TY - JOUR T1 - Asian Citrus Psyllid (Hemiptera: Liviidae) Tolerance to Heat AN - 1529934157; 19895835 AB - The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), is an important citrus pest because it vectors bacteria responsible for a serious citrus disease known as huanglongbing (also called citrus greening disease). We conducted research on Asian citrus psyllid heat tolerance, with special emphasis on identifying heat treatments lethal to adult Asian citrus psyllid. Working with an Asian citrus psyllid colony maintained at 27 degree C, we assessed survival of adult Asian citrus psyllid exposed to temperatures of 43-60 degree C for various durations in a laboratory oven. We found under our experimental conditions that adult Asian citrus psyllid cannot survive at 50 degree C for more than approximately 10 min and that death occurred faster at higher temperatures; males tended to be more heat-tolerant than females; young adults were less tolerant of high temperatures than older adults; adult Asian citrus psyllids predisposed to warmer temperatures were more heat-tolerant than those predisposed to cooler temperatures; and heat treatments lethal to adult Asian citrus psyllids were lethal to eggs and usually lethal to nymphs. Adult Asian citrus psyllids were less tolerant of heat treatments in the oven when the humidity level was high than when it was low. A number of heat treatments lethal to adult Asian citrus psyllid in an oven situation can be identified from the results of this research and would be useful to regulatory agencies interested in eliminating adult Asian citrus psyllids from shipments of citrus leaves destined for culinary or medicinal markets. Among a number of candidate treatments, 60 degree C for at least 10 min would be effective against all Asian citrus psyllid life stages and faster killing than lower temperatures.

STEC strains were induced to overexpress Stx2 by overnight culturing on solid agar supplemented with either ciprofloxacin or mitomycin C. Harvested cells were lysed by bead beating, and unfractionated bacterial cell lysates were ionized by MALDI. The A2 fragment of the A subunit and the mature B subunit of Stx2 were analyzed by MS/MS. Sequence-specific fragment ions were used to identify amino acid subtypes of Stx2 using top-down proteomic analysis using software developed in-house at the U.S. Department of Agriculture (USDA). Stx2 subtypes (a, c, d, f, and g) were identified on the basis of the mass of the A2 fragment and the B subunit as well as from their sequence-specific fragment ions by MS/MS (postsource decay). Top-down proteomic identification was in agreement with DNA sequencing of the full Stx2 operon (stx2) for all strains. Top-down results were also compared to a bioassay using a Vero-d2EGFP cell line. Our results suggest that top-down proteomic identification is a rapid, highly specific technique for distinguishing Stx2 subtypes.

AN - 1520381471; 19641365 AB - Field and laboratory studies were performed to determine the phenology of flight activity and the thermal requirements for adult emergence of Sirex noctilio.Degree-day (DD) accumulation from egg to adult was measured in bolts of Pinus sylvestris infested with eggs from laboratory-reared adults. Adult emergence was similarly monitored in bolts from trees that were naturally infested in the field by wild populations of S. noctilio reared at constant temperature.Laboratory-infested bolts produced mostly males, whereas field-collected material produced a 2.7 : 1 male-biased sex ratio. Mean DDs to emergence was 1477.0 plus or minus 13.4 (males) in laboratory-infested bolts, as well as 1455.2 plus or minus 11.2 (males) and 1577.8 plus or minus 19.5 (females) in field-collected material.Field-trapping studies were conducted to compare flight activity with rearing data. Trap captures showed first flight activity and peak catch occurred at 709 and 1145 DDs. The resulting degree-day model predicts early flight activity in early to mid-April for pine stands in southeastern U.S.A., early to mid-May in the Mid-Atlantic region, and late June to early July in the northeast.

201435347 AB - This article is concerned with the creation, by the Russian colonial administration, Russian researchers and photographers/artists, of a corpus of 'historical monuments' of Samarkand in the first decades after the conquest of the city. It uses travelogues, administrative reports, memoirs, the periodical press and artistic productions to determine the mechanism of selection of representative monuments, defined as the 'cultural heritage' of Russian Turkestan and, indirectly, of the Russian Empire. The internal logic of 'patrimonialization', initiated from above and ideologically engaged, becomes more obvious when it is juxtaposed against native understandings of the significance of monuments, European practices, and the political projects of the Russian Empire.

Large and consistent reductions in the concentration of these organisms demonstrates an effective and well-controlled production process. Nevertheless, it is unclear to what degree concentrations of indicator organisms are related to pathogenic organisms such as Campylobacter and Salmonella on a sample-by-sample basis. If a strong correlation exists between the concentrations of different organisms, then the monitoring of indicator organisms would be a cost-effective surrogate for the measurement of pathogenic organisms. Calculating the correlation between the concentrations of an indicator and pathogenic organism is complicated because microbial testing datasets typically contain a large proportion of censored observations (i.e., samples where the true concentration is not observable, with nondetects and samples that are only screen-test positive being examples). This study proposes a maximum likelihood estimator that can be used to estimate the correlation between the concentrations of indicator and pathogenic organisms. An example based on broiler chicken rinse samples demonstrates modest, but significant positive correlations between the concentration of the indicator organism GEC when compared to the concentration of both Campylobacter and Salmonella. A weak positive correlation was also observed between concentrations of Campylobacter and Salmonella, but it was not statistically significant.

Three different agricultural chemical pollutant mixture conditions were assessed: nutrients only (N and P); pesticides only (atrazine, S-metolachlor and permethrin); and a mixture of nutrients and pesticides. With nutrients only, 672 h nutrient mitigation of 77-91% total phosphorous (TP) and 74-98% total nitrogen (TN) was associated with distance from the injection point and rainfall, whereas with nutrient and pesticide mixtures, 672 h nutrient mitigation of 11-71% TP and 84-98% TN were associated with distance and time. With pesticides only, 672 h pesticide mitigation of 50-99% was associated with distance and time, whereas with nutrients and pesticide mixtures, 672 h pesticide mitigation of 48-99% was associated primarily with distance. Dissipation half-lives were 2-10 times greater for P and 1.5-5 times greater for N when pesticides were present. Pesticide dissipation half-lives showed no clear differences with or without nutrients. While vegetated free water surface constructed wetlands can be effective best management practice tools to trap and abate agricultural run-off during rainfall events, efficiencies can be affected by different types of complex pollutant mixtures and wetland design and implementation should accommodate varying efficiencies.

Since all adjuvants to be used in organic agriculture production are required to meet these standards, OMRI's certified list of products is a convenient starting point when developing organic pest control formulations. In the current study, six OMRI-certified surfactants are tested for their compatibility with three common entomopathogens: Beauveria bassiana, Metarhizium brunneum and Isaria fumosorosea. The fungi were evaluated in two common propagule forms, solid-state produced conidia and liquid-media produced blastospores. The results show that most of the surfactants are compatible with the fungi at a high surfactant concentration (2% w/v). In general, the conidia showed a higher susceptibility (greater reduction in spore germination) to the surfactants than the blastospores under these conditions. In addition, the surface tension and foaming properties of the surfactants were determined.

To increase our understanding on the effect of long-term poultry litter (PL) application on soil AC pools and turnover, in this study, we determined the contents of 21 ACs in 23 PL samples, 15 soil samples collected from 0-20, 20-40, and 40-60 cm layers of five pasture plots with 0, 5, 10, 15 and 20 years of PL applications, and 5 grass shoot samples grown on these pasture fields. The contents of 21 ACs were simultaneously determined by methanesulfonic acid hydrolysis/extraction and anion chromatography-pulsed amperometry. PL application increased soil total and individual AC contents with a distribution pattern similar to that of AC in PL. The highest AC-N concentrations were observed in the soils with 10- or 15-year PL applications, inconsistent with the order of annual application rates or cumulative applied PL amounts. Application of PL increased the AC contents in grass shoots whereby the highest increase of most ACs was with the shoots from the fields that received PL for 5 years. These observations suggested that both freshly applied and residual PL had contributions to the soil AC-N, and that PL application also accelerated AC-N transformation in soil.

Isolates were compared using 16S rRNA gene sequencing, repetitive sequence-based polymerase chain reaction (rep-PCR), and phenotypic microarrays. Analysis of 16S rRNA gene sequences revealed high sequence identity in these Bacteroides; with distinct phylogenetic groupings by bacterial species but not host origin. Phenotypic microarray analysis demonstrated these Bacteroides shared the ability to utilize many of the same carbon substrates, without differences due to species or host origin, indicative of their broad carbohydrate fermentation abilities. Limited nitrogen substrates were utilized; in addition to ammonia, guanine, and xanthine, purine derivatives were utilized by most isolates followed by a few amino sugars. Only rep-PCR analysis demonstrated host-specific patterns, indicating that genomic changes due to coevolution with host did not occur by mutation in the 16S rRNA gene or by a gain or loss of carbohydrate utilization genes within these Bacteroides. This is the first report to indicate that host-associated genomic differences are outside of 16S rRNA gene and carbohydrate utilization genes and suggest conservation of specific bacterial species with the same functionality across mammalian hosts for this Bacteroidetes clade. Isolates from the Bacteroides thetaiotaomicron-ovatus-xylanisolvens clade were found in fecal enrichments from mammals of differing digestive physiology, both ruminant and monogastric. These Bacteroides isolates were able to utilize a wide range of the carbon substrates but very few of the nitrogen substrates examined. The rep-PCR analysis indicated that the isolates' genomes had been altered by the host environment to some degree but genomic differences carbohydrate utilization genes. This is the first report to suggest conservation of specific bacterial species with the same functionality across mammalian hosts for this Bacteroidetes clade.

As economic entities, agricultural cooperatives may be among the few institutions in rural areas retaining a semblance of economic democratic governance. However, institutionalization processes have left many of these co-ops in a challenged position to sustain their own democratic ethos. The nature of these losses is difficult to understand without historical texture and outside a tension frame of reference. This essay will define co-op structure in a manner that specifies some of these tensions and their historical context and pressures, and make suggestions for a more inclusive and possibly more resilient cooperative alternative in the form of multistakeholder cooperatives.

The TSEB was revised recently using the Penman-Monteith equation to replace the Priestley-Taylor formulation, thus better accounting for the impact of large and varying vapor pressure deficits (VPD) typical of advective, semiarid climates. This study is a comparison of the Priestley-Taylor and Penman-Monteith versions of the TSEB (termed TSEB-PT and TSEB-PM, respectively). Both time scaling methods were not very sensitive to the T[subR] measurement time used, although morning (9:45 CST) T[subR] measurement times did not perform as well as the other times.

It is theoretically possible to enhance the current practice of visually inspecting fields for fecal material prior to harvest by using imaging to detect the fluorescence response of fecal material to UV excitation. For field application, an expanded-beam pulsed laser and a gated-intensified camera can be used for imaging to negate problems due to reflected ambient light masking fluorescent responses. To validate the homogenizing optics, images were acquired using both homogenizing optics and a simple optics system that did not incorporate a lightpipe.

As such, controlling these two variables may yield an ideal product with engineered properties -- a "designer biochar." The potential for a designer biochar comes from its ability to combine the properties of manure-based biochars, which are nutrient-rich and alkaline, with lignocellulosic biochars, which are carbon-rich and neutral to acidic. In this study, two such feedstocks (poultry litter and switchgrass) were blended at different ratios, pelletized, and then subjected to slow pyrolysis at different temperatures and to create test biochars. Even though blended biochar pellets degrade more rapidly during handling and storage, blending manure and plant material for biochar production alleviates some of the other application issues when using pure manure-based biochars for soil improvement or energy conversion applications.

Distributed stream temperature models are crucial for providing insights into variations of stream temperature for regions and time periods for which observed data do not exist. This study uses a relatively new stream temperature model incorporated into a modified version of the Soil and Water Assessment Tool (SWAT) in order to simulate stream temperatures at five sites on the Calapooia River within the Calapooia basin in northwest Oregon. The Nondominated Sorting Genetic Algorithm II (NSGA-II) is used to calibrate flow at a single outlet and stream temperatures at five sites. Few studies have calibrated this stream temperature model for different basins, and this is the first demonstration of an automatic, subbasin-level calibration for stream temperature at multiple sites. The subbasin calibration is shown to better match the observed data than the original SWAT temperature model as well as the modified temperature model calibrated basinwide. In addition to providing improved stream temperature simulations for the Calapooia River, the subbasin-level automatic calibration technique extends the applicability of the model, especially for complex basins with large spatial variability of topography, land use, and soil type.

Global interest in sustainable management of limited freshwater supplies to meet increased food demand has resulted in increased reporting of ET measurement and modeling methods in the literature. Direct measurements of ET by large weighing lysimeters are commonly used to test other ET measurement and estimation methods. Numerous studies have emphasized the importance of proper lysimeter design and management for accurate ET measurement. However, equally important and noticeably absent from the literature are guidelines for data collection, processing, analysis, and quality assurance and quality control (QA/QC) measures. Examples used in the study demons trate that indiscriminate application of smoothing functions, misidentification, and misinterpretation of changes in lysimeter mass can lead to significant errors and erroneous conclusions. Understanding and prudent application of the presented techniques and QA/QC procedures can help to minimize errors in processing lysimeter datasets.

Rev. Microbiol. 59: 155 - 189). Bacteriomes of psyllids (Hemiptera: Psylloidea) primarily consist of 2 tissue types: bacteriocytes which house an obligate symbiont 'Candidatus Carsonella ruddii,' and multinucleate syncytia which may harbor facultative symbionts (Chang and Musgrave 1969, Tissue Cell 1: 597 - 606; Fukatsu and Nikoh 1998, Appl. Environ. Microbiol. 64: 3,599 - 3606; Subandiyah et al. 2000, Zool. Sci. 17:983 - 989). A long-term goal of our research is to investigate the ecological interactions among agriculturally-important psyllids, their host plants, and bacteriome-associated symbionts, and to investigate the potential role of bacteriomes in the acquisition and transmission of psyllid-vectored plant pathogens. To facilitate the control of biological variation in future studies of bacteriomes and bacteriome-associated symbionts, the objective of our study was to provide morphological descriptions of bacteriomes from 2 agriculturally-important psyllids, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) and Cacopsylla pyricola (Forster) (Hemiptera: Psyllidae), and to compare the size and appearances of bacteriomes between sexes. A third psyllid species, Aphalara calthae L. (Hemiptera: Aphalaridae), representing a family distinct from those of the 2 pest species, was included in our comparisons to provide a systematically broad description of psylloid bacteriomes. Identification of bacterial symbionts was beyond the scope of this initial study and was not included as an objective.

Subaqueous soils could play an important role in nutrient cycling, algae blooms, the spread of invasive aquatic vegetation, and water quality. The objectives of this study were to (a) characterize some of the morphological, physical and chemical properties of subaqueous soils in Missisquoi Bay based on ground-penetrating radar and soil analysis; and (b) assess relationships among the subaqueous soil landscapes, radar facies, and submersed aquatic vegetation. Coarse Stratified Sediments and Lacustrine Silt radar facies associated with Delta/Nearshore and Lakebed/Bay Bottom subaqueous soil-landscape units covered 90 percent of the study area. The Lacustrine Silt radar facies occurred in relatively deep, low-energy, depositional areas and had the highest P concentrations. The majority of the submersed aquatic vegetation was associated with Delta/Nearshore and Fringing Peatland subaqueous soil landscapes under shallow water.

Although CSM have been widely used, they are not suitable to meet growing demands for high resolution soil information at field scales. We present a repeatable method to disaggregate CSM data into ~30-meter resolution rasterized soil class maps that include continuous representation of probabilistic map uncertainty. Methods include training set creation for original CSM component soil classes from soil-landscape descriptions within the original survey database. Training sets are used to build a random forest predictive model utilizing environmental covariate maps derived from ASTER satellite imagery and the USGS National Elevation Dataset. Results showed agreement at 70 percent of independent field validation sites and equivalent accuracy between original CSM map units and the disaggregated map. Uncertainty of predictions was mapped by relating prediction frequencies of the random forest model and success rates at validation sites.

Private companies fund nearly all food processing research and development (R&D) and perform a growing share of production-oriented R&D for agriculture. In addition, institutional partnerships for public-private research collaboration are growing in the United States and other countries. This article outlines the major forces driving these changes and offers an interpretive framework to explore some of the implications for the volume and nature of research performed by the public and private sectors. One of the critical issues is whether public agricultural research complements and thereby stimulates additional private agricultural R&D investments. Another important issue concerns the role and contribution of alternative public-private partnership arrangements. To date, changes in the institutional structure of public and private agricultural research have outpaced systematic investigation, and new theoretical and empirical research is needed to help guide policy and address key societal challenges, such as climate change, clean energy, water scarcity, food safety, and health.

Recently, in response to concerns that the overuse of antibiotics in livestock could promote the development of antimicrobial drug-resistant bacteria, the U.S. Food and Drug Administration adopted a strategy to phase out the use of antibiotics for production purposes. This study uses a stochastic frontier model and data from the 2009 USDA Agricultural Resource Management Survey of feeder-to-finish hog producers to estimate the potential effects on hog output and output variability resulting from a ban on antibiotics used for growth promotion. We use propensity score nearest neighbor matching to create a balanced sample of sub-therapeutic antibiotic (STA) users and nonusers. We estimate the frontier model for the pooled sample and separately for users and non-users-which allows for a flexible interaction between STA use and the production technology. Point estimates for the matched sample indicate that STA use has a small positive effect on productivity and production risk, increasing output by 1.0-1.3% and reducing the standard deviation of unexplained output by 1.4%. The results indicate that improvements in productivity resulted exclusively from technological improvement rather than from an increase in technical efficiency.

We evaluated effects of selective deer browsing on tree species abundance in an old-growth mesic/wet-mesic forest in central Illinois by repeated sampling of permanent study plots in 2003 and 2008 and relating changes in stem density between the two samples to the intensity of deer browsing of individual species. The study site has high deer density (75 deer km2) during winter months, and initial observations indicated that paw paw (Asimina triloba (L.) Dunal) was strongly avoided as browse. Paw paw density increased in the seedling stratum between the two sample periods. However, nearly all other tree species declined in density; blue ash (Fraxinus quadrangulata Michx.) - a low-use browse species, had a small increase in seedling density. Tree species diversity decreased in the seedling stratum, but not in the sapling stratum, although sapling density declined for some species. The current trajectory of tree species growth and recruitment suggests that the development of a dense paw paw understory canopy will further decrease species diversity and reduce tree species recruitment. Based on the life history traits of paw paw, and high deer densities and selective browsing, this issue is of concern for current and future forest communities.

Root:Shoot Ratio AN - 1534821388; 19988967 AB - A study was conducted at Akron, CO, USA, on a Weld silt loam in 2004 to quantify the effects of water deficit stress on corn ( Zea mays , L.) root and shoot biomass. Corn plants were grown under a range of soil bulk density and water conditions caused by previous tillage, crop rotation, and irrigation management. Water deficit stress (D sub(stress)) was quantified by the number of days when the water content in the surface 0.3 m deviated from the water content range determined by the Least Limiting Water Range (LLWR). Root and shoot samples were collected at the V6, V12, and R1 growth stages. There was no significant correlation between D sub(stress) and shoot or root biomass at the V6 growth stage. At the V12 and R1 growth stages, there were negative, linear correlations among D sub(stress) and both root biomass and shoot biomass. The proportional decrease of shoot biomass was greater than the proportional decrease in root biomass, leading to an increase in the root:shoot ratio as water deficit stress increased at all growth stages. Determining restrictive soil conditions using the LLWR may be useful for evaluating improvement or degradation of the soil physical environment caused by soil management.

Despite its importance, very little is known about B. cockerelli stylet probing behaviors that control transmission of Lso to its host plants. Herein, we report the first study characterizing the electrical penetration graph waveforms representing stylet penetration behaviors of the B. cockerelli feeding on potato. Waveforms produced by adult B. cockerelli on potato were also correlated using light microscopy of salivary sheath termini in plant tissue after probes were artificially terminated during the identified waveforms. In addition, behavioral activities were inferred based on electrical origins of waveforms as well as similarities in waveform appearances with those of other psyllids, aphids, and whiteflies. Adult B. cockerelli produced six waveform families and four types, which represent the following proposed biological meanings: family A, initial penetration and sheath salivation; family B, penetration of epidermal cells; family C, secretion of most of the salivary sheath and stylet pathway in mesophyll and parenchyma, with two types, C1 and C2, of unknown meaning; family D, initial contact with phloem cells; family E, activities in phloem cells, with two types, El, putative phloem salivation, and E2, phloem sap ingestion; and family G, xylem ingestion. In addition, a previously unreported variant of waveform G was characterized and correlated with applied signal type. Variation in D and G waveform appearances was correlated with polarity, type, and magnitude of applied signal. Results suggest that active phloem sap ingestion during E2 may play a critical role in acquisition of Lso bacterial cells. E1 may be important in inoculation of the bacterium into phloem sieve elements because it may represent salivation into phloem sieve elements. Analysis of B. cockerelli waveforms could lead to faster development of resistant host plant varieties, strengthen integrated pest management strategies by incorporating alternative plant hosts, and maximize the efficiency of pesticides.

Rattus rattus, the Black Rat (Rodentia: Muridae) AN - 1529929303; 19843230 AB - The black rat, roof rat, or ship rat (Rattus rattus L.) is among the most widespread invasive vertebrates on islands and continents, and it is nearly ubiquitous on Pacific islands from the equatorial tropics to approximately 55 degrees latitude north and south. It survives well in human-dominated environments, natural areas, and islands where humans are not present. Rattus rattus is typically the most common invasive rodent in insular forests. Few vertebrates are more problematic to island biota and human livelihoods than R. rattus; it is well known to damage crops and stored foods, kill native species, and serve as a vector for human diseases. Rattus rattus is an omnivore, yet fruit and seed generally dominate its diet, and prey items from the ground to the canopy are commonly at risk and exploited as a result of the prominent arboreal activity of R. rattus. Here we review the biology of this invasive species and its impacts on humans and the insular plants and animals in the Pacific. We also describe some of the past management practices used to control R. rattus populations on islands they have invaded.

(Hemiptera: Coreidae), disperse at crop-to-crop interfaces to feed on bolls in cotton. The main objective of this study was to determine whether insecticide-free tropical milkweed (Asclepias curassavica L.), a nectar-producing plant, can increase parasitism of these bugs by Trichopoda pennipes (F.) (Diptera: Tachinidae) and provide nectar to monarch butterflies and insect pollinators in these farmscapes. Peanut- cotton plots with and without flowering milkweed plants were established in 2009 and 2010. Adult T. pennipes, monarch butterflies, honey bees, and native insect pollinators readily fed on floral nectar of milkweed. Monarch larvae feeding on milkweed vegetation successfully developed into pupae. In 2009, N. viridula was the primary host of T. pennipes in cotton, and parasitism of this pest by the parasitoid was significantly higher in milkweed cotton (61.6%) than in control cotton (13.3%). In 2010, parasitism of N. viridula, C. hilaris, and L. phyllopus by T. pennipes was significantly higher in milkweed cotton (24.0%) than in control cotton (1.1%). For both years of the study, these treatment differences were not owing to a response by the parasitoid to differences in host density, because density of hosts was not significantly different between treatments. In conclusion, incorporation of milkweed in peanut- cotton plots increased stink bug parasitism in cotton and provided nectar to insect pollinators and monarch butterflies.

The transmission of antibiotic resistant S. aureus (ARSA), especially methicillin-resistant S. aureus, between food products and humans has become a serious problem. Hence, it is necessary to monitor S. aureus through the food supply chain. In this study, the disk diffusion method and epsilometer test were performed to determine the prevalence of ARSA in 78 foodborne isolates using 18 antibiotics. The highest resistance frequency was found for penicillin G (74.4%), followed by erythromycin (59.0%) and clindamycin (44.9%), whereas no vancomycin-resistant isolates were found. The 78 isolates could be subtyped into 31 resistance profiles and 11 clusters based on their antimicrobial susceptibility. Furthermore, Polymerase chain reaction (PCR) screening for the presence of 13 genes conferring antibiotic resistance was conducted. The presence of resistance genes was relatively high: blaTEM (80.8%), ermB (41.0%), grlA (38.5%), ermC (35.9%), and aac6'/aph2" (35.9%). The incidence of antibiotic resistance was significantly correlated to food types (p = 0.018), with isolates from meat and raw milk more resistant to antibiotics than those from frozen food and vegetables. The antibiotic resistance of S. aureus has become a serious concern in foodstuffs and varies in different foods. Raw milk and meat have more resistant isolates than those from frozen food and vegetables.

With a strong economic foundation, and broad coverage of economic activity, computable general equilibrium models have proven useful for analysis of alternative climate change policies. However, embedding energy technologies in a general equilibrium model is a challenge, especially for a negative emissions technology with joint products of electricity and carbon dioxide storage. We provide a careful implementation of bio-electricity with CCS in a general equilibrium context, and apply it to selected EMF-27 mitigation scenarios through 2100. Representing bio-electricity and its land requirements requires consideration of competing land uses, including crops, pasture, and forests. Land requirements for bio-electricity start at 200 kilohectares per terawatt-hour declining to approximately 70 kilohectares per terwatt-hour by year 2100 in scenarios with high bioenergy potential.

The biotic-to-abiotic shift occurs where encroachment propagates connectivity of runoff processes and amplified cross-scale erosion that, in-turn, promote ecohydrologic resilience of the post-encroachment community. We investigated these relationships for woodland-encroached sagebrush steppe in the Great Basin, USA, and evaluated wildfire as a mechanism to reverse the post-encroachment soil erosion feedback. We measured vegetation, soil properties, and runoff/erosion from experimental plots on burned and unburned areas of a late-succession woodland 1 and 2years post-fire. Our findings suggest that the biotic-to-abiotic shift and amplified cross-scale erosion occur where encroachment-induced bare ground exceeds 50-60% and bare gaps between plant bases frequently extend beyond 1m. The trigger for amplified cross-scale erosion is formation of concentrated flow within the degraded intercanopy between trees. Burning in this study decreased ecohydrologic resilience of the late-succession woodland through herbaceous recruitment 2years post-fire. Increased intercanopy herbaceous productivity decreased connectivity of bare ground, improved infiltration, and reduced erosion, but the study site remained vulnerable to runoff and erosion from high-intensity rainfall. We conclude that burning can reduce woodland ecohydrologic resilience and that woodland encroachment-induced structural and functional ecohydrologic attributes may persist during high-intensity storms for an undetermined period post-fire. We cannot conclude whether wildfire reverses the woodland-induced soil erosion feedback on sagebrush rangelands. However, our results suggest that wildfire may provide a restoration pathway for sagebrush steppe by reducing woodland ecohydrologic resilience over time. Published 2013.

The spatially explicit process model Forest-DeNitrification-DeComposition (DNDC) was used to estimate forest carbon dynamics in this region, including the effects of disturbance on carbon stocks. Model evaluation using observations from 276 sample plots in a tropical dry forest in the Yucatan Peninsula indicated that Forest-DNDC can be used to simulate carbon stocks for this forest with good model performance efficiency. The simulated spatial variability in carbon stocks was large, ranging from 5 to 115 Mg carbon (C)ha super(-1), with a mean of 56.6 Mg C ha super(-1). Carbon stocks in the forest were largely influenced by human disturbances between 1985 and 2010. Based on a comparison of the simulations with and without disturbances, carbon storage in the year 2012 with disturbance was 3.2 Mg C ha super(-1), lower on average than without disturbance. The difference over the whole study area was 154.7 Gg C, or an 8.5 % decrease. There were substantial differences in carbon stocks simulated at individual sample plots, compared to spatially modeled outputs (200 m super(2) plots vs. polygon simulation units) at some locations due to differences in vegetation class, stand age, and soil conditions at different resolutions. However, the difference in the regional mean of carbon stocks between plot-level simulation and spatial output was small. Soil CO sub(2) and N sub(2)O fluxes varied spatially; both fluxes increased with increasing precipitation, and soil CO sub(2) also increased with an increase in biomass. The modeled spatial variability in CH sub(4) uptake by soils was small, and the flux was not correlated with precipitation. The net ecosystem exchange (NEE) and net primary production (NPP) were nonlinearly correlated with stand age. Similar to the carbon stock simulations, different resolutions resulted in some differences in NEE and NPP, but the spatial means were similar.

Compounds structurally related to each of the fermentation products acetic acid, ethanol, ethyl acetate, and 2-phenethyl alcohol were screened for attractiveness compared with a soap water control in greenhouse cage bioassays. The compounds determined to be attractive in the greenhouse bioassay (methanol, ethanol, propanol, formic acid, acetic acid, ethyl acetate, propyl acetate, phenethyl acetate, phenethyl propionate, and phenethyl butyrate) were individually tested in the field added to apple cider vinegar (ACV). The acids were also tested individually in neutralized ACV (NACV; pH approximately 7). Combinations of the compounds were tested in NACV. The capture numbers in ACV traps were not significantly increased by the addition of any of the compounds tested, although significant deterrent effects of some of the compounds allowed differences between treatments to be observed. Compounds that are most prevalent in wine and vinegar (methanol, ethanol, acetic acid, and ethyl acetate) as well as phenethyl propionate and phenethyl butyrate were less deterrent than the other compounds tested in the field. Captures during peak fruit ripeness were compared with the postharvest period when fruit hosts were not available or were overripe. Although the total number of flies captured late in the season was lower, the trends in treatment performance were similar, indicating a consistent performance of these baits from peak fruit ripeness through postharvest.

Pear ester, acetic acid, and N-butyl sulfide are among those chemicals reported to attract or enhance attractiveness to codling moth. We evaluated the trapping of codling moth with N-butyl sulfide alone and in combination with acetic acid and pear ester in apple orchards. Acetic acid was attractive in two tests and N-butyl sulfide was attractive in one of two tests. N-Butyl sulfide increased catches of codling moth when used with acetic acid to bait traps. N-Butyl sulfide also increased catches of codling moth when added to traps baited with the combination of acetic acid and pear ester. Male and female codling moth both responded to these chemicals and chemical combinations. These results provide a new three-component lure comprising N-butyl sulfide, acetic acid, and pear ester that is stronger for luring codling moth females than other attractants tested.

When rehydrated, these MS granules germinate to produce conidia that can infect susceptible insects. Fermentation media containing cottonseed or soy flours as nitrogen sources and formulated at two carbon to nitrogen ratios (C:N), 30:1 or 50:1, were evaluated for production of microsclerotia. Dry MS granule samples were compared for storage stability based on conidia production, and insecticidal activity against larvae of the lesser mealworm, Alphitobius diaperinus (Panzer), using a potting soil bioassay. Cottonseed and soy flours were equivalent for production, MS granule viability, and insecticidal activity. Fermentation media containing higher nitrogen concentrations (30:1 C:N) resulted in greater biomass accumulation and greater production of conidia from granules regardless of the nitrogen source. MS granules made with M. brunneum cultures grown in media with 30:1 C:N produced 8.5 109 conidia per gram of granules after 8-d incubation, significantly higher than MS granules made using fungus produced using 50:1 C:N media (5.5 109 conidia per gram dry MS granules). The LC50 for larval mortality was 8.05 105 conidia per cup, equivalent to applications of 94 or 147 mu g granules per cup for granules made from high and low nitrogen media, respectively. Measurements of water activity were not significantly different among granule samples (0.28-0.29) even though granules made from high nitrogen media had higher moisture content (>5.2%) compared with granules made from low nitrogen media (<4.6%). Higher initial conidial production was reflected in longer storage stability at 25 degree C, with half-lives estimated at 3.7 and 1.7 wk for 30:1 and 50:1 C:N ratios, respectively.

This germplasm has not been extensively employed in US breeding programmes due to the lack of phenotypic and genetic characterization. Therefore, 68 accessions from Zimbabwe were phenotyped, and evaluated for their anthracnose response for two consecutive years, and genetically characterized with 21 simple sequence repeat markers. Phenotypic analysis showed significant differences among accessions with plant height and panicle length being the most variable traits. Likewise, 25 accessions were anthracnose resistant, nine showed variable responses and 34 were susceptible. Genetic analysis identified 174 alleles with an average of 8.3 alleles and 11.8 genotypes per locus and a polymorphic information content of 0.60. These results reflect a moderate genetically diverse germplasm. Neighbour-joining clustering analysis revealed that the majority of anthracnose-resistant accessions showed high genetic relatedness; therefore, this germplasm might represent one to six new sources of resistances. Results presented herein show that the Zimbabwe collection contains valuable germplasm for breeding programmes and is an important source of anthracnose resistance.

Little information exists regarding foraging resource selection by bats during the maternity season. We evaluated support for effects of landcover type, landform, and landscape pattern on resource selection by individual foraging female eastern red bats (Lasiurus borealis) during the maternity period and compared resource utilization for all individuals pooled (population level), individuals grouped by geographic location, and individuals grouped by stage of lactation (early, mid, and late). We used a resource utilization function (RUF) to relate landcover and landscape attributes to the utilization distributions of individual bats estimated by the fixed-kernel method. We radio-tracked 64 lactating red bats and estimated utilization distributions for 52 individuals. Mean home range size ranged from 1,041 to 1,588ha from late to mid lactation. The global RUF model was significantly better than the null RUF model for 36 (70%) individuals and the magnitude and direction of coefficients varied among individuals. Resource utilization at the population level was, on average, positively related to ridges and upland drainage landforms, water landcover, and road density; and negatively related to urban and nonforest landcover and distance to edge. Resource use differed between geographic areas by canopy cover, water landcover, and road density. Canopy closure was positively related to RUF in both areas but was greater in the south area. Percent water negatively related to RUF in the north area and positively related in the south area. Road density had a positive relationship in the north and negative relationship in the south with RUF. We did not find a difference in mean RUF coefficients among lactation groups except for canopy cover. On average, canopy cover had a positive effect on use by bats during early and mid-lactation but a negative effect during late lactation. We suggest that management for red bats consider landscape components and provide a range of composition and structural diversity to enhance foraging use by red bats. In highly forested landscapes, gaps or openings may provide forest edges that are important for foraging and commuting. Published 2014.

