively reweighted penalised least squares. Image classifications were conducted using a simple thresholding method applied to single-band fluorescence-corrected images at unique Raman peaks selected for melamine (673cm(-1)) and urea (1009cm(-1)). Chemical images were generated by combining individual binary images of melamine and urea to visualise identification, spatial distribution and morphological features of the two adulterant particles in the milk powder. Limits of detection for both melamine and urea were estimated in the order of 50 ppm. High correlations were found between pixel concentrations (i.e., percentages of the adulterant pixels in the chemical images) and mass concentrations of melamine and urea, demonstrating the potential of the high-throughput Raman chemical imaging method for the detection and quantification of adulterants in the milk powder.

BUP6, a rumen bacterium, and optimization of parameters required for its production. Initial screening of five parameters (pH, temperature, agitation, incubation, and substrate concentration) was carried out employing Plackett-Burman design, which reduced the number of parameters to 3 (pH, temperature, and incubation) according to their significance on the yield of biosurfactant. A suitable statistical model for the production of biosurfactant by Pseudomonas sp. BUP6 was established according to Box-Behnken design, which resulted in 11% increase (at pH 7, 35 degrees C, incubation 75h) in the yield (2070mgL(-1)) of biosurfactant. The biosurfactant was found stable at a wide range of pH (3-9) with 48mgL(-1) critical micelle concentration; and maintained over 90% of its emulsification ability even after boiling and in presence of sodium chloride (0.5%). The highest cell hydrophobicity (37%) and emulsification (69%) indices were determined with groundnut oil and kerosene, respectively. The biosurfactant was found to inhibit the growth and adhesion of E. coli and S. aureus significantly. From the phytotoxicity studies, the biosurfactant did not show any adverse effect on the germinating seeds of rice and green gram. The structural characterization of biosurfactant employing orcinol method, thin layer chromatography and FT-IR indicated that it is a rhamnolipid (glycolipid). Thus, Pseudomonas sp. BUP6, a novel isolate from Malabari goat is demonstrated as a producer of an efficient rhamnolipid type biosurfactant suitable for application in various industries.

In this work, application of a rice husk-derived biochar to the surface of a sandy loam soil chamber reduced soil-air emissions of 1,3-D from 42% in a control (no biochar) to 8% due to adsorption onto the biochar. This adsorbed 1,3-D showed a potential for re-volatilization into air and solubilization into the soil-liquid phase. Biochar at the soil surface also reduced soil-gas concentrations in the upper soil; based on the determination of concentration-time values, this may limit 1,3-D-induced nematode control in the upper soil. In batch studies, the mixing of biochar into the soil severely limited nematode control; 1,3-D application rates around four times greater than the maximum permissible limit would be required to give nematode control under such conditions. Therefore, the use of biochar as a surface amendment, while showing an emission reduction benefit, may limit pest control during subsequent fumigations if, as seems probable, it is plowed into the soil.

SO JOURNAL OF ZOOLOGY LA English DT Article DE bird collisions; experience; FID; habituation; road ecology; rock pigeon; Columba livia ID AIRCRAFT; PREDATORS; BEHAVIOR; POPULATIONS; DIRECTION; STRIKES; NEURONS; URBAN AB Bird collisions with vehicles cause serious safety, financial and conservation concerns worldwide, but the causes of such collisions are poorly described. We investigated how experience with vehicles influenced avian avoidance responses. We trained three groups of vehicle-naive rock pigeons Columba livia with 32 near-miss vehicle approaches over 4weeks at 60 and 120km h(-1), and also included individuals that heard but did not see the approaches (control group). We subsequently measured flight initiation distance (FID) and whether individuals collided' with a virtual vehicle directly approaching at 120 or 240km h(-1) using video playback. We found that inexperienced individuals (i.e. the control group) had longer FIDs than experienced birds, although only one of 90 individuals across groups successfully avoided virtual collision. Vehicle approach speed during video playback and the interaction of approach speed and training group did not influence FID. Our results suggest that a habituation-like effect based on repeated observations of passing vehicles could contribute to ineffective vehicle avoidance responses by birds when collisions are imminent. Novel strategies should be developed to enhance avoidance responses to high-speed vehicles to minimize bird mortality. C1 [DeVault, T. L.; Seamans, T. W.; Blackwell, B.

Fungal translocation of N from the soil to the surface mulch has been confirmed in laboratories, but this mechanism has not been documented under field conditions. Experiments used N-15 (NH4)(2)SO4 , 99.7 at.%, which was uniformly injected below the soil surface at a rate of 1 mg (15) N kg(-1) soil. Some plots were treated with a fungicide (Captan) every 2 weeks after injection, while others were not treated. Nitrogen transfer was monitored by measuring levels in surface residue, soybean tissue, and extractable soil inorganic N pools. Despite the N release from the cereal rye (Secale cereale L.) tissues ranging from 15 to 50 kg N ha(-1), there was a detectable increase in N-15 enrichment of 10-15 % in the cereal rye tissue. Six weeks after injection, tissue from the plots not treated with fungicide contained 36 % more (15) N. The increased N-15 enrichment in the cereal rye mulch supports laboratory observations that soil inorganic N is translocated into surface mulch via fungal mechanisms. These findings illustrate microbial-mediated sinks for nitrogen in cereal rye mulches in no-till soybean production systems. C1 [Wells, M.

The objective of this study was to determine the dynamics and fate of effluent N applied to bermudagrass (Cynodon dactylon (L.) pers.) using N-15 tracer technology as influenced by irrigation date. Anaerobic swine lagoon effluent was labeled with enriched ((NH4)-N-15)(2)SO4 and applied to an acid silty clay soil. Microplots (1 x 1 m) were established for each irrigation event (main plots) and soil was sampled and bermudagrass was harvested on day 0, 1, 2, 3, 7, and 14 (subplots) following irrigation. Soil sampling coincided with harvests to monitor effluent derived N-15 transformations. Application in July when bermudagrass growth was most active resulted in a plant N-15 recovery of 59 %. Crop recoveries for June and September irrigation events were equal at 33 %. Nitrification of effluent NH4 (+)-N occurred rapidly within 24 h to 48 h following application. Rapid losses of effluent N-15 within 1 d suggest a high probability for NH3 volatilization, while losses following rainfall and high soil moisture content in June infer denitrification was most active. Lack of N-15 detection in the 30 to 60 cm soil depth indicated a low probability of leaching losses, while unaccounted for N-15 was 45, 5, and 30 % for irrigation events in June, July, and September, respectively. Bermudagrass recovery, dynamics and fate of effluent N applied to an acid soil varied with environmental conditions affecting crop growth and N uptake and soil N transformations.

In yeast two-hybrid system, we identified a number of Nicotiana benthamiana protein interactors of Nt-4/1, the protein known to affect systemic transport of potato spindle tuber viroid. For one of these interactors, an orthologue of human B-cell receptor-associated protein 31 (BAP31) termed plant BAP-like protein (PBL), the ability to interact with Nt-4/1 was studied in greater detail. Analyses of purified proteins expressed in bacterial cells carried out in vitro with the surface plasmon resonance (SPR) spectroscopy revealed that the N. tabacum PBL (NtPBL) was able to interact with Nt-4/1 with high-affinity, and that their complex can form at physiologically relevant concentrations of both proteins. Subcellular localization studies of 4/1-GFP and NtPBL-mRFP transiently co-expressed in plant cells revealed the co-localization of the two fusion proteins in endoplasmic reticulum-associated bodies, suggesting their interaction in vivo. The N-terminal region of the Nt-4/1 protein was found to be required for the specific subcellular targeting of the protein, presumably due to a predicted amphipathic helix mediating association of the Nt-4/1 protein with cell membranes. Additionally, this region was found to contain a trans-activator domain responsible for the Nt-4/1 ability to activate transcription of a reporter gene in yeast.

In this study, we examined six Global Climate Models (GCMs) under three Representative Concentration Pathways (RCPs) scenarios. First, the already impacted climate change was analyzed, based on the historical data available and then, the simulation results of the GCMs and RCPs were used for future scenario assessments. Results indicated that the annual mean temperature will likely be increased, ranging from 0.66 degrees C to 6.68 degrees C during the three future prediction periods (2020s, 2050s and 2080s), while the change in the annual precipitation ranged from -1.18% to 66.14%. Then, a well-known distributed hydrological soil vegetation model (DHSVM) was utilized to evaluate the effects of future climate change on the streamflow dynamics. The seasonal mean streamflows, predicted by the six GCMs and the three RCPs scenarios, were also shown to likely increase, ranging from -0.52% to 22.58%. Watershed managers and regulators can use the findings from this study to better implement their conservation practices in the face of climate change.

TI No-till with high biomass cover crops and invasive legume mulches increased total soil carbon after three years of collard production SO AGROECOLOGY AND SUSTAINABLE FOOD SYSTEMS LA English DT Article DE Albizia julibrissin; Brassica oleracea; Lespedeza cuneata; no-till; soil organic carbon ID ORGANIC-MATTER; CONVENTIONAL TILLAGE; CONSERVATION TILLAGE; PRODUCTION SYSTEMS; NITROGEN STORAGE; CROPPING SYSTEMS; HAIRY VETCH; ROTATION; CANADA; SEQUESTRATION AB Studies have shown that conversion to conservation tillage from conventional tillage does not increase total soil organic carbon (SOC) significantly in the short term (<5yrs). While no-till increases total SOC in the medium to long term, it was hypothesized that the inclusion of high biomass cover crops and organic mulches may increase total SOC in the short term. The use of invasive, perennial leguminous species as mulch may sustainably increase SOC during limited-input fall vegetable production. The objective of this study, conducted in Alabama (USA), was to quantify total SOC changes due to organic mulches and forage soybean (Glycine max (L.) Merr. cv. Derry) as a summer cover crop after conversion to no-till during limited-input fall collard (Brassica oleracea L.) production. Forage soybean as a summer cover crop did not increase SOC. No-till without mulch (control treatment) significantly increased SOC at 0-5cm from 6.3 to 14.0gkg(-1) soil in 3yrs, whereas inclusion of cut-and-carry mulches increased SOC to 22.6gkg(-1) soil. Treatments did not affect collard yield, which averaged 17,863kgha(-1) yr(-1). This represents a novel, limited-input system that may help control on-farm invasive species while sustainably increasing SOC in the short term. C1 [Mulvaney, M. J.; Wood, C.

Design: Secondary analysis. Setting: Multicenter institutions. Participants: A volunteer sample (N=1635) of sedentary men and women aged 70 to 89 years who were able to walk 400m but had physical limitations, defined as a Short Physical Performance Battery (SPPB) score of <= 9. Interventions: Moderate-intensity physical activity (n=818) consisting of aerobic, resistance, and flexibility exercises performed both center based (2times/wk) and home-based (3-4times/wk) sessions or health education program (n= 817) consisting of weekly to monthly workshops covering relevant health information. Main Outcome Measures: Physical function (gait speed over 400m) and lower extremity function (SPPB score) assessed at baseline and 6, 12, and 24 months. Results: Greater baseline physical function (gait speed, SPPB score) was negatively associated with change in gait speed (regression coefficient (3=.185; P<.001) and change in SPPB score (beta=-.365; P<.001), whereas higher number of steps per day measured by accelerometry was positively associated with change in gait speed (beta=.035; PG.001) and change in SPPB score (beta=.525; P<.001). Other baseline factors associated with positive change in gait speed and/or SPPB score include younger age (P<.001), lower body mass index (P<001), and higher self-reported physical activity (P =.002). Conclusions: Several demographic and physical activity related factors were associated with the extent of change in functional outcomes in participants in the LIFE, study. These factors should be considered when designing interventions for improving physical function in older adults with limited mobility.

Three experiments were conducted to select suitable host plants and agrowaste diluents for on-farm inoculum production. AM fungi (Claroideoglomus etunicatum NNT10, C. etunicatum PBT03 and Funneliformis mosseae RYA08) first were propagated using different culture materials (sterile sandy soil by itself or mixed 1:1 (v/v) with clay-brick granules, rice husk charcoal or vermiculite) and host plants (Mimosa invisa, Sorghum bicolor or Zea mays) in a greenhouse. Root colonisation and spore number of each AM fungus isolate were affected by host plant and substrate. Overall, spore population and root colonisation were highest when using Z. mays (3690 spores 100cm(-3) and 65% root length colonised) and vermiculite (3612 spores, 100cm(-3) and 63%). A subsequent survey experiment in a scaled-up on-farm system using the pooled inoculum produced in the greenhouse and a variety of host plants resulted in Z. mays being selected for the final experiment. The final experiment examined production of inoculum outdoors in large containers containing starter inoculum mixed with leaf litter compost, sand, and either vermiculite or one of the locally-available agrowastes oil palm bunches, stunted rice or wood chips. Results showed AM fungus spore production with oil palm bunches to be equivalent to that with the more expensive, imported vermiculite. The results indicate that leaf litter compost and oil palm bunches are suitable farm wastes for the on-farm production of AM fungal inoculum.

Here we discuss numerical strategies for solving the non-linear Langevin-based particle velocity evolution equation that eliminate such unphysical behaviour in both Reynolds-averaged and large-eddy simulation applications. Extremely large or 'rogue' particle velocities are caused when the numerical integration scheme becomes unstable. Such instabilities can be eliminated by using a sufficiently small integration timestep, or in cases where the required timestep is unrealistically small, an unconditionally stable implicit integration scheme can be used. When the generalized anisotropic turbulencemodel is used, it is critical that the input velocity covariance tensor be realizable, otherwise unphysical behaviour can become problematic regardless of the integration scheme or size of the timestep. A method is presented to ensure realizability, and thus eliminate such behaviour. It was also found that the numerical accuracy of the integration scheme determined the degree to which the second law of thermodynamics or 'well-mixed condition' was satisfied. Perhaps more importantly, it also determined the degree to which modelled Eulerian particle velocity statistics matched the specified Eulerian distributions (which is the ultimate goal of the numerical solution). It is recommended that future models be verified by not only checking the well-mixed condition, but perhaps more importantly by checking that computed Eulerian statistics match the Eulerian statistics specified as inputs.

Phytoplankton grew in response to increased NH4NO3 in the presence of all plant species, but was unaffected by exposure to permethrin. H. azteca responses occurred rapidly (0.17 days), was mitigated within 1-2 days, and aqueous toxicity was unaffected by plant species type. A toxic unit model approach ascertained primary toxicity was permethrin with minimal additional toxicity from NH4NO3. Varying aquatic plant species had only modest influences on phytoplankton responses and no observable influence on animal responses during nitrogen-permethrin mixture exposures. As a result, both T. latifolia and M. aquaticum can be used as part of an effective agricultural best-management practice system for mitigating pollutant impacts of agricultural run-off.

We characterized the joint influences of tree size, competition, and climate on diameter growth using hierarchical Bayesian methods applied to permanent sample plot data from the montane forests of Mount Rainier National Park, Washington State, USA, which are mostly comprised of Abies amabilis Douglas ex Forbes, Tsuga heterophylla (Raf.) Sarg., Pseudotsuga menziesii (Mirb.) Franco, and Thuja plicata Donn ex D. Don. Individual growth was sensitive to climate under low but not high competition, likely because tree ability to increase growth under more favorable climates (generally greater energy availability) was constrained by competition, with important variation among species. Thus, climate change will likely increase individual growth most in uncrowded stands with lower competition. However, crowded stands have more and (or) larger trees, conferring greater capacity for aggregate absolute growth increases. Due to these contrasting effects, our models predicted that climate change will lead to greater stand-scale growth increases in stands with medium compared with low crowding but similar increases in stands with medium and high crowding. Thus, competition will mediate the impacts of climate change on individual-and stand-scale growth in important but complex ways.

TI Thinning effects on foliar elements in eastern hemlock: implications for managing the spread of the hemlock woolly adelgid SO CANADIAN JOURNAL OF FOREST RESEARCH LA English DT Article DE eastern hemlock; foliar elements; foliar nutrients; thinning; hemlock woolly adelgid ID SOUTHERN NEW-ENGLAND; FOREST ECOSYSTEMS; TSUGA-CANADENSIS; PINE STANDS; LEAF-LITTER; WATER-USE; NUTRIENT; GROWTH; SPRUCE; INFESTATION AB Stand thinning is being tested as a means to limit the impacts of the invasive hemlock woolly adelgid (HWA; Adelges tsugae Annand) on eastern hemlock (Tsuga canadensis (L.) Carriere). The efficacy of this strategy may be reduced if thinning increases hemlock foliar nutrients because HWA densities are correlated with foliar concentrations of N, P, K, Ca, and Mn. We determined foliar N, P, K, Ca, and Mn concentrations in 1-year-old and all other (older) needles prior to and for 4 years after thinning in northwestern Pennsylvania stands of eastern hemlock without HWA. Average foliar concentrations in 1-year-old needles were 1.30-1.80 g N.100 g(-1), 1300-1700 mg P.kg(-1), 4200-6300 mg K.kg(-1), 2500-5200 mg Ca.kg(-1), and 2393 mu g Mn.g(-1). N, P, and K decreased, Ca increased, and Mn first increased and then stabilized. Thinning by itself did not affect the tested foliar nutrients. The interaction between treatment and year was significant and evident in temporal trajectories of foliar N and K. However, the differences between thinned and unthinned plots within years averaged only 0.03 g N.100 g(-1) and 340 mg K.kg(-1). We concluded that even though thinning changed the temporal trajectories of foliar N and K, the nutritional shifts were minimal, brief, and unlikely to affect the efficacy of thinning in limiting the impacts of HWA.

Don) Oerst. ex D.P. Little) decline has been used as an example of how changing climate can impact a tree species. However, most previous research has not placed yellow-cedar decline within the context of yellow-cedar overall. We used a 2004-2013 regional inventory of the temperate rainforest of Alaska (671 plots with yellow-cedar) to estimate current attributes and a subset of 564 remeasured plots (established 1995-1998) to estimate recent change. Results show that in unmanaged forests, yellow-cedar live tree basal area recently (1995-1998 to 2004-2013) increased, with a 95% confidence interval of a 0.3% to 3.3% increase per decade. Yellow-cedar has a relatively low mortality rate, 0.41% of trees per year. An analysis of live tree to snag ratios was consistent with elevated mortality of yellow-cedar prior to 1995 but also indicated that little range contraction had occurred. The large numbers and wide geographic range of yellow-cedar trees in Alaska and the recent (1995-2013) stability in the monitored population serve as important contextual information for yellow-cedar decline. This research also illustrates that understanding the spatial and temporal complexities of how tree species respond to climate change will be improved if focused studies are accompanied by regional monitoring.

We integrated field inventory, Landsat, and ecological variables to produce 30 m SI and MAI maps for the Tahoe National Forest (TNF) where different tree species coexist. We converted species-specific SI using adjustment factors. Then, the SI map was produced by (i) intensifying plots to expand the training sets to more climatic, topographic, soil, and forest reflective classes, (ii) using results from a stepwise regression to enable a weighted imputation that minimized the effects of outlier plots within classes, and (iii) local interpolation and strata median filling to assign values to pixels without direct imputations. The SI (reference age is 50 years) map had an R-2 of 0.7637, a root-mean-square error (RMSE) of 3.60, and a mean absolute error (MAE) of 3.07 m. The MAI map was similarly produced with an R-2 of 0.6882, an RMSE of 1.73, and a MAE of 1.20 m(3).ha(-1).year(-1). Spatial patterns and trends of SI and MAI were analyzed to be related to elevation, aspect, slope, soil productivity, and forest type. The 30 m SI and MAI maps can be used to support decisions on fire, plantation, biodiversity, and carbon.

TI Layer Stacking: A Novel Algorithm for Individual Forest Tree Segmentation from LiDAR Point Clouds SO CANADIAN JOURNAL OF REMOTE SENSING LA English DT Article ID VARIABLE WINDOW SIZE; SINGLE-TREE; AIRBORNE; HEIGHT; EXTRACTION; AREA; CROWNS AB As light detection and ranging (LiDAR) technology advances, it has become common for datasets to be acquired at a point density high enough to capture structural information from individual trees. To process these data, an automatic method of isolating individual trees from a LiDAR point cloud is required. Traditional methods for segmenting trees attempt to isolate prominent tree crowns from a canopy height model. We here introduce a novel segmentation method, layer stacking, which slices the entire forest point cloud at 1-m height intervals and isolates trees in each layer. Merging the results from all layers produces representative tree profiles. When compared to watershed delineation (a widely used segmentation algorithm), layer stacking correctly identified 15% more trees in unevenaged conifer stands, 7%-17% more in even-aged conifer stands, 26% more in mixedwood stands, and 26%-30% more (with 75% of trees correctly detected) in pure deciduous stands. Overall, layer stacking's commission error was mostly similar to or better than that of watershed delineation. Layer stacking performed particularly well in deciduous, leaf-off conditions, even those where tree crowns were less prominent. We conclude that in the tested forest types, layer stacking represents an improvement in segmentation when compared to existing algorithms.

This study integrated Landsat time-series data, a state-wide LiDAR dataset, and a recent cycle of the national forest inventory (NFI) records in Minnesota, USA, to obtain a spatially explicit inventory of AGB across a large region of space and time back to the 1990 baseline used by the US NGHGI. Pixel-level polynomial models were fit to 6 time-series metrics of Landsat data to obtain fitted predictors that were ultimately coupled with the NFI data in a nonparametric modeling framework to map temporal AGB baselines. Eighteen candidate models, formulated using different combinations of LiDAR and Landsat metrics, revealed that the model using both Landsat and LiDAR metrics consistently performed better than the alternative models. The RMSE of the model using both Landsat and LiDAR was 27.2 Mg ha(-1), against 31.39 Mg ha(-1) for the model using only LiDAR metrics. We conclude that the fitted Landsat-based model (RMSE = 47.64 Mg ha(-1)) provides acceptable accuracy for the 1990-baseline mapping of AGB.

In this study, the effect of salinity on the freshwater cyanobacterium, Fremyella diplosiphon, was investigated and mutagenesis-based efforts were undertaken to enhance salt tolerance. Salinity at a concentration of 10 g/L sodium chloride (NaCl) inhibited growth of wild type F. diplosiphon under white, red, and green light. Efforts to enhance halotolerance resulted in a mutant that could survive in 20 g/L NaCl for 15 generations with no significant reduction in phycobiliproteins (phycocyanin, phycoerythrin, and allophycocyanin) or chlorophyll a. Gene expression measured by quantitative reverse transcription-polymerase chain reaction revealed a three-fold increase in tripartite ATP-independent periplasmic transporters (TRAP) solute receptor transcript in the mutant compared to wild type. Our discovery of a TRAP transporter system in F. diplosiphon and its possible role in salinity response enables growth in brackish waters, which enhances its potential for biotechnological applications.

In this paper, we argue that there are two critical challenges for ecosystem science that are rooted in urban ecosystems: (1) predicting or explaining the assembly and function of novel communities and ecosystems under altered environmental conditions and (2) refining understanding of humans as components of ecosystems in the context of integrated social-ecological systems. We assert that these challenges are also linchpins in the further development of sustainability science and argue that there is a strong need for a new initiative in urban systems science to address these challenges and catalyze the next wave of fundamental advances in ecosystem science, and more broadly in interdisciplinary and transdisciplinary science.

SO ENVIRONMENTAL MANAGEMENT LA English DT Article DE GIS; Geospatial analysis; Parks and protected areas; Recreation conflict; Survey analysis; Zoning ID SOCIAL-VALUES CONFLICT; CROSS-COUNTRY SKIERS; GPS AB Parks and protected area managers use zoning to decrease interpersonal conflict between recreationists. Zoning, or segregation, of recreation-often by non-motorized and motorized activity-is designed to limit physical interaction while providing recreation opportunities to both groups. This article investigated the effectiveness of zoning to reduce recreation conflict in the Vail Pass Winter Recreation Area in Colorado, USA. Despite a zoning management system, established groomed travel routes were used by both non-motorized recreationists (backcountry skiers, snowboarders, snowshoers) and motorized recreationists (snowmobilers). We hypothesized that persistent recreation conflict reported by non-motorized recreationists was the result of recreation occurring in areas of mixed non-motorized and motorized use, mostly along groomed routes. We performed a geospatial analysis of recreation [from Global Positioning System (GPS) points, n = 1,233,449] in the Vail Pass Winter Recreation Area to identify areas of mixed non-motorized and motorized use. We then surveyed non-motorized recreationists (n = 199) to test whether reported conflict is higher for respondents who traveled in areas of mixed-use, compared with respondents traveling outside areas of mixed-use. Results from the geospatial analysis showed that only 0.7 % of the Vail Pass Winter Recreation Area contained recreation from both groups, however that area contained 14.8 % of all non-motorized recreation and 49.1 % of all motorized recreation. Survey analysis results showed higher interpersonal conflict for all five standard conflict variables among non-motorized respondents who traveled in areas of mixed-use, compared with those traveling outside mixed-use areas. Management implications and recommendations for increasing the effectiveness of zoning are provided.

