The study was conducted in eighteen 0.5 ha plots following three consecutive years of treatment: six plots intensively grazed in summer, six in winter, and six not grazed. There was no difference in perennial grass cover on the summer-grazed and winter-grazed plots. Intensive seasonal grazing had no effect on the abundance and community composition of soil microarthropods. Within each plot there were six subplots: summer rain-out, winter rain-out, burned, glucose amendment, rain-out control and burn-glucose control. Fire and carbon enrichment had no significant effect on soil microarthropod abundance or community composition. The average number of microarthropods ranged from 8915 plus or minus 1422 m-2 in the ungrazed, unburned plots to 7175 plus or minus 1232 m-2 in the winter-grazed, unburned plots. Microarthropod densities in the glucose-amended plots were 8917 plus or minus 4902 m-2 in the winter-grazed plots and 10,731 plus or minus 863 m-2 in the glucose-amended, summer-grazed subplots. The prostigamatid mite, Tydeus sp., was the most abundant microarthropod taxon in all treatment plots.

After irradiation, the samples were stored for 14 days at 4 degree C. O(2) levels in the packages of fresh-cut Iceberg lettuce decreased and CO(2) levels increased with increasing radiation dose, suggesting that irradiation increased respiration rates of lettuce. Tissue browning of irradiated cut lettuce was less severe than that of non-irradiated, probably due to the lower O(2) levels in the packages. However, samples irradiated at 3 and 4 kGy had lower maximum force and more severe sogginess than the non-irradiated control. In addition, ascorbic acid content of irradiated lettuce was 22-40% lower than the non-irradiated samples after 14 days of storage. The visual appearance of spinach was not affected by irradiation even at a dose of 4 kGy. Consumer acceptance suggested that more people would dislike and would not buy spinach that was treated at 3 and 4 kGy as compared to the non-irradiated sample. Overall, irradiation at doses of 1 and 2 kGy may be employed to enhance microbial safety of fresh-cut Iceberg lettuce and spinach while maintaining quality.

Rabies managers in the United States Department of Agriculture (USDA) have applied a simple raccoon (Procyon lotor) abundance index (RAI) based on cumulative catch of unique raccoons per unit area to determine vaccine-bait distribution densities. This approach was designed to allow for both the collection of biological samples and to index raccoon abundance to determine bait densities for oral rabies programs. However, post-baiting surveillance data indicate that, on average, only 30% of raccoons sampled have vaccine induced rabies antibody titers, suggesting that bait densities may not be well calibrated to raccoon densities. We trapped raccoons using both capture-mark-recapture (CMR) and the standard RAI to evaluate the accuracy of the current index-based methodology for estimating raccoon density. We then developed a resource selection function from spatial data collected from radio-collared raccoons to standardize trap placement within the existing RAI protocol, and evaluated the performance of this modified RAI approach relative to CMR for estimating raccoon population size. Both abundance and density estimates derived using the RAI consistently underestimated raccoon population sizes compared with CMR methods. Similarly, although the use of resource selection models to inform trap placement appeared to improve the accuracy of the RAI, the effectiveness of this method was inconsistent because of an inability to account for variance in detection probabilities. Despite the logistical advantages of using indices to estimate population parameters to determine vaccine bait distribution densities, our results suggest that adjustments may be necessary to more accurately quantify raccoon abundance, which should improve the effectiveness of rabies management in the United States. In particular, estimates of detection probabilities are needed to more precisely quantify abundance estimates and ensure appropriate vaccine coverage rates. [copy 2012 The Wildlife Society.

Attack by multiple enemies may give rise to indirect interactions, the nature of which may be influenced by the abiotic environment. We conducted a field experiment to determine (1) whether indirect interactions arose between Centaurea solstitialis, a foliar pathogen and three insect seed predators and (2) how the outcome was influenced by soil type (serpentine and non-serpentine). Because serpentine soils support high numbers of endemic species they are a priority for conservation. They also have very low calcium concentrations and Ca super(++) regulates plants' ability to defend against pathogen infection. C. solstitialis growing on serpentine soil may therefore be more vulnerable to the pathogen and this may in turn affect the plant's subsequent interactions with seed predators. We found that pathogen infection had a direct, negative impact on plant performance but its impact was not greater on serpentine plants. When attacked by the seed predators, inflorescences produced more viable seed when they were on plants infected with the pathogen than when they were on uninfected plants and the data suggest that this reflects reductions in larval seed-feeding. On the non-serpentine soil, the pathogen's direct, negative impact was entirely canceled out by its indirect, positive effect via reduced seed predation. On the serpentine soil, plants attacked by the pathogen and the insect seed predators produced half as many seeds than plants attacked only by the seed predators. Our results demonstrate that biocontrol agent interactions may be modified by the plant and by the abiotic environment in a way that fundamentally alters their net impact on the weed.

In this study, biochars produced from five manure varieties (dairy, paved feedlot, swine solids, poultry litter, and turkey litter) at two pyrolytic temperatures (350 and 700 degrees C) were examined for the stabilization of Pb, Cu, Ni, and Cd in a weathered, acidic Norfolk loamy sand (fine-loamy, kaolinitic, thermic, Typic Kandiudult). Equilibrium concentrations in the aqueous phase were determined for heavy metals (Cu, Ni, Cd, and Pb) and additional selected elements (Na, P, S, Ca, Mg, Al, and K); these were analyzed by positive matrix factorization to quantitatively determine the factors responsible for the biochar's ability to bind the selected heavy metals in soil. Concurrently with the greatest increase in pH and highest equilibrium Na, S, and K concentrations, poultry litter, turkey litter, and feedlot 700 degrees C biochar exhibited the greatest heavy metal retention. In contrast, manure varieties containing disproportionately high (swine) and low (dairy) ash, P, and other elements were the least effective stabilizers. Regardless of the manure type, proton nuclear magnetic resonance analyses showed the removal of leachable aliphatic and nitrogen-containing heteroaromatic functional groups at the higher (700 degrees C) pyrolysis temperature. Consistently greater Cu retention by the 700 degrees C biochar indicated the mobilization of Cu by 350 degrees C biochar-born dissolved organic carbon; however, the influence of other temperature-dependent biochar characteristics cannot be ruled out.

The commercial X-ray irradiation facility, Hawaii Pride LLC, has been shipping papaya and other tropical fruits and vegetables to the United States mainland using irradiation for 11 years. Irradiation is an approved treatment to control quarantine pests in 17 fruits and 7 vegetables for export from Hawaii to the US mainland. Hawaiian purple sweet potato is the highest volume product with annual exports of more than 12 million lbs (55001). The advent of generic radiation treatments for tephritid fruit flies (150 Gy) and other insects (400 Gy) will accelerate commodity export approvals and facilitate worldwide adoption. Lowering doses for specific pests and commodities can lower treatment costs and increase capacity owing to shorter treatment times, and will minimize any quality problems. Current impediments to wider adoption include the 1 kGy limit for fresh horticultural products, the labeling requirement, and non-acceptance of phytosanitary irradiation in Japan, the European Union, and elsewhere. Irradiation has potential as a treatment for unregulated imports to prevent new pest incursions.

This growth factor isoform contains exon 7, which is essential for binding to extracellular domain of VEGF receptor 2, located on endothelial cells lining the surface of blood vessels. This binding stimulates the cascade of downstream signalling events leading to process known as angiogenesis. hVEGF sub(165) overexpressed with His-tag in BL21 E. coli cells forms inclusion bodies (insoluble protein), so the research found the procedure for its solubilization and purification on a Nickel based affinity chromatography. Although this eukaryotic signal protein needs posttranslational processing for its full function as a homodimer, author verified the biological activity of our hVEGF sub(165) protein, obtained as monomer, by wound healing test.

Several of the larger river systems in the upland portion of the Yazoo River Basin have subjected channelization resulting in profound changes in the physical and geomorphological characteristics of these systems. Fish were sampled using electroshocking gear and hoop nets to evaluate the impact of stream bank destabilization and loss of habitat heterogeneity resulting from channelization on fish communities. While distinct differences in the fish communities were evident, only the Skuna appeared to have characteristics of a damaged system. More than 95% of the biomass was comprised of species reaching an adult length of less than 300 mm. The lotic omnivorous fishes that dominated the biomass from Skuna are often associated with smaller streams rather than rivers. Furthermore, 72% of the catch consisted of fish preferring littoral zone habitats. The shallow depth and lack of woody debris in Skuna provided a selective advantage for smaller species of fish that could use shoreline habitats as protection from the current. Based on results from the Skuna River, channel straightening that leads to channel incision, bank failure and over widening provide habitats too shallow to support a community of fishes typical of northern Mississippi riverine system. This information may be useful in making comparison of damaged riverine ecosystems and assist managers in determining impairment and success in the TMDL (Total Maximum Daily Load) process.

Results showed that stirred-tank bioreactors can be used to mass produce stable MS of Metarhizium and that culturing and drying protocols significantly affected MS yield and stability. Length of fermentation (4-7 days) for Metarhizium cultures had no significant impact on biomass accumulation, MS formation or the storage stability of the air-dried MS granules. Although cultures of Metarhizium grown on media with a carbon-to-nitrogen (C:N) ratio of 30:1 produced significantly more biomass when compared to cultures grown in media with a C:N ratio of 50:1, MS formation and desiccation tolerance following drying were similar. After storage for 1 year at 4 degree C, conidia production by air-dried MS granules from 50:1 media was significantly higher compared to MS granules from 30:1 media. The addition of diatomaceous earth (DE) to cultures of Metarhizium prior to drying at rates of 0-60 g L super(-1) had no significant effect on MS desiccation tolerance but did impact conidia production. Air-dried MS granules without DE produced significantly more conidia g super(-1) during the first 4 months of storage, but after 1 year, conidia production was similar regardless of DE content of the MS granule. Microsclerotial granules with higher moisture levels (2.6-5.0% w/w) produced significantly more conidia immediately after drying and MS granules with low moisture (0-2.5% w/w) produced more conidia after 12 months storage.

Two field blocks with two different soil types, Belk clay (BaA) and Ships clay (ShA), were set up with cotton, corn, soybean, and sorghum in each block and grown using conventional production practices for the area. Spectral information was collected from all crops at different growth stages from May to July 2009. Reflectance spectra and the first derivative of the spectra were analyzed to characterize the spectral properties of crop types and compare the crops grown in different soil types. The red-edge points of cotton, soybean, and sorghum shifted with the growth stage. Principal component analyses were successful in reducing the dimensionality of the hyper-spectral data and identifying significant features from the original data. Most significant wavelengths selected were in the 548-556 nm, 679-682 nm, 756-764 nm, and 928-940 nm regions of the spectrum.

KINEROS was one of the first widely available watershed models that interactively coupled a finite difference approximation of the kinematic overland flow equations to a physically based infiltration model. Development and improvement of KINEROS continued from the 1960s on a variety of projects for a range of purposes, which has resulted in a suite of KINEROS-based modeling tools. This article focuses on KINEROS2 (K2), a spatially distributed, event-based watershed rainfall-runoff and erosion model, and the companion ArcGIS-based Automated Geospatial Watershed Assessment (AGWA) tool. AGWA automates the time-consuming tasks of watershed delineation into distributed model elements and initial parameterization of these elements using commonly available, national GIS data layers. A variety of approaches have been used to calibrate and validate K2 successfully across a relatively broad range of applications (e.g., urbanization, pre- and post-fire, hillslope erosion, erosion from roads, runoff and recharge, and manure transport). The case studies presented in this article (1) compare lumped to stepwise calibration and validation of runoff and sediment at plot, hillslope, and small watershed scales; and (2) demonstrate an uncalibrated application to address relative change in watershed response to wildfire.

Several calibration techniques have been developed for SWAT, including manual calibration procedures and automated procedures using the shuffled complex evolution method and other common methods. In addition, SWAT-CUP was recently developed and provides a decision-making framework that incorporates a semi-automated approach (SUFI2) using both manual and automated calibration and incorporating sensitivity and uncertainty analysis. In SWAT-CUP, users can manually adjust parameters and ranges iteratively between autocalibration runs. Parameter sensitivity analysis helps focus the calibration and uncertainty analysis and is used to provide statistics for goodness-of-fit. The user interaction or manual component of the SWAT-CUP calibration forces the user to obtain a better understanding of the overall hydrologic processes (e.g., baseflow ratios, ET, sediment sources and sinks, crop yields, and nutrient balances) and of parameter sensitivity. It is important for future calibration developments to spatially account for hydrologic processes; improve model run time efficiency; include the impact of uncertainty in the conceptual model, model parameters, and measured variables used in calibration; and assist users in checking for model errors. When calibrating a physically based model like SWAT, it is important to remember that all model input parameters must be kept within a realistic uncertainty range and that no automatic procedure can substitute for actual physical knowledge of the watershed.

Although it is a one-dimensional model, it has many desirable features for the modeling community. This article outlines the principles of calibrating the model component by component with one or more datasets and validating the model with independent datasets. Users should consult the RZWQM2 user manual distributed along with the model and a more detailed protocol on how to calibrate RZWQM2 provided in a book chapter. Two case studies (or examples) are included in this article. One is from an irrigated maize study in Colorado to illustrate the use of field and laboratory measured soil hydraulic properties on simulated soil water and crop production. It also demonstrates the interaction between soil and plant parameters in simulated plant responses to water stresses. The other is from a maize-soybean rotation study in Iowa to show a manual calibration of the model for crop yield, soil water, and N leaching in tile-drained soils. Although the commonly used trial-and-error calibration method works well for experienced users, as shown in the second example, an automated calibration procedure is more objective, as shown in the first example. Furthermore, the incorporation of the Parameter Estimation Software (PEST) into RZWQM2 made the calibration of the model more efficient than a grid (ordered) search of model parameters. In addition, PEST provides sensitivity and uncertainty analyses that should help users in selecting the right parameters to calibrate.

Three calibration approaches are presented and compared for simulating soil water content. Approaches included a stepwise local search methodology, trial-and-error calibration, and an automated multi-objective parameter optimization algorithm; the automated algorithm was used to optimize four separate parameter sets with increasing vertical heterogeneity in the soil profile, i.e., considering from one to four soil layers, respectively, within the soil profile. In the stepwise approach, parameters for each soil horizon were individually varied to determine which parameter could minimize the root mean square deviation (RMSD) between measured and simulated soil water content of the top 20 cm. Subsequently, all other parameters were varied while holding constant the parameter that minimized the RMSD in the previous iteration. Iterations continued until the RMSD was minimized. For the trial-and-error calibration, plots of simulated and measured soil water content were examined, and soil parameters of each soil horizon or individual soil layers were varied to obtain a better fit and to minimize RMSD of the top 20 cm as well as the top 60 cm. The automated multi-objective parameter optimization algorithm searched throughout a feasible parameter space for parameter combinations that minimized each of several RMSD objective functions, and then effectively minimized the tradeoffs between the objective functions. Variation in simulated daily soil water content between the simulations ranged from 0.018 to 0.026 m(3) m(-3) at the different depths, with more variability between simulations being observed within the top 10 cm. Much of the variability between the calibrated simulations was attributed to the calibrations that assumed uniform properties in the 0-75 cm soil horizon, i.e., the stepwise calibration and the single-layer automated optimization; variation between these and the other simulations ranged as high as 0.030 to 0.043 m(3) m(-3) near the surface. Advantages and disadvantages of the three calibration approaches are discussed.

Entrepreneurship may thus be more attractive in areas featuring high employment risk and/or low returns. This research contributes to the existing regional employment portfolio literature by using more disaggregated data at both the county and the commuting zone levels. Commuting zones in particular represent a broader spectrum of labor market agglomerations across both rural and urban areas to provide the most stringent and revealing tests of the interrelationship between local employment portfolios and the choice to pursue entrepreneurship. The authors find a U-shaped risk/return trade-off using employment variance and growth, consistent with the literature. They test their hypothesis with a model of regional entrepreneurship, incorporating the employment portfolio variables. This is the first known study to explore the hypothesized relationship between wage and salary employment portfolios and entrepreneurship, effectively synthesizing two previously disparate literatures.

This article introduces a special collection of 22 research articles that present and discuss calibration and validation concepts in detail for 25 hydrologic and water quality models. The main objective of this introductory article is to introduce and summarize key aspects of the hydrologic and water quality models presented in this collection. The models range from field to watershed scales for simulating hydrology, sediment, nutrients, bacteria, and pesticides at temporal scales varying from hourly to annually. Individually, the articles provide model practitioners with detailed, model-specific guidance on model calibration, validation, and use. Collectively, the articles in this collection present a consistent framework of information that will facilitate development of a proposed set of ASABE model calibration and validation guidelines.

This study investigated the variation in frequency distributions of storm initiation time (SI time) within a day due to elevation changes and month. Actual storms without 24 h constraints were used, as opposed to simply bursts of precipitation within a 24 h period. Two methods of characterizing and quantifying these distributions were investigated: kernel density estimation (KDE), and a mixed doubly truncated normal (MDTN) distribution method using nonlinear curve fitting subject to bounds on the parameters. Parameter estimation methods were also investigated. Data came from the raingauge network maintained by the USDA-ARS at the Reynolds Creek Experimental Watershed in southwest Idaho over a 982 m elevation gradient. There was no difference between frequency distributions of SI time with elevation or precipitation type over the 147 km(2) study area. There was a significant shift in Si-time distribution from earlier in the morning in late fall and winter to early afternoon during the spring and summer. Both the KDE and MDTN methods accurately characterized the observed histograms, which included near-uniform, single-mode, and bimodal distributions. The MDTN method worked well most of the time (-97%) but can have mathematical convergence problems. An Si-time analysis based on a 24 h cycle starting at 2100 h yielded a better fit to the data than a "standard day " defined to start at midnight using the MDTN method. Exploratory regressions between the four MDTN parameters and several readily available independent variables did not yield consistent or significant predictive relationships. Cumulative distributions for either the KDE or MDTN methods are suggested for stochastic modeling purposes on a monthly basis, as they represent well observed histograms of SI times. The KDE method is suggested for use because of its simplicity in ungauged areas as long as neighboring data are available.

Sorption of ammonium (NH super(-) sub(4)) and NH sub(3) by mineral and organic solids decreases the proportion of free, aqueous ammoniacal N, which reduces volatilization potential. In the U.S., the High Plains region of Texas is subject to arid conditions with widely fluctuating temperatures. Furthermore, feedyard manure contains little soil and has high dry matter (DM) content; therefore, it is unclear if sorption parameters determined for soils or liquid manure systems are valid for feedyards. Our objectives were to use batch equilibration experiments to characterize NH super(-) sub(4) sorption by two feedyard manures. Kinetic and isotherm studies with (NH sub(4))2SO sub(4)/0.01M CaCl sub(2) solutions revealed that feedyard manures could sorb up to 227 cmol kg super(-1) NH super(+) sub(4)-N and that sorption was rapid and linearly related to NH super(+) sub(4) concentration. The Freundlich partitioning coefficient (K sub(p)) for NH super(+) sub(4) sorption averaged 13.3 L kg super(-1). From 58% to 96% of the sorbed NH super(-) sub(4) was readily desorbable with 0.01 M CaCl sub(2), and up to 81% was volatilized as NH sub(3) when manures were air-dried. Temperature influenced sorption, with 112%> more NH super(+) sub(4) sorption at 4 degree C than at 22 degree C. These results indicate that NH super(-) sub(4) sorption by manure on feedyard surfaces may temporarily reduce NH sub(3) volatilization, particularly during winter.

It has been developed over the past 25 years to allow for easy application to a large number of land management scenarios. Most general or field agency users of WEPP rely upon existing or special databases and/or interfaces that have been developed, tested, and verified by others. This article describes WEPP model calibration and validation procedures, under ideal situations (where all necessary input data and runoff/sediment observations are available) as well as under more typical and less ideal conditions. Two case study applications of the model from the literature are highlighted and discussed in detail as examples of single storm hillslope profile and continuous simulation watershed applications. Current and future development efforts on WEPP are also described.

The primary purpose of the model was to aid the USDA Natural Resources Conservation Service (NRCS) specialists in assessing nonpoint-source pollution from agricultural areas and to compare impacts of alternative management practices. Existing readily modifiable and new components were assembled into a field-scale model. Modelers also were charged with publication of model documentation, validation, and a user manual. Model validation with available data and sensitivity analyses of parameters in the hydrology, erosion, plant nutrient, and pesticide components were essential to demonstrate the model capabilities and effectiveness. Technology transfer to NRCS personnel was necessary to gain acceptance and proper use as well as to identify weaknesses and areas for needed improvement. Following publication and NRCS acceptance, improvements to CREAMS were made to better represent soil layering, crop rotations, irrigation, soil water routing, and chemical movement, which resulted in the Groundwater Loading Effects of Agricultural Management Systems (GLEAMS) model. Climatic records were increased from a maximum of 20 years to 50 years. The modifications were validated with available data and included in subsequent publications. The user manual gives more comprehensive description of the model parameters and their relative sensitivity. This article describes the historical development of the CREAMS and GLEAMS models with an emphasis on providing model users with an understanding of the degree of model verification and validation that was undertaken during development of these multidisciplinary models. Model calibration is discussed, including sensitive parameters and recommended procedures. Finally, two specific case studies are presented along with brief synopses of numerous case studies that have been used to validate model components. Future users are encouraged to use the model source code to further expand its utility for analyzing the nonpoint-source pollution impacts of agricultural management practices.

Ten pedons were sampled with the objective to assess the influence of soil pedogenesis on the vertical distribution of Fe, Mn, and trace elements through these sediments and into the underlying native alluvial materials. Depth of metal-enriched sediments varied from 20 to 104 cm. The pH was similar in both parent materials, ranging from 4.9 to 6.8. The metal-enriched sediments had a high concentration of Fe, Mn, and trace elements relative to horizons of native alluvium. Depth distribution of Fe, Mn, and ratios of Fe from selective dissolution as well as microscopic and macroscopic morphological expressions of redoximorphic features were evidence of pedogenic redistribution of elements. Results suggest that redistribution was largely driven by redox changes from seasonal flooding and high water tables, resulting in dissolution/precipitation of Fe-Mn hydrous oxides. Location of the highest concentration of elements varied with depth within the metal-enriched zone and was not apparently linked to a hydrologic discontinuity between parent materials. Initial deposition of hydrous oxides may be in the capillary fringe above the water table, but data suggests that once a zone of secondary Fe deposition was established, this cementation likely influenced soil hydrology. Subsequent deposition of hydrous oxides apparently continued at this pedogenic interface. Iron was present in various forms (crystalline and noncrystalline hydrous oxides, metal-organic complexes with humic substances) and these compounds function as sinks for trace elements.

This investigation was designed to directly assess the magnitude of competition among autonomous subunits of tillers within individual tussocks (i.e., integrated physiological units) to further define the mechanisms of tiller organization within this successful growth form. Experimentally constructed tussocks of Schizachyrium scoparium (Michx. Nash) were grown in the field in central Texas, USA, for 2 years with 1, 4, 8, or 12 autonomous subunits to span the range observed in naturally occurring local populations. Increasing numbers of subunits per tussock did not affect tiller density or the mean mass of individual vegetative or reproductive tillers, but it did intensify intratussock competition as evidenced by a large reduction in total tiller mass and number per subunit. This pattern of tiller organization is indicative of a division of labor within the tussock that is manifested as a tradeoff between competition among autonomous subunits and cooperation among tillers within these physiologically integrated subunits. We conclude that an increasing number of autonomous subunits associated with tussock basal expansion contributes to coarse-scale resource preemption and competitive ability, while resource sharing among tillers within subunits supports new tiller establishment and growth within this highly competitive microenvironment.Original Abstract: Les herbes en touffes se caracterisent par un arrangement spatial compact de talles contribuant a une forte competition dans la touffe. Cette recherche a ete concue pour evaluer directement l'amplitude de la competition parmi des sous unites autonomes de talles a l'interieur d'une touffe individuelle (c.-a-d., unite physiologique integree) afin de mieux definir les mecanismes d'organisation des talles sous cette forme efficace de croissance. Les auteurs ont construit des touffes du Schizachyrium scoparium (Michx. Nash) au champ, dans le centre du Texas aux Etats-Unis, au cours de deux annees et comprenant 1, 4, 8, ou 12 sous unites autonomes et ainsi couvrir l'amplitude des situations survenant dans les populations naturelles locales. L'augmentation du nombre de sous unites par touffe n'affecte pas la densite des talles ou la masse moyenne des talles vegetatifs ou reproductifs individuels, mais intensifie la competition dans la touffe comme le montre la forte reduction de la masse totale des touffes et du nombre par sous unite. Ce patron d'organisation des talles traduit une division du travail a l'interieur de la touffe se manifestant par une contre partie entre la competition entre les sous unites autonomes et la cooperation entre les talles dans ces unites physiologiques integrees. Les auteurs concluent qu'une augmentation du nombre de sous unites autonomes, associee avec l'expansion basale de la touffe, contribue a la capacite de preemption et de competitivite a grande echelle, alors que le partage des ressources entre les talles dans les sous unites supporte l'etablissement des talles et la croissance dans ce microenvironnement fortement competitif.

It was found that levels up to 0.3% resulted in yogurts with quality characteristics similar to the control yogurt. Higher levels of beta -glucan however retarded the fermentation process with noticeable difference in the characteristics of the yogurt. Examination of the morphologies of yogurt with and without beta -glucan revealed that beta -glucan formed aggregates with casein micelle and did not form phase-separated domains. This research demonstrated that beta -glucan could be added to yogurt up to 0.3%, which meets the nutrient guidelines, to have added nutritional benefits. Practical Application: Yogurt is known for its beneficial effects on human health and nutrition. Yogurt production and consumption is increasing in the United States every year. However, it is lacking in beta -glucans, which are recognized for their nutritional importance as functional bioactive ingredients. The main objective was to develop and characterize low-fat yogurts with added beta -glucan. This research demonstrated that beta -glucan could be added to yogurt up to 0.3%, which meets the nutrient guidelines for added nutritional benefits, without affecting the characteristics of yogurt significantly. This study will benefit the dairy industry by generating new products offering healthy alternatives.

Currently, household units with build-in inverter power supply units are available. These new generation MW ovens provide continuous, adjustable output and cooking, in contrast to the traditional rectifier-based ovens that rely on the on-off mechanism for control. This study attempted to apply a feedback power control (termed as modified or "smart" MW oven) and phosphate treatment to further improve heating uniformity and enhance food quality and safety. Listeria monocytogenes (Lm, 4-strain cocktail), Escherichia coli O157:H7 (Ec, 5-strain cocktail), and Salmonella spp. (Sal, 6-strain cocktail), surface inoculated onto catfish fillets (75 100 15 mm; weight 110 g), were heated using the modified MW oven to study the inactivation of the pathogens. The sensitivity of these 3 bacteria to MW heating was in the order of Ec (most), Lm, and Sal (least). Greater than 4 to 5 log CFU reductions of Ec, Lm, or Sal counts on catfish fillet surfaces were inactivated within 2 min of 1250 W MW heating, where the fillet surface temperature increased from 10 to 20 degree C to 80 to 90 degree C. MW heating caused degradation of catfish fillet texture, which was noticeable as early as 10 to 15 s after the heating started, as evidenced by bumping sounds. Bumping can be significantly reduced by soaking fillets in phosphate solution. However, the results may need verification if applied in different MW ovens and/or with foods positioned away the geometric oven center. This study successfully demonstrated the feasibility of applying MW energy to eliminate foodborne pathogens on fish fillets. Practical Application: The results demonstrated in this report with the "smart" microwave oven design may enhance microwaveable food safety and quality, and therefore promote the microwaveable food business.

In this study, MDR commensal Escherichia coli isolates from poultry were examined. Thirty-two E. coli isolates from broiler carcass rinses were selected based on their resistance to aminoglycosides, beta -lactams, chloramphenicols, tetracyclines, and sulfonamide antimicrobials. Microarray analysis for the presence of antimicrobial resistance and plasmid genes identified aminoglycoside [aac(6), aac(3), aadA, aph, strA, and strB], beta -lactam (bla sub(AmpC), bla sub(TEM), bla sub(CMY), and bla sub(PSE-1)) chloramphenicol (cat, flo, and cmlA) sulfamethoxazole (sulI and sulII), tetracycline [tet(A), tet(C), tet(D), and tetR], and trimethoprim (dfrA) resistance genes. IncA/C plasmid core genes were detected in 27 isolates, while IncHI1 plasmid genes were detected in one isolate, indicating the likely presence of these plasmids. PCR assays for 18 plasmid replicon types often associated with MDR in Enterobacteriaceae also detected one or more replicon types in all 32 isolates. Class I integrons were investigated by PCR amplification of the integrase I gene, intI1, and the cassette region flanked by conserved sequences. Twenty-five isolates were positive for the intI1 gene, and class I integrons ranging in size from similar to 1,000 to 3,300 bp were identified in 19 of them. The presence of class I integrons, IncA/C plasmid genes, and MDR-associated plasmid replicons in the isolates indicates the importance of these genetic elements in the accumulation and potential spread of antimicrobial resistance genes in the microbial community associated with poultry.

Determining the sufficiency of prey resources is an important consideration for initiating wolverine recovery, yet there are limited data on resource availability and needs. Our goal is to estimate prey requirements based on wolverine caloric needs and the caloric content of prey likely to be available. We achieve this goal by modifying existing models to account for wolverine biology. Models show a male wolverine requires 5096 kJ/day (2925-7462 kJ) and a female wolverine requires 3645 kj/day (2158-5439 kJ). This translates to an annual energy budget for males of 1.9 million kJ/yr that could be met by consuming the equivalent of approximately 8 mule deer/yr (Odocoileus hemionus) and 1.4 million kJ/yr for females that could be met by consuming the equivalent of less than 6 mule deer/yr. In light of published records of prey availability, these results suggest populations of wolverines could be sustained where recovery programs are being considered in Colorado and California. We suggest incorporating energetic needs of focal species, such as those calculated here for wolverines, into the assessment of resource availability before implementing recovery programs. Further, these estimates can be applied to management and conservation of wolverines throughout their range.

Spathius galinae Belokobylskij and Strazenac, a new idiobiont ectoparasitoid from the Russian Far East, currently is being considered for introduction to the United States for biological control of the emerald ash borer, Agrilus planipennis Fairmaire, whereas Tetrastichus planipennisi Yang, a koinobiont endoparasitoid native to China, is another natural enemy that already has been introduced in the same program. In a laboratory study, we examined the potential interactions between these two parasitoids when they compete for the same emerald ash borer host larvae. In multiple-choice assays where healthy emerald ash borer larvae were presented along with emerald ash borer larvae previously parasitized by T. planipennisi at different times, S. galinae attacked host larvae already parasitized by T. planipennisi for up to 4 d, but not 8 d. However, parasitism rates were significantly lower in previously parasitized hosts as compared with healthy host larvae. In no-choice tests where S. galinae females were presented either with healthy emerald ash borer larvae or emerald ash borer larvae parasitized by T. planipennisi at several earlier time points, S. galinae again parasitized significantly more healthy host larvae than T. planipennisi-parasitized larvae. These results suggest that the ectoparasitoid S. galinae can discriminate between healthy host larvae and T. planipennisi-parasitized larvae, and competitive interactions between the two parasitoids are likely to be minimal if coreleased by the emerald ash borer biological control program.

The annual runoff ratio (discharge divided by precipitation) increased about 0.1 per 300 m of mean catchment elevation over the range 1,800-2,400 m. Higher-elevation catchments have lower vegetation density, shallow soils with rapid permeability, and a shorter growing season when compared with those at lower elevations. Average annual temperatures ranged from 6.8 degree C at 2,400 m to 8.6 at 1,950 m elevation, with annual precipitation being 75-95% snow at the highest elevations vs. 20-50% at the lowest. Peak discharge lagged peak snow accumulation on the order of 60 days at the higher elevations and 20 to 30 days at the lower elevations. Snowmelt dominated the daily streamflow cycle over a period of about 30 days in higher elevation catchments, followed by a 15-day transition to evapotranspiration dominating the daily streamflow cycle. Discharge from lower elevation catchments was rainfall dominated in spring, with the transition to evapotranspiration dominance being less distinct. Climate warming that results in a longer growing season and a shift from snow to rain would result in earlier runoff and a lower runoff ratio.

The 2011 potato growing season saw the first report of zebra chip disease in Washington, Oregon, and Idaho; however, B. cockerelli has been recorded in this region every season at least for the past 7 yr. Studies were conducted to determine the relationship between psyllids collected from the Pacific Northwest potatoes in 2011 and those from the Southwestern and Central United States. High resolution melting analysis of the B. cockerelli mitochondrial Cytochrome C Oxidase subunit I-like gene was conducted on over 450 psyllids collected from numerous locations across the Central and Western United States. Results suggest that at least three potato psyllid haplotypes exist in the United States, correlating to the Central, Western, and Northwestern United States geographical regions. The high resolution melting analysis results were subsequently supported by DNA sequencing data.

We conducted laboratory bioassays to better understand the signals responsible for the formation and maintenance of southern chinch bug aggregations. In small arena assays, chinch bugs demonstrated a stronger aggregation response over time and aggregated more often on or beneath St. Augustinegrass leaf blades than on or under artificial leaf-like shelters constructed from white or green paper. In Y-tube olfactometer assays, bugs of different age and sex were attracted to volatiles from mixed-sex chinch bug aggregations and showed particular attraction to groups of adult female chinch bugs. Adult males and nymphs were also attracted to adult males. Nymphs were attracted to nymphs and were also more attracted to aggregation volatiles when they could see bugs in the arm of the Y-tube. Adult males were more attracted to short-winged than long-winged adults, while females and nymphs demonstrated no preference. All bugs were attracted to St. Augustinegrass volatiles when presented alone, but only males preferred the odor of grass over odor released from a chinch bug mixed-sex aggregation. When presented with a choice of grass and grass + aggregation volatiles, males preferred the combined treatment. The results of these assays suggest that a complex combination of life stage, sex, as well as plant and insect-derived signals influence chinch bug aggregation behavior.

Because some species causing stem injury in the United States have not been identified, potential biomass reductions to M. giganteus were measured using southwestern corn borer, Diatraea grandiosella Dyar (Crambidae), an insect pest of several related crops within the Andropogoneae. Results indicate D. grandiosella is capable of survival on whorl and stem tissue from hatch to 21 d in the laboratory, and field infestations with third instars support adult development, as exuviae were found during dissection of injured tillers. Relative to uninfested controls, M. giganteus tillers with stem injury yielded 12-30% less dry mass in four infestations over 2009-2010. As in some D. grandiosella hosts, data indicate decreased susceptibility to stem-boring as tillers increase in size or age. Regressions of residuals (observed - predicted mass) for injured M. giganteus tillers onto the cumulative length of tunnels per tiller also showed significant negative slopes (i.e., decreasing tiller mass with increasing tunnel length). Although D. grandiosella survival appeared low in both laboratory and field trials, results indicate that M. giganteus productivity could become limited by other stem-boring caterpillars known to attack Andropogoneae, including the following: Elasmopalpus lignosellus (Zeller) (Pyralidae), Diatraea saccharalis (F.) (Pyralidae), and Eoreuma loftini (Dyar) (Crambidae). For perennial grasses grown exclusively for biomass, certain management strategies for stem borers or other pests may be uneconomical or impractical, suggesting long-term investment in breeding for host plant resistance may be needed.

These findings suggest a need for improved knowledge of L. hesperus temperature-dependent reproductive development. We used nonlinear biophysical development rate models to describe the reproductive development of adult L. hesperus held under constant temperatures from 12.8 to 35.0 degree C. In addition, abdominal coloration was measured as a nondestructive indicator of reproductive maturity. The nonlinear models indicated most stages of ovary, seminal vesicle, and medial accessory gland development were subject to mild high-temperature inhibition, except for the stage of filled seminal vesicles. Development of filled seminal vesicles was subject to minor low-temperature inhibition and severe high-temperature inhibition. Estimated development times reflected extensive interindividual variation, especially at low temperatures. This variation suggests the opportunity to select for more rapid or more consistent reproductive development under the conditions of laboratory culture. Although presence of a dark aqua coloration of the ventral abdominal cuticle was statistically associated with reproductive maturity, especially in female L. hesperus, color-based predictions of reproductive maturity were often inaccurate for bugs reared at temperatures above or below 26.7 degree C. Therefore, use of abdominal coloration as an indicator of reproductive development in ecological studies seems inappropriate. The results provide mathematical descriptions of L. hesperus temperature-dependent reproductive development which should facilitate improved planning and interpretation of studies involving manipulation of adult reproductive status.

In particular, information on worker flight distances to crops blooming several months after nests have been established is invaluable. Here, we examined foraging patterns of Bombus vosnesenskii Radoszkowski in late-season blooming clover in the agriculturaldominated Willamette Valley in Oregon. Workers from 10 fields collected over 2 yr were assigned to full sibling families (colonies) by using eight microsatellite loci. With estimation of numbers of unseen species, we inferred the presence of 189 colonies from 433 bees genotyped in year 1, and 144 from 296 genotyped the next year. Worker foraging distance was estimated to be at least 11.6 km, half the distance between the most remote fields visited by the same colonies. Numbers of nests contributing workers to each field ranged from 15 to 163. Overall, 165 (50%) colonies foraged in two or more fields, and thus used common resources within the landscape. Estimates of average nest densities in the landscape each year ranged from 0.76/km2 to 22.16/km2, and highlighted the influences of various study parameters incorporated into the calculation including sample size, distances between sites, and analytical tools used to estimate unsampled individuals. Based on the results, bumble bees can fly long distances, and this could facilitate their survival in fragmented agricultural landscapes. This has important implications for the scale of habitat management in bumble bee conservation programs.

This invasive ant has been causing significant economic and ecological damage in infested areas. Because of the morphological and behavioral similarities to Nylanderia pubens Forel (Caribbean crazy ant) found in Florida, this ant was named Nylanderia sp. nr. pubens (Rasberry crazy ant). So far, morphometric and phylogenetic analyses have not determined if the two ants are the same or separate species. To determine the relationships between the two populations, a molecular approach was undertaken. Five novel genes with various functions from N. pubens and N. sp. nr. pubens were cloned, sequenced, and identified, including a chemosensory protein (NpCsp), the cyclophilinlike protein (NpClp), the fatty acid binding protein (NpFabp), the ferritin 2-like protein (NpFlp), and an odorant binding protein (NpObp). The cDNA sequences of NpCsp, NpFabp, NpFlp, and NpObp, shared 100% identity between N. sp. nr. pubens and N. pubens. The cDNA of NpClp shared 99% identity, with the only difference at the nucleotide position 358. Comparisons of four partial genomic DNA sequences from Caribbean and Rasberry crazy ants indicated 100% identity for a 710-bp partial genomic DNA sequence of cytochrome oxidase subunit I gene, 99% identity for a 774 bp, and a 452-bp partial genomic DNA sequence of NpFabp and NpObp containing noncoding regions, and 100% identity for a 289 bp partial genomic DNA sequence of NpCsp containing only coding region. This study showed that N. sp. nr. pubens in Texas is the same, or at most an intraspecific variant or ecotype of the species in Florida.

It attacks a wide range of hosts and is difficult to control using conventional insecticides. As part of our studies on the biology and control of X. germanus, we are trying to optimize conditions for rearing beetle progeny to adulthood in the laboratory. In this study we tested the brood production by X. germanus reared on artificial diet based on sawdust from American beech (Fagus americana L.), black walnut (Juglans nigra. L.), European buckthorn (Rhamnus cathartica L.), and red oak (Quercus rubra L.). We also tested the growth of different strains of the beetle fungal symbiont, Ambrosiella hartigii Batra, on these sawdust diets. Among the sawdust types tested, we found significantly higher average number of progeny produced on diet made with sawdust from European buckthorn (43.9 plus or minus 1.6) compared with those made with American beech (29.2 plus or minus 1.7), black walnut (25.5 plus or minus 1.9), or red oak (26.3 plus or minus 1.8). The percentage of females producing brood and the brood sex ratio (females:males) were not affected by sawdust type. Sex ratio, however, was correlated with progeny size, with fewer males produced as the number of progeny increased. In smaller broods the ratio observed was approximately 4:1; in larger broods it approached 20:1. Growth of the fungal symbiont varied with strain and with sawdust. Comparison of progeny production on sawdust-based diet with symbiont growth in vitro suggests that variables other than speed of symbiont growth may be more critical in optimizing brood production.

Small) is an aggressive invasive tree species that can be abundant in parts of its non-native range. This tree species has the capability of producing monocultures, by outcompeting native trees, which can be in or near wetlands that are utilized by breeding amphibians. Existing research suggests that leaf litter from invasive Chinese tallow reduces survival in larval anurans. The purpose of this study was to determine the effects of Chinese tallow leaf litter on anuran eggs. We exposed eggs of the Southern Leopard Frog (Lithobates sphenocephalus (Cope, 1886)) at various stages of development to different concentrations of Chinese tallow leaf litter to determine survival. Eggs in the earliest stages of development that we exposed to tallow leaf litter died, regardless of concentration; however, some more-developed eggs exposed to tallow leaf litter did hatch. We determined that the greater the concentration of tallow leaf litter, the lower the dissolved oxygen and pH levels we observed. We suggest that changes in these water-quality parameters are the cause of the observed mortality of anuran eggs in our experiments. Eggs exposed to water containing tallow leaf litter with dissolved oxygen <1.59 mg/L and a pH <5.29 did not survive to hatching.Original Abstract: Le suif vegetal de Chine (Triadica sebifera (L.) Small) est une essence d'arbre envahissante agressive qui peut localement etre abondante hors de son aire de repartition naturelle. Cette essence est capable de produire des monocultures en delogeant des essences indigenes pouvant se trouver dans des zones humides ou a proximite et que des amphibiens utilisent pour la reproduction. Les travaux existants suggerent qu'une couverture de feuilles mortes de suif vegetal de Chine reduit la survie de larves d'anoures. Le but de l'etude consiste a determiner les effets des feuilles mortes de suif vegetal sur les oeufs d'anoures. Nous avons expose des oeufs de grenouille leopard du Sud (Lithobates sphenocephalus (Cope, 1886)) a differents stades de leur developpement a differentes concentrations de feuilles de suif vegetal dans la couverture de feuilles mortes afin de determiner leur taux de survie. Les oeufs exposes aux stades les plus precoces de leur developpement a des feuilles mortes de suif vegetal sont morts, peu importe la concentration de ces dernieres, alors que certains oeufs a des stades plus avances ont eclos. Nous avons determine que plus la concentration de feuilles mortes de suif vegetal dans la couverture etait grande, plus les teneurs d'oxygene dissous et le pH etaient faibles.

Ecosystem structure and function can be permanently changed when keystone tree species such as the American chestnut (Castanea dentata) are eliminated from a whole range by disease. The fungal ascomycete pathogen Cryphonectria parasitica is responsible for causing chestnut blight. Once the pathogen was introduced into the Eastern US, where chestnuts were predominant, chestnuts were all but eliminated. This pathogen is currently causing extensive damage in Europe. A study in this issue of Molecular Ecology sheds new light on the pattern and process of emergence of this devastating plant pathogen (Dutech 2012). The authors used microsatellite markers to investigate the evolutionary history of C. parasitica populations introduced into North America and Europe. To infer sources of migrants and the migration events, the authors included putative source populations endemic to China and Japan, inferred potentially unsampled populations and conducted a multivariate population genetic and complex ABC analysis. Cryphonectria parasitica emerges as an example of an introduced pathogen with limited genotypic diversity and some admixture in the invaded ranges, yet repeated invasions into different areas of Europe and the United States. This work sheds new light on the emergence of C. parasitica providing compelling evidence that this pathogen emerged by repeated migration and occasional admixture.

Steers received a premix that added 0 (control; n=10) or 0.2mg/kg of chromium (n=10) to the total diet on a dry matter basis for 56 d. Steers were fitted with jugular catheters and rectal temperature (RT) recording devices on d 52. Blood samples were collected and sickness behavior scores assigned to each steer relative to an LPS challenge (0.5 mu g/kg) on d 55. Pre-LPS RT were greater in chromium-supplemented than in control steers. Post-LPS RT increased in both treatments, with control steers producing a greater change in RT than chromium-supplemented steers. Sickness behavior scores were greater in control than in chromium-supplemented steers post-LPS (P=0.03). Cortisol concentrations did not differ between treatments pre-LPS. Post-LPS cortisol concentrations increased but did not differ due to treatment. Concentrations of IL-4 increased post-LPS but were not affected by treatment pre- or post-LPS. Treatment did not affect pre-LPS TNF- alpha or IFN- gamma . Post-LPS TNF- alpha and IFN- gamma increased in both treatments, with chromium-supplemented steers producing greater TNF- alpha (P=0.005) and IFN- gamma (P=0.004) than control steers. Pre-LPS IL-6 was greater (P=0.027) in chromium-supplemented steers than in control steers. Post-LPS IL-6 increased in both treatments and was greater (P<0.001) in chromium-supplemented than in control steers. These data suggest that chromium supplementation enhances the acute phase response of steers to an LPS challenge, which may expedite recovery.

Effective and reliable techniques to evaluate soybean for resistance to this fungus are needed to work toward a management scheme that would utilize host resistance. Three experiments were conducted to investigate the use of a cut-stem inoculation technique to evaluate soybean genotypes for resistance to M. phaseolina. The first experiment compared aggressiveness of M. phaseolina isolates collected from soybean on different soybean genotypes. Significant (P 0.05). Soybean genotypes DT97-4290, DT98-7553, DT98-17554, and DT99-16864 had significantly (P < 0.05) lower RAUDPC than 7 of the 14 genotypes. The third experiment evaluated resistance in selected Phaseolus spp. and soybean genotypes. The range of RAUDPC for Phaseolus spp. was similar to that of soybean. The Phaseolus lunatus 'Bush Baby Lima' had significantly (P < 0.05) lower RAUDPC than P. vulgaris genotypes evaluated. The cut-stem inoculation technique, which has several advantages over field tests, successfully distinguished differences in aggressiveness among M. phaseolina isolates and relative differences among soybean genotypes for resistance to M. phaseolina comparable with results of field tests.

Single uredinial isolates (537 total) were derived from the collections and tested for virulence phenotype on 19 lines of 'Thatcher' wheat and a winter wheat line that are near-isogenic for 20 leaf rust resistance genes. In 2010, 38 virulence phenotypes were described in the United States. Virulence phenotypes MLDSD, TDBJG, and TCRKG were the three most common phenotypes. Phenotype MLDSD is virulent to Lr17 and Lr39/Lr41 and was widely distributed throughout the United States. Phenotype TDBJG is virulent to Lr24 and was found in both the soft red winter wheat and hard red winter wheat regions. Phenotype TCRKG is virulent to Lr11, Lr18, and Lr26 and was found mostly in the soft red winter wheat region in the eastern United States. Virulence to Lr21 was found for the first time in North America in isolates collected from spring wheat cultivars in North Dakota and Minnesota.

Plants engineered for glyphosate tolerance with a glyphosate-insensitive EPSPS take up and translocate the herbicide throughout the plant. In greenhouse experiments, we found that application of glyphosate at the recommended field application rate completely controlled alfalfa rust (Uromyces striatus) on 4-week-old plants inoculated with the fungus 3 days after glyphosate treatment. Control was effective in all seven cultivars tested. The level of protection declined with time after application, indicating that control is transitory and protection declined with time after inoculation, suggesting that protective treatments have fungistatic activity. Complete control of rust was obtained when glyphosate was applied up to 10 days after inoculation with rust spores, indicating that the herbicide also has curative activity. Treatment increased protection from anthracnose, caused by Colletotrichum trifolii, a hemibiotrophic pathogen, and reduced symptom severity for spring black stem and leaf spot, caused by Phoma medicaginis, a necrotrophic pathogen. These results indicate that glyphosate could be used to help manage foliar diseases in glyphosate-tolerant alfalfa.

In part, this is due to the extensive surveys in historically underexplored ecosystems (e.g., forest and stream ecosystems) undertaken to determine the spread of invasive species and the involvement of Phytophthora species in forest decline worldwide (e.g., oak decline). Brasier (41) cited the number of described species in 1999 at approximately 55, and there has been an increase of an additional 50 species or distinct taxonomic entities described between 2000 and 2007. This represents a near doubling in eight years! Ersek and Ribeiro (80) recently updated the list of described species to 100; since then, additional species have been named (some provisional), raising the total to 117 (Table 1) with a number of other distinct taxonomic entities in the process of formal description. The number of species will likely continue to increase as more surveys are completed and greater attention is devoted to clarifying phylogenetic relationships and delineating boundaries in species complexes. The development of molecular resources, including the recent comprehensive multigene phylogenetic analysis of the genus (32), the availability of credible sequence databases to simplify identification of new species (www.phytophthoradb.org, www.phytophthora-id.org, www.qbank.eu, and www.boldsystems.org), and the sequencing of several genomes (107, 278) have provided a solid framework to move forward. Gaining a better understanding of the biology, diversity, and taxonomic relationships within the genus will be important for the improvement of identification and diagnostic protocols. This information is much needed considering the impact invasive or exotic Phytophthora species have had on natural ecosystems and the regulatory issues associated with their management. Reviews by Cooke et al. (61) and O'Brien et al. (217) are noteworthy for providing additional information on molecular identification and detection.

The insecticide seed treatment Poncho Beta has proven to be effective in controlling curly top in sugar beet but was only evaluated under light to moderate disease pressure. Thus, the insecticide seed treatments Poncho Beta, NipsIt INSIDE, and Cruiser Force were evaluated under severe curly top pressure (six viruliferous beet leafhoppers per plant) in field studies during the 2010 and 2011 growing seasons on two commercial sugar beet cultivars. In addition, the foliar insecticides Movento, Provado, and Scorpion were also evaluated. The seed treatments and Scorpion reduced curly top symptoms by 33 to 41% (P < 0.0001) and increased root yield by 55 to 95% (P < 0.0001), sucrose content by 6.5 to 7.2% (P = 0.0013 to <0.0001), and estimated recoverable sucrose by 58 to 96% (P < 0.0001) when compared with the untreated check.

Even under severe disease pressure 50 to 55 days after planting, neonicotinoid seed treatments can effectively reduce curly top, increase yield, and help protect against early-season insect pest pressure.

The purpose of our study was to determine whether temperature might be a significant limiting factor in the development of soybean rust in the southeastern United States. Soybean plants infected with Phakopsora pachyrhizi were incubated in temperature-controlled growth chambers simulating day and night diurnal temperature patterns representative of the southeastern United States during the growing season. At 3-day intervals beginning 12 days after inoculation, urediniospores were collected from each plant and counted. The highest numbers of urediniospores were produced when day temperatures peaked at 21 or 25 degree C and night temperatures dipped to 8 or 12 degree C. When day temperatures peaked at 29, 33, or 37 degree C for a minimum of 1 h/day, urediniospore production was reduced to 36, 19, and 0%, respectively, compared with urediniospore production at the optimum diurnal temperature conditions. Essentially, no lesions developed when the daily temperature high was 37 degree C or above. Temperature data obtained from the National Climatic Data Center showed that temperature highs during July and August in several southeastern states were too high for significant urediniospore production on 55 to 77% of days. The inhibition of temperature highs on soybean rust development in southeastern states not only limits disease locally but also has implications pertaining to spread of soybean rust into and development of disease in the major soybean-producing regions of the Midwestern and northern states. We concluded from our results that temperature highs common to southeastern states are a factor in the delay or absence of soybean rust in much of the United States.

We measured volumetric soil water across 25-cm profiles ([thetas] sub(25cm)) and springtime whole-plant water- and carbon-fluxes of the exotic Lehmann lovegrass (Eragrostis lehmanniana) and a native bunchgrass, bush muhly (Muhlenbergia porteri), following typical (55 mm in 2009) and El Nino-enhanced accumulations (154 mm in 2010) in a SE Arizona savanna. Across both years, [thetas] sub(25cm) was higher under lovegrass plots, with similar evapotranspiration (ET) between lovegrass and bush muhly plots. However, in 2010 transpiration (T) was higher in bush muhly than lovegrass, implying higher soil evaporation in lovegrass plots maintained similar ET. Net ecosystem carbon dioxide exchange (NEE) was similar between lovegrass and bush muhly plots in 2009, but was more negative in bush muhly plots following El Nino, indicating greater CO sub(2) assimilation. Ecosystem respiration (R sub(eco)) and gross ecosystem photosynthesis (GEP) were similar between lovegrass and bush muhly plots in 2009, but were higher in bush muhly plots in 2010. As a result, lovegrass plots reduced ecosystem water-use efficiency (WUE sub(e) = NEE/ET), while bush muhly WUE sub(e) remained constant between 2009 and 2010. Concurrent whole-plant WUE (WUE sub(p) = GEP/T ) did not change in lovegrass plots, but increased in bush muhly plots between these years. We concluded that cool-season precipitation use is not a component of Lehmann lovegrass invasive success, but that the change in ET partitioning and attendant shifts in cool-season WUE sub(e) may increase interannual variation in ecosystem water- and carbon-exchange dynamics in the water-limited systems it dominates.

BLD, caused by the fungus Apioplagiostoma populi (syn. Plagiostoma populi) described by Cash and Waterman (1), takes its name from the characteristic dark purple to brown pigmentation of infected leaves. A. populi has not been cultured on artificial media either from diseased tissues or cast ascospores. An anamorph has not been conclusively identified but spores from blister-like acervuli on symptomatic leaves have been suggested to function as spermatia (3). In an attempt to describe the imperfect stage of A. populi. collections of diseased leaves of P. alba x sieboldii and P. alba x grandidentala 'Crandon' growing in a plantation near Rose-mount, MN, were made on September 14, 2011 (leaves attached to shoots, rolled inward), October 12, 2011 (leaves attached or on the ground, tightly rolled inward), and November 1, 2011 (most leaves on the ground), and examined in the laboratory for fungal development. Leaf laminae from the September 14 collection were uniformly covered with erumpent, subcuticular blister-like acervuli on the adaxial surface only, containing unicellular, colorless spores ranging in size from 2.2 to 10.0 x 2.0 to 5.0 mu m (mean 3.6 x 6.2 mu m) (n = 100). Attempts to germinate and obtain cultures from these spores on common artificial media were unsuccessful. On leaves collected October 12, the blister-like acervuli were predominantly empty or releasing spores and immature perithecia of A. populi were present. Leaves collected on November 1 contained immature perithecia but were heavily colonized by surface saprophytic fungi and no intact blister-like acervuli were present. DNA was extracted from bulked samples of spores removed from the blister-like acervuli in leaves from multiple trees collected on September 14 using the DNeasy Plant Mini Kit (Qiagen Sciences, Germantown, MD). The internal transcribed spacer (ITS2) region of rDNA was PCR amplified and sequenced with primers ITS3 and ITS4. BLASTn searches revealed that sequences from three independent bulked samples were homologous (99% identity, 353 of 355 nucleotides) to A. populi from isolated perithecia (GenBank Accession No. GU205341) (2). The inability of the spores to germinate, the timing of their development and release, and the tight, inward roll of infected leaves facilitating their spread across the upper leaf surface suggest that these spores function as spermatia in the life cycle of A. populi and the blister-like acervuli in which they develop are spermogonia.

AN - 1030874095; 22849693 AB - To determine the toxicokinetics of N-(methylsuccinimido)anthranoyllycoctonine-type low larkspur alkaloids in beef cattle. 5 Black Angus steers and 35 Swiss Webster mice. -Low larkspur (Delphinium andersonii) was collected, dried, ground, and administered to 5 steers via oral gavage to provide a dose of 12 mg of N-(methylsuccinimido)-anthranoyllycoctonine alkaloids/kg. Steers were housed in metabolism crates for 96 hours following larkspur administration; heart rate was monitored continuously, and blood samples were collected periodically for analysis of serum concentrations of 16-deacetylgeyerline, methyllycaconitine, geyerline, and nudicauline and assessment of kinetic parameters. The LD(50) of a total alkaloid extract from D andersonii was determined in Swiss Webster mice. -The alkaloids were quickly absorbed, with a maximum serum concentration achieved within 18 hours after administration. Geyerline and nudicauline coeluted as 1 peak and were considered together for toxicokinetic analysis. Mean ± SD elimination half-life was 18.4 ± 4.4 hours, 15.6 ± 1.5 hours, and 16.5 ± 5.1 hours for 16-deacetylgeyerline, methyllycaconitine, and geyerline and nudicauline, respectively. There were significant differences in maximum serum concentration, amount absorbed, and distribution half-life among the 4 alkaloids. The mouse LD(50) was 9.8 mg/kg. -Results suggested that clinical poisoning was likely to be most severe approximately 18 hours after exposure. Cattle should be closely monitored for at least 36 hours after initial exposure. Additionally, a withdrawal time of approximately 7 days would be required to clear > 99% of the toxic alkaloids from the serum of cattle that have ingested low larkspur.

A new automated BOX-PCR and Pulsed-Field Gel Electrophoresis (PFGE) were used to subtype enterococcal isolates from broiler and layer litter and surface and groundwater. All surface water samples (n=12) were positive for enterococci, as were 11% (3/28) of groundwater samples. Enterococcus faecium (n=90) was isolated from all sources, while Enterococcus faecalis (n=59) was isolated from all sources except layer litter. The majority of E. faecalis originated from broiler litter (28/59; 47.5%) while the majority of E. faecium were isolated from layer litter (29/90; 32.2%). E. faecalis grouped primarily by source using BOX-PCR. Isolates from water samples were dispersed more frequently among PFGE groups containing isolates from poultry litter. E. faecium strains were genetically diverse as overall clustering was independent of source by both molecular methods. Subgroups of E. faecium isolates based upon source (layer litter) were present in BOX-PCR groups. Three individual E. faecalis groups and two individual E. faecium groups were 100% similar using BOX-PCR; only one instance of 100% similarity among isolates using PFGE was observed. Although enterococci from litter and water sources were grouped together using BOX-PCR and PFGE, isolates originating from water could not be definitively identified as originating from poultry litter. Automation of BOX-PCR amplicon separation and visualization increased the reproducibility and standardization of subtyping using this procedure.

These VvGAI1 sequence variants included some mimics of the known GAI-like mutant alleles discovered in grape, wheat, barley, corn, Brassica, and Arabidopsis. In general, plant height and related traits such as length of internodes and inflorescences were significantly reduced for most of the mutant alleles studied, regardless of which promoter was used. Interestingly, the numbers of rosette leaves and lateral branches were generally reduced when a 35S promoter was used to express the mutant alleles, but increased when an Arabidopsis or grape GAI promoter was used. Furthermore, the 35S plants often displayed curly and small leaves. In contrast, the leaves of the plants carrying mutant alleles controlled by a GAI promoter were of variable size, dark green and rarely curly. In addition, when certain VvGAI1 mutant alleles were under the control of the grape GAI1 promoter, the number of pods on inflorescences was significantly increased, but some of the pods produced few seeds due to partial sterility. On the basis of the systematic evaluation of various VvGAI1 mutant alleles in Arabidopsis, we concluded that the VvGAI1 mutant alleles mimicking the GAI or GAI-like mutant variants discovered in wheat, barley and Brassica could potentially be useful for the improvement of grapevine plant architecture.

All atrazine + S-metolachlor exposures resulted in significantly reduced radicle development (p < 0.001). A stimulatory effect for coleoptile development was noted in the three highest atrazine (only) exposures (p = 0.0030, 0.0181, and 0.0016, respectively). This research provides data concerning the relative sensitivity of T. latifolia seeds to pesticides commonly encountered in agricultural settings, as well as critical understanding and development of using T. latifolia in phytoremediation efforts for pesticide exposures.

In addition to its growing global importance for feed, fuel, and starch, cassava has long been vital to food security in Sub-Saharan Africa. Climate change is expected to have its most severe impact on crops in food insecure regions, yet little is known about how cassava productivity will respond to climate change. The most important driver of climate change is globally increasing atmospheric CO2 concentration ([CO2]). However, the potential for cassava to enhance food security in an elevated [CO2] world is uncertain as greenhouse and open top chamber (OTC) study reports are ambiguous. Studies have yielded misleading results in the past regarding the effect of elevated [CO2] on crop productivity, particularly in cases where pots restricted sink growth. To resolve these conflicting results, we compare the response of cassava to growth at ambient (ca. 385 ppm) and elevated [CO2] (585 ppm) under field conditions and fully open air [CO2] elevation. After three and half months of growth at elevated [CO2], above ground biomass was 30% greater and cassava root tuber dry mass increased over 100% (fresh weight increased 89%). High photosynthetic rates and photosynthetic stimulation by elevated [CO2], larger canopies, and a large sink capacity all contributed to cassava's growth and yield stimulation. Cassava exhibited photosynthetic acclimation via decreased Rubisco capacity early in the season prior to root tuber initiation when sink capacity was smaller. Importantly, and in contrast to a greenhouse study, we found no evidence of increased leaf N or total cyanide concentration in elevated [CO2]. All of our results are consistent with theoretical expectations; however, the magnitude of the yield increase reported here surpasses all other C3 crops and thus exceeds expectations.

This is problematic because physical activity has been shown to attenuate weight gain in children. Active commuting to school is one way of increasing children's physical activity. However, given the high rates of child pedestrian injury, preventive strategies to reduce these risks are needed. Programs such as the Walking School Bus provide opportunities to not only promote pedestrian safety but increase children's energy expenditure.

A total of 20 sampling points of the crop row in 2009 and 15 sampling points in 2010, each 1.5m long, was sampled along two 101-m transects running perpendicular to the woodland edge in each crop field. A random distribution of stink bugs (focusing on Euschistus servus, Nezara viridula, and Chinavia hilaris) was found most often with respect to the woodland edge of all crops examined. The exception occurred mainly in corn fields, where more stink bugs were found at the crop edge when flowering alternative hosts were present in the woodland edges. In 113 fields of four major crops grown in this area (7 of the 120 fields were excluded from analysis due to lack of stink bugs or limited woodland edges), the woodland edge was not a major source from which stink bugs colonized these crops. These results suggest that edge-specific control measures should not be concentrated at those field edges adjacent to woodlands.

Although there is a lack of long-term measurements of CWD across the diverse forest ecosystems of the US, there is an abundance of line intersect sampling (LIS) transects used for monitoring efforts such as fuel loadings. In order to provide an objective method for monitoring the carbon/biomass dynamics of individual CWD pieces for use with LIS, this study developed and tested a CWD piece matching algorithm for inventory plots where LIS was used to sample CWD at two points in time across the eastern US. Results indicated that a CWD piece matching algorithm may be constructed using three steps: (1) matching the location of each piece, (2) matching individual piece metrics (e.g., large-end diameter), and (3) scoring an index of many CWD attributes with adjustment by decay and measurement error (i.e., quality control tolerances). For most forest types in the US, this study's algorithm matched between 20% and 40% of CWD pieces over time ( approximately 5years). The algorithm performed poorly in forests potentially disturbed by floods and/or with relatively high mean annual temperatures and subsequent fast decay rates. Due to this influence of decay, the algorithm attained low match rates for highly decayed or small-sized CWD pieces. The algorithm should not be used to estimate changes in carbon/biomass within a stock change accounting framework. However, the algorithm may provide a method to aggregate a subset of paired LIS CWD observations over time to inform CWD dynamics research at large-scales.

AN - 1027679521; 22713715 AB - The filamentous fungus Fusarium verticillioides can cause disease of maize and is capable of producing fumonisins, a family of toxic secondary metabolites linked to esophageal cancer and neural tube defects in humans and lung edema in swine and leukoencephalomalacia in equines. The expression of fumonisin biosynthetic genes is influenced by broad-domain transcription factors (global regulators) and Fum21, a pathway-specific transcription factor. LaeA is a global regulator that in Aspergillus nidulans, affects the expression of multiple secondary metabolite gene clusters by modifying heterochromatin structure. Here, we employed gene deletion analysis to assess the effect of loss of a F. verticillioides laeA orthologue, LAE1, on genome-wide gene expression and secondary metabolite production. Loss of Lae1 resulted in reduced expression of gene clusters responsible for synthesis of the secondary metabolites bikaverin, fumonisins, fusaric acid and fusarins as well as two clusters for which the corresponding secondary metabolite is unknown. Analysis of secondary metabolites revealed that, in contrast to a previously described Fusarium fujikuroi lae1 mutant, bikaverin production is reduced. Fumonisin production is unchanged in the F. verticillioides lae1 mutant. Complementation of the F. verticillioides mutant resulted in increased fumonisin production. Copyright © 2012 Elsevier Inc.

In the laboratory, adults of Carabus nemoralis Muller, Nebria brevicollis (F.), Pterostichus algidus LeConte, Pterostichus melanarius (Illiger), and Scaphinotus marginatus Fischer (Coleoptera: Carabidae) consumed black vine weevil, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae) eggs, larvae and/or pupae placed on the surface. The same five carabid species showed no impact or low removal rates of O. sulcatus larvae that had burrowed into the root of potted strawberry plants. In an assay with only P. melanarius, adults consumed O. sulcatus larvae placed on the soil surface more frequently than larvae buried 1.3 or 5 cm below. In a field study, the density of adult carabids, predominantly P. melanarius, was manipulated with augmented, exclusion, and open control plots (2 2 m). Manipulating carabid density had no impact on the removal of sentinel O. sulcatus larvae and pupae that were buried belowground which is consistent with laboratory observations. Increasing carabid density within augmented plots led to greater removal of red clover seeds, Trifolium pratense L., placed on the soil surface in the first year. Decreasing carabid density within exclusion plots resulted in fewer marketable fruits compared to control plots in both years. These results suggest that certain adult carabids may have limited impact belowground, and some beneficial impacts above-ground with pest control and crop protection.

However, long-term hydrologic data are needed to better evaluate the potential benefits of conservation tillage. To that end, hydrologic monitoring was conducted for 11 years on a 1.2ha hillslope located in the Atlantic Coastal Plain region of south central Georgia, USA. The site was equally divided between two tillage treatments, conventional-tillage (CT) and strip-tillage (ST), with cotton and peanut produced in rotation. Each tillage block was divided into three 0.2ha plots to evaluate runoff as a function of tillage and slope position. Soil texture and hydraulic characteristic data were quantified to evaluate potential impacts on hydrologic processes including runoff, infiltration, and lateral subsurface flow. Surface runoff from CT averaged 22% of annual precipitation while that from ST averaged 13%. When paired by tillage and landscape position, annual runoff from ST was significantly less than annual runoff from CT (p=0.025). Monthly surface runoff from CT was consistently greater than that from ST, particularly during May through August. Increased infiltration as a consequence of the reduced tillage led to significantly greater average annual subsurface losses from ST (19%) than from CT (10%) (p=0.025). Results indicated that slope position and textural differences may also have influenced site hydrology. Plots at the top of the landscape where finer soil textures were observed produced greater runoff than plots at lower landscape positions where coarser textures were observed. In summary, the ST cotton/peanut rotation can be expected to significantly reduce runoff but increase lateral subsurface flow. As a consequence, water budgets from the two tillage systems were essentially equal. Similar decreases in surface runoff and increases in lateral subsurface flow can be expected to occur in landscapes in the Atlantic Coastal Plain Region where strip tillage is adopted.

Similar morphological characteristics, cellular fatty acid profiles, and 16S rRNA gene sequences show that the isolates are members of the same species. These characteristics also show that the isolates belong to the genus Pseudomonas with P. graminis, P. putida, and P. stutzeri as close relatives. The 16S rRNA gene of the H2 super(T) strain differed from that of type strains for P. graminis, P. putida, and P. stutzeri by 1.9, 2.5, and 2.7 %, respectively, indicating that the H2 super(T), H6, and H7 strains are related to P. graminis, P. putida, and P. stutzeri but are different enough to represent a novel species. The G+C content of the three strains averaged 61.2 plus or minus 0.8 mol% which is similar to the values reported for P. graminis (61), P. putida (61.6), and P. stutzeri (62.2-65.5). The major cellular fatty acids present in the H2 super(T) strain were C sub(18:1) omega 7c/C sub(18:1) omega 6c (34.3 %), C sub(16:1) omega 6c/C sub(16:1) omega 7c (27.4 %), C sub(16:0) (20.6 %), C sub(12:0) (7.9 %), C sub(12:0) 3-OH (4.5 %), and C sub(10:0) 3-OH (3.1 %). The name Pseudomonas kuykendallii sp. nov. is proposed for these bacteria.

Detailed measurements of sand transport rate, bed texture, and bed topography were collected for four different discharges at approximately the same flow depth of 0.2 m for 11 different elevations of sand in the gravel bed. Sand transport was measured using both physical samples and a density cell. For a given flow rate, increases in the elevation of sand relative to gravel resulted in decreases of bed shear stress from 32-44% and increases in sand transport by 3 orders of magnitude. For the highest two discharges, the sand merged into a small number of long and low bed forms that translated through and over the gravel bed. A collapse of the transport data was accomplished by relating the sand transport rate to the bed shear stress scaled by the cumulative probability distribution function of the gravel surface evaluated at the height of the mean sand bed.

16791251 AB - Mechanical fuel reduction treatments have been implemented on millions of hectares of western North American forests. The redistribution of standing forest biomass to the soil surface by mulching treatments has no ecological analog, and this practice may alter soil processes and forest productivity. We evaluated the effects of mulch addition on soil nitrogen availability at 15 fuel reduction projects in the southern Rocky Mountains and Colorado Plateau regions of Colorado. Mulching treatments removed 38Mgha-1of standing forest biomass on average and added 2-4cm of irregular woody fragments to the O horizon. Mulching lowered maximum summer soil temperatures and increased soil moisture. The N added in mulch was equivalent to half the amount contained in untreated O horizons, and mulch had a lower N concentration and wider C:N ratio than material of similar size in untreated areas. Plant-available soil N, measured in situ with ion exchange resins was reduced under heavily-mulched experimental plots the year mulching occurred, but the effect did not persist for a second year. The nitrogen content of freshly-applied mulch increased by 9, 24 and 55kgNha-1year-1 in plots receiving 22, 49 and 105Mgha-1 of mulch material on average. In contrast, 5-year-old mulch released N regardless of amount of mulch added. Three to five years after treatment, available N was 32% higher in mulched fuel reduction treatments compared to untreated forests. Heavy mulch application has the potential to temporarily reduce soil N availability in limited areas, but as implemented in Colorado conifer forests, fuel reduction mulch treatments increase soil N availability.

Our surveys examined forest composition of oak woodlands; the degree of injury and proportion of oaks infested with either A. auroguttatus (ICA and AZ) or A. coxalis (MX); and the progression of aerially mapped oak mortality in San Diego Co. (ICA). By most measures of impact that we evaluated, the effect on oaks by the two Agrilus spp. was relatively low in their native regions, but significantly higher by A. auroguttatus at ICA sites. Larger diameter red oak species have been the preferred hosts of A. auroguttatus in AZ and ICA sites, and red oaks greater than approx. 13cm in DBH throughout California are likely at risk of injury from this invasive pest. At sites in AZ there was no evidence of infestation by A. auroguttatus on living or dead white oak species, whereas at ICA sites we recorded a minor amount of infestation by A. auroguttatus on living individuals of a white oak species (Quercus engelmannii Greene), but no mortality. In contrast, a white oak from MX sites (Quercus peduncularis) was more frequently infested by A. coxalis than were indigenous red oaks. Across all ICA sites, A. auroguttatus has infested 61% of the live larger diameter oaks and killed 13% of the oak component of the forest (vs. 4% infested and 2% dead in AZ, respectively). At survey plots near the predicted origin of the outbreak in CA, over 90% of the larger diameter red oaks have been infested. Nearly 90% of the dead oaks surveyed across all ICA sites showed evidence of previous injury symptoms from A. auroguttatus. Aerial oak mortality polygons associated with A. auroguttatus have expanded similar to 50km in nine years, but our analysis confirms that the outbreak appears to still be confined to San Diego Co. The distance of oak mortality polygons from the predicted origin of the outbreak explained the most variance in a principal component analysis. The invasive population of A. auroguttatus is a significant conservation and ecological threat to the oak woodlands of California and should be managed accordingly, especially by restricting firewood movement.

Recent reports suggest that both bacteria have been associated independently and concomitantly with disease on commercial farms. Monovalent vaccines have been developed for disease control; however, the most effective delivery strategy has been via intraperitoneal (IP) injection. Due to handling stress and the cost associated with injecting each fish, a better strategy is to combine the monovalent vaccines into bivalent formulations. The objective of the present study was to test the ability of a killed bivalent S. iniaeand V. vulnificusvaccine delivered by IP injection at protecting sex reversed hybrid tilapia (Oreochromis niloticusOreochromis aureus) against challenge with each bacterium, independently. In two independent trials, vaccination of tilapia with the bivalent vaccine conferred protective immunity against V. vulnificus and S. iniae as demonstrated by significant differences (P<0.05) in survival curves between the sham-vaccinated and vaccinated groups. Relative percent survival values ranged from 79 to 89% for V. vulnificus and 69 to 100% for S. iniae following challenge of bivalent vaccinated fish. Use of this bivalent formulation may be a cost-effective strategy to reduce losses in tilapia co-infected with these two important bacterial pathogens.

E. Smith) or fall armyworm is an important agricultural pest of a number of crops in the western hemisphere. In the United States, infestations in corn acreages extend from the Mexican to the Canadian border. Because fall armyworm does not survive prolonged freezing, the infestations annually affecting most of North America are migrants from southern Texas and Florida, where winter temperatures are mild and host plants are available. A haplotype method was developed that can distinguish between these two geographically distant overwintering populations, with the potential to delineate the associated migratory pathways. Several years of collections from major corn-producing areas in the southern, central, and eastern United States were used to map the geographical distribution of the fall armyworm haplotypes. From these haplotype profiles, it was possible to develop the most detailed description yet of the annual northward movements of fall armyworm. The consistency of these results with past studies and the implications on our understanding of fall armyworm biology are discussed. A better understanding of fall armyworm populations and their movement is critical for the development of strategies to predict infestation levels and eventually control this pest in the United States. We developed a genetic method that can be used to compare the movements of the overwintering populations from Texas and Florida of the fall armyworm subpopulation (designated the corn-strain) that primarily infests corn and cotton. We used this method to analyze fall armyworm collections from major corn-producing regions in the southern, central, and eastern U.S. The data was used to extrapolate the migratory patterns of the Texas and Florida overwintering populations and identify areas of overlap and where genetic interactions could occur.

In this study, concentrated flow simulations on disturbed and undisturbed rangelands were used to estimate the erodibility and to evaluate the performance of linear and power law equations that describe the relationship between erosion rate and several hydraulic parameters. None of the hydraulic parameters consistently predicted the detachment capacity well for all sites, however, stream power performed better than most of other hydraulic parameters. Using power law functions did not improve the detachment relation with respect to that of the linear function. Concentrated flow erodibility increased significantly when a site was exposed to a disturbance such as fire or tree encroachment into sagebrush steppe. This study showed that burning increases erosion by amplifying the erosive power of overland flow through removing obstacles and by changing the soil properties affecting erodibility itself. However, the magnitude of fire impact varied among sites due to inherent differences in site characteristics and variability in burn severity. In most cases we observed concentrated flow erodibility had a high value at overland flow initiation and then started to decline with time due to reduction of sediment availability. Thus we developed an empirical function to predict erodibility variation within a runoff event as a function of cumulative unit discharge. Empirical equations were also developed to predict erodibility variation with time postdisturbance as a function of readily available vegetation cover and surface soil texture data. Key Points * Concentrated flow erodibility in rangelands decreases within a runoff event * Fire changes the soil properties affecting erodibility * Stream power provided the best linear function to describe the detachment rate JF - Water Resources Research AU - Al-Hamdan, Osama Z AU - Pierson, Frederick B AU - Nearing, Mark A AU - Williams, CJason AU - Stone, Jeffry J AU - Kormos, Patrick R AU - Boll, Jan AU - Weltz, Mark A AD - USDA, Agricultural Research Service, Northwest Watershed Research Center,Boise, Idaho,USA., osama.al-hamdan@ars.usda.gov Y1 - 2012/07// PY - 2012 DA - Jul 2012 SP - [np] PB - American Geophysical Union, 2000 Florida Ave., N.W.

Contemporary users of an outdoor recreation area are often inadequately represented in these planning decisions, due to the high cost and time required for user surveys that have traditionally been used to represent these stakeholders. A case example of the application of an alternative research method termed rapid appraisal (RA) is described. Data collected using rapid appraisal was used to help resolve disagreements on future planning and development options for the Little Molas Recreation Area (LMRA). The entire RA process was completed in one month's time, with results which provided a reliable stakeholder supplement to working group recommendations to the Forest Service for their proposed LMRA redevelopment plan.

However, the mechanism of this phenomenon is not fully understood. Here we describe the effect of Si on growth, and uptake and subcellular distribution of Cd in maize plants in relation to the development of root tissues. Methods Young maize plants (Zea mays) were cultivated for 10 d hydroponically with 5 or 50 mu m Cd and/or 5 mm Si. Growth parameters and the concentrations of Cd and Si were determined in root and shoot by atomic absorption spectrometry or inductively coupled plasma mass spectroscopy. The development of apoplasmic barriers (Casparian bands and suberin lamellae) and vascular tissues in roots were analysed, and the influence of Si on apoplasmic and symplasmic distribution of super(109)Cd applied at 34 nm was investigated between root and shoot. Key Results Si stimulated the growth of young maize plants exposed to Cd and influenced the development of Casparian bands and suberin lamellae as well as vascular tissues in root. Si did not affect the distribution of apoplasmic and symplasmic Cd in maize roots, but considerably decreased symplasmic and increased apoplasmic concentration of Cd in maize shoots. Conclusions Differences in Cd uptake of roots and shoots are probably related to the development of apoplasmic barriers and maturation of vascular tissues in roots. Alleviation of Cd toxicity by Si might be attributed to enhanced binding of Cd to the apoplasmic fraction in maize shoots.

Part of this progress has been the emergence of two biogeographic patterns involving invasive plants and soil microbes. First, in their non-native ranges invasive plants commonly interact differently with the same soil microbes than native plants. Second, in their native ranges, plants that are invasive elsewhere commonly interact functionally with soil microbes differently in their home ranges than they do in their non-native ranges. These studies pose a challenge to a long-held paradigm about microbial biogeography - the idea that microbes are not limited by dispersal and are thus free from the basic taxonomic, biogeographical and evolutionary framework that characterizes all other life on Earth. As an analogy, the global distribution of animals that function as carnivores does not negate the fascinating evolutionary biogeographic patterns of carnivores. Other challenges to this notion come from new measurements of genetic differences among microbes across geographic boundaries, which also suggest that meaningful biogeographic patterns exist for microorganisms. Scope and Conclusions We expand this discussion of whether or not 'everything is everywhere' by using the inherently biogeographic context of plant invasions by reviewing the literature on interactions among invasive plants and the microorganisms in the rhizosphere. We find that these interactions can be delineated at multiple scales: from individual plants to continents. Thus the microbes that regulate major aspects of plant biology do not appear to be exempt from the fundamental evolutionary processes of geographical isolation and natural selection. At the important scales of taxonomy, ecotype and ecosystem functions, the fundamental ecology of invaders and soil microbes indicates that everything might not be everywhere.

Cross-sectional, observational study. What We Eat in America (WWEIA), the dietary intake component of the US National Health and Nutrition Examination Survey (NHANES). Individuals aged greater than or equal to 1 year in 2003-2004 (n 8249) and 2005-2006 (n 8437) with one complete 24 h recall. The estimate for the percentage of individuals who reported total drinking water in 2005-2006 was significantly (P < 0.0000) smaller (76.9 %) than that for 2003-2004 (87.1 %), attributable to a lower percentage reporting tap water (54.1 % in 2005-2006 v. 67.0 % in 2003-2004; P = 0.0001). Estimates of mean tap water intake differed between the survey cycles for men aged greater than or equal to 71 years.

S. noctilio is an invasive woodwasp, is considered a major economic pest of pine, and has a severe effect on North American pine species planted in the Southern hemisphere. The mortality factors of siricid larvae were determined in three host species (Pinus sylvestris, Pinus resinosa, and Pinus strobus) from naturally infested trees in the northeastern USA. Siricid larvae were classified at the time of sampling as: (1) healthy, (2) parasitized by rhyssines (Hymenoptera: Ichneumonidae), (3) parasitized by Ibalia spp. (Hymenoptera: Ibaliidae), (4) parasitized by nematodes (Tylenchida: Neotylenchidae), and (5) dead from unknown causes. Combining data from the three host species, the average percentage of larvae that were healthy was 66%, 10% of the larvae were parasitized by rhyssines, 18% were parasitized by Ibalia spp., 1% were infected with unidentified nematodes, and about 5% of the larvae were dead in the galleries. Information from this study has important implications for understanding population regulation mechanisms in an invasive species, and will be critical for developing integrated pest management plans for S. noctilio.

Subsequently, land managers need effective restoration tools to reseed native vegetation back into these degraded systems. In order to develop successful post-fire restoration approaches in these communities, it is critical that we understand the mechanisms that impair reseeding success. Our objective was to quantify the influence of soil water repellency on seedling emergence and plant growth in a greenhouse study using soil cores obtained from beneath burned Juniperus osteosperma trees. Soil cores were seeded with either Elymus wawawaiensis or Agropyron cristatum, and watered with either a high (watered daily) or a low water regime (watered every 5 days). During the first watering event, water repellency was ameliorated in half the cores by adding a wetting-agent comprised of alkylpolyglycoside-ethylene oxide/propylene oxide block copolymers. Results showed that water repellency reduced seedling emergence and seedling survival by decreasing soil moisture availability. Wetting-agents improved ecohydrologic properties required for plant growth by decreasing runoff and increasing the amount and duration of available water for seedling emergence, survival, and plant growth. These results indicate that soil water repellency can act as an ecological threshold by impairing establishment of reseeded species after a fire. Where restoration efforts are limited by soil water repellency, wetting agents have the potential to improve the success of post-fire reseeding efforts. Future work is needed to validate these findings in the field.

