This study compared three commercial broiler chicken lines using an experimental model of necrotic enteritis. Day-old male Cobb, Ross, and Hubbard broilers were orally infected with viable C. perfringens and E. maxima and fed a high-protein diet to promote the development of experimental disease. Body weight loss, intestinal lesions, and serum antibody levels against alpha -toxin and necrotic enteritis B-like (NetB) toxin were measured as parameters of disease susceptibility and host immune response. Cobb chickens exhibited increased body weight loss compared with Ross and Hubbard breeds and greater gut lesion severity compared with Ross chickens. NetB antibody levels were greater in Cobb chickens compared with the Ross or Hubbard groups. These results suggest that Cobb chickens may be more susceptible to necrotic enteritis in the field compared with the Ross and Hubbard lines.

A new, computationally efficient algorithm for distributing the complex and heterogeneous effects of wind on snow distributions was developed. The distribution algorithm uses terrain structure, vegetation, and wind data to adjust commonly available precipitation data to simulate wind-affected accumulations. This research describes model development and application in three research catchments in the Reynolds Creek Experimental Watershed in southwest Idaho, USA. All three catchments feature highly variable snow distributions driven by wind. The algorithm was used to derive model forcings for Isnobal, a mass and energy balance distributed snow model. Development and initial testing took place in the Reynolds Mountain East catchment (0.36km2) where R2 values for the wind-affected snow distributions ranged from 0.50 to 0.67 for four observation periods spanning two years. At the Upper Sheep Creek catchment (0.26km2) R2 values for the wind-affected model were 0.66 and 0.70. These R2 values matched or exceeded previously published cross-validation results from regression-based statistical analyses of snow distributions in similar environments. In both catchments the wind-affected model accurately located large drift zones, snow-scoured slopes, and produced melt patterns consistent with observed streamflow. Models that did not account for wind effects produced relatively homogenous SWE distributions, R2 values approaching 0.0, and melt patterns inconsistent with observed streamflow. The Dobson Creek (14.0km2) application incorporated elevation effects into the distribution routine and was conducted over a two-dimensional grid of 6.67105pixels. Comparisons with satellite-derived snow-covered-area again demonstrated that the model did an excellent job locating regions with wind-affected snow accumulations. This final application demonstrated that the computational efficiency and modest data requirements of this approach are ideally suited for large-scale operational applications.

In this paper we present a comparison of several methods for determining precipitation phase using 12years of hourly precipitation, weather and snow data from a long-term measurement site at Reynolds Mountain East (RME), a headwater catchment within the Reynolds Creek Experimental Watershed (RCEW), in the Owyhee Mountains of Idaho, USA. Methods are based on thresholds of (1) air temperature (Ta) at 0 degree C, (2) dual Ta threshold, -1 to 3 degree C, (3) dewpoint temperature (Td) at 0 degree C, and (4) wet bulb temperature (Tw) at 0 degree C. The comparison shows that at the RME Grove site, the dual threshold approach predicts too much snow, while Ta, Td and Tw are generally similar predicting equivalent snow volumes over the 12year-period indicating that during storms the cloud level is at or close to the surface at this location. To scale up the evaluation of these methods we evaluate them across a 380m elevation range in RCEW during a large mixed-phase storm event. The event began as snow at all elevations and over the course of 4h transitioned to rain at the lowest through highest elevations. Using 15-minute measurements of precipitation, changes in snow depth (zs), Ta, Td and Tw, at seven sites through this elevation range, we found precipitation phase linked to the during-storm surface humidity. By measuring humidity along an elevation gradient during the storm we are able to track changes in Td to reliably estimate precipitation phase and effectively track the elevation of the rain/snow transition during the event.

Treatments were assigned to pastures (two pastures/treatment) and cows had ad libitum access to one of three free-choice minerals: (1) no supplemental selenium (Se), (2) 26 mg of supplemental Se from sodium selenite per kilogram, and (3) 26 mg of supplemental Se from seleno-yeast per kilogram (designed mineral intake=113 g/cow daily). Data were analyzed using a mixed model; year and pasture were the random effects and treatment was the fixed effect. At the beginning of the calving and breeding seasons, cows supplemented with Se had greater (P<0.01) whole blood Se concentration (WBSe) and glutathione peroxidase activities (GSH-Px) than cows receiving no supplemental Se; cows fed seleno-yeast had greater (P less than or equal to 0.05) WBSe than cows fed sodium selenite, but GSH-Px did not differ (P greater than or equal to 0.25) between the two sources. At birth and near peak lactation (late May), calves from cows supplemented with Se had greater (P<0.01) WBSe than calves from cows fed no Se and calves from cows fed seleno-yeast had greater (P less than or equal to 0.01) WBSe and GSH-Px than calves from cows fed sodium selenite. Thyroxine (T sub(4)), triiodothyronine (T sub(3)), and the T sub(4):T sub(3) ratio in calves did not differ among treatments (P greater than or equal to 0.35). At birth, insulin-like growth factor 1 (IGF-1) was greater (P=0.02) in calves nursing cows with no supplemental Se than in ones with supplemental Se; in calves nursing cows with supplemental sodium selenite, IGF-1 did not differ (P=0.96) from ones offered supplemental seleno-yeast. Selenium supplementation of gestating beef cows benefited cows and calves by increasing WBSe and GSH-Px. The use of seleno-yeast as a Se supplement compared to sodium selenite increased the WBSe of both cows and their calves without affecting the T sub(4) to T sub(3) conversion or IGF-1 concentrations.

The following Cd and/or Si treatments were used: 5 Cd; 10 Cd; 100 Cd; 5 Cd + 0.08 Si; 10 Cd + 0.08 Si; 100 Cd + 5 Si treatments (Cd concentration in mu M, Si concentration in mM). The plant growth, photosynthetic pigments content, antioxidant enzymes activities (POX, SOD, CAT), Cd and Si accumulation, translocation and cell wall deposition of the maize plants was observed. Changes in the endodermal cell walls development and late metaxylem elements lignification due to Cd and/or Si treatment were also evaluated. The negative effect of Cd (5 and 10 mu M) on the growth parameters was alleviated by Si at 0.08 mM. The positive effect of Si was not observed at higher Cd and Si concentrations. This indicates that the alleviating effect of Si on Cd toxicity depends on the Cd and Si concentrations. Plants responded to Cd toxicity by an increase of antioxidant enzyme activity. Silicon addition in Cd + Si treatment stimulated an increase in the activity of antioxidant enzymes in comparison with the Cd treatment. Chlorophyll and carotenoid content in the Cd treated plants was not significantly affected by Si. The young maize plants retained much more Cd in their roots as they translocated into the shoots. 5 Cd + 0.08 Si and 10 Cd + 0.08 Si treatments correlated with an increase in Cd concentration in the roots and shoots, and in the cell walls. Silicon caused a slight decrease of the Cd translocation into the shoots in 5 Cd + 0.08 Si and 10 Cd + 0.08 Si treatments. Negative correlation between the root Cd cell wall deposition and Cd translocation was observed. Cadmium and/or Si altered root anatomy. Cadmium enhanced suberin lamellae development and late metaxylem lignification; silicon in Cd + Si treatments accelerated suberin lamellae deposition and enhanced the tertiary endodermal cell walls formation in comparison with Cd treatments. Negative correlation between the endodermal cell walls development and Cd translocation was observed.

One important step in reducing agricultural contribution is to accurately account for all sources of plant available nutrients so that only needed nutrients are applied. In this study, three fertilizer rate treatments were evaluated: no fertilizer (control), traditional rate, and reduced rate based on a recently-developed enhanced soil test methodology. For each of nine sites in Texas , fertilizer data (formulation, rate, cost, and application date) and crop data (yield, price, and harvest date) were recorded, and economic throughput (profit) was determined. In this four year study, fertilizer rates were reduced 30%-50% (and fertilizer costs reduced 23%-39%) based on enhanced soil test methodology recommendations for wheat, corn, oats, and grain sorghum, but yields were not significantly reduced (0%-6%) and oat yields actually increased 5%. Profit decreased <1% for corn and increased 7%-18% for wheat, oats, and grain sorghum with reduced fertilizer rates. Although these changes were not statistically significant, they do represent benefit through increased profit potential and decreased input cost and production risk. In only 6% of the time was the traditional fertilizer rate the most profitable, compared to 51% for the unfertilized treatment and 43% for the enhanced soil test treatment. These results do not indicate that fertilizer application should be avoided but that fertilizer rates should be carefully chosen considering all sources of plant available nutrients (e.g., mineralization, irrigation water, nutrients deeper in the soil profile) to ensure that fertilizer is applied at the optimal rate.

To achieve this goal, a cost-effective machine vision inspection prototype was built, which consisted of a low-cost color camera, LED lights, and a generic bi-cone conveyor. Algorithms were developed for accurate estimation of pixels per unit dimension from images acquired under the close-range imaging configuration and for real-time estimation of apple orientation, shape, and maximum equatorial diameter. The machine vision system was tested and evaluated for 'Delicious' (D), 'Empire' (EM), 'Golden Delicious' (GD), and 'Jonagold' (JG) apples at a speed of four fruit per second. The variable pixels per unit dimension method achieved superior results for area estimation, compared to the conventional image distortion correction and area estimation methods. The orientation estimation algorithm had 87.6% and 86.2% accuracies for D and GD apples, respectively, within (plus-or-minus sign)20 degree of actual fruit orientation, but it performed less satisfactorily for round-shaped EM and JG apples. The machine vision system achieved good fruit maximum equatorial diameter estimations, with an overall root mean squared error of 1.79 mm for the four varieties of apple, and it had a two-size grading error of 4.3%, versus 15.1% by a mechanical sizing machine. The system provides a cost-effective means for sorting apples for size.

Existing studies are based on modest sample sizes because of the rarity of this endangered species and the difficulty of radio-tracking bats. Our objectives were to determine resource selection by foraging Indiana bats during the maternity season and to compare resource use between pregnant and lactating individuals. We used an information theoretic approach with discrete choice modeling based on telemetry data to evaluate our hypotheses that land cover, percent canopy cover, distance to water, and prescribed fire affected the relative probability a point was used by a foraging Indiana bat. We fit models for individual bats and a population-level model based on all individuals with a random factor to account for differences in sample size among individuals. We radio-tracked 29 individuals and found variation in resource selection among individuals. However, among individuals with the same supported covariates, the magnitude and direction of the covariates were similar. Eighteen bats selected areas with greater canopy closure and 5 of 6 bats that had areas burned by low-intensity prescribed fire in their home range selected burned areas. Resource selection was related to land cover for 13 individuals; they selected forest and shrubland over agricultural land, which composed >50% of the landscape within 10km. We found no support for our hypothesis that resource selection was related to individual reproductive condition or Julian date in our population-level model indicating habitat selection was not determined by reproductive status or date within the maternity season. Land use or forest management that greatly reduces canopy cover may have a negative impact on Indiana bat use. Maintaining forest cover in agricultural landscapes is likely critical to persistence of maternity colonies in these landscapes. Sites managed with low severity prescribed fire may be selected by some individuals because of reduced understory vegetation. [copy 2013 The Wildlife Society.

Runoff from feedlot surfaces is diverted into settling basins. The storage capacity of the settling basins will be substantially reduced if large quantities of solid material are transported in runoff from the feedlot surfaces. The objective of this study was to identify the hydraulic conditions that will not move unconsolidated surface material located within feedlots in order to minimize sediment transport. Selected sizes and a composite sample of unconsolidated surface material were placed within 0.75 m wide by 4.0 m long metal frames. Flow was then introduced at the top of the frames in successive increments. The discharge rate and flow velocity necessary to cause movement of unconsolidated surface material was measured. Hydraulic measurements were used to determine the ratio of critical flow depth to particle diameter, critical flow rate, critical flow velocity, critical shear velocity, critical Reynolds number, critical shear stress, critical dimensionless shear stress, and critical boundary Reynolds number. Measurements of these parameters for the composite material were 0.556, 0.499 L s(-1), 0.0787 m s(-1), 0.0643 m s(-1), 695, 4.12 Pa, 0.0436, and 1040, respectively. Darcy-Weisbach roughness coefficients were calculated for each particle size class and the composite sample at varying flow rates. The information presented in this study can be used to identify the hydraulic conditions required to not move unconsolidated surface material located within feedlots in order to minimize sediment transport.

Both empirical and process-based models have been developed to estimate NH(3) emissions from various livestock production systems; however, little work has been conducted to assess their accuracy for large, open-lot feedyards. To validate Manure-DNDC, a process-based biogeochemical model, Manure-DNDC-simulated daily NH(3) fluxes were compared to emission data collected from two commercial feedyards, feedyard A and feedyard E, in the Texas High Plains from 2007 to 2009. Model predictions were in good agreement with observations from both feedyards (p < 0.001) and had high sensitivity to variations in air temperature and dietary crude protein (CP) concentration. Predicted mean daily NH(3) flux densities for the two feedyards had 71% to 78% agreement with observed values. In addition, Manure-DNDC estimates of annual feedyard emissions were within 3% to 15% of observations for the two feedyards, whereas a constant emission factor currently in use by the USEPA underestimated feedyard emissions by as much as 79%. The results from this study indicate that Manure-DNDC can be used to quantify average feedyard NH(3) emissions, assist with NH(3) emissions reporting, provide accurate information for legislators and policy makers, investigate methods to mitigate NH(3) loss, and help evaluate the effects of specific management practices on farm nutrient balances.

In the Sahel of Africa, where malaria vector mosquitoes breed in shallow, temporary pools, topography is a significant environmental factor in the formation and persistence of the breeding habitat. Such breeding pools are commonly several meters to tens of meters in size and host the vast majority of malaria vector mosquitoes. Therefore, high-resolution topography is necessary in order to model breeding habitat productivity mechanistically. This study investigates the role of topography in pool persistence and productivity, and the utility of remote sensing of high-resolution topography for simulating mosquito breeding. Combinations of various synthetic topographic configurations and rainfall scenarios are simulated using a coupled hydrology and entomology model to assess the role of pool catchment size in combination with rainfall variables as a predictor of pool productivity. Rainfall intensity has the strongest influence on pool persistence when compared to duration and frequency. A threshold rainfall frequency exists for a given topographic configuration in order for the pool to persist longer than the development time of larvae and thus for the pool to be productive. In addition, synthetic aperture radar was used to generate high-resolution topography for application in hydrologic and entomology modeling. A digital elevation model generated with radar interferometry does not have enough vertical accuracy (RMS error = 7.7 m) to simulate pools that are tens of meters across and centimeters deep. We conclude that repeat-pass interferometry using two radar images is not a viable method to acquire topography to model pools or confidently delineate pool catchment areas. Additional research is needed to further explore the potential of remote sensing, particularly interferometric methods, as a tool in predicting topographic influences of malaria risk at a high spatial resolution.

HABITAT PATCH SIZE AND SPACING TO CONSERVE A THREATENED SPECIES AN - 1434014336; 18496848 AB - Abstract. We present results of a spatially explicit, individual-based stochastic dispersal model (HexSim) to evaluate effects of size and spacing of patches of habitat of Northern Spotted Owls (NSO; Strix occidentalis caurina) in Pacific Northwest, USA, to help advise recovery planning efforts. We modeled 31 artificial landscape scenarios representing combinations of NSO habitat cluster size (range 4-49 NSO pairs per cluster) and edge-to-edge cluster spacing (range 7-101 km), and an all-habitat landscape. We ran scenarios using empirical estimates of NSO dispersal dynamics and distances and stage class vital rates (representing current population declines) and under adult survival rates adjusted to achieve an initially stationary population. Results suggested that long-term (100-yr) habitat occupancy rates are significantly higher with habitat clusters supporting greater than or equal to 25 NSO pairs and less than or equal to 15 km spacing, and with overall landscapes of greater than or equal to 35-40% habitat. Although habitat provision is key to NSO recovery, no habitat configuration provided for long-term population persistence when coupled with currently observed vital rates. Results also suggested a key role of floaters (unpaired, nonterritorial, dispersing owls) in recolonizing vacant habitat, and that the floater population segment becomes increasingly depleted with greater population declines. We suggest additional areas of modeling research on this and other threatened species.

A BBMM assumes that locations are not independent, whereas the "classical" kernel-density estimator (KDE) assumes they are. We estimated BBMM home ranges for 11 Black Vultures (Coragyps atratus) and 7 Turkey Vultures (Cathartes aura) equipped with satellite transmitters near Marine Corps Air Station Beaufort, South Carolina, from October 2006 to November 2008. The 95% BBMM home ranges (95% BBMM) of the two Black Vultures that traveled >100 km from the capture site were 833 and 2111 km2; of the nine that did not travel as far, 95% BBMM ranged from 33 to 778 km2 and averaged ( plus or minus SE) 243 plus or minus 76 km2. The majority of Turkey Vultures (n = 6) traveled >100 km from the capture site with 95% BBMM ranging from 923 to 7058 km2 and averaging 3173 plus or minus 1109 km2. We also estimated KDE home ranges, using newer satellite technology for comparison with previous studies. Overall 95% KDE ranged from 17 to 16066 km2 for the Black Vulture and 988 to 36257 km2 for the Turkey Vulture. The concept of an animal's home range has evolved over time, as have home-range estimators. With increasing use of satellite telemetry, application of BBMM can greatly enhance our understanding of home ranges, migration routes, seasonal movements, and habitat-use patterns of wild birds over large and often remote areas.

Feline immunodeficiency virus (FIV), and feline leukaemia virus (FeLV) are immunosuppressive viruses of cats that can affect T. gondii oocyst shedding. In this study, the prevalence of antibodies to T. gondii, Bartonella spp., FIV, as well as FeLV antigens were determined in sera from feral cats (Felis catus) from Addis Ababa, Ethiopia. Using the modified agglutination test, IgG antibodies to T. gondii were found in 41 (85.4%) of the 48 cats with titres of 1:25 in one, 1:50 in one, 1:200 in six, 1:400 in six, 1:800 in six, 1:1600 in eight, and 1:3200 in 13 cats. Toxoplasma gondii IgM antibodies were found in 11/46 cats tested by ELISA, suggesting recent infection. Antibodies to Bartonella spp. were found in five (11%) of 46 cats tested. Antibodies to FIV or FeLV antigen were not detected in any of the 41 cats tested. The results indicate a high prevalence of T. gondii and a low prevalence of Bartonella spp. infection in cats in Ethiopia.

We examined effects of fire, defoliation, and interspecific/intraspecific planting for 1) threeawn responses in the presence of threeawn, Bouteloua gracilis, or Pascopyrum smithii, and 2) B. gracilis and P. smithii response with threeawn. Biomass, aboveground production, tillers, and axillary buds were analyzed following two fire and four clipping treatments applied to three species-pair combinations in a completely randomized factorial design with nine replications. Fire killed 36% of threeawn. Fire reduced surviving threeawn biomass 61% and reduced production 27%. Threeawn production was greatest when neither plant was clipped and least when competing species were moderately clipped, or when both plants were severely clipped. Tiller counts of burned threeawn were similar among clipping treatments, and less than non-clipped or moderately clipped plants not burned. Fire decreased threeawn axillary buds on average by 25%. Moderately clipped plants had greater production than those from other clipping treatments across species. Average threeawn percentage of pot biomass was greater with B. gracilis (46 plus or minus 3% SE) than P. smithii (38 plus or minus 3% SE). Fire reduced threeawn from 60 plus or minus 3% to 23 plus or minus 3% of pot biomass, indicating good potential for rapid reductions in threeawn dominance and restoration of plant diversity with fire.

This study used rainfall (0.5 m2 and 13 m2 scales) and concentrated flow simulations and measures of vegetation, ground cover, and soils to investigate hydrologic and erosion impacts of western juniper (Juniperus occidentalis Hook.) encroachment into sagebrush steppe and to evaluate short-term effects of burning and tree cutting on runoff and erosion responses. The overall effects of tree encroachment were a reduction in understory vegetation and formation of highly erodible, bare intercanopy between trees. Runoff and erosion from high-intensity rainfall (102 mm.h-1, 13 m2 plots) were generally low from unburned areas underneath tree canopies (13 mm and 48 g.m-2) and were higher from the unburned intercanopy (43 mm and 272 g.m-2). Intercanopy erosion increased linearly with runoff and exponentially where bare ground exceeded 60%. Erosion from simulated concentrated flow was 15- to 25-fold greater from the unburned intercanopy than unburned tree canopy areas. Severe burning amplified erosion from tree canopy plots by a factor of 20 but had a favorable effect on concentrated flow erosion from the intercanopy. Two years postfire, erosion remained 20-fold greater on burned than unburned tree plots, but concentrated flow erosion from the intercanopy (76% of study area) was reduced by herbaceous recruitment. The results indicate burning may amplify runoff and erosion immediately postfire. However, we infer burning that sustains residual understory cover and stimulates vegetation productivity may provide long-term reduction of soil loss relative to woodland persistence. Simply placing cut-downed trees into the unburned intercanopy had minimal immediate impact on infiltration and soil loss. Results suggest cut-tree treatments should focus on establishing tree debris contact with the soil surface if treatments are expected to reduce short-term soil loss during the postcut understory recruitment period.

The three A. donax genotypes were collected from Laredo, Austin and Balmorhea, TX, which represented the majority of the genotypic diversity found in Texas watersheds. Although R. donacis developed on all three genotypes of the plant, the Austin A. donax genotype, followed by the Laredo genotype, were the most suitable in terms of the size of first-generation immature and adult scale populations that developed after crawler release. Both the Laredo and Austin genotypes of A. donax are likely to be of Spanish origin and are close genetic matches with scale's original host plant genotype in Alicante, Spain. In comparison, survival was lowest on the phylogenetically distant genotype of A. donax from Balmorhea, TX. Although the population size of settled, immature second-generation scales varied in a manner similar to that of the first generation, the fecundity of isolated first-generation females was not significantly different across the three plant genotypes, suggesting that R. donacis is not a genotype specialist in terms of nutrient assimilation for reproduction. Rather, differences in genotype suitability affect rates of success of crawler settling. These results indicate that selection of scale genotype from the native range may have a moderate influence on the success of R. donacis and ultimately the biological control programme.

The infected states are associated with different mtDNA haplotypes and reduced mtDNA variability. The previous results demonstrated that the major mtDNA clades of D. barberi were infected with different variants of Wolbachia; however, the total amount of Wolbachia diversity was substantially underestimated. Here we report sequences of the Wolbachia wsp surface protein gene indicating that multiple infections are present. Analysis of the wsp sequences establishes the existence at least five distinct wsp variants. The recovery frequency of specific wsp hypervariable regions (HVR) obtained from several individuals was unequal. The most common was obtained 33 times, the least common only once. One of the Wolbachia variants was present in both singly infected and multiply infected individuals. A possible explanation for the frequency differences are that the frequency of each variant is not the same within each insect. An alternative possibility is that not all individuals are infected with all five variants and that different animals contain different combinations of the variants. The second scenario suggests that some variants are rare in the population. Comparisons of the wsp genes with sequences in GenBank show that two of the variants are most similar to variants infecting subspecies of the congeneric western corn rootworm (Diabrotica virgifera virgifera LeConte and Diabrotica virgifera zeae Krysan & Smith). Individual wsp HVRs were also aligned with GenBank sequences. The results provide evidence that some HVRs are much more common than others and that the HVRs can be shuffled to create new wsp genes.

AN - 1365053883; 23307847 AB - Alkaloids produced by the fungal endophyte (Neotyphodium coenophialum) that infects tall fescue [Lolium arundinaceum (Schreb.) Darbysh.] are a paradox to cattle production. Although certain alkaloids impart tall fescue with tolerances to environmental stresses, such as moisture, heat, and herbivory, ergot alkaloids produced by the endophyte can induce fescue toxicosis, a malady that adversely affects animal production and physiology. Hardiness and persistence of tall fescue under limited management can be attributed to the endophyte, but the trade-off is reduced cattle production from consumption of ergot alkaloids produced by the endophyte. Improved understanding and knowledge of this endophyte-grass complex has facilitated development of technologies and management systems that can either mitigate or completely alleviate fescue toxicosis. This review discusses the research results that have led to development of 5 management approaches to either reduce the severity of fescue toxicosis or alleviate it altogether. Three approaches manipulate the endophyte-tall fescue complex to reduce or alleviate ergot alkaloids: 1) use of heavy grazing intensities, 2) replacing the toxic endophyte with nonergot alkaloid-producing endophytes, and 3) chemical suppression of seed head emergence. The remaining 2 management options do not affect ergot alkaloid concentrations in fescue tissues but are used 1) to avoid grazing of tall fescue with increased ergot alkaloid concentrations in the late spring and summer by moving cattle to warm-season grass pasture and 2) to dilute dietary alkaloids by interseeding clovers or feeding supplements.

Less is known about the accumulation of other hazardous elements like arsenic (As) and antimony (Sb) in these species. The present paper investigated selected medicinal plants naturally growing on old mining sites in Slovakia, Central Europe, contaminated by As and Sb. Both these elements are nonessential for plants and, in higher level, might be phytotoxic. The soil concentration of As and Sb at three different localities extensively used for mining of Sb ores in former times highly exceed values characteristic for noncontaminated substrates and ranged between 146 and 540 mg kg super(-1) for As and 525 and 4,463 mg kg super(-1) for Sb. Extraction experiments of soils show differences between As and Sb leaching, as the highest amount of mobile As was released in acetic acid while Sb was predominantly released in distilled water. In total, seven different plant species were investigated (Fragaria vesca, Taraxacum officinale, Tussilago farfara, Plantago major, Veronica officinalis, Plantago media, and Primula elatior), and the concentration of investigated elements in shoot ranged between 1 and 519 mg kg super(-1) for As and 10 and 920 mg kg super(-1) for Sb. Differences in the bioaccumulation of As and Sb as well as in the translocation of these elements from root to shoot within the same species growing on different localities have been found. This indicate that efficiency of As and Sb uptake might vary between individual plants of the same species on different sites. Increased bioaccumulation of As and Sb in biomass of investigated plants might be dangerous for human when used for traditional medicinal purposes.

Glycoside hydrolase family 43 is recognized as a source of highly active beta -xylosidases, some of which could have practical applications. The biochemical details of four GH43 beta -xylosidases (those from Alkaliphilus metalliredigens QYMF, Bacillus pumilus, Bacillus subtilis subsp. subtilis str. 168, and Lactobacillus brevis ATCC 367) are examined here. Sedimentation equilibrium experiments indicate that the quaternary states of three of the enzymes are mixtures of monomers and homodimers (B. pumilus) or mixtures of homodimers and homotetramers (B. subtilis and L. brevis). k sub(cat) and k sub(cat)/K sub(m) values of the four enzymes are higher for xylobiose than for xylotriose, suggesting that the enzyme active sites comprise two subsites, as has been demonstrated by the X-ray structures of other GH43 beta -xylosidases. The K sub(i) values for d-glucose (83.3-357 mM) and d-xylose (15.6-70.0 mM) of the four enzymes are moderately high.

Genome sequence databases of Saccharomyces cerevisiae and Candida albicans have provided an overview of this family of genes. Annotation of this gene family in most fungal genomes is still far from perfect and refined bioinformatic algorithms are urgently needed. Aspergillus flavus is a saprophytic soil fungus that can produce the carcinogenic aflatoxin. It is the second leading causative agent of invasive aspergillosis. The 37-Mb genome of A. flavus is predicted to encode 12,000 proteins. Two and a half percent of the total proteins are estimated to contain the C6 domain, more than twofold greater than those estimated for yeast, which is about 1 %. The variability in the spacing between cysteines, C sub(3)-C sub(4) and C sub(5)-C sub(6), in the zinc cluster enables classification of the domains into distinct subgroups, which are also well conserved in Aspergillus nidulans. Sixty-six percent (202/306) of the A. flavus C6 proteins contain a specific transcription factor domain, and 7 % contain a domain of unknown function, DUF3468. Two A. nidulans C6 proteins containing the DUF3468 are involved in asexual conidiation and another two in sexual differentiation. In the anamorphic A. flavus, a homolog of the latter lacks the C6 domain. A. flavus being heterothallic and reproducing mainly through conidiation appears to have lost some components involved in homothallic sexual development. Of the 55 predicted gene clusters thought to be involved in production of secondary metabolites, only about half have a C6-encoding gene in or near the gene clusters. The features revealed by the A. flavus C6 proteins likely are common for other ascomycete fungi.

This study was conducted to investigate the vertical distribution of scab in tall pecan trees (14 to 16 m tall) in three experiments in 2010 and 2011. Although 2010 had average rainfall, a factor that drives scab epidemics, 2011 was a very dry year with a consequently low scab severity. A total of eight trees were included in each experiment, four were nontreated controls, and four were sprayed using a ground-based air-blast sprayer. Trees were assessed for foliar and fruit scab at 0-5.0, 5.0 super(+)-7.5, 7.5 super(+)-10.0, 10.0 super(+)-12.5 and 12.5 super(+)-15.0 m. Mixed model analysis showed main effects of height, fungicide treatment, and height*treatment interactions in all three experiments, although on foliage the effects were less consistent (P value = 0.003-0.8), perhaps due to delayed fungicide applications early in the season. However, fruit of nontreated trees had more severe scab low in the canopy compared to fungicide-treated trees, with a consistent height*treatment interaction (P value = <0.0001-0.04). Most often the severity of scab in the upper canopy was similar in trees on fungicide-treated and nontreated trees, suggesting that fungicide had less impact at heights greater than or equal to 10.0 m compared to <10.0 m in the canopy. There was a consistent reduction in scab severity on foliage and on immature fruit in August due to fungicide treatment at heights less than or equal to 10.0 m. Above 10.0 m, the effect was inconsistent, but late in the season (October), the fungicide-treated trees showed lower scab severity throughout the canopy. A metallic tracer study using cerium (Ce) showed an exponential relationship between quantities of Ce recovered and sample height in the canopy, with the quantity of Ce at greater than or equal to 10 m being statistically equal to background levels. The relationship between scab severity on fruit and sample height in the canopy of nontreated trees was most often described by a negative linear function, but there was no discernible relationship on fungicide-treated trees, as the severity of scab in the lower canopy was most often similar to that in the upper canopy. Gradients in fungicide coverage and scab severity have ramifications for scab management options and potentially for the development of fungicide resistance in F. effusum.

Accurate and reliable disease assessments are needed to ensure that data provide a measure of actual disease intensity. The Horsfall-Barratt (H-B) category scale and its derivatives are commonly used to assess disease. Estimates using the H-B scale were compared with nearest percent estimate (NPEs) for rating disease severity of pecan scab on valves of fruit. Both inexperienced and experienced raters were included in the experiment. Lin's concordance correlation showed that agreement using NPEs was variable ( rho sub(c) = 0.57 to 0.96), whereas estimates of disease severity using the H-B scale had similar agreement among most raters ( rho sub(c) = 0.59 to 0.98). Converted values of NPEs to the H-B midpoints (NPEH-B) also provided a similar range ( rho sub(c) = 0.61 to 0.96). Neither experienced nor inexperienced raters were consistently better using any of the three methods. Bootstrap analysis indicated that, among experienced raters, precision (r) and agreement ( rho sub(c)) were often reduced when using the H-B scale compared with NPEs. There was no consistent effect of converting NPEs to NPEH-B midpoint values compared with actual H-B values. Inter-rater reliability using the H-B scale was never better than NPEs. Bootstrap analysis indicated no difference in the length of time needed to assess disease but regression analysis suggested that raters who were inherently fast in assessing disease with NPEs were often slower when using the H-B scale; conversely, raters who were slow assessing with NPEs were often faster when using the H-B scale. Thus, there appears to be no advantage in accuracy or reliability or reduction in time when inexperienced or experienced raters used a category rating scale to assess pecan scab.

Recent sequence analysis of LNSV demonstrated a close relationship between the coat proteins of LNSV and MPV. To determine the full extent of the relationship between LNSV and MPV, the genomes of three MPV isolates were sequenced and compared with that of LNSV. Sequence analysis demonstrated that genomic nucleotide sequences as well as virus-encoded proteins of the three MPV isolates and LNSV shared 97% or greater identity. A full-length clone of a California LNSV isolate was developed and virus derived from infectious transcripts was used to evaluate host plant reactions under controlled conditions. Symptoms of LNSV matched those described previously for MPV on most of a select series of host plants, although some differences were observed. Collectively, these molecular and biological results demonstrate that LNSV should be classified as MPV within the family Tombusviridae, genus Tombusvirus, and confirm the presence of MPV in North America.

Fusarium mycotoxin levels in whole small-grain spikes are of concern to producers of whole-crop silage, as well as users of straw containing chaff for animal bedding or winter livestock rations. A 2-year field experiment was performed in Kinston, NC to reveal the time course of FHB development. Eight winter wheat cultivars with varying levels of FHB resistance were used in the 2006 experiment, and four of them were used in 2007. Plots were spray-inoculated with Fusarium graminearum macroconidia at mid-anthesis. Four durations of post-anthesis mist were applied: 0, 10, 20, or 30 days. Spike samples were collected and bulked by plot at 15, 25, 35, 45, 55, and 65 days after anthesis (daa); samples were separated into grain, glume, and rachis fractions. Increasing durations of post-anthesis moisture elevated grain DON and reduced the effect of cultivar on DON. presumably by affecting the expression of resistance, in all spike tissues. Fusarium-damaged kernels increased from early kernel-hard to harvest-ripe in both years. Percent infected kernels increased from medium-milk to harvest-ripe. During grain-fill, DON concentrations declined in grain but increased in rachises and glumes, peaking at early kernel-hard, before declining. Higher mean and maximum DON levels were observed in rachises and glumes than in grain. Estimated whole-spike DON peaked at early kernel-hard. In a high-FHB year, whole-plant harvest for forage should be conducted as early as possible. Straw that may be consumed by livestock could contain significant amounts of DON in chaff, and DON can be minimized if straw is sourced from low-symptom crops. Cultivar FHB resistance ratings and disease data should be useful in predicting whole-spike DON levels. Overall, associations between grain DON levels in harvest-ripe and prior samples were stronger the later the prior samples were collected, suggesting limits to the possibility of predicting harvest-ripe grain DON from earlier levels.

Cereal leaf beetle, Oulema melanopus, adult behavioral responses were examined in a Y-tube olfactometer to cis-jasmone induced plant VOC bouquets and to two synthetic blends of VOCs (3 green leaf volatiles (GLVs); 4 terpenes+indole). In both cereals, eight VOCs [(Z)-3-hexanal, (Z)-3-hexanol, (Z)-3-hexanyl acetate, (Z)- beta -ocimene, linalool, beta -caryophyllene, (E)-s-farnesene, and indole] were induced 100- to 1000-fold after cis-jasmone exposure. The degree of induction in both cereals was usually positively and linearly associated with increasing exposure dose and duration. However, VOC emission rate was only similar to 2-fold greater from plants exposed to the highest vs. lowest cis-jasmone exposure doses (1 x 10 super(4) difference) or durations (6-fold difference). Male and female O. melanopus were deterred by both cereal VOC bouquets after plant exposure to the high cis-jasmone dose (1 x 10 super(4) ng mu l super(-1)), while females were also deterred after plant exposure to the low dose (1 ng mu l super(-1)) but attracted to unexposed plant VOC bouquets. Both O. melanopus sexes were repelled by terpene/indole and GLV blends at two concentrations (25 ng.min super(-1); 125 ng.min super(-1)), but attracted to the lowest dose (1 ng.min super(-1)) of a GLV blend. It is possible that the biologically relevant low cis-jasmone dose has ecological activity and potential for inducing field crop VOCs to deter O. melanopus.

In this study, forage sorghum (Sorghum bicolor L. Moench) cropping systems were initiated on a low organic matter soil (<0.9 %) with a history of intensively tilled low-input cotton production in the semiarid Southern High Plains of the U.S. Sorghum cropping systems were evaluated in a split-plot design with sorghum cultivar as the main plot and the combination of irrigation level (non-irrigated and deficit irrigated) and aboveground biomass removal rate (50 % and 100 %) as the split plot. The sorghum cultivars used varied in yield potential and lignin content, which are important features for feedstock-producing crops. Within 1 year, the transition from long-term cotton cropping systems to sorghum biofuel cropping systems resulted in increased soil microbial biomass C (16 %) and N (17 %) and shifts in the microbial community composition as indicated by differences in fatty acid methyl ester (FAME) profiles. Additionally, enzyme activities targeting C, N, P and S cycles increased 15-75 % (depending on the enzyme) after two growing seasons. Increased enzyme activities (16-19 %) and differences in FAME profiles were seen due to irrigation regardless of aboveground biomass removal rate. Biomass removal rate and the cultivar type had little effect on the soil microbial properties during the time frame of this study. Early results from this study suggest improvements in soil quality and the sustainability of sorghum biofuel cropping for low organic matter agricultural soils.

From dissections, it is believed that all female third-instar larvae, pupae and adult female flies carry nematodes internally, while male adults and larvae do not. This observation of sex-limited association was tested using a molecular diagnostic approach. Nematode-specific primers were used for polymerase chain reaction amplification of a portion of the mitochondrial cytochrome oxidase I gene in order to screen DNA extractions from flies for the presence of nematode DNA. Consistent with evidence from dissections, nearly all extractions from adult female flies were positive for nematode DNA, while all DNA extractions from adult male flies were negative. Nearly half of late-instar larvae screened showed evidence of nematode DNA, consistent with the hypothesis that nematodes are only present within females. This paper is the first to use a molecular method to confirm this phenomenon within the Fergusonina/Fergusobia system.

Linville Gorge Wilderness (LGW) is one example of a high elevation wilderness in the southern Appalachian region that has been subject to stress complexes including chronic acidic deposition and several wildfires, varying in intensity and extent. Soils in LGW are inherently acidic with low base cation concentrations and decades of acidic deposition have contributed to low pH, based saturation, and Ca:Al ratio. We hypothesized that wildfires that occurred in LGW followed by liming burned areas would accelerate the restoration of acidic, nutrient depleted soils. Because soils at LGW had extremely low concentrations of exchangeable Ca super(2+) and Mg super(2+) dolomitic lime was applied to further boost these cations. We evaluated the effectiveness of dolomitic lime application in restoring exchangeable Ca super(2+) and Mg super(2+) and subsequently increasing pH and Ca:Al ratio of soils and making Ca and Mg available to recovering vegetation. Methods: Five treatment areas were established: severely burned twice (2000 & 2007) with dolomitic lime application (2xSBL); moderately burned twice with lime application (2xMBL); severely burned twice, unlimed (2xSB); moderately burned once (2000), unlimed (1xMB); and a reference area (REF; unburned, unlimed). In 2008 and 2009, we measured overstory, understory, and ground-layer vegetation; forest floor mass and nutrients; and soil and soil solution chemistry within each treatment area. Results: All wildfire burned sites experienced substantial overstory mortality. However, understory biomass doubled between sample years on the most recently burned sites due to the rapid regrowth of ericaceous shrubs and prolific sprouting of deciduous trees. Burning followed by lime application (2xSBL and 2xMBL) significantly increased shallow soil solution NO sub(3)-N, but we found no soil solution NO sub(3)-N response to burning alone (2xSB and 1xMB). Surface soil base saturation and exchangeable Ca super(2+) were significantly affected by liming; Ca super(2+) concentrations were greater on 2xMBL and 2xSBL than 2xSB, 1xMB and REF. There was a smaller difference due to moderate burning along with greater soil Ca super(2+) on 1xMB compared to REF, but no difference between 2xSB and REF. Surface and subsurface soil exchangeable Al super(3+) were lower on 2xSBL than 2xSB, 2xMBL, 1xMB, and REF. Liming decreased soil acidity somewhat as surface soil pH was higher on the two burned sites with lime (pH=3.8) compared to 2xSB without lime (pH=3.6). Conclusions: Liming resulted in decreased soil Al super(3+) on 2xSBL coupled with increased soil Ca super(2+) on both 2xSBL and 2xMBL, which improved soil Ca/Al ratios. However, the soil Ca/Al ratio response was transitory, as exchangeable Al super(3+) increased and Ca/Al ratio decreased over time. Higher lime application rates may be necessary to obtain a substantial and longer-term improvement of cation-depleted soils at LGW.

Nisin is the only bacteriocin that can be used as a food preservative. Due to its antimicrobial activity, it can be used to control L. monocytogenes in food; however, the antimicrobial mechanism of nisin activity against L. monocytogenes is not fully understood. The CtsR (class III stress gene repressor) protein negatively regulates the expression of class III heat shock genes. A spontaneous pressure-tolerant ctsR deletion mutant that showed increased sensitivity to nisin has been identified. Microarray technology was used to monitor the gene expression profiles of the ctsR mutant under treatments with nisin. Compared to the nisin-treated wild type, 113 genes were up-regulated (>2-fold increase) in the ctsR deletion mutant whereas four genes were down-regulated (<-2-fold decrease). The up-regulated genes included genes that encode for ribosomal proteins, membrane proteins, cold-shock domain proteins, translation initiation and elongation factors, cell division, an ATP-dependent ClpC protease, a putative accessory gene regulator protein D, transport and binding proteins, a beta-glucoside-specific phosphotransferase system IIABC component, as well as hypothetical proteins. The down-regulated genes consisted of genes that encode for virulence, a transcriptional regulator, a stress protein, and a hypothetical protein. The gene expression changes determined by microarray assays were confirmed by quantitative real-time PCR analyses. Moreover, an in-frame deletion mutant for one of the induced genes (LMOf2365_1877) was constructed in the wild-type L. monocytogenes F2365 background. Delta LMOf2365_1877 had increased nisin sensitivity compared to the wild-type strain. This study enhances our understanding of how nisin interacts with the ctsR gene product in L. monocytogenes and may contribute to the understanding of the antibacterial mechanisms of nisin.

Lactate was fermented at up to 210-mM concentration to yield acetic, propionic, butyric, and valeric acids. The bacterium was able to grow at much higher concentrations of d-glucose (500 mM), but never removed more than 80 mM of glucose from the medium, and nearly 60 % the glucose removed was sequestered as intracellular glycogen, with low yields of even-carbon acids (acetate, butyrate, caproate). In the presence of both substrates, glucose was not used until lactate was nearly exhausted, even by cells pregrown on glucose. Glucose-grown cultures maintained only low extracellular concentrations of acetate, and addition of exogenous acetate increased yields of butyrate, but not caproate. By contrast, exogenous acetate had little effect on lactate fermentation. At pH 6.6, growth rate was halved by exogenous addition of 60 mM propionate, 69 mM butyrate, 44 mM valerate, or 33 mM caproate; at pH 5.9, these values were reduced to 49, 49, 18, and 22 mM, respectively. The results are consistent with this species' role as an effective ruminal lactate consumer and suggest that this organism may be useful for industrial production of volatile fatty acids from lactate if product tolerance could be improved. The poor fermentation of glucose and sensitivity to caproate suggests that this strain is not practical for industrial caproate production.

We examined small, fishless headwater streams to determine whether transport of macroinvertebrates into the littoral zone of an oligotrophic lake augmented food availability for Cottus asper, an abundant predatory fish in our study system. We sampled fish and macroinvertebrates during the recruitment and growth season of 2years, either monthly (2004) or bi-monthly (2005), to observe whether stream inputs increased prey availability and whether variation in total macroinvertebrate biomass was tracked by fish. 2. Observations from eight headwater streams indicated that streams did not increase the total macroinvertebrate biomass in the shallow littoral zone at stream inflows, relative to adjacent plots without stream inputs (controls). The taxonomic composition of stream macroinvertebrates drifting toward the lake differed from that in the littoral lake benthos itself, although there was no evidence of any species change in the composition of the littoral benthos brought about by stream inputs. 3. Although streams made no measurable contribution to the biomass or taxonomic composition of the littoral macroinvertebrate benthos, there was substantial temporal variation in biomass among the eight sites for each of the (n=7) sample periods during which observations were made. Variation in total biomass was primarily a function of bottom slope and benthic substrata in the lake habitats. Dominant taxonomic groups were Baetidae, Ephemerellidae (two genera), Leptophlebiidae, Chironomidae (three subfamilies) and Perlodidae, although we did not determine the specific substratum affinities of each taxon. 4. Mixed effects linear models identified a significant interaction between macroinvertebrate biomass and plot type (stream inflow vs. control) associated with fish abundance. Across the observed range of macroinvertebrate biomass, fish showed a significant preference for stream inflows, but more closely tracked food availability in the controls. For young-of-the-year (YOY), a negative effect of temperature was also included in the model, and we observed lower temperatures at stream inflows. However, abundance of predatory adults affected habitat selection for YOY. Lake-bottom slope also accounted for variation in abundance in both fish models. 5. Our results suggest that the effect of fishless headwater streams on downstream fish may not always be through direct delivery of food. In this study system, fish preferred stream inflow plots, but this preference interacted with macroinvertebrate biomass in a manner that was difficult to explain. For YOY, predation risk was related to the preference for stream inflows, although the specific factor that mitigates predation risk remains poorly understood.

An environmentally benign "green," inexpensive way to meet this regulation is to use a low-cost flame-retardant barrier fabric. In this study, a nonwoven fabric of grey unbleached cotton was treated with a low-cost phosphate-based formulation. The energy-dispersive X-ray microanalysis showed uniform nitrogen and phosphorus distribution. With 17% add-on, the flame-retardant unbleached cotton barrier showed a limiting oxygen index of 33% oxygen and 83 mm of char length with no after-flame and no afterglow in the vertical flame test. Under air and nitrogen at 500 degree C, 24% and 35% char remained after thermogravimetric analyses, respectively. This flame resistance is comparable to that of current commercial barrier fabrics made from bleached cotton and Flovan cyanoguanidine or from T-bond grey cotton fiber highlofts (Jones Fiber). Mattresses constructed with a flame-retardant cotton nonwoven barrier fabric are predicted to meet the requirements of 16CFR1633. As a follow-up to this study, a full-scale mattress burn test is recommended.

Some factors linked to the distribution of introduced species include fragmentation and disturbance, native species richness, and climatic and physical conditions of the landscape. However, there are few data sources that enable the assessment of introduced species occupancy in native plant communities over broad regions. Vegetation data from 1,302 forest inventory plots across 24 states in northeastern and mid-western USA were used to examine and compare the distribution of introduced species in relation to forest fragmentation across ecological provinces and forest types, and to examine correlations between native and introduced species richness. There were 305 introduced species recorded, and 66 % of all forested plots had at least one introduced species. Forest edge plots had higher constancy and occupancy of introduced species than intact forest plots, but the differences varied significantly among ecological provinces and, to a lesser degree, forest types. Weak but significant positive correlations between native and introduced species richness were observed most often in intact forests. Rosa multiflora was the most common introduced species recorded across the region, but Hieracium aurantiacum and Epipactus helleborine were dominant in some ecological provinces. Identifying regions and forest types with high and low constancies and occupation by introduced species can help target forest stands where management actions will be the most effective. Identifying seemingly benign introduced species that are more prevalent than realized will help focus attention on newly emerging invasives.

Management of this imperiled taxon requires accurate information on its demography and vital rates. We developed noninvasive survey methods, using hair snares to sample DNA and to estimate abundance and survival at two sites, Kinney Beach and Alder Creek, within Manchester State Park. We extracted DNA and genotyped 371 hair samples resulting in the identification of a total of 54 individuals during annual sampling from 2006-2009. Estimated population numbers were small, ranging from 9-18 individuals at Kinney Beach and 14-18 individuals at Alder Creek. Neither location demonstrated a trend in abundance over the 4-year sample period. There was weak support (evidence ratio 2.15) for higher apparent survival probabilities at Alder Creek (0.75) than Kinney Beach (0.59) and no support for time or site effects on recruitment. Recruitment ranged from 0.25 to 0.46 and was highest during the same interval (2007-2008) at both locations. The time series of estimates from 2006-2009 does not suggest that abundance at either study site is declining; while reassuring, concern still remains due to low total numbers at this, one of the few protected sites for this endangered subspecies.

This study characterized shallow groundwater quality for pre- and post-CW and CP system conditions using data from monitoring wells. Results showed that the average concentrations of groundwater phosphorus (P) decreased from pre-CW to post-CW but increased from pre-CP to post-CP. The average concentrations of groundwater total Kjeldahl nitrogen and ammonium ( NH super(+) sub(4) increased from pre-CW (or CP) to post-CW (or CP), whereas the average concentrations of groundwater arsenic (As), chromium, nickel, and zinc (Zn) decreased from pre-CW to post-CW regardless of the well locations. Variations of groundwater cadmium, copper, and Zn concentrations were larger in pre-CP than in post-CP and had a tendency to decrease from pre-CP to post-CP. In general, the average concentrations of groundwater aluminum and manganese decreased and of groundwater calcium, iron, magnesium, and sodium increased from pre-CP to post-CP. The average values of water levels (depth from the ground surface), redox potential, and conductance decreased and of chloride and sulfate (SO super(-)2 sub(4)) increased after the wetland and pond were constructed regardless of the well locations. Results further revealed that there were significant differences ( alpha =0.05) between the pre- and post-CW (or CP) for redox potential, water level, and As. This study suggests that the CW-CP system had discernible effects on some of the shallow groundwater quality constituents. This information is very useful for fully estimating overall performance of stormwater treatment with the CW-CP system.

Identifying items in stomachs of introduced rodents helps determine rodents' trophic positions and species most at risk of consumption. In the Hawaiian Islands, which lacked rodents prior to human arrival, three rodents (Rattus rattus or black rat, R. exulans or Pacific rat, Mus musculus or house mouse) commonly coexist in native habitats where they consume a wide range of plants and animals. These three rodent species were trapped in montane forest for 2.5 years; their stomach contents were analyzed to determine short-term diets (n = 12-95 indiv. per species), and isotopic fractions of delta super(15)N and delta super(13)C in their bone collagen were analyzed to further estimate their trophic positions (n = 11-20 indiv. per species). For all three species, >75 % of individuals had plants and >90 % had arthropods in their stomachs, and significant differences in mean relative abundances were found for food items in stomachs among all three rodents. Rodents may be dispersing some native and non-native seeds, including the highly invasive Clidemia hirta. Most identifiable arthropods in rodent stomachs were non-native, and no stomachs contained birds, snails, or lizards. The delta super(15)N and delta super(13)C signatures were consistent with trophic feeding differences revealed from stomach contents. Dietary niche differentiation by coexisting rodent species is evident in this forest, with Pacific rats being intermediate between the mostly carnivorous house mouse and the mostly herbivorous black rat; such findings can help forecast rodent impacts and direct management efforts in ecosystems where these invasive animals coexist.

Citrobacter rodentium is a mouse pathogen that mimics many aspects of enterohemorrhagic Escherichia coli infection of humans and serves as a useful model for studying virulence mechanisms. Emergence of a hyperinfectious state after passage through mouse gastrointestinal tract was reported for C. rodentium. We wanted to investigate if increased acid tolerance could explain hypervirulence status of C. rodentium. Although we were able to observe hyperinfectious state of C. rodentium upon host passage, the cells were extremely acid sensitive. Growth under mildly acidic conditions (LB-MES, pH 5.5) induced acid tolerance of C. rodentium, but did not improve the organism's ability to establish infection. Growth under anaerobic environment on fecal components also did not induce hyperinfectious state. Thus, contrary to conventional anticipation, hypervirulent C. rodentium cells were found to be acid sensitive thereby revealing limitations of the role of mouse gastric acidity by itself in elucidating the hypervirulent phenotype.

Microorganisms from environmental sources in different geographic regions of Thailand were tested for antibacterial activity against LAB. Four bacterial strains, designated as ALT3A, ALT3B, ALT17, and MR1, produced inhibitory effects on growth of LAB. Sequencing of rRNA identified these strains as species of Bacillus subtilis (ALT3A and ALT3B) and B. cereus (ALT17 and MR1). Cell mass from colonies and agar samples from inhibition zones were analyzed by matrix-assisted laser desorption/ionization-time of flight mass spectrometry. The spectra of ALT3A and ALT3B showed a strong signal at m/z 1,060, similar in mass to the surfactin family of antimicrobial lipopeptides. ALT3A and ALT3B were analyzed by zymogram analysis using SDS-PAGE gels placed on agar plates inoculated with LAB. Cell lysates possessed an inhibitory protein of less than 10 kDa, consistent with the production of an antibacterial lipopeptide. Mass spectra of ALT17 and MR1 had notable signals at m/z 908 and 930 in the whole cell extracts and at m/z 687 in agar, but these masses do not correlate with those of previously reported antibacterial lipopeptides, and no antibacterial activity was detected by zymogram. The antibacterial activities produced by these strains may have application in the fuel ethanol industry as an alternative to antibiotics for prevention and control of bacterial contamination.

AN - 1347256662; 22917841 AB - An increase in the aggregation of misfolded/damaged polyubiquitinated proteins has been the hallmark of many age-related neurodegenerative diseases. The accumulation of these potentially toxic proteins in brain increases with age, in part due to increased oxidative and inflammatory stresses. Walnuts, rich in omega fatty acids, have been shown to improve memory, cognition and neuronal effects related to oxidative stress (OS) and inflammation (INF) in animals and human trials. The current study found that feeding 19-month-old rats with a 6% or 9% walnut diet significantly reduced the aggregation of polyubiquitinated proteins and activated autophagy, a neuronal housekeeping function, in the striatum and hippocampus. Walnut-fed animals exhibited up-regulation of autophagy through inhibiting phosphorylation of mTOR, up-regulating ATG7 and Beclin 1, and turnover of MAP1BLC3 proteins. The clearance of polyubiquitinated protein aggregates such as p62/SQSTM1 was more profound in hippocampus, a critical region in the brain involved in memory and cognitive performance, than striatum. The clearance of ubiquitinated aggregates was in tandem with significant reductions in OS/INF, as indicated by the levels of P38-MAP kinase and phosphorylations of nuclear factor kappa B and cyclic AMP response element binding protein. The results demonstrate the effectiveness of a walnut-supplemented diet in activating the autophagy function in brain beyond its traditionally known antioxidant and anti-inflammatory benefits.

AN - 1328546333; 23070903 AB - A livestock poisoning outbreak near Kingman, Arizona, USA, potentially linked to dehydropyrrolizidine alkaloids, prompted an evaluation of some local plants for the presence of these hepatotoxic alkaloids. To qualitatively and quantitatively examine two species of Cryptantha, a Boraginaceous genus previously shown to produce potentially toxic pyrrolizidine alkaloids, collected from the vicinity of Kingman, Arizona. Plant extracts were analysed using HPLC-electrospray ionisation (+)-MS and MS/MS to determine the presence of dehydropyrrolizidine alkaloid esters. Identities were confirmed by comparison of chromatographic and MS data with authenticated standards and, in the case of the previously undescribed alkaloids, using one- and two-dimensional NMR spectroscopy and high-resolution mass measurement. Cryptantha inequata and C. utahensis were shown to produce retronecine-based dehydropyrrolizidine alkaloids at approximately 0.05% and 0.09% w/w respectively. Cryptantha inequata produced mainly echimidine, acetylechimidine and echiuplatine; dehydropyrrolizidine alkaloids that were previously associated with Echium plantagineum. The previously undescribed structure of echiuplatine was elucidated as an amphoteric, open chain diester with angelic acid and 3-hydroxy-3-methylglutaric acid. Along with lycopsamine, intermedine and dihydroxyechiumine, C. utahensis produced cryptanthine, a previously undescribed open chain diester alkaloid esterified with angelic acid and 2,3-dihydroxy-2-methylbutanoic acid. All pyrrolizidine alkaloids detected were present in the plants mainly as their N-oxides. The retronecine-based alkaloids detected in both Cryptantha species herein investigated aligns them within the Krynitzkia subgenus. The dehydropyrrolizidine alkaloids detected are expected to be toxic but the low levels in the plants potentially mitigate the risk. The identification of the amphoteric echiuplatine provides a cautionary note with respect to the analysis of total dehydropyrrolizidine alkaloid content. Published 2012.

The normalized concentration in breakthrough curves (BTCs) of AgNPs increased with a decrease in solution ionic strength (IS), and an increase in water velocity, sand grain size, and input concentration (Co). In contrast to conventional filtration theory, retention profiles (RPs) for AgNPs exhibited uniform, nonmonotonic, or hyperexponential shapes that were sensitive to physicochemical conditions. The experimental BTCs and RPs with uniform or hyperexponential shape were well described using a numerical model that considers time- and depth-dependent retention. The simulated maximum retained concentration on the solid phase (Smax) and the retention rate coefficient (k1) increased with IS and as the grain size and/or Co decreased. The RPs were more hyperexponential in finer textured sand and at lower Co because of their higher values of Smax. Conversely, RPs were nonmonotonic or uniform at higher Co and in coarser sand that had lower values of Smax, and tended to exhibit higher peak concentrations in the RPs at lower velocities and at higher solution IS. These observations indicate that uniform and nonmonotonic RPs occurred under conditions when Smax was approaching filled conditions. Nonmonotonic RPs had peak concentrations at greater distances in the presence of excess amounts of surfactant, suggesting that competition between AgNPs and surfactant diminished Smax close to the column inlet. The sensitivity of the nonmonotonic RPs to IS and velocity in coarser textured sand indicates that AgNPs were partially interacting in a secondary minimum. However, elimination of the secondary minimum only produced recovery of a small portion (<10%) of the retained AgNPs. These results imply that AgNPs were largely irreversibly interacting in a primary minimum associated with microscopic heterogeneity.

Fresh-cut cantaloupe samples, inoculated with three main serotypes (1/2a, 1/2b, and 4b) of L. monocytogenes, were incubated at different temperatures, ranging from 4 to 43 degree C, to develop kinetic growth models. During storage studies, the population of both background microorganisms and L. monocytogenes began to increase almost immediately, with little or no lag phase for most growth curves. All growth curves, except for two growth curves of L. monocytogenes 1/2a at 4 degree C, developed to full curves (containing exponential and stationary phases), and can be described by a 3-parameter logistic model. There was no significant difference (P = 0.28) in the growth behaviors and the specific growth rates of three different serotypes of L. monocytogenes inoculated to fresh-cut cantaloupe. The effect of temperature on the growth of L. monocytogenes and spoilage microorganisms was evaluated using three secondary models. For L. monocytogenes, the minimum and maximum growth temperatures were estimated by both the Ratkowsky square-root and Cardinal parameter models, and the optimum temperature and the optimum specific growth rate by the Cardinal parameter model. An Arrhenius-type model provided more accurate estimation of the specific growth rate of L. monocytogenes at temperatures <4 degree C.

Based on panel estimation methods, and using both a moving SD measure and the Perée and Steinherr (1989) measure of exchange rate uncertainty, the results show that US bilateral fresh fruit trade has been negatively affected by exchange rate uncertainty. We also find some evidence that the exchange rate between the US dollar and the currencies of Latin American trading partners accounts for most of the negative impact of exchange rate uncertainty on bilateral trade flows in fresh fruit. In contrast, when using panel estimation methods and both measures of exchange rate uncertainty, we find no statistically significant evidence for any negative effect of exchange rate uncertainty on US bilateral fresh vegetable trade. However, we do find a statistically significant negative effect for exchange rate uncertainty when we estimate a US export gravity equation for fresh vegetables using the same panel of countries.

We compared methods of evaluating such responses to identify tetanus toxoid- (TT) specific Th1, Th2, Th17 and IL10+ cells. Eight healthy subjects were given a TT booster vaccination. Blood was drawn before, 3, 7, 14, and 28days after vaccination and peripheral blood mononuclear cells (PBMC) were cultured for 7days with TT, negative control (diluent), and a positive control (Staphylococcus enterotoxin B [SEB]). Activation markers (CD25 and CD69) were measured after 44h (n=8), cytokines in supernatant after 3 and 7days, and intracellular cytokine staining (ICS) of proliferated cells (identified by dye dilution) after 7days (n=6). Vaccination increased TT-specific expression of CD25 and CD69 on CD3+CD4+ lymphocytes, and TT-specific proliferation at 7, 14 and 28days post vaccination. Vaccination induced TT-specific Th1 (IFN- gamma , TNF- alpha , and IL-2) Th2 (IL-13, IL-5, and IL-4), Th17 (IL-17A) and IL-10+ cells as measured by ICS. TT-specific Th1 cells were the most abundant (12-15% of all TT-specific CD4+ T-cells) while IL10+ (1.8%) Th17 (1.1%) and Th2 cells (0.2-0.6%) were less abundant. TT-specific cytokine concentrations in PBMC supernatants followed the same pattern where a TT-specific IL-9 response was also seen. In conclusion, TT booster vaccination induced a broad T-helper cell response. This method of evaluating cytokine phenotypes may be useful in examining the impact of nutrition and environmental conditions on the plasticity of T-helper cell memory responses.

All bacteria used in this study were able to develop high resistance to gossypol. However, only some bacteria were able to develop resistance to proflavine hemisulfate, novobiocin, or ciprofloxacin. When the virulence of resistant bacteria was tested in tilapia or catfish, none of the gossypol-resistant isolate was attenuated, whereas majority of the proflavine hemisulfate-resistant isolates were attenuated. However, all proflavine hemisulfate-attenuated bacteria failed to provide significant protection to fish. Eight novobiocin- or ciprofloxacin-resistant Gram-positive bacteria (S. agalactiae and S. inaie) were found to be attenuated. However, none of them offered protection higher than 70%. Of seven attenuated novobiocin-or ciprofloxacin-resistant Gram-negative isolates (A. hydrophila and E. tarda), only one (novobiocin-resistant E. tarda 30305) was found to safe and highly efficacious. When E. tarda 30305-novo vaccinated Nile tilapia were challenged by its virulent E. tarda 30305, relative percent of survival of vaccinated fish at 14- and 28-days post vaccination (dpv) was 100% and 92%, respectively. Similarly, E. tarda 30305-novo offered 100% protection to channel catfish against challenges with virulent parent isolate E. tarda 30305 at both 14- and 28-dpv. Our results suggest that the development of live attenuated bacterial vaccines that are safe and efficacious is challenging, although it is feasible.

The corn was grown within a randomized, complete block study that included both a 2-year (corn-soybean) rotation and a 4-year (corn-field peas-winter wheat-soybean) rotation with plots containing the corn phase present in every year, 2007-2010. Annual carbon dioxide (CO sub(2)) fluxes were between 1500 and 4000 kg CO sub(2)-C ha super(-1) during the four-year study. Annual nitrous oxide (N sub(2)O) fluxes ranged from 0.8 to 1.5 kg N sub(2)O-N ha super(-1) with peak fluxes during spring thaw and following fertilization. Net methane (CH sub(4)) fluxes in 2007 were close to zero, while fluxes for 2008-2010 were between 0.9 and 1.6 kg CH sub(4)-C ha super(-1). Methane fluxes increased with consistently escalating values of soil moisture over the four-year period demonstrating that soils which previously exhibited neutral or negative CH sub(4) flux may become net CH sub(4) producers in response to multiyear climatic trends. No significant differences in gas fluxes from corn due to treatment (2-year vs. 4-year rotation) were observed. Mean net annual soil surface gas fluxes from corn calculated over four years for both treatments were 2.4 Mg CO sub(2)-C ha super(-1), 1.2 kg N sub(2)O-N ha super(-1), and 0.9 kg CH sub(4)-C ha super(-1). Annual global warming potentials (GWP) as CO sub(2) equivalents were 572 kg ha-1 and 30 kg ha super(-1) for N sub(2)O and CH sub(4), respectively. Measurements of soil carbon showed that the 4-yr rotation accrued 596 kg C ha super(-1) yr super(-1) in the top 30 cm of soil which would be more than sufficient (2.19 Mg CO sub(2) eq ha super(-1) yr super(-1)) to offset the annual GWP of the nitrous and methane emissions from corn. In contrast, the 2-year rotation lost 120 kg C ha super(-1) yr super(-1) from the top 30 cm of soil resulting in corn being a net producer of greenhouse gases and associated GWP.

AN - 1326729185; 23453818 AB - Irgarol 1051 is a common antifouling biocide and is highly toxic to non-target plant species at low ng/L concentrations. We measured up to 254 ng/L Irgarol in water and up to 9 ng/g dry weight Irgarol in sediments from Southern California recreational marinas. Irgarol's metabolite, M1, concentrations were up to 62 ng/L in water and 5 ng/g dry weight in sediments. Another antifouling biocide, diuron, reached up to 68 ng/L in water and 4 ng/g dry weight in sediments. The maximum Irgarol concentrations in water were greater than the Irgarol concentration recommended as the plant toxicity benchmark (136 ng/L), suggesting that Irgarol concentrations may be high enough to cause changes in phytoplankton communities in the sampled marinas. Irgarol concentrations measured in sediments were greater than calculated Environmental Risk Limits (ERLs) for Irgarol in sediments (1.4 ng/g). Antifouling pesticide accumulation in sediments may present a potential undetermined risk for benthic organisms. Published by Elsevier Ltd.

The project was initiated in response to mega-fires and the need for managers to have consistent, wall-to-wall (i.e., all wildlands regardless of agency/ownership), geospatial data, on vegetation, fuels, and terrain to support use of fire behavior and effects prediction systems in guiding policy and management decisions. Base layers were created in a 5-year program of research and development ending in 2009, with processes in place to periodically update fuel and vegetation layers in response to anthropogenic and natural disturbances. LANDFIRE has been institutionalized as the primary data source for modeling activities aimed at meeting the goals of the United States' National Cohesive Wildland Fire Management Strategy, and the data are available on-line to any user for conducting landscape analyses. Data access and use are high and expected to grow with the increasing scope and complexity of wildland fire management, thus requiring continued LANDFIRE improvements and updates.

For a number of years, these extraordinary wildfires have been increasing in number and in severity. They affect countries around the world, including those with enormous firefighting capabilities. High-impact mega-fires are frustrating efforts to provide for public safety, slow rates of deforestation, sequester carbon and reduce black carbon emissions. Despite more determined bidding, attempts to match increasing wildfire threats with greater suppression force have not stemmed climbing mega-fire trends. Yet, the majority of after-action reviews, reports, and commissions continue to weight recommendations to correcting emergency response deficiencies, generally through a fire operations lens. This paper explores the mega-fire phenomenon through a forest land management prism. It is an early attempt to focus on the contributory factors that may set the stage for high-impact mega-fires. The paper draws on the results from two coarse-filter overviews of high-impact mega-fires from around the world and the authors' firsthand experiences dealing with others in the United States. Drought and fire exclusion policies have been implicated in the large fire problem. However, several high-impact mega-fires can be further traced to land management decisions that resulted in dense forest conditions with high biomass and fuel build-ups over extensive areas. As droughts have intensified, more of these accumulated fuels have become available to burn at intensities that exceed suppression capabilities. In contrast, some places have managed to largely avoid high-impact mega-fires. State and federal lands in Florida and Crown lands in Western Australia have better aligned policies and practices with the disturbance regimes that define the forested landscapes that they protect. They use prescribed fire at appropriate intensities, intervals, and scales to reduce fuels as the means to protect people, maintain forest resilience, ensure biodiversity, and increase margins of suppression effectiveness. Forest land management policies and practices that, by design or by default, result in greater volumes of fuel and rely on suppression capabilities to maintain these conditions may no longer be sustainable as droughts deepen and become more widespread. This paper suggests that adapting wildland fire management programs, forest land management policies, and the current regulatory framework to the reality of warmer, drier climate patterns will be essential in reducing mega-fire risks. Protecting fire-prone landscapes can no longer rely on suppression alone; protection will become more dependent on the management of forests where high-impact mega-fires incubate.

Bacterial cold water disease (BCWD) is one of the most frequent causes of elevated mortality in juvenile salmonids, and we have selectively bred three genetic lines of rainbow trout for varying resistance to BCWD. These lines, designated ARS-Fp-R (resistant), ARS-Fp-C (control) and ARS-Fp-S (susceptible), differ in survival following standardized laboratory challenges with the causative agent of BCWD, Flavobacterium psychrophilum. This study evaluated survival of the genetic lines in laboratory challenges and in a production environment. Evaluations of disease resistance demonstrated a reproducible, 30% or greater, survival difference between ARS-Fp-R and ARS-Fp-S lines at body weights ranging from 0.7 to 13g. Farm trials were performed to evaluate survival over an 80-day growth period starting after the trout began feeding. After a BCWD epizootic, the ARS-Fp-R line displayed significantly greater risk-adjusted survival (95.7%) than the ARS-Fp-S line (91.2%, P<0.0001) and the ARS-Fp-C line (92.4%, P<0.0001). Phenotype stability in farm-trial fish was also evaluated using laboratory challenges. The ARS-Fp-R line consistently displayed a higher, but not always statistically significant, survival percentage compared to the other lines and the data suggest that the magnitude of the survival phenotype difference is sensitive to environmental influence. In summary, the overall greater survival of the ARS-Fp-R line provides evidence of genetic improvement under production conditions.

Recent studies have also highlighted the potential value of protein intakes in excess of present recommendations. The roles that leisure-time physical activity and protein quality play in the preservation of skeletal muscle during ageing, and how such influences interact in free-living people are unclear. We sought to clarify these issues using data collected on 2425 participants aged greater than or equal to 50 years in the US National Health and Nutrition Examination Survey (2003-2006). We estimated subjects' usual intakes of total protein and beef from two 24 h diet recalls and computed the appendicular skeletal muscle mass index from anthropometric measures. Participants self-reported their physical activity levels. Analyses accounted for demographic factors and smoking. The association between muscle-strengthening activity and the appendicular skeletal muscle mass index varied with protein intake. Furthermore, among obese subjects with protein intakes < 70 g/d, those who performed such activities had a lower appendicular skeletal muscle mass index than those who were physically inactive. Protein intakes above the present recommendations were associated with benefits to obese subjects only. The appendicular skeletal muscle mass index of non-obese subjects who performed vigorous aerobic activities was consistently high; in obese subjects, it varied with protein intake. High-protein intake was associated with a modest increase in the appendicular skeletal muscle mass index in non-obese, physically inactive subjects. The present findings reinforce the idea that muscle-strengthening exercise preserves muscle when combined with adequate dietary protein. Vigorous aerobic activity may also help.

Recent studies have suggested that sonic anemometers with non-orthogonal transducers can underestimate vertical wind velocity (w) and sensible heat flux (H) when compared to orthogonal designs. In this study we tested whether a non-orthogonal sonic anemometer (CSAT3, Campbell Scientific, Inc.) measures lower w and H than an orthogonal sonic anemometer (SATI/3Vx, Applied Technologies, Inc.) and through experimental manipulation we tested if this difference can be attributed to errors in the CSAT3. Four CSAT3s and one SATI/3Vx were mounted symmetrically in a horizontal array on top of the Glacier Lakes Ecosystem Experiments Site (GLEES) AmeriFlux scaffold (southeastern Wyoming, USA) and in close enough proximity to allow covariance measurements between neighboring sonic anemometers. The CSAT3s were paired and measurements of the three orthogonal wind velocities (u, v, and w) were tested by alternatively rotating each sonic anemometer 90 degree around its u-axis, essentially forcing the sonic v-axis transducer system to measure w. Analysis was performed on data corresponding to gusts of wind located within the 15 degree cone defined around the u-axis to ensure operation within manufacturer specifications. We found that the CSAT3 measured 8% lower H than the SATI/3Vx and that was associated with a 6-12% lower measurement of w. From the CSAT3 manipulations we found w was underestimated by 6-10% which led directly to an 8-12% underestimate of the kinematic heat flux, the fundamental covariance of H. These results have implications for ecosystem flux research and the energy imbalance problem considering the prevalence of the CSAT3 and the non-orthogonal sonic anemometer design.

Mobility was recorded over a 2 h period using ethological tracking software. Mortality was recorded immediately after horizontal mobility experiments and 24 h later. RESULTS Esfenvalerate had the greatest impact on mobility. Immediately after exposure to this compound, plum curculios moved significantly greater distances and for a significantly longer period of time compared with all other compounds. After 24 h, esfenvalerate also led to high mortality rates (>86.0%). Exposure to azinphosmethyl and phosmet also led to high rates of mortality, although the impact on mobility was less pronounced. Exposure to indoxacarb, thiacloprid, imidacloprid, novaluron, myclobutanin and mancozeb had no impact on mobility and resulted in little to no mortality. Clothianidin affected mobility after a 2 h exposure period, and high mortality (60%) was recorded after 24 h. CONCLUSIONS The results indicate that, in the context of a treated orchard, plum curculios exposed to dried pesticide residues may be capable of foraging before succumbing to toxicant exposure, while exposure to pesticides such as esfenvalerate may rapidly incapacitate adult plum curculios. copyright 2012 Society of Chemical Industry JF - Pest Management Science AU - Leskey, Tracy C AU - Wright, Starker E AU - Saguez, Julien AU - Vincent, Charles AD - USDA-ARS, Appalachian Fruit Research Station, Kearneysville, WV, USA.

We measure healthfulness several different ways to ensure robustness, but all measurements place a greater value on fresh fruits and vegetables and whole grains than on processed foods high in sugar and sodium. We find that from 1998-2006 consumers generally purchased less healthful foods at supercenters than they do at supermarkets. Moreover, a one-percent increase in the local market share of supercenters results in a decrease in purchase healthfulness for groceries of 0.10 to 0.46 percent. This relationship is statistically significant and robust.

The analysis is applied to experimental data on Wisconsin corn yields from 1990 to 2010. Relying on a Heckman-like factor that accounts for selectivity, we find evidence of selection bias, indicating that some of the observed yield advantage associated with GM hybrids can be attributed to their conventional genes. We document how the rising market concentration of biotech firms has contributed to increasing selectivity bias in corn yield. The impact, however, is offset by the negative effect of the rising adoption rate of GM corn on selectivity bias.

The majority of these hyperthermic soils fall within the aridic soil moisture regime, areas of minimal soil moisture commonly associated with desert shrubs. However, field indicators suggest that the hyperthermic soil temperature regime also impacts areas with slightly increased soil moisture typically associated with desert grasslands. These "hot desert grasslands" would represent soil climates that are transitional from hyperthermic to thermic soil temperature regimes within the aridic soil moisture regime and suggest an expansion of desert shrub landscapes into desert grassland landscapes due to increasing soil temperature. A combination of plant indicators such as leatherstem (Jatropha dioica), guayacan (Guaiacum angustifolium), Chino grama (Bouteloua ramosa), and others, as well as elevation, slope gradient and aspect were used to identify hyperthermic soils in areas with increased soil moisture. Management will need to adapt to climate change especially in the transitional zones.

S.T. Blake (Myrtaceae) as a result of the mutualistic association between the fly Fergusonina turneri Taylor (Diptera: Fergusoninidae) and its obligate nematode Fergusobia quinquenerviae Davies & Giblin-Davis (Tylenchida: Sphaerulariidae). The nematode induces gall formation, whereas the fly promotes gall maturation. Together they exploit M. quinquenervia buds and may inhibit stem elongation and flower formation. We delimited the physiological host range of this pair to determine their suitability as biological control agents of invasive M. quinquenervia populations in Florida, USA. Host use was assessed for eight species of Myrtaceae native to Florida, eight phylogenetically related ornamental species and oviposition alone on five non-myrtaceous species. Although oviposition was less specific, galls developed and matured only on M. quinquenervia. After establishment, galls are predicted to prevent flower and seed production, thereby reducing the regenerative potential of M. quinquenervia. This is the first example of an insect/nematode mutualism released as biological control agents of an invasive plant.

The resultant data will eventually be incorporated into models such as the Wind Erosion Prediction System (WEPS). A replicated field experiment was conducted in the fall of 2010 on two soils that dominate the military training grounds at Fort Riley, Kansas. Treatments consisted of two vehicle types and three levels of vehicle passes. We used an Abrams M1A1 tank and a High-Mobility Multipurpose Wheeled Vehicle (i.e., Humvee), representing tracked and wheeled military vehicles, respectively. Bulk density, aboveground standing biomass, and plant cover were measured before and after vehicular traffic in the fall of 2010 as well as in the spring and summer of 2011. Samples were taken from curved, straight, and cross-over sections of the vehicle tracks. A mixed-model analysis of variance of these data indicated that the overall mean bulk density under the M1A1 was significantly greater than under the Humvee (p less than or equal to 0.05). In general, as the number of passes increased, the bulk density under the M1A1 increased significantly (p less than or equal to 0.05), but the increases under the Humvee were not significant (p less than or equal to 0.05). Bulk densities were significantly greater in the curved part of the tracks than the straight part of the tracks. Reduction in standing biomass and vegetation cover was more severe on average under the M1A1 than under the Humvee (although not significant at p less than or equal to 0.05). For both vehicles, biomass and cover were affected more at the curved sections of the track than the straight sections (significant at p less than or equal to 0.05). Comparison of spring and fall bulk density data showed significant differences at the 0-5 cm and 5-10 cm depths, indicating that the winter freeze and thaw cycles loosened the top soil layers. Subsequent growth showed severe reduction in grass biomass growth in the curved sections of the tracked vehicle paths. Growth inforb species was not significantly affected.

In this study, we demonstrate that biofilm formation in EHEC O157:H7 strain 86-24 is highly repressed compared to that in an isogenic hha mutant. The hha mutant produced large quantities of biofilm compared to the wild-type strain at 30 degree C and 37 degree C. Complementation of the hha mutant reduced the level of biofilm formation to that of the wild-type strain, indicating that Hha is a negative regulator of biofilm production. While swimming motility and expression of the flagellar gene fliC were significantly reduced, the expression of csgA (encoding curlin of curli fimbriae) and the ability to bind Congo red were significantly enhanced. The expression of both fliC and csgA and the phenotypes of motility and curli production affected by these two genes, respectively, were restored to wild-type levels in the complemented hha mutant. The csgA deletion abolished biofilm formation in the hha mutant and wild-type strain, and csgA complementation restored biofilm formation to these strains, indicating the importance of csgA and curli in biofilm formation. The regulatory effects of Hha on flagellar and curli gene expression appear to occur via the induction and repression of FlhDC and CsgD, as demonstrated by reduced flhD and increased csgD transcription in the hha mutant, respectively. In gel shift assays Hha interacted with flhDC and csgD promoters. In conclusion, Hha regulates biofilm formation in EHEC O157:H7 by differential regulation of FlhDC and CsgD, the global regulators of motility and curli production, respectively.

Concerns have been raised that therapeutic use of ceftiofur in cattle may increase the prevalence of ESCr E. coli. We report that herd ESCr E. coli fecal and hide prevalences throughout the residency of cattle at a feedlot, including during the period of greatest ceftiofur use at the feedlot, were either not significantly different (P greater than or equal to 0.05) or significantly less (P < 0.05) than the respective prevalences at arrival. Longitudinal sampling of cattle treated with ceftiofur demonstrated that once the transient increase of ESCr E. coli shedding that follows ceftiofur injection abated, ceftiofur-injected cattle were no more likely than untreated members of the same herd to shed ESCr E. coli. Pulsed-field gel electrophoresis (PFGE) genotyping, antibiotic resistance phenotyping, screening for presence of the blaCMY-2 gene, and plasmid replicon typing were performed on 312 ESCr E. coli isolates obtained during six sampling periods spanning the 10-month residence of cattle at the feedlot. The identification of only 26 unique PFGE genotypes, 12 of which were isolated during multiple sampling periods, suggests that clonal expansion of feedlot-adapted blaCMY-2 E. coli strains contributed more to the persistence of blaCMY-2 than horizontal transfer of IncA/C plasmids between E. coli strains at this feedlot. We conclude that therapeutic use of ceftiofur at this cattle feedlot did not significantly increase the herd prevalence of ESCr E. coli.

Microbial screening methods commonly used for monitoring veterinary drug residues are not sensitive or selective for fluoroquinolones. In this work, a luminescence-based screening assay was developed to detect fluoroquinolones in beef serum. This approach takes advantage of the DNA-enhanced luminescence signal of a fluoroquinolone-Tb super(+3) complex. In this method, serum samples were extracted with acidified acetonitrile in the presence of magnesium sulfate. After centrifugation, evaporation of the supernatant was followed by dissolution of the residue in buffer and filtration. Addition of Tb super(+3) and DNA then allowed a reading of the luminescence signal. The technique was illustrated using enrofloxacin, and provided good recoveries (73-88%) at 25, 50 and 100 ng ml super(-1), with reasonable RSDs averaging at 11%. The LOD was 2.5 ng ml super(-1) based on the variability of response of control serum samples from 18 different steers. The method provided no false-positive or false-negative results while screening blind samples for enrofloxacin and was demonstrated to be quantitative over a range of 0-100 ng ml super(-1).

Evidence For Insect Pollination in Tanoaks AN - 1427013223; 18418037 AB - Tanoaks, Notholithocarpus densiflorus (Hook. & Arn.) Manos, Cannon & S. H. Oh, are being killed by sudden oak death, caused by the pathogen Phytophthora ramorum Werres, de Cock & Man in't Veld. However, very little is known about the basic ecology of the species. Here we investigate the pollination ecology of tanoaks using insect-visitor observations along with a pollinator-exclusion study. Insect-visitor observations were conducted by citizen-scientist volunteers at three different sites in the Midpeninsula Regional Open Space District lands in the Coast Range of California in 2009. Pollinator exclusions were conducted over two years (2009, 2010), using veil bags to prevent insects from reaching female flowers at the Blodgett Forest Research Station in the Sierra Nevada foothills. Microsatellite markers were used to infer selfing or outcrossing for the developing acorns. The citizen scientists observed 148 insect visitors to tanoak flowers over 11.5 hours of observation (in 65 observation periods). Pollinator exclusion resulted in lower fruit set and higher rates of selfing. The data suggest that tanoak is primarily an insect-pollinated species, though some level of wind pollination is likely. There is a diverse community of insects visiting tanoak flowers. In order to understand the importance of tanoaks to the native insect community, future research needs to focus on identifying the composition of the insect community, and the extent to which they rely on tanoak pollen and nectar as a food source.

In spite of this, few current soil erosion models account for these changes. To begin to address this deficiency, a spatially distributed version of RUSLE2 was developed and used in combination with the tillage erosion model TELEM. These models were applied to a 6.6 ha research watershed near Treynor, Iowa, where runoff and sediment yield were measured from 1975 to 2002. The watershed contained a grassed waterway, and ~I m wide grass hedges were established in 1991, with 15.4 m intervals between the grass hedges. Beginning in 1996, no-till management replaced conventional tillage management in the watershed. Using a 3 m raster DEM, concentrated flow channels that ended RUSLE2 hills lope profiles were delineated wherever contributing areas exceeded 600 m2. Average monthly runoff and sediment delivery to concentrated flow areas were compared with measured monthly runoff and sediment delivery at the watershed outlet. For conventional tillage, monthly runoff patterns reasonably matched observations, but measured watershed sediment yield was lower than RUSLE2-predicted hills lope sediment delivery, suggesting that sediment was deposited in the grassed waterway. Grass hedges reduced sediment yield similarly in the RUSLE2 estimates and the measured watershed sediment yield. Conversion to no-till had a much greater impact in reducing RUSLE2 estimates of hillslope erosion than it did on measured watershed sediment yield, suggesting that ephemeral gully erosion remained an important sediment source in this watershed under no-till conditions. To assess the potential influence of distributed patterns of soil erosion and deposition behind the hedges on future erosion estimates, the terrain elevation was modified by summing estimates of water and tillage erosion and deposition that would be expected from 50 years of conventional tillage. As expected, reduced slope gradients generally reduced future erosion. The lack of consideration of erosion or deposition in concentrated flow channels limiied the abiliiy of the modeling scheme to reinforce existing ephemeral gully channels.

On upland areas, these processes are usually thought of as detachment and transport of soil particles by rainfall and surface flow. One of the most difficult processes to quantify is sediment transport. This process depends on a host of factors including sediment type, size, size distribution, and concentrations on one hand and the flow regime relative to rates and velocities on the other hand. The effect of all of these factors is influenced by soil surface cover and surface roughness conditions. The National Sedimentation Laboratory has in recent years conducted a series of basic laboratory studies to better understand sediment movement in shallow overland flow. These experiments involved super-critical flow regimes in a 7 m long and 10 cm wide channel in which sand-size material was seeded at the upstream end at controlled rates in a super-critical flow regime with Froude numbers >1. Particle sizes were coarse sand (1000 to 1400 mu m), medium sand (600 to 850 mu m), and spherical glass beads (600 to 1000 fan). Measurements included particle velocity and particle concentrations using photonic probes. Three modes of transport were noted: a saltation mode at low concentrations, sediment waves in which sediment moved in regularly spaced waves, and a meander mode. The latter two modes were attributed to particle interactions. The transported sediment was continuously collected at the downstream end by a rotating sampler. A curvilinear increase in transport rate was noted with an increase in seeding rate until a critical saltation limit was reached, after which a decrease in sediment movement occurred with the formation of organized sediment structures. The small structures were waves with spacings of the order of magnitude of tens of particle diameter, while the larger-scale meander had wavelengths of hundreds of particle diameters. The measured pseudo-equilibrium transport rates were smallest in the meander mode, followed by the wave mode. A relationship was obtained that described the transition from the saltation mode to the wave mode in terms of a critical solid concentration.

Likewise, basic small watershed configurations of a few hillslopes and channels can be created and simulated with this GUI. However, as the catchment size increases, the complexity of developing and organizing all WEPP model inputs greatly increases due to the multitude of potential variations in topography, soils, and land management practices. For these types of situations, numerical approaches and special user interfaces have been developed to allow for easier WEPP model setup, utilizing either publicly available or user-specific geospatial information, e.g., digital elevation models (DEMs), geographic information system (GIS) soil data layers, and GIS land use/land cover data layers. We utilize the Topographic Parameterization (TOPAZ) digital landscape analysis tool for channel, watershed, and sub-catchment delineation and to derive slope inputs for each of the subcatchment hills lope profiles and channels. A user has the option of specifying a single soil and land management for each subcatchment or utilizing the information in soils and land use/land cover GIS data layers to automatically assign those values for each grid cell. Once WEPP model runs are completed, the output data are analyzed, results interpreted, and maps of spatial soil loss and sediment yields are generated and visualized in a GIS. These procedures have been used within a number of GIS platforms including GeoWEPP, an ArcView/ArcGIS extension that was the first geospatial interface to be developed in 2001. GeoWEPP allows experienced GIS users the ability to import and utilize their own detailed DEM, soil, and/or land use/land cover information or to access publicly available spatial datasets. A web-based GIS system that used MapServer web GIS software for handling and displaying the spatial data and model results was initially released in 2004. Most recently, Google Maps and OpenLayers technologies have been integrated into the web WEPP GIS software to provide significant enhancements. This article discusses in detail the logic and procedures for developing the WEPP model inputs, the various WEPP GIS interfaces, and provides example real-world geospatial WEPP applications. Further work is ongoing in order to expand these tools to allow users to customize their own inputs via the internet and to link the desktop GeoWEPP with the web-based GIS system.

Pond ash (PA), a by-product of coal-fired electrical generation, has been proposed as a feedlot pen surface amendment because of its foundational support characteristics. A study was conducted to compare the performance of PA-surfaced pens to traditional soil-surfaced (SS) pens. Four of eight SS pens (7.3 m x 20.7 m) were excavated to a depth of 0.5 m and resurfaced with PA. The remaining four pens were kept as SS. Eight heifers were housed in each pen (19 m(2) head(1)) for four feeding cycles that ranged from 73 to 172 days. Following each feeding cycle, the animals were removed and the pens were cleaned. A subsample of the accumulated manure was removed from each pen for analysis of total mass (TM), total solids (TS), volatile solids (VS), percent volatile solids (VS%), moisture, and ash content. Higher heating value (HHV) was estimated using the VS% and moisture content. As compared to the SS pens, surfacing pens with PA reduced TM by 34%, TS by 34%, and ash content by 46%. PA increased VS% by 70% and HHV by 75%. Restoring the PA-surfaced pens to the original grade required only 25% of the amount of fill material required for the SS pens. However, there were no differences in the total amount of VS removed. Harvested feedlot surface material (FSM) from the PA pens was more nutrient and energy dense, based on the increased VS% of the collected material.

Atmospheric stability is an important input parameter to such models. The objective of this study was to compare emission rates calculated with a backward Lagrangian stochastic (bLS) inverse-dispersion model (WindTrax) using three different methods for calculating atmospheric stability: sonic anemometer, gradient Richardson number, and Pasquill-Gifford (P-G) stability class. Ammonia and methane emission data from a compost yard at a 10,000-cow dairy were used for the comparisons. Overall, average emission rates were not significantly different among the stability methods. Emission rates correlated well between the sonic and other methods (r super(2) > 0.79, p < 0.001). The slopes of the regression lines between the sonic and Richardson methods were 0.95 and 1.0 for CH sub(4) and NH), respectively. The regression line slopes for the P-G method were about 1.9 for CH sub(4) and 1.6 for NH sub(3), which means emission rates predicted with the P-G method tended to be 50% to 100% greater than rates predicted with sonic anemometer data. Based on this limited data set, using the gradient Richardson method to represent atmospheric stability resulted in emission rates that more closely matched emission rates from the sonic method. Considering the amount of variability inherent in emissions calculations, a three-dimensional sonic anemometer should be used, if possible, to directly provide the necessary data to calculate parameters representing wind properties, rather than inferring values from other stability classification methods.

Therefore, a rangeland site can be highly vulnerable to soil erosion where overland flow is likely to concentrate and exert high shear stress on soil grains. This concept is commonly applied in cropland and wildland soil erosion modeling using predictions of flow effective shear stress (shear stress applied on soil grains). However, historical approaches to partition shear stress in erosion models are computationally complex and require extensive parameterization. Furthermore, most models are not capable of predicting the conditions in which concentrated flow occurs on rangelands. In this study, we investigated the rangelands conditions at which overland flow is more likely to become concentrated and developed equations for partitioning the shear stress of concentrated flow on rangelands. A logistic equation was developed to estimate the probability of overland flow to become concentrated. Total shear stress of rangeland overland flow was partitioned into components exerted on soil, vegetation, and rock cover using field experimental data. In addition, we investigated the vegetation cover limit at which the effective shear stress component is substantially reduced, limiting the erosion rate. The results from the partitioning equations show that shear stress exerted on soil grains was relatively small in sheet flow. Shear stress exerted on soil grains in concentrated flow was significantly higher when bare soil exceeded 60% of the total surface area but decreased significantly when the bare soil area was less than 25% or when the plant base cover exceeded 20%. These percentages could be used as relative measures of hydrologic recovery for disturbed rangelands or as triggers that indicate a site is crossing a threshold beyond which soil erosion might accelerate due to the high effective shear stress.

This study extended WEPS to run on multiple fields (grid cells) independently to cover a large region and conducted an initial investigation to assess how well WEPS performed in that environment by comparing simulations for two historical dust events with field observations and satellite images in the Columbia Plateau region of Washington. We modified the WEPS source code to allow it not only to run on multiple grid cells but also to save the state of the simulation so that it can be re-initiated from that state in future runs, allowing the model to be started and then stepped through time incrementally under various future climate or forecast weather scenarios. We initially ran WEPS on the entire state of Washington, with the entire Pacific Northwest region as our ultimate target area, to provide PM sub(10) and eventually PM sub(2.5) emissions from wind erosion events as input to the chemical transport model CMAQ, which is used by the AIRPACT regional air quality modeling system for the Pacific Northwest. Three principal inputs to WEPS are meteorological data, soil data, and crop management practices. These data, at a 1 km x 1 km grid cell resolution, are the basic input data for running the spatially distributed model. The climatic data from a three-year period were stochastically generated based on statistical representations of past meteorological measurements from stations in the region and were used for initializing WEPS, and then a three-day set of meteorological data corresponding with historical dust storm events were selected for simulation by WEPS of wind erosion of cropland in the state of Washington. The crop management data were selected based on the land use and USDA Natural Resources Conservation Service (NRCS) crop management zones, and the soil data were derived from the NRCS SSURGO database. We aggregated the outputs from 1 km x 1 km grid cells into 12 km x 12 km grid cells for easier visualization and then mapped the total surface soil erosion, suspension, and PM sub(10) emissions for each 12 km x 12 km grid cell. This study shows that WEPS can be successfully extended to run from one field grid cell to multiple field grid cells, and the model can identify regions with high potential for soil erosion by wind. It also demonstrates that WEPS can be used for real-time monitoring of soil erosion and air quality in a large region if actual and forecast weather inputs are available.