To reduce the likelihood of plant pest movement with WPM, the International Standard for Phytosanitary Measures No. 15: "Regulation of Wood Packaging Material in International Trade" (ISPM 15) was developed in the framework of the International Plant Protection Convention. To be compliant with this Standard, WPM shipped internationally must be either heat-treated or fumigated, regardless of any specific characteristics of the WPM. The objective of this survey was to determine if Bursaphelenchus xylophilus (Nematoda: Parasitaphelenchidae) or insects, especially Monochamus spp. (Coleoptera: Cerambycidae), were present in a specific subset of softwood boxes. While not compliant with ISPM 15, these boxes had been treated with wood preservatives, stored indoors for over five years, and, in addition to meeting various quality standards, almost all had a moisture content below 20 percent. United States Department of Agriculture staff inspected a sample of 630 softwood boxes, focusing on those showing signs of possible pest infestation. Based on a binomial distribution with an efficacy of detection equal to 0.95, a sample size of 630 provides a 95 percent confidence of detecting pests if >0.5 % of boxes are infested. No B. xylophilus or insect pests were found in the boxes, though other nematode genera (Aphelenchoides, Aphelenchus, and Filenchus), which feed on decomposing fungi in wood and do not damage trees, were found in 21 boxes. This study demonstrates that not all types of WPM present a high phytosanitary risk. It may be worthwhile to consider an amendment to ISPM 15 to differentiate between various risk categories of WPM in order to minimize costs and environmental impacts associated with treatments currently prescribed in ISPM 15.Original Abstract: Le bois d'emballage est une filiere importante de dissemination des organismes nuisibles exotiques. Pour reduire le risque de presence d'organismes nuisibles aux vegetaux dans le bois d'emballage, la Norme Internationale pour les Mesures Phytosanitaires N degree 15: > (NIMP 15) a ete developpee dans le cadre de la Convention Internationale pour la Protection des Vegetaux (CIPV). Pour etre en conformite avec cette norme, le bois d'emballage utilise dans les echanges internationaux doit obligatoirement etre traite par chauffage ou par fumigation, quelles que soient les caracteristiques de ce bois. L'objectif de cette etude etait de determiner si Bursaphelenchus xylophilus (Nematoda: Parasitaphelenchidae) ou des insectes, en particulier des Monochamus spp. (Coleoptera: Cerambycidae), etaient presents dans un lot precis de boites en bois de coniferes. Bien que n'etant pas conformes a la NIMP 15, ces boites avaient ete traitees avec des produits de conservation du bois, stockees en interieur pendant cinq ans, et avaient presque toutes une humidite relative inferieure a 20 pourcent, en plus de satisfaire plusieurs normes de qualite. Les inspecteurs de l'USDA ont controle un echantillon de 630 boites, en apportant une attention particuliere a celles qui presentaient les signes d'une infestation possible. En se basant sur une distribution binomiale avec une efficacite de la detection egale a 0,95, un echantillon de 630 boites permet de detecter une proportion de boites infestees greater than or equal to a 0,5% avec un intervalle de confiance de 95%. Aucun B. xylophilus ou autres insectes nuisibles n'ont ete identifies dans les boites, bien que d'autres genres de nematodes (Aphelenchoides, Aphelenchus, et Filenchus) qui se nourrissent de champignon de decomposition du bois et ne nuisent pas aux arbres, ont ete trouves dans 21 boites. Cette etude demontre que tous les types de bois d'emballage ne presentent pas un risque phytosanitaire eleve. Il pourrait etre opportun d'envisager une modification de la NIMP 15 pour differencier les bois d'emballage selon des categories de risque different, afin de minimiser les couts et l'impact environnemental associe aux traitements actuellement requis par la NIMP 15.

AN - 1519261988; 24406273 AB - Nanotechnology is an innovative approach that has potential applications in nutraceutical research. Phytochemicals have promising potential for maintaining and promoting health, as well as preventing and potentially treating some diseases. However, the generally low solubility, stability, bioavailability and target specificity, together with the side effects seen when used at high levels, have limited their application. Indeed, nanoparticles can increase solubility and stability of phytochemicals, enhance their absorption, protect them from premature degradation in the body and prolong their circulation time. Moreover, these nanoparticles exhibit high differential uptake efficiency in the target cells (or tissue) over normal cells (or tissue) through preventing them from prematurely interacting with the biological environment, enhanced permeation and retention effect in disease tissues and improving their cellular uptake, resulting in decreased toxicity, In this review, we outline the commonly used biocompatible and biodegradable nanoparticles including liposomes, emulsions, solid lipid nanoparticles, nanostructured lipid carriers, micelles and poly(lactic-co-glycolic acid) nanoparticles. We then summarize studies that have used these nanoparticles as carriers for epigallocatechin gallate, quercetin, resveratrol and curcumin administration to enhance their aqueous solubility, stability, bioavailability, target specificity and bioactivities.

frog control AN - 1516765935; 19445384 AB - We examined potential exposure of Hawaiian hoary bats (Lasiurus cinereus semotus) to citric acid, a minimum risk pesticide registered for control of invasive Eleutherodactylus frog populations. Hoary bats are nocturnal insectivores that roost solitarily in foliage, federally listed as endangered, and are endemic to Hawaii. Oral ingestion during grooming of contaminated fur appears to be the principal route by which these bats might be exposed to citric acid. We made assessments of oral toxicity, citric acid consumption, retention of material on fur, and grooming using big brown bats (Eptesicus fuscus) as a surrogate species. We evaluated both ground application and aerial application of 16 % solutions of citric acid during frog control operations. Absorbent bat effigies exposed to ground and aerial operational spray applications retained means of 1.54 and 0.02 g, respectively, of dry citric acid, although retention by the effigies was much higher than bat carcasses drenched in citric acid solutions. A high dose delivered orally (2,811 mg/kg) was toxic to the big brown bats and emesis occurred in 1 bat dosed as low as the 759 mg/kg level. No effect was observed with the lower doses examined ( less than or equal to 542 mg/kg). Bats sprayed with 5 ml of 16 % (w/w) citric acid solution showed no evidence of intoxication. In field situations, it is unlikely that bats would be sprayed directly or ingest much citric acid retained by fur. Based on our observations, we believe Hawaiian hoary bats to be at very low risk from harmful exposure to a toxic dose of citric acid during frog control operations.

Although quantitative (real-time) reverse transcription-PCR (qRT-PCR) is widely used for detecting HuNoVs, it only detects the presence of viral RNA and does not indicate viral infectivity. Human blood group antigens (HBGAs) have been identified as receptors/co-receptors for both HuNoVs and Tulane virus (TV) and are crucial for viral infection. We propose that viral infectivity can be evaluated with a molecular assay based on receptor-captured viruses. In this study, we employed TV as an HuNoV surrogate to validate the HBGA-based capture qRT-PCR method against the 50% tissue culture infectious dose (TCID50) method. We employed type B HBGA on an immuno-well module to concentrate TV, followed by amplification of the captured viral genome by in situ qRT-PCR. We first demonstrated that this in situ capture qRT-PCR (ISC-qRT-PCR) method could effectively concentrate and detect TV. We then treated TV under either partial or full inactivation conditions and measured the remaining infectivity by ISC-qRT-PCR and a tissue culture-based amplification method (TCID50). We found that the ISC-qRT-PCR method could be used to evaluate virus inactivation deriving from damage to the capsid and study interactions between the capsid and viral receptor. Heat, chlorine, and ethanol treatment primarily affect the capsid structure, which in turns affects the ability of the capsid to bind to viral receptors. Inactivation of the virus by these methods could be reflected by the ISC-qRT-PCR method and confirmed by TCID50 assay. However, the loss of the infectivity caused by damage to the viral genome (such as that from UV irradiation) could not be effectively reflected by this method. Despite this limitation, the ISC-qRT-PCR provides an alternative approach to determine inactivation of Tulane virus. A particular advantage of the ISC-qRT-PCR method is that it is also a faster and easier method to effectively recover and detect the viruses, as there is no need to extract viral RNA or to transfer the captured virus from magnetic beads to PCR tubes for further amplification. Therefore, ISC-qRT-PCR can be easily adapted for use in automated systems for multiple samples.

We evaluated whether or not such a fertility gradient exists for Rosa multiflora Thunb., a nonnative invasive shrub, and Kalmia latifolia L., a native problem shrub, in closed-canopy forests of the eastern U.S. Methods: We sampled soil and vegetation at the regional scale, along four randomly located 1-km transects in 70+ year-old undisturbed forests in each of three national forests in Ohio, Pennsylvania and West Virginia. We also sampled soil, vegetation and leaf tissue at the local scale, from ten individual shrubs of each species in each national forest. Results: Regional analyses showed a significant fertility gradient with Ohio being the most fertile and West Virginia the least. Soil fertility was associated with pH (most acidic in West Virginia and least acidic in Ohio) and elevation (highest in West Virginia and lowest in Ohio). At the local level, R. multiflora was associated with soil Ca:Al ratios greater than 0.5, and K. latifolia was associated with Ca:Al ratios less than 0.3. Rosa multiflora foliage contained higher concentrations of Ca, Mg, and K than K. latifolia, while K. latifolia foliage contained higher concentrations of Mn and Zn. Conclusions: Our research documents the importance of soil fertility as a predictor of the establishment of invasive and expansive shrubs. This study further shows that R. multiflora can establish and spread across a broader range of soil conditions than K. latifolia.

Virgin GWSS females deposit non-fertilized eggs and mated females can exhaust sperm reserves for egg fertilization. However, nothing is known about Gonatocerus spp. performance when using non-fertilized GWSS eggs as hosts. Host age preference for oviposition and suitability of non-fertilized GWSS eggs as hosts for G. morrilli reproduction were investigated to determine whether non-fertilized eggs on sentinel plants could be used to monitor egg parasitoid populations. Gonatocerus morrilli parasitized all ages of GWSS eggs (1-8 days old) regardless if the host egg was fertilized or not. In choice tests (fertilized versus non-fertilized eggs), parasitoids failed to emerge as adults from non-fertilized eggs more often than from fertilized eggs. The results indicate that non-fertilized eggs were accepted by G. morrilli as suitable hosts for oviposition, but were less suitable for immature development compared to fertilized eggs.

We examined indirect effects of the invader Bromus tectorum (cheatgrass) on seed fates of two native grass species, Elymus elymoides and Pseudoroegneria spicata, by removing B. tectorum and by adding inoculum of the shared seed pathogen Pyrenophora semeniperda in factorial experiments at xeric and mesic field sites. We also included a supplemental watering treatment to increase emergence and also the potential for pathogen escape. We recorded emergence and survival of native seedlings and also determined the fate of unemerged seeds. At the xeric site, Pyrenophora-caused mortality was high (34 %), and effects of other pathogens and failed emergence of germinants were smaller. Cheatgrass removal negatively affected both emergence (35 vs. 25 %) and spring survival (69 vs. 42 %). Pyrenophora-caused seed mortality increased with inoculum augmentation for both species (22 vs. 47 % overall), but emergence was negatively impacted only for P. spicata (20 vs. 34 %). At the mesic site, Pyrenophora-caused mortality was low (6 %). Cheatgrass removal doubled emergence (26 vs. 14 %). Seed mortality increased significantly with inoculum augmentation for P. spicata (12 vs. 5 %) but not E. elymoides, while emergence was not significantly affected in either species. A large fraction of seeds produced germinants that failed to emerge (37 %), while another large fraction (35 %) was killed by other pathogens. We conclude that facilitation by cheatgrass at the xeric site but interference at the mesic site was probably mediated through litter effects that could be ameliorative or suppressive. Apparent competition between cheatgrass and native grasses could occur through Pyrenophora, especially in a xeric environment, but effects were weak or absent at emergence. This was probably because Pyrenophora attacks the same slow-germinating fraction that is subject to pre-emergence mortality from other causes, including attack by other pathogens such as Fusarium.

AN - 1511822512; 24508651 AB - Two studies were conducted to understand sperm cryosensitivity in an endangered equid, the Przewalski's horse (Equus ferus przewalski), while testing the cryoprotectant ability of formamides. The first assessed the toxicity of permeating cryoprotectants (glycerol, methylformamide [MF] and dimethylformamide [DMF]) to Przewalski's horse spermatozoa during liquid storage at 4°C. The second examined the comparative influence of three diluents (with or without formamides) on cryosurvival of sperm from the Przewalski's versus domestic horse. When Przewalski's horse spermatozoa were incubated at 4°C in INRA 96 with differing concentrations of glycerol, MF or DMF or a combination of these amides, cells tolerated all but the highest concentration (10% v/v) of MF alone or in combination with DMF, both of which decreased (P0.05) between the Przewalski's (67%, 84%, respectively) and domestic (66%, 76%) horse donors. Sperm from both species were diluted in lactose-EDTA-glycerol (EQ), Botu-Crio (BOTU; a proprietary product containing glycerol and MF) or SM (INRA 96 plus 2% [v/v] egg yolk and 2.5% [v/v] MF and DMF) and then frozen over liquid nitrogen vapor. After thawing, the highest values recovered for total and progressive sperm motility, acrosomal integrity and mitochondrial membrane potential were 42.4%, 21.8%, 88.7% and 25.4CN (CN=mean JC-1 fluorescence intensity/cell on a channel number scale), respectively, in the Przewalski's and 49.3%, 24.6%, 88.9% and 25.8CN, respectively, in the domestic horse. Although sperm progressive motility and acrosome integrity did not differ (P>0.05) among treatments across species, mitochondrial membrane potential was higher (P<0.05) in both species using EQ compared to BOTU or SM media. Additionally, Przewalski's stallion sperm expressed higher (P<0.05) post-thaw total motility in BOTU and SM compared to EQ, whereas there were no differences among freezing diluents in the domestic horse. In summary, Przewalski's stallion sperm benefit from exposure to either MF or DMF as an alternative cryoprotectant to glycerol. Overt sperm quality appears similar between the Przewalski's and domestic horse, although the total motility of cells from the former appears more sensitive to certain freezing diluents. Nonetheless, post-thaw motility and acrosomal integrity values for Przewalski's horse spermatozoa mimic findings in the domestic horse in the presence of INRA 96 supplemented with 2% (v/v) egg yolk and a combined 2.5% concentration of MF and DMF.

AN - 1510711578; 24492542 AB - Shiga-toxigenic Escherichia coli, such as E. coli O157:H7, are foodborne zoonotic pathogens that can cause severe illness and death in humans. The gastrointestinal tract of ruminant animals has been identified as a primary habitat for E. coli O157:H7 and, in cattle, the hindgut tract appears to be a primary site for colonization. This pathogen has been found in cattle feces, on cattle hides, and in the production environment, and transmission to humans has occurred as a result of consumption of contaminated ground beef, water, and produce. Interventions to reduce the pathogen at beef harvest have significantly reduced the occurrence of the pathogen, but outbreaks and recalls due to the pathogen still occur for beef products. Interventions in the feedyard before harvest have had little success, but critical control points for implementing interventions are limited compared with the beef abattoir. The percentage of animals shedding E. coli O157:H7 in the feces can be highly variable from pen to pen, and the levels in the feces can vary from animal to animal. Animals colonized and shedding E. coli O157:H7 at high levels are a small fraction of animals in a pen but are important source for transferring the pathogen amongst the penmates. Recent research has indicated that diet may greatly influence the shedding of E. coli O157:H7. In addition, diet can influence the microbiota composition of the feces. However, little is known about the interaction between the indigenous microbiota and fecal shedding of E. coli O157:H7. Understanding the influence of indigenous microbiota on the colonization and shedding of E. coli O157:H7 will provide a potential avenue for intervention in the preharvest production environment not yet exploited.

AN - 1509416466; 24500933 AB - Because of the combination of population growth and population aging, increases in the incidence of chronic neurodegenerative disorders have become a societal concern, both in terms of decreased quality of life and increased financial burden. Clinical manifestation of many of these disorders takes years, with the initiation of mild cognitive symptoms leading to behavioral problems, dementia and loss of motor functions, the need for assisted living, and eventual death. Lifestyle factors greatly affect the progression of cognitive decline, with high-risk behaviors including unhealthy diet, lack of exercise, smoking, and exposure to environmental toxins leading to enhanced oxidative stress and inflammation. Although there exists an urgent need to develop effective treatments for age-related cognitive decline and neurodegenerative disease, prevention strategies have been underdeveloped. Primary prevention in many of these neurodegenerative diseases could be achieved earlier in life by consuming a healthy diet, rich in antioxidant and anti-inflammatory phytochemicals, which offers one of the most effective and least expensive ways to address the crisis. English walnuts (Juglans regia L.) are rich in numerous phytochemicals, including high amounts of polyunsaturated fatty acids, and offer potential benefits to brain health. Polyphenolic compounds found in walnuts not only reduce the oxidant and inflammatory load on brain cells but also improve interneuronal signaling, increase neurogenesis, and enhance sequestration of insoluble toxic protein aggregates. Evidence for the beneficial effects of consuming a walnut-rich diet is reviewed in this article.

Currently, the rates of farm visitation by deer and co-use of forage resources by cattle and deer are poorly understood. To evaluate the extent deer and livestock may share forage resources, we investigated farm, yard, and cattle-use area visitation by white-tailed deer and compared visitation with common livestock management practices. We fitted 25 female white-tailed deer near the bTB-infected zone in Michigan's Lower Peninsula with global positioning system collars. Livestock management practices associated with farm visitation included presence of confined feeding pastures, number of cattle water sources, and the number of cattle pastures. Fewer farm visits occurred at night than during the day. A higher proportion of nighttime visits occurred between midnight and sunrise. Visitation to yards and cattle-use areas were similar: a higher proportion of visits occurred at night, and a higher proportion of nighttime visits occurred between midnight and sunrise. Multiple visits during the same day were common. Visitation increased through spring and peaked during the fawning season. Results suggest that mitigation and control efforts to guard against potential transmission of bTB should include the season and time of day during which deer visitation occurs. Furthermore, specific livestock management practices may contribute to farm visitation by deer. Deer visiting multiple farms may contribute to local area spread of bTB. Focusing risk mitigation efforts on individual deer that are most likely to visit farms may reduce potential bTB transmission.

In vaccine efficacy trials, Mycobacterium bovis bacillus Calmette-Guerin (BCG) administered orally reduces colonization and bTB-associated lesions in white-tailed deer after experimental challenge with virulent M. bovis. The objective of this study was to develop and evaluate the palatability of a molasses-based bait for oral delivery of BCG to white-tailed deer. Relevant practical properties of the bait such as physical stability under various environmental conditions were evaluated, as well as palatability. Captive deer consumed baits within 3 h of introduction during 48 of 50 trials. Digital game cameras revealed consumption of all placed baits by one deer over 62 % of the time. Addition of BCG vaccine did not negatively impact palatability. Physical stability analysis demonstrated that ice and water significantly reduced bait stability as measured with a compression assay. Storage of BCG-containing baits at 4 degree C showed a slight decrease in colony-forming units (CFUs) by day 31. In contrast, storage at -20 or -80 degree C over the same 31-day period showed no significant decrease in BCG viability. The results of this study suggest that molasses-based baits, as prepared here, represent a plausible means of oral delivery of BCG to white-tailed deer under most environmental conditions.

AN - 1506415611; 24389887 AB - This study compares two cultivation methods (Petri dishes vs. Phytotoxkit containers; tap water vs. Knop's solution) for standard seedling growth tests. Seeds and young seedlings of Sinapis alba and Hordeum vulgare were used as study subjects and the adverse effect of Cd was assessed. Under testing conditions, only H. vulgare showed a significant decrease in seed germination in Petri dishes when tap water was used as the growth medium (70.8 % ± 46.4 %). No significant differences in IC50 values were found in either plant type for root growth between plants cultivated in Phytotoxkit containers and those cultivated in Petri dishes. The same findings were confirmed for shoot growth in H. vulgare, but not in S. alba. Suitability of Phytotoxkit containers over traditionally used Petri dishes for phytotoxicity determination was confirmed by higher correlation coefficients for all tests.

AN - 1511391061; 24675727 AB - Sweetpotato, commercially grown in over 100 countries, is one of the ten most important staple crops in the world. Sweetpotato weevil is a major pest of sweetpotato in most areas of cultivation, the feeding of which induces production in the sweetpotato root of extremely bitter tasting and toxic sesquiterpenes which can render the sweetpotato unfit for consumption. A significant step towards improved management of this weevil species was the identification of a female-produced sex pheromone [(Z)-3-dodecenyl (E)-2-butenoate] to which males are highly attracted. Reported here are results of research that documents a nearly 5-fold increase in male sweetpotato weevil catch in traps baited with this pheromone and a green light provided by a solar-powered, light-emitting diode (LED). The combination of olfactory and night-visible visual cues significantly enhanced trap effectiveness for this nighttime-active insect species. These results provide promise for improved sweetpotato weevil detection and suppression in mass trapping programs. JF - Scientific reports AU - McQuate, Grant T AD - USDA-ARS, Daniel K.

AN - 1499126981; 24480188 AB - Crops frequently contaminated by aflatoxins are important sources of revenue and daily nourishment in many portions of sub-Saharan Africa. In recent years, reports have associated aflatoxins with diminished human health and export opportunities in many African Nations. Aflatoxins are highly carcinogenic metabolites mainly produced by members of Aspergillus sect. Flavi. The current study examined aflatoxin-producing fungi associated with maize grain intended for human consumption in 18 sub-Saharan African countries. 4469 Aspergillus sect. Flavi isolates were obtained from 339 samples. The majority (75%) of isolates belonged to the L strain morphotype of A. flavus. Minor percentages were A. tamarii (6%), A. parasiticus (1%), and isolates with S strain morphology (3%). No A. bombycis or A. nomius isolates were detected. Phylogenetic analyses of partial sequences of the nitrate reductase gene (niaD, 1.3kb) and the aflatoxin pathway transcription factor gene (aflR, 1.7kb) were used to verify isolate assignments into species and lineages. Phylogenetics resolved S strain isolates producing only B aflatoxins into two lineages fully supported by sizes of deletions in the gene region spanning the aflatoxin biosynthesis genes cypA (aflU) and norB (aflF). One lineage was the A. flavus S strain with either 0.9 or 1.5kb deletions. The second lineage, recently described from Kenya, has a 2.2kb deletion. Taxa with S strain morphology differed in distribution with strain SBG limited to West Africa and both A. minisclerotigenes and the new lineage from Kenya in Central and East Africa. African A. flavus L strain isolates formed a single clade with L strain isolates from other continents. The sampled maize frequently tested positive for aflatoxins (65%), fumonisins (81%), and deoxynivalenol (40%) indicating the presence of fungi capable of producing the respective toxins. Percentage of samples exceeding US limits for total aflatoxins (regulatory limit), fumonisins (advisory limit), and deoxynivalenol (advisory limit) were 47%, 49%, 4%, respectively.

It was reported that bacteria could be bio-accumulated mainly in the gills and digestive glands. In artificially treated oysters, bacterial communities have been investigated by culture-independent methods after harvest. However, little information is available on the seasonal dynamics of bacterial accumulation in retail oyster tissues. In this study, retail oysters were collected from local market in different seasons. The seasonal dynamics and diversity of bacteria in oyster tissues, including the gills, digestive glands and residual tissues, were analyzed by denaturing gradient gel electrophoresis (DGGE). It was interesting that the highest bacterial diversity appeared in the Fall season, not in summer. Our results indicated that Proteobacteria was the predominant member (23/46) in oyster tissues. Our results also suggested that bacterial diversity in gills was higher than that in digestive glands and other tissues. In addition, not all the bacteria collected from surrounding water by gills were transferred to digestive glands. On the other hand, few bacteria were found in oyster tissues except in the gills. Therefore, the gills could be the best candidate target tissue for monitoring of pathogenic bacteria either to human or to oyster.

In addition, once contaminated, pathogens may internalize into produce and be protected from disinfectants during the postharvest processing step. The objective of the current study was to determine the potential internalization of Escherichia coli O157:H7 into spinach roots and subsequent transfer to the edible parts. Because curli are involved in biofilm formation, we investigated whether their presence influence the internalization of E. coli O157:H7 into spinach. Further, the effect of the spinach cultivar on E. coli O157:H7 internalization was evaluated. Spinach plants were grown in contaminated soil as well as hydroponically to prevent mechanical wounding of the roots and inadvertent transfer of pathogens from the contamination source to the non-exposed plant surfaces. Results showed that E. coli O157:H7 could internalize into hydroponically grown intact spinach plants through the root system and move to the stem and leaf level. The incidence of internalization was significantly higher in hydroponically grown plants when roots were exposed to 7 log CFU/mL compared to those exposed to 5 log CFU/mL. The effect of cultivar on E. coli O157:H7 internalization was not significant (P > 0.05) for the analyzed spinach varieties, internalization incidences showing almost equal distribution between Space and Waitiki, 49.06% and 50.94% respectively. Wounding of the root system in hydroponically grown spinach increased the incidence of E. coli O157:H7 internalization and translocation to the edible portions of the plant. Experimental contamination of the plants grown in soil resulted in a greater number of internalization events then in those grown hydroponically, suggesting that E. coli O157:H7 internalization is dependent on root damage, which is more likely to occur when plants are grown in soil. Curli expression by E. coli O157:H7 had no significant effect on its root uptake by spinach plants.

An outbreak that occurred in Europe in 2011 linked to fenugreek sprouts was caused by E. coli O104:H4 that had characteristics of an enteroaggregative E. coli (EAEC) but carried the gene that encoded for Shiga toxin 2. In this study, methods were developed for detection of this enteroaggregative STEC O104, as well as STEC O104 in sprouts. The methodologies described in this study for detection of enteroaggregative STEC O104:H4 and STEC O104 include the use of immunomagnetic (IMS) and latex reagents for serogroup O104, and they enhance the ability to detect and isolate these pathogens from sprouts and potentially other foods, as well.

Although there is some recovery of function after exposure to [sup 56]Fe particles, particularly in changes observed 36 h following irradiation, long-term changes have been observed, suggesting sub-cellular damage. Therefore, berry fruits high in antioxidant and anti-inflammatory activity, such as blueberries and strawberries, may prevent the occurrence of neurochemical and behavioral changes that occur if fed prior to radiation. Irradiation with [sup 56]Fe, which causes substantial build-up of toxic cellular debris in critical regions of the brain, may overwhelm the innate antioxidant enzyme defense system. Therefore, berry diets high in antioxidants may be used to counter these damaging effects by reducing oxidative stress and inflammation, and activating neuronal housekeeping, in addition to boosting endogenous antioxidant enzymes.

To improve efficacy these herbicides are often activated by post-application irrigation. Broiler litter is commonly applied to fields before these herbicides. The herbicide wetting-in practice increases surface soil water content and may increase runoff and transport of broiler litter borne fecal bacteria into surface waters during subsequent storm events. Our objective was to determine differences in loads of fecal bacteria, Escherichia coli and Salmonella spp., in runoff from conventional tillage (CT) and no-till (NT) systems after herbicides were watered into an Ultisol fertilized with broiler litter. On replicated 6m2-plots (n=3) simulated rainfall was applied for 70min with composite runoff samples collected every 5min and analyzed for E. coli and Salmonella spp. Although total runoff volume from the CT plots was significantly greater than from NT plots, no significant differences in total load of E. coli and Salmonella or the percent of total loads of E. coli and Salmonella recovered in runoff between tillage systems were observed. Total percentage of Salmonella recovered in runoff from both tillage systems was, however, four log10 orders of magnitude greater than the percentage of E. coli that was recovered. Difference in percentage recovered between the fecal indicator bacterium, E. coli, and the pathogen, Salmonella, underscores an apparent difference in hydrologic transport characteristics of these two fecal bacteria and casts doubts on the efficacy of E. coli as an indicator of risk to public health.

This study tracked NO3-N and P in soil water under three cropping systems suited for the U.S. Midwest, including two-year (corn-soybean; 2YS), three-year (corn-soybean-small grain/red clover; 3YS), and four-year (corn-soybean-small grain/alfalfa-alfalfa; 4YS) systems. Nutrient applications were based on soil-test results, and solely comprised inorganic fertilizers to 2YS corn, whereas, in the 3YS and 4YS systems, nutrients were provided by legume residues, and a managed balance of composted manure, and inorganic fertilizers. Soil water was collected from 2004 through 2011 using suction samplers. The 4YS system had smaller concentrations of NO3-N and a lower frequency of P detection (p 0.02mgL-1) was less (p <0.05) under the 4YS system (0.26) than observed for the experiment overall (0.35), which resulted from infrequent detection (0.17) of P in soil water during the alfalfa and corn crops. Results provide evidence that rotational systems including alfalfa with annual crops and use of soil testing in nutrient management can reduce movement of N and P below the root zone.

The declining cover of natural and semi-natural habitats, in particular, has been shown to reduce natural-enemy attack of crop pests, but also in some cases reduced crop colonization by such pests. In this study, we examined the influence of changes in two elements of landscape composition, natural grassland cover and cover of a highly suitable crop host, on infestation by a generalist insect pest in wheat, and parasitism of this pest by its dominant natural enemies. Surprisingly, we found no significant influences of increasing natural grassland habitat, at either local or landscape scales, on infestation by the wheat stem sawfly, Cephus cinctus, or parasitism of this pest by the native parasitoid wasps, Bracon cephi and Bracon lissogaster. In contrast, we found significant increases in levels of C. cinctus infestation with increasing wheat cover at the landscape scale. This pattern was consistent across six study regions spanning three states in the northern Great Plains of North America, despite large differences in cropping systems and pest population densities across regions. Regional variation in pest infestation was best explained by long-term averages in precipitation, with higher C. cinctus infestation rates found in drier regions. Results suggest that landscape-mediated variation in pest pressure in this system is better explained by a direct response of pest insects to increasing cover of a highly suitable crop rather than an indirect response via reductions in natural enemies as natural habitat declines. The implication is that habitat diversification at the landscape scale could play a role in suppressing agricultural pest populations via reductions in area of suitable crop hosts.

A constructed wetland is a main component of WRSIS, and one important function of this constructed wetland is drainage water treatment of nitrogen. Four field tests were therefore conducted at a northwest Ohio WRSJS wetland to evaluate nitrate-nitrogen (NO[sub 3][sup -]-N), ammonium-nitrogen (NH[sub 4][sup +]-N), and total nitrogen (TN) removal effectiveness. Tests 1 and 2 had lower inflow water volumes, shorter effective retention times, and smaller nitrogen fertilizer input loads. Test 3 had an intermediate inflow volume, intermediate effective retention time, and an intermediate nitrogen input load, while Test 4 had a high inflow volume, long effective retention time, and a large nitrogen input load.

Thus, one can balance the production of degradation products against hemicellulose hydrolysis and therefore the enzymatic saccharification efficiency of the resultant substrate by changing pretreatment temperature and duration. Specifically, pretreatment at 165 [degrees]C for 75 min significantly reduced furan formation compared with the pretreatment at 180 [degrees]C for 30 min while maintaining the same pretreatment severity and therefore the same substrate enzymatic digestibility (SED). Obtaining high SED with Douglas-fir is also limited by lignin content. Fortunately, the bisulfite in SPORL provides delignification activity. By combining kinetic models for hemicelluloses hydrolysis, sugar degradation, and delignification, the performance of pretreatment can be optimized with respect to temperature, duration, acid, and bisulfite loading. The kinetic approach taken in this study is effective to design viable low temperature pretreatment processes for effective bioconversion of lignocelluloses.

The ongoing H5N1 HPAI epizootic that began in 1996 has also spilled over to infect wild birds. Traditional stamping-out programs in poultry have resulted in eradication of most HPAI epizootics. However, vaccination of poultry was added as a control tool in 1995 and has been used during five epizootics. Over 113 billion doses of AI vaccine have been used in poultry from 2002 to 2010 as oil-emulsified, inactivated whole AIV vaccines (95.5%) and live vectored vaccines (4.5%). Over 99% of the vaccine has been used in the four H5N1 HPAI enzootic countries: China including Hong Kong (91%), Egypt (4.7%), Indonesia (2.3%), and Vietnam (1.4%) where vaccination programs have been nationwide and routine to all poultry. Ten other countries used vaccine in poultry in a focused, risk-based manner but this accounted for less than 1% of the vaccine used. Most vaccine "failures" have resulted from problems in the vaccination process; i.e., failure to adequately administer the vaccine to at-risk poultry resulting in lack of population immunity, while fewer failures have resulted from antigenic drift of field viruses away from the vaccine viruses. It is currently not feasible to vaccinate wild birds against H5N1 HPAI, but naturally occurring infections with H5 low pathogenicity avian influenza viruses may generate cross-protective immunity against H5N1 HPAI. The most feasible method to prevent and control H5N1 HPAI in wild birds is through control of the disease in poultry with use of vaccine to reduce environmental burden of H5N1 HPAIV, and eventual eradication of the virus in domestic poultry, especially in domestic ducks which are raised in enzootic countries on range or in other outdoor systems having contact with wild aquatic and periurban terrestrial birds.

However, native plant restoration efforts often remain unguided by ecological genetic information. Given that many ecosystems are in flux from climate change, restoration plans need to account for both contemporary and future climates when choosing seed sources. In this study we analyze vegetative responses, including mortality, growth, and carbon isotope ratios in two blackbrush (Coleogyne ramosissima) common gardens that included 26 populations from a range-wide collection. This study provides the framework for delineating climate change-responsive seed transfer guidelines, which are needed to inform restoration and management planning. We propose four transfer zones in blackbrush that correspond to areas currently dominated by cool-adapted and warm-adapted ecotypes in each of the two ecoregions.

There is a need for information that can assist with locating suitable habitats in fragmented and degraded landscapes to aid the reintroduction of at-risk plant species. We examine how airborne light detection and ranging (LiDAR) data can be used to model microtopographic features that reduce water stress and increase resource availability, providing information for landscape planning that can increase the success of reintroduction efforts for a dryland landscape in Hawaii. We developed a topographic habitat-suitability model (HSM) from LiDAR data that identifies topographic depressions that are protected from prevailing winds and contrasts them with ridges and other exposed areas. among high-suitability plots. The HSM can improve the survival of planted individuals, reduce the cost of restoration and reintroduction programs through targeted management activities in high-suitability areas, and expand the ability of managers to make landscape-scale decisions regarding land-use, land acquisition, and species recovery.

AN - 1534828690; 19362968 AB - Switchgrass (Panicum virgatum L.) and big bluestem (Andropogon gerdardii Vitman) are potential perennial bioenergy feedstocks. Feedstock storage limitations, labor constraints for harvest, and environmental benefits provided by perennials are rationales for developing localized perennial feedstock as an alternative or in conjunction with annual feedstocks (i.e., crop residues). Little information is available on yield, mineral, and thermochemical properties of native species as related to harvest time. The study's objectives were to compare the feedstock quantity and quality between grasses harvested in the fall or the following spring. It was hypothesized that biomass yield may decline, but translocation and/or leaching of minerals from the feedstock would improve feedstock quality. Feedstock yield did not differ by crop, harvest time, or their interactions. Both grasses averaged 6.0 Mg ha super(-1) (fall) and 5.4 Mg ha super(-1) (spring) with similar high heating value (17.7 MJ kg super(-1)). The K/(Ca+Mg) ratio, used as a quality indicator declined to below a 0.5 threshold, but energy yield (Megajoule per kilogram) decreased 13 % by delaying harvest until spring. Only once during the four study-years were conditions ideal for early spring harvest, in contrast during another spring, very muddy conditions resulted in excessive soil contamination. Early spring harvest may be hampered by late snow, lodging, and muddy conditions that may delay or prevent harvest, and result in soil contamination of the feedstock. However, reducing slagging/fouling potential and the mass of mineral nutrients removed from the field without a dramatic loss in biomass or caloric content are reasons to delay harvest until spring.