Inadequate control of the disease has often resulted in potato yield losses. We assessed the efficacy of fungicides, phosphoric acid and stinging nettle extract combinations for late blight control at two locations in Kenya. Disease severity, relative area under disease progress curves (RAUDPC), pathogen lesions and tuber yield were quantified during the 2008 and 2009 cropping cycles. The application of metalaxyl alternated with phosphate resulted in the greatest suppressive effects on late blight. The average late blight severity ranged from 3.5 to 34% in 2008 and 4.7 to 50% in 2009 at Tigoni location. RAUDPC for the same location ranged from 5 to 40% and 5 to 50% in 2008 and 2009, respectively. Similar levels of late blight severity were recorded at Marimba location in both years. Lesion growth and pathogen lesion numbers on potato plants differed significantly (p < 0.05) among treatments. Fungicides, phosphoric acid and stinging nettle extract varied in late blight control. Potato tuber yield varied among treatments. Phosphoric acid treatment had significantly (p < 0.05) greater tuber yield compared to metalaxyl at both locations. Field plots treated with plant extracts from stinging nettle resulted in the lowest tuber yield compared to other treatments with the exception of the untreated control. Fungicides, phosphoric acid, stinging nettle extract and their combinations can be readily effective in the suppression of late blight severity and pathogen lesions with moderate increases in tuber yield.

The fungi cause diseases in crops worldwide and some of the secondary metabolites, such as DON, can adversely affect animal health and food safety. To monitor DON in wheat rapidly, a biosensor using the principle of biolayer interferometry (BLI) was developed. The signal from the sensor was substantially amplified through the use of a primary antibody-colloidal gold conjugate. The amplification was much greater in the presence of wheat matrix than in buffered solution, suggesting matrix components may have contributed to the enhancement. The improved signal provided by the amplification allowed for the development of rapid qualitative and quantitative assays. The limit of detection of the method was 0.09 mg kg super(-1); the limit of quantitation was 0.35 mg kg super(-1). Recovery from wheat spiked over the range from 0.2 to 5 mg kg super(-1) averaged 103% (RSD = 12%). The quantitative assay compared favourably (r super(2 )= 0.9698) with a reference chromatographic method for 40 naturally contaminated wheats. The qualitative assay was able to classify accurately the same group of 40 samples as either above or below a 0.5 mg kg super(-1) threshold. These results suggest that the BLI technique can be used to measure DON in wheat rapidly.

Low levels of fumonisins were detected in nine of 43 wheat samples with kernel black point disease that were obtained from across the United States. A subset of samples was contaminated with F. proliferatum as well as with F. fujikuroi, F. nygamai, F. thapsinum and F. verticillioides, species closely related to F. proliferatum and morphologically similar to it in that they produce chains of asexual spores, or conidia. Nevertheless, of conidial chain-forming fusaria isolated from symptomatic wheat, F. proliferatum dominated. In greenhouse tests, isolates of F. proliferatum and the other species recovered from wheat samples were able to cause symptoms of kernel black point and, in some cases, low levels of fumonisin contamination of wheat. These data add to the understanding of the risk of fumonisin contamination of wheat and the potential for Fusarium species to cause kernel black point disease and fumonisin contamination of wheat. Further, the results of this study indicate that while US-grown wheat can sporadically be contaminated by fumonisins, the natural contamination levels seem to be low. The observations made provide evidence that fumonisins are not likely to be a factor contributing to the ability of Fusarium to cause kernel black point disease.

While the "buckle" of this Stroke Belt coincides with the Southeastern Coastal Plain region of North and South Carolina and Georgia, there is a paucity of information pinpointing specific causes for this phenomenon. A number of studies posit that an exposure event-potentially microbial in nature-early in life, could be a risk factor. The most likely vector for such an exposure event would be the soils of the Southeastern Coastal Plain region. These soils may have chemical and physical properties which are conducive to the growth and survival of microorganisms which may predispose individuals to stroke. To this aim, we correlated SC stroke mortality data to soil characteristics found in the NRCS SSURGO database. In statewide comparisons, depth to water table (50 to 100 cm, R = 0.62) and soil drainage class (poorly drained, R = 0.59; well drained, R = -0.54) both showed statistically significant relationships with stroke rate. In a 20 county comparison, depth to water table, drainage class, hydric rating (hydric soils, R = 0.56), and pH (very strongly acid, R = 0.66) all showed statistically significant relationships with stroke rate. These data should help direct future research and epidemiology efforts to pinpoint the exact exposure events which predispose individuals to an increased stroke rate.

Characterizing spatial variability of soil nutrients in relations to landscape location is important for understanding the effects of future land use change on soil nutrients and water pollution. We hypothesized that cattle congregation site may have higher concentrations of phosphorus and nitrogen than in the pasture and grazing site or the adjoining forest site. This study assessed levels of Mehlich-1 extractable P, total inorganic N, and soil P saturation in relation to landscape locations in subtropical beef cattle pasture. Soil samples were collected during the spring and fall of 2005 to 2007 from three 19 adjoining landscape sites that are associated with beef cattle operation. These sites consisted of three locations: congregation, grazing, and forest sites. The levels of extractable P, total inorganic N, and P saturation in soils varied with landscape location. Congregation site had the highest concentration of extractable P of 36.1 mg kg super(-1), followed by grazing site of 17.7 mg kg super(-1), and forest site of 8.2 mg kg super(-1). Spatial distribution of total inorganic nitrogen across the landscape was higher for congregation site (2.3 mg kg super(-1)) than forest site (0.9 mg kg super(-1)) and grazing site (0.7 mg kg super(-1)). The overall spatial distribution of extractable P from congregation site to forest site can be described by P=-4.2x+45.8; (R super(2)=0.97**); the best-fit models for total inorganic N was 0.04x super(2)-0.6x+3.5; (R super(2)=0.89**) and for soil P saturation was -3.6x+36.2; (R super(2)=0.92**). Results show that the levels of extractable P, total inorganic nitrogen, and soil phosphorus saturation were decreasing from the congregation site to forest site. Although our results may have had supported our hypothesis that congregation site typical on Florida ranchers have greater concentrations of extractable P than in grazing site and forest site, the average extractable P at all three landscape locations did not exceed the crop requirement threshold of 36 mg kg super(-1) and the water quality protection threshold of 150 mg kg super(-1). Our current pasture management including cattle rotation in terms of grazing days and current fertilizer application had thus no negative environmental impact on landscape with cow-calf operation.

We evaluated the performance and accuracy of automated passive capillary wick samplers (PCAPs) for their ability to monitor and estimate real-time drainage water fluxes by comparing amounts of drainage recorded by the datalogger from the tipping buckets with manually collected drainage amounts. Drainage water fluxes were online estimated and manually collected below the rootzone of a sugarbeet-potato-barley using five years of data. Twelve automated PCAPs with outside sampling surface dimensions of 91x31x87cm were placed 90cm below the soil surface in a Lihen sandy loam. Drainage water amounts recorded by the datalogger from the tipping bucket were compared with manually collected drainage water amounts using several statistical methods. The relative root mean square values (RRMSE) were 81%, 49%, 16%, 58%, 72%, and 62% and logging efficiency (EF) values were 0.889, 0.914, 0.975, 0.885, 0.901, and 0.907 for 2006, 2007, 2008, 2009, 2010 and 5-yr combined, respectively. Overall, statistical results indicated that our automated PCAP samplers performed well and were accurately able to continuously monitor and estimate drainage water fluxes below the rootzone of a cropping system in the vadose layer without the need for costly and time-consuming supportive sampling methods. Slight variations between the logged and collected drainage water amounts may have resulted from human sampling error, reproducibility and mechanical operational problems with the PCAP assembly.

The catastrophic landslide of 1977 together with surrounding landslides in the Lubietova area were analysed with the help of persistent scatterers (PS) technique in order to evaluate recent and past deformations of the unstable slopes. Although long-term precise geodetic monitoring of the 1977 landslide revealed differential deformations inside the sliding mass, due to the lack of the PS located inside the landside caused by temporal decorrelation, unfortunately, these records could not be directly compared. The adjacent landslides with sufficient number of PS were analysed by transformation of the line of sight displacements recorded by the sensors to the slope vector direction. This procedure allowed identification of the precise boundaries of the actively moving landslide parts and the updating of the landslide inventory for the Lubietova area.

This study investigated shallow groundwater (SGW) nutrient dynamics in septic areas at the northern part of the Lower St. Johns River Basin, Florida, USA. Thirty-five SGW-monitoring wells, located at nine different urban areas served by septic systems, were used to collect the SGW samples seasonally and/or biweekly for a duration of 3 years from 2003 to 2006. Analytical results showed that there were 16 wells with nitrate concentrations exceeding the US Environmental Protection Agency's drinking water limit (10 mg L super(-1)). There also were 11 and 14 wells with total Kjeldahl nitrogen (TKN) and total phosphorus (TP) concentrations, respectively, exceeding the ambient water quality criteria (0.9 mg L super(-1) for TKN and 0.04 mg L super(-1) for TP) recommended for rivers and streams in nutrient Ecoregion XII (Southeast USA). In general, site variations are much greater than seasonal variations in SGW nutrient concentrations. A negative correlation existed between nitrate/nitrite-nitrogen (NO sub(x)-N) and TKN as well as between NO sub(x)-N and ammonium ( NH 4 + ), whereas a positive correlation occurred between TKN and NH 4 + . Furthermore, a positive correlation was found between reduction and oxidation (redox) potential and water level, while no correlation was observed between potassium concentration and redox potential. This study demonstrates a need to investigate the potential adverse impacts of SGW nutrients from the septic areas upon the deeper groundwater quality due to the nutrient penetration and upon the surface water quality due to the nutrient discharge.

One method of decreasing amounts of nitrogen entering rivers or lakes is the transport of runoff through vegetated drainage ditches. Vegetated drainage ditches can enhance the mitigation of nutrients from runoff; however, the efficiency of nitrogen removal can vary between plant species. The efficiency of three aquatic macrophytes, cutgrass (Leersia oryzoides), cattail (Typha latifolia), and bur-reed (Sparganium americanum), to mitigate dissolved and total nitrogen from water was investigated. Replicate mesocosms of each plant species were exposed to flowing water enriched with ammonium and nitrate for 6 h, allowed to remain stagnant for 42 h, and then flushed with non-enriched water for an additional 6 h to simulate a second storm event. After termination of the final simulated runoff, all vegetated treatments lowered total nitrogen loads exiting mesocosms by greater than 50%, significantly more than unvegetated controls, which only decreased concentrations by 26.9% (p less than or equal to 0.0023). L. oryzoides and T. latifolia were more efficient at lowering dissolved nitrogen, decreasing ammonium by 42 plus or minus 9% and 59 plus or minus 4% and nitrate by 67 plus or minus 6% and 64 plus or minus 7%, respectively. All treatments decreased ammonium and nitrate concentrations within mesocosms by more than 86% after 1 week. However, T. latifolia and L. oryzoides absorbed nitrogen more rapidly, lowering concentrations by greater than 98% within 48 h. By determining the nitrogen mitigation efficiency of different vegetative species, plant communities in agricultural drainage ditches can be managed to significantly increase their remediation potential.

A theoretical model of technology adoption and insurance incentive effects for a high- and low-risk technology is developed and explored empirically using a unique dataset of skip-row agronomic trial data. A multivariate nonparametric resampling technique is developed, which augments the trial data with a larger dataset of conventional yields to improve estimation efficiency. Skip-row adoption is found to increase mean yields and reduce risk in areas prone to drought. RMA insurance rules have incentive-distorting impacts which disincentivize skip-row adoption.

Presently, we tested the antimicrobial activity of hydrolysable-rich blackberry, cranberry and chestnut tannin extracts and condensed tannin-rich mimosa, quebracho and sorghum tannins (each at 100 mg/mL) against C. jejuni via disc diffusion assay in the presence of supplemental casamino acids. We found that when compared to non-tannin-treated controls, all tested tannins inhibited the growth of C. jejuni and that inhibition by the condensed tannin-rich mimosa and quebracho extracts was mitigated in nutrient-limited medium supplemented with casamino acids. When tested in broth culture, both chestnut and mimosa extracts inhibited growth of C. jejuni and this inhibition was much greater in nutrient-limited than in full-strength medium. Consistent with observations from the disc diffusion assay, the inhibitory activity of the condensed tannin-rich mimosa extracts but not the hydrolysable tannin-rich chestnut extracts was mitigated by casamino acid supplementation to the nutrient-limited medium, likely because the added amino acids saturated the binding potential of the condensed tannins. These results demonstrate the antimicrobial activity of various hydrolysable and condensed tannin-rich extracts against C. jejuni and reveal that condensed tannins may be less efficient than hydrolysable tannins in controlling C. jejuni in gut environments containing high concentrations of amino acids and soluble proteins.

The incorporation of antimicrobials into edible films could serve as an additional barrier against pathogenic and spoilage microorganisms that contaminate food surfaces. The objective of this study was to investigate the antimicrobial effects of carvacrol and cinnamaldehyde, incorporated into apple, carrot, and hibiscus-based edible films against Listeria monocytogenes on contaminated ham and bologna. Ham or bologna samples were inoculated with L. monocytogenes and dried for 30 min, then surface wrapped with edible films containing the antimicrobials at various concentrations. The inoculated, film-wrapped samples were stored at 4 degree C. Samples were taken at day 0, 3, and 7 for enumeration of surviving L. monocytogenes by plating on appropriate media. Carvacrol films showed better antimicrobial activity than cinnamaldehyde films. Compared to control films without antimicrobials, films with 3% carvacrol induced 1 to 3, 2 to 3, and 2 to 3 log CFU/g reductions on ham and bologna at day 0, 3, and 7, respectively. Corresponding reductions with 1.5% carvacrol were 0.5 to 1, 1 to 1.5, and 1 to 2 logs, respectively. At day 7, films with 3% cinnamaldehyde reduced L. monocytogenes population by 0.5 to 1.5 and 0.5 to 1.0 logs on ham and bologna, respectively. Inactivation by apple films was greater than that by carrot or hibiscus films. Apple films containing 3% carvacrol reduced L. monocytogenes population on ham by 3 logs CFU/g on day 0 which was 1 to 2 logs greater than that by carrot and hibiscus films. Films were more effective on ham than on bologna. The food industry and consumers could use these films to control surface contamination by pathogenic microorganisms. Practical Application: Antimicrobial edible, food-compatible film wraps prepared from apples, carrots, and hibiscus calyces can be used by the food industry to inactivate Listeria monocytogenes on widely consumed ready to eat meat products such as bologna and ham. This study provides a scientific basis for large-scale application of edible fruit- and vegetable-based antimicrobial films on foods to improve microbial food safety.

We evaluated defoliation impacts on above- and belowground production, and net ecosystem exchange of CO2 (NEE), in a wet sedge (Carex nebrascensis Dewey)-dominated plant community. In June or July of 2004-2005, experimental plots were clipped to 10 cm stubble height and paired control plots left unclipped. All plots were clipped to 2.5 cm in mid-September, and end-of-season and season-long aboveground production calculated. Root ingrowth cores were used to estimate annual root production and root length density (RLD). A portable gas exchange system and plexiglass chamber were used to measure NEE in 2005. An elevated water table in 2005 vs. 2004 was associated with higher (P0.05). Clipping reduced (P less than or equal to 0.05) end-of-season aboveground standing crop by 33% to 73% depending on clipping month and year. Effects of clipping month on season-long aboveground production were inconsistent between years; June clipping decreased (P less than or equal to 0.05) production (-10%) in 2005 and July clipping decreased (P less than or equal to 0.05) production (-25%) in 2004. NEE for June-clipped plots recovered within 1 mo of clipping, whereas NEE for plots clipped in July remained below unclipped levels at the end of the growing season. Water table levels strongly influenced below-:aboveground ratios, although total production was relatively stable between years. Year effects overwhelmed clipping effects on season-long aboveground production. Defoliation after mid-summer did not allow recovery of photosynthetic capacity by the end of the growing season, suggesting the potential for long-term impact with regular late-season defoliation. Los ecosistemas riverenos proveen muchos servicios, incluyendo ser una fuente importante de forraje para operaciones de pastoreo. Evaluamos los impactos de la defoliacion en la produccion aerea y subterranea, y el intercambio neto de CO2 (NEE), en una comunidad de humedales dominada por juncos (Carex nebrascensis Dewey). En junio o julio de 2004-2005, las parcelas experimentales fueron cortadas 10 cm por encima del suelo y parcelas control en pares se dejaron sin cortar. Todas las parcelas fueron cortadas a 2.5 cm a mediados de septiembre, y al final de la temporada y la produccion aerea de toda la temporada la fue calculada. Los nucleos de crecimiento interno de la raiz se usaron para estimar la produccion anual de raiz y la densidad de la longitud radicular (RDL). Un sistema portable de intercambio de gases y una camara plexiglass se utilizaron para medir NEE en 2005. Un alto nivel de agua en 2005 vs. 2004 asociado con una alta (P0.05). El corte redujo (P less than or equal to 0.05) la produccion aerea al final de la temporada de 33% a 73% dependiendo del ano y el mes de corte. Los efectos de corte en cada mes sobre produccion aerea fueron inconsistentes entre anos, los cortes durante junio redujeron (P less than or equal to 0.05) la produccion (-10%) en 2005 y los cortes durante julio redujeron (P less than or equal to 0.05) la produccion (-25%) en 2004. NEE en las parcelas cortadas en Junio se recuperaron dentro del mes despues del corte. Ademas NEE para las parcelas cortadas en julio permanecieron por debajo de los niveles de las no-cortadas al final de la etapa de crecimiento. Los niveles de la tabla de agua influenciaron fuertemente la tasa subterranea:aerea, aunque la produccion total fue relativamente estable entre anos. Los efectos de los cortes anuales afectaron la produccion anual aerea durante toda la temporada. La defoliacion despues de la mitad del verano no permitio la recuperacion de la capacidad fotosintetica al final de la epoca de crecimiento, sugiriendo el potencial impacto a largo plazo con defoliaciones regulares al final de la temporada.

In these systems, however, seeded species often fail to establish. A recent study in Wyoming big sagebrush steppe suggested that over 90% of seeded native grass individuals die before seedlings emerged. This current study examines the timing and rate of seed germination, seedling emergence, and seedling death related to this demographic bottleneck. We seeded monocultures of two native perennial bunchgrasses, Pseudoroegenaria spicata (Pursh) A. Love and Elymus elymoides (Raf.) Swezey, and one introduced bunchgrass, Agropyron desertorum (Fisch. ex Link) Schult., in 2007, 2008, and 2009 and tracked sown seed and seedling fate. Across the study years and species we found that germination was rapid and high, with species obtaining 50% germination by December, less than 2 mo after planting. Emergence of germinated seed did not occur until late February for A. desertorum and March for the two native grasses. In 2007 the majority of emergence and death was constrained to several weeks, whereas in 2008 and 2009 emergence and death was distributed across several months. The timing of seedling emergence did not influence survival probability or midday plant water potential (probability of exceedance A. desertorum (0.51) in 2 of the 3 study yr (probability of exceedance >0.98). The early germination of grasses following fall seeding, and the long 2- to 3-mo period that germinated grass seed remain in the soil before emerging, support the hypothesis that seedling recruitment might be limited largely by ecological processes and conditions during winter or early spring (such as soil freeze-thaw events, seed pathogens, or physical crusts). Delaying seeding to early winter or spring and other management tools that mitigate these factors driving this bottleneck might greatly improve restoration outcomes in these systems. Las resiembras son una herramienta clave de manejo para pastizales aridos. En estos sistemas, sin embargo, las especies sembradas a menudo no se establecen. En un estudio reciente en un pastizal de Artemisia en Wyoming se sugiere que mas del 90% de los individuos sembrados de pastos nativos mueren antes que la plantula germine. Este estudio examina la epoca y tasa de germinacion de las semillas, la aparicion de la plantula, y la muerte de plantula relacionadas con el cuello de botella demografico. Se sembraron monocultivos de dos especies nativas de pastos amacollados, Pseudoroegenaria spicata (Pursh) A. Love y Elymus elymoides (Raf.) Swezey, y tambien un pasto amacollado introducido, Agropyron desertorum (Fisch. ex Link) Schult., durante 2007, 2008, y 2009 y se le dio seguimiento a las semillas sembradas asi como el destino de las plantulas. A traves de los anos de estudio y especies se vio que la germinacion fue rapida y alta, con la obtencion de la germinacion del 50% en diciembre, menos de 2 meses despues de la siembra de especies. La aparicion de semillas germinadas no ocurrio hasta finales de febrero para A. desertorum y en marzo para las dos especies de pastos nativos. En 2007 la mayoria de aparicion y muerte estaba limitada a varias semanas mientras que en 2008 y 2009 el surgimiento y la muerte se distribuyeron a traves de varios meses. El tiempo de aparicion de las plantulas no influyo en la probabilidad de la supervivencia o al potencial de agua de la planta al mediodia o (probabilidad de superacion A. desertorum (0.51) en dos de los tres anos de estudio (probabilidad de superacion >0.98). La germinacion temprana de gramineas despues de que cae la semilla y el periodo tardo de dos a tres meses la semilla germinada permanece en el suelo antes de emerger y apoya la hipotesis que el reclutamiento de plantulas puede estar altamente limitado por el proceso ecologico y las condiciones durante el invierno o el inicio de la primavera tales (como la descongelacion del suelo, los patogenos de la semilla, o las costras fisicas). Retrasando la siembra a principios del invierno o primavera y usando otras herramientas de manejo que mitiguen los factores que impulsan este cuello de botella se puede mejorar considerablemente los resultados de la restauracion en estos sistemas JF - Rangeland Ecology & Management AU - James, J J AU - Rinella, MJ AU - Svejcar, T AD - Plant Physiologist, USDA-ARS Eastern Oregon Agricultural Research Center, Burns, OR 97720, USA, jeremy.james@oregonstate.edu Y1 - 2012/07// PY - 2012 DA - Jul 2012 SP - 409 EP - 417 PB - Society for Range Management VL - 65 IS - 4 SN - 1550-7424, 1550-7424 KW - Ecology Abstracts KW - Germination KW - Seeds KW - Grasses KW - Artemisia KW - Water potential KW - Recruitment KW - Formicidae KW - Survival KW - Pathogens KW - Steppes KW - Demography KW - Soil KW - Rangelands KW - Indigenous species KW - Agropyron desertorum KW - Planting KW - Seed germination KW - Elymus elymoides KW - Seeding KW - Seedlings KW - Freeze-thawing KW - D 04060:Management and Conservation UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1034814904?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Aecology&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Rangeland+Ecology+%26+Management&rft.atitle=Grass+Seedling+Demography+and+Sagebrush+Steppe+Restoration&rft.au=James%2C+J+J%3BRinella%2C+MJ%3BSvejcar%2C+T&rft.aulast=James&rft.aufirst=J&rft.date=2012-07-01&rft.volume=65&rft.issue=4&rft.spage=409&rft.isbn=&rft.btitle=&rft.title=Rangeland+Ecology+%26+Management&rft.issn=15507424&rft_id=info:doi/10.2111%2FREM-D-11-00138.1 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2012-08-01 N1 - Number of references - 48 N1 - Last updated - 2013-06-28 N1 - SubjectsTermNotLitGenreText - Germination; Seeds; Grasses; Recruitment; Water potential; Survival; Pathogens; Steppes; Soil; Demography; Indigenous species; Rangelands; Planting; Seed germination; Seeding; Seedlings; Freeze-thawing; Agropyron desertorum; Artemisia; Formicidae; Elymus elymoides DO - http://dx.doi.org/10.2111/REM-D-11-00138.1 ER - TY - JOUR T1 - Using Very-Large-Scale Aerial Imagery for Rangeland Monitoring and Assessment: Some Statistical Considerations AN - 1034814888; 17047309 AB - The availability of very-large-scale aerial (VLSA) imagery (typically less than 1 cm ground-sampling-distance spatial resolution) and techniques for processing those data into ecosystem indicators has opened the door for routinely using VLSA imagery in rangeland monitoring and assessment. However, for VLSA imagery to provide defensible information for managers, it is crucial to understand the statistical implications of designing and implementing VLSA image studies, including consideration of image scale, sample design limitations, and the need for validation of estimates. A significant advantage of VLSA imaging is that the researcher can specify the scale (i.e., spatial resolution and extent) of the images. VLSA image programs should plan for scales that match monitoring questions, size of landscape elements to be measured, and spatial heterogeneity of the environment. Failure to plan for scale may result in images that are not optimal for answering management questions. Probability-based sampling guards against bias and ensures that inferences can be made to the desired study area. Often collected along flight transects, VLSA imagery lends itself well to certain probability-based sample designs, such as systematic sampling, not often used in field studies. With VLSA image programs, the sample unit can be an entire image or a portion of an image. It is critical to define the sampling unit and understand the relationship between measurements and estimates made from the imagery. Finally, it is important to statistically validate estimates produced from VLSA images at selected locations using quantitative data of the same scale and more precise and accurate than the VLSA image techniques. The extent to which VLSA imagery will be useful as a tool for understanding the status and trend of rangelands depends as much on the ability to build the imagery into robust programs as it does on the ability to quickly and relatively easily collect VLSA images over large landscapes. La disponibilidad de imagenes aereas a gran escala (IAGE) (normalmente menos de un cm de de distancia de resolucion espacial en el terreno) y tecnicas que procesen esos datos dentro de indicadores del ecosistema han abierto la puerta para que de manera rutinaria se use IAGE en pastizales en monitoreo y evaluacion. Sin embargo, para IAGE proveer informacion defendible para administradores es crucial para entender las implicaciones estadisticas para disenar e implementar estudios de IAGE que incluyan consideraciones de escala de la imagen, limitaciones en el diseno de muestreo y la necesidad de validacion de los estimadores. Una ventaja significativa de IAGE es que el investigador puede definir la escala (ejm. resolucion espacial y extension) de la imagen. Los programas de IAGE deberian planear escalas que empaten preguntas de monitoreo, el tamano de los elementos del paisaje a ser medidos y la heterogeneidad espacial del medioambiente. Fallas en planear la escala puede resultar en imagenes que no son optimas en resolver las preguntas del administrador. Muestreos basados en probabilidad protegen contra sesgo y aseguran que la inferencia puede ser hecha para la area de estudio deseada. Seguido, recoleccion a lo largo de vuelos en transectos, IAGE permite bien a cierto diseno de muestra basado en probabilidad como diseno sistematico no usado a menudo en estudios de campo. Con programas IAGE la unidad de muestreo puede ser la imagen completa o una porcion de esta. Es fundamental definir la unidad de muestreo y entender la relacion entre medidas y estimaciones hechas de la imagen. Finalmente, es importante validar estadisticamente los estimadores producidos de IAGE es lugares seleccionados usando datos cuantitativos de la misma escala y mas precisos y certeros que las tecnicas de IAGE. La amplitud a la cual IAGE sera de utilidad como herramienta para entender el estatus y tendencia de los pastizales, depende en gran medida en la habilidad para construir imagenes en programas robustos sino tambien con la habilidad de recolectar imagenes IAGE rapidamente y relativamente facil sobre grandes paisajes.

Limited information exists about effects of soil amendment-based erosion and runoff mitigation practices in low fertility acidic sites. The current study evaluates the use of 20 kg ha super(-1) polyacrylamide (PAM), 0.3 kg ha super(-1) ammonium laureth sulfate (ALS), 5,000 kg ha super(-1) fluidized bed combustion residue (FBC), and 5,000 kg ha super(-1) coal-fired power plant by-product gypsum (GYP) in reducing erosion and runoff from a disturbed, acidic, dystrophic Appalachian soil. Study plots of 1 m by 1 m, arranged in a randomized complete block design with three replications, were established on an abandoned grassland hillside in southern West Virginia. Plots were rototilled before annual surface applications of each of the above materials and that of FBC plus PAM, for four consecutive years, starting in 1996. In the fourth year, Wheeler rye grass was broadcast on the plots. Sediment, runoff, and soil and runoff chemical composition were monitored during a period of two to four months after application. No significant differences were found between ALS treatment and control (where no additive was applied). By the fourth year, the FBC-containing treatments had increased soil pH by an average of one pH unit, which resulted in improved plant nutritional status and biomass production. Mean runoff concentrations of calcium (Ca) for the four years averaged 236 mg L super(-1) compared to 6 mg L super(-1) in the control. FBC decreased zinc (Zn) concentrations in runoff by nearly four-fold compared to the control. Gypsum addition resulted in even greater increases in runoff concentration of Ca and sulfur (S), but effects on soil pH and plant biomass were not significantly different from the control. No differences in runoff volume among any of the treatments were observed during the first year, yet in general, FBC-containing treatments decreased runoff for the remainder of the experiment. In the fourth year, after seeding with Wheeler rye grass, the FBC-containing treatments reduced runoff by up to 51% and sediment by 37% compared to the control. FBC + PAM was found to be the most effective treatment in enhancing plant growth and reducing sediment and runoff on the tested soil.

Adaptive management can be generally defined as an iterative decision-making process that incorporates formulation of management objectives, actions designed to address these objectives, monitoring of results, and repeated adaptation of management until desired results are achieved (Brown and MacLeod 1996; Savory and Butterfield 1999). However, adaptive management is often criticized because very few projects ever complete more than one cycle, resulting in little adaptation and little knowledge gain (Lee 1999; Walters 2007). One significant criticism is that adaptive management is often used as a justification for undertaking actions with uncertain outcomes or as a surrogate for the development of specific, measurable indicators and monitoring programs (Lee 1999; Ruhl 2007).

We contend that significant policy and educational barriers stand in the way of expanding the use of this conservation tool. Well-managed pasture systems combine vigorous perennial vegetation cover, reduced pesticide and fertilizer inputs, and lower costs of production using ecological approaches to generate ecosystem services for society, as well as economic sustainability for the producer. The majority of currently available conservation policy tools were designed to address either rangeland grazing situations in the western United States or conservation cropping in the eastern United States. To promote well-managed pastures in the eastern United States, resource managers and government agencies struggle to adapt programs that are really designed for annual row crop systems. Additional educational and technical assistance resources are needed for promoting well-managed pasture-based farming in the region. This paper summarizes the potential of well-managed pasture systems to provide ecosystem services, provides thoughts for discussion on the barriers to adoption of such systems in the eastern United States, and offers some solutions to move such systems forward through policy and educational efforts. These ideas were first presented at a symposium as part of the 2011 Annual Conference of the Soil and Water Conservation Society in Washington, DC.

Phaedranassa tunguraguae is an IUCN endangered plant species endemic to a single valley in the Ecuadorian Andes. We estimate the levels of genetic differentiation across the geographic distribution of P. tunguraguae using 12 microsatellite loci. We discuss factors that might influence the genetic structure of this species. Genetic distance was used to evaluate relationship among populations and geographic patterns. Bayesian methods were used to investigate population structure, migration, evidence of recent bottlenecks, and time of divergence. The 7 populations form 2 genetic clusters. These clusters show highly significant differentiation between them, along with isolation by distance. Allele richness decreases from the most diverse westernmost population to the least diverse easternmost population. The species overall shows an excess of homozygotes, with highest levels of inbreeding in the easternmost population. We found evidence of recent bottleneck events. Migration rates were in general low but were higher between populations within each of the clusters. Time of divergence between populations was related to historical volcanic activity in the area. Based on our results, we propose 2 management units for P. tunguraguae.

The results support a model in which (a) higher childhood participation in nature-based activities increased motivation and mitigation strategies, (b) constraints decreased state park visitation and also triggered the use of mitigation strategies that in turn increased state park visits, and (c) higher levels of motivation improved efforts to negotiate constraints and visit more. Consistent with the main hypothesis, the more nature-based activities people participate in during childhood, the more they desire such activities and are able to mitigate constraints to participation, and consequently, the higher the level of participation, as an adult. The results suggest a rather indirect association between childhood participation in nature-based activities and adulthood participation in such activities.

Occasionally, fermented cucumbers spoil after the primary fermentation is complete. This spoilage has been characterized by decreases in lactic acid and a rise in brine pH caused by microbial instability. Objectives of this study were to determine the combined effects of NaCl and pH on fermented cucumber spoilage and to determine the ability of lactic acid bacteria (LAB) spoilage isolates to initiate lactic acid degradation in fermented cucumbers. Cucumbers fermented with 0%, 2%, 4%, and 6% NaCl were blended into slurries (FCS) and adjusted to pH 3.2, 3.8, 4.3, and 5.0 prior to centrifugation, sterile-filtration, and inoculation with spoilage organisms. Organic acids and pH were measured initially and after 3 wk, 2, 6, 12, and 18 mo anaerobic incubation at 25 degree C. Anaerobic lactic acid degradation occurred in FCS at pH 3.8, 4.3, and 5.0 regardless of NaCl concentration. At pH 3.2, reduced NaCl concentrations resulted in increased susceptibility to spoilage, indicating that the pH limit for lactic acid utilization in reduced NaCl fermented cucumbers is 3.2 or lower. Over 18 mo incubation, only cucumbers fermented with 6% NaCl to pH 3.2 prevented anaerobic lactic acid degradation by spoilage bacteria. Among several LAB species isolated from fermented cucumber spoilage, Lactobacillus buchneri was unique in its ability to metabolize lactic acid in FCS with concurrent increases in acetic acid and 1,2-propanediol. Therefore, L. buchneri may be one of multiple organisms that contribute to development of fermented cucumber spoilage. Practical Application: Microbial spoilage of fermented cucumbers during bulk storage causes economic losses for producers. Current knowledge is insufficient to predict or control these losses. This study demonstrated that in the absence of oxygen, cucumbers fermented with 6% sodium chloride to pH 3.2 were not subject to spoilage. However, lactic acid was degraded by spoilage microorganisms in reduced salt, even with pH as low as 3.2. Efforts to reduce salt in commercial brining operations will need to include control measures for this increased susceptibility to spoilage. Lactobacillus buchneri was identified as a potential causative agent and could be used as a target in development of such control measures.

Inoculated lettuce was either not dried or dried for 30 min, 60 min, or 120 min, under either static air or moving air. Washing iceberg lettuce with 500 ppm oregano oil for 1, 5, and 10 min reduced the population of Salmonella spp. by (respectively) 1.3, 1.65, and 2.28 log cfu/g following the most challenging inoculation conditions, an inoculum drying period of 2 h under moving air. Across all inoculation conditions, increasing the treatment time significantly increased the reductions in the populations of Salmonella spp. (P 0.05). The results obtained in this study suggest that oregano oil can effectively reduce populations of Salmonella attached to lettuce leaf surfaces. Practical Application: The use of essential oils as an antimicrobial treatment can help to ensure the safety of leafy green products. As used in this study, oregano oil effectively reduced Salmonella spp., even after the pathogen had dried onto the lettuce leaves. Treatments that incorporate oregano oil therefore hold promise as a biocide treatment for process and packaged lettuce.

This disease is caused by the bacterial pathogen Xylella fastidiosa and is transmitted by xylem-feeding insects. Previous research suggested that retaining, rather than roguing, ALSD-affected trees may be more economically beneficial because ALSD-affected trees produced a reasonable yield and did not die over a 3-year period. Because almond orchards are kept in production for approximately 25 years, longer-term data are needed to fully evaluate the merits of retaining ALSD-affected trees. Extension of yield evaluations from 3 to 5 years demonstrated that yield loss due to ALSD was consistent over 5 years, with yields of ALSD-affected trees reduced by 20 and 40% compared with unaffected trees for 'Nonpareil' and 'So-nora', respectively. To assess risk of ALSD-affected trees serving as a source of inocula for secondary (tree-to-tree) spread and to evaluate vitality of ALSD-affected trees, previous surveys of two orchards were extended from 3 to 6 or 7 years. The relationship between disease incidence (percentage of trees infected) and survey year was linear for all cultivars examined at both orchards. Furthermore, at each orchard, the spatial location of infections detected after the first survey was random with respect to the spatial location of infections identified during the first survey, suggesting that ALSD-affected trees retained in orchards did not serve as a source for secondary spread. Over the 6- to 7-year study period, death of ALSD-affected trees was rare, with only 9% of ALSD-affected trees dying. Because orchards used in this study had relatively high disease incidence. 61 orchards containing Sonora were surveyed to determine typical levels of ALSD incidence. ALSD was widespread, with at least one infected tree in 56% of orchards surveyed, but incidence was typically low (mean incidence = 0.47%). Collectively, the results suggest that retaining ALSD-affected trees may be economically beneficial in older orchards.

In this study, the presence of Pib was determined in 164 rice germplasm accessions from a core subset of the National Small Grains Collection utilizing DNA markers and pathogenicity assays. The presence of Pib was evaluated with two simple sequence repeat (SSR) markers and a dominant marker (Pib-dom) derived from the Pib gene sequence. Pathogenicity assays using two avirulent races (IE1k and IB1) and a virulent race (IB54) were performed to verify the resistance responses of accessions. Of the 164 accessions evaluated, 109 contained the Pib gene as determined using both SSR markers and pathogenicity assays, albeit different haplotypes were detected. The remaining 52 germplasm accessions were different in their responses to the blast races IB54, IE1k, and IB1, thus indicating the presence of R gene(s) other than Pib. The accessions characterized in this study could be used for marker-assisted breeding to improve blast resistance in indica and japonica cultivars worldwide.

AN - 1028032725; 16909554 AB - A century of fire suppression has created unnaturally dense stands in many western North American forests, and silviculture treatments are being increasingly used to reduce fuels to mitigate wildfire hazards and manage insect infestations. Thinning prescriptions have the potential to restore forests to a more historically sustainable state, but land managers need to be aware of the potential impacts of such treatments on invasion by exotic plants. However, the effects of these activities on the introduction and spread of invasive plants are not well understood. We evaluated noxious weed occurrence over a 9-year period (2001-2009) following thinning and burning treatments in a lodgepole pine forest in central Montana. Surveys were made in the treatment units and along roads for two shelterwood-with-reserve prescriptions, each with and without prescribed burning, burned only, and untreated controls. Five species listed as noxious weeds in Montana were recorded: spotted knapweed (Centaurea stoebe), oxeye daisy (Leucanthemum vulgare), Canada thistle (Cirsium arvense), common tansy (Tanacetum vulgare), and houndstongue (Cynoglossum officinale). With the exception of Canada thistle, noxious weeds were confined to roadsides and did not colonize silvicultural treatment areas. Roadside habitats contributed more to the distribution of noxious plant species than did silvicultural treatments in this relatively uninvaded forest, indicating the importance of weed control tactics along roads and underscoring the need to mitigate exotic plant dispersal by motorized vehicles. In addition, these findings suggest that roadways should be considered when evaluating the potential for invasion and spread of exotic plants following forest restoration treatments.

We profiled changes in membrane lipids in two isogenic wheat lines: a susceptible line and its backcrossed offspring containing the resistance gene H13. Our results revealed a 32 to 45% reduction in total concentrations of 129 lipid species in resistant plants during incompatible interactions within 24 h after HF attack. A smaller and delayed response was observed in susceptible plants during compatible interactions. Microarray and real-time polymerase chain reaction analyses of 168 lipid-metabolism-related transcripts revealed that the abundance of many of these transcripts increased rapidly in resistant plants after HF attack but did not change in susceptible plants. In association with the rapid mobilization of membrane lipids, the concentrations of some fatty acids and 12-oxo-phytodienoic acid (OPDA) increased specifically in resistant plants. Exogenous application of OPDA increased mortality of HF larvae significantly. Collectively, our data, along with previously published results, indicate that the lipids were mobilized through lipolysis, producing free fatty acids, which were likely further converted into oxylipins and other defense molecules. Our results suggest that rapid mobilization of membrane lipids constitutes an important step for wheat to defend against HF attack.

However, pots may also contain weeds. In this research, the foliage of 14 common weeds of containerized plant culture was inoculated with P. ramorum to determine susceptibility of aboveground parts. Three species were found to develop leaf lesions: northern willowherb (Epilobium ciliatum), fireweed (Chamerion angustifolium), and a fern (Pteris cretica). Weed roots from 11 species were inoculated to see if P. ramorum could persist on roots, and P. ramorum was isolated from most plant roots 1 month after inoculation when the washed roots were plated on selective medium; they were recovered only to a minor extent from surface-sterilized roots of weeds. Additional experiments were done to collect and sample runoff from pots containing inoculated plants to see if inoculum was produced on weed roots. In these experiments, little inoculum was found in runoff from root-inoculated weeds compared to Viburnum tinus. Percent root colonization recorded from washed roots was significantly greater in Viburnum compared to the weeds, and weeds that were foliar hosts had greater root colonization than weeds that were not.

AN - 1028030953; 16829212 AB - Current methods in DNA technology can detect single nucleotide polymorphisms with measurable accuracy using several different approaches appropriate for different uses. If there are even single nucleotide differences that are invariant markers of the species, we can accomplish identification through rapid DNA-based tests. The question of whether we can reliably detect and identify species of Aspergillus and Penicillium turns mainly upon the completeness of our alpha taxonomy, our species concepts, and how well the available DNA data coincide with the taxonomic diversity in the family Trichocomaceae. No single gene is yet known that is invariant within species and variable between species as would be optimal for the barcode approach. Data are published that would make an MLST approach to isolate identification possible in the most well-studied clades of Aspergillus and Penicillium.

A large plasmid carried by STEC O145:NM strain 83-75 and named pO145-NM was sequenced, and the genes were annotated. pO145-NM is 90,103bp in size and carries 89 open reading frames. Four genes/regions in pO145-NM encode for STEC virulence factors, including toxB (protein involved in adherence), espP (a serine protease), katP (catalase peroxidase), and the hly (hemolysin) gene cluster. These genes have also been identified in large virulence plasmids found in other STEC serogroups, including O26, O157, O111, and O103. pO145-NM carries the espP alpha subtype that is associated with STEC strains that cause more severe disease. Phylogenetic analyses of HlyB, EspP, and ToxB in various STEC strains showed a high degree of similarity of these proteins in E. coli serotypes O145:NM, O26:H11/H-, O111:NM/H-, and O157:H7 potentially placing these STEC into a related group.

Information on drip-tubing positioning, irrigation strategies, and wetted soil area is needed to increase rainwater effectiveness when well capacities are inadequate to meet full irrigation requirements. Time and resources necessary to test SDI strategies for different conditions through field experimentation is too large. However, a mechanistic model such as Hydrus-2D can quantify the effect of different installation geometries and irrigation strategies. Our objective was to experimentally validate the Hydrus-2D in an Amarillo soil in THP so that the model can be used to evaluate different irrigation frequency and timing strategies for SDI cotton. Results showed that Hydrus-2D simulated volumetric soil water content within plus or minus 3% of measured values, and simulation bias represented the smaller portion of the simulation error, indicating that the model can be used to evaluate irrigation strategies.

Although poorly understood, aspects of the insect's salivary physiology may facilitate both xylem-feeding and transmission of plant pathogens. Xylella fastidiosa is a xylem-limited bacterium that causes Pierce's disease of grape and other scorch diseases in many important crops. X. fastidiosa colonizes the anterior foregut (precibarium and cibarium) of H. vitripennis and other xylem-feeding vectors. Bacteria form a dense biofilm anchored in part by an exopolysaccharide (EPS) matrix that is reported to have a beta -1,4-glucan backbone. Recently published evidence supports the following, salivation-egestion hypothesis for the inoculation of X. fastidiosa during vector feeding. The insect secretes saliva into the plant and then rapidly takes up a mixture of saliva and plant constituents. During turbulent fluid movements in the precibarium, the bacteria may become mechanically and enzymatically dislodged; the mixture is then egested back out through the stylets into plant cells, possibly including xylem vessels. The present study found that proteins extracted from dissected H. vitripennis salivary glands contain several enzyme activities capable of hydrolyzing glycosidic linkages in polysaccharides such as those found in EPS and plant cell walls, based on current information about the structures of those polysaccharides. One of these enzymes, a beta -1,4-endoglucanase (EGase) was enriched in the salivary gland protein extract by subjecting the extract to a few, simple purification steps. The EGase-enriched extract was then used to generate a polyclonal antiserum that was used for immunohistochemical imaging of enzymes in sharpshooter salivary sheaths in grape. Results showed that enzyme-containing gelling saliva is injected into xylem vessels during sharpshooter feeding, in one case being carried by the transpiration stream away from the injection site. Thus, the present study provides support for the salivation-egestion hypothesis.

The production of GABA by lactic acid starter bacteria would enhance the functionality of fermented dairy foods including cheeses and yogurt. The survey of 42 strains of the yogurt starter culture Streptococcus thermophilus by PCR techniques indicated the presence of a glutamate decarboxylase gene (gadB) in 16 strains. DNA sequencing data indicated that the GAD/GABA antiporter locus (gadB/gadC) in GAD super(+) S. thermophilus strains is flanked by transposase elements (5' and 3') and positioned between the luxS (5') and the HD-superfamily hydrolase genes (3'). The PCR amplification product of a ca. 2-kb genomic fragment that included the gadB and its putative promoter region was inserted into a shuttle vector, which was used to transform Escherichia coli DH5 alpha . Subsequently, the recombinant plasmid pMEU5a-1/gadB (7.24 kb) was electrotransformed into the GAD-negative strain S. thermophilus ST128. The ST128 transformants carrying the plasmid-encoded gadB produced functional GAD enzyme as evidenced by the conversion of glutamate to GABA at a rate similar to strains with the gadB/gadC operon located on the chromosome. The results demonstrated the potential to impart to non-GABA-producing strains of S. thermophilus and other lactic acid bacteria the GAD super(+) phenotype that improves their appeal in possible applications in the development of health-promoting functional foods.

Unfortunately, meaningful control of invasive species is often difficult. Here, we present results concerning the effects of invasion by a non-native, N sub(2)-fixing tree, Falcataria moluccana, on native-dominated forests of American Samoa and the response of invaded forests to its removal. We sampled species richness, seedling and stem densities, biomass, and soil inorganic N status in native-dominated forests, and in forests invaded by F. moluccana where it was subsequently removed. While total biomass of intact native forests and those invaded by F. moluccana did not differ significantly, greater than 60% of the biomass of invaded forest plots was accounted for by F. moluccana, and biomass of native species was significantly greater in intact native forests. Biomass of native Samoan tree species following removal of F. moluccana accumulated rapidly from 128 Mg ha super(-1) immediately after tree girdling treatment to 185 Mg ha super(-1) following 8 years of post-removal recovery, at which point biomass of F. moluccana-removal plots did not differ significantly from native-dominated forest plots. Native trees exhibiting early successional traits accounted for a large portion of aboveground biomass in these forests where frequent large-scale disturbance events (i.e., tropical cyclones) are a salient feature. We suspect that this is the single most important reason why F. moluccana removal is a successful management strategy; once F. moluccana is removed, native tree species grow rapidly, exploiting the legacy of increased available soil N and available sunlight. Seedling densities of F. moluccana were high in invaded forest stands but effectively absent following only 3 years of forest recovery; a result likely due to the shade cast by reestablishing native trees. Although F. moluccana is a daunting invasive species, it exhibits characteristics that make it vulnerable to successful control: it is easily killed by girdling or herbicides, and its seeds and seedlings do not tolerate shade. These characteristics, combined with the important capacity for rapid growth exhibited by many of Samoa's native trees, provide conditions and opportunities for successful, long-term control of F. moluccana across lowland forests of American Samoa. Caution should be exercised, however, in anticipating comparable management success in the control of F. moluccana elsewhere, as post-removal responses of invaded forest communities may differ dramatically from what has been documented in American Samoa.

AN - 1021259371; 22526926 AB - The adverse effects of Cr(III), Cr(VI), and Ni(II) expressed as root and shoot growth inhibition, metal accumulation and translocation throughout plants, and genotoxicity study were examined. To examine phytoxicity and metal accumulation, Vicia sativa, Raphanus sativus, Zea mays and Sinapis alba plants were used. Except for S. alba root growth inhibition, Ni had the strongest inhibitory effect on root and shoot growth. The inhibitory rank order based on IC₅₀ values was Ni(II) > Cr(VI) > Cr(III). Z. mays was the least sensitive to all metals. While the accumulation of Cr was higher in the roots than the upper plant parts, Ni transport to shoots was at least two times higher than that of Cr. The highest accumulation of Cr was found in Z. mays and that of Ni in V. sativa and Z. mays roots. For all plants, the translocation factor was higher for Cr(VI) than for Cr(III). The translocation factor for Ni was several times higher than those of Cr. For mutagenicity assay, root tips of V. sativa, R. sativus and Z. mays were used. All metals exerted a significant increase of chromosomal aberrations and the rank order of aberrations was: Cr(VI) > Ni(II) > Cr(III). Genotoxic effects of metals were also determined by analysis of micronuclei frequency in the pollen tetrads of Tradescantia plants. None of metals significantly stimulated micronuclei frequency and the genotoxic effect decreased in the following order: Cr(VI) ≥ Ni(II) > Cr(III).

Measurements have shown that environmental conditions and silage properties strongly influence emission rates, making it difficult to assess the contribution of silage in VOC emission inventories. In this work, we present an analytical convection-diffusion-dispersion model for predicting emission of VOCs from silage. It was necessary to incorporate empirical relationships from wind tunnel trials for the response of mass transfer parameters to surface air velocity and silage porosity. The resulting model was able to accurately predict the effect of temperature on ethanol emission in wind tunnel trials, but it over-predicted alcohol and aldehyde emission measured using a mass balance approach from corn silage samples outdoors and within barns. Mass balance results confirmed that emission is related to gas-phase porosity, but the response to air speed was not clear, which was contrary to wind tunnel results. Mass balance results indicate that alcohol emission from loose silage on farms may approach 50% of the initial mass over six hours, while relative losses of acetaldehyde will be greater.

Sodium bentonite (SB) gel and foam coatings were evaluated in burn tests for their ability to protect a sample of commercial lap siding from intense heat (42kW/m2). Starch was added to some treatments to determine whether it stabilized the coating and prevented vertical slumping. A commercial fire protection gel coating was included in the study for comparison. Coatings containing starch and the SB gel sample had negligible slumping during burn tests while the commercial gel and the SB foam slumped severely during the test. In rheology studies, samples containing starch had higher G' (elastic modulus), G double prime (viscous modulus), and higher yield stress than the commercial gel or SB samples without starch. Surprisingly, the samples containing starch heated more slowly than samples without starch. This could be explained, in part, by the continuous boundary layer (crust) that formed during the burn test that shielded the substrate surface from direct heat exposure, minimized the exposed surface area, and, initially, lowered water vapor flux. Drying tests were performed at 44 degree C to determine how long the coatings could remain hydrated under severe conditions. The SB gel coatings remained hydrated longer than the SB foam samples. Starch prolonged the drying time (reduced evaporation rate) for both the SB foam and gel samples.

The fuels that feed these crown fires are mostly live, green foliage. Unfortunately, little is known about how live fuels combust. To understand how live fuels burn, piloted ignition experiments were performed with lodgepole pine and Douglas-fir. The thermal behavior (thick versus thin) of both live and dead needles was explored. Both live and dry needles were shown to behave as thermally intermediate solids in this apparatus. Additionally, samples were collected throughout the growing season to take advantage of the natural variation in moisture content and chemical composition. This data set was then compared to several correlations found in the literature to determine whether live fuel ignition can be predicted by moisture content alone and to test the applicability of these models to the wildland fire problem. Many of the correlations from the literature for ignition time with moisture content fail to capture the trends with live fuels. A linear regression of the ignition time with moisture content only predicts 74-80% of the variability suggesting that there is another mechanism controlling ignition time of live fuels. Based on the hypothesized difference in water storage between live and wet dead fuels, the chemical composition of the live needles was included in an empirical model for ignition time. Including chemical composition improved the prediction accuracy for Douglas-fir needles only. Because the thermal properties of live foliage are largely unknown, it is possible that the predictions from more physically-based models would show improvement with more accurate values of density, thermal conductivity, and specific heat.

Prescribed fire is increasingly used as a tool in oak ecosystem restoration, with the goal of reducing competition, and creating light and seedbed conditions conducive to germination and growth of oak seedlings. Yet, oak seedling establishment is dependent on the presence of viable acorns, which may be vulnerable to prescribed fire. We assessed the effect of prescribed burning and fire temperature on the viability of white oak and northern red oak acorns placed on the leaf litter surface, in the duff, or in the mineral soil during five winter prescribed burns in southern Appalachian upland hardwood forests. Fire temperatures varied among acorn plots, ranging from =204 degree C showed high mortality levels, with mortality virtually 100% at temperatures >=260 degree C. Fall burns, especially after a heavy acorn crop, could result in high acorn mortality, potentially impacting oak regeneration from seedlings for many years given erratic acorn production patterns among years and species. Frequent burning that reduces litter and duff depth could compromise availability of 'safe sites' where acorns are insulated from high fire temperatures. When oak ecosystem restoration is a goal, land managers should consider the timing and size of acorn crops, as well as the forest floor condition when determining the timing and frequency of prescribed burning.

Cover crops grown between maturity and planting of these crops are one approach for reducing losses of NO3. In this experiment, we evaluated the effectiveness of oat (Avena sativa L.) and rye (Secale cereale L.) cover crops in reducing NO3 concentrations and loads in subsurface drainage water. The oat fall cover crop was broadcast seeded into living corn and soybean crops before harvest in late August or early September and was killed by cold temperatures in late November or early December The rye winter cover crop, which had already been used annually for four years, was planted with a grain drill after corn and soybean harvest, overwintered, grew again in the spring, and was killed with herbicides before main crop planting. These treatments were evaluated in subsurface-drained field plots with an automated system for measuring drainage flow and collecting proportional samples for analysis of NO3 concentrations from each plot. The rye winter cover crop significantly reduced drainage water NO3 concentrations by 48% over five years, but this was less than the 58% reduction observed in its first four years of use. The oat fall cover crop reduced NO3 concentrations by 26% or about half of the reduction of the rye cover crop. Neither cover crop significantly reduced cumulative drainage or nitrate loads because of variability in cumulative annual drainage among plots. Both oat and rye cover crops are viable management options for significantly reducing NO3 losses to surface waters from agricultural drainage systems used for corn and soybean production.

Transient-state, process-based model analyses offer the possibility of more efficient water and salinity management, but data are needed to evaluate the accuracy of various subcomponents of the models. In this study, tracer (Br) transport in twelve lysimeters identically packed with clayey soil materials was monitored at eight soil depths and in drainage waters. In the first phase of the experiment (the salinization phase), six of the lysimeters were irrigated with high EC waters (8.1dSm-1) and six with low EC waters (0.4dSm-1). In the second phase, all lysimeters were leached with low EC waters (0.4dSm-1). Tracer transport was very different in the high and low EC irrigation treatments, with the high EC treatment exhibiting significant tailing in the breakthrough curves. Due to the replicated experimental design, it was possible to confirm that the differences between the experimental treatments were significant and not due to random deviation. Future research aimed at placing realistic confidence levels on model predictions will allow transient-state models to reach their full potential as water and salinity management tools.

An assessment of the potential impact of climate change and elevated CO2 on irrigated corn (Zea mays L.) in the Central Great Plains of Colorado was conducted using the Root Zone Water Quality Model (RZWQM2) model. One hundred and twelve bias corrected and spatially disaggregated (BCSD) climate projections were used to generate four different multi-model ensemble scenarios of climate change: three of the ensembles represented the A1B, A2, and B1 emission scenarios and the fourth comprised of all 112 BCSD projections. Three different levels of irrigation, based on meeting 100, 75, and 50% of the crop ET demand, were used to study the climate change effects on corn yield and water use efficiency (WUE) under full and deficit irrigation. Predicted increases in mean monthly temperature during the crop growing period varied from 1.4 to 1.9, 2.1 to 3.4, and 2.7 to 5.4 degree C during the 2020s, 2050s, and 2080s, respectively, for the different climate change scenarios. During the same periods, the projected changes in mean monthly precipitation varied in the range of -4.5 to 1.7, -6.6 to 4.0 and -11.5 to 10.2%, respectively. Simulation results showed a decrease in corn yield, because the negative effects of increase in temperature dominated over the positive effects of increasing CO2 levels. The mean overall decrease in yield for the four different climate change scenarios, with full irrigation, ranged from 11.3 to 14.0, 17.1 to 21.0, and 20.7 to 27.7% during the 2020s, 2050s, and 2080s, respectively, even though the CO2 alone increased yield by 3.5 to 12.8% for the scenario representing ensembles of 112 projections (S1). The yield decrease was linearly related to the shortening of the growing period caused by increased temperature. Under deficit irrigation, the yield decreases were smaller due to increased WUE with elevated CO2. Because of the shortened crop growing period and the CO2 effect of decreasing the ET demand, there was a decrease in the required irrigation. Longer duration cultivars tolerant to higher temperatures may be one of the possible adaptation strategies. The amount of irrigation water needed to maintain the current yield for a longer duration corn cultivar, having the same WUE as the current cultivar, is projected to change in the range of -1.7 to 6.4% from the current baseline, under the four different scenarios of climate change evaluated in this research.

Especially challenging is how to retain the habitat elements for species that are typically associated with late-seral forests. We develop a regionally specific, multivariate model describing habitat selection that can be used - when linked to an institutional forest inventory program - to assess, monitor and forecast habitat conditions for a key wildlife species. We use the fisher (Martes pennanti) in northwestern California as our example and develop a predictive model for resting habitat that is created using data from the specific region where it will be used. We explore how this resting habitat model differs from a similar model developed for the Sierra Nevada and consider the implications for forest management. We developed the model using MaxEnt by comparing vegetation data at 99 randomly selected fisher resting structures on public and tribal lands in northwestern California with 883 Forest Inventory and Analysis (FIA) plots within the same ecoregion. A total of 58 alternative vegetation models were specified and the top 10 were nearly identical in their performance (Gain>1.08; Area Under the Curve [AUC]>0.89). We chose a five-variable model (canopy closure, tree age, total basal area, volume of "large" wood and basal area of hardwoods) because it included the fewest variables and included only those that could be affected by management. This model was similar to the Sierra Nevada model, but did not include topographic features (e.g., slope) nor did it include a variable representing the density of small trees. The absence of variables related to topography may make it easier for managers to affect positive change in resting habitat suitability since all variables can be influenced by management actions. Moreover, the model indicates that small trees appear to be less important (compared to southern Sierra Nevada) and therefore the probability of producing high-value resting habitat without higher fire risk is greater. We also created a spreadsheet that simplifies the process of generating habitat predictions from new data. Since metrics of stand structure and wildlife habitat are sensitive to sample design, collecting new data with FIA protocols will provide the most accurate estimates of predicted habitat with this model. Together, the Sierra Nevada and northwest California models provide managers in California a quantitative means to assess and monitor resting habitat suitability using current and future data that are part of an institutionally supported program to inventory forest vegetation.

These viroids are important quarantine pathogens for the international movement of pome germplasm. A single-step multiplex reverse transcription polymerase chain reaction assay (mRT-PCR) was developed for the simultaneous detection of these viroids. Four pairs of primers specific for each of the four viroids were used to amplify PCR products of different sizes that can be resolved by agarose gel electrophoresis. Amplification of a plant 18S rRNA was included in the assay as an internal control. Amplicons of 371 bp (AFCVd), 270 bp (ADFVd), 186 bp (ASSVd), 120 bp (PBCVd), and 844 bp (18S rRNA) were obtained in both uniplex and mRT-PCR assays. The identities of the amplification products were confirmed by sequencing. The specificities and limits of detection for all four viroids by uniplex and mRT-PCR assays were comparable. The assay was further validated using samples from pome trees inoculated with all four viroids, as well as field samples from commercial orchards in Colorado. All four viroids were detected from inoculated pear trees and up to three viroids were detected from inoculated apple trees. This is a simple, rapid and cost-effective technique to detect these four viroids in fruit trees. The procedure is especially applicable to certification and quarantine programs, where numerous samples must be tested for all four viroids.

In order to study the mechanisms of pathogenesis of this fungus, we have transformed Fog with Agrobacterium tumefaciens binary vectors containing the hygromycin B phosphotransferase (hph) gene and fluorescence reporter genes EGFP (green), EYFP (yellow) or ECFP (cyan) using the AGL-1 strain of A. tumefaciens. Hygromycin B (100 mu g/ml) resistant colonies were observed only when acetosyringone was added to the co-cultivation medium. Transformed colonies are more clearly visible when co-cultivated on cellophane membrane than on Hybond -N super(+) membrane. Transformed lines were stably maintained through four serial passages on medium containing hygromycin B, and they expressed green, yellow or cyano fluorescence. PCR with hph-specific primers and Southern blotting with an hph-specific probe were positive for Hyg super(R) lines but not for the untransformed isolate. The cyano fluorescence of the ECFP-transformed isolate was clearly distinguishable from the green autofluorescence of Gladiolus roots, signifying the potential of these lines for further histopathological investigations. Transformed lines will be useful for identifying pathogenicity related genes, screening transgenic resistance, and in studies of host-pathogen interactions.

Results revealed significant levels of polymorphism (59%) among the isolates. Even so, genetic similarity between isolates was high, ranging from 0.78 to 1.00. Clustering of similar isolates did not correlate with either geographic origin or year of collection. Pathotypes of 20 of the isolates were determined using 14 sorghum lines previously used in Brazil and the United States and 4 from Sudan. Seventeen new pathotypes were established from the 18 isolates that gave uniform and consistent reactions on all host differentials over 2 years of greenhouse testing. Differentials BTx378 and QL3 were resistant to all isolates while BTx623 and TAM428 were universally susceptible both years. Each of these lines had shown differential responses in prior studies indicating that the pathogen population has sufficient diversity to adapt rapidly to changes in resistant host lines deployed. When the 2-step pathotype classification scheme was used, the 18 isolates examined in this study were placed in four pathotype groups (A, C, D and G), which would further then be separated into ten distinct pathotypes. Common sets of differentials and a standardized nomenclature will allow for comparison to be made among pathotypes of C. sublineolum detected from different regions and also could help direct planting of appropriate sorghum lines and aid in the development of more durable forms of resistance.

We returned over a decade later to determine how these treatments affected tree growth using increment cores. There were no significant differences in tree density, basal area or tree diameters among treatments at the time of sampling. Although tree growth was consistently higher in the log-input plots and lower in the removal plots, this was true even during the 5year period before the experiment began. When growth data from this initial period were included in the model as a covariate, no differences in post-treatment tree growth were detected. It is possible that treatment effects will become apparent after more time has passed, however.

However, traditional methods for determining plant tissue N content are cumbersome, time-consuming, and destructive-and thus unsuited for rapid in situ evaluations. We therefore tested the utility of a hand-held chlorophyll meter as a means of producing in situ estimates of N in the leaves of this floating aquatic weed. The Minolta SPAD-502 chlorophyll meter provided excellent estimates (F=385.96, P<0.0001) of leaf tissue N levels. SPAD readings varied within leaves (F=78.66, P<0.0001), so average readings per leaf were used. The relationship between SPAD readings and tissue N levels was affected by the phenological stage of the leaf (F=102.79, P<0.0001), but not leaf size (F=0.75, P=0.3867). The estimates were also unaffected by fertilizer level (F=0.95, P=0.4354), but were marginally affected by herbivory (F=3.86, P=0.0505). Thus, with suitable calibration (e.g., different field sites, presence and type of herbivory) output from the SPAD-502 could be used to provide consistent estimates for the nitrogen content of E. crassipes leaves.

AN - 1020188585; 22371389 AB - The 30 month longevity, mobility and insecticidal activity of a combination of acetamiprid and bifenthrin currently marketed in the United States for the prevention of termite infestation in buildings was investigated in greenhouse and laboratory studies. Acetamiprid dissipated to below the limit of detection within 7 months of application, while bifenthrin remained in the soil at levels sufficient to kill termites for the duration of the study. Acetamiprid was detected in decreasing amounts in eluates of treated soil from months 1 to 4, while no bifenthrin was detected in eluates at any time. The treated soil remained toxic to termites for the 30 month duration of the study. Two indices of synergy between technical-grade acetamiprid and bifenthrin demonstrated that it is unlikely that there would be any synergism between the two active ingredients in the field. The presence of vegetation did not have a significant effect on the longevity of bifenthrin, except at intermediate times, where residues in the treated soil were higher in vegetated plots, depending on depth and time. Acetamiprid has a short residual time in soil, and this formulation's effectiveness beyond about 7 months against subterranean termites is due to the bifenthrin content.

AN - 1020049803; 22671856 AB - Peracetic acid (PAA) is a relatively new compound suggested for use to treat pathogens in aquaculture. It is approved for use in Europe, but not in the United States. This study determined the effectiveness of PAA for fungus control on channel catfish, Ictalurus punctatus (Rafinesque), eggs. The study consisted of five PAA concentrations (2.5, 5, 10, 15 and 20mgL(-1) ) and an untreated control in a flow-through system. A single spawn was used for each replication (N =4). Eggs were treated twice daily until the embryos developed eyes. When hatching was complete for all viable eggs, fry were counted to determine the percent survival in each treatment. Fungal growth was severe in the untreated controls resulting in 11% survival. Treatments of 2.5, 5 and 10mgL(-1) PAA were significantly different from the controls (P<0.05). The highest percent survival of hatched fry was with 5mgL(-1) PAA administered twice daily; the 2.5mgL(-1) PAA treatment had slightly less survival, but gives a higher margin of safety in case of treatment error. Very little fungus was present in treatments receiving 2.5mgL(-1) PAA or higher, and concentrations of 15 and 20mgL(-1) PAA were toxic to the eggs. The mean survivals in the 0, 2.5, 5, 10, 15 and 20mgL(-1) PAA treatments were 11%, 60%, 63%, 62%, 32% and 0%, respectively. Therefore, PAA may be a compound that merits further investigations regarding its use in U.S. aquaculture. Published 2012. This article is a US Government work and is in the public domain in the USA.

Plants were treated with ambient air, 1.4 ambient O3 and 550 ppm CO2 separately and in combination using Free Air Concentration Enrichment technology. Under ambient O3 concentrations pod yields were not significantly different among genotypes. Elevated O3 reduced pod yield for S156 (63%) but did not significantly affect yields for R123 and R331. Elevated CO2 at 550 ppm alone did not have a significant impact on yield for any genotype. Amelioration of the O3 effect occurred in the O3 + CO2 treatment. Ratios of sensitive to tolerant genotype pod yields were identified as a useful measurement for assessing O3 impacts with potential applications in diverse settings including agricultural fields.

AN - 1015245119; 22516681 AB - Cyclopamine (1) was isolated from the plant Veratrum californicum Durand (Liliacea) and identified as the teratogen responsible for severe craniofacial birth defects including cyclops in the offspring of sheep grazing on mountain ranges in central Idaho. More recently, cyclopamine (1) was found to inhibit the hedgehog (Hh) signaling pathway which plays a critical role in embryonic development and is implicated in several types of cancer. Thus, cyclopamine (1) and cyclopamine derivatives have been targeted as potential pharmaceutical treatments for certain cancers and other diseases associated with the Hh signaling pathway. A monoclonal antibody-based competitive inhibition enzyme-linked immunosorbent assay was developed to detect and measure cyclopamine (1) and cyclopamine derivatives in biological samples. The limits of detection of the assay for cyclopamine (1), 3-keto-N-aminoethyl aminocaproyl digyrocinnamoyl-cyclopamine (8), and N-(4-l-rhamnopyranosyl-1H-1,2,3-triazol-1-yl)-methylcyclopamine (11) were 2.9 pg, 0.41 pg and 2.6 pg, respectively. This assay was also found to be useful for the detection and measurement of cyclopamine (1) in sera from mice that had been dosed with cyclopamine (1). The simple ELISA method described herein demonstrates the potential of using these techniques for the rapid screening of biological samples for the presence and levels of cyclopamine (1) and other cyclopamine derivatives that are Hh inhibitors with anticancer potential.

Profiling element concentrations in genetically diverse plant populations is providing insights into the plant-environment interactions that control elemental accumulation, as well as identifying the underlying genes. The resulting molecular understanding of plant adaptation to the environment both demonstrates how soils can shape genetic diversity and provides solutions to important agricultural challenges.

Produced by Clostridium botulinum, BoNTs are classified into seven, antigenically distinct serotypes, designated A-G. The toxin acts to inhibit acetylcholine release, resulting in paralysis and death. Naturally occurring foodborne disease is most often the result of improper canning of foods, while wound botulism, associated with injection drug users, is on the rise. Because of its potency, BoNTs have also been identified as targets for use by bioterrorists. The 'gold standard' of detection of BoNTs is the mouse bioassay, an expensive and time consuming test that requires specialized equipment and trained personnel. There is a need for a rapid, sensitive diagnostic for BoNTs that could be used by minimally trained personnel in the event of a foodborne outbreak or a bioterrorist threat. Here, we describe the use of a single lateral flow device (LFD) that can detect and distinguish between BoNT/A and B, two of the four serotypes that are known to intoxicate humans and together represent >80% of naturally occurring illness. The device could detect as little as 5ng/mL of purified BoNT/A and 10ng/mL of BoNT/B in 2% and 1% milk, respectively. In undiluted apple juice, 25ng/mL of BoNT/A and 10ng/mL of BoNT/B could be detected. No cross reactivity between BoNT/A and B antibodies was observed. The LFD described here is easy to use, requires no specialized training or equipment, and can identify and distinguish between BoNT/A and /B serotypes. These attributes make this rapid diagnostic device a potentially valuable tool in the fields of food safety and homeland security.

Hydrologic management of the 500m-long, 25m-wide riverine wetland was done by adding weirs at both ends. The agrichemical mixture was amended to the wetland at the upstream weir simulating a four-hour, ~1cm rainfall event from a 16ha agricultural field. Water samples (1L) were collected every 30min within the first 4h, then every 4h until 48h, and again on days 5, 7, 14, 21, and 28 post-amendment at distances of 0m, 10m, 40m, 300m and 500m from the amendment point within the wetland for suspended solids, nutrient, and pesticide analyses. Peak sediment, nutrient, and pesticide concentrations occurred within 3h of amendment at 0m, 10m, 40m, and 300m downstream and showed rapid attenuation of agrichemicals from the water column with 79-98%, 42-98%, and 63-98% decrease in concentrations of sediments, nutrients, and pesticides, respectively, within 48h. By day 28, all amendments were near or below pre-amendment concentrations. Water samples at 500m showed no changes in sediment or nutrient concentrations; pesticide concentrations peaked within 48h but at less than or equal to 11% of upstream peak concentrations and had dissipated by day 28. Managed riverine wetlands greater than or equal to 1ha and with hydraulic residence times of days to weeks can efficiently trap agricultural runoff during moderate (1cm) late-spring and early-summer rainfall events, mitigating impacts to receiving rivers.

This study aims to link two different scales of soil moisture estimates by upscaling single point measurements to field averages for representing field-scale agricultural areas ( similar to 2ha) located within the Upper Cedar Creek Watershed in northeastern Indiana. Several statistical methods, mainly focusing on cumulative distribution function (CDF) matching, are tested to upscale point measurements to spatially representative soil moisture. These transforming equations are termed observation operators. The CDF matching is found to be the most successful upscaling method followed by the mean relative difference method using temporally stable point measurements. This study also tests the temporal and spatial (horizontal and vertical) transferability of the different observation operators. Results indicate that the two observation operators from the CDF matching approach and the mean relative difference method using a temporally stable location are transferable in space, but not in time. Rainfall characteristic is most likely the dominant factor affecting the success of observation operator transferability. In addition, the CDF matching approach is found to be an effective method to deduce spatial variability (standard deviation) of soil moisture from single point measurements.

P4 AN - 1024663872; 16860949 AB - Cyclodextrin glycosyltransferase (CGTase, EC 2.4.1.19) from a thermophilic anaerobic bacterium, Thermoanaerobacter sp. P4, was purified by ammonium sulfate precipitation followed by alpha -cyclodextrin epoxy activated-sepharose 6B column chromatography. Enzyme was purified 141 fold and had the specific activity of 143.8 U/mg proteins. Purification yields after ammonium sulfate precipitation and affinity chromatography were 25.8 and 17.8%, respectively. SDS-PAGE analysis showed that enzyme was purified successfully and had a single band. Molecular weight of the enzyme was determined as 68.7 kDa. The enzyme had optimum cyclization activity at 80 to 90 degree C and hydrolyzing activity at 90 degree C and maintained 87 and 95% of these activities at 95 degree C, respectively. Optimal pH was found as 7.0. It retained full activity at 80 degree C for 4 h. Enzyme was strongly inhibited by HgSO sub(4) and AgNO sub(3). Addition of 1 mM CaCfe increased the enzymatic activity up to 7%. This novel enzyme could be a good candidate for industrial applications according to its characteristic found in the current study.

2016-109084 AB - Iceland has extensive areas with intense aeolian processes, in spite of humid climate. We measured wind erosion in a 110 km (super 2) heterogeneous sandy area near the Mt. Hekla volcano in South Iceland. The area is sparsely vegetated and covered by volcanic materials. Measurements were made during two summer seasons in 2008-2009 with dust traps at 25 locations employing a "single dust trap method" after characterizing sediment height profiles. Sets of electronic equipment that measured wind erosion and several weather parameters were placed at two locations. The results show a large variation in sediment transport with maximum transport in storms ranging from 0 to 1788 kg m (super -1) at each site and maximum average transport during storm reaching 244 kg m (super -1) h (super -1) . The aeolian transport each summer ranged from 1 to 2981 kg m (super -1) . Amount of loose sandy sediments on the surface, sediment texture and proximity to water channels are important factors explaining site differences. Wind erosion was most intense in the north-eastern part of the area, with >80% loose sand on the surface but less intense closest to the volcano where coarse pumice characterizes the surface. The research shows a pathway of sediment transport on a landscape scale with north-easterly winds, into the Thjorsa river, enhanced by landscape characteristics and seasonally active water channel. Pumice grains >8 mm in diameter were transported by saltation. Grains >1 mm were commonly >20% of materials collected at 30 cm height, which is explained by low density of the volcanic materials and high wind velocities.

The U.S. module tracks regional timber markets, timber harvests by species group, and timber product outputs in greater detail than does the global model. This hybrid approach provides detailed regional market analysis for the United States although retaining the broader global market analysis. We describe how the U.S. Forest Products Module is structured within the global model and show projections based on Intergovernmental Panel on Climate Change scenarios with long-range assumptions about economic activity, population growth, and wood energy demands. Results show that real prices for industrial roundwood would increase as a result of significant global expansion in wood energy demands. Expansion of global wood energy demands would influence the comparative economic advantages of U.S. versus foreign producers, with U.S. producers gaining some comparative advantages and increased net exports in scenarios where average foreign industrial roundwood prices are projected to increase more than in the United States. These results suggest that national wood energy policies should consider how the impacts of wood energy use on domestic forest product markets depend on trends in global forest product markets. Le module du secteur forestier aux Etats-Unis (USFPM) a eteelaborea partir du modele mondial du secteur forestier (GFPM-Global Forest Products Model). Le USFPM permet de suivre l'evolution des marches regionaux du bois d'oeuvre, des recoltes de bois d'oeuvre par groupe deessences et des produits derives de fa con plus detaillee que le modele mondial. Ce modele hybride offre une analyse detaillee des marches regionaux aux Etats-Unis tout en conservant une analyse generale du marche mondial. Dans le present article, nous decrivons la structure du module du secteur forestier aux Etats-Unis par rapport au modele mondial du secteur forestier et presentons des previsions formulees d'apres des scenarios elabores par le Groupe d'experts intergouvernemental sur levolution du climat (GIEC) et renfermant des hypotheses long terme sur l'activiteeconomique, la croissance de la population et la demande de bois energie. Nos resultats indiquent que les prix reels du bois rond industriel risquent d'augmenter en raison de la croissance substantielle de la demande mondiale de bois energie. Cette croissance aurait des repercussions sur les avantages comparatifs des producteurs americains par rapport aux producteurs etrangers, mais les producteurs americains obtiendraient certains avantages comparatifs et une hausse des exportations nettes dans les scenarios ou les prix moyens du bois rond industriel etranger augmenteraient par rapport aux prix observes aux Etats-Unis.

J. Torrey Bot. Soc. 139: 149-166. 2012.--Rhododendron maximum L. is an evergreen, clonal shrub that forms a dominant sub-canopy layer and is a key species in southern Appalachian forests. We investigated the age and distribution of R. maximum across the Coweeta Basin, a 1626 ha watershed in western North Carolina. We selected 16 perennial, second-order streams and used a Global Positioning System to establish site boundaries and map the coverage of R. maximum across the hillslopes from stream to ridge. In each site, three transects from stream edge to the ridge were used to measure diameters of overstory trees ( greater than or equal to 2.5 cm dbh), tree saplings (< 2.5 cm dbh) and shrubs including R. maximum stems. Along each transect, we cut cross-sections of R. maximum ramets and extracted increment cores from nearest neighbor trees to determine ages. The 16 sites ranged in size from 0.3 to 1.9 ha depending on the distance from stream to ridge. Rhododendron maximum cover ranged from 25 to 100% and ages ranged from 6 to 120 years. Rhododendron maximum establishment year showed a skewed unimodal distribution with the peak establishment occurring between 1928 and 1940. Although the R. maximum age and distance-from-stream relationship was statistically significant, the relationship was not meaningful as distance-from-stream only explained 2.6% of the variation in R. maximum age (r super(2) = 0.026, P = 0.0003, n = 487). Distance from stream only explained 4.2% of the variation in overstory tree age (r super(2) = 0.042, P = 0.0015, n = 237). It appears that R. maximum has not expanded upslope over the last 100 years; rather the ranges in sizes and ages suggest that ramets are recruiting under established R. maximum canopies particularly in the wetter, near stream locations.

Knowing this information can assist resource managers in better targeting problem species and implementing appropriate management actions. We planted and monitored ponderosa pine (Pinus ponderosa Douglas ex Lawson & C. Lawson) and narrow-leaf cottonwood (Populus angustifolia E. James) seedlings in metal stock tanks occupied by deer mice or house mice to assess the potential for damage by these rodents. Both species damaged leaves and stems of cottonwood seedlings, but house mice did more damage. House mouse damage resulted in mortality of over half of the cottonwood seedlings, whereas deer mice caused a much lower level of seedling mortality. Only slight damage was done by either species to pine seedlings. Neither species damaged the roots of seedlings, despite the extensive burrowing by house mice. Although voles are often considered to be the primary rodent species causing seedling damage, we have shown that deer mice and especially house mice could also cause substantial damage to deciduous seedlings. However, our work suggests that rodent control to prevent damage to conifer seedlings might not be warranted in general unless there are extenuating circumstances and the species causing the damage are identified to assist with targeting control methods more precisely.Original Abstract: Bien qu'on sache que les campagnols peuvent endommager les semis, on ne sait pas dans quelle mesure la souris sylvestre (Peromyscus spp.) et la souris domestique (Mus musculus Linnaeus, 1758) causent egalement des dommages aux semis. La reponse a cette question pourrait aider les gestionnaires a mieux cibler les especes problematiques et a mettre en oeuvre des actions d'amenagement appropriees. Nous avons mis en terre et suivi des semis de pin ponderosa (Pinus ponderosa Douglas ex Lawson & C. Lawson) et de peuplier a feuilles etroites (Populus angustifolia E. James) dans des bacs de rangement en metal occupes par des souris sylvestres ou des souris domestiques pour evaluer les dommages que peuvent causer ces rongeurs. Les deux especes ont cause des dommages aux feuilles et a la tige des peupliers a feuilles etroites. Les dommages causes par la souris domestique etaient nettement plus marques, provoquant la mort de plus de la moitie des semis de peuplier a feuilles etroites tandis que la souris sylvestre causait beaucoup moins de mortalite. Les deux especes de souris ont seulement cause des dommages mineurs aux semis de pin. Aucun dommage aux racines n'a ete observe, meme si la souris domestique creusait beaucoup de terriers. Bien que les campagnols soient souvent percus comme l'espece de rongeur qui cause le plus de dommages aux semis, notre etude montre que la souris sylvestre et surtout la souris domestique peuvent aussi causer des dommages considerables aux semis des essences feuillus. Toutefois, nos resultats indiquent que la repression des rongeurs pour prevenir les dommages aux semis des coniferes n'est en general pas justifiee, sauf dans des cas speciaux et lorsque les especes qui causent les dommages sont identifiees de maniere a mieux cibler les methodes de repression.

Lindl. ex Hildebr.) trees planted in a common garden study near Camino, California, that represented five geographic provenances of this species. The objective was to determine if there is a differential lesion length response of white fir provenances with respect to provenance. We found a significant (P < 0.019) difference between the provenances from Arizona and those of eastern Nevada origins 28 days after inoculation. There was a significant interaction between the two T. symbioticum isolates and season of inoculation. Fall inoculations tended to have smaller lesions than those in the spring but this varied by isolate in that the one from eastern Nevada tended to produce longer lesions in the spring (P = 0.0001) whereas the isolate from the Camino plantation did not differ between spring and fall (P = 1.000). There is evidence for genetic variability relative to white fir provenance lesion length in response to T. symbioticum inoculation, and in future studies, isolate variability should also be taken into account.Original Abstract: Nous avons inocule le champignon Trichosporium symbioticum Wright associe au scolyte sculpteur du sapin (Scolytus ventralis LeConte) sur 56 sapins concolores (Abies concolor (Gordon & Glend.)

L'objectif consistait a determiner si la longueur des lesions varie selon la provenance du sapin concolore. Nous avons observe une difference significative (P < 0,019) entre les provenances de l'Arizona et celles de l'est du Nevada 28 jours apres l'inoculation. Il y avait une interaction significative entre les deux isolats de T. symbioticum et la saison d'inoculation. Les inoculations faites a l'automne avaient tendance a produire de plus petites lesions que celles du printemps mais cela variait selon l'isolat : l'isolat de l'est du Nevada avait tendance a produire des lesions plus longues au printemps (P = 0,0001) tandis que les lesions produites par l'isolat provenant de la plantation de Camino avaient les memes dimensions (P = 1,000) que l'inoculation ait eu lieu au printemps ou a l'automne. Il y a des indices que la longueur des lesions en reaction a l'inoculation de T. symbioticum reflete la variabilite genetique des provenances de sapin concolore et les etudes ulterieures devraient egalement tenir compte de la variabilite des isolats.

