TI Spatial distribution and source of potential toxic elements (PTEs) in urban soils of Guangzhou, China SO ENVIRONMENTAL EARTH SCIENCES LA English DT Article DE Multivariate analysis; Geostatistical analysis; Potential toxic elements (PTEs); Spatial distribution maps; Source identification; Urban soil ID HEAVY-METAL CONTAMINATION; GIS-BASED APPROACH; GEOCHEMICAL SURVEY; INDUSTRIAL-CITY; SOURCE IDENTIFICATION; EUROPEAN CITIES; TRACE-ELEMENTS; NEW-ORLEANS; HONG-KONG; LAND USES AB Potential toxic elements (PTEs) in urban soils are of great environmental concern because of their potential long-term effects on human health. A systematic soil geochemical survey was performed across central urban districts of Guangzhou, the largest city in southern China. Surface soil samples (0-10 cm) were collected from 426 sites in order to evaluate the environmental quality of this urban area. Geostatistical and multivariate analysis (principal component, clustering, and correlation) were applied to generate spatial distribution maps of PTEs concentrations as well as identify possible sources of metals. The results showed that PTEs ranged widely in value; Arsenic, Hg, Pb, Cu Zn, Cd, Ni, and Mn ranged from 1.4 to 144, 0.01 to 12.2, 18.5 to 4903, 5.0 to 417, 10.1 to 1795, 0.03 to 2.41, 2.5 to 77.6, and 21.2 to 1286 mg/kg, respectively. Iron ranged from 6.1 to 61.8 g/kg. Soils were enriched with Cd, Cu, Hg, Mn, Pb and Zn as compared with soil background values of Guangzhou. Spatial distribution maps indicated similar distribution patterns of Cd, Cu, Pb and Zn. Urbanization history and industrial activities affected the accumulation of PTEs. Relatively higher concentrations of As, Cd, Cu, Hg, Pb and Zn were found in districts with a longer history of urbanization and industrial activities, such as the Liwan district along the Pearl River in western Guangzhou. This area was the most highly contaminated, whereas the Tianhe, a district with a limited time of development, was the least contaminated. Multi-variate statistical analysis showed distinctly different associations among the studied metals; suggesting that Fe, Ni and Mn were predominantly derived from a natural (geological) source; As, Cu, Hg, Pb and Zn from anthropogenic sources; and Cd from both sources. Present PTEs levels were also compared with those reported from other urban areas around world, and results indicate that further studies on assessing both the human and ecosystem risks associated with urban contaminated soils will be necessary.

Escherichia coli isolates (n = 493) were screened for the presence of the following virulence genes: stx1, stx2 and eae (Shiga toxin-producing E. coli [STEC]), heat-labile enterotoxin (LT) genes and heat stable toxin STa and STb (enterotoxigenic E. coli (ETEC), cytotoxin necrotizing factors 1 and 2 (cnf1 and cnf2 [necrotoxigenic E. coli-NTEC]), as well as O and H antigens, and the presence of the antibiotic resistance genes bla(TEM), bla(SHV), bla(CMY-2), tet A, tet B, tet C, mph(A), aadA, StrA/B, sul1, sul2 and sul3. The commensal strains were further screened for 16 antimicrobials and characterized by BOX AIR-1 PCR for unique genotypes. The highest antibiotic resistance prevalence was for tetracycline, followed by erythromycin, ampicillin, streptomycin, sulfisoxazole and kanamycin. Our data showed that most of the isolates had high distribution of single or multidrug-resistant (MDR) genotypes. Therefore, the occurrence of MDR E. coli in the wetland is a matter of great concern due to possible transfer of resistance genes from nonpathogenic to pathogenic strains or vice versa in the environment.

Although early outcome results are promising, additional research is needed to determine the game design and behavior change procedures that best promote G4H effectiveness and to identify and minimize possible adverse effects. Guidelines for ideal use of different types of G4H by children and adolescents should be elucidated to enhance effectiveness and minimize adverse effects. G4H stakeholders include organizational implementers, policy makers, players and their families, researchers, designers, retailers, and publishers. All stakeholders should be involved in G4H development and have a voice in setting goals to capitalize on their insights to enhance effectiveness and use of the game. In the future, multiple targeted G4H should be available to meet a population's diverse health needs in developmentally appropriate ways. Substantial, consistent, and sophisticated research with appropriate levels of funding is needed to realize the benefits of G4H.

The ultrahigh dimensionality of big data brings unprecedented challenges to statistical modeling such as noise accumulation, the curse of dimensionality, computational burden, spurious correlations, and a processing and storing bottleneck. The traditional statistical approaches lose their power due to p >> n (n is the number of observations and p is the number of SNPs) and the complex correlation structure among SNPs. In this article, we propose an integrated distance correlation ridge regression (DCRR) approach to accommodate the ultrahigh dimensionality, joint polygenic effects of multiple loci, and the complex LD structures. Initially, a distance correlation (DC) screening approach is used to extensively remove noise, after which LD structure is addressed using a ridge penalized multiple logistic regression (LRR) model. The false discovery rate, true positive discovery rate, and computational cost were simultaneously assessed through a large number of simulations. A binary trait of Arabidopsis thaliana, the hypersensitive response to the bacterial elicitor AvrRpm1, was analyzed in 84 inbred lines (28 susceptibilities and 56 resistances) with 216,130 SNPs. Compared to previous SNP discovery methods implemented on the same data set, the DCRR approach successfully detected the causative SNP while dramatically reducing spurious associations and computational time.

Two model selection/model averaging strategies were used: the average of all available GCMs and the average of the models that are able to reproduce the observed large-scale dynamics that control precipitation over the Caribbean. Five island-wide and multidecadal averages of daily precipitation and temperature were estimated by way of a climatology-informed interpolation of the site-specific downscaled climate model output. Annual cooling degree-days (CDD) were calculated as a proxy index for air-conditioning energy demand, and two measures of annual no-rainfall days were used as drought indices. Holdridge life zone classification was used to map the possible ecological effects of climate change. Precipitation is predicted to decline in both model ensembles, but the decrease was more severe in the "regionally consistent" models. The precipitation declines cause gradual and linear increases in drought intensity and extremes. The warming from the 1960-90 period to the 2071-99 period was 4.6 degrees-9 degrees C depending on the global emission scenarios and location. This warming may cause increases in CDD, and consequently increasing energy demands. Life zones may shift from wetter to drier zones with the possibility of losing most, if not all, of the subtropical rain forests and extinction risks to rain forest specialists or obligates.

Previously, we demonstrated that rats fed a control diet and submitted to an acute restraint stress exhibited a delayed mitochondria] permeability transition pore (mPTP) opening. In this study, we evaluated the combined effects of dietary and emotional stressors as found in western way of life. We studied, in rats submitted or not to an acute stress, the effects of diet-induced IR on brain mitochondria, using a high fat/high fructose diet (HF2), as an IR inducer, with addition or not of cinnamon as an insulin sensitizer. We measured Ca2+ retention capacity, respiration, ROS production, enzymatic activities and cell signaling activation. Under stress, HF2 diet dramatically decreased the amount of Ca2+ required to open the mPTP (13%) suggesting an adverse effect on mitochondrial survival. Cinnamon added to the diet corrected this negative effect and resulted in a partial recovery (30%). The effects related to cinnamon addition to the diet could be due to its antioxidant properties or to the observed modulation of PI3K-AKT-GSK3 beta and MAPK-P38 pathways or to a combination of both. These data suggest a protective effect of cinnamon on brain mitochondria against the negative impact of an HF2 diet. Cinnamon could be beneficial to counteract deleterious dietary effects in stressed conditions. (C) 2015 Elsevier Inc. All rights reserved.

Because some barley seed is imported, there is the potential for introduction of new seed transmitted viruses, causing diseases which may spread. Barley cultivation in South Korea is expanding nationwide due to the increasing popularity of health foods, so both production and quality of barley grain is important. Although Barley stripe mosaic virus (BSMV) has been reported previously as a small percentage of all barley viruses present in Korea, increases in imports of barley seed may lead to increased occurrence of this seed transmitted virus. We therefore investigated the virus status of barley crops around Iksan and Wanju. On several newly cultivated barley farms, we observed areas showing symptoms typical of BSMV, and confirmed BSMV infection in 24% of the samples examined. In order to understand the occurrence and seed transmission of Korean BSMV isolates, we examined sequence variation within the Triple Gene Block proteins, and subcellular localization of two of these proteins. The newly identified Korean BSMV isolates show low sequence variability and high sequence homology to previously reported US isolates. With these results, we expect to confirm distribution of barley viruses and possible emerging viruses, which will serve as base line data to document virus prevention and control measures.

CA World Hlth Org Foodborne Epidemiology Reference G Source Attribution Task Force TI Research Synthesis Methods in an Age of Globalized Risks: Lessons from the Global Burden of Foodborne Disease Expert Elicitation SO RISK ANALYSIS LA English DT Editorial Material DE Disease burden; expert elicitation; expert judgment; exposure estimates; foodborne illness; research synthesis; source attribution; systematic review; uncertainty quantification ID ADJUSTED LIFE YEARS; PATHOGENS; JUDGMENT; MODEL; FOOD AB We live in an age that increasingly calls for national or regional management of global risks. This article discusses the contributions that expert elicitation can bring to efforts to manage global risks and identifies challenges faced in conducting expert elicitation at this scale. In doing so it draws on lessons learned from conducting an expert elicitation as part of the World Health Organizations (WHO) initiative to estimate the global burden of foodborne disease; a study commissioned by the Foodborne Disease Epidemiology Reference Group (FERG). Expert elicitation is designed to fill gaps in data and research using structured, transparent methods. Such gaps are a significant challenge for global risk modeling. Experience with the WHO FERG expert elicitation shows that it is feasible to conduct an expert elicitation at a global scale, but that challenges do arise, including: defining an informative, yet feasible geographical structure for the elicitation; defining what constitutes expertise in a global setting; structuring international, multidisciplinary expert panels; and managing demands on experts' time in the elicitation.

TI The interaction of two-spotted spider mites, Tetranychus urticae Koch, with Cry protein production and predation by Amblyseius andersoni (Chant) in Cry1Ac/Cry2Ab cotton and Cry1F maize SO TRANSGENIC RESEARCH LA English DT Article DE Tri-trophic exposure; Cry1Ac; Cry2Ab; Cry1F; Environmental risk assessment; Biological control ID TRANSGENIC INSECTICIDAL CROPS; PERSIMILIS ATHIAS-HENRIOT; BT-MAIZE; BIOLOGICAL-CONTROL; METAANALYSIS RESPONSE; LEPIDOPTERA-NOCTUIDAE; ACARINA-PHYTOSEIIDAE; DIGESTIVE PHYSIOLOGY; NONTARGET ARTHROPODS; CHRYSOPERLA-CARNEA AB Crops producing insecticidal crystal (Cry) proteins from the bacterium, Bacillus thuringiensis (Bt), are an important tool for managing lepidopteran pests on cotton and maize. However, the effects of these Bt crops on non-target organisms, especially natural enemies that provide biological control services, are required to be addressed in an environmental risk assessment. Amblyseius andersoni (Acari: Phytoseiidae) is a cosmopolitan predator of the two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), a significant pest of cotton and maize. Tri-trophic studies were conducted to assess the potential effects of Cry1Ac/Cry2Ab cotton and Cry1F maize on life history parameters (survival rate, development time, fecundity and egg hatching rate) of A. andersoni. We confirmed that these Bt crops have no effects on the biology of T. urticae and, in turn, that there were no differences in any of the life history parameters of A. andersoni when it fed on T. urticae feeding on Cry1Ac/Cry2Ab or non-Bt cotton and Cry1F or non-Bt maize. Use of a susceptible insect assay demonstrated that T. urticae contained biologically active Cry proteins. Cry proteins concentrations declined greatly as they moved from plants to herbivores to predators and protein concentration did not appear to be related to mite density. Free-choice experiments revealed that A. andersoni had no preference for Cry1Ac/Cry2Ab cotton or Cry1F maize-reared T. urticae compared with those reared on non-Bt cotton or maize. Collectively these results provide strong evidence that these crops can complement other integrated pest management tactics including biological control.

By measuring rates of physiological processes, we examined the trade-off between water exploitation and drought tolerance among seedlings of trees of a tropical dry forest, and identified biophysical traits most closely associated with plant water-use strategies. We also explored whether early and late secondary successional species occupy different portions of trade-off axes. As predicted, species that maintained carbon capture, hydraulic function and leaf area at higher plant water deficits during drought had low photosynthetic rates, xylem hydraulic conductivity and growth rate under non-limiting water supply. Drought tolerance was associated with more dense leaf, stem and root tissues, whereas rapid resource acquisition was associated with greater stem water storage, larger vessel diameter and larger leaf area per mass invested. We offer evidence that the water exploitation versus drought tolerance trade-off drives species differentiation in the ability of tropical dry forest trees to deal with alternating water-drought pulses. However, we detected no evidence of strong functional differentiation between early and late successional species along the proposed trade-off axes, suggesting that the environmental gradient of water availability across secondary successional habitats in the dry tropics does not filter out physiological strategies of water use among species, at least at the seedling stage.

In general, potato is an intensively managed crop, requiring irrigation, fertilization, and frequent pesticide applications in order to obtain the highest yields possible. Important traits are easy to find in wild relatives of potato, but their introduction using traditional breeding can take 15-20 years. This is due to sexual incompatibility between some wild and cultivated species, a desire to remove undesirable wild species traits from adapted germplasm, and difficulty in identifying broadly applicable molecular markers. Fortunately, potato is amenable to propagation via tissue culture and it is relatively easy to introduce new traits using currently available biotech transformation techniques. For these reasons, potato is arguably the crop that can benefit most by modern biotechnology. The benefits of biotech potato, such as limited gene flow to conventionally grown crops and weedy relatives, the opportunity for significant productivity and nutritional quality gains, and reductions in production cost and environmental impact, have the potential to influence the marketability of newly developed varieties. In this review we will discuss current and past efforts to develop biotech potato varieties, traits that could be impacted, and the potential effects that biotech potato could have on the industry.

Continuous exposure of tubers to cineole in the vapor-phase resulted in a dose-dependent inhibition of sprout growth. Comparative studies using plant bioassay systems whose growth was differentially dependent on cell division, cell elongation, or both demonstrated that cineole had no direct effect on either process. Of the assays used, only cineole-mediated inhibition of etiolated hypocotyl growth mirrored the inhibition of tuber sprout growth which suggested an effect on gibberellin synthesis or action. Both GA(19) and GA(20) were detected in extracts prepared from control sprouts but only GA(19) was found in extracts prepared from cineole treated sprouts. Exogenous GA(3,) GA(20), and GA(1) (but not GA(19)) reversed cineole-mediated sprout growth inhibition. Expression of genes encoding key GA metabolic enzymes was altered by cineole treatment in a manner consistent with diminished endogenous GA content. Collectively, these results suggest that the inhibition of sprout growth by low vapor-phase concentrations of cineole is in part a result of impaired GA biosynthesis resulting in a reduction in bioactive GA content.

Resistance to both diseases is necessary if growers are to reduce fungicide applications. Field resistance to late blight has previously been reported in an accession of Solanum hougasii (2n = 72). The putative aneuploid clone E53.61, derived from (S. hougasii x S. tuberosum) x S. tuberosum was obtained from C.R. Brown and crossed with three S. tuberosum clones. Thirty-five hybrid clones were evaluated for foliar late blight resistance at the Russell E. Larson Agricultural Research Center near State College, PA along with the susceptible check 'Atlantic' and for foliar early blight resistance in Presque Isle, ME along with the susceptible check 'Harley Blackwell' for 3 years (2012 to 2014). The experimental design was a randomized complete block design with two to three replications each year. The US-23 genotype of P. infestans occurred naturally and/or was used in inoculations in PA and plants were infected naturally with A. solani in ME. Relative area under the disease progress curve (RAUDPC) values were calculated based on visual assessment of foliar disease four to five times late in the season each year and subjected to statistical and stability analyses. There were significant differences among clones and the clone x environment interaction was significant for both diseases. Of the 35 hybrid clones evaluated for late blight, 16 were more resistant, 7 were more susceptible, and 12 were as susceptible as 'Atlantic'. Of those same hybrid clones evaluated for early blight, 23 were more resistant than 'Harley Blackwell'; the rest were as susceptible. Late blight resistance or susceptibility was independent of the stability of resistance, however, early blight resistance was associated with greater stability. Fourteen clones were more resistant than the check varieties for both late blight and early blight, suggesting that resistance genes for both late blight and early blight have been combined in this genetic material; three of these clones also had high specific gravity and acceptable chip color out of 10 A degrees C storage.

Globally, biomass burning is the largest source of BC emissions into the atmosphere. This study investigated the mass absorption efficiency (MAE) of biomass burning BC generated by controlled combustion of various wildland fuels during the Fire Laboratory at Missoula Experiments (FLAME). MAE values derived from a photoacoustic spectrometer (similar to 7.8 m(2)/g at a wavelength of 532 nm) were in good agreement with those suggested for uncoated BC when the emission ratios of organic carbon (OC) to elemental carbon (EC) were extremely low (i.e., below 0.3). With the increase of OC/EC, two distinct types of biomass smoke were identified. For the first type, MAE exhibited a positive dependence on OC/EC, while the overestimation of the light absorption coefficient (babs) by a filter-based method was less significant and could be estimated by a nearly constant correction factor. For the second type, MAE was biased low and correlated negatively with OC/EC, while the overestimation of babs by the filter-based method was much more significant and showed an apparent OC/EC dependence. This study suggests that BC emission factors determined by the commonly used thermal-optical methods might be sustantially overestimated for some types of biomass burning emissions. Our results also indicate that biomass burning emissions may include some liquid-like organics that can significantly bias filter-based babs measurements. (C) 2015 Elsevier Ltd. All rights reserved.

Using a yeast one-hybrid screening, we identified a putative Phytochrome-Interacting bHLH Factor (OsPIF14), as binding to the OsDREB1B promoter. bHLH proteins are able to bind to hexameric E-box (CANNTG) or N-box (CACG(A/C)G) motifs, depending on transcriptional activity. We have shown that OsPIF14 binds to the OsDREB1B promoter through two N-boxes and that the flanking regions of the hexameric core are essential for protein-DNA interaction and stability. We also showed that OsPIF14 down-regulates OsDREB1B gene expression in rice protoplasts, corroborating the OsPIF14 repressor activity observed in the transactivation assays using Arabidopsis protoplasts. In addition, we showed that OsPIF14 is indeed a phytochrome interacting factor, which preferentially binds to the active form (Pfr) of rice phytochrome B. This raises the possibility that OsPIF14 activity might be modulated by light. However, we did not observe any regulation of the OsDREB1B gene expression by light under control conditions. Moreover, OsPIF14 gene expression was shown to be modulated by different treatments, such as drought, salt, cold and ABA. Interestingly, OsPIF14 showed also a specific cold-induced alternative splicing. All together, these results suggest the possibility that OsPIF14 is involved in cross-talk between light and stress signaling through interaction with the OsDREB1B promoter. Although in the absence of stress, OsDREB1B gene expression was not regulated by light, given previous reports, it remains possible that OsPIF14 has a role in light modulation of stress responses.

Thirty-nine breast cancer survivors were randomly assigned to a RT (n = 20) or control (n = 19) group. RT performed supervized exercise three times per week. Natural killer cell (NK) and natural killer T-cell (NKT) function, and markers of inflammation (serum TNF-alpha, IL-6, IL-10, and CRP) were measured before and after training. Changes in NK and NKT cell function were analyzed using ANCOVA, with the change score the dependent variable, and the baseline value of the same variable the covariate. Effect sizes (ES) were calculated via partial eta-squared. We found a significant reduction, and large associated ESs, in the RT group compared to the control group for change in NK cell expression of TNF-alpha (p = 0.005, ES = 0.21) and NKT cell expression of TNF-alpha (p = 0.04, ES = 0.12). No differences were observed in any serum marker. Significant improvements in all measurements of strength were found in RT compared to control (p < 0.001; large ESs ranging from 0.32 to 0.51). These data demonstrate that RT has a beneficial effect on the NK and NKT cell expression of TNF-alpha indicating that RT may be beneficial in improving the inflammatory profile in breast cancer survivors.

Predators often use flexible foraging tactics, which allows them to pursue specific types of prey at the cost of reducing the likelihood of capturing other types of prey. When a pest insect has low nutritional quality or palatability for a predator, the predator is likely to reject that prey in favour of pursuing alternative, non-pest prey. This is often thought to limit the effectiveness of generalist predators in consuming aphids, which are of low nutritional quality for many generalist predators. Here, we report behavioural assays that test the hypothesis that the generalist predator, Grammonota inornata (Araneae: Linyphiidae), preferentially forages for a non-pest prey with high nutritional quality (springtails), and rejects a pest prey with low nutritional quality (aphids). In no-choice assays, molecular gutcontent analysis revealed that spiders continued to feed on the low-quality aphids at high rates, even when high-quality springtails were readily available. When provided a choice between aphids and springtails in two-way choice tests, spiders did not show the expected preference for springtails. Decision-making by spiders during foraging therefore appears to be sub-optimal, possibly because of attraction to the less frequently encountered of two preys as part of a dietary diversification strategy. These results indicate that behavioural preferences alone do not necessarily compromise the pest-suppression capacity of natural enemies: even nutritionally sub-optimal pest prey can potentially be subject to predation and suppression by natural enemies.

Maturing leaves protectively enclose younger leaves and the meristem, the pool of founder cells from which a leaf emerges. Through the maturation process, proximal sheath and distal blade tissues differentiate and are separated by the ligule and auricle structures. Here we review current research focusing on the contribution of gene regulatory factors and phytohormones on the patterning and differentiation of monocot leaves primarily focusing on research in the grasses (Poaceae). The 10 000 members of the grasses include the true grain cereals (wheat, rice, maize, etc.), biofuel crops such as sugarcane, pasture grasses, and bamboo. They are the most studied of the monocots due to their tremendous agricultural and agronomic importance. C1 [Lewis, Michael W.] USDA ARS, Ctr Plant Gene Express, Berkeley, CA USA.

The bumble bee Bombus bifarius comprises two geographically disparate color groups characterized by red-banded and black-banded abdominal pigmentation, but with a range of spatially and phenotypically intermediate populations across western North America. Microsatellite analyses have revealed that B.bifarius in the USA are structured into two major groups concordant with geography and color pattern, but also suggest ongoing gene flow among regional populations. In this study, we better resolve the relationships among major color groups to better understand evolutionary mechanisms promoting and maintaining such polymorphism. We analyze >90,000 and >25,000 single-nucleotide polymorphisms derived from transcriptome (RNAseq) and double digest restriction site associated DNA sequencing (ddRAD), respectively, in representative samples from spatial and color pattern extremes in B.bifarius as well as phenotypic and geographic intermediates. Both ddRAD and RNAseq data illustrate substantial genome-wide differentiation of the red-banded (eastern) color form from both black-banded (western) and intermediate (central) phenotypes and negligible differentiation among the latter populations, with no obvious admixture among bees from the two major lineages. Results thus indicate much stronger background differentiation among B.bifarius lineages than expected, highlighting potential challenges for revealing loci underlying color polymorphism from population genetic data alone. These findings will have significance for resolving taxonomic confusion in this species and in future efforts to investigate color-pattern evolution in B.bifarius and other polymorphic bumble bee species.

While the host response to vaccination and the mechanism of protection of this vaccine have been elucidated, the bacterial components eliciting protection have remained unclear. Here we show that highly purified serotype O1 Y. ruckeri lipopolysaccharide (LPS) is sufficient to induce a protective response to experimental challenge in rainbow trout (Oncorhynchus mykiss). Dose response experiments demonstrated that Y. ruckeri LPS at doses of 1 ng/fish and above resulted in essentially complete protection and doses as low as 0.01 ng/fish (1.38 ng/kg) resulted in significant protection, thus demonstrating the extremely high potency of this immunogen. Analysis of the Y. ruckeri genome identified a cluster of putative O-antigen biosynthetic genes specific to serotype O1 strains. This cluster primarily consisted of genes encoding proteins predicted to function in the biosynthesis of legionamic acid, a nonulosonic acid known to be part of the O-polysaccharide repeat of O1 Y. ruckeri. Mutation of the nab2 gene, a nonulosonic acid biosynthesis gene (nab gene), resulted in production of severely truncated forms of LPS. Vaccination with bacterin vaccines derived from the nab2 mutant and its wild type parent strain demonstrated that LPS is a required component of the whole-cell bacterin vaccine and suggests that LPS is the only cellular component contributing to the protective response elicited by this vaccine. We speculate that the exceptionally high potency of Y. ruckeri LPS accounts for the unusual success of this vaccine when delivered by immersion. Published by Elsevier Ltd.

However, the effects of this new technology on the uniformity of plant spacing and size as well as crop yield are not proven. Three experiments were conducted in commercial romaine heart lettuce fields in 2013 and 2014 in Imperial Valley, CA, to compare the effects of automated thinning and hand thinning on uniformity of in row spacing, plant size, and crop yield. Overhead images taken at 1 week after hand thinning indicate that thinning 8 to 11 days earlier by automated thinners did not affect plant size compared with the hand thinning treatment. However, lettuce plants in the automated thinning treatment were larger than plants in the hand thinning treatment 2 to 3 weeks after hand thinning. Automated thinners increased the uniformity of in-row spacing, increased the percentage of plants with the desired in-row spacing of 24 to 32 cm, and almost completely removed plants with an undesirable in-row spacing of 4 to 20 cm. As a result, individual lettuce plant weight and heart weight from the automated thinning plots was significantly greater and plants were more uniform compared with the hand thinned plants. Despite increases in lettuce plant size and uniformity in all three experiments, yield benefits of automated thinning were only significant in one of the three experiments due to larger plant populations resulting from hand thinning. This study suggests that automated thinning increases lettuce plant size and uniformity and makes it possible for growers to increase plant population and crop yield by optimizing in-row spacing.

TI Plant Characteristics and Growth Parameters of Vegetable Pigeon Pea Cultivars SO HORTTECHNOLOGY LA English DT Article DE Cajanus cajan; plant height; pod development; flowering; maturity; eastern Kenya ID TEMPERATURE; YIELD AB Pigeon pea (Cajanus cajan) is an important crop in dry land and semiarid regions and is a supplementary source of dietary protein for the economic resource constrained farmers. The aim of this research was to evaluate growth parameters of 12 vegetable pigeon pea cultivars at two locations in eastern Kenya. The number of days from planting to flowering, plant height, primary and secondary branches, and pod length and width were quantified in experimental plots in a randomized complete block design with three replications. Significant differences (P < 0.01) in days to 50% and 70% flowering (DTF) and plant maturity (DTM), respectively, were recorded among cultivars at both locations. The average plant height was significantly (P < 0.05) greater at Kiboko than at Kambi ya Mawe. The number of DTF and DTM were also greater at Kiboko than at Kambi ya Mawe site, because of supplemental irrigation. Similarly, mean pod length and width at Kiboko location exceeded that at Kambi ya Mawe by 6% and 8%, respectively. Positive and significant (P < 0.05) correlation coefficients between grain yield and pods per plant were observed, indicating that pod number is a useful indicator of yield potential of vegetable pigeon pea. The cultivars ICEAP 00068, ICEAP 00540, ICEAP 00554, ICEAP 00902, KAT 60/8, and MZ 2/9 were identified for high-yield potential under rain-fed conditions, whereas ICEAP 00902, ICEAP 00068, ICEAP 00557, ICEAP 00554, KAT 60.8, and MTHAWAJUNI showed the greatest potential when supplemental water applications were made. The cultivars KAT 60/8, ICEAP 00068, ICEAP 00554, and ICEAP 00902 were suitable for production under both rain-fed conditions and additional water applications. Yield potential of pigeon pea in the dry regions can be greatly enhanced by using cultivars with good plant growth characteristics and shoot density.

Virulence of T. gondii strains varies greatly in mice, and mounting evidence suggests that such variations may be relevant to the manifestation of human toxoplasmosis. Polymorphic rhoptry-secreted kinases and pseudokinases (ROP) have been demonstrated to account for murine virulence among the archetypal clonal parasite lineages that dominate the populations of North America and Europe. However, the distribution of virulence gene alleles in natural populations and the broad influence of these allele combinations on T. gondii virulence have not been examined in depth. In the present study, we performed PCR-RFLP genotyping analysis on a diverse array of globally distributed T. gondii strains at four ROP gene loci including ROP18, ROP5, ROP16 and ROP17 that were previously implicated in influencing T. gondii virulence and pathogenesis. We demonstrated through correlation with published virulence data that the combination of ROP18 and ROP5 allele types is highly predictive of T. gondii virulence across a broad range of global T. gondii isolates. These findings indicate that the importance of ROP18 and ROP5 in determining strain virulence is not limited to the North American/European archetypal lineages most commonly used in molecular studies, but also appears to apply to diverse isolates from South/central America and Asia.

TI The AMPK-related kinase SNARK regulates muscle mass and myocyte survival SO JOURNAL OF CLINICAL INVESTIGATION LA English DT Article ID DIFFERENT FIBER TYPES; SKELETAL-MUSCLE; SARCOPENIC OBESITY; MYOSIN PHOSPHATASE; LEAN MASS; NUAK2; IDENTIFICATION; MORTALITY; APOPTOSIS; GROWTH AB The maintenance of skeletal muscle mass is critical for sustaining health; however, the mechanisms responsible for muscle loss with aging and chronic diseases, such as diabetes and obesity, are poorly understood. We found that expression of a member of the AMPK-related kinase family, the SNF1-AMPK-related kinase (SNARK, also known as NUAK2), increased with muscle cell differentiation. SNARK expression increased in skeletal muscles from young mice exposed to metabolic stress and in muscles from healthy older human subjects. The regulation of SNARK expression in muscle with differentiation and physiological stress suggests that SNARK may function in the maintenance of muscle mass. Consistent with this hypothesis, decreased endogenous SNARK expression (using siRNA) in cultured muscle cells resulted in increased apoptosis and decreased cell survival under conditions of metabolic stress. Likewise, muscle-specific transgenic animals expressing a SNARK dominant-negative inactive mutant (SDN) had increased myonuclear apoptosis and activation of apoptotic mediators in muscle. Moreover, animals expressing SDN had severe, age-accelerated muscle atrophy and increased adiposity, consistent with sarcopenic obesity. Reduced SNARK activity, in vivo and in vitro, caused downregulation of the Rho kinase signaling pathway, a key mediator of cell survival. These findings reveal a critical role for SNARK in myocyte survival and the maintenance of muscle mass with age.

TI Wounding induces changes in cytokinin and auxin content in potato tuber, but does not induce formation of gibberellins SO JOURNAL OF PLANT PHYSIOLOGY LA English DT Article DE Auxin; Cytokinin; Gibberellin; Wound closing-layer; Wound periderm ID ABSCISIC-ACID; ENDOGENOUS GIBBERELLINS; INDUCED SUBERIZATION; PERIDERM FORMATION; SOLANUM-TUBEROSUM; CLOSING LAYER; CIS-ZEATIN; DORMANCY; TISSUE; BIOSYNTHESIS AB Cytokinin, auxin and gibberellin contents in resting and wound-responding potato tubers have not been fully determined and coordinated with wound-healing processes. Using a well-defined wound-healing model system, hormone content and expression of genes associated with hormone turnover were determined in tubers following wounding. Changes in hormone content were coordinated with: (I) formation and completion of the wound closing layer (0-5/6 days), and (II) initiation of phellogen and wound periderm formation (similar to 7 days). Quantifiable amounts of biologically active cytokinins (Z, DZ and IP) were not detected in resting or wound-responding tubers. However, the precursor IPA and catabolic product c-ZOG were found in small amounts in resting and wound-responding tubers. Wound-induced activation of cytokinin biosynthesis was suggested by an increase in t-ZR and c-ZR content at 0.5 days and large increases in IPA and c-ZR content by 3 days and throughout 7 days after wounding suggesting roles in II, but little or no role in I. Expression of key genes involved in cytokinin metabolism followed similar profiles with transcripts decreasing through 3 days and then increasing at 5-7 days after wounding. Both free IAA and IAA-Asp were present in resting tubers. While IAA-Asp was no longer present by 3 days after wounding, IAA content nearly doubled by 5 days and was more than 4-fold greater at 7 days compared to that in resting tuber (0 day) suggesting roles in II, but little or no role in I. Gibberellins were not present in quantifiable amounts in resting or wound-responding tubers. These results suggest that bio-active cytokinins are wound-induced, but their residency is temporal and highly regulated. The transient presence of active cytokinins and corresponding increases in IAA content strongly suggest their involvement in the regulation of wound periderm development. The absence of gibberellins indicates that they are not a regulatory component of wound-healing processes. Published by Elsevier GmbH.

Understanding differences in C uptake and cellular allocation among species from natural communities will bring new insight into many ecosystem process questions including how species changes will alter energy availability and C sequestration in aquatic ecosystems. A major limitation of current methods that measure algal C incorporation is the inability to separate the response of individual species from mixed-species assemblages. I used Fourier-transform infrared microspectroscopy to qualitatively measure inorganic C-13 isotope incorporation into individual algal cells in single species, two species, and natural phytoplankton assemblages. Lateral shifts in spectral peaks from C-13 treatments were observed in all species. Comparison of peaks associated with carbohydrates, proteins, and lipids allowed for the detection of which individuals took in C, and which macromolecules the C was used to make. For example, shifts in Spirogyra spectral peaks showed substantial C incorporation in carbohydrates. Further, shifts in peaks at 1160 cm(-1), 1108 cm(-1), 1080 cm(-1), 1048 cm(-1), and 1030 cm(-1) suggested C was being allocated into cellulose. The natural phytoplankton assemblage demonstrated how C could be tracked into co-occurring species. A diatom had large shifts in protein and carbohydrate peaks, while a green alga and euglenoid had only a few shifts in protein related peaks. Fourier-transform infrared microspectroscopy is an established, label free method for measuring the chemical composition of algal cells. However, adding a label such as C-13 isotope can greatly expand the technique's capabilities by qualitatively tracking C movement between inorganic and organic states within single cells.

Phencyclidine (PCP) suppression of PPI in animals has been studied to elucidate the pathological elements of schizophrenia. However, the molecular mechanisms underlying PCP treatment or PPI in the brain are still poorly understood. In this study, quantitative phosphoproteomic analysis was performed on the prefrontal cortex from rats that were subjected to PPI after being systemically injected with PCP or saline. PCP downregulated phosphorylation events were significantly enriched in proteins associated with long-term potentiation (LTP). Importantly, this data set identifies functionally novel phosphorylation sites on known LTP-associated signaling molecules. In addition, mutagenesis of a significantly altered phosphorylation site on xCT (SLC7A11), the light chain of system xc-, the cystine/glutamate antiporter, suggests that PCP also regulates the activity of this protein. Finally, new insights were also derived on PPI signaling independent of PCP treatment. This is the first quantitative phosphorylation proteomic analysis providing new molecular insights into sensorimotor gating. C1 [McClatchy, D. B.; Savas, J. N.; Martinez-Bartolome, S.; Park, S.

This global resurgence is likely linked to increased international travel and commerce in addition to widespread insecticide resistance. Analyses of the C. lectularius sequenced genome (650Mb) and 14,220 predicted protein-coding genes provide a comprehensive representation of genes that are linked to traumatic insemination, a reduced chemosensory repertoire of genes related to obligate hematophagy, host-symbiont interactions, and several mechanisms of insecticide resistance. In addition, we document the presence of multiple putative lateral gene transfer events. Genome sequencing and annotation establish a solid foundation for future research on mechanisms of insecticide resistance, human-bed bug and symbiont-bed bug associations, and unique features of bed bug biology that contribute to the unprecedented success of C. lectularius as a human ectoparasite.

Extensive biological diversity is reflected in substantial ecological and genetic variability within and among Trichinella taxa, and major controversy surrounds the systematics of this complex. Here we report the sequencing and assembly of 16 draft genomes representing all 12 recognized Trichinella species and genotypes, define protein-coding gene sets and assess genetic differences among these taxa. Using thousands of shared single-copy orthologous gene sequences, we fully reconstruct, for the first time, a phylogeny and biogeography for the Trichinella complex, and show that encapsulated and non-encapsulated Trichinella taxa diverged from their most recent common ancestor similar to 21 million years ago (mya), with taxon diversifications commencing similar to 10 - 7 mya.