For an efficient evaluation and characterization of the most useful agronomic and disease-resistant traits, an even smaller collection of peanut accessions that represent a spectrum of phenotypes could be more desirable. For this reason, a mini-mini core collection with 99 accessions from the core accessions was developed based on the analysis of 21 morphological traits. It was demonstrated that there were no significant differences between the core and mini-mini core collections in 20 out of the 21 morphological traits studied. Further, the mini-mini core collection captured the ranges of all of the 21 traits displayed in the core collection. The newly developed mini-mini core collection was assessed for resistance to bacterial wilt disease caused by Ralstonia solanacearum. Two accessions showing a high level of resistance to bacterial wilt were identified, demonstrating the usefulness of the mini-mini core collection. The mini-mini-core collection provides a more efficient means of germplasm evaluation and will be resequenced as part of the International Peanut Genome Consortium sequencing project at the UC-Davis Genome Center.

In seeking disease management alternatives, the inhibitory activity of alkaloids extracted from the Red Imported Fire Ant was studied in the laboratory and the greenhouse. Piperidine and piperideine alkaloids each significantly inhibited CMM growth on nutrient agar plates. The inhibitory activity of piperidine alkaloids was stable at 4 super( degree ) C and 22 super( degree ) C for 12 weeks and at 54 super( degree ) C for 4 weeks. The growth of CMM was negatively correlated with the concentration of piperidine alkaloids in nutrient broth. In the greenhouse, piperidine alkaloids also significantly reduced the symptom development on two tomato cultivars, Better Boy and DRK7018F1. This is the first demonstration that piperidine and piperideine alkaloids from the Red Imported Fire Ant are highly inhibitory against a plant-pathogenic bacterium, viz. CMM. Piperidine alkaloids could provide satisfactory management of CMM bacterial canker on tomato seedlings in the greenhouse. Our findings may lead to the development of a new group of bactericides.

'Candidatus Liberibacter solanacearum' Liefting et al. has been associated with ZCD. This non-culturable bacterium dwells within the phloem of plants where other endophytic bacteria may also live. Knowledge concerning phloem colonization by 'Ca. L. solanacearum' and other endophytic bacteria may provide a better understanding about disease biology and could facilitate the development of novel disease management strategies. In this study, endophytic bacteria in potato tubers afflicted with ZCD were evaluated by scanning electron microscopy (SEM), in vitro cultivation, and PCR analyses. Bacillus, coccus, and filamentous bacterial cells were observed by SEM in phloem tissue of ZCD-diseased tubers, but were absent in healthy potato tubers. Fifty-one bacterial isolates were obtained in vitro from ZCD-affected tubers and 34 isolates were from non-ZCD tubers. Comparison of 16S rDNA sequences identified bacteria belonging to 16 genera. Seven (Brachybacterium, Enterobacter, Microbacterium, Paenibacillus, Staphylococcus, Stenotrophomonas and Variovorax) were only isolated from ZCD-affected potato tubers, whereas four (Bosea, Nocardia, Sphingomonas and Sphingopyxis) were only isolated from non-ZCD potato tubers. However, a more sensitive PCR analysis diminished the specific association of the bacteria to either ZCD or non-ZCD tubers, suggesting that infection by 'Ca. L. solanacearum' influenced the titres of other endophytic bacteria in potato tubers.

Insects examined were from infested tree branches collected from sites in New York and Illinois. Staphylococcus sciuri (Kloos) was the most common isolate associated with adults, from 13 of 19 examined, whereas members of the Enterobacteriaceae dominated the isolations from larvae. Leclercia adecarboxylata (Leclerc), a putative pathogen of Colorado potato beetle, Leptinotarsa decemlineata (Say), was found in 12 of 37 larvae examined. Several opportunistic human pathogens, including S. xylosus (Schleifer and Kloos), S. intermedius (Hajek), S. hominis (Kloos and Schleifer), Pantoea agglomerans (Ewing and Fife), Serratia proteamaculans (Paine and Stansfield) and Klebsiella oxytoca (Flugge) also were isolated from both larvae and adults. One isolate, found in 1 adult and several larvae, was identified as Tsukamurella inchonensis (Yassin) also an opportunistic human pathogen and possibly of Korean origin.. We have no evidence that any of the microorganisms isolated are pathogenic for the Asian longhorned beetle.

Current detection programs by federal and state agencies in the United States use a grid of traps consisting of liquid methyl eugenol (lure) and naled (toxicant) applied to cotton wicks and hung inside the trap. In recent years efforts have been made to incorporate these chemicals into various solid-type matrices that could be individually packaged to reduce human exposure to the chemicals and improve handling. New solid formulations containing methyl eugenol and either naled or dichlorovinyl dimethyl phosphate toxicants were compared with the standard formulations on cotton wicks in large scale field evaluation in Hawaii. Two reduced risk toxicants (spinosad and Rynaxypyr) were also evaluated. In one test the solid lure-toxicant-matrix combinations were sent to California to be weathered under California climate conditions and then sent back to Hawaii for evaluation. The polymer matrices with lure and toxicant were found to be as attractive as baited wicks and have the same longevity of attraction regardless of being weathered in Hawaii or in California. The new ingestible toxicants were also effective, although further testing of these ingestible lure + toxicant + matrix products is necessary.

Trees with large basal cankers, known to attract scolytid beetles, had a 4.3 times higher ethanol level than trees with spot cankers that attract fewer beetles. Ethanol concentrations inside cankers, where scolytid beetles preferentially attack, varied by about four orders of magnitude among samples, with a median level of 16.0 mu g.g super(-1) fresh mass. This concentration was 4.3 and 15.5 times greater, respectively, than the concentrations at 1 cm or 15-30 cm outside the canker boundaries. In the laboratory, we demonstrated that ethanol escaped through the bark of a Q. garryana log just 3 days after it was added to the sapwood. At the three study sites, traps baited with ethanol captured more Xyleborinus saxesenii, Pseudopityophthorus pubipennis, and Monarthrum dentiger (all Coleoptera: Curculionidae: Scolytinae) than traps baited with ethanol plus (-)- alpha -pinene, or ethanol plus 4-allylanisole (4AA). Logs of Q. agrifolia with a 50 % ethanol solution added to the sapwood were placed at the study sites, with or without additional bark treatments above the ethanol. The number of scolytid beetle gallery holes above the ethanol-infused sapwood was 4.4 times greater than that on the opposite side of the log where no ethanol was added. Attachment of ultra-high release (-)- alpha -pinene pouches to the bark surface above the 50 % ethanol solution reduced scolytid attacks to a density of 19.1 % that of logs without this treatment. We conclude that ethanol in P. ramorum cankers functions as a primary host attractant for scolytid beetles and is an important link in colonization of these cankers and accelerated mortality of Q. agrifolia. The results of this research shed light on the chemical ecology behind the focused scolytid attacks on P. ramorum-infected coast live oaks, and lay the groundwork for future efforts to prolong the survival of individual trees of this keystone species.

Staphylococcal phage 2638A endolysin is a peptidoglycan hydrolase that is lytic for S. aureus when exposed externally, making it a new candidate antimicrobial. It shares a common protein organization with more than 40 other reported staphylococcal peptidoglycan hydrolases. There is an N-terminal M23 peptidase domain, a mid-protein amidase 2 domain (N-acetylmuramoyl-L-alanine amidase), and a C-terminal SH3b cell wall-binding domain. It is the first phage endolysin reported with a secondary translational start site in the inter-lytic-domain region between the peptidase and amidase domains. Deletion analysis indicates that the amidase domain confers most of the lytic activity and requires the full SH3b domain for maximal activity. Although it is common for one domain to demonstrate a dominant activity over the other, the 2638A endolysin is the first in this class of proteins to have a high-activity amidase domain (dominant over the N-terminal peptidase domain). The high activity amidase domain is an important finding in the quest for high-activity staphylolytic domains targeting novel peptidoglycan bonds.

We used a coupled gas chromatograph-electroantennographic detector (GC-EAD) to assay the olfactory sensitivity of the southern pine beetle, Dendroctonus frontalis Zimmermann, to volatiles from leaves and bark of eight species of nonhost angiosperm trees that are common in the range of D. frontalis. Tree species sampled were red maple (Acer rubrum L.), mockernut hickory [Carya alba (L.) Nutt. ex Ell.], sweetgum (Liquidambar styraciflua L.), black tupelo (Nyssa sylvatica Marsh.), black cherry (Prunus serotina Ehrh.), southern red oak (Quercus falcata Michx.), blackjack oak [Quercus marilandica (L.) Muenchh.], and water oak (Quercus nigra L.). Beetle antennae responded to a total of 28 identifiable compounds in these samples. The relative olfactory responsiveness to 14 of these, as well as to nonanoic acid and four additional volatiles reported to be associated with nonhost angiosperms, was assessed in GC-EAD analyses of synthetic dilutions spanning six orders of magnitude. The largest response voltage amplitudes were obtained with trans-conophthorin, nonanoic acid, terpinen-4-ol, phenylethyl alcohol, and eucalyptol, whereas the lowest response thresholds were to nonanoic acid, nonanal, linalool, (E)-2-hexen-1-ol, and phenylethyl alcohol. Funnel traps baited with various combinations of eleven antennally-active angiosperm volatiles along with a standard attractant captured significantly fewer male and female D. frontalis than traps baited with the standard attractant alone. Our data suggest that a diversity of semiochemicals may be involved in host species discrimination by D. frontalis, and several may have utility in their management.

Rarely is the entire range of a taxon the subject of study. We examined the landscape genetic structure of the endangered Point Arena mountain beaver (Aplodontia rufa nigra), whose isolated geographic range is found in a restricted (85 km super(2)) but heterogenous region in California. Based on its diminutive range we may predict widespread gene flow and a relatively weak role for landscape variation in defining genetic structure. We used skin, bone, tissue and noninvasively collected hair samples to describe genetic substructure and model gene flow. We examined spatial partitioning of multilocus DNA genotypes and mitochondrial DNA haplotypes. We identified 3 groups from microsatellite data, all of which had low estimates of effective population size consistent with significant tests for historical bottlenecks. We used least-cost-path analysis with the microsatellites to examine how vegetation type affects gene flow in a landscape genetics framework. Gene flow was best predicted by a model with "Forest" as the most permeable, followed by "Riparian". Agricultural lands demonstrated the highest resistance. MtDNA data revealed only two haplotypes: one was represented in all 57 individuals that occurred north of the east-west flowing Garcia River. South of the river, however, both haplotypes occurred, often at the same site suggesting that the river may have affected historical patterns of genetic divergence.

We previously tested a vertical-lift incubator (the "See-Saw") using Channel Catfish spawns. When loaded with spawns at rates higher than recommended for traditional paddle-type incubators, as often occurs during the peak of the spawning season, survival to the swim-up stage was significantly (2.3 times) higher with the See-Saw than with traditional incubators. This project examined the effect of spawn loading rate and added oxygen on fry production with the See-Saw. In study 1, See-Saws were loaded with 15.0 plus or minus 0.1 lb (mean plus or minus SE; 219,825 eggs), 30.1 plus or minus 0.1 lb (446,055 eggs), 45.1 plus or minus 0.1 lb (668,206 eggs), or 60.1 plus or minus 0.1 lb (891,157 eggs) of spawns per trough. Water flow averaged 2.1 gal/min-roughly 40% of the rate recommended for paddle-type incubators. Swim-up fry production increased in proportion to egg loading density up to 45 lb/trough, with the 15-, 30-, and 45-lb loading rate treatments producing 132,658, 263,828, and 429,422 swim-up fry, respectively. However, the 60-lb treatment produced only 417,237 swim-up fry. Survival to the swim-up stage in the 15-, 30-, and 45-lb treatments averaged 60 plus or minus 9, 59 plus or minus 6, and 64 plus or minus 4%, respectively, but survival to swim-up in the 60-lb treatment averaged only 46 plus or minus 8%. In study 2, the addition of purified oxygen to See-Saw incubators loaded with 36 spawns/trough ( similar to 45 lb/trough) increased the DO concentration by 4.0 ppm (to 125% air saturation) but had no effect on survival to swim-up. The See-Saw incubator can effectively incubate up to 45 lb of spawns (670,000 eggs)-up to three times as many eggs as traditional paddle-type incubators-while using less than half the water; thus, the See-Saw incubator can provide significant savings in space, water, and energy use.

This disease can greatly diminish the profitability of aquaculture operations by large-scale mortality events, particularly in the fingerling production phase. Three experiments were conducted to evaluate the susceptibility of Channel Catfish fingerlings to columnaris disease when they were preexposed to copper sulfate (CuSO sub(4)). In experiment 1, fish were exposed for 24 h to 0, 1, 2, or 4 mg/L CuSO sub(4) and were challenged immediately with Flavobacterium columnare, the etiological agent of columnaris disease. The resulting survival data indicated that fish preexposed to CuSO sub(4) and then challenged exhibited significantly lower survival than did fish not exposed and then challenged. Experiment 2 was designed as above, except after the 24-h static exposure to CuSO sub(4), fish were subjected to an additional 24 h in flow-through water prior to the challenge with F. columnare. In contrast to experiment 1, fish preexposed to CuSO sub(4) and allowed an additional 24 h in flow-through water had a significantly higher survival rate than fish not exposed and then challenged. Experiment 3 evaluated the longevity of resistance to columnaris disease afforded by preexposure to CuSO sub(4); in this experiment the remaining fish from experiment 2 were challenged 9 d after exposure to CuSO sub(4). The increased survival rate of fish preexposed to CuSO sub(4) was still significantly different, indicating the incurred resistance to F. columnare lasts for at least a week after exposure to CuSO sub(4).

This review tabulates at least 100 mammal species with evidence of WNV exposure. Many of these exposures were detected in free-ranging mammals, while several were noted in captive individuals. In addition to exposures, this review discusses experimental infections in terms of the potential for reservoir competence of select wild mammal species. Overall, few experimental infections have been conducted on wild mammals. As such, the role of most wild mammals as potential amplifying hosts for WNV is, to date, uncertain. In most instances, experimental infections of wild mammals with WNV have resulted in no or low-level viremia. Some recent studies have indicated that certain species of tree squirrels (Sciurus spp.), eastern chipmunks (Tamias striatus), and eastern cottontail rabbits (Sylvilagus floridanus) develop viremia sufficient for infecting some mosquito species. Certain mammalian species, such as tree squirrels, mesopredators, and deer have been suggested as useful species for WNV surveillance. In this review article, the information pertaining to wild mammal associations with WNV is synthesized.

Spreng], swampbay [P. palustris (Raf.) Sarg.], avocado (P. americana Mill.), and sassafras [Sassafras albidum (Nutt.) Nees]. Xyleborus glabratus is attracted to manuka oil lures, which are commercially available, and phoebe oil. Variable efficacy of manuka oil lures and insufficient availability of phoebe oil prompted us to investigate the reasons behind changes in manuka oil lure efficacy and to test cubeb oil, a readily available essential oil from Piper cubeba L. seeds, as an alternative attractant. Attraction, release rates and durations, and volatile composition of manuka oil lures manufactured in 2008 were compared with manuka oil lures manufactured in 2012, and to whole and a distilled fraction of cubeb oil. Manuka oil lures from 2008 were more attractive to X. glabratus than controls for 8 wk, whereas lures from 2012 were attractive for only 2 wk. Cubeb oil and the distilled fraction of it were as attractive as or more attractive than manuka oil in three trials. In gravimetric studies, manuka oil lures from 2008 and cubeb oil lures continued to release volatiles for 57 d, whereas lures from 2012 stopped after 16 d. The chemical composition of volatiles released from new manuka oil lures from 2008 was similar to 2012; however, a preservative (butylated hydroxytoluene) was detected in the 2008 lures. Cubeb oil was an effective attractant for X. glabratus that lasted 8-9 wk when released from bubble lures.

Contour maps were constructed to measure population distributions in and around orchards. Our results indicate that Anastrepha populations are focused around host fruit in both space and time, that traps do not draw fruit flies away from hosts, even when placed within 15 m of the host, and that lures continue to function for 6 mo in the field. The contour mapping analyses reveal that populations of fruit flies are focused around ovipositional hosts. Although the trapping system does not have a very long effective sampling range, it is ideal, when used in combination with contour analyses, for assessing fine-scale (on the order of meters) population distributions, including identifying resources around which fly populations are focused or, conversely, assessing the effectiveness of management tools. The results are discussed as they pertain to monitoring and detecting Anastrepha spp. with the McPhail-type trap and ammonium acetate and putrescine baiting system and the dispersal of these flies within Puerto Rico.

The Jeffrey pine beetle, Dendroctonus jeffreyi Hopkins (Coleoptera: Curculionidae: Scolytinae), is monophagous on Jeffrey pine and its primary insect pest. Despite the importance of P. jeffreyi, difficult terrain, environmental concerns, and lack of roads can constrain pest management activities. Semiochemicals are often easier to apply and more environmentally acceptable than other options, but they are lacking in this system. Attractants have been identified, but field bioassays have been limited because of infrequent or short duration outbreaks and a lack of beetles during nonoutbreak periods. Disruptant semiochemicals have not been assessed for D. jeffreyi during outbreak conditions; however, commercially available semiochemicals have been implicated as disruptants for this bark beetle. The objective of this study was to identify the most effective commercially available attractant and disruptant semiochemicals for D. jeffreyi. Our highest observed catch occurred with the blend of 5% 1-heptanol and 95% n-heptane. When this was used to challenge potential disruptant semiochemicals, the combination of S-(-)-verbenone and the green leaf volatile blend (cis-3-Hexenol and 1-Hexanol) reduced trap catch by approximately 80%. However, frontalin was most effective, reducing the number of D. jeffreyi caught by >96%. Within each year of the study, the percentage female of D. jeffreyi caught with our attractant decreased from start to end of the experimental period. On average, our first collection in a year (mid-June to early July) was 59% female, whereas our last (mid-August) was 34%. Frontalin was equally or more effective against females (the pioneering sex) than males, providing optimism that semiochemical disruption may be possible for protecting Jeffrey pines from D. jeffreyi.

K. Koch. Prior research indicated the potential for use of Hypocreales fungi to suppress C. caryae. We compared the efficacy of two fungal spp., Beauveria bassiana (GHA strain) and Metarhizium brunneum (F52), in their ability to cause C. caryae mortality. The fungus, B. bassiana, was applied to trunks of pecan trees (a method previously shown to be effective in C. caryae suppression) and efficacy was compared with M. brunneum applied to the ground or to the trunk with or without SoyScreen Oil as an ultraviolet protecting agent. Results indicated B. bassiana to be superior to M. brunneum regardless of application method; consequently, the potential for applying B. bassiana to control C. caryae was explored further. Specifically, the impact of different fertilizer regimes (as used by pecan growers) on the persistence of B. bassiana (GHA) in soil was determined. B. bassiana was applied to soil in a pecan orchard after one of several fertilizer treatments-i.e., ammonium nitrate, crimson clover, poultry litter, clover plus poultry litter, and a no-fertilizer control. B. bassiana persistence up to 49 d in 2009 and 2010 was assessed by plating soil onto selective media and determining the number of colony forming units, and by baiting soil with a susceptible host, Galleria mellonella (L.). Fertilizer treatments did not impact B. bassiana persistence. We conclude that standard fertilizers for nitrogen management, when applied according to recommended practices, are unlikely to negatively impact survival of B. bassiana in pecan orchards when the fungus is applied for C. caryae suppression during weevil emergence. Additional research on interactions between entomopathogenic fungi and fertilizer amendments (or other tree nutrition or soil management practices) is merited.

Recent genotyping of B. cockerelli collected during the 2011 potato growing season identified three psyllid haplotypes within the western and central United States according to their geographical regions: northwestern, western, and central. To understand potato psyllid population dynamics before the year 2011, high resolution melting analysis of the B. cockerelli mitochondrial cytochrome oxidase I-like gene was used to identify the haplotypes of over 450 archived psyllids collected in the western and central United States between the years 1998 and 2010. Results show that the northwestern haplotype was present in Washington State as early as 1998 and has persisted in this region since that time. Likewise, psyllids of the western haplotype have also been present in Washington and Oregon before 2011.

The quorum sensing transcriptional regulator SdiA, a homolog of LuxR, has been shown in vitro to repress LEE strongly when overexpressed from a multi-copy recombinant plasmid or when its activity is enhanced by the binding of N-acyl-L-homoserine lactones (AHLs), the quorum sensing signals that are detected by SdiA. Since LEE has been shown to be essential for colonization and persistence of O157 in bovine intestine, we examined whether a mutation in sdiA, which normally represses LEE in vitro, would also exert negative effect on colonization and long-term persistence of O157 in weaned calves. Ten-week old weaned calves (n = 4/group) were inoculated orally with 1010 cfu of either the wild-type or sdiA mutant strain. Initial fecal shedding of the sdiA mutant and the wild-type strain were similar in magnitude and declined during the first 2 weeks post-inoculation. The sdiA mutant was detected in feces of only one of the four calves at low levels ( greater than or equal to 102 cfu/g feces) from days 19 - 27 post-inoculation, whereas, the fecal shedding of the wild-type strain persisted at approximately 4-logs in all four calves from days 19 - 27. We also confirmed that SdiA represses ler, which encodes a positive transcriptional regulator of LEE, in response to AHLs, and reduces adherence of O157 to HEp-2 cells. In conclusion, this study demonstrates that although in vitro the sdiA gene represses LEE and LEE-mediated adherence to cultured cells, the presence of sdiA is necessary for colonization of bovine large intestine that in turn promotes persistent fecal shedding of O157 by these animals.

AN - 1328521977; 17871427 AB - The Agricultural Resource Management Survey is the primary annual source of information on U.S. farms, but in a typical year one-third of sampled farms do not respond. We use Census of Agriculture data to study nonresponse to the survey and how it affects estimates in two econometric models. Despite larger farms responding less, the coefficients estimated from the respondent subsample always fall inside confidence intervals based on draws from the full sample of respondents and nonrespondents. Although nonresponse bias can vary by application, the findings suggest that bias is unlikely to undermine conclusions based on econometrics using respondent data.

In the present study, 169 isolates from rice (Oryza sativa) cultivars, with and without Pi-ta, were analyzed for their genetic identity using an international differential system, repetitive element-based polymerase chain reaction (Rep-PCR), and sequence analysis of PCR products of AVR-Pita1. These isolates belong to the races IA 1, IB 1, IB 17, IC 1, and IC 17 of M. oryzae. These isolates were further classified into 15 distinct groups by Rep-PCR. There was a predominant group within each race. Pathogenicity assays on 'Katy' (Pi-ta) and 'M202' (pi-ta) rice determined that IC 1 was virulent to Katy and M202; IB 17, IC 17, and most of IA 1 and IB 1 were avirulent to Katy and virulent to M202, suggesting that the Pi-ta gene in Katy is responsible for preventing infection by these isolates. Consistently, AVR-Pita1 was not amplified from 28 virulent isolates. One AVR-Pita1 allele was amplified by AVR-Pita1-specific primers in 78 avirulent isolates. Interestingly, different AVR-Pita1 alleles were found in each of the 12 avirulent isolates, as determined by DNA sequencing. Sequence analysis of 90 PCR products revealed 10 AVR-Pita1 haplotypes, 4 of which were new. In total, 12 amino acid changes were identified in the new variants when compared with the first described AVR-Pita sequence (AF207841). The finding of isolates with altered AVR-Pita1 from rice cultivars with and without Pi-ta suggests that these virulent isolates were adapted to the field environments in the southern United States. Further research will be needed to verify this prediction.

A collection of 567 triticale accessions originating from 21 countries was evaluated at the seedling stage for reaction to races of P. graminis f. sp. tritici with broad virulence, including TTKSK, TRTTF, and TTTTF. A high frequency (78.4%) of accessions was resistant to race TTKSK, with low infection types ranging from 0; to X. A selection of 353 TTKSK-resistant accessions was evaluated for reaction to three South African isolates of P. graminis f. sp. tritici with single and/or combined virulences to stem rust resistance genes SrSatu, Sr27, and SrKw present in triticale. Genes SrSatu, Sr27, and SrKw were postulated to be present in 141 accessions and contributed to TTKSK resistance. The remaining 212 resistant accessions may possess uncharacterized genes or combinations of known genes that could not be determined with these isolates. These accessions were further evaluated for resistance to races TTKST, TPMKC, RKQQC, RCRSC, QTHJC, QCCSM, and MCCFC. Resistance remained effective across the entire set of races in the majority of the accessions (n = 200), suggesting that the resistances are effective against a broad spectrum of virulence. In all, 129 (79.6%) resistant accessions with noncharacterized genes were resistant to moderately resistant in field stem rust nurseries at Debre Zeit (Ethiopia) and St. Paul (Minnesota). Results from evaluating F sub(2) populations derived from resistant-susceptible crosses revealed that resistance to TTKSK in triticale was conferred mostly by single genes with dominant effects.

Black-tailed prairie dogs (Cynomys ludovicianus) are such a species, and they may strongly affect the abundance and composition of grassland bird communities. We examined how prairie dog colonies in the North American Great Plains affect bird species and community composition. Areas occupied by prairie dogs, characterized by low percent cover of grass, high percent cover of bare soil, and low vegetation height and density, supported a breeding bird community that differed substantially from surrounding areas that lacked prairie dogs. Bird communities on colony sites had significantly greater densities of large-bodied carnivores (Burrowing Owls [Athenecunicularia], Mountain Plovers, [Charadriusmontanus], and Killdeer [Charadriusvociferus]) and omnivores consisting of Horned Larks (Eremophila alpestris) and McCown's Longspurs (Rhynchophanes mccownii) than bird communities off colony sites. Bird communities off colony sites were dominated by small-bodied insectivorous sparrows (Ammodramus spp.) and omnivorous Lark Buntings (Calamospiza melanocorys), Vesper Sparrows (Pooecetes gramineus), and Lark Sparrows (Chondestes grammacus). Densities of 3 species of conservation concern and 1 game species were significantly higher on colony sites than off colony sites, and the strength of prairie dog effects was consistent across the northern Great Plains. Vegetation modification by prairie dogs sustains a diverse suite of bird species in these grasslands. Collectively, our findings and those from previous studies show that areas in the North American Great Plains with prairie dog colonies support higher densities of at least 9 vertebrate species than sites without colonies. Prairie dogs affect habitat for these species through multiple pathways, including creation of belowground refugia, supply of prey for specialized predators, modification of vegetation structure within colonies, and increased landscape heterogeneity.Original Abstract: Asociaciones de Comunidades de Aves de Pastizales con Perros de la Pradera en la Gran Llanura de Norte America Los herbivoros excavadores coloniales pueden modificar la estructura de la vegetacion, crear refugios subterraneos y generar heterogeneidad en el paisaje, por lo tanto afectan la distribucion y abundancia de especies asociadas. Los perros de la pradera (Cynomys ludovicianus) son una de esas especies, y pueden afectar significativamente la abundancia y composicion de comunidades de aves de pastizales. Examinamos como afectan las colonias de perros de la pradera a las especies de aves y la composicion de la comunidad en la Gran Llanura de Norte America. Las areas ocupadas por perros de la pradera, caracterizadas por un bajo porcentaje de cobertura de pasto, alto porcentaje de cobertura de suelo desnudo y baja altura y densidad de la vegetacion, soportaban una comunidad de aves que difirio sustancialmente en areas que no tenian perros de la pradera. Las comunidades de aves en sitios con colonias tuvieron significativamente mayores densidades de carnivoros de talla grande (Athene cunicularia,Charadrius montanusyCharadrius vociferus) y omnivoros (Eremophila alpestrisyRhynchophanes mccownii) que las comunidades de aves en sitios sin colonias. Las comunidades de aves en sitios sin colonias fueron dominadas por gorriones insectivoros de talla pequena (Ammodramus spp.) y omnivoros (Calamospiza melanocorys,Pooecetes gramineusyChondestes grammacus). Las densidades de 3 especies de preocupacion para la conservacion y una especie cinegetica fueron significativamente mayores en los sitios con colonias, y la fuerza de los efectos de los perros de la pradera fue consistente en el norte de Gran Llanura. La modificacion de la vegetacion por los perros de la pradera sostiene a un conjunto diverso de especies de aves estos pastizales. Colectivamente, nuestros resultados y los de estudios previos muestran que las areas con colonias de perros de la pradera en la Gran Llanura de Norte America soportan densidades mas altas de por lo menos 9 especies de vertebrados que en los sitios sin colonias. Los perros de la pradera afectan el habitat de esas especies por diferentes vias, incluyendo la creacion de refugios subterraneos, proveyendo presas para depredadores especializados, modificando la estructura de vegetacion en las colonias e incrementando la heterogeneidad del paisaje.

Sensitive and high-throughput serology-based detection methods are crucial for the management of TriMV and germplasm screening in wheat breeding programs. In this study, TriMV coat protein (CP) was expressed in Escherichia coli, and polyclonal antibodies were generated against purified soluble native form recombinant CP (rCP) in rabbits. Specificity and sensitivity of resulting antibodies were tested in Western immuno-blot and enzyme-linked immunosorbent assays (ELISA). In direct antigen coating (DAC)-ELISA, antibodies reacted specifically, beyond 1:20,000 dilution with TriMV in crude sap, but not with healthy extracts, and antiserum at a 1:10,000 dilution detected TriMV in crude sap up to 1:4860 dilution. Notably, rabbit anti-TriMV IgG and anti-TriMV IgG-alkaline phosphatase conjugate reacted positively with native virions in crude sap in a double antibody sandwich-ELISA, suggesting that these antibodies can be used as coating antibodies which is crucial for any 'sandwich' type of assays. Finally, the recombinant antibodies reacted positively in ELISA with representative TriMV isolates collected from fields, suggesting that antibodies generated against rCP can be used for sensitive, large-scale, and broad-spectrum detection of TriMV.

Screening AMT transformants identified two mutants showing significantly reduced virulence. The mutants showed growth rate, sclerotial formation, and oxalate production similar to that of the wild type. The mutation was due to a single T-DNA insertion at 212 bp downstream of the Cu/Zn superoxide dismutase (SOD) gene (SsSOD1, SS1G_00699). Expression levels of SsSOD1 were significantly increased under oxidative stresses or during plant infection in the wild-type strain but could not be detected in the mutant. SsSOD1 functionally complemented the Cu/Zn SOD gene in a Delta sod1 Saccharomyces cerevisiae mutant. The SOD mutant had increased sensitivity to heavy metal toxicity and oxidative stress in culture and reduced ability to detoxify superoxide in infected leaves. The mutant also had reduced expression levels of other known pathogenicity genes such as endo-polygalacturanases sspg1 and sspg3. The functions of SsSODl were further confirmed by SsSODl-deletion mutation. Like the AMT insertion mutant, the SsSOD1-deletion mutant exhibited normal growth rate, sclerotial formation, oxalate production, increased sensitivity to metal and oxidative stress, and reduced virulence. These results suggest that SsSOD1, while not being required for saprophytic growth and completion of the life cycle, plays critical roles in detoxification of reactive oxygen species during host-pathogen interactions and is an important virulence factor of Sclerotinia sclerotiorum.

To sustain agricultural production ot food, fiber, feed, and fuel for the world population, agriculture requires water and nutrient inputs, which can impair water resources by decreasing water quality and availability. Both are concerns in the agricultural region of the Lower Mississippi River Basin (LMRB) and specifically in the state of Arkansas, where production of rice, cotton, soybean, and poultry are critical to the states economy. Water quality issues are related to excess nutrients running off of fields that subsequently influence local and regional water bodies (Carpenter et al. 1998). Water quantity issues are related to declines in ground-water caused by withdrawal rates that are greater than recharge rates. Conservation practices targeted at improving water resources and promoted through the Mississippi River Basin Healthy Watersheds Initiative (MRBI) are supported by USDA Natural Resources Conservation Service (USDA NRCS) and include a component dedicated to monitoring the water resources impact of these practices. A statewide monitoring network designed to collect water quality and water quantity data was established in 2010 in Arkansas. The network is made up of approximately 30 monitoring sites on 12 separate farms where rice, soybean, cotton, corn, poultry, and beef are produced (figure 1). The network is described in this article in detail along with targeted conservation practices. Programs and entities that supported the establishment and ongoing infrastructure of the statewide network are also described.

The enzyme (RuFae2) was identified as a type C feruloyl esterase. The RuFae2 alone released ferulic acid from rice bran, wheat bran, wheat-insoluble arabinoxylan, corn fiber, switchgrass, and corn bran in the order of decreasing activity. Using a saturating amount of RuFae2 for 100 mg substrate, a maximum of 18.7 and 80.0 mu g FA was released from 100 mg corn fiber and wheat-insoluble arabinoxylan, respectively. Addition of GH10 endoxylanase (EX) synergistically increased the release of FA with the highest level of 6.7-fold for wheat bran. The synergistic effect of adding GH11 EX was significantly smaller with all the substrates tested. The difference in the effect of the two EXs was further analyzed by comparing the rate in the release of FA with increasing EX concentration using wheat-insoluble arabinoxylan as the substrate.

The effects of these treatments on wildlife habitat, however, have received limited attention. The fisher (Martes pennanti) is a species of concern in California and is vulnerable to fuels treatments due to its association with dense forests and use of large and old trees as resting sites. We evaluated the effect of fuels treatments by estimating predicted resting and foraging habitat at two sites in the Sierra Nevada that are part of the national Fire and Fire Surrogate Study. One site included three treatments (mechanical harvest, prescribed fire, and mechanical harvest plus prescribed fire) and the other included early and late-season prescribed fire; both sites included control treatments. We sampled vegetation before and after treatment application to estimate variables that were included in resource selection probability functions. Predicted resting habitat was significantly lower for mechanical plus fire treatments, but the control did not differ from the fire only or the mechanical only treatment. Late, but not early, season burns had significant impact on predicted resting habitat. Reductions in canopy cover affected predicted resting habitat directly. Fisher foraging habitat, unlike resting habitat was unaffected by treatments at either site. Within a stand, a number of management actions can mitigate the potentially negative short-term effects of fuels treatments on fisher habitat. Evaluating the effects of fuels management at the resting site, home range and landscape scales will be necessary to administer a treatment program that can address fuel accumulation while also restoring and maintaining fisher habitat.

DO - http://dx.doi.org/10.1016/j.foreco.2012.12.035 ER - TY - JOUR T1 - Modeling below-ground biomass to improve sustainable management of Actaea racemosa, a globally important medicinal forest product AN - 1323258753; 17802494 AB - Non-timber forest products, particularly herbaceous understory plants, support a multi-billion dollar industry and are extracted from forests worldwide for their therapeutic value. Tens of thousands of kilograms of rhizomes and roots of Actaea racemosa L., a native Appalachian forest perennial, are harvested every year and used for the treatment of menopausal conditions. Sustainable management of this and other wild-harvested non-timber forest products requires the ability to effectively and reliably inventory marketable plant components. However, few methods exist to estimate below-ground biomass (rhizomes and roots) based on above-ground metrics. To estimate the relationship of above-ground vegetation components to below-ground biomass, data from a long-term sustainable harvest study of A. racemosa was used to develop a predictive model for rhizome mass. Over 1000 plants were extracted from two sites in the Central Appalachian Mountains of Virginia. Measurements of plant height and canopy dimensions were matched with corresponding green weights of rhizomes and roots. A multi-staged process was used to fit a mixed effects model. A random effects structure was selected using Akaike's Information Criterion, while the fixed effects structure was simplified through backward selection using likelihood ratio tests. Over 500 plants were harvested from three neighboring sites to evaluate the effectiveness of the model in predicting below-ground biomass based on above-ground metrics. The relationships between above and below-ground biomass of plants from the sustainability study sites and the validation study sites were similar, indicating effectiveness of the model. Predicted values for the validation data were, on average, slightly larger than the observed values, indicating a small bias. The 95% prediction intervals computed from the model, however, covered the true values more than 95% of the time. This study demonstrates that estimating marketable rhizome biomass of native medicinal plants is feasible at a stand level. The model will serve as a valuable tool for inventorying forest products, allowing estimation of below-ground biomass based on above-ground metrics. Use of this tool will aid in developing effective inventory and management strategies for wild-harvested medicinal plants. Adaptation of this model to other species will encourage efforts toward sustainable use of non-timber forest products worldwide.

AN - 1319617826; 23462167 AB - Pima cotton production is increasing in the United States, but Pima cottonseed generally contains higher concentrations of the antinutritive pigment gossypol than conventional upland cottonseed. Heating promotes the reaction of gossypol with protein, reducing gossypol absorption and toxicity. The objective of this study was to assess the nutritional value for dairy cattle of Pima cottonseed cake (PCSC) that was heated and oil largely removed by an experimental extrusion process, compared with upland cottonseed (UCS) and Pima cottonseed (PCS). The PCS had greater crude protein (CP) and ether extract, less neutral detergent fiber (NDF) and acid detergent fiber (ADF), similar total gossypol, but higher (-)-gossypol isomer compared with UCS. Extrusion reduced lipid content by 73%, increased concentrations of CP, NDF, and ADF, and reduced total gossypol, (+)-gossypol, and (-)-gossypol in PCSC versus PCS. Forty lactating Holsteins (8 with ruminal cannulas) were blocked by days in milk into 5 squares in a replicated, incomplete 8 × 8 Latin square, and were fed diets containing, on a dry matter (DM) basis, 30% alfalfa silage, 31% corn silage, 21 to 25% high-moisture corn, and about 15% CP. Diets were fed as total mixed rations for ad libitum intake. Supplemental CP was from (1) solvent soybean meal (SSBM) only or 50% from SSBM plus 50% from (2) UCS, (3) PCS, (4) PCSC, (5) UCS plus PCS, and (6) UCS plus PCSC, or (7) 50% from expeller soybean meal (ESBM) plus 50% from PCS, and (8) 50% from ESBM plus 50% from PCSC. Periods were 4 wk long (total of 16 wk); production data were collected over the last 2 wk and blood and ruminal samples were taken on d 28 of each period. Data were analyzed using Proc Mixed of SAS (SAS Institute Inc., Cary, NC). Diet affected dry matter intake, with greatest intake on diet 6 and lowest intake on diets 1 and 3. The highest milk fat content was observed on diet 5 and the greatest fat yield on diet 7; fat content and yield were lowest on diet 1 (soybean meal control). Milk fat secretion was proportional to dietary fat content, indicating that cottonseed oil was used effectively for milk fat synthesis. We observed a trend for an effect on milk protein yield with the greatest protein secretion occurring on diet 7. Milk urea was lowest on diets 3, 7, and 8. Ruminal concentrations of branched-chain volatile fatty acids were lower, or tended to be lower, when PCSC replaced either UCS or PCS in the diet, suggesting reduced degradation and increased escape of PCSC protein. Among cottonseed-containing diets, total gossypol intake was lowest on PCSC, intermediate on PCS, and highest on UCS. Total gossypol and both (+)- and (-)-isomers of gossypol were higher in blood plasma on PCS and lower on PCSC than on the corresponding diets containing UCS, indicating that the extrusion process reduced gossypol absorption. In this trial, production on diets supplemented with UCS, PCS, or PCSC was comparable to that on diets containing soybean meal. Copyright © 2013 American Dairy Science Association.

Collections of P. triticina from infected wheat leaves were obtained from the main wheat production zones of Turkey in 2009 and 2010. A total of 104 single uredinial isolates were tested for virulence on 20 lines of Thatcher wheat that differ for single leaf rust resistance genes. Forty-four different virulence phenotypes were identified over both years. Four phenotypes were found in both years. Phenotype FHPTQ found in 2009, with virulence to genes Lr2c, Lr3, Lr16, Lr26, Lr3ka, Lr17a, Lr30, LrB, Lr10, Lr14a, Lr18, Lr3bg, and Lr14b, was the most common phenotype at 15.4 % of the total isolates. Forty-three winter and spring wheat cultivars from Turkey were tested as seedlings with 13 different P. triticina virulence phenotypes from Canada, the US and Turkey. The infection types on the cultivars were compared with infection types on the Thatcher near isogenic lines to postulate the presence of seedling leaf rust resistance genes in the cultivars. Resistance genes Lr1, Lr3a, Lr10, Lr14a, Lr17a, Lr20, Lr23, and Lr26 were postulated to be present in the Turkish wheat cultivars. DNA of the wheat cultivars was tested with PCR markers to determine the presence of the adult plant resistance genes Lr34 and Lr37. Marker data indicated the presence of Lr34 in 20 cultivars and Lr37 in three cultivars. Field plot evaluations of the wheat cultivars indicated that no single Lr gene conditioned highly effective leaf rust resistance. Resistant cultivars varied for combinations of seedling and adult plant resistance genes.

AN - 1316379310; 23271125 AB - Phytoene desaturase is the key enzyme involved in the biosynthesis pathway of lutein. The unicellular microalga, Chlorella protothecoides CS-41, had been selected for the heterotrophic production of high concentrations of lutein. In this study, a cDNA copy of the pds gene from C. protothecoides was obtained using the rapid amplification of cDNA ends (RACE) technique. Phylogenetic analysis of the deduced amino acid sequence revealed that the phytoene desaturases derived from the algal family. Expression of the pds gene in Escherichia coli produced a single protein of 61 kDa. The PDS activity of the expressed protein was confirmed by the production of ζ-carotene as the result from the action of the enzyme's desaturation activity, which was identified by high-performance liquid chromatography and heterologous complementation analysis. Using random and site-directed mutagenesis, a single amino acid mutation (N144D) was identified and confirmed. This mutant encodes an inactive enzyme, which implies that amino acid 144 is crutial to the activity of the PDS enzyme.

The Biocontrol GDS registered and DuPont Qualicon BAX registered -RT rapid detection systems are two commercial tests based on real-time PCR amplification with potential applications for quantification of specific E. coliO157:H7 gene targets in enriched meat samples. However, there are arguments surrounding the use of these tests to predict pre-enrichment concentrations of E. coliO157:H7, as well as arguments pertaining to the influence of non-viable cells causing false positive results. The present study attempts to illustrate the effects of different bacterial physiologic states and the presence of non-viable cells on the ability of these systems to accurately measure contamination levels of E. coliO157:H7 in ground beef. While the PCR threshold cycle (CT) values of these assays showed a direct correlation with the number of bacteria present in pure cultures, this was not the case for ground beef samples spiked with various levels of injured or healthy cells. Furthermore, comparison of post-enrichment cell densities of bacteria did not correlate with injured or healthy cell numbers inoculated before enrichment process. Ground beef samples spiked with injured or healthy cells at different doses could not be distinguished by CT values from either assay. In addition, the contribution of nonviable cells in generating positive real-time PCR signals was investigated using both assays on pre-enriched and post-enriched beef samples, but only if inoculated at levels of 106 cells/sample or higher, which are levels not typically seen in ground beef.

The surface acidic functional groups were determined quantitatively by the Boehm Titration method. The adsorptive properties of heavy metals, Zn2+ and Cu2+ onto the biochars and the activated carbons were investigated by the adsorption isotherms and SEM images, and correlated with the surface properties. ATR-FTIR and GC techniques were used to analyze the adsorptive behavior of phenol onto the biochars and activated carbons, and the results demonstrated that phenol adsorption capability is directly proportional to the micropore surface area as well as the combined level of the accessible carboxylic and lactonic groups. The relative adsorption capacity with respect to the biomass precursor follows the order: SW > HW > SG.

Effects of three sources of nutrient (inorganic only, organic + inorganic combination, and organic only) and four utilization regimes (unharvested, low and high grazing pressure, and hayed) were evaluated on botanical composition, residual forage mass, and forage production during seven years of management on tall fescue (Lolium arundinaceum, a cool-season C3 grass) overseeded into existing bermudagrass (Cynodon dactylon, a warm-season C4 grass) sod in Georgia. Nutrient source had few major impacts on responses, except for greater hay yield with organic fertilization (broiler litter) than with organic + inorganic and inorganic only fertilization. Botanical composition of grazed pastures shifted with time from initial dominance with bermudagrass ( similar to 50% basal area) to mixed composition of tall fescue (60%)/bermudagrass (36%) under low grazing pressure and tall fescue (45%)/bermudagrass (48%) under high grazing pressure. To maintain optimum botanical composition and productivity for year-round sustainable grazing, forage mass needs to be balanced within a maximum threshold to avoid deterioration of forage quality and a minimum threshold to avoid environmental degradation.

AN - 1323820511; 17841238 AB - The meadow fritillary (Boloria bellona Fabricius, 1775) is a common species of Nymphalidae found throughout Canada and the north-central and northeastern United States where it lives in open wet-grassy areas such as prairies, meadows, pastures and fields (Opler 1998; Brock & Kaufmann 2006; Schlicht et al. 2007). In the state of Iowa it is also known to inhabit fens (Schlicht et al. 2007), which are diverse open wetlands characterized by continuous surface to near surface saturation by groundwater, organic soil and non-emergent graminoid vegetation (Thompson et al. 1992; Amon et al. 2002). Nectar habits include many species of flowers, with a preference for members of the Asteraceae (Opler & Krizek 1984).

A basic assumption in this research is that plant delta super(15)N reflects the delta super(15)N of the N source. Recent evidence suggests that plants may fractionate on uptake, transport, or transformation of N. If the dominant source of plant N is via roots, a difference in delta super(15)N by tissue type would suggest fractionation on transport and assimilation of N. In order to evaluate differences between species and plant parts, we measured delta super(15)N in root, stem, and leaf tissues of individual sugar maple (Acer saccharum; SM) and American beech (Fagus grandifolia; BE) plants ranging in age from germinants to mature trees at the Hubbard Brook Experimental Forest, New Hampshire (USA). For SM, root delta super(15)N > stem delta super(15)N > leaf delta super(15)N; for BE seedlings, root delta super(15)N > stem delta super(15)N and root delta super(15)N > leaf delta super(15)N. These differences suggest that fractionation occurs during plant transport and assimilation of N. Beech delta super(15)N (root, stem, and leaf) was consistently higher than SM delta super(15)N for 1-7 year-old seedlings. At one site, we found no differences with age in foliar delta super(15)N (range: 4.1-4.8 ppt) for seedlings, saplings, and trees which suggests that it may be possible to compare foliar delta super(15)N of plants of different ages at some sites. However, at another site, foliar and root delta super(15)N were higher for trees than 1-2 year-old seedlings. This study suggests that physiological differences in N assimilation and transport processes that differ by species likely control plant delta super(15)N.

High and Low Temperature Pyrolyzed Biochars AN - 1671520437; 17684268 AB - Inorganic elements in biomass feedstocks can influence thermochemical reactions as well as the resultant char's elemental, compositional, and thermal characteristics. Chars were produced using slow pyrolysis under low ( less than or equal to 400 degree C) and high ( greater than or equal to 500 degree C) temperature regimes from sugarcane bagasse, peanut hulls, pecan shell, pine chips, poultry litter, and switchgrass. The chars and raw feedstocks were characterized for their elemental, structural, and thermal properties to ascertain the implications of feedstock selection and pyrolysis temperatures on these properties. Char mass yields from the six feedstocks ranged between 28% and 78% by weight while carbon yields ranged between 44% and 89%. In both instances, lower yields were obtained with increasing pyrolysis temperature. Higher pyrolysis temperatures ( greater than or equal to 500 degree C) resulted in more neutral to alkaline chars possessing greater ash contents and increased aromatic character with narrow O/C and H/C ratios. A significant exponential curve response (r super(2)=0.87, P30 MJ kg super(-1). The chars' HHV values inversely correlated to their total ash and Cl content. Lignocelluloses chars had better thermal characteristics and lower ash quality concerns implying suitable service in thermal energy production. In contrast, poultry litter char had greater ash contents, medium HHV values, and contained corrosive inorganic elements, which rendered it problematic as a feedstock for thermal energy generation.

It may be more monetarily convenient if an alternate amendment was available that could deliver similar soil enhancements. We compared two switchgrass biochars pyrolyzed at 250 and 500 degree C with raw switchgrass (uncharred) on moisture storage and bulk density changes in a Norfolk loamy sand (fine-loamy, kaolinitic, thermic Typic Kandiudult). Amendments were mixed into triplicate pots at 20 g/kg along with untreated controls. Soils were laboratory incubated at 10% moisture content (w/w) for 118 days, and the pots were irrigated three times with 1.3 pore volumes of deionized water every 30 days. Soil bulk densities were recorded before each irrigation event. Assessment of alterations in soil water storage was examined through cumulative water evaporative losses from incubation day 0 to day 33 and by monitoring soil water contents for 13 consecutive days past each irrigation event. Rankings of soil water evaporative losses were as follows: uncharred switchgrass less than or equal to switchgrass (500 degree C) less than or equal to switchgrass (250 degree C) < control. After the first irrigation event, uncharred switchgrass amendment significantly increased moisture storage compared with soil treated with biochar and the control. While all amendments increased water storage relative to the control, uncharred switchgrass delivered equivalent, if not slightly better, moisture storage improvements compared with the two switchgrass biochars. Uncharred switchgrass would likely not be as effective over the long term (years to decades) as pyrolyzed biochars, due to greater degradation of uncharred material.

Forty-six percent of A. flavus, isolated from maize kernels collected in 5 districts of northern Italy between 2003 and 2010, were unable to produce detectable levels of aflatoxins. The genetic diversity of the population was assessed by analysis of vegetative compatibility groups (VCGs) and presence or absence of several aflatoxin biosynthesis genes. Forty-eight VCGs were identified through complementation between nitrate non-utilizing mutants. Twenty-five VCGs contained only atoxigenic isolates, and the remaining 23 only aflatoxin producers. Members of the largest atoxigenic VCG (IT6) were found in 4 of the 5 districts sampled. Six deletion patterns of genes in the aflatoxin biosynthesis gene cluster were detected. No deletions in the cluster were detected for twelve atoxigenic isolates and 10 had the entire cluster deleted. One isolate had a deletion pattern only seen once before in Nigeria. The basis for initial selection of endemic atoxigenic strains of A. flavus for biological control of aflatoxin contamination of maize in Italy is provided.

The objective of this study was to inactivate Escherichia coli using a UV irradiator that centrifugally formed a thin film of LEW on the inside of a rotating cylinder. The LEW was inoculated with E. coli K12 to approximately 8 log cfu/ml and was processed at the following conditions: UV intensity 1.5 to 9.0 mW/cm super(2); cylinder rotational speed 450 to 750 RPM, cylinder inclination angle 15 degree to 45 degree , and flow rate 300 to 900 ml/min, and treatment time 1.1 to 3.2 s. Appropriate dilutions of the samples were pourplated with tryptic soy agar (TSA). Sublethal injury was determined using TSA + 4% NaCl. The regrowth of surviving E. coli during refrigerated storage for 28 days was investigated. The electrical energy of the UV process was also determined. The results demonstrated that UV processing of LEW at a dose of 29 mJ/cm super(2) at 10 degree C reduced E. coli by 5 log cfu/ml. Inactivation significantly increased with increasing UV dose and decreasing flow rate. The results at cylinder inclination angles of 30 degree and 45 degree were similar and were significantly better than those at 15 degree . The cylinder rotational speed had no significant effect on inactivation. The occurrence of sublethal injury was detected. Storage of UV processed LEW at 4 degree and 10 degree C for 21 days further reduced the population of E. coli to approximately 1 log cfu/ml where it remained for an additional 7 days. The UV energy applied to the LEW to obtain a 5 log reduction of E. coli was 3.9 J/ml. These results suggest that LEW may be efficiently pasteurized, albeit at low flow rates, using a nonthermal UV device that centrifugally forms a thin film.

This requires collection of extensive and accurate hydrologic and sediment data sets. A supercritical flume with a total load traversing slot sediment sampler used on several sites at the Walnut Gulch Experimental Watershed (WGEW) near Tombstone, AZ has proven to be a reliable way to measure flow and sediment discharge from small watersheds. However, it requires installation of a costly structure that is only suitable for relatively small flows. A more commonly used method based on ease of installation and expense is the pump sampler. One example of this is a set of instrumentation developed by the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO), in which the pump sediment sampler is part of an in-channel, fully automated system for measuring water velocity, depth, turbidity and collecting runoff samples. A 3.7ha arid watershed at WGEW was instrumented with both systems and hydrologic and sediment data were collected and compared during a 2year period. Total sediment yield for the entire period measured by the CSIRO pump sampler (11.6tha super(-1)) was similar to that by traversing slot sampler (11.5tha super(-1)). The pump sampler accurately estimated the amount of fine (0.5mm) sediment fractions. Median sediment diameter of samples collected by traversing slot and pump sampler were 0.32 and 0.22mm, respectively. This study outlines the benefits and limitations of the pump sampler based system for monitoring sediment concentration and yield in high-energy headwater catchments, and makes recommendations for improvement of its performance.

The transformational initiatives involved: (1) centralizing and consolidating network services from 48 locations; (2) standardizing survey metadata and integrating survey data into easily accessible databases across all surveys; and (3) consolidating and generalizing survey applications for the agency's diverse survey program. The three architectural transformations will be described as well as initial efforts to consolidate and standardize survey operations across the agency. Adapted from the source document.

Conservationists are concerned about the far-reaching environmental impacts of housing development, particularly in rural areas. We use clustering analysis to examine the pattern and distribution of housing development since 1940 in and around the Northern Forest, a heavily forested region with high amenity and recreation use in the Northeastern United States. We find that both proximity to urban areas and an abundance of natural amenities are associated with housing growth at the neighborhood level in this region. In the 1970s, counterurbanization led to higher rates of growth across rural areas. The Northern Forest now has extensive interface between forest vegetation and residential development, which has the potential to profoundly alter the ecological and social benefits of these forests.

(Solms). This species exhibits significant wing dimorphism whereby fully winged adults (macropters) are capable of flight while those with reduced wings (brachtypters) are not. The wing form is determined by a developmental switch triggered by environmental factors including crowding, host plant quality, temperature, and photoperiod. This study examined the influences of insect density and host plant quality on M. scutellaris wing dimorphism, development, and biomass as well as their effects on E. crassipes. Two experiments exposed a single generation of M. scutellaris to lower and higher densities of conspecifics on low and high quality plants. The first experiment involved transferring second instars to test plants at loads of 50, 5, or 1 g of fresh weight plant biomass per nymph, which resulted in mean densities of 2, 15, and 69 nymphs, respectively, on both low and high quality plants. A second experiment exposed test plants to 2, 4, or 20 M. scutellaris adults for 7 days and allowed their progeny to develop into adults which ultimately produced densities of 0, 56, and 352 F1 adults, respectively, per low and high quality plants. No macropterous adults were produced in any treatment combination in either experiment. Several plant variables were affected by insect densities and plant quality including the mean relative growth rate, the change in leaf number, and the percentage of dead leaves on a plant. Megamelus scutellaris appeared to have a relatively high density threshold for macroptery within the range of host quality used in these studies. This may promote more brachyptery which, in turn, may increase the chances of this insect reaching damaging densities in field populations of E. crassipes.

In an effort to establish populations for classical biological control of this weed, the weevil, Cyrtobagous salviniae Calder and Sands, was released at multiple sites across Louisiana. Many of the release sites were lost due to a variety of ecological and anthropological disturbances. In 2008, C. salviniae was found to have successfully overwintered on S. minima in Gramercy, Louisiana. Attack by Cyrtobagous salviniae significantly increased the number of damaged terminal buds and decreased the fresh weight biomass of S. minima.

AN - 1372056888; 18131376 AB - The semi-aquatic weevil Bagous hydrillae was released during 1991-1996 at 19 sites in 4 states in attempts to control the aquatic weed hydrilla, Hydrilla verticillata. Fourteen of the sites were in Florida, 2 each in Texas and Georgia and one site in Alabama. Over 320,000 adult weevils were included in these releases. Despite the fact that a few adults were recovered as late as 4.5 yr post-release, presence of permanent, self-perpetuating populations was never confirmed. Then, during 2009 adult B. hydrillae were collected in southern Louisiana, at least 580 km from the nearest release site and 13 yr after attempts to establish this insect had terminated. This suggests that earlier recoveries were indicative of successful establishment and that this weevil species has persisted and dispersed widely in the southeastern USA. Nonetheless, there is no evidence that B. hydrillae has had a suppressive effect on hydrilla.

Data recorded included time in the start box, time in the T-maze, exit arm chosen to leave the T-maze, and return alley. Right and left arms of the T-maze were chosen 65.7% and 34.3% of the time, respectively, while right and left return alleys were chosen 32.4% and 67.6%, respectively. Exit arm and return alley were not independently chosen (p<.0001), with observed counts being higher than expected under independence when ewes made the same choice for exit and alley (RR or LL turn patterns) and being lower than expected for alternating choices (RL or LR). Out of the 309 ewes, 28.2% and 30.1% chose RR and LL turn patterns, respectively, while 37.5% chose the RL turn pattern, but only 13 (4.2%) chose the LR turning pattern. Overall, ewes that initially turned right when presented a second turning opportunity had a slight preference to alternate their turning direction, while ewes that initially turned left tended to continue turning left when given another chance to turn. Exit arm and return alley laterality was not related (a=.05) to time of day the test was administered, ewe's age or genetics, most recent liveweight, or most recent shorn fleece weight. The mean time spent in the start box (21 s) was not related to exit arm (p=.947) or return alley (p=.779). Mean time (15 s) spent in the T-maze was not related to exit arm (p =.086) or return alley (p =.952). More research will be required to understand sheep turning laterality and how it can impact working facilities and research equipment. Adapted from the source document.

Compositionally, this stand had considerable arboreal richness, with 26 different tree species greater than or equal to 9 cm in diameter. Loblolly pine (Pinus taeda) contributed 42% of the stand's 37.1 m2/ha of basal area; the remaining fraction included baldcypress (Taxodium distichum) and 24 hardwood species (no other single taxon exceeded 12%). Only a limited volume (15.2 m3/ha) of dead wood was encountered. The large size of the dominant conifers and abundance of high wood density hardwoods at Hyatt's Woods yielded a considerable quantity of biomass-at 317 Mg/ha, few stands in the region have more. With all species combined, tree stem location exhibited a random spatial pattern, but this changed when individual species were considered. For example, loblolly pine tended to be clustered on the higher portions of this relatively flat site, while white oak (Quercus alba) was well distributed across Hyatt's Woods, and baldcypress was associated with two abandoned stream channels. Unmanaged streamside forests in southeastern Arkansas usually contain high levels of arboreal diversity and biomass, and sometimes possess biological legacies that can date back centuries. These stands retain important structural and ecosystem service components in an otherwise increasingly fragmented and intensively managed landscape.

Seasonal size differences in reproductive structures suggested that maximum spermatogenic activity occurred during the late summer, with spermatozoa transfer to the vasa deferentia occurring in the fall through spring. Maximum development of mature follicles occurred during the winter; however, follicular growth occurred year-round and was asynchronous among individuals. Courtship and mating probably occurred in late fall through early spring, with egg deposition from spring into early summer. Reproduction for females was not annual, and patterns suggested that the reproductive cycle was biennial or less frequent. In contrast, evidence indicated annual reproduction in males. Gravid females contained an average of 10 mature follicles.

We examined the influence of planting timing on germination and seedling demography of bluebunch wheatgrass (Pseudoroegneria spicata [Pursh] A. Love) in the northern Great Basin. In 2008 (year 1) and 2009 (year 2) we planted seeds monthly, September-December, in 1-m2 plots (500 seeds per plot) using a randomized block design with five replications. Germination timing was indexed using seed bags placed adjacent to 1-m2 plots and retrieved at 2-wk intervals in fall and 1-mo intervals in spring. Seedlings were marked in March-June of the year following planting; seedlings alive in July were considered initially established. Planting in September and October had up to 80% germination prior to winter, whereas December plantings germinated mainly in spring and at reduced rates (15-35%). Seeds planted in September and October emerged approximately a month earlier than November-December plantings. The percentage of germinated seeds that emerged was highest for September-October plantings but the percentage of emergent seeds surviving to the end of the first growing season was highest for later plantings. Final seedling density was lowest for November planting in year 1 and highest for September and October planting in year 2. Our data indicate that timing of and performance at critical stages of seedling development were affected by planting month. We suggest that it may be possible to use emerging technologies (e.g., seed coatings or germplasm manipulations) to produce variable chronologies of seedling development with single plantings and allow managers to exploit multiple temporal windows of opportunity for seedling establishment.

Our objectives were to evaluate freezing tolerance of germinated but nonemergent bluebunch wheatgrass seeds under laboratory conditions. We used data from a 2-yr pilot study to determine overwinter freezing temperature and duration for soils in southeastern Oregon. We then conducted two experiments to assess freezing tolerance. In experiment 1, bluebunch wheatgrass seeds were planted in control pots and compared to seeds planted at early, mid, or late postgermination stages. Pots from each treatment were placed in a grow room maintained at 12 h 40 min light/11 h 20 min dark photoperiod, with a constant temperature of 22 degree C for 30 d either immediately or following a 30-d freeze. In experiment 2, germinated bluebunch wheatgrass seeds were planted in pots that were left nonfrozen or were frozen for a specified duration prior to a 30-d period in the grow room. Emergence density and tillers.seedling-1 were quantified for both experiments. The number of days per year for freezing soil conditions in the pilot study ranged yearly from 25 to 51; maximum duration of continuous freezing was 16.5 and 11.2 d. Freezing reduced or eliminated seedling emergence at all postgermination stages (P>6 d of freezing (P=0.001). Our data indicate that freezing-associated mortality of germinated but nonemergent bluebunch wheatgrass seedlings can be extremely high and suggest that management practices to reduce prewinter germination of seeds could improve subsequent emergence and seeding success.

AN - 1348483518; 17880088 AB - Medusahead (Taeniatherum caput-medusae [L.] Nevski) is an exotic annual grass invading western rangelands. Successful revegetation of invaded-plant communities can be prohibitively expensive because it often requires iterative applications of integrated control and revegetation treatments. Prescribed burning has been used to control medusahead and prepare seedbeds for revegetation, but burning has been constrained by liability concerns and has produced widely varying results. Capitalizing on naturally occurring wildfires could reduce revegetation costs and alleviate liability concerns. Thus, our objective was to determine if early summer wildfires and fall drill seeding could be used as a treatment combination to decrease medusahead and increase perennial and native vegetation. Treatments were evaluated pretreatment and for 3 yr postfire at six sites and included 1) an early summer wildfire combined with a seeding treatment (burn and seed) and 2) a nontreated (no burn, no seed) control. Perennial grass density was 4.6- to 10.0-fold greater in the burn-and-seed treatment compared to the control in the first 3 yr posttreatment (P130 individuals.m-2 in the burn-and-seed treatment. The density of exotic annual grass is of concern because over time medusahead may displace perennial grasses and annual forbs that increased with the burn-and-seed treatment. Though not directly tested in this study, we suggest that, based on other research, the burn-and-seed treatment may need to incorporate a preemergent herbicide application to further suppress medusahead and increase the establishment of seeded vegetation. However, it appears that early summer wildfires may provide an opportunity to reduce the cost of integrated programs to revegetate medusahead-invaded plant communities.

The purpose of the current study was to use hydrothermal germination models and a soil energy and water flux model to evaluate intra- and interannual variability in seedbed microclimate relative to potential germination response of six perennial grasses and cheatgrass. We used a 44-yr weather record to parameterize a seedbed microclimate model for estimation of hourly temperature and moisture at seeding depth for a sandy loam soil type at the Orchard Field Test Site in southwestern Ada County, Idaho. Hydrothermal germination response was measured in the laboratory for two seed lots of cheatgrass (Bromus tectorum L.), four seed lots of bluebunch wheatgrass (Pseudoroegneria spicata [Pursh] Love), three seed lots of bottlebrush squirreltail (Elymus elymoides [Raf] Swezey), and one seed lot each of Sandberg bluegrass (Poa secunda J. Presl.), big squirreltail (Elymus multisetus [J.G. Smith] M.E. Jones), thickspike wheatgrass (Elymus lanceolatus [Scribn. And J.G. Smith] Gould) and Idaho fescue (Festuca idahoensis Elmer). Germination response models were developed to estimate potential germination rate for 13 subpopulations of each seed lot for every hour of the 44-yr simulation. Seedbed microclimate was assessed seasonally and for each day, month, and year, and germination rate-sum estimates integrated for a numerical index of relative site favorability for germination for each time period. The rate-sum favorability index showed a consistent pattern among seed lots for different years, and provides a relatively sensitive indicator of annual and seasonal variability in seedbed microclimate. This index could be used with field data to define minimum weather thresholds for successful establishment of alternative plant materials, in conjunction with weather forecast models for making restoration and fire-rehabilitation management decisions in the fall season, for evaluation of potential climate-change impacts on plant community trajectories, and in optimization schemes for selecting among alternative restoration/rehabilitation management scenarios.

To determine the utility and effectiveness of various perennial grass species for revegetation on varied landscapes, a meta analysis was used to evaluate the stand establishment and persistence of 18 perennial cool-season grass species in 34 field studies in the Intermountain and Great Plains regions of the United States under monoculture conditions. Combined across the 34 studies, stand establishment values ranged from 79% to 43% and stand persistence values ranged from 70% to 0%. Intermediate wheatgrass (Thinopyrum intermedium [Host] Barkworth & D. R. Dewey), tall wheatgrass (Thinopyrum ponticum [Podp.] Z.-W. Liu & R.-C. Wang), crested wheatgrass (Agropyron spp.), Siberian wheatgrass (Agropyron fragile [Roth] P. Candargy), and meadow brome (Bromus riparius Rehmann) possessed the highest stand establishment ( greater than or equal to 69%). There were no significant differences among the 12 species with the largest stand persistence values. Basin wildrye (Leymus cinereus (Scribn. & Merr.) A. Love), Altai wildrye (Leymus angustus [Trin.] Pilg.), slender wheatgrass (Elymus trachycaulus [Link] Gould ex Shinners), squirreltail (Elymus spp.), and Indian ricegrass (Achnatherum hymenoides [Roem. & Schult.] Barkworth) possessed lower stand persistence ( less than or equal to 32%) than the majority of the other species, and Indian ricegrass (0%) possessed the lowest stand persistence of any of the species. Correlations between environmental conditions and stand establishment and persistence showed mean annual study precipitation to have the most consistent, although moderate effect (r= similar to 0.40) for establishment and persistence. This relationship was shown by the relatively poor stand establishment and persistence of most species at sites receiving less than 310 mm of annual precipitation. These results will be a tool for land managers to make decisions concerning the importance of stand establishment, stand persistence, and annual precipitation for revegetation projects on disturbed sites.

The chicken provides a unique animal model to study the effects of embryonic stressors on childhood and adolescent behavior. Manipulations to the egg can be made in the absence of confounding maternal effects from treatment. Eggs were injected with 50 [micro]L of excess 5-HT (10 [micro]g/egg), 8-OH-DPAT (a 5-HT1A receptor agonist; 16 [micro]g/egg), or saline on day 0 prior to the 21 days incubation. Injections were performed at 0.5 cm below the shell. Behavior was analyzed at 9 weeks of age and again at the onset of sexual maturity (18 weeks). Hens treated with excess embryonic 5-HT exhibited significantly less aggressive behaviors at 9 weeks of age compared to both 5-HT1A agonist treated and saline hens (P < 0.05), and at 18 weeks of age compared to saline control birds only (P < 0.05). Excess embryonic 5-HT also increased fearfulness response (P < 0.05) as tested by duration of tonic immobility. Increased degree of fluctuating asymmetry at 18 weeks in 5-HT-treated birds (P < 0.05) suggests that excess 5-HT in early embryonic stages may create a developmental instability, causing phenotypic variations. These results showed that modification of the serotonergic system during early embryonic development alters its functions in mediating aggressive and fearful or anxious behaviors. Prenatal modification of the serotonergic system has long lived implications on both physiology and behavior, especially aggressive and fearful behaviors.

The high dimensionality and grouped nature of this type of data can complicate standard analysis, summarization, and visualization. The "aqp" (algorithms for quantitative pedology) package was designed to support data-driven approaches to common soils-related tasks such as visualization, aggregation, and classification of soil profile collections. In addition, we sought to advance the study of numerical soil classification by building on previously published methods within an extensible and open source framework. Functions in the aqp package have been successfully applied to studies involving several thousand soil profiles. The stable version of the aqp package is hosted by CRAN (http://cran.r-project.org/web/packages/aqp), and the development version is hosted by R-Forge (http://aqp.r-forge.r-project.org).

Wing-style sticky traps baited with polyethylene vial pheromone dispensers captured more male DWB over the first 2 months than traps baited with rubber septum pheromone dispensers. However, catches in vial-baited traps decreased considerably after the first 2 months, possibly due to the antagonistic effect of 3,5-di-tert-butyl-4-hydroxy acetophenone that diffused from the polyethylene vials. By contrast, traps baited with rubber septum dispensers captured DWB males for at least 6 months; over the last four months of the flight season, catches in traps baited with a rubber septum were greater than those in traps baited with a vial dispenser. Therefore, the rubber septum dispenser is recommended for season-long monitoring of DWB. A release-rate study, using laboratory and field-aged dispensers, demonstrated that desorption of DWB sex pheromone from polyethylene vial or rubber septum dispensers followed first order kinetics, with half-lives of 1.6 and 10.7 months, respectively. Several trap designs, including wing-and delta-style sticky traps, and white and green "bucket-style" traps, baited with rubber septum dispensers were compared in commercial apple orchards for catch of DWB. Bucket traps caught more moths when moth populations were high, because the sticky surfaces of the 1C and delta traps likely became saturated. However, among the commercially available traps tested, no particular design gave consistently higher catches. Further work is needed to explore capture mechanisms and maintenance needs of different trap types.

Infection is presumed to occur through leaves or stems, although details of the infection process and conditions that favor leaf infection are not well understood. The primary objectives of this study were to investigate the early stages of infection, including the effect of temperature or water potential on ascospore germination and subsequent growth of E. typhina, the tolerance of ascospores to desiccation, the requirement of leaf wounds for infection of orchardgrass by E. typhina, and the potential for insects to facilitate infection. Ascospores tolerated dry conditions, with at least 40% surviving 12 days under desiccation. Germination and growth of E. typhina was greatest at 25 degree C, with little to no growth at 5 and 35 degree C. Mycelial growth decreased with decreasing water potential from -0.3 to -10 MPa. Ascospore germination on leaves was predominantly hyphal at wound sites and iterative (conidiogenous) at sites without wounds. E. typhina typically entered leaves through wounds. Direct penetration was rarely observed and appeared to be associated with ascospore clusters. Germ tubes were significantly longer at sites with honeydew deposits from the bird cherry-oat aphid than at sites without honeydew. Growth of E. typhina was also observed at feeding sites of eriophyid mites, suggesting that leaf-wounding or sap-excreting insects support epiphyllous growth of E. typhina on leaves.

After storage at 2 degree C for 6 weeks, the natural incidence of postharvest gray mold was reduced by potassium sorbate, the fungicide program, or both together in a tank mixture, in 2009 and 2010. In 2011, the experiment was repeated with three chitosan products (OII-YS, Chito Plant, and Armour-Zen) added. Chitosan or fungicide treatments significantly reduced the natural incidence of postharvest gray mold among grape berries. Berries harvested from vines treated by two of the chitosan treatments or the fungicide program had fewer infections after inoculation with Botrytis cinerea conidia. None harmed berry quality and all increased endochitinase activity. Chitosan decreased berry hydrogen peroxide content. One of the chitosan formulations increased quercetin, myricetin, and resveratrol content of the berry skin. In another experiment, 'Princess Seedless' grape treated with one of several fungicides before 4 or 6 weeks of cold storage had less decay than the control. Fenhexamid was markedly superior to the other fungicides for control of both the incidence and spread of gray mold during storage.

Incidence and severity of disease symptoms were low. Two types of pustules were observed on leaves of the infected plants. One pustule type was reddish-brown in color turning brown with age, characteristic of brown rust which has been observed in Louisiana since 1979 (2). The other pustule type was orange and did not turn brown with age. Urediniospore samples from the two pustule types were collected. The morphology of the urediniospores from the reddish-brown pustules was consistent with that described for Puccinia melanocephala Syd. & Syd., the fungus that causes brown rust of sugarcane, while the morphology of the urediniospores from the orange pustules was consistent with those described for P. kuehnii E.J. Butler, the causal organism of orange rust of sugarcane (3). Telia and teliospores were not observed. The identity of the two species of Puccinia causing the brown and orange rust lesions was verified using the species-specific quantitative PCR assays (1). Two DNA samples extracted from the pustules identified as P. kuehnii were independently subjected to PCR amplification using primers Pk1F and Pk1R (1) to yield a product from the rDNA that was then bidirectionally sequenced using the same primers. The resulting 48O-nt sequences were identical to each other, and a BLAST search of GenBank revealed 100% identity to 19 previously reported isolates of P. kuehnii but not more than 89% similarity to any isolate of P. melanocephala (4). To our knowledge, this is the first report of orange rust in Louisiana. In the 4 months following the detection of orange rust, observations of the disease have been limited to Ho 05-961. Seed cane increase plots of this newly released cultivar were surveyed, and orange rust symptoms and urediniospores were detected in 17 of 38 (45%) fields. The incidence and severity of the disease remained low, and the distribution appeared to be limited to the southern portion of the Louisiana sugarcane production area.

We provide a method for selecting the sample size when testing beef trim for Escherichia coli O157:H7 that equates the averted costs of recalls and health damages from contaminated meats sold to consumers with the increased costs of testing while allowing for uncertainty about the underlying prevalence rates of contamination. Using simulations, we show that, in most cases, the optimal sample size is larger than the current sample size of 60 and, in some cases, it exceeds 120. Moreover, lots with a lower prevalence rate have a higher expected damage because contamination is more difficult to detect. Our simulations indicate that these lots have a higher optimal sampling rate. JF - Risk Analysis AU - Ferrier, Peyton M AU - Buzby, Jean C AD - Economic Research Service.

Virulence information on P. striiformis f. sp. tritici populations is important to implement effective disease control with resistant cultivars. In total, 235 P. striiformis f. sp. tritici isolates from Algeria, Australia, Canada, Chile, China, Hungary, Kenya, Nepal, Pakistan, Russia, Spain, Turkey, and Uzbekistan were tested on 20 single Yr-gene lines and the 20 wheat genotypes that are used to differentiate P. striiformis f. sp. tritici races in the United States. The 235 isolates were identified as 129 virulence patterns on the single-gene lines and 169 virulence patterns on the U.S. differentials. Virulences to YrA, Yr2, Yr6, Yr7, Yr8, Yr9, Yr17, Yr25, YrUkn, Yr28, Yr31, YrExp2, Lemhi (Yr21), Paha (YrPa1, YrPa2, YrPa3 Druchamp (Yr3a, YrD, YrDru), Produra (YrPr1, YrPr2), Stephens (Yr3a, YrS, YrSte), Lee (Yr7, Yr22, Yr23), Fielder (Yr6, Yr20), Tyee (YrTye), Tres (YrTr1, YrTr2), Express (YrExp1, YrExp2), Clement (Yr9, YrCle), and Compair (YrS, Yr19) were detected in all countries. At least 80% of the isolates were virulent on YrA, Yr2, Yr6, Yr7, Yr8, Yr17, YrUkn, Yr31, YrExp2, Yr21, Stephens (Yr3a, YrS, YrSte), Lee (Yr7, Yr22, Yr23), and Fielder (Yr6, Yr20). Virulences to Yr1, Yr9, Yr25, Yr27, Yr28, Heines VII (Yr2, YrHVII), Paha (YrPa1, YrPa2, YrPa3), Druchamp (Yr3a, YrD, YrDru), Produra (YrPr1, YrPr2), Yamhill (Yr2, Yr4a, YrYam), Tyee (YrTye), Tres (YrTr1, YrTr2), Hyak (Yr17, YrTye), Express (YrExp1, YrExp2), Clement (Yr9, YrCle), and Compair (Yr8, Yr19) were moderately frequent (>20 to <80%). Virulence to Yr10, Yr24, Yr32, YrSP, and Moro (Yr10, YrMor) was low ( divided by 20%). Virulence to Moro was absent in Algeria, Australia, Canada, Kenya, Russia, Spain, Turkey, and China, but 5% of the Chinese isolates were virulent to Yr10. None of the isolates from Algeria, Canada, China, Kenya, Russia, and Spain was virulent to Yr24; none of the isolates from Algeria, Australia, Canada, Nepal, Russia, and Spain was virulent to Yr32; none of the isolates from Australia, Canada, Chile, Hungary, Kenya, Kenya, Nepal, Pakistan, Russia, and Spain was virulent to YrSP; and none of the isolates from any country was virulent to Yr5 and Yr15. Although the frequencies of virulence factors were different, most of the P. striiformis f. sp. tritici isolates from these countries shared common virulence factors. The virulences and their frequencies and distributions should be useful in breeding stripe-rust-resistant wheat cultivars and understanding the pathogen migration and evolution.

For four generations, families from these crosses were fed the Selection Diet and selected for increased weight gain. Growth and nutrient retention were compared among H-ARS and two parental strains, the House Creek (HSC) and Fish Lake (FL) fed either a fish meal or Selection diet for 12 weeks. There was a significant effect of strain (P < 0.01), but not diet on weight gain, and a significant interaction of strain by diet (P < 0.05). The H-ARS trout gained more weight averaged across diet (991% of initial wt.) than the HC (924%) or FL trout (483%). The FL trout fed the fish meal diet gained more weight than FL trout fed the selection diet (510% vs 456%). Conversely, H-ARS trout fed the plant-based diet gained more weight than those fed the fish meal diet (1009% vs 974%). HSC trout had similar weight gain fed either diet (922% vs 926%). A significant effect of strain on protein retention (P < 0.01) was observed, along with a significant strain by diet interaction (P < 0.02). The results demonstrate that rainbow trout can be selectively improved to grow on a plant-based diet.

We optimize line intercept sampling and compare estimation methods for assessing feral swine damage within fragile wetland ecosystems in Florida. Sensitive wetland sites, and the swine damage within them, were mapped using GPS technology. Evenly spaced parallel transect lines were simulated across a digital map of each site. The length of each transect and total swine damage under each transect were measured and percent swine damage within each site was estimated by two methods. The total length method (TLM) combined all transects as a single long transect, dividing the sum of all damage lengths across all transects by the combined length of all transect lines. The equal weight method (EWM) calculated the damage proportion for each transect line and averaged these proportions across all transects. Estimation was evaluated using transect spacings of 1, 3, 5, 10, 15, and 20 m. Based on relative root mean squared error and relative bias measures, the TLM produced higher quality estimates than EWM at all transect spacings. Estimation quality decreased as transect spacing increased, especially for TLM. Estimation quality also increased as the true proportion of swine damage increased. Diminishing improvements in estimation quality as transect spacings decreased suggested 5 m as an optimal tradeoff between estimation quality and labor. An inter-transect spacing of 5 m with TLM estimation appeared an optimal starting point when designing a plan for estimating swine damage, with practical, logistical, economic considerations determining final design details.

We identified genes expressed by Pf-5 under the control of two global regulators (GacA and RpoS) known to influence biological control and secondary metabolism. Transcript levels of 897 genes, including many with unknown functions as well as those for biofilm formation, cyclic diguanylate (c-di-GMP) signalling, iron homeostasis and secondary metabolism, were influenced by one or both regulators, providing evidence for expression of these genes by Pf-5 on seed surfaces. Comparison of the GacA and RpoS transcriptomes defined for Pf-5 grown on seed versus in broth culture overlapped, but most genes were regulated by GacA or RpoS under only one condition, likely due to differing levels of expression in the two conditions. We quantified secondary metabolites produced by Pf-5 and gacA and rpoS mutants on seed and in culture, and found that production profiles corresponded generally with biosynthetic gene expression profiles. Future studies evaluating biological control mechanisms can now focus on genes expressed by Pf-5 on seed surfaces, the habitat where the bacterium interacts with seed-infecting pathogens to suppress seedling diseases.

Within the context of global climate change, developing techniques to monitor tree range dynamics as affected by natural disturbances may enable mitigation/adaptation of projected impacts. Using a forest inventory across the eastern U.S., the northern range margins of tree distributions were examined by comparing differences in the 95th percentile locations of seedlings to adults (i.e., trees) by 0.5 degree longitudinal bands over 5-years and by levels of disturbance (i.e., canopy gap formation). Our results suggest that the monitoring of tree range dynamics is complicated by the limits of forest inventory data across varying spatial/temporal scales and the diversity of tree species/environments in the eastern U.S. The vast majority of tree and seedling latitudinal comparisons across measurement periods and levels of disturbance in the study were not statistically different from zero (53 out of 60 comparisons). A potential skewing of ranges towards a northern limit was suggested by the stability of northern margins of tree ranges found in this study and shifts in mean locations identified in previous work. Only a partial influence of disturbances on tree range dynamics during the course of the 5-years was found in this study. The results of this study underscore the importance of continued examination of the role of disturbance in tree range dynamics and refined range monitoring techniques given future forest extent and biodiversity implications.

Carriere) and Carolina hemlock (Tsuga caroliniana Engelm.). Hemlock is a "foundation species" due to its strong influence on ecosystem structure and function, especially in riparian areas. HWA management involves the integrated use of multiple approaches including chemical control, biological control, cultural treatments, host resistance, and host gene conservation. Despite extensive control efforts, large areas in the eastern US, but especially in the southern Appalachian region, have experienced extensive hemlock mortality. Most of the short-term impacts of HWA induced mortality on ecosystem structure and function are localized and small; however, long-term impacts such as large pulses of woody debris and changes in species composition that impact structure and function could be significant. Using a decision analysis framework, land managers should begin to strategically implement land management decisions to address observed short-term impacts and plan and manage for projected longer-term impacts. In order to maintain ecosystem services in response to long-term impacts, restoration efforts may require novel approaches, such as the introduction of non-native species, facilitated movement of native species to new habitats (e.g., white pine), and aggressive management of existing species (e.g., Rhododendron) with mechanical removal, fire, or chemicals.

Old-growth stands showed a wide range of tree ages (>300years) and low tree densities for several centuries; rapid early growth produced trees with large crowns and diameters, as well as low height-to-diameter ratios. In contrast, young stands established much quicker and at higher tree densities; beyond their initial 20years, trees had smaller diameters at equivalent ages, slower growth rates, smaller crowns and higher H:D than trees in old-growth stands. Low-intensity disturbance, likely dominated by fire, was common in old-growth stands during their early development. Fire scars showed these stands burned frequently from 1700 to 1900, and low levels of tree recruitment occurred in a complex relationship with fire during this 200years. There was no evidence of fire, however, in either old-growth or young stands after 1909, and their densities were well above that of 1900; in old-growth stands, 15-25% of the basal growth occurred from 1950 to 1990, and it appears that they are on a development pathway different from what they experienced from 1700 to 1900. Furthermore, tree recruitment has been limited in both old-growth and young stands since 1950 while biomass and fuels continue to accumulate rapidly. Past stand dynamics can be emulated by prescribed fire and light thinning to reduce risk of loss from severe fire or insects, as well as to partially restore stand conditions that existed prior to fire exclusion. Our results suggest that young stands can be grown to produce high levels of biomass/wood, or their development can be altered to more closely follow that of old-growth stands depending on management objectives.

In vitro tests showed that mustard EO and AIT had the greatest inhibition of Salmonella, followed by cinnamon EO and cinnamaldehyde, while oregano and carvacrol showed the least inhibition. Scanning electron microscopy images of S. Typhimurium on tomatoes suggest that the EOs and their major components damaged the bacteria, and the damage was more obvious after posttreatment storage at 10 degree C for 4 and 7 d. Salmonella on inoculated tomatoes was reduced by more than 5 log colony forming units (CFU)/g by mustard EO and AIT, by 4.56 and 3.79 log CFU/g following cinnamon EO and cinnamaldehyde treatments, respectively, and 1.54 and 3.37 log CFU/g after oregano EO and carvacrol treatments, respectively. Mustard EO and AIT induced discoloration, softening, and loss of the vitamin C and lycopene during 21 d of storage at 10 degree C, while treatment with cinnamon EO and cinnamaldehyde did not result in significant changes in tomato quality. Tomatoes treated with oregano EO had better quality than nontreated samples after storage. Therefore, treatment with cinnamon and oregano EO and their major components appeared to be feasible for inactivation of Salmonella on tomatoes and maintaining quality.

When farmed, this water is often drained via a tile riser, a vertical tube that connects the bottom of the low point of a closed depression with the subsurface tile drainage network. Two field-sized closed depressions (ca. 4ha) and two small catchments (ca. 300ha) were used to test the hypothesis that water quality could be improved by replacing tile risers with blind inlets, ca. 18m2 holes filled to 1m depth so that a high infiltration capacity was attained. At the field scale discharge, sediment and nutrient loads were lower when drained with the blind inlet compared to the tile riser. Late Spring 2010 was much wetter than normal, and increased nutrient loading was observed in both small catchments compared with previous years. In 2010, discharge and total P loading from Catchment AME (control catchment drained with tile risers) increased 417% and 737%, respectively, compared to the mean for the six previous years, whereas in Catchment BME (treatment catchment drained with blind inlets), there was only a 64% and 92% increase, respectively. Results from this study indicate that replacing tile risers with blind inlets to drain closed depressions may be one method to effectively reduce nutrient and sediment loading to Lake Erie and other sensitive water bodies that lie in landscapes formed by Wisconsin, Weichselian or Devensian glaciation.

In western North America, mass-balance records span four to five decades and capture a relatively narrow window of glacial behavior over an interval that was dominated by warming and ablation. We use temperature- and moisture-sensitive tree-ring series to reconstruct annual mass balance for six glaciers in the Pacific Northwest and Alaska. Mass-balance models rely on the climatic sensitivity of tree-ring chronologies and teleconnection patterns in the North Pacific. The reconstructions extend through the mid to latter portions of the Little Ice Age (LIA) and explore the role of climate variability in forcing mass balance across multiple environmental gradients. Synchronous positive mass-balance intervals coincide with regional moraine building and solar minima, whereas differences in LIA glacier behavior are related to synoptic climate forcing. Secular warming in the late 19th century to present corresponds with the only multi-decadal intervals of negative mass balance in all glacier reconstructions. This suggests that contemporary retreat in western North America is unique with respect to the last several centuries and that regional patterns of glacier variability are now dominated by global climate forcing.

A secondary fermentation can occur after sugars are consumed that results in the formation of acetic, propionic, and butyric acids, concomitantly with the loss of lactic acid and an increase in pH. Spoilage fermentations can result in significant economic loss for industrial producers. The microbiota that result in spoilage remain incompletely defined. Previous studies have implicated yeasts, lactic acid bacteria, enterobacteriaceae, and Clostridia as having a role in spoilage fermentations. We report that Propionibacterium and Pectinatus isolates from cucumber fermentation spoilage converted lactic acid to propionic acid, increasing pH. The analysis of 16S rDNA cloning libraries confirmed and expanded the knowledge gained from previous studies using classical microbiological methods. Our data show that Gram-negative anaerobic bacteria supersede Gram-positive Fermincutes species after the pH rises from around 3.2 to pH 5, and propionic and butyric acids are produced. Characterization of the spoilage microbiota is an important first step in efforts to prevent cucumber fermentation spoilage. Practical ApplicationAn understanding of the microorganisms that cause commercial cucumber fermentation spoilage may aid in developing methods to prevent the spoilage from occurring.

These samples with smooth and homogenous surfaces were examined for their property, biodegradability and water absorption. Scanning electron microscopy revealed that the fibers were well dispersed in the matrix. In addition, it was found that the fibers and matrices interacted strongly. Blends with 20 % (dry weight-basis) fiber content showed some fiber agglomeration. Whereas blends with 10 % fibers showed increased crystallinity and lower water absorption capacity. The CO sub(2) evolution study showed that the thermoplastic starch samples without any additives had the highest rate and extent of degradation whereas the neat PCL samples had the lowest degradation rate. Addition of fiber to the TPS/PCL blend exhibited the degradation rates and extents that were somewhere in between the pure TPS and neat PCL. This work demonstrates that TPS/PCL composites reinforced with bleached sisal has superior structural characteristics and water resistance and thus, can be used as polymeric engineering composites for different applications.

NRRL Y-50464 that is capable of utilizing cellobiose as sole source of carbon and energy by producing sufficient native beta -glucosidase enzyme activity without further enzyme supplementation for cellulosic ethanol production using simultaneous saccharification and fermentation. Eliminating the addition of external beta -glucosidase reduces the cost of cellulosic ethanol production. In this study, we present results on the isolation and identification of a beta -glucosidase protein from strain Y-50464. Using Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and blast search of the NCBInr database (National Center for Biotechnology Information nonredundant), the protein from Y-50464 was identified as a beta -glucosidase (BGL1) with a molecular weight of 93.3 kDa. The BGL1 protein was purified through multiple chromatographic steps to a 26-fold purity (K sub(m)=0.355 mM [pNPG]; K sub(i)=15.2 mM [glucose]), which has a specific activity of 18.4 U/mg of protein with an optimal performance temperature at 45 degree C and pH of 6.0. This protein appears to be intracellular although other forms of the enzyme may exist. The fast growth rate of Y-50464 and its capability to produce sufficient beta -glucosidase activity for ethanol conversion from cellobiose provide a promising means for low-cost cellulosic ethanol production through a consolidated bioprocessing development.

Dicerandra immaculata Lakela var. immaculata (Lamiaceae) is a critically endangered plant known only from a few locations in scrub habitat in Florida. Using seven sites where populations of D. immaculata were wild, introduced, and/or extirpated, we sought to answer the following questions: (1) how do habitat characteristics at locations supporting wild D. immaculata plants vary from random locations within the same habitat; (2) how do habitat characteristics differ between wild and extirpated populations; and (3) how do habitat characteristics differ between wild and introduced populations? At locations of wild D. immaculata, community structure had fewer woody stems, shorter understory vegetation, lower percent canopy coverage, and lower percent ground cover of detritus than random locations and locations with extirpated D. immaculata. In addition, bare ground decreased at extirpated locations because other plant species expanded their coverage, water saturation of the soil increased, diversity of shrubs decreased, and composition of the overstory changed compared to that of wild locations. Habitat characteristics associated with introduced plants were more similar to characteristics at randomly chosen locations than those with wild plants. However, introduced plants tended to occupy locations that had drier soil, a higher abundance of conspecifics, and a higher proportion of woody understory plants than that of random locations. Overall, gaps in the canopy and at ground level are likely essential for survival and recruitment of D. immaculata.