Moving away from the traditional focus on party systems, the demographic characteristics of voters, or political socialization, I consider instead how memory and narrative shape political consciousness. Specifically, I focus on how culturally sanctioned memories of warfare influence the political attitudes of 24 Vietnam veterans. I compare two groups of Vietnam veterans who went to Vietnam in support of the war and political status quo, but who returned with opposing attitudes toward war. How can we understand these contrasting outcomes? Specifically, how do memories of war shape political attitudes? Antiwar veterans relate similar narratives of having their idealistic views of war challenged and experiencing a major rethinking of their support when they learn the true nature of warfare. On the other hand, pro-war veterans share a patterned narrative of indifference rather than idealism when describing their continued support of the war and political status quo after they return from Vietnam. I conclude by arguing that memory and narrative are an important mechanism for shaping political attitudes. Adapted from the source document.

L. asiaticus'-positive psyllid vector, Diaphorina citri. Our studies showed that 'Ca. L. asiaticus' was detectable from trees in areas with maximum temperatures reaching nearly 50[degrees]C (average maximum of 42[degrees]C). However, the bacterium was present at very low levels in psyllids both in summer (June to August) and autumn (September to November) in contrast to reports from Florida, where the bacterium was detectable at very high levels during October to November. We hypothesize that hot summer temperatures in Pakistan may interfere with acquisition and replication of 'Ca. L. asiaticus' in psyllids and may lead to dead or nontransmissible 'Ca. L. asiaticus' in plants. Psyllid counts were very low in both summer and winter, showed a population peak ('Ca. L. asiaticus'-positive vectors) in spring, and showed a larger peak ('Ca. L. asiaticus'-free psyllids) in autumn. Natural thermotherapy during hot summers and a low vector population during environmental extremes may have played a major role in long-term survival of the citrus industry in Pakistan. These results may be useful in developing management strategies for U.S. citrus industries in Texas and California.

A seasonal pattern of appearance of the psyllid in crops from southern to northern regions of the United States is well documented. Potatoes are commonly grown as winter and summer crops in southern and northern parts, respectively, of the United States. No other plant material is available for psyllids when each crop is planted, and the psyllids must migrate into each crop each season. Appearance of psyllids in potato crops commonly starts at an initial focus, often at field margins or other breaks in the canopy, such as irrigation tracks. Psyllids readily jump and fly when disturbed, providing an obvious mechanism for dispersal within a crop. Good experimental evidence also supports longer distance dispersal of potato psyllid, from tens of meters to a few kilometers, most likely by cumulative short distances between suitable host plants within a region. Seasonal infestation observations suggest annual continental-wide migration of the psyllid, although little direct experimental evidence yet exists. Mechanisms for dispersal of potato psyllid over continental distances have been proposed, largely associated with seasonal wind patterns. However, recent overwintering observations in the northern regions of its native zone in the United States and identification of geographically-defined and genetically distinct potato psyllid populations, suggest a static regional status of at least some populations. Thus, a review of migration of potato psyllid into crops is presented herein, and a new paradigm for considering overwintering strategies of potato psyllid is required.

This method differentiates the four known potato psyllid haplotypes by using restriction enzyme digestion of a portion of the mitochondrial large subunit ribosomal RNA, tRNA-Val, and a portion of the small subunit ribosomal RNA, providing a second target within the mitochondrial DNA for haplotyping studies. This technique also provides a good alternative to the current method of potato psyllid haplotyping which uses high-resolution melting analysis, a technique that requires access to a real-time PCR machine with high-resolution melting capabilities. Potato psyllid haplotyping by restriction digestion is done using basic laboratory equipment that is readily available for smaller laboratories with budgetary limitations, thereby providing an excellent tool for laboratories of all sizes to identify psyllid populations.

With a short life cycle, prolific fecundity, an arrhenotokous reproduction, and an ability to expeditiously digest and detoxify xenobiotics, twospotted spider mite has the propensity to develop resistance to insecticides. Despite mobility, small size, and difficulties associated with handling of twospotted spider mites, this study demonstrated that the 20-ml glass-vial bioassay is a useful technique to evaluate contact toxicity of acaricides against adult mites in a laboratory. A colony of twospotted spider mites was maintained on pinto beans, Phaseolus vulgaris L. in a greenhouse. Abamectin with LC50 (95% CL) of 0.014 (0.01-0.02) mu g per vial was 1,006 time more toxic than spiromesifen with a LC50 of 14.086 (7.592-42.371) mu g per vial. The LC50 values of spiromesifen and propargite were comparable. Bifenazate was 10 times more toxic than dicofol to twospotted spider mite. The order of toxicity of acaricides tested against twospotted spider mite adults was abamectin > bifenazate > dicofol > propargite = spiromesifen. These data are useful for developing baseline contact toxicity for adult twospotted spider mite and monitoring tolerance to acaricides used on cotton in Central Texas.

The microbial burden of each source fiber was measured as a preliminary assessment of microbial contamination using heterotrophic spread plate counts. Greige cotton fibers exhibited the highest levels of total microbial contamination, which were reduced by both storage time and trash removal in the form of mechanical cleaning. Changes in microbial burden levels were measured at each step in the nonwoven manufacturing process. The hydroentanglement process resulted in the greatest overall reduction in microbial burden with no detectable levels of aerobic microbial contamination present on any of the final hydroentangled roll goods regardless of the source fiber. No detectable levels of aerobic microbial regrowth were observed on any fabrics despite storage time or ambient storage conditions. Analysis of suspended solids present in hydroentanglement effluents collected during fabric production revealed significantly less suspended solids from synthetic fibers compared to all cotton fiber types. The study provided insight and potential guidelines that could be incorporated into a nonwoven processing line to ensure specific sterility requirements are met for various converters in end-uses such as hygiene and medical applications.

AN - 1516757492; 19551386 AB - Differential plant use by herbivores has been observed for several woody plant species and has frequently been attributed to plant secondary metabolites. We examined the relationship between terpenoid concentration and Juniperus monosperma herbivory by small ruminants. Two groups of animals (10 goats or 5 goats plus 4 sheep) browsed 16 paddocks (2030 m) containing one-seed juniper for six days during two seasons. Juniper leaves were sampled from 311 saplings immediately after browsing. Saplings were categorized by size (short [1.0 m]), and by browsing intensity (light [66 %]). Juniper bark was collected from 12 saplings during spring. Total estimated terpenoid concentrations in leaves and bark were 18.3 plus or minus 0.3 and 8.9 plus or minus 0.8 mg/g, respectively, and the dominant terpene in both tissues was alpha -pinene (11.1 plus or minus 0.2 and 7.6 plus or minus 0.7 mg/g, respectively). Total terpenoid concentration of juniper leaves was greater in spring than summer (20.6 plus or minus 0.5 vs. 16.7 plus or minus 0.3 mg/g, respectively) and was lower in short saplings than medium or tall saplings (16.5 plus or minus 0.6 vs. 19.8 plus or minus 0.4 and 19.5 plus or minus 0.4 mg/g, respectively). Total terpenoid concentration of leaves also differed among the three defoliation categories (21.2 plus or minus 0.6, 18.7 plus or minus 0.5, and 16.1 plus or minus 0.4 mg/g for light, moderate, and heavy, respectively). The smallest subset of terpenoids able to discriminate between light and heavy browsing intensity categories included eight compounds ([E]- beta -farnesene, bornyl acetate, gamma -eudesmol, endo-fenchyl acetate, gamma -cadinene, alpha -pinene, cis-piperitol, and cis-p-menth-2-en-1-ol). Our results suggest terpenoid concentrations in one-seed juniper are related to season, sapling size, and browsing by small ruminants.

Produce Large Amounts of Aplotaxene, a Possible Allelochemical AN - 1516757058; 19551387 AB - The invasive thistle Carduus nutans has been reported to be allelopathic, yet no allelochemicals have been identified from the species. In a search for allelochemicals from C. nutans and the closely related invasive species C. acanthoides, bioassay-guided fractionation of roots and leaves of each species were conducted. Only dichloromethane extracts of the roots of both species contained a phytotoxin (aplotaxene, (Z,Z,Z)-heptadeca-1,8,11,14-tetraene) with sufficient total activity to potentially act as an allelochemical. Aplotaxene made up 0.44 % of the weight of greenhouse-grown C. acanthoides roots (ca. 20 mM in the plant) and was not found in leaves of either species. It inhibited growth of lettuce 50 % (I sub(50)) in soil at a concentration of ca. 0.5 mg g super(-1) of dry soil (ca. 6.5 mM in soil moisture). These values gave a total activity in soil value (molar concentration in the plant divided by the molarity required for 50 % growth inhibition in soil=3.08) similar to those of some established allelochemicals. The aplotaxene I sub(50) for duckweed (Lemna paucicostata) in nutrient solution was less than 0.333 mM, and the compound caused cellular leakage of cucumber cotyledon discs in darkness and light at similar concentrations. Soil in which C. acanthoides had grown contained aplotaxene at a lower concentration than necessary for biological activity in our short-term soil bioassays, but these levels might have activity over longer periods of time and might be an underestimate of concentrations in undisturbed and/or rhizosphere soil.

Dispersions of these amylose-sodium palmitate complexes prevent amylose from retrograding and possess polyelectrolyte properties due to the anionic charge of the sodium palmitate. Stable aqueous dispersions of these complexes form hydrogels when added to acid to lower the pH, and these hydrogels were used to prepare their corresponding xerogels, cryogels, and aerogels. Solvent exchange with ethanol and supercritical carbon dioxide (SC-CO sub(2)) drying of the starch gels preserved the structure of the gels and yielded aerogels having a macroporous nanoparticulate internal structure. Depressurization rates during SC-CO sub(2) drying were examined to optimize aerogel properties, and starch aerogels with densities between 0.120-0.185 g cm super(-3) and BET surface areas ranging between 313-362 m super(2) g super(-1) were obtained. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, and scanning electron microscopy (SEM), were used to characterize the aerogels. The corresponding xerogels and cryogels had inferior properties. This method provides an alternative method for the preparation of starch aerogels and eliminates many difficulties associated with starch gelatinization and retrogradation procedures that are currently used to prepare the prerequisite starch gels.

In both states, we consistently captured adult females of the digger wasp Astata occidentalis Cresson (Hymenoptera: Sphecidae) in traps with lures that contained methyl (E,E,Z)-2,4,6-decatrienoate but not in traps with lures that contained only methyl (E,Z)-2,4-decadienoate. Astata occidentalis is a predator of pentatomid stink bugs (Hemiptera) and apparently uses methyl (E,E,Z)-2,4,6-decatrienoate as a host-finding kairomone. Methyl (E,E,Z)-2,4,6-decatrienoate is an aggregation pheromone of Plauti stali Scott (Hemiptera: Pentatomidae) that is also attractive to, and used for monitoring, the exotic brown marmorated stink bug, Halyomorphahalys Stal (Hemiptera: Pentatomidae). Wasps were captured from Jul through Sep with peak response in Aug in Washington. In Georgia, wasp capture was highest as soon as traps were deployed in late May/early Jun, and then capture peaked again during Jul.

The qseC gene encodes a sensory kinase that autophosphorylates in response to AI-3, E, or NE and subsequently phosphorylates its cognate response regulator QseB. In the absence of QseC, QseB downregulates bacterial motility and virulence in animal models. In this study, we found that 8- to 10-month-old calves orally inoculated with a mixture of E. coli O157:H7 and its isogenic qseBC mutant showed significantly higher fecal shedding of the qseBC mutant. In vitro analysis revealed similar growth profiles and motilities of the qseBC mutant and the parental strain in the presence or absence of NE. The magnitudes of the response to NE and expression of flagellar genes flhD and fliC were also similar for the qseBC mutant and the parental strain. The expression of ler (a positive regulator of the locus of enterocyte effacement [LEE]), the ler-regulated espA gene, and the csgA gene (encoding curli fimbriae) was increased in the qseBC mutant compared to the parental strain. On the other hand, growth, motility, and transcription of flhD, fliC, ler, espA, and csgA were significantly reduced in the qseBC mutant complemented with a plasmid-cloned copy of the qseBC genes. Thus, in vitro motility and gene expression data indicate that the near-parental level of motility, ability to respond to NE, and enhanced expression of LEE and curli genes might in part be responsible for increased colonization and fecal shedding of the qseBC mutant in calves.

To investigate the likely performance of large trees in a rapidly changing climate, we analyzed growth rings of five conifer species against 20th century climate trends from local weather stations. Over the local station period of record, there were no temporal trends in precipitation, but maximum temperatures increased by 0.10 to 0.13 degree C/decade (summer and autumn), and minimum temperatures increased by 0.11 to 0.19 degree C/decade in all seasons. All species responded positively to precipitation, but more variation was explained by a significant positive response to minimum winter temperatures. High maximum summer temperature adversely affected growth of two species, and maximum spring temperatures in the year prior to ring formation were negatively associated with growth of one species. The strong coherent response to increasing minimum temperatures bodes well for growth of large trees in Sierra/Cascades region mixed conifer forest under continued climatic warming, but these trees will still be under threat by the increased fire intensity that is a indirect effect of warming.

In addition, a cluster of four mutations near hairpin loop-D83 improved K sub(t) super(0.5) by ~3 degree C; none of the individual amino acid changes measurably affect K sub(t) super(0.5). Saturation mutagenesis of L186 identified the variant L186K as having the most improved K sub(t) super(0.5) value, by 8.1 plus or minus 0.3 degree C. The L186Y mutation was found to be additive, resulting in K sub(t) super(0.5) increasing by up to 8.8 plus or minus 0.3 degree C when several beneficial mutations were combined. While k sub(cat) of xylobiose and 4-nitrophenyl- beta -d-xylopyranoside were found to be depressed from 8 to 83 % in the thermally improved mutants, K sub(m), K sub(ss) (substrate inhibition), and K sub(i) (product inhibition) values generally increased, resulting in lessened substrate and xylose inhibition.

The enzymes associated with this reduction process are poorly understood. In Rhizobium selenitireducens at least two enzymes are potentially involved; one, a nitrite reductase reduces SeO sub(3) super(-2) to Se super(0) but another protein may also be involved which is investigated in this study. Proteins from R. selenitireducens cells were precipitated with ammonium sulfate and run on native electrophoresis gels. When these gels were incubated with NADH and SeO sub(3) super(-2) a band of precipitated Se super(0) developed signifying the presence of a SeO sub(3) super(-2) reducing protein. Bands were cut from the gel and analyzed for peptides via LCMSMS. The amino acid sequences associated with the bands indicated the presence of an NADH:flavin oxidoreductase that resembles YP_001326930 from Sinorhizobium medicae. The protein is part of a protein family termed old-yellow-enzymes (OYE) that contain a flavin binding domain. OYE enzymes are often involved in protecting cells from oxidative stress and, due in part to an active site that has a highly accessible binding pocket, are generally active on a wide range of substrates. This report is the first of an OYE enzyme being involved in SeO sub(3) super(-2) reduction.

Geospatial technologies, particularly remote sensing, could potentially be used in these ecosystems to (1) evaluate the longevity of fuel reduction treatments, (2) provide data for planning and designing future fuel-reduction treatments, and (3) assess the spatial distribution of horizontal fuel structure following fuel-reduction treatments. High-spatial resolution color-infrared imagery (0.06-m pixels) was acquired for pinyon and juniper woodland plots where fuels were reduced by either prescribed fire, tree cutting, or mastication at five sites in Oregon, California, Nevada, and Utah. Imagery was taken with a Vexcel UltraCam X digital camera in June 2009. Within each treatment plot, ground cover was measured as part of the Sagebrush Steppe Treatment Evaluation Project. Trimble eCognition Developer was used to classify land cover classes using object-based image analysis (OBIA) techniques. Differences between cover estimates using OBIA and ground-measurements were not consistently higher or lower for any land cover class and when evaluated for individual sites, were within plus or minus 5 % of each other. The overall accuracy and the K sub(hat) statistic for classified thematic maps for each treatment were: prescribed burn 85 % and 0.81; cut and fell 82 % and 0.77, and mastication 84 % and 0.80. Although cover assessments from OBIA differed somewhat from ground measurements, they are sufficiently accurate to evaluate treatment success and for supporting a broad range of management concerns.

Such changes in sagebrush-steppe communities are occurring with invasion of annual grasses (AG) into a perennial grass (PG) dominated system. We conducted a 5-year litter manipulation study located in the northern Great Basin, USA. Springtime litter was partially or completely removed in three communities with differing levels of invasion (invaded, mixed, and native) to determine how litter removal and litter biomass affected plant-available soil N and plant community composition. Litter biomass (prior to the removal treatment) was negatively correlated with plant-available N in the invaded community, but was positively correlated in the native community. Plant-available N had greater intra- and inter-annual fluctuations in the invaded compared to the mixed or native communities, but was not generally affected by removal treatments. Litter removal had negative effects on AG cover during a warm/dry year and negative effects on PG cover during a cool/wet year in the mixed community. Overall, the effectiveness of springtime litter manipulations on plant-available N were limited and weather dependent, and only removal treatments >75 % had effects on the plant community. Our study demonstrates how communities invaded by AGs have significantly increased temporal variability in nutrient cycling, which may decrease ecosystem stability. Further, we found that the ecological impacts from litter manipulation on sagebrush communities were dependent on the extent of AG invasion, the timing of removal, and seasonal precipitation.

Stomatal behavior was characterized by relating predawn leaf water potential and mid-morning stomatal conductance to mid-morning leaf water potential. Seasonal average weekly midday leaf water potential was lower in Cabernet Sauvignon than Malbec despite similar irrigation amounts. Both cultivars exhibited anisohydric behavior with midday leaf water potential decreasing linearly with declining predawn leaf water potential (r super(2) = 0.51) and stomatal conductance (r super(2) = 0.42). However, both cultivars utilized hydrodynamic mechanisms to maintain a soil-to-leaf water potential gradient of -0.62 ( plus or minus 0.03) MPa under standard irrigation and -0.75 ( plus or minus 0.04) MPa under reduced irrigation. Berry fresh weight and titratable acidity decreased, and the concentration of total anthocyanins increased in both cultivars in response to decreases in midday leaf water potential. The slope of regression equations for seasonal mean midday leaf water potential was used to estimate cultivar-specific levels of water stress associated with changes in berry weight and berry composition at fruit maturity.

Most studies addressing virulence factors of B. bronchiseptica utilize isolates derived from hosts other than pigs in conjunction with rodent infection models. Based on previous in vivo mouse studies, we hypothesized that the B. bronchiseptica type III secretion system (T3SS) would be required for maximal disease severity and persistence in the swine lower respiratory tract. To examine the contribution of the T3SS to the pathogenesis of B. bronchiseptica in swine, we compared the abilities of a virulent swine isolate and an isogenic T3SS mutant to colonize, cause disease, and be transmitted from host to host. We found that the T3SS is required for maximal persistence throughout the lower swine respiratory tract and contributed significantly to the development of nasal lesions and pneumonia. However, the T3SS mutant and the wild-type parent are equally capable of transmission among swine by both direct and indirect routes, demonstrating that transmission can occur even with attenuated disease. Our data further suggest that the T3SS skews the adaptive immune response in swine by hindering the development of serum anti-Bordetella antibody levels and inducing an interleukin-10 (IL-10) cell-mediated response, likely contributing to the persistence of B. bronchiseptica in the respiratory tract. Overall, our results demonstrate that the Bordetella T3SS is required for maximal persistence and disease severity in pigs, but not for transmission.

AN - 1500696451; 24412484 AB - The filamentous fungus, Aspergillus flavus, produces the toxic and carcinogenic, polyketide synthase (PKS)-derived family of secondary metabolites termed aflatoxins. While analysis of the A. flavus genome has identified many other PKSs capable of producing secondary metabolites, to date, only a few other metabolites have been identified. In the process of studying how the developmental regulator, VeA, affects A. flavus secondary metabolism we discovered that mutation of veA caused a dramatic down-regulation of transcription of a polyketide synthase gene belonging to cluster 27 and the loss of the ability of the fungi to produce sclerotia. Inactivation of the cluster 27 pks (pks27) resulted in formation of greyish-yellow sclerotia rather than the dark brown sclerotia normally produced by A. flavus while conidial pigmentation was unaffected. One metabolite produced by Pks27 was identified by thin layer chromatography and mass spectral analysis as the known anthraquinone, asparasone A. Sclerotia produced by pks27 mutants were significantly less resistant to insect predation than were the sclerotia produced by the wild-type and more susceptible to the deleterious effects of ultraviolet light and heat. Normal sclerotia were previously thought to be resistant to damage because of a process of melanization similar to that known for pigmentation of conidia. Our results show that the dark brown pigments in sclerotia derive from anthraquinones produced by Pks27 rather than from the typical tetrahydronapthalene melanin production pathway. To our knowledge this is the first report on the genes involved in the biosynthesis of pigments important for sclerotial survival. Published by Elsevier Inc.

AN - 1500695153; 24361724 AB - The efficacy of attractive toxic sugar baits (ATSB) with the active ingredient eugenol, an Environmental Protection Agency exempt compound, was evaluated against vector and nuisance mosquitoes in both laboratory and field studies. In the laboratory, eugenol combined in attractive sugar bait (ASB) solution provided high levels of mortality for Aedes aegypti, Culex quinquefasciatus, and Anopheles quadrimaculatus. Field studies demonstrated significant control: >70% reduction for Aedes atlanticus, Aedes. infirmatus, and Culex nigripalpus and >50% reduction for Anopheles crucians, Uranotaenia sapphirina, Culiseta melanura, and Culex erraticus three weeks post ATSB application. Furthermore, non-target feeding of six insect orders, Hymenoptera, Lepidoptera, Coleoptera, Diptera, Hemiptera, and Orthoptera, was evaluated in the field after application of a dyed-ASB to flowering and non-flowering vegetation. ASB feeding (staining) was determined by dissecting the guts and searching for food dye with a dissecting microscope. The potential impact of ATSB on non-targets, applied on green non-flowering vegetation was low for all non-target groups (0.9%). However, application of the ASB to flowering vegetation resulted in significant staining of the non-target insect orders. This highlights the need for application guidelines to reduce non-target effects. No mortality was observed in laboratory studies with predatory non-targets, spiders, praying mantis, or ground beetles, after feeding for three days on mosquitoes engorged on ATSB. Overall, our laboratory and field studies support the use of eugenol as an active ingredient for controlling important vector and nuisance mosquitoes when used as an ATSB toxin. This is the first study demonstrating effective control of anophelines in non-arid environments which suggest that even in highly competitive sugar rich environments this method could be used for control of malaria in Latin American countries.

AN - 1500691483; 24440601 AB - Numerous plant species worldwide including some Palicourea (Rubiaceae), Tanaecium (Bignoniaceae), and Amorimia (Malpighiaceae) species in Brazil cause sudden death and are known to contain monofluoroacetate (MFA). Two species of Palicourea, Palicourea aenofusca and Palicourea marcgravii, cause sudden death and are reported to contain MFA while other Palicourea species are reported to cause sudden death in livestock and are suspected to contain MFA due to the similarity in clinical signs. Using an HPLC-APCI-MS method to detect MFA, herbarium specimens representing 46 Palicourea taxa were screened for the presence of MFA. Additionally we screened five Psychotria taxa that are closely related to Palicourea species. Ten species of Palicourea were identified that contained MFA, two previously reported and eight newly reported here; these are closely related to each other, though some other related species did not contain MFA.

AN - 1494305876; 23988561 AB - Boron (B) stress (deficiency and toxicity) is common in plants, but as the functions of this essential micronutrient are incompletely understood, so too are the effects of B stress. To investigate mechanisms underlying B stress, we examined protein profiles in leaves of Arabidopsis thaliana plants grown under normal B (30 μM), compared to plants transferred for 60 and 84 h (i.e., before and after initial visible symptoms) in deficient (0 μM) or toxic (3 mM) levels of B. B-responsive polypeptides were sequenced by mass spectrometry, following 2D gel electrophoresis, and 1D gels and immunoblotting were used to confirm the B-responsiveness of some of these proteins. Fourteen B-responsive proteins were identified, including: 9 chloroplast proteins, 6 proteins of photosynthetic/carbohydrate metabolism (rubisco activase, OEC23, photosystem I reaction center subunit II-1, ATPase δ-subunit, glycolate oxidase, fructose bisphosphate aldolase), 6 stress proteins, and 3 proteins involved in protein synthesis (note that the 14 proteins may fall into multiple categories). Most (8) of the B-responsive proteins decreased under both B deficiency and toxicity; only 3 increased with B stress. Boron stress decreased, or had no effect on, 3 of 4 oxidative stress proteins examined, and did not affect total protein. Hence, our results indicate relatively early specific effects of B stress on chloroplasts and protein synthesis. Copyright © 2013 Elsevier GmbH. All rights reserved.

19298647 AB - Purpose: Biochars are a by-product of the biofuel processing of lignocellulosic and manure feedstocks. Because biochars contain an assemblage of organic and inorganic compounds, they can be used as an amendment for C sequestration and soil quality improvement. However, not all biochars are viable soil amendments; this is because their physical and chemical properties vary due to feedstock elemental composition, biofuel processing, and particle size differences. Biochar could deliver a more effective service as a soil amendment if its chemistry was designed ex ante with characteristics that target specific soil quality issues. In this study, we demonstrate how biochars can be designed with relevant properties as successful soil amendments through feedstock selection, pyrolysis conditions, and particle size choices. Materials and methods: Biochars were produced by pyrolysis of parent lignocellulosic feedstock sources-peanut hull (PH; Archis hypogaea), pecan shell (PS; Carya illinoensis), switchgrass (SG; Panicum virgatum), pine chips (PC; Pinus taeda), hardwood wastes (wood), and poultry litter manure (PL; Gallus domesticus), as well as blends of these feedstocks at temperatures ranging from 250 to 700 degree C. Additionally, blended feedstocks were made into pellets (>2 mm) prior to pyrolysis at 350 degree C. Dust-sized (<0.42 mm) biochar was obtained through grinding of pelletized biochars. After chemical characterization, the biochars were evaluated as fertility amendments in a Norfolk soil (fine-loamy, kaolinitic, thermic, Typic Kandiudult) during two different pot incubation experiments. Results and discussion: PL biochars were alkaline and enriched in N and P, whereas biochar from lignocellulosic feedstocks exhibited mixed pH and nutrient contents. Blending PL with PC resulted in lower biochar pH values and nutrient contents. In pot experiment 1, most biochars significantly (P<0.05) raised soil pH, soil organic carbon, cation exchange capacity, and Mehlich 1 extractable P and K. PL biochar added at 20 gkg super(-1) resulted in excessive soil P concentrations (393 to 714 mgkg super(-1)) and leachate enriched with dissolved phosphorus (DP, 22 to 70 mgL super(-1)). In pot experiment 2, blended and pelletized PL with PC feedstock reduced soil pH and extractable soil P and K concentrations compared to pot experiment 1. Water leachate DP concentrations were significantly (P<0.05) reduced by pelletized biochar blends. Conclusions: Short-term laboratory pot experiments revealed that biochars can have different impacts at modifying soil quality characteristics. Keying on these results allowed for creating designer biochars to address specific soil quality limitations. In the process of manufacturing designer biochars, first, it is important to know what soil quality characteristics are in need of change. Second, choices between feedstocks, blends of these feedstocks, and their accompanying particle sizes can be made prior to pyrolysis to create biochars tailored for addressing specific soil quality improvements. Utilization of these principles should allow for effective service of the designed biochar as a soil amendment while minimizing unwanted ex facto soil quality changes and environmental effects.

Brahman bulls were selected based on temperament score. Bulls (10 months; 211 plus or minus 5 kg BW; n = 6, 8 and 7 for Calm, Intermediate and Temperamental groups, respectively) were fitted with indwelling jugular catheters to evaluate peripheral blood concentrations of glucose, blood urea nitrogen (BUN), non-esterified fatty acids (NEFA), insulin, epinephrine and cortisol before and after LPS administration (0.5 mu g/kg BW LPS). Feed intake was also recorded. Intermediate bulls consumed more feed than the Temperamental bulls during the challenge (p= 0.046). Pre-LPS glucose (p= 0.401) and BUN (p= 0.222) did not differ among the temperament groups. However, pre-LPS insulin (p= 0.023) was lower, whereas pre-LPS NEFA (p< 0.001), cortisol (p< 0.001) and epinephrine (p< 0.001) were greater in Temperamental than in Calm and Intermediate bulls. Post-LPS glucose was increased in Calm and Intermediate bulls but not in Temperamental bulls (p< 0.001). Insulin concentrations post-LPS were greater in Calm than in Intermediate and Temperamental bulls (p< 0.001). Concentrations of NEFA post-LPS were greater in Temperamental than in Calm and Intermediate bulls (p< 0.001). Serum BUN concentration increased post-LPS, with values being greater in Calm and Intermediate than in Temperamental bulls (p= 0.012). Collectively, these data demonstrate that animal temperament is related to the metabolic responses of Brahman bulls following a provocative endotoxin challenge. Specifically, Temperamental bulls may preferentially utilize an alternate energy source (i.e. NEFA) to a greater degree than do bulls of Calm and Intermediate temperaments. The use of circulating NEFA from lipolysis may reduce the negative metabolic consequences of an immune response by allowing for a prompt answer to increasing energy demands required during immunological challenge, compared with the time required for glycogenolysis and gluconeogenesis.

As more land becomes slated for urban development, identifying effective urban forest wildlife management tools becomes paramount to ensure the urban forest provides habitat to sustain bird and other wildlife populations. The primary goal of this study was to integrate wildlife suitability indices to an existing national urban forest assessment tool, i-Tree. We quantified available habitat characteristics of urban forests for ten northeastern U.S. cities, and summarized bird habitat relationships from the literature in terms of variables that were represented in the i-Tree datasets. With these data, we generated habitat suitability equations for nine bird species representing a range of life history traits and conservation status that predicts the habitat suitability based on i-Tree data. We applied these equations to the urban forest datasets to calculate the overall habitat suitability for each city and the habitat suitability for different types of land-use (e.g., residential, commercial, parkland) for each bird species. The proposed habitat models will help guide wildlife managers, urban planners, and landscape designers who require specific information such as desirable habitat conditions within an urban management project to help improve the suitability of urban forests for birds.

Although an increased reliance on solar energy will likely benefit airports from environmental and economic perspectives, bird use of solar installations should be examined before wide-scale implementation to determine whether such changes in land use adversely affect aviation safety by increasing risk of bird-aircraft collisions. We studied bird use of five pairs of PV arrays and nearby airport grasslands in Arizona, Colorado, and Ohio, over one year. Across locations, we observed 46 species of birds in airfield grasslands compared to 37 species in PV arrays. We calculated a bird hazard index (BHI) based on the mean seasonal mass of birds per area surveyed. General linear model analysis indicated that BHI was influenced by season, with higher BHI in summer than fall and winter. We found no effect of treatment (PV arrays vs. airfields), location, or interactions among predictors. However, using a nonparametric two-group test across all seasons and locations, we found greater BHI in airfield grasslands than PV arrays for those species considered especially hazardous to aircraft (species greater than or equal to 1.125kg). Our results suggest that converting airport grasslands to PV arrays would not increase hazards associated with bird-aircraft collisions.

The objectives of this research were to determine baseline particulate matter (PM) concentrations around the immediate barn perimeter and to identify relationships between management practices and PM concentrations. PM was measured over two five-day periods at one pack system barn to determine differences in PM concentration between routine operation and a bedding event. The overall mean concentration of total suspended particulates (TSP) in the pack barn was 58.6 + or -3.9 mu g m super(-3) during routine operation and 702.2 + or -3.9 mu g m super(-3) during bedding events. The mean concentrations of PM less than 10 mu m in diameter (PM sub(10)) and PM less than 2.5 mu m in diameter (PM sub(2.5)) were 4.9 + or -3.0 mu g m super(-3) and 17.5 + or -12.1 mu g m super(-3), respectively, during routine operation and 29.7 + or -4.6 mu g m super(-3) and 141.7 + or -18.9 mu g m super(-3), respectively, during a bedding event. The PM concentrations returned to baseline within 18 h following a bedding event. In two scrape system barns, 24 h collections of PM sub(10) and PM sub(2.5) occurred at least twice during each quarter during a 14-month period. Daily mean concentrations of PM sub(2.5) and PM sub(10) in the scrape barns ranged from 10 to 14 mu g m super(-3) and from 25 to 28 mu g m super(-3), respectively, indicating relatively low PM concentrations from mono-slope beef facilities. Ambient air temperature affected PM concentration, while relative humidity, number of cattle, and wind speed were less influential on overall dust in the facilities.

Occasional poor performance of the WEPS erosion submodel (Single-event Wind Erosion Evaluation Program, or SWEEP) in simulating small amounts of erosion of loessial soils, which contribute to poor air quality in the Columbia Plateau region of the U.S. Pacific Northwest, has been partly attributed to overestimation of threshold friction velocity (u* sub(t)). Few studies have been conducted to improve the poor performance of the SWEEP in this region. Therefore, the objective of this study was to test the performance of the SWEEP in simulating the occurrence of erosion when the simulated u* sub(t) (SWEEP u* sub(t)) was replaced with measured values of u* sub(t) or with estimates of u* sub(t) derived from algorithms used in the Lu and Shao model, Shao model, Texas Tech Erosion Analysis Model (TEAM), and Wind Erosion on European Light Soils (WEELS) model. The occurrence of erosion from agricultural lands was better estimated by the SWEEP when SWEEP u* sub(t) was replaced with the u* sub(t) algorithm used in the Lu and Shao model. However, soil loss was better estimated by the SWEEP when using SWEEP u* sub(t) rather than the measured u* sub(t) or other u* sub(t) algorithms. Since prediction of both the occurrence and magnitude of wind erosion is important to overall model performance, there is a need to further improve the SWEEP in the Columbia Plateau and other regions where small amounts of erosion can impact soil resources and environmental quality.