To address the demand, plant breeders seek new sources of genetic variation to enhance the productivity, sustainability and resilience of crop varieties. Here we launch a high-resolution, open-access research platform to facilitate genome-wide association mapping in rice, a staple food crop. The platform provides an immortal collection of diverse germplasm, a high-density single-nucleotide polymorphism data set tailored for gene discovery, well-documented analytical strategies, and a suite of bioinformatics resources to facilitate biological interpretation. Using grain length, we demonstrate the power and resolution of our new high-density rice array, the accompanying genotypic data set, and an expanded diversity panel for detecting major and minor effect QTLs and subpopulation-specific alleles, with immediate implications for rice improvement.

Moose (Alces alces) is a popular large game animal, hunted for its meat and trophy antlers. Here, we report seroprevalence, isolation, and genetic characterization of T. gondii from moose from Minnesota. Antibodies against T. gondii were detected in 8 of 79 (10 %) moose tested by the modified agglutination test (MAT 1:25 or higher). The myocardium of 68 moose was bioassayed individually in mice, irrespective of serological status. T. gondii was detected in three moose (2 adults, 1 3 weeks old). The parasite from 2 adults was further propagated in cell culture. PCR-RFLP genotyping of cell culture derived tachyzoites using 10 genetic markers, SAG1, SAG2 (5' and 3' SAG2, and alt. SAG2), SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico revealed two different ToxoDB PCR-RFLP genotypes (#5, designated TgMooseUS1, and #7, TgMooseUS2). The mice inoculated with myocardium of the juvenile moose developed antibodies against T. gondii, and DNA extracted from infected mouse brain was only partially characterized by PCR-RFLP genotyping, which suggests a potential new genotype. Result documented prevalence of T. gondii in moose, and its possible transplacental/transmammary transmission of T. gondii in moose.

The use of synthetic insecticides to control mosquito vectors has caused physiological resistance and adverse environmental effects, in addition to high operational cost. Biosynthesis of silver nanoparticles has been proposed as an alternative to traditional control tools. In the present study, green synthesis of silver nanoparticles (AgNPs) using aqueous leaf extract of Bauhinia variegata by reduction of Ag+ ions from silver nitrate solution has been investigated. The bioreduced silver nanoparticles were characterized by UV-visible spectrophotometry, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray analysis (EDX), and Xray diffraction analysis (XRD). Leaf extract and synthesized AgNPs were evaluated against the larvae of Anopheles subpictus, Aedes albopictus, and Culex tritaeniorhynchus. Compared to aqueous extract, synthesized AgNPs showed higher toxicity against An. subpictus, Ae. albopictus, and Cx. tritaeniorhynchus with LC50 and LC90 values of 41.96, 46.16, and 51.92 mu g/mL and 82.93, 89.42, and 97.12 mu g/mL, respectively. Overall, this study proves that B. variegata is a potential bioresource for stable, reproducible nanoparticle synthesis and may be proposed as an efficient mosquito control agent.

TI AMPK and mTOR: sensors and regulators of immunometabolic changes during Salmonella infection in the chicken SO POULTRY SCIENCE LA English DT Article DE Salmonella; immunometabolism; immunity; kinome ID ENTERICA SEROVAR TYPHIMURIUM; IMMUNE-RESPONSES; PROTECTIVE IMMUNITY; BACTERIAL PATHOGENS; CELL PROPERTIES; PROTEIN-KINASE; FATTY-ACID; PPAR-DELTA; IN-VIVO; ENTERITIDIS AB Non-typhoidal Salmonella enterica induce an early pro-inflammatory response in chickens, but the response is short-lived, asymptomatic of clinical disease, results in a persistent colonization of the gastrointestinal (GI) tract, and can transmit infections to naive hosts via fecal shedding of bacteria. The underlying mechanisms that facilitate this persistent colonization of the ceca of chickens by Salmonella are unknown. We have begun to concentrate on the convergence of metabolism and immune function as playing a major role in regulating the host responsiveness to infection. It is now recognized that the immune system monitors the metabolic state of tissues and responds by modulating metabolic function. The aim in this review is to summarize the literature that has defined a series of genotypic and phenotypic alterations in the regulatory host immune-metabolic signaling pathways in the local cecal microenvironment during the first 4 d following infection with Salmonella enterica serovar Enteritidis. Using chicken-specific kinomic immune-metabolism peptide arrays and quantitative real-time-PCR of cecal tissue during the early (4 to 48 h) and late stages (4 to 17 d) of a Salmonella infection in young broiler chickens, the local immunometabolic microenvironment has been ascertained. Distinct immune and metabolic pathways are altered between 2 to 4 d post-infection that dramatically changed the local immunometabolic environment. Thus, the tissue immunometabolic phenotype of the cecum plays a major role in the ability of the bacterium to establish a persistent cecal colonization. In general, our findings show that AMPK and mTOR are key players linking specific extracellular milieu and intracellular metabolism. Phenotypically, the early response (4 to 48 h) to Salmonella infection is pro-inflammatory, fueled by glycolysis and mTOR-mediated protein synthesis, whereas by the later phase (4 to 5 d), the local environment has undergone an immune-metabolic reprogramming to an anti-inflammatory state driven by AMPK-directed oxidative phosphorylation. Therefore, metabolism appears to provide a potential critical control point that can impact infection. Further understanding of metabolic control of immunity during infection should provide crucial information of the development of novel therapeutics based on metabolic modulators that enhance protection or inhibit infection.

Chicken infected with Salmonella do not develop clinical disease, this may be the result of important host interactions with key virulence proteins. To study this, we inoculated chicken with mutant Salmonella Typhimurium that lacked the virulence protein AvrA (AvrA(-)). AvrA is referred to as an avirulence factor, as it moderates the host immune response. The lack of the AvrA virulence gene in ST resulted in reduced weight gain, enhanced persistence and greater extraintestinal organ invasion in chickens, as compared to wild-type (WT) ST. Kinome analysis was performed on inoculated cecal tissue. The majority of the signal transduction pathways induced by AvrA(-) and WT ST were similar; however, we observed alterations in innate immune system signaling. In addition, a leukocyte migration pathway was altered by AvrA(-) ST that may allow greater gut barrier permeability and invasion by the mutant. Cytokine expression did not appear significantly altered at 7 d post-inoculation; at 14 d post-inoculation, there was an observed increase in the expression of anti-inflammatory IL-10 in the WT inoculated ceca. This study is the first to describe mutant AvrA(-) ST infection of chicken and provides further insight into the Salmonella responses observed in chicken relative to other species such as humans and cattle.

TI Selection for pro-inflammatory mediators produces chickens more resistant to Clostridium perfringens-induced necrotic enteritis SO POULTRY SCIENCE LA English DT Article DE broiler; Clostridium perfringens; necrotic enteritis; pro-inflammatory; selection for resistance ID BROILER-CHICKENS; MODEL; COCCIDIOSIS; RESPONSES; POULTRY; HEALTH; LINES; TPEL AB We developed a novel selection method based on an inherently high and low phenotype of pro-inflammatory mediators and produced "high" and "low" line chickens. We have shown high line birds are more resistant to Salmonella enterica serovar Enteritidis and Eimeria tenella compared to the low line. Clostridium perfringens is the fourth leading cause of bacterial-induced foodborne illness, and is also an economically important poultry pathogen and known etiologic agent of necrotic enteritis (NE). The objective of this study was to determine if high line birds were also more resistant to NE than low line birds using an established model. Birds were reared in floor pens and challenges were conducted twice (high line = 25/trial, 50 birds total; low line = 26/trial, 52 birds total). Day-old chicks were provided a 55% wheat-corn-based un-medicated starter diet. A bursal disease vaccine was administered at 10x the recommended dose via the ocular route at 14-d-of-age. Birds were challenged daily for 3 d beginning at 16-d-of-age by oral gavage (3 mL) with 10(7) colony forming units (cfu) of C. perfringens/mL then necropsied at 21-d-of-age. All birds had sections of the intestine examined and scored for lesions while the first 10 necropsied also had gut content collected for C. perfringens enumeration. Chickens from the high line were more resistant to C. perfringens-induced NE pathology compared to the low line, as indicated by reduced lesion scores. Ninety percent of the high line birds had lesions of zero or one compared to 67% of the low line birds. Wilcoxon rank sum test showed significantly higher lesion scores in the low line birds compared to the high line (P < 0.0001). There were no differences in the C. perfringens recovered (P = 0.83). These data provide additional validation and support selection based on elevated levels of pro-inflammatory mediators produces chickens with increased resistance against foodborne and poultry pathogens.

TI Determining the persistence of Mycobacterium bovis bacille Calmette-Guerin Danish in select tissues of orally vaccinated feral swine (Sus scrofa ssp.) SO RESEARCH IN VETERINARY SCIENCE LA English DT Article DE Mycobacterium bovis; BCG; Feral swine; Vaccine; Bovine tuberculosis; Tissue persistence ID EUROPEAN WILD BOAR; RED DEER; IN-VIVO; TUBERCULOSIS; BCG; EPIDEMIOLOGY; TRANSMISSION; STRAINS; CATTLE AB Mycobacterium bovis bacille Calmette-Guerin (BCG) is being considered for vaccination of feral swine (Sus scrota ssp.). Since BCG is a live bacterium, evaluation of its safety and persistence in tissues is important. Fifteen feral swine received approximately 45 x 10(6) colony forming units of BCG Danish via oral bait. Four animals received bait without BCG. At 1, 3, 6, and 9 months post-vaccination, four vaccinates were euthanized. Non-vaccinates were euthanized at 9 months. Clinical signs were not noted in vaccinated pigs at any time. Tissues from all 20 pigs were culture-negative for mycobacteria. Based on our data, BCG is safe and appears not to persist in feral swine tissues after one month post-oral vaccination. However, further work must be performed at higher doses, and on a larger number of animals representing the target population, and further evaluation of persistence in tissues within the first month post-vaccination is needed.

The NE affected bird die rapidly as a result of various pathophysiological complications in the intestine and immune system. Also, several studies have reported that the genes exclusively related to intestine and immune functions are significantly altered in response to NE. In this study, NE was induced in two genetically disparate chicken lines that are resistant (line 6.3) and sensitive (line 7.2) to avian leukosis and Marek's disease. The intestinal mucosal layer was collected from NE-induced and control chickens, and subjected to RNA-sequencing analysis. The involvement of differentially expressed genes in the intestinal mucosal layer of line 6.3 and 7.2 with the immune system-related pathways was investigated. Among the identified immune system related pathways, a candidate pathway known as chicken cytosolic DNA-sensing pathway (CDS pathway) was selected for further investigation. RNA-sequencing and pathway analysis identified a total of 21 genes that were involved in CDS pathway and differentially expressed in the intestinal mucosal layer of lines 6.3 and 7.2. The expression of CDS pathway genes was further confirmed by real-time qPCR. In the results, a majority of the CDS pathway genes were significantly altered in the NE-induced intestinal mucosal layer from lines 6.3 and 7.2. In conclusion, our study indicate that NE seriously affects several genes involved in innate immune defense and foreign DNA sensing mechanisms in the chicken intestinal mucosal layer. Identifying the immune genes affected by NE could be an important evidence for the protective immune response to NE-causative pathogens. (C) 2015 Elsevier B.V. All rights reserved.

The complete genomes of six picornaviruses were determined and their genomic and phylogenetic characteristics and UTR RNA structural models analyzed in details. Picornaviruses belonged to genera Sicinivirus (the first complete genome), Gallivirus, Tremovirus, Avisivirus and "Orivirus" (two potential genotypes). In addition, the unassigned phacoviruses were also detected in multiple samples of chickens in the USA. Multiple co-infections promote and facilitate the recombination and evolution of picornaviruses and eventually could contribute to the severity of the diarrhea in chicken, in one of the most important food sources of humans.

The development of a reliable challenge model is an important prerequisite for evaluation of existing and novel vaccines. A study aimed at comparing the pathogenesis of RVF virus infection in US sheep using two genetically different wild type strains of the virus (SA01-1322 and Kenya-128B-15) was performed. A group of sheep was inoculated with both strains and all infected sheep manifested early-onset viremia accompanied by a transient increase in temperatures. The Kenya-128B-15 strain manifested higher virulence compared to SA01-1322 by inducing more severe liver damage, and longer and higher viremia. Genome sequence analysis revealed sequence variations between the two isolates, which potentially could account for the observed phenotypic differences. We conclude that Kenya-128B-15 sheep infection represents a good and virulent challenge model for RVF. (C) 2015 Elsevier Inc. All rights reserved.

Current perspectives are not capable of answering interdisciplinary adaptation and mitigation challenges posed by increases in wildfire risk to human populations and the need to reintegrate fire as a vital landscape process. Fire science has been, and continues to be, performed in isolated "silos," including institutions (e.g., agencies versus universities), organizational structures (e.g., federal agency mandates versus local and state procedures for responding to fire), and research foci (e.g., physical science, natural science, and social science). These silos tend to promote research, management, and policy that focus only on targeted aspects of the "wicked" wildfire problem. In this article, we provide guiding principles to bridge diverse fire science efforts to advance an integrated agenda of wildfire research that can help overcome disciplinary silos and provide insight on how to build fire-resilient communities.

It is now possible to describe these and other metabolically more dynamic tissues such as leaves in greater detail using novel methods in mass spectrometry, isotope labeling strategies, and transient labeling-based flux analyses. Such studies are necessary for a systems level description of plant function that more closely represents biological reality, and provides insights into the genes that will need to be modified as natural resources become ever more limited and environments change.

The nondiapausing phenotype was inherited via a single recessive gene and the phenotype with reduced low temperature exposure requirements before hatch was inherited via a single dominant gene. There was no evidence for sex-linkage or cytoplasmic effects with either gene. Eggs from 43 geographic populations were evaluated for hatch characteristics after being held for 60d at 5 degrees C followed by incubation at 25 degrees C. There was considerable variation both within and among the populations in the proportion able to hatch, time to first hatch, and average time to hatch. Egg masses with reduced requirement for low temperatures before the eggs were ready to hatch were present in all subspecies of L. dispar and the phenotype was not fixed in most populations. The populations clustered into three distinct groups, and climatic variables were found to be rough predictors of those groups. Variation in hatch phenotypes between populations is likely an adaptation to local climate and within a population provides a bet-hedging strategy to ensure that at least some hatch synchronizes with host leaf-out. Continued vigilance to prevent movement of populations both within and between countries is warranted, because some of the alleles that confer nondiapause or reduced low temperature requirements before egg hatch are not present in all populations and their introduction would increase variation in egg hatch within a population.

TI Structure of Phoretic Mite Assemblages Across Subcortical Beetle Species at a Regional Scale SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE commensalism; Dendroctonus; Ips; phoresy; Pinus ID SOUTHERN PINE-BEETLE; BARK BEETLES; COLEOPTERA; SCOLYTIDAE; DIVERSITY; ASSOCIATIONS; RAREFACTION; DYNAMICS; FUNGI AB Mites associated with subcortical beetles feed and reproduce within habitats transformed by tree-killing herbivores. Mites lack the ability to independently disperse among these habitats, and thus have evolved characteristics that facilitate using insects as transport between resources. Studies on associations between mites and beetles have historically been beetle-centric, where an assemblage of mite species is characterized on a single beetle species. However, available evidence suggests there may be substantial overlap among mite species on various species of beetles utilizing similar host trees. We assessed the mite communities of multiple beetle species attracted to baited funnel traps in Pinus stands in southern Wisconsin, northern Arizona, and northern Georgia to better characterize mite dispersal and the formation of mite-beetle phoretic associations at multiple scales. We identified approximately 21 mite species totaling 10,575 individuals on 36 beetle species totaling 983 beetles. Of the mites collected, 97% were represented by eight species. Many species of mites were common across beetle species, likely owing to these beetles' common association with trees in the genus Pinus. Most mite species were found on at least three beetle species. Histiostoma spp., Iponemus confusus Lindquist, Histiogaster arborsignis Woodring and Trichouropoda australis Hirschmann were each found on at least seven species of beetles. While beetles had largely similar mite membership, the abundances of individual mite species were highly variable among beetle species within each sampling region. Phoretic mite communities also varied within beetle species between regions, notably for Ips pini (Say) and Ips grandicollis (Eichhoff).

Scymnus camptodromus phenology is closely synchronized with that of A. tsugae and has several characteristics of a promising biological control agent. As a prerequisite to field release, S. camptodromus was evaluated for potential nontarget impacts. In host range studies, the predator was given the choice of sympatric adelgid and nonadelgid prey items. Nontarget testing showed that S. camptodromus will feed to some degree on other adelgid species, but highly prefers A. tsugae. We also evaluated larval development of S. camptodromus on pine bark adelgid (Pineus strobi (Hartig)) (Hemiptera: Adelgidae) and larch adelgid (Adelges laricis Vallot) (Hemiptera: Adelgidae); a small proportion of predator larvae was able to develop to adulthood on P. strobi or A. laricis alone. Scymnus camptodromus showed no interest in feeding on woolly alder aphid (Paraprociphilus tessellatus Fitch) (Hemiptera: Aphididae) or woolly apple aphid (Eriosoma lanigerum (Hausmann)) (Hemiptera: Aphididae), and minimal interest in cotton aphid (Aphis gossypii Glover) (Hemiptera: Aphididae) in choice and no-choice experiments. Scymnus camptodromus females did not oviposit on any host material other than A. tsugae-infested hemlock. Under the circumstances of the study, S. camptodromus appears to be a specific predator of A. tsugae, with minimal risk to nontarget species. Although the predator can develop on P. strobi, the likelihood that S. camptodromus would oviposit on pine hosts of this adelgid is small.

This study focuses on the impacts of the univoltine broom psyllid Arytainilla spartiophila Forster on the growth of its target weed, the invasive shrub Scotch broom, Cytisus scoparius (L.) Link (Fabaceae), in California. Arytainilla spartiophila is an adventive species that has been present in North America for several decades. In a greenhouse experiment, plant growth as measured by both height and total stem length (height+length of all branches) was reduced on plants that received psyllids, and psyllid densities were negatively correlated to proportional change in plant height. There were no effects on number of leaves, however. Furthermore, the psyllid had no statistically detectable impacts on plant growth parameters in a field experiment, underscoring how results obtained under controlled conditions may not fully predict the performance of biological control agents in the field. The high psyllid mortality that occurred at higher psyllid densities in both the greenhouse and the field suggests that the impacts of A. spartiophila may be moderated by intraspecific competition.

As MPB populations expanded in lodgepole pine forests in the southern Rocky Mountains, we investigated the potential for movement into adjacent ponderosa pine forests. We conducted field and laboratory experiments to evaluate four aspects of MPB population dynamics and host selection behavior in the two hosts: emergence timing, sex ratios, host choice, and reproductive success. We found that peak MPB emergence from both hosts occurred simultaneously between late July and early August, and the sex ratio of emerging beetles did not differ between hosts. In two direct tests of MPB host selection, we identified a strong preference by MPB for ponderosa versus lodgepole pine. At field sites, we captured naturally emerging beetles from both natal hosts in choice arenas containing logs of both species. In the laboratory, we offered sections of bark and phloem from both species to individual insects in bioassays. In both tests, insects infested ponderosa over lodgepole pine at a ratio of almost 2:1, regardless of natal host species. Reproductive success (offspring/female) was similar in colonized logs of both hosts. Overall, our findings suggest that MPB may exhibit equally high rates of infestation and fecundity in an alternate host under favorable conditions.

TI Larval Preference and Performance of Amyelois transitella (Navel Orangeworm, Lepidoptera: Pyralidae) in Relation to the Fungus Aspergillus flavus SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE navel orangeworm; Aspergillus flavus; preference; performance; mutualism ID FATTY-ACID-COMPOSITION; LOBESIA-BOTRANA; AFLATOXIN CONTAMINATION; BOTRYTIS-CINEREA; WATER ACTIVITY; GROUND ALMOND; EGG TRAPS; PISTACHIO; BEHAVIOR; MOTH AB The navel orangeworm, Amyelois transitella (Walker), is a polyphagous pest of California nut crops and is responsible for extensive losses in the United States. It directly damages crops by feeding and contaminating nuts with frass and webbing and vectors saprophytic fungi that infect crops. The navel orangeworm is commonly associated with Aspergillus species, including the toxigenic Aspergillus flavus, which causes crop loss by producing carcinogens, including aflatoxin B1. This lepidopteran-fungus association is the most economically serious pest complex in Central Valley orchards, and evidence indicates that this relationship is mutualistic. We assessed preference and performance of navel orangeworm larvae associated with A. flavus in behavioral bioassays in which neonates were allowed to orient within arenas to media with or without fungal tissue, and performance bioassays in which larvae were reared with and without A. flavus on potato dextrose agar (PDA) and a semidefined almond PDA diet to evaluate effects on development and pupal weight. Navel orangeworm larvae were attracted to A. flavus and developed faster in its presence, indicating a nutritional benefit to the caterpillars. Larvae reached pupation similar to 33% faster on diet containing A. flavus, and pupal weights were similar to 18% higher for males and similar to 13% higher for females on this diet. Our findings indicate that A. flavus plays an important role in larval orientation and development on infected hosts. The preference-performance relationship between navel orangeworms and Aspergillus flavus is consistent with a facultative mutualism that has broad implications for pest management efforts and basic understanding of Lepidoptera-plant interactions.

(Hymenoptera: Megachilidae). M. rotundata females nest in cavities either naturally occurring or in artificial nesting blocks. Because of the physical nature of the nest, M. rotundata brood may have limited to no exposure to photoperiodic cues in order to regulate important circadian functions. Therefore, various thermoperiod regimes were used to characterize the possible role of thermoperiodism in synchronizing M. rotundata adult emergence. Adult emergence was monitored using a microprocessor- controlled event logger. Incubating bees under constant 29 degrees C and darkness resulted in an arhythmic adult emergence pattern. Exposing developing M. rotundata to a thermoperiod synchronized emergence to the beginning of the thermophase and decreased the total number of days required for all adults to emerge. The amplitude of the thermoperiod regulated the timing of peak emergence in relationship to the increase in temperature. A thermoperiod amplitude of only 2 degrees C was sufficient to synchronize peak adult emergence to take place during the rise in temperature. Increasing the amplitude of the thermoperiod to 4 or 8 degrees C caused a positively correlated shift in peak emergence to later in the thermophase. Brood stored under constant 29 degrees C and darkness for different durations (May or June early in the growing season or July or August late in the growing season) or under a fluctuating thermal regime (base temperature of 6 degrees C and daily 1-h pulse of 20 degrees C until September or November) maintained their capacity for entraining emergence timing by thermoperiodism.

TI Development of a Fire Weather Index Using Meteorological Observations within the Northeast United States SO JOURNAL OF APPLIED METEOROLOGY AND CLIMATOLOGY LA English DT Article DE Wildfires; Statistical techniques; Regression analysis; Forest fires; Surface observations; Statistical forecasting ID CLIMATOLOGY; FOREST AB A fire weather index (FWI) is developed using wildfire occurrence data and Automated Surface Observing System weather observations within a subregion of the northeastern United States (NEUS) from 1999 to 2008. Average values of several meteorological variables, including near-surface temperature, relative humidity, dewpoint, wind speed, and cumulative daily precipitation, are compared on observed wildfire days with their climatological average ("climatology") using a bootstrap resampling approach. Average daily minimum relative humidity is significantly lower than climatology on wildfire occurrence days, and average daily maximum temperature and average daily maximum wind speed are slightly higher on wildfire occurrence days. Using the potentially important weather variables (relative humidity, temperature, and wind speed) as inputs, different formulations of a binomial logistic regression model are tested to assess the potential of these atmospheric variables for diagnosing the probability of wildfire occurrence. The FWI is defined using probabilistic output from the preferred binomial logistic regression configuration. Relative humidity and temperature are the only significant predictors in the binomial logistic regression. The binomial logistic regression model is reliable and has more probabilistic skill than climatology using an independent verification dataset. Using the binomial logistic regression output probabilities, an FWI is developed ranging from 0 (minimum potential) to 3 (high potential) and is verified independently for two separate subdomains within the NEUS. The climatology of the FWI reproduces observed fire occurrence probabilities between 1999 and 2008 over a subdomain of the NEUS.

Western corn rootworm, Diabrotica virgifera virgifera LeConte, has rapidly evolved resistance to Bt maize in the field, leading to local loss of efficacy for some corn rootworm Bt maize events. Documenting and responding to this resistance has been complicated by a lack of rapid diagnostic bioassays and by regulatory triggers that hinder timely and effective management responses. These failures are of great concern to the scientific and agricultural community. Specific challenges posed by western corn rootworm resistance to Bt maize, and more general concerns around Bt crops that produce less than a high-dose of Bt toxin, have caused uncertainty around current IRM protocols. More than 15 years of experience with IRM has shown that high-dose and refuge-based IRM is not applicable to Bt crops that produce less than a high-dose. Adaptive IRM approaches and pro-active, integrated IRM-pest management strategies are needed and should be in place before release of new technologies that produce less than a high-dose. We suggest changes in IRM strategies to preserve the utility of corn rootworm Bt maize by 1) targeting local resistance management earlier in the sequence of responses to resistance and 2) developing area-wide criteria to address widespread economic losses. We also favor consideration of policies and programs to counteract economic forces that are contributing to rapid resistance evolution.

(Coleoptera: Laemophloeidae), have been observed in H. hampei-infested coffee. Under laboratory conditions, colony-reared C. quadricollis and Leptophloeus sp. prey upon all life stages of H. hampei. However, the H. hampei life cycle occurs almost exclusively within a coffee bean obscured from direct observation. Thus, it is unknown if C. quadricollis and Leptophloeus sp. consume H. hampei as prey in the wild. To demonstrate predation of H. hampei by C. quadricollis and Leptophloeus sp., a molecular assay was developed utilizing species-specific primers targeting short regions of the mitochondrial COI gene to determine species presence. Using these primers, wild C. quadricollis and Leptophloeus sp. were collected and screened for the presence of H. hampei DNA using PCR. Analysis of collections from five coffee farms revealed predation of C. quadricollis and Leptophloeus sp. on H. hampei. Further laboratory testing showed that H. hampei DNA could be detected in predators for as long as 48 h after feeding, indicating the farm-caught predators had preyed on H. hampei within 2 d of sampling. This study demonstrates the utility of molecular markers for the study of the ecology of predators and prey with cryptic behavior, and suggests C. quadricollis and Leptophloeus sp. might be useful biocontrol agents against H. hampei.

TI Temperature-Mediated Kill and Oviposition of Western Cherry Fruit Fly (Diptera: Tephritidae) in the Presence of Spinosad SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE Rhagoletis indifferens; climate; insecticide; activity level; egg laying ID RHAGOLETIS-INDIFFERENS DIPTERA; LONGEVITY; GF-120; FECUNDITY; MORTALITY; SURVIVAL; PROGRAM; BAITS AB Western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), is a quarantine pest of sweet cherry (Prunus avium (L.) L.) that is managed using insecticides, including spinosad, an organic compound that can be applied in low spray volumes. Identifying factors that can increase the efficacy of spinosad can be useful for improving fly control. Here, the major objective was to determine if temperature mediates kill and oviposition of R. indifferens in the presence of low spinosad coverage in the laboratory. Experiments were conducted by placing flies in cages with cherries and with a Petri dish containing 3-12 small spots of dry spinosad at 18.3, 23.9, and 29.4 degrees C. Effects of spinosad rates were also determined. More flies were killed at 23.9 and 29.4 degrees C than at 18.3 degrees C by 1-7 d post exposure. More flies were killed at 29.4 than 23.9 degrees C by 1 d post exposure. However, flies laid more eggs at these temperatures than at 18.3 degrees C. Higher spinosad rates increased kill and decreased oviposition, but even within the highest rate, oviposition was greater at 29.4 than 18.3 degrees C. More flies walked over 5-min observation periods at 29.4 and 23.9 degrees C than 18.3 degrees C, suggesting higher temperatures up to 29.4 degrees C increase kill by increasing fly contact with spinosad as well as increase oviposition rate. Results suggest that spinosad rates in sprays used against R. indifferens should be greater at higher than lower ambient temperatures.

ME feeding of males of the B. dorsalis complex is known to enhance their mating competitiveness. Within B. dorsalis, recent studies show that Asian and African populations of B. dorsalis are sexually compatible, while populations of B. dorsalis and Bactrocera carambolae are relatively incompatible. The objectives of this study were to examine whether ME feeding by males affects mating compatibility between Asian and African populations of B. dorsalis and ME feeding reduces male mating incompatibility between B. dorsalis (Asian population) and B. carambolae. The data confirmed that Asian and African populations of B. dorsalis are sexually compatible for mating and showed that ME feeding only increased the number of matings. Though ME feeding also increased the number of matings of B. dorsalis (Asian population) and B. carambolae males but the sexual incompatibility between both species was not reduced by treatment with ME. These results conform to the efforts resolving the biological species limits among B. dorsalis complex and have implications for fruit fly control programs in fields and horticultural trade.

Kolarik, E. Freeland, C. Utley and N. Tisserat sp. nov. Spread of this disease may occur via movement of infested black walnut (Juglans nigra L.) wood. This study evaluated the ability of P. juglandis to colonize J. nigra wood previously treated with various phytosanitation methods. Steam-heated and methyl bromide-fumigated J. nigra logs, as well as kiln-dried natural wane J. nigra lumber (with and without bark) were subsequently exposed to P. juglandis colonization pressure in two exposure scenarios. Following a pheromone-mediated, high-pressure scenario in the canopy of infested trees, beetles readily colonized the bark of steam-heated and methyl bromide-fumigated logs, and were also recovered from kiln-dried lumber on which a thin strip of bark was retained. In the simulated lumberyard exposure experiment, during which samples were exposed to lower P. juglandis populations, beetles were again recovered from bark-on steam-heated logs, but were not recovered from kiln-dried bark-on lumber. These data suggest logs and bark-on lumber treated with phytosanitation methods should not be subsequently exposed to P. juglandis populations. Further beetle exclusion efforts for phytosanitized, bark-on walnut wood products transported out of quarantined areas may be necessary to ensure that these products do not serve as a pathway for the spread of P. juglandis and thousand cankers disease.

Third-instar F-1 nymphs from each field location, in addition to a laboratory colony, were screened for susceptibility to novaluron. Both a glass vial bioassay and a diet-incorporated bioassay used dose-response regression lines to calculate LC50 and LC90 values for novaluron. Mean LC50s for glass vial bioassays ranged from 44.706 +/- 3.58 to 66.54 +/- 64.19 mu g/vial, while mean LC50s for diet-incorporated bioassays ranged from 12.10 +/- 60.77 to 17.636 +/- 2.42 mu g/200 ml of artificial diet. A comparison of L-C50 values from the same field population screened using both bioassay methods failed to show a relationship. LC50 values from field locations were compared with a historically susceptible population from Crossett, AR. Results indicated that considerable variability in susceptibility to novaluron exists within field populations of tarnished plant bugs across the Delta, including some locations with lower LC50 values than a historically susceptible population.

Variation within and among gypsy moths from China (nine locations), one of the native countries of Asian gypsy moth, were compared using DNA barcode sequences (658 bp of mtDNA cytochrome c oxidase subunit 1 [COI] sequence), together with two restriction site mtDNA markers (NlaIII and BamHI in COI), which is the standard system used to distinguish European gypsy moths from Asian gypsy moths. Relatedness of these populations to gypsy moths from seven other world areas was also examined. The restriction site markers showed that two Chinese populations had both Asian and European haplotypes. DNA barcode sequence divergence between the Asian populations and the European populations was three times greater than the variation within each group. Using Bayesian and parsimonious network analyses, nine previously unknown barcode haplotypes were documented from China and a single haplotype was found to be shared by 55% of the Chinese and some Far Eastern Russian and Japanese individuals. Some gypsy moths from two Chinese populations showed genetic affinity with mtDNA haplotypes from Siberia, Russia, suggesting there could be a cryptic new subspecies in Lymantria dispar (L.) or human-aided movement of moths between these two locations at an earlier point in time. The previously unknown haplotype patterns may complicate efforts to identify Asian gypsy moth introductions and require changes in monitoring and exclusion programs.

However, the use of resistant wheat results in the selection of pest genotypes that can overcome formerly resistant wheat. We have evaluated the effectiveness of 16 resistance genes for protection of wheat from Hessian fly infestation in the southeastern United States. Results documented that while 10 of the genes evaluated could provide protection of wheat, the most highly effective genes were H12, H18, H24, H25, H26, and H33. However, H12 and H18 have been reported to be only partially effective in field evaluations, and H24, H25, and H26 may be associated with undesirable effects on agronomic traits when introgressed into elite wheat lines. Thus, the most promising new gene for Hessian fly resistance appears to be H33. These results indicate that identified highly effective resistance in wheat to the Hessian fly is a limited resource and emphasize the need to identify novel sources of resistance. Also, we recommend that the deployment of resistance in gene pyramids and the development of novel strategies for engineered resistance be considered.

TI Feeding Behavior of Soybean Aphid (Hemiptera: Aphididae) Biotype 2 on Resistant and Susceptible Soybean SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE Aphis glycines biotype 2; soybean; Rag2 resistance; electrical penetration graph ID SINGLE DOMINANT GENE; SALIVARY SECRETIONS; PENETRATION; PI-243540; STYLETS AB Host plant resistance to the soybean aphid, Aphis glycines Matsumura, is an effective means of controlling populations of this introduced pest species in the United States. Rag (Resistance to Aphis,glycines) genes identified in soybean germplasm have been incorporated into commercial cultivars, but differential responses by soybean aphid biotypes to the Rag genes have made understanding mechanisms underlying resistance associated with Rag genes increasingly important. We compared the behavior of biotype 2 aphids on the resistant soybean line PI243540, which is a source of Rag2, and the susceptible cultivar Wyandot. Scanning electron microscopy revealed that the abaxial surface of leaves from resistant plants had a higher density of both long and glandular trichomes, which might repel aphids, on veins. Time-lapse animation also suggested a repellent effect of resistant plants on aphids. However, electropenatography (EPG) indicated that the time to first probe did not differ between aphids feeding on the resistant and susceptible lines. EPG also indicated that fewer aphids feeding on resistant plants reached the phloem, and the time before reaching the phloem was much longer relative to susceptible soybean. For aphids that reached the phloem, there was no difference in either number of feedings or their duration in phloem. However, aphids feeding on resistant soybean had fewer prolonged phases of active salivation (El) and many more pathway activities and non-probing intervals. Together, the feeding behavior of aphids suggested that Rag2 resistance has strong antixenosis effects, in addition to previously reported antibiosis, and was associated with epidermal and mesophyll tissues.

We evaluated four new barley lines from the Wild Barley Diversity Collection (WBDC) that previously showed potential for greenbug resistance. Three of those entries, WBDC 53, WBDC 117, WBDC 336, exhibited very dominant sources of resistance to older known biotypes B, C, E, F, H, I, and TX1, which also add to the host -plant differentials used to separate these greenbug biotypes. We also re-evaluated the earlier known set of greenbug biotypes that have been in culture for several years against the known host -plant differentials, and included seven newer greenbug isolates collected from Wyoming to the full complement of small grain differentials. This resulted in the discovery of five new greenbug biotypes, VVY10 MC, VVY81, WY10 B, WY12 MC, and WY86. Wyoming isolates VVY4 A and WY4 B were identical in their phenotypic profile, and should be combined as a single unique greenbug biotype. These barley trials resulted in finding new sources of host -plant resistance, although more research needs to be conducted on what type of resistance was found, and how it can be used. We also document that the Wheatland, Wyoming area serves as a very conducive environment for the development of new greenbug biotypes. C1 [Armstrong, J.

The effect of trap seeding, adding adults of the same or different species, was evaluated in order to determine possible effects of prior captures in the trap on each species' behavioral responses. The presence of seeded beetles of the same species resulted in an increase in beetle captures for both T. castaneum and T. confusum, but when traps were seeded with the opposite species, there was no increase in beetle captures for either species, and for T. castaneum overall captures in both seeded and unseeded traps was reduced. Overall, T. castaneum tended to have greater captures than T. confusum regardless of the treatment. When the two species were released together, this negated the increased response to seeded traps observed in the single -species treatments. These findings suggest the potential that the presence of beetles in a trap may be influencing the response of beetles in a nearby trap and that T. castaneum and T. confusum when they occur together may influence each other's response to traps.

