TI The effects of vitamin K1-rich plant foods on the efficacy of the

AB Voles can cause significant losses to agriculture and wood fibre production. California growers typically rely on baits containing chlorophacinone and diphacinone to reduce vole population densities, but the efficacy of those rodenticides has been decreasing. One hypothesis suggests that voles are consuming high levels of an antidote (vitamin K1) to the anticoagulants, contained within green leafy plants. We tested that hypothesis by first feeding Montane Voles (Microtus montanus) diets that were high in vitamin K1, and then providing the animals with either: (1) chlorophacinone-containing bait, (2) diphacinone-containing bait, or (3) a control diet. We found that the chlorophacinone-containing bait remained efficacious (100% mortality), whereas the diphacinone-containing bait had a much lower efficacy (60% mortality). When only the diphacinone-containing bait was presented, the efficacy was somewhat better (80%). We infer that a diet rich in vitamin K1 did not negate the effects of the chlorophacinone for voles, and so we recommend its continued use in California unless anticoagulant resistance is known to have developed in the vole population. We hypothesise that: (1) diphacinone has a relatively low efficacy against Montane Voles when compared to chlorophacinone, and (2) this lower efficacy could be further reduced by a vitamin K1-rich diet.

AB Mitigation of ecological damage caused by rangeland wildfires has historically been an issue restricted to the western United States. It has focused on conservation of ecosystem function through reducing soil erosion and spread of invasive plants. Effectiveness of mitigation treatments has been debated recently. We reviewed recent literature to conduct a meta-analysis of seeding after wildfires to determine if seedings may (1) protect ecosystems against soil erosion and (2) reduce invasion or abundance of undesirable nonnative plant species. Effectiveness of postfire seedings was examined in 8 erosion and 19 invasive species cases. Seeding has little effect on erosion during the first year after fire and is highly dependent upon initial establishment and coverage of species in successive years. Among all seeding cases, 28% reduced, 67% were neutral, and 5% increased invasive species abundance. Older seedings were more likely to show reductions in invasives than younger seedings. Seedings with high plant establishment were more likely to reduce invasives than those with low establishment. Studies are needed that examine (1) frequency of adequate establishment of postfire seedings and causal factors of success or failure, (2) long-term impacts of seeding along a range of initial establishment and concomitant plant coverage over time as it relates to erosion and abundance of invasive plant species, and (3) auxiliary treatments designed to increase likelihood of germination and establishment given the inevitable variability of environmental conditions. These studies would aid land managers in deciding when postfire treatments are required and their likely level of success.

AB The U.S. Department of Agriculture, Food Safety Inspection Service has determined that six non-O157 Shiga toxin-producing Escherichia call (STEC) serogroups (O26, O45, O103, O111, O121, and O145) are adulterants in raw beef. Isolate and phenotypic discrimination of non-O157 STEC is problematic due to the lack of suitable agar media. The lack of distinct phenotypic color variation among non-O157serogroups cultured on chromogenic agar poses a challenge in selecting colonies for confirmation. In this study, visible and near-infrared hyperspectral imaging and chemometrics were used to detect and classify non-O157 STEC serogroups grown on Rainbow agar O157. The method was first developed by building spectral libraries for each serogroup obtained from ground-truth regions of interest representing the true identity of each pixel and thus each pure culture colony in the hyperspectral agar-plate image. The spectral library for the pure-culture non-O157 STEC consisted of 2,171 colonies, with spectra derived from 124,347 of pixels. The classification models for each serogroup were developed with a k nearest-neighbor classifier. The overall classification training accuracy at the colony level was 99%. The classifier was validated with ground heel enrichments artificially inoculated with 10, 50, and 100 CFU/ml STEC. The validation ground-truth regions of interest of the STEC target colonies consisted of 606 colonies, with 3,030 pixels of spectra. The overall classification accuracy was 98%. The average specificity of the method was 98% due to the low false-positive rate of 1.2%. The sensitivity ranged from 78 to 100% due to the false-negative rates of 22, 7, and 8% for O145, O45, and O26, respectively. This study showed the potential of visible and near-infrared hyperspectral imaging for detecting and classifying colonies of the six non-O157 STEC serogroups. The technique needs to be validated with bacterial cultures directly extracted from meat products and positive identification of colonies by using confirmatory tests such as latex agglutination tests or PCR.

TI Determination of 5-Log Reduction Times for Escherichia coli O157:H7,

pH 3.5 or 3.8
SO JOURNAL OF FOOD PROTECTION
LA English
DT Article
ID ACID RESISTANCE; SURVIVAL
AB A critical factor in ensuring the safety of acidified foods is the establishment of a thermal process that assures the destruction of acid-resistant vegetative pathogenic and spoilage bacteria. For acidified foods such as dressings and mayonnaises with pH values of 3.5 or higher, the high water phase acidity (acetic acid of 1.5 to 2.5% or higher) can contribute to lethality, but there is a lack of data showing how the use of common ingredients such as acetic acid and preservatives, alone or in combination, can result in a 5-log reduction for strains of Escherichia coli O157:H7, Salmonella enterica, and Listeria monocytogenes in the absence of a postpackaging pasteurization step. In this study, we determined the times needed at 10 degrees C to achieve a 5-log reduction of E. coli O157:H7, S. enteric:a, and F. monocytogenes in pickling brines with a variety of acetic and benzoic acid combinations at pH 3.5 and 3.8. Evaluation of 15 different acid-pH combinations confirmed that strains of E. coli O157:H7 were significantly more acid resistant than strains of S. enterica and L. monocytogenes. Among the acid conditions tested, holding times of 4 days or less could achieve a 5-log reduction for vegetative pathogens at pH 3.5 with 2.5% acetic acid or at pH 3.8 with 2.5% acetic acid containing 0.1% benzoic acid. These data indicate the efficacy of benzoic acid for reducing the time necessary to achieve a 5-log reduction in target pathogens and may be useful for supporting process filings and the determination of critical controls for the manufacture of acidified foods.

AB :Recent investigations have found that Salmonella can be routinely recovered from peripheral lymph nodes (PLNs) of cattle presented for harvest. When contained within the PLNs, this foodborne pathogen is protected from currently used postharvest, in-plant intervention strategies and, therefore. PLNs harboring Salmonella may be a potential contaminant of ground beef. The objective of this work was to develop a challenge model that effectively and repeatedly results in Salmonella-positive PLNs. A 10-lancet skin-allergy instrument was inoculated with Salmonella, and calves were inoculated intra- and/or transdermally by applying the device over various ventral regions of the skin. Salmonella was successfully and predictably recovered from region-specific PLNs up to 8 days postchallenge. Furthermore, serotypes inoculated within specific regions were only recovered from the PLNs draining those regions. This model provides a method to predictably infect PLNs with Salmonella. Further, this model makes it possible to determine the duration of infection and to evaluate candidate interventions that may shorten the duration of infection.

AB Because challenge models to infect peripheral lymph nodes (PLNs) with Salmonella have not been reported, we performed a series of experiments to develop and refine challenge models to evaluate an intervention applied at the animal level and to provide initial estimates of efficacy of an intervention (i.e., a vaccine) to aid in the design of future studies. In each of four experiments, steers (control or vaccinated) were inoculated with Salmonella strains Montevideo or Newport, and in experiment IV, Salmonella Senftenberg was also used. Calves were euthanized 14 to 42 days postinoculation, and PLNs were collected. In the first experiment, calves were challenged with similar to 10(10) Salmonella cells, and few treatment differences were observed 14 days postchallenge. However, by day 21, Salmonella Newport was recovered from fewer vaccinated calves than control calves (P < 0.05). In experiment II, calves were challenged with similar to 10(7) Salmonella cells and, after two necropsies (14 and 28 days postchallenge), only one lymph node was Salmonella positive; therefore, the study was terminated. In experiment III, calves were again challenged with similar to 10(10) Salmonella cells, and no significant effect of vaccine was observed in calves challenged with Montevideo or Newport strains. A transdermal route of challenge was explored in experiment IV, using a 10-lancet, allergy testing instrument. Sixteen steers were challenged with either Salmonella Newport or Salmonella Montevideo (Salmonella Newport right legs; Salmonella Montevideo left legs), and all steers were challenged on the lower abdomen with Salmonella Senftenberg. Transdermal inoculation resulted in predictably Salmonella-positive PLNs, and a modest vaccine effect was detected. Because it is well tolerated by the calves and results in predictable and regionally specific Salmonella recovery from PLNs, the transdermal route of challenge may he preferred by researchers wishing to evaluate the impact of interventions designed to reduce the carnage of Salmonella in PLNs.

AB Salmonella enterica is a predominant foodborne pathogen that causes diarrheal illness worldwide. A potential method of inhibiting pathogenic bacterial growth in meat is through the introduction of plant-derived antimicrobials. The objectives of this study were to investigate the influence of heat (70 degrees C for 5 min) and subsequent cold storage (4 degrees C. up to 7 days) on the effectiveness of oregano and cinnamon essential oils and powdered olive and apple extracts against Salmonella enterica serovar Typhimurium DT104 in ground pork and to evaluate the activity of the most effective antimicrobials (cinnamon oil and olive extract) at higher concentrations in heated ground pork. The surviving Salmonella populations in two groups (heated and unheated) of antimicrobial-treated pork were compared. Higher concentrations of the most effective compounds were then tested (cinnamon oil at 0.5 to 1.0% and olive extract at 3, 4, and 5%) against Salmonella Typhimurium in heated ground pork. Samples were stored at 4 degrees C and taken on days 0, 3, 5, and 7 or enumeration of survivors. The heating process did not affect the activity of antimicrobials. Significant 1.3- and 3-log reductions were observed with 1.0% cinnamon oil and 5% olive extract, respectively, on day 7. The minimum concentration required to achieve >1-log reduction in Salmonella population was 0.8% cinnamon oil or 4% olive extract. The results demonstrate the effectiveness of these antimicrobials against multidrug-resistant Salmonella Typhimurium in ground pork and their stability during heating and cold storage. The most active formulations have the potential to enhance the microbial safety of ground pork.

AB The history of forest change processes is written into forest age and distribution and affects earth systems at many scales. No one data set has been able to capture the full forest disturbance and land use record through time, so in this study, we combined multiple lines of evidence to examine trends, for six US regions, in forest area affected by harvest, fire, wind, insects, and forest conversion to urban/surburban use. We built an integrated geodatabase for the contiguous U.S. (CONUS) with data spanning the nation and decades, from remote sensing observations of forest canopy dynamics, geospatial data sets on disturbance and conversion, and statistical inventories, to evaluate relationships between canopy change observations and casual processes at multiple scales. Results show the variability of major change processes through regions across decades. Harvest affected more forest area than any other major change processes in the North East, North Central, Southeast, and South central regions. In the Pacific Coast and Intermountain West, more forest area was affected by harvest than forest fires. Canopy change rates at regional scales confounded the trends of individual forest change processes, showing the importance of landscape scale data. Local spikes in observed canopy change rates were attributed to wind and fire events, as well as volatile harvest regimes. This study improves the geographic model of forest change processes by updating regional trends for major disturbance and conversion processes and combining data on the dynamics of fire, wind, insects, harvest, and conversion into one integrated geodatabase for the CONUS.

AB Forest ecosystems in the southern United States are dramatically altered by three major disturbances: timber harvesting, hurricane, and permanent land conversion. Understanding and quantifying effects of disturbance on forest carbon, nitrogen, and water cycles is critical for sustainable forest management in this region. In this study, we introduced a process-based ecosystem model for simulating forest disturbance impacts on ecosystem carbon, nitrogen, and water cycles. Based on forest mortality data classified from Landsat TM/ETM+images, this model was then applied to estimate changes in carbon storage using Mississippi and Alabama as a case study. Mean annual forest mortality rate for these states was 2.37%. Due to frequent disturbance, over 50% of the forest land in the study region was less than 30years old. Forest disturbance events caused a large carbon source (138.92 Tg C, 6.04 Tg C yr(-1); 1 Tg=10(12)g) for both states during 1984-2007, accounting for 2.89% (4.81% if disregard carbon storage changes in wood products) of the total forest carbon storage in this region. Large decreases and slow recovery of forest biomass were the main causes for carbon release. Forest disturbance could result in a carbon sink in few areas if wood product carbon was considered as a local carbon pool, indicating the importance of accounting for wood product carbon when assessing forest disturbance effects. The legacy effects of forest disturbance on ecosystem carbon storage could last over 50years. This study implies that understanding forest disturbance impacts on carbon dynamics is of critical importance for assessing regional carbon budgets.

AB In Sweden, subsurface transport of phosphorus (P) from agricultural soils represents the primary pathway of concern for surface water quality. However, there are mixed findings linking P in leachate with soil P and limited understanding of the interactive effects of applied P sources and soil test P on P leaching potential. Identifying soils that are susceptible to P leaching when manure is applied is critical to management strategies that reduce P loadings to water bodies. Intact soil columns (20 cm deep) from five long-term fertilization trials across Sweden were used in leaching experiments with simulated rainfall to explore the interactive effects of dairy cow (Bos taurus L.) manure application, soil test P and cropping system. Strong relationships were observed between ammonium lactate-extractable P in soil and dissolved reactive P (DRP) concentrations in leachate, although regression slopes varied across soils. For three soils, application of manure (equal to 21-30 kg P ha(-1)) to the soil columns significantly increased DRP leaching losses. The increase in DRP concentration was correlated to soil test P, but with wide variations between the three soils. For two soils leachate P concentrations after manure addition were independent of soil P status. Despite variable trends in P leaching across the different soils, P concentrations in leachate were always moderate from soils at fertilization rates equivalent to P removal with harvest. Results clearly stress the importance of long-term P balance to limit P leaching losses from Swedish agricultural soils.

AB Estimation of genetic population structure, diversity, and effective population size (N-e ) is important for defining meaningful conservation units and assessing genetic health. Recent conservation concerns in Alaska have highlighted the need for research on Eulachon Thaleichthys pacificus, a species about which relatively little is known. Therefore, genetic variation was assayed at 14 microsatellite loci to investigate the genetic population structure of Alaska Eulachon. This analysis revealed a low degree of genetic divergence (G(ST) = 0.005) that is structured by broad-scale northern and southern geographic regions. Overall, there is a significant correlation between genetic and geographic distances, suggesting that gene flow is geographically restricted and follows an isolation-by-distance (IBD) model. However, closer analysis reveals an absence of IBD within regions and that gene flow is primarily restricted by the geographic distance between regions, a pattern that better approximates the hierarchical island model. Gene flow is likely restricted between regions by a biogeographical barrier (i.e., the Alexander Archipelago). Alaska Eulachon have high levels of genetic diversity and relatively large N-e estimates of 3,535 and 2,823 for the northern and southern regions, respectively, although a large variance in reproductive success is likely responsible for a low N-e /N ratio. The observed genetic divergence suggests that it would be advantageous to manage the two regions separately to maintain productivity and evolutionary potential for Eulachon. Mixed-stock analysis (MSA) of simulated and known-origin mixtures supports the feasibility of regional stock separation. The northern and southern regions had MSA accuracies that were near or greater than 90% when fish from a single region comprised the mixtures. Further population structure may be present within regions, but additional analyses of collections across sampling years are necessary to clarify the microevolutionary processes.

AB Dams created by North American beavers Castor canadensis (hereafter, beavers) have numerous effects on stream habitat use by trout. Many of these changes to the stream are seen as positive, and many stream restoration projects seek either to reintroduce beavers or to mimic the habitat that they create. The extent to which beaver dams act as movement barriers to salmonids and whether successful dam passage differs among species are topics of frequent speculation and warrant further research. We investigated beaver dam passage by three trout species in two northern Utah streams. We captured 1,375 trout above and below 21 beaver dams and fitted them with PIT tags to establish whether fish passed the dams and to identify downstream and upstream passage; 187 individual trout were observed to make 481 passes of the 21 beaver dams. Native Bonneville Cutthroat Trout Oncorhynchus clarkii utah passed dams more frequently than nonnative Brown Trout Salmo trutta and nonnative Brook Trout Salvelinus fontinalis. We determined that spawn timing affected seasonal changes in dam passage for each species. Physical characteristics of dams, such as height and upstream location, affected the passage of each species. Movement behaviors of each trout species were also evaluated to help explain the observed patterns of dam passage. Our results suggest that beaver dams are not acting as movement barriers for Bonneville Cutthroat Trout or Brook Trout but may be impeding the movements of invasive Brown Trout.

AB There is growing urgency to enhance the sustainability of existing and emerging cities. The science of ecology, especially as it interacts with disciplines in the social sciences and urban design, has contributions to make to the sustainable transformation of urban systems. Not all possible urban transformations may lead toward sustainability. Ecological science helps identify components of resilience that can favor transformations that are more sustainable. To summarize the dynamics and choices involved in sustainable,transformations, a "metacity" framework is presented, embracing ecological processes in cities as complementary to those involving society, power, and economy.

AB Here, we assess current stress in the freshwater system based on the best available data in order to understand possible risks and vulnerabilities to regional water resources and the sectors dependent on freshwater. We present watershed-scale measures of surface water supply stress for the coterminous United States (US) using the water supply stress index (WaSSI) model which considers regional trends in both water supply and demand. A snapshot of contemporary annual water demand is compared against different water supply regimes, including current average supplies, current extreme-year supplies, and projected future average surface water flows under a changing climate. In addition, we investigate the contributions of different water demand sectors to current water stress. On average, water supplies are stressed, meaning that demands for water outstrip natural supplies in over 9% of the 2103 watersheds examined. These watersheds rely on reservoir storage, conveyance systems, and groundwater to meet current water demands. Overall, agriculture is the major demand-side driver of water stress in the US, whereas municipal stress is isolated to southern California. Water stress introduced by cooling water demands for power plants is punctuated across the US, indicating that a single power plant has the potential to stress water supplies at the watershed scale. On the supply side, watersheds in the western US are particularly sensitive to low flow events and projected long-term shifts in flow driven by climate change. The WaSSI results imply that not only are water resources in the southwest in particular at risk, but that there are also potential vulnerabilities to specific sectors, even in the 'water-rich' southeast.

AB Permafrost is tightly coupled to the organic soil layer, an interaction that mediates permafrost degradation in response to regional warming. We analyzed changes in permafrost occurrence and organic layer thickness (OLT) using more than 3000 soil pedons across a mean annual temperature (MAT) gradient. Cause and effect relationships between permafrost probability (PF), OLT, and other topographic factors were investigated using structural equation modeling in a multi-group analysis. Groups were defined by slope, soil texture type, and shallow (<28 cm) versus deep organic (>= 28 cm) layers. The probability of observing permafrost sharply increased by 0.32 for every 10-cm OLT increase in shallow OLT soils (OLTs) due to an insulation effect, but PF decreased in deep OLT soils (OLTd) by 0.06 for every 10-cm increase. Across the MAT gradient, PF in sandy soils varied little, but PF in loamy and silty soils decreased substantially from cooler to warmer temperatures. The change in OLT was more heterogeneous across soil texture types-in some there was no change while in others OLTs soils thinned and/or OLTd soils thickened at warmer locations. Furthermore, when soil organic carbon was estimated using a relationship with thickness, the average increase in carbon in OLTd soils was almost four times greater compared to the average decrease in carbon in OLTs soils across all soil types. If soils follow a trajectory of warming that mimics the spatial gradients found today, then heterogeneities of permafrost degradation and organic layer thinning and thickening should be considered in the regional carbon balance.

AB Switchgrass (Panicum virgatum L.) is a perennial C4 grass that is being developed as a bioenergy crop because it has high production yields and suitable agronomic traits. Five switchgrass biomass samples from upland and lowland switchgrass ecotypes harvested at different stages or maturity were used in this study. Switchgrass samples contained 317.0-385.0gglucans/kg switchgrass dry basis (db) and 579.3-660.2g total structural carbohydrates/kg switchgrass, db. Carbohydrate contents were greater for the upland ecotype versus lowland ecotype and increased with harvest maturity. Pretreatment of switchgrass with dilute ammonium hydroxide (8%w/w ammonium loading) at 170 degrees C for 20min was determined to be effective for preparing switchgrass for enzymatic conversion to monosaccharides; glucose recoveries were 66.9-90.5% and xylose recoveries 60.1-84.2% of maximum and decreased with increased maturity at harvest. Subsequently, pretreated switchgrass samples were converted to ethanol by simultaneous saccharification and fermentation using engineered xylose-fermenting Saccharomyces cerevisiae strain YRH400. Ethanol yields were 176.2-202.0l/Mg of switchgrass (db) and followed a similar trend as observed for enzymatic sugar yields.

AB Plant disease resistance gene analog (RGA) markers were designed according to the conserved sequence of known RGAs and used to map resistance genes. We used genome-wide RGA markers for genetic analyses of structure and diversity in a global rice germplasm collection. Of the 472 RGA markers, 138 were polymorphic and these were applied to 178 entries selected from the USDA rice core collection. Results from the RGA markers were similar between two methods, UPGMA and STRUCTURE. Additionally, the results from RGA markers in our study were agreeable with those previously reported from SSR markers, including cluster of ancestral classification, genetic diversity estimates, genetic relatedness, and cluster of geographic origins. These results suggest that RGA markers are applicable for analyses of genetic structure and diversity in rice. However, unlike SSR markers, the RGA markers failed to differentiate temperate japonica, tropical japonica, and aromatic subgroups. The restricted way for developing RGA markers from the cDNA sequence might limit the polymorphism of RGA markers in the genome, thus limiting the discriminatory power in comparison with SSR markers. Genetic differentiation obtained using RGA markers may be useful for defining genetic diversity of a suite of random R genes in plants, as many studies show a differentiation of resistance to a wide array of pathogens. They could also help to characterize the genetic structure and geographic distribution in crops, including rice, wheat, barley, and banana.

AB Processes controlling streamflow generation were determined using geochemical tracers for water years 2004-2007 at eight headwater catchments at the Kings River Experimental Watersheds in southern Sierra Nevada. Four catchments are snow-dominated, and four receive a mix of rain and snow. Results of diagnostic tools of mixing models indicate that Ca2+, Mg2+, K+ and Cl- behaved conservatively in the streamflow at all catchments, reflecting mixing of three endmembers. Using endmember mixing analysis, the endmembers were determined to be snowmelt runoff (including rain on snow), subsurface flow and fall storm runoff. In seven of the eight catchments, streamflow was dominated by subsurface flow, with an average relative contribution (% of streamflow discharge) greater than 60%. Snowmelt runoff contributed less than 40%, and fall storm runoff less than 7% on average. Streamflow peaked 2-4weeks earlier at mixed rain-snow than snow-dominated catchments, but relative endmember contributions were not significantly different between the two groups of catchments. Both soil water in the unsaturated zone and regional groundwater were not significant contributors to streamflow. The contributions of snowmelt runoff and subsurface flow, when expressed as discharge, were linearly correlated with streamflow discharge (R-2 of 0.85-0.99). These results suggest that subsurface flow is generated from the soil-bedrock interface through preferential pathways and is not very sensitive to snow-rain proportions. Thus, a declining of the snow-rain ratio under a warming climate should not systematically affect the processes controlling the streamflow generation at these catchments.

AB The internal erosion of soil pipes can induce pipe collapses that affect soil erosion processes and landform evolution. The objective of this study was to determine the spatial distribution of pipe collapses in agricultural fields of Goodwin Creek watershed. Ground survey was carried out to detect pipe collapses, and the location, size and surface elevation was measured with differential GPS. A total of 143 of the 145 pipe collapses were found in cropland, and the density was approximately 0.58 collapses per hectare. The spatial distribution of pipe collapses was not uniform as pipe collapses were concentrated in the flat alluvial plains where the land use was dominated by cropland. One of the four parcels had 90% of the pipe collapses with a density of 7.7 collapses per hectare. The mean depth, area and volume of these pipe collapses were 0.12 m, 0.34 m(2) and 0.02 m(3), respectively, and all these properties exhibited a skewed distribution. The drainage area-slope gradient equation, which has been widely used for erosion phenomenon prediction, did not represent pipe collapses in this study as the coefficient of determination was <0.01. This is clear evidence that subsurface flow is not represented by surface topographic characteristics. The pipe collapses were found to intercept runoff, thereby reducing the slope length factor by 6% and the drainage area by 7%. Both of these factors can reduce the sheet and rill erosion; however, the increased subsurface flow could enhance ephemeral gully erosion. Published 2012.

AB Objective: To develop a measure of person-centered communication (PCC) and demonstrate feasibility for use in primary care child obesity interventions.
Methods: Helping Healthy Activity and Nutrition Directions was a primary care intervention for families of overweight or obese 5- to 8-year-old children. The PCC Coding System (PCCCS) was based on theory and a validated motivational interviewing instrument. The PCCCS provided global scores, and total, positive, and negative PCC utterance frequencies. Three trained coders tested reliability of the PCCCS on audio recordings of sessions with 30 families. Potential uses of the PCCCS were demonstrated.
Results: The PCCCS demonstrated good inter-rater reliability for utterance frequencies but not for global scores.
Conclusions and Implications: The PCCCS is a reliable and feasible measure of PCC utterances. More research is needed to improve inter-rater reliability of the PCC global scale. The PCCCS may be used in the future to test fidelity of PCC interventions.

AB Solioccasus polychromus gen. & sp. nov., the most brightly colored hypogeous fungus known, is described from Papua New Guinea and tropical northern Australia south into subtropical forests along the Queensland coast and coastal mountains to near Brisbane. Phylogenetic analysis of molecular data places it as a sister genus to Bothia in the Boletineae, a clade of predominantly ectomycorrhizal boletes. Ectomycorrhizal trees, such as members of the Myrtaceae (Eucalyptus, Corymbia, Lophostemon, Melaleuca spp.) and Allocasuarina littoralis, were present usually in mixture or in some cases dominant, so we infer some or all of them to be among the ectomycorrhizal hosts of S. polychromus.

AB Aspergillus section Aspergillus contains economically important, xerophilic fungi that are widely distributed in nature and the human environment and are known for their ability to grow on substrates with low water activity. The taxa were revised based on sequence data from four loci, PCR fingerprinting, micro- and macromorphology, and physiology. The number of taxa was reduced to 17 species, all of which can be distinguished with sequence data from either the caM or RPB2 locus. The original description of A. proliferans was supplemented by a description of its teleomorph. This species seems to be relatively common and often has been confused with A. glaucus. In addition, green sporulating isolates of A. niveoglaucus isolated from food and several other substrates are indistinguishable in phenotype from A. glaucus. A dichotomous key based on ascospore size and ornamentation and the ability to grow at specific combinations of temperature and water activity is provided for identification of species. In response to recent changes in the botanical code, we transferred the Eurotium species to Aspergillus and selected one name for each species.

TI Managing the almond and stone fruit replant disease complex with less
soil fumigant
SO CALIFORNIA AGRICULTURE
LA English
DT Article
ID MANAGEMENT
AB As much as one-third of California's almond and stone fruit acreage is infested with potentially debilitating plant parasitic nematodes, and even more of the land is impacted by Prunus replant disease (PRD), a poorly understood soilborne disease complex that suppresses early growth and cumulative yield in replanted almond and peach orchards. Preplant soil fumigation has controlled these key replant problems, but the traditional fumigant of choice, methyl bromide, has been phased out, and other soil fumigants are increasingly regulated and expensive. We tested fumigant and nonfumigant alternatives to methyl bromide in multiple-year replant trials. Costs and benefits were evaluated for alternative fumigants applied by shanks in conventional strip and full-coverage treatments and applied by shanks or drip in novel spot treatments that targeted tree planting sites. Short-term sudan-grass rotation and prudent rootstock selection were examined as nonfumigant approaches to managing PRD. Trial results indicated that integrations of the treatments may acceptably control PRD with relatively little soil fumigant.

AB A 5-year project to facilitate the adoption of strawberry production systems that do not use methyl bromide initially focused on fumigant alternatives and resulted in increased use of barrier films that reduce fumigant emissions. The focus shifted in year 3 to evaluating and demonstrating nonfumigant alternatives: soilless production, biofumigation, anaerobic soil disinfestation (ASD) and disinfestation with steam. In the 2010-2011 strawberry production season, fruit yields on substrates were comparable to fruit yields using conventional methods. Anaerobic soil disinfestation and steam disinfestation also resulted in fruit yields that were comparable to those produced using conventionally fumigated soils. Additional work is in progress to evaluate their efficacy in larger-scale production systems in different strawberry production districts in California.

TI Fumigant emission reductions with TIF warrant regulatory changes
SO CALIFORNIA AGRICULTURE
LA English
DT Article
ID 1,3-DICHLOROPROPENE; CHLOROPICRIN; SOIL
AB With methyl bromide's phase-out, most growers have turned to alternative fumigants, particularly 1,3-dichloropropene (1,3-D) and chloropicrin. These alternatives are tightly regulated because they are classified as toxic air contaminants and volatile organic compounds; the latter combine with other substances to produce ground-level ozone (smog). Two ambient air monitoring studies were conducted to evaluate the potential of totally impermeable film (TIF) to reduce emissions from shank applications of chloropicrin and 1,3-D. In 2009, a study demonstrated that TIF reduced chloropicrin and 1,3-D peak emissions by 45% and 38%, respectively, but TIF did not reduce total emissions when it was cut after 6 days. In 2011, increasing the tarp period from 5 to 10 days decreased chloropicrin and 1,3-D peak emissions by 88% and 78%, and their total emissions by 64% and 43%, respectively. Concurrent dynamic flux chamber results corroborated the ambient air monitoring data. These studies provide regulatory agencies with mitigation measures that should allow continued fumigant use at efficacious application rates.

AB Forest nurseries in the western United States have relied for decades on methyl bromide to control soilborne pests. Numerous studies have investigated alternative fumigants, alternative application methods and nonfumigant approaches for their ability to reduce soilborne pest populations and produce quality, disease-free seedlings. We review the recent studies and identify where research is needed to assist the industry's transition away from methyl bromide. For the immediate, foreseeable future, an integrated approach combining nonfumigant and fumigant methods will provide the best strategy. Nevertheless, the industry may need to transition completely to container production if fumigant regulations become more restrictive.

TI Monitoring soil carbon will prepare growers for a carbon trading system
SO CALIFORNIA AGRICULTURE
LA English
DT Article
ID ORGANIC-CARBON; CLIMATE-CHANGE; CALIFORNIA; EMISSIONS; STABILIZATION
AB California growers could reap financial benefits from the low-carbon economy and cap-and-trade system envisioned by the state's AB 32 law, which seeks to lower greenhouse gas emissions statewide. Growers could gain carbon credits by reducing greenhouse gas emissions and sequestering carbon through reduced tillage and increased biomass residue incorporation. First, however, baseline stocks of soil carbon need to be assessed for various cropping systems and management practices. We designed and set up a pilot soil carbon and land-use monitoring network at several perennial cropping systems in Northern California. We compared soil carbon content in two vineyards and two orchards (walnut and almond), looking at conventional and conservation management practices, as well as in native grassland and oak woodland. We then calculated baseline estimates of the total carbon in almond, wine grape and walnut acreages statewide. The organic walnut orchard had the highest total soil carbon, and no-till vineyards had 27% more carbon in the surface soil than tilled vineyards. We estimated wine grape vineyards are storing significantly more soil carbon per acre than almond and walnut orchards. The data can be used to provide accurate information about soil carbon stocks in perennial cropping systems for a future carbon trading system.

AB Preplant fumigation with methyl bromide commonly is used in open-field perennial crop nurseries in California for control of plant-parasitic nematodes, pathogens and weeds. Because this fumigant is being phased out, alternatives are needed to ensure the productivity of the perennial crop nursery industry as well as the ornamental, orchard and vineyard production systems that depend on clean planting stock. As part of the USDA Area-Wide Pest Management Program for Integrated Methyl Bromide Alternatives, several perennial crop nursery projects were conducted in California from 2007 to 2011 to test and demonstrate registered alternative fumigants and application techniques that maximize performance and minimize environmental impacts. The project was designed to evaluate shank application and soil surface sealing methods intended to reduce aboveground emission and improve soil performance of 1,3-dichloropropene, a leading methyl bromide alternative for nurseries. In these garden rose and tree nursery experiments, 1,3-dichloropropene treatments performed well regardless of application techniques. In this article, we highlight recent research and discuss the significance and remaining challenges for adoption of methyl bromide alternatives in this unique nursery stock production system.

AB Anthocyanins are an important group of polyphenols that have health promoting properties. Analytical techniques for profiling anthocyanins have been widely reported in the last decade for in vitro and in vivo studies. A number of important technological advances in high-performance liquid chromatography (HPLC) and the introduction of the ultra high-performance liquid chromatography (UHPLC) have achieved significant gains in both the speed and the separation of anthocyanins in the past decade. Advancements in mass spectrometry, such as high-resolution and sequential collision mass spectrometry (HRMS and MSn) allow fast structural elucidation of food anthocyanins that play a very important role in food anthocyanin research. A significant increase in the number of studies has been reported for tandem MS, HRMS, and MSn based approaches for food analysis. This article provides an updated review of the application of liquid chromatography (HPLC and UHPLC) in combination with mass spectrometry (MS) for the study of food anthocyanins in recent years.

AB We studied the phylogeny of 22 accessions of Daunts and seven accessions in related genera, with DNA sequences from eight nuclear orthologs and one plastid (psbA/trnH) region. Maximum parsimony and maximum likelihood analyses of the concatenated data matrix of 7,212 aligned nucleotides provided excellent bootstrap support for many clades. Concordant with prior molecular results Pseudorlaya pumila was firmly imbedded within Daucus, as was Margottia gummifera, a new finding. All accessions of D. capillifolius, D. carota, and D. sahariensis formed a 2n = 18 clade with all other species within the Daucus clade with chromosome numbers of = 20, 22, and 44 (D. glochidiatus). Sister to the D. carota clade was a clade containing Margottia gummifera and Pseudorlaya pumila, sister to these species was D. crinitus, sister to all the above was D. muricatus, and sister to all of the above was a clade containing the remaining Daucus species.

TI FIBER AND YARN PROPERTIES FROM HIGH-SPEED ROLLER GINNING OF UPLAND
COTTON

DE Cottonseed quality; Fiber quality; Ring spinning; Roller ginning; Upland
cotton; Yarn quality
AB Selective breeding has improved upland cotton fiber properties. New high-speed roller ginning technology has advanced to the point that processing capacities have approached that of saw ginning. Producers seeking a better price for their upland cotton are interested in fiber property and textile mill performance data comparing cultivars processed by both saw and roller ginning. Three diverse cultivars, one of them stripper-harvested, were processed by saw ginning, conventional roller ginning, and high-speed roller ginning, with different levels of lint cleaning appropriate to each treatment. Samples were submitted for HVI and AFIS fiber property analysis. Ring-spun yarn from each treatment was tested. Results showed that the roller gin (conventional and high speed) produced fiber that was longer more uniform, had less short fiber, and fewer neps than the saw gin stand. Turnout, color grade, and leaf were not different among gin stand type. With respect to yarn properties, the conventional/high-speed roller gin had fewer thick places, but was higher in vegetable and foreign dark matter (contaminants), seed coats, and neps. The composition of neps changed as fiber was processed into yarn. The conventional/high-speed roller gin had fewer raw stock and card mat neps than the saw gin stand, but more neps in finished yarn. Differences jamong cultivar were prevalent throughout the study. In addition to differences in length, strength, and immature fiber content, the cultivar that was stripper harvested had double the trash content at harvest. There were differences in most fiber properties, but not yarn properties, among lint cleaner type. Roller gin lint cleaning was less aggressive than saw-type lint cleaning and had longer fiber, better uniformity, and fewer neps. Saw-type lint cleaning had better color and leaf grades, and less lint trash. There was no appreciable difference between the two types of roller gin lint cleaning used, but one saw-type lint cleaner as opposed to two was less damaging to the fiber Although roller ginned upland cotton is a niche market, textile mills value the higher quality obtained from roller ginning. Newer upland cultivars may make roller ginning a viable option in parts of the Unites States where roller ginning has not been available previously.

TI FLOW VARIABILITY OF AN AERIAL VARIABLE-RATE NOZZLE AT CONSTANT PRESSURES

DE Variable rate application; Nozzles; Aerial spraying; Agricultural
aviation
AB Variable-rate ground application systems have been in use for the past 15 years, but due to high application speeds, flow requirements, and aerodynamic considerations, variable-rate aerial nozzles have not been available until now. In 2006, Spray Target, Inc. (Rosemount, Minn.) released the VeriRateTM variable-rate aerial nozzle, the first commercially-available retrofit aerial nozzle of its kind. Conventional, fixed-orifice, hydraulic aerial nozzles are physically and practically limited to a doubling of flowrate. This new variable-orifice aerial nozzle promised a 10X rate change. Using a standard aircraft spray boom, this study quantified flowrate and flowrate variability from a set of 48 VeriRate nozzles at spray pressures ranging from 207-483 kPa (30-70 psi). Results indicated a 3.4 fold increase in flowrate change (2.35 to 8.10 L min(-1)) that could be achieved with this nozzle, but shy of the desired 10X rate change. Additionally, measured flowrate from the nozzles was dependent on the pressure-up sequence. Excess flow variability (CV>25%) between nozzles was found when spray pressure was gradually applied to the nozzles. Initially "spiking" the spray pressure to 483 kPa (70 psz) removed virtually all excess flow variability, except at 207 kPa (30 psi). Aerial applicators will be able to use the results from this study to make informed decisions when selecting variable-rate aerial nozzles.

AB Variable rate irrigation (VRI) systems are commercially available and can easily be retrofitted onto moving sprinkler systems. However, there are few reports on the application peiformance of such equipment. In this study, application uniformity of two center pivots equipped with a commercial VRI system were tested using fixed-plate sprinklers and a range of irrigation rates (100%, 80%, 70%, 50%, and 30%). Catch cans were arranged in transect, arcwise, and grid patterns to test the accuracy of application depth, and the uniformity of application in the direction of pivot travel and to investigate changes in uniformity along the pivot lateral between irrigation zones. The mean Heermann and Hein coefficient of uniformity (CUHH) and the mean lower-quarter distribution uniformity (DUlp) in the direction of pivot travel and along the pivot lateral were approximately 88% and 80%, respectively. Application uniformity was impacted at the border of adjacent irrigation zones along the pivot lateral when zones were applying different irrigation depths. While wind speed and direction did not appreciably decrease uniformity of application, it did impact absolute catch measurements. The mean evaporation and drift loss for all trials was 9.3%, and ranged from I% to 19%. Applying variable rate irrigation signcantly impacted uniformity of application for a distance 3 m wide between irrigation zones of different irrigation depths in spans 1-3 of the three-span, and a distance 6 to 9 m wide between irrigation zones in spans 5 and 6 of the six-span center pivot. Overall, the uniformity of application in the direction of pivot travel and within each irrigation zone was similar to values reported for other VRI sprinkler systems. The root mean square error between the prescribed and actual applied depth was <3.0 mm for catch collected in all spans along the pivot lateral and in the direction of pivot travel. This indicates that this commercial VRI is well suited for site-specific irrigation management. However; uniformity of application could be affected by the width of the irrigation management zones as well as sprinkler design and environmental factors.

AB A cost-effective approach was used to investigate the relationship between emission of the greenhouse gases (GHG), namely, CO2, CH4, and N2O and energy fluxes from a swine waste lagoon. Energy fluxes were calculated using the Penman method. The energy fluxes showed a diurnal pattern as expected of such fluxes. We found that air temperature and latent energy, lagoon surface temperature and solar radiation, as well as air temperature and wind speed can be used to predict for CO2, CH4, and N2O emissions, respectively. Comparison of observed and predicted emissions provided r(2) values of 0.49, 0.61, and 0.69 for CH4, N2O, and CO2, respectively. This research shows that long-term studies of GHG emissions and meteorological conditions are necessary to better understand the factors controlling the emissions of GHG in order to devise best management practices (BMP) for their control.

ID BULK-DENSITY
AB Peanut (arachis hypogaea L.) drying is an essential task preceding the grading process. Kernel moisture is one of five parameters used to establish the grade for a specific lot of peanuts, and it is imperative that peanuts be dried to a kernel moisture content <10.5% wet basis for grading and storage purposes. Today's peanut drying processes utilize decision support software based on modeling and require substantial human interaction to obtain kernel moisture content. These conditions increase the likelihood of peanuts being overdried or underdried. This research addresses the need for an automated controller with real-time, in-shell kernel moisture content determination capabilities. By using a microwave inoisture meter, developed within United States Department of Agriculture, Agricultural Research Service, the moisture content of the peanut kernel can be determined without having to shell the peanut pods. The kernel moisture content and atmospheric conditions serve as inputs to the controller, and thus, air temperature and drying time are controlled automatically. Such implementation reduces overdrying and underdrying, preserves quality of peanuts, and minimizes energy consumption through efficient control of the heater In this article, a quarter-scale drying system with automated control is discussed Kernel moisture content was determined in real time with a standard error of performance of 0.55% moisture when compared to the reference oven-drying method Such results show promise for large-scale implementation and testing.

AB Giant reed (Arundo donax) is an invasive weed that is native to the Old World. Tens of thousands of hectares of riparian habitat in the Rio Grande Basin (RGB) in Texas and Mexico have been heavily affected by invasions of Arundo. Additionally, many other watersheds across the southwestern United States have also been affected. Giant reed is being targeted for biological control because it displaces native vegetation and consumes water that could potentially be used for agricultural and municipal purposes, especially in areas with limited access to water. Finding the best-adapted insects for biological control involves locating the origin(s) of this plant. To narrow down the proximal source(s) of invasion of giant reed in the KGB, 10 microsatellite markers were developed. An analysis of 203 Old World and 159 North American plants, with an emphasis on the RGB, indicated a reduction in the allelic diversity in the introduced range compared with the Old World. Clonal assignment, neighbor joining, principal coordinates analyses, and STRUCTURE analyses were consistent and implied multiple introductions in North America, with one (likely clonal) lineage responsible for the invasion of the RGB, northern Mexico, and other parts of the southwestern United States. Although no identical matches with the RGB lineage were found in the Old World, several close matches were found on the Mediterranean coast of Spain.

AB Medusahead is a close relative of bread wheat that is native to Eurasia but has become a noxious, invasive weed in North America. Intergeneric use of primers for bread wheat simple-sequence repeat (SSR) markers was tested in medusahead in order to expand the pool of available genetic resources for study of this plant. Forty-two primer pairs were screened in medusahead, of which 29 produced visible bands in agarose gels. Amplicons from eight of these markers were sequenced and analyzed for the presence of SSRs and single-nucleotide polymorphisms (SNPs) among medusahead individuals from six populations in the western Great Basin. Of the eight sequenced amplicons, two contained SSRs, both of which were polymorphic and shared by the original bread wheat marker. Six of the eight markers combined to detect 33 SNP loci. BLAST comparisons of the eight amplicons revealed variable numbers of matching sequences from wheat and other grass species ranging from 0 to > 200 matches. Using data from the polymorphic loci, population genetic analysis of the six invasive medusahead populations indicated that they arose from two separate introductions with two additional subdusters possible within the two principal clusters. Extrapolating from these results, it is reasonable to expect that between 170 and 830 of the approximately 1,200 publicly available bread wheat SSRs would produce useful marker loci in medusahead.

AB Effective control techniques for pale swallowwort (PSW), an invasive herbaceous vine of old fields and forest understories, are limited. We conducted a 3-yr cutting and herbicide study on an adjacent old-field and forest understory site near Ithaca, NY, for control of PSW. Plants in experimental plots were cut in early July and cut again. or sprayed in late August for two seasons with the isopropylamine salt of glyphosate, or one of two rates (low or high) of either tridopyr triethylamine salt (i.e., SL, SH) or tridopyr butoxyethyl ester (EL, EH). The herbicide treatments were effective in reducing PSW cover, plant (stem) density, and aboveground biomass in the old-field site, but in several cases, only after 2 yr of cutting plus herbicide application. Only the cutting plus SH treatment did not reduce PSW cover relative to the unmanaged control in the forest understory and no treatment reduced biomass. In general, the cutting plus EH treatment was most effective in reducing PSW stem densities in the forest site. The most effective herbicide treatments differed between sites. Cutting plus EH reduced PSW cover by 84% and stem density (> 5 cm) by 86% in the old-field site. Cutting plus SH effectively decreased long and short (<= 5 cm) stem densities by 86 and 96%, respectively. Cutting plants twice during each of two seasons increased PSW cover by 301% and density of stems > 5 cm by 73% at this site. In the forest site, cutting plus glyphosate, or cutting plus EH or cutting plus SL and EL resulted in the greatest reductions in PSW cover (80, 76, 66, and 56%, respectively). Cover in plots cut twice per year decreased by 19%. The EH or SL treatments decreased long-stem densities by 78 and 71%, respectively. The EH treatment decreased short-stem density by 37%. These findings suggest that integrated techniques may control PSW but that effective management strategies may be habitat constrained.

AB Soil engineering by downy brome may be a facet of its competitiveness. Using rhizotrons in the greenhouse, we compared the growth and plant-soil relationships of downy brome grown in two field soil types: soil invaded for 12 yr by downy brome and a similar soil not yet invaded. For each soil type, downy brome was grown for two growth cycles. At harvest, root mass and soils were sampled at depths of 10, 40, and 80 cm (4, 16, and 32 in); aboveground biomass was also sampled. After the first growth cycle, downy brome grown in invaded soil had 250% greater aboveground biomass and nearly double the root mass per soil volume at 10 cm relative to downy brome grown in noninvaded soil; root mass per volume was similar at depths of 40 and 80 cm. For the second growth cycle, aboveground biomass declined, but was twice greater for downy brome grown in invaded soil; however, root mass per volume was similar between soil types for each depth. Soil attributes that positively related to aboveground biomass included bicarbonate-extractable P, DTPA (diethylentriamene pentaacetate)-extractable Mn, and solution-phase SC42- (80-cm depth). We conclude that the data support our hypothesis that downy brome has engineered the soil to increase its growth potential, but proof will require a more robust experimental design. Plant competition is affected by myriad interactions; however, a plant that can increase the availability of soil nutrients for itself and its growth potential, relative to competing plants, would appear to be at an advantage. The mechanistic underpinnings involved are inconclusive, but may involve increased availability of soil N, P, and Mn.

AB Throughout the world, the invasion of nonnative plants is an increasing threat to native biodiversity and ecosystem sustainability. Invasion is especially prevalent in areas affected by land transformation and disturbance. Surface mines are a major land transformation, and thus may promote the establishment and persistence of invasive plant communities. Using the Shale Hills region of Alabama as a case study, we assessed the use of landscape characteristics in predicting the probability of occurrence of six invasive plant species: sericea lespedeza, Japanese honeysuckle, Chinese privet, autumn-olive, royal paulownia, and sawtooth oak. Models were generated for invasive species occurrence using logistic regression and maximum entropy methods. The predicted probabilities of species occurrence were applied to the mined landscape to assess the probable prevalence of each species across the landscape. Japanese honeysuckle had the highest probable prevalence on the landscape (48% of the area), with royal paulownia having the lowest (less than 1%). Overall, 67% of the landscape was predicted to have at least one invasive plant species, with 20% of the landscape predicted to have two or more species, and 3% of the landscape predicted to have three or more species. Japanese honeysuckle, sericea lespedeza, privet, and autumn-olive showed higher occurrence on the reclaimed sites than across the broader region. We found that geospatial modeling of these invasive plants at this scale offered potential for management, both for identifying habitat types at risk and areas that need management attention. However, the most immediate action for reducing the prevalence of invasive plants on reclaimed mines is to remove invasive plants from the reclamation planting list. Three (sericea lespedeza, autumn-olive, and sawtooth oak) out of the six most common invasive plants in this study were planted as part of reclamation activities.