New policy and program approaches are needed to restore and sustain natural systems as public agencies and organizations face greater demands and declining budgets. Environmental stewardship is an often overlooked intervention strategy, and the full potential of civic engagement by citizens on behalf of ecosystem health is little understood. Using a coupled systems approach, integrated analysis of social and ecological footprints can lead to greater theoretical understanding and more effective programs at the landscape scale. Here we outline two pilot studies as part of an emergent research program that is investigating the extent and impact of environmental stewardship. Qualitative interviews of stewardship managers revealed multiple dimensions of motivations and purposes for stewardship, ranging from the practical to the conceptual. A regional organization census yielded a surprisingly large number of organizations that conduct stewardship, with social and ecological values being of comparable emphasis. The initial research is based in the Puget Sound area of Washington State, U.S., but results have relevance to other urban areas. Pilot study findings now guide additional research effort about motivations, organizational networks, and theory of integrated socio-ecological systems to be derived from comprehensive footprint analysis of stewardship activity.

The SWP-32 antibody was used for the development of an enzyme-linked immunosorbent assay (ELISA). We also compared the efficiency of this ELISA to microscopy and quantitative real-time (qRT) PCR, the methods currently in use. ELISA is comparable in sensitivity with the qRT-PCR, less expensive and faster. When this method is commercialized and made available to bee-keepers, it will allow them to make informed decisions for the application of in-hive chemicals. Hence, bee-keepers may be able to determine when treatments for control of N. ceranae are unnecessary and reduce the cost, time and possible side effects of these treatments. This assay provides the first serological method for detection of N. ceranae in bee colonies, which is as sensitive as DNA amplification. It can be easily adopted for both laboratory and field applications. JF - Journal of Applied Microbiology AU - Aronstein, KA AU - Webster, T C AU - Saldivar, E AD - Honey Bee Research Unit.

We used a long-term (13-year) pulse-perturbation experiment featuring heavy grazing and shrub removal to determine if critical thresholds and their determinants can be demonstrated in Chihuahuan Desert grasslands. We asked if cover values or patch-size metrics could predict vegetation recovery, supporting their use as early-warning indicators. We found that season of grazing, but not the presence of competing shrubs, mediated the severity of grazing impacts on dominant grasses. Recovery occurred at the same rate irrespective of grazing history, suggesting that critical thresholds were not crossed, even at low cover levels. Grass cover, but not patch size metrics, predicted variation in recovery rates. Some transition-prone ecosystems are surprisingly resilient; management of grazing impacts and simple cover measurements can be used to avert undesired transitions and initiate restoration.

Fifteen Gram-negative bacterial isolates were recovered from the skin lesions of diseased yellow perch (Perca flavescens). Based on API 20NE test, ten isolates were found to share 67.2-99.9% homologies with Chryseobactertium indologenes. Based on fatty acid methyl ester analysis, 13 isolates were found to share similarities with C. indologenes and other species of Chryseobacterium. Based on sequencing results of partial 16S rRNA gene, 13 isolates shared 99% identities (e value = 2e-50) with the 16S rRNA sequence of C. indologenes (GenBank HQ259684). Based on the 16S-23S rRNA intergenic spacer region (ISR) sequence, the 13 isolates shared 88% identity (e value = 1e-165) with the 16S-23S ISR sequence of C. indologenes (GenBank EU014570). T-coffee multiple sequence alignment revealed that the partial 16S rRNA or the 16S-23S ISR sequence of the 13 isolates shared 100% identity with each other. When healthy yellow perch were exposed to the 15 isolates by bath immersion (c. 6 107 CFU ml-1 for 1 h), only C. indologenes isolates killed 10-20% of fish, whereas other isolates were avirulent. When yellow perch were exposed to C. indologenes by intraperitoneal injection, mortality was dose dependent, with LD50 and LD95 values of 1.5 108 and 3.2 108 CFU per fish, respectively. This is the first report on the isolation of C. indologenes from diseased yellow perch. Virulence studies suggested that C. indologenes could become pathogenic to yellow perch.Original Abstract: Chryseobactertium indologenes could be pathogenic to yellow perch.

However, understanding the true diversity and ecology of these organisms is hampered by convergent morphologies between species. The application of molecular techniques has enabled greater resolution of species than allowed by morphology alone. In particular, the commonly used biocontrol agent M. anisopliae was found to be a species complex composed of nine species. This prior work was conducted with commonly used markers in fungal phylogenetics (BTUB, RPB1, RPB2 and TEF), which likely under-represent diversity in the M. anisopliae complex. Using sequence data from nuclear genomes of M. acridum and M. robertsii we identified regions of conserved gene synteny and developed primers to amplify intergenic regions of seven loci. Using ex-type and authenticated tissue specimens for species in the M. anisopliae complex, we demonstrate that sequence data derived from intergenic loci is more variable and phylogenetically informative than previously available markers. These new markers will facilitate investigations at or below the species level for the M. anisopliae complex. The method of marker development employed here should be extendable to any group with sufficiently divergent genome data available.

The abundance profile of assigned functions within the Lactobacillus plantarum genome was used for the identification of the putative and unique gene sequence, csh. The targeted gene (csh) was used as the template for PCR amplification and construction of a non-radioactive DIG labeled probe. The csh derived probe aided in the preliminary and rapid identification of L. plantarum from mixed cultures by colony hybridization. The method described here for the rapid identification of L. plantarum can also be applied for the rapid detection of other bacteria if a unique gene sequence can be identified from its complete genome sequence.

M. Greef & Deuter ex Hodk. & Renvoize) to the southern Great Plains is key to maximizing productivity by matching each grass variety to its optimal production environment. The objectives of this study were: (1) to quantify latitudinal variation in production of representative upland switchgrass ecotypes (Blackwell, Cave-in-Rock, and Shawnee), lowland switchgrass ecotypes (Alamo, Kanlow), and Miscanthus in the southern half of the US Great Plains and (2) to investigate the environmental factors affecting yield variation. Leaf area and yield were measured on plots at 10 locations in Missouri, Arkansas, Oklahoma, and Texas. More cold winter days led to decreased subsequent Alamo switchgrass yields and increased subsequent upland switchgrass yields. More hot-growing season days led to decreased Kanlow and Miscanthus yields. Increased drought intensity also contributed to decreased Miscanthus yields. Alamo switchgrass had the greatest radiation use efficiency (RUE) with a mean of 4.3 g per megajoule intercepted PAR and water use efficiency (WUE) with a mean of 4.5 mg of dry weight per gram of water transpired. The representative RUE values for other varieties ranged from 67 to 80 % of Alamo's RUE value and 67 to 87 % of Alamo's WUE. These results will provide valuable inputs to process-based models to realistically simulate these important perennial grasses in this region and to assess the environmental impacts of production on water use and nutrient demands. In addition, it will also be useful for landowners and companies choosing the most productive perennial grasses for biofuel production.

The individual influence of nutrients and atrazine on periphyton has been extensively studied, but their impact when introduced together and with multiple agricultural pollutants is less clear. We simulated a field-scale runoff pulse into a riverine wetland that mimicked pollutant composition typical of field runoff of the Mississippi River Alluvial Plain. Periphyton biomass and functional responses were measured for 2 weeks along a 500 m section. Additionally, laboratory chamber assays were used to identify potential periphyton changes due to nutrients, atrazine, and their interactions. Generally, nutrients stimulated, and atrazine reduced chlorophyll a (Chl a) in chambers. In the wetland, nutrient and atrazine relationships with periphyton were weaker, and when found, were often opposite of trends in chambers. Total nitrogen (TN) was inversely related to Chl a, and total phosphorus was inversely related to respiration (R) rates. Atrazine (10-20 mu g L super(-1) in the wetland) had a positive relationship with ash-free dry mass (AFDM), and weakened the relationship between TN and AFDM. Wetland periphyton biomass was better correlated to total suspended solids than nutrients or atrazine. Periphyton function was resilient as periphyton gross primary production (GPP)/R ratios were not strongly impacted by runoff. However, whole-system GPP and R decreased over the 2-week period, suggesting that although periphyton metabolism recovered quickly, whole-system metabolism took longer to recover. The individual and combined impacts of nutrients and atrazine in complex pollutant mixtures can vary substantially from their influence when introduced separately, and non-linear impacts can occur with distance downstream of the pollutant introduction point.

Three cultivars (Dale, Theis, and M81-E) were harvested at 90, 115, and 140 days after planting. Stalks were stripped of leaves and topped at the peduncle, then divided into four treatments (whole stalk, 20- or 40-cm billets, or chopped). The sorghum was stored outside at ambient temperature in a shade tent, and juice was extracted from samples removed at 0, 1, 2, and 4 days after harvest. Changes in juice Brix and sugars were reported in an earlier paper (Lingle, Tew, Rukavina, Boykin, Post-harvest changes in sweet sorghum I: Brix and sugars, BioEnergy Research 5:158-167, 2012). In this paper, we report changes in juice pH, titratable acidity (TA), and protein, starch, and mannitol concentrations. Juice pH dropped rapidly after harvest in chopped sorghum, but changed little during 4 days of storage in whole stalks or billets. Similarly, TA increased with storage time in chopped samples, but was unchanged in whole stalks and billets. Protein concentration was highly variable, and no pattern with treatment or storage time could be discerned. In whole stalks and billets, starch content slowly decreased during storage, while in chopped samples starch appeared to increase. This was most likely a result of an increase in dextran synthesized by microorganisms in those samples, which was also detected by the enzymatic starch assay. The concentration of mannitol increased with storage time in chopped samples, but not in whole stalks or billets. Within a harvest date, pH was highly correlated with total sugar, while TA and mannitol were highly negatively correlated with total sugar. The results confirm that whole stalks and billets were little changed over 4 days of storage, while chopped sorghum was badly deteriorated 1 day after harvest. Changes in pH, TA, or mannitol could be used to measure deterioration in sweet sorghum after harvest.

Moench] as a bioenergy crop is an adequate seed supply, which will require development of hybrid varieties using dwarf seed-parent lines. A set of six public sweet sorghum A-lines (Dwarf Kansas Sourless, KS9, N36, N38, N39, and N4692) were crossed with a set of six public sweet sorghum cultivars (Brawley, Kansas Collier, Dale, Sugar Drip, Waconia, and Wray). Grain, fiber, and sugar yields were determined, and conversion formulas were applied to estimate ethanol yields. Hybrids were grown in fields at Ithaca, NE, USA, in 1983-1984 fertilized with 112 kg ha super(-1) N. In terms of yield components and overall ethanol yields, one A-line, N38, was inferior. Average total ethanol yields from hybrids made on the other A-lines were not significantly different, suggesting that any of those five A-lines could be useful seed-parents. With the exception of grain yield, cultivars used as pollen parents were among the highest-performing entries for all traits. For all traits directly contributing to total ethanol yield (grain yield, juice yield, % soluble solids, sugar yield, fiber yield), hybrids were also among the highest-performing entries. Results of this study demonstrate that hybrid sweet sorghum with performance criteria equivalent to existing sweet sorghum cultivars can be produced on the sweet sorghum seed-parent lines A-Dwarf Kansas Sourless, A-KS9, A-N36, A-N39, and A-N4692. Identification of specific seed-parent pollen parent lines with characteristics best suited for particular growing regions and end-user needs will be critical for commercial hybrid development.

They have to advise consumers, but relying on ambiguous and evolving information raises the question, how do consumers respond to changing advice? Here, we estimate a model of the retail demand for tomatoes in the USA, accounting for the 2008 events in the USA in which consumers were advised that some types of tomatoes were contaminated with Italic Salmonella bacteria, and later were advised that tomatoes were safe and peppers were not. Using the quantity of news media attention given to the Salmonella issue, we show that consumers generally responded to the advice that tomatoes were contaminated, but did not respond to the declaration that tomatoes were safe. The magnitude of response to contemporaneous news depended on the extent of coverage in previous weeks.

Genome sequencing of S. thermophilus has identified a genetic locus encoding a quorum sensing (QS) system that regulates production of class II bacteriocins. However, in strains possessing this gene cluster, production of bacteriocin like peptides (Blp) was only observed when excess pheromone was provided. PCR analysis revealed this strain possessed blpC, which encodes the 30-mer QS pheromone. To investigate if BlpC regulates bacteriocin production in S. thermophilus B59671, an integrative vector was used to replace blpC with a gene encoding for kanamycin resistance and the resulting mutant did not inhibit the growth of Pediococcus acidilactici. Constitutive expression of blpC from a shuttle vector restored the bacteriocin production, confirming the blp gene cluster is essential for bacteriocin activity in S. thermophilus B59671.

Physiological resistance and disease avoidance conferred by plant architecture-related traits contribute to white mold field resistance. Our objective was to further examine white mold disease avoidance in common bean. A comparative map composed of 79 quantitative trait loci (QTL) for white mold resistance (27), disease avoidance traits (36) and root traits (16) was generated. Thirteen white mold resistance QTL, six with strong and seven with weak associations with disease avoidance traits, were observed. Root length and lodging QTL co-located in three regions. Canopy porosity and height, and lodging were highly correlated with disease severity score in field screening trials conducted from 2000 to 2011. Resistance to lodging was extremely important for reducing disease severity in both dry and snap bean (r=0.61 across 11 trials). Avoidance traits were less effective in reducing disease severity in trials with heavy disease pressure. Dry bean lines with physiological resistance in combination with disease avoidance traits did not require fungicide application to protect yield potential under moderate and heavy disease pressure. Given the complexity of disease resistance as evidenced by the comparative QTL map, marker-assisted breeding for disease avoidance is not recommended at this time. Instead, selecting for resistance to white mold in the field, in combination with high yield potential and acceptable maturity, is the recommended strategy for improving both disease avoidance and physiological resistance to white mold in cultivars with commercially acceptable agronomic traits.

AN - 1288995861; 23233324 AB - Chlorothalonil concentrations exceeding acute toxicity levels for certain organisms have been measured in surface water discharge events from managed turf watersheds. The duration of exceedence and the timing of these events related to precipitation/runoff and time since application, however, have not been explored. Chlorothalonil concentrations were measured from discharge waters draining a managed turf watershed in Duluth, Minnesota, USA, between 2003 and 2009. The median chlorothalonil concentration was 0.58 µg/L. Approximately 2% of all measured concentrations exceeded the 7.6 µg/L median lethal concentration (LC50) acute toxicity level for rainbow trout. One-twentieth the LC50 concentration, equivalent to the level of concern (0.38 µg/L) for endangered species, was exceeded 31% of the time during the present study. The concentrations that exceeded the LC50 threshold were associated with eight rainfall/runoff events. Low dose exposures are a more important biological concern than acute occurrences. Exceedence concentrations associated with acute effects were significantly (p < 0.05) correlated to time since application and were measured only in the fall following extensive application. A conflict exists between the transportability of chlorothalonil as suggested by its chemical properties and the data collected in the present study. With respect to course-wide golf course application, avoiding application until after the major autumn rainfall period but before the first snow coverage is recommended to reduce occurrence of chlorothalonil concentrations that exceed toxic levels associated with acute and chronic levels of concern.

We use a geopedological classification to organize the landscape into five categories from broad scale to fine scale: (1) physiographic divisions which describe regional topography, such as mountains and basin floors; (2) regolith type which identifies residuum versus transported sediments; (3) parent materials which describe mineralogy; (4) landforms which provide meso-scale descriptions of topography; and (5) soil texture, a fine-scale variable important for infiltration, erodibility, and available water holding capacity. The study was conducted in a 1753 km2 area of the White Sands Missile Range and easternmost Jornada Experimental Range and revealed the following. (1) At the broadest scale, mesquite is dominant on the basin floor when the parent material is siliceous sand, but (2) biological soil crust becomes dominant in the basin floor when the parent material is gypseous. (3) Creosotebush is dominant on rocky soils of the piedmont slopes regardless of parent material, but (4) grasslands become dominant on the bajadas upslope in the semiarid zone and into the semiarid mountain uplands regardless of bedrock type. This method provides a way of supplementing ecologic-edaphic studies and provides a framework within which mechanisms can be explored.

This work examined atrazine fate and transport in a field adjacent to Puerto Rico's Jobos Bay National Estuarine Research Reserve. The herbicide's use was linked to residue detection in shallow groundwater and movement toward the estuary; however, data indicated that transport via this pathway was small. In contrast, surface runoff as tropical storm systems moved through the area appeared to have high potential for atrazine transport. In this case, transport to the estuary was limited by runoff event timing relative to atrazine application and very rapid atrazine dissipation (DT50=1-3days) in field soil. Soil incubation studies showed that accelerated degradation conditions had developed in the field due to repeated atrazine treatment. To improve weed management, atrazine replacement with other herbicide(s) is recommended. Use of products that have greater soil persistence may increase runoff risk.

Here we describe a 7-plex microbead-based immunoassay to simultaneously serotype seven STECs (i.e., belonging to serogroups O26, O45, O103, O111, O121, O145, and O157) by the Luminex xMAP registered technology. This technology presents many advantages: Its multiplexed format (up to 100 analytes) saves time, reagents, and test sample, and many regulatory agencies currently utilize this platform for other assays. In this study, a total of seventy-nine STEC strains belonging to the 7 different serogroups of interest were tested. These strains had been previously serotyped and their serogroup was confirmed by PCR. Except for one strain belonging to the O111 serogroup, nearly all strains (i.e., 98.7%; 78/79) were correctly identified on the Bio-Plex 100 instrument in less than 4h. This newly developed microbead-based immunoassay could be extended to include other STEC serogroups, virulence factors, and/or bacterial species.

The assay uses primers WG-OLS-F1 and WG-OLS-R1 and the fluorescent probe WG-OLS-P1, designed based on unique sequences found only in the genome of oleander strain Ann1. The assay is specific, allowing detection of only oleander-infecting strains, not other strains of X. fastidiosa nor other plant-associated bacteria tested. The assay is also sensitive, with a detection limit of 10.4fg DNA of X. fastidiosa per reaction in vitro and in planta. The assay can also be applied to detect low numbers of X. fastidiosa in insect samples, or further developed into a multiplex real-time PCR assay to simultaneously detect and distinguish diverse strains of X. fastidiosa that may occupy the same hosts or insect vectors. Specific and sensitive detection and quantification of oleander strains of X. fastidiosa should be useful for disease diagnosis, epidemiological studies, management of oleander leaf scorch disease, and resistance screening for oleander shrubs.

The objective of this study was to expose naive channel catfish (Ictalurus punctatus) to naturally infected fish that carried Ich and E. ictaluri to provide clinical evidence for transmission of both pathogens. Three tanks of fish were exposed to naturally coinfected fish and two tanks were utilized as mock-infected controls in each of two trials. In trial I, 34 out of 60 fish (56.7%) exposed to two infected fish per tank died at day one. All remaining fish died two days post exposure. Of the dead fish, all showed heavy Ich infection and E. ictaluri was isolated from the kidney of 60% of the dead catfish. In trial II, the cumulative mortality in fish exposed to 2 coinfected fish per tank was less than 20% during days 1-7 post exposure. Most of the fish died from 8 to 14days post exposure to the coinfected fish. Ninety-six percent of fish were positive for both Ich and E. ictaluri in trial II. The results demonstrated that fish naturally coinfected with Ich and E. ictaluri could concomitantly transmit both pathogens to naive fish. In aquaculture management, precaution is needed to thoroughly examine fish prior to shipment or purchase to prevent the spread of aquatic animal pathogens.

AN - 1287886140; 23331165 AB - The Gram-negative bacterium Flavobacterium columnare is the cause of columnaris disease, which can occur in channel catfish ( Ictalurus punctatus ). In a previous study, the betaine-type alkaloid ungeremine, 1, obtained from Pancratium maritimum L. was found to have strong antibacterial activity against F. columnare. In this study, analogues of 1 were evaluated using a rapid bioassay for activity against F. columnare to determine if the analogues might provide greater antibacterial activity and to determine structure-activity relationships of the test compounds. Several ungeremine analogues were prepared by hydrochlorination of the alkaloid and by selenium dioxide oxidation of both lycorine, 7, and pseudolycorine, 8, which yielded the isomer of ungeremine, 3, and zefbetaine, 4, respectively. The treatment of lycorine with phosphorus oxychloride allowed the synthesis of an anhydrolycorine lactam, 5, showing, with respect to 1, the deoxygenation and oxygenation of C-2 and C-7 of the C and B rings, respectively. The results of the structure-activity relationship studies showed that the aromatization of the C ring and the oxidation to an azomethine group of C-7 of the B ring are structural features important for antibacterial activity. In addition, the position of the oxygenation of the C ring as well as the presence of the 1,3-dioxole ring joined to the A ring of the pyrrolo[de]phenanthridine skeleton also plays a significant role in imparting antibacterial activity. On the basis of 24-h 50% inhibition concentration (IC(50)) results, ungeremine hydrochloride, 2, was similar in toxicity to 1, whereas 5 had the lowest activity. Analogue 2 is soluble in water, which may provide the benefit for use as an effective feed additive or therapeutant compared to ungeremine.

It is closely related to the etiologic agent of turkey coryza, Bordetella avium. Distinguishing between B. avium and B. hinzii is difficult, and there is no method for identification of B. hinzii suitable for use by diagnostic laboratories. This report details the development of a B. hinzii-specific PCR targeting the ompA gene. Assay sensitivity is 100% based on analysis of 48 B. hinzii isolates from diverse geographic locations representing all known ribotypes. Evaluation of 71 isolates of B. avium and 20 other bacterial isolates from poultry, comprising gram-negative and gram-positive commensals and pathogens of nine genera, demonstrated an assay specificity of 100%. The ompA PCR is a rapid, reliable, and accurate method for identification of B. hinzii and provides a valuable new tool for veterinary diagnostic laboratories investigating poultry respiratory disease outbreaks.

Mitigation of thermal stress can improve productivity, but it must be achieved economically. The objective of this study was to evaluate the effects of varied levels of air velocity on the productivity of laying hens housed under evaporatively cooled conditions by assessing hen-day egg production (HDEP), fred consumption (FC), feed consumption per dozen eggs (FD) feed conversion ratio (FCR), and egg weight (EW). FC was observed to increase with air velocity PD increased with increasing air velocity and was significantly greater for both air velocity treatments compared to still air other measures of performance including LW and PCR were not different, suggesting that the improvement in HDEP resulted from increased FC. Increased convective cooling increases productivity of laying hens during hot weather by improving thermal comfort when evaporative cooling is limited by weather or system design.

A new drift reduction technology incorporating laser scanning capabilities with a variable-rate air-assisted sprayer was developed to address these problems. This new sprayer, the same sprayer with the variable-rate function disabled, and a conventional constant-rate air-blast sprayer were tested for comparison of spray drift and off-target losses in an apple orchard. Tests were conducted at three different growth stages: trees just beginning to leaf (leafing), halffoliage, and full foliage. Spray deposits from spray drift and offtarget losses were collected within tree rows at ground level, above and behind the sprayed trees, in the spaces between trees, and from 3.2 m tall poles at 5, 15, and 35 m from the tree rows. Compared to the constant-rate sprayers, the laserguided variable-rate sprayer reduced average spray losses on the ground by 68% to 90% and around tree canopies by 70% to 92%, reduced airborne spray drift by 70% to 100%, and most importantly, reduced the spray volume by 47% to 73%, while spray deposition quality inside the canopy for these sprayers was comparable. These results demonstrate that the variable-rate sprayer incorporating the innovative laser scanning technology reduced spray drift and off-target losses of pesticides, was environmentally sustainable, and was economically beneficial to growers.

To address this problem, a variable-rate air-assisted sprayer implementing laser scanning technology was developed to apply appropriate amounts of pesticides based on tree canopy characteristics including tree height, width, volume, foliage density, and occurrence. The new sprayer performance was evaluated in an apple orchard by quantifying spray deposition inside canopies at three different growth stages (leafing, half-foliage, and full-foliage) with three sprayer treatments: the new variable-rate sprayer (S sub(1)), the same sprayer without the variable-rate function (S sub(2)), and a conventional air-blast sprayer (S sub(3)). Their spray coverage and deposits inside canopies were measured and compared with water-sensitive papers and nylon screens. The three sprayer treatments provided fairly consistent spray coverage and deposits in the spray direction (or canopy depth direction) at the leafing stage. The variations in spray coverage and deposits in the spray direction increased considerably for S sub(2) and S sub(3) at the halffoliage and full-foliage stages. S sub(1) produced better uniformity in spray coverage and deposits across the tree height direction than S sub(2) and S sub(3) at all growth stages. Compared to constant-rate sprayers, the new variable-rate sprayer only consumed 27% to 53% of the spray mixture while still achieving adequate spray coverage inside the canopies. In addition, the spray deposition from the new sprayer was very consistent regardless of the canopy growth stage. Therefore, the new sprayer increased spray efficiency and improved spray accuracy by greatly lowering the possibility of overspray, resulting in reduced spray costs and potential reduction of environmental pollution.

These pathogens have the ability to attack the roots, seedlings, and flowering heads of barley and wheat plants with disease, resulting in yield loss and head blight disease and also resulting in the contamination of grain with mycotoxins harmful to human and animal health. There is increasing evidence that brassinosteroid (BR) hormones play an important role in plant defense against both biotic and abiotic stress agents and this study set out to determine if and how BR might affect Fusarium diseases of barley. Application of the epibrassinolide (epiBL) to heads of 'Lux' barley reduced the severity of Fusarium head blight (FHB) caused by Fusarium culmorum by 86% and reduced the FHB-associated loss in grain weight by 33%. Growth of plants in soil amended with epiBL resulted in a 28 and 35% reduction in Fusarium seedling blight (FSB) symptoms on the Lux and 'Akashinriki' barley, respectively. Microarray analysis was used to determine whether growth in epiBL-amended soil changed the transcriptional profile in stem base tissue during the early stages of FSB development. At 24 and 48 h post F. culmorum inoculation, there were 146 epiBL-responsive transcripts, the majority being from the 48-h time point (n = 118). Real-time reverse-transcription polymerase chain reaction analysis validated the results for eight transcripts, including five defense genes. The results of gene expression studies show that chromatin remodeling, hormonal signaling, photosynthesis, and pathogenesis-related genes are activated in plants as a result of growth in epiBL.

Vitis vinifera, show varying levels of susceptibility to Eutypa dieback and Esca, in terms of foliar symptoms. However, little is known regarding cultivar susceptibility of their woody tissues to canker formation. Accordingly, we evaluated the relative susceptibility of V. vinifera cultivars ('Cabernet Franc', 'Cabernet Sauvignon', 'Chardonnay', 'Merlot', 'Riesling', 'Petite Syrah', and 'Thompson Seedless') and species or interspecific hybrids of North American Vitis (Vitis hybrid 'Concord', V. arizonica 'b42-26', V. rupestris x V. cinerea 'I11547-1', and Fennell 6 [V. aestivalis] x Malaga [V. vinifera] 'DVIT0166') to canker formation by seven trunk pathogens (Neofusicoccum parvum, Lasiodiplodia theobromae, Phaeomoniella chlamydospora, Togninia minima, Phomopsis viticola, Eutypa lata, and an undescribed Eutypa sp.). Susceptibility was based on the length of wood discoloration (LWD) in the woody stems of rooted plants in duplicate greenhouse experiments. Cultivars of V. vinifera and Concord did not vary significantly in susceptibility to N. parvum or L. theobromae (LWD of 21 to 88 mm at 14 weeks post inoculation; P > 0.16), suggesting that they are similarly susceptible to Botryosphaeria dieback. The table-grape Thompson Seedless was most susceptible to P. viticola (mean LWD of 61 mm at 11 months post inoculation; P < 0.0001). V. vinifera cultivars and Concord showed similar susceptibility to the Esca pathogens. Phaeomoniella chlamydospora and T. minima. Susceptibility to E. lata was greatest in V. arizonica b42-26 (mean LWD of 96 mm at 11 months post inoculation; P < 0.03). In fact, all four American Vitis spp. were more susceptible to Eutypa dieback than the V. vinifera cultivars. Our findings suggest that no one cultivar is likely to provide resistance to the range of trunk pathogens but that certain cultivars may be promising candidates for commercially relevant host resistance in grape-production systems where the dominant cultivars are very susceptible.

Diseased plants in nature exhibited angular-shaped leaf spotting symptoms on leaf margins and central leaf areas. The isolates were cultured from diseased leaf tissue and tentatively identified as Xanthomonas spp., and their virulence on common cocklebur seedlings compared. The most virulent isolate (LVA987) was used in studies to define disease progression on cocklebur seedlings and to carry out a host range evaluation on various weeds and crop plants. High virulence was found on common cocklebur > marestail (Conyza canadensis) > giant ragweed (Ambrosia trifida) greater than or equal to and common ragweed (Ambrosia artemisifolia). These results suggest this pathogen may be useful for the biological control of these important species of weeds. This is also highly relevant since all of these weeds have evolved resistance to one or more synthetic herbicides and are thus becoming more difficult to control with conventional herbicides.

In that study, the biopesticide, a formulation of a fungal pathogen of arthropods, Beauveria bassiana, failed to have any negative impact on the mite infestation despite successful results in previous studies using uncontaminated batches of the same biopesticide. The objective of the present research was to determine whether the bacteria may have interfered with the infectivity and/or virulence of B. bassiana in a simplified system; positive results in that system would then provide a rationale for further work under more complex conditions. Galleria mellonella late instar larvae treated topically with both a bacterial suspension of 6.8 to 7.0 x 10 super(7) cfu/ml and a fungal suspension of 2.5 x 10 super(7) or 2.5 x 10 super(8) B. bassiana conidia/ml showed, in the case of one of the bacterial strains, significantly increased survivorship compared to larvae treated with just the B. bassiana suspension. When larvae were immersed in a bacterial suspension prior to application of B. bassiana suspension using a spray tower, a significant positive effect of the same P. fluorescens strain on larval survivorship was observed at 2.5 x 10 super(8) conidia/ml. Neither the bacterial suspensions alone nor blank control solutions had any effect on larval survivorship. These results show that an interaction between the bacteria and the pathogen may explain some of the results from the prior field trial.

Little research has described temporal and spatial patterns of human-coyote conflicts, although such information can be an important step in developing and optimizing management efforts. We used reports from 22 entities within the Denver Metropolitan Area (DMA) in Colorado that provided information on coyote observations (signs, sightings, and encounters) and conflicts (incidents, pet-attacks, and human-attacks). Our objectives were to 1) define, quantify, and map categories of coyote observations and conflicts, and 2) investigate temporal and spatial patterns of conflicts, particularly related to land cover types and housing density classes. We compiled 4,006 coyote reports, including 78 signs (1.9%), 3,023 sightings (75.5%), 395 encounters (9.9%), 26 incidents (0.6%), 471 pet-attacks (11.8%), and 13 human-attacks (0.3%). We found a strong seasonal pattern with reports of both observations and conflicts highest during December-March and lowest during July-September. Numbers of coyote conflicts were disproportionately greater in open space and development land cover types (in contrast to natural and agricultural land cover) and in suburban housing areas (in contrast to urban, exurban, and rural areas). Hotspots of coyote conflicts were apparent in the southern region of the DMA, possibly because coyotes had better access to development, and hence interaction with residents, via natural areas bordering urban areas; reporting bias may have also influenced this outcome. Our results will help target management efforts, particularly those focused on people (e.g., education), but also highlight the critical need for improved methods of collecting conflict information via a standardized reporting mechanism to help reduce bias.

This approach, in general, is derived from an implicit stationarity assumption. This paper aims at proving a statistical method that is fully applicable of generating daily precipitation in non-stationary conditions using historical station data. Daily records at five Oklahoma stations were split into calibration and validation periods. Linear relationships between transition probabilities of wet-following-wet (P sub(w/w)) and wet-following-dry (P sub(w/d)) days and mean monthly precipitation were established by connecting the two endpoints (one for the 30 driest months and another for the 30 wettest months of the calibration period) for each calendar month, and were then used to interpolate P sub(w/w) and P sub(w/d) for the validation period. The mean and standard deviation of daily precipitation were estimated using the mean and standard deviation of monthly precipitation of the validation periods as well as the interpolated P sub(w/w) and P sub(w/d). The adjusted parameters were used to generate daily series using a weather generator. Statistics of the disaggregated daily precipitation amounts and frequency, as well as dry/wet spell sequence, agreed with those of the observed values of the validation periods reasonably well. The disaggregation method preserved statistics of monthly precipitation amounts extremely well, demonstrating the validity of the method for temporal disaggregation of non-stationary climate. The accuracy of the presented method is within the weather generator's expected performance. Overall, a straight line connecting the two endpoints, implicitly incorporating non-stationarity of climate states, is adequate for interpolating P sub(w/w) and P sub(w/d) to any climatic conditions within the entire range. However, a linear regression including data points in between would generally improve the P sub(w/w) and P sub(w/d) interpolations slightly if long records (e.g. > 60 years) are available for estimating the intermediate points.

In regions with substantial poultry production, litter application sites are often assumed to be major contributors to bacterial contamination, and grazing lands often receive a similar focus. Since most states use Escherichia coli as an indicator organism for fecal contamination, this study was designed to measure E. coli concentrations in runoff from small agricultural watersheds with various land uses. Specifically, three years of water quality data were collected from 13 watersheds and analyzed to evaluate the impacts of litter application and land use on E. coli concentrations in runoff. In this study, litter application did not impact E. coli concentrations in runoff, which can at least partially be attributed to the late summer target application date. Litter was produced and removed from poultry houses during hot, dry conditions unfavorable for E. coli survival. Thus, late summer application may be a recommended practice to minimize E. coli runoff from litter application sites. Cultivated watersheds with and without litter application produced the lowest E. coli concentrations in runoff, presumably due to limited wildlife presence and livestock exclusion. In contrast, the ungrazed native prairie reference site produced relatively high E. coli concentrations in runoff, presumably due to increased fecal deposition from abundant wildlife. The high concentrations of E. coli from grazed lands emphasize the need for livestock producers to follow best management practice recommendations to minimize bacteria contribution; however, it is important to note that high E. coli concentrations were measured in runoff from well-managed grazing lands as well as ungrazed native prairie, which indicates the difficulty of managing bacterial contamination.

Although simple, the system is exceedingly flexible and allows for household and parcel heterogeneity. We derive an empirical model directly from the structural equations and contrast this using a simulated landscape with the econometric specification most often found in the literature. We then show how the model can be used to project land-use change into the future and for policy simulation. Finally, we use the model to examine the impact of common land conservation policies in Europe. Adapted from the source document.

This study examined the effects of tree- and site-level factors on the mortality of ash trees in stands infested by EAB in OH, USA. Our data show that ash populations in forested sites can progress from healthy to almost complete mortality of mature trees within 6 years. Although the end result of nearly complete mortality does not vary, survival analysis with 5 years of data showed that some factors affected the rate of mortality. We found more rapid mortality in stands with lower densities of ash trees. This finding supports an extension of the resource dilution hypothesis whereby concentration of EAB on few trees in low ash density areas leads to rapid decline of these trees. This contradicts an extension of the resource concentration theory that greater host density increases relative pest abundance and host mortality. Although reductions in ash density via diversification may be desirable for other silvicultural, conservation, and management objectives in preparation for EAB, our study shows that the management strategy of reducing ash density is unlikely to protect the remaining ash trees. Survival analysis also showed that mortality was more rapid for trees shaded by other trees and for trees initially exhibiting dieback. In management scenarios where hazard tree removal must be spread over several years due to budget constraints, focusing initial tree removal on stressed trees is recommended.

Our objective was to examine variation in the diet and use of feeding habitat of four species of gulls, the Laughing (Leucophaeus atricilla), Herring (Larus argentatus), Great Blackbacked (L. marinus), and Ring-billed (L. delawarensis), at a coastal-urban interface. We necropsied, identified the sex and age class, and quantified the stomach contents of 1053 Laughing, 249 Herring, 67 Great Black-backed, and 31 Ring-billed Gulls collected near the New York City metropolitan area in 2003 and 2004. Great Black-backed Gulls specialized on marine foods, whereas Ring-billed Gulls were generalists. Laughing Gulls and Herring Gulls favored marine foods and foraged in marine habitats but also used terrestrial and anthropogenic food sources. We found evidence that demographics influenced the gulls' choice of diet and use of feeding habitat. Laughing Gulls and Herring Gulls switched their use of feeding habitats at various stages of breeding, exploiting terrestrial prey and feeding habitats most during chick rearing. Interspecific and intraspecific differences in the four species' diet and use of feeding habitat apparently allow for their coexistence at this coastal-urban interface.

Since sunn hemp is an under-utilized species, glucose content and agronomic trait variation is essential for the identification of superior sunn hemp accessions for use as potential ethanol for biofuel. Sixteen sunn hemp accessions including the following plant introductions (expressed as glucose concentration) and stem dry weights were studied. "Sixteen sunn hemp accessions including the following plant introductions (expressed as glucose concentration) and stem dry weights were studied." In addition, to verify variability, these traits plus morphological, phenological, and seed reproductive traits were analyzed using multivariate and cluster analysis. The accessions, PI 250487, PI 337080, and PI 219717 produced the highest glucose concentrations (859, 809, and 770 mg g super(-1) stem dry weight, respectively), however PI 468956 produced the highest stem dry weight (258 g). Branching significantly correlated with foliage (r super(2) = 0.67**) and relative maturity (r super(2) = 0.60*), while maturity had a significantly negative correlation with seed number (r super(2) = -0.67**) and plant width (r super(2) = -0.53*) as well. Seed number significantly correlated with plant width (r super(2) = 0.57*). Average linkage cluster analysis grouped the 16 sunn hemp accessions into well-defined phenotypes with four distinct seed-producing groups and one outlier. Based on multivariate and cluster analysis, sufficient variation among these16 sunn hemp accessions exists to support the development of cellulosic ethanol producing cultivars with improved architecture, early maturity, seed yield, glucose concentrations, and stem dry weights.

For mode of action discovery, the strategy for each of these approaches is to generate an omics profile for phytotoxins with known molecular targets and to compare this library of responses to the responses of compounds with unknown modes of action. Using more than one omics approach enhances the probability of success. Generally, compounds with the same mode of action generate similar responses with a particular omics method. Stress and detoxification responses to phytotoxins can be much clearer than effects directly related to the target site. Clues to new modes of action must be validated with in vitro enzyme effects or genetic approaches. Thus far, the only new phytotoxin target site discovered with omics approaches (metabolomics and physionomics) is that of cinmethylin and structurally related 5-benzyloxymethyl-1,2-isoxazolines. These omics approaches pointed to tyrosine amino-transferase as the target, which was verified by enzyme assays and genetic methods. In addition to being a useful tool of mode of action discovery, omics methods provide detailed information on genetic and biochemical impacts of phytotoxins. Such information can be useful in understanding the full impact of natural phytotoxins in both agricultural and natural ecosystems.

The beta -triketone-rich essential oil of Leptospermum scoparium has both preemergence and postemergence herbicidal activity, resulting in bleaching of treated plants and dramatic growth reduction. Radiolabeled leptospermone was synthesized to investigate the in planta mechanism of action of this natural herbicide. Approximately 50 % of the absorbed leptospermone was translocated to the foliage suggesting rapid acropetal movement of the molecule. On the other hand, very little leptospermone was translocated away from the point of application on the foliage, indicating poor phloem mobility. These observations are consistent with the physico-chemical properties of leptospermone, such as its experimentally measured logP and pK sub(a) values, and molecular mass, number of hydrogen donors and acceptors, and number of rotatable bonds. Consequently, leptospermone is taken up readily by roots and translocated to reach its molecular target site. This provides additional evidence that the anecdotal observation of allelopathic suppression of plant growth under beta -triketone-producing species may be due to the release of these phytotoxins in soils.

Interactions between roots of rice and weeds are thought to be modulated by the weed-suppressive activity of some rice cultivars, but these phenomena are difficult to measure and not well understood. Thus, above-ground productivity, weed suppression, and root distribution of 11 rice cultivars and two weed species were evaluated in a drill-seeded, flood-irrigated system at Stuttgart, Arkansas, USA in a two-year study. The allelopathic cultivars, PI 312777 and Taichung Native 1 (TN-1), three other weed-suppressive cultivars, three indica-derived breeding selections, and three non-suppressive commercial cultivars were evaluated in field plots infested with barnyardgrass (Echinochloa crus-galli (L.) Beauv.) or bearded sprangletop (sprangletop, Leptochloa fusca (L.) Kunth var. fascicularis (Lam.) N. Snow). The allelopathic cultivars produced more tillers and suppressed both weed species to a greater extent than did the breeding selections or the non-suppressive cultivars. super(13)C isotope discrimination analysis of mixed root samples to a depth of 15 cm revealed that the allelopathic cultivars typically produced a greater fraction of their total root mass in the surface 0-5 cm of soil depth compared to the breeding selections or the non-suppressive cultivars, which tended to distribute their roots more evenly throughout the soil profile. These trends in root mass distribution were apparent at both early (pre-flood) and late-season stages in weed-free and weed-infested plots. Cultivar productivity and root distribution generally responded similarly to competition with the two weed species, but barnyardgrass reduced rice yield and root mass more than did sprangletop. These findings demonstrate for the first time that roots of the allelopathic cultivars PI 312777 and TN-1 explore the upper soil profile more thoroughly than do non-suppressive cultivars under weed-infested and weed-free conditions in flood-irrigated U.S. rice production systems. They raise the interesting prospect that root proliferation near the soil surface might enhance the weed-suppressive activity of allelochemical exudates released from roots. Plant architectural design for weed suppressive activity should take these traits into consideration along with other proven agronomic traits such as high tillering and yield.

Recent advances in e-nose technologies within the plant sciences, including improvements in gas-sensor designs, innovations in data analysis and pattern-recognition algorithms, and progress in material science and systems integration methods, have led to significant benefits to both industries. Electronic noses have been used in a variety of commercial agricultural-related industries, including the agricultural sectors of agronomy, biochemical processing, botany, cell culture, plant cultivar selections, environmental monitoring, horticulture, pesticide detection, plant physiology and pathology. Applications in forestry include uses in chemotaxonomy, log tracking, wood and paper processing, forest management, forest health protection, and waste management. These aroma-detection applications have improved plant-based product attributes, quality, uniformity, and consistency in ways that have increased the efficiency and effectiveness of production and manufacturing processes. This paper provides a comprehensive review and summary of a broad range of electronic-nose technologies and applications, developed specifically for the agriculture and forestry industries over the past thirty years, which have offered solutions that have greatly improved worldwide agricultural and agroforestry production systems.

The increase in flow resistance at low flows in a plane-bed reach was not fully explained by grain resistance, therefore detailed 3-D velocity measurements were made to investigate spatial variability in velocity and turbulence components and potential controls on flow resistance. One plane-bed reach was surveyed over two stages in Fraser Experimental Forest, Colorado, using a combination of a total station, LiDAR (Light Detection and Ranging), and a SonTek Flowtracker handheld ADV (acoustic Doppler velocimeter). LiDAR was used to capture bank and channel geometry at low flows, whereas the water surface and bed data were collected with the total station at all flows. We used the standard deviation of bed elevation (sigma (sub b) ) within a moving window as an index of roughness height (k (sub s) ) and calculated the relative submergence of the bed at different stages as h/k (sub s) , where h is the local flow depth. ADV measurements were collected on a grid with a 0.3m to 0.5 m spacing. Geostatistical analysis of the velocity data indicated that the flow was highly three-dimensional and varied based on stage, demonstrating that even small irregularities in the bed have a significant influence on the flow characteristics. The streamwise component was the largest at both low and high flow, but varied more throughout the reach at low flow. At high flow, the greatest streamwise velocities were located within the thalweg. Areas of upwelling and downwelling also varied based on stage, with this component being strongly influenced by small changes in the morphology at high flow, and by protuberant grains at low flows. The cross-stream velocity and turbulence components were controlled by the flow structure and less by the roughness of the bed. The turbulence intensity is significant when considering hydraulics for predicting sediment transport and for habitat assessment. The plane-bed flow patterns were compared to results from a pool-riffle reach in the North Fork Cache La Poudre River, a step-pool reach in East St. Louis Creek, and a step-pool reach in Italy on the Rio Cordon. The comparison of the 3-D velocities among channel types showed that the plane-bed reach has higher streamwise velocities, but similar values of cross-stream and transverse velocities. Streamwise turbulence intensities were similar in both the plane-bed and step-pool reach in East St. Louis Creek. The analysis revealed that the connection between the flow characteristics and the channel was not only related to the gross morphology and location of larger clasts, but also to the development of shear layers from the convergence of flow. Therefore, it is essential to understand how water moving in one direction can alter the characteristics of another component of flow and how this interaction is connected to the bed morphology.

CSB soils are generally thicker, less erodible, and contain less clay content than soils found in TB. TB generated significantly more discharge/precipitation ratio than CSB (0.33 vs. 0.24) in the 2009 dormant season. In the 2009 growing season, TB generated significantly less discharge/precipitation ratio than CSB (0.02 vs. 0.07). Over the entire monitoring period, differences in discharge/precipitation ratios between CSB and TB were not significantly different (0.17 vs. 0.20, respectively). Storm-flow rates were significantly higher in TB than CSB in both dormant and growing season. Benthic macroinvertebrate biotic index scores were excellent for all streams. Nutrient concentrations and exports in CSB and TB were within background levels for forests. Low-stream nitrate and ammonium concentrations and exports suggested that both CSB and TB were nitrogen limited. Soils appear to have had a significant influence on seasonal and storm-flow generation, but not on long-term total water yield and water quality under forested conditions. This study indicated that watersheds on TB soils might be more prone to storm-flow generation than on CSB soils when converted from forest to urban. Future urban growth in the area should consider differences in baseline hydrology and effects of landuse change on water quantity and quality.

The relative activities were evaluated using quantitative bactericidal activity [(BA50 value, defined as the percentage of the sample in the assay mixture that resulted in a 50% decrease in colony forming units]. The BA50 values were determined by fitting the data to a sigmoidal curve by regression analysis using concentration-antimicrobial response data. Antimicrobial activity is indicated by a low BA50 value; meaning less material is needed to kill 50% of the bacteria. Olive pomace, olive juice powder, and oregano leaves were active against all 4 pathogens, suggesting that they behave as broad-spectrum antimicrobials. All powders exhibited strong antimicrobial activity against S. aureus. The following powders showed exceptionally high activity against S. aureus (as indicated by the low BA50 values shown in parentheses): apple skin extract (0.002%); olive pomace (0.008%); and grape seed extract (0.016%). Listeria bacteria were also highly susceptible to apple skin extract (0.007%). The most active substances provide candidates for the evaluation of antimicrobial effectiveness in human food and animal feed. Practical Application: Plant-derived health-promoting food supplements, high in bioactive compounds, are candidates for use as antimicrobials in food.

To develop alternatives to conventional insecticides, 24 plant-based essential oils were tested for their acute toxicity against third instars of the Japanese beetle Popillia japonica Newman, European chafer Rhizotrogus majalis (Razoumowsky), oriental beetle Anomala orientalis (Waterhouse), and northern masked chafer Cyclocephala borealis Arrow. Diluted solutions were topically applied to the thorax, which allowed for calculating LD50 and LD90 values associated with 1 d after treatment. A wide range in acute toxicity was observed across all four scarab species. Of the 24 oils tested, allyl isothiocyanate, cinnamon leaf, clove, garlic, and red thyme oils exhibited toxicity to all four species. Allyl isothiocyanate was the most toxic oil tested against the European chafer, and among the most toxic against the Japanese beetle, oriental beetle, and northern masked chafer. Red thyme was also comparatively toxic to the Japanese beetle, oriental beetle, European chafer, and northern masked chafer. Interspecific variability in susceptibility to the essential oils was documented, with 12, 11, 8, and 6 of the 24 essential oils being toxic to the oriental beetle, Japanese beetle, European chafer, and northern masked chafer, respectively. Analysis of the active oils by gas chromatography-mass spectrometry revealed a diverse array of compounds, mostly consisting of mono- and sesquiterpenes. These results will aid in identifying active oils and their constituents for optimizing the development of plant essential oil mixtures for use against scarab larvae.

Therefore, the objective of the current research was to determine if resistance transfers from MDR EC to susceptible strains of inoculated Salmonella. The experiment utilized Holstein calves (approximately 3 weeks old) naturally colonized with MDR EC and fecal culture negative for Salmonella. Fecal samples were collected for culture of Salmonella and MDR EC throughout the experiment following experimental inoculation with the susceptible Salmonella strains. Results initially suggested that resistance did transfer from the MDR E. coli to the inoculated strains of Salmonella, with these stains demonstrating resistance to multiple antibiotics following in vivo exposure to MDR EC. However, serogrouping and serotyping results from a portion of the Salmonella isolates recovered from the calves post-challenge, identified two new strains of Salmonella; therefore transfer of resistance was not demonstrated under these experimental conditions.

To assess chemical residues in domestically marketed catfish products, 1479 catfish samples were collected during the 2008-2010 PDPs. A subset of 202 samples was analysed for 17 toxic polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs). The average pattern of the individual PCDD/F congener concentrations in the catfish was rather unique in that it had almost no measurable amounts of polychlorinated dibenzofurans (PCDFs), but all PCDDs were present. This pattern was more dominant in the domestically produced catfish products than in the imported products (China/Taiwan). Comparison of the pattern to known sources of PCDD/Fs showed strong similarities to the pattern of PCDD/Fs found in kaolin clays which have often been used as anti-caking agents in animal feeds. To investigate whether catfish feeds may be the source of the PCDD/Fs found in the catfish, archived catfish feed data from a US Food and Drug Administration (USFDA) database were examined. In 61 out of 112 feed samples, the PCDD concentrations were 50 times higher than the PCDF concentrations and resembled the pattern found in the catfish products and in clays mined in the south-eastern United States. Although the source of PCDD/Fs in domestically marketed catfish products cannot be definitively established, mined clay products used in feeds should be considered a likely source and, given the wide concentration range of PCDD/Fs that has been found in clays, a critical control point for PCDD/Fs entrance to the food supply.

(L perenne) is a continuous distribution of diameters, or a collection of discrete diameters classes. Methods: Plants from tillers of five clones were grown in a local soil amended with lime. Roots were excavated after they were grown in soil for 54 days, washed and imaged with both a commercial scanner (94 px mm super(-1)) and a high resolution, locally built, imager (204 px mm super(-1)). Images were converted to diameter class length data with WinRhizo. Results: Scanned images did not have enough resolution to accurately measure fine roots diameters (<0.09 mm diam.). Therefore the high resolution images were used. The diameter class length distributions (DCLD) of these images demonstrated diameter class clusters (meso diameter classes) which could be modeled with a non-linear Gaussian (normal) curve model. Recreating the whole root system from a compilation of the DCLD, regenerated from the three parameters of each of the Gaussian curves for the root system, produced a distribution visually identical to the original whole root system curve. Conclusions: L perenne root systems are a collection of meso diameter classes easily described by non-linear Gaussian models. The data set of the parameters from these models is much smaller than a WinRhizo data set, and can reconstruct the original whole system DCLD.

In July 2010. Allium sativum cv. German Extra Hardy Porcelain plants showing foliar symptoms typical of rust infection were brought to the Plant Disease Clinic at the University of Minnesota by a commercial grower from Fill-more County, Minnesota. Infected leaves showed circular to oblong lesions (1 to 3 mm long), which ranged in color from yellow-orange (uredinia) to black (telia). Urediniospores collected from uredinia were globoid to ellipsoid, yellowish in color, and measured 18 plus or minus 1 x 30 plus or minus 2 mu m with a wall thickness of 2.4 plus or minus 0.5 mu m. Teliospores were two celled, 18 plus or minus 3 x 47 plus or minus 10 mu m, with a projected cross-sectional area (1) of 826 plus or minus 87 mu m super(2); cell walls were smooth, brown, 1.6 plus or minus 0.3 mu m (proximal cell) to 2.1 plus or minus 0.5 mu m (distal cell) thick, and 4.2 plus or minus 0.8 mu m at the apex. The pathogen was identified as Puccinia allii (2) and a sample was deposited in the U.S. National Fungus Collection (BPI 884132). DNA was extracted from infected leaf tissue and the nuclear ribosomal internal transcribed spacer region (ITS) and 5' end of the large subunit (LS) was amplified and sequenced as described by Anikster et al. (1). The 1,257-bp sequence from the sample collected in Minnesota (GenBank Accession No. JX402206) was identical to ITS/LS sequence of a sample of P. allii collected from garlic in California (GenBank Accession No. AF511077), with the exception that MN sequence contained nine "A"s rather than 10 in the hyper-variable area at the 3' end of the ITS region. P. allii has been shown to be a species complex comprising at least two different types, "leek type" and "garlic type" (1). Based on the ITS sequence and the projected cross-sectional area of the teliospores, the sample of P. allii from MN is consistent with the garlic type. Garlic rust occurred in localized foci late in the growing season and therefore did not cause significant loss to the 2010 crop. Reoccurrence of garlic rust was not reported in either 2011 or 2012 growing seasons in Minnesota. P. allii all but eliminated commercial garlic-production in California in the late 1990s (1) and has the potential to cause significant negative impact to the emerging garlic crop in Minnesota. However, the epidemiology of garlic rust in the northern U.S. is not well understood and therefore predicting the risk of the Minnesota garlic crop to rust is difficult.

Although the cattle industry is the largest commodity in Montana, no research has been conducted on the abundance, distribution, or impact of stable flies in the state. Observations of stable flies attacking West Nile virus (family Flaviviridae, genus Flavivirus, WNV) -infected pelicans on a refuge in close proximity to pastured and confined cattle provided an opportunity to describe stable fly phenology in a mixed agricultural-wildlife ecosystem. Coroplast cards used to monitor and compare adult populations in three habitats (peninsula, pasture, confinement lot) located within 1.5-4.5 km of each other revealed that temporal dynamics differed by site. Adult abundance was generally lowest at the confinement lot, the only location where larval development was identified. Stable flies were collected on all traps placed in pasture, with traps adjacent to pastured cattle consistently collecting the most. Adults also were collected on the peninsula supporting the pelicans' nesting site, but whether the potential hosts or physical landscape served as an attractant is unclear. At all three sites, data indicated that overwintering was not successful and that a transition occurred from early season immigrating adults that used suitable local larval development substrates to subsequent autochthonous populations.

Using artificial pupal chambers, we documented the time required by teneral adults at three temperatures (20, 25, and 30 degree C), 60-80% RH, and a photoperiod of 16:8 (L:D) h to initiate boring after eclosion and subsequently bore completely through a 7-mm (range, 3-11 mm) layer of Norway maple wood (Acer platanoides L.). In total, 218 laboratory-reared pupae from the Chicago, IL, or Inner Mongolia, China, populations were used in the study. Females (1.54 plus or minus 0.03 g) weighed significantly more than males (1.12 plus or minus 0.03 g), but the average weights of the beetles emerging in each temperature did not differ. Adult weight was positively correlated with exit hole diameter (diameter [mm] = 2.2 * weight [g] + 7.9). The rate at which beetles bored through the wood (136, 178, and 168 mm3/d at 20, 25 and 30 degree C, respectively) significantly differed between temperatures but did not differ with beetle weight. Temperature had a significant effect on the time it took adults to initiate boring (7, 5, and 4 d at 20, 25, and 30 degree C, respectively) and subsequently to complete boring to emerge (5, 4, and 4 d at 20, 25, and 30 degree C, respectively). This suggests that beetles require more than a week to progress from eclosion to emergence in wood, even at summer temperatures. This information on A. glabripennis basic biology is critical for developing phenology models that are used to time exclusion and eradication methodologies.

This strategy has two potential benefits. First, removing infected plants may slow pathogen spread by eliminating inoculum sources. Second, replacing infected plants with uninfected plants may offset yield losses due to disease. The extent to which these benefits are realized depends on multiple factors. In this study, sensitivity analyses of two spatially explicit simulation models were used to evaluate how assumptions concerning implementation of a plant replacement program and pathogen spread interact to affect disease suppression. In conjunction, effects of assumptions concerning yield loss associated with disease and rates of plant maturity on yields were simultaneously evaluated. The first model was used to evaluate effects of plant replacement on pathogen spread and yield on a single farm, consisting of a perennial crop monoculture. The second model evaluated effects of plant replacement on pathogen spread and yield in a 100 farm crop growing region, with all farms maintaining a monoculture of the same perennial crop. Results indicated that efficient replacement of infected plants combined with a high degree of compliance among farms effectively slowed pathogen spread, resulting in replacement of few plants and high yields. In contrast, inefficient replacement of infected plants or limited compliance among farms failed to slow pathogen spread, resulting in replacement of large numbers of plants (on farms practicing replacement) with little yield benefit. Replacement of infected plants always increased yields relative to simulations without plant replacement provided that infected plants produced no useable yield. However, if infected plants produced useable yields, inefficient removal of infected plants resulted in lower yields relative to simulations without plant replacement for perennial crops with long maturation periods in some cases.

It crowds out native plants and hinders water use, causing economic and environmental damage. The leafminer fly Hydrellia sp. 1 (Diptera: Ephydridae), was found feeding in E. densa throughout its Argentine distribution, and is currently the only known specialist herbivore of E. densa. It was reared in the laboratory and tested on 25 plant species. This herbivore can cause heavy defoliation in the laboratory and in the field. Hydrellia sp. 1 was found only on E. densa, but in the laboratory it also developed on two other Hydrocharitaceae species in the same family; Egeria naias, and Elodea callitrichoides. Significant oviposition and feeding were only observed on its primary natural host, and to a lesser degree on E. naias. Field studies indicate Hydrellia sp. 1 is present in the field year round, unless the host plant is prostrate for long periods, or covered by floating macrophytes. These results indicate Hydrellia sp. 1 may be a suitable biocontrol candidate for E. densa.

However, this variation is not congruent with the species phylogeny. This suggests an important role of the environment in shaping the variation in morphology and life histories of this species. As most data on life histories originate from only a small number of populations and do not cover the species' geographic range and phylogenetic diversity, to fill a gap and provide more information for future comparative studies we investigated reproduction and morphology in two montane populations from Slovakia, central Europe. This region is characterized by taxonomic and phylogenetic diversity and both montane and lowland ecological forms of the common lizard occur here. The common lizards from the Slovak populations are sexually dimorphic, with females having larger body and abdomen lengths and males having larger heads and longer legs. Female common lizards start to reproduce at a relatively large size compared to most other populations. This is consistent with a relatively short activity season, which has been shown to be the main factor driving variation in body size in the common lizard. Clutch size was also relatively high and positively correlated with body size, abdomen size and head size. One third of all females attaining the size of the smallest gravid female showed no signs of reproductive activity despite mating opportunities, suggesting that not all females reproduce annually in this population.

Despite widespread redistribution of a number of species, there remains little postrelease data on their establishment and potential effectiveness in many regions. I surveyed parasitoids associated with alfalfa weevil larvae across 30 or more sites in eastern Montana and western North Dakota over 2 yr. Replicate sites were sampled in two habitat types that differ in their physical characteristics, flood-irrigated and dryland alfalfa fields. Irrigated systems are more productive but also more intensively disturbed habitats because of increased harvest frequency and repeated flooding. Given evidence that both habitat disturbance and herbivore density, which often increases with productivity, can influence parasitoid dynamics, I predicted that parasitism levels, the relative importance of different species, or both, would differ across these two system types. Of four larval parasitoid species released previously or recovered in the region, two were found in this study, Bathyplectes curculionis (Thomson) and Oomyzus incertus (Ratzenberg), with average levels of parasitism across habitat types and years of 37.2 and 3.5%, respectively. Parasitism levels differed between habitat types, but the effect was driven by concomitant differences in host densities that were higher in irrigated than dryland fields. Parasitoid responses to host density varied across years and species. B. curculionis exhibited positive density dependence in parasitism across sites in 2009 and negative density dependence in 2010 when host densities were higher regionally. In contrast, O. incertus exhibited positive density dependence in 2010. Our results suggest that these species may be differentially effective at different host densities. Thus, variation in host density could represent an important axis along which parasitoids exhibit spatial complementarity in function.

A. Webb), and three of pistachios (Pistacia vera L.). The proportions of males captured in the different positions were compared with the mean males for all traps, used as an index for abundance. For means between zero and 50 males per trap per week, the distribution was unequal between trap positions and the greatest proportion of males were captured in the northern-most trap (i.e., the within-row direction). Between 50 and 100 males per trap per week, most males were captured in the western-most traps and fewest in the center, and proportions were equal in other trap positions. Above 100 males per trap per week, the proportion of males captured was more nearly equal for all trap positions. These results demonstrate that the sampling range of pheromone traps for navel orangeworm is density dependent and, at low densities, is >400 m. They also indicate that abundance affects the impact of direction (orientation) of trap interference. At low density, female-strength pheromone traps sample males from beyond the block in which they are placed for orchard blocks of <50 ha.

Using high-resolution mass spectroscopy, we determined the structure of the pyoverdine produced by Pf-5. In addition to producing its own siderophores, Pf-5 also utilizes ferric complexes of some pyoverdines produced by other strains of Pseudomonas spp. as sources of iron. Previously, phylogenetic analysis of the 45 TonB-dependent outer membrane proteins in Pf-5 indicated that six are in a well-supported clade with ferric-pyoverdine receptors (Fpvs) from other Pseudomonas spp. We used a combination of phylogenetics, bioinformatics, mutagenesis, pyoverdine structural determinations, and cross-feeding bioassays to assign specific ferric-pyoverdine substrates to each of the six Fpvs of Pf-5. We identified at least one ferric-pyoverdine that was taken up by each of the six Fpvs of Pf-5. Functional redundancy of the Pf-5 Fpvs was also apparent, with some ferric-pyoverdines taken up by all mutants with a single Fpv deletion but not by a mutant having deletions in two of the Fpv-encoding genes. Finally, we demonstrated that phylogenetically related Fpvs take up ferric complexes of structurally related pyoverdines, thereby establishing structure-function relationships that can be employed in the future to predict the pyoverdine substrates of Fpvs in other Pseudomonas spp. JF - Journal of Bacteriology AU - Hartney, Sierra L AU - Mazurier, Sylvie AU - Girard, Maeeva K AU - Mehnaz, Samina AU - Davis, Edward W, II AU - Gross, Harald AU - Lemanceau, Philippe AU - Loper, Joyce E AD - Department of Botany and Plant Pathology, Oregon State University, Corvallis, Oregon, USA, JoyceE.Loper,Joyce.Loper{at}ars.usda.gov.

Increasing phosphate content in media reduced phosphite toxicity. To control green or blue mold, fruit were inoculated with P. digitatum or P. italicum, then immersed 24 h later in KP, calcium phosphite (CaP), sodium carbonate, sodium bicarbonate, or potassium sorbate for 1 min at 20 g/liter for each at 25 or 50 degree C. Mold incidence was lowest after potassium sorbate, CaP, or KP treatments at 50 degree C. CaP was often more effective than KP but left a white residue on fruit. KP was significantly more effective when fruit were stored at 10 or 15 degree C after treatment compared with 20 degree C. Acceptable levels of control were achieved only when KP was used in heated solutions or with fungicides. KP was compatible with imazalil (IMZ) and other fungicides and improved their effectiveness. KP increased thiabendazole or IMZ residues slightly. Phosphite residues did not change during storage for 3 weeks, except they declined when KP was applied with IMZ. KP caused no visible injuries or alteration in the rate of color change of citrus fruit in air or ethylene at 5 mu l/liter.

One common approach for determining corridor locations is least-cost corridor (LCC) modeling, which uses algorithms within a geographic information system to search for routes with the lowest cumulative resistance between target locations on a landscape. However, the presentation of multiple LCCs that connect multiple locations generally assumes all corridors contribute equally to connectivity, regardless of the likelihood that animals will use them. Thus, LCCs may overemphasize seldom-used longer routes and underemphasize more frequently used shorter routes. We hypothesize that, depending on conservation objectives and available biological information, weighting individual corridors on the basis of species-specific movement, dispersal, or gene flow data may better identify effective corridors. We tested whether locations of key connectivity areas, defined as the highest 75th and 90th percentile cumulative weighted value of approximately 155,000 corridors, shift under different weighting scenarios. In addition, we quantified the amount and location of private land that intersect key connectivity areas under each weighting scheme. Some areas that appeared well connected when analyzed with unweighted corridors exhibited much less connectivity compared with weighting schemes that discount corridors with large effective distances. Furthermore, the amount and location of key connectivity areas that intersected private land varied among weighting schemes. We believe biological assumptions and conservation objectives should be explicitly incorporated to weight corridors when assessing landscape connectivity. These results are highly relevant to conservation planning because on the basis of recent interest by government agencies and nongovernmental organizations in maintaining and enhancing wildlife corridors, connectivity will likely be an important criterion for prioritization of land purchases and swaps.Original Abstract: Efectos de los Esquemas de Ponderacion sobre la Identificacion de Corredores para Vida Silvestre Generados con Metodos Menos Costosos La importancia de los corredores para el mantenimiento de la conectividad de metapoblaciones de animales silvestres es una piedra angular de la conservacion. Un metodo comun para la determinacion de localidades para corredores es el modelado de corredores de menor costo (CMC), que utiliza algoritmos en un sistema de informacion geografica para buscar rutas con la menor resistencia acumulativa entre localidades en un paisaje. Sin embargo, la presentacion de multiples CMC que conectan multiples localidades generalmente asume que todos los corredores contribuyen equitativamente a la conectividad, independientemente de la probabilidad de que sean utilizados por animales. Por lo tanto, los CMC pueden sobrestimar rutas largas poco utilizadas y subestimar rutas cortas utilizadas mas frecuentemente. Planteamos la hipotesis de que, dependiendo de los objetivos de conservacion y la informacion biologica disponible, la ponderacion de corredores con base en el movimiento de especies, la dispersion o datos de flujo genico puede identificar corredores efectivos. Probamos si las localidades de las areas de conectividad clave, definida como el 75 degree y 95 degree valor percentil acumulativo ponderado mas alto de aproximadamente 155,000 corredores, cambia bajos diferentes escenarios de ponderacion. Adicionalmente, cuantificamos la cantidad y localizacion de terrenos privados que intersectan areas de conectividad clave en cada esquema de ponderacion. Algunas areas que aparentemente estaban bien conectadas, presentaron mucho menos conectividad cuando fueron analizadas con corredores no ponderados que cuando se usaron esquemas de ponderacion que consideran los corredores con distancias efectivas largas. Mas aun, la cantidad y localizacion de areas de conectividad clave que intersectaron terrenos privados fue variable en los esquemas de ponderacion. Consideramos que las suposiciones biologicas y los objetivos de conservacion deben ser incorporados explicitamente para ponderar corredores cuando se evalua la conectividad del paisaje. Estos resultados son relevantes para la planificacion de la conservacion porque, con base en el reciente interes de agencias gubernamentales y de organizaciones no gubernamentales por mantener e incrementar corredores para vida silvestre, la conectividad sera un criterio importante para la priorizacion de compras e intercambios de tierras.

Since then, multiple articles have investigated avermectins' degradation and its efficacy against a wide variety of pests under different conditions and using different modes of application. However, there is a gap in the literature of analysing abamectin properties and its performance as a non-fumigant nematicide when applied liquid or granular vs. new avenues of application based on seed and seedling treatment.

Barrows (n = 160) were sorted into two treatments at 10 weeks of age (week 0 of the study), and fed growing, grow finishing and finishing diets in 4-week feeding periods. For each feeding phase, diets were prepared without (A-) and with (A+) dietary antimicrobials (chlortetracycline, 0-8 week; bacitracin, 9-12 week) typical of the United States. At week 0, 4, 8, 9, 10 and 12 of the study, faecal swabs or grabs were collected for analyses. Campylobacter spp. was absent at week 0, but prevalence increased over time with most isolates being identified as Campylobacter coli. When chlortetracycline was used in A+ diets (week 4 and 8), prevalence for Campylobacter spp., pathogenic Escherichia coli O26 and stx genes was lower in faeces. On week 12 after the shift to bacitracin, Campylobacter spp. and stx genes were higher in faeces from piglets fed A+ diet. Pathogenic E. coli serogroups O103 and O145 were isolated throughout the study and their prevalence did not differ due to diet. Pathogenic E. coli serogroups O111 and O121 were never found in the piglets, and Salmonella spp. prevalence was low. In production swine, growing diets with chlortetracycline may have reduced pathogen shedding compared with the A-growing diets, whereas finishing diets with bacitracin may have increased pathogen shedding compared with the A-finishing diet. Inclusion of antimicrobials in the diet can affect zoonotic pathogen shedding in faeces of swine.

We evaluated carabid beetle (Coleoptera; Carabidae) responses to operational herbicide and shelterwood seed cut treatments in northern hardwood stands on the Allegheny National Forest, Pennsylvania, USA, from 1992 to 2000. There was substantial defoliation by elm spanworms (Ennomos subsignarius Huebner) or cherry scallopshell moths (Hydria prunivorata Ferguson) during four of the 9years of this study, so we also evaluated effects of these lepidopteran outbreaks on carabids. We found no differences in carabid species richness between herbicide-treated and no herbicide plots overall or in any year, but carabid abundance was higher in herbicide-treated plots in the year following application. Carabid community composition differed among years and increased in dissimilarity over the course of the study but did not differ between herbicide-treated and no herbicide plots. Shelterwood seed cuts had no effects on carabid species richness, abundance or community composition. The relatively few significant effects of experimental treatments on individual carabid species tended to be small and responses we did find differed somewhat from previous studies. In 1992, carabid abundance was significantly correlated with elm spanworm defoliation and in 1995 both species richness and abundance were significantly higher in areas defoliated by cherry scallopshell moth. These results support previous findings that forestry practices that have relatively minor and short-term effects on forest vegetation are unlikely to have substantial effects on carabids; however, natural resource variation resulting from forest lepidopteran outbreaks may have important cascading effects for carabid communities that have not been fully explored.

We conducted a large-scale field study in 2009-2011 (Study 1) to determine the effects of slash scoring (mechanical by chainsaw versus none), slash distribution (scattered versus decked), and cutting date (spring versus fall) on I. perturbatus colonization of and reproductive performance in white spruce, Picea glauca (Moench) Voss, slash, and to determine the effects of resulting treatments on adjacent levels of tree mortality caused by I. perturbatus. Unfortunately, attack densities were lower than expected, and did not provide for a very robust examination of the effects of these treatments. As a result, we reproduced several aspects of Study 1 in a second study (2011) using a baited design. Higher levels of I. perturbatus attack and emergence occurred on dispersed logs. Attack densities were highest in the dispersed, unscored treatment, and similar to 70% higher than observed in the decked, scored treatment. The scoring of dispersed logs significantly reduced attack densities by similar to 28%, but had no effect in decked treatments or on levels of emergence in either treatment. Higher levels of attack and emergence were observed on the tops of logs as compared to the bottoms of logs. Brood production (i.e., defined here as emergence/attacks) was also greater on the tops of logs compared to the bottoms of logs, suggesting the tops of logs are not only more attractive to I. perturbatus, but confer some advantage to brood development. Lower levels of attack and emergence occurred on small diameter logs. Higher levels of attack and emergence were observed on logs in a shaded fuelbreak (i.e., a more open condition of lower tree density) compared to the adjacent forest. Overall, our research suggests that unlike other works on Ips spp. in the western USA that promote the desiccation of slash to minimize colonization and brood production, I. perturbatus appears regulated by the apparency and accessibility of host material. This finding highlights the importance of developing management guidelines based on local science. A third study found two semiochemicals, trans-conophthorin and verbenone, reduced colonization of slash by I. perturbatus, and therefore holds promise as a tool for managing I. perturbatus populations. The implications of these and other results to the management of I. perturbatus in interior Alaska are discussed.

Phloem feeding by beetles disrupts transport of photosynthate from tree canopies and fungi introduced to the tree's vascular system by the bark beetles inhibit water transport from roots to canopy; the implications of these processes for tree mortality are poorly understood. We hypothesized that the fungus must quickly disrupt tree water relations because phloem girdling, reported in other studies, requires much longer than a year to cause mortality. We tested the hypothesis in lodgepole pine (Pinus contorta) by comparing tree water use, foliar expansion and seasonal variation in predawn water potential on 8 mechanically girdled trees, 10 control trees and 17 trees attacked by mountain pine beetle (Dendroctonous ponderosae). Transpiration began to decline within ten days of beetle infestation; two months later, pre-dawn water potential had also dropped significantly as water transport to the canopy declined by 60% relative to healthy trees. There was no water transport or foliar expansion by beetle-infested trees the following year. Experimentally girdled trees continued to transpire, maintain leaf water potential and grow new foliage similar to healthy trees. Our data suggest that fungi introduced by bark beetles in this study are the primary cause of tree mortality following mountain pine beetle attack and significantly reduce transpiration soon after beetle infestation. Rapid decline and the eventual cessation of water uptake by infected trees have important implications for water and nutrient cycling in beetle impacted forests.

The approach does not rely upon quantity sales data and can be applied to any industry that features advertised sales. The results indicate that retailers do compete using promotions. A supermarket promotion in one week significantly increases the probability of a promotion for the same product at rival stores in the following week. Additionally, competitors seek to match or exceed the price cuts of their rivals when responding to promotions. Oligopolistic competition plays a significant role in determining the timing of sales and retail price variation.

AN - 1273585124; 23219611 AB - Nicotinic acetylcholine receptors (nAChRs) are ligand-gated cation channels found throughout the body, and serve to mediate diverse physiological functions. Muscle-type nAChRs located in the motor endplate region of muscle fibers play an integral role in muscle contraction and thus motor function. The toxicity and teratogenicity of many plants (which results in millions of dollars in losses annually to the livestock industry) are due to various toxins that bind to nAChRs including deltaline and methyllycaconitine (MLA) from larkspur (Delphinium) species, and nicotine and anabasine from tobacco (Nicotiana) species. The primary result of the actions of these alkaloids at nAChRs is neuromuscular paralysis and respiratory failure. The objective of this study was to further characterize the motor coordination deficiencies that occur upon exposure to a non-lethal dose of nAChR antagonists MLA and deltaline as well as nAChR agonists nicotine and anabasine. We evaluated the effect of nAChR agonists and antagonists on the motor function and coordination in mice using a balance beam, grip strength meter, rotarod, open field analysis and tremor monitor. These analyses demonstrated that within seconds after treatment the mice had significant loss of motor function and coordination that lasted up to 1 min, followed by a short period of quiescence. Recovery to normal muscle coordination was rapid, typically within approximately 10 min post-dosing.

In total, 133 isolates of P. triticina collected from western Europe, central Europe and Turkey were tested for virulence on 20 lines of wheat with single leaf rust resistance genes, and for molecular genotypes with 23 simple sequence repeat (SSR) markers. After removal of isolates with identical virulence and SSR genotype within countries, 121 isolates were retained for further analysis. Isolates were grouped based on SSR genotypes using a Bayesian approach and a genetic distance method. Both methods optimally placed the isolates into eight European (EU) groups of P. triticina SSR genotypes. Seven of the groups had virulence characteristics of isolates collected from common hexaploid wheat, and one of the groups had virulence characteristics of isolates from tetraploid durum wheat. There was a significant correlation between the SSR genotypes and virulence phenotypes of the isolates. All EU groups had observed values of heterozygosity greater than expected and significant fixation values, which indicated the clonal reproduction of urediniospores in the overall population. Linkage disequilibria for SSR genotypes were high across the entire population and within countries. The overall values of RST and FST were lower when isolates were grouped by country, which indicated the migration of isolates within Europe. The European population of P. triticina had higher levels of genetic differentiation compared to other continental populations.

Due to the complexity of the volatilization process, sophisticated predictive models are needed, especially for dry soil conditions. A mathematical model was developed to allow simulation of the diurnal variation of pesticide volatilization as affected by soil-water content, the air-solid interface partition coefficient, soil-water retention function and soil surface resistance processes. The model formulation considered two possible water retention functions and two soil surface resistance functions. To test the model, simulations were performed for ten successive days of drying under typical semi-arid summer conditions following application of the pesticide diazinon to either a loam or sand soil. Results showed that the temporal variation and magnitude of diazinon emission were strongly affected by the air-solid interface partition coefficient, soil-water content and the surface resistance function. The model was capable of simulating complex diurnal patterns in the peak emission rates which are caused by changes in soil water content and air-solid partitioning. The water retention function formulation had only a minor effect on the simulated water content and volatilization rates, whereas the soil surface resistance function significantly influenced the volatilization rate. Neither the water retention function nor the soil surface resistance formulation had a significant effect on the simulated soil temperature.

Thus, it is necessary to have accurate knowledge of the various physical and chemical mechanisms that affect volatilization rates from field soils. A verification of the influence of soil moisture modeling on the simulated volatilization rate, soil temperature and soil-water content is presented. Model simulations are compared with data collected in a field study that measured the effect of soil moisture on diazinon volatilization. These data included diurnal changes in volatilization rate, soil-water content, and soil temperature measured at two depths. The simulations were performed using a comprehensive non-isothermal model, two water retention functions, and two soil surface resistance functions, resulting in four tested models. Results show that the degree of similarity between volatilization curves simulated using the four models depended on the initial water content. Under fairly wet conditions, the simulated curves mainly differ in the magnitude of their deviation from the measured values. However, under intermediate and low moisture conditions, the simulated curves also differed in their pattern (shape). The model prediction accuracy depended on soil moisture. Under normal practices, where initial soil moisture is about field capacity or higher, a combination of Brooks and Corey water retention and the van de Grind and Owe soil surface resistance functions led to the most accurate predictions. However, under extremely dry conditions, when soil-water content in the top 1 cm is below the volumetric threshold value, the use of a full-range water retention function increased prediction accuracy. The different models did not affect the soil temperature predictions, and had a minor effect on the predicted soil-water content of Yolo silty clay soil.

Despite the development of numerous mathematical models for predicting ammonia emission, the interactions between CO sub(2) emission, manure pH, and ammonia emission are not completely understood. Others have recognized that CO sub(2) emission from manure can increase the surface pH, and so increase the rate of NH sub(3) emission, but this interaction has not been completely described or quantified. In this work, we present a model of simultaneous NH sub(3) and CO sub(2) emission that includes equilibrium acid/base reactions, kinetically-limited CO sub(2) hydration/dehydration reactions, and diffusive transport. Our model accurately predicted the increase in NH sub(3) emission from simple solutions due to CO sub(2) emission, while an equilibrium-only model did not. Model predictions showed that when NH sub(3) and CO sub(2) emission occur simultaneously, CO sub(2) emission generally increases NH sub(3) emission rate by causing an elevation in surface pH. For thin stagnant layers, this response occurs under a wide range of conditions, although the magnitude of the effect is dependent on manure composition, temperature, surface mass transfer coefficient, and other parameters. Kinetically-limited CO sub(2) hydration/dehydration reactions moderate this interaction, so equilibrium-based models tend to over-predict NH sub(3) emission in the absence of significant carbonic anhydrase activity. Predicted emission from deep, mixed manure showed less dependence on CO sub(2) emission, although higher rates of CO sub(2) hydration/dehydration increase this effect. Interactions between CO sub(2) and NH sub(3) emission influence the effect of model parameters on NH sub(3) emission and result in some unexpected responses. Future work should clarify the processes controlling CO sub(2) speciation and transport in manure, including CO sub(2) minerals, bubble transport, and CO sub(2) hydration/dehydration rates. Our model can inform the development of simpler models for estimating NH sub(3) emission, and the design of experiments aimed at quantifying processes that influence NH sub(3) emission from manure. The effects of CO sub(2) on NH sub(3) emission deserve more attention, and both experimental and modeling approaches are needed to understand the interactions that control NH sub(3) emission.

However, there has been little regard to the extreme variation and potential inaccuracies caused by air velocity or sweep air flow rates that are either too low or too high to simulate field conditions. There is a need for correction factors to standardize flux chamber and wind tunnel measurements. In this manuscript, we present results of water evaporative flux and VOC flux measurements with the EPA flux chamber and a small wind tunnel. In the EPA flux chamber, water evaporative flux was positively correlated with sweep air flow rate (SAFR) between 1 and 20 L min-1 (r2 = 0.981-0.999) and negatively correlated with sweep air relative humidity between 0 and 80% (r2 = 0.982-0.992). Emissions of gas-film controlled compounds like NH3 and VOC at AFOs were positively correlated with evaporation rates between 0.6 and 2.8 mm d-1. We demonstrate a simple methodology for standardizing and comparing different chamber types by measuring water evaporation within the chamber using a gravimetric mass balance approach under controlled laboratory conditions. A water evaporative flux ratio correction factor (EFRCF) was used to improve the accuracy of field-measured VOC and NH3 chamber flux measurements. In a field study, both the EPA flux chamber (SAFR = 5 L min-1) and small wind tunnel (SAFR = 1 L min-1) underestimated the true field emissions of VOC, with EFRCFs of 2.42 and 3.84, respectively. EFRCFs are recommended for all but the driest of soil and manure conditions.

Odor emissions from land-applied swine manure may pose a nuisance to downwind populations if manure is not applied with sufficient forethought. A research project was conducted to assess the time decay of odorous volatile organic compound (VOC) emissions following land application of swine manure. Three land application methods were compared: surface application, incorporation 24 h after surface application, and injection. Emission rates were measured in field plots using a small wind tunnel and sorbent tubes. VOCs including eight volatile fatty acids, five aromatics, and two sulfur-containing compounds were quantified by gas chromatography-mass spectrometry. In most cases, a first order exponential decay model adequately described the flux versus time relationship for the 24 h period following land application, but the model sometimes overestimated flux in the 6-24 h range. The same model but with the time term squared adequately predicted flux over the entire 24 h period. Three compounds (4-methylphenol, skatole, and 4-ethylphenol) accounted for 93 percent of the summed odor activity value. First order decay constants (k) for these three compounds ranged from 0.157 to 0.996 h-1. When compared to surface application, injection of swine manure resulted in 80-95 percent lower flux for the most odorous aromatic compounds. These results show that VOC flux decreases rapidly following land application of swine manure, declining below levels of detection and near background levels after 4 to 8 h.

This is due to non-ideal wind conditions, such as those induced by trees and crops surrounding the lagoons, and lagoons with dimensions too small to establish equilibrated microclimate conditions within the water boundary. This study evaluated the accuracy of an emerging backward Lagrangian stochastic (bLS) inverse-dispersion technique to measure lagoon emissions. It used a fabricated floating emission source with known emission rates from an irrigation pond that resembled typical treatment lagoon environments. The measured parameters were wind statistics and downwind path-integrated concentrations. Anemometers were located on the upwind, downwind, or side berm parallel to wind. Additionally, the berm surface was deliberately roughened during the summer by placing pine straw bales along the berms to simulate vegetation growth. Regardless of the surface roughness, when the surrounding vegetation (i.e. corn field) was short during spring and fall, using an anemometer located on the upwind berm produced the most accurate results (0.93 plus or minus 0.19). However, during the summer, the adjacent corn crop grew more than 2 m high. Consequently, the anemometer had to be moved to the side berm. This resulted in a decrease in accuracy to 0.81 plus or minus 0.18. Yet, even with less than idealized conditions, the bLS inverse-dispersion technique still produced reasonably accurate emission rates. This demonstrated the robustness of this easy-to-use bLS inverse-dispersion technique for complex agricultural emission measurements.

Intensive agricultural pesticide use may also challenge these ecosystems. One possible mechanism is pesticide release to the atmosphere after application. The process is enhanced in this region due to the calcareous soils, frequent rainfall, and high humidity and temperatures. This study examined the atmospheric fate of the widely-used insecticide endosulfan. Air samples were collected over a five-year period (2001-2006) at a site within the agricultural community of Homestead, Florida and at sites located in nearby Biscayne and Everglades National Parks (NPs). Mean gas phase air concentrations of alpha -endosulfan were 17 plus or minus 19 ng m super(-3) at Homestead, 2.3 plus or minus 3.6 ng m super(-3) at Everglades NP, and 0.52 plus or minus 0.69 ng m super(-3) at Biscayne NP. Endosulfan emissions from agricultural areas around Homestead appeared to influence air concentration observations at the NP sites. During an intensive sampling campaign, the highest total endosulfan concentrations at the NP sites were observed on days when air parcels were predicted to move from Homestead towards the sampling locations. The alpha -endosulfan fraction ( alpha /( alpha + beta )) was used to examine the contribution of pesticide drift versus volatilization to the overall residue level. The formulated product has an alpha fraction of approximately 0.7, whereas volatilization is predicted to have an alpha fraction of greater than or equal to 0.9. The median alpha - fraction observed during periods of high agricultural activity at Homestead and Everglades NP was 0.84 and 0.88, respectively, and during periods of low agricultural activity the median at Homestead was 0.86, indicating contributions from drift. The median alpha fraction at Everglades NP was 1.0 during periods of low agricultural activity, while Biscayne NP was 1.0 year round indicating air concentrations are primarily influenced by regional volatilization.

Bark samples from treated and untreated trees were collected one day following application and at 4-month intervals for one year. The residual amount of carbaryl was determined, and bark samples were burned to examine the smoke for the active ingredient. Smoke recovered from spiked bark samples showed a very high correlation between the treated rate and the concentration recovered from the smoke. Residual carbaryl on the bark was relatively stable throughout the study and carbaryl was detected in the smoke throughout the duration of the test.

Current efforts to characterize PM emissions from AFOs generally examine variations in mass concentration and particle size distributions over time and space, but these methods do not provide information on the sources of the PM captured. Raman microscopy was employed as a non-destructive method to quantify the contributions of source materials to PM sub(10) emitted from a large cattle feedlot. Raman spectra from potential source materials (dust from unpaved roads, manure from pen surface, and cattle feed) were compiled to create a spectral library. Multivariate statistical analysis methods were used to identify specific groups composing the source library spectra and to construct a linear discriminant function to identify the source of particles collected on PM sub(10) sample filters. Cross validation of the model resulted in 99.76% correct classification of source spectra in the training group. Source characterization results from samples collected at the cattle feedlot over a two-day period indicate that manure from the cattle pen surface contributed an average of 78% of the total PM sub(10) particles, and dust from unpaved roads accounted for an average of 19% with minor contributions from feed. Results of this work are promising and provide support for further investigation into an innovative method to identify agricultural PM sub(10) sources accurately under different meteorological and management conditions.

While mean and median values of O sub(3) concentrations for the 2007 and 2008 summer seasons were similar, maximum O sub(3) concentrations in June and August 2008 were higher than in any month of the 2007 summer season. This increase of maximum concentrations in the high-fire year is attributed to emissions of O sub(3) precursors from wildland fires upwind of DEPO in addition to transport of polluted air from the California Central Valley (CCV) and the San Francisco Bay Area (SFBA). Analysis of backward trajectories for high O sub(3) episodes in June 2007 and 2008 showed the lowest O sub(3) pollution at DEPO when air masses originated over the Pacific Ocean (PO) and passed from West to East over PO and CCV at high altitudes. The highest O sub(3) levels occurred when air masses originated in the vicinity of SFBA, swept through CCV in the NW-SE direction before reaching DEPO at low altitudes. Diurnal O sub(3) concentrations were characterized by a sharp increase early morning and maximum values in late afternoon, followed by gradual evening decreases with very low pre-dawn minima, a phenomenon explained by local generation of O sub(3) combined with the long range transport of polluted air masses from CCV, boundary layer destruction and surface deposition. Once in 2007, and 3 times in 2008, the 8-h average concentration exceeded 75 ppb, counting towards exceedance of the present primary Federal O sub(3) standard (4th highest 8 h concentration <75 ppb over 3 years). The California 8-h average standard (<70 ppb) was exceeded 5 times in 2007 and 6 times in 2008, and these instances counted towards exceedance of the newly proposed primary Federal primary standard (4th highest 8-h concentration <70 ppb over 3 years). In addition, in 2008, the California 1-h average standard (<90 ppb) was exceeded 3 times. The proposed Federal secondary O sub(3) standard of 13 ppm h was exceeded reaching 16 ppm h in 2007 and 15 ppm h in 2008 that indicates potentially phytotoxic effects on local flora.

AN - 1283273562; 23294468 AB - A series of low molecular weight nitro-containing compounds has recently been discovered to have a variety of biological activities including the reduction of anaerobic methane production in ruminant animals and activity against economically important human pathogens, including Salmonella sp. and shigella-toxin producing Escherichia coli . Although some of these nitrocompounds, nitroethane and 2-nitropropane, for example, have been industrial chemicals and synthetic intermediates for years, others such as carboxymethyl nitro-amino acid analogues are new to science and have not been previously described. The purpose of this paper is to review the toxicological profiles, especially as related to events occurring during metabolism and biotransformation, which contribute to toxicological end points of established nitroaliphatic compounds. It is hoped that by summarizing existing knowledge, an understanding of the activities and toxicological profiles of newly established nitrocompounds might be anticipated or adverse events associated with their use might be avoided.

AN - 1273797413; 23265581 AB - Botulinum neurotoxins (BoNTs) are some of the most potent biological toxins. High-affinity monoclonal antibodies (mAbs) have been developed for the detection of BoNT serotypes A and B using a chemiluminescent capture enzyme-linked immunosorbent assay (ELISA). In an effort to improve toxin detection levels in complex matrices such as food and sera, we evaluated the performance of existing antitoxin mAbs using a new electrochemiluminescence (ECL) immunoassay platform developed by Meso Scale Discovery. In side-by-side comparisons, the limits of detection (LODs) observed for ELISA and the ECL immunoassay for BoNT/A were 12 and 3 pg/mL, and for BoNT/B, they were 17 and 13 pg/mL, respectively. Both the ELISA and the ECL method were more sensitive than the "gold standard" mouse bioassay. The ECL assay outperformed ELISA in detection sensitivity in most of the food matrices fortified with BoNT/A and in some foods spiked with BoNT/B. Both the ELISA and the ECL immunoassay platforms are fast, simple alternatives for use in the routine detection of BoNTs in food and animal sera.

The spatial and temporal distribution of stored-product pests was assessed at three food processing facilities using two types of traps and the influence of landscape features on their outside distribution was evaluated. For corrugated traps, targeting walking individuals, placed both inside and outside facilities, the predominant groups, accounting for 59% of captures, were Cryptolestes spp. (Coleoptera: Laemophloeidae), Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae) and Sitophilus spp. (Coleoptera: Curculionidae). Numbers captured in outside corrugated traps tended to be less than captures inside structures, and while level of species diversity was similar fungal feeding species were more common in outside traps. In outside corrugated traps, Cryptolestes spp., Typhaea stercorea (L.) (Coleoptera: Mycetophagidae) and O. surinamensis were most abundant and in outside Lindgren traps that targeted flying individuals, T. stercorea, Cryptolestes spp. and Ahasverus advena (Waltl) (Coleoptera: Silvanidae) were most abundant. No correlation was observed between total captures and species diversity between inside and outside traps. Distribution of stored-product insects in corrugated traps tended not to be spatially clustered (Global Moran's I values ranged from -0.25 to 0.22). However, Anselin local Moran's/indicated that at local level some traps with greatest captures had traps in the vicinity with similar values, but these specific locations were temporally variable. Landscape around each outside corrugated trap was characterized, and increased captures were associated with proximity to grain storage or processing structures, but not with presence of spillage as originally hypothesized. Overall, results support hypothesis that there is considerable movement of insects in landscape surrounding facilities, resulting in limited spatial pattern other than temporally variable hot spots inside or near structures.