Metabolic byproducts resulting from protein-rich diets required for larval screwworms lead to ammonia liberation, sometimes at high levels, within the mass rearing facility. Until recently a sodium polyacrylate gel bulking agent was used for the larval media and adsorbed much of the ammonia. A need to replace the gel with an environmentally "friendly" bulking agent, while not increasing ammonia levels in the rearing facility, led to a series of experiments with the objective of developing procedures to reduce ammonia emissions from the larval media bulked with cellulose fiber. Additives of ammonia-converting bacteria, potassium permanganate, and Yucca schidigera Roezl ex Otrgies powder extract, previously reported to reduce ammonia levels in organic environments, were evaluated. Ammonia -converting bacteria did not have a positive effect. Addition of Y. schidigera powder extract (-1% of total volume), potassium permanganate (-250 ppm), and a combination of these two additives (at these same concentrations) kept ammonia at equivalent levels as when larval media was bulked with gel. Potassium permanganate also had sufficient antimicrobial properties that the use of formaldehyde in the diet was not necessary. Further testing is needed, at a mass rearing level, before full implementation into the screwworm eradication program.

TI A Biophysical and Economic Assessment of a Community-based Rehabilitated Gully in the Ethiopian Highlands SO LAND DEGRADATION & DEVELOPMENT LA English DT Article DE erosion; soil conservation; cost-benefit analysis; sediment; best management practices; Horn of Africa; East Africa ID BLUE NILE BASIN; SOIL-EROSION; NORTHERN ETHIOPIA; WATER; RATES; TECHNOLOGIES; EMPOWERMENT; MANAGEMENT; STABILITY; SEDIMENT AB Gully erosion reduces agricultural productivity by destroying valuable land resources, increases sediment concentrations, reduces water quality, and fills up reservoirs. Gully rehabilitation has proven to be challenging especially in the high-rainfall areas of the Ethiopian Highlands and has therefore had limited success. This paper describes a successful low-cost gully rehabilitation effort with community participation in the Birr watershed in the Blue Nile basin that begun in early 2013. Initially, farmers were reluctant to participate for religious reasons, but with the aid of local priests and respected elders, community discussions, and a visit to a rehabilitated gully, a consensus was reached to rehabilitate a 071-ha upland gully. The rehabilitation measures consisted of regrading the gully head at a 45 degrees slope, constructing low-cost check dams from locally available materials, and planting Pennisetum purpureum grass and Sesbania sesban. At the end of the first post-implementation rainy season, 2,200tons of soil was conserved by the constructed check dams and newly planted vegetation, compared with soil losses of 680 and 560tons in two untreated, nearby gullies. In 2014, an additional 3,100tons of soil was conserved. In 2013, the marginal rate of return (MRR) on the gully rehabilitation investment was 26 based on the value of increased forage production alone. When we include trapped soil nutrient values, the rehabilitation MRR was increased to 10. Although these numbers are impressive, the best proof of the success was that farmers on their own initiative rehabilitated an additional five gullies in 2014.

Phytotoxins produced by F. virguliforme are translocated from infected roots to leaves, in which they cause SDS foliar symptoms. In this study, additional putative phytotoxins of F. virguliforme were identified, including three secondary metabolites and 11 effectors. While citrinin, fusaric acid, and radicicol induced foliar chlorosis and wilting, Soybean mosaic virus (SMV)-mediated overexpression of F. virguliforme necrosis-inducing secreted protein 1 (FvNIS1) induced SDS foliar symptoms that mimicked the development of foliar symptoms in the field. The expression level of fvnis1 remained steady over time, although foliar symptoms were delayed compared with the expression levels. SMV::FvNIS1 also displayed genotype specific toxicity to which 75 of 80 soybean cultivars were susceptible. Genome-wide association mapping further identified three single nucleotide polymorphisms at two loci, where three leucine-rich repeat receptor-like protein kinase (LRR-RLK) genes were found. Culture filtrates of fvnis1 knockout mutants displayed a mild reduction in phytotoxicity, indicating that FvNIS1 is one of the phytotoxins responsible for SDS foliar symptoms and may contribute to the quantitative susceptibility of soybean by interacting with the LRR-RLK genes.

Citrus canker disease associated with Xanthomonas citri is one of the most important diseases damaging citrus production worldwide. In this study, we cloned the FLS2 gene from Nicotiana benthamiana cDNA and inserted it into the binary vector pBinPlus/ARS to transform Hamlin sweet orange and Carrizo citrange. Transgene presence was confirmed by polymerase chain reaction (PCR) and gene expression of NbFLS2 was compared by reverse transcription quantitative PCR. Reactive oxygen species (ROS) production in response to flg22(Xcc), was detected in transgenic Hamlin but not in nontransformed controls. Low or no ROS production was detected from nontransformed Hamlin seedlings challenged with flg22(Xcc). Transgenic plants highly expressing NbFLS2 were selected and were evaluated for resistance to canker incited by X. citri 3213. Our results showed that the integration and expression of the NbFLS2 gene in citrus can increase canker resistance and defense associated gene expression when challenged with X. citri. These results suggest that canker-susceptible Citrus genotypes lack strong basal defense induced by X. citri flagellin and the resistance of these genotypes can be enhanced by transgenic expression of the flagellin receptor from a resistant species.

Most evidence from observational, in vitro, animal model, and human studies suggests that beta-cryptoxanthin has relatively high bioavailability from its common food sources, to the extent that some beta-cryptoxanthin-rich foods might be equivalent to beta-carotene-rich foods as sources of retinol. beta-Cryptoxanthin is an antioxidant in vitro and appears to be associated with decreased risk of some cancers and degenerative diseases. In addition, many in vitro, animal model, and human studies suggest that beta-cryptoxanthin-rich foods may have an anabolic effect on bone and, thus, may help delay osteoporosis.

This article represents a critical appraisal of food parenting practices, including clear terminology and definitions, by a working group of content experts. The result of this effort was the development of a content map for future research that presents 3 overarching, higher-order food parenting constructs - coercive control, structure, and autonomy support - as well as specific practice subconstructs. Coercive control includes restriction, pressure to eat, threats and bribes, and using food to control negative emotions. Structure includes rules and limits, limited/guided choices, monitoring, meal-and snacktime routines, modeling, food availability and accessibility, food preparation, and unstructured practices. Autonomy support includes nutrition education, child involvement, encouragement, praise, reasoning, and negotiation. Literature on each construct is reviewed, and directions for future research are offered. Clear terminology and definitions should facilitate cross-study comparisons and minimize conflicting findings resulting from previous discrepancies in construct operationalization.

This group of proteins has not been well studied in Fusarium graminearum, the primary cause of Fusarium head blight (FHB), a devastating disease of wheat. We report here a comprehensive analysis of SSCPs encoded in the genome of this fungus and selection of candidate effector proteins through proteomics and sequence/transcriptional analyses. A total of 190 SSCPs were identified in the genome of F. graminearum (isolate PH-1) based on the presence of N-terminal signal peptide sequences, size (<= 200 amino acids), and cysteine content (>= 2%) of the mature proteins. Twenty-five (approximately 13%) SSCPs were confirmed to be true extracellular proteins by nanoscale liquid chromatography-tandem mass spectrometry (nanoLC-MS/MS) analysis of a minimal medium-based in vitro secretome. Sequence analysis suggested that 17 SSCPs harbor conserved functional domains, including two homologous to Ecp2, a known effector produced by the tomato pathogen Cladosporium fulvum. Transcriptional analysis revealed that at least 34 SSCPs (including 23 detected in the in vitro secretome) are expressed in infected wheat heads; about half are up-regulated with expression patterns correlating with the development of FHB. This work provides a solid candidate list for SSCP-derived effectors that may play roles in mediating F. graminearum-wheat interactions. The in vitro secretome-based method presented here also may be applicable for identifying candidate effectors in other ascomycete pathogens of crop plants.

A recently identified race, V26 with virulence to Yr26 and many other stripe rust resistance genes, has a high potential to cause epidemics in China. In this study, teliospores from a single-urediniospore isolate of V26 (Pinglan 17-7) produced on the wheat line 92R137 (Yr26) were used to produce a sexual population through selling by infecting Berberis shensiana plants under controlled conditions. One hundred and eighteen progeny isolates and the parental isolate were phenotyped for virulence/avirulence on 24 Yr gene lines of wheat. These progeny isolates were all avirulent to Yr5, Yr8, Yr15, and YrTr1 and virulent to Yr1, Yr2, Yr7, Yr9, Yr10, Yr17, Yr24, Yr25, Yr26, YrA, YrExp2, and YrV23, indicating that the parental isolate is homozygous avirulent or homozygous virulent at these loci. The progeny population segregated for avirulence to Yr6, Yr43, and YrSP at one locus (3 avirulent:1 virulent ratio); for virulence to Yr27 and Yr28 at one locus (3 virulent:1 avirulent); and for Yr4, Yr32, and Yr44 at two loci (15 virulent:1 avirulent). Among the eight segregating avirulence/virulence loci, association was found between virulence to Yr4 and Yr32, as well as between virulence to Yr6 and Yr43 based on chi(2) tests. From 82 genotypically different progeny isolates, 24 pathotypes and 82 multi locus genotypes were identified. The results show that a highly diverse population can be produced from a single isolate by selfing on a barberry plant and sexually produced population can be used to genetically characterize virulence of the stripe rust pathogen.

TI Analysis of Genetic Diversity of Fusarium tupiense, the Main Causal Agent of Mango Malformation Disease in Southern Spain SO PLANT DISEASE LA English DT Article ID FUJIKUROI SPECIES COMPLEX; GIBBERELLA-FUJIKUROI; 1ST REPORT; MANGIFERAE; OXYSPORUM; MEXICO; BRAZIL; PSEUDOCIRCINATUM; IDENTIFICATION; SUBGLUTINANS AB Mango malformation disease (MMD) has become an important global disease affecting this crop. The aim of this study was to identify the main causal agents of MMD in the Axarquia region of southern Spain and determine their genetic diversity. Fusarium nzangiferae was previously described in the Axarquia region but it represented only one-third of the fusaria recovered from malformed trees. In the present work, fusaria associated with MMD were analyzed by arbitrary primed polymerase chain reaction (ap-PCR), random amplified polymorphic DNA (RAPD), vegetative compatibility grouping (VCG), a PCR screen for mating type idiomorph, and phylogenetic analyses of multilocus DNA sequence data to identify and characterize the genetic diversity of the MMD pathogens. These analyses confirmed that 92 of the isolates were F. tupiense, which was previously only known from Brazil and Senegal. In addition, two isolates of a putatively novel MMD pathogen were discovered, nested within the African Glade of the Fusarium fujikuroi species complex. The F. tupiense isolates all belonged to VCG I, which was first described in Brazil, and the 11 isolates tested showed pathogenicity on mango seedlings. Including the prior discovery of F. mangiferae, three exotic MMD pathogenic species have been found in southern Spain, which suggests multiple independent introductions of MAID pathogens in the Axarquia region.

In the present study, 252 field isolates of M. oryzae, collected from rice fields of Yunnan Province in China, were assessed for mating type, DNA fingerprinting, and disease reactions to differential rice lines. In total, 94 isolates (37.3%) were MAT1-1 and 158 (62.7%) were MAT1-2 based on polymerase chain reaction assays, and some of them were verified with the tester isolates. All MAT1-1 and MAT1-2 isolates were virulent to some of the International Rice Research Institute Japan International Research Center for Agricultural Sciences monogenic lines harboring 22 major resistance genes as differential varieties. Three simple-sequence repeat markers were used to examine genetic diversity in all isolates. The existence of regional patterns of genetic diversity, sexual reproduction potential, and pathogenicity suggests that M. oryzae populations have been independently asexually adapted in rice fields during crop cultivation.

TI Incidence of Wheat streak mosaic virus, Triticum mosaic virus, and Wheat mosaic virus in Wheat Curl Mites Recovered from Maturing Winter Wheat Spikes SO PLANT DISEASE LA English DT Article ID HIGH-PLAINS VIRUS; DIFFERENTIAL TRANSMISSION; GREAT-PLAINS; IDENTIFICATION; POPULATIONS; VECTOR; YIELD; FIELD AB Wheat curl mites (WCM; Aceria tosichella) transmit Wheat streak mosaic virus (WSMV), Triticum mosaic virus (TriMV), and Wheat mosaic virus (WMoV) to wheat (Triticum aestivum L.) in the Great Plains region of the United States. These viruses can be detected in single, double, or triple combinations in leaf samples. Information on incidence of viruses in WCM at the end of the growing season is scant. The availability of this information can enhance our knowledge of the epidemiology of WCM-transmitted viruses. This research was conducted to determine the frequency of occurrence of WSMV, TriMV, and WMoV in WCM populations on field collected maturing wheat spikes and to determine differences in WCM densities in three geographical regions (southeast, west-central, and panhandle) in Nebraska. Maturing wheat spikes were collected from 83 fields across Nebraska in 2011 and 2012. The spikes were placed in proximity to wheat seedlings (three-to four-leaf stage) in WCM-proof cages in a growth chamber and on sticky tape. WCM that moved off the drying wheat spikes in cages infested the wheat seedlings. WCM that moved off wheat spikes placed on sticky tape were trapped on the tape and were counted under a dissecting microscope. At 28 days after infestation, the wheat plants were tested for the presence of WSMV, TriMV, or WMoV using enzyme-linked immunosorbent assay and multiplex polymerase chain reaction. WSMV was the most predominant virus detected in wheat seedlings infested with WCM from field-collected spikes. Double (TriMV+WSMV or WMoV+WSMV) or triple (TriMV+WMoV+WSMV) virus detections were more frequent (47%) than single detections (5%) of TriMV or WSMV. Overall, 81% of the wheat seedlings infested with WCM tested positive for at least one virus. No significant association (P > 0.05) was found between regions for WCM trapped on tape. These results suggest that WCM present on mature wheat spikes harbor multiple wheat viruses and may explain high virus incidence when direct movement of WCM into emerging winter wheat occurs in the fall.

To prioritize field-resistant landraces for follow-up genetic studies to test for the presence of new resistance genes, seedling response to P. graminis f. sp. tritici race TTKSK, molecular markers linked to specific Sr genes, segregation ratios among progeny from crosses, and bulked segregant analyses (BSA) were used. In total, 33 spring wheat landraces with seedling resistance to P. graminis f. sp. tritici race TTKSK were crossed to a susceptible genotype, LMPG-6. The segregation ratios of stem rust reactions in F-2 seedlings fit a single dominant gene model in 31 populations and progeny from two crosses gave ambiguous results. Using the 90K wheat single-nucleotide polymorphism genotyping platform, BSA showed that the seedling resistance in 29 accessions is probably controlled by loci on chromosome 2BL. For the three remaining accessions, BSA revealed that the seedling resistance is most likely controlled by previously unreported genes. For confirmation, two populations were advanced to the F-2:3 and screened against P. graminis f. sp. tritici race TTKSK. Segregation of the F-2:3 families fit a 1:2:1 ratio for a single dominant gene. Using the F-2:3 families, BSA located the TTKSK locus on chromosome 6DS to the same location as Sr42. C1 [Babiker, E.

With an increased need for fine temporal-scale monitoring of sensitive wetlands, we used annual Landsat MSS and TM/ETM+ images from 1972 to 2012 to manually interpret loss, gain, and type conversion of wetland area in the floodplain of the Willamette River. By creating Tasseled Cap Brightness, Greenness, and Wetness indices for MSS data that visually match TM/ETM+ Tasseled Cap images, we were able to construct a complete and consistent, annual time series and utilize the entire Landsat archive. With an extended time series we were also able to compare annual trends of net change in wetland area before and after the no-net-loss policy established under Section 404 of the Clean Water Act in 1990 using a Theil-Sen Slope estimate analysis. Vegetated wetlands experienced a 314 ha net loss of wetland area and non-vegetated wetlands experienced a 393 ha net gain, indicating higher functioning wetlands were replaced in area by non-vegetated wetland habitats such as agricultural and quarry ponds. The majority of both gain and loss in the study area was attributed to gains and losses of agricultural land. After 1990 policy implementations, the rate of wetland area lost slowed for some wetland categories and reversed into trends of gain in wetland area for others, perhaps representative of the success of increased regulations. Overall accuracy of land use classification through manual interpretation was at 80 %. This accuracy increased to 91.1 % when land use classes were aggregated to either wetland or upland categories, indicating that our methodology was more accurate at distinguishing between general upland and wetland than finer categorical classes.

TI Evaluation of economically feasible, natural plant extract-based microbiological media for producing biomass of the dry rot biocontrol strain Pseudomonas fluorescens P22Y05 in liquid culture SO WORLD JOURNAL OF MICROBIOLOGY & BIOTECHNOLOGY LA English DT Article DE Microbioreactor; Plant extract-based media; Biological control; Dry rot of potato ID POSTHARVEST DISEASES; BIOLOGICAL-CONTROL; MICROTITER PLATES; WATER ACTIVITY; GROWTH; POTATOES; EFFICACY; PH; TEMPERATURE; PERFORMANCE AB The production of microbial biomass in liquid media often represents an indispensable step in the research and development of bacterial and fungal strains. Costs of commercially prepared nutrient media or purified media components, however, can represent a significant hurdle to conducting research in locations where obtaining these products is difficult. A less expensive option for providing components essential to microbial growth in liquid culture is the use of extracts of fresh or dried plant products obtained by using hot water extraction techniques. A total of 13 plant extract-based media were prepared from a variety of plant fruits, pods or seeds of plant species including Allium cepa (red onion bulb), Phaseolus vulgaris (green bean pods), and Lens culinaris (lentil seeds). In shake flask tests, cell production by potato dry rot antagonist Pseudomonas fluorescens P22Y05 in plant extract-based media was generally statistically indistinguishable from that in commercially produced tryptic soy broth and nutrient broth as measured by optical density and colony forming units/ml produced (P <= 0.05, Fisher's protected LSD). The efficacy of biomass produced in the best plant extract-based media or commercial media was equivalent in reducing Fusarium dry rot by 50-96 % compared to controls. In studies using a high-throughput microbioreactor, logarithmic growth of P22Y05 in plant extract-based media initiated in 3-5 h in most cases but specific growth rate and the time of maximum OD varied as did the maximum pH obtained in media. Nutrient analysis of selected media before and after cell growth indicated that nitrogen in the form of NH4 accumulated in culture supernatants, possibly due to unbalanced growth conditions brought on by a scarcity of simple sugars in the media tested. The potential of plant extract-based media to economically produce biomass of microbes active in reducing plant disease is considerable and deserves further research.

Both are associated with inflammation, which may be partially triggered by oxidative stress, especially in cardiovascular disease. We investigated whether inflammatory and oxidative stress biomarkers linked to cardiovascular disease were associated with frailty and the related outcome of gait speed. We report cross-sectional associations of biomarkers and frailty assessed at Framingham Offspring Study cycle eight. Participants >= 60 years were eligible if they had information on frailty and at least one of the following: C-reactive protein, interleukin-6, tumor necrosis factor receptor 2, 8-epi-FGF alpha isoprostanes (isoprostanes), lipoprotein phospholipase A2 (LpPLA2) mass or activity, osteoprotegerin, intracellular adhesion molecule-1, monocyte chemoattractant protein-1 or P-selectin. Stepwise logistic models were utilized for frailty and stepwise linear models for gait speed. Covariates included age, sex, body mass index, smoking, and co-morbidities. Odds ratios (ORs) and slope estimates (B) are reported per standard deviation increase of loge-transformed biomarker. Of the 1919 participants, 142 (7 %) were frail. In a stepwise model, frailty odds increased with higher interleukin-6 (OR 1.90, 95 % CI 1.51, 2.38), isoprostanes (OR 1.46, 95% CI 1.12, 1.92), and LpPLA2 mass (OR 1.29, 95 % CI 1.00, 1.65). Stepwise regression found that slower gait speeds were associated with interleukin-6 (B=-0.025 m/s, 95 % CI 0.04, -0.01), isoprostanes (B=-0.019, 95 % CI -0.03, -0.008), LpPLA2 mass (B=-0.016, 95 % CI -0.03, -0.004), and osteoprotegerin (B = -0.015, 95 % CI -0.03, -0.002, all p< 0.05). Interleukin-6, isoprostanes, and LpPLA2 mass were associated with greater frailty odds and slower gait speeds. Oxidative stress may be a mechanism contributing to frailty.

TI Energy dissipation in intercalated carbon nanotube forests with metal layers SO APPLIED PHYSICS A-MATERIALS SCIENCE & PROCESSING LA English DT Article ID MECHANICAL-PROPERTIES; COMPOSITES; GROWTH; ARRAYS; WIRES; TIPS AB Vertically aligned carbon nanotube (CNT) forests were synthesized to study their quasi-static mechanical properties in a layered configuration with metallization. The top and bottom surfaces of CNT forests were metalized with Ag, Fe, and In using paste, sputtering, and thermal evaporation, respectively. Stacks of one, two, and three layers of these forests were assembled and compressed to measure their mechanical properties. The samples were strain limited to 0.7, and the results indicate that energy dissipation is approximately linear with respect to the number of layers and relatively independent of metal type. The energy per unit volume was approximately the same for all samples. Successive stacking of CNT forests reduces local buckling events, which is enhanced with a thick Ag deposition on the CNT forest surface. Young's modulus was also observed to increase as the number of layers was increased. These results are useful in the design of composite materials for high energy absorption and high stiffness applications.

A native of Australia, Papua New Guinea, and the Solomon Islands, the brown treesnake (BTS) continues to threaten the economy and ecology of Guam and is currently the subject of a cooperative program to control snake populations on the island and prevent its spread throughout the Pacific Rim. Delivery of toxic baits is a primary component of population suppression efforts. While many food items tested as baits for toxicant delivery provide relevant food prey cues leading to investigatory behaviors in BTS, only a few items tested in the past two decades have adequately promoted reliable consumption. Chief among them is the dead neonatal mouse (DNM). A series of chemical and bioassays were performed to identify materials with similar sensory qualities as DNM. Among the many items tested in a series of field experiments with free-ranging BTS in Guam, a processed meat product treated with an artificial mouse fat mixture was found to be removed from bait stations at rates greater than previously tested DNM substitutes and approaching removal rates of DNM. Furthermore, the test baits demonstrated excellent durability under field conditions. Further development of this bait offers great potential to satisfy many desirable attributes for BTS baiting operations.

Over the past two decades, this condition, known as thousand cankers disease (TCD), has led to the widespread mortality of Juglans species in the United States of America. Recently the beetle and pathogen were discovered on several Juglans species in northern Italy. Little is known about the extra-generic extent of host acceptability and suitability for the WTB. We report the occurrence of both the WTB and G. morbida in three species of wingnut, Pterocarya fraxinifolia Spach, Pterocarya rhoifolia Siebold and Zuccarini, and Pterocarya stenoptera de Candolle (Juglandaceae) growing in the United States Department of Agriculture-Agricultural Research Service, National Clonal Germplasm Repository collection in northern California (NCGR) and in the Los Angeles County Arboretum and Botanic Garden in southern California, United States of America. In two instances (once in P. stenoptera and once in P. fraxinifolia) teneral (i.e., brood) adult WTB emerged and were collected more than four months after infested branch sections had been collected in the field. Koch's postulates were satisfied with an isolate of G. morbida from P. stenoptera, confirming this fungus as the causal agent of TCD in this host. A survey of the 37 Pterocarya Kunth accessions at the NCGR revealed that 46% of the trees had WTB attacks and/or symptoms of G. morbida infection. The occurrence of other subcortical Coleoptera associated with Pterocarya and the first occurrence of the polyphagous shot hole borer, a species near Euwallacea fornicatus Eichhoff (Coleoptera: Curculionidae), in Juglans are also documented.

This paper investigates a multistage stochastic mixed integer program with full recourse to model spatially explicit fire behavior and to select suppression locations for a wildland fire. Simplified suppression decisions take the form of "suppression nodes", which are placed on a raster landscape for multiple decision stages. Weather scenarios are used to represent a distribution of probable changes in fire behavior in response to random weather changes, modeled using probabilistic weather trees. Multistage suppression decisions and fire behavior respond to these weather events and to each other. Nonanticipativity constraints ensure that suppression decisions account for uncertainty in weather forecasts. Test cases for this model provide examples of fire behavior interacting with suppression to achieve a minimum expected area impacted by fire and suppression.

Using data from 1465 forest inventory plots, we estimated probability of occurrence and basal area of six common conifer species across three broad latitudinal regions of coastal Alaska. By also comparing models across life stages of each species (seedlings, saplings, mature trees, and dead trees), we explored trends in population stability at this leading edge of climate change. Elevation had a stronger influence on the probability of tree species occurrence than on basal area; site productivity impacted both estimated odds of presence and estimated basal area for most species in at least some regions. Interestingly, there were fairly dramatic differences across species in the degree to which the modeled probability of occurrence differed across the four life stages. Western redcedar (Thuja plicata Donn ex D. Don), for example, showed relatively stable distributions but other species appear to be in flux, e.g., yellow-cedar (Callitropsis nootkatensis (D. Don) D. P. Little), which has experienced widespread mortality at low elevations. Differential effects of elevation on live versus dead basal area suggest that mountain hemlock (Tsuga mertensiana (Bong.) Carriere) and yellow-cedar are shifting upslope in some regions and that Sitka spruce (Picea sitchensis (Bong.) Carriere) is shifting downslope in the Northwest region. C1 [Caouette, J.

This paper compares the Generator for Point Climate Change (GPCC) model and the Statistical DownScaling Model (SDSM)-two contrasting SD methods-in terms of their ability to generate precipitation series under non-stationary conditions across ten contrasting global climates. The mean, maximum and a selection of distribution statistics as well as the cumulative frequencies of dry and wet spells for four different temporal resolutions were compared between the models and the observed series for a validation period. Results indicate that both methods can generate daily precipitation series that generally closely mirror observed series for a wide range of non-stationary climates. However, GPCC tends to overestimate higher precipitation amounts, whilst SDSM tends to underestimate these. This infers that GPCC is more likely to overestimate the effects of precipitation on a given impact sector, whilst SDSM is likely to underestimate the effects. GPCC performs better than SDSM in reproducing wet and dry day frequency, which is a key advantage for many impact sectors. Overall, the mixed performance of the two methods illustrates the importance of users performing a thorough validation in order to determine the influence of simulated precipitation on their chosen impact sector.

TI Patterns of hybridization among cutthroat trout and rainbow trout in northern Rocky Mountain streams SO ECOLOGY AND EVOLUTION LA English DT Article DE cutthroat; hybridization; Oncorhynchus; SNP; swarm ID ONCORHYNCHUS-CLARKII-LEWISI; ENDANGERED SPECIES ACT; SOUTHEASTERN BRITISH-COLUMBIA; HYBRID ZONE STRUCTURE; WESTSLOPE CUTTHROAT; INTROGRESSIVE HYBRIDIZATION; GENETIC IDENTIFICATION; SPAWNING HABITAT; RIVER DRAINAGE; SALMO-CLARKI AB Introgressive hybridization between native and introduced species is a growing conservation concern. For native cutthroat trout and introduced rainbow trout in western North America, this process is thought to lead to the formation of hybrid swarms and the loss of monophyletic evolutionary lineages. Previous studies of this phenomenon, however, indicated that hybrid swarms were rare except when native and introduced forms of cutthroat trout co-occurred. We used a panel of 86 diagnostic, single nucleotide polymorphisms to evaluate the genetic composition of 3865 fish captured in 188 locations on 129 streams distributed across western Montana and northern Idaho. Although introgression was common and only 37% of the sites were occupied solely by parental westslope cutthroat trout, levels of hybridization were generally low. Of the 188 sites sampled, 73% contained 5% rainbow trout alleles and 58% had 1% rainbow trout alleles. Overall, 72% of specimens were nonadmixed westslope cutthroat trout, and an additional 3.5% were nonadmixed rainbow trout. Samples from seven sites met our criteria for hybrid swarms, that is, an absence of nonadmixed individuals and a random distribution of alleles within the sample; most (6/7) were associated with introgression by Yellowstone cutthroat trout. In streams with multiple sites, upstream locations exhibited less introgression than downstream locations. We conclude that although the widespread introduction of nonnative trout within the historical range of westslope cutthroat trout has increased the incidence of introgression, sites containing nonadmixed populations of this taxon are common and broadly distributed.

A major Al tolerance locus on chromosome 3, Alt(SB), controls aluminum tolerance in sorghum [Sorghum bicolor (L.) Moench] via SbMATE, an Al-activated plasma membrane transporter that mediates Al exclusion from sensitive regions in the root apex. As is the case with other known Al tolerance genes, SbMATE was cloned based on studies conducted under controlled environmental conditions, in nutrient solution. Therefore, its impact on grain yield on acid soils remains undetermined. To determine the real world impact of SbMATE, multi-trait quantitative trait loci (QTL) mapping in hydroponics, and, in the field, revealed a large-effect QTL colocalized with the Al tolerance locus AltSB, where SbMATE lies, conferring a 0.6 ton ha(-1) grain yield increase on acid soils. A second QTL for Al tolerance in hydroponics, where the positive allele was also donated by the Al tolerant parent, SC283, was found on chromosome 9, indicating the presence of distinct Al tolerance genes in the sorghum genome, or genes acting in the SbMATE pathway leading to Al-activated citrate release. There was no yield penalty for AltSB, consistent with the highly localized Al regulated SbMATE expression in the root tip, and Al-dependent transport activity. A female effect of 0.5 ton ha(-1) independently demonstrated the effectiveness of AltSB in hybrids. Al tolerance conferred by AltSB is thus an indispensable asset for sorghum production and food security on acid soils, many of which are located in developing countries.

Traits conferring organophosphate insecticide resistance have increased in frequency amongst D. v. virgifera populations, resulting in the reduced efficacy in many corn-growing regions of the USA. We used comparative functional genomic and quantitative trait locus (QTL) mapping approaches to investigate the genetic basis of D. v. virgifera resistance to the organophosphate methyl-parathion. RNA from adult methyl-parathion resistant and susceptible adults was hybridized to 8331 microarray probes. The results predicted that 11 transcripts were significantly up-regulated in resistant phenotypes, with the most significant (fold increases >= 2.43) being an alpha-esterase-like transcript. Differential expression was validated only for the alpha-esterase (ST020027A20C03), with 11- to 13-fold greater expression in methyl-parathion resistant adults (P < 0.05). Progeny with a segregating methylparathion resistance trait were obtained from a reciprocal backcross design. QTL analyses of high-throughput single nucleotide polymorphism genotype data predicted involvement of a single genome interval. These data suggest that a specific carboyx-esterase may function in field-evolved corn rootworm resistance to organophosphates, even though direct linkage between the QTL and this locus could not be established.

TI How climate change has affected the spatio-temporal patterns of precipitation and temperature at various time scales in North Korea SO INTERNATIONAL JOURNAL OF CLIMATOLOGY LA English DT Article DE climate change; spatial structure; correlation matrix; precipitation; temperature; North Korea ID TEMPORAL TRENDS; VARIABILITY; REGIME AB Detecting changes in the spatio-temporal patterns of temperature and precipitation is a prerequisite for developing effective adaptation options and strategies for the future. An effective method for assessing climate change and for providing information to decision makers and stakeholders is needed to implement appropriate adaptation strategies. The objective of this study was to determine whether climate change has caused spatio-temporal changes in meteorological elements in North Korea. We delineated the spatio-temporal patterns of temperature and precipitation caused by climate change in specific time periods based on statistically significant differences using a statistically robust method. Historical weather data from 27 meteorological stations over a 30-year period (1981-2010) were used. The results demonstrated that statistically significant changes occurred over the 30 years. The temporal trends in the maximum and minimum temperatures were highly significantly different in the western agricultural regions and central/southwest urban regions during 1996-2010 compared with 1981-1995. The precipitation amounts were significantly different in the southeast regions (around the coast). The numbers of precipitation events were significantly different for portions of the northern and northeast areas near the mountains. Additionally, statistically significant differences in the spatial structures of the temperature and precipitation were found at different time scales. The significant differences were not uniform in each season/month. Therefore, significant differences occurred in the meteorological elements, and particular locations and urbanized areas were affected by global warming. However, the temporal trends and spatial structures of each meteorological element were not equally modified; the meteorological changes occurred locally as a result of the changing climate.

Cenovus Energy Inc. operates more than 1000 active wells, processing plants, and hundreds of kilometres of pipeline infrastructure over a >100 km(2) area. While vehicle-based atmospheric detection of gas leakage would be convenient for a distributed operation such as Weyburn, implementing atmospheric detection schemes, particularly those that target CO2, are challenging in that natural ecosystems and other human activities both emit CO2 and will contribute to regular false positives. Here we present field test results of a multi-gas atmospheric detection technique that uses observed trace gas ratios (CO2, CH4, and H2S) to discriminate plumes of gas originating from different sources. This work is part of a larger project focused on multi-scale fugitive emissions detection and plume discrimination. During 2013 and 2014, we undertook vehicle-based mobile surveys of CO2, CH4, H2S, and delta(CH4)-C-13, in the Weyburn oilfield, using customized Cavity Ring Down Spectroscopy (CRDS) instruments that also alternated as stationary receptors. Mobile surveys provided georeferenced observations of atmospheric gas concentrations every 20-30 m, along a route driven at roughly 70 km h(-1). Data were uploaded to remote servers and processed using visualization tools that allowed us to constrain the location and timing of potential emission events. Results from one day of mobile surveying, September 24,2013, are presented here to illustrate how industrial activities, combustion engine and flare stack source emissions can be discriminated on the basis of excess mixing gas ratios, at distances from a few hundreds metres, to kilometres, in the Weyburn oilfield.

The composites were prepared in a compression mold at 130 degrees C, with 20% starch content. An amylose-free cornstarch, waxy maize, was used for this research, and the heat treatment range was from ambient temperature to 170 degrees C. The heat-treated starch (HTS) was characterized by optical microscopy, dynamic light scattering, and size exclusion chromatography. The composites were characterized by mechanical analysis (stress-strain) and by scanning electron microscopy. The mechanical tests of composites revealed a dramatic increase in the modulus and tensile strength when the gelatinized starch was incorporated. When the starch was not gelatinized, starch did not contribute to the increase in the modulus and tensile strength because of its small surface area, thus weak interaction with the matrix. The reinforcing effect of starch as filler was reduced as the heating temperature of starch was increased to higher than 120 degrees C. The variation of reinforcement effect of HTS as filler was explained by the interaction between starch and matrix material, latex.

TI Prevalence of Nontyphoidal Salmonella and Salmonella Strains with Conjugative Antimicrobial-Resistant Serovars Contaminating Animal Feed in Texas SO JOURNAL OF FOOD PROTECTION LA English DT Article DE Animal feed; Antimicrobial resistance; Feed ingredients; Preharvest food safety; Salmonella ID ESCHERICHIA-COLI; UNITED-STATES; MULTIDRUG-RESISTANT; FOODBORNE ILLNESS; DRUG-RESISTANCE; RISK-FACTORS; PLASMIDS; ENTERICA; SUSCEPTIBILITY; INGREDIENTS AB The objective of this study was to characterize 365 nontyphoidal Salmonella enterica isolates from animal feed. Among the 365 isolates, 78 serovars were identified. Twenty-four isolates (7.0%) were recovered from three of six medicated feed types. Three of these isolates derived from the medicated feed, Salmonella Newport, Salmonella Typhimurium var. O 5-(Copenhagen), and Salmonella Lexington var. 15+ (Manila), displayed antimicrobial resistance. Susceptibility testing revealed that only 3.0% (12) of the 365 isolates displayed resistance to any of the antimicrobial agents. These 12 isolates were recovered from unmedicated dry beef feed (n = 3), medicated dry beef feed (n = 3), cabbage culls (n = 2), animal protein products (n = 2), dry dairy cattle feed (n = 1), and fish meal (n = 1). Only Salmonella Newport and Salmonella Typhimurium var. O 5-(Copenhagen) were multidrug resistant. Both isolates possessed the IncA/C replicon and the bla(CMY-2) gene associated with cephalosporin resistance. Plasmid replicons were amplified from 4 of 12 resistant isolates. Plasmids (40 kb) were Salmonella Montevideo and Salmonella Kentucky. Conjugation experiments were done using 7 of the 12 resistant isolates as donors. Only Salmonella Montevideo, possessing a plasmid and amplifying IncN, produced transconjugants. Transconjugants displayed the same antimicrobial resistance profile as did the donor isolate. Three isolates that amplified replicons corresponding to IncA/C or IncHI2 did not produce transconjugants at 30 or 37 degrees C. The results of this study suggest that the prevalence of antimicrobial-resistant Salmonella contaminating animal feed is low in Texas. However, Salmonella was more prevalent in feed by-products; fish meal had the highest prevalence (84%) followed by animal protein products (48%). Ten of the 35 feed types had no Salmonella contamination. Further investigation is needed to understand the possible role of specific feed types in the dissemination of antimicrobial resistant bacteria.