AB Desert grasslands of the southwestern United States have experienced an increase in the abundance and distribution of woody plant species over the past century. Shrub encroachment has caused a substantial loss of grasslands in the northern Chihuahuan Desert. The Chihuahuan Desert has also been invaded by Lehmann lovegrass, a fire-adapted species from southern Africa. In 1999, the U.S. Department of Agriculture Agricultural Research Service burned a remnant desert grassland to determine the effects of prescribed fire on shrub-perennial grass dynamics. The grassland also contained the nonnative perennial grass Lehmann lovegrass. I am reporting on a study that was initiated to determine whether prescribed burning would alter the vegetative community within and proximal to a Lehmann lovegrass-dominated patch. Cover of Lehmann lovegrass showed no significant response to the burn treatment. Of the dominant native species, only black grama and broom snakeweed had a significant year by treatment interaction. No species or growth form had a significant vegetation type by year by treatment interaction. After 6 yr, differences between burned and unburned transects were not significant for any species or growth form.

AB Simple, yet reliable models are needed to quantify soil organic carbon (SOC) changes for the wide diversity of agricultural management conditions in the United States. We compared the outputs of two relatively simple models currently available for farmers and government-financed farm support agencies: the Carbon (C) Management Evaluation Tool for Voluntary Reporting of Greenhouse Gases (COMET-VR) and the Soil Conditioning Index (SCI). Simulations were conducted for 18 locations throughout the United States for five soil textural regimes (loamy sand, sandy loam, silt loam, clay loam, and silty clay loam), three tillage management systems (conventional tillage [CT], minimum tillage [MT], and no tillage [NT]), and two crop rotations (wheat [Triticum aestivum L.]-potato [Solanum tuberosum L.] and wheat-four-year alfalfa [Medicago sativa L.] in western states and corn [Zea mays L.]-soybean [Glycine max L.] and corn-soybean-wheat in eastern states). Both models ranked SOC change as NT > MT > CT, whereby SOC change decreased with increasing soil disturbance with tillage However, models were divergent with regards to soil texture; SOC change was greater in coarse-textured than in fine-textured soils with COMET-VR, but SOC change was lower in coarse-textured than in fine-textured soils with SCI. For crop rotations, SOC change was greater or equal in simpler than in more complex rotation with COMET-VR, but smaller in simpler than in more complex rotations with SCI. Overall, SOC sequestration predicted by COMET-VR was positively related to SCI score, especially when accounting for differences in environmental conditions of a location. Our results suggest that both Models have value and limitations and that measures of SOC sequestration are predictable with these tools under a diversity of typical management conditions in the United States.

AB The incorporation of swine manure with tillage effectively reduces ammonia (NH3) emissions and conserves crop available nitrogen (N) but is not compatible with no-till and many other conservation tillage programs. Rolling-tine aerators potentially provide a means to enhance manure infiltration with limited disruption of the soil surface; however, the impact of the range of aerator configurations and manure placements has not been widely studied. We measured NH3 emissions, conducted presidedress nitrate (NO3) tests (PSNT), monitored corn (Zea mays L.) grain yield when swine manure was incorporated with combinations of two aerator toolbar offset angles (0 degrees and 10 degrees) and two manure placements (broadcast before aeration and banded behind aerator), and compared those measurements to unincorporated surface application and an unmanured control. Additional plots were established with five rates of mineral N fertilization to determine N response curve and estimate fertilizer N equivalent of the applied manure. Measurement of cumulative NH3 emissions using a dynamic chamber method showed that offsetting the aerator toolbar by 10 degrees reduced emissions by 65% to 75%, with both manure placements, compared to surface application. However, no consistent reductions in NH3 emissions were observed when the toolbar was not offset. While reduction in NH3 with the offset toolbar could conserve substantial amounts of plant available N, the soil disturbance caused by the offset tines would not be compatible with most conservation tillage programs. Presidedress NO3 test values increased when NH3 emissions were reduced. In 2009, both the angled and straight aerator treatments with manure banded behind the aerator resulted in significantly higher corn grain yield than all other treatments despite reductions in NH3 emissions only when the toolbar was angled. Correlation of yield from manure application treatments with the N response curve for multiple mineral N application rates showed a greater than expected response to manure application.Yield responses are an indication that aeration has benefits in addition to N conservation. We do not recommend the rolling-tine aerator if reducing NH3 emissions in conservation tillage is the primary goal, but future study into other yield-increasing benefits of aeration is needed.

AB Hybrid poplars have demonstrated high productivity as short rotation woody crops (SRWC) in the Midwest USA, and the hybrid aspen "Crandon" (Populus alba L. x P. grandidenta Michx.) has exhibited particularly promising yields on marginal lands. However, a key obstacle for wider deployment is the lack of economic returns early in the rotation. Alleycropping has the potential to address this issue, especially when paired with crops such as winter triticale which complete their growth cycle early in the summer and therefore are expected to exert minimal competition on establishing trees. In addition, well-placed fertilizer in low rates at planting has the potential to improve tree establishment and shorten the rotation, which is also economically desirable. To test the potential productivity of "Crandon" alleycropped with winter triticale, plots were established on five topographic positions with four different rates of fertilizer placed in the planting hole. Trees were then harvested from the plots after each of the first three growing seasons. Fertilization resulted in significant increases in branch, stem, and total aboveground biomass across all years, whereas the effects of topographic position varied by year. Allocation between branches and stems was found to be primarily a function of total aboveground biomass.

AB In 2010, the National Organic Program implemented a rule for the US stating that pasture must be a significant source of feed in organic ruminant systems. This article will focus on how the pasture rule has impacted the management, economics and nutritional value of products derived from organic ruminant systems and the interactions of grazing cattle with pasture forages and soils. The use of synthetic fertilizers is prohibited in organic systems; therefore, producers must rely on animal manures, compost and cover crops to increase and maintain soil nitrogen content. Rotational and strip grazing are two of the most common grazing management practices utilized in grazing ruminant production systems; however, these practices are not exclusive to organic livestock producers. For dairy cattle, grazing reduces foot and leg problems common in confinement systems, but lowers milk production and exposes cows to parasites that can be difficult to treat without pharmaceuticals. Organic beef cattle may still be finished in feedlots for no more than 120 days in the US, but without growth hormones and antibiotics, gains may be reduced and illnesses increased. Grazing reduces the use of environmentally and economically costly concentrate feeds and recycles nutrients back to the soil efficiently, but lowers the rate of beef liveweight gain. Increased use of pasture can be economically, environmentally and socially sustainable if forage use efficiency is high and US consumers continue to pay a premium for organic beef and dairy products.

AB Organic farming has been identified as promoting soil quality even though tillage is used for weed suppression. Adopting zero tillage and other conservation tillage practices can enhance soil quality in cropping systems where synthetic agri-chemicals are relied on for crop nutrition and weed control. Attempts have been made to eliminate tillage completely when growing several field crops organically. Vegetative mulch produced by killed cover crops in organic zero tillage systems can suppress annual weeds, but large amounts are needed for adequate early season weed control. Established perennial weeds are not controlled by cover crop mulch. Integrated weed management strategies that include other cultural as well as biological and mechanical controls have potential and need to be incorporated into organic zero tillage research efforts. Market crop performance in organic zero tillage systems has been mixed because of weed, nutrient cycling, and other problems that still must be solved. Soil quality benefits have been demonstrated in comparisons between organic conservation tillage and inversion tillage systems, but studies that include zero tillage treatments are lacking. Research is needed which identifies agronomic strategies for optimum market crop performance, acceptable levels of weed suppression, and soil quality benefits following adoption of organic zero tillage.

AB Many birds that are experiencing population declines require extensive tracts of mature forest habitat for breeding. Recent work suggests that at least some may shift their habitat use to early-successional areas after nesting but before migration. I used constant-effort mist netting in regenerating clearcuts (4-8 years postcut) and dense mature-forest understories to assess (1) whether most bird species of mature forests show habitat shifts after breeding; and (2), on the basis of several measures of condition, whether birds using early-successional habitats garnered any benefits or penalties, compared with those that remained in forests. I captured 3,845 individual birds of 46 species at four pairs of sites in mature Allegheny hardwood forests in northwestern Pennsylvania during the postbreeding periods of 2005-2008. Most, but not all, forest birds were captured at higher rates in cuts than in forests, and that pattern persisted through the postbreeding season. Using an information-theoretic approach, I found strong support for a species habitat interactive effect on both molt progression and body condition as measured by residuals from species-specific regression of mass on wing chord. Some, but not all, forest birds appeared to be in better condition when captured in cuts than when in forests. I found no support for a habitat effect on presence of fat or ectoparasites. My results reveal that habitat choice in the postbreeding season is correlated with physiological condition for a subset of forest birds, which suggests that the maintenance of such early-successional habitats in mature forest may benefit these species.

AB Xylella fastidiosa (Xf) causes diseases in many agricultural, horticultural, and landscape crops, including Pierce's disease (PD) of grapevines. PD has been a serious problem in scattered table, wine and raisin grape growing regions throughout California, as well as in Texas for more than 100 years. In this study, we evaluated the genetic variation in diversity and structure of Xf associated with PD of grapevines in California and Texas using simple sequence repeat (SSR) markers. The analysis revealed a high level of genetic diversity across the populations of Xf isolated from the grapevines from different viticulture locations or counties in California and Texas. Overall genetic diversity of Xf was detected comparatively high in Texas (0.835) than that in California (0.662). Hierarchical analysis of molecular variance (AMOVA) showed a significant genetic structure of Xf population between California and Texas. UPGMA clustering analysis and the Bayesian clustering algorithm using STRUCTURE consistently placed California and Texas Xf populations into two major genetic groups with no clear population structure within each state.

AB Citrus huanglongbing (HLB) has affected the citrus industry severely since it was first observed in south Florida in 2005. No published information is available on occurrence and in-grove distribution of HLB and its psyllid vector Diaphorina citri in north central Florida. D. citri and citrus leaf samples were collected from one organic and two conventional groves in Citra, FL, and from individual trees on the University of Florida (UF) campus in Gainesville to be tested for Candidatus Liberibacter asiaticus (Las) using qPCR. Las-positive D. citri samples were detected in Gainesville in 2007, and Las-positive trees were first found on the UF campus in October 2011. Las positive D. citri samples were obtained from symptomless trees in the organic grove in 2006 and 2007, and Las was first detected in leaf samples from asymptomatic orange trees in spring 2012. Trees in the conventional groves were Las-negative. HLB symptoms were first found in autumn 2012 in the organic grove and to a lesser extent in one conventional grove. HLB incidence was high along the northeastern edge of the groves. Semivariograms for within-row and across-row HLB spread were constructed using Las Ct values and tree distances. Monomolecular models were fit to the semivariance data. The range (=zone of influence) of HLB-infected trees was greater within rows (20 m) than across rows (13 m), suggesting that D. citri transmits HLB more readily within than across rows. Infection of conventional trees was probably delayed due to surrounding windbreaks. There was no relation between nutrient contents and HLB development.

AB Linden (Tilia platyphyllos var. laciniata) trees growing in Kaunas Botanical Garden and in the parks of Verkiu (Vilnius) and Belvederis estates in Lithuania exhibit laciniated, deformed leaves and yellowing of the veins. These trees had been planted in the parks, for the beauty of their "cut-out-elongated leaves", as a new variety of linden. However, use of the polymerase chain reaction (PCR), primed by phytoplasma universal primer pairs to amplify 16S rRNA gene sequences, followed by restriction fragment length polymorphism (RFLP) analysis, revealed that these linden trees were infected by phytoplasma strains belonging to subgroup 16SrI-B and to a new subgroup designated 16SrI-V, in the 'Candidatus Phytoplasma asteris' species of wall-less bacteria. The strains were further characterized by ribosomal protein gene sequence analysis. The experimental results have rekindled discussion of the possibility that a prized cultivar displaying unusual morphotype might be an invalid taxon. Is linden with laciniate-leaved branches a valid taxon (botanical variety), or simply a plant that has abnormal leaf morphotype caused by infection with a tiny wall-less bacterium?

AB Orthodox seeds are capable of withstanding severe dehydration. However, in the dehydrated state, Asn and Asp residues in proteins can convert to succinimide residues that can further react to predominantly form isomerized isoAsp residues upon rehydration (imbibition). IsoAsp residues can impair protein function and can render seeds nonviable, but PROTEIN ISOASPARTYL METHYLTRANSFERASE (PIMT) can initiate isoAsp conversion to Asp residues. The proteins necessary for translation upon imbibition in orthodox seeds may be particularly important to maintain in an active state. One such protein is the large, multidomain protein, Arabidopsis thaliana PLANT RNA HELICASE75 (PRH75), a DEAD-box helicase known to be susceptible to isoAsp residue accumulation. However, the consequences of such isomerization on PRH75 catalysis and for the plant are unknown. Here, it is demonstrated that PRH75 is necessary for successful seed development. It acquires isoAsp rapidly during heat stress, which eliminates RNA unwinding (but not rewinding) competence. The repair by PIMT is able to restore PRH75's complex biochemical activity provided isoAsp formation has not led to subsequent, destabilizing conformational alterations. For PRH75, an important enzymatic activity associated with translation would be eliminated unless rapidly repaired by PIMT prior to additional, deleterious conformational changes that would compromise seed vitality and germination.

AB Plants constantly monitor informational light signals using sensory photoreceptors, which include the phytochrome (phy) family (phyA to phyE), and adjust their growth and development accordingly. Following light-induced nuclear translocation, photoactivated phy molecules bind to and induce rapid phosphorylation and degradation of phy-interacting basic Helix Loop Helix (bHLH) transcription factors (PIFs), such as PIF3, thereby regulating the expression of target genes. However, the mechanisms underlying the signal-relay process are still not fully understood. Here, using mass spectrometry, we identify multiple, in vivo, light-induced Ser/Thr phosphorylation sites in PIF3. Using transgenic expression of site-directed mutants of PIF3, we provide evidence that a set of these phosphorylation events acts collectively to trigger rapid degradation of the PIF3 protein in response to initial exposure of dark-grown seedlings to light. In addition, we show that phyB-induced PIF3 phosphorylation is also required for the known negative feedback modulation of phyB levels in prolonged light, potentially through codegradation of phyB and PIF3. This mutually regulatory intermolecular transaction thus provides a mechanism with the dual capacity to promote early, graded, or threshold regulation of the primary, PIF3-controlled transcriptional network in response to initial light exposure, and later, to attenuate global sensitivity to the light signal through reductions in photoreceptor levels upon prolonged exposure.

AB Vitamin K exists in the food supply as phylloquinone, a plant-based form and as menaquinones (MKs), a collection of isoprenologues mostly originating from bacterial synthesis. Although multiple bacterial species used as starter cultures for food fermentations synthesize MK, relatively little is known about the presence and distribution of MK in the food supply and the relative contribution of MK to total dietary vitamin K intake. Dairy products may be a predominant source of dietary MK in many regions of the world, and there is recent interest in enhancing the MK content of dairy products through identification and selection of MK-producing bacteria in dairy fermentations. This interest is increased by emerging evidence that current dietary recommendations based on the classic role of vitamin K as an enzyme cofactor for coagulation proteins may not be optimal for supporting vitamin K requirements in extrahepatic tissues and that MK may have unique bioactivity beyond that as an enzyme cofactor. Observational studies have reported favorable associations between MK intake and bone and cardiovascular health. Although randomized trials have provided some evidence to support the beneficial effects of MK on bone, the evidence to date is not definitive, and randomized trials have not yet examined MK intake in relation to cardiovascular outcomes. Food production practices provide a means to enhance dietary MK availability and intake. However, parallel research is needed to optimize these production practices, develop comprehensive food MK content databases, and test hypotheses of unique beneficial physiological roles of MK beyond that achieved by phylloquinone.

AB Although plants have moved across the landscape in response to changing climate for millennia, projections of contemporary climate change suggest that forest tree species and populations will need to migrate faster than their natural ability. Therefore, climate change adaptation strategies, such as assisted migration, have gained attention since 2007. Effective implementation of assisted migration can only occur if target transfer guidelines are developed because our current seed transfer guidelines, established to guide the movement of plant materials, lack inherent spatial and temporal dynamics associated with climate change. This limitation restrains reforestation practitioners from making decisions about assisted migration. Lack of operating procedures, uncertainties about future climate conditions, risks associated with moving plants outside their current ranges, and existing policies have hampered formal actions in forest management and conservation. We review the current thinking on assisted migration of forest tree species and provide information that could facilitate implementation.

AB Introduction: The purpose of this study was to evaluate the relationships between first-trimester dietary factors and biochemical measures and subsequent risk of gestational hypertension.
Methods: This pilot study used a prospective design utilizing a convenience sample of nulliparous women enrolled at their first prenatal visit. A total of 57 women completed the study. Participants were divided into 2 groups for data analysis: normotensive pregnancy and gestational hypertension.
Results: Nearly one-quarter of study participants (22.8%) developed gestational hypertension, of whom84.6% had significant proteinuria meeting the criteria for preeclampsia. There were no significant differences inmicronutrient ormacronutrient dietary intakes between groups. Serumiron and zinc levels were lower for the gestational hypertension group compared with the normotensive pregnancy group (P =.01). Low serum zinc levels were related to a risk of developing gestational hypertension (adjusted odds ratio, 0.930; 95% confidence interval, 0.872-0.992).
Discussion: Ensuring adequate intake of zinc andmonitoring serum zinc levels in nulliparous pregnant women may help to prevent or contribute to early detection of gestational hypertension.

AB The aim of this paper was to reproduce the poisoning of Ipomoea verbascoidea in goats and describe the epidemiological, clinical and pathological aspects of spontaneous poisoning by this plant in Pernambuco. For this, we studied the epidemiology of the disease in seven municipalities in the semiarid region of the State. Three spontaneously poisoned goats were examined and then euthanized and necropsied (Group I). To reproduce the disease, the dried leaves of I. verbascoidea containing 0.02% swainsonine were supplied at doses of 4g/kg (0.8mg swainsonine/kg) to two groups of three animals. The goats in Group II received daily doses of the plant during 40 days and were euthanized on the 41st day of the experiment. Goats from Group III received daily doses of the plant during 55 days and were euthanized on the 120th day of the experiment. Other three goats constituted the control group (Group IV). In experimental groups, the brain lesions were evaluated by histopathology; additionally the cerebellar lesions were evaluated by morphometry, by measuring the molecular layer thickness, the number of Purkinje cells and the area of the cell bodies of these cells. The main clinical signs and microscopic lesions in goats poisoned were similar to those reported by swainsonine containing plants. In goats of GII and GIII, the first nervous signs were observed between 22th and 29th days; clinically, the disease developed by these animals was similar to the spontaneous cases. The goats of GIII did not recover from the neurologic signs. These results show that the consumption of the plant by 26-28 days after observation of the first clinical signs is enough to cause irreversible damage. By morphometric analysis, the molecular layer of the cerebellum of the goats of Group I and III were thinner than those of goats in the control group, and Purkinje neurons were atrophic. It is suggested that these changes are responsible for the neurological picture observed in goats that stop eating the plant and have sequelae of poisoning.

AB Water scarcity may appear to be a simple concept, but it can be difficult to apply to complex natural-human systems. While aggregate scarcity indices are straightforward to compute, they do not adequately represent the spatial and temporal variations in water scarcity that arise from complex systems interactions. The uncertain effects of future climate change on water scarcity add to the need for clarity on the concept of water scarcity. Starting with a simple but robust definitionthe marginal value of a unit of water wehighlight key aspects of water scarcity and illustrate its many biophysical and socioeconomic determinants. We make four central observations. First, water scarcity varies greatly across location, time, and a multitude of uses that are valued either directly or indirectly by society. Second, water scarcity is fundamentally a normative, anthropocentric concept and, thus, can and should be distinguished from the related, purely descriptive notion of water deficit. While such an anthropocentric perspective may seem limiting, it has the potential to encompass the vast range of interests that society has in water. Third, our ability to understand and anticipate changes in water scarcity requires distinguishing between the factors that affect the value or benefits of water from those affecting the costs of transforming water in space, time and form. Finally, this robust and rigorous definition of water scarcity will facilitate better communication and understanding for both policymakers and scientists.

AB New tools for controlling weeds would be useful for soybean production in organic systems. Air-propelled abrasive grit is one such tool that performs well for in-row weed control in corn, but crop safety in soybean is unknown. Responses to abrasion by corn-cob grit of soybean seedlings were examined at VE, VC, VU, V1, V2 (emergence, cotyledon, unifoliate, first trifoliate, and second trifoliate, respectively) and combinations of these growth stages, in both greenhouse and field settings. Seedling leaf areas and dry weights in greenhouse experiments were reduced by treatments that included abrasion at VC, with the primary effect expressed through reductions in the size of the unifoliate leaf. In the field, soybean stand also was reduced by grit applications at VC, especially if followed by a second application at VU or Vi. However, soybean yield was not reduced by grit applied at any soybean stage of growth. End-of-season weed dry weights did not differ from hand-weeded checks, and weeds did not impact soybean yields. Thus, abrasive grit for in-row weed control can be applied at least twice at VE through V2 growth stages without lowering soybean yield, but applications at VC probably should be avoided.

AB Free-standing two-dimensional (2D) nanostructures, exemplified by graphene and semiconductor nanomembranes, exhibit exotic electrical and mechanical properties and have great potential in electronic applications where devices need to be flexible or conformal to nonplanar surfaces. Based on our previous development of a substrate-free synthesis of large-area, free-standing zinc hydroxy dodecylsulfate (ZHDS) hexagonal nanomembranes, herein, we report a spontaneous phase transformation of ZHDS nanomembranes under extended reaction time. The hexagonal ZHDS sheets transformed into rectangular single crystal nanomembranes with sizes of hundreds of micrometers. They contain long-range-ordered zinc vacancies that can be fitted into an orthorhombic superlattice. A surplus of dodecylsulfate ions and a deficit of Zn2+ diffusion near the water surface are believed to be the factors that drive the phase transformation. The phase transformation starts with the formation of zinc vacancies at the topmost layer of the hexagonal hillock, and propagates along the spiral growth path of the initial hexagonal sheets, which bears a great resemblance to the classic "periodic slip process". Mechanical property characterization of ZHDS nanomembranes by nanoindentation shows they behave much like structural polymers mechanically due to the incorporation of surfactant molecules. We also developed a one-step exfoliation and dehydration method that converts ZHDS nanomembranes to ZnO nanosheets using n-butylamine. This work provides a further understanding of the growth and stability of ZnO-based nanomembranes, as well as advisory insight for the further development on solution-based synthesis of free-standing, single-crystalline 2D nanostructures.

AB Yerba mate tea (YMT) has a chemopreventive role in a variety of inflammatory diseases. The objective was to determine the capability of YMT and mate saponins to prevent azoxymethane (AOM)-induced colonic inflammation in rats. YMT (2% dry leaves, w/v, as a source of drinking fluid) (n = 15) and mate saponins (0.01% in the diet, at a concentration present in one cup of YMT) (n = 15) were given ad libitum to rats 2 weeks prior to AOM-injection until the end of the study; while control rats (n = 15) received a basal diet and drinking water. After 8-weeks of study, total colonic mucosa was scraped (n = 3 rats/group) and the remaining colons (n =12 rats/group) were cut into three equal sections and aberrant crypt foci (ACF) were analyzed. YMT reduced ACF formation from 113 (control group) to 89 (P < 0.05). YMT and mate saponins reduced the expression of proinflammatory molecules COX-2 and iNOS with concomitant reduction in p-p65 (P < 0.05). Immunohistochemical analysis of the formalin-fixed middle colons showed that YMT and mate saponins reduced the expression of p-p65(ser311) by 45.7% and 43.1%, respectively, in comparison to the control (P < 0.05). In addition, the expression of molecules upstream of NF-B such as p-IB- and p-GSK-3(Y216) was downregulated by YMT 24.7% and 24.4%, respectively (P < 0.05). Results suggest the mechanism involved in the chemopreventive effect of YMT and mate saponin consumption in AOM induced-colonic inflammation in rats is through inhibition of NF-B.

AB Anaerobic digestion (AD) is an economically viable manure treatment option for large dairies (>500 cows) in the U.S. However, roughly 90% of U.S. dairies have less than 200 cows, making this technology economically inaccessible to the vast majority of U.S. dairies. While there have been case studies of individual small dairies with anaerobic digesters, there are no comparative studies using cost data from these systems. The objectives of this study were to (1) determine the economic viability of small-scale U.S. digesters using cost data from nine existing 100 to 250-cow dairies and seven theoretical systems and (2) reevaluate the minimum size dairy farm needed for economically feasible AD in the U.S. Cash flow analysis results showed that total capital costs, capital costs per cow, and net costs per cow generally decreased with increasing herd size in existing systems. Among existing revenue streams, use of digested solids for bedding generated the highest revenue ($100 cow(-1) year(-1)), followed by biogas use for heating and/or electrical generation ($47 to $70 cow(-1) year(-1)) and CO2 credits ($7 cow(-1) year(-1)). No system had a positive cash flow under the assumed conditions (8% discount rate, 20-year term). However, six of the 16 systems had positive cash flows when 50% cost sharing was included in the analysis. Our results suggest that, with cost sharing, economically viable AD systems are possible on 250-cow dairies. Additional revenue streams, such as tipping fees for food waste, may reduce the minimum size to 100-cow dairies. (C) 2013 Elsevier Ltd. All rights reserved.

AB Corn stover has potential as a bioenergy feedstock in North America. We simulated production costs for stover harvest (three-pass and two-pass with baling or chopping, and single-pass with baling or chopping) and on-farm storage (outdoor and indoor bales, outdoor wrapped bales, and chopped stover in bags, bunks, or piles). For three- and two-pass harvest, chopping was 33-45% more expensive than baling. For baling and chopping, two-pass harvest was 25% cheaper than three-pass. Single-pass chopping harvests were on average 42% cheaper than three-pass or two-pass chopping. Single-pass baling was cheaper (4-31%) than multi-pass baling at low rates of stover collection, but more expensive (1-39%) at high rates of collection. For bales, outdoor storage of wrapped bales was cheapest. Outdoor, unwrapped bale storage, even with 12% dry matter loss, was cheaper than indoor storage. For chopped stover, storage in bags was always cheapest, followed by piles, and then bunkers. With harvest and storage together, there were four least cost systems: single-pass, ear-snap baling with wrapped bale storage; single-pass chopping with silage bag storage; and two-pass baling with wrapped-bale storage. A second group of harvest/storage systems was 25% more expensive, including single-pass, whole-plant baling with wrapped-bale storage; two-pass chopping with silage-bag storage; and three-pass baling with wrapped-bale storage. The three-pass chop harvest with silage bag storage was most expensive. Our analysis suggests all harvest and farm storage systems have tradeoffs and several systems can be economically and logistically viable. Published by Elsevier Ltd.

AB We provide a synthesis of the literature describing biochemical interactions between microorganisms and insects by way of microbial volatile organic compound (MVOC) production. We evaluated the functionality and ecological context of MVOC signals, and explored important metabolic pathways involved in MVOC production. The cosmopolitan distribution of microorganisms creates a context for frequent, and frequently overlooked, insect responses to microbial emissions. There are numerous instances of MVOCs being closely associated with insect feeding behaviors, but some MVOCs are also powerful repellants. Emissions from microorganisms in situ may signal aspects of habitat suitability or potential exposure to entomopathogens. In some ecosystems, bacterial or fungal volatiles can also incite insect aggregations, or MVOCs can resemble sexual pheromones that elicit mating and oviposition behaviors from responding insects. A single microorganism or MVOC can have different effects on insect behaviors, especially across species, ontogenies, and habitats. There appears to be a multipartite basis for insect responses to MVOCs, and complex tritrophic interactions can result from the production of MVOCs. Many biochemical pathways for behaviorally active volatile production by microbial species are conserved across large taxonomic groupings of microorganisms. In addition, there is substantial functional redundancy in MVOCs: fungal tissues commonly produce polyketides and short-chain alcohols, whereas bacterial tissues tend to be more commonly associated with amines and pyrazines. We hypothesize that insect olfactory responses to emissions from microorganisms inhabiting their sensory environment are much more common than currently recognized, and that these signals represent evolutionarily reliable infochemicals. Insect chemoreception of microbial volatiles may contribute to the formation of neutral, beneficial, or even harmful symbioses and provide considerable insight into the evolution of insect behavioral responses to volatile compounds.

AB We report here a first survey of insect orientation to fungal cultures and fungal volatiles from a community ecology perspective. We tested whether volatiles from a ubiquitous yeast-like fungus (Aureobasidium pullulans) are broadly attractive to insects in an agricultural landscape. We evaluated insect attraction to fungal cultures and synthetic compounds identified in fungal headspace (2-methyl-1-butanol, 3-methyl-1-butanol, 2-phenylethanol) in a spearmint (Mentha spicata L.) plantation. Three findings emerged: (1) 1,315 insects representing seven orders and 39 species oriented to traps, but 65 % of trapped insects were Dipterans, of which 80 % were hoverflies (Diptera: Syrphidae); (2) traps baited with A. pullulans caught 481 % more insects than unbaited control traps on average, and contained more diverse (Shannon's H index) and species rich assemblages than control traps, traps baited with Penicillium expansum, or uninoculated media; and (3) insects oriented in greatest abundance to a 1:1:1 blend of A. pullulans volatiles, but mean diversity scores were highest for traps baited with only 2-phenylethanol or 2-methyl-1-butanol. Our results show that individual components of fungal headspace are not equivalent in terms of the abundance and diversity of insects that orient to them. The low abundance of insects captured with P. expansum suggests that insect assemblages do not haphazardly orient to fungal volatiles. We conclude that volatiles from a common fungal species (A. pullulans) are attractive to a variety of insect taxa in an agricultural system, and that insect orientation to fungal volatiles may be a common ecological phenomenon.

AB Mycotoxins are fungal natural products that are toxic to vertebrate animals including humans. Microbes have been identified that enzymatically convert aflatoxin, zearalenone, ochratoxin, patulin, fumonisin, deoxynivalenol, and T-2 toxin to less toxic products. Mycotoxin-degrading fungi and bacteria have been isolated from agricultural soil, infested plant material, and animal digestive tracts. Biotransformation reactions include acetylation, glucosylation, ring cleavage, hydrolysis, deamination, and decarboxylation. Microbial mycotoxin degrading enzymes can be used as feed additives or to decontaminate agricultural commodities. Some detoxification genes have been expressed in plants to limit the pre-harvest mycotoxin production and to protect crop plants from the phytotoxic effects of mycotoxins. Toxin-deficient mutants may be useful in assessing the role of mycotoxins in the ecology of the microorganisms.

TI Combining Mutualistic Yeast and Pathogenic Virus - A Novel Method for

AB The combination of a pathogenic virus and mutualistic yeasts isolated from larvae of codling moth Cydia pomonella is proposed as a novel insect control technique. Apples were treated with codling moth granulovirus (CpGV) and either one of three yeasts, Metschnikowia pulcherrima, Cryptococcus tephrensis, or Aureobasidium pullulans. The combination of yeasts with CpGV significantly increased mortality of neonate codling moth larvae, compared with CpGV alone. The three yeasts were equally efficient in enhancing the activity of CpGV. The addition of brown cane sugar to yeast further increased larval mortality and the protection of fruit against larvae. In comparison, without yeast, the addition of sugar to CpGV did not produce a significant effect. A field trial confirmed that fruit injury and larval survival were significantly reduced when apple trees were sprayed with CpGV, M. pulcherrima, and sugar. We have shown earlier that mutualistic yeasts are an essential part of codling moth larval diet. The finding that yeast also enhances larval ingestion of an insect-pathogenic virus is an opportunity for the development of a novel plant protection technique. We expect the combination of yeasts and insect pathogens to essentially contribute to future insect management.

AB Injury to peach, Prunus persicae (L.) Batsch, roots is common by several plant pathogen species and by larvae of the peachtree borer, Synanthedon exitiosa Say (Lepidoptera: Sesiidae). External feeding injury to peach roots was observed that was not consistent with S. exitiosa injury but was suspected to be caused by the larvae of root-feeding weevil species (Coleoptera: Curculionidae). Thus, we used conical emergence traps for 3 yr to sample in unsprayed peach orchards (within the dripline of trees and at missing tree sites) to monitor for root-feeding weevils. Fuller rose beetle, Naupactus cervinus (Boheman), whitefringed beetles, Naupactus spp., and the twobanded Japanese weevil, Callirhopalus bifasciatus (Roelofs), (Coleoptera: Curculionidae) were captured at significantly higher numbers within the dripline of the tree than at missing tree sites. Adult N. cervinus emerged from soil year around; whereas, the other 2 species had seasonal emergence. In commercial peach orchards comprised of cultivars with early, mid, and late-season fruit ripening dates, N. cervinus was more abundant than other species. The later a cultivar ripens, the higher the number of insecticide applications it receives; however, we did not detect a difference in N. cervinus emergence between the cultivars. In another sprayed orchard, N. cervinus was again more common than other curculionid species captured. Damage ratings (0 - 5; none to heavy, respectively) on roots revealed a mean rating of 2.79 +/- 0.12. Year-long emergence of N. cervinus is likely why it persisted in sprayed orchards. Modification of existing pest management programs will be needed to manage N. cervinus attacking peach roots.

AB Management of the western tarnished plant bug, Lygus hesperus Knight, in cotton usually relies on population estimates obtained using the sweepnet. Recent studies indicated adult L. hesperus gender and physiological age influence feeding behavior, within-plant distribution, and injury to cotton. Whether these differences in behavior also influence capture by the sweepnet is not known. We evaluated the sweepnet for sampling L. hesperus adults of known gender and age class in Pima and Acala Upland cotton. Adults of 4 classes (females, prereproductive or reproductive; males, prereproductive or reproductive) marked with fingernail polish to prevent flight were released into assigned sample rows. Captures of marked adults declined seasonally in all experiments. In Pima cotton, the sweepnet was least effective for sampling prereproductive female L. hesperus, and most effective for collecting reproductive males. Captures of reproductive females and prereproductive males were intermediate. We suggest the influence of adult gender and age class on sweepnet captures in Pima cotton corresponds to a propensity for prereproductive adults to reside within plant terminals substantially shielded by foliage. Similar differences in Upland cotton were not observed, probably because the comparatively open structure of the Upland terminal minimized the effects of gender and age class on collection efficiency. Finally, dissection of native L. hesperus indicated. an age structure dominated by reproductive maturity. Therefore, future mark-release-recapture studies of factors influencing sweepnet sampling for L. hesperus adults in cotton may maximize relevance by focusing on reproductively mature adults.

AB A new method to refine existing dietary supplements for improving production of the yellow mealworm, Tenebrio molitor L. (Coleoptera: Tenebrionidae), was tested. Self-selected ratios of 6 dietary ingredients by T molitor larvae were used to produce a dietary supplement. This supplement was compared with existing supplement formulations mixed with wheat bran at 1:4 ratio and a control consisting of wheat bran alone for food utilization efficiency, larval growth, development time, immature survival, and fecundity. Ingredients of dietary supplements included dry potato as a source of carbohydrate; dry egg white and soy protein as a source of protein and; peanut, canola, and salmon oil as a source of lipid. A supplement consisting of dry potato alone significantly improved food utilization, growth, development time, survival, and fecundity compared with the wheat bran-only control group. The addition of protein to the supplement significantly shortened development time and improved food conversion efficiency and fecundity compared with the supplement with potato alone. The addition of lipid did not provide any significant improvements. The supplement derived from self-selected ratios of the basic ingredients provided a significant increase in fecundity compared with previously developed supplements and the control. Self-selected ratios of the basic ingredients by T molitor larvae had an effect on the adult stage that resulted in significantly higher progeny production.

AB In the present study, the feasibility and advantages of a flow-injection mass spectrometric (FIMS) fingerprinting method combined with chemometrics for quick differentiation and quality assessment of di- and tetraploid leaf and whole-plant Gynostemma pentaphyllum (Thunb.) Makino (Jiaogulan in Chinese) were investigated for the first time. The rapid FIMS fingerprinting method was applied to generate spectrometric fingerprints of four different types of G. pentaphyllum samples. Chemometrics, including principal component analysis (PCA) and partial least square discriminative analysis (PLS-DA), were used to analyze the fingerprints. The results showed that each sample could be effectively differentiated and classified in 2 min. Furthermore, eleven characteristic ions that played the most important roles for differentiating the four groups of G. pentaphyllum samples were screened out by loadings plot from PLS-DA.

AB The colonization of food processing plants by stored-product pests and their distribution within a facility depend, in part, on their dispersal ability. In this case study, we relied on self-mark recapture to evaluate the ability of Tribolium castaneum, the red flour beetle, to move among floors within a flour mill and the effects of a heat treatment on insect activity. Marking stations with pheromone and fluorescent powder were placed on each of five floors in the mill, and two techniques were used to recover marked individuals (trapping and direct collection of individuals from the floor). Considering both recovery techniques, T. castaneum was able to move among floors, but the majority of individuals remained on the same floor where they were marked (86%). Most individuals captured on a different floor were captured on a floor below the one they were marked (70%) and adjacent to it (87%). There was a spike in the number of beetles captured during heat treatment, but not an increase in movement of marked beetles between floors. These results suggest that the rate of heating was sufficient to prevent beetles time to move to cooler floors to escape heat. T. castaneum movement among floors needs to be taken into account when identifying sources of infestation and targeting pest management. Published by Elsevier Ltd.

AB Bovine brucellosis, caused by the bacterium Brucella abortus, is endemic in bison (Bison bison) and elk (Germs elaphus nelsoni) populations in the area of Yellowstone. National Park, USA. Two strategies have been proposed to reduce the risk of transmission, of disease in bison remote vaccination with the vaccine RB51, and the use of immunocontraception of bison to decrease shedding of organisms from infected females. The frequent occurrence of venereal transmission in bison would complicate either of these strategies, requiring vaccination of males as well as females, and rendering immunocontraception less effective in reducing transmission of B. abortus. To address the question of venereal transmission, we inoculated each of 18 bison cows with 4.5 X 10(8) colony-forming units of B. abortus strain 19, as a surrogate of field strain, by three routes: intraconjunctival (IC), intravaginal (VI), and intracervical/intrauterine (AI). Bison semen was mixed with strain 19 inoculum for the latter route. Bison were monitored by serology and culture for 12 wk, at which time they were euthanized and specimens collected for culture. All IC-inoculated animals seroconverted on multiple tests and one was culture positive at 12 wk postexposure. Seven of eight VI bison developed suspect or positive serologic tests and four were positive at one or more time points. Weak transient serologic responses (suspect) were seen in four of five AI bison. Results showed that IC inoculation with strain 19 was a suitable surrogate for field strain to demonstrate exposure to the B. abortus. The seroconversion of four of eight VI bison indicated exposure of the immune system to the agent and the need for further studies on venereal transmission in bison.

DE Colorado; Leptospira interrogans; leptospirosis; squirrel; wildlife
ID UNITED-STATES
AB Leptospirosis is a zoonotic disease caused by the bacterium Leptospira interrogans. The organism is typically maintained within a geographic region by colonizing renal tubules of carrier animals and shed into the environment in urine. We assessed whether L. interrogans was present in fox squirrels (Sciurus niger) in Larimer County, Colorado, USA, and whether it is associated with disease. Twenty-two squirrels were trapped from 29 November 2011 to 15 December 2011 for use in an unrelated study. The squirrels were individually housed for 33-65 days and euthanized; no clinical disease was observed. On gross examination, significant renal lesions were observed in 6 of 22 animals (27%). Histologically, affected animals had severe neutrophilic tubulitis with interstitial nephritis Immunohistochemistry was conducted on the kidneys of all animals and 10 of 22 (45%) were positive for L. interrogans, with varying severity of infection. The same 10 squirrels were serologically positive for antibodies specific to L. interrogans. These results suggest that L. interrogans is present in fox squirrels in Larimer County, Colorado, USA, and may be associated with varying degrees of renal disease. Further investigation into the role of wildlife in the ecology of leptospirosis within the region is warranted.

ID CERVUS-ELAPHUS NELSONI; WHITE-TAILED DEER; PRPCWD; PATTERNS
AB Chronic wasting disease (CWD) adversely affects both wild and captive cervid populations. A vaccine to prevent CWD would be a highly desirable tool to aid in disease management. To this end, we tested in mule deer a combination of CWD vaccines consisting of cervid prion peptide sequences 168-VDQYNNQNTFVHDC-182 and 145-NDYEDRYYRENMYRYPNQ-164 that had previously been shown to delay onset of clinical disease and increase survival in a mouse-adapted scrapie model. Thirteen captive mule deer (Odocoileus hemionus) were divided into vaccine (n=7) and control groups (n=6), and given prime and boost vaccinations intramuscularly 5 wk apart. Eight weeks postprime (3 wk postboost), all animals were challenged via natural exposure to an environment contaminated with infective CWD prions. Deer were monitored intermittently for prion infection by rectal and tonsil biopsies beginning 275 days postchallenge. All vaccinates responded to both peptide conjugates present in the combination vaccine as measured by enzyme-linked immunosorbent assay. However, all deer eventually became infected regardless of vaccine status.

AB Although pseudorabies virus can affect a wide range of mammalian and avian hosts, swine are the only natural hosts of the virus. The US commercial swine industry obtained pseudorabies-free status in 2004, which was important because of the economic value of domestic swine production; however, feral swine remain competent hosts and represent a constant threat for reintroducing the virus into the commercial industry. To better assess feral swine infection status, we collected 8,498 serum samples from feral swine across the United States between 1 October 2009 and 30 September 2012. Of these, 18% were antibody positive in 25 of 35 states where samples were collected, indicating that transmission risk is widespread.

ID INFECTION
AB To determine if bison (Bison bison) bulls from Yellowstone National Park (YNP), Montana, USA, shed an infective dose of Brucella abortus in semen, 50 YNP bulls were captured on public lands in Montana during the winter and early spring (April-May) of 2010 and 2011. The bulls were immobilized, and blood and semen samples were collected for serology and Brucella culture. Thirty-five bulls (70%) were antibody-positive, and B. abortus was cultured from semen in three (9%) of the 35 antibody-positive or suspect bulls, though not at concentrations considered an infective dose. Eight bulls (six antibody-positive, two negative) had palpable lesions of the testes, epididymides, or seminal vesicles consistent with B. abortus infection. Breeding soundness exams and semen analysis suggested that antibody-positive bulls were more likely to have nonviable ejaculate (8/35; 23%) than bulls without detectable antibody (2/15; 13%).

AB Crop yields at summit positions of rolling landscapes often are lower than backslope yields. The differences in plant response may be the result of many different factors. We examined corn (Zea mays L.) plant productivity, gene expression, soil water, and nutrient availability in two landscape positions located in historically high (backslope) and moderate (summit and shoulder) yielding zones to gain insight into plant response differences. Growth characteristics, gene expression, and soil parameters (water and N and P content) were determined at the V12 growth stage of corn. At tassel, plant biomass, N content, C-13 isotope discrimination (Delta), and soil water was measured. Soil water was 35% lower in the summit and shoulder compared with the lower backslope plots. Plants at the summit had 16% less leaf area, biomass, and N and P uptake at V12 and 30% less biomass at tassel compared with plants from the lower backslope. Transcriptome analysis at V12 indicated that summit and shoulder-grown plants had 496 downregulated and 341 upregulated genes compared with backslope-grown plants. Gene set and subnetwork enrichment analyses indicated alterations in growth and circadian response and lowered nutrient uptake, wound recovery, pest resistance, and photosynthetic capacity in summit and shoulder-grown plants. Reducing plant populations, to lessen demands on available soil water, and applying pesticides, to limit biotic stress, may ameliorate negative water stress responses.

ID ARABIDOPSIS-THALIANA; PACKAGE
AB Soybean [Glycine max (L.) Merr.] seeds contain high levels of mineral nutrients essential for human and animal nutrition. High throughput elemental profiling (ionomics) has identified mutants in model plant species grown in controlled environments. Here, we describe a method for identifying potential soybean ionomics mutants grown in a field setting and apply it to 975 N-nitroso-N-methylurea (NMU) mutagenized lines. After performing a spatial correction, we identified mutants using either visual scoring of standard score (z-score) plots or computational ranking of putative mutants followed by visual confirmation. Although there was a large degree of overlap between the methods, each method identified unique lines. The visual scoring approach identified 22 out of 427 (5%) potential mutants, 70% (16 out of 22) of which were confirmed when seeds from the same parent plant were regrown in the field. We also performed simulations to determine an optimal strategy for screening large populations. All data from the screen is available at the Ionomics Hub File Transfer Page (http://www.ionomicshub.org/home/PiiMS/dataexchange).

AB Sensor networks are revolutionizing environmental monitoring by producing massive quantities of data that are being made publically available in near real time. These data streams pose a challenge for ecologists because traditional approaches to quality assurance and quality control are no longer practical when confronted with the size of these data sets and the demands of real-time processing. Automated methods for rapidly identifying and (ideally) correcting problematic data are essential. However, advances in sensor hardware have outpaced those in software, creating a need for tools to implement automated quality assurance and quality control procedures, produce graphical and statistical summaries for review, and track the provenance of the data. Use of automated tools would enhance data integrity and reliability and would reduce delays in releasing data products. Development of community-wide standards for quality assurance and quality control would instill confidence in sensor data and would improve interoperability across environmental sensor networks.

AB Fraxinus nigra Marsh. (black ash) is a native North American hardwood tree species that is ecologically important and has ethnobotanical significance to American Indian communities of the eastern United States. Black ash has immature embryos at seed set, combined with complex stratification requirements, making natural regeneration difficult. This, combined with the threat and devastation being caused by the emerald ash borer, makes an in vitro adventitious shoot regeneration and rooting protocol imperative for mass propagation, conservation, and genetic improvement of this species. Hypocotyls were cultured for 4 weeks on a modified Murashige and Skoog (MS) medium containing 13.3 mu M 6-benzylaminopurine (BA) and 4.5 mu M thidiazuron for adventitious shoot induction. Shoots continued to regenerate when explants were then cultured on MS medium supplemented with Gamborg B5 vitamins plus 0.2 g.L-1 glycine (B5G), 6.7 mu M BA, 1 mu M indole-3-butryic acid (IBA), and 0.29 mu M gibberellic acid (GA(3)) for 4 weeks, followed by transfer to MSB5G medium with 13.3 mu M BA, 1 mu M IBA, and 0.29 mu M GA(3) for shoot elongation. Once elongated, the microshoots were continuously micropropagated through nodal sectioning, and cultured on MSB5G medium supplemented with 13.3 mu M BA, 1 mu M IBA, 0.29 mu M GA(3), and 0.2 g.L-1 casein hydrolysate. Rooting of elongated microshoots was successful using woody plant medium supplemented with 4.9 mu M IBA and 5.7 mu M indole-3-acetic acid with a 10-day initial dark culture for root induction followed by culture under a 16-h photoperiod. Rooted plantlets were successfully acclimatized to the greenhouse with 100% survival.