Laboratory studies indicated the potential of wood-decay fungi to restore lost Ca. This study presents changes in concentration of Ca, Mg, and K in sapwood of red spruce (Picea rubens Sarg.), red maple (Acer rubrum L.), eastern hemlock (Tsuga canadensis (L.) Carriere), and paper birch (Betula papyrifera Marshall) during the decay process at two experimental forests for 12 years and to compare concentrations of exchangeable Ca, Mg, and Al in decayed wood residues at 10 and 12 years with those in the forest floor. Significant loss of mass indicated by decreasing wood density occurred after 2-8 years in conifers and after only 2 years in hardwoods. A significant gain in wood K was observed at 2 years followed by a significant loss at 8 years. A negligible gain in Ca concentration occurred at 2 years and a substantial gain at 8 years. Observed changes in Mg concentration were variable. No significant difference in exchangeable Ca concentration was observed between decayed wood residue of spruce and maple and the forest floor. However, decayed wood residue had a much lower Al concentration and molar Al/Ca ratio, a condition characteristic of sites with high root-available Ca.Original Abstract: La diminution du Ca disponible pour les racines dans les sols des forets nordiques exposees a plusieurs decennies de depots acides accrus affecte la sante et la productivite de la foret.

Cette etude presente l'evolution de la concentration de Ca, Mg et K dans le bois d'aubier de l'epinette rouge (Picea rubens Sarg.), de l'erable rouge (Acer rubrum L.), de la pruche du Canada (Tsuga canadensis (L.) Carriere) et du bouleau a papier (Betula papyrifera Marshall) durant le processus de decomposition dans deux forets experimentales pendant 12 ans et compare les concentrations de Ca, Mg et Al echangeables dans les debris ligneux apres 10 et 12 ans a celles qu'on retrouve dans la couverture morte. Une perte importante de masse, comme le revele la diminution de la densite du bois, est survenue apres 2 a 8 ans chez les coniferes et apres seulement deux ans chez les feuillus. Un gain important en K dans le bois a ete observe apres 2 ans suivi par une perte importante apres 8 ans. Un gain negligeable dans la concentration de Ca est survenu apres 2 ans suivi d'un gain substantiel apres 8 ans. Les changements observes dans la concentration de Mg etaient variables. Aucune difference significative n'a ete observee dans la concentration de Ca echangeable entre les debris ligneux caries d'epinette, d'erable et la couverture morte. Cependant, les debris ligneux caries avaient une concentration en Al et un rapport molaire Al/Ca beaucoup plus faibles, une situation caracteristique des stations ou la disponibilite de Ca pour les racines est elevee.

As expected, sufficient resources and capacity for forest policy implementation are crucial for attaining governmental forest policy objectives, but innovative arrangements for promoting, enforcing, and verifying policy compliance can compensate for limited regulatory resources and processes. The findings also indicate that: the level of governmental commitment to sustainable forest management (SFM) was as important as total funding levels; a mix of government rules and incentives enhanced adoption of SFM; the incorporation of professional forest regents offset limited agency capacity; and forest certification enhanced SFM on forest concessions. Local level inducements and constraints that enhance or impede governmental forest policy adoption and compliance also were identified.

The life history of this insect species and its host range were determined in the laboratory with adult no-choice oviposition and larval development tests. This species has five instars, the first three are sap-feeding miners and the last two are tissue feeding. Total development time was 31.7 days. To examine specificity of this species, 10 plant species in Anacardiaceae were selected based on taxonomic relatedness to S. terebinthifolius, economic importance, and availability. In the laboratory, except for Anacardium occidentale and Cotinus obovatus, all of the tested species were accepted for oviposition with a marked preference for the weed S. terebinthifolius, Schinus molle, Rhus copallinum, Rhus sandwicensis and Pistacia chinensis. Complete development, from egg to adult, was achieved only on S. terebinthifolius, S. molle, R. copallinum, P. chinensis and Metopium toxiferum. In conclusion, E. schinusivora will not be considered for the biological control of S. terebinthifolius in the continental USA. However, the utilisation of this species in other infested areas such as Hawai'i and Australia should be considered.

Investigation of this site included sampling and analysis of water, mineralogical analyses, sequential extraction, in addition to flow and geochemical modeling. The highest dissolved arsenic concentrations correspond to mine tailings (up to 90,000 mu g/L) and the arsenic is present predominately as As(V). The primary source of the arsenic is the dissolution of arsenopyrite. Concentration of antimony reaches 7,500 mu g/L and its primary source is the dissolution of stibnite. Pore water in mine tailings is well-buffered by the dissolution of carbonates (pH values between 6.6 and 7.0) and arsenopyrite grains are surrounded by reaction rims composed of ferric iron minerals. Based on sequential extraction results, most solid phase arsenic is in the reducible fraction (i.e. ferric oxyhydroxides), sulfidic fraction, and residual fraction. Distribution of antimony in the solid phase is similar, but contents are lower. The principal attenuation mechanism for As(V) is adsorption to ferric oxide and hydroxides, but the adsorption seems to be limited by the competition with Sb(V) produced by the oxidation of stibnite for adsorption sites. Water in mine tailings is at equilibrium with gypsum and calcite, but far from equilibrium with any arsenic and antimony minerals. The concentrations of arsenic and antimony in the surrounding aquifer are much lower, with maximum values of 215 and 426 mu g/L, respectively. Arsenic and antimony are transported by ground water flow towards the Blatina Creek, but their loading from ground water to the creek is much lower compared with the input from the mine adits. In the Blatina Creek, arsenic and antimony are attenuated by dilution and by adsorption on ferric iron minerals in stream sediments with resulting respective concentrations of 93 and 45 mu g/L at the site boundary south of mine tailing ponds.

Although it is known that Golden-cheeked Warblers are closely associated with 'encino' oaks (evergreen or holm oak) such as Quercus sapotifolia, Q. eliptica and Q. elongata, which have shiny, narrow, elliptical, or oblong leaves, quantitative habitat targets are useful for effectively incorporating this information into conservation planning and forest management practices. We analysed data on wintering Golden-cheeked Warblers collected during the non-breeding season in Honduras from 1996 to 1998 to identify quantitative targets for habitat conditions for this species. Data on warbler abundance were collected using line transect surveys located in montane pine-oak forests in a stratified-random fashion. Habitat data were collected at five 0.04 ha plots on these same transects and the averaged values used as predictors of Golden-cheeked Warbler abundance. We found that Golden-cheeked Warblers were strongly associated with the basal area of encino oaks and density of 'roble' oaks, such as Q. segoviensis, Q. purulhana and Q. rugosa, which have large, lobed leaves. Density of Golden-cheeked Warblers peaked at approximately 5.6 m2 ha-1 basal area of encino and approximately 7 roble oaks ha-1. These values can be used to identify quantitative habitat targets that can be directly incorporated into forest management practices to ensure that these activities maintain habitat conditions necessary for their use by Golden-cheeked Warblers.

Although mutation in opgB resulted in avirulent Salmonella strain, how this gene contributes to pathogenesis remains unclear. Based on DNA homology, opgB is predicted to be responsible for adding phosphoglycerate residues to osmoregulated periplasmic glucans (OPGs) giving them anionic characteristics. In Escherichia coli, yet another gene, opgC, is also reported to contribute to anionic characteristics of OPGs by adding succinic acid residues. We constructed opgB, opgC, and opgBC double mutants of S. enterica serovar Typhimurium strain SL1344. As predicted opgBC mutant synthesized neutral OPGs that were devoid of any anionic substituents. However, opgB, opgC, and opgBC mutations had no significant impact on mice virulence as well as on competitive organ colonization. In low osmotic conditions, opgB, opgC, and opgBC mutants exhibited delay in growth initiation in the presence of sodium deoxycholate. Anionic substituents of OPGs from Salmonella although appear to be needed to overcome resistance of deoxycholate in hypoosmotic growth media, no evidence was found for their role in mice virulence.

Egg oiling was conducted at Chicago's gull colonies to reduce production and the influx of hatch-year (HY) gulls using Chicago's beaches, with a second, long-term objective of eventually reducing adult gull numbers through attrition. We also investigated swim season water quality trends through the course of this work. From 2007 to 2009, 52, 80, and 81%, of nests at the two primary nest colonies had their eggs rendered inviable by corn oil application. Counts of HY and after hatch-year (AHY) gulls were analyzed during treatment years for 10 beaches. Water quality data were available from the Chicago Park District during our three treatment years and the prior year (baseline) for 19 beaches. HY counts declined at all 10 surveyed beaches from the initial year (52% nests with oiled eggs) to subsequent years with ~80% of nests oiled. Overall, HY gulls numbers on beaches decreased 86% from 2007 to 2009. Decreases in beach usage by AHY gulls were not detected. Compared to pretreatment, the number of beaches with improved water quality test rates increased each year through the course of the study. The frequency of water quality tests showing bacterial exceedances compared to 2006 declined at 18 of 19 beaches by 2009. Egg oiling resulted in fewer HY gulls using Chicago's beaches and was likely a beneficial factor for reduced frequencies of swim advisories and swim bans.

Among these are two live MG vaccines derived from the moderately pathogenic MG "chick F" strain. In the present study, the commercially available F strain derivatives were compared for their ability to elicit seroconversion, persist in vivo, and protect against virulent MG-induced airsacculitis. In addition, a noncommercial laboratory-derived high-passage F strain isolate was included in the study. Commercial (Hy-Line W-36) layers were placed in biological isolation units at 9 wk of age (woa). At 10 woa, birds within each biological isolation unit were treated via eye-drop application with one of the three F strain-derived vaccines at one of four levels (1, 10-1, 10-2, or 10-3). For the commercially available F strain derivatives, 1 equaled the manufacturer's recommended dose. The 1 dose of the noncommercial laboratory-maintained F strain derivative equaled 20 mu l of a 48 hr culture. For wk 1-6 postvaccination (p.v.), sera were collected weekly from each bird, and seroconversion was assessed via serum plate agglutination (SPA). Virulent MG (strain Rlow) challenge occurred via intratracheal inoculation at 7 wk p.v. Necropsies were subsequently performed to assess challenge-associated airsacculitus. For each F strain derivative applied at 1 and 10-1, 100% seroconversion, as measured by SPA, was demonstrated by 6 wk p.v., and rates at the 10-2 dosage were 10% and 90% for the commercial vaccines and 60% for the laboratory-derived strain in this period. Following challenge, airsacculitis was observed in 66.67% of the nontreated controls but not in any 1- or 10-1-treated bird independent of applied F strain derivative.

The newly introduced plants have proved capable of establishing, but because they are rarely monitored for more than four years, it is unknown if they have a high likelihood of persisting and suppressing invaders for the long term. Beyond invaded grasslands, this lack of long-term monitoring is a general problem plaguing efforts to reintroduce a range of taxa into a range of ecosystems. We introduced species from seed and then periodically measured plant abundances for nine years at one site and 15 years at a second site. To our knowledge, our 15-year data are the longest to date from a seeding experiment in invaded, never-cultivated grassland. At one site, three seeded grasses maintained high densities for three or more years, but then all or nearly all individuals died. At the second site, one grass performed similarly, but two other grasses proliferated and at least one greatly suppressed the dominant invader (Cenlaurea maculosa). In one study, our point estimate suggests that the seeded grass Thinopyrum intermedium reduced C. maculosa biomass by 93% 15 years after seeding. In some cases, data from three and fewer years after seeding falsely suggested that seeded species were capable of persisting within the invaded grassland. In other cases, data from as late as nine years after seeding falsely suggested seeded populations would not become large enough to suppress the invader. These results show that seeded species sometimes persist and suppress invaders for long periods, but short-term data cannot predict if, when, or where this will occur. Because short-term data are not predictive of long-term seeded species performances, additional long-term data are needed to identify effective practices, traits, and species for revegetating invaded grasslands.

AN - 1032892774; 16966619 AB - Insect disturbance is often thought to increase fire risk through enhanced fuel loadings, particularly in coniferous forest ecosystems. Yet insect disturbances also affect successional pathways and landscape structure that interact with fire disturbances (and vice-versa) over longer time scales. We applied a landscape succession and disturbance model (LANDIS-II) to evaluate the relative strength of interactions between spruce budworm (Choristoneura fumiferana) outbreaks and fire disturbances in the Boundary Waters Canoe Area (BWCA) in northern Minnesota (USA). Disturbance interactions were evaluated for two different scenarios: presettlement forests and fire regimes vs. contemporary forests and fire regimes. Forest composition under the contemporary scenario trended toward mixtures of deciduous species (primarily Betula papyrifera and Populus spp.) and shade-tolerant conifers (Picea mariana, Abies balsamea, Thuja occidentalis), with disturbances dominated by a combination of budworm defoliation and high-severity fires. The presettlement scenario retained comparatively more "big pines" (i.e., Pinus strobus, P. resinosa) and tamarack (L. laricina), and experienced less budworm disturbance and a comparatively less-severe fire regime. Spruce budworm disturbance decreased area burned and fire severity under both scenarios when averaged across the entire 300-year simulations. Contrary to past research, area burned and fire severity during outbreak decades were each similar to that observed in non-outbreak decades. Our analyses suggest budworm disturbances within forests of the BWCA have a comparatively weak effect on long-term forest composition due to a combination of characteristics. These include strict host specificity, fine-scaled patchiness created by defoliation damage, and advance regeneration of its primary host, balsam fir (A. balsamea) that allows its host to persist despite repeated disturbances. Understanding the nature of the three-way interaction between budworm, fire, and composition has important ramifications for both fire mitigation strategies and ecosystem restoration initiatives. We conclude that budworm disturbance can partially mitigate long-term future fire risk by periodically reducing live ladder fuel within the mixed forest types of the BWCA but will do little to reverse the compositional trends caused in part by reduced fire rotations.

Our objective in this research was to identify ASR proteins expressed early during infection for the development of immunodiagnostic assays. We have identified and partially characterized a small gene family encoding extracellular proteins in the P. pachyrhizi urediniospore wall, termed PHEPs (for Phakopsora extracellular protein). Two highly expressed protein family members, PHEP 107 and PHEP 369, were selected as ideal immunodiagnostic targets for antibody development, after we detected PHEPs in plants as early as 3 days postinfection (dpi). Monoclonal antibodies (MAbs; 2E8E5-1 and 3G6H7-3) generated against recombinant PHEP 369 were tested for sensitivity against the recombinant protein and extracts from ASR-infected plants and for specificity against a set of common soybean pathogens. These antibodies should prove applicable in immunodiagnostic assays to detect infected soybeans and to identify ASR spores from sentinel surveillance plots.

All bison were challenged intraconjunctivally in midgestation with 107 CFU of B. abortus strain 2308 (S2308). Bison were necropsied and sampled within 72 h of abortion or delivery of a live calf. Compared to nonvaccinated bison, bison in the booster RB51 treatment had a reduced (P 0.05) from the control group in the incidence of abortion or recovery of S2308 from uterine, mammary, fetal, or maternal tissues at necropsy. Compared to nonvaccinated animals, all RB51 vaccination groups had reduced (P < 0.05) mean colonization or incidence of infection in at least 2 of 4 target tissues, with the booster RB51 group having reduced (P < 0.05) colonization and incidence of infection in all target tissues. Our data suggest that booster vaccination of bison with RB51 enhances protective immunity against Brucella challenge compared to single vaccination with RB51 by hand or by pneumatic dart. Our study also suggests that an initial vaccination of calves followed by booster vaccination as yearlings should be an effective strategy for brucellosis control in bison.

Nearly 20 yr later, new biotypes appeared that were capable of overcoming most sources of resistance and became a renewed threat to wheat, Triticum aestivum L., production. Cyclical (CP) and obligate (OP) parthenogenesis enables aphids to both adapt to changing environments and exploit host resources. We documented these forms of reproduction for Russian wheat aphid in wheat and wild grasses in the Central Great Plains and Rocky Mountain regions during falls 2004-2009. Colonies from sample sites also were held under unheated greenhouse conditions and observed for the presence of sexual morphs and eggs through the winter. Russian wheat aphid populations were mainly OP and attempted to overwinter as adults, regardless of region sampled. A few populations contained oviparae but no males (gynocyclic) and were not specific to any particular region. Observation of the Russian wheat aphid colonies under greenhouse conditions failed to produce males or eggs. In spring 2007, CP was confirmed in a small population of Russian wheat aphid that eclosed from eggs (fundatricies) on wild grasses and wheat near Dove Creek, CO, in the Colorado Plateau region where other aphid species undergo CP. Lineages from ninety-three fundatricies were screened against 16 resistant and susceptible cereal entries to determine their biotypic classification. A high degree of biotypic diversity (41.4%) was detected in this population. Although CP was a rare in Russian wheat aphid populations, genetic recombination during the sexual cycle creates new biotypes and can have significant effects on population genetics.

A consequence of this activity is the mixing of native and introduced species and the formation of novel biotic communities. We review the ecological consequences of the mixing of native and introduced species in the Caribbean Islands especially in Puerto Rico and the US Virgin Islands. Here we found documented examples indicating that novel communities of native and naturalized organisms are ubiquitous. The coexistence of species originating from different biogeographical regions raises research questions that demand attention for their ecological and conservation importance. For example: Is animal abundance in novel communities a measure of habitat quality? To what degree are populations in novel communities self-sustaining? What are the consequences of species eradication? How does an introduced animal's trophic position affect its effects on novel and native communities? We suggest that novel communities that emerge in the Caribbean after deforestation and land abandonment could be harbingers of how the biota might respond elsewhere to rapidly changing environmental conditions, including global and climate change.

A study was conducted to assay the effect of selected diets on the survival of adult D. catalinae. Treatments of water (as a control), 10% honey, honeydew, and whiteflies [Bemisia tabaci (Gennadius)] were provided to the beetles in laboratory assays. Newly emerged, unfed adult insects were used at the start of a survival experiment with trials lasting 50 d. Another survival experiment used mixed-aged adults from a greenhouse colony, and the trials lasted 21 d. Survival was poor on a diet of solely water; approximately 1% survived beyond a week at 26 degree C Survival using the newly emerged insects was similar between those fed honeydew and honey diets, but those on the whitefly diet had the greatest survival ( approximately 60% on day 50). However, in the experiment with mixed-aged beetles, adults on honey, and whitefly diets performed the same over a 21-d experiment. Excluding those on the water diet, survival of beetles on the various diets ranged from approximately 50-80% after 21 d. In an open choice assay across 7 h, D. catalinae adults were found on the whitefly diet in a much greater incidence than on the other diets, and the number of beetles found on the whitefly diet increased over time. The data supports that when D. catalinae are employed in greenhouses or fields for whitefly management, during low prey populations, honeydew from the whitefly can help sustain the population of this predator. Moreover, a supplemental food such as a honey solution can help sustain the population of D. catalinae when the prey is decreased to low numbers. These results may help in the development of strategies to enhance the utility of predators for the management of whiteflies.

Irradiation dose did not affect the parasitoid's offspring sex ratio (53-62% females), percentage of unemerged adults (12-34%), number of progeny produced per female (1.4-1.8), and parasitism (19-24%). Host irradiation dose had no significant effect on the forewing length of female P. humilis and its parasitism on olive fruit fly, Bactrocera oleae (Rossi) and offspring sex ratio, but dissection of 1-wk-old female parasitoids reared from hosts irradiated with 70 Gy had a significantly lower number of mature eggs than females from nonirradiated hosts. Longevity of P. humilis adults decreased with increased temperature from 15 to 35 degree C, regardless of food provisions, gender, and host irradiation dose. Females survived 37-49 d at 15 degree C with water and food, and only 1-2 d at 35 degree C without food, whereas males lived shorter than females at all temperatures and food combinations tested. Adult P. humilis reared from fertile C. capitata and aspirated for dispensing in cups lived significantly longer after shipment than those specimens chilled and dispensed by weight. At 21 and 32 degree C, 50% of parasitoids departed release cages after 180 and 30 min, respectively, but none departed at 12 degree C. Thirteen shipments of P. humilis (2,980-21,922 parasitoids per shipment) were received between September and December 2009, and seven shipments (7,502-22,560 parasitoids per shipment) were received between October and December 2010 from San Miguel Petapa, Guatemala. Daily number of olive fruit fly adult and percentage female trap captures ranged <1-19 and 8-58% in 2009, and <1-11 and 0-42% in 2010, respectively. The number of parasitoids released ranged 848-12,257 in 2009 and 3,675-11,154 in 2010. Percentage parasitism of olive fruit fly third instars at all locations ranged 0-9% in 2009 and 0-36% in 2010.

Moench, respectively) as host plants. Because these are new host plant records for this polyphagous species, we investigated foxglove aphid development and reproduction on pale and black swallow-wort relative to a known crop host, potato (Solanum tuberosum L.), at a 25:20 degree C thermophase and a photoperiod of 16:8 (L:D) h. Almost no such data have been previously reported for a noneconomic host plant. Larval development and survival, as well as adult reproductive development and fecundity, were similar between the two swallow-wort species and potato. Adult aphids lived significantly longer on pale swallow-wort than the other two host plants, but this extended longevity encompassed the postreproductive stage. Foxglove aphid population parameters were therefore similar among the three plant species as well as most previous reports on crop plants. Pale and black swallow-wort appear to be suitable secondary hosts for foxglove aphid; other factors possibly limit aphid abundance on these two plant species in the field.

F. bispinosa was the predominant thrips observed on both flowers but colonized D. carota to a greater extent and earlier in the season than A. majus. Despite differences in the abundance of F. bispinosa on the two plants, neither Orius species showed host plant affinities. Population profiles for the thrips and Orius spp. followed a density dependent response of prey to predator with a large initial prey population followed by a rapid decline as the predator populations increased. The temporal increases in Orius spp. populations during the flowering season suggest that they were based on reproductive activity. As observed in a previous study, O. insidiosus had a larger population than O. pumilio and also had a predominantly male population on the flowers. By examining carcasses of the prey, there appeared to be no sexual preference of the thrips as prey by the Orius spp. as the prey pattern followed the demographics of the thrips sex ratio. Few immatures of either thrips or Orius spp. were observed on D. carota or A. majus, which suggests that oviposition and nymphal development occurred elsewhere. Based on these findings, D. carota and A. majus could serve as a banker plant system for Orius spp. JF - Environmental Entomology AU - Shirk, Paul D AU - Shapiro, Jeffrey P AU - Reitz, Stuart R AU - Thomas, Jean MG AU - Koenig, Rosalie L AU - Hay-Roe, Mirian M AU - Buss, Lyle J AD - Center for Medical, Agricultural, and Veterinary Entomology, Agricultural Research Service, U.S. Department of Agriculture, Gainesville, FL 32608., paul.shirk@ars.usda.gov Y1 - 2012/06// PY - 2012 DA - Jun 2012 SP - 487 EP - 496 PB - Entomological Society of America, 9301 Annapolis Rd.

Research has demonstrated that codling moth neonate first instar larvae are attracted to a pear-derived kairomone, ethyl (2E,4Z) -2,4-decadienoate, the pear ester (PE). Reported here are the behavioral activities of neonate codling moth larvae to microencapsulated pear ester (MEC-PE) applied in aqueous solutions to both filter paper and apple leaf surfaces that were evaluated over a period of up to 20 d of aging. In dual-choice tests the MEC-PE treatment elicited attraction to and longer time spent on treated zones of filter papers relative to water-treated control zones for up to 14 d of aging. A higher concentration of MEC-PE caused no preferential response to the treated zone for the first 5 d of aging followed by significant responses through day 20 of aging, suggesting sensory adaptation as an initial concentration factor. Estimated emission levels of PE from treated filter papers were experimentally calculated for the observed behavioral thresholds evident over the aging period. When applied to apple leaves, MEC-PE changed neonate walking behavior by eliciting more frequent and longer time periods of arrestment and affected their ability to find the leaf base and stem or petiole. Effects of MEC-PE on extended walking time and arrestment by codling moth larvae would increase temporal and spatial exposure of neonates while on leaves; thereby potentially disrupting fruit or nut finding and enhancing mortality by increasing the exposure to insecticides, predation, and abiotic factors.

A variety of laboratory- and field-based experiments were conducted in pursuit of improved monitoring strategies and to develop a trap tree strategy for ambrosia beetles. Traps baited with bolts prepared from Magnolia virginiana L. injected with ethanol caught five times more X. germanus than ethanol-baited traps. Basal stem injections of ethanol into M. virginiana induced more ambrosia beetle attacks than irrigating or baiting with ethanol, and no attacks occurred on water-injected trees. A positive correlation was also detected between concentration of injected ethanol and cumulative attacks. Solid phase microextraction-gas chromatography-mass spectrometry characterized bark emissions from ethanol- and water-injected M. virginiana at 1, 2, 10, and 16 d after treatment. Ethanol emission from injected trees steadily declined from 1 to 16 d after treatment, but was not emitted from water-injected trees. A variety of monoterpenes were also emitted in trace amounts from the ethanol- and water-injected trees. Antennal responses of X. germanus via gas chromatography-electroantennographic detection to volatiles from ethanol-injected M. virginiana occurred for ethanol, but not the various monoterpenes. X. germanus and other ambrosia beetles were also equally attracted to traps baited with ethanol alone compared with a synthetic mixture of ethanol plus various monoterpenes formulated to mimic ethanol-injected M. virginiana. Injecting concentrated solutions of ethanol into trees may be useful for establishing odor-based trap trees, which could aid with monitoring programs and/ or potentially deflect ambrosia beetles away from valuable nursery stock.

Ants occupy virtually every ecological niche and have evolved mechanisms to not just cope with, but also manipulate soil organisms. The metapleural gland, specific to ants was thought to be the major source of semiochemical antimicrobial compounds targeting general or specific deleterious microbes. The extremely diverse variety of semiochemicals and their sources with antimicrobial activity or potential activity is highlighted. The leaf-cutting ants and fire ant provide the most researched species, in part because they cause significant economic damage. The leaf-cutting ant is particularly interesting because researchers have uncovered unexpected interactions between leaf-cutting ant fungal farm, parasitic fungi, bacteria, yeasts, and ant defensive semiochemicals. These complex relationships highlight the multidimensional aspects of ants and the soil environment in which they live.

The global citrus industry is in urgent need of effective chemical treatments for HLB control because of its rapid spreading worldwide. Due to the fastidious nature of the pathogens, and the poor permissibility of citrus leaf surfaces, effective screening of chemicals for the HLB control can be challenging. In this study, we developed a graft-based chemotherapy method to rapidly screen potential HLB-controlling chemical compounds. In addition, we improved transmission efficiency by using the best HLB-affected scion-rootstock combination, and demonstrated the HLB bacterial titer was the critical factor in transmission. The HLB-affected lemon scions had a high titer of HLB bacterium, survival rate (83.3%), and pathogen transmission rate (59.9%). Trifoliate, a widely used commercial rootstock, had the highest survival rate (>70.0%) compared with grapefruit (52.6%) and sour orange (50.4%). Using this method, we confirmed a mixture of penicillin and streptomycin was the most effective compounds in eliminating the HLB bacterium from the HLB-affected scions, and in successfully rescuing severely HLB-affected citrus germplasms. These findings are useful not only for chemical treatments but also for graft-based transmission studies in HLB and other Liberibacter diseases.

The effects of varying amounts of unconsolidated surface materials on runoff nutrient losses are not well understood. The objectives of this study were to (1) compare runoff nutrient losses from feedlot surfaces containing varying amounts of unconsolidated surface materials, (2) determine if differences in runoff nutrient losses exist among rainfall simulation runs, (3) relate runoff nutrient losses to selected feedlot soil characteristics, and (4) identify the effects of varying runoff rate on nutrient loss rates from feedlot surfaces. This study was conducted on 0.75 m wide by 2 m long (2.47 ft wide by 6.58 ft long) plots containing 0, 6.7, 13.5, or 26.9 kg m super(-2) (0, 1.37, 2.77, or 5.51 lb ft super(-2)) of unconsolidated surface materials. Simulated rainfall was applied during three 30-minute events that were separated by 24-hour intervals. Inflow was added at the top of all plots during selected tests to examine the effects of varying flow rate on nutrient loss rates. No significant differences in the measured water quality parameters were found among the surfaces containing varying amounts of unconsolidated surface materials. Measurements of dissolved phosphorus, particulate phosphorus, total phosphorus, ammonium nitrogen, chloride, total dissolved solids, electrical conductivity, and erosion consistently decreased during the three rainfall simulation runs. Runoff losses of ammonium nitrogen (NH sub(4)-N), total nitrogen, and nitrate nitrogen were all correlated to easily obtained soil EC measurements. All measured water quality parameters were significantly influenced by runoff rate. Thus, runoff rate, and not the amount of unconsolidated surface materials on the feedlot surface, significantly influenced nutrient losses in runoff.

Landscape-scale assessment of this vital information has resorted to the use of remote sensing technology. The cellulose absorption index (CAI) technique has outperformed other indices for discriminating bare soil and crop residue in the Midwest, but has not been tested in the Pacific Northwest and the Central and Northern Great Plains regions of the United States. The objective of this study is to assess the performance of CAI in these regions. Malting barley (Hordeum vulgare L.), spring wheat (Triticum aestivum L.), durum (Triticum turgidum L.), field pea (Pisum sativum L.), and fallow following spring wheat and proso millet (Panicum miliaceum L.) were used in the assessment. Using a portable ground-based spectroradiometer, as well as transect line and photo-grid methods, crop residue cover was measured after the 2009 harvest season. Samples were collected for laboratory analyses. Linear regression analysis showed CAI explained 41% to 55% of the variation in the residue cover. Field pea and fallow residue cover had better correlation with CAI than did small grain crop residues. Field and laboratory measurement of CAI showed that varying pea residue cover responded significantly different than other crop residues. The performance of CAI was affected by the type of crop rather than by location and soil type in the regions. Among other measured parameters, percentage crop residue cover, hemicellulose, and residue amount were most correlated with CAI. Results document that CAI can quickly and effectively estimate percentage of residue cover in the regions.

These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and (3) large-scale biogeochemistry. This study characterized the surface water sources of nitrogen (N) (total, nitrate [NO super(-) sub(3)], ammonium [NH super(+) sub(4)], and dissolved organic N) and sediment active within 40 subbasins of the Calapooia River Basin in western Oregon in monthly samples over three cropping years. The subbasins included both independent and nested drainages, with wide ranges in tree cover, agricultural practices, slopes, and soils. Sediment and N form concentrations were tested against weather and agricultural practice variables. Subbasin land use ranged from 96% forest to 100% agriculture. Average slopes varied from 1.3% to 18.9%, and surface water quality ranged from 0.5 to 43 mg L super(-1) (ppm) total N maxima and 29 to 249 mg L super(-1)suspended sediment maxima. Total N during the winter was positively related to percentage landcover of seven common agricultural crops (nongrass seed summer annuals, established seed crops of perennial ryegrass [Lolium perenne L.], tall fescue [Schedonorus phoenix {Scop.} Holub], orchardgrass [Dactylis glomerata L.], clover [Trifolium spp.], and newly planted stands of perennial ryegrass and clover) and negatively related to cover by trees and one seed crop, Italian (annual) ryegrass (Lolium multiflorum). Results for NO super(-) sub(3) and total N were highly similar. Sediment concentrations were most strongly related to rainfall totals during periods of 4 and 14 days prior to sampling, with smaller effects of soil disturbance. Fourier analysis of total N over time identified four prominent groups of subbasins: those with (1) low, (2) medium, and (3) high impacts of N (up to 2,8, and 21 mg super(-1) respectively) and a strong cyclical signal peaking in December and (4) those with very high impact of N (up to 43 mg L super(-1)) and a weak time series signal. Preponderance of N in streams draining agriculturally dominated subbasins was in the form of the NO super(-) sub(3) ion, implying mineralization of N that had been incorporated within plant tissue following its initial application in the spring as urea-based fertilizer. Since mineralization is driven by seasonal rainfall and temperature patterns, changes in agronomic practices designed to reduce prompt runoff of fertilizer are unlikely to achieve to more than similar to 24% reduction in N export to streams.

Model simulations from 1977 through 2006 were used to evaluate six manure nutrient management scenarios that reflect realistic strategies that could be employed to reduce nutrient and sediment loadings in the LRW. Due to the presence of several dairies and a relatively large number of cows, special attention within this watershed is necessary to determine beneficial adjustments that can be made to protect water quality. The nutrient management scenarios analyzed reduced total nitrogen (N) and total phosphorus (P) loading in nearly all of the subbasins. Total N and total P loading was also reduced at the watershed scale; sediment load reduction was minor due to effective management measures already existing within the LRW. The percentage change in total N and total P loadings varied from an increase of 3% to a decrease of 11% and an increase of 5% to a decrease of 12%, respectively. The percentage change in sediment loadings varied from an increase of 22% to a decrease of 12% per subbasin. Model simulations conducted over a 30-year period for six manure management scenarios indicated that both total N and total P can be significantly reduced by employing additional nutrient strategies. This is the case whether the nutrients are removed from the immediate vicinity of the dairy or are transported outside of the watershed.

Analysis of this Gac/Rsm signal transduction pathway in phytotoxin-producing pathovars of Pseudmonas syringae is incomplete, particularly with regard to rsmA. Our approach in studying it was to overexpress rsmA in P. syringae strains through introduction of pSK61, a plasmid constitutively expressing this gene. Disease and colonization of plant leaf tissue were consistently diminished in all P. syringae strains tested (pv. phaseolicola NPS3121, pv. syringae B728a, and BR2R) when harboring pSK61 relative to these isolates harboring the empty vector pME6031. Phaseolotoxin, syringomycin, and tabtoxin were not produced in any of these strains when transformed with pSK61. Production of protease and pyoverdin as well as swarming were also diminished in all of these strains when harboring pSK61. In contrast, alginate production, biofilm formation, and the hypersensitive response were diminished in some but not all of these isolates under the same growth conditions.

'Candidatus Liberibacter asiaticus' is the prevalent species of three HLB-associated Liberibacter spp., which is vectored by the psyllid Diaphorina citri. The vector and the bacteria have host plants outside the genus Citrus, and these plants have the potential to affect disease epidemiology within citrus groves. Murraya paniculata could be especially problematic because it is a popular ornamental plant and a host of both psyllid and bacteria. We conducted a year-long survey of eight urban plantings of M. paniculata in east-central Florida to characterize 'Ca. L. asiaticus' infection rates in plants and associated psyllids. Using sensitive quantitative polymerase chain reaction (qPCR) primers targeting two prophage genes of 'Ca. L. asiaticus', we found infection to be extremely low: less than 1% of psyllids and 1.8% of plants. With qPCR primers targeting 'Ca. L. asiaticus' 16S rDNA, none of the plants and only one psyllid were 'Ca. L. asiaticus'-positive. Therefore, the titer of 'Ca. L. asiaticus' is low in M. paniculata and associated psyllids. These results suggest that urban plantings of M. paniculata may serve as a minor source of 'Ca. L. asiaticus' inoculum.

Five diverse land management practices were studied for their impacts on Fusarium wilt (Fusarium oxysporum f. sp. lycopersici), galling of roots by Meloidogyne spp. and marketable yield of tomato (Solarium lycopersicum) and to identify associations between the severity of pest damage and the corresponding soil microbial community structure. The incidence of Fusarium wilt was >14% when tomato was cultivated following 3 to 4 years of an undisturbed weed fallow or continuous tillage disk fallow rotation and was >4% after 3 to 4 years of bahiagrass (Paspalum notatum) rotation or organic production practices that included soil amendments and cover crops. The incidence of Fusarium wilt under conventional tomato production with soil fumigation varied from 2% in 2003 to 15% in 2004. Repeated tomato cultivation increased Fusarium wilt by 20% or more except when tomato was grown using organic practices, where disease remained less than 3%. The percent of tomato roots with galls from Meloidogyne spp. ranged from 18 to 82% in soil previously subjected to a weed fallow rotation and 7 to 15% in soil managed previously as a bahiagrass pasture. Repeated tomato cultivation increased the severity of root galling in plots previously subjected to a conventional or disk fallow rotation but not in plots managed using organic practices, where the percentage of tomato roots with galls remained below 1%. Marketable yield of tomato exceeded 35 Mg ha super(-1) following all land management strategies except the strip-tillage/bahiagrass program. Marketable yield declined by 11, 14, and 19% when tomato was grown in consecutive years following a bahiagrass, weed fallow, and disk rotation. The composition of fungal internal transcribed spacer 1 (ITS1) and bacterial 16S rDNA amplicons isolated from soil fungal and bacterial communities corresponded with observed differences in the incidence of Fusarium wilt and severity of root galling from Meloidogyne spp. and provided evidence of an association between the effect of land management practices on soil microbial community structure, severity of root galling from Meloidogyne spp., and the incidence of Fusarium wilt.

These properties have recently been exploited therapeutically to treat human diseases. The biocomplexity of the intestinal lumen suggests that interactions between the parasite and the intestinal microbiota would also influence inflammation. In this study, we characterized the microbiota in the porcine proximal colon in response to Trichuris suis (whipworm) infection using 16S rRNA gene-based and whole-genome shotgun (WGS) sequencing. A 21-day T. suis infection in four pigs induced a significant change in the composition of the proximal colon microbiota compared to that of three parasite-naive pigs. Among the 15 phyla identified, the abundances of Proteobacteria and Deferribacteres were changed in infected pigs. The abundances of approximately 13% of genera were significantly altered by infection. Changes in relative abundances of Succinivibrio and Mucispirillum, for example, may relate to alterations in carbohydrate metabolism and niche disruptions in mucosal interfaces induced by parasitic infection, respectively. Of note, infection by T. suis led to a significant shift in the metabolic potential of the proximal colon microbiota, where 26% of all metabolic pathways identified were affected. Besides carbohydrate metabolism, lysine biosynthesis was repressed as well. A metabolomic analysis of volatile organic compounds (VOCs) in the luminal contents showed a relative absence in infected pigs of cofactors for carbohydrate and lysine biosynthesis, as well as an accumulation of oleic acid, suggesting altered fatty acid absorption contributing to local inflammation. Our findings should facilitate development of strategies for parasitic control in pigs and humans.

To date, progress determining mechanisms of host-plant susceptibility, tolerance, or resistance has been slow, due in large part to the long generation time and limited available genetic resources for grape, almond, and other known hosts of X. fastidiosa. To overcome many of these limitations, Arabidopsis thaliana has been evaluated as a host for X. fastidiosa. A pin-prick inoculation method has been developed to infect Arabidopsis with X. fastidiosa. Following infection, X. fastidiosa multiplies and can be detected by microscopy, polymerase chain reaction, and isolation. The ecotypes Van-0, LL-0, and Tsu-1 all allow more growth of strain X. fastidiosa Temecula than the reference ecotype Col-0. Affymetrix ATH1 micro-array analysis of inoculated vs. noninoculated Tsu-1 reveals gene expression changes that differ greatly from changes seen after infection with apoplast-colonizing bacteria such as Psuedomonas syringae pvs. tomato or syringae. Many genes responsive to oxidative stress are differentially regulated, while classic pathogenesis-related genes are not induced by X. fastidiosa infection.

Previously, we developed an inhibitor-tolerant Saccharomyces cerevisiae strain NRRL Y-50049 that is able to in situ detoxify common aldehyde inhibitors such as 2-furaldehyde (furfural) and 5-(hydroxymethyl)-2-furaldehyde (HMF). In this study, we genetically engineered Y-50049 to enable and enhance its xylose utilization capability. A codon-optimized xylose isomerase gene for yeast (YXI) was synthesized and introduced into a defined chromosomal locus of Y-50049. Two newly identified xylose transport related genes XUT4 and XUT6, and previously reported xylulokinase gene (XKS1), and xylitol dehydrogenase gene (XYL2) from Scheffersomyces stipitis were also engineered into the yeast resulting in strain NRRL Y-50463. The engineered strain was able to grow on xylose as sole carbon source and a minimum ethanol production of 38.6 g l super(-1) was obtained in an anaerobic fermentation on mixed sugars of glucose and xylose in the presence of furfural and HMF.

Oil extracted from DDGS was converted into distillers' grains methyl (DGME) and ethyl (DGEE) esters. Pretreatment using sulfuric acid was effective at lowering the acid value of the crude oil from 27.15 to less than 0.30 mg KOH g super(-1), thus rendering it amenable to homogenous, base-catalyzed transesterification. Measurement of fuel properties and comparison to refined corn oil methyl (RCME) and ethyl (RCEE) esters revealed that the cold flow properties and oxidative stability of DGME and DGEE were deficient relative to RCME and RCEE. In the absence of antioxidants, DGME and DGEE did not meet the oxidative stability specifications of ASTM D6751 and EN 14214. The cetane number of DGEE was below the minimum limit specified in EN 14214. DGEE exhibited more favorable cold flow properties, iodine value, and energy content than DGME. Evaluation of blends (B5 and B20) in petroleum diesel fuel revealed that antioxidants and cetane enhancers would be required to meet the specifications of the US and European diesel fuel standards. Other fuel properties of the petrodiesel blends were largely neutral with respect to alkyl ester type and conformed to the limits specified in the respective standards.

Cell wall polysaccharide hydrolysis was compared for a dilute sulfuric acid pretreatment at 121 degree C followed with cellulase hydrolysis for 72 h conversion assay (CONV) with in vitro rumen microflora incubation for 72 h (RUMEN) for a set of maize (Zea mays L.) stover samples with a wide range in cell wall composition. Residual polysaccharides from the assays were analyzed for sugar components and extent of hydrolysis calculated. Cell wall polysaccharide hydrolysis was different for all sugar components between the CONV and RUMEN assays. The CONV assay hydrolyzed xylose-, arabinose-, galactose-, and uronic acid-containing polysaccharides to a greater degree than did the RUMEN assay, whereas the RUMEN assay was more effective at hydrolyzing glucose- and mannose-containing polysaccharides. Greater hydrolysis of hemicelluloses and pectins by CONV can be attributed to the acid hydrolysis mechanism of the CONV assay for noncellulosic polysaccharides, whereas the RUMEN assay was dependent on enzymatic hydrolysis. While CONV and RUMEN hydrolysis were correlated for most polysaccharide components, the greatest correlation was only r=0.70 for glucose-containing polysaccharides. Linear correlations and multiple regressions indicated that polysaccharide hydrolysis by the RUMEN assay was negatively associated with lignin concentration and ferulate ether cross linking as expected. Corresponding correlations and regressions for CONV were less consistent and occasionally positive. Use of rumen microbial hydrolysis to characterize biomass performance in a conversion process may have some limited usefulness for genetic evaluations, but such assays would be unreliable for biomass pricing.

A candidate feedstock is assigned a FSRL level from 1 through 9, indicating an increasing level of maturity towards commercialization. The FSRL level also communicates the state of development of a feedstock concurrent with its readiness for use with a conversion process. There are four components to the FSRL (production, market, policy, and linkage to conversion process), each with one to four tollgate descriptions per readiness level. The FSRL tool was structured to complement the Fuel Readiness Level (FRL) tool in use by the aviation industry as an internationally recognized communication best practice. Similarly, the FSRL can be used to identify gaps in any feedstock supply chain designed for any biofuel or conversion process that provides a market for feedstocks. This integrated feedstock and conversion technology approach can facilitate a coordinated allocation of resources to effectively plan for and develop a viable aviation biofuels industry.

However, implementation of these burn regimes often overlooks responses of other taxa, particularly arthropods. In this study, the timing and frequency of burns were examined on one of the most diverse and abundant groups of herbivorous insects, Auchenorrhyncha. These insects are ideal candidates in understanding the effects of fire on prairie arthropods because they are among the most numerous invertebrate herbivores in the prairie and they have ecological characteristics that confer a wide range of responses to prescribed burning. A total of 19 Illinois hill prairies were sampled along the Mississippi and Sangamon Rivers in the summer of 2006 using a modified leaf-blower vacuum. These sites exhibited a wide range of burn management, from unburned to recently burned, and having been burned multiple times. Species richness, Auchenorrhyncha Quality Index (with and without abundance data) and the mean coefficient of conservatism (with and without abundance data) were calculated for each site. Results suggest that unburned sites supported the greatest number of species and had higher Auchenorrhyncha Quality Index and mean coefficient of conservatism values than sites undergoing burn management. In order for land managers to maintain the prairie Auchenorrhyncha community and conserve vascular plants, this study recommends infrequent rotational burning with a minimum of 3-5 years; although additional studies are needed to determine the appropriate number of years between each burn.

This study sought to quantify the effects of an integrated crop-livestock system on near-surface soil properties in central North Dakota, USA. Soil bulk density, electrical conductivity, soil pH, extractable N and P, potentially mineralizable N, soil organic carbon (SOC) and total nitrogen (TN) were measured 3, 6 and 9 years after treatment establishment to evaluate the effects of residue management (Grazed, Hayed and Control), the frequency of hoof traffic (High traffic, Low traffic and No traffic), season (Fall and Spring) and production system (integrated annual cropping versus perennial grass) on near-surface soil quality. Values for soil properties were incorporated into a soil quality index (SQI) using the Soil Management Assessment Framework to assess overall treatment effects on soil condition. Residue management and frequency of hoof traffic did not affect near-surface soil properties throughout the evaluation period. Aggregated SQI values did not differ between production systems 9 years after treatment establishment (integrated annual cropping=0.91, perennial grass=0.93; P=0.57), implying a near-identical capacity of each system to perform critical soil functions. Results from the study suggest that with careful management, agricultural producers can convert perennial grass pastures to winter-grazed annual cropping systems without adversely affecting near-surface soil quality. However, caution should be exercised in applying results to other regions or management systems. The consistent freeze/thaw and wet/dry cycles typical of the northern Great Plains, coupled with the use of no-till management, modest fertilizer application rates and winter grazing likely played an important role in the outcome of the results.

(Diptera: Muscidae), is one of the most serious pests to livestock. It feeds mainly on cattle and causes significant economic losses in the cattle industry. Standard stable fly control involving insecticides and sanitation is usually costly and often has limited effectiveness. As we continue to evaluate and develop safer fly control strategies, the present study reports on the effectiveness of catnip (Nepeta cataria L.) oil and its constituent compounds, nepetalactones, as stable fly repellents. The essential oil of catnip reduced the feeding of stable flies by >96% in an in vitro bioassay system, compared with other sesquiterpene-rich plant oils (e.g. amyris and sandalwood). Catnip oil demonstrated strong repellency against stable flies relative to other chemicals for repelling biting insects, including isolongifolenone, 2-methylpiperidinyl-3-cyclohexen-1-ca rboxamide and (1S,2'S)-2-methylpiperidinyl-3-cycloh exen-1-carboxamide. The repellency against stable flies of the most commonly used mosquito repellent, DEET, was relatively low. In field trials, two formulations of catnip oil provided >95% protection and were effective for up to 6 h when tested on cattle. Catnip oil also acted as a strong oviposition repellent and reduced gravid stable fly oviposition by 98%.

Rising atmospheric [CO2] is predicted to affect C3 and C4 weed interference with crop species differently, with C3 weeds benefiting more from elevated [CO2] (eCO2) than C4 species. Our aim was to quantify impacts of eCO2 on C3 and C4 weeds at three levels of biological organisation: individual, population and community. We conducted a field study in 2007 and 2008 within the SoyFACE experiment in Champaign, Illinois, USA, in which Amaranthus rudis (C4) and Chenopodium album (C3) were grown with soyabean. This is a Free Air CO2 Enrichment (FACE) experiment. Elevated [CO2] influenced weeds at all levels of biological organisation. However, community-level impacts were largest. Interference by A. rudis and C. album with soyabean was 37% and 11% lower, respectively, in eCO2. In residual weed communities under ambient [CO2] (aCO2), C3 and C4 species were equally likely to dominate the community, whereas in eCO2, there was a 90% chance of community dominance by C3 species. Future investigations of weed ecology and global change under FACE conditions may improve their inference space by including sources of environmental stress such as ozone, heat and drought.

Compared with non-stress-adapted yeast cells, stress-adapted cells exhibited better control of apple fruit infections by Penicillium expansum and Botrytis cinerea and had initially higher growth rates in apple wounds. Suppression subtractive hybridization analysis was used to identify genes expressed in yeast in response to sublethal oxidative stress. Transcript levels were confirmed using semiquantitative reverse transcription-PCR. Seven antioxidant genes were upregulated. The elevated expression of these genes was associated with less accumulation of reactive oxygen species and a lower level of protein and lipid oxidation under subsequent stresses. These data support the premise that induction of abiotic stress tolerance in biocontrol yeast can improve biocontrol efficacy by upregulation of genes involved in the amelioration of oxidative stress.

AN - 1017622238; 22449544 AB - Piperidine alkaloids are acutely toxic to adult livestock species and produce musculoskeletal deformities in neonatal animals. These teratogenic effects include multiple congenital contracture (MCC) deformities and cleft palate in cattle, pigs, sheep, and goats. Poisonous plants containing teratogenic piperidine alkaloids include poison hemlock (Conium maculatum), lupine (Lupinus spp.), and tobacco (Nicotiana tabacum) [including wild tree tobacco (Nicotiana glauca)]. There is abundant epidemiological evidence in humans that link maternal tobacco use with a high incidence of oral clefting in newborns; this association may be partly attributable to the presence of piperidine alkaloids in tobacco products. In this review, we summarize the evidence for piperidine alkaloids that act as teratogens in livestock, piperidine alkaloid structure-activity relationships and their potential implications for human health.

Remote sensing techniques, including image interpretation, have shown promise for collecting plant community composition and ground cover data efficiently. More work needs to be done, however, evaluating whether these techniques are sufficiently feasible, cost-effective, and repeatable to be applied in large programs. The goal of this study was to design and test an image-interpretation approach for collecting plant community composition and ground cover data appropriate for local and continental-scale assessment and monitoring of grassland, shrubland, savanna, and pasture ecosystems. We developed a geographic information system image-interpretation tool that uses points classified by experts to calibrate observers, including point-by-point training and quantitative quality control limits. To test this approach, field data and high-resolution imagery (3 cm ground sampling distance) were collected concurrently at 54 plots located around the USA. Seven observers with little prior experience used the system to classify 300 points in each plot into ten cover types (grass, shrub, soil, etc.). Good agreement among observers was achieved, with little detectable bias and low variability among observers (coefficient of variation in most plots 0.9), suggesting regression-based adjustments can be used to relate image and field data. This approach could extend the utility of expensive-to-collect field data by allowing it to serve as a validation data source for data collected via image interpretation.

AN - 1015753627; 22548418 AB - Phosphorus-rich manure biochar has a potential for stabilizing Pb and other heavy metal contaminants, as well as serving as a sterile fertilizer. In this study, broiler litter biochars produced at 350 and 650 °C were employed to understand how biochar's elemental composition (P, K, Ca, Mg, Na, Cu, Pb, Sb, and Zn) affects the extent of heavy metal stabilization. Soil incubation experiments were conducted using a sandy, slightly acidic (pH 6.11) Pb-contaminated (19906 mg kg(-1) total Pb primarily as PbCO(3)) small arms range (SAR) soil fraction (<250 μm) amended with 2-20 wt % biochar. The Pb stabilization in pH 4.9 acetate buffer reached maximum at lower (2-10 wt %) biochar amendment rate, and 350 °C biochar containing more soluble P was better able to stabilize Pb than the 650 °C biochar. The 350 °C biochar consistently released greater amounts of P, K, Mg, Na, and Ca than 650 °C biochar in both unbuffered (pH 4.5 sulfuric acid) and buffered (pH 4.9 acetate) systems, despite 1.9-4.5-fold greater total content of the 650 °C biochar. Biochars, however, did not influence the total extractable Pb over three consecutive equilibration periods consisting of (1) 1 week in pH 4.5 sulfuric acid (simulated leaching by rainfall), (2) 1 week in pH 4.9 acetate buffer (standard solution for toxicity characteristic leaching procedure), and (3) 1 h in pH 1.5 glycine at 37 °C (in vitro bioaccessibility procedure). Overall, lower pyrolysis temperature was favorable for stabilizing Pb (major risk driver of SAR soils) and releasing P, K, Ca, and other plant nutrients in a sandy acidic soil.

Previous studies suggested that variation in the FCI among individuals and populations of fish prevents the identification of a single time point that can be used for all trout. In this study we confirmed the optimal time to apply pressure is 65 plus or minus 5% of the FCI. In addition, we found that variation in FCI of fish from a common environment can be within limits that allow a single time point to be established for that group of fish, if ova post ovulatory aging is taken into account. Aging of ova, either in vivo or in vitro, increased FCI to a degree that is a concern for tetraploid induction. The FCI was about 12min longer at 7days post ovulation, and 30min at 10-14days, than at 1day. The FCI for a group of fish was consistent throughout the spawning season. Survival to hatching and frequency of spinal abnormalities were similar for progeny of first and second generation tetraploid males, but survival was doubled and abnormalities reduced by approximately 90% in second generation tetraploid females compared with first generation females. All progeny of tetraploid by tetraploid crosses were determined to be tetraploids based on flow cytometry of embryonic cells.

AN - 1014113117; 22541005 AB - White snakeroot and rayless goldenrod cause "trembles" and "milk sickness" in livestock and humans, respectively. The toxin in white snakeroot and rayless goldenrod was identified in 1927 and 1930, respectively, as tremetol. It was reported that the toxin in white snakeroot disappears as it is dried and that completely dried plants were incapable of producing trembles or milk sickness. Conversely, it has been reported that the rayless goldenrod toxin was not destroyed by drying and that the plant is toxic either fresh or dry. In this study the concentrations of tremetone, dehydrotremetone, and structurally similar compounds were determined in white snakeroot and rayless goldenrod before and after various drying conditions. Tremetone, dehydrotremetone, and structurally similar compounds in rayless goldenrod and white snakeroot are most stable upon freeze-drying, followed by air-drying, and least stable upon oven-drying (60 °C). Also demonstrated is that tremetone is stable and that dried white snakeroot and rayless goldenrod are capable of inducing toxicosis in livestock.

(Lepidoptera: Noctuidae). AN - 993315657; 22228503 AB - The potential development of resistance to Bacillus thuringiensis (Bt) cotton and surging of non-targeted insects is a major risk in the durability of Bt plant technology. Midgut proteinases are involved in Bt activation and degradation. Proteinase inhibitors may be used to control a wide range of insects and delay Bt resistance development. Proactive action to examine proteinase inhibitors for synergistic interaction with Bt toxin and cloning of proteinase cDNAs for RNAi is necessary to make transgenic cotton more versatile and durable. A sublethal dose (15 ppb) of Cry1Ac, 0.5% benzamidine and 0.02% phenylmethylsulfonyl fluoride significantly suppressed midgut azocaseinase, tryptic and chymotryptic activities, and resulted in reductions in larval and pupal length and mass of Heliothis virescens. The combination of proteinase inhibitor and Bt suppressed 20-37% more larval body mass and 26-80% more enzymatic activities than the inhibitor only or Bt only. To facilitate knockdown-resistance-related proteinase genes, 15 midgut chymotrypsin cDNAs were sequenced. Most predicted chymotrypsins contained the conserved N-termini IVGG, three catalytic center residues (His, Asp and Ser), substrate specificity determinant (Ser or Gly) and cysteines for disulfide bridges. These putative chymotrypsins were separated into three distinct groups, indicating the diverse proteinases evolved in this polyphagous insect. H. virescens has evolved diverse midgut proteinase genes. Proteinase inhibitors have potential insecticidal activity, and the interaction of Bt with proteinase inhibitors is desirable for enhancing Bt toxicity and delaying resistance development. Intensive sequencing of chymotrypsin cDNAs will facilitate future functional examinations of individual roles in Bt toxicity and resistance development and facilitate targeted control using RNAi and/or proteinase inhibitors.

AN - 968107002; 21953740 AB - Many species in the Lupinus genus are poorly defined morphologically, potentially resulting in improper taxonomic identification. Lupine species may contain quinolizidine and/or piperidine alkaloids that can be acutely toxic and/or teratogenic, the latter resulting in crooked calf disease. To identify characteristic alkaloid profiles of Lupinus sabinianus, L. garfieldensis and L. sericeus which would aid in discriminating these species from each other and from L. sulphureus. Quinolizidine and piperidine alkaloids were extracted from herbarium specimens and recent field collections of L. sabinianus, L. garfieldensis and L. sericeus. The alkaloid composition of each species was defined using GC-FID and GC-MS and compared using multivariate statistics. Each of the three species investigated contained a diagnostic chemical fingerprint composed of quinolizidine and/or piperidine alkaloids. The alkaloid profiles of Lupinus sabinianus, L. garfieldensis and L. sericeus can be used as a tool to discriminate these species from each other and L. sulphureus as long as one considers locality of the collection in the case of L. sabinianus.

AN - 948892084; 22245061 AB - We assessed the aqueous toxicity mitigation capacity of a hydrologically managed floodplain wetland following a synthetic runoff event amended with a mixture of sediments, nutrients (nitrogen and phosphorus), and pesticides (atrazine, S-metolachlor, and permethrin) using 48-h Hyalella azteca survival and phytoplankton pigment, chlorophyll a. The runoff event simulated a 1h, 1.27 cm rainfall event from a 16 ha agricultural field. Water (1L) was collected every 30 min within the first 4h, every 4h until 48 h, and on days 5, 7, 14, 21, and 28 post-amendment at distances of 0, 10, 40, 300 and 500 m from the amendment point for chlorophyll a, suspended sediment, nutrient, and pesticide analyses. H. azteca 48-h laboratory survival was assessed in water collected at each site at 0, 4, 24, 48 h, 5 d and 7 d. Greatest sediment, nutrient, and pesticide concentrations occurred within 3h of amendment at 0m, 10 m, 40 m, and 300 m downstream. Sediments and nutrients showed little variation at 500 m whereas pesticides peaked within 48 h but at <15% of upstream peak concentrations. After 28 d, all mixture components were near or below pre-amendment concentrations. H. azteca survival significantly decreased within 48 h of amendment up to 300 m in association with permethrin concentrations. Chlorophyll a decreased within the first 24h of amendment up to 40m primarily in conjunction with herbicide concentrations. Variations in chlorophyll a at 300 and 500 m were associated with nutrients.

The current movement of these pathogens suggests that their incursion into the United States is imminent. The objective of this work was to identify effective application parameters to apply fungicides for protecting against wheat head scab and stem rust infection. Field trials were designed to evaluate the effect of spray volume, spray quality, and air assistance on spray deposition on sections of a wheat plant most susceptible to infection. Following application of a fluorescent tracer tank mix, plant samples were collected from each of ten plants in each replicate for each treatment. Plant sections sampled included Heads, Flag Leaf, Flag Leaf+1 (sometimes referred to as the penultimate leaf or Flag Leaf-1), and the Stem between the Head and Flag Leaf+1. There were no significant differences between treatments in the amount of spray on the stem sections but the higher volume (140 L/ha) treatments tended to produced the highest deposits across all plant parts compared to the lower volume (94 L/ha) treatments. Significant differences between treatments were observed for the amount of spray found on Head and Leaf sections. Directing the spray and air stream 30 degree forward increased deposits of Fine spray quality droplets on the Head sections but reduced deposits on the more horizontal Flag leaves. Spray coverage measured on artificial targets with a vertical and cylindrical shape (to simulate the wheat head target) also increased when the air/spray stream was directed 30 degree forward compared to a vertical delivery. Spray coverage also was higher for treatments made at the same spray volume and air outlet speed using a Fine quality spray nozzle compared to a Medium quality spray nozzle. These results demonstrate that different application parameters may be required depending on the specific section of the wheat plant that requires protection.

Disease evaluations were conducted at the Tropical Agriculture Research Station in Isabela, Puerto Rico, during the 2005 and 2009 growing seasons. Twenty-one accessions were rated as resistant across replications and growing seasons and showed reddening of inoculated leaves without acervuli development. These accessions represent new sources of anthracnose resistance for sorghum improvement. Fewer accessions were rated as resistant from the drier, northern Niono district as compared to the San and Segou districts that receive greater annual rainfall, suggesting an ecogeographic association. Additionally, susceptible accessions from the Niono district frequently showed higher mean disease severities than susceptible accessions from the San and Segou districts. Accessions classified as race guinea were more frequently rated as resistant compared to race durra accessions. Mean disease severities were also significantly lower for race guinea accessions. The majority of accessions in the collection were race guinea with most durra accessions collected from the Niono district. However, the frequency of resistant guinea accessions was similar across districts. These results indicate ecogeographic origin and race classification could be used to select accessions for anthracnose screening and to identify regions where resistance is more prevalent for the acquisition of additional anthracnose-resistant germplasm.

Hard mast indices provide a relative ranking and basis for comparison of within- and between-year acorn crop size at a broad scale, but do not provide an estimate of actual acorn yield-the number of acorns that can potentially be produced on a given land area unit based on the species, number, and diameter at breast height (dbh) of oak trees present. We used 10 years of acorn production data from 475 oak trees to develop predictive models of potential average annual hard mast production by five common eastern oak species, based on tree diameter and estimated crown area. We found a weak (R super(2)=0.08-0.28) relationship between tree dbh and acorn production per unit crown area for most species. The relationship between tree dbh and acorn production per tree was stronger (R super(2)=0.33-0.57). However, this is because larger-dbh trees generally have larger crowns, not because they have a greater capacity to produce more acorns per unit crown area. Acorn production is highly variable among individual trees. We estimated that dbh of at least 60 dominant or codominant oak trees per species should be randomly sampled to obtain an adequate representation of the range of dbhs ( greater than or equal to 12.7cm dbh) in a given forest area, and achieve precise estimates when using these equations to predict potential acorn production. Our predictive models provide a tool for estimating potential acorn production that land managers and forest planners can apply to oak inventory data to tailor estimates of potential average annual acorn production to different forest management scenarios and multiple spatial scales.

We studied nesting habitat for the mountain plover (Charadrius montanus) in relation to prescribed fire, grazing by large herbivores (cattle), and grazing by black-tailed prairie dogs (Cynomys ludovicianus) in the shortgrass steppe of northeastern Colorado. Breeding mountain plovers primarily occurred on black-tailed prairie dog colonies or areas burned during the previous dormant season. Vegetation surrounding mountain plover nests and foraging locations was characterized by a fine-scale mosaic of prostrate (35% bare soil in a given square meter, with this fine-scale pattern distributed over a broad (>100-m radius) area. Mountain plovers rarely occupied grassland lacking prairie dogs or recent fire, but those that did selected sites with similar vegetation height and bare soil exposure as sites on burns and prairie dog colonies. Vegetation structure at mountain plover-occupied sites was also similar to random sites on burns and prairie dog colonies, but differed substantially from sites managed only with cattle. Intensive cattle grazing at twice the recommended stocking rate during spring (Mar-May) or summer (May-Oct) for 6 years produced significantly less bare soil than burns and prairie dog colonies, particularly following years with average or above-average precipitation. Thus, intensive cattle grazing did not substitute for prairie dog grazing or fire in terms of effects on vegetation structure and mountain plover habitat. Both prescribed burning and increased size and distribution of black-tailed prairie dog colonies appear to be effective and complementary means to manage for mountain plover breeding habitat in shortgrass steppe. Provision of mountain plover habitat has tradeoffs with traditional management for livestock production. Thus, managers need to clearly define desired outcomes for management to provide multiple ecosystem goods and services. [copy 2012 The Wildlife Society.

This bacterium produces a group of twenty-one enterotoxins (SEs). These enterotoxins have two separate but related biological activities. They cause gastroenteritis and function as superantigens that activate large numbers of T cells. The current method for detection of enterotoxins actiuty is an in vivo monkey or kitten bioassay; however, this method is not practical to test on a large number of samples. Several immunological assays have been developed however, but these assays cannot distinguish between active toxin which causes food poisoning and inactive toxin, which can bind antibody, but shows no toxicity. The current study demonstrates that short term ex vivo exposure of primary naive CD4 super(+) T-cells or splenocytes to SEA induces differential expression and secretion of tumor necrosis factor (TNF) protein. We used immunomagnetic beads coated with anti-SEA antibody to specifically isolate SEA from food. After the eluted toxin was added to the cells SEA biological activity was measured by quantifying TNF protein expression or secretion.

P. expansum mycelial growth was greatest on lyophilized lyophilised fruit tissue and the highest PG activity occurred in apple pectin medium. Nitrogen source influenced PG activity and was highest with ammonia while the greatest mycelial mass was supported by glutamate or glutamine. PG activity and mycelial mass peaked 5 five days after inoculation as polyuronide content decreased and the pH and ammonium levels increased in apple pectin medium. A single active PG isozyme with an isoelectric point of similar to 7.6 was produced in apple pectin medium and a partial cDNA clone was obtained that was most homologous to the pggII gene from Penicillium. griseoroseum. The results from this study indicate that P. expansum can modulate the activity of PG in response to nutrient sources and ambient pH through signalling pathways that modulate nutrient acquisition, uptake and metabolism.

New management protocols for temperate grasslands are needed to reduce the risk of P transport to surface water. The effects of three land-use treatments on soil characteristics related to P runoff were investigated using small watersheds with 8% slope near Booneville, Arkansas, U.S. The land use treatments were (1) haying of bermudagrass overseeded with winter annual forage (ryegrass or rye), (2) rotationally grazed, and (3) rotationally grazed with 12-m-wide tree buffer on the downhill portion of the plot. Plots and trees were established in 2003. Annual spring application of poultry litter (5.6 Mg ha super(-1)) to the hayed or grazed portions of the plots was started in 2004. Grazing treatments were imposed shortly thereafter. By the summer of 2008 (4 years of treatments), soil concentrations of Bray 1-extractable P and soluble reactive P had increased significantly from approximately 40 and 4 mg P kg super(-1) soil, respectively, to more than 200 and 30 mg P kg super(-1) soil, respectively, in the areas of the plots receiving poultry litter.

The soil collected from the forested riparian buffer in 2008 had similar soil bulk densities and Bray 1-extractable P concentrations as the plots did in 2003 before treatments were imposed.

Essential oil extracted from rhizomes and plant extracts of ornamental ginger lily (Hedychium spp.) were evaluated for their antifungal activity against two fungi, Aspergillus flavus and Fusarium verticillioides, that produce two major classes of mycotoxins, aflatoxin, and fumonisin, respectively, on several crops. Essential oil or leaf extracts from several Hedychium species and varieties totally inhibited the growth of pre-germinated spores of A. flavus and F. verticillioides. Control of these two fungi by aqueous extracts of rhizome was not effective, although a reduced number of colonies was observed. In view of these results, essential oils or crude leaf extracts from Hedychium spp. need to be considered for the control of mycotoxin-producing fungi under storage conditions.

A six-year field study was conducted from 2004 to 2009 at Stoneville, MS, to examine the effects of rotating glyphosate-resistant and glufosinate-resistant corn under reduced tillage conditions on weed control, soil weed seedbanks, and yield. The four rotation systems were glyphosate-resistant and glufosinate-resistant corn grown continuously and in rotation with two herbicide programs, post-emergence-only herbicides (POST) and preemergence herbicides followed by POST (PRE + POST). Control of 13 predominant weed species in glyphosate-resistant and glufosinate-resistant corn was >95%, regardless of herbicide program, with the exception of johnsongrass and yellow nutsedge, both perennial weeds. Johnsongrass and yellow nutsedge control was lower in the continuous glufosinate-resistant corn system compared with other rotation systems. Yellow nutsedge control was higher with the PRE + POST (89% to 99%) compared with the POST-only (72% to 86%) treatment. Corn yields were similar regardless of rotation when a corn cultivar stacked with both glyphosate-resistant and glufosinate-resistant traits was used. The PRE + POST program gave 5% to 10% higher yield than the POST-only program in four of six years. The seedbank for yellow nutsedge and predominant grass and broadleaf weeds was not significant among the four rotation systems. Seedbanks for grasses and yellow nutsedge were higher in the POST-only program (20.5 and 1.8 per core of 678 cm super(3), respectively) compared with the PRE + POST program (9.5 and 0.4 per core, respectively). These results indicate that johnsongrass and yellow nutsedge control could be reduced in continuous glufosinate-resistant corn and could be mitigated by rotating with glyphosate-resistant corn.

Three harvesting schedules and a control treatment (no straw harvest) were replicated six times on 24 plots (0.18 ha each), and compared to determine harvesting effects on water content of the soil vadose zone in an established (16 yr) loblolly (Pinus taeda L.) plantation (3.0 1.5 m super(2) tree spacing). Pine straw harvesting tended to decrease volumetric soil water content (%) at depths below 20 cm, but the effect was significant (p < .05) only at the 50-cm depth in Weeks 3 and 4 (late June) of the study, when water content at this depth averaged 20.9% for soils where straw was harvested annually, and 30.2% for soils where the straw was never harvested (control). In soils where pine straw had been allowed to accumulate for at least a year after the previous harvest, average water content was not significantly different than in the control plots. Therefore, pine straw harvesting can potentially lengthen drought-stress periods for loblolly pine on some soils during the 1st yr after pine straw has been removed.

In order to minimize the risk of nitrogen (N) loss between application and crop uptake in the spring, university extension publications and industry professionals often make recommendations based on soil temperature. The objective of this research, therefore, was to determine how soil temperature affects N losses in runoff and leachate, and assess overwinter N losses based on application date and soil temperature. Phosphorus losses are discussed in a separate article. Dairy manure was surface-applied to a channery silt loam soil contained in lysimeters at soil temperatures of 15.7 degree C, 4.8 degree C, and -1.1 degree C, which corresponded to early fall (Oct. 22), late fall (Nov. 17), and winter (Dec. 15) applications, respectively. Nitrogen losses were determined during a series of rainfall simulations and natural precipitation events from October 2009 through March 2010. The soil temperature between manure application and the first rainfall-runoff event three days after application was held constant and significantly influenced N loss. As the soil temperature decreased, losses of NH(4)-N, organic N, and total N exponentially increased. The form of N losses was also significantly impacted by application date and overwinter soil temperature. Early fall application of manure resulted in significant overwinter NO(3)-N losses, while the winter-applied manure had significantly more overwinter NH(4)-N losses. Results of this research show that there are trade-off risks associated with manure application in the fall and winter and that these trade-offs need to be considered in manure management planning in order to enhance N retention and help reduce the risk of overwinter N losses.

Water application rates under center-pivot irrigation commonly exceed the infiltration rate, especially near the end of the system lateral. This can lead to off-site runoff and erosion, but more importantly results in field-scale nonuniform water infiltration that can substantially reduce water use efficiency of these irrigation systems. The objective of this study was to develop a sealing soil infiltration model that considers transient soil seal formation on a 30 min or less time scale and can potentially be applied to center-pivot sprinkler irrigation systems. A sealing soil infiltration model was developed using an explicit finite difference solution scheme with a transient soil seal formation model, which is unique from other studies in that it explicitly uses droplet specific power as the driving factor for formation of a soil surface seal. The form of the transient seal formation model is also unique in that it is expressed as a rational function of specific power rather than an exponential decay function of droplet kinetic energy. The model was applied to published runoff data from two rainfall simulation studies with varying droplet kinetic energies and application rates on three soils. The sealing soil infiltration model represented the measured infiltration rates very well for all rainfall simulator tests. The transient soil seal formation model uses three parameters, one of which is an empirical parameter representing the susceptibility of the soil to aggregate breakdown that was constant for a given soil. A second model parameter, final saturated hydraulic conductivity of the surface seal, was well correlated to droplet specific power for a given soil. Application of the model to center-pivot irrigation will require the development of a model for estimating droplet specific power and application rate profiles from center-pivot sprinklers for a range of sprinkler designs, flow rates, operating pressures, spacings, and heights.

In order to minimize the risk of nutrient loss, recommendations are often based on soil temperature, since biological activity has been shown to decrease substantially at temperatures less than 10 degree C. These recommendations are often targeted toward reducing nitrogen (N) losses; thus, a smaller body of information is available on the fate of phosphorus (P) from fall and winter applied manure. The objective of this research was to determine how soil temperature affects P loss in runoff and leachate, and assess overwinter P losses based on application date and soil temperature. Nitrogen losses are discussed in a separate article. Dairy manure was surface applied to a channery silt loam soil contained in lysimeters at soil temperatures of 15.7 degree C, 4.8 degree C, and -1.1 degree C, which represented early fall, late fall, and winter applications, respectively. Phosphorus losses were determined during a series of rainfall simulations and natural precipitation events from October 2009 through March 2010. Phosphorus losses were significantly influenced by the soil temperature at the time of manure application and first rainfall-runoff event. As the soil temperature decreased, losses of DRP, TDP, and total P increased. Overwinter losses were also significantly impacted by soil temperature. The winter treatment had two times higher total P losses compared to the manure applied during the early fall. Results of this research show that soil temperature is important for determining P losses and that incorporating quantitative tools, such as soil temperature, into manure management plans could enhance P retention and help reduce the risk of overwinter P losses.

Yet this production is threatened by frequent short-term regional drought. This drought threat can be mitigated by properly managed irrigation. In this study on Tifton 85 bermudagrass, irrigation management, nitrogen fertility levels, and harvest interval were evaluated for their impact on hay quality and yield. The experimental treatments were arrayed in a split-plot design with harvest interval as the main treatment; irrigation by nitrogen (N) levels were the subplots. Treatments had four replicates and were repeated for two years. The optimal irrigation rate was set to maintain soil water potentials below -30 kPa. When needed, the full irrigation treatment received a 12.5 mm irrigation application. The reduced irrigation treatments received water at rates of 0%, 33%, and 66% of the full irrigation rate. In addition, each irrigation treatment had nitrogen rates of 168, 336, and 504 kg N ha(-1). The irrigation and nitrogen treatments were harvested at four-week or eight-week intervals. Total harvests per year ranged from three to six. Over both years and for all harvests, there was no irrigation-nitrogen interaction for hay yield. Over all harvests, nitrogen significantly increased bermudagrass hay yield, nutrient concentrations, and forage quality. Forage quality was higher for the four-week harvest interval. Throughout the study, forage quality was maintained within desired industry standards. When irrigation was required, it significantly increased hay yield. During these periods, the four-week and eight-week 100% irrigation treatments yielded 612 and 1600 kg ha(-1) greater, respectively, than the non-irrigated treatments. The four-week harvest interval was more sensitive to irrigation. Additionally, we observed a linear relationship between non-irrigated bermudagrass hay yields and average soil water potential. As soil water was depleted, non-irrigated hay yields decreased 31 kg ha(-1) per kPa. Timely supplemental irrigation to maintain soil water potentials above -30 kPa can increase bermudagrass yields. Thus, irrigation management should be critically assessed for its potential role in sustaining hay production in the southeastern Coastal Plain.

An experimental variable-rate air-assisted sprayer implemented with a high-speed laser scanning sensor was developed to control the spray output of individual nozzles in real time. The sprayer consisted of a laser scanning sensor control system and an air and liquid delivery system. Each nozzle in the delivery system, coupled with a pulse width modulated (PWM) solenoid valve, achieved variable-rate delivery based on occurrence, height, and width of the target tree and its foliage density. Other components of the sensor control system included a unique algorithm for variable-rate control that instantaneously processed measurements of the canopy surfaces. To determine system delay time, a high-speed video camera was used to record the time period between sensor detection of the canopy and nozzle activation. Spray deposition uniformity inside canopies was verified by quantifying spray coverage inside four ornamental nursery trees of different sizes and canopy densities at 3.2 and 6.4 km h(-1) travel speeds. Test results demonstrated that differences in spray coverage inside the canopies of these four trees in the spraying direction were not statistically significant, even though these trees had different structures, canopy volumes, and foliage densities. The canopy volume and foliage density measured with the algorithm developed for the laser sensor-controlled detection system exhibited little variation between the two travel speeds. Design criteria for the sensor-controlled system in the experimental sprayer were acceptable for variable-rate application, having great potential for spray volume and drift reduction, and thus reducing environmental impact.

Feeding practices influence the excretion of starch, fiber, nitrogen (N), and sulfur (S) in manure, thereby affecting nutrient content and the production of ammonia (NH(3)) and odorous compounds. Wet distillers grains with solubles (WDGS) are a common and economical ingredient in feedlot diets. WDGS are high in protein, fiber, phosphorus (P), and S but low in starch. The objective of this study was to compare NH(3) concentration in the air and nutrients and volatile organic compounds (VOC) concentration in manure between two dietary treatments fed to feedlot cattle. Five pens of feedlot cattle were fed diets containing 14% to 35% WDGS and five pens were fed a corn-based diet with no ethanol byproducts (Control). Each pen had twelve sampling locations (N=120) where air and manure samples were collected from the feedlot surface. Air samples were analyzed for NH(3) concentration. Manure samples were analyzed for dry matter, pH, volatile solids, VOC, and nutrient composition (N, P, and S). Concentrations of P and S in manure and NH(3) in the air were higher in pens fed WDGS compared to pens fed the control diet. Concentrations of VOC were similar across both treatments.

Drainage water from tile-drained, irrigated agricultural land is degraded water that is often in large supply, but the long-term impact and sustainability of its reuse on soil is unknown. Similarly, nothing is known of the ramifications of terminating drainage water reuse. The objective of this study is (i) to monitor the long-term impact on soil chemical properties and thereby the sustainability of drainage water reuse on a marginally productive, saline-sodic, 32.4 ha field located on the west side of California's productive San Joaquin Valley and (ii) to assess spatially what happens to soil when drainage water reuse is terminated. The monitoring and assessment were based on spatial chemical data for soil collected during 10 years of irrigation with drainage water followed by 2 years of no applied irrigation water (only rainfall). Geo-referenced measurements of apparent soil electrical conductivity (EC sub(a)) were used to direct the soil sampling design to characterize spatial variability of impacted soil properties. Chemical analyses of soil samples were used (i) to characterize the spatial variability of salinity, Na, B, and Mo, which were previously identified as critical to the yield and quality of Bermuda grass (Cynodon dactylon(l.) Pers.) grown for livestock consumption and (ii) to monitor their change during the 12 year study. Soil samples were taken at 0.3 m increments to a depth of 1.2 m at each of 40 sample sites on five occasions: August 1999, April 2002, November 2004, August 2009, and May 2011. Drainage water varying in salinity (1.8-16.3 dS m super(-1)), SAR (5.2-52.4), Mo (80-400 mu g L super(-1)), and B (0.4-15.1 mg L super(-1)) was applied from July 2000 to June 2009. Results indicate that salts, Na, Mo, and B were leached from the root zone causing a significant improvement in soil quality from 1999 to 2009. Salinity and SAR returned to original levels or higher in less than two years after termination of irrigation. Boron and Mo showed significant increases. Long-term sustainability of drainage water reuse was supported by the results, but once application of irrigation water was terminated, the field quickly returned to its original saline-sodic condition.

Also, measuring whole assemblage responses such as metabolism can mask species-specific responses, as some species may decrease and others increase metabolic activity. Physiological responses can add information to compositional data, and may be a more sensitive indicator of effect. It is difficult, however, to separate individual species for biochemical analyses. Agricultural runoff often contains multiple pollutants that may alter algal assemblages in receiving waters. It is unclear how mixtures containing potential algal growth stimulators and inhibitors (e.g., nutrients and herbicides) alter algal assemblage structure and function. In research presented here, algal biofilms were exposed to nutrients, atrazine, and their mixtures, and assemblage-level structural and functional changes were measured. Synchrotron infrared microspectroscopy (IMS) was used to isolate the biochemical changes within individual cells from a dominant species of a green alga (Mougeotia sp.), a diatom (Navicula sp.), and a cyanobacterium (Hapalosiphon sp.). At the assemblage level, mixtures generally increased algal biovolume, decreased chlorophyll a, and had no effect on metabolism or ammonium uptake. Navicula had a strong negative response to atrazine initially, but later was more affected by nutrients. Hapalosiphon responded positively to both atrazine and nutrients, and Mougeotia did not exhibit any biochemical trends. Generally, biochemical changes in each species were similar to cells experiencing low stress conditions, with increased relative protein and decreased relative lipid. IMS provided direct evidence that individual species in a natural biofilm can have unique responses to atrazine, nutrients, and mixtures. Results suggest that the initial benthic community composition should have a strong influence on the overall impact of agricultural pollutants.

To reverse this trend, sagebrush-reducing treatments often are applied with the goal of increasing herbaceous vegetation. Mechanical mowing is a sagebrush-reducing treatment that commonly is applied; however, information detailing vegetation responses to mowing treatments generally are lacking. Specifically, information is needed to determine whether projected increases in perennial grasses and forbs are realized and how exotic annual grasses respond to mowing treatments. To answer these questions, we evaluated vegetation responses to mowing treatments in mountain big sagebrush plant communities at eight sites. Mowing was implemented in the fall of 2007 and vegetation characteristics were measured for 3 yr post-treatment. In the first growing season post-treatment, there were few vegetation differences between the mowed treatment and untreated control (P>0.05), other than sagebrush cover being reduced from 28% to 3% with mowing (P0.05). These results suggest that the abundance of sagebrush might not be the factor limiting some herbaceous plant functional groups, or they respond slowly to sagebrush-removing disturbances. However, this study suggests that mowing can be used to increase herbaceous vegetation and decrease sagebrush in some mountain big sagebrush plant communities without promoting exotic annual grass invasion.

Nonionic soil surfactants (wetting agents) have been shown to be effective in enhancing infiltration and improving root-zone water reserves in water-repellent soils. However, the application of soil surfactants in wildland ecosystems can be logistically and economically prohibitive. In this study, we evaluated a potential solution for applying soil surfactants using seed coating technology. Through this technology, the seed is used as a carrier for the soil surfactant. After planting, water transfers the surfactant from the seed into the soil where it ameliorates the water repellency within the seed's microsite. The objectives of this research were 1) to establish the efficacy of a surfactant seed coating (SSC) in ameliorating soil water repellency, and 2) to determine the influence of SSC on seedling emergence and plant survival. To accomplish the first objective, detailed soil column experiments were conducted in the laboratory on water-repellent soil obtained from a burned pinyon-juniper (Pinus-Juniperus spp.) woodland. The second objective was met through greenhouse testing of SSC applied to crested wheatgrass and bluebunch wheatgrass seed, using the same soil as used in the first objective. Results indicate that SSC increased soil water infiltration, percolation, and retention. This technology had no influence on seedling emergence for crested wheatgrass, but SSC improved bluebunch wheatgrass (Pseudoroegneria spicata [Pursh] A. Love) emergence threefold. Plant survival was dramatically improved by the SSC. Only 0.75% of the seedlings that grew from noncoated seed survived to the end of the study, whereas 37% of the plants survived in the SSC treatment. Overall, these results indicate that it may be plausible for SSC to improve postfire restoration efforts by restoring soil hydrologic function and increasing seedling emergence and early seedling development.