TI In Vitro Effects of Thymol-beta-D-Glucopyranoside on Salmonella enterica Serovar Typhimurium and Escherichia coli K88 SO JOURNAL OF FOOD PROTECTION LA English DT Article DE Escherichia coli; Intervention methods; Salmonella; beta-Thymol ID DIPHENYLIODONIUM CHLORIDE; ANTIMICROBIAL ACTIVITY; TRANS-CINNAMALDEHYDE; ESSENTIAL OILS; GUT BACTERIA; CAMPYLOBACTER; CARVACROL; OUTBREAK; EUGENOL; PIGLETS AB Although thymol is bactericidal against many pathogens in vitro, its in vivo effectiveness against pathogens in the lower gastrointestinal tract is limited because of its rapid absorption in the proximal gut. Thymol-beta-D-glucopyranoside (beta-thymol), a conjugated form of thymol, can deliver thymol to the lower gastrointestinal tract and has shown antibacterial effects. In the present study, we examined the in vitro effects of beta-thymol on Salmonella enterica serovar Typhimurium (ST) and Escherichia coli K88 (K88). We inoculated one-half strength Mueller-Hinton broth with 5.8 +/- 0.09 log CFU/ml novobiocin- and naladixic acid-resistant (NN) ST (NVSL 95-1776) and 5.1 +/- 0.09 log CFU ml(-1) NN-resistant K88, with or without porcine feces (0.1% [wt/vol]) (fecal incubations). The resultant bacterial suspensions were distributed under N-2 to triplicate sets of tubes to achieve initial concentrations of 0, 3, 6, and 12 mM for ST treatments and 0, 3, 12, and 30 mM for K88 treatments. Samples were incubated at 39 degrees C and then plated onto NN-containing brilliant green agar and NN-containing MacConkey agar; ST and K88 CFU concentrations were determined via 10-fold dilutions, and viable cell counts were performed at 0, 6, and 24 h. No differences in ST CFU counts were observed in beta-thymol treated tubes without the added porcine feces (i.e., pure culture) at 6 or 24 h. However, in tubes that contained fecal incubations, ST CFU counts were reduced (P < 0.05) from controls at 6 h in tubes treated with 6 and 12 mM beta-thymol, whereas in tubes treated with 3, 6, and 12 mM beta-thymol the CFU counts were reduced (P < 0.05) at 24 h. No differences were observed in K88 CFU counts in pure culture or in fecal incubations at 6 h, but K88 CFU counts were reduced (P < 0.05) in both pure and fecal incubations at 24 h. The results from this study demonstrate that beta-thymol, in the presence of fecal suspensions, has anti-Salmonella and anti-E. coli effects, suggesting a role of beta-glycoside-hydrolyzing microbes for the release of bactericidal thymol from beta-thymol.

TI Hydrogeologic influence on changes in snowmelt runoff with climate warming: Numerical experiments on a mid-elevation catchment in the Sierra Nevada, USA SO JOURNAL OF HYDROLOGY LA English DT Article DE streamflow; Runoff; Snow; Climate warming; Hydrogeology; Hydrologic property ID WESTERN UNITED-STATES; SOIL-WATER STORAGE; SENSITIVITY-ANALYSIS; STREAMFLOW RESPONSE; ALPINE VEGETATION; CHANGE SCENARIOS; RIVER-BASINS; CALIFORNIA; FOREST; MODELS AB The role of hydrogeology in mediating long-term changes in mountain streamflow, resulting from reduced snowfall in a potentially warmer climate, is currently not well understood. We explore this by simulating changes in stream discharge and evapotranspiration from a mid-elevation, 1-km(2) catchment in the southern Sierra Nevada of California (USA) in response to reduced snowfall under warmer conditions, for a plausible range in subsurface hydrologic properties. Simulations are performed using a numerical watershed model, the Penn State Integrated Hydrologic Model (PIHM), constrained by observations from a meteorological station, stream gauge, and eddy covariance tower. We predict that the fraction of precipitation occurring as snowfall would decrease from approximately 47% at current conditions to 25%, 12%, and 5% for air temperature changes of +2, +4, and +6 degrees C. For each of these warming scenarios, changes in mean annual discharge and evapotranspiration simulated by the different plausible soil models show large ranges relative to averages, with coefficients of variation ranging from -3 to 3 depending on warming scenario. With warming and reduced snowfall, substrates with greater storage capacity show less soil moisture limitation on evapotranspiration during the late spring and summer, resulting in greater reductions in annual stream discharge. These findings indicate that the hydrologic response of mountain catchments to atmospheric warming and reduced snowfall may substantially vary across elevations with differing soil and regolith properties, a relationship not typically accounted for in approaches relying on space-for-time substitution, An additional implication of our results is that model simulations of annual stream discharge in response to snowfall-to-rainfall transitions may be relatively uncertain for study areas where subsurface properties are not well constrained.

The Water Erosion Prediction Project (WEPP) has the ability to model disturbed forested hillslopes, but has difficulty addressing some of the critical processes that are important at a watershed scale, including baseflow and water yield. In order to apply WEPP to forested watersheds, we developed and assessed new approaches for simulating streamflow and sediment transport from large watersheds using WEPP. We created specific algorithms to spatially distribute soil, climate, and management input files for all the subwatersheds within the basin. The model enhancements were tested on five geologically and climatically diverse watersheds in the Lake Tahoe basin, USA. The model was run with minimal calibration to assess WEPP's ability as a physically-based model to predict streamflow and sediment delivery. The performance of the model was examined against 17 years of observed snow water equivalent depth, stream flow, and sediment load data. Only region-wide baseflow recession parameters related to the geology of the basin were calibrated with observed streamflow data. Close agreement between simulated and observed snow water equivalent, streamflow, and the distribution of fine (<20 mu m) and coarse (>20 mu m) sediments was achieved at each of the major watersheds located in the high-precipitation regions of the basin. Sediment load was adequately simulated in the drier watersheds; however, annual streamflow was overestimated. With the exception of the drier eastern region, the model demonstrated no loss in accuracy when applied without calibration to multiple watersheds across Lake Tahoe basin demonstrating the utility of the model as a management tool in gauged and ungauged basins.

TI Transcriptional, translational, and physiological signatures of undernourished honey bees (Apis mellifera) suggest a role for hormonal factors in hypopharyngeal gland degradation SO JOURNAL OF INSECT PHYSIOLOGY LA English DT Article DE Apis mellifera; Nutrition; Hypopharyngeal gland ID PROGRAMMED CELL-DEATH; DIVISION-OF-LABOR; DROSOPHILA-MELANOGASTER; SALIVARY-GLANDS; CALLIPHORA-VOMITORIA; EXPRESSION ANALYSIS; AMBLYOMMA-HEBRAEUM; ECDYSTEROID TITER; IXODID TICK; L. COLONIES AB Honey bee colonies function as a superorganism, where facultatively sterile female workers perform various tasks that support the hive. Nurse workers undergo numerous anatomical and physiological changes in preparation for brood rearing, including the growth of hypopharyngeal glands (HGs). These glands produce the major protein fraction of a protein-and lipid-rich jelly used to sustain developing larvae. Pollen intake is positively correlated with HG growth, but growth in the first three days is similar regardless of diet, suggesting that initial growth is a pre-determined process while later HG development depends on nutrient availability during a critical window in early adulthood (>3 d). It is unclear whether the resultant size differences in nurse HG are simply due to growth arrest or active degradation of the tissue. To determine what processes cause such differences in HG size, we catalogued the differential expression of both gene transcripts and proteins in the HGs of 8 d old bees that were fed diets containing pollen or no pollen. 3438 genes and 367 proteins were differentially regulated due to nutrition. Of the genes and proteins differentially expressed, undernourished bees exhibited more gene and protein up-regulation compared to well-nourished bees, with the affected processes including salivary gland apoptosis, oogenesis, and hormone signaling. Protein secretion was virtually the only process up-regulated in well-nourished bees. Further assays demonstrated that inhibition of ultraspiracle, one component of the ecdysteroid receptor, in the fat body caused larger HGs. Undernourished bees also had higher acid phosphatase activity, a physiological marker of cell death, compared to well-nourished bees. These results support a connection between poor nutrition, hormonal signaling, and HG degradation. Published by Elsevier Ltd. C1 [Corby-Harris, Vanessa; Meador, Charlotte A.

One of 2 remnant populations of fishers in California is in the southern Sierra Nevada region, where we studied them at 2 research sites in the Sierra National Forest. Our objectives were to evaluate whether survival was lower for male fishers and dispersal-aged individuals or if survival varied seasonally. We captured and monitored 232 radiocollared fishers from March 2007 to March 2014 and used model analyses to identify important predictors of survival. Fifty-two percent (n = 120) of the radiocollared fishers died, and survival varied by sex and season, but not by age or between study sites. There was no evidence that dispersal-aged fishers experienced lower survival than older fishers. Annual survival trended lower for male (0.62 [95% CI 0.54-0.70]) compared to female fishers (0.72 [95% CI 0.67-0.78]), was lowest in the spring to mid-summer season (0.83 [95% CI 0.78-0.87]), and highest in late fall and winter (0.92 [95% CI 0.89-0.94]). Lower survival among male fishers appeared linked to males moving over large areas to locate mates, while lower survival for females was potentially related to high energetic cost of reproduction. It was possible but unknown if lower survival among all fishers in spring was linked to secondary exposure to toxicants dispersed around illicit marijuana grow sites. Six-month survival of juvenile fishers was 0.85 for females and 0.79 for males, but lower at 0.62 for females and 0.57 for males when adjusted for deaths before late September. Annual survival among adult female fishers was 20% lower than 0.90, a value that prior modeling suggested was required for population expansion in the overall southern Sierra Nevada. Survival data from our study imply a greater challenge for maintaining self-sustaining fisher populations in the southern Sierra Nevada region, and resource managers are working to mitigate several of the human-associated factors that limit population growth.

As we may not have the full knowledge of these confounding factors, conventional statistical meta-analysis methods can be misleading. We discuss the use of two statistical causal analysis methods for quantifying the effects of water and soil conservation practices in reducing P loss from agricultural fields. With the propensity score method, a subset of data was used to form a treatment group and a control group with similar distributions of confounding factors. With the multilevel modeling method, data were stratified based on important confounding factors, and the conservation practice effect was evaluated for each stratum. Both methods resulted in similar estimates of the conservation practice effect (total P load reduction avg. similar to 70%). In addition, both methods show evidence of conservation practices reducing the incremental increase in total P export per unit increase in fertilizer application. These results are presented as examples of the types of outcomes provided by statistical causal analyses, not to provide definitive estimates of P loss reduction. The enhanced meta-analysis methods presented within are applicable for improved assessment of agricultural practices and their effects and can be used for providing realistic parameter values for watershed-scale modeling.

Process-based models like SWAT require a great deal of data to accurately represent the natural world, including topography, land use, soils, weather, and management. With the exception of management, all these data are available nationally from multiple sources. To date, credible SWAT studies in the U.S. have assembled suitable management data (operation scheduling, fertilization application rates, and plant growth parameterization). In this research, we develop a national management database for SWAT using existing U.S. Department of Agriculture data sources. These data are compatible with existing SWAT interfaces and are relatively easy to use. Although management data from local sources is preferred, these data are not always available. This work is intended to fill this void with more reasonable management data than the existing defaults. This national database covers all major cultivated crops and should facilitate improved SWAT applications in the U.S. These data were tested in two case studies and found to produce satisfactory SWAT predictions. The database developed in this research is freely available on the web. C1 [White, Michael; Gambone, Marilyn] ARS, USDA, 808 E Blackland Rd, Temple, TX 76502 USA.

Understanding factors that influence detection probabilities will allow managers to more accurately estimate the number of males present on leks. We fitted 410 males with global positioning system and very high frequency transmitters, and uniquely identifiable leg-bands over 4 years in Carbon County, Wyoming. We counted male sage-grouse using commonly used lek-count protocols and evaluated variables associated with our ability to detect marked males using sightability surveys on 22 leks. We evaluated detection probabilities of male sage-grouse based on factors related to bird characteristics such as age or posture, lek and group size, lek characteristics such as vegetation cover or aspect, light conditions, weather, and observer. We then applied the detection probabilities to more accurately estimate male counts on leks. Detection probabilities were generally high (x=0.87) but varied among leks from 0.77 to 0.93. Male sage-grouse detection declined with increasing sagebrush height and bare ground and increased with more snow cover. Detection probabilities were also lower when observers counted from a higher elevation than the lek. Our sightability models predicted detection well and can be used to accurately estimate male abundance on leks from lek counts, which is especially useful where accurate abundance estimates are required or inference about population status is based on only 1 count. Further, it is important to consider lek attendance as a component of counts on leks because it affects availability of male sage-grouse for detection during lek counts. Detection can be maximized by conducting lek counts from 30minutes before sunrise to 30minutes after sunrise, although current protocols recommend lek counts can be performed up to 1hour after sunrise. Detection can also be maximized by conducting lek counts 2 days after snowfall, which maximizes attendance and detection. (c) 2015 The Wildlife Society.

We applied a rapid field protocol to a DNA-based, mark-recapture approach on a large and tightly bounded sample frame to estimate brown bear abundance. We used lure to attract bears to barbed wire stations deployed in 145 9-kmx9-km cells systematically distributed across 10,200km(2) of available habitat on the Kenai National Wildlife Refuge and Chugach National Forest during 31 consecutive days in early summer 2010. Using 2 helicopters and 4 2-person field crews, we deployed the stations during a 6-day period and subsequently revisited these stations on 5 consecutive 5-day trap sessions. We extracted DNA to identify individual bears and developed capture histories as input to mark-recapture models. Combined with data from radio-telemetered bears, 243 brown bears were alive on the Kenai Peninsula in 2010, but we used only 99 females and 104 males in modeling. We used Akaike's Information Criterion selection and model averaging to estimate 428 (95% lognormal CI=353-539) brown bears (including all age classes) on the study area. Despite low recaptures rates, we achieved reasonable precision by ensuring geographic and demographic population closure through a spatially comprehensive sample frame and very short sampling window. We reduced bias by including information from rub trees and telemetered females (i.e., occasion 0). Extrapolating the density estimate of 42 bears/1,000 km(2) of available habitat on the study area to the Kenai Peninsula suggests a peninsula-wide population of 582 brown bears (95% lognormal CI=469-719). Despite a density estimate that is low compared to other coastal brown bear populations in Alaska and genetic evidence that suggests this peninsular population is insular, harvest management has been liberalized since 2012. We recommend this population estimate serve as the benchmark for future management. Published 2015. This article is a U.S. Government work and is in the public domain in the USA.

TI Impact of heat stress during seed development on soybean seed metabolome SO METABOLOMICS LA English DT Article DE Soybean; Seed development; Antioxidants; Germination; Abiotic stress ID MASS-SPECTROMETRY; GENETIC DIVERSITY; HIGH-TEMPERATURE; PROTEIN-CONTENT; ASCORBIC-ACID; ANTIOXIDANT; YIELD; IDENTIFICATION; CULTIVARS; PLANTS AB Seed development is a temperature-sensitive process that is much more vulnerable than vegetative tissues to abiotic stresses. High temperatures during soybean (Glycine max) seed development frequently results in seed with poor germination, increased incidence of pathogen infection, and decreased economic value. Climate change is expected to increase the incidence and severity of summer heatwaves, and the impact of heat stress on seed development will become more widespread during the course of the twenty-first century. Global metabolite profiles were contrasted between seed from heat-tolerant and heat-susceptible genotypes produced under 28/22 degrees C (control), 36/24 degrees C, and 42/26 degrees C day/night temperatures. Germination of seeds from the heat-susceptible genotype was strongly reduced (50 %) for the 36/24 degrees C treatment and completely inhibited for the 42/26 degrees C. In contrast, germination was unaffected for the heat-tolerant genotype for the 36/24 degrees C, and while strongly inhibited, some (25 %) seed from the heat-tolerant genotype were able to germinate even for the 42/26 degrees C treatment, and in general were less impacted by elevated temperatures as compared to a commonly grown high-yielding, but heat-sensitive genotype. A total of 275 seed metabolites were analyzed by three metabolite profiling methods, and genotype-specific differences and temperature specific differences were identified. A diverse set of antioxidant metabolites, including tocopherols, flavonoids, phenylpropanoids, and ascorbate precursors were found to be enriched in seed of the heat tolerant genotype. The generally greater abundance of these metabolites at both temperatures in the tolerant genotype indicates that these compounds are likely responsible, at least in part, for the greater tolerance to high temperatures during seed development.

We aimed to conduct an integrated analysis with both population and in vitro studies to systematically explore the relationships among n-3 PUFA, DNA methylation, single nucleotide polymorphisms (SNPs), gene expression, and protein concentration of IL6. Methods and resultsUsing data in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) study and the Encyclopedia of DNA Elements (ENCODE) consortium, we found that higher methylation of IL6 promoter cg01770232 was associated with higher IL-6 plasma concentration (p = 0.03) and greater IL6 gene expression (p = 0.0005). Higher circulating total n-3 PUFA was associated with lower cg01770232 methylation (p = 0.007) and lower IL-6 concentration (p = 0.02). Moreover, an allele of IL6 rs2961298 was associated with higher cg01770232 methylation (p = 2.55x10(-7)). The association between n-3 PUFA and cg01770232 methylation was dependent on rs2961298 genotype (p = 0.02), but higher total n-3 PUFA was associated with lower cg01770232 methylation in the heterozygotes (p = 0.04) not in the homozygotes. ConclusionHigher n-3 PUFA is associated with lower methylation at IL6 promoter, which may be modified by IL6 SNPs.

Predation by Orius spp. was studied in a lettuce plot by conventional polymerase chain reaction (PCR) and real-time PCR analyses using specific primers of both main pests. Also, high-throughput sequencing was used to have a wider approach of the diet of these predators in natural field conditions. RESULTS: Molecular analyses indicated a higher predation on N. ribisnigri in spring and on F. occidentalis in summer. Predation on alternative prey, like Collembola, was also found in both seasons. Real-time PCR was more sensitive than conventional PCR in showing the target trophic links, whereas high-throughput sequencing revealed predation on other natural enemies - intraguild predation (IGP), showing other trophic interactions of Orius majusculus within the studied ecosystem. CONCLUSIONS: This study gives important information about the trophic relationships present in Mediterranean lettuce crops in different periods of the year. The detected predation by Orius spp. on alternative prey, as well as on other natural enemies, should be further investigated to clarify whether it adds or detracts to the biological control of N. ribisnigri and F. occidentalis.

TI Fumigation efficacy and emission reduction using low-permeability film in orchard soil fumigation SO PEST MANAGEMENT SCIENCE LA English DT Article DE 1,3-dichloropropene; chloropicrin; fumigant application; methyl bromide; nematode; Phytophthora; shank injection; soil fumigation; weed ID PERENNIAL CROP NURSERIES; METHYL-BROMIDE; CHLOROPICRIN EMISSIONS; VAPOR SAFE; 1,3-DICHLOROPROPENE; TIF; ALTERNATIVES; DENSITIES; FUMIGANTS; MEDIA AB BACKGROUND: Many orchards use fumigation to control soilborne pests prior to replanting. Controlling emissions ismandatory to reduce air pollution in California. This research evaluated the effects of plastic film type [polyethylene (PE) or totally impermeable film (TIF)], application rate of Telone C35 [full (610 kg ha(-1)), 2/3 or 1/3 rates] and carbonation at 207 kPa on fumigant transport (emission and in soil) and efficacy. RESULTS: While increasing fumigant concentrations under the tarp, TIF reduced emissions >95%(similar to 2% and <1% of total applied 1,3-dichloropropene and chloropicrin respectively) relative to bare soil, compared with similar to 30% reduction by PE. All fumigation treatments, regardless of film type, provided good nematode control above 100 cm soil depth; however, nematode survival was high at deeper depths. Weed emergence was mostly affected by tarping and fumigant rate, with no effects from the carbonation. CONCLUSION: TIF can effectively reduce fumigant emissions. Carbonation under the studied conditions did not improve fumigant dispersion and pest control. The 2/3 rate with TIF controlled nematodes as effectively as the full rate in bare soil or under the PE film to 100 cm soil depth. However, control of nematodes in deeper soil remains a challenge for perennial crops. Published 2015. This article is a U.S. Government work and is in the public domain in the USA.

To obtain the spatial distribution of the damage area, and to assess the damage severity, a fast and accurate loss assessment method is of great importance for effective administration. The objectives of this study were to determine suitable spectral features for armyworm detection and to develop a mapping method at a regional scale on the basis of satellite remote sensing image data. RESULTS: Armyworm infestation can cause a significant change in the plant's leaf area index, which serves as a basis for infestation monitoring. Among the number of vegetation indices that were examined for their sensitivity to insect damage, the modified soil-adjusted vegetation index was identified as the optimal vegetation index for detecting armyworm. A univariate model relying on two-date satellite images significantly outperformed a multivariate model, with the overall accuracy increased from 0.50 to 0.79. CONCLUSION: A mapping method for monitoring armyworm infestation at a regional scale has been developed, based on a univariate model and two-date multispectral satellite images. The successful application of this method in a typical armyworm outbreak event in Tangshan, Hebei Province, China, demonstrated the feasibility of the method and its promising potential for implementation in practice.

The fumigant has high pesticidal activity, but does not disperse in soils as well as other fumigants. This study assessed the use of CO2 as a propellant to improve soil dispersion and diffusion by evaluating the partitioning and degradation of DMDS after carbonation in four vineyard soils collected in California. RESULTS: The soil with the highest organic carbon content (Clarksburg) had the highest soil-water partition coefficient (K-d) (P < 0.001), which increased after carbonation. However, DMDS sorption decreased in the Mecca and Fowler soils. Henry's law constant (K-h), which measures a compound's potential for partitioning between air and water, doubled from 0.04 to 0.10 with the addition of CO2, indicating less DMDS solubility. Carbonation did not negatively affect DMDS's half-lives in the different soils. CONCLUSION: While trials are needed for validation of field-scale impacts, carbonation had mixed effects on soil partitioning and no discernable impact on degradation, but greatly decreased DMDS water solubility. This indicates that carbonation could improve some facets of DMDS diffusion and dispersion, depending on soil properties (carbon content and moisture), without greatly affecting its other behaviors.

TI Bark water uptake promotes localized hydraulic recovery in coastal redwood crown SO PLANT CELL AND ENVIRONMENT LA English DT Article DE embolism; fog; foliar uptake; phellem; sequoia sempervirens ID FOLIAR ABSORPTION; XYLEM; EMBOLISM; TREES; FOG; PERMEABILITY; CAVITATION; DROUGHT; CONTEXT; FOREST AB Coastal redwood (Sequoia sempervirens), the world's tallest tree species, rehydrates leaves via foliar water uptake during fog/rain events. Here we examine if bark also permits water uptake in redwood branches, exploring potential flow mechanisms and biological significance. Using isotopic labelling and microCT imaging, we observed that water entered the xylem via bark and reduced tracheid embolization. Moreover, prolonged bark wetting (16 h) partially restored xylem hydraulic conductivity in isolated branch segments and whole branches. Partial hydraulic recovery coincided with an increase in branch water potential from about -5.5 +/- 0.4 to -4.2 +/- 0.3MPa, suggesting localized recovery and possibly hydraulic isolation. As bark water uptake rate correlated with xylem osmotic potential (R-2 = 0.88), we suspect a symplastic role in transferring water from bark to xylem. Using historical weather data from typical redwood habitat, we estimated that bark and leaves are wet more than 1000 h per year on average, with over 30 events being sufficiently long (>24 h) to allow for bark-assisted hydraulic recovery. The capacity to uptake biologically meaningful volumes of water via bark and leaves for localized hydraulic recovery throughout the crown during rain/fog events might be physiologically advantageous, allowing for relatively constant transpiration.

Here, we characterize an Arabidopsis Ca2+-regulated Na+/Ca2+ exchanger AtNCL that regulates Ca2+ and multiple physiological processes. AtNCL was localized to the tonoplast in yeast and plant cells. AtNCL appeared to mediate sodium (Na+) vacuolar sequestration and meanwhile Ca2+ release. The EF-hand domains within AtNCL regulated Ca2+ binding and transport of Ca2+ and Na+. Plants with diminished AtNCL expression were more tolerant to high CaCl2 but more sensitive to both NaCl and auxin; heightened expression of AtNCL rendered plants more sensitive to CaCl2 but tolerant to NaCl. AtNCL expression appeared to be regulated by the diurnal rhythm and suppressed by auxin. DR5::GUS expression and root responses to auxin were altered in AtNCL mutants. The auxin-induced suppression of AtNCL was attenuated in SLR/IAA14 and ARF6/8 mutants. The mutants with altered AtNCL expression also altered flowering time and FT and CO expression; FT may mediate AtNCL-regulated flowering time change. Therefore, AtNCL is a vacuolar Ca2+-regulated Na+/Ca2+ exchanger that regulates auxin responses and flowering time.

Mer.] is crucial to preserve the genus' genetic diversity, to secure material for genetic improvement and to support innovative and new research. Long-term conservation is accomplished through cryopreservation, that is done by storing cells or tissues at ultra-low temperature in liquid nitrogen (-196 degrees C). Droplet-vitrification, a combination of droplet freezing and solution-based vitrification, was used to establish a protocol for cryopreservation of pineapple genetic resources. This protocol was tested on cultivated and wild pineapple genotypes to establish a long-term germplasm security duplicate as well as to investigate cryo-injuries in the tissues by means of histological techniques. Excised shoot tips (0.5-1 mm with one primordial leaf) of different pineapple genotypes were precultured for 48 h on solid MS medium containing 0.3 M of sucrose. Three PVS2 exposure times (30, 45 and 60 min) were tested. The results showed high post cryopreservation survival for all genotypes evaluated. The best PVS2 exposure time varied according to genotype, although 45 min gave the best survival for the majority of genotypes. The technique was highly efficient in cryopreserving meristem shoot tips of different pineapple genotypes, and was also less laborious than techniques previously reported. This is a first report on application of the droplet-vitrification technique to diverse genotypes of cultivated and wild pineapples and the first report on histological changes occurring in cryopreserved Ananas tissue.

MOENCH; MAIZE AB The phenylpropanoid biosynthetic pathway that generates lignin subunits represents a significant target for altering the abundance and composition of lignin. The global regulators of phenylpropanoid metabolism may include MYB transcription factors, whose expression levels have been correlated with changes in secondary cell wall composition and the levels of several other aromatic compounds, including anthocyanins and flavonoids. While transcription factors correlated with downregulation of the phenylpropanoid biosynthesis pathway have been identified in several grass species, few transcription factors linked to activation of this pathway have been identified in C4 grasses, some of which are being developed as dedicated bioenergy feedstocks. In this study we investigated the role of SbMyb60 in lignin biosynthesis in sorghum (Sorghum bicolor), which is a drought-tolerant, high-yielding biomass crop. Ectopic expression of this transcription factor in sorghum was associated with higher expression levels of genes involved in monolignol biosynthesis, and led to higher abundances of syringyl lignin, significant compositional changes to the lignin polymer and increased lignin concentration in biomass. Moreover, transgenic plants constitutively overexpressing SbMyb60 also displayed ectopic lignification in leaf midribs and elevated concentrations of soluble phenolic compounds in biomass. Results indicate that overexpression of SbMyb60 is associated with activation of monolignol biosynthesis in sorghum. SbMyb60 represents a target for modification of plant cell wall composition, with the potential to improve biomass for renewable uses.

Initially, samples of Actaea racemosa from a single source were distinguished from other Actaea species based on principal component analysis and soft independent modeling of class analogies of flow injection mass spectrometry and proton nuclear magnetic resonance spectrometry metabolic fingerprints. The chemometric results for flow injection mass spectrometry and proton nuclear magnetic resonance spectrometry agreed well and showed similar agreement throughout the study. DNA sequencing using DNA sequence data from two independent gene regions confirmed the metabolic fingerprinting results. Differences were observed between A. racemosa samples from four different sources, although the variance within species was still significantly less than the variance between species. A model based on the combined A. racemosa samples from the four sources consistently permitted distinction between species. Additionally, the combined A. racemosa samples were distinguishable from commercial root samples and from commercial supplements in tablet, capsule, or liquid form. DNA sequencing verified the lack of authenticity of the commercial roots but was unsuccessful in characterizing many of the supplements due to the lack of available DNA.

The disease can reduce sugarcane yields significantly and causes severe stunting and mortality in highly susceptible cultivars. The causal agent of Ramu stunt has been investigated but its characterization has not been completed. Sugarcane cv. Ragnar from Papua New Guinea with symptoms of Ramu stunt was analyzed by next generation sequencing. Total RNA was extracted and whole transcriptome shotgun sequencing was performed using an Illumina platform. Over thirty-seven million reads with an average length of 100 nucleotides were obtained. More than eighteen thousand contigs were assembled and subjected to BLASTX analysis. Twenty-one contigs were virus related and six were associated with plant viruses. The BLAST algorithms revealed sequence similarity to Tenuivirus and Phlebovirus, genera of viruses whose members contain genomes consisting of multiple RNA segments. The six contigs derived from the RNA sequencing data correspond to six RNAs that compose the Ramu stunt virus genome. Primers were designed for each of the six RNAs and RT-PCR amplicons were obtained only from the symptomatic sugarcane. There was concordance between the sequence data of the contigs obtained from the NGS and that of the amplicons obtained by RT-PCR. The NGS approach allowed us to determine the complete genomic sequence of Ramu stunt virus. It is likely that this virus is the causal agent of Ramu stunt disease.

TI Projected irrigation requirements for upland crops using soil moisture model under climate change in South Korea SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE Climate change; Evapotranspiration; Irrigation requirement; Soil moisture model; South Korea; Upland crop ID WATER-BALANCE; REFERENCE EVAPOTRANSPIRATION; COEFFICIENT METHOD; CROPPING SYSTEMS; NEXT-GENERATION; CHANGE IMPACTS; NORTH CHINA; RIVER-BASIN; DROUGHT; REGION AB An increase in abnormal climate change patterns and unsustainable irrigation in uplands cause drought and affect agricultural water security, crop productivity, and price fluctuations. In this study, we developed a soil moisture model to project irrigation requirements (IR) for upland crops under climate change using estimated effective rainfall (ER), crop evapotranspiration (ETc) and the IR of 29 major upland crops in South Korea. The temperature and precipitation will increase, but the ER is projected to decrease under climate change. ETc and the net irrigation requirement (NIR) are expected to increase under climate change. Vegetable crops have less ER and more NIR than cereal crops with a similar amount of ETc, which means they are more sensitive to water scarcity and IR than cereal crops. In addition, we found that barley has the smallest daily ETc and IR but the highest increase rate in NIR under climate change, especially in the central part of South Korea. The NIR of Chinese cabbage-fall is the lowest in the northern region and increases moving southwards. The NIR of spinach is projected to increase gradually from the southern and eastern coastlines to the northern inland area. Onions have the largest ETc and NIR of the 29 upland crops, but they show small changes compared to other crops under climate change. Water scarcity is a major limiting factor for sustainable agricultural production. The variation of IR and ETc values for each crop under different climate change scenarios depends on the crop, soil, space, and meteorological characteristics. The results of this study can be used as a guideline for irrigation and soil water management for upland crops under climate change. (C) 2015 Elsevier B.V. All rights reserved.

TI Interaction of methylation-related genetic variants with circulating fatty acids on plasma lipids: a meta-analysis of 7 studies and methylation analysis of 3 studies in the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium SO AMERICAN JOURNAL OF CLINICAL NUTRITION LA English DT Article DE DNA methylation; epidemiology; fatty acids; genetic variants; plasma lipids ID CORONARY-ARTERY-DISEASE; DNA METHYLATION; WIDE ASSOCIATION; TANGIER-DISEASE; CARDIOVASCULAR-DISEASE; LOWERING DRUGS; DIET NETWORK; BLOOD-LIPIDS; SINGLE CPG; LOCI AB Background: DNA methylation is influenced by diet and single nucleotide polymorphisms (SNPs), and methylation modulates gene expression. Objective: We aimed to explore whether the gene-by-diet interactions on blood lipids act through DNA methylation. Design: We selected 7 SNPs on the basis of predicted relations in fatty acids, methylation, and lipids. We conducted a meta-analysis and a methylation and mediation analysis with the use of data from the CHARGE (Cohorts for Heart and Aging Research in Genomic Epidemiology) consortium and the ENCODE (Encyclopedia of DNA Elements) consortium. Results: On the basis of the meta-analysis of 7 cohorts in the CHARGE consortium, higher plasma HDL cholesterol was associated with fewer C alleles at ATP-binding cassette subfamily A member 1 (ABCA1) rs2246293 (beta =-0.6 mg/dL, P = 0.015) and higher circulating eicosapentaenoic acid (EPA) (beta = 3.87 mg/dL, P = 5.62 X 1021). The difference in HDL cholesterol associated with higher circulating EPA was dependent on genotypes at rs2246293, and it was greater for each additional C allele (beta = 1.69 mg/dL, P = 0.006). In the GOLDN (Genetics of Lipid Lowering Drugs and Diet Network) study, higher ABCA1 promoter cg14019050 methylation was associated with more C alleles at rs2246293 (beta = 8.84%, P = 3.51 x 10(18)) and lower circulating EPA (p =-1.46%, P = 0.009), and the mean difference in methylation of cg14019050 that was associated with higher EPA was smaller with each additional C allele of rs2246293 =-2.83%, P = 0.007). Higher ABCA1 cg14019050 methylation was correlated with lower ABCA1 expression (r =-0.61, P = 0.009) in the ENCODE consortium and lower plasma HDL cholesterol in the GOLDN study (r =-0.12, P = 0.0002). An additional mediation analysis was meta-analyzed across the GOLDN study, Cardiovascular Health Study, and the Multi-Ethnic Study of Atherosclerosis. Compared with the model without the adjustment of cg14019050 methylation, the model with such adjustment provided smaller estimates of the mean plasma HDL cholesterol concentration in association with both the rs2246293 C allele and EPA and a smaller difference by rs2246293 genotypes in the EPA-associated HDL cholesterol. However, the differences between 2 nested models were NS (P > 0.05). Conclusion: We obtained little evidence that the gene-by-fatty acid interactions on blood lipids act through DNA methylation.

Field studies of coyote (Canis latrans) reproductive performance suggest mean litter size changes in response to prey abundance. However, this relationship has been assessed primarily by using carcasses collected from trappers. The objective of this study was to assess whether nutritional manipulation prior to mating affected reproduction in adult female coyotes. We examined the effects of caloric restriction during the 7 months prior to estrus on the reproductive rates of 11 captive female coyotes and the subsequent initial survival of pups through two reproductive cycles. This was a 2-year study with a cross-over design so each female was monitored for reproductive performance on each of the two diet treatments. We assessed the number of implantation scars, number of pups born, sex ratios of pups, average pup weight at birth and 2- and 6-weeks of age, and the survival rates between implantation and 2-weeks of age for two diet treatments. We found the mean number of implantation sites and pups whelped during a reproductive cycle was influenced by food-intake prior to conception. Additionally, we found evidence suggesting the effects of nutritional stress may persist for additional breeding cycles. We also provided evidence suggesting well-fed females tended to have more male pups. Understanding how environmental factors influence reproductive output may improve model predictions of coyote population dynamics. Published by Elsevier B.V.

Four strains of Halobacteriovorax originally isolated in Vibrio parahaemolyticus O3:K6 host cells were separated from their prey by an enrichment-filtration-dilution technique for specificity testing in other bacteria. This technique was essential, since 0.45-mu m filtration alone was unable to remove infectious Vibrio minicells, as determined by scanning electron microscopy and cultural methods. Purified Halobacteriovorax strains were screened for predation against other V. parahaemolyticus strains and against Vibrio vulnificus, Vibrio alginolyticus, Escherichia coli O157:H7, and Salmonella enterica serovar Typhimurium DT104, all potential threats to seafood safety. They showed high host specificity and were predatory only against strains of V. parahaemolyticus. In addition, strains of Halobacteriovorax that were predatory for E. coli O157:H7 and S. Typhimurium DT104 were isolated from a tidal river at 5 ppt salinity. In a modified plaque assay agar, they killed their respective prey over a broad range of salinities (5 to 30 ppt). Plaques became smaller as the salinity levels rose, suggesting that the lower salinities were optimal for the predators' replication. These species also showed broader host specificity, infectious against each other's original hosts as well as against V. parahaemolyticus strains. In summary, this study characterized strains of Halobacteriovorax which may be considered for use in the development of broad-based biocontrol technologies to enhance the safety of commercially marketed shellfish and other foods.