In in vitro assays, the compound comprised of PTSO (67 %) and PTS (33 %) dose-dependently killed invasive E. acervulina sporozoites and stimulated higher spleen cell proliferation. Broiler chickens continuously fed from hatch with PTSO/PTS compound-supplemented diet and orally challenged with live E. acervulina oocysts had increased body weight gain, decreased faecal oocyst excretion and greater E. acervulina profilin antibody responses, compared with chickens fed a non-supplemented diet. Differential gene expression by microarray hybridisation identified 1227 transcripts whose levels were significantly altered in the intestinal lymphocytes of PTSO/PTS-fed birds compared with non-supplemented controls (552 up-regulated, 675 down-regulated). Biological pathway analysis identified the altered transcripts as belonging to the categories 'Disease and Disorder' and 'Physiological System Development and Function'. In the former category, the most significant function identified was 'Inflammatory Response', while the most significant function in the latter category was 'Cardiovascular System Development and Function'. This new information documents the immunologic and genomic changes that occur in chickens following PTSO/PTS dietary supplementation, which are relevant to protective immunity during avian coccidiosis.

17365128 AB - We investigated impacts of biocontrol of Tamarix spp. by Diorhabda carinulata on soil nitrogen (N) transformations by surveying organic and mineral soils from three sites. Potential net N mineralization was assayed using laboratory incubations. Results partially supported our hypothesis that herbivory would result in stimulated net N mineralization rates after one year of herbivory exposure, and did not support our hypothesis that herbivory would result in a sustained increase in rates after several years of exposure. Short-term effects differed by site, likely influenced by differences in prevailing soil N status, with net mineralization stimulated at a low fertility site but not at a high fertility site. In the longer-term, there was no impact on overall net N mineralization rates, even though there was a trend towards greater N immobilization in mineral soil. This may result from declining organic matter inputs to soil due to progressive growth limitations from herbivore-induced stress. Results suggest soil N availability will increase in the short-term and eventually decrease in the longer-term at low fertility sites, while soil N availability will not be impacted by herbivory at high fertility sites. Widespread management implications will require further research at sites spanning a range of edaphic characteristics.

KINETICS, THERMODYNAMICS AND ISOTHERM CALCULATIONS AN - 1770353593; 17938259 AB - Batch adsorption experiments were carried out to study the kinetics and thermodynamics of phosphate removal from model solutions on the surface of some selected adsorbents. The data obtained were analysed using two reaction-based kinetic models and a diffusion-based model. In order to examine the extent to which diffusion participates in this adsorption process, the data were processed by the Weber-Morris mass transfer model, respectively. The Freundlich model represented a slightly better description of phosphate adsorption onto Slovakite and GEH super(104) than onto clinoptilolite-rich tuff, while the Redlich-Peterson model yields a better fit for phosphate adsorption onto clinoptilolite-rich tuff. Adsorption onto montmorillonite proceeds best by Sips isotherm model. The calculated AG values show that under the standard conditions the adsorption of phosphate onto all adsorbents examined occurs spontaneously.

The increase in the use of woody biomass as a feedstock for bioenergy production has raised questions about potential impacts on water quality. Best management practices (BMPs) have been developed and implemented since the early 1970s to ensure that forest harvesting can be conducted with minimum impact on water quality. Although BMPs were originally designed to minimize water quality impacts, they can be used for a variety of environmental concerns. The use of BMPs is widespread in developed countries and it varies from mandatory to voluntary. In many countries BMPs are incorporated in 'Codes of Forest Practice' that guide forest managers through the complete bioenergy life cycle. The development and application of BMPs is not a static process, but one that relies on a continual cycle of application, assessment and monitoring, and refinement. Although some countries have "national standards," the complex matrix of forest ecosystems, climates, soils and topography, and harvesting systems requires ongoing assessment, monitoring, and refinement to craft BMPs to best suit local conditions. Research and development studies play a key part in the refinement and communication of improved BMPs. They are also crucial in validating the effectiveness of BMPs. This is especially important where local environmental conditions or operational standards are unique. BMPs ensure that forest bioenergy programs can be a sustainable part of forest management and renewable energy production.

We designed an agent-based spruce budworm flight behavior model that, when interfaced with temperature, wind speed, and precipitation output from a high-resolution atmospheric model, produces detailed flight trajectories and deposition patterns over large landscapes. Rules and relationships describing budworm adult (moth) lift-off, ascent, horizontal flight, and descent were parameterized using a detailed empirical study of budworm dispersal behavior and corresponding meteorological conditions during a 1970s outbreak in New Brunswick, Canada. Simulated moth landings were assumed to be dependent in part on the availability of suitable host tree species. We applied the model to a 6.4million ha landscape at the border between northern Minnesota (USA) and Ontario (Canada) during an eight-day flight window in late June 2007. Specimens collected during and after this flight window indicated moths emerging from an inland source of outbreak populations dispersed over 150km to trap sites near the north shore of Lake Superior, where localized cooling was predicted to have delayed emergence of locally-produced budworm moths. Simulations suggested immigration of moths to lakeshore sites from the outbreak source was plausible on three of eight dates within the flight window, but the relatively narrow deposition footprints implied immigration occurred on different dates across lakeshore sites. Apart from wind speed and direction, precipitation and low temperatures limited dispersal to substantially shorter distances for a few dates within the simulated flight window. Key uncertainties limiting our understanding of atmospheric transport of spruce budworm include behavioral responses to vertical heterogeneity in the air temperature profile, the precipitation threshold required for the forced descent of moths from the air column, and search mechanisms affecting host and/or mate location during long-distance flight.

These processes included coarse (gravel) and fine (silt to sand) tephra fall, a laterally directed blast, fluvial deposition of remobilized tephra, a variety of low-temperature mass-movement processes, and a pyroclastic flow. Each of these geophysical processes constitutes a type of ecosystem disturbance which involves a distinctive suite of disturbance mechanisms, namely burial by tephra and sediment, heating, abrasion, impact force, and canopy loading (accumulation of tephra in tree crowns). Each process affected specific areas, and created patches and disturbance gradients in the forest landscape. Coarse tephra ("gravel rain", >5 cm depth) abraded foliage from tree canopies over an area of approximately 50 km (super 2) north-northeast of the vent. Fine tephra (>10 cm depth) accumulated in tree crowns and led to breakage of branches in old forest and bowing of flexible, young trees over an area of about 480 km (super 2) . A directed blast down the north flank of the volcano damaged forest over an area of 4 km (super 2) . This blast zone included an area of tree removal near the crater rim, toppled forest farther down the slope, and standing, scorched forest around the blast perimeter. Fluvial deposition of >100 cm of remobilized tephra, beginning about 10 days after initiation of the eruption, buried floodplain forest in distinct, elongate streamside patches covering 5 km (super 2) of the lower 19 km of the Rayas River and several km (super 2) of the lower Chaiten River. Across this array of disturbance processes the fate of affected trees varied from complete mortality in the tree removal and pyroclastic flow areas, to no mortality in areas of thin tephra fall deposits. Tree damage included defoliation, loss of branches, snapping of tree trunks, abrasion of bark and ephiphytes, and uprooting. Damaged trees sprouted from epicormic buds located in trunks and branches, but sprouting varied over time among disturbance mechanisms and species. Although some effects of the Chaiten eruption are very similar to those from the 1980 eruption of Mount St. Helens (USA), interactions between biota and geophysical processes at Chaiten produced some unique effects.

A proven biological control agent, the salvinia weevil (Cyrtobagous salviniae Calder and Sands), was field collected on S. minima in Florida, checked for pathogens, and then released in the Preserve from June 2002 through June 2005. Few weevils were recovered from heavily shaded sites when compared to full sun sites where weevils were recovered frequently. Plant biomass and percent cover were reduced only in full sun sites. A field nursery site was established at an undisturbed location in Twin Canals in June 2003 and stocked with 2,421 weevils, released periodically until August 2005. Although weevils, including teneral adults, were recovered at all but one release site, population establishment was not confirmed during this period because of multiple perturbations, culminating in Hurricane Katrina, which caused large scale saltwater intrusion which temporarily destroyed all the sites near the end of the project. However, recent weevil detections by other researchers suggest that the weevils did establish in the area. Any future research efforts in this region should focus on identifying full sun, undisturbed sites to expedite establishment and evaluate impact.

The invasion of Eurasian water-milfoil (Myriophyllum spicatum L.) into a northern California river provides an opportunity to apply predictive relationships for it and its management. To test a hypothesis (from the scientific literature) regarding habitat susceptibility to Eurasian water-milfoil invasion and evaluate prospects for its management, we collected water quality, temperature, and plant data from Fall River. During 2009 and 2010 we determined Eurasian water-milfoil abundance and distribution at 71 locations within the river from an upstream to downstream direction. We also determined water temperature and total phosphorus (P) concentration. The information, in conjunction with simulations from a published model on the weevil/milfoil interaction, suggest that it is not likely that the milfoil weevil will reduce Eurasian water-milfoil biomass in Fall River.

Objective Test the feasibility of Helping HAND (Healthy Activity and Nutrition Directions), an obesity intervention for 5- to 8-year-old children in primary care clinics. Methods A randomized controlled pilot study of Helping HAND, a 6-month intervention, targeted children with body mass index 85-99%tile and their parents. Intervention group attended monthly sessions and self-selected child behaviours and parenting practices to change. Control group received regular paediatric care and was wait-listed for Helping HAND. Session completion, participant satisfaction, child anthropometrics, dietary intake, physical activity, TV viewing and behaviour-specific parenting practices were measured pre and post intervention. Results Forty parent-child dyads enrolled: 82.5% were Hispanic, 80% had a girl and 65% reported income less than or equal to $30000/year. There was 20% attrition from Helping HAND (attended <4/6 sessions). Families self-selected 4.35 (SD 1.75) behaviours to target during the 6-month programme and each of the seven behaviours was selected by 45-80% of the families. There were no between group differences in the child's body mass index z-score, dietary intake or physical activity post intervention. Intervention group viewed 14.9 (SE 2.3) h/week of TV post intervention versus control group 23.3 (SE 2.4) h/week (P < 0.05). Conclusion Helping HAND is feasible, due to low attrition, good programme attendance, and clinically relevant improvements in some child and parenting behaviours.

A cocktail of three lytic phages specific for E. coli O157:H7 (EcoShield(TM)) or a control (phosphate buffered saline, PBS) was applied to lettuce by either; (1) immersion of lettuce in 500 ml of EcoShield(TM) 8.3 log PFU/ml or 9.8 log PFU/ml for up to 2 min before Inoculation with E. coli O157:H7; (2) spray-application of EcoShield(TM) (9.3 log PFU/ml) to lettuce after inoculation with E. coli O157:H7 (4.10 CFU/cm super(2)) following exposure to 50 mu g/ml chlorine for 30 sec. After immersion studies, lettuce was spot-inoculated with E. coli O157:H7 (2.38 CFU/cm super(2)). Phage-treated, inoculated lettuce pieces were stored at 4[degrees]C for and analyzed for E. coli O157:H7 populations for up to 7 d. Immersion of lettuce in 9.8 log PFU/ml EcoShield(TM) for 2 min significantly (p < 0.05) reduced E. coli O157:H7 populations after 24 h when stored at 4[degrees]C compared with controls. Immersion of lettuce in suspensions containing high concentrations of EcoShield(TM) (9.8 log PFU/ml) resulted in the deposition of high concentrations (7.8 log log PFU/cm super(2)) of bacteriophages on the surface of fresh cut lettuce, potentially contributing to the efficacy of the lytic phages on lettuce. Spraying phages on to inoculated fresh cut lettuce after being washed in hypochlorite solution was significantly more effective in reducing E. coli O157:H7 populations (2.22 log CFU/cm super(2)) on day O compared with control treatments (4.10 log CFU/cm super(2)). Both immersion and spray treatments provided protection from E. coli O157:H7 contamination on lettuce, but spray application of lytic bacteriophages to lettuce was more effective In immediately reducing E. coli O157:H7 populations fresh cut lettuce.

Lytic bacteriophages may provide an effective and natural intervention to reduce bacterial pathogens on fresh and fresh-cut produce commodities. The use of multi-phage cocktails specific for a single pathogen has been most frequently assessed on produce commodities to minimize the development of bacteriophage insensitive mutants (BIM) in target pathogen populations. Regulatory approval for the use of several lytic phage products specific for bacterial pathogens such as Escherichia coli O157:H7, Salmonella spp. and Listeria monocytogenes in foods and on food processing surfaces has been granted by various agencies in the US and other countries, possibly allowing for the more widespread use of bacteriophages in the decontamination of fresh and minimally processed produce. Research studies have shown lytic bacteriophages specific for E. coli O157:H7, Salmonella spp. and Listeria monocytogenes have been effective in reducing pathogen populations on leafy greens, sprouts and tomatoes.

Preliminary findings of the surveillance program regarding the circulation of "Nea Santa-Greece-2010" in sentinel chickens were rapidly communicated to public health authorities. In the present article, the full 2011 data produced by this surveillance program are presented. We detected enzootic circulation of WNV in chickens 1 month prior to the onset of the first human cases in 2011. Culex pipiens and Cx. modestus were abundant throughout the sampling period and at all sites of increased transmission. Molecular identification and phylogenetic analysis of WNV isolates from two chickens and one Cx. pipiens mosquito pool suggested that: (1) the virulent "Nea Santa-Greece-2010" WNV lineage 2 strain responsible for the 2010 epidemic was actively circulating in 2011, and (2) all Greek isolates belong to a distinct recent evolutionary clade.

A study was conducted to quantify the role of long-term grazing management to affect CO2 efflux within the semiarid northern Great Plains of North America. Grazing management systems evaluated in the study included two native vegetation pastures differing in stocking rate [moderately grazed pasture (MGP), heavily grazed pasture (HGP)] and a fertilized, grazed crested wheatgrass [Agropyron desertorum (Fisch. ex. Link) Schult.] pasture (CWP) near Mandan, ND, USA. Carbon dioxide efflux was measured on 1-2 week intervals for three years using static chamber methodology. Supplemental assessments of soil temperature and water content, aboveground live biomass, root biomass, and soil microbial biomass C were conducted during each growing season. Carbon dioxide efflux did not differ between native vegetation pastures differing in stocking rate. However, mean hourly CO2 efflux was greater in CWP (100.1mgCm-2 h-1) than HGP (81.1mgCm-2 h-1) (P =0.03), a result attributed to prevalence of cool-season grass and high available N in CWP. Carbon dioxide efflux differed among grazing treatments during spring (March-May) and fall (September-November), but not winter (December-February) and summer (June-August). Associations between CO2 efflux and abiotic factors were seasonally dependent, with positive associations between efflux and soil temperature during spring (r =0.71, P less than or equal to 0.01) and fall (r =0.45, P less than or equal to 0.01) and efflux and water-filled pore space (WFPS) during summer (r =0.46, P less than or equal to 0.01). In this study, increased stocking rate did not contribute to elevated CO2 efflux within native vegetation pastures. Given strong weather-dependence on grassland productivity, long-term monitoring is necessary to confidently discern grazing management effects on C dynamics.

Using disc diffusion and broth microdilution assays we determined higher antibacterial effect of three Salvia spp. and by evaluating the leakage of 260 nm absorbing material we detected effect of extracts and, namely, of essential oils on the disruption of cytoplasmic membrane. The evaluation of in vitro interactions between plant extracts and oxacillin described in terms of fractional inhibitory concentration (FIC) indices revealed synergistic or additive effects of plant extracts and clearly synergistic effects of essential oil from Salvia officinalis with oxacillin in methicillin-resistant Staphylococcus epidermidis .

The AMD poses a serious environmental problem with a negative impact on the surrounding aqueous environment. Heavy metals such as copper, manganese and zinc, were selected from the elements in order to study accumulation properties of the strains isolated from different environments (from weak alkaline pH = 7.7 to ultra acid pH = 3.0 ones). Metal concentrations in live biomass were determined by flame atomic absorption spectrometry. According to the results, bioaccumulation from the AMD was in the order Cu (19 - 31 %) > Zn (10 - 18%) > Mn (5 - 7%). The results indicated removal of substantial amounts of some heavy metals by some of the strains. Changes of pH in the process of heavy metal bioaccumulation were evaluated.

These three key plant species provide information required for the model to be used to classify serai stages and monitor trends based on index values (canopy cover (%) x frequency of occurrence (%)) of the three key plant species. The model is not linear and does not require a straight progression through all serai stages (plant phases) but may go through multiple states. Four serai stages (early to late plant succession) were quantitatively identified with an overall accuracy of serai stage assignment of 93%. All serai stages were significantly different (P = 0.001). Measurements of the three key plant species is all that is required for model prediction and classification of serai stages.

Torr.), western wheatgrass (Pascopyrum smithii (Rydb.) A. Love), and blue grama (Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths) ecological type in central South Dakota. Soils were made up of shallow clay, shallow, shallow porous clay and defined as shallow day soils on the Fort Pierre National Grasslands. Serai stages are quantitatively derived groupings of vegetation composition based on the range of variability within the ecological type. The model is not linear and does not always describe a linear progression through the four serai stages (plant community phases). Instead it provides the quantitative framework for state and transition models. Four ecological serai stages representing early to late succession were identified quantitatively with a classification accuracy of 96%. Information needed to define serai stages and to monitor trends is evaluated with canopy cover and frequency of occurrence data collected for the four common perennial grasses. Index values (canopy cover (%) x frequency of occurrence (%)) for big bluestem, sideoats grama, western wheatgrass, and blue grama are the only measurements required for serai stage classification and monitoring.

Cry1Aa, Cry1Ab and Cry1Ac all bound strongly to the DFTM peritrophic membrane (PM); weaker binding of the Cry1A toxins was observed along the apical brush border of the midgut epithelium. Comparative analysis of the Cry1A toxin-binding molecules in the PM and brush border membrane vesicles (BBMVs) showed that a similar toxin-binding complex was present in both. The Cry1A toxin-binding substance, a broad band with an apparent size of 180kDa, consisted of a closely spaced doublet. The doublet was present in peritrophins, proteins tightly bound to the PM. Lectin binding studies of the PM and BBMV toxin-binding components revealed that they are glyconjugates with terminal alpha -GalNAc residues comprised exclusively of O-linked oligosaccharides in their glycan structures. Mild periodate oxidation, release of O-linked glycans by beta -elimination, and enzymatic removal of terminal alpha -linked GalNAc residues with N-acetyl- alpha -d-galactosaminidase digestion abolished Cry1A toxin-binding to the PM and BBMV components. These data provide strong evidence that O-linked glycans are the target structures on the toxin-binding glycoconjugates for the Cry1A class of insecticidal proteins in DFTM larvae.

AN - 1526735184; 23710543 AB - Integration of behavioral observations with traditional selection schemes may lead to enhanced animal well-being and more profitable forage-based cattle production systems. Brahman-influenced (BR; n = 64) and Gelbvieh × Angus (GA; n = 64) heifers consumed either toxic endophyte-infected tall fescue (E+) or one of two nontoxic endophyte-infected tall fescue (NT) cultivars during two yr. Heifers were weighed at midpoint and termination of grazing. Grazing behavior (grazing, resting in the shade, lying, or standing without grazing) was recorded (n = 13 visual observations per yr in June and July) for each pasture. During yr 2, exit velocity (EV) and serum prolactin (PRL) were determined. Grazing behavior was influenced (P < 0.05) by an interaction between fescue cultivar and breed type. Gelbvieh × Angus heifers assigned to E+ pastures had the lowest percentage of animals grazing and the largest percentage of animals resting in the shade. Brahman-influenced heifers had faster EV (P < 0.001) than GA heifers (0.52 vs. 0.74 ± 0.04 s/m, respectively). Body weight (BW) was affected (P < 0.01) by an interaction of tall fescue cultivar and d, and an interaction of tall fescue cultivar and breed type. Heifers grazing NT pastures were heavier (P < 0.01) than heifers grazing E+ pastures at midpoint and termination. Gelbvieh × Angus heifers grazing NT pastures were heavier (P < 0.01) than GA and BR heifers grazing E+ and BR heifers grazing NT pastures. An interaction of forage cultivar and breed type occurred on serum PRL (P < 0.01). Collectively fescue cultivar, EV, and concentrations of serum PRL were associated with grazing behavior. Heifers grazing NT pastures were observed to be grazing more than heifers assigned to E+ pastures, regardless of breed type, which may have contributed to changes in BW and average daily gain (ADG) in heifers. Integration of behavioral observations along with traditional selection schemes may lead to enhanced animal well-being and more profitable forage-based cattle production systems.

AN - 1500782941; 17958520 AB - Arsenic [As(III), As(V)] phytotoxicity - growth, pigments level reduction, and bioaccumulation in dicotyledonous (Sinapis alba) and monocotyledonous (Triticum aestivum, Hordeum vulgare) crops was determined in the study. As(III) reduced growth and photosynthetic pigments levels more than As(V) and S. alba was the most sensitive from all tested plants. According to the intensity of inhibitory effects tested plants could be arranged in the following rank order: S. alba > H. vulgare > T. aestivum. Observation of arsenic accumulation confirmed prevailing deposition in the roots and poor translocation to the shoots. Translocation was extremely low in monocotyledonous plants. The highest As accumulation and translocation in S. alba fully reflected its highest sensitivity.

We attached satellite transmitters to 18 adult Brown Pelicans (nine males, nine females) that were captured on Grand Isle along the Louisiana coast during 31 August-2 September 2010. Their movements and habitat use were tracked between September 2010 and March 2012. Nine of the Brown Pelicans remained proximate to the Louisiana coast; four ranged along the coasts of Alabama, Mississippi, and Louisiana; three moved from Louisiana to Texas; and two migrated across the Gulf of Mexico to the Yucatan Peninsula. Annual 99% home range estimates varied widely ( x2 = 10,611 km2, SE = 2,370), and males had larger ranges (x2 = 15,088 km2, SE = 2,219) than females (x2 =6,133 km2, SE = 1,764). Habitats used by Brown Pelicans were primarily open water, estuarine emergent wetland, grassland, unconsolidated shore, and deep water habitat types.

Since this research is extended, the overview is limited and highlighting only those results, which concern the surface treated, and thus, the broadened adsorption properties of clinoptilolite-rich tuff incl. the results realized in pilot applications. The zeolite ion exchange pilot installation (ZIEPI) with a hydraulic loading rate of 900 L h super(-1) was situated at the field experimental facility of Water Research Institute in Vajnory, during autumn 1986. Ammonia removal from tannery wastewater using the clinoptilolite-rich tuff with chemical regeneration and regenerant recovery by air stripping was carried out during several months in 1987 at the mixed Wastewater Reclamation Facility in TOMA, Share Holding Company, Otrokovice (Moravia region of former Czechoslovakia).

ER - TY - JOUR T1 - Covariance Structures in Conventional and Organic Cropping Systems AN - 1496881023; 19037526 AB - Guidelines are needed to develop proper statistical analyses procedures and select appropriate models of covariance structures in response to expected temporal variation in long-term experiments. Cumulative yield, its temporal variance, and coefficient of variation were used in estimating and describing covariance structures in conventional and organic cropping systems of a long-term field experiment in a randomized complete block design. An 8-year database on 16 treatments (conventional and organic cropping systems, crop rotations, and tillage) was subjected to geostatistical, covariance structure, variance components, and repeated measures multivariate analyses using six covariance models under restricted maximum likelihood. Differential buildup of the cumulative effects due to crop rotations being repeated over time was demonstrated by decreasing structured and unstructured variances and increasing range estimates in the geostatistical analyses. The magnitude and direction of relationships between cumulative yield and its temporal variance, and coefficient of variation shaped the covariance structures of both cropping systems, crop rotations, and phases within crop rotations and resulted in significant deviations of organic management practices from their conventional counterparts. The unstructured covariance model was the best to fit most factor-variable combinations; it was the most flexible, but most costly in terms of computation time and number of estimated parameters.

Surface seawater was analyzed monthly for 1 year from Kailua-Kona, Hawaii; the Gulf Coast of Alabama; and four sites along the Delaware Bay. Screening for Bacteriovorax was performed on lawns of V. parahaemolyticus host cells. Direct testing of 7.5 mL portions of seawater from the Atlantic, Pacific, and Gulf coasts gave mean annual counts 0.05 ) for Hawaiian seawater. Bacteriovorax counts only correlated with seawater salinity and temperature at one Delaware site ( r=0.79 and r=0.65 , resp.). There was a relatively strong negative correlation between temperature and Bacteriovorax levels ( r=-0.585 ) for Gulf seawater. Selected isolates were sequenced and identified by phylogenetic analysis as Bacteriovorax clusters IX, X, XI, and XII.

Bifidobacteria identified from the honey bee are found in larval guts and throughout the alimentary tract, but attain their greatest abundance in the adult hind gut. To further understand the role of Bifidobacteria in honey bees, we sequenced two strains of Bifidobacterium cultured from different alimentary tract environments and life stages. Results: Reflecting an oxygen-rich niche, both strains possessed catalase, peroxidase, superoxide-dismutase and respiratory chain enzymes indicative of oxidative metabolism. The strains show markedly different carbohydrate processing capabilities, with one possessing auxiliary and key enzymes of the Entner-Doudoroff pathway. Conclusions: As a result of long term co-evolution, honey bee associated Bifidobacterium may harbor considerable strain diversity reflecting adaptation to a variety of different honey bee microenvironments and hive-mediated vertical transmission between generations.

The fish were stocked into twelve 0.264 m super(3) tanks, providing 40 fish per tank with an average density of 18.55 kg/m super(3). Temperature was maintained at 12 degree C and salinity at 2 ppt using ground water during the study. There were no significant differences in specific growth rate (0.62 basal, 0.60 11% BPC, 0.72 22% BPC), feed conversion (1.06, 1.37, 1.09), weight gain (124.3 g, 113.5 g, 155.3 g), proximate composition of the salmon for lipid (8.4%, 7.8%, 9.8%), protein (17.3%, 17.1%, 18.6%), moisture (71.4%, 72.3%, 69.4%), and ash (6.5%, 6.1%, 6.9%) among any of the treatment groups. Salmon fed the diet containing 22% barley protein concentrate, however, had significantly greater energy retention (34%) compared to the fish fed the other diets (23%-28%). The results of this study indicate that barley protein concentrate is an acceptable feed ingredient for Atlantic salmon that should provide performance similar to fishmeal at inclusion rates below 22%.

The soils are fertile loams, but because of the steppe's dry environment, they need to be irrigated. Our objective was to study irrigation management of cotton production on sierozem soils in southern Kazakhstan. From 2006 to 2008, we grew irrigated cotton on low, moderately, and highly saline sierozem soils in the South Kazakhstan Oblast. Soils were irrigated to reduce salinity and improve growth. Yields increased with reduced salinity especially because the highly saline soil could not support growth every year and because it had 33 to 40% less yield when cotton was grown on it. Soils were managed with multiple tillage and cultivations by machinery and hand, which maintained low bulk densities near the surface and a tillage pan at about the 30-cm depth. Future management improvements include fewer tillage operations, which would decrease energy needs and compaction. Reduced upstream salinity would reduce preplanting irrigation needs.

The program suite contains 3 analysis modules along with a fourth control module that can automate analyses of large volumes of data. The modules are used to 1) identify the subset of paired-end sequences that pass Illumina quality standards, 2) align paired-end reads into a single composite DNA sequence, and 3) identify sequences that possess microsatellites (both simple and compound) conforming to user-specified parameters. The microsatellite search algorithm is extremely efficient, and we have used it to identify repeats with motifs from 2 to 25bp in length. Each of the 3 analysis modules can also be used independently to provide greater flexibility or to work with FASTQ or FASTA files generated from other sequencing platforms (Roche 454, Ion Torrent, etc.). We demonstrate use of the program with data from the brine fly Ephydra packardi (Diptera: Ephydridae) and provide empirical timing benchmarks to illustrate program performance on a common desktop computer environment. We further show that the Illumina platform is capable of identifying large numbers of microsatellites, even when using unenriched sample libraries and a very small percentage of the sequencing capacity from a single DNA sequencing run. All modules from SSR_pipeline are implemented in the Python programming language and can therefore be used from nearly any computer operating system (Linux, Macintosh, and Windows).

One of the barriers to practical application of CHS is the fact that trees near the field location of the point-sampling sample point have critical heights that occur quite high on the stem, making them difficult to view from the sample point. To surmount this difficulty, use of the "antithetic variate" associated with the critical height together with importance sampling from the cylindrical shells integral is proposed. This antithetic variate will be u = (1 - b/B), where b is the cross-sectional area at "borderline" condition and B is the tree's basal area. The cross-sectional area at borderline condition b can be determined with knowledge of the HPS gauge angle by measuring the distance to the sample tree. When the antithetic variate u is used in importance sampling, the upper-stem measurement will be low on tree stems close to the sample point and high on tree stems distant from the sample point, enhancing visibility and ease of measurement from the sample point. Computer simulations compared HPS, CHS, CHS with importance sampling (ICHS), ICHS and an antithetic variate (AICHS), and CHS with paired antithetic varariates (PAICHS) and found that HPS, ICHS, AICHS, and PAICHS were very nearly equally precise and were more precise than CHS. These results are favorable to AICHS, since it should require less time than either PAICHS or ICHS and is not subject to individual-tree volume equation bias.Original Abstract: L'echantillonnage de la hauteur critique (EHC) permet d'estimer le volume de bois par unite de surface en multipliant la somme des hauteurs critiques mesurees sur les arbres inventories dans un echantillonnage horizontal par point (EHP) par le facteur de prisme de l'EHP. L'un des obstacles a l'application pratique de l'EHC vient du fait que les arbres proches de l'emplacement du point d'echantillonnage ont des hauteurs critiques qui se situent assez haut sur la tige. Ceci rend les hauteurs critiques difficilement visibles a partir du point d'echantillonnage. On suggere de surmonter cette difficulte en utilisant la > associee a la hauteur critique dans l'echantillonnage par importance basee sur l'integrale d'enveloppes cylindriques. Cette variable antithetique sera u = (1 - b/B) ou b est la section transversale a la limite de demarcation et B est la surface terriere de l'arbre. La section transversale a la limite de demarcation b peut etre determinee avec le facteur de prisme de l'EHP en mesurant la distance de l'arbre echantillonne. Lorsque la variable antithetique u est utilisee dans l'echantillonnage par importance, la mesure en haut de la tige est abaissee pour les arbres proches du point d'echantillonnage et haussee pour les arbres eloignes du point d'echantillonnage. La mesure a partir du point d'echantillonnage se trouve ainsi facilitee par une meilleure visibilite de la hauteur critique. Des simulations sur ordinateur ont permis de comparer l'EHP, l'echantillonnage de la hauteur critique (EHC), l'EHC avec l'echantillonnage par importance (EHCP), l'EHCP avec une variable antithetique (EHCPA) et l'echantillonnage de la hauteur critique avec des variables antithetiques appariees (EHCAA). Les comparaisons ont permis de constater que l'EHP, l'EHCP, l'EHCPA et l'EHCAA avaient pratiquement la meme precision et qu'ils etaient plus precis que l'EHC. Ces resultats privilegient l'EHCPA qui requiert moins de temps que l'EHCAA ou l'EHCP et qui n'est pas sujet au biais de l'equation de volume des arbres individuels.

The entire study sample comprised 341 women ranging in age from 39 to 65 years. The CILP2 genotypes were determined by PCR-RFLP and the ACE genotypes by PCR. The Bonferroni pairwise comparisons showed the effect of the CILP2 genotype on high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein B (apoB), apoB-to-apoA1 ratio, the total cholesterol (TC)-to-HDL-C ratio, non-HDL-C, and the LDL-C-to-HDL-C ratio ( P<0.05 ). Here, higher mean levels of HDL-C and lower mean levels of the remaining above mentioned lipid parameters were registered in the GT/TT genotype carriers than in GG carriers. Statistically significant association was identified between the ACE genotype and the following parameters: TC, LDL-C, and non-HDL-C ( P<0.05 ). The II genotype can lower serum level of TC ( B=0.40 ), LDL-C ( B=0.37 ), and non-HDL-C levels. The results of this study suggest that the minor T allele of CILP2 gene and I allele of ACE gene have a protective effect against elevated serum lipid and lipoprotein levels.

AN - 1468379111; 18740821 AB - Listeria monocytogenes, a major foodborne pathogen, possesses a number of mechanisms that enable it to combat the challenges posed by acidic environments, such as that of acidic foods and the gastrointestinal tract. One mechanism employed by L. monocytogenes for survival at low pH is the adaptive acid tolerance response (ATR) in which a short adaptive period at a nonlethal pH induces metabolic changes that allow the organism to survive a lethal pH. Overcoming acid conditions by L. monocytogenes involves a variety of regulatory responses, including the LisRK 2-component regulatory system, the SOS response, components of the sigma super(B) regulon, changes in membrane fluidity, the F sub(0)F sub(1)-ATPase proton pump, and at least 2 enzymatic systems that regulate internal hydrogen ion concentration (glutamate decarboxylase and arginine deiminase). It is not clear if these mechanisms exert their protective effects separately or in concert, but it is probable that these mechanisms overlap. Studies using mutants indicate that the glutamate decarboxylase system can protect L. monocytogenes when the organism is present in acidic juices, yogurt, salad dressing, mayonnaise, and modified CO sub(2) atmospheres. The glutamate decarboxylase system also has a role in protecting L. monocytogenes against the acidic environment of the stomach. There is a need to study other acid resistance mechanisms of L. monocytogenes to determine their effectiveness in protecting the organism in acidic foods or during transit through the acid stomach.Original Abstract: Listeria monocytogenes, un organisme pathogene alimentaire important, a developpe plusieurs mecanismes qui lui permettent de surmonter les defis que posent les environnements acides comme les aliments acides et l'acidite du tractus gastro-intestinal. Un mecanisme utilise par L. monocytogenes pour sa survie a faible pH consiste en une reponse de tolerance a l'acide (RTA) adaptative dans laquelle une courte periode d'adaptation a un pH non letal induit des changements metaboliques qui permettent a l'organisme de survivre a un pH letal. Surmonter les conditions acides pour L. monocytogenes implique la mise en place d'une variete de reponses regulatrices qui comprennent le systeme regulateur a 2 composantes LisRK, la reponse SOS, les composantes du regulon sigma super(B), les changements de fluidite membranaire, la pompe a proton F sub(0)F sub(1)-ATPase, et au moins 2 systemes enzymatiques qui regulent la concentration interne d'ion hydrogene (glutamate decarboxylase et arginine deiminase). Il n'apparait pas clairement si ces mecanismes exercent leurs effets protecteurs de maniere separee ou de concert, mais il est probable que ces mecanismes se chevauchent. Des etudes realisees avec des mutants indiquent que le systeme de la glutamate decarboxylase peut proteger L. monocytogenes lorsque l'organisme est present dans les jus acides, le yogourt, la vinaigrette, la mayonnaise et dans des atmospheres de CO sub(2) modifiees. Le systeme de la glutamate decarboxylase joue aussi un role dans la protection de L. monocytogenes contre l'environnement acide de l'estomac. Il est necessaire d'etudier d'autres mecanismes de resistance de L. monocytogenes afin de determiner leur efficacite a proteger l'organisme dans les aliments acides ou lors du transit a travers l'estomac.

Nine sites including undisturbed native shrub-steppe and center-pivot-irrigated fields with 1, 2, and 3 years of cultivation following conversion were evaluated. Cultivated fields had greater populations of culturable aerobic and pseudomonad bacteria, greater populations of nitrifying bacteria, increased nitrification potential, greater values of microbial biomass nitrogen (MBN), and different rates of substrate-induced respiration compared to native sites. Disturbance and soil mixing from field development, tillage, irrigation, compost amendments, and residue incorporation contributed to shifts in soil microbial populations and activities following conversion. Differences observed in microbial characteristics were influenced more by conversion of the native ecosystem to an irrigated agroecosystem and the addition of compost than by the length of time of cultivation.

It was deposited on a mica sheet to use as SERS substrate. Fresh cultures of Salmonella Typhimurium, Escherichia coli. Staphylococcus aureus and Listeria innocua were washed from chicken rinse and suspended in 10 ml of sterile deionized water. Approximately 5 mu l of the bacterial suspensions was placed on the substrate individually and exposed to 785 nm HeNe laser excitation. SERS spectral data were recorded over the Raman shift between 400 and 1800 cm super(-1) from 15 different spots on the substrate for each sample; and three replicates were done on each bacteria type. Principal component analysis (PCA) model was developed to classify foodborne bacteria types. PCI identified 96% of the variation among the given bacteria specimen, and PC2 identified 3%, resulted in a total of 99% classification accuracy. Soft Independent Modeling of Class Analogies (S1MCA) of validation set gave an overall correct classification of 97%. Comparison of the SERS spectra of different types of gram-negative and gram-positive bacteria indicated that all of them have similar cell walls and cell membrane structures. Conversely, major differences were noted around the nucleic acid and amino acid structure information between 1200 cm super(-1) and 1700 cm super(-1) and at the finger print region between 400 cm super(-1) and 700 cm super(-1). Silver biopolymer nanoparticle substrate could be a promising SERS tool for pathogen detection. Also this study indicates that SERS technology could be used for reliable and rapid detection and classification of food borne pathogens.

Our objectives were to characterize crown rot severity and distribution throughout the PNW by conducting a survey of 210 fields covering the diverse dryland wheat-producing areas of Washington and Oregon and to utilize a factor analysis statistical approach to determine the effects of climate and geography on species distribution and disease severity. Climatic variables were based on 30-year averages and 2008 and 2009 separately (the 2 years of the survey). Mean annual temperature, mean temperature in the coldest month, mean temperature in the warmest month, mean annual precipitation, snowfall, elevation, soil type, and cropping intensity were highly intercorrelated. The factor analysis of the climate variables resulted in the development of two latent factors that could be used as predictor variables in logistic regression models for the presence or absence of Fusarium spp. and of FCR disease scores. Isolates of Fusarium spp. were recovered from 99% of 105 fields sampled in 2008 and 97% of fields in 2009. There were differences between years for responses of FCR and nodes scores, and isolations of Fusarium pseudograminearum with more significant results in 2008, due to warmer drier weather. Results of the factor analysis showed that the distribution of F. pseudograminearum occurred in a greater frequency in areas of the PNW at lower elevations with lower moisture and higher temperatures in 2008, whereas F. culmorum occurred in greater frequency in areas at higher elevations with moderate to high moisture and cooler temperatures consistently across both years. Disease scores increased with increasing levels of factors 1 (primarily temperature) and 2 (primarily precipitation). Both the frequency of pathogen species and disease scores were influenced by the year, indicating that soilborne pathogens are responsive to short-term changes in environment. This factor analysis approach can be utilized in studies to determine the effects of climate and other environmental (soil, cropping system, and so on) factors on the distribution and severity of root diseases.

Runoff samples from irrigation furrows were each split into four volumes: two were filtered (45 mu m) in the field and two were filtered 10 days later, with or without boric acid treatment, and stored at 4 degree C. Sample dissolved reactive P (DRP), nitrate nitrogen (NO sub(3)-N), and ammonium (NH sub(4))-N concentrations were measured in all filtered samples 10 and 107 days after collection. Samples filtered in the field and those with a 10-day delayed filtration had similar dissolved DRP, NO sub(3)-N, and NH sub(4)-N concentrations, whether or not boric acid was added. Boric acid stabilized DRP and NH sub(4)-N sample concentrations, but not NO sub(3)-N, during the 107 days of storage (relative to field-filtered samples). The effect of treatments on computed furrow stream concentration and runoff mass losses was similar to that for sample concentrations, except that furrow NH sub(4)-N parameters were unaffected by treatments. The field-filtered or 10-d delayed filtration without boric acid treatments provided the best dissolved nutrient measurements for comparing agricultural management effects at the field edge; however, results suggest that an incubation-type test for field-edge runoff water may provide a more accurate estimate of field management effects on dissolved nutrient loads in downstream aquatic ecosystems.

There is no question that our relationship with wilderness has changed. Individually it is probably quite easy to examine differences in the role wilderness plays in the quality of our lives today compared to some previous time. But how the role of wilderness protection has changed for society is more difficult to describe. In only a few places do we have data across multiple decades that would allow us to even examine how users or their use may have changed over time. At the Boundary Waters Canoe Area Wilderness in northern Minnesota we are fortunate to have multiple studies that can give us some 40 years of insight into how some aspects of use have changed there. For example, an analysis of results of visitor studies at the Boundary Waters Canoe Area Wilderness in 1969, 1991 and 2007 reveal some big differences in who is out there today, most notably the presence of a much older, more experienced and better educated user population, almost exclusively white and predominantly male. It is time to decide whether the best thing for wilderness and or society is to try to restore historic patterns of use (to include younger people, the less wealthy and lower educated) in greater numbers, to try to identify new markets within growing underrepresented populations, or adapt our perception of wilderness stewardship to better include planning for emerging social values of a new generation with other indicators of well-being. A growing population with greater dependence on ecosystem services provided by protected nature could lead to wilderness protection becoming an important quantitative and qualitative element of quality of life indices in the very near future.

Design/methodology/approach -- Mixed quantitative and qualitative methods were deployed. Semi-structured interviews were used to collect qualitative and quantitative data from 100 farmers in three selected wards in Chamwino district in Tanzania. Focus groups were also used to collect qualitative data from 30 farmers in the same wards. Findings -- The results showed that the major sources of information for farmers were predominantly local (neighbours and friends), followed by public extension services. Apart from radio and cell phones, advanced technologies (i.e. internet and e-mail) and printed materials were not used in the study area, despite their existence in the communities. Research limitations/implications -- The study necessitates a need to conduct regular studies on preferred information source of agricultural information and knowledge, development of technologies and use multiple sources of knowledge and information (such as print and mass media) to deliver relevant information to farmers to enable them to adapt to climate change. Originality/value -- The study provides a deep understanding of sources of agricultural information used by farmers in the semi-arid area, which necessitates a need for demand-led and client-based information services, in order to meet the disparate farmers' needs in this regime of climate change. These findings can serve as an example for the increasing use of mixed quantitative and qualitative in information research. Adapted from the source document.

Incorporation of green manures into soil increases population density of streptomycetes with broad pathogen antagonist activity. This study aimed to measure the impact of wheel traffic on forage yield and plant health and the effect of green manures to reduce disease. Buckwheat and sorghum-sundangrass were incorporated into soil 3 weeks before seeding alfalfa. Total bacteria, streptomycete, and pathogen antagonist densities were measured prior to planting green manures and alfalfa. Wheel traffic was applied 2 days after each forage harvest. Wheel traffic reduced forage yield 12 % to 17 % depending on year and location, significantly reduced plant counts, and increased crown rot compared to the no traffic control. Cultivar had a significant effect on yield, plant counts, and crown rot. Streptomycete density and pathogen antagonists increased when fall-sown green manure crops were incorporated in spring. Forage yields were significantly higher in plots with greater antagonist density when traffic was applied. Green manure treatments did not affect plant counts or crown rot. Mechanical wheel traffic reduces forage yield and increases disease. Green manure crops may provide benefits in alfalfa production systems by increasing pathogen antagonists.

Methods: Two montane sites in the western Cascade Mountains of Oregon with adjacent areas of forest and meadow vegetation were studied. A reciprocal transplant experiment evaluated both minor (soil cores remaining in the same vegetation type) or more severe disturbance (soil cores transferred to a different vegetation type). The biomass and composition of the bacterial and fungal communities were measured for 2 years following the establishment of the experiment. Results: Minor disturbance (coring) had little impact on microbial biomass but transferring between vegetation type showed greater fungal biomass in soil incubated in the forest environment. The composition of bacterial communities was not influenced by coring but responded strongly to transfers between vegetation sites, changing to reflect their new environment after 2 years. Fungal community composition responded somewhat to coring, probably from disrupting mycorrhizal fungal hyphae, but more strongly to being transferred to a new environment. Conclusions: The response of the microbial community to major disturbance was rapid, showing shifts reflective of their new environment within 2 years, suggesting that microbial communities have the capacity to quickly adjust to catastrophic disturbances.

DO - http://dx.doi.org/10.1007/s11104-013-1760-7 ER - TY - JOUR T1 - Psychometric assessment of scales for a Model of Goal Directed Vegetable Parenting Practices (MGDVPP) AN - 1458538453; 18746227 AB - Background: Vegetable intake has been related to lower risk of chronic illnesses in the adult years. The habit of vegetable intake should be established early in life, but many parents of preschoolers report not being able to get their child to eat vegetables. The Model of Goal Directed Behavior (MGDB) has been employed to understand vegetable parenting practices (VPP) to encourage a preschool child's vegetable intake. The Model of Goal Directed Vegetable Parenting Practices (MGDVPP) provides possible determinants and may help explain why parents use effective or ineffective VPP. Scales to measure effective and ineffective vegetable parenting practices have previously been validated. This manuscript presents the psychometric characteristics and factor structures of new scales to measure the constructs in MGDVPP. Methods: Participants were 307 parents of preschool (i.e. 3 to 5 year old) children, used for both exploratory (EFA) and confirmatory factor analyses (CFA). Data were collected via an internet survey. First, EFA were conducted using the scree plot criterion for factor extraction. Next, CFA assessed the fit of the exploratory derived factors. Then, classical test theory procedures were employed with all scales. Finally, Pearson correlations were calculated between each scale and composite effective and ineffective VPP as a test of scale predictive validity. Results: Twenty-nine subscales (164 items) within 11 scales were extracted. The number of items per subscale ranged from 2 to 13, with three subscales having 10 or more items and 12 subscales having 4 items or less. Cronbach's alphas varied from 0.13 to 0.92, with 17 being 0.70 or higher. Most alphas <0.70 had only three or four items. Twenty-five of the 29 subscales significantly bivariately correlated with the composite effective or ineffective VPP scales. Discussion: This was the initial examination of the factor structure and psychometric assessment of MGDVPP scales. Most of the scales displayed acceptable to desirable psychometric characteristics. Research is warranted to add items to those subscales with small numbers of items, test their validity and reliability, and characterize the model's influence on child vegetable consumption.

To assess the genetic diversity and population structure in Gossypium species, 111 cotton accessions representing five allotetraploids (AD sub(1)-AD sub(5) genomes), 23 Asiatic diploids of the Old World (A sub(1) and A sub(2) genomes), and 82 diploids of the New World subgenus Houzingenia (D sub(1)-D sub(11) genomes) species were assessed using simple sequence repeats (SSR) markers with wide genome coverage. The mean genetic distance (GD) between the two most important New World tetraploid cottons (Upland (Gossypium hirsutum L.) and Pima (Gossypium barbadense L.)) was 0.39. Among the three shrub type sections (Houzingenia, Integrifolia, and Caducibracteolata) and three arborescent sections (Erioxylum, Selera, and Austroamericana), the GD ranged between 0.19 and 0.41. Phylogenetic analyses clustered all species into distinct phylogenetic groups, which were consistent with genomic origin, evolutionary history, and geographic distribution or ecotypes of these accessions, suggesting the existence of clear structured strata. With all of the genomes, the highest statistical analysis of Structure test through measurements of ad hoc ( Delta K) occurred at K = 2, with group Q1 with the Old World diploid A genomes and with group Q2 with all the New World diploids of the D genome. AD genome accessions shared nearly equal alleles from both Q1 and Q2 groups. With all of the diploids of the New World D genomes, the highest value of Delta K occurred at K = 5. These results are consistent with the fundamental knowledge of tetraploid AD-genome formation and the rapid radiation of the American diploid cotton linage that took place somewhere in southwestern Mexico, followed by a differentiation-speciation during angiosperm evolution. In addition, SSR markers provide an alternative solution for distinguishing phylogenetic relationships between accessions of different ecotypes and for elucidating population structure of cottons of the New World.Original Abstract: Une analyse globale de la diversite genetique du coton (Gossypium spp.) constitue un premier pas pour en comprendre la distribution, la dissemination, la parente genetique et la structure des populations. Pour evaluer la diversite genetique et la structure des populations, en utilisant les marqueurs a large couverture genomique des especes, les auteurs ont etudie 111 accessions representant cinq especes allotetraploides (genomes AD sub(1)-AD sub(5)), 23 diploides asiatique de l'Ancien Monde (genomes A sub(1) and A sub(2)), et 82 diploides du Nouveau Monde du sous-genre Houzingenia (genomes D sub(1)-D sub(11)). La distance genetique moyenne (DG) entre les deux cotons tetraploides les plus importants du Nouveau Monde (hautes terres (Gossypium hirsutum L.) et Pima (Gossypium barbadense L.) est de 0.39. Parmi les trois sections arbustives (Houzingenia, Integrifolia, et Caducibracteolata) et les trois sections arborescentes (Erioxylum, Selera, et Austroamericana), la DG va de 0.19 a 0.41. Les analyses phylogenetiques regroupent toutes ces especes en groupes phylogenetiques distincts, ce qui est congru avec l'origine genomique, l'histoire evolutive et la distribution geographique ou les ecotypes de ces accessions, ce qui suggere l'existence d'une nette structure stratifiee. Pour l'ensemble des genomes, l'analyse statistique de structure la plus elevee de la mesure ad hoc ( Delta K) survient a K = 2), dans le groupe Q1 chez les genomes diploides A de l'Ancien Monde et dans le groupe Q2 chez les diploides du genome D de l'Ancien Monde. Les accessions du genome AD partagent presque egalement les alleles a la fois des groupes Q1 et Q2. Avec l'ensemble des genomes diploides D du Nouveau Monde, la plus haute valeur de Delta K survient a K = 5. Ces resultats sont congrus avec la connaissance fondamentale de la formation des genomes tetraploides AD et la rapide radiation de la lignee diploide americaine ayant eu lieu quelque part dans le sud-ouest du Mexique, suivie d'une differenciation-speciation au cours de l'evolution des angiospermes. De plus, les marqueurs SSR fournissent une solution alternative pour distingue les relations phylogenetiques entre les accessions de differents ecotypes et pour elucider la structure des populations de coton du Nouveau Monde.

In eastern North America, the characteristics of many presettlement fire regimes are unclear because of the passage of time. To help clarify this situation, we developed a 435-year fire history for the former conifer forests of northern Pennsylvania. Ninety-three cross sections of fire-scarred red pines (Pinusresinosa Aiton) collected from three sites were analyzed to determine common fire regime characteristics. Prior to European settlement, fires occurred every 35-50 years and were often large dormant-season burns that sometimes initiated red pine regeneration. American Indians probably ignited these fires. Fire occurrence had a weak association with multiyear droughts. After European settlement started around 1800, fires occurred every 5-7 years due to widespread logging. Fire size and seasonality expanded to include small growing-season fires. The weak drought-fire association ceased. In the early 1900s, logging ended and wildfire control began. Since then, fires have been nearly absent from the sites despite several multiyear droughts in the 20th century. The human influences of cultural burning, logging, and fire exclusion are more important than the influence of drought to the fire regimes of northern Pennsylvania.Original Abstract: Il est necessaire de comprendre les regimes des feux passes pour justifier et proceder a la restauration des forets dont l'origine est due a des perturbations via des programmes de brulage dirige. Dans l'est de l'Amerique du Nord, on connait mal les caracteristiques de plusieurs regimes des feux anterieurs a la colonisation parce qu'ils remontent loin dans le temps. Pour aider a clarifier cette situation, nous avons elabore un historique des feux etale sur 435 ans pour les anciennes forets de coniferes de la Pennsylvanie. Quatre-vingt-treize sections radiales de pin rouge (Pinus resinosa Aiton) portant des cicatrices de feu ont ete recoltees dans trois stations et ont ete analysees pour determiner les caracteristiques communes des regimes des feux. Avant la colonisation par les europeens, les feux survenaient tous les 35 a 50 ans, durant la saison dormante; ils etaient souvent vastes et declenchaient parfois la regeneration du pin rouge. Ces feux etaient probablement allumes par les amerindiens. L'occurrence des feux etait faiblement associee a des periodes de secheresse qui duraient plusieurs annees. Apres le debut de la colonisation par les europeens vers 1800, les feux survenaient a tous les 5 a 7 ans a cause des coupes qui etaient tres repandues. La taille des feux a augmente et leur caractere saisonnier s'est developpe pour inclure de petits feux durant la saison de croissance. La relation faible qui avait ete notee entre la secheresse et le feu a disparu. Au debut des annees 1900, les coupes ont cesse et la suppression des feux de foret a debute. Depuis, il n'y a pratiquement pas eu de feux dans les stations qui faisaient partie de l'etude bien que plusieurs periodes de secheresse etalees sur plusieurs annees soient survenues au cours du 20 super(e) siecle. L'influence de l'homme via le brulage culturel, la coupe et l'exclusion du feu est plus importante que l'influence de la secheresse sur les regimes des feux dans le nord de la Pennsylvanie.

Scale serves as an abstract concept, providing a framework for organizing observations and theoretical models, and plays a functional role in the organization of ecological communities and physical processes. Rich methodological resources are available to plant pathologists interested in considering either or both aspects of scale in their research. We summarize important concepts in both areas of the literature, particularly as they apply to the spatial pattern of plant disease, and highlight some new results that emphasize the importance of scaling on the emergence of different types of probability distribution in empirical observation. We also highlight the important links between heterogeneity and scale, which are of central importance in plant disease epidemiology and the analysis of spatial pattern. We consider statistical approaches that are available, where actual physical scale is known, and for more conceptual research on hierarchies, where scale plays a more abstract role, particularly for field-based research. For the latter, we highlight methods that plant pathologists could consider to account for the effect of scale in the design of field studies.

With a few exceptions, these systems typically do not have direct sustained use by growers. Rather, their impact is mostly pedagogic and indirect, improving recommendations from farm advisers and shaping management concepts. The degree to which a system is consulted depends on the amount of perceived new, actionable information that is consistent with the objectives of the user. Often this involves avoiding risks associated with costly disease outbreaks. Adoption is sensitive to the correspondence between the information a system delivers and the information needed to manage a particular pathosystem at an acceptable financial risk; details of the approach used to predict disease risk are less important. The continuing challenge for researchers is to construct tools relevant to farmers and their advisers that improve upon their current management skill. This goal requires an appreciation of growers' decision calculus in managing disease problems and, more broadly, their overall farm enterprise management.

Seed transfer zones based on genetic variability and climate were developed using tapertip onion (Allium acuminatum Hook.) collected in the Great Basin and surrounding areas in the United States. Bulbs from 53 locations were established at two common garden sites and morphological (such as leaf and scape dimensions), phenological (such as bolting date and flowering), and production traits (such as emergence and seeds per plant) were measured. Differences among source locations for plant traits within both common gardens were strong (P < 0.001), indicating genetic variation. Principal component 1 (PC 1) for phenological traits, with R super(2) = 0.59, and PC 1 for production traits, with R super(2) = 0.65, were consistently correlated with annual, maximum, minimum, and average temperature, annual precipitation, and frost-free days at source locations (P < 0.05). Regression of PC 1 phenology and PC 1 production scores with source location climates resulted in models with R super(2) values of 0.73 and 0.52, respectively. Using a geographic information system, maps of these models were overlaid to develop proposed seed zones to guide the choice of germplasm for conservation and restoration of tapertip onion across the collection region.Original Abstract: Le choix des germoplasmes revet une importance critique pour la restauration durable : pourtant, les lignes directrices pour le transfert des semences font defaut, a quelques exceptions pres, pour l'ensemble des especes herbacees. Les auteurs ont developpe des zones de transfert des semences basees sur la variabilite genetique et le climat, en utilisant l'oignon acumine (Allium acuminatum Hook.) recolte a Grand Basin et ses environs, aux Etats-Unis. Ils ont plante des bulbes provenant de 53 localites sur le site de deux jardins communs et ils ont mesure les traits morphologiques (tels que les dimensions des feuilles et des hampes), phenologiques (tels que la date de floraison et la montee a graines) et les caracteres de production (tels que l'emergence et le nombre de graines par plant). Les differences entre les localites d'origine pour les traits des plantes a l'interieur des deux jardins communs sont robustes (P < 0,001), traduisant la variation genetique. L'analyse en composantes principales 1 (PC 1) pour les traits phenologiques, avec R super(2) = 0,59, et PC 1 pour les traits de production, avec R super(2) = 0,65, montre une correlation congrue avec les temperatures, annuelles, maximales, minimales et moyennes, la precipitation annuelle ainsi que le nombre de jours sans gel sur la localite des sources (P < 0,05). La regression du PC 1 sur la phenologie et le PC 1 des donnees de production, avec les climats des localites d'origine, conduit a des modeles ayant des valeurs de 0,73 et 0,52, respectivement. En utilisant le systeme d'information geographique, on a superpose la carte de ces modeles afin de proposer des zones de semences pour guider le choix des germoplasmes en vue de la restauration et la conservation de l'oignon acumine, sur l'ensemble de l'aire des recoltes.

Ant tending had sex-dependent effects on most measures of larval growth: female larvae generally benefitted from increased tending frequency whereas male larvae were usually unaffected. The larger size of female larvae tended by ants resulted in a substantial predicted increase in lifetime egg production. Oviposition by adult females that were tended by C. floridanus ants as larvae was similar between host plants with or without ants. However, they laid relatively more eggs on plants with ants than did females raised without ants, which laid less than a third of their eggs on plants with ants present. In summary, we found conditional benefits for larvae tended by ants that were not accompanied by oviposition preference for plants with ants present, which is a reasonable result for a system in which ant presence at the time of oviposition is not a reliable indicator of future ant presence. More broadly, our results emphasize the importance of considering the consequences of variation in interspecific interactions, life history traits, and multiple measures of performance when evaluating the costs and benefits of mutualistic relationships.

Babesiosis is transmitted to cattle through the bite of infected cattle ticks of the genus Rhipicephalus. The most prevalent species is Rhipicephalus (Boophilus) microplus, which is distributed throughout the tropical and subtropical countries of the world. The transmission of B. bovis is transovarian and a previous study of the R. microplus ovarian proteome identified several R. microplus proteins that were differentially expressed in response to infection. Through various approaches, we studied the reaction of the R. microplus ovarian transcriptome in response to infection by B. bovis. Methods: A group of ticks were allowed to feed on a B. bovis-infected splenectomized calf while a second group fed on an uninfected splenectomized control calf. RNA was purified from dissected adult female ovaries of both infected and uninfected ticks and a subtracted B. bovis-infected cDNA library was synthesized, subtracting with the uninfected ovarian RNA. Four thousand ESTs were sequenced from the ovary subtracted library and annotated. Results: The subtracted library dataset assembled into 727 unique contigs and 2,161 singletons for a total of 2,888 unigenes, Microarray experiments designed to detect B. bovis-induced gene expression changes indicated at least 15 transcripts were expressed at a higher level in ovaries from ticks feeding upon the B. bovis-infected calf as compared with ovaries from ticks feeding on an uninfected calf. We did not detect any transcripts from these microarray experiments that were expressed at a lower level in the infected ovaries compared with the uninfected ovaries. Using the technique called serial analysis of gene expression, 41 ovarian transcripts from infected ticks were differentially expressed when compared with transcripts of controls. Conclusion: Collectively, our experimental approaches provide the first comprehensive profile of the R. microplus ovarian transcriptome responding to infection by B. bovis. This dataset should prove useful in molecular studies of host-pathogen interactions between this tick and its apicomplexan parasite.

Terrestrial mollusks near logged streams with similar to 15 m fixed-width buffers were compared to logged streams with no buffers and to unlogged controls. Mollusk communities varied among sites relative to vegetative composition, the amount of understory cover and presence of seeps or small wetland features in the riparian areas. After logging, slug and snail abundance were significantly different between streams with no buffers compared to fixed-width buffers and control streams, however the effect size was relatively small suggesting site variability may override the effects of logging. Our findings illustrate that site variability can affect mollusk community structure and influence taxa resiliency to disturbances such as logging.

In forestry, it is an important silvicultural concept for maintaining stand health in the face of climate change and biotic stress, but uncertainty exists because traditional self-thinning limits were set subjectively without regard to site quality. We addressed this by analyzing ponderosa pine (Pinus ponderosa Lawson & C. Lawson) data from 109 research plots measured repeatedly and 59 inventory plots measured once across California. Self-thinning boundaries were fitted to the data with quantile regression and stochastic frontier function (SFF) techniques with and without site index (SI) as a covariate. The models from both methods fitted the data well with either research plots or all plots. Slopes for size-density trajectories were -0.45 with the 0.99 quantile and -0.47 for SFF. Maximum stand density indices (SDI) were 1250 trees per hectare (TPH) with the 0.99 quantile and 1050-1060 TPH with SFF. Mortality occurred when site occupancy from SFF reached 0.75, suggesting a zone of imminent mortality. Curvilinear trends in maximum SDI across SI for both methods indicate that self-thinning varies with site quality. Any management regimes that increase site quality and productivity will increase the self-thinning boundary.Original Abstract: La loi de l'auto-eclaircie a ete beaucoup utilisee pour prevoir la dynamique des populations soumises a une competition intra et interspecifique. En foresterie, c'est un concept sylvicole important pour maintenir la sante des peuplements face aux changements climatiques et aux stress biotiques, mais des incertitudes subsistent parce que les limites traditionnelles de l'auto-eclaircie ont ete fixees subjectivement sans egard a la qualite de station. Nous avons traite cette problematique en analysant des donnees sur le pin ponderosa (Pinus ponderosa Lawson & C. Lawson) recoltees dans 109 placettes de recherche mesurees de facon repetee et 59 placettes d'inventaire mesurees une seule fois a travers la Californie. Les limites de l'auto-eclaircie ont ete ajustees aux donnees a l'aide de techniques de regression quantile et de fonction limite aleatoire (FLA) avec et sans l'ajout de l'indice de qualite de station (IQS) comme covariable. Les modeles obtenus avec chacune des deux methodes se sont bien ajustes aux donnees provenant uniquement des placettes de recherche ou de l'ensemble des placettes. La pente des trajectoires entre la taille des arbres et la densite des peuplements etait de -0,45 avec le quantile 0,99 et de -0,47 avec la FLA. La valeur maximale de l'indice de densite des peuplements (IDP) etait de 1250 arbres a l'hectare avec le quantile 0,99 et de 1050 a 1060 arbres a l'hectare avec la FLA. La mortalite des arbres debutait lorsque l'occupation de la station atteignait 0,75 selon la FLA, ce qui indique une zone de mortalite imminente. Une tendance curvilineaire entre l'IDP maximal et l'IQS dans le cas des deux methodes indique que l'auto-eclaircie varie selon la qualite de station. Tout regime d'amenagement qui augmente la qualite et la productivite de la station va produire une augmentation de la limite de l'auto-eclaircie.

Wildfires and prescribed burns may influence the intensity and severity of insect outbreaks by affecting the vigor of residual trees, altering aspects of stand structure and abundance of preferred hosts, and by changing the physical environment within forest stands. Prescribed burn timing and frequency are particularly important aspects of the fire regime to consider because they can alter numerous aspects of tree vigor, stand structure, and environmental conditions, and can be manipulated by managers. We evaluated ponderosa pine (Pinus ponderosa Douglas ex P. Lawson & C. Lawson) defoliation patterns in relation to season (fall and spring) and interval (5 or 15 years) of prescribed burn in the southern Blue Mountains of Oregon. Beginning in 2008 a pine butterfly (Neophasia menapia C. Felder & R. Felder) (Lepidoptera: Pieridae) outbreak coincided with a long-term experimental study, providing a unique opportunity to address this question. Defoliation patterns were measured in 2012. The 5 year interval plots had burned three times with five growing seasons of recovery and the 15 year interval plots had burned once with 15 growing seasons of recovery. Mean pine butterfly defoliation across the study area was about 71%. We found a significant interaction between season of burn and interval of burn on defoliation. Areas burned in the fall every 5 years had marginally less (about 5%) defoliation compared with areas that were burned in the fall 15 years previous. Regression tree analysis revealed that defoliation patterns varied based on stand location, percent mortality since the start of the experiment, and tree height. Our results show that (i) season of burn and interval of burn did not predispose these stands to increased defoliation during a pine butterfly outbreak and (ii) repeat burning may actually lead to lower defoliation. However, the effect we document is small and only marginally significant.Original Abstract: Les connaissances actuelles au sujet des interactions entre les perturbations de la foret, telles que le feu et la defoliation par les insectes, sont limitees. Les feux de foret et les brulages diriges peuvent influencer l'intensite et la severite des epidemies d'insecte. A cause de leur impact sur la vigueur des arbres residuels, ils peuvent modifier les aspects de la structure du peuplement et l'abondance des hotes preferes et changer l'environnement physique a l'interieur des peuplements forestiers. La frequence des brulages diriges et le moment ou ils sont effectues sont des aspects particulierement importants du regime des feux a prendre en compte parce qu'ils peuvent alterer plusieurs aspects de la vigueur des arbres, de la structure des peuplements et des conditions environnementales et peuvent etre manipules par les amenagistes. Nous avons evalue les schemas de defoliation du pin ponderosa (Pinus ponderosa Douglas ex P. Lawson & C. Lawson) en fonction de la saison (automne ou printemps) et de la periode de recurrence (5 ou 15 ans) des brulages diriges dans le sud des montagnes Bleues en Oregon. A partir de 2008, une epidemie de pieride du pin (Neophasia menapia C. Felder & R. Felder) (Lepidoptera : Pieridae) qui coincidait avec une etude experimentale a long terme a fourni une occasion unique de s'attaquer a cette question. Les schemas de defoliation ont ete mesures en 2012. Les placettes associees a l'intervalle de 5 ans avaient brule trois fois et recupere pendant cinq saisons de croissance et les placettes associees a l'intervalle de 15 ans avaient brule une fois et recupere pendant 15 saisons de croissance. Le taux moyen de defoliation par la pieride du pin dans l'ensemble de l'aire d'etude etait d'environ 71 %. Nous avons trouve une interaction significative entre la saison ou a eu lieu le brulage et l'intervalle entre les brulages dans le cas de la defoliation. Les zones brulees a l'automne a tous les 5 ans avaient subi legerement moins (environ 5 %) de defoliation que les zones brulees a l'automne 15 ans auparavant. L'analyse de l'arbre de regression a revele que les schemas de defoliation variaient selon l'endroit ou se trouvait un peuplement, le pourcentage de mortalite depuis le debut de l'experience et la hauteur des arbres. Nos resultats montrent que (i) la saison ou a eu lieu le brulage et l'intervalle de temps entre les brulages n'ont pas predispose ces peuplements a une defoliation plus severe lors d'une epidemie de pieride du pin et (ii) les brulages repetes peuvent en fait reduire la defoliation. Cependant, l'effet que nous avons note est faible et seulement legerement significatif.

The aims of the present study were to survey the experimental (axenic) and control (conventional) peanut plants for the predominant endophytic bacteria, and to characterize isolates with activity against selected A. flavus strains. Methods: Young axenic plants were grown from presumably bacteria-free embryos in the lab, and then they were grown in a field. Endophytic bacterial species were identified by the analysis of DNA sequences of their 16S-ribosomal RNA gene. DNA extracted from soil was also analyzed for predominant bacteria. Results: Mature seeds from the experimental and control plants contained several species of nonpathogenic endophytic bacteria. Among the eight bacterial species isolated from seeds, and DNA sequences detected in soil, Bacillus thuringiensis was dominant. All B. amyloliquefaciens isolates, the second abundant species in seeds demonstrated activity against A. flavus. This effect was not observed with any other bacterial isolates. There was no significant difference in number and relative occurrence of the two major bacterial species between the experimental and conventionally grown control seeds. Conclusion: Endophytic bacterial colonization derives from local soil and not from the seed source, and the peanut plant accommodates only selected species of bacteria from diverse soil populations. Some bacterial isolates showed antibiosis against A. flavus.

Out of twenty-six Lactobacillus strains with strong inhibition activity, twenty were identified as Lactobacillus plantarum and six as Lactobacillus fermentum . The most active eleven L. plantarum isolates were further characterized in vitro for some probiotic and safety properties. Only three isolates K10, K21, and ZS07 showed the ability to grow over 50% in the presence of 0.3% bile. Strong deconjugation efficiency was determined for CK06 and K21. The highest beta -galactosidase activity was shown in isolates ZS11, B01, CK06, and ZS07. Only three of the strains had the ability to produce tyramine: CK06, LM1, and ZS11. Strains K09, K21, ZS11, and ZS15 were susceptible to all tested antibiotics. Analysis of the results confirmed the L. plantarum isolates ZS07 and K21 as the most suitable for probiotic use, due to their desirable probiotic and safety characteristics.

New analytical approaches are providing an improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide testable hypotheses about the location of core habitats, corridors, and barriers to movement. The results indicate that connectivity is more sensitive to a species' dispersal ability than variation in landscape resistance to movement. Thus, it may prove difficult to optimize conservation strategies to maintain population connectivity for multiple species with disparate dispersal abilities and independent distributions.

Several Eucalyptus species exhibit characteristics that make them attractive in the bioenergy context. However, some of these also possess traits that suggest they could become invasive. To make a preliminary assessment of the risk of seedling establishment in the vicinity of Eucalyptus plantations, we conducted surveys at 3 sites in South Carolina and 16 sites in Florida. In South Carolina, no seedlings were detected in any sample transect. In Florida, we found seedlings within the boundaries of Eucalyptus plantations at 4 of the 16 sites surveyed. We also detected seedlings outside the boundaries of these same four plantations, but only two seedlings were detected at distances >45 m from plantation boundaries. All seedlings from Florida were either E. amplifolia , E. robusta , or E. grandis . The most predictive variable evaluated was latitude, with 27 degree N being the highest latitude at which seedlings established with regularity. Results of this survey indicate that, under current conditions, the spread of Eucalyptus spp. from plantations should be possible to manage with appropriate monitoring, but this should be evaluated further before Eucalyptus spp. are adopted for widespread planting.

During the initial 5.5 years, no stand manipulation or unusually high-mortality events occurred. Afterwards, three treatments were applied consisting of trees thinned and removed, trees felled and not removed, and artificial creation of snags produced by girdling and herbicide injection. The thinned treatments were designed to maintain the same live canopy density as the snag-created treatment, disregarding snags that remained standing. We monitored snag height, diameter, density, volume, and bark percentage; the number of cavities was monitored in natural snags only. During the first 5.5 years, recruitment and loss rates were stable, resulting in a stable snag population. Large snags ( greater than or equal to 25 cm diameter) were common, but subcanopy small snags (10 to <25 cm diameter) dominated numerically. Large natural snags survived (90% quantile) significantly longer (6.0-9.4 years) than smaller snags (4.4-6.9 years). Large artificial snags persisted the longest (11.8 years). Cavities in natural snags developed within 3 years following tree death. The mean number of cavities per snag was five times greater in large versus small snags and large snags were more likely to have multiple cavities, emphasizing the importance of mature pine stands for cavity-dependent wildlife species.Original Abstract: Une etude d'une duree de 14 ans portant sur les caracteristiques des chicots a ete etablie dans des peuplements de pin a encens (Pinus taeda L.) dans le sud-est des Etats-Unis. Durant les 5,5 premieres annees, il n'y a eu aucune intervention ni episode de mortalite inhabituellement elevee. Par la suite, trois traitements ont ete appliques : eclaircie avec enlevement des arbres abattus; abattage d'arbres laisses sur place; et creation artificielle de chicots par annelation et injection d'herbicide. Les eclaircies ont ete planifiees de maniere a conserver la meme densite de couvert forestier vivant que le traitement de creation de chicots en ne tenant pas compte des chicots qui sont demeures debout. Nous avons effectue un suivi de la hauteur, de la densite et du volume des chicots ainsi que du pourcentage d'ecorce sur les chicots; le nombre de cavites a ete releve sur les chicots naturels seulement. Pendant les 5,5 premieres annees, les taux de recrutement et de perte sont demeures stables, d'ou une population stable de chicots. Les gros chicots (diametre greater than or equal to 25 cm) etaient communs mais les petits chicots (diametre = 10 a < 25 cm) en sous-etage dominaient en nombre. Les gros chicots naturels ont survecu (quantile 90%) significativement plus longtemps (6,0-9,4 ans) que les chicots plus petits (4,4-6,9 ans). Les gros chicots artificiels ont persiste le plus longtemps (11,8 ans). Des cavites se sont formees dans les chicots naturels moins de trois ans apres la mort des arbres. Le nombre moyen de cavites par chicot etait cinq fois plus eleve sur les gros chicots que sur les petits et les gros chicots etait plus susceptibles d'avoir plus d'une cavite, faisant ressortir l'importance des pinedes matures pour les especes sauvages dont le sort est lie a la presence de cavites.

(West Carpathians, Slovakia), which is characterized by low thermal fluctuations throughout the year (6-10 degree C). We examined the life cycle and secondary production of three mayfly species (Baetis alpinus, Baetis rhodani and Rhithrogena semicolorata) and three stonefly species (Protonemura nitida, Protonemura hrabei and Nemurella pictetii). We found an unusually slow univoltine cycle for P. nitida and an asynchronous life cycle for B. alpinus, with first-stage nymphs occurring almost all year round. Uncommonly low abundances of B. rhodani were found, which indicates that the population lives at its ecological limit. Moreover, for the first time we acquired and analysed the data on secondary production of P. nitida, which reached the highest values (3335 mg DW m super(-2) y super(-1)) among all investigated species. In summary, the total annual secondary production of the mayfly community (889 mg DW m super(-2) y super(-1))was seven times lower than the annual secondary production of the stonefly community (6233 mg DW m super(-2) y super(-1)).

Salmonella enterica serovar Typhimurium is a prevalent cause of foodborne disease, and a considerable number of S. Typhimurium isolates from humans and livestock are resistant to three or more antibiotics. The majority of these MDR S. Typhimurium isolates are resistant to tetracycline, a commonly used and clinically and agriculturally relevant antibiotic. Because exposure of drug-resistant bacteria to antibiotics can affect cellular processes associated with virulence, such as invasion, we investigated the effect tetracycline had on the invasiveness of tetracycline-resistant MDR S. Typhimurium isolates. Results: The isolates selected and tested were from two common definitive phage types of S. Typhimurium, DT104 and DT193, and were resistant to tetracycline and at least three other antibiotics. Although Salmonella invasiveness is temporally regulated and normally occurs during late-log growth phase, tetracycline exposure induced the full invasive phenotype in a cell culture assay during early-log growth in several DT193 isolates. No changes in invasiveness due to tetracycline exposure occurred in the DT104 isolates during early-log growth or in any of the isolates during late-log growth. Real-time PCR was used to test expression of the virulence genes hilA, prgH, and invF, and these genes were significantly up-regulated during early-log growth in most isolates due to tetracycline exposure; however, increased virulence gene expression did not always correspond with increased invasion, and therefore was not an accurate indicator of elevated invasiveness. This is the first report to assess DT193 isolates, as well as the early-log growth phase, in response to tetracycline exposure, and it was the combination of both parameters that was necessary to observe the induced invasion phenotype. Conclusions: In this report, we demonstrate that the invasiveness of MDR S. Typhimurium can be modulated in the presence of tetracycline, and this effect is dependent on growth phase, antibiotic concentration, and strain background. Identifying the conditions necessary to establish an invasive phenotype is important to elucidate the underlying factors associated with increased virulence of MDR Salmonella.

The differences between lepidoptera taxocenoses in individual oak stands were analyzed. A total of 96 species and 2,140 individuals were found. Species abundance peaked in May, while number of species and species diversity reached the highest values from April to May and from April to June, respectively. Abundance showed two notable peaks in flush feeders and in late summer feeders. Lepidoptera taxocenosis in the study plot Horny haj (isolated forest, high density of ants) differed significantly from all other taxocenoses according to Sorensen's index of species similarity, species diversity, analysis of similarity on the basis of permutation and pairwise tests (ANOSIM), seasonal variability of species composition, and NMDS ordination.Original Abstract: Llevamos a cabo un analisis estructurado de las taxocenosis de larvas de lepidop-teros que viven en las copas del roble de dalechampii (Quercus dalechampii Ten.) en nueve parcelas del estudio en los Pequenos Carpatos (Europa central).

Very little is known about this non-timber commodity relative to timber, although significant volumes of ginseng root have been harvested from the same forests along with timber. The harvest of ginseng correlated positively and significantly with hardwood forest area, hardwood growing stock volume, and timber removals. Also, it correlated with hardwood growing stock on public forestlands in the region. The annual wholesale value of American ginseng was estimated at approximately $26.9 million compared to annual stumpage value of harvested hardwood timber of just over $1.27 billion. The volume of ginseng root harvested from natural forests represents substantial extraction of biomass, and the associated value represents substantial income for people living in an economically marginalized region. Co-management of eastern hardwood forests for timber and non-timber forest products could improve local economies and better conserve the biodiversity of these forests.

The intensity of both the similarity and divergence in voting decisions of inhabitants living in towns and cities on one hand, and in the countryside on the other, show varying rates of (in)stability, not only over time, but also in the spatial context, depending on the socio-economic, political, and historical predispositions of the country and its territorial units. The cardinal ambitions of this paper is both to evaluate the profile of urban-rural voter preferences of the main political parties on the Slovak political scene during the period of 1998-2010 at the national as well as at the regional level, and to reveal the socio-spatial mosaic in the electoral choices of people living in urban and rural environments in different parts of Slovakia using tools of cartographic interpretation.

The inflorescence branches of Triticeae cereals and grasses, including wheat, barley, and 400-500 wild species, are usually contracted into a spike formation, with the number of flowering branches (spikelets) per node conserved within species and genera. Perennial Triticeae grasses of genus Leymus are unusual in that the number of spikelets per node varies, inflorescences may have panicle branches, and vegetative stems may form subterranean rhizomes. Leymus cinereus and L. triticoides show discrete differences in inflorescence length, branching architecture, node number, and density; number of spikelets per node and florets per spikelet; culm length and width; and perimeter of rhizomatous spreading. Quantitative trait loci controlling these traits were detected in 2 pseudo-backcross populations derived from the interspecific hybrids using a linkage map with 360 expressed gene sequence markers from Leymus tiller and rhizome branch meristems. Alignments of genes, mutations, and quantitative trait loci controlling similar traits in other grass species were identified using the Brachypodium genome reference sequence. Evidence suggests that loci controlling inflorescence and stem branch architecture in Leymus are conserved among the grasses, are governed by natural selection, and can serve as possible gene targets for improving seed, forage, and grain production.

As part of a feasibility study to assess environmental and parenting influences on preschooler physical activity (PA) (Ninos Activos), the aim of this study was to identify what parents do to encourage or discourage PA among Hispanic 3-5 year old children to inform the development of a new PA parenting practice instrument and future interventions to increase PA among Hispanic youth. Methods: Nominal Group Technique (NGT), a structured multi-step group procedure, was used to elicit and prioritize responses from 10 groups of Hispanic parents regarding what parents do to encourage (5 groups) or discourage (5 groups) preschool aged children to be active. Five groups consisted of parents with low education (less than high school) and 5 with high education (high school or greater) distributed between the two NGT questions. Results: Ten NGT groups (n = 74, range 4-11/group) generated 20-46 and 42-69 responses/group for practices that encourage or discourage PA respectively. Eight to 18 responses/group were elected as the most likely to encourage or discourage PA. Parental engagement in child activities, modeling PA, and feeding the child well were identified as parenting practices that encourage child PA. Allowing TV and videogame use, psychological control, physical or emotional abuse, and lack of parental engagement emerged as parenting practices that discourage children from being active. There were few differences in the pattern of responses by education level. Conclusions: Parents identified ways they encourage and discourage 3-5 year-olds from PA, suggesting both are important targets for interventions. These will inform the development of a new PA parenting practice scale to be further evaluated. Further research should explore the role parents play in discouraging child PA, especially in using psychological control or submitting children to abuse, which were new findings in this study.

Online behavior change programs promoting healthy diet and physical activity are convenient and may be effective for reducing disparities related to obesity. This report presents the protocol guiding the design and evaluation of a culturally and developmental appropriate online obesity prevention program for young African American girls. Methods/Design: The Butterfly Girls and the Quest for Founder's Rock is an 8-episode online program delivered as an animated, interactive comic. The program promotes healthy diet and physical activity and is specifically designed for 8-10 year old African American girls. Girls, parents, and community representatives provided formative feedback on cultural relevance and developmental appropriateness. A three-group (treatment, comparison, wait-list control) randomized design (n = 390 parent/child dyads) is employed, with child as the unit of assignment. Change in body mass index is the primary outcome; change in fruit and vegetable consumption, water, and physical activity are secondary outcomes. Data collection occurs at baseline, approximately 3 months after baseline (i.e., completion of the online program), and approximately three months later (i.e., maintenance assessment). Two dietary recalls are collected at each data collection period by trained interviewers using the Nutrient Data System for Research (NDSR 2012) system. Physical activity is objectively measured by seven days of accelerometry. Psychosocial and process data are also collected. Girls in the treatment and comparison groups will be interviewed at post 1 to obtain information on personal reactions to the program.

The SRRC-1 formulation contains diammonium phosphate as the FR chemical along with urea and dimethyloldihydroxyethyleneurea. Because a trace amount of formaldehyde was still expected to be released from SRRC-1-treated FR cotton under high heat, it was preferable to eliminate the dimethyloldihydroxyethyleneurea, leading to the revised formulation SRRC-2. It has a higher content of diammonium phosphate and did not use the polyethylene emulsion that was in SRRC-1. Both formulations were of low cost as they were developed at SRRC using industrial grade chemicals. The fabrics were evaluated with a cone calorimeter using three heat flux levels, 20, 30, and 50kW/m super(2). On the basis of the overall cone calorimeter results for heat released and ignition times, FR NW fabrics that were treated with SRRC-2 were found to be slightly superior in flammability properties to those treated with the earlier SRRC-1 formulation, but the differences were statistically insignificant. Both preparations were much less flammable than the untreated control cotton NW fabrics. Compared with the untreated NW fabrics, the FR fabrics had higher visible smoke production.

These compounds may either directly scavenge reactive oxygen or nitrogen species or they may modulate the activity of signal transduction enzymes leading to changes in the expression of antioxidant genes. Alternatively, they may reduce plasma lipid levels by modulating lipid metabolic genes in tissues and thus reduce indirectly lipid-mediated oxidative and endoplasmic reticulum stress through their hypolipidemic effect. Here we review the proposed molecular mechanisms by which curcumin, a polyphenol present in the rhizomes of turmeric (Curcuma longa) spice, influences oxidative and lipid-mediated stress in the vascular system. At the molecular level, mounting experimental evidence suggests that curcumin may act chemically as scavenger of free radicals and/or influences signal transduction (e.g., Akt, AMPK) and modulates the activity of specific transcription factors (e.g., FOXO1/3a, NRF2, SREBP1/2, CREB, CREBH, PPAR[gamma], and LXR[alpha]) that regulate the expression of genes involved in free radicals scavenging (e.g., catalase, MnSOD, and heme oxygenase-1) and lipid homeostasis (e.g., aP2/FABP4, CD36, HMG-CoA reductase, and carnitine palmitoyltransferase-I (CPT-1)). At the cellular level, curcumin may induce a mild oxidative and lipid-metabolic stress leading to an adaptive cellular stress response by hormetic stimulation of these cellular antioxidant defense systems and lipid metabolic enzymes. The resulting lower oxidative and lipid-mediated stress may not only explain the beneficial effects of curcumin on inflammation, cardiovascular, and neurodegenerative disease, but may also contribute to the increase in maximum life-span observed in animal models.

Known as a bioactive polyphenolic extract of Turmeric, curcumin has a broad range of health benefit properties for humans. Recently, active research on curcumin with respect to aging and related traits in model organisms has demonstrated that curcumin and its metabolite, tetrahydrocurcumin (THC), increase mean lifespan of at least three model organisms: nematode roundworm, fruit fly Drosophila, and mouse. Nematodes grown on media containing curcumin showed a significantly increased lifespan by reducing the production of reactive oxygen species. Genes osr-1, sek-1, mek-1, skn-1, unc-43, sir-2.1, and age-1 are required for curcumin-mediated lifespan extension. The lifespan extension of Drosophila by curcumin supplementation was associated with increased superoxide dismutase (SOD) activity, and decreased lipofuscin and malondialdehyde levels. Curcumin up-regulated expression of SOD genes and down-regulated expression of several age-related genes, such as dInR, ATTD, Def, CecB, and DptB. In addition, THC extended lifespan in Drosophila and inhibited the oxidative stress response by regulating FOXO and Sir2. Mice fed diets containing THC starting at the age of 13 months had significantly increased mean lifespan. In summary, the positive effects of curcumin on lifespan extension likely arise from beneficial regulation of common oxidative stress responses and age-related genes. Understanding the molecular mechanism(s) of curcumin action has provided base knowledge and rationale for future human clinical trials, and for nutritional intervention in aging and age-associated disorders in humans.

Long term, imidacloprid suppressed but did not eliminate termite activity in treated trees. Noviflumuron bait did not significantly reduce the proportion of trees with high termite activity but significantly increased the number of trees with no termite activity. Noviflumuron changed termite distribution by possibly eliminating only some fraction of numerous colonies whereby surviving colonies avoided trees containing dead termites.

Experiments conducted with one to ten thousand termites from differing colonies infesting wood in buckets demonstrated that acoustical emission detector readings significantly increased when number of termites increased. Termites were also detected in infested trees with the installation of several wave guides into their trunks. These devices can detect termites and changes in termite activity caused by changes in termite numbers, making it an effective pest management professional and research tool for finding and evaluating termite infestations and efficacy of treatments in specific locations.

Mesocosms (1.25 0.6 0.8 m) were filled with sediment and planted with monocultures of one of three obligate wetland plant species, Typha latifolia, Thalia dealbata, and Sagittaria latifolia, or left nonvegetated to serve as controls. Mesocosms were amended with nitrate, ammonium, and phosphate over a 4-h hydraulic retention time, followed by an 8-h flushing with nonamended water to assess residual nutrient leaching in both summer and winter exposures. Significant interactions between vegetation type and season were noted for both nitrate and total inorganic phosphorus concentrations and loads. Future research will focus on altering hydraulic retention time for improved efficiency, as well as the specific contribution of microbial activity to nutrient mitigation.

We examined the effects of four forest regeneration treatments on residual snag density and compared those with densities found in unharvested, naturally regenerated forests (controls) during the second, fourth, and sixth year after timber harvest in mixed pine-hardwood forests of Arkansas and Oklahoma. Regeneration treatments were clearcut with snag creation, shelterwood, single-tree selection, and group selection. Density of large snags ( greater than or equal to 25.0 cm DBH) differed only during the sixth year after harvest, with shelterwoods having a lower density of large snags (1.0 snags/ha) than the control or group selection stands (4.0 and 4.2 snags/ha, respectively). Density of small snags (10.0-24.9 cm DBH) mirrored residual basal area, with controls and group-selection stands having the greatest snag densities. Creation of snags in clearcuts by injection with herbicides caused initial snag density in these areas to be greater than other treatments, but density in clearcuts declined sharply by 6 years after harvest. In the absence of snag creation, treatments such as shelterwoods that remove most trees may have snag densities below that required to address some management objectives without additional snag creation.Original Abstract: Les arbres morts sur pied (chicots) sont une composante importante des ecosystemes forestiers car ils servent de source de nourriture et de lieu de nidification et de repos pour de nombreux vertebres. Nous avons etudie les effets de quatre traitements de regeneration forestiere sur la densite residuelle de chicots et compare ces resultats a la densite de forets regenerees naturellement et non exploitees (temoins) au cours des deuxieme, quatrieme et sixieme annees apres la coupe de forets mixtes de pins et de feuillus de l'Arkansas et de l'Oklahoma. Les traitements de regeneration incluaient : une coupe a blanc avec creation de chicots, une coupe progressive d'ensemencement, une coupe de jardinage par pied d'arbre et une coupe de jardinage par groupe. La densite de gros chicots (diametre a hauteur de poitrine - DHP greater than or equal to 25,0 cm) a ete differente seulement pendant la sixieme annee apres la coupe au cours de laquelle les coupes progressives contenaient une plus faible densite de gros chicots (1,0 chicot/ha) que les temoins et les coupes de jardinage par groupe (respectivement 4,0 et 4,2 chicots/ha). La densite de petits chicots (DHP = 10,0-24,9 cm) etait proportionnelle a la surface terriere residuelle, c'est-a-dire que les plus fortes densites etaient associees aux temoins et aux coupes de jardinage par groupe. La creation de chicots dans les coupes a blanc par injection d'herbicides a initialement produit une plus grande densite de chicots que les autres traitements, mais elle avait fortement diminue 6 ans apres la coupe. Sans creation additionnelle de chicots, des traitements comme la coupe progressive, qui preleve la plupart des arbres, peuvent engendrer une densite de chicots sous le seuil vise par certains objectifs d'amenagement.

Childhood obesity is more prevalent among underserved minority children. The study measured the sleep duration of underserved minority children living in a large US urban environment using accelerometry and its relationship with BMI, socioeconomic status (SES), gender, ethnicity and physical activity. Methods: Time spent on sleep and physical activity among 333 Hispanic and 150 black children (9-12 y) was measured objectively by accelerometry over 5-7 consecutive days. The children were recruited at 14 underserved community centers in Houston, Texas, between January 2009 and February 2011. Body weight and height were measured in duplicate. Results: The majority of children (88.8%) wore the monitor for 6 consecutive days. The children slept 8.8 plus or minus 0.6 (mean plus or minus SD) h/d and spent 45 plus or minus 24 min/d on moderate-vigorous physical activity (MVPA). Hispanic children slept 0.2 h/d longer (P < 0.001) than black children. Obese children slept 0.2 h/d less (P < 0.02) than normal-weight children. SES had no effect on sleep duration. There was a significant interaction between gender and age (P < 0.03); girls aged 11-12 y slept 0.3 h/d less than boys and the younger girls. Children slept 0.6 h/d longer (P < 0.001) during the weekend than weekdays. No relation was detected between sleep duration and MVPA time. Conclusions: Minority children living in a large metropolitan area in the US are not meeting the National Sleep Foundation recommendation for sleep duration of 10-11 h/d. Longitudinal studies based on objective measures are needed to establish causality between sleep duration and obesity risk among minority children.

The Impact of Multiple Standards Regimes AN - 1417526720; 201333196 AB - Agri-food standards are often envisaged as a regulatory tool to create uniformity in production. However, as Dunn argues, 'standards... produce unique regulatory landscapes rather than the uniform ones standardizers envisage'. To account for this variation, scholars consider contextual factors such as market institutions, cultural norms, and the structural organization of agriculture. I argue that as standards increasingly overlap, intersect, and even contradict each other, they emerge as significant contextual features in their own right. This article analyses how producers for Russia's burgeoning fast-food industry respond to the competing demands of multiple agri-food standards. Drawing on interviews and site visits with Russian agricultural producers and food processors, I illustrate how the presence of multiple competing standards can both undermine expected standardizing effects and empower producers to adopt and incorporate standards in novel ways. I find that in their efforts to satisfy both multinational firms and domestic consumers, producers legitimize practices that may only comply partially with the various standards they claim to meet.

A 96-well plate micro-dilution broth bioassay developed for fungicide discovery was used to provide strawberry growers with a rapid assessment of the fungicide sensitivity of Botrytis isolates against 16 fungicides. Three sensitivity phenotypes were identified: benzimidazole and dicarboximide resistant, benzimidazole resistant and dicarboximide sensitive, and an intermediate response to both fungicides. Codon at position 198 in the [roman] beta [/roman]-tubulin gene confirmed benomyl resistance. This bioassay rapidly identifies fungicide resistance and allows growers to quickly adjust their disease management strategy.