The aim of this study was to develop a real-time quantitative polymerase chain reaction (qPCR) assay for detection of airborne inoculum of P. effusa in California. Among oomycete rihosomal DNA (rDNA) sequences examined for assay development, the highest nucleotide sequence identity was observed between rDNA sequences of P. effusa and P. schachtii, the cause of downy mildew on sugar beet and Swiss chard in the leaf beet group (Beta vulgaris subsp. vulgaris). Single-nucleotide polymorphisms were detected between P. effusa and P. schachtii in the 18S rDNA regions for design of P. effusa- and P. schachtii-specific TaqMan probes and reverse primers. An allele-specific probe and primer amplification method was applied to determine the frequency of both P. effusa and P. schachtii rDNA target sequences in pooled DNA samples, enabling quantification of rDNA of P. effusa from impaction spore trap samples collected from spinach production fields. The rDNA copy numbers of P. effusa were, on average, [approximate]3.300-fold higher from trap samples collected near an infected field compared with those levels recorded at a site without a nearby spinach field. In combination u ilh disease-conducive weather forecasting, application of the assays may be helpful to time fungicide applications for disease management.

Effects on watermelon are devastating, with total vine collapse, often near harvest, and fruit rendered unmarketable by brown, discolored flesh. The epidemiology of SqVYV was studied in a I-ha field of `Fiesta' watermelon over six growing seasons (Ito VI) to characterize the spatial patterning of disease and temporal rate of disease progress, as well as its association with Cucurbit leaf crumple virus (CuLCrV) and Cucurbit ye/low stunting disorder virus (CYSDV), two additional whitefly-transmitted viruses that often occur with SqVYV. Results of this study provide epidemiological information that will be useful in the development of management strategies for SqVYV-induced vine decline, and provide new information for CuLCrV and CYSDV.

These viruses co-occur in regions where maize is grown, such that co-infections are likely. Co-infection of different strains of MCDV is also observed, and a synergistic enhancement of symptoms in co-infected plants was previously reported. Here, we examined the impact of co-infections of two strains of MCDV (MCDV-S and MCDV-M1, severe and mild, respectively), and co-infections of MCDV and MDMV in the sweet com hybrid 'Spirit' in greenhouse experiments. Quantitative plant growth and development parameters were measured and vims accumulation was measured by reverse-transcriptase quantitative polymerase chain reaction.

Group I has recently been described as a new cryptic species, B. pseudocinerea (4). Gray mold caused by B. cinerea is a major postharvest disease of blueberries in the Central Valley of California. In 2012 and 2013, blueberry fruit were sampled at harvest from various locations in the region and stored at 0 to 1[degrees]C for 5 weeks, and fungi were isolated from decayed fruit. In total, 526 isolates of Botrytis spp. were obtained.

The objectives of this study were to determine which Phytophthora species are involved in root rot, examine the efficacy of different isolation methods (cane, root, and root/soil baiting with young raspberry plants), and determine if pathogenicity, fungicide resistance, and/or genetic variation exists among P. rubi isolates collected from raspberry fields in Washington, Oregon, and California. Of 275 samples, direct isolation from cane material resulted in a greater number of P. rubi isolates (39%), whereas root/soil baiting yielded the least (11%). Sequencing of the internal transcribed spacer region of 210 of the total 597 collected Phytophthora isolates showed that all but one isolate (identified as P. bisheria) were P. rubi. Results of the pathogenicity and fungicide resistance to mefenoxam comparing 14 total isolates from Washington, Oregon, and California showed that isolates were similarly virulent against red raspberry and the EC sub(50) frequency distributions showed no significant difference. These results, combined with amplified fragment length polymorphism results show that P. rubi isolates from Washington, Oregon, and California represent one large mixed population. This work provides novel insights into the isolation and biology of P. rubi in western U.S. raspberry production systems.

Before disturbance, half-hourly daytime NEE during full sunlight conditions, daily GEP, and daily WUEe during the summer months were greater at the oak-dominated stand compared to the mixed or pine-dominated stands. Both defoliation by gypsy moth and prescribed burning reduced stand leaf area and nitrogen mass in foliage. During complete defoliation in 2007 at the oak stand, NEE during full sunlight conditions and daily GEP during the summer averaged only 14 and 35% of pre-disturbance values. Midday NEE and daily GEP then averaged 58 and 85%, and 71 and 78% of pre-defoliation values 1 and 2 years following complete defoliation, respectively. Prescribed fires conducted in the dormant season at the mixed and pine-dominated stands reduced NEE during full sunlight conditions and daily GEP during the following summer to 57 and 68%, and 79 and 82% of pre-disturbance values, respectively. Daily GEP during the summer was a strong function of N mass in foliage at the oak and mixed stands, but a weaker function of N in foliage at the pine-dominated stand. Ecosystem WUEe during the summer at the oak and mixed stands during defoliation by gypsy moth averaged 1.6 and 1.1 g C kg H2O-1, representing 60 and 46% of pre-disturbance values. In contrast, prescribed fires at the mixed and pine-dominated stands had little effect on WUEe. Two years following complete defoliation by gypsy moth, WUEe during the summer averaged 2.1 g C kg H2O-1, 80% of pre-disturbance values. WUEe was correlated with canopy N content only at the oak-dominated stand. Overall, our results indicate that WUEe during and following non-stand replacing disturbance is dependent on both the type and time since disturbance.

AN - 1642613981; 21154599 AB - The honey bee hive environment contains a rich microbial community that differs according to niche. Acetobacteraceae Alpha 2.2 (Alpha 2.2) bacteria are present in the food stores, the forager crop, and larvae but at negligible levels in the nurse and forager midgut and hindgut. We first sought to determine the source of Alpha 2.2 in young larvae by assaying the diversity of microbes in nurse crops, hypopharyngeal glands (HGs), and royal jelly (RJ). Amplicon-based pyrosequencing showed that Alpha 2.2 bacteria occupy each of these environments along with a variety of other bacteria, including Lactobacillus kunkeei. RJ and the crop contained fewer bacteria than the HGs, suggesting that these tissues are rather selective environments. Phylogenetic analyses showed that honey bee-derived Alpha 2.2 bacteria are specific to bees that "nurse" the hive's developing brood with HG secretions and are distinct from the Saccharibacter-type bacteria found in bees that provision their young differently, such as with a pollen ball coated in crop-derived contents. Acetobacteraceae can form symbiotic relationships with insects, so we next tested whether Alpha 2.2 increased larval fitness. We cultured 44 Alpha 2.2 strains from young larvae that grouped into nine distinct clades. Three isolates from these nine clades flourished in royal jelly, and one isolate increased larval survival in vitro. We conclude that Alpha 2.2 bacteria are not gut bacteria but are prolific in the crop-HG-RJ-larva niche, passed to the developing brood through nurse worker feeding behavior. We propose the name Parasaccharibacter apium for this bacterial symbiont of bees in the genus Apis.

This study addressed those challenges by measuring and modeling selected soil profile properties of paired (native) forest and analogous nonnative (cultivated) loess hillslopes in central Missouri. The paired hillslopes in Saline County were mapped as Mollic Hapludalfs and the paired hillslopes in Boone County were mapped as Typic Hapludalfs. Horizonation and depth distribution of Hapludalf soil properties provide markers when measuring land use impacts on soil profile properties. Summit pedons on the four sites verified the mapping and classification. Transect data revealed soil profile variation by slope position and by site. Regression analysis identified relationships at the p < 0.007 level between depth to clay maximum (adjusted R (super 2) = 0.74), thickness of the A horizon (adjusted R (super 2) = 0.32), thickness of the subsurface horizon (adjusted R (super 2) = 0.69), depth to the top of the B horizon (adjusted R (super 2) = 0.69), clay content of the surface horizon (R (super 2) = 0.76), organic C content of the surface horizon (adjusted R (super 2) = 0.56), and depth to < or =7.5 g kg (super -1) organic C (adjusted R (super 2) = 0.59) and slope position and site characteristics. A different response surface for each site for each soil characteristic supported the hypothesis that vegetative history and land use significantly affected the distribution of these soil properties.

A system developed for sequentially using saline drainage water for supplemental irrigation resulted in significant reduction of the drainage water volume. This system dubbed 'integrated on-farm drainage management' (IFDM) was demonstrated on four 65-ha fields located on a farm on the west side of the San Joaquin Valley of California. Three of the fields were used to grow salt-sensitive crops (tomato, garlic) and the fourth was used to grow salt-tolerant crops, e.g. 'Jose' tall wheatgrass. Subsurface drainage systems were installed on all fields at a maximum depth of 1.8m and had controls to regulate shallow water table position and drainage flow. The total drainage flow from the site represented 0.7% of the applied water. The area used for salt-tolerant crops was less than 6% of the total area served, compared to using evaporation ponds requiring areas equal to or greater than 10% of the served area. The results demonstrated that the regional groundwater quality masked the concentrating effect of crop water use. Deep percolation from the fields contributing to the reuse area ranged from 6 to 10% of the total applied water. Published 2013.

Ce systeme baptise Gestion integree du drainage a la ferme (IFDM) a ete demontre sur quatre champs de 65ha situes sur une ferme sur le cote ouest de la vallee de San Joaquin en Californie. Trois de ces domaines ont ete utilises pour cultiver des plantes sensibles au sel (tomate, ail) et le quatrieme a ete utilise pour cultiver des plantes tolerantes au sel, par exemple 'Jose' tall wheat grass. Les systemes de drainage souterrains ont ete installes sur toutes les parcelles, a une profondeur maximale de 1.8m et avaient les infrastructures necessaires pour regler la position de la nappe phreatique et le debit de drainage. Le debit restitue par le drainage represente 0.7% de l'eau utilisee. La superficie allouee aux cultures tolerantes au sel etait inferieure a 6% de la superficie totale desservie, alors que le recours aux bassins d'evaporation aurait necessite des superficies egales ou superieures a 10% de la zone desservie. Les resultats ont demontre que la qualite des eaux souterraines regionales a masque l'effet de la concentration des eaux de drainage due a la consommation d'eau des cultures.

Invasive plants can alter the quality of breeding habitat for songbirds, thereby impacting important demographic traits such as dispersal, philopatry, and age structure. These demographic effects may in turn alter song-learning conditions to affect song structure and diversity. We studied Chipping Sparrows (Spizella passerina) breeding in six savannas that were either dominated by native vegetation or invaded by spotted knapweed (Centaurea stoebe), an exotic forb known to diminish food resources and reproductive success. Here, we report that the prevalence of older birds was relatively low in knapweed-invaded habitat, where recruitment of yearlings compensated for diminished site fidelity to sustain territory abundance. In both habitat types, yearling males tended to adopt songs similar to their neighbors and match the songs of older birds rather than introducing new song types, a pattern seen in many songbird species. As a consequence, in invaded habitat where age structure was skewed away from older birds serving as potential song models, yearlings converged on fewer song types. Similarity of songs among individuals was significantly higher and the overall number of song types averaged nearly 20% lower in invaded relative to native habitat. Degradation of habitat quality generally impacts site fidelity and age ratios in migratory songbirds and hence may commonly alter song-learning conditions. Associated shifts in song attributes known to influence reproductive success could in turn enforce demographic declines driven by habitat degradation. Local song structure may serve as an important indicator of habitat quality and population status for songbirds.

Differences in trait values between native and exotic invasive species, however, should not be considered fixed and may depend on the context of the comparison. Furthermore, the magnitude of difference between native and exotic species necessary to trigger invasion is unknown. We propose a criterion that differences in trait values between a native and exotic invasive species must be greater than differences between co-occurring natives for this difference to be ecologically meaningful and a contributing factor to plant invasion. We used a meta-analysis to quantify the difference between native and exotic invasive species for various traits examined in previous studies and compared this value to differences among native species reported in the same studies. The effect size between native and exotic invasive species was similar to the effect size between co-occurring natives except for studies conducted in the field; in most instances, our criterion was not met although overall differences between native and exotic invasive species were slightly larger than differences between natives. Consequently, trait differences may be important in certain contexts, but other mechanisms of invasion are likely more important in most cases. We suggest that using trait values as predictors of invasion will be challenging.

Infection by these two pathogens occurs in the orchard but remains latent before harvest. Symptoms develop aller harvest and are similar to those of gray mold caused by Botrytis cinerea. Accurate diagnosis of these diseases is important during the fruit inspection process, particularly in the instance of fruit destined for export. Early near-harvest detection of latent infections in apple fruit is an important step to implement relevant pre- and postharvest measures for disease control. The aim of this study was to develop polymerase chain reaction (PCR) assays for diagnosis and early detection of latent infections of apple fruit by P. washingtonensis and S. pyriputrescens. Species-specific primers based on the rihosomal DNA internal transcribed spacer region were designed for use in PCR assays. Conventional and real-time PCR assays were developed and validated using fruit inoculated with P. washingtonensis, S. pyriputrescens, or B. cinerea and compared with identifications using traditional isolationbased assays. For wound-inoculated fruit, the PCR assays consistently provided the correct identification of the pathogen used as the inoculant in 6 h of processing time, compared with 5 to 6 days using culture-based methods. Real-time PCR assays effectively detected latent infections in symptomless stem and calyx tissues of fruit that were inoculated with the pathogens in the orchard during the growing season. The PCR assays provide a rapid, accurate method for diagnosis and early detection of these diseases.

For the resistant isolates that survived and sporulated in culture, colony expansion and conidial germination frequency was significantly reduced relative to the mean of 30 representative baseline isolates (EC sub(50) = 0.03 [mu]g/ml). Grape berries were inoculated with four isolates representing a range of knhexamid sensitivities and treated preventively or curatively with fenhexamid concentrations (150 to 600 mg/liter) representing 25 to 100% of the recommended rate. All treatments significantly delayed disease onset and progress caused by isolates with EC sub(50) values of 0.03 and 0.15 [mu]g/ml but provided little to no control of isolates with EC sub(50) values of 0.32 and 62.5 [mu]g/ml. The latter isolate exhibited a previously unreported F427V mutation of ERG27, an enzyme of ergosterol biosynthesis. In a duplex quantitative polymerase chain reaction test, the ratio of pathogen/host DNA increased significantly for 14 days after inoculation of untreated berries with a baseline isolate hut declined slightly in berries treated with fenhexamid at 600 mg/liter 1 day post inoculation. In the vineyard, disease control was affected by the number and rate of fenhexamid applications but B. cinerea isolates with EC sub(50) > or = 0.1 [mu]g/ml were not preferentially selected.

We isolated four chemicals from the trail of A. glabripennis virgin and mated females that were not present in trails of mature males. These compounds were identified as 2-methyldocosane and (Z)-9-tricosene (major components), as well as (Z)-9-pentacosene and (Z)-7-pentacosene (minor components); every trail wash sample contained all four chemical components, although the amounts and ratios changed with age of the female. Males responded to the full pheromone blend, regardless of mating status, but virgin females chose the control over the pheromone, suggesting that they may use it as a spacing pheromone to avoid intraspecific competition and maximize resources. Virgin, but not mated, males also chose the major pheromone components in the absence of the minor components, over the control. Taken together, these results indicate that all four chemicals are components of the trail pheromone. The timing of production of the ratios of the pheromone blend components that produced positive responses from males coincided with the timing of sexual maturation of the female.

Bees are thought to diminish its seed siring potential, but we found that foraging female generalist bees (Apis, Anthophora) deposited substantial amounts of conspecific pollen on P. eatonii stigmas. In the absence of hummingbirds, bee pollination of cultivated P. eatonii annually generated massive seed yields from a 1.5 ha field. Most penstemons with red tubular flowers like P. eatonii present a symmetrically flared floral opening that facilitates landing by foraging bees. Derived floral traits that attract and position nectar-foraging hummingbirds for efficient pollen export (red deeply tubular flowers secreting abundant dilute nectar) need not compromise pollination and seed production that result from visitation by generalist bees seeking pollen and/or nectar.

Realizing this potential will require technologies and management strategies that are tailored to the agroecosystems of the region, are economically viable, enhance the environment, and are sufficiently flexible to adapt to climate change. Forage production is the foundation for pasture-based dairy and livestock production, including low input and organic systems, and contributes to confined animal feeding operations through hay production. Pastures often include a diverse mixture ot numerous forage species, the identities of which depend on complex interactions between soil, climate, landscape, and management (Goslee and Sanderson 2010).

Furthermore, federal expenditures on agricultural conservation practices have received intense scrutiny in recent years. Simulation results indicated that cultivated cropland was the dominant source of nitrogen (N) and phosphorus (P) to both local waters and the Gulf, but this was not true for each water resource region within the MRB. In addition, the results showed that point sources remain significant contributors of P loads, especially in the Tennessee and Arkansas/Red River basins where point source P loads exceeded those from cultivated cropland. The results indicate the importance of targeted implementation of conservation practices and consideration of local water and/or Gulf impacts depending on program goal(s). The present application illustrates the value of the Cropland CEAP modeling framework as a useful, science-based tool to evaluate pollutant sources and delivery and effects of agricultural conservation practices.

The authors then discuss five observations about rural wealth creation, based on examples drawn from the recent literature on emerging energy industries in rural America. The cases show that the types of data needed to draw conclusions about wealth effects of new development are highly contextual. The framework can help researchers think about the types of data needed to assess policy.

Few studies have explored how interactions of biogeochemical transformations, various nitrogen sources, and catchment flow paths affect stream nitrogen variation during autumn. To provide more information on this critical period, we studied (1) the timing, duration, and magnitude of changes to stream nitrate, dissolved organic nitrogen (DON), and ammonium concentrations; (2) changes in nitrate sources and cycling; and (3) source areas of the landscape that most influence stream nitrogen. We collected samples at higher temporal resolution for a longer duration than typical studies of stream nitrogen during autumn. This sampling scheme encompassed the patterns and extremes that occurred during base flow and stormflow events of autumn. Base flow nitrate concentrations decreased by an order of magnitude from 5.4 to 0.7 mu mol L super(-1) during the week when most leaves fell from deciduous trees. Changes to rates of biogeochemical transformations during autumn base flow explained the low nitrate concentrations; in-stream transformations retained up to 72% of the nitrate that entered a stream reach. A decrease of in-stream nitrification coupled with heterotrophic nitrate cycling were primary factors in the seasonal nitrate decline. The period of low nitrate concentrations ended with a storm event in which stream nitrate concentrations increased by 25-fold. In the ensuing weeks, peak stormflow nitrate concentrations progressively decreased over closely spaced, yet similarly sized events. Most stormflow nitrate originated from nitrification in near-stream areas with occasional, large inputs of unprocessed atmospheric nitrate, which has rarely been reported for nonsnowmelt events. A maximum input of 33% unprocessed atmospheric nitrate to the stream occurred during one event. Large inputs of unprocessed atmospheric nitrate show direct and rapid effects on forest streams that may be widespread, although undocumented, throughout nitrogen-polluted temperate forests. In contrast to a week-long nitrate decline during peak autumn litterfall, base flow DON concentrations increased after leaf fall and remained high for 2 months. Dissolved organic nitrogen was hydrologically flushed to the stream from riparian soils during stormflow. In contrast to distinct seasonal changes in base flow nitrate and DON concentrations, ammonium concentrations were typically at or below the detection limit, similar to the rest of the year. Our findings reveal couplings among catchment flow paths, nutrient sources, and transformations that control seasonal extremes of stream nitrogen in forested landscapes. Key Points * Stream nitrate during autumn varied with inputs of atmospheric nitrate * Autumn leaf fall and stormflow events affected stream nitrate and DON dynamics * Stream nitrate and DON during autumn storms originated from riparian areas not hillslopes JF - Water Resources Research AU - Sebestyen, Stephen D AU - Shanley, James B AU - Boyer, Elizabeth W AU - Kendall, Carol AU - Doctor, Daniel H AD - USDA Forest Service, Northern Research Station, Grand Rapids, Minnesota, USA.

However, little is known about biochemical shifts in different potato genotypes in response to 'Ca. L. solanacearum' infection. To address this, 'Red La Soda', 'Russet Norkotah', and 'FL 1867' potato were infected with 'Ca. L. solanacearum' 4, 3, 2, and 1 weeks before harvest to observe variability in cultivar responses to 'Ca. L. solanacearum' infection. ZC symptoms, 'Ca. L. solanacearum' titers, and tuber biochemistry were assessed. Red La Soda tubers exhibited greatersymptoms when infected for 4 weeks than Russet Norkotah or FL 1867 tubers. 'Ca. L. solanacearum' titers did not vary among cultivars. Tuber levels of amino acids, carbohydrates, and phenolics varied among cultivars but no consistent trends were observed. Individual amino acids and phenolics were greater in FL 1867 than Red La Soda, whereas others were greater in Red La Soda or Russet Norkotah than FL 1867. Most amino acids, carbohydrates, and phenolics were positively associated with infection duration and symptoms regardless of cultivar. Associations between most of the evaluated compounds and 'Ca. L. solanacearum' titer were positive in Red La Soda. However, no associations between 'Ca. L. solanacearum' quantity and compounds were observed in FL 1867 and Russet Norkotah.

The types and frequencies of genetic resistance to the rust will likely determine the potential success of restoration or proactive measures. These first extensive inoculation trials using individual tree seed collections from >100 limber pine trees confirm that genetic segregation of a stem symptom-free trait to blister rust is consistent with inheritance by a single dominant resistance (R) gene, and the resistance allele appears to be distinct from the R allele in western white pine. Following previous conventions, we are naming the R gene for limber pine "Cr4." The frequency of the Cr4 allele across healthy and recently invaded populations in the Southern Rocky Mountains was unexpectedly high (5.0%, ranging from 0 to 13.9%). Cr4 is in equilibrium, suggesting that it is not a product of a recent mutation and may have other adaptive significance within the species, possibly related to other abiotic or biotic stress factors. The identification of Cr4 in native populations of limber pine early in the invasion progress in this region provides useful information for predicting near-term impacts and structuring long-term management strategies.

Viral coat proteins (CP) serve many functions in almost every aspect of the virus life cycle. The role of the C-terminal region of Wheat streak mosaic virus (WSMV) CP in virus biology was examined by mutating six negatively charged aspartic acid residues at positions 216, 289, 290, 326, 333, and 334. All of these amino acid residues are dispensable for virion assembly, and aspartic acid residues at positions 216, 333, and 334 are expendable for normal infection of wheat and maize. However, mutants D sub(289)N, D sub(289)A, D sub(290)A, DD sub(289/290)NA, and D sub(326)A exhibited slow cell-to-cell movement in wheat, which resulted in delayed onset of systemic infection, followed by a rapid recovery of genomic RNA accumulation and symptom development. Mutants D sub(289)N, D sub(289)A, and D sub(326)A inefficiently infected maize, eliciting milder symptoms, while D sub(290)A and DD sub(289/290)NA failed to infect systemically, suggesting that the C-terminus of CP is involved in differential infection of wheat and maize. Mutation of aspartic acid residues at amino acid positions 289, 290, and 326 severely debilitated virus ingress into the vascular system of maize but not wheat, suggesting that these amino acids facilitate expansion of WSMV host range through host-specific long-distance transport.

Soil nematodes were more abundant in burned and unburned juniper (Juniperus monosperma) tree patches than in yucca-shrub patches. There were no differences in nematode abundance between burned and unburned patches during the late spring and summer samples. Nematode abundance was significantly (p < 0.05) higher in unburned patches than in burned patches in the early spring samples, reflecting large differences in soil moisture between unburned and burned patches. There were no differences in soil nematode abundance between burned and unburned patches at oneyear post-burn and three-year post-burn sites. When all samples were pooled, taxonomic diversity, ecological indices, and abundance of trophic groups (bacteria-feeders, fungi-feeders, and omnivore-predators) were higher in unburned than burned patches. These results suggest that the long-term (up to three years post-burn) effects of fire on soil nematodes are indirect, i.e., by loss of tree canopies, litter accumulation, and shrub foliage, which affects soil temperatures and water redistribution.

Thus, field edges in these farmscapes include not only crop-to-crop interfaces but also those edges adjoining non-crop habitats. We examined the influence of field edges on colonization of stink bugs in southeastern USA farmscapes composed of typical combinations of corn, peanut, and cotton. For E. servus and N. viridula, egg-to-adult development and presence of both sexes on all crops indicated that the crops served as reproductive plants. Adult C. hilaris were rarely found on corn and on crops associated with it, and they were present mainly in cotton in peanut-cotton farmscapes. Mature crop height was significantly higher for corn than for cotton and significantly higher for cotton over peanut, and an edge effect in dispersal of stink bugs into a crop was detected up to 4.6, 8.2, and 14.6 m from the crop-to-crop interface in corn, cotton, and peanut, respectively. These results suggest that stink bug dispersal into a crop decreases as crop height increases. The first stink bug-infested crop at the crop-to-crop interface was the most significant contributor of colonizing stink bugs to an adjacent crop. An edge effect in dispersal of stink bug adults was detected in corn next to non-woodlands and woodlands and in cotton adjacent to woodlands. Edge effects were never detected in side edges of peanut. Overall, our results indicate that both plant height and host plant suitability can influence edge-mediated dispersal of stink bugs at field edges.

In a recent study, proteins from Pantoea ananatis and Serratia marcescens (Enterobacteriales: Enterobacteriaceae) were identified in diet that was stylet probed and fed on by L. hesperus adults. P. ananatis and S. marcescens are ubiquitous bacteria that infect a wide range of crops. The objective of our study was to determine whether L. hesperus transfer P. ananatis and S. marcescens to food substrates during stylet-probing activities. Sucrose (5%) was spread under parafilm and exposed to adult L. hesperus for 24 h. Diet similarly prepared but not exposed to insects was used for controls. MacConkey agar was inoculated with stylet-probed or control diets and incubated at 25 degree C. After 24 h, bacterial colonies were observed on agar that was inoculated with stylet-probed diet, but were not observed on agar inoculated with control diet. Isolated bacterial colonies were putatively identified as either Pantoea spp. or S. marcescens using the API 20e identification kit. These results indicate that L. hesperus is capable of vectoring P. ananatis and S. marcescens.

While the relative amount of sorbed As(V), Sb(III) and Pb(II) slightly decreased or remained unchanged, the sorption capacity of Zn(II) increased significantly with increasing amounts of immobilized humic acids in the Ca-alginate beads. Therefore, zinc is most likely preferentially sorbed to functional groups provided by humic acids rather than carboxyl or hydroxyl groups of alginate, with an optimum pH for uptake between 4 and 6. Nevertheless, the removal efficiency of metal(loid)s by unmodified Ca-alginate beads or those with humic acids modification was highest for Pb(II), at up to 93.5 %. The pH value also affects humic acids sorption properties on microbial surfaces. While the highest humic acids sorption capacity of mycelial pellets prepared from Aspergillus niger occurred at pH 8.5 (231 mg g super(-1)), the pelletized Aspergillus clavatus biomass was more effective in acidic solution and 199 mg g super(-1) was recorded there at pH 5.5. The effect of mutual interactions between humic acids and mycelial pellets on Zn(II) immobilization indicates that zinc affinity is higher for the fungal surface than for humic acids which do not supply sufficient active sorption sites for zinc. This resulted in less sorption capacity of the mycelial pellets modified with humic acids compared to the unmodified biomass.

Although the role of plant water stress on the population density and dispersal of H. vitripennis has been studied, nothing isknown about the effects of plant water stress on the transmission of chi . fastidiosa by H. vitripennis.Alaboratory study was conducted to determine the influence of plant water stress on the sharpshooter stylet probing behaviors associated with the acquisition and inoculation of chi . fastidiosa. Electrical penetration graph was used to monitor H. vitripennis feeding behaviors for 20-h periods on citrus [Citrus sinensis (L.) Osbeck] and almond [Prunus dulcis (Miller) D.A. Webb] plants subjected to levels of water stress. Adult H. vitripennis successfully located xylem vessels, then performed behaviors related to the evaluation of the xylem cell and fluid, and finally ingested xylem fluid from citrus and almond plants under the tested fluid tensions ranging from -5.5 to -33.0 bars and -6.0 to -24.5 bars, respectively. In general, long and frequent feeding events associated with the acquisition and inoculation of chi . fastidiosa were observed only in fully irrigated plants (i.e., >-10 bars), which suggests that even low levels of plant water stress may reduce the spread of chi . fastidiosa. Results provided insights to disease epidemiology and support the hypothesis that application of regulated deficit irrigation has the potential to reduce the incidence of diseases caused by chi . fastidiosa by reducing the number of vectors and by decreasing pathogen transmission efficiency.

However, despite this interplay, relatively little is known regarding IAV circulating in swine around the world compared with the avian and human knowledge base. This gap in knowledge impedes our understanding of how viruses adapted to swine or man impacts the ecology and evolution of IAV as a whole and the true impact of swine IAV on human health. The pandemic H1N1 that emerged in 2009 underscored the need for greater surveillance and sharing of data on IAV in swine. In this paper, we review the current state of IAV in swine around the world, highlight the collaboration between international organizations and a network of laboratories engaged in human and animal IAV surveillance and research, and emphasize the need to increase information in high-priority regions. The need for global integration and rapid sharing of data and resources to fight IAV in swine and other animal species is apparent, but this effort requires grassroots support from governments, practicing veterinarians and the swine industry and, ultimately, requires significant increases in funding and infrastructure.

Enzymes, such as hydrogenase which catalyze the reversible oxidation of molecular hydrogen, are known to mediate electron transfer to metals and may contribute to the formation and speciation of ferrous sulfides formed at the cell-mineral interface. In the present study, we compared the whole cell hydrogenase activity of Desulfovibrio desulfuricans strain Essex 6 growing as biofilms on hematite (hematite-associated) or as suspended populations using different metabolic pathways. Hematite-associated cells exhibited significantly greater hydrogenase activity than suspended populations during sulfate respiration but not during pyruvate fermentation. The enhanced activity of the hematite-associated, sulfate-grown cells appears to be dependent on iron availability rather than a general response to surface attachment since the activity of glass-associated cells did not differ from that of suspended populations. Hydrogenase activity of pyruvate-fermenting cells was stimulated by addition of iron as soluble Fe(II)Cl sub(2) and, in the absence of added iron, both sulfate-reducing and pyruvate-fermenting cells displayed similar rates of hydrogenase activity. These data suggest that iron exerts a stronger influence on whole cell hydrogenase activity than either metabolic pathway or mode of growth. The location of hydrogenase to the cell envelope and the enhanced activity at the hematite surface in sulfate-reducing cells may influence the redox conditions that control the species of iron sulfides on the mineral surface.

The disease causes yield loss and some fresh fruit trade restrictions may apply. Cultural management techniques such as windbreaks may work by not only reducing wind speed, but also reducing the period of exposure of susceptible foliage or fruit to those wind speeds that support infection from incoming inoculum. To investigate the effect of exposure period to inoculum of Xcc, seedlings of canker-susceptible Swingle citrumelo were exposed to sprayed inoculum for increasing periods at different wind speeds. The incidence and severity of citrus canker was assessed. In three experiments the incidence and severity of citrus canker most often increased with longer periods of exposure to inoculum, especially so at wind speeds of greater than or equal to 16 m/s compared to wind speeds of less than or equal to 5 m/s (wind speed also increased disease incidence and severity). Regression analysis demonstrated relationships between period of exposure to inoculum and the percent infected leaves per plant, the number of lesions per plant, the number of lesions per infected leaf, and for the percent of infected leaves with lesions on the petioles at wind speeds of greater than or equal to 16 m/s (R super(2)=0.16-0.72). Due to the effect of inoculum exposure period and wind speed, attempts should be made to minimize exposure of canker-susceptible citrus when wind speed is highest and inoculum is available. Windbreaks should help minimize periods of exposure to splashed inoculum in high winds.

Assessing and controlling phosphorus (P) inputs are, thus, considered the key to reducing eutrophication and managing ecological integrity. In this paper, we monitored and evaluated P concentrations of groundwater (GW) compared to the concentration of surface water (SW) P in forage-based landscape with managed cow-calf operations for 3 years (2007-2009). Groundwater samples were collected from three landscape locations along the slope gradient (GW1 10-30 % slope, GW2 5-10 % slope, and GW3 0-5 % slope). Surface water samples were collected from the seepage area (SW 0 % slope) located at the bottom of the landscape. Of the total P collected (averaged across year) in the landscape, 62.64 % was observed from the seepage area or SW compared with 37.36 % from GW (GW1=8.01 %; GW2=10.92 %; GW3=18.43 %). Phosphorus in GW ranged from 0.02 to 0.20 mg L super(-1) while P concentration in SW ranged from 0.25 to 0.71 mg L super(-1). The 3-year average of P in GW of 0.09 mg L super(-1) was lower than the recommended goal or the Florida's numeric nutrients standards (NNS) of 0.12 mg P L super(-1). The 3-year average of P concentration in SW of 0.45 mg L super(-1) was about fourfold higher than the Florida's NNS value. Results suggest that cow-calf operation in pasture-based landscape would contribute more P to SW than in the GW. The risk of GW contamination by P from animal agriculture production system is limited, while the solid forms of P subject to loss via soil erosion could be the major water quality risk from P.

Budburst for both species could be predicted by accumulating chilling and forcing units throughout the dormant season. Maximum predicted radial growth was comparable for pecan (2.19 mm) and white oak (2.26 mm), and peaked 28 days earlier for white oak (3 June) than pecan (1 July). White oak LAI generally exceeded that of pecan during the growing season. Senescence began about 27 October regardless of species, and was better characterized by decreasing Fv/Fm or total chlorophyll concentration than LAI. Phenology was generally not responsive to N fertilization, perhaps because of adequate soil and foliar N. The study provides additional information on growth responses of these high-valued species to supplemental fertilization on an upland site.

Winter recreation could be benign, however, if animals habituate. Moreover, recreation creates trails. Traveling on them could reduce energy expenditure, thereby increasing ungulate survivorship and generating population benefits. Balancing recreation use with wildlife stewardship requires identifying when these effects occur. This task would be simpler if guidelines existed to inform assessments. We developed and tested such guidelines using two approaches. First, we synthesized literature describing the effects of winter recreation-motorized and nonmotorized-on northern ungulates. This synthesis enabled formulating six guidelines, while exposing two requiring further attention (ungulate habituation and displacement). Second, we tested these two guidelines and evaluated the others by quantifying the behavioral responses of moose to snowmobiles, in two areas of south-central Alaska, differing by snowmobile predictability. For each location, we modeled moose preferences during the snowmobile period using different combinations of eight variables-static (elevation and slope), biotic (habitat and cover), and anthropogenic (distance to roads, railroads, snowmobile trails, and trail density). We identified the model with the most support and used it to estimate parameter coefficients for pre- and post-recreation periods. Changes in coefficients between periods indicated snowmobile effects on moose. Overall, we produced and evaluated six guidelines describing when winter recreation is potentially detrimental to ungulates as follows: (1) when unpredictable, (2) spanning large areas, (3) long in duration, (4) large spatial footprint, (5) nonmotorized, and (6) when animals are displaced to poor quality habitats.