TI Genetics of resistance in lettuce to races 1 and 2 of Verticillium dahliae from different host species SO EUPHYTICA LA English DT Article DE Breeding; Disease; Disease resistance; Diversity; Genetic; Host-pathogen interaction; Lactuca sativa; Vegetable; Verticillium wilt ID LACTUCA-SATIVA L.; WILT; INHERITANCE AB Race 1 resistance against Verticillium dahliae in lettuce was originally shown in the cultivar La Brillante to be conditioned by a single dominant gene (Verticillium resistance 1, Vr1). Multiple, morphologically diverse sources of germplasm have been identified as resistant to race 1. In this study, allelism tests indicated that resistance in these different lettuce cultivars is closely linked or allelic to the Vr1 gene. The Vr1 gene is defeated by race 2 isolates of V. dahliae. Only partial resistance to race 2 isolates is available in a few plant introductions (PIs). Greenhouse and field experiments conducted with these PIs demonstrated partial resistance to V. dahliae race 1 as well as race 2 isolates from lettuce. Cultivars resistant to race 1 and PIs with partial resistance to race 2 were challenged with several race 1 and 2 isolates originating from hosts other than lettuce. This indicated that cultivars resistant to race 1 and the breeding lines derived from them would also be resistant to race 1 isolates from other hosts; similarly, the partial resistance would be effective against race 1 and 2 isolates from hosts other than lettuce. Nevertheless, there were specific interactions that warrant further study. Although race 1 currently predominates in the major lettuce production area of the Salinas Valley, CA, breeding lettuce for resistance to V. dahliae should take both races into account.

Since the existing models for calculating the mechanical behavior of core configurations within sandwich panels are very complex, a new simplified orthogonal model (SOM) using an equivalent element has been developed. This model considers both linear and nonlinear geometrical effects when used to analyze the mechanical properties of 3DESP by transforming repeated elements from a tri-axial ribbed core for bending. Two different conditions were studied in comparison with finite element method (FEM) and I-beam equation. The results showed the SOM was consistent with FEM and the experimental result and were more accurate than the I-beam equation. The SOM considering nonlinear geometric deformation needed more computational effort and was found to match well with a FEM model and had slightly better accuracy compared with the linear SOM. Compared with FEM, the parameters in the linear SOM were easier to modify for predicting point-by-point bending performance. However, while the FEM can provide advanced characteristics of the 3DESP such as strain distribution, the linear SOM provided acceptable deformation accuracy and is proposed for preliminary design with multiple parameters. FEM should be applied for advanced analyses. C1 [Li, Jinghao; Hunt, John F.; Cai, Zhiyong] US Forest Serv, USDA, Forest Prod Lab, Madison, WI 53726 USA.

TI Electrostatic and Conventional Spraying of Alginate-Based Edible Coating with Natural Antimicrobials for Preserving Fresh Strawberry Quality SO FOOD AND BIOPROCESS TECHNOLOGY LA English DT Article DE Carvacrol; Methyl cinnamate; Alginate coating; Essential oils; Shelf-life; Physicochemical parameters ID METHYL CINNAMATE; PLANT-EXTRACTS; CARVACROL; FRUIT; TECHNOLOGY; DEPOSITION; SPINACH; SYSTEM; AGENTS; FILMS AB Microbial contamination and mold growth are common causes of strawberry deterioration during storage. The growing need for extending shelf-life while enhancing the overall quality of perishable fruits has generated increasing interest in the development of novel preservation technologies. This study used electrostatic spraying (ES) technology as an innovative and efficient technique for the application of edible alginate coating enriched with carvacrol and methyl cinnamate (natural antimicrobials) on fresh strawberries. The efficiency of the electrostatic technology was compared to non-electrostatic (conventional) spray (NES) technology in terms of transfer efficiency and coating evenness. Furthermore, physicochemical and textural parameters (such as weight loss, visible decay, firmness, surface color, total soluble phenolic content, and antioxidant capacity) of ES and NES coated fruits were studied and compared to uncoated controls. ES technology demonstrated higher transfer efficiency and evenness than NES, which led to a significant reduction of visible decay over uncoated controls. The delay in microbial spoilage by ES (11 days) was greater than by NES (10 days) and uncoated strawberries (7 days). ES coating significantly inhibited strawberry decay with only 5.6 % of infected fruits, compared to 16.6 and 8.3 % for control and NES fruits after 13 days of storage, respectively. At the end of 13 days of storage, ES coating demonstrated superior performance on strawberry firmness, color retention, and weight loss reduction. Additionally, no differences were observed between uncoated and coated fruits with regard to their antioxidant and total soluble phenolics.

Discovered as a factor essential for rat fertility and soon after characterized for its properties of fat-soluble antioxidant, vitamin E was identified to have signaling and gene regulation effects in the 1980s. In the same years the cytochrome P450 dependent metabolism of vitamin E was characterized and a first series of studies on short-chain carboxyethyl metabolites in the 1990s paved the way to the hypothesis of a biological role for this metabolism alternative to vitamin E catabolism. In the last decade other physiological metabolites of vitamin E have been identified, such as alpha-tocopheryl phosphate and the long-chain metabolites formed by the w-hydroxylase activity of cytochrome P-450. Recent findings are consistent with gene regulation and homeostatic roles of these metabolites in different experimental models, such as inflammatory, neuronal and hepatic cells, and in vivo in animal models of acute inflammation. Molecular mechanisms underlying these responses are under investigation in several laboratories and side-glances to research on other fat soluble vitamins may help to move faster in this direction. Other emerging aspects presented in this review paper include novel insights on the mechanisms of reduction of the cardiovascular risk, immunomodulation and antiallergic effects, neuroprotection properties in models of glutamate excitotoxicity and spino-cerebellar damage, hepatoprotection and prevention of liver toxicity by different causes and even therapeutic applications in non-alcoholic steatohepatitis. We here discuss these topics with the aim of stimulating the interest of the scientific community and further research activities that may help to celebrate this anniversary of vitamin E with an in-depth knowledge of its action as vitamin.

This research investigated the interactive effects of elevated [CO2], warming and soil water deficit on biomass production, leaf-level physiological responses and whole-plant water use efficiency (WUEP) in cotton (Gossypium hirsutum L.). Cotton was grown in the glasshouse under two [CO2] treatments (CA, 400 mu L L-1; C-E, 640 mu L L-1) and two temperature treatments (T-A, 28 degrees C : 17 degrees C day : night; T-E, 32 degrees C : 21 degrees C day : night). Plants were subjected to two progressive water deficit cycles, with a 5-day recovery period between the water deficit periods. C-E increased vegetative biomass and photosynthetic rates, and decreased stomatal conductance in T-A; however, these responses to C-E were not evident under T-E. C-E increased whole-plant water loss under T-A, but increased WUEp, whereas increased whole-plant water loss in T-E decreased WUEp regardless of atmospheric [CO2]. C-E may provide some positive growth and physiological benefits to cotton at T-A if sufficient water is available but C-E will not mitigate the negative effects of rising temperature on cotton growth and physiology in future environments.

It produces darkly pigmented resting structures known as microsclerotia, which are able to survive for up to 14 years in soil, and represent one of the defining characteristics of this species. The pigment produced in V. dahliae is dihydroxynaphthalene (DHN)-melanin, a form of melanin common among fungi and named so for the intermediary of this melanin biosynthetic pathway. In this study, we characterized the function of the V. dahliae Vayg1 gene, whose homologs were involved in melanin biosynthesis in Exophiala dermatitidis (Wayg1) and Aspergillus fumigatus (Aayg1), by deletion and complementation of the gene and co-incubating deletion mutant with wild-type strain. Results showed that melanin production and microsclerotial formation in deletion mutants are inhibited. The Vayg1 deletion mutant also exhibited reduced pathogenicity. These results showed that Vayg1 is necessary for melanin and microsclerotium production, and we may thus hypothesize that the Vayg1 product may catalyze two different precursors, one of which is essential for DHN melanin production and the other one is involved in a signal network for microsclerotial formation in V. dahliae.

TI Disruptions of the genes involved in lysine biosynthesis, iron acquisition, and secondary metabolisms affect virulence and fitness in Metarhizium robertsii SO FUNGAL GENETICS AND BIOLOGY LA English DT Article DE 4 ' Phosphopantetheinyl transferase; alpha-Aminoadipate reductase; L-Ornithine N-5-oxygenase; Siderophores; PKS; NRPS; Entomopathogen ID NONRIBOSOMAL PEPTIDE SYNTHETASES; ASPERGILLUS-FUMIGATUS; 4'-PHOSPHOPANTETHEINYL TRANSFERASE; SIDEROPHORE BIOSYNTHESIS; SACCHAROMYCES-CEREVISIAE; OXIDATIVE STRESS; CRYPTOCOCCUS-NEOFORMANS; ENTOMOPATHOGENIC FUNGI; PENICILLIN BIOSYNTHESIS; HISTOPLASMA-CAPSULATUM AB Based on genomic analysis, polyketide synthase (PKS) and nonribosomal peptide synthetase (NRPS) pathways account for biosynthesis of the majority of the secondary metabolites produced by the entomopathogenic fungus Metarhizium robertsii. To evaluate the contribution of these pathways to M. robertsii fitness and/or virulence, mutants deleted for mrpptA, the Sfp-type 4' phosphopantetheinyl transferase gene required for their activation were generated. Delta mrpptA strains were deficient in PKS and NRPS activity resulting in colonies that lacked the typical green pigment and failed to produce the nonribosomal peptides (destruxins, serinocylins, and the siderophores ferricrocin and metachelins) as well as the hybrid polyketide-peptides (NG-39x) that are all produced by the wild type (WT) M. robertsii. The Delta mrpptA colonies were also auxotrophic for lysine. Two other mutant strains were generated: Delta mraarA, in which the alpha-aminoadipate reductase gene critical for lysine biosynthesis was disrupted, and Delta mrsidA, in which the L-ornithine N-5-oxygenase gene that is critical for hydroxamate siderophore biosynthesis was disrupted. The phenotypes of these mutants were compared to those of Delta mrpptA to separate effects of the loss of lysine or siderophore production from the overall effect of losing all polyketide and non-ribosomal peptide production. Loss of lysine biosynthesis marginally increased resistance to H2O2 while it had little effect on the sensitivity to the cell wall disruptor sodium dodecyl sulfate (SDS) and no effect on sensitivity to iron deprivation. In contrast, combined loss of metachelin and ferricrocin through the inactivation of mrsidA resulted in mutants that were as hypersensitive or slightly more sensitive to H2O2, iron deprivation, and SDS, and were either identical or marginally higher in Delta mrpptA strains. In contrast to Delta mrpptA, loss of mrsidA did not completely abolish siderophore activity, which suggests the production of one or more non-hydroxamate iron-chelating compounds. Deletion of mrpptA, mrsidA, and mraarA reduced conidium production and conidia of a GFP-tagged Delta mrpptA strain displayed a longer germination delay than WT on insect cuticles, a deficiency that was rescued by lysine supplementation. Compared with WT, Delta mrpptA strains displayed 19-fold reduction in virulence against Drosophila suzukii. In contrast, lysine auxotrophy and loss of siderophores accounted for similar to 2 and similar to 6-fold decreases in virulence, respectively. Deletion of mrpptA had no significant effect on growth inhibition of Bacillus cereus. Our results suggest that PKS and NRPS metabolism plays a significant role in M. robertsii virulence, depresses conidium production, and contributes marginally to resistance to oxidative stress and iron homeostasis, but has no significant antibacterial effect.

We present a new version of the chicken genome assembly (Gallus_gallus-5.0; GCA_000002315.3), built from combined long single molecule sequencing technology, finished BACs, and improved physical maps. In overall assembled bases, we see a gain of 183 Mb, including 16.4 Mb in placed chromosomes with a corresponding gain in the percentage of intact repeat elements characterized. Of the 1.21 Gb genome, we include three previously missing autosomes, GGA30, 31, and 33, and improve sequence contig length 10-fold over the previous Gallus_gallus-4.0. Despite the significant base representation improvements made, 138 Mb of sequence is not yet located to chromosomes. When annotated for gene content, Gallus_gallus-5.0 shows an increase of 4679 annotated genes (2768 noncoding and 1911 protein-coding) over those in Gallus_gallus-4.0. We also revisited the question of what genes are missing in the avian lineage, as assessed by the highest quality avian genome assembly to date, and found that a large fraction of the original set of missing genes are still absent in sequenced bird species. Finally, our new data support a detailed map of MHC-B, encompassing two segments: one with a highly stable gene copy number and another in which the gene copy number is highly variable. The chicken model has been a critical resource for many other fields of study, and this new reference assembly will substantially further these efforts.

TI Genotyping-by-Sequencing-Based Investigation of the Genetic Architecture Responsible for a similar to Sevenfold Increase in Soybean Seed Stearic Acid SO G3-GENES GENOMES GENETICS LA English DT Article DE Glycine max; soybean; fatty acid composition; genotyping-by-sequencing; QTL mapping ID QUANTITATIVE TRAIT LOCI; FATTY-ACID; LINOLENIC ACID; OIL; QTL; MUTATIONS; IDENTIFICATION; ASSOCIATION; POPULATIONS; MAP AB Soybean oil is highly unsaturated but oxidatively unstable, rendering it nonideal for food applications. Until recently, the majority of soybean oil underwent partial chemical hydrogenation, which produces trans fats as an unavoidable consequence. Dietary intake of trans fats and most saturated fats are conclusively linked to negative impacts on cholesterol levels and cardiovascular health. Two major soybean oil breeding targets are: (1) to reduce or eliminate the need for chemical hydrogenation, and (2) to replace the functional properties of partially hydrogenated soybean oil. One potential solution is the elevation of seed stearic acid, a saturated fat which has no negative impacts on cardiovascular health, from 3 to 4% in typical cultivars to >20% of the seed oil. We performed QTL analysis of a population developed by crossing two mutant lines, one with a missense mutation affecting a stearoyl-acyl-carrier protein desaturase gene resulting in similar to 11% seed stearic acid crossed to another mutant, A6, which has 24-28% seed stearic acid. Genotyping-by-sequencing (GBS)-based QTL mapping identified 21 minor and major effect QTL for six seed oil related traits and plant height. The inheritance of a large genomic deletion affecting chromosome 14 is the basis for largest effect QTL, resulting in similar to 18% seed stearic acid. This deletion contains SACPD-C and another gene(s); loss of both genes boosts seed stearic acid levels to >= 18%. Unfortunately, this genomic deletion has been shown in previous studies to be inextricably correlated with reduced seed yield. Our results will help inform and guide ongoing breeding efforts to improve soybean oil oxidative stability.

Manure injection can conserve nitrogen (N) by decreasing ammonia (NH3) volatilization. However, the injection band also creates conditions that potentially favor nitrous oxide (N2O) production: an abundant organic substrate-promoting microbial activity, anaerobic conditions favoring denitrification, and large local concentrations of N. We assessed differences in NH3 volatilization and N2O emissions with broadcast application versus shallow disk injection of dairy slurry during the 2011 to 2013 growing seasons on a well-drained silt loam that received average manure-N application rates of 180 kg N ha(-1) via injection or 200 kg N ha(-1) via broadcast. Ammonia emissions were measured using a photoacoustic gas analyzer and chambers, and N2O emissions were measured using syringes to draw timed samples from vented chambers with analysis by gas chromatograph. Results point to a 92 to 98% (3.02-11.05 kg NH3-N ha(-1)) reduction in NH3 volatilization (for the initial sampling) with injection compared with broadcasting manure but also reveal 84 to 152% (725.9-3187.8 g N2O-N ha(-1)) greater cumulative N2O emissions. Although losses of N via N2O emission were at least three orders of magnitude less than NH3 volatilization, their potential role as a greenhouse gas is of concern. Despite the potential greenhouse gas trade-offs associated with shallow disk injection of manure, decreasing NH3 volatilization provides a substantial benefit, especially to farmers who are trying to conserve N and improve the N/P ratio of soil-applied manure.

SO JOURNAL OF ENVIRONMENTAL QUALITY LA English DT Review ID WATER-QUALITY; LONG-TERM; AGRICULTURAL PHOSPHORUS; RE-EUTROPHICATION; MAUMEE RIVER; MANAGEMENT; TRENDS; SOIL; OHIO; TRIBUTARIES AB Cumulative daily load time series show that the early 2000s marked a step-change increase in riverine soluble reactive phosphorus (SRP) loads entering the Western Lake Erie Basin from three major tributaries: the Maumee, Sandusky, and Raisin Rivers. These elevated SRP loads have been sustained over the last 12 yr. Empirical regression models were used to estimate the contributions from (i) increased runoff from changing weather and precipitation patterns and (ii) increased SRP delivery (the combined effects of increased source availability and/or increased transport efficiency of labile phosphorus [P] fractions). Approximately 65% of the SRP load increase after 2002 was attributable to increased SRP delivery, with higher runoff volumes accounting for the remaining 35%. Increased SRP delivery occurred concomitantly with declining watershed P budgets. However, within these watersheds, there have been long-term, largescale changes in land management: reduced tillage to minimize erosion and particulate P loss, and increased tile drainage to improve field operations and profitability. These practices can inadvertently increase labile P fractions at the soil surface and transmission of soluble P via subsurface drainage. Our findings suggest that changes in agricultural practices, including some conservation practices designed to reduce erosion and particulate P transport, may have had unintended, cumulative, and converging impacts contributing to the increased SRP loads, reaching a critical threshold around 2002.

One alternative to full manure containment systems is a vegetative treatment system (VTS) that collects runoff in a sediment basin and then applies it to a perennial vegetation (grass) treatment area that is harvested for hay. Little is known regarding the efficacy of large-scale commercial VTSs for the removal of microbial contaminants. In this study, an active, pump-based VTS designed and built for a 1200-head beef cattle feedlot operation was examined to determine the effects of repeated feedlot runoff application on fecal indicator microorganisms and pathogens over short-term (2 wk) and long-term (3 yr) operations and whether fecal bacteria were infiltrating into deeper soils within the treatment area. In a short-term study, fecal bacteria and pathogen numbers declined over time in soil. Measurements of total coliforms and Enterococcus counts taken on control soils were not effective as fecal indicators. The repeated application of manure-impacted runoff as irrigation water did not enrich the pathogens or fecal indicators in the soil, and no evidence was seen to indicate that pathogens were moving into the deeper soil at this site. These results indicate that large-scale, active VTSs reduce the potential for environmental contamination by manure-associated bacteria. Also, this study has implications to full-containment systems that apply runoff water to land application areas (cropland) and the fate of pathogens in the soils of land application sites.

Few studies have been conducted on the rates of E. coli transfer from streambed sediment to water column in low-flow conditions in natural streams. The aim of this work was to apply the watershed-scale model SWAT (Soil and Water Assessment Tool) to a natural stream to evaluate the need to account for the E. coli release from streambed sediments during baseflow periods and to compare the results of simulating such a release by assuming predominantly passive transport, driven by groundwater influx, against simulations assuming predominantly active transport of random or chemotaxis-driven bacteria movement. Escherichia coli concentrations in water during baseflow periods were substantially underestimated when E. coli release from the streambed was attributed only to streambed sediment resuspension. When considered in addition to the release due to sediment resuspension at high flows, the active and passive release assumptions provided 42 and 4% improvement, respectively, in the RMSE of logarithms of E. coli concentrations. Estimated E. coli fluxes to water column during the baseflow periods from June to November ranged from 3.3 x 105 colony-forming units (CFU) m(-2) d(-1) in the game land area to 1.4 x 10(6) CFU m(-2) d(-1) in the mixed pasture and cropland. Results demonstrate that release of E. coli from streambed sediments during baseflow periods is substantial and that water column E. coli concentrations are dependent on not only land management practices but also on in-stream processes.

Evidence from an initial study indicated that treatment of layer hen manure with 12mM nitroethane decreased populations of generic E. coli and total coliforms by 0.7 and 2.2 log(10) colony forming units (CFU) g(-1), respectively, after 24h aerobic incubation at ambient temperature when compared to untreated populations. Salmonella concentrations were unaffected by nitroethane in this study. In a follow-up experiment, treatment of 6-month-old layer hen litter (mixed with 0.4mL water g(-1)) with 44mM 2-nitroethanol, 2-nitropropanol or ethyl nitroacetate decreased an inoculated Salmonella typhimurium strain from its initial concentration (3 log(10) CFU g(-1)) by 0.7 to 1.7 log(10) CFU g(-1) after 6h incubation at 37 degrees C in covered containers. After 24h incubation, populations of the inoculated S. Typhmiurium in litter treated with 44mM 2-nitroethanol, 2-nitropropanol, ethyl nitroacetate or nitroethane were decreased more than 3.2 log(10) CFU g(-1) compared to populations in untreated control litter. Treatment of litter with 44mM 2-nitroethanol, 2-nitropropanol, ethyl nitroacetate decreased rates of ammonia accumulation more than 70% compared to untreated controls (0.167 mu mol mL(-1) h(-1)) and loses of uric acid (< 1 mu mol mL(-1)) were observed only in litter treated with 44mM 2-nitropropanol, indicating that some of these nitrocompounds may help prevent loss of nitrogen in treated litter. Results warrant further research to determine if these nitrocompounds can be developed into an environmentally sustainable and safe strategy to eliminate pathogens from poultry litter, while preserving its nitrogen content as a nutritionally valuable crude protein source for ruminants.

In these temperate ecosystems, large ungulates are prevalent and coyote pack size may be large in order for them to scavenge and defend ungulate carcasses from conspecifics in neighboring packs. We initiated a study to understand the spatial and social ecology of coyotes on the Valles Caldera National Preserve, a high-elevation (2450-3400 m) protected area in northern New Mexico. Our objectives were to (1) describe the home range size and habitat use of coyotes in the preserve, (2) describe coyote movements within and outside of packs, and (3) to evaluate the relationship between coyote social cohesion and the amount of elk (Cervus elaphus) in the coyote diet. We acquired global positioning system and telemetry locations from 33 coyotes from August 2005 to July 2009. We classified 23 coyotes (70 % of individuals) as residents (i.e., territorial) during at least part of the study and ten coyotes (30 %) as transients. Overall mean home range size of resident packs was 10.6 +/- 2.2 (SD) km(2). Home range size varied between packs, but did not vary by season or year. Coyotes used dry and wet meadow habitats as expected based on availability; coyotes used riparian habitat more than expected, and forests less than expected. Social cohesion did not vary among biological seasons. Alpha coyotes were more socially cohesive with each other than with other pack members, and a transient exhibited temporal-spatial avoidance of pack members while inside the pack's territory followed by integration into the pack. Contrary to expectations, we found no relationship between coyote social cohesion and the proportion of elk in coyote diets. We concluded that coyote space use and sociality on the preserve were relatively stable year-round despite changes in biological needs, snow depth, and utilization of variously sized prey.

Results showed that PBC-FAs were a potent antimicrobial against gram-positive bacteria with MICs of 1.8 to 3.6 mu g/ml. The compounds were less effective against gram-negative bacteria. Derivatives of PBC-FAs and an equimolar mixture of oleic acid and phenol all had MICs above 233 mu g/ml against both gram-positive and gram-negative bacteria. Comparison of antimicrobial activities of the PBC-FAs with those of the derivatives suggests that the carboxylic group in the fatty acid moiety and the hydroxyl group on the phenol moiety were responsible for the antimicrobial efficacy. Growth curves of L. innocua revealed that PBC-FAs prevented bacterial growth, while MBC-FAs only delayed the onset of rapid growth of L. innocua. Our results demonstrated that the novel PBC-FAs have potential for use as antimicrobials against gram-positive bacteria. C1 [Fan, Xuetong; Wagner, Karen; Sokorai, Kimberly J.

This is ideally followed by strain typing, which provides information critical to the investigation of outbreaks and the attribution of their sources. Pulsed-field gel electrophoresis is the "gold standard'' for S. enterica strain typing, but its limitations have encouraged the search for alternative methods, including whole genome sequencing. Both methods typically require a pure culture, which adds to the cost and turnaround time. A more rapid and cost-effective method with sufficient discriminatory power would benefit food industries, regulatory agencies, and public health laboratories. To address this need, a novel enrichment, amplification, and sequence-based typing (EAST) approach was developed involving (i) overnight enrichment and total DNA preparation, (ii) amplification of polymorphic tandem repeatcontaining loci with electrophoretic detection, and (iii) DNA sequencing and bioinformatic analysis to identify related strains. EAST requires 3 days or less and provides a strain resolution that exceeds serotyping and is comparable to pulsed-field gel electrophoresis. Evaluation with spiked ground turkey demonstrated its sensitivity (with a starting inoculum of <= 1 CFU/g) and specificity (with unique or nearly unique alleles relative to databases of.1,000 strains). In tests with unspiked retail chicken parts, 3 of 11 samples yielded S. enterica-specific PCR products. Sequence analysis of three distinct typing targets (SeMT1, SeCRISPR1, and SeCRISPR2) revealed consistent similarities to specific serotype Schwarzengrund, Montevideo, and Typhimurium strains. EAST provides a time-saving and cost-effective approach for detecting and typing foodborne S. enterica, and postenrichment steps can be commercially outsourced to facilitate its implementation. Initial studies with Listeria monocytogenes and Shiga toxigenic Escherichia coli suggest that EAST can be extended to these foodborne pathogens.