We argue that creating a database that links state-and-transition models (STMs) to spatial units is a valuable management tool for structuring ground-based observations, management planning for landscapes, and for housing information on the responses of land areas to management actions. To address this need, we introduce a multifactor classification system based on ecological sites and STMs that is directly linked to recent concepts of vegetation dynamics in rangelands. We describe how this classification was used as a basis for creating a spatial database and maps of ecological states. We provide an example of how the classification and mapping has been applied in over 1.2 million ha of public rangelands in southern New Mexico using aerial photo interpretation supplemented with existing inventory data and rapid field assessments. The resulting state map has been used by the Bureau of Land Management: 1) to design landscape-level shrub control efforts, 2) to structure and report district-wide rangeland health assessments, and 3) to evaluate locations for energy development. We conclude by discussing options for the development of state maps and their current limitations, including the use of satellite imagery and concepts for defining states. We argue that cataloging ecological states in a spatial context has clear benefits for rangeland managers because it connects STM concepts to specific land areas. State mapping provides a means to generate and store spatially explicit data resulting from tests of the propositions in STMs and conservation practices.

This woodpecker responds positively to large-scale fire disturbances and may be at risk from logging and post-fire management. With 100 radio-locations of four adult males, we used resource-selection probability functions in logistic form in an information-theoretic framework to model the Black-backed Woodpecker's selection of foraging habitat at fine and coarse spatial scales. Fine-scale data included characteristics of the foraging tree (tree level) and local habitat surrounding foraging trees (plot level, 0.04 ha), whereas coarse-scale data (224-778 ha) included patch characteristics within home ranges. Model selection by Akaike's information criterion identified a multi-scale model containing tree- and plot-level covariates, and their interaction, as the best model to characterize foraging trees. The positive effect of interaction between foraging-tree diameter and plot-level tree density suggested that foraging Black-backed Woodpeckers select both patches with dense trees and larger-diameter trees. Fire severity was not important, possibly because of the time since fire and the birds' habit of foraging on recently dead trees in adjacent unburned forests. Salvage logging that retains large-diameter trees in clumped distributions is most likely to provide long-term foraging habitat for Black-backed Woodpeckers in dry coniferous forests of the interior western U.S. Following wildfire, conservation of forest patches containing weakened trees may extend the suitability of habitat for foraging Black-backed Woodpeckers by up to 8 years.

A major goal in applied tri-trophic research has been to determine whether breeding for host plant resistance traits can be combined with biological control to develop a more comprehensive control strategy. An important component of developing such a strategy is understanding how host resistance traits affect natural enemy-prey interactions for important pest insects. Here we examine the influence of genotypic variation in stem solidity, the primary trait conferring resistance against the wheat stem sawfly, Cephus cinctus, on parasitism of this major pest of wheat by its native braconid parasitoids. To do so, we conducted a field experiment in which we established replicate plots of 23 wheat genotypes that varied in levels of stem solidity, and quantified herbivore abundance and levels of parasitism across three sites in two years. Increasing stem solidity was associated with an approximately four-fold reduction in average parasitism rates, both across experimental plots and across wheat genotypes. Our analyses suggest that these effects were primarily direct, rather than indirectly mediated via effects of stem solidity on herbivore infestation levels or density. Interestingly, wheat genotype also had a significant influence on levels of parasitism, independent of its effects on stem solidity. Overall, our results suggest that although increasing stem solidity generally reduces parasitism, significant genotypic variability in average parasitism levels exist within solidity categories. Thus it may be possible to select resistant solid stemmed genotypes that also maintain relatively high parasitism levels. To our knowledge, our study is among the first to demonstrate a strong direct effect of genotypic variation in stem solidity on parasitism of grass mining insects, with important applied implications.Original Abstract: Die Merkmale von Wirtspflanzen konnen eine bedeutsame Rolle spielen, indem sie die Wichtigkeit, Richtung und Intensitaet von tri-trophischen Interaktionen sowohl ueber direkte als auch indirekte Kanaele steuern. Ein wichtiges Ziel von angewandten tri-trophischen Forschungen ist es, zu bestimmen, ob die Zucht auf Resistenzmerkmale der Wirtspflanze mit biologischer Kontrolle kombiniert werden kann, um eine umfassendere Kontrollstrategie zu entwickeln. Eine wichtige Komponente der Entwicklung einer solchen Strategie ist zu verstehen, wie Resistenzmerkmale des Wirtes die natuerlichen Feind-Beute-Interaktionen bei wichtigen Schadinsekten beeinflussen. Hier untersuchen wir den Einfluss von genotypischer Variabilitaet in der Staengelfestigkeit, die Resistenz gegen die Weizenhalmwespe Cephus cinctus vermittelt, auf die Parasitierung dieses wichtigen Weizenschaedlings durch seine einheimischen Parasitoide (Bracon spp.). Hierzu unternahmen wir ein Freilandexperiment, in dem wir replizierte Flaechen mit 23 Weizengenotypen, die hinsichtlich der Staengelfestigkeit variierten, einrichteten und dort die Abundanz der Herbivoren und den Grad der Parasitierung an drei Standorten und in zwei Jahren quantifizierten. Zunehmende Staengelfestigkeit war mit einer ungefaehr vierfachen Reduktion der durchschnittlichen Parasitierungsraten verbunden, sowohl im Vergleich der Experimentalflaechen wie im Vergleich der Weizengenotypen. Unsere Untersuchungen legen nahe, dass diese Effekte ueberwiegend direkt waren, und eher nicht indirekt durch Einfluesse der Staengelfestigkeit auf die Befallsraten oder Siedlungsdichten der Herbivoren vermittelt wurden. Interessanterweise hatte der Weizengenotyp einen signifikanten Einfluss auf die Parasitierung, unabhaengig von seinem Effekt auf die Staengelfestigkeit. Insgesamt legen unsere Ergebnisse nahe, dass, obwohl zunehmende Staengelfestigkeit allgemein die Parasitierung reduziert, innerhalb der Festigkeitsklassen eine signifikante genotypische Variabilitaet bei den durchschnittlichen Parasitierungsraten besteht. Es konnte deshalb moglich sein, resistente Genotypen mit festen Staengeln zu zuechten, die auserdem hohe Parasitierungsgrade erlauben. Soweit uns bekannt, ist unsere Untersuchung eine der ersten, die einen starken direkten Effekt auf die geotypische Variabilitaet der Staengelfestigkeit auf die Parasitierung von staengelminierenden Insekten gezeigt hat - und dies mit wichtigen Konsequenzen fuer den angewandten Bereich.

Boron is an element with a narrow concentration range between deficiency and toxicity for plants. Knowledge of the B concentrations in soil solution and transport of B out of the root zone is essential for management of wastewaters. Prediction of B concentrations in the root zone requires consideration of soil adsorption and desorption of B, which are dependent on soil properties and solution composition, especially pH. We examine B transport in soil by first applying a 0.08-mmol L (super -1) B solution to three arid-land soils from southern California and subsequently leaching the soils with a low B solution. The experiment was conducted with irrigation water at pH 6.0 and 9.0. The data showed that transport was highly pH dependent. Results from the column experiments were generally well predicted using the UNSATCHEM transport model with the B subroutine that includes the constant capacitance model and prediction of the model constants for each soil based on the specific soil properties. Use of a single set of average constants for all soils in combination with a calculated surface area provided a less satisfactory fit to the experimental data, especially at elevated pH. These results indicate that B transport can be predicted without the need for time-consuming and soil-specific determinations of B adsorption characteristics if we utilize predictive relations to predict the CCM constants from individual soil properties.

Heat release rate, peak heat release rate, temperature at peak heat release rate, heat release capacity, total heat release and char yield were determined. The peak heat release rate and total heat release results demonstrated that nonwoven fabrics treated with a formulation having higher diammonium phosphate and no dimethylol dihydroxyethyleneurea were superior to those treated with a formulation containing dimethylol dihydroxyethyleneurea. Nonwoven fabrics treated with these formulations were both superior to the nonwoven fabrics treated with a commercially available flame retardant formulation. These results were supported by the percentages of phosphorus and nitrogen on these fabrics, confirming that P-N synergism imparts high flame retardancy to the nonwoven fabrics. Grey cotton (untreated) consistently showed better flame resistance than (untreated) bleached cotton. As a result, its flame retardant products had lower heat release rate/peak heat release rate and other flammability characteristics than those of the bleached cotton. Additionally, grey cotton is softer than bleached cotton and saves the cost of bleaching and waste disposal. These three flame retardant formulations were used primarily to treat the cotton component of the nonwoven blend to make it flame retardant without flame retardant improvement for the polymer component.

Although Brucella abortus strain RB51 vaccination protects bison against experimental challenge, the effect of booster vaccinations was unknown. This study characterized immunologic responses after dart or booster vaccination of bison with Brucella abortus strain RB51. In two studies, 8- to 10-month-old female bison were inoculated with saline (n = 14), hand vaccinated with 1.1 1010 to 2.0 1010 CFU of RB51 (n = 21), or dart vaccinated with 1.8 1010 CFU of RB51 (n = 7). A subgroup of hand vaccinates in study 1 was randomly selected for booster vaccination 15 months later with 2.2 1010 CFU of RB51. Compared to single vaccinates, booster-vaccinated bison had greater serologic responses to RB51. However, there was a trend for antigen-specific proliferative responses of peripheral blood mononuclear cells (PBMC) from booster vaccinates to be reduced compared to responses of PBMC from single vaccinates. PBMC from booster vaccinates tended to have greater gamma interferon (IFN- gamma ) production than those from single vaccinates. In general, dart vaccination with RB51 induced immunologic responses similar to those of hand vaccination. All vaccinates (single hand, dart, or booster) demonstrated greater (P < 0.05) immunologic responses at various times after vaccination than nonvaccinated bison. Booster vaccination with RB51 in early gestation did not induce abortion or fetal infection. Our data suggest that booster vaccination does not induce strong anamnestic responses. However, phenotypic data on resistance to experimental challenge are required to fully assess the effect of booster vaccination on protective immunity.

The isolates were distinguished by biochemical tests and grouped by ARDRA to three clusters corresponding to three species (V. cholerae, Vibrio metschnikovii, and Aeromonas spp.). The identification of V. cholerae was confirmed by multiplex PCR using primer pairs targeted to ompW gene (membrane protein), ctxA gene (toxicity gene), and toxR gene (regulatory gene). None from the isolated V. cholerae from surface water contained ctxA gene; seven of them possessed toxR gene. Serotyping of V. cholerae isolates with polyvalent O antiserum and O/139 antiserum was negative.

An equation to estimate densities of flying insects per hectare is presented that uses the standard deviation (SD) of the vertical flight distribution, trapping time, the trap's spherical effective radius (ER), catch at the mean flight height (as estimated from a best-fitting normal distribution with SD), and an estimated average flight speed. Data from previous reports were used to estimate flight densities with the equations. The same equations can use traps with pheromone lures or attractive colors with a measured effective attraction radius (EAR) instead of the ER. In practice, EAR is more useful than ER for flight density calculations since attractive traps catch higher numbers of insects and thus can measure lower populations more readily. Computer simulations in three dimensions with varying numbers of insects (density) and varying EAR were used to validate the equations for density estimates of insects in the field. Few studies have provided data to obtain EAR, SD, speed, and trapping time to estimate flight densities per hectare. However, the necessary parameters can be measured more precisely in future studies.

Pathogenicity tests by inoculation onto 22 barley differential lines at seedling stage revealed 49 pathotypes. indicating a wide range of pathogenic diversity. Two-way analysis of variance of disease ratings revealed a significant difference in the virulence among isolates and in the resistance among barley lines, as well as in the interactions between the two, 'CI5791', 'Algerian', and 'Heartland' were three barley lines showing a high level of seedling resistance to all North Dakota isolates tested; however, many previously reported resistance genes have been overcome. Forty multilocus genotypes were identified from this set of isolates by genotyping at 13 simple-sequence repeat loci. High percentages of clonal cultures were detected in the samplings from 2005 and 2007 in Fargo and 2005 in Langdon. Using a clone-corrected sample set, the mean gene diversity (h) was estimated to be 0.58, approximately the same for both locations. The calculated Wright's F sub(ST) value is small (0.11) but was significantly >0, indicating a significant differentiation between the Fargo and Langdon populations. In the gametic disequilibrium test, only 3 of 78 possible pairwise comparisons over all isolates showed significant (P < 0.05) nonrandom association, suggesting a random mating mode. Our results suggest that the populations from the two locations are derived from a common source and undergo frequent recombination. This research provides important information for barley breeders regarding development and deployment of cultivars with resistance to net form net blotch in this region.

New opportunities in resistance breeding have arisen from the recent discovery of several necrotrophic effectors (NEs, also known as host-selective toxins) produced by S. nodorum, along with their corresponding host sensitivity (Snn) genes. Thirty-nine isolates of S. nodorum collected from wheat debris or grain from seven states in the southeastern United States were used to investigate the production of NEs in the region. Twenty-nine cultivars with varying levels of resistance to SNB, representing 10 eastern-U.S. breeding programs, were infiltrated with culture filtrates from the S. nodorum isolates in a randomized complete block design. Three single-NE Pichia pastoris controls, two S. nodorum isolate controls, and six Snn-differential wheat controls were also used. Cultivar-isolate interactions were visually evaluated for sensitivity at 7 days after infiltration. Production of NEs was detected in isolates originating in each sampled state except Maryland. Of the 39 isolates, 17 produced NEs different from those previously characterized in the upper Great Plains region. These novel NEs likely correspond to unidentified Snn genes in Southeastern wheat cultivars, because NEs are thought to arise under selection pressure from genes for resistance to biotrophic pathogens of wheat cultivars that differ by geographic region. Only 3, 0, and 23% of the 39 isolates produced SnToxA, SnTox1, and SnTox3, respectively, by the culture-filtrate test. A Southern dot-blot test showed that 15, 74, and 39% of the isolates carried the genes for those NEs. respectively; those percentages were lower than those found previously in larger international samples. Only two cultivars appeared to contain known Snn genes, although half of the cultivars displayed sensitivity to culture filtrates containing unknown NEs. Effector sensitivity was more frequent in SNB-susceptible cultivars than in moderately resistant (MR) cultivars (P = 0.008). although some susceptible cultivars did not exhibit sensitivity to NEs produced by isolates in this study and some MR cultivars were sensitive to NEs of multiple isolates. Our results suggest that NE sensitivities influence but may not be the only determinant of cultivar resistance to S. nodorum. Specific knowledge of NE and Snn gene frequencies in this region can be used by wheat breeding programs to improve SNB resistance.

Minimum spanning tree (MST) and unweighted-pair group method with arithmetic mean (UPGMA) analyses of VNTR data identified 237 different VNTR types, among which 14 prominent clusters of isolates could be identified. Cattle isolates from Texas segregated into three clusters: one comprised of field isolates from 1998 to 2005, one comprised of vaccination-associated infections, and one associated with an outbreak in Starr County in January 2011. An isolate obtained from a feral sow trapped on property adjacent to the Starr County herd in May 2011 clustered with the cattle isolates, suggesting a role for feral swine as B. abortus reservoirs in Starr County. Isolates from a 2005 cattle outbreak in Wyoming displayed VNTR-10 profiles matching those of strains recovered from Wyoming and Idaho elk. Additionally, isolates associated with cattle outbreaks in Idaho in 2002, Montana in 2008 and 2011, and Wyoming in 2010 primarily clustered with isolates recovered from GYA elk. This study indicates that elk play a predominant role in the transmission of B. abortus to cattle located in the GYA.

Smith) (Lepidoptera: Noctuidae), is composed of two sympatric, morphologically identical host strains (corn and rice) that differ in their distribution on different host plants. This suggests possible strain specificity in the use of host plants. However, although feeding studies published since 1987 have reported such developmental differences, the results were often contradictory, making generalizations about strain-specific physiological traits problematic. Here, we tested whether more consistent results could be obtained using several genetically characterized colonies when assayed in the same laboratory. We also assessed whether a commonly used meridic diet was more favorable to one strain and the potential this might have on altering the behavior of artificially raised colonies. Corn and rice strain colonies were characterized by cytochrome oxidase I (COI) strain markers and were subjected to feeding studies using corn (Zea mays L.), stargrass (Cynodon nlemfuensis Vanderyst variety nlemfuensis 'Florona'), and a meridic pinto bean diet. In 2005 bioassays, all colonies developed best on corn, whereas the meridic and stargrass diets were associated with more pronounced strain differences. However, bioassays conducted in 2010 using different colonies showed fewer differences between host strains. The limitations of feeding bioassays and the COI marker to identify host strains and the potential for unintended selection of corn strain traits when using a meridic diet are discussed.

However the production of macrocyclic trichothecene mycotoxins by this fungus presents significant safety concerns. It was discovered that trichothecenes are removed from M. verrucaria spores by repeated washes with water. These washed spores retained bioherbicidal efficacy against kudzu when tested in field trials and on sicklepod when tested under greenhouse conditions. Changes in the growth medium combined with washing spores with water resulted in greater than 95% reduction in roridin A and verrucarin A. Washing spores reduced trichothecene concentrations in spore preparations with no significant effect on plant biomass reduction, thus demonstrating the possibility of M. verrucaria formulations with improved safety to researchers, producers and applicators.

Black-tailed deer were thus allowed to browse among a controlled array of phytochemical cues in a series of experiments designed to evaluate foraging behavior at fine (within plot) and coarse (plot selection) scales. Within-plot diet selection experiments demonstrated that browse preference for individual western redcedar plants was a function of foliar monoterpene concentration. Individual plant palatability combined with momentary maximization foraging strategy promoted survival of heavily defended plants. Among-plot foraging experiments demonstrated that coarse-scale foraging preferences were strongly influenced by distributions of high monoterpene-containing western redcedar in available plots. Olfaction may play a significant role in both fine and coarse-scale browse behaviors of deer as they employ a risk-averse foraging strategy.

Disease management decision aids, however, commonly are implemented based on hourly weather measurements made from sensors sited at a standard placement of 1.5 m above the ground or are estimated from off-site weather measurements. We investigated temperature measurement errors introduced when sampling interval was increased from 15 to 60 min, and when actual in-canopy conditions were represented by temperature measurements collected by standard-placement sensors (1.5m above the ground, outside the canopy) in each of three crops (grass seed, grape, and hops) and assessed the impact of these errors on outcomes of decision aids for grass stem rust as well as grape and hops powdery mildews. Decreasing time resolution from 15 to 60 min resulted in statistically significant underestimates of daily maximum temperatures and overestimates of daily minimum temperatures that averaged 0.2 to 0.4 degree C. Sensor location (in-canopy versus standard-placement) also had a statistically significant effect on measured temperature, and this effect was significantly less in grape or hops than in the grass seed crop. Effects of these temperature errors on performance of disease management decision aids were affected by magnitude of the errors as well as the type of decision aid. The grape and hops powdery mildew decision aids used rule-based indices, and the relatively small ( plus or minus 0.8 degree C) differences in temperature observed between in-canopy and standard placement sensors in these crops resulted in differences in rule outcomes when actual in-canopy temperatures were near a threshold for declaring that a rule had been met. However, there were only minor differences in the management decision (i.e., fungicide application interval). The decision aid for grass stem rust was a simulation model, for which temperature recording errors associated with location of the weather station resulted in incremental (not threshold) effects on the model of pathogen growth and plant infection probability. Simple algorithms were devised to correct the recorded temperatures or the computed infection probability to produce outcomes similar to those resulting from in-canopy temperature measurements. This study illustrates an example of evaluating (and, if necessary, correcting) temperature measurement errors from weather station sensors not located within the crop canopy, and provides an estimate of uncertainty in temperature measurements associated with location and sampling interval of weather station sensors.

Recently, a disease was observed that produces dark brown to black fissured cankers from 1 to 3 cm long and 1 to 4 cm wide. The infected bark tissue becomes swollen with the middle region 3 to 8 mm thick. Symptoms appear when the trees are approximately 3 years old. As the trees mature, the cankers increase in size and weaken the branches, often resulting in breakage with the weight of the fruit causing substantial plant damage and fruit loss. In August 2010, fissured branch samples of rambutan and pulasan were collected from 6- to 8-year-old trees from the Humid Tropical Demonstrative Agroforestry Center in Honduras, Atlantida, La Masica (15 degree 33'47.4"N, 87 degree 05'2.5"W, elevation 106 m). A fungus associated with the cankers was identified as Dolabra nepheliae. It produces black, stipitate, elongate ascomata, 312 to 482 x 250 to 281 mu m with broadly cylindric, bitunicate asci, 120 to 138 x 11.2 to 15.0 mu m, and filiform, hyaline ascospores, 128 to 135 x 2.8 to 3.2 mu m. Fungi from rambutan and pulasan were isolated on cornmeal agar plus 0.5% dextrose and antibiotics. On potato dextrose agar, the ascospores produced slow-growing colonies, 5 mm per week. In culture, isolates from both hosts produced pycnidia with elongated, slightly to strongly curved or S-shaped, hyaline conidia, 22.8 to 46.4 x 2.8 to 3.7 mu m. This fungus was first reported on rambutan and pulasan from Malaysia (1.4). and later reported on rambutan and litchi in Hawaii and Puerto Rico (3). To our knowledge, this is the first report of D. nepheliae on pulasan and rambutan from Honduras. Specimens have been deposited at the U.S. National Fungus Collections (BPI 882442 on N. lappaceum and BPI 882443 on N. mutabile). Cultures were deposited at the Centraalbureau voor Schimmelcultures (CBS) as CBS 131490 on N. lappaceum and CBS 131491 on N. mutabile. Sequences of the internal transcribed spacer (ITS) region including ITS1, 5.8S, and ITS2 intergenic spacers were deposited in GenBank (Accession No. JQ004281 on N. lappaceum and Accession No. JQ004280 on N. mutabile). A BLAST search and pairwise comparison using the GenBank web server were used to compare ITS sequence data and recovered the following results: (i) CBS 131490 on N. lappaceum is 99% (538 of 544) identical to D. nepheliae CBS 123297 on Litchi chinensis from Puerto Rico: and (ii) CBS 131491 on N. mutabile is 99% (527 of 533) identical to the same strain of D. nepheliae. On the basis of the ITS sequence data, the isolates from Honduras were confirmed as the same species, D. nepheliae from Puerto Rico. Efforts to develop resistant germplasm and management strategies to control this disease have been initiated.

The objective of this study was to characterize races of P. graminis f. sp. tritici present in the Debre Zeit, Ethiopia stem rust nursery. Three races of P. graminis f. sp. tritici were identified from 34 isolates: JRCQC, TRTTF, and TTKSK. Both races JRCQC and TRTTF possess virulence on stem rust resistance genes Sr13 and Sr9e, which may explain why many TTKSK-resistant durum lines tested in Kenya became susceptible in Debre Zeit. The Sr9e-Sr13 virulence combination is of particular concern because these two genes constitute major components of stem rust resistance in North American durum cultivars. In addition to Sr9e and Sr13 virulence, race TRTTF is virulent to at least three stem rust resistance genes that are effective to race TTKSK, including Sr36, SrTmp, and resistance conferred by the 1AL.1RS rye translocation. Race TRTTF is the first known race with virulence to the stem rust resistance carried by the 1AL.1RS translocation, which represents one of the few effective genes against TTKSK in winter wheat cultivars in the United States. Durum entries exhibiting resistant to moderately susceptible infection response at the Debre Zeit nursery in 2009 were evaluated for reaction to races JRCQC, TRTTF, and TTKSK at the seedling stage. In all, 47 entries were resistant to the three races evaluated at the seedling stage, whereas 26 entries exhibited a susceptible reaction. These results suggest the presence of both major and adult plant resistance genes, which would be useful in durum-wheat-breeding programs. A thorough survey of virulence in the population of P. graminis f. sp. tritici in Ethiopia will allow characterization of the geographic distribution of the races identified in the Debre Zeit field nursery.

This field investigation was conducted to evaluate the interactions between spinach genotypes and different BNYVV strains, and to determine whether BNYVV is transmitted through spinach seeds. Eight commercial spinach cultivars were planted in two BNYVV-infested fields and two control fields in Salinas, CA in 2009. Spinach plants in the BNYVV-infested fields showed disease symptoms of yellow-green or light-green vein clearing, mottling, or yellow-green chlorotic lesions on younger leaves as early as 28 days after planting (four- to six-true leaf stage). Leaves may also become stiff, more crinkled, and necrotic. There was an increase of lateral roots and leaf number but a decrease in leaf weight compared to healthy plants. Infected plants often became stunted, deformed, wilted, and dead. Symptomatic leaves and roots from plants with or without leaf symptoms in BNYVV-infested fields all tested positive for BNYVV by enzyme-linked immunosorbent assay. A more aggressive (resistance-breaking) strain of BNYVV led to higher disease incidence in spinach than in the wild type. BNYVV was not transmitted through spinach seeds. There were significant differences in disease development among cultivars, with disease incidence ranging from 8 to 44%, suggesting that genetic improvement of BNYVV resistance through spinach breeding should be feasible.

Rapid detection of this pathogen is crucial in food industries and clinical laboratories to control S.aureus food poisoning and human infections. In this study, Fourier transform infrared spectroscopy equipped with a germanium attenuated total reflection accessory was used as a novel approach to identify S.aureus. A total of 17 reference strains belonging to 4 different species and 84 clinical isolates of Staphylococcus spp. were analyzed. After the cultivation of the strains, spectral collection and data preprocessing, the S.aureus isolates were identified by a two-step discrimination procedure. An internal validation and the related external validation were performed to demonstrate the discriminatory power and the quality of the discrimination models before the discrimination analysis. In the first step, 38 S.aureus isolates were correctly classified and the others were misidentified as Staphylococcus haemolyticus by hierarchical clustering analysis model using the first derivatives from the spectral range between 1,800 and 1,050/cm. In the second step, several classification/discrimination algorithms of soft-independent modeling of class analogy, principal component regression and partial least squares regression (PLSR) were applied to build models for differentiating S.aureus and S.haemolyticus. The results showed that 57 (98.3%) strains and 4 (100%) strains of S.aureus and S.haemolyticus could be correctly identified by PLSR. Fourier transform infrared (FTIR) spectroscopy is a potential method for rapid discrimination, classification and identification of intact microbial cells. In this study, FTIR spectroscopy equipped with a germanium attenuated total reflection accessory, using hierarchical clustering analysis-partial least squares regression discrimination analysis, is a powerful means for routine identification of Staphylococcus aureus.

Traditional and chromatographic protein isotherms of albumin binding on modified cotton fibers are useful in understanding albumin binding to cellulose wound dressings. An important consideration in the design of cellulosic wound dressings is adsorption and accumulation of proteins like albumin at the solid-liquid interface of the biological fluid and wound dressing fiber. To better understand the effect of fiber charge and molecular modifications in cellulose-containing fibers on the binding of serum albumin as observed in protease sequestrant dressings, albumin binding to modified cotton fibers was compared with traditional and chromatographic isotherms. Modified cotton including carboxymethylated, citrate-crosslinked, dialdehyde and phosphorylated cotton, which sequester elastase and collagenase, were compared for their albumin binding isotherms. Albumin isotherms on citrate-cellulose, cross-linked cotton demonstrated a two-fold increased binding affinity over untreated cotton. A comparison of albumin binding between traditional, solution isotherms and chromatographic isotherms on modified cellulose yielded similar equilibrium constants. Application of the binding affinity of albumin obtained in the in vitro protein isotherm to the in vivo wound dressing uptake of the protein is discussed. The chromatographic approach to assessment of albumin isotherms on modified cellulose offers a more rapid approach to evaluating protein binding on modified cellulose over traditional solution approaches.

L.monocytogenes was either inoculated into (IN) the curds before forming the cheese block or onto (ON) slices (52-66g), individually vacuum-packed and stored at 4 and 10C. Growth was monitored for up to 35 days. Gompertz analyses showed small differences in lag time because of temperature, but growth rate and generation time were faster at 10C than at 4C. After 20 days for both the IN and the ON treatments, the maximum population density was 7.80+/-0.17, regardless of the storage temperature. These results indicate that QF manufacture must be conducted using Good Manufacturing Practices and under hygienic conditions, and that the use of antimicrobials and/or postprocessing interventions is necessary to prevent the presence and growth of L.monocytogenes. Queso fresco (QF) is a popular, rennet-set, Hispanic-style fresh cheese made from pasteurized milk known for its crumbly texture and nonmelting properties. However, its high moisture content, near neutral pH and moderate salt content provide the ideal conditions for growth of various spoilage and pathogenic bacteria, notably Listeria monocytogenes. Past studies have examined the growth of L.monocytogenes on QF but were typically conducted using retail cheese of unknown manufacturing, handling and storage procedures. In this study, the growth of L.monocytogenes was monitored in and on QF made according to a commercial procedure used in the U.S.A. These data and a primary model that was created from the data can be used as the basis for food safety assessments and process and formulation improvements, or to monitor the effectiveness of antimicrobials and process interventions in preventing the presence and growth of L.monocytogenes associated with QF.

AN - 1010234455; 22302451 AB - Hexazinone, a triazine herbicide that is often detected as a ground and surface water contaminant, inhibits electron transport in photosynthetic organisms and is toxic to primary producers that serve as the base of the food chain. This laboratory study evaluated the ability of two types of microbial reactors, i.e., a vegetable oil-based nitrogen-limiting biobarrier and an aerobic slow sand filter, as methods for removing hexazinone from simulated groundwater. The N-limiting biobarriers degraded hexazinone, but did so with a 52 week incubation period and a removal efficiency that varied greatly among replicates, with one biobarrier showing a removal efficiency of ~95% and the other an efficiency of ~50%. More consistent degradation was obtained with the aerobic sand biobarriers. Four aerobic biobarriers were evaluated and all behaved in a similar manner degrading hexazinone with removal efficiencies of ~97%; challenging two of the aerobic biobarriers with large amounts of influent hexazinone showed that these barriers are capable of efficiently remediating large amounts (>100 mg L(-1)) of hexazinone at high efficiency. The remediation process was due to biological degradation rather than abiotic processes. The long lag phase observed in both types of reactors suggests that an acclimation process, where microorganisms capable of degrading hexazinone increased in numbers, was required. Also, the isolation of bacteria that show a positive growth response to the presence of hexazinone in their growth media suggests biological degradation.

For the study of interspecific interactions, molecular gut-content analysis enables detection of arthropod predation with minimal disruption of community interactions. Field experiments have demonstrated that standard mass-collection methods, such as sweep netting, vacuum sampling and foliage beating, sometimes lead to contamination of predators with nontarget DNA, thereby compromising resultant gut-content data. We deliberately contaminated immature Coleomegilla maculata and Podisus maculiventris that had been fed larvae of Leptinotarsa decemlineata by topically applying homogenate of the alternate prey Leptinotarsa juncta. We then attempted to remove contaminating DNA by washing in ethanol or bleach. A 40-min wash with end-over-end rotation in 80% EtOH did not reliably reduce external DNA contamination. Identical treatment with 2.5% commercial bleach removed most externally contaminating DNA without affecting the detectability of the target prey DNA in the gut. Use of this bleaching protocol, perhaps with minor modifications tailored to different predator-prey systems, should reliably eliminate external DNA contamination, thereby alleviating concerns about this possible source of cross-contamination for mass-collected arthropod predators destined for molecular gut-content analysis.

To mitigate livestock methane, incentive policies based on producer-level emissions are generally not feasible because of high administrative costs and producer transaction costs. In contrast, incentive policies based on sectoral emissions are likely administratively feasible, even in developing countries. This study uses an economic model of global agriculture to estimate the effects of two sectoral mitigation policies: a carbon tax and an emissions trading scheme based on average national methane emissions per unit of commodity. The analysis shows how the composition and location of livestock production and emissions change in response to the policies. Results illustrate the importance of global mitigation efforts: when policies are limited to Annex 1 countries, increased methane emissions in non-Annex 1 countries offset approximately two-thirds of Annex 1 emissions reductions. While non-Annex 1 countries face substantial disincentives to enacting domestic carbon taxes, developing countries could benefit from participating in a global sectoral emissions trading scheme. We illustrate one scheme in which non-Annex 1 countries collectively earn USD 2.4 billion annually from methane emission permit sales when methane is priced at USD 30/t CO sub(2)-eq.

The samples were evaluated for the incidence of aflatoxigenic strains of Aspergillus flavus. The soil samples collected from Peshawar (100%) and Hazara (66%), and grain samples collected from Swat (64%) and Peshawar (55%) were severely infected with aflatoxigenic strains of A. flavus. The strains isolated from maize kernels of Manyar, Jalala (Swat zone), Palosi and Takkar (Peshawar zone) produced the highest amount of aflatoxin B1 (324 to 514 mu g g super(-1)) and B2 (23 to 486 mu g g super(-1)). Similarly, the strains isolated from soils of Bannu (Peshawar) and Huripur (Hazara) were prominent in B1 (662 to 1323 mu g g super(-1)) and B2 (145 to 826 mu g g super(-1)). Microbial analysis of the surface sterilized grains showed that the strains isolated from Jalala (Swat) and Palosi (Peshawar) samples were high in B1 (62 to 79 mu g g super(-1)) and B2 (21 to 36 mu g g super(-1)). It was concluded, therefore, that A. flavus from soil might contaminate maize crop, but not directly from the same field. The most probable contamination occurred through air borne spores.

AN - 993912799; 22429238 AB - Cultivation of Crotalaria juncea L. (Sunn Hemp cv. 'Tropic Sun') is recommended as a green manure crop in a rotation cycle to improve soil condition, help control erosion, suppress weeds, and reduce soil nematodes. Because C. juncea belongs to a genus that is known for the production of toxic dehydropyrrolizidine alkaloids, extracts of the roots, stems, leaves, and seeds of 'Tropic Sun' were analyzed for their presence using HPLC-ESI/MS. Qualitative analysis identified previously unknown alkaloids as major components along with the expected macrocyclic dehydropyrrolizidine alkaloid diesters, junceine and trichodesmine. The dehydropyrrolizidine alkaloids occurred mainly as the N-oxides in the roots, stems, and, to a lesser extent, leaves, but mainly as the free bases in the seeds. Comprehensive spectrometric and spectroscopic analysis enabled elucidation of the unknown alkaloids as diastereoisomers of isohemijunceine, a monoester of retronecine with an unusual necic acid. The dehydropyrrolizidine alkaloid contents of the roots, stems, and leaves of immature plants were estimated to be 0.05, 0.12, and 0.01% w/w, respectively, whereas seeds were estimated to contain 0.15% w/w.

If the sample is contaminated by more than one strain of the pathogen the relevant strain might be missed. In this study mixed cultures of Salmonella enterica were grown in one set of standard enrichment media to see if culture bias patterns emerged. Nineteen strains representing four serogroups and ten serotypes were compared in four-strain mixtures in Salmonella-only and in cattle fecal culture enrichment backgrounds using Salmonella enrichment media. One or more strain(s) emerged as dominant in each mixture. No serotype was most fit, but strains of serogroups C2 and E were more likely to dominate enrichment culture mixtures than strains of serogroups B or C1. Different versions of Rappaport-Vassiliadis (RV) medium gave different patterns of strain dominance in both Salmonella-only and fecal enrichment culture backgrounds. The fittest strains belonged to serogroups C1, C2, and E, and included strains of S. Infantis, S. Thompson S. Newport, S. 6,8:d:-, and S. Give. Strains of serogroup B, which included serotypes often seen in outbreaks such as S. Typhimurium, S. Saintpaul, and S. Schwarzengrund were less likely to emerge as dominant strains in the mixtures when using standard RV as part of the enrichment. Using a more nutrient-rich version of RV as part of the protocol led to a different pattern of strains emerging, however some were still present in very low numbers in the resulting population. These results indicate that outbreak investigations of food and/or other environmental samples should include multiple enrichment protocols to ensure isolation of target strains of Salmonella.

Liberibacter asiaticus,' an insect-vectored, obligate intracellular bacterium associated with citrus-greening disease, also called "HLB," is a member of the Rhizobiales along with nitrogen-fixing microsymbionts Sinorhizobium meliloti and Bradyrhizobium japonicum, plant pathogen Agrobacterium tumefaciens and facultative intracellular mammalian pathogen Bartonella henselae. Comparative analyses of their circular chromosomes identified 514 orthologous genes shared among all five species. Shared among all five species are 50 identical blocks of microsyntenous orthologous genes (MOGs), containing a total of 283 genes. While retaining highly conserved genomic blocks of microsynteny, divergent evolution, horizontal gene transfer and niche specialization have disrupted macrosynteny among the five circular chromosomes compared. Highly conserved microsyntenous gene clusters help define the Rhizobiales, an order previously defined by 16S RNA gene similarity and herein represented by the three families: Bartonellaceae, Bradyrhizobiaceae and Rhizobiaceae. Genes without orthologs in the other four species help define individual species. The circular chromosomes of each of the five Rhizobiales species examined had genes lacking orthologs in the other four species. For example, 63 proteins are encoded by genes of 'Ca. Liberibacter asiaticus' not shared with other members of the Rhizobiales. Of these 63 proteins, 17 have predicted functions related to DNA replication or RNA transcription, and some of these may have roles related to low genomic GC content. An additional 17 proteins have predicted functions relevant to cellular processes, particularly modifications of the cell surface. Seventeen unshared proteins have specific metabolic functions including a pathway to synthesize cholesterol encoded by a seven-gene operon. The remaining 12 proteins encoded by 'Ca.

AN - 993315700; 21902799 AB - Resveratrol and related stilbenes are thought to play important roles in defence responses in several plant species and have also generated considerable interest as nutraceuticals owing to their diverse health-promoting properties. Pterostilbene, a 3,5-dimethylether derivative of resveratrol, possesses properties similar to its parent compound and, additionally, exhibits significantly higher fungicidal activity in vitro and superior pharmacokinetic properties in vivo. Recombinant enzyme studies carried out using a previously characterized O-methyltransferase sequence from Sorghum bicolor (SbOMT3) demonstrated its ability to catalyse the A ring-specific 3,5-bis-O-methylation of resveratrol, yielding pterostilbene. A binary vector was constructed for the constitutive co-expression of SbOMT3 with a stilbene synthase sequence from peanut (AhSTS3) and used for the generation of stably transformed tobacco and Arabidopsis plants, resulting in the accumulation of pterostilbene in both species. A reduced floral pigmentation phenotype observed in multiple tobacco transformants was further investigated by reversed-phase HPLC analysis, revealing substantial decreases in both dihydroquercetin-derived flavonoids and phenylpropanoid-conjugated polyamines in pterostilbene-producing SbOMT3/AhSTS3 events. These results demonstrate the potential utility of this strategy for the generation of pterostilbene-producing crops and also underscore the need for the development of additional approaches for minimizing concomitant reductions in key phenylpropanoid-derived metabolites.

NuPro registered replaced fish meal at six levels (0, 25, 50, 75, 100 and 125gkg-1 diet). Catfish were sampled for whole-body composition and then challenged with the bacterium Edwardsiella ictaluri. Growth performance was negatively affected (P<0.01) when NuPro registered was added at 125gkg-1 diet. The amount of whole-body fat decreased (P<0.05) when NuPro registered was added at 75gkg-1 or more of the diet. Regardless of the amount of NuPro registered added, survival after challenge with E. ictaluri was similar among treatments. Results indicate that up to 100gkg-1 of NuPro registered can be added without negatively affecting growth performance. The yeast-derived protein source used in this study is a sustainable protein alternative that could be used as a partial replacement for fish meal in juvenile channel catfish diets.

Methods and Results: Swine or cattle were fed the respective growth promotant, manure was collected, and 2-l laboratory methane digesters were established at the various temperatures and sampled over 25 or 28days. After 21days, the concentration of CTC in the 22, 38 and 55 degree C swine digester slurries decreased 7, 80 and 98%, respectively. Coliforms in the 22 degree C digester slurries were still viable after 25days; however, they were not detectable in the 38 and 55 degree C slurries after 3 and 1days, respectively. After 28days, the concentration of MON in the 22, 38 and 55 degree C cattle digester slurries decreased 3, 8 and 27%, respectively. Coliforms in the 22 degree C cattle digester slurries were still viable after 28days; however, they were not detectable in the 38 and 55 degree C slurries after 14 and 1days, respectively. Conclusions: These studies indicate that anaerobic digestion at 38 or 55 degree C may be an effective treatment to reduce coliforms and CTC; however, it is not an effective treatment to reduce MON. Significance and Impact of the Study: More studies are needed to determine which pharmaceuticals are susceptible to degradation by a specific manure treatment to prevent negative environmental consequences.

Penz. & Sacc. in Penz. (CGS) is a facultative parasitic fungus being evaluated as a classical biological control agent of Russian thistle or tumbleweed (Salsola tragus L.). In initial host range determination tests, Henderson's mixed model equations (MME) were used to generate best linear unbiased predictors (BLUPs) of disease severity reaction to CGS among 89 species of plants related to S. tragus. The MME provided: (1) disease assessments for rare and difficult or impossible to grow species, (2) environmentally independent measures of disease severity, (3) measures of disease severity for species versus a sample of material tested in a greenhouse, (4) objective indicators of susceptible and non-susceptible species, (5) a means to objectively compare disease on targets versus non-targets. Of the 89 species evaluated by the MME, eight native N. American species were predicted to be susceptible. As a result of these predictions, these eight species were further evaluated to determine the amount of actual damage caused by CGS. This was done by comparing root and shoot areas and weights between non-inoculated plants and plants inoculated with CGS. Results showed that several of the species exhibited some minor reduction in root weight and root area, but none of the species had any damage to above-ground plant parts. This supports the BLUP output in the initial host range determination tests. As a result of both analyses, there is no evidence that CGS would cause any non-target effects in nature.

However, correcting water flow patterns alone will not restore the associated plant communities due to habitat-transforming effects of invasive species, in particular the Australian wetland tree Melaleuca quinquenervia (Cav.) S. T. Blake (Myrtales, Myrtaceae), which has invaded vast areas and transformed sawgrass marshes into dense, biologically impoverished, structurally altered forest habitats. To address this threat, an invasive species reduction program was launched that combined mechanical removal and herbicidal control to remove mature trees with the release of specialized insects to suppress seed production and lower seedling survival. Melaleuca has now been removed from most public lands while biological control has limited its ability to regenerate and reinvade from nearby infestations often located on unmanaged privately held lands. This case illustrates how restoration of highly modified ecosystems may require both restoration of physical conditions (water flow), and suppression of high impact or transformative invaders, showing well the need to integrate biological control into conservation biology.

The spatially compact nature of Micronesian mangroves results in model ecosystems to test these ideas. Tidal creek nekton assemblages were compared among mangrove forests impacted by Typhoon Sudal and differing in stand structure. Structurally complex Rhizophora spp. stands were predicted to support higher densities and different communities of nekton and to provide greater protection from typhoons compared to less complex Sonneratia alba/Bruguiera gymnorrhiza stands. Lift net data revealed that structural complexity did not support greater nekton densities, but did support significantly different nekton assemblages. The cardinalfish Apogon ceramensis and goby Oxyurichthys lonchotus had significantly higher densities in S. alba/B. gymnorrhiza mangrove creeks, whereas the silverside Atherinomorus lacunosus and diogenid crabs had significantly higher densities in Rhizophora spp. creeks. Similar nekton densities 17 and 4 months after the typhoon in Rhizophora spp. creeks provided indirect evidence that structural complexity increased protection for resident nekton from disturbances. Findings indicate that studies of structural complexity and nekton densities may be better served when individual species are compared and that diverse mangrove tree assemblages will support diverse nekton assemblages that may be more resilient to disturbance.

A weed biological control program targeting Melaleuca quinquenervia in Florida, USA has resulted in the release and establishment of Oxyops vitiosa and Boreioglycaspis melaleucae. An international survey of M. quinquenervia populations in 13 other states or countries where the insects have not been intentionally introduced was initiated to monitor the long range dispersal of O. vitiosa and B. melaleucae beyond the herbivores' intended geographic range (Florida). Surveys in 2006 resulted in the discovery of B. melaleucae within the canopies of several M. quinquenervia trees near San Juan, Puerto Rico. In 2007, O. vitiosa was observed on the island of New Providence in the Bahamas but neither herbivore was detected on nearby Grand Bahama or Andros islands. In 2009, B. melaleucae was observed attacking M. quinquenervia trees in Los Angeles, California (USA). The herbivores have not been detected on other surveyed M. quinquenervia populations in Cuba, Jamaica, Texas (USA), Costa Rica, Brazil, Hawaii (USA) or South Africa. There is no evidence to suggest that herbivore colonization of New Providence, Puerto Rico, or California was influenced by linear distance between Florida and the recipient M. quinquenervia stand. While the dispersal pathway(s) remains unknown, biological control agents were detected from 200 to >3500 km from their original release location (Florida) and at locations that have strong links via tourism and trade as indicated by the number of airline flights connecting south Florida with colonized tree populations. Implications of this unintended spread are discussed in relation to permeability of biogeographical barriers and risk assessment of biological control agents.

Results from two years of field surveys showed that several hymenopteran parasitoids have become associated with EAB in Michigan. Among these parasitoids, the gregarious species T. planipennisi was the most abundant, accounting for 93% of all parasitoid individuals collected in 2009 (immediately after field release) and 58% in 2010 (a year later after field releases). Low levels (1-5%) of parasitism of EAB larvae by T. planipennisi were consistently detected at survey sites in both years. Separately, the abundance of the native parasitoid, Atanycolus spp., increased sharply, resulting in an average parasitism rate of EAB larvae from <0.5% in 2009 to 19% in 2010. Other parasitoids such as Phasgonophora sulcata Westwood, Spathius spp., Balcha indica Mani & Kaul, Eupelmus sp., and Eurytomus sp. were much less abundant than T. planipennisi and Atanycolus spp., and each caused <1% parasitism. Besides hymenopteran parasitoids, woodpeckers consumed 32-42% of the immature EAB stages present at our study sites, while undetermined biotic factors (such as microbial disease and host tree resistance) caused 10-22% mortality of observed EAB larvae. Relevance of these findings to the potential for biological control of EAB in the invaded areas of North America is discussed.

Potential for biological control of the goldspotted oak borer, Agrilus auroguttatus AN - 954641507; 16423140 AB - The goldspotted oak borer (GSOB), Agrilus auroguttatus Schaeffer (Coleoptera: Buprestidae), is an introduced and aggressive phloem/wood borer infesting native oaks in southern California. Elevated levels of oak mortality have occurred continually for the last nine years on three oak species in San Diego Co., California, USA. Biological control is being assessed as an option for long-term and widespread management of the invasive population of GSOB. Foreign exploration in the native ranges of GSOB and a related sibling species (Agrilus coxalis Waterhouse) was conducted to determine life history information, to assess the natural enemy complex, and to collect specimens for molecular analyses that could help to identify the area of origin of California's introduced population. Two species of parasitoids, Calosota elongata Gibson (Eupelmidae) and Atanycolus simplex Cresson (Braconidae), were discovered with GSOB populations in Arizona and California. No insect natural enemies were found with populations of A. coxalis in southern Mexico. However, Quercus conzatti Trel. and Quercus peduncularis Nee in Oaxaca and Chiapas, respectively, were recorded as the first known hosts of A. coxalis. A comparative analysis of our understanding of the natural enemy complexes for other pestiferous Agrilus with that of GSOB suggests that more effort should be directed at uncovering potential egg parasitoids and microbial pathogens of GSOB. Analyses of mitochondrial and nuclear ribosomal DNA (rDNA) revealed that the California population of GSOB was more similar to the Arizona population. Specimens of A. coxalis from southern Mexico were confirmed as a separate species. Additional surveys and sampling are needed across the complete native range of the GSOB species complex to develop a comprehensive inventory of parasitoid species that could be considered for use in a classical biological control program in California and to delineate the area of origin of California's population.

As part of a collaborative effort to employ molecular genetics technologies in striped bass breeding programs, we previously developed nearly 500 microsatellite markers. The objectives of this study were to construct a microsatellite linkage map of striped bass and to examine conserved synteny between striped bass and three-spined stickleback (Gasterosteus aculeatus). Of 480 microsatellite markers screened for polymorphism, 289 informative markers were identified and used to genotype two half-sib mapping families. Twenty-six linkage groups were assembled, and only two markers remain unlinked. The sex-averaged map spans 1,623.8 cM with an average marker density of 5.78 cM per marker. Among 287 striped bass microsatellite markers assigned to linkage groups, 169 (58.9%) showed homology to sequences on stickleback chromosomes or scaffolds. Comparison between the stickleback genome and the striped bass linkage map revealed conserved synteny between these two species. This is the first linkage map for any of the Morone species. This map will be useful for molecular mapping and marker-assisted selection of genes of interest in striped bass breeding programs. The conserved synteny between striped bass and stickleback will facilitate fine mapping of genome regions of interest and will serve as a new resource for comparative mapping with other Perciform fishes such as European sea bass (Dicentrarchus labrax), gilthead sea bream (Sparus aurata), and tilapia (Oreochromis ssp.).

We applied a vacuum to ceramic cups in pots filled with soil to reduce the soil water matric potential to -0.10 MPa. This system resulted in uniform soil water content throughout the pot, and was used to maintain a constant mild stress for seven days. In cotton, the soil water stress treatment reduced stomatal conductance at both 380 and 560 mu mol mol-1 CO2, but the reduction was relatively smaller at the higher CO2. No reduction of photosynthesis measured under the daytime growth conditions occurred at elevated CO2 in stressed cotton plants, while photosynthesis was reduced by the stress in the lower CO2 treatment. The soil water stress treatment reduced the leaf area and biomass of cotton at the lower, but not at the higher CO2. In soybean, the soil water stress treatment reduced stomatal conductance, photosynthesis and growth at both CO2 levels, but the effect of water stress was not less at elevated than ambient CO2. In neither species nor CO2 level did the soil water stress treatment cause a detectable change in daytime leaf water potential. In both species, the stomatal closure with the soil water stress may have resulted from the lower soil to leaf hydraulic conductivity. The failure of high CO2 to protect soybean growth from the soil water stress might be related to the lower hydraulic conductivity of stressed soybeans grown at elevated compared with ambient CO2.

Gossypol is a naturally occurring polyphenolic aldehyde with antioxidant properties isolated from cottonseed that is toxic to humans and animals. At treatment levels of 250 and 500 ppm, gossypol exhibited statistically significant improvements in the induction periods (IPs; EN 14112) of SME, WCME and MO. Efficacy was most pronounced in SME, which was due to its higher concentration of endogenous tocopherols (757 ppm) versus WCME (60 ppm) and MO (0 ppm). A comparison of antioxidant efficacy was made with butylated hydroxytoluene (BHT) and I super(3)-tocopherol. For FAMEs with low concentrations of endogenous tocopherols (WCME and MO), I super(3)-tocopherol exhibited the greatest efficacy, although treatments employing BHT and gossypol also yielded statistically significant improvements to oxidative stability. In summary, gossypol was effective as an exogenous antioxidant for FAMEs investigated herein. In particular, FAMEs containing a comparatively high percentage of endogenous tocopherols were especially suited to gossypol as an antioxidant additive.

However, little is known about how maintaining habitat connectivity for one species or species group may also act as an umbrella for other species. We evaluated the degree to which predicted connected habitat for each of 144 different hypothetical organisms expressing range of dispersal abilities and ecological responses to elevation, roads and land cover function as an indicators of connected habitat for the others in the U.S. Northern Rocky Mountains. We used resistant kernel modeling to map the extent of the study area predicted to be connected by dispersal for each species. At relatively large dispersal abilities there was extensive overlap between connected habitat for most organisms and much of the study area is predicted to provide connected habitat for all hypothetical organisms simultaneously. In contrast, at low to medium dispersal abilities there was much less intersection of habitat connected by dispersal. We found that habitat specialists with limited dispersal ability are weak indicators of others, and likewise are weakly indicated by others. We evaluated the effectiveness of three carnivores as connectivity umbrellas for many species. All three carnivore species performed significantly worse as connectivity umbrellas than the average across the simulated species. These species are associated with high elevation forested habitats. It is the low elevation and non-forest habitats that are most at risk of habitat loss and fragmentation in the study area, suggesting that a carnivore umbrella may miss many species most at risk.

An analysis of 1549 forested plots within a 14.5 million ha region of southeast Alaska provided strong indications that climate currently limits hemlock dwarf mistletoe (Arceuthobium tsugense (Rosendahl) G.N. Jones) to a subset of the range of its primary tree host, western hemlock (Tsuga heterophylla (Raf.) Sarg.), with infection varying from a high of 20% of trees at sea level to only 5% by 200 m elevation. Three types of modeling approaches (logistic, most similar neighbors, and random forests) were tested for the ability to simultaneously predict abundance and distribution of host and pathogen as a function of climate variables. Current distribution was explained well by logistic models using growing degree-days, indirect and direct solar radiation, rainfall, snowfall, slope, and minimum temperatures, although accuracy for predicting A. tsugense presence at a particular location was only 38%. For future climate scenarios (A1B, A2, and B1), projected increases for A. tsugense habitat over a century ranged from a low of 374% to a high of 757%, with differences between modeling approaches contributing more to uncertainty than differences between climate scenarios.Original Abstract: Le faux-gui (Arceuthobium species) influence plusieurs processus dans les ecosystemes forestiers mais peu d'etudes ont porte sur sa repartition en lien avec le climat. Une analyse de 1549 places echantillons boisees a l'interieur d'une region de 14,5 millions d'hectares dans le sud-est de l'Alaska a clairement montre que le climat limite presentement le faux-gui de la pruche (Arceuthobium tsugense (Rosendahl) G.N. Jones) a un sous-ensemble de l'aire de repartition de son hote principal, pruche de l'Ouest (Tsuga heterophylla (Raf.) Sarg.), avec un taux d'infection qui varie d'un maximum de 20% des arbres au niveau de la mer a seulement 5% vers 200 m d'altitude. Trois types de methodes de modelisation (logistique, voisins les plus similaires et forets aleatoires) ont ete testees pour leur capacite a predire simultanement l'abondance et la repartition de l'hote et du pathogene en fonction des variables climatiques. La repartition actuelle est bien expliquee par des modeles logistiques utilisant les degres-jours de croissance, le rayonnement solaire direct et indirect, la pluie, les chutes de neige, la pente et les temperatures minimum, mais la precision pour predire la presence d'A. tsugense a un endroit donne est de seulement 38%. Dans le cas des scenarios climatiques futurs (A1B, A2 et B1), l'elargissement prevu de l'habitat d'A. tsugense sur une periode de cent ans varie d'un minimum de 374% a un maximum de 757%, les differences entre les methodes de modelisation contribuant davantage a l'incertitude que les differences entre les scenarios climatiques.

The treatments included stump removal and cultivation (CULT), a one-time application of fertilizer combined with stump removal and cultivation (CULT+F), and a control (CON). After 49 years, pine species had no significant effect on any soil physical or chemical parameter examined, despite species differences in basal area. CULT exhibited significantly higher soil bulk density and lower soil C and soil N than CON and CULT+F in the upper 10 cm of soil. Stump removal is not a common practice in southern pine silviculture today; however, as demand for bioenergy fuels or feedstocks increases, more complete biomass utilization will be considered. Residual stumps play an important role in soil nutrient and C retention in pine plantations. Our results show that stump removal can lead to reduced soil C (-21%) and soil N (-35%) compared with controls, although it is possible to mitigate nutrient losses on poor sites with fertilization.Original Abstract: Dans le but de mieux comprendre les effets a long terme du choix des especes et des pratiques d'amenagement forestier sur la qualite du sol et la retention du C, nous avons analyse des echantillons de sol provenant de plantations experimentales de pin a encens (Pinus taeda L.), de pin des marais (Pinus palustris Mill.) et de pin d'Elliott (Pinus elliottii Engelm.) soumises a differentes intensites d'amenagement au Mississippi. Les traitements incluaient l'enlevement des souches et des pratiques culturales (CULT), une application unique de fertilisant combinee a l'enlevement des souches et a des pratiques culturales (CULT+F) et un traitement temoin (CON). Apres 49 ans, les especes de pin n'avaient pas d'effet significatif sur aucun des parametres physiques ou chimiques du sol qui ont ete etudies malgre les differences de surface terriere entre les especes. Dans les premiers 10 cm de sol, la densite apparente du sol etait plus grande et la teneur en C et N du sol etait plus faible dans le traitement CULT que dans les traitements CON et CULT+F. L'enlevement des souches n'est pas une pratique courante de la sylviculture actuelle des pins du sud. Cependant, a mesure que la demande pour la biodiversite et les matieres premieres augmente, une utilisation plus complete de la biomasse sera envisagee. Les souches residuelles jouent un role important dans la retention de C et des nutriments dans le sol des plantations de pin. Nos resultats montrent que l'enlevement des souches peut entrainer une diminution de C (-21%) et de N (-35%) dans le sol comparativement au traitement temoin bien qu'il soit possible d'attenuer les pertes de nutriments dans les stations pauvres par la fertilisation.

Dying stands were dense (mean basal area 47.5 m super(2) /ha), young (mean 176 years), and even-age; mean stand mortality was 70%. Stands were at low elevations (mean 2993 m), on northerly aspects, and experienced warmer, drier climates relative to the regional species distribution. White pine blister rust was not observed; mountain pine beetle infestations were extensive. Ring widths were negatively correlated with climatic water deficit and positively correlated with water-year precipitation. Although trees that survived had greater growth during the 20th century than trees that died, in the 19th century trees that eventually died grew better than trees that survived, suggesting selection for genetic adaptation to current climates as a result of differential tree mortality. Air surveys (2006-2010) in the Sierra Nevada, Mt. Shasta, and Warner Mountains showed similar trends to the intensive studies. Observed mortality from air surveys was highest in the Warner Mountains (38%) and lowest in the Sierra Nevada (5%); northern aspects at lower elevations within each mountain region had the highest probabilities of mortality and dying stands had higher climatic water deficit. Scenarios for the future of whitebark pine in California are discussed.Original Abstract: Une importante vague de mortalite a frappe le pin a ecorce blanche (Pinus albicaulis Engelm.) dans les regions subalpines de l'est de la Californie de 2007 a 2010. Les peuplements touches par la mortalite etaient denses (surface terriere moyenne de 47,5 m super(2) /ha), jeunes (age moyen de 176 ans) et equiennes; le taux moyen de mortalite etait de 70%. Les peuplements etaient situes a faible altitude (moyenne de 2993 m), exposes au nord et soumis a un climat plus chaud et plus sec comparativement a la repartition regionale de l'espece. La rouille vesiculeuse du pin blanc n'a pas ete observee mais les infestations du dendroctone du pin ponderosa etaient tres repandues. La largeur des cernes annuels etait negativement correlee au deficit hydrique climatique et positivement reliee a la precipitation liquide annuelle. Bien que les arbres qui ont survecu aient eu une meilleure croissance durant le 20 super(e) siecle que les arbres qui sont morts, au 19 super(e) siecle les arbres qui ont fini par mourir avaient une meilleure croissance que les arbres qui ont survecu, un indice de selection pour une adaptation genetique au climat actuel due a differents taux de mortalite des arbres. Des inventaires aeriens (2006-2010) dans la Sierra Nevada, le mont Shasta et les monts Warner ont revele des tendances semblables a celles qui ont ete observees dans les etudes intensives. La mortalite observee lors des inventaires aeriens etait la plus forte dans les monts Warner (38%) et la plus faible dans la Sierra Nevada (5%); dans chaque region montagneuse, les probabilites de mortalite etaient les plus fortes a faible altitude sur les versants nord et les peuplements touches par la mortalite avaient un deficit hydrique climatique plus eleve.

We tested these hypotheses by evaluating the effect of forest liming and deer exclosure fencing on northern red oak (Quercus rubra L.) seedling growth and nutrition in five oak shelterwood stands in Pennsylvania over 6 years. In each stand, four planting plots were located inside a 2.4 m high woven wire fence and another four were established outside the fence. About 225 northern red oak acorns were planted in each plot in spring 2004. Dolomitic limestone was applied to randomly selected plots at rates of 0, 4.5, 9.0, and 13.5 Mg.ha super(-1) during May 2004. There were no statistically significant (P less than or equal to 0.05) growth responses to lime applications. The only significant growth responses resulted from the fence versus no-fence treatment. A significant (P < 0.003) fence year interaction for seedling height and root collar diameter indicates differential impacts of deer browsing. By 2009, seedlings inside fences averaged 32 cm tall, while seedlings outside the fences averaged 17 cm. Similarly, root collar diameter averaged 6.6 mm outside the fences and 9.1 mm inside fences.Original Abstract: En Pennsylvanie, deux hypotheses s'affrontent pour expliquer le probleme chronique de regeneration du chene (Quercus spp.) : le broutement excessif du chevreuil et l'epuisement des cations du sol. Nous avons teste ces hypotheses en evaluant l'effet apres six ans du chaulage en foret et de l'utilisation de clotures pour exclure le chevreuil sur la nutrition et la croissance de semis de chene rouge (Quercus rubra L.) dans cinq peuplements soumis a une coupe progressive en Pennsylvanie. Dans chaque peuplement, quatre parcelles de plantation etaient situees a l'interieur d'une cloture grillagee de 2,4 m de haut et quatre autres etaient etablies a l'exterieur de la cloture. Environ 225 glands de chene rouge ont ete plantes dans chaque parcelle au printemps 2004. De la chaux dolomitique a ete appliquee dans des parcelles choisies au hasard a des taux de 0, 4,5, 9,0 et 13,5 Mg.ha super(-1) durant le mois de mai 2004. Les applications de chaux n'ont eu aucun effet significatif (P less than or equal to 0,05) sur la croissance. La seule reaction significative de la croissance etait associee au traitement d'exclusion. Une interaction significative (P < 0,003) entre le traitement d'exclusion et l'annee dans le cas du diametre au collet et de la hauteur des semis indique que l'impact du broutement des chevreuils varie. En 2009, les semis avaient une hauteur moyenne de 32 cm a l'interieur des exclos tandis qu'ils n'avaient en moyenne que 17 cm a l'exterieur. De meme, le diametre au collet etait en moyenne de 6,6 mm a l'exterieur des exclos et de 9,1 mm a l'interieur.

Decline in the Eastern United States AN - 1464506130; 17637089 AB - Cornus florida L. is one of the most numerous tree species in the Eastern United States (US). Multiple studies have reported localized declines in C. florida populations following the intro-duction of the destructive fungus Discula destructiva Redlin (dogwood anthracnose), but few, if any, have documented changes in C. florida populations across the species' entire natural range. Thus, a current assessment of the C. florida population in the Eastern US and implications for future sustainability is warranted. Our study's goal was to present C. florida population estimates across the natural range of the species (Little, 1971) in the Eastern US for two periods based on state-level forest land inventories conducted by the US Department of Agriculture Forest Service, Forest Inventory and Analysis (FIA) program. Rangewide, C. florida populations declined by approximately 49% over the time periods studied. At the State level, population declines occurred in 17 out of 30 states and biomass declines occurred in 20 out of 30 states studied. While declines were widespread in the substate units surrounding the Appalachians, the largest declines appeared to be centered within the Appalachian ecoregion.

Type 2 diabetes increases risk of chronic disease. The recommendations are for youth to attain at least 60 minutes of daily physical activity (PA). Fewer than 20% achieve this goal. This study examines differences between blood glucose control and PA in youth with type 2 diabetes. Methods. A1c levels and PA were tested in youth 9 to 17 years old with newly diagnosed type 2 diabetes during clinic visits. Average daily minutes of moderate to vigorous physical activity (MVPA) was calculated. Differences in MVPA were investigated. Results. Slightly more than half of youth had well-controlled diabetes. All engaged in less PA than recommended. Youth with well-controlled diabetes engaged in slightly less MVPA than those whose diabetes was not in control. There were no significant differences in minutes of MVPA by gender, race, or diabetes control. Conclusions. It is necessary to identify ways to increase PA among youth with type 2 diabetes.

Accordingly, strategies to improve compatibility between wind energy development and conservation of bat populations are needed. We combined results of continuous echolocation and meteorological monitoring at multiple stations to model conditions that explained presence of LowF bats at a wind energy facility in southern California. We used a site occupancy approach to model nightly LowF bat presence while accounting for variation in detection probability among echolocation detectors and heights. However, we transposed the spatial and temporal axes of the conventional detection history matrix such that occupancy represented proportion of nights, rather than monitoring points, on which LowF bats were detected. Detectors at 22m and 52m above ground had greater detection probabilities for LowF bats than detectors at 2m above ground. Occupancy of LowF bats was associated with lower nightly wind speeds and higher nightly temperatures, mirroring results from other wind energy facilities. Nevertheless, we found that building separate models for each season and considering solutions with multiple covariates resulted in better fitting models. We suggest that use of multiple environmental variables to predict bat presence could improve efficiency of turbine operational mitigations (e.g., changes to cut-in speeds) over those based solely on wind speed. Increased mitigation efficiencies could lead to greater use of mitigations at wind energy facilities with benefits to bat populations. [copy 2011 The Wildlife Society.

We conducted a study during 2005-2007 to determine if Canada geese exhibit a feeding preference among various commercially available turfgrasses. Behavioral responses of captive geese to 9 turfgrasses, bare ground, and litter were observed over 6 4-week trials during July-September following the installation of selected turfgrasses into experimental arenas. Captive geese preferred to forage on Kentucky bluegrass, creeping bentgrass, and fine fescue sods compared to centipedegrass, St. Augustinegrass, and zoysiagrass. Forage qualities and macronutrient levels varied among the turfgrasses and might explain the foraging preferences geese exhibited during this study. Canada goose feeding rate was positively correlated with crude protein, nitrogen content, and calcium, but negatively correlated with acid detergent fiber content, within various turfgrasses. Our findings suggest careful selection of turfgrasses could be an effective method for reducing Canada goose conflicts in urban and suburban areas.

Thus, identification and protection of important winter habitats is a conservation priority. However, not all sagebrush may be alike. More information is needed regarding sage-grouse sagebrush winter dietary preferences for application to management. The objective of our research was to determine if chemical analysis of fecal pellets could be used to characterize winter sage-grouse diets as a substitute for more invasive methods. We collected and analyzed fecal pellets and sagebrush samples from 29 different sage-grouse flock locations in northwestern and southcentral Utah. Using gas chromatography, we were able to identify crude terpene profiles that were unique to Wyoming sagebrush (A. tridentata wyomingensis) and black sagebrush (A. nova). We subsequently used the profiles to determine sagebrush composition of sage-grouse fecal pellets, thus reflecting sage-grouse winter diets. This technique provides managers with a tool to determine which species or subspecies of sagebrush may be important in the winter diets of sage-grouse populations. [copy 2011 The Wildlife Society.

Historically up to 95% of nests were predated, primarily by raccoons Procyon lotor and, more recently, armadillos Dasypus novemcinctus. Predator control was identified as the most important conservation tool for marine turtle reproduction. Predator management by refuge staff as ancillary duties typically only held predation levels to c. 50%. However, when experts in predator control were employed predation was substantially reduced. An extraordinary opportunity to evaluate the biological and economic benefits of this management approach occurred in 2008, a year with exceptionally heavy nesting. Loggerhead turtle Caretta caretta nesting resurged, green Chelonia mydas and leatherback Dermochelys coriacea turtles nested in record numbers, producing twice or more than their median number of nests, and the first Kemp's ridley Lepidochelys kempii nest was observed. Overall predation was 14.7%, resulting in an estimated > 128,000 additional hatchlings emerging compared to estimates had no predator management been in place and historical predation rates occurred, and > 56,000 hatchlings more than expected had predator management been conducted as ancillary duties rather than by experts. The USD 12,000 investment for expert predator management equated to only USD 0.09 spent for each additional hatchling produced compared to the scenario of no predator control and only USD 0.21 compared to the scenario of predator control as ancillary duties.

Methods: Adult and larval A. diaperinus were exposed to two concentrations of a fluorescently labeled Salmonella enterlca for 15, 30, and 60mln time periods then externally disinfected to evaluate internal transfer of Salmonella. The insects were monitored every 30min over 4h and evacuated frass (feces) processed for the marker Salmonella. The minimum time monitored was 45 min (15 exposure+30min time point), and the maximum was 5h (60 exposure+4h time point). Results: Adults treated with 10 super(6) or 10 super(8) colony-forming units (cfu)/mL, which produced Salmonella positive frass within the 5h experimental time, displayed a mean gut transit time of 144.4min (range 90-270min) and 186.3min (range 120-300min), respectively. Larvae treated with 10 super(6) or 10 super(8) cfu/mL displayed a mean gut transit time of 172.5min (range 120-300min) and 131.7min (range 60-300min), respectively. Significance and Impact of Study: Understanding the sources and contribution of reservoir populations of pathogens in poultry production operations is important for development of biosecurity measures to mitigate their transfer. A. diaperinus are prevalent in production operations and difficult to suppress. Management standards accept the reutilization of litter in which insects survive between flock rotations. Removing litter and spreading it onto nearby fields results in the inadvertent dispersal of beetles. Few studies demonstrating the specific bacterial dispersal capacities of these insects have been performed. This study determined that Salmonella acquired internally, commonly transits the gut, allowed the insect to disperse viable pathogenic bacteria within 2-3h.

Choice oviposition experiments were conducted under laboratory conditions to help assess host-plant specificity of the insect. Mean oviposition rates were highest on C. solstitialis (66% of eggs, on a per replicate basis) followed by Centaurea cyanus (bachelor's button 22%), Centaurea melitensis (6%), Centaurea americana (1%), Saussurea americana (3%) and Carthamus tinctorius (safflower 2%). Adult feeding damage followed a similar pattern; however, there was less oviposition relative to the amount of adult feeding on each of the non-target species than on the target host plant, C. solstitialis. Thirteen safflower varieties were tested, and oviposition occurred on eight of them, at low rates. Adult feeding occurred on all safflower varieties tested, although at rates much lower than on yellow starthistle. The results were intermediate between those of previously reported no-choice laboratory and open field experiments. Overall, the combined results support the hypothesis that C. basicorne is not likely to attack any of the non-target plant species tested here except possibly C. cyanus and C. melitensis, which are both invasive alien plants.

The authors used maximum and zero N yields from selected long-term wheat and maize studies to support their conclusion. Yields from plots receiving intermediate N rates in the maize study indicated a probable dependence between grain yield and yield response index, which is contrary to the authors' conclusions. Data from a more recent, long-term irrigated maize study on a similar soil type were used to illustrate that grain yield and yield response index are definitely dependent on each other and further that the in-season sensor-based sufficiency index is highly correlated with relative yield. The implication is that a yield component, as such, does not necessarily need to be included in development of an in-season N recommendation algorithm.

One of the key missions of ARS is to provide, through scientific research, the means to ensure that the food supply is safe and secure for consumers and that food and feed meet foreign and domestic regulatory requirements. Food safety research seeks ways to assess, control or eliminate potentially harmful food contaminants, including both introduced and naturally occurring pathogenic bacteria, viruses and parasites, toxins and non-biological-based chemical contaminants, mycotoxins and plant toxins. Food safety is a global issue; thus, the research program involves both national and international collaborations through formal and informal partnerships. To meet those responsibilities, ARS has engaged more than 180 Ph.D. research scientists in 25 laboratories to work on 62 research projects. Using the involvement in post-harvest food safety research of an Eastern Regional Research Center laboratory in the North Atlantic Area of ARS as an example, I will describe the processes and procedures for project development, research accountability, and technology transfer to stakeholders. In addition, specific examples on significant research accomplishments in pathogen detection involving collaboration with domestic and international entities will also be described.

Epidemiologic and clinical studies suggest that healthy eating, physical activity, and BW control are the main driving forces to reduce diabetes risk. Owing to their low available carbohydrate content, favorable fat and protein profile as well as phytonutrient content, nut consumption has been associated with a reduced risk of development and management of diabetes. Nuts, by virtue of its cardioprotective actions, have also been shown to reduce biomarkers of risk factors for diabetic complications. Although more studies are warranted, the emerging picture is that nut consumption beneficially influences diabetes risk and management beyond blood glucose control.

In this article we use an equilibrium displacement model to estimate and compare the economic welfare effects from a range of hypothetical farm commodity and retail food policies as alternative mechanisms for encouraging consumption of healthy food or discouraging consumption of unhealthy food, or both. We find that, compared with retail taxes on fat, sugar, or all food, or subsidies on fruits and vegetables at the farm or retail levels, a tax on calories would be the most efficient obesity policy. A tax on calories would have the lowest deadweight loss per pound of fat reduction in average adult weight, and would yield a net social gain once the impact on public health care expenditures is considered.

A differential approach to expected utility theory and firm demand is used to derive a model comparable to more popular demand systems such as the Rotterdam and AIDS models. The model is used in estimating carnation demand in the United Kingdom. Results show that while total carnation imports, expected prices and seasonality are important determinants of import demand by source, there is significant information loss when price risk is not considered.

(blackbrush) is a dominant xerophytic shrub species in the ecotone between the warm and cold deserts of interior western North America. Amplified fragment length polymorphisms (AFLPs) were used to survey genetic diversity and population genetic structure at 14 collection sites across the species range. Analysis revealed significant population differentiation (F sub(ST) = 0.103, p < 0.0001) and reasonably high levels of genetic diversity (expected heterozygosity; H sub(E) = 0.26), a surprising result for a putative paleoendemic species. Model-based Bayesian clustering, principal coordinates analysis, and neighbor-joining analysis all produced support for the existence of two metapopulations, the first centered on the Mojave Desert and the second on the Colorado Plateau. These genetic data, coupled with information from Late Pleistocene and Holocene packrat (genus Neotoma Say and Ord, 1825) middens, illustrate a demographic history in which eastern and western distributions were disjunct during the Last Glacial Maximum and remained so through the Holocene, forming the present-day metapopulations in the Mojave Desert and Colorado Plateau. This strong regional genetic differentiation has implications for population persistence and migration in response to future climate change, as well as for shrubland restoration following anthropogenic disturbances such as annual grass invasion and wildfire.Original Abstract: Coleogyne ramosissima Torr. (blackbrush) constitue une espece arbustive xerophyte de l'ecotone entre les deserts chauds et froids de l'interieur de l'ouest Nord-Americain. Les auteurs ont utilise les polymorphismes de la longueur des fragments amplifies (PFLAs) pour examiner la diversite genetique et la structure genetique des populations sur 14 sites de recolte distribues sur l'ensemble de l'aire de l'espece. Les analyses revelent une differenciation significative des populations (F sub(ST) = 0,103, p < 0,0001) ainsi que des degres relativement eleves de diversite genetique (heterozygosie attendue; H sub(E) = 0,26), un resultat surprenant pour une espece presumee paleoendemique. Une modelisation basee sur le regroupement bayesien, l'analyse des coordonnees principales et l'analyse des liaisons entre voisins (neighbor-joining analysis), toutes supportent l'existence de deux metapopulations, la premiere centree sur le Desert Mojave et la seconde sur le Plateau du Colorado. Ces donnees genetiques, couplees avec l'information provenant des monticules de detritus de rats du genre Neotoma Say and Ord, 1825, illustrent une histoire demographique dans laquelle les distributions orientales et occidentales se sont disjointes au cours du maximum de la derniere glaciation, pour demeurer telles quelles tout au long de l'Holocene, formant les metapopulations du Desert Mojave et du Plateau du Colorado. Cette forte differenciation genetique regionale a des implications pour la persistance des populations et leur migration en reaction au changement climatique future, ainsi que pour la restauration des arbustaies, suite aux perturbations anthropiques comme l'invasion par des graminees annuelles et les incendies.

We determined whether phenotypic plasticity and genetic changes in the mean phenotype could affect the adaptation of flowering time to changes in the environment resulting from global warming in a montane plant species, Aquilegia coerulea James. We collected seeds from 17 plants from each of three natural populations. For each of these 51 families, we assigned 3-4 individuals to each of four water and temperature treatments. We observed phenotypic plasticity in flowering time in response to both temperature and water availability but no genetic variance or genetic differentiation in phenotypic plasticity. These results indicate that phenotypic plasticity could provide a quick response to environmental changes but provides little evolutionary potential. In contrast to phenotypic plasticity in flowering time, the mean flowering time did vary among families and among populations, suggesting a genetic basis to flowering time and adaptation in the different populations. The most likely scenario for the adaptation of this plant species to climate change is a rapid response via phenotypic plasticity followed by selection and micro-evolutionary changes in the mean phenotype.Original Abstract: Dans les habitats de haute altitude, une augmentation des temperatures et de plus fortes precipitations sous forme de pluie representent les changements climatiques typiques associes au rechauffement global. Les auteurs ont verifie l'hypothese suggerant que la plasticite phenotypique et les modifications genetiques du phenotype moyen peuvent affecter l'adaptation de la periode de floraison aux changements de l'environnement provenant du rechauffement global, chez une espece de plante montagnarde, l'Aquilegia coerulea James. Ils ont recolte des graines sur 17 plantes dans chacune de trois populations naturelles. Pour chacune de ces 51 familles, ils ont attribue 3-4 individus a chacun de quatre traitements qui varient en eau et temperature. Ils ont observe de la plasticite phenotypique pour la periode de floraison en reponse a la fois a la temperature et a la disponibilite de l'eau, mais aucune variance genetique ou differenciation genetique de la plasticite phenotypique. Ces resultats indiquent que la plasticite phenotypique pourrait fournir une reponse rapide aux changements environnementaux, mais presentent peu de potentiel evolutif. A l'oppose de la plasticite phenotypique, la periode moyenne de floraison varie entre les familles et entre les populations, suggerant une base genetique et une adaptation dans les differentes populations. Le scenario le plus probable pour l'adaptation de cette espece au changement climatique consiste en une reponse rapide via la plasticite phenotypique suivie de selection qui engendre des changements microevolutifs du phenotype moyen.

Chemical contaminations can occur through exposure of foods to illegal additives, pesticides and fertilizer residues, toxic compounds formed by chemical reactions, and are easier to control than illnesses caused by microorganisms. In general, chemical reactions in food can be described using the first-order kinetic models. Food quality factors related to nutrition, color, texture, etc. are typically affected by temperature, pH, moisture content, as well as microbial growth. However, modeling the growth and inactivation of microorganisms is much more difficult and complex than that for chemical reactions. If harmful microbes are not eliminated during processing, their survival and growth may cause spoilage and foodborne illness. Food safety intervention technologies such as microwave heating, and modified packaging were discussed, as well as issues related to cross-contamination of foods during processing. Microbial food safety can be enhanced by the development of growth and inactivation modeling tools, world-wide data sharing, and collaboration in which the Pathogen Modeling Program (PMP) and ComBase can be utilized.

Physaria obcordata is a rare endemic of western Colorado. Plants are self-incompatible; they cannot reproduce sexually unless pollinators move pollen between flowers of different genets. We found no evidence that: seed production was limited by inadequate pollination or that pollinations between near neighbor plants (inbreeding depression) or between distant plants (outbreeding depression) resulted in reduced fruit or seed set. Examples are given of the potentially devastating effect of grazing on fruit and seed production. Preliminary evidence suggests that P. obcordata can hybridize with its common congener, P. acutifolia. Only crosses with P. obcordata as pollen recipient and P. acutifolia as pollen donor seemed fertile. Primary flower-visitors of P. obcordata are ground-nesting native bees in the families Andrenidae and Halictidae. Most species visiting the flowers of P. obcordata are generalists. Only two bee species were likely mustard specialists. The only non-bee visitor of any import was a dipteran, Gonia (Tachinidae). Predictions of the distances flown by common bee visitors were made using the equations of Greenleaf et al. (2007). No bee is likely to travel more than 1 km from its nesting site to visit P. obcordata flowers and most are likely to fly distances that are significantly less. The implications of flight range estimates for gene flow between Physaria populations and for pollinator protection are discussed. Several recommendations are made for conservation of P. obcordata and its attendant bees.

Peanut skins extracts (PSE) were prepared through a multisolvent extraction procedure. The PSE extended the lag phase growth of the 3 yeasts studied at a concentration of 1 mg/mL and at 10 mg/mL yeast growth was totally inhibited for 120 h. PSE was fractionated by normal phase high performance liquid chromatography and the active components/fractions were determined. Compounds present in the fractions were identified by liquid chromatography-mass spectrometry to determine the compounds responsible for inhibition. Fractions consisting mostly of A-type proanthocyanidin dimers, trimers, and tetramers showed the highest percent inhibition toward the yeasts tested in this study. Both optical density (OD) and standard enumeration plating methods were performed in this study. The OD method led to an overestimation of the inhibitory effects of PSE, the 2 methods agreed in respect to treatment effects but not the severity of the inhibition. Practical Application: There is a growing consumer demand for "fresh like" products containing reduced amounts of chemical preservatives without compromising food safety and quality. Therefore, the goal of this study was to determine if an extract of peanut skins containing flavonoid rich compounds could function as a natural antimicrobial in a model beverage system. Proteins were removed through the process of producing the peanut skin extract, thus it is unlikely to contain peanut allergens. The antimicrobial compounds mentioned in this study were successfully integrated into a model beverage system, and were found to have antimicrobial effect. However, the incorporation of these compounds would likely lead to negative sensory attributes at the concentration needed to achieve an appreciable antimicrobial effect alone.

This widely observed shift from grass to shrub dominance in rangelands worldwide has been heterogeneous in space and time largely due to cross-scale interactions among soils, climate, and land-use history. Our objective was to use a hierarchical framework to evaluate the relationship between spatial patterns in soil properties and long-term shrub dynamics in the northern Chihuahuan Desert of New Mexico, USA. To meet this objective, shrub patch dynamics from 1937 to 2008 were characterized at patch and landscape scales using historical imagery and a recent digital soils map. Effects of annual precipitation on patch dynamics on two soils revealed strong correlations between shrub growth on deep sandy soils and above-average rainfall years (r = 0.671, P = 0.034) and shrub colonization and below-average rainfall years on shallow sandy soils (r = 0.705, P = 0.023). Patch-level analysis of demographic patterns revealed significant differences between shrub patches on deep and shallow sandy soils during periods of above- and below-average rainfall. Both deep and shallow sandy soils exhibited low shrub cover in 1937 (1.0% plus or minus 2.3% and 0.3% plus or minus 1.3%, respectively [mean plus or minus SD]) and were characterized by colonization or appearance of new patches until 1960. However, different demographic responses to the cessation of severe drought on the two soils and increased frequency of wet years after 1960 have resulted in very different endpoints. In 2008 a shrubland occupied the deep sandy soils with cover at 19.8% plus or minus 9.1%, while a shrub-dominated grassland occurred on the shallow sandy soils with cover at 9.3% plus or minus 7.2%. Present-day shrub vegetation constitutes a shifting mosaic marked by the coexistence of patches at different stages of development. Management implications of this long-term multi-scale assessment of vegetation dynamics support the notion that soil properties may constrain grassland remediation. Such efforts on sandy soils should be focused on sites characterized by near-surface water-holding capacity, as those lacking available water-holding capacity in the shallow root zone pose challenges to grass recovery and survival.