Large trash (e.g., televisions, toilets, car parts) dumped in streams provided shelter for some aquatic fauna. To determine whether trash served as a surrogate for natural cover, I examined crayfish use of both cover types. I sampled crayfishes by kick-seining 2 1-m plots in three cover classes: trash, natural cover, and no cover. I captured 415 crayfishes from 136 of the 294 plots. Most crayfishes were in natural cover (253), followed by trash (154), and no-cover (8) plots. Trash use varied by crayfish genus and size. Frequencies of all size classes of Procambarus and of the smallest Cambarus were higher in natural cover than trash. Many of the smallest individuals were found in live root mats. As Cambarus and Orconectes grew, they shifted more toward trash, and the largest Orconectes size class was significantly more abundant than expected in trash. Trash served as "artificial reefs," providing cover for crayfishes and other fauna, but functioned differently than the remaining natural cover. The results confirmed that stream substrate did not provide adequate instream cover for crayfishes in the study area and suggested that high-quality natural cover for large crayfishes was in short supply, at least for some species. Land management that provides for abundant, ongoing input and retention of complex cover, such as trees and live roots, to stream channels should be beneficial for crayfish assemblages.

However, few studies have quantified the strength and timing of herbivore selection for burned areas or examined how selection strength varies among ecosystems differing in precipitation and primary productivity.We conducted a 4-year patch-burning experiment in semi-arid rangeland of Colorado, USA, where 25% of the area available to cattle was burned each year and burned patches were shifted annually. We used GPS collars with activity sensors to quantify the distribution of free-ranging cattle at a high temporal resolution (5-min intervals) during the growing season each year. We used a classification tree model to discriminate between cattle grazing vs. non-grazing locations, which significantly increased precision in quantifying burn selection strength. We fit generalized linear models predicting the frequency of cattle use of a given location within each study area and month, enabling comparisons between the relative influence of burns and topography on grazing distribution.Across multiple growing seasons, cattle selectively spent 31% of grazing time on recently burnt areas, which comprised 25% of the landscape; this selection strength was half as strong as that documented in mesic rangeland.At a monthly temporal scale, strong cattle selection for burned areas occurred during periods of rapid vegetation growth regardless of when during the growing season this greening occurred. Outside these intervals, burn selection strength was inconsistent and cattle grazing distribution was primarily influenced by topography. Thus, the relative importance of fire and topography in controlling grazer distribution was temporally contingent upon the timing and size of precipitation pulses.Synthesis and applications. Spatiotemporal interactions between fire and herbivores are a consistent feature of both semi-arid and mesic rangelands, with interaction strength varying across gradients of precipitation and primary productivity. Management of semi-arid ecosystems to sustain ecological processes should include strategies that allow ungulate herbivores to shift their grazing distribution seasonally in response to fire, topoedaphic variation and precipitation patterns. Combined management of fire and grazing for conservation objectives can be consistent with, and even complementary to, livestock production goals.

Changes in the definition of forest intended to improve international consistency can affect the ability to quantify true changes over time. The objective of this study was to evaluate the effects of a definitional change from relative stocking to canopy cover on the area classified as forest land and its relationship to species and forest density in California, Oregon, and Washington. Both western Juniper and ponderosa pine will yield higher estimates of forest land area using a canopy cover definition in comparison to a stocking-based definition, with the difference being most pronounced where land is marginally forested. The change in definition may result in an additional 146,000 ha of forest land identified on the West Coast. Measuring marginal forest lands with both metrics for the first cycle after implementation should make it possible to distinguish real change from definitional change.

Heifers were separated into treatment groups receiving either a Control diet, YCW-A or YCW-C, and were fed for 52d. Heifers were weighed on d 0, 14, 36, 38 and 52. On d 37 heifers were challenged i.v. with LPS [0.5 mu g/kg body weight (BW)] and blood samples were collected relative to LPS challenge. Heifer BW increased from d 0 to 36 and from d 38 to 52, but was not affected by treatment. Post-LPS, glucose concentrations increased and were less in YCW-A than Control and YCW-C heifers. Pre-LPS, insulin concentrations were greater in YCW-A and YCW-C than Control heifers. Post-LPS, insulin concentrations increased with YCW-C having greater insulin than Control heifers. Pre-LPS, NEFA concentrations tended to be less in YCW-C than Control heifers. Post-LPS non-esterified fatty acids (NEFA) concentrations were less in YCW-C than Control and YCW-A heifers. Post-LPS, blood urea nitrogen (BUN) concentrations were greater in YCW-A than Control and YCW-C. These data indicate, based on NEFA and BUN data, that certain YCW products can enhance energy metabolism during an immune challenge without causing lipolysis or muscle catabolism.

AN - 1492638706; 18996958 AB - The lady beetle Coleomegilla maculata De Geer is an omnivorous predator that could help suppress aphid and spider mite populations on plants in greenhouses, plantscapes or interiorscapes. We are assessing the nutritional requirements and feeding behavior of C. maculata on target prey (spider mites) and factitious (unnatural) food. Our ultimate goal is to develop an efficacious diet to mass produce C. maculata. In this study, we tested the hypothesis that Tetranychus urticae Koch (two-spotted spider mite) is not suitable prey for development and reproduction of naive C. maculata (i.e., with no prior exposure to T. urticae). Our objectives were to (i) provide baseline data on the effects of consuming T. urticae on C. maculata life history, (ii) to compare the effects of consuming all stages of T. urticae versus eggs of Musca domestica L. (common housefly), and (iii) to determine if the consumption of plant products was beneficial. We used C. maculata from a colony reared only on Ephestia kuehniella Zeller (Mediterranean flour moth) eggs. In experiments, C. maculata larvae were reared from the first instar to adult stage with prey/food in replicated arenas; adult females were paired with a single male with prey/food. The results showed that naive C. maculata readily attacked and consumed T. urticae. Nevertheless, T. urticae was less suitable than M. domestica eggs for C. maculata development and reproduction.

AN - 1490778160; 24316068 AB - Improved approaches are needed to assess bioavailability of hydrophobic organic compounds in contaminated soils. Performance of thin-film solid-phase extraction (TF-SPE) using vials coated with ethylene vinyl acetate was compared to earthworm bioassay (Lumbricus terrestris). A DDT and dieldrin contaminated soil was amended with four organic carbon materials to assess the change in bioavailability. Addition of organic carbon significantly lowered bioavailability for all compounds except for 4,4'-DDT. Equilibrium concentrations of compounds in the polymer were correlated with uptake by earthworms after 48d exposure (R(2) = 0.97; p 40yr of aging. Results show that TF-SPE can be useful in examining potential risks associated with contaminated soils and to test effectiveness of remediation efforts. Published by Elsevier Ltd.

AN - 1490759807; 24401405 AB - Due to high toxicity, inorganic arsenic (iAs) species are the focus of monitoring effort worldwide. In this work arsenic was first extracted from rice by microwave-assisted digestion in HNO3-H2O2, during which As(III) was oxidized to As(V). Silica-based strong anion exchange cartridges were used to separate As(V) from organic forms. After prereduction by iodide, iAs was quantified by hydride-generation atomic fluorescence spectrometry (HG-AFS). This method achieved 1.3 ng g(-1) limit of detection (LOD), and 94 ± 3% and 93 ± 5% recoveries, respectively, for As(III) and As(V) at 100 ng g(-1). Validation was performed using standard reference material NIST 1568a (102 ng g(-1)) and ERM BC211 (124 ng g(-1)) rice flour. By eliminating chromatography, SPE speciation gained throughput and cost advantages. HG-AFS, at 10% budget and operation cost of a typical inductively-couple plasma mass spectrometer (ICPMS), proved highly sensitive and specific for iAs quantification. Published by Elsevier B.V.

AN - 1492686527; 24464236 AB - The majority of modern war wounds are characterized by high-energy blast injuries containing a wide range of retained foreign materials of a metallic or composite nature. Health effects of retained fragments range from local or systemic toxicities to foreign body reactions or malignancies, and dependent on the chemical composition and corrosiveness of the fragments in vivo. Information obtained by chemical analysis of excised fragments can be used to guide clinical decisions regarding the need for fragment removal, to develop therapeutic interventions, and to better anticipate future medical problems from retained fragment related injuries. In response to this need, a new U.S Department of Defense (DoD) directive has been issued requiring characterization of all removed fragments to provide a database of fragment types occurring in combat injuries. The objective of this study is to determine the chemical composition of retained embedded fragments removed from injured military personnel, and to relate results to histological findings in tissue adjacent to fragment material. We describe an approach for the chemical analysis and characterization of retained fragments and adjacent tissues, and include case examples describing fragments containing depleted uranium (DU), tungsten (W), lead (Pb), and non-metal foreign bodies composed of natural and composite materials. Fragments obtained from four patients with penetrating blast wounds to the limbs were studied employing a wide range of chemical and microscopy techniques. Available adjacent tissues from three of the cases were histologically, microscopically, and chemically examined. The physical and compositional properties of the removed foreign material surfaces were examined with energy dispersive x-ray fluorescence spectrometry (EDXRF), scanning electron microscopy (SEM), laser ablation inductively-coupled plasma mass-spectrometry (LA-ICP-MS), and confocal laser Raman microspectroscopy (CLRM). Quantitative chemical analysis of both fragments and available tissues was conducted employing ICP-MS. Over 800 fragments have been characterized and included as part of the Joint Pathology Center Embedded Fragment Registry. Most fragments were obtained from penetrating wounds sustained to the extremities, particularly soft tissue injuries. The majority of the fragments were primarily composed of a single metal such as iron, copper, or aluminum with traces of antimony, titanium, uranium, and lead. One case demonstrated tungsten in both the fragment and the connected tissue, together with lead. Capsular tissue and fragments from a case from the 1991 Kuwait conflict showed evidence of uranium that was further characterized by uranium isotopic ratios analysis to contain depleted uranium. The present study provides a systematic approach for obtaining a full chemical characterization of retained embedded fragments. Given the vast number of combat casualties with retained fragments, it is expected that fragment analysis will have significant implications for the optimal short and long-term care of wounded service members.

AN - 1467070064; 24055666 AB - The atmosphere is an important transport route for semi-volatile pesticides like endosulfan. Deposition, which depends on physical-chemical properties, use patterns, and climatic conditions, can occur at local, regional, and global scales. Adverse human and ecological impact may result. We measured endosulfan wet deposition in precipitation over a 4-year period within an area of high agricultural use in Southern Florida (USA) and in nearby Biscayne and Everglades National Parks. Endosulfan's two isomers and degradate, endosulfan sulfate, were detected at high frequency with the order of detection and concentration being β-endosulfan>α-endosulfan>endosulfan sulfate. Within the agricultural area, detection frequency (55 to 98%) mean concentrations (5 to 87 ng L(-1)) and total daily deposition (200 ng m(-2) day(-1)) exceeded values at other sites by 5 to 30-fold. Strong seasonal trends were also observed with values at all monitored sites significantly higher during peak endosulfan use periods when vegetable crops were produced. Relatively high deposition in the crop production area and observations that concentrations exceeded aquatic life toxicity thresholds at all sites indicated that endosulfan volatilization and wet deposition are of ecotoxicological concern to the region. This study emphasizes the need to include localized volatilization and deposition of endosulfan and other semi-volatile pesticides in risk assessments in Southern Florida and other areas with similar climatic and crop production profiles. © 2013.

Increased peak flows and sediment delivery due to the loss of surface cover and fire-induced changes in soil properties are of great concern to both resource managers and the public. To respond to this threat, interdisciplinary Burned Area Emergency Response (BAER) Teams are formed to assess potential erosion and flood risks. These teams are under tight deadlines as remediation plans and treatments must be developed and implemented before the first major storms in order to be effective. One of the primary sources of information for making these decisions is a burn severity map derived from remote sensing data (typically Landsat) that reflects fire induced changes in vegetative cover and soil properties. Slope, soils, land cover, and climate are also important parameters that need to be considered when accessing risk. Many modeling tools and datasets have been developed to assist BAER teams, but process-based and spatially explicit empirical models are currently under-utilized compared to simpler, lumped models because they are both more difficult to set up and require spatially explicit inputs such as digital elevation models, soils, and land cover. We are working to facilitate the use of models by preparing spatial datasets within a web-based tool that rapidly modifies model inputs using burn severity maps derived from earth observation data. Automating the creation of model inputs facilitates the wider use of more accurate, process-based models for spatially explicit predictions of post-fire erosion and runoff.

The HPLC-DAD-MS/MS profiles of red onion, Chinese lettuce, carrot leaf, and celery seed extracts were analyzed by the proposed computer-aided screening method for identifying possible flavone/flavonol glycoside peaks from the HPLC-UV and MS total ion current (TIC) chromatograms. The number of identified flavone/flavonol glycoside peaks of the HPLC-UV chromatograms is four, four, six, and nine for red onion, Chinese lettuce, carrot leaf, and celery seed, respectively. These results have been validated by human experts. For the batch processing of nine HPLC-DAD-MS/MS profiles of celery seed extract, the entire script execution time was within 15 s while manual calculation of only one HPLC-DAD-MS/MS profile by a flavonoid expert could take hours. Therefore, this MATLAB-based screening method is able to facilitate the HPLC-DAD-MS/MS analysis of flavone/flavonol glycosides in plants to a large extent.

The Root Zone Water Quality Model (RZWQM) has been tested under a variety of conditions. However, the current model's ability to simulate pesticide transport to subsurface drain flow over a long term period under different tillage systems and application rates is not clear. Therefore, we calibrated and tested RZWQM using six years of data from Nashua, Iowa. In this experiment, atrazine was spring applied at 2.8 (1990-1992) and 0.6kg/ha/yr (1993-1995) to two 0.4ha plots with different tillage (till and no-till). The observed and simulated average annual flow weighted atrazine concentrations (FWAC) in subsurface drain flow from the no-till plot were 3.7 and 3.2 mu g/L, respectively for the period with high atrazine application rates, and 0.8 and 0.9 mu g/L, respectively for the period with low application rates. The 1990-1992 observed average annual FWAC difference between the no-till and tilled plot was 2.4 mu g/L while the simulated difference was 2.1 mu g/L. These observed and simulated differences for 1993-1995 were 0.1 and 0.1 mu g/L, respectively. The Nash-Sutcliffe model performance statistic (EF) for cumulative atrazine flux to subsurface drain flow was 0.93 for the no-till plot testing years (1993-1995), which is comparable to other recent model tests. The value of EF is 1.0 when simulated data perfectly match observed data. The order of selected parameter sensitivity for RZWQM simulated FWAC was atrazine partition coefficient>number of macropores>atrazine half life in soil>soil hydraulic conductivity. Simulations from 1990 to 1995 with four different atrazine application rates applied at a constant rate throughout the simulation period showed concentrations in drain flow for the no-till plot to be twice those of the tilled plot. The differences were more pronounced in the early simulation period (1990-1992), partly because of the characteristics of macropore flow during large storms. The results suggest that RZWQM is a promising tool to study pesticide transport to subsurface drain flow under different tillage systems and application rates over several years, the concentrations of atrazine in drain flow can be higher with no-till than tilled soil over a range of atrazine application rates, and atrazine concentrations in drain flow are sensitive to the macropore flow characteristics under different tillage systems and rainfall timing and intensity.

Here, we present a long-term (1936-2005) yearling Hereford steer dataset collected at the Northern Great Plains Research Laboratory (NPGRL) near Mandan, ND, USA. Data were analyzed using weighted AICc model averaging to examine the effects of spring (April-June) and summer (July-September) temperature and precipitation, as well as prior growing season (prior April-September) and prior fall/winter (prior October-March) precipitation on cattle production (kg/ha) under light (37.4 plus or minus 5.3SD Animal Unit Days [AUD]/ha across all study years) and heavy (91.6 plus or minus 22.2SD AUD/ha) stocking rates. Because Kentucky bluegrass (Poa pratensis L.) invaded the grassland at NPGRL in the early 1980s, we modeled cattle production separately for pre- (1936-1983) and post-invasion (1986-2005) years to determine if the plant community shift influenced sensitivity to seasonal weather patterns. Cattle production under heavy stocking was more sensitive to seasonal weather variability than under light stocking during both pre- and post-invasion years. Interestingly, the magnitude and robustness of coefficients changed between the pre- and post-invasion years, with seasonal weather patterns explaining more cattle production variation during the post-invasion years. Though cattle sensitivity to seasonal weather patterns differed between light and heavy stocking for both pre- and post-invasion years, invasion status did change cattle response to weather. For example, cattle production in P. pratensis invaded pastures was more heavily influenced by cool, wet springs and wet prior grazing seasons than was production in un-invaded pastures. For cattle stocked heavily in native pastures, wet winters more strongly increased cattle production than in invaded pastures.

Here, we explore how heterogeneity, feedbacks, and external drivers in this type of natural hazard system can lead to complexity and can limit the development of more adaptive approaches to policy and management. Institutions and social networks can counter these limitations and promote adaptation. We also develop a conceptual model that includes a robust characterization of social subsystems for a fire-prone landscape in Oregon and describe how we are building an agent-based model to promote understanding of this social-ecological system. Our agent-based model, which incorporates existing ecological models of vegetation and fire and is based on empirical studies of landowner decision-making, will be used to explore alternative management and fire scenarios with land managers and various public entities. We expect that the development of CHANS frameworks and the application of a simulation model in a collaborative setting will facilitate the development of more effective policies and practices for fire-prone landscapes.

In various cities worldwide, novel ideas, initiatives, and networks are emerging in governance to address social and ecological conditions in urban areas. However, cities can be contested spaces, bringing a plurality of actors, network configurations, preferences, and knowledge that shape the politics over desirable pathways for future development. I used the knowledge-action systems analysis (KASA) approach to examine the frames and knowledge systems influencing how different actors involved in the land governance network of the city of San Juan constructed visions for the future of the city. Results revealed four visions for the city coexisting in San Juan. Although sustainability is a goal that cuts across all four visions, they each optimized distinct dimensions of the concept. The contrasts in visions can be explained in part by competing frames of the urban social-ecological system and power asymmetries in the multiple knowledge systems coexisting in the city. I discussed the theoretical, methodological, and practical implications of the politics of sustainability for adaptive urban governance research and practice. The KASA approach can serve as a window into the adaptive capacity of the city by disentangling the competing ways that actors 'see' and 'know' the urban social-ecological systems. Most importantly, this approach offers a way of appraising sustainable pathways by revealing either the extent to which dominant social structures and cognitive patterns are being reinforced, or whether opportunities for innovative and transformative approaches are emerging in the city.

Based on data from a series of semi-structured elite interviews with bureaucrats working at the Norwegian Ministry of Defence (MOD) and the Ministry of Foreign Affairs (MFA), this article presents an inside-out analysis focused on bureaucrats and policymaking. The relationships between bureaucrats and politicians within the MOD and between bureaucrats in the MOD and the MFA are explored. It is found that bureaucrats at the MOD were particularly active in the process of drafting the initiative. The analysis also draws attention to what seem to be conflicting interests within the bureaucracy in promoting the Core Area Initiative. Adapted from the source document.

A variety of additives with presumed anti-microbial and/or growth-promoting effects are commonly added to poultry feed during commercial grow-out, yet the effects of these additives on the gastrointestinal microbial community (the GI microbiome) as the bird matures remain largely unknown. Here we compared temporal changes in the cecal microbiome to the effects of formic acid, propionic acid, and medium-chain fatty acids (MCFA) added to feed and/or drinking water. Results: Cecal bacterial communities at day of hatch (n = 5 birds), 7d (n = 32), 21d (n = 27), and 42d (n = 36) post-hatch were surveyed using direct 454 sequencing of 16S rRNA gene amplicons from each bird in combination with cultivation-based recovery of a Salmonella Typhimurium marker strain and quantitative-PCR targeting Clostridium perfringens. Treatment effects on specific pathogens were generally non-significant. S. Typhimurium introduced by oral gavage at day of hatch was recovered by cultivation from nearly all birds sampled across treatments at 7d and 21d, but by 42d, S. Typhimurium was only recovered from ca. 25% of birds, regardless of treatment. Sequencing data also revealed non-significant treatment effects on genera containing known pathogens and on the cecal microbiome as a whole. In contrast, temporal changes in the cecal microbiome were dramatic, highly significant, and consistent across treatments. At 7d, the cecal community was dominated by three genera (Flavonifractor, Pseudoflavonifractor, and a Lachnospiracea sequence type) that accounted for more than half of sequences. By 21d post-hatch, a single genus (Faecalibacterium) accounted for 23-55% of sequences, and the number of Clostridium 16S rRNA gene copies detected by quantitative-PCR reached a maximum. Conclusions: Over the 42 d experiment, the cecal bacterial community changed significantly as measured by a variety of ecological metrics and increases in the complexity of co-occurrence networks. Management of poultry to improve animal health, nutrition, or food safety may need to consider the interactive effects of any treatments with the dramatic temporal shifts in the taxonomic composition of the cecal microbiome as described here.

Here, I provide a high spatial resolution snapshot of the green cover distribution of the city of San Juan, Puerto Rico, by incorporating the use of morphological spatial pattern analysis (MSPA) as a tool to describe the spatial pattern and connectivity of the city's urban green areas. Analysis of a previously developed IKONOS 4-m spatial resolution classification of the city of San Juan from 2002 revealed a larger area of vegetation (green areas or green infrastructure) than previously estimated by moderate spatial resolution imagery. This study explores the intra-urban vegetation variation in the city of San Juan, which is generally overlooked by moderate spatial resolution classifications in Puerto Rico. The effectiveness of research and city planning will be further enhanced as a result of this type of finer-scale urban cover exploration.

Recent methodological advances have spurred the recognition of microbiomes as complex communities with important influences on the health and disease status of the host. In this minireview, we provide an overview of the current state of knowledge of the chicken gastrointestinal microbiome focusing on spatial and temporal variability, the presence and importance of human pathogens, the influence of the microbiota on the immune system, and the importance of the microbiome for poultry nutrition. Review and meta-analysis of public data showed cecal communities dominated by Firmicutes and Bacteroides at the phylum level, while at finer levels of taxonomic resolution, a phylogenetically diverse assemblage of microorganisms appears to have similar metabolic functions that provide important benefits to the host as inferred from metagenomic data. This observation of functional redundancy may have important implications for management of the microbiome. We foresee advances in strategies to improve gut health in commercial operations through management of the intestinal microbiota as an alternative to in-feed subtherapeutic antibiotics, improvements in pre- and probiotics, improved management of polymicrobial poultry diseases, and better control of human pathogens via colonization reduction or competitive exclusion strategies. In this mini-review, we provide an overview of the current state of knowledge of the chicken gastrointestinal microbiome focusing on spatial and temporal variability, the presence and importance of human pathogens, the influence of the microbiota on the immune system, and the importance of the microbiome for poultry nutrition.

First, the city is subject to multiple vulnerabilities, but socioeconomic factors and education level affect the perception of citizens to those vulnerabilities, even in the face of imminent threat. Second, in light of the social-ecological conditions of the city, how its citizens and institutions deal with knowledge to respond to vulnerabilities becomes critical to the adaptive capacity of the city. Third, the relationship between socioeconomic factors and green cover, which in 2002 covered 42% of the city, is not what has been reported for other temperate zone cities. Fourth, tropical conditions such as climate may explain some of the unique aspects of the social-ecological system of San Juan. We conclude that the study of a tropical city provides contrast to the prevailing literature on temperate and boreal cities and expands the suite of behaviors of urban social-ecological systems, thus advancing the dialogue on the functioning of cities in light of environmental change.

Recently harvested timber stumps were mechanically inspected for the presence of subterranean termites in multiple locations across southern Mississippi and eastern Louisiana. A systematic line plot cruise with 100 x 200m spacing and 1/20th ha plots was implemented, and all stumps with a diameter greater than 7.6cm were inspected. In total, 7,413 stumps were inspected for the presence of subterranean termites, and 406 of those contained native subterranean termites (Reticulitermes spp.). Light traps were also placed at 8 sites to detect the presence of subterranean termite alates. While no invasive Formosan subterranean termites were found during mechanical inspection of tree stumps, alates were captured in light traps at three sites. The proportion of stumps infested with subterranean termites was negatively correlated with the number of stumps in each plot. Although 6.27% of pine stumps and 1.86% of hardwood stumps contained subterranean termites, no correlation was found between subterranean termite presence and type of stump (pine or hardwood) inspected. Subterranean termite presence in stumps ranged from 0.94% to 14.97% depending on site.

Previous studies focused on invasive fishes have revealed that these species have the capability to generate forms with life-history traits that differ between native and non-native populations. As a contribution to explain their invasion success, the theory of alternative ontogenies and invasive potential has been developed. The main aim of the present study was to test the hypothesis derived from this theory, which predicts that females of the non-native population of N. melanostomus (from Slovakia) will have significantly smaller oocytes, higher fecundity and smaller body size at maturity than those of the native population (from Bulgaria). All the three quantitative parameters of life-history traits examined in this study were found to be consistent with the predictions tested. Variations in reproductive parameters observed in non-native N. melanostomus demonstrate the species' phenotypic plasticity, which appears to be an important attribute that helps potential invaders to establish new populations in unknown environments. However, further experimental studies are necessary to verify this theory by testing hypotheses derived from it.Original Abstract: Une des especes les plus envahissantes de poissons aux impacts negatifs est le gobie a taches noires Neogobius melanostomus qui s'est propage a partir de sa zone ponto-caspienne native vers l'ouest et le centre de l'Europe et meme en Amerique du Nord. Des etudes anterieures sur les poissons invasifs ont revele que ces especes ont la capacite de generer des individus avec des traits d'histoire de vie qui different entre les populations autochtones et non autochtones. En guise de contribution a expliquer leur succes d'invasion, la theorie des ontogeneses alternatives et du potentiel invasif a ete developpee. L'objectif principal de cette etude etait de tester l'hypothese derivee de cette theorie, qui predit que les femelles de la population non autochtone de N. melanostomus (de Slovaquie) auront de plus petits ovocytes, une plus forte fecondite et une plus petite taille a maturite que celles de la population autochtone (de Bulgarie). Tous les trois parametres quantitatifs des traits d'histoire de vie examines dans cette etude ont ete juges conformes aux predictions testees. Les variations dans les parametres de reproduction observes chez N. melanostomus non indigenes demontrent la plasticite phenotypique de l'espece, qui semble etre un attribut important qui aide les envahisseurs potentiels a etablir de nouvelles populations dans des environnements inconnus. Toutefois, d'autres etudes experimentales sont necessaires pour verifier cette theorie en testant des hypotheses qui en decoulent.

Among youth, teenagers (teens) achieve the lowest levels of physical activity, and high school age youth are particularly at risk of inactivity. Effective methods are needed to increase youth physical activity in a way that can be maintained through adulthood. Because teens text a great deal, text messages promoting walking, a low cost physical activity, may be an effective method for promoting sustainable physical activity. The objective of our study was to determine the effect of pedometers, self selected step goals, and texts grounded in the self-determination theory (SDT) on physical activity among the teens. To our knowledge, this is one of the first studies to explore the use of stand alone, SDT grounded texts, supported by pedometers and prompts to set a self selected step goal, as a method for increasing physical activity among teens. This pilot study will contribute valuable information regarding whether theoretically grounded text messages show promise as an effective method to increase physical activity among teens.

Results: In this work we have tested a dozen commercial bacterial genomic DNA extraction methodologies on an average of 7.70 x 10 super(6) ( plus or minus 9.05%), 4.77 x 10 super(8) ( plus or minus 31.0%), and 5.93 x 10 super(8) ( plus or minus 4.69%) colony forming units (CFU) associated with 3 cultures (n = 3) each of Brochothrix thermosphacta (Bt; Gram-positive), Shigella sonnei (Ss; Gram-negative), and Escherichia coli O79 (Ec; Gram-negative). We have utilized real-time PCR (qPCR) quantification with two specific sets of primers associated with the 16S rRNA "gene" to determine the number of copies CFU super(-1) by comparing the unknown target DNA qPCR results with standards for each primer set. Based upon statistical analyses of our results, we determined that the Agencourt Genfind v2, High Pure PCR Template Prep Kit, and Omnilyse methods consistently provided the best yield of genomic DNA ranging from 141 to 934, 8 to 21, and 16 to 27 16S rDNA copies CFU super(-1) for Bt, Ss, and Ec. If one assumes 6-7 copies of the 16S rRNA gene per genome, between 1 and 3 genomes per actively dividing cell and greater than or equal to 100 cells CFU super(-1) for Bt (found to be a reasonable assumption using an optical method expounded upon herein) or between 1 and 2 cells CFU super(-1) for either Ss or Ec, then the Omnilyse procedure provided nearly quantitative extraction of genomic DNA from these isolates (934 plus or minus 19.9 copies CFU super(-1) for Bt; 20.8 plus or minus 2.68 copies CFU super(-1) for Ss; 26.9 plus or minus 3.39 copies CFU super(-1) for Ec). The Agencourt, High Pure, and Omnilyse technologies were subsequently assessed using 5 additional Gram-positive and 10 Gram-negative foodborne isolates (n = 3) using a set of "universal" 16S rDNA primers. Conclusion: Overall, the most notable DNA extraction method was found to be the Omnilyse procedure which is a "bead blender" technology involving high frequency agitation in the presence of zirconium silicate beads.

In the first experiment, we determined whether columnaris disease could be developed by experimental challenge in HSB. This challenge consisted of 3 levels of F. columnare (10, 30, and 60 ml volumes) determined to be 2.25 x 10 super(7), 6.75 x 10 super(7), and 1.35 x 10 super(8) CFU ml super(-1), respectively. Each treatment group exhibited significantly different survival rates: 0, 3.3, and 13.3% in the 60, 30, and 10 ml groups, respectively. In Expt 2, using the 30 ml dose, both HSB and WB had a 0% survival rate, with WB taking significantly longer to reach 100% mortality. In Expt 3, using the 10 ml dose, no HSB survived, whereas 33% of WB survived (p < 0.0001). Compared to controls, HSB treated with 10 ml showed extensive gill damage at 24 h, which could have contributed to the higher mortality observed in HSB; in contrast, WB gills showed noticeably less damage. From these series of experiments, it is clear that HSB are more sensitive to F. columnare, having lower survival and more extensive histological damage compared to WB following challenge.

For land managers working to support biotic resiliency in these systems, an understanding of these interactions is critical for effective stewardship. Here we report on plant-soil interactions at the American Prairie Reserve in north-central Montana, where the transition from cattle to bison management raises questions about controls on plant community distribution. In this region, as aridity and salinity become limiting, grasslands give way to sagebrush steppe communities, reflecting a transition to strong control of plant community distribution by the interaction of geomorphic drivers with soil development. This threshold in plant-soil interaction marks both decreased rainfall and the exposure of clay-rich, saline marine sedimentary rocks following advance and retreat of the continental ice sheet 12-20 ka. Soils in this area are primarily characterized by limited redistribution of salts, both downward within profiles and as a function of microtopographic variation and surface stability. Five primary vegetation associations with distinct plant species composition in the core of the APR are closely tied to geomorphic position and soil character. Our results indicate that the development of sagebrush steppe and reduction of soil salinity is an outcome that reflects long-term surface stability over the last approximately 9,000 years. A positive feedback results from establishment of prairie clubmoss and diverse herbaceous plant species in sagebrush interspaces, enhancing surface soil stability and increasing surface soil organic carbon content. Geochemical comparison of parent shales with soils reveals how salinity patterns and plant communities emerge as a function of time and surface disturbance, accounting for both natural processes of erosion and human activity. These interactions in turn drive water redistribution and grazer response, as well as human choices about land management.

However, the magnitude and value of the effects of trees and forests on air quality and human health across the United States remains unknown. Computer simulations with local environmental data reveal that trees and forests in the conterminous United States removed 17.4 million tonnes (t) of air pollution in 2010 (range: 9.0-23.2 million t), with human health effects valued at 6.8 billion U.S. dollars (range: $1.5-13.0 billion). This pollution removal equated to an average air quality improvement of less than one percent. Most of the pollution removal occurred in rural areas, while most of the health impacts and values were within urban areas. Health impacts included the avoidance of more than 850 incidences of human mortality and 670,000 incidences of acute respiratory symptoms.

AN - 1639992536; 20465617 AB - Solanum aethiopicum L. is native to sub-Saharan Africa but is now found in many parts of the world. It is used for food, medicinal, and ornamental purposes. It has also been used as a rootstock for tomato and common eggplant because of its resistance to certain pathogens. However, very little is known about its genetics, so the purpose of this work was to assess intraspecific variability in S. aethiopicum via morphological and cytomolecular characterization of 12 scarlet eggplant accessions. Cluster analysis was used for grouping the accessions using means of 27 variables. Four separate groups were found, with two groups each consisting of five accessions and two other groups each consisting of only one accession. Variability was high with flower- and fruit-associated descriptors among the accessions. Monoploid genome sizes (Cx-value), average chromosome sizes (C/n-value), and GC content were determined. Haploid genome size of S. aethiopicum ranged from 1.312 pg/1C to 1.538 pg/1C., which is close to the genome size (1.2 pg/1C) of the common eggplant. Only PI 420226 (1.538 pg/1C) was significantly different from the rest, giving credence to the theory that PI 420226 is actually a S. macrocarpon accession. GC content of S. aethiopicum accessions was about 40%. We used 18S-28S rDNA and 5S rDNA probes to study the distribution and physical position of these ribosomal genes in S. aethiopicum. These results help to better understand intraspecific variability in S. aethiopicum and can be important for the breeding and selection of this crop.

This increase in disease severity in the northern United States has been attributed to increased utilization of no-till planting and changes in climate. A field study was conducted at the University of Tennessee, Research and Education Center in Milan, TN from 2007 to 2010 to determine severity in tilled and no-till plots treated with or without fungicide at R3 and R5 growth stages. Three FLS-susceptible cultivars, one each in Maturity Groups III, IV, and V, were treated with pyraclostrobin (Headline) fungicide. Analysis of variance using the area under the disease progress curve (AUDPC) indicated no significant difference (P [< or =, slant] 0.05) in disease severity between tilled and no-till plots without fungicide. Fungicide did not significantly reduce disease under no-till, but did under tilled plots. This is the first study showing that no-till plots did not reduce or enhance the severity of FLS when no fungicide was applied. Fungicide application significantly reduced (P [< or equal, slant] 0.05) disease severity and AUDPC and increased yield in tilled plots. The yield gains in tilled, fungicide-treated plots ranged from 1 to 17%. When fungicide was applied, disease severity was not reduced as significantly in no-till as in treated tilled plots, suggesting that fungicide programs under a notill system may require further study to minimize the risk of FLS severity.