TI Effects of seasonal variations of sugarcane stalk and extraneous matter

Part I
SO INTERNATIONAL SUGAR JOURNAL

variations; starch; sugarcane
ID TRASH AFFECTS PRODUCTION; GREEN CANE BILLETS; REGISTRATION; INTERMEDIATE
AB There are presently worldwide trends to manufacture high quality raw sugars for supply to refineries, e.g., very high pol and very low color (VHPNLC) raw sugars, and to use sugarcane extraneous matter (trash or leaves and tops) as a source of biomass. Raw sugar quality is dependent on the quality of the incoming cane supply across the processing season which, in turn, is greatly affected by the quantities and types of non-stalk tissues present. Strategies to improve the quality of raw sugar will require attention to seasonal cane quality factors as well as process manipulations. This study was undertaken to ascertain seasonal cane supply variations in juice quality parameters that affect raw sugar manufacture across the Louisiana (LA) 3-month processing season (late Sept to Dec) in 2009 and 2010. Across both seasons, maximum daily air temperature decreased with little difference in the average values (ay. 23.3 degrees C), but there was consistently higher daily rainfall in 2009 (ay. 13.7 mm) than 2010 (ay. 1.8 mm). Juice was extracted from separated stalk (S), growing point region (GPR or top), green leaf (GL) and brown leaf (BL) tissues of three commercial sugarcane varieties: HoCP 96-540, L 99-226, and L 99-233, at least five times between Sept and Dec. For all three varieties across harvest dates, the average total trash value (GPR + GL + BL) was 20.6% on wet weight. The most popular LA variety HoCP 96-540, still had relatively high levels of total trash until late Nov. There was a significant (P<.05) harvest date by varietal interaction for theoretical recovery of sugar in stalk. The maturity characteristic of the variety played a critical role in seasonal variation of quality parameters, especially starch. Compared to early and mid-maturing varieties, L99-226 and HoCP 96-540, respectively, which mostly delivered starch to the factories in green leaves, the later maturing variety L99-233 delivered starch mostly in the stalk after mid Oct. Thus blowing off extraneous matter in the field or at the factory for L99-233 would help little to control starch levels after mid Oct The greatest (P<.05) variation in harvest date effect on starch concentration was in the stalk, and there was also a very strong varietal effect on starch. In contrast, the least varietal variation in juice quality parameters occurred in the GPR. Fiber did not vary considerably across the season for all varieties. Overall, for all parameters studied the type of tissue had the strongest effect, followed by variety, then date of harvest; the varietal effect was greatest in the stalk than other tissues. This suggests that breeding programs could include quality parameters as selection criteria.

AB We present an updated catalog of North American Eucoilinae, bearing little resemblance to previous regional catalogs, which have been lagging behind in the recent systematic work in the group. The current catalog comprises 34 genera, arranged in six tribes. Of these genera, 9 are represented wholly by unidentified or undescribed species in the region, while the other 25 include 108 species recorded from the region. In comparison with previous catalogs, 24 genera and 41 species are added, and 34 species-level names are recombined, while 7 genera, five subgenera and 11 species are removed from the list of North American taxa. A modern, phylogenetically stable and type-based classification is implemented, as well as a tribal classification. In terms of nomenclatural acts, 25 new combinations are made (one is a reinstatement of an old combination); four new genus-levels synonymies are made (Tetramerocera Ashmead junior synonym of Ganaspis Forster, Bewelda Quinlan and Aporeucoela Kieffer junior synonyms of Hexacola Forster, Pentaplastidia Weld junior synonym of Trybliographa Forster); eight new species-level synonymies are made; two species names are removed from synonymy; one new replacement name given (Hexacola pennsylvanicus for Hexacola subaperta Kieffer 1907 nec (Kieffer 1901a)).

AB Cattle weight gain responses to seasonal weather variability are difficult to predict for rangelands because few long-term (>20 yr) studies have been conducted. However, an increased understanding of temperature and precipitation influences on cattle weight gains is needed to optimize stocking rates and reduce enterprise risk associated with climatic variability. Yearling steer weight gain data collected at the USDA-ARS High Plains Grasslands Research Station at light, moderate, and heavy stocking rates for 30 years (1982-2011) were used to examine the effects of spring (April-June) and summer (July-September) temperature and precipitation, as well as prior-growing-season (prior April-September) and fall/winter (October-March) precipitation, on beef production (kg . ha(-1)). At heavier stocking rates, steer production was more sensitive to seasonal weather variations. A novel finding was that temperature (relatively cool springs and warm summers) played a large predictive role on beef production. At heavier stocking rates, beef production was highest during years with cool, wet springs and warm, wet summers, corresponding to optimum growth conditions for this mixed C-3-C-4 plant community. The novelty and utility of these findings may increase the efficacy of stocking rate decision support tools. The parsimonious model structure presented here includes three-month seasonal clusters that are forecasted and freely available from the US National Oceanic and Atmospheric Administration up to a year in advance. These seasonal weather forecasts can provide ranchers with an increased predictive capacity to adjust stocking rates (in advance of the grazing season) according to predicted seasonal weather conditions, thereby reducing enterprise risk.

AB Monotypic stands of crested wheatgrass (Agropyron cristatum [L] Gaertm. and Agropyron desertorum [Fisch.] Schult.), an introduced grass, occupy vast expanses of the sagebrush steppe. Efforts to improve habitat for sagebrush-associated wildlife by establishing a diverse community of native vegetation in crested wheatgrass stands have largely failed. Instead of concentrating on. a diversity of species, we evaluated the potential to restore the foundation species, Wyoming big sagebrush (Artemisia tridentata spp. wyomingensis [Beetle & A. Young] S. L. Welsh), to these communities. We investigated the establishment of Wyoming big sagebrush into six crested wheatgrass stands (sites) by broadcast seeding and planting seedling sagebrush across varying levels of crested wheatgrass control with glyphosate. Planted sagebrush seedlings survived at high rates (similar to 70% planted sagebrush survival 3 yr postplanting), even without crested wheatgrass control. However, most attempts to establish sagebrush by broadcast seeding failed. Only at high levels of crested wheatgrass control did a few sagebrush plants establish from broadcasted seed. Sagebrush density and cover were greater with planting seedlings than broadcast seeding. Sagebrush cover, height, and canopy area were greater at higher levels of crested wheatgrass control. High levels of crested wheatgrass control also created an opportunity for exotic annuals to increase. Crested wheatgrass rapidly recovered after glyphosate control treatments, which suggests multiple treatments may be needed to effectively control crested wheatgrass. Our results suggest that planting sagebrush seedlings can structurally diversify monotypic crested wheatgrass stands to provide habitat for sagebrush-associated wildlife. Though this is not the full diversity of native functional groups representative of the sagebrush steppe, it is a substantial improvement over other efforts that have largely failed to alter these plant communities. We also hypothesize that planting sagebrush seedlings in patches or strips may provide a relatively inexpensive method to facilitate sagebrush recovery across vast landscapes where sagebrush has been lost.

AB When hydrogen peroxide is mixed with caustic soda, an auto-accelerating reaction can lead to generation of significant amounts of heat and oxygen. On the basis of experiments using typical pulp mill process concentration and temperatures, a relatively simple kinetic model has been developed. Evaluation of these model results reveals that hydrogen peroxide-caustic soda systems are extremely sensitive to hydrogen peroxide: caustic soda ratio, transition metal contamination, and temperature. Small changes in initial conditions can result in a closed system becoming explosive. Analysis of model results was used to develop guidelines for safer application of hydrogen peroxide in a mill setting.

AB Empirically assessing sanitary and phytosanitary regulations has proven difficult because most data sources indicate whether a regulation exists but provide no information on the type or importance of the respective measure. In this article, we construct a novel database of U.S. phytosanitary measures and match these to 47 fresh fruit and vegetable product imports from 89 exporting countries over the period 1996-2008. A product-line gravity equation that accounts for zero trade flows is developed to investigate the trade impact of different pest-mitigation measures. While the results suggest that phytosanitary treatments generally reduce trade, the actual restrictiveness of these measures diminishes dramatically as exporters accumulate experience, and it vanishes when exporters reach a certain threshold. The results have important policy implications considering the number of empirical studies that find a negative impact of non-tariff measures on trade.

AB A bench scale fluidized bed system was modified to recycle and utilize the gaseous products of biomass fast pyrolysis as fluidization gas and to create a reactive gas atmosphere to replace, in part or in full, the added nitrogen gas. The effect of the presence of the reducing atmosphere on the pyrolysis oils produced was studied for three different biomass feedstocks, white oak, switchgrass, and pennycress presscake, and compared with those produced under an inert N-2 atmosphere as the control. The reductive atmosphere, consisting primarily of CO, CO2, H-2, and light hydrocarbons, had a significant deoxygenation effect on the pyrolysis oil produced from oak and switchgrass. The effect was significantly smaller for the pyrolysis of pennycress presscake, which inherently produces a lower oxygen product. When oak and switchgrass were used as feedstocks, pyrolysis oils with molar C/O ratios of 9.1 and 8.5 were achieved, respectively, which is increased from about 2.1 for the control experiments for each feedstock. The pyrolysis oils produced under the reducing atmosphere were richer in aromatic hydrocarbons and nonmethoxylated phenolics and had lesser concentrations of levoglucosan and acids than were the pyrolysis oils in the control experiments. These pyrolysis oils had lower total acid numbers (TAN) and higher energy content than those produced in the control experiments. These results compare favorably to zeolite catalyzed fast pyrolysis but without the added catalyst cost and concern for catalyst deactivation or need for regeneration.

AB The stabilization and upgrading of pyrolysis oil requires the neutralization of the acidic components of the oil. The conversion of small organic acids, particularly acetic acid, to ketones is one approach to addressing the instability of the oils caused by low pH. In the ketonization reaction, acetic acid is converted to acetone, water, and CO2. Here, a 16 vol % acetic acid solution is converted to acetone in a flow reactor over the mixed oxide Fe0.2Ce0.2Al0.6Ox in the presence of several other components meant to represent pyrolysis oil. These components include hydroxyacetone, furfural, phenol, cresol, guaiacol, and eugenol. Hydroxyacetone also undergoes ketonization, forming acetone, 2-butanone, 3-pentanone, and 2- and 3-hexanone. A mechanism for the ketonization of hydroxyacetone through propanal is proposed and supported by incorporation of isotopically labeled water. Inhibition of the reaction occurs to a significant degree by the addition of furfural, guaiacol, and eugenol.

AB From egg to adult, all life history stages of house flies associate with septic environments teeming with bacteria. House fly lysozyme was first identified in the larval midgut, where it is used for digestion of microbe-rich meals because of its broad-spectrum activity against gram-positive and gram-negative bacteria as well as fungi. This study aimed to determine the temporal expression of lysozyme in the life history of house flies ( from egg through adults) on both the mRNA and protein level, and to determine the tissue-specific expression of lysozyme in adult flies induced by feeding Staphylococcus aureus. From 30-min postoviposition through adulthood, all life history stages of the house fly express lysozyme on the mRNA level. In adult flies, lysozyme is expressed both locally in the alimentary canal and systemically in the fat body. Interestingly, we found that during the normal life history of flies, lysozyme protein was only detected in larval stages and older adults, likely because of ingestion of immune-stimulating levels of bacteria, not experienced during egg, pupa, and teneral adult stages. Constitutive expression on the mRNA level implies that this effector is a primary defense molecule in all stages of the house fly life history, and that a mechanism for posttranscriptional control of mature lysozyme enzyme expression may be present. Lysozyme active enzyme primarily serves both a digestive and defensive function in larval and adult flies, and may be a key player in the ability of Musca domestica L. to thrive in microbe-rich environments.

AB Malaria infection is a serious public health problem throughout Liberia, but vector surveillance is limited or nonexistent in remote regions of the country. To better understand the spatial and temporal distribution of malaria vectors in Liberia and to support vector and malaria activities of the Liberian Ministry of Health, a study was conducted to determine the efficacy of light traps baited with a synthetic lure and CO 2 for capturing Anopheles gambiae sensu lato (Giles). Traps with a ultraviolet, light-emitting diode, and incandescent lights baited with a synthetic skin lure and CO 2 combinations were evaluated at four field sites in three counties of Liberia for five consecutive nights every 8 wk during 2011. In total, 4,788 mosquitoes representing 56 species from nine genera were collected throughout the 30-wk study; An. gambiae s. l. comprised 32% and of the 148 An. gambiae s. s. collected, 85% were of the S form. A greater percentage of An. gambiae s. l. were collected in ultraviolet traps baited with a synthetic lure and CO2 compared with any other trap configuration. The influence of trap configuration on conclusions from surveillance efforts, specifically with regards to An. gambiae is discussed.

AB The stable fly, Stomoxys calcitrans (L.), is a serious ectoparasite affecting animal production and health of both animals and humans. Stable fly control relies largely on chemical insecticides; however, the development of insecticide resistance as well as environmental considerations requires continued discovery research to develop novel control technologies. MicroRNAs (miRNAs) are a class of short noncoding RNAs that have been shown to be important regulators of gene expression across a wide variety of organisms, and may provide an innovative approach with regard to development of safer more targeted control technologies. The current study reports discovery and initial comparative analysis of 88 presumptive miRNA sequences from the stable fly, obtained using high-throughput sequencing of small RNAs. The majority of stable fly miRNAs were 22-23 nt in length. Many miRNAs were arthropod specific, and several mature miRNA sequences showed greater sequence identity to miRNAs from other blood-feeding dipterans such as mosquitoes rather than to Drosophilids. This initial step in characterizing the stable fly microRNAome provides a basis for further analyses of life stage-specific and tissue-specific expression to elucidate their functional roles in stable fly biology.

AB Clogging of soil pipes due to excessive internal erosion has been hypothesized to cause extreme erosion events such as landslides, debris flows, and gullies, but confirmation of this phenomenon has been lacking. Laboratory and field measurements have failed to measure pore-water pressures within pipes and models of pipe flow have not addressed internal erosion or pipe clogging. The objective of this study was to model laboratory experiments of pipe flow in which clogging was observed in order to understand the clogging process. Richards' equation was used to model pipe flow, with the soil pipe represented as a highly conductive, low-retention porous medium. The modeling used two contrasting boundary conditions, constant flux (CF) and constant head (CH), to quantify pressure buildups due to pipe clogging and differences in simulated pressures between the two imposed boundary conditions. Unique to these simulations was inclusion of pipe enlargement with time due to internal erosion, representation of partially full flow conditions, and inclusion of pipe clogging. Both CF and CH boundary conditions confirmed the concept of pressure buildup as a result of pipe clogging. Pressure jumps of around 54 m for CF and 18 cm for CH occurred in <0.1 s, while soil water pressures 4 cm radially outward from the pipe had not responded. These findings demonstrate the need to measure pressures within soil pipes due to hydraulic nonequilibrium between the pipe and soil matrix. Pore water pressures within the pipe below the clog rapidly (<0.25 s) drained to unsaturated conditions, indicating the ability of soil pipes to drain hillslopes and rapidly recover when clogs are flushed from the soil pipe. These dynamic processes need to be incorporated into stability models to properly model hillslope processes.

AB Phenolic compounds, called tannins, can be retained by soil and affect soluble N but have been studied in only a few soil types. Surface samples (0-10 cm), collected from the United States and Canada, were treated with water (Control) or solutions containing procyanidin, catechin, beta-1,2,3,4,6-pentagalloyl-O-D-glucose (PGG), tannic acid, gallic acid, or methyl gallate. Soluble C and N in treatment supernatants and after incubation (16 h, 80 degrees C) were measured to determine retention of treatment C and effects on soluble N and cation exchange capacity (CEC). Retention varied significantly with treatment (T) and soil order (S) and was greatest for PGG > tannic acid > procyanidin > catechin > methyl gallate > gallic acid and in Alfisols, Aridisols and Mollisols compared Ultisols. However, differences among soil orders were observed only for strongly retained compounds (T x S, P < 0.001). Extraction of soluble N was decreased by gallic acid and tannins, especially PGG, but unaffected by methyl gallate or catechin. All treatments decreased soluble N from Aridisols while Entisols were less affected by tannins (T x S, P < 0.01). Soil CEC was significantly increased by tannins but unaffected by other compounds. However, CEC increased more in Aridisols than in Mollisols or Ultisols and treatment effects were small and unvarying in Ultisols (T x S, P < 0.001). Changes to both soluble N and CEC were linearly related with retention of treatment C. Tannins produced effects associated with improved soil quality on a broad range of soils and may have a role in land management.

AB Irrigation and tillage systems may affect surface residue and soil C and N fractions by influencing crop biomass yield, residue placement, and movement of water soluble C and N in the soil. We studied the effects of irrigation (mid-elevation spray application [MESA] and low energy precision application [LEPA]) and tillage (conventional [CT] and strip-tillage [ST]) systems on crop biomass (stems and leaves) yield, surface residue, and soil C and N fractions at the 0- to 20-cm depth from 2004 to 2007 in a Savage clay loam (fine, smectitic, frigid Vertic Argiustolls) in Sidney, MT. Soil C and N fractions were soil organic carbon (SOC) and total nitrogen (STN), particulate organic carbon and nitrogen (POC and PON), microbial biomass carbon and nitrogen (MBC and MBN), potential carbon and nitrogen mineralization (PCM and PNM), NH4-N, and NO3-N. While crop biomass across treatments increased from 2004 to 2007, surface residue was greater with ST than with CT from 2005 to 2007. The NH4-N and NO3-N contents at 5 to 10 and 10 to 20 cm in 2005 and STN at 0 to 5 cm in 2007 were greater with ST than with CT, but SOC at 5 to 10 and 10 to 20 cm, POC and MBN at 5 to 10 cm, and PNM at 0 to 5 cm in 2007 were greater with CT than with ST. The MBC at 0 to 5 cm and MBN at 10 to 20 cm were greater in LEPA than in MESA. The PCM at 10 to 20 cm was greater with CT than with ST in LEPA. While ST increased surface soil residue and N storage, residue incorporation to a greater depth in CT increased soil C storage, microbial activity, and N mineralization. Slow rate of water application near the soil surface increased microbial biomass in LEPA.

AB A study was initiated in soils of two southern Illinois loess-derived landscapes to investigate the distribution of selected trace and major elements. The objective of the research was to link the distribution of elements in different landscape positions to important soil and landscape processes. Seventeen pedons (representing different geomorphic hillslope positions) at the Morgan Pond (MP) and Bean Ridge (BR) sites were sampled by horizon. Data were evaluated by grouping selected horizons (A, Bt) by site (MP and BR) as well as by geomorphic hillslope position. Results show that relative concentrations of total As, Cr, Cu, V, Ni, Pb, Se, and Zn between these two sites were impacted by differences in inherent particle size distribution of the parent material. These elements were also greater in Bt versus A horizons within each site, suggesting that select elements were redistributed by clay illuviation processes. Barium, Ca, Cd, Hg, and Pb were all significantly elevated in A relative to Bt horizons at the BR site and were strongly correlated with total C, suggesting biocycling and trace element bioaccumulation were important in landscape positions of this site. The MP site lacked this same concentration of elements in surface horizons, demonstrating the effect of accelerated erosion due to more intensive cropping history. When grouping data by landscape position, elemental distribution and Bt/A clay ratios showed that landscape stability was greatest in summit positions relative to other positions (summit > shoulder > backslope positions), confirming that relative amount of soil erosion was also related to landscape position among these sites.

TI Dynamic Soil Properties across a Suburban Landscape
SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL

DT Article
ID BULK-DENSITY; URBAN SOILS; CARBON
AB Soil properties in urban settings are impacted by human activities. This study investigated human influence on dynamic soil properties including bulk density (BD), organic C (OC), pH, and inorganic C (IC) in the suburban environment of Ankeny, IA. Nine periods of urban development were delineated, and 10 homes from each period were randomly selected. Soils were sampled from front yards of these homes. All soils had a loamy texture. Mean BD values were significantly higher (1.70 g cm(-3)) in newer developments than older sites (1.23 g cm(-3)). Bulk density increased significantly with depth. This could be the effect of increased compaction associated with newer and heavier equipment in the case of newer developments and improved aggregation and structural development in soils in older areas. Soils from the 2003 to 2005 period had significantly lower levels of OC (0.49 g kg(-1)) than those from the pre(-1)939 period (4.49 g kg(-1)). Mean OC decreased with depth. The pH ranged from 5.4 to 8.5, with a mean of 7.7, and pH increased with time of development and with depth. Disturbance at newer sites could have exposed calcareous till. Long-term use of acid fertilizers could have decreased surface pH. The amount of IC ranged from 0.11 g kg(-1) in the older development to 8.41 g kg(-1) in the newest development. The IC increased with depth. These results could indicate that time has impacted the loss of IC through leaching and acid-forming processes. We conclude that current intensive site preparation techniques significantly affect dynamic soil properties; however, this impact is reduced as the time since the initial disturbance increases.

TI Effect of No-Till and Extended Rotation on Nutrient Losses in Surface

AB No-till crop production can reduce soil erosion compared to conventional tillage, but there is concern that lack of fertilizer incorporation will increase loss of dissolved nutrients in surface runoff. Therefore, we compared nutrient and sediment loss from two no-till and two chisel-till small (0.45-0.79 ha) watersheds managed in a 2-yr corn (Zea mays L.)/soybean [ Glycine max (L.) Merr]-rye (Secale cereale L.) cover crop rotation for 16 crop years. We also investigated the effect of replacing some of the mineral N with manure and red clover by monitoring runoff from three watersheds in a 3-yr corn/soybean/wheat-red clover (Triticum aestivum L.-Trifolium pratense L.) extended rotation. The reduced-input watersheds were disked in corn and soybean years. For all tillage treatments, NO3-N losses were greatest with corn and averaged from 3.7 (no-till) to 5.5 kg ha(-1) yr(-1) (chisel) for all crop years. Average dissolved P losses were 0.21 kg ha(-1) yr(-1) (chisel), 0.32 kg ha(-1) yr(-1) (no-till), and 0.84 kg ha(-1) yr(-1) (reduced-input). Total P losses were least from no-till (0.79 kg ha(-1) yr(-1)), intermediate for chisel (0.84 kg ha(-1) yr(-1)), and greatest for reduced-input watersheds (1.68 kg ha(-1) yr(-1)). Soil loss was least from no-till (807 kg ha(-1) yr(-1)), intermediate from chisel (1073 kg ha(-1) yr(-1)), and greatest from reduced-input watersheds (1177 kg ha(-1) yr(-1)). Thus, no-till had only slightly greater dissolved P losses compared to chisel, but had smaller soil, NO3-N, and total P losses. The greater dissolved and total P losses, as well as greater soil loss, compared to chisel and no-till watersheds, indicated that there was no surface water quality benefit to the reduced-input extended rotation.

AB Cellulosic biofuel production may generate new markets and revenue for farmers. However, residue removal may cause environmental problems such as soil erosion and soil organic matter (SOM) loss. The objective of this study was to determine the amounts of residue necessary for SOM maintenance under different tillage and residue removal scenarios for corn-soybean [ Zea mays L.-Glycine max (L.) Merr.] and continuous corn rotations for a site in west-central Minnesota. We employed a process-based model (CQESTR) to evaluate management practices and quantify SOM changes over time. Results showed that conventional tillage resulted in SOM loss regardless of the amount of residue returned. Under no-till, residue amount was important in determining SOM accumulation or depletion. For the upper 30 cm of soil, average annual rates of 3.65 and 2.25 Mg crop residue ha(-1) yr(-1) were sufficient to maintain SOM for corn-soybean and continuous corn rotations, respectively. Soil OM in soil layers below 30 cm was predicted to decrease in all scenarios as a result of low root inputs. When considered over the upper 60 cm (maximum soil depth sampled), only continuous corn with no-till was sufficient to maintain SOM. Results from this work are important because they show that, for these management scenarios, no-till management is necessary for SOM maintenance and that determining whether SOM is accumulating or declining depends on the soil depth considered. At current yields observed in this study area, only continuous corn with no-till may generate enough residue to maintain or increase SOM.

AB Hybridization between apple maggot, Rhagoletis pomonella (Walsh), and Rhagoletis zephyria Snow (Diptera: Tephritidae) occurs in Washington State, complicating fly identifications. Here, experimentally generated F 1 hybrids of R. pomonella and R. zephyria were classified using morphometric methods. Five of nine mean body size measurements of hybrids from crossing female R. pomonella x male R. zephyria were intermediate between those of nonhybrids. Aculeus lengths of hybrid females were intermediate or were more similar to those of R. pomonella than R. zephyria. Based on six or seven body size measures, 25.0% of female and 44.4% of male hybrids were correctly classified. Misclassified female and male hybrids resembled R. pomonella and one or the other parental species, respectively. Mean wing shapes of hybrid females based on landmark measurements were novel, whereas those of males were intermediate between those of nonhybrids. Based on wing shapes + natural log (ln) centroid size, 90.9% of female and 66.7% of male hybrids were correctly classified. Hybrid females were misclassified as R. pomonella and more hybrid males as R. zephyria. Based on surstylus shape, 27.7% of male hybrids were correctly classified, with more being misclassified as R. pomonella. Results show wing shape + ln centroid size is the most useful measure for identifying female and male hybrids and that R. pomonella traits for aculeus length and/or wing shape appear dominant to those of R. zephyria in hybrid females.

AB Electrical penetration graph (EPG) monitoring has been used extensively to elucidate mechanisms of resistance in plants to insect herbivores with piercing-sucking mouthparts. Characterization of waveforms produced by insects during stylet probing is essential to the application of this technology. In the studies described herein, a four-channel Backus and Bennett AC-DC monitor was used to characterize EPG waveforms produced by adults of two economically important chinch bug species: southern chinch bug, Blissus insularis Barber, feeding on St. Augustinegrass, and western chinch bug, Blissus occiduus Barber, feeding on buffalograss. This is only the third time a heteropteran species has been recorded by using EPG; it is also the first recording of adult heteropterans, and the first of Blissidae. Probing of chinch bugs was recorded with either AC or DC applied voltage, no applied voltage, or voltage switched between AC and DC mid-recording, at input impedances ranging from 10(6) to 10(10)Omega, plus 10(13)Omega, to develop a waveform library. Waveforms exhibited by western and southern chinch bugs were similar, and both showed long periods of putative pathway and ingestion phases (typical of salivary sheath feeders) interspersed with shorter phases, termed transitional J wave and interruption. The J wave is suspected to be an X wave, that is, in EPG parlance, a stereotypical transition waveform that marks contact with a preferred ingestion tissue. The flexibility of using multiple input impedances with the AC-DC monitor was valuable for determining the electrical origin (resistance vs. electromotive force components) of the chinch bug waveforms. It was concluded that an input impedance of 10(7) Omega, with either DC or AC applied voltage, is optimal to detect all resistance-and electromotive force-component waveforms produced during chinch bug probing. Knowledge of electrical origins suggested hypothesized biological meanings of the waveforms, before time-intensive future correlation experiments by using histology, microscopy, and other techniques.

AB Pregnancy failure in livestock can result from failure to fertilize the oocyte or embryonic loss during gestation. The focus of this review is on cattle and factors affecting and mechanisms related to uterine insufficiency for pregnancy. A variety of factors contribute to embryonic loss and it may be exacerbated in certain animals, such as high-producing lactating dairy cows, and in some cattle in which estrous synchronization and timed AI was performed, due to reduced concentrations of reproductive steroids. Recent research in beef cattle induced to ovulate immature follicles and in lactating dairy cows indicates that deficient uterine function is a major factor responsible for infertility in these animals. Failure to provide adequate concentrations of estradiol before ovulation results in prolonged effects on expression and localization of uterine genes and proteins that participate in regulating uterine functions during early gestation. Furthermore, progesterone concentrations during early gestation affect embryonic growth, interferontau production, and uterine function. Therefore, an inadequate uterine environment induced by insufficient steroid concentrations before and after ovulation could cause early embryonic death either by failing to provide an adequate uterine environment for recognition of embryo signaling, adhesion, and implantation or by failing to support appropriate embryonic growth, which could lead to decreased conceptus size and failed maternal recognition of pregnancy.

PREGNANCY ESTABLISHMENT
AB Reproductive failure in livestock can result from failure to fertilize the oocyte or embryonic loss during gestation. Although fertilization failure occurs, embryonic mortality represents a greater contribution to reproductive failure. Reproductive success varies among species and production goals but is measured as a binomial trait (i.e., pregnancy), derived by the success or failure of multiple biological steps. This review focuses primarily on follicular characteristics affecting oocyte quality, fertilization, and embryonic health that lead to pregnancy establishment in beef cattle. When estrous cycles are manipulated with assisted reproductive technologies and ovulation is induced, duration of proestrus (i.e., interval from induced luteolysis to induced ovulation), ovulatory follicle growth rate, and ovulatory follicle size are factors that affect the maturation of the follicle and oocyte at induced ovulation. The most critical maturational component of the ovulatory follicle is the production of sufficient estradiol to prepare follicular cells for luteinization and progesterone synthesis and prepare the uterus for pregnancy. The exact roles of estradiol in oocyte maturation remain unclear, but cows that have lesser serum concentrations of estradiol have decreased fertilization rates and decreased embryo survival on d 7 after induced ovulation. When length of proestrus is held constant, perhaps the most practical follicular measure of fertility is ovulatory follicle size because it is an easily measured attribute of the follicle that is highly associated with its ability to produce estradiol.

AB Conceptus losses in livestock occur throughout gestation. The uterus and the embryo-placenta-fetus play interconnected roles in these losses, the details of which depend on the period of gestation and the species. Studies in sheep and pigs have indicated that the uterine glands are essential for full fertility, based on experiments where gland development was reduced through the use of exogenous hormones. In sheep and cattle, normally the uterus is well able to support more than a single fetus although these species differ in the consequences of multiple births. When 2 conceptuses are present, the placentas of cattle often anastomose, putting 1 fetus at risk if the other is lost. One likely reason this does not occur in sheep is because sheep embryos undergo intrauterine migration, similar to pigs. In pigs, the relatively equidistant separation of conceptuses is likely to be essential for optimizing conceptus survival as is the simultaneous and uniform elongation of blastocysts that occurs during the time of maternal recognition of pregnancy. Other studies in pigs have indicated that the size of the uterus influences litter size and therefore fetal losses. In response to crowded intrauterine conditions in the pig, increased conceptus losses begin to occur between d 30 and 40 of pregnancy, and further losses occur sporadically during later gestation. There is evidence that improved fetal erythropoiesis can reduce these losses. Other studies indicated that profound changes in placental development occurred under crowded intrauterine conditions that may contribute to losses during late gestation. Reductions in placental stroma formation may compromise the ability of the pig placenta to adapt to reduced uterine space. Consistent with this, both hyaluronan and hyaluronidase activity are decreased in the placentas of small compared with large fetuses. These results indicate that improvements in placental stroma formation could improve placental ability to compensate for reduced intrauterine space, resulting in increased placental function and reduced fetal losses during late gestation.

AB Lysozyme is a 1,4-beta-N-acetylmuramidase that has antimicrobial properties. The objective of this experiment was to determine if lysozyme in nursery diets improved growth performance and gastrointestinal health of pigs weaned from the sow at 24 d of age. Two replicates of 96 pigs (192 total; 96 males, 96 females) were weaned from the sow at 24 d of age, blocked by BW and gender, and then assigned to 1 of 24 pens (4 pigs/pen). Each block was randomly assigned 1 of 3 dietary treatments for 28 d:control (two 14-d phases), control + antibiotics (carbadox/copper sulfate), or control + lysozyme (100 mg/kg diet). Pigs were weighed and blood sampled on d 0, 14, and 28 of treatment. Blood was analyzed for plasma urea nitrogen (PUN) and IgA. At 28 d, pigs were killed, and samples of jejunum and ileum were collected and fixed for intestinal morphology measurements. An additional jejunum sample was taken from the 12 pigs with the median BW per treatment to determine transepithelial electrical resistance (TER). Pigs consuming antibiotics or lysozyme grew at a faster rate than control pigs (0.433 +/- 0.009 and 0.421 +/- 0.008 vs. 0.398 +/- 0.008 kg/d, respectively; P < 0.03), which resulted in heavier ending BW (20.00 +/- 0.31, 19.8 +/- 0.29, and 18.83 +/- 0.32 kg, respectively; P < 0.03). Feed intake was not different (P > 0.48), but G:F was improved in pigs consuming antibiotics or lysozyme (0.756 +/- 0.014, 0.750 +/- 0.021, and 0.695 +/- 0.019 kg/kg; P < 0.05). Immunoglobulin A (P < 0.03) and PUN (P < 0.01) increased during the experiment, regardless of dietary treatment (P > 0.48). Dietary treatment did not affect TER (P > 0.37), but gilts had lower TER compared with barrows (P < 0.04). No differences in villi height or crypt depth were observed in the ileum (P > 0.53). However, jejunum villi height was increased and crypt depth was decreased in pigs consuming antibiotics or lysozyme (P < 0.001), resulting in an increased villi height:crypt depth of 72% (P < 0.001). Thus, we concluded that lysozyme is a suitable alternative to carbadox/copper sulfate diets fed to pigs weaned from the sow at 24 d of age.

AB Gilts that reach puberty at an earlier age with more backfat have greater lifetime productivity. Increased growth rates generally promote earlier age at first estrus; however, an association of age at first estrus with discrete measures of body fatness remains controversial. We tested the hypothesis that metabolic state as determined by concentrations of plasma urea nitrogen (PUN), which reflect lean tissue growth, were correlated with age at first estrus. Blood samples were collected from gilts (n = 337) at 102, 123, and 145 d of age during development. Concentrations of albumin, creatinine, glucose, and PUN were determined. Body weight and backfat thickness were determined at each time point. From 130 to 240 d of age, gilts were monitored for first pubertal estrus. Concentrations of creatinine increased whereas concentrations of glucose decreased with increasing age (P < 0.0001). Concentrations of albumin and PUN remained relatively stable throughout development. Average daily BW gain (r = 0.22) and change in backfat thickness (r = 0.29) had a positive phenotypic correlation (P < 0.0001) with PUN at 145 d of age. Concentrations of PUN at 102 and 123 d of age were not phenotypically correlated with pubertal age, but there was a moderately negative phenotypic correlation (r = -0.22; P < 0.0001) of PUN at 145 d of age with age at first estrus along with a negative genetic correlation (r = -0.42). The relationship of PUN with age at first estrus shifted from liner to quadratic with advancing age. These data demonstrate that near the age at which gilts are selected for entry into the breeding unit, those with greater PUN have increased BW and backfat thickness and display pubertal estrus earlier but that PUN does not account for additional variation in age at first estrus beyond growth rate or backfat. It is concluded that PUN can be used to select gilts with increased efficiency of nutrient use without negatively impacting pubertal development.

AB Myofibrillar protein turnover is a key component of muscle growth and degeneration, requiring proteolytic enzymes to degrade the skeletal muscle proteins. The objective of this study was to investigate the role of the calpain proteolytic system in muscle growth development using mu-calpain knockout (KO) mice in comparison with control wild-type (WT) mice, and evaluate the subsequent effects of silencing this gene on other proteolytic systems. No differences in muscle development between genotypes were observed during the early stages of growth due to the up regulation of other proteolytic systems. The KO mice showed significantly greater m-calpain protein abundance (P < 0.01) and activity (P < 0.001), and greater caspase 3/7 activity (P < 0.05). At 30 wk of age, KO mice showed increased protein: DNA (P < 0.05) and RNA: DNA ratios (P < 0.01), greater protein content (P < 0.01) at the expense of lipid deposition (P < 0.05), and an increase in size and number of fast-twitch glycolytic muscle fibers (P < 0.05), suggesting that KO mice exhibit an increased capacity to accumulate and maintain protein in their skeletal muscle. Also, expression of proteins associated with muscle regeneration (neural cell adhesion molecule and myoD) were both reduced in the mature KO mice (P < 0.05 and P < 0.01, respectively), indicating less muscle regeneration and, therefore, less muscle damage. These findings indicate the concerted action of proteolytic systems to ensure muscle protein homeostasis in vivo. Furthermore, these data contribute to the existing evidence of the importance of the calpain system's involvement in muscle growth, development, and atrophy. Collectively, these data suggest that there are opportunities to target the calpain system to promote the growth and/or restoration of skeletal muscle mass.

AB Two experiments were conducted to determine the DE and ME content of corn distillers dried grains with solubles (corn-DDGS) containing variable ether extract (EE) concentrations and to develop DE and ME prediction equations based on chemical composition. Ether extract content of corn-DDGS ranged from 4.88 to 10.88% (DM basis) among 4 corn-DDGS samples in Exp. 1 and from 8.56 to 13.23% (DM basis) among 11 corn-DDGS samples in Exp. 2. The difference in concentration of total dietary fiber (TDF) and NDF among the 4 corn-DDGS sources was 2.25 and 3.40 percentage units, respectively, in Exp. 1 but was greater among the 11 corn-DDGS sources evaluated in Exp. 2, where they differed by 6.46 and 15.18 percentage units, respectively. The range in CP and ash were from 28.97 to 31.19% and 5.37 to 6.14%, respectively, in Exp. 1 and from 27.69 to 32.93% and 4.32 to 5.31%, respectively, in Exp. 2. Gross energy content among corn-DDGS samples varied from 4,780 to 5,113 kcal/kg DM in Exp. 1 and from 4,897 to 5,167 kcal/kg DM in Exp. 2. In Exp. 1, the range in DE content was from 3,500 to 3,870 kcal/kg DM and ME content varied from 3,266 to 3,696 kcal/kg DM. There were no differences in ME:DE content among the 4 corn-DDGS sources in Exp. 1, but ME:GE content differed (P = 0.04) among sources (66.82 to 74.56%). In Exp. 2, the range in DE content among the 11 corn-DDGS sources was from 3,474 to 3,807 kcal/kg DM and ME content varied from 3,277 to 3,603 kcal/kg DM. However, there were no differences in DE:GE, ME:DE, or ME:GE among sources in Exp. 2. In Exp. 1, no ingredient physical or chemical measurement [bulk density (BD), particle size, GE, CP, starch, TDF, NDF, ADF, hemicellulose, EE, or ash)] was statistically significant at P <= 0.15 to predict DE or ME content in corn-DDGS. In Exp. 2, the best fit DE equation was DE (kcal/kg DM) = 1,601 - (54.48 x % TDF) + (0.69 x % GE) + (731.5 x BD) [R-2 = 0.91, SE = 41.25]. The best fit ME equation was ME (kcal/kg DM) = 4,558 + (52.26 x % EE) - (50.08 x % TDF) [R-2 = 0.85, SE = 48.74]. Apparent total tract digestibility of several nutritional components such as ADF, EE, and N were quite variable among corn-DDGS sources in both experiments. These results indicate that although EE may be a good predictor of GE content in corn-DDGS, it is not a primary factor for predicting DE or ME content. Measures of dietary fiber, such as ADF or TDF, are more important than EE in determining the DE or ME content of corn-DDGS for growing pigs.

AB Distillers grains and distillers solubles are by-products of grain fermentation used to produce ethanol and contain greater concentrations of NDF and ADF, compared with other grains and concentrates they replace in feedlot diets. Typical finishing diets in the United States contain 8.3% and 9.0% roughage. Therefore, it is plausible that the dietary concentration of roughage can be altered when distillers grains are included in feedlot diets. The effects of roughage concentration in dry-rolled, corn-based diets containing wet distillers grains with solubles (WDGS) were evaluated in steers (n = 128; initial BW = 339 kg), using Calan gates. Each diet was based on dry-rolled corn and contained 25% WDGS with coarsely ground alfalfa hay (AH), replacing corn at 2% (AH-2), 6% (AH-6), 10% (AH-10), and 14% (AH-14) of DM. Feed offered was recorded daily, orts were measured weekly, and BW was measured on d 0, 1, 35, 70, 105, 140, 174, and 175. After commercial harvest and chilling, carcasses were evaluated on-line with a beef carcass grading camera to assess marbling and yield grade traits. The data were analyzed using the Mixed Procedure of SAS, in which contrast statements were used to separate linear and quadratic effects of AH inclusion. Decreasing concentrations of AH in the finishing diet resulted in a tendency for a quadratic response (P = 0.07) in final BW, where BW increased from 2 to 6% AH inclusion but then decreased from 6 to 14% inclusion. Similarly, ADG from d 0 to end responded quadratically (P < 0.01), in which ADG increased from 2 to 6% yet subsequently decreased from 6 to 14% AH inclusion. Dry matter intake from d 0 to end increased linearly (P = 0.02) as AH inclusion increased in the diet, whereas G:F increased from 2 to 6% AH inclusion and then decreased linearly (P < 0.01) from 6 to 14% AH inclusion. Concentration of AH in the finishing diet did not affect HCW, marbling score, or the proportion of cattle grading USDA choice (P >= 0.18). However, dressing percent and LM area did respond in a quadratic manner (P < 0.02), in which they decreased from 2 to 10% AH inclusion and increased from 10 to 14% AH in the diet. Yield grade and adjusted 12th rib fat responded quadratically (P < 0.01), in which both increased from 2 to 6% AH inclusion and decreased from 6 to 14% inclusion. Analysis of responses of G:F and ADG on AH predict the apex at 3% and 7% for G:F and ADG, respectively, when fed in diets containing 25% WDGS.

AB Trans-2-hexenal (T2H), a plant-produced aldehyde, was intermittently pumped over a 7 d period into a small, bench top model of stored corn (nonsterile, moisture content about 23%). Naturally occurring bacteria and fungi, including added Aspergillus flavus, grew rapidly on corn not treated with T2H vapor. However, intermittently pumped T2H (30 min per 2 h or 30 min per 12 h) significantly reduced bacterial and fungal viable populations, with nearly 100% fungal viability loss observed after either (1) one day of pumping at the 30 min per 2 h rate or (2) pumping cycles of 30 min per 12 h period over the initial 48 to 72 h of incubation. Data suggest that short-term intermittent fumigation of stored corn with T2H could prevent growth of bacteria and mycotoxigenic fungi such as A. flavus.

AB The study evaluated the efficacy of integrated ultraviolet-C light (UVC) and low-dose gamma irradiation treatments to inactivate mixed strains of Escherichia coli O157:H7 and Salmonella enterica on inoculated whole grape tomatoes. A mixed bacterial cocktail composed of a 3 strain mixture of E. coli O157:H7 (C9490, E02128, and F00475) and a 3 serotype mixture of S. enterica (S. Montevideo G4639, S. Newport H1275, and S. Stanley H0558) was used based on their association with produce-related outbreaks. Spot inoculation (50 to 100 mL) on tomato surfaces was performed to achieve a population of appropriately 10(7-8) CFU/tomato. Inoculated tomatoes were subjected to UVC (253.7 nm) dose of 0.6 kJ/m(2) followed by 4 different low doses of gamma irradiations (0.1 kGy, 0.25 kGy, 0.5 kGy, 0.75 kGy). The fate of background microflora (mesophilic aerobic) including mold and yeast counts were also determined during storage at 5 degrees C over 21 d. Integrated treatment significantly (P < 0.05) reduced the population of target pathogens. Results indicate about 3.4 +/- 0.3 and 3.0 +/- 0.1 log CFU reduction of E. coli O157:H7 and S. enterica, respectively, per tomato with UVC (0.6 kJ/m(2)) and 0.25 kGy irradiation. More than a 4 log and higher reduction (>5 log) per fruit was accomplished by combined UVC treatment with 0.5 kGy and 0.75 kGy irradiation, respectively, for all tested pathogens. Furthermore, the combined treatment significantly (P < 0.05) reduced the native microflora compared to the control during storage. The data suggest efficacious treatment strategy for produce indicating 5 or higher log reduction which is consistent with the recommendations of the Natl. Advisory Committee on Microbiological Criteria for Foods.

This article describes a data processing step that impacts sodium intake estimates, reasons for discontinuing the step, and implications of its discontinuation. This step, termed salt adjustment, was performed in US Department of Agriculture (USDA) dietary intake surveys from 1985 through 2008. In What We Eat in America (WWEIA), the dietary intake interview component of the National Health and Nutrition Examination Survey (NHANES), the salt content of specific foods was reduced on the basis of a question about household use of salt in cooking. For individuals whose households used salt in cooking occasionally or less often, some or all of the salt attributable to home preparation was removed from foods that typically have salt added during preparation and were obtained from the store. The growing availability of preprepared foods in stores challenges the validity of using store purchase as a proxy indicator of home food preparation, and increased restaurant/fast-food consumption implies fewer reported foods are eligible for the procedure. In addition, USDA's Automated Multiple-Pass Method for the 24-hour dietary recall provides accurate sodium intake estimates without applying the salt-adjustment step. The final WWEIA, NHANES data release to contain salt-adjusted sodium data was 2007-2008. When assessing the effectiveness of sodium-reduction efforts over time, the nutrition community (eg, researchers, analysts, providers) must be aware of this change in WWEIA, NHANES beginning in 2009-2010 and account for it using appropriate baseline estimates.

AB The cattle tick, Rhipicephalus (Boophilus) microplus (Bm), and the sand fly, Phlebotomus papatasi (Pp), are disease vectors to cattle and humans, respectively. The purpose of this study was to characterize the inhibitor profile of acetylcholinesterases from Bm (BmAChE1) and Pp (PpAChE) compared to human and bovine AChE, in order to identify divergent pharmacology that might lead to selective inhibitors. Results indicate that BmAChE has low sensitivity (IC50 = 200 mu M) toward tacrine, a monovalent catalytic site inhibitor with sub micromolar blocking potency in all previous species tested. Similarly, a series of bis(n)-tacrine dimer series, bivalent inhibitors and peripheral site AChE inhibitors possess poor potency toward BmAChE. Molecular homology models suggest the rBmAChE enzyme possesses a W384F orthologous substitution near the catalytic site, where the larger tryptophan side chain obstructs the access of larger ligands to the active site, but functional analysis of this mutation suggests it only partially explains the low sensitivity to tacrine. In addition, BmAChE1 and PpAChE have low nanomolar sensitivity to some experimental carbamate anticholinesterases originally designed for control of the malaria mosquito, Anopheles gambiae. One experimental compound, 2-((2-ethylbutyl)thio)phenyl methylcarbamate, possesses >300-fold selectivity for BmAChE1 and PpAChE over human AChE, and a mouse oral LD50 of >1500 mg/kg, thus providing an excellent new lead for vector control.

AB The southern cattle tick Rhipicephalus (Boophilus) micro plus (Bm) is a vector of bovine babesiosis and anaplasmosis. Tick resistance to organophosphate (OP) acaricide involves acetylcholinesterase (AChE) insensitivity to OP and metabolic detoxification. Sequencing and in vitro expression of Bin genes encoding AChE allowed biochemical characterization of three BmAChEs expressed in tick synganglion. rBmAChE1, rBmAChE2 and rBmAChE3 exhibited substrate preference for acetylthiocholine, high substrate inhibition and sensitivity to AChE-specific inhibitors. OP-insensitivity mutations were demonstrated in rBmAChE1 and rBmAChE3. Gene silencing suggested functional complementation of BmAChEs in vivo. BmAChE genes were amplified in copy number and multiple transcript polymorphisms were expressed in individual tick synganglia for each of the BmAChEs, suggesting allelic diversity within individuals. Studies also identified a gene encoding AChE of the sand fly, Phlebotomus papatasi, a vector of leishmaniasis in humans and animals. Expression of recombinant P. papatasi AChE (rPpAChE) enabled biochemical characterization and identification of effective inhibitors that selectively target rPpAChE.