A further aim was to measure the polyhydroxybutyrate production of select organisms on lignocellulosic-derived monosaccharides arabinose, xylose, glucose and mannose. Findings: We examined the sensitivity of seven polyhydroxyalkanoate producing bacteria: Azohydromonas lata, Bacillus megaterium, Bacillus cereus, Burkholderia cepacia, Pseudomonas olevorans, Pseudomonas pseudoflava and Ralstonia eutropha, against seven fermentation inhibitors produced by the saccharification of lignocellulose: acetic acid, levulinic acid, coumaric acid, ferulic acid, syringaldehyde, furfural, and hyroxymethyfurfural. There was significant variation in the sensitivity of these microbes to representative phenolics ranging from 0.25-1.5 g/L coumaric and ferulic acid and between 0.5-6.0 g/L syringaldehyde. Inhibition ranged from 0.37-4 g/L and 0.75-6 g/L with acetic acid and levulinic acid, respectively. B. cepacia and P. pseudoflava were selected for further analysis of polyhydroxyalkanoate production. Conclusions: We find significant differences in sensitivity to the fermentation inhibitors tested and find these variations to be over a relevant concentration range given the concentrations of inhibitors typically found in lignocellulosic hydrolysates. Of the seven bacteria tested, B. cepacia demonstrated the greatest inhibitor tolerance. Similarly, of two organisms examined for polyhydroxybutyrate production, B. cepacia was notably more efficient when fermenting pentose substrates.

A substantial amount of information has been reported on the genotypic variation and beneficial genetic manipulation of soybeans. For better understanding of the consequences of genetic manipulation, elucidation of soybean protein composition is necessary, because of its direct relationship to phenotype. We have conducted studies to determine the composition of storage, allergen and anti-nutritional proteins in cultivated soybean using a combined proteomics approach. Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) was implemented for the separation of proteins along with matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) and liquid chromatography mass spectrometry (LC-MS/MS) for the identification of proteins. Our analysis resulted in the identification of several proteins, and a web based database named soybean protein database (SoyProDB) was subsequently built to house and allow scientists to search the data. This database will be useful to scientists who wish to genetically alter soybean with higher quality storage proteins, and also helpful for consumers to get a greater understanding about proteins that compose soy products available in the market. The database is freely accessible.

With the completion of the International Space Station (ISS) and its designation as a national laboratory, ARS looks forward to conducting even more scientific studies, and more in-depth studies, in the unique environments provided by the ISS. ARS scientists and their collaborators will utilize the ISS to gather fundamental and working knowledge of importance to agriculture and biomedicine. ARS anticipates several research initiatives. The microgravity environment will provide opportunities for improved 3D in vitro models of the pig liver and bovine mammary gland. The ISS offers an important platform for testing instrument prototypes and algorithms for hyperspectral remote imaging and analysis of crop growth and well-being, forage land quality, irrigation practices, soil erosion, and farm-related pollution sources. Studies of germplasm (seeds, eggs, and sperm) storage and mutation on the ISS may offer new insights into the physiochemical mechanisms of successful long-term germplasm storage. Novel gene expression occurs in the microgravity environment, and new genetic mutations have been found after cosmic radiation of plant seeds. Thus, new epigenetic- or genetic-based phenotypes might be found that, for example, result in superior disease resistance in the crucially important cereal crops that feed the world. The USDA's six Human Nutrition Research Centers can take advantage of the ISS to study the impact of nutrients and "nutraceuticals" on bone remodeling and atrophy, muscle atrophy and regeneration, immune function, and the aging process, since the microgravity environment is known to affect these systems in a deleterious fashion. Furthermore, experiments in a microgravity environment will help dissect gravity's epigenetic effects on organ gene expression during mammalian development since it is difficult to isolate the pari passu influences of increasing mass and length that accompany growth on earth. Thus, the value-added outcome of this type of research could aide in understanding fetal and childhood development and in treating many debilitating diseases of the elderly, such as osteoporosis, sacropenia, cancer, and chronic infections, here on Earth. It can be anticipated that other important research initiatives, as yet unimagined, will occur to ARS scientists during the coming years of utilizing the ISS National Laboratory.

Unfortunately, most bacterial XIs that have been expressed in S. cerevisiae are either not functional, require additional strain modification, or have low affinity for D-xylose. This study analyzed several XIs from rumen and intestinal microorganisms to identify enzymes with improved properties for engineering S. cerevisiae for D-xylose fermentation. Results: Four XIs originating from rumen and intestinal bacteria were isolated and expressed in a S. cerevisiae CEN.PK2-1C parental strain primed for D-xylose metabolism by over expression of its native D-xylulokinase. Three of the XIs were functional in S. cerevisiae, based on the strain's ability to grow in D-xylose medium. The most promising strain, expressing the XI mined from Prevotella ruminicola TC2-24, was further adapted for aerobic and fermentative growth by serial transfers of D-xylose cultures under aerobic, and followed by microaerobic conditions. The evolved strain had a specific growth rate of 0.23 h super(-1) on D-xylose medium, which is comparable to the best reported results for analogous S. cerevisiae strains including those expressing the Piromyces sp. E2 XI. When used to ferment D-xylose, the adapted strain produced 13.6 g/L ethanol in 91 h with a metabolic yield of 83% of theoretical. From analysis of the P. ruminicola XI, it was determined the enzyme possessed a V sub( max ) of 0.81 [mu]mole/min/mg protein and a K sub( m ) of 34 mM. Conclusion: This study identifies a new xylose isomerase from the rumen bacterium Prevotella ruminicola TC2-24 that has one of the highest affinities and specific activities compared to other bacterial and fungal D-xylose isomerases expressed in yeast. When expressed in S. cerevisiae and used to ferment D-xylose, very high ethanol yield was obtained. This new XI should be a promising resource for constructing other D-xylose fermenting strains, including industrial yeast genetic backgrounds.

The genome of SBW25 has been sequenced, and among sequenced strains of pseudomonads, SBW25 appears to be most closely related to P. fluorescens WH6. In the authors' laboratories, WH6 was previously shown to produce and secrete 4-formylaminooxyvinylglycine (FVG), a non-proteinogenic amino acid with selective herbicidal and antimicrobial activity. Although SBW25 does not have the genetic capacity to produce FVG, we were interested in determining whether this pseudomonad might produce some other type of non-proteinogenic amino acid. Results: P. fluorescens SBW25 was found to produce and secrete a ninhydrin-reactive compound with selective antimicrobial properties. This compound was purified from SBW25 culture filtrate and identified as the non-proteinogenic amino acid L-furanomycin [2S,2'R,5'S)-2-amino-2-(5'methyl-2',5'-dihydrofuran-2'-yl)acetic acid]. Conclusions: The identification of furanomycin as a secondary metabolite of SBW25 is the first report of the production of furanomycin by a pseudomonad. This compound was known previously only as a natural product produced by a strain of Streptomyces. This report adds furanomycin to the small list of non-proteinogenic amino acids that have been identified as secondary products of pseudomonads. This study also extends the list of bacteria that are inhibited by furanomycin to include several plant pathogenic bacteria.

As the prevalence of M. bovis decreases in the United States, interference from other mycobacteria play an increasingly important role in preventing the eradication of M. bovis. To identify mycobacteria other than M. bovis that may be interfering with current diagnostic tests, a retrospective study was performed to identify mycobacteria isolated from clinical tissues at the National Veterinary Services Laboratories between 1 January 2004 and 9 October 2011. Results: During the study period, 2,366 mycobacteria other than M. bovis were isolated from samples submitted for clinical diagnosis of M. bovis. Fifty-five mycobacterial species were isolated during this time period. In cattle, M. avium complex, M. fortuitum/fortuitum complex, M. smegmatis, M. kansasii, and M. terrae complex were the predominate species other than M. bovis isolated from tissues submitted for culture. Mycobacteria other than M. bovis isolated from deer were predominantly M. avium complex, M. terrae/terrae complex, and M. fortuitum/fortuitum complex. Conclusions: These data provide information characterizing the species and relative prevalence of mycobacteria other than M. bovis that may interfere with current diagnostic tests.

Media selection is an important determination of culture sensitivity, and the planned discontinuation of the BACTEC 460 TB culture system has challenged veterinary diagnostic laboratories to evaluate alternatives. At the National Veterinary Services Laboratories the BACTEC MGIT 960 and 4 solid media formulations were compared with the BACTEC 460 TB system on 6,795 veterinary diagnostic specimens submitted for Mycobacterium bovis culture. Results: M. bovis was isolated from 2.6% of the samples and atypical mycobacteria from 4.4% of the samples. The BACTEC 12B media isolated significantly more M. bovis (93.1% of positive samples) than MGIT 960 media (81.9%). However, contamination rates were much higher for the MGIT media, 17-24%, compared to 7% for BACTEC, suggesting that contamination was a major cause of MGIT reduced sensitivity. Time to signal positive was 2.37 weeks (95% CI 2.24-2.5) for the MGIT, and 3.2 weeks (95% CI 3.07-3.3) for the BACTEC, both earlier than any solid media. Mycobactosel LJ failed to isolate M. bovis from primary culture. An in-house 7H11 media supplemented with calf sera, hemolyzed blood, malachite green and pyruvate recovered more M. bovis (80.6%) with the least amount of contamination of any other solid media evaluated. Conclusion: Decontamination methods may have to be optimized and or MGIT media may have to be altered to reduce contamination in veterinary samples. Despite these issues, the MGIT 960 system is still favored over the use of solid media due to decreased time to recovery and the potential for higher sensitivity.

We used empirical demographic analyses to identify factors to enhance population establishment and survival of Chloropyron molle subsp. molle (Orobancaceae), an annual hemiparasite, and to compare reintroduced with natural populations. Twelve years after outplanting, the reintroduced population persists but is in decline; impediments to success include the lack of adaptive management response to weed invasions and muted variance in hydrology. Transplantation of Lilaeopsis masonii (Apiaceae), a rhizomatous perennial herb, failed to meet success criteria for mitigation at local project scale, but dispersal and establishment of metapopulation patches indicated persistence at the landscape scale. This species has been found to be genetically indistinct from a widespread congener, and has few threats to persistence so long as suitable habitat is present. These two examples demonstrate the need for integrated conservation management strategies that prioritize habitat connectivity and maintain physical processes to support dispersal in response to sea level rise. For the hemiparasite, assisted colonization may sustain populations threatened by sea level rise, but only if a strong commitment to effective stewardship is realized.Original Abstract: Les auteurs presentent des etudes de cas supportant l'amenagement de deux especes de plantes rares des terres humides intertidales dans l'estuaire de San Francisco. Ils ont utilise des analyses demographiques empiriques pour identifier les facteurs susceptibles d'accroitre l'etablissement et la survie du Chloropyron molle subsp. molle (Orobranchaceae), une hemiparsite, et ils ont compare les populations naturelles et introduites. Douze ans apres la plantation, la population reintroduite persiste, mais decline; le blocage inclut le manque de reaction adaptative de l'amenagement a l'invasion par des herbes adventices et des modifications de variances de l'hydrologie. La transplantation du Lilaeopsis masonii (Apiaceae), une herbe perenne a rhizome, n'a pas satisfait les criteres de succes pour la mitigation a l'echelle locale du projet, mais la dispersion et l'etablissement de metapopulations en colonies indiquent sa persistance a l'echelle du paysage. On a constate que cette espece est genetiquement distincte d'une congenere largement etendue, et ne connait pas de menace a son existence, pourvu qu'il s'y trouve un habitat convenable.

A green fluorescent protein-expressing strain of A. flavus was used to measure fungal spread and aflatoxin levels in real-time following fungal infection of kernels. Among the four inbreds tested, MI82 showed the most resistance and Ga209 the least. TZAR101 was also resistant to fungal infection, whereas Va35 was susceptible to fungal infection. However, Va35 produced lower aflatoxin levels compared to the susceptible line Ga209. Fluorescence microscopy indicated that the site of entry of the fungus into the kernel was consistently through the pedicel. Entry through the pericarp was never observed in undamaged kernels. In view of these results, incorporation or overexpression of antifungal proteins should be targeted to the pedicel and basal endosperm region in developing kernels. Once the fungus has entered through the pedicel, it spreads quickly through the open spaces between the pericarp and the aleurone layer, ultimately colonising the endosperm and scutellum and, finally, the embryo. A clear correlation was established between fungal fluorescence and aflatoxin levels. This method provides a quick, reliable means of evaluating resistance to A. flavus in undamaged kernels and provides breeders with a rapid method to evaluate maize germplasm.

AN - 1352284889; 17938752 AB - Purposes: Use multidimensional polytomous item response modeling (MPIRM) to evaluate the psychometric properties of a television (TV) parenting practices (PP) instrument. Perform differential item functioning (DIF) analysis to test whether item parameter estimates differed across education, language, or age groups. Methods: Secondary analyses of data from three studies that included 358 children between the ages of 3 and 12 years old in Houston, Texas. TV PP included 15 items with three subscales: social co-viewing, instructive parental mediation, and restrictive parenting. The multidimensional partial credit model was used to assess the performance. DIF was used to investigate the differences in psychometric properties across subgroups. Results: Classical test theory analyses revealed acceptable internal consistency reliability (Cronbach's [alpha]: 0.72 to 0.83). More items displaying significant DIF were found across children's age groups than parental education or language groups. A Wright map revealed that items covered only a restricted range of the distribution, at the easier to respond end of the trait. Conclusions: TV PP scales functioned differently on the basis of parental education, parental language, and child age, with the highest DIF among the latter. Additional research is needed to modify the scales to minimize these moderating influences. Some items may be age specific.

AN - 1352284747; 17962243 AB - Childhood obesity has become an epidemic worldwide. In the past dozens of years, cases of childhood obesity have been increasing rapidly both in developed countries and developing countries. Obesity prevails worldwide and regionally. It brings about unprecedented heavy burden to children's health. It also plays a negative role in affecting children's mental health and academic performance. In the eyes of the fat children, the quality of their life is nearly the same as the children who receive cancer treatment. The article analyzes the reasons for childhood obesity with many examples of empirical study and recommends some measures for treating childhood obesity.

Their distribution in high-elevation montane regions of the state, areas in which fish and crayfish were absent historically, is largely unknown. We compiled occurrence records of River Otters in California from elevations >1100 m, and evaluated them using evidentiary standards. Based on 126 records, we report the widespread presence of River Otters in the Klamath, southern Cascades, and Sierra Nevada mountain ranges, including at elevations exceeding 3000 m. Sixty-three percent of the records met our definition as "verified", and the remaining 37% were considered "unverified". The distribution of observations through time and habitats in which observations were made were similar between verified and unverified records. River Otter records spanned the period from 1900 to 2010, with 50% occurring between 1991 and 2010. Ninety-three percent of the water bodies with records of River Otters contained nonnative prey (fish and crayfish). Those lacking nonnative prey all supported native prey, including amphibians and reptiles. Based on records that contained River Otter foraging observations, nonnative fishes and crayfish were represented in 89% of the total accounts, and native frogs and invertebrates were represented in 22%. It remains unclear whether River Otters occurred in California's high-elevation water bodies prior to the introduction of fish and crayfish, and additional research is needed to understand the possible influence of nonnative prey in allowing River Otters to expand their distribution in these habitats.

The Forest Vegetation Simulator (FVS) is used widely for forest management in the US, and its scope and complexity continue to increase. This paper focuses on the accuracy of estimates made by the Fire and Fuels Extension (FFE-FVS) predictions through comparisons between model outputs and measured post-fire conditions for the Cold Springs wildfire and on the sensitivity of model outputs to weather, disease, and fuel inputs. For each set of projected, pre-fire stand conditions, a fire was simulated that approximated the actual conditions of the Cold Springs wildfire as recorded by local portable weather stations. We also simulated a fire using model default values. From the simulated post-fire conditions, values of tree mortality and fuel loads were obtained for comparison to post-fire, observed values. We designed eight scenarios to evaluate how model output changed with varying input values for three parameter sets of interest: fire weather, disease, and fuels. All of the tested model outputs displayed some sensitivity to alternative model inputs. Our results indicate that tree mortality and fuels were most sensitive to whether actual or default weather was used and least sensitive to whether or not disease data were included as model inputs. The performance of FFE-FVS for estimating total surface fuels was better for the scenarios using actual weather data than for the scenarios using default weather data. It was rare that the model could predict fine fuels or litter. Our results suggest that using site-specific information over model default values could significantly improve the accuracy of simulated values.

In a designed experiment, harvest prescriptions with snag retention levels ranging from 0% to 100% in 15 experimental units were installed. Observations of standing snags and surface fuels were made 2, 4, 6, and 8years after the fire. Fire-killed snags fell rapidly over time, leading to elevated surface fuel levels in areas where no salvage logging was done. The 1000h and larger surface fuels were strongly related with basal area retention level, with values ranging from 0-60Mgha-1 by year eight. However, when expressed as a percent of standing retained biomass, surface fuel accumulation was not related to treatment. In year 8, surface fuel was 81% of retained bole biomass. The retention of snags after this wildfire event provided snags for wildlife foraging and nesting habitat, however most of these snags were lost within 8years after the fire. White fir snags were more stable than pine and appeared to be used with greater frequency than pine for cavity excavation.

To aid managers and researchers address this disease, an updated and accessible review of cave hibernacula and cave microclimates is presented. To maximize energy savings and reduce evaporative water loss during winter, most temperate vespertilionid bats in North America select caves with temperatures between 2 and 10 degree C, with 60%-100% relative humidity. Generally, the temperature in caves is similar to the mean annual surface temperature (MAST) of a region, which varies by latitude, altitude, and topography. However, MAST for most areas where caves are found in eastern North America is well above 10 degree C. Thus, various factors cause cold-air infiltration that reduces temperatures of these caves during winter. These factors include depth of cave, topographic setting, airflow patterns, cave configuration, and water infiltration. Factors affecting humidity, condensation, and evaporation are also addressed. In areas where MAST is above or below the thermal requirements of Geomyces destructans, many caves used by bats as hibernacula may still provide favorable sites for optimal growth of this fungus.Original Abstract: L'agent pathogene fongique Geomyces destructans que casues nez blanc syndrome, se developpe dans les conditions froides et humides trouvees dans les grottes ou hibernent les chauves-souris. Pour aider les gestionnaires et chercheurs a adresser cette maladie, une revue, mise a jour et accessible, des hibernacles et des microclimats des grottes est presentee. Afin de maximiser les economies d'energie et reduire les pertes d'eau par evaporation pendant l'hiver, la plus part des chauves-souris vespertilionides occupants les climats temperes de l'Amerique du Nord selectionne des grottes avec des temperatures entre 2 et 10 degree C, avec une humidite relative d'environ 60 % - 100 %. Generalement, la temperature dans les grottes est semblable a la moyenne annuelle de la temperature de surface (MATS) d'une region, qui varie selon la latitude, l'altitude et la topographie. Toutefois, la MATS pour la plupart des regions ou les grottes se trouvent dans l'Est de l'Amerique du Nord est bien superieure a 10 degree C. Ainsi, divers facteurs entrainent des infiltrations d'air froid qui reduisent la temperature des grottes pendant l'hiver. Ces facteurs comprennent: la profondeur de la grotte, le contexte topographique, les patrons de circulation d'air, la configuration de la grotte, et l'infiltration d'eau. Les facteurs affectant l'humidite, la condensation et l'evaporation sont egalement abordes. Dans les zones ou la MATS est au-dessus ou en dessous des exigences thermiques de Geomyces destructans, de nombreuses grottes utilisees par les chauves-souris comme hibernacles peuvent fournir des sites favorables pour une croissance optimale de ce champignon.

Switchgrass (Panicum virgatum L.), a native perennial herbaceous grass, is a promising candidate for cellulosic feedstock production. In this study, current and future (from 2080 to 2090) productivity is estimated across the central and eastern United States using ALMANAC, a mechanistic model that simulates plant growth over time. The ALMANAC model was parameterized for representative ecotypes of switchgrass. Our results indicate substantial variation in switchgrass productivity both within regions and over time. States along the Gulf Coast, southern Atlantic Coast, and in the East North Central Midwest have the highest current biomass potential. However, these areas also contain critical wetland habitat necessary for the maintenance of biodiversity and agricultural lands necessary for food production. The southern United States is predicted to have the largest decrease in future biomass production. The Great Plains are expected to experience large increases in productivity by 2080-2090 due to climate change. In general, regions where future temperature and precipitation are predicted to increase are also where larger future biomass production is expected. In contrast, regions that show a future decrease in precipitation are associated with smaller future biomass production. Switchgrass appears to be a promising biofuel crop for the central and eastern United States, with local biomass predicted to be high (> 10 Mg/ha) for similar to 50% of the area studied for each climate scenario. In order to minimize land conversion and loss of biodiversity, areas that currently have and maintain high productivity under climate change should be targeted for their long-term growth potential.

To understand its impact on the performance of genotypes in the Canal Point (CP) breeding program, the genotype-environment (GxE) interaction was appraised via additive main effects and multiplicative interactions (AMMI) analysis and group-based trajectory modeling (GTM). Forty-five selections of the CP01, CP02, and CP03 series and three cultivars were examined in replicated field tests at Hague and Canal Point, Florida, in the plant-cane (CP01-CP02 in 2006-07) or through the first ratoon (CP03 in 2007-09). Profile analyses of Brix, pol, and sucrose content (SC) were developed from stalks sampled at different times of year to follow their deterioration. Hague experienced more intense freeze nights (17-22 d yr super(-1) with temperatures [T sub(C)] from -0.4 degree C to -8 degree C) than CP (2 nights, rarely down to -2 degree C). Temperatures greater than or equal to -2 degree C increased SC in a majority of the genotypes and T sub(C) less than or equal to -4 degree C hastened juice deterioration. The response was nonlinear when T sub(C) gradually declined from 0 degree to -4 degree C, but linear after early freeze of less than or equal to -4 degree C. The AMMI analysis was appropriate for interpreting the GxE interaction variation, indicating a greater contribution from environments (location-year-sampling combinations) than from G or GxE interaction. The AMMI and GTM identified two to four reaction norms as differential performance under freeze: a susceptible group in the minority with SC declining constantly with T sub(C); the other groups typifying the common profile had an increase in SC with T sub(C) greater than or equal to -2 degree C and a decline with T sub(C) less than or equal to -4 degree C. Genotypes with the highest SC at the onset of freeze tended to hold this level longer than those with the lowest content. The identification of different reaction norms suggests that a genetic component may underpin freeze adaptation in modern sugarcane cultivars relative to the old tropical hybrids. However, breeding efforts to increase the tolerance of sugarcane cultivars to temperatures <-3 degree C must be given due consideration.

In response, the USFS and NPS initiated the North Cascadia Adaptation Partnership (NCAP) in 2010. The goals of the NCAP were to build an inclusive partnership, increase climate change awareness, assess vulnerability, and develop science-based adaptation strategies to reduce these vulnerabilities. The NCAP expanded previous science-management partnerships on federal lands to a larger, more ecologically and geographically complex region and extended the approach to a broader range of stakeholders. The NCAP focused on two national forests and two national parks in the North Cascades Range, Washington (USA), a total land area of 2.4 million ha, making it the largest science-management partnership of its kind. The NCAP assessed climate change vulnerability for four resource sectors (hydrology and access; vegetation and ecological disturbance; wildlife; and fish) and developed adaptation options for each sector. The NCAP process has proven to be a successful approach for implementing climate change adaptation across a region and can be emulated by other land management agencies in North America and beyond.

DO - http://dx.doi.org/10.3390/su5010136 ER - TY - JOUR T1 - Imputing forest carbon stock estimates from inventory plots to a nationally continuous coverage AN - 1315616913; 17659321 AB - The U.S. has been providing national-scale estimates of forest carbon (C) stocks and stock change to meet United Nations Framework Convention on Climate Change (UNFCCC) reporting requirements for years. Although these currently are provided as national estimates by pool and year to meet greenhouse gas monitoring requirements, there is growing need to disaggregate these estimates to finer scales to enable strategic forest management and monitoring activities focused on various ecosystem services such as C storage enhancement. Through application of a nearest-neighbor imputation approach, spatially extant estimates of forest C density were developed for the conterminous U.S. using the U.S.'s annual forest inventory. Results suggest that an existing forest inventory plot imputation approach can be readily modified to provide raster maps of C density across a range of pools (e.g., live tree to soil organic carbon) and spatial scales (e.g., sub-county to biome). Comparisons among imputed maps indicate strong regional differences across C pools. The C density of pools closely related to detrital input (e.g., dead wood) is often highest in forests suffering from recent mortality events such as those in the northern Rocky Mountains (e.g., beetle infestations). In contrast, live tree carbon density is often highest on the highest quality forest sites such as those found in the Pacific Northwest. Validation results suggest strong agreement between the estimates produced from the forest inventory plots and those from the imputed maps, particularly when the C pool is closely associated with the imputation model (e.g., aboveground live biomass and live tree basal area), with weaker agreement for detrital pools (e.g., standing dead trees). Forest inventory imputed plot maps provide an efficient and flexible approach to monitoring diverse C pools at national (e.g., UNFCCC) and regional scales (e.g., Reducing Emissions from Deforestation and Forest Degradation projects) while allowing timely incorporation of empirical data (e.g., annual forest inventory).

On the basis of the 16S rRNA, RNA polymerase alpha -subunit (rpoA) and 60 kDa chaperonin (cpn60) gene sequence analyses, it was shown that all the isolates were enterococci but formed two separate lines of descent. Pairwise 16S rRNA gene sequence comparisons demonstrated that the two novel organisms were most closely related to each other (97.9 %) and to Enterococcus aquimarinus (97.8 %). Both organisms contained major amounts of C sub(16:0), C sub(16:1) omega 7c, C sub(16:1) omega 7c, and C sub(18:1) omega 7c/12t/9t as the major cellular fatty acids. Based on biochemical, chemotaxonomic and phylogenetic evidence, the names Enterococcus lemanii sp. nov. (type strain PC32 super(T) = CCUG 61260 super(T) = NRRL B-59661 super(T)) and Enterococcus eurekensis sp. nov. (type strain PC4B super(T) = CCUG 61259 super(T) = NRRL B-59662 super(T)) are proposed for these hitherto undescribed species.

At a concentration of 30 mu M, captan, thiram, cyprodinil, chlorothalonil, azoxystrobin, and kelthane provided nearly 100% inhibition of the growth of all 10 Colletotrichum isolates. Iprodione, vinclozolin, metalaxyl, and fosetyl-Al did not inhibit growth of any isolate. Benomyl and thiobendazole inhibited growth of the C. fragariae and C. gloeosporioides isolates, but did not inhibit growth of the six C. acutatum isolates.This article not subject to US copyright law.

X. fragariae causes angular leaf spot in strawberry and is transmitted to production fields almost exclusively through infected nursery stock. Of the methods that we have investigated over the past several years, a modified heat treatment has proven to be very effective at reducing systemic infections in propagation material, but cultivar selection affected the outcome. Surface-sterilizing treatments also had an effect on angular leaf spot. We tried procedures from dipping plants in a solution of 10% chlorine bleach to the use of UV-C radiation to reduce the severity of angular leaf spots in the field. Lastly, a sanitation-type treatment, namely removing or trimming remnant leaf and petiole tissue from nursery-trimmed plants, was found to have a significant impact on angular leaf spot. No one method completely eliminated X. fragariae from the planting stock, but there is good indication that a strategic combination of control practices that includes heat treatment should help to reduce significantly the initial amount of bacteria introduced into a field.

The most troublesome species of cyanobacteria is Nostoc spongiaeforme. It is very difficult to control using currently accepted methods, i.e., aerial applications of copper sulfate. A non-copper algicide, the mono (N,N-dimethylalkylamine) salt of endothall has been suggested as an alternative method for controlling nuisance cyanobacterial and algal growths in California rice fields. The purpose of the experiments described here was to evaluate the effect of the mono (N,N-dimethylalkylamine) salt of endothall on growth of N. spongiaeforme and the green alga, Hydrodictyon reticulatum. In laboratory experiments, the mono (N,N-dimethylalkylamine) salt of endothall reduced N. spongiaeforme growth at 0.3 mg L super(-1). This effect was removed when rice straw was added to the growth medium, indicating that the rice straw may have introduced bacteria capable of degrading the mono (N,N-dimethylalkylamine) salt of endothall. In outdoor experiments, which used rice field water containing decomposing rice straw, the mono (N,N-dimethylalkylamine) salt of endothall concentrations between 0 and 5 mg L super(-1) had little effect on N. spongiaeforme. In contrast, H. reticulatum exhibited injury symptoms at 1 mg L super(-1) or greater. However, H. reticulatum recovered by the end of the 7-day exposure. It is not clear how this algicide will be useful in the management of N. spongiaeforme or H. reticulatum in California rice fields.

We compared the performance of different trap designs in a flight tunnel and in a vineyard by using a 7-component synthetic kairomone blend, with a focus on trap visual cues. In flight tunnel experiments, a clear delta trap performed better than other traps. When we tested clear delta, green delta, or clear wing traps baited with a cut grape shoot, >50% of female grape berry moths made complete upwind flights. However, the clear delta trap was the only design that resulted in female moths entering the trap. Similar results were observed when females were tested with different traps (clear delta, green delta, white delta, clear wing, or green wing traps) baited with the kairomone lure. Adding a visual pattern that mimicked grape shoots to the outside surface of the clear delta trap resulted in 66% of the females that made upwind flights entering the trap. However, the positive effect of adding a visual pattern to the trap was not observed in a vineyard setting, where clear delta traps with or without a visual pattern caught similar numbers of females. Still, the number of male and female grape berry moths captured in clear delta traps with or without a visual pattern was not significantly different from the number of male and female grape berry moths captured in panel traps, suggesting that the use of these delta traps could be a less cumbersome alternative to oil-coated panel traps for monitoring female grape berry moth.

We examine differences in N uptake and several morphological variables that influence uptake at temperatures between 5 and 25 degree C. We contrast two native perennial grasses in western North America: Elymus elymoides and Pseudoroegneria spicata; two invasive annual grasses: Bromus tectorum and Taeniatherum caput-medusae; and one highly selected non-native perennial grass: Agropyron cristatum. The influence of temperature on N uptake is poorly characterized, yet these invasive annual grasses are known to germinate in warm soils in the autumn, and both experience cool soils during the short growing season following snowmelt in the spring. To further explore the influence of temperature on the correlation between morphological variables and N uptake, our data are applied to a previously published path model and one proposed here. Differences in N uptake between native and invasive grasses were small at the lowest temperature, but were large at the highest temperature. At lower temperatures, uptake of N by annuals and perennials was correlated with leaf N and mass. At higher temperatures, uptake by annuals was correlated only with these leaf traits, but uptake by perennials was correlated with these leaf traits as well as root N and mass. Consequently, our results imply that annual grasses face fewer morphological constraints on N uptake than perennial grasses, and annual grasses may gain further advantage in warmer temperature conditions or during more frequent warm periods.

Inferences on migration routes can be made from tracking genetic types in populations found in specific habitats and testing how they are linked to other types. Water samples were taken over a 4-year period from waterways in the Upper Oconee River Watershed, Georgia, to recover isolates of thermophilic Campylobacter. The isolates were typed by multilocus sequence typing (MLST) and analyzed to determine the overall diversity of Campylobacter in that environment. Forty-seven independent isolates were recovered from 560 samples (8.4 %). Two (4 %) isolates were Campylobacter coli, three (6 %) isolates were putatively identified as Campylobacter lari, and the remaining 42 (90 %) were Campylobacter jejuni. The C. jejuni and C. coli isolates were typed by the Oxford MLST scheme. Thirty sequence types (STs) were identified including 13 STs that were not found before in the MLST database, including 24 novel alleles. Of the 17 previously described STs, 10 have been isolated from humans, 6 from environmental water, and 6 from wild birds (five types from multiple sources). Seven sites had multiple positive samples, and on two occasions, the same ST was isolated at the same site. The most common type was STST61 with four isolates, and the most common clonal complex was CC179 with nine isolates. CC179 has been commonly associated with environmental water. Although some Campylobacter STs that were found in the Oconee River engage in widespread migration, most are tightly associated with or unique to environmental water sources.

We combined data from weather stations and forest inventory plots (FIA) across the upper Great Lakes region (USA) to study the relationship between measures of drought stress and mortality for four drought sensitivity species groups using a weight-of-evidence approach. For all groups, the model that predicted mortality as a function of mean drought length had the greatest plausibility. Model tests confirmed that the models for all groups except the most drought tolerant had predictive value. We assumed that no relationship exists between drought and mortality for the drought-tolerant group. We used these empirical models to develop a drought extension for the forest landscape disturbance and succession model LANDIS-II, and applied the model in Oconto county, Wisconsin (USA) to assess the influence of drought on forest dynamics relative to other factors such as stand-replacing disturbance and site characteristics. The simulations showed that drought stress does affect species composition and total biomass, but effects on age classes, spatial pattern, and productivity were insignificant. We conclude that (for the upper Midwest) (1) a drought-induced tree mortality signal can be detected using FIA data, (2) tree species respond primarily to the length of drought events rather than their severity, (3) the differences in drought tolerance of tree species can be quantified, (4) future increases in drought can potentially change forest composition, and (5) drought is a potentially important factor to include in forest dynamics simulations because it affects forest composition and carbon storage.

Here, we report the cloning and characterization of the MAT locus from 10 California isolates that cause atypical blotch symptoms on barley. Analysis of the full-length nucleotide sequences of one MAT1-1 (1,993 bp) and nine MAT1-2 (2,149 or 2,161 bp) idiomorphs revealed high (98-99 %) similarity to those of Ptt isolates. However, distinct SNP patterns were identified in the newly cloned MAT idiomorphs. Two new MAT1-2-specific SNPs were found to be conserved in one Australia and eight California isolates that all cause similar atypical blotch symptoms. Phylogenetic analysis indicated that all 10 California isolates form a separate branch (or clade) within the Ptt group, except for one that appears to be ancestral to both Ptt and Ptm. PCR primers designed based on the identified SNP patterns were used successfully to differentiate each atypical isolate from highly virulent forms. This study extends our previous work and, taken together, the results demonstrate that the genetic variation at the MAT locus correlates with variation in the form-specific disease phenotype, and that MAT-specific SNPs can serve as reliable and convenient markers for subspecies level differentiation in P. teres, an economically important plant-pathogenic ascomycete (http://en.wikipedia.org/wiki/Single_nucleotide_polymorphism).

Strains NRRL Y-2311-1, NRRL 50382, NRRL 50383, and NRRL 50384, representing diverse isolation sources and phylogenetic clades, produced PMA from alkaline H sub(2)O sub(2)-pretreated corn fiber and wheat straw as sole carbon sources. Pretreated wheat straw was better than pretreated corn fiber, and strain NRRL 50383 gave the highest overall yields of PMA. The addition of CaCO sub(3) plus supplementary hydrolytic enzymes enhanced PMA production. Four basal media were compared for PMA production, and the best was found to be a N-limited pullulan production medium (PM). In this medium, PMA production took place during growth limitation. Under optimal conditions, strain NRRL 50383 produced more than 20 g PMA/l from 5 % (w/v) pretreated wheat straw in PM with 3 % (w/v) CaCO sub(3) and supplementary enzymes.

Dedicated to the memory of Nancy E. Beckage AN - 1291611193; 17639111 AB - One of the more unusual groups of insect pathogens consists of members of the family Polydnaviridae, insect DNA viruses that live in mutual symbioses with their associated parasitoid wasp (Hymentoptera) carriers until they are injected into specific lepidopteran hosts. Once inside this secondary host, polydnaviruses cause a wide variety of negative effects that ultimately ensure the survival of the parasitoid larvae. Because of their unusual life strategy and genetic features, it had been difficult to fully characterise polydnaviruses in terms of evolutionary history, replication cycle and functions in the host that might normally be well characterised for more conventional viruses. Recently, our understanding of polydnavirus evolutionary origins, gene content, genome organisation and functions in parasitism has greatly increased. Key findings are summarised in this review with emphasis on evolution of polydnavirus genes and genomes, their functional roles in insect pathology and their potential applications in insect biological control and biotechnology.

There has been an issue whether this formulation could possibly have negative effects on soil microbial diversity by altering microbial binding to soil particles or to one another and thus restricting their mobility and role in carbon and nutrient cycling. We conducted an 8-year study annually applying ultra-high rates of PAM to soil and then monitored impacts on soil bacterial diversity. In July and August, we measured active soil bacterial and fungal biomass and microbial diversity in soils receiving 0 (control), 2,691, and 5,382 kg active ingredient PAMha super(-1). Active microbial biomass in soil was 19-33 % greater in the untreated control than soil treated with 2,691 or 5,382 kg of active ingredient PAMha super(-1). Active bacterial biomass in soil was 21-31 % greater in the control treatment than in soil treated with 2,691 or 5,382 kg of active ingredient PAMha super(-1) in August, but not July. Active fungal biomass in soils was 38-50 % greater in the control treatment than soil treated with 2,691 or 5,382 kg of active ingredient PAMha super(-1) in July, but not August. Molecular methods were used to access the bacterial diversity, richness, and evenness in an agricultural soil that received 0 (control), 2,691, and 5,382 kg of active ingredient PAMha super(-1). We found that although soil receiving these massive PAM application rates and prolonged exposure may reduce active bacterial and fungal biomass, PAM application did not substantially or consistently affect bacterial structural diversity, richness, or evenness in this agricultural soil.

AN - 1287887620; 23148238 AB - Totipotent embryonic stem cell lines have not been established from ungulates; however, we have developed a somatic stem cell line from the in vitro culture of pig epiblast cells. The cell line, ARS-PICM-19, was isolated via colony cloning and was found to spontaneously differentiate into hepatic parenchymal epithelial cell types, namely hepatocytes and bile duct cells. Hepatocytes form as monolayers and bile duct cells as 3-dimensional bile ductules. Transmission electron microscopy revealed that the ductules were composed of radially arranged, monociliated cells with their cilia projecting into the lumen of the ductule whereas hepatocytes were arranged in monolayers with lateral canalicular structures containing numerous microvilli and connected by tight junctions and desmosomes. Extensive Golgi and rough endoplasmic reticulum networks were also present, indicative of active protein synthesis. Analysis of conditioned medium by 2-dimensional electrophoresis and mass spectrometry indicated a spectrum of serum-protein secretion by the hepatocytes. The PICM-19 cell line maintains a range of inducible cytochrome P450 activities and, most notably, is the only nontransformed cell line that synthesizes urea in response to ammonia challenge. The PICM-19 cell line has been used for several biomedical- and agricultural-related purposes, such as the in vitro replication of hepatitis E virus, a zoonotic virus of pigs, and a spaceflight experiment to evaluate somatic stem cell differentiation and liver cell function in microgravity. The cell line was also evaluated as a platform for toxicity testing and has been used in a commercial artificial liver rescue device bioreactor. A PICM-19 subclone, PICM-19H, which only differentiates into hepatocytes, was isolated and methods are currently under development to grow PICM-19 cells without feeder cells. Feeder-cell-independent growth will facilitate the study of mesenchymal-parenchymal interactions that influence the divergent differentiation of the PICM-19 cells, enhance our ability to genetically modify the cells, and provide a better model system to investigate porcine hepatic metabolism.

Previous house fly surveys have detected the pathogen Staphylococcus aureus Rosenbach 1884, which causes cutaneous and septic infections in mammals, and enterotoxic food poisoning. We assessed the fate of GFP-expressing S. aureus (GFP-S. aureus) in the house fly alimentary canal with microscopy and by culture of whole flies and excreta. Furthermore, the concurrent expression of the antimicrobial peptide gene defensin was measured in the crop, proventriculus, midgut, and fat body. As soon as 4 h postingestion (PI), GFP-S. aureus were visualized as cocci or diplococci in the hindgut and rectum of flies fed approximately 105 colony forming units. Bacteria persisted up to 6 h PI but significantly decreased. Excretion of viable GFP-S. aureus peaked at 2 h PI and, although significantly less, continued up to 4 h PI. defensin was highly upregulated locally in the alimentary canal and systemically in fat body at 2, 4, and 6 h PI making this study the first to report, to our knowledge, an epithelial and systemic response to a bacterium with lysine-type peptidoglycan in flies exposed via feeding. While flies harbored S. aureus for up to 6 h PI, the highest probability of vectoring biologically relevant amounts of bacteria occurred 0-2 h PI. The combined effects of excretion, digestion and antimicrobial effectors likely contribute to loss of ingested bacteria. Nonetheless, house flies are relevant vectors for S. aureus up to 2 h PI and environmental reservoirs up to 6 h PI.

The three known causal agents of HLB are species of alpha -proteobacteria: 'Candidatus Liberibacter asiaticus'. 'Ca. L. africanus', and 'Ca. L. americanus'. Previous studies have found distinct variations in temperature sensitivity and tolerance among these species. Here, we describe the use of controlled heat treatments to cure HLB caused by 'Ca. L. asiaticus', the most prevalent and heat-tolerant species. Using temperature-controlled growth chambers, we evaluated the time duration and temperature required to suppress or eliminate the 'Ca. L. asiaticus' bacterium in citrus, using various temperature treatments for time periods ranging from 2 days to 4 months. Results of quantitative polymerase chain reaction (qPCR) after treatment illustrate significant decreases in the 'Ca. L. asiaticus' bacterial titer, combined with healthy vigorous growth by all surviving trees. Repeated qPCR testing confirmed that previously infected, heat-treated plants showed no detectable levels of 'Ca. L. asiaticus', while untreated control plants remained highly infected. Continuous thermal exposure to 40 to 42 degree C for a minimum of 48 h was sufficient to significantly reduce titer or eliminate 'Ca. L. asiaticus' bacteria entirely in HLB-affected citrus seedlings. This method may be useful for the control of 'Ca. Liberibacter'-infected plants in nursery and greenhouse settings.

Temperatures that grasshopper eggs are exposed to during rangeland fires are mediated by species-specific oviposition traits. This experiment examined egg mortality in two slant-faced grasshopper species with differing oviposition traits, namely Aulocara elliotti (Thomas) and Opeia obscura (Thomas). We hypothesized that A. elliotti egg mortality would increase with fire intensity because the shallow egg location below the soil surface would result in exposure to higher temperatures, and that the deeper O. obscura eggs would not be affected by fire intensity. Fire intensity did not significantly affect the mortality of O. obscura eggs, with very low mortality in all treatments. Fire intensity significantly affected mortality of A. elliotti eggs, which are laid in shallow egg pods with the midpoint of the egg clutch at a depth of similar to 0.825 cm. Aulocara elliotti egg mortality increased with higher levels of heat application, with 79% egg mortality in the 4500 kg.ha-1 heat treatment. Heat effects on A. elliotti egg mortality were similar to those previously observed for another shallow-egg-laying species. Limited research has examined if rangeland fires reduce population densities of specific economically important grasshopper species. The results from this experiment indicate that grasshopper species with the midpoint of the egg pod less than 1 cm below the surface are likely in general to be vulnerable to fire-induced egg mortality during rangeland fires.

Although many pathways of nitrogen input and loss from rangelands have been carefully quantified, cattle-mediated N losses are often poorly understood. We used measurements of cattle N consumption rate, weight gains, and spatial distribution in shortgrass rangeland of northeastern Colorado to evaluate the influence of cattle on rangeland N balance. Specifically, we estimated annual rates of N loss via cattle weight gains and spatial redistribution of N into pasture corners and areas near water tanks, and used previous studies to calculate ammonia volatilization from urine patches. Using measurements of plant biomass and N content inside and outside grazing cages over 13 yr, we estimate that cattle stocked at 0.65 animal unit months (AUM).ha-1 consumed 3.34 kg N.ha-1.yr-1. Using an independent animal-based method, we estimate that cattle consumed 3.58 kg N.ha-1.yr-1 for the same stocking rate and years. A global positioning system tracking study revealed that cattle spent an average of 27% of their time in pasture corners or adjacent to water tanks, even though these areas represented only 2.5% of pasture area. Based on these measurements, we estimate that cattle stocked at 0.65 AUM.ha-1 during the summer can remove 0.60 kg N.ha-1 in cattle biomass gain and spatially redistribute 0.73 kg N.ha-1 to areas near corners and water tanks. An additional 0.17 kg N.ha-1 can be lost as NH3 volatilization from urine patches. Cumulatively, these cattle-mediated pathways (1.50 kg N.ha-1) may explain the imbalance between current estimates of atmospheric inputs and trace gas losses. While NOx emission remains the largest pathway of N loss, spatial N redistribution by cattle and N removed in cattle biomass are the second and third largest losses, respectively. Management of cattle-mediated N fluxes should be recognized as one means to influence long-term sustainability of semiarid rangelands.

Investigations on soils along this riparian system revealed two distinct geomorphic surfaces, the modern swamp floodplain (classified as Inceptisols according to Soil Taxonomy) and slightly elevated landforms (intra-swamp terraces) with more developed soils (Alfisols and Ultisols). This study examined soil characteristics and sediment provenance on the Black River floodplain and its tributaries in the Atlantic Coastal Plain of South Carolina to determine the properties and pedogenic relationship between these two geomorphic surfaces and to propose a theory for the geomorphic evolution for soils on these landforms. Spatial characterization of the soils will benefit ecologists researching the biological aspects of blackwater ecosystems such as the concentration and flux of dissolved organic carbon (DOC). Results showed terrace soils had aquic moisture regimes while floodplain soils had peraquic moisture regimes. Floodplain surface horizons were organic carbon-rich (5% to 25% OC) but seldom with enough to qualify as organic soil material. Discontinuities occurred within the soils of both landforms indicating two distinct sedimentological environments. The fine-earth fraction of soil profiles on both landforms generally had upper strata composed mainly of silt and clay indicative of wash load sediments underlain with sandy strata indicative of bed load deposits. Fine clay distribution and fine clay:total clay ratios (FC/TC) showed argillic horizon development in the terrace subsoils but not in the floodplain soils. Micromorphology supported argillic horizons for the terraces, but also revealed modest clay accumulation in pores and channels of the floodplain soils. These floodplain clay features are interpreted to have formed during a period of subaerial weathering. The sandy strata were likely deposited during the beginning of the transgressions following the down cutting that occurred during the regressions and sea level lows. Silt fraction comparisons between the blackwater soils and soils on other landscapes in the region suggest the silts and clays likely were deposited in an estuarine environment late in the transgressions.

AN - 1273605391; 23149419 AB - Locoism is a toxic syndrome of livestock caused by the ingestion of a subset of legumes belonging to the Astragalus and Oxytropis genera known as "locoweeds". Locoweeds contain the toxic indolizidine alkaloid swainsonine, which is produced by the endophytic fungi Undifilum species. Previously we reported that swainsonine concentrations differ between populations of Oxytropis sericea. We hypothesized that the genotype of the plant, endophyte, or an interaction of the two may be responsible for the differences in swainsonine concentration between populations of O. sericea. To test this hypothesis, plants derived from seeds collected at each location were grown in a common garden, Undifilum oxytropis isolates from each location were cultured and grown in a common environment, and a plant genotype by endophyte cross inoculation was performed. Here we show that the genotype of the endophyte is responsible for the differences in swainsonine concentrations observed in the two populations of O. sericea. Published by Elsevier Ltd.

AN - 1273597788; 23125119 AB - The genetic basis of the biosynthesis of the germination-arrest factor (GAF) produced by Pseudomonas fluorescens WH6, and previously identified as 4-formylaminooxyvinylglycine, has been investigated here. In addition to inhibiting the germination of a wide range of grassy weeds, GAF exhibits a selective antimicrobial activity against the bacterial plant pathogen Erwinia amylovora. We utilized the in vitro response of E. amylovora to GAF as a rapid screen for loss-of-function GAF phenotypes generated by transposon mutagenesis. A Tn5 mutant library consisting of 6364 WH6 transformants was screened in this Erwinia assay, resulting in the identification of 18 non-redundant transposon insertion sites that led to loss of GAF production in WH6, as confirmed by TLC analysis. These insertions mapped to five different genes and four intergenic regions. Three of these genes, including two putative regulatory genes (gntR and iopB homologues), were clustered in a 13 kb chromosomal region containing 13 putative ORFs. A GAF mutation identified previously as affecting an aminotransferase also maps to this region. We suggest that three of the genes in this region (a carbamoyltransferase, an aminotransferase and a formyltransferase) encode the enzymes necessary to synthesize dihydroGAF, the putative immediate precursor of GAF in a proposed GAF biosynthetic pathway. RT-qPCR analyses demonstrated that mutations in the gntR and iopB regulatory genes, as well as in a prtR homologue identified earlier as controlling GAF formation, suppressed transcription of at least two of the putative GAF biosynthetic genes (encoding the aminotransferase and formyltransferase) located in this 13 kb region.

AN - 1273455925; 23086230 AB - Coniine is an optically active toxic piperidine alkaloid and nicotinic acetylcholine receptor (nAChR) agonist found in poison hemlock (Conium maculatum L.). Coniine teratogenicity is hypothesized to be attributable to the binding, activation, and prolonged desensitization of fetal muscle-type nAChR, which results in the complete inhibition of fetal movement. However, pharmacological evidence of coniine actions at fetal muscle-type nAChR is lacking. The present study compared (-)-coniine, (+)-coniine, and nicotine for the ability to inhibit fetal movement in a day 40 pregnant goat model and in TE-671 cells that express fetal muscle-type nAChR. Furthermore, α-conotoxins (CTx) EI and GI were used to antagonize the actions of (+)- and (-)-coniine in TE-671 cells. (-)-Coniine was more effective at eliciting electrical changes in TE-671 cells and inhibiting fetal movement than was (+)-coniine, suggesting stereoselectivity by the receptor. The pyridine alkaloid nicotine did not inhibit fetal movement in a day 40 pregnant goat model, suggesting agonist specificity for the inhibition of fetal movement. Low concentrations of both CTxs potentiated the TE-671 cell response and higher concentrations of CTx EI, and GI antagonized the actions of both coniine enantiomers demonstrating concentration-dependent coagonism and selective antagonism.

AN - 1273205876; 22773308 AB - Baits containing brodifacoum rodenticide were aerially applied to eradicate invasive black rats from Palmyra Atoll, an important biodiversity center. Bait application must be sufficient to be effective, while minimizing environmental hazards by not exceeding designated label rates, prompting our bait density assessments for two aerial drops. With few physical or human resources on this remote, uninhabited atoll, assessments were particularly challenging, requiring observations within 30 min of aerial application to avoid bait loss to rats, crabs, or elements. We estimated bait density using quadrat sampling within 13 terrestrial sampling areas. We also sampled 10 tidal flat areas to assess inadvertent bait scatter into marine aquatic environments. Of particular value for challenging sampling circumstances, our quadrats had to be lightweight and durable, which we addressed by using widely available PVC hoops ("Hula Hoops"), the size of which was ideal for sampling purposes. At 77.5 and 78.7 kg/ha, overall bait densities were very near to the target densities of 80 and 75 kg/ha, respectively. However, considerable variability in bait densities existed among sampled areas, 8.6-178.2 and 31.4-129.5 kg/ha for the respective drops, respectively. Environmental, human, and equipment factors likely accounted for this variability. Tidal flat sampling revealed variable bait scatter into aquatic environments, from 0-46.3 kg/ha across the two drops. No differences were found in average bait densities among 1-, 4-, and 7-m distances from high tide lines. Our methods might broadly assist bait density (and other) surveys under challenging circumstances.

This study builds on the estimates of potential supply in the Billion Ton Supply study prepared by the U.S. Department of Agriculture and the U.S. Department of Energy. Forest biomass sources include logging residue, thinnings, other removals, unused mill residue, urban wood waste, and conventionally sourced wood (pulpwood size material). To make the estimates, we assume that lower cost forest biomass will be supplied from integrated harvesting operations that also remove sawlogs and pulpwood. We also assume that such removals can be estimated at the county level in two ways: first, as a portion of recent estimates of logging residues; and second, by simulated thinning operations that use tops, branches, and small trees for biomass. Supply from thinning dense forest stands is assumed to occur over 30 yr. Harvest and stumpage costs are estimated for each of these methods. Final supply estimates for each county assume supply that is half-way between the two estimates. Forest and agricultural biomass supply estimates have been used to indicate that for a cost of $44 per oven dry ton (odt) at forest roadside or farm gate, we could produce produce 20-billion gal of advanced biofuels as called for under the 2007 Energy Independence and Security Act. Forests could provide about 40-million odt to produce 4-billion gal, and agricultural feedstocks could provide about 200-million odt and produce 16-billion gal of biofuel.

Isolates of A. hydrophila and F. columnare obtained from fish that died during farm outbreaks were subjected to in vitro evaluation of florfenicol (FFC), copper sulphate (CuSO4) and potassium permanganate (KMnO4). Florfenicol inhibited the growth of A. hydrophila and F. columnare more than CuSO4 and KMnO4. The minimum inhibition concentration (MIC) of FFC was 0.04 plus or minus 0 and 0.2 plus or minus 0.1 mg L-1 for A. hydrophila and F. columnare respectively, while the 50% inhibition concentration (IC50) for A. hydrophila and F. columnare was 0.23 plus or minus 0.01 and 0.4 plus or minus 0.2 mg L-1 respectively. Copper sulphate was more effective against A. hydrophila than KMnO4; CuSO4 had a MIC of 83.2 plus or minus 0 mg L-1 compared to 158.0 plus or minus 0 mg L-1 for KMnO4. Copper sulphate was also more effective against F. columnare than KMnO4. The IC50 values of CuSO4 and KMnO4 towards F. columnare were 4.8 plus or minus 0.3 and 8.7 plus or minus 1.6 mg L-1 respectively, and the minimum bactericidal concentration values of CuSO4 and KMnO4 towards F. columnare were 25.0 plus or minus 0 and > 158.0 mg L-1 respectively. In addition, F. columnare was more sensitive to CuSO4 and KMnO4 than A. hydrophila.

The disease was recently found in Central America and is threatening the multi-billion U.S. citrus industry. Many strains of X. fastidiosa are pathogens or endophytes in various plants growing in the U.S., and some strains cross infect several host plants. In this study, a TaqMan-based assay targeting the 16S rDNA signature region was developed for the identification of X. fastidiosa at the species level. Another TaqMan-based assay was developed for the specific identification of the CVC strains. Both new assays have been systematically validated in comparison with the primer/probe sets from four previously published assays on one platform and under similar PCR conditions, and shown to be superior. The species specific assay detected all X. fastidiosa strains and did not amplify any other citrus pathogen or endophyte tested. The CVC-specific assay detected all CVC strains but did not amplify any non-CVC X. fastidiosa nor any other citrus pathogen or endophyte evaluated. Both sets were multiplexed with a reliable internal control assay targeting host plant DNA, and their diagnostic specificity and sensitivity remained unchanged. This internal control provides quality assurance for DNA extraction, performance of PCR reagents, platforms and operators. The limit of detection for both assays was equivalent to 2 to 10 cells of X. fastidiosa per reaction for field citrus samples. Petioles and midribs of symptomatic leaves of sweet orange harbored the highest populations of X. fastidiosa, providing the best materials for detection of the pathogen. These new species specific assay will be invaluable for molecular identification of X. fastidiosa at the species level, and the CVC specific assay will be very powerful for the specific identification of X. fastidiosa strains that cause citrus variegated chlorosis.

Utilization of host resistance is the most economical and environmentally sound strategy in managing sheath blight (ShB). Ten ShB quantitative trait loci (QTLs) were previously mapped in a Lemont x Jasmine 85 recombinant inbred line (LJRIL) population using greenhouse inoculation methods at an early vegetative stage. However, confirmation of ShB-resistant QTLs under field conditions is critical for their utilization in marker-assisted selection (MAS) for improving ShB resistance in new cultivars. In the present study, we evaluated ShB resistance using 216 LJRILs under field conditions in Arkansas, Texas, and Louisiana during 2008 and 2009. We confirmed the presence of the major ShB-QTL qShB9-2 based on the field data and also identified one new ShB-QTL between markers RM221 and RM112 on chromosome 2 across all three locations. Based on the field verification of ShB evaluations, the microchamber and mist-chamber assays were simple, effective, and reliable methods to identify major ShB-QTLs like qShB9-2 in the greenhouse at early vegetative stages. The markers RM215 and RM245 were found to be closely linked to qShB9-2 in greenhouse and field assays, indicating that they will be useful for improving ShB resistance in rice breeding programs using MAS.

To investigate resistance to this complex in 26 commercial sugar beet cultivars, field studies and greenhouse studies with mature roots from the field were conducted with Rhizoctonia solani anastomosis group 2-2 IIIB strains and Leuconostoc mesenteroides. Based on means for the 26 cultivars in the 2010 and 2011 field studies, fungal rot ranged from 0 to 8%, bacterial rot ranged from 0 to 37%, total internal rot ranged from 0 to 44%, and surface rot ranged from 0 to 52%. All four rot variables resulted in significant (P < 0.0001) cultivar differences. Based on regressiona analysis, strong positive relationships (r super(2) from 0.6628 to 0.9320; P < 0.0001) were present among the rot variables. When ranking cultivars, the most consistent rot variable was surface rot, because 12 of 13 variable-year combinations had significant (P < 0.05) correlations. When cultivar ranking in greenhouse assays was compared, there was frequently a positive correlation with storage data but no relationship with field results. Thus, the greenhouse assays will identify storage rot resistance but field screening will be required to find resistance to this rot complex in the field.

Of the three isolates characterized, isolates UKR 44189 and UKR 44191 were confirmed to be isolates of PPV strain W, and UKR 44188 was confirmed to be an isolate of PPV strain D. UKR 44189 and UKR 44191 are very closely related to the PPV strain W isolate LV-145bt (HQ670748) from Latvia. Nucleotide and amino acid sequence identities between these three isolates were greater than 99%. This indicates that the isolates are very closely related and likely originated from a common source. The high genetic diversity among PPV-W strain isolates allowed the identification of potential recombination events between PPV isolates. It appears also that GF 305 peach and Prunus tomentosa are not hosts for the PPV isolate UKR 44189.

Modoc, grown in southeast Idaho, were observed with internal necrotic arcs and lines. Samples were obtained from potatoes that had been washed and packaged. No external symptoms were evident. Multiple samples were collected from the packing line and cut to check for internal defects as part of the normal grading procedure. The incidence of symptomatic tubers from these samples was determined by personnel at the packaging facility to be approximately 3%. Initially, one symptomatic and one asymptomatic tuber were tested. Total RNA extracted from these tubers were tested by RT-PCR at Aberdeen, Idaho, with primers specific for Potato mop top virus (PMTV) (1) and Tobacco rattle virus (TRV) (4). RT-PCR results showed that the symptomatic tuber produced a band at 416 bp with the PMTV primers, which was also present in the PMTV-positive control. No amplification was observed with the TRV primers. The asymptomatic tuber was negative for both PMTV and TRV. Subsequently, total RNA from four additional symptomatic tubers from the same lot were tested at USDA-ARS in Prosser, WA, by RT-PCR for TRV (4) and with a different set primers for PMTV (2). The tests included two PMTV-positive controls from cv. Alturas tubers (1), a healthy cv. Russet Burbank control, and a water control. Results showed that amplified products of 460 bp were obtained with the PMTV primers for the four symptomatic tubers and the same tubers were negative for TRV. In addition, symptomatic tissue from the four tubers tested positive for PMTV by ELISA using a commercially available kit (Adgen, Ayr, Scotland). Symptomless Russet Burbank tubers and water controls were negative in RT-PCR and ELISA tests. The 460 bp PMTV amplicon from two symptomatic Modoc tubers were cloned and sequenced. The sequences were identical and the sequence (GenBank Accession No. JX239990) was 100% identical to the corresponding sequences of PMTV isolates from North Dakota (HM776172) and Finland (AM503632). There was one nucleotide difference from the corresponding sequence of a PMTV isolate from Washington (JN132117). To our knowledge, this is the first published report of PMTV in Idaho and confirms that PMTV exists in southeast Idaho. A previous report made by Canada in 2004 (Plant Dis. 88:363) indicates that PMTV was found in multiple states and provinces, but no specific locations were identified. This report follows reports of PMTV in commercial potatoes in Washington (1), North Dakota (2), and Maine (3). In 2011, 129,000 hectares of potatoes were grown in Idaho, representing 29% of the fall grown potatoes in the United States. PMTV can cause quality problems and as evidenced by these samples with no external symptoms, problems may be compounded because of internal symptoms that may go undetected. The confirmation of PMTV alerts growers and processors to the presence of this virus in this important potato-producing state.

The first symptoms noted were downward curling of the terminal leaves accompanied by a rough puckered darker green texture. This was followed in time by greater distortion of the leaves with pale green on leaf margins. Older leaves with symptoms developed necrosis, with necrotic spots and streaks appearing on a few fruits. On some of these affected fruits, stems, peduncles, pedicels, and sepals also showed symptoms. Infected plants were badly stunted, and fruits in the upper parts of plants displaying severe symptoms remained very small. In just a few months, the disease spread to other tomato plants inside the greenhouse. A survey in May 2012 showed a disease incidence of 18% (156 symptomatic plants out of a total of 864) in this greenhouse. Initial screenings for possible viruses using ELISA (Agdia, Elkhart, IN), as well as a reverse transcription (RT)-PCR panel of 15 common tomato viruses in our laboratory were negative. Because of the symptoms and negative results for viruses, a viroid infection was suspected. Total plant RNA was prepared using TRIzol reagent (Invitrogen, Carlsbad, CA) from leaf tissues of eight diseased plants and one seed sample. Using real-time RT-PCR developed against Potato spindle tuber viroid (PSTVd) and some related pospiviroids (1), positive signals were observed with a mean Ct = 13.24 for leaf tissues and Ct = 19.91 for the seed sample. To obtain a full viroid genome, RT-PCR using two different sets of primers, one specific for PSTVd (PSTVd-F and PSTVd-R) (2). and a universal primer set for pospiviroids (MTTVd-F and MTTVd-R) (3) was performed. RT-PCR generated amplicons with expected size of similar to 360 bp from all eight leaf and one seed samples, but not from a healthy control. PCR products were cloned using the TOPO TA cloning kit (Invitrogen. Carlsbad, CA). A total of 22 full genomic sequences were obtained. A multi-sequence alignment generated a consensus sequence of 360 nt. designated as NC12-01 (GenBank Accession No. JX280944). BLASTn search in the NCBI database revealed the highest sequence identity of 96.9% to Australian (AY962324) and UK (AJ583449) isolates of PSTVd and 95.9% identity to the tomato isolate of PSTVd-CA1 (HM753555). Similar disease symptoms were observed on two 'Rutgers' tomato plants 2 weeks post mechanical inoculation and the presence of PSTVd was confirmed by real-time RT-PCR (1). A mock-inoculated plant did not show any symptoms. In the U.S.. natural infection of PSTVd on tomato was first identified in California in 2010 (3). To our knowledge, this is the first report of a natural occurrence of PSTVd on tomato in the eastern U.S. The diseased plants were contained, properly disposed of, and eradicated in this location. The broader geographic distribution of PSTVd on tomato in the U.S., and the potential latent infection in potato and a number of ornamentals (4), emphasizes the need for better plant and seed health tests for viroids on these plants.

Collard and kale (Brassica oleracea Acephala group), mustard green (B. juncea), and turnip green (B. rapa) are the most commonly planted members of the brassica leafy greens group. In the last 10 years, numerous occurrences of bacterial blight on these leafy vegetables have been reported in several states. One of the pathogens responsible for this blight is designated Pseudomonas cannabina pv. alisalensis. Two B. rapa (G30710 and G30499) and two B. juncea (PI418956 and G30988) plant introductions (PIs) that exhibited moderate to high levels of resistance to this pathogen in greenhouse studies were tested for field resistance in comparison with eight commercial cultivar representatives of turnip green, mustard green, collard, and kale. The two B. juncea PIs and one of the B. rapa PIs (G30499) were found to have significantly less disease than all tested cultivars except 'Southern Curled Giant' mustard green (B. juncea) and 'Blue Knight' kale (B. oleracea). Inheritance of resistance studies performed with populations derived from the resistant G30988 and two susceptible PIs provided some evidence that resistance may be controlled by a single recessive gene.

Mangosteen has the potential to occupy a rapidly expanding niche market in Hawaii. In October 2009, a disease was observed that produced brown leaf spots and blotches surrounded by bright yellow halos at a mangosteen orchard located in Hakalau, Hawaii (19 degree 53' 49" N, 155 degree 7' 35" W). Recently transplanted 10+ year old trees were 95 to 100% infected. Pieces of infected leaves and stems were surface-sterilized, plated on potato dextrose agar (PDA), and incubated at 24 degree C + 1 degree c for 21 days. The fungus growing on PDA was pale buff with sparse aerial mycelium and acervuli containing black, slimy spore masses. Single spore isolates were used for the morphological characteristics and molecular analysis. Conidia were 5-celled. Apical and basal cells were hyaline; the three median cells were umber to olivaceous. Conidia (n = 50) were 24.3 plus or minus 0.2 x 7.5 plus or minus 0.1 mu m, with apical appendages, typically three, averaging 24.3 plus or minus 0.4 mu m long, and a basal appendage averaging 6.7 plus or minus 0.2 mu m long. DNA sequences were obtained from the beta -tubulin gene and the internal transcribed spacer (ITS1 and ITS2) and 5.8S regions of the rDNA to confirm the identification. The morphological descriptions and measurements were similar to P. virgatula (Kleb.) Steyaert (1). Although sequence data of the ITS region (GenBank Accession No. JN542546) supports the identity of the fungus as P. virgatula, the taxonomy of this genus remains confused since there are only a few type cultures, so it is impossible to use sequences in GenBank to reliably clarify species names (2). To confirm pathogenicity, six leaves of two 3-year-old seedlings were inoculated. Seven-day-old cultures grown on 10% V8 agar at 24 degree C under continuous fluorescent lighting were used for inoculations. The inoculum consisted of spore suspensions in sterile distilled water adjusted to 6 x 10 super(5) conidia/ml. Using a fine haired paint brush, the inoculum was brushed onto the youngest leaves, while sterile distilled water was used as the control. The plants were incubated in a clear plastic bag placed on the laboratory bench at 24 degree C for 48 hours, then placed on a greenhouse bench and observed weekly for symptoms. After 14 days, leaf spots ranging in size from pinpoint to 5.4 mm in diameter with a distinctive yellow halo were present. Within 35 days, the leaf spots enlarged to leaf blotches ranging in size from 11.5 x 13.3 mm up to 28.3 x 34.6 mm with brown centers and a distinctive yellow halo identical to the field symptoms. A Pestalotiopsis sp. identical to that used to inoculate the seedlings was recovered from the leaf spots and blotches, confirming Koch's postulates. The experiment was repeated twice. Pestalotiopsis leaf blight has been reported in other countries growing mangosteen. including Thailand. Malaysia, and North Queensland, Australia (3). However, to our knowledge, this is the first report of a Pestalotiopsis sp. causing a disease on mangosteen in Hawaii. Although this disease is considered a minor problem in the literature (3). effective management practices should be established to avoid potential production losses.

It has been identified as a target for biological control in many parts of the world, including the United States. Several potted JKW plants in an outdoor study at the Oregon Department of Agriculture, Salem (44.93 degree N, 122.99 degree W) developed leaf spots. Samples collected on August 20, 2007, were sent to the FDWSRU for identification of the disease. The necrotic leaf spots were brown and large, 1 to 3 cm in diameter, and in some cases occupying 30% of the leaf area. Both hemispherical and discoid conidiomata with gloeoid spore masses (3) developed in necrotic areas of all leaves placed in moist chambers. Discoid conidiomata had dark, pedicellate bases subtending a fimbriate disc on which pale brown to brown gloeoid conidial masses were produced. Hemispherical conidiomata were black, circular, sessile, and somewhat flattened, within which similar, gloeoid conidial masses were produced. Conidia from each type of conidioma were unicellular, cylindrical to fusiform, hyaline, and 4.5 to 7.2 x 0.9 to 1.8 mu m (mean 5.7 x 1.33). Artificial inoculation of 15 plants was made on two occasions with a suspension of 10 super(6) conidia per ml, followed by two 16-hr dew periods at 25 degree C that were separated by an 8-hr "day; " a similar set of 15 non-inoculated plants served as controls each time. Symptoms similar to those in the original sample developed within 2 months after inoculation. The fungus was easily reisolated, and conidia from each type of conidioma produced similar growth on artificial media and similar disease after inoculation. The characteristics of conidial size and distinctly different conidiomata are diagnostic of Pilidium concavum (Desm.) Hoehn (3,4). A sequence of the ITS1-5.8S-ITS2 region DNA. extracted using a DNeasy Plant Mini Kit (QIAGEN). was found identical to that of P. concavum from Rosa sp. (BPI 1107275: GenBank Accession No. AY487094). using BLAST. This isolate. FDWSRU 07-116. has been deposited in the US National Fungus Collection (BPI 883546) and at the Centraalbureau voor Schimmelcultures (CBS 1327251. Sequence data have been deposited in GenBank (JQ790789). To our knowledge, this is the first report of P. concavum causing disease on a member of the Polygonaceae in North America (1). a disease clearly different from a Japanese Mycosphaerella sp. under consideration for biological control of JKW in the United Kingdom (2).

The disease occurs in two forms, namely a net form net blotch (NFNB) caused by P. teres f. teres and a spot form net blotch (SFNB) caused by P. teres f. maculata. As in other parts of the northern Great Plains, in the Mon-Dak area (western North Dakota and eastern Montana), NFNB is prevalent. SFNB was first reported in western Montana in 1983 (1) and more recently in eastern North Dakota in 2010 (3) but not in the Mon-Dak area. In the summer of 2011, unusual spot lesions that were surrounded by necrosis or chlorosis were observed on different barley cultivars in fields at Williston, ND, Nesson Valley, ND, and Sidney, MT areas. Diseased leaves from various barley cvs. from the three locations were transferred to water agar and incubated at room temperature for 24 h to induce sporulation. Morphological examination of conidia (45 to 169 x 15 to 21 mu m) did not show significant differences from a known isolate of P. teres f. teres 0-1 (provided by Tim Friesen, ARS, Fargo, ND). For pathogenicity testing, six 14-day-old plants of barley cv. Tradition were sprayed until runoff with a 2,000 spore/ml suspension of two isolates from each location and the control P. teres f. maculata isolate DEN2.6 (provided by Tim Friesen). Plants were incubated first in a lighted humidity chamber for 24 h and then in a greenhouse for 7 days at 21 degree C. Regardless of inoculum source, spot lesions surrounded by necrosis or chlorosis, typical of SFNB, appeared on the inoculated leaves within 7 days. Fungi isolated from symptomatic leaves were identified as P. teres and the morphology of the conidia was undistin-guishable from those of P. teres f. teres. All control plants which were sprayed with sterile distilled water were symptomless. The pathogenicity test was repeated. Rapid PCR detection and amplicon sequencing (2) of the internal transcribed spacer (ITS) region of ribosomal genes was performed on field and pathogenicity test leaf lesion samples to confirm the presence of P. teres f. maculata. DNA templates were prepared using the Extract-N-Amp Plant PCR Kits (Sigma Chemical Co., St. Louis, MO) and subjected to PCR using ITS1 and ITS4 primers. Amplicons were then purified and sequenced. The 585-bp nucleotide sequences of P. teres f. maculata from Mon-Dak area were submitted to GenBank under accession nos. PtmNES1 (JX187587), PtmSDY1 (JX187588), PtmSDY2 (JX187589), and PtmWIL1 (JX187590). The sequences from the four locations shared 100% similarity and also with P. teres f. maculata (EF452471) from GenBank while showing 10 nucleotide differences (99% similarity) with P. teres f. teres (EF452472). The results represent first report of SFNB in the Mon-Dak. Barley is one of the most important crops in the area. Resistance of the NFNB and SFNB of barley are controlled by different genes (4). Based on this report, SFNB therefore have to be considered in selection of barley cultivars for cultivation in the area.

However, due to the highly variable nature of precipitation and uncertain water availability, selection of a crop with assured positive net returns to add to the system to increase cropping frequency is a challenge in the absence of reliable seasonal precipitation forecasts. The objective of this study was to evaluate long-term yields and net returns of several potential summer crops at various soil water contents at planting to assess their potential use in increasing dryland cropping frequency. Three grain crops [corn (Zea maysL.), canola (Brassica napus), and proso millet (Panicum miliaceumL.)] and two forage crops [foxtail millet (Setaria italicaL. Beauv.) and spring triticale (X Triticosecalerimpaui Wittm.)] for which the Root Zone Water Quality Model (RZWQM2) had been calibrated at Akron, CO and/or Sidney, NE, were selected for investigation through modeling. The calibrated model was used to simulate yield responses of the crops to 25, 50, 75 and 100% of plant available water (PAW) in the soil profile at planting using recorded weather data from Akron, CO and Sidney, NE (1948-2008). Average costs of production and 10-yr average commodity prices for northeast Colorado were used to calculate net returns for each of the crops at the varying PAW levels. All crops showed significant (p<0.05) simulated yield increases in response to increasing initial PAW levels when those changes occurred in the entire 0-180cm soil profile. The two forage crops gave greater net returns than the three grain crops for all initial PAW levels when calculated with 10-yr average prices received. Among the grain crops, proso millet was slightly more profitable than corn at Akron, while corn was the least profitable crop at Sidney. Using current commodity prices (13 September 2011) resulted in proso millet being the least profitable crop at Sidney, while corn was the most profitable grain crop at Akron and showed net returns that were similar to those found for the forage crops. The results of this study may guide the selection of a spring- or summer-planted crop and help farmers assess risk as they contemplate intensifying the WF system by using a measure or estimate of PAW at planting.

AN - 1239061271; 23129480 AB - The mobility, longevity and termiticidal activity of chlorfenapyr applied to soils at the termiticidal labeled rate was evaluated for 30 months after treatment (MAT) in a greenhouse study. There was little dissipation of chlorfenapyr in soil treated at the labeled rate for perimeter treatments for the prevention and control of termite infestations. Chlorfenapyr was detected in soil immediately below the initially treated soil in the packed soil columns. This was likely due to settling of soil. The treated soil remained toxic to subterranean termites in 3 and 7 day bioassays over the duration of the study. The treated soil displayed slow-acting properties regarding toxicity to termites. Trace amounts of chlorfenapyr were detected in the eluates of packed soil cones. The commercial formulation of chlorfenapyr used in this study (21.45% concentrate diluted to 0.125% prior to application) killed 100% of the tested subterranean termites for at least 30 months.

AN - 1239059634; 22807277 AB - The possibility of improving the efficacy of various insecticides for codling moth, Cydia pomonella (L.), by the addition of a microencapsulated formulation of pear ester, ethyl (2E, 4Z)-2,4-decadienoate (PE-MEC, 5% AI), was evaluated in field trials in apple from 2005 to 2009. The addition of PE-MEC (<3.0 g AI ha(-1) ) significantly lowered fruit injury with low rates of organophosphate and neonicotinoid insecticides. The addition of PE-MEC (1.48 g AI ha(-1) ) to maximum label rates of insecticides with moderate activity for codling moth, such as ebamectin benzoate, spinosad and methoxyfenozide, significantly improved their effectiveness. However, PE-MEC did not consistently improve the activity of maximum label rates of either rynaxypyr or spinetoram. The addition of PE-MEC with seasonal spray programs of acetamiprid and azinphos-methyl in combination with the use of sex pheromones for mating disruption provided the most effective control. The addition of PE-MEC can improve the effectiveness of some insecticides for codling moth in apple. Insecticides active via dermal toxicity are more strongly improved by the addition of PE-MEC. Season-long use of PE-MEC can also augment the effectiveness of mating disruption. Adding PE-MEC to variable integrated management programs for C. pomonella should be further investigated.

However, the balance between competition and facilitation can change over the course of plant development. Determining when each interaction is important for plant productivity allows us to identify factors limiting plant growth. In this field study, neighbor removal mid-way through the growing season did not result in a size change for any species (Clarkia purpurea, Plantago erecta, and Micropus californicus) in the first year. In the second year, two species had greater biomass when neighbors were removed very early in the growing season, indicating a competitive effect. The third species neither benefited nor suffered from neighbor removal. In some years, P. erecta and M. californicus may be negatively affected by competition at early growth stages and are later unable to capitalize on newly-available resources after removals of competitors.

AN - 1151032734; 23135842 AB - Chemical mutagenesis of rice has been used extensively to generate useful genetic variation for the purpose of breeding improved varieties. More recently, advances in high-throughput genotyping platforms have enabled the efficient detection of point mutations generated by chemical agents. This in turn has renewed interest in using traditional chemical mutagenesis to generate mutant populations for gene discovery and functional characterization. Targeting of Induced Local Lesions in Genomes (TILLING) is a powerful reverse genetics method which combines chemical mutagenesis with the high-throughput discovery of point mutations. Numerous chemical mutagens have been shown to be effective in generating point mutations and small deletions in rice. This chapter describes the use of a combination of sodium azide (NaN(3)) and N-nitroso-N-methylurea to generate populations that are suitable for TILLING as well as forward genetics and mutation breeding.

Enhancing these models to take advantage of increasingly available and skillful seasonal climate outlook products would broaden applications to include pro-active soil and water resources management, better prediction of achieving production targets, and weather-related risk assessment. Here, an analytical method was developed that enables generation of daily precipitation time-series for seasonal forecasts up to twelve months ahead. The method uses historical weather observations to establish reference precipitation statistics (monthly precipitation amount, number of rainy days per month, wet-wet and dry-wet day transition probabilities) and subsequently adjusts these statistics to reflect the forecast departures from long-term average monthly precipitation. This reference forecast departure approach ensures that generated precipitation is consistent and compatible with the forecast and the local climate characteristics as well. The method was tested with precipitation data from the USDA-ARS weather station at Temple, TX, and NWS-COOP data at Tallahassee, FL, for a hypothetical seasonal precipitation forecast. Several 100-year time-series of generated daily precipitation reproduced average monthly precipitation within 6% of expected forecast values and Mean Absolute Error (MAE) of less than 3%, wet/dry day transition probabilities within 5% and MAE of less than 2%, and average number of rainy days per calendar month within 2% and MAE of less than 1 %. The successful testing of the method validated the approach, analytical solution, and implementation of the method in experimental climate generator SYNTOR. This forward looking capability of synthetic weather generation will benefit water resource managers, farm loan officers, agricultural consultants, risk management agencies, and anyone relying on seasonal climate forecast information for decision making.

AN - 1240906358; 23171393 AB - The metabolism of α- and γ-hexabromocyclododecane (HBCD) was investigated in adult C57BL/6 female mice. α- or γ-[(14)C]HBCD (3 mg/kg bw) was orally administered with subsequent urine and feces collection for 4 consecutive days; a separate group of mice was dosed and sacrificed 3 h postexposure to investigate tissue metabolite levels. Extractable and nonextractable HBCD metabolites were quantitated in liver, blood, fat, brain, bile, urine, and feces and characterized by LC/MS (ESI-). Metabolites identified were distinct between the two stereoisomers. In mice exposed to α-HBCD, four hydroxylated metabolites were detected in fecal extracts, and one of these metabolite isomers was consistently characterized in liver, brain, and adipose tissue extracts. In contrast, fecal extracts from mice exposed to γ-HBCD contained multiple isomers of monohydroxy-pentabromocyclododecene, dihydroxy-pentabromocyclododecene, and dihydroxy-pentabromocyclododecadiene, while in liver and adipose tissues extracts only a single monohydroxy-pentabromocyclododecane metabolite was observed. Both stereoisomers were transformed to metabolites which formed covalent bonds to proteins and/or lipids in the gut as suggested by high fecal nonextractables. The presence of tissue- and excreta-specific metabolic products after in vivo exposure to the two main HBCD stereoisomers supports previous toxicokinetic studies indicating that these two stereoisomers are biologically distinct. The distinct metabolic products identified in this study have the potential to aid in the identification of stereoisomer-specific HBCD exposures in future biomonitoring studies.

Although co-occurring factors including site nutritional deficiencies and punctuated stress events (e.g., defoliations, drought) are hypothesized to trigger white ash decline, there are no empirical assessments of these factors at regional scales. In this study, we evaluated ash crown dieback, crown health condition, and mortality on 190 plots paired along a topographic gradient known to differ in site nutrition across a 3000km2 area of northwestern Pennsylvania, USA. Additionally, we assessed white ash foliar nutrient content and additional factors including defoliation history as potential explanatory variables at all sites. White ash populations on upper slopes consistently had significantly greater dieback, poorer crown condition, and greater mortality than populations in paired plots on lower slopes. Despite nearly two decades since the last major elm spanworm defoliation, this stressor further amplified the differences in health and mortality seen between slope positions. On the relatively cation deficient upper slope positions, crown dieback and crown condition improved with increasing foliar cation (Ca2+, Mg2+) concentration. Our results indicate that white ash health is strongly influenced by site nutrition, and defoliation can trigger declines in cation-deficient sites. Knowledge of how landscape position and nutrition influence white ash health may alter management responses to insect outbreak events.

Evidence of historic burning has prompted the use of prescribed fire as a tool to improve the competitive status of oak regeneration in mature stands. A primary shortfall of fire effects research in oak forests has been a lack of long-term studies on the effects of multiple fires. Here we describe the effects of repeated fires on stand structure and tree regeneration over a 13-year period in mature mixed-oak forests located in southern Ohio, USA. Three stands were burned 3-5 times from 1996 to 2005 with low-intensity dormant-season fires, and two stands remained unburned. Woody vegetation was sampled periodically on nine 0.125ha plots per stand. Plots were located across the upland landscape and were characterized by an Integrated Moisture Index. Fire altered stand structure by reducing the density of large saplings (3.0-9.9cm DBH) and midstory trees (10-25cm DBH) by 76% and 34%, respectively. Fire had little impact on trees >25cm DBH. Small saplings (1.4m tall to 2.9cm DBH) were dynamic over time on dry plots that were burned. After being repeatedly topkilled from year 1-8, the small sapling layer had redeveloped on dry burned plots by year 13 and species composition had shifted from dominance by shade-tolerant species to a more equal distribution of shade-tolerants, oaks+hickories, and sassafras. The density of oak+hickory and sassafras advance regeneration (stems 30cm tall to 2.9cm DBH) was significantly greater on burned plots than on unburned plots in year 13, though variability among plots was high. Advance regeneration of shade-tolerant species was equally abundant on burned and unburned plots. Density of oak+hickory advance regeneration in year 13 was positively related to its weighted frequency (a surrogate for size and abundance) in year 0 (r2=0.67, p<0.0001) and inversely related to stand density (r2=0.33, p<0.0001) and canopy cover (r2=0.31, p<0.0001), both of which were reduced by fire. Although oak+hickory advance regeneration was more abundant on burned plots, we conclude that other methods (e.g., herbicide, partial cutting) are necessary to further reduce stand density and promote the development of larger oak+hickory regeneration, particularly on mesic sites.

One approach to diversification is to convert predominantly even-aged, pure red pine stands to multi-cohort, mixed-species forests through variable overstory retention at harvest. Based on limited empirical evidence, pathologists have advised against this multi-cohort approach in stands where pathogens causing damaging shoot blight diseases are established. We examined disease incidence among planted red, jack (Pinus banksiana), and white pine (Pinus strobus) in a variable retention harvest and understory woody vegetation removal (brushing) experiment in northern Minnesota. The experiment included four overstory treatments (dispersed and two aggregated overstory retention treatments and a control, N=4) that were split by an understory brushing treatment (yes or no). Prior to harvest in 2003, the fungal pine pathogens Diplodia pinea, Sirococcus conigenus and Armillaria solidipes (syn. Armillaria ostoyae) were common on the study site. Within 6years after harvest, these pathogens reduced the survival of planted red, white and jack pine, potentially interfering with long-term management objectives. Across all treatments, shoot blight incidence was generally higher in dead red and jack pine than white pine seedlings and was predominantly caused by D. pinea. The disease killing white pine seedlings was predominately Armillaria root rot. Overstory treatment affected the percentage of jack and white pine seedling mortality attributable to shoot blight, but not the more susceptible red pine, with greater overstory retention resulting in greater disease incidence. Understory brushing had no effect on the incidence of shoot blight on seedlings. We expect disease to continue to influence stand structure and composition across all treatments. Our study results highlight the need for forest managers to assess long-term risk of potentially damaging pathogens in red pine stands prior to harvest and use that information to guide decisions regarding silvicultural practices to increase age and species diversity.

Twelve snakes involved in a public outreach program, representing seven different species, were tested weekly for shedding of Salmonella sp. over a period of 10 consecutive weeks. The snakes were housed in close proximity but in separate exhibits. Fresh fecal samples (when available) or cloacal swabs were cultured for Salmonella sp., and subsequent Salmonella isolates were serotyped. As representatives of the feed source, the feces of two mice and the intestines of one rat were cultured weekly. Fecal samples from 11 of the 12 snakes were positive for Salmonella at least once. Seven (58%) of 12 snakes were culture positive five times or more. The weekly prevalence of Salmonella shedding varied between 25% and 66%. Two or more different serotypes were isolated from nine snakes over time; however, a predominant serotype was generally isolated from each of these snakes. Altogether 15 different serotypes were identified. Serotypes of public health concern included Newport, Oranienburg, and Muenchen. Two samples from feeder rodents were positive for Salmonella. The results are consistent with previous studies showing high intestinal colonization rates with Salmonella sp. in snakes. Frequent and intermittent shedding of multiple serotypes was evident. Feeder rodents might serve as a source for intestinal colonization. Appropriate handling protocols should be implemented for all reptiles associated with public outreach programs to minimize risk of Salmonella transmission to the public.

AN - 1223432741; 23153034 AB - The spiroketal (E)-conophthorin has recently been reported as a semiochemical of the navel orangeworm moth, a major insect pest of California pistachios and almonds. Conophthorin and the isomeric spiroketal chalcogran are most commonly known as semiochemicals of several scolytid beetles. Conophthorin is both an insect- and plant-produced semiochemical widely recognized as a nonhost plant volatile from the bark of several angiosperm species. Chalcogran is the principal aggregation pheromone component of the six-spined spruce bark beetle. Recent research has shown conophthorin is produced by almonds undergoing hull-split, and both spiroketals are produced by mechanically damaged almonds. To better understand the origin of these spiroketals, the volatile emissions of orchard fungal spores on fatty acids common to both pistachios and almonds were evaluated. The volatile emission for the first 13 days of spores placed on a fatty acid was monitored. The spores investigated were Aspergillus flavus (atoxigenic), A. flavus (toxigenic), Aspergillus niger, Aspergillus parasiticus, Penicillium glabrum, and Rhizopus stolonifer. The fatty acids used as growth media were palmitic, oleic, linoleic, and linolenic. Spores on linoleic acid produced both spiroketals, those on linolenic acid produced only chalcogran, and those on palmitic and oleic acid did not produce either spiroketal. This is the first report of the spiroketals conophthorin and chalcogran from a fungal source.

The spatial variability of surface energy fluxes across short distances in a sand-sagebrush ecosystem AN - 1785248867; 17338630 AB - During the summer of 2001, the spatial variation of the surface energy fluxes across short distances, 16m to 32m, was examined over a sagebrush steppe ecosystem in northeastern Colorado. Two eddy covariance micrometeorological stations were used to test the hypothesis that fine-scale variations in the physical properties of the site result in significant variation in the surface energy balance. Through a comparative analysis of the flux measurements, it was found that statistically significant variations in the sensible, latent and soil heat fluxes were present at the study site. These variations were linked to small changes in the near-surface soil moisture content and leaf area index. The results of this study suggest there may be substantial uncertainty surrounding a single point measurement when it is used to represent the exchange of heat and moisture over a large area. This uncertainty must be considered when using in-situ measurements to evaluate remote sensing products or numerical models.

Leuconostoc mesenteroides (LM), Bacillus atrophaeus (BA) or Pseudomonas aeruginosa (PA) aliquots were exposed on nutrient agar plates to Array 1 (AR1, 0.2 mW cm super(-2)) or Array 2 (AR2, 80 mW cm super(-2)), which emitted impure or pure blue light (0-300 J cm super(-2)), respectively. Inoculated control (room light only) plates were incubated (48 h) and colonies enumerated. The antifungal properties of blue light combined with ERY (11.4 and 22.8 mu mol l super(-1)) on Penicillium digitatum (PD) and Fusarium graminearum (FG) conidia were determined. Conidial controls consisted of: no light, room light-treated conidia and ERY plus room light. Light-treated (ERY + blue light) conidial samples were exposed only to AR2 (0-100 J cm super(-2)), aliquots spread on potato dextrose agar plates, incubated (48 h, 30 degree C) and colonies counted. Blue light alone significantly reduced bacterial and FG viability. Combined with ERY, it significantly reduced PD viability. Blue light is lethal to bacteria and filamentous fungi although effectiveness is dependent on light purity, energy levels and microbial genus. Significance and Impact of the Study Light from two arrays of different blue LEDs significantly reduced bacterial (Leuconostoc mesenteroides, Bacillus atrophaeus and Pseudomonas aeruginosa) viabilities. Significant in vitro viability loss was observed for the filamentous fungi, Penicillium digitatum and Fusarium graminearum when exposed to pure blue light only plus a photosensitizer. F. graminearum viability was significantly reduced by blue light alone. Results suggest that (i) the amount of significant loss in bacterial viability observed for blue light that is pure or with traces of other wavelengths is genus dependent and (ii) depending on fungal genera, pure blue light is fungicidal with or without a photosensitizer.

Latent ( lambda E) and sensible heat (H) fluxes were linear functions of available energy, and seasonality had a major effect on the partitioning of available energy into lambda E and H at each stand. Both defoliation and prescribed fire reduced leaf area, altered the partitioning of available energy, and reduced lambda E flux compared to undisturbed periods. Summer daily Et averaged 4.2 plus or minus 1.5, 3.3 plus or minus 1.2 and 3.9 plus or minus 1.3mm day-1 at the oak-, mixed, and pine-dominated stands during undisturbed periods, but only 2.4 plus or minus 0.9mmday-1 during defoliation at the oak stand in 2007, and 2.4 plus or minus 0.9 and 3.2 plus or minus 0.9mmday-1 following spring fires at the mixed and pine-dominated stands, respectively. For all years measured, seasonal maximum leaf area index (LAI) explained 82% of the variability in daily Et during the summer at the oak stand, and 80% of the variability at the mixed and pine-dominated stands. Annual Et averaged 614, 493, and 683mmyr-1 at the oak, mixed, and pine stands, respectively. When averaged across all stands and years, annual Et was 606mmyr-1, ca. 53.6% of incident precipitation, and similar to long-term averages reported in other studies in the Pinelands. Gypsy moth defoliation potentially reduced Et by ca. 31mmyr-1 across all upland forests in 2007, resulting in a 7.3% increase in groundwater recharge. Our research indicates that non-stand replacing disturbances can have significant effects on energy partitioning, and can reduce Et at the stand and landscape scales.

Nutrient limitation, however, results from a deficiency mainly in nitrogen (N) or phosphorus (P) levels relative to cellular growth needs. Limitation is a function of biotic and abiotic factors, the latter including land-use activities (e.g., agriculture, septic systems) and underlying bedrock features. The purpose of this study was twofold: (1) to assess the relationship between algal biomass and ambient nutrient levels along the longitudinal course of a river through a transition from weak to well-developed underlying karst bedrock and (2) experimentally assess if periphyton was N- or P-limited between weak and well-developed karst reaches. Sestonic and Cladophora biomass (=chlorophyll-a) levels increased sharply along the longitudinal gradient. Cladophora biomass, in particular, was strongly correlated with nitrate levels. In contrast, periphyton biomass (=chlorophyll-a) levels were sporadic and did not display a longitudinal pattern. With the exception of ammonia, individual nutrient levels generally increased longitudinally and were higher in the downstream karst reaches. Total N/total P ratios also increased longitudinally and were >25 throughout the study region, suggesting P limitation. The results of the nutrient limitation studies, however, coupled with high concentrations of both N and P throughout the study reach in excess of eutrophication thresholds, suggest that total nutrients are not limiting within the study region. Overall, Kentucky's upper Green River appears to be a nutrient-enriched, eutrophic system and particularly in the downstream, well-developed karst reaches.