We identified and synthesized seven male-specific volatile compounds. Three of these, dodecanal, (4R,11E)-tetradecen-4-olide, and (Z)-10-heptadecen-2-one, were the key behaviorally active components in flight tunnel bioassays. Male specificity was demonstrated by gas chromatographic comparison of male and female volatile emissions and whole body extracts. Identifications were aided by coupled gas chromatographic-mass spectrometric (GC-MS) analysis, microchemical reactions, NMR, chiral GC analysis, and GC and MS comparison with authentic standards. Both the racemic and chiral forms of the gamma -lactone, as well as both E- and Z-isomers were synthesized. Flight tunnel behavioral tests showed positive male and female S. agrili responses to both natural pheromone and synthetic blends, with upwind flight and landing on the source. Large field-cage tests, using yellow sticky traps baited with pheromone, captured approximately 50 % of the released male and female wasps in 24-h periods. The use of pheromone-baited traps in the field could simplify the current detection method for determining parasitoid establishment (i.e., laboriously felling and peeling ash trees for recovery of S. agrili from infested EAB larvae).

The pheromone, methyl (E)-3-(2-hydroxyethyl)-4-methyl-2-pentenoate, was discovered by gas chromatography-coupled electroantennogram detection (GC-EAD), and identified by gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance spectroscopy (NMR). The synthesis yielded an 86:14 mixture of methyl (E)-3-(2-hydroxyethyl)-4-methyl-2-pentenoate (active) and methyl (Z)-3-(2-hydroxyethyl)-4-methyl-2-pentenoate (inactive), along with a lactone breakdown product. The activity of the synthetic E-isomer was confirmed by GC-EAD, GC-MS, NMR, and bioassays. No antennal response was observed to the Z-isomer or the lactone. In a two-choice olfactometer bioassay, female D. abbreviatus moved upwind towards the synthetic pheromone or natural pheromone more often compared with clean air. Males showed no clear preference for the synthetic pheromone. This pheromone, alone or in combination with plant volatiles, may play a role in the location of males by female D. abbreviatus.

Three primary growth models were evaluated, including the Baranyi model, the Huang 2008 model, and a new growth model that is based on the communication of messenger signals during bacterial growth. A 5 strain cocktail of freshly prepared STEC was inoculated to raw ground beef samples and incubated at temperatures ranging from 10 to 35 degree C at 5 degree C increments. Minimum relative growth (<1 log10 cfu/g) was observed at 10 degree C, whereas at other temperatures, all 3 phases of growth were observed. Analytical results showed that all 3 models were equally suitable for describing the bacterial growth under constant temperatures. The maximum cell density of STEC in raw ground beef increased exponentially with temperature, but reached a maximum of 8.53 log10 cfu/g of ground beef. The specific growth rates estimated by the 3 primary models were practically identical and can be evaluated by either the Ratkowsky square-root model or a Belehradek-type model. The temperature dependence of lag phase development for all 3 primary models was also developed. The results of this study can be used to estimate the growth of STEC in raw ground beef at temperatures between 10 and 35 degree C. Practical Application: Incidents of foodborne infections caused by non-O157 Shiga toxin-producing Escherichia coli (STEC) have increased in recent years. This study reports the growth kinetics and mathematical modeling of STEC in ground beef. The mathematical models can be used in risk assessment of STEC in ground beef.

Methods: Data from the China Health and Nutrition Survey (CHNS) 1991 (n= 3895), CHNS 2004 (n= 1902), and the National Health and Nutrition Examination Survey (NHANES) 2003-2004 (n= 3344) were used to define the prevalence of underweight and overweight using the CDC and IOTF BMI cut-off points. Results: An upward shift in the BMI distribution was observed from the CHNS 1991 to CHNS 2004, and between the CHNS and NHANES 2004. The prevalence of underweight defined by the IOTF cut-off points was higher than that obtained using the CDC cut-off points; absolute differences between IOTF and CDC classifiers were 7%, 5%, and 2% in boys, and 12%, 11%, and 4% in girls in the CHNS 1991, CHNS 2004, and NHANES 2004, respectively. There was a greater consistency in the prevalence of overweight. The consistency of the two classification systems increased with the higher BMI distribution and was not affected significantly by ethnicity or age at menarche. Conclusions: The BMI distribution of a population can affect the classification of childhood underweight and overweight differentially as defined by the CDC and IOTF cut-off points, and thus should be considered in the interpretation of results in clinical and population settings.

Antibodies to T. gondii were determined in serum samples from 511 sheep from 8 farms in Durango State, Mexico, using the modified agglutination test (MAT). Sheep were raised in 3 geographical regions, i.e., mountainous (n == 68), semi-desert (n == 132), and valley (n == 311). Overall, T. gondii antibodies were found in 77 (15.1%%) of 511 sheep, with MAT titers of 1[ratio][ratio]25 in 27, 1[ratio][ratio]50 in 10, 1[ratio][ratio]100 in 11, 1[ratio][ratio]200 in 11, 1[ratio][ratio]400 in 8, 1[ratio][ratio]800 in 3, 1[ratio][ratio]1,600 in 4, and 1[ratio][ratio]3,200 in 3. The seroprevalence of T. gondii infection increased significantly with age, indicating post-natal transmission. In contrast, gender, breed, flock size, and geographic region did not significantly influence the seroprevalence. Seropositive sheep were found in 7 of 8 farms sampled. This is the first report of T. gondii infection in sheep in Durango State, Mexico. Results indicate that infected sheep are probably an important source of T. gondii infection for humans in Durango State.

Designated as T. boreoarcticus forma (f.) minor B, the males occurred with T. boreoarcticus f. major and T. borearcticus f. minor A in endemic populations of muskoxen (Ovibos moschatus wardi) and barrenground caribou (Rangifer tarandus groenlandicus) on Victoria Island, Nunavut, Canada, and in muskoxen and Peary caribou (Rangifer tarandus pearyi) on Banks Island, Northwest Territories, Canada. These specimens differ from conspecific morphotypes in the structure of the genital cone and Sjoberg's organ. Relative to T. boreoarcticus f. minor A, specimens of T. boreoarcticus f. minor B are consistently smaller, and mean dimensions for the bursa and spicules do not overlap. The robust spicules are similar in form, particularly in the relative length of the dorsal and ventral processes, but mean total length is substantially less in specimens of T. boreoarcticus f. minor B. Differences that distinguish the minor morphotypes of T. boreoarcticus parallel those demonstrated for the T. trifurcata and T. davtiani morphotypes in association with T. circumcincta sensu stricto. New host and geographic records include the 3 morphotypes of T. boreoarcticus in muskoxen and Peary caribou from Banks Island and in barrenground caribou from Victoria Island. Recognition of the ubiquitous nature of cryptic species emphasizes the need to effectively develop and use our collections-based resources and museum archives to build a robust understanding of the biosphere. Field inventory should include provisions for integrative approaches that preserve specimens suitable for comparative morphology, multi-faceted molecular investigations, and population genetics.

We found emerald ash borer infesting both introduced North American green ash (Fraxinus pennsylvanica Marshall) and native oriental ashes (F. mandshurica Rupr. and F. rhynchophylla Hance) in both regions. Emerald ash borer densities (larvae/m2 of phloem area) were markedly higher on green ash (11.3-76.7 in the Khabarovsk area and 77-245 in the Vladivostok area) than on artificially stressed Manchurian ash (2.2) or Oriental ash (10-59). Mortality of emerald ash borer larvae caused by different biotic factors (woodpecker predation, host plant resistance and/or undetermined diseases, and parasitism) varied with date, site, and ash species. In general, predation of emerald ash borer larvae by woodpeckers was low. While low rates (3-27%) of emerald ash borer larval mortality were caused by undetermined biotic factors on green ash between 2009 and 2011, higher rates (26-95%) of emerald ash borer larval mortality were caused by putative plant resistance in Oriental ash species in both regions. Little (<1%) parasitism of emerald ash borer larvae was observed in Khabarovsk; however, three hymenopteran parasitoids (Spathius sp., Atanycolus nigriventris Vojnovskaja-Krieger, and Tetrastichus planipennisi Yang) were observed attacking third - fourth instars of emerald ash borer in the Vladivostok area, parasitizing 0-8.3% of emerald ash borer larvae infesting Oriental ash trees and 7.3-62.7% of those on green ash trees (primarily by Spathius sp.) in two of the three study sites.

All studies were conducted in apple orchards, Malus domestica Borkhausen, treated with sex pheromone dispensers during 2010. Septa were loaded with codlemone, DMNT, and pear ester individually or codlemone with either DMNT or pear ester together (combo lures). Polyethylene vials loaded with AA were added as a co-lure. Residual analyses of field-aged combo lures and weight loss of the AA co-lure were conducted. AA vials lost 50-150 mg wk-1. Weekly weight loss was not affected by field aging, but was closely correlated with the daily mean temperature. Pear ester was released from septa at a slightly higher but nonsignificant rate than codlemone. DMNT was released at a significantly higher rate than codlemone, and lures were effective for 4 wk. The addition of codlemone to traps baited with either host plant volatile plus AA had either no effect or significantly increased total moth catches. The addition of AA significantly increased the catch of female moths with either combo lure. Total moth catches in traps baited with pear ester or DMNT combo lures and AA did not differ and were either significantly higher or similar to the pear ester combo lure. These data suggest that codling moth may be more effectively monitored in sex pheromone-treated orchards with multi-component lures, including codlemone, AA, and host plant volatiles.

Evaluations were conducted in replicated plots (0.1-0.2 ha) in apple, Malus domestica (Borkhausen) during both generations of codling moth from 2007 to 2009. Dispensers were applied at 1,000 ha-1 Male captures in traps baited with virgin female moths and codlemone lures were recorded. Residual analysis of field-aged dispensers over both moth generations was conducted. Dispensers exhibited linear declines in release rates of both attractants, and pear ester was released at a significantly higher rate than codlemone during both time periods. The proportion of virgin female-baited traps catching males was significantly lower with combo dispenser TRE24 (45/110, mg codlemone/mg pear ester) during the second generation in 2007 and the combo dispensers TRE144 (45/75) and TRE145 (75/45) during the first generation in 2008 compared with Isomate-C Plus. Similarly, male catches in female-baited traps in plots treated with the combo dispensers TRE144 during the first generation in 2008 and TRE23 (75/110) during the second generation, in 2007 were significantly lower than in plots treated with Isomate-C Plus. No significant differences were found for male catches in codlemone-baited traps in plots treated with Isomate-C Plus and any of the combo dispensers. However, male catches were significantly lower in plots treated with Cidetrak CM (codlemone-only dispenser) than the combo TRE144 dispenser during both generations in 2009.

Among these are the factors regulating the adult diapause. Reports of recent studies questioned the validity of earlier reports of diapause in L. hesperus, in part because of the demonstrated loss of diapause response in insects obtained from long-standing laboratory colonies. However, use of laboratory reared insects would facilitate additional diapause research, so long as those insects exhibit a diapause response similar to that of the field population. L. hesperus, originating as eggs from field-collected insects, were reared in the laboratory for four generations to examine corresponding changes in selected biological characteristics. Over the course of the four generations, incidence of diapause in both L. hesperus genders decreased whereas the frequency of oviposition by virgin females increased. Measurable changes were not observed in frequency of occurrence of a specific fat body type (glass bead fat) or nymphal development time. These results suggest L. hesperus used in diapause research should be as close to the field population as possible, but no further removed than three generations. Results further demonstrate variability among different biological characteristics in their responses to selection from laboratory rearing. Collectively, these findings demonstrate the importance of understanding the influences of rearing on specific biological characteristics under study, and the need to verify the similarity of laboratory-reared insects to their native counterparts in studies used to draw inferences regarding the field population.

Spatial patterns in physical (substrate depth, temperature, water content), chemical (pH, electrical conductivity [EClab], total nitrogen [N] and carbon [C], ammoniacal nitrogen [NH4-N], extractable phosphorus [P]), and biological (microbial respiration rate) substrate properties for two feeding sites were estimated and the correlations between these properties and adult emergence were characterized. Hay feeding sites had a circular footprint with residues extending approximately approximately 7 m from the feeder. With the exception of extractable P and total N, all substrate properties exhibited spatial patterns centered on the feeder location. Adult stable fly emergence densities were significantly correlated with substrate microbial respiration rate, NH4-N concentration, EClab, total C concentration, pH, and moisture content. Logistic regression indicated that EC best predicted the probability of stable flies emerging from a substrate and that the other properties did not provide additional information. A better understanding of the physical, chemical, and biological conditions needed for stable fly larval development may help in identifying previously unrecognized developmental habitats and management of this pest. Targeted implementation of management practices such as sanitation and chemical treatments can be applied to smaller areas reducing labor and improving cost effectiveness.

However, no clear relationship between Lygus population level and plant injury has been established. Agedependent feeding activity by L. hesperus is a possible source of variation that has not been examined for its influence in studies of the impact of Lygus on cotton. Recent video-based laboratory studies indicated that feeding behaviors and trivial movement varied among L. hesperus adults of different gender and reproductive states (prereproductive; reproductive and unmated; and reproductive and mated). We compared within-plant distributions and accumulations of feeding injury to intact cotton plants corresponding to adult L. hesperus of different gender and reproductive states. Adult females, regardless of reproductive state, were observed on squares and axillary buds more often than were males. Additionally, prereproductive adults were observed on squares and axillary buds more often than were mated or unmated reproductive adults, regardless of gender. Plants that were exposed to prereproductive adults exhibited more abscised squares and more squares with injured anthers compared with plants exposed to reproductive adults. However, feeding injury did not differ by insect mating status or gender. These results are consistent with results of our previous video-based assays, and indicate adult reproductive state represents a source of variation that should be controlled in studies to evaluate Lygus-induced injury to cotton and other crop plants.

Endemic levels of the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin can occur in pecan orchards and contribute to natural control of C. caryae. Commercial formulations of the fungus can also be applied for suppression of C. caryae. We hypothesized that a clover cover crop enhances B. bassiana efficacy and persistence (e.g., by protecting the fungus against abiotic environmental stresses). The hypothesis was tested by conducting field trials in a pecan orchard in Byron, GA, in 2009 and 2010. The study included four treatments arranged in a factorial with two levels of fungus (endemic fungus only, and application of a commercial B. bassiana product), and two levels of clover (white clover, Trifolium repens L., and no clover). Fungal persistence was measured by determining the number of CFUs per gram of soil over time (during 42 d postapplication of B. bassiana in 2009 and 29 d in 2010). Efficacy was measured by capturing naturally emerging C. caryae and subsequently determining mortality and mycosis (over 24 d in 2009 and 17 d in 2010). In 2009, greater prevalence of B. bassiana conidia was detected in plots receiving fungal applications compared with no fungus applications, and no clear effect of clover was observed in plots receiving B. bassiana applications in either year. In 2010, B. bassiana prevalence in the endemic fungus plus clover treatment was higher than fungus without clover, and was similar to plots receiving additional B. bassiana applications. Given that we observed enhanced persistence of endemic B. bassiana in 2010 but not 2009, the impact of clover appears to be a cumulative effect. Mortality of C. caryae (averaged over the sampling periods) ranged between 68-74% in plots receiving B. bassiana applications and 51-56% in plots with endemic fungus only. C. caryae mortality and mycosis data also provided evidence that endemic B. bassiana efficacy was enhanced by clover relative to plots without clover (with no clear clover effect on plots receiving fungus applications). Thus, we conclude that natural control of C. caryae can increase when clover is grown in pecan orchards with endemic populations of B. bassiana.

A related biocontrol agent, Austromusotima camptozonale, had previously failed to establish despite several years of releases. Life history studies were conducted to determine whether aspects of the reproductive biology of N. conspurcatalis might account for these different outcomes. At 26.5 degree C, development from egg to adult averaged 22.2 +/- 0.1 d, with 75% of larvae emerging as adults. The sex ratio averaged 1:0.8 ([male[male:[female][female]), with both sexes emerging at the same time. Female moths typically mated once, on the first night after emergence, and began oviposition the next night. Females laid half their eggs on the first night and lived an average of 10.7 +/- 0.8 d. Individual females maintained in cages with a male-biased sex ratio (3[male[male:1[female][female]) produced significantly more larvae over their lifetime (140 +/- 6.6 larvae) than individual females maintained at a ratio of 1[male[male:1[female][female] (111 +/- 9.1 larvae). Sexual selection, either through 'male-male competition' or 'female choice' was likely responsible for this result, because there were no significant differences in mating frequency, duration of ovipositional period or female longevity to otherwise explain the difference. Two-fold greater lifetime reproductive output (average 127 +/- 6.3 larvae) and deposition of half this output on the first night of oviposition, likely contributed to rapid field establishment of N. conspurcatalis compared with A. camptozonale.

Pitfall trapping, leaf litter, and hand collections, as well as protein and sugar baits were used to characterize the resident ant community in this habitat. Estimates of faunal richness as impacted by the blueberry crop stage (pruned or fruit-bearing), methods of pest management (grower standard, reduced-risk, or organic), and location within fields (middle, edge, or forested perimeters) were determined. In total, 42 species were collected from blueberry fields, comprising five subfamilies and 15 genera. Myrmica sculptilis Francoeur, Myrmica americana Weber, and Formica exsectoides Forel were the three most abundant species. Formica ulkei Emery, Myrmecina americana Emery, and Leptothorax canadensis Provancher represent new species records for Maine. Ants were most diverse in organic fields, and along the edge and within the wooded areas surrounding fields. Results suggest insecticide application reduces ant diversity.

(Lepidoptera: Crambidae) have been unsuccessful. Experiments were conducted to investigate the feasibility of using an alternative larval host and host plants to overcome barriers preventing establishment. In addition, we evaluated C. flavipes' ability to search for D. saccharalis in sugarcane without above-ground internodes. Diatraea evanescens Dyar (Lepidoptera: Crambidae) was investigated as an alternative host for C. flavipes. Cotesia flavipes was reared for five generations on D. evanescens without any indication of diminishing fitness as measured by days to parasite pupation and average cocoon mass weight. However, there was a significant reduction in percent parasitism, cocoon mass weight, and percent emergence when C. flavipes parasitized D. evanescens as compared with D. saccharalis, resulting in a 75% reduction in the gross reproductive rate (R0). Greenhouse studies indicated little difference in parasitism of D. saccharalis on the weed hosts johnsongrass, Sorghum halepense (L.), and vaseygrass, Paspalum urvillei Steud. However, when planted as refuge plots, we found it difficult to establish infestations of D. saccharalis in either of these hosts, or in two energy sugarcanes. After 3 yr of infesting host plants and releasing parasitoids only one parasitized D. saccharalis larvae was recovered within the johnsongrass refuge. Diatraea evanescens readily established in vaseygrass; however, these larvae appear inaccessible to C. flavipes. In contrast, parasitism of D. saccharalis by C. flavipes infesting young sugarcane was 30%.

Habitat complexity measures are often made using visual approximations or total station (TS) surveying that can be subjective and have limited spatial resolution. Terrestrial laser scanning (TLS) can measure topography at a high resolution and accuracy. Two methods, TS surveying and TLS, were compared for measuring complex topography in a boulder-dominated 100 m forested reach of the Staunton River in Shenandoah National Park, Virginia. The mean absolute difference between the two datasets was 0.11 m with 82.3 percent of the TS data within plus or minus 0.1 m of TLS. The TLS dataset was processed to remove vegetation and create a 2 cm digital elevation model (DEM). An algorithm was developed for delineating rocks within the stream channel from the DEM. A common ecological metric based on the structural complexity of the stream, percent in-stream rock cover, was calculated from the TLS dataset, and the results were compared to estimates from traditional methods. This application illustrates the potential of TLS to quantify habitat complexity measures in an automated, unbiased manner.

Unfortunately, many of the less diverse saproxylic taxa, including Hemiptera, remain largely unstudied. An effort to rear insects from dead wood taken from two forest types (an upland pine-dominated and a bottomland mixed hardwood), three tree species (Liquidambar styraciflua [Sweetgum], Pinus taeda [LoblollyPine], and Quercus nigra [WaterOak]), and two wood postures (standing snags and fallen logs) in South Carolina produced 435 Hemiptera belonging to eight families and 14 species. The most common (>25 individuals) species were Lyctocoris stalii, Systelloderes inusitatus, Lasiochilus fusculus, Mezira granulata, Calisius contubernalis (a new state record), and Catonia sp. Lyctocoris stalii and Systelloderes inusitatus were almost exclusively captured in the upland and bottomland forest, respectively. Systelloderes inusitatus and Mezira granulata were recovered only from logs. Catonia sp. only emerged from P. taeda logs. Among the less common species, all but two of the 21 specimens of Peritropis saldaeformis were collected from snags. Similarly, all four specimens of Calliodis temnostethoides collected emerged from the crowns of snags. These findings strongly indicate that saproxylic Hemiptera are unevenly distributed among forests, tree species, and wood postures in the southeastern United States. A wide variety of dead wood is clearly necessary to maintain this fauna.

Eighteen maize genotypes including GEM varieties and commercial checks were evaluated in a 2-year field study for dry matter yield, moisture at harvest and sugar produced by hydrolysis of whole plants and cobs. There were no significant correlations between any of the traits measured, suggesting that it should be possible to improve yield with quality traits using a selection index. A brown midrib variety was in the top significance group for hydrolysis traits, underscoring the impact of this mutation on the digestibility of lignocellulosic biomass. Commercial varieties tended to have superior dry matter yield, while several GEM lines ranked highly for sugar produced by hydrolysis of whole plants. Selection indices that take both sugar produced by hydrolysis and dry matter yield into account produced rankings of the germplasm used in this study that were markedly different than rankings based on either trait alone.

An enzyme-linked immunosorbent assay (ELISA) using an antibody specific to Fusarium was proposed as an alternative for measuring FHB instead of counting infected kernels per spike. Cleistogamy (closed flowering) may be an avoidance mechanism for FHB resistance. This study was conducted to determine whether quantitative trait loci (QTL) for Fusarium ELISA were colocated with QTL for FHB, DON, heading date, height and spike density and/or the gene for cleistogamy. Doubled haploid lines from Zhedar 2/ND9712//Foster were tested in ten environments and used to develop a 260-marker linkage map. QTL analysis located 24 significant regions for the six traits. The effect of cleistogamy on resistance was unclear and environment specific. Of the two QTL located for ELISA, only one corresponded with a QTL for FHB, but large allelic differences in ELISA were found for the regions significantly associated with FHB and DON, indicating that ELISA could be a simpler method to identify lines with FHB resistance and low DON.

Non-biotic soil-surface crust is one of the major factors limiting reseeding success by acting as a barrier to seedling emergence. 2.The objective of this study was to determine whether seedling emergence could be improved by agglomerating multiple seeds into a single pellet, so that the seedlings growing from the pellet will collectively generate sufficient force to penetrate the soil crust. To evaluate this technology, we compared seedling emergence and biomass production from agglomerated, single and non-coated seed (control) of Pseudoroegneria spicata. In the greenhouse, seeds were sown in either crust-forming clay or non-crusting sandy soil and studied for a 25-day period. Starting seed density was constant across treatments. 3.In the clay soil, seedling emergence from the agglomeration treatment was 1.3 and 1.9 times higher than the single seed coating and control, respectively. In the sandy soil, the agglomeration and single seed coating responded similarly, producing 1.4 times more seedlings than the control. 4.Biomass production followed a similar trend as plant density. In the clay soil, increased biomass of the agglomeration treatment was not only because of higher plant densities but was also a product of having greater biomass per plant. 5.Synthesis and applications. This short-duration 'proof-of-concept' study indicates that both the seed coating materials used to form the agglomerates and the act of agglomerating the seeds together improve P. spicata emergence and plant growth. These results also demonstrate that in the early seedling stage, facilitation outweighs competition in agglomeration plantings. Additional research is needed to verify these results in the field.

In evaluating plants for environmental stress tolerance, it is important to monitor changes in their physical environment under natural conditions, especially when there are multiple stress factors, and integrate this information with their physiological responses. A low-cost microcontroller-based monitoring system was developed to automate measurement of canopy, soil and air temperatures, and soil moisture status in field plots. The purpose of this study was to examine how this system, in combination with physiological measurements, could assist in detecting differences among corn genotypes in response to moisture deficit and heat stress. Three commercial hybrids and two inbred germplasm lines were grown in the field under irrigated and non-irrigated conditions. Leaf water potential, photosynthetic pigments, cell membrane thermostability (CMT) and maximum quantum efficiency of photosystem II (Fv/Fm) were determined on these genotypes under field and greenhouse conditions. Variations observed in air and soil temperatures, and soil moisture in plots of the individual corn genotypes helped explain their differences in canopy temperature (CT), and these variations were reflected in the physiological responses. One of the commercial hybrids, having the lowest CT and the highest CMT, was the most tolerant among the genotypes under moisture deficit and heat stress conditions. These results demonstrated that the low-cost microcontroller-based monitoring system, in combination with physiological measurements, was effective in evaluating corn genotypes for drought and heat stress tolerance.

Fish were challenged, by waterborne exposure to F. columnare in an ultra-low flow-through water delivery system, and treated with CuSO4 at 4.2 and 2.1mgL-1 at 5.5h post challenge for 4h. Bacterial challenged non-treated fish acted as a positive control and non-challenged non-treated fish acted as a negative control. Fish challenged with F. columnare and treated with CuSO4 at 4.2 and 2.1mgL-1 post challenge had mortalities of 6.4% and 18.3%, respectively, compared with the positive control, which had 90.2% mortality. The mortality of challenged fish treated with CuSO4 at 4.2 and 2.1mgL-1 was significantly different from the positive control. There was no significant difference between the mortalities of the 4.2 and 2.1mgL-1 treatments. The results suggest that CuSO4 has clear therapeutic value against columnaris infections.

These attributes are of major agronomic importance as they determine the adaptability of a plant to various methods of cultivation, which in turn influence harvest index and grain yield. We detected a recessive mutant from the aromatic cultivar 'Khao Dawk Mali 105' (KDM105), which exhibits a plant architecture with shorter height, shorter and more erect leaves and panicle than the wild type. The mutant line was named ser for short and erect rice. The ser mutation was induced by 30kilorads of gamma radiation. Averaged from 10 mature plants grown in the greenhouse, the ser had 104.6 degree smaller angle between the flag leaf and culm, compared with the KDM105 wild type. For the leaf below the flag leaf, the ser mutant was 46.2 degree more erect than the wild type. The length of the flag, 2nd and 3rd leaf of the ser was 21.8, 24.4 and 16.3cm shorter than the wild type, respectively. Plant height as measured from soil surface to flag leaf tip was reduced by 43.5cm, while plant height measured from soil to panicle tip was reduced by 28.5cm in the ser in comparison with the wild type. Characterization of 10 booting plants each of the ser, wild and their reciprocal F1 populations confirmed the shortening mutation with no cytoplasmic effect. The ser was identically monomorphic to its wild type and F1 hybrid for all 11 SSR markers covering seven chromosomes, indicating a true mutation. In the F2 generation, a ratio of three wild type to one ser was observed, resulting in a chi 2 of 0.067 (P=0.795) for a single gene segregation and demonstrating a recessive mutation. The ser will be an ideal material for the study on gene pleiotropy and metabolism functions. Further, the pleiotropic gene in such a premium quality cultivar globally known will be valuable for improving plant architecture in rice cultivars.

Although spinach crops grown in this region for fresh and processing commercial production do not display Verticillium wilt symptoms, spinach seeds produced in the United States or Europe are commonly infected with V. dahliae. Planting of the infected seed increases the soil inoculum density and may introduce exotic strains that contribute to Verticillium wilt epidemics on lettuce and other crops grown in rotation with spinach. A sensitive, rapid, and reliable method for quantification of V. dahliae in spinach seed may help identify highly infected lots, curtail their planting, and minimize the spread of exotic strains via spinach seed. In this study, a quantitative realtime polymerase chain reaction (qPCR) assay was optimized and employed for detection and quantification of V. dahliae in spinach germ-plasm and 15 commercial spinach seed lots. The assay used a previously reported V. dahliae-specific primer pair (VertBt-F and VertBt-R) and an analytical mill for grinding tough spinach seed for DNA extraction. The assay enabled reliable quantification of V. dahliae in spinach seed, with a sensitivity limit of approximately 1 infected seed per 100 (1.3% infection in a seed lot). The quantification was highly reproducible between replicate samples of a seed lot and in different real-time PCR instruments. When tested on commercial seed lots, a pathogen DNA content corresponding to a quantification cycle value of greater than or equal to 31 corresponded with a percent seed infection of less than or equal to 1.3%. The assay is useful in qualitatively assessing seed lots for V. dahliae infection levels, and the results of the assay can be helpful to guide decisions on whether to apply seed treatments.

Root colonization by 2,4-DAPG-producing P. fluorescens strains Pf-5 (genotype A), Q2-87 (genotype B), Q8r1-96 (genotype D), and HT5-1 (genotype N) produced induced systemic resistance (ISR) in Arabidopsis thaliana accession Col-0 against bacterial speck caused by P. syringae pv. tomato. The ISR-eliciting activity of the four bacterial genotypes was similar, and all genotypes were equivalent in activity to the well-characterized strain P. fluorescens WCS417r. The 2,4-DAPG biosynthetic locus consists of the genes phlHGF and phlACBDE. phlD or phlBC mutants of Q2-87 (2,4-DAPG minus) were significantly reduced in ISR activity, and genetic complementation of the mutants restored ISR activity back to wild-type levels. A phlF regulatory mutant (overproducer of 2,4-DAPG) had ISR activity equivalent to the wild-type Q2-87. Introduction of DAPG into soil at concentrations of 10 to 250 mu M 4 days before challenge inoculation induced resistance equivalent to or better than the bacteria. Strain Q2-87 induced resistance on transgenic NahG plants but not on npr1-1, jar1, and etr1 Arabidopsis mutants. These results indicate that the antibiotic 2,4-DAPG is a major determinant of ISR in 2,4-DAPG-producing P. fluorescens, that the genotype of the strain does not affect its ISR activity, and that the activity induced by these bacteria operates through the ethylene- and jasmonic acid-dependent signal transduction pathway.

However, our analysis shows that this approach severely underestimates the effect of the first and last observation. To get a better estimate of disease progress, we have developed a new formula termed the area under the disease progress stairs (AUDPS). The AUDPS approach improves the estimation of disease progress by giving a weight closer to optimal to the first and last observations. Analysis of real data indicates that AUDPS outperforms AUDPC in most of the tested trials and may be less precise than AUDPC only when assessments in the first or last observations have a comparatively large variance. We propose using AUDPS and its standardized (sAUDPS) and relative (rAUDPS) forms when combining multiple observations from disease progress experiments into a single value.

The Chesapeake Bay is threatened by excessive nutrient loadings, and, according to the US Environmental Protection Agency (USEPA), manure is the source of 18% of the nitrogen and 27% of the phosphorus entering the Chesapeake Bay annually (figure 1) (Chesapeake Bay Program 2010). Developing economical, practical, and effective manure management options for livestock producers will not only contribute to the restoration of the Chesapeake Bay, but will also provide a model for other areas where water quality and livestock production objectives must be balanced.

Land managers typically strive to enhance particularly desirable services. For example, farmers plant crops and manage the soil and hydrologic conditions to favor crop production. In agricultural regions such as the US Corn Belt, exceptionally high agricultural production has been achieved, but at the expense of other ecosystem services, including abundant wildlife and clean water. In the past, land managers were unaware of these tradeoffs or simply considered them less important in favor of a collective mindset to maximize agricultural production. More recently, however, there has been rising demand for a broader range of ecosystem services coupled with documented degradation of landscape capabilities to provide them. Concern over these circumstances has grown among policymakers, scientists, and conservationists (MEA 2005), and there is now a general recognition that we must be more deliberate in managing our agricultural landscapes for multiple ecosystem services (Brandt and Vejre 2004; Foley et al. 2005; Palmer et al. 2004; Secchi et al. 2008). How should conservation planners go about this task? What methods are available to guide them toward this goal? In this paper, we present a conceptual framework and discussion of some approaches to conservation planning that may help to move this endeavor forward.

Angular lesions, dark brown at the edges and tan at the interior, eventually engulfed leaves of mature, fruit bearing trees. Additional lesions were seen on petioles and stems, resulting in stem girdling. Flower clusters were also attacked, but fruit lesions were not observed. Sporulation was evident only on stem tissue. In greenhouse-cultivated 3- to 8-month-old immature plants were found to be infected in the foliar and apical regions, resulting in death. Cultures obtained from surface-sterilized leaf and stem tissue of multiple disease samples cultivated on potato dextrose agar consistently resulted in a single fungal isolate. Molecular identification was carried out by sequence analysis of the region amplified using ITS1 forward and ITS4 reverse primers (ITS1 and 2, 5.8S ribosomal RNA). Full matches were found to Glomerella acutata (anamorph Colletotrichum acutatum Simmonds). A representative sequence was submitted to GenBank as JN863589. Cultures were reddish gray with masses of macroscopically mucilaginous orange-brown spores. Conidia were fusiform, measuring 14.0 plus or minus 2.3 x 5.7 plus or minus 0.7 mu m. No setae were present, but structures resembling immature perithecia were present, embedded in the agar, a characteristic of C. acutatum Group D isolates (2). Six immature plants (5 months old) and three mature plants (2 years old) were spray inoculated with 1 x 10 super(4) conidia per ml of water into apical regions and on the upper foliage. Plants were enclosed in clear plastic bags and incubated for 3 days. Two noninoculated plants of each age were maintained as controls. Bags were removed and plants were maintained in the greenhouse at 25 degree C. Within 2 weeks, all inoculated plants expressed disease symptoms. Lesions on the foliage were evident as well as the apical regions. Lesions progressed, killing the upper regions of the plant within 1 month. Isolations consistently resulted in cultures of C. acutatum. A culture obtained from infected tissue derived from the first inoculation study was used to repeat Koch's postulate. Anthracnose of tamarillo has been reported in South America and New Zealand where commercial production is concentrated, however, it is primarily a fruit disease (1). Our isolate is principally a foliar and stem pathogen. Host range for C. acutatum is wide enough that our isolate likely originated from another host since there is no widespread tamarillo production in the United States. Interestingly, solanaceous crop plants are generally subject to infection by C. coccodes, not C. acutatum, however, this may be changing (3).

G. Winter, is among the most destructive diseases of the two-needle hard pine in the Northern Hemisphere, including Scots pine but also several Mediterranean pines in southern Europe (2, 3). This heteroecious rust has numerous alternate herbaceous hosts spanning different plant families, thereby contributing to epidemic outbreaks when environmental conditions for infection are optimal (2, 3). The main alternate host in Europe is the white swallow-wort, Vincetoxicum hirundinaria Medik, a herbaceous perennial in the milkweed family (Asclepiadaceae). At the southwestern edge of its distribution, V. hirundinaria co-occurs with the black swallow-wort, V. nigrum (L.) Moench and cases of misidentification between the two species are not uncommon. Little to no disease occurs to V. nigrum likely because phenanthroindolizidine alkaloid antimicrobial compounds are produced in the weed. In 1918, occurrence of C. flaccidum was reported in Spain and Portugal on black and white swallow-worts albeit as C. asclepadium (1). In the early summer of 2011, at Saint Clement de Riviere in southern France, we detected orange-yellow rust pustules on the lower leaf surfaces of several black swallow-worts growing near Aleppo pines (Pinus halepensis). These orange-yellow pustules were erumpent uredinia in groups (range = 137 to 400 mu m in diameter) with peridia that broke with the production of uredinospores. The latter were moderately echinulate, light yellow, broadly ellipsoid (length = 23 plus or minus 4 mu m and range = 11 to 33 mu m; width = 15 plus or minus 2 mu m and range = 9 to 20 mu m) with walls of 1 to 2 mu m thick (mean 1.3 plus or minus 0.2 mu m). Hair-like columnar telia (length = 1.123 + 131 mu m and range = 976 to 1,280 mu m; width = 136 plus or minus 28 mu m and range = 104 to 176 mu m) were mostly formed from uredinia. Telia were hypophyllous and reddish orange. Teliospores were orange-yellow and ellipsoidal to cylindrical (length 26.3 plus or minus 6.2 mu m and range 13.5 to 46 mu m; width = 10.5 plus or minus 1.8 mu m and range = 6.9 to 14.9 mu m). Morphological features of these fruiting structures were consistent with those of C. flaccidum (Alb. & Schwein.) G. Winter on white swallow-worts (2). Additional confirmation was provided by sequencing the two internal transcribed spacer regions (ITS1 and ITS2) and the 5.8S gene (4). The sequence was 843 bp long (GenBank Accession No. JN802139), 99.7% similar to C. flaccidum found on Melampyrum in Finland (Accession No. JF13709), and 99.4% similar to C. flaccidum found on pines in Italy (Accession No. X83900). Voucher material has been deposited at the Herbarium of Montpellier's University under the collection Accession No. MPU0188846. To our knowledge, this is the first report of the occurrence of uredinia and telia of C. flaccidum on black swallow-worts clearly identified in France. The occurrence of the rust on this understory vine is of critical importance for the economic sustainability of pine forests in France, especially when they are heavily constrained by drought and fire.

To better understand the possible role of RNA silencing in disease induction, a combination of microarray analysis and large-scale RNA sequence analysis was used to compare changes in tomato gene expression and microRNA levels associated with PSTVd infection in two tomato cultivars plus a third transformed line expressing small PSTVd small interfering RNAs in the absence of viroid replication. Changes in messenger (m)RNA levels for the sensitive cultivar 'Rutgers' were extensive, involving more than half of the approximately 10,000 genes present on the array. Chloroplast biogenesis was down-regulated in both sensitive and tolerant cultivars, and effects on mRNAs encoding enzymes involved in the biosynthesis of gibberellin and other hormones were accompanied by numerous changes affecting their respective signaling pathways. In the dwarf cultivar 'MicroTom', a marked upregulation of genes involved in response to stress and other stimuli was observed only when exogenous brassinosteroid was applied to infected plants, thereby providing the first evidence for the involvement of brassino-steroid-mediated signaling in viroid disease induction.

This hypothesis has garnered substantial support at coarse scales. However, at finer scales, the influence of traits and niche use on invasibility and invader impacts is poorly understood. Within grasslands of western Montana, USA, we compared morphological and phenological traits for five top exotic invasive forbs and five dominant native forbs using multivariate techniques to examine niche separation between exotics and natives. Exotic forbs differed from native forbs in multivariate space. Phenologically, native forbs synchronized vegetative growth with bolting and flowering early in spring. In contrast, exotics initiated vegetative growth concurrent with natives but bolted and flowered later. Morphologically, vegetative growth of exotics was three times shorter and narrower, but flowering stem growth was 35% taller and 65% wider than the natives. Collectively, these patterns suggest different strategies of resource uptake and allocation. Additionally, following wildfire, survival was four times higher for exotics compared to natives, and three times more of the surviving exotics flowered. The exotics we examined appeared to be exploiting an empty community-level niche. The resulting pattern of trait differences between exotics and natives suggests a predictable pattern of invasion and a predictable trajectory of community change. Our results illustrate how quantifying trait differences between invading exotics and natives at the within-community scale can improve understandings of community invasibility and invader impacts.

Here we focus on dynamics of forest structure, composition and microclimate, and how these interact in southern Appalachian riparian forests following invasion by hemlock woolly adelgid, HWA, Adelges tsugae. We measured and quantified changes in microclimate; canopy mortality; canopy and shrub growth; understory species composition; and the cover and diversity in riparian forests dominated by eastern hemlock Tsuga canadensis over a period of seven years. Treatments manipulated hemlock mortality either through invasion (HWA infested stands) or girdling (GDL) hemlock trees. Mortality was rapid, with 50% hemlock tree mortality occurring after six years of invasion, in contrast to more than 50% mortality in two years following girdling. Although 50% of hemlock trees were still alive five years after infestation, leaf area lost was similar to that of girdled trees. As such, overall responses over time (changes in light transmittance, growth, soil moisture) were identical to girdled stands with 100% mortality. Our results showed different growth responses of the canopy species, shrubs and ground layer, with the latter being substantially influenced by presence of the evergreen shrub, rhododendron Rhododendron maximum. Although ground layer richness in the infested and girdled stands increased by threefold, they did not approach levels recorded in hardwood forests without rhododendron. Increased growth of co-occurring canopy trees occurred in the first few years following hemlock decline, with similar responses in both treatments. In contrast, growth of rhododendron continued to increase over time. By the end of the study it had a 2.6-fold higher growth rate than expected, likely taking advantage of increased light available during leaf-off periods of the deciduous species. Increased growth and dominance of rhododendron may be a major determinant of future responses in southern Appalachian ecosystems; however, our results suggest hemlock will be replaced by a mix of Acer, Betula, Fagus and Quercus canopy genera where establishment is not limited by rhododendron.

The isolate displayed a narrow substrate range but wide temperature and pH ranges atypical of ruminal bacteria and a maximum specific growth rate near the typical liquid dilution rate of the rumen. Quantitative real-time PCR revealed that C. kluyveri was widespread among bovine ruminal samples but was present at only very low levels (0.00002% to 0.0002% of bacterial 16S rRNA gene copy number). However, the species was present in much higher levels (0.26% of bacterial 16S rRNA gene copy number) in lucerne silage (but not maize silage) that comprised much of the cows' diet. While C. kluyveri may account for several observations regarding ethanol utilization and volatile fatty acid production in the rumen, its population size and growth characteristics suggest that it is not a significant contributor to ruminal metabolism in typical dairy cattle, although it may be a significant contributor to silage fermentation. The ability of unadapted cultures to produce substantial levels (12.8 gL super(-1)) of caproic (hexanoic) acid in vitro suggests that this strain may have potential for industrial production of caproic acid.

Electron microscopy revealed a small virion (44-nm-diameter icosahedral capsid) with a short, non-contractile tail, indicative of a member of the family Podoviridae. The phage had a linear, double-stranded DNA genome of 18,919 base pairs (bp) with 41 bp inverted terminal repeats and a type B DNA polymerase, which are characteristics of members of the subfamily Picovirinae. Out of 22 predicted genes in the genome, ten had significant sequence similarity to proteins of known function. Three distinct genes with lytic domains were identified, including a zinc carboxypeptidase domain that has not been previously reported in viruses. The Phi CP24R genome described herein is only the second Clostridium perfringens podovirus genome reported to date.

To address larger ecosystem scales, herein we show that excellent uniformity of the warming can be achieved using nested hexagonal and rectangular arrays. Energy costs depend on the overall efficiency (useable infrared energy on the plot per electrical energy in), which varies with the radiometric efficiency (infrared radiation out per electrical energy in) of the individual heaters and with the geometric efficiency (fraction of thermal radiation that falls on useable plot area) associated with the arrangement of the heaters in an array. Overall efficiency would be about 26% at 4 ms super(-1) wind speed for a single hexagonal array over a 3-m-diameter plot and 67% for a 199-hexagon honeycomb array over a 100-m-diameter plot, thereby resulting in an economy of scale.

AN - 1008831088; 22429217 AB - A monoclonal antibody-based electrochemical luminescence method was developed for detecting and quantifying ricin in liquid egg, with a limit of detection of 0.2 ng/mL. Because this highly toxic protein, present in the seeds of Ricinus communis (castor), has been used for intentional poisoning in the past, it is important to have sensitive and reliable analytical methodology to detect ricin in food matrices such as liquid egg. The detection of this quantity of pure or crude ricin spiked into commercial samples of liquid egg provides approximately 50000-fold greater sensitivity than required to detect a toxic dose of ricin (>1 mg) in a 100 g sample. Because ricin has been used for intentional poisoning, there is a need for analytical methodology to detect ricin in food matrices to assure a safe food supply. Using monoclonal antibodies to ricin developed in our laboratory, we explored an assay readout system known as electrochemiluminescence.

AN - 959150043; 22394556 AB - Sorption and degradation are the primary processes controlling the efficacy and runoff contamination risk of agrochemicals. Considering the longevity of biochar in agroecosystems, biochar soil amendment must be carefully evaluated on the basis of the target agrochemical and soil types to achieve agricultural (minimum impact on efficacy) and environmental (minimum runoff contamination) benefits. In this study, sorption-desorption isotherms and kinetics of triazine (deisopropylatrazine) and organophosphorus (malathion, parathion, and diazinon) pesticides were first investigated on various soil types ranging from clayey, acidic Puerto Rican forest soil (PR) to heavy metal contaminated small arms range (SAR) soils of sandy and peaty nature. On PR, malathion sorption did not reach equilibrium during the 3 week study. Comparison of solution-phase molar phosphorus and agrochemical concentrations suggested that degradation products of organophosphorus pesticides were bound on soil surfaces. The degree of sorption on different soils showed the following increasing trend: deisopropylatrazine < malathion < diazinon < parathion. While sorption of deisopropylatrazine on SAR soils was not affected by diazinon or malathion, deisopropylatrazine suppressed the sorption of diazinon and malathion. Deisopropylatrazine irreversibly sorbed on biochars, and greater sorption was observed with higher Brunauer-Emmett-Teller surface area of biochar (4.7-2061 mg g(-1)). The results suggested the utility of biochar for remediation of sites where concentrations of highly stable and mobile agrochemicals exceed the water-quality benchmarks.

AN - 922502871; 22285533 AB - Contamination of corn, cotton, peanuts and tree nuts by aflatoxins is a severe economic burden for growers. A current biocontrol strategy is to use non-aflatoxigenic Aspergillus flavus strains to competitively exclude field toxigenic Aspergillus species. A. flavus K49 does not produce aflatoxins and cyclopiazonic acid (CPA) and is currently being tested in corn-growing fields in Mississippi. We found that its lack of production of aflatoxins and CPA resulted from single nucleotide mutations in the polyketide synthase gene and hybrid polyketide-nonribosomal peptide synthase gene, respectively. Furthermore, based on single nucleotide polymorphisms of the aflatoxin biosynthesis omtA gene and the CPA biosynthesis dmaT gene, we conclude that K49, AF36 and previously characterized TX9-8 form a biocontrol group. These isolates appear to be derived from recombinants of typical large and small sclerotial morphotype strains. This finding provides an easy way to select future biocontrol strains from the reservoir of non-aflatoxigenic populations in agricultural fields. Published by Elsevier B.V.

Solid waste management facilities (e.g., landfills) are very attractive to and used by many birds, resulting in a variety of health and safety problems, including disease transmission to humans and increased risk of wildlife-aircraft collisions. In the United States, the Federal Aviation Administration recommends municipal solid waste management facilities (e.g., landfills, transfer stations) not be sited within 8km of an airport. Little information is available regarding the attractiveness of transfer stations to birds or the factors that might influence avian use, particularly on a national scale. The objectives of my study were to: (1) quantify avian use of transfer stations, (2) determine if building design features influence their attractiveness to birds, and (3) determine if other factors (e.g., season, geographic location, operational procedures) influence bird use. Twenty-nine waste transfer facilities and 4 control sites, located in 7 states (representative of various U.S. geographical regions) were studied. Avian abundance and activity was quantified at each facility and control site twice per week for one year. Nuisance bird species commonly observed using transfer stations (e.g., feeding on refuse) included gulls, European starlings, and crows. Patterns of wildlife use at transfer stations varied by season, geographic location, transfer station building design, and on-site management characteristics. Overall, this study demonstrates that wildlife use of transfer stations, particularly by nuisance birds, can be substantial.

A first step towards understanding where and when avian influenza viruses might emerge from North American waterfowl is to identify environmental and demographic determinants of infection in their populations. Laboratory studies indicate water temperature as one determinant of environmental viral persistence and we explored this hypothesis at the landscape scale. We also hypothesized that the interval apparent prevalence in ducks within a local watershed during the overwintering season would influence infection probabilities during the following breeding season within the same local watershed. Using avian influenza virus surveillance data collected from 19,965 wild waterfowl across the contiguous United States between October 2006 and September 2009 We fit Logistic regression models relating the infection status of individual birds sampled on their breeding grounds to demographic characteristics, temperature, and interval apparent prevalence during the preceding overwintering season at the local watershed scale. We found strong support for sex, age, and species differences in the probability an individual duck tested positive for avian influenza virus. In addition, we found that for every seven days the local minimum temperature fell below zero, the chance an individual would test positive for avian influenza virus increased by 5.9 percent. We also found a twelve percent increase in the chance an individual would test positive during the breeding season for every ten percent increase in the interval apparent prevalence during the prior overwintering season. These results suggest that viral deposition in water and sub-freezing temperatures during the overwintering season may act as determinants of individual level infection risk during the subsequent breeding season. Our findings have implications for future surveillance activities in waterfowl and domestic poultry populations. Further study is needed to identify how these drivers might interact with other host-specific infection determinants, such as species phylogeny, immunological status, and behavioral characteristics.

The recombinant processed enzyme has a putative sequence identical to the predicted secreted native enzyme (1,473 amino acids; 161,468 Da). This enzyme catalyzed the synthesis of a water-insoluble alpha -D-glucan from sucrose (K sub(M) 12 mM) with a broad pH optimum between 5.0 and 5.7 in the presence of calcium. Removal of calcium with dialysis resulted in lower activity in the acidic pH range, effectively shifting the pH optimum to 6.0-6.2. The enzyme was quickly inactivated at temperatures above approximately 45 degree C. The presence of dextran offered some protection from thermal inactivation between room temperature and 40 degree C but had little effect above 45 degree C. NMR and methylation analysis of the water-insoluble alpha -d-glucan revealed that it had approximately equal amounts of alpha (1 arrow right 3)-linked and alpha (1 arrow right 6)-linked d-glucopyranosyl units and a low degree of branching.

Transmission efficiency of X. fastidiosa to grapevines by H. vitripennis originating from two geographically separated populations in California (Riverside and Bakersfield) based on gender and age was evaluated. To evaluate transmission efficiencies among groups, insects were given a 96-h acquisition access period on infected grapevines and caged in groups of five on healthy grapevines for a 72-h inoculation access period. At the conclusion of tests, polymerase chain reaction determined that a mean +/- SD of 0.98 +/- 1.02 X. fastidiosa-positive H. vitripennis were present on each grapevine and that 29% of test plants were infected. Acquisition and retention of X. fastidiosa was not affected by vector origin, gender, or age. The probability that a grapevine was infected 12 wk after the inoculation access period increased with the number of X. fastidiosa-positive H. vitripennis per plant. Gender had no effect on inoculation success and main effects of insect origin and age on inoculation success were minor. Collectively, the result indicated that H. vitripennis origin, gender, and age did not affect acquisition and retention of X. fastidiosa and had only minor effects on inoculation success under laboratory conditions. Accordingly, rates of pathogen spread in the field are more likely to be affected by local biotic and abiotic factors that differentially affect H. vitripennis abundance and movement based on origin, gender, and age than inherent differences in transmission efficiencies among these groups.

The method fails to discern C. capitata from its close relative Ceratitis caetrata Munro, based on genetic distances, parsimony networks, or nucleotide diagnostic characters observed in the DNA barcode sequences. When treated as a single taxon, it is possible to discern the C. capitata + C. caetrata lineage from other Ceratitis species. Levels of intraspecific diversity vary within the genus Ceratitis and multiple copies of the mitochondrial gene are reported for Ceratitis cosyra (Walker). The DNA barcoding method based on genetic distance is compared with a molecular identification method using restriction fragment length polymorphism. The DNA barcode and restriction fragment-length polymorphism methods provide similar identification results, but the DNA sequence information is more suitable for quantitative analysis of the information.

Immature C. inclusum readily consumed cotton pollen grains that were pierced, crushed, and macerated with the mouthparts while being extraorally digested. When reared on a diet of cotton pollen alone, spiderlings survived 178% longer than those given only water (14.45 versus 5.2 d). When provided with a prey-limited diet (Five eggs of Helicoverpa zea, a favored prey) access to cotton pollen improved the likelihood of spiderlings molting to the second instar from 0 to 22%. This increased from 60 to 84% for spiderlings provided with 10 eggs plus access to pollen. Addition of cotton pollen also extended the survival of spiders fed five or 10 eggs. Supplemental consumption of pollen seems adaptive for this spider and may lead to increased survival and retention of spiders in cotton fields.

Herein, the basic principles and technological components of arthropod surveillance plans are described, as promoted in the symposium "Advancements in arthropod monitoring technology, techniques, and analysis" presented at the 58th annual meeting of the Entomological Society of America in San Diego, CA. Interdisciplinary examples of arthropod monitoring for urban, medical, and veterinary applications are reviewed. Arthropod surveillance consists of the three components: 1) sampling method, 2) trap technology, and 3) analysis technique. A sampling method consists of selecting the best device or collection technique for a specific location and sampling at the proper spatial distribution, optimal duration, and frequency to achieve the surveillance objective. Optimized sampling methods are discussed for several mosquito species (Diptera: Culicidae) and ticks (Acari: Ixodidae). The advantages and limitations of novel terrestrial and aerial insect traps, artificial pheromones and kairomones are presented for the capture of red flour beetle (Coleoptera: Tenebrionidae), small hive beetle (Coleoptera: Nitidulidae), bed bugs (Hemiptera: Cimicidae), and Culicoides (Diptera: Ceratopogonidae) respectively. After sampling, extrapolating real world population numbers from trap capture data are possible with the appropriate analysis techniques. Examples of this extrapolation and action thresholds are given for termites (Isoptera: Rhinotermitidae) and red flour beetles.

We used published and newly compiled data on inter-continentally introduced birds, mammals and plants. We found strong correlations between the latitudinal distributions occupied by species in their native and exotic ranges. However, relatively more non-native species occur at latitudes higher than those in their native ranges, and fewer occur at latitudes lower than those in their native ranges. Only a small fraction of species examined (i.e. <20% of animals and <10% of plants) have expanded their distributions in their exotic range beyond both high- and low-limits of their native latitudes. Birds, mammals and plants tended to shift their exotic ranges in similar ways. In addition, most non-native species (65-85% in different groups) have not reached the distributional extent observed in their native ranges. The possible drivers of latitudinal shifts in the exotic range may include climate change, greater biotic resistance at lower latitudes, historical limitations on ranges in native regions, and the impacts of humans on species distributions. The relatively restricted distribution of most species in their exotic range highlights the great potential of future spread of most introduced species and calls for closely monitoring their directional spread under climate change.

Airports offer one of the few land uses where reductions in wildlife abundance and habitat quality are necessary and socially acceptable, due to risk of wildlife collisions with aircraft. There are several uncertainties and limitations to establishing alternative energy production at airports, such as ensuring these facilities do not create wildlife attractants or other hazards. However, with careful planning, locating alternative energy projects at airports could help mitigate many of the challenges currently facing policy makers, developers, and conservationists.

We quantified the levels of hybridization of 180 saltcedar plants (Tamarix spp.) of varying ages that span the history of an invasion along the Green River, Utah, USA. Plants ranging in establishment dates from 1930s to 2004 were analyzed using Amplified Fragment Length Polymorphisms. All plants sampled, even those established before the Green River saltcedars were numerous, were assigned as hybrids, not as parental types that are still found in more extreme southern and northern latitudes in the USA. Our collections either did not capture the earliest parental types, parental types have failed to persist, or the first introductions to the Green River were already hybrids. In any case, it appears that hybrids have been a dominant part of this local invasion history, from establishment through invasion spread stages.

The existing literature suggests that dams homogenize the hydrologic variability of rivers. However, this might insinuate that dams affect river systems similarly despite a large gradient in natural hydrologic character. In order to evaluate patterns in dam-regulated hydrology and associated ecological relationships, a broad framework is needed. Flow classes, or groups of streams that share similar hydrology, may provide a framework to evaluate the relative effects of dam regulation on natural flow dynamics. The purpose of this study was to use a regional flow classification as the foundation for evaluating patterns of hydrologic alteration due to dams and to determine if the response of rivers to regulation was specific to different flow classes. We used the US Geological Survey (USGS) database to access discharge information for 284 unregulated and 117 regulated gage records. For each record, we calculated 44 hydrologic statistics, including the Indicators of Hydrologic Alteration. We used a sub-regional flow classification for eight states as a way to stratify unregulated and regulated streams into comparable units. In general, our results showed that dam regulation generally had stronger effects on hydrologic indices than other disturbances when models were stratified by flow class; however, the effects of urbanization, withdrawals, and fragmentation, at times, were comparable or exceeded the effects of dam regulation. In agreement with the existing literature, maximum flows, flow variability, and rise rates were lower whereas minimum flows and reversals were higher in dam regulated streams. However, the response of monthly and seasonal flows, flow predictability, and baseflows were variable depending on flow class membership. Principal components analysis showed that regulated streams occupied a larger multivariate space than unregulated streams, which suggests that dams may not homogenize all river systems, but may move them outside the bounds of normal river function. Ultimately, our results suggest that flow classes provide a suitable framework to generalize patterns in hydrologic alterations due to dam regulation.

Leaf spot control measures include the application of sterol demethylation inhibitor (DMI) fungicides. However, reduced sensitivity to DMIs has been reported recently in the Red River Valley sugar beet-growing region of North Dakota and Minnesota. Here, we report the cloning and molecular characterization of CbCyp51, which encodes the DMI target enzyme sterol P450 14 alpha -demethylase in C. beticola. CbCyp51 is a 1,632-bp intron-free gene with obvious homology to other fungal Cyp51 genes and is present as a single copy in the C. beticola genome. Five nucleotide haplotypes were identified which encoded three amino acid sequences. Protein variant 1 composed 79% of the sequenced isolates, followed by protein variant 2 that composed 18% of the sequences and a single isolate representative of protein variant 3. Because resistance to DMIs can be related to polymorphism in promoter or coding sequences, sequence diversity was assessed by sequencing >2,440 nucleotides encompassing CbCyp51 coding and flanking regions from isolates with varying EC sub(50) values (effective concentration to reduce growth by 50%) to DMI fungicides. However, no mutations or haplotypes were associated with DMI resistance or sensitivity. No evidence for alternative splicing or differential methylation of CbCyp51 was found that might explain reduced sensitivity to DMIs. However, CbCyp51 was over-expressed in isolates with high EC sub(50) values compared with isolates with low EC sub(S0) values. After exposure to tetraconazole, isolates with high EC sub(50) values responded with further induction of CbCyp51, with a positive correlation of CbCyp51 expression and tetraconazole concentration up to 2.5 mu g ml super(-1).

Merr) AN - 954667296; 16435518 AB - A multilocus sequence typing (MLST) method based on allelic variation of seven chromosomal loci was developed for characterizing genotypes (GT) within the genus Bradyrhizobium. With the method, 29 distinct multilocus GT were identified among 190 culture collection soybean strains. The occupancy of 347 nodules taken from uninoculated field-grown soybean plants also was determined. The bacteroid GT were either the same as or were closely related to GT identified among strains in the culture collection. Double-nodule occupancy estimates of 2.9% were much lower than values published based on serology. Of the 347 nodules examined, 337 and 10 were occupied by Bradyrhizobium japonicum and B. elkanii, respectively. The collection strains within the species B. japonicum and B. elkanii also were compared with Bradyrhizobium cultures from other legumes. In many cases, the observed GT varied more according to their geographic origin than by their trap hosts of isolation. In other cases, there were no apparent relationships with either the legume or geographic source. The MLST method that was developed should be a useful tool in determining the influence of geographic location, temperature, season, soil type, and host plant cultivar on the distribution of GT of Bradyrhizobium spp. JF - Molecular Plant-Microbe Interactions AU - van Berkum, P AU - Elia, P AU - Song, Q AU - Eardly, B D AD - Soybean Genomics and Improvement Laboratory, Agricultural Research Service, United States Department of Agriculture, Beltsville, MD 20705, USA, peter.vanberkum@ars.usda.gov Y1 - 2012/03// PY - 2012 DA - Mar 2012 SP - 321 EP - 330 VL - 25 IS - 3 SN - 0894-0282, 0894-0282 KW - Microbiology Abstracts B: Bacteriology; Microbiology Abstracts A: Industrial & Applied Microbiology KW - Soil types KW - Bradyrhizobium KW - Bacteroids KW - Soil temperature KW - Genotypes KW - Serology KW - Host plants KW - Glycine max KW - Nodules KW - Soybeans KW - multilocus sequence typing KW - Legumes KW - Culture collections KW - Bradyrhizobium japonicum KW - A 01360:Plant Diseases KW - J 02420:Plant Diseases UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/954667296?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Amicrobiologyb&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Molecular+Plant-Microbe+Interactions&rft.atitle=Development+and+Application+of+a+Multilocus+Sequence+Analysis+Method+for+the+Identification+of+Genotypes+Within+Genus+Bradyrhizobium+and+for+Establishing+Nodule+Occupancy+of+Soybean+%28Glycine+max+L.+Merr%29&rft.au=van+Berkum%2C+P%3BElia%2C+P%3BSong%2C+Q%3BEardly%2C+B+D&rft.aulast=van+Berkum&rft.aufirst=P&rft.date=2012-03-01&rft.volume=25&rft.issue=3&rft.spage=321&rft.isbn=&rft.btitle=&rft.title=Molecular+Plant-Microbe+Interactions&rft.issn=08940282&rft_id=info:doi/ LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2012-03-01 N1 - Last updated - 2012-04-06 N1 - SubjectsTermNotLitGenreText - Soil types; Bacteroids; Legumes; Soil temperature; Culture collections; Genotypes; Host plants; Serology; Nodules; multilocus sequence typing; Soybeans; Bradyrhizobium; Bradyrhizobium japonicum; Glycine max ER - TY - JOUR T1 - Development of an Assay for Rapid Detection and Quantification of Verticillium dahliae in Soil AN - 954652316; 16448036 AB - Verticillium dahliae is responsible for Verticillium wilt on a wide range of hosts, including strawberry, on which low soil inoculum densities can cause significant crop loss. Determination of inoculum density is currently done by soil plating but this can take 6 to 8 weeks to complete and delay the grower's ability to make planting decisions. To provide a faster means for estimating pathogen populations in the soil, a multiplexed TaqMan real-time polymerase chain reaction (PCR) assay based on the ribosomal DNA (rDNA) intergenic spacer (IGS) was developed for V. dahliae. The assay was specific for V. dahliae and included an internal control for evaluation of inhibition due to the presence of PCR inhibitors in DNA extracted from soil samples. An excellent correlation was observed in regression analysis (R super(2) = 0.96) between real-time PCR results and inoculum densities determined by soil plating in a range of field soils with pathogen densities as low as 1 to 2 microsclerotia/g of soil. Variation in copy number of the rDNA was also evaluated among isolates by SYBR Green real-time PCR amplification of the V. dahliae-specific amplicon compared with amplification of several single-copy genes and was estimated to range from approximately 24 to 73 copies per haploid genome, which translated into possible differences in results among isolates of approximately 1.8 cycle thresholds. Analysis of the variation in results of V. dahliae quantification among extractions of the same soil sample indicated that assaying four replicate DNA extractions for each field sample would provide accurate results. A TaqMan assay also was developed to help identify colonies of V. tricorpus on soil plates.

Of the 220 isolates tested, 43 (19.5%) were resistant to pyraclostrobin. Analysis of partial sequences of the cytochrome b gene (cyt b) in five pyraclostrobin-resistant (PR) and five pyraclostrobin-sensitive (PS) isolates showed that PR isolates harbored the point mutation leading to the substitution of glycine by alanine at codon position 143 in cyt b (G143A). Two pairs of allele-specific primers were designed based on this point mutation, and allele-specific polymerase chain reaction analysis with these primers showed that all 73 PR isolates (including 30 collected from decayed apple fruit) harbored the G143A mutation but PS isolates did not. Six pairs of primers were designed to analyze the presence of various introns in cyt b. There were six types (I to VI) of cyt b present in 247 isolates of B. cinerea collected from various apple-production areas in Washington State. Of the 247 isolates, 23 had type I cyt b containing all four introns (Bcbi-67/68, Bcbi-131/132, Bcbi-143/144, and Bcbi-164), 176 had type II cyt b containing three introns (Bcbi-67/68, Bcbi-131/132, and Bcbi-164), six had type III cyt b containing two introns (Bcbi-67/68 and Bcbi-131/132), one had type IV cyt b containing two introns (Bcbi-131/132 and Bcbi-164), one had type V cyt b containing only the Bcbi-131/132 intron, and 40 had type VI cyt b containing no introns. This is the first report of types III to VI cyt b present in B. cinerea. All 73 PR isolates did not carry the Bcbi-143/144 intron in cyt b. Of the 247 isolates tested, >90% did not carry the Bcbi-143/144 intron in cyt b, suggesting that B. cinerea populations from apple pose a high inherent risk for the development of resistance to QoIs because the presence of this intron in cyt b prevents the occurrence of G143A-mediated resistance. Analysis of genetic background based on three microsatellite primers showed that PR isolates originated from different lineages, and there was no correlation between cyt b types (I, II, and III) and the genetic background of the isolates; however, isolates carrying type VI cyt b might originate from the same lineage.

Materials and methods: A greenhouse study was conducted to evaluate the leaching potential and vertical distribution of total and plant-available P in a deep sandy Coastal Plain soil of the southern US fertilized with recovered P from liquid pig manure (SRP) and solid broiler litter (LRP). The recovered manure P sources were compared to commercial triple superphosphate (TSP) and raw broiler litter (BL) applied at a single rate of 170 kg P sub(2)O sub(5) ha super(-1) to 71-cm-tall soil columns with and without cotton plants. All materials were uniformly mixed into the surface 15 cm of soil in each column. All treated and control (unfertilised) soil columns were leached weekly with distilled water for 8 weeks. The water obtained after leaching the soil columns was analysed for total P. Cotton plant material was analysed for P content, and the soil columns were sectioned to determine the vertical distributions of total and plant-available P (Mehlich 3 test). Results and discussion: The vertical soil P distribution showed that most of the total and plant-available P applied with SRP, LRP, and BL materials remained within the top 15-cm of the soil columns, where materials were initially applied. The significant increase of both total and soil available P within 15-22.5 cm of soil columns treated with TSP indicated translocation and potential leaching of P applied as TSP. In the short term of this study (8 weeks), the soil leaching potential of both LRP and SRP was lower than the more water-soluble commercial TSP fertilizer. Conclusions: The use of recovered P could minimize manure P losses into the environment from confined animal production and provide a recycled P source for use as crop fertilizer.

In this study, impacts of projected CC on dryland crop rotations of wheat-fallow (WF), wheat-corn-fallow (WCF), and wheat-corn-millet (WCM) in the U.S. Central Great Plains (Akron, Colorado) were simulated using the CERES V4.0 crop modules in RZWQM2. The CC scenarios for CO sub(2), temperature and precipitation were based on a synthesis of Intergovernmental Panel on Climate Change (IPCC 2007) projections for Colorado. The CC for years 2025, 2050, 2075, and 2100 (CC projection years) were super-imposed on measured baseline climate data for 15-17 years collected during the long-term WF and WCF (1992-2008), and WCM (1994-2008) experiments at the location to provide inter-annual variability. For all the CC projection years, a decline in simulated wheat yield and an increase in actual transpiration were observed, but compared to the baseline these changes were not significant (p>0.05) in all cases but one. However, corn and proso millet yields in all rotations and projection years declined significantly (p<0.05), which resulted in decreased transpiration. Overall, the projected negative effects of rising temperatures on crop production dominated over any positive impacts of atmospheric CO sub(2) increases in these dryland cropping systems. Simulated adaptation via changes in planting dates did not mitigate the yield losses of the crops significantly. However, the no-tillage maintained higher wheat yields than the conventional tillage in the WF rotation to year 2075. Possible effects of historical CO sub(2) increases during the past century (from 300 to 380 ppm) on crop yields were also simulated using 96 years of measured climate data (1912-2008) at the location. On average the CO sub(2) increase enhanced wheat yields by about 30%, and millet yields by about 17%, with no significant changes in corn yields.

The radiation use efficiency (RUE), when derived in an environment with non-limiting soil water and soil nutrients, provides one metric of relative productivity. The objective of this study was to compare giant Miscanthus to available switchgrass cultivars, using established methods to calculate RUE of the two species at two disparate sites. Measurements of fraction intercepted photosynthetically active radiation (PAR) and dry matter were taken on plots at Elsberry, MO (Miscanthus and the switchgrass cultivars Alamo, Kanlow, and Cave-in-Rock) and at Gustine, TX (Miscanthus and Alamo switchgrass, irrigated with dairy wastewater and a non-irrigated control). In MO, Miscanthus mean RUE (3.71) was less than Alamo switchgrass mean RUE (4.30). In TX under irrigation, Miscanthus mean RUE was 2.24 and Alamo switchgrass mean RUE was 3.20. In MO, the more northern lowland switchgrass cultivar, Kanlow, showed similar mean RUE (3.70) as Miscanthus. In MO, the northern upland cultivar Cave-in-Rock had a mean RUE (3.17) that was only 85% of that for Miscanthus at MO. Stress (water and nutrients) had a greater effect on Miscanthus RUE than on switchgrass RUE in TX. These results provide realistic RUE values for simulating these important biofuel grasses in diverse environmental conditions.

A better understanding of the changes in composition with development along the stalk and with crop development will maximize the usage of sugarcane for this purpose. Two experiments were designed to elucidate internode composition changes during the growing season. In experiment 1, an internode of stalks of 5 modern cultivars were marked at the start of elongation, and then sampled every 1 to 2 weeks from July until October. Sugars were extracted and assayed, and a sequential detergent method was used to estimate hemicellulose, cellulose, and lignin contents. In experiment 2, internodes 1, 3, 5, 7, 9, and 11 down the stalk were sampled in late July (grand growth) and late September (ripening). Internode length, fresh weight, dry weight, water content, and sugar contents were determined as well as cell wall composition. Both experiments were repeated in 2 years. As internodes elongated, total sugar increased, and hemicellulose decreased as a proportion of neutral detergent fiber, while cellulose and lignin increased. After elongation, sucrose and lignin increased, and cellulose content decreased with internode age. The variability in cell wall composition among the five cultivars suggests that selection for desirable composition may be possible. In Experiment 2, hemicellulose contents were lower, and lignin and ash contents were higher at ripening than during grand growth. Delaying sugarcane harvest to maximize sucrose content may decrease bagasse suitability for cellulosic ethanol production because of the increased lignin content.

The reactions of races to the differential wheat lines follow the classic gene-for gene system for host-pathogen interactions. The pathogens are closely related and resistance to both diseases in wheat is controlled by the same genes. To better define pathogenic races, six additional wheat lines containing the genes Bt11 through Bt15 and a wheat line with a resistance factor designated as Btp were added to the set of 10 differentials and tested with all named U.S. races of common bunt and dwarf bunt. In addition, new isolates of dwarf bunt, and common bunt from hybrids and field collections, were tested with all 16 differentials for race identification. Six new races of T. caries, five new races of T. foetida, and two new races of T. contraversa were identified. Races of common bunt virulent to Bt8 or Bt12, and dwarf bunt races virulent to the combinations of Bt11 and Bt12, and Bt8, Bt9, Bt10, Bt11, and Bt12, were identified for the first time. Comparison of the reactions of the common bunt races with the Bt14 and Bt15 differentials grown in different environments after initial infection showed that these genes are temperature sensitive, indicating they should be excluded from the set of differential lines to avoid ambiguity in determining virulent or avirulent reactions. In the previous list of bunt races, there were races that had the same reaction to the set of 10 differentials but were designated as different races. These races were not differentiated further with the six additional differentials, indicating that the duplicate races should be dropped from the list of pathogenic races. The new races of common bunt and dwarf bunt identified have unique patterns of virulence that allow specific targeting and elucidation of bunt resistance genes in wheat and will aid the development of bunt-resistant wheat cultivars.

In this study, the spread of crown gall via contaminated tools and the efficacy of several disinfectants against A. tumefaciens were demonstrated. The cationic surfactants benzalkonium chloride (BC), cetyltrimethylammonium bromide (CTAB), and Physan 20 eliminated 100% of the A. tumefaciens population in water suspensions treated at 7, 5, and 2 ppm, respectively. Sodium hypochlorite eliminated 100% of the A. tumefaciens population at 0.5 ppm. Sodium hypochlorite efficacy, however, was reduced by 64% in the presence of total solids (0.7 g/ml) which are commonly found in field situations. At similar concentrations of total solids, the efficacy of cationic surfactants decreased, on average, by only 13%. The minimum effective treatment needed to eliminate A. tumefaciens on infested scalpels was a 5-s exposure to BC or CTAB at 5,000 ppm (0.5%). Infested scalpels treated with BC or CTAB at less than 5,000 ppm caused gall formation in 14 plus or minus 7% of cuts made on Datura stramonium stems. This was significantly less than the tumor incidence (100%) in cuts made with inoculated blades not treated BC or CTAB.

T. apicalis, a pest of carrot in northern and central Europe, including Sweden, can cause as much as 100% crop loss and is associated with "Ca. L. solanacearum" (1-4). Symptoms on affected plants include leaf curling, yellow and purple discoloration of leaves, stunted growth of shoots and roots, and proliferation of secondary roots (3). Carrot plant and psyllid samples were collected from fields in the province of Halland. Total DNA was extracted from petiole and root tissues of 33 symptomatic and 16 asymptomatic plants (cvs. Nevis and Florida), with the cetyltrimethylammonium bromide (CTAB) buffer extraction method (2,3). DNA was also extracted from 155 psyllids (3). DNA samples were tested by PCR using primer pairs OA2/OI2c (5'-GCGCTTATT TTTAATAGGAGCGGCA-3'/5'-GCCTCGCGACTTCGCAACCCAT-3') and CL514F/R (5'-CTCTAAGATTTCGGTTGGTT-3'/5'-TATATCTATCGT TGCACCAG-3'), to amplify a portion of 16S rDNA and rplJ/rplL ribosomal protein genes, respectively, of "Ca. L. solanacearum" (2,3). A 1,168-bp 16S rDNA fragment was detected in the DNA from all 33 symptomatic and two asymptomatic plants, and a 668-bp rplJ/rplL fragment was amplified from the DNA of all 33 symptomatic and four asymptomatic plants, indicating the presence of liberibacter. DNA from 23 and 49 psyllid samples yielded similar amplicons with OA2/OI2c and CL514F/R primer pairs, respectively. Amplicons from the DNA of four carrot roots and three T. apicalis with each primer pair were cloned (pCR2.1-TOPO; Invitrogen, Carlsbad, CA) and three clones of each of the 14 amplicons were sequenced (MCLAB, San Francisco, CA). BLAST analysis of the 16S rDNA consensus sequences from carrot (GenBank Accession No. JN863095) and T. apicalis (GenBank Accession No. NJ863096) showed 100% identity to those of "Ca. L. solanacearum" previously amplified from carrot (GU373048 and GU373049) and T. apicalis (GU477254 and GU477255) from Finland (2,3). The rplJ/rplL consensus sequences from carrot (GenBank Accession No. JN863093) and T. apicalis (GenBank Accession No. JN863094) were 99% identical to the sequences of rplJ/rplL "Ca. L. solanacearum" ribosomal protein gene from carrots in Finland (GU373050 and GU373051). To our knowledge, this is the first report of "Ca. L. solanacearum" associated with carrot and T. apicalis in Sweden. The disease associated with this bacterium caused millions of dollars in losses to potato and several other solanaceous crops in North and Central America and New Zealand (1). This plant pathogen is also associated with significant economic damage to carrot crops observed in Finland (2,3).

Symptoms included brown spots, streaks, and stripes in and near the vascular tissue, typical of ZC (1). Symptoms were observed in cvs. Alturas, Russet Norkotah, Pike, Ranger Russet, Umatilla Russet, and Russet Burbank. Foliar symptoms on plants that produced symptomatic tubers included purple discoloration in upper leaves, leaf rolling, axial bud elongation, chlorosis, leaf scorch, and wilt. Tissue was taken from two symptomatic tubers each of cvs. Alturas and Russet Norkotah, three tubers of cv. Umatilla Russet, and one tuber of cv. Pike. These tubers were tested by PCR for "Candidatus Liberibacter solanacearum", an unculturable alphaproteobacterium associated with ZC (1, 4). Primers specific for the 16S rDNA were CLipoF (4) and OI2c (3), and primers OMB 1482f and 2086r were specific for the outer membrane protein (2). All of these samples, except one Umatilla tuber, were positive for the bacterium. The 16S rDNA and OMB amplicons from one symptomatic tuber each of Alturas (from Washington) and Pike (from Oregon) were cloned and three clones of each were sequenced. BLAST analysis of the consensus sequences confirmed "Ca. L. solanacearum". The 16S sequences (1,071 bp) from the two tubers were identical and showed 99 to 100% identity to a number of 16S rDNA sequences of "Ca. L. solanaceaum" in GenBank (e.g., Accession Nos. HM246509 and FJ957897). The 16S rDNA sequences were deposited in GenBank as Accession Nos. JN848751 and JN848753. Consensus sequences of the two OMB clones (605 bp; deposited in GenBank as Accession Nos. JN848752 and JN848754) were identical and showed 97% identity to the two "Ca. L. solanacearum" OMB sequences in GenBank (Accession Nos. CP002371 and FJ914617). Potato psyllids (Bactericera cockerelli Sulc), the vector of "Ca. L. solanacearum", were present in ZC-affected fields in Oregon and Washington and the bacterium was confirmed by PCR in 5 to 10% of 128 adult psyllids collected from two fields. On the basis of foliar and tuber symptoms, specific PCR amplification with two primer pairs, sequence analyses, and the presence of Liberibacter-infected potato psyllids, ZC and "Ca. L. solanacearum" are present in potatoes in Oregon and Washington State. Washington and Oregon together grow similar to 80,000 ha of potatoes. ZC has caused significant economic damage to potatoes in Texas, Mexico, Central America, and New Zealand (1). Therefore, ZC may pose a risk to agriculture in Oregon, Washington, and neighboring states. However, the potential for development of widespread and serious disease will depend upon the arrival time and number of infective potato psyllids entering the region.

Moench) after harvest. Three cultivars of sorghum were harvested at 90, 115, and 140 days after planting. Stripped and topped stalks were divided into four treatments: whole stalks, 20- or 40-cm billets, and chopped. Samples were placed in individual plastic bins and stored outside in a shade tent. At 0, 1, 2, and 4 days after harvest, subsamples were removed from each bin and the juice expressed. Juice was analyzed for degree Brix (percent total dissolved solids on a w/w basis) and the simple sugars glucose, fructose, and sucrose. In most of the treatments, juice degree Brix decreased slightly or was unchanged during storage. Sucrose decreased in all treatments, while glucose and fructose increased in the whole stalk, 20-cm billet, and 40-cm billet treatments. In those treatments, total sugar was little changed over the 4-day storage period. In chopped sorghum, decreases in glucose were significant after 1 day of storage. Glucose decreased to near 0 mg mL super(-1) by 2 days after harvest, while the decrease in fructose was not as great. The Pearson correlation between total sugar and degree Brix using day 0 means (non-deteriorated juice) was r=0.964 (n=32, rho <0.001). The correlation between total sugar and degree Brix using the shredded sample means, which included deteriorated juice, was r=0.411 (n=24, rho less than or equal to 0.046). Juice degree Brix should not be used to evaluate juice for deterioration. We conclude that whole stalk and billet harvesting are superior to harvesting by forage harvester since forage-harvested sorghum would have to be processed within hours to maintain the sugars.

In pINTRS, the gene encoding glutamate decarboxylase, gadB, was flanked by DNA fragments homologous to a S. thermophilus pseudogene to allow for integration at a non-essential locus on the chromosome. Screening techniques confirmed the insertion of gadB with either its endogenous promoter or the S. thermophilus P2201 promoter, resulting in the generation of recombinant strains, ST128/gadB or ST128/P2201-gadB. Following the integration event unwanted plasmid DNA, specifically the erythromycin resistance gene, was eliminated from the recombinant strains. Based on the production of GABA, activities of GAD for ST128/gadB and ST128/P2201-gadB were 30.6 plus or minus 6 and 27.9 plus or minus 7.2 mu M/mg dry cell wt, respectively.

Cover crop-based, organic rotational no-till grain production is one approach to accomplish these goals. This approach is becoming more viable with advancements in a system for planting crops into cover crop residue flattened by a roller-crimper. However, inability to consistently control weeds, particularly perennial weeds, is a major constraint. Cover crop biomass can be increased by manipulating seeding rate, timing of planting and fertility to achieve levels (>8000 kg ha-1) necessary for suppressing summer annual weeds. However, while cover crops are multi-functional tools, when enhancing performance for a given function there are trade-off with other functions. While cover crop management is required for optimal system performance, integration into a crop rotation becomes a critical challenge to the overall success of the production system. Further, high levels of cover crop biomass can constrain crop establishment by reducing optimal seed placement, creating suitable habitat for seed- and seedling-feeding herbivores, and impeding placement of supplemental fertilizers. Multi-institutional and -disciplinary teams have been working in the mid-Atlantic region to address system constraints and management trade-off challenges. Here, we report on past and current research on cover crop-based organic rotational no-till grain production conducted in the mid-Atlantic region.