TI Determination of Evolutionary Relationships of Outbreak-Associated Listeria monocytogenes Strains of Serotypes 1/2a and 1/2b by Whole-Genome Sequencing SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID SINGLE NUCLEOTIDE POLYMORPHISMS; MOBILE GENETIC ELEMENTS; MULTISTATE OUTBREAK; UNITED-STATES; INVASIVE LISTERIOSIS; MAXIMUM-LIKELIHOOD; PASTEURIZED MILK; EPIDEMIC CLONES; GASTROENTERITIS; SURVEILLANCE AB We used whole-genome sequencing to determine evolutionary relationships among 20 outbreak-associated clinical isolates of Listeria monocytogenes serotypes 1/2a and 1/2b. Isolates from 6 of 11 outbreaks fell outside the clonal groups or "epidemic clones" that have been previously associated with outbreaks, suggesting that epidemic potential may be widespread in L. monocytogenes and is not limited to the recognized epidemic clones. Pairwise comparisons between epidemiologically related isolates within clonal complexes showed that genome-level variation differed by 2 orders of magnitude between different comparisons, and the distribution of point mutations (core versus accessory genome) also varied. In addition, genetic divergence between one closely related pair of isolates from a single outbreak was driven primarily by changes in phage regions. The evolutionary analysis showed that the changes could be attributed to horizontal gene transfer; members of the diverse bacterial community found in the production facility could have served as the source of novel genetic material at some point in the production chain. The results raise the question of how to best utilize information contained within the accessory genome in outbreak investigations. The full magnitude and complexity of genetic changes revealed by genome sequencing could not be discerned from traditional subtyping methods, and the results demonstrate the challenges of interpreting genetic variation among isolates recovered from a single outbreak. Epidemiological information remains critical for proper interpretation of nucleotide and structural diversity among isolates recovered during outbreaks and will remain so until we understand more about how various population histories influence genetic variation.

TI An Environmental Shiga Toxin-Producing Escherichia coli O145 Clonal Population Exhibits High-Level Phenotypic Variation That Includes Virulence Traits SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID HEMOLYTIC-UREMIC-SYNDROME; SPINACH-ASSOCIATED OUTBREAK; UNITED-STATES; PATHOADAPTIVE MUTATIONS; 2 GENE; CONVERTING BACTERIOPHAGES; COMPARATIVE GENOMICS; BACTERIAL PATHOGENS; BACILLUS-SUBTILIS; CURLI VARIANTS AB Shiga toxin-producing Escherichia coli (STEC) serotype O145 is one of the major non-O157 serotypes associated with severe human disease. Here we examined the genetic diversity, population structure, virulence potential, and antimicrobial resistance profiles of environmental O145 strains recovered from a major produce production region in California. Multilocus sequence typing analyses revealed that sequence type 78 (ST-78), a common ST in clinical strains, was the predominant genotype among the environmental strains. Similarly, all California environmental strains belonged to H28, a common H serotype in clinical strains. Although most environmental strains carried an intact fliC gene, only one strain retained swimming motility. Diverse stx subtypes were identified, including stx(1a), stx(2a), stx(2c), and stx(2e). Although no correlation was detected between the stx genotype and Stx1 production, high Stx2 production was detected mainly in strains carrying stx(2a) only and was correlated positively with the cytotoxicity of Shiga toxin. All environmental strains were capable of producing enterohemolysin, whereas only 10 strains were positive for anaerobic hemolytic activity. Multidrug resistance appeared to be common, as nearly half of the tested O145 strains displayed resistance to at least two different classes of antibiotics. The core virulence determinants of enterohemorrhagic E. coli were conserved in the environmental STEC O145 strains; however, there was large variation in the expression of virulence traits among the strains that were highly related genotypically, implying a trend of clonal divergence. Several cattle isolates exhibited key virulence traits comparable to those of the STEC O145 outbreak strains, emphasizing the emergence of hypervirulent strains in agricultural environments.

TI Forest recovery in post-pasture Amazonia: Testing a conceptual model of space use by insectivorous understory birds SO BIOLOGICAL CONSERVATION LA English DT Article DE Antthrush; Fragmentation; Home range; Secondary forest; Telemetry; Woodcreeper ID ANIMAL MOVEMENT PATHS; RAIN-FOREST; BRAZILIAN AMAZONIA; FRACTAL DIMENSION; HOME-RANGE; GENE FLOW; FRAGMENTS; SECONDARY; DEFORESTATION; DISTRIBUTIONS AB Understanding how animals move in a complex habitat mosaic is critical to biodiversity conservation as deforested lands and secondary rainforests accumulate in landscapes previously dominated by primary forests. To visualize the spatiotemporal dynamics of secondary forest recovery after pasture abandonment, we formed a conceptual model predicting avian space use during a temporal sequence beginning with deforestation and continuing through regrowth of old secondary forest. We tested five predictions of the model at the Biological Dynamics of Forest Fragments Project near Manaus, Brazil, using 73 radio-tagged understory insectivores of three species: two woodcreepers (Glyphorynchus spirurus, Xiphorhynchus pardalotus) and a terrestrial antthrush (Formicarius colma). Both woodcreepers provided evidence to support all predictions except that of greater path tortuosity in primary forest. Woodcreepers using secondary forest had larger home ranges, larger core areas, and faster movement rates than in primary forest Further, the proportion of all species' core areas in primary forest exceeded the proportion of home ranges in primary forest. Formicarius colma showed a fundamentally different pattern than the woodcreepers: it essentially avoided secondary forest until 27-31 years after pasture abandonment, at which point movements were indistinguishable from those in primary forest. Formicarius colma and other terrestrial insectivores show implastic spatiotemporal responses to recovering secondary growth, which we suspect contributes to the sensitivity of this guild to forest disturbance. Quantifying the value of marginal (and economically inconsequential) habitats such as secondary forest will be essential as land managers strive to maintain species persistence and connectivity in increasingly heterogeneous tropical landscapes.

TI Understanding environmental DNA detection probabilities: A case study using a stream-dwelling char Salvelinus fontinalis SO BIOLOGICAL CONSERVATION LA English DT Article DE eDNA; Stream; Detection; Sampling; Genetics; Fish ID 2-SPECIES OCCUPANCY MODELS; ESTIMATING SITE OCCUPANCY; REAL-TIME PCR; WATER SAMPLES; BROOK TROUT; PARTICLE-TRANSPORT; MONITORING PROGRAM; EDNA; DEPOSITION; ABUNDANCE AB Environmental DNA sampling (eDNA) has emerged as a powerful tool for detecting aquatic animals. Previous research suggests that eDNA methods are substantially more sensitive than traditional sampling. However, the factors influencing eDNA detection and the resulting sampling costs are still not well understood. Here we use multiple experiments to derive independent estimates of eDNA production rates and downstream persistence from brook trout (Salvelinus fontinalis) in streams. We use these estimates to parameterize models comparing the false negative detection rates of eDNA sampling and traditional backpack electrofishing. We find that using the protocols in this study eDNA had reasonable detection probabilities at extremely low animal densities (e.g., probability of detection 0.18 at densities of one fish per stream kilometer) and very high detection probabilities at population-level densities (e.g., probability of detection >0.99 at densities of >= 3 fish per 100 m). This is substantially more sensitive than traditional electrofishing for determining the presence of brook trout and may translate into important cost savings when animals are rare. Our findings are consistent with a growing body of literature showing that eDNA sampling is a powerful tool for the detection of aquatic species, particularly those that are rare and difficult to sample using traditional methods.

We looked for population substructure among typical open-coastal and atypical estuarine habitats in seven asexual populations of P. umbilicalis from Maine to New Hampshire using eight expressed sequence tag-simple sequence repeats (EST-SSR) or microsatellite loci. Six genotypes were identified, four of which may represent recombinant genotypes from a recombination event that took place locally, or that took place prior to introduction to the Northwest Atlantic. Genotypic diversity was lowest in a population from Wiscasset, Maine, which inhabits an atypical habitat high in the intertidal zone of a bridge piling in an estuarine tidal rapid. Genotypic diversity was highest in the southernmost populations from New Hampshire; we identified two genotypes that were unique to the southernmost populations, and probably represent the most derived genotypes. We looked at genetic distances among populations in similar habitats, and found that populations were more closely related to their closest neighboring population than to a population in a similar habitat. We show that genotypic diversity within P. umbilicalis populations in the Gulf of Maine is relatively high and thus fits a model of high steady-state variation within asexual populations.

We hypothesized that SG with supplemental nitrogen (N) would deliver more positive effects on carbon (C) and N mineralization than USG. The objective of this study was to evaluate the effects of USG and SG, with or without supplemental inorganic N fertilizer on C and N mineralization in highly weathered Coastal Plain Ultisols. The application rate for SG and USG based on a corn yield goal of 112 kg ha(-1) was 40 Mg ha(-1). Inorganic N was added at the rate of 100 kg N ha(-1), also based on a corn yield of 7.03 tons ha(-1). Experimental treatments were: control (CONT) soil; control with N (CONT N); switchgrass residues (USG); USG with N (USG + N); switchgrass biochars at 250 degrees C (250SG); SG at 250 degrees C with N (250SG N); SG at 500 degrees C (500SG); and SG at 500 degrees C with N (500SG N). Cumulative and net CO2-C evolution was increased by the additions of SG and USG especially when supplemented with N. Soils treated with 250SG (8.6 mg kg(-1)) had the least concentration of total inorganic nitrogen (TIN) while the greatest amount of TIN was observed from the CONT N (19.0 mg kg(-1)). Our results suggest that application of SG in the short term may cause N immobilization resulting in the reduction of TIN. Published by Elsevier Ltd. C1 [Sigua, G. C.; Novak, J. M.; Watts, D.

TI Nitrogen uptake and N-use efficiency of Mediterranean cotton under varied deficit irrigation and N fertilization SO EUROPEAN JOURNAL OF AGRONOMY LA English DT Article DE Soil nitrates; N losses; Rainfall; Plant fractions; Seeds; Roots ID WATER-USE EFFICIENCY; COMPONENTS; YIELD; ACCUMULATION; PHOSPHORUS; CORN AB Efficient N management is essential to optimize yields and reduce degradation of the environment, but requires knowledge of deficit irrigation effects on crop yields and crop N outputs. This study assessed the N content and N-use efficiency of cotton over the 2008 and 2009 growing seasons in a single field site of the Thessaly Plain (central Greece). The experiment consisted of nine treatments with three fertilizer rates (60,110 and 160 kg N ha(-1)) split into three irrigation levels (approx. 1.0, 0.7 and 0.4 of the amount applied by the producer). Reduced water supply induced a shift in the distribution of N within the plant with seeds becoming an N sink under conditions of water stress. Total crop N increased linearly with irrigation level and reached a maximum average of 261 and 192 kg N ha(-1) in 2008 and 2009, respectively. Fertilizer application did not trigger a crop N or yield response and indicated that N inputs were in excess of crop needs. Variation in weather patterns appeared to explain annual differences of nitrate-N in the top soil and N uptake by the crop. The index of lint production efficiency (iNUE) detected crop responses caused by irrigation and annual effects, but failed to account for excessive N inputs due to mineral fertilizer applications. A maximum average iNUE of 9.6 was obtained under deficit irrigation, whereas an iNUE of 8.1 was obtained under 40 cm irrigation when crop N uptake was not excessive (192 kg ha(-1) in 2009). In contrast, NUE, as an estimator of N recovery efficiency, identified excessive fertilizer inputs as N losses to the environment and indicated that 60 kg N ha(-1) was a rate of high N removal efficiency and long-term N balance. However, NUE failed to account for crop N responses to irrigation and weather/management patterns. In this case study, neither index was able to detect all the factors influencing the N mass balance and both were required in order to provide a comprehensive evaluation of the environmental performance of our cropping system.

Little is known about effects of B12 supplementation on immune function. The present study aimed to evaluate effects of pre- and postnatal B12 supplementation on biomarkers of B12 status and vaccine-specific responses in mothers and infants. In a blinded, placebo-controlled trial, Bangladeshi women (n = 68, age 18-35 years, hemoglobin < 110 g/L, 11-14 weeks pregnant) were randomized to receive 250 mu g/day B12 or a placebo throughout pregnancy and 3-month postpartum along with 60 mg iron + 400 mu g folate. Women were immunized with pandemic influenza A (H1N1) vaccine at 26- to 28-week gestation. Blood from mothers (baseline, 72-h post-delivery, 3-month postpartum), newborns and infants (3-month) was analyzed for hemoglobin, B12, methylmalonic acid (MMA), total homocysteine (tHcy), ferritin and serum transferrin receptor, C-reactive protein (CRP) and alpha-1-acid glycoprotein (AGP). Vitamin B12 was also assessed in breast milk. H1N1-specific antibodies were determined in plasma and colostrum/breast milk. At baseline, 26 % women were B12 deficient (< 150 pmol/L), 40 % had marginal status (150-220 pmol/L), 43 % had elevated MMA (> 271 nmol/L), and 31 % had elevated tHcy (> 10 mu mol/L). Supplementation increased B12 in plasma, colostrums and breast milk (p < 0.05) and lowered MMA in neonates, mothers and infants at 3 months (p < 0.05). B12 supplementation significantly increased H1N1-specific IgA responses in plasma and colostrums in mothers and reduced proportion of infants with elevated AGP and CRP compared with placebo. Supplementation with 250 mu g/day B12 during pregnancy and lactation substantially improved maternal, infant and breast milk B12 status. Maternal supplementation improved H1N1 vaccine-specific responses in mothers only and may alleviate inflammatory responses in infants.

During tomato fruit ripening, associated with color changes from green to red involving the conversion of chloroplasts to chromoplasts are changes of aromatic volatile profiles. Although the biosynthetic pathways for some aromatic volatiles have been established in tomato fruit recently, our knowledge of regulatory mechanisms is still rudimentary. On the other hand, many internal and external factors modify volatile metabolism in tomato fruit. This review first summarizes the current knowledge of expression patterns and biosynthetic pathways of aromatic volatiles in tomato fruit along with the role of ethylene in their biosynthesis. The impact of internal and pre- and postharvest external factors on volatile composition is then discussed. This review will provide critical information for research on tomato aromatic volatiles and their manipulation.

It is particularly unclear how multiple extrinsic factors with contrasting effects among seasons are related to declines in population numbers and changes in mean body size and whether there is a strong role for density-dependence. The primary goal of this study was to identify the roles of seasonal variation in climate driven environmental direct effects (mean stream flow and temperature) vs. density-dependence on population size and mean body size in eastern brook trout (Salvelinus fontinalis). We use data from a 10-year capture-mark-recapture study of eastern brook trout in four streams in Western Massachusetts, USA to parameterize a discrete-time population projection model. The model integrates matrix modeling techniques used to characterize discrete population structures (age, habitat type, and season) with integral projection models (IPMs) that characterize demographic rates as continuous functions of organismal traits (in this case body size). Using both stochastic and deterministic analyses we show that decreases in population size are due to changes in stream flow and temperature and that these changes are larger than what can be compensated for through density-dependent responses. We also show that the declines are due mostly to increasing mean stream temperatures decreasing the survival of the youngest age class. In contrast, increases in mean body size over the same period are the result of indirect changes in density with a lesser direct role of climate-driven environmental change.

Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO2], c(i), a constant drawdown in CO2 (c(a)-c(i)), and a constant c(i)/c(a). These strategies can result in drastically different consequences for leaf gas-exchange. The accuracy of Earth systems models depends in part on assumptions about generalizable patterns in leaf gas-exchange responses to varying c(a). The concept of optimal stomatal behavior, exemplified by woody plants shifting along a continuum of these strategies, provides a unifying framework for understanding leaf gas-exchange responses to c(a). To assess leaf gas-exchange regulation strategies, we analyzed patterns in c(i) inferred from studies reporting C stable isotope ratios (C-13) or photosynthetic discrimination () in woody angiosperms and gymnosperms that grew across a range of c(a) spanning at least 100ppm. Our results suggest that much of the c(a)-induced changes in c(i)/c(a) occurred across c(a) spanning 200 to 400ppm. These patterns imply that c(a)-c(i) will eventually approach a constant level at high c(a) because assimilation rates will reach a maximum and stomatal conductance of each species should be constrained to some minimum level. These analyses are not consistent with canalization toward any single strategy, particularly maintaining a constant c(i). Rather, the results are consistent with the existence of a broadly conserved pattern of stomatal optimization in woody angiosperms and gymnosperms. This results in trees being profligate water users at low c(a), when additional water loss is small for each unit of C gain, and increasingly water-conservative at high c(a), when photosystems are saturated and water loss is large for each unit C gain.

The goal of this study was to examine natural resistance of plantation-grown African mahogany (Khaya spp.) to decay fungi and termite feeding, in order to better evaluate the potential use of this material as a suitable replacement for Brazilian mahogany wood. Heartwood and sapwood of two African mahogany species, Khaya ivorensis and Khaya senegalensis, were evaluated for resistance to decay by five wood-rot fungi as well as to feeding by subterranean termites in laboratory tests. In addition, density values were evaluated and examined for correlation to the observed natural durability properties. Overall, results showed heartwood of both species to be more resistant than sapwood to all fungi tested. K. senegalensis sapwood showed the lowest resistance to decay fungi, while K. senegalensis heartwood had the highest resistance to both brown-and white-rot fungi as well as to the dry-rot fungus tested. Both wood species showed some resistance to feeding by subterranean termites, with significantly higher resistance in heartwood compared to sapwood. In fungal and termite tests, durability was not found to be correlated to density values for either Khaya spp. tested. Results from this study suggest plantation-grown African mahogany exhibits similar natural durability properties as Brazilian mahogany, supporting the potential for its use as a suitable substitute to better meet the demands of the wood products industry.

Smith), is a highly mobile insect pest of a wide range of host crops. However, this pest of tropical origin cannot survive extended periods of freezing temperature but must migrate northward each spring if it is to re-infest cropping areas in temperate regions. The northward limit of the winter-breeding region for North America extends to southern regions of Texas and Florida, but infestations are regularly reported as far north as Qu,bec and Ontario provinces in Canada by the end of summer. Recent genetic analyses have characterized migratory pathways from these winter-breeding regions, but knowledge is lacking on the atmosphere's role in influencing the timing, distance, and direction of migratory flights. The Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used to simulate migratory flight of fall armyworm moths from distinct winter-breeding source areas. Model simulations identified regions of dominant immigration from the Florida and Texas source areas and overlapping immigrant populations in the Alabama-Georgia and Pennsylvania-Mid-Atlantic regions. This simulated migratory pattern corroborates a previous migratory map based on the distribution of fall armyworm haplotype profiles. We found a significant regression between the simulated first week of moth immigration and first week of moth capture (for locations which captured a parts per thousand yen10 moths), which on average indicated that the model simulated first immigration 2 weeks before first captures in pheromone traps. The results contribute to knowledge of fall armyworm population ecology on a continental scale and will aid in the prediction and interpretation of inter-annual variability of insect migration patterns including those in response to climatic change and adoption rates of transgenic cultivars.

Bendelac, Albert TI Intrinsic functional defects of type 2 innate lymphoid cells impair innate allergic inflammation in promyelocytic leukemia zinc finger (PLZF)-deficient mice SO JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY LA English DT Article DE Allergic mechanisms; innate lymphoid cells; mouse models ID NATURAL HELPER-CELLS; LUNG INFLAMMATION; T-CELLS; AIRWAY INFLAMMATION; IMMUNE-RESPONSE; NKT CELLS; ASTHMA; HOMEOSTASIS; LINEAGE; HYPERREACTIVITY AB Background: The transcription factor promyelocytic leukemia zinc finger (PLZF) is transiently expressed during development of type 2 innate lymphoid cells (ILC2s) but is not present at the mature stage. We hypothesized that PLZF-deficient ILC2s have functional defects in the innate allergic response and represent a tool for studying innate immunity in a mouse with a functional adaptive immune response. Objective: We determined the consequences of PLZF deficiency on ILC2 function in response to innate and adaptive immune stimuli by using PLZF(-/-) mice and mixed wild-type:PLZF(-/-) bone marrow chimeras. Methods: PLZF(-/-) mice, wild-type littermates, or mixed bone marrow chimeras were treated with the protease allergen papain or the cytokines IL-25 and IL-33 or infected with the helminth Nippostrongylus brasiliensis to induce innate type 2 allergic responses. Mice were sensitized with intraperitoneal ovalbumin-alum, followed by intranasal challenge with ovalbumin alone, to induce adaptive T(H)2 responses. Lungs were analyzed for immune cell subsets, and alveolar lavage fluid was analyzed for ILC2-derived cytokines. In addition, ILC2s were stimulated ex vivo for their capacity to release type 2 cytokines. Results: PLZF-deficient lung ILC2s exhibit a cell-intrinsic defect in the secretion of IL-5 and IL-13 in response to innate stimuli, resulting in defective recruitment of eosinophils and goblet cell hyperplasia. In contrast, the adaptive allergic inflammatory response to ovalbumin and alum was unimpaired. Conclusions: PLZF expression at the innate lymphoid cell precursor stage has a long-range effect on the functional properties of mature ILC2s and highlights the importance of these cells for innate allergic responses in otherwise immunocompetent mice.

TI Application of advection-diffusion routing model to flood wave propagation: A case study on Big Piney River, Missouri USA SO JOURNAL OF EARTH SCIENCE LA English DT Article DE advection-diffusion equation; hydrograph; flood wave propagation; recession limb ID HYDROGRAPH; TRANSPORT AB Flood wave propagation modeling is of critical importance to advancing water resources management and protecting human life and property. In this study, we investigated how the advection-diffusion routing model performed in flood wave propagation on a 16 km long downstream section of the Big Piney River, MO. Model performance was based on gaging station data at the upstream and downstream cross sections. We demonstrated with advection-diffusion theory that for small differences in watershed drainage area between the two river cross sections, inflow along the reach mainly contributes to the downstream hydrograph's rising limb and not to the falling limb. The downstream hydrograph's falling limb is primarily determined by the propagated flood wave originating at the upstream cross section. This research suggests the parameter for the advectiondiffusion routing model can be calibrated by fitting the hydrograph falling limb. Application of the advection diffusion model to the flood wave of January 29, 2013 supports our theoretical finding that the propagated flood wave determines the downstream cross section falling limb, and the model has good performance in our test examples.

TI Recovery of Campylobacter from External and Internal Spleen Samples from Baby Broiler Chicks Following Various Routes of Inoculation SO JOURNAL OF FOOD SAFETY LA English DT Article ID COMMERCIAL BROILERS; BREEDER HENS; SALMONELLA SEROVARS; JEJUNI AB Campylobacter have been found in lymphoid tissue of poultry, but the location in these tissues has not been determined. The objective of this study was to determine if Campylobacter are on the outside or on the inside of the spleen. For external (ES) spleen sampling 2 days post-inoculation, each spleen was rinsed with 3mL of Bolton's enrichment broth (BEB). For internal (IS) spleen sampling, each rinsed spleen was submerged into 70% ethanol for 10s, removed and submerged into 0.85% saline. The spleen was then placed into a sterile bag, macerated with 3mL of BEB and stomached for 30s before incubation. All samples and the correlating ceca were sampled for Campylobacter jejuni. Overall in four different experiments with baby chicks inoculated by oral, ocular or cloacal routes, Campylobacter was recovered from 75% (82/109) of the ES, 71% (77/109) of the IS and from 100% (109/109) of the ceca. Ethanol and saline samples were all negative for Campylobacter, suggesting that ethanol immersion is adequate to kill C.jejuni on the external surface. With Campylobacter in the internal tissue of the spleen, the organism appears to be systemic. Further research will determine the colonization mechanisms required for this bacterium in these different tissues. Practical ApplicationsIt is very difficult to sample the free flowing blood of a living chicken for bacteria without introducing contamination from the skin. This paper describes an effective method of sampling the internal portion of the spleen without introducing external contamination. By doing so, this indicates that the bacteria were systemic and will travel with the blood to all of the internal organs and tissues throughout the bird's body. Therefore when the bacteria are not isolated from certain tissues, it means that reservoirs were either not established or did not persist in that particular tissue even though the bacteria did flow through with the blood. Unless all of the potential reservoirs and sources of bacteria such as Campylobacter and Salmonella are identified and fully understood, successful intervention strategies may not be possible. It would be important to know if reservoirs of these bacteria present in internal organs and tissues can periodically seed the intestinal and/or reproductive tracts of adult breeder birds, thus providing a source of contamination to the offspring.

Thus, we examined the effect of a high Glu milieu on quercetin (Q) metabolism in HepG2 cells. HepG2 cells were grown for 3 days in Glu ranging from 5.5 to 50mmol/L and/or cyanidin-3-glucoside (C3G) ranging from 0 to 25mol/L. Subsequently, the capacity of HepG2 cells to metabolize Q was assessed for up to 16h. Q metabolites were analyzed by high-performance liquid chromatography. Four major Q metabolites were observed in the culture medium and inside the HepG2 cells. Three of these metabolites appear to be sulfated forms of Q or methylated Q, and one was a methylated Q. These metabolites and Q itself were reduced or tended to be reduced in cells grown in a high Glu compared to a normal Glu medium. Addition of C3G or superoxide dismutase plus catalase did not prevent or enhance reduction of Q metabolites. In vitro, a hyperglycemic milieu decreases the production of the principal Q metabolites in HepG2 cells, mediated through mechanisms independent of oxidative stress.

Furthermore, as pregnancy progresses, there is increased need to provide methyl groups for methylation reactions associated with the synthesis of new proteins and, unlike normal-BMI American women, low-BMI Indian women are unable to increase methionine transmethylation and remethylation rates as pregnancy progresses from trimester 1 to 3. This also negatively influences birth weight. Objective: The aim was to determine the effect of dietary supplementation with energy and protein from 12 +/- 1 wk of gestation to time of delivery compared with no supplement on pregnancy outcomes, protein kinetics, and the fluxes of the methyl group donors serene and glycine. Methods: Protein kinetics and serine and glycine fluxes were measured by using standard stable isotope tracer methods in the fasting and postprandial states in 24 pregnant women aged 22.9 +/- 0.7 y with low BMIs [BMI (in kg/m(2)) <= 18.51 at 12 +/- 1 wk (trimester 1) and 30 +/- 1 wk (trimester 3) of gestation. After the first measurement, subjects were randomly assigned to either receive the supplement (300 kcal/d, 15 g protein/d) or no supplement. Results: Supplementation had no significant effect on any variable of pregnancy outcome, and except for fasting state decreases in leucine flux (125 +/- 7.14 compared with 113 +/- 5.06 mu mol . kg(-1) . h(-1); P = 0.04) and nonoxidative disposal (110 +/- 6.97 compared with 101 +/- 3.69 mu mol . kg(-1) . h(-1); P=0.02) from trimesters 1 to 3, it had no effect on any other leucine kinetic variable or urea, glycine, and serine fluxes. Conclusion: We conclude that in Indian women with a low BMI, supplementation with energy and protein from week 12 of pregnancy to time of delivery does not improve pregnancy outcome, whole-body protein kinetics, or serine and glycine fluxes.

TI Absorption and Distribution Kinetics of the C-13-Labeled Tomato Carotenoid Phytoene in Healthy Adults SO JOURNAL OF NUTRITION LA English DT Article DE phytoene; tomato; compartmental modeling; kinetics; carotenoid ID PROSTATE-CANCER; BETA-CAROTENE; SERUM LYCOPENE; CELL-CULTURE; IN-VITRO; PHYTOFLUENE; RISK; METABOLISM; MICE; MEN AB Background: Phytoene is a tomato carotenoid that may contribute to the apparent health benefits of tomato consumption. Although phytoene is a less prominent tomato carotenoid than lycopene, it is a major carotenoid in various human tissues. Phytoene distribution to plasma lipoproteins and tissues differs from lycopene, suggesting the kinetics of phytoene and lycopene differ. Objective: The objective of this study was to characterize the kinetic parameters of phytoene absorption, distribution, and excretion in adults, to better understand why biodistribution of phytoene differs from lycopene. Methods: Four adults (2 males, 2 females) maintained a controlled phytoene diet (1-5 mg/d) for 42 d. On day 14, each consumed 3.2 mg C-13-phytoene, produced using tomato cell suspension culture technology. Blood samples were collected at 0, 1-15, 17, 21, and 24 h and 2, 3, 4, 7, 10, 14, 17, 21, and 28 d after 13C-phytoene consumption. Plasma unlabeled and plasma-labeled phytoene concentrations were determined using ultra-HPLC quadrupole time-of-flight mass spectrometry, and data were fit to a 7-compartment carotenoid kinetic model using WinSAAM 3.0.7 software. Results: Subjects were compliant with a controlled phytoene diet, consuming a mean SE of 2.5 +/- 0.6 mg/d, resulting in a plasma unlabeled phytoene concentration of 71 +/- 14 nmol/L. A maximal plasma C-13-phytoene concentration of 55.6 +/- 5.9 nM was achieved 19.8 +/- 9.2 h after consumption, and the plasma half-life was 2.3 +/- 0.2 d. Compared with previous results for lycopene, phytoene bioavailability was nearly double at 58% +/- 19%, the clearance rate from chylomicrons was slower, and the rates of deposition into and utilization by the slow turnover tissue compartment were nearly 3 times greater. Conclusions: Although only differing from lycopene by 4 double bonds, phytoene exhibits markedly different kinetic characteristics in human plasma, providing insight into metabolic processes contributing to phytoene enrichment in plasma and tissues compared with lycopene. This trial was registered at clinicaltrials.gov as NCT01692340.

TI Bioavailability of Alfrutamide and Caffedymine and Their P-Selectin Suppression and Platelet -Leukocyte Aggregation Mechanisms in Mice SO JOURNAL OF NUTRITION LA English DT Article DE CVD; alfrutamide; caffedymine; platelet activation; COX inhibition ID COA-TYRAMINE N-(HYDROXYCINNAMOYL)TRANSFERASE; ATHEROSCLEROSIS; EXPRESSION; THROMBOSIS; FLOW; INFLAMMATION; ACTIVATION; DISEASE; PROTEIN; CLONING AB Background: Alfrutamide and caffedymine are phenolic amides found in plants, including garlic and cocoa. However, the bioavailability of alfrutamide and caffedymine and their effects on cardiovascular diseases (CVDs), particularly via effects on P-selectin expression(PSE) and platelet -leukocyte aggregation (PLA), are unknown. Objective: The objective of this study was to investigate the bioavailability of alfrutamide and caffedymine and their effects on PSE and PLA, which are frequently involved in the progression of CVDs. Methods: Cyclooxygenase (COX) I and COX-II activities and cAMP were determined by using COX "and cAMP kits. Bioavailability was determined by HPLC analysis of plasma samples from Swiss Webster mice orally administered alfrutamide and caffedymine (10 mu g each). PSE and PLA were also measured by flow cytometry using blood samples from the same mice. Results: At 0.05 mu mol/L, alfrutamide and caffedymine inhibited COX-I and COX-II by 20-40% (P < 0.05) and 16-33% (P < 0.05), respectively, compared with the control. At 0.1 p.mol/L, the 2 compounds also inhibited platelet PSE by 28% (P < 0.05) and 35% (P < 0.05), respectively, compared with the control. The (32-adrenoceptor antagonists IC1118551 and butoxamine partially suppressed the inhibition of PSE by caffedymine, suggesting that)32 receptors are involved in inhibition by caffedymine but not by alfrutamide. At the same concentration (0.1 pi,mol/L), however, these 2 compounds inhibited PLA by 24-32% (P < 0.05) compared with the control. In addition, mice administered caffedymine and alfrutamide orally (10 mu g/35 g body weight) exhibited maximum concentrations >0.6 p,mol/L and significant inhibition of PSE by 23-34% (P < 0.05) and PLA by 20-27% (P < 0.05) compared with control mice. Conclusions: These data show the adequate bioavailability of alfrutamide and caffedymine and their different mechanisms of suppressing PSE and PLA: alfrutamide exerts its effects only via COX inhibition, whereas caffedymine works through both COX inhibition and cAMP amplification.

Most of this research has targeted the possible functions of garlic in maintaining cardiovascular health and in preventing and treating cancer. A wide range of outcome variables has been used to investigate the bioactivity of garlic, ranging from direct measures of health status such as cholesterol concentrations, blood pressure, and changes in tumor size and number, to molecular and biochemical measures such as mRNA gene expression, protein concentration, enzyme activity, and histone acetylation status. Determination of how garlic influences mRNA gene expression has proven to be a valuable approach to elucidating the mechanisms of garlic bioactivity. Preclinical studies investigating the health benefits of garlic far outnumber human studies and have made frequent use of mRNA gene expression measurement. There is an immediate need to understand mRNA gene expression in humans as well. Although safety and ethical constraints limit the types of available human tissue, peripheral whole blood is readily accessible, and measuring mRNA gene expression in whole blood may provide a unique window to understanding how garlic intake affects human health.

Epidemiologic (including monozygotic twin and migrant) studies highlight the substantial role of environment and nutrition in IBD etiology. Here we review the literature supporting the developmental and environmental origins hypothesis of IBD. We also provide a detailed exploration of how the human microbiome and epigenome (primarily through DNA methylation) may be important elements in the developmental origins of IBD in both children and adults.

Of particular interest is protein, which accounts for the majority of shrimp feed content and expense. The current study evaluated seven cottonseed meal and protein products. Most of the samples were derived from a glandless cotton variety that lacks significant levels of the antinutritive compound, gossypol. The various protein fractions were evaluated for apparent crude protein, crude lipid, and energy digestibility when fed to juvenile Pacific White Shrimp, Litopenaeus vannamei. Apparent energy digestibility for the protein fractions derived from the glandless seed ranged from 76.7% for ground kernels to 94.6% for protein isolate, and these values were greater than the value obtained for the commercial meal that contained gossypol (64%). Apparent protein digestibility for the six glandless-cotton-based samples varied from 72.3% for the ground full-fat kernels to 94.1% for the protein isolate, and these values were mostly higher than the value obtained for the commercial meal (82.3%). The high apparent digestibility values demonstrate that low-gossypol cottonseed protein products may be useful as a cost-effective replacement for more expensive protein sources in L. vannamei diets.

However, commercial products are often developed for use in livestock and are not optimized for wildlife. Consequently, it is incumbent upon researchers and managers to apply commercial products appropriately to optimize program outcomes. We tested more than 800 serum samples from mallards for antibodies to influenza A virus with the IDEXX AI MultiS-Screen Ab test to evaluate assay performance. Applying the test per manufacturer's recommendations resulted in good performance with 84% sensitivity and 100% specificity. However, performance was improved to 98% sensitivity and 98% specificity by increasing the recommended cut-off. Using this alternative threshold for identifying positive and negative samples would greatly improve sample classification, especially for field samples collected months after infection when antibody titers have waned from the initial primary immune response. Furthermore, a threshold that balances sensitivity and specificity reduces estimation bias in seroprevalence estimates. Published by Elsevier B.V. C1 [Shriner, Susan A.; VanDalen, Kaci K.; Root, J.

This study employed exploratory spatial data analysis of population growth, loss of natural land, and climate change data, all projected at county level for the conterminous United States as part of the USDA Forest Service's 2010 RPA Assessment. Location and geographical extent of projected significant "hotspots" of individual and multiple stressors were analyzed with respect to the location of at-risk natural ecosystems (protected lands, imperiled species) and the social and economic characteristics of human population within and outside the hotspots. While hotspots of projected climate change are broadly distributed across the Southwest, Northern Midwest, and Northeast, hotspots of projected natural land loss clustered in the Southeast and Pacific Northwest, and the primary area of overlap for multiple changes was the Southwest. Most counties in hotspots are currently home to higher numbers of at -risk or listed threatened and endangered (T&E) species than those outside. Also, up to three-quarters of the lands stringently managed to preserve their unique natural and scientific values are projected to be in hotspots of one or more stressors. Findings will be useful in identifying areas in which the greatest emerging land use management challenges will likely be concentrated due to change in one or more stressors. Findings will also inform land use planning decisions, and most importantly, provide information that will prioritize limited resources for mitigation, restoration, and management in areas of highest need. While our analysis shows notable differences in social and economic characteristics of counties projected to be in and outside hotspots, it also suggests the need for an in-depth study to compare sensitivity and adaptive capacity at community scale to compare the vulnerability of communities.