The pathogen is believed to incite infections in the field, and disease symptoms become evident only during storage. To determine the timing of apple fruit infection in relation to development of speck rot in storage, 'Red Delicious' and 'Fuji' apple fruit were inoculated in the orchard with P. washingtonensis at different times during the growing season, harvested, and monitored for decay development during storage at 0[degrees]C. Fruit inoculated in both field and laboratory also were used to identify the infection courts and mode of apple fruit penetration by P. washingtonensis. In all 3 years, stem-end speck rot and calyx-end speck rot developed during cold storage on fruit inoculated during the growing season, regardless of inoculation time; and the incidence of total speck rot in storage increased as the fruit inoculation time approached harvest. On fruit floral parts, the pathogen colonized sepals at higher rates than stamens. Availability of naturally occurring necrotic tissues favored the colonization of the fungus on sepals. Histological studies indicated that infection occurred through micro-cracks on the surfaces of pedicels and sepals of the fruit, and invasion of these tissues was restricted between the cuticle and epidermis. Findings of this study will assist in the development of effective control strategies for speck rot.

Symptomatic (chlorosis, leaf curl, or vein banding) and non-symptomic leaves were selected from Apios americana, Cyamopsis tetragonolobus, Desmodium spp., Glycine max, Lablab purpureus, Lotus japonicus, Phaseolus coccineus, Phaseolus vulgaris, Vicia faba, Vigna ungulculata, and Chenopodium quinoa (an indicator species), and sent to Agdia Inc. for their Crop Screen: "Bean (Soybean)" tests. Cowpea mosaic virus (in L. purpureus), Southern bean mosaic virus (in A. americana), Soybean dwarf virus (in L. purpureus), and Tobacco streak virus (in Desmodium spp.) were identified. In addition, P. vulgaris was found positive in the serological Potyvirus group test, and was further characterized using reverse transcription (RT)-PCR using total RNA (Qiagen RNeasy extraction kit) from symptomatic leaves. A ~ l-kb fragment of virus genome was amplified using degenerate primers, forward: 5' TGYGTNGAYGAYYTYAAYAA 3' (3) and reverse: 5' TCRTARAARTCRAAIGCRTAICKIG 3' (2).

To determine whether several popular raspberry cultivars in Washington State differ in susceptibility to P. penetrans and whether post-plant nematicides treatments are warranted, five independent, multiyear trials were conducted. Trials in existing plantings of 'Cascade Bounty', 'Chemainus', 'Meeker' (two trials), and 'Saanich' raspberry were established in northwest Washington. Treated plots were protected from P. penetrans by applying nematicides over a 3-year period, while nontreated plots received no nematicides. P. penetrans population densities in soil and root samples were assessed spring and fall of each year. In addition, impact of P. penetrans on raspberry yield, fruit composition, cane production, and root biomass was measured several times in each cultivar during the 3-year study. P. penetrans root population densities in nematicide-treated plots were consistently lower than those in nontreated plots at all the samplings. There were few consistent treatment differences in fine root biomass, the preferred feeding sites for P. penetrans. However, a complete root system sampling of one of the cultivars did show greater fine root biomass in treated plants compared with nontreated plants. When differences were observed aboveground, treated plants yielded less than corresponding nontreated plants, indicating that the nematicides may have been phytotoxic to some of the cultivars. This study suggests that post-plant nematicide applications are of limited benefit because, at least during the 3-year time period of this study, there were few observable benefits of protecting these raspberry cultivars from P. penetrans.

Multiple mechanisms have been proposed to explain the discrepancies in energy balance including diurnal energy storage changes, advection of energy, and larger scale turbulent processes that cannot be resolved by field EC. To investigate the energy balance issue, we used a year of data from paired EC towers in irrigated sugarcane in Maui, Hawai'i, USA. The towers were in identical crops and cultivation practices and had similar climate with the notable exception of wind. One tower was in a location where nearby orographic features funneled Trade Winds, resulting in sustained, continuous turbulence. The other was in a leeward location with less turbulence, particularly at night (u*). We found significantly improved closure (8.5-10%) at both sites using daily sums of Available Energy in closure regressions as opposed to 30min data, illustrating the importance of storage terms. The energy budget closed for both fields when only days with continuous turbulence (all 30min u*>critical u*) were considered, with significantly larger uncertainty in the leeward field ( plus or minus 13%) due to the small number of days (n =13) with this condition. Significant energy imbalance appeared in both fields with even 30min of subcritical turbulence in a day, and each field had different turbulence-closure patterns. Closure with continuous turbulence was sensitive to choice of critical u*; an arbitrary u* of 0.1ms-1 resulted in non-closure. The results show the value of paired EC towers in contrasting turbulence conditions to assess energy budget closure.

Crop rotation and resistant cultivars are used to mitigate the damage of SCN, but these approaches are not completely successful because of the varied SCN populations. Thus, the limitations of these practices with soybean dictate investigation of other avenues of protection of soybean against SCN, perhaps through genetically engineering of broad resistance to SCN. For better understanding of the consequences of genetic manipulation, elucidation of SCN protein composition at the subunit level is necessary. We have conducted studies to determine the composition of SCN proteins using a proteomics approach in our laboratory using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) to separate SCN proteins and to characterize the proteins further using mass spectrometry. Our analysis resulted in the identification of several hundred proteins. In this investigation, we developed a web based database (SCNProDB) containing protein information obtained from our previous published studies. This database will be useful to scientists who wish to develop SCN resistant soybean varieties through genetic manipulation and breeding efforts.

The phylogenetically supported genera we recognize here in the Hygrophoraceae based on these and previous analyses are: Acantholichen, Ampulloclitocybe, Arrhenia, Cantharellula, Cantharocybe, Chromosera, Chrysomphalina, Cora, Corella, Cuphophyllus, Cyphellostereum, Dictyonema, Eonema, Gliophorus, Haasiella, Humidicutis, Hygroaster, Hygrocybe, Hygrophorus, Lichenomphalia, Neohygrocybe, Porpolomopsis and Pseudoarmillariella. A new genus that is sister to Chromosera is described as Gloioxanthomyces. Revisions were made at the ranks of subfamily, tribe, genus, subgenus, section and subsection. We present three new subfamilies, eight tribes (five new), eight subgenera (one new, one new combination and one stat. nov.), 26 sections (five new and three new combinations and two stat. nov.) and 14 subsections (two new, two stat. nov.). Species of Chromosera, Gliophorus, Humidicutis, and Neohygrocybe are often treated within the genus Hygrocybe; we therefore provide valid names in both classification systems. We used a minimalist approach in transferring genera and creating new names and combinations. Consequently, we retain in the Hygrophoraceae the basal cuphophylloid grade comprising the genera Cuphophyllus, Ampulloclitocybe and Cantharocybe, despite weak phylogenetic support. We include Aeruginospora and Semiomphalina in Hygrophoraceae based on morphology though molecular data are lacking. The lower hygrophoroid clade is basal to Hygrophoraceae s.s., comprising the genera Aphroditeola, Macrotyphula, Phyllotopsis, Pleurocybella, Sarcomyxa, Tricholomopsis and Typhula.

One option how to analyse this phenomenon is built up on the theory of social cleavages that inevitably affect the political relations within society. Therefore the election results are significantly differentiated depending on given space and temporal context. This article try to measure five socio-economic factors as ethnicity, religiosity, age, education and unemployment considering their influence on spatial pattern of electoral behaviour in given territorial units - at the statewide level of the Slovak Republic, but mainly its partial regions. For this reason, analytical instruments of spatial econometrics are applied, which pose the most appropriate tools to examine aggregate data duly regarding the geographical nexus of presented phenomena. The Spatial Durbin model is utilised for evaluating the linkage between socio-economic determinants of electoral behaviour and parliamentary elections' results held in Slovak Republic after 1998. In this paper we focus on the extent of regressors' explanatory power forming the territorial picture of electoral outcomes in western part of the country and define the socio-political profile of regions, which are situated there.

Gene-environment (GxE) interactions are one of these contributors and in the guise of diet and physical activity are important modulators of cardiometabolic phenotypes and ensuing diseases. Results: We mined the scientific literature to collect GxE interactions from 386 publications for blood lipids, glycemic traits, obesity anthropometrics, vascular measures, inflammation and metabolic syndrome, and introduce CardioGxE, a gene-environment interaction resource. We then analyzed the genes and SNPs supporting cardiometabolic GxEs in order to demonstrate utility of GxE SNPs and to discern characteristics of these important genetic variants. We were able to draw many observations from our extensive analysis of GxEs. 1) The CardioGxE SNPs showed little overlap with variants identified by main effect GWAS, indicating the importance of environmental interactions with genetic factors on cardiometabolic traits. 2) These GxE SNPs were enriched in adaptation to climatic and geographical features, with implications on energy homeostasis and response to physical activity. 3) Comparison to gene networks responding to plasma cholesterol-lowering or regression of atherosclerotic plaques showed that GxE genes have a greater role in those responses, particularly through high-energy diets and fat intake, than do GWAS-identified genes for the same traits. Other aspects of the CardioGxE dataset were explored. Conclusions: Overall, we demonstrate that SNPs supporting cardiometabolic GxE interactions often exhibit transcriptional effects or are under positive selection. Still, not all such SNPs can be assigned potential functional or regulatory roles often because data are lacking in specific cell types or from treatments that approximate the environmental factor of the GxE. With research on metabolic related complex disease risk embarking on genome-wide GxE interaction tests, CardioGxE will be a useful resource.

Restoration of mixed-oak (Quercus spp.) forest is also a concern because of widespread oak regeneration failure, especially on moist, productive sites where competition from faster-growing tree species is fierce following stand-replacing disturbances. Several silvicultural methods are proposed to promote oak regeneration but many are not experimentally tested, especially on productive sites. We surveyed birds in 19 stands to assess response to initial application of three proposed oak regeneration treatments on productive sites: prescribed burning (B); oak shelterwood by midstory herbicide (OSW); shelterwood harvests (SW); and controls (C), for one breeding season before, and two breeding seasons after, implementation. Relative density of successional-scrub species Indigo Buntings (Passerina cyanea), Eastern Towhees (Pipilo erythrophthalmus), and Chestnut-sided Warblers (Setophaga pensylvanica) increased, while Ovenbirds (Seiurus aurocapilla) decreased within 11 to 18 months after SW harvests; understory disturbance treatments B or OSW had no effect. Our results indicated that partial harvests created habitat for breeding birds associated with both young and mature forests, whereas understory treatments had little effect. Additionally, we show that even small patches of young forest habitat are used by more individuals and more species of breeding birds than surrounding closed-canopy forest, and may benefit successional-scrub species by enabling their occurrence in an otherwise forested landscape. Absence of several lower-elevation successional-scrub bird species in our mid-elevation SW harvests suggests that comprehensive conservation in the southern Appalachians necessitates creating and maintaining young forest habitats across elevation gradients.

AN - 1626162241; 25401762 AB - ATP-binding cassette (ABC) transporters are a large superfamily of proteins that mediate diverse physiological functions by coupling ATP hydrolysis with substrate transport across lipid membranes. In insects, these proteins play roles in metabolism, development, eye pigmentation, and xenobiotic clearance. While ABC transporters have been extensively studied in vertebrates, less is known concerning this superfamily in insects, particularly hemipteran pests. We used RNA-Seq transcriptome sequencing to identify 65 putative ABC transporter sequences (including 36 full-length sequences) from the eight ABC subfamilies in the western tarnished plant bug (Lygus hesperus), a polyphagous agricultural pest. Phylogenetic analyses revealed clear orthologous relationships with ABC transporters linked to insecticide/xenobiotic clearance and indicated lineage specific expansion of the L. hesperus ABCG and ABCH subfamilies. The transcriptional profile of 13 LhABCs representative of the ABCA, ABCB, ABCC, ABCG, and ABCH subfamilies was examined across L. hesperus development and within sex-specific adult tissues. All of the transcripts were amplified from both reproductively immature and mature adults and all but LhABCA8 were expressed to some degree in eggs. Expression of LhABCA8 was spatially localized to the testis and temporally timed with male reproductive development, suggesting a potential role in sexual maturation and/or spermatozoa protection. Elevated expression of LhABCC5 in Malpighian tubules suggests a possible role in xenobiotic clearance. Our results provide the first transcriptome-wide analysis of ABC transporters in an agriculturally important hemipteran pest and, because ABC transporters are known to be important mediators of insecticidal resistance, will provide the basis for future biochemical and toxicological studies on the role of this protein family in insecticide resistance in Lygus species.

AN - 1624935129; 25383623 AB - The manufacturing processes of royal demolition explosive (RDX), or hexahydro-1,3,5-trinitro-1,3,5-triazine, have resulted in serious water contamination. As a potential carcinogen, RDX can cause a broad range of harmful effects to humans and animals. The ovine rumen is capable of rapid degradation of nitroaromatic compounds, including RDX. While ruminal RDX-degrading bacteria have been identified, the genes and pathways responsible for RDX degradation in the rumen have yet to be characterized. In this study, we characterized the metabolic potential of the ovine rumen using metagenomic approaches. Sequences homologous to at least five RDX-degrading genes cloned from environmental samples (diaA, xenA, xenB, xplA, and xplB) were present in the ovine rumen microbiome. Among them, diaA was the most abundant, likely reflective of the predominance of the genus Clostridium in the ovine rumen. At least ten genera known to harbor RDX-degrading microorganisms were detectable. Metagenomic sequences were also annotated using public databases, such as Pfam, COG, and KEGG. Five of the six Pfam protein families known to be responsible for RDX degradation in environmental samples were identified in the ovine rumen. However, increased substrate availability did not appear to enhance the proliferation of RDX-degrading bacteria and alter the microbial composition of the ovine rumen. This implies that the RDX-degrading capacity of the ovine rumen microbiome is likely regulated at the transcription level. Our results provide metagenomic insights into the RDX-degrading potential of the ovine rumen, and they will facilitate the development of novel and economic bioremediation strategies.

AN - 1624932817; 25386688 AB - Halyomorpha halys (Stål) (Heteroptera: Pentatomidae), the brown marmorated stink bug, is an invasive agricultural and nuisance pest rapidly expanding its incidence in North America. This voracious pest poses a significant threat to rural and urban agriculture, especially to specialty crops such as apples, grapes and ornamentals, as well as staple crops including soybean and corn. The object of this study was to generate transcript sequence resources for H. halys. RNA-seq libraries derived from distinct developmental stages and sexes were sequenced and assembled into 248,569 putatively unique transcripts (PUTs). PUTs were segmented into three disjoint tiers of varying reliability, with 4,794 classified as gold tier (highest quality), 16,878 as silver, and 14,357 as bronze. The gold-tier PUTs associated with 2,580 distinct non-redundant protein sequences from the NCBI NR database--1,785 of these (69%) mapped to annotated UniProtKB database proteins, from which 1,273 unique Pfam families and 459 unique Molecular Function GO terms were encountered. Of the silver tier's 6,527 PUTs associated with unique proteins, 4,193 mapped to UniProtKB (64%), from which 1,941 and 640 unique Pfam and Molecular Function GO terms were extracted. H. halys PUTs related to important life processes like immunity, endocrinology, reproduction, development, behavior, neurotransmission, neurotoxicity, olfaction, and small RNA pathways were validated through quantitative Real-Time PCR (qRT-PCR) for differential expression during distinct life stages (eggs, 2nd instar nymphs, 4th instar nymphs, female adults, male adults). PUTs similar to hypothetical proteins identified in symbiont microbes, including Pantoea and Nosema species, were more abundantly expressed in adults versus nymphs. These comprehensive H. halys transcriptomic resources can be utilized to aid development of novel control methodologies to disrupt life processes; to conduct reverse genetic screens to determine host gene function; and to design environmentally unobtrusive means to control host populations or target specific H. halys life stages, such as molecular biopesticides.

This study sought to determine the effect of four no-till cropping systems differing in rotation length and crop diversity on near-surface (0 to 10 cm) soil properties. Cropping system treatments included small grain-fallow (SG-F) and three continuously cropped rotations (3 yr, 5 yr, and Dynamic) located in south-central North Dakota, USA. Soil pH was lower in the 3 yr rotation (5.17) compared to the Dynamic (5.51) and SG-F (5.55) rotations (P< or =0.05). Among cropping system treatments, 5 yr and Dynamic rotations possessed significantly greater soil organic C (SOC) and total N (mean = 26.3 Mg C ha super(-1) , 2.5 Mg N ha super(-1) ) compared to the 3 yr (22.7 Mg C ha super(-1) , 2.2 Mg N ha super(-1) ) and SG-F (19.9 Mg C ha super(-1) , 2.0 Mg N ha super(-1) ) rotations (P< or =0.05). Comparison of SOC measured in this study to baseline values at the research site prior to the establishment of treatments revealed only the 5 yr and Dynamic rotations increased SOC over time. The results of this study suggest that a diverse portfolio of crops is necessary to minimize soil acidification and increase SOC.

The discovery of P. graminis subsp. graminis race Ug99, which overcomes previously effective resistance in wheat, raises concerns for global wheat production and food security. There is currently no mathematical model that describes the duration of the WSR latent period based on temperature or heat units. A study using P. graminis subsp. graminis race GFCDC in 'Stephens' wheat was conducted at a range of temperatures (from 4.7 to 33.4[degrees]C), to determine their effect on latent period duration. There were significant differences in latent period duration among temperatures, and temperatures above 30[degrees]C generally were not conducive for pustule development. A mathematical model to predict latent period duration based on temperature was formulated; the model can be applied to data consisting of varying temperature readings measured at any desired time increment. The model was validated in outdoor experiments under natural conditions on Stephens and 'McNair' wheat. In field and outdoor experiments, the latent period durations predicted with the model were within 16 h of the observed latent period, and most fell into the 99% confidence interval of the observations. For experiments conducted on field-grown plants, no significant differences were found between predicted and observed latent period duration. Factorial experiments conducted under growth chamber conditions, using four wheat cultivars (Stephens, McNair 701, 'Scout 66', and 'Kingbird') and four P. graminis subsp. graminis races (GCCNC, GCCSC, QFCSC, and GFCDC) at three temperatures (5, 15 and 30[degrees]C) showed significant differences among cultivars at each temperature. A quantitative model for latent period duration could help in estimating epidemic development, and also in improving our understanding of WSR epidemiology.

When these lines were assessed for resistance to Fusarium thapsinum stalk rot, a cause of lodging, they were as resistant to F. thapsinum as the near-isogenic wild type. Peduncles of newly identified bmr lines from an ethyl-methanesulfonate-mutagenized population, inoculated with F. thapsinum, were as resistant as the wild-type line, BTx623. One bmr line (1107) had significantly smaller mean lesion lengths than BTx623, suggesting that a mutation is associated with reduced susceptibility. Growing F. thapsinum on medium with ferulic, vanillic, sinapic, syringic, and caffeic acids (phenolic compounds derived from the lignin pathway and elevated in different bmr lines) indicated that F. thapsinum was tolerant to these compounds. When eight other sorghum fungi were tested for response to the presence of these compounds, ferulic acid inhibited these fungi. Most of the phenolics inhibited F. verticillioides and F. proliferatum. Accumulation of phenolic metabolites in bmr plants may inhibit growth of some sorghum pathogens, while other factors such as aromatic phytoalexins or salicylic acid may be involved in resistance to F. thapsinum.

This study aimed to identify parental, child and neighborhood factors influencing longitudinal assessments of body mass index (BMI) and activity patterns among Latino children, and to estimate lagged and cross-lagged effects between child BMI, %MVPA and %SED. Methods: A longitudinal design with assessments at baseline, 1 and 2 years follow-up (FU) was used to evaluate the effects of maternal and paternal factors (BMI, age, education level, acculturation, household income and household size), child factors (gender, age, BMI, pubertal status) and neighborhood factors (disorder, victimization) on child BMI, %MVPA and %SED, expressed as a percent of awake time, in 282 Latino children ages 8-10 y and their parents. This study was restricted to families with a mother and biological father or father figure in the child's life. Results: Across time, total daily accelerometer counts (p = 0.04) and steps decreased (p = 0.0001), %SED increased (p = 0.0001), and %MVPA decreased (p = 0.02). Moderate lagged effects or tracking was seen for %MVPA and %SED (p = 0.001). %MVPA varied by gender (5.5% higher in boys than girls, p = 0.0001); child age (-0.4% per year, p = 0.03), and child BMI in boys only (-0.22%, p = 0.0002). Negative effects of paternal age, maternal education and maternal changes in BMI on %MVPA also were seen. %SED increased with child age (2.5% higher per year, p = 0.0001). Positive effects of paternal acculturation, maternal change in BMI, paternal age, and negative effects of household size on %SED were observed. A cross-lagged positive effect of BMI at FU1 on %SED at FU2 was observed for boys and girls (p = 0.03). Neighborhood disorder and victimization were not significant predictors of child BMI, %MVPA or %SED. Conclusion: The major child determinants of physical activity (age, gender and BMI) and minor parental influences (maternal BMI and education, paternal age and acculturation) should be considered in designing interventions to promote %MVPA and reduce %SED among Latino children as they approach adolescence.

This study was designed to examine growth of red imported fire ant colonies (Solenopsis invicta Buren) on four artificial diets: a chemically undefined "oligidic" predator diet, two partly defined "meridic" diets utilized by Bhatkar and Whitcomb (Florida Entomol. 53: 229-232, 1970) and Dussutour and Simpson (Insect. Soc. 55: 329-333, 2008) for Solenopsis fire ants and Rhytido-ponera ants, respectively, and finally a completely chemically defined "holidic" diet utilized by Straka and Feldhaar (Insect. Soc. 54:100-104, 2007a, Insect. Soc. 54:202, 2007b Erratum) for carpenter ants. Crickets and sugar water were used as a standard diet. After 6 weeks, fire ant colonies fed crickets and sugar water were healthy and had grown considerably. In contrast, colonies fed the artificial diets showed little or no growth demonstrating that these diets are not suitable for rearing healthy fire ant colonies. Nevertheless, the holidic or entirely synthetic Straka diet may provide a suitable basis for further studies of fire ant dietary requirements because it resulted in modest production of all brood stages. We advise caution in using diets that mix sugar and protein into a single "all in one" diet because workers and brood have differing dietary requirements.

Little is known about their biology on a molecular-genetic level, including components of their immune system. Because the insect immune response is involved with important processes such as gut microbial homeostasis and vector competence, our aims were to identify components of the midge innate immune system and examine their expression profiles in response to diet across time. Methods: In our previous work, we de novo sequenced and analyzed the transcriptional landscape of female midges under several feeding states including teneral (unfed) and early and late time points after blood and sucrose. Here, those transcriptomes were further analyzed to identify insect innate immune orthologs, particularly humoral immune response elements. Additionally, we examined immune gene expression profiles in response to diet over time, on both a transcriptome-wide, whole-midge level and more specifically via qRTPCR analysis of antimicrobial peptide (AMP) expression in the alimentary canal. Results: We identified functional units comprising the immune deficiency (Imd), Toll and JAK/STAT pathways, including humoral factors, transmembrane receptors, signaling components, transcription factors/regulators and effectors such as AMPs. Feeding altered the expression of receptors, regulators, AMPs, prophenoloxidase and thioester-containing proteins, where blood had a greater effect than sucrose on the expression profiles of most innate immune components. qRTPCR of AMP genes showed that all five were significantly upregulated in the alimentary canal after blood feeding, possibly in response to proliferating populations of gut bacteria. Conclusions: Identification and functional insight of humoral/innate immune components in female C. sonorensis updates our knowledge of the molecular biology of this important vector. Because diet alone influenced the expression of immune pathway components, including their effectors, subsequent study of the role of innate immunity in biological processes such as gut homeostasis and life history are being pursued. Furthermore, since the humoral response is a key contributor in gut immunity, manipulating immune gene expression will help in uncovering genetic components of vector competence, including midgut barriers to infection. The results of such studies will serve as a platform for designing novel transmission-blocking strategies.

The distribution of these taxa in western North America, and their mode of invasion, is relatively unresolved. Using amplified fragment length polymorphisms of 858 plants from 131 populations from British Columbia to California to South Dakota, we determined that Bohemian knotweed was the most common taxon (71 % of all plants). This result is in contrast to earlier reports of F. bohemica being uncommon or non-existent in the USA, and also differs from the European invasion where it is rarer. Japanese knotweed was monotypic, while giant knotweed and Bohemian knotweed were genetically diverse. Our genetic data suggest that Japanese knotweed in western North America spreads exclusively by vegetative reproduction. Giant knotweed populations were mostly monotypic, with most containing distinct genotypes, suggesting local spread by vegetative propagules, whereas Bohemian knotweed spreads by both seed and vegetative propagules, over both long and short distances.

It is not clear why some parents restrict their children's screen use and others do not. Parent's outcome expectations for allowing their child to watch TV and other screen media, i.e. the perceived 'costs' and 'benefits,' may be influential. Our objective was to develop a measure of Parent's Outcome Expectations for Children's TV Viewing (POETV) and test the psychometrics of the resulting instrument among parents with children 6-12 years old. Methods: An ethnically diverse sample (n = 311) of parents from Harris County, Texas completed measures for POETV, demographics, and parent and child TV viewing and other screen media use via an internet survey. The sample was randomly split and an exploratory factor analysis (EFA) was conducted among the first half of the sample separately for Positive and Negative POETV. A confirmatory factor analysis (CFA) assessed the fit of the resulting factors with the data in the second half of the sample. Internal reliabilities and Spearman partial correlations (controlling for confounders) of children's TV and other screen use with the resulting POETV factors were calculated for the full sample. Results: EFA identified two factors for Positive POETV (Parent Centered; Child Centered) and two factors for Negative POETV (TV & Content Exposure; Prevent Other Activities). Follow up CFA confirmed moderate to good psychometric properties for both factor structures with the addition of four correlated errors in the Positive POETV model. Internal reliabilities were appropriate (Cronbach's alpha >0.7). Parent Centered Positive POETV and Child Centered Positive POETV were correlated with children's TV viewing on weekdays (0.14, p < 0.05) and weekends (0.17, p < 0.01) respectively. Both also correlated with other screen media use on weekends (0.20 and 0.21, p < 0.001). Prevent Other Activities Negative POETV was negatively correlated with children's TV viewing on weekdays (-0.16, p < 0.01), weekends (-0.14, p < 0.05) and other screen media on weekends (-0.14, p < 0.05). Conclusions: The Positive and Negative POETV scales offer a new tool to better define predictors of screen media parenting practices and child screen media use behaviors.

A rise in ambient temperature and carbon dioxide (CO2) may have various impacts on arthropods such as altered life cycles, modified reproductive patterns, and changes in distribution. The sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is a global pest responsible for significant losses of agricultural yields annually. This study was conducted to determine the impacts of changing temperature and CO2 levels on selected life history parameters of B. tabaci biotype B. Populations were established at three temperature regimes (25,28, and 33 degree C), and each population was evaluated in all three environments. Collard, Brassica oleracea ssp. acephala de Condolle (Brassicaceae), was used as the host. These results were based on data from 5 to approximately 30 generations. Oviposition, nymphal survival, and reproduction were significantly affected by temperature, with net reproductive success declining to 36.4% at 33 degree C. Overall, 28 degree C was most favorable for whitefly fitness. However, the optimal temperature for B. tabaci reproduction may be between 28 and 33 degree C. There were no temperature effects on total nonstructural carbohydrate concentrations in collard, and impacts of the host plant on whitefly development in the different environments were determined to be minimal. An environment of enriched CO2 (750 ppm) was not observed to have an adverse effect on whitefly reproduction. Temperature was negatively correlated with adult body size. Length and width of males and females were affected by temperature. Data regarding population dynamics of B. tabaci in response to climate change are important for accurate predictions and improving management practices.

Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies is to be justified. As irrigation has increased, the number of university research and extension personnel as well as the number of US Department of Agriculture personnel in the Agricultural Research Service and Natural Resources Conservation Service has not kept pace with the increase and the resulting challenges. A combined state and federal response to these challenges is needed to provide appropriate and effective problem solutions that ensure efficient water use and high crop water productivity while protecting water supplies and the environment.

The analysis focuses on manually sampled data from 21 snow surveys covering 11 years at the drift-dominated Reynolds Mountain East catchment (0.36 km super(2)) in southwestern Idaho, USA. Surveys were conducted midwinter and in early spring. Interseason and intraseason trends were examined along with the time stability of distributions, goodness-of-fit to theoretical distributions, and the representativeness of an index site as a measure of basin-wide snow water equivalent. The average snow depth coefficient of variation (CV) over the entire time period was 0.71, which is in accordance with broad regional assessments. Higher wind speeds during snow events and increased melt led to increased heterogeneity and higher CVs. Forested sites produced lower CVs presumably due to moderated winds at these sites. Consistent wind directions produced accumulation patterns that were very stable from year-to-year. Many previous studies have suggested that vital subgrid snow heterogeneity in large-scale models can be approximated with parametric distributions. Gamma distributions were preferred over lognormal distributions in describing the overall distribution while in tree-covered regions with less variability there was little difference between the two. It was also found that an index site, akin to the majority of North American mountain weather observation stations, provided a reasonable approximation of catchment-averaged SWE in most years. However, the reliability of this measure decreased in years that deviated from normal patterns.

Like other members of Liberibacter, Lso-ZC1 encodes a flagellin domain-containing protein (Fla sub( Lso )) with a conserved 22 amino-acid peptide (flg22 sub( Lso )). To understand the innate immune responses triggered by this unculturable intracellular bacterium, we studied the pathogen-associated molecular patterns (PAMPs) that triggered immunity in Nicotiana benthamiana, using the flg22 sub( Lso ) peptide and the full length fla sub( Lso ) gene. Results: Our results showed that the expression of fla sub( Lso ) via Agrobacterium-mediated transient expression induced a slow necrotic cell death in the inoculated leaves of N. benthamiana, which was coupled with a burst of reactive oxygen species (ROS) production. Moreover, the expression of several representative genes involved in innate immunity was transiently up-regulated by the flg22 sub( Lso ) in N. benthamiana. The Fla sub( Lso ), however, induced stronger up-regulation of these representative genes compared to the flg22 sub( Lso ), especially that of flagellin receptor FLAGELLIN SENSING2 (FLS2) and respiratory burst oxidase (RbohB) in N. benthamiana. Although neither cell death nor ROS were induced by the synthetic flg22 sub( Lso ), a weak callose deposition was observed in infiltrated leaves of tobacco, tomato, and potato plants. Conclusion: The flagellin of Lso and its functional domain, flg22 sub( Lso ) share characteristics of pathogen-associated molecular patterns, and trigger unique innate immune responses in N. benthamiana. Slow and weak activation of the innate immune response in host plants by the flagellin of Lso may reflect the nature of its intracellular life cycle. Our findings provide new insights into the role of the Lso flagellin in the development of potato zebra chip disease and potential application in breeding for resistance.

The performance of such systems can be degraded by the incorrect specification of parameters describing modeling and observation errors. Here the Auto-Tuned Land Data Assimilation System (ATLAS) is introduced to simultaneously solve for all parameters required for the application of a simple land data assimilation system to integrate satellite-based rainfall and soil moisture retrievals for drought monitoring applications. The approach is based on combining a triple collocation (TC) strategy with the statistical analysis of filtering innovations and designed to leverage the simultaneous availability of satellite-based soil moisture products acquired from both active and passive microwave remote sensing. A number of variants of the ATLAS approach-each based on a different strategy for leveraging TC and innovation analysis within an adaptive filtering framework-are derived and evaluated through a synthetic twin experiment. In addition, a preliminary real data analysis is conducted using actual satellite-based products and evaluated against independent ground-based observations. Results illustrate the potential of ATLAS to improve the analysis of soil moisture anomalies using data products derived from the Global Precipitation Measurement (GPM) and the NASA Soil Moisture Active/Passive missions.

Current systems are limited by installation depth and labor, accuracy, and cost. Time domain reflectometry (TDR) is an approach for monitoring soil water content that relates the travel time of an electromagnetic pulse on a waveguide to the water content of the soil. This article discusses the design, installation, lab testing, and field testing of a novel TDR sensor, using a multi-segmented, waveguide-on-access-tube (WOAT) geometry. The segmented WOAT approach allows for ease of assembly and installation of the sensor stack to the desired depth. Additionally, this sensor incorporates circuits embedded in the sensor body itself, directly coupled to the waveguides, eliminating problems associated with cabling encountered in previous WOAT embodiments. Despite some initial problems with mechanical strength of the prototype sensors, the WOAT equipment provided quality TDR waveforms and long-time reflection coefficients on a daily basis at multiple depths over the course of several months, providing data for both soil water content and bulk electrical conductivity estimates. When properly calibrated, the WOAT data were comparable to concurrent measurements of soil water content using a neutron probe, though there were differences due to the disparity in sensing volumes. Overall, we show that this is a promising new sensor design.

Groundwater withdrawal was measured for two years on six dairy farms with 660 to 6400 milk cows in southern Idaho. Groundwater withdrawal was calculated on an equivalent cow basis to account for relative differences in the numbers of milk cows, dry cows, heifers, and calves on each farm. Average groundwater withdrawal from each dairy varied from 110 to 250 L d super(1) eq. cow super(-1) with an overall average of 190 L d super(-1) eq. cow super(1-) for the six farms. On an area basis, groundwater withdrawal varied from 180 to 880 mm y super(-1) on each farm with a mean of 530 mm y super(-1). Estimated annual irrigation requirements in southern Idaho are 510 mm for spring barley, 590 for corn, and 920 for alfalfa. Wastewater that was available for irrigation was only measured on three farms and varied from 21 to 150 L d super(1) eq. cow super(-1), with the highest amounts from a freestall dairy. Assuming that wastewater replaced a portion of groundwater used for irrigation, the net groundwater used on these three dairies was 290 to 370 mm y super(-1). Data from these six dairies indicated that groundwater withdrawal by dairy farms was similar or less than the amount of water required to meet evapotranspiration needs of irrigated crops in southern Idaho, especially if wastewater is used to offset irrigation and is not applied in addition to irrigation.