Measurements are commonly done using well-established techniques such as eddy covariance (EC) and weighing lysimetry, but implementing these to collect spatially distributed observations is complex and costly. Two techniques that could simplify flux observations are the surface renewal (SR) and flux variance (FV) approaches. These methods infer sensible heat fluxes from high frequency observations of near surface air temperatures using low cost thermocouples. In combination with net radiation and soil heat flux observations, surface renewal and flux variance observations produce latent heat fluxes as a residual of the surface energy balance. The viability of these techniques was tested in a strongly advective irrigated agricultural setting as part of the Bushland Evapotranspiration and Agricultural Remote Sensing Experiment in 2008 (BEAREX08). Using 20Hz air temperature data collected between 12 June and 13 August from two cotton field sites and one senescent/dormant grass site, sensible heat flux estimates were computed. Surface flux conditions ranged widely and include episodes of latent heat fluxes exceeding net radiation. Overall, flux estimates from SR and FV were similar to simultaneously obtained eddy covariance observations on most days. During strong advection neither approach closely agreed with EC data, although the surface renewal technique more reliably estimated the correct sign of sensible heat fluxes. Both techniques were found to offer flux estimates comparable to EC data, though with different advantages. SR is self-contained, requiring no additional instrumentation beyond air temperature equipment. SR correctly diagnosed the sign of sensible heat fluxes and produced better estimates at early morning and late afternoon times than FV, although these were achieved after lag time selection using EC data for calibration. FV, by contrast, required wind speed observations, as well as thermal infrared data to resolve heat flux directions. However, using nominal parameters and no local calibration, FV produced mid-day estimates equal to or better than SR. These outcomes indicate that flux data with accuracies approaching EC capabilities is feasible with the potential for reduced deployment complexity and cost.

This information is particularly critical in arid climates where freshwater resources are limited or expensive, and groundwater supplies are being depleted at unsustainable rates to support irrigated agriculture as well as municipal and industrial uses. Gridded evapotranspiration (ET) information at field scales can be obtained periodically using land-surface temperature-based surface energy balance algorithms applied to moderate resolution satellite data from systems like Landsat, which collects thermal-band imagery every 16days at a resolution of approximately 100m. The challenge is in finding methods for interpolating between ET snapshots developed at the time of a clear-sky Landsat overpass to provide complete daily time-series over a growing season. This study examines the efficacy of a simple gap-filling algorithm designed for applications in data-sparse regions, which does not require local ground measurements of weather or rainfall, or estimates of soil texture. The algorithm relies on general conservation of the ratio between actual ET and a reference ET, generated from satellite insolation data and standard meteorological fields from a mesoscale model. The algorithm was tested with ET retrievals from the Atmosphere-Land Exchange Inverse (ALEXI) surface energy balance model and associated DisALEXI flux disaggregation technique, which uses Landsat-scale thermal imagery to reduce regional ALEXI maps to a finer spatial resolution. Daily ET at the Landsat scale was compared with lysimeter and eddy covariance flux measurements collected during the Bushland Evapotranspiration and Agricultural Remote sensing EXperiment of 2008 (BEAREX08), conducted in an irrigated agricultural area in the Texas Panhandle under highly advective conditions. The simple gap-filling algorithm performed reasonably at most sites, reproducing observed cumulative ET to within 5-10% over the growing period from emergence to peak biomass in both rainfed and irrigated fields.

Here we report a new irrigation experiment designed to quantify interflow thresholds and reveal subsurface mixing processes during steady state flow conditions over a 12 mX16.5 m plot draining to an interflow interception trench. Dye tracers were applied on surface transects prior to irrigation, and bromide (conservative tracer), nitrate, ammonium, and phosphorus (reactive tracers) were added at constant concentrations to the irrigation water drawn from a deep aquifer with a distinct isotopic signature. 417 mm of water were applied over 51 hours, and drainage conditions were monitored for a week following irrigation. Interflow in the two drains commenced after 131 and 178 mm, and flow rates diminished immediately after irrigation ceased, although interflow continued for four more days. Over the experiment, 199 mm of water (49% of applied water) appeared as interflow. Dye tracers moved rapidly with the wetting front, with peak concentrations measured shortly after flow commencement, suggesting saturated topsoil conductivities of 0.5 to 1.5 m/hr. No preferential flow was observed during this experiment or previously during rainfall events at the trench face. Bromide concentrations and the new water fraction rose steadily throughout irrigation, peaking about 16 hours after irrigation ceased. Ammonium and phosphorus concentrations at the trench face were low, suggesting rapid uptake or sorption, while nitrate concentrations were higher, suggesting more conservative transport. Our two collection drains showed identical temporal variation in bromide concentrations but consistently different new/old water fractions, indicating differences in flow paths and storages within the plot. These data suggest that tightly bound soil water exchanged with new water throughout the experiment, and that a significant portion of flowing old water must have originated from the argillic layer beneath the sandy loam topsoil. Inferences from the isotopic signature of the outflow water were consistent with the bromide data. Piezometric and outflow data all point to fill and spill effects on interflow generation in this low relief site.

Setting up a finite difference or finite element model takes valuable time that often is not available when decisions need to be made quickly. An analytic element model (AEM), GFLOW in this case, may enable the investigator to produce a preliminary steady-state model for a watershed, and to easily evaluate variants of the conceptual model. Use of preexisting data, such as stream gage data or USGS reports makes the job much easier. Solutions to analytic element models are obtained within seconds. The Eagle Creek watershed in central New Mexico is a site of local water supply issues in an area of volcanic and plutonic rocks. Parameters estimated by groundwater consultants and the USGS, and discharge data from three USGS stream gages were used to set up the steady-state analytical model (GFLOW). Matching gage records with line-sink fluxes facilitated conceptualization of local groundwater flow and quick analysis of the effects of steady water supply pumping on Eagle Creek. Because of steep topgraphy and limited access, a water supply well is located within the stream channel within 20 meters of the creek, and it would be useful to evaluate the effects of the well on stream flow. A USGS report (SIR 2010-5205) revealed a section of Eagle Creek with a high vertical conductivity which results in flow loss of up to 34 l/s (including flow to the water table and flow into alluvium) when the well was pumped and the water table was lowered below the channel bottom. The water supply well was simulated with a steady-state well pumping at the average and maximum rates of 12 l/s and 31 l/s. The initial simulation shows that pumping at these rates results in stream flow loss of 19% and 51%, respectively. The simulation was conducted with average flow conditions, and this information will be important in planning for management during periods of drought, as well as times of more normal precipitation; as water uses must be balanced with the needs of the existing ecosystem. Alternatives, such as low conductivity blocks between stream channels and different volumetric and geographic pumping scenarios may also be readily explored in an AEM. Exporting these scenarios into MODFLOW simulations will enable us to evaluate transient and cyclical pumping effects on the surface waters for each AEM conceptualization, as well as being able to simulate seasonal recharge. However, in many cases the use of MODFLOW may not be necessary, if the AEM proves sufficient to answer the relevant questions. Symbiotic use of GFLOW and MODFLOW will be an invaluable aid in evaluating groundwater and its uses in National Forest watersheds, especially in cases when time is a critical factor in informed decision-making.

In this study, over 3,200 observations of permafrost occurrence within the top 1 m of soil and their organic layer thicknesses in Interior Alaska were investigated for their relationships with climate variables and topographical and soil texture gradients. Permafrost and organic layer thickness are tightly coupled in a nonlinear pattern. Permafrost occurrence increases sharply as the organic layer thickens from 0 to 37 cm, but then decreases slowly after 37 cm, indicating a change from drained to saturated conditions (see figure). As growing season length increased, the probability of permafrost occurrence decreased for all landform types. In contrast, organic layer thickness tended to increase in flat and low sloped areas as growing season length increased, but upland areas had no change or slightly decreasing organic layer thickness. Further, organic layer thickness in sandy soil types showed less sensitivity to growing season length than other soil types. Predicted quantities of permafrost occurrence and organic layer thickness are much less certain than their direction. Nonetheless, if it is assumed that the observations represent all of Interior Alaska, extrapolating the results shows that when growing season length increases by 5 days, the percent area with permafrost within Interior Alaska decreases from 39% to 23%. Under the same conditions, mean organic layer depth increases by 3.5 cm and the percent area with saturated soils (i.e. >37 cm organic layer thickness) increases from 12% to 15%. Our results indicate obvious consequences for the carbon cycle in this region under warming conditions where increased carbon storage in the organic layer may offset an unknown carbon loss in the mineral soil as permafrost thaws.

There has been increasing concern over the potential adverse effects of large wildfires on runoff, erosion, and water quality, and this has led to extensive forest thinning projects to reduce the potential for high-severity wildfires. The initial goal of this project was to evaluate the effects of thinning at the hillslope scale using sediment fences and the small catchment scale by installing flumes and periodically monitoring water quality and channel morphology. The hillslope measurements began in mid-2001, and the flumes were installed in early summer 2002. In 2001 only 3 of the 40 hillslopes produced sediment. In June 2002, the Hayman fire burned half of the study sites. Mean percent ground cover decreased from 90% to 6% in the sites burned at high severity, and the soils were strongly water repellent from the surface to a depth of 6 or 9 cm. The first two storms of 11 and 17 mm caused extensive rilling in the formerly unchannelled swales and extensive downstream gullying. Erosion rates averaged 7.5 Mg ha-1 in the dry summer of 2002 and 10.7 Mg ha-1 in the wet summer of 2003. Thinning in the remaining unburned swales decreased the mean vegetative cover from 15% to 7% and increased the mean percent bare soil from 8% to 16%. However, 75% ground cover meant that no sediment was generated from any of the thinned or the control hillslopes from 2002 through 2006. At the small watershed scale, the observed high water marks were as much as 1.4 m above the estimated bankfull stage. The Saloon Gulch flume was completely buried by the post-fire deposition, and the nearly continuous deposition in the Brush Creek flume precluded accurate flow measurements. Potassium, magnesium, calcium, chloride and nitrate concentrations approximately doubled after the fire. Turbidity increased substantially, while the pH remained unchanged. These results clearly show the dramatic difference between the effects of thinning and high severity fires on runoff, erosion, and sediment delivery at both the hillslope and watershed scales.

The influence of soil erosion on the global carbon (C) cycle is the result of three ecologically relevant factors: (1) changes in molecular composition of the organic matter (OM); (2) physical protection of OM within aggregates and pores; and (3) organomineral associations of OM with soil minerals through chelation and/or cation-bridging. Previous research has shown that prevalent OM stabilization mechanisms vary by landform position, where long-residence times of OM were associated with aggregation and cation-bridging in eroding positions, while OM in low-lying depositional areas was protected through burial and association with metal oxides. However, it is still unclear how OM stabilization mechanisms shift with extended transport from the source watershed. We addressed this issue by comparing soil from slope transects with sediment captured after it was transported from watersheds in the southern Sierra National Forest. Using a sequential extraction procedure, we separated organic particles (OP) and OM fractions that were water-extractable (free), aggregate-protected, or bonded to mineral surfaces through cation bridging to assess differences in stabilization mechanisms between landform positions and sediment. While the C:N ratio is consistent between years and watersheds, absolute C and N concentrations vary more in sediments than in the soils. Confirming previous work, there was little difference in free OP fraction between landform positions. However we found that this free OP fraction was often enriched in the sediment samples over the soils from the source watershed; the intensity of this signal differed by year. In addition, organomineral bonding also differed between sediments and soils. Of the five major polyvalent ions (Ca, Fe, Mg, Mn, and Al) that we measured in liquid extracts, calcium and iron were more closely correlated to C concentrations in sediments than in soils. Preliminary analysis of particle size distribution indicates that soil texture, particularly silt, is a controlling factor for C storage in complexed OM. Because these entisols and inceptisols have little clay, the potential for OM stabilization through these mechanisms is likely higher in other soils. Understanding which mechanisms of OM stabilization dominate before and after erosion will allow us to estimate the changing decomposition potential of this OM - including whether it results in a net carbon source, or a carbon sink, as seen in several other ecosystems.

These areas are characterized by low and highly variable precipitation where potential evapotranspiration exceeds precipitation. In Arizona, 94% of tributary streams to major rivers are intermittent or ephemeral based on the National Hydrography Dataset. This presentation addresses the hydrologic and ecological influence of ephemeral and intermittent streams on perennial or intermittent rivers in the arid and semiarid southwestern United States with particularly emphasis on Arizona and New Mexico. The heavily studied San Pedro Basin in southeastern Arizona provides a uniquely thorough understanding of the evidence for the function and connectivity of ephemeral and intermittent tributaries to the perennial main stem of the San Pedro River. Flows and floods from ephemeral tributaries are a major driver of the dynamic hydrology of the San Pedro River. They also supply water to main stem alluvial aquifers and regional groundwater aquifers, both of which supply perennial river baseflow and support riparian communities. In addition, ephemeral streams export sediment, which contributes to shaping the fluvial geomorphology and alluvial aquifers of the San Pedro River, and nutrients, which contribute to river productivity.

In this study, we examine retail lunch meat data from Nielsen 2006 Homescan. The objective of this study is to determine the impact of retail prices, expenditure, and demographic variables on eight lunch meat products. A censored AIDS model is used to estimate the demand for lunch meat products. Results reveal that own-price elasticities are elastic for all lunch meat categories. The expenditure elasticities are elastic for four lunch meat products and inelastic for the remaining products and demographic variables have statistically significant impacts on lunch meat purchases.

AN - 1492625974; 18930530 AB - The aim of this study was to examine the phytotoxicity of cadmium (Cd) on commonly measured physiological parameters [root and shoot growth inhibition, dry mass (DM) and fresh mass (FM) production, water content (WC), Cd accumulation] and biochemical parameters [photosynthetic pigments (chlorophyll a, b, total carotenoids), proteins, thiobarbituric acid reactive substances (TBARS), and protein sulfhydryl group content] using regression analyses. Biochemical parameters were evaluated to estimate oxidative stress in seedlings. For all parameters, the sensitivity of Hordeum vulgare L. and Sinapis alba L. plants was studied as representative of widely cultivated crop plants. Cd showed a greater inhibitory effect on root than shoot growth, predominantly in S. alba. In addition to growth inhibition, Cd reduced biomass production (FM, DM), mainly in the shoots. Although Cd was accumulated chiefly in the roots, the accumulation of Cd in S. albashoots exceeded that in H. vulgare. While Cd resulted a greater reduction of chlorophyll b than chlorophyll a, carotenoids content in S. alba increased when metal concentration reached 71 and 143 mg Cd l super(-1). The adverse effect of Cd was also confirmed by a significant reduction in protein sulfhydryl groups. In a regression analysis, positive correlations were observed between proteins and sulfhydryl groups in shoots ofS. alba and TBARS and sulfhydryl groups in H. vulgare, while negative correlations were found between Cd concentrations in S. alba roots and proteins, TBARS, and WC contents. Cd concentration in H. vulgare roots was also negatively correlated with TBARS and shoot length.

ODOR ACTIVITY VALUE AN - 1448213287; 17688075 AB - There is a growing concern with air and odor emissions from agricultural facilities. A supplementary research project was conducted to complement the U.S. National Air Emissions Monitoring Study (NAEMS). The overall goal of the project was to establish odor and chemical emission factors for animal feeding operations. The study was conducted over a 17-month period at two freestall dairies, one swine sow farm, and one swine finisher facility. Samples from a representative exhaust airstream at each barn were collected in 10 L Tedlar bags and analyzed by trained human panelists using dynamic triangular forced-choice olfactometry. Samples were simultaneously analyzed for 20 odorous compounds (acetic acid, propanoic acid, butyric acid, isobutyric acid, valeric acid, isovaleric acid, hexanoic acid, heptanoic acid, guaiacol, phenol, 4-methylphenol, 4-ethylphenol, 2-aminoacetophenone, indole, skatole, dimethyl disulfide, diethyl disulfide, dimethyl trisulfide, hydrogen sulfide, and ammonia). In this article, which is part 6 of a six-part series summarizing results of the project, we investigate the correlations between odor concentrations and odor activity value (OAV), defined as the concentration of a single compound divided by the odor threshold for that compound. The specific objectives were to determine which compounds contributed most to the overall odor emanating from swine and dairy buildings, and develop equations for predicting odor concentration based on compound OA Vs. Single-compound odor thresholds (SCOT) were statistically summarized and analyzed, and OA Vs were calculated for all compounds. Odor concentrations were regressed against OA V values using multivariate regression techniques. Both swine sites had four common compounds with the highest OA Vs (ranked high to low: hydrogen sulfide, 4-methylphenol, butyric acid, isovaleric acid). The dairy sites had these same four compounds in common in the top five, and in addition diethyl disulfide was ranked second at one dairy site, while ammonia was ranked third at the other dairy site. Summed OAVs were not a good predictor of odor concentration (R(2) = 0.16 to 0.52), underestimating actual odor concentrations by 2 to 3 times. Based on the OAV and regression analyses, we conclude that hydrogen sulfide, 4-methylphenol, isovaleric acid, ammonia, and diethyl disulfide are the most likely contributors to swine odor, while hydrogen sulfide, 4-methyl phenol, butyric acid, and isovaleric acid are the most likely contributors to dairy odors.

Total sugar yield and multiple harvests can directly affect ethanol production cost. Little is known about stem traits and multiple harvests that contribute to sugar yield in sweet sorghum. Stem traits were evaluated from 25 sweet and grain sorghum accessions. Stems were harvested twice at the soft-dough stage and the stems were pressed with a hydraulic press. Sugars in the stem juice were quantified by high performance liquid chromatography. Sweet sorghum produced five times more fresh stem weight and dry stem mass (830 gand164 g) than grain sorghum (150 gand27g). Sweet sorghum produced a much higher volume of juice and higher yield of sugars (366 ml and42 g) per stem than grain sorghum (70 ml and4 g). Significant variability in fresh stem weight (72 - 1837 g), juice volume (31 - 753 ml), sugar yield (3 - 81 g), dry stem mass (14 - 383 g), and sugar yield/dry stem mass ratio (0.11 - 0.53) per stem was detected among sweet sorghum accessions. Stem sugar yield was significantly correlated with stem fresh weight and juice volume. Sorghum was harvested twice within one growing season resulting in some sweet sorghum accessions producing double amount of sugars. Sweet sorghum produced three times more dry mass weight (bagasse) than fermentable sugar weight. To reduce feedstock cost, methods have to be developed for efficiently utilizing bagasse. Our results showed high fresh stem weight, high ratio of sugar yield to dry stem mass, and double harvests are prime traits to boost sugar yield. Sweet sorghum may be suitable for multiple harvests in certain regions of theU.S.TheU.S.sweet sorghum collection needs to be screened for acces- sions that can be harvested twice with an extended feedstock-production season and used as a feedstock for sustainable and renewable bioenergy production.

In response to public concern over Oneida Lake, the United States Department of Agriculture Wildlife Services and the New York State Department of Environmental Conservation initiated an integrated research, management and monitoring program aimed at mitigating cormorant impacts to fisheries and other natural resources in 1998. The history of this program was reviewed and efforts to reduce negative impacts of the Double-crested Cormorant population in central New York described. Management was successful, as demonstrated by a substantial decrease in cormorant use of Oneida Lake during spring, summer and fall seasons, and the apparent recovery of certain sportfish populations. Research identified cormorant movement patterns within and among water bodies and documented cormorant responses to hazing and other management techniques. The cormorant management program in central New York was intended to keep cormorant use of Oneida Lake at a level that prevents unsustainable impacts to fisheries populations.

The current symposium built on previous efforts and described a number of focus areas of informational need, including cormorant impacts on natural resources, demographics of cormorants, assessment of control efforts, assessment of fish consumption and bioenergetics, and cormorant spatial ecology and influences on movements. The cormorant symposium highlighted a shift in research focus relative to earlier symposia, from evaluating potential impacts on commercial and natural resources to evaluating management actions in attaining desired goals. In addition, the symposium addressed the pressing need to obtain baseline information on cormorant population demographics. The shift reflects a response to increasing management efforts and intensity in North America and the need to understand the effects and effectiveness of increased cormorant control at several spatial scales. The symposium furthered communication and the sharing of information on cormorant issues in North America. However, uncertainty regarding impacts to cormorants associated with policy changes and management actions and outcomes presents significant future challenges.

Movement data were analyzed from 28 cormorants captured in Alabama, Arkansas, Louisiana and Mississippi and equipped with satellite transmitters. Four (three immature, one adult) cormorants did not migrate and stayed in the southeastern U.S. throughout the year. During spring, cormorants captured in Alabama migrated east of the Mississippi River and primarily west of the Appalachian Mountains. Cormorants from Arkansas, Louisiana and Mississippi migrated north along the Mississippi River Valley, the Missouri River Valley and/or the Ohio River Valley. The earliest departure for spring migration was 26 March, whereas the latest departure was 12 May. Adult cormorants departed for spring migration earlier than immature cormorants. The average departure date for fall migration was 1 October. Mean duration of spring migration was twelve days, and cormorants traveled an average of 70 km per day.

These cormorants commonly foraged at commercial aquaculture facilities and thereby came into conflict with farmers. Various interest groups are seeking ecologically sound strategies for minimizing the effects of burgeoning cormorant populations. Therefore, this study was conducted to estimate winter and summer home ranges of cormorants captured in the southeastern U.S. and determine whether age class, body mass, density of aquaculture facilities and availability of roost sites influenced size of these home ranges. Mean plus or minus SE home range size and core use area of satellite transmitter-marked cormorants wintering in the southeastern U.S. from 1999 to 2001 were 17,490 plus or minus 1,986 km2 (N = 37) and 1,550 plus or minus 265 km2 (N = 37), respectively. Winter home range size was not affected by region, age class or body mass. Summer home range and core use area of marked cormorants was 30,547 plus or minus 6,197 km2 (N = 6) and 3,124 plus or minus 1,019 km2 (N = 6), respectively.

The objective was to describe cormorant (N = 26/year) movements, specifically during the period of reproductive management by egg-oiling and seasonally (breeding, migration and wintering). Egg-oiling at two-week intervals resulted in a hatch success on LGI of 5.7% for 2000 and 2001, combined. The majority (97%) of core use areas of marked cormorants contained LGI throughout three egg-oiling treatments (six weeks), and 71% still contained LGI by the end of the final (fourth) treatment (eight weeks). Of cormorants that moved during or after control activities, three remained in the vicinity of active breeding colonies for over three months. Cormorants initiated fall migration over a 16-week period ranging from 12 July to 29 October, with a mean departure date of 6 September (N = 24, SE = 8 days) over both years. Mean duration of fall migration was 34 days (N = 19, SE = 7 days, range = 108 days). Most (75%) cormorants captured at LGI migrated east of the Appalachian Mountains, and their winter range extended from southeastern Louisiana, along the coast of the Gulf of Mexico, to the southern portion of the Atlantic coast. Although three (13%) cormorants over both years relocated to other active colonies for long enough periods (over three months) to potentially raise young, this study indicates that control efforts did not result in complete abandonment of LGI. Egg-oiling was successful in reducing recruitment within breeding seasons, and within-breeding-season renesting attempts by cormorants in this study were limited and likely unsuccessful. Further evaluation and refinement of egg-oiling as a management tool will require multiyear monitoring of the LGI cormorant breeding colony.

While crop growth models such as CERES-Maize provide the ability to evaluate numerous management scenarios without the costs associated with multiyear field experiments, recent studies have shown that CERES-Maize performs well under full irrigation but overestimates ET of corn under limited irrigation management. The primary objective of this study was to improve CERES-Maize ET simulation under limited irrigation management while maintaining accuracy of other important model output responses. Field experiments with corn were performed in northern Colorado, USA from 2006 to 2010, where four replicates each of full (ET requirement supplied by irrigation throughout the season) and limited (no irrigation before the V12 growth stage unless necessary for emergence, then full irrigation afterwards) irrigation treatments were analyzed. The local sensitivity of model input parameters affecting ET was evaluated, prompting changes to the model code with a new dynamic crop coefficient (KCD) as a function of the crop leaf area index. The modified CERES-Maize model more accurately represented ET under full and limited irrigation, for example reducing late-season ET potential from a plant with reduced canopy and more closely matched FAO-56 crop coefficient curves under full irrigation. Using the limited irrigation data for evaluation, the modified model showed significant decreases in model error for seasonal cumulative ET (root mean square deviation RMSD from 80.9mm to 49.9mm) and water productivity (RMSD from 5.97kgha-1mm-1to 2.86kgha-1mm-1) as compared to the original model. The modified model was subsequently applied to several hypothetical irrigation management strategies, indicating that reducing weekly vegetative stage water applications from 20mm to 2.5mm can increase simulated water productivity by over 15%. While these synthetic water production functions may not be feasible in a production field with natural climate variability, the modified ET model indicates promise for limited irrigation management increasing water productivity.

Treatments included roller (present or absent), in-row subsoiler (wide and narrow strips), and row-cleaners attached either to subsoiler, planter, or both. Rye was terminated with glyphosate (both rolled and non-rolled rye) in mid-April, and tillage treatments were applied; cotton was planted three weeks after tillage. In 2007, generally higher cotton stands were associated with rolled rye residue (137,134 plants/ha) vs. non-rolled rye (115,641 plants/ha). On average, significantly higher cotton seed yield was found for rolled rye (4,540 kg/ha compared to non-rolled rye (4,332 kg/ha). Examining specific treatments, the highest cotton seed yield (4,933 kg/ha) was associated with rolled rye under narrow strip tillage with row cleaners attached to both subsoiler and planter. The lowest cotton yield (3,913 kg/ha) was associated with non-rolled residue, under narrow strip tillage with row cleaners present on both subsoiler and planter. In 2008, no difference was found in cotton stand for rolled (108,375 plants/ha) and non-rolled rye (107,719 plants/ha). Cotton seed yield was higher in 2008 than in 2007 due to a severe drought in Alabama during 2007. In 2008, slightly higher cotton yield was reported for non-rolled rye (5,658 kg/ha) vs. rolled rye (5,419 kg/ha). The non-rolled rye, narrow strip subsoiling, and row cleaners on subsoiler generated the highest cotton yield (5,812 kg/ha) compared with the lowest (5,171 kg/ha) by rolled rye, narrow strip, and row cleaners on the planter. In 2009, cotton stand for rolled rye was higher (115,036 plants/ha) compared to non-rolled rye residue (65,894 plants/ha). In 2009, the cotton yield was substantially reduced by flooding of the experimental area. Because of the excess water, the cotton yield was lower (2,672 kg/ha) compared to 2007 and 2008 growing seasons. Soil strength measurements taken in fall 2009 showed significantly lower cone index values with rolled vs. non-rolled rye from 0 to 15-cm depth, with trends reversed after 20 cm. Cone index values at all depths, however, were below the 2-MPa threshold that indicates restrictive conditions for root growth. In all three growing seasons, the width of the tillage strip and the location of row cleaners (planter/subsoiler) did not affect cotton stand and seed cotton yield.

Current research has focused on sand-sized particles introduced to gravel beds, while the effect of silt load on sand transport has received less attention. Experiments on the effects of silt load, in concentrations 0-26,900 mg 1(-1), on sand transport were performed with a recirculating laboratory flume using three different sand bed configurations: ripples (Fr=0.24), dunes (Fr=0.34)., dunes (Fr=0.48). Three Acoustic Doppler Velocimeters were arranged to measure flow and turbulence quantities simultaneously in one vertical. Sand transport did not change in a consistent manner with increasing silt load, increasing up to 4,000 mg 1(-1) for dunes (Fr=0.48) and up to 2,000 mg 1(-1) for dunes (Fr=0.34) and then declining to near the clear water case with increasing silt concentrations. Silt addition for the ripple case caused a relatively small change in sand transport, decreasing with added silt up to approximately 2,000 mg 1(-1) and then increasing as silt went up to approximately 10,000 mg 1(-1). Dunes (Fr=0.48) decreased in length and height as silt increased, while dunes (Fr=0.34) did not show a consistent trend. A clear trend of decreasing Reynolds stress with increasing silt concentration was observed in the ripple case, with a 33% reduction in near-bed Reynolds stress caused by an 8,900 mg 1(-1) concentration of silt.

This study evaluates the effect of India's childhood vaccination program Universal Immunization Program (UIP) on the growth of children <4 years of age. Methods Regression models were estimated to examine the effect of UIP on vaccination status and children's anthropometric outcomes, as well as to test whether UIP's effect was uniform across various subpopulations of Indian children. Results UIP increased height-for-age and weight-for-age among children. This effect constituted a 22-25% reduction in the height-for-age deficit and a 15% reduction in the weight-for-age deficit of the average child. The program appears to have had no effect on other anthropometric indicators or vaccination status. UIP also led to differential changes in anthropometry and vaccination status, based on differences in wealth, maternal education and scheduled-caste status. Conclusions UIP led to improved child growth. This suggests that vaccination programs-in addition to being a major intervention for reducing child mortality-might be considered a tool for mitigating undernutrition in developing countries.

In this study, the effects of possible future anthropogenic climate change on reference evapotranspiration (ET(0)) were evaluated using the Penman-Monteith equation. The combined effect of temperature and elevated CO(2) concentrations on ET(0) was the major focus of this study. The ET(0) under the General Circulation Model (GCM) projected climate change scenarios was estimated for a location in Colorado. Multi-model ensemble climate change scenarios were generated from 112 Bias Corrected and Spatially Disaggregated (BCSD) projections from the World Climate Research Program (WCRP) archive, which cover different levels of greenhouse gas emissions. Results showed a decrease in ET(0) demand with increases in CO(2) levels, which greatly moderated the increase in ET(0) due to increasing temperature. The effect of increases in CO(2) levels up to 450 ppm offset the effect of about 1 degree C rise in temperature. Simulation results with projected climate change scenarios, without considering the effects of CO(2) levels, showed an 8.3%, 14.7% and 21.0% increase in annual ET(0) during the 2020s, 2050s, and 2080s, respectively, when simulation was carried out using an ensemble of the 112 projections. When the effect of elevated CO(2) levels was also considered in combination with projected changes in temperature, changes in annual ET(0) demand varied from -1.5% to 5.5%, -10.4% to 6.7%, and -19.7% to 6.6% during the 2020s, 2050s, and 2080s, respectively, depending on the different climate change scenarios considered and the relationship or equation used for estimating the effect of elevated CO(2) on stomatal resistance term in the Penman-Monteith equation.

However, N losses from agricultural systems have resulted in numerous deleterious environmental impacts, including a continuing increase in atmospheric nitrous oxide (N sub(2)O), a greenhouse gas (GHG) and an important catalyst of stratospheric ozone depletion. Although associated with about 7% of total US GHG emissions, agricultural systems account for 75% of total US N sub(2)O emissions. Increased productivity in the crop and livestock sectors during the past 30 to 70 years has resulted in decreased N sub(2)O emissions per unit of production, but N sub(2)O emissions from US agriculture continue to increase at a rate of approximately 0.46 teragrams of carbon dioxide equivalents per year (2002-2009). This rate is lower than that during the late 20th century. Improvements in agricultural productivity alone may be insufficaient to lead to reauced emissions; implementing strategise specifically targeted at readucing N sub(2)O emissions may therefore be necessary.

AN - 1315613889; 17718288 AB - Climate stabilization wedges are defined as strategies that contribute to greenhouse-gas (GHG) mitigation that - in aggregate - achieve a particular goal. Wedges have been proposed as a GHG mitigation framework because no single technology or economic sector can sufficiently reduce emissions to acceptable levels. To avoid the most dangerous risks of climate change, we argue that mitigation of similar to 9000 teragrams of carbon equivalents (Tg Ceq) will be required by the year 2030. We estimate that agriculture could provide wedges of 1350 to 3900 Tg Ceq under attainment of technological and human behavior mitigation potentials. Improved agricultural management can decrease nitrous oxide and methane emissions and increase carbon sequestration. Consumption of fewer livestock products along with agricultural intensification through available technologies can result in reduced emissions in both developed and developing countries. Decreasing excess protein and calorie consumption in developed countries improves personal health, while reforestation and avoided deforestation in developing countries help to maintain biodiversity. The mitigation wedges have varying economic costs but also have multiple benefits.

Here, we highlight the factors that make mitigating N sub(2)O emissions from fertilized agroecosystems such a difficult challenge, and discuss how these factors limit the effectiveness of existing practices and therefore require new technologies and fresh ideas. Modification of the rate, source, placement, and/or timing of nitrogen fertilizer application has in some cases been an effective way to reduce N sub(2)O emissions. However, the efficacy of existing approaches to reducing N sub(2)O emissions while maintaining crop yields across locations and growing seasons is uncertain because of the interaction of multiple factors that regulate several different N sub(2)O-producing processes in soil. Although these processes have been well studied, our understanding of key aspects and our ability to manage them to mitigate N sub(2)O emissions remain limited.

A current threat to the U.S. cotton industry is Oxycarenus hyalinipennis (Costa), commonly known as the cotton seed bug. Populations are found throughout most of the world except for North America, and the southeastern U.S. is believed to provide a favorable environment for its establishment. A major component in efforts to control the spread of invasive pests is the rapid and accurate identification of intercepted specimens. Unfortunately, O. hyalinipennis belongs to an incompletely characterized taxon where the assignment of species identity by simple morphological keys is often problematic. In this study, we assessed the potential of DNA barcoding to facilitate the identification of the cotton seed bug in field-collected specimens.

Biological control programs designed to mitigate the impact of these pests would be beneficial; therefore, we sought to identify and assess naturally occurring biological control agents of stink bug eggs in cotton, peanut and soybeans, three important crops and stink bug hosts in the region. Two studies were conducted utilising digital imaging of sentinel egg masses to capture enemies present and sequential imaging over time to characterise the type and amount of damage inflicted on the egg masses. The first study utilised plots of soybean, Bt cotton, non-Bt cotton and peanut. The second study focused on ant predation in cotton by excluding fire ants from half of the plots. Sentinel egg masses of the southern green stink bug were placed in all plots at weekly intervals and were photographed at placement and at intervals over 72 h. Surviving egg masses were collected and held in the laboratory to assess parasitism in the first study. Predation of eggs was high in peanut (74-86%) and soybean (39-65%), and lower in Bt (26-34%) and non-Bt (4-21%) cotton over the two years. Parasitism was low overall (0.17-19.0%). Most egg predation in cotton and peanut was attributable to fire ants, whereas long-horned grasshoppers dominated in soybean. Exclusion of fire ants in cotton significantly reduced egg mortality, indicating their predominance as mortality agents in cotton.

However, its unintentional arrival in Florida raised serious concern over its possible effect on native Opuntia biodiversity and Opuntia-based industries. Development of control tactics to mitigate the threat of this invasive pest to North America relied upon a constant supply of all life stages of this insect species. Therefore, 3 strains of C. cactorum were established in a laboratory insectary and trials were initiated to optimize rearing methods using an artificial diet. Because monophagous or oligophagous lepidopterans may be sensitive to the balance of nutrients and/or the presence of specific feeding cues and because different strains of an oligophagous lepidopteran may respond differently to various meridic diets, we compared the development and survival of 3 strains of C. cactorum on several meridic diets without host plant materials. Although C. cactorum is an oligophage within the genus Opuntia, it accepted and developed on several diets containing non-host plant ingredients, yeast, and fish meal. The source and balance of non-host nutrients significantly affected all reproductive parameters of C. cactorum. The best performance of C. cactorum was on diets that contained white kidney beans, brewer's yeast, wheat germ and/or soybeans.

Reducing the time to detect HPAI infection can reduce the risk of disease transmission to other flocks. The timeliness of different types of detection triggers could be dependent on clinical signs that are first observed in a flock, signs that might vary due to HPAI virus strain characteristics. We developed a stochastic disease transmission model to evaluate how transmission characteristics of various HPAI strains might effect the relative importance of increased mortality, drop in egg production, or daily real-time reverse transcriptase (RRT)-PCR testing, toward detecting HPAI infection in a commercial table-egg layer flock. On average, daily RRT-PCR testing resulted in the shortest time to detection (from 3.5 to 6.1 days) depending on the HPAI virus strain and was less variable over a range of transmission parameters compared with other triggers evaluated. Our results indicate that a trigger to detect a drop in egg production would be useful for HPAI virus strains with long infectious periods (6-8 days) and including an egg-drop detection trigger in emergency response plans would lead to earlier and consistent reporting in some cases. We discuss implications for outbreak control and risk of HPAI spread attributed to different HPAI strain characteristics where an increase in mortality or a drop in egg production or both would be among the first clinical signs observed in an infected flock.

Overwintering adults were collected near Stoneville, MS from blooming henbit, Lamium amplexicaule L., and from plant debris during December and January and dissected to determine their reproductive status. Averaged over four winters, male and female tarnished plant bugs collected from henbit terminated diapause at a significantly higher rate than males and females from plant debris during each week of December and the first week of January. Both sexes in each habitat were nearly all reproductive by the end of January. Adults overwintering in plant debris terminated diapause during January in the absence of a food stimulus in all 5 yr studied. This emergence was thought to be controlled by an internal clock. Laboratory and field studies showed that emergence from diapause could be influenced by food, sex, and temperature. Adults overwintering on a suitable food source, blooming henbit, terminated diapause during December in the 4 yr studied, and males terminated diapause more rapidly than females. Food quality was important in emergence from diapause, and females on blooming henbit terminated diapause at a significantly higher rate than females on nonblooming mustard, Brassica juncea (L.) Cosson. Laboratory tests showed that diapausing adults reared in the laboratory and held at a diapause-maintaining photoperiod of 10:14 (L:D) h could be terminated from diapause by using food and temperature stimuli. The lower thermal threshold for development to reproductive adults was found to be near 10 degree C. The ability of diapausing adults to respond to food and temperature stimuli in December can enable tarnished plant bugs to take advantage of warm winters and winter hosts to produce a new generation earlier.

The first was conducted on replicated 4.04-ha plots in lodgepole pine stands (California, 2008) and the second on 0.81-ha plots in whitebark pine stands (Washington, 2010). In both studies, D. ponderosae population levels were moderate to severe. The treatments were 1) push-only (D. ponderosae antiaggregant semiochemicals alone); 2) push-pull (D. ponderosae antiaggregants plus perimeter traps placed at regular intervals, baited with four-component D.ponderosae aggregation pheromone); and 3) untreated controls. We installed monitoring traps baited with two-component D. ponderosae lures inside each plot to assess effect of treatments on beetle flight. In California, fewer beetles were collected in push-pull treated plots than in control plots, but push-only did not have a significant effect on trap catch. Both treatments significantly reduced the rate of mass and strip attacks by D.ponderosae, but the difference in attack rates between push-pull and push-only was not significant. In Washington, both push-pull and push-only treatments significantly reduced numbers of beetles caught in traps. Differences between attack rates in treated and control plots in Washington were not significant, but the push-only treatment reduced attack rates by 30% compared with both the control and push-pull treatment. We conclude that, at these spatial scales and beetle densities, push-only may be preferable for mitigating D.ponderosae attack because it is much less expensive, simpler, and adding trap-out does not appear to improve efficacy.

Thirty samples from the litter/duff (LD) and the top 5 cm of the mineral soil (MS) were collected from five 5-ha burn units (6 plots per experimental unit) before and immediately after low-intensity prescribed fires, where maximum fire temperatures varied from <79 to 316 degree C. A split-plot ANOVA and multi-response permutation procedures (MRBP) were utilized to assess the effects of burn treatment (pre- or post-fire) and seed bank layer (LD and MS) on the diversity and density of the buried seed bank. An average of 471 emergents/m2 was observed in the buried seed bank comprising 133 identifiable taxa. No differences in total seed-bank density, Shannon-Weiner's diversity index (H') or overall species composition between pre- and post-fire sampling or between the LD and MS layers were observed. Species richness (S) of the seed bank, however, was slightly greater pre-fire than post-fire, regardless of layer. Similarity, as defined by Soerenson's index, of species common to the seed bank and aboveground forest understory was low, with a slight increase in Soerenson's index observed during post-fire sampling of the seed bank and aboveground vegetation. Although we observed only negligible effects of a once-applied, low-intensity prescribed fire on the buried seed bank, the effects of a low-intensity prescribed fire management regime-one that involves repeated low intensity burns-on the buried seed bank are unknown and should be a focus of future studies across mixed-oak forests in the eastern US.

(Hymenoptera: Siricidae) was detected in New York State and later found to be established over a larger area, including parts of southeastern Canada and the northeastern United States. A key component of S. noctilio detection and management plans in other parts of the world where S. noctilio has become established are chemically girdled trap trees. Trap tree usage in North America is confounded by the presence of diverse communities of organisms that inhabit dead and dying trees. We trapped a portion of the arboreal insect community arriving at Pinus resinosa Ait. and Pinus sylvestris L., trap trees girdled 3 mo before (April), one month before (June), and at S. noctilio flight (July) in central New York. Multiple-funnel traps attached to trap trees captured 30,031 individuals from 109 species of Scolytinae, Cerambycidae, and Siricidae. Ipspini (Say) and Ips grandicollis (Eichhoff) accounted for almost 50% of the scolytines captured at trap trees and were present on all girdling dates. Significantly more scolytines and cerambycids were captured on P. sylvestris compared with P. resinosa, but species richness of captured insects did not differ between the two trees. More total and conifer-inhabiting scolytines and cerambycids were captured in traps on trees girdled in April and June and higher observed species richness was found on trees girdled in April and controls. Results from this study suggest a large community of arboreal insects and associated organisms are attracted to chemically girdled trap trees and likely interact with S. noctilio.

Infested citrus orchards act as a source of vectors to adjacent vineyards where X. fastidiosa causes Pierce's disease. An analysis of the pattern and rate of movement of H. vitripennis and its egg parasitoid, Gonatocerus ashmeadi Girault, was conducted in a citrus orchard by using a protein mark-capture technique to quantify movement and net dispersal rates in the experimental areas. Treatments included irrigation at 100% of the crop evapotranspiration rate (ETc), 80, and 60% ETc. Sex-specific net dispersal rates showed that H. vitripennis males and females moved consistently and contributed equally to the level of population change within treated areas. Trees irrigated at 60% ETc were the least preferred by H. vitripennis. Among all protein-marked individuals captured in the 60% ETc treatment, approximately 75 and 88% in 2005 and 2006, respectively, were inflow individuals. Movement toward less preferable plants indicates that in agricultural landscapes dominated by perennial monocultures, there is a random component to H. vitripennis movement, which may result from the inability of H. vitripennis to use plant visual cues, olfactory cues, or both to make well-informed long-range decisions. The 80% ETc areas were a significant source of adult H. vitripennis and G. ashmeadi compared with the other treatments. Colonization rates by parasitoids were synchronized with the spatiotemporal distribution of H. vitripennis eggs. Results suggest that H. vitripennis movement from citrus into adjacent vineyards could be a result of random dispersal rather than oriented movement in response to host-plant characteristics.

After several days of feeding, the flour becomes conditioned by the beetles, which can affect rates of cannibalism. Flour conditioning is caused by an accumulation of feces, pheromones, and ethylquinone, which is a repellent produced by the beetles. We determined the effect of five different levels of flour conditioning on cannibalism of red flour beetle eggs and pupae by adult and larval stages. Larvae had the highest rates of egg cannibalism (12 eggs eaten over the 4-d period) followed by female adults (seven eggs consumed). Adult males had the lowest rates of cannibalism with only two eggs consumed. Cannibalism of eggs by females was correlated negatively with the level of flour conditioning. There was no effect of flour conditioning on egg or pupal cannibalism by larvae or adult males. Cannibalism by adult females may decrease as the level of flour conditioning increases because females may spend less time tunneling in highly conditioned flour and more time trying to disperse to other areas that are better for oviposition.

Effective semiochemical-based detection and control programs for X.glabratus will require an understanding of the chemical ecology and host-seeking behaviors of this new invasive pest. This study 1) presents an electroantennography (EAG) method developed for assessment of olfactory responses in ambrosia beetles; 2) uses that new method to quantify EAG responses of X.glabratus, X. affinis, and X. ferrugineus to volatiles from three host-based attractants: manuka oil (essential oil extract from Leptospermum scoparium Forst. & Forst.), phoebe oil (extract from Phoebe porosa Mex.), and wood from silkbay (Persea humilis Nash); and 3) documents temporal differences in host-seeking flight of the sympatric Xyleborus species. Field observations revealed that X.glabratus engages in flight several hours earlier than X.affinis and X.ferrugineus, providing a window for selective capture of the target pest species. In EAG analyses with X.glabratus, antennal response to phoebe oil was equivalent to response to host Persea wood, but EAG response elicited with manuka oil was significantly less. In comparative studies, EAG response of X.glabratus was significantly higher than response of either X.affinis or X.ferrugineus to all three host-based substrates. Future research will use this EAG method to measure olfactory responses to synthetic terpenoids, facilitating identification of the specific kairomones used by X.glabratus for host location.

They can also affect the strength of each other's impact by modifying traits in their shared host, producing super- or sub-additive outcomes. This phenomenon is especially relevant to biological control of invasive plants because most invaders are attacked by multiple agents. Unfortunately, complex interactions among agents are rarely studied. We used structural equation modeling (SEM) to quantify the effect of two biocontrol agents and generalist pollinators on the invasive weed Centaurea solstitialis, and to identify and quantify the direct and indirect interaction pathways among them. The weevil Eustenopus villosus is both a bud herbivore and a predispersal seed predator; the fly Chaetorellia succinea is also a predispersal seed predator; Apis mellifera is the primary pollinator. We conducted this work at three sites spanning the longitudinal range of C. solstitialis in California (USA) from the coast to the Sierra Nevada Mountains. SEM revealed that bud herbivory had the largest total effect on the weed's fecundity. The direct effect of bud herbivory on final seed set was 2-4 times larger in magnitude than the direct effect of seed predation by both agents combined. SEM also revealed important indirect interactions; by reducing the number of inflorescences plants produced, bud herbivory indirectly reduced the plant's attractiveness to ovipositing seed predators. This indirect, positive pathway reduced bud herbivory's direct negative effect by 11-25%. In the same way, bud herbivory also reduced pollinator visitation, although the magnitude of this pathway was relatively small. E. villosus oviposition deterred C. succinea oviposition, which is unfortunate because C. succinea is the more voracious of the seed predators. Finally, C. succinea oviposition indirectly deterred pollinator visitation, thereby enhancing its net effect on the plant. This study demonstrates the powerful insights that can be gained from the SEM approach in understanding the multiple direct and indirect interactions among agents and pollinators and their effects on an invasive weed. Such an approach may improve our ability to manage weeds with biocontrol agents by identifying pathways that could be exploited by future agents and minimizing the possibility of interference with established agents.

ER - TY - JOUR T1 - Quantifying opportunities and threats: examining the Canada-EU trade negotiations AN - 1272074344; 4383999 AB - This study examines the impacts of a Canadian-EU preferential trade agreement. A carefully designed contemporary baseline scenario and additional HS6 tariff offer data are incorporated to establish the degree of ambition of the negotiations whilst assessing the sectoral trade opportunities and threats facing both partners. Initial tariff offer real income gains are estimated at 76% of full liberalisation in both regions, rising to 91% (Canada) and 84% (EU) under the second tariff offer. Given higher levels of applied tariff protection, potentially significant impacts are measured in dairy, meat and wheat sectors. Trade diversion losses on third countries are negligible.

CLS management practices include the application of the sterol demethylation inhibitor (DMI) fungicides tetraconazole, difenoconazole, and prothioconazole. Evaluating resistance to DMIs is a major focus for CLS fungicide resistance management. Isolates were collected in 1997 and 1998 (baseline sensitivity to tetraconazole, prothioconazole, or difenoconazole) and 2007 through 2010 from the major sugar-beet-growing regions of Minnesota and North Dakota and assessed for in vitro sensitivity to two or three DMI fungicides. Most (47%) isolates collected in 1997-98 exhibited 50% effective concentration (EC sub(50)) values for tetraconazole of 0.11 mu g mh super(-1) increased from 2008 to 2010. In contrast, the frequency of isolates with EC sub(50) values for prothioconazole of >1.0 mu g ml super(-1) has been decreasing since 2007. Annual median difenoconazole EC sub(50) values appears to be stable, although annual mean EC sub(50) values generally have been increasing for this fungicide. Although EC sub(50) values are important for gauging fungicide sensitivity trends, a rigorous comparison of the relationship between in vitro EC sub(50) values and loss of fungicide efficacy in planta has not been conducted for C. beticola. To explore this, 12 isolates exhibiting a wide range of tetraconazole EC sub(50) values were inoculated to sugar beet but no tetraconazole was applied. No relationship was found between isolate EC sub(50) value and disease severity. To assess whether EC sub(50) values are related to fungicide efficacy in planta, sugar beet plants were sprayed with various dilutions of Eminent, the commercial formulation of tetraconazole, and subsequently inoculated with isolates that exhibited very low, medium, or high tetraconazole EC sub(50) values. The high EC sub(50) isolate caused significantly more disease than isolates with medium or very low EC sub(50) values at the field application rate and most reduced rates. Because in vitro sensitivity testing is typically carried out with the active ingredient of the commercial fungicide, we investigated whether loss of disease control was the same for tetraconazole as for the commercial product Eminent. The high EC sub(50) isolate caused more disease on plants treated with tetraconazole than Eminent but disease severity was not different between plants inoculated with the very low EC sub(50) isolate.

Economic losses can be up to S222 per hectare (2). Despite prolonged effort, no promising insects have been found as agents of biological control of H. caespitosum. This has led to a greater emphasis on seeking plant pathogens such as rusts and smuts as potential biological control agents. Searches for plant pathogens have included Europe, which contains a portion of the native range of the weed. In the small stands of H. caespitosum that occur in northern France, plants were found with chlorosis and significant stunting. Typically, 10 to 30% of plants in affected stands exhibited such symptoms. Excavation and examination of roots revealed discrete necrotic lesions along the length of roots and decayed root tips, roughly resembling symptoms of corky root. Ten roots with these symptoms were thoroughly washed, cut into similar to 0.25- to 0.5-cm-long pieces and plated on potato dextrose agar (PDA) and acidified PDA. On these media, colonies were light-salmon-beige, woolly, zonate, with older mycelium sparser with the dense occurrence of dark, hemispherical conidiomata. The conidiomata exuded pink spore masses. The spores were hyaline and falcate with acute apices, 6.2 x 1.6 mu m (n = 200). These traits match published descriptions of Pilidium concavum, described as a pathogen of numerous plants usually causing leaf spots and stem necrosis (3). To corroborate this identification, the internal transcribed spacer region of rDNA was amplified by PCR using primers ITS1 and ITS4 and sequenced. BLAST analysis of the 575-bp fragment (GenBank Accession No. JX047867) showed 100% homology with the sequences of six isolates of P. concavum in GenBank, including Accession No. AY487094. To confirm pathogenicity, five each of 30-day-old H. caespitosum plants were either sprayed with, or their roots soaked for 1 hr in a 1 x 10 super(6) per ml suspension of conidia prepared from 10-day-old cultures of the fungus grown on V8 agar. An equal number of control plants were either sprayed with sterile distilled water (SDW) or their roots were soaked for an hour in SDW. To plant soaked roots, a hole was made in the pre-moistened pasteurized potting mix in each pot and inoculum or SDW was poured around them before they were covered with soil. The experiments were repeated twice. Following leaf inoculations, plants were covered with a plastic bag and placed in the greenhouse in partial shade at 20 to 25 degree C for 72 to 96 h. Sprayed plants were then uncovered and assessed for the appearance of lesions over the next 7 to 10 days. No foliar symptoms occurred. Plants inoculated by soaking roots showed chlorosis and stunting by 4 months post-inoculation. P. concavum was isolated from root lesions on all inoculated, symptomatic plants, confirming Koch's postulates. Although reported to cause root deterioration of strawberry (4), to our knowledge, this the first report of a root disease of H. caespitosum caused by P. concavum.

Apples harvested in 2010 were stored in a controlled atmosphere at a commercial Pennsylvania apple packing and storage facility, and were examined for occurrence of decay in May 2011. Several decayed apples from different cultivars, exhibiting blue mold symptoms with a sporulating fungus were collected. One isolate recovered from a decayed 'Golden Delicious' apple fruit was identified as P. carneum Frisvad. Genomic DNA was isolated, 800 bp of the 3' end of the beta -tubulin locus was amplified using gene specific primers and sequenced (4). The recovered nucleotide sequence (GenBank Accession No. JX127312) indicated 99% sequence identity with P. carneum strain IBT 3472 (GenBank Accession No. JF302650) (3). The P. carneum colonies strongly sporulated and had a blue green color on potato dextrose agar (PDA), Czapek yeast autolysate agar (CYA), malt extract agar (MEA), and yeast extract sucrose agar (YES) media at 25 degree C after 7 days. The colonies also had a beige color on plate reverse on CYA and YES media. The species tested positive for the production of alkaloids, as indicated by a violet reaction for the Ehrlich test, and grew on CYA at 30 degree C and on Czapek with 1,000 ppm propionic acid agar at 25 degree C; all of which are diagnostic characters of this species (2). The conidiophores were hyaline and tetraverticillate with a finely rough stipe. Conida were produced in long columns, blue green, globose, and averaged 2.9 mu m in diameter. To prove pathogenicity, Koch's postulates were conducted using 20 'Golden Delicious' apple fruits. Fruits were washed, surface sterilized with 70% ethanol, and placed onto fruit trays. Using a nail, 3-mm wounds were created and inoculated with 50 mu l of a 10 super(6)/ml conidial suspension or water only as a negative control. The fruit trays were placed into boxes and were stored in the laboratory at 20 degree C for 7 days. The inoculated fruit developed soft watery lesions, with hard defined edges 37 plus or minus 4 mm in diameter. The sporulating fungus was reisolated from infected tissue of all conidia inoculated apples and confirmed to be P. carneum by polymerase chain reaction (PCR) using the beta -tubulin locus as described. Water inoculated control apples were symptomless. Originally grouped with P. roqueforti, P. carneum was reclassified in 1996 as a separate species (1). P. carneum is typically associated with meat products, beverages, and bread spoilage and produces patulin, which is not produced by P. roqueforti (1,2). Our isolate of P. carneum was susceptible to the thiabendazole (TBZ) fungicide at 250 ppm, which is below the recommended labeled application rate of 600 ppm. The susceptibility to TBZ suggests that this P. carneum isolate has been recently introduced because resistance to TBZ has evolved rapidly in P. expansum (4). To the best of our knowledge, P. carneum has not previously been described on apple, and this is the first report of P. carneum causing postharvest decay on apple fruits obtained from storage in Pennsylvania.

With appropriately chosen targets, the RNAi pathway has also been exploited for insect control, typically through oral delivery of dsRNA. Adapting current methods to deliver foreign compounds, such as amino acids and pesticides, to mosquitoes through sucrose solutions, we tested whether such an approach could be used in the yellow fever mosquito, Aedes aegypti. Using a non-specific dsRNA construct, we found that adult Ae. aegypti ingested dsRNA through this method and that the ingested dsRNA can be recovered from the mosquitoes post-feeding. Through the feeding of a species-specific dsRNA construct against vacuolar ATPase, subunit A, we found that significant gene knockdown could be achieved at 12, 24 and 48h post-feeding.

Options to control the insect depend mostly on and are limited to the use of insecticide. Data are needed to determine the toxicity of currently available insecticides to brown stink bug and develop baseline mortality to assess resistance to insecticides in Central Texas. Using a glass-vial bioassay, the LC10 and LC50 values for selected commercially formulated insecticides, the technicalgrade active ingredients, and mixtures of active ingredients were determined for brown stink bugs captured in black-light traps near farmlands in Caldwell County, Texas. The LC10 and LC50 values showed the mixtures of technical-grade insecticides were 37- to 526- and 58- to 384-fold, respectively, more toxic to brown stink bug compared to the respective commercial formulations. The toxicological response of the technical-grade active ingredients relative to the mixtures varied from synergistic to antagonistic. Baseline data for brown stink bug mortality are useful for comparison with local populations should suspicion of tolerance to the insecticides develop in Central Texas. Data demonstrate lack of potentiation of the mixtures, probably because of absence of additivity or synergism in the composition of active and inert ingredients in the formulations or decreased composition of each component in the formulated mixtures.

Resin response of fire-injured northern Rocky Mountain ponderosa pine (Pinus ponderosa Douglas ex P. Lawson & C. Lawson) and specific injuries that contribute to increased bark beetle attack susceptibility and brood production are unknown. We monitored ponderosa pine mortality and resin flow and bark beetle colonization and reproduction following a prescribed fire in Idaho and a wildfire in Montana. The level of fire-caused tree injury differed between the two sites, and the level of tree injury most susceptible to bark beetle attack and colonization also differed. Strip-attacked trees alive 3 years post-fire had lower levels of bole and crown injury than trees mass attacked and killed by bark beetles, suggesting that fire-injured trees were less well defended. Brood production of western pine beetle (Dendroctonus brevicomis LeConte) did not differ between fire-injured and uninjured trees, although mountain pine beetle (Dendroctonus ponderosae Hopkins) brood production was low in both tree types, potentially due to competition with faster developing bark beetle species that also colonized trees. Despite a large number of live trees remaining at both sites, bark beetle response to fire-injured trees pulsed and receded within 2 years post-fire, potentially due to a limited number of trees that could be easily colonized.Original Abstract: Les scolytes peuvent tuer beaucoup d'arbres qui pourraient autrement survivre aux blessures causees par le feu. La production de resine chez les pins ponderosa (Pinus ponderosa Douglas ex P. Lawson & C. Lawson) dans le nord des montagnes Rocheuses en reaction aux blessures causees par le feu ainsi que les blessures specifiques qui contribuent a l'augmentation de la susceptibilite aux attaques des scolytes et a la production de nouvelles generations d'insectes n'ont pas ete etudiees. Nous avons suivi la mortalite et l'ecoulement de resine chez le pin ponderosa, ainsi que la colonisation et la reproduction des scolytes a la suite d'un brulage dirige en Idaho et d'un feu de foret au Montana. La quantite de blessures causees par le feu etait differente dans les deux stations et la quantite de blessures sur arbres les plus susceptibles d'etre attaques et colonises par les scolytes etait egalement differente. Les arbres qui avaient subi une attaque localisee et qui etaient vivants 3 ans apres le passage du feu avaient moins de blessures au tronc et dans la cime que les arbres qui avaient subi une attaque massive et avaient ete tues par les scolytes; ce qui implique que les arbres blesses par le feu s'etaient moins bien defendus. La production de nouvelles generations de dendroctone occidental du pin (Dendroctonus brevicomis LeConte) n'etait pas differente que les arbres aient ete blesses ou non par le feu, mais la production de nouvelles generations de dendroctone du pin ponderosa (Dendroctonus ponderosae Hopkins) etait faible chez les deux types d'arbre, possiblement a cause de la competition d'especes de scolyte dont la croissance etait plus rapide et qui colonisaient aussi les arbres. Malgre le grand nombre d'arbres vivants encore presents dans les deux stations, la reponse des scolytes aux arbres blesses par le feu a bondi et s'est resorbee en moins de 2 ans apres le feu, possiblement a cause du nombre restreint d'arbres qui pouvaient facilement etre colonises.

For example, in many arid and semi-arid regions, parcels of irrigated cropland are juxtaposed with hot, dry surfaces. Contrasting surface conditions can result in the advection of warm dry air over an irrigated crop surface where it increases the water vapor deficit and, thereby, atmospheric demand. If sufficient water is available, this can significantly enhance evaporative water loss from the irrigated field. The scale and frequency of turbulent eddies over an irrigated surface during periods of strong advection is not fully understood. High frequency (20Hz) data were acquired over irrigated cotton, wheat stubble, and rangeland fields during the 2008 growing season as part of the Bushland Evapotranspiration and Agricultural Remote Sensing Experiment (BEAREX08). Spectral analysis of momentum and scalar quantities including heat and water vapor revealed low frequency features in the turbulence structure due to the penetration of the surface boundary layer by large-scale eddies during periods of unusually strong advection. Wavelet analysis was applied to assess specific events contributing to the spatial and temporal structure of turbulent flux eddies. The analysis showed that low frequency contributions were linked to both local and regional scale advective processes. These results clearly point to a need to better understand surface energy balance exchange for heterogeneous surfaces in arid and semi-arid regions under conditions of strong local and regional advection.

This Bushland Evapotranspiration and Agricultural Remote sensing EXperiment 2008 (BEAREX08) involved determination of micrometeorological fluxes (surface energy balance) in four weighing lysimeter fields (each 4.7ha) containing irrigated and dryland cotton and in nearby bare soil, wheat stubble and rangeland fields using nine eddy covariance stations, three large aperture scintillometers, and three Bowen ratio systems. In coordination with satellite overpasses, flux and remote sensing aircraft flew transects over the surrounding fields and region encompassing an area contributing fluxes from 10 to 30km upwind of the USDA-ARS lysimeter site. Tethered balloon soundings were conducted over the irrigated fields to investigate the effect of advection on local boundary layer development. Local ET was measured using four large weighing lysimeters, while field scale estimates were made by soil water balance with a network of neutron probe profile water sites and from the stationary flux systems. Aircraft and satellite imagery were obtained at different spatial and temporal resolutions. Plot-scale experiments dealt with row orientation and crop height effects on spatial and temporal patterns of soil surface temperature, soil water content, soil heat flux, evaporation from soil in the interrow, plant transpiration and canopy and soil radiation fluxes. The BEAREX08 field experiment was unique in its assessment of ET fluxes over a broad range in spatial scales; comparing direct and indirect methods at local scales with remote sensing based methods and models using aircraft and satellite imagery at local to regional scales, and comparing mass balance-based ET ground truth with eddy covariance and remote sensing-based methods.

The change in heat storage is based on the soil temperature change in the layer over the time period and an estimate of the soil thermal heat capacity that is based on soil water content, bulk density and organic matter content. One- or multiple-layer corrections using some measure of mean soil temperature over the layer depth are common; and in some cases the soil water content has been determined, although rarely. Several problems with the heat flux plate method limit the accuracy of soil heat flux values. An alternative method is presented and this flux gradient method is compared with soil heat flux plate measurements. The method is based on periodic (e.g., half-hourly) water content and temperature sensing at multiple depths within the soil profile and a solution of the Fourier heat flux equation. A Fourier sine series is fit to the temperature at each depth and the temperature at the next depth below is simulated with a sine series solution of the differential heat flux equation using successive approximation of the best fit based on changing the thermal diffusivity value. The best fit thermal diffusivity value is converted to a thermal conductivity value using the soil heat capacity, which is based on the measured water content and bulk density. A statistical analysis of the many data resulting from repeated application of this method is applied to describe the thermal conductivity as a function of water content and bulk density. The soil heat flux between each pair of temperature measurement depths is computed using the thermal conductivity function and measured water contents. The thermal gradient method of heat flux calculation compared well to values determined using heat flux plates and calorimetric correction to the soil surface; and it provided better representation of the surface spatiotemporal variation of heat flux and more accurate heat flux values. The overall method resulted in additional important knowledge including the water content dynamics in the near-surface soil profile and a soil-specific function relating thermal conductivity to soil water content and bulk density.

With regards to in situ [thetas] probes, it is sometimes assumed that a single local measurement can represent the larger domain, mostly for practical reasons. But there is a substantial amount of variability in [thetas] at the field scale. As part of the Bushland Evapotranspiration and Agricultural Remote Sensing Experiment 2008 (BEAREX08), a high-density sensor network and intensive observational periods were developed to fully describe the [thetas] conditions at the surface on the field scale, in support of the hydro-meteorological measurements being collected. A total of 20 [thetas] stations were distributed over an irrigated and a non-irrigated field ( similar to 10ha each) and high-density ( similar to every 5cm) transects were measured for a high-detailed record. The network was able to provide large scale estimates of [thetas] with an accuracy (root mean square error, RMSE) of 0.035m3/m3. The network was temporally stable with the exception being immediately during and after irrigation events. Irrigation caused significant increases in coefficients of variation due to the length of time (8-12h) necessary to irrigate the entire field. The spatial distribution of surface [thetas] was significantly affected by the row structure of the cotton plants, which was North-South in the field where transect measurements were made with a row spacing of 76cm. At scales <35cm (approximately half the row spacing), the distribution was correlated in the East-West direction. For scales larger than 35cm in the East-West direction the correlation decreased, but was still present. In the North-South direction this discontinuity was not present, and [thetas] followed a power law distribution.

Using data collected primarily within a pair of irrigated cotton fields as a part of the 2008 Bushland Evapotranspiration and Remote Sensing Experiment (BEAREX08), flux measurements collected with two commonly-used methods, eddy covariance (EC) and lysimetry (LY), were compared and substantial differences were found. Daytime mean differences in the flux measurements from the two techniques could be in excess of 200Wm-2 under strongly advective conditions. Three causes for this disparity were found: (i) the failure of the eddy covariance systems to fully balance the surface energy budget, (ii) flux divergence due to the local advection of warm, dry air over the irrigated cotton fields, and (iii) the failure of lysimeters to accurately represent the surface properties of the cotton fields as a whole. Regardless of the underlying cause, the discrepancy among the flux measurements underscores the difficulty in collecting these measurements under strongly advective conditions. It also raises awareness of the uncertainty associated with in situ micrometeorological measurements and the need for caution when using such data for model validation or as observational evidence to definitively support or refute scientific hypotheses.

AN - 1257740422; 17425819 AB - Weighing lysimeters and neutron probes (NP) are both used to determine the change in soil water storage needed to solve for evapotranspiration (ET) using the soil water balance equation. We compared irrigated cotton ET determined using two large (332.4-m deep) weighing lysimeters and eight NP soil water profiles located outside the lysimeters in cotton fields during the BEAREX08 field campaign (see [16] Evett et al., 2012). The objectives were to (i) determine if lysimeter-based ET fluxes were representative of those from the fields, designated NE and SE, in which the lysimeters were centered, and (ii) investigate different methods of computing the soil water balance using NP data. Field fluxes were determined from the soil water balance using neutron probe measurements of change in profile water content storage. Fluxes of ET from the SE lysimeter were representative of those from the field throughout the season and can be used with reasonable certainty for comparisons of ET fluxes and energy balance closure derived from Bowen ratio (BR) and eddy covariance (EC) measurements whose footprints lay in the SE field. Comparisons of ET fluxes from EC and BR systems to those from the NE lysimeter should consider that NE lysimeter fluxes were up to 18% larger than those from the NE field during the period of rapid vegetative growth. This was due to plants on the lysimeter having greater height and width than those in the field. Nevertheless, the data from this and companion studies documents substantial underestimation of crop ET by EC stations under the conditions of BEAREX08. Comparison of zero flux plane (ZFP) and simple soil water balance methods of calculating ET from NP data showed them to be equivalent in this study; and for the ZFP method, the depth of the control volume should be determined by the depth at which the hydraulic gradient reverses, not by the depth of calculated minimum flux. If supported by a sufficiently dense and widespread network of deep soil water balance based estimates of ET in the surrounding patch and by ancillary measurements of crop stand and growth within the lysimeter and in the surrounding patch, a weighing lysimeter can provide accurate ET ground truth for comparisons with ET estimated using flux stations or ET calculated using satellite imagery. It must be emphasized that the water balance measurements must include soil profile water content measurements to well below (e.g., 0.5 to 1m below) the root zone in order to close the water balance.

For operational applications at large scales, such local information is not routinely available. In addition, the uncertainty in LST estimates can be several degrees due to sensor calibration issues, atmospheric effects and spatial variations in surface emissivity. Time differencing techniques using multi-temporal thermal remote sensing observations have been developed to reduce errors associated with deriving the surface-air temperature gradient, particularly in complex landscapes. The Dual-Temperature-Difference (DTD) method addresses these issues by utilizing the Two-Source Energy Balance (TSEB) model of Norman et al. (1995) [1], and is a relatively simple scheme requiring meteorological input from standard synoptic weather station networks or mesoscale modeling. A comparison of the TSEB and DTD schemes is performed using LST and flux observations from eddy covariance (EC) flux towers and large weighing lysimeters (LYs) in irrigated cotton fields collected during BEAREX08, a large-scale field experiment conducted in the semi-arid climate of the Texas High Plains as described by Evett et al. (2012) [2]. Model output of the energy fluxes (i.e., net radiation, soil heat flux, sensible and latent heat flux) generated with DTD and TSEB using local and remote meteorological observations are compared with EC and LY observations. The DTD method is found to be significantly more robust in flux estimation compared to the TSEB using the remote meteorological observations. However, discrepancies between model and measured fluxes are also found to be significantly affected by the local inputs of LST and vegetation cover and the representativeness of the remote sensing observations with the local flux measurement footprint.

The TSEB requires soil (TS) and canopy (TC) surface temperatures to solve the energy budgets of these layers separately. Operationally, usually only composite surface temperature (TR) measurements are available at a single view angle. For surfaces with nonrandom spatial distribution of vegetation such as row crops, TR often includes both soil and vegetation, which may have vastly different temperatures. Therefore, TS and TC must be derived from a single TR measurement using simple linear mixing, where an initial estimate of TC is calculated, and the temperature - resistance network is solved iteratively until energy balance closure is reached. Two versions of the TSEB were evaluated, where a single TR measurement was used (TSEB-TR) and separate measurements of TS and TC were used (TSEB-TC-TS). All surface temperatures (TS, TC, and TR) were measured by stationary infrared thermometers that viewed an irrigated cotton (Gossypium hirsutum L.) crop. The TSEB-TR version used a Penman-Monteith approximation for TC, rather than the Priestley-Taylor-based formulation used in the original TSEB version, because this has been found to result in more accurate partitioning of E and T under conditions of strong advection. Calculations of E, T, and ET by both model versions were compared with measurements using microlysimeters, sap flow gauges, and large monolythic weighing lysimeters, respectively. The TSEB-TR version resulted in similar overall agreement with the TSEB-TC-TS version for calculated and measured E (RMSE = 0.7mmd-1) and better overall agreement for T (RMSE = 0.9 vs. 1.9mmd-1), and ET (RMSE = 0.6 vs. 1.1mmd-1). The TSEB-TC-TS version calculated daily ET up to 1.6mmd-1 (15%) less early in the season and up to 2.0mmd-1 (44%) greater later in the season compared with lysimeter measurements. The TSEB-TR also calculated larger ET later in the season but only up to1.4mmd-1 (20%). ET underestimates by the TSEB-TC-TS version may have been related to limitations in measuring TC early in the season when the canopy was sparse. ET overestimates later in the season by both versions may have been related to a greater proportion of non-transpiring canopy elements (flowers, bolls, and senesced leaves) being out of the TC and TR measurement view.

A novobiocin-resistant strain AH11NOVO was obtained from a virulent Aer. hydrophila strain AH11P through selection of resistance to novobiocin. AH11NOVO was found to be avirulent to channel catfish (Ictalurus punctatus), whereas AH11P was virulent. When AH11NOVO vaccinated channel catfish were challenged with AH11P at 14 days postvaccination, relative per cent of survival of vaccinated fish was 100%. The cell proliferation rate of AH11NOVO was found to be significantly (P < 0.05) less than that of AH11P. In vitro motility assay revealed that AH11NOVO was nonmotile, whereas AH11P was motile. AH11NOVO had significantly (P < 0.05) lower in vitro chemotactic response to catfish mucus than that of AH11P. Although the ability of AH11NOVO to attach catfish gill cells was similar to that of AH11P, the ability of AH11NOVO to invade catfish gill cells was significantly (P < 0.05) lower than that of AH11P. The novobiocin-resistant AH11NOVO is attenuated and different from its parent AH11P in pathogenicity. The significantly lower chemotactic response and invasion ability of AH11NOVO compared with that of its virulent parent strain AH11P might shed light on the pathogenesis of Aer. hydrophila.

Effects of changes in flow and flow regime on salmonids are therefore highly stage-specific. Successful management requires consideration of stage-specific influences and integration of these effects over the entire life history to predict ultimate impacts on abundance and population viability. The state of science regarding stage-specific influences of flow regime on juvenile salmonids and their habitats, referring specifically to fundamental attributes of natural regimes and to characteristic alterations of these regimes associated with water management, is reviewed. It appears that a key consideration in integrating the stage-specific impacts of flow is the extent to which flow-related losses or gains early in ontogeny can be compensated by increased growth or survival later in juvenile life history. Further, fundamental interactions between flow and water temperature must be incorporated into the robust models ultimately required for science-based management. In the absence of such models and data, the current state of science may be sufficient to target specific aspects of flow regimes that are critical to multiple life-history stages, which can then serve as a basis for interim flow prescriptions and subsequent adaptive management.

However, household energy security has been largely ignored even though low-income households spend almost equal income shares on food and energy. This paper uses Rasch models and household responses to energy security questions in the 2005 Residential Energy Consumption Survey to generate an energy insecurity index that is consistent with those found in the food insecurity literature. The analysis yields several important findings for the generation of policy relevant household energy insecurity indexes. Questions that indicate reduction of basic expenditures, such as food, clothing, and shelter, are easiest for households to affirm implying low exposure to energy insecurity. Conversely, questions that concern households leaving the residence due to extreme temperatures consistently imply high exposure to energy insecurity. Households that score in the top decile of the energy insecurity index are more likely to be headed by single-females, be younger, and have a Black household head. Rasch models also identify flaws within survey. Particularly, the scope of the questions is quite broad and a refinement of the survey questions to focus on specific attributes of energy insecurity would likely improve future energy security indexes.

AN - 1178701300; 23042183 AB - Trichothecenes are sesquiterpenoid toxins produced by Fusarium species. Since these mycotoxins are very stable, there is interest in microbial transformations that can remove toxins from contaminated grain or cereal products. Twenty-three yeast species assigned to the Trichomonascus clade (Saccharomycotina, Ascomycota), including four Trichomonascus species and 19 anamorphic species presently classified in Blastobotrys, were tested for their ability to convert the trichothecene T-2 toxin to less-toxic products. These species gave three types of biotransformations: acetylation to 3-acetyl T-2 toxin, glycosylation to T-2 toxin 3-glucoside, and removal of the isovaleryl group to form neosolaniol. Some species gave more than one type of biotransformation. Three Blastobotrys species converted T-2 toxin into T-2 toxin 3-glucoside, a compound that has been identified as a masked mycotoxin in Fusarium-infected grain. This is the first report of a microbial whole-cell method for producing trichothecene glycosides, and the potential large-scale availability of T-2 toxin 3-glucoside will facilitate toxicity testing and development of methods for detection of this compound in agricultural and other products.

However, little is known regarding post-fire seedling performance and its association with environmental variation in former shrub canopy and interspace microsites. We compared post-fire seeding success and various soil properties important for seedling establishment between shrub canopy and interspace microsites in Wyoming big sagebrush (Artemisia tridentata) plant communities in southeast Oregon, U.S.A. We burned 5, 20 20 m sites and established paired canopy and interspace micro-transects seeded with bluebunch wheatgrass (Pseudoroegneria spicata, 193 seeds/m) or crested wheatgrass (Agropyron cristatum, 177 seeds/m). At one year post-fire, seedling density was 69% higher (p = 0.012) for crested wheatgrass (compared to bluebunch wheatgrass) and 75% higher (p = 0.019) for interspace microsites (compared to canopy). However, tiller and leaf area production were over twice as high (p < 0.05) in canopy microsites. Soil color and soil temperature, explained 19-32% of variation in seedling performance metrics. Shrub effects on seeding success are complex and interact with abiotic disturbances, but patterns of increased seedling performance in canopy microsites and their relationships to soil variables may suggest tactics for increasing success of restoration practices.

These high-value chemicals are usually synthesized by chemical methods but biological synthesis adds market value. Ferulic acid, a relatively inexpensive component of agricultural crops, is plentiful in corn hulls, cereal bran, and sugar-beet pulp. Two Enterobacter strains, E. soli, and E. aerogenes, accumulated 550-600 ppm amounts of 4-VG when grown in media containing 1,000 ppm ferulic acid; no accumulations were observed with the other strains. Decreasing the amount of ferulic acid present in the media increased the conversion efficiency. When ferulic acid was supplied in 500, 250, or 125 ppm amounts E. aerogenes converted ~72 % of the ferulic acid present to 4-VG while E. soli converted ~100 % of the ferulic acid to 4-VG when supplied with 250 or 125 ppm amounts of ferulic acid. Also, lowering the pH improved the conversion efficiency. At pH 5.0 E. aerogenes converted ~84 % and E. soli converted ~100 % of 1,000 ppm ferulic acid to 4-VG. Only small, 1-5 ppm, accumulations of vanillin, vanillyl alcohol, and vanillic acid were observed. E. soli has a putative phenolic acid decarboxylase (PAD) that is 168 amino acids long and is similar to PADs in other enterobacteriales; this protein is likely involved in the bioconversion of ferulic acid to 4-VG. E. soli or E. aerogenes might be useful as a means of biotransforming ferulic acid to 4-VG.

Only a few efforts have been made to assess the effect of As-Se mixture in algae or plants in general. Due to the lack of information on this topic, the aim of this study was to examine the As-Se interactive effect in the alga species Desmodesmus quadricauda. The initial density of algal cells was 1.9 x 10 super(4), cultures were permanently illuminated (70 mu Em super(-2) s super(-1)) and As and Se adverse effect was expressed as EC (effective concentration) value. For all experiments three EC (EC sub(10), EC sub(20), EC sub(50)) values for both metalloids were used: for As 26.20, 29.05, 35.38 mg L super(-1) and for Se 1.93, 3.65, 12.24 mg L super(-1), respectively. During this study algal biomass growth, lipid peroxidation and protein-bound thiol content parameters were used to assess the As-Se interactions. The reciprocal effect of the elements on their uptake by the alga was also determined. The As-treated algae supplemented with Se exhibited impaired growth indicating a synergistic interaction between the two elements. In samples treated with As-Se mixture, the total algal As content showed marked increase depending on the Se concentration in the mixture. Se uptake was also positively affected by rising As concentrations in the mixture. Consequently, the As-Se-treated algae experienced greater damage to membranes, evidenced by marked elevation of the TBARS (thiobarbituric acid reactive substances) content. The TBARS content increased to a maximum level by 29.05 mg L super(-1) of As and 3.65 mg L super(-1) of Se, which was around 70 percent higher than that of the control. The thiol content was very close to that of the control treatment over the entire concentration range and for all As and Se combinations tested. Possible explanation for the synergism observed in D. quadricauda, is that the elevated uptake of As and Se upon their interaction and impaired antioxidant system, has added to the toxicity of the elements.

Life cycle assessments (LCA) for bioenergy crops have been conducted using models in which SOC information is usually from the top 30 to 40 cm. Information on the effects of crop management practices on SOC has been limited so LCA models have largely not included any management practice effects. In the first 9 years of a long-term C sequestration study in eastern Nebraska, USA, switchgrass and maize with best management practices had average annual increases in SOC per hectare that exceed 2 Mg Cyear super(-1) (7.3 Mg CO sub(2)year super(-1)) for the 0 to 150 soil depth. For both switchgrass and maize, over 50 % of the increase in SOC was below the 30 cm depth. SOC sequestration by switchgrass was twofold to fourfold greater than that used in models to date which also assumed no SOC sequestration by maize. The results indicate that N fertilizer rates and harvest management regimes can affect the magnitude of SOC sequestration. The use of uniform soil C effects for bioenergy crops from sampling depths of 30 to 40 cm across agro-ecoregions for large scale LCA is questionable.

In sorghum and other C4 grasses, the brown midrib mutants have been shown to reduce lignin content and alter its composition. Bmr12 encodes the sorghum caffeic O-methyltransferase, which catalyzes the penultimate step in monolignol biosynthesis. From an EMS-mutagenized TILLING population, four bmr12 mutants were isolated. DNA sequencing identified the four missense mutations in the Bmr12 coding region, which changed evolutionarily conserved amino acids Ala71Val, Pro150Leu, Gly225Asp, and Gly325Ser. The previously characterized bmr12 mutants all contain premature stop codons. These newly identified mutants, along with the previously characterized bmr12-ref, represent the first allelic series of bmr12 mutants available in the same genetic background. The impacts of these newly identified mutations on protein accumulation, enzyme activity, Klason lignin content, lignin subunit composition, and saccharification yield were determined. Gly225Asp mutant greatly reduced protein accumulation, and Pro150Leu and Gly325Ser greatly impaired enzyme activity compared to wild type (WT). All four mutants significantly reduced Klason lignin content and altered lignin composition resulting in a significantly reduced S/G ratio relative to WT, but the overall impact of these mutations was less severe than bmr12-ref. Except for Gly325Ser, which is a hypomorphic mutant, all mutants increased the saccharification yield relative to WT. These mutants represent new tools to decrease lignin content and S/G ratio, possibly leading toward the ability to tailor lignin content and composition in the bioenergy grass sorghum.

We sought to empirically test the long-held belief that Tamarix actively displaces native species through elevating soil salinity via salt exudation. We measured chemical and physical attributes of soils (e.g., salinity, major cations and anions, texture), litter cover and depth, and stand structure along chronosequences dominated by Tamarix and those dominated by native riparian species (Populus or Salix) along the upper and lower Colorado River in Colorado and Arizona/California, USA. We tested four hypotheses: (1) the rate of salt accumulation in soils is faster in Tamarix-dominated stands than stands dominated by native species, (2) the concentration of salts in the soil is higher in mature stands dominated by Tamarix compared to native stands, (3) soil salinity is a function of Tamarix abundance, and (4) available nutrients are more concentrated in native-dominated stands compared to Tamarix-dominated stands. We found that salt concentration increases at a faster rate in Tamarix-dominated stands along the relatively free-flowing upper Colorado but not along the heavily-regulated lower Colorado. Concentrations of ions that are known to be preferentially exuded by Tamarix (e.g., B, Na, and Cl) were higher in Tamarix stands than in native stands. Soil salt concentrations in older Tamarix stands along the upper Colorado were sufficiently high to inhibit germination, establishment, or growth of some native species. On the lower Colorado, salinity was very high in all stands and is likely due to factors associated with floodplain development and the hydrologic effects of river regulation, such as reduced overbank flooding, evaporation of shallow ground water, higher salt concentrations in surface and ground water due to agricultural practices, and higher salt concentrations in fine-textured sediments derived from naturally saline parent material.

Genetic diversity among 151 isolates, taken from a disease resistance breeding trial, was assessed using seven random amplified polymorphic DNA (RAPD) primers and sequence analyses of portions of the internal transcriber spacer (ITS) region and Alt a1 gene. A. solani isolates were grouped into 19 RAPD profiles to examine the distribution patterns of genetically distinct isolates within and between years. Seven RAPD profiles were found spanning both years with profiles 6 and 13 being the most prevalent. Five unique profiles were found only in 2008 and seven were found only in 2009. No variation was observed among isolates of A. solani based on ITS and Alt a1 sequence analyses, but a distinction between A. solani and A. dauci, a close relative outgroup was identified. Pathogenicity was also assessed using a tissue culture plantlet assay on four isolates and two reference cultures. Differences in virulence were observed among the isolates examined.

Spatially-intensive fire and forest histories provide valuable information about how fire and vegetation may vary and interact on heterogeneous landscapes. I constructed 800-year fire and tree recruitment chronologies for two eastern Great Basin fire-sheds using fire-scar and tree establishment evidence from 48 gridded plots (500m spacing) and from fire-scarred trees between plots. Fire-sheds are located in the Snake Range of eastern Nevada (BMC) and Wah Wah Range of western Utah (LAW) and span a range in elevation and vegetation zones typical for the region. Estimates of point mean fire interval varied more than 10-fold at both BMC (7.8-125.6years) and LAW (13.3-138.4years). At BMC, a distinct within-fire-shed contrast in fire frequency was difficult to explain without invoking the possibility of spatially-variable human-caused ignitions. A majority of fires were small (=100ha) accounted for 78% (BMC) to 89% (LAW) of cumulative area burned. Tree recruitment for mid-elevation, mixed-conifer stands was somewhat episodic and asynchronous among plots. Recruitment pulses were synchronous with multi-decade fire quiescent periods, and often followed large fires. I concluded that fire frequency was under strong topographic control and that fire severity was mixed and variable through time and space resulting in a dynamic mosaic of variable-aged, fire-initiated vegetation intermixed with long-lived, fire-resilient trees and open shrub-steppe communities (BMC). A major change in fire regime and forest composition began in the 1800s cusing shifts in composition and structure at the stand scale and homogenization at the landscape scale. I recommend that management strategies prioritize the use of fire and surrogate treatments on mid-elevation forests that have deviated most from historic conditions and on associated shrub-steppe communities where conifer encroachment has occurred. Planned disturbances should be of mixed severity and sized to recreate vegetative mosaics at historic spatial scales.

The mortality models presented here are developed from long-term permanent plots in provinces from throughout the geographic range of ponderosa pine in the United States extending from the Black Hills of South Dakota to the Pacific Coast. The study had two objectives: estimation of the probability of a tree survival for the next 5years and the probability of a tree surviving longer than a given time period (survival trend) for a given set of covariates. The probability of a tree surviving for the next 5years was estimated using a logistic model regressed on 18 covariates measured 5years before the last measurement period with 15 smoothing variables (S1-S15) for spatial effects of latitude and longitude surface. The fitted model showed that the probability of survival increased with increasing diameter at breast height (DBH), DBH periodic annual increment (PAIDBH) and increasing plot basal area/number of trees per hectare (PBAH/TPH), and decreased with increasing average of the 5 tallest trees in the plot (AVGHT5) when other selected covariates were included in the model. The probability of a tree surviving longer than a given time period was estimated by fitting the Cox Proportional Hazard model to the last observed survival period regressed on 13 covariates measured at the first measurement period. This probability also increased with increasing DBH and PAIDBH, and decreased with increasing AVGHT5. The Akaike's Information Criterion (AIC) and graphs of partial residuals were used in the selection of covariates included in the models.

To succeed, we suggest use of formal decision science procedures and tools in the context of structured decision making (SDM). SDM entails four stages: problem structuring (framing the problem and defining objectives and evaluation criteria), problem analysis (defining alternatives, evaluating likely consequences, identifying key uncertainties, and analyzing tradeoffs), decision point (identifying the preferred alternative), and implementation and monitoring the preferred alternative with adaptive management feedbacks. We list a wide array of models, techniques, and tools available for each stage, and provide three case studies of their selected use in National Forest land management and project plans. Successful use of SDM involves participation by decision-makers, analysts, scientists, and stakeholders. We suggest specific areas for training and instituting SDM to foster transparency, rigor, clarity, and inclusiveness in formal decision processes regarding management of national forests.

In this study six organisms isolated from commercial spoiled cucumber pickles were evaluated for their possible role in primary and secondary cucumber fermentations. The ability of the yeasts Issatchenkia occidentalis and Pichia manshurica to utilize lactic and acetic acids during aerobic metabolism was confirmed and associated with increases in brine pH and the chemical reduction of the fermentation matrix. Lactobacillus buchneri and Pediococcus ethanolidurans were able to produce lactic acid from sugars, but only L. buchneri produced acetic acid at the expense of lactic acid under both aerobic and anaerobic conditions regardless of the initial acidic pH of 3.2 in the medium. The formation of secondary products was associated with the metabolism of Clostridium bifermentans and Enterobacter cloacae, which metabolic activity was observed at medium pH above 4.5. Individually, the selected spoilage microorganisms were found to be able to produce changes associated with secondary cucumber fermentations. The fact that oxidative yeasts and L. buchneri were able to produce chemical changes associated with the initiation of the spoilage process indicates that prevention of the secondary fermentation could be achieved by inhibiting these organisms.

The issue has become more prevalent as human residences move into areas once occupied only by agriculture. Odors near AFOs are generally caused by odorous VOCs emitted from manure, the mixture of feces and urine. Wet distillers grains with solubles (WDGS) are a by-product of the ethanol industry, and WDGS have become a staple in many beef cattle finishing diets. The objective of this research was to determine specific VOC emissions from frozen feces and urine of cattle fed steam-flaked corn (SFC)-based diets containing 0, 15, 30, or 45% WDGS. No differences in flux were detected across dietary treatments for phenol, indole, skatole, or 4-methylphenol (P > 0.23). Dimethyl disulfide and dimethyl trisulfide flux in feces were not different across treatments (P > 0.35) and the flux of volatile fatty acids (VFA) such as acetic, propionic, isobutyric, butyric, isovaleric, and valeric were not different across treatments (P > 0.25). There was a tendency for dimethyl disulfide flux from urine to be greater for cattle consuming an SFC-based diet with 15% WDGS than the other diets (P = 0.10). Furthermore, flux of acetic, propionic, isobutyric, butyric, and isovaleric acid from the urine were not different (P > 0.61) across dietary treatment. There were no significant differences in odor activity value (OAV) across treatments for feces, and only a tendency for dimethyl disulfide in the feces (P = 0.09). Thus, there was no obvious indication that feeding WDGS in conjunction with SFC affects flux of odor or odorous VOC from beef manure. The summed OAV was three times higher in the urine than feces, and a single odorous compound (4-methylphenol) accounted for 97.6%and 67.3% of the OAV in urine and feces, respectively. Therefore, engineering or dietary strategies to reduce odor from beef cattle manure should focus on controlling or reducing 4-methylphenol concentrations in the urine and feces.

The objectives of this study were to determine effects of crop rotation on corn yield, water use, and nitrogen (N) use. No-tillage (NT) crop rotations were started in 1997 on a Barnes clay loam (fine-loamy, mixed, superactive, frigid Calcic Hapludoll) near Brookings, S.D. Rotations were continuous corn (CC), corn-soybean [Glycine max (L.) Merr.] (CS), a 3-year rotation of corn-soybean-oat/pea (Avena sativa L. and Pisum sativum L.) hay (CSH), a 3-year rotation of corn-soybean-spring wheat (Triticum aestivum L.) (CSW), and a 5-year rotation of corn-soybean-oat/pea hay companion seeded with alfalfa (Medicago sativa L.)-alfalfa-alfalfa (CSHAA). Fertilizer N was applied to corn on all rotations at planting (16 kg N ha super(-1)) and side-dressed (64 kg N ha super(-1)). Average corn grain yields (1998-2007) were greatest under CSW (7.38 Mg ha super(-1)) and least under CC (4.66 Mg ha super(-1)). Yields were not different among CSH, CSW, and CSHAA rotations. Water-use efficiency of rotation was ordered as CSW > 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.

It is therefore beneficial to develop simple analytical tools to assist belowground carbon estimation where financial and technical limitations are common. Here we use published and original data to describe soil carbon density (kgC m super(-3); C sub(d)) as a function of bulk density (gC cm super(-3); B sub(d)), which can be used to rapidly estimate belowground carbon storage using B sub(d) measurements only. Predicted carbon densities and stocks are compared with those obtained from direct carbon analysis for ten peat swamp forest stands in three national parks of Indonesia. Analysis of soil carbon density and bulk density from the literature indicated a strong linear relationship (C sub(d) = B sub(d) 495.14 + 5.41, R super(2) = 0.93, n = 151) for soils with organic C content > 40%. As organic C content decreases, the relationship between C sub(d) and B sub(d) becomes less predictable as soil texture becomes an important determinant of C sub(d). The equation predicted belowground C stocks to within 0.92% to 9.57% of observed values. Average bulk density of collected peat samples was 0.127 g cm super(-3), which is in the upper range of previous reports for Southeast Asian peatlands. When original data were included, the revised equation C sub(d) = B sub(d) 468.76 + 5.82, with R super(2) = 0.95 and n = 712, was slightly below the lower 95% confidence interval of the original equation, and tended to decrease C sub(d) estimates. We recommend this last equation for a rapid estimation of soil C stocks for well-developed peat soils where C content > 40%.