AB The mode of action of mosquito repellents remains a controversial topic. However, electrophysiological studies and molecular approaches have provided a better understanding of how repellents exert their effects. Here, we briefly discuss various theories of repellent action and present the current status of knowledge of the effects of repellents on olfactory and gustatory processes. These findings provide a framework for further development of existing repellents and the discovery of new compounds with novel modes of action. Published by Elsevier Inc.

AB The Arabidopsis gene AVP1 encodes an H+-pyrophosphatase that functions as a proton pump at the vacuolar membranes, generating a proton gradient across vacuolar membranes, which serves as the driving force for many secondary transporters on vacuolar membranes such as Na+/H+-antiporters. Overexpression of AVP1 could improve drought tolerance and salt tolerance in transgenic plants, suggesting a possible way in improving drought and salt tolerance in crops. The AVP1 was therefore introduced into peanut by Agrobacterium-mediated transformation. Analysis of AVP1-expressing peanut indicated that AVP1-overexpression in peanut could improve both drought and salt tolerance in greenhouse and growth chamber conditions, as AVP1-overexpressing peanuts produced more biomass and maintained higher photosynthetic rates under both drought and salt conditions. In the field, AVP1-overexpressing peanuts also outperformed wild-type plants by having higher photosynthetic rates and producing higher yields under low irrigation conditions.

AB A bundle of a few loblolly pine (Pinus taeda) cells are moisture-activated torsional actuators that twist multiple revolutions per cm length in direct proportion to moisture content. The bundles generate 10 N m kg(-1) specific torque during both twisting and untwisting, which is higher than an electric motor. Additionally, the bundles exhibit a moisture-activated, shape memory twist effect. Over 70% of the twist in a wetted bundle can be locked-in by drying under constraint and then released by rewetting the bundle. Our results indicate that hemicelluloses dominate the shape fixity mechanism and lignin is primarily responsible for remembering the bundle's original form. The bundles demonstrate proof of a high specific torque actuator with large angles of rotation and shape memory twist capabilities that can be used in microactuators, sensors, and energy harvesters.

AB Few studies have addressed the presence and bioactivity of endophytic fungi living in plantlets growing under in vitro conditions. After unfruitful attempts to grow axenic shoot cultures of the medicinal plant Smallanthus sonchifolius (yacon) were made, healthy shoots grew on half strength Murashigue and Skoog media supplemented with 2.2 mu M benzylaminopurine without sucrose. We isolated a fungus UM109 from these autotrophic tissue cultures and it was identified as Coniochaeta ligniaria using molecular, physiological and morphological methods. Dichloromethane extracts from C. ligniaria and its host S. sonchifolius exhibited antifungal activity against phytopathogenic fungi Colletotrichum acutatum, C. fragariae and C. gloeosporioides. Both extracts of C. ligniaria and S. sonchifolius were subjected to antifungal bioassay-directed fractionation using NMR spectroscopy and GC-FID analysis. Twelve antifungal fatty acids were identified and 8 out of the total were produced by the fungus and the plant including caproic, caprylic, myristic, palmitic, heptadecanoic, stearic, oleic and linoleic acids. Additionally, caproic, caprylic and palmitic acids were produced at high concentrations by the endophytic fungus and its host. The detection of these antifungal fatty acids produced by both C. ligniaria and S. sonchifolius suggests that these bioactive compounds may be partially responsible for the high resistance of S. sonchifolius to phytopathogenic fungal attacks. This finding also indicates the existence of an interesting chemical symbiosis between an endophytic fungus and its host. Furthermore, the isolation of C. ligniaria from tissue culture of S. sonchifolius demonstrates that plantlets growing in vitro as autotrophic cultures can shelter specific endophytic fungal communities. The use of autotrophic tissue cultures may become an important tool for studies on the taxonomy, ecology, evolution and biotechnological application of endophytes.

AB The interactions between fungi and plants can yield metabolites that are toxic in animal systems. Certain fungi are known to produce sesquiterpenoid trichothecenes, such as T-2 toxin, that are biotransformed by several mechanisms including glucosylation. The glucosylated forms have been found in grain and are of interest as potential reservoirs of T-2 toxin that are not detected by many analytical methods. Hence the glucosides of trichothecenes are often termed "masked" mycotoxins. The glucoside of T-2 toxin (T2-Glc) was linked to keyhole limpet hemocyanin and used to produce antibodies in mice. Ten monoclonal antibody (Mab)-producing hybridoma cell lines were developed. The Mabs were used in immunoassays to detect T2-Glc and T-2 toxin, with midpoints of inhibition curves (IC(50)s) in the low ng/mL range. Most of the Mabs demonstrated good cross-reactivity to T-2 toxin, with lower recognition of HT-2 toxin. One of the clones (2-13) was further characterized with in-depth cross-reactivity and solvent tolerance studies. Results suggest Mab 2-13 will be useful for the simultaneous detection of T-2 toxin and T2-Glc.

AB Pediatric drug development is hampered by biological, clinical, and formulation challenges associated with age-based populations. A primary cause for this lack of development is the inability to accurately predict ontogenic changes that affect pharmacokinetics (PK) in children using traditional preclinical animal models. In response to this issue, our laboratory has conducted a proof-of-concept study to investigate the potential utility of juvenile pigs to serve as surrogates for children during preclinical PK testing of selected rifampin dosage forms. Pigs were surgically modified with jugular vein catheters that were externalized in the dorsal scapular region and connected to an automated blood sampling system (PigTurn-Culex-L). Commercially available rifampin capsules were administered to both 20 and 40 kg pigs to determine relevant PK parameters. Orally disintegrating tablet formulations of rifampin were also developed and administered to 20 kg pigs. Plasma samples were prepared from whole blood by centrifugation and analyzed for rifampin content by liquid chromatography-tandem mass spectrometry. Porcine PK parameters were determined from the resultant plasma-concentration time profiles and contrasted with published rifampin PK data in human adults and children. Results indicated significant similarities in dose-normalized absorption and elimination parameters between pigs and humans. Moreover, ontogenic changes observed in porcine PK parameters were consistent with ontogenic changes reported for human PK. These results demonstrate the potential utility of the juvenile porcine model for predicting human pediatric PK for rifampin. Furthermore, utilization of juvenile pigs during formulation testing may provide an alternative approach to expedite reformulation efforts during pediatric drug development.

AB Background: Animal studies have shown that vitamin K treatment reduced vascular calcification, but human data are limited.
Objective: We determined the association between vitamin K status and coronary artery calcium (CAC) progression in the Multi-Ethnic Study of Atherosclerosis by using a case-cohort design.
Design: Serum phylloquinone (vitamin K1) was measured in 296 participants with extreme CAC progression and 561 randomly selected participants without extreme CAC progression; all subjects had baseline and follow-up CAC measures (mean follow-up: 2.5 y). A serum vitamin K1 concentration was considered low at <1.0 nmol/L (the distribution median). Outcomes were replicated by using post hoc per-protocol analyses of a vitamin K1 supplementation trial.
Results: The OR (95% CI) for extreme CAC progression for subjects with low serum vitamin K1 compared with subjects without extreme CAC progression was 1.34 (0.94, 1.90; NS) when adjusted for demographics and confounders. A significant interaction between low vitamin K1 and antihypertension medication use was detected (P = 0.016). Hypertension medication users with low serum vitamin K1 were more likely to have extreme CAC progression than were medication users without extreme CAC progression [OR (95% CI): 2.37 (1.38, 4.09)]. In replication, baseline antihypertensive medication users in the supplementation group had less CAC progression than did those in the control group [adjusted mean SEM of the 3-y CAC change was +5 +/- 20 Agatston units (AU) in the vitamin K1 group (n = 40) and +44 +/- 13 AU in the placebo group (n = 49); P < 0.01]
Conclusions: Although the point estimate of our primary analysis suggests low serum vitamin K1 is associated with greater CAC progression, the difference was NS. Low serum vitamin K1 was significantly associated with CAC progression in antihypertension medication users, which, to our knowledge, is a novel finding conditionally replicated by using an independent sample. Intervention trials are needed to determine whether improving serum vitamin K1 reduces CAC progression, especially in hypertensive individuals.

AB Previous reports have indicated that a small proportion of cattle shedding high levels of Escherichia coli O157:H7 is the main source for transmission of this organism between animals. Cattle achieving a fecal shedding status of 10(4) CFU of E. coli O157:H7/gram or greater are now referred to as supershedders. The aim of this study was to investigate the contribution of E. coli O157:H7 strain type to supershedding and to determine if supershedding was restricted to a specific set of E. coli O157:H7 strains. Fecal swabs (n = 5,086) were collected from cattle at feedlots or during harvest. Supershedders constituted 2.0% of the bovine population tested. Supershedder isolates were characterized by pulsed-field gel electrophoresis (PFGE), phage typing, lineage-specific polymorphism assay (LSPA), Stx-associated bacteriophage insertion (SBI) site determination, and variant analysis of Shiga toxin, tir, and antiterminator Q genes. Isolates representing 52 unique PFGE patterns, 19 phage types, and 12 SBI clusters were obtained from supershedding cattle, indicating that there is no clustering to E. coli O157:H7 genotypes responsible for supershedding. While being isolated directly from cattle, this strain set tended to have higher frequencies of traits associated with human clinical isolates than previously collected bovine isolates with respect to lineage and tir allele, but not for SBI cluster and Q type. We conclude that no exclusive genotype was identified that was common to all supershedder isolates.

AB The development from egg to pupation is followed for the wasp Eretmocerus mundus, parasitizing the whitefly Bemisia tabaci. We elucidate and describe structural details, histological developments and changes that the different parasitoid and host tissues have undergone during parasitism. These include the presence and apparent function of very large salivary glands, which probably produce substances that help to regulate the host's decomposition and parasitoid nutrition. Moreover, the gut of all instars is devoid of both peritrophic membrane and microvilli and, in the early instars, it has squamous rather than columnar epithelial cells. Differing from many other parasitoids, the E. mundus larva usually does not come into contact with the host tissues and does not devour the entire host during its development.
The possible reasons for the developmental mechanisms, as well as the functions of the host capsule that envelopes the parasitoid, are discussed. (C) 2013 Elsevier Ltd. All rights reserved.

AB Dioscorea bulbifera, an Asian vine, is invasive in the southeastern USA. It rarely flowers but propagates from potato-like bulbils formed in leaf axils, which persist into the subsequent growing season. Lilioceris cheni Gressitt and Kimoto, a foliage-feeding beetle (Coleoptera: Chrysomelidae: Criocerinae) from Nepal, had been tested, proven to be a specialist and approved for release as a biological control agent. Regulatory delays, however, resulted in the demise of quarantine-held colonies, and acquisition of new Nepalese stock proved untenable. Searches then undertaken in southern China resulted in the collection of over 300 similar beetles. Two Chinese Lilioceris species were identified: one confirmed to be L. cheni and the other identified as Lilioceris egena (Weise). Mitochondrial analysis revealed an exact DNA match between some Chinese and one of the two Nepalese c oxidase subunit I haplotypes and all Chinese L. cheni haplotypes clustered as a single species but the comingling of the two species aroused concerns over possible hybridisation. These concerns were allayed by nuclear D2 analysis showing the absence of dual parental sequences. Nonetheless, diligence was exercised to ensure that the Chinese strains were safe to release. Abridged host testing using critical test species verified specificity. Caged releases during autumn 2011 documented the ability of adult beetles to overwinter in south Florida despite a prolonged lack of foliage. Open releases the following year produced vigorous populations that caused extensive defoliation. Preliminary observations indicate that L. cheni now contributes to the control of D. bulbifera and the bulbil-feeding L. egena should complement these effects if its host range proves appropriate.

AB Chinese tallow, Triadica sebifera, is an invasive weed that infests natural and agricultural areas of the south-eastern USA. A candidate insect for biological control of Chinese tallow has been studied under quarantine conditions. The biology and host range of a primitive leaf-feeding beetle, Heterapoderopsis bicallosicollis, were examined between July 2008 and February 2010. H. bicallosicollis adults fed on 16 of 29 non-target species and survived >10 days on all 29 species, more than the number of days that adults survived when deprived of food. Additionally, adult feeding, oviposition and partial larval development occurred on a Florida endangered species, Heterosavia bahamensis. These data indicated that H. bicallosicollis adult feeding and oviposition may not be limited to the target weed and included several valued North American natives. Therefore, as its release could pose unacceptable risks, testing of this species was discontinued and the quarantine colony destroyed.

AB Agriculture in the United States (US) cycles large quantities of nitrogen (N) to produce food, fuel, and fiber and is a major source of excess reactive nitrogen (Nr) in the environment. Nitrogen lost from cropping systems and animal operations moves to waterways, groundwater, and the atmosphere. Changes in climate and climate variability may further affect the ability of agricultural systems to conserve N. The N that escapes affects climate directly through the emissions of nitrous oxide (N2O), and indirectly through the loss of nitrate (NO3 (-)), nitrogen oxides (NO (x) ) and ammonia to downstream and downwind ecosystems that then emit some of the N received as N2O and NO (x) . Emissions of NO (x) lead to the formation of tropospheric ozone, a greenhouse gas that can also harm crops directly. There are many opportunities to mitigate the impact of agricultural N on climate and the impact of climate on agricultural N. Some are available today; many need further research; and all await effective incentives to become adopted. Research needs can be grouped into four major categories: (1) an improved understanding of agricultural N cycle responses to changing climate; (2) a systems-level understanding of important crop and animal systems sufficient to identify key interactions and feedbacks; (3) the further development and testing of quantitative models capable of predicting N-climate interactions with confidence across a wide variety of crop-soil-climate combinations; and (4) socioecological research to better understand the incentives necessary to achieve meaningful deployment of realistic solutions.

AB Biodiversity has been described as the diversity of life on earth within species, among species, and among ecosystems. The rate of biodiversity loss due to human activity in the last 50 years has been more rapid than at any other time in human history, and many of the drivers of biodiversity loss are increasing, including habitat loss, overexploitation, invasive species, climate change, and pollution, including pollution from reactive nitrogen (Nr). Of these stressors, climate change and Nr from anthropogenic activities are causing some of the most rapid changes. Climate change is causing warming trends that result in poleward and elevational range shifts of flora and fauna, and changes in phenology, particularly the earlier onset of spring events and migration, and lengthening of the growing season. Nitrogen (N) enrichment can enhance plant growth, but has been shown to favor, fast-growing, sometimes invasive, species over native species adapted to low N conditions. Although there have been only a few controlled studies on climate change and N interactions, inferences can be drawn from various field observations. For example, in arid ecosystems of southern California, elevated N deposition and changing precipitation patterns have promoted the conversion of native shrub communities to communities dominated by annual non-native grasses. Both empirical studies and modeling indicate that N and climate change can interact to drive losses in biodiversity greater than those caused by either stressor alone. Reducing inputs of anthropogenic Nr may be an effective mitigation strategy for protecting biodiversity in the face of climate change.

AB Insect herbivory can produce a pulse of mineral nitrogen (N) in soil from the decomposition of frass and cadavers. In this study, we examined how diet quality affects rates of N and carbon (C) mineralization from grasshopper frass and cadavers. Frass was collected from grasshoppers fed with natural or meridic diets which varied in N content. Frass was also collected from naturally foraging grasshoppers. Nitrogen concentration of frass was directly proportional to diet N, but N content of cadavers was not affected by diet. Incubations of soil plus frass were performed at constant soil moisture and temperature (15A degrees C) for 28 days, after which levels of mineral N (KCl extract) were determined. About 44 % of C and N from the cadavers were mineralized after the 28-day incubation. Carbon mineralization of frass was not affected by diet or frass N but varied considerably among different food treatments: from 15 to 46 % of the C in frass was released as carbon dioxide. Generally, frass with C/N ratio greater than 20 resulted in net immobilization of N. Results suggest that much of the N in grasshopper frass and cadavers is labile and rapidly available for plants, depending on the quality of food consumed by the grasshoppers.

AB Soft wheat milling quality assessment typically begins in the later stages of wheat breeding programmes and continues after cultivar release in commercial milling and processing operations. Near-infrared (NW) hyperspectral (HS) image analysis, a technique that is gaining interest in food and pharmaceutical inspection research, was explored as an alternative procedure for milling quality evaluation. Three quality properties were studied, flour yield (the weight fraction of flour to whole grain), softness equivalent (a gauge of how easily flour is released from the kernel during break), and sucrose solvent retention capacity (SRC, related to arabinoxylans, which influence water absorption during dough mixing) because of their high degree of heritability and influence on soft wheat quality. NIR HS reflectance images (1000-1700 nm) of non-touching kernels were collected on more than 120 pure cultivars or advanced lines of soft red and white wheat. Five morphological properties (area, elliptical eccentricity and major and minor axis lengths, and ellipsoidal volume) and three spectral properties (principal component scores 1-3) were exhaustively examined in multiple linear regression models for each quality property and in nonparametric classification into low, medium, and high groups using texture properties (contrast, correlation, energy, and homogeneity) calculated from grey-level co-occurrence matrices of principal component scores images. Results indicated that softness equivalent exhibited the highest correlation with HS properties, while sucrose SRC had the lowest correlation. The combination of morphological and spectral properties produced better models than either property group alone. However, because of the inherent chemical and physical complexities of wheat, HS imaging will not be sufficient so as to replace actual pilot milling procedures.

AB A rapid dielectric-based method was used to non-destructively determine the moisture content and bulk density of peanut-hull pellets from free-space measurement of their dielectric properties at microwave frequencies. For moisture content determination, a permittivity-based function was used that permits moisture prediction independent of bulk density from measurement of the dielectric properties at microwave frequencies. For bulk density determination, an analytical expression was obtained from a representation of the dielectric properties in the complex plane. Results of moisture and density prediction from measurement of the dielectric properties are shown at 5, 10, and 15 GHz at 22 degrees C. Published by Elsevier Ltd on behalf of IAgrE.

AB Standing dead trees (snags) are an important component of forest ecosystems, providing foraging, nesting, and roosting substrate for a variety of vertebrates. We examined the effects of four forest regeneration treatments on residual snag density and compared those with densities found in unharvested, naturally regenerated forests (controls) during the second, fourth, and sixth year after timber harvest in mixed pine-hardwood forests of Arkansas and Oklahoma. Regeneration treatments were clearcut with snag creation, shelterwood, single-tree selection, and group selection. Density of large snags (>= 25.0 cm DBH) differed only during the sixth year after harvest, with shelterwoods having a lower density of large snags (1.0 snags/ha) than the control or group selection stands (4.0 and 4.2 snags/ha, respectively). Density of small snags (10.0-24.9 cm DBH) mirrored residual basal area, with controls and group-selection stands having the greatest snag densities. Creation of snags in clearcuts by injection with herbicides caused initial snag density in these areas to be greater than other treatments, but density in clearcuts declined sharply by 6 years after harvest. In the absence of snag creation, treatments such as shelterwoods that remove most trees may have snag densities below that required to address some management objectives without additional snag creation.

AB Frequently encountered parasite species impart strong selective pressures on host immune system evolution and are more apt to concurrently infect the same host, yet molecular impacts in light of this are often overlooked. We have contrasted immune responses in honey bees to two common eukaryotic endoparasites by establishing single and mixed-species infections using the long-associated parasite Crithidia mellificae and the emergent parasite Nosema ceranae. Quantitative polymerase chain reaction was used to screen host immune gene expression at 9 time points post inoculation. Systemic responses in abdomens during early stages of parasite establishment revealed conserved receptor (Down syndrome cell adhesion molecule, Dscam and nimrod C1, nimC1), signaling (MyD88 and Imd) and antimicrobial peptide (AMP) effector (Defensin 2) responses. Late, established infections were distinct with a refined 2 AMP response to C mellificae that contrasted starkly with a 5 AMP response to N. ceranae. Mixed species infections induced a moderate 3 AMPs. Transcription in gut tissues highlighted important local roles for Dscam toward both parasites and Imd signaling toward N. ceranae. At both systemic and local levels Dscam, MyD88 and Imd transcription was consistently correlated based on clustering analysis. Significant gene suppression occurred in two cases from midgut to ileum tissue: Dscam was lowered during mixed infections compared to N. ceranae infections and both C mellificae and mixed infections had reduced nimC1 transcription compared to uninfected controls. We show that honey bees rapidly mount complex immune responses to both Nosema and Crithidia that are dynamic over time and that mixed-species infections significantly alter local and systemic immune gene transcription.

AB Mitigating Gulf of Mexico hypoxia will require practices to reduce nitrate losses from tile drainage throughout the upper Mississippi River basin. Wetlands are a key practice to accomplish this via denitrification, but locations of feasible wetland sites will need to be determined on a watershed specific basis. This study's objective was to demonstrate that LiDAR topographic data can be used to identify feasible wetland locations in a 6500 ha watershed. in northern Illinois, and then estimate the impact on watershed nitrate loads from wetlands hypothetically constructed at those locations. The evaluation resulted in the identification of eleven sites where wetlands could intercept tile drainage from 30% of the watershed. The USDA AnnAGNPS model was used to estimate nitrate loads delivered to candidate wetlands during a 30-year period of simulated climate. The model results were consistent with discharge and nitrate loading regimes in the region. Nitrate reduction by the wetlands was estimated using a published regression model. The wetlands could reduce average watershed nitrate loads by 11-13%, a significant reduction from treating just 30% of the watershed with a single practice. Results showed a wide variation in N-removal performance among wetlands, due to varying contributing-to-wetland area ratios, and varying land uses that affected discharge and N loads among locations. A large wetland installed at the watershed outlet could achieve an estimated N-load reduction of 35% under relaxed siting criteria, but would require the added expense of roadway reconstruction. These conclusions are relevant for planning watershed conservation efforts and establishment of nutrient trading schemes. Published by Elsevier B.V.

AB Although nitrogen (N) deposition is a significant threat to herbaceous plant biodiversity worldwide, it is not a new stressor for many developed regions. Only recently has it become possible to estimate historical impacts nationally for the United States. We used 26 years (1985-2010) of deposition data, with ecosystem-specific functional responses from local field experiments and a national critical loads (CL) database, to generate scenario-based estimates of herbaceous species loss. Here we show that, in scenarios using the low end of the CL range, N deposition exceeded critical loads over 0.38, 6.5, 13.1, 88.6, and 222.1 million ha for the Mediterranean California, North American Desert, Northwestern Forested Mountains, Great Plains, and Eastern Forest ecoregions, respectively, with corresponding species losses ranging from <1% to 30%. When we ran scenarios assuming ecosystems were less sensitive (using a common CL of 10 kgha(-1)yr(-1), and the high end of the CL range) minimal losses were estimated. The large range in projected impacts among scenarios implies uncertainty as to whether current critical loads provide protection to terrestrial plant biodiversity nationally and urge greater research in refining critical loads for U.S. ecosystems.

AB Diadromous aquatic species that cross a diverse range of habitats (including marine, estuarine, and freshwater) face different effects of climate change in each environment. One such group of species is the anadromous Pacific salmon (Oncorhynchus spp.). Studies of the potential effects of climate change on salmonids have focused on both marine and freshwater environments. Access to a variety of estuarine habitat has been shown to enhance juvenile life-history diversity, thereby contributing to the resilience of many salmonid species. Our study is focused on the effect of sea-level rise on the availability, complexity, and distribution of estuarine, and low-freshwater habitat for Chinook salmon (Oncorhynchus tshawytscha), steelhead (anadromous O. mykiss), and coho salmon (O. kisutch) along the Oregon Coast under future climate change scenarios. Using LiDAR, we modeled the geomorphologies of five Oregon estuaries and estimated a contour associated with the current mean high tide. Contour intervals at 1- and 2-m increments above the current mean high tide were generated, and changes in the estuary morphology were assessed. Because our analysis relied on digital data, we compared three types of digital data in one estuary to assess the utility of different data sets in predicting the changes in estuary shape. For each salmonid species, changes in the amount and complexity of estuarine edge habitats varied by estuary. The simple modeling approach we applied can also be used to identify areas that may be most amenable to pre-emptive restoration actions to mitigate or enhance salmonid habitat under future climatic conditions.

AB Carbon storage and sequestration by urban trees in the United States was quantified to assess the magnitude and role of urban forests in relation to climate change. Urban tree field data from 28 cities and 6 states were used to determine the average carbon density per unit of tree cover. These data were applied to statewide urban tree cover measurements to determine total urban forest carbon storage and annual sequestration by state and nationally. Urban whole tree carbon storage densities average 7.69 kg C m(-2) of tree cover and sequestration densities average 0.28 kg C m(-2) of tree cover per year. Total tree carbon storage in U.S. urban areas (c. 2005) is estimated at 643 million tonnes ($50.5 billion value; 95% CI = 597 million and 690 million tonnes) and annual sequestration is estimated at 25.6 million tonnes ($2.0 billion value; 95% CI = 23.7 million to 27.4 million tonnes).

AB Urban particulate air pollution is a serious health issue. Trees within cities can remove fine particles from the atmosphere and consequently improve air quality and human health. Tree effects on PM2.5 concentrations and human health are modeled for 10 U.S. cities. The total amount of PM2.5 removed annually by trees varied from 4.7 tonnes in Syracuse to 64.5 tonnes in Atlanta, with annual values varying from $1.1 million in Syracuse to $60.1 million in New York City. Most of these values were from the effects of reducing human mortality. Mortality reductions were typically around 1 person yr(-1) per city, but were as high as 7.6 people yr(-1) in New York City. Average annual percent air quality improvement ranged between 0.05% in San Francisco and 0.24% in Atlanta. Understanding the impact of urban trees on air quality can lead to improved urban forest management strategies to sustain human health in cities. Published by Elsevier Ltd.

AB A putative terpene cyclase vir4, which is a member of a secondary metabolite cluster, has been deleted in Trichoderma virens to determine its function. The deletion mutants were compared for volatile production with the wild-type as well as two other Trichoderma spp. This gene cluster was originally predicted to function in the synthesis of viridin and viridiol. However, the experimental evidence demonstrates that this gene cluster is involved in the synthesis of volatile terpene compounds. The entire vir4-containing gene cluster is absent in two other species of Trichoderma, T. atroviride and T. reesei. Neither of these two species synthesizes volatile terpenes associated with this cluster in T. virens. We have thus identified a novel class of volatile fungal sesquiterpenes as well as the gene cluster involved in their biosynthesis. (C) 2013 Elsevier Inc. All rights reserved.

AB Ambrosia beetle fungiculture represents one of the most ecologically and evolutionarily successful symbioses, as evidenced by the 11 independent origins and 3500 species of ambrosia beetles. Here we document the evolution of a clade within Fusarium associated with ambrosia beetles in the genus Euwallacea (Coleoptera: Scolytinae). Ambrosia Fusarium Clade (AFC) symbionts are unusual in that some are plant pathogens that cause significant damage in naive natural and cultivated ecosystems, and currently threaten avocado production in the United States, Israel and Australia. Most AFC fusaria produce unusual clavate macroconidia that serve as a putative food source for their insect mutualists. AFC symbionts were abundant in the heads of four Euwallacea spp., which suggests that they are transported within and from the natal gallery in mandibular mycangia. In a four-locus phylogenetic analysis, the AFC was resolved in a strongly supported monophyletic group within the previously described Cade 3 of the Fusarium solani species complex (FSSC). Divergence-time estimates place the origin of the AFC in the early Miocene similar to 21.2 Mya, which coincides with the hypothesized adaptive radiation of the Xyleborini. Two strongly supported clades within the AFC (Clades A and B) were identified that include nine species lineages associated with ambrosia beetles, eight with Euwallacea spp. and one reportedly with Xyleborus ferrugineus, and two lineages with no known beetle association. More derived lineages within the AFC showed fixation of the clavate (club-shaped) macroconidial trait, while basal lineages showed a mix of clavate and more typical fusiform macroconidia. AFC lineages consisted mostly of genetically identical individuals associated with specific insect hosts in defined geographic locations, with at least three interspecific hybridization events inferred based on discordant placement in individual gene genealogies and detection of recombinant loci. Overall, these data are consistent with a strong evolutionary trend toward obligate symbiosis coupled with secondary contact and interspecific hybridization. (C) 2013 Elsevier Inc.

AB OBJECTIVE: Large portions promote intake among children, but little is known about the external influences of the eating environment on children's self-selected portion sizes. This research experimentally tested effects of the amount of entree available and serving spoon size on children's self-served entree portions and intakes at dinner meals. A secondary objective was to identify child and family predictors of self-served entree portion sizes.
DESIGN: A 2 x 2 within-subjects design was used, in which the amount of a pasta entree available for self-serving (275 vs 550 g) and the serving spoon size (teaspoon vs tablespoon) were systematically varied. The serving bowl size and portion sizes of all other foods offered were held constant across conditions. Conditions were spaced 1 week apart and randomly assigned. Weighed self-served entree portions and food intakes as well as demographics, maternal feeding styles and child/maternal anthropometrics were measured.
SUBJECTS: Participants were 60 ethnically diverse children aged 4-6 years and their mothers.
RESULTS: Mixed models revealed that children served themselves 40% more entree when the amount available was doubled (P < 0.0001) and 13% more when the serving spoon size was tripled (P < 0.05). Serving spoon size and the amount of entree available indirectly influenced children's intake, with larger self-served portion sizes related to greater entree intakes (P < 0.0001). Greater self-served portions and energy intakes at the meal were seen among those children whose mothers reported indulgent or authoritarian feeding styles (P < 0.001).
CONCLUSION: Children's self-served portion sizes at meals are influenced by size-related facets of the eating environment and reflect maternal feeding styles.

AB Background: Ara h 1, a vicilin; Ara h 2, a 2S albumin; and Ara h 3, a legumin, are major peanut allergens. Ara h 2 is an important predictor of clinical reactivity to peanut, but cosensitization to all 3 allergens is correlated with the severity of patients' symptoms.
Objective: We investigated whether cosensitization to these 3 allergens is caused by IgE cross-reactivity, despite the fact that they do not display obvious structural or sequence similarities.
Methods: IgE cross-inhibitions were performed with purified Ara h 1, Ara h 2, and Ara h 3 and IgG-depleted sera from 10 patients with peanut allergy. After an in silico search for similar peptides, IgE ELISA inhibition assays with synthetic peptides were performed.
Results: Ara h 2 inhibited IgE binding to Ara h 1 (average, 86% +/- 13%) and Ara h 3 (average, 96% +/- 6%). IgE binding to Ara h 2 was inhibited by Ara h 1 by 78% +/- 15% and by Ara h 3 by 80% +/- 6%. A subsequent sequence comparison showed that these nonhomologous allergens contained several similar surface-exposed peptides. IgE binding to Ara h 2-derived peptides was completely inhibited by Ara h 1 and Ara h 3. A mixture of these peptides reduced IgE binding to Ara h 1 and Ara h 3 by 20% to 60% and to Ara h 2 by 49% to 89%.
Conclusion: Occurrence of similar sequences in the 3 major peanut allergens accounts for the high extent of cross-reactivity among them.

AB A number of studies concluded that peak pyrolysis temperature determines essential biochar properties: surface functional group, fixed carbon content, O/C, H/C, and BET surface area. Chemical (most importantly oxygen-containing surface functionalities), rather than physical (surface area) property of biochar dictates its ability to stabilize heavy metals in soil. Labile carbon fraction of biochar is rich in heavy metal coordinating functionalities, and recalcitrant carbon fraction is necessary for the long-term stability in soil. To produce desirable biochar properties With minimal time and cost, the slow pyrolysis platform must be optimized not only for the peak temperature, but additional parameters including the residence time and heating rate. In this study, time courses of biomass slow pyrolysis were investigated in the real time using a time-resolved (0.5 s) in situ Diffuse Reflectance Infrared Fourier Transform (DRIFTs) to continuously monitor the changes in surface functionality. The greatest change in surface functionality was observed at 200-500 degrees C from both in situ DRIFTs (during heating up at 10 degrees C min(-1) to reach the peak temperature) as well as ex situ (after a set residence time at the peak temperature) proximate, ultimate, attenuated total reflectance (ATR)-FTIR, and H-1 NMR analyses of slow/fast pyrolysis and activated biochars. The FTIR spectral features at respective temperatures during in situ pyrolysis of lignocellulosic feedstock matched the peak temperature of post-production analysis. The FTIR peaks attributable to the oxygen-containing functional groups dramatically diminished after 20 min residence time. Quantitative relationships were observed between parameters attributable to the aromatic characteristics: (1) baseline FTIR absorbance and (2) atomic H/C ratio with the fixed carbon content of biochar.

AB Advanced mathematical models have the potential to capture the complex metabolic and physiological processes that result in energy expenditure (EE). Study objective is to apply quantile regression (QR) to predict EE and determine quantile-dependent variation in covariate effects in nonobese and obese children. First, QR models will be developed to predict minute-by-minute awake EE at different quantile levels based on heart rate (HR) and physical activity (PA) accelerometry counts, and child characteristics of age, sex, weight, and height. Second, the QR models will be used to evaluate the covariate effects of weight, PA, and HR across the conditional EE distribution. QR and ordinary least squares (OLS) regressions are estimated in 109 children, aged 5-18 yr. QR modeling of EE outperformed OLS regression for both nonobese and obese populations. Average prediction errors for QR compared with OLS were not only smaller at the median tau = 0.5 (18.6 vs. 21.4%), but also substantially smaller at the tails of the distribution (10.2 vs. 39.2% at tau = 0.1 and 8.7 vs. 19.8% at tau = 0.9). Covariate effects of weight, PA, and HR on EE for the nonobese and obese children differed across quantiles (P < 0.05). The associations (linear and quadratic) between PA and HR with EE were stronger for the obese than nonobese population (P < 0.05). In conclusion, QR provided more accurate predictions of EE compared with conventional OLS regression, especially at the tails of the distribution, and revealed substantially different covariate effects of weight, PA, and HR on EE in nonobese and obese children.

AB In this paper, we present a model of prehistoric southwestern Colorado maize productivity. The model is based on a tree-ring reconstruction of water-year precipitation for Mesa Verde for the period A.D. 480 to 2011. Correlation of historic Mesa Verde precipitation with historic precipitation at 11 other weather stations enabled the construction of an elevation-dependent precipitation function. Prehistoric water-year precipitation values for Mesa Verde together with the elevation-dependent precipitation function allowed construction of the elevation of southwest Colorado precipitation contours for each year since A.D. 480, including the 30-cm contour, which represents the minimum amount of precipitation necessary for the production of maize and the 50-cm contour, which represents the optimum amount of precipitation necessary for the production of maize. In this paper, calculations of prehistoric maize productivity and field life for any specific elevation are also demonstrated. These calculations were performed using organic nitrogen measurements made on seven southwestern Colorado soil groups together with values of reconstructed water-year precipitation and estimations of the organic nitrogen mineralization rate.

AB Knowledge of the behavior and movement patterns of European starlings (Sturnus vulgaris L.) is important to wildlife managers that seek to resolve conflicts at livestock facilities. We captured and radio tagged 10 starlings at each of 5 dairies in northeastern Ohio. From September 19 to October 31, 2007, we obtained sufficient data from 40 birds to study their behavior and movements. The birds visited the dairies where they were initially captured (home sites) on 85% of the days, spending 58% of each day at the dairies. Onsite arrival and departure times were 2.5 h after sunrise and 3.1 h before sunset. Daily visits by radio-tagged cohorts from the other dairies were greatest for the 2 most proximate dairies (1.3 km apart), with number of visits between this pairing >7x that of the 9 other pairings combined (4.1-6.5 km apart). Two birds used their home sites intermittently as roosts, arriving 3.8 h before sunset and departing 0.2 h after sunrise. In addition to using home-site roosts, these birds also used a distant roost (22 km) that was used by 36 of the 40 birds. The efficacy of starling management programs, especially lethal management, depends on degree of site fidelity, use of other facilities, and roosting behavior. For example, starlings that use dairies as roosting sites may require a different management strategy than required at dairies used as daytime sites because of differences in arrival and departure behavior. Our research will help resource managers evaluate current management strategies already in place and change them, if needed, to fit the behavior profile of starlings using dairies and other types of livestock facilities.

AB China's vegetable production has experienced a rapid growth in recent years. Total production amounted to 522.7 million Mg (1 Mg = 10(6) g) in 2009, which was more than nine times that in 1980 and represented >50% of the world production. Meanwhile, excessive use of animal manures and chemical fertilizers in vegetable fields has brought various production and environmental challenges, including excessive accumulation of nutrients in soils and accelerated water pollution problems. In this study, we have evaluated the current status of phosphorus (P) in China's intensive vegetable production systems based on data summarized from nearly 100 publications plus results from our recent experiments. Gross overfertilization occurred in greenhouse (571 kg P ha(-1)) and open-field (117 kg P ha(-1)) vegetable systems compared with P removal in harvested crops (44 and 25 kg P ha(-1)) per season. Excess P input led to soil enrichment of labile P, measured as Olsen-P, averaging 179 (greenhouses) and 100 mg P kg(-1) (open fields) in the 0- to 20-cm soil depth, and in some cases led to P leaching, as evidenced by increases in Olsen-P and CaCl2 - P at the 40- to 60-cm soil depth. The vast majority of vegetable soils had Olsen-P exceeding the critical level (46.0-58.0 mg P kg(-1)) for optimum vegetable yield. Innovative policies and strategies are urgently needed to implement science-based nutrient management practices to attain sustainable vegetable production while protecting natural and environmental resources.

RICE; PADDY SOIL; GAS FLUXES; FIELDS; TRANSPORT; PLANTS; CHAMBER
AB Rice (Oryza sativa L.) production is unique among staple food crops because the majority of the growing season typically occurs under flooded-soil conditions. Flooding the soil leads to anaerobic conditions, which are a precursor to methane (CH4) production. However, no known research has investigated CH4 emissions from the drill-seeded, delayed-flood rice production system common in Arkansas, the leading rice-producing state in the United States. Therefore, research was conducted in 2011 to determine the effects of vegetation (rice and bare soil), chamber location (in-and between-rice rows), and nitrogen (N) fertilization (optimal and no N) on CH4 emissions from a silt-loam soil. Methane fluxes measured weekly from flooding until flood release were affected by vegetation, chamber location, and sample date (P < 0.05). In-row CH4 fluxes were < 0.7 mg CH4-C m(-2) h(-1) until 20 d after flooding (DAF) and < 1.0 mg CH4-C m(-2) h(-1) from between-row and bare soil until 41 DAF and were unaffected by fertilization over time. The largest weekly measured CH4 flux (31.9 mg CH4-C m(-2) h(-1)) was observed from in-row rice at 41 DAF. Post-flood-release CH4 fluxes were affected by vegetation, fertilization, chamber placement, and sample date (P < 0.05) and accounted for approximately 3 to 7% of the season-long CH4 emissions. Methane emissions averaged 195 kg CH4-C ha(-1) per growing season and were unaffected by fertilization. Direct measurement of CH4 emissions from drillseeded, delayed-flood rice grown on a silt-loam soil will improve the accuracy of assessments of the carbon footprint and long-term sustainability of rice.

AB Models are often used to predict phosphorus (P) loss from agricultural fields. Although it is commonly recognized that model predictions are inherently uncertain, few studies have addressed prediction uncertainties using P loss models. In this study we assessed the effect of model input error on predictions of annual P loss by the Annual P Loss Estimator (APLE) model. Our objectives were (i) to conduct a sensitivity analyses for all APLE input variables to determine which variables the model is most sensitive to, (ii) to determine whether the relatively easy-to-implement first-order approximation (FOA) method provides accurate estimates of model prediction uncertainties by comparing results with the more accurate Monte Carlo simulation (MCS) method, and (iii) to evaluate the performance of the APLE model against measured P loss data when uncertainties in model predictions and measured data are included. Our results showed that for low to moderate uncertainties in APLE input variables, the FOA method yields reasonable estimates of model prediction uncertainties, although for cases where manure solid content is between 14 and 17%, the FOA method may not be as accurate as the MCS method due to a discontinuity in the manure P loss component of APLE at a manure solid content of 15%. The estimated uncertainties in APLE predictions based on assumed errors in the input variables ranged from +/- 2 to 64% of the predicted value. Results from this study highlight the importance of including reasonable estimates of model uncertainty when using models to predict P loss.

AB In this study, the fate of steroid hormones in beef cattle manure composting is evaluated. The fate of 16 steroids and metabolites was evaluated in composted manure from beef cattle administered growth promotants and from beef cattle with no steroid hormone implants. The fate of estrogens (primary detected as estrone), androgens, progesterone, and the fusarium metabolite and implant a-zearalanol was monitored in manure compost piles. First-order decay rates were calculated for steroid half-lives in compost and ranged from 8 d for androsterone to 69 d for 4-androstenedione. Other steroid concentration data could not be fit to first-order decay models, which may indicate that microbial processes may result in steroid production or synthesis in composting systems. We demonstrate that composting is an effective strategy to remove steroid hormones from manure. Total steroid hormone removal in composted beef cattle manure ranged from 79 to 87%.

TI Introducing the GRACEnet/REAP Data Contribution, Discovery, and
Retrieval System
SO JOURNAL OF ENVIRONMENTAL QUALITY
LA English
DT Article
AB Difficulties in accessing high-quality data on trace gas fluxes and performance of bioenergy/bioproduct feedstocks limit the ability of researchers and others to address environmental impacts of agriculture and the potential to produce feedstocks. To address those needs, the GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) and REAP (Renewable Energy Assessment Project) research programs were initiated by the USDA Agricultural Research Service (ARS). A major product of these programs is the creation of a database with greenhouse gas fluxes, soil carbon stocks, biomass yield, nutrient, and energy characteristics, and input data for modeling cropped and grazed systems. The data include site descriptors (e.g., weather, soil class, spatial attributes), experimental design (e.g., factors manipulated, measurements performed, plot layouts), management information (e.g., planting and harvesting schedules, fertilizer types and amounts, biomass harvested, grazing intensity), and measurements (e.g., soil C and N stocks, plant biomass amount and chemical composition). To promote standardization of data and ensure that experiments were fully described, sampling protocols and a spreadsheet-based data-entry template were developed. Data were first uploaded to a temporary database for checking and then were uploaded to the central database. A Web-accessible application allows for registered users to query and download data including measurement protocols. Separate portals have been provided for each project (GRACEnet and REAP) at nrrc.ars.usda.gov/slgracenet/#/Home and nrrc.ars.usda.gov/slreap/#/Home. The database architecture and data entry template have proven flexible and robust for describing a wide range of field experiments and thus appear suitable for other natural resource research projects.

TI Rac1 mediates cytokine-stimulated hemocyte spreading via prostaglandin

AB Cell spreading is an integral component of insect hemocytic immune reactions to infections and invasions. Cell spreading is accomplished by cytoskeleton rearrangement, which is activated by three major immune mediators, biogenic monoamines, plasmatocyte-spreading peptide (PSP), and eicosanoids, particularly prostaglandin E-2 (PGE(2)). However, little is known about how these immune mediators activate hemocyte spreading at the intra-cellular level. A small G protein, Rac1, acts in cytoskeleton arrangements in mammalian cells. Based on this information, we identified a Rac1 transcript (SeRac1) in hemocytes prepared from Spodoptera exigua. SeRac1 was expressed in most developmental stages and in the two main immunity-conferring tissues, hemocytes and fat body, in larvae. In response to bacterial challenge, its expression was up-regulated by >37-fold at 2 h post-injection and returned to a basal level about 2 h later. Silencing SeRac1 expression inhibited hemocyte spreading in response to three immune mediators, octopamine, 5-hydroxytryptamine, and PSP. Addition of PGE(2) to SeRac1-silenced larvae rescued the influence of these three mediators on hemocyte spreading. These compounds also increased phospholipase A(2) activity via SeRac1, which leads to prostaglandin biosynthesis. We infer that SeRac1 transduces OA, 5-HT, and PSP signaling via activating biosynthesis of prostaglandins and possibly other eicosanoids. (C) 2013 Elsevier Ltd. All rights reserved.

AB Our objectives were to determine if porcine serum could be enriched with selenium (Se) by feeding pigs with high concentrations of dietary Se and if the Se-biofortified serum inhibited proliferation of 3 types of human cancer cells. In Expt. 1, growing pigs (8 wk old, n = 3) were fed 0.02 or 3.0 mg Se/kg (as sodium selenite) for 16 wk and produced serum with 0.5 and 5.4 mu mol/L Se, respectively. In Expt. 2, growing pigs (5 wk old, n = 6) were fed 0.3 or 1.0 mg Se/kg (as Se-enriched yeast) for 6 wk and produced serum with 2.6 and 6.2 mu mol/L Se, respectively. After the Se-biofortified porcine sera were added at 16% in RPMI 1640 to treat NCI-H446, DU145, and HTC116 cells for 144 h, they decreased (P < 0.05) the viability of the 3 types of human cancer cells by promoting apoptosis, compared with their controls. This effect was replicated only by adding the appropriate amount of methylseleninic acid to the control serum and was mediated by a downregulation of 8 cell cycle arrest genes and an upregulation of 7 apoptotic genes. Along with 6 previously reported selenoprotein genes, selenoprotein T (Selt), selenoprotein M (Selm), selenoprotein H (Selh), selenoprotein K (Selk), and selenoprotein N (Sepn1) were revealed to be strongly associated with the cell death-related signaling induced by the Se-enriched porcine serum. In conclusion, porcine serum could be biofortified with Se to effectively inhibit the proliferation of 3 types of human cancer cells and the action synchronized with a matrix of coordinated functional expression of multiple selenoprotein genes.

AB There is increased interest in winter canola as an oilseeds crop for production of oil or biodiesel in the southeastern United States, but research has been limited. The objective of this study was to evaluate the effect of N (0, 60, 120, 180 kg N ha(-1)) on productivity, oil content and oil composition of winter canola grown for two cropping seasons at three locations in Mississippi (Stoneville, and two locations at Verona: Verona upland silt loam, Verona-SL and Verona upland clay, Verona-C). Overall, increasing N application rates resulted in corresponding stepwise increase in seed yields in the two locations at Verona, whereas yields in the 60 and 120 kg N ha(-1) at Stoneville were not different from each other. Seed yields reached 3,383 and 3,166 kg ha(-4) in the 180 kg N treatment at Verona and at Stoneville, respectively. Oil yields were also increased with increasing N rates, however, oil yields at 60 and 120 kg N ha(-4) at Verona-C were not different from each other. Oil yields in the 180 kg N ha(-1) treatment reached 1,363 and 1,151 kg ha(-1) at Verona-SL and Stoneville, respectively. At Verona-SL location, higher N rates resulted in increased stearic acid compared to the lower N rates. However, the reverse effect was observed on the concentration of linolenic acid, which was lower at higher N rates. Also at that location, N application reduced the concentration of linoleic acid. At the Verona-C location, N application at 180 kg N ha(-1) reduced concentration of linolenic acid relative to the other fertility treatments. Overall, the increase in N application rates resulted in greater yield (kg FA ha(-1)) of palmitic, palmitoleic, stearic, oleic, linoleic, linolenic, arachidic, eicosanoic, behenic, lignoceric and nervonic acids in all three locations, with N at 0 kg ha(-1) providing the lowest yields and N at 180 kg ha(-1) providing the highest yields. Winter canola production in the hot humid environment of southeastern United States can be successful and could provide seed and oil yields comparable to yields from major winter canola production areas.