Both species, introduced from Europe in the 1800s, are listed as noxious weeds or banned invasive species by the USDA-Natural Resource Conservation Service. Observations by C. Southby, a local naturalist, over several years at a meadow populated by pale swallow-won in Powder Mill Park, Monroe County, NY, revealed a gradual disappearance of pale swallow-wort with restoration of native grasses and some dicotyledonous plant species, in a 6.7-m-diameter area. Diseased swallow-wort plants had extensive yellowing and wilting of foliage, likely due to splitting of the basal stem, with white mycelium throughout the stem and crown; small, reddish brown sclerotia were evident, but roots were not affected. Stem tissue sections from 20 symptomatic plants were vacuum infiltrated with 2% NaOCl for 20 min, then plated onto malt yeast agar and potato dextrose agar amended with 60 mg/liter of penicillin and 80 mg/liter of streptomycin, resulting in development of fast-growing, white mycelium which then formed numerous, irregularly shaped (2 to 4 mm diameter), reddish brown sclerotia at the plate edges. Two individual cultures were identified as S. rolfsii (1) based on size, shape, and color of the sclerotia and presence of characteristic clamp connections in the mycelium. The isolate was suspected to be S. rolfsii var. delphinii due to the reported inability of S. rolfsii to persist in regions with extremely low winter temperatures (4), but molecular data showed otherwise. Sequences of the 18S gene (GenBank JN543690), internal transcribed spacer region (JN543691), and 28S gene (JN543692) of the ribosomal DNA identified the isolate, VrNY, as S. rolfsii (2,3). Pathogenicity tests were conducted with individual 2-month-old seedlings of V. rossicum and V. nigrum grown in steam-sterilized Metromix 360 in SC10 polypropylene conetainers in a growth chamber with a diurnal cycle of 25/20 degree C, a photoperiod of 14-h light/10-h dark, and fertilized at 3 week intervals. Two independent replications of 12 plants of each species were each inoculated at the stem base with a 4-mm-diameter mycelial agar plug from the growing edge of a colonized plate. The agar plug was held in place with 5 g of sterile sand. Control plants (12 of each species per replication) were treated with sterile agar plugs. Plants for each treatment were placed within a clear plastic bag to maintain 90% relative humidity for 72 h, and then removed from the bags. Disease symptoms developed over 21 days, with >90% of inoculated plants showing symptoms within 2 weeks. Control plants were symptomless. Incidence of mortality was 66 and 60% for V. rossicum and V. nigrum, respectively, by 3 weeks. The fungus reisolated from diseased stem and crown tissue produced characteristic mycelium with irregular sclerotia, consistent with those of S. rolfsii. Since spread of this fungus is based on movement of soilborne sclerotia, this isolate may offer potential as a bio-herbicide for control of swallow-wort in natural ecosystems if the isolate can be demonstrated to have a host range restricted to this invasive weed.

Pesticide leaching through soil has been identified as a major cause for the occurrence of these chemicals in surface and groundwater. We developed matrix-based fertilizers (MBFs) that have been shown to reduce N and P leaching. We tested the efficacy of the ionic bonds in the MBFs to reduce 2,4-dichlorophenoxyacetic acid (2,4-D), metolachlor, thiophanate methyl, carbaryl, diazinon, and malathion leaching in soil columns. After 7 days 2,4-D, thiophanate methyl, carbaryl, and malathion did not leach in sufficient quantities to determine if the MBF fertilizers reduced leaching compared with the control and the slow-release fertilizer Polyon registered . The MBF fertilizers leached from five to 30 times less metolachlor than the control and Polyon registered treatment. Treatments with MBF fertilizers leached from two to 72 times less diazinon than the control treatment. The MBF fertilizer treatment leached from eight to 268 less diazinon than columns receiving Polyon registered . The MBF formulations allow compounds with both anionic and cationic charges to bind with the Al(SO sub(4)) sub(3) 3H sub(2)O and/or Fe sub(2)(SO sub(4)) sub(3) 3H sub(2)O-lignin-cellulose matrix. When pesticides are added to the soil amended with matrix-based fertilizers, the ion exchange matrix will likely bind the metolachlor and diazinon to the Al(SO sub(4)) sub(3) 3H sub(2)O and/or Fe sub(2)(SO sub(4)) sub(3) 3H sub(2)O-starch-cellulose-lignin matrix thereby substantially reducing leaching. The MBFs could be used to limit both nutrients and pesticide leaching from agricultural fields.

Sources of highly active, inexpensive, renewable flocculants are needed to replace synthetic flocculants. High kaolin flocculant activity was documented for bovine blood (BB) and blood plasma with several anticoagulant treatments. BB serum also had high flocculant activity. To address the hypothesis that some blood proteins have strong flocculating activity, the BB proteins were separated by SEC. Then, the major proteins of the flocculant-active fractions were separated by SDS-PAGE. Identity of the major protein components was determined by tryptic digestion and peptide analysis by MALDI TOF MS. The sequence of selected peptides was confirmed using TOF/TOF-MS/MS fragmentation. Hemoglobin dimer (subunits alpha and beta ) was identified as the major protein component of the active fraction in BB; its high flocculation activity was confirmed by testing a commercial sample of hemoglobin. In the same manner, three proteins from blood plasma (fibrinogen, gamma -globulin, alpha -2-macroglobulin) were found to be highly active flocculants, but bovine serum albumin, alpha -globulin, and beta -globulin were not flocculants. On a mass basis, hemoglobin, gamma -globulin, alpha -2-macroglobulin were as effective as anionic polyacrylamide (PAM), a widely used synthetic flocculant.

None of the AMP genes tested was significantly upregulated at 2h post-infection. Hepcidin was the only one that was significantly (P<0.05) upregulated at 4, 6 and 12h post-infection. At 24 and 48h post-infection, four AMPs (hepcidin, NK-lysin type 1, NK-lysin type 3 and cathepsin D) were significantly (P <0.05) upregulated. Among all the AMPs that were significantly upregulated at different time points, hepcidin at 4, 6 and 12h post-infection was upregulated the most. When catfish were injected with different doses of E. ictaluri, all lethal doses were able to induce significant (P <0.05) upregulation of hepcidin in the posterior kidney, whereas sublethal doses failed to induce any significant upregulation of hepcidin. In vitro growth studies revealed that the presence of synthetic hepcidin peptide at a concentration of 16 mu m or higher significantly inhibited the cell proliferation of E. ictaluri. Taken together, our results suggest that hepcidin might play an important role in the channel catfish defence against E. ictaluri infection.

Reaction temperature and time were varied between 160 and 200 degree C and 5-20 min, respectively, using a response surface experimental design. The liquid fraction was analyzed for soluble carbohydrates and furan aldehydes. The solid fraction was analyzed for structural carbohydrates and Klason lignin. Pretreatment conditions were evaluated based on enzymatic extraction of glucose and xylose and conversion to ethanol using a simultaneous saccharification and fermentation scheme. SSF experiments were conducted with the washed pretreated biomass. The severity of the pretreatment should be sufficient to drive enzymatic digestion and ethanol yields, however, sugars losses and especially sugar conversion into furans needs to be minimized. As expected, furfural production increased with pretreatment severity and specifically xylose release. However, provided that the severity was kept below a general severity factor of 4.0, production of furfural was below an inhibitory concentration and carbohydrate contents were preserved in the pretreated whole hydrolysate. There were significant interactions between time and temperature for all the responses except cellulose digestion. The models were highly predictive for cellulose digestibility (R super(2) = 0.8861) and for ethanol production (R super(2) = 0.9581), but less so for xylose extraction. Both cellulose digestion and ethanol production increased with severity, however, high levels of furfural generated under more severe pretreatment conditions favor lower severity pretreatments. The optimal pretreatment condition that gave the highest conversion yield of ethanol, while minimizing furfural production, was judged to be 190 degree C and 17.2 min. The whole hydrolysate was also converted to ethanol using SSF. To reduce the concentration of inhibitors, the liquid fraction was conditioned prior to fermentation by removing inhibitory chemicals using the fungus Coniochaeta ligniaria.

Methods and Results: The aluminium pipes in the sprinkler irrigation system were outfitted with coupons that were extracted before each of the 2-h long irrigations carried out with weekly intervals. Water from the creek water and sprinklers, residual water from the previous irrigation and biofilms on the coupons were analysed for E. coli. High E. coli concentrations in water remaining in irrigation pipes between irrigation events were indicative of E. coli growth. In two of the four irrigations, the probability of the sample source, (creek vs sprinkler), being a noninfluential factor, was only 0.14, that is, source was an important factor. The population of bacteria associated with the biofilm on pipe walls was estimated to be larger than that in water in pipes in the first three irrigation events and comparable to one in the fourth event. Conclusion: Biofilm-associated E. coli can affect microbial quality of irrigation water and, therefore, should not be neglected when estimating bacterial mass balances for irrigation systems. Significance and Impact of the Study: This work is the first peer-reviewed report on the impact of biofilms on microbial quality of irrigation waters. Flushing of the irrigation system may be a useful management practice to decrease the risk of microbial contamination of produce. Because microbial water quality can be substantially modified while water is transported in an irrigation system, it becomes imperative to monitor water quality at fields, rather than just at the intake.

Managing crop irrigation under conditions where the water need cannot be fully met represents the future of irrigation in many areas. On the southern high plains of Texas there is interest among producers to reduce the amount of water applied to cotton. In this study, a producer's efforts to reduce water application to a cotton crop were assessed in terms of a comparison between evapotranspiration, rainfall, and irrigation that is widely used in the region. The producer was able to reduce water application to meet intended reductions relative to the evapotranspiration estimates but, depending on the method used for calculating the crop water need, he tended to over water the crop in two out of three intended deficit irrigation regimes. Analysis of continuously monitored canopy temperatures provided verification of over-irrigation. Continuously monitored canopy temperature is proposed as a useful adjunct to evapotranspiration approaches to deficit irrigation management.

Nevertheless, few studies have documented the quantity and quality of exported organic matter over multiple years and under a range of conditions that includes both droughts and hurricanes. This study quantifies the export of coarse particulate organic matter (CPOM, > 12.7 mm), over 18 y in two headwater streams in north-east Puerto Rico. Daily exports ranged from 0 to over 170 g ha super(-1) d super(-1) and averaged 7.39 g ha super(-1) d-1, with similar amounts coming from leaves (3.5 g ha super(-1) d super(-1)) and wood (3.2 g ha super(-1) d super(-1)). Export of coarse particulate organic carbon was 3.0 g ha super(-1) d super(-1) which constitutes only 1.32% of carbon exports. Most litter falling into the streams was processed in place as only 2.3% of the leaf litter falling directly into these perennial channels was exported as CPOM. On average, 6 wk y super(-1) had no exports while events transporting more than 10 g ha super(-1) d super(-1) occurred every 2.8 mo. Instead of a single annual pulse as observed in deciduous systems, there were annual peaks in CPOM exports during May and September and less export during the drier period from December to February. Ratios of C:N in the exported material were highest in the driest month and lowest during rainy months, while leaf fluxes for nitrogen, phosphorus and calcium were highest in rainy months and lowest during February. Although median daily exports and exports during low- and base-flow periods were similar before and after Hugo, after 16 y exports during moderate- and high-flow periods were still less than those in the 2 y prior to the hurricane. Our observations indicate a system with high rates of internal processing that quickly returns to median daily conditions following hurricanes but requires several decades for storm-flow exports to return to pre-disturbance conditions and indicates that the long-term pattern of CPOM export is associated with the level of maturity of watershed vegetation.

These enterotoxins have two separate but related biological activities. They cause gastroenteritis, and they function as superantigens that activate large numbers of T cells. In the current study, we demonstrate that short-term ex vivo exposure of primary naive CD4+ T-cells to SEA induces differential expression of the T cell surface receptor CD154 in a time- and dose-dependent manner. In addition, we show that SEA induces higher CD154 protein expression and higher splenocyte cell proliferation compared with SEB.

The specificity of this assay was evaluated using 390 bacterial strains including V. parahaemolyticus, and other strains belonging to Vibrio and non-Vibrio species. The real time PCR assay unambiguously distinguished V. parahaemolyticus with a detection sensitivity of 4.8 fg per PCR with purified genomic DNA or 1 CFU per reaction by counting V. parahaemolyticus colonies. The assays of avoiding interference demonstrated that, even in the presence of 2.1 mu g genomic DNA or 10 super(7) CFU background bacteria, V. parahaemolyticus could still be accurately detected. In addition, the IAC was used to indicate false-negative results, and lower than 94 copies of IAC per reaction had no influence on the detection limit. Ninety-six seafood samples were tested, of which 58 (60.4%) were positive, including 3 false negative results. Consequently, the real time PCR assay is effective for the rapid detection of V. parahaemotyticus contaminants in seafood.

Wind tunnel experiments and field monitoring were used to determine the effect VEB had on wind flow patterns within a swine facility. Particle and odorous compound concentrations were monitored before and after the VEB. Wind tunnel experiments indicated that building orientation had about the same impact on air flow patterns as the combined buildings and VEB. Field monitoring studies revealed that air flow patterns at a swine facility were dynamic showing intense instability during the heat of the day, but stable air in the evening hours indicating that air during the day was controlled by vertical movement into the atmosphere while in the evening air patterns show a collapse mostly horizontal movement. Total particle counts before and after the vegetative buffer were reduced by over 40% and odorous compound concentrations for volatile fatty acids, phenol and indole compounds were reduced by 40-60%. Plant material taken from trees in the vegetative buffer showed no significant loading gradients between materials facing the swine facility and those opposite the swine facility. There were significantly higher loadings of odorous VFAs, phenolic, and indole compounds on plant material for samples taken from 2.7m compared to samples taken from either 0.6 or 1.3m indicating that vertical transport was major transport mechanism for odor at the swine facility.

With only residual fertility in the soil and no irrigation, this test compared biomass yields of eight grasses under low-input production: L 79-1002 energycane (Saccharum hyb.), Merkeron and N51 napiergrass (Pennisetum purpureum Schum.), three clones of giant reed (Arundo donax L.), and two switchgrass (Panicum virgatum L.) lines. For the first 2 years napiergrass maintained dry matter (DM) yields over 25 Mg DM ha super(-1) year super(-1), and energycane yielded over 20 Mg DM ha super(-1)year super(-1) for 3 years. Switchgrass yields were lower (8.6 Mg DM ha super(-1) year super(-1) average of 4 years), but the biomass contained less moisture at harvest than the other, larger-stemmed grasses. Switchgrass biomass also had the lowest concentrations of N, K, and ash. Average yields of giant reeds were also low (6.4 Mg DM ha super(-1) year super(-1)), while ash and N concentrations were relatively high compared with switchgrass and energycane. In 4 years of production, energycane and napiergrass removed between 269 and 386 kg N ha super(-1) and 830-1,159 kg K ha super(-1), while the other grasses removed significantly less of these nutrients. Giant reed removed 126 kg N ha super(-1) and 193 kg K ha super(-1), and switchgrass removed 83 kg N ha super(-1) and 140 kg K ha super(-1). In Southeast USA, it is possible to produce biomass from perennial grasses with minimal inputs but the high nutrient removal rates of some species suggest that it may not be sustainable for long periods of time.

To find region- and variety-specific values of K(c) from field-measured ET(c) values, the equation is inverted to: K(c) = ET(c)/ET(r). Forms of the Penman-Monteith (PM) formula for calculation of reference alfalfa or grass evapotranspiration (ET(r) and ET(o), respectively) were promulgated by ASCE in 1990, FAO in 1998, and ASCE in 2005. The PM formulations are sensitive to climatic conditions, producing estimates of ET(r) and ET(o) that are more or less close to measured values depending on regional climate, and yielding values of K(c) that vary from region to region and so are not transferra-ble. Theoretical shortcomings may be the basis of some of these problems, including the explicit nature of the calculation, which relies on the implied assumptioh That canopy and air Temperatures are equal. We examined The ET(r) estimation of two surface energy balance formulations that stipulated different air and canopy temperatures: a two-layer (soil and canopy) approach, and a one-layer (big leaf) approach that included soil heat flux. Since canopy temperature is implicit in these formulations, they must be solved iteratively. Iterative solutions of ET(r) were compared with the ASCE PM formulation and against lysimeter-measured ET(r) All three methods of ET(r) estimation produced ET values that compared very well with field-measured ET for alfalfa grown under reference ET conditions. Errors may occur with any of the three approaches to ET(r) estimation when stomatal resistance changes due to weather conditions; thus, assumptions of constant daytime and nighttime surface resistances cause mis-estimation of surface energy fluxes. It appears that a surface resistance value of 200 s m(-1) at night for alfalfa grown under reference ET conditions is too large. It also appears that assuming constant daytime surface resistance of 30 s m(-1) is probably not ideal, and that presenting daytime surface resistance as a Junction of vapor pressure deficit might improve ET(r) calculation.

The ability of ZEN to move from contaminated crops to surface waters has been demonstrated previously. This article reports the development and application of a method for the measurement of ZEN in surface waters from the central part of Illinois, USA. The method uses a cleanup procedure based on tandem reverse-phase disks and immunoaffinity columns, separation by liquid chromatography and detection by a combination of absorbance and fluorescence. ZEN was frequently found in samples of waters from lakes, streams and a field ditch. Although the frequency of detection was high (32% above the limit of detection, 0.4 ng L super(-1)), the levels found were low, with the highest sample having 5.7 ng L super(-1). Therefore, although fungi can contribute to the exposure to environmental estrogens, the contribution from zearalenone in water is likely small.

Estimators for roundwood receipts totals comprised several types: simple random sample, ratio, stratified sample, and combined ratio. Two stratification methods were examined: the Dalenius-Hodges (DH) square root of the frequency method and a cluster analysis method. Three candidate sizes for the number of groups were selected from the cluster analysis and subsequently used in the DH stratification as well. Relative efficiency improved when the number of groups increased and when using a ratio estimator, particularly a combined ratio. The two stratification methods performed similarly. Neither the DH method nor the cluster analysis method performed better than the other. Six bound sizes (1%, 5%, 10%, 15%, 20%, and 25%) were considered for deriving samples sizes for the total volume of roundwood receipts. The minimum achievable bound size was found to be 10% of the total receipts volume for the DH method using a two-group stratification. This was true for both the stratified and combined ratio estimators. In addition, for the stratified and combined ratio estimators, only the DH method stratifications were able to reach a 15% bound on the total (six of the 12 stratified estimators). These results demonstrate that the utilized classification methods are compatible with stratified totals estimators and can provide users with the opportunity to develop viable sampling procedures as opposed to complete mill censuses.Original Abstract: Les donnees de l'etude de 2001 sur les produits de transformation du bois en Georgie ont ete analysees pour identifier de nouvelles methodes de stratification des usines et pour trouver des estimateurs d'echantillonnage appropries. Quatre estimateurs du volume total des arrivages de bois rond ont ete consideres : l'echantillon aleatoire simple, le rapport, l'echantillon stratifie et le rapport combine. Deux methodes de stratification ont ete examinees : la methode de la racine carree cumulee de la frequence de Dalenius-Hodges (DH) et une methode d'analyse par grappes. Trois tailles candidates pour le nombre de grappes ont ete selectionnees a partir de l'analyse par grappes et ensuite elles ont aussi ete utilisees dans la methode de stratification de DH. L'efficacite relative s'est amelioree avec l'augmentation du nombre de grappes et l'utilisation d'un estimateur de rapport, en particulier un rapport combine. Les deux methodes de stratification avaient une performance similaire : la methode de stratification de DH et la methode d'analyse par grappes etaient equivalentes. Six tailles limites (1%, 5%, 10%, 15%, 20%, et 25%) ont ete considerees pour calculer la taille des echantillons pour le volume total des arrivages de bois rond. La taille minimale realisable etait de 10% du volume total pour la methode de DH basee sur une stratification en deux groupes. Cette taille minimale etait valable a la fois pour l'estimateur stratifie et pour l'estimateur par rapport combine. En outre, pour l'estimateur stratifie et l'estimateur par rapport combine, seule la methode de stratification de DH a pu atteindre la limite de 15% du volume total (six des 12 estimateurs stratifies). Ces resultats demontrent que les methodes de classification utilisees sont compatibles avec les estimateurs des totaux stratifies et peuvent fournir aux utilisateurs l'occasion de developper des methodes d'echantillonnage viables par opposition au recensement complet des usines.

This study was conducted in the Pacific Northwest (PNW) region of United States to evaluate the effects of deficit irrigation (DI) and rates of pre-plant and in-season N applications on Ranger Russet and Umatilla Russet cultivars. In 2004, with Ranger Russet only, DI with 20% lower total irrigation for the entire growing period resulted in 28% tuber yield reduction compared to that of plants irrigated to replenishment full evapotranspiration (ET), i.e., full irrigation (FI). A subsequent study in 2006 and 2007 with DI (14% to 17% deficit) resulted in tuber yield reduction of 7% to 10% in both cultivars compared to full ET irrigation. Yield reduction in DI was generally attributed to reduction in large weight tubers, >0.227 kg/tuber, in both cultivars across three years. Petiole NO3-N concentrations were greater in plants grown under DI as compared to those of plants in full ET irrigation across all years and cultivars, particularly during tuber maturation stage. This is an important consideration as increased N availability during the late growing season adversely affects tuber quality. Petiole NO3-N concentrations increased with increased in-season N rates. In 2007, 112 kg.ha-1 in-season N resulted in petiole NO3-N concentrations below desirable concentrations across most of the growing season in both cultivars. This, in turn, contributed to a significant reduction in tuber yield as compared to the 224 kg.ha-1 in-season N rate. Continuous DI with 14% to 20% reduction in water as compared to irrigation to replenish full ET, begun three to four weeks after seedling emergence, had significant negative effects on tuber yields of both cultivars in high-production irrigated growing conditions. Application of N up to 112 kg ha-1 as pre-plant soil applied plus 224 kg ha-1 of in-season fertigation in five applications at two-week intervals beginning four weeks after seedling emergence appears to be adequate to support high yields of high-quality tubers.

Acid values (AVs) and kinematic viscosities of the oils were measured over 28 days on oils stored at 85 degree C. As expected, the AVs and viscosities increased with time and the HO SBO demonstrated similar but smaller effects. The thermally modified oil was not better than ordinary SBO necessitating the need for an optimised blending strategy. Lubricant blends were prepared by mixing thermally modified SBO with a series of compatible ester-based synthetic fluids. These displayed oxidative stabilities, by pressurised differential scanning calorimetry, similar to the bio-based oil. Furthermore, the kinematic viscosity and pour point of the lubricant blend could be accurately controlled by careful tuning of the blend ratio.

The Internet may be an effective method for delivering programs that help them adopt healthy behaviors. Objective: To collect information to design content and structure for a teen-friendly website promoting healthy eating and physical activity behaviors. Methods: Qualitative research, encompassing both focus group and interview techniques, were used to design the website. Participants were 12-17 year olds in Houston, Texas, and West Lafayette, Indiana. Results: A total of 133 participants took part in 26 focus groups while 15 participated in one-on-one interviews to provide guidance for the development of teen-friendly content and structure for an online behavior change program promoting healthy eating and physical activity to 12-17 year olds. The youth made suggestions to overcome common barriers to healthy eating and physical activity. Their feedback was used to develop "Teen Choice: Food & Fitness," a 12-week online behavior change program, populated by 4 cartoon character role models. Conclusions: It is critical that members of the target audience be included in formative research to develop behavior change programs that are relevant, appealing, and address their needs and interests.

Under center-pivot sprinkler irrigation, kinetic energy transferred to the soil prior to crop canopy development can have a substantial effect on seasonal runoff and soil erosion, especially when the soil is not protected by crop residue cover. Droplet kinetic energy of seven commercial off-center action rotating spray-plate sprinklers was characterized over a range of flow rates and pressures. Sprinkler droplet kinetic energy was characterized using two methods: droplet kinetic energy per unit sprinkler discharge, and droplet kinetic energy applied per unit water depth under center-pivot irrigation with 3 m sprinkler spacing. The two methods are correlated, but kinetic energy per unit sprinkler discharge does not represent droplet kinetic energy applied to the soil under center-pivot irrigation, as the correlation coefficient is not equal to 1. Droplet kinetic energy applied for a given flow rate and operating pressure varied by up to 200% among the sprinklers evaluated. Designing sprinklers that minimize the kinetic energy transferred to bare soil will require a monotonic decreasing application rate with radial distance, as any peak in application rate at large radial distances will result in a peak in specific power. Kinetic energy per unit drop volume will always increase with radial distance, as drops sizes get larger with radial distance. The sprinkler with the lowest droplet kinetic energy applied or the lowest average composite specific power may not necessarily be the sprinkler that results in the greatest infiltrated depth or the least potential runoff. Thus, droplet kinetic energy is not suitable as a single parameter to select between sprinkler choices.

These issues will force major changes to physical and managerial aspects as well as the design of water delivery and on-farm irrigation systems. Thus, a water- and energy-limited future will be the likely catalyst that finally brings many of the existing precision agricultural technologies together for irrigated agriculture. Resource conservation as well as achieving environmental benefits will probably require the adoption of non-uniform water applications, also known as site-specific irrigation, for many growers. The goal of site-specific irrigation is to conserve water by directing the amount and frequency of water applications according to established spatial and temporal crop water requirements. However, more than 20 years of private and public research on site-specific irrigation has resulted in very limited commercial adoption of the technology. The current state of the art of site-specific center-pivot and linear-move sprinkler irrigation is reviewed. Several general barriers to adoption of the technol-ogy and various knowledge gaps are identified. The primary reason for the very low rate of commercial adoption appears to be the absence of a market for the technology and a low rate of return. Documented and proven water conservation strategies using site-specific sprinkler irrigation for crop production are quite limited, and its cost-effectiveness has not been demonstrated. Simulation studies comparing conventional and site-specific irrigation have reported water savings of 0% to 26% for well-watered crop production, and the greatest savings are most likely to occur in humid climates by spatially maximizing utilization of non-uniform growing season precipitation. In arid and semi-arid climates, the greatest potential water savings could come from highly managed deficit irrigation strategies in which spatial management of soil water deficit timing is used to maximize net return rather than yield. Future research needs to focus on developing and documenting cost-effective site-specific water conservation strategies to support market development for these advanced and needed irrigation technologies.

This study was conducted to: (1) evaluate the effects of a narrow wheat strip, varying manure application rates, and different overland flow rates on runoff nutrient loads following application of beef cattle manure; (2) determine the upper capacity of a narrow wheat strip to reduce nutrient loads by applying excessive amounts of manure; and (3) compare the effectiveness of narrow wheat strips and grass hedges in reducing runoff nutrient loads. A 1.4 m wide strip of actively growing winter wheat was located at the bottom of selected 0.75 m wide by 4.0 m long plots. Three 30 min simulated rainfall events, separated by 24 h intervals, were applied at an intensity of 70 mm h(-1) to the plots. The wheat strips were effective in reducing runoff loads of NO(3-)N, NH(4-)N, and total nitrogen (TN). Runoff loads of dissolved reactive phosphorus (DP), particulate phosphorus (PP), total phosphorus (TP), NH4-N, and TN were significantly influenced by manure application rate. The application of ma-nure to meet a 2-year rather than a 1-year corn Prequirement did not significantly increase DP, PP, or TP loads. Howev-er, application of manure to meet a 4-year P requirement resulted in DP, PP, and TP loads that were significantly greater than those obtained for a 2-year P requirement. Runoff rate significantly affected each of the measured water quality parameters. The actively growing wheat strips were much less effective than grass hedges in reducing runoff nutrient loads.

Although NE and GD share a common pathogen, Clostridium perfringens, they differ in other important aspects such as clinical signs, pathologic symptoms, and age of onset. The primary virulence factors of C. perfringens are its four major toxins ( alpha alpha , beta beta , epsilon epsilon , iota iota ) and the newly described NE B-like (NetB) toxin. While neutralizing antibodies against some C. perfringens toxins are associated with protection against infection in mammals, the serologic responses of NE- and GD-afflicted birds to these toxins have not been evaluated. Therefore, we measured serum antibody levels to C. perfringens alpha alpha -toxin and NetB toxin in commercial birds from field outbreaks of NE and GD using recombinant toxin-based enzyme-linked immunosorbent assay (ELISA). Initially, we used this ELISA system to detect antibody titers against C. perfringens alpha alpha -toxin and NetB toxin that were increased in birds experimentally co-infected with Eimeria maxima and C. perfringens compared with uninfected controls. Next, we applied this ELISA to field serum samples from flock-mated birds with or without clinical signs of NE or GD. The results showed that the levels of antibodies against both toxins were significantly higher in apparently healthy chickens compared to birds with clinical signs of NE or GD, suggesting that these antitoxin antibodies may play a role in protection against NE and GD.

Since this field is wide, this overview is limited and highlighting only those water purification and treatment processes, which have been realized in industrial scale up or pilot applications. The zeolite ion exchange pilot installation with a hydraulic loading rate of 900 L/h was situated at the field experimental facility of Water Research Institute in Vajnory, the closed vicinity of Bratislava, during the autumn of 1986. Surface water purification by means of chemical coagulation and flocculation supported by the powdered natural zeolite was carried out in 1984 to save the drinking water reservoir (upper part of Ondava river) settled by about 10,000 equivalent inhabitants. Ammonia removal from tannery wastewater using the clinoptilolite-rich tuff with chemical regeneration and regenerant recovery by air stripping was carried out for several months in 1987 at the mixed Wastewater Reclamation Facility in Zlin (Moravia region). Zeocem company is currently producing manganese-dopped grain-sized clinoptilolite-rich tuff under the trade mark Clinopur, purchased for water purification and for the removal of Mn with Fe pollutants removal.

Cold plasma is a novel antimicrobial intervention that can eliminate foodborne pathogens. The objective of this work was to evaluate the efficacy of rapid cold plasma treatments in eliminating Salmonella and Escherichia coli O157:H7 from dry almonds. Three isolates of Salmonella (S. Anatum F4317, S. Stanley H0558, and S. Enteritidis PT30) and 3 isolates of E. coli O157:H7 (C9490, ATCC 35150, and ATCC 43894) were separately grown and spot-inoculated (10 mu L) onto whole almonds and allowed to dry for 10 min. Inoculated almonds were treated with a cold plasma jet, with treatment variables evaluated in a factorial design for each isolate: time, distance, and feed gas. Treatment time was 0 s (control), 10 s, or 20 s. Distance from the emitter was 2, 4, or 6 cm. Feed gas was dry air or nitrogen. After treatment, the almonds were sampled using swabs. Survivors were enumerated on tryptic soy agar (TSA) plates. Cold plasma significantly reduced both pathogens on almonds. The greatest reduction observed was 1.34 log cfu/mL reduction of E. coli O157:H7 C9490 after 20 s treatment at 6 cm spacing. The interaction of treatment time with distance from plasma emitter head was complex, and isolate-dependent. Longer duration of treatment did not always result in enhanced reductions. In general, nitrogen as a feed gas resulted in a reduced antimicrobial efficacy compared to dry air. These results indicate that short pulses of atmospheric pressure cold plasma can significantly reduce Salmonella and E. coli O157:H7 on almonds. Practical Application: Contamination of raw nuts, including almonds, is a food safety concern. Cold plasma is a novel antimicrobial intervention that can eliminate foodborne pathogens. The results of this research show that short pulses of atmospheric pressure cold plasma can significantly reduce Salmonella and E. coli O157:H7 on almonds. A 20 s treatment was sufficient to achieve up to 1.34 log reduction, depending on treatment parameters. This process is a waterless, contact-less, chemical-free method of killing hard-to-reach pathogens on almonds.

Individual plants were sampled with sticky-traps on 8 dates from May 1997 to August 1998. We sampled 5,040 adult thrips from 26 species in 19 genera, of which 16 could be identified to species. Four families were represented, Thripidae (17 species comprised 98.2 % of the collected specimens), Phlaeothripidae (5 species comprised 1.6%), Aeolothripidae (2 species comprised 0.1%) and Heterothripidae (1 species comprised 0.1%). A total of 16 species (84.2%) were phytophagous on flowers and leaves, 2 (10.5%) were predators, one (5.2%) was mycophagous. Feeding habits for 7 species are unknown. Thrips abundance was positively correlated with plant volume, but not with insect richness. Strikingly for a natural area, Frankliniella occidentalis accounted for 73.6% of the total collection of the sampled thrips, which together with Chirothrips falsus, Microcephalothrips abdominalis, Frankliniella gossypiana, and Neohydatothrips signifier, comprised 94.0% of the total number of collected thrips. Main abundances, considering all thrips species, occurred in fall and spring; no thrips were collected during winter. This seasonal pattern of occurrence was observed for the most abundant thrips species. In summary, the results of this study were: 1) few thrips species were found to be specialists; only 2 thrips species out of 12 studied, showed strong preference for host plants, 2) presence of a high percentage of positive associations, and a low percentage of negative associations, 3) the role of plant volume explained more than 80% of variance of thrips abundance. These results suggest that the studied thrips community has low plant specificity and the pattern of plant use observed could be the consequence of generalist feeding diets.

It is a fundamental ecosystem parameter that is a required input of process-based plant growth and biogeochemical models. Direct measurement of LAI is the most accurate method, but is destructive, time-consuming, and labor-intensive. LAI is highly variable in time and space on sagebrush-steppe rangelands, and a rapid, nondestructive method is desirable to understand ecosystem processes. The point-intercept method is nondestructive and has been demonstrated to provide accurate LAI estimates, but the method is time-consuming. LAI measurement with the Accupar ceptometer (Decagon Devices, Pullman, WA) is nondestructive and faster than the point-intercept method, but has not been evaluated on sagebrush-steppe rangelands. The objective of this study was to evaluate the ceptometer for measurement of LAI in sagebrush-steppe rangelands. Ceptometer and point-intercept LAI data were collected at six sites in sagebrush-steppe rangelands and the values were compared. We found that 1) ceptometer LAI data were consistently greater than point-intercept LAI data, 2) ceptometer data were much more variable than the point-intercept data based on standard deviations, and 3) the overall correlation between the two methods was very weak (r2 == 0.15). The much greater ceptometer LAI values were, at least partly, due to the large woody component of the vegetative cover. We attribute the high variability of ceptometer-measured LAI to high instrument sensitivity of the angle of the instrument relative to the sun.

In this paper, we describe a semiautomated approach for estimating canopy-gap size distributions in rangelands from high-resolution (HR) digital images using image interpretation by observers and statistical image classification techniques. We considered two different classification methods (maximum-likelihood classification and logistic regression) and both pixel-based and object-based approaches to estimate canopy-gap size distributions from 2- to 3-cm resolution UltraCamX color infrared aerial photographs for arid and semiarid shrub sites in Idaho, Nevada, and New Mexico. We compare our image-based estimates to field-based measurements for the study sites. Generally, percent of input points correctly classified and kappa coefficients of agreement for plot image classifications was very high. Plots with low kappa values yielded canopy gap estimates that were very different from field-based estimates. We found a strong relationship (R2 > 0.9 for all four methods evaluated) between image- and field-based estimates of the total percent of the plot in canopy gaps greater than 50 cm for plots with a classification kappa of greater than 0.5. Performance of the remote sensing techniques varied for small canopy gaps (25 to 50 cm) but were very similar for moderate (50 to 200 cm) and large (> 200 cm) canopy gaps. Our results demonstrate that canopy-gap size distributions can be reliably estimated from HR imagery in a variety of plant community types. Additionally, we suggest that classification goodness-of-fit measures are a potentially useful tool for identifying and screening out plots where precision of estimates from imagery may be low. We conclude that classification of HR imagery based on observer-interpreted training points and image classification is a viable technique for estimating canopy gap size distributions. Our results are consistent with other research that has looked at the ability to derive monitoring indicators from HR imagery.

We evaluated the effectiveness of wetting agents and simulated anchor chaining for improving seedling growth and survival in water-repellent soil, for the native perennial bluebunch wheatgrass (Pseudoroegneria spicata) and invasive annual cheatgrass (Bromus tectorum). Research was performed in a glasshouse, on 20-cm-diameter soil cores that were excavated from underneath burned Utah juniper (Juniperus osteosperma) trees. The experiment was arranged as a randomized split-plot design, with the two grass species sown separately under four soil treatments: 1) no treatment (control), 2) simulated anchor chaining (hereafter referred to as "till"), 3) wetting agent, and 4) till plus wetting agent. Soil water content was highest in the wetting agent treatment, lower for till, and lowest in the control. Overall, the response of bluebunch wheatgrass and cheatgrass was similar among treatments. At the conclusion of the study, wetting agent cores had twice as many seedlings as the control, while the till and control were similar. Despite a lower number of seedlings, tilling in general resulted in the same level of biomass as the wetting agent treatment. Overall, biomass in the till and wetting agent treatments was at least twofold higher than the control. No benefit was found in applying both till and wetting agent treatments together in comparison to just applying wetting agent. Because of a lack of correlation between glasshouse and field settings the results of this study need to be interpreted with caution. Our data may indicate that if cheatgrass is not already present on the site, anchor chaining or treating the soil with wetting agent can increase establishment of seeded species.

K. Koch. Use of insecticides is among the most important of the limited control options available against this pest. Glass-vial bioassays were used to evaluate the toxicity of selected synthetic pyrethroid and organophosphate insecticides to adult brown stink bug captured in blacklight traps. A comparison was also made of toxicity of lambda -cyhalothrin to brown stink bug collected directly from the field to those captured in blacklight traps. Lethal concentration value (LC50) (upper and lower 95% confidence limits) for dicrotophos for 24-hour response, 0.30 (0.24-0.37) mu g per vial, was significantly less compared to acephate with an LC50 of 1.38 (1.01-1.81) mu g per vial and chlorpyrifos with an LC50 of 5.00 (4.27-5.67) mu g per vial. Dicrotophos was five- and 17-fold more toxic to brown stink bug than acephate and chlorpyrifos, respectively. The order of toxicity to brown stink bug for synthetic pyrethroids was: bifenthrin = zeta-cypermethrin = gamma -cyhalothrin > lambda -cyhalothrin > cypermethrin. LC50 values ranged from 0.27 (0.18-0.51) for bifenthrin to 1.35 (1.01-1.90) mu g per vial for cypermethrin, a five-fold difference. LC50 values for brown stink bugs collected from the field or captured in blacklight traps were not significantly different which suggests that brown stink bugs captured in blacklight traps may be used for insecticide bioassays. Data presented are useful for selecting insecticides for control and establishing baselines to monitor development of resistance of brown stink bugs to insecticides in the Brazos Valley of Central Texas.

The alfalfa leafcutting bee, Megachile rotundata (F.) Hymenoptera: Megachilidae, and the honey bee, Apis mellifera L. Hymenoptera: Apidae, are the most commonly used pollinators. The fungus Beauveria bassiana (Balsamo) Vuillemin has been proposed as a microbial control for Lygus spp. (Hemiptera: Miridae), a common pest of this crop. In laboratory bioassays, we found that adult alfalfa leafcutting and honey bees were susceptible to three strains of B. bassiana. A commercial strain, GHA, was the most pathogenic and virulent, causing approximately 45-80% mortality at a dose of 1 105 conidia per bee, and >80% mortality at 1 106 conidia per bee. A new strain that is very pathogenic to lygus, 17-41, caused less than 20% mortality in honey bees at 1 105 conidia per bee. The alfalfa leafcutting bee was more susceptible than honey bees to all three strains of the fungus. B. bassiana killed almost twice as many alfalfa leafcutting bees, and mortality occurred 1-3 days earlier. Field experiments are needed to further determine the risks this microbial control agent poses to pollinators.

In the longer term, tree species may be unable to persist in some locations while they become established in new places. Over both time frames, forest tree biodiversity may change in unexpected ways. Using repeated inventory measurements five years apart from more than 7000 forested plots in the eastern United States, we tested three hypotheses: phylogenetic diversity is substantially different from species richness as a measure of biodiversity; forest communities have undergone recent changes in phylogenetic diversity that differ by size class, region, and seed dispersal strategy; and these patterns are consistent with expected early effects of climate change. Specifically, the magnitude of diversity change across broad regions should be greater among seedlings than in trees, should be associated with latitude and elevation, and should be greater among species with high dispersal capacity. Our analyses demonstrated that phylogenetic diversity and species richness are decoupled at small and medium scales and are imperfectly associated at large scales. This suggests that it is appropriate to apply indicators of biodiversity change based on phylogenetic diversity, which account for evolutionary relationships among species and may better represent community functional diversity. Our results also detected broadscale patterns of forest biodiversity change that are consistent with expected early effects of climate change. First, the statistically significant increase over time in seedling diversity in the South suggests that conditions there have become more favorable for the reproduction and dispersal of a wider variety of species, whereas the significant decrease in northern seedling diversity indicates that northern conditions have become less favorable. Second, we found weak correlations between seedling diversity change and latitude in both zones, with stronger relationships apparent in some ecoregions. Finally, we detected broadscale seedling diversity increases among species with longer-distance dispersal capacity, even in the northern zone, where overall seedling diversity declined. The statistical power and geographic extent of such analyses will increase as data become available over larger areas and as plot measurements are repeated at regular intervals over a longer period of time.

(giant reed) to leaf damage and partial defoliation AN - 1008841608; 16532690 AB - Arundo donax (giant reed) is a tall clonal invasive grass which has impacted many riparian ecosystems in the US. Experiments tested the hypotheses (1) that defoliation would affect A. donax stem growth and leaf production and (2) that leaf damage or removal would influence A. donax photosynthetic rates using a combination of field and laboratory settings. Leaf defoliation did not affect the height of stems or the number of leaves per stem for plants growing at a field site. Leaf damage did not influence the electron transport rate (ETR) for damaged or adjacent leaves, and defoliated stems maintained ETR which were similar to those of undamaged leaves. These findings suggest that moderate to low levels of leaf damage and/or defoliation alone may not significantly influence growth of A. donax stems and leaves and, therefore, may not reduce A. donax persistence in a particular habitat. Further, these results provide a benchmark against which to judge the effects of management approaches which affect A. donax shoots.

Our objectives were to (a) evaluate the yield (Y) potential of sunflower under full and deficit irrigation (IR), (b) determine if water productivity (WP) and irrigation water productivity (IWP) of sunflower were affected by soil textural class differences and (c) compare the WP relationship to a benchmark maximum productivity relationship for consideration of limitations to crop yield in a semiarid environment. Sunflower was grown in 2008 and 2009 in 48 weighing lysimeters under an automated rain shelter containing soil monoliths of four regional soils - clay loam, silt loam, sandy loam or fine sand (12 each) - at Bushland, TX, USA, a semiarid region of the southern Great Plains. Irrigation treatments were 25%, 50%, 75% and 100% replacement of evapotranspiration. The regression of IR:Y for all soil textural classes showed that irrigation increased yield by 0.47 g m super(-2 mm) super(-)1 in 2008 and 0.51 g m super(-2 mm) super(-)1 in 2009. Averaged across irrigation treatments, the WP of the crops in the fine sand (0.54 kg m super(-3) was larger than that of the crops in the silt loam (0.46 kg m) super(-)3) and clay loam (0.44 kg m super(-3). The IWP of the crops in the fine sand (1.0 kg m) super(-)3) and the sandy loam (0.96 kg m super(-3) were significantly larger than the IWP of the crops in the clay loam (0.72 kg m) super(-)3). Yields were as much as 30% lower at full irrigation levels compared with benchmark maximum yields. Probable limitations to increased yield include high evaporative deficits and soil water evaporation. Although sunflower may be a drought-adapted crop, maximum yields may be difficult to achieve due to the climatic conditions in the southern Great Plains.

AN - 923190226; 22280497 AB - Long-term effectiveness of biochar for heavy metal stabilization depends upon biochar's sorptive property and recalcitrance in soil. To understand the role of carboxyl functional groups on heavy metal stabilization, cottonseed hull biochar and flax shive steam-activated biochar having a low O/C ratio (0.04-0.06) and high fixed carbon content (~80% dry weight basis) were oxidized using concentrated H(2)SO(4)/HNO(3) and 30% HNO(3). Oxidized and unoxidized biochars were characterized for O/C ratio, total acidity, pH, moisture, ash, volatile matter, and fixed carbon contents, Brunauer-Emmett-Teller surface area, and attenuated total reflectance Fourier transform infrared spectral features. Characterized biochars were amended (2%, 5%, 10%, and 20% in grams of biochar per gram of soil) on a sandy, slightly acidic (pH 6.27) heavy metal contaminated small arms range soil fraction (<250 μm) having low total organic carbon (0.518%) and low cation exchange capacity (0.95 cmol(c) kg(-1)). Oxidized biochars rich in carboxyl functional groups exhibited significantly greater Pb, Cu, and Zn stabilization ability compared to unoxidized biochars, especially in pH 4.9 acetate buffer (standard solution for the toxicity characteristic leaching procedure). Oppositely, only oxidized biochars caused desorption of Sb, indicating a counteracting impact of carboxyl functional groups on the solubility of anions and cations. The results suggested that appropriate selection of biochar oxidant will produce recalcitrant biochars rich in carboxyl functional groups for a long-term heavy metal stabilization strategy in contaminated soils.

Carbon sequestration has become a recognized forest management objective, but the full carbon storage potential of forests is not well understood. The premise of this study is that old-growth forests can be expected to provide a reasonable estimate of the upper limits of carbon storage for similar forest types in comparable site conditions. We sampled old-growth stands in Maine, Vermont, and New Hampshire to establish benchmark values for carbon storage in the forests of northern New England. Our specific objectives were: (1) develop estimates of carbon stocks in key live and dead biomass carbon pools of hardwood and softwood forests in northern New England, (2) compare these values to other estimates of carbon stocks in old-growth forests, and (3) compare data collected from mature second-growth forests to the old-growth benchmark values. Twelve sites in Vermont, New Hampshire, and Maine were sampled to estimate total carbon stocks in aboveground live and dead biomass, down dead wood, forest floor, and soil to 20cm. Total carbon stocks averaged 216t/ha for northern hardwoods and 267t/ha in softwood sites, with 116 and 125t/ha in the aboveground live tree biomass for hardwoods and softwoods, respectively. Our results showed old-growth softwood averaged about 25% more carbon than old-growth hardwood, primarily due to the higher carbon amounts in the thick forest floors characteristic of old-growth softwood. Old-growth hardwoods supported live biomass carbon stocks similar to those in mature hardwood stands (about 80-120years old), although forest floor stocks in old-growth were about twice as high (a non-significant difference).

(Acari: Prostigmata: Eriophyidae) collected from Dipsacus laciniatus L. (Dipsacaceae) in northern Serbia, is described and illustrated, including digital micrographs depicting key morphological characters. Differential diagnosis is provided in comparison with Aculops salixis Xue, Song et Hong, Aculops rhodensis (Keifer), Aculops hussongi Keifer and Aculops oblongus (Nalepa). This is the first eriophyoid mite species in the genus Aculops described from a host plant in the family Dipsacaceae and it is only the second eriophyoid known from a host species in the genus Dipsacus L. This mite was found during surveys for natural enemies of Dipsacus spp., as part of a classical biological control program.

AN - 915038842; 22226197 AB - Furfural and 5-hydroxymethylfurfural (HMF) are inhibitors generated by lignocellulosic biomass pretreatment such as dilute acid hydrolysis that inhibit microbial growth and interfere with subsequent fermentation. It is possible to in situ detoxify these inhibitory compounds by aldehyde reductions using tolerant Saccharomyces cerevisiae. YOL151W (GRE2) is a commonly recognized up-regulated gene expressed under stress conditions that encodes reductase activities toward furfural and HMF using cofactor NADH. Applying a directed enzyme evolution approach, we altered the genetic code of GRE2 yielding two mutants with amino acid substitutions of Gln261 to Arg261 and Phe283 to Leu283; and Ile107 to Val107, Gln261 to Arg261, and Val285 to Asp285 for strain Y62-C11 and Y62-G6, respectively. Clones of these mutants showed faster growth rates and were able to establish viable cultures under 30 mM HMF challenges when compared with a wild type GRE2 clone when inoculated into synthetic medium containing this inhibitor. Compared with the wild type control, crude cell extracts of the two mutants showed 3- to 4-fold and 3- to 9-fold increased specific enzyme activity using NADH toward HMF and furfural reduction, respectively. While retaining its aldehyde reductase activities using the cofactor NADH, mutant Y62-G6 displayed significantly greater reductase activities using NADPH as the cofactor with 13- and 15-fold increase toward furfural and HMF, respectively, as measured by its partially purified protein. Using reverse engineering and site directed mutagenesis methods, we were able to confirm that the amino acid substitution of the Asp285 is responsible for the increased aldehyde reductase activities by utilizing the additional cofactor NADPH.

16507509 AB - Airborne transmission of bacterial pathogens from point sources (e.g., ranches, dairy waste treatment facilities) to areas of food production (farms) has been suspected. Determining the incidence, transport and viability of extremely low levels of pathogens require collection of high volumes of air and characterization of live bacteria from aerosols. We monitored the numbers of culturable bacteria in urban aerosols on 21 separate days during a 9 month period using high volume cyclonic samplers at an elevation of 6 m above ground level. Culturable bacteria in aerosols fluctuated from 3 CFU to 6 million CFU/L of air per hour and correlated significantly with changes in seasonal temperatures, but not with humidity or wind speed. Concentrations of viable bacteria determined by fluorescence staining and flow cytometry correlated significantly with culturable bacteria. Members of the phylum Proteobacteria constituted 98% of the bacterial community, which was characterized using 16S rRNA gene sequencing using DNA from aerosols. Aqnabacterium sp., previously characterized from aquatic environments, represented 63% of all clones and the second most common were Burkholderia sp; these are ubiquitous in nature and some are potential human pathogens. Whole genome amplification prior to sequencing resulted in a substantial decrease in species diversity compared to characterizing culturable bacteria sorted by flow cytometry based on scatter signals. Although 27 isolated colonies were characterized, we were able to culture 38% of bacteria characterized by sequencing. The whole genome amplification method amplified DNA preferentially from Phyllobacterium myrsinacearum, a minor member of the bacterial communities, whereas Variovorax paradoxus dominated the cultured organisms.

Of the numerous Campylobacter assays that do exist, to our knowledge none has been empirically tested for specificity using high-throughput sequencing. Here we demonstrate the power of next-generation sequencing to determine the specificity of a widely cited Campylobacter-specific polymerase chain reaction (PCR) assay and describe a rapid method for direct cell suspension PCR to quickly and easily screen samples for Campylobacter. We present a specific protocol which eliminates the need for time-consuming and expensive genomic DNA extractions and, using a high-processivity polymerase, demonstrate conclusive screening of samples in 99%) sensitive, and spike-back experiments demonstrated a detection threshold of <102 CFU mL-1. Additionally, we present 2 newly designed broad-range bacterial primer sets targeting the 23S rRNA gene that have wide applicability as internal amplification controls. Empirical testing of putative taxon-specific assays using high-throughput sequencing is an important validation step that is now financially feasible for research, regulatory, or clinical applications.

Here, we examine ecological and management implications of nitrogen (N) dynamics during early forest stand development in productive commercial tree species with narrow (Populus deltoides Bartr. and Platanus occidentalis L.) and broad (Liquidambar styraciflua L. and Pinus taeda L.) site requirements while grown with a range of nutrient and water resources. Methods: We constructed N budgets by measuring N concentration ([N]) and N content (N sub(C)) of above- and belowground perennial and ephemeral tissues, determined N uptake (N sub(UP)), and calculated N use efficiency (NUE). Results: Forest stands regulated [N] within species-specific operating ranges without clear temporal or treatment patterns, thus demonstrating equilibrium between tissue [N] and biomass accumulation. Forest stand N sub(C) and N sub(UP) increased with stand development and paralleled treatment patterns of biomass accumulation, suggesting productivity is tightly linked to N sub(UP). Inclusion of above- and belowground ephemeral tissue turnover in N sub(UP) calculations demonstrated that maximum N demand for narrow-sites adapted species exceeded 200 kg N ha super(-1) year super(-1) while demand for broad-site adapted species was below this level. NUE was species dependent but not consistently influenced by N availability, suggesting relationships between NUE and resource availability were species dependent. Conclusions: Based on early stand development, species with broad site adaptability are favored for woody cropping systems because they maintain high above- and belowground productivity with minimal fertilization requirements due to higher NUE than narrow site adapted species.

Such structures are predicted to be spatially isolated resource patches with frequent population bottlenecks that should influence their genetic structure. Genetic diversity and differentiation among nine populations of T. castaneum collected from wheat and rice mills (ranging from <1-5,700 km apart) were investigated using eight polymorphic loci (microsatellites and other insertion-deletion polymorphisms, each with 3-14 alleles). Seventy-two locus-by-population combinations were evaluated, of which 31 deviated significantly from Hardy-Weinberg equilibrium, all because of a deficiency of heterozygotes. AMOVA analysis indicated significant differences among populations, with 8.3% of the variation in allele frequency resulting from comparisons among populations, and commodity type and geographic region not significant factors. Although there were significant differences in genetic differentiation among populations (FST values = 0.018-0.149), genetic distance was not significantly correlated with geographic distance. Correct assignment to the source population was successful for only 56% of individuals collected. Further analyses confirmed the occurrence of recent genetic bottlenecks in five out of nine populations. These results provide evidence that populations of T. castaneum collected from mills show spatial genetic structure, but the poor ability to assign individuals to source populations and lack of isolation by distance suggest greater levels of gene flow than predicted originally.

Cannibalistic aggressive interactions further increase the risk of wounding and pathogen transmission in crowds. Nymphal Mormon crickets Anabrus simplex Haldeman were collected in Montana and reared in the laboratory either solitarily or at densities similar to that experienced by Mormon crickets in migratory bands. As teneral adults, solitarily-reared Mormon crickets tended to have greater phenoloxidase activity than those reared in groups. Sampling enzyme activity a second time when the adults were nearing reproductive maturity, group-reared Mormon crickets had elevated levels of prophenoloxidase and encapsulated foreign objects faster than solitarily-reared insects. Rearing density did not have a significant effect on either the darkness of the cuticle or antibacterial activity. This is the first report of age-related responses of adult insect immunity to crowding.

However, observational evidence suggests that concentrated flow is prevalent from agricultural fields. Over time sediment can accumulate in riparian buffers forming berms that restrict sheet flow; these berms ultimately back up surface runoff, resulting in an eventual breakthrough that concentrates overland flow. This study examines the occurrence of concentrated flow paths (CFPs) in riparian buffers at both the field and watershed scale. At the field scale, intensive topographic surveys were conducted at ten field sites in southern Illinois. To assess the prevalence of CFPs at the watershed scale, three watersheds in southern Illinois were selected for walking stream surveys along randomly selected 1,000 m reaches. CFPs were identified in all topographic surveys and all walking stream surveys. Among field sites, concentrated flow accounted for 82.5-100% of the drainage leaving the agricultural fields. Sediment berm accumulation was identified at all field sites and was positively correlated with CFP size. At the watershed scale, CFPs were more abundant in agricultural areas compared to forested land. Results from this study indicate that concentrated flow was prevalent across all study sites at both the field and watershed scale. Thus, surface water quality may suffer in areas with poorly functioning buffers, and managers must consider the occurrence of CFPs when designing and maintaining riparian buffers to protect stream water quality.

Swainsonine concentrations in Oxytropis sericea were influenced by location, plant part, and the developmental stage of the plant. Concentrations followed similar trends at each location, generally increasing over the growing season in above-ground parts until the plant reaches maturity with no change in concentration in the crowns. At the onset of senescence, swainsonine decreased in floral parts to less than half of the peak concentration. Similar to swainsonine concentrations, endophyte amounts were influenced by location, plant part, and the developmental stage of the plant. Likewise, endophyte amounts generally increased over the growing season in above ground parts and remained static in the crowns at all four locations. Swainsonine in Oxytropis sericea was positively associated with the endophyte Undifilum, which is responsible for swainsonine biosynthesis.

Methods: Lines of a recombinant inbred population, derived from Miyakojima and Gifu, were tested for whole-root ferric reductase activity and shoot chlorosis following iron-limited growth. A ferric reductase gene (LjFRO1) was cloned from both parents. Protein sequence analysis, transcript abundance, and yeast complementation studies were conducted with the two parental alleles. Results: A single quantitative trait locus (QTL) was identified for both ferric reductase activity and shoot chlorosis, with each QTL explaining ~30% of the variation and both overlapping across the same region of chromosome 3. LjFRO1 mapped to chromosome 3, but to a region adjacent to the reductase and chlorosis loci. Nucleotide variation in LjFRO1 parental alleles was identified, as were minor functional differences between the two proteins. Conclusions: The results indicate that both allelic variation (providing potential functional differences) and unidentified molecular components (derived from non-LjFRO1 genetic loci) can contribute to the regulation of ferric reductase activity and chlorosis susceptibility.

Methods: Pyrolysis gas-chromatography mass-spectrometry (py-GC/MS) analyzes biochemical fragments which can be related to lignin, polysaccharide, lipid, nitrogen (N)-bearing, non-lignin aromatics, and phenol source compounds. Thermochemolysis using tetramethylammonium hydroxide (TMAH) combined with py-GC/MS improves detection of lignin, cutin, and suberin-derived compounds. To examine the advantages and disadvantages of both methods for characterizing plant and soil biochemistry, we characterized non-polypod and polypod fern and angiosperm live tissues, roots and soils from the Kohala Mountains, Hawaii. Results: Py-GC/MS provided a broad biochemical overview of compound groups including lignin, polysaccharide, lipid, N-bearing, non-lignin aromatics and phenol groups while TMAH-py-GC/MS detailed lignin units and fatty acids at the expense of the other categories. TMAH-py-GC/MS provided more detailed data on lignin, cutin, suberin and tannin-derived compounds. Both methods detected differences in lignin units between species, although p-coumaric and ferulic acids, predominantly found in ferns, were only observed with TMAH-py-GC/MS. Conclusions: Both py-GC/MS and TMAH-py-GC/MS are methods to detect compound-specific plant biomarkers, but are most useful when combined for their complimentary results.

The developmental time for each life stage and the total time from egg to adult decreased with increasing temperature. Eggs required the longest time to develop followed by fifth instars and then first-instars. Total developmental time from egg to adult was shortest at 32 degree C, requiring 18.0 +/- 0.3 d and 416.7 +/- 31.3 DD above 7.9 degree C, the estimated minimum temperature for development from egg to adult. Sex did not affect total developmental times and did not affect median survival time. Adults lived significantly fewer days at high temperatures (30-32 degree C: 17-19 d) compared with temperatures below 30 degree C (range: 24.5-39.4 d) and the number of eggs laid per day increased from approximately 4 at 18 degree C to a maximum of 9.5 eggs per day at 30 degree C Total egg production over the lifetime of female tarnished plant bugs increased with temperature reaching a maximum of 175 eggs on average at 27 degree C, total egg production declined at temperatures above 27 degree C (30 degree C: 110.8, 32 degree C: 77.3 eggs per female). The highest net reproductive rate 74.5 (R0) was obtained from insects maintained at 27 degree C. The intrinsic rate of natural increase (rm) increased linearly with temperature to a maximum value of 0.1852 at 30 degree C, and then decreased at 32 degree C Generation and doubling times of the population were shortest at 30 degree C, 21.0 and 3.7 d, respectively.

Although a minor problem in its native Africa, it is an invasive pest of honey bees in the United States and Australia. Adult beetles enter bee hives to oviposit and feed. Larval development occurs within the hive, but mature larvae leave the hive to pupate in soil. The numbers leaving, which can be estimated by trapping, measure the reproductive success of adult beetles in the hive over any given period of time. We describe a trap designed to intercept mature larvae as they reach the end of the bottom board on their way to the ground. Trap efficiency was estimated by releasing groups of 100 larvae into empty brood boxes and counting the numbers trapped. Some larvae escaped, but mean efficiency ranged from 87.2 to 94.2%. We envision the trap as a research tool for study of beetle population dynamics, and we used it to track numbers of larvae leaving active hives for pupation in the soil. The traps detected large increases and then decreases in numbers of larvae leaving colonies that weakened and died. They also detected small numbers of larvae leaving strong European and African colonies, even when no larvae were observed in the hives.

The effect of hydrogenase inhibitors (H sub(2), carbon monoxide (CO), and methyl viologen) on product selectivity was investigated. The anticipated effect of these hydrogenase inhibitors was to decrease acetate production. However, shifts to ethanol and lactate production are also observed as a function of cultivation conditions. When the sparge gas of cellobiose-limited chemostat cultures was switched from N sub(2) to H sub(2), acetate declined, and ethanol production increased 350%. In resting cell suspensions, lactate increased when H sub(2) or CO was the inhibitor or when the cells were held at elevated hyperbaric pressure (6.8 atm). In contrast, methyl-viologen-treated resting cells produced twice as much ethanol as the other treatments. The relationship of chemostat physiology to methyl viologen inhibition was revealed by glucose transport experiments, in which methyl viologen decreased the rate of glucose transport by 90%. C. thermocellum produces NAD super(+) from NADH by H sub(2), lactate, and ethanol production. When the hydrogenases were inhibited, the latter two products increased. However, excess substrate availability causes fructose 1,6-diphosphate, the glycolytic intermediate that triggers lactate production, to increase. Compensatory ethanol production was observed when the chemostat fluid dilution rate or methyl viologen decreased substrate transport. This research highlights the complex effects of high concentrations of dissolved gases in fermentation, which are increasingly envisioned in microbial applications of H sub(2) production for the conversion of synthetic gases to chemicals.

Because of the close link to forest productivity in the region, understanding processes that have affected the present-day distribution and characteristics of these ash mantles is important for forest soil management. Presence or absence, thickness, and degree of ash mantle mixing were evaluated at 84 randomly selected stratified sites in the Palouse Range of northern Idaho. A 1-m digital elevation model (DEM) was generated for the Palouse Range using light detection and ranging (LiDAR) data and resampled to 10-, 15-, 20-, and 30-m grid resolutions. Terrain attributes derived from these DEMs were used to model volcanic ash mantle presence or absence, thickness, and degree of mixing using classification and regression trees. Model accuracy for ash presence was assessed using 572 data points collected by the NRCS as part of a soil survey update. Overall, elevation was the single variable most related to the presence or absence, degree of mixing, and thickness of a volcanic ash mantle; other terrain attributes had less predictive value in modeling ash mantle characteristics. The 30-m grid resolution provided the best model of ash presence or absence, with 78% accuracy, indicating good promise for digitally mapping Andisols and related soils across the region. The various grid resolutions had little effect on the outcome and predictive ability of the models, and the overall accuracy of the models varied by only 2%. Moister, higher elevation plant communities provide a protective forest canopy and thick litter layer, which result in a relatively undisturbed ash mantle. At lower elevation where forest canopy is less dense, ash mantles are thinner, highly mixed, or absent.

"Clade 1") (Hymenoptera: Mymaridae) is a new association of the glassy-winged sharpshooter (GWSS), Homalodisca vitripennis (Germar) (Cicadellidae) and a candidate for its biological control in California, USA. In Argentina, G. sp. "Clade 1" was screened in the laboratory (no-choice tests) and in the field (multiple choice tests) against eggs of 32 Auchenorrhyncha host species and other four potential hosts unrelated to sharpshooters. In no-choice assays, it parasitized only eggs within the leafhopper tribe Proconiini. In contrast, in the long term field tests, it emerged not only from eggs of the Proconiini but also from two species of Cicadellini at low numbers (five wasps out of 698 exposed eggs). Two interpretations arise from the results: (1) Host associations of G. sp. "Clade 1" are restricted to the Proconiini whereas field parasitization of the Cicadellini species were false positive, or (2) G. sp. "Clade 1" parasitizes also some Cicadellini species and its rejection in the laboratory was a false negative. Both interpretations are discussed. Insect motivation could be the explanation for the negative results in the no-choice tests. On the other hand, in the more natural field situations, the host selection process and oviposition behavior should not have been affected and host range would be more realistic.

Tilapia were exposed to approximately 21 mg/l nitrite-N after 5 and 10 weeks of feeding to determine the effect of dietary NaCl supplementation on resistance to nitrite toxicity. Fish were sampled before (baseline, pre-exposure) and after 24 h nitrite exposure to determine the effects of dietary NaCl on mortality, hematology (hematocrit, hemoglobin, and methemoglobin), and plasma electrolyte dynamics (nitrite, chloride, sodium, and potassium). After 10 weeks of feeding, tilapia were also challenged with Streptococcus iniae to determine the effect of sodium chloride on immunity. Tilapia fed with the NaCl-supplemented diet had significantly higher weight gain compared with the control group, which was associated with a significant increase in feed intake in the NaCl group. Mortality from nitrite exposure was lower in tilapia fed with the NaCl-supplemented diet compared with the control group at 5 and 10 weeks, but the differences were not significant. However, dietary NaCl supplementation caused a significant decrease in plasma nitrite levels after nitrite exposure. The dietary reduction in nitrite may be related to the increase in plasma chloride in the 6% NaCl-supplemented fish. A direct link between the effects of dietary NaCl supplementation on methemoglobin (MetHb) could not be established. Tilapia in this study were subjected to acute nitrite toxicity. Dietary sodium chloride may be more effective in protecting against nitrite toxicity at lower levels of nitrite, but the conditions at which it proves to be effective may be limited and requires further investigation. Feeding NaCl to tilapia did not affect susceptibility to S. iniae or immune function, but nitrite exposure cause a stress-related reduction in non-specific immune function. This is the first study to examine the effects of dietary salt on nitrite toxicity in tilapia.

This study investigated the dynamic loads of Hg from the Cedar-Ortega Rivers watershed into the Lower St. Johns River (LSJR), Florida, USA, using the better assessment science integrating point and nonpoint sources (BASINS)-hydrologic simulation program-FORTRAN (HSPF) model. Materials and methods: The site-specific BASINS-HSPF model was developed for dynamic loads of Hg based on watershed, meteorological, and hydrological conditions. The model was calibrated and validated with existing field data. It was then applied to predict the daily and annual loads of Hg from the watershed outlet into the LSJR in response to rainfall events and water fluxes. Results and discussion: In general, the predicted average daily total Hg flux during the 10-year simulation period was about 0.69 gha super(-1) year super(-1). This finding was within the range of 0.22-1.41 gha super(-1) year super(-1) reported in the Florida Everglades area. Simulations further revealed that the effects of rainfall events on Hg loading were significant, particularly in a very wet period. A maximum total Hg flux was predicted during this wet period at a rate of 122.59 gha super(-1) year super(-1). Conclusions: Results from this study provide a useful case study on estimating Hg contamination in watersheds. The approaches used in this study could be transferred to estimate the dynamic loads of Hg in watersheds from other regions.

On average, the Australian model identifies major-invaders more accurately than it does non-invaders (90% vs. 70% accuracy). While this difference in performance emphasizes protection, the overall accuracy of the model will be determined by its performance with non-invaders because the frequency of invasive species among new plant introductions is relatively low. In this study, we develop a new weed risk assessment model for the entire United States that increases non-invader accuracy. The new screening tool uses two elements of risk, establishment/spread potential and impact potential, in a logistic regression model to evaluate the invasive/weedy potential of a species. We selected 204 non-invaders, minor-invaders, and major-invaders to develop and validate the new model, and compare its performance to the Australian model using the same set of species. Performing better than the Australian model, our new model accurately identified 94.1% of major-invaders and 97.1% of non-invaders, without committing any false positives or false negatives. The new secondary screening tool we developed reduced the number of species requiring secondary evaluation from 22 to 12%. We expect that the new weed risk assessment model should significantly enhance the United State's timeliness and accuracy in regulating potential weeds.

In mixed-grass prairie, invasive plants are often successful in relatively wet, nitrogen-rich areas, and areas protected from grazing. Dalmatian toadflax, a common invader of mixed-grass prairie, can also be favored by high water and nitrogen availability, but is thought to be relatively unpalatable to cattle, and therefore favored by grazing. We used spatially-adjusted model selection techniques to quantify relationships between toadflax cover (measured using very high-resolution aerial imagery), and relative snow deposition (estimated with a blowing snow model), slope, aspect, soil texture, and grazing intensity (estimated by proximity to water tanks). Toadflax was common throughout the 400 ha study site, occurring in 742 of 1,861 images. Toadflax cover was high on steeper slopes, particularly those with southern aspects. These two topographic variables were more effective in explaining toadflax distribution than modeled snow deposition, suggesting that factors other than snow deposition cause toadflax invasion on south-facing slopes. Toadflax cover was also high in areas further from water tanks, indicating that grazing may inhibit toadflax invasion. More broadly, this result suggests that grazing can reduce invasion of even relatively unpalatable species in ecosystems with long evolutionary histories of grazing.

Genetic marker development for marker-assisted selection (MAS) is critical for the success of cacao breeding for disease resistance and yield. To develop conserved ortholog set II (COSII) single-nucleotide polymorphism (SNP) markers for MAS in cacao, we have used three strategies and three types of cacao genetic and sequence data to identify and map 98 cacao COSII genes. The resources available at the time these studies were first undertaken dictated the strategy utilized. For the first strategy, SNPs were identified using cacao expressed sequence tags homologous to COSII sequences. Strategy II utilized a leaf transcriptome of cacao genotype "Matina 1-6" and Strategy III the genomic sequence of a 3-Mb region of "Matina 1-6" linkage group 5 associated with an important quantitative trait locus (QTL) for resistance to black pod. We have identified SNP markers for 83 of the 98 mapped COSII genes, and 19 of these SNP markers co-locate with QTLs. These COSII SNP markers, the first identified for cacao, will be used for genotyping and off-typing in cacao breeding programs and employed for genetic mapping and syntenic studies to trace co-location of genes regulating traits of importance between cacao and other species.

AN - 926891908; 16378362 AB - This study was designed to test the hypothesis that desert ant species that build nests that remain viable at a particular point in space for more than a decade produce soil conditions that enhance microbial biomass and functional diversity. We studied the effects of a seed-harvester ant, Pogonomyrmex rugosus, and two generalist ant species, Aphaenogaster cockerelli and Myrmecocystus depilis, on soil microbial communities. Microbial biomass was higher in P. rugosus-modified soils than in reference soils when soil water content was higher than 3%. Microbial biomass was either higher in reference soils or exhibited no difference in reference soils and nest-modified soils of A. cockerelli and M. depilis. There were differences in microbial functional diversity and microbial community level physiological profiles (MicroResp method) between ant-nest-modified and reference soils of the three ant species on some sampling dates. Temporal patterns of soil microbial communities associated with the ant species resulted from differences in soil moisture, density, and species composition of the annual plant communities associated with the ant nests and in reference areas. Differences in annual plant communities associated with ant nests and surrounding areas resulted in different chemical inputs into the soil organic-matter pools. This study shows that generalizations about the effects of long-lived ant nests on soil biota in arid regions must consider feeding behaviors of the ant species and temporal patterns of rainfall.

Retaining postharvest crop residues as soil surface cover is a primary method for controlling wind and water erosion; accordingly, erosion prediction models are highly sensitive to the amount of surface residue retained as soil cover. Traditionally, crop biomass calculations and erosion prediction models used expected or modeled crop yields and a fixed residue/grain index (R/G Index) value to determine residue quantity. Literature search indicated that cereal breeding efforts that emphasize yield have reduced the amount of residue for each unit of grain produced. In order to fulfill our objective of improving the relationship between grain yield and residue production, we assembled and examined a large set of regional crop yield and residue production data collected in research plot studies, on-farm field studies, and in available literature from eastern Washington and northcentral Oregon. Results of the study indicated that the R/G Index varies with yield. We also found that residue production versus grain yield for major nonirrigated crops of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) cereals, as well as for annual legumes and brassicas, can be fit with a linear relationship with a positive intercept and that the slope and intercept of the line are crop specific. Parameter values for specific crops are given. Using the historical fixed R/G Index can result in overestimating residue production of high-yielding winter wheat by as much as 35% and underestimating residue production for low spring wheat yields by as much as 66%. The results provide improved residue-to-grain yield relationships for use in water and wind erosion prediction models applied to the conditions of the Inland Pacific Northwest and adjacent areas. They provide a basis for estimating crop residue production in the region, and in conjunction with carbon sequestration models, a basis for determining if and where residues can be harvested for biomass in the region.

Field studies were conducted near Stoneville, Mississippi, on a Dundee silty clay loam in 2006 and 2007 to evaluate sediment, water, and metolachlor (2-chloro-N-[2-ethyl-6-methylphenyl]-N-[2-methoxy-1-methylethyl] acetamide) loss in narrow (38 cm [15 in]) and wide-row (102 cm [40 in]) cotton. One day after a postemer-gence metolachlor application over four- to six-leaf stage cotton, 60 mm h super(-1) (2.4 in hr super(-1)) of simulated rainfall was applied until 25 min of runoff was generated per plot. Sediment loss, regardless of year, was at least 38% lower from narrow-row than wide-row cotton. Depending on year, planting cotton on narrow rows either had no effect or reduced cumulative runoff by 25%, compared to the wide-row system. Cumulative metolachlor loss was 27% higher in narrow-row relative to wide-row cotton in 2006, but the trend was reversed in 2007. Our results indicate that nearly flat seedbeds in narrow-row systems can reduce sediment loss relative to wide-row cotton planted on slightly raised seedbeds. Moreover, planting cotton in narrow rows rather than wide rows may reduce the loss of metolachlor applied postemergence if cumulative runoff is reduced in the narrow-row system and factors governing mixing-zone pesticide concentrations are similar between row spacings, primarily canopy coverage, and antecedent soil moisture conditions.

Solutions of caproic, caprylic, capric and lauric acids dissolved in potassium hydroxide (KOH) were supplemented with 0, 5 or 10mM of EDDS and adjusted to pH 11.0 with citric acid. Wells made in agar media seeded with one of nine bacterial isolates were filled with FA-KOH or FA-KOH-EDDS solutions. After incubation of agar plates, zones of inhibition of bacterial growth around the agar wells were measured. Results indicated that caproic-KOH-EDDS and caprylic-KOH-EDDS inhibited growth of more bacterial isolates than caproic-KOH and caprylic-KOH, respectively. Although, capric-KOH and lauric-KOH produced zones of inhibition of all nine bacterial isolates, significantly (P less than or equal to 0.05) larger zones of inhibition were produced by capric-KOH-EDDS and lauric-KOH-EDDS. Findings of this study indicate that mixtures of FA-KOH-EDDS possess greater antibacterial activity than FA-KOH. Research demonstrates that supplementing mixtures of FA-KOH with EDDS increases the antibacterial activity of these antimicrobial surfactants. Similar results have been produced with FA-KOH supplemented with ethylenediaminetetraacetic acid (EDTA). However, EDTA is a man-made, nonbiodegradable chelator, whereas EDDS is a natural biodegradable chelator. Therefore, EDDS may be used as an alternative for EDTA in formulations of FA-KOH currently being examined as novel sanitizers for decreasing microbial contamination associated with poultry processing. Since EDDS is biodegradable, use of this chelator will not cause concerns of environmental pollution associated with the use of EDTA.

Aflatoxin contamination of pistachio nuts is a serious problem for many producing countries. The development of biological control methods based on ecological parameters is an environmentally friendly approach. Thirty-eight Aspergillus flavus isolates collected from a pistachio orchard in California (CA) were analyzed for production of aflatoxin (AF), cyclopiazonic acid (CPA), vegetative compatibility groups (VCGs), and mating types. All aflatoxigenic isolates produced both AFB sub(1) and CPA. The most toxigenic one was CA28 which produced 164 mu g AFB sub(1) per 5 ml PDA fungal culture and small sclerotia (S strain, sclertoium size less than 400 mu m). The other aflatoxigenic strains produce AFB sub(1) ranging from 1.2 mu g to 80 mu g per 5 ml fungal culture. Twenty-one percent of the CA isolates produced AFB sub(1), 84% produced CPA and half formed sclerotia on at least one of three tested media. The 38 CA isolates formed 26 VCGs, 6 of which had two or more isolates and 20 contained single isolates. The S strain isolates belong to 4 different VCGs. Genomic profiling by a retrotransposon DNA probe revealed fingerprint patterns that were highly polymorphic. The predicted VCGs (Pred-VCGs) based on a similarity coefficient >80% matched the VCGs of multiple isolates determined by complementation. All isolates within a VCG had the same mating-type gene of either MAT1-1 or MAT1-2. Uncorrected and VCG-corrected MAT1-1 and MAT1-2 among the isolates were equally distributed.

A three-year study of water chemistry, fish, and physical habitat in the Big Sunflower River in northwestern Mississippi coupled with continuously logged physicochemical and hydrology data provided by others showed prolonged periods of hypoxia associated with higher flows. Fish species richness was directly related to dissolved oxygen (DO) concentration (r super(2) = 0.35, p = 0.00004), and ordination using nonmetric multidimensional scaling (NMS) indicated strong association between fish community structure and DO. Low-head weirs supported relatively dense and diverse fish communities and thus provided local habitat enhancement, but may create stagnant zones upstream due to backwater effects that exacerbate low DO problems. Although hypoxia has been reported for some lightly degraded rivers and floodplains, our observations suggest hypoxia in Big Sunflower River and similar systems alters fish species composition and should be remediated. Cost-effective remediation will require better understanding of autotrophic and heterotrophic processes that control DO and the relationship of these processes to discharge.

A panel of eight simple sequence repeat (SSR) markers was developed and used to genetically characterize 'Ca. L. solanacearum' strains obtained from ZC-affected potato plants in the United States and Mexico. The multilocus SSR markers in this study effectively differentiated genotypes and estimated genetic diversity of 'Ca. L. solanacearum' strains. Genotype assignment analyses identified two major lineages of 'Ca. L. solanacearum' in the North American populations while only one lineage type was identified in Mexican population. No clear genetic structure was found among haplotypes based on geographical proximity or host. The high resolution power of the SSR marker system developed in this study provides a useful tool for genotyping closely related strains and tracking sources of the pathogen. Genotype information combined with epidemiological data will advance knowledge of ZC disease and will facilitate development of effective disease management.

Natural enemies of herbivorous pests in cropping systems often benefit from the presence of natural habitats in surrounding landscapes, as they provide key resources such as alternative hosts. However, any benefits from a biological control perspective may be dampened if this also enhances enemies at the fourth trophic level. Remarkably, studies of the influence of landscape structure on diversity and interactions of fourth trophic-level natural enemies are largely lacking. We carried out a large-scale sampling study to investigate the effects of landscape complexity (i.e. the proportion of non-crop habitat in the landscapes surrounding focal study areas) on the parasitoid communities of aphids in wheat and on an abundant extra-field plant, stinging nettle. Primary parasitoid communities (3rd trophic level) attacking the cereal aphid, Sitobion avenae, had little overlap with the communities attacking the nettle aphid, Microlophium carnosum, while secondary parasitoids (4th trophic level) showed high levels of species overlap across these two aphids (25 vs 73% shared species respectively), resulting in significantly higher linkage density and lower specialization for secondary than primary parasitoid webs. In wheat, parasitoid diversity was not related to landscape complexity for either primary or secondary parasitoids. Rates of primary parasitism were generally low, while secondary parasitism rates were high (37-94%) and increased significantly with increasing landscape complexity, although this pattern was driven by a single secondary parasitoid species. Overall, our results demonstrate that extra-field habitats and landscape complexity can differentially benefit fourth, over third, trophic level natural enemies, and thereby, could dampen biological control. Our results further suggest that fourth trophic-level enemies may play an important, yet understudied, role in linking insect population dynamics across habitat types.

In one cut flower field located in Martin County, FL, six cheeseweed mallow (Malva parviflora L.) plants were collected that had root-galling typical of infection by a root-knot nematode (Meloidogyne spp.). Field collected plants were used for species identification of the weed and maintained in the greenhouse for seed production. Several gravid female nematodes were extracted from field collected mallow roots and individually identified as Meloidogyne arenaria based on their esterase phenotype (PhastSystem, GE Healthcare) (1). A single egg mass was then extracted from the field collected mallow roots and inoculated onto a tomato plant (Solarium lycopersicum. 'Rutgers') grown in steamed builders sand in the greenhouse. The single egg mass culture was increased for 8 weeks, until galling was sufficient to produce adequate nematode inoculum to complete Koch's postulates on the original mallow host. Ten mallow plants were inoculated with single egg masses originally isolated from mallow and increased on tomato. Ten additional plants were maintained in the greenhouse as uninoculated controls. Inoculated and control mallow plants were grown in the greenhouse for 8 weeks, after which the roots were evaluated for galling, and root-knot nematode J2 were extracted from roots and soil and counted. All inoculated plants produced galled roots and control plants did not. Gravid females were extracted from mallow roots and identified as M. arenaria based on esterase phenotype as previously described. Ten gravid females for each DNA extraction were collected from mallow roots and DNA was isolated with the PowerSoil DNA Isolation Kit (MO BIO Laboratories. Inc.. Carlsbad. CA). Identification of M. arenaria was confirmed by using species-specific primers F5'-TCGAGGGCATCTAATAAAGG-3' and R5'-GGGCTG AATAATCAAAGGAA-3' (2) and F5'-TCGGCGATAGAGGTAAAT GAC-3' and R5'-TCGGCGATAGACACTACAACT-3' (4). which produced single amplicon bands of the expected size of 420 and 950 bp, respectively. This weed species has been reported as a host for M. javanica in Algeria and as an experimental host in Egypt (3). but this report, to our knowledge, constitutes the first documentation of Malva parviflora as a natural host of M. arenaria. The importance of weeds as hosts for plant parasitic nematodes cannot be over emphasized. As growers, particularly in Florida and California, continue to lose tools for broad-spectrum pest control, the ability of nematodes to reproduce on uncontrolled weeds will become increasingly important.

CA in March 2010. Initial symptoms consisted of small, dark brown-to-black lesions on leaves and stems. As disease progressed, lesions expanded in a linear fashion and eventually spread down the stems and into the bulbs. Once the disease reached the fennel bulbs, the plants were unmarketable. Eighteen, gram-negative, blue-fluorescing bacterial isolates were obtained on sucrose peptone agar from individual plants of two outbreaks from different fields in Salinas. The isolates were dome shaped on sucrose-amended media and produced necrotic lesions when injected into tobacco. Isolates were oxidase negative and did not rot potatoes or hydrolyze arginine. These reactions corresponded to Lelliot's group 1, which includes Pseudomonas syringae (2). The fennel isolates were identical to recently characterized isolates of P. syringae pv. apii from parsley grown in coastal California (1) and similar to the pathotype strain of P. syringae pv. apii according to DNA fragment banding patterns of amplicons generated from repetitive extragenic palindromic sequence (rep)-PCR using the BOXA1R primer. The isolates were distinct from the pathotype strain P. syringae pv. coriandricola. Like P. syringae pv. apii, the fennel isolates did not nucleate ice but did hydrolyze gelatine. Six isolates were tested for pathogenicity in each of two independent experiments with a total of six replications per isolate. Healthy, potted fennel plant stems of a proprietary cultivar were pierced once with insect display pins that had been dipped into bacterial colonies grown for 48 h on nutrient agar. Control stems were inoculated with sterile pins. Plants were incubated for 48 h at 100% relative humidity and then held in a greenhouse. After 4 to 6 days, inoculated fennel plants developed symptoms similar to those originally observed in the field. Bacteria isolated from surface-disinfested symptomatic tissue were fluorescent and identical to strains used to inoculate plants as evaluated by rep-PCR, thus fulfilling Koch's postulates. Control plants remained symptomless. To our knowledge, this is the first report of this pathogen causing a disease on fennel; the disease has been named bacterial streak. The disease occurred in three fields in 2010 and incidence was <1% in each case. Similar symptoms were also observed on fennel in the 2011 season in at least two fields. Previously, the host range of P. syringae pv. apii was reported to be restricted to celery. This research expands the natural host range of P. syringae pv. apii; thus, care should be taken in choosing Apiaceae crops for plantings subsequent to the occurrence of this pathogen.