17319020 AB - Managers of the nearly 0.5 million ha of public lands in North and South Dakota, USA rely heavily on manual measurements of canopy height in autumn to ensure conservation of grassland structure for wildlife and forage for livestock. However, more comprehensive assessment of vegetation structure could be achieved for mixed-grass prairie by integrating field survey, topographic position (summit, mid and toeslope) and spectral reflectance data. Thus, we examined the variation of mixed-grass prairie structural attributes (canopy leaf area, standing crop mass, canopy height, nitrogen, and water content) and spectral vegetation indices (VIs) with variation in topographic position at the Grand River National Grassland (GRNG), South Dakota. We conducted the study on a 36,000-ha herbaceous area within the GRNG, where randomly selected plots (1 km super(2) in size) were geolocated and included summit, mid and toeslope positions. We tested for effects of topographic position on measured vegetation attributes and VIs calculated from Landsat TM and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data collected in July 2010. Leaf area, standing crop mass, canopy height, nitrogen, and water content were lower at summits than at toeslopes. The simple ratio of Landsat Band 7/Band 1 (SR71) was the VI most highly correlated with canopy standing crop and height at plot and landscape scales. Results suggest field and remote sensing-based grassland assessment techniques could more comprehensively target low structure areas at minimal expense by layering modeled imagery over a landscape stratified into topographic position groups.

Eighty-four, 6-week-old, cross-bred pigs were randomly allocated into 3 groups of 28 pigs to represent vaccinated/challenged (V/C), non-vaccinated/challenged (NV/C), and non-vaccinated/non-challenged (NV/NC) control groups. Pigs were intratracheally inoculated with pH1N1and euthanized at 1, 2, 5, and 21 days post inoculation (dpi). Macroscopically, V/C pigs demonstrated greater percentages of pneumonia compared to NV/C pigs. Histologically, V/C pigs demonstrated severe bronchointerstitial pneumonia with necrotizing bronchiolitis accompanied by interlobular and alveolar edema and hemorrhage at 1 and 2 dpi. The magnitude of peribronchiolar lymphocytic cuffing was greater in V/C pigs by 5 dpi. Microscopic lung lesion scores were significantly higher in the V/C pigs at 2 and 5 dpi compared to NV/C and NV/NC pigs. Elevated TNF- alpha , IL-1 beta , IL-6, and IL-8 were detected in bronchoalveolar lavage fluid at all time points in V/C pigs compared to NV/C pigs. These data suggest H1 inactivated vaccines followed by heterologous challenge resulted in potentiated clinical signs and enhanced pulmonary lesions and correlated with an elevated proinflammatory cytokine response in the lung. The lung alterations and host immune response are consistent with the vaccine-associated enhanced respiratory disease (VAERD) clinical outcome observed reproducibly in this swine model.

At the same time, spring juvenile to adult female ratios of Rocky Mountain elk (Cervus elaphus) have been declining. This has raised concern that archery seasons may be disrupting elk breeding and contributing to the decline in recruitment. Two mechanisms could contribute to reduced juvenile:female ratios: 1) reduced pregnancy rates, and 2) delayed conception dates because of human disturbance during the rut. We varied the number of archery hunters at the Starkey Experimental Forest and Range over 13 years to evaluate effects of archer density on reproduction of elk. Archer densities were maintained at high densities during 4 years x = 1.09 tags sold/km super(2)), low densities during 3 years x = 0.53tags sold; /km super(2)), and no archers during 6 years. We determined pregnancy status, age, kidney fat index (KFI), lactation status, and fetus conception dates for 622 female elk harvested in December. We found pregnancy rate differences of 0.105, 0.080, and 0.021 between high and no archer density years (P=0.004), high and low archer density years (P=0.054), and low and no archer density years (P=0.616), respectively. Conception dates were 4 days later for high archer density compared to low archer density (P=0.006), but did not differ between high and no archer years (2 days; P=0.136) or between low and no archer years (2 days; P=0.108). We compared generalized linear model estimates of pregnancy rates and determined pregnancy rates for 28% of the lactating female elk to be affected by high archer density, whereas archer densities had no significant affect on pregnancy rate estimates for non-lactating females. We found no difference in conception dates among archer densities when comparing model estimates. Our results suggest that archer density and its interaction with nutritional condition of elk influence pregnancy rates of lactating females with low KFI levels; however, the effect of archer density alone does not explain the magnitude of decline in juvenile to female ratios observed in Oregon.

They are attracted to fermented sweet materials, such as decomposing fruits but also wines and vinegars, and to ubiquitous fermentation volatiles, such as acetic acid and ethanol. Gas chromatography coupled with electroantennographic detection (GC-EAD), gas chromatography-mass spectrometry (GC-MS), two-choice laboratory bioassays, and field trapping experiments were used to identify volatile compounds from wine and vinegar that are involved in SWD attraction. In addition to acetic acid and ethanol, consistent EAD responses were obtained for 13 volatile wine compounds and seven volatile vinegar compounds, with all of the vinegar EAD-active compounds also present in wine. In a field trapping experiment, the 9-component vinegar blend and 15-component wine blend were similarly attractive when compared to an acetic acid plus ethanol mixture, but were not as attractive as the wine plus vinegar mixture. In two-choice laboratory bioassays, 7 EAD-active compounds (ethyl acetate, ethyl butyrate, ethyl lactate, 1-hexanol, isoamyl acetate, 2-methylbutyl acetate, and ethyl sorbate), when added singly to the mixture at the same concentrations tested in the field, decreased the attraction of SWD to the mixture of acetic acid and ethanol. The blends composed of the remaining EAD-active chemicals, an 8-component wine blend [acetic acid + ethanol + acetoin + grape butyrate + methionol + isoamyl lactate + 2-phenylethanol + diethyl succinate] and a 5-component vinegar blend [acetic acid + ethanol + acetoin + grape butyrate + 2-phenylethanol] were more attractive than the acetic acid plus ethanol mixture, and as attractive as the wine plus vinegar mixture in both laboratory assays and the field trapping experiment. These results indicate that these volatiles in wine and vinegar are crucial for SWD attraction to fermented materials on which they feed as adults.

II): Rationale, Design, and Methods AN - 1347818692; 201307702 AB - Background: Youths eat fewer fruits and vegetables than recommended. Effective methods are needed to increase and maintain their fruit and vegetable consumption. Goal setting has been an effective behavior change procedure among adults, but has had limited effectiveness among youths. Implementation intentions are specific plans to facilitate goal attainment. Redefining goal setting to include implementation intentions may be an effective way to increase effectiveness. Video games offer a controlled venue for conducting behavioral research and testing hypotheses to identify mechanisms of effect. Objective: This report describes the protocol that guided the design and evaluation of Squire's Quest! II, a video game aimed to increase child fruit and vegetable consumption. Methods: Squire's Quest! II is a 10-episode videogame promoting fruit and vegetable consumption to 4th and 5th grade children (approximately 9-11 year old youths). A four group randomized design (n=400 parent/child dyads) was used to systematically test the effect of two types of implementation intentions (action, coping) on fruit and vegetable goal attainment and consumption of 4th and 5th graders. Data collection occurred at baseline, immediately post game-play, and 3 months later. Child was the unit of assignment. Three dietary recalls were collected at each data collection period by trained interviewers using the Nutrient Data System for Research (NDSR 2009). Psychosocial and process data were also collected. Results: To our knowledge, this is the first research to explore the effect of implementation intentions on child fruit and vegetable goal attainment and consumption. Conclusions: This intervention will contribute valuable information regarding whether implementation intentions are effective with elementary age children.

We argue that progression from steady-state management to ecosystem management has served the rangeland profession well, but that further development toward resilience-based management is required to ensure that ecosystem services are sustained in an era of rapid change. Resilience-based management embraces the inevitability of change and emphasizes that management should seek to guide change to benefit society. The objectives of this forum are to: 1) justify the need for adopting resilience-based management, 2) identify the challenges that will be encountered in its development and implementation, and 3) highlight approaches to overcoming these challenges. Five grand challenges confronting the adoption of resilience-based management, based upon the insights of 56 rangeland researchers who have contributed to this special issue, were identified as: 1) development of knowledge systems to support resilience-based management, 2) improvement of ecological models supporting science and management, 3) protocols to assess and manage tradeoffs among ecosystem services, 4) use of social-ecological system models to integrate diverse knowledge sources, and 5) reorganization of institutions to support resilience-based management. Resolving the challenges presented here will require the creation of stronger partnerships between ecosystem managers, science organizations, management agencies, and policymakers at local, regional, and national scales. A realistic near-term goal for achieving such partnerships is to initiate and support collaborative landscape projects. The creation of multiscaled social learning institutions linked to evolving knowledge systems may be the best approach to guide adaptation and transformation in rangelands in the coming century. Los contextos ecologicos y sociales para el manejo de pastizales estan cambiando rapidamente, provocando una reevaluacion de la ciencia, y los vinculos entre ellos. Aqui proponemos que el reciente cambio de enfoque de un estado constante a un modelo de manejo de ecosistema ha servido bien a la profesion de manejo de pastizales, pero es necesario un cambio adicional al manejo basado en resiliencia que garantice que los servicios de los pastizales continuaran beneficiando a la sociedad en una era de cambios rapidos. El manejo basado en la resiliencia enfatiza el manejo colaborativo y el aprendizaje social para guiar la adopcion y transformacion en sistemas ecologico-sociales. Los objetivos de este foro son 1) justificar le necesidad para adoptar manejo basado en la resiliencia, 2) identificar los desafios que se interpondran en el camino para su desarrollo e implementacion y 3) destacar los enfoques para superar estos desafios. Se identificaron cinco categorias de desafios de un manejo basado en resiliencia, usando las ideas de 55 cientificos especializados en el manejo de pastizales que han contribuido especialmente a este tema: a) desarrollo de sistemas de conocimiento para soportar los sistemas de manejo basado en resiliencia, b) mejoramiento de modelos ecologicos apoyados por la ciencia y manejo, c) protocolos para evaluar y manejar el intercambio entre los servicios del ecosistema, d) uso de sistemas de perspectivas socio ecologicas para lograr una mayor participacion de los interesados, y e) reorganizacion de las instituciones para apoyar el manejo basado en resiliencia. Se ha hecho evidente que un mayor conocimiento cientifico por si mismo es insuficiente para promover los modelos de manejo basado en resiliencia en los pastizales. Las soluciones de los retos que se presentan aqui requeriran de la creacion de asociaciones mas fuertes entre manejadores de ecosistemas, organizaciones cientificas, agencias de manejo y los creadores de politicas a nivel local, regional y nacional. La creacion de instituciones sociales de aprendizaje vinculadas a la evolucion de los sistemas de conocimiento es nuestra esperanza para guiar la adaptacion y transformacion en pastizales en el presente siglo.

Current tools for knowledge discovery and application are limited because they cannot adequately judge ecological relevance of knowledge to specific situations. We propose development of integrated knowledge systems (KSs)-collections of resources (e.g., data, analytical tools, literature) drawn from disparate domains and organized around topics by process-based conceptual models. An integrated KS would define relevance by ecological attributes (e.g., soils, climate, vegetation) and location as a flexible mechanism for organizing, finding, and applying knowledge to rangeland management. A KS provides knowledge sources within a decision-making framework that defines what knowledge is needed and how it will be used to make decisions. Knowledge from a KS can identify appropriate spatial and temporal scales to address specific resource questions or objectives. Several factors currently limit KS development and implementation. These include limited interoperability of disparate information and knowledge systems; lack of consistent geographic referencing of knowledge; incomplete and inconsistent documentation of the origin, history and meaning of data and information; underexploited application of remote sensing products; limited ability to extrapolate and share local knowledge and unstructured information; and lack of training and education of professionals that can link ecological and technical fields of study. The proposed KS concept and recommendations present an opportunity to take advantage of emerging technologies and the collective knowledge of rangeland professionals to address changing ecosystems and evolving threats. If we keep on with a "business as usual" approach to finding and using information, we will struggle to meet our responsibilities as rangeland professionals. Adaptar lo que actualmente sabemos acerca de los ecosistemas a un futuro donde los pastizales han cambiando es una nueva frontera en el manejo de pastizales. Las herramientas que existen en la actualidad para el descubrimiento del conocimiento y su aplicacion son limitadas porque no pueden juzgar adecuadamente la relevancia ecologica del conocimiento para situaciones especificas. Propusimos el desarrollo de sistemas de conocimiento integrales (KSs)-colecciones de recursos (ej., datos, herramientas analiticas, literatura) elaborado a partir de areas diferentes y organizados en torno a temas por procesos basado en modelos conceptuales. Un KS integrado podria definir la relevancia por atributos ecologicos (ej., suelos, climas, vegetacion) y la locacion como un mecanismo flexible para organizar, encontrar, la aplicacion de conocimiento al manejo de pastizales. Un KS provee fuentes de conocimiento dentro de un marco de toma de decisiones que define que conocimiento es necesitado y como va a usarse para tomar decisiones. El conocimiento de un KS puede identificar escalas espaciales apropiadas y temporales para responder preguntas de recursos especificas u objetivos. Varios factores en la actualidad limitan el desarrollo y la implementacion de KS. Entre ellos encontramos: interoperabilidad limitada de informacion dispar y los sistemas de conocimiento. Falta de referencias geograficas consistentes del conocimiento; documentacion incompleta e inconsistente de documentacion de origen, historia y significado de datos e informacion; aplicacion sin explorar de los productos de teleobservacion; habilidad limitada para extrapolar y compartir conocimiento local e informacion no estructurada; y entrenamiento y educacion de profesionales que pueden unir los campos de estudios ecologicos y tecnicos. El concepto KS propuesto y las recomendaciones son una oportunidad para aprovechar las tecnologias emergentes y el conocimiento colectivo de los pastizales para hacer frente al cambio de los ecosistemas y los riegos cambiantes. Si seguimos con un enfoque tradicional para encontrar y usar informacion, vamos a enfrentar serias dificultades para cumplir con nuestras responsabilidades como profesionales de los pastizales.

Identifying a restoration target entails defining an ecosystem state and its desired functioning that can be attained through managerial interventions. First, we discuss how restoration targets must integrate economic, social, and ecological considerations in order to be feasible. Primary challenges to identifying realistic restoration targets include long-term managerial and fiscal commitments as well as the accommodation of inherent rangeland complexities stemming from social and ecological factors. Second, we illustrate how the existing tools of ecological site description, rangeland health assessment, and state-and-transition modeling present opportunities to identify flexible restoration targets. Last, we describe how to refine these targets using adaptive management in order to cope with constraints and to reduce the uncertainty of ecosystem dynamics typical of complex systems. Restoration should be viewed as both a rangeland management activity and a means to inform and guide interventions within a specific site. Las actividades de rehabilitacion estan dirigidas hacia un amplio espectro de objetivos. La identificacion de un objetivo de rehabilitacion implica la definicion del estado del ecosistema y el funcionamiento deseado que puede alcanzarse a traves de intervenciones de manejo. Primero, discutimos como los objetivos de rehabilitacion deben integrar factores economicos, sociales y ecologicos, con el fin de ser factibles. Los principales desafios para la identificacion de objetivos realistas de rehabilitacion incluyen compromisos de manejo y economicos a largo plazo. Asi tambien deben incluirse otros elementos innatos de los pastizales derivados de los factores sociales y ecologicos. Segundo, ilustramos como la existencia de herramientas para descripcion ecologica de los sitios, evaluacion del bienestar del pastizal, y el modelado del estado y transicion representan oportunidades para identificar objetivos de rehabilitacion. Finalmente, describimos como redefinir estos objetivos usando manejo adaptativo con el fin de hacer frente a limitaciones y reducir la incertidumbre de la dinamica de los ecosistemas tipicamente de los sistemas complejos. La rehabilitacion debe ser vista tanto como una actividad del manejo de pastizales como de un medio para informar y guiar las mediaciones en un sitio especifico.

AN - 1328514955; 17401271 AB - Rapidly increasing demand for food, fiber, and fuel together with new technologies and the mobility of global capital are driving revolutionary changes in land use throughout the world. Efforts to increase land productivity include conversion of millions of hectares of rangelands to crop production, including many marginal lands with low resistance and resilience to degradation. Sustaining the productivity of these lands requires careful land use planning and innovative management systems. Historically, this responsibility has been left to agronomists and others with expertise in crop production. In this article, we argue that the revolutionary land use changes necessary to support national and global food security potentially make rangeland science more relevant now than ever. Maintaining and increasing relevance will require a revolutionary change in range science from a discipline that focuses on a particular land use or land cover to one that addresses the challenge of managing all lands that, at one time, were considered to be marginal for crop production. We propose four strategies to increase the relevance of rangeland science to global land management: 1) expand our awareness and understanding of local to global economic, social, and technological trends in order to anticipate and identify drivers and patterns of conversion; 2) emphasize empirical studies and modeling that anticipate the biophysical (ecosystem services) and societal consequences of large-scale changes in land cover and use; 3) significantly increase communication and collaboration with the disciplines and sectors of society currently responsible for managing the new land uses; and 4) develop and adopt a dynamic and flexible resilience-based land classification system and data-supported conceptual models (e.g., state-and-transition models) that represent all lands, regardless of use and the consequences of land conversion to various uses instead of changes in state or condition that are focused on a single land use. La creciente demanda de alimentos, fibras y combustibles de manera simultanea con las nuevas tecnologias y la movilidad global del capital estan ocasionando cambios revolucionados en el uso de la tierra en todo el mundo. Los esfuerzos para incrementar la productividad de la tierra incluyen la conversion de millones de hectareas de pastizales a la produccion de granos, incluyendo tierras marginales con bajo resistencia y resilencia a la degradacion. Sostener la productividad de estas tierras requiere planeacion cuidadosa del uso de la tierra y sistemas de manejo innovadores. Historicamente, esta responsabilidad se ha dejado a agronomos y otros expertos en produccion de granos. En este articulo, discutimos que los revolucionados cambios en uso de la tierra necesarios para sostener la seguridad alimentaria nacional y mundial potencialmente hacen a la ciencia del pastizal mas relevante ahora que nunca. Mantener e incrementar esa relevancia requerira de cambios revolucionarios en la ciencia del pastizal de una disciplina que se enfoca en un uso particular de la tierra o cubierta vegetal a una que considere el reto de manejar todas las tierras que en algun tiempo fueron consideradas marginales para la produccion de granos. Proponemos cuatro estrategias para aumentar la relevancia de la ciencia del pastizal a un manejo global de la tierra: 1) extender nuestra conocimiento y concientizacion del ambito local a tendencias globales economicas, sociales y tecnologicas con el fin de anticipar e identificar conductores y patrones de conversion, 2) enfatizar en estudios empiricos y modelaje que anticipe las consecuencias biofisicas (servicios de los ecosistemas) y sociales de cambios en la cobertura y uso de la tierra en gran escala, 3) aumentar significativamente la comunicacion y colaboracion con las disciplinas y sectores de la sociedad actualmente responsables en el manejo del nuevo uso de la tierra, y 4) desarrollar y adoptar un sistema de clasificacion dinamica y flexible basado en la resilencia de la tierra y modelos conceptuales apoyados en datos (ejm. Modelos de Estado y Transicion) que representan todas las tierras, independientemente del uso y las consecuencias en la conversion de tierras para varios usos el lugar de cambios en el estado y condicion que se enfocan en un solo uso de la tierra.

Competing land uses and continued encroachment of woody species into non-woody-dominated rangelands have reduced grasslands in many parts of the world. Land use conversions to fuel and feed global populations, especially the increasing number of middle class people seeking broader, meat-based diets, will certainly continue. Halting and/or reversing further encroachment of woody species into grasslands is slow, expensive, and in some cases not possible. Yet, global livestock numbers continue to increase to meet the growing demand for red meat and other livestock products. How do we reconcile a world with less grass and the concurrent increased demand for forages to feed livestock? Strategies and mechanisms are needed to safely enhance shrub use by ruminants in order to capitalize on a presently underutilized forage resource. A number of approaches are presently available (e.g., choosing appropriate species and breeds, providing dietary supplements and additives, behavior modification, genetic selection) to increase shrub consumption, and new technologies such as biochemical markers of shrub intake need to continue to be identified and developed. Such strategies could provide important means for rural communities to adapt to changing land cover and climate. La mayor parte de los pastizales del mundo estan dominados por especies lenosas. El cambio de uso de suelo y la continua expansion de especies lenosas dentro de pastizales dominados por no-lenosas ha reducido los pastizales en muchas partes del mundo. La conversion de tierras para abastecer y alimentar la poblacion global, especialmente con el aumento en el numero de personas de clase media que buscan dietas basadas en carne ciertamente continuara. El vacilante y/o posible re vertimiento de la invasion de especies lenosas en los pastizales es lento, caro y en algunos casos imposible. De hecho, el numero global de ganado continuara creciendo para cubrir la demanda de carne roja y otros productos derivados del ganado. [iquest]Como podemos conciliar a un mundo con menos pasto y la creciente demanda de forrajes para alimentar el ganado? Se necesitan estrategias y mecanismos que de manera segura promuevan el uso de arbustos por los rumiantes con el fin de capitalizar los recursos forrajeros subutilizados actualmente. Hay disponibilidad de puntos de vista (ejm. Seleccionar razas y especies apropiadas, proveer suplementos dieteticos y aditivos, modificar el comportamiento, seleccion genetica) para aumentar el consumo de arbustos y nuevas tecnologicas tales como los marcadores bioquimicos en consumo de arbustos que se necesita continuar en la identificacion y desarrollo de estos. Estas estrategicas pueden ofrecer importantes medios en las comunidades rurales para adaptar en la cambiante cobertura del suelo y el clima.

The Conundrum of Rangeland Science in the 21st Century AN - 1328514663; 17401270 AB - A critical challenge for range scientists is to provide input to management decisions for land units where little or no data exist. The disciplines of range science, basic ecology, and global ecology use different perspectives and approaches with different levels of detail to extrapolate information and understanding from well-studied locations to other land units. However, these traditional approaches are expected to be insufficient in the future as both human and climatic drivers change in magnitude and direction, spatial heterogeneity in land cover and its use increases, and rangelands become increasingly connected at local to global scales by flows of materials, people, and information. Here we argue that to overcome limitations of each individual discipline, and to address future rangeland problems effectively, scientists will need to integrate these disciplines successfully and in novel ways. The objectives of this article are 1) to describe the background, historical development, and limitations of current approaches employed by these disciplines; 2) to describe an integrated approach that takes advantage of the strengths and minimizes the weaknesses of these individual approaches; and 3) to discuss the challenges and implications of this integrated approach to the future of range science when climate and human drivers are nonstationary. This integration will be critical for applying range science to the management of specific land units; will contribute to and benefit from the development of general ecological principles; and will assist in addressing problems facing society at regional, continental, and global scales. Un reto muy critico para los cientificos en pastizales es proveer de informacion para toma decisiones de manejo de unidades de tierra donde hay pocos o nulos datos. Las disciplinas de ciencia del pastizal, ecologia basica y ecologia global usan diferentes perspectivas y enfoques con diferentes niveles de detalle para extrapolar la informacion y el conocimiento de lugares bien estudiados a otras unidades de tierra. Sin embargo, estos enfoques tradicionales se espera que sean insuficientes en el futuro porque los humanos y el clima generan cambios en magnitud y direccion, especial heterogeneidad en cubierta del suelo y sus usos se incrementa y los pastizales llegan a estar con en escala local y global por el flujo de materiales, personas e informacion. Aqui discutimos que para sortear las limitaciones de cada disciplina de manera efectiva y atender los problemas de los pastizales, en el futuro los cientificos necesitaran integrar de manera novedosa y exitosa estas disciplinas. Los objetivos de este articulo son 1) describir los antecedentes, desarrollo historico y limitaciones de los enfoques actuales empleados por estas disciplinas, 2) describir un enfoque integrado que resalte las fortalezas y minimice las debilidades de cada enfoque en lo particular y 3) discutir los retos e implicaciones de este enfoque integrado en el futuro de la ciencia del pastizal cuando el clima y los humanos son conductores no pasivos. Esta integracion sera critica para aplicar la ciencia del pastizal para el manejo especifico de unidades de tierra y contribuira para el beneficio en el desarrollo de principios ecologicos y tambien direccionar los problemas que enfrenta la sociedad a escalas regional, continental y global.

Collectively, these models have considerably increased our fundamental knowledge and understanding of the dynamics of ecosystem functions, processes, and structure. We explore three areas where models for rangeland management are often challenging for land managers and enterprise-level decision making: 1) coping with spatiotemporal and climatic variability in implementing scenario forecasting, risk assessments, and adaptive management; 2) addressing outputs of multiple ecosystem goods and services and determining whether they are synergistic or competitive; and 3) integrating experimental and experiential knowledge and observations into decision making. Increasing the utility of models for rangeland management remains a key frontier and a major research need for the modeling community and will be achieved less by further technical advances and model complexity and more by the use of existing topoedaphic databases, the capacity to readily incorporate new experimental and experiential knowledge, and the use of frameworks that facilitate outcome-based, adaptive decision making at the enterprise level with associated economic considerations. Opportunities exist for increasing the utility of models for decision making and adaptive rangeland management through better matching of model complexity with enterprise-level, decision-making goals. This could be accomplished by incorporating a fundamental understanding of herbivory, fire, and spatiotemporal interactions with weather patterns that affect multiple ecosystem functions. Most important, effective models would allow land managers in a changing and variable climate to 1) evaluate trade offs in producing multiple goods and services, 2) optimize the application of conservation practices spatially (comparing costs and benefits accrued across different timescales), and 3) incorporate manager capacity, including experience, skills, and labor input.Original Abstract: Se ha producido un gran numero de mecanismos empiricos, modelos de simulacion y herramientas para apoyar la toma de decisiones para los pastizales. En conjunto, estos modelos han incrementado considerablemente nuestro conocimiento fundamental y entendimiento de la dinamica de la funcion de los procesos y estructura de los ecosistemas. Exploramos tres areas donde los modelos para el manejo de pastizales son regularmente un reto para los manejadores de pastizales y los niveles de toma de decisiones en las empresas: 1) en conjunto con espacio-tiempo y variabilidad climatica en la prediccion de escenarios, evaluacion de riesgos y la implementacion de manejo adaptativo, 2) enfocandose a las de salidas de multiples bienes y servicios de los ecosistemas, y si estos son sinergicos o compiten entre si, e 3) integracion del conocimiento experimental y experiencial y observaciones dentro de la toma de decisiones. Incrementar la utilidad de modelos para el manejo de pastizales permanece como una frontera clave y una necesidad e investigacion muy importante para modelar la comunidad, y se lograra mediante nuevos avances tecnicos y menos complejidad de los modelos y mas aun mediante el uso de base de datos topoedaficos existentes, la capacidad para facilmente incorporar nuevos conocimientos experimentales y experienciales, y el uso de marcos de referencia que faciliten los resultados, la toma de decisiones adaptativa en los niveles empresariales con las consideraciones economicas asociadas. Existen oportunidades para incrementar la utilidad de los modelos en la toma de decisiones y en el manejo adaptativo de los pastizales mediante un mejor ajuste de la complejidad del modelo con nivel empresarial y las metas en la toma de decisiones. Esto puede hacerse mediante la incorporacion de un entendimiento fundamental de las actividades de los herbivoros, fuego e interacciones espacio- temporales con patrones climaticos para afectar las multiples funciones del ecosistema. Mas importante aun, modelos efectivos podrian permitir a los manejadores de tierra en un cambiante y variable clima a 1) evaluar las ventajas y desventajas en la produccion de multiples bienes y servicios, 2) espacialmente optimizar la aplicacion de practicas de conservacion (comparando los costos y beneficios acumulados atreves de diferentes escalas de tiempo), y 3) incorporar la capacidad de los administradores incluyendo experiencia, habilidades y mano de obra.

In addition to the resources that must be committed to colony maintenance, biological costs, including genetic drift and accidental colony loss, also can occur. Although alternatives do exist, their application to mosquitoes is limited. Mosquito cryopreservation remains elusive, and many important species lack a well-defined diapause. Previously, we demonstrated that cold storing nondiapausing mated adult females of the northern house mosquito, Culex pipiens L. resulted in a nearly four-fold increase in longevity when measured at the LT50, allowing for cold storage for up to 10 wk. In the current study, we used sugar feeding during cold storage to significantly improve cold storage longevity. At 6 degree C, the LT50 of cold stored females was 23 wk, and 100% mortality was not realized until 43 wk. Cold-stored females did exhibit reduced fecundity, but egg production returned to normal levels within two generations. These results suggest that cold storage without diapause induction is a viable option for Cx. pipiens, and with the addition of sugar feeding, a colony could be maintained with less than two generations per year.

Borkh.) and native black-fruited hawthorns (mostly Crataegus douglasii Lindl.) in central Washington, but little has been published on the abundance of the fly in this region. In this paper, the abundance of R. pomonella across different sites near apple-growing areas in central Washington is documented in order to assess the threat of the fly to commercial apple orchards. The fly was first detected on traps in Klickitat, Yakima, and Kittitas Counties in 1981, 1995, and 1997, respectively. From 1981-2010 in Kittitas and Yakima Counties, only 0 to 4.7% of traps on apple, crabapple, and hawthorn trees were positive for flies, whereas in Klickitat County, located farther from commercial apple orchards, 0 to 41.9% of traps were positive. In 2008, in Yakima County and Goldendale in Klickitat County, 7.8% of black-fruited hawthorn trees were infested, with 0 to 0.00054 larvae per fruit. In 2010, in Kittitas and Yakima Counties and Goldendale in Klickitat County, 25.0% of C. douglasii trees were infested, with 0.00042 to 0.00248 larvae per fruit. In 2010, in a remote forested area of Klickitat County far from commercial apple orchards, 94.7% of C. douglasii trees were infested, with 0.20813 larvae per fruit. Overall results suggest R. pomonella is unlikely to develop high populations rapidly near major commercial apple-growing areas in central Washington, including in black-fruited hawthorns, increasing chances it can be kept out of commercial orchards.

Kojic acid (KA) is one such compound. It is a natural by-product of fungal fermentation commonly employed by food and cosmetic industries. We show that KA greatly lowers minimum inhibitory (MIC) or fungicidal (MFC) concentrations of commercial medicinal and agricultural antifungal agents, amphotericin B (AMB) and strobilurin, respectively, against pathogenic yeasts and filamentous fungi. Assays using two mitogen-activated protein kinase (MAPK) mutants, i.e., sakA Delta , mpkC Delta , of Aspergillus fumigatus, an agent for human invasive aspergillosis, with hydrogen peroxide (H2O2) or AMB indicate such chemosensitizing activity of KA is most conceivably through disruption of fungal antioxidation systems. KA could be developed as a chemosensitizer to enhance efficacy of certain conventional antifungal drugs or fungicides.

There is strong evidence that climate change has contributed to the extent and severity of recent outbreaks. Scientists are interested in quantifying relationships between bark beetle population dynamics and trends in climate. Process models that simulate climate suitability for mountain pine beetle outbreaks have advanced our understanding of beetle population dynamics; however, there are few studies that have assessed their accuracy across multiple outbreaks or at larger spatial scales. This study used the observed number of trees killed by mountain pine beetles per square kilometer in Oregon and Washington, USA, over the past three decades to quantify and assess the influence of climate and weather variables on beetle activity over longer time periods and larger scales than previously studied. Influences of temperature and precipitation in addition to process model output variables were assessed at annual and climatological time scales. The statistical analysis showed that new attacks are more likely to occur at locations with climatological mean August temperatures > 15 degree C. After controlling for beetle pressure, the variables with the largest effect on the odds of an outbreak exceeding a certain size were minimum winter temperature (positive relationship) and drought conditions in current and previous years. Precipitation levels in the year prior to the outbreak had a positive effect, possibly an indication of the influence of this driver on brood size. Two-year cumulative precipitation had a negative effect, a possible indication of the influence of drought on tree stress. Among the process model variables, cold tolerance was the strongest indicator of an outbreak increasing to epidemic size. A weather suitability index developed from the regression analysis indicated a 2.5X increase in the odds of outbreak at locations with highly suitable weather vs. locations with low suitability. The models were useful for estimating expected amounts of damage (total area with outbreaks) and for quantifying the contribution of climate to total damage. Overall, the results confirm the importance of climate and weather on the spatial expansion of bark beetle outbreaks over time.

Negative soil feedbacks may affect plant communities by suppressing dominant species, causing rarity of most plants, or reducing the competitive abilities of all species. Here, three soil feedback experiments were used to differentiate the effects of soil feedbacks on mid- to late-successional and semiarid grasslands. Then I tested whether the direction and degree of soil feedback accounts for variation in relative abundance among species that coexist within each plant community. Negative soil feedbacks predominated across all species and sites and were individually discernible for 40% of plant species. Negative soil feedbacks affected rare to dominant plant species. Negative soil feedbacks, capable of having negative frequency-dependent effects, have the potential to act as a fundamental driver of species coexistence.

Roast beef containing salt (NaCl; 1%, 1.5%, or 2%, w/w), blend of sodium pyro- and poly-phosphates (0.3%), and MoStatin LV1 (0%, 2%, or 2.5%) was inoculated with a 3-strain C. perfringens spore cocktail to achieve final spore population of 2.5 to 3.0 log CFU/g. The inoculated products were heat treated and cooled exponentially from 54.4 to 4.4 degree C within 6.5, 9, 12, 15, 18, or 21 h. Cooling of roast beef (2.0% NaCl) within 6.5 and 9 h resulted in 1.0 log CFU/g increase for cooling times longer than 9 h (1.1 and 2.2 log CFU/g, respectively). Incorporation of MoStatin LV1 into the roast beef formulation minimized the C. perfringens spore germination and outgrowth to <1.0 log CFU/g, regardless of the salt concentration and the cooling time. Practical Application: Cooked, ready-to-eat meat products should be cooled rapidly to reduce the risk of Clostridium perfringens spore germination and outgrowth. Meat processors are reducing the sodium chloride content of the processed meats as a consequence of the dietary recommendations. Sodium chloride reduces the risk of C. perfringens spore germination and outgrowth in meat products. Antimicrobials that contribute minimally to the sodium content of the product should be incorporated into processed meats to assure food safety. Buffered lemon juice and vinegar can be incorporated into meat product formulations to reduce the risk of C. perfringens spore germination and outgrowth during abusive cooling.

Plots were installed on the loosely consolidated, bare soil to measure sediment production, mulch cover, and plant regrowth. The experimental design was a repeated measures, randomized block on two soil types common in the northern Rocky Mountain area. The control produced the most sediment, while wood strands produced the least during the critical first winter following road decommissioning. Following the first year, there was no statistically significant difference in sediment production among the mulches or control. One year after the three mulches were applied, there was no statistical difference among mulch cover. Further, none of the mulches inhibited plant regrowth. The conservation implications of these research findings demonstrated that wood-based alternatives to agricultural straw were equally effective in reducing sediment production from originally bare, unvegetated soil strips resulting from forest road decommissioning. The amount of effective ground cover provided by mulch, plants, and litter appeared to be more important than the type of mulch.

The Texas Best Management Practice Evaluation Tool (TBET), which serves as an input/output interpreter and vastly simplified interface for the Soil and Water Assessment Tool (SWAT), was developed to predict mean annual runoff, sediment, nitrogen (N), and phosphorus (P) losses from agricultural fields in Texas under a variety of management scenarios and conservation practices. The Texas Best Management Practice Evaluation Tool was developed to provide a scientific basis for decision making, evaluation, and reporting in state and federal conservation programs. A rigorous, data-intensive calibration and validation process was employed in TBET development. First, hydrology outputs were calibrated with basin scale streamflow data from 20 US Geological Survey sites. Then, runoff, sediment, total N, and total P outputs were calibrated and validated with measured field scale data (260+ site years). Even without calibration, TBET was able to make "good" to "very good" predictions of mean annual runoff and total P losses according to commonly applied model evaluation methods. Calibrated TBET predictions of sediment and total N losses were not as accurate but were still "satisfactory." These much-improved results relative to those of often applied tools such as P Indices are very encouraging since the design goals of simple operation and accurate predictions for diverse Texas conditions with only readily available inputs were certainly met. Thus, TBET meets an important need by providing accurate, science-based estimates of conservation practice benefits at the field scale.

Recently, physically based Hooghoudt and Kirkham tile drain equations were incorporated into the Soil and Water Assessment Tool (SWAT) model (herein referred to as Modified SWAT) as alternative tile flow simulation methods and a tool to design cost-effective and environment-friendly tile drain water management systems. The goal of this study was to determine a range of values for the new tile drain parameters and to use measured streamflow data from the South Fork Watershed (SFW) in Iowa to evaluate the capability of the Modified SWAT to simulate water balance components for this tile-drained watershed. This was accomplished by reviewing literature of tile drainage studies and by comparing measured streamflow with that predicted by the Modified SWAT using the Nash-Sutcliffe efficiency (NSE) and percent bias (PBIAS [%]) statistical methods in addition to hydrographs. During the calibration period, the Modified SWAT simulated streamflow very well (monthly NSE = 0.85 and PBIAS = plus or minus 2.3%). During the validation period, the Modified SWAT model simulated streamflow well (monthly NSE = 0.70 and PBIAS = plus or minus 2.5%). Simulated water balance results indicated that the soil water with tile drainage (260 mm [10 in]) was significantly (p-value = 0.00) lower than soil water without tile drainage (355 mm [14 in]), while streamflow with (205 mm [8 in]) tile drainage was significantly (p-value = 0.03) greater than streamflow without (128 mm [5 in]) tile drainage. This shows that the Hooghoudt steady-state and Kirkham tile drain equations are potential alternative tile flow simulation methods and tile drainage design tools in SWAT.

The field-measured data were used to calibrate the Root Zone Water Quality Model (RZWQM), and the results were summarized in a special issue of Geoderma (Ahuja and Hatfield 2007). With a comprehensive, long-term measured dataset and a model that simulates many of the components of the agricultural system, one can begin to understand the effects of management practices on N loading, crop yields, and net income to the farmers. Other researchers can use this dataset to assess the effects of management on similar tile-drained systems occurring some distance from Nashua, under alternative climates and soils, with other management systems, or with simulation models using different process representations. By integrating the understanding developed at Nashua with datasets from other highly monitored sites and other sources, progress can be made in addressing problems related to excessive N fluxes in the Mississippi Basin. An example 30-year RZWQM simulation of 18 management systems implies that significant management changes are needed to meet the goal of reducing N loads to the Gulf of Mexico by 45%. This paper and the associated datasets are intended to be used in conjunction with the analyses and process descriptions presented in the Geoderma special issue.

But the practice is essentially untested in Midwest United States conditions and its water quality and crop yield benefits uncertain. This paper reports results from applying DWM to a 22 ha (54 ac) production field in central Iowa as part of a five-state Conservation Innovative Grant effort to document the impact of DWM across the Midwest. Three of nine plots in an existing tile drainage research site were retrofitted with control structures so that the drainage level could be controlled. Water flow from the tile in each plot, NO sub(3) concentration in the drainage, and crop yield were measured over a four year period from 2006 to 2009. The field was in a two year corn (Zea mays L.)-soybean (Glycine max [L.] Merr.) rotation with nitrogen (N) fertilizer applied before the corn crop only. During four years of monitoring tile flow, there was a significant (p = 0.05) 21% decrease in tile flow, no significant decrease in NO sub(3) concentration, and a significant 29% reduction in NO sub(3) load leaching from the DWM treatment compared to conventional drainage. No yield benefits from DWM were observed for the two year average for corn (2006 and 2008), but a significant yield increase of 8% was observed for the two year average for soybean (2007 and 2009). For the four years monitored in this study, it is unclear if the yield increase for soybean versus no increase for corn was due to weather patterns or because corn and soybean responded differently to the raised water table caused by DWM.

Although plants contain numerous genes coding for CADs, only one or two CADs appear to have a primary physiological role in lignin biosynthesis. Much of this distinction appears to reside in a few key residues that permit reasonable catalytic rates on monolignal substrates. Here, several mutant proteins were generated using switchgrass wild type (WT) PviCAD1 as a template to understand the role of some of these key residues, including a proton shuttling HL duo in the active site. Mutated proteins displayed lowered or limited activity on cinnamylaldehydes and exhibited altered kinetic properties compared to the WT enzyme, suggesting that key residues important for efficient catalysis had been identified. We have also shown that a sorghum ortholog containing EW, instead of HL in its active site, displayed negligible activity against monolignals. These results indicate that lignifying CADs require a specific set of key residues for efficient activity against monolignals.

Efficient recovery and enumeration of E. coliO157:H7 (Ec) and Pseudomonas fluorescens from produce are crucial for efficacy of biocontrol of Ec. Biocontrol refers to the suppression, reduction or control of one organism with another. P. fluorescens (Pf) is used for biocontrol research due to its colonization potential and suppressive activity against many microbes. We evaluated the sensitivity and selectivity of Restaino and Frampton (R & F) E. coliO157:H7 chromogenic medium (RFCM) and the effect of storage time and temperature on recovery of Ec and Pf from cultures and spinach. Ec and Pf were inoculated at the same level. Microbial counts differed between media and Ec was identified on RFCM based on color (blue-black precipitate), while Pf had distinct white/translucent colonies that fluoresce under ultraviolet light. Bacterial populations from mixed cultures plated on media and recovered ranged from 3.6-8.7 and 4.2-7.7 log cfu/mL for Ec and Pf, respectively. Microbial counts on spinach ranged from 6.0-8.2 and 6.5-8.6 log cfu/g for the above bacteria. Bacterial recovery increased with storage time of 0-48 h, implying a possible increase of contact time for bacterial attachment. The RFCM was best suited for simultaneous recovery of Ec and Pf based on differentiation of colonies on media and can be an effective tool for biocontrol research. Efficient recovery and accurate enumeration of Escherichia coliO157:H7, the human pathogen and Pseudomonas fluorescens, the biocontrol agent, from leafy greens are crucial for assessment of biocontrol efficacy. P. fluorescens has been used for biocontrol of some foodborne and plant pathogenic microbes from leafy greens, phyllosphere and rhizosphere of agronomic crops based on its competitive and antagonistic ability. Other than the generation of antibiotic resistant strains (foodborne pathogens) or use of green fluorescent-labeled mutants, there are limited options available for simultaneous recovery and enumeration of biocontrol and pathogenic bacteria. This research provides information on the recovery and differentiation of E. coliO157:H7 and P. fluorescens from media and inoculated spinach. The potential implication is a methodology for evaluation of the effectiveness of a biocontrol agent, with applications to other leafy greens. Accurate recovery and enumeration of biocontrol and pathogenic bacteria would promote optimal determination of biocontrol efficacy, a component of postharvest intervention strategy. This study validates the use of selective medium with specific applications for this type of research.

(Basidiomycotina, Hydanaceae), commonly regarded as a wood decay fungus, was consistently isolated from bareroot nursery Pinus banksiana Lamb. seedlings. S. brinkmannii was found in ectomycorrhizae formed by Thelephora terrestris Ehrh., Laccaria laccata (Scop.) Cooke, and Suillus luteus (L.) Roussel. In pure culture combinations with sterile P. banksiana and Populus tremuloides Michx. seedlings, S. brinkmannii colonized root cortical cells while not killing seedlings. Colonization by S. brinkmannii appeared to be intracellular but typical endo- or ectomycorrhizae were not formed. The fungus did not decay roots, although it was shown to produce cellulase in enzyme tests. Results suggest a unique association between S. brinkmannii and seedling roots that is neither mycorrhizal nor detrimental; its exact function remains to be elucidated.

While the majority of comparisons between central and marginal populations have revealed a general central-marginal (C-M) decline in genetic diversity, others show no clear pattern. Similarly, most latitudinal studies (although much fewer, especially those conducted rangewide) also showed latitudinal trends in genetic variation. To date, the C-M and latitudinal patterns have often been examined independently and have rarely been considered together when accounting for the observed genetic variation across species ranges. Here, in the light of the most recent findings, I show how latitude might be responsible for some of the deviations from the general C-M trends in genetic diversity, and vice versa. In the future, integrating latitude and range geometry with climate-induced species migration would offer important insights into conservation prioritization across species ranges.

Sequence analyses showed a putative Lip gene product (314 amino acids, a.a.) with its catalytic active site (Ser sub(111), Asp sub(258), and His sub(280)) identified. The foldase lif gene that is located 55 bp downstream of lip codes for a putative Lif (345 a.a.). To verify the biological function of the cloned lip gene for lipase expression in P. resinovorans, we constructed a lip knock-out mutant (lip::Tn5) by transposon insertion. Complementation of the lip knock-out P. resinovorans mutant with a lipase expression plasmid (pBS29-P2-lip) was performed, and its effect on lipase expression was investigated. The wild-type P. resinovorans and the lip::Tn5[pBS29-P2-lip ] recombinant (but not the lip::Tn5 mutant) showed fluorescence on rhodamine B plates indicative of lipase activity. The wild type exhibited extracellular lipase activity when grown on medium containing triacylglycerol substrates (tallow, olive oil, and tributyrin) as sole carbon sources, but the lip::Tn5 mutant did not show such activity. Lipase activity of various strains was also confirmed by TLC analysis of the composition of acylglycerols and free fatty acid in the extracts of the spent culture medium. We further found that tributyrin was more effective than olive oil in inducing lipase expression in P. resinovorans.

We examined zoospore concentration and exposure time needed to infect six Quercus (oak) species and the inoculum produced from their roots. Sprouted acorns, exposed to zoospores (3,000/ml) for different times and transplanted to potting soil, were susceptible to infection within 1 h of exposure but root weights were not impacted after 4 weeks (P = 0.952). Roots of Quercus prinus seedlings, inoculated with sporangia, had 0.6 to 3.2% colonization of the total root mass after 5 months. Neither root lesions nor obvious root sloughing were observed. Inoculum threshold levels were tested by exposing radicles to varying zoospore concentrations for 24 h. Results showed that radicle infection occurred even at 1 zoospore/ml. To test inoculum production, roots were inoculated with sporangia and transplanted into pots. Periodically, samples of runoff were collected and plated on selective medium. Afterward, root segments were plated to calculate percent colonization. After 16 and 35 days, root colonization and inoculum production from oak was lower than that of Viburnum tinus, a positive control. This study shows that P. ramorum is able to infect sprouted oak acorns and produce secondary inoculum, which may be important epidemiologically.

Geospatial data analysis of digital elevation models (DEMs) can improve BMP placement by ensuring that BMPs intercept flow paths. Livestock heavy use areas and riparian buffers within 100 m of the stream were digitized using aerial photography of Spring Creek watershed (Pennsylvania, USA). Flow path lengths and stream entry points from heavy use areas, from all agricultural land uses, and from a random sample of points were calculated using 1, 10, and 30 m DEM resolutions. Euclidean distances identified the nearest stream entry point regardless of topography. Drainage areas for each streambank cell were evaluated using each DEM resolution. Topographic calculations differed significantly from Euclidean, with median differences of 14.3 m for flow path length and 24.1 m between stream entry points for the 10 m DEM. Existing buffers intercepted runoff from only 23 % of heavy use areas. Drainage areas ranged from one to hundreds of DEM cells. Any DEM is an arbitrary representation of a continuous surface; both resolution and processing method affect the suitability of such a representation for any given purpose. We found that 30 m DEMs did not provide reasonable flow path estimates at the scale of grazing agriculture in this region, while Pennsylvania 1 m DEMs were minimally smoothed during DEM preparation, resulting in erratic flow paths. The 10 m DEMs were the most suitable available DEM product, and should be used in conjunction with site visits for planning pasture BMP placement.

Temperature is expected to increase over all land surfaces in the future, yet we have a surprisingly poor understanding of how tropical forests will respond to this significant climatic change. Here we present a contemporary synthesis of the existing data and what they suggest about how tropical forests will respond to increasing temperatures. Our goals were to: (i) determine whether there is enough evidence to support the conclusion that increased temperature will affect tropical forest C balance; (ii) if there is sufficient evidence, determine what direction this effect will take; and, (iii) establish what steps should to be taken to resolve the uncertainties surrounding tropical forest responses to increasing temperatures. We approach these questions from a mass-balance perspective and therefore focus primarily on the effects of temperature on inputs and outputs of C, spanning microbial- to ecosystem-scale responses. We found that, while there is the strong potential for temperature to affect processes related to C cycling and storage in tropical forests, a notable lack of data combined with the physical, biological and chemical diversity of the forests themselves make it difficult to resolve this issue with certainty. We suggest a variety of experimental approaches that could help elucidate how tropical forests will respond to warming, including large-scale in situ manipulation experiments, longer term field experiments, the incorporation of a range of scales in the investigation of warming effects (both spatial and temporal), as well as the inclusion of a diversity of tropical forest sites. Finally, we highlight areas of tropical forest research where notably few data are available, including temperature effects on: nutrient cycling, heterotrophic versus autotrophic respiration, thermal acclimation versus substrate limitation of plant and microbial communities, below-ground C allocation, species composition (plant and microbial), and the hydraulic architecture of roots. Whether or not tropical forests will become a source or a sink of C in a warmer world remains highly uncertain. Given the importance of these ecosystems to the global C budget, resolving this uncertainty is a primary research priority.

At two locations, five plots of equivalent size and stand structure served as untreated controls. All plots had early- to mid-outbreak beetle populations (i.e. 7.1-29.2 attacked trees/ha). Verbenone was applied at 370 g/ha in both studies. Intercept traps baited with MPB aggregation pheromone were placed near the corners of each plot after the treatment in order to monitor beetle flight within the plots. Trap catches were collected at 7- to 14-day intervals, and assessments were made at the end of the season of stand structure, stand composition and MPB attack rate for the current and previous years.

The objectives of this study were to identify the extent and distribution of marginally productive cropland in the state of Iowa and to quantify the changes in SOC and relevant soil properties following tree planting. Methods: A geographic information system (GIS) analysis was used to identify 1.05 million ha of marginal cropland within the state. Soil samples were collected from four locations with (<51 yr-old) forest plantations and adjacent crop fields. Soil samples were analyzed for SOC, total nitrogen (TN), pH, cation exchange capacity (CEC), ammonium acetate-extractable K, Ca, Mg, and Na, and particle size. Results: The forested soils had 30.0 plus or minus 5.1 % (mean plus or minus standard error) more SOC than the tilled cropland. The average annual change in SOC following tree planting was estimated to be 0.56 plus or minus 0.05 Mg C ha super(-1) yr super(-1). Differences were observed in several soil properties but strong correlations with SOC content were only observed for bulk density and extractable Ca. Conclusions: These results indicate that within 5 decades of tree planting on former cropland or pasture there was consistently and significantly greater SOC in soil beneath the trees.

However, interactions between epiphytic microbes and arthropods are rarely considered as a factor that affects arthropod behaviors. Here, volatile emissions from an epiphytic fungus were investigated as semiochemical attractants for two eusocial wasps. The fungus Aureobasidium pullulans was isolated from apples, and the volatile compounds emitted by fungal colonies were quantified. The attractiveness of fungal colonies and fungal volatiles to social wasps (Vespula spp.) were experimentally tested in the field. Three important findings emerged: (1) traps baited with A. pullulans caught 2750 % more wasps on average than unbaited control traps; (2) the major headspace volatiles emitted by A. pullulans were 2-methyl-1-butanol, 3-methyl-1-butanol, and 2-phenylethyl alcohol; and (3) a synthetic blend of fungal volatiles attracted 4,933 % more wasps on average than unbaited controls. Wasps were most attracted to 2-methyl-1-butanol. The primary wasp species attracted to fungal volatiles were the western yellowjacket (Vespula pensylvanica) and the German yellowjacket (V. germanica), and both species externally vectored A. pullulans. This is the first study to link microbial volatile emissions with eusocial wasp behaviors, and these experiments indicate that volatile compounds emitted by an epiphytic fungus can be responsible for wasp attraction. This work implicates epiphytic microbes as important components in the community ecology of some eusocial hymenopterans, and fungal emissions may signal suitable nutrient sources to foraging wasps. Our experiments are suggestive of a potential symbiosis, but additional studies are needed to determine if eusocial wasp-fungal associations are widespread, and whether these associations are incidental, facultative, or obligate.

Although waste foundry sands (WFSs) are generally not hazardous in nature, relevant data is currently not available in Argentina. This study aimed to quantify metals in waste molding and core sands from foundries using a variety of metal-binder combinations. Metal concentrations in WFSs were compared to those in virgin silica sands (VSSs), surface soils and soil guidance levels. A total analysis for Ag, Al, Ba, Be, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Sb, Te, Tl, V, and Zn was conducted on 96 WFSs and 14 VSSs collected from 17 small and medium-sized foundries. The majority of WFSs analyzed, regardless of metal cast and binder type, contained metal concentrations similar to those found in VSSs and native soils. In several cases where alkyd urethane binder was used, Co and Pb concentrations were elevated in the waste sands. Elevated Cr, Mo, Ni, and Tl concentrations associated with VSSs should not be an issue since these metals are bound within the silica sand matrix. Because of the naturally low metal concentrations found in most WFSs examined in this study, they should not be considered hazardous waste, thus making them available for encapsulated and unencapsulated beneficial use applications.

However, relatively little is known about the efficacy of VFS in mitigating bacterial runoff from land-applied swine manure. A field lysimeter study was designed to evaluate the effect of surface soil hydrologic conditions and vegetation on the retention of swine manure-borne Escherichia coli and Salmonella under simulated rainfall conditions. Experimental plots (6.5 m x 3.9 m) were set on a 5% slope lysimeter with loamy topsoil, clay loam or loam subsoil and a controllable groundwater level. Three small flow-intercepting miniflumes were installed 4.5 m from the plot's top, while all remaining runoff was collected in a gutter at the bottom. Plots were divided into bare soil and grass vegetation and upper surface soil moisture before rainfall events was controlled by the subsurface groundwater level. Swine manure slurry inoculated with E. coli and Salmonella, and with added bromide tracer, was applied on the top of the plots and simultaneously initiated the simulated rainfall. Runoff was collected and analyzed every 5 min. No substantial differences between retention of E. coli and Salmonella were found. In initially wet soil surface conditions, there was limited infiltration both in bare and in vegetated plots; almost all bromide and about 30% of bacteria were recovered in runoff water. In initially dry soil surface conditions, there were substantial discrepancies between bare and vegetated plots. In bare plots, recoveries of runoff water, bromide and bacteria under dry conditions were comparable to wet conditions. However, in dry vegetated plots, from 50% to 75% of water was lost to infiltration, while bromide recoveries ranged from 14 to 36% and bacteria recovery was only 5%. Substantial intraplot heterogeneity was revealed by the data from miniflumes. GIS analysis of the plot microtopography showed that miniflumes located in the zones of flow convergence collected the majority of bacteria. Overall, the efficiency of VFS, with respect to the retention of swine manure bacteria, varied dramatically depending upon the hydrologic soil surface condition. Consequently, VFS recommendations should account for expected amounts of surface soil water saturation as well as the relative soil water storage capacity of the VFS.

Control strategies for CLS rely heavily on quinone outside inhibitor (Q sub(O)I) fungicides. Despite the dependence on Q sub(O)Is for disease control for more than a decade, a comprehensive survey of Q sub(O)I sensitivity has not occurred in the sugar beet growing regions of France or Italy. In 2010, we collected 866 C. beticola isolates from sugar beet growing regions in France and Italy and assessed their sensitivity to the Q sub(O)I fungicide pyraclostrobin using a spore germination assay. In total, 213 isolates were identified with EC sub(50) values greater than 1.0 mu g ml super(-1) to pyraclostrobin, all of which originated from Italy. To gain an understanding of the molecular basis of Q sub(O)I resistance, we cloned the full-length coding region of Cbcytb, which encodes the mitochondrial Q sub(O)I-target enzyme cytochrome b in C. beticola. Cbcytb is a 1,162-bp intron-free gene with obvious homology to other fungal cytb genes. Sequence analysis of Cbcytb was carried out in 32 Q sub(O)I-sensitive (1.0 mu g ml super(-1)) isolates. All tested Q sub(O)I-resistant isolates harboured a point mutation in Cbcytb at nucleotide position 428 that conferred an exchange from glycine to alanine at amino acid position 143 (G143A). A PCR assay developed to discriminate Q sub(O)I-sensitive and Q sub(O)I-resistant isolates based on the G143A mutation could detect and differentiate isolates down to approximately 25 pg of template DNA. Microsatellite analyses suggested that Q sub(O)I resistance emerged independently in multiple genotypic backgrounds at multiple locations. Our results indicate that Q sub(O)I resistance has developed in some C. beticola populations in Italy and monitoring the G143A mutation is essential for fungicide resistance management in this pathosystem.

20368258 AB - Agricultural production is under increasing pressure by global anthropogenic changes, including rising population, diversion of cereals to biofuels, increased protein demands and climatic extremes. Because of the immediate and dynamic nature of these changes, adaptation measures are urgently needed to ensure both the stability and continued increase of the global food supply. Although potential adaption options often consider regional or sectoral variations of existing risk management (e.g. earlier planting dates, choice of crop), there may be a global-centric strategy for increasing productivity. In spite of the recognition that atmospheric carbon dioxide (CO2) is an essential plant resource that has increased globally by approximately 25 per cent since 1959, efforts to increase the biological conversion of atmospheric CO2 to stimulate seed yield through crop selection is not generally recognized as an effective adaptation measure. In this review, we challenge that viewpoint through an assessment of existing studies on CO2 and intraspecific variability to illustrate the potential biological basis for differential plant response among crop lines and demonstrate that while technical hurdles remain, active selection and breeding for CO2 responsiveness among cereal varieties may provide one of the simplest and direct strategies for increasing global yields and maintaining food security with anthropogenic change.

In 2002 and 2003, tillage treatments were evaluated for effectiveness in increasing cotton yield when noninversion deep tillage was either performed annually or not. Tillage treatments included a nontilled control, a straight-legged subsoil shank with bedding, and strip tillage with each of the following: a straight-legged subsoil shank, a Paratill, and a Terra-Max. In 2003, treatments were split with half the plots tilled and half not. No-tillage treatment significantly reduced penetration resistances better than others. Tillage decreased penetration resistance and improved yield but differences were significant only half the time. Treatments not tilled in the second year did not have significantly reduced penetration resistance because of a lack of recompaction during a dry first growing season. Tilling the second year improved yield marginally. Producers need to decide whether to till after a dry year on a case-by-case basis.

In the USA, swine CAFO lagoon water is used for crop irrigation that is regulated by farm-specific nutrient management plans (NMPs). Implementation of stricter US environmental regulations in 2013 will set soil P limits; impacting land applications of manure and requiring revision of NMPs. Precise knowledge of lagoon water quality is needed for formulating NMPs, for understanding losses of N and C in ammonia and greenhouse gas emissions, and for understanding risks of environmental contamination by fecal bacteria, including zoonotic pathogens. In this study we determined year-round levels of nutrients and bacteria from swine CAFO lagoon water. Statistical analysis of data for pH, electrical conductivity (EC), inorganic and organic C, total N, water-soluble and total minerals (Ca, Cu, Fe, K, Mg, Mn, P, and Zn) and bacteria (Escherichia coli, enterococci, Clostridium perfringens, Campylobacter spp., Listeria spp., Salmonella spp., and staphylococci) showed that all differed significantly by dates of collection. During the irrigation season, levels of total N decreased by half and the N:P ratio changed from 9.7 to 2.8. Some seasonal differences were correlated with temperature. Total N and inorganic C increased below 19 degree C, and decreased above 19 degree C, consistent with summer increases in ammonia and greenhouse gas emissions. Water-soluble Cu, Fe, and Zn increased with higher summer temperatures while enterococci and zoonotic pathogens (Campylobacter, Listeria, and Salmonella) decreased. Although their populations changed seasonally, the zoonotic pathogens were present year-round. Increasing levels of E. coli were statistically correlated with increasing pH. Differences between depths were also found.

Given the widespread dispersal of this biological control agent and its many unknown consequences, this study examines a variety of ecohydrological effects of the beetle on a Tamarix invaded ecosystem in the Great Basin Desert, Nevada. Nearly four years of ecosystem carbon dioxide (CO2) and evapotranspiration (ET) fluxes, measured with an eddy covariance system, are examined in relation to normalized difference vegetation index (NDVI) from Landsat imagery and on the ground measures of leaf area index (LAI) with a light attenuation instrument. We predicted that successive years of beetle herbivory should result in a trajectory of reduced ET and reduced CO2 uptake. We found that three and a half years of beetle herbivory and the resulting defoliation events produced short-term decreases in ET and C uptake. However, total ET and C fluxes over multiple growing seasons were not affected in a clear directional trajectory of reduced ET loss and reduced CO2 uptake, perhaps due to variability in beetle density. LAI and NDVI were fairly well correlated with each other and NDVI was correlated with ET during the summer months, indicating that these measures are useful for detecting beetle damage to the canopy.

Although much is known about the mechanisms controlling this regionally pervasive practice of artificial drainage at the field-plot scale, an integrative assessment of the effect of drainage density (i.e., the number of tile drains per unit area) on the transport of nutrients and solutes in streams at the catchment scale is lacking. In this study, we quantified the flux and hydrological pathways of agricultural NO3- and road-salt Cl- from catchments lying within the Wabash River Basin, a major source of NO3- to the Mississippi River. The paired catchments differ primarily in drainage density (70% vs. 31%, by catchment area), with essentially all other agricultural management, land use, and soil drainage characteristics remaining equal. Our study revealed two significant hydrological responses to increased drainage density: (1) more near-surface storm event water (dilute in both NO3-andCl-) was transported early in the storm and (2) higher transport of Cl--laden pre-event soil water relative to shallow groundwater elevated in NO3- occurred later in the storm. These patterns are consistent with a proposed conceptual model in which increased drainage density results in (1) greater transport of soil water to streams and (2) a delayed rise in the water table. With respect to nutrient management implications, these results indicate that increased drainage density impacts subsurface pools of Cl- and NO3- differently, a finding that we propose is linked to soil/ground water dynamics in artificially drained agricultural catchments.

Vaccines require similar to 7 days to induce protection; thus, before this time, vaccinated animals are still susceptible to the disease. Our group has previously shown that swine inoculated with 1 x 10 super(11) focus forming units (FFU) of a replication-defective human adenovirus containing the gene for porcine interferon alpha (Adt-pIFN- alpha ) are sterilely protected from FMDV serotypes A24, O1 Manisa, or Asia 1 when the animals are challenged 1 day postadministration, and protection can last for 3-5 days. Polyriboinosinic-polyribocytidylic acid stabilized with poly-L-lysine and carboxymethyl cellulose (poly ICLC) is a synthetic double-stranded RNA that is a viral mimic and activates multiple innate immune pathways through interaction with toll-like receptor 3 and MDA-5. It is a potent inducer of IFNs. In this study, we initially examined the effect of poly IC and IFN- alpha on FMDV replication and gene induction in cell culture. Poly ICLC alone or combined with Adt-pIFN- alpha was then evaluated for its therapeutic efficacy in swine against intradermal challenge with FMDV A24, 1 day post-treatment. Groups of swine were subcutaneously inoculated either with poly ICLC alone (4 or 8 mg) or in combination with different doses of Adt-pIFN- alpha (2.5 x 10 super(9), 1 x 10 super(9), or 2.5 x 10 super(8) FFU). While different degrees of protection were achieved in all the treated animals, a dose of 8 mg of poly ICLC alone or combined with 1 x 10 super(9) FFU of Adt-pIFN- alpha was sufficient to sterilely protect swine when challenged 24 h later with FMDV A24. IFN-stimulated gene (ISG) expression in peripheral blood mononuclear cells at 1 day post-treatment was broader and higher in protected animals than in nonprotected animals. These data indicate that poly ICLC is a potent stimulator of IFN and ISGs in swine and at an adequate dose is sufficient to induce complete protection against FMD.

Floristic surveys had begun on these islands in 1901, and provided valuable information about earlier vascular plant composition. Three Mile Island, Hawk's Nest Island, and Blueberry Island were first sampled quantitatively in 1978, again in 1991, and most recently in 2001. The data compiled here are for woody vascular plant species found in long-term monitoring plots on the islands owned and/or managed by the Appalachian Mountain Club. Pinus resinosa, P. strobus, and Tsuga canadensis were the three most dominant species on Hawk's Nest throughout the study period. On Blueberry Island, Acer rubrum, Betula populifolia, and T. canadensis were the three most dominant woody species when sampling began. However, by 2001 Ilex verticillata, Myrica gale, and Vaccinium corymbosum were the three most dominant species. On Three Mile Island, P. strobus and Quercus rubra were the two most dominant species in 1978, but by 2001 A. pensylvanicum and Hamamelis virginiana were the dominants. Overall species richness within the permanent plots increased on Three Mile and Blueberry Islands, while the total number of species remained relatively constant on Hawk's Nest Island. JF - Rhodora.

To gain insight into the molecular mechanisms of pathogenesis a global approach based on analysis of expressed sequence tags (ESTs) was undertaken. To get broad gene-expression coverage, two normalized EST libraries were developed from mycelia grown under high nitrogen-induced virulent and low nitrogen/methylglucose-induced hypovirulent conditions. A pilot-scale assessment of gene diversity was made from the sequence analyses of the two libraries. A total of 2280 cDNA clones was sequenced that corresponded to 220 unique sequence sets or clusters (contigs) and 805 singlets, making up a total of 1025 unique genes identified from the two virulence-differentiated cDNA libraries. From the total sequences, 295 genes (38.7%) exhibited strong similarities with genes in public databases and were categorized into 11 functional groups. Approximately 61.3% of the R. solani ESTs have no apparent homologs in publicly available fungal genome databases and are considered unique genes. We have identified several cDNAs with potential roles in fungal pathogenicity, virulence, signal transduction, vegetative incompatibility and mating, drug resistance, lignin degradation, bioremediation and morphological differentiation. A codon-usage table has been formulated based on 14694 R. solani EST codons. Further analysis of ESTs might provide insights into virulence mechanisms of R. solani AG 4 as well as roles of these genes in development, saprophytic colonization and ecological adaptation of this important fungal plant pathogen.

CO sub(2) enrichment can alter grassland ecosystem function both directly and through indirect, soil-specific effects on moisture, nitrogen availability and plant species composition, potentially leading to threshold change in ecosystem properties. Here we show that the increase in aboveground net primary productivity (ANPP) with CO sub(2) enrichment depends strongly on soil type. We found that the ANPP-CO sub(2) response of grassland was 2.5 greater on two soils with higher plant-available soil moisture and where direct CO sub(2) effects on ANPP were accompanied by indirect CO sub(2) effects on ANPP mediated through an increase in soil moisture or increased dominance of a productive C sub(4) grass. Indirect CO sub(2) effects on ANPP were absent on a third soil that was less responsive to CO sub(2) (1.6). Unexpectedly, soil N availability changed little with CO sub(2) and did not seem to drive responses in ANPP. On the more responsive soils, the more productive grass C sub(4) was favoured with CO sub(2) enrichment because of greater photosynthetic efficiency. Our results enhance present models of the controls on ecosystem responses to CO sub(2) (refs , , ) and demonstrate mechanisms by which soils could cause spatial variation in CO sub(2) effects on ANPP and other ecosystem attributes.

Food insecurity increased in all residence areas with the 'Great Recession' beginning in 2007, with the greatest increase in suburbs. The Current Population Survey Food Security Supplement was used to examine the likelihood of food insecurity across residence areas. Net of income and other household characteristics, suburban households were more likely to be food insecure than nonmetropolitan households and as likely to be food insecure as principal city households. The results suggest that during the recession economic hardship spread increasingly to suburbs. Adapted from the source document.

Choices among food, physical activity, and television AN - 1458540637; 17160671 AB - Children's stress-coping behaviors and their determinants have not been widely studied. Some children eat more after stress and dietary restraint moderates stress eating in youth, but eating has been studied in isolation of other coping behaviors. Children may not choose to eat when stressed if other behavioral alternatives are available. The purpose was to determine individual difference factors that moderate the duration of stress coping choices and to determine if stress-induced eating in youth persists when other stress coping behaviors are available. Thirty children (8-12years) completed a speech stressor on one day and read magazines on another day. They completed a free-choice period with access to food, TV, and physical activity on both days. Dietary restraint moderated changes in time spent eating and energy consumed from the control to stress day. Children high in restraint increased their energy intake on the stress day. Changes in the time spent watching TV were moderated by usual TV time, as children higher in usual TV increased their TV time after stress. Thus, dietary restrained children eat more when stressed when other common stress coping behaviors are freely available. These results extend the external validity of laboratory studies of stress-induced eating.

The substrate layers of the sheets were prepared from poly(lactic acid) (PLA) and sugar beet pulp (SBP) or poly (butylene adipate-co-terephthalate (PBAT) and SBP by a twin-screw extruder. The active layer consisting of antimicrobial in either PLA or chitosan was formed on the surfaces of the substrates by solution coating followed by solvent evaporation. Air-coupled ultrasonic evaluation and microscopic examination showed a homogeneous structure for the composite sheets. Mechanical analysis and acoustic emission demonstrated the double-layered composites possessing appropriate tensile strength and fracture characteristics for the use as light weight-bearing materials. The release of Nisaplin super( registered ) or allyl isothiocyanate (AIT) effectively suppressed the growth of Listeria monocytogenes and Salmonella cells, respectively; the co-release of Nisaplin super( registered ) and AIT played a synergistic effect on inhibition of L. monocytogenes.

Sediment samples were collected at 10, 40, 100, 300, and 500 m from inflow 13 days prior to amendment and 1, 5, 12, 22, and 36 days post-amendment. Background pesticide concentrations ranged from <1 to 977, <1 to 119, and <1 to 2 mu g kg super(-1), for atrazine, S-metolachlor, and permethrin, respectively. Average post-amendment atrazine and S-metolachlor were 2,915-3,927 and 3-20 mu g kg super(-1), respectively at 10-40 m and 538-872 and <1 mu g kg super(-1), respectively at 300-500 m. Average post-amendment permethrin was 65-200 mu g kg super(-1) at 10-40 m and 1-10 mu g kg super(-1) at 300-500 m. H. azteca 10-day survival varied spatially and temporally up to 100 m from inflow. Animal growth, independent of survival, was reduced 40 and 100 m from inflow on day 36, showing continued sediment toxicity of up to 100 m from inflow more than 1 month after amendment. Animal survival and growth were unaffected at 300 and 500 m from inflow throughout the study period. Correlations of pesticide concentrations and H. azteca responses indicated that observed sediment toxicity was primarily from permethrin with potential additional synergistic toxicity from atrazine and methyl parathion. Study results indicate that natural backwater wetlands can be managed to ameliorate pesticide mixture 10-day sediment toxicity to H. azteca within 300 m of inflow and smaller wetlands ( less than or equal to 100 m) may require several months of effluent retention to mitigate effects.

Currently, determination of DOC in surface water is primarily accomplished by manually collecting samples for laboratory analysis, which requires at least 24 h. In other words, no effort has been devoted to monitoring real-time variations of DOC in a river due to the lack of suitable and/or cost-effective wireless sensors. However, when considering human health, carbon footprints, effects of urbanization, industry, and agriculture on water supply, timely DOC information may be critical. We have developed here a new paradigm of a dynamic data-driven application system (DDDAS) for estimating the real-time load of DOC into a river. This DDDAS was validated with field measurements prior to its applications. Results show that the real-time load of DOC in the river varied over a range from -13,143 to 29,248 kg/h at the selected site. The negative loads occurred because of the back flow in the estuarine reach of the river. The cumulative load of DOC in the river for the selected site at the end of the simulation (178 h) was about 1.2 tons. Our results support the utility of the DDDAS developed in this study for estimating the real-time variation of DOC in a river ecosystem.

We used an existing digital database of witness trees listed in deeds from 1752 to 1899 to compare characteristics of red spruce (Picea rubens Sarg.) sites to non-red spruce sites to gain an understanding of historical spruce-dominated forests in West Virginia. The analysis revealed that red spruce witness trees were found at significantly higher elevations than non-spruce witness trees across the study area. However, spruce witness trees in the Western Allegheny Mountains subsection were found at significantly lower elevations than non-spruce witness trees. Indicator species analysis determined red spruce to be associated with toe slopes, benches, and valleys, although most locations were on side slopes. Across the entire study area, red spruce witness trees were more likely to be found on northeastern aspects and on acidic and frigid soils of the Mandy series. Historically, red spruce was associated with American beech (Fagus grandifolia Ehrh.), birch (Betula L.), and hemlock (Tsuga canadensis (L.) Carriere). This information should be used to guide red spruce restoration efforts and shows that a range of ecological settings should be considered when setting goals and implementing active management.

Prions are composed solely of an aberrantly folded isoform (PrP super(Sc)) of a normal cellular protein (PrP super(C)). Shared sequence identity of PrP super(Sc) with PrP super(C) has limited the detection sensitivity of immunochemical assays, as antibodies specific for the disease-causing PrP super(Sc) isoform have not been developed. Here we report the generation of three new monoclonal antibodies (MAbs) to PrP, which were isolated following immunization of Prnp super(0/0) Balb/cJ mice with highly purified PrP super(Sc) isolated from brain lipid rafts. Epitope mapping using synthetic PrP peptides revealed that the three MAbs bind different epitopes of PrP. The DRM1-31 MAb has a conformational epitope at the proposed binding site for the putative prion conversion co-factor "protein X." The DRM1-60 MAb binds a single linear epitope localized to the beta 2- alpha 2 loop region of PrP, whereas DRM2-118 binds an epitope that includes sequences within the octarepeat region and near the site of N-terminal truncation of PrP super(Sc) by proteinase K. Our novel anti-PrP MAbs with defined PrP epitopes may be useful in deciphering the conformational conversion of PrP super(C) into PrP super(Sc).

We collected faecal samples from nine spotted hyaenas (Crocuta crocuta), 15 lions (Panthera leo) and 13 African wild dog (Lycaon pictus) from Luangwa Valley, Zambia. The most common gastrointestinal parasites found were Isospora spp., Spirometra sp., Taeniidae and Sarcosystis spp. Twenty-eight per cent of all samples were co-infected with Spirometra sp. and Taeniidae, with co-infection rates highest among lions (67%). Thirty-three per cent (3/9) of spotted hyaenas were infected with Isospora sp. Ninety-two per cent (12/13) of wild dog were infected with Sarcocystis, similar to results from studies in South Africa. One lion was infected with a parasite whose morphology suggested Strongyloides sp., not previously been reported in lions. Samples from one lion and two spotted hyaenas yielded no gastrointestinal parasites. Overall, parasite species were consistent with those found from studies in other regions of Africa and are likely a result of ingesting infected prey. To our knowledge this study provides the most comprehensive survey of gastrointestinal parasite infection in large carnivores from this region of Africa to date and provides baseline data for future studies.

The AOTF-based hyperspectral microscope imaging system can be effective for characterizing spectral properties of biofilms formed by Salmonella enteritidis as well as Escherichia coli. The intensity of spectral images and the pattern of intensity distribution of spectra varied with system parameters (integration time as well as gain) of the HMI system. Preliminary results demonstrated that determination of optimum parameter values of the HMI system and the integration time, which must be no more than 250 ms, are important for quality image acquisition from biofilms formed by S. enteritidis. Among the 89 contiguous spectral images between 450 and 800 nm, the intensity of images at 458, 494, 522, 550, 574, 590, and 670 nm were distinctive for biofilm of S. enteritidis, whereas the intensity of spectral images at 546 nm was distinctive for E. coli with dark-field illumination with a metal hal-ide light source. For more accurate comparison of intensity from spectral images, a calibration protocol of quantitative intensity comparison needs to be developed to standardize image acquisition using neutral-density filters and multiple exposures. For the identification or classification of unknown foodborne pathogen samples, ground truth region-of-interest pixels need to be selected for "spectrally pure fingerprints" from various foodborne pathogens such as E. coli and Salmonella species.

In these experiments, swine waste slurry was circulated through silicone hosing located in an aeration tank, the hose allowing for the passage of small molecules such as methane and malodors. The aeration tank employed a minimal growth medium and chopped silicone to absorb potentially toxic compounds that might slow bacterial growth. Malodors were reduced in treatments. Methane and carbon dioxide were also reduced, especially in the case of carbon dioxide, where concentrations were reduced by almost 80%. The net result of this was methane comprising about 90% of the biogas, as compared to only 70% of the biogas produced by controls. This was due to more bicarbonate buffering in treated slurries, resulting in higher slurry pH. In experiments in which the silicone rubber was omitted from aeration tanks, malodors were still removed efficiently. While carbon dioxide in treated slurry biogas was again greatly reduced, methane concentrations were not. At the end of the experiment control biogas consisted of 75% methane, while in treated biogas methane comprised 95%. In control and treated slurries, Clostridia spp. and Bacteroides spp. comprised over 50% of the total population. Clone sequences from bacterial populations in the aeration tanks grouped with the Proteobacteria and Actinobacteria, two microbial groups with representatives often associated with bio-degradation and bioremediation.

The resulting anaerobic conditions in saturated soils may lead to increased denitrification and gaseous N(2)O release. Sugarcane was grown in lysimeters using four water table treatments, ranging from 40 to 16 cm in depth. Gas emissions were measured in April, July, and September using a photoacoustic gas analyzer. Denitrification enzyme activity (DEA) was performed on soil samples from the upper 15 cm, including non-limiting carbon and nitrogen conditions. No differences in N(2)O emissions or DEA were observed between water table treatments. However, emissions of N(2)O were higher in the spring, and CO(2) emissions were greater in the late summer. Overall, incomplete DEA was very low in the soil samples, indicating that shallow water tables will not increase N(2)O emissions in these organic soils. Additions of C versus NO(3) increased DEA, indicating that these organic soils are carbon limited. Neither the amoA nor nosZ genes were affected by water table management, but the abundance of the nosZ gene increased from April to September, while amoA gene abundance decreased.

This study evaluates whether a statistical downscaling method is fully applicable to generate daily precipitation under non-stationary conditions in a wide range of climatic zones. Ten stations were selected from polar to tropical climates around the world. The measured data were split into calibration and validation periods in such a way that the difference of the mean annual precipitation between the two periods was maximized. Transition probabilities of wet-following-wet (P(w/w)) and wet-following-dry (P(w/d)) days generally increased linearly with an increase in mean monthly precipitation for all calendar months and locations in all climatic zones. The transition probabilities of the validation periods, interpolated with linear regressions, agreed well with those directly calculated from the observed data of the periods, with model efficiency ranging from 0.786 to 0.966. Due to good estimation of P(w/w) and P(w/d), generated frequency distributions of dry and wet spell lengths agreed reasonably well with the measured distributions for the validation period. Overall, statistics of the downscaled daily and monthly precipitation amounts, annual maximum daily amounts, and dry and wet spells were similar to those of the measured data for stations whose skewness coefficients were not greater than 3.5, suggesting that caution be exercised when generating daily precipitation with the Pearson type III distribution if the skewness coefficient is greater than 3.5. This downscaling method can be easily used with the two-parameter gamma distribution for daily precipitation to circumvent the skewness issue, if necessary. This study has demonstrated that the downscaling method can generate proper daily precipitation series for climates having non-stationary changes.

On-site drainage water filter treatment systems can potentially prevent the release of agricultural contaminants into adjacent waterways. A recently developed porous iron composite (PIC) product may have promise as a filter material for drainage water treatment. Therefore, a laboratory study was initiated to evaluate the feasibility of using PIC for this purpose. Laboratory experiments included saturated falling-head hydraulic conductivity tests, contaminant (nutrient/pesticide) removal batch tests, and saturated solute transport column tests. The saturated falling-head hydraulic conductivity tests indicate that the original PIC product by itself has a high enough hydraulic conductivity (>0.001 cm s(-1)) to make this material hydraulically practical for filter treatment use. PIC hydraulic conductivity can be further enhanced (>0.01 cm s(-1)) by utilizing only the portion of this material retained on a 100 mesh sieve (particle size > 0.15 mm). Batch test results carried out with spiked drainage water and either unsieved or 100 mesh sieved PIC showed nitrate reductions of greater than 30%, and 100% removal of the pesticide atrazine. Saturated solute transport column tests with spiked drainage water provided more insight on the effectiveness and efficiency of utilizing PIC for drainage water filter treatment. These column tests confirm that PIC is capable of nearly complete removal of atrazine, and significant nitrate reduction. Additionally, once the phosphate originally present within the PIC material is leached out, the PIC then exhibited ability to remove large quantities of phosphate. Consequently, these laboratory findings support employment of PIC for use within on-site agricultural drainage water filter treatment systems.

Process-based, convective-dispersive modeling of microbial transport through preferential flow has been conducted. Likewise, regression modeling has been used to study solute transport (e.g., nitrate) under agricultural systems and can have advantages over process-based modeling, such as fewer or easier to determine parameters and easier determination of confidence intervals. However, empirical models (e.g., regression) have only rarely been used to investigate microbial transport. In addition, the selection of time response curves to empirically model simple, right skewed, single breakthrough events from field or laboratory data is generally an arbitrary choice and often considers only conventional distribution-shaped response curves, such as lognormal distributions. In this study, we evaluate four rational polynomial functions for modeling bromide and E. coli data from a single breakthrough event from a tile-drained field near Nashua, Iowa. Bromide and liquid swine manure were applied to the plot immediately prior to 42 mm of overhead sprinkler irrigation. E. coli and bromide concentrations were determined in subsurface drainage water samples collected for the next 24 h. Nonlinear iteratively re-weighted least squares regression procedures were used to model the breakthrough data. The maximum event value, time of occurrence, and event total were estimated from the parameters for each model. Selection of the best model was based on multiple performance criteria. A simple rational polynomial with a linear factor in the numerator and quadratic form in the denominator was the overall best choice for E. coli (R(2)= 0.92). A related fractional order form also known as the Gunary model was the best choice for bromide (R(2)= 0.93). In comparison, the more commonly assumed lognormal distribution described only 78% of the variation in E. coli and 68% of the variation in bromide, with a weighted mean square error 3.0 to 4.6 times larger than each selected rational polynomial model. In this experiment, the chosen models clearly tracked E. coli and bromide distribution better than the lognormal model.

We hypothesize that increased conversion efficiency of fertilizer to crop yield resulted from changes in fertilizer management in Central and Eastern European countries. Efficient nutrient management depends on fertilizer applied, management practices, and weather, which impact uptake, utilization efficiency, and crop yield. Trends in fertilizer consumption and wheat yields from 1986 to 2005 were studied for five countries. There were significant differences in yield gap, defined as the difference between potential and actual yields. Partial factor productivity of applied nitrogen fertilizer (N) is calculated from real and modified indices. A predictive metric is introduced based on the quantity of unworked, or nonproductive, N (N sub(uw)). Sustainable cropping practices reduce N sub(uw) and yield gap. Improved knowledge of crop responses to balanced plant nutrition at the country level contribute to improved agricultural and environmental policies and enhance production sustainability.

This shift is commonly used as the indicator of ecosystem "harm" in studies developing empirical critical levels (CLE) for ammonia (NH sub(3)) and critical loads (CLO) for N. To be most effective, empirical CLE and/or CLO must firmly link lichen response to causal pollutant(s), which is difficult to accomplish in field studies in part because the high cost of N measurements limits their use. For this case study we synthesized an unprecedented array of atmospheric N measurements across 22 long-term monitoring sites in the Los Angeles Basin, California, USA: gas concentrations of NH sub(3), nitric acid (HNO sub(3)), nitrogen dioxide, and ozone (n = 10 sites); N deposition in throughfall (n = 8 sites); modeled estimates of eight different forms of N (n = 22 sites); and nitrate deposition accumulated on oak twigs (n = 22 sites). We sampled lichens on black oak (Quercus kelloggii Newb.), and scored plots using two indices of eutroph (N tolerant species) abundance to characterize the community-level response to N. Our results contradict two common assertions about the lichen-N response: (1) that eutrophs respond specifically to NH sub(3) and (2) that the response necessarily depends upon the increased pH of lichen substrates. Eutroph abundance related significantly but weakly to NH sub(3) (r super(2) = 0.48). Total N deposition as measured in canopy throughfall was by far the best predictor of eutroph abundance (r super(2) = 0.94), indicating that eutrophs respond to multiple forms of N. Most N variables had significant correlations to eutroph abundance (r super(2) = 0.36-0.62) as well as to each other (r super(2) = 0.61-0.98), demonstrating the risk of mistaken causality in CLE/CLO field studies that lack sufficient calibration data. Our data furthermore suggest that eutroph abundance is primarily driven by N inputs, not substrate pH, at least at the high-pH values found in the basin (4.8-6.1). Eutroph abundance correlated negatively with trunk bark pH (r super(2) = 0.43), exactly the opposite of virtually all previous studies of eutroph behavior. This correlation probably results because HNO sub(3) dominates N deposition in our study region.

However, preliminary attempts to commercially ferment the cucumbers in the presence of oxygen led to the development of a secondary cucumber fermentation or spoilage. The development of cucumber secondary fermentation has also been occasionally reported by processors using cover brine solutions containing sodium chloride. This study focused on the development of a model system to characterize CaCl2 and NaCl secondary cucumber fermentations under conditions similar to those present on the commercial scale. Cucumber fruits mixed with cover brine solutions, containing 100 mM CaCl2 or 1.03 M NaCl, and 25 mM acetic acid, were fermented in 2 L fermentation vessels subjected to air-purging at a rate of 5 mL/min. Microorganisms and selected biochemical changes detected in the experimental cucumber fermentations had been previously observed in commercial spoilage samples, suggesting the successful reproduction of the secondary fermentation in the laboratory. Experimental secondary fermentations were characterized by the rapid oxidation of the lactic acid produced during the primary fermentation, which, in turn, increased pH. Lactic acid disappearance seemed to be the result of yeast metabolism that also led to the chemical reduction of the environment to levels at which other bacteria could become established and produce butyric, propionic, and acetic acids. This model system will be applied for the identification of strategies to prevent the initiation of the cucumber secondary fermentation and reduce economic losses in the pickling industry. Practical Application: The study of secondary cucumber fermentation has represented a challenge for many years. The successful development of a model system for the study of this phenomenon in the laboratory is instrumental in furthering the study of the event and in optimizing the sodium-chloride-free fermentation at the commercial scale.

Identifying source areas, quantifying contributions, and evaluating management practices are required to address current and future water quality concerns. A before-after study was conducted from 2003-2010 on a sub-watershed of Northland Country Club Golf Course in Duluth, MN to demonstrate the impacts of two different phosphorus management approaches (Period 1: traditional application and timing using commercially available synthetic blends; Period 2: reduced rate, low dose applications, and organic formulations). Outflow median dissolved reactive phosphorus (DRP) and total phosphorus (TP) stream concentrations were significantly less in Period 2 compared to Period 1. There was no statistical difference in the mean TP loading in Period 1 (0.25 kg ha super(-1) year super(-1)) compared to Period 2 (0.20 kg ha super(-1) year super(-1)) or between the DRP loading in Period 1 (0.15 kg ha super(-1) year super(-1)) compared to Period 2 (0.09 kg ha super(-1) year super(-1)). However, by switching to organic phosphorus formulations and reducing application rates by greater than 75%, substantial reduction in DRP and TP concentrations was achieved. Based on these findings it is recommended that turf managers (parks and recreation to golf courses) explore the feasibility of altering their fertility management related to phosphorus by including organic formulations, low dose applications, and overall rate reductions. Additionally, it is recommended that the fertilizer industry develop and make more readily available commercial blends with lesser to zero amounts of phosphorus.

H. Gross; family: Polygonaceae) is an exotic annual barbed vine that has invaded the northeastern USA and Oregon (2). In July of 2010, in a search for potential biological control pathogens (3), diseased P. perfoliata plants were found along the Firtina River near Ardesen, Turkey. Symptoms were irregular dark necrotic lesions along leaf margins and smaller irregular reddish lesions on the lamellae of leaves. Symptomatic leaves were sent to the quarantine facility of FDWSRU, USDA, ARS in Ft. Detrick, MD, for pathogen isolation and testing. Symptomatic leaves were excised, surface disinfested in 0.615% NaOCl, and then incubated for 2 to 3 days in sterile moist chambers at 20 to 25 degree C. Numerous waxy sub-epidermal acervuli with 84- mu m-Iong (mean) black setae were observed in all of the lesions after 2 to 3 days of incubation. Conidiophores within acervuli were simple, short, and erect. Conidia were one-celled, hyaline, guttulate, subcylindrical, straight, 12.3 to 18.9 x 3.0 to 4.6 mu m (mean 14.3 x 3.7 mu m). Pure cultures were obtained by transferring conidia onto 20% V-8 juice agar. Appressoria, formed 24 h after placing conidia on dialysis membrane over V-8 juice agar, were smooth, clavate. aseptate. regular in outline, and 6.4 to 10.0 x 5.1 to 7.2 mu m (mean 7.5 x 6.6 mu m). These characters conformed to the description of Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. (1). A voucher specimen was deposited in the U.S. National Fungus Collections (BPI 882461). Nucleotide sequences for the internal transcribed spacers (ITS 1 and 2), directly sequenced from ITS 1 and ITS 4 standard primers (4), were deposited in GenBank (JN887693). A comparison of these sequences with ITS 1 and 2 sequences of the C. gloeosporioides epitype IMI 356878 (GenBank EU 371022) (1) using BLAST found 479 of 482 identities with no gaps. Conidia from 14-day-old cultures, in an aqueous suspension of 1.0 x 10 super(6) conidia ml super(-1), were spray-inoculated onto healthy stems and leaves of twenty 30-day-old P. perfoliata plants. Another 10 plants were not inoculated. All plants were placed in a dew chamber at 25 degree C for 16 h with no lighting. They were then placed in a 20 to 25 degree C greenhouse with a 14-h photoperiod. Light was generated using 400W sodium vapor lights. Lesions developed on leaves and stems of all inoculated plants after 7 days, and symptoms were the same as observed in the field. Each plant was rated weekly for disease severity on a 0 to 10 rating scale where 0 = no disease symptoms and 10 = 100% symptomatic tissue. After 28 days, the average disease rating of inoculated plants was 3.95 plus or minus 0.94. No disease developed on noninoculated plants. C. gloeosporioides was reisolated from all inoculated plants. Host range tests will determine the potential of this isolate as a biological control agent for P. perfoliata. To our knowledge, this is the first report of anthracnose caused by C. gloeosporioides on P. perfoliata.

When seed were germinated and grown in the presence of A. tumefaciens, in the absence of wounding. 94% of the seedlings exhibited tumors while 89% contained systemic A. tumefaciens populations. When seedlings were wound inoculated. A. tumefaciens established endophytic populations in stem tissue and often migrated from the site of infection. Distribution of A. tumefaciens in the stem was random and may exhibit seasonal variation. A. tumefaciens populations in root tissue were more readily detected than in stem tissue and may serve as a reservoir for subsequent infection of the aerial portions of the tree. Importantly. 7% of inoculated, asymptomatic seedlings contained endophytic populations of A. tumefaciens. In all. 17% of seedlings inoculated as seeds developed galls at secondary stem-wound sites. These results provide an ecological and epidemiological foundation upon which to modify existing tree-handling practices in both nursery and orchard production environments to manage crown gall incidence.