AB External morphological criteria that enable the rapid determination of gender have been developed for Yellow Perch Perca flavescens. Criteria are based upon (1) shape of the urogenital papilla (UGP), (2) size of the UGP relative to the anal (AN) opening, and (3) coloration of the UGP. In females, the UGP appeared (1) rounded at the anterior margin, (2) pointed at the posterior margin and had a V or U shape (crescent shaped in mature animals), (3) generally lacked reddish coloration, and (4) narrower relative to the AN. In males, the UGP (1) appeared circular or oval around the entire margin, (2) typically displayed reddish coloration, and (3) was generally wider relative to the AN. To verify accuracy of these criteria, gender was verified internally in perch of various sizes, sex, and maturity from four domesticated geographic strains (n = 1,389). For all perch tested, accuracy was 97.3% for both sexes, 98.8% for females, and 95.9% for males. To experimentally verify accuracy of these criteria, juvenile Yellow Perch (n = 913) were treated with dietary 17-estradiol (E2; 15mg/kg diet) or a control diet. Accuracy was 97.7% for control females and 95.1% for control males, which diminished to 63.9% for the E2-treated females and 57.6% for E2-treated males. We developed a gender identification algorithm that will enable sorting of sexes for many uses including (1) collection of broodstock by new aquaculture producers, (2) management of broodstocks for existing producers, (3) improved selection criteria for genetic selection programs, (4) studies on gender-specific differences in Yellow Perch physiology, and (5) the unharmed release of fish in field and aquaculture settings. Uncoupling of external UGP morphology from actual gender in E2-treated perch can enable producers and biologists to detect exposure to estrogenic compounds in areas where endocrine disruption is suspected.

AB Studies have shown an association between nut consumption and health benefits in adults such as lower lipid levels, lowerbody mass indices, and reduced risk of coronary artery disease. Few studies have demonstrated these health benefits in children. To determine the association between peanut consumption and weight, intake of nutrients of concern, high-density lipoprotein, low-density lipoprotein, and cholesterol in Mexican American children, baseline data from 262 sixth-grade students (48% female) in a school-based weight management program were analyzed to compare differences between peanut and non-peanut eaters. It was hypothesized that Mexican American children who consume peanuts will be less overweight and have a better nutrient and lipid profile when compared to those who do not eat peanuts. Participants completed a food frequency questionnaire as a baseline dietary assessment before beginning the program. Children were identified as either a peanut consumer (n = 100) or non-peanut consumer (n = 162). Body mass index measurements were taken on all participants. A smaller sample of participants submitted blood for lipid analysis. Analyses revealed that children in the peanut consumer group were less likely to be overweight or obese than children in the non-peanut consumer group (x(2)= 13.9, P =.001), had significantly higher intakes of several vitamins and micronutrients (i.e., magnesium, vitamin E), and had lower low-density lipoprotein and total cholesterol levels. These results illustrate that consumption of peanuts and/or peanut butter is associated with lower weight status, improved diet, and lipid levels among Mexican American children. Future research is needed to clarify the role of peanut consumption in children's overall health. (C) 2013 Elsevier Inc. All rights reserved.

AB The insulin-like growth factor pathway plays a central role in the normal and abnormal growth of tissues; however, nutritional determinants of insulin-like growth factor I (IGF-I) and its binding proteins in healthy individuals are not well defined. Three test diets-high-fat diet (40% energy as fat), low-fat diet (LF; 20% energy as fat), and a diet with low fat and high omega-3 fatty acid (LFn3; 23% energy as fat)-were tested in a randomized crossover designed controlled feeding trial in healthy postmenopausal women. Plasma IGF-I, IGF binding protein-3 (IGFBP-3), insulin, glucose, and ratio of IGF-I/IGFBP-3 concentrations were measured in response to diets. Insulin sensitivity was calculated using the homeostatic model assessment of insulin resistance We hypothesized that IGF-I, insulin, and glucose concentrations would decrease and IGFBP-3 concentration would increase in response to the low-fat diets. Eight weeks of the LFn3 diet increased circulating IGF-I (P <.001) and IGFBP-3 (P =.01) and the LF diet increased IGFBP-3 (P =.04), resulting in trends toward an increased IGF-I/IGFBP-3 ratio with the LFn3 diet and a decreased IGF-I/IGFBP-3 ratio with the LF diet (P =.13 for both comparisons). No statistically significant differences were detected between treatments at baseline or 8 weeks for IGF-1, IGFBP-3, or the ratio of IGF-1/IGFBP-3. Insulin, glucose, and the homeostatic model assessment of insulin resistance were not altered by the interventions. Low-fat diet with high n-3 fatty acids may increase circulating IGF-I concentrations without adversely affecting insulin sensitivity in healthy individuals. Published by Elsevier Inc.

AB Salinity is one of the major abiotic factors affecting alfalfa productivity. Identifying genes that control this complex trait will provide critical insights for alfalfa breeding programs. To date, no studies have been published on a deep sequencing-based profiling of the alfalfa transcriptome in response to salinity stress. Observations gathered through research on reference genomes may not always be applicable to alfalfa. In this work, Illumina RNA-sequencing was performed in two alfalfa genotypes contrasting in salt tolerance, in order to estimate a broad spectrum of genes affected by salt stress. A total of 367,619,586 short reads were generated from cDNA libraries originated from roots of both lines. More than 60,000 tentative consensus sequences (TCs) were obtained and, among them, 74.5% had a significant similarity to proteins in the NCBI database. Mining of simple sequence repeats (SSRs) from all TCs revealed 6,496 SSRs belonging to 3,183 annotated unigenes. Bioinformatics analysis showed that the expression of 1,165 genes, including 86 transcription factors (TFs), was significantly altered under salt stress. About 40% of differentially expressed genes were assigned to known gene ontology (GO) categories using Arabidopsis GO. A random check of differentially expressed genes by quantitative real-time PCR confirmed the bioinformatic analysis of the RNA-seq data. A number of salt-responsive genes in both tested genotypes were identified and assigned to functional classes, and gene candidates with roles in the adaptation to salinity were proposed. Alfalfa-specific data on salt-responsive genes obtained in this work will be useful in understanding the molecular mechanisms of salinity tolerance in alfalfa.

AB The plant hormone ethylene is known to affect various developmental processes including dormancy and growth. Yet, little information is available about the role of ethylene during paradormancy release in underground adventitious buds of leafy spurge. In this study, we examined changes in ethylene evolution and the ethylene biosynthetic enzyme ACC oxidase following paradormancy release (growth induction). Our results did not show an obvious increase in ethylene during bud growth. However, when buds were incubated with 1 mM ACC, ethylene levels were higher in growing than non-growing buds, suggesting that the levels of ACC oxidase increased in growing buds. Real-time qPCR indicated that the transcript of a Euphorbia esula ACC oxidase (Ee-ACO) increased up to threefold following growth induction. In addition, a 2.5- to 4-fold increase in ACO activity was observed 4 days after decapitation, and the Ee-ACO accounted for 40 % of the total ACO activity. Immunoblot analyses identified a 36-kD Ee-ACO protein that increased in expression during bud growth. This protein was highly expressed in leaves, moderately expressed in crown buds, stems and meristems, and weakly expressed in roots and flowers. Immunolocalization of Ee-ACO on growing bud sections revealed strong labeling of the nucleus and cytoplasm in cells at the shoot apical meristem and leaf primordia. An exception to this pattern occurred in cells undergoing mitosis, where labeling of Ee-ACO was negligible. Taken together, our results indicated an increase in the levels of Ee-ACO during paradormancy release of leafy spurge that was not correlated with an increase in ethylene synthesis.

AB Anthocyanin gene expression has been extensively studied in leaves, fruits and flowers of numerous plants. Little, however, is known about anthocyanin accumulation in roots of carrots or other species. We quantified expression of six anthocyanin biosynthetic genes [phenylalanine ammonia-lyase (PAL3), chalcone synthase (CHS1), flavanone 3-hydroxylase (F3H), dihydroflavonol 4-reductase (DFR1), leucoanthocyanidin dioxygenase (LDOX2), and UDP-glucose:flavonoid 3-O-glucosyltransferase (UFGT)] in three carrot inbreds with contrasting root color: solid purple (phloem and xylem); purple outer phloem/orange xylem; and orange phloem and xylem. Transcripts for five of these genes (CHS1, DFR1, F3H, LDOX2, PAL3) accumulated at high levels in solid purple carrots, less in purple-orange carrot, and low or no transcript in orange carrots. Gene expression coincided with anthocyanin accumulation. In contrast, UFGT expression was comparable in purple and orange carrots and relatively unchanged during root development. In addition, five anthocyanin biosynthesis genes [FLS1 (flavonol synthase), F3H, LDOX2, PAL3, and UFGT] and three anthocyanin transcription factors (DcEFR1, DcMYB3 and DcMYB5) were mapped in a population segregating for the P (1) locus that conditions purple root color. P (1) mapped to chromosome 3 and of the eight anthocyanin biosynthesis genes, only F3H and FLS1 were linked to P (1). The gene expression and mapping data suggest a coordinated regulatory control of anthocyanin expression in carrot root and establish a framework for studying the anthocyanin pathway in carrots, and they also suggest that none of the genes evaluated is a candidate for P (1).

AB Little is known of the genetic diversity of Toxoplasma gondii circulating in wildlife. In the present study, antibodies to T. gondii were determined in serum samples from 632 mute swans (Cygnus olor) collected from different areas of the USA. Sera were tested by T. gondii modified agglutination test; 54 (8.5%) of 632 samples were seropositive with titers of 25 in 28 sera, 50 in 22 sera, 100 in three samples, and 200 or higher in one swan. Hearts from 14 seropositive swans were bioassayed in mice and viable T. gondii (designated TgSwanUs1-3) were isolated from the hearts of three. These three T. gondii isolates were further propagated in cell culture, and DNA isolated from culture-derived tachyzoites was characterized using 11 PCR-RFLP markers (SAG1, 5'- and 3'-SAG2, alt.SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1 and Apico). Results of genotyping revealed that two strains (TgSwanUs1, TgSwanUs2) were Type III (ToxoDB PCR-RFLP genotype #2), and TgSwanUs3 was a new genotype designated here as ToxoDB PCR-RFLP genotype #216. Pathogenicity of oocysts derived from these three strains was determined in Swiss Webster (SW) outbred mice. All mice infected with oocysts and tachyzoites of the atypical isolate (TgSwanUs3) died of acute toxoplasmosis, irrespective of the dose. Oocysts of the remaining two isolates were. less pathogenic but differed from each other; 10 oocysts of the TgSwanUs1 killed all inoculated mice whereas 1 million oocysts of the TgSwanUs2 were needed to kill all infected SW mice. Isolation of T. gondii from mute swan indicates that the local waters were contaminated by T. gondii oocysts, and that mouse T. gondii virulent strains are circulating in wildlife. Mute swan is a new host record for T. gondii. Published by Elsevier B.V.

AB A tall waterhemp population from Missisippi was suspected to be resistant to glyphosate. Glyphosate dose response experiments resulted in GR(50) (dose required to reduce plant growth by 50%) values of 1.28 and 0.28 kg ae ha(-1) glyphosate for the glyphosate-resistant (GR) and -susceptible (GS) populations, respectively, indicating a five-fold resistance. The absorption pattern of C-14-glyphosate between the GR and GS populations was similar up to 24 h after treatment (HAT). Thereafter, the susceptible population absorbed more glyphosate (55 and 49% of applied) compared to the resistant population (41 and 40% of applied) by 48 and 72 HAT, respectively. Treatment of a single leaf in individual plants with glyphosate at 0.84 kg ha(-1), in the form of 10 1-mu l droplets, provided greater control (85 vs. 29%) and shoot fresh weight reduction (73 vs. 34% of nontreated control) of the GS plants compared to the GR plants, possibly indicating a reduced movement of glyphosate in the GR plants. The amount of C-14-glyphosate that translocated out of the treated leaves of GR plants (20% of absorbed at 24 HAT and 23% of absorbed at 48 HAT) was significantly lower than the GS plants (31% of absorbed at 24 HAT and 32% of absorbed at 48 HAT). A potential difference in shikimate accumulation between GR and GS populations at different concentrations of glyphosate was also studied in vitro. The IC50 (glyphosate concentration required to cause shikimate accumulation at 50% of peak levels measured) values for the GR and GS populations were 480 and 140 mu M of glyphosate, respectively, resulting in more shikimate accumulation in the GS than the GR population. Sequence analysis of 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), the target site of glyphosate, from GR and GS plants identified a consistent single nucleotide polymorphism (T/C, thymine/cytosine) between GR/GS plants, resulting in a proline to serine amino acid substitution at position 106 in the GR population. The GR and GS plants contained equal genomic copy number of EPSPS, which was positively correlated with EPSPS gene expression. Thus, glyphosate resistance in the tall waterhemp population from Mississippi is due to both altered target site and nontarget site mechanisms. This is the first report of an altered EPSPS-based resistance in a dicot weed species that has evolved resistance to glyphosate.

AB Robust predictions of weed seedling emergence from the soil seedbank are needed to aid weed management. A common seed accession (Illinois) of giant ragweed was buried in replicate experimental gardens over 18 site years in Illinois, Michigan, Kansas, Nebraska, Ohio, and South Dakota to examine the importance of site and climate variability by year on seedling emergence. In a nonlinear mixed-effects modeling approach, we used a flexible sigmoidal function (Weibull) to model giant ragweed cumulative seedling emergence in relation to hydrothermal time accumulated in each site-year. An iterative search method across a range of base temperature (T-b) and base and ceiling soil matric potentials (psi(b) and psi(c)) for accumulation of hydrothermal time identified optima (T-b = 4.4 C, psi(b) = 2,500 kPa, psi(c) = 0 kPa) that resulted in a parsimonious regional model. Deviations between the fits for individual site-years and the fixed effects regional model were characterized by a negative relationship between random effects for the shape parameter lrc (natural log of the rate constant, indicating the speed at which emergence progressed) and thermal time (base 10 C) during the seed burial period October through March (r = -0.51, P = 0.03). One possible implication of this result is that cold winter temperatures are required to break dormancy in giant ragweed seeds. By taking advantage of advances in statistical computing approaches, development of robust regional models now is possible for explaining arable weed seedling emergence progress across wide regions.

AB Infection by Xanthomonas axonopodis pv. manihotis (Xam) of the perennial rangeland weed leafy spurge was tested to see whether Xam might serve a potential biological control agent for this invasive weed. Although leafy spurge was susceptible to Xam infection, it recovered within 21 d after inoculation (DAI). Microarray resources available for leafy spurge allowed us to follow the physiological and signaling pathways that were altered as leafy spurge was infected and then recovered from Xam infection. The first physiological effect of Xam infection was a down-regulation of photosynthetic processes within 1 DAI. By 7 DAI, numerous processes associated with well-documented pathogenesis responses of plants were observed. Although some pathogenesis responses were still detectable at 21 DAI, other processes associated with meristem development were noted. Ontological analysis of potential signaling systems indicated jasmonic acid plays a significant role in the recovery processes.

AB Sweet corn is seeded under a wide range of population densities; however, the extent to which variable population density influences weed suppression is unknown. Therefore, field studies were undertaken to quantify the influence of sweet corn seeding level on growth, seed production, and post-harvest seed germination of wild-proso millet, one of the most problematic weeds in the crop. As crop seeding level increased, path analysis results indicated the crop canopy became taller and thicker, resulting in less wild-proso millet biomass, seed production, and germinability. However, at the level of individual fields, reductions in wild-proso millet growth and seed production were modest, at best, between a crop population currently used by growers and a higher crop population known to optimize yield of certain hybrids. These results indicate near-future increases in sweet corn seeding levels may play a minor role in improving weed management in individual sweet corn fields. Nonetheless, a reduction in crop populations, via weather- or management-driven phenomenon, increases risk of greater wild-proso millet seed production.

AB Bermudagrass is a difficult perennial weed to manage in Louisiana sugarcane. Research was conducted to compare interrow tillage practice, postharvest residue management, and herbicide placement on bermudagrass proliferation and sugarcane yield. Tillage frequencies included conventional (four tillage operations per season), reduced (two tillage operations), and no-till. Residue management practices included removal by burning, sweeping from row top into the wheel furrow, and not removed. Spring herbicide placement treatments included broadcast, banded, or no herbicide application. With conventional tillage, broadcast and banded herbicide applications resulted in similar bermudagrass cover in the First and second ratoon crops, but bermudagrass cover was greater when using banded applications (22%) compared with broadcast application (15%) in the third-ratoon crop. Bermudagrass cover was greatest with no-till. When herbicides were banded, bermudagrass cover was greater in reduced tillage than conventional tillage in all three ratoon crops. Postharvest residue management did not affect bermudagrass ground cover. In plant cane, sugarcane yields were lowest when herbicide was not applied. In ratoon crops, sugarcane and sugar yield were reduced when herbicide was not applied regardless of tillage practice. Cane and sugar yield were generally equal when comparing reduced and conventional tillage. Total sugarcane yield (4 crop yr) for the no-till program was reduced 11, 15, and 25%, respectively, when herbicides were broadcast, banded, and when herbicide was not applied, compared with conventional tillage. Failure to remove residue reduced sugarcane yield by 5, 7, and 10% in first, second, and third ratoons, respectively, compared with burning. Eliminating unnecessary tillage practices can increase profitability of sugarcane through reduced costs, but it will be imperative that herbicide programs be included to provide adequate bermudagrass control and that postharvest residue is removed to promote maximum sugarpostane yield.

AB Estimates of large dead and down woody material biomass are used for evaluating ecological processes and making ecological assessments, such as for nutrient cycling, wildlife habitat, fire effects, and climate change science. Many methods are used to assess the abundance (volume) of woody material, which ultimately require an estimate of wood density to convert volume to biomass. To assess wood density and decomposition rate, this study examined in situ wood density of lodgepole pine logs at the Tenderfoot Creek Experimental Forest, central Montana, 1 and 11 years after felling. Wood density decreased from 0.39 g cm(-3) to 0.35 g cm(-3) over 10 years and the single exponential decay rate was 0.0085 yr(-1). A common 5-category decay classification system was evaluated for estimating wood density by decay class; however, the relationship was only partially significant.

AB In recent years, interest has increased in silvicultural systems and harvest cuts that retain partial overstories, but there are few data available on the growth of the understory trees in such stands. We studied the response of overstory trees and underplanted seedlings, Douglas-fir (Pseudotsuga menziesii), western hemlock (Tsuga heterophylla), and western redcedar (Thuja plicata), to a range of residual overstory densities. Forty to 70-year-old Douglas-fir stands in western Washington were harvested, leaving retention levels of 0, 8, 16, 24, 32, and 40% of full stocking. The 9-year response of the understory seedlings was species-dependent with Douglas-fir the largest in diameter (mean diameter 6.4 cm and mean height 3.8 m), western hemlock the tallest (mean diameter 5.5 cm and mean height 5.4 m), and redcedar the smallest (mean diameter 1.5 cm and mean height 1.5 m), in part because it was heavily browsed. Douglas-fir and western redcedar showed the greatest growth in the lowest retention levels (0 and 8%), and western hemlock responded best at the middle retention levels (8 and 16%).

ID FORESTS; SEASON; MORTALITY; RESPONSES; SEVERITY; ARIZONA; BURN
AB Prescribed burning is used to reduce fuel loads and to return fire to its historic disturbance role in western forests. Managers need to know the effects of prescribed fire on tree growth. Growth of residual ponderosa pine (Pinus ponderosa Dougl. ex Laws.) was measured in an existing long-term study of the effects of season-of-prescribed burn in combination with a single or a repeated burn. Each of six previously thinned mixed-age stands in the Blue Mountains near Burns, Oregon, was subdivided into three experimental units, and one of three treatments was randomly assigned to each: fall 1997 burn, spring 1998 burn, and no burn (control). Treatments were operational-sized prescribed burns. In 2002/2003 each burned unit was split, and one-half was burned again, maintaining the original season of burn. Sample trees were evaluated for growth 5 and 10 seasons after the initial prescribed fires. We conclude that after accounting for the crown scorch proportion neither a single spring or fall prescribed fire treatment nor a repeated fire treatment 5 years later affected the growth of thinned ponderosa pine 10 years after the initial 1997/1998 fires. A linear regression is included to estimate bark thickness based on dbh.

AB The present study assessed the personal protection efficiency of seven commercially available mosquito control devices (MCD) under field conditions in Israel. Trials were performed in a high biting-pressure area inhabited by large populations of mosquito and biting midge species, using human volunteers as bait in landing catch experiments. Results show that under minimal air-movement, three spatial repellent based products (ThermaCELL (R) Patio Lantern, OFFI (R) PowerPad lamp, and Terminix (R) ALLCLEAR Tabletop Mosquito Repeller) significantly reduced the biting-pressure (t-test - P < 0.01) when positioned at short distances from a volunteer (3, 7.5, and 10 ft.), with the ThermaCELL unit being most effective (96.1, 89.9, and 76.66% reduction, respectively). No significant differences were seen between the three aforementioned devices at distances of 3 and 7.5 ft., while at a distance of 10 ft., only the ThermaCELL patio lantern repelled significantly more mosquitoes then the Terminix ALLCLEAR Tabletop Mosquito Repeller (t-test, P < 0.05). In contrast, mosquito traps using attracting cues to bait mosquitoes (Dynatrap (R), Vortex (R) Electronic Insect Trap, Blue Rhino SV3100) either significantly increased or had no effect on the biting-pressure at short distances compared with the unprotected control. Trials conducted over large areas showed that only the Blue Rhino trap was able to significantly reduce the biting-pressure (40.1% reduction), but this was only when operating four units at the corners of an intermediate sized area.

AB Freshwater playas, shallow ephemeral lakes whose basins fill aft er periods of prolonged or intense rainfall, occupy 3 to 5% of the land in the Llano Estacado and are considered marginal farmlands. The goals of this work were to determine if a native species, eastern gamagrass, could be grown on playa soils and to preliminarily evaluate the suitability of gamagrass [Tripsacum dactyloides (L.) L.] as a component of an in situ precipitation catchment forage production system. Flooding tolerance of gamagrass seeds was evaluated, and plants were grown on playa soil in both the greenhouse and field for several seasons. Gamagrass seed was resistant to extended flooding, especially at low ambient temperatures typically encountered in late fall or winter. Gamagrass roots penetrated nearly 2 m into waterlogged playa soil in greenhouse experiments. Stands were successfully established in playas, and plants survived for 6 yr when crowns were not destroyed by close mowing or vehicles.

TI Biomass Production and Quality of Indian-Origin Forage Guar in Southern
Great Plains
SO AGRONOMY JOURNAL
LA English
DT Article
ID WARM-SEASON LEGUMES; CAPABILITIES; YIELD; CROP
AB Guar [Cyamopsis tetragonoloba (L.) Taub.] is a summer annual pulse grown in semiarid regions of the world as a multi-purpose vegetable, grain, cover, or fodder crop. Existing guar cultivars used in the U. S. southern Great Plains (SGP) were developed for grain production, and there are currently no forage cultivars available for the region. This study compared biomass production and nutritive values of plant products of three cultivars of Indian origin, forage-type guar with a commonly used grain cultivar (Kinman) to determine whether the Indian-origin cultivars would be better production options for the SGP. Aboveground biomass was sampled at early and late vegetative stages, and physiological maturity. Samples collected at maturity were separated into grain, pods, and vegetative biomass. Nitrogen and in vitro digestible dry matter (IVDDM) concentrations were determined on all biomass components. Data were analyzed using mixed models with guar cultivars and growth stage as main effects, and years as a longitudinal (repeated) element. The Indian-origin cultivars produced significantly (P < 0.05) more forage (13-22%) and less grain (26-36%) than Kinman. Growing season and time of season main effects on biomass production, N, and IVDDM concentrations of forage, pods, and grain were significant. Drier growing seasons produced 50 and 34% less forage and grain, respectively, that contained 26 and 16% more N, with 14 and 6% greater IVDDM. Results indicated additional genetic selection is required to identify productive and reliable forage-type guar cultivars that are better suited to the variable growing conditions of the SGP.

AB Sorption of plant nutrients from dairy storage lagoons by biochar and use as a supplemental fertilizer is a beneficial strategy to reduce nutrient contamination around dairies and supply nutrients to potato (Solanum tuberosum L.) and other crops. This research evaluated potato growth responses and P partitioning from several rates of P applied as either mono-ammonium phosphate (MAP) or as P recovered from anaerobic digested dairy manure using biochar. Single-stemmed plants of the potato cultivars Ranger Russet and Umatilla Russet were grown in 7-L pots containing Quincy sand soil (mixed, mesic Xeric Torripsamment). Biochar amended with dairy effluent applied at 5.7 and 11.4 Mg ha(-1) with fertilizer application rates equivalent to 55 and 110 kg P ha(-1) maintained adequate P levels in potato petioles of both cultivars through 85 d after planting. Total plant P uptake was greater for treatments receiving MAP. Total potato biomass and tuber yields of Umatilla Russet were 30 and 27% lower when amended with basic or enriched biochar compared to MAP treatments, respectively. Tuber biomass declined 10 and 20% for Ranger Russet and Umatilla Russet for the 11.4 Mg ha(-1) amended biochar, respectively compared to MAP fertilized treatments. Similar declines were found for the aboveground biomass and roots. The 5.7 Mg ha(-1) of enriched biochar supplied 70 to 80% of the P requirement for potato growth. These findings are an important step in providing evidence of the benefits of using recovered P as a fertilizer supplement to reduce the reliance on rock phosphates.

TI Photoperiod and Vernalization Effect on Anthesis Date in Winter-Sown
Spring Wheat Regions
SO AGRONOMY JOURNAL
LA English
DT Article
ID MODELS; SIMULATION
AB Accurate prediction of phenology is required to guide crop management decisions and to predict crop growth and yield. However, the relative importance of photoperiod and vernalization in predicting anthesis dates for spring bread and durum wheat (Triticum aestivum L. and T. durum Desf.) sown in the winter has not been reported. The purpose of this research is to determine the improvement in predicting anthesis dates of spring wheat sown in the winter when photoperiod and vernalization are considered. Observed dates of anthesis were obtained from University of Arizona wheat variety trials conducted at Maricopa, Wellton, and Yuma, AZ. The Cropping Systems Model CROPSIM-CERES as released in DSSAT 4.5 was used to simulate days to anthesis based on temperature, daylength, and vernalization. For 12 bread and durum wheat cultivars, the model predicted days to anthesis with a root mean square error (RMSE) of 7.6 d if all cultivar differences were ignored, 6.4 d considering only differences in thermal time (TT), 6.1 d with differences in TT and daylength response, 6.4 d with TT and vernalization, and 6.2 d with TT, daylength, and vernalization. Consideration of cultivar differences in TT and photoperiod response improved the prediction of days to anthesis for winter-sown spring wheat, but there was no benefit from considering effects of vernalization in CROPSIM-CERES.

AB The declining saturated thickness of the Ogallala Aquifer beneath the southern High Plains decreases irrigation well capacity and necessitates conservation of precipitation for crop use. A 3-yr dryland crop rotation of wheat (Triticum aestivum L.) followed by cotton (Gossypium hirsutum L.) with intervening 10-mo fallow periods was adapted for use with deficit irrigation of 2.5 and 5.0 mm d(-1) capacities on a Pantex silty clay loam (fine, mixed, superactive, thermic Torrertic Paleustoll) managed with disk (DT), stubble-mulch (SM), or no (NT)-tillage at Bushland, TX (35.183 degrees N, 102.1 degrees W). Study objectives were to quantify tillage effects on soil water storage during wheat fallow and any continued effects on water use and yield by deficit irrigated cotton. Compared with DT, wheat residue cover increased mean fallow precipitation storage by similar to 15 mm for SM and 50 mm with NT based on significant differences in 3 of 4 yr. The significant differences in cotton water use between irrigation capacities totaled from 70% to similar to 100% of the estimated evapotranspiration, ET. Measured growing season water use decreased with decreasing residue cover in the order NT > SM > DT. Cotton lint yield did not vary between irrigation capacities, but increased with NT by similar to 50% or 450 kg ha(-1) over DT. Yields for DT cotton irrigated at 5 mm d(-1) were typically less than for NT and SM cotton irrigated at 2.5 mm d(-1). Lint yield for NT management was significantly greater than DT, which we attributed to reduced evaporation and greater transpiration with NT residue.

AB Residue management to increase fallow precipitation storage and reduce growing season evaporation limited potential yield reduction by off setting a portion of the decreasing irrigation well capacity of the declining Ogallala Aquifer in the southern High Plains. A 3-yr dryland rotation of wheat (Triticum aestivum L.) followed by corn (Zea mays L.) with intervening 10-mo fallow periods was adapted for use with deficit irrigation of 2.5 and 5.0 mm d(-1) capacities on a Pantex silty clay loam (fine, mixed, superactive, thermic Torrertic Paleustoll) at Bushland, TX (35 degrees 11' N, 102 degrees 6' W). Study objectives were to quantify disk (DT), stubble-mulch (SM), or no (NT)-tillage effects on precipitation storage during wheat fallow and subsequent use for grain yield by deficit irrigated corn. The 4-yr mean soil water after fallow increased from 14 to 50 mm for SM and NT compared with DT. Measured growing season water use ranged from similar to 54 to 64% of the estimated corn water use (ETc) at the 2.5 mm d(-1) irrigation capacity and from 76 to 85% at 5.0 mm d(-1) irrigation with corresponding grain yields ranging from crop failure to similar to 7.4 Mg ha(-1). We conclude that residue retaining conservation tillage increased soil water storage during fallow. We attributed greater corn yield with conservation tillage to likely increased transpiration made possible by reducing early growing season evaporation. Increased soil water and greater transpiration using conservation tillage practices did not off set corn ET reduction imposed by either deficit irrigation capacity and resulted in unprofitable crop yield reductions.

TI Corn Grain and Stover Yield Prediction at R1 Growth Stage
SO AGRONOMY JOURNAL

DT Article
ID IN-SEASON PREDICTION; NITROGEN UPTAKE; PLANT HEIGHT; VARIABILITY
AB Estimating corn (Zea mays L.) grain and stover yield during the growing season is an appealing idea. An accurate yield estimation could benefit farmers, as well as corn-related industries. The objective of this study was to develop regression equations to estimate corn grain and stover yield using easily accessible information (N fertilization rate and cumulative precipitation), and simple plant morphological measurements such as height, stem diameter at various heights, height of the first ear, and plants per hectare. Measurements made at silking (R1) were used since the maximum explainable variability would not exceed 58% at early stages of plant development (V2-V10; between 2-leaf and 10-leaf stages). The experiment was conducted from 2009 until 2011 in two locations, in north and central Alabama, under no-tillage and non-irrigated conditions. Treatments were assigned to a 3 x 4 x 2 complete factorial design arranged in a split-split-plot with three replications. Factors were; winter rye (Secale cereale L.) cover crop (main plot), N fertilization rates (subplot), and stover residue harvest (sub-subplot). All measurements from this study, across years and locations, were used in the final regression equations to create robust prediction models. Equations, with and without intercept, were developed and compared according to several statistical criteria. The final grain yield equation at R1 growth stage included an intercept with a R-2 of 0.7705. The final stover equation also included an intercept (R-2 = 0.8473). This study suggests that N rate, total precipitation amount from planting until silking, and simple plant morphological measurements can be used to predict corn yield.

AB Although farmers in the midwestern United States often apply livestock manure when terminating alfalfa (Medicago sativa L.), there are no published reports on direct effects of fall manure application on alfalfa N credits to first-year corn (Zea mays L.). Therefore, eight on-farm experiments were conducted in Minnesota to test whether manure applied during alfalfa termination in fall affects the rate of fertilizer N needed for the subsequent corn crop. Manure application rates were determined by cooperating growers and N fertilizer rates were 0, 45, 90 or 179 kg N ha(-1) at planting and 45 kg N ha(-1) as a sidedress. At five locations, neither manure nor fertilizer N increased grain or silage yield. At three remaining locations, N fertilizer was needed to economically optimize grain (98 kg N ha(-1) at two locations) or silage yield (113 kg N ha(-1) at three locations), but manure did not alter the response to fertilizer N. The presidedress soil nitrate test (PSNT) predicted the need for N fertilizer to optimize grain yield 63% of the time and the basal stalk nitrate test (BSNT) identified the need for N fertilizer 75% of the time. When results of this study were combined with data from the literature, the PSNT was accurate only 55% of the time and the BSNT could not separate responsive and nonresponsive sites. These results confirm that first-year corn following alfalfa oft en does not require supplemental N for maximum grain yield, and that more accurate methods are needed to predict fertilizer N response.

AB Development of sustainable crop rotations depends on understanding complex relationships among soils, crops, and yield. Our objectives were to measure how soil chemical and physical attributes as well as soybean [Glycine max (L.) Merr.] stover dry weight and mineral concentrations, seed yield, and seed composition (protein, oil, and minerals) responded to a soybean-maize (Zea mays L.) 2-yr rotation (S-C), soybean-spring wheat (Triticum aestivum L.)maize 3-yr rotation (S-W-C), soybean-oat/pea (Hordeum vulgare L./Pisum sativum L.) hay-maize 3-yr rotation (S-H-C), and soybean-oat/pea hay underseeded with alfalfa (Medicago sativa L.)-alfalfa-alfalfa-maize 5-yr rotation (S-H/A-A-A-C). Rotation treatments under no-till soil management were established in 1997 and soybean measurements were made during the 2009 and 2010 growing seasons. Soils under the 5-yr rotation had 129 kg ha(-1) preseason residual NO3-N concentration, while the other rotations averaged about 65 kg ha(-1). The 5-yr rotation also had lower bulk density (1.35 g cm(-3)) than S-H-C (1.46 g cm(-3)), with S-W-C (1.38 g cm(-3)) and S-C (1.38 g cm(-3)) intermediate. Soybean seed yield was about 10% greater in the 5-yr rotation than in the other treatments. Kernel protein was 3% greater and kernel Zn was 11% greater under the 5-yr rotation than under the S-C rotation, while the others were intermediate. Changes in soil physical and chemical properties under extended rotations that include perennial forages may play an important role in increasing soybean seed yield and enhancing seed protein but may, because of high preseason soil NO3-N levels, also be susceptible to potential NO3-N leaching beyond the root zone.

AB Over 1100 species of oligochaetes are known from Latin America (LA), of which most are earthworms. Enchytraeid research is not so well developed, mainly due to their small size, the difficulty of identification, and the general ignorance of LA scientists of this family. Some countries, such as Brazil, Colombia and Mexico have active taxonomists, and hence tend to have better knowledge of oligochaete diversity and ecology. However, the few professionals active in the area and a major taxonomic impediment have greatly hindered research on oligochaetes in LA. Four Latin American Meetings on Oligochaete Ecology and Taxonomy (ELAETAO) have been held since 2003. These meetings brought together researchers, students and technicians from 15 countries and resulted in several landmark publications (3 special journal issues and one book) that synthesize research performed in the Americas. Topics addressed include the diversity and distribution of native and exotic earthworm species in all LA countries, the use of oligochaetes as bioindicators, oligochaete genetics and phylogeny, various aspects of vermiculture, earthworm and enchytraeid sampling methods, and ecology and biology of invasive species, among others. Furthermore, since the first ELAETAO, regular training in terrestrial oligochaete ecology and taxonomy (10 earthworm and 2 enchytraeid short courses), as well as in ecotoxicology and molecular genetics has been offered to 150 scientists and students in these topics in order to build capacity for research activity. The ELAETAOs have greatly stimulated earthworm and enchytraeid research in LA, but several challenges must still be overcome to adequately assess the true nature of oligochaete biodiversity and their ecology in the region.

AB A recent handful of studies have linked baculovirus infection with the induction of heat shock proteins, a highly conserved family of cytoprotective proteins. Here, we demonstrate baculovirus-stimulated upregulation of hsp70 transcription in the natural host, Helicoverpa zea. Larvae lethally infected with Helicoverpa zea single nucleopolyhedrovirus (HzSNPV) accumulated hsp70 transcripts throughout the 72-hour course of infection in the midgut, hemocytes, and fat body. While a maximal 17- or 15-fold induction of hsp70 was noted in the midgut and hemocytes, respectively, by 72 hours postinfection, the level of hsp70 transcription in the fat body of larvae was greater than two orders of magnitude higher than in mock-infected larvae. These results were largely mirrored in cultures of infected cells, and a potentiation effect was observed in cells that were both heat shocked and infected. In contrast, Spodoptera frugiperda multiple nucleopolyhedrovirus and ultraviolet-inactivated HzSNPV did not stimulate hsp70 transcription in these non-permissive larvae and in cell culture, respectively. Taken together, this report documents baculovirus-mediated upregulation of hsp70 in the host and demonstrates the requirement for productive infection for hsp70 induction in vitro and in vivo.

AB N-2-fixing trees can affect stream water quality. This has been documented in temperate streams, but not in tropical ones, even though N-2-fixing trees are prevalent in the tropics. We investigated the effects of the introduced, invasive tree, Falcataria moluccana (albizia) on water quality of Hawaiian streams. Nutrient concentrations were measured in reaches above and below F.moluccana-dominated riparian zones of four streams over 14mo, and benthic algal nutrient limitation was examined in one stream. NO3-+NO2- concentrations were up to 600 percent higher in reaches below F.moluccana stands than in ones above them. In contrast, dissolved organic nitrogen concentrations were 24 percent lower in most reaches below F.moluccana stands, and NH4+ and particulate nitrogen concentrations were similar above and below the stands. Dissolved organic carbon concentrations were up to 30 percent lower below F.moluccana stands, but particulate carbon concentrations were similar between reaches. Total dissolved phosphorus concentrations were similar above and below F.moluccana stands, whereas H4SiO4 concentrations were higher below the stands. In the stream where benthic chlorophyll a was measured, concentrations were three times higher below the F.moluccana stand than above it. Benthic algae were co-limited by nitrogen and phosphorus above the F.moluccana stand, and limited by phosphorus below it. These results suggest that F.moluccana's presence relieved nitrogen-limitation and caused the benthic algae to become solely phosphorus-limited. Overall, our results demonstrate that F.moluccana can strongly affect the chemistry and primary producers of these tropical streams.

AB Aim Both anthropogenic habitat disturbance and the breadth of habitat use by alien species have been found to facilitate invasion into novel environments, and these factors have been hypothesized to be important within coccinellid communities specifically. In this study, we address two questions: (1) Do alien species benefit more than native species from human-disturbed habitats? (2) Are alien species more generalized in their habitat use than natives within the invaded range or can their abundance patterns be explained by specialization on the most common habitats? Location Chile. Methods We quantified the use of different habitat types by native and alien coccinellid beetles by sampling individuals in nine habitat types that spanned a gradient in disturbance intensity, and represented the dominant natural, semi-natural and agricultural habitats in the landscape. Results Our results provide strong support for the hypotheses that more-disturbed habitats are differentially invaded. Both the proportion of alien individuals and the proportion of alien species increased significantly with increasing disturbance intensity. In contrast, we found no evidence that alien species were more generalized in their habitat use than native species; in fact, the trend was in the opposite direction. The abundance of specialized alien coccinellid species was not correlated with the area of the habitat types in the landscape. Main conclusion The results suggest that successfully established alien coccinellid species may be disturbance specialists' that thrive within human-modified habitats. Therefore, less-disturbed agroecosystems are desirable to promote the regional conservation of native species within increasingly human-dominated landscapes.

AB The moisture adsorption isotherms of solar dehydrated mango and jackfruit were determined at temperatures ranging from 30 A degrees C to 50 A degrees C. The equilibrium moisture content (EMC) of mango and jackfruit increased sharply as the temperature increased at water activity (a (w)) above 0.6 and 0.8, respectively. However, there were no clear isothermal intersection points observed at higher a (w) and temperatures. The EMC of solar dehydrated jackfruit showed the isothermal characteristics between types II and III. In contrast, dehydrated mango followed the characteristic type III adsorption isotherms due to high total soluble solids content of 67.8 A degrees Brix and total sugars of 14.21 g/100 g fresh mango. Estimated parameters and fitting ability of three isotherm models were also evaluated. The Guggenheim-Anderson-Boer (GAB) model gave the best fit to the experimental EMC data. The GAB monolayer moisture contents (m (o)) of mango and jackfruit ranged from 11.1-10.0 % and 4.7-3.4 %, respectively. Specific surface area of active binding sites (S) was calculated based on the m (o) values. The S value of dehydrated mango was 2.5 to 2.8 times larger than jackfruit. The maximum net isosteric heat (q (s)) of sorption of solar dehydrated mango and jackfruit were determined as 19.5 and 33 kJ mol(-1), respectively, and q (s) decreased significantly at high moisture.

AB We surveyed the distribution and diversity of fungi associated with eight macroalgae from Antarctica and their capability to produce bioactive compounds. The collections yielded 148 fungal isolates, which were identified using molecular methods as belonging to 21 genera and 50 taxa. The most frequent taxa were Geomyces species (sp.), Penicillium sp. and Metschnikowia australis. Seven fungal isolates associated with the endemic Antarctic macroalgae Monostroma hariotii (Chlorophyte) displayed high internal transcribed spacer sequences similarities with the psychrophilic pathogenic fungus Geomyces destructans. Thirty-three fungal singletons (66%) were identified, representing rare components of the fungal communities. The fungal communities displayed high diversity, richness and dominance indices; however, rarefaction curves indicated that not all of the fungal diversity present was recovered. Penicillium sp. UFMGCB 6034 and Penicillium sp. UFMGCB 6120, recovered from the endemic species Palmaria decipiens (Rhodophyte) and M. hariotii, respectively, yielded extracts with high and selective antifungal and/or trypanocidal activities, in which a preliminary spectral analysis using proton nuclear magnetic resonance spectroscopy indicated the presence of highly functionalised aromatic compounds. These results suggest that the endemic and cold-adapted macroalgae of Antarctica shelter a rich, diversity and complex fungal communities consisting of a few dominant indigenous or mesophilic cold-adapted species, and a large number of rare and/or endemic taxa, which may provide an interesting model of algal-fungal interactions under extreme conditions as well as a potential source of bioactive compounds.

AB Aims To investigate the effects of temperature and medium composition on growth/aflatoxin inhibitory activities of terpenoids gossypol, gossypolone and apogossypolone against Aspergillus flavus and A.parasiticus. Methods and Results The compounds were tested at a concentration of 100gml-1 in a Czapek Dox (Czapek) agar medium at 25, 31 and 37 degrees C. Increased incubation temperature marginally increased growth inhibition caused by these compounds, but reduced the aflatoxin inhibition effected by gossypol. Gossypolone and apogossypolone retained good aflatoxin inhibitory activity against A.flavus and A.parasiticus at higher incubation temperatures. However, increased temperature also significantly reduced aflatoxin production in control cultures. The effects of the terpenoids on fungal growth and aflatoxin production against the same fungi were also determined in Czapek, Czapek with a protein/amino acid addendum and yeast extract sucrose (YES) media. Growth of these fungi in the protein-supplemented Czapek medium or in the YES medium greatly reduced the growth inhibition effects of the terpenoids. Apogossypolone displayed strong anti-aflatoxigenic activity in the Czapek medium, but this activity was significantly reduced in the protein-amended Czapek and YES media. Gossypol, which displayed little to no aflatoxin inhibitory activity in the Czapek medium, did yield significant anti-aflatoxigenic activity in the YES medium. Conclusions Incubation temperature and media composition are important parameters involved in the regulation of aflatoxin production in A.flavus and A.parasiticus. These parameters also affect the potency of growth and aflatoxin inhibitory activities of these gossypol-related compounds against aflatoxigenic fungi. Significance and Impact of the Study Studies utilizing gossypol-related compounds as inhibitory agents of biological activities should be interpreted with caution due to compound interaction with multiple components of the test system, especially serum proteins.

AB Mycobacterium avium subsp. paratuberculosis is shed into the milk and feces of cows with advanced Johne's disease, allowing the transmission of M. avium subsp. paratuberculosis between animals. The objective of this study was to formulate an optimized protocol for the isolation of M. avium subsp. paratuberculosis in milk. The parameters investigated included chemical decontamination with N-acetyl-L-cysteine-sodium hydroxide (NALC-NaOH), alone and in combination with antibiotics (vancomycin, amphotericin B, and nalidixic acid), and the efficacy of solid (Herrold's egg yolk medium [HEY]) and liquid (Bactec 12B and para-JEM) culture media. For each experiment, raw milk samples from a known noninfected cow were inoculated with 10(2) to 10(8) CFU/ml of live M. avium subsp. paratuberculosis organisms. The results indicate that an increased length of exposure to NALC-NaOH from 5 to 30 min and an increased concentration of NaOH from 0.5 to 2.0% did not affect the viability of M. avium subsp. paratuberculosis. Additional treatment of milk samples with the antibiotics following NALC-NaOH treatment decreased the recovery of viable M. avium subsp. paratuberculosis cells more than treatment with NALC-NaOH alone. The Bactec 12B medium was the superior medium of the three evaluated for the isolation of M. avium subsp. paratuberculosis from milk, as it achieved the lowest threshold of detection. The optimal conditions for NALC-NaOH decontamination were determined to be exposure to 1.50% NaOH for 15 min followed by culture in Bactec 12B medium. This study demonstrates that chemical decontamination with NALC-NaOH resulted in a greater recovery of viable M. avium subsp. paratuberculosis cells from milk than from samples treated with hexadecylpyridinium chloride (HPC). Therefore, it is important to optimize milk decontamination protocols to ensure that low concentrations of M. avium subsp. paratuberculosis can be detected.

AB We describe the results of a molecular epidemiological survey of 15 carbapenemase-encoding genes from a recent collection of clinical isolates from Mercy Hospital in Bo, Sierra Leone. The most salient findings revealed that (i) 60% of the isolates harbored multiple carbapenemase genes; (ii) the bla(DIM-1) gene, which has previously only been reported in The Netherlands, is also circulating in this environment; and (iii) bla(OXA-51-like) and bla(OXA-58) genes, which were thought to reside exclusively in Acinetobacter species, can also be found in members of the Enterobacteriaceae.

AB We investigated the frequency of outcrossing in downy brome (Bromus tectorum L.), a cleistogamous weedy annual grass, in both common garden and wild populations, using microsatellite and single nucleotide polymorphic (SNP) markers. In the common garden study, 25 lines with strongly contrasting genotypes were planted in close proximity. We fingerprinted 10 seed progeny from 8 individuals of each line and detected 15 first-generation heterozygotes for a t-value (corrected for cryptic crosses) of 0.0082. Different genotypes were significantly overrepresented as maternal versus paternal parents of heterozygotes, suggesting gender-function-dependent genetic control of outcrossing rates. In 4 wild populations (> 300 individuals each), expected heterozygosity ranged from 0.149 to 0.336, whereas t-values ranged from 0.0027 to 0.0133, indicating high levels of both genetic diversity and inbreeding. Up to a third of the individuals in each population belonged to groups with identical or nearly identical SNP genotypes, whereas many of the remaining individuals were members of loose clusters of apparently related plants that probably represent descendants from past outcrossing events. Strict inbreeding in some lineages within a population with occasional outcrossing in others may be related to positive selection on adaptive syndromes associated with specific inbreeding lineages, or possibly to among-lineage differences in genetic regulation of outcrossing.