The defined construct is applied to atmospheric pressure chemical ionization mass spectrometry (MS) of triacylglycerols (TAG). A simulacrum has precisely defined components, specifically a simulacrum sum, four Possibilities to Observe, two Cases, and eight solutions. A simulacrum with no restrictions is the First General Form of a Simulacrum. When one value is specified to be 1 (as in MS), the construct is called a Unit Simulacrum, also called the First Specified Form of a Simulacrum. When one value is 1 and no value can be greater than 1 (the two specifications dictated by mass spectrometry), the construct is called the Second Specified Form of a Simulacrum, or the Mass Spectrometry Simulacrum. Simulacra are used with three Critical Ratios calculated from raw abundances in mass spectra of TAG to provide structural information about the degree of unsaturation in TAG, the identity and quantity of regioisomers, and other structural characteristics. Three-level-deep nested simulacrum solutions yield the recently reported Updated Bottom Up Solution, from which the protonated molecule, [MH](+), and all diacylglycerol-like fragments, [DAG](+), of TAG can be reproduced from the Critical Ratios. Thus, the simulacrum solutions constitute a reduced data set in which more information is provided in fewer values than raw abundances, such that the Critical Ratios constitute a compact library of mass spectra.

Members of Gossypium produce subepidermal pigment glands in their leaves that contain the dimeric sesquiterpenoid gossypol as well as other biosynthetically related terpenoids. In addition to gossypol, a previously unknown dimeric sesquiterpenoid, gossypolhemiquinone (GHQ), was identified in trace amounts in G. thurberi, a member of the D genome. Other members of the D genome of Gossypium were subsequently found to contain this compound, but GHQ was not detected in commercial cotton cultivars. When fed to Helicoverpa zea in an artificial diet, GHQ delayed days -to -pupation, reduced pupal weights, and survival to adulthood to a lesser or equal extent than gossypol in comparison to the control diet. However, GHQ had a synergistic effect on survival and days -to -pupation when combined with gossypol at the highest dosage tested (0.18%; 15.5:84.5 GHQ:gossypol). Because gossypol exhibits anticancer activity, GHQ was also evaluated for its anti -cancer activity against the National Cancer Institute's 60 -Human Tumor Cell Line Screen. Significant inhibitory activity against most of these cell lines was not observed, but the results may offer some promise against leukemia cancer cell lines. Published by Elsevier Ltd.

We conducted a time series experiment crossing sterilized and non-sterilized soil with four different residue treatments. We measured weed seed germination rates, radicle elongation, and disease incidence in seed germination bioassays. We also monitored cover crop-derived, isoflavone allelochemicals in these bioassays. We partitioned the total weed suppression into three sources: microbe-only inhibition, residue-only inhibition, and the microbe-residue interaction. Microbial activity suppressed weed germination and growth for 30 days, while cover crop-derived allelochemicals provided suppression for a limited time. There was an antagonistic interaction between microbes and allelochemicals. This interaction was strongest for water-soluble allelochemicals, while residue fractions containing intact plant tissues retained greater suppressiveness even in the presence of a live microbial community. Microbial activity can directly suppress weed germination and growth, but microorganisms also indirectly help weeds by degrading cover crop-derived allelochemicals. As a result of these interactions, cover crop-derived weed suppression in agricultural soils shifts from an early allelochemical-dominated phase to a later phase where microbial suppression is more important.

Dietary acrylamide is a suspected human carcinogen, and health concerns related to dietary acrylamide have been raised worldwide. French fries and potato chips contribute a significant proportion to the average daily intake of acrylamide, especially in developed countries. One way to mitigate health concerns related to acrylamide is to develop potato cultivars that have reduced contents of the acrylamide precursors asparagine, glucose and fructose in tubers. We generated a large number of silencing lines of potato cultivar Russet Burbank by targeting the vacuolar invertase gene VInv and the asparagine synthetase genes StAS1 and StAS2 with a single RNA interference construct. The transcription levels of these three genes were correlated with reducing sugar (glucose and fructose) and asparagine content in tubers. Fried potato products from the best VInv/StAS1/StAS2-triple silencing lines contained only one-fifteenth of the acrylamide content of the controls. Interestingly, the extent of acrylamide reduction of the best triple silencing lines was similar to that of the best VInv-single silencing lines developed previously from the same potato cultivar Russet Burbank. These results show that an acrylamide mitigation strategy focused on developing potato cultivars with low reducing sugars is likely to be an effective and sufficient approach for minimizing the acrylamide-forming potential of French fry processing potatoes.

Here, we address putative drivers underlying variable W-i responses in a wide range of grassland communities. W-i was estimated from carbon isotope discrimination in archived herbage samples from 16 contrasting fertilizer treatments in the Park Grass Experiment, Rothamsted, England, for the 1915 to 1929 and 1995 to 2009 periods. Changes in W-i were analyzed in relation to nitrogen input, soil pH, species richness, and functional group composition. Treatments included liming as well as phosphorus and potassium additions with or without ammonium or nitrate fertilizer applications at three levels. W-i increased between 11% and 25% (P < 0.001) in the different treatments between the two periods. None of the fertilizers had a direct effect on the change of W-i (Delta W-i). However, soil pH (P < 0.05), species richness (P < 0.01), and percentage grass content (P < 0.01) were significantly related to Delta W-i. Grass-dominated, species-poor plots on acidic soils showed the largest Delta W-i (+14.7 mu mol mol(-1)). The Delta W-i response of these acidic plots was probably related to drought effects resulting from aluminum toxicity on root growth. Our results from the Park Grass Experiment show that W-i in grassland communities consistently increased over a wide range of nutrient inputs, soil pH, and plant community compositions during the last century.

Although a potentially important factor in the worldwide obesity epidemic, the fundamental mechanisms underlying such developmental programming of energy balance are poorly understood, limiting our ability to intervene. Most studies of developmental programming of energy balance have focused on persistent alterations in the regulation of energy intake; energy expenditure has been relatively underemphasised. In particular, very few studies have evaluated developmental programming of physical activity. The aim of this review is to summarise recent evidence that early environment may have a profound impact on establishment of individual propensity for physical activity. Recently, we characterised two different mouse models of developmental programming of obesity; one models fetal growth restriction followed by catch-up growth, and the other models early postnatal overnutrition. In both studies, we observed alterations in body-weight regulation that persisted to adulthood, but no group differences in food intake. Rather, in both cases, programming of energy balance appeared to be due to persistent alterations in energy expenditure and spontaneous physical activity (SPA). These effects were stronger in female offspring. We are currently exploring the hypothesis that developmental programming of SPA occurs via induced sex-specific alterations in epigenetic regulation in the hypothalamus and other regions of the central nervous system. We will summarise the current progress towards testing this hypothesis. Early environmental influences on establishment of physical activity are likely an important factor in developmental programming of energy balance. Understanding the fundamental underlying mechanisms in appropriate animal models will help determine whether early life interventions may be a practical approach to promote physical activity in man.

The Photochemical Reflectance Index (PRI) has shown promise when measured at short timesteps to remotely estimate dynamics in xanthophyll pigment interconversion a plant photoprotective mechanism that results in lowered photosynthetic efficiency. To gain a better understanding of this dynamic spectral response to environmental conditions, we investigated PRI over two seasons (2013 and 2014) in rainfed soft white spring wheat (Triticum aestivum L.). Highly temporally resolved (measurement frequency = five minutes) in-situ radiometric measurements of PRI were collected at field plots of varying nitrogen (N) and soil water conditions (n = 16). To represent the diurnal magnitude of xanthophyll pigment inter conversion, we use a delta PRI (Delta PRI) derived from a midday PRI (xanthophyll de-epoxidation state) and an early morning PRI (xanthophyll epoxidation state). We hypothesize that Delta PRI can empirically deconvolve the diurnally changing (facultative) from the seasonally changing (constitutive) component of the PRI signal. In this study, Delta PRI demonstrated less sensitivity than an uncorrected PRI to leaf area index (LAI) and leaf chlorophyll content throughout the growing season. Delta PRI! was correlated with continuous, unattended crop responses associated with vapor pressure deficit (0.50 > R-2 > 0.48), stomatal conductance (R-2 = 0.47), and air temperature (0.42 > R-2 > 35). Further, the sensitivity with which Delta PRI responded to solar radiation under varying N treatments and periods of soil water availability (surplus, depletion, and deficit) suggests that crop growth may be inhibited by a xanthophyll cycle mediated stress response, detectable by Delta PRI A major implication of these findings is that highly temporally and spatially resolved Delta PRI data could be used to track plant status in response to changing environmental conditions.

In the past decade, airborne scanning LiDAR (Light Detection and Ranging) has emerged as a promising tool for sample surveys aimed at improving estimation of aboveground forest biomass. This technology is now employed routinely in forest management inventories of some Nordic countries, and there is eager anticipation for its application to assess changes in standing biomass in vast tropical regions of the globe in concert with the UN REDD program to limit C emissions. In the rapidly expanding literature on LiDAR-assisted biomass estimation the assessment of the uncertainty of estimation varies widely, ranging from statistically rigorous to ad hoc. In many instances, too, there appears to be no recognition of different bases of statistical inference which bear importantly on uncertainty estimation. Statistically rigorous assessment of uncertainty for four large LiDAR-assisted surveys is expounded. (C) 2015 Elsevier Inc. All rights reserved.

Examples are forest management inventories, where a linking model is used in combination with airborne laser scanning data to estimate stand-level forest parameters where no or too few observations are collected within the stand. This paper focuses on different approaches to estimating the variances of those estimates. We compared a variance estimator which is based on the estimation of superpopulation parameters with variance estimators which are based on predictions of finite population values. One of the latter variance estimators considered the spatial autocorrelation of the residuals whereas the other one did not. The estimators were applied using timber volume on stand level as the variable of interest and photogrammetric image matching data as auxiliary information. Norwegian National Forest Inventory (NFI) data were used for model calibration and independent data clustered within stands were used for validation. The empirical coverage proportion (ECP) of confidence intervals (CIs) of the variance estimators which are based on predictions of finite population values was considerably higher than the ECP of the CI of the variance estimator which is based on the estimation of superpopulation parameters. The ECP further increased when considering the spatial autocorrelation of the residuals. The study also explores the link between confidence intervals that are based on variance estimates as well as the well-known confidence and prediction intervals of regression models. 2015 The Authors.

Tools that can characterize their distributions along with other features important as wildlife habitat, such as woody shrub cover, would be useful for research and management purposes. Three dimensional lidar data and Landsat time series disturbance products have both shown varying promise in their ability to characterize aspects of dead biomass and understory cover, but studies exploring the combination of the remote sensing datasets calibrated with field data to model difficult to map habitat components are limited. The purpose of this study was to 1) relate lidar and Landsat time series products to field collected calibration data to produce maps of important post-fire wildlife habitat components including snags of varying sizes and the availability of a woody shrub layer; and 2) compare the individual performance of the Landsat and lidar datasets for predicting the distributions of these difficult to map forest habitat features Using 164 field calibration plots and remote sensing predictors, we modeled and mapped the distributions of our response variables including snag classes (dbh >= 40 cm; >= 50 cm, and >= 75 cm) and woody shrub cover thresholds (>= 30 and >= 50% cover) at 10 m resolutions. Remote sensing predictors included various lidar structure and topography variables and Landsat time series products representing the pre-fire forest, disturbance magnitude, and current forest condition. A model was chosen for mapping purposes using AIC model selection and then by comparing leave-one-out-cross-validation error matrices to choose among competing models. We were able to predict and map all response variables with moderate accuracies and variable sensitivity (true positive) and specificity (true negative) rates. All snag and shrub models were considered to have "good" predictive performance as indicated by area under the curve values (0.74-0.91), with percent correctly classified values ranging from 69-85% when a probability threshold is chosen that balances false positive and false negative errors. Landsat models performed marginally better than lidar structure models according to classification statistics. Landsat-only models had slightly less accuracy than models that included lidar and Landsat data, but often with greater errors than the combined model. The ability to map the response variables with moderate errors and acceptable accuracies for many applications was through the fusion of these remote sensing datasets. (C) 2015 Elsevier Inc.

The climatic changes expected during the next decades - large increases in mean temperature, increased heat waves, and significant long-term regional drying in the western USA - will likely increase chronic forest stress and mortality. The aim of this research is to develop and apply a new forest vulnerability index (FVI) associated with drought and high temperatures across the Pacific Northwest region (PNW; Oregon and Washington) of the USA during the MODIS Aqua era (since 2003). Our technique incorporates the alterations to canopy water and energy exchange processes caused by drought and high temperatures with spatially continuous MODIS land surface temperature (LST) and evapotranspiration (ET), and with Parameter-elevation Relationships on Independent Slopes Model (PRISM) precipitation (P) data. With P and ET, we calculate a monthly water balance variable for each individual pixel normalized by forest type group (FTG), and then difference the water balance with the corresponding normalized monthly meanLST to calculate a monthly forest stress index (FSI). We then extract the pixel-specific (800-m resolution) statistically significant temporal trends of the FSI from 2003 to 2012 by month (April to October). The FVI is the slope of the monthly FSI across years, such that there is a FVI for each month. Statistically significant positive slopes indicate interannual increases in stress leading to expected forest vulnerability (positive FVI) for a given month. Positive FVI values were concentrated in the months of August and September, with peak vulnerability occurring at different times for different FTGs. Overall, increased vulnerability rates were the highest in drier FTGs such as Ponderosa Pine, Juniper, and Lodgepole Pine. Western Larch and Fir/Spruce/Mountain Hemlock groups occupy moister sites but also had relatively high proportion of positive FVI values. The Douglas-fir group had the second largest total area of increased vulnerability due to its large areal extent in the study area. Based on an analysis using imagery viewed in Google Earth, we confirm that areas with increased vulnerability are associated with greater amounts of stress and mortality. The FVI is a new way to conceptualize and monitor forest vulnerability based on first-order principles and has the potential to be generalized to other geographical areas. (C) 2015 Elsevier Inc.

Gabon has recently launched a National Climate Action Plan with the intent of establishing a National Forest Monitoring System that meets the Intergovernmental Panel on Climate Change (IPCC) 2006 guidelines for the Agriculture, Forestry and Other Land Use (AFOLU) sector. The assessment of areas of forest cover and forest cover change is essential to estimate activity data, defined as areas of various categories of land use change by the IPCC guidelines. An appropriately designed probability sample can be used to estimate forest cover and net change and their associated uncertainties and express them in the form of confidence intervals at selected probability thresholds as required in the IPCC 2006 guidelines and for reporting to the United Nations Framework Convention on Climate Change (UNFCCC). However, wall-to-wall mapping is often required to provide a comprehensive assessment of forest resources and as input to land use plans for management purposes, but wall-to-wall approaches are more expensive than a sample based approach based on visual interpretation and require specialized equipment and staff. The recent release of the University of Maryland (UMD) Global Forest Change (GFC) map products could be an alternative for tropical countries wishing to develop their own wall-to-wall forest map products but without the resources to do so. Therefore, the aim of this study is to assess the feasibility of replacing national wall-to-wall forest maps with forest maps obtained from the UMD GFC initiative. A model assisted regression (MAR) estimator was applied using the combination of reference data obtained from a probability sample and forest cover and forest cover change maps either (i) produced nationally or (ii) obtained from the UMD GFC data. The resulting activity data are potentially more accurate than the SRS estimate and provide an assessment of the precision of the estimate which is not available from map accuracy indices alone. Results obtained for 2000 and 2010 for both the national and UMD GFC datasets confirm the high level of forest cover in Gabon, more than 235 million ha representing approximately 88.5% of the country. Although the UMD GFC dataset provides a reliable means of producing area statistics at national level combined with appropriate sample reference data, thus offering an alternative to nationally produced datasets (i) the classification errors associated with the Global dataset have non-negligible effects on both the estimate and the precision which supports the more general statement that map data should not be used alone to produce area estimates, and (ii) the maps obtained from the UMD GFC dataset require specific calibration of the tree cover percentage representing a non -negligible effort requiring specialized staff and equipment. Guidelines on how to use and further improve UMD GFC maps for national reporting are suggested. However, this additional effort would still most likely be less than the production of national based maps. (C) 2015 Elsevier Inc All rights reserved.

TI Transabdominal and transrectal ultrasonography of fetuses in Wurttemberg ewes: Correlation with gestational age SO ANIMAL SCIENCE JOURNAL LA English DT Article DE ewe; fetus; gestation age; ultrasound ID FETAL; SHEEP; PREGNANCY AB It is useful to determine the gestational age in sheep to provide essential information for effective flock management practices. The aims of this study were to evaluate the efficacy and practical aspects for using two ultrasound techniques, transabdominal and transrectal, in determining the gestational age in Wurttemberg ewes. Monitoring of embryo and fetus developmental stages during the ewes' gestation was carried out with real time ultrasound using a transabdominal convex probe, frequency 3.5 MHz, and a transrectal linear probe, frequency 7.5 MHz. The size of the embryonic vesicle during the period from the 23rd to the 38th day of gestation can be used as a confirmational indicator of gestational age when the transrectal probe is used. The occipital nasal diameter correlated with the gestational age with both transabdominal (P < 0.05) and transrectal probes (P < 0.01) from the 46th to the 63rd day of gestation. The biparietal diameter of the fetal head measured by transabdominal probe during the period from the 46th to the 63rd day of gestation correlates with gestation age (P < 0.05). The diameter of the fetal eye orbit monitored by transrectal probe from the 46th to the 63rd day of gestation also correlated well with gestational age (P < 0.05).

TI Numerical simulation of a dust event in northeastern Germany with a new dust emission scheme in COSMO-ART SO ATMOSPHERIC ENVIRONMENT LA English DT Article DE Mineral dust; Dust model; Regional atmospheric model; COSMO-ART; PM10 ID EROSION THRESHOLD; MINERAL DUST; TRANSPORT; MODEL; IMPACTS; AEROSOL; AREAS AB The dust emission scheme of Shao (2004) has been implemented into the regional atmospheric model COSMO-ART and has been applied to a severe dust event in northeastern Germany on 8th April 2011. The model sensitivity to soil moisture and vegetation cover has been studied. Soil moisture has been found to be relatively high in the model during the investigation period and has been reduced by different degree to investigate the resulting changes in dust emissions. Two different vegetation datasets have been tested as model input: the climatological vegetation cover data of COSMO-ART (ECOCLIMAP) and the SPOT5 remote sensing vegetation cover data for the time of the event. By varying soil moisture, vegetation cover and by restricting the potential emission area, a set of eleven simulations was generated. Vegetation cover during the event was about 24% lower on average compared to the climatological mean. Thus, dust emissions modeled with SPOTS vegetation exceeded that modeled with climatological data by a factor of about 5. The modeled dust concentrations were compared with in-situ measurements of aerosol concentration. The temporal evolutions of simulations and observations have significant correlations (0.42-0.85) especially in rural backgrounds. The lower correlations at urban sites are attributed to anthropogenic PM10 sources, which are not included in the model. However, a verification of the magnitude of modeled dust concentrations is not possible due to the uncertainty in soil moisture and emission area. (C) 2015 The Authors. Published by Elsevier Ltd.

Fiber strength is usually measured from bundles of fibers due to the difficulty of reliably measuring strength from individual cotton fibers. However, bundle fiber strength (BFS) is not always correlated with yarn strength since it is affected by multiple fiber properties involved in fiber-to-fiber interactions within a bundle in addition to the individual fiber strength. Molecular mechanisms responsible for regulating individual fiber strength remain unknown. Gossypium hirsutum near isogenic lines (NILs), MD52ne and MD90ne showing variations in BFS provide an opportunity for dissecting the regulatory mechanisms involved in individual fiber strength. Results: Comprehensive fiber property analyses of the NILs revealed that the superior bundle strength of MD52ne fibers resulted from high individual fiber strength with minor contributions from greater fiber length. Comparative transcriptome analyses of the NILs showed that the superior bundle strength of MD52ne fibers was potentially related to two signaling pathways: one is ethylene and the interconnected phytohormonal pathways that are involved in cotton fiber elongation, and the other is receptor-like kinases (RLKs) signaling pathways that are involved in maintaining cell wall integrity. Multiple RLKs were differentially expressed in MD52ne fibers and localized in genomic regions encompassing the strength quantitative trait loci (QTLs). Several candidate genes involved in crystalline cellulose assembly were also up-regulated in MD52ne fibers while the secondary cell wall was produced. Conclusion: Comparative phenotypic and transcriptomic analyses revealed differential expressions of the genes involved in crystalline cellulose assembly, ethylene and RLKs signaling pathways between the MD52ne and MD90ne developing fibers. Ethylene and its phytohormonal network might promote the elongation of MD52ne fibers and indirectly contribute to the bundle strength by potentially improving fiber-to-fiber interactions. RLKs that were suggested to mediate a coordination of cell elongation and SCW biosynthesis in other plants might be candidate genes for regulating cotton fiber cell wall assembly and strength.

It is generally believed that cellulose in cell wall microfibrils has both crystalline and amorphous regions. However, there is evidence that appears to be contrary to this assumption. Here we show, using 1064-nm FT-Raman spectroscopy, that (1) compared to the crystalline state, cellulose in the never-dried native state is laterally aggregated but in a less-than crystalline state wherein internal chains are water-accessible, (2) hydroxymethyl groups (CH2OH) in cellulose exist not only in the tg conformation but also in the gt rotamer form, and (3) in native-state fibrils, low-frequency Raman bands due to cellulose crystal domains are absent, indicating the lack of crystallinity. Further evidence of the absence of crystallinity of the fibrils was the failure of the normal 64 % H2SO4 hydrolysis procedure to produce nanocellulose crystals from untreated wood. X-ray diffraction data obtained on wood, treated-wood, and wood-cellulose samples were consistent with the new finding and indicated that full-width-at-half-height of the X-ray diffractograms and lateral disorder in samples as measured by Raman were correlated (R-2 = 0.95).

Cellulose was extracted from Cladophora glomerata and subjected to microfluidization with or without enzymatic hydrolysis pretreatment to produce CNFs. Increasing microfluidization passes produced smaller algal CNFs with more uniform sizes and lower crystallinity. Combining microfluidization with an enzymatic hydrolysis pretreatment, the algal CNFs' crystallinity decreased further, but the diameter distribution showed little change. The algal CNFs were compared to CNFs produced from bleached eucalyptus pulp (BEP), with the algal CNFs having significantly higher crystallinity, smaller diameter and better thermal stability. The XRD spectra of algal and BEP CNFs were simulated by Mercury 3.0 software. The results indicated that BEP CNFs are mainly cellulose I beta with a random orientation, while algal CNFs are likely a hybrid of cellulose I alpha with preferred orientations along the [100] and [010] axes with a March-Dollase factor of 0.65.

TI A typology of time-scale mismatches and behavioral interventions to diagnose and solve conservation problems SO CONSERVATION BIOLOGY LA English DT Article DE decision theory; economics; psychology; socioecological systems; temporal lags ID CLIMATE-CHANGE; SCIENCE; SYSTEMS; CHOICE; RISK AB Ecological systems often operate on time scales significantly longer or shorter than the time scales typical of human decision making, which causes substantial difficulty for conservation and management in socioecological systems. For example, invasive species may move faster than humans can diagnose problems and initiate solutions, and climate systems may exhibit long-term inertia and short-term fluctuations that obscure learning about the efficacy of management efforts in many ecological systems. We adopted a management-decision framework that distinguishes decision makers within public institutions from individual actors within the social system, calls attention to the ways socioecological systems respond to decision makers' actions, and notes institutional learning that accrues from observing these responses. We used this framework, along with insights from bedeviling conservation problems, to create a typology that identifies problematic time-scale mismatches occurring between individual decision makers in public institutions and between individual actors in the social or ecological system. We also considered solutions that involve modifying human perception and behavior at the individual level as a means of resolving these problematic mismatches. The potential solutions are derived from the behavioral economics and psychology literature on temporal challenges in decision making, such as the human tendency to discount future outcomes at irrationally high rates. These solutions range from framing environmental decisions to enhance the salience of long-term consequences, to using structured decision processes that make time scales of actions and consequences more explicit, to structural solutions aimed at altering the consequences of short-sighted behavior to make it less appealing. Additional application of these tools and long-term evaluation measures that assess not just behavioral changes but also associated changes in ecological systems are needed.

TI Carbon pools in stream-riparian corridors: legacy of disturbance along mountain streams of south-eastern Wyoming SO EARTH SURFACE PROCESSES AND LANDFORMS LA English DT Article DE carbon budget; in-stream carbon; riparian carbon; disturbance; bark beetle ID LARGE WOODY DEBRIS; ORGANIC-MATTER; UNITED-STATES; OLD-GROWTH; TERRESTRIAL ECOSYSTEMS; HEADWATER STREAMS; PINE-BEETLE; FORESTS; DYNAMICS; BIOMASS AB Streams and their accompanying riparian environments are intrinsic components of terrestrial carbon cycling. However, they have been understudied in terms of the magnitude of their storage components and the role of disturbance in determining carbon storage capacity. This study presents partial carbon budgets for stream-riparian corridors along six study reaches in mountain headwater streams of southeast Wyoming to evaluate the impact of tie-driving, a historic disturbance legacy, on contemporary carbon storage. Detailed measurements of biomass were collected for in-stream components of carbon including fine and coarse particulate organic matter and in-stream large wood. Biomass was also estimated for riparian components including standing trees (live and dead), regenerating conifers, shrubs and herbaceous vegetation, downed wood, litter, and duff (partially decayed litter). Biomass was converted to carbon for all components and differences in storage were compared between tie-driven and non-driven reaches. Carbon content in riparian soils (to approximately 20 cm) was also measured. Twice the amount of carbon was stored in the riparian areas relative to the streams; most carbon was stored in standing trees (live and dead). While overall carbon storage within the riparian areas and streams were similar between disturbance conditions, the amount of carbon stored in large in-stream wood and downed wood on the floodplain was significantly higher in systems that were not tie-driven. The results of this study indicate that legacies of tie-driving influence carbon storage within the region, while also capturing baseline estimates of carbon storage in the wake of recent bark beetle infestations.

Properly functioning riparian systems slow runoff and store water, thus regulating extreme flows; however, riparian areas across the west are in a degraded condition with a majority of riparian systems not in proper functioning condition, and with widespread catastrophic erosion of water-storing peat and organic soils. Headcuts are the leading edge of catastrophic channel erosion. We used aerial imagery (1.4-3.3-cm pixel) to locate 163 headcuts in riparian areas in the Sweetwater subbasin of central Wyoming. We found 1-m-the generally available standard resolution for land management-and 30-cm pixel imagery to be inadequate for headcut identification. We also used Structure-from-Motion models built from ground-acquired imagery to model 18 headcuts from which we measured soil loss of 425-720 m(3). Normalized by channel length, this represents a loss of 1.1-1.8 m(3) m(-1) channel. Monitoring headcuts, either from ground or aerial imagery, provides an objective indicator of sustainable riparian land management and identifies priority disturbance-mitigation areas. Image-based headcut monitoring must use data on the order of 3.3 cm ground sample distance, or greater resolution, to effectively capture the information needed for accurate assessments of riparian conditions.

Boundary functions identify the upper limits of yield per unit of crop water use, and are useful for identifying constraints on WUE. The objectives of this research were to (1) develop a boundary function for maize using data (n=260) from research projects conducted at Bushland, TX, and (2) compare the yields of two recently developed, drought tolerant maize (Zea mays L) hybrids with the,boundary function and examine possible abiotic and biotic constraints on maximizing water use efficiency. A commercially available hybrid and an experimental hybrid were grown in 2012 (high environmental stress environment) and 2013 (moderate stress environment) in 48 weighing lysimeters containing soil monoliths of either clay loam, silt loam, sandy loam, or fine sand in a rain shelter facility. Plant density was 8 plants m(-2); irrigation treatments were 50% and 80% replacement of predicted crop evapotranspiration. The high stress environment of large vapor deficits and high temperatures during early reproductive growth stages in 2012 compared with 2013 significantly constrained the yield potential of both hybrids. It also showed the difference in stress tolerance of the hybrids with significant differences in WUE, yield and yield components between hybrids. Soil textural class was a significant constraint on WUE and harvest index (HI), with larger WUE and HI from crops in the fine sand and sandy loam compared with those of the crops in the clay loam and silt loam. Continued increases in the tolerance of maize to abiotic and biotic stresses will be necessary to maintain maize production in the southern High Plains region as irrigation water resources decline.

Despite debate about the merits of free-air CO2 enrichment (FACE) and open top chamber (OTC) systems, there have been no reports comparing crop yield responses to elevated CO2 in FACE and OTC systems using the same cultivar and location. In this study soybeans and winter wheat were grown for two years in FACE and OTC systems at the same time and location. An elevated CO2 treatment of ambient plus similar to 200 mu mol mol(-1) was applied 24 h per day for one cultivar of each species in the first year, and two cultivars of each species in the second year. Leaf area index, and midday leaf gas exchange rates were measured periodically, and total above ground biomass and seed yield were determined at maturity. In soybean, seed yield was increased by elevated CO2 in both FACE and OTC in both cultivars and years. However, the ratio of seed yield at elevated CO2 to that at ambient CO2 averaged significantly higher in OTC (1.49) than in FACE (1.27). In wheat, grain yield was increased by 15-30% by elevated CO2 for both cultivars and years in the OTC, but was not increased in either cultivar or year in the FACE system. No differences in midday photosynthetic rates occurred between OTC and FACE in either species for either CO2 treatment, except one season in wheat, but stomatal conductance was more reduced by elevated CO2 in OTC than in FACE. Short-term temporal variation in CO2 concentration was larger in FACE than in OTC. It is not clear from these results which method produces plant responses equivalent to those which may occur with increased atmospheric CO2. Published by Elsevier B.V.

Although differences between harvest treatments were not statistically significant (P < 0.05), average diameter, height, basal area and biomass were 8-18% lower in the WTH than in the SOH treatment 33 years after harvest whereas they differed by 2% 15 years after harvest. In contrast to results 15 years post-harvest, total forest floor mass and nutrient contents were twofold greater in the WTH than in the SOH treatment at 33 years post-harvest, due largely to differences in Oa horizon mass. Soil total C concentrations increased significantly (P < 0.05) over the first 15 years post-harvest in both harvest treatments. Decreases in soil C between 15 and 33 years post-harvest were not statistically significant. Soil total N increased significantly in both harvest treatments over the first 15 years post-harvest. Consistent decreases in soil total N occurred in the WTH treatment between years 15 and 33 post-harvest that bordered on statistical significance whereas total N was stable over that time period in the SOH treatment. The increases and decreases in soil N content cannot be explained by any known processes of N inputs or outputs. Harvest treatment effects on both Ca2+ and me observed at 15 years post-harvest are still observable and significant at 33 years post-harvest, although decreases between 15 and 33 years were found. Treatment effects and changes in soil exchangeable Ca2+ and Mg2+ are consistent with known inputs from decomposing logging residues, inputs from atmospheric deposition, and increments in forest floor and vegetation. No treatment effects were found for soil extractable P, but steady decreases over time were found. No treatment or time effects were found for soil exchangeable K. (C) 2015 Elsevier B.V.

Pinon-juniper (Pinus-Juniperus) woodlands in the western United States have expanded in area 2-10-fold since the late 1800s. Woodland control measures using chainsaws, heavy equipment and prescribed fire are used to restore big sagebrush (Artemisia tridentate Nutt.) steppe plant communities and reduce woody fuel loading. Immediate objectives in the initial control of Pinon-juniper are; (1) recovery of perennial herbaceous species to restore site composition, structure and processes (resilience) and resist invasion and dominance by invasive annual grasses (resistance) and (2) reducing woody fuel accumulations. Spanning a 7 year period (2006-2012), we compared herbaceous recovery following cutting and prescribed fire on three sites in mid and late succession western juniper (Juniperus occidentalis spp. occidentalis Hook.) woodlands in southeast Oregon. Treatments were untreated controls, partial cutting followed by fall broadcast burning (SEP), clear-cut and leave (CUT), and clear-cut and burn in winter (JAN), and spring (APR). Cover of herbaceous species was measured in three zones; interspace, litter mats around tree stumps (stump), and beneath felled trees. In interspace zones of all treatments, comprising between 51% and 63% of site areas, perennial bunchgrasses dominated two sites and co-dominated with invasive annual grasses at one site after treatment. Burning in the JAN treatments, when fuel moisture and relative humidity were high and temperatures cooler, reduced disturbance severity in stump and felled tree zones, which maintained perennial herbaceous understories and prevented or limited the presence of invasive annuals. Burning felled juniper in SEP and APR treatments resulted in moderate to high fire severity in stump and felled tree zones. At two sites, these fires consumed all fuel up to the 1000-h fuel class, largely eliminated herbaceous perennials, and created islands within treatments that enhanced annual grass invasion and dominance. To maintain or boost site resilience and resistance following control of late successional woodlands, reducing Pinon-juniper fuels by burning in winter provides managers with a low-impact option for conserving sagebrush steppe.

Strategically placed landscape treatments (SPLATS) are being used to reduce density of trees, shrubs, and surface fuels to limit wildfire intensity and spread, but may negatively impact fishers (Pekania pennanti). We used camera traps to survey for fishers among 1-km(2) grid cells of forest habitat in the Sierra National Forest, California. We used single-season (n = 894 cells) and multi-season (n = 361 cells) occupancy modeling to evaluate responses of fishers to fuel reduction in the 5 years prior to camera surveys. We also assessed occupancy in relation to burn history, elevation, and an index of canopy cover. Camera traps detected fishers most often between 1380 m and 1970 m elevation, and fisher occupancy was maximized at 0.80 at 1640 m elevation. Probability of detection was higher after initial fisher detection, in habitats with high canopy cover, and when surveys were done in fall to spring. Fisher occupancy was positively linked to canopy cover, and trended lower among cells with higher levels of managed burning or forest fires within 25 years of surveys, and in cells where 5 years of cumulative disturbance from restorative fuel reduction was higher. Local persistence declined 24% in areas with more restorative fuel reduction (0-100% of a cell), but was not diminished by prior burning, or disturbance from extractive activities (tree removals for commerce or hazard mitigation). Reduced local persistence by fishers in areas with extensive restorative fuel reduction was likely temporary; evidence from other sources intimated that they would resume higher use within a few years of ecological recovery. The trend for lower occupancy in extensively burned forest cells suggested that forest fires reduced but did not eliminate foraging opportunities for fishers. We also found that wildfires increased in frequency in our study area after the 1980s, and recent fires may increasingly impinge on higher elevation forests with higher fisher occupancy. Forest fuel reduction likely imposes a more limited short term cost to fisher habitat use than previously believed, but less is known about the responses of resting or denning fishers to management disturbance. Fuel reduction treatments could be intensified below 1450 m elevation, which may reduce spread of fires into higher elevation forests where fishers are more common, and where denning is focused.

We surveyed the literature, and identified 96 publications that reported data on dependent variables of seedling emergence and/or establishment and one or more independent variables of air temperature, soil temperature, precipitation and moisture availability. Our review suggests that seedling emergence and establishment for both species is highest at intermediate temperatures (20 to 25 degrees C), and higher precipitation and higher moisture availability support a higher percentage of seedling emergence and establishment at daily, monthly and annual timescales. We found that ponderosa pine seedlings may be more sensitive to temperature fluctuations whereas lodge pole pine seedlings may be more sensitive to moisture fluctuations. In a changing climate, increasing temperatures and declining moisture availability may hinder forest persistence by limiting seedling processes. Yet, only 23 studies in our review investigated the effects of driving climate and environmental variables directly. Furthermore, 74 studies occurred in a laboratory or greenhouse, which do not often replicate the conditions experienced by tree seedlings in a field setting. It is therefore difficult to provide strong conclusions on how sensitive emergence and establishment in ponderosa and lodgepole pine are to these specific driving variables, or to investigate their potential aggregate effects. Thus, the effects of many driving variables on seedling processes remain largely inconclusive. Our review stresses the need for additional field and laboratory studies to better elucidate the effects of driving climate and environmental variables on seedling emergence and establishment for ponderosa and lodgepole pine.

Significant losses to sugar yield and quality result if these wild plants are not removed. In cases of extreme infestation, fields are abandoned without harvest. No selective chemicals are available to differentiate conventional sugar beet from wild relatives and hand removal is labor intensive and expensive. Planting sugar beet varieties with tolerance to glyphosate is a potential solution for infested fields, but risk of gene flow to adjacent wild relatives must be determined. Previous research identified these populations as either Beta vulgaris L. subspecies maritima (L.) Arcang. or Beta macrocarpa Guss. This distinction is critical because B. v. subsp. maritima will readily cross hybridize with cultivated sugar beet while B. macrocarpa rarely will. In April 2011, we collected herbarium samples, mature seed, and leaf tissue from wild Beta populations in 25 infested sugar beet fields throughout the Imperial Valley. Bolting cultivated beets were identified at two locations. Taxonomy of whole plant herbarium samples was unclear due to wild beet stem elongation when under competition with sugar beet plants for canopy light. Morphology of plants from collected seed grown in non-competitive conditions assigned taxonomy of these populations to B. macrocarpa. We used molecular tools to determine the genetic structure of wild Beta populations throughout the Imperial Valley. Extracted DNA was genotyped with 22 simple sequence repeat molecular markers and evaluated for population structure. The bolting beet samples were clearly separated from the majority of B. macrocarpa samples, except for two. The remaining wild populations were further divided into two subgroups suggesting exchange of genetic information or a common ancestor.