Physical activity (PA) can help prevent obesity. Parents can influence children's PA through parenting practices. This study aimed to examine the independent contributions of (1) sociodemographic, (2) cultural, (3) parent perceived environmental, and (4) objectively measured environmental factors, to PA parenting practices. Methods: A cross-sectional sample of Latino parents (n = 240) from Harris County, TX in 2011-2012 completed validated questionnaires to assess PA parenting practices, acculturation, familism, perception of their neighborhood environment, and demographics. Home addresses were mapped and linked to Census block-level crime and traffic data. Distance to the closest park was mapped by GIS. Regression models were built in a hierarchical step-wise fashion. Results: Combined models showed R super(2) of 6.8% to 38.9% for different parenting practices. Significant correlations included sociodemographic variables with having outdoor toys available, psychological control, and promotion of inactivity. Cultural factors correlated with PA safety concern practices. Perceived environmental attributes correlated with five of seven parenting practices, while objectively-measured environmental attributes did not significantly correlate with PA parenting practices. Conclusion: Interventions promoting PA among Latino preschoolers may need to address the social-ecological context in which families live to effectively promote PA parenting, especially parents' perceptions of neighborhoods.

Following less than 3 h of training, forest staff from a range of professional backgrounds used Pro-B in an operational-scale field study to apply single-tree selection and group selection systems in longleaf pine (Pinus palustris Mill.) stands. Field crews achieved precision levels often within 3%-5% of the 11.5 m super(2).ha super(-1) target residual basal area. By aggregating many diameter classes into only three diameter-class groups, Pro-B improves efficiency by requiring tree markers to remember only three fractions, while making a single pass through the stand. Trees of large size, specific species and with good form, broad crowns and cavities can be retained, while adjusting spacing to release residuals. Systematic quantification of marking trees for removal enables different individuals to obtain similar results. Early observations revealed encouraging levels of pine regeneration and stand development, along with continuing good volume growth rates of 3% per year. Although less certain until one or more cutting cycles are completed, these early tests indicate that a stable mature forest structure should develop, which is characterized by the presence of large trees and natural regeneration.Original Abstract: La surface terriere proportionnelle (ST-Pro) est une methode precise et facile d'utilisation qui a ete mise au point pour que la sylviculture inequienne devienne une option pratique d'amenagement. Avec moins de trois heures d'entrainement, du personnel forestier provenant de divers milieux professionnels a utilise ST-Pro dans le cadre d'une etude de terrain a l'echelle operationnelle pour appliquer les systemes de jardinage par pied d'arbre et par groupe a des peuplements de pin des marais (Pinus palustris Mill.). Les equipes de terrain ont souvent atteint des niveaux de precision variant entre 3 et 5 % de la valeur cible de surface terriere residuelle qui etait de 11,5 m super(2).ha super(-1). En regroupant plusieurs classes de diametre en seulement trois groupes, la ST-Pro augmente l'efficacite en demandant aux marteleurs de ne retenir que trois fractions lors de leur passage unique dans le peuplement. Des arbres de grande taille, d'especes particulieres et ayant une belle forme, une large cime et des cavites peuvent etre retenus tout en ajustant l'espacement entre les arbres residuels. La quantification systematique des arbres marques pour la recolte permet a differentes personnes d'obtenir des resultats similaires. Des observations preliminaires ont montre que la regeneration en pin et le developpement des peuplements montraient des signes encourageants tout en maintenant un bon taux de croissance en volume de 3 % par annee. Bien que les resultats soient incertains jusqu'a ce qu'au moins un cycle de coupe soit complete, ces tests preliminaires indiquent qu'une structure stable de foret mature devrait se developper, ce qui se caracterise par la presence de gros arbres et de regeneration naturelle.

Lactobacillus species are the predominant contaminants that decrease the profitability of biofuel production by reducing ethanol yields and causing "stuck" fermentations, which incur additional economic losses via expensive antibiotic treatments and disinfection costs. The current use of antibiotic treatments has led to the emergence of drug-resistant bacterial strains, and antibiotic residues in distillers dried grains with solubles (DDGS) are a concern for the feed and food industries. This underscores the need for new, non-antibiotic, eco-friendly mitigation strategies for bacterial contamination. The specific objectives of this work were to (1) express genes encoding bacteriophage lytic enzymes (endolysins) in Saccharomyces cerevisiae, (2) assess the lytic activity of the yeast-expressed enzymes against different species of Lactobacillus that commonly contaminate fuel ethanol fermentations, and (3) test the ability of yeast expressing lytic enzymes to reduce Lactobacillus fermentum during fermentation. Implementing antibiotic-free strategies to reduce fermentation contaminants will enable more cost-effective fuel ethanol production and will impact both producers and consumers in the farm-to-fork continuum. Results: Two genes encoding the lytic enzymes LysA and LysA2 were individually expressed in S. cerevisiae on multi-copy plasmids under the control of a galactose-inducible promoter. The enzymes purified from yeast were lytic against Lactobacillus isolates collected from fermentors at a commercial dry grind ethanol facility including Lactobacillus fermentum, Lactobacillus brevis, and Lactobacillus mucosae. Reductions of L. fermentum in experimentally infected fermentations with yeast expressing LysA or LysA2 ranged from 0.5 log sub(10) colony-forming units per mL (CFU/mL) to 1.8 log sub(10) (CFU/mL) over 72 h and fermentations treated with transformed yeast lysate showed reductions that ranged from 0.9 log sub(10) (CFU/mL) to 3.3 log sub(10) (CFU/mL). Likewise, lactic acid and acetic acid levels were reduced in all experimentally infected fermentations containing transformed yeast (harboring endolysin expressing plasmids) relative to the corresponding fermentations with untransformed yeast. Conclusions: This study demonstrates the feasibility of using yeast expressing bacteriophage endolysins to reduce L. fermentum contamination during fuel ethanol fermentations.

We used pit trap live removals in early autumn to estimate relative abundances of surface-active salamanders before and after 3 levels of riparian buffer retention (strip, patch, and no-buffer clear-cut) with upland regeneration harvest. The study spanned a pre-treatment year, the harvest year after logging, and 2 post-treatment years (post1, post2). We observed reduced average tree canopies and increased average down-wood cover along streams that received the buffer treatments, especially in the cut portion of patch buffer and no-buffer clear-cut treatments. Compared to pre-treatment, mean salamander relative abundance was lower in no-buffer treatments in the harvest year and in the post2 year, but not the post1 year. Weather differences between years likely partially influenced these results. Plethodon vehiculum abundance in the no-buffer clear-cut treatment was lower than in both the control units in post2 and patch buffer treatments during the harvest year and post2 year. Retention of existing down-wood and recruitment of post-treatment down-wood may have ameliorated treatment effects on P. vehiculum abundances in patch buffers by maintaining microclimates and microhabitats. In the no-buffer clear-cut treatments, however, there was no similarly-moderating influence (no effect) from down-wood except when mediated by higher rainfall and cooler conditions. It appears that maintaining amounts of dead down-wood in no-buffer clear-cut treatments and the cut areas of patch buffers that averaged amounts 3 to 6 times greater than occurred before buffer creation along these headwater streams may help lessen initial treatment effects on these woodland salamanders.

AN - 1554472938; 25127450 AB - Destruxins (DTXs) are cyclic depsipeptides produced by many Metarhizium isolates that have long been assumed to contribute to virulence of these entomopathogenic fungi. We evaluated the virulence of 20 Metarhizium isolates against insect larvae and measured the concentration of DTXs A, B, and E produced by these same isolates in submerged (shaken) cultures. Eight of the isolates (ARSEF 324, 724, 760, 1448, 1882, 1883, 3479, and 3918) did not produce DTXs A, B, or E during the five days of submerged culture. DTXs were first detected in culture medium at 2-3 days in submerged culture. Galleria mellonella and Tenebrio molitor showed considerable variation in their susceptibility to the Metarhizium isolates. The concentration of DTXs produced in vitro did not correlate with percent or speed of insect kill. We established endophytic associations of M. robertsii and M. acridum isolates in Vigna unguiculata (cowpeas) and Cucumis sativus (cucumber) plants. DTXs were detected in cowpeas colonized by M. robertsii ARSEF 2575 12 days after fungal inoculation, but DTXs were not detected in cucumber. This is the first instance of DTXs detected in plants endophytically colonized by M. robertsii. This finding has implications for new approaches to fungus-based biological control of pest arthropods.

This is traditionally done by the consumption of probiotics, live microbial food supplements. However, an alternative, and often very effective approach, is the consumption of food ingredients known as prebiotics. Fructans and arabinoxylans are naturally occurring non-digestible oligosaccharides in wheat that exhibit prebiotic properties and may enhance intestinal iron (Fe) absorption. The aim of this study was to assess the effect of prebiotics from wheat on Fe bioavailability in vitro (Caco-2 cells) and in vivo (broiler chickens, Gallus gallus). Methods: In the current study, the effect of intra-amniotic administration of wheat samples extracts at 17 d of embryonic incubation on the Fe status and possible changes in the bacterial population in intestinal content of broiler hatchlings were investigated. A group of 144 eggs were injected with the specified solution (1 ml per egg) into the amniotic fluid. Immediately after hatch (21 d) and from each treatment group, 10 chicks were euthanized and their small intestine, liver and cecum were removed for relative mRNA abundance of intestinal Fe related transporters, relative liver ferritin amounts and bacterial analysis of cecal content, respectively. Results: The in vivo results are in agreement with the in vitro observations, showing no differences in the hatchling Fe status between the treatment groups, as Fe bioavailability was not increased in vitro and no significant differences were measured in the intestinal expression of DMT1, Ferroportin and DcytB in vivo. However, there was significant variation in relative amounts of bifidobacteria and lactobacilli in the intestinal content between the treatments groups, with generally more bifidobacteria being produced with increased prebiotic content. Conclusions: In this study we showed that prebiotics naturally found in wheat grains/bread products significantly increased intestinal beneficial bacterial population in Fe deficient broiler chickens. With this short-term feeding trial we were not able to show differences in the Fe-status of broilers. Nevertheless, the increase in relative amounts of bifidobacteria and lactobacilli in the presence of wheat prebiotics is an important finding as these bacterial populations may affect Fe bioavailability in long-term studies.

AN - 1551022712; 25076055 AB - Dichlorodiphenyltrichloroethane (DDT) has been used extensively to control malaria, typhus, body lice and bubonic plague worldwide, until countries began restricting its use in the 1970s. Its use in malaria control continues in some countries according to recommendation by the World Health Organization. Individuals exposed to elevated levels of DDT and its metabolite dichlorodiphenyldichloroethylene (DDE) have an increased prevalence of diabetes and insulin resistance. Here we hypothesize that perinatal exposure to DDT disrupts metabolic programming leading to impaired metabolism in adult offspring. To test this, we administered DDT to C57BL/6J mice from gestational day 11.5 to postnatal day 5 and studied their metabolic phenotype at several ages up to nine months. Perinatal DDT exposure reduced core body temperature, impaired cold tolerance, decreased energy expenditure, and produced a transient early-life increase in body fat in female offspring. When challenged with a high fat diet for 12 weeks in adulthood, female offspring perinatally exposed to DDT developed glucose intolerance, hyperinsulinemia, dyslipidemia, and altered bile acid metabolism. Perinatal DDT exposure combined with high fat feeding in adulthood further impaired thermogenesis as evidenced by reductions in core temperature and in the expression of numerous RNA that promote thermogenesis and substrate utilization in the brown adipose tissue of adult female mice. These observations suggest that perinatal DDT exposure impairs thermogenesis and the metabolism of carbohydrates and lipids which may increase susceptibility to the metabolic syndrome in adult female offspring.

Between December 2012 and April 2013, bats were observed flying during daylight hours throughout the Great Smoky Mountains National Park. Although some bats displayed typical foraging and drinking behavior, others appeared sick or incapable of flying, some were flying erratically, and one collided with a hiker. These observations tended to be reported on warmer-than-average days. Nine bats were collected and tested negative for rabies; 6 that were tested for White-nose Syndrome (WNS) via histology were all diagnosed as WNS positive. An additional 6 bats that were not tested for rabies were also WNS positive. We hypothesize bats were becoming increasingly active and emerging from hibernacula due to WNS.

Understanding dispersal of adults between orchards is important to improving management options. Laboratory flight behavior of unmated navel orangeworm of ages 1, 2, 3, 5, and 7 d posteclosion was examined using flight mills. As a group, females flew farther and longer than males, but the differences were not statistically significant. Flight speed did not differ between sexes. Flight duration and distance did not differ with age, except that 7-d-old adults performed worse for these parameters than did 1- and 2-d-old adults. Females began their flights approximately 1.5 h after the onset of dusk, and approximately 1.5 h earlier in the night than males. Flight capacity and propensity were substantial for both sexes and all age classes tested. At least 20% of adults (except 7-d-old males) made a continuous flight greater than or equal to 5.5 h, and median total distances flown during the 10.5-h night ranged from 7 to 15 km depending on age class. Thus navel orangeworm flight mill performance was greater than that of most pests tested from the families Pyralidae and Tortricidae. Surface area and length of forewings and hindwings were greater in females than males, but had little effect on flight performance. The results are generally consistent with field observations of navel orangeworm dispersal, but it will be important to characterize the effects of mating on flight, and flight on fecundity.

Knowledge of arthropod natural enemies and their impact on soybean aphid is critical for developing biological control as a management tool. Soybean is a major field crop in South Dakota, but information about its natural enemies and their impact on soybean aphid is lacking. Thus, this study was conducted in field plots in eastern South Dakota during July and August of 2004 and 2005 to characterize foliar-dwelling, arthropod natural enemies of soybean aphid, and it used exclusion techniques to determine impact of natural enemies and ants (Hymenoptera: Formicidae) on soybean aphid densities. In open field plots, weekly soybean aphid densities reached a plateau of several hundred aphids per plant in 2004, and peaked at roughly 400 aphids per plant in 2005. Despite these densities, a relatively high frequency of aphid-infested plants lacked arthropod natural enemies. Lady beetles (Coleoptera: Coccinellidae) were most abundant, peaking at 90 and 52% of all natural enemies sampled in respective years, and Harmonia axyridis Pallas was the most abundant lady beetle. Green lacewings (Neuroptera: Chrysopidae) were abundant in 2005, due mainly to large numbers of their eggs. Abundances of arachnids and coccinellid larvae correlated with soybean aphid densities each year, and chrysopid egg abundance was correlated with aphid density in 2005. Three-week cage treatments of artificially infested soybean plants in 2004 showed that noncaged plants had fewer soybean aphids than caged plants, but abundance of soybean aphid did not differ among open cages and ones that provided partial or total exclusion of natural enemies. In 2005, plants within open cages had fewer soybean aphids than those within cages that excluded natural enemies, and aphid density on open-cage plants did not differ from that on noncaged plants and those accessible by small predators. In a separate 3-yr experiment, exclusion of ants from soybean plants did not lead to differences in soybean aphid density compared with ant-accessible plants. Overall, these results suggest that the soybean aphid natural enemy guild is unsaturated and could be enhanced to improve biological control of soybean aphid in South Dakota.

The leaf beetle Diorhabda elongata (Brulle) from Crete, imported to the United States for the control of saltcedar (Tamarix spp., Tamaricaceae), showed a low but variable ovipositional response to nontarget Frankenia spp. (Frankeniaceae) in previous laboratory tests conducted in small cages, where up to 11.4% of eggs were laid on these native plants. Results from field tests presented in this article show that no eggs were laid on Frankenia palmeri S. Watson and significantly more eggs were always laid on Tamarix ramosissima Ledebour than Frankenia salina (Molina) I. M. Johnston. Furthermore, the ovipositional response to F. salina was substantially lower than that recorded in laboratory tests. The percent of eggs laid on F. salina in field tests was 3.7 in a paired choice cage test, 4.3 in a multiple choice cage test, and 2.5 in a multiple choice open field test, suggesting that the true acceptance rate of the nontarget by D. elongata in the field will be lower than laboratory tests predicted. However, some damage was caused to F. salina by adult and larval feeding in the field, although this occurred only at the very end of the open field test, when D. elongata densities were extremely high, and all of the surrounding saltcedar had been totally defoliated. Scientific representatives from various stakeholder organizations (state, county, university, and environmental groups) viewed the open field test when in progress and reviewed the final results before advising State regulatory agencies on beetle redistribution. These test results, and the open review process, led regulators to conclude that redistribution of D. elongata in California was warranted owing to its significant ability to defoliate saltcedar, and its low rate of feeding on nontarget Frankenia spp. The introduction of D. elongata provides an interesting case study for risk assessment of a potentially efficacious weed biocontrol agent that may also be capable of using nontarget native plants.

AN - 1535627272; 24914553 AB - Shiga toxin-producing E. coli (STEC) are a group of common and potentially deadly intestinal pathogens expressing Shiga toxin (Stx) as a primary virulence factor. Of the two types of Stx, Stx2 is responsible for more severe symptoms during infection, while Stx1 is almost identical to the Shiga toxin from Shigella dysenteriae, a ubiquitous pathogen in developing countries. Although antibodies against Stx1 have been reported, few have reached the affinity needed for assembling highly sensitive immunoassays. Sensitive and affordable immunoassays for Stx1 and Stx2 could help improve detection of STEC in livestock, food, the environment, and in clinical samples resulting in improved food safety and human health. Three new monoclonal antibodies (mAbs) against the B subunit of Stx1 were generated using recombinant toxoid Stx1E167Q and hybridoma technology. These new mAbs recognize all subtypes of Stx1, but do not cross-react with any subtype of Stx2. In addition, they exhibited the ability to neutralize Stx1 toxicity in Vero cell assays. An optimized sandwich ELISA using of a pair of these mAbs had a limit of detection of 8.7 pg/mL, which is superior to any existing assay of this kind. Using one of these Stx1 mAbs in concert with Stx2 mAbs, the presence of hybrid Stx1/Stx2 toxin in the culture media of STEC strains that express both Stx1 and Stx2 was demonstrated. These new mAbs provide a mix of availability, utility, versatility, and most importantly, increased sensitivity for detection of Stx1. There are numerous potential applications for these mAbs, including low-cost detection assays and therapeutic use. Analysis of hybrid Stx1/2 could provide new insights on the structure, activity, and cellular targets of Shiga toxins.

Physiological metrics for detecting stressed trees with enhanced vulnerability prior to bark beetle attacks remain elusive. Ethanol, water, monoterpene concentrations, and composition were examined in the phloem and sapwood of drought-stressed Aleppo pine (Pinus halepensis Mill.) freshly attacked by mature Mediterranean pine shoot beetles (Tomicus destruens (Wollaston, 1865)) and in neighboring unattacked trees. The attacked trees were more water-stressed and contained, on average, 2.1 and 2.4 times more ethanol in the phloem and sapwood, respectively, than the neighboring attack-free trees. This response is consistent with the known attraction of T.destruens to ethanol. Most monoterpene concentrations in the phloem, but not sapwood, were greater in tissues of attacked trees, whereas compositional differences were minor between the two tree groups for both tissues. Tissue water content explained much of the variation in phloem monoterpene concentrations, which increased as water in the phloem declined, suggesting that higher constitutive quantities existed in the more stressed trees prior to the attacks. Monoterpenes may have contributed to host tree selection by T.destruens, but their potential influence is considered less important than that of ethanol based on beetle responses to these compounds in previous trapping studies. This is the first report of elevated ethanol concentrations in tissues of trees experiencing natural drought stress and suggests that ethanol measurements in severely water-stressed trees may allow early detection of those most vulnerable to bark beetle attack.Original Abstract: La mortalite chez les arbres due a la secheresse causee par la temperature se manifeste dans les forets partout dans le monde, souvent conjointement avec les epidemies de scolytes, lorsque la quantite de carbone alloue aux mecanismes de defense diminue. Les metriques physiologiques qui permettraient de detecter les arbres stresses les plus vulnerables avant qu'ils soient attaques par les scolytes demeurent nebuleuses. La composition et les concentrations en ethanol, eau et monoterpenes ont ete examinees dans le phloeme et le bois d'aubier de pins d'Alep (Pinus halepensis Mill.) stresses par la secheresse qui venaient juste de subir l'attaque d'hylesines du pin (Tomicus destruens Wollaston, 1865) matures en Mediterranee et d'arbres voisins qui n'avaient pas ete attaques. Le stress hydrique etait plus prononce chez les arbres attaques qui contenaient en moyenne respectivement 2,1 et 2,4 fois plus d'ethanol dans le phloeme et le bois d'aubier que les arbres voisins qui n'avaient pas ete attaques. Cette reaction est coherente avec l'attraction qu'exerce l'ethanol sur T.destruens. La concentration de la plupart des monoterpenes dans le phloeme, mais pas dans le bois d'aubier, etait plus elevee dans les tissus des arbres attaques tandis que les differences de composition en monoterpenes entre les deux groupes d'arbres etaient mineures quel que soit le tissu. La teneur en eau des tissus expliquait la majeure partie de la variation de la concentration des monoterpenes presents dans le phloeme laquelle augmentait a mesure que la teneur en eau du phloeme diminuait, ce qui indique qu'une plus grande quantite de monoterpenes constitutifs etaient presents dans les arbres plus stresses avant les attaques. Les monoterpenes peuvent avoir contribue au choix des arbres hotes par T.destruens mais on considere que leur influence potentielle est moins importante que celle de l'ethanol sur la base des reactions de l'insecte a ces composes dans le cadre de precedentes etudes de piegeage. Il s'agit de la premiere mention de concentrations elevees d'ethanol dans les tissus des arbres qui subissent un stress du a une secheresse naturelle. Ces resultats indiquent qu'il serait peut-etre possible de detecter precocement les individus les plus vulnerables a une attaque de scolytes en mesurant la quantite d'ethanol presente chez les arbres soumis a un stress hydrique severe.

AN - 1534831877; 20046672 AB - In parts of central Oregon, coarse-textured pumice substrates limit forest composition to low-density lodgepole pine (Pinus contorta Douglas ex Loudon var. latifolia Engelm. ex S. Watson) with scattered ponderosa pine (Pinus ponderosa Lawson & C. Lawson) and a shrub understory dominated by antelope bitterbrush (Purshia tridentata (Pursh) DC.). We reconstructed the historical fire regime from tree rings and simulated fire behavior over 783 ha of this forest type. For centuries (1650-1900), extensive mixed-severity fires occurred every 26 to 82 years, creating a multi-aged forest and shrub mosaic. Simulation modeling suggests that the historical mix of surface and passive crown fire were primarily driven by shrub biomass and wind speed. However, a century of fire exclusion has reduced the potential for the high-severity patches of fire that were common historically, likely by reducing bitterbrush cover, the primary ladder fuel. This reduced shrub cover is likely to persist until fire or insects create new canopy gaps. Crown fire potential may increase even with current fuel loadings if the climate predicted for midcentury lowers fuel moistures, but only under rare extreme winds. This study expands our emerging understanding of complexity in the disturbance dynamics of lodgepole pine across its broad North American range.Original Abstract: Dans certaines parties du centre de l'Oregon, la foret est seulement composee de pin tordu latifolie (Pinus contorta Douglas ex Loudon var. latifolia Engelm. ex S. Watson) a faible densite avec la presence sporadique du pin ponderosa (Pinusponderosa Lawson & C. Lawson) et d'un sous-etage domine par la purshie tridentee (Purshia tridentata (Pursh) DC.) a cause de substrats a texture grossiere composes de pierre ponce. Nous avons reconstitue le regime des feux passe a partir des cernes annuels et nous avons simule le comportement du feu sur 783 ha de ce type de foret. Pendant des siecles (1650-1900), de vastes incendies d'intensite mixte sont survenus a tous les 26-82 ans, creant une foret inequienne et une mosaique d'arbustes. Les simulations indiquent que la biomasse des arbustes et la vitesse du vent etaient les principaux facteurs responsables du melange historique de feux de surface et de feux de cime intermittents. Cependant, l'exclusion du feu depuis un siecle a reduit la possibilite que des parcelles de foret soient brulees par des feux de severite elevee, frequents dans le passe, probablement en reduisant le couvert de purshie tridentee, le principal combustible etage. Ce faible couvert d'arbuste persistera probablement jusqu'a ce que le feu ou les insectes creent de nouvelles trouees dans le couvert forestier. La possibilite qu'il y ait des feux de cime pourrait augmenter, meme avec les charges actuelles de combustibles, si le climat qui est predit pour le milieu du siecle reduit la teneur en humidite des combustibles et a condition qu'il y ait de forts vents, ce qui est rare. Cette etude enrichit les connaissances recemment acquises au sujet de la complexite de la dynamique des perturbations chez le pin tordu, partout dans son aire de repartition a travers l'Amerique du Nord.

Methods: We measured the self-esteem profile using the Self-Perception Profile for Children among 910 minority children at 17 Houston community centers. Results: Weight status had no effect on any of the self-esteem scores among the minority children (P greater than or equal to 0.21). Black children had higher scholastic competence than Hispanic children (P = 0.05). Social acceptance was not affected by age, gender, and race/ethnicity (P greater than or equal to 0.13). Significant age x gender (P = 0.006) and race x gender (P = 0.005) interactions were detected on athletic competence. The younger boys had higher athletic competence than the younger and older girls (P less than or equal to 0.01). The older boys had higher athletic competence than the older girls (P = 0.008) but their scores were not different from those of the younger girls (P = 0.07). Within each race/ethnicity group, boys had higher athletic competence than girls (P less than or equal to 0.03). Black boys had higher athletic competence than Hispanic girls (P = 0.007) but their scores were not different from those of the Hispanic boys (P = 0.08). Age and gender had no effect on physical appearance but black children had higher scores than Hispanic children (P = 0.05). Behavioral conduct was not affected by age, gender, or race/ethnicity (P greater than or equal to 0.11). There was an age x gender interaction on global self-worth (P = 0.02) with boys having similar scores regardless of ages (P = 0.40) or ethnicity (P = 0.98). However, boys from both age groups had higher global self-worth than the older girls (P less than or equal to 0.04) but their scores were not different from those of the younger girls (P greater than or equal to 0.07). Conclusions: For the first time, we documented that being normal weight did not necessarily guarantee positive self-esteem among minority children. Their self-esteem scores were similar to those found among children who were diagnosed with obesity and obesity-related co-morbidities and lower than those reported among normal-weight white children. Therefore, activities to promote self-esteem are important when working with underserved minority children in order to promote a healthy lifestyle.

The purpose of this synthesis was to provide information to forest managers to help make decisions about conservation assessments and strategies for rich cove forests in the southern Appalachians. An important finding is that no single study or data set can provide conclusive evidence or clear management strategies. However, an overriding conclusion is that the magnitude of impact and the management actions necessary to restore herbaceous communities are directly proportional to the severity of disturbance, current condition (e.g., presence of Rhododendron), site heterogeneity, and historical land use (e.g., agricultural activity). These factors plus a host of other stressors (e.g., climate variability, air pollution, invasives) are likely to have a strong influence on the highly variable patterns observed when comparing herbaceous diversity of 'old-growth' or uncut forests to human disturbed forests (e.g., cutting, air pollution, conversion, invasive plants or insects). Results from this review reinforce our premise that factors controlling herbaceous species presence and abundance are highly complex, thus broad generalizations about the impacts of a single factor such as logging should be interpreted with caution. Of the stressors known to affect forest trees (e.g., pests and pathogens, acidic deposition, air pollution, drought, and wind), little to no information exists on how these same stressors will affect herbaceous plants. A limited number of studies have examined the demography or physiology of forest herbs, particularly across all life stages. While the demography of a few genera have been studied (e.g., Hexastylis, Asarum, Trillium, Arisaema, Goodyera, Hepatica), little to no information exists for the majority of woodland herbs. Species identity is important when considering management of rich cove forests. Diversity may increase following canopy disturbances that favor recruitment of early-seral herbaceous species; therefore, simple indices of diversity (H', S, and E) are not the best measure of recovery in mesophytic rich coves, particularly where shade-adapted 'rich-cove indicator' species have been replaced by these species. Species-specific life histories and the influence of prevailing site conditions are important lines of research for understanding recovery and sustainability of mesophytic rich cove forests.

Sample plots centered on focal California black oaks (Quercus kelloggii) were established to evaluate oak and neighboring tree and shrub recovery across a gradient of fire severity in the southern Cascade Range, USA. Shrub and oak resprouting was strongest around focal oaks where conifer mortality was greatest. Linear modeling revealed negative relationships between California black oak sprout height or basal area and residual overstory tree survival, primarily white fir (Abies concolor). The two dominant competing species, California black oak and white fir, showed opposite responses to fire severity. Sprouting California black oak and associated shrubs dominated in severely burned areas, while surviving, non-sprouting white fir maintained dominance by its height advantage and shading effects in areas that burned with low fire severity. Our results indicate that high-severity fire promotes persistence and restoration of ecosystems containing resprouting species, such as California black oak, that are increasingly rare due to widespread fire exclusion in landscapes that historically experienced more frequent fire. We present a conceptual model based on our results and supported by a synthesis of postfire resprouting dynamics literature. Our results and conceptual model help illuminate long-term postfire vegetation responses and the potential ability of fire to catalyze formation of alternate vegetation community structures that may not be apparent in studies that evaluate postfire effects at shorter time-since-fire intervals or at coarser scales.

For adaptation to the local site, local plant materials have often been assumed to be best. While local adaptation has long been used as an argument for the exclusive use of local plant materials, recent meta-analysis results indicate that general adaptation across a variety of environments can be just as important as local adaptation. Here I argue that "ecologically appropriate" plant materials with enhanced general adaptation and effective expression of functional traits, including establishment and persistence, will become increasingly important as degradation increases. This approach will be useful for generalist "workhorse" native species that are common, widespread, and can be readily propagated under cultivation.

Despite caveats to the contrary, an implicit assumption continues to emerge of climatic stationarity, and, by corollary, that presettlement centuries provide an appropriate reference period. This is examined from the perspective of historic climate change and ecosystem response. As a means of developing reference prescriptions and management targets, HRV is generally inappropriate, although if historic periods are used for reconstruction that have coarse resemblance to present or projected future climates, such as the Medieval Climate Anomaly or middle Holocene rather than the presettlement centuries, these might be defensible. In cases of reclamation of severely degraded ecosystems, HRV prescriptions developed from analogous climate periods could provide coarse guides. In most situations, however, historic reconstructions are best used to improve understanding of ecological response to a wide range of forcing factors, and thereby to inform (rather than prescribe) management strategies. Such historically informed approaches are likely more effective than an HRV approach under future changing climate regimes for managing and restoring ecosystem function and for assisting transitions to new ecosystem states.

This approach, called functional restoration, uses indicators of ecosystem health such as mortality, regeneration, reproduction, and productivity, as well as surrogates such as structural diversity, age class distribution, and species diversity, to characterize ecosystem health. Although restoring ecosystem health is the primary emphasis, manipulating species composition and forest structure are the means for accomplishing functional restoration. Managers have experience in measuring most indicators of ecosystem health and, for the most part, cost effective methods for measuring them exist. Instead of using the composition and structure from the historic record as the benchmark, ecosystem health as measured from the time of treatment-i.e., the initial conditions, and changes in these conditions with time-becomes the measure of success. By applying this approach, restoration becomes an investment in the future.

Clearly described and quantitative endpoints and intermediary targets are needed to manage restoration of ecosystem structure, composition, function, and production. Selecting indicators of key ecosystem attributes that are linked to endpoint and target condition, function, sustainability, health, integrity, resilience, and production is important to monitoring restoration success. Indicators are used to track ecosystem trajectory, assess progress toward achieving endpoints and targets, adapt management, and communicate with external publics. Reference sites can be used to help set endpoints and targets with caution. Other science-based ecosystem models or management tools are available to help quantify intermediate targets and endpoints. Continued work to better understand historic ecosystem conditions is fundamental to assessing change, extent of damage, and restoration potential. A hierarchy of forest plans from regional and landscape to site specific are useful for defining endpoints, targets, and indicators at appropriate ecological scales; and to consider populations, ecosystem function, and socioeconomic factors that operate at a variety of scales.

The aim of this study was to examine the associations of snacking patterns with nutrient intake, diet quality, and a selection of CVRF in adults participating in the 2001-2008 National Health and Nutrition Examination Survey. Methods: 24-hour dietary recalls were used to determine intake and cluster analysis was used to identify the snacking patterns. Height and weight were obtained and the health indices that were evaluated included diastolic and systolic blood pressure, high density lipoprotein-cholesterol, low density lipoprotein cholesterol, triacylglycerides, blood glucose, and insulin. Results: The sample was participants (n = 18,988) 19+ years (50% males; 11% African-Americans; 72% white, 12% Hispanic-Americans, and 5% other). Cluster analyses generated 12 distinct snacking patterns, explaining 61% of the variance in snacking. Comparisons of snacking patterns were made to the no snack pattern. It was found that miscellaneous snacks constituted the most common snacking pattern (17%) followed by cakes/cookies/pastries (12%) and sweets (9%). Most snacking patterns were associated with higher energy intakes. Snacking patterns cakes/cookies/pastries, vegetables/legumes, crackers/salty snacks, other grains and whole fruit were associated with lower intakes of saturated fatty acids. Added sugars intakes were higher in the cakes/cookies/pastries, sweets, milk desserts, and soft drinks patterns. Five snack patterns (cakes/cookies/pastries, sweets, vegetable/legumes, milk desserts, soft drinks) were associated with lower sodium intakes. Several snack patterns were associated with higher intakes of potassium, calcium, fiber, vitamin A, and magnesium. Five snacking patterns (miscellaneous snacks; vegetables/legumes; crackers/salty snacks; other grains; and whole fruit) were associated with better diet quality scores. Alcohol was associated with a lower body mass index and milk desserts were associated with a lower waist circumference. No snack patterns were associated with other CVRF studied. Conclusions: Overall, several snacking patterns were associated with better diet quality than those consuming no snacks. Yet, the majority of the snacking patterns were not associated with CVRF. Education is needed to improve snacking patterns in terms of nutrients to limit in the diet along with more nutrient-dense foods to be included in snacks.

However, random sampling of rural populations in developing nations can be challenged by incomplete enumeration of the base population. Methods: We describe a stratified random sampling method using geographical information system (GIS) software and global positioning system (GPS) technology for application in a health survey in a rural region of Guatemala, as well as a qualitative study of the enumeration process. Results: This method offers an alternative sampling technique that could reduce opportunities for bias in household selection compared to cluster methods. However, its use is subject to issues surrounding survey preparation, technological limitations and in-the-field household selection. Application of this method in remote areas will raise challenges surrounding the boundary delineation process, use and translation of satellite imagery between GIS and GPS, and household selection at each survey point in varying field conditions. This method favors household selection in denser urban areas and in new residential developments. Conclusions: Random spatial sampling methodology can be used to survey a random sample of population in a remote region of a developing nation. Although this method should be further validated and compared with more established methods to determine its utility in social survey applications, it shows promise for use in developing nations with resource-challenged environments where detailed geographic and human census data are less available.