Effects investigated included the color, carbon dioxide (CO2) generation, weight loss, and surface morphology of the lettuce during storage. Romaine lettuce pieces, with or without inoculation with a cocktail of three strains of E. coli O157: H7 (similar to 6 log CFU/g of lettuce), were packaged in a polyethylene terephthalate commercial clamshell container and treated at 34.8 kV at 1.1 kHz for 5 min by using a DACP treatment system equipped with a pin-type high-voltage electrode. Romaine lettuce samples were analyzed for inactivation of E. coli O157: H7, total mesophilic aerobes, and yeasts and molds, color, CO2 generation, weight loss, and surface morphology during storage at 4 degrees C for 7 days. The DACP treatment reduced the initial counts of E. coli O157: H7 and total aerobic microorganisms by similar to 1 log CFU/g, with negligible temperature change from 24.5 +/- 6 1.4 degrees C to 26.6 +/- 1.7 degrees C. The reductions in the numbers of E. coli O157: H7, total mesophilic aerobes, and yeasts and molds during storage were 0.8 to 1.5, 0.7 to 1.9, and 0.9 to 1.7 log CFU/g, respectively. DACP treatment, however, did not significantly affect the color, CO2 generation, weight, and surface morphology of lettuce during storage (P>0.05). Some mesophilic aerobic bacteria were sublethally injured by DACP treatment. The results from this study demonstrate the potential of applying DACP as a postpackaging treatment to decontaminate lettuce contained in conventional plastic packages without altering color and leaf respiration during posttreatment cold storage.

TI Neural Network Model for Thermal Inactivation of Salmonella Typhimurium to Elimination in Ground Chicken: Acquisition of Data by Whole Sample Enrichment, Miniature Most-Probable-Number Method SO JOURNAL OF FOOD PROTECTION LA English DT Article DE Ground chicken; Neural network model; Predictive microbiology; Salmonella Typhimurium; Thermal inactivation; Whole sample enrichment; miniature most-probable-number method ID LISTERIA-MONOCYTOGENES; MEAT; SEROTYPES; POULTRY; CINNAMALDEHYDE; CARVACROL; SURVIVAL; PATTIES; GROWTH; THIGH AB Predictive models are valuable tools for assessing food safety. Existing thermal inactivation models for Salmonella and ground chicken do not provide predictions above 71 degrees C, which is below the recommended final cooked temperature of 73.9 degrees C for chicken. They also do not predict when all Salmonella are eliminated without extrapolating beyond the data used to develop them. Thus, a study was undertaken to develop a model for thermal inactivation of Salmonella to elimination in ground chicken at temperatures above those of existing models. Ground chicken thigh portions (0.76 cm(3)) in microcentrifuge tubes were inoculated with 4.45 +/- 0.25 log most probable number (MPN) of a single strain of Salmonella Typhimurium (chicken isolate). They were cooked at 50 to 100 degrees C in 2 or 2.5 degrees C increments in a heating block that simulated two-sided pan frying. A whole sample enrichment, miniature MPN (WSE-mMPN) method was used for enumeration. The lower limit of detection was one Salmonella cell per portion. MPN data were used to develop a multiple-layer feedforward neural network model. Model performance was evaluated using the acceptable prediction zone (APZ) method. The proportion of residuals in an APZ (pAPZ) from -1 log (fail-safe) to 0.5 log (fail-dangerous) was 0.911 (379 of 416) for dependent data and 0.910 (162 of 178) for independent data for interpolation. A pAPZ >= 0.7 indicated that model predictions had acceptable bias and accuracy. There were no local prediction problems because pAPZ for individual thermal inactivation curves ranged from 0.813 to 1.000. Independent data for interpolation satisfied the test data criteria of the APZ method. Thus, the model was successfully validated. Predicted times for a 1-log reduction ranged from 9.6 min at 56 degrees C to 0.71 min at 100 degrees C. Predicted times for elimination ranged from 8.6 min at 60 degrees C to 1.4 min at 100 degrees C. The model will be a valuable new tool for predicting and managing this important risk to public health. C1 [Oscar, T.

The U.S. Department of Agriculture, Food Safety and Inspection Service has identified a higher percentage of non-O157 EHEC compared with E. coli O157:H7-positive samples collected from veal trimmings than from products produced from other cattle slaughter classes. Therefore samples were collected from hides and preevisceration carcasses at five veal processors to assess E. coli O157:H7 and non-O157 EHEC contamination during bob veal and formula-fed veal dressing procedures. E. coli O157:H7 prevalence was measured by culture isolation and found to be on 20.3% of hides and 6.7% of carcasses. In contrast, a non-O157 EHEC molecular screening assay identified 90.3% of hides and 68.2% of carcasses as positive. Only carcass samples were taken forward to culture confirmation and 38.7% yielded one or more non-O157 EHEC isolates. The recovery of an EHEC varied by plant and sample collection date; values ranged from 2.1 to 87.8% among plants and from 4.2 to 64.2% within the same plant. Three plants were resampled after changes were made to sanitary dressing procedures. Between the two collection times at the three plants, hide-to-carcass transfer of E. coli O157:H7 and non-O157 EHEC was significantly reduced. All adulterant EHEC serogroups (O26, O45, O103, O111, O121, and O145) were isolated from veal carcasses as well as four other potentially pathogenic serogroups (O5, O84, O118, and O177). Bob veal was found to have a greater culture prevalence of E. coli O157:H7 and greater positive molecular screens for non-O157 EHEC than formula-fed veal (P < 0.05), but the percentage of culture-confirmed non-O157 EHEC was not different (P > 0.05) between the two types of calves. EHEC-O26, -O111, and -O121 were found more often in bob veal (P < 0.05), whereas EHEC-O103 was found more often in formula-fed veal (P < 0.05).

This paper synthesizes the much-needed state of-knowledge on the effects of tillage, crop residue, and nutrient management practices on SOC sequestration and identifies potential research gap, opportunities, and challenges in studying SOC dynamics in rice (Otyza sativa L.)-based cropping systems in South Asia, mainly in Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka. Improved management practices such as reduced- and no-tillage management, nitrogen (N) fertilizer and farmyard manure (FYM) application, and crop residue addition can improve SOC accumulation. Positive effects of no-tillage, crop residue addition, N addition through manure or compost application, and integration of organic and chemical fertilizers on SOC accumulation in rice -based cropping systems have been documented from South Asia. However, limited data and enormous discrepancies in SOC measurements across the region exist as the greatest challenge in increasing SOC sequestration and improving agricultural sustainability. More research on SOC as influenced by alternative tillage, crop residue, and nutrient management systems, and development of SOC monitoring system for existing long-term experiments will advance our understanding of the SOC dynamics in rice -based cropping systems and improve agricultural system sustainability in South Asia.

This study aims to characterize the lipid mediator profile including oxygenated lipids, endocannabinoids, and ceramides/sphingoid bases in sweat and identify differences in these profiles between sweat collected from nonlesional sites on the unflared volar forearm of subjects with and without atopic dermatitis (AD). Adapting routine procedures developed for plasma analysis, over 100 lipid mediators were profiled using LC-MS/MS and 58 lipid mediators were detected in sweat. Lipid mediator concentrations were not affected by sampling or storage conditions. Increases in concentrations of C30-C40 [NS] and [NdS] ceramides, and C18:1 sphingosine, were observed in the sweat of study participants with AD despite no differences being observed in transepidermal water loss between study groups, and this effect was strongest in men (P < 0.05, one-way ANOVA with Tukey's post hoc HSD). No differences in oxylipins and endocannabinoids were observed between study groups.(Jlr) Sweat mediator profiling may therefore provide a noninvasive diagnostic for AD prior to the presentation of clinical signs.

Beetles were exposed for 60,120, and 180 min, and 1, 3 and 5 days on the same treatment arenas, and after the 5 d interval the insects were removed and placed in untreated arenas for 5 more days. All Trogoderma variable (Ballion), the warehouse beetle, Prostephanus truncatus (Horn), the larger grain borer, Rhyzopertha dominica (F.), the lesser grain borer, and Tribolium castaneum (Herbst), the red flour beetle, were knocked down on the outside and inside surfaces of the bag after one hour of exposure. Mortality of T. variable, P. truncatus, and R dominica increased during the exposure period, with generally lower mortality on the inside versus the outside of the bag after either 3 or 5 days of continual exposure. However, maximum mortality of T. castaneum, the red flour beetle, was only 5.6 +/- 3.4% after 5 days of exposure. While it took longer for 100% knockdown of Sitophilus oryzae (L), the rice weevil, compared to the above species, all S. oryzae were dead after 5 d of exposure on both surfaces. In contrast, after 5 days knockdown of Sitophilus zeamais (Motschlulsky), the maize weevil, did not exceed 30% and there was no mortality. After the Sitophilus species were transferred to untreated arenas, knockdown of all species decreased and mortality increased, indicating delayed mortality add no recovery from knockdown. Mortality of Dermestes maculatus (DeGeer), the hide beetle, did not exceed 5.6% at any time and there was no delayed mortality, indicating a potential tolerance of this particular strain of D. maculatus used in the study. Our results show that the ZeroFly (R) Storage Bags could effectively limit penetration of stored-product beetles through the bag into stored grains or milled grain products. (C) 2016 Elsevier Ltd.

TI Detection of internally infested popcorn using electrically conductive roller mills SO JOURNAL OF STORED PRODUCTS RESEARCH LA English DT Article DE Infestation; Detection; X-ray; Maize weevil ID WEEVIL SITOPHILUS-GRANARIUS; X-RAY; WHEAT; INFESTATION; GRAIN; L.; INSECTS AB To detect popcorn kernels infested by the internal feeding stored-product insect pest Sitophilus zeamais, maize weevil, a laboratory roller mill was modified so that the electrical conductivity of the grain is measured while the kernels are milled between the rolls. When a kernel with a S. zeamais larvae inside is milled, the moisture from the crushed insect abruptly changes the conductivity of the test circuit. The objective of this study was to determine the potential of the modified conductance mill to detect popcorn infested with different developmental stages. Two laboratory milling units were tested that had differing sharpness, which affected the feed-rate through the rolls. One mill averaged 135 s to feed 1 kg of popcorn while the second mill with sharper teeth averaged 100 s to feed 1 kg of popcorn. Four popcorn varieties were evaluated, with their average kernel weight ranging from 12.5 g to 18.5 g per 100 kernels. Known numbers of infested popcorn kernels were added to 1 kg samples of popcorn. The slower feeding mill detected 81% of the pupae, 91% of the medium larvae, and 47% of the small larvae. The faster feeding mill detected 75% of the pupae, 80% of the medium larvae, and 43% of the small larvae. Our results indicate that the conductance mill is a good method for quickly evaluating popcorn samples for kernels infested with late stage larvae and pupae. Published by Elsevier Ltd.

TI Field evaluation of the long-lasting treated storage bag, deltamethrin incorporated, (ZeroFly (R) Storage Bag) as a barrier to insect pest infestation SO JOURNAL OF STORED PRODUCTS RESEARCH LA English DT Article DE Bagged grain; Stored-product insect; Maize; Ghana ID SUB-SAHARAN AFRICA; POSTHARVEST LOSSES; STORED WHEAT; MAIZE; GRAINS; WEST AB The deltamethrin incorporated polypropylene (PP) bag, ZeroFly (R) Storage Bag, is a new technology to reduce postharvest losses caused by stored-product insect pests. Maize was pre-fumigated and used for the following treatments: ZeroFly (R) bags filled with untreated maize, PP bags filled with maize treated with Betallic Super (80 g pirimiphos-methyl and 15 g permethrin per liter as an emulsifiable concentrate (EC)), and PP bags filled with untreated maize (control). The experiment was conducted from February -August 2015, at four sites in different locations of the Middle Belt of Ghana. Moisture content (MC), number of live and dead insects, insect damaged kernels (IDK) and maize weight loss data were collected monthly. ZeroFly (R) bags and Betallic treatment significantly reduced insect damage compared to the control treatment. ZeroFly (R) bags were able to keep IDK levels below 5% for 4 months, but the levels increased to 5.2 and 10.2% by 5 and 6 months of storage, respectively. In the control, IDK increased significantly over time and reached 32% after 6 months. The ZeroFly (R) bag was effective against Sitophilus, Tribolium and Cryptolestes species for 4 months. Mean weight loss of <3.68% was recorded in ZeroFly (R) bags during 6 months of storage whereas 11.88% weight loss occurred in the PP bags by 6 months of storage. Based on our results, ZeroFly (R) bags were found to have potential for use in the reduction of postharvest grain losses in bagged grains. Maize may still have been infested during bagging hence ZeroFly (R) bags were effective for storage for only 4 months. However, greater benefits of using ZeroFly (R) bags are realized if insect-free grains or legumes are stored in bags. (C) 2016 Elsevier Ltd. All rights reserved.

Efforts have been made in the US to eradicate the disease in cattle, but spillover into wildlife and subsequent spillback have impeded progress in some states. In particular, infection in white-tailed deer (Odocoileus virginianus) has been followed by infection in cattle in some Midwestern states. Infection has also been documented in feral swine (Sus scrofa) on the Hawaiian island of Molokai and in various European countries, but no large-scale survey of antibody exposure to the bacteria has been conducted in feral swine in the US. We tested 488 sera from feral swine collected near previously documented outbreaks of bovine tuberculosis in cattle and captive cervids, in addition to 2,237 feral swine sera collected across the US from 1 October 2013 to 30 September 2014. While all but one of the samples were antibody negative, the results are important for establishing baseline negative data since feral swine are capable reservoirs and could be implicated in future outbreaks of the disease.

TI PREVALENCE AND DISTRIBUTION OF WELLFLEET BAY VIRUS EXPOSURE IN THE COMMON EIDER (SOMATERIA MOLLISSIMA) SO JOURNAL OF WILDLIFE DISEASES LA English DT Article DE Common Eider; serology; seroprevalence; Wellfleet Bay virus AB Between 1998 and 2014, recurrent mortality events were reported in the Dresser's subspecies of the Common Eider (Somateria mollissima dresseri) on Cape Cod, Massachusetts, US near Wellfleet Harbor. The early die-offs were attributed to parasitism and emaciation, but beginning in 2006 a suite of distinct lesions was observed concomitant with the isolation of a previously unknown RNA virus. This novel pathogen was identified as an orthomyxovirus in the genus Quaranjavirus and was named Wellfleet Bay virus (WFBV). To assess evidence of exposure to this virus in Common Eiders, we conducted a longitudinal study of the prevalence of WFBV antibodies at multiple locations from 2004-14; we collected 2,258 serum samples from six locations and analyzed each using a microneutralization assay. Results corroborate the emergence of WFBV in 2006 based on the first detection of antibodies in that year. Significantly higher prevalence was detected in Common Eiders sampled in Massachusetts compared to those in Maine, Nova Scotia, and Que ' bec. For birds breeding and wintering in Massachusetss, viral exposure varied by age, sex, and season of sampling, and prevalence by season and sex were highly interrelated with greater numbers of antibody-positive males in the autumn and females in the spring. No evidence of viral exposure was detected in the Northern subspecies (Somateria mollissima borealis). Among the locations sampled, Massachusetts appears to be the epicenter of Common Eider exposure to WFBV. Further research is warranted to understand the factors controlling the epidemiology of WFBV in Massachussetts, including those that may be limiting geographic expansion of this virus.

Antemortem and gross pathology findings included muscle atrophy, marked weight loss, and bilaterally symmetric alopecia with hyperpigmentation and crusting over the face, medial surfaces of the pinnae, dorsal trunk, distal limbs, perineal area, and tail. Histologically, the skin lesions were characterized by granulomatous mural folliculitis with numerous multinucleated giant cells and fewer lymphocytes and eosinophils consistent with previous reports of chronic ovine herpesvirus-2 (OvHV-2) infection. Multiple skin samples were positive for OvHV-2 DNA on PCR, and on partial sequencing of the viral DNA, there was 94% homology with reference GenBank OvHV-2. Quantitative PCR confirmed an increased level of OvHV-2 DNA in the lesional skin tissues. Based on exclusion of other disease processes, gross and histological lesions, PCR, and viral DNA sequencing results, a diagnosis of OvHV-2-mediated malignant catarrhal fever-like dermatitis was made.

TI Effects of land use on population presence and genetic structure of an amphibian in an agricultural landscape SO LANDSCAPE ECOLOGY LA English DT Article DE Dispersal; Landscape genetics; Focal patch; Species distribution; Functional connectivity ID ACRIS-CREPITANS-BLANCHARDI; LINEAR MIXED MODELS; FRAGMENTED LANDSCAPE; CONSERVATION; CONNECTIVITY; DISPERSAL; HABITAT; BIODIVERSITY; RESISTANCE; SOFTWARE AB Species distributions are a function of an individual's ability to disperse to and colonize habitat patches. These processes depend upon landscape configuration and composition. Using Blanchard's cricket frogs (Acris blanchardi), we assessed which land cover types were predictive of (1) presence at three spatial scales (pond-shed, 500 and 2500 m) and (2) genetic structure. We predicted that forested, urban, and road land covers would negatively affect cricket frogs. We also predicted that agricultural, field, and aquatic land covers would positively affect cricket frogs. We surveyed for cricket frogs at 28 sites in southwestern Ohio, USA to determine presence across different habitats and analyze genetic structure among populations. For our first objective, we examined if land use (crop, field, forest, and urban habitat) and landscape features (ponds, streams, and roads) explained presence; for our second objective, we assessed whether these land cover types explained genetic distance between populations. Land cover did not have a strong influence on cricket frog presence. However, multiple competing models suggested effects of roads, streams, and land use. We found genetic structuring: populations were grouped into five major clusters and nine finer-scale clusters. Highways were predictive of increased genetic distance. By combining a focal-patch study with landscape genetics, our study suggests that major roads and waterways are key features affecting species distributions in agricultural landscapes. We demonstrate that cricket frogs may respond to landscape features at larger spatial scales, and that presence and movement may be affected by different environmental factors.

TI Climate change and ecosystem composition across large landscapes SO LANDSCAPE ECOLOGY LA English DT Article DE Terrestrial ecosystems; Climate change; Vegetation composition; Large area landscapes; Southwest USA; Bioclimate ID BIODIVERSITY; PROJECTIONS; GRADIENTS; RESPONSES; SPACE; TIME AB Climate change alters the vegetation composition and functioning of ecosystems. Measuring the magnitude, direction, and rate of changes in vegetation composition induced by climate remains a serious and unmet challenge. Such information is required for a predictive capability of how individual ecosystem will respond to future climates. Our objectives were to identify the relationships between 20 climate variables and 39 ecosystems across the southwestern USA. We sought to understand the magnitude of relationships between variation in vegetation composition and bioclimatic variables as well as the amount of ecosystem area expected to be affected by future climate changes. Bioclimatic variables best explaining the plant species composition of each ecosystem were identified. The strength of relationships between beta turnover and bioclimate gradients was calculated, the spatial concordance of ecosystem and bioclimate configurations was shown, and the area of suitable climate remaining within the boundaries of contemporary ecosystems under future climate projections was measured. Across the southwestern USA, four climate variables account for most of the climate related variation in vegetation composition. Twelve ecosystems are highly sensitive to climate change. By 2070, two ecosystems lose about 4000 (15 %) and 7000 (31 %) km(2) of suitable climate area within their current boundaries (the Western Great Plains Sandhill Steppe and Sonora-Mojave Creosotebush-White Bursage Desert Scrub ecosystems, respectively). The climatic areas of riparian ecosystems are expected to be reduced by half. Results provide specific climate and vegetation parameters for anticipating how, where and when ecosystem vegetation transforms with climate change. Projecting the loss of suitable climate for the vegetation composition of ecosystems is important for assessing ecosystem threats from climate change and for setting priorities for ecosystem conservation and restoration across the southwestern USA.

The objective of this study was to determine parent feeding strategies used to influence child acceptance of previously rejected foods (PRF). Methods We conducted eighteen focus groups (total participants = 111) with low-income African American and Hispanic parents of preschool children (3- to 5-year-olds) in Texas, Colorado, and Washington. Through thematic analysis, we coded transcripts and analyzed coded quotes to develop dominant emergent themes related to strategies used to overcome children's food refusal. Results We found three major themes in the data: parents most often do not serve PRF; parents value their child eating over liking a food; and parents rarely use the same feeding strategy more than once for a PRF. Desiring to reduce waste and save time, parents said they most often intentionally decided not to purchase or serve PRF to their children. Discussion Because parents' primary goal in child feeding is getting children to eat (over acceptance of a variety of foods), strategies to help parents promote consumption of less easily accepted foods could help parents with child feeding struggles and improve children's dietary quality.

TI Trends in Weight-for-Length Among Infants in WIC From 2000 to 2014 SO PEDIATRICS LA English DT Article ID SUPPLEMENTAL NUTRITION PROGRAM; UNITED-STATES; CHILDHOOD OBESITY; GROWTH CHARTS; CHILDREN; PREVALENCE; OVERWEIGHT; FOOD; ADOLESCENTS; PACKAGE AB OBJECTIVES: To describe the prevalence and secular trends of high weight-for-length among infants (ages, 3-23 months) in the biennial US Department of Agriculture Women, Infants, and Children Program and Participants Characteristic (WIC-PC) Survey from 2000 through 2014 (n = 16 927 120). METHODS: Weight-for-length was considered to be "high" if it was >= 2 SDs above the sex-and age-specific median in the World Health Organization growth standards. Poisson regression was used to calculate adjusted prevalence ratios. RESULTS: The overall prevalence of high weight-for-length increased from 13.4% in 2000 to 14.5% in 2004, remained constant until 2010, and then decreased by >2 percentage points (to 12.3%) through 2014. The prevalence of high weight-for-length was associated with sex (higher among boys), race-ethnicity (highest among American Indians/ Alaskan Natives), and with both age (positive) and family income (inverse). The secular trends, however, were fairly similar within categories of these variables. From 2010 to 2014, the prevalence of high weight-for-length decreased in 40 states and 3 (of 5) US territories, with the largest decreases seen in Puerto Rico (-9 percentage points) and Kentucky (-7 percentage points), and the largest increase (+2 percentage points) seen in West Virginia. CONCLUSIONS: Although the current results cannot be considered representative of infants in the populations, the prevalence of a high weight-for-length has decreased among infants in WIC-PC since 2010. These decreases were similar across categories of most characteristics, but there were substantial differences across jurisdictions, possibly reflecting differences in policy and local programs that target maternal and infant health.

Locomotion involves physical activity, which can have far-reaching effects on physiology and neurobiology, both acutely and chronically. In human populations and in laboratory rodents, higher levels of physical activity are generally associated with positive health outcomes, although excessive exercise can have adverse consequences. Whether and how such relationships occur in wild animals is unknown. Behavioral variation among individuals arises from genetic and environmental factors and their interactions as well as from developmental programming (persistent effects of early-life environment). Although tremendous progress has been made in identifying genetic and environmental influences on individual differences in behavior, early-life effects are not well understood. Early-life effects can in some cases persist across multiple generations following a single exposure and, in principle, may constrain or facilitate the rate of evolution at multiple levels of biological organization. Understanding the mechanisms of such transgenerational effects (e.g., exposure to stress hormones in utero, inherited epigenetic alterations) may prove crucial to explaining unexpected and/or sex-specific responses to selection as well as limits to adaptation. One area receiving increased attention is early-life effects on adult physical activity. Correlational data from epidemiological studies suggest that early-life nutritional stress can (adversely) affect adult human activity levels and associated physiological traits (e.g., body composition, metabolic health). The few existing studies of laboratory rodents demonstrate that both maternal and early-life exercise can affect adult levels of physical activity and related phenotypes. Going forward, rodents offer many opportunities for experimental studies of (multigenerational) early-life effects, including studies that use maternal exposures and cross-fostering designs.

Island Press, Washington, DC, 2005), and in sub-Saharan Africa specifically, 70% of rangelands are considered moderately to severely degraded (UNCCD 1994). Given that these drylands make up 43% of Africa's land area and support approximately 45% of its population, restoring, maintaining and even increasing their productivity is imperative from both conservation and food security standpoints. In the Laikipia and Samburu counties of Kenya, degradation manifests itself through the increase of bare ground and the replacement of perennial grasses by undesirable plant species, primarily Acacia reficiens and Opuntia stricta, resulting in reduced forage availability. Further complicating management is the fact that most land in this ecosystem is owned by community conservancies, where the land is managed to support both wildlife and livestock grazing. There has been considerable effort targeted towards using mechanical clearing coupled with reseeding to combat A. reficiens spread. Additionally, the use of both traditional and modern mobile cattle enclosures (commonly referred to as bomas) has been used to create vegetation patches in areas with increasing bare ground. Here, we look at the challenges faced in implementing these interventions, as well as the successes and opportunities associated with them.