It is of Meso-america origin and now is grown widely in the Western Hemisphere. In 2011, 2% of commercially grown tomatillo plants in San Benito County, California exhibited severe stunting with foliage showing mosaic symptoms and leaf distortion. The fruits on infected plants were mottled and unmarketable. Flexuous filamentous-shaped virus particles of 800 to 850 nm long and 11 to 12 nm wide were observed from sap of the symptomatic plants with a transmission electron microscope. Sap from the diseased tomatillo plants reacted positively in an immunostrip assay for potyvirus (Agdia Inc.. Elkhart, IN), indicating a potyvirus was associated with the disease. The causal agent was mechanically transmitted from the diseased field plants to six virus-free greenhouse tomatillo plants and all inoculated plants induced identical symptoms. The causal agent was also transmitted to Chenopodium quinoa and C. murale (chlorotic local lesions) and Nicotiana clevelandii, N. tabacum, and Physalis wrightii (systemic symptoms). The disease was also transmitted to tomatillo plants by the green peach aphid (Myzus persicae) in a nonpersistent manner (1-min acquisition access period and 1-min transmission access period with no latent period). To further identify the causal agent, total nucleic acids were extracted by a cetyltrimethylammoniumbromide (CTAB) method (2) and tested by reverse transcription-PCR using potyvirus degenerate primers CIFor and CIRev (1). An amplicon of approximately 700 bp from the diseased tomatillo was cloned and sequenced. Analysis of the 631 -bp partial CI sequence (GenBank Accession No. JN601884) showed that the virus had 93.6% nucleotide identity and 100% amino acid identity with cognate regions of Turnip mosaic virus (TuMV) (GenBank Accession No. D10927). Our results indicated that the disease was caused by TuMV. To our knowledge, this is the first report of TuMV in tomatillo. Since TuMV has a wide host range and is readily transmitted by green peach aphids, TuMV could be a new threat to tomatillo production in California.

CA in May. 2011 were found to be exhibiting yellowing, chlorotic sectors and spots on leaves, resulting in unmarketable plants. Dodder (Cuscuta spp.) was present in one of the fields, but was not visibly associated with symptomatic plants. Total nucleic acid was extracted from four symptomatic and three asymptomatic basil plants, as well as from the dodder plant with the RNeasy Plant Mini Kit (Qiagen. Valencia. CA). Nucleic acid extracts were tested by reverse transcription (RT)-PCR for the presence of Alfalfa mosaic virus (AMV) using primers designed to amplify a 350-nt region of the AMV coat protein gene (3). RT-PCR produced bands of the expected size in extracts from all symptomatic plants and the dodder sample. No amplification was obtained from symptomless plants. A 350-nt band amplified from one plant was gel-extracted, sequenced (TACGen. Richmond. CA), and confirmed to be AMV by comparison to sequences available in GenBank (Accession No. K02703). Although serological tests on an initial basil sample were negative for AMV by ELISA using antiserum produced against AMV by R. Larsen. USDA-ARS. Prosser. WA (unpublished). AMV was confirmed by ELISA and RT-PCR in symptomatic Nicotiana benthamiana. N. clevelandii, and Malva parviflora plants following mechanical transmission from basil source plants. The fields with AMV infections were located at opposite ends of the production region from one another, indicating widespread dispersal of AMV in the region. All AMV positive plants were adjacent to alfalfa. Two additional basil plantings in shade houses open to the outside environment did not have AMV symptomatic plants and were also confirmed negative by RT-PCR, but these plantings were at the extreme north end of Imperial Valley agriculture and well away from any alfalfa fields. At the time the basil plantations were sampled for AMV, no aphids were found in any plantations, but during the several weeks prior to finding the AMV-positive plants, cowpea aphid. Aphis craccivora Koch; pea aphid. Acyrthosiphon pisum Harris: blue alfalfa aphid. Acyrthosiphon kondoi Shinji: and spotted alfalfa aphid. Therioaphis maculata Buckton were colonizing Imperial Valley alfalfa fields, producing winged adults. AMV is transmitted by at least 14 aphid species (1). and most aphid populations increase during the late spring in this important desert agricultural region. The acquisition of AMV by dodder suggests the parasitic plant may serve as a vector of AMV within basil fields, although further study will be necessary for clarification. Significant acreage of basil is grown in the Imperial Valley. This acreage is surrounded by extensive and increasing alfalfa production totaling 55.442 ha (137.000 acres) in Imperial County and representing 21%increase in acreage over 2009 for the same region (2). To our knowledge, this is the first report of basil infected by AMV in California. The proximity of basil production to such a large alfalfa production region warrants the need for enhanced efforts at aphid management in basil production to reduce vector populations and reduce transmission to basil crops.

In the absence of sexual recombination, the ability to monitor mitochondrial haplotypes may provide an additional tool for identification of clonal isolates and analysis of population structure. To determine mitochondrial haplotypes for this species, seven mitochondrial loci spanning a total of 6.961 bp were sequenced for 62 isolates representing a geographically diverse collection of isolates with A1 and A2 mating type. Three of the regions were primarily intergenic regions between trnG and rns, rns and nad3, and nad6 and cox1, while the remaining loci spanned cox2, nad9, rps10, and secY coding regions and some of the flanking spacer regions. In total, 45 mitochondrial haplotypes were identified (75% of the total isolates examined) with differences due to single-nucleotide polymorphisms (SNPs, totaling 152 bp) and length mutations (17 indels >2 bp representing a total of 910 bp in length). SNPs were the predominate mutation in the four coding regions and their flanking intergenic regions, while both SNPs and length mutations were observed in the three primarily intergenic regions. Some of the length mutations in these regions were due to addition or loss of unique sequences while others were due to variable numbers of subrepeats (in the tmG-rns region, there were 3 to 12 copies of a 24-bp subrepeat sequence that differentiated 17 haplotypes). Network analysis of the haplotypes identified eight primary clades, with the most divergent clade representing primarily A1 isolates collected from Papua New Guinea. The isolate grouping in the network corresponded to mating type and previously published isozyme classifications, with three exceptions: a haplotype representing an A1 mating type (H29) was placed well within the A2 mating type haplotype grouping, one haplotype (H26) had isolates with two isozyme classifications, and one isozyme group was represented on separate network clades, suggesting that recombination has occurred in the past. Among the 62 isolates examined, several examples were identified of isolates recovered from different geographic regions having the same mitochondrial haplotype, suggesting movement of isolates via plant material. Analysis of the data set to determine whether fewer loci could be sequenced to classify haplotypes indicated that the tmG-rns and rns-nad6 loci would classify 87% of the haplotypes identified in this study, while additional sequencing of the nad9 or secY loci would further differentiate the remaining six haplotypes. Based on conservation of gene order in Phytophthora spp., the tmG-rns locus should be useful for mitochondrial haplotype classification in other species, as should the cox2, nad9, rps10, and secY loci. However, the rns-nad3 and nad6-cox1 loci span regions that can have a different gene order in some Phytophthora spp. JF - Phytopathology AU - Martin, F N AU - Coffey, MD AD - United States Department of Agriculture-Agricultural Research Service, 1636 East Alisal St., Salinas, CA 93905, USA, frank.martin@ars.usda.gov PY - 2012 SP - 229 EP - 239 VL - 102 IS - 2 SN - 0031-949X, 0031-949X KW - Microbiology Abstracts C: Algology, Mycology & Protozoology; Microbiology Abstracts A: Industrial & Applied Microbiology KW - Cyclooxygenase-2 KW - Data processing KW - Gene order KW - Mitochondria KW - Mating types KW - Cyclooxygenase-1 KW - Recombination KW - Differentiation KW - Spacer region KW - Classification KW - Haplotypes KW - Single-nucleotide polymorphism KW - Isoenzymes KW - Phytophthora cinnamomi KW - Population structure KW - Phytophthora KW - Mutation KW - A 01360:Plant Diseases KW - K 03450:Ecology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/923195757?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Amicrobiologya&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Phytopathology&rft.atitle=Mitochondrial+Haplotype+Analysis+for+Differentiation+of+Isolates+of+Phytophthora+cinnamomi&rft.au=Martin%2C+F+N%3BCoffey%2C+MD&rft.aulast=Martin&rft.aufirst=F&rft.date=2012-02-01&rft.volume=102&rft.issue=2&rft.spage=229&rft.isbn=&rft.btitle=&rft.title=Phytopathology&rft.issn=0031949X&rft_id=info:doi/ LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2012-02-01 N1 - Last updated - 2015-12-09 N1 - SubjectsTermNotLitGenreText - Cyclooxygenase-2; Gene order; Data processing; Mitochondria; Mating types; Cyclooxygenase-1; Differentiation; Recombination; Spacer region; Haplotypes; Classification; Single-nucleotide polymorphism; Isoenzymes; Population structure; Mutation; Phytophthora cinnamomi; Phytophthora ER - TY - JOUR T1 - Resistance to Alternaria solani in Hybrids Between a Solanum tuberosum Haploid and S. raphanifolium AN - 923195748; 16329340 AB - Early blight of potato (Solanum tuberosum). caused by the foliar fungal pathogen Alternaria solani, is a major cause of economic loss in many potato-growing regions. Genetic resistance offers an opportunity to decrease fungicide usage while maintaining yield and quality. In this study, an early blight resistant clone of the diploid wild species S. raphanifolium was crossed as a male to a haploid (2n=2x) of cultivated potato. Hybrids were backcrossed to both parents. Eight families were created and evaluated for early blight resistance in the field. Families created by backcrossing to the wild species parent exhibited significantly lower relative area under the disease progress curve means than those from backcrossing to the cultivated parent, leading to the conclusion that S. raphanifolium contributes genes for early blight resistance. The mechanism of resistance in S. raphanifolium is unique because A. solani could not be recovered from lesions. Clones were identified with high levels of resistance and adaptation to the photoperiod of a temperate production region.

Cell-free extracts from the bacterial phytopathogens Brenneria rubrifaciens, B. salicis, and B. nigrifluens induced production of the red pigment rubrifacine in the B. rubrifaciens bruI insertional mutant Br-212. Analysis of the bruI locus identified an adjacent open reading frame, designated bruR, with homology to lixR. High-performance liquid chromatography and mass spectrometry analysis of ethyl acetate extracts from wild-type B. rubrifaciens and Eschehchia coli expressing the bruI gene identified two acyl homoserine lactone (AHL) peaks, N-(3-oxohexanoyl)-homoserine lactone (3OC6HSL) and N-hexanoyl-homoserine lactone (C6HSL). Addition of synthetic 3OC6HSL and C6HSL at 10 mu M to the bruI mutant, strain Br-212, induced rubrifacine production and the ability to elicit a hypersensitive reaction (HR) in tobacco leaves. Synthetic C6HSL was less effective at inducing pigment production than 3OC6HSL at 10 mu M. The bruI mutant Br-212 did not produce detectable AHLs, indicating that C6HSL and 3OC6HSL are the major AHLs produced by this species. The AHLs N-heptanoyl-DL-homoserine lactone (C7HSL). N-octanoyl-DL-homoserine lactone (C8HSL), and N-(3-oxooctanoyl)-DL-homoserine lactone (3OC8HSL) also induced pigment production in Br-212 and restored its ability to elicit an HR in tobacco, suggesting that cross-talk with other bacterial species may be possible.

This research was designed to improve the germination of sand bluestem (Andropogon hallii Hack.) populations 'AB-medium Syn-0' and 'CD-tall Syn-0' at low water potentials. Two cycles of recurrent selection were used to develop populations 'AB-medium Syn-1', 'AB-medium Syn-2', 'CD-tall Syn-1' and 'CD-tall Syn-2'. Cycle 1 consisted of germinating 3500 open-pollinated seeds of each Syn-0 population in a -0.8MPa D-mannitol solution for seven days. All germinated seeds (approximately 250 of each population) were selected to create the Syn-1 populations. Cycle 2 selection was similar to Cycle 1, except that Syn-1 populations were used to create Syn-2 populations. To test the effects of selection, four 50-spikelet samples of the six populations were germinated at -0.8MPa for seven days. Germination of Syn-1 seeds was 6.7% higher than that of Syn-0 seeds, and Syn-2 seeds were 10.2% higher than that of Syn-1 seeds. Thus, it was possible to select for increased seed germination of sand bluestem Syn-0 populations at the water potential used herein.Original Abstract: With 1 table JF - Plant Breeding/Zeitschrift fuer Pflanzenzuchtung AU - Springer, Tim L AD - USDA-Agricultural Research Service, Southern Plains Range Research Station, 2000 18th Street, Woodward, OK 73801-5415, USA, E-mail: tim.springerrs.usda.gov Y1 - 2012/02// PY - 2012 DA - Feb 2012 SP - 198 EP - 202 PB - Wiley-Blackwell, 111 River Street Hoboken NJ 07030-5774 United States VL - 131 IS - 1 SN - 0179-9541, 0179-9541 KW - Biotechnology and Bioengineering Abstracts KW - Germination KW - Mannitol KW - Plant breeding KW - Sand KW - Seed germination KW - Seedlings KW - Seeds KW - Water potential KW - Andropogon hallii KW - W 30930:Agricultural Applications UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/920807852?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Abiotechresearch&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Plant+Breeding%2FZeitschrift+fuer+Pflanzenzuchtung&rft.atitle=Recurrent+selection+for+increased+seed+germination+in+sand+bluestem+%28Andropogon+hallii%29&rft.au=Springer%2C+Tim+L&rft.aulast=Springer&rft.aufirst=Tim&rft.date=2012-02-01&rft.volume=131&rft.issue=1&rft.spage=198&rft.isbn=&rft.btitle=&rft.title=Plant+Breeding%2FZeitschrift+fuer+Pflanzenzuchtung&rft.issn=01799541&rft_id=info:doi/10.1111%2Fj.1439-0523.2011.01899.x LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2012-02-01 N1 - Document feature - figure 0 N1 - Last updated - 2012-06-18 N1 - SubjectsTermNotLitGenreText - Germination; Seeds; Mannitol; Sand; Seed germination; Water potential; Plant breeding; Seedlings; Andropogon hallii DO - http://dx.doi.org/10.1111/j.1439-0523.2011.01899.x ER - TY - JOUR T1 - Trapping spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), with combinations of vinegar and wine, and acetic acid and ethanol AN - 920796011; 16238775 AB - Recommendations for monitoring spotted wing drosophila (SWD) Drosophila suzukii (Matsumura) are to use either vinegar or wine as a bait for traps. Traps baited with vinegar and traps baited with wine, in field tests in northwest Oregon, captured large numbers of male and female SWD flies. Numbers of SWD trapped were significantly greater with a mixture of vinegar and wine compared with vinegar alone or wine alone. Attraction of SWD to vinegar and wine may be due in part to responses to acetic acid and ethanol evaporated from the two baits, respectively. Numbers of SWD captured in traps baited with 2% acetic acid in water were significantly greater than in unbaited traps, indicating a fly response to acetic acid. Very few flies were captured in traps baited with 10% ethanol in water. Traps baited with a combination of acetic acid and ethanol in water captured more SWD flies than traps baited with acetic acid or ethanol solutions alone. These results indicate a synergy of the two materials, and of the two chemicals, as lures for SWD. A comparison of a mixture of acetic acid with ethanol in water versus a mixture of vinegar with wine showed stronger fly attraction to the vinegar/wine mixture, indicating potential attractiveness of vinegar and wine volatiles in addition to acetic acid and ethanol.

Weighing lysimeters are expensive and, although accurate, are difficult to manage and afford little replication. Direct soil water measurement by coring is accurate enough, but plagued by spatial variability that induces unwanted variability in the change in soil water storage between dates, and is destructive and time/labor consuming. Here we focus on soil water sensing using the neutron probe and various electromagnetic (EM) sensors (capacitance, time domain reflectometry (TDR) and quasi-TDR) with respect to the relative levels of uncertainty in profile water content, change in soil water storage, and estimates of deep flux; and their impact on estimated ET and water use efficiency (WUE). Studies consistently showed errors up to and >0.05m3m-3 for capacitance sensors used in access tubes, which implied errors in soil water flux estimation of up to 50mmday-1, and calibrations that were so sensitive to soil bulk electrical conductivity ( sigma dc) and temperature that water content and change in storage estimates were rendered unreliable. Also, larger spatial variability of water contents reported by capacitance sensors was tied to the EM field penetration in structured soils around access tubes being non-uniform and influenced by the random arrangement of soil micro-scale water content, sigma |>dc and bulk density distribution. Thus, we recommend that profiling sensor systems based on capacitance technology not be used for studies of water balance, ET and WUE, nor for irrigation scheduling. Recommended methods include the neutron probe, direct volumetric soil sampling and, in some cases, conventional time domain reflectometry with waveform capture and analysis. New sensor development efforts should focus on waveguide approaches using TDR technology.

AN - 918575180; 22051144 AB - Nutritional epigenetics has emerged as a novel mechanism underlying gene-diet interactions, further elucidating the modulatory role of nutrition in aging and age-related disease development. Epigenetics is defined as a heritable modification to the DNA that regulates chromosome architecture and modulates gene expression without changes in the underlying bp sequence, ultimately determining phenotype from genotype. DNA methylation and post-translational histone modifications are classical levels of epigenetic regulation. Epigenetic phenomena are critical from embryonic development through the aging process, with aberrations in epigenetic patterns emerging as aetiological mechanisms in many age-related diseases such as cancer, CVD and neurodegenerative disorders. Nutrients can act as the source of epigenetic modifications and can regulate the placement of these modifications. Nutrients involved in one-carbon metabolism, namely folate, vitamin B12, vitamin B6, riboflavin, methionine, choline and betaine, are involved in DNA methylation by regulating levels of the universal methyl donor S-adenosylmethionine and methyltransferase inhibitor S-adenosylhomocysteine. Other nutrients and bioactive food components such as retinoic acid, resveratrol, curcumin, sulforaphane and tea polyphenols can modulate epigenetic patterns by altering the levels of S-adenosylmethionine and S-adenosylhomocysteine or directing the enzymes that catalyse DNA methylation and histone modifications. Aging and age-related diseases are associated with profound changes in epigenetic patterns, though it is not yet known whether these changes are programmatic or stochastic in nature. Future work in this field seeks to characterise the epigenetic pattern of healthy aging to ultimately identify nutritional measures to achieve this pattern.

Microflora populations, color, antioxidant activity, total phenolics, and ascorbic acid were measured at 1, 7, 14 and 21 d of storage. Additionally, the inactivation of Escherichia coli O157:H7 by UV-C was determined. Results showed that UV-C doses of 0.45-3.15 kJ m super(-2 resulted in 0.67-1.13 log CFU g) super(-)1 reduction of E. coli O157:H7 inoculated on mushroom cap surfaces. UV-C radiation also reduced total aerobic plate counts by 0.63-0.89 log CFU g super(-1 on the surface of mushrooms. Although mushrooms treated with UV-C had more severe browning with increasing dosage after initial treatment, the control mushrooms also browned as indicted by lower L* and higher a* values after 21 d of storage at 4 degree C. In addition, the UV-C treatments apparently inhibited lesion development on the mushroom surface. During the first 7 d, irradiated mushrooms had lower antioxidant activity, total phenolics, and ascorbic acid content compared to non-radiated samples. However, irradiated mushrooms reached similar amounts of these nutrients as the control after 14 d of storage at 4 degree C. In summary, UV-C radiation could potentially be used for sanitizing fresh button mushrooms and extending shelf-life.)

A constructed wetland receiving agricultural runoff water was observed prior to, and for more than two years after, establishment. The excavated portion of this wetland was compared to an undisturbed, upland area and to an adjacent, natural, depressional, reference wetland. After construction the excavated cell was rapidly colonized by wetland plant species, including some exotic invasive weeds. Flourescein diacetate (FDA) hydrolysis and triphenyl tetrazolium chloride (TTC) dehydrogenase assays indicated that the soil microbial community was more active in the excavated wetland cell than either of the two reference areas. In 2003 and 2004 TTC activity was greater than twice as high in the constructed wetland than the reference wetland. FDA was greatly stimulated in the constructed wetland immediately after construction, but by 2004 the three systems were not significantly different. The soil microbial community of the constructed wetland rapidly decreased in the abundance of fungi and gram-negative bacteria and increased in gram-positive bacteria and overall bacteria, as measured by fatty acid methyl esters. These shifts in the microbial community were consistent with the differences noted between the communities of the upland system and the reference wetland. During the time of observation the constructed wetland did not sequester carbon relative to the upland system (P = 0.11) and did not significantly increase in carbon content (P = 0.41).

AN - 918033927; 22274863 AB - As part of a 2-yr study documenting the physiologic impact of grazing endophyte-infected tall fescue on growing cattle, 2 experiments were conducted to characterize and evaluate effects of grazing 2 levels of toxic endophyte-infected tall fescue pastures on vascular contractility and serotonin receptors. Experiment 1 examined vasoconstrictive activities of 5-hydroxytryptamine (5HT), α-methylserotonin (ME5HT; a 5HT(2) receptor agonist), d-lysergic acid (LSA), and ergovaline (ERV) on lateral saphenous veins collected from steers immediately removed from a high-endophyte-infected tall fescue pasture (HE) or a low-endophyte-infected mixed-grass (LE) pasture. Using the same pastures, Exp. 2 evaluated effects of grazing 2 levels of toxic endophyte-infected tall fescue on vasoconstrictive activities of (±)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane hydrochloride (DOI), BW 723C86 (BW7), CGS-12066A (CGS), and 5-carboxamidotryptamine hemiethanolate maleate (5CT), agonists for 5HT(2A),( 2B), 5HT(1B), and 5HT(7) receptors, respectively. One-half of the steers in Exp. 2 were slaughtered immediately after removal from pasture, and the other one-half were fed finishing diets for >91 d before slaughter. For Exp. 1, maximal contractile intensities were greater (P 91 d. Experiment 1 demonstrated that grazing of HE pastures for 89 to 105 d induces functional alterations in blood vessels, as evidenced by reduced contractile capacity and altered serotonergic receptor activity. Experiment 2 demonstrated that grazing HE pastures alters vascular responses, which may be mediated through altered serotonin receptor activities, and these alterations may be ameliorated by the removal of ergot alkaloid exposure as demonstrated by the absence of differences in finished steers.

This paper addresses the goal of reducing nitrogen in the Mississippi River through three objectives. First, the paper outlines an approach to the site-specific quantification of management effects on nitrogen loading from tile drained agriculture using a simulation model and expert review. Second, information about the net returns to farmers is integrated with the nitrogen loading information to assess the incentives to adopt alternative management systems. Third, the results are presented in a decision support framework that compares the rankings of management systems based on observed and simulated values for net returns and nitrogen loading. The specific question addressed is how information about the physical and biological processes at Iowa State University's Northeast Research Farm near Nashua, Iowa, could be applied over a large area to help farmers select management systems to reduce nitrogen loading in tile drained areas. Previous research has documented the parameterization and calibration of the RZWQM model at Nashua to simulate 35 management system effects on corn and soybean yields and N loading in tileflow from 1990 to 2003. As most management systems were studied for a 6 year period and in some cases weather had substantial impacts, a set of 30 alternative management systems were also simulated using a common 1974-2003 input climate dataset. To integrate an understanding of the economics of N management, we calculated net returns for all management systems using the DevTreks social budgeting tool. We ranked the 35 observed systems in the Facilitator decision support tool using N loading and net returns and found that rankings from simulated results were very similar to those from the observed results from both an onsite and offsite perspective. We analyzed the effects of tillage, crop rotation, cover crops, and N application method, timing, and amount for the 30 long term simulations on net returns and N loading. The primary contribution of this paper is an approach to creating a quality assured database of management effects on nitrogen loading and net returns for tile drained agriculture in the Mississippi Basin. Such a database would systematically extend data from intensively monitored agricultural fields to the larger area those fields represent.

This area evolved within the accretionary wedge of the Carpathians during the Neogene, and it was alsowas affected by Middle to Late Miocene thrusting of the External Carpathians. Morphometric analysis, longitudinal and transverse river valley profiles, analysis of basin and valley symmetries, and investigation of alluvial terraces were carried out on the northern Laborec River and its tributaries. This was done to detect a possible relationship between their river courses and any ongoing neotectonic activity, which is otherwise difficult to detect by methods of structural geology because of the poorly exposed area. The general topography of the basin is characterized by a stepwise inclination to the SW as a result of differential uplift and subsidence. The reorganization of the river network in the Laborec drainage basin was influenced by tectonic activity along the NE-SW up to N-S fault structures during the neotectonic phase (Pliocene-Quaternary). The movement along these fault structures is predominantly normal to transtensive. The obtained data assumes that the region is under approximately NE-SW oriented SHcompression and NW-SE trending S|>h tension. The Laborec drainage basin is characterized by a very high degree of asymmetry that sharply increases from the upper to the lower courses of the river. The right-bank tributaries of the Laborec River are <12km in length; however, the left-bank tributaries such as Vydranka, Ol'sava, Vyrava, Udava, and Cirocha Streams are up to 50km long with a high potential of headward erosion and capturing. The valley asymmetry is also very variable in the upper and lower portions of the basin. Based on these presented results, the ancient river thalweg was located along the axis of the Hostovice-Habura depression, and it was captured by the Ol'sava, Vyrava, and Udava Streams. The asymmetric pattern of the drainage basin is the result of active tectonics, the continual subsidence of the Transcarpathian Basin, and by the uplift of the Laborecka vrchovina and Bukovske vrchy Mts. These events caused rejuvenation of the headward erosion of streams in the southern part. Favorable lithology was also essential in the process of river capture.

The objectives of this research were to investigate the chemical and nutritional characteristics and determine effective separation methods of the peel and seed of commercial tomato pomace from hot and cold break processes. The chemical composition of pomace, including fatty acid content of the seed oil, and the nutritional quality, including amino acid profile of defatted seed, were determined. The impacts of dry and wet separation on physicochemical properties of the peel and seed were evaluated. Based on the results, the studied pomace samples were rich in nutrients, including fat (8.37% to 16.24%), protein (15.08% to 22.70%), insoluble dietary fiber (IDF) (48.49% to 64.75%), soluble dietary fiber (SDF) (8.91% to 10.04%), and lycopene (98.16 to 172.07 mg kg(-1)). The seed oil had total unsaturated fatty acid content up to 80.10%, and the defatted tomato seed contained six kinds of essential amino acids, with histidine, an essential amino acid for infants, as the most dominant (23.34%). Both the dry and wet separation methods were effective for separation of the studied pomace. However, wet separation caused significant loss of micronutrients.

Currently, the APEX (Agricultural Policy/Environmental extender) model is being used for this purpose in the USDA Conservation Effects Assessment Project (CEAP) Cropland National Assessment. In support of the CEAP modeling effort, APEX was calibrated and validated using a nine-year record (1999-2007) of crop yield, surface runoff, and tile outflow and an eight-year record (1999-2006) of soluble pendimethalin and fluometuron herbicide losses from fields in a cotton-peanut rotation located in the Atlantic Coastal Plain region of south-central Georgia. Conventional tillage and strip tillage were directly compared. Monthly surface runoff was calibrated by adjusting three variables: curve number index coefficient (CNIC), a driver of the USDA Natural Resources Conservation Service (NRCS) runoff curve number; runoff curve number for the average soil moisture condition 2 (CN2); and irrigation runoff ratio (IRR). Statistical performance criteria for monthly and annual results were r(2) > 0.5, NSE > 0.45, and PBIAS < 20%, based on prior modeling studies. Monthly runoff statistics showed r2 values of 0.62 to 0.82 and met satisfactory criteria between observed and simulated surface runoff for both tillage types, with Nash-Sutcliffe efficiency (NSE) values of 0.62 to 0.80 and PBIAS values within plus or minus 19% during the calibration and validation periods. Monthly subsurface lateral flow performance statistics for the strip-tilled plots were satisfactory during the calibration period but weak for the conventional tillage plots. Monthly performance statistics for fluometuron runoff for the conventional tillage plots were below satisfactory criteria. Other monthly statistics for fluometuron and pendimethalin losses were weak. Measured and predicted crop yield and annual runoff for both tillage systems were well aligned and met satisfactory statistical criteria. APEX performance was satisfactory for annual fluometuron soluble runoff for the conventionally tilled plots but not satisfactory for the strip-tilled plot with less runoff. The model's performance was unsatisfactory for annual subsurface lateral flow and fluometuron transport in subsurface lateral flow for both tillage systems. The percent bias statistical parameter (PBIAS) was within plus or minus 20% for all annual mean correlations, indicating that APEX effectively replicated annual means for crop yield, runoff, subsurface lateral flow, and pesticide losses. Measured and simulated results of conservation tillage effects were in close agreement for decreased water and pesticide runoff as well as increased subsurface lateral flow and associated fluometuron losses. Although fluometuron losses in subsurface lateral flow approximately doubled with conservation tillage, loading was still small compared to fluometuron in runoff from the conventionally tilled plots. Results demonstrate APEX's strength in simulating runoff in this landscape, but less satisfactory results were obtained for pendimethalin runoff, subsurface lateral flow, and fluometuron losses in subsurface lateral flow.

Although prescribed fire can reduce understory density, oak seedlings often fail to show increased vigor after fire, as the canopy remains intact. In this study, we examine the response of tree regeneration to a sequence of repeated prescribed fires followed by canopy gap formation. We sampled advance regeneration (stems >30 cm tall) in 52 gaps formed by synchronous mortality of white oak (Quercus alba L.); 28 gaps were in three burned stands and 24 gaps were in three unburned stands. Five years after gap formation, unburned gaps were being filled by shade-tolerant saplings and poles and were heavily shaded (7% of full sun). By contrast, tolerant saplings had been virtually eliminated in the burned gaps, which averaged 19% of full sun. Larger oak and hickory regeneration was much more abundant in burned gaps, as was sassafras, while shade-tolerant stems were equally abundant in burned and unburned gaps. Our results suggest that the regeneration of oak, particularly that of white oak, may be improved with multiple prescribed fires followed by the creation of moderate-sized canopy gaps (200-400 m super(2)).Original Abstract: La dominance des chenes diminue dans la region centrale de la foret feuillue et son couvert est graduellement remplace par celui d'arbres tolerants a l'ombre qui sont abondants dans le sous-bois des forets matures. Bien que le brulage dirige puisse reduire la densite des arbres du sous-bois, les semis de chene sont souvent incapables d'augmenter leur vigueur apres feu lorsque la canopee demeure intacte. Dans cette etude, nous evaluons la reaction de la regeneration des arbres a la suite de brulages diriges repetes qui ont precede la formation de trouees dans la canopee. Nous avons echantillonne la regeneration pretablie (plus de 30 cm de hauteur) dans 52 trouees formees par la mort synchrone de chenes blancs (Quercus alba L.). Vingt-huit trouees etaient situees dans trois peuplements brules alors que 24 trouees etaient situees dans trois peuplements non brules. Cinq ans apres la formation des trouees, les trouees des peuplements non brules etaient occupees par des gaules et des perches d'especes tolerantes a l'ombre et etaient fortement ombragees (7% de la pleine lumiere). A l'inverse, les gaules d'especes tolerantes a l'ombre avaient ete pratiquement eliminees des trouees des peuplements brules qui recevaient, en moyenne, 19% de la pleine lumiere. Une regeneration de grande taille de chene et de caryer etait beaucoup plus abondante dans les trouees des peuplements brules, tout comme le sassafras, alors que les individus tolerants a l'ombre etaient aussi abondants dans les trouees des peuplements brules que non brules. Nos resultats indiquent que la regeneration du chene, particulierement celle du chene blanc, peut etre amelioree a l'aide de brulages diriges multiples, suivis par la creation de trouees de taille moderee (de 200 a 400 m super(2)) dans la canopee.

As hyperspectral imagery is becoming more available, the number of possible VIs that can be calculated is overwhelmingly large. The objectives of this study were to examine spectral distance, spectral angle and plant abundance (crop fractional cover estimated with spectral unmixing) derived from all the bands in hyperspectral imagery and compare them with eight widely used two-band and three-band VIs based on selected wavelengths for quantifying crop yield variability. Airborne 102-band hyperspectral images acquired at the peak development stage and yield monitor data collected from two grain sorghum fields were used. A total of 64 VI images were generated based on the eight VIs and selected wavelengths for each field in this study. Two spectral distance images, two spectral angle images and two abundance images were also created based on a pair of pure plant and soil reference spectra for each field. Correlation analysis with yield showed that the eight VIs with the selected wavelengths had r values of 0.73-0.79 for field 1 and 0.82-0.86 for field 2. Although all VIs provided similar correlations with yield, the modified soil-adjusted vegetation index (MSAVI) produced more consistent r values (0.77-0.79 for field 1 and 0.85-0.86 for field 2) among the selected bands. Spectral distance, spectral angle and plant abundance produced similar r values (0.76-0.78 for field 1 and 0.83-0.85 for field 2) to the best VIs. The results from this study suggest that either a VI (MSAVI) image based on one near-infrared band (800 or 825 nm) and one visible band (550 or 670 nm) or a plant abundance image based on a pair of pure plant and soil spectra can be used to estimate relative yield variation from a hyperspectral image.

Despite the ubiquity of herbivore-microbe feeding associations, few studies examine how host plant phenotypes affect microbial symbionts of herbivores. We tested the hypothesis that chemical polymorphism in a plant population mediates the performance of nutritional microbial symbionts. We surveyed the composition of ponderosa pine resin in northern Arizona, USA, for variation in six monoterpenes, and we approximated four chemical phenotypes. We reared populations of an herbivorous tree-killing beetle (Dendroctonus brevicomis) in ponderosa pine host material, controlling for three monoterpene compositions representing an alpha -pinene to Delta -3-carene gradient. Beetles were reared in host material where the dominant monoterpene was alpha -pinene, Delta -3-carene, or a phenotype that was intermediate between the two. We isolated nutritional fungal symbionts (Entomocorthium sp. B) from beetle populations reared in each phenotype and performed reciprocal growth experiments in media amended to represent four "average" monoterpene compositions. This allowed us to test the effects of natal host phenotype, chemical polymorphism, and the interaction between natal host phenotype and chemical polymorphism on a nutritional symbiont. Three important findings emerged: (1) fungal isolates grew 25-32% faster when acquired from beetles reared in the intermediate phenotype; (2) the mean growth rate of nutritional fungi varied up to 44% depending on which monoterpene composition media was amended with; and (3) fungal isolates uniformly performed best in the intermediate phenotype regardless of the chemical composition of their natal host. The performance of nutritional fungi related to both the chemical "history" of their associated herbivore and the chemical phenotypes they are exposed to. However, all fungal isolates appeared adapted to a common chemical phenotype. These experiments argue in favor of the hypothesis that chemical polymorphism in plant populations mediates growth of nutritional symbionts of herbivores. Intraspecific chemical polymorphism in plants contributes indirectly to the regulation of herbivore populations, and our experiments demonstrate that the ecological effects of plant secondary chemistry extend beyond the trophic scale of the herbivore-plant interaction.

We censused birds and monitored nests in four forest types over an elevational gradient. We identified habitat patches homogeneous in terms of forest type, seral stage, and canopy cover and rated edges between adjoining patches as soft, moderate, or hard on the basis of relative differences in the suitability of adjacent patches. Brown Creepers were more abundant in sites with less high-contrast edge and more medium- and high-quality habitat. They avoided soft and moderate edges when selecting nest sites. Successful nests were in large-diameter trees and snags in forest with lower canopy closure and farther from moderate and hard edges than were unsuccessful nests. Clear negative responses to edge in terms of abundance, nest location, and nest survival were surprising because previous work has suggested that edge effects and the processes underlying them may differ in western coniferous forests because of their natural heterogeneity and because past forest management in the region resulted in fairly soft edges. The strength of the response was somewhat tied to the severity of the edge, although creepers avoided even soft edges. Hard edges were relatively rare and resulted primarily from natural discontinuities. Our results suggest that Brown Creepers should benefit from forest management that retains mature forest with minimal discontinuities, regardless of their source. Results also suggest that differences in relative habitat quality rather than differences in vegetation were responsible for observed patterns.

Because of the lack of studies that explain the hydraulics of concentrated flow on rangelands, cropland-based equations have typically been used for rangeland hydrology and erosion modeling, leading to less accurate predictions due to different soil and vegetation cover characteristics. This study investigates the hydraulics of concentrated flow using unconfined field experimental data over diverse rangeland landscapes within the Great Basin region, United States. The results imply that the overall hydraulics of concentrated flow on rangelands differ significantly from those of cropland rills. Concentrated flow hydraulics on rangelands are largely controlled by the amount of cover or bare soil and hillslope angle. New predictive equations for concentrated flow velocity (R (super 2) = 0.47), hydraulic friction (R (super 2) = 0.52), and width (R (super 2) = 0.4) representing a diverse set of rangeland environments were developed. The resulting equations are applicable across a wide span of ecological sites, soils, slopes, and vegetation and ground cover conditions and can be used by physically-based rangeland hydrology and erosion models to estimate rangeland concentrated flow hydraulic parameters.

Cooked chicken breast meats, surface-inoculated with a cocktail of L. monocytogenes, were subjected to NIR treatment. The surface temperature of the inoculated samples was increased to and then maintained at a temperature set point (62, 68 or 75C) for up to 8 min, depending on the temperature. On average, the overall rates of bacterial inactivation were 0.35, 0.89 and 1.6 log cycles/min for the samples treated at 62, 68 or 75C, respectively. In contrast, the bacterial inactivation rates were only 0.21, 0.53, 0.63 or 0.95 log-cycles/min for samples submerged under hot water maintained at 62, 68, 75 or 85C, respectively. NIR surface pasteurization process was convincingly more effective than the hot water immersion process to eliminate L. monocytogenes. Far-infrared (FIR) surface pasteurization, alone or in combination with hot water immersion (HWI) heating, has been used in the food industry to decontaminate ready-to-eat (RTE) meat surfaces immediately prior to final packaging. Near-infrared surface pasteurization provides another potentially faster alternative to FIR and HWI to eliminate L. monocytogenes on RTE meats.

AN - 902376651; 15909653 AB - Adoption of no-tillage in the northern Corn Belt has lagged behind other regions because of slow warming and drying of soils early in the spring coupled with a short growing season. Cold, wet soil can lead to seed damage resulting in poor stand establishment. Because of slow warming and drying, no-tilled soils are typically sown later than conventionally tilled systems thus often requiring the use of early maturing crop cultivars. Temperature-activated polymer seed coatings might allow soybean [Glycine max (L.) Merr.] to be sown earlier than normal under no-tillage while protecting seed against damage caused by cold, wet soil and perhaps allow the use of later maturing cultivars. These ideas were tested during 2005 and 2006 in west central MN on a Barnes loam no-tilled soil previously cropped in corn (Zea mays L.). Polymer-coated seed of a maturity group (MG) 0 and I soybean were sown as early as possible (early- to mid-April) and at an average recommended time (mid-May) for the study site. Only in 2005 did the polymer coating significantly increase emergence (p 0.0001), where maximum emergence of early sown polymer-coated seed of the MG 0 and I cultivars was 51 and 35% greater than their uncoated counterparts. Conversely, for the average sowing date in 2006, under unusually dry conditions, the polymer coating slowed seedling emergence and reduced maximum emergence, although yield was not affected. Laboratory incubations confirmed that the germination delay of soybean caused by the polymer-coating increased by decreasing initial osmotic moisture potentials. The MG I soybean out yielded the earlier maturing cultivar in both years, but sowing date did not have a significant effect either year. Results indicate that temperature-activated polymer-coated seed may reduce the risk of poor stand establishment in no-tilled soil in instances where low soil temperatures cause seed to remain in the soil for an extended time before emerging.

Silvicultural treatments are used to restore forest resilience, but little is known about their microclimate-mediated effects on fire behavior. We measured fire-related microclimate variables for two years before and after experimental, operational-scale application of fuels-reduction thinning and group selection treatments in a Sierra Nevada mixed-conifer forest. Measurements included air speed, temperature, and relative humidity; soil temperature and moisture; and dead fuel moisture. Wind gust speed increased moderately (average 0.7ms-1 or 31% increase) in thinned forest and sharply (average 2.5ms-1 or 128% increase) in group-selection openings. Surprisingly, treatments did not affect air temperature or humidity. Soil temperatures increased by a mean of 4 degree C in group openings but did not increase in thinned stands. Duff moisture in group selection openings was 72% of that in the control stands, but there were no effects on moisture in other fuel particle size classes, or in thinned stands. Soil moisture increased in group-selection openings at depths down to 0.7m but did not change in thinned stands. Fire spread simulation modeling with FMAPlus indicated that elevated wind speeds could increase the fire rate of spread, but that increases are moderate and largely linear rather than exponential across the observed range of wind gust speeds. In general our results suggest that group selection openings placed in high canopy cover, Sierran mixed-conifer forests are distinct microclimatic environments that will have slightly different fire behavior than the surrounding matrix due to higher surface temperatures and faster wind speeds. Current fuels-reduction thinning practices in dry western forests, however, will have minimal microclimatic-mediated influence on wildfire behavior, and there is little cause for concern about a faster rate of fire spread or drier fuels in such stands.

16197181 AB - Previous studies have suggested that lipid from nuts is more poorly absorbed than that from other food sources. If lipid from nuts is poorly absorbed, then the metabolisable energy contained in the nuts is less than that predicted by the Atwater general factors. A crossover feeding study was conducted in which sixteen volunteers consumed pistachios for 3 weeks as part of a controlled diet. Pistachio doses were 0, 42 and 84 g/d. Urine and faecal samples were collected, and urine, faeces and diet were analysed for N, fat, total dietary fibre, ash and combustible energy. Blood was also collected after each treatment period and analysed for plasma lipids. Energy value of pistachio nuts was calculated from differences in energy excretion during the different dietary treatments. The measured energy density of pistachios was found to be 22.6 kJ/g, which is 5 % less than the currently accepted energy value of 23.7 kJ/g, as calculated using the Atwater general factors. The pistachio nut intervention lowered LDL-cholesterol by 6 %, but did not significantly change plasma total cholesterol, HDL-cholesterol or TAG. In conclusion, pistachio nuts contain less metabolisable energy than that calculated from the Atwater general factors. Accurate information about metabolisable energy content of foods is important for reliable food labelling.

Combination of acceptable DMF solvating properties for HSs together with wide pore RP sorbent improved surface interactions of the analytes and suppressed influence of size-exclusion effects in RP-HPLC. Individual fractions collected from the RP-HPLC were off-line analyzed by size-exclusion chromatographic method (SEC) using 99/1 DMF/aqueous phosphate buffer pH 3.0 with Spheron HEMA 100 stationary phase filled in a 2.2 mm I.D. column. Both methods provided reproducibility of characterization profiles and robustness resulting from excellent reproducibility of HSs fraction retention times (+/-0.5% RSD) of peaks enforced by the step gradient shape. Obtained results indicate that the methods can be combined in a compatible, compact, automatic, 2D orthogonal separation system for fluorimetric characterization of such complicated natural substances as are examined humic acids and obtain so more information about their character.

AN - 916148059; 22142246 AB - Meadowfoam (Limnanthes alba L.) is a herbaceous winter-spring annual grown as a commercial oilseed crop. The meal remaining after oil extraction from the seed contains up to 4% of the glucosinolate glucolimnanthin. Degradation of glucolimnanthin yields toxic breakdown products, and therefore the meal may have potential in the management of soilborne pathogens. To maximize the pest-suppressive potential of meadowfoam seed meal, it would be beneficial to know the toxicity of individual glucolimnanthin degradation products against specific soilborne pathogens. Meloidogyne hapla second-stage juveniles (J2) and Pythium irregulare and Verticillium dahliae mycelial cultures were exposed to glucolimnanthin as well as its degradation products. Glucolimnanthin and its degradation product, 2-(3-methoxyphenyl)acetamide, were not toxic to any of the soilborne pathogens at concentrations up to 1.0 mg/mL. Two other degradation products, 2-(3-methoxymethyl)ethanethioamide and 3-methoxyphenylacetonitrile, were toxic to M. hapla and P. irregulare but not V. dahliae. The predominant enzyme degradation product, 3-methoxybenzyl isothiocyanate, was the most toxic compound against all of the soilborne pathogens, with M. hapla being the most sensitive with EC(50) values (0.0025 ± 0.0001 to 0.0027 ± 0.0001 mg/mL) 20-40 times lower than estimated EC(50) mortality values generated for P. irregulare and V. dahliae (0.05 and 0.1 mg/mL, respectively). The potential exists to manipulate meadowfoam seed meal to promote the production of specific degradation products. The conversion of glucolimnanthin into its corresponding isothiocyanate should optimize the biopesticidal properties of meadowfoam seed meal against M. hapla, P. irregulare, and V. dahliae.

16311585 AB - As geoscientists, we often perceive the production of a map or model to adequately define landslide hazard for an area as the answer or end point for reducing risk to people and property. In reality, the risk to people and property remains pretty much the same as it did before the map existed. Real landslide risk reduction takes place when the activities and populations at risk are changed so the consequences of a landslide event results in lower losses. Commonly, this takes place by translating the information embodied in the landslide hazard map into some change in policy and regulation applying to the affected area. This is where the dilemma arises. Scientific information generally has qualifications, gradations, and conditions associated with it. Regulations are necessarily written in language that tries to avoid any need for interpretation. Effectively incorporating geologic information into regulations and ordinances requires continued involvement with their development and implementation. Unless geoscientists are willing to participate in that process, sustainable risk reduction is unlikely to occur.

This method requires no modification of plasma and the working environment does not interfere with the determination of these analytes. The method allows simultaneous quantification of non-polar sevoflurane and its polar metabolite hexafluoroisopropanol (free, unconjugated form). It is characterized by high repeatability and sensitivity with the detection limit of 0.009 mg L-1 for sevoflurane and 0.018 mg L-1 for hexafluoroisopropanol and the linear range 0.050-150 mg L-1. The method was used to determine the concentration of sevoflurane and hexafluoroisopropanol in plasma samples of 7 patients undergoing general anesthesia with sevoflurane. The average concentration of sevoflurane and free hexafluoroisopropanol was 57.2 mg L-1 and 0.39 mg L-1, respectively. The method can be applied for clinical monitoring, as well as for analytical toxicology.

16506824 AB - Data points intensively sampling 46 North American biomes were used to predict the geographic distribution of biomes from climate variables using the Random Forests classification tree. Techniques were incorporated to accommodate a large number of classes and to predict the future occurrence of climates beyond the contemporary climatic range of the biomes. Errors of prediction from the statistical model averaged 3.7%, but for individual biomes, ranged from 0% to 21.5%. In validating the ability of the model to identify climates without analogs, 78% of 1528 locations outside North America and 81% of land area of the Caribbean Islands were predicted to have no analogs among the 46 biomes. Biome climates were projected into the future according to low and high greenhouse gas emission scenarios of three General Circulation Models for three periods, the decades surrounding 2030, 2060, and 2090. Prominent in the projections were (1) expansion of climates suitable for the tropical dry deciduous forests of Mexico, (2) expansion of climates typifying desertscrub biomes of western USA and northern Mexico, (3) stability of climates typifying the evergreen-deciduous forests of eastern USA, and (4) northward expansion of climates suited to temperate forests. Great Plains grasslands, and montane forests to the detriment of taiga and tundra climates. Maps indicating either poor agreement among projections or climates without contemporary analogs identify geographic areas where land management programs would be most equivocal. Concentrating efforts and resources where projections are more certain can assure land managers a greater likelihood of success.

Ideally, the agent reduces invader abundance to some acceptably low level, and the two coexist at low density with the agent providing continuous control over the long term. But the outcome may be complicated when the agent is attacked by native predators and parasites. We used a spatially explicit, discrete-time, individual-based, coupled plant-seed predator-parasitoid model to estimate the impact of the biocontrol agent Eustenopus villosus (a seed predator) on the invasive, annual weed Centaurea solstitialis, both with and without the generalist parasitoid Pyemotes tritici. We estimated the agent's ability to reduce plant density, spread rate, and population growth rate over 50 years. We used long-term demographic data from two sites in central California, USA, to parameterize the model and assess how populations in different climatic zones might respond differently to the agent and the parasitoid. We found that the biocontrol agent reduced plant density (relative to predictions for an uncontrolled invasion), but its impact on the invader's spread rate was modest and inconsistent. The agent had no long-term impact on population growth rate ( lambda ). Parasitism caused a trophic cascade, the strength of which varied between sites. At our coastal site, the parasitoid entirely eliminated the impact of the agent on the plant. At our Central Valley site, even when parasitized, the agent significantly reduced plant density and spread rate over several decades (although to a lesser degree than when it was not parasitized), but not invader lambda Surprisingly, we also found that the length of time the invader was allowed to spread across the landscape prior to introducing the agent (5, 25, or 50 years) had little influence over its ability to control the weed in the long term. This is encouraging news for land managers attempting to control invasive plants that have already established widespread, high-density populations. Unfortunately, our results also show that attack by the native generalist parasitoid had a larger influence over how effectively the agent reduced invader performance.

Onset of an acute lethal infection following inoculation with several pathogenic Leptospira species has been widely adopted for pathogenesis studies. An important exception is the outcome following inoculation of hamsters with live L. borgpetersenii serovar Hardjo, the primary cause of bovine leptospirosis and a cause of human infections. Typically, inoculation of hamsters with L. borgpetersenii serovar Hardjo fails to induce clinical signs of infection. In this study, the authors defined LD50 and ID50 for 2 strains of L. borgpetersenii serovar Hardjo: JB197 and 203. Both strains infected hamsters with ID50 values of approximately 1.5 x 102 bacteria yet differed in tissue invasion and interaction with leukocytes, resulting in widely divergent clinical outcomes. Hamsters infected with strain 203 established renal colonization within 4 days postinfection and remained asymptomatic with chronic renal infections similar to cattle infected with serovar Hardjo. In contrast, hamsters infected with strain JB197 developed a rapidly debilitating disease typical of acute leptospirosis common in accidental hosts (eg, humans) with an LD50 of 3.6 x 104 bacteria. Evidence that strain JB197 resides in both extracellular and intracellular environments during hamster infection was obtained. Development of models that result in chronic and acute forms of leptospirosis provides a platform to study L. borgpetersenii pathogenesis and to test vaccines for the prevention of leptospirosis.

Neonatal lambs (n = 32; age = 7.1 plus or minus 1.2 d; BW = 6.8 plus or minus 1.0 kg) and yearling ewes (n = 44; BW = 74.8 plus or minus 5.6 kg) were used in 2 experiments. In both experiments, lambs and ewes were randomly assigned to 1 of 4 groups, and groups were randomly assigned to 1 of 4 treatments. In Exp. 1, neonatal lambs were given single, aqueous, oral doses of saline (control; NaCl, 30 mg.kg of BW-1) or 30, 60, or 90 mg of NaClO3.kg-1 of BW. At 25.9 plus or minus 1.3 h after treatment, lambs were euthanized, and intestinal contents were collected aseptically. In Exp. 2, ewes were given single, aqueous, oral doses of saline (NaCl, 150 mg.kg of BW-1) or 150, 300, or 450 mg of NaClO3.kg-1 of BW. At 24.0 plus or minus 0.8 h after treatment, fecal samples were collected aseptically from the rectum of each ewe. For both experiments, generic E. coli were enumerated from intestinal contents and feces within 4 to 12 h after collection. In Exp. 1, the effect (P = 0.08) of NaClO3 on the presence of generic E. coli in colon contents was dose-dependent. This effect was linear (P < 0.01) and negative, which indicated that as NaClO3 dose increased, generic E. coli that could be isolated from colon contents decreased. Specifically, lambs dosed with 60 and 90 mg of NaClO3.kg-1 of BW had fewer E. coli cfu.g-1 of content than control lambs (P < 0.06). Lambs dosed with 90 mg of NaClO3.kg-1 of BW had fewer E. coli cfu.g-1 of content than lambs dosed with 30 mg of NaClO3.kg-1 of BW (P = 0.09). Sodium chlorate dose did not influence (P = 0.58) the presence of generic E. coli in contents collected from the cecum. In Exp. 2, the effect (P < 0.0001) of NaClO3 on the presence of E. coli in fecal contents from ewes was dose-dependent. This effect was quadratic (P < 0.0001) and negative; ewes dosed with 150, 300, and 450 mg of NaClO3.kg-1 of BW had fewer E. coli cfu.g-1 of feces than control ewes. No differences in E. coli cfu.g-1 of feces were detected between NaClO3 treatments (P = 0.88 to 0.97). Based on these results, a single oral dose of at least 60 and 150 mg of NaClO3.kg-1 of BW in neonatal lambs and yearling ewes, respectively, significantly decreased the presence of generic E. coli in contents from the lower intestine.

Taxonomic characterization of Streptomyces strains has been a challenge due to the large number of described species, greater than any other microbial genus, resulting from academic and industrial activities. The methods used for characterization have evolved through several phases over the years from those based largely on morphological observations, to subsequent classifications based on numerical taxonomic analyses of standardized sets of phenotypic characters and, most recently, to the use of molecular phylogenetic analyses of gene sequences. The present phylogenetic study examines almost all described species (615 taxa) within the family Streptomycetaceae based on 16S rRNA gene sequences and illustrates the species diversity within this family, which is observed to contain 130 statistically supported clades, as well as many unsupported and single member clusters. Many of the observed clades are consistent with earlier morphological and numerical taxonomic studies, but it is apparent that insufficient variation is present in the 16S rRNA gene sequence within the species of this family to permit bootstrap-supported resolution of relationships between many of the individual clusters.

The Ensemble Kalman Filter (EnKF) is coupled with a watershed scale, semi-distributed hydrologic model, the Soil and Water Assessment Tool (SWAT), to assimilate surface (5 cm) soil moisture. By intentionally setting inaccurate precipitation with open loop and EnKF scenarios in a synthetic experiment, the capability of surface soil moisture assimilation to compensate for the precipitation errors were examined. Results show that daily assimilation of surface soil moisture for each HRU improves model predictions especially reducing errors in surface and profile soil moisture estimation. Almost all hydrological processes associated with soil moisture are also improved with decreased root mean square error (RMSE) values through the EnKF scenario. The EnKF does not produce as much a significant improvement in streamflow predictions as compared to soil moisture estimates in the presence of large precipitation errors and the limitations of the infiltration-runoff model mechanism. Distributed errors of the soil water content also show the benefit of surface soil moisture assimilation and the influences of spatially varying inputs such as soil and landuse types. Thus, soil moisture update through data assimilation can be a supplementary way to overcome the errors created by inaccurate rainfall. Even though this synthetic study shows the potential of remotely sensed surface soil moisture measurements for applications of watershed scale water resources management, future studies are necessary that focus on the use of real-time observational data.

In Southeast Alaska, densities were the highest reported for the species, populations were not as closely linked to old-forest attributes, and individuals had a more diverse diet that was less dependent on mycophagy. Pacific Northwest communities are comprised of several arboreal rodents; Southeast Alaska has a depauperate mammal fauna. I hypothesized that Southeast Alaska populations had a broader realized niche because of competitive release. The red squirrel (Tamiasciurus hudsonicus) is the only other arboreal squirrel and it is absent from the southern outer islands of Southeast Alaska's Alexander Archipelago. I compared demography and body mass of G. sabrinus on Prince of Wales Island to a population in sympatry with T. hudsonicus on a separate island (Mitkof). Home ranges were larger and population density, breeding female density, and juvenile recruitment of G. sabrinus were all lower in sympatry with T. hudsonicus. In a companion study, G. sabrinus on Prince of Wales Island used cavities for denning relatively more frequently than in sympatry with T. hudsonicus on Mitkof Island. Female G. sabrinus depend on cavities for natal dens, and breeding female and population densities are positively correlated with large snag or tree density. The presence of T. hudsonicus may influence G. sabrinus populations by limiting availability of cavities. Furthermore, variation in vertebrate assemblages among islands may influence realized niches of resident species, which manifest unique demographic profiles compared to populations of different ecological communities.

DNA sequence variation within and between valleys was compared in a sample of 220 sand flies from three valleys (Purisima, Huaylas, and Conchucos) and five departments (Amazonas, Cajamarca, Piura, Lima, and Huancavelica). Gene network and phylogenetic analyses indicated a high similarity of haplotypes collected within a single valley (0-0.52% nucleotide divergence). Flies from each valley had unique genotypes not shared with specimens from other valleys or from more distant regions (0.8-3.1% nucleotide divergence). Mountain ranges and geographic distance appear to have impeded migration (Nm=<0.18) between valleys and separated populations into discrete genetic units.

A grass that shows appreciable drought tolerance on arid rangelands is Snake River wheatgrass (Elymus wawawaiensis J. Carlson & Barkworth). This study was designed to estimate genetic relationships and underlying genetic components for seed and forage trait improvement between plant introductions (PIs) of Snake River wheatgrass, 28 half-sib Snake River wheatgrass families (HSFs), and cultivars Secar and Discovery at Nephi, Utah, between 2005 and 2006. Based on molecular genetic diversity data in Snake River wheatgrass, with the exception of the PIs originating from Enterprise, Oregon, all other collections and cultivars are not genetically different and represent a common gene pool from which to develop improved Snake River wheatgrass germplasm. Selection in Snake River wheatgrass for total seed yield (g . plot-1), 100-seed weight (g), and seedling emergence from a deep planting depth had a positive effect. Further increases through selection and genetic introgression from hybridization with PIs will likely increase seed yield and 100-seed weight, but will not increase seedling emergence. Increases in dry matter yield (DMY) were observed after two cycles of selection in the HSFs compared to the PIs. There remains considerable genetic and phenotypic variation to further increase DMY in Snake River wheatgrass through selection and hybridization. Trends in forage nutritional quality were not observed after two cycles of selection in the HSFs or the PIs and will not likely result in improvement. Through recurrent selection, populations of Snake River wheatgrass have been and can be developed to more effectively establish and compete on annual weed-infested rangelands.

We investigated potential mechanisms by which crested wheatgrass (Agropyron cristatum L. Gaertn., Agropyron desertorum [[Fisch. {Ex Link} Scult.]]) suppresses the growth and invasibility of cheatgrass. Research focused on monthly mineral soil N availability and the proportional concentration of NH4++-N in a crested wheatgrass community by microsite (crested wheatgrass, unvegetated interspace, shrub subcanopy) and soil depth (0-15, 15-30 cm) over a 1-yr period. Mineral soil N in crested wheatgrass microsites ranged from 0.24 to 1.66 mmol . kg-1 and was not appreciably lower than the other microsites or other ecosystems we have measured in the Great Basin. The molar proportion of NH4++-N in the mineral N pool of crested wheatgrass averaged over 85%% for the year and is significantly higher than the other microsites and far greater than other plant communities we have measured in the Great Basin. We conclude that crested wheatgrass does not suppress cheatgrass by controlling mineral N below a threshold level; rather, we hypothesize that it may limit nitrification and thereby reduce NO3--N availability to the nitrophile cheatgrass.

We inventoried and mapped two such stands on Fort Chaffee Military Training Center in Sebastian County, Arkansas. The west-facing Christmas Knob site is located on an isolated hill, while the southerly-facing Big Creek Narrows site is on a long, narrow rocky outcrop called Devil's Backbone Ridge. These sites occupied rocky, south- to southwest-facing sandstone-dominated slopes, with primarily post oak (Quercus stellata) and blackjack oak (Q. marilandica) overstories. Post oak dominated the largest size classes at both sites. Increment cores indicated that some post oaks exceeded 200 y of age, and tree-ring dating also confirmed an uneven-aged structure to these stands. Both locations had irregular reverse-J shaped diameter distributions, with gaps, deficiencies, and excesses in larger size classes that often typify old-growth stands. On average, the post oaks at the Big Creek Narrows site were taller, larger in girth, and younger than those on the Christmas Knob site, suggestive of a better quality site at Big Creek. The application of neighborhood density functions on stem maps of both sites found random patterns in tree locations.

Using three pairs of pastures stocked at moderate (0.6 animal unit months [[AUM]] . ha-1) versus very heavy (1.2 AUM . ha-1) rates, we detected greater bare soil under very heavy (mean == 22.5%%) versus moderate stocking (mean == 13.5%%; P == 0.053) and a lower coefficient of variation across pastures under very heavy (0.48) versus moderate stocking (0.75; P == 0.032). Bare soil exhibited significant positive spatial autocorrelation across distances of 60-120 m under moderate stocking (Moran's I == 0.14), while patchiness at this scale was eliminated under very heavy grazing (I == -0.05). Across distances of 120-480 m, we observed no spatial autocorrelation with either stocking rate. Spatial autocorrelation was greatest at a separation distance of 2 m (I == 0.48-0.58) but was unaffected by stocking rate at this scale. Thus, very heavy grazing did not increase spatial autocorrelation in bare soil across scales of 2-480 m. Means and variability in the distribution of bare soil were not influenced by ecological site. Bare soil increased primarily at the scale of individual plant clusters through both increases in the density of small (2-20 cm) bare patch intercepts and increases in the frequency of bare patch intercepts of 20-60 cm (rather than < 20 cm). Our approach demonstrates the utility of VLSA for analyzing interactions between grazing and other landscape features and highlights the importance of spatially explicit sampling across broad scales (pastures) while testing for potential shifts in patchiness of bare soil at the scale of plant interspaces.

While pre-emergence herbicides can potentially reduce these two processes, their impact on germination and emergence of downy brome and revegetation species in semiarid ecosystems is poorly understood and has not been comprehensively studied in soils with potentially contrasting herbicide bioavailability (i.e., residual plant activity). We designed a greenhouse experiment to evaluate the effects two pre-emergence acetolactate synthase-inhibiting herbicides (rimsulfuron and imazapic) on germination and emergence of downy brome and two revegetation grass species (crested wheatgrass [[Agropyron cristatum {L.} Gaertn.]] and bottlebrush squirreltail [[Elymus elymoides {Raf.} Swezey]]) that were grown in representative soils from salt desert and sagebrush shrublands. Pre-emergence herbicides significantly (P < 0.05) reduced seedling emergence and biomass production of downy brome and crested wheatgrass and increased mortality more so in sagebrush compared to salt desert soil, suggesting that these common Great Basin soils fundamentally differ in herbicide bioavailability. Also, germination and emergence of the two highly responsive species (crested wheatgrass and downy brome) were clearly more impacted by rimsulfuron than imazapic. We discuss these results in terms of how the specific soil physiochemical properties influence herbicide adsorption and leaching. Our results shed new light on the relative performance of these two promising herbicides and the importance of considering soil properties when applying pre-emergence herbicides to reduce germination and emergence of invasive annual grasses and create suitable seedbed conditions for revegetation.

Temporal relationships between precipitation and aboveground net primary production (ANPP) have been studied extensively in arid and semiarid ecosystems, but rarely has spatial variation in these relationships been investigated at a landscape scale, and rarely has such information been viewed as a resource for mapping the distribution of different ecological states. We examined the broad-scale effects of a shift from grassland to shrubland states on spatiotemporal patterns of remotely sensed ANPP proxies in the northern Chihuahuan Desert. We found that the normalized difference vegetation index (NDVI), when averaged across an eight-year period, did not vary significantly between these states, despite changes in ecosystem attributes likely to influence water availability to plants. In contrast, temporal relationships between precipitation and time-integrated NDVI (NDVI-I) modeled on a per-pixel basis were sensitive to spatial variation in shrub canopy cover, a key attribute differentiating ecological states in the region. The slope of the relationship between annual NDVI-I and 2-year cumulative precipitation was negatively related to, and accounted for 71% of variation in, shrub canopy cover estimated at validation sites using high spatial resolution satellite imagery. These results suggest that remote sensing studies of temporal precipitation-NDVI relationships may be useful for deriving shrub canopy cover estimates in the region, as well as for mapping other ecological state changes characterized by shifts in long-term ANPP, plant functional type dominance, or both.

Males displayed excitatory behaviors when placed in groups, and were attracted to the odors from males that were 2-5-d-old, but not to odors from males that were 0-1-d-old. An unsaturated short-chain alcohol, (Z)-3-decen-1-ol, was discovered in samples collected on SuperQ filters over groups of males and identified by using micro-derivatization reactions and gas chromatography coupled with mass spectrometry (GC-MS). The compound was not detected in volatile samples from females. Gas chromatography coupled electroantennographic detection (GC-EAD) of antennae from males exposed to male headspace odors produced strong antennal responses to the main peak of (Z)-3-decen-1-ol, as well as to an unknown minor component that had a similar retention time. Antennae from both males and females responded to synthetic (Z)-3-decen-1-ol. Several different synthetic candidates for the GC-EAD active minor components were selected based on GC-MS and GC-EAD responses to male headspace collections. These synthetic compounds were tested for antennal activity using GC-EAD, and those that produced strong responses were blended with the major component and tested for male attraction in the Y-tube olfactometer at different concentrations and ratios. Males tested in the Y-tube olfactometer were attracted to a synthetic blend of (Z)-3-decen-1-ol and (Z)-4-decen-1-ol at a ratio of 100:1. Whereas the addition of some suspected minor compounds reduced attraction, the addition of a third compound found in male emanations that produced strong male antennal responses, (E,E)-2,4-decadienal (at a ratio of 100:1:1), resulted in attraction of both males (Y-tube and wind tunnel) and females (wind tunnel).

The chicken is the natural reservoir of C. jejuni where bacteria colonize the digestive tract of poultry, but rarely cause symptoms of disease. To understand the systemic molecular response mechanisms to C. jejuni infection in chickens, total splenic RNA was isolated and applied to a whole genome chicken microarray for comparison between infected (I) and non-infected (N) chickens within and between genetic lines A and B. There were more total splenic host genes responding to the infection in resistant line A than in susceptible line B. Specifically, genes for lymphocyte activation, differentiation and humoral response, and Ig light and heavy chain were upregulated in the resistant line. In the susceptible line, genes for regulation of erythrocyte differentiation, hemopoiesis, and RNA biosynthetic process were all downregulated. An interaction analysis between genetic lines and treatment demonstrated distinct defense mechanisms between lines: the resistant line promoted apoptosis and cytochrome c release from mitochondria, whereas the susceptible line responded with a downregulation of both functions. This was the first time that such systemic defensive mechanisms against C. jejuni infection have been reported. The results of this study revealed novel molecular mechanisms of the systemic host responses to C. jejuni infection in chickens that warrant further investigation.

In this work an optimal controller based on a previously validated SSF model was developed by formulating the SSF process as a Bolza problem and using gradient descent methods. Validation experiments were performed to evaluate the performance of optimal controller under different process disturbances that are likely to occur in practice. Use of optimal control algorithm for the SSF process resulted in lower peak glucose concentration, similar ethanol yields (13.38 plus or minus 0.36% v/v and 13.50 plus or minus 0.15% v/v for optimally controlled and baseline experiments, respectively). Optimal controller improved final ethanol concentrations as compared to process without optimal controller under conditions of temperature (13.35 plus or minus 1.28 and 12.52 plus or minus 1.19% v/v for optimal and no optimal control, respectively) and pH disturbances (12.65 plus or minus 0.74 and 11.86 plus or minus 0.49% v/v for optimal and no optimal control, respectively). Cost savings due to lower enzyme usage and reduced cooling requirement were estimated to be up to $1 million for a 151 million L/yr (40 million gal/yr) dry grind plant.

This has lead to some exaggeration and possible confusion regarding biochar's actual effectiveness as a soil amendment. One sparsely explored area where biochar appears to have real potential for significant impact is the soil nitrogen cycle. Scope: Taghizadeh-Toosi et al. (this issue) examined ammonia sorption on biochar as a means of providing a nitrogen-enriched soil amendment. The longevity of the trapped ammonia was particularly remarkable; it was sequestered in a stable form for at least 12 days under laboratory air flow. Furthermore, the authors observed increased super(15)N uptake by plants grown in soil amended with the super(15)N-enriched biochar, indicating that the super(15)N was not irreversibly bound, but, was plant-available. Conclusions: Their observations add credence to utilizing biochar as a carrier for nitrogen fertilization, while potentially reducing the undesired environmental consequences through gas emissions, overland flow, and leaching.

Aceria solstitialis is an eriophyid mite that has been found exclusively in association with Ce. solstitialis in Italy, Greece, Turkey and Bulgaria. The mite feeds on leaf tissue and damages bolting plants, causing stunting, witch's broom and incomplete flower development. Field experiments and laboratory no-choice and two-way choice experiments were conducted to assess host plant specificity of the mite in Bulgaria. Mites showed the highest degree of host specificity in the field and lowest in the no-choice experiments. In the field, highest densities of mites occurred on Ce. solstitialis and Ce. cyanus (bachelor's button), and either no mites or trace numbers occurred on the other test plants: Ce. diffusa (diffuse knapweed), Carthamus tinctorius (safflower) and Cynara scolymus (artichoke). In no-choice experiments, mites persisted for 60 days on Ce. diffusa, Ce. cyanus, Ce. solstitialis, Ca. tinctorius and Cy. scolymus, whereas in two-way choice experiments mites persisted on 25% of Cy. scolymus plants for 60 days and did not persist on Ca. tinctorius beyond 40 days. The eight other species of plants that were tested in the laboratory were less suitable for the mite. These results suggest that although A. solstitialis can persist on some nontarget plants for as long as 60 days in the laboratory, it appears to be much more specific under natural conditions, and warrants further evaluation as a prospective biological control agent.

Nekton were dominated by exotic species, primarily poeciliids (Gambusia affinis, Poecilia spp.) and tilapia. These fish were present in 50-85% of wetlands sampled; densities were up to 15 times greater than native species. High densities of exotic fish were generally found in isolated wetlands with no connection to the ocean, were often the only nekton present, were positively correlated with surface water total dissolved nitrogen, and were negatively correlated with native species richness. Native species were present in wetlands with complete or partial connection to the ocean. Additional studies are needed to document exotic fish impacts on native fish and bird habitat and whether native fish communities can contribute to invasion resistance of coastal wetlands. Future wetland restoration should include exotic fish eradication, maintenance of hydrological connection to the ocean, or programs to prevent future introductions in order to create wetlands that support native-dominated nekton communities.

UV-C irradiation potentially produces large numbers of random mutations broadly and uniformly over the whole genome to generate unique strains. Wild-type cultures of S. stipitis NRRL Y-7124 were subjected to UV-C (234 nm) irradiation targeted at approximately 40% cell survival. When surviving cells were selected in sufficient numbers via automated plating strategies and cultured anaerobically on xylose medium for 5 months at 28 degree C, five novel mutagenized S. stipitis strains were obtained. Variable number tandem repeat analysis revealed that mutations had occurred in the genome, which may have produced genes that allowed the anaerobic utilization of xylose. The mutagenized strains were capable of growing anaerobically on xylose/glucose substrate with higher ethanol production during 250- to 500-h growth than a Saccharomyces cerevisiae yeast strain that is the standard for industrial fuel ethanol production. The S. stipitis strains resulting from this intense multigene mutagenesis strategy have potential application in industrial fuel ethanol production from lignocellulosic hydrolysates.

In this study, we examined PMA production by 56 strains of the fungus Aureobasidium pullulans representing genetically diverse phylogenetic clades. Thirty-six strains were isolated from various locations in Iceland and Thailand. All strains from Iceland belonged to a newly recognized clade 13, while strains from Thailand were distributed among 8 other clades, including a novel clade 14. Thirty of these isolates, along with 26 previously described strains, were examined for PMA production in medium containing 5% glucose. Most strains produced at least 4 g PMA/L, and several strains in clades 9, 11, and 13 made 9-11 g PMA/L. Strains also produced both pullulan and heavy oil, but PMA isolated by differential precipitation in ethanol exhibited up to 72% purity with no more than 12% contamination by pullulan. The molecular weight of PMA from A. pullulans ranged from 5.1 to 7.9 kDa. Results indicate that certain genetic groups of A. pullulans are promising for the production of PMA.

During the study period (2005-2007), 431 crimes were reported at the 2,813 single-family homes in our sample. In general, the authors find that trees in the public right of way are associated with lower crime rates. The relationship between crime and trees on a house's lot is mixed. Smaller, view-obstructing trees are associated with increased crime, whereas larger trees are associated with reduced crime. The authors speculate that trees may reduce crime by signaling to potential criminals that a house is better cared for and, therefore, subject to more effective authority than a comparable house with fewer trees.

In this study, NO (sub 3) -N, dissolved P (DP) and particulate P (PP) concentrations and loads were investigated for four sub-basins (labeled 1-4 going up the watershed) within a mixed land use watershed (39.5 ha) in the Appalachian Valley and Ridge Physiographic Province. The hot moments of NO (sub 3) -N concentration and load occurred in base flow and during the non-growing season. Great and temporally variable DP and PP concentrations were observed in storm flow. The hot moments of DP concentration and load were in storm flow from May to December and from September to Nov, respectively, while the hot moments of PP concentration and load were in storm flow from January to June. The NO (sub 3) -N, DP, and PP loads were compared for all four sub-basins on a loss per length of stream reach basis to determine the hot spots and their corresponding losses. The hot spots and hot moments of NO (sub 3) -N loads were in Sub-basins 1 and 4 during the non-growing season base flow period and Sub-basin 2 during the post-growing season base flow period (>110 g m (super -1) mo (super -1) ). The hot spots of DP loads were also in Sub-basins 1 and 4, but during the growing and post-growing season storm flow period (>1.4 g m (super -1) mo (super -1) ). In contrast, the hot spots and hot moments of PP load were in Sub-basin 3 during the pre-growing and growing season storm flow, as much as 13.4 and 14.1 g m (super -1) mo (super -1) , respectively. Controlling factors of nutrient export were discussed in this study, including season, hydrology (base flow, storm flow, surface and subsurface runoff), and land use. Although different hot moments and hot spots within the watershed were identified for NO (sub 3) -N, DP, and PP losses, the implementation of a couple of management practices (cover crops and no-till) might be sufficient to effectively reduce nutrient losses from this and similar Valley and Ridge watersheds.

Objectives of this work include (a) to characterize the spatial and temporal patterns of streamflow using information theory-based measures at two thoroughly-monitored agricultural watersheds located in different hydroclimatic zones with similar land use, and (b) to elucidate and quantify temporal and spatial scale effects on those measures. We selected two USDA experimental watersheds to serve as case study examples, including the Little River experimental watershed (LREW) in Tifton, Georgia and the Sleepers River experimental watershed (SREW) in North Danville, Vermont. Both watersheds possess several nested sub-watersheds and more than 30 years of continuous data records of precipitation and streamflow. Information content measures (metric entropy and mean information gain) and complexity measures (effective measure complexity and fluctuation complexity) were computed based on the binary encoding of 5-year streamflow and precipitation time series data. We quantified patterns of streamflow using probabilities of joint or sequential appearances of the binary symbol sequences. Results of our analysis illustrate that information content measures of streamflow time series are much smaller than those for precipitation data, and the streamflow data also exhibit higher complexity, suggesting that the watersheds effectively act as filters of the precipitation information that leads to the observed additional complexity in streamflow measures. Correlation coefficients between the information-theory-based measures and time intervals are close to 0.9, demonstrating the significance of temporal scale effects on streamflow patterns. Moderate spatial scale effects on streamflow patterns are observed with absolute values of correlation coefficients between the measures and sub-watershed area varying from 0.2 to 0.6 in the two watersheds. We conclude that temporal effects must be evaluated and accounted for when the information theory-based methods are used for performance evaluation and comparison of hydrological models.

Currently, there is no vaccine to prevent clinical disease due this parasite in humans, although, various T. gondii vaccine candidates are being developed. Mice are generally used to test the protective efficacy of vaccines because they are susceptible, reagents are available to measure immune parameters in mice, and they are easily managed in the laboratory. In the present study, pathogenesis of toxoplasmosis was studied in mice of different strains, including Human Leukocyte Antigen (HLA) transgenic mice infected with different doses of T. gondii strains of different genotypes derived from several countries. Based on many experiments, the decreasing order of infectivity and pathogenicity of oocysts was: C57BL/6 background interferon gamma gene knock out (KO), HLA-A*1101, HLA-A*0201, HLA-B*0702, Swiss Webster, C57/black, and BALB/c. Mice fed as few as 1 oocyst of Type I and several atypical strains died of acute toxoplasmosis within 21 days p.i. Some Type II, and III strains were less virulent. The model developed herein should prove to be extremely useful for testing vaccines because it is possible to accurately quantitate a challenge inoculum, test the response to different strains of T. gondii using the same preparations of oocysts which are stable for up to a year, and to have highly reproducible responses to the infection.

This study assesses the performance of a new microwave swept frequency domain instrument (SFI) that has promise to provide a low-cost, high-accuracy alternative to the traditional and more expensive time domain reflectometry (TDR). The technique obtains permittivity measurements of soils in the frequency domain utilizing a through transmission configuration, transmissometry, which provides a frequency domain transmissometry measurement (FDT). The measurement is comparable to time domain transmissometry (TDT) with the added advantage of also being able to separately quantify the real and imaginary portiones of the complex permittivity so that the measured bulk permittivity is more accurate that the measurement TDR provides where the apparent permittivity is impacted by the signal loss, which can be significant in heavier soils. The experimental SFI was compared with a high-end 12 GHz TDR/TDT system across a range of soils at varying soil water contents and densities. As propagation delay is the fundamental measurement of interest to the well-established TDR or TDT technique; the first set of tests utilized precision propagation delay lines to test the accuracy of the SFI instrument's ability to resolve propagation delays across the expected range of delays that a soil probe would present when subjected to the expected range of soil types and soil moisture typical to an agronomic cropping system. The results of the precision-delay line testing suggests the instrument is capable of predicting propagation delays with a RMSE of +/-105 ps across the range of delays ranging from 0 to 12,000 ps with a coefficient of determination of r super(2) = 0.998. The second phase of tests noted the rich history of TDR for prediction of soil moisture and leveraged this history by utilizing TDT measured with a high-end Hewlett Packard TDR/TDT instrument to directly benchmark the SFI instrument over a range of soil types, at varying levels of moisture. This testing protocol was developed to provide the best possible comparison between SFI to TDT than would otherwise be possible by using soil moisture as the bench mark, due to variations in soil density between soil water content levels which are known to impact the calibration between TDR's estimate of soil water content from the measured propagation delay which is converted to an apparent permittivity measurement. This experimental decision, to compare propagation delay of TDT to FDT, effectively removes the errors due to variations in packing density from the evaluation and provides a direct comparison between the SFI instrument and the time domain technique of TDT. The tests utilized three soils (a sand, an Acuff loam and an Olton clay-loam) that were packed to varying bulk densities and prepared to provide a range of water contents and electrical conductivities by which to compare the performance of the SFI technology to TDT measurements of propagation delay. For each sample tested, the SFI instrument and the TDT both performed the measurements on the exact same probe, thereby both instruments were measuring the exact same soil/soil-probe response to ensure the most accurate means to compare the SFI instrument to a high-end TDT instrument. Test results provided an estimated instrumental accuracy for the SFI of +/-0.98% of full scale, RMSE basis, for the precision delay lines and +/-1.32% when the SFI was evaluated on loam and clay loam soils, in comparison to TDT as the bench-mark. Results from both experiments provide evidence that the low-cost SFI approach is a viable alternative to conventional TDR/TDT for high accurancy applications.

In this study, the Root Zone Water Quality Model-DSSAT (RZWQM2) was used for simulating plant responses to water stresses in eastern Colorado. Experiments were conducted in 2008, 2009, and 2010 in which maize (Zea Mays L.) was irrigated to meet a certain percentage (100%, 85%, 70%, 55%, and 40%) of the estimated crop evapotranspiration (ETc) demand during a growing season. The model was calibrated with both laboratory-measured and field-estimated soil water retention curves (SWRC) and evaluated for yield, biomass, leaf area index (LAI), and soil water content under five irrigation treatments in all three years. Simulated results showed that field-estimated SWRC provided better model responses to irrigation than laboratory-measured SWRC. The results also showed that there were multiple sets of plant parameters that achieved acceptable simulations when only one irrigation treatment was used for calibration. Model parameterization can be improved when multiple treatments and multiple years of data are included. The parameterized RZWQM2 model was capable of simulating various irrigation treatments in all years and could be used to schedule irrigation based on ETc requirement.

Global soybean production and yield per hectare increased steadily over the past century with improved agronomy and development of cultivars suited to a wide range of latitudes. In order to meet the needs of a growing world population without unsustainable expansion of the land area devoted to this crop, yield must increase at a faster rate than at present. Here, the historical basis for the yield gains realized in the past 90 years are examined together with potential metabolic targets for achieving further improvements in yield potential. These targets include improving photosynthetic efficiency, optimizing delivery and utilization of carbon, more efficient nitrogen fixation and altering flower initiation and abortion. Optimization of investment in photosynthetic enzymes, bypassing photorespiratory metabolism, engineering the electron transport chain and engineering a faster recovery from the photoprotected state are different strategies to improve photosynthesis in soybean. These potential improvements in photosynthetic carbon gain will need to be matched by increased carbon and nitrogen transport to developing soybean pods and seeds in order to maximize the benefit. Better understanding of control of carbon and nitrogen transport along with improved knowledge of the regulation of flower initiation and abortion will be needed to optimize sink capacity in soybean. Although few single targets are likely to deliver a quantum leap in yields, biotechnological advances in molecular breeding techniques that allow for alteration of the soybean genome and transcriptome promise significant yield gains. Soybean is a key component of global food security, providing high-protein animal feed and over half of the world's oilseed production. In this paper, the historical basis for the yield gains realized over the past century and potential metabolic targets for achieving further improvements in yield potential are discussed. These targets include improving photosynthetic efficiency, optimizing delivery and utilization of carbon, more efficient nitrogen fixation and altering flower initiation and abortion.