In this study, a process-based model, the Soil-Plant-Atmosphere Continuum System (SPACSYS), was used to simulate the effects of different fertilisation regimes on crop yields, the dynamics of soil organic carbon (SOC) and total nitrogen (SN) stocks from 1990 to 2010, and soil CO2 (2007-2010) and N2O (2007-2008) emissions based on a long-term fertilisation experiment with a winter-wheat (Triticum Aestivum L.) and summer-maize (Zea mays L.) intercropping system in Eutric Cambisol (FAO) soil in southern China. Three fertilisation treatments were 1) unfertilised (Control), 2) chemical nitrogen, phosphorus and potassium (NPK), and 3) NPK plus pig manure (NPKM). Statistical analyses indicated that the SPACSYS model can reasonably simulate the yields of wheat and maize, the evolution of SOC and SN stocks and soil CO2 and N2O emissions. The simulations showed that the NPKM treatment had the highest values of crop yields, SOC and SN stocks, and soil CO2 and N2O emissions were the lowest from the Control treatment. Furthermore, the simulated results showed that manure amendment along with chemical fertiliser applications led to both C (1017 +/- 470 kg C ha(-1) yr(-1)) and N gains (91.7 +/- 15.1 kg N ha(-1) yr(-1)) in the plant-soil system, while the Control treatment caused a slight loss in C and N. In conclusion, the SPACSYS model can accurately simulate the processes of C and N as affected by various fertilisation treatments in the red soil. Furthermore, application of chemical fertilisers plus manure could be a suitable management for ensuring crop yield and sustaining soil fertility in the red soil region, but the ratio of chemical fertilisers to manure should be optimized to reduce C and N losses to the environment.

As a feasible option to control emissions from the terrestrial ecosystems, the scientific community has explored the possibility of enhancing soil carbon (C) storage capacity. Thus, restoration of damaged lands through conservation tillage, crop rotation, cover cropping, reforestation, sub-soiling of compacted lands, sustainable water management practices, and organic manuring are the major antidotes against attenuation of soil organic C (SOC) stocks. In this research, we focused on the effect of various man-made activities on soil biotic organics (e.g., green-, farm-yard manure, and composts) to understand how C fluxes from various sources contribute to the establishment of a new equilibrium in the terrestrial ecosystems. Although such inputs substitute a portion of chemical fertilizers, they all undergo activities that augment the rate and extent of decay to deplete the SOC bank. Here, we provide perspectives on the balancing factors that control the mineralization rate of organic matter. Our arguments are placed in the background of different land use types and their impacts on forests, agriculture, urbanization, soil erosion, and wetland destruction. (C) 2015 Elsevier Ltd.

TI Erosion of Sand from a Gravel Bed SO JOURNAL OF HYDRAULIC ENGINEERING LA English DT Article ID SEDIMENT TRANSPORT; MODEL DEVELOPMENT; ENTRAINMENT; SIMULATION; FRAMEWORK; RIVERS; CREEK; FLOW AB Cleaning of fine sediment out of gravel streambeds has become an important method to restore affected stream habitats. Introducing the increased flows needed to entrain fine sediments without eroding the coarser fractions of the bed and potentially destroying its usefulness as a habitat requires careful selection of flow strength. Toward this end, a series of flume experiments was conducted on the entrainment of sand from immobile gravel beds to determine the depth to which the sand could be eroded without the gravel being mobilized. A series of steady flows was imposed on three gravel beds filled with sand with median sizes of 0.2, 0.3, and 0.9 mm. The shear stress of the series of flows ranged from just above the critical shear stress for initiation of motion of the sand up to 0.9 times the critical stress of the 36.1-mm gravel. The experiments continued until the rate of fine sediment exiting the channel was very small. It was found that the cleanout depth of the sand was reasonably predicted by estimating the shear stress in the gravel as the product of bed shear stress and the value of the cumulative probability distribution function of the elevations of the gravel surface evaluated at the surface of the sand layer. The appropriate initiation of sediment motion criterion was found to be a function of the shear velocity of the flow and the fall velocity of the fine grains.

TI Hydrological Modeling Using a Multisite Stochastic Weather Generator SO JOURNAL OF HYDROLOGIC ENGINEERING LA English DT Article DE Multisite weather generator (MulGETS); Hydrological modeling; Interstation correlation; Single-site weather generator (WeaGETS) ID CLIMATE-CHANGE IMPACT; DAILY PRECIPITATION; DAILY RAINFALL; SOIL-EROSION; LOESS PLATEAU; RIVER-BASIN; TEMPERATURE; SCENARIOS; VARIABILITY; SIMULATION AB Weather data are usually required at several locations over a large watershed, especially when using distributed models for hydrological simulations. In many applications, spatially correlated weather data can be provided by a multisite stochastic weather generator, which considers the spatial correlation of weather variables. Prior to using a multisite weather generator for hydrological modeling, its ability to adequately represent the proper hydrological response needs to be assessed. This study assesses the effectiveness of a new multisite weather generator (MulGETS) for hydrological modeling over a Canadian watershed in the Province of Quebec. Prior to hydrological modeling, MulGETS is first evaluated with respect to reproducing the spatial correlation and statistical characteristics of precipitation and temperature for the studied watershed. Hydrological simulations obtained from MulGETS-generated precipitation and temperature are then compared with those obtained from a single-site weather generator (WeaGETS) and a WeaGETS-based lumped approach (WeaGETS-lumped) that averages the climate series over all stations in a watershed before running the single-site weather generator. The hydrology is simulated using two hydrological models: the conceptually lumped model HSAMI and the physically based distributed model CEQUEAU. When using the conceptually lumped model, the weather time series is first averaged over all stations in the watershed. The results show that the monthly mean discharge is accurately represented by both MulGETS-generated and WeaGETS-lumped-generated precipitation and temperature, whereas it is considerably underestimated by WeaGETS data for the snowmelt period. The MulGETS and WeaGETS-lumped data also show significant advantages in representing the monthly streamflow variability, which is underestimated by the WeaGETS outputs. Additionally, MulGETS and WeaGETS-lumped consistently perform better than WeaGETS for simulating extreme flows (snowmelt high flows and summer-autumn high and low flows). However, no obvious difference in performance was found between MulGETS and WeaGETS-lumped data for hydrological modeling. Moreover, the use of a physically based distributed model with MulGETS did not result in any significant performance gain compared with the much simpler combination of WeaGETS-lumped with a lumped hydrological model for the studied watershed. Overall, this study indicates that a single-site weather generator combined with a lumped hydrological model is sufficient for accurate hydrological simulations, even in the case of a large watershed.

This region is extremely fragile with endemic species like those that compose the upper mountain cloud forest (UMCF), and the dominant soils are typical Inceptisols. These forest environments are rapidly disappearing in Brazil. The changing land use combined with shallow Inceptisols lead to important effects on hydrology. Therefore, studies addressing streamflow behavior in these landscapes are urgently needed for understanding the groundwater recharge process. The objectives of this study were to investigate the role of shallow Inceptisols linked to the land use changes in the streamflow behavior of the Mantiqueira Range region and to understand the mechanisms of water flow into the saturated zone. To validate the study, a comparative analysis was developed for a representative watershed of Mantiqueira Range, whose land use is divided into pasture and Atlantic Forest, known as Lavrinha Creek Watershed (LCW) and a typical UMCF located inside of LCW. The results showed that in general, UMCF has greater potential for water percolation beginning from the surface layer towards the saturated zone. Micromorphological soil images provided useful information about the soil pore system associated with the physical properties of Inceptisols, and this background helped to understand the water recharge process and streamflow behavior. In addition, the water balance for two years (2009-2011) in the UMCF showed that the flow stored in the saturated zone occurs rapidly, increasing its potential for storage, characterized by the process of refilling water in the Inceptisols soil profile under forests in this region.

MOENCH; BROWN-MIDRIB MUTANTS; ACID O-METHYLTRANSFERASE; LACTATING DAIRY-COWS; BIOETHANOL PRODUCTION; BIOFUEL FEEDSTOCKS; FORAGE SORGHUM; GENE ENCODES; MAIZE AB The presence of lignin reduces the quality of lignocellulosic biomass for forage materials and feedstock for biofuels. In C4 grasses, the brown midrib phenotype has been linked to mutations to genes in the monolignol biosynthesis pathway. For example, the Bmr6 gene in sorghum (Sorghum bicolor) has been previously shown to encode cinnamyl alcohol dehydrogenase (CAD), which catalyzes the final step of the monolignol biosynthesis pathway. Mutations in this gene have been shown to reduce the abundance of lignin, enhance digestibility, and improve saccharification efficiencies and ethanol yields. Nine sorghum lines harboring five different bmr6 alleles were identified in an EMS-mutagenized TILLING population. DNA sequencing of Bmr6 revealed that the majority of the mutations impacted evolutionarily conserved amino acids while three-dimensional structural modeling predicted that all of these alleles interfered with the enzyme's ability to bind with its NADPH cofactor. All of the new alleles reduced in vitro CAD activity levels and enhanced glucose yields following saccharification. Further, many of these lines were associated with higher reductions in acid detergent lignin compared to lines harboring the previously characterized bmr6-ref allele. These bmr6 lines represent new breeding tools for manipulating biomass composition to enhance forage and feedstock quality.

We have applied a similar technology to deoptimize the capsid-coding region (P1) of foot-and-mouth disease virus (FMDV). Despite the introduction of 489 nucleotide changes (19%), synonymous deoptimization of the P1 region rendered a viable FMDV progeny. The resulting strain was stable and reached cell culture titers similar to those obtained for wild-type (WT) virus, but at reduced specific infectivity. Studies in mice showed that 100% of animals inoculated with the FMDV A12 P1 deoptimized mutant (A12-P1 deopt) survived, even when the animals were infected at doses 100 times higher than the dose required to cause death by WT virus. All mice inoculated with the A12-P1 deopt mutant developed a strong antibody response and were protected against subsequent lethal challenge with WT virus at 21 days postinoculation. Remarkably, the vaccine safety margin was at least 1,000-fold higher for A12-P1 deopt than for WT virus. Similar patterns of attenuation were observed in swine, in which animals inoculated with A12-P1 deopt virus did not develop clinical disease until doses reached 1,000 to 10,000 times the dose required to cause severe disease in 2 days with WT A12. Consistently, high levels of antibody titers were induced, even at the lowest dose tested. These results highlight the potential use of synonymous codon pair deoptimization as a strategy to safely attenuate FMDV and further develop live attenuated vaccine candidates to control such a feared livestock disease.

Most protein interactions are not binary or easily amenable to structural determination. Using infectious preparations of a polerovirus (Potato leafroll virus [PLRV]) and protein interaction reporter (PIR), a revolutionary technology that couples a mass spectrometric-cleavable chemical cross-linker with high-resolution mass spectrometry, we provide the first report of a host-pathogen protein interaction network that includes data-derived, topological features for every cross-linked site that was identified. We show that PLRV virions have hot spots of protein interaction and multifunctional surface topologies, revealing how these plant viruses maximize their use of binding interfaces. Modeling data, guided by cross-linking constraints, suggest asymmetric packing of the major capsid protein in the virion, which supports previous epitope mapping studies. Protein interaction topologies are conserved with other species in the Luteoviridae and with unrelated viruses in the Herpesviridae and Adenoviridae. Functional analysis of three PLRV-interacting host proteins in planta using a reverse-genetics approach revealed a complex, molecular tug-of-war between host and virus. Structural mimicry and diversifying selection-hallmarks of host-pathogen interactions-were identified within host and viral binding interfaces predicted by our models. These results illuminate the functional diversity of the PLRV-host protein interaction network and demonstrate the usefulness of PIR technology for precision mapping of functional host-pathogen protein interaction topologies.

Pathogen-produced necrotrophic effectors (NEs) are the major determinants for SNB on leaves. One such NE is SnTox3, which evokes programmed cell death and leads to disease when recognized by the wheat Snn3-B1 gene. Here, we developed saturated genetic linkage maps of the Snn3-B1 region using two F-2 populations derived from the SnTox3-sensitive line Sumai 3 crossed with different SnTox3-insensitive lines. Markers were identified and/or developed from various resources including previously mapped simple sequence repeats, bin-mapped expressed sequence tags, single nucleotide polymorphisms, and whole genome survey sequences. Subsequent high-resolution mapping of the Snn3-B1 locus in 5600 gametes delineated the gene to a 1.5 cM interval. Analysis of micro-colinearity of the Snn3-B1 region indicated that it was highly disrupted compared to rice and Brachypodium distachyon. The screening of a collection of durum and common wheat cultivars with tightly linked markers indicated they are not diagnostic for the presence of Snn3-B1, but can be useful for marker-assisted selection if the SnTox3 reactions of lines are first determined. Finally, we developed an ethyl methanesulfonate-induced mutant population of Sumai 3 where the screening of 408 M-2 families led to the identification of 17 SnTox3-insensitive mutants. These mutants along with the markers and high-resolution map developed in this research provide a strong foundation for the map-based cloning of Snn3-B1, which will broaden our understanding of the wheat-P. nodorum system and plant-necrotrophic pathogen interactions in general.

Host resistance is the most effective way to control this virus. To date, Wsm2 is the only wheat resistance gene that is genetically mapped. The objective of this study was to identify germplasm lines that might carry resistance genes different from Wsm2. Eight newly reported resistant germplasm lines were examined by allelic tests. To validate the allelic test results, five of them were further analysed for the inheritance of WSMV resistance. A Wsm2-linked marker was also genotyped on populations developed for the inheritance study. Our results suggested that the WSMV resistance in lines CItr9358, PI225288, PI243652, PI245439, PI245526 and PI478095 was controlled by either Wsm2 or a gene very closely linked to Wsm2. The resistance in PI243753 and PI321730, however, is likely controlled by a gene different from, but linked to Wsm2. The resistance in PI321730 might also involve some minor genes. This study provided useful information for breeders to select appropriate resistant lines to improve WSMV resistance in wheat.

We studied vernalization response among hybrid progeny derived from two domesticatedxwild crosses. The wild parents are vernalization-sensitive, late-flowering genotypes while both domesticated parents are vernalization insensitive. Parental lines and hybrid progeny were tested with (28days at 4 degrees C) and without vernalization (control). The difference in mean days to flower (DTF) between control and vernalization treatments was used to assess the flowering vernalization response. A wide range of DTF values was observed among the hybrid progeny. Strong genotype by environment interaction effect on DTF was observed for the parental accessions and hybrid progeny. We used the DTF values to select vernalization responsive and non-responsive progeny lines. However, the genotypexenvironment interaction strongly interfered with our selection. Chickpea breeders interested in using the wild progenitor as a donor of exotic traits should be aware of the possibility of introducing vernalization response alleles that may alter the phenology of their breeding materials in an unpredictable manner.

Radiotracer measurements in the LATS range indicate that the linear rise in influx continues well beyond nutritionally relevant concentrations (>10 mM), suggesting K+ transport may be pushed to extraordinary, and seemingly limitless, capacity. Here, we assess this rise, asking whether LATS measurements faithfully report transmembrane fluxes. Using K-42(+)-isotope and electrophysiological methods in barley, we show that this flux is part of a K+-transport cycle through the apoplast, and masks a genuine plasma-membrane influx that displays Michaelis-Menten kinetics. Rapid apoplastic cycling of K+ is corroborated by an absence of transmembrane K-42(+) efflux above 1 mM, and by the efflux kinetics of PTS, an apoplastic tracer. A linear apoplastic influx, masking a saturating transmembrane influx, was also found in Arabidopsis mutants lacking the K+ transporters AtHAK5 and AtAKT1. Our work significantly revises the model of K+ transport by demonstrating a surprisingly modest upper limit for plasma-membrane influx, and offers insight into sodium transport under salt stress.

Proximity to these destinations can affect the economic viability and marketing decisions of small-scale operations and may represent significant barriers to sustainability. Data were collected using a cross-sectional survey conducted by the US Department of Agriculture's (USDA) National Animal Health Monitoring System in 2011 using a stratified systematic sample of 16,000 small-scale (gross annual farm sales between US$10,000 and 499,999) operations from all 50 states. A total of 7925 food-animal operations were asked about the farthest one-way distance (in miles) to slaughter facilities, destinations where they sold animals or products, and feed sources. Across all small-scale operations, 95% of operations reported the farthest distance animals or products were transported for sale was 241 km (150 miles) or less. For distance to slaughter facilities, 95% of operations reported the farthest distance was 145 km (90 miles) or less. For feed shipped by a supplier, 95% of operations reported the farthest distance was 322 km (200 miles) or less. The 95th percentile for distance increased as farm sales increased, indicating larger operations were more likely to travel long distances. The results of this study are an important benchmark for understanding the economic and animal health implications of long transportation distances for operations that are small and/or focused on direct marketing.

A quantitative trait locus QYr.osu-5A on the long arm of chromosome 5A in bread wheat (Triticum aestivum L., 2n = 6x = 42; AABBDD) was previously reported to confer consistent resistance in adult plants to predominant stripe rust races, but the gene causing the quantitative trait locus (QTL) is not known. Single-nucleotide polymorphism (SNP) markers were used to saturate the QTL region. Comparative and syntenic regions between wheat and rice (Oryza sativa) were applied to identify candidate genes for QYr.osu-5A. TaXA21-A1, which is referred to as a wheat ortholog of OsXA21-like gene on chromosome 9 in rice, was mapped under the peak of the QYr.osu-5A. TaXA21-A1 not only explained the phenotypic variation in reaction to different stripe rust races but also showed significant effects on resistance to powdery mildew and Hessian fly biotype BP. The natural allelic variation resulted in the alternations of four amino acids in deduced TaXA21-A1 proteins. The interacting proteins of TaXA21-A1 were different from those identified by OsXA21 on rice chromosome 11 against bacterial leaf blight. TaXA21-A1 confers unique resistance against multiple pests in wheat but might not have common protein interactors or thus overlapping functions with OsXA21 in rice. XA21 function has diverged during evolution of cereal crops. The molecular marker developed for TaXA21-A1 would accelerate its application of the candidate gene at the QYr.osu-5A locus in wheat breeding programs.

TI Identification of markers linked to genes for sprouting tolerance (independent of grain color) in hard white winter wheat (HWWW) SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID QUANTITATIVE TRAIT LOCI; BREAD-WHEAT; SEED DORMANCY; PREHARVEST; RESISTANCE; MICROSATELLITE; CROSS; REGISTRATION; RICE; CHROMOSOMES AB Key message Hard red wheats can donate genes to hard white wheats for tolerance to preharvest sprouting, the effects are quantitative in nature, and may be tracked with previously described DNA markers. Pre-harvest sprouting (PHS) of wheat (Triticum aestivum L.) can negatively impact end-use quality and seed viability at planting. Due to preferences for white over red wheat in international markets, white wheat with PHS tolerance has become increasingly desired for worldwide wheat production. In general, however, red wheat is more tolerant of sprouting than white wheat. The main objective of this study was the identification of PHS tolerance conditioned by genes donated from hard red winter wheat, using markers applicable to the Great Plains hard white wheat gene pool. Three red wheat by white wheat populations, Niobrara/NW99L7068, NE98466/NW99L7068 and Jagalene/NW99L7068 were developed, and white-seeded progenies were analyzed for PHS tolerance and used to identify markers for the trait. In the three populations, marker loci with significant allelic effects were most commonly located on chromosomes of group 2, 3, 4 and 5, though additional markers were detected across the wheat genome. Chromosome 3A was the only chromosome with significant markers in all three populations. Markers were inconsistent across the three populations, and markers linked to tolerance-inducing loci were identified in both tolerant and susceptible parents. Additive effects of marker loci were common. In the present investigation, a wide range of PHS tolerance was observed, even though all lines were fixed for the recently reported positive TaPHS1 allele. PHS tolerance is controlled by additive major gene effects with minor gene effects where variations of minor gene effects were still unclear. C1 [Fakthongphan, Juthamas; Graybosch, R.

Here we examine pest-parasitoid interactions and dynamics in Arizona cotton from 1996 to 2010, during which a classical biological control program was implemented. Two native species, Eretmocerus eremicus Rose and Zolnerowich and Encarsia meritoria (Gahan) were either largely or completely displaced by exotic Eretmocerus sp. (Ethiopia) and Encarsia sophia (Gahan) in the early 2000s. Further, E. sophia became the dominant parasitoid of B. tabaci in cotton after many years of predominance by native and exotic Eretmocerus. Apparent rates of parasitism were highly variable within and between years and averaged overall. In some years there was evidence that B. tabaci populations declined as apparent parasitism increased. Lower pest abundance was associated with higher rates of apparent parasitism over the entire 15-year period but this pattern was not supported by long term life-table based measurements of parasitism. Detailed life table studies within the entire agro-ecosystem will be needed to fully assess the impact of the classical biological control program. Published by Elsevier Inc.

TI Carbohydrate and nutrient composition of corn stover from three southeastern USA locations SO BIOMASS & BIOENERGY LA English DT Article DE Theoretical ethanol yield; Nutrient removal; Corn; Carbohydrates; Stover removal ID RESIDUE REMOVAL; ORGANIC-MATTER; BIOMASS YIELD; SOIL; MANAGEMENT; FEEDSTOCK; TILLAGE; CROP; DEGRADATION; NITROGEN AB Corn (Zea mays L.) stover has been identified as an important feedstock for bioenergy and bio-product production. Our objective was to quantify nutrient removal, carbohydrate composition, theoretical ethanol yield (TEY) for various stover fractions. In 2009, 2010, and 2011, whole-plant samples were collected from one field study in South Carolina (SC) and two in Alabama (AL). Soils at the SC site were classified as a Coxville/Rains-Goldboro-Lynchburg association, while those in AL were either Compass or Decatur. Plants were collected from two 1-m row segments, ears were removed and shelled. A portion of the remaining stalks were dried and ground to represent whole-plant stover. The remaining stalks were fractionated into stalk and leaf biomass from below the ear (bottom), stalk and leaf biomass from above the ear (top), cobs, and grain. A fifth sample representing "above-ear" biomass that might be collected mechanically was calculated using the weight ratios of the top and cob fractions. Carbohydrate and nutrient concentrations were estimated using near-infrared spectroscopy (NIRS) and TEY was calculated. The distribution of carbohydrates, nutrients, and TEY varied significantly among the corn stover fraction and research locations. This indicates that site-specific sampling and analysis should be used to optimize bioenergy and bio-product utilization of corn stover. However, at every location, the above-ear stover fractions were most desirable for cellulosic ethanol production. Furthermore, harvesting only above-ear stover fractions would reduce nutrient removal by 24-61% when compared to harvesting all stover biomass. (C) 2015 Elsevier Ltd. All rights reserved.

In recent years, Adelphocoris suturalis has become a significant pest in transgenic Bacillus thuringiensis (Bt) cotton fields. We previously reported that virgin A. suturalis females attracted males in the field. In this study, we found that A. suturalis males are not attracted in Y-tube olfactometer bioassays to odors from either live nymphs or sexually mature virgin females whose ostioles of the metathoracic scent gland (MTG) are occluded with paraffin wax. However, males are significantly attracted to odors from adult virgin females when female abdomina are occluded with paraffin, indicating that female A. suturalis release sex pheromones only from the MTG. Volatile extracts from both sexes were collected and analyzed by gas chromatography-electroantennogram detection and gas chromatography-mass spectrometry. We identified (E)-4-oxo-2-hexenal (E4O2H), hexyl hexanoate (HH) and hexyl butyrate (HB) as major components and found that they elicited the largest EAD responses from antennae of males. Both E4O2H and HH were present in aeration extracts from females, while E4O2H was found in males. Capture of only males in field tests using synthetic compounds confirmed the activity of the identified sex pheromone candidates. In the field tests, a 10:1 ratio of the E4O2H and HH binary blend exhibited the highest efficiency in attracting male A. suturalis. Addition of HB to the binary pheromone blend to make a ternary blend did not increase trap catches. These results demonstrate that E4O2H and HH constitute the A. suturalis sex pheromone components.

A total of 13,663 sequences including 603 isolate sequences were identified in the RDP database (Release 11, Update 1), where 13,447 sequences were assigned to 10 phyla, 17 classes, 28 orders, 59 families, and 110 genera, while the remaining 216 sequences could not be assigned to a known phylum. Firmicutes and Bacteroidetes were the first and the second predominant phyla, respectively. About 41 % of the total sequences could not be assigned to a known genus. The total sequences were assigned to 1252 OTUs at 97 % sequence similarity. A small number of OTUs shared among datasets indicate that fecal bacterial communities of cattle are greatly affected by various factors, specifically diet. This study may guide future studies to further analyze fecal bacterial communities of cattle. C1 [Kim, Minseok; Wells, James.

Colony members are generally expected to benefit by optimizing the reproductive traits of prospective replacement queens, but potential conflicts of interest among colony members could result in suboptimal queens. We studied the degree to which colonies regulate adult queen traits by controlling access to developing queens that survived from pupation to adulthood. We also searched for evidence of strong conflict among patrilines by comparing the contribution of patrilines to new queens and new workers, although we found no evidence for the existence of significantly queen-biased patrilines or for any association between patriline contribution to new queens and queen traits. However, adult queens emerging from cells accessible to workers were larger in terms of compared to adult queens emerging from cells that were not accessible to workers. These results suggest that colonies regulate queen quality traits by curtailing low-quality queens from fully developing, which is further evidence that cooperation predominates over potential conflict within honey bee colonies.

After receiving seminal products, which include the systemic regulator juvenile hormone (JH), females enter a post-mating period lasting several days during which they enhance their oviposition rate and lose interest in remating. To elucidate the regulation of these behavioral changes in L. hesperus, biogenic amines were quantified in the heads of females at 5 min, 1 h and 24 h after copulation and compared to levels in virgins using high-performance liquid chromatography coupled with electrochemical detection. Mating significantly increased dopamine (DA) after 1 and 24 h, and decreased octopamine (OA) after 5 min and 1 h. Serotonin did not change with mating, but tyramine was significantly reduced after 5 min. While injection of amines into virgin females did not influence sexual receptivity, OA caused a decrease in oviposition during the 24 h following injection. Topical application of the JH analog methoprene to virgins caused an increase in DA, and a decline in mating propensity, but did not influence other amines or the oviposition rate. The results suggest the decline in OA observed immediately after mating may promote egg laying, and that male-derived JH may induce an increase in DA that could account for the post-mating loss of sexual receptivity.

In each period, cows were randomly assigned to 1 of 5 dietary treatments: (1) control (CON), consisting of a basal total mixed ration (TMR); (2) high-dose NSP diet (NSP-1%), consisting of TMR plus 230 g of NSP; (3) aflatoxin diet (AFD), consisting of the TMR plus AF challenge; (4) low-dose NSP with AF (NSP-0.5%+AFD), composed of TMR plus 115 g of NSP and AF challenge; and (5) high-dose NSP with AF (NSP-1%+AFD), consisting of TMR plus 230 g of NSP and AF challenge. The AF challenge consisted of top dressing a daily dose of 100 mu g/kg estimated, dry matter intake (DMI); similarly, NSP was fed at 1.0 or 0.5% of estimated DMI. Milk yield and DMI were similar across treatments averaging 21.1 +/- 1.33 kg/d and 19.7 +/- 0.56 kg/d, respectively. Concentration of milk fat, protein, and lactose were similar across treatments with averages of 4.91 +/- 0.20%, 3.85 +/- 0.10%, and 4.70 +/- 0.06%, respectively. Concentration of vitamin A averaged 0.28 +/- 0.03 mu g/mL and riboflavin concentration averaged 1.57 +/- 0.13 mu g/mL across treatments. The concentration of minerals in milk were similar for all treatments. Cows fed CON and NSP-1% yielded the lowest concentration of AFM1 in milk with 0.03 and 0.01 +/- 0.06 mu g/L. Addition of NSP reduced milk AFM(1). from 1.10 +/- 0.06 mu g/L with the AF diet to 0.58 and 0.32 +/- 0.06 mu g/L with the NSP-0.5%+AF and NSP-1%+AF diets, respectively. Excretion of AFM1 was reduced by NSF; mean values were 24.38, 11.86, 7.38, 0.64, and 0.23, +/- 1.71 mu g/d, for AFD, NSP-0.5%+AFD, NSP-1%+AFD, NSP-1%, and CON, respectively. More specifically, 1.07 +/- 0.08% of the daily AF intake was transferred to the milk of cows consuming the AFD, whereas the AF transfer rates in milk from cows that consumed the NSP-0.5%+AFD and NSP-1%+AFD were 0.52 and 0.32 +/- 0.08%. Results from this research demonstrate that feeding NSP to lactating cows is an effective method to reduce the transfer and excretion of AFM1 in milk with no negative effects on dry matter intake, milk production, and composition.

TI Benchmarking dairy herd health status using routinely recorded herd summary data SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE herd health status; producer-recorded data; prediction; benchmarking ID RISK-FACTORS; CLINICAL MASTITIS; MILK-PRODUCTION; LACTATING COWS; UNITED-STATES; DANISH DAIRY; HEAT-STRESS; MANAGEMENT; DISEASE; FARM AB Genetic improvement of dairy cattle health through the use of producer-recorded data has been determined to be feasible. Low estimated heritabilities indicate that genetic progress will be slow. Variation observed in lowly heritable traits can largely be attributed to nongenetic factors, such as the environment. More rapid improvement of dairy cattle health may be attainable if herd health programs incorporate environmental and managerial aspects. More than 1,100 herd characteristics are regularly recorded on farm test-days. We combined these data with producer-recorded health event data, and parametric and nonparametric models were used to benchmark herd and cow health status. Health events were grouped into 3 categories for analyses: mastitis, reproductive, and metabolic. Both herd incidence and individual incidence were used as dependent variables. Models implemented included stepwise logistic regression, support vector machines, and random forests. At both the herd and individual levels, random forest models attained the highest accuracy for predicting health status in all health event categories when evaluated with 10-fold cross-validation. Accuracy (SD) ranged from 0.61 (0.04) to 0.63 (0.04) when using random forest models at the herd level. Accuracy of prediction (SD) at the individual cow level ranged from 0.87 (0.06) to 0.93 (0.001) with random forest models. Highly significant variables and key words from logistic regression and random forest models were also investigated. All models identified several of the same key factors for each health event category, including movement out of the herd, size of the herd, and weather-related variables. We concluded that benchmarking health status using routinely collected herd data is feasible. Nonparametric models were better suited to handle this complex data with numerous variables. These data mining techniques were able to perform prediction of health status and could add evidence to personal experience in herd management. C1 [Gaddis, K. L.

Disease status, as indicated by MAP test results, was determined through quarterly ELISA serum testing, biannual fecal culture, and culture of tissues and feces at slaughter. Milk production data were collected from the Dairy Herd Information Association. Animals with positive MAP test results were categorized, based on test results over the full course of the study, as high path (at least one high-positive culture) or low path (at least one positive culture or ELISA). The cumulative numbers of positive ELISA and culture results were recorded. The effects of both MAP infection path, status, and number of positive tests on milk production were analyzed using a mixed linear model with an autocorrelation random effect structure. Low- and high-path animals produced more milk before their first positive test than always-negative animals, especially high-path animals. Although mean production decreased after a first positive test, low-path animals were shown to recover some productivity. High-path animals continued to exhibit a decrease in milk production, especially after their first high-positive fecal culture. These results show that not all animals that test positive for MAP will have long-term production losses. Milk production decreased significantly with each additional positive test. Ultimately, production loss appeared to be a function of MAP infection progression. C1 [Smith, Rebecca L.] Univ Illinois, Coll Vet Med, Dept Pathobiol, Urbana, IL 61802 USA. [Groehn, Y.

OIL; CASTOR-OIL; FATTY-ACIDS; LITHIATED ADDUCTS; IDENTIFICATION; QUANTIFICATION; HPLC; TRIRICINOLEIN; DAG AB The ratios of regioisomers of 72 molecular species of triacylglycerols (TAG) in lesquerella oil were estimated using the electrospray ionization mass spectrometry of the lithium adducts of TAG in the HPLC fractions of lesquerella oil. The ratios of ion signal intensities (or relative abundances) of the fragment ions from the neutral losses of fatty acids (FA) as alpha-lactones at the sn-2 position (MS3) of the molecular species of TAG were used as the ratios of the regioisomers. The order of the preference of FA incorporation at the sn-2 position of the molecular species of TAG in lesquerella was as: normal FA > OH18 (monohydroxy FA with 18 carbon atoms) > diOH18 > OH20 > diOH20, while in castor was as: normal FA > OH18 > OH20 > diOH18 > triOH18. Elongation (from C-18 to C-20) was more effective than hydroxylation in lesquerella to incorporate hydroxy FA at the sn-1/3 positions. The block of elongation in lesquerella may be used to increase the content of hydroxy FA, e.g., ricinoleate, at the sn-2 position of TAG and to produce triricinolein (or castor oil) for industrial uses. The content of normal FA at the sn-2 position was about 95 %, mainly oleate (38 %), linolenate (31 %) and linoleate (23 %). This high normal FA content (95 %) at the sn-2 position was a big space for the replacement of ricinoleate to increase the hydroxy FA content in lesquerella oil. The content of hydroxy FA at the sn-1/3 positions was 91 % mainly lesquerolic acid (85 %) and the content of normal FA was 6.7 % at the sn-1/3 position in lesquerella oil.

It also has wide application in consumer goods such as lipstick, deodorants and medicinal uses. Due to concerns about the possible presence of the ricin toxin in the oil, we have tested a collection of castor oils processed using different approaches, including cold-pressed, US Pharmaceutical (USP) grade, and neutralized oils. Water soluble proteins were extracted from oil samples into phosphate-buffered saline containing 0.05 % bovine serum albumin (PBSB) and analyzed for potential ricin contamination by ELISA. Our results indicate that only the cold-pressed castor oil contained measurable levels of the toxin, estimated to be 35 +/- 13 mu g/l. A normal oral dose of castor oil for laxative use is 14 ml, so even cold-pressed castor oil would be well below the toxic level of 1-5 mu g/kg body weight. However, the presence of the toxin indicates that other soluble proteins, including allergens, may be present in cold-pressed castor oil.

The importance of cAMP signalling in fungal biology has been well documented and the key conserved components, adenylate cyclase (AC) and the catalytic subunit of PKA (CPKA), have been functionally characterized. However, other genes involved in this signalling pathway and their regulation are not well understood in filamentous fungi. Here, we performed a comparative transcriptomics analysis of AC and CPKA mutants in two closely related fungi: Fusarium graminearum (Fg) and F.verticillioides (Fv). Combining available Fg transcriptomics and phenomics data, we reconstructed the Fg cAMP signalling pathway. We developed a computational program that combines sequence conservation and patterns of orthologous gene expression to facilitate global transcriptomics comparisons between different organisms. We observed highly correlated expression patterns for most orthologues (80%) between Fg and Fv. We also identified a subset of 482 (6%) diverged orthologues, whose expression under all conditions was at least 50% higher in one genome than in the other. This enabled us to dissect the conserved and unique portions of the cAMP-PKA pathway. Although the conserved portions controlled essential functions, such as metabolism, the cell cycle, chromatin remodelling and the oxidative stress response, the diverged portions had species-specific roles, such as the production and detoxification of secondary metabolites unique to each species. The evolution of the cAMP-PKA signalling pathway seems to have contributed directly to fungal divergence and niche adaptation.

TI Ephemeral gully channel width and erosion simulation technology SO NATURAL HAZARDS LA English DT Article DE Ephemeral gullies; Erosion; Sediment yield; Watersheds; Models ID MODEL; ANNAGNPS; PREDICTION AB Concentrated surface runoff, such as associated with ephemeral gully channels, increases erosion and transfers fine sediment and associated agrichemicals from upland areas to stream channels. Ephemeral gully erosion on cropland may contribute up to 40 % or more of the sediment delivered to the edge of agricultural fields, significantly threatening the health of downstream ecological services. Typically, conservation practices developed for sheet and rill erosion are also expected to treat ephemeral gully erosion, but technology and tools are needed to account for the separate benefits and effects of practices on various sediment sources. Without improved research studies, subjective observations will continue to be used to satisfy quality criteria in lieu of scientifically defensible, quantitative methods to estimate the impact of gully erosion. Ephemeral gully channels evolve by one, or combination of, complex physical process in the form of incision, headcut migration upslope, and channel sidewalls expansion (widening). This study focused on the latter, ephemeral gully channel widening relationships. The impact of various width functions on erosion can be very significant and is dependent on discharge, slope, soil properties, and management conditions. A description is provided on six ephemeral gully widening relationships, followed by recommended improvements, comparative application, and identification of future research needs. Improvements in the development of ephemeral gully width algorithms are critical to understanding the impact of conservation practices on controlling ephemeral gully erosion. Tools are needed to predict and quantify ephemeral gully erosion, including the capability to evaluate the effect of conservation practices to control erosion. An improved critical shear stress equation was developed and described that provides an approach to incorporating impacts of management practices on the resulting gully erodibility. Conservation management planning by organizations needs a systematic approach to determining the extent of ephemeral gully erosion problems on a field, watershed, or national basis, or to predict the recurring or new locations of ephemeral gullies prior to their development.