TI Social-ecological dynamics of change and restoration attempts in the Chihuahuan Desert grasslands of Janos Biosphere Reserve, Mexico SO PLANT ECOLOGY LA English DT Article DE Land use change; Shrub encroachment; Ejido; Grazing; Restoration; Mexico ID LAND DEGRADATION; FIRE; MANAGEMENT; SOUTHWEST; ECOSYSTEM; LIVESTOCK; WOODLAND; MESQUITE; SAVANNA; USA AB Shrub encroachment and declining grass production are widespread throughout the grasslands and savannas of the Mexico-US borderlands, with negative consequences for ecosystem services, livestock production, and native biodiversity. The problem suggests a complex interaction of social and ecological drivers that are not well understood. Using the Chihuahuan Desert grasslands of the Janos Biosphere Reserve of northern Mexico as a case study, we sought to understand the social-ecological context that shaped landscape change. Our approach included a synthesis of the historical literature and interviews with local residents, with the goal of facilitating long-term grassland restoration. Findings indicate that recent changes in Chihuahuan Desert grasslands are likely related to the co-occurrence of heavy grazing, fire suppression, and the elimination of key species, including prairie dogs and native ungulates. Local residents widely perceive both fire and prairie dogs to be destructive to grasslands and livelihoods. Over the last 50 years, evolving land tenure policies have fragmented the landscape into smaller parcels which typically produce an insufficient livelihood from cattle despite high stocking rates. Declining cattle profitability has motivated the sale and conversion of rangelands to more profitable croplands irrigated with groundwater. Since the founding of the Janos Biosphere Reserve in 2009, universities, local cattle operators, conservation organizations, and federal agencies have begun collaborating on restoration activities. While complete restoration of grasslands is unlikely, progress appears possible largely because of the willingness of local residents to try new management practices that may improve their ability to benefit from the land.

The region experienced high levels of ecological disturbance during the early period of Euro-American settlement, especially from about 1870-1935. The principal plant communities of the Great Basin are sagebrush steppes, dominated by various Artemisia shrubs and perennial bunchgrasses that represent the largest rangeland ecosystem in North America. In low to mid-elevation sagebrush communities, exotic annual grasses have displaced native plant species and are associated with a dramatic increase in size and frequency of wildfires. Degradation in this region is driven by processes that cause the loss of mature bunchgrasses, which, when intact, limit exotic annual grass invasion. Historically, large economic investments to restore degraded Great Basin rangeland through establishment of native bunchgrasses, principally utilizing heavily mechanized agronomic approaches, have been met with limited success. A multitude of environmental factors contribute to the lack of restoration success in this region, but seedling mortality from freezing and drought has been identified as a primary demographic limitation to successful bunchgrass establishment. Novel approaches to overcoming limitations to bunchgrass establishment will be required for restoration success. Increased national concern and a near listing of the greater sage-grouse, a steppe-obligate species, to Endangered Species status, has spurred greater regional support and collaboration across a diversity of stakeholder groups such as state and federal land and wildlife management agencies, county planners, and ranchers.

TI Mapping Tree Canopy Cover in Support of Proactive Prairie Grouse Conservation in Western North America SO RANGELAND ECOLOGY & MANAGEMENT LA English DT Article DE eastern redcedar; encroachment; juniper; lesser prairie-chicken; mesquite; remote sensing; sage grouse ID GREATER SAGE-GROUSE; ELEVATION SAGEBRUSH STEPPE; JUNIPER ENCROACHMENT; NEW-MEXICO; VEGETATIVE COMMUNITIES; HERBACEOUS BIOMASS; HABITAT SELECTION; MESQUITE CONTROL; PRESCRIBED FIRE; BLUE MOUNTAINS AB Invasive woody plant expansion is a primary threat driving fragmentation and loss of sagebrush (Artemisia spp.) and prairie habitats across the central and western United States. Expansion of native woody plants, including conifer (primarily Juniperus spp.) and mesquite (Prosopis spp.), over the past century is primarily attributable to wildfire suppression, historic periods of intensive livestock grazing, and changes in climate. To guide successful conservation programs aimed at reducing top-down stressors, we mapped invasive woody plants at regional scales to evaluate landscape level impacts, target restoration actions, and monitor restoration outcomes. Our overarching goal was to produce seamless regional products across sociopolitical boundaries with resolution fine enough to depict the spatial extent and degree of woody plant invasion relevant to greater sage-grouse (Centrocercus urophasianus) and lesser prairie-chicken (Tympanuchus pallidicinctus) conservation efforts. We mapped tree canopy cover at 1-m spatial resolution across an 11-state region (508 265 km(2)). Greater than 90% of occupied lesser prairie-chicken habitat was largely treeless for conifers (<1% canopy cover), whereas > 67% was treeless for mesquite. Conifers in the higher canopy cover classes (16-50% and >50% canopy cover) were scarce (<2% and 1% canopy cover), as was mesquite (<5% and 1% canopy cover). Occupied habitat by sage-grouse was more variable but also had a relatively large proportion of treeless areas ((x) over bar = 71, SE = 5%). Low to moderate levels of conifer cover (1-20%) were fewer ((x) over bar = 23, SE = 5%) as were areas in the highest cover class (>50%; (x) over bar = 6, SE = 2%). Mapping indicated that a high proportion of invading woody plants are at a low to intermediate level. Canopy cover maps for conifer and mesquite resulting from this study provide the first and most geographically complete, high-resolution assessment of woody plant cover as a top-down threat to western sage-steppe and prairie ecosystems.

Using a before-after-control-impact design, we evaluated short-term effects of conifer removal on nesting habitat use by monitoring 262 sage-grouse nests in the northern Great Basin during 2010-2014. Tree removal made available for nesting an additional 28% of the treatment landscape by expanding habitat an estimated 9603 ha (3201 ha [+/- 480 SE] annually). Relative probability of nesting in newly restored sites increased by 22% annually, and females were 43% more likely to nest within 1000 m of treatments. From 2011 (pretreatment) to 2014 (3 yr after treatments began), 29% of the marked population (9.5% [+/- 1.2 SE] annually) had shifted its nesting activities into mountain big sagebrush habitats that were cleared of encroaching conifer. Grouping treatments likely contributed to beneficial outcomes for grouse as individual removal projects averaged just 87 ha in size but cumulatively covered a fifth of the study area. Collaboratively identifying future priority watersheds and implementing treatments across public and private ownerships is vital to effectively restore the sage-steppe ecosystem for nesting sage-grouse.

Control of pinon-juniper woodlands by mechanical treatments and prescribed fire are commonly applied to recover sagebrush steppe rangelands. Recently, the Sage Grouse Initiative has made conifer removal a major part of its program to reestablish sagebrush habitat for sage grouse (Centrocercus urophasianus) and other species. We analyzed data sets from previous and ongoing studies across the Great Basin characterizing cover response of perennial and annual forbs that are consumed by sage grouse to mechanical, prescribed fire, and low-disturbance fuel reduction treatments. There were 11 sites inwestern juniper (Juniperus occidentalis Hook.) woodlands, 3 sites in singleleaf pinon (Pinus monophylla Torr. & Frem.) and Utah juniper (Juniperus osteosperma [Torr.] Little), 2 sites in Utah juniper, and 2 sites in Utah juniper and Colorado pinon (Pinus edulis Engelm). Western juniper sites were located in mountain big sagebrush (A. tridentata ssp. vaseyana) steppe associations, and the other woodlands were located in Wyoming big sagebrush (A. tridentata ssp. wyomingensis) associations. Site potential appears to be a major determinant for increasing perennial forbs consumed by sage grouse following conifer control. The cover response of perennial forbs, whether increasing (1.5- to 6-fold) or exhibiting no change, was similar regardless of conifer treatment. Annual forbs favored by sage grouse benefitted most from prescribed fire treatments with smaller increases following mechanical and fuel reduction treatments. Though forb abundance may not consistently be enhanced, mechanical and fuel reduction conifer treatments remain good preventative measures, especially in phase 1 and 2 woodlands, which, at minimum, maintain forbs on the landscape. In addition, these two conifer control measures, in the short term, are superior to prescribed fire for maintaining the essential habitat characteristics of sagebrush steppe for sage grouse.

The impacts of juniper encroachment on critical ecohydrological relationships among snow distribution, water budgets, plant community transitions, and habitat requirements for wildlife, such as the greater sage grouse (Centrocercus urophasianus), remain poorly understood. The goal of this study is to better understand how juniper encroachment affects water availability for ecohydrologic processes and associated wildlife habitat in snow-dominated sagebrush (Artemisia spp.) steppe ecosystems. A 6-yr combined measurement and modeling study is conducted to explore differences in snow distribution, water availability, and annual water balances between juniper-dominated and sagebrush-dominated catchments. Although there is large interannual variability in both measured weather data and modeled hydrologic fluxes during the study, results indicate that juniper-dominated catchments have greater peak accumulations of snow water equivalent, earlier snow melt, and less streamflow relative to sagebrush-dominated catchments. Water delivery is delayed by an average of 9 days in the sagebrush-dominated scenario compared with the juniper-dominated scenario as a result of increased water storage in snow drifts. The delayed water input to sagebrush-dominated ecosystems in typical water years has wide-ranging implications for available surface water, soil water, and vegetation dynamics associated with wildlife habitat for sagebrush obligates such as sage grouse. Results from this study imply that the retention of high-elevation, sagebrush-dominated landscapes may become crucial for sage grouse habitat management if mid- and low-elevation precipitation continues to transition from snow to rain dominated.

TI The Sage-Grouse Habitat Mortgage: Effective Conifer Management in Space and Time SO RANGELAND ECOLOGY & MANAGEMENT LA English DT Article DE cutting; fire; juniper; pinyon; prescribed burning; sagebrush ID JUNIPER JUNIPERUS-OCCIDENTALIS; MOUNTAIN BIG SAGEBRUSH; WESTERN JUNIPER; GREAT-BASIN; POSTFIRE RECOVERY; FIRE; VEGETATION; WOODLANDS; PATTERNS; OREGON AB Management of conservation-reliant species can be complicated by the need to manage ecosystem processes that operate at extended temporal horizons. One such process is the role of fire in regulating abundance of expanding conifers that disrupt sage-grouse habitat in the northern Great Basin of the United States. Removing conifers by cutting has a beneficial effect on sage-grouse habitat. However, effects may last only a few decades because conifer seedlings are not controlled and the seed bank is fully stocked. Fire treatment may be preferred because conifer control lasts longer than for mechanical treatments. The amount of conservation needed to control conifers at large temporal and spatial scales can be quantified by multiplying land area by the time needed for conifer abundance to progress to critical thresholds (i.e., "conservation volume"). The contribution of different treatments in arresting conifer succession can be calculated by dividing conservation volume by the duration of treatment effect. We estimate that fire has approximately twice the treatment life of cutting at time horizons approaching 100 yr, but, has high up-front conservation costs due to temporary loss of sagebrush. Cutting has less up-front conservation costs because sagebrush is unaffected, but it is more expensive over longer management time horizons because of decreased durability. Managing conifers within sage-grouse habitat is difficult because of the necessity to maintain themajority of the landscape in sagebrush habitat and because the threshold for negative conifer effects occurs fairly early in the successional process. The time needed for recovery of sagebrush creates limits to fire use in managing sage-grouse habitat. Utilizing a combination of fire and cutting treatments is most financially and ecologically sustainable over long time horizons involved in managing conifer-prone sage-grouse habitat.

The need for such coupling between experimental data and stress functions is due to the fact that experimental techniques offer discrete information of stresses or displacements, e.g. isopachic stresses in the case of TSA, as well as unreliable data near edges. For TSA, additional information is needed to separate stresses, as it is often necessary for fatigue analysis and a general better understanding of structural integrity. This separation is often accomplished by using an Airy stress function, which stems from compatibility and equilibrium conditions, and is frequently represented in the form of an indefinite series of coefficients. To date, only ad hoc estimates for the number of coefficients necessary for accurate representation of a loaded structure are used, with the estimates being influenced by quality of experimental data, experimental noise, and complexity of loading and boundary conditions. Information presented here attempts to systematize the selection of the Airy stress function's indefinite series coefficients relative to experimental thermographic data. C1 [Samad, W.

The specimen was divided into three subregions based on axial strain magnitude. VFM analysis showed that the subregions had stiffnesses and Poisson's ratio's that varied in a monotonically decreasing fashion, but with the stiffness differences between subregions increasing with applied tensile stress. An Equilibrium Gap analysis showed improved local equilibrium when comparing a homogeneous analysis with the subregion analysis. Although only a single specimen was examined, results suggest that high stiffness regions provide only marginal improvement of mechanical behavior. The analysis also showed that even though the subregions themselves were non-contiguous, their mechanical behavior was similar. C1 [Hagman, Anton] KTH, Tekn Ringen 8, S-10044 Stockholm, Sweden.

SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID DISEASE-RESISTANCE; CULTIVATED SUNFLOWER; PLASMOPARA-HALSTEDII; CLADOSPORIUM-FULVUM; GERMPLASM LINES; LINKAGE MAP; EVOLUTION; LOCUS; REGISTRATION; MARKERS AB A new downy mildew resistance gene, Pl (19) , was identified from wild Helianthus annuus accession PI 435414, introduced to confection sunflower, and genetically mapped to linkage group 4 of the sunflower genome. Wild Helianthus annuus accession PI 435414 exhibited resistance to downy mildew, which is one of the most destructive diseases to sunflower production globally. Evaluation of the 140 BC1F2:3 families derived from the cross of CMS CONFSCLB1 and PI 435414 against Plasmopara halstedii race 734 revealed that a single dominant gene controls downy mildew resistance in the population. Bulked segregant analysis conducted in the BC1F2 population with 860 simple sequence repeat (SSR) markers indicated that the resistance derived from wild H. annuus was associated with SSR markers located on linkage group (LG) 4 of the sunflower genome. To map and tag this resistance locus, designated Pl (19) , 140 BC1F2 individuals were used to construct a linkage map of the gene region. Two SSR markers, ORS963 and HT298, were linked to Pl (19) within a distance of 4.7 cM. After screening 27 additional single nucleotide polymorphism (SNP) markers previously mapped to this region, two flanking SNP markers, NSA_003564 and NSA_006089, were identified as surrounding the Pl (19) gene at a distance of 0.6 cM from each side. Genetic analysis indicated that Pl (19) is different from Pl (17) , which had previously been mapped to LG4, but is closely linked to Pl (17) . This new gene is highly effective against the most predominant and virulent races of P. halstedii currently identified in North America and is the first downy mildew resistance gene that has been transferred to confection sunflower. The selected resistant germplasm derived from homozygous BC2F3 progeny provides a novel gene for use in confection sunflower breeding programs. C1 [Zhang, Z.

Intermediate wheatgrass (Thinopyrum intermedium) has been identified as a candidate for domestication and improvement as a perennial grain, forage, and biofuel crop and is actively being improved by several breeding programs. To accelerate this process using genomics-assisted breeding, efficient genotyping methods and genetic marker reference maps are needed. We present here the first consensus genetic map for intermediate wheatgrass (IWG), which confirms the species' allohexaploid nature (2n = 6x = 42) and homology to Triticeae genomes. Genotyping-by-sequencing was used to identify markers that fit expected segregation ratios and construct genetic maps for 13 heterogeneous parents of seven full-sib families. These maps were then integrated using a linear programming method to produce a consensus map with 21 linkage groups containing 10,029 markers, 3601 of which were present in at least two populations. Each of the 21 linkage groups contained between 237 and 683 markers, cumulatively covering 5061 cM (2891 cM--Kosambi) with an average distance of 0.5 cM between each pair of markers. Through mapping the sequence tags to the diploid (2n = 2x = 14) barley reference genome, we observed high colinearity and synteny between these genomes, with three homoeologous IWG chromosomes corresponding to each of the seven barley chromosomes, and mapped translocations that are known in the Triticeae. The consensus map is a valuable tool for wheat breeders to map important disease-resistance genes within intermediate wheatgrass. These genomic tools can help lead to rapid improvement of IWG and development of high-yielding cultivars of this perennial grain that would facilitate the sustainable intensification of agricultural systems.

Tifang barley also harbors resistance to P. teres f. teres which was previously shown to localize to barley chromosome 3H. A CIho 5791 x Tifang F-6 recombinant inbred line (RIL) population was developed using single seed descent. The Illumina iSelect SNP platform was used to identify 2562 single nucleotide polymorphism (SNP) markers across the barley genome, resulting in seven linkage maps, one for each barley chromosome. The CIho 5791 x Tifang RIL population was evaluated for NFNB resistance using nine P. teres f. teres isolates collected globally. Tifang was resistant to four of the isolates tested whereas CIho 5791 was highly resistant to all nine isolates. QTL analysis indicated that the CIho 5791 resistance mapped to chromosome 6H whereas the Tifang resistance mapped to chromosome 3H. Additionally, CIho 5791 also harbored resistance to two Japanese isolates that mapped to a 3H region similar to that of Tifang. SNP markers and RILs harboring both 3H and 6H resistance will be useful in resistance breeding against NFNB. C1 [Koladia, V. M.; Richards, J. K.; Brueggeman, R. S.; Friesen, T.

This article considers how promission and antiwar veterans' narrate their experiences of becoming political activists and the mechanisms that effect that transition. The research draws on narratives from 40 members of the antiwar organization Iraq Veterans against the War and 28 members of the promission organization Vets for Freedom. Using exemplars from opposing political groups, the article reveals the shared process of politicization for both groups of veterans, and how divergent promission and antiwar definitions of duty, service, patriotism, and narratives of experiences and interpretations of warfare activate meaning-making activities, mechanisms, and analytical frames that share more in common than surface political differences might suggest.

Results showed that three bleaching steps were required to remove most of the non-cellulosic constituents of the spines that yielded 77.4% cellulose. Nanowhiskers size decreased from about 400 to 260 nm when extraction time varied from 60 to 120 min, this was also evidenced by X-ray diffraction. Alkaline treated and bleached samples had lower thermal stability as compared to untreated spines due to removal of lignin and increased surface area. The amount of time samples were treated with sulfuric acid influenced the thermal stability and consequently the degree of crystallinity of the nanowhiskers. Cellulose nanowhiskers were obtained from Mandacaru spines providing a new renewable source of reinforcement with potential applications in nanocomposites.

Empirical statistical models and process-based simulations agree almost universally. The key relationship for this unanimity, observed at multiple spatial and temporal scales, is between drought and fire. Predictive models often focus on ecosystems in which this relationship appears to be particularly strong, such as mesic and arid forests and shrublands with substantial biomass such as chaparral. We examine the drought-fire relationship, specifically the correlations between water-balance deficit and annual area burned, across the full gradient of deficit in the western USA, from temperate rainforest to desert. In the middle of this gradient, conditional on vegetation (fuels), correlations are strong, but outside this range the equivalence hotter and drier equals more fire either breaks down or is contingent on other factors such as previous-year climate. This suggests that the regional drought-fire dynamic will not be stationary in future climate, nor will other more complex contingencies associated with the variation in fire extent. Predictions of future wildfire area therefore need to consider not only vegetation changes, as some dynamic vegetation models now do, but also potential changes in the drought-fire dynamic that will ensue in a warming climate.

Addressing this need, we studied current patterns of hydrologic alteration in the Marcellus Shale region and related the estimated flow alteration to fish community measures. We then used these empirical flow-ecology relationships to evaluate alternative surface water withdrawals and environmental flow rules. Reduced high-flow magnitude, dampened rates of change, and increased low-flow magnitudes were apparent regionally, but changes in many of the flow metrics likely to be sensitive to withdrawals also showed substantial regional variation. Fish community measures were significantly related to flow alteration, including declines in species richness with diminished annual runoff, winter low-flow, and summer median-flow. In addition, the relative abundance of intolerant taxa decreased with reduced winter high-flow and increased flow constancy, while fluvial specialist species decreased with reduced winter and annual flows. Stream size strongly mediated both the impact of withdrawal scenarios and the protection-afforded by environmental flow standards. Under the most intense withdrawal-scenario, 75% of reference headwaters and creeks (drainage areas < 99 km(2)) experienced at least 78% reduction in summer flow, whereas little change was predicted for larger rivers. Moreover, the least intense withdrawal scenario still-reduced summer flows by at least 21% for 50% of headwaters and creeks. The observed 90th quantile flow-ecology relationships indicate that such alteration could reduce species richness by 23% or more. Seasonally varying environmental flow standards and high fixed minimum flows protected the most streams from hydrologic alteration, but common minimum flow standards left numerous locations vulnerable to substantial flow alteration. This study clarifies how additional water demands in the region may adversely affect freshwater biological integrity. The-results make clear that policies to limit or prevent water withdrawals from smaller streams can reduce the risk of ecosystem impairment. C1 [Buchanan, Brian P.; Walter, M.

Nonnative trees planted in novel habitats often exhibit exceptional growth, in part because they escape herbivore (such as Scolytinae) pressure from their native range. Increasing accidental introductions of forest pest species as a consequence of international trade, however, is expected to diminish enemy release of nonnative forest trees. In this context, there is need to characterize patterns of forest herbivore species invasion risks at global scales. In this study, we analyze the establishment potential of 64 North American Scolytinae species in the Southern Hemisphere. We use climate-based ecological niche models (MaxEnt) to spatially define the potential distribution of these Scolytinae species in regions of the Southern Hemisphere were pines are planted. Our model predicts that all of the pine-growing regions of the Southern Hemisphere are capable of supporting some species of North American Scolytinae, but there are certain "hotspot" regions, southeastern Argentina, Bolivia, Chile, Peru and southwestern Australia, that appear to be suitable for a particularly large number of species. The species with the highest predicted risk of establishment were Dendroctonus valens, Xyleborus intrusus, Hylastes tenuis, Ips grandicollis, Gnathotrichus sulcatus, and Ips calligraphus. Given that global commerce is anticipated to continue to increase, we can expect that more Scolytinae species will continue to establish outside their range. Our results provide information useful for identifying a global list of potential invasive species in pine plantations, and may assist in the design of comprehensive strategies aimed at reducing pest establishment in Southern Hemisphere forest plantations.

TI Assessment of USDA-NRCS rangeland conservation programs: recommendation for an evidence-based conservation platform SO ECOLOGICAL APPLICATIONS LA English DT Article DE knowledge coproduction; policy-relevant science; rangeland stewardship; resilience-based management; science-policy gap ID RESOURCE MANAGEMENT; LAND MANAGEMENT; KNOWLEDGE; SCIENCE; PAYMENTS; INFORMATION; RESILIENCE; WORLD AB The Conservation Effects Assessment Project (CEAP) was created in response to a request from the Office of Management and Budget that the U.S. Department of Agriculture, Natural Resource Conservation Service (USDA-NRCS) document the societal benefits anticipated to accrue from a major increase in conservation funding authorized by the 2002 Farm Bill. A comprehensive evaluation of the efficacy of rangeland conservation practices cost-shared with private landowners was unable to evaluate conservation benefits because outcomes were seldom documented. Four interrelated suppositions are presented to examine the causes underlying minimal documentation of conservations outcomes. These suppositions are (1) the benefits of conservation practices are considered a certainty so that documentation in not required, (2) there is minimal knowledge exchange between the USDA-NRCS and research organizations, (3) and a paucity of conservation-relevant science, as well as (4) inadequate technical support for land owners following implementation of conservation practices. We then follow with recommendations to overcome potential barriers to documentation of conservation outcomes identified for each supposition. Collectively, this assessment indicates that the existing conservation practice standards are insufficient to effectively administer large conservation investments on rangelands and that modification of these standards alone will not achieve the goals explicitly stated by CEAP. We recommend that USDA-NRCS modify its conservation programs around a more comprehensive and integrative platform that is capable of implementing evidence-based conservation. Collaborative monitoring organized around landowner-agency-scientist partnerships would represent the focal point of a Conservation Program Assessment Network (CPAN). The primary network objective would be to establish missing information feedback loops between conservation practices and their agricultural and environmental outcomes to promote learning, adaptive management, and innovation. Network information would be archived and made available to guide other, related conservation programs in relevant ecoregions. Restructuring conservation programs as we recommend would (1) provide site specific information, learning, and accountability that has been requested by CEAP and (2) further advance balanced delivery of agricultural production and environmental quality goals.

Quantifying E-C is of both scientific and practical importance, providing information relevant to questions ranging from energy partitioning to ecosystem services, such as primary productivity and water yield. We estimated E-C of four pine stands differing in age and growing on sandy soils. The stands consisted of two wide-ranging conifer species: Pinus taeda and Pinus sylvestris, in temperate and boreal zones, respectively. Combining results from these and published studies on all soil types, we derived an approach to estimate daily E-C of pine forests, representing a wide range of conditions from 35 degrees S to 64 degrees N latitude. During the growing season and under moist soils, maximum daily E-C (E-Cm) at day-length normalized vapor pressure deficit of 1 kPa (ECm-ref) increased by 0.55 +/- 0.02 (mean +/- SE) mm/d for each unit increase of leaf area index (L) up to L = similar to 5, showing no sign of saturation within this range of quickly rising mutual shading. The initial rise of E-Cm with atmospheric demand was linearly related to ECm-ref. Both relations were unaffected by soil type. Consistent with theoretical prediction, daily E-C was sensitive to decreasing soil moisture at an earlier point of relative extractable water in loamy than sandy soils. Our finding facilitates the estimation of daily E-C of wide-ranging pine forests using remotely sensed L and meteorological data. We advocate an assembly of worldwide sap flux database for further evaluation of this approach.