Such changes in consumer diversity potentially alter community function and impact on resource populations. Although insect herbivore invasions are increasingly common, the influence of such species additions on native resident herbivore guilds, along with their individual and combined effects on native plant resources, are rarely investigated. Here, we used site-to-site and plant-to-plant variation in herbivore composition to examine how the addition of an invasive exotic weevil, Rhinocyllus conicus, combines with a guild of native floral herbivores (tephritid flies, pyralid moths) to influence two key components of herbivore community function - aggregate herbivore densities and cumulative levels of seed destruction - on a native thistle, Cirsium canescens. Invasion of a site by R. conicus more than doubled aggregate herbivore density, resulting in increased levels of seed destruction and a halving of seed production by the native thistle. Further, herbivore function was significantly higher on individual plants attacked by R. conicus, compared to plants attacked only by native herbivores. Insect densities and levels of seed destruction on plants attacked by multiple herbivore taxa never exceeded those observed for plants attacked by R. conicus alone, suggesting that increases in herbivore community function with invasion resulted from the inclusion of a functionally dominant insect rather than any complementarity effects. Some evidence for interference between insects emerged, with a trend towards reduced moth and weevil densities in two and three taxon mixtures compared with plants attacked by each taxon alone. However, density compensation was limited so that, overall, the addition of a novel herbivore to the floral guild was associated with a significant increase in herbivore community function and impact on seed production. The results suggest that invasion of a functionally dominant herbivore into an unsaturated recipient community can augment function within a resource guild.

In the current study, we attempted to confirm powdery mildew resistance phenotypes through vineyard, greenhouse, and in vitro inoculations for test cross-mapping populations for two resistance sources: (i) a complex hybrid breeding line, 'Bloodworm 81-107-11', of at least Vitis rotundifolia, V. vinifera, V. berlandieri, V. rupestris, V. labrusca, and V. aestivalis background; and (ii) Vitis hybrid 'Tamiami' of V. aestivalis and V. vinifera origin. Statistical analysis of vineyard resistance data suggested the segregation of two and three race-specific resistance genes from the two sources, respectively. However, in each population, some resistant progeny were susceptible in greenhouse or in vitro screens, which suggested the presence of Erysiphe necator isolates virulent on progeny segregating for one or more resistance genes. Controlled inoculation of resistant and susceptible progeny with a diverse set of E. necator isolates clearly demonstrated the presence of fungal races differentially interacting with race-specific resistance genes, providing proof of race specificity in the grape powdery mildew pathosystem. Consistent with known race-specific resistance mechanisms, both resistance sources were characterized by programmed cell death of host epidermal cells under appressoria, which arrested or slowed hyphal growth; this response was also accompanied by collapse of conidia, germ tubes, appressoria, and secondary hyphae. The observation of prevalent isolates virulent on progeny with multiple race-specific resistance genes before resistance gene deployment has implications for grape breeding strategies. We suggest that grape breeders should characterize the mechanisms of resistance and pyramid multiple resistance genes with different mechanisms for improved durability.

To date, five necrotrophic effector-host gene interactions have been identified in this system. Most of these interactions have additive effects while some are epistatic. The Snn4-SnTox4 interaction was originally identified in a recombinant-inbred population derived from a cross between the Swiss winter wheat cultivars 'Arina' and 'Forno' using the S. nodorum isolate Sn99CH 1A7a. Here, we used a recombinant-inbred population consisting of 121 lines developed from a cross between the hexaploid land race Salamouni and the hexaploid wheat 'Katepwa' (SK population). The SK population was used for the construction of linkage maps and quantitative trait loci (QTL) detection using the Swiss S. nodorum isolate Sn99CH 1A7a. The linkage maps developed in the SK population spanned 3,228 centimorgans (cM) and consisted of 441 simple-sequence repeats, 9 restriction fragment length polymorphisms, 29 expressed sequence tag sequence-tagged site markers, and 5 phenotypic markers. The average marker density was 6.7 cM/marker. Two QTL, designated QSnb.fcu-1A and QSnb.fcu-7A on chromosome arms 1AS and 7AS, respectively, were associated with disease caused by the S. nodorum isolate Sn99CH 1A7a. The effects of QSnb.fcu-1A were determined by the Snn4-SnTox4 interaction and accounted for 23.5% of the phenotypic variation in this population, whereas QSnb.fcu-7A accounted for 16.4% of the phenotypic variation for disease but was not associated with any known effector sensitivity locus. The effects of both QTL were largely additive and collectively accounted for 35.7% of the total phenotypic variation. The results of this research validate the effects of a compatible Snn4-SnToxA interaction in a different genetic background, and it provides knowledge regarding genomic regions and molecular markers that can be used to improve Stagonospora nodorum blotch resistance in wheat germplasm.

PemK toxin inhibits bacterial growth; PemI is the corresponding antitoxin that blocks activity of PemK by direct binding. PemK and PemI were overexpressed in Escherichia coli and activities of each were assessed. Purified PemK toxin specifically degraded single-stranded RNA but not double-stranded RNA, double-stranded DNA, or single-stranded DNA. Addition of PemI antitoxin inhibited nuclease activity of PemK toxin. Purified complexes of Peml bound to PemK exhibited minimal nuclease activity; removal of PemI antitoxin from the complex restored nuclease activity of PemK toxin. Sequencing of 5' rapid amplification of cDNA ends products of RNA targets digested with PemK revealed a preference for cleavage between U and A residues of the sequence UACU and UACG. Nine single amino-acid substitution mutants of PemK toxin were constructed and evaluated for growth inhibition, ribonuclease activity, and PemI binding. Three PemK point-substitution mutants (R3A, G16E, and D79V) that lacked nuclease activity did not inhibit growth. All nine PemK mutants retained the ability to bind PemI. Collectively, the results indicate that the mechanism of stable inheritance conferred by pXF-RIV11 pemI/pemK is similar to that of the R100 pemI/pemK TA system of E. coli.

While the storm water runoff and surface loading of nutrients into many rivers have been explored in great detailed, the groundwater discharge of nutrients into the rivers has not yet been thoroughly quantified. This study ascertained the shallow groundwater discharges and nutrient loads into the Lower St. Johns River (LSJR), FL, USA. The groundwater discharges were obtained using Darcy's law along with field measured hydrological parameters, whereas the groundwater nutrient loads were calculated based on the groundwater discharges and the field measured nutrient concentrations. The average rate of groundwater discharge per unit cross-section area over the four selected sites along the LSJR was about 1.210-2m3m-2d-1. The average loads of groundwater nutrients into the adjacent LSJR were 10.6 and 5.6mgm-2d-1, respectively, for nitrate- and nitrite-nitrogen (NOx-N) and total phosphorus (TP). In general, seasonal variations of the groundwater levels were larger than the river stages, whereas site variations of groundwater nutrient concentrations were larger than seasonal variations of groundwater nutrient concentrations. Results from this study are useful for estimation of groundwater contamination and river eutrophication.

A good understanding of biofuel policy's impact on price variability is important for mitigating food insecurity and assisting policy formation. We examine how U.S. ethanol policies such as the Renewable Fuel Standard (RFS) mandates and the blend wall affect the price variability of corn and gasoline. We first present an analytical and graphical framework to identify the effect and then use stochastic partial equilibrium simulation to measure the magnitude of the impacts. We show that RFS mandates and the blend wall both reduce the price elasticity of demand for corn and gasoline and therefore increase the price variability when supply shocks occur to the markets. This has important implications for policy actions with respect to maintaining or changing the current RFS mandates and/or blend wall in the US.

Here the isolation, expression and function of tra and tra-2 orthologs are described for the agriculturally important tephritid, Anastrepha suspensa, and their possible use in genetically modified organisms for biologically-based pest management. The Astra and Astra-2 genes are highly conserved in structure, regulation and function with respect to those known from other tephritid species. Sex-specific transcripts for Astra were detected, one in females and three in males, whereas Astra-2 had a single common transcript found in both sexes. To test the function of these genes, Astra and Astra-2 dsRNA was injected into A. suspensa embryos from a transgenic strain having a Y-linked DsRed marker integration, allowing XY males to be distinguished from XX phenotypic males. Nearly all XX embryos developed into fully masculinized phenotypic male adults with no apparent female morphology. Upon dissection abnormal hypertrophic gonads were revealed in XX pseudomales but not in the XY males. Our findings suggest that Astra and Astra-2 are both necessary for female development, and that the potential exists for producing a male-only population when either gene alone, or both genes simultaneously, are knocked-down.

AN - 912918174; 21983260 AB - One strategy to enhance the durability of Hessian fly resistance (R) genes in wheat is to combine them with transgenes for resistance. To identify potential transgenes for resistance a protocol for rapidly screening the proteins they encode for efficacy toward resistance is required. However, the Hessian fly is an obligate parasite of wheat and related grasses. Consequently, no protocol for in vitro delivery of antinutrient or toxic proteins to feeding larvae is available. We report here the development of a Hessian fly in plantatranslocation (HIT) feeding assay and the evaluation of eight lectins and the Bowman-Birk serine proteinase inhibitor for potential in transgenic resistance. Of the antinutrient proteins evaluated, Galanthus nivalis L. agglutinin (GNA), commonly termed snowdrop lectin, was the most efficacious. Ingestion of GNA caused a significant reduction in growth of Hessian fly larvae, disruption of midgut microvilli, and changes in transcript level of genes involved in carbohydrate metabolism, digestion, detoxification, and stress response. These effects of GNA are discussed from the perspective of larval Hessian fly physiology. Published by Elsevier Ltd.

AN - 912638678; 21770011 AB - The longevity, mobility and insecticidal activity of bifenthrin at the termiticidal application rate for perimeter treatment were investigated in packed-soil columns in the laboratory and greenhouse. Bifenthrin was not detected in the eluates of packed-soil cones over a period of 6 months. In larger pipe plots incorporating bifenthrin into the top 15 cm of the soil, the compound degraded in a biphasic fashion. Within the treated soil, the effect of vegetation on the amount of bifenthrin remaining in the soil depended on soil depth and time, and soil half-lives were longer in non-vegetated soil. Bifenthrin residues were higher in the top 7.5 cm of soil and declined over time. Movement of bifenthrin into the top untreated soil depth was observed, but much less was observed in lower depths. The soil remained toxic to termites in 3 day and 7 day forced exposure bioassays for the 30 month duration of the study. Concentrations of bifenthrin will remain in the soil at levels sufficient to kill termites for more than 30 months. This article is a US Government work and is in the public domain in the USA.

AN - 911934781; 21665318 AB - Many epidemiological studies show the benefit of fruits and vegetables on reducing risk of lung cancer, the leading cause of cancer death in the United States. Previously, we demonstrated that cigarette smoke exposure (SM)-induced lung lesions in ferrets were prevented by a combination of low dose of β-carotene, α-tocopherol (AT), and ascorbic acid (AA). However, the role of a combination of AT and AA alone in the protective effect on lung carcinogenesis remains to be examined. In the present study, we investigated whether the combined AT (equivalent to ∼100 mg/day in the human) and AA (equivalent to ∼210 mg/day) supplementation prevents against SM (equivalent to 1.5 packs of cigarettes/day) induced lung squamous metaplasia in ferrets. Ferrets were treated for 6 weeks in the following three groups (9 ferrets/group): (i) Control (no SM, no AT+AA), (ii) SM alone, and (iii) SM+AT+AA. Results showed that SM significantly decreased concentrations of retinoic acid, AT, and reduced form of AA, not total AA, retinol and retinyl palmitate, in the lungs of ferrets. Combined AT+AA treatment partially restored the lowered concentrations of AT, reduced AA and retinoic acid in the lungs of SM-exposed ferrets to the levels in the control group. Furthermore, the combined AT+AA supplementation prevented SM-induced squamous metaplasia [0 positive/9 total ferrets (0%) vs. 5/8 (62%); p<0.05] and cyclin D1 expression (p<0.05) in the ferret lungs, in which both were positively correlated with expression of c-Jun expression. Although there were no significant differences in lung microsomal malondialdehyde (MDA) levels among the three groups, we found a positive correlation between MDA levels and cyclin D1, as well as c-Jun expressions in the lungs of ferrets. These data indicate that the combination of antioxidant AT+AA alone exerts protective effects against SM-induced lung lesions through inhibiting cyclin D1 expression and partially restoring retinoic acid levels to normal.

We measured fecal indicator bacteria (commensal Escherichia coli and fecal enterococci) and manure pathogens (Salmonella and E. coli 0157:H7), and physical-chemical parameters in pond inflow, within pond, pond outflow, and pond sediments in three ponds in agricultural watersheds. Bishop Pond with perennial inflow and outflow is located in the Piedmont, and Ponds A and C with ephemeral inflow and outflow in the Coastal Plain of Georgia. Bromide and chloride tracer experiments at Bishop Pond reflected a residence time much greater than that estimated by two models, and indicated that complete mixing within Bishop Pond was never obtained. The long residence time meant that fecal bacteria were exposed to solar UV-radiation and microbial predation. At Bishop Pond outflow concentrations of fecal indicator bacteria were significantly less than inflow concentrations; such was not observed at Ponds A and C. Both Salmonella and E. coli 0157:H7 were measured when concomitant concentrations of commensal E. coli were below the criterion for surface water impairment indicating problems with the effectiveness of indicator organisms. Bishop Pond improved down stream water quality; whereas, Ponds A and C with ephemeral inflow and outflow and possibly greater nutrient concentrations within the two ponds appeared to be less effective in improving down stream water quality.

In 2007, we estimated the survival of 2210 recently germinated seedlings of nine tree species transplanted near conspecific and heterospecific trees, a surrogate for describing distance-dependent mortality, as part of an experiment with landscape-level replication across eight mixed-deciduous forests in the southern Appalachian Mountains of North Carolina. Forest composition was variable but they had a number of woody species in common. Prior to establishing the field experiment, we used a forest inventory database for the region to classify the recruitment patterns of tree species and formulate predictions for species. The field experiment, conducted as a drought was progressing, revealed that four of the nine species planted had variable survival around conspecifics compared with heterospecifics suggesting variation in distance-dependent mortality. Acer saccharum and Tsuga canadensis both had greater mortality near conspecifics than heterospecifics, while Fagus grandifolia and Prunus serotina showed the opposite pattern. Species classified as having greater recruitment around conspecifics, according to the forest inventory data, suffered greater overall levels of mortality in our field experiment. Possibly because of the progressing drought, none of the four species predicted to be most affected by distance-dependent sources of mortality based on the forest inventory data exhibited the predicted patterns of survival near conspecific vs. heterospecific trees in the field experiment. Furthermore, two of the four species (A. saccharum and T. canadensis) classified as being least affected by conspecific trees actually had greater survival near heterospecifics than conspecifics. Although we identified effects of canopy tree type in four of the nine comparisons, negative effects of conspecific trees were observed for only two (A. saccharum and T. canadensis) of nine species and mostly contradicted predictions based on patterns from forest inventory data. The inconsistency between patterns from the forest inventory data and from experiments indicates that there may be localized, complex interactions that make generalizations about neighbor effects on tree seedling survival difficult.

There are at least 12 species of hymenopteran parasitoids attacking eggs of Agrilus beetles and 56 species (36 genera), attacking Agrilus larvae infesting various host plants in North America, Asia, and Europe. While most of the egg parasitoids (9 species) belong to the family Encyrtidae, a majority of the larval parasitoids are members of five families: Braconidae (24 species/11 genera), Eulophidae (8 species/4 genera), Ichneumonidae (10 species/9 genera), and Eupelmidae (6 species/5 genera). The highest rate of Agrilus egg parasitism (>50%) was exerted by encyrtid wasps (4 species) in North America, Asia, and Europe. In contrast, the highest rate of Agrilus larval parasitism (>50%) was caused by species in two genera of braconids: Atanycolus (North America) and Spathius (Asia), and one eulophid genus, Tetrastichus (Asia and Europe). Reported rate of Agrilus larval parasitism ichneumonids was frequent in North America, but generally low (<1%). Potential for success in biological control of emerald ash borer (Agrilus planipennis Fairmaire) in the USA with North American native parasitoids and old-association Asian parasitoids is discussed.

The Bushland Reference ET Calculator was developed by the USDA-ARS Conservation and Production Research Laboratory at Bushland, Texas for calculating hourly and daily grass and alfalfa reference ET. The user-friendly interface for the calculator was developed using .NET programming. The calculator uses the ASCE Standardized Reference Evapotranspiration (ET) Equation for calculating both grass and alfalfa reference ET at hourly and daily time steps. Users have the option of using a single set or time series weather data to calculate reference ET. Daily reference ET can be calculated either by summing the hourly ET values for a given day or by using daily averages of the climatic data. Although the Bushland Reference ET Calculator was designed and developed for use mainly by producers and crop consultants to manage irrigation scheduling, it can also be used in educational training, research, and other practical applications. This paper demonstrates use of the Bushland Reference ET Calculator that is available from the USDA-ARS Conservation and Production Research Laboratory web site to interested users at no cost.

An annual, watershed-scale water budget analysis was conducted to identify alternative water conservation and water use scenarios, and to determine their effectiveness at reducing groundwater extraction. The scenario analysis showed that even with a 10% reduction in industrial and urban water use and a 50% reduction in irrigation water the annual groundwater deficit remains above 10 [106 m3/yr]. The political and socioeconomic impacts of such large reductions in water use are likely to be unacceptable. At best, a freezing of industrial and urban water use at the level of year 2010 and a 50% reduction in irrigation water use can be hoped for, which leads to an annual groundwater deficit of about 20 [106 m3/yr]. This is a great improvement over the 75 [106 m3/yr] groundwater deficit of year 2010, and could potentially be adopted as a target deficit that qualifies as sustainable utilization of groundwater resources. To achieve a 50% reduction in irrigation water use will likely involve a combination of higher irrigation efficiencies, introduction of low water-demand crops, reduction in number of existing irrigation wells, land conversions, deficit irrigation, and irrigation regulations. However, circumstantial evidence suggested that the annual irrigation water reported in the literature and used in the water budget analysis was a low estimate while groundwater recharge from rainfall was a high estimate. Thus, projected annual groundwater deficits are potentially larger than reported in this study.

The software can be used to conduct simulations, carry out design and operational analyses, and evaluate performance from field-measured data. Version 3.1 was released in 2009 and a new version, V. 4.1 is scheduled for 2012. This release provides a limited number of analytical enhancements for the end user, but it represents a major software upgrade. The simulation engine, known as SRFR, has been entirely rewritten using modern object-oriented programming concepts. This recoding effort was undertaken to facilitate the continued development of the SRFR code and to provide the application with a well-defined application programming interface. The paper discusses the architecture of the new SRFR engine and the resulting enhancements to the WinSRFR program.

RUSLE2 is supported by extensive databases maintained by the USDA-Natural Resources Conservation Service. It is commonly accessed through a graphical user interface (GUI) running in a Windows environment, but is also a dynamic-link library (DLL) version that uses the same scientific code and can interact with other computer programs through an application programming interface (API). In addition to average annual erosion and sediment delivery, recent enhancements give RUSLE2 the ability to predict a representative runoff event sequence for a particular location, soil, management, and user-specified return period that can be coupled with a channel erosion and routing model. These features make RUSLE2 applicable to TMDL modeling.

In this study, the submicromolar concentrations of methylselenol were generated by incubating methionase with seleno-L methionine, and colon-cancer-derived HCT-116 cells and noncancerous colon NCM460 cells were exposed to methylselenol. Methylselenol exposure inhibited cell growth and led to an increase in G1 and G2 fractions with a concomitant drop in S-phase and an induction of apoptosis in HCT116, but to a much lesser extent in NCM460 colon cells. Similarly, the examination of mitogen-activated protein kinase (MAPK) and cellular myelocytomatosis oncogene (c-Myc) signaling status revealed that methylselenol inhibited the phosphorylation of extracellular-regulated kinase1/2 and p38 mitogen-activated protein kinase and the expression of c-Myc in HCT116 cells, but also to a lesser extent in NCM460 cells. The other finding is that methylselenol inhibits sarcoma kinase phosphorylation in HCT116 cells. In contrast, methylselenol upregulated the phosphorylation of sarcoma and focal adhesion kinase survival signals in the noncancerous NCM460 cells. Collectively, methylselenol's stronger potential of inhibiting cell proliferation/survival signals in the cancerous HCT116 cells when compared with that in noncancerous NCM460 cells may partly explain the potential of methylselenol's anticancer action.

Luminescence measurements based on quantitation of the ATP present were used to determine the amount of biofilm elimination and correlated with quantity of live bacteria present in the sample. The data were analyzed employing a two-way ANOVA and Bonferroni post-test. Treatments resulted in percentage reductions of E. coli biofilms ranging from 73 to 98%. Lactoferrin (40 mu g/ml) produced a significantly higher-percentage reduction than lysozyme (10 mu g/ml) (P < 0.05), no other significant differences occurred. Similar treatments resulted in percentage reductions of K. pneumoniae subsp. pneumoniae biofilms ranging from 51 to 100%. Dextranase treatments produced a significantly lower percentage reduction than all other materials (P < 0.05), no other significant differences occurred. No material was capable of complete destruction of both single species biofilms; however, low concentrations of lactoferrin and lysozyme each removed 100 % of the K. pneumoniae subsp. pneumoniae biofilm. Low concentrations of lactoferrin or lysozyme might be beneficial to prevent biofilm formation by K. pneumoniae subsp. pneumoniae.

Moreover, these measurements can help to include the effect of shallow groundwater on surface energy balance within land surface models and climate studies, which broadens the methods that yield more reliable and informative results. To examine the capacity of MODIS in detecting the effect of shallow groundwater on land surface temperature and the surface energy balance in an area within Al-Balikh River basin in northern Syria, we studied the interrelationship between in-situ measured water table depths and land surface temperatures measured by MODIS. We, also, used the Surface Energy Balance System (SEBS) to calculate surface energy fluxes, evaporative fraction and daily evaporation, and inspected their relationships with water table depths. We found out that the daytime temperature increased while the nighttime temperature decreased when the depth of the water table increased. And, when the water table depth increased, net radiation, latent and ground heat fluxes, evaporative fraction and daily evaporation decreased, while sensible heat flux increased. This concords with the findings of a companion paper (Alkhaier et al., 2012). The observed clear relationships were the result of meeting both conditions that were concluded in the companion paper, i.e. high potential evaporation and big contrast in day-night temperature. Moreover, the prevailing conditions in this study area helped SEBS to yield accurate estimates. Under bare soil conditions and under the prevailing weather conditions, we conclude that MODIS is suitable for detecting the effect of shallow groundwater because it has proper imaging times and adequate sensor accuracy; nevertheless, its coarse spatial resolution is disadvantageous.

To investigate the shallow groundwater effect under bare soil conditions, we numerically exposed two soil profiles to identical metrological forcing. One of the profiles had shallow groundwater. The different responses that the two profiles manifested were inspected regarding soil moisture, temperature and energy balance at the land surface. The findings showed that the two profiles differed in three aspects: the absorbed and emitted amounts of energy, the portioning out of the available energy and the heat fluency in the soil. We concluded that due to their lower albedo, shallow groundwater areas reflect less shortwave radiation and consequently get a higher magnitude of net radiation. When potential evaporation demand is sufficiently high, a large portion of the energy received by these areas is consumed for evaporation. This increases the latent heat flux and reduces the energy that could have heated the soil. Consequently, lower magnitudes of both sensible and ground heat fluxes are caused to occur. The higher soil thermal conductivity in shallow groundwater areas facilitates heat transfer between the top soil and the subsurface, i.e. soil subsurface is more thermally connected to the atmosphere. For the reliability of remote sensors in detecting shallow groundwater effect, it was concluded that this effect can be sufficiently clear to be detected if at least one of the following conditions occurs: high potential evaporation and high contrast between day and night temperatures. Under these conditions, most day and night hours are suitable for shallow groundwater depth detection.

We sampled 300 plants on a north- and on a south-facing slope, determined age structure, and compared results to those of other studies in topographically flat areas using regression and ANOVA. We found that growth rates are about the same for the two slopes, but more young Carnegiea were documented on the south-facing than on the north-facing slope, likely due to microclimatic differences and susceptibilities. Fewer individuals were represented in the higher age classes than often found in topographically flat populations. We found that individuals are faster growing on slopes than on flats, likely due to differences in sediment size and make-up. Finally, a recent study linked worldwide volcanism with cohort establishment in topographically flat areas. We found that successful cohort establishment in both populations (north- and south-facing) was significantly higher during years with greater volcanic activity (and the years that were subsequently influenced by airborne materials ejected from the eruption), the first such observation for sloped populations. Volcanic eruptions occurring worldwide impact the regeneration success of this species, and in a variety of topographic settings, extending our previous knowledge of the link between global geologic events and climate change with the regeneration of this species locally (the first ever documented), which with further research will surely be extended to other species in other biomes worldwide.

Much of the debate has centered on the carbon storage implications of utilizing whole trees for energy and the time frame necessary to offset the carbon emissions associated with fixed-life bioenergy facilities. Forest harvest residues may provide a cost-effective, carbon friendly alternative; however, robust empirical estimates of the carbon consequences of utilizing this feedstock are needed to inform policy and management related to forest-based bioenergy. This study used a modeling approach to assess the availability of harvest residues in northern Minnesota and compared the estimated carbon emissions from in-forest decomposition with emissions from processing, transport, and utilization of residues in a proposed 26 MW bioenergy facility. Model results suggest that the combined emissions from the proposed facility would be 42 percent greater - a net difference of 2,888,751 Mg of CO[sub]2 - than in-forest decomposition emissions over a 25-year period. The disparity in carbon emissions with and without the proposed facility decreases with increasing time, ultimately reducing to solely emissions from harvesting and transport 190+ years after establishment. These findings have important implications for the development of renewable energy standards including incentives aimed at increasing the use of forest-derived biomass.

In addition, this yeast is tolerant to the major inhibitors derived from lignocellulosic biomass pre-treatment such as 2-furaldehyde (furfural) and 5-(hydroxymethyl)-2-furaldehyde (HMF), and converted furfural into furan methanol in less than 12 h and HMF into furan-2,5-dimethanol within 24 h in the presence of 15 mM each of furfural and HMF. Using xylose-extracted corncob residue as cellulosic feedstock, an ethanol production of 23 g/l was obtained using 25% solids loading at 37 degree C by SSF without addition of exogenous beta -glucosidase. Development of this yeast aids renewable biofuels development efforts for economic consolidated SSF bio-processing.

The algorithms utilized the fluorescence intensities at four wavebands, 680, 684, 720, and 780 nm, for computation of simple functions for effective detection of contamination spots created on the apple surfaces using four concentrations of aqueous fecal dilutions. The algorithms detected more than 99% of the fecal spots. The effective detection of feces showed that a simple multispectral fluorescence imaging algorithm based on violet LED excitation may be appropriate to detect fecal contamination on high-speed apple processing lines. This fast and non-destructive method for detection of fecal contamination can be implemented in the food and agricultural industries to help in risk reduction and food safety assurance for preventing or minimizing the potential foodborne illness.

The E. coli O157:H12 survived in two sediments with markedly different particle size distributions and organic matter contents in one-month-long experiments in flow-through chambers at 14 degree C and 23 degree C. The inactivation rates after re-inoculation were smaller than after inoculation; the differences were significant (P < 0.1) in two of four experiments. This study suggests that E. coli O157:H12 was able to adapt to the sediment environment so that its survival after re-inoculation improved.

(cheatgrass) is an Eurasian annual grass that has invaded ecosystems throughout the Intermountain west of the United States. Our purpose was to examine mechanisms by which established perennial grasses suppress the growth of B. tectorum . Using rhizotrons, the experiment was conducted over 5 growth cycles: (1) B. tectorum planted between perennial grasses; (2) perennials clipped and B. tectorum planted; (3) perennials clipped and B. tectorum planted into soil mixed with activated carbon; (4) perennials clipped, B. tectorum planted, and top-dressed with fertilizer, and; (5) perennial grasses killed and B. tectorum planted. Water was not limiting in this study. Response variables measured at the end of each growth cycle included above-ground mass and tissue nutrient concentrations. Relative to controls (B. tectorum without competition), established perennial grasses significantly hindered the growth of B. tectorum . Overall, biomass of B. tectorum , grown between established perennials, increased considerably after fertilizer addition and dramatically upon death of the perennials. Potential mechanisms involved in the suppression of B. tectorum include reduced nitrogen (possibly phosphorus) availability and coopting of biological soil space by perennial roots. Our data cannot confirm or reject allelopathic suppression. Understanding the mechanisms involved with suppression may lead to novel control strategies against B. tectorum .

PLANTS AN - 1458527075; 17938127 AB - The response of hydroponically cultivated rapeseed (Brassica napus L.; c.v. Verona) plants to Cd, Ni (6-120 mu mol L super(-1)) and Hg (6-60 mu mol L super(-1)) was investigated. Metal application resulted in reduced length as well as dry mass of rapeseed plant organs and the inhibitory effect increased with increasing metal concentration in external solution. Due to metal application significant decrease in the concentration of assimilation pigments (chlorophyll a, chlorophyll b, carotenoids) and proteins in rapeseed leaves was observed. At the highest applied concentration leaf protein content represented only 47.3% (Cd), 60.9% (Ni) and 56.4% (Hg) of the control. On the other hand, concentration of thiobarbituric acid reactive substances (TBARS) rose with the increasing metal concentration. Due to treatment with 120 mu mol L super(-1) Cd or Ni, TBARS content was 1.64 (Cd) and 2.28 (Ni) times higher than that of the control, while after application of 60 mu mol L super(-1) Hg it was about 2.91 times higher. Metal treatment was also connected with loss of water content in shoot, which was the smallest at Ni application. Treatment with 120 mu mol L super(-1) Ni resulted in 12.7% loss of water in comparison to control plants while at application of the same Cd concentration loss of water reached 37%. In general, the highest toxicity was exhibited by Hg. Accumulated metal concentrations in roots of rapeseed cultivar Verona showed linear increase with increasing external Cd, Ni and Hg concentration. The lowest metal concentration in shoot tissue exhibited Hg. The effectiveness of metal translocation from root to shoot increased as follows: Hg < Cd CSH > CSHAA > CS > CC. Nitrogen-use efficiency was greatest under CSW and least under CC. There were no differences in yield advantage (YA) among crop rotations during years with plentiful early-season rainfall (May 1-July 31). In years with low spring rainfall, YA was greatest under CSW (54%) and least under CSHAA (33%). Corn yields under extended rotations (CSH, CSW, and CSHAA) were greater than under CC and CS, but lack of rainfall may result in reduced yields under CSHAA.

One question that arises about the potential effects of introducing a nonnative species is what effect will there be on fire behavior. Our approximate answer based on modeling fire behavior using the Fuel Characteristic Classification System is that surface fire behavior in young stands differs little from surface fires common to pine plantations in the southern Coastal Plain. By the age of 9, the absence of a shrub layer, along with an increased height to live crown, reduced initiation potential despite increased bark shedding. When a shrub layer was introduced in the model, the initiation potential became equivalent to common Pinus fuelbeds. If a crown is ignited, however, the potentials for transmissivity and spread are very high, and the potential for crown fire behavior is more severe. Our modeling effort suggests that fire behavior at the stand level differs little from current conditions and points to the importance of avoiding the development of a shrub layer. Stands managed on short rotation (less than 10 years) will likely be harvested before bark shedding presents a significant spotting problem.

The analysis is based on economic and biophysical models that we've designed to evaluate public water quality conservation strategies. Results indicate that increasing the use of onfield nitrogen conservation practices, targeted to lands in corn-corn rotation (with a nitrogen-removal cost of $0.17 per pound), is the most cost-effective nitrogen conservation strategy. But the cost of further reductions in nitrogen losses by offering incentives to farmers with a corn-soybean rotation rises to $0.62 per pound. The authors found that wetland restoration is the second most cost-effective strategy. The average nitrogen removal cost of five- to ten-acre wetlands ranges from $0.23 to $0.24 per pound - when the wetlands are located to receive aquatic nitrogen flows. Nitrogen removal by VFS, in a best-case scenario, costs $0.41 per pound, but could be much higher. The analysis and results are based on conditions within a single Ohio county, two crop rotations, and a limited number of wetland options. However, the approach used here can be applied to assess different mixes of conservation practices and to determine which conservation practices are most cost-effective.

Pedometers are simple, convenient, and economical tools that can be used to quantify step-determined physical activity. Few studies have attempted to define the direct relationship between dynamic changes in pedometer-determined steps/day and changes in anthropometric and clinical outcomes. Hence, the objective of this secondary analysis was to evaluate the utility of several descriptive indicators of pedometer-determined steps/day for predicting changes in anthropometric and clinical outcomes using data from a community-based walking intervention, HUB City Steps, conducted in a southern, African American population. A secondary aim was to evaluate whether treating steps/day data for implausible values affected the ability of these data to predict intervention-induced changes in clinical and anthropometric outcomes. Methods: The data used in this secondary analysis were collected in 2010 from 269 participants in a six-month walking intervention targeting a reduction in blood pressure. Throughout the intervention, participants submitted weekly steps/day diaries based on pedometer self-monitoring. Changes (six-month minus baseline) in anthropometric (body mass index, waist circumference, percent body fat [%BF], fat mass) and clinical (blood pressure, lipids, glucose) outcomes were evaluated. Associations between steps/day indicators and changes in anthropometric and clinical outcomes were assessed using bivariate tests and multivariable linear regression analysis which controlled for demographic and baseline covariates. Results: Significant negative bivariate associations were observed between steps/day indicators and the majority of anthropometric and clinical outcome changes (r = -0.3 to -0.2: P < 0.05). After controlling for covariates in the regression analysis, only the relationships between steps/day indicators and changes in anthropometric (not clinical) outcomes remained significant. For example, a 1,000 steps/day increase in intervention mean steps/day resulted in a 0.1% decrease in %BF. Results for the three pedometer datasets (full, truncated, and excluded) were similar and yielded few meaningful differences in interpretation of the findings. Conclusions: Several descriptive indicators of steps/day may be useful for predicting anthropometric outcome changes. Further, manipulating steps/day data to address implausible values has little overall effect on the ability to predict these anthropometric changes.

To ensure that operations are managed sustainably across environmental, socio-cultural, and economic dimensions, operating standards are implemented through ecotourism certification programmes. This study examined international ecotourism operators' internet promotion of educational offerings, viewed as interpretive products, and interpretive sustainability practices. The primary focus was to understand differences in internet promotion of educational offerings between certified and non-certified operators. Stratified systematic sampling techniques rendered sampling of 29.9% (227/759) of the population. Data were analysed using domain analysis and logistic regression. The results revealed that certified and non-certified operators promote and practice education in the delivery of their ecotourism services; however, divergences existed between certified and non-certified operators with non-certified operators portraying clearer messages of education in their internet promotion. These findings led to question of why differences exist between these groups' internet promotion of education as well as what are the merits of ecotourism certification agencies' requirements for marketing standards of education. Understanding the role of education in certification marketing is critical to ensuring sustainability of ecotourism operators as well as in establishing a shared philosophy between operators, visitors, and residents.

Diagnosis of BoNT often relies on the mouse bioassay that has a detection limit of 10-20 pg-mL and can take up to four days to complete. Rapid in vitro methods for toxin detection are needed and to date, most rely on either immunoassay or endopeptidase activity. In the latter, many also use specific antibodies to concentrate the toxin. We have developed panels of monoclonal antibodies (mAbs) to purified toxin, serotypes A, B and E, as well as mAbs to the non-toxic associated proteins. Application of these mAbs in sandwich ELISAs and assay performance in milk and other foods is discussed. The assays described here are able to detect toxin in a few hours, at levels lower than the mouse bioassay.

We monitored larval populations of a recently introduced weed biocontrol agent, Neomusotima conspurcatalis Warren, at field sites in Florida to investigate parasitism by native parasitoids and to assess the overall rate of parasitism. Of six native parasitoid species reared from wild larvae of N. conspurcatalis, five, Rhygoplitis choreuti (Viereck), Stantonia pallida (Ashmead), Elasmus apanteli Gahan, Hyphantrophaga sellersi (Sabrosky), and an unidentified Cotesia sp. were primary parasitoids of the biocontrol agent. The sixth species, Mesochorus apantelis Dasch, is likely a hyperparasitoid of R. choreuti. From 1,100 N. conspurcatalis larvae collected from three sites, adult parasitoids emerged from 6.8% of those larvae and 73.6% of the N. conspurcatalis developed to adulthood. R. choreuti was the most common parasitoid, accounting for 81% of adults reared. Photographs of parasitoid species are provided, aspects of their natural histories and host ranges are described, and accumulation of native parasitoids on introduced weed biocontrol agents is discussed.

Because they have extirpated the native forest avifauna on Guam and are a threat to other Pacific islands, the development of efficient and cost-effective methods to control them is desired. We compared the efficacy, cost, and effort required to remove brown treesnakes on 6-ha plots in forest scrub on Guam, using 2 methods: trapping and poison baiting. Toxic baits consisted of dead neonatal mice adulterated with 80-mg acetaminophen. To assess efficacy, we used mark-recapture methods to estimate snake abundance on plots 12 days before and 12 days after treatment. We also monitored bait-take or trap success for 20 days during treatment. From 6,304 trap-nights, we recorded 801 captures of 504 snakes on 6, 6-ha plots during a 51-day period. Snake populations on plots ranged from 41 to 107 prior to treatment. Using trapping to gauge survival of marked snakes, the 2 methods (trapping and baiting) had similar efficacies (0.05 to 0.1). Based on trapping, post-treatment population estimates ranged from 26 to 40, yielding reductions from estimated pre-treatment populations of 7 to 68% for both types of snake-removal treatments. Using post-treatment bait-take of unadulterated mice as an index of efficacy, poisoned baiting was twice as effective as trapping in diminishing snake activity. Trapped plots had post-treatment bait-take rates similar to reference plots (75%), whereas poison-baited plots had bait-take rates of 38%, suggesting that some snakes cannot be trapped and that baiting affects a wider range of the snake population. Because of the potential for baiting to impact more snakes, this method was about 1.67 times more cost effective than trapping. If baiting were to occur via aerial drop rather than via bait stations, the economic incentive for using baiting as a control strategy would be even greater. These observations will prove useful for managers making decisions about appropriate methods for control of brown treesnake populations.

ER - TY - JOUR T1 - Efficacy of aerial broadcast baiting in reducing brown treesnake numbers AN - 1221145037; 17395284 AB - The brown treesnake (Boiga irregularis) is an invasive predator that was introduced on Guam as a stowaway in cargo after World War II. Since then, the population has exploded, attaining 50 to 100 snakes per ha in some areas. The snake has caused the extirpation of ten of the 12 native forest bird species on Guam. The U.S. Department of Agriculture, Wildlife Services, has a program to deter the spread of snakes from Guam to other islands. Hand capture from fences, trapping, toxic bait stations, and canine inspection of outbound cargo methods are used in the control program in various localized and accessible areas. We investigated aerial delivery of toxic baits as a potential method for a broader landscape control of brown treesnakes. Treated baits were deployed on 6-ha of forest at 37.5 baits per ha. Snake activity was reduced by 80 to 85% by the third application of toxicant. Nontarget bait-take was limited. Of 80 telemetered baits aerially deployed, 30 (38%) baits were taken by snakes, one was taken by a toad (Bufo marinus), and one was taken by a monitor lizard (Varanus indicus). Mortality was observed in all 30 cases of bait-take by the snakes. No evidence of ill effects was observed in the toad or the monitor lizard after bait ingestion. Aerial delivery of toxic baits holds promise as an economical, targeted method to control invasive brown treesnakes over large areas of land.

Successfully dealing with the growing impacts of change on social-ecological systems depends on our ability to anticipate change. But traditional scientific tools are blunt instruments for studying a future that does not exist. We propose that futures research, a transdisciplinary field of inquiry that has been developing for more than 50 years, offers an underused but fruitful set of approaches to address this important challenge. A few futures research methods--notably several forms of scenario analysis--have been applied to environmental issues and problems in recent years. But futurists have developed an array of other useful methods for exploring possible, plausible, and preferable futures, important insights into the nature of change, and perspectives for thinking creatively and deeply about the future. We present an overview of futures research and its potential to enrich environmental planning and policy by offering a cross-fertilization of new ideas and approaches, providing a more complete view of emerging environmental problems, and facilitating the development of strategies to increase adaptive capacity and deal more effectively with surprises.

We modified the netlauncher by using customized nets to maximize the area of the capture zone. We captured 137 birds, comprising 12 species, in 23 attempts between July 2008 and October 2009 using this method. Capture success rates varied from 25 to 69% were comparable to success rates reported for other capture methods for these species. However, individual capture success for different net configurations varied greatly from 3 to 65%. Minimal injuries and 2 bird fatalities were reported. The netlauncher, using modified nets, proved to be a cost-, labor-, and time-efficient tool compared to what has been reported for other avian capture techniques. The netlauncher provides managers with a lightweight, flexible method of capture that does not use combustive or explosive propellants, and, thereby minimizes associated training and regulatory oversight.

At least 74 DGAT2 sequences from 61 organisms have been identified, but the expression of any DGAT2 as a partial or full-length protein in Escherichia coli had not been reported. The main objective of this study was to express and purify recombinant DGAT2 (rDGAT2) from E. coli for antigen production with a minor objective to compare rDGAT2 expression in yeast. A plasmid was engineered to express tung tree DGAT2 fused to maltose binding protein and poly-histidine (His) affinity tags. Immunoblotting showed that rDGAT2 was detected in the soluble, insoluble, and membrane fractions. The rDGAT2 in the soluble fraction was partially purified by amylose resin, nickel-nitrilotriacetic agarose (Ni-NTA) beads, and tandem affinity chromatography. Multiple proteins co-purified with rDGAT2. Size exclusion chromatography estimated the size of the rDGAT2-enriched fraction to be approximately eight times the monomer size. Affinity-purified rDGAT2 fractions had a yellow tint and contained fatty acids. The rDGAT2 in the insoluble fraction was partially solubilized by seven detergents with SDS being the most effective. Recombinant DGAT2 was purified to near homogeneity by SDS solubilization and Ni-NTA affinity chromatography. Mass spectrometry identified rDGAT2 as a component in the bands corresponding to the monomer and dimer forms as observed by SDS-PAGE. Protein bands with monomer and dimer sizes were also observed in the microsomal membranes of Saccharomyces cerevisiae expressing hemagglutinin-tagged DGAT2. Nonradioactive assay showed TAG synthesis activity of DGAT2 from yeast but not E. coli. The results suggest that rDGAT2 is present as monomer and dimer forms on SDS-PAGE, associated with other proteins, lipids, and membranes, and that post-translational modification of rDGAT2 may be required for its enzymatic activity and/or the E. coli protein is misfolded.

Difficulties in defining disease etiology, which can be exacerbated by abiotic factors, have limited progress toward developing alternatives to soil fumigation for disease control. However, the preponderance of data derived from studies of orchard soil biology employing multidisciplinary approaches has defined a complex of pathogens/parasites as causal agents of the disease. Approaches to manipulate microbial resources endemic to the orchard soil system have been proposed to induce a state of general soil suppressiveness to replant disease. Such a long-term strategy may benefit the existing orchard through extending the period of economic viability and reduce overall disease pressure to which young trees are exposed during establishment of successive plantings on the site. Alternatively, more near-term methods have been devised to achieve specific quantitative and qualitative changes in soil biology during the period of orchard renovation that may lead to effective disease suppression.

In the mid-2000s, the president of CMI was contemplating the future of the U.S. tart cherry industry and how CMI could contribute to industry success in the new century. The year 2002 had been a bell-weather in terms of production (a weather event resulted in an 80% crop loss across North America) and market competition (significant level of imports from outside North America for the first time in history). Changes in consumer preferences for food and food ingredients were putting significant downward pressure on demand for the industry's traditional products and creating incentives for new product development. The tart cherry industry had already proven willing to undertake major changes (e.g., transition to mechanical harvest in the 1970s, along with adjustments in orchard design and processing capacity, processing advances in the 1990s that significantly decreased the risk of cherry pits in the finished product). Would the existing policy and marketing support activities provided by CMI, although successful in the past, be able to move the industry forward? Was it time for another major change in this industry? Or were there marginal adjustments that could be made for survival?

An Instrumental Variable Approach with Panel Data AN - 1069197341; 17085373 AB - How much decoupled payments, such as direct payments in the U.S., affect agricultural production remains an open empirical question with implications for policy. Using data from multiple years of the Census of Agriculture, we exploit a provision of the 2002 Farm Act that departed from previous policy by making oilseeds eligible for direct payments, thus increasing payments to areas that historically produced more oilseeds. Our instrumental variable estimates, in contrast to OLS estimates, suggest that changes in payments over the period 2002 to 2007 had little effect on aggregate production at the ZIP-code level.

The pH value of both antimony-free and antimony supplemented culture media declined in the first five days to extremely acidic region (approximately pH 2) and did not change during the rest of cultivation period. There were no statistically significant, microbially mediated changes in pH of broth media supplemented with Sb(III) when compared to antimony-free control. While the biomass yield of antimony supplemented culture media (upto 100 mg, L super(-1)) during the exponential growth phase was identical to the antimony-free control, antimonyl tartrate however, had beneficial effect on fungal growth during the stationary growth phase. According to antimony accumulation results, A. niger strain efficiently reduced the uptake and enhanced the efflux of antimony during the first week of cultivation though later uptake of antimony was enhanced. The results indicate a relationship between the amount of antimony uptake and biomass growth at the stationary growth phase. This relates to possible tartrate function as carbon source.

Genomic analyses indicate that the serovars have a phylogeny congruent with their pathobiology and have an average substitution rate of less than one nucleotide per kilobase. In contrast, the gene that determines serovar specificity, ompA, has a phylogenetic association that is not congruent with tissue tropism and has a degree of nucleotide variability much higher than other genomic loci. The ompA gene encodes the major surface-exposed antigenic determinant, and the observed nucleotide diversity at the ompA locus is thought to be due to recombination and host immune selection pressure. The possible contribution of a localized increase in mutation rate, however, has not been investigated. Results: Nucleotide diversity and phylogenetic relationships of the five constant and four variable domains of the ompA gene, as well as several loci surrounding ompA, were examined for each serovar. The loci flanking the ompA gene demonstrated that nucleotide diversity increased monotonically as ompA is approached and that their gene trees are not congruent with either ompA or tissue tropism. The variable domains of the ompA gene had a very high level of non-synonymous change, which is expected as these regions encode the surface-exposed epitopes and are under positive selection. However, the synonymous changes are clustered in the variable regions compared to the constant domains; if hitchhiking were to account for the increase in synonymous changes, these substitutions should be more evenly distributed across the gene. Recombination also cannot entirely account for this increase as the phylogenetic relationships of the constant and variable domains are congruent with each other. Conclusions: The high number of synonymous substitutions observed within the variable domains of ompA appears to be due to an increased mutation rate within this region of the genome, whereas the increase in nucleotide substitution rate and the lack of phylogenetic congruence in the regions flanking ompA are characteristic motifs of gene conversion. Together, the increased mutation rate in the ompA gene, in conjunction with gene conversion and positive selection, results in a high degree of variability that promotes host immune evasion.

Merr.] in North America, and host-plant resistance is one potential management tool. In the current study, various F2-derived soybean selections with the Rag1 gene for resistance to soybean aphid were evaluated among F2-derived soybean selections without Rag1 and among contemporary soybean lines in a two-year field test. Overall, aphid levels per plant were over tenfold greater in 2006 than in 2005, but lines generally performed similarly relative to one another between years with regard to aphid-infestation levels. In both years, the Rag1 selections ILL4, ILL27, ILL35, ILL37, ILL64RR, ILL76RR, and ILL77RR had the lowest mean number of soybean aphids per plant. In 2005, three putative Rag1 selections-ILL26, ILL67RR, and ILL87-had intermediate aphid infestation levels greater than those of other Rag1 selections, and in 2006 ILL26 and ILL67RR also had intermediate aphid levels that did not differ from all other lines. Irrespective of the Rag1 gene, all soybean lines tested in 2006 had potentially injurious infestations ( [imageomitted] 799 soybean aphids per plant) that exceeded action thresholds for this pest. These results show varying levels of resistance among lines homozygous for the Rag1 resistance allele and that protection may be equivocal in years of heavy infestation by soybean aphid. Implications for testing putatively aphid-resistant soybean selections in the field and the potential for field deployment of aphid-resistant lines are discussed.

Catfish fillets were artificially contaminated with LM and Salmonella, dipped in a 1.5 % (30 min) trisodium phosphate solution (TSP), and cryogenically frozen. After 3 months frozen storage, Salmonella (2 log), but not LM, was inactivated on the fillets treated with the dip. This indicates that TSP dip followed by cryogenic freezing can be used to control Salmonella, but not LM, on catfish fillets.

It is an important anthropogenic greenhouse gas, and as a secondary air pollutant, it is present at high concentrations in rural areas far from industrial sources. It also reduces plant productivity by entering leaves through the stomata, generating other reactive oxygen species and causing oxidative stress, which in turn decreases photosynthesis, plant growth, and biomass accumulation. The deposition of O sub(3) into vegetation through stomata is an important sink for tropospheric O sub(3), but this sink is modified by other aspects of environmental change, including rising atmospheric carbon dioxide concentrations, rising temperature, altered precipitation, and nitrogen availability. We review the atmospheric chemistry governing tropospheric O sub(3) mass balance, the effects of O sub(3) on stomatal conductance and net primary productivity, and implications for agriculture, carbon sequestration, and climate change.

When carbon is removed from forests through harvest, a portion of the harvested carbon is stored in wood products, often for many decades. The United States Forest Service (USFS) and other agencies are interested in accurately accounting for carbon flux associated with harvested wood products (HWP) to meet greenhouse gas monitoring commitments and climate change adaptation and mitigation objectives. This paper uses the Intergovernmental Panel on Climate Change (IPCC) production accounting approach and the California Forest Project Protocol (CFPP) to estimate HWP carbon storage from 1906 to 2010 for the USFS Northern Region, which includes forests in northern Idaho, Montana, South Dakota, and eastern Washington. Results: Based on the IPCC approach, carbon stocks in the HWP pool were increasing at one million megagrams of carbon (MgC) per year in the mid 1960s, with peak cumulative storage of 28 million MgC occurring in 1995. Net positive flux into the HWP pool over this period is primarily attributable to high harvest levels in the mid twentieth century. Harvest levels declined after 1970, resulting in less carbon entering the HWP pool. Since 1995, emissions from HWP at solid waste disposal sites have exceeded additions from harvesting, resulting in a decline in the total amount of carbon stored in the HWP pool. The CFPP approach shows a similar trend, with 100-year average carbon storage for each annual Northern Region harvest peaking in 1969 at 937,900 MgC, and fluctuating between 84,000 and 150,000 MgC over the last decade. Conclusions: The Northern Region HWP pool is now in a period of negative net annual stock change because the decay of products harvested between 1906 and 2010 exceeds additions of carbon to the HWP pool through harvest. However, total forest carbon includes both HWP and ecosystem carbon, which may have increased over the study period. Though our emphasis is on the Northern Region, we provide a framework by which the IPCC and CFPP methods can be applied broadly at sub-national scales to other regions, land management units, or firms.

An experiment was established to examine rye (Secale cereale L.) residue management (RM) and N rates on cotton productivity. Three RM treatments (no winter cover crop (NC), residue removed (REM) and residue retained (RET)) and four N rates for cotton were studied. Cotton population, leaf and plant N concentration, cotton biomass and N uptake at first square, and cotton biomass production between first square and cutout were higher for RET, followed by REM and NC. However, leaf N concentration at early bloom and N concentration in the cotton biomass between first square and cutout were higher for NC, followed by REM and RET. Seed cotton yield response to N interacted with year and RM, but yields were greater with RET followed by REM both years. These results indicate that a rye cover crop can be beneficial for cotton, especially during hot and dry years. Long-term studies would be required to completely understand the effect of rye residue harvest on cotton production under conservation tillage.

Previously, we and others have shown that Bxb1 has catalytic activity in various eukaryotic species including Nicotiana tabacum, Schizosaccharomyces pombe, insects and mammalian cells. Results: In this work, the Bxb1 recombinase gene was transformed and constitutively expressed in Arabidopsis thaliana plants harboring a chromosomally integrated attP and attB-flanked target sequence. The Bxb1 recombinase successfully excised the target sequence in a conservative manner and the resulting recombination event was heritably transmitted to subsequent generations in the absence of the recombinase transgene. In addition, we also show that Bxb1 recombinase expressing plants can be manually crossed with att-flanked target transgenic plants to generate excised progeny. Conclusion: The Bxb1 large serine recombinase performs site-specific recombination in Arabidopsis thaliana germinal tissue, producing stable lines free of unwanted DNA. The precise site-specific deletion produced by Bxb1 in planta demonstrates that this enzyme can be a useful tool for the genetic engineering of plants without selectable marker transgenes or other undesirable exogenous sequences.

In this study, aflatoxin and non-aflatoxin producing isolates of A. flavus were grown separately on wet (20% water added), sterile or non-sterile cracked corn. Wet and dry cracked corn controls were included as needed. Secondary metabolic volatiles were identified and aflatoxin concentrations determined over a 12-day period. Volatiles unique to the toxigenic A. flavus isolates were determined by comparison with volatiles produced by the respective corn controls and the non-toxigenic A. flavus isolate. The number and identity of the volatiles produced by these A. flavus isolates varied by isolate, whether sterile or non-sterile corn was the substrate, and the sampling day. Overall, most of the volatiles were produced before day 8 after inoculation. Aflatoxin production was 10-fold lower on the sterile corn, compared to the non-sterile corn. Volatiles unique to the aflatoxin producing isolates were identified on both substrates after comparison with those produced by the non-aflatoxin producing isolate, as well as the corn control samples. Results indicate that several factors (substrate, fungal isolate, culture age) affect volatile and aflatoxin production by A. flavus.

The amount of biosorbed Sb(III) was highest at circumneutral pH (6.5) and at 150 rpm agitation speed. The biosorption capacity was not decreased in the presence of most of the tested coexisting anions (chloride, sulphate, phosphate, acetate). However, in the presence of carbonates a significant decrease was observed, possibly because of competition for binding sites. Both carboxyl and amide functional groups were identified as binding sites for Sb(III). According to the value of activation energy (54.7 kJ.mol super(-1)) it could be concluded, that the process involved in Sb(III) binding is chemisorption. The negative values of Gibbs free energy change (-8.8; -7.2 and -6.9 kJ.mol super(-1) for 30, 40 and 50 degree C, respectively) and enthalpy change (-37.9 kJ.mol super(-1)) indicate that Sb(III) binding was spontaneous and exotermic in nature. The equilibrium data were fitted by Langmuir and Freundlich isotherm. The value of maximum sorption capacity (153.3 mg.g super(-1)) was significantly higher than was reported for sorbents assessed for Sb(III) biosorption previously, which indicates a promising potential of beech sawdust for application in Sb(III) removal from contaminated waters.

Blume seedlings were raised in a growth chamber to determine the effects of light availability on shoot growth pattern, and basic leaf and stem growth. Lindera melissifolia seedlings exhibited a sympodial shoot growth pattern for 3months following emergence from the soil medium, but this pattern was characterized by a reduction in leaf blade area approximately 30days after emergence, followed by increases in leaf blade area. Seedlings receiving low light were 76% taller than seedlings receiving high light. Seedlings receiving low light also had larger leaf blade dimensions, blade area, seedling leaf area, and greater mass. Seedlings raised in high light had a greater proportional distribution of biomass in the roots, suggesting possible water stress from greater vapor pressure deficits. Furthermore, these seedlings displayed sharp angles of blade inclination and blade folding - acclimation that reduces exposure to light and subsequent higher leaf temperatures in open environments. These differences in morphological response to light resulted in high phenotypic variability in L. melissifolia seedlings. Lindera melissifolia seedling development showed a brief period of phenotypic plasticity, followed by ontogenetic plasticity. The short period of phenotypic plasticity may, however, have profound ecological implications for the conservation and recovery of this federally endangered shrub. Further experimentation should take into account the development of ontogenetic standards for comparisons of plant traits in addition to temporal standards.

In this study, the effect of O sub(3) at high and low atmospheric vapour pressure deficit (VPD) was evaluated in two genotypes of snap bean (Phaseolus vulgaris L.) (R123 and S156) used as O sub(3) bioindicator plants. Plants were grown in outdoor controlled-environment chambers in charcoal-filtered air containing 0 or 60 nl l super(-1) O sub(3) (12 h average) at two VPDs (1.26 and 1.96 kPa) and sampled for biomass, leaf area, daily water loss, and seed yield. VPD clearly influenced O sub(3) effects. At low VPD, O sub(3) reduced biomass, leaf area, and seed yield substantially in both genotypes, while at high VPD, O sub(3) had no significant effect on these components. In clean air, high VPD reduced biomass and yield by similar fractions in both genotypes compared with low VPD. Data suggest that a stomatal response to VPD per se may be lacking in both genotypes and it is hypothesized that the high VPD resulted in unsustainable transpiration and water deficits that resulted in reduced growth and yield. High VPD- and water-stress-induced stomatal responses may have reduced the O sub(3) flux into the leaves, which contributed to a higher yield compared to the low VPD treatment in both genotypes. At low VPD, transpiration increased in the O sub(3) treatment relative to the clean air treatment, suggesting that whole-plant conductance was increased by O sub(3) exposure. Ozone-related biomass reductions at low VPD were proportionally higher in S156 than in R123, indicating that differential O sub(3) sensitivity of these bioindicator plants remained evident when environmental conditions were conducive for O sub(3) effects. Assessments of potential O sub(3) impacts on vegetation should incorporate interacting factors such as VPD.

One existing effort is to incorporate the surface energy balance in the Simultaneous Heat and Water (SHAW) model into the Root Zone Water Quality Model (RZWQM)- In this study, an improved version of the RZ-SHAW (RZWQM-SHAW) hybrid model was tested for energy balance components, canopy and soil temperature, evapotranspiration (ET), and soil water content against eddy covariance data measured in a soybean canopy and against predictions of the original SHAW and RZWQM models. The experiment was first used previously to test the SHAW model for radiation energy fluxes within the canopy without examining the energy balance components, soil water balance, and soil temperature. The same parameters from mat study were used in both the SHAW model and RZ-SHAW hybrid model without any modification in this study. In terms of root mean squared error (RMSE), both RZ-SHAW and SHAW simulated net radiation, sensible heat, and latent heat well. However, the ground heat flux simulated by RZ-SHAW was less accurate, with RMSE of 28.9 W m(-2) compared to 22.6 W m(-2) with SHAW, which could be due to differences in simulated soil evaporation. Simulated soil temperature at both 1.5 cm and 4.5 cm depths with RZ-SHAW was comparable to that of SHAW, with RMSE of 2.18 degree C and 2.23 degree C, respectively, compared to 2.13 degree C and 2.20 degree C with SHAW. Similarly, simulated canopy temperature was essentially the same, with RMSE values of 1.77 degree C with RZ-SHAW and 1.69 degree C with SHAW. Simulated surface soil water content was reasonable for both models. Simulated ET had an RMSE of 0.069 cm d(-1) with RZ-SHAW and 0.074 cm d(-1) with SHAW. The new RZ-SHAW model was an improvement over the original RZWQM model in simulating soil temperature and moisture, in addition to its ability to provide complete energy balance and canopy temperature.

Cotton (Gossypium spp.) is a crop well-suited to precision agriculture and its inherent goals of increasing yields while minimizing environmental impacts. Ten cotton (G. hirsutum and G. barbadense) cultivars with differing leaf characteristics were evaluated in a greenhouse environment. Hyperspectral data collected with a handheld spectroradiometer were used to distinguish among the cultivars. The features extracted by principal component analysis and stepwise selection approaches were used for discriminant analysis. The best discrimination accuracy by selected wavelengths was 90.4% for G. hirsutum cultivars, 100% for G. barbadense cultivars, and 91.6% for pooled cultivars of the two species. Spectral wavelengths at 550 and 760 nm were most relevant to the discrimination between these two cotton species. Two vegetation indices, NDVI and PRI, were also investigated for any significant differences across cotton cultivars. The results demonstrated that hyperspectral radiometry has good potential for discrimination of G. hirsutum and G. barbadense cotton cultivars in early stages of growth.

As the retail shell-egg market offers these products to accommodate consumer demands, additional information is needed to ensure processing methodologies result in safe eggs from all egg sources. A study was conducted to determine if there were differences in the prevalence of coliforms, Salmonella, Listeria, and Campylobacter on and within eggs and in the environment of a sister flock of conventional cage and free-range laying hens. Microbial sampling occurred approximately every 6 wk between 20 and 79 wk of age. A random sampling of typical coliform colonies produced 371 viable isolates for biochemical identification. Twenty-nine genera or species of bacteria were identified. There was a significantly greater (P < 0.0001) prevalence of Campylobacter in the free-range nest box swabs compared with that in the free-range grass and conventional cage swab samples (number of positives: 8 nest box, 1 grass, 0 cage). Seven isolates of Listeria innocua were detected with no significant difference in prevalence between the treatments. Isolates were associated with eggshells (2 free-range floor, 1 cage) and the free-range environment (2 nest box, 2 grass). There were 21 Salmonella isolates detected between all sample locations, with no significant difference in the prevalence of Salmonella detection between the treatments. Additional studies are needed to fully understand the effect of alternative production methods on the prevalence of pathogens and coliforms associated with nest-run eggs and the production environment.

The USA and EU have aggressive mandates in place, which could further strengthen the linkages. The imposition of such mandates reduces the susceptibility of agricultural markets to energy volatility; but increases the supply-side impacts. Feedstock-specific mandates insulate the US biofuels from low oil prices; however, EU biofuel use remains linked with oil prices through aggregate fuel use. Overall, US markets are more vulnerable than the EU to supply-side shocks due to their product-specific mandates. Adapted from the source document.

Vegetative environmental buffers (VEB), which are specially designed combinations of trees, shrubs, and grasses, have shown promise in recent years for reducing odors at poultry operations, but they have seen less testing at swine farms. A field research project was conducted at two similar 8-barn swine finisher sites in Missouri to assess the effectiveness of VEBs in combination with fan deflectors for reducing downwind odor impacts from tunnel-ventilated swine barns. A VEB and fan plume deflectors were installed in spring 2009 at one 8-barn site, while the other site, with neither VEB nor fan plume deflectors, served as the control. Odor was monitored from July to November 2009, with trained human panelists at eight locations, upwind and downwind of the VEB, barns, and lagoons. Five aromatic volatile organic compounds (VOCs: phenol, 4-methylphenol, 4-ethylphenol, indole, skatole) were sampled from ambient air using sorbent tubes and gas chromatography/mass spectrometry. Compared to the control site, the VEB reduced odor concentrations (dilutions to threshold, D/T) by 49.1% in the VEB and by 66.3% at distance 15 m downwind of the VEB (p < 0.001). There was a larger percentage of non-detect odor concentrations (D/T < 2) at 15 m downwind for the VEB site (57.6%) as compared to the control site (16.4%). Mean upwind odor concentrations ranged from 1.4 to 2.4 D/T. Mean odor concentrations at the 150 m downwind location were not significantly different for the control (mean DT = 3.0) and the VEB site (mean DT = 3.5) (p = 0.42). Mean odor concentrations at 300 m downwind were not significantly different for the control (mean DT = 2.3) and the VEB site (mean DT = 2.5) (p = 0.47). In late 2010, a laboratory wind tunnel was used to compare VOC flux from VEB vegetation samples before and after rinsing. Wind tunnel VOC fluxes from vegetation were 78% to 98% lower after rinsing, qualitatively showing that particulate matter (PM) captured on the vegetation reduces VOC emissions.

The fresh QF, containing 55.4-56.6% moisture, decreased in water activity as salt content increased. Fresh QF had pH 6.42-6.31 and decreased (P < 0.05) 0.6-0.35 units over 8 weeks of storage in cheeses containing 1.0% or less added salt. Fresh QF had total aerobic plate counts of 2.28 plus or minus 0.05 log cfu times g super(-1) which increased (P< 0.05) 2-4 logs within the first 4 weeks; counts increased as salt levels decreased. Bacteria identified in the cheese were Pseudomonas, Microbacterium, and Paenibacillus and contributed to noticeable beta -casein proteolysis. Results indicated that salt levels in QF could be reduced to 1.5% before excessive microbial growth occurred and will be useful in developing low-salt Hispanic cheeses with optimum quality traits.Original Abstract: Queso Fresco-Kaese (QF) ist ein r spanischer Kaese mit hohem Wassergehalt, der bis zu 2, 5% Salz enthalten kann. QF wurden aus pasteurisierter, homogenisierter Milch ohne Zusatz von Saeureweckern hergestellt und mit Salz in Anteilen 0, 0, 5, 1, 1, 5, 2 und 2, 5% versetzt, um den Einfluss eines reduzierten Salzgehaltes auf die Gesamtkeimzahlen und die Proteolyse im Kaese waehrend einer 8-woechigen Reifung bei 4 degree C zu ermitteln. Der frische QF mit einem Wassergehalt von 55, 4-56, 6% zeigte eine abnehmende Wasseraktivitaet mit zunehmendem Salzgehalt. Frischer QF hatte pH Werte zwischen 6, 42 und 6, 31, die um 0, 6-0, 35 Einheiten im Verlauf einer 8-woechigen Lagerung in Kaesen mit 1% oder weniger Salz abnahmen (P<0,05). Die Gesamtkeimzahlen von frischem QF betrugen 2, 28 plus or minus 0, 05 log KbE/g und erhoehten sich um 2-4 Zehnerpotenzen innerhalb von 4 Wochen. Die Keimzahlen erhoehten sich bei abnehmenden Salzkonzentrationen. Die in den Kaesen identifizierten Bakterien waren Pseudomonas-, Microbacterium- und Paenibacillus-Arten, die deutlich zur Proteolyse des ss-Caseins beitrugen. Die Ergebnisse zeigten, dass die Salzkonzentration in QF auf 1, 5% reduziert werden kann, bevor es zu einem exzessiven Keimvermehrung kommt. Die Entwicklung spanischer Kaese mit niedrigem Salzgehalt und optimalen Qualitaetsmerkmalen ist somit moeglich.

In this study, we characterized the rumen microbiota of pre-ruminant calves fed milk replacer using two approaches, pyrosequencing of hypervariable V3-V5 regions of the 16S rRNA gene and whole-genome shotgun approach. Fifteen bacterial phyla were identified in the microbiota of pre-ruminant calves. Bacteroidetes was the predominant phylum in the rumen microbiota of 42-day-old calves, representing 74.8% of the 16S sequences, followed by Firmicutes (12.0%), Proteobacteria (10.4%), Verrucomicrobia (1.2%) and Synergistetes (1.1%). However, the phylum-level composition of 14-day-old calves was distinctly different. A total of 170 bacterial genera were identified while the core microbiome of pre-ruminant calves included 45 genera. Rumen development seemingly had a significant impact on microbial diversity. The dazzling functional diversity of the rumen microbiota was reflected by identification of 8298 Pfam and 3670 COG protein families. The rumen microbiota of pre-ruminant calves displayed a considerable compositional heterogeneity during early development. This is evidenced by a profound difference in rumen microbial composition between the two age groups. However, all functional classes between the two age groups had a remarkably similar assignment, suggesting that rumen microbial communities of pre-ruminant calves maintained a stable function and metabolic potentials while their phylogenetic composition fluctuated greatly. The presence of all major types of rumen microorganisms suggests that the rumen of pre-ruminant calves may not be rudimentary. Our results provide insight into rumen microbiota dynamics and will facilitate efforts in formulating optimal early-weaning strategies.

The calibration range of Pt determination by ET AAS was 0.11-2.15 mu mol l super(-1) with RSD better than 8 and 12% for within-run and between-run precision, respectively. The method was successfully used for the investigation of some pharmacokinetic parameters to compare intravenous (one cycle) and intraperitoneal (four cycles) infusion of carboplatin. The Pt concentration declined in blood serum by power and exponential function following a both ways of dose administration. From the comparison of plotted Pt concentrations in blood serum versus time it was evident that area under the curve (AUC) was different for all five cycles. The half-life of Pt in blood serum (t sub(1/2)) ranged from 10.5 to 12 h and around 1.33 h for intraperitoneal and intravenous infusion, respectively. Additionally, up to 51.6-56.2% and only 12.5% of initial Pt concentration (18-82 mu mol l super(-1)) was found in blood serum after 10 h from the dose administrated intraperitoneally and intravenously, respectively. Anyway, the obtained results showed that the intraperitoneal administration of carboplatin is more favourable.

The CCW is one of 14 benchmark watersheds in the USDA-ARS Conservation Effects Assessment Project (CEAP) watershed assessment study. Two input parameter sets were developed for OMS-J2K evaluation: (1) a "base parameter set" with parameter values taken from previous simulation studies where J2K was applied to watersheds with characteristics similar to the CCW, and (2) an "adjusted parameter set" with modifications to input parameters related to evapotranspiration, soil water storage, and soil water lateral flow. Comparisons of daily, average monthly, and annual average simulated and observed flows for the 1997-2005 simulation period using the base parameter set resulted in Nash-Sutcliffe efficiency (E(ns)), root mean square deviation (RMSD), and relative error (PBIAS) coefficients of 0.34 to 0.48 for E(ns), 1.50 to 8.79 m(3) s(-1) for RMSD, and -18.43% for PBIAS. All statistical evaluation coefficients improved for the adjusted parameter set (e.g, 0.44 to 0.59 for E(NS), 0.87 to 7.73 m(3) s(-1) for RMSD, and -8.59% for PBIAS). The ranges of E(NS) and PBIAS values for uncalibrated or manually adjusted streamflow predictions in this study (using both parameter sets) were similar to others reported in the literature for various watershed models. This study represents the first attempt to develop and apply a complex natural resource system model under the OMS. The results indicate that the OMS-J2K watershed model was able to reproduce the hydrological dynamics of the CCW and should serve as a foundation on which to build a more comprehensive model to better quantify water quantity and quality at the watershed scale. In particular, the topological routing scheme employed by OMS-J2K (thus allowing the simulation of lateral processes vital for the modeling of runoff concentration dynamics) is much more robust than the quasi-distributed routing schemes used by other watershed-scale natural resource. models and represents a noteworthy advancement in hydrological modeling toward deriving suitable conservation management scenarios.

Verona) plants to Cr(III)-nitrate was investigated. The applied metal concentration varied in the range from 6 to 480 mu mol L super(-1) (i.e. 0.312-12.480 mg L super(-1)). Cr(III) application resulted in reduced length, fresh mass as well as dry mass of rapeseed plant organs and the inhibitory effect of Cr(III) increased with increasing metal concentration in the external solution. The roots were more sensitive to Cr(ITJ) treatment than the shoots. Due to Cr(III) application significant decrease in the concentration of assimilation pigments (chlorophyll alpha , chlorophyll b, caro-tenoids), proteins and reduced thiol groups in rapeseed leaves was observed. As an indicator of lipid peroxida-tion, malondialdehyde contents were used, expressed as thiobarbituric acid reactive substances (TBARS). The concentration of TBARS rose with the increasing Cr(III) concentration. Accumulated Cr concentration in roots of rapeseed cultivar Verona showed linear increase with increasing external Cr(III) concentration reaching 22810 mg Cr kg super(-1) at treatment with 480 umol L super(-1) Cr(III), however translocation of Cr into the shoots was low, what was reflected in small values of translocation factors (0.0015-0.0330).

The green lacewing. Chrysoperla sinica (Tjeder). is a polyphagous natural enemy attacking several pests on various crops in China. We investigated the effect of feeding it different species of prey on its pre-imaginal development, survival, adult longevity and fecundity under laboratory conditions. The prey species tested were nymphs of Aphis glycines Matsumura. cotton aphid Aphis gossypii Glover, peach aphid Myzus persicac Sulzer. corn aphid Rhopalosiphum maidis Fitch and cowpea aphid Aphis craccivora Koch, and eggs of the rice grain moth. Coreyra cephalonica Stainin. None of these species of prey affected the pre-imaginal survival or percentage survival of the eggs of the predator. However, eggs of C. cepha-lonica and nymphs of M. persicae and A. glycines were the best of the prey species tested, in that when fed on these species the pre-imaginal developmental period of C. sinica was shorter and its adult longevity, fecundity and percentage survival greater than when fed the other species of prey. In contrast, when fed nymphs of A. craccivora the pre-imaginal development period was longer, adult longevity shorter and fecundity lower.

While there are alternative bullet technologies on the market that are suitable for hunting, these alternatives have not been adequately researched and tested for use in professional wildlife damage management (WDM). Differences between hunting and WDM include an increased level of precision necessary for safe WDM work, potentially greater distances for shots fired at targets, a need for instant incapacitation, and overall cost-effectiveness. To determine the applicability of lead-free bullets for WDM, we reviewed current lead-free bullet technologies and examined their limitations and benefits based on ballistic theory and available research. We found that there has not been sufficient research or experience with lead-free ammunition in the unique shooting scenarios used in WDM. Some of the issues identified by our review include a reduced theoretical precision of lead-free bullets due to a mismatch between bullet length and twist rate of the rifle barrel, lower performance of lead-free ammunition at greater ranges compared with lead-based bullets, and greater chance of bullets passing through targets and striking a nontarget object or animal. While some of these deficiencies may be overcome with new equipment and decreased target ranges, there are still situations where lead-based ammunition may be the safest and most practical option.

Starling use of CAFOs is known to vary in response to weather; starling control operations on CAFOs often are timed to coincide with favorable environmental conditions to maximize take. The totality of this information suggests that disease risks in CAFOs associated with starlings may be influenced by environmental factors, such as temperature. In this study, we assessed the risk of Salmonella enterica contamination of cattle feed by modeling the interaction between starling numbers and ambient air temperatures using data previously reported from Texas CAFOs. We compared these interaction models to the previously published additive models for S. enterica contamination of cattle feed using an information-theoretic approach to model selection that ranked and weighted models in terms of their support by the data, using bias-adjusted Akaike's Information Criterion (AIC sub(C)) and Akaike weights (Wi). Our results indicate that the interaction between European starlings and ambient air temperature better explained the occurrence of S. enterica in cattle feed than any of the previously reported models. Specifically, the risk of S. enterica contamination of cattle feed by starlings was greatest when winter temperatures were highest (10 degree C). Thus, we conclude that the risk of S. enterica contamination of cattle feed by starlings will be worst on the few winter days when daytime high temperatures are above freezing and large numbers of birds are present. Because these conditions will be most common in the late winter and early spring, we recommend that starling control operations on feedlots and dairies be conducted as early in the winter as possible to mitigate the risks of disease created by large foraging flocks of starlings.

During March 2009 through December 2010, we collected serum samples from 4,479 feral swine from 13 states, and 159 animals tested were seropositive for brucellosis. No difference in likelihood of infection was found between males and females, but adults were more likely than sub-adults or juveniles to be exposed to brucellosis. Feral swine sampled during winter months also were more likely to be seropositive than animals sampled during other seasons. Apparent prevalence varied among states, and seropositive animals often were clustered in specific counties within a state. We recommend improved diagnostics and stricter regulations on movement of feral swine both intra- and inter-state to minimize further spread of the disease and to decrease the risk of reintroduction of brucellosis into livestock.

[B.] microplus) collectively referred to as cattle fever ticks (CFT), were eradicated from areas in the United States (Pound et al. 2010). These ticks transmit Babesia bovis and B. bigemina, which are the causative agents in cattle of the potentially fatal protozoan disease commonly known as Texas fever, cattle fever, or bovine piroplasmosis. The ticks are a 1-host species that attach themselves to an individual host as larvae and feed on the hosfs blood, molt to nymphs that feed again, and, subsequently, develop to adults. Adults mate on the host, then, females engorge with blood, detach, and drop to the ground where they lay a clutch of several thousand eggs. The eggs hatch into larvae that attach themselves to host animals, and the life cycle continues. These ticks are host-specific (Sonenshine 1993) and will feed successfully only on large ruminants (Sonenshine et al. 2002), including cattle, cervids, and equines (e.g., horses and mules). While individual ticks occasionally are found attached opportunistically to swine, canines, felines, ovines, caprines, and other nonruminants, they are unable to feed and develop sufficiently to produce gravid females. Therefore, the only hosts that were initially considered to be important in the tick eradication effort were cattle, horses, and mules (George 1990). It was not until eradication efforts failed because of high densities of white-tailed deer (Odocoileus virginianus) in South Florida that deer were considered to be important alternative hosts. Cattle ticks were finally eradicated in Florida, but only after extensive depopulation of deer herds.

We provide a synthesis of adaptive management of double-crested cormorants in the Les Cheneaux Islands (LCI), Brevoort Lake, and Drummond Island, Michigan from 2004 to 2007. The LCI management focused on reducing numbers of nesting cormorants in the region as a means of improving the yellow perch (Perca flavescens) population and fishery. At Brevoort Lake and Drummond Island, management focused on lethal and nonlethal harassment of spring migrating cormorants to reduce their foraging on spawning walleye (Sander vitreus) and yellow perch and to improve those fisheries and increase fish populations. At each location, management efforts reduced cormorant foraging, and fishery data indicated increased abundance of sport fish species. The 3 locations combined provided evidence for the underlying hypotheses that cormorants can influence mortality of local sport fish populations and that short-term management goals have been met. Continuation of adaptive management and monitoring programs will determine whether the improvement of targeted sport fisheries through cormorant management is sustainable.

ER - TY - JOUR T1 - Loxoribine pretreatment reduces Salmonella Enteritidis organ invasion in 1-day-old chickens AN - 1011204387; 16483643 AB - Young poultry exhibit a transient colonization by some food-borne pathogens, including Salmonella, during the first week of life that stems from immature innate and acquired defense mechanisms. Consequently, modulation of the hosts' natural immune response is emerging as an important area of interest for food animal producers, including the poultry industry. Toll-like receptor (TLR) agonists have been shown to boost the innate immune response in young chickens and increase their resistance to colonization by Salmonella enterica serovar Enteritidis. The objective of the present study was to determine if pretreatment with loxoribine, a TLR7 agonist and immune modulator, protects young chicks from Salmonella Enteritidis organ invasion. Loxoribine (0-100 mu g) was administered intra-abdominally to 1-d-old broiler chicks, and 4 h later, the birds were challenged orally with Salmonella Enteritidis. Twenty-four hours postchallenge, birds were euthanized and the liver and spleen aseptically removed and cultured for Salmonella Enteritidis. This was carried out on 3 separate occasions using 26 to 50 chicks per dose per experiment. Pretreatment of chicks with loxoribine (6.25-25 mu g) significantly (P less than or equal to 0.05) reduced liver and spleen organ invasion by Salmonella Enteritidis. Higher doses (50-100 mu g) of loxoribine had no effect. The results obtained in this study indicate that there is a potential application for using loxoribine to increase protection of young chicks when they are most susceptible to infections with SALMONELLA: JF - Poultry Science AU - Swaggerty, CL AU - He, H AU - Genovese, K J AU - Duke, SE AU - Kogut, M H AD - USDA, Agricultural Research Service/Southern Plains Agricultural Research Center (ARS/SPARC), 2881 F&B Rd Y1 - 2012 PY - 2012 DA - 2012 SP - 1038 EP - 1042 PB - Poultry Science Association, Inc.

Using 250-mL baffled flasks, culture volumes of 50, 100, 150, and 200 mL were grown in a shaker incubator at 350 rpm and 28 degree C. Dissolved oxygen (DO) was continuously monitored using a non-invasive oxygen monitoring system. Culture volumes of 50 mL maintained DO concentrations above 10% throughout the 3-day growth period and accumulated biomass and produced blastospores more rapidly (1.2109 blastospores mL-1 in 2 days) than the other culture volumes tested. Dissolved oxygen was depleted in culture volumes of 100, 150, and 200 mL after 20.5, 16.8, and 13.5 h, respectively. The DO in 150 and 200 mL cultures remained exhausted (20% DO) for I. fumosorosea growth in 100-L bioreactors resulting in blastospore production (1.1109 blastospores mL-1 in 2 days) comparable to highly aerated, low volume shake flask cultures. In addition, maintaining higher DO levels resulted in increased blastospore production by cultures of I. fumosorosea grown on low-cost nitrogen sources (cottonseed meal and soy flour) that previously elicited excessive hyphal growth. These studies showed that oxygen availability is essential for significant yeast-like growth by I. fumosorosea cultures and that continuous monitoring of oxygen concentrations in shake flask cultures can be used to establish aeration conditions for bioreactors.

Predicting gas diffusivity from the Campbell soil-water retention model. Soil Sci. 161:366-375) models. Soil bulk density and volumetric soil water content ([thetas]v) at 0-10 cm were measured on 14 April, 2 June and 12 July 2005 at 0-10 cm depth in no-till (NT) and conventional till (CT) malt barley and undisturbed soil grass-alfalfa (UGA) systems. Air-filled porosity ( epsilon ) was calculated from total soil porosity and [thetas]v measurements. Both soil air porosity and estimated CO2 diffusivity at the 0-10 cm depth were significantly affected by tillage. Results of CO2 diffusion coefficients in the soil followed trends similar to those for soil epsilon data. The CT tended to have significantly greater estimated soil CO2 diffusion coefficients than the NT and UGA treatments. The relationship between D/D0, and air-filled porosity was well described by a power (R2 = 0.985) function. The model is useful for predicting CO2 gas-diffusion coefficients in undisturbed and tilled soils at various ranges of epsilon where actual gas D measurements are time-consuming, costly and infeasible.

Field studies and chemical analyses identified the predominant toxic plant as western aster (Symphyotrichum ascendens, previously Aster ascendens), which contained over 4,000 ppm Se (dry weight). Several dead animals that were necropsied had acute severe myocardial necrosis characterized by edema and myocyte swelling, with hypereosinophilia, clumping, and coagulation of myocardial proteins. Whole blood from 36 surviving steers was collected and analyzed, and 10 steers with elevated Se concentrations were selected for close monitoring and clinical evaluations. Each steer was weighed, and serum, blood, liver, skeletal muscle, and hair were regularly collected after removal from the Se-contaminated range. One animal that died 18 days after exposure was necropsied and exhibited severe multifocal myocardial fibrosis with extensive hepatic congestion, degeneration, and hemosiderosis. At 180 days postexposure, 2 of the 10 steers were euthanized, and tissue samples were collected. Both steers had rare, small fibrotic foci in their hearts. The Se elimination half-lives from serum, whole blood, liver, and muscle of the recovering steers were 40.5 plus or minus 8.2, 115.6 plus or minus 25.1, 38.2 plus or minus 5.0, and 98.5 plus or minus 19.1 days, respectively. The Se concentration in hair reached a peak of 11.5 plus or minus 5.3 ppm at 22 days postexposure. The findings indicate that cattle are sensitive to acute Se toxicosis caused by ingestion of Se-accumulator plants, with myocardial necrosis as the primary lesion. Some poisoned animals may develop congestive heart failure weeks after the toxic exposure, and in the current study, Se was slowly excreted requiring a relatively long withdrawal time.