Percentage adults emerging from pupae and percentage adult females that escaped soil, fabric, and paper mulches over a soil or sand substrate ranged from 63 to 83, and 40-53%, respectively. Percentage adults emerging from pupae and percentage adult females that walked through the open interior of 1.52-6.10-m horizontal pipes of 1.5-2.0-cm inner diameter ranged from 57 to 81, and 27-61%, respectively. Percentage adults emerging from pupae that escaped through sand depths of 2.5-10.2, and 12.7-20.3 cm, ranged from 68 to 87, and 12-88%; and percentage adult females that escaped ranged from 46 to 58, and 38-70%, respectively. In 15.4-cm-inner-diameter pipes filled with different heights of sand, the highest percentage of the total number of adults that emerged in the control were found from 0 to 20.3 cm, and ranged from 37 to 71%. Ten to 47% of adults were found from 20.3 cm to below the surface, and 6-21% escaped to the top of 20.3-50.8 cm high sand columns. In column heights of 55.9 and 61 cm, pressures at the bottom caused by the weight of the sand above were 91.4 and 99.7 g/cm2, respectively, and a mean of <1 adult escaped to the top. Before pupation, the late third instars were found to travel continuously for 6.9 h over 23.9 m at a speed of 6.0 cm per min, when placed on a smooth surface, at 22.2 degree C. Teneral females and males that could not fly, made approximately 7 stops totaling 11-13 min, walked at a speed of 57-62 cm per min, and began a rest period of 83-84 min duration, at 85-89 min before flight. Males walked a distance of 13.1 m in 22 min, which was greater than females that walked for 9.6 m in 17 min, at 20-22 degree C and 35% RH. The mobility of the third instars and the teneral adults is discussed in relation to potential control techniques in olive orchards.

The disease is caused by the xylem-limited bacterium Xylella fastidiosa, which is transmitted by several species of sharpshooters. The objectives of this research were to elucidate the fate of bacteria in planta after inoculations in almond nursery plants and to determine patterns of insect vector population dynamics and temporal distribution of X. fastidiosa-infected plants relative to host plant assemblages in habitats surrounding commercial nurseries. In an experimental nursery, disease incidence was markedly affected by rootstock type. Prior to bud grafting, 'Nemaguard' rootstock seedlings were not susceptible to bacterial infection. After bud grafting with a susceptible scion ('Sonora'), scions were susceptible to infection regardless of rootstock genotype. Surveys near commercial nurseries revealed that only habitats with permanent grass cover sustained vector populations throughout the season. A total of 87 plant samples tested positive for X. fastidiosa (6.3%) using enzyme-linked immunosorbent assay (ELISA), with a higher number of X. fastidiosa-infected plants found in weedy alfalfa fields than in other habitat types. Among plant species infected by X. fastidiosa. 33% were winter annuals, 45% were biennials or perennials, and 22% were summer annuals. Collectively, these findings identified a potential pathway for X. fastidiosa infection of almonds in nursery situations.

In observations taken over the winter months, S. filum was found naturally colonizing 2% of P. graminis subsp. graminicola uredinia on first-year plantings and 25% of the uredinia on second-year plantings of perennial ryegrass. In controlled experiments conducted in glasshouses and growth chambers, S. filum applied to rust-inoculated plants reduced the lifetime spore production of P. graminis subsp. graminicola pustules by half, from 39,000 to 18,000 spores/pustule. Mist duration, temperature, and P. graminis subsp. graminicola pustule age at the time of S. filum inoculation had significant effects on the proportion of P. graminis subsp. graminicola pustules infected by S. filum. Fifty percent of all P. graminis subsp. graminicola pustules were infected when S. filum was inoculated onto erumpent pustules and incubated above 5 degree C for 48 h while exposed to mist. Plants inoculated with both fungi under controlled conditions and then planted into the field had a significantly greater proportion of P. graminis subsp. graminicola pustules infected with S. filum, and a significantly reduced P. graminis subsp. graminicola overwintering population, compared with plants inoculated with P. graminis subsp. graminicola only. First-year stands of perennial ryegrass treated in the field with monthly applications of S. filum had more than 10 times the proportion of pustules infected with S. filum and 50% less P. graminis subsp. graminicola disease compared with the nontreated controls. In comparison, plants with one application of fungicide during the winter had 98% lower P. graminis subsp. graminicola severity than the P. graminis subsp. graminicola-only control There were no effects of S. filum or fungicide application on rust severity in 2- or 3-year-old perennial ryegrass stands.

Despite the lack of effective alternatives, solarization is rarely used in cotton because of its high cost. Use of solarization might be increased if soil temperatures could be used to predict reductions in pathogen inoculum levels, thereby ensuring high levels of efficacy. However, relationships between survival of race 4 chlamydospores, soil moisture, and temperatures typical of solarized soil are not known. Survival of culture- and plant-produced chlamydospores of race 4, incubated at 40 degree C in dry or moist environments, indicated the importance of moisture in determining spore survival. Mortality of spores from either source was low under dry conditions and much higher under moist conditions. A 6-week exposure of culture-produced chlamydospores to temperatures from 30 to 40 degree C under moist conditions indicated limited mortality at temperatures less than or equal to 35 degree C. However, most spores were eliminated by day 6 at 40 degree C. A second study using a moist environment indicated high mortality of spores by 5 weeks at 37 degree C or by 10 days at temperatures from 39 to 41 degree C. These results should serve as useful guides in efforts to develop solarization protocols that maximize effectiveness based on monitored soil temperatures.

Less recognized, but equally important to inhabitants of these affected regions, is an increasing susceptibility to rainfall-induced debris flows and their associated impacts. The same high rainfall rates that sustain tropical forest cover can often serve as the triggering mechanism for debris flows. The natural rate of debris flow occurrence on steep slopes subject to episodic, intense rainfall is dependent on the stabilizing effect of tropical forests. Either loss or significant reduction in forest cover can weaken this natural defense. Information from postdisaster observations and research on the November 1988 storm event in southern Thailand provides a case study illustrating the potential impacts of increased debris flow susceptibility resulting from conversion of forest cover to rubber tree crops. Development resulting in the loss of tropical forest cover may be accompanied by local increase in population, property development, and infrastructure. Consequently, the potentially disastrous consequences of increased debris flow occurrence are amplified by the greater vulnerability of local populations. Preserving the tropical forest cover is an obvious and often difficult means of retaining this natural protection. Effective policy should capitalize on the values of tropical forests as part of the strategy for retaining adequate forest cover. Policy should also seek to avoid creating pressures that foster forest removal or their conversion to other types of land cover in steep terrain. Areas where tropical forests were converted to other cover types can be restored to secondary forests to avoid a permanent state of increased debris flow susceptibility. Restoration of secondary tropical forests can successfully re-establish the forest characteristics that limit debris flow occurrence. Experience in Central America and the Caribbean demonstrates that successful restoration is possible but requires a significant commitment of both time and resources. In addition to the cost and technical difficulties involved, the increased susceptibility to debris flow occurrence persists through many years until successful restoration is achieved. Both retention of existing tropical forests and restoration of forest cover where loss has occurred are often justified by the reduced risk of debris flow impacts to vulnerable populations and infrastructure.

In an attempt to contain the spread of this noxious weed the South African authorities have supported the introduction of host-specific and damaging seed-feeding biocontrol agents. In order to increase seed losses caused by existing agents, surveys were undertaken in Argentina and a seed-feeding weevil Coelocephalapion gandolfoi Kissinger (Coleoptera: Brentidae: Apioninae) identified. Aspects of the biology and the host range of this seed-feeding weevil were studied in Argentina and South Africa to evaluate its potential as a biocontrol agent. The period from oviposition to adult emergence was c. 40 days. The duration of the stages was: 11-20 days for eggs, 25-40 days for larvae, and 6-16 days for pupae. Field surveys found that the beetle was responsible for 51 % of the seed damage on P. flexuosa. The host range of C. gandolfoi was restricted to Prosopis species in the section Algarobia. Oviposition and feeding preference for Prosopis species native to Argentina and P. glandulosa from North America was very high. We consider C. gandolfoi to be a good candidate for the biological control of invasive Prosopis species in South Africa.

Despite its ecologic and economic impacts, the fundamental molecular mechanisms of the host immune response to this pathogen remain unclear. While F. columnare can induce marked pathologic changes in numerous ectopic tissues, the adhesion of F. columnare to the gill in particular is strongly associated with pathogen virulence and host susceptibility. Recently, in this regard, using RNA-seq expression profiling we found that a rhamnose-binding lectin (RBL) was dramatically upregulated in the gill of fish infected with F. columnare (as compared to naive fish). Thus, in the present study we sought to further characterize and understand the RBL response in channel catfish (Ictalurus punctatus). We first identified two distinct catfish families with differential susceptibilities to columnaris disease; one family was found to be completely resistant while the other was susceptible (0% mortality versus 18.3% respectively, P 120-fold; P< 0.05) in fish fasted for 7 d (as compared to fish fed to satiation daily), yet expression levels returned to those of satiated fish within 4 h after re-feeding. Collectively, these findings highlight putative roles for RBL in the context of columnaris disease and reveal new aspects linking RBL regulation to feed availability.

In this study, we applied 11 microsatellite loci and Bayesian analyses to investigate genetic diversity and population structure in marsh frogs (Pelophylax ridibundus) living in two types of environment-highly fragmented urban landscapes, and landscapes characterized by the presence of a river and artificial canals. Our results show reduced genetic diversity, lower effective population sizes, and higher genetic differentiation for spatially isolated urban populations in comparison with populations outside intensely urbanized areas. Reduction of allelic diversity in urban localities isolated for 13-37 generations is more conspicuous than reduction of expected heterozygosity. Populations living close to the River Danube, its branches, and artificial canals are genetically more homogenous. Our results also suggest that the Danube in Bratislava is not a natural barrier to gene flow. In contrast, it acts as a natural corridor for water frog dispersal. Population structure of P. ridibundus also shows higher genetic connectivity within water paths than between them, suggesting limited overland dispersal, and reflects the historical landscape structure associated with the distribution of the lost river branches.

In addition to supporting the production of seasonal snowmelt-driven streamflow forecasts, this long-term dataset is widely used throughout the research community to study historical climatic change impacts. Therefore it is critical to understand what factors may affect the quality of the measurements, especially if those non-climatic factors possess long-term trends. For example, the snowpack measurement dates are nominally the first and fifteenth of the month although they actually average approximately 2 days earlier. This study found that the variability of measurement dates are determined by, 1) the epoch of the measurement, 2) the day of the week of the nominal measurement date, 3) the presence or absence of snow at the site and 4) if the measurement is for the first or the fifteenth of the month. The measurement date is less variable if snow is absent from the site. Mid-month data are collected closer to the nominal measurement date, and first of month data have a greater early bias. Since 1957, there has been a stronger aversion to collecting data on Fridays and weekends. Measurements are taken today on average 1.35 days earlier than they were before 1957. The effect on measurement bias depended on the time of year and was generally less than 5 % of the measurement. Therefore, changes in measurement date only slightly mask one's ability to accurately detect long-term climatic trends.

On the average, 23% of adults observed on mature leaves were killed by H. citriformis. These dead psyllids were characterized as being mummified and covered to various extents by synnemata produced by the fungus. Mummified cadavers were most abundant on citrus leaves during the fall and winter months, with the maximal percentage of mummified psyllids sometimes exceeding 75% of the total number of adults observed. Mummified cadavers were nearly absent each spring, presumably because relative humidity levels were suboptimal for the fungus at this time. Based on dispersion analyses, a monitoring plan for mummified cadavers would best include multiple samples in individual trees as well as multiple tree samples throughout a grove. Mummified cadavers with synnemata, which serve as point sources for new infections of the fungus in psyllids, were observed to remain on leaves for a mean of 68 days (one cadaver remained on a leaf for 168 days). Rainfall was positively correlated with the number of days mummies remained on leaves while mean daily air temperature was negatively correlated. Mummified cadavers were abundant in the summer during 2006 but not during 2007. This may have been a density-dependent consequence of low psyllid host populations in the grove in 2007. Alternatively, combination sprays of oil and copper applied during 2007 may have suppressed the fungus. This latter possibility prompted a laboratory investigation into the toxicity to H. citriformis of six chemicals commonly used in citrus. Copper hydroxide, petroleum oil, and elemental sulfur at maximum label rates each significantly reduced the infectivity of a laboratory culture of H. citriformis while copper sulfate pentahydrate, aluminum tris and alpha-keto/humic acids did not. This finding indicates that citrus growers interested in capitalizing on H. citriformis as a biological control agent of D. citri should avoid applying high rates of copper hydroxide, oil or sulfur.

Analysis of 26 polymorphic amplified fragment length polymorphism (AFLP) markers generated with three primer-pair combinations indicated a moderate average gene diversity () of 0.283. Genotypic diversity was high in all collection areas with the exception of a paddy in Itasca County. Significant population subdivision by collection site was found with amova tests using both the entire fungal population data (FST=0.29, P<0.001) and the clone-corrected data (FST=0.08, P<0.001), and with a Markov chain Monte Carlo approach. Abundant immigrants, shared haplotypes and admixed genotypes were found in paddies in central-eastern areas. Although indirect tests did not support the hypothesis of random mating at the subpopulation level, sexual recombination nevertheless may be possible in areas where both mating type idiomorphs, MAT1-1 and MAT1-2, were found. These results may have implications in breeding for resistance and disease management.

The pathogen is dispersed in rain splash and spread is promoted by wind. The goal of this study was to gain some insight into the properties of short-distance splash dispersal of Xcc from similar to 1.5m-tall cankered grapefruit canopies in turbulent wind, common during rainstorms in Florida. Turbulent wind up to 19.9m s-1 was tested in five experiments. Bacteria flux density (BFD, bacteria cm-2 min-1) was quantified at heights of 30, 70, 110, 130 and 180cm above ground, and at four horizontal points (17, 51, 85 and 119cm) at each height across the direction of the wind 1m downwind. BFD varied among experiments, but the lowest BFDs were consistently detected at the greatest sample height. Despite differences between experiments, the relationship between log BFD and sample height was consistently described by a linear function (P=0.06-0.99). The BFD collected at the horizontal points across the wind path was variable. BFDs collected were sometimes significantly different, but no relationship was discernible.

Expansion of economic capability, infrastructure, and residential capacity requires significant investment, and so efforts to limit the negative effect of landslides and other natural hazards on these investments are crucial. Many of the newer approaches to identifying and mapping relative landslide susceptibility within a developing area are hindered by insufficient data in the places where it is most needed. An approach called matrix assessment was specifically designed for regional development planning where data may be limited. Its application produces a landslide-susceptibility map suitable for use with other planning data in a Geographical Information System (GIS) environment. Its development also encourages collecting basic landslide inventory data suitable for site-specific studies and for refining landslide hazard assessments in the future. This paper illustrates how matrix assessment methodology was applied to produce a landslide-susceptibility map for the Commonwealth of Dominica, an island nation in the eastern Caribbean, and how with a follow up study the relative landslide-susceptibility mapping was validated. A second Caribbean application on Jamaica demonstrates how this methodology can be applied in a more geologically complex setting. A validated approach to mapping landslide susceptibility which does not require extensive input data offers a significant benefit to planning in lesser developed parts of the world.

Native Americans began diverting water to irrigate agricultural crops in the floodplain in the 14th century. The Spanish followed and increased agricultural irrigation to over 125 000 acres. Frequent flooding of the MRG valley in the 19th century led to many engineering projects in the early 20th century to control flooding. A series of impoundment dams, diversion dams, and levees were constructed. The loss of floodplain habitats throughout the MRG Valley has altered the riparian community and caused the demise of many fish species. A controlled flood pulse from Cochiti Reservoir, New Mexico was initiated in April 2005 to support the recovery of the endangered Rio Grande silvery minnow, Hybognathus amarus. This study documents habitat selection by larval fishes in a restored floodplain in the Rio Grande, NM. Larval fish light traps captured 394 larvae representing four cyprinid species (Pimephales promelas, H. amarus, Cyprinella lutrensis and Cyprinus carpio). Results for CCA indicate that Hybognathus amarus prefer shallow, low velocity habitats. Results from Chao-Jaccard similarity index indicated that relative contribution was highest in P. promelas at 64% followed by H. amarus 33%. Results from (dis)similarity analysis reveal that species composition between habitat orientation and date was highest in H. amarus at 42% followed by P. promelas 40%. Cyprinella lutrensis and C. carpio represented 9.5 and 8.5%, respectively. A general linear model indicated that only depth and velocity were significantly different (p=0.02 and p=0.03 respectively).

For medfly, a mutant-based sexing system is available as well as a transgenic system where a tetracycline-suppressible (Tet-off) toxic molecule is female-specifically produced. However, the former classical genetic system took many years to refine, and the latter system results in female death by a poorly understood mechanism, primarily in the pupal stage after rearing costs have been incurred. Here we describe a Tet-off transgenic embryonic sexing system (TESS) for Anastrepha suspensa that uses a driver construct having the promoter from the embryo-specific A. suspensa serendipity alpha gene, linked to the Tet-transactivator. This was used to drive the expression of a phospho-mutated variant of the pro-apoptotic cell death gene, Alhid, from Anastrepha ludens. The system uses a sex-specific intron splicing cassette linked to a cell death gene lethal effector. Progeny from TESS strains heterozygous for the transgene combination were 80-100% males, whereas four double homozygous TESS strains had 100% male-only progeny, with female death limited primarily to embryogenesis. In a large-scale test, more than 30,000 eggs from two strains resulted in 100% male-only progeny. The transgenic sexing approach described here is highly effective and cost-efficient by eliminating most, if not all, female insects early in embryogenesis using a well-characterized apoptotic mechanism.

AN - 1041140828; 22209007 AB - Inflammation associated with obesity may play a role in colorectal carcinogenesis, but the underlying mechanism remains unclear. This study investigated whether the Wnt pathway, an intracellular signaling cascade that plays a critical role in colorectal carcinogenesis, is activated by obesity-induced elevation of the inflammatory cytokine tumor necrosis factor-alpha (TNF-α). Animal studies were conducted on C57BL/6 mice, and obesity was induced by utilizing a high-fat diet (60% kcal). An inflammation-specific microarray was performed, and results were confirmed with real-time polymerase chain reaction. The array revealed that diet-induced obesity increased the expression of TNF-α in the colon by 72% (P=.004) and that of interleukin-18 by 41% (P=.023). The concentration of colonic TNF-α protein, determined by ex vivo culture assay, was nearly doubled in the obese animals (P=.002). The phosphorylation of glycogen synthase kinase 3 beta (GSK3β), an important intermediary inhibitor of Wnt signaling and a potential target of TNF-α, was quantitated by immunohistochemistry. The inactivated (phosphorylated) form of GSK3β was elevated in the colonic mucosa of obese mice (P<.02). Moreover, β-catenin, the key effector of canonical Wnt signaling, was elevated in the colons of obese mice (P<.05), as was the expression of a downstream target gene, c-myc (P<.05). These data demonstrate that diet-induced obesity produces an elevation in colonic TNF-α and instigates a number of alterations of key components within the Wnt signaling pathway that are protransformational in nature. Thus, these observations offer evidence for a biologically plausible avenue, the Wnt pathway, by which obesity increases the risk of colorectal cancer. Copyright © 2012 Elsevier Inc.

AN - 1039882356; 22674812 AB - Ants often compete with other ants for resources. Although formic acid is a common defensive chemical of formicine ants, it does not occur in any other subfamilies in Formicidae. No information on toxicity of formic acid to red imported fire ants, Solenopsis invicta, is available. This study examined its contact and fumigation toxicity to S. invicta in the laboratory. In a contact toxicity bioassay, 24 h LD50 values of formic acid for workers ranged from 124.54 to 197.71 µg ant(-1) . Female alates and queens were much less sensitive to formic acid than workers. At a concentration of 271.72 µg ant(-1) , which killed 81.09 ± 16.04% of workers, the 24 h mortality was up to 39.64% for female alates and 38.89% for queens. In fumigation bioassays, 24 h LC50 values ranged from 0.26 to 0.50 µg mL(-1) for workers, 0.32 µg mL(-1) for male alates and 0.70 µg mL(-1) for female alates. Complete mortality (100%) in queens occurred 24 h after they had been exposed to 1.57 µg mL(-1) of formic acid. At a concentration of 2.09 µg mL(-1) , KT50 values ranged from 23.03 to 43.85 min for workers, from 37.84 to 58.37 min for male alates, from 86.06 to 121.05 min for female alates and from 68.00 to 85.92 min for queens. When applied topically, formic acid was significantly less toxic than bifenthrin to red imported fire ants. Although its fumigation toxicity was lower than that of dichlorvos, formic acid had about an order of magnitude higher toxicity to S. invicta than to other insects studied so far. It may be worth investigating the use of formic acid for managing imported fire ants. This article is a US Government work and is in the public domain in the USA.

(Lepidoptera: Noctuidae). AN - 1038228120; 22824002 AB - Midgut trypsins are associated with Bt protoxin activation and toxin degradation. Proteinase inhibitors have potential insecticidal toxicity against a wide range of insect species. This study was conducted to evaluate the interaction of proteinase inhibitors with Bt toxin and to examine midgut trypsin gene profile of Heliothis virescens. A sublethal dose (15 ppb) of Cry1Ac, 0.75% soybean trypsin inhibitor, and 0.1% and 0.2% N-α-tosyl-L-lysine chloromethyl ketone significantly suppressed midgut proteinase activities, and resulted in reductions in larval and pupal size and mass. The treatment with inhibitor+Bt suppressed approximately 65% more larval body mass and 21% more enzymatic activities than the inhibitor-only or Bt-only. Eleven trypsin-like cDNAs were sequenced from the midgut of H. virescens. All trypsins contained three catalytic center residues (H(73), D(153), and S(231)), substrate specificity determinant residues (D(225), G(250), and G(261)), and six cysteines for disulfide bridges. These putative trypsins were separated into three distinct groups, indicating the diverse proteinases evolved in this polyphagous insect. These results indicated that the insecticidal activity of proteinase inhibitors may be used to enhance Bt toxicity and delay resistance development. Published by Elsevier Inc.

AN - 1031158650; 22699106 AB - Numerous plant species worldwide including Palicourea marcgravii and Tanaecium bilabiatum in Brazil cause sudden death and are known to contain monofluoroacetate (MFA). Other species in Brazil including some species traditionally assigned to Mascagnia but now properly called Amorimia species and other Palicourea species are reported to cause sudden death in livestock and are suspected to contain MFA due to the similarity of clinical signs. In this study, an HPLC-APCI-MS method to detect and quantify MFA was developed and was used to investigate plant material from field collections and/or herbarium specimens of Mascagnia, Amorimia, and Palicourea species suspected of causing sudden death. MFA was detected in Amorimia amazonica, Amorimia camporum, Amorimia exotropica, Amorimia pubiflora, Amorimia rigida, and Amorimia septentrionalis as well as Palicourea aeneofusca. MFA concentrations differ greatly between Palicourea species and Amorimia species, which may explain the incidence of poisoning and the amount of plant material required to cause sudden death between these taxa.

These factors included the abundance of other plant species, changes in water depth, water quality, and herbivory by insects. Abiotic factors like temperature, pH, DO, and conductivity varied among sites and, more importantly, over time. The same was true for S. minima biomass, coverage, and condition. Principal component analysis identified four components which together explained 64% of the variability in S. minima biomass. The first component correlated strongly with herbivory from Cyrtobagous salviniae Calder and Sands and Synclita obliteralis (Walker) as well as the abundance of the duckweed Spirodela polyrrhiza (L.) Schleid. Temperature effects were strongly represented in the second principal component. A stepwise regression model that best predicted S. minima biomass incorporated conductivity, insect herbivory, and interspecific plant abundance. Broader dry vs. wet season influences were apparent and linked to temperature, water depth, and conductivity that covaried with S. minima biomass. Sites where water depth changed the most had the least S. minima. Insect herbivory did not increase under more stagnant conditions when plant populations were less mobile. Overall, S. minima populations cycled in southern Florida in response to a shifting array of abiotic and biotic factors. The relative importance of these factors was less clear although the influences of herbivory, temperature, and the presence of other plants were significant.

Examined modeling strategies range from a simple antecedent precipitation index to the application of modern land surface models (LSMs) based on complex water and energy balance formulations. A quasi-global evaluation of lagged VI/soil moisture cross-correlation suggests, when globally averaged across the entire annual cycle, soil moisture estimates obtained from complex LSMs provide little added skill (< 5% in relative terms) in anticipating variations in vegetation condition relative to a simplified water accounting procedure based solely on observed precipitation. However, larger amounts of added skill (5-15% in relative terms) can be identified when focusing exclusively on the extra-tropical growing season and/or utilizing soil moisture values acquired by averaging across a multi-model ensemble.

16816829 AB - Long-term (more than 15 years) effects of elevated CO2 on belowground responses of trees have received limited attention in the literature. We report on a study in which sour orange trees (Citrus aurantium L.) grown in an Avondale loam in Phoenix, AZ, were exposed to ambient and elevated (ambient+300 mu molmol-1) levels of atmospheric CO2 for 17 years. At study termination, soil cores were collected to determine how long-term CO2 enrichment affected horizontal (0.5, 1.0, 1.5, and 2.0m from each tree) and vertical (0-105cm in 15cm increments) standing crop fine root dry weight and length. Overall, elevated CO2 increased both root length (35.6%) and root dry weight (39.1%) densities. There was no effect of CO2 concentration on horizontal root distribution patterns. However, significant CO2 by depth interactions were noted for both root length and root dry weight densities with differences occurring only in the top two depths. Elevated CO2 increased fine root length density by 64.5 and 57.2% at the 0-15 and 15-30cm depths. Respective increases for root dry weight were 80.3 and 82.8%. These large responses occurred under water and nutrient supplies typical of orchard conditions and suggest that long-term citrus productivity can be enhanced under future levels of atmospheric CO2.

AN - 1033153648; 22480773 AB - Type II heat-labile enterotoxins (LT-II) have been reported in Escherichia coli isolates from humans, animals, food and water samples. The goal here was to determine the specific roles of the antigenically distinguishable LT-IIa and LT-IIb subtypes in pathogenesis and virulence of enterotoxigenic E. coli (ETEC) which has not been previously reported. The prevalence of genes encoding for LT-II was determined by colony blot hybridization in a collection of 1648 E. coli isolates from calves and pigs with diarrhea or other diseases and from healthy animals. Only five isolates hybridized with the LT-II probe and none of these isolates contained genes for other enterotoxins or adhesins associated with porcine or bovine ETEC. Ligated intestinal loops in calves, pigs, and rabbits were used to determine the potential of purified LT-IIa and LT-IIb to cause intestinal secretion. LT-IIa and LT-IIb caused significant secretion in the intestinal loops in calves but not in the intestinal loops of rabbits or pigs. In contrast, neonatal pigs inoculated with isogenic adherent E. coli containing the cloned genes for LT-I, LT-IIa or LT-IIb developed severe watery diarrhea with weight loss that was significantly greater than pigs inoculated with the adherent, non-toxigenic parental or vector only control strains. The results demonstrate that the incidence of LT-II appeared to be very low in porcine and bovine E. coli. However, a potential role for these enterotoxins in E. coli-mediated diarrhea in animals was confirmed because purified LT-IIa and LT-IIb caused fluid secretion in bovine intestinal loops and adherent isogenic strains containing cloned genes encoding for LT-IIa or LT-IIb caused severe diarrhea in neonatal pigs.

Here we examined the interaction of E. coli O157:H7 (EcO157) with spinach leaf indigenous microorganisms during co-colonization and establishment of a mixed biofilm on a stainless steel surface. Stainless steel surface was selected to mimic the surface of produce-processing equipment, where retention of foodborne pathogens such as EcO157 could serve as a potential source for transmission. We observed a positive effect of spinach-associated microbes on the initial attachment of EcO157, but an antagonistic effect on the EcO157 population at the later stage of biofilm formation. Metagenomic analyses of the biofilm community with the GeoChip revealed an extremely diverse community (gene richness, 23409; Shannon-Weiner index H, 9.55). Presence of EcO157 in the mixed biofilm resulted in a significant decrease in the community alpha -diversity (t test, P<0.05), indicating a putative competition between the pathogen and indigenous spinach microbes. The decrease in the beta -diversity of the EcO157-inoculated biofilm at 48 h (ANOVA, P<0.05) suggested a convergent shift in functional composition in response to EcO157 invasion. The success of EcO157 in the mixed biofilm is likely associated with its metabolic potential in utilizing spinach nutrients: the generation time of EcO157 in spinach lysates at 28 degree C is similar to 38 min, which is comparable to that in rich broth. The significant decrease in the abundance of many genes involved in carbon, nitrogen, and phosphorus cycling in the EcO157-inoculated biofilms (t test, P<0.05) further support our conclusion that competition for essential macronutrients is likely the primary interaction between the EcO157 and indigenous spinach-biofilm species.

Variability in precipitation is also an important control on snowpack accumulation and, therefore, on timing of meltwater inputs. We evaluate the correlation of total area burned and area burned severely to snowmelt-induced streamflow timing and total annual streamflow metrics across the Pacific Northwest region from 1984-2005. Principal component scores on total annual water year flow and date of 50th percentile flow (PC1T) in the Pacific Northwest were used as predictors of satellite-inferred area burned and area burned severely in forested settings. Both annual area burned and burned severely are significantly correlated with mean annual flow and streamflow timing. PC1T alone explains 24% of the variability in annual area burned. Path analysis suggests that a substantial amount of the variability in annual area burned, previously attributed solely to temperature effects on melt timing, may be primarily driven by trends in precipitation and total annual streamflow. Principal component analysis scores on mean annual streamflow explain as much as 46% of the variability in annual area burned from 1984-2005. Thus, although streamflow timing may be a better single correlate of annual wildfire activity, timing is, in turn, strongly dependent on precipitation. These results suggest that recent fire activity in forests of this region are influenced more by precipitation variability than temperature-induced shifts in snowmelt timing, with significant implications for our ability to predict wildfire activity in the future.

A sophisticated dual-permeability transport model was modified and a theory was developed to mechanistically account for the transport, retention, and release of colloids with transients in IS. In particular, colloid release in the model was directly related to the balance of applied hydrodynamic and resisting adhesive torques that determined the fraction of the solid surface area that contributed to colloid immobilization (S sub(f)). The colloid sticking efficiency ( alpha ) and S sub(f) were explicit functions of IS that determined the rates of colloid interaction with the solid, immobilization on the solid, colloid release from the solid and back into the bulk aqueous phase, and the maximum amount of colloid retention. The developed model was used to analyze experimental transport and release data with transients in IS for 1.1 and 0.11 mu m latex microspheres, E. coli D21g, and coliphage X174. Comparison of experimental values of S sub(f)(IS) with predictions based on mean interaction energies indicated that predictions needed to account for the influence of physical and/or chemical heterogeneity on colloid immobilization. This was especially true for smaller colloids because they were more sensitive to microscopic heterogeneities that produced mainly irreversible interaction in a primary minimum and greater hysteresis in S sub(f)(IS) with IS. Significant deviations between experimental and predicted values of alpha (IS) were observed for larger colloids when hydrodynamic forces were not accounted for in the predictions. A sensitivity analysis indicated that colloid release with IS transients was not diffusion controlled, but rather occurred rapidly and with low levels of dispersion. The calibrated model provided a satisfactory description of the observed release behavior for a range of colloid types and sizes and a general theoretical foundation to develop predictions for the influence of solution chemistry on the transport, retention, and release of colloids.

Modified Morgan P (MMP) is a soil test P used to estimate plant available P in soils. The critical values of MMP for P fertilization and maintenance recommendations are based on the P concentrations measured by a common colorimetric molybdenum blue method although other P quantification methods have also been used for MMP measurements. In this study, we collected 120 surface soil samples of Caribou Sandy loam under potato cultivation or its rotation crops from Maine, USA, and 72 soil samples of Cecil sandy loam with cotton/corn crops under conventional tillage and no-till management with chemical and poultry litter fertilization in Georgia, USA. The MMP levels in all 192 dry samples were greater when they were measured by an inductively coupled plasma (ICP)-based method, compared to the corresponding data produced from colorimetry. Our results show the two sets of data were positively and significantly correlated (r = 0.93, P < 0.001). In average, the ICP-based MMP level of the 192 samples was 23.3 mg P kg-1 with standard deviation of 12.9, compared to the average of colorimetric MMP level of 14.9 mg P kg-1 with standard deviation of 8.8. Based on the observations in this work, both colorimetric and ICP-based methods can be used for P fertilizer recommendation, but a conversion factor should be applied for ICP data as the current recommendation systems are based on colorimetric M&R data.

Soils with high micro-bial activity may experience N immobilization (or reduced net N mineralization), and this issue remains unresolved in how to predict these conditions of net mineralization or net immobilization. Prediction may become possible with the use of a more sensitive method to determine soil C:N ratios stemming from the water-extractable C and N pools that can be readily adapted by both commercial and university soil testing labs. Soil microbial activity is highly related to soil organic C and N, as well as to water-extractable organic C (WEOC) and water-extractable organic N (WEON). The relationship between soil respiration and WEOC and WEON is stronger than between respiration and soil organic C (SOC) and total organic N (TON). We explored the relationship between soil organic C:N and water-extractable organic C:N, as well as their relationship to soil microbial activity as measured by the flush of CO2 following rewetting of dried soil. In 50 different soils, the relationship between soil microbial activity and water-extractable organic C:N was much stronger than for soil organic C: N. We concluded that the water-extractable organic C:N was a more sensitive measurement of the soil substrate which drives soil microbial activity. We also suggest that a water-extractable organic C:N level > 20 be used as a practical threshold to separate those soils that may have immobilized N with high microbial activity.

Ethanol, a product of grain fermentation, is known to inactivate several hydrolytic enzymes but its effect on phytases is relatively unknown. In this study, two phytases, Aspergillus niger (PhyA) and Escherichia coli (AppA2), were tested for ETOH tolerance. The E. coli phytase displayed greater ethanol tolerance over fungal phytase in the 5% to 10% range. However, ETOH inactivation was found to be reversible for both the enzymes. These differences in ETOH tolerance do suggest that there is a potential to achieve higher ETOH tolerance in phytases by 'structure-function' studies to lower phytic acid levels in DDGS and for other applications.

Our objective was to quantify neonate survival rates and causes of mortality at the United States Department of Energy's Savannah River Site (SRS), South Carolina to directly evaluate degree of predation in this deer population. From 2006 to 2009, we radio-monitored 91 neonates captured with the aid of vaginal implant transmitters in pregnant adult females and opportunistic searches. Overall Kaplan-Meier survival rate to 16 weeks of age was 0.230 (95% CI=0.155-0.328), and it varied little among years. Our best-fitting model estimated survival at 0.220 (95% CI=0.144-0.320). This model included a quadratic time trend variable (lowest survival rate during the first week of life and increasing to near 1.000 around week 10), and Julian date of birth (survival probability declining as date of birth increased). Predation by coyotes was the most frequent cause of death among the 70 monitored neonates that died, definitively accounting for 37% of all mortalities and potentially accounting for as much as 80% when also including probable coyote predation. Predation by bobcats (Felis rufus) accounted for 7% (definitive) to 9% (including probable bobcat predation) of mortalities. The level of coyote-induced mortality we observed is consistent with the low recruitment rates exhibited in the SRS deer population since establishment of coyotes at the site. If representative of recruitment rates across South Carolina, current harvest levels appear unsustainable. This understanding is consistent with the recent declining trend in the statewide deer population. The effects of coyote predation on recruitment should be considered when setting harvest goals, regardless of whether local deer population size is currently above or below desired levels, because coyotes can substantially reduce fawn recruitment.

Many headwater streams and their riparian habitats in this region have been modified for agricultural drainage. Riparian habitat modifications caused by agricultural drainage may influence aquatic macroinvertebrate colonization within the riparian zones of headwater streams. However, the effects of agricultural drainage-induced riparian modifications have not been evaluated because others have focused on the impact of agricultural drainage on aquatic macroinvertebrates within the streams. We placed water-filled mesocosms in the riparian zones of two channelized and two unchannelized streams in central Ohio and sampled them from June to August 2009 to determine if differences in physical habitat, water chemistry, and aquatic macroinvertebrate colonization occurred between riparian zone types and among sampling dates. Canopy cover was greater in unchannelized than channelized riparian zones. Dissolved oxygen was greater in channelized than unchannelized riparian zones only during the latter half of the study. Turbidity and nutrients progressively increased throughout the study. Taxa richness was greater in unchannelized than channelized riparian zones. Copepod relative abundance, zooplankton relative abundance, and Shannon diversity index was greater in unchannelized than channelized riparian zones only during the latter half of the study.

Probability of mortality increased with virus concentration as observed after 7 and 10 days of feeding on virus treated diet in neonates and second instar larvae. LC sub(50) estimates for neonates at 7 and 10 days was 2743 and 389 occlusion bodies (OBs)/mm super(2). For second instars, LC sub(50) was 139,487 and 813 OBs/mm super(2) at 7 and 10 days. There was no biologically significant mortality response to increasing virus concentrations by fourth instar larvae; however, when fourth instar larvae were infected with virus on diet and then fed apple leaves, the leaf area consumed declined up to 50% with higher virus concentrations. In a greenhouse study, neonate larvae that fed on seedlings treated with water showed >90% survival and 80% pupation rate of larvae after being transferred to diet. In contrast, larvae that fed on apple seedlings sprayed with 3 x 10 super(6) OBs/ml showed poor survival when transferred to diet after acquiring the virus and failed to reach the pupal stage. This virus shows promise for population regulation and can produce reduction in feeding damage.

Owing to their natural food origin and biocompatibility, we exploited further their potential as a drug delivery system and pharmaceutical excipients. This work aimed to investigate self-assembly, thermal transition, interaction with various drugs and surface activity of these novel amphiphilic polymers. The critical micelle concentration of HPSO and HPESO was determined by the surface tension method. The molecular interaction between HPESO and anticancer drug doxorubicin HCl was examined. The effect of the polymers on the solution contact angle and surface energy of compressed tablets of hydrophobic drugs ibuprofen and nifedipine was measured. The thermal transition temperatures T(tr) (cloud points) of the polymers in aqueous solutions increased with increasing polymer concentration. HPSO exhibited lower T(tr) than HPESO. The critical micelle concentration was found to be 0.05 mg mL(-1) for HPSO and 0.08 mg mL(-1) for HPESO. Strong molecular interactions between HPESO and doxorubicin were observed. Both polymers reduced the interfacial energy and contact angles of drug tablets with more effect on ibuprofen tablets with the use of HPSO. These results suggest that the novel soybean-oil-based amphiphilic polymers have great potential for drug delivery and pharmaceutical formulations.

Solutions and films were prepared from the granules. Gel electrophoresis and refractive index were used to examine changes in molecular weight of the samples. Also, the gel strength and rheological properties of the solutions as well as the tensile and water vapor barrier properties of the films were characterized. SDS-PAGE and refractive index results indicated cross-linking of gelatin chains after exposure to radiation. Interestingly, UV-B treated samples displayed higher gel strengths, with cold- and warm-water fish gelatin having gel strength increases from 1.39 to 2.11 N and from 7.15 to 8.34 N, respectively. In addition, both gelatin samples exhibited an increase in viscosity for higher UV doses. For gelatin films, the cold-water fish gelatin samples made from irradiated granules showed greater tensile strength. In comparison, the warm-water gelatin films made from irradiated granules had lower tensile strength, but better water vapor barrier properties. This might be due to the UV induced cross-linking in warm-water gelatin that disrupted helical structures.

It can cause rare but invasive infections in neonatal infants who consume contaminated PIF. The objective of this research was to investigate the growth kinetics and develop mathematical models to predict the growth of heat-injured C. sakazakii in reconstituted PIF (RPIF). RPIF, inoculated with a 6-strain cocktail of non-heat-treated (uninjured) or heat-injured C. sakazakii, was incubated at different temperatures to develop growth models. Except for storage at 6 degree C, C. sakazakii grew well at all test temperatures (10 to 48 degree C). Uninjured C. sakazakii exhibited no observable lag phase, while a lag phase was apparent in heat-treated cells. A simple 3-parameter logistic equation was used to fit growth curves for non-heat-treated cells, while both Baranyi and Huang models were suitable for heat-treated C. sakazakii. Calculated minimum and maximum growth temperatures were 6.5 and 51.4 degree C for non-heat-treated cells, and 6.9 and 50.1 degree C for heat-treated cells of C. sakazakii in RPIF, respectively. There was no significant difference between growth rates of non-heat-treated and heat-injured cells in RPIF. For heat-treated cells of C. sakazakii, the lag phase was temperature-dependent and very short (between 25 degree C and 48 degree C). These results suggest that both non-heat-treated and heat-injured C. sakazakii cells may present a risk to infants if the pathogens are not completely destroyed by heat in RPIF and then exposed to subsequent temperature abuse. Practical Application:C. sakazakii is a life-threatening bacterium found in powdered infant formula (PIF). This study shows that the uninjured bacterium exhibits very short or no lag phase if not refrigerated and can grow well in reconstituted PIF (RPIF), while the heat-injured cells can multiply at an equivalent rate following metabolic recovery. Temperature abuse may allow C. sakazakii to grow and endanger infants fed with RPIF. Predictive models developed in this study can be used to estimate the growth and conduct risk assessments of this pathogen.

Compost filter socks placed in grassed waterways can further reduce sediment concentration as runoff is transmitted offsite but are generally ineffective in removing dissolved chemicals. Therefore, we investigated the effect of adding a proprietary sorbent, Nutriloxx, to filter socks filled with composted bark and wood chips on sediment, nutrient, and glyphosate concentrations in runoff. Surface runoff from one tilled and one no-till watershed planted to corn (Zca mays L.) was routed into two parallel, 30 m (99 ft) long, grassed waterways. Three, 46 cm (18 in) diameter filter socks filled with Nutriloxx-amended compost were placed 5 m (16.5 ft) apart across the upper half of one waterway and in the lower half of the paired waterway. Automated samplers were used to obtain samples above and below the treated waterway segments in the 2009 and 2010 crop years. The effectiveness of the grassed waterways and filter socks was highly dependent on tillage treatment and timing and size of the runoff events. In 2009, there were no sizable events during the early growing season. Consequently, erosion was minimal, and no significant effects on sediment concentration were detected. Averaged for both watersheds, however, the amended filter socks contributed to an additional 28% reduction in dissolved phosphate-phosphorus (PO sub(4)-P) concentration compared to waterway segments without filter socks (significant at p = 0.05). The filter socks, however, significantly increased sulfate (SO sub(4)) concentrations up to 20-fold in the first sampled event, but SO sub(4) concentrations declined rapidly with subsequent events. Similarly, the filter socks increased concentrations of calcium (Ca), potassium (K), and sodium (Na), but this was not significant in all instances. In 2010, runoff-producing rainfall occurred frequently during the growing season, and the filter socks significantly decreased sediment and PO sub(4)-P concentrations from the tilled watershed. In addition, large reductions in ammonium-nitrogen (NH sub(4)-N) concentrations were noted (average > 7-fold), but field observations suggested that this was due to physical trapping of eroded coated-urea fertilizer prills rather than sorption. The filter socks continued to contribute to significantly increased SO sub(4) concentrations from both watersheds. Filter socks can effectively reduce sediment losses when used in agricultural applications, and adding selective sorbents can increase their ability to retain nutrients. However, losses of sorbent components need to be considered.

This study evaluated the potential impacts of precipitation changes on soil erosion and surface runoff in southeastern Arizona using seven General Circulation Model (GCM) models with three emission scenarios for the 2050s and 2090s. A spatial-temporal downscaling process was used to generate daily precipitation series from GCM outputs for runoff and erosion modeling with the Rangeland Hydrology and Erosion Model (RHEM). Results were compared to 1970 through 1999 conditions. Our results suggested no significant changes in annual precipitation across the region under the three emission scenarios, while projected mean annual runoff and soil loss increased significantly, ranging from 79% to 92% and from 127% to 157%, respectively, relative to 1970 to 1999. At the seasonal scale, though an increase of summer precipitation and a reduction of winter precipitation were projected, both runoff and soil loss increased significantly for both periods. The dramatic increases in runoff and soil loss were attributed to the increase in the frequency and intensity of extreme events in the study area. Predicted soil loss from shrub communities increased more than that predicted for other plant communities under the three emission scenarios. Future increases in runoff and soil erosion may accelerate the transitions of grassland to shrub-lands or to more eroded states due to the positive vegetation-erosion feedback. Rangeland management policies and practices should consider these changes and adapt to the increased risk of runoff and soil erosion.

In this study, the soil conditioning index (SCI) embedded in the Revised Universal Soil Loss Equation (RUSLE2) model was used to predict (1) potential soil organic C sequestration under conventional and conservation management of a diversity of cotton cropping systems throughout the Cotton Belt and (2) relative influences of soil texture, slope, climatic conditions, and management on potential soil organic C sequestration. Across 10 regions of the Cotton Belt, SCI scores ranked in the following order: perennial pasture > no-till cropping systems > conventional tillage cotton. Variations in significance of SCI scores occurred among 5 different no-till cropping systems within regions of the Cotton Belt. For example, 7 of the 10 regions had significantly (p less than or equal to 0.05) greater SCI scores (linked to greater soil organic C sequestration) when monoculture cotton was grown with winter cover crop than without. Variation in SCI was dominated by management (46%) and slope (24%) and very little affected by climate (7%) and soil texture (1%). Increasingly wetter climatic conditions (as expressed by increasing precipitation to potential evapotranspiration) had a negative influence on SCI scores for all management systems and land slopes evaluated, but particularly for moldboard-plowed cotton on sloping land. With a linear relationship between SCI and soil organic C sequestration, predicted soil organic C sequestration averaged -0.31 plus or minus 0.19 Mg C ha super(-1) y super(-1) (-280 plus or minus 170 1b ac super(-1) yr super(-1)) under conventionally tilled cotton, 0.12 plus or minus 0.06 Mg C ha super(-1) y super(-1) (103 plus or minus 52 1b ac super(-1) yr super(-1)) under various no-till crop rotations, and 0.26 plus or minus 0.02 Mg C ha super(-1) y super(-1) (231 plus or minus 20 1b ac super(-1) yr super(-1)) under perennial pasture. Cotton production with conventional tillage could only be expected to maintain soil organic C under a best-case scenario and would lose substantial soil organic C under most other scenarios. Simulations showed the strong, positive influence that conservation agricultural management has to sequester soil organic C, irrespective of climate, slope, and texture.

Extensive databases describing climate, soils, and management options have been developed and are widely used in the United States for conservation planning. Recent RUSLE2 enhancements allow estimation of erosion and runoff from a representative sequence of runoff events that are suitable for linkage with an ephemeral gully model. This paper reviews the sensitivity of RUSLE2 erosion estimates to possible climate change scenarios, demonstrates its ability to evaluate alternative management adaptations, and compares predictions with observations of runoff and sediment yield from a 6.6 ha (16 ac) research watershed located nearTreynor, Iowa. When applied to a representative hillslope profile with conventional tillage corn (Zea mays L.), increasing monthly temperature by 0.8 degree C (1.5 degree F) and rainfall depth, rainfall erosivity density, and 10-year, 24-hour rainfall depth each by 10% cumulatively increased sheet and rill erosion by 47% and increased runoff by 33%, assuming there was no change in corn yield. If the climate changes decreased corn yield by 10%, the overall effect was to increase soil loss for conservation planning by 63%. These results demonstrate that modest and expected changes in climate will significantly increase the risk of soil erosion, and improved conservation management will be an important part of successful adaptation.

Climate change scenarios predict a 2.2 degree C to 3.6 degree C (4 degree F to 6.5 degree F) increase and more variability in precipitation across most of the United States. This study quantifies management effects (native grassland, Conservation Reserve Program [CRP], and cropped) on SOC and SON stocks across the region and assessed soil variables (soil texture, cation exchange capacity, and others) and climatic drivers (precipitation and temperature) to predict future changes in carbon (C) and nitrogen (N) stocks. Across all sites, cropped land had significantly lower C and N stocks in the 0 to 5 cm (0 to 2 in) and 0 to 10 cm (0 to 3.9 in) depths than native sites, while CRP sites were intermediate. Mean annual temperature (MAT), the ratio of mean annual precipitation to potential evapotranspiration (MAP:PET), soil bulk density (BD), and clay content were important covariates for SOC and SON stocks within land use. Soil C and N stocks under all three land uses were strongly negatively related to MAT and positively related to MAP:PET, suggesting that they are equally vulnerable to increased temperature and decreasing water availability. Based on these empirical relationships, a 1 degree C (1.8 degree F) increase in MAT could cause a loss of 486 Tg SOC (536 million tn) and a loss of 180 kg SON ha super(-1) (160 lb SON ac super(-1)) from the top 10 cm (3.9 in) of soil over 30 years, but the decrease will be mediated by water availability (MAP:PET). Combined, increased temperature and conversion from CRP to cropland could decrease the existing SOC sink, but improved soil management and increased water availability may help offset these losses in the US Great Plains.

Here the hypothesis that vaccination with the same rFHAB2 peptides could cross-protect turkeys against challenge with P. multocida chi 73 (serotype A:1) was examined. Three rFHAB2 peptides were purified and pooled, and two doses, consisting of equal amounts of each, were administered subcutaneously to turkeys at 2-wk intervals. Simultaneously, control birds were administered sham inoculations. One week later, vaccinates and controls were challenged intranasally with P-1059 or chi 73. The results showed vaccination with rFHAB2 peptides significantly protected turkeys against lethal challenge from both P. multocida serotypes (P < 0.01). The high degree of FHAB2 conservation across serotypes likely allow the observed cross-protection.

During a study of crow roost dispersal in Lancaster, PA, we collected samples of pellets from several locations. By mass, pellets consisted mostly of grit and other fine inorganic material, various seeds (principally Toxicodendron radicans [PoisonIvy] and Celtis occidentalis [CommonHackberry]), and vegetation remnants. Six pellets contained small-mammal bones. Because the Lancaster winter crow population included many Fish Crows, the source of the pellets was not certain. To clarify this, we compared the size of the Lancaster crow pellets to those produced by captive Fish Crows, and we provide the first quantitative description of pellets for either species. Our size comparisons suggest that >90% of the pellets in our sample from Lancaster were produced by American Crows.

Schultes] Barkworth) is a widely distributed, highly desirable native species in desert ecosystems in the western United States. Yet there are no studies linking genetic variation in Indian ricegrass with climate across major areas of its natural distribution. In this study, seeds from 106 collection locations from the southwestern United States were established in common gardens and four phenological traits (Phen; such as blooming date), six production traits (Pro; such as dry weight), and eight morphology traits (Morph; such as leaf dimensions) were measured in 2007 and 2008. Analyses of variance revealed that all basic garden traits differed among source locations (P plus or minus 0.25, P plus or minus 0.25, P<0.01) unieron consistentemente cada mes con la temperatura en cada coleccion y locacion con Phen 1, Pro 1, and Morph 1. Para precipitacion, sin embargo, las correlaciones fueron mas dependientes de la variable mes, con las relaciones mas fuerte en el periodo de desarrollo de primavera. Usando los modelos de regresion entre las caracteristicas climaticas un mapa con 12 zonas de coleccion de semillas fue desarrollado representando la mayor parte del suroeste de Estados Unidos. Este mapa en general distinguio la variacion genetica entre las regiones mas frias y las mas calidas, separando las localizadas mas hacia el norte, con elevaciones mas altas de las areas mas hacia el sur con elevaciones mas bajas.

Since the 1950s shrub removal has been primarily achieved with herbicides. Concerns over declining lesser prairie-chicken (Tympanuchus pallidicinctus; LPC) populations have led to increased scrutiny over the use of herbicides to control shrubs. The objective of our research was to describe changes to LPC habitat qualities following chemical control of sand sagebrush in northwest Oklahoma. Study pastures ranged in size from 10 to 21 ha. Five pastures were sprayed with 2,4-dichlorophenoxyacetic acid (2,4-D) in 2003 (RECENT), five were sprayed with 2,4-D in 1984 (OLD), and four received no treatment (SAGE). We measured habitat structure (sagebrush cover, sagebrush density, visual obstruction [VO], and basal grass cover), and dietary resources (forb density, forb richness, and grasshopper density) in all pastures from 2003 to 2006. OLD and RECENT pastures had less sagebrush (cover and density) and VO than SAGE pastures. OLD pastures produced more annual forbs than either SAGE or RECENT pastures. SAGE pastures had more perennial forbs than RECENT pastures. Herbicide application reduced protective cover while providing no increase in forb abundance in RECENT pastures. Our results indicated that it may take several years to realize increases in annual forbs following application of 2,4-D. However, loss of protective cover may persist for multiple years (20+ yr), and removal of sagebrush did not increase forb richness or grasshopper abundance. Thus, 2,4-D may have limited use as a habitat management tool because it takes numerous years to reap the benefit of increased forb abundance while reducing habitat structure in the long term. El manejo tradicional de pastizales de artemisa (Artemisia filifolia) ha enfatizado el control de artemisa para aumentar el forraje para el ganado. Desde los 1950s la remocion de arbustivas ha sido lograda principalmente con herbicidas. La preocupacion por la disminucion de las poblaciones de gallinas de pradera (Tympanuchus pallidicinctus; LPC) ha llevado a aumentar la vigilancia sobre el uso de herbicidas para el control de arbustivas. El objetivo de nuestra investigacion fue describir los cambios en la calidad del habitat de LPC despues de controles quimicos de Artemisia filifolia en el noroeste de Oklahoma. Los potreros en estudio variaron en tamano de 10 a 21 ha. Cinco potreros fueron asperjados con 2,4-acido diclorofenoxiacetico (2,4-D) en 2003 (RECIENTE), otros cinco fueron asperjados con 2,4-D en 1984 (VIEJO) y cuatro no recibieron tratamiento (ARTEMISA). Medimos la estructura del habitat (cobertura y densidad de artemisa, obstruccion visual [OV] y cobertura basal de pastos) y fuentes de dieta (densidad y riqueza de hierbas y densidad de chapulines) en todos los potreros de 2003 a 2006. Potreros VIEJO Y RECIENTE tuvieron menos artemisa (cobertura y densidad) y OV que los potreros ARTEMISA. Los porteros VIEJO produjeron mas hierbas anuales los porteros ARTEMISA Y RECIENTE. Los potreros ARTEMISA tuvieron mas hierbas perennes que los potreros RECIENTE. La aplicacion de herbicida reduce la cubierta protectora mientras que no aumenta la abundancia de hierbas en los potreros RECIENTE. Nuestros resultados indican que puede tomar varios anos el lograr incrementar las hierbas anuales despues de la aplicacion de 2,4-D. Sin embargo, la perdida de cubierta protectora podra mantenerse por multiples anos (20+ anos) y el remover la artemisa no aumenta la riqueza de hierbas y abundancia de chapulines. Entonces, 2,4-D podra tener uso limitado como herramienta de manejo de habitat porque toma muchos anos obtener el beneficio de aumentar la abundancia de hierbas mientras que se reduce la estructura del habitat en el largo plazo.

This information is needed by local producers, biomass industry, and other stakeholders, and for larger scale analyses. This study models biomass production decisions at the field level using a case example of a biomass gasification facility constructed at the University of Minnesota-Morris (UMM). This institutional-scale application has an anticipated feedstock demand of about 8,000 Mg year super(-1). The model includes spatial impacts due to sub-field variation in soil characteristics and transportation costs. Results show that the amount of biomass producers could profitably supply within a 32.2-km radius of UMM increases as plant-gate biomass price increases from $59 to $84 Mg super(-1), with 588,000 Mg annual biomass supply at $84 Mg super(-1). Results also show that the most profitable tillage and crop rotation practices shift in response to increasing biomass price with producers shifting from a corn-soybean rotation toward continuous corn. While biomass harvest is conducive to increased soil erosion rates and reduced soil organic carbon levels, changes in crop production practices are shown to at least partially offset these impacts. Transportation costs tend to concentrate and intensify biomass production near the biomass facility, which also tends to concentrate environmental impacts near the facility.

Overall, approximately one million reads consisting of 216 million bases were assembled into 27,687 contigs and 43,094 singletons. Analyses of these sequences revealed minor contamination with non-plant sequences (< 0.5%), indicating that a majority were for transcripts coded by the switchgrass genome. Blast2Gos comparisons resulted in the annotation of ~65% of the contig sequences and ~40% of the singleton sequences. Contig sequences were mostly homologous to other plant sequences, dominated by matches to Sorghum bicolor genome. Singleton sequences, while displaying significant matches to S. bicolor, also contained sequences matching non-plant species. Comparisons of the 454 dataset to existing EST collections resulted in the identification of 30,177 new sequences. These new sequences coded for a number of different proteins and a selective analysis of two categories, namely, peroxidases and transcription factors, resulted in the identification of specific peroxidases and a number of low-abundance transcription factors expected to be involved in chromatin remodeling. KEGG maps for glycolysis and sugar metabolism showed high levels of transcript coding for enzymes involved in primary metabolism. The assembly provided significant insights into the status of these tissues and broadly indicated that there was active metabolism taking place in the crown and rhizomes at post-anthesis, the seed maturation stage of plant development.

Thus, it is no surprise that there is intense curiosity about its genetic and geographical origins, its response to selection under domestication, and the genetic structure of its wild relative, Oryza rufipogon. Studies of Oryza attempting to answer these questions have accompanied each stage of the development of molecular markers, starting with allozymes and continuing to genome sequencing. While many of these studies have been restricted to small sample sizes, in terms of either the number of markers used or the number and distribution of the accessions, costs are now low enough that researchers are including large numbers of molecular markers and accessions. How will these studies relate to previous findings and long-held assumptions about rice domestication and evolution? If the paper in this issue of Molecular Ecology (Huang 2012) is any indication, there will be some considerable surprises in store. In this study, a geographically and genomically thorough sampling of O. rufipogon and O. sativa revealed two genetically distinct groups of wild rice and also indicated that only one of these groups appears to be related to domesticated rice. While this fits well with previous studies indicating that there are genetic subdivisions within O. rufipogon, it stands in contrast to previous findings that the two major varieties of O. sativa (indica and japonica) were domesticated from two (or more) subpopulations of wild rice.

Obscure articles reveal alternative host plants for the coffee berry borer, Hypothenemus hampei (Coleoptera: Curculionidae) AN - 1093453993; 17083232 AB - The coffee berry borer, Hypothenemus hampei (Coleoptera: Curculionidae: Scolytinae), is the most devastating insect pest of coffee throughout the world. The insect is endemic to Africa but can now be found throughout nearly all coffee-producing countries. One area of basic biology of the insect that remains unresolved is that of its alternative host plants, i.e. which fruits of plants, other than coffee, can the insect survive and reproduce in. An in-depth survey of the literature revealed an article by Schedl listing 21 genera in 13 families in which the insect was collected, mainly in the Democratic Republic of Congo. This overlooked reference, together with information provided in other early articles, suggests that H.hampei is polyphagous, and could provide, if confirmed in the field, critical information on the evolution of this insect's diet, ecology and host range. copyright 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012].

Microscopic and behavioral studies on five hemipteran species from four families (Psyllidae, Aphididae, Cicadellidae, and Aleyrodidae) showed that their exuviae (molted skins) normally had either fully or partially extended stylets in a feeding-like position. In most cases these stylets were still partially embedded in their host plants after ecdysis, which indicated that plant-feeding hemipteran nymphs use their stylets to anchor themselves to host plants during molting. This phenomenon was used here to study the stylet length and ultrastructure in exuviae of various instars, which is normally more difficult in nymphs than in adults because of the fragility and smaller size of nymphs. Additionally, autofluorescence was used for studying the hemipteran salivary sheaths of nymphs and adults in their host plants. This method is based on fixation of free hand sections of plant parts on which hemipteran insects have been feeding, then mounting and examination of these sections with epifluorescence or confocal microscopy. No embedding, microtomy, or staining is necessary for this method that makes it much faster and simpler than other methods. Autofluorescence was also used to study the location and size of bacteriomes/mycetomes (organs containing symbionts) in hemipteran eggs and nymphs.

Yet, analyses of fragmentation and deforestation have focused primarily on the conversion of non-urban to urban landscapes in rural landscapes and ignored urban landscapes. To determine the ecological effects of continued urbanization in urban landscapes, tree-covered patches were mapped in the Gwynns Falls watershed (17158.6 ha) in Maryland for 1994 and 1999 to document fragmentation, deforestation, and reforestation. The watershed was divided into lower (urban core), middle (older suburbs), and upper (recent suburbs) subsections. Over the entire watershed a net of 264.5 of 4855.5 ha of tree-covered patches were converted to urban land use-125 new tree-covered patches were added through fragmentation, 4 were added through reforestation, 43 were lost through deforestation, and 7 were combined with an adjacent patch. In addition, 180 patches were reduced in size. In the urban core, deforestation continued with conversion to commercial land use. Because of the lack of vegetation, commercial land uses are problematic for both species conservation and derived ecosystem benefits. In the lower subsection, shape complexity increased for tree-covered patches less than 10 ha. Changes in shape resulted from canopy expansion, planted materials, and reforestation of vacant sites. In the middle and upper subsections, the shape index value for tree-covered patches decreased, indicating simplification. Density analyses of the subsections showed no change with respect to patch densities but pointed out the importance of small patches ( less than or equal to 5 ha) as "stepping stone" to link large patches (e.g., >100 ha). Using an urban forest effect model, we estimated, for the entire watershed, total carbon loss and pollution removal, from 1994 to 1999, to be 14,235,889.2 kg and 13,011.4 kg, respectively due to urban land-use conversions.

Beetle] plant communities historically shifted dominance from woody to herbaceous vegetation. However, fire return intervals have lengthened with European settlement, and sagebrush dominance has increased at the expense of herbaceous vegetation in some plant communities. Management actions may be needed to decrease sagebrush in dense sagebrush stands to increase herbaceous vegetation. Prescribed fire is often used to remove sagebrush; however, mechanical treatments, such as mowing, are increasingly used because they are more controllable and do not pose an inherent risk of escape compared with fire. However, information on the effects of burned and mowed treatments on herbaceous vegetation and whether fire and mowed applications elicit similar vegetation responses are limited. We evaluated the effects of prescribed burning and mowing for 3 years after treatment in mountain big sagebrush plant communities. The burned and mowed treatments generally increased herbaceous cover, density, and production compared with untreated controls (P 0.05). In contrast, annual forb (predominately natives) cover, density, and biomass increased with mowing and burning (P < 0.05). Vegetation generally responded similarly in burned and mowed treatments; however, the burned treatment had less sagebrush, greater herbaceous vegetation production, and more bare ground than the mowed treatment (P < 0.05). These differences should be considered when selecting treatments to decrease sagebrush.

Young) alliance is being severely interrupted by post-fire invasion of non-native annual grasses. To curtail this invasion, successful post-fire revegetation of perennial grasses is required. Environmental factors impacting post-fire restoration success vary across space within the Wyoming big sagebrush alliance; however, most restorative management practices are applied uniformly. Our objectives were to define probability of revegetation success over space using relevant soil-related environmental factors, use this information to model cost of successful revegetation and compare the importance of vegetation competition and soil factors to revegetation success. We studied a burned Wyoming big sagebrush landscape in southeast Oregon that was reseeded with perennial grasses. We collected soil and vegetation data at plots spaced at 30 m intervals along a 1.5 km transect in the first two years post-burn. Plots were classified as successful (>5 seedlings/m super(2)) or unsuccessful based on density of seeded species. Using logistic regression we found that abundance of competing vegetation correctly predicted revegetation success on 51 % of plots, and soil-related variables correctly predicted revegetation performance on 82.4 % of plots. Revegetation estimates varied from $167.06 to $43,033.94/ha across the 1.5 km transect based on probability of success, but were more homogenous at larger scales. Our experimental protocol provides managers with a technique to identify important environmental drivers of restoration success and this process will be of value for spatially allocating logistical and capital expenditures in a variable restoration environment.

The invasion often forms large, dense monocultural stands. We investigated the genetic diversity along transects in dense populations in the western USA using Amplified Fragment Length Polymorphisms. We also analyzed transect collections from the native Eurasian range for comparison. In addition, we conducted crossing studies to determine possible modes of seed production (sexual outcrossing vs. self-fertilization vs. apomixis). In our study of seed production we determined that self-fertilization and outcrossing both produce germinable seed in perennial pepperweed. Genetic diversity in the USA was unexpectedly low, with only three genotypes in 388 plants, and those three had genetic similarity of greater than or equal to 98%. Up to 97% of the plants from Turkey and Russia transects were unique genotypes, while <4% of USA plants in a transect were unique. This lack of diversity in the USA samples suggests that perennial pepperweed, despite its success as an invader, is not well-positioned to adapt to new selective pressures, or to recruit pre-adapted genotypes that may vary in resistance or tolerance to disease or herbivory. Because 99% of the USA plants were genetically identical, we were unable to determine if increases in stand size were due to spread by rhizomes or seed derived from outcrossing between genetically identical parents or self-fertilization, as each of these methods produces shoots genetically identical to parental plants.

Although they are dominant in mixed species forests and widely distributed, there are frequent reports of regeneration failures. An adequate population of large oak advance reproduction is a critical prerequisite to successful oak regeneration, and hence sustainability of oak. But, many oak forests lack sufficient density of large and competitive oak advance reproduction. Artificial regeneration of oak by underplanting is done to supplement natural populations of oak seedlings or to introduce oak in stands where it is missing. Planting high quality seedlings is important. Silvicultural practices that regulate stand density such as thinning and the shelterwood method are needed to increase oak's regeneration potential by promoting accumulation and growth of natural and planted seedlings before the final regeneration harvest. Control of competing vegetation and herbivory are important elements in the regeneration prescription. Light in the understory is a limiting factor to the accumulation of large oak advance reproduction. Light levels (20-50 % +) sufficient for biomass production in oak reproduction result through management of stand density and other competing vegetation. We review and synthesize the literature on silvicultural approaches to using artificial regeneration to obtain successful oak regeneration that is grounded in fundamental principles of oak biology and ecology. Principles of oak regeneration presented here may also have relevance to other hydric, mesic and dry-mesic forest environments.

We examined hardwood seedling survival and growth in an outdoor laboratory where the timing, depth, duration, and flow rate of flood water can be carefully controlled while simulating natural soil conditions occurring in floodplains. Flooding treatments were initiated in mid-May and included partial inundation (15-20 cm) during the growing season for 5-week flowing, 5-week standing, 3-week flowing, and control. We monitored the vigor, survival, and growth (changes in basal diameter and stem length) of six hardwood species representing a wide range in expected flood tolerance including eastern cottonwood (Populus deltoides Bartr. Ex Marsh.), pin oak (Quercus palustris Muenchh.), swamp white oak (Q. bicolor Willd.), bur oak (Q. macrocarpa Michx.), black walnut (Juglans nigra L.), and pecan [Carya illinoensis (Wangenh.) K. Koch]. All stock was 1-0 bareroot except that cuttings were used for eastern cottonwood. Five species-eastern cottonwood, bur oak, swamp white oak, pin oak, and pecan-exhibited high survival probabilities (>0.62 for cottonwood; >0.77 for the others) regardless of flood treatment. But of the survivors, only eastern cottonwood and swamp white oak maintained positive growth and healthy green foliage. Despite high survival, bur oak and pin oak suffered stem growth losses and exhibited chlorotic foliage in flood treatments suggesting greater vulnerability to other abiotic or biotic stresses if outplanted on flood-prone sites. Pecan also suffered stem dieback in controls suggesting vulnerability to competition and browsing when outplanted despite high survival after flooding. Our quantitative data helps to confirm and/or refine previously published qualitative flood tolerance ratings for these species, and describes operation of an in situ outdoor flood experiment laboratory that may prove effective in guiding future flood tolerance research.

These debilities are associated with accumulation of toxic protein aggregates as observed in other protein precipitation or amyloid diseases including Alzheimer, Parkinson and Huntington diseases and encephalopathies. Barriers to recommending lower-GI diets to promote health include the absence of established intracellular biochemical mechanisms that link high-GI diets to compromised homeostasis. The data herein corroborate the epidemiological findings and provide platforms to elucidate additional mechanistic aspects of salutary effects of consuming diets of different GIs. They are also useful for testing drugs, including autophagy enhancers, glycemia regulators, or nutraceuticals, which can be exploited to extend health.

African Americans tend to have poor vitamin D status and increased risk of diabetes, but effects of vitamin D supplementation on components of diabetes risk have not been tested in this group. This study was conducted to determine whether vitamin D supplementation improves insulin secretion, insulin sensitivity and glycaemia in African Americans with prediabetes or early diabetes. Methods: In this randomized, placebo-controlled trial, we examined the effect of 4000 IU/day vitamin D3, on glycaemia and contributing measures including insulin secretion, insulin sensitivity and the disposition index over 12 weeks in 89 overweight or obese African Americans with prediabetes or early diabetes. Outcome measures were derived from oral glucose tolerance testing. Results: Mean plasma 25-hydroxyvitamin D was about 40 nmol/l in the placebo and vitamin D groups at baseline and increased to 81 nmol/l with supplementation. Insulin sensitivity decreased by 4% in the vitamin D group compared with a 12% increase in the placebo group (p = 0.034). Insulin secretion increased by 12% in the vitamin D group compared with a 2% increase in the placebo group (p = 0.024), but changes in the disposition index were similar across groups. There was no effect of supplementation on post-load glucose or other measures of glycaemia. Conclusions: Supplementation with 4000 IU/day vitamin D3 successfully corrected vitamin D insufficiency and had divergent effects on insulin secretion and sensitivity with no overall effect on disposition index or glycaemia. In this study, vitamin D supplementation for 3 months did not change the pathophysiology of prediabetes in overweight and obese African Americans.

Experiment 1 evaluated copper sulphate, florfenicol-medicated feed and potassium permanganate (KMnO4) against a natural mixed infection. Experiment 2 further evaluated copper sulphate as a treatment to control an experimental mixed infection. In experiment 1, naturally infected untreated fish had the lowest final survival per cent, at 71%, while florfenicol-medicated feed at 15mgkg-1 body weight for 10days or copper sulphate at 2.1mgL-1 (1% of the total alkalinity) for 24h produced the highest final survivals, at 90% and 88%, respectively. The final survival of the naturally infected fish administered florfenicol-medicated feed was significantly different (P<0.1) from the untreated fish. The survival curves for the florfenicol and the copper sulphate at 2.1mgL-1 were significantly improved from the untreated fish. In experiment 2, fish were challenged by waterborne exposure to A. hydrophila and F. columnare and either not treated or treated with copper sulphate at 2.1mgL-1. At the end of experiment 2, the per cent survival of the challenged fish treated with copper sulphate (99%) was significantly higher (P<0.05) than the non-treated (61%). The results illustrate clear benefit of florfenicol and copper sulphate against a mixed infection of A. hydrophila and F. columnare.

Five multiple drug-resistant (MDR) E. coli strains that possessed 0, 2, 6 or 8 plasmids were inoculated into anoxic faecal cultures from swine fed an unsupplemented (control) or chlortetracycline (50 g ton-1)-supplemented (experimental) diet. On days 21 of chlortetracycline supplementation, faecal growth competition studies were performed. MDR E. coli were enumerated at 0, 6 and 24 h. The plasmid-free strain was below culturable limits in both the control and experimental cultures by 24 h. For each plasmid-bearing strain, there was no statistically significant difference in population CFU ml-1 (P < 0.05) between the control and experimental cultures. There was no significant effect on the faecal microflora, owing to the inclusion of chlortetracycline, in the swine diets, that affected the growth of E. coli in the competition studies employed. Furthermore, these results suggest that the cost of maintaining plasmids in these E. coli strains had little influence on survivability. Mutations that led to antimicrobial resistance may have a greater impact on survivability than multiple plasmid carriage.

A large proportion of the landscape falls into one of several categories of protected lands. However, protected lands in the region are primarily higher elevation forest and mountain habitats. Little is known about how the network of protected lands may maintain connectivity for a broad spectrum of species expressing different habitat requirements and dispersal abilities. Location The study was conducted across the states of Montana and northern Idaho, USA, comprising an area of 30.2 million hectares. Methods We used resistant kernel modelling to map the extent of the study area predicted to be connected by dispersal for each of 35 species groups with different ecological associations. We evaluated the effect of vagility on protected area sufficiency by varying dispersal ability across three levels for each species group. We evaluated the degree of vulnerability of each of the 105 hypothetical species (35 species groups3 dispersal abilities) in terms of the extent of the total study area predicted to be connected by dispersal. We defined nine categories of risk as the combination of species vulnerability because of the extent of connected habitat and the degree to which that habitat was protected. Results We found high variation in the vulnerability of species because of the extent of connected habitat, and the extent to which connected habitat overlapped protected lands. Species associated with high elevations and species associated with lower elevations were predicted to have limited extent of connected habitat. Species associated with high elevations were predicted to have the vast majority of their connected habitat protected by federal Forest Service and National Park Service lands. In contrast, species associated with lower elevations were poorly protected by the existing network of protected lands. Main conclusions Low elevation and non-forest habitats are at highest risk of human-induced habitat loss and fragmentation in the study area. Conservation efforts in the region may be most effective if they focus on expanding the network of lower elevation protected lands in such a way that maximizes connectivity across the landscape.

Therefore, a greenhouse study was conducted to determine the survival of E. coli O157:H7 in highly controlled soil matrices subjected to two variable environmental stressors: (1) soil volumetric water content (25 or 45 % VWC), and (2) the growth of clover (planted or unplanted). During the 7-week study, molecular-based qPCR analyses revealed that E. coli O157:H7 survival was significantly lower in soils maintained at either near water-holding capacity (45 % VWC) or under clover growth. The significant reduction under clover growth was only observed when E. coli populations were determined relative to all bacteria, indicating the need to further study the competition between E. coli O157:H7 and the total bacterial community in organic soils. Given the significant effect of clover on E. coli O157:H7 survival under different moisture conditions in this greenhouse-based study, this work highlights the antimicrobial potential of clover exudates in arable soils, and future work should concentrate on their specific mechanisms of inhibition; ultimately leading to the development of crop rotations/production systems to improve pre-harvest food safety and security in minimally processed, ready-to-eat and organic production systems.

AN - 1038068911; 22815244 AB - Fumonisins (FB) are mycotoxins found in maize. The purpose of this study was to (i) determine the relationship between FB(1) , FB(2) , and FB(3) intake and urinary excretion in humans, (ii) validate a method to isolate urinary FB on C(18) -SPE cartridges for international shipment, and (iii) test the method using samples from Guatemala. Volunteers (n = 10) consumed 206 grams/day of tortillas and biscuits prepared from masa flour and a product containing maize flour. Volunteers estimated their daily urine output and samples were analyzed for FB(1) , FB(2) , and FB(3) and hydrolyzed FB(1) . Only FB(1) was detected in urine suggesting lower absorption of FB(2) and FB(3) . Excretion was highly variable peaking soon after consumption began and decreasing rapidly after consumption stopped. Within 5 days after consumption ended, FB(1) was not detected in urine. In a study with eight volunteers, the average total urinary FB(1) was 0.5% of the intake. FB(1) was detected in 61% (107/177) of the samples collected in Guatemala. The results support the use of urinary FB(1) to assess ongoing exposure in population-based studies. However, relating the FB(1) concentration in urine to dietary intake of FB by individual subjects will be complicated due to interindividual variability and the rapidity of clearance. © 2012 WILEY-VCH Verlag GmbH & Co.

Vegetated drainage ditches lining agricultural fields have been investigated for their potential to mitigate runoff, acting similarly to a wetland as they filter contaminants. It is hypothesized that some aquatic macrophytes will be more effective at removing phosphate than others. In a mesocosm study, three aquatic macrophyte species, cutgrass (Leersia oryzoides), cattail (Typha latifolia), and bur-reed (Sparganium americanum), were investigated for their ability to mitigate phosphate from water. Mesocosms were exposed to flowing phosphate-enriched water (10 mg L super(-1)) for 6 h, left stagnant for 42 h, and then flushed with non-nutrient enriched water for an additional 6 h to simulate flushing effects of a second storm event. Both L. oryzoides and T. latifolia decreased the load of dissolved phosphate (DP) in outflows by greater than 50 %, significantly more than S. americanum, which only decreased DP by 15 plus or minus 6 % (p less than or equal to 0.002). All treatments decreased concentrations inside mesocosms by 90 % or more after 1 week, though the decrease occurred more rapidly in T. latifolia and L. oryzoides mesocosms. By discovering which species are better at mitigating phosphate in agricultural runoff, planning the community composition of vegetation in drainage ditches and constructed wetlands can be improved for optimal remediation results.

Using this model, in which p-cresol concentrations were calculated based on lagoon evaporation and net available radiation at the lagoon surface, predicted p-cresol concentrations were highest during the months of March and April and declined to very low levels thereafter. This was in accordance with observed emission patterns in the previous study. In the same period during which predicted emissions increased, wastewater concentrations of malodorants decreased. While other indicators of wastewater quality such as ammonium and chemical oxygen demand (COD) also decreased in concentration, the magnitude of their improvement was not as high as for the malodorants. There were no pronounced differences in bacterial populations between the cool and warm seasons based on molecular quantification of genes targeting total cells, Bacteroides, Clostridia, and methanogens. While the improvement in the concentrations of wastewater malodorants may be due to catabolism by lagoon bacteria, our findings indicate that evaporative losses that occurred as the lagoon warmed may also play a strong role.

AN - 1030350623; 22640634 AB - The yellow mealworm, Tenebrio molitor, is a pest of stored grain products and is sensitive to the Bacillus thuringiensis (Bt) Cry3Aa toxin. As digestive peptidases are a determining factor in Cry toxicity and resistance, we evaluated the expression of peptidase transcripts in the midgut of T. molitor larvae fed either a control or Cry3Aa protoxin diet for 24 h (RNA-Seq), or in larvae exposed to the protoxin for 6, 12, or 24 h (microarrays). Cysteine peptidase transcripts (9) were similar to cathepsins B, L, and K, and their expression did not vary more than 2.5-fold in control and Cry3Aa-treated larvae. Serine peptidase transcripts (48) included trypsin, chymotrypsin and chymotrypsin-like, elastase 1-like, and unclassified serine peptidases, as well as homologs lacking functional amino acids. Highly expressed trypsin and chymotrypsin transcripts were severely repressed, and most serine peptidase transcripts were expressed 2- to 15-fold lower in Cry3Aa-treated larvae. Many serine peptidase and homolog transcripts were found only in control larvae. However, expression of a few serine peptidase transcripts was increased or found only in Cry3Aa-treated larvae. Therefore, Bt intoxication significantly impacted the expression of serine peptidases, potentially important in protoxin processing, while the insect maintained the production of critical digestive cysteine peptidases.

How can managers map tropical forest tree communities with satellite imagery given these challenges? Here we describe a case study of mapping tropical forests to floristic classes with gap-filled Landsat imagery by judicious combination of field and remote sensing work. For managers, we include background on current and forthcoming solutions to the problems of mapping detailed tropical forest types with Landsat imagery. In the study area, Trinidad and Tobago, class characteristics like deciduousness allowed discrimination of floristic classes. We also discovered that we could identify most of the tree communities in (1) imagery with fine spatial resolution of [el]1m; (2) multiseason fine resolution imagery (viewable with Google Earth); or (3) Landsat imagery from different dates, particularly imagery from drought years, even if decades old, allowing us to collect the extensive training data needed for mapping tropical forest types with "noisy" gap-filled imagery. Further, we show that gap-filled, synthetic multiseason Landsat imagery significantly improves class-specific accuracy for several seasonal forest associations. The class-specific improvements were better for comparing classification results; for in some cases increases in overall accuracy were small. These detailed mapping efforts can lead to new views of tropical forest landscapes. Here we learned that the xerophytic rain forest of Tobago is closely associated with ultramafic geology, helping to explain its unique physiognomy.

Using data collected from eddy covariance towers over grass and shrub ecosystems in Arizona, USA and Almeria, Spain, we used net ecosystem carbon dioxide exchange (NEE), gross ecosystem production (GEP), and other meteorological variables to examine the effects of the different precipitation seasonality. Considerable crossover behavior occurred between the two rainfall regimes. As expected in these usually water-limited ecosystems, precipitation magnitude and timing were the dominant drivers of carbon exchange, but temperature and/or light also played an important role in regulating GEP and NEE at all sites. If significant rainfall occurred in the winter at the Arizona sites, their behavior was characteristically Mediterranean whereby the carbon flux responses were delayed till springtime. Likewise, the Spanish Mediterranean sites showed immediate pulse-like responses to rainfall events in non-winter periods. The observed site differences were likely due to differences in vegetation, soils, and climatology. Together, these results support a more unified conceptual model for which processes governing carbon cycling in semiarid ecosystems need not differ between warm-season and cool-season rainfall regimes.

Here, a standardized method for measuring and mitigating sample inhibition in environmental water concentrates is described. Specifically, the method 1) employs a commercially available standard RNA control; 2) defines inhibition by the change in the quantification cycle (Cq) of the standard RNA control when added to the sample concentrate; and 3) calculates a dilution factor using a mathematical formula applied to the change in Cq to indicate the specific volume of nuclease-free water necessary to dilute the effect of inhibitors. The standardized inhibition method was applied to 3,193 large-volume water (surface, groundwater, drinking water, agricultural runoff, sewage) concentrates of which 1,074 (34%) were inhibited. Inhibition level was not related to sample volume. Samples collected from the same locations over a one to two year period had widely variable inhibition levels. The proportion of samples that could have been reported as false negatives if inhibition had not been mitigated was between 0.3% and 71%, depending on water source. These findings emphasize the importance of measuring and mitigating inhibition when reporting qPCR results for viral pathogens in environmental waters to minimize the likelihood of reporting false negatives and under-quantifying virus concentration.

AN - 1034803454; 22844873 AB - Locoism is a toxic syndrome of livestock caused by the ingestion of a subset of legumes known as locoweeds endemic to arid and semiarid regions of the western United States. Locoweeds contain the toxic alkaloid swainsonine, which is produced by the endophytic fungi Undifilum species. Two chemotypes of plants can coexist within toxic populations of locoweeds: chemotype 1 plants are defined as individuals containing swainsonine concentrations greater than 0.01% and quantitatively greater amounts of Undifilum, while chemotype 2 plants are defined as individuals containing less than 0.01% swainsonine and quantitatively smaller amounts of Undifilum. To elucidate the mechanisms that govern chemotypes, the amount of Undifilum in seeds/embryos was manipulated, thus altering subsequent swainsonine concentrations in three locoweed species: Astragalus mollissimus, Astragalus lentiginosus, and Oxytropis sericea. Chemotype 1 seeds that were fungicide-treated or had the seed coat removed resulted in plants with swainsonine concentrations comparable to those in chemotype 2 plants. Conversely, embryos from seeds of chemotypes 1 and 2 that were inoculated with the endophyte resulted in plants with swainsonine concentrations comparable to those of chemotype 1 plants. This reproducible interconversion between the two swainsonine chemotypes suggests that the quantity of endophyte present in the seed at the time of germination is a key determinant of the eventual chemotype. Additionally, this is the first report of the inoculation of locoweeds with the endophyte Undifilum species.

The relative and cumulative effects of these stressors on continental river flows are relatively unknown. In this study, we used an integrated water balance and flow routing model to evaluate the impacts of impervious cover and water withdrawal on river flow across the conterminous US at the 8-digit Hydrologic Unit Code (HUC) watershed scale. We then estimated the impacts of projected change in withdrawals, impervious cover, and climate under the B1 "Low" and A2 "High" emission scenarios on river flows by 2060. Our results suggest that compared to no impervious cover, 2010 levels of impervious cover increased river flows by 9.9% on average with larger impacts in and downstream of major metropolitan areas. In contrast, compared to no water withdrawals, 2005 withdrawals decreased river flows by 1.4% on average with larger impacts in heavily irrigated arid regions of Western US. By 2060, impacts of climate change were predicted to overwhelm the potential gain in river flow due to future changes in impervious cover and add to the potential reduction in river flows from withdrawals, decreasing mean annual river flows from 2010 levels by 16% on average. However, increases in impervious cover by 2060 may offset the impact of climate change during the growing season in some watersheds. Large water withdrawals will aggravate the predicted impact of climate change on river flows, particularly in the Western US. Predicted ecohydrological impacts of land cover, water withdrawal, and climate change will likely include alteration of the terrestrial water balance, stream channel habitat, riparian and aquatic community structure in snow-dominated basins, and fish and mussel extirpations in heavily impacted watersheds. These changes may also require new infrastructure to support increasing anthropogenic demand for water, relocation of agricultural production, and/or water conservation measures. Given that the impacts of land use, withdrawals and climate may be either additive or offsetting in different magnitudes, integrated and spatially explicit modeling and management approaches are necessary to effectively manage water resources for aquatic life and human use in the face of global change.

AN - 1034657960; 22839645 AB - This analysis examines wildlife poisoning from coal combustion waste (CCW) in the context of EPA's proposed policy that would allow continued use of surface impoundments as a disposal method. Data from 21 confirmed damage sites were evaluated, ranging from locations where historic poisoning has led to corrective actions that have greatly improved environmental conditions to those where contamination has just recently been discovered and the level of ecological impacts has yet to be determined. The combined direct and indirect cost of poisoned fish and wildlife exceeds $2.3 billion, which is enough money to construct 155 landfills with state-of-the-art composite liners and leachate collection systems. This cost is projected to increase by an additional $3.85 billion over the next 50 years, an amount that would construct 257 landfills. Evidence revealed through this study indicates the following: (1) for the past 45 years, environmental damage has been a recurring theme with surface impoundment of CCW, (2) the National Pollutant Discharge Elimination System has not been effective in preventing serious environmental damage from CCW, (3) EPA's Regulatory Impact Analysis of the costs and benefits of pollution control options fails to include benefits of avoided damages to natural resources, specifically, poisoned fish and wildlife, and (4) surface impoundments pose unacceptably high ecological risks regardless of location or design. Regulators should no longer ignore rigorous science and the lessons from multiple case examples. EPA and the United States need to show leadership on this issue by prohibiting surface impoundments, particularly since the rise in coal use in developing countries is leading to the same CCW pollution problems on a global scale.

17111814 AB - Estimates of consumptive use of surface water by agriculture are vital for assessing food security, managing water rights, and evaluating anthropogenic impacts on regional hydrology. However, reliable, current, and public data on consumptive use can be difficult to obtain, particularly in international and less developed basins. We combine remotely-sensed precipitation and satellite observations of evapotranspiration and groundwater depletion to estimate surface water consumption by irrigated agriculture in California's Central Valley for the 2004-09 water years. We validated our technique against measured consumption data determined from streamflow observations and water export data in the Central Valley. Mean satellite-derived surface water consumption was 291.0 plus or minus 32.4 mm/year while measured surface water consumption was 308.1 plus or minus 6.5 mm/year. The results show the potential for remotely-sensed hydrologic data to independently observe irrigated agriculture's surface water consumption in contested or unmonitored basins. Improvements in the precision and spatial resolution of satellite precipitation, evapotranspiration and gravimetric groundwater observations are needed to reduce the uncertainty in this method and to allow its use on smaller basins and at shorter time scales.

Although some work has now considered its volatile emissions from soil, there remains a lack of experimental data regarding its ability to be retained in soil and ultimately become transported with irrigation/rain waters. Using laboratory batch and soil column experiments, we aimed to better understand the phase partitioning of MeI, the ability of soils to retain MeI on the solid phase, and the potential for leaching of MeI and its primary degradation product, iodide, down a soil profile. Results indicated that MeI was retained by the solid phase of soil, being protected from volatilization and degradation, particularly in the presence of elevated organic matter. Retention was greater at lower moisture content, and maximum retention occurred after 56days of incubation. At higher moisture content, the liquid phase also became important in retaining MeI within soil. Together with low observed KD values (0.10 to 0.57mLg-1), these data suggest that MeI may be prone to leaching. Indeed, in a steady-state soil column study, initially retained MeI was transported with interstitial water. The MeI degradation product, iodide, was also readily transported in this manner. The data highlight a potentially significant process by which MeI fate and transport within the environment may be impacted.

While ranging across several climate regions, these installations all share a common experimental design with similar measurement protocols. Across all installations planted tree biomass with stem-only harvest (OM0), no compaction (C0) and chemical vegetation control (VC), ranged from 2 to 90Mgha-1. When compared with the OM0, full-tree harvest (OM1) had little consistent effect on any response variable. Full-tree harvest plus forest floor removal (OM2) also demonstrated few consistent effects on planted tree biomass, although Boreal - Great Lakes conifers showed some positive effects, reflecting high survival, but also negative effects on foliar nutrition. Compaction (C2), regardless of OM treatment, increased planted tree stand biomass consistently in Warm Humid climates, and compaction with intact forest floors (OM0C2) did so across all regions. However, most installations had medium - or coarse-textured soils and compaction did not achieve theoretical growth-limiting bulk densities. Combining OM2 with C2 resulted in lesser gains in planted tree biomass. Planted tree biomass gains with the OM0C2 were attributed largely to changes in physical soil characteristics, not to vegetation control or nutrient availability. Total stand biomass (Mgha-1) was either unaffected or, with aspen, reduced by compaction. Vegetation control (VC) consistently enhanced planted tree biomass, regardless of climate, and also enhanced foliar nutrient concentrations on Warm Humid and Mediterranean sites. VC also increased total stand biomass on sites without abundant woody competitors, but decreased it on shrub-dominated Mediterranean sites. For many of the site types and species investigated, harvest-related organic matter removal and soil compaction (excepting aspen vegetative reproduction) have not resulted in large losses in stand biomass 10year after harvest. Most stands, however, have not yet reached canopy closure, and treatment effects may continue to evolve.

AN - 1033457417; 22733821 AB - Ricin is a highly toxic protein produced by the castor plant Ricinus communis. The toxin is relatively easy to isolate and can be used as a biological weapon. There is great interest in identifying effective inhibitors for ricin. In this study, we demonstrated by three independent assays that a component of reconstituted powdered milk has a high binding affinity to ricin. We discovered that milk can competitively bind to and reduce the amount of toxin available to asialofetuin type II, which is used as a model to study the binding of ricin to galactose cell-surface receptors. Milk also removes ricin bound to the microtiter plate. In parallel experiments, we demonstrated by activity assay and by immuno-PCR that milk can bind competitively to 1 ng/ml ricin, reducing the amount of toxin uptake by the cells, and thus inhibit the biological activity of ricin. The inhibitory effect of milk on ricin activity in Vero cells was at the same level as by anti-ricin antibodies. We also found that (a) milk did not inhibit ricin at concentrations of 10 or 100 ng/ml; (b) autoclaving 10 and 100 ng/ml ricin in DMEM at 121 °C for 30 min completely abolished activity; and (c) milk did not affect the activity of another ribosome inactivating protein, Shiga toxin type 2 (Stx2), produced by pathogenic Escherichia coli O157:H7. Unlike ricin, which is internalized into the cells via a galactose-binding site, Stx2 is internalized through the cell surface receptor glycolipid globotriasylceramides Gb3 and Gb4. These observations suggest that ricin toxicity may possibly be reduced at room temperature by a widely consumed natural liquid food.