While ungulate herbivores generally reduce standing biomass, their effects on aboveground net primary production (ANPP) can vary by spatial and temporal context, intensity of herbivory, and herbivore identity and species richness. Some evidence indicates that moderate levels of herbivory can stimulate aboveground productivity, but few studies have explicitly tested the relationships among herbivore identity, grazing intensity, and ANPP. We used a long-term exclosure experiment to examine the effects of three groups of wild and domestic ungulate herbivores (megaherbivores, mesoherbivore wildlife, and cattle) on herbaceous productivity in an African savanna. Using both field measurements (productivity cages) and satellite imagery, we measured the effects of different herbivore guilds, separately and in different combinations, on herbaceous productivity across both space and time. Results from both productivity cage measurements and satellite normalized difference vegetation index (NDVI) demonstrated a positive relationship between mean productivity and total ungulate herbivore pressure, driven in particular by the presence of cattle. In contrast, we found that variation in herbaceous productivity across space and time was driven by the presence of wild herbivores (primarily mesoherbivore wildlife), which significantly reduced heterogeneity in ANPP and NDVI across both space and time. Our results indicate that replacing wildlife with cattle (at moderate densities) could lead to similarly productive but more heterogeneous herbaceous plant communities in rangelands.

TI Ecosystem carbon density and allocation across a chronosequence of longleaf pine forests SO ECOLOGICAL APPLICATIONS LA English DT Article DE carbon dynamics; carbon storage; chronosequence; forest structure; longleaf pine; Pinus palustris; root-to-shoot ratio; stand age ID SOUTHEASTERN UNITED-STATES; LOBLOLLY-PINE; ROOT BIOMASS; SOIL CARBON; OLD-GROWTH; TERRESTRIAL BIOMES; PRESCRIBED FIRE; WORLDS FORESTS; COASTAL-PLAIN; STORAGE AB Forests can partially offset greenhouse gas emissions and contribute to climate change mitigation, mainly through increases in live biomass. We quantified carbon (C) density in 20 managed longleaf pine (Pinus palustris Mill.) forests ranging in age from 5 to 118 years located across the southeastern United States and estimated above-and belowground C trajectories. Ecosystem C stock (all pools including soil C) and aboveground live tree C increased nonlinearly with stand age and the modeled asymptotic maxima were 168 Mg C/ha and 80 Mg C/ha, respectively. Accumulation of ecosystem C with stand age was driven mainly by increases in aboveground live tree C, which ranged from < 1 Mg C/ha to 74 Mg C/ha and comprised < 1% to 39% of ecosystem C. Live root C (sum of below-stump C, ground penetrating radar measurement of lateral root C, and live fine root C) increased with stand age and represented 4-22% of ecosystem C. Soil C was related to site index, but not to stand age, and made up 39-92% of ecosystem C. Live understory C, forest floor C, downed dead wood C, and standing dead wood C were small fractions of ecosystem C in these frequently burned stands. Stand age and site index accounted for 76% of the variation in ecosystem C among stands. The mean root-to-shoot ratio calculated as the average across all stands (excluding the grass-stage stand) was 0.54 (standard deviation of 0.19) and higher than reports for other conifers. Long-term accumulation of live tree C, combined with the larger role of belowground accumulation of lateral root C than in other forest types, indicates a role of longleaf pine forests in providing disturbance-resistant C storage that can balance the more rapid C accumulation and C removal associated with more intensively managed forests. Although other managed southern pine systems sequester more C over the short-term, we suggest that longleaf pine forests can play a meaningful role in regional forest C management.

However, these frameworks, as well as the experiments designed to test them, rarely include belowground herbivores. We experimentally challenged seedlings of the tropical shrub Solanum lycocarpum (Solanaceae) with either aboveground foliar herbivores (Spodoptera caterpillars) or belowground root herbivores (the nematode Meloidogyne incognita) and measured the resulting changes in plant growth rates, biomass allocation, and the concentration of defensive terpenoids in roots and leaves. We found that plants that suffered aboveground herbivory responded with aboveground growth but belowground defense. Similarly, belowground herbivory resulted in root growth but elevated defenses of leaves. These results underscore the importance of belowground plant-herbivore interactions, and suggest that, in contrast to theoretical predictions, plants can simultaneously invest in both growth and defense. Finally, they emphasize the need for a "whole-plant" perspective in theoretical and empirical evaluations of plant-herbivore interactions. C1 [Mundim, Fabiane M.; Vieira-Neto, Ernane H.

Although common genecological patterns have emerged, species-specific details are also important. Which species are most vulnerable to climate change? Which are the most important adaptive traits and environmental drivers of natural selection? Even though species have been classified as adaptive specialists vs. adaptive generalists, large-scale studies comparing different species in the same experiment are rare. We studied the genecology of Norway spruce (Picea abies) and silver fir (Abies alba), two co-occurring but ecologically distinct European conifers in Central Europe. For each species, we collected seed from more than 90 populations across Switzerland, established a seedling common-garden test, and developed genecological models that associate population variation in seedling growth and phenology to climate, soil properties, and site water balance. Population differentiation and associations between seedling traits and environmental variables were much stronger for Norway spruce than for silver fir, and stronger for seedling height growth than for bud phenology. In Norway spruce, height growth and second flushing were strongly associated with temperature and elevation, with seedlings from the lowlands being taller and more prone to second flush than seedlings from the Alps. In silver fir, height growth was more weakly associated with temperature and elevation, but also associated with water availability. Soil characteristics explained little population variation in both species. We conclude that Norway spruce has become an adaptive specialist because trade-offs between rapid juvenile growth and frost avoidance have subjected it to strong diversifying natural selection based on temperature. In contrast, because silver fir has a more conservative growth habit, it has evolved to become an adaptive generalist. This study demonstrates that co-occurring tree species can develop very different adaptive strategies under identical environmental conditions, and suggests that Norway spruce might be more vulnerable to future maladaptation due to rapid climate change than silver fir.

Fungal presence is generally confirmed by microscopy, disappearance of symptoms in livestock after removal of suspect forage, and chromatography of the alkaloid slaframine, in legume tissue. Use of the polymerase chain reaction (PCR) to amplify a pathogen-specific DNA fragment would complement the other methods of pathogen identification. Primers were designed to the R. leguminicola ITS region, sequence provided by another laboratory. Two separate primer pairs each amplified a different fragment-one similar to 250 bp long (expected length 249 bp), and the other 300 to 400 bp long (expected length 368 bp)-in DNA extracted from cultures of R. leguminicola. Under the experimental conditions, the primers to the larger fragment amplified a stronger band, and a minimum of 0.1 ng DNA per reaction was needed to produce a detectable band. With the primers to the 368-bp fragment, a band 300 to 400 bp long was also amplified in DNA extracted from red clover (cultivar Kenland) inoculated with R. leguminicola and harvested 70 h post inoculation. No amplification with this primer set occurred in DNA extracted from mock-inoculated red clover plants, supporting the likelihood that the primers amplified R. leguminicola DNA extracted from inoculated red clover. This primer set did not amplify DNA extracted from a red clover isolate of the legume pathogen Stemphylium sarcinaeforme, or DNA extracted from two isolates of the legume pathogen Colletotrichum trifolii, indicating specificity for R. leguminicola DNA. Lack of amplification of alfalfa DNA indicated that the R. leguminicola primers will be useful for testing for the presence of blackpatch in alfalfa.

Several studies have provided evidence that cattle hides are the main source of beef carcass contamination during processing and that reductions in the E. coli O157:H7 load on the hides of cattle entering processing facilities will lead to reductions in carcass contamination. Bacteriophages have been proposed as a novel preharvest antimicrobial intervention to reduce the levels of E. coli O157:H7 on cattle hides. The objective of this study was to evaluate a commercialized phage application administered in the lairage area of commercial beef processing plants for the ability to reduce E. coli O157:H7 contamination of cattle hides and carcasses. Cattle lots either received phage spray treatment (n = 289) or did not (n = 301), as they entered the lairage environments in two separate experiments at two different commercial beef processing plants. Hide and carcass samples were collected and analyzed for E. coli O157:H7 prevalence and concentration. Cattle hides receiving phage treatment had an E. coli O157:H7 prevalence of 51.8%, whereas untreated hides had a prevalence of 57.6%. For carcass samples, the E. coli O157 prevalence in treated and untreated samples was 17.1% and 17.6%, respectively. The results obtained from these experiments demonstrated that the treatment of cattle hides with bacteriophages before processing did not produce a significant reduction of E. coli O157:H7 on cattle hides or beef carcasses during processing.

TI The inter-annual variability of southerly low-level jets in North America SO INTERNATIONAL JOURNAL OF CLIMATOLOGY LA English DT Article DE southerly low-level jet; empirical orthogonal functions (EOFs); Pacific Decadal Oscillation (PDO); El Nino Southern Oscillation (ENSO); El Nino Modoki ID CENTRAL UNITED-STATES; GREAT-PLAINS; WARM-SEASON; CLIMATOLOGY; MODEL; PRECIPITATION; CYCLOGENESIS; OSCILLATION; CIRCULATION; GULF AB The inter-annual variability of southerly low-level jets (SLLJs) over North America during the warm (April-September) and cool (October-March) seasons is investigated. SLLJ occurrences over a 31-year period (1979-2009) were identified from the North American Regional Reanalysis (NARR) vertical wind profiles. The first empirical orthogonal function (EOF) modes of the SLLJ frequency during the warm and cool seasons account for about 30 and 20% of the total variance, respectively. Both modes can be interpreted as a strengthening or weakening of the core area of SLLJ anomalies. The principal component (PC) time series display significant positive trends, suggesting an increase in SLLJ activity during both seasons on inter-decadal time scales and are significantly correlated to the summertime Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) for the warm season and the wintertime PDO, AMO and El Nino Modoki for the cool season. The second modes account for about 20 and 15% of the total variance for the warm and cool seasons, respectively, and are interpreted as primarily a subseasonal latitudinal shift in SLLJ activity between the central Great Plains and the western Gulf of Mexico and southern Texas during the warm season and a longitudinal shift between the western Gulf of Mexico and the Caribbean during the cool season. The second mode appears to be significantly correlated to El Nino Modoki for the warm season and to Nino 3.4 for the cool season. C1 [Yu, Lejiang] Polar Res Inst China, Shanghai, Peoples R China.

However, it is essential to evaluate long-term performance of the phase change materials and cost-effectiveness prior to full-scale implementation. For this reason, we have used the accelerated long-term approach for studying the thermal performance and chemical stability of a commercially available bio-based phase change material during thermal cycling over a simulated period of 20years. The phase change material was subjected to accelerate thermal aging under controlled environmental conditions. Small samples of the phase change material were periodically removed to measure its latent heat, thermal decomposition, and chemical stability using various analytical methods such as differential scanning calorimetry, thermogravimetry analysis, and infrared spectroscopy. The topographic changes in the phase change material due to the aging process were observed using scanning electron microscopy. The differential scanning calorimetry data indicate a significant reduction of 12% in the latent heat during heating and cooling cycles during the initial 6.2years remain nearly constant thereafter. The thermogravimetry analysis results showed that the phase change material has excellent thermal stability within the working temperature range and also shows long-term decomposition temperature stability. The Fourier transform infrared spectra of the phase change material indicate absorption of moisture but the phase change material was chemically stable over the duration of accelerated aging cycles. After several aging cycles, the baseline surface morphology appeared to be changed from uniform mix of phase change material with microstructures to segregated microstructures as evidenced by the observation of the scanning electron micrographs.

To characterize its implementation, we undertook an inventory of what we refer to as fire-focused all lands management (ALM) projects, defined as projects in which fuels reduction treatments are planned or implemented across more than one landownership to reduce wildfire risk or increase forest resilience to wildfire. We focused on regions of Washington, Oregon, and California dominated by dry, fire-prone forests and documented 41 projects. From this sample we developed a typology with five project categories. We found that ALM takes many forms and occurs in diverse contexts, federal lands and land managers are frequently involved in them, and all projects foster relationship and capacity building for future ALM. Our typology provides a framework for better understanding of all lands approaches and suggests areas for further investigation.

We conducted rapid appraisal baseline research for pilot projects in this program in three Southern states using a carefully selected purposive sample to enhance our understanding of minority landownership and forest management. We found that whereas land represents an important family resource across generations, heirs' property status often results in insecure property ownership, and most families receive little or no economic return from their land. Forest stands tended to be naturally regenerated pine forests that require thinning, burning, or even complete harvest and replanting if owners are to benefit economically from forestry. Forestry can help families retain land and build assets, although most of the African American landowners included in our study noted that their previous engagement with forestry has been limited to opportunistic timber sales. Landowners expressed broad interest in future engagement in forestry activities and managing for wildlife. Our interview with landowners revealed that the community-based pilot projects were building links among landowners and foresters to encourage sustainable forest management and retention of African American family land.

TI Participatory Geographic Information Systems as an Organizational Platform for the Integration of Traditional and Scientific Knowledge in Contemporary Fire and Fuels Management SO JOURNAL OF FORESTRY LA English DT Article DE fire and fuels management; traditional knowledge; indigenous knowledge; Participatory Geographic Information Systems ID ECOLOGICAL KNOWLEDGE; SCIENCE; CLASSIFICATION; CHALLENGES; WILDFIRE; HISTORY AB Traditional knowledge about fire and its effects held by indigenous people, who are connected to specific landscapes, holds promise for informing contemporary fire and fuels management strategies and augmenting knowledge and information derived from western science. In practice, however, inadequate means to organize and communicate this traditional knowledge with scientists and managers can limit its consideration in decisions, requiring novel approaches to interdisciplinary and cross-cultural communication and collaboration. We propose that Participatory Geographic Information Systems (PGIS) is one platform for the assemblage and communication of traditional knowledge vital to fire and fuels management, while preserving linkages to broader cultural contexts. We provide summaries of four preliminary case studies in the Intermountain West of North America to illustrate different potential applications of a PGIS tool in this context and describe some remaining challenges.

Objective To describe major food sources, places obtained, and eating occasions contributing to sodium intake among US school-aged children. Design Cross-sectional analysis of data from the 2011-2012 National Health and Nutrition Examination Survey. Participants/setting A nationally representative sample of 2,142 US children aged 6 to 18 years who completed a 24-hour dietary recall. Main outcome measures Population proportions of sodium intake from major food categories, places, and eating occasions. Statistical analyses performed Statistical analyses accounted for the complex survey design and sampling. Wald F tests and t tests were used to examine differences between subgroups. Results Average daily sodium intake was highest among adolescents aged. 14 to 18 years (3,565 120 mg), lowest among girls (2,919 74 mg). Little variation was seen in average intakes or the top five sodium contributors by sociodemographic characteristics or weight status. Ten food categories contributed to almost half (48%) of US school-aged children's sodium intake, and included pizza, Mexican-mixed dishes, sandwiches, breads, cold cuts, soups, savory snacks, cheese, plain milk, and poultry. More than 80 food categories contributed to the other half of children's sodium intake. Foods obtained from stores contributed 58% of sodium intake, fast-food/pizza restaurants contributed 16%, and school cafeterias contributed 10%. Thirty-nine percent of sodium intake was consumed at dinner, 31% at lunch, 16% from snacks, and 14% at breakfast. Conclusions With the exception of plain milk, which naturally contains sodium, the top 10 food categories contributing to US schoolchildren's sodium intake during 2011-2012 comprised foods in which sodium is added during processing or preparation. Sodium is consumed throughout the day from multiple foods and locations, highlighting the importance of sodium reduction across the US food supply. C1 [Quader, Zerleen S.] IHRC Inc, Atlanta, GA USA.

Objective This study investigated whether there were differences in school lunch foods consumed and wasted by grade level of elementary school students. Design In this cross-sectional study, anonymous meal observations were conducted after students selected their reimbursable school lunch meals in the cafeteria lunch line. The amounts of foods selected and consumed were recorded using the quarter waste method and food waste was calculated using the information recorded. Participants/setting During the spring of 2013, eight elementary schools (50% low income) enrolling children in kindergarten through grade 5 in one school district in the Houston, TX, area were selected by the Child Nutrition Director. Main outcome measures The amount of calories and foods consumed and the percentage wasted were assessed. Statistical analyses performed Analysis of covariance and post hoc analysis were used to examine food consumption and plate waste by grade level (kindergarten and grade 1 [K-Gr1], grades 2 and 3 [Gr2-3], and grades 4 and 5 [Gr4-5]), controlling for student sex and school-level free reduced priced meal eligibility. Results There were 568 nonrandom lunch meal observations of students included in the analyses. Approximately 48% of the observations were from boys; 50% were from low-income schools, and were evenly divided by grade. In general, students in K-Gr1 consumed fewer calories than both Gr2-3 and Gr4-5, and Gr2-3 students consumed significantly fewer calories than Gr4-5. K-Gr1 students also consumed less and wasted more total and red-orange vegetables, total/whole/refined grains, and total protein foods than the older students. Gr2-3 students wasted more calories and total grains than Gr4-5 students. K-Gr1 students wasted more fruit than Gr2-3 students. Conclusions Overall, younger students in elementary schools (K-Gr-1) consumed less of the foods they selected for their lunch meals, and wasted more than older elementary school students. Future studieS should investigate why younger children wasted more food and potential strategies to reduce food waste by younger students.

TI Effects of conifer expansion on greater sage-grouse nesting habitat selection SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE Centrocercus urophasianus; conifer expansion; Great Basin; Juniperus occidentalis; sagebrush; sage-grouse; western juniper ID ENERGY DEVELOPMENT; VEGETATIVE COMMUNITIES; BLUE MOUNTAINS; RANDOM FORESTS; CANOPY COVER; TREE HEIGHT; LIDAR DATA; SAGEBRUSH; LANDSCAPE; OREGON AB Expansion of conifer woodlands into sagebrush (Artemisia spp.) ecosystems is a primary threat to the greater sage-grouse (Centrocercus urophasianus) in the Great Basin, southeast Oregon, USA. Conifer removal to restore sage-grouse habitats has been widely implemented, yet limited information exists on the effects of conifer expansion on sage-grouse habitat selection. Our objective was to evaluate the landscape-scale effects of conifer expansion on selection of sites for nesting and to estimate direction, magnitude, and scale of effects. We classified 160 nests and 167 available sites with random forests during 2010-2011 to assess effects of conifer cover and tree clustering at multiple scales along with other vegetation and topographic covariates on selection of nesting habitat. Relative probability of nesting was negatively associated with >3% conifer cover within 800m of nests. When trees were present within 800m of nests, sage-grouse nested where trees were clustered rather than dispersed, suggesting selection for more open habitat. Results further indicated that sage-grouse are nesting in landscapes susceptible to conifer expansion that have yet to be invaded. Sage-grouse are expected to lose nesting habitat as conifer expansion continues, but management intervention may be a possible solution to increase habitat availability where open space for nesting is a limiting factor.

Understanding what influences variation in postfledging movements may provide insight into the differential value of habitat across life-history stages. We conducted a radio-telemetry study of postfledging ovenbirds (Seiurus aurocapilla; n=45) and Acadian flycatchers (Empidonax virescens; n=62) in mature-forest fragments from 2012 to 2015 in Missouri, USA. We documented variability in behavior and space use and used generalized linear mixed models to evaluate the relationship of postfledging movement rates to individuals' condition, temporal variables, and local habitat variables. We found effects of age and season on movement distances for both study species. Additionally, daily movements of fledgling ovenbirds were negatively related to understory foliage density, a characteristic previously linked to increased survival. Habitat features are useful in predicting the postfledging movements of ovenbirds. By including behavioral development (age) and season in movement models, we were able to isolate and detect habitat effects on movement of ovenbirds and Acadian flycatchers. We suggest researchers use models of daily movement to further strengthen resource quality hypotheses generated by habitat selection and survival studies. (c) 2016 The Wildlife Society.

In a grapevine (genus Vitis) breeding program, although experimental families are typically unreplicated, the genetic backgrounds may contain similar progenitors previously selected due to their contribution of favorable alleles. In this study, we investigated the utility of joint QTL identification provided by analyzing half-sib families. The genetic control of powdery mildew was studied using two half-sib F-1 families, namely GE0711/1009 (MN1264 x MN1214; N = 147) and GE1025 (MN1264 x MN1246; N = 125) with multiple species in their ancestry. Maternal genetic maps consisting of 1077 and 1641 single nucleotide polymorphism (SNP) markers, respectively, were constructed using a pseudotestcross strategy. Ratings of field resistance to powdery mildew were obtained based on whole-plant evaluation of disease severity. This 2-year analysis uncovered two QTLs that were validated on a consensus map in these half-sib families with improved precision relative to the parental maps. Examination of haplotype combinations based on the two QTL regions identified strong association of haplotypes inherited from 'Seyval blanc', through MN1264, with powdery mildew resistance. This investigation also encompassed the use of microsatellite markers to establish a correlation between 206bp (UDV-015b) and 357-bp (VViv67) fragment sizes with resistance-carrying haplotypes. Our work is one of the first reports in grapevine demonstrating the use of SNP-based maps and haplotypes for QTL identification and tagging of powdery mildew resistance in half-sib families.

To understand molecular and genetic basis underlying the large variation in their maturity and flowering times, we integrated pedigree and maturity data of 166 cultivars representing North American soybean breeding. Network analysis and visualization of their pedigree relationships revealed a clear separation of southern and northern soybean breeding programs, suggesting that little genetic exchange occurred between northern (MG 0-IV) and southern cultivars (MG V-VIII). We also analyzed the transcript sequence and expression levels of four major maturity genes (E1 to E4) and revealed their allelic variants in 75 major ancestral landraces and milestone cultivars. We observed that e1-as was the predominant e mutant allele in northern genotypes, followed by e2 and e3. There was no allelic variation at E4. Transcript accumulation of the e2 mutant allele was significantly reduced, which might be caused by its premature stop codon triggering the nonsense-mediated mRNA decay pathway. The large DNA deletion generating the e3 mutant allele also created a gene fusion transcript. The e alleles found in milestone cultivars were traced through pedigrees to their ancestral landraces and geographic origins. Our analysis revealed an approximate correlation between dysfunctional alleles and maturity groups for most of the 75 cultivars. However, single e mutant alleles and their combinations were not sufficient to fully explain their maturity diversity, suggesting that additional genes/alleles are likely involved in regulating maturity time.

PVC sections (internal surface area of 15.16 cm(2)) were utilized in the study to grow biofilm. After a 7-d test period, test coupons with 7-day-old biofilm were transferred into autoclaved municipal water and then treated with either chlorine-based or hydrogen peroxide-based sanitizer at bird drinking water rate, to see the impact on removal of biofilm formed on test coupons. Two trials (T1 and T2) were conducted. Test coupons used in T1 and T2 had the bacterial growth of 3.67 (SEM 0.04) and 3.97 (SEM 0.11) log10 cfu/cm(2) on d 7. After sanitizer application, chlorine-based sanitizer removed bacteria in biofilm completely (0 cfu/cm(2)) within 24 h post treatment whereas hydrogen peroxide-based sanitizer reduced the counts to 1.68 log10 cfu/cm(2) (P < 0.05) by 48 h post sanitizer application. Control remained the same (P > 0.05). Results indicated that biofilm formation can occur quickly under suboptimal water condition on PVC surface, and sanitizer application helped mitigate already formed biofilm, yet chlorine proved to be more effective than hydrogen peroxide.

TI Carcass orientation and drip time affect potential surface water carryover for broiler carcasses subjected to a post- chill water dip or spray SO POULTRY SCIENCE LA English DT Article DE broiler carcass; carcass orientation; spray; dip; water accumulation ID CAMPYLOBACTER; ANTIMICROBIALS; SALMONELLA; REDUCTION; TANK AB To estimate the potential for residual antimicrobial solution carryover, surface water accumulation and loss was measured on post-chill carcasses that were either dipped or sprayed with water. For all experiments, broilers were slaughtered, soft or hard scalded, defeathered, and eviscerated. Carcasses were immersion chilled, allowed to drip, and post-chill carcass weight (CW) recorded. For water dip treatment, carcasses were dipped for 0.5 min in water and hung by a wing (n = 33) or a leg (n = 30) and CW recorded at 0, 0.5, 1, 2, and 5 min post-dip. For water spray treatment, individual carcasses were hung by either the wings (n = 35) or legs (n = 34) from a shackle suspended from a scale. Water was sprayed at 80 psi and post-spray CW recorded. Initial water accumulation (0 min) for dipped carcasses was not significantly different (P > 0.05) for carcasses hung by the leg (101.0 g) or wing (108.8 g). Following the 5 min drip time, 31 g of water remained on the carcasses hung by the leg and only 10 g on carcasses hung by the wing (P < 0.05). When carcasses were sprayed with water, initial water accumulation (0 min) was 62 g for carcasses hung by the legs and 60 g for carcasses hung by the wings (P > 0.05). Following the 5 min drip time, 1 g or no water remained on the sprayed carcasses (P > 0.05). Carcasses that were dipped and hung by a leg for 5 min retained significantly more water (31 g) than carcasses that were dipped and hung by a wing (10 g) or sprayed carcasses hung either way (0.3 g) (P < 0.05). Post-chill water dip resulted in significantly higher initial carcass water accumulation than spraying (105 g vs. 61 g, P < 0.05). Carcass orientation during dripping only affected the amount of retained water for dipped carcasses. Dipped carcasses hung by a leg have the highest potential for residual carcass antimicrobial solution carryover and sprayed carcasses hung by either orientation have the lowest potential for residual antimicrobial solution carryover.