AB The genetic relationship of American plains bison (Bison bison bison) and wood bison (Bison bison athabascae) was quantified and compared with that among breeds and subspecies of cattle. Plains bison from 9 herds (N = 136), wood bison from 3 herds (N = 65), taurine cattle (Bos taurus taurus) from 14 breeds (N = 244), and indicine cattle (Bos taurus indicus) from 2 breeds (N = 53) were genotyped for 29 polymorphic microsatellite loci. Bayesian cluster analyses indicate 3 groups, 2 of which are plains bison and 1 of which is wood bison with some admixture, and genetic distances do not show plains bison and wood bison as distinct groups. Differentiation of wood bison and plains bison is also significantly less than that of cattle breeds and subspecies. These and other genetic data and historical interbreeding of bison do not support recognition of extant plains bison and wood bison as phylogenetically distinct subspecies.

AB The hydrolysis of free fatty acids from lipids is a prerequisite for biohydrogenation, a process that effectively saturates free fatty acids. Anaerovibrio lipolyticus 5s and Butyrivibrio fibrisolvens have long been thought to be the major contributors to ruminal lipolysis; however, Propionibacterium avidum and acnes recently have been identified as contributing lipase activity in the rumen. In order to further characterize the lipase activity of these bacterial populations, each was grown with three different lipid substrates, olive oil, corn oil, and flaxseed oil (3 %). Because different finishing rations contain varying levels of glycogen (a source of free glucose) this study also documented the effects of glucose on lipolysis. P. avidum and A. lipolyticus 5s demonstrated the most rapid rates (P < 0.05) of lipolysis for cultures grown with olive oil and flaxseed oil, respectively. A. lipolyticus, B. fibrisolvens, and P. avidum more effectively hydrolyzed flaxseed oil than olive oil or corn oil, especially in the presence of 0.02 % glucose. Conversely, P. acnes hydrolyzed corn oil more readily than olive oil or flaxseed oil and glucose had no effect on lipolytic rate. Thus, these bacterial species demonstrated different specificities for oil substrates and different sensitivities to glucose.

AB Enteric pathogens, including non-typhoidal Salmonella spp. and enterovirulent Escherichia coli, are capable of persisting and multiplying within plants. Yet, little is still known about the mechanisms of these interactions. This study identified the Salmonella yihT gene (involved in synthesis of the O-antigen capsule) as contributing to persistence in immature tomato fruit. Deletion of yihT reduced competitive fitness of S. enterica sv. Typhimurium in green (but not ripe, regardless of color) tomato fruit by approximately 3 logs. The yihT recombinase-based in vivo expression technology (RIVET) reporter was strongly activated in unripe tomato fruit, and fitness of the mutant inversely correlated with the level of the yihT gene expression. Expression of yihT in mature tomato fruit was low, and yihT did not affect competitive fitness within mature fruit. To better understand the molecular basis of the phenotype, behaviors of the yihT RIVET reporter and the yihT mutant were tested in tomato fruit defective in ethylene signaling. These experiments suggest a role for functional ethylene-mediated signaling in the persistence of Salmonella spp. within tomato fruit. Furthermore, jasmonic acid and its precursors strongly reduced expression of yihT.

AB Many studies in which gene expression is quantified by polymerase chain reaction represent the expression of a gene of interest (GOI) relative to that of a reference gene (RG). Relative expression is founded on the assumptions that RG expression is stable across samples, treatments, organs, etc., and that reaction efficiencies of the GOI and RG are equal; assumptions which are often faulty. The true variability in RG expression and actual reaction efficiencies are seldom determined experimentally. Here we present a rapid and robust method for absolute quantification of expression in Vitis where varying concentrations of genomic DNA were used to construct GOI standard curves. This methodology was utilized to absolutely quantify and determine the variability of the previously validated RG ubiquitin (VvUbi) across three test studies in three different tissues (roots, leaves and berries). In addition, in each study a GOI was absolutely quantified. Data sets resulting from relative and absolute methods of quantification were compared and the differences were striking. VvUbi expression was significantly different in magnitude between test studies and variable among individual samples. Absolute quantification consistently reduced the coefficients of variation of the GOIs by more than half, often resulting in differences in statistical significance and in some cases even changing the fundamental nature of the result. Utilizing genomic DNA-based absolute quantification is fast and efficient. Through eliminating error introduced by assuming RG stability and equal reaction efficiencies between the RG and GOI this methodology produces less variation, increased accuracy and greater statistical power.

AB Calcium has been shown to enhance stress tolerance, maintain firmness and reduce decay in fruits. Previously we reported that seven tomato SlSRs encode calcium/calmodulin-regulated proteins, and that their expressions are developmentally regulated during fruit development and ripening, and are also responsive to ethylene. To study their expressions in response to stresses encountered during postharvest handling, tomato fruit at the mature-green stage was subjected to chilling and wounding injuries, infected with Botrytis cinerea and treated with salicylic acid or methyl jasmonate. Gene expression studies revealed that the seven SlSRs differentially respond to different stress signals. SlSR2 was the only gene upregulated by all the treatments. SlSR4 acted as a late pathogen-induced gene; it was upregulated by salicylic acid and methyl jasmonate, but downregulated by cold treatment. SlSR3L was cold- and wound-responsive and was also induced by salicylic acid. SlSR1 and SlSR1L were repressed by cold, wounding and pathogen infection, but were upregulated by salicylic acid and methyl jasmonate. Overall, results of these expression studies indicate that individual SlSRs have distinct roles in responses to the specific stress signals, and SlSRs may act as a coordinator(s) connecting calcium-mediated signaling with other stress signal transduction pathways during fruit ripening and storage.

AB Previously, we hypothesized that summer "extreme" diurnal temperature highs in the southeastern United States were responsible for the yearly absence or delay of soybean rust development until fall. Utilizing temperature-controlled growth chambers, a diurnal temperature pattern of 33 degrees C high and 20 degrees C low reduced urediniospore production by 81%. However, that study did not consider the influence of frequency of extreme temperatures on soybean rust. We now report that a temperature high of 35 degrees C for 1 h on three consecutive days, initiated 15 days after inoculation, when lesions had formed, reduced urediniospore production by 50% and required 9 to 12 days for sporulation to resume once the extreme temperature highs ceased. Furthermore, three consecutive days in which the temperature high was 37 degrees C, beginning immediately after inoculation and subsequent dew period, reduced lesion numbers by 60%. The combined effects of reduced numbers of lesions and urediniospores per lesion caused by extreme temperature highs can account for observed absence or delay of soybean rust development in the southeastern United States until fall. A comparison of frequency of extreme temperature highs with numbers of counties reporting presence of soybean rust from 2005 to 2012 verified that extreme temperature highs may be largely responsible for absence or delay of soybean rust development. This is the first report showing the effect of frequency of extreme temperature highs on development of soybean rust. Because the south-to-north progression of soybean rust is required for the disease to occur in the major soybean-production regions of the United States, temperatures in the southeastern United States have a major effect on the entire U.S. soybean industry.

AB The formation of chasmothecia by the strawberry powdery mildew pathogen (Podosphaera aphanis) is widespread but often sporadic throughout the range of strawberry cultivation. In some production regions, notably in warmer climates, chasmothecia are reportedly rare. We confirmed that the pathogen is heterothallic, and that initiation of chasmothecia is not only dependent upon the presence of isolates of both mating types but also largely suppressed at temperatures >13 degrees C. Compared with incubation at a constant temperature of 25 degrees C, progressively more chasmothecia were initiated when temperatures were decreased to 13 degrees C for progressively longer times. At lower temperatures, production of chasmothecia was associated with a decline in but not total cessation of conidial formation, and pairings of compatible isolates sporulated abundantly at 25 degrees C. We developed mating-type markers specific to P. aphanis and used these to confirm the presence of both mating types in populations that had not yet initiated chasmothecia. The geographic discontinuity of chasmothecia production and the sporadic and seemingly unpredictable appearance of chasmothecia in P. aphanis are possibly due to the combined influence of heterothallism and suppression of chasmothecia formation by high temperatures.

AB Genetic and phenotypic diversity and population differentiation of Sclerotinia sclerotiorum isolates infecting canola from China and the United States were investigated. Genetic diversity was assessed with eight microsatellite markers and mycelial compatibility groups (MCGs). Phenotypic diversity was assessed with sensitivity to three fungicides, production of oxalate and sclerotia, growth rate, and virulence on two canola cultivars. No shared MCGs or multilocus haplotypes were detected between the two populations, and populations differed significantly (P < 0.001). Recombination was detected in both populations but was greater in the Chinese population. A polymerase chain reaction detection assay showed that 60% of the isolates were inversion-plus at the mating type locus. The two populations differed significantly (P < 0.05) for all of the phenotypic traits except for sensitivity to fungicide fluazinam and virulence. Isolates in the Chinese population were unique in several aspects. Despite the phenotypic differentiation, heritabilities of the phenotypic traits were similar for both populations. Significant correlations were found among five phenotypic traits. Cross resistance to benomyl and iprodione was detected. Virulence was not significantly correlated with any other phenotypic trait and had the least heritability. However, both populations were equally virulent on either a susceptible or a moderately resistant canola cultivars.

AB Introduction: Preeclampsia and other placental pathologies are characterized by a lack of spiral artery remodeling associated with insufficient invasion by extravillous trophoblast cells (EVT). Because trophoblast invasion occurs in early pregnancy when access to human placental tissue is limited, there is a need for model systems for the study of trophoblast differentiation and invasion. Human embryonic stem cells (hESC) treated with BMP4- differentiate to trophoblast, and express HLA-G, a marker of EVT. The goals of the present study were to further characterize the HLA-G(+) cells derived from BMP4-treated hESC, and determine their suitability as a model.
Methods: HESC were treated with BMP4 under 4% or 20% oxygen and tested in Matrigel invasion chambers. Both BMP4-treated hESC and primary human placental cells were separated into HLA-G(+) and HLA-G(-)/TACSTD2(+) populations with immunomagnetic beads and expression profiles analyzed by microarray.
Results: There was a 10-fold increase in invasion when hESC were BMP4-treated. There was also an independent, stimulatory effect of oxygen on this process. Invasive cells expressed trophoblast marker KRT7, and the majority were also HLA-G(+). Gene expression profiles revealed that HLA-G(+), BMP4-treated hESC were similar to, but distinct from, HLA-G(+) cells isolated from first trimester placentas. Whereas HLA-G(+) and HLA-G(-) cells from first trimester placentas had highly divergent gene expression profiles, HLA-G(+) and HLA-G(-) cells from BMP4-treated hESC had somewhat similar profiles, and both expressed genes characteristic of early trophoblast development.
Conclusions: We conclude that hESC treated with BMP4 provide a model for studying transition to the EVT lineage. (C) 2013 Elsevier Ltd. All rights reserved.

AB Wheat landraces provide a source of genetic variability for breeding. The emergence and spread of highly virulent races of the stem rust pathogen (Ug99 race group of Puccinia graminis f. sp. tritici) threaten wheat production globally. Spring wheat landraces were screened for resistance in eight field seasons at the Kenya Agricultural Research Institute, Njoro, where the Ug99 race group has become endemic. Accessions showing resistance in one season were retested and screened with molecular markers associated with resistance genes Sr2, ST24, Sr36, and Lr34/Yr18; two height-reducing genes; and a photoperiod insensitivity allele. Of 2,509 accessions tested, 278 were categorized as resistant based on results from at least two seasons. Of these resistant accessions, 32 were positive for one or more markers for Sr2, Sr36, Rht-B1b, or Rht-D1b, indicating that they do not fit the definition of "landrace" because these genes were likely introduced via modern breeding practices. Thus, 246 resistant "landrace" accessions were identified. Of countries with more than five tested accessions, Afghanistan, Iran, Portugal, Ethiopia, Uzbekistan, Greece, Tajikistan, Bosnia and Herzegovina, and Serbia had at least 10% of tested accessions that were resistant to the Ug99 race group. Future research will characterize the resistance to determine its novelty and incorporate novel genes into improved lines.

AB Triticum mosaic virus (TriMV) is a recently discovered virus infecting wheat. We compared Colorado isolates C10-492 and C11-775 with the 06-123 isolate. Comparisons were made using enzyme-linked immunosorbent assay (ELISA), infectivity assay, host range, thy weight (DW), inoculation of 'Mace' wheat with temperature-sensitive resistance to Wheat streak mosaic virus, and the deduced amino acid sequence of the coat proteins (CP) and P1 proteins. Both C10-492 and C11-775 infected 'Gallatin' barley and, when compared with 06-123, had significantly reduced ELISA values and virus titers in wheat. Both Colorado isolates caused symptomless infections in Mace, whereas 06-123 caused mosaic symptoms. The amino acid sequences of the CP differed by two and one amino acids for C10-492 and C11-775, respectively, compared with 06-123. The sequence of C10-492 differed from C11-775 by one amino acid. The P1 amino acid sequence of C10-492 and C11-775 differed from 06-123 by three and one amino acids, respectively. The C10-492 and C11-775 isolates reduced DW significantly in 'Karl 92' but significantly less than 06-123. In '2317' wheat, the Colorado isolates did not consistently cause significant reduction in DW, while 06-123 did. The data collectively indicate that C10-492 and C11-775 are isolates of TriMV showing biological behavior diverse from that of 06-123.

AB In eastern North America, Phomopsis cane and leaf spot, caused by Phomopsis viticola, is a foliar disease of grape but, in the Mediterranean climate of western North America, P viticola is primarily associated with wood cankers, along with other Diaporthe spp. To determine the identity of wood-infecting Diaporthe spp. in eastern North America, 65 isolates were cultured from 190 wood-canker samples from 23 vineyards with a history of Phomopsis cane and leaf spot. Identification of 29 representative isolates was based initially on morphology, followed by phylogenetic analyses of DNA sequences of the ribosomal DNA internal transcribed spacer region, elongation factor subunit 1-alpha, and actin in comparison with those of type specimens. Three species were identified: P. viticola, P. fukushii, and Diaporthe eres. Inoculations onto woody stems of potted Vitis labruscana 'Concord' and V vinifera 'Chardonnay' showed that D. eres and P. fukushii were pathogenic (mean lesion lengths of 7.4 and 7.1 mm, respectively, compared with 3.5 mm for noninoculated controls) but significantly less so than wood-canker and leaf-spot isolates of P. viticola (13.5 mm). All three species infected pruning wounds of Concord and Chardonnay in the field. Our finding of pathogenic, wood-infecting Diaporthe spp. in all 23 vineyards suggests a frequent co-occurrence of the foliar symptoms of Phomopsis cane and leaf spot and wood cankers, although the latter are not always due to P. viticola.

AB Fusarium oxysporum f. sp. spinaciae, causal agent of spinach Fusarium wilt, is an important soilborne pathogen in many areas of the world where spinach is grown. The pathogen is persistent in acid soils of maritime western Oregon and Washington, the only region of the United States suitable for commercial spinach seed production. A TaqMan real-time polymerase chain reaction (PCR) assay was developed for rapid identification and quantification of the pathogen, based on sequencing the intergenic spacer (IGS) region of rDNA of isolates of the pathogen. A guanine single-nucleotide polymorphism (G SNP) was detected in the IGS sequences of 36 geographically diverse isolates of E oxysporum f. sp. spinaciae but not in the sequences of 64 isolates representing other formae speciales and 33 isolates representing other fungal species or genera. The SNP was used to develop a probe for a real-time PCR assay. The real-time PCR assay detected E oxysporum f. sp. spinaciae at 3-14,056 CFU/g of soil in 82 soil samples collected over 3 years from naturally infested spinach seed production sites in western Washington, although a reliable detection limit of the assay was determined to be 11 CFU/g of soil. A significant (P < 0.05), positive correlation between enumeration of F. oxysporum on Komada's agar and quantification of the pathogen using the TaqMan assay was observed in a comparison of 82 soil samples. Correlations between pathogen DNA levels, Fusarium wilt severity ratings, and spinach biomass were significantly positive for one set of naturally infested soils but not between pathogen DNA levels, wilt incidence ratings, and spinach biomass for other soil samples, suggesting that soilborne pathogen population is not the sole determinant of spinach Fusarium wilt incidence or severity. The presence of the G SNP detected in one isolate of each of E oxysporum ff. spp. lageneriae, lilii, melongenae, and raphani and reaction of the real-time PCR assay with 16 of 22 nonpathogenic isolates of E oxysporum associated with spinach plants or soil in which spinach had been grown potentially limits the application of this assay. Nonetheless, because all isolates of E oxysporum f. sp. spinaciae tested positive with the real-time PCR assay, the assay may provide a valuable means of screening for resistance to Fusarium wilt by quantifying development of the pathogen in spinach plants inoculated with the pathogen.

AB Passive management to preserve endangered plant species involves measures to avoid anthropogenic disturbance of natural populations, but this approach may not sustain plants that require disturbance-maintained habitats. Active management is often necessary to maintain existing habitats or provide new habitats for endangered species recovery. Our objective was to examine the effects of two disturbances in floodplain forests, soil flooding and light availability, on survival, stem length, stem diameter and ramet production of endangered Lindera melissifolia (Walt.) Blume. We used a water impoundment facility to control the timing and duration of flooding (0, 45 or 90 days) and shade houses to vary light availability (70, 63 or 5 % ambient light). Hydroperiod had little direct effect on steckling survival, stem length growth and stem diameter growth, supporting indications that soil flooding may be important for reduction of interspecific competition in L. melissifolia habitat. Greater ramet production by stecklings receiving no soil flooding likely resulted from longer periods of favorable soil conditions during each growing season. Positive stem length growth and stem diameter growth under all light levels demonstrates the plasticity of this species to acclimate to a range of light environments, though, greatest survival and stem length growth occurred when L. melissifolia received 37 % light, and stem diameter growth was greatest beneath 70 % light. Further, female clones produced more ramets as light availability increased. These results indicate that passive management absent natural disturbance could jeopardize sustainability of extant L. melissifolia populations, and this species would respond favorably to active management practices that create canopy openings to increase understory light availability.

AB Aluminum (Al) toxicity is one of the major constraints for wheat production in acidic soils worldwide and use of Al-tolerant cultivars is one of the most effective approaches to reduce Al damage in the acidic soils. A Chinese landrace, FSW, shows a high level of tolerance to Al toxicity and a mapping population of recombinant inbred lines (RILs) was developed from a cross between FSW and Al-sensitive US spring wheat cultivar Wheaton to validate the quantitative trait loci (QTL) previously identified in FSW. The mapping population was evaluated for net root growth (NRG) during Al stress in a nutrient solution culture and hematoxylin staining score (HSS) of root tips after Al stress. After 132 simple sequence repeat (SSR) markers from three chromosomes that were previously reported to have the QTLs were analyzed in the population, two QTLs for Al tolerance from FSW were confirmed. The major QTL on chromosome 4DL co-segregated with the Al-activated malate transporter gene (ALMT1), however, sequence analysis of the promoter region (Ups4) of ALMT1 gene indicated that FSW contained a marker allele that is different from the one that was reported to condition Al tolerance in the Brazilian source. Another QTL on chromosome 3BL showed a minor effect on Al tolerance in the population. The two QTLs accounted for about 74.9 % of the phenotypic variation for HSS and 72.1 % for NRG and demonstrated an epistatic effect for both HSS and NRG. SSR markers closely linked to the QTLs have potential to be used for marker-assisted selection (MAS) to improve Al tolerance in wheat breeding programs.

AB Sulfakinins (SK) are multifunctional neuropeptides widely found in insects that are structurally and functionally homologous to the mammalian gastrin/cholecystokinin (CCK) neuropeptides. CCK is involved in various biological processes such as the feeding regulation where it induces satiety. In this project we characterized SK and SK receptor (SKR) of an important pest and model beetle insect, the red flour beetle Tribolium castaneum, with the aim to better understand the SK signaling pathway and its function in food intake. The sk gene encoded a SK precursor with 113 amino acids and the skr gene a seven-transmembrane SKR with 554 amino acids. Both genes were expressed in the larval, pupal and adult stages with different expression levels in tested tissues. By RNA interference, sk dsRNA and skr dsRNA reduced the expression of the corresponding target gene by 80-90% and 30-50%, respectively, and stimulated food intake in the larvae. In parallel, we injected insects with a SK analog reducing food intake. In conclusion, the data are discussed in relation to the SK signaling pathway and its physiological-endocrinological role in regulating food intake and potential usage in the control of important pest insects.

AB A comprehensive survey of channel catfish Toll-like receptors (TLRs) was undertaken following a genomic PCR approach based on degenerate primers. Twenty different TLRs were identified in channel catfish. Channel catfish TLR sequences were characterized by phylogenetic analysis based on their conserved Toll/interleukin-1 receptor domain and by in-depth analysis of leucine-rich repeat (LRR) motifs of the ligand binding extracellular domain (ECD). The catfish have representatives of all the TLR types defined in vertebrates with the exception of TLR6, TLR10, TLR11, TLR12, TLR13, TLR15, TLR23, and TLR24. Additionally, two new types were discovered: TLR25 and TLR26. TLR25 is also present in cyprinids, cichlids, plecoglossids, and adrianichthyids, suggesting its presence early in fish evolution. To date, TLR26 was found only in channel catfish. Like TLR18-23, TLR25 and TLR26 were not found in any other vertebrate classes and appear to be fish specific. Data mining using the catfish TLR sequences revealed that in addition to ictalurids and cyprinids, TLR4 is also present in salmonids. TLR19 and TLR20 were both found in ictalurids, cyprinids, and salmonids, demonstrating a wider range than previously known. The LRR structure within ECDs appeared generally well conserved. TLR7 demonstrated a very high identity to human TLR7 strongly suggesting that ligand specificity maybe conserved. Finally, expression profiling confirmed that most TLRs are widely expressed in a diversity of tissues and revealed marked differences of expression level.

AB Irrigation with water of poor microbiological quality can elevate levels of bacteria on produce. This study aimed to identify climate and management variables associated with generic Escherichia coli in irrigation water on leafy green produce farms and to measure the prevalence of E. colt 0157 and Salmonella spp. in irrigation and non-irrigation water sources on these farms. Water and sediment samples collected from various points along irrigation systems, as well as from streams and ponds on farms on the Central California coast between May 27th, 2008 and October 26th, 2010 were cultured for generic E. colt (MPN/100 mL or cfu 100 g) (n = 436), E. coli 0157 (n = 437), and (n = 163) Salmonella. Variables were based on grower's management practices, landscape features in proximity to samples (e.g., distance to roads and ranches/livestock), and climate data accessed from an online database. Negative binomial regression models were constructed to test associations between generic E. coli (MPN/100 mL) in water from farms and variables. Arithmetic mean concentration of E. coli for water, not including those from Moore swabs, and sediment samples, was 7.1 x 10(2) MPN/100 mL and 1.0 x 10(4) cfu/100 g, respectively. Matched by collection day, E. coli concentration in sediment (cfu/100 g) was typically 10- to 1000-fold higher than the overlying water (MPN/100 mL) for these irrigation systems. Generic E. coli concentration (MPN/100 mL) increased by 60.1% for each 1 m/s increase in wind speed and decreased by 3% for each 10 m increase in the distance between the sample location and rangeland. Moore swabs detected a higher proportion of E. coli 0157 (13.8%) positive water samples compared to grab samples (1.8%); 1.7% of sediment samples had detectable levels of this pathogen. Interestingly, season was not significantly associated with E. coli 0157 presence in water or sediments from produce farms or water sources with public access. Salmonella was detected in 6% (6/96) water and 43% (3/67) sediment samples. Generic E. coli concentration was not significantly associated with the presence of either E. coli 0157 or Salmonella in water or sediment samples, suggesting that, for this 2.5-year period and geographical location, generic E. coli would likely be an unreliable indicator bacteria for predicting the presence of these food- and waterborne pathogens in a key produce production environment.

AB High-resolution daily evapotranspiration (ET) maps would greatly improve irrigation management. Numerous ET mapping algorithms have been developed to make use of thermal remote sensing data acquired by satellite sensors. However, adoption of remote sensing-based ET maps for irrigation management has not been feasible due to inadequate spatial and temporal resolution of ET maps. Data from a coarse spatial resolution image in agricultural fields often cause inaccurate ET estimation because of a high level of spatial heterogeneity in land use. Image downscaling methods have been utilized to overcome spatial and temporal scaling issues in numerous remote sensing applications. In the field of hydrology, the image downscaling method has been used to improve spatial resolution of remote sensing-based ET maps for irrigation scheduling purposes and thus improves estimation of crop water requirements. This paper (part I) reviews downscaling methods to improve spatial resolution of land surface characteristics such as land surface temperature or ET. Each downscaling method was assessed and compared with respect to their capability of downscaling spatial resolutions of images. The companion paper (part II) presents review of image fusion methods that are also designed to increase spatial resolutions of images by integrating multi-spectral and panchromatic images.

MULTISPECTRAL IMAGES
AB Satellite-based sensors provide data at either greater spectral and coarser spatial resolutions or lower spectral and finer spatial resolutions due to complementary spectral and spatial characteristics of optical sensor systems. In order to overcome this limitation, image fusion has been suggested to obtain higher spatial and spectral resolution images at the same time. Image fusion has been a valuable technique in digital image analysis and comparison because of the availability of multi-spatial and multispectral images from satellite and airborne sensors. It has been applied to merge coarser spatial resolution of multispectral images with a finer spatial resolution panchromatic image to enhance visual apprehension and to provide images that are more informative. Part I companion paper presented and discussed the image downscaling methods. In this paper (part II), the main objective is to review existing image fusion methods for their capability to downscale coarser spatial resolution images for irrigation management applications. A literature review indicated that image fusion methods have not been actively used in obtaining high-resolution land surface temperature (LST) and evapotranspiration (ET) images for irrigation management. However, there is a great potential for applying image fusion methods to retrieve finer LST and ET images from coarser thermal images by fusing them with finer non-thermal color or panchromatic images for irrigation scheduling and management purposes.

SO IRRIGATION SCIENCE

ID WIRELESS SENSOR NETWORK; CROP CANOPY TEMPERATURE; DEFICIT IRRIGATION;
PRECISION AGRICULTURE; WATER PRODUCTIVITY; MANAGEMENT; AUTOMATION
AB More than 20 years of private and public research on site-specific variable rate sprinkler irrigation (SS-VRI) technology on self-propelled center pivot and linear move irrigation systems has resulted in limited commercial adoption of the technology. Competing patents, liability, and proprietary software have affected industry's willingness to move into a new technology area. Documented and proven water conservation strategies using site-specific irrigation are quite limited. Marginal costs associated with site-specific technologies are high. Although sales of SS-VRI are increasing, they are primarily being used for eliminating irrigation and chemigation on non-cropped areas of a field or for land application of liquid agricultural and municipal wastes. Various aspects of SS-VRI technologies for general crop production are beginning to slowly gain widespread acceptance; however, their uses are largely focused on addressing symptoms of poor design and sub-optimal water and nutrient management. Although currently underutilized, SS-VRI technology has the potential to positively impact crop water productivity, water and energy conservation, and the environment. There are also few economic incentives to motivate growers to move to higher levels of SS-VRI management. Greater adoption rates will likely require higher costs for water and energy, severely restricted water diversions on a broad scale, and enforcement of compliance with environmental and other regulations. Sustainable use of SS-VRI will require strong research support, which is currently limited. In the short term, adoption of SS-VRI technologies will be enhanced by addressing equipment deficiencies and research developing basic criteria and systems for defining management zones and locations of various sensor systems for both arid and humid regions. Training adequate personnel to help write site-specific variable rate irrigation prescriptions in humid and arid areas to assist growers with the decision-making process is also a high priority. There is also a large need to educate government boards and bankers on the potential benefits of these systems. The long-term challenges will be to demonstrate that SS-VRI will improve water management or increase net returns. There is a critical need to develop fully integrated management systems with supporting elements that accurately and inexpensively define dynamic management zones, sense within-field variability in real time, and then adaptively control site-specific variable rate water applications, which will be challenging as significant knowledge gaps exist.

AB Tests were conducted to evaluate whether Solenopsis invicta virus 3 (SINV-3) could be delivered in various bait formulations to fire ant colonies and measure the corresponding colony health changes associated with virus infection in Solenopsis invicta. Three bait formulations (10% sugar solution, cricket paste, and soybean oil adsorbed to defatted corn grit) effectively transmitted SINV-3 infections to S. invicta colonies. Correspondingly, viral infection was shown to be detrimental to colony health and productivity. By day 32, all ant colonies exposed to a single 24 h pulse treatment of SINV-3 became infected with the virus regardless of the bait formulation. However, the SINV-3 sugar and cricket bait-treated colonies became infected more rapidly than the oil-treated colonies. Sugar and cricket-treated colonies exhibited significant declines in their brood ratings compared with the untreated control and oil bait-treated colonies. Measures of colony health and productivity evaluated at the end of the study (day 47) showed a number of differences among the bait treatments and the control group. Statistically significant and similar patterns were exhibited among treatments for the quantity of live workers (lower), live brood (lower), total colony weight (lower), worker mortality (higher), proportion larvae (lower), and queen weight (lower). Significant changes were also observed in the number of eggs laid by queens (lower) and the corresponding ovary rating in SINV-3-treated colonies. The study provides the first successful demonstration of SINV-3 as a potential biopesticide against fire ants. Published by Elsevier Inc.

AB Solenopsis invicta virus 1 (SINV-1) was found regularly and prevalently in S. invicta. In sampled locations where S. invicta and S. geminata are sympatric (specifically, Gainesville, FL and Travis, TX), SINV-1 was detected in S. geminata. Conversely, in areas in which S. geminata and S. invicta are allopatric, SINV-1 was not detected in S. geminata; these locations included north Australia (n = 12), southern Mexico (n = 107), Hawaii (n = 48), Taiwan (n = 12), and the Johnston Atoll (n = 6). A similar relationship was observed for S. richteri. In areas in which S. invicta and S. richteri were sympatric, SINV-1 was detected in the S. richteri population, but in areas in which S. invicta and S. richteri were allopatric, SINV-1 was not detected. These occurrences suggest that S. invicta is the host of predilection, or preferred host for SINV-1, and that the congenerics, S. geminata and S. richteri serve as either accidental, reservoir, or transfer hosts. The minus genome strand of SINV-1 was detected in S. geminata and S. richteri indicating that these species may serve as functional hosts capable of supporting SINV-1 replication. SINV-1 was not detected in S. xyloni regardless of its proximity to S. invicta. These results suggest that SINV-1 may be an example of pathogen spillover or pollution. Published by Elsevier Inc.

AB The demonstrated link between the emergence of H3N2 variant (H3N2v) influenza A viruses (IAVs) and swine exposure at agricultural fairs has raised concerns about the human health risk posed by IAV-infected swine. Understanding the antigenic profiles of IAVs circulating in pigs at agricultural fairs is critical to developing effective prevention and control strategies. Here, 68 H3N2 IAV isolates recovered from pigs at Ohio fairs (2009 to 2011) were antigenically characterized. These isolates were compared with other H3 IAVs recovered from commercial swine, wild birds, and canines, along with human seasonal and variant H3N2 IAVs. Antigenic cartography demonstrated that H3N2 IAV isolates from Ohio fairs could be divided into two antigenic groups: (i) the 2009 fair isolates and (ii) the 2010 and 2011 fair isolates. These same two antigenic clusters have also been observed in commercial swine populations in recent years. Human H3N2v isolates from 2010 and 2011 are antigenically clustered with swine-origin IAVs from the same time period. The isolates recovered from pigs at fairs did not cross-react with ferret antisera produced against the human seasonal H3N2 IAVs circulating during the past decade, raising the question of the degree of immunity that the human population has to swine-origin H3N2 IAVs. Our results demonstrate that H3N2 IAVs infecting pigs at fairs and H3N2v isolates were antigenically similar to the IAVs circulating in commercial swine, demonstrating that exhibition swine can function as a bridge between commercial swine and the human population.

TI Meta-analyses of habitat selection by fishers at resting sites in the

ID MARTES-PENNANTI; CALIFORNIA
AB The fisher (Pekania pennanti) is a species of conservation concern throughout the Pacific coastal region in North America. A number of radiotelemetry studies of habitat selection by fishers at resting sites have been conducted in this region, but the applicability of observed patterns beyond the boundaries of each study area is unknown. Broadly applicable information on habitat selection by fishers in this region would be useful for conservation planning and for informing forest management decisions in areas where intensive field studies have not been conducted. To provide such information, we conducted formal meta-analyses of habitat selection by fishers at resting sites in 8 study areas located from central British Columbia to the southern Sierra Nevada in California, including all areas that currently contain established fisher populations. Each study included in the meta-analyses measured environmental attributes at sites used by fishers for resting (i.e., the immediate vicinity of resting structures; typically 0.5ha) and at random or systematically located sites representing resource availability in each study area. We selected 9 environmental attributes that we expected to be associated with fisher resting sites: slope, heat load index, percent cover of vegetation 2m above the ground, volume of moderately decayed logs 26cm in mean diameter, basal area of live conifers 51-100cm in diameter at breast height (dbh), basal area of live hardwoods 51-100cm in dbh, basal area of moderately decayed snags 51-100cm in dbh, mean dbh of live conifers 10cm in dbh, and mean dbh of live hardwoods 10cm in dbh. Despite substantial variation in environmental conditions among study locations, our analyses revealed statistically significant summary effect sizes for each of the 9 environmental attributes we analyzed. Fishers selected sites for resting that had steeper slopes, cooler microclimates, denser overhead cover, a greater volume of logs, and a greater prevalence of large trees and snags than were generally available. Thus, in areas within the Pacific coastal region where fishers have not been studied and data on selection of resting sites are lacking, our findings provide empirical support for management or conservation actions for fishers that promote the retention or development of these environmental attributes.

ID OPEN SPACE; IMPUTATION; NITROGEN; VALUES
AB Lawn fertilization is increasingly recognized as an important contributor to non-point source pollution in watersheds, but relatively little is known about how and why homeowners fertilize. Lawns are a social expression of citizenship and belonging in many American cities, for a well-maintained yard reflects a homeowner's work ethic as well as the pride in his home. There are also neighborhood influences, as homeowners conform to the dominant neighborhood standard of lawn esthetics. Homeowners associations (HOAs) are one way in which neighborhood lawn standards are maintained, as they use written rules and unwritten expectations backed by legal means of enforcement to ensure compliance with neighborhood guidelines. This paper examines household nitrogen fertilizer application rates in Baltimore, Maryland. We find that households which place a high importance on lawn care and occupy more valuable homes fertilize at higher rates compared with neighbors who place lower importance on lawn care, and live in less expensive homes. We also examine the effects of different neighborhood governance regimes, specifically homeowners associations and neighborhood associations. Households who belong to an HOA apply more fertilizer than those who do not, but households belonging to a neighborhood association do not fertilize more than their counterparts who are not so affiliated. HOA membership also mediates the effect of lawn care importance and home value and moderates the effect of social cohesion on fertilization application rates. HOAs shape household lawn behaviors: by obliging people to maintain a high esthetic standard, they encourage higher usage of chemicals to attain those standards. (C) 2013 Elsevier B.V.

AB Plants form ubiquitous associations with diverse microbes. These interactions range from parasitism to mutualism, depending partly on resource supplies that are being altered by global change. While many studies have considered the separate effects of pathogens and mutualists on their hosts, few studies have investigated interactions among microbial mutualists and pathogens in the context of global change. Using two wild grass species as model hosts, we grew individual plants under ambient or elevated CO2, and ambient or increased soil phosphorus (P) supply. Additionally, individuals were grown with or without arbuscular mycorrhizal inoculum, and after 2wk, plants were inoculated or mock-inoculated with a phloem-restricted virus. Under elevated CO2, mycorrhizal association increased the titer of virus infections, and virus infection reciprocally increased the colonization of roots by mycorrhizal fungi. Additionally, virus infection decreased plant allocation to root biomass, increased leaf P, and modulated effects of CO2 and P addition on mycorrhizal root colonization. These results indicate that plant mutualists and pathogens can alter each other's success, and predict that these interactions will respond to increased resource availability and elevated CO2. Together, our findings highlight the importance of interactions among multiple microorganisms for plant performance under global change.

AB In this study our aim was to value the benefits of rapid effective trace-back capability-based on a livestock identification system - in the event of a foot and mouth disease (FMD) outbreak. We simulated an FMD outbreak in the Texas High Plains, an area of high livestock concentration, beginning in a large feedlot. Disease spread was simulated under different time dependent animal tracing scenarios. In the specific scenario modeled (incursion of FMD within a large feedlot, detection within 14 days and 90% effective tracing), simulation suggested that control costs of the outbreak significantly increase if tracing does not occur until day 10 as compared to the baseline of tracing on day 2. In addition, control costs are significantly increased if effectiveness were to drop to 30% as compared to the baseline of 90%. Results suggest potential benefits from rapid effective tracing in terms of reducing government control costs; however, a variety of other scenarios need to be explored before determining in which situations rapid effective trace-back capability is beneficial.

AB Raising chickens in urban settings is a growing phenomenon in the United States. The United States Department of Agriculture's (USDA) National Animal Health Monitoring System (NAHMS) conducted a cross-sectional study to better understand health and management of privately owned chicken flocks, and Salmonella awareness among chicken owners, in three urban settings Denver, Colorado; Los Angeles, California; and Miami, Florida. Feed stores in each city were visited by data collectors during summer 2010, and customers who owned chickens were asked to complete a questionnaire. A convenience sample of 449 feed store customers was selected, and 382 (85.1%) customers participated in the study. For analysis, a stratified random sample was assumed, with the strata being individual feed stores.
Median flock sizes were 5, 11 and 19 chickens in Denver, Los Angeles and Miami, respectively. In all three cities, over three-fourths of flocks contained table egg chicken breeds on the day the questionnaire was completed. In Denver, 20.4% of flocks had another species of bird present in addition to chickens, compared with 65.6% of flocks in Los Angeles and 53.6% of flocks in Miami.
At the time of data collection in 2010, less than 50% of respondents in Miami and Los Angeles (40.0 and 30.2%, respectively) were aware of a connection between poultry contact, such as contact with chicks or ducks, and Salmonella infection in people, compared to 63.5% of respondents in Denver. Urban chicken flock owners who completed the questionnaire in English were more likely to be aware of the connection between poultry contact and Salmonella, compared with respondents who completed the questionnaire in Spanish (OR=3.5). The likelihood of Salmonella awareness was also higher for respondents who had heard of USDA's Biosecurity for Birds educational campaign and for respondents who sold or gave away eggs from their flocks (OR=2.5 and 2.8, respectively).
Study findings demonstrate the importance of reaching the Spanish speaking population when creating educational outreach programs to reduce Salmonella infections in people who have live poultry contact. Published by Elsevier B.V.

AB Epidemiologic simulation modeling of highly pathogenic avian influenza (HPAI) outbreaks provides a useful conceptual framework with which to estimate the consequences of HPAI outbreaks and to evaluate disease control strategies. The purposes of this study were to establish detailed and informed input parameters for an epidemiologic simulation model of the H5N1 strain of HPAI among commercial and backyard poultry in the state of South Carolina in the United States using a highly realistic representation of this poultry population; to estimate the consequences of an outbreak of HPAI in this population with a model constructed from these parameters; and to briefly evaluate the sensitivity of model outcomes to several parameters. Parameters describing disease state durations; disease transmission via direct contact, indirect contact, and local-area spread; and disease detection, surveillance, and control were established through consultation with subject matter experts, a review of the current literature, and the use of several computational tools. The stochastic model constructed from these parameters produced simulated outbreaks ranging from 2 to 111 days in duration (median 25 days), during which 1 to 514 flocks were infected (median 28 flocks). Model results were particularly sensitive to the rate of indirect contact that occurs among flocks. The baseline model established in this study can be used in the future to evaluate various control strategies, as a tool for emergency preparedness and response planning, and to assess the costs associated with disease control and the economic consequences of a disease outbreak.

AB Influential analyses of the propagule pressure hypothesis have been based on multiple bird species introduced to one region (e.g. New Zealand). These analyses implicitly assume that species-level and site-level characteristics are less important than the number of individuals released. In this study we compared records of passerine introductions with propagule size information across multiple regions (New Zealand, Australia, and North America). We excluded species introduced to just one of the three regions or with significant uncertainty in the historical record, as well as species that succeeded or failed in all regions. Because it is often impossible to attribute success to any single event or combination of events, our analysis compared randomly selected propagule sizes of unsuccessful introductions with those of successful introductions. Using Monte Carlo repeated sampling we found no statistical support for the propagule pressure hypothesis, even when using assumptions biased toward showing an effect.

AB The emerald ash borer (EAB) (Agrilus planipennis Fairmaire) (Coleoptera; Buprestidae), is an invasive wood-boring beetle native to northeast Asia. This species was first detected in Michigan USA in 2002, and is a significant threat to native and ornamental ash tree species (Fraxinus spp.) throughout North America. We characterized seven polymorphic microsatellite markers for EAB and used these to investigate EAB population structure in the early invasive populations within North America and in comparison with Asia. We found 2-9 alleles per microsatellite locus, no evidence of linkage disequilibrium, and no association with known coding sequences, suggesting that these markers are suitable for population genetic analysis. Microsatellite population genetic structure was examined in 48 EAB populations sampled between 2003 and 2008 from five regions, three in the introduced range, Michigan (US) and Ontario and Quebec (Canada) and two Asian regions, China and South Korea, where EAB is native. We found significant genetic variation geographically but not temporally in EAB populations. Bayesian clustering analyses of individual microsatellite genotypes showed strong clustering among multiple North American populations and populations in both China and South Korea. Finally, allelic richness and expected heterozygosity were higher in the native range of EAB, but there was no difference in observed heterozygosity, suggesting a significant loss of alleles upon introduction but no significant change in the distribution of alleles within and among individuals.

AB Before implementation of genomic selection, evaluation of the potential accuracy of prediction can be obtained by cross-validation. In this procedure, a population with both phenotypes and genotypes is split into training and validation sets. The prediction model is fitted using the training set, and its accuracy is calculated on the validation set. The degree of genetic relatedness between the training and validation sets may influence the expected accuracy as may the genotype x environment (GxE) interaction in those sets. We developed a method to assess these effects and tested it in cassava (Manihot esculenta Crantz). We used historical phenotypic data available from the International Institute of Tropical Agriculture Genetic Gain trial and performed genotyping by sequencing for these clones. We tested cross-validation sampling schemes preventing the training and validation sets from sharing (i) genetically close clones or (ii) similar evaluation locations. For 19 traits, plot-basis heritabilities ranged from 0.04 to 0.66. The correlation between predicted and observed phenotypes ranged from 0.15 to 0.47. Across traits, predicting for less related clones decreased accuracy from 0 to 0.07, a small but consistent effect. For 17 traits, predicting for different locations decreased accuracy between 0.01 and 0.18. Genomic selection has potential to accelerate gains in cassava and the existing training population should give a reasonable estimate of future prediction accuracies.

TI Analysis of Quantitative Traits in Two Long-Term Randomly Mated Soybean
Populations: I. Genetic Variances
SO CROP SCIENCE

DT Article
ID RECURRENT SELECTION; REGISTRATION; PROGENY; CROSS; YIELD
AB The genetic effects of long-term random mating and natural selection aided by genetic male sterility were evaluated in two soybean [Glycine max (L.) Merr.] populations: RSII and RSIII. Population means, variances, and heritabilities were estimated to determine the effects of 26 generations of random mating. The 10% highest yielding lines from each population were selected. Data was collected on flowering date, maturity date, plant height, lodging score, seed yield, seed weight, protein concentration (PC), and oil concentration (OC). RSII had a mean seed yield, PC, and OC of 2163 kg ha(-1), 416 g kg(-1), and 193 g kg(-1), respectively. Entry-mean heritability for seed yield, PC, and OC was estimated at 36, 68, and 57%, respectively. Theoretical response to selection was 183 kg ha(-1) and, after selection, the realized gain was 161 kg ha(-1). RSIII had a mean seed yield, PC, and OC of 2300 kg ha(-1), 416 g kg(-1), and 190 g kg(-1), respectively. The entry-mean heritability estimates for seed yield, PC, and OC were 57, 87, and 91%, respectively. Theoretical response to selection was 300 kg ha(-1) and, after selection, realized gain was an increase of 139 kg ha(-1). Despite not reaching their theoretical yield potential, the best lines from both populations compared well to check cultivars. The significant genetic variances and heritabilities observed demonstrate that the breakage of linkage blocks by long-term random mating and natural selection were effective in producing competitive lines.

AB Water-use efficiency is often genetically correlated with specific leaf area (SLA) and leaf C isotopic composition (delta C-13) in peanut (Arachis hypogaea L.). The objectives of this study were to examine the effects of environment, genotype, and genotype x environment interaction on SLA, delta C-13, harvest index (HI), and yield and to estimate heritability and the genetic relationships. Fifteen genotypes were tested at two locations with different drought intensities for 2 yr. The additive main effects and multiplicative interaction analysis based on yield data divided eight environments (locations x treatments x years) into four clusters, which reflected a gradient in drought stress, indicating yield trait is a good indication of drought stress. The genotype Exp8-12 was identified as a best drought tolerant germplasm across environments. Heritability estimates for HI (0.68 to 0.89) and delta C-13 (0.75 to 0.89) were higher than those for SLA (0.31 to 0.88) and yield (0.12 to 0.65). A positive but small genetic correlation coefficient (r(g)) (0.26) was found between HI and yield, and low to moderate r(g) (0.14 to 0.55) were observed between HI and SLA. A relative high negative genetic correlation r(g) (-0.81 to -0.57) was found between delta C-13 and yield. In theory, the high heritability and no GxE interaction for delta C-13 make it possible a surrogate that can be used to assess drought tolerance in peanut breeding.

NUTRITION
AB Voluntary intake potential of a forage crop is generally considered to be the most important feed characteristic regulating animal performance. Efforts to develop forage crops with increased intake potential have been associated with reduced plant fitness, prompting a need to modify breeding objectives and methods. The objective of this study was to determine if semihyrids could be used to restore all or a portion of the forage yield lost to drift during selection for low neutral detergent fiber (NDF) in smooth bromegrass (Bromus inermis Leyss.). A total of 48 semihybrids were created by pair crossing within four base (original) populations, four high-NDF populations, and four low-NDF populations. Genetic variation declined progressively with increased NDF concentration. Midparent heterosis was positive and significant for four of six semihybrids at the low-NDF level. Two of these semihybrids also had positive and significant heterosis for NDF, reflecting the typical positive genetic correlation between yield and NDF. However, two of these semihybrids had no heterotic effect for NDF, resulting in partial decay of the genetic correlation due to a combination of linkage and drift acting on alleles that independently control these two traits. Because about one-third of this genetic correlation is malleable by manipulation of linkage and drift, there is potential to produce low-NDF smooth bromegrass populations without sacrificing forage yield potential.

AB The use of crop wild relatives (CWRs) in breeding is likely to continue to intensify as utilization techniques improve and crop adaptation to climate change becomes more pressing. Significant gaps remain in the conservation of these genetic resources. As a first step toward a national strategy for the conservation of CWRs, we present an inventory of taxa occurring in the United States, with suggested prioritization of species based on potential value in crop improvement. We listed 4600 taxa from 985 genera and 194 plant families, including CWRs of potential value via breeding as well as wild species of direct use for food, forage, medicine, herb, ornamental, and/or environmental restoration purposes. United States CWRs are related to a broad range of important food, forage and feed, medicinal, ornamental, and industrial crops. Some potentially valuable species are threatened in the wild, including relatives of sunflower (Helianthus annuus L.), walnut (Juglans regia L.), pepo squash (Cucurbita pepo L.), wild rice (Zizania L.), raspberry (Rubus idaeus L.), and plum (Prunus salicina Lindl.), and few accessions of such taxa are currently conserved ex situ. We prioritize 821 taxa from 69 genera primarily related to major food crops, particularly the approximately 285 native taxa from 30 genera that are most closely related to such crops. Both the urgent collection for ex situ conservation and the management of such taxa in protected areas are warranted, necessitating partnerships between concerned organizations, aligned with regional and global initiatives to conserve and provide access to CWR diversity.