GROWTH AND MINERAL UPTAKE FROM LEAD-ARSENATE CONTAMINATED ORCHARD SOILS AN - 1516753419; 19038779 AB - Growth and mineral uptake was studied in stinging nettle (Urtica dioica L.) grown on lead-arsenate contaminated orchard soils. Six soil samples including a non-orchard control were used. Uniform U. dioica seedlings were transplanted into pots arranged in a completely randomized design and raised under uniform greenhouse conditions. Shoots were harvested at day 26, and shoot (harvest 2) and root portions 50 days after transplanting. All samples were oven dried, weighed, and processed for mineral analysis. Elevated arsenic levels in soil did not significantly affect nettle growth except at the highest concentration of 163 mg kg super(-1). There was arsenic bio-concentration in U. dioica roots and high levels of arsenic and lead in both below- and aboveground tissues. Stinging nettle is a plant of economic importance harvested for food and medicine. Our results show that humans can be exposed to toxic levels of arsenic and lead through contaminated nettle products.

These alterations have led to understories dominated by species simultaneously browse tolerant, shade tolerant, and fire sensitive leading to difficulties in the regeneration of oak species (Quercus spp.) in some areas. We evaluated how three key processes - understory fire, canopy gaps, and browsing - influenced tree species in east central West Virginia. We were particularly interested in the response of oak species because they are the dominant overstory species and of maple species (Acer spp.), black birch (Betula lenta L.), and yellow-poplar (Liriodendron tulipifera L.) as these are likely to replace the current forest. Single-process effects were significant and significant interactions among processes were numerous. In general, fire caused significant reductions of seedlings and saplings of red maple (Acer rubrum L.) and striped maple (Acer pensylvanicum L.) and increased the seedlings of black birch and yellow-poplar. Canopy gaps increased the abundance of black birch and yellow-poplar seedlings and saplings. Gaps and fire together caused an increase in the relative abundance of yellow-poplar. Excluding browsers and creating canopy gaps together nearly doubled oak sapling importance values versus either treatment alone; however, oak importance values remained low. Given the significant interactions of browse control with the other two processes, browse control should be considered when planning oak regeneration treatments such as canopy gaps or prescribed fire.Original Abstract: Les forets actuelles se sont developpees sous des conditions differentes de celles des forets d'origine, soit une densite plus elevee de cerfs, une frequence de feu plus faible et un couvert forestier plus dense comportant de plus petites trouees. Ces modifications ont produit des sous-etages domines par des especes simultanement tolerantes au broutement, tolerantes a l'ombre et sensibles au feu, ce qui a cause des problemes de regeneration des especes de chene a certains endroits. Nous avons determine de quelle facon trois processus cles : les feux en sous-etage, les trouees dans le couvert forestier et le broutement, ont influence la presence d'especes d'arbre dans le centre-est de la Virginie occidentale. Nous etions particulierement interesses par la reaction des especes de chene, parce qu'elles sont les especes dominantes du couvert, et par les erables, le bouleau noir et le tulipier de Virginie, parce que ces especes remplaceront probablement les especes dominantes actuelles. Les effets simples des processus etaient significatifs et les interactions significatives entre les processus etaient nombreuses. En general, le feu a significativement reduit le nombre de semis et de gaules d'erables rouge et de Pennsylvanie, et a augmente le nombre de semis de bouleau noir et de tulipier de Virginie. Les trouees dans le couvert forestier ont cause une augmentation de l'abondance des semis et des gaules de bouleau noir et de tulipier de Virginie. L'effet combine des trouees et du feu a cause une augmentation de l'abondance relative du tulipier de Virginie. L'exclusion du broutement conjuguee a la creation de trouees dans le couvert forestier a presque fait doubler la valeur d'importance (VI) des gaules de chene par rapport a l'effet de ces deux traitements pris separement. Toutefois, la VI du chene est demeuree faible. Etant donne les interactions significatives entre la maitrise du broutement et les deux autres processus, la maitrise du broutement devrait etre consideree lors de la planification des traitements de regeneration des chenes tels que les trouees dans le couvert forestier et le brulage dirige.

We also characterize total biomass of soil microorganisms and the most probable number of bacteria along a topographic gradient within each bioclimatic subzone to evaluate whether differences in topography lead to differences in microbial dynamics at a smaller scale. We found total microbial biomass C, the most probable number of heterotrophic bacteria, and fungal genera vary along this bioclimatic gradient. Microbial biomass C decreased with increasing latitude. Overall, microbial biomass C, MPN and the number of fungal isolates were higher in AVS than in PGFs. The effects which topographic position had on microbial biomass C varied across the bioclimatic gradient as there was no effect of topographic position in Isachsen (subzone A) and Mould Bay (subzone B), when compared to Green Cabin (subzone C, warmer site).There was no effect of topographic position on MPN counts at Mould Bay and Green Cabin. However, in Isachsen, MPN counts were highest in the wet topographic position as compared to the mesic and dry. In conclusion, PGFs seem to decouple the effect climate that might have on the total biomass of soil microorganisms along the bioclimatic gradient; and influence gets ameliorated as latitude increases. Similarly, the effect of topography on the total microbial biomass is significant at the warmest bioclimatic zone of the gradient. Thus, climate and topographic effects on total microbial biomass increase with warmer climate.

In 2010 and 2011, we compared 1) green canopy traps, 2) purple canopy traps, 3) green double-decker traps, and 4) purple double-decker traps in sites representing a range of A. planipennis infestation levels. Traps were baited with cis-3-hexenol in both years, plus an 80:20 mixture of Manuka and Phoebe oil (2010) or Manuka oil alone (2011). Condition of trees bearing canopy traps, A. planipennis infestation level of trees in the vicinity of traps, and number of A. planipennis captured per trap differed among sites in both years. Overall in both years, more females, males, and beetles of both sexes were captured on double-decker traps than canopy traps, and more beetles of both sexes (2010) or females (2011) were captured on purple traps than green traps. In 2010, detection rates were higher for purple (100%) and green double-decker traps (100%) than for purple (82%) or green canopy traps (64%) at sites with very low to low A. planipennis infestation levels. Captures of A. planipennis on canopy traps consistently increased with the infestation level of the canopy trap-bearing trees. Differences among trap types were most pronounced at sites with low A. planipennis densities, where more beetles were captured on purple double-decker traps than on green canopy traps in both years.

As a cosmopolitan pest of cotton and other high-value cash crops, confirmation of feeding by first instars may ultimately influence the knowledge on biology and management strategies for this pest. To determine whether first instars feed, newly hatched nymphs were provided sterile green beans (control) or beans infected with a rifam-picin-resistant marked bacterial pathogen (Pantoea agglomerans (Ewing and Fife)) of cotton. Insects were exposed to beans for 2 d, and feeding was confirmed based on detection of marked bacteria ingested by the insect. Normal bacterial flora was detected in all insects; however, control insects did not possess the marked bacteria. Of the first instars surviving on infected beans, approximately 65% possessed the marked bacteria internally. Furthermore, the frequency of insects with marked bacteria was higher in insects collected directly from the bean surface than those that were off the bean at time of collection. Densities of innate and marked bacteria were comparable (both ranging from 101 to 103), suggesting that the marked bacteria did not exclude preexisting bacterial flora. Marked bacteria were also detected in a subset of second instars, indicating marked bacteria were retained through the molting process after ingesting bacteria as first instars. Our findings conclusively demonstrate feeding by first instars and redefine the long-held perspective of nonfeeding by first instars. These findings may necessitate changes to crop protection strategies against feeding and vectoring of plant pathogens by N. viridula.

The United States Department of Agriculture-Natural Resources Conservation Service (USDA-NRCS) employs a 1:1 suspension of soil in water (pH1:1 (sub W) ), and a 1:2 suspension of soil in (sub CaCl2) (0.01M) (pH1:2 (sub CaCl2) ) for routine pH analysis (Soil Survey Staff, 2009). The objective of this study was to determine the most efficient way to convert these pH values to the GlobalSoilMap standard. For this analysis, 563 soil samples from the USDA-NRCS-National Soil Survey Center (NSSC) soil archive, which had been previously analysed for pH1:1 (sub W) and pH1:2 (sub CaCl2) , were selected for determination of pH1:5 (sub W) , pH1:5 (sub CaCl2) and electrical conductivity (EC) in 1:2 suspension of soil in water (EC 1:2 (sub W) ). The samples represented 11 soil orders, 8 mineralogy classes, 5 family particle size classes, 4 genetic master horizons, and 7 depth intervals. For each category, 25-30 samples were selected to represent a comprehensive pH range. Regression analysis showed strong and significant relationships (R (super 2) >0.92) between pH methods across all categories. The simple linear regression equation, pH1:5 (sub W) =-0.51+1.06 pH1:1 (sub W) , had an RMSE=0.44 pH units. Smoothing spline, did not significantly improve pH1:5 (sub W) predictions, nor did the incorporation of EC. Genetic horizons and soil depth intervals did not have a significant effect on pH1:5 (sub W) . The linear regression models for predicting pH1:5 (sub W) using pH1:1 (sub W) or pH1:2 (sub CaCl2) as predictors emerged as the best candidates for a standard pedotransfer function.

However, fire exclusion has reduced frequency of fire and area burned in many dry forest types, which may affect vegetation structure and composition, and potential fire behavior. In forests of the western U.S., these effects pose a challenge for fire and land managers who seek to restore the ecological process of fire to ecosystems. Recent research suggests that landscapes with unaltered fire regimes are more "self-regulating" than those that have experienced fire-regime shifts; in self-regulating systems, fire size and severity are moderated by the effect of previous fire. To determine if burn severity is moderated in areas that recently burned, we analyzed 117 wildland fires in 2 wilderness areas in the western U.S. that have experienced substantial recent fire activity. Burn severity was measured using a Landsat satellite-based metric at a 30-m resolution. We evaluated (1) whether pixels that burned at least twice since 1984 experienced lower burn severity than pixels that burned once, (2) the relationship between burn severity and fire history, pre-fire vegetation, and topography, and (3) how the moderating effect of a previous fire decays with time. Results show burn severity is significantly lower in areas that have recently burned compared to areas that have not. This effect is still evident at around 22 years between wildland fire events. Results further indicate that burn severity generally increases with time since and severity of previous wildfire. These findings may assist land managers to anticipate the consequences of allowing fires to burn and provide rationale for using wildfire as a "fuel treatment".

Low levels of physical activity (PA) are a risk factor for obesity. Characterizing what Latino parents do to encourage or discourage their preschooler to be physically active can help inform interventions to increase their PA. The objective was therefore to develop and assess the psychometrics of a new instrument: the Preschooler Physical Activity Parenting Practices (PPAPP) among a Latino sample, to assess parenting practices used to encourage or discourage PA among preschool-aged children. Methods: Cross-sectional study of 240 Latino parents who reported the frequency of using PA parenting practices. 95% of respondents were mothers; 42% had more than a high school education. Child mean age was 4.5 ( plus or minus 0.9) years (52% male). Test-retest reliability was assessed in 20%, 2 weeks later. We assessed the fit of a priori models using Confirmatory factor analyses (CFA). In a separate sub-sample (35%), preschool-aged children wore accelerometers to assess associations with their PA and PPAPP subscales. Results: The a-priori models showed poor fit to the data. A modified factor structure for encouraging PPAPP had one multiple-item scale: engagement (15 items), and two single-items (have outdoor toys; not enroll in sport-reverse coded). The final factor structure for discouraging PPAPP had 4 subscales: promote inactive transport (3 items), promote screen time (3 items), psychological control (4 items) and restricting for safety (4 items). Test-retest reliability (ICC) for the two scales ranged from 0.56-0.85. Cronbach's alphas ranged from 0.5-0.9. Several sub-factors correlated in the expected direction with children's objectively measured PA. Conclusion: The final models for encouraging and discouraging PPAPP had moderate to good fit, with moderate to excellent test-retest reliabilities. The PPAPP should be further evaluated to better assess its associations with children's PA and offers a new tool for measuring PPAPP among Latino families with preschool-aged children.

Split ponds require large water volumes circulated between the two basins (10,000-20,000 gal/min for 5-10-acre ponds) to remove fish waste and provide oxygenated water to the fish. Farmers producing ictalurid catfish in the USA have rapidly adopted this new technology to improve production efficiency. The original split-pond design used large, slow-rotating paddlewheels to circulate water; in this study, we evaluated paddlewheel aerators as pumps for split ponds. Pumping performance was evaluated at rotational speeds of 25-66 rotations/min and paddle submergence depths of 4.0, 6.8, and 9.5 in. Water flow rates ranged from 8,240 to 25,069 gal/min. Flows increased with increasing rotational speed and paddle submergence depth. Power input varied directly with flow rate and ranged from 1.08 to 8.28 hp. Water discharge per unit power input (i.e., pumping efficiency) ranged from 3,026 to 10,824 gal.min super(-1).hp super(-1); pumping efficiency decreased as water flow rate increased and as paddle submergence depth decreased. Placement of the paddlewheel at the channel inlet (with water being pushed through the channel) produced flow rates three times greater than placement at the outlet (with water being pulled through the channel). Our results show that commercial paddlewheel aerators can be modified, operated, and located to provide the water flows needed in commercial-sized split ponds. Although they are more expensive to operate than slow-rotating paddlewheels (which are specifically designed as water pumps), paddlewheel aerators offer the advantages of lower investment cost, greater availability, and easy maintenance. Long-term studies are underway to compare operational issues and costs associated with the use of various pump types, including paddlewheel aerators, in split-pond aquaculture.

We examined male reproductive competition together with precopulation and copulation durations, female longevity, and fecundity in the northern corn rootworm in relation to the body size of males and females that were combined for mating. Longevity and fecundity were determined for individually caged, mated females. Of the females in 108 combinations of two males and one female, 35 chose not to mate. Of the females in the 73 combinations that resulted in copulation, 38 were small and 35 were large. The proportions of large and small males that mated did not vary significantly with female size, but large males were more than twice as likely as small males to mate. The precopulation duration did not vary with either male or female size, and no interaction occurred between male and female size for either the precopulation or copulation duration. However, both male and female size affected the duration of copulation, with small males copulating longer than large males and large females copulating longer than small females.Nofemale longevity or egg number differences occurredamongthe body size categories of the mating pairs. The implications of the results for insect resistance management are discussed, considering that the evolution of resistance to certain management strategies, such as resistance to the use of insecticides or of Bt maize, may be accompanied by changes in body size.

This pathogen is vectored by the potato/ tomato psyllid Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), but little is known about the interactions between B. cockerelli and 'Ca. Liberibacter solanacearum.' Fluorescence in situ hybridization was used to assess the incidence of 'Ca. Liberibacter solanacearum' in the hemolymph, bacteriomes, alimentary canals, and salivary glands of B. cockerelli. Liberibacter was observed in 66% of alimentary canals, 39% of salivary glands, and 40% of bacteriomes dissected from adult psyllids. Compared with adults, the organs of fifth instars appeared less likely to harbor Liberibacter, which was observed in 52% of alimentary canals, 10% of salivary glands, and 6% of bacteriomes dissected from the nymphs. Results of real-time polymerase chain reaction confirmed that fewer fifth instars were infected with Liberibacter compared with adults and indicated that fifth instars were less likely to transmit the pathogen to noninfected host plants. These observations of the localization of 'Ca. Liberibacter solanacearum' in the organs and tissues of B. cockerelli adults and nymphs will aid the study of Liberibacter-psyllid interactions and the epidemiology of 'Ca. Liberibacter solanacearum.'

Understanding plant response to grazing following summer fire is required to reduce ecological and financial risks associated with wildfire. Forty 0.75-ha plots were assigned to summer fire then 0, 17, 34 or 50% biomass removal by grazing the following growing season, or no fire and no grazing. Root, litter, and aboveground biomass were measured before fire, immediately after grazing, and 1 yr after grazing with the experiment repeated during 2 yr to evaluate weather effects. Fire years were followed by the second driest and fifth wettest springs in 70 yr. Biomass was more responsive to weather than fire and grazing, with a 452% increase from a dry to wet year and 31% reduction from a wet to average spring. Fire reduced litter 53% and had no first-year effect on productivity for any biomass component. Grazing after fire reduced postgrazing grass biomass along the prescribed utilization gradient. Fire and grazing had no effect on total aboveground productivity the year after grazing compared to nonburned, nongrazed sites (1327 vs. 1249 plus or minus 65 kg.ha-1). Fire and grazing increased grass productivity 16%, particularly for Pascopyrum smithii. The combined disturbances reduced forbs (51%), annual grasses (49%), and litter (46%). Results indicate grazing with up to 50% biomass removal the first growing season after summer fire was not detrimental to productivity of semiarid rangeland plant communities. Livestock exclusion the year after summer fire did not increase productivity or shift species composition compared to grazed sites. Reduction of previous years' standing dead material was the only indication that fire may temporarily reduce forage availability. The consistent responses among dry, wet, and near-average years suggest plant response is species-specific rather than climatically controlled.

Merr.]. The actual effect of maturity on disease severity can be confounded by genotypic background. We evaluated disease severity using two sets of near-isogenic lines (NIL) differing in maturity genes. Field experiments were established on two soil types (sandy loam and clay) and evaluated over two years (2008 and 2009). Disease severity, expressed as colony-forming units (CFU), was evaluated for each line at physiological maturity. Within a year, similar levels of disease severity were observed on both soil types. Regression analysis indicated no significant (P < 0.05) relationship between maturity and CFU for either set of NIL on either soil type in either year. Adding selected environmental variables (rainfall, temperature, etc.) to the equation allowed the detection of a significant relationship in only one environment (P = 0.0306, F = 6.00). Results demonstrated little evidence of a relationship between maturity and disease severity.

Laboratory, enclosure, and field-scale experiments were established to evaluate the effects of fertilizer P management on algal/cyanobacterial growth. Two field-scale experiments evaluated the response of algal/cyanobacterial growth to three P management strategies: conventional surface applied, incorporated into the soil, and delaying P applications by 30 days. Results from these experiments indicated rice fields that received conventional surface-applied P fertilizer had 4-8 times more algal/cyanobacterial biomass and 3-11 times higher concentrations of soluble reactive phosphate (SRP) than those in which P fertilizer was incorporated or delayed. Laboratory experiments evaluated the ability of field water to support growth of Nostoc spongiaeforme. Results indicate that water from the incorporated or delayed P application fields was P limited for N. spongiaeforme growth. Water from the surface-applied fields was not P limited. Enclosure experiments evaluated the effects of delayed P applications on algal/cyanobacterial biomass and rice yields. Algal/cyanobacterial cover and biomass increased in enclosures which received added P. Soluble reactive phosphate concentrations were also significantly greater in these enclosures. Delaying the application by up to 28 days did not reduce rice yields in the enclosures. One management implication is that reducing SRP concentrations early in the season in rice field water will result in reduced algal/cyanobacterial biomass. Strategies to reduce water SRP include incorporating fertilizer P or delaying the P application by up to 30 days.

In fact, non-O157 serotypes are now estimated to cause over half of all the Shiga toxin-producing Escherichia coli (STEC) cases, and outbreaks of non-O157 EHEC infections are frequently associated with serotypes O26, O45, O103, O111, O121, and O145. Currently, there are no complete genomes for O145 in public databases. Results: We determined the complete genome sequences of two O145 strains (EcO145), one linked to a US lettuce-associated outbreak (RM13514) and one to a Belgium ice-cream-associated outbreak (RM13516). Both strains contain one chromosome and two large plasmids, with genome sizes of 5,737,294 bp for RM13514 and 5,559,008 bp for RM13516. Comparative analysis of the two EcO145 genomes revealed a large core (5,173 genes) and a considerable amount of strain-specific genes. Additionally, the two EcO145 genomes display distinct chromosomal architecture, virulence gene profile, phylogenetic origin of Stx2a prophage, and methylation profile (methylome). Comparative analysis of EcO145 genomes to other completely sequenced STEC and other E. coli and Shigella genomes revealed that, unlike any other known non-O157 EHEC strain, EcO145 ascended from a common lineage with EcO157/EcO55. This evolutionary relationship was further supported by the pangenome analysis of the 10 EHEC str ains. Of the 4,192 EHEC core genes, EcO145 shares more genes with EcO157 than with the any other non-O157 EHEC strains. Conclusions: Our data provide evidence that EcO145 and EcO157 evolved from a common lineage, but ultimately each serotype evolves via a lineage-independent nature to EHEC by acquisition of the core set of EHEC virulence factors, including the genes encoding Shiga toxin and the large virulence plasmid. The large variation between the two EcO145 genomes suggests a distinctive evolutionary path between the two outbreak strains. The distinct methylome between the two EcO145 strains is likely due to the presence of a BsuBI/PstI methyltransferase gene cassette in the Stx2a prophage of the strain RM13514, suggesting a role of horizontal gene transfer-mediated epigenetic alteration in the evolution of individual EHEC strains.

AN - 1494304086; 24352475 AB - The fungus Fusarium oxysporum causes wilt diseases of plants and produces a potent phytotoxin fusaric acid (FA), which is also toxic to many microorganisms. An Aspergillus tubingensis strain with high tolerance to FA was isolated from soil and designated as CDRAt01. HPLC analysis of culture filtrates from A. tubingensis isolate CDRAt01 grown with the addition of FA indicated the formation of a metabolite over time that was associated with a decrease of FA. Spectral analysis and chemical synthesis confirmed the compound as 5-butyl-2-pyridinemethanol, referred to here as fusarinol. The phytotoxicity of fusarinol compared to FA was measured by comparing necrosis induced in cotton (Gossypium hirsutum L. cv. Coker 312) cotyledons. Fusarinol was significantly less phytotoxic than FA. Therefore, the A. tubingensis strain provides a novel detoxification mechanism against FA which may be utilized to control Fusarium wilt.

In ruminant animals, the majority of their nutrients are obtained via pregastric fermentation; however, up to 20% can be recovered from microbial fermentation in the large intestine. Eight-week continuous culture enrichments of cattle feces with cellulose and xylan-pectin were used to isolate bacteria from this community. A total of 459 bacterial isolates were classified phylogenetically using 16S rRNA gene sequencing. Six phyla were represented: Firmicutes (51.9%), Bacteroidetes (30.9%), Proteobacteria (11.1%), Actinobacteria (3.5%), Synergistetes (1.5%), and Fusobacteria (1.1%). The majority of bacterial isolates had <98.5% identity to cultured bacteria with sequences in the Ribosomal Database Project and thus represent new species and/or genera. Within the Firmicutes isolates, most were classified in the families Lachnospiraceae, Ruminococcaceae, Erysipelotrichaceae, and Clostridiaceae I. The majority of the Bacteroidetes were most closely related to Bacteroides thetaiotaomicron, B. ovatus, and B. xylanisolvens and members of the Porphyromonadaceae family. Many of the Firmicutes and Bacteroidetes isolates were related to species demonstrated to possess enzymes which ferment plant cell wall components; the others were hypothesized to cross-feed these bacteria. The microbial communities that arose in these enrichment cultures had broad bacterial diversity. With over 98% of the isolates not represented as previously cultured, there are new opportunities to study the genomic and metabolic capacities of these members of the complex intestinal microbiota.

Selected NYC pedons were analyzed by aqua regia microwave digestion and sequential chemical extraction as follows: water soluble (WS); exchangeable (EX); specifically sorbed/carbonate bound (SS/CAR); oxide-bound (OX); organic/sulfide bound (OM/S). Soils showed a range in properties (e.g., pH 3.9 to 7.4). Sum of total extractable (SUM sub(TE)) trace elements was higher in NYC parks compared to Bronx River watershed sites. NYC surface horizons showed higher total extractable (TE) levels compared to US non-anthropogenic soils. TE levels increased over 10 year in some of the relatively undisturbed and mostly wooded park sites. Surface horizons of park sites with long-term anthropogenic inputs showed elevated TE levels vs. subsurface horizons. Conversely, some Bronx River watershed soils showed increased concentrations with depth, reflective of their formation in a thick mantle of construction debris increasing with depth and intermingled with anthrotransported soil materials. Short-range variability was evident in primary pedons and satellite samples (e.g., Pb 253 plus or minus 143 mg/kg). Long-range variability was indicated by Pb sub(TE) (348 versus 156 mg/kg) and Hg sub(TE) (1 versus 0.3 mg/kg) concentrations varying several-fold in the same soil but in different geographic locations.

However, individual processing plants still experience sporadic peaks in contamination rates where multiple E. coli O157:H7-positive lots are clustered in a short time frame. These peaks have been referred to as "high event periods" (HEP) of contamination. The results reported here detail the characterization of E. coli O157:H7 isolates from 21 HEP across multiple companies and processing plants to gain insight regarding the mechanisms causing these incidents. Strain genotypes were determined by pulsed-field gel electrophoresis, and isolates were investigated for characteristics linking them to human illness. Through these analyses, it was determined that individual HEP show little to no diversity in strain genotypes. Hence, each HEP has one strain type that makes up most, if not all, of the contamination. This is shown to differ from the genotypic diversity of E. coli O157:H7 found on the hides of cattle entering processing plants. In addition, it was found that a large proportion (81%) of HEP are caused by strain types associated with human illness. These results pose a potential challenge to the current model for finished product contamination during beef processing.

Using phylogenies of the bark louse genus Ptycta (Psocidae), we compared results from biogeographical character mapping with those from molecular dating analyses. These results were used to evaluate the 'progression model', which predicts an oldest-to-youngest pattern of island colonization. The main Hawaiian Islands (Kauai, Oahu, Maui, Lanai, Molokai and Hawaii). With a data set including 101 Hawaiian Ptycta specimens and 18 outgroup species, we constructed molecular phylogenies based on sequences of the nuclear gene wingless and mitochondrial genes 12S, 16S and cytochrome c oxidase subunit I (COI). Maximum-likelihood, maximum-parsimony and Bayesian phylogenetic analyses were used. We used beast to estimate a time-calibrated tree under a relaxed clock model. Our analyses suggested a single colonization event, followed by extensive movement of Ptycta among islands and species radiations within and between islands. This monophyletic radiation is composed of two well-supported clades that are also supported by two synapomorphic characters of the male genitalia. Very different biogeographical patterns are inferred by molecular dating versus approaches based on character mapping. Simple biogeographical reconstruction over the molecular phylogeny supports a pattern of youngest-to-oldest island colonization, the reverse of that predicted by the 'progression model', and implies that this radiation could be as young as the most recent islands of Maui (1.4 Ma) or Hawaii (0.5 Ma). Molecular dating, however, infers a pattern consistent with oldest-to-youngest island colonization, and suggests a lineage age of 7.1 Ma. Extinction on the oldest island of Kauai may account for the differences in results between the two analyses.

The principal aim of our study was to investigate the photosynthetic benefit from prey capture in the carnivorous sundew Drosera capensis. Methods Prey attraction experiments were performed, with measurements and visualization of enzyme activities, elemental analysis and pigment quantification together with simultaneous measurements of gas exchange and chlorophyll a fluorescence in D. capensis in response to feeding with fruit flies (Drosophila melanogaster). Key Results Red coloration of tentacles did not act as a signal to attract fruit flies onto the traps. Phosphatase, phophodiesterase and protease activities were induced 24 h after prey capture. These activities are consistent with the depletion of phosphorus and nitrogen from digested prey and a significant increase in their content in leaf tissue after 10 weeks. Mechanical stimulation of tentacle glands alone was not sufficient to induce proteolytic activity. Activities of beta -D-glucosidases and N-acetyl- beta -D-glucosaminidases in the tentacle mucilage were not detected. The uptake of phosphorus from prey was more efficient than that of nitrogen and caused the foliar N:P ratio to decrease; the contents of other elements (K, Ca, Mg) decreased slightly in fed plants. Increased foliar N and P contents resulted in a significant increase in the aboveground plant biomass, the number of leaves and chlorophyll content as well as A sub(N), maximum quantum yield (F sub(v)/F sub(m)) and effective photochemical quantum yield of photosystem II ( Phi sub(PSII)). Conclusions According to the stoichiometric relationships among different nutrients, the growth of unfed D. capensis plants was P-limited. This P-limitation was markedly alleviated by feeding on fruit flies and resulted in improved plant nutrient status and photosynthetic performance. This study supports the original cost/benefit model proposed by T. Givnish almost 30 years ago and underlines the importance of plant carnivory for increasing phosphorus, and thereby photosynthesis.

Interestingly, many trees and lianas that comprise the wet forests increase their productivity as a response to El Nino. Here, we quantify the abundance of migrating Marpesia chiron butterflies over 17 yr and the production of new leaves of their hostplants over 9 yr to test the generality of the El Nino migration syndrome, i.e., whether increased abundance of migrating insects and productivity of their food plants are associated with El Nino and La Nina events. We find that the quantity of M. chiron migrating across the Panama Canal was directly proportional to the sea surface temperature (SST) anomaly of the Pacific Ocean, which characterizes El Nino and La Nina events. We also find that production of new leaves by its larval host trees, namely Brosimum alicastrum, Artocarpus altilis, and Ficus citrifolia, was directly proportional to the SST anomaly, with greater leaf flushing occurring during the period of the annual butterfly migration that followed an El Nino event. Combining these and our previously published results for the migratory butterfly Aphrissa statira and its host lianas, we conclude that dry season rainfall and photosynthetically active radiation can serve as primary drivers of larval food production and insect population outbreaks in Neotropical wet forests, with drier years resulting in enhanced plant productivity and herbivore abundance. Insect populations should closely track changes in both frequency and amplitude of the El Nino Southern Oscillation with climate change.Original Abstract: Resumen En el bosque humedo de Panama el fenomeno de 'El Nino' se asocia, tipicamente, con una mayor duracion y severidad de la estacion seca. En respuesta a las condiciones durante 'El Nino', muchas especies de arboles y lianas aumentan su productividad. En este estudio presentamos una cuantificacion de la abundancia de la especies de mariposa migratoria Marpesia chiron durante 17 anos, asi como de la produccion de hojas nuevas de sus plantas hospederas nuevas durante 9 anos. Nuestro objetivo es evaluar la generalidad del sindrome migratorio de El Nino, de acuerdo al cual existe una asociacion entre el incremento en la abundancia de insectos migratorios, el incremento en la productividad de las plantas hospederas y los fenomenos de La Nina y el Nino. Nuestros analisis muestran que la cantidad de individuos de M. chiron que migran a traves del canal de Panama fue directamente proporcional a la anomalia de temperatura superficial del mar (ATSM) del oceano Pacifico, la cual caracteriza los episodios de El Nino y La Nina. Tambien encontramos que la produccion de hojas nuevas de las plantas hospederas Brosimum alicastrum, Artocarpus altilis y Ficus citrifolia fue directamente proporcional a la ATSM con una mayor produccion de hojas durante el periodo migratorio que siguio El Nino. Al combinar estos datos con nuestros resultados publicados anteriormente de la especie migratoria Aphrissa statira y sus lianas hospederas, concluimos que la lluvia durante la estacion seca y la radiacion fotosintetica activa pueden funcionar como los factores que determinan la produccion de comida para las larvas y la explosion de poblaciones de insectos en bosques humedos Neotropicales, conduciendo a incrementos en la productividad de las plantas y abundancia de herbivoros durante los anos de mayor sequia. Dados estos resultados se espera que las poblaciones de insectos sigan de cerca los cambios en frecuencia y amplitud de la 'Oscilacion del Sur El Nino' causados por el cambio climatico.

This has important implications for the biological control of invasive plants because it means that agents that deter pollinators may have a larger than expected impact on the plant. Yet interactions between pollinators and biocontrol agents are rarely evaluated. Centaurea solstitialis, one of the most problematic invasive species in California, is dependent on pollinators for reproduction. I factorially manipulated infection by a biocontrol pathogen and pollen supplementation to test for (1) pollen limitation in C. solstitialis, (2) whether infection increased pollen limitation, and (3) whether this varied across a soil moisture gradient. Plants growing on north-facing slopes where soil moisture was higher experienced mild pollen limitation in the absence of the pathogen and more pronounced pollen limitation when they were infected. Plants on drier south-facing slopes did not suffer from pollen limitation but instead appeared to suffer from resource limitation. Pathogen infection directly reduced seed set in C. solstitialis by 67-72 %. On north-facing slopes, infection had an additional, indirect effect by increasing the degree of pollen limitation plants experienced. The trait that mediates this indirect pathogen-pollinator interaction is the number of inflorescences plants produced: infected plants made fewer inflorescences which led to greater pollen limitation. Although in the present study this outcome is dependent on abiotic factors that vary over small spatial scales, exploiting other invasive plants' dependence on pollinators by selecting agents that deter visitation may enhance agent impact.

We determined the distribution of soil microbial biomass, phosphomonoesterases' activity, and P forms in a 10-ha no-till field that received annual additions of dairy manure at 0, 15, and 30 kg P ha super(-1) at the field scale for 16 consecutive years. The spatial structure of soil microbial indices and extractable P fractions were characterized based on their semivariance distributions for each manure treatment. The buildup in soil P occurred, although replacement was done at a crop removal rate. Manure additions resulted in overall mean increases in total labile P of 73 % and 156 % and alterations in the soil microbial ecosystem that depended on manure inorganic-to-enzyme-labile P composition in soils treated with 15 and 30 kg P ha super(-1) , respectively. Distinct clusters of phosphate- and enzyme-labile organic P were observed within manure treatments, where accumulation of the latter forms was associated with high soil microbial biomass C and reduced acid phosphomonoesterase activity. The geographic variability highlighted the critical need for improving methods of field-scale application of manure and non-mobile nutrients. In addition, current soil testing methods that depend upon composite representative samples for estimating microbiological parameters linked to nutrient turnover and P requirements for optimal crop production should be modified to include site-specificity in sampling and interpretation approaches.

AN - 1492626055; 18957684 AB - How animals sense, process, and use magnetic information remains elusive. In insects, magnetic particles are candidates for a magnetic sensor. Recent studies suggest that the ant Pachycondyla marginata incorporates iron-containing particles from soil. We used leaf-cutter ants Atta colombica to test whether soil contact is necessary for developing a functional magnetic compass. A. colombica is the only invertebrate known to calculate a path-integrated home vector using a magnetic compass. Here, we show that A. colombica requires contact with soil to incorporate magnetic particles that can be used as a magnetic compass; yet, we also show that ants can biosynthesize magnetic particles. Workers from a soil-free colony ignored a 90 degree shift in the horizontal component of the geomagnetic field, yet oriented homeward despite the occlusion of any geocentric cues. In contrast, workers from a soil-exposed colony oriented to an intermediate direction between their true and subjective home in the shifted field. Homeward orientations under shifted fields suggest that ants calculated a path-integrated vector using proprioceptive information. Strikingly, ants from the soil-free colony also had magnetic particles; yet, as observed by ferromagnetic resonance, these particles differed from those in soil-exposed ants and were not associated with a magnetic compass sensitive to this experimental manipulation.