In the southeastern United States, piscivorous birds present a continuous challenge for producers of farm-raised catfish. Ciconiiform birds are common hosts of Clinostomum spp. in North America and are endemic on most commercial catfish operations. The great egret Ardea alba L. is an avian predator often found foraging on commercial catfish operations, but to date the trematode fauna of great egrets preying on catfish ponds remains mostly understudied. Thirteen great egrets were captured from commercial catfish ponds in northeast Mississippi, and examined for trematode infections. Two morphologically distinct Clinostomum spp. were observed in the great egrets sampled, one morphologically consistent with Clinostomum marginatum (Rudolphi, 1819) and one morphologically unique species. These morphological descriptions were supplemented with molecular sequence data (c.4,800 bp of ribosomal DNA and c.600 bp of mitochondrial DNA). Gene sequences confirmed the identification of C. marginatum. However, the second species differed significantly from its congeners in both morphology and DNA sequence. Given these distinct morphological and molecular characters we propose this second species as Clinostomum album n. sp.

Approximately 200 000 kidney transplant recipients are living in the United States; they are at increased risk for cardiovascular and other adverse outcomes. Biomarkers predicting these outcomes are needed. Using specimens collected during the Folic Acid for Vascular Outcome Reduction in Transplantation trial, we determined whether plasma levels of B-type natriuretic peptide (BNP) and cardiac troponin I are associated with adverse outcomes in stable kidney transplant recipients. Methods. Five hundred ten subjects were selected randomly from the 4110 Folic Acid for Vascular Outcome Reduction in Transplantation participants. This cohort was then enriched for all additional subjects with adverse outcomes (death, dialysis-dependent kidney failure (DDKF), and cardiovascular outcomes) for a total of 1131 participants studied. Quartiles of BNP and high-sensitivity cardiac troponin I (hs-cTnI) were included in adjusted models. Combinations of normal and elevated hs-cTnI (>26.2 ng/L) and BNP (>100 pg/mL) were also studied. Results. Median concentrations (interquartile ranges) were 5.6 (3.3-10.5) ng/L for hs-cTnI and 39 (15, 94) pg/mL for BNP. Hazard ratios for each adverse outcome were higher with higher quartiles of BNP after adjustment and remained statistically significant after adding hs-cTnI to the model. The highest quartile hazard ratio for DDKF was 2.47 (95% confidence interval [95% CI], 1.21-5.05). Simultaneous elevations of BNP and hs-cTnI over clinical cutoffs were strongly associated with adverse outcomes with hazard ratios 8.8 (95% CI, 3.4-23.1) for DDKF and 6.3 (95% CI, 2.7-15.0) for cardiovascular outcomes. Conclusions. Higher BNP is associated with mortality and cardiovascular and kidney outcomes in stable kidney transplant recipients. Elevated BNP and hs-cTnI identify candidates for targeted risk reduction. C1 [Jarolim, Petr; Conrad, Michael J.] Harvard Med Sch, Brigham & Womens Hosp, Dept Pathol, Boston, MA USA.

The lack of effective biochemical lignin depolymerization processes has led many to focus on thermochemical conversion methods. Bench scale microwave pyrolysis of lignin has been performed at 1200 W over the course of 15 min in the presence of a microwave absorber (activated charcoal). The liquid products obtained are composed of smaller polymeric components and moderate yields of monomeric phenols. However, upon the addition of 1,4-butanediol, repolymerization reactions that limit the yield of monomeric and other reduced molecular weight products are inhibited. A great reduction in the average molecular weight (similar to 85-90% decrease) of the liquid products was observed as well as an overall increase in liquid yield. At the optimized ratio of 2:1 lignin to 1,4-butanediol (w/w), the yield of selected monomeric phenols increased 3-fold to similar to 3.4 wt % (based on feedstock), while the yield of monoaromatic hydrocarbons decreased by approximately 90%. The addition of the diol coreactant also led to a significant shift in selectivity toward the production of methoxy-phenols (guaiacols, syringols) over nonmethoxylated alkyl-phenols (phenol, cresols, etc.). The results obtained may lead to the development of novel lignin coprocessing methods.

The efficiency of microwave heating depends largely on the dielectric properties of the materials being heated. The objective of this study was to investigate the dynamic interactions between microwave energy and the reaction system during the liquefaction of a woody biomass sample. The dielectric properties of poplar wood particles, model compounds representing the three main chemical components of wood, and individual liquefaction solvent components, along with their mixtures, were measured to evaluate their abilities to convert microwave energy to heat at different frequencies. Dry samples of wood particles, cellulose, xylan, and lignin were all poor microwave energy absorbers as indicated by their low dielectric values relative to the liquefaction solvent components and their mixtures; among the two solvents, polyethylene glycol had lower dielectric values than glycerol, likely due to its larger molecular size. Ionic conduction significantly affected the dielectric loss factor of the liquefaction solvent mixture upon the addition of the sulfuric acid catalyst. During the wood liquefaction reactions, temperature was the main factor that governed the dielectric properties through the preheating stage, and then when the system reached 130 degrees C, the dielectric properties were governed by changes in chemical composition.

The major form of vitamin K found in the liver is phylloquinone (K1). Menaquinone-4 (MK-4) is the form of vitamin K that is preferentially found in extra-hepatic tissues. Methods: In the present study, we assessed tissue concentrations of K1 and MK-4 and the expression of vitamin K-related genes in a rat model of adenine-induced CKD. Results: It was found that rats with both mild and severe CKD had significantly lower amounts of K1 measured in liver, spleen and heart and higher levels of MK-4 measured in kidney cortex and medulla. All animals treated with high dietary K1 had an increase in tissue levels of both K1 and MK-4; however, the relative increase in K1 differed suggesting that the conversion of K1 to MK-4 may be a regulated/limiting process in some tissues. There was a decrease in the thoracic aorta expression of vitamin K recycling (Vkor) and utilization (Ggcx) enzymes, and a decrease in the kidney level of vitamin K1 to MK-4 bioconversion enzyme Ubiad1 in CKD. Conclusion: Taken together, these findings suggest that CKD impacts vitamin K metabolism, and this occurs early in the disease course. Our findings that vitamin K metabolism is altered in the presence of CKD provides further support that sub-clinical vitamin K deficiency may represent a modifiable risk factor for vascular and bone health in this population.

TI Modeling genetic and nongenetic variation of feed efficiency and its partial relationships between component traits as a function of management and environmental factors SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE dry matter intake; genetic correlation; heritability; hierarchical Bayesian modeling ID BODY CONDITION SCORE; DAIRY-CATTLE; MILK-YIELD; VARIANCE; COWS; HETEROGENEITY; PREDICTION; PARAMETERS; SELECTION AB Feed efficiency (FE), characterized as the fraction of feed nutrients converted into salable milk or meat, is of increasing economic importance in the dairy industry. We conjecture that FE is a complex trait whose variation and relationships or partial efficiencies (PE) involving the conversion of dry matter intake to milk energy and metabolic body weight may be highly heterogeneous across environments or management scenarios. In this study, a hierarchical Bayesian multivariate mixed model was proposed to jointly infer upon such heterogeneity at both genetic and nongenetic levels on PE and variance components (VC). The heterogeneity was modeled by embedding mixed effects specifications on PE and VC in addition to those directly specified on the component traits. We validated the model by simulation and applied it to a joint analysis of a dairy FE consortium data set with 5,088 Holstein cows from 13 research stations in Canada, the Netherlands, the United Kingdom, and the United States. Although no differences were detected among research stations for PE at the genetic level, some evidence was found of heterogeneity in residual PE. Furthermore, substantial heterogeneity in VC across stations, parities, and ration was observed with heritability estimates of FE ranging from 0.16 to 0.46 across stations. C1 [Lu, Y.; Vandehaar, M.

TI Cow genotyping strategies for genomic selection in a small dairy cattle population SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE genomic selection; genotyping cows; cow genotyping strategies; Guernsey ID BREEDING VALUES; INFORMATION; PREDICTION; ACCURACY; ASSOCIATION; IMPUTATION; RELATIVES; PEDIGREE; SCHEMES; IMPACT AB This study compares how different cow genotyping strategies increase the accuracy of genomic estimated breeding values (EBV) in dairy cattle breeds with low numbers. In these breeds, few sires have progeny records, and genotyping cows can improve the accuracy of genomic EBV. The Guernsey breed is a small dairy cattle breed with approximately 14,000 recorded individuals worldwide. Predictions of phenotypes of milk yield, fat yield, protein yield, and calving interval were made for Guernsey cows from England and Guernsey Island using genomic EBV, with training sets including 197 de-regressed proofs of genotyped bulls, with cows selected from among 1,440 genotyped cows using different genotyping strategies. Accuracies of predictions were tested using 10-fold cross-validation among the cows. Genomic EBV were predicted using 4 different methods: (1) pedigree BLUP, (2) genomic BLUP using only bulls, (3) univariate genomic BLUP using bulls and cows, and (4) bivariate genomic BLUP. Genotyping cows with phenotypes and using their data for the prediction of single nucleotide polymorphism effects increased the correlation between genomic EBV and phenotypes compared with using only bulls by 0.163 +/- 0.022 for milk yield, 0.111 +/- 0.021 for fat yield, and 0.113 +/- 0.018 for protein yield; a decrease of 0.014 +/- 0.010 for calving interval from a low base was the only exception. Genetic correlation between phenotypes from bulls and cows were approximately 0.6 for all yield traits and significantly different from 1. Only a very small change occurred in correlation between genomic EBV and phenotypes when using the bivariate model. It was always better to genotype all the cows, but when only half of the cows were genotyped, a divergent selection strategy was better compared with the random or directional selection approach. Divergent selection of 30% of the cows remained superior for the yield traits in 8 of 10 folds. C1 [Jenko, J.; Eaglen, S. A. E.; Pong-Wong, R.; Woolliams, J.

TI Single-dose infusion of sodium butyrate, but not lactose, increases plasma beta-hydroxybutyrate and insulin in lactating dairy cows SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE butyrate; lactose; ruminal infusion; volatile fatty acid ID VOLATILE FATTY-ACIDS; RUMINAL BUTYRATE; FEEDING LACTOSE; MILK-PRODUCTION; METABOLISM; SHEEP; BLOOD; PERFORMANCE; PROPIONATE; SECRETION AB Several studies have identified beneficial effects of butyrate on rumen development and intestinal health in preruminants. These encouraging findings led to further investigations related to butyrate supplementation in the mature ruminant. However, the effects of elevated butyrate concentrations on rumen metabolism have not been investigated, and consequently the maximum tolerable dosage rate of butyrate has not been established. Therefore, the first objective of this work was to evaluate the effect of a short-term increase in rumen butyrate concentration on key metabolic indicators. The second objective was to evaluate the source of butyrate, either directly dosed in the rumen or indirectly supplied via lactose fermentation in the rumen. Jugular catheters were inserted into 4 ruminally fistulated Holstein cows in a 4 x 4 Latin square with 3-d periods. On d 1 of each period, 1 h after feeding, cows were ruminally dosed with 1 of 4 treatments: (1) 2 L of water (CON), (2) 3.5 g/kg of body weight (BW) of lactose (LAC), (3) 1 g/kg of BW of butyrate (1GB), or (4) 2 g/kg of BW of butyrate (2GB). Sodium butyrate was the source of butyrate, and NaCl was added to CON (1.34 g/kg of BW), LAC (1.34 g/kg of BW), and 1GB (0.67 g/ kg of BW) to provide equal amounts of sodium as the 2GB treatment. Serial plasma and rumen fluid samples were collected during d 1 of each period. Rumen fluid pH was greater in cows given the 1GB and 2GB treatments compared with the cows given the LAC treatment. Cows administered the 1GB and 2GB treatments had greater rumen butyrate concentrations compared with LAC. Those cows also had greater plasma butyrate concentrations compared with cows given the LAC treatment. Plasma P-hydroxybutyrate was greater and insulin tended to be greater for butyrate treatments compared with LAC. No difference in insulin was found between the 1GB and 2GB treatments. Based on plasma and rumen metabolites, singly infusing 3.5 g/kg of BW of lactose into the rumen is not as effective at providing a source of butyrate as compared with singly infusing 1 or 2 g/kg of BW of butyrate into the rumen. Additionally, rumen pH, rumen butyrate, plasma 3-hydroxybutyrate, glucose, and plasma butyrate were less affected in cows administered the 1GB treatment than in cows given the 2GB treatment. This finding suggests that singly dosing 1 g/kg of BW of butyrate could serve as the maximum tolerable concentration for future research. C1 [Herrick, K. J.; Hippen, A. R.; Kalscheur, K.

Effective interventions to consistently ameliorate EED are lacking. Objective: We tested whether a bundle of safe and affordable interventions would decrease EED and stunting over 12-24 wk in a cohort of rural Malawian children 12-35 mo old. Methods: This was a randomized, double-blind, placebo-controlled clinical trial in which the intervention group received a single dose of albendazole and 14 d of zinc at enrollment and after 20 wk. The intervention group also received a daily multiple micronutrient powder throughout the 24 wk of study. The primary outcomes were improvements in EED, as measured by the urinary lactulose-tomannitol ratio (L:M ratio) from dual-sugar absorption testing, and linear growth. Urinary L:M ratios and anthropometric measurements were evaluated after 12 and 24 wk of intervention and compared with a placebo group that did not receive any of these interventions. Results: A total of 254 children were enrolled at a mean age of 24 mo; 55% were female. Their mean weight-for-age z score was -1.5, and their mean length-for-age z score was -0 9. After 12 and 24 wk of study, increases in the L:M ratio did not differ between the intervention group (0.071 and 0.088 units, respectively) and the placebo group (0.073 and 0.080 units, respectively) (P = 0.87 and 0.19, respectively). Relative changes in length and weight also did not differ significantly between groups at any time point. Conclusion: The combined usage of albendazole, zinc, and a daily multiple micronutrient powder did not decrease EED or stunting in this population of agrarian children 12-35 mo old in rural Malawi. Alternative interventions to improve these diseases should be investigated. This trial was registered at clinicaltrials.gov as NCT02253095.

TI Defense traits in the long-lived Great Basin bristlecone pine and resistance to the native herbivore mountain pine beetle SO NEW PHYTOLOGIST LA English DT Article DE climate change; Dendroctonus ponderosae (mountain pine beetle); exaptation; Pinus balfouriana (foxtail pine); Pinus flexilis (limber pine); Pinus longaeva (Great Basin bristlecone pine); tree longevity ID SOUTHERN ROCKY-MOUNTAINS; BARK BEETLES; LODGEPOLE PINE; RANGE EXPANSION; CLIMATE-CHANGE; DENDROCTONUS-PONDEROSAE; CHEMICAL DEFENSES; WHITEBARK-PINE; PLANT DEFENSE; RESIN DEFENSES AB Mountain pine beetle (MPB, Dendroctonus ponderosae) is a significant mortality agent of Pinus, and climate-driven range expansion is occurring. Pinus defenses in recently invaded areas, including high elevations, are predicted to be lower than in areas with longer term MPB presence. MPB was recently observed in high-elevation forests of the Great Basin (GB) region, North America. Defense and susceptibility in two long-lived species, GB bristlecone pine (Pinus longaeva) and foxtail pine (P. balfouriana), are unclear, although they are sympatric with a common MPB host, limber pine (P. flexilis). We surveyed stands with sympatric GB bristlecone-limber pine and foxtail-limber pine to determine relative MPB attack susceptibility and constitutive defenses. MPB-caused mortality was extensive in limber, low in foxtail and absent in GB bristlecone pine. Defense traits, including constitutive monoterpenes, resin ducts and wood density, were higher in GB bristlecone and foxtail than in limber pine. GB bristlecone and foxtail pines have relatively high levels of constitutive defenses which make them less vulnerable to climate-driven MPB range expansion relative to other high-elevation pines. Long-term selective herbivore pressure and exaptation of traits for tree longevity are potential explanations, highlighting the complexity of predicting plant-insect interactions under climate change.

TI Strain-Specific Resistance to Potato virus Y (PVY) in Potato and Its Effect on the Relative Abundance of PVY Strains in Commercial Potato Fields SO PLANT DISEASE LA English DT Article ID RECOMBINANT STRAINS; UNITED-STATES; MOLECULAR CHARACTERIZATION; SEROLOGICAL PROPERTIES; MONOCLONAL-ANTIBODIES; PCR ASSAY; IDENTIFICATION; CULTIVARS; DISEASE; NTN AB Potato virus Y (PVY) is a serious threat to potato production due to effects on tuber yield and quality, in particular, due to induction of potato tuber necrotic ringspot disease (PTNRD), typically associated with recombinant strains of PVY. These recombinant strains have been spreading in the United States for the past several years, although the reasons for this continuing spread remained unclear. To document and assess this spread between 2011 and 2015, strain composition of PVY isolates circulating in the Columbia Basin potato production area was determined from hundreds of seed lots of various cultivars. The proportion of nonrecombinant PVY isolates circulating in Columbia Basin potato dropped ninefold during this period, from 63% of all PVY positive plants in 2011 to less than 7% in 2015. This drop in PVY was concomitant with the rise of the recombinant PVYN-Wi strain incidence, from less than 27% of all PVY-positive plants in 2011 to 53% in 2015. The proportion of the PVYNTN recombinant strain, associated with PTNRD symptoms in susceptible cultivars, increased from 7% in 2011 to approximately 24% in 2015. To further address the shift in strain abundance, screenhouse experiments were conducted and revealed that three of the four most popular potato cultivars grown in the Columbia Basin exhibited strain-specific resistance against PVY. Reduced levels of systemic movement of PVY in such cultivars would favor spread of recombinant strains in the field. The negative selection against the nonrecombinant PVY strain is likely caused by the presence of the Ny(tbr) gene identified in potato cultivars in laboratory experiments. Presence of strain-specific resistance genes in potato cultivars may represent the driving force changing PVY strain composition to predominantly recombinant strains in potato production areas.

Cal race 4 isolates contain a unique Tfo1 transposon insertion in the PHO gene that was not found in other F. oxysporum f. sp. vasinfectum genotypes. Based on this insertion, a multiplex polymerase chain reaction method was developed to detect the Cal race 4 pathogen. A panel of F. oxysporum f. sp. vasinfectum isolates representing different vegetative compatibility groups (VCG) and DNA sequence types was assembled to test the specificity of the detection method. In all, 16 of 17 Cal race 4 isolates produced a 583-bp amplicon; the other isolate produced a 396-bp amplicon reflecting the absence of the Tfo1 insertion. This isolate was a moderately virulent pathogen among Cal race 4 isolates. In total, 80 other F. oxysporum isolates associated with cotton and 11 other formae speciales of F. oxysporum produced only the 396-bp amplicon. The method also distinguished Cal race 4 isolates from India race 4 isolates and China race 7 isolates, which did not possess the unique Tfo1 insertion but otherwise had identical DNA sequences, and all belong to VCG0114. The method is capable of detecting the pathogen directly from infected stem tissues even before external symptom appears and, thus, provides an effective tool for timely identification of infested fields and seed lots, and should help reduce dissemination of Cal race 4 in the U.S. Cotton Belt.

In total, 97 isolates were recovered from stripe rust samples collected in Ethiopia in 2013 and 2014. These isolates were tested on a set of 18 Yr single-gene differentials for characterization of races and 7 supplementary differentials for additional information of virulence. Of 18 P. striiformis f. sp. tritici races identified, the 5 most predominant races were PSTv-105 (21.7%), PSTv-106 (17.5%), PSTv-107 (11.3%), PSTv-76 (10.3%), and PSTv41 (6.2%). High frequencies (>40%) were detected for virulence to resistance genes Yr1, Yr2, Yr6, Yr7, Yr8, Yr9, Yr17, Yr25, Yr27, Yr28, Yr31, Yr43, Yr44, YrExp2, and YrA. Low frequencies (<40%) were detected for virulence to Yr10, Yr24, Yr32, YrTr1, Hybrid 46, and Vilmorin 23. None of the isolates were virulent to Yr5, Yr15, YrSP, and YrTye. Among the six collection regions, Arsi Robe and Tiyo had the highest virulence diversities, followed by Bekoji, while Bale and Holeta had the lowest. Evaluation of 178 Ethiopian wheat cultivars and landraces with two of the Ethiopian races and three races from the United States indicated that the Ethiopian races were more virulent on the germplasm than the predominant races of the United States. Thirteen wheat cultivars or landraces that were resistant or moderately resistant to all five tested races should be useful for breeding wheat cultivars with resistance to stripe rust in both countries.

TI Genomics-Based Marker Discovery and Diagnostic Assay Development for Wheat Blast SO PLANT DISEASE LA English DT Article ID PATHOGEN MAGNAPORTHE-ORYZAE; PERENNIAL RYEGRASS; PYRICULARIA-GRISEA; RICE; PCR; POPULATIONS; TRITICUM; BRAZIL AB Wheat blast has emerged as a major threat to wheat production in South America. Although originally restricted to Brazil, the disease has since been observed in the neighboring countries of Argentina, Bolivia, and Paraguay and recently the pathogen, Magnaporthe oryzae Triticum pathotype, was isolated from infected wheat in Bangladesh. There is growing concern that the pathogen may continue to spread to other parts of the world, including the United States, where several M. oryzae pathotypes are endemic. M. oryzae pathotypes are morphologically indistinguishable and, therefore, must be characterized genotypically. Symptoms of wheat blast include bleaching of the head, which closely resembles the symptoms of Fusarium head blight, further complicating efforts to monitor for the presence of the pathogen in the field. We used a genomics-based approach to identify molecular markers unique to the Triticum pathotype of M. oryzae. One of these markers, MoT3, was selected for the development of a polymerase chain reaction (PCR)-based diagnostic assay that was evaluated for specificity using DNA from 284 M. oryzae isolates collected from a diverse array of host species. Conventional PCR primers were designed to amplify a 361-bp product, and the protocol consistently amplified from as little as 0.1 ng of purified DNA. The specificity of the MoT3-based assay was also evaluated using Fusarium spp. DNA, from which no amplicons were detected.

Strategies to manage SBR include the use of foliar fungicides. Fungicide types, the rate of product application, and the number and timing of applications are critical components for successful rust management. The objectives of this study were to determine i) the sensitivity of P. pachyrhizi isolates collected in the U.S. to a range of fungicides and ii) the reduction of fungal infection based on fungicide type and timing of applications on soybean. There were differences (P < 0.05) in effective concentration (EC50) values among the fungicides tested. Azoxystrobin had low EC50 values for both urediniospore germination and fungal sporulation on inoculated leaflets. There were differences (P < 0.05) in fungal sporulation for application times, fungicide treatments, and their interaction when the fungus was inoculated on plants. All application times and nearly all fungicide treatments reduced (alpha = 0.05) fungal infection compared with the nonfungicide control. Information on fungicide sensitivity of P. pachyrhizi isolates and the preventive and curative effects of different fungicides are important in the management of SBR. C1 [Twizeyimana, M.; Hartman, G.

The primary objective of this study was to characterize the 16 slow-growing Fusarium strains that were isolated from the roots of symptomatic plants. Molecular phylogenetic analyses of a portion of translation elongation factor 1-alpha (TEF1) and the nuclear ribosomal intergenic spacer region (IGS rDNA) indicated that the etiological agents were Fusarium brasiliense and a novel, undescribed Fusarium sp. This is the first report of F. brasiliense outside of Brazil and Argentina and the novel Fusarium sp. causing soybean SDS. Koch's postulates were completed for both fusaria on seven soybean cultivars that are commercially available in South Africa. Results of the pathogenicity experiment revealed that the strains of F. brasiliense and Fusarium sp. differed in aggressiveness to soybean, as reflected in differences in foliar symptoms, root rot, and reduction in shoot length. Cell free culture filtrates of the two soybean SDS pathogens from South Africa and two positive control strains of F. virguliforme from the United States induced typical SDS symptoms on susceptible soybean cultivars in a whole-seedling assay, indicating that they contained phytotoxins.

Early diagnosis is crucial for effective disease management and the implementation of Integrated Pest Management practices. However, a rapid protocol for the detection of low levels of airborne inoculum is still missing. We developed a pathogen-specific quantitative loop-mediated isothermal amplification (qLAMP) assay coupled with a spore trap system for rapid detection and quantification of airborne inoculum of the M. oryzae perennial ryegrass pathotype, and tested its suitability for implementation in GLS-infected turfgrass fields. In summer 2015, two perennial ryegrass plots were artificially inoculated with the pathogen, with four continuously running custom impaction spore traps placed in each plot. Sampling units were replaced daily and tested with the developed qLAMP assay, while plots were monitored for symptom development. Results confirmed that the qLAMP assay-trap system was able to detect as few as 10 conidia up to 12 days before. symptoms developed in the field. LAMP technology is particularly appropriate for field implementation by nontechnical users, and has the potential to be a powerful decision support tool to guide timing of fungicide applications for GLS management.