ID F-SP TRITICI; HEXAPLOID WHEAT; GERMPLASM; TAUSCHII; SYSTEM; MAP
AB Wheat leaf rust, caused by Puccinia triticina Eriks., is an important wheat (Triticum aestivum L.) foliar disease worldwide. Growing cultivars incorporating genetic resistance is one of the most effective approaches for disease control. Leaf rust resistance gene Lr42 was identified from a wheat relative, Aegilops tauschii Coss. (goatgrass), and has been transferred into hard winter wheat. A previous study identified two markers closely linked to the gene on the short arm of chromosome 1D (1DS) using a near-isogenic population, but flanking markers for Lr42 were not found. In this study, a new mapping population was developed from a cross between 'KS93U50' (a Lr42 carrier) and a susceptible parent, 'Morocco'. An F-2 population was analyzed with all simple sequence repeat (SSR) markers available from chromosome 1D and F-2 plants and F-3 families were evaluated for seedling resistance to isolate PNMRJ, a rust isolate avirulent to Lr42. The F-2 and F-3 rust data showed that Lr42 was recessive. Seven markers formed the linkage group on chromosome 1DS. The Lr42 region was flanked by two SSR markers, Xwmc432 and Xgdm33, at 18 cM apart. The results confirmed that Lr42 is positioned on the distal end of chromosome 1DS. The flanking markers for Lr42 should be useful for map-based cloning and marker-assisted pyramiding of Lr42 with other leaf rust resistance genes.

AB Increasing interest in deploying multiple types of sensing instruments for agricultural plot-level observations has created a need for simple, high-clearance vehicles that can be easily maneuvered through crops while minimizing damage due to wheel traffic. We describe a simple cart built from a 2-m-wide by 1.2-m-long steel frame that was welded onto two bicycle frames at a height providing 1 m of vertical clearance. Instruments such as radiometers and infrared thermometers are attached to the frame via arms that are secured with U-bolts. A large, horizontal surface allows mounting data loggers, batteries, or computers. The cart is easily maneuvered by one person on level ground or by two persons on terrain with furrows, berms, or other obstacles. Design sketches and lists of materials are provided in an electronic supplement. The basic design is readily modifiable for different interrow spacings and sensor positions.

AB Alleviation of soil-Ca deficiency through gypsum amendment increases the yield potential and ensures high seed quality in peanut (Arachis hypogaea L.). The effects of gypsum treatment, plant life cycle, and the fruit development stages on the accrual of several essential minerals (Ca, S, Mg, P, K, Cu, Ni, Mn, Zn, and Fe) and Na were studied in the pod walls and seeds of two runner cultivars, C-99R and Georgia Green. Calcium concentration was nearly twofold higher in pod walls than in seeds, irrespective of gypsum treatment and cultivar differences. Significant increases in Ca and S, a decrease in P concentration in pod walls and seeds, and a marginal decline in seed-Mg concentration were discernible following gypsum treatment. Sodium concentration decreased in the pod walls and Zn concentration increased in the seeds due to gypsum treatment. Progression in the plant life cycle stage was positively correlated with Ca accrual in both pod walls and seeds. The small-seeded cultivar Georgia Green showed tissue-specific increases in the acquisition of Ca, Mg, and Zn in pod walls and seeds, and a decrease in P concentration in the seeds compared with the large-seeded cv. C-99R. Compared with the respective seed maturation stages, the pod walls had lower S, Mg, P, K, and Zn, and higher Ca, Cu, Ni, Mn, Fe, and Na concentrations. While Ca, S, Mg, P, K, Zn, Fe, and Na concentrations declined, Mn concentration increased in both pod walls and seeds during fruit development.

AB Cultivated sorghum [Sorghum bicolor (L.) Moench subsp. bicolor] can interbreed with a feral weedy relative shattercane [S. bicolor nothosubsp. drummondii (Steud.) de Wet ex Davidse]. Traits introduced from cultivated sorghum could contribute to the invasiveness of a shattercane population. An experiment was conducted to determine the potential for pollen-mediated gene flow from grain sorghum to shattercane. Shattercane with juicy midrib (dd) was planted in soybean [Glycine max (L.) Merr.] fields during 2 yr in concentric arcs at varying distances from a 0.39 ha sorghum pollen source with dry midrib (DD). The arcs were placed so that prevailing winds would carry sorghum pollen to the shattercane. Seven hundred twenty seeds from each of over 300 shattercane panicles in anthesis during sorghum pollen shed each year were collected. Progeny were evaluated by phenotype to determine rate of hybridization. Hybridization averaged 3.6% within the source in 2008 and 16.0% in 2009 and declined as distance increased. Hybridization as high as 2.6% for an individual panicle was measured at the farthest distance evaluated (200 m). Wind direction and speed were also measured and their product affected hybridization rate for all pollination periods. Results indicate that genes from cultivated sorghum will likely be introduced into shattercane populations at distances of at least 200 m and that rate of hybridization is dependent on weather factors such as wind. Source size is also important in determining hybridization rate but was not studied here.

AB Understanding the regulation of net ecosystem exchange and soil C sequestration within pasture systems requires knowledge of its component fluxes, including photosynthetic uptake and respiratory loss. However, little information is available on the partitioning of soil respiration (R-S) between its heterotrophic respiration (R-H) and rhizosphere respiration (R-R) components for perennial cool-season pasture species. The purpose of this study was to use stable C isotopes to examine the effects of regrowth after defoliation on the components of soil respiration for grassland plots planted as an orchardgrass (Dactylis glomerata L.)-white clover (Trifolium repens L.) mixture but dominated by orchardgrass (90 to 100% of harvested biomass). Respiration components were quantified during the first 3 wk following defoliation at the beginning of July in 2010 and 2011. In 2010, R-S, R-H, and R-R were all lowest 1 d after cutting (DAC). Both R-S and R-H significantly increased by 8 DAC but no further increase occurred over the next 2 wk. In contrast, R-R continued to increase throughout the regrowth period. In 2011, R-S did not differ among harvests and averaged across dates was less than in 2010. During the 2011 regrowth period R-H increased slightly whereas R-R did not change significantly. The rhizosphere contribution (R-C) to R-S averaged 0.49, increasing from 0.35 to 0.56 during regrowth in 2010 but decreasing from 0.62 to 0.43 in 2011. Differences among years in respiration responses during regrowth were possibly due to a combination of factors including resource limitations, soil moisture stress, and differences in soil temperature.

AB Mutualistic interactions between ants and Hemiptera are mediated to a large extent by the amount and quality of sugar-rich honeydew produced. Throughout the neotropics, the predaceous fire ant Solenopsis geminata (Fabricius) (Hymenoptera: Formicidae) is found in association with colonies of the pineapple mealybug, Dysmicoccus brevipes (Cockerell) (Hemiptera: Pseudococcidae), which they actively tend and protect from attack by natural enemies. In this study, we evaluate the effects of access to a sucrose solution on the mutualistic association between S.geminata and D.brevipes. Ten colonies of either species were established, with D.brevipes maintained on pumpkin, Cucurbita maxima Duchesne (Cucurbitaceae), in screen cages. Five of the S.geminata colonies were permitted access to vials with 20% sucrose solution and a pumpkin with 20 adult mealybugs. The remaining ant colonies were allowed access to mealybug-infested pumpkins. Ant colonies with access to the sucrose solution attended mealybugs significantly less than those without additional sugar sources. Mealybug survival rates were similar under both treatments. Total body sugars and fructose were nearly twice as high in ants with access to honeydew and sucrose vs. those with access to honeydew and water. Fructose accumulated on the pumpkins over time in both treatments, suggesting that honeydew was not fully exploited by the ants. In conclusion, D.brevipes enjoy lower degrees of ant attendance when S.geminata have alternative sources of carbohydrates. We further discuss the significance of these findings for the conservation of predaceous ants and mealybug biological control.

AB DNA methylation is important for gene regulation and is vulnerable to early-life exposure to environmental contaminants. We found that direct waterborne benzo[a]pyrene (BaP) exposure at 24 mu g/L from 2.5 to 96 hpf to zebrafish embryos significantly decreased global cytosine methylation by 44.8% and promoter methylation in uasa by 17%. Consequently, vasa expression was significantly increased by 33%. In contrast, BaP exposure at environmentally relevant concentrations did not change CpG island methylation or gene expression in cancer genes such as ras-association domain family member 1 (rassf1), telomerase reverse transcriptase (tert), c-jun, and c-myca. Similarly, BaP did not change gene expression of DNA methyltransferase 1 (dnmt1) and glycine N-methyltransferase (gnmt). While total DNMT activity was not affected, GNMT enzyme activity was moderately increased. In summary, BaP is an epigenetic modifier for global and gene specific DNA methylation status in zebrafish larvae. (C) 2013 Elsevier B.V. All rights reserved.

AB Advanced backcross rice lines MIb 4853-9 and 6885-2 harbor major seedling cold tolerance QTL qCTS4 and qCTS12 from the temperate japonica M202 in the genetic background of the indica IR50. Previous studies have shown that these lines exhibit the same tolerance, based on visual ratings, under constant and intermittent exposure to cold stress. However, some differences between the MIb lines with regard to physiological stress indicators are observed under constant exposure and a clear difference is detected using a cold stress recovery assay. Genotyping with over 120 SSR markers did not detect any polymorphisms. Here we report using a reduced representation sequencing method called Restriction Enzyme Site Comparative Analysis to identify M202 introgressions unique to each MIb line as candidate loci for the cold stress recovery trait.

AB Populus tremuloides (trembling aspen) recently experienced extensive crown thinning, branch dieback, and mortality across North America. To investigate the role of climate, we developed a range-wide bioclimate model that characterizes climatic factors controlling distribution of aspen. We also examined indices of moisture stress, insect defoliation and other factors as potential causes of the decline. Historic climate records show that most decline regions experienced exceptionally severe drought preceding the recent episodes. The bioclimate model, driven primarily by maximum summer temperatures and April-September precipitation, shows that decline tended to occur in marginally suitable habitat, and that climatic suitability decreased markedly in the period leading up to decline in almost all decline regions. Other factors, notably multi-year defoliation by tent caterpillars (Malacosoma spp.) and stem damage by fungi and insects, also play a substantial role in decline episodes, and may amplify or prolong the impacts of moisture stress on aspen over large areas. Many severely affected stands have poor regeneration potential, raising concerns that increasing aridity could ultimately lead to widespread loss of aspen forest cover. The analysis indicates that exceptional droughts were a major cause of the decline episodes, especially in the drier regions, and that aspen is sensitive to drought in much of its range. Coupling the bioclimate model with climate projections suggests that we should expect substantial loss of suitable habitat within the current distribution, especially in the USA and Mexico.

AB Water erosion has been considered as the most important worldwide environmental problem, being especially caused by intense rainfall events. The potential of rain to generate soil erosion is known as rainfall erosivity and its estimation is fundamental for the understanding of climatic vulnerability of a given region. This work aims to develop models for estimating mean annual rainfall erosivity for Brazilian regions based on multiple linear regression, using latitude, longitude and altitude as predictors for the models. Equations for rainfall erosivity estimations as function of the Modified Fournier Index (MFI) were acquired from 54 Brazilian pluviographic stations (termed as "Main Stations" in this work) to generate the database for this study. These equations were applied to estimate mean annual rainfall erosivity for 773 different rain gauges taking into account historical series with at least 15 consecutive years of daily precipitation and considering the similarity of the Precipitation Concentration Index (PCI). These rain gauges contain only pluviometric records, thus allowing the rainfall erosivity calculation in function of MFI in accordance with the order of PCI. The goodness-of-fit of each model was evaluated taking into account the adjusted coefficient of determination and the significance level of each variable. Moreover, the mean absolute error, bias of estimation, and the residual probability distribution were evaluated for other 155 rain gauges which were used exclusively for validation. All the adjusted multivariate models presented acceptable values for the statistical coefficients, being possible to estimate the mean annual rainfall erosivity for any location in Brazil using only its geographical coordinates and altitude. An annual rainfall erosivity map was created for Brazil based on the multivariate models and ordinary kriging map for residuals derived from the models (regression-kriging technique). It can be concluded that this map resulted in a spatial distribution of Elm better than the former map and, in addition, it can be considered an important update related to the rainfall erosivity study in Brazil since more representative data sets were used.

AB Host-plant resistance is an effective method for controlling soybean aphid (Aphis glycines Matsumura), the most damaging insect pest of soybean (Glycine max (L.) Merr.) in North America. Recently, resistant soybean lines have been discovered and at least four aphid resistance genes (Rag1, Rag2, Rag3 and rag4) have been mapped on different soybean chromosomes. However, the evolution of new soybean aphid biotypes capable of defeating host-plant resistance conferred by most single genes demonstrates the need for finding germplasm with multigenic resistance to the aphid. This study was conducted to map quantitative trait loci (QTL) for aphid resistance in PI 567324. We identified two major QTL (QTL_13_1 and QTL_13_2) for aphid resistance on soybean chromosome 13 using 184 recombinant inbred lines from a 'Wyandot' x PI 567324 cross. QTL_13_1 was located close to the previously reported Rag2 gene locus, and QTL_13_2 was close to the rag4 locus. A minor QTL (QTL_6_1) was also detected on chromosome 6, where no gene for soybean aphid resistance has been reported so far. These results indicate that PI 567324 possesses oligogenic resistance to the soybean aphid. The molecular markers closely linked to the QTL reported here will be useful for development of cultivars with oligogenic resistance that are expected to provide broader and more durable resistance against soybean aphids compared with cultivars with monogenic resistance.

AB Heligmosomoides bakeri is a nematode with parasitic development exclusively in the small intestine of infected mice that induces a potent STAT6-dependent Th2 immune response. We previously demonstrated that host protective expulsion of adult H. bakeri worms from a challenge infection was delayed in selenium (Se)-deficient mice. In order to explore mechanisms associated with the delayed expulsion, 3-week-old female BALB/c mice were placed on a torula yeast-based diet with or without 0.2 ppm Se, and after 5 weeks, they were inoculated with H. bakeri infective third-stage larvae (L3s). Two weeks after inoculation, the mice were treated with an anthelmintic and then rested, reinoculated with L3s, and evaluated at various times after reinoculation. Analysis of gene expression in parasite-induced cysts and surrounding tissue isolated from the intestine of infected mice showed that the local-tissue Th2 response was decreased in Se-deficient mice compared to that in Se-adequate mice. In addition, adult worms recovered from Se-deficient mice had higher ATP levels than worms from Se-adequate mice, indicating greater metabolic activity in the face of a suboptimal Se-dependent local immune response. Notably, the process of worm expulsion was restored within 2 to 4 days after feeding a Se-adequate diet to Se-deficient mice. Expulsion was associated with an increased local expression of Th2-associated genes in the small intestine, intestinal glutathione peroxidase activity, secreted Relm-beta protein, anti-H. bakeri IgG1 production, and reduced worm fecundity and ATP-dependent metabolic activity.

AB It has been widely reported that colloids can travel faster and over longer distances in natural structured porous media than in uniform structureless media used in laboratory studies. The presence of preferential pathways for colloids in the subsurface environment is of concern because of the increased risks for disease caused by microorganisms and colloid-associated contaminants. This study presents a model for colloid transport in dual-permeability media that includes reversible and irreversible retention of colloids and first-order exchange between the aqueous phases of the two regions. The model may also be used to describe transport of other reactive solutes in dual-permeability media. Analytical solutions for colloid concentrations in aqueous and solid phases were obtained using Laplace transformation and matrix decomposition. The solutions proved convenient to assess the effect of model parameters on the colloid distribution. The analytical model was used to describe effluent concentrations for a bromide tracer and 3.2- or 1-mu m-colloids that were observed after transport through a composite 10-cm long porous medium made up of a cylindrical lens or core of sand and a surrounding matrix with sand of a different grain size. The tracer data were described very well and realistic estimates were obtained for the pore-water velocity in the two flow domains. An accurate description was also achieved for most colloid breakthrough curves. Dispersivity and retention parameters were typically greater for the larger 3.2-mu m-colloids while both reversible and irreversible retention rates tended to be higher for the finer sands than the coarser sand. The relatively small sample size and the complex flow pattern in the composite medium made it difficult to reach definitive conclusions regarding transport parameters for colloid transport.

AB While the eukaryotic genome is the same throughout all somatic cells in an organism, there are specific structures and functions that discern one type of cell from another. These differences are due to the cell's unique gene expression patterns that are determined during cellular differentiation. Interestingly, these cell-specific gene expression patterns can be affected by an organism's environment throughout its lifetime leading to phenotypical changes that have the potential of altering risk of some diseases. Both cell-specific gene expression signatures and environment mediated changes in expression patterns can be explained by a complex network of modifications to the DNA, histone proteins and degree of DNA packaging called epigenetic marks. Several areas of research have formed to study these epigenetic modifications, including DNA methylation, histone modifications, chromatin remodeling and microRNA (miRNA). The original definition of epigenetics incorporates inheritable but reversible phenomena that affect gene expression without altering base pairs. Even though not all of the above listed epigenetic traits have demonstrated heritability, they can all alter gene transcription without modification to the underlying genetic sequence. Because these epigenetic patterns can also be affected by an organism's environment, they serve as an important bridge between life experiences and phenotypes. Epigenetic patterns may change throughout one's lifespan, by an early life experience, environmental exposure or nutritional status. Epigenetic signatures influenced by the environment may determine our appearance, behavior, stress response, disease susceptibility, and even longevity. The interaction between types of epigenetic modifications in response to environmental factors and how environmental cues affect epigenetic patterns will further elucidate how gene transcription can be affectively altered.

AB Epigenetic phenomena are defined as heritable mechanisms that establish and maintain mitotically stable patterns of gene expression without modifying the base sequence of DNA. The major epigenetic features of mammalian cells include DNA methylation, post-translational histone modifications and RNA-based mechanisms including those controlled by small non-coding RNAs (miRNAs). The impact of epigenetic mechanisms in cardiovascular pathophysiology is now emerging as a major player in the interface between genotype to phenotype variability. This topic of research has strict implications on disease development and progression, and opens up possible novel preventive strategies in cardiovascular disease. An important aspect of epigenetic mechanisms is that they are potentially reversible and may be influenced by nutritional-environmental factors and through gene-environment interactions, all of which have an important role in complex, multifactorial diseases such as those affecting the cardiovascular system. Gene expression regulation through the interplay of DNA methylation and histone modifications is well-established, although the knowledge about the function of epigenetic signatures in cardiovascular disease is still largely unexplored. The study of epigenetic markers is, therefore, a very promising frontier of science which may aid in a deeper understanding of molecular mechanisms underlying the modulation of gene expression in the biomolecule pathways linked to cardiovascular diseases.
This review focuses on up-to-date knowledge pertaining to the role of epigenetics, from DNA methylation to miRNAs, in major cardiovascular diseases such as ischemic heart disease, hypertension, heart failure and stroke. (C) 2012 Published by Elsevier Ltd.

AB There is growing interest in broad-scale biodiversity assessments that can serve as benchmarks for identifying ecological change. Genetic tools have been used for such assessments for decades, but spatial sampling considerations have largely been ignored. Here, we demonstrate how intensive sampling efforts across a large geographical scale can influence identification of taxonomic units. We used sequences of mtDNA cytochrome c oxidase subunit 1 and cytochrome b, analysed with maximum parsimony networks, maximum-likelihood trees and genetic distance thresholds, as indicators of biodiversity and species identity among the taxonomically challenging fishes of the genus Cottus in the northern Rocky Mountains, USA. Analyses of concatenated sequences from fish collected in all major watersheds of this area revealed eight groups with species-level differences that were also geographically circumscribed. Only two of these groups, however, were assigned to recognized species, and these two assignments resulted in intraspecific genetic variation (>2.0%) regarded as atypical for individual species. An incomplete inventory of individuals from throughout the geographical ranges of many species represented in public databases, as well as sample misidentification and a poorly developed taxonomy, may have hampered species assignment and discovery. We suspect that genetic assessments based on spatially robust sampling designs will reveal previously unrecognized biodiversity in many other taxa.

AB Ammonia (NH3) volatilized from broiler litter diminishes indoor air quality, which can potentially decrease bird productivity. Emissions of NH3 exhausted from broiler houses pose environmental concerns for ecosystem biodiversity, aquatic nutrient enrichment, and particulate formation in the atmosphere. Research was conducted sampling litter (rice hull base) in 3 tunnel-ventilated commercial broiler houses during wk 3 (mid-growout) of 6 flocks. The purpose was to assess NH3 generated near the sidewalls, waterers, and feeders. Litter samples (100 g) were placed in chambers receiving constant air flow. Boric acid (H3BO3) titration each 24 h for 4 d was used to determine NH3 volatilized from the samples. Litter located near waterers emitted the most cumulative NH3 (approximately 12.3 mg of N.kg of litter(-1).h(-1)) with less NH3 associated with feeders and sidewalls (2.9 to 7.6 mg of N.kg of litter(-1).h(-1)). Moisture content of litter samples was greatest at waterers (45%) followed by sidewalls (26%) and feeders (20%). In addition, litter pH at the sidewalls and feeders could be predicted by linear equations associated with the number of flocks on the litter. At the waterers, litter pH was differentiated based on the half of house where higher litter pH existed in the nonbrood half (8.55 vs. 8.13). The results indicate that controlling NH3 near watering lines to a level consistent with feeding lines and near the house wall could reduce NH3 generated by 38 to 77%. These findings support efforts for NH3 control at mid-growout, especially considering zone litter treatments near waterers and appropriate attention to waterer management.

AB Enrichment of surface waters with excess nutrients is associated with increased algal blooms, euthrophication and hypoxic zones, as reported in the northern Gulf of Mexico. A source of nutrients to surface waters results from fertilizer runoff. Management strategies used to maintain turf on golf courses and recreational fields often include aerification and application of fertilizer. Although research exists on benefits of core cultivation and verticutting (VC) to reduce thatch and the transport of applied chemicals with runoff, there are no studies reporting the effect of coupling these management practices with the goal of further reduction of off-site transport of fertilizer with runoff. We hypothesized that the addition of VC to hollow tine core cultivation (HTCC) would enhance infiltration of precipitation, reduce runoff and nutrient transport with runoff and therefore influence concentrations of nutrients in surface waters receiving runoff from turf managed as a golf course fairway. Greater runoff and mass of soluble phosphorus and ammonium nitrogen transported with runoff were measured from plots managed with HTCC + VC than HTCC; however, the reverse was noted for nitrate nitrogen. Only a portion of the observed trends proved to be statistically significant. Our research showed no reduction or enhancement of risk associated with surface water concentrations of phosphorus or nitrogen, resulting from runoff from creeping bentgrass turf that was managed with HTCC+VC compared to HTCC. Data obtained in this research will be useful to grounds superintendents when selecting best management practices and to scientists seeking data relating runoff to land management for watershed-scale modeling.

DT Article
AB The Heliothinae comprise some of the world's most injurious agricultural pests. This study reanalyses a subsample of the Heliothis group to determine the monophyly of Chloridea (Heliothis virescens and H.subflexa). Two nuclear gene regions, elongation factor-1 (EF-1; 1240bp) and dopa decarboylase (DDC; 687bp), and the barcoding region of mitochondrial cytochrome oxidase I (COI; 708bp) were used in this analysis for a total of 2635bp and a morphological dataset of 20 characters and 62 character states. Sixteen species representing five genera plus two outgroup species were used in the analysis. Analyses used were Maximum Parsimony (MP), Maximum Likelihood (ML) and Bayesian Inference (BI). The revised status for the monophyletic genus Chloridea Duncan and (Westwood) was supported by a very strong bootstrap support (BP=98-100). Larval host-plant usage is discussed within the Heliothis clade. Polyphagy is most likely the ancestral condition with a host shift to monophagy and oligophagy. Based on known larval hosts, Heliocheilus is oligophagous on Poaceae. Traits of host plant use in Helicoverpa and Chloridea where both polyphagy and oligophagy occur in closely related species are discussed.

AB The predominantly Holarctic bee genus Osmia Panzer is species-rich and behaviourally diverse. A robust phylogeny of this genus is important for understanding the evolution of the immense variety of morphological and behavioural traits exhibited by this group. We infer a phylogeny of Osmia using DNA sequence data obtained from three nuclear genes (elongation factor 1-, LW-rhodopsin and CAD) and the mitochondrial gene COI. Our taxon sampling places special attention on North American members of the subgenus Melanosmia Schmiedeknecht; we discuss the novel placement of a number of species traditionally assigned to O. (Melanosmia) and examine the relative support for alternative classifications of this species-rich subgenus. We use this new phylogeny to guide a reassessment of morphological and behavioural characters within Osmia. Our results provide support for the recognition of Osmia (Hapsidosmia), subgen.n., a monotypic subgenus containing Osmia iridis Cockerell & Titus. We synonymize Osmia (Mystacosmia) Snelling under O. (Melanosmia), syn.n. We synonymize Osmia (Acanthosmioides) Ashmead under O. (Melanosmia), syn.n., propose odontogaster species group' as a replacement for the subgeneric name Acanthosmioides, and refine the morphological characters that serve to diagnose the species group. We additionally propose nigrifrons species group' for a clade within O. (Melanosmia) containing most species formerly placed in Osmia (Centrosmia) Robertson. We demonstrate more cohesive patterns of nest substrate use in the nigrifrons and odontogaster species groups than was previously believed to occur, reconsider character polarity of aspects of the female mandible, and show that a large number of morphological characters have evolved convergently within the genus. In order to facilitate discussion of relevant taxa, we propose the following 15 new synonymies: O. bakeri Sandhouse under O. melanopleura Cockerell; O. crenulaticornis Michener under O. pinorum Cockerell; O. claremontensis Michener under O. sedula Sandhouse; O. cockerelli Sandhouse under O. dakotensis Michener; O. francisconis White under O. enixa Sandhouse; O. hurdi White under O. austromaritima Michener; O. sladeni Sandhouse under O. nifoata Cockerell; O. titusi Cockerell under O. phenax Cockerell; O. subtrevoris Cockerell, O. physariae Cockerell, and O. erecta Michener under O. giliarum Cockerell; and O. universitatis Cockerell, O. integrella Cockerell, O. amala Cockerell, and O. metitia Cockerell under O. nigrifrons Cresson, syn.n.

AB Nucleopolyhedroviruses (NPVs) can initiate devastating disease outbreaks in populations of defoliating Lepidoptera, a fact that has been exploited for the purposes of biological control of some pest insects. A key part of the horizontal transmission process of NPVs is the degradation of the larval integument by virus-coded proteins called chitinases, such as V-CHIA produced by the v-chiA genes. We used recombinant and naturally occurring strains of the Lymantria dispar NPV (LdMNPV) to test horizontal transmission in the field, release of virus from dead larvae under laboratory conditions, and cell lysis and virus release in cell culture. In the field, strains of LdMNPV lacking functional v-chiA genes showed reduced horizontal transmission compared to wild-type or repaired strains. These findings were mirrored by a marked reduction in released virus in laboratory tests and cell culture when the same strains were used to infect larvae or cells. Thus, this study tests the pivotal role of liquefaction and the v-chiA gene in field transmission for the first time and uses complementary laboratory data to provide a likely explanation for our findings.

AB Question Is valuable information lost when plant trait group composition is used, rather than species composition, to describe plant community response to range management? Location Elkhead Watershed, Colorado, US. Methods Current model-building efforts use species composition to define changes in ecosystem state, but plant traits may offer a faster and more broadly applicable alternative. We (1) compare states defined by species composition to those defined by trait-based groups of differing complexity and (2) determine how management and environmental site characteristics relate to species- and trait group-defined states. We sampled 72 plots with different grazing and chemical shrub treatment histories on two soil types. We measured plant species composition in each plot and categorized species into trait groups using three classification schemes, which represented increasing numbers of traits and levels of classification complexity. The classifications employed easily measured traits that affect plant response to range management: life form, life history, resprouting ability, height, vegetative reproduction and N-fixation. Using hierarchical cluster analysis, we identified states with similar species or trait group composition. We explored relationships between each set of potential states and management history and environmental factors using logistic regression. Results Trait-based group composition and species composition identified many of the same potential states and responses to grazing and chemical shrub treatment. Relationships between species and trait group composition and management and environmental characteristics differed on the two soil types. Species composition was sensitive to more different management practices, on average, than trait group composition. Trait group composition revealed some relationships to management and environmental drivers that were not detected using species composition. Conclusion This study confirms that species composition is a more sensitive indicator of sagebrush steppe response to range management, and some information is lost with a trait-based approach. However, traits also add to depth of understanding by revealing additional community patterns related to different drivers. Using the most complex trait grouping scheme that is feasible in a particular study, and also looking for patterns based on simpler trait groups, will provide the most complete understanding of sagebrush steppe response to range management.

AB Mycobacterium bovis (M. bovis), the causative agent of bovine tuberculosis, has been identified in nine geographically distinct wildlife populations in North America and Hawaii and is endemic in at least three populations, including members of the Bovidae, Cervidae, and Suidae families. The emergence of M. bovis in North American wildlife poses a serious and growing risk for livestock and human health and for the recreational hunting industry. Experience in many countries, including the USA and Canada, has shown that while M. bovis can be controlled when restricted to livestock species, it is almost impossible to eradicate once it has spread into ecosystems with free-ranging maintenance hosts. Therefore, preventing transmission of M. bovis to wildlife may be the most effective way to mitigate economic and health costs of this bacterial pathogen. Here we review the status of M. bovis infection in wildlife of North America and identify risks for its establishment in uninfected North American wildlife populations where eradication or control would be difficult and costly. We identified four common risk factors associated with establishment of M. bovis in uninfected wildlife populations in North America, (1) commingling of infected cattle with susceptible wildlife, (2) supplemental feeding of wildlife, (3) inadequate surveillance of at-risk wildlife, and (4) unrecognized emergence of alternate wildlife species as successful maintenance hosts. We then propose the use of integrated and adaptive disease management to mitigate these risk factors to prevent establishment of M. bovis in susceptible North American wildlife species.

AB Wildlife reservoir hosts of bovine tuberculosis (bTB) include Eurasian badgers (Meles meles) and brushtail possum (Trichosurus vulpecula) in the UK and New Zealand, respectively. Similar species warrant further investigation in the northern lower peninsula of Michigan, USA due to the continued presence of bTB on cattle farms. Most research in Michigan, USA has focused on interactions between white-tailed deer (Odocoileus virginianus) and cattle (Bos taurus) for the transmission of the infectious agent of bTB, Mycobacterium bovis, due to high deer densities and feeding practices. However, limited data are available on medium-sized mammals such as Virginia opossum (Didelphis virginiana; hereafter referred to as opossum) and their movements and home range in Michigan near cattle farms. We conducted surveillance of medium-sized mammals on previously depopulated cattle farms for presence of M. bovis infections and equipped opossum with Global Positioning System (GPS) technology to assess potential differences in home range between farms inside and outside the bTB core area that has had cattle test positive for M. bovis. On farms inside the bTB core area, prevalence in opossum was comparable [6%, 95% confidence interval (CI) 2.0-11.0] to prevalence in raccoon (Procyon lotor; 4%, 95% CI 1.0-9.0, P=0.439) whereas only a single opossum tested positive for M. bovis on farms outside the bTB core area. The prevalence in opossum occupying farms that had cattle test positive for M. bovis was higher (6.4%) than for opossum occupying farms that never had cattle test positive for M. bovis (0.9%, P=0.01). Mean size of home range for 50% and 95% estimates were similar by sex (P=0.791) both inside or outside the bTB core area (P=0.218). Although surveillance efforts and home range were not assessed on the same farms, opossum use of farms near structures was apparent as was selection for farms over surrounding forested habitats. The use of farms, stored feed, and structures by opossum, their ability to serve as vectors of M. bovis, and their propensity to ingest contaminated sources of M. bovis requires additional research in Michigan, USA.

AB Sorghum is used as bioenergy feedstock, animal feed, and food. Economical methods for disease prevention and control are valuable for producers. Fluorescent Pseudomonas spp. were isolated from sorghum roots and surrounding soil with the goal of finding isolates that significantly inhibited sorghum fungal pathogens. Fluorescent pseudomonads were collected from seedlings of sorghum cultivars RTx433 and Redlan and wheat cultivar Lewjain, grown in two soils. Lewjain is known to support growth of producers of the antibiotic, 2,4-diacetylphloroglucinol (2,4-DAPG). Isolates from all three plants were assessed for hydrogen cyanide (HCN) and extracellular protease production, and for a 2,4-DAPG gene, phlD. Both soil type and plant type affected HCN- and protease-production, but phlD was not affected. Subsets of phlD (+) isolates were chosen to determine phlD genotypes and to conduct in vitro inhibition assays against sorghum pathogens. Most isolates from sorghum and wheat were genotype D, previously associated with superior root colonization. phlD (+) sorghum isolates were co-cultured with five sorghum pathogens. One isolate from each sorghum line exhibited inhibition to all five pathogens but more Redlan isolates were inhibitory to the virulent pathogen, Fusarium thapsinum, than RTx433 isolates. Nearly all inhibitory isolates from either sorghum cultivar were from one soil type. This is consistent with what had been previously observed in field studies: that soil type played a significant role in determining characteristics of fluorescent Pseudomonas spp. isolated from roots or soil, but sorghum genotype also had a considerable effect.

AB Instrumented indentation is a technique that can be used to measure the elastic properties of soft thin films supported on stiffer substrates, including polymer films, cellulosic sheets, and thin layers of biological materials. When measuring thin film properties using indentation, the effect of the substrate must be considered. Most existing models for determining the properties of thin films from indentation measurements were developed for metal and dielectric films bonded to semiconductor substrates and have been applied to systems with film-substrate modulus ratios between 0.1 and 10. In the present work, flat punch indentation of a thin film either bonded to or in contact with a substrate is examined using finite element modeling. A broad range of film-substrate modulus ratios from 0.0001 to 1 are investigated. As the substrate is effectively rigid compared to the film when the film-substrate modulus ratio is less than 0.0001, the results are also useful for understanding systems with lower film-substrate modulus ratios. The effects of the contact radius, film thickness, elastic properties, and friction between the film and the substrate on the measured stiffness were quantified using finite element modeling in order to understand how the elastic properties of the film can be extracted from indentation measurements. A semi-analytical model was developed to describe the finite element modeling results and facilitate the use of the results to analyze experimental measurements. The model was validated through analysis of indentation measurements of thin polyethylene sheets that were supported on substrates of various stiffness.

AB Forest regeneration following disturbance is a key ecological process, influencing forest structure and function, species assemblages, and ecosystem-climate interactions. Climate change may alter forest recovery dynamics or even prevent recovery, triggering feedbacks to the climate system, altering regional biodiversity, and affecting the ecosystem services provided by forests. Multiple lines of evidence - including global-scale patterns in forest recovery dynamics; forest responses to experimental manipulation of CO2, temperature, and precipitation; forest responses to the climate change that has already occurred; ecological theory; and ecosystem and earth system models - all indicate that the dynamics of forest recovery are sensitive to climate. However, synthetic understanding of how atmospheric CO2 and climate shape trajectories of forest recovery is lacking. Here, we review these separate lines of evidence, which together demonstrate that the dynamics of forest recovery are being impacted by increasing atmospheric CO2 and changing climate. Rates of forest recovery generally increase with CO2, temperature, and water availability. Drought reduces growth and live biomass in forests of all ages, having a particularly strong effect on seedling recruitment and survival. Responses of individual trees and whole-forest ecosystems to CO2 and climate manipulations often vary by age, implying that forests of different ages will respond differently to climate change. Furthermore, species within a community typically exhibit differential responses to CO2 and climate, and altered community dynamics can have important consequences for ecosystem function. Age- and species-dependent responses provide a mechanism by which climate change may push some forests past critical thresholds such that they fail to recover to their previous state following disturbance. Altered dynamics of forest recovery will result in positive and negative feedbacks to climate change. Future research on this topic and corresponding improvements to earth system models will be a key to understanding the future of forests and their feedbacks to the climate system.

AB Climate change impacts tree species differentially by exerting unique pressures and altering their suitable habitats. We previously predicted these changes in suitable habitat for current and future climates using a species habitat model (DISTRIB) in the eastern United States. Based on the accuracy of the model, the species assemblages should eventually reflect the new quasi-equilibrium suitable habitats (similar to 2100) after accounting for the lag in colonization. However, it is an open question if and when these newly suitable habitats will be colonized under current fragmented landscapes and realistic migration rates. To evaluate this, we used a spatially explicit cell-based model (SHIFT) that estimates colonization potentials under current fragmented habitats and several estimates of historical migration rates at a 1km resolution. Computation time, which was previously the biggest constraint, was overcome by a novel application of convolution and Fast Fourier Transforms. SHIFT outputs, when intersected with future suitable habitats predicted by DISTRIB, allow assessment of colonization potential under future climates. In this article, we show how our approach can be used to screen multiple tree species for their colonization potentials under climate change. In particular, we use the DISTRIB and SHIFT models in combination to assess if the future dominant forest types in the north will really be dominated by oaks, as modelled via DISTRIB. Even under optimistic scenarios, we conclude that only a small fraction of the suitable habitats of oaks predicted by DISTRIB is likely to be occupied within 100years, and this will be concentrated in the first 10-20km from the current boundary. We also show how DISTRIB and SHIFT can be used to evaluate the potential for assisted migration of vulnerable tree species, and discuss the dynamics of colonization at range limits.

AB The introduction of new crops to agroecosystems can change the chemical composition of the atmosphere by altering the amount and type of plant-derived biogenic volatile organic compounds (BVOCs). BVOCs are produced by plants to aid in defense, pollination, and communication. Once released into the atmosphere, they have the ability to influence its chemical and physical properties. In this study, we compared BVOC emissions from three potential bioenergy crops and estimated their theoretical impacts on bioenergy agroecosystems. The crops chosen were miscanthus (Miscanthusxgiganteus), switchgrass (Panicum virgatum), and an assemblage of prairie species (mix of 28 species). The concentration of BVOCs was different within and above plant canopies. All crops produced higher levels of emissions at the upper canopy level. Miscanthus produced lower amounts of volatiles compared with other grasses. The chemical composition of volatiles differed significantly among plant communities. BVOCs from miscanthus were depleted in terpenoids relative to the other vegetation types. The carbon flux via BVOC emissions, calculated using the flux-gradient method, was significantly higher in the prairie assemblage compared with miscanthus and switchgrass. The BVOC carbon flux was approximately three orders of magnitude lower than the net fluxes of carbon measured over the same fields using eddy covariance systems. Extrapolation of our findings to the landscape scale leads us to suggest that the widespread adoption of bioenergy crops could potentially alter the composition of BVOCs in the atmosphere, thereby influencing its warming potential, the formation of atmospheric particulates, and interactions between plants and arthropods. Our data and projections indicate that, among at least these three potential options for bioenergy production, miscanthus is likely to have lower impacts on atmospheric chemistry and biotic interactions mediated by these volatiles when miscanthus is planted on the landscape scale.

AB This paper presents a new method of assessing the relationship between features of the built environment and obesity, particularly in urban areas. Our empirical application combines georeferenced data on the location of fast-food restaurants with data about personal health, behavioral, and neighborhood characteristics. We define a local food environment' for every individual utilizing buffers around a person's home address. Individual food landscapes are potentially endogenous because of spatial sorting of the population and food outlets, and the body mass index (BMI) values for individuals living close to each other are likely to be spatially correlated because of observed and unobserved individual and neighborhood effects. The potential biases associated with endogeneity and spatial correlation are handled using spatial econometric estimation techniques. Our application provides quantitative estimates of the effect of proximity to fast-food restaurants on obesity in an urban food market. We also present estimates of a policy simulation that focuses on reducing the density of fast-food restaurants in urban areas. In the simulations, we account for spatial heterogeneity in both the policy instruments and individual neighborhoods and find a small effect for the hypothesized relationships between individual BMI values and the density of fast-food restaurants.

AB A classical conditioning approach was used to examine the ability of Culex quinquefasciatus Say (Diptera: Culicidae) to associate odor with a sugar-meal of varying quality. The objectives of this study were to investigate the impact of different sucrose concentrations (5 %, 10 %, or 50 %) on positive response to conditioning and to examine sucrose concentration preference following exposure to a 10 % solution. Mosquitoes conditioned in conjunction with all three sucrose concentrations showed evidence of learning; including the concentration of the conditioning stimulus, and the sex of the mosquito. Using colored solutions to determine feeding patterns of experienced mosquitoes indicated male mosquitoes showed no preference but females showed a preference for 10 % over 5 % sucrose but not between 10 % and 50 % sucrose solutions.

AB Question Seed banks often serve as reservoirs of taxonomic and genetic diversity that buffer plant populations and influence post-disturbance vegetation trajectories; yet evaluating their importance requires understanding how their composition varies within and across spatial and temporal scales (- and -diversity). Shifts in seed bank diversity are strongly governed by the deterministic role of differential seed longevities. Nevertheless, spatio-temporal variability in propagule depletion from and recruitment into seed banks may alter both - and -diversity. Here, we ask to what degree deterministic seed exhaustion, stochasticity in recruitment and mortality, or both, shape - and -diversity? Location Temperate hardwood forest stands of varying ages in northern Pennsylvania, USA. Methods We surveyed the seed bank and herbaceous vegetation communities at 39 sites and examined whether the species richness, abundance and composition of either community differs among and within sites of increasing age ranging from 43 to 106yr old. We explored how -diversity (species richness) and abundance (percentage cover, seed density) varied across the chronosequence age using regression analyses. We analysed differences in -diversity (community composition) using permutational multivariate analyses (i.e. PERMANOVA, PERMDISP). Finally, we tested whether community composition of the herbaceous layer and seed bank communities exhibited nestedness, where nestedness refers to the degree to which less species-rich sites are a non-random subset of more species-rich sites. Results We found seed bank -diversity and abundance consistently declined across a gradient of increasingly older sites. Moreover, nestedness analyses indicated species composition at older sites represented a subset of the species found at younger sites characterized by species with persistent seeds. Nevertheless, seed bank communities demonstrated divergent compositional trajectories, whereby older sites were increasingly dissimilar, not only from younger sites, but also from each other. Conclusions Our results suggest that even in assemblages strongly structured by deterministic forces, such as seed banks, minor stochastic differences in colonization and extinction events may increase -diversity over time. Therefore, we argue deterministic and stochastic processes are complementary factors governing post-disturbance turnover in species assemblages, and suggest that seed banks contribute to species persistence and overall forest community diversity across space and time.

AB Stimulation of plant productivity caused by Agaricus fairy rings has been reported, but little is known about the effects of these fungi on soil aggregation and the microbial community structure, particularly the communities that can bind soil particles. We studied three concentric zones of Agaricus lilaceps fairy rings in Eastern Montana that stimulate western wheatgrass (Pascopyrum smithii): outside the ring (OUT), inside the ring (IN), and stimulated zone adjacent to the fungal fruiting bodies (SZ) to determine (1) soil aggregate proportion and stability, (2) the microbial community composition and the N-acetyl-beta-d-glucosaminidase activity associated with bulk soil at 0-15 cm depth, (3) the predominant culturable bacterial communities that can bind to soil adhering to wheatgrass roots, and (4) the stimulation of wheatgrass production. In bulk soil, macroaggregates (4.75-2.00 and 2.00-0.25 mm) and aggregate stability increased in SZ compared to IN and OUT. The high ratio of fungal to bacteria (fatty acid methyl ester) and N-acetyl-beta-d-glucosaminidase activity in SZ compared to IN and OUT suggest high fungal biomass. A soil sedimentation assay performed on the predominant isolates from root-adhering soil indicated more soil-binding bacteria in SZ than IN and OUT; Pseudomonas fluorescens and Stenotrophomonas maltophilia isolates predominated in SZ, whereas Bacillus spp. isolates predominated in IN and OUT. This study suggests that growth stimulation of wheatgrass in A. lilaceps fairy rings may be attributed to the activity of the fungus by enhancing soil aggregation of bulk soil at 0-15 cm depth and influencing the amount and functionality of specific predominant microbial communities in the wheatgrass root-adhering soil.

AB The study of desiccation tolerance of lichens, and of their chlorobionts in particular, has frequently focused on the antioxidant system that protects the cell against photo-oxidative stress during dehydration/rehydration cycles. In this study, we used proteomic and transcript analyses to assess the changes associated with desiccation in the isolated phycobiont Asterochloris erici. Algae were dried either slowly (5-6h) or rapidly (<60min), and rehydrated after 24h in the desiccated state. To identify proteins that accumulated during the drying or rehydration processes, we employed two-dimensional (2D) difference gel electrophoresis (DIGE) coupled with individual protein identification using trypsin digestion and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Proteomic analyses revealed that desiccation caused an increase in relative abundance of only 11-13 proteins, regardless of drying rate, involved in glycolysis, cellular protection, cytoskeleton, cell cycle, and targeting and degradation. Transcripts of five Hsp90 and two -tubulin genes accumulated primarily at the end of the dehydration process. In addition, transmission electron microscopy (TEM) images indicate that ultrastructural cell injuries, perhaps resulting from physical or mechanical stress rather than metabolic damage, were more intense after rapid dehydration. This occurred with no major change in the proteome. These results suggest that desiccation tolerance of A.erici is achieved by constitutive mechanisms.

AB The circadian clock is an internal timing mechanism that allows plants to make developmental decisions in accordance with environmental conditions. In model plants, circadian clock-associated gigantea (gi) genes are directly involved in control of growth and developmental transitions. The maize gigantea1 (gi1) gene is the more highly expressed of the two gi homeologs, and its function is uncharacterized. To understand the role of gi1 in the regulatory networks of the maize circadian clock system, gi1 mutants were evaluated for changes in flowering time, phase change and growth control. When grown in long-day (LD) photoperiods, gi1 mutants flowered earlier than non-mutant plants, but this difference was not apparent in short-day (SD) photoperiods. Therefore, gi1 participates in a pathway that suppresses flowering in LD photoperiods, but not in SD. Part of the underlying cause of early flowering was up-regulated expression of the FT-like floral activator gene zea mays centroradialis8 (zcn8) and the CONSTANS-like flowering regulatory gene constans of zea mays1 (conz1). gi1 mutants also underwent vegetative phase change earlier and grew taller than non-mutant plants. These findings indicate gi1 has a repressive function in multiple regulatory pathways that govern maize growth and development.