To facilitate detection of SqVYV, enzyme linked-immunosorbent assay (ELISA) and quantitative reverse-transcription polymerase chain reaction (qRT-PCR) diagnostic methods were developed. Both methods were capable of detecting SqVYV in a wide range of cucurbit hosts. ELISA was able to detect virus in infected host tissue diluted to at least 1:2,560, which was sufficient for detection in symptomatic squash and watermelon plants. The qRT-PCR method was capable of reliably detecting as few as 3.4 copies of a cloned fragment of SqVYV genomic RNA with an average cycle threshold (CO value of 36.4. The sensitivities and specificities for each detection method were estimated by latent class analysis for a set of inoculated squash and watermelon plants at two sampling scales. The scales were hierarchical, with individual plants representing the upper scale and samples from the plant representing the lower scale. The number of samples per plant varied from 1 to 8, and a plant was diagnosed positive if any of its samples tested positive. For all analyses, a cutoff C-t of 35 was chosen for qRT-PCR, which is approximately 2.5 cycles lower than the lowest C-t value achieved for mock-inoculated plants (presumed to be a false positive). qRT-PCR showed high sensitivities (>= 0.99) at both sampling scales for squash and watermelon, whereas the sensitivities for ELISA ranged from 0.58 to 0.76. The specificities for both tests were very similar (>= 0.94), with ELISA sometimes outperforming qRT-PCR. These diagnostic methods provide additional tools for the identification of SqVYV and management of SqVYV-induced watermelon vine decline.

TI PCR Multiplexes Discriminate Fusarium Symbionts of Invasive Euwallacea Ambrosia Beetles that Inflict Damage on Numerous Tree Species Throughout the United States SO PLANT DISEASE LA English DT Article ID CANKER DISEASE; CAUSAL AGENT; PITCH CANKER; PHYLOGENETIC DIVERSITY; GENE PREDICTION; SP NOV.; SOLANI; CIRCINATUM; COMPLEX; CALIFORNIA AB Asian Euwallacea ambrosia beetles vector Fusarium mutualists. The ambrosial fusaria are all members of the ambrosia Fusarium Glade (AFC) within the Fusarium solani species complex (FSSC). Several Euwallacea Fusarium mutualists have been introduced into nonnative regions and have caused varying degrees of damage to orchard, landscape, and forest trees. Knowledge of symbiont fidelity is limited by current identification methods, which typically requires analysis of DNA sequence data from beetles and the symbionts cultured from their oral mycangia. Here, polymerase chain reaction (PCR)-based diagnostic tools were developed to identify the six Fusarium symbionts of exotic Euwallacea spp. currently known within the United States. Whole-genome sequences were generated for representatives of six AFC species plus F. ambrosiwn and aligned to the annotated genome of F. euwallaceae. Taxon-specific primer-annealing sites were identified that rapidly distinguish the AFC species currently within the United States. PCR specificity, reliability, and sensitivity were validated using a panel of 72 Fusarium isolates, including 47 reference cultures. Culture-independent multiplex assays accurately identified two AFC fusaria using DNA isolated from heads of their respective beetle partners. The PCR assays were used to show that Euwallacea validus is exclusively associated with AF-4 throughout its sampled range within eastern North America. The rapid assay supports federal and state agency efforts to monitor spread of these invasive pests and mitigate further introductions. C1 [Short, Dylan P.

TI Reducing grain storage losses in developing countries SO QUALITY ASSURANCE AND SAFETY OF CROPS & FOODS LA English DT Article DE food security; subsistence farmers; hermetic; grains; storage ID PROSTEPHANUS-TRUNCATUS; CARBON-DIOXIDE; MAIZE; DENSITY; OXYGEN AB We investigated the use of insecticide-treated material and modified atmosphere storage for reducing insect damage in stored maize. Results showed that insecticide-treated netting and insecticide-treated seed bags protected grain from insect damage, with the treated seed bags protecting grain for up to nine months if the grain was free from insects before storing. Covering the opening of grain storage containers with treated netting provided good control of stored-grain insects and may offer additional protection for grain silos being promoted in developing countries. Neither treated bags nor netting provided control if the grain contained insects before storage, thus emphasising the need to provide some means of controlling initial infestations at the time of storage when using bags or netting. We also showed that good control of insects can be achieved if the grain is stored in air-tight rigid containers that cannot be penetrated by insects or rodents. Hermetic plastic bags were readily penetrated by insects and rodents, thus negating their ability to protect grain from insects. We also showed that reducing oxygen levels through the use of a candle in stored environments does little to protect grain from insects. Modifying the atmosphere by reducing oxygen levels or raising carbon dioxide levels also provided good control of stored-grain pests. The solutions outlined in this paper offer farmers in developing countries methods to protect grain from stored-grain insects, thus reducing losses and improving food security. C1 [Dowell, F.

The tender 8-10 day leaves are juiced and the juice is consumed, added to smoothies, or consumed as a purchased wheatgrass dietary supplement in tablet, capsule and liquid forms. CD and other gluten related disorders cause both malabsorption of nutrients and an abnormal immune reaction to gluten. The only effective therapy is a lifelong gluten-free diet. Codex Alimentarius sets the gluten threshold level at 20 mg/ kg for gluten-free foods. This threshold has been adopted by many regulatory agencies such as European Commission and the US Food and Drug Administration. Consumption of wheatgrass extract has been reported to alleviate symptoms of ulcerative colitis and anaemia which are often symptoms of CD. This investigation utilised the R5 and G12 sandwich enzyme-linked immuno sorbent assays (ELISAs) to examine the potential gluten content of commercial and homegrown wheatgrass. Samples were spiked with commercial gliadin to assess recovery rates. Acceptable recovery rates ranging from 91 to 133% from gluten spiked samples were found. In all preparations the gluten content of wheatgrass leaf tissue was lower than the limit of detection and limit of quantification for both ELISAs as well as the thresholds defined by Codex Alimentarius standards. According to results presented here appropriately prepared wheatgrass contains no gluten and may have a role as a dietary supplement in a gluten-free diet. C1 [Adrianos, S.

Molecular approaches' on CE, however, have revealed that human cases are also commonly caused by another species, Echinococcus canadensis. All indices for classification and standardization of CE pathology including available images, epidemiology, diagnostics and treatment are currently based largely on a mixture of infections which include at least E. granulosus s.s. and E. canadensis. Involvement of other species of Echinococcus in CE including E. ortleppi or otherwise cryptic diversity demonstrated recently in Africa requires further elucidation. Molecular identification of the causative species in CE cases is essential for better understanding of pathogenesis and disease. This article stresses the importance of molecular species identification of human CE as a foundation for re-evaluation of evidence-based epidemiology. (C) 2016 Elsevier B.V. All rights reserved.

However, varying gap size alone often does not meet diversity objectives and broader goals to address contemporary forest conditions. Recent research highlights the need to consider site factors and history, natural disturbance models, within-gap structure and recruitment requirements in addition to light resources for desired tree diversity. This synthesis brings together silvicultural developments and ecological literature on gap-based management, highlighting interactions with other factors such as microsite conditions, non-tree vegetation and more. We pose a revised concept for managers and researchers to use in prescriptions and studies focused on integrated overstory and understory manipulations that increase structural complexity within and around canopy openings.

TI A demographic study of the exponential distribution applied to uneven-aged forests SO FORESTRY LA English DT Article ID SIZE DISTRIBUTIONS; MATRIX MODELS; TREE GROWTH; MORTALITY; STANDS; RECRUITMENT; POPULATION; MANAGEMENT; DYNAMICS; RATES AB A demographic approach based on a size-structured version of the McKendrick-Von Foerster equation is used to demonstrate a theoretical link between the population size distribution and the underlying vital rates (recruitment, mortality and diameter growth) for the population of individuals whose diameter distribution is negative exponential. This model supports the conclusion that the negative exponential distribution as applied to balanced natural uneven-aged stands is a stable equilibrium model under appropriate assumptions. These assumptions include constant recruitment of stems into the smallest class that balances total mortality, and a simple relation between per capita mortality and diameter growth. A simple maximum likelihood-based solution to parameter estimation in the inverse problem is developed allowing the estimation of recruitment and mortality given reasonable sample of diameters, along with an estimate of population size and diameter growth rate. Two sets of stand dynamics equations are developed that are based on (i) the form of the underlying negative exponential distribution, and (ii) more generally, from the derivation of the McKendrick-Von Foerster equation. Applications of the methods and their assumptions are discussed with regard to both managed and old growth uneven-aged stands. Stands or forests that are close to negative exponential structure and are judged to be reasonably close to steady state will have vital rates that support this model. In contrast, the negative exponential is likely more important and applicable as a pragmatic target distribution when used in managed forests.

To that end, comprehensive assessment and testing of alternative volume and biomass models were conducted for individual tree models employed in the component ratio method (CRM) currently used in the US' National Greenhouse Gas Inventory. The CRM applies species-specific stem volume equations along with specific gravity conversions and component expansion factors to ensure consistency between predicted stem volumes and weights, and additivity of predicted live tree component weights to match aboveground biomass (AGB). Data from over 76 600 stem volumes and 6600 AGB observations were compiled from individual studies conducted in the past 115 years - what we refer to as legacy data - to perform the assessment. Scenarios formulated to incrementally replace constituent equations in the CRM with models fitted to legacy data were tested using cross-validation methods, and estimates of AGB were scaled using forest inventory data to compare across 33 states in the eastern US. Modifications all indicated that the CRM in its present formulation underestimates AGB in eastern forests, with the range of underestimation ranging from 6.2 to 17 per cent. Cross-validation results indicated the greatest reductions in estimation bias and root-mean squared error could be achieved by scenarios that replaced stem volume, sapling AGB, and component ratio equations in the CRM. A change in the definitions used in apportioning biomass to aboveground components was also shown to increase prediction accuracy. Adopting modifications tested here would increase AGB estimates for the eastern US by 15 per cent, accounting for 1.5 Pg of C currently unaccounted for in live tree aboveground forest C stock assessments. Expansion of the legacy data set currently underway should be useful for further testing, such as whether similar gains in accuracy can be achieved in estimates of regional or national-scale C sequestration rates.

The non-parametric k-nearest neighbours (k-NN) technique calculates predictions as linear combinations of observations for sample units that are nearest in a space of auxiliary variables to population units for which predictions are desired. Implementations of k-NN require four choices: a distance or similarity metric, the specific auxiliary variables to be used with the metric, the number of nearest neighbours, and a scheme for weighting the nearest neighbours. The study objective was to compare optimized k-NN configurations with respect to confidence intervals for airborne laser scanning-assisted estimates of mean volume or biomass per unit area for study areas in Norway, Italy, and the USA. Novel features of the study include a new neighbour weighting scheme, a statistically rigorous method for selecting feature variables, simultaneous optimization with respect to all four k-NN implementation choices and comparisons based on confidence intervals for population means. The primary conclusions were that optimization greatly increased the precision of estimates and that the results of optimization were similar for the k-NN configurations considered. Together, these two conclusions suggest that optimization itself is more important than the particular k-NN configuration that is optimized.

However, the estimation process is often expensive, laborious and sometimes imprecise because of small sample sizes relative to population variability. Remote sensing techniques are an option to assist in surveying large areas by providing data that can be related to the forest attribute of interest through mathematical models of relationships. Light Detection and Ranging (LiDAR) is a technology that can provide data that are closely related to forest wood volume and biomass. With these data, linear regression is often used to estimate forest attributes. If the relationship provides evidence of nonlinearity, a transformation in the variables can be considered. However, modern computation allows fitting nonlinear regression models without transformations of the variables. Nonlinear least squares (NLS) techniques also give more freedom to assure satisfaction of natural conditions such as non-negativity and/or lower and upper asymptotes. Like any estimation technique, NLS is subject to overfitting when using a large number of predictor variables. Because NLS is more computationally intensive than linear regression, stepwise selection techniques may require considerable programming effort. We compared three methods to select predictor variables for nonlinear models of relationships between forest attributes and LiDAR metrics, two of them based on genetic algorithms (GAs) and one based on random forest (RM). GAs were implemented to optimize a cost function that yields root mean square error or the Akaike Information Criterion (AIC), while RM was based on variable importance in decision trees. A model with the predictor variable most correlated with the response variable was also considered. We compared the results of overall estimation for two datasets using the model-assisted, generalized regression estimator and concluded that the combination of GAs and AIC was the most efficient and stable procedure for selection of variables. We attribute this result to the penalty that AIC applies to models with large numbers of variables, which leads to a more efficient model with a minimum loss of information.

In this study, we test the relationship between annual biomass estimated using shrub growth rings and metrics of seasonal growth derived from Moderate Resolution Imaging Spectroradiometer (MODIS) spectral vegetation indices (SVIs) for a small area of southern California chaparral to evaluate the potential for mapping biomass at larger spatial extents. These SVIs are related to the fraction of photosynthetically active radiation absorbed by the plant canopy, which varies throughout the growing season and is correlated with net primary productivity. The site had most recently burned in 2002, and annual biomass accumulation measurements were available from years 5 to 11 post-fire. We tested the metrics of seasonal growth using six SVIs: normalized difference vegetation index (NDVI), enhanced vegetation index (EVI), soil adjusted vegetation index (SAVI), normalized difference water index (NDWI), normalized difference infrared index 6 (NDII6), and vegetation atmospherically resistant index (VARI). Several of the seasonal growth metrics/SVI combinations exhibit a very strong relationship with annual biomass, and all SVIs show a strong relationship with annual biomass (R-2 for base value time series metric ranging from 0.45 to 0.89). Although additional research is required to determine which of these metrics and SVIs are the most promising over larger spatial extents, this approach shows potential for mapping early post-fire biomass accumulation in chaparral at regional scales.

In an effort to further our understanding of growth impairment in relation to mycotoxins and other risk factors, biospecimens from a cohort of children enrolled in the Bhaktapur, Nepal MAL-ED study were assessed for aflatoxin exposure at 15, 24, and 36 months of age. Exposure was assessed through a well-established serum biomarker, the AFB(1)-lysine adduct. In this manuscript, the levels of aflatoxin exposure in the Nepal cohort were compared with those observed in aflatoxin studies, with child growth parameters as a health outcome. Results from this preliminary analysis demonstrated chronic aflatoxin exposure in children residing in Bhaktapur with a geometric mean of 3.62 pg AFB(1)-lysine/mg albumin. The range of exposure in this population is similar to those in African populations where associations with aflatoxin biomarkers and poor child growth have been observed. Future work will analyze the relationships between aflatoxin levels, growth, and other risk factors collected by the MAL-ED study.

Conventional Armillaria inoculation assays use young saplings as hosts and consequently are cumbersome, frequently conducted outdoors, and take many years from establishment to analysis of infection. We have developed and evaluated a faster inoculation assay for Armillaria that uses herbaceous plants as hosts, is carried out in controlled conditions, and reduces experimental durations to 3 months. Plant species of known susceptibility to Armillaria and comparisons between virulent A. mellea and opportunistic A. gallica were used to validate the assay. Mortality and diagnostic symptoms of Armillaria root disease such as epiphytic rhizomorphs and mycelial fans were used to assess levels of infection. We also attempted to reduce assay preparation time by substituting woody inocula with agar inocula, but typical symptoms of Armillaria root disease were only observed on plants infected with woody inocula. Through our assay, we identified five new potential herbaceous hosts of Armillaria: Kniphofia hirsuta, Hordeum vulgare, Lobelia cardinalis, Nicotiana tabacum and Helenium hoopesii - further expanding the extensive list of plants with susceptibility to Armillaria and suggesting infection of herbaceous species may be more widespread than currently acknowledged.

There is some concern that redcedar will adversely impact stream discharge in these water-limited areas through increased transpiration and canopy interception in comparison to that of grasslands.We conducted a modeling study in the central reach of the North Canadian River basin between Lake Canton and Lake Overholser, located in central Oklahoma. The North Canadian River supplies about 25% of Oklahoma City's water supply. After model calibration, we simulated redcedar encroachment into the study area's grasslands in 10% increments to assess impact on stream discharge. We also performed simulations that represented complete removal of redcedar from the study area. Our simulations suggested that if all grasslands in the study area were replaced by redcedar, the simulated reduction in stream discharge would equal 112% of current municipal water demand and 89% of the projected 2060 demand. However, a more realistic conversion of 20% of grassland to redcedar would, according to our simulations, reduce stream discharge by an amount of water equivalent to 27% of the current water demand, or 21% of the projected 2060 demand. Our model simulations suggest that encroachment of redcedar into grasslands could have a detrimental effect on stream discharge, which could impact water availability on populations further downstream.

TI Differential Seasonal Steroid and Gonadotropin Expression in Full-Sibling Female Channel Catfish Maturing at Two or Three Years of Age under Normal and Accelerated Thermoperiods SO NORTH AMERICAN JOURNAL OF AQUACULTURE LA English DT Article ID TROUT SALMO-GAIRDNERI; ICTALURUS-PUNCTATUS; PLASMA ESTRADIOL-17-BETA; GENE-EXPRESSION; GONADAL CYCLE; HORMONE; FSH; TESTOSTERONE; CORTISOL; TIME AB The present study was designed to determine whether female Channel Catfish Ictalurus punctatus exhibiting accelerated maturation display similar steroid (estradiol and testosterone) and gonadotropin (luteinizing hormone and follicle-stimulating hormone [FSH] messenger RNA) profiles within the first reproductive period compared with full-sibling females that reached maturity 1 year later. The accelerated maturation (AM) fish were maintained under a shortened annual temperature cycle, consisting of 4 months in 26 degrees C water followed by 2 months at 13-14 degrees C, repeated for three cycles. In 2007, 2-year-old AM fish were 12 times more likely to spawn on any given day than the normal maturation (NM) fish. The 2-year-old NM group was 21 times more likely to spawn as 3-year-old fish in 2008 than in the previous year, 2007. In 2007, NM fish had higher body mass in January, March, and May and maintained higher gonadosomatic index (GSI). Two-year-old AM fish never had significantly higher levels of any measured variable than did 2-year-old NM fish. Compared with NM fish (2007), 3-year-old AM fish (2008) in their first reproductive period had significantly higher GSI, body mass, estradiol, and testosterone. The high spawning success of 2-year-old AM fish was not indicative of seasonal steroid and gonadotropin profiles relative to 3-year-old cohorts reared under standard conditions. However, seasonal levels during the first reproductive period of AM fish (2 years of age) were well below those of mature NM fish (3 years of age). The low plasma sex steroids and pituitary FSH and LH messenger RNA expression in fish undergoing accelerated maturation is perhaps the most interesting result of this study, since levels were sufficient enough to result in increased GSI and greater than 70% spawning success in these fish.

Hybrid catfish have unique production characteristics compared with Channel Catfish, and rapid adoption of the hybrid by fish farmers has outpaced research on appropriate management practices. This study was conducted to determine the effect of midsummer partial harvest of faster-growing fish on production characteristics in ponds with hybrid catfish in single-batch culture. Twelve 1.0-acre ponds were stocked with 10,000 year-class 1 hybrid catfish (similar to 0.12 lb/fish) in mid-March 2015. In August 2015, six random ponds were partially harvested to remove fish larger than similar to 1.25 lb using an in-pond, flexible-panel, grading sock. In October 2015, all ponds were completely harvested. Partial harvest of faster-growing fish removed similar to 26% of fish from ponds in August. Removal of faster-growing fish resulted in 0.9% of the total crop considered "out-of-size" (>4 lb/fish) and subject to discounts, compared with 2.1% of the fish from the control ponds. However, reduction of fish numbers by midsummer partial harvest reduced overall production by an average of 16% in the partial-harvest treatment compared with control ponds. Overall, partial harvest of faster-growing fish in midsummer reduced the overall biomass of discounted, out-of-size fish. Higher production in control ponds resulted in greater net revenue.

However, karst geology poses unique challenges in accurately simulating management impacts to both surface and groundwater hydrology. Two versions of the Soil and Water Assessment Tool (SWAT), Regular-SWAT and Topo-SWAT (which incorporates variable source area hydrology), were assessed for their robustness in simulating hydrology of the karstic Spring Creek watershed of Centre County, Pennsylvania, USA. Appropriate representations of surface water - groundwater interactions and of spring recharge - discharge areas were critical for simulating this karst watershed. Both Regular-SWAT and Topo-SWAT described the watershed discharge adequately with daily Nash-Sutcliffe efficiencies (NSE) ranging from 0.77 to 0.79 for calibration and 0.68-0.73 for validation, respectively. Because Topo-SWAT more accurately represented measured daily streamflow, with statistically significant improvement of NSE over Regular-SWAT during validation (p-value = 0.05) and, unlike Regular-SWAT, had the capability of spatially mapping recharge/infiltration and runoff generation areas within the watershed, Topo-SWAT was selected to predict nutrient and sediment loads. Total watershed load estimates (518 t nitrogen/year, 45 t phosphorus/year, and 13600 t sediment/year) were within 10% of observed values (-9.2% percent bias for nitrogen, 6.6% for phosphorous, and 5.4% for sediment). Nutrient distributions among transport pathways, such as leaching and overland flow, corresponded with observed values. This study demonstrates that Topo-SWAT can be a valuable tool in future studies of agricultural land management change in karst regions. Published by Elsevier B.V. C1 [Amin, M. G.

Standardized dual crop coefficient methods calculate both a non-stressed transpiration coefficient (K-cb) that is related to canopy cover, and a stress or transpiration reduction coefficient (K-s) that can be related to soil water deficit or other stress factors (e.g. disease). This study compares several remote sensing methods to determine K-cb and K-s and resulting evapotranspiration (ET) in a deficit irrigation experiment of corn (Zea mays L.) near Greeley, Colorado. Three methods were used to calculate K-cb (tabular, normalized difference vegetation index - NDVI, and canopy cover). Four canopy temperature based methods were used to calculate K-s: Crop Water Stress Index - CWSI, Canopy Temperature Ratio - Tcratio, Degrees Above Non-Stressed - DANS, Degrees Above Canopy Threshold - DACT. Crop ET predicted by these methods was compared to observation and water balance based ET measurements. Thermal indices DANS and DACT were calibrated to convert to K-s. Results showed that stress coefficient methods with less data requirements such as DANS and DACT are responsive to crop water stress as demonstrated by low RMSE of ET calculations, comparable to more data intensive methods such as CWSI. Results indicate which remote sensing methods are appropriate to use given certain data availability and irrigation level, in addition to providing an estimation of the associated error in ET.

TI Assessing FAO-56 dual crop coefficients using eddy covariance flux partitioning SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE FAO-56; Eddy covariance; Flux partitioning; Crop coefficients; Evapotranspiration ID IRRIGATED OLIVE ORCHARD; SAP FLOW TECHNIQUES; WATER-STRESS; REFERENCE EVAPOTRANSPIRATION; WEIGHING LYSIMETER; HAWAIIAN SUGARCANE; PLASTIC MULCH; WINTER-WHEAT; PEACH-TREES; SOIL AB Current approaches to scheduling crop irrigation using reference evapotranspiration (ET0) recommend using a dual-coefficient approach using basal (K-cb) and soil (K-e) coefficients along with a stress coefficient (K-s) to model crop evapotranspiration (ETc), [e.g. ETc = (K-s*K-cb +K-e)*ET0]. However, determining K-s, K-cb and K-e from the combined evapotranspiration (ET) is challenging, particularly for K-e, and a new method is needed to more rapidly determine crop coefficients for novel cultivars and cultivation practices. In this study, we partition eddy covariance ET observations into evaporation (E) and transpiration (T) components using correlation structure analysis of high frequency (10-20 Hz) observations of carbon dioxide and water vapor (Scanlon and Sahu, 2008) at three irrigated agricultural sites. These include a C4 photosynthetic-pathway species (sugarcane-Sacharum officinarum L.) and a C3 pathway species (peach-Prunus persica) under sub-surface drip and furrow irrigation, respectively. Both sites showed high overall K-c consistent with their height (>4 m). The results showed differences in K-e, with the subsurface drip-irrigated sugarcane having a low K-e (0.1). There was no significant relationship (r(2) <0.05) between root zone soil volumetric water content (VWC) in sugarcane and observed K-cb*K-s indicating that there was no stress (K-s =1), while the peach orchard showed mid-season declines, in K-cb*K-s when VWC declined below 0.2. Partitioning of K-c into K-cb and K-e resulted in a better regression (r(2) = 0.43) between the Normalized Differential Vegetation Index (NDVI) and K-cb in sugarcane than between NDVI and K-c (r(2) = 0.11). The results indicate the potential for correlation structure flux partitioning to improve crop ET coefficient determination by improved use of eddy covariance observations compared to traditional approaches of lysimeters and microlysimeters and sap flow observations to determine K-c, K-e, K-s, and K-cb.