AB Strip tillage is a conservation practice in which narrow strips, generally totaling less than 50% of the field area, are tilled. We hypothesized that strip tillage would be beneficial for long-term soil quality improvement, erosion control, and environmental protection because it also protects crop residues so they can cover and continuously protect the soil surface. A two-year field experiment with three replicates was conducted to quantify effects of three strip widths on selected soil physical properties, seed emergence and yield of sunflower (Helianthus annuus). A powered row crop rotary hoe which is a group of narrow rotary tillers spaced evenly along the width of the toolbar and powered by the tractor power take-off was used to till soil in strips. The rotary hoe was equipped with C-type blades and was used to till strip widths of 37.5, 30 and 22.5 cm by changing the blade position and number of flanges on each row of the rotary hoe. A constant rotor rotational speed (370 rpm), forward tractor speed (5.4 km h(-1)) and tillage depth (10 cm) were used to create the three strip widths that corresponded to tilled zones encompassing 50, 40, and 30% of the field area, respectively. A pneumatic seeder with 75 cm row intervals was used for planting. The results show that as strip width increased, soil temperature increased but soil moisture content decreased due to evaporation loss from the tilled surface of the strips. Sunflower seed emergence ranged from 67 to 93%, with the lowest levels occurring with 22.5 cm strips. Plant length and stalk diameter also increased as strip width increased. Seed yields for the two years also increased with strip width, averaging 4.4, 4.1, and 3.9 Mg ha(-1) for the 37.5, 30 and 22.5 cm strip widths, respectively. Based on these results, although seed yield was least for the 22.5 cm strip width, tractor fuel efficiency was greatest for that width and the soil tended to retain more moisture for that width, compared to the 30 and 37.5 cm widths, so the 22.5 cm strip width is recommended to the eastern Turkey.

AB Management systems influence soil quality over time. A randomized block design in 2 (tillage system) x 3 (crop rotation) factorial arrangement was laid-out to evaluate the impact of tillage and crop rotation (2002-2007) on soil quality. Conventional tillage and No-till were factored into continuous corn, corn-soybean, and corn-soybean-wheat-Cowpea systems. Ten soil cores were collected at 0-7.5, 7.5-15, 15-22.5 and 22.5-30 cm depths and analyzed for biological, chemical and physical parameters. The inductive additive approach was used to calculate biological, chemical, physical and composite soil quality indices. A significant impact of no tillage on different physical chemical and biological parameters was observed. The estimated soil quality index was significantly higher in soil under No-till than conventional tillage. Soil biological quality is a sensitive and consistent indicator of soil quality in response to management practices. (C) 2013 Elsevier B.V. All rights reserved.

AB Production of renewable energy from biomass has been promoted as means to improve greenhouse gas balance in energy production, improve energy security, and provide jobs and income. However, uncertainties remain as to how the agriculture and forest sectors might jointly respond to increased demand for bioelectricity feedstocks and the potential environmental consequences of increased biomass production. We use an economic model to examine how the agriculture and forest sectors might combine to respond to increased demands for bioelectricity under simulated future nationallevel renewable electricity standards. Both sectors are projected to contribute biomass, although energy crops, like switchgrass, produced on agriculture land are projected to be the primary feedstocks. At the highest targets for bioelectricity production, we project increased conversion of forest to agriculture land in support of agriculture biomass production. Although land conversion takes place in response to renewable electricity mandates, we project only minor increases in forest and agriculture emissions. Similarly, crop prices were projected to generally be stable in the face of increased bioelectricity demand and displacement of traditional agriculture crops. (C) 2013 Elsevier Ltd.

AB The original crown-rise model estimates the average height of a crown-base in an even-aged mono-species stand of trees. We have elaborated this model to reduce bias and prediction error, and to also provide crown-base estimates for individual trees. Results for the latter agree with a theory of branch death based on resource availability and allocation. We use the improved model to estimate the growth and stem-profile development of a mean-tree in an even-aged stand of loblolly pine. Predictions show good agreement with data from a loblolly pine spacing trial.

AB Rapidly enhancing oleoresin production in conifer stems through genomic selection and genetic engineering may increase resistance to bark beetles and terpenoid yield for liquid biofuels. We integrated association genetic and genomic prediction analyses of oleoresin flow (g24h-1) using 4854 single nucleotide polymorphisms (SNPs) in expressed genes within a pedigreed population of loblolly pine (Pinus taeda) that was clonally replicated at three sites in the southeastern United States. Additive genetic variation in oleoresin flow (h2 approximate to 0.12-0.30) was strongly correlated between years in which precipitation varied (ra approximate to 0.95), while the genetic correlation between sites declined from 0.8 to 0.37 with increasing differences in soil and climate among sites. A total of 231 SNPs were significantly associated with oleoresin flow, of which 81% were specific to individual sites. SNPs in sequences similar to ethylene signaling proteins, ABC transporters, and diterpenoid hydroxylases were associated with oleoresin flow across sites. Despite this complex genetic architecture, we developed a genomic prediction model to accelerate breeding for enhanced oleoresin flow that is robust to environmental variation. Results imply that breeding could increase oleoresin flow 1.5- to 2.4-fold in one generation.

AB Population genetic and phylogenetic studies have shown that Phaeosphaeria nodorum is a member of a species complex that probably shares its center of origin with wheat (Triticum aestivum and Triticum durum). We examined the evolutionary histories of three known necrotrophic effectors (NEs) produced by P. nodorum and compared them with neutral loci. We screened over 1000 individuals for the presence/absence of each effector and assigned each individual to a multi-effector genotype. Diversity at each NE locus was assessed by sequencing c. 200 individuals for each locus. We found significant differences in effector frequency among populations. We propose that these differences reflect the presence/absence of the corresponding susceptibility gene in wheat cultivars. The population harboring the highest sequence diversity was different for each effector locus and never coincided with populations harboring the highest diversity at neutral loci. Coalescent and phylogenetic analyses showed a discontinuous presence of all three NEs among nine closely related Phaeosphaeria species. Only two of the nine species were found to harbor NEs. We present evidence that the three described NEs of P.nodorum were transmitted to its sister species, Phaeosphaeria avenaria tritici 1, via interspecific hybridization.

AB Global, long-term monitoring of changes in Earth's land surface requires quantitative comparisons of satellite images acquired under widely varying atmospheric conditions. Although physically based estimates of surface reflectance (SR) ultimately provide the most accurate representation of Earth's surface properties, there has never been a globally consistent SR dataset at the spatial resolution (<1 ha) or temporal extent (similar to 40 years) of the Landsat mission. To increase the consistency and robustness of Landsat-based land cover monitoring, we atmospherically corrected the Global Land Survey (GLS) Landsat dataset using the Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) implementation of the Second Simulation of the Satellite Signal in the Solar Spectrum ( 6S) radiative transfer model. The GLS provides synoptic, orthorectified, cloud-free Landsat coverage of Earth's land area in four nominal epochs (1975, 1990, 2000, and 2005). This paper presents the resulting GLS surface reflectance dataset and a global assessment of the 2000- and 2005-epoch data against coincident Moderate Resolution Imaging Spectroradiometer (MODIS) daily SR and Normalized Bidirectional Distribution Function-Adjusted Reflectance (NBAR) measurements. Agreement with respect to MODIS SR and NBAR data is very high, with overall discrepancies (Root-Mean-Squared Deviation (RMSD)) between 1.3 and 2.8 percent reflectance for Landsat-7 Enhanced Thematic Mapper Plus (ELM +) and between 2.2 and 3.5 percent reflectance for Landsat-5 Thematic Mapper (TM). The resulting Landsat surface reflectance dataset and the associated quality metrics for each image are hosted on the Global Land Cover Facility web site for free download (http://www.landcover.org/data/gls_SR). This new repository will provide consistent, calibrated, multi-decadal image data for robust land cover change detection and monitoring across the Earth sciences. (C) 2013 Elsevier Inc.

AB Bird aircraft collisions (bird strikes) are a recognized safety hazard and land uses that attract birds hazardous to aircraft should be avoided on and near airports. Many airfields contain large areas of anthropogenic grassland habitats, often dominated by cool season grasses. Land managed as native warm season grasses (NWSG) potentially could increase bird strike hazards on and near airports by attracting hazardous birds and harboring small mammals that are prey for hazardous raptors. We investigated bird and small mammal communities at three NWSG areas and three adjacent on airfield grassland areas in western Ohio, U. S. A. to determine whether NWSG increased bird strike hazards. Species specific differences in bird abundance and density were evident between the two landcover types, presumably the result of differences in plant community characteristics. Seven species of birds were found exclusively in NWSG or airfield grasslands. Birds of species categorized as 'moderate' to 'extremely high' in regard to hazard (severity) level to aircraft accounted for only 6% and 2% of all birds observed in airfield grasslands and NWSG areas, respectively. Small mammal capture success was approximately three times higher in NWSG areas, although raptor abundance did not differ between the two landcover types. Our findings suggest that NWSG might be considered a viable land use adjacent to airfields; however, similar research at additional locations, including larger NWSG areas, should be conducted.

AB Premise of the study: Microsatellite loci were isolated and characterized from enriched genomic libraries of Artocarpus altilis (breadfruit) and tested in four Artocarpus species and one hybrid. The microsatellite markers provide new tools for further studies in Artocarpus.
Methods and Results: A total of 25 microsatellite loci were evaluated across four Artocarpus species and one hybrid. Twenty-one microsatellite loci were evaluated on A. altilis (241), A. camansi (34), A. mariannensis (15), and A. altilis x mariannensis (64) samples. Nine of those loci plus four additional loci were evaluated on A. heterophyllus (jackfruit, 426) samples. All loci are polymorphic for at least one species. The average number of alleles ranges from two to nine within taxa.
Conclusions: These microsatellite primers will facilitate further studies on the genetic structure and evolutionary and domestication history of Artocarpus species. They will aid in cultivar identification and establishing germplasm conservation strategies for breadfruit and jackfruit.

SO CANADIAN VETERINARY JOURNAL-REVUE VETERINAIRE CANADIENNE
LA English
DT Article
AB This study aimed to identify herd-level risk factors associated with fecal shedding of Shiga toxin-encoding bacteria (STB) on dairy cattle farms in Minnesota, USA. After adjustment for farm size, risk factors included: use of total mixed ration (TMR) for lactating dairy cows [odds ratio (OR) = 3.0; 95% confidence interval (CI): 1.8 to 5.1], no use of monensin for weaned calves (OR = 4.8, 95% CI: 2.5, 9.3), and no use of decoquinate for preweaned calves (OR = 2.2, 95% CI: 1.4, 3.6). Fecal shedding of STB was more common in small herds (< 100 cows, OR = 3.6, 95% CI: 2.1, 6.2) than in large herds (>= 100 cows). Herd management factors related to cattle feeding practices were associated with fecal shedding of STB.

AB There has always been a challenge in manufacturing a sugar free sauce. A basic barbecue sauce formulation was used to make 5 sugar-free preparations combining selected levels of xanthan gum, modified waxy maize starch, sucralose, and acesulfame-K. Physical, chemical, microbial and sensory properties were used to evaluate the product quality. Total Aerobic Plate Count was below detectable limits before and after the incubation period for all 6 products. Total Soluble Solids, water activity and pH -before and after incubation- of the control were significantly different from all 5 sugar-free treatments. Descriptive sensory analysis of prepared products showed that SU treatment (2.0% Starch+ 0.3% Sucralose) exhibited the best in all the sensory properties that were determined compared to all other treatments. One sugar free preparation was significantly more viscous than the control. This study will help producers in formulating a new a sugar free healthy barbecue sauce with properties closely comparable to a sugar containing control formula.

TI RISK TO NATIVE UROLEUCON APHIDS (HEMIPTERA: APHIDIDAE) FROM NON-NATIVE
LADY BEETLES (COLEOPTERA: COCCINELLIDAE)
SO ENTOMOLOGICA AMERICANA
LA English
DT Article
DE non-target effects; native aphids; Coccinella; Hippodamia convergens;
Solidago; Cyclachaena xanthifolia
AB Aphids in the genus Uroleucon Mordvilko (Hemiptera: Aphididae) are native herbivores that feed on goldenrod (Solidago spp.) and other Asteraceae in North America. The aphids are potential prey for a wide variety of natural enemies, including native and non-native species of lady beetles (Coleoptera: Coccinellidae). Non-native lady beetles were introduced to aid control of pest aphids in cropland, but some (e.g. Coccinella septempunctata L. and Harmonia axyridis [Pallas]) are known to prey upon Uroleucon aphids in natural and semi-natural settings, raising concerns about their nontarget effects on native aphids. The objective of this study was to estimate non-target risk to Uroleucon aphids from non-native lady beetles. Risk was estimated by evaluating consumption of Uroleucon aphids by lady beetles in no-choice laboratory tests, and by determining incidence of non-native lady beetles within naturally occurring patches of goldenrod and giant sumpweed (Cyclachaena xanthifolia (Nutt.) Fresen.) used by U. nigrotuberculatum (Olive) and U. ambrosiae (Thomas), respectively, in eastern South Dakota during 2009 and 2011. Although lady beetles substantially lowered populations of Uroleucon aphids in no-choice laboratory tests, they were infrequently associated with natural occurrences of the aphids, with incidence comprised of only four native Hippodamia convergens Guerin-Meneville and one non-native C. septempunctata on 185 aphid-infested sample units in relatively small patches of goldenrod and giant sumpweed. Despite consumption of aphids in laboratory tests, the particularly low incidence of lady beetles in field surveys indicates an empirically small risk of their predation on U. nigrotuberculatum and U. ambrosiae under field conditions.

TI Egg wash wastewater: Estrogenic risk or environmental asset?
SO INTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT
LA English
DT Article
AB Commercial production of eggs and egg products requires the washing of eggs to remove urinary-fecal material and broken egg residue. In the case of one Ohio farming facility, 1.6 million birds produce 1.4 million eggs per day, using approximately 50mL of wash water/egg or approximately 70000L per day. The aqueous waste stream was evaluated for estrogenicity to determine if potential for endocrine disruption would result from agricultural application of such wastewater. Samples collected the Fall (October) of 2010 included: water from 2 egg washers operating in series, inlet pipe to the treatment lagoon, a lagoon composite, and products used within the facility in the cleaning of equipment and treatment of the waste. In February 2011, the treatment lagoon was fitted with an extensive aeration system and subsequent sample sets were collected on 3 consecutive days in May and November. Samples were extracted by solid phase extraction and assayed for estrogenic activity using the in vitro E-Screen assay. Raw untreated wastewater from the egg washers contained 17-estradiol equivalents (E(2)Eqs) ranging from 9 to 18ng/L, pipe grab samples entering into the treatment lagoon ranged from <0.14 to 4.4ng/L (variability related to time of emptying of egg wash tanks), whereas treatment lagoon water contained 0.3 to 4.0ng/L E(2)Eq. Addition of an aeration system to the treatment lagoon eliminated surface frothing, reduced noxious odor emission, and E(2)Eqs were lower than the pre-aeration concentrations (4ng/L [n=1, no statistical comparison possible] vs 0.3 to 1.4ng/L in 2011). Because of matrix effects, estrogens were not quantifiable by LC-MS2 in even egg washwater extracts, at concentrations in which internal deuterated estrogen standards were quantifiable. Estrone and E-2 parent ions were detected in egg washwater samples only, and confirmatory ion fragments were detected in only one of these samples. Estrogenicity of the wastewater from the treatment lagoon was already at the proposed aquatic no effect concentration for 17-E2 and would be expected to decrease further as wastewater passes through 2 consecutive storage ponds before application on field crops for irrigation. The original project plan was to follow the wastewater as it was applied by aerial irrigation and concomitant surface runoff, but based on the consistent and extremely low concentration of estrogenic activity of the wastewater from the treatment lagoon, it was concluded that activity would be below limits of quantitation by E-Screen in water used for irrigation from the storage ponds. Use of egg wash wastewateror gray waterto irrigate crops removes the cost and burden of wastewater treatment by the local wastewater plant, poses little to no potential threat of estrogenic endocrine disruption, and supports the conservation of water resources through the use of wastewater irrigation.

DE alternate bearing; bloom phenology; double kernel; S-allele profile;

AB A field trial was established in the southern San Joaquin Valley to determine yield potential for nine almond selections grown under commercial conditions. Kernel yields were first quantified in 2008 at the end of the third growing season and continued through the 2010 harvest. Harvested tonnage varied significantly, depending on the particular accession, specific field location and harvest year. The almond accessions were genotyped for S-locus alleles, characterized phenologically during bloom, and analyzed for kernel dimensions, pellicle color profiles, nut defects and harvest quality parameters. Bloom duration and overlap of the nine experimental accessions generally coincided with that of 'Nonpareil' during the three examined bloom periods. Analysis of S-alleles revealed semi- or cross-incompatible pairs with some commercial cultivars, and confirmed the self-compatibility status of four of the trialed selections. Harvest year effects were significant on all examined kernel shape and appearance characters as well as all nut defects and harvest quality parameters except for the level of blank and shriveled kernels. Cumulative kernel yield differences and specific character faults have led to the removal of five accessions from the trial after three harvest seasons.

TI OH x F Paternity Perplexes Pear Producers
SO JOURNAL OF THE AMERICAN POMOLOGICAL SOCIETY
LA English
DT Article
AB Early in the 20th century, a collection of fire blight resistant pears from around the world was assembled in southern Oregon in an effort to develop improved rootstocks. 'Old Home' and 'Farmingdale' are two cultivars from Illinois that exhibited strong fire blight resistance and useful horticultural traits. Both became important as interstem stocks and as parents in the development of new rootstocks. In the 1950s, an Oregon nurseryman collected seed from an 'Old Home' tree in British Columbia purportedly pollinated by 'Farmingdale' and hundreds of numbered selections of this cross of 'Old Home' x 'Farmingdale' (OHxF) were evaluated. Several OHxF selections arc now valued as rootstocks worldwide, and 45 unique OH x F selections are maintained at the USDA-ARS National Clonal Germplasm Repository (NCGR), in Corvallis, Oregon. Simple Sequence Repeat (SSR) or microsatellite-based profiles were generated for 'Old Home', 'Farmingdale', 8 OHxF selections, and several reference pear cultivars at NCGR using a standard fingerprinting set developed by the European Cooperative Programme for Plant Genetic Resources. 'Farmingdale' is thought to be a seedling of 'Beurre d'Anjou'. Our study showed that 'Farmingdale' shared at least one SSR allele with 'Anjou' at each locus tested, confirming this parental relationship. Our studies showed that all OHxF selections shared an allele with 'Old Home' at each locus, with one allele carrying a suspected pair of base deletions. However, based on our SSR results, it is impossible for 'Farmingdale' to be the pollen parent for any oldie OHxF selections examined. Evaluation of the world pear collection at NCGR with this fingerprinting set established the cultivar 'Bartlett' as the actual pollen parent of these rootstock clones. Fruit and leaf morphology is also consistent with 'Bartlett' and not 'Farmingdale' as a parent of OHxF rootstock selections. The highly fire blight resistant 'Farmingdale' is apparently very under-represented in the pedigrees of current pear rootstocks, and deserves renewed consideration.

AB Most of the native shrubsteppe habitat in the northern Columbia Basin of eastern Washington has been invaded by cheatgrass (Bromus tectorum) or converted to agricultural lands. Therefore, ecological patterns and dynamics on native shrubsteppe and reestablished grasslands are of high conservation interest. We analyzed the cheek pouch contents of Great Basin pocket mice (Perognathus parvus) from 48 study sites in this region to quantify seed collection by this species and to determine the influence of habitat type on cheek pouch seed contents. In all 3 habitat types-newly established Conservation Reserve Program (CRP) lands, older CRP lands, and shrubsteppe-B. tectorum constituted the majority of seeds collected from the cheek pouches. Mean generic richness of collected seeds was higher in shrubsteppe than in new CRP habitats. On average, females collected a greater number of seed genera than males did, and pocket mice collected more seed genera as the autumn season progressed. Exotic B. tectorum has become the most frequently collected autumn food resource for pocket mice in the northern Columbia Basin.

TI GENETIC SAMPLING OF PALMER'S CHIPMUNKS IN THE SPRING MOUNTAINS, NEVADA
SO WESTERN NORTH AMERICAN NATURALIST
LA English
DT Article
ID EFFECTIVE POPULATION-SIZE; HYBRIDIZATION; SEQUENCES
AB Palmer's chipmunk (Neotamias palmeri) is a medium-sized chipmunk whose range is limited to the higher-elevation areas of the Spring Mountain Range, Nevada. A second chipmunk species, the Panamint chipmunk (Neotamias panamintinus), is more broadly distributed and lives in lower-elevation, primarily pinyon-juniper (Pinus monophylla-Juniperus osteosperma) habitat types. Panamint chipmunks are not closely related to Palmer's, but field identification of the 2 species is unreliable. Palmer's chipmunk is a species of concern in the state of Nevada and is listed by the International Union for Conservation of Nature (IUCN) as endangered. As such, conservation of Palmer's chipmunks is a priority in the Spring Mountains National Recreation Area. We sampled putative Palmer's chipmunks from 13 sites distributed across the Spring Mountains during 2010-2011. We removed Panamint chipmunks by using DNA-based identifications and then analyzed the genetic population structure of Palmer's chipmunks by using a panel of 9 microsatellites. Of the 228 samples that were genotyped, 186 were Palmer's; there was no evidence of hybridization between species. Four sites had exclusively Panamint chipmunks, 5 had exclusively Palmer's chipmunks, and 3 had a mixture of the 2 species. In this study, Palmer's chipmunks were exclusively captured at sites above 2400 m elevation, and Panamint chipmunks were exclusively captured at sites below 2200 m. Panamint chipmunks were trapped in areas typed as pinyon-juniper, but they were also trapped at sites typed as ponderosa pine (Pinus ponderosa) and mixed conifer. Both species were trapped at 3 sites; at all 3 sites, the lower-elevation traps contained Panamint chipmunks and the higher ones Palmer's chipmunks. Population structure within Palmer's chipmunks was minimal: heterozygosity was relatively high, and the populations displayed no signs of recent bottlenecks. Indications are that the distribution of Palmer's chipmunk is limited to higher-elevation areas in the Spring Mountains, but within this area, Palmer's chipmunk occurs as a single, large, well-connected, and stable population.

AVAILABILITY; GENERATION; SIMULATION; PATTERNS
AB Soil evaporation in arid and semi-arid regions is generally moisture-limited. Evaporation in these regions is expected to increase monotonically with increase in precipitation. In contrast, model simulations in a snow-dominated, semi-arid Reynolds Mountain East (RME) watershed point to the existence of an anomalous trend in soil evaporation. Results indicate that soil evaporation in snow-dominated watersheds first increases and then subsequently decreases with increasing precipitation. The anomalous variation is because of two competing evaporation controls: (a) higher soil moisture in wetter years which leads to larger evaporation, and (b) prolonged snow cover period in wetter years which shields the soil from the atmosphere, thus reducing soil evaporation. To further evaluate how the competition is mediated by meteorological and hydrogeological characteristics of the watershed, changes in the trend due to different watershed hydraulic conductivity, vegetation cover, and snowfall area fraction are systematically studied. Results show considerable persistence in the anomalous trend over a wide range of controls. The controlling factors, however, have significant influence both on the magnitude of the WY evaporation and the location of the inflection point in the trend curve. (C) 2013 Elsevier Ltd.

AB Oviposition tendency and subsequent development of the parasitoid wasp Euplectrus platyhypenae Howard was compared using the corn and rice host strains of Spodoptera frugiperda (J. E. Smith) fed corn (Zea mays, 'Truckers Favorite') or stargrass (Cynodon nlemfuensis Vanderyst var. nlemfuensis, 'Florona'). In no-choice and two-choice experiments using newly molted fourth instar hosts, female wasps preferred to oviposit on corn strain larvae fed corn plants. Rice strain larvae were parasitized when fed corn plants, but only after the host had reached an optimal size. This preference might be due to differences in size between host strains at a given stage. No oviposition preference for corn or rice strain larvae fed grass was observed. When female wasps were given a choice between corn and rice strain larvae, they always produced more female offspring on the corn strain than the rice strain larvae, irrespective of the host plant the larvae fed upon. Among rice strain hosts, those fed corn hosted more female offspring than those fed grass. The data also show that host quality had a direct effect on parasitoid size, since larger parasitoid offspring resulted from the largest host fed corn plants, and smaller offspring resulted from the smallest hosts, rice strain larvae fed stargrass. Furthermore, E. platyhypenae larval mortality occurred in hosts of both strains fed stargrass, which may indicate that stargrass allelochemicals are not appropriate for this parasitoid. Implications of these results for biological control methods are discussed.

AB Prior research indicated that earthworms may serve as phoretic hosts to entomopathogenic nematodes. Therefore, we hypothesized that biocontrol efficacy of entomopathogenic nematodes could be enhanced in the presence of earthworms based on increased nematode dispersal through the soil. We also hypothesized that earthworms may serve as phoretic hosts to other entomopathogens, such as entomopathogenic fungi. We tested the first hypothesis by comparing the ability of two strains of Steinernema carpocapsae to suppress the pecan weevil, Curculio caryae, in the presence or absence of the earthworm Lumbricus terrestris. Under greenhouse conditions, S. carpocapsae was applied to the soil surface in pots containing C. caryae larvae. We tested the second hypothesis by determining the effects of L. terrestris on dispersal of the entomopathogenic fungus Beauveria bassiana in soil columns. Our results indicated that earthworm presence improved the ability of S. carpocapsae (Sal strain) to control C. caryae below the soil surface. Additionally, S. carpocapsae (All strain) only caused significant C. caryae suppression relative to the controls in the presence of earthworms. B. bassiana dispersal was enhanced by earthworm presence. The fungus was carried through soil by the earthworm; conidia recovered from the earthworm casts remained viable and was pathogenic to Galleria mellonella. Earthworms and other phoretic hosts may assist in dispersal of entomopathogenic nematode and fungal populations in various ecosystems and thereby assist in regulation of insect pests. Additionally, it may be conceivable to combine the application of earthworms with entomopathogens to achieve enhanced levels of inundative or inoculative biocontrol.

AB Flow and temperature are strongly linked environmental factors driving ecosystem processes in streams. Stream temperature maxima (T (max_w)) and stream flow minima (Q (min)) can create periods of stress for aquatic organisms. In mountainous areas, such as western North America, recent shifts toward an earlier spring peak flow and decreases in low flow during summer/fall have been reported. We hypothesized that an earlier peak flow could be shifting the timing of low flow and leading to a decrease in the interval between T (max_w) and Q (min). We also examined if years with extreme low Q (min) were associated with years of extreme high T (max_w). We tested these hypotheses using long-term data from 22 minimally human-influenced streams for the period 1950-2010. We found trends toward a shorter time lag between T (max_w) and Q (min) over time and a strong negative association between their magnitudes. Our findings show that aquatic biota may be increasingly experiencing narrower time windows to recover or adapt between these extreme events of low flow and high temperature. This study highlights the importance of evaluating multiple environmental drivers to better gage the effects of the recent climate variability in freshwaters.

AB Indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM) are two bioactive compounds from Cruciferous vegetables. The stability of these compounds is a major challenge for their pharmaceutical applications. In this study, zein and zein/carboxymethyl chitosan (CMCS) nanoparticles were prepared to encapsulate I3C and DIM by a combined liquid-liquid phase separation and ionic gelation method. After zein nanoparticles were coated with CMCS, the zeta potential was decreased from around -10 to -20 mV, and encapsulation efficiency was greatly improved. Both nanoparticle formulations provided controlled release of I3C and DIM in PBS medium. Zein and zein/CMCS nanoparticles demonstrated similar protection for both I3C and DIM against ultraviolet (UV) light, attributed mainly to the contribution of the zein protein. Compared with zein nanoparticles, zein/CMCS nanoparticles exhibited better protection of I3C against degradation and better inhibition against its oligomerization to DIM under thermal condition (37 degrees C). Based on our results, the encapsulation of hydrophobic bioactives in zein/CMCS nanoparticles is a promising approach to improve their stability against harsh conditions and provide controlled release for food/pharmaceutical applications.

AB Oats are gaining increasing scientific and public interest for their purported antioxidant-associated health benefits. Most reported studies focused on specific oat extracts or particular oat components, such as beta-glucans, tocols (vitamin E), or avenanthramides. Studies on whole oats with respect to antioxidant and anti-inflammatory activities are still lacking. Here the antioxidant and anti-inflammatory activities from whole oat groats of seven common varieties were evaluated. All oat varieties had very similar oxygen radical absorption capacity compared with other whole grains. In an anti-inflammatory assay, oat variety CDC Dancer inhibited tumor necrosis factor-alpha induced nuclear factor-kappa B activation by 27.5% at 2 mg/ml, whereas variety Deiter showed 13.7% inhibition at a comparable dose. Avenanthramide levels did not correlate with the observed antioxidant and anti-inflammatory activities. Further investigations are needed to pinpoint the specific antioxidant and anti-inflammatory compounds, and potential synergistic and/or matrix effects that may help explain the mechanisms of oat's anti-inflammatory actions.

AB The cholesterol-lowering effects of tomato pomace (TP), tomato seed oil (TS0) and defatted tomato seed (DTS) were determined in male Golden Syrian hamsters. Hamsters fed high-fat diets containing 10% TSO or 18% DTS were compared to a diet containing 10% corn oil and 10% microcrystalline cellulose (control 1), 42% TP were compared to 25% microcrystalline cellulose (control 2). TP, TSO and DTS reduced hepatic total cholesterol (TC) content. DTS also lowered plasma TC and low-density lipoprotein cholesterol (LDLC) concentrations. Fecal excretion of lipid, bile acid and cholesterol increased in the DTS group compared to control 1. DTS-fed hamsters had higher levels of hepatic CYP7A1, CYP51, ABCB11, and ABCG5 gene expression than control, suggesting both hepatic bile acid and cholesterol synthesis increased due to increased fecal excretion of bile acid and cholesterol. The results suggest that protein, dietary fibre or phenolic compounds in DTS may be responsible for plasma cholesterol decrease. Published by Elsevier Ltd.

AB Complete cluster zone leaf removal of 'Pinot noir' was initiated at three separate pre-veraison growth stages (bloom, grain-pea size, and bunch closure) and maintained leaf free until harvest, for four growing seasons (2008-2011). Fruit anthocyanin composition was examined at harvest for the last two vintages (2010 and 2011) and compared to a control-no cluster zone leaf removal. Experiments were conducted at two commercially operating Oregon vineyards (site A = 420 rootstock/'Pinot noir' 115 scion and site B = 3309C rootstock/'Pinot noir' 777 scion). All clusters contained the five anthocyanins typically found in 'Pinot noir'. Leaf removal at bloom and maintained until harvest produced maximum anthocyanin accumulation in 'Pinot noir' grapes (site A = 85.24 mg/100 g and site B = 125.06 mg/100 g), compared to no leaf removal (control: site A = 57.91 mg/100 g and site B = 97.56 mg/100 g). Even leaf removal at bunch closure (last leaf removal initiation period) increased grape anthocyanin (site A 73.22 mg/bog and site B = 118.93 mg/100 g) compared to control, but total anthocyanins were lower than grapes from bloom leaf removal (first time period). Results differed slightly by vineyard site and rootstock/scion combination. Published by Elsevier Ltd.

AB Alkylresorcinols (AR) are phenolic lipids present in the bran of some cereals. AR may serve as a biomarker for whole grain wheat and rye intake. While AR pharmacokinetics and two major metabolites have been reported, the metabolic pathways contributing to their relatively rapid elimination from the circulation remain to be speculative. In this study, we investigated if omega- and beta-oxidation mediate catabolism of the AR homologue C19:0 to form 3,5-dihydroxybenzoic acid and 3-(3,5-dihydroxyphenyl)-1-propanoic acid (DHPPA), using 3 in vitro platforms, human cytochrome P450 4F2 (CYP4F2), human liver S9, and HepG2 cells. One hydroxylated C19:0 metabolite was formed by CYP4F2 and one hydroxylated and one carboxylated C19:0 were tentatively identified after incubation of AR with 59. The formation of DHPPA was quantifiable when HepG2 cells were treated with C19:0 for 48 h. Our results are consistent with a metabolic pathway by which AR are degraded to phenolic acids via CYP4F2-mediated omega-oxidation and subsequent beta-oxidation. 2013 Elsevier Ltd.

AB Alkyl cyanoacrylates have long been used for the synthesis of colloidal nanoparticles. In the involved polymerization reaction, hydroxyl ions derived from dissociation of water have been used as an initiator. In the current research, an animal protein, bovine serum albumin (BSA) molecules were utilized as initiator for the polymerization. Following this reaction scheme, hydrophobic poly(ethyl cyanoacrylate)s were covalently bound to BSA, which is hydrophilic. Therefore, the resultant copolymer was amphiphilic in nature, and formed nanoparticles in the reaction medium. The suspension containing these nanoparticles showed an excellent coating capability on the surface of hydrophobic materials. A simple spray coating changed the wetting property of the material instantly and dramatically. Published by Elsevier B.V.

This study tested the ability of a hand-held VIS hyperspectral imaging system to augment current monitoring methods. Multiple visits were made to two commercial fresh-cut processing facilities. Fluorescence-based detection and automated cycling among three wavelengths, 475, 520, and 675 nm, proved best for detecting a range of anomalies. Numerous deficiencies in existing cleaning protocols were identified. Plant personnel were able to devise changes in the protocols that eliminated most of the detected problems without increasing the net expenditure for cleaning efforts. In addition, imaging identified sites where ATP test results were higher when compared to results for adjacent areas. Published by Elsevier Ltd.

AB Hosting a multi-tier application using an Infrastructure-as-a-Service (IaaS) cloud requires deploying components of the application stack across virtual machines (VMs) to provide the application's infrastructure while considering factors such as scalability, fault tolerance, performance and deployment costs (# of VMs). This paper presents results from an empirical study which investigates implications for application performance and resource requirements (CPU, disk and network) resulting from how multi-tier applications are deployed to IaaS clouds. We investigate the implications of: (1) component placement across VMs, (2) VM memory size, (3) VM hypervisor type (KVM vs. Xen), and (4) VM placement across physical hosts (provisioning variation). All possible deployment configurations for two multi-tier application variants are tested. One application variant was computationally bound by the application middleware, the other bound by geospatial queries. The best performing deployments required as few as 2 VMs, half the number required for VM-level service isolation, demonstrating potential cost savings when components can be consolidated. Resource utilization (CPU time, disk I/O, and network I/O) varied with component deployment location, VM memory allocation, and the hypervisor used (Xen or KVM) demonstrating how application deployment decisions impact required resources. Isolating application components using separate VMs produced performance overhead of similar to 1%-2%. Provisioning variation of VMs across physical hosts produced overhead up to 3%. Relationships between resource utilization and performance were assessed using multiple linear regression to develop a model to predict application deployment performance. Our model explained over 84% of the variance and predicted application performance with mean absolute error of only similar to 0.3 s with CPU time, disk sector reads, and disk sector writes serving as the most powerful predictors of application performance.

AB Cleaning and sanitation in food processing facilities is a critical step in reducing the risk of transfer of pathogenic organisms to food consumed by the public. Current methods to check the effectiveness of sanitation procedures rely on visual observation and sub-sampling tests such as ATP bioluminescence assays and culturing methods. To augment existing verification methods, a hand-held visible hyperspectral imaging device was developed. The device is capable of acquiring reflectance images using ambient lighting, and fluorescence responses to supplemental violet (405 nm) excitation. To enhance the ability of detecting relatively low intensity fluorescence responses in the presence of ambient lighting, the device includes the ability to identify wavebands where the intensity of ambient lighting is relatively low. Valleys in ambient illumination intensity when using fluorescent lighting were found at around 475, 520, 570, and 675 nm. A principal goal is to acquire data to support development of a commercially-viable, hand-held, imaging system. (c) 2013 Elsevier Ltd. All rights reserved.

AB The severity of decay in strawberries stored at either 5 degrees C or 10 degrees C was significantly reduced and the shelf-life was extended by immersing fruits in chitosan solutions of 0.5, 1.0 and 1.5 g/100 mL for 5 min at 20 degrees C as compared to the control. Strawberries treated with chitosan also maintained better fruit quality with higher levels of phenolics, anthocyanins, flavonoids (ellagic acid, ellagic acid glucoside, p-coumaroyl glucose, quercetin 3-glucoside, quercetin 3-glucuronide, kaempferol 3-glucoside, kaempferol 3-glucuronide, cyanidin 3-glucoside, pelargonidin 3-glucoside, cyanidin 3-glucoside-succinate, and pelargonidin 3-glucoside-succinate), antioxidant enzyme activity [catalase (CAT), glutathione-peroxidase (GSH-POD), guaiacol peroxidase (G-POD), dehydroascorbate reductase (DHAR) and monodehydroascorbate reductase (MDAR)], and oxygen radical absorbance capacity for peroxyl radicals (ROO center dot), hydroxyl radical radicals ((OH)-O-center dot; HOSC) and 2,2-Di (4-tert-octylphenyl)-1-picrylhydrazyl (DPPH) than the untreated fruits. Chitosan treatments retarded the decrease of ascorbic acid (ASA) and reduced glutathione (GSH) content and beta-1,3-glucanase activities compared to control. The high contents of antioxidants, antioxidant activity, ASA and GSH and high activity of beta-1,3-glucanase in the treated strawberries reinforced the microbial defense mechanism of the fruit and accentuated the resistance against fungal invasion. Therefore, the application of chitosan coating could be favorable in extending shelf-life, maintaining quality and controlling decay of strawberries. Published by Elsevier Ltd.

AB Fruit fly infestation can be a serious problem in pickling cucumber production. In the United States and many other countries, there is zero tolerance for fruit flies in pickled cucumber products. Currently, processors rely on manual inspection to :detect and remove fruit fly-infested cucumbers, which is labor intensive and also prone to error due to human fatigue and the difficulty of visually detecting infestation that is hidden inside the fruit. In this research, a laboratory hyperspectral imaging system operated in an integrated mode of reflectance and transmittance was used to detect fruit fly-infested pickling cucumbers. Hyperpectral reflectance (450-740 nm) and transmittance (740-1000 nm) images were acquired simultaneously for 329 normal (infestation-free) and fruit fly-infested pickling cucumbers of three size classes with the mean diameters of 16.8, 22.1, and 27.6 mm, respectively. Mean spectra were extracted from the hyperspectral image of each cucumber, and they were then corrected for the fruit size effect using a diameter correction equation. Partial least squares discriminant analyses for the reflectance, transmittance and their combined data were performed for differentiating normal and infested pickling cucumbers. With reflectance mode, the overall classification accuracies for the three size classes and the mixed class were between 82% and 88%, whereas transmittance achieved better classification results with the overall accuracies of 88-93%. Integration of reflectance and transmittance did not result in noticeable improvements, compared to transmittance mode. The hyperspectral imaging system performed better than manual inspection, which had an overall accuracy of 75% and whose performance decreased significantly for smaller size cucumbers. This research demonstrated that hyperspectral imaging is potentially useful for detecting fruit fly-infested pickling cucumbers. Published by Elsevier B.V.

AB Rice straw pellets are the main type of biomass solid fuel and have great potential as a bioenergy resource of the future in China. But it also showed important problems because of its high content of ashes and its low gross calorific value, reducing the possibility to be used in domestic heating. It was certified that mixing different types of biomass materials was helpful to improve the properties of pellets. To improve properties of rice straw pellets and investigate the effect of mixing bamboo and rice straw on the pellet properties, some properties of pellets, manufactured using different mixing ratio of bamboo and rice straw particles, were determined in this research. It can be concluded from this research that physical properties of all pellets meet the requirements of Pellet Fuels Institute Standard Specification for Residential/Commercial Densified except for bulk density of pellets, manufactured using mixing ratio (<= 3:2) of bamboo and rice straw. The inorganic ash and gross calorific value of rice straw pellets cannot meet the requirement of Pellet Fuels Institute Standard Specification for Residential/Commercial Densified (8.0%) and the minimum requirement for making commercial pellets of DIN 51731 (>17,500 J/g). Both properties are improved through mixing bamboo particles and rice straw particles. It is significant that inorganic ash content and gross calorific value of pellets, manufactured using mixing ratio (>= 3:2) of bamboo and rice straw, were lower than 8.0% and higher than 17,500 J/g, respectively. This also shows that mixing different biomass materials is an effective way to optimize properties of biomass solid fuel. All pellets after improvement are proposed as biomass solid fuel and have the potential to be developed as commercial pellets on an industrial scale in China.

AB The paper examines the renewable energy adoption and system size determinants for Californian farmers. We utilize a double-hurdle methodology where system size is determined through a hetero-skedastic ordered binary variable model for four size categories. Our results for system size show that determinants of technology adoption differ from size determinants. For example, environmental practices, Internet connection, and electricity price influence adoption, while, total value of production and acre value impact the size of the installed system. Surprisingly, the price of electricity bears no impact on the size category chosen. Renewable energy adoption and system size have been increasing over time, thus our insights about the interplay of the determinants for adoption and size choice, will assist policy formation.

AB The objective of this work was to optimize a mathematical equation for use as a primary kinetic model that employed a new approach to describe the three-phase growth of bacteria under constant temperature conditions. This research adopted an optimization algorithm in combination with the Runge-Kutta method to solve the differential form of the new growth model in search of an optimized lag phase transition coefficient (LPTC), which is used to define the adaption and duration of lag phases of bacteria prior to exponential growth. Growth curves of Listeria monocytogenes, Escherichia coli O157:H7, and Clostridium perfringens, selected from previously published data, were analyzed to obtain an optimized LPTC for each growth curve and a global LPTC for all growth curves. With the new optimized LPTC, the new growth model could be used to accurately describe the bacterial growth curves with three distinctive phases (lag, exponential, and stationary). The new optimized LPTC significantly improved the performance and applicability of the new model. The results of statistical analysis (ANOVA) suggested that the new growth model performed equally well with the Baranyi model. It can be used as an alternative primary model for bacterial growth if the bacterial adaption is more significant in controlling the lag phase development. Published by Elsevier Ltd.

AB Since the first isolation of Rift Valley fever virus (RVFV) in the 1930s, there have been multiple epizootics and epidemics in animals and humans in sub-Saharan Africa. Prospective climate-based models have recently been developed that flag areas at risk of RVFV transmission in endemic regions based on key environmental indicators that precede Rift Valley fever (RVF) epizootics and epidemics. Although the timing and locations of human case data from the 2006-2007 RVF outbreak in Kenya have been compared to risk zones flagged by the model, seroprevalence of RVF antibodies in wildlife has not yet been analyzed in light of temporal and spatial predictions of RVF activity. Primarily wild ungulate serum samples from periods before, during, and after the 2006-2007 RVF epizootic were analyzed for the presence of RVFV IgM and/or IgG antibody. Results show an increase in RVF seropositivity from samples collected in 2007 (31.8%), compared to antibody prevalence observed from 2000-2006 (3.3%). After the epizootic, average RVF seropositivity diminished to 5% in samples collected from 2008-2009. Overlaying maps of modeled RVF risk assessments with sampling locations indicated positive RVF serology in several species of wild ungulate in or near areas flagged as being at risk for RVF. Our results establish the need to continue and expand sero-surveillance of wildlife species Kenya and elsewhere in the Horn of Africa to further calibrate and improve the RVF risk model, and better understand the dynamics of RVFV transmission.

In order to investigate the physiological role of this interaction, we examined expression and localization of SPCA2 and Orai1 in mouse lactating mammary glands. We observed co-induction and co-immunoprecipitation of both proteins, and isoform-specific differences in the localization of SPCA1 and SPCA2. Three-dimensional cultures of normal mouse mammary epithelial cells were established using lactogenic hormones and basement membrane. The mammospheres displayed elevated Ca2+ influx by store independent mechanisms, consistent with upregulation of both SPCA2 and Orai1. Knockdown of either SPCA2 or Orai1 severely depleted Ca2+ influx and interfered with mammosphere differentiation. We show that SPCA2 is required for plasma membrane trafficking of Orai1 in mouse mammary epithelial cells and that this function can be replaced, at least in part, by a membrane-anchored C-terminal domain of SPCA2. These findings clearly show that SPCA2 and Orai1 function together to regulate Store-independent Ca2+ entry (SICE), which mediates the massive basolateral Ca2+ influx into mammary epithelia to support the large calcium transport requirements for milk secretion.

AB The gastrointestinal tract is populated by an array of microbial species that play an important role in metabolic and immune functions. The composition of microorganisms is influenced by the components of the host's diet and can impact health. In the present study, dietary enrichment of lowbush wild blueberries (LWB) was examined to determine their effect on colon microbial composition and their potential in promoting gut health. The microbial composition and functional potential of the colon microbiota from Sprague Dawley rats fed control diets (AIN93) and LWB-enriched diets (AIN93+8% LWB powder substituting for dextrose) for 6 weeks were assessed using Illumina shotgun sequencing and bioinformatics tools. Our analysis revealed an alteration in the relative abundance of 3 phyla and 22 genera as representing approximately 14 and 8% of all phyla and genera identified, respectively. The LWB-enriched diet resulted in a significant reduction in the relative abundance of the genera Lactobacillus and Enterococcus. In addition, hierarchal analysis revealed a significant increase in the relative abundance of the phylum Actinobacteria, the order Actinomycetales, and several novel genera under the family Bifidobacteriaceae and Coriobacteriaceae, in the LWB group. Functional annotation of the shotgun sequences suggested that approximately 9% of the 4709 Kyoto Encyclopaedia of Gene and Genome (KEGG) hits identified were impacted by the LWB-diet. Open Reading Frames (ORFs) assigned to KEGG category xenobiotics biodegradation and metabolism were significantly greater in the LWB-enriched diet compared to the control and included the pathway for benzoate degradation [PATH:ko00362] and glycosaminoglycan degradation [PATH:ko00531]. Moreover, the number of ORFs assigned to the bacterial invasion of epithelial cells [PATH:ko05100] pathway was approximately 8 fold lower in the LWB group compared to controls. This study demonstrated that LWBs have the potential to promote gut health and can aid in the development of optimal diets.

AB In West Alabama, disease outbreaks in 2009 caused by Aeromonas hydrophila have led to an estimated loss of more than $3 million. In 2010, disease outbreak occurred again in West Alabama, causing losses of hundreds of thousands of pounds of market size channel catfish. During the 2010 disease outbreak in West Alabama, four isolates of A. hydrophila were cultured from the kidney tissues of diseased channel catfish. Both analytical profile index (API) 20 E biochemical tests and 16S-23S rRNA sequencing results confirmed the four isolates as A. hydrophila. Virulence studies revealed that the four isolates were highly virulent to channel catfish by intraperitoneal injection, with LD50 value of similar to 1.3 x 10(5) CFU/fish. Extracellular proteins (ECPs) of A. hydrophila are well known to be toxic to fish. Therefore, ECPs of the four 2010 West Alabama isolates of A. hydrophila were characterized in this study. The ECPs of the four 2010 isolates were found to be toxic to channel catfish fingerlings, with LD50 value of 16 mu g/fish. Thirty ECP fractions were obtained from the ECPs of the 2010 isolates of A. hydrophila by cation-exchange chromatography, of which nine fractions were found to be toxic to catfish gill cells and channel catfish fingerlings. Mass spectrometry identified 228 proteins from the nine toxic fractions, of which 23 were shared by toxic fractions, including well known virulence factors such as hemolysin, aerolysin, elastase (metalloprotease), nuclease, and 5'-nucleotidase. Hemolytic activity, protease activity, and nuclease activity of the four isolates were found to be significantly (P < 0.05) higher than that of a reference A. hydrophila strain AL98-C1B. Our results might shed light on the possible virulence factors of the highly virulent West Alabama isolates of A. hydrophila. Published by Elsevier B.V.