A field study conducted at the University of Missouri Fisher Delta Research Center Marsh Farm during the 2013 and 2014 growing seasons investigated irrigation scheduling for sprinkler irrigated rice. Two irrigation timings were based on management allowed depletion (MAD) (MAD1: 10 mm application at a 12 mm estimated soil water deficit (SWD); MAD2: 15 mm application at a 19 mm estimated SWD). For each MAD treatment, three VRI settings represented 75, 100, and 125% of the target applications. Seven fewer irrigations were applied to MAD2 plots in 2013 and eleven fewer in 2014 but larger applications resulted in similar total application amounts. Neither treatment main effect was significant for yield in 2013, but there was a significant interaction, with differences among the % application treatments for MAD2. The % application main effect was significant for irrigation water use efficiency and there was a significant interaction. Yields were lower in 2014 than in 2013, which was expected given the late planting and soil compaction that resulted from land grading. Soil moisture data were inconsistent, and variability among the sensors led to few significant differences. Yield was significantly greater than the field average for only one treatment combination (MAD1 - 100%) and significantly lower for two (MAD2 - 75, 100%). Irrigation water use efficiency of two of the treatment combinations was significantly greater than the field average (MAD1 - 75%, MAD2 - 75%) while two were significantly lower (MAD1 - 125%, MAD2 - 125%). While the findings suggest that sprinkler irrigated rice performed equally well under a range of irrigation management, additional research is needed to validate these trends and develop improved guidelines for producers.

The Get to Know Program (Get to Know) is a multi-faceted program aimed at encouraging direct connection with nature through a variety of activities (observations of wildlife, hiking, creative arts, and special events), specifically among youth. Three studies assessed the effects of three Get to Know program activities on youth's implicit connectedness with nature (measured using a computer based game). Participants were youth recruited from southern California schools or youth organizations. Participation in the Get to Know Program's Creative Arts Contest was associated with increased implicit connectedness with nature. However, participation in the Get to Know Natural Treasure Adventure and Virtual Hike did not have an effect on connectedness with nature. Implications of these findings are important for agencies seeking to find effective tools for outreach focused on connecting participants with nature.

The maps, which are consolidated into an official web-based database, are derived from a framework of land classification, combined soil properties (both estimated and measured), and land management classification. The mapping was originally conceived as a practical tool to provide farmers and community planners with information on the basic soil resource for economic gain. For more than 75 years, the Natural Resources Conservation Service (formerly the Soil Conservation Service) has used land capability classification as a tool for planning conservation measures and practices on farms so that the land could be used without serious deterioration from erosion or other causes. The land capability classification is one of innumerable methods of land classification based on broad interpretations of soil qualities and other site and climatic characteristics. Modern soil surveys have evolved to portray soil interpretations and soil capability both geospatially and with data analysis. As the functionality of the National Soil Survey Information System (NASIS) and Soil Survey Geographic System (SSURGO) increases, the Natural Resources Conservation Service (NRCS) is advancing its interpretation program nationally to address security issues within the context of soil capability beyond land use and land cover. Soil capability for any potential human use or ecosystem service must be assessed within the context of soil properties, either measured or estimated. Using soil security as a framework (including capability, condition, capital, connectivity, and codification), soil interpretations of the US National Cooperative Soil Survey database may be tailored to address the questions of sustainability and climate change at local, regional, and global scales and to facilitate the transfer of technology to other countries and related scientific disciplines.

As we continue to grapple with a changing climate and more extreme weather events, regenerating the health and proper functioning of our nation's, and indeed world's, soil resource will markedly improve the capacity of soil to maintain or increase yield and yield stability, lower input costs, and contribute to other ecosystem services. This is true not only for croplands but also for pastures and native rangelands, orchards, and forests. To aid in moving forward initiatives to help farmers and ranchers improve the soil resource base, the USDA Natural Resources Conservation Service (NRCS) has created a new Soil Health Division (SHD). Personnel distributed across the country will facilitate soil health technical training and education for stakeholders, work with partners to standardize soil health assessments, promote soil health management systems as part of the conservation planning process, and facilitate implementation and long-term adoption of soil health management systems on our nation's agricultural lands. The new division will leverage skills, resources, technology, and partnerships to achieve these goals. C1 [Stott, Diane E.] USDA, NRCS Soil Hlth Div, W Lafayette, IN 47907 USA.

Soil survey units can be used to predict soil behavior and thus are useful for making management decisions and evaluating soil change. Traditionally, in the USA, soil survey mapping concepts have been developed with the dominant use of the landscape in mind. Current enhancement of soil survey includes documenting dynamic soil properties and soil change due to ecosystem management. Ecological sites are a concept used to describe "kinds of land" that have common potential kinds and amounts of vegetation and characteristic response to disturbance. In intensively managed (agronomic) systems, inputs (e.g., energy, fertilizer, irrigation water) can confound and homogenize vegetation indicators. In these situations, ecological site concepts, as constructed through state and transition models, can be differentiated based upon levels of soil function (indicated by dynamic soil properties) that occur as a result of the management (disturbance). Groupings and interpreting soil properties using an ecological site framework can serve as a useful tool for soil resource management and assessment and bring whole ecosystem insight into management decisions. Such organizational frameworks should provide information about both reference conditions and alternative management systems of soil functions or dynamic soil properties within an ecological site. Reference conditions might reflect either native or naturalized vegetation or the highest possible function that an ecological site could support. A framework for assessing soil condition in two ecological sites/soil types is examined. The capacity of each ecological site is different as indicated by soil carbon content and aggregate stability. This information allows for documentation of soil change (from reference to alternative states or management systems); it could also be used as a reference for soil health assessments and could be used to enhance soil survey with land use and management-specific information.

A biogeochemical model, DAYCENT, was used to simulate the effects of bioenergy Sorghum [Sorghum bicolor (L.) Moench] residue return on soil temperature and water content, soil organic carbon (SOC), and greenhouse gas (GHG) [carbon dioxide (CO2) and nitrous oxide (N2O)] emissions under bioenergy Sorghum production. Coefficient of determination (r(2)) was used to test model performance. Coefficients of determination between the observed and simulated soil temperature, soil water content, SOC, and annual CO2 and N2O emissions were 0.94, 0.81, 0.75, 0.97, and 0.0057, respectively, indicating that the DAYCENT model captured the major patterns of soil environmental factors and C turnover but was less accurate in estimatingN(2)O emissions. Compared with the simulated control (0 % residue return), the simulated 50 % residue return treatment had 7.77 %, 15.12 %, and 1.25 % greater SOC, annual CO2, and N2O emissions, respectively, averaged over 2 years' data (2010 and 2011). Similar patterns in the simulated outputs were also observed in our field trials, with percentages being 4.52 %, 15.98 %, and 12.89 %, respectively. The model also successfully reflected the daily GHG flux variation affected by treatments, management practices, and seasonal changes except for missing some high growing season fluxes. In addition, annual variations in the simulated outputs were comparable with field observations except the N2O emissions in the 50 % residue return treatment. Our study indicated that DAYCENT reasonably simulated the main effects of residue return on soil C turnover but underestimated N2O emissions.

Legume (hairy vetch [Vicia villosa Roth]), nonlegume (rye [Secale cereale L.]), a mixture of legume and nonlegume (hairy vetch and rye), and a control with no cover crop were grown in the winter to evaluate their effects on soil organic C (SOC), total N (STN), and nitrate-N (NO3-N) contents under bioenergy Sorghum from 2010 to 2013. Cover crop biomass and C and N contents were greater with vetch/rye mixture than rye and the control. The SOC at 5-15 and 15-30 cm was greater with vetch/rye than other treatments under forage Sorghum and at 0-5 cm and 5-15 cm was greater with vetch/rye and vetch than rye or the control under sweet Sorghum. The STN at 5-15 cm was greater with vetch/rye and the control than rye under forage Sorghum and at 0-5 and 5-15 cm was greater with vetch/rye and rye than the control under sweet Sorghum. Both SOC and STN at all depths increased linearly from 2010 to 2013, regardless of cover crops and Sorghum species. The NO3-N content at all depths varied with cover crops from 2011 to 2013. Bicultural cover crops, such as hairy vetch/rye mixture, have greater potential to sequester C and N than monocultures, such as hairy vetch and rye, or no cover crop due to greater crop residue returned to the soil under bioenergy Sorghum where aboveground biomass is harvested for bioenergy or feedstock.

This chapter explores those programs and ways in which they contribute toward National and International Soil Security. The two primary roles where FSA programs contribute are establishing minimum working land conservation requirements related to program support and conserving environmentally sensitive land. Most farms and ranches in the United States receive payments through at least one of the disaster assistance, safety net, and/or conservation programs administered through FSA, and all farms that participate in FSA farm programs and farm loan programs as well as other conservation and crop insurance programs administered by USDA are subject to conservation compliance provisions. Conservation compliance is focused on both preventing the loss of wetlands and ensuring that soil erosion is minimized through following sitespecific conservation plans. Celebrating its 30th anniversary, the Conservation Reserve Program (CRP) is by far FSA's flagship program related to soil conservation with about 24 million acres nationwide. In general, in exchange for a yearly rental payment, farmers voluntarily agree to remove environmentally sensitive land from agricultural production and plant species that improve environmental health and quality for the life of their 10-15-year contract. By targeting fragile cropland and placing these lands into protective conservation covers, CRP conserves wildlife habitat, improves water quality, and has reduced soil erosion by more than 8 billion tons and enhanced soil productivity significantly since 1986. CRP also sequesters more carbon on private lands than any other federally administered program and reduces greenhouse gases equivalent to removing 8.7 million cars from the road annually.

But in some. areas, these species, including C. microcarpa, are becoming rare arable plants because of agricultural intensification. Including them as crops could guarantee their conservation in agricultural systems. The fitness (i.e., vegetative and reproductive growth) of two populations of T. arvense, Teruel (Spain) and Minnesota (USA), and one for each C. sativa (Minnesota) and C. microcarpa (Teruel) was studied under different climates (semi-arid Mediterranean and continental temperate) over two seasons. Fitness of all species and populations was highly affected by the final plant density and the climatic conditions at each site and season. T. arvense from Spain and C. microcarpa showed more constant equilibrium in resource distribution patterns than those species or populations with American origin. The density variation between species, populations and seasons, which varied between 4 and 500 pl/m(2), indicate the importance of emergence for crop establishment of these species. Moreover, results showed that environmental conditions significantly affected crop development, i.e. plants were always higher in Spain than in the USA, indicating that mild winter sites may be better suited for their production than others. The establishment of T. arvense as a crop in a semi-arid region like that of North-eastern Spain is unlikely without irrigation, while C sativa could be a good option as a rotational crop regardless of irrigation. In the case of C microcarpa, although it could be cultivated, its final densities (hence germination and emergence) must be improved in order to establish it as a crop. (C) 2016 Elsevier B.V.

TI An evaluation study of pressure-compressed acoustic absorbers grown on agricultural by-products SO INDUSTRIAL CROPS AND PRODUCTS LA English DT Article DE Cotton; Mushrooms; Mycelium; Acoustic; By-products; Composite; Agricultural; Fiber; Boards ID CHARACTERISTIC IMPEDANCE AB This research examines the use of a novel new renewable resource in acoustic absorption applications. The new material being tested is based on a fungi that is grown on semi-hydrophobic agricultural by-product substrates such as cotton burs, switch-grass, rice straw, sorghum stalks, corn stalks and kenaf; to form a light-weight all-natural bio-composite board. The study examines the impact of a new post processing technique that converts the raw light-weight board into a much higher density compressed board that requires no additional glue or binder. The material traits of interest to this study are the acoustical absorption properties of this new high density variant. The study tested the boards over a range of compressed densities that resulted by increasing the compression force in a laboratory board press with a fixed temperature of 205 degrees Celsius for the following applied pressures {0, 2644, 3051, 3661, 4678N/m(2)} to achieve the following five density levels that were tested, {0.042 (uncompressed), 0.057, 0.086, 0.120, 0.169 g/cc}. Also included in the study were three reference materials {commercial acoustic ceiling tile, a cork flooring under-layment and birch plywood}. The acoustic properties of the material were characterized for acoustic absorption, in reflection and for through-transmission. The results of the study indicate this new class of densified mycelium based boards are a promising bio-based composite alternative for through-transmission acoustic shielding boards. Results show a progressive increase in sound shielding up to 0.087 g/cc after which further increases in density are statistically insignificant. This new material provides an all-natural, sustainable alternative to modern composite boards such as medium density fiber boards, "MDF" and oriented strand boards, "OSB". Published by Elsevier B.V.

Developing sound agronomic practices.for its production is key to optimizing its seed oil yield potential. Plant stand establishment of camelina has been problematic in some environments, which may be related to its small seed size and current recommendation for shallow sowing. Shallow sowing, can diminish seed to soil contact and expose seeds to large soil temperature and moisture fluctuations, which greatly affect germination and seedling emergence. A study was conducted in 2011 and 2012 on a Barnes loam soil in western Minnesota to examine the effects of sowing spring camelina at soil depths of 1, 2, and 4cm at sowing rates of 2, 3, and 6 kg ha(-1). Seedling emergence increased with sowing rate, but averaged across depths it had no effect on seed yield. Seedling emergence between the 1 and 2 cm sowing depths did not differ in 2012, while stands were reduced by an average of 29% at the 2 cm depth in 2011, but seed yields did not differ between the two sowing depths in either year. However, averaged across sowing rates, sowing at 4cm led to a 64% stand reduction and a significant 22%loss of yield compared with the 1 and 2 cm depths. Neither sowing depth nor rate affected seed oil content or harvest index. Results show that camelina has exceptional yield compensation capacity at low plant densities and can be sown deeper than commonly recommended (i.e., < 1.0 cm) without compromising yield in the northern Corn Belt. Sowing to a depth of 2 cm may be beneficial for certain soils prone to large temperature and moisture fluctuations. Published by Elsevier B.V. C1 [Gesch, R. W.; Dose, H.

TI High spatial resolution burn severity mapping of the New Jersey Pine Barrens with WorldView-3 near-infrared and shortwave infrared imagery SO INTERNATIONAL JOURNAL OF REMOTE SENSING LA English DT Article ID SPECTRAL INDEXES; FIRE SEVERITY; FOREST; LANDSAT; RATIO; DISCRIMINATION; VERSION; USA AB The WorldView-3 (WV-3) sensor, launched in 2014, is the first high-spatial resolution scanner to acquire imagery in the shortwave infrared (SWIR). A spectral ratio of the SWIR combined with the near-infrared (NIR) can potentially provide an effective differentiation of wildfire burn severity. Previous high spatial resolution sensors were limited to data from the visible and NIR for mapping burn severity, for example using the normalized difference vegetation index (NDVI). Drawing on a study site in the Pine Barrens of New Jersey, USA, we investigate optimal processing methods for analysing WV-3 data, with a focus on the pre-fire minus post-fire differenced normalized burn ratio (dNBR). Although the imagery, originally acquired with a 3.7 m instantaneous field of view, was aggregated to 7.5 m pixels by DigitalGlobe due to current licensing constraints, a slight additional smoothing of the data was nevertheless found to help reduce noise in the multi-temporal dNBR imagery. The highest coefficient of determination (R-2) of the regressions of dNBR with the field-based composite burn index was obtained with a dNBR ratio produced with the NIR1 and SWIR6 bands. Only a very small increase in R-2 was found when dNBR was calculated using the average of NIR1 and NIR2 for the NIR bands, and SWIR5 to SWIR8 for the SWIR bands. dNBR calculated using SWIR1 as the NIR band produced notably lower R-2 values than when either NIR1 or NIR2 were used. Differenced NDVI data was found to produce models with a much lower R-2 than dNBR, emphasizing the importance of the shortwave infrared region formonitoring fire severity. High spatial resolution dNBR data from WV-3 can potentially provide valuable information on finer details regarding burn severity patterns than can be obtained from Landsat 30 m data.

By exploiting a natural experiment hinging on the interaction between the probable onset of efforts to suppress MBD and the potential benefit to local communities' average health, this research finds that suppressing MBD explains at least 1.5% of the increase in global population growth since 1900. In Africa, estimates suggest 14% of growth is due to controlling MBD. Globally, the treatment effect is relatively uniform across the 20th century, while in Africa, population grew relatively faster after the widespread DDT spraying of the 1960s. Additionally, this research finds that different indices of historical malaria prevalence reveal complementary insights into the reduction of MBD and subsequent population growth. Robustness of the measured impacts are explored further using regional characteristics, such as topographic boundaries on the extent of Anopheles mosquitoes, as well as by controlling for other factors that could influence population growth.

In order to better understand the role selenium plays in breast cancer, 30 samples of tumor tissue were obtained from women with breast cancer and analyzed for selenium concentration, the levels of several selenium-containing proteins and the levels of the MnSOD anti-oxidant protein. Polymorphisms within the genes for these same proteins were determined from DNA isolated from the tissue samples. There was a wide range of selenium in these tissues, ranging from 24 to 854 ng/gm. The selenium levels in the tissues were correlated to the genotype of the SELENOP selenium carrier protein, but not to other proteins whose levels have been reported to be responsive to selenium availability, including GPX1, SELENOF and SBP1. There was an association between a polymorphism in the gene for MnSOD and the levels of the encoded protein. These studies were the first to examine the relationship between selenium levels, genotypes and protein levels in human tissues. Furthermore, the obtained data provide evidence for the need to obtain data about the effects of selenium in breast cancer by examining samples from that particular tissue type. (C) 2016 The Authors.

Therefore, sensitive, reliable and easy to use methods for the concentration, detection and quantification of microorganisms associated with the safety and quality of water are needed. In this study, we performed a field evaluation of an anion exchange resin-based method to concentrate male-specific (F+) RNA coliphages (FRNA), fecal indicator organisms, from diverse environmental waters that were suspected to be contaminated with feces. In this system, FRNA coliphages are adsorbed to anion exchange resin and direct nucleic acid isolation is performed, yielding a sample amenable to real-time reverse transcriptase (RT)-PCR detection. Matrix-dependent inhibition of this method was evaluated using known quantities of spiked FRNA coliphages belonging to four genogroups (GI, GII, GII and GIV). RT-PCR-based detection was successful in 97%, 72%, 85% and 98% of the samples spiked (10(6) pfu/l) with GI, GII, GIII and GIV, respectively. Differential FRNA coliphage genogroup detection was linked to inhibitors that altered RT-PCR assay efficiency. No association between inhibition and the physicochemical properties of the water samples was apparent. Additionally, the anion exchange resin method facilitated detection of naturally present FRNA coliphages in 40 of 65 environmental water samples (61.5%), demonstrating the viability of this system to concentrate FRNA coliphages from water.

The efficacy of these M. anisopliae formulations against the tick Rhipicephalus sanguineus s.l. was studied in laboratory under optimum or heat-stress conditions. The products were prepared in water [Tween (R) 80, 0.01 % (v/v)] or pure mineral oil. Conidia from Metarril (R) SP Organic suspended in water presented markedly delayed germination after heating to constant 40 degrees C (for 2, 4, or 6 h) compared to conidia suspended in mineral oil. Metarril (R) SP Organic suspended in oil and exposed to daily cycles of heat-stress (40 degrees C for 4 h and 25 degrees C for 19 h for 5 consecutive days) presented relative germination of conidia ranging from 92.8 to 87.2 % from day 1 to day 5, respectively. Conversely, germination of conidia prepared in water ranged from 79.3 to 39.1 % from day 1 to day 5, respectively. Culturability of Metarril (R) WP decreased from 96 % when conidia were cultured for 30 min prior to heat exposure (40 degrees C for 4 h) to 9 % when conidia were cultured for 8 h. Tick percent control was distinctly higher when engorged females were treated with oil suspensions rather than water suspensions, even when treated ticks were exposed to heat-stress regimen. Oil-based applications protected fungal conidia against heat-stress. Although Metarril (R) is not registered for tick control, it may be useful for controlling R. sanguineus, especially if it is prepared in mineral oil.

TI Toward mapping crop progress at field scales through fusion of Landsat and MODIS imagery SO REMOTE SENSING OF ENVIRONMENT LA English DT Article DE Crop growth stages; Phenology; Crop conditions; Crop progress; Crop yield; Data fusion; Time-series analysis ID TIME-SERIES; REFLECTANCE PRODUCTS; SURFACE REFLECTANCE; CLOUD SHADOW; PHENOLOGY; FOREST; MODEL; CORN; INFORMATION; ALGORITHM AB The ability to regionally monitor crop progress and condition through the growing season benefits both crop management and yield estimation. In the United States, these metrics are reported weekly at state or district (multiple counties) levels by the U.S. Department of Agriculture (USDA) National Agricultural Statistics Service (NASS) using field observations provided by trained local reporters. However, the ground data collection process supporting this effort is time consuming and subjective. Furthermore, operational crop management and yield estimation efforts require information with more granularity than at the state or district level. This paper evaluates remote sensing approaches for mapping crop phenology using vegetation index time-series generated by fusing Landsat and MODIS (Moderate Resolution Imaging Spectroradiometer) surface reflectance imagery to improve temporal sampling over that provided by Landsat alone. The case study focuses on an agricultural region in central Iowa from 2001 to 2014. Our objectives are 1) to assess Landsat-MODIS data fusion results over cropland; 2) to map crop phenology at 30 m resolution using fused surface reflectance data; and 3) to identify the relationships between remotely sensed crop phenology metrics and the crop progress stages reported by NASS. The results show that detailed spatial and temporal variability in vegetation development across this landscape can be identified using the fused Landsat-MODIS data. The mean difference (bias) in Normalized Difference Vegetation Index (NDVI) between actual Landsat observations and the fused Landsat-MODIS data, generated for Landsat overpass dates, is in the range of 0.011 to 0.028 for every year. The derived phenological metrics show distinct features for different crops and natural vegetation at field scales. Strong correlations are observed between remotely sensed phenological stages, based on NDVI curve inflection points, and the observed crop physiological growth stages from the NASS Crop Progress (CP) reports. The green-up dates detected from remote sensing data typically occurred during crop vegetative stages when 2-4 leaves were developed for both corn and soybeans, or about 1-3 weeks after the reported emergence dates when the plant were first visible to ground based observers. Despite being a lagging indicator, remotely sensed green-up can be used effectively to backcast emergence, e.g. as input to spatially distributed crop models. The differences in green-up date between corn and soybean were 8-10 days, consistent with the offset in emergence dates reported by NASS at district level. The reported harvest dates were typically about 2-3 weeks after the dormancy stage was detected via remote sensing for corn and about 1-2 weeks for soybeans. This suggests that probable harvest times for individual fields may be predicted 1-3 weeks ahead using remote sensing data. The results suggest that crop phenology and certain growth stages at field scales (30 m spatial resolution) can be linked and mapped by integrating imagery from multiple remote sensing platforms.

The airborne lidar is used to link ground observations of AGB to space lidar measurements. Two sets of models are generated, the first relating ground estimates of AGB to airborne laser scanning (ALS) measurements and the second set relating ALS estimates of AGB (generated using the first model set) to GLAS measurements. GLAS then, is used as a sampling tool within a hybrid estimation framework to generate stratum-, state-, and national-level AGB estimates. A two-phase variance estimator is employed to quantify GLAS sampling variability and, additively, ALS-GLAS model variability in this current, three-phase (ground-ALS-space lidar) study. The model variance component characterizes the variability of the regression coefficients used to predict ALS-based estimates of biomass as a function of GLAS measurements. Three different types of predictive models are considered in CONUS to determine which produced biomass totals closest to ground-based national forest inventory estimates - (1) linear (LIN), (2) linear-no-intercept (LNI), and (3) log-linear. For CONUS at the national level, the GLAS LNI model estimate (23.95 +/- 0.45 Gt AGB), agreed most closely with the US national forest inventory ground estimate, 24.17 +/- 0.06 Gt, i.e., within 1%. The national biomass total based on linear ground-ALS and ALS-GLAS models (25.87 +/- 0.49 Gt) overestimated the national ground-based estimate by 7.5%. The comparable log -linear model result (63.29 +/- 1.36 Gt) overestimated ground results by 261%. All three national biomass GLAS estimates, LIN, LNI, and log -linear, are based on 241,718 pulses collected on 230 orbits. The US national forest inventory (ground) estimates are based on 119,414 ground plots. At the US state level, the average absolute value of the deviation of LNI GLAS estimates from the comparable ground estimate of total biomass was 18.8% (range: Oregon, -40.8% to North Dakota, 128.6%). Log-linear models produced gross overestimates in the continental US, i.e., >2.6x, and the use of this model to predict regional biomass using GLAS data in temperate, western hemisphere forests is not appropriate. The best model form, LNI, is used to produce biomass estimates in Mexico. The average biomass density in Mexican forests is 53.10 +/- 0.88 t/ha, and the total biomass for the country, given a total forest area of 688,096 km(2), is 3.65 +/- 0.06 Gt. In Mexico, our GLAS biomass total underestimated a 2005 FAO estimate (4.152 Gt) by 12% and overestimated a 2007/8 radar study's figure (3.06 Gt) by 19%. (C) Published by Elsevier Inc.