However, effect sizes of GWA tests are small, requiring larger sample sizes to enhance power of detection of rare variants. Because of difficulties in increasing sample size in animal populations, one alternative is to implement a meta-analysis (MA), combining information and results from independent GWA studies. Although this methodology has been used widely in human genetics, implementation in animal breeding has been limited. Thus, we present methods to implement a MA of GWA, describing the proper approach to compute weights derived from multiple genomic evaluations based on animal-centric GBLUP models. Application to real datasets shows that MA increases power of detection of associations in comparison with population-level GWA, allowing for population structure and heterogeneity of variance components across populations to be accounted for. Another advantage of MA is that it does not require access to genotype data that is required for a joint analysis. Scripts related to the implementation of this approach, which consider the strength of association as well as the sign, are distributed and thus account for heterogeneity in association phase between QTL and SNPs. Thus, MA of GWA is an attractive alternative to summarizing results from multiple genomic studies, avoiding restrictions with genotype data sharing, definition of fixed effects and different scales of measurement of evaluated traits.

TI Wood decomposition as influenced by invertebrates SO BIOLOGICAL REVIEWS LA English DT Article DE arthropods; biodiversity; ecosystem services; insects; Isoptera; saproxylic ID FUNGUS-GROWING TERMITES; TROPICAL RAIN-FOREST; CORD-FORMING FUNGI; NITROGEN-FIXATION; LITTER DECOMPOSITION; CELLULOSE DIGESTION; DECAYING WOOD; COLEOPTERA CERAMBYCIDAE; NUTRIENT CONCENTRATIONS; TERRESTRIAL ECOSYSTEMS AB The diversity and habitat requirements of invertebrates associated with dead wood have been the subjects of hundreds of studies in recent years but we still know very little about the ecological or economic importance of these organisms. The purpose of this review is to examine whether, how and to what extent invertebrates affect wood decomposition in terrestrial ecosystems. Three broad conclusions can be reached from the available literature. First, wood decomposition is largely driven by microbial activity but invertebrates also play a significant role in both temperate and tropical environments. Primary mechanisms include enzymatic digestion (involving both endogenous enzymes and those produced by endo- and ectosymbionts), substrate alteration (tunnelling and fragmentation), biotic interactions and nitrogen fertilization (i.e. promoting nitrogen fixation by endosymbiotic and free-living bacteria). Second, the effects of individual invertebrate taxa or functional groups can be accelerative or inhibitory but the cumulative effect of the entire community is generally to accelerate wood decomposition, at least during the early stages of the process (most studies are limited to the first 2-3years). Although methodological differences and design limitations preclude meta-analysis, studies aimed at quantifying the contributions of invertebrates to wood decomposition commonly attribute 10-20% of wood loss to these organisms. Finally, some taxa appear to be particularly influential with respect to promoting wood decomposition. These include large wood-boring beetles (Coleoptera) and termites (Termitoidae), especially fungus-farming macrotermitines. The presence or absence of these species may be more consequential than species richness and the influence of invertebrates is likely to vary biogeographically.

The bulk polarity of these biochars declined with increasing HIT while the aromaticity and CO2-surface area (CO2-SA) rose. The surface OC contents of biochars were generally higher than bulk OC contents. The organic carbon (OC)-normalized CO2-SA (CO2-SA/OC) of biochars significantly correlated with the sorption coefficients (n and logK(oc)), suggesting that pore filling could dominate the sorption of tested sorbates. SWBs had higher logK(oc) values compared to MABs and WDBs, due to their higher ash contents. Additionally, the logK(oc) values for MABs was relatively greater than that for WDBs at low HTTs (<= 400 degrees C), probably resulting from the higher CO2-SA/OC, ash contents and aromaticity of MABs. Surface polarity and the aliphatic C may dominate the sorption of WDBs obtained at relatively low HTFs (<= 400 degrees C), while aromatic C affects the sorption of biochars at high HTFs. Results of this work aid to deepen our understanding of the sorption mechanisms, which is pivotal to wise utilization of biochars as sorbents for hazardous organic compounds. (C) 2015 Elsevier Ltd.

Previous studies with de-rooted shoots showed there was a consistency in the expression of TRlim, and plant response to exposure to silver, an aquaporin (AQP) inhibitor. However, it is not clear what confounding influence treatments with metal AQP inhibitors may have on AQP transcript expression. This study was undertaken to extend the observations of response to silver and zinc using intact plants. In a comparison of four genotypes, intact plants of PI 416937 were uniquely insensitive to exposure to silver and of PI 471938 were uniquely insensitive to zinc. RNA abundance of eight AQPs was measured after treatment with the AQP inhibitors. There were differences in the abundance of RNA among genotypes. There was a general trend of less change in abundance in PI 416937 following silver treatment in contrast to increased abundance in the other genotypes. This result would be consistent with little or no response in transpiration rate in the intact plants of PI 416937 following silver treatment. Following zinc treatment, there was a rapid increase in RNA abundance in PI 471938 in comparison to the other genotypes. However, the changes in AQP abundance following treatment with metal inhibitors indicates the likely interaction of direct response of AQP to metals and alternation of expression of AQP transcripts. These results indicate that the results from treatment with metal inhibitors should likely be considered only as preliminary screens from which genotypes need to be tested directly for the TRlim trait.

Changing disturbance regimes are of particular concern in this context due to their high potential impact on ecosystem structure, function and composition. Resilience-based stewardship is advocated to address these changes in ecosystem management, but its operational implementation has remained challenging. We review observed and expected changes in disturbance regimes and their potential impacts on provisioning, regulating, cultural and supporting ecosystem services, concentrating on temperate and boreal forests. Subsequently, we focus on resilience as a powerful concept to quantify and address these changes and their impacts, and present an approach towards its operational application using established methods from disturbance ecology. We suggest using the range of variability concept - characterizing and bounding the long-term behaviour of ecosystems - to locate and delineate the basins of attraction of a system. System recovery in relation to its range of variability can be used to measure resilience of ecosystems, allowing inferences on both engineering resilience (recovery rate) and monitoring for regime shifts (directionality of recovery trajectory). It is important to consider the dynamic nature of these properties in ecosystem analysis and management decision-making, as both disturbance processes and mechanisms of resilience will be subject to changes in the future. Furthermore, because ecosystem services are at the interface between natural and human systems, the social dimension of resilience (social adaptive capacity and range of variability) requires consideration in responding to changing disturbance regimes in forests.Synthesis and applications. Based on examples from temperate and boreal forests we synthesize principles and pathways for fostering resilience to changing disturbance regimes in ecosystem management. We conclude that future work should focus on testing and implementing these pathways in different contexts to make ecosystem services provisioning more robust to changing disturbance regimes and advance our understanding of how to cope with change and uncertainty in ecosystem management.

Attempts to restore herbaceous dominance may fail if the woody state is resilient or if intervention leads to an alternate, undesirable state. Restoration outcomes often hinge on biotic interactions - particularly on priority effects that inhibit or promote community reassembly. Following experimental tree removal from conifer-invaded grasslands, we documented substantial variation in community reassembly associated with the changing abundance of the native clonal sedge Carex inops L.H. Bailey subsp. inops. We explored possible mechanisms for this variation, focusing on the nature and timing of interactions between the meadow community and Carex and on how past tree influence and prescribed fire mediate the outcomes of these interactions. Meadow species increased after tree removal, but less so in burned than in unburned plots. Carex expanded dramatically after fire, particularly where past tree influence had been greater. Meadow species and Carex developed an increasingly negative association over time; pre-emption was reciprocal, but offset in time and space. Meadow species inhibited Carex through vegetative recovery in areas of limited or recent tree influence, irrespective of fire. Carex inhibited meadow reassembly in areas of greater tree influence, but only with burning.Synthesis and applications. Tree removal and fire imposed across a range of altered meadow states yielded varying outcomes, reflecting biotic interactions and species' regenerative traits that inhibited or promoted reassembly. Fire tended to destabilize the remnant meadow community and, in areas more degraded by encroachment, stimulated release of Carex, which inhibited reassembly. Knowledge of the context dependence of biotic interactions can enhance the effectiveness of restoration by establishing the bounds within which treatments produce desirable or undesirable outcomes.

Studies were conducted to determine the role of field margins containing HB and their effect on D. suzukii activity, density and distribution in an adjacent commercial red raspberry crop. One-ha plots adjacent to field margins containing HB or known non-host (NH) grass crops were established in 2011 and 2012 and replicated three times. Each plot contained two transects with monitoring traps for D. suzukii in the field margin (0 m) and spaced approximately 10 (crop boundary), 40, 70 and 100 m into the adjacent crop (n = 10 traps/plot). Field margin vegetation was treated with a 10% chicken egg white mark solution weekly from pre-harvest until the end of harvest using a cannon sprayer. Adult D. suzukii were collected from traps weekly and analysed for the presence of the egg white mark using an egg white-specific enzyme-linked immunosorbent assay (ELISA). During both years, marked flies and total flies were captured in higher numbers in HB field margins, whereas virtually no flies were captured in field margins containing no known alternative host. Similarly, more flies were captured in the crop near HB than near NH. Spatial Analysis by Distance IndicEs (SADIE) and mean D. suzukii trap captures additionally displayed significantly higher fly densities in the raspberry field near HB than near NH. These results suggest that HB may contribute to elevated D. suzukii populations and pest pressure in comparison with field margins containing no known alternate host vegetation for D. suzukii. Having closely adjacent non-crop alternate host landscapes may result in increased D. suzukii pest pressure. C1 [Klick, J.; Walton, V. M.; Dalton, D.

Complementing previous work investigating the effects of temperature on adult survival and fecundity of the invasive frugivorous pest, Drosophila suzukii (Matsumura), this study was conducted to determine the effect of humidity on D. suzukii larval development, adult survival, fecundity and reproductive status using blueberry as a host substrate. The five constant humidity levels in laboratory bioassays were 20, 33, 71, 82 and 94% RH at 20.6 +/- 0.2 degrees C. As RH increased, fecundity and longevity increased. At the higher humidity levels, RH had limited impact on mean generation times (T), larval development and eclosion times. The highest net reproductive rate (R-0 = 68) and highest intrinsic rate of population increase (r(m) = 0.17) were both recorded at 94% RH. The reproductive status of females, as indicated by the number of mature oocytes per female, was significantly greater at 82 and 94% RH, compared to 71% RH. In addition to the laboratory procedures, we correlated field trap captures over an 81-day summer period to relative humidity (RH) levels in close proximity to those traps. In the field, low ambient humidity levels resulted in decreased trap captures. A humidity-dependent population model predicted lower densities of D. suzukii relative to populations at higher humidity. This study supports the hypothesis that cultural practices that minimize lower humidity levels in crops can contribute to the management of D. suzukii. Such methods may include open pruning, drip irrigation and field floor management. C1 [Tochen, S.; Woltz, J. M.; Dalton, D. T.; Wiman, N. G.; Walton, V.

In this study, a mark-release-recapture technique was used to investigate whether 1) host or non-host plants of D. citri can act as barriers for dispersing insects and 2) presence or absence of young citrus leaves influence movement of D. citri towards citrus plants. The experimental field consisted of four circular and adjacent areas containing citrus trees, Citrus sinensis (L.) Osbeck cv. 'Hamlin', planted in concentric circles at 18, 24 and 30 m from the release centre. Insect activity was monitored by recapturing at each distance using yellow stick traps. Dense plantings of tall non-host plants of D. citri such as corn had no effect on insect dispersal towards citrus plants when compared to a shorter cover crop such as grass. In contrast, suitable host plants acted as traps decreasing movement of D. citri. Diaphorina citri dispersed at greater speeds in the absence of young leaves reaching 140 m within 6 hours after release, whereas in the presence of young leaves, individuals reached at most 60 m at 1 day after release. Results suggest that D. citri control measures may be more efficient during periods of highest vegetative activity when insects are less active. Moreover, the use of suitable host plants for D. citri as trap plants may be a potential tactic to prevent movement of insects into the crop. C1 [Tomaseto, A. F.; Lopes, J. R.

However, voluntary approaches have largely failed to improve water quality in impaired waters. This paper assesses how to increase the efficiency of voluntary conservation in the context of the Chesapeake Bay. Field-level data representative of cropland in the bay watershed are analyzed using a programming model to quantify the gains of targeting technology-based incentives and of performance-based incentives. Performance-based approaches were the most efficient. The efficiency of technology-based approaches was improved by targeting cropland with features indicative of low marginal abatement costs.

An inexpensive, loop-mediated isothermal amplification (LAMP) assay was designed to quickly detect airborne inoculum of E.necator to determine when to initiate a fungicide application programme. Field efficacy was tested in 2010 and 2011 in several commercial and research vineyards in the Willamette Valley of Oregon from pre-bud break to veraison. In each vineyard, three impaction spore traps were placed adjacent to the trunk. One trap was maintained and used by the grower to conduct the LAMP assay (G-LAMP) on-site and the other two traps were used for laboratory-conducted LAMP (L-LAMP) and quantitative PCR assay (qPCR). Using the qPCR as a gold standard, L-LAMP was comparable with qPCR in both years, and G-LAMP was comparable to qPCR in 2011. Latent class analysis indicated that qPCR had a true positive proportion of 98% in 2010 and 89% in 2011 and true negative proportion of 96% in 2010 and 64% in 2011. An average of 33 fewer fungicide applications were used when they were initiated based on spore detection relative to the grower standard practice. There were no significant differences in berry or leaf incidence between plots with fungicides initiated at detection or grower standard practice plots, suggesting that growers using LAMP to initiate fungicide applications can use fewer fungicide applications to manage powdery mildew compared to standard practices.

Studies and testing were done on the physical and mechanical properties of cellulose ester-based films incorporating essential oils (EO) from lemongrass (Cybopogon citratus), rosemary pepper (Lippia sidoides) and basil (Ocimum gratissimum) at concentrations of 10 and 20% (v/w). Results obtained showed that, in all films, the addition of the essential oil caused a decrease in the water vapor permeability due to the hydrophobic nature of the oil. The use of 20% of EO caused lower transparency of the films, although the change was not observed visually. Mechanical testing was done on cellulose acetate, cellulose acetate propionate and cellulose acetate butyrate. It was found that incorporation of lemongrass, basil and rosemary pepper EO significantly affected the Young's modulus, tensile strength and elongation at break of the cellulose ester films. The results suggested that the essential oils interacted with the polymers like plasticizers. The results were confirmed with thermal and microscopic studies. (C) 2015 Elsevier Ltd.

Recently, atypical pestiviruses ('HoBi'-like pestiviruses) were identified in batches of contaminated foetal calf serum and in naturally infected cattle with and without clinical symptoms. Here, we describe the first report of a mucosal disease-like clinical presentation (MD) associated with a 'HoBi'-like pestivirus occurring in a cattle herd. The outbreak was investigated using immunohistochemistry, antibody detection, viral isolation and RT-PCR. The sequence and phylogenetic analysis of 5'NCR, N-pro and E2 regions of the RT-PCR positive samples showed that four different 'HoBi'-like strains were circulating in the herd. The main clinical signs and lesions were observed in the respiratory and digestive systems, but skin lesions and corneal opacity were also observed. MD characteristic lesions and a pestivirus with cytopathic biotype were detected in one calf. The present study is the first report of a MD like presentation associated with natural infection with 'HoBi'-like pestivirus. This report describes the clinical signs and provides a pathologic framework of an outbreak associated with at least two different 'HoBi'-like strains. Based on these observations, it appears that these atypical pestiviruses are most likely underdiagnosed in Brazilian cattle. C1 [Weber, M. N.; Mosena, A. C. S.; Budaszewski, R. F.; Canal, C.

TI Serotype Diversity of Foot-and-Mouth-Disease Virus in Livestock without History of Vaccination in the Far North Region of Cameroon SO TRANSBOUNDARY AND EMERGING DISEASES LA English DT Article DE foot-and-mouth disease virus; Cameroon; Africa; phylogeny; serotyping; SAT2 ID KIDNEY-CELL LINE; MOLECULAR EPIDEMIOLOGY; ADAMAWA PROVINCE; CATTLE; SITE AB Little information is available about the natural cycle of foot-and-mouth disease (FMD) in the absence of control measures such as vaccination. Cameroon presents a unique opportunity for epidemiological studies because FMD vaccination is not practiced. We carried out a prospective study including serological, antigenic and genetic aspects of FMD virus (FMDV) infections among different livestock production systems in the Far North of Cameroon to gain insight into the natural ecology of the virus. We found serological evidence of FMDV infection in over 75% of the animals sampled with no significant differences of prevalence observed among the sampled groups (i.e. market, sedentary, transboundary trade and mobile). We also found antibodies reactive to five of the seven FMDV serotypes (A, O, SAT1, SAT2 and SAT3) among the animals sampled. Finally, we were able to genetically characterize viruses obtained from clinical and subclinical FMD infections in Cameroon. Serotype O viruses grouped into two topotypes (West and East Africa). SAT2 viruses grouped with viruses from Central and Northern Africa, notably within the sublineage causing the large epidemic in Northern Africa in 2012, suggesting a common origin for these viruses. This research will guide future interventions for the control of FMD such as improved diagnostics, guidance for vaccine formulation and epidemiological understanding in support of the progressive control of FMD in Cameroon.

We examined calling phenology of an assemblage of anurans in the Gran Chaco ecoregion of Bolivia by deploying automated recording devices to document nocturnally vocalizing amphibians nightly at seven ponds from 20 January 2011 until 31 October 2011. Using logistic regression, we modelled the relationships between temperature, rainfall and photoperiod with calling activity. There was a distinct seasonal effect with calling activity concentrated in the rainy season with no species detected during the dry season from June until the end of October. Calling activity was positively and significantly correlated with photoperiod in 9 of the 10 species analyzed, but there were distinct species-specific relationships associated with rainfall and temperature. All of these species utilize ephemeral ponds as breeding sites, which can account for their reliance on rainfall as an important driver in calling activity. Two prolonged breeders exhibited similar seasonal breeding patterns across the rainy season, but differed in their response to daily abiotic factors, which might be attributed to the constraints imposed by their reproductive mode. Explosive breeders needed several days of rain to elicit calling. Two pairs of congeners had distinct species-specific relationships between their calling activity and abiotic factors, even though the congeners shared the same reproductive mode, suggesting that the reproductive modes vary in the constraints imposed on calling activity. The patterns observed suggest that calling phenology of tropical anurans is determined by the interaction of exogenous factors (i.e. climatic variables) and endogenous factors (i.e. reproductive modes).

NF system showed inhibition by ammonium and was best described by Andrews model. The AMX system showed a strong inhibition by nitrite and Edwards model presented a best system representation. For DMX system, the increased substrate concentration (until 1060 mg NH3-N/L) tested was not limiting for the ammonia consumption rate and the Monod model was the best model to describe this process. The AOB and ANAMMOX sludges combined in the DMX system displayed a better activity, substrate affinity and excellent substrate tolerance than in nitrifying and ANAMMOX process. (C) 2015 Elsevier Ltd.

TI Impact of fiber source and feed particle size on swine manure properties related to spontaneous foam formation during anaerobic decomposition SO BIORESOURCE TECHNOLOGY LA English DT Article DE Manure; Foaming; Anaerobic digestion; Feedstock composition; Microbial community ID BIOGAS REACTORS; EMISSIONS; DIGESTION AB Foam accumulation in deep-pit manure storage facilities is of concern for swine producers because of the logistical and safety-related problems it creates. A feeding trial was performed to evaluate the impact of feed grind size, fiber source, and manure inoculation on foaming characteristics. Animals were fed: (1) C-SBM (corn-soybean meal): (2) C-DDGS (corn-dried distiller grains with solubles); and (3) C-Soybean Hull (corn-soybean meal with soybean hulls) with each diet ground to either fine (374 mu m) or coarse (631 mu m) particle size. Two sets of 24 pigs were fed and their manure collected. Factors that decreased feed digestibility (larger grind size and increased fiber content) resulted in increased solids loading to the manure, greater foaming characteristics, more particles in the critical particle size range (2-25 mu m), and a greater biological activity/potential.

Edward Buehlmann, Urs TI Potential for Yield Improvement in Combined Rip-First and Crosscut-First Rough Mill Processing SO BIORESOURCES LA English DT Article DE Rough mill lumber yield; Cut-up systems; Rip-first; Crosscut-first; Performance ID CUTTING-BILL REQUIREMENTS; CHARACTER-MARKED FURNITURE; LUMBER YIELD; DESIGN; PERFORMANCE; INCREASE; PARTS AB Traditionally, lumber cutting systems in rough mills have either first ripped lumber into wide strips and then crosscut the resulting strips into component lengths (rip-first), or first crosscut the lumber into component lengths, then ripped the segments to the required widths (crosscut-first). Each method has its advantages and disadvantages. Crosscut-first typically works best for the production of wider components, while rip-first favors the production of narrower and longer components. Thus, whichever type of processing method is selected for a given rough mill usually depends on the characteristics of the cutting bills the mill expects to process. There is a third option, a dual-line mill that contains both ripfirst and crosscut-first processing streams. To date, such mills have been rare for a variety of reasons, complexity and cost being among them. However, dual-line systems allow the mill to respond to varying cutting bill size demands as well as to board characteristics that favor one method (rip-first or crosscut-first) over the other. Using the Rough Mill Simulator (ROMI 4), this paper examines the yield improvement potential of dual-line processing over single-system processing (i.e., rip-first or crosscut-first processing alone) for a variety of cutting bills and lumber grade mixes.

Site characteristics that have the greatest effects on soil. erosion and runoff were identified. Long term (50 years) soil erosion rates as estimated using Cs-137 method varied between 5.1 and 11.0 Mg ha(-1) y(-1) and showed significant differences between Historic Climax Plant Community and Mesquite/Native states within the State and Transition Model. Erosion rates under simulated rainfall were measured between 0.9 and 17.2 g m(-2) min(-1) at 175 mm h(-1) precipitation across all sites and varied as much as 8-fold at the same location, depending on the time of the simulation. Temporal variability of erosion rates within a site was in some cases much greater than inter-site differences. This variability was attributed to natural or management driven changes in plant community and soil characteristics. Bare soil area, an aggregate indicator for all types of cover combined, was the main controlling factor of erosion process across ecological sites. For meaningful interpretation rainfall simulation, results must be placed in the context of the range of possible vegetation and surface conditions within a given ecological site.

Little is known about its intraspecific variation. Morphological variations in needle and cone traits of P. yunnanensis were analyzed to quantify variability among and within natural populations. Seven traits were measured on 10 needles collected from 30 trees in each of the 18 sampled populations of P. yunnanensis. Four cone traits were measured in 221 individual trees from nine populations. The results showed that there were significant differences (p < 0.01) both among populations and within populations in each needle and cone trait. The proportion of phenotypic variation of nearly all needle and cone traits was over 50 % within populations, which showed trees within populations accounted for a majority of the total variation. The needle traits showed higher variability within population than cone traits. Variability in the needle traits was correlated with geo-climatic parameters (longitude, latitude, altitude, temperature, and precipitation). Needle length and the ratio of needle length to fascicle sheath length showed clinal variation in response to latitudinal and altitudinal gradients. A hierarchical classification of all populations based on needle traits led to the formation of four major groups. The findings provide important genetic information for the evaluation of variation. Moreover, it will assist in management of genetic diversity of P. yunnanensis.

We investigated southeast Michigan homeowner preferences for different styles of front yards and backyards that were more or less wooded, learning what landscape characteristics they preferred and how their preferences related to their own yard management behavior. We surveyed homeowners, who selected their most preferred front yard and backyard from a series of images and indicated what characteristics were important to their preferences. We developed a homeowner typology based on their stated preferences for more and less wooded front yards and backyards, distinguished each type by landscape characteristics that were most important to homeowners, and tested whether homeowners of each preference type managed their actual yards consistent with type. Our results show that homeowners are heterogeneous in their preferences, identifying different characteristics as important according to type, but that only mowing of their actual yard is consistent with type. We also found that both important characteristics and actual uses of homeowners' yards varied between front yards and backyards. Both homeowner types and front yard/backyard differences suggest opportunities for planning and maintaining larger urban woodlands on residential lots. (C) 2015 Elsevier B.V. All rights reserved.

Thermal degradation decomposes plastic into three fractions: gas, crude oil, and solid residue. Crude oil from non-catalytic pyrolysis is usually composed of higher boiling point hydrocarbons. The optimization of conversion parameters such as the choice of catalyst, reactor design, pyrolysis temperature, and plastic-to-catalyst ratio plays a very important role in the efficient generation of gasoline and diesel grade fuel. The use of a catalyst for thermal conversion lowers the energy required for conversion, and the catalyst choice is important for efficient fuel production. The suitable selection of catalysts can increase the yield of crude oil with lower hydrocarbon content. Co-pyrolysis of plastics with coal or shale oil improves crude oil quality by decreasing its viscosity. A large number of publications have appeared on various processes, and continued improvements and/or innovations are expected in the future. Further investigations on the catalytic systems are required in order to advance the field, particularly to enhance the added value of fuels and to minimize the use of energy. This review aims to provide both the highlights of the remarkable achievements of this field and the milestones that need to be achieved in the future. (c) 2015 Elsevier Ltd. All rights reserved.

TI Estrogenic activity and nutrient losses in surface runoff after winter manure application to small watersheds SO SCIENCE OF THE TOTAL ENVIRONMENT LA English DT Article DE E-Screen; Swine manure; Turkey litter; Frozen fields ID STEROID ESTROGENS; POULTRY LITTER; BUFFER STRIPS; 17-BETA-ESTRADIOL; SOIL; TESTOSTERONE; EFFLUENTS; DAIRY AB Confined Animal Feeding Operations generate large amounts of wastes that are land-applied to provide nutrients for crop production and return organic matter to the soil. Production practices and storage limitations often necessitate that wastes be applied to frozen and snow-covered soil. Use of application setbacks have reduced concerns related to nutrient losses in surface runoff from manure, but the estrogenic activity of runoff under these conditions has not been evaluated. Therefore, we measured and sampled surface runoff when manure was applied in the winter at a rate to meet crop N needs and measured estradiol equivalents (E(2)Eqs) using E-Screen. In year one, six small watersheds used to produce corn were evaluated, treatments: 2 no-manure controls, 2 liquid swine manure with 30-m setbacks, and 2 turkey litter with 30-m setbacks. In addition, beef manure was applied to six frozen plots of forage. For years 2 and 3, applications were repeated on the swine manure watersheds and one control watershed. E(2)Eqs and nutrient concentrations generally peaked in the first runoff event after application. The highest measured E(2)Eq (5.6 ng L-1) was in the first event after swine manure application and was less than the 8.9 ng L-1 Lowest Observable Effect Concentration (LOEC) for aquatic species and well below the concentrations measured in other studies using ELISAs to measure hormone concentrations. No runoff occurred from plots planted with forage, indicating low risk for environmental impact, and therefore plots were discontinued from study. In years 2 and 3, estrogenic activity never exceeded the Predicted No Effect Concentrations for E-2 of 2 ng L-1. When post-application runoff contained high estrogenic activity, strong correlations (R-2 0.86 to 0.96) of E(2)Eq to Ca2+, Mg2+, and K+ concentrations were observed, indicating under some condition these cations might be useful surrogates for E(2)Eq measurements.

TI Characteristics and degradation of carbon and phosphorus from aquatic macrophytes in lakes: Insights from solid-state C-13 NMR and solution P-31 NMR spectroscopy SO SCIENCE OF THE TOTAL ENVIRONMENT LA English DT Article DE Plant-derived water extractable organic matter; Nuclear magnetic resonance spectroscopy; Phosphorus; Sediment; Eutrophication ID DISSOLVED ORGANIC-MATTER; SOIL; DECOMPOSITION; SEDIMENTS; WATER; TRANSFORMATIONS; NITROGEN; SORPTION; BIOAVAILABILITY; STABILIZATION AB Water extractable organic matter (WEOM) derived from macrophytes plays an important role in biogeo-chemical cycling of nutrients, including carbon (C), nitrogen (N) and phosphorus (P) in lakes. However, reports of their composition and degradation in natural waters are scarce. Therefore, compositions and degradation of WEOM derived from six aquatic macrophytes species of Tai Lake, China, were investigated by use of solid-state C-13 NMR and solution P-31 NMR spectroscopy. Carbohydrates were the predominant constituents of WEOM fractions, followed by carboxylic acid. Orthophosphate (ortho-P) was the dominant form of P (78.7% of total dissolved P) in the water extracts, followed by monoester P (mono-P) (20.6%) and little diester P (0.65%). The proportion of mono-Pin total P species increased with the percentage of O-alkyl and O-C-O increasing in the WEOM, which is likely due to degradation and dissolution of biological membranes and RNA from aquatic plants. Whereas the proportion of mono-P decreased with alkyl-C, NCH/OCH3 and COO/N-C=O increasing, which may be owing to the insoluble compounds including C functional groups of alkyl-C, NCH/OCH3 and COO/N-C=O, such as aliphatic biopolymers, lignin and peptides. Based on the results of this study and information in the literature about water column and sediment, we propose that WEOM, dominated by polysaccharides, are the most labile and bioavailable component in debris of macrophytes. Additionally, these WEOMs would also be a potential source for bioavailable organic P (e.g., RNA, DNA and phytate) for lakes. (C) 2015 Elsevier B.V. All rights reserved.

The leaf area index (LAI, m(2) m(-2)) is an important indicator of energy, water, and carbon exchange between vegetation and the atmosphere. Remote sensing techniques are frequently used to estimate LA!, and can provide users with scalable measurements of vegetation structure and function. We tested terrestrial laser scanning (TLS) techniques to estimate LAI using structural variables such as height, canopy cover, and volume for 42 Wyoming big sagebrush (Artemisia tridentata subsp. wyomingensis Beetle & Young) shrubs across three study sites in the Snake River Plain, Idaho, USA. The TLS-derived variables were regressed against sagebrush LAI estimates calculated using specific leaf area measurements, and compared with point-intercept sampling, a field method of estimating LAI. Canopy cover estimated with the TLS data proved to be a good predictor of LAI (r(2) = 0.73). Similarly, a convex hull approach to estimate volume of the shrubs from the TLS data also strongly predicted LAI (r(2) = 0.76), and compared favorably to point-intercept sampling (r(2) =0.78), a field-based method used in rangelands. These results, coupled with the relative ease-of-use of TLS, suggest that TLS is a promising tool for measuring LAI at the shrub-level. Further work should examine the structural measures in other similar shrublands that are relevant for upscaling LAI to the plot-level (i.e., hectare) using data from TLS and/or airborne laser scanning and to regional levels using satellite-based remote sensing.

Concentration-repellency response was established using the vertical paper bioassay technique for each essential oil and compared with that of N,N-diethyl-3-methyl benzamide (DEET), a standard repellent compound present in many commercial repellent formulations. The effective concentration of DEET that repels 50 % of ticks (EC50) was estimated at 0.02 mg/cm(2), while EC(50)s of the essential oils fall between 0.113 and 0.297 mg/cm(2). Based on EC50 estimates, oregano essential oil was the most effective among all essential oils tested, followed by clove, thyme, vetiver, sandalwood, cinnamon, cedarwood, and peppermint oils. None of the tested essential oils demonstrated a level of tick repellency found with DEET. Results from this study illustrated the challenge in search for more effective natural tick repellents.

Pan, Yong-Bao TI Identification of quantitative trait loci controlling sucrose content based on an enriched genetic linkage map of sugarcane (Saccharum spp. hybrids) cultivar 'LCP 85-384' SO EUPHYTICA LA English DT Article DE Genetic linkage map; Molecular marker; Quantitative trait loci (QTL); Sucrose content; Sugarcane ID RUST RESISTANCE GENE; MICROSATELLITE MARKERS; COMPLEX TRAITS; COMMERCIAL CROSS; INTERSPECIFIC CROSS; BRASSICA-NAPUS; AFLP MARKERS; QTL ANALYSIS; SSR MARKERS; YIELD AB Sucrose content is one of the most important traits considered in sugarcane breeding. Since sugarcane cultivars possess > 100 chromosomes (2n = 100-130) and are genetically complex polyploid and aneuploids, identification of quantitative trait loci (QTLs) associated with sucrose content is considered the best option to improve sucrose content through molecular breeding. A preliminary genetic linkage map of Louisiana sugarcane cultivar 'LCP 85-384' from a previous study was enriched using 65 additional polymorphism simple-sequence-repeats (SSR) primer-pairs to identify more co-segregated and homologous groups (CGs and HGs) and QTLs controlling sucrose content. Eighty-four SSR primer-pairs produced 456 markers, of which 441 were polymorphic. Both simplex (993) and duplex (225) amplified fragment length polymorphism (AFLP) and target region amplification polymorphism (TRAP) markers reported previously were also included to construct the LCP 85-384 map. These simplex and duplex markers were assigned to 108 CGs successfully using JoinMap(A (R)). This map had a cumulative genome length of 7406.3 cM that included 675 AFLP (69.8 %), 90 TRAP (9.3 %), and 202 SSR (20.9 %) markers. The 202 SSR markers were assigned to 65 CGs and 8 HGs. Based on this map, 24 putative QTLs affecting sucrose content were identified. Five QTLs were unlinked and the other 19 QTLs were located on nine CGs within four HGs. Of these QTLs, 11 had an effect in both plant-cane (20.33 %) and first-stubble (25.68 %) crops. A higher efficiency of QTLs' identification with AFLP, TRAP and SSR markers in such a genetically complex crop, proposes its wider utility in molecular breeding in sugarcane.

Population structure analysis stratified this population into five groups with Chinese landraces in four groups. Thirty-two of 51 Chinese landraces and 24 of 27 Japanese accessions were placed in one group. Association analysis using a mixed model identified 11 markers having significant associations with FHB resistance in at least two experiments. Most of these markers coincided with known quantitative trait loci (QTL) for FHB resistance with one potentially novel QTL associated with Xgdm138-5DS and Xgwm358-5DS. Xbarc19-3AS was significant in all three experiments, and the frequency of favorable alleles was more than 53 %. Chinese landraces and Japanese accessions had more favorable alleles at the majority of reproducible marker loci. Nine QTL combinations were identified according to the number of favorable alleles. Mean FHB severities increased with decreasing numbers of favorable alleles at reproducible loci. The resistance loci characterized here will further diversify the wheat FHB resistance gene pool, and provide breeders with additional sources of resistance for improvement of FHB resistance in wheat.

'Truman' winter wheat, developed and released by the University of Missouri has excellent broad-based FHB resistance in a superior soft red winter wheat background. This research identified QTL associated with greenhouse type II resistance and field resistance for incidence, severity, Fusarium damaged kernels (FDK), and deoxynivalenol (DON) based on phenotypic data collected in Missouri, Kentucky and Indiana. Two years of replicated phenotypic data were collected on a set of 167 recombinant inbred lines. Genetic linkage maps were constructed using 160 SSR and 530 DArT polymorphic markers. Across years, QTL for type II resistance were identified on chromosomes 1BSc, 2BL, 2DS and 3BSc, for incidence on 2ASc, 2DS, and 3DS and for severity on 2DS and 3BSc. QTL were also detected for incidence on 1DLc and 2DS and for severity on 1BL, 3AL and 3BLC from data collected in Indiana and Kentucky, respectively. Common QTL for FDK on chromosomes 2ASc and 3BLc and for DON on chromosomes 2ASc and 2DS were identified from data from both Missouri and Kentucky, respectively with additional individual QTL for FDK and DON identified from tests at each independent location. All alleles were from Truman and associated with significant reductions in the respective traits. QTL on 2ASC, 2DS and 3DS may be novel and once further validated, should diversify the FHB gene pool globally and be useful for enhancing FHB resistance through marker assisted selection.

Various independent systems of CPM race determination and denomination are used worldwide, having to date been differentiated on different cultivars or lines of melon (Cucumis melo L.). We briefly review historical perspectives and the current state of understanding of the virulence variation of the two CPM pathogens at the pathogenic race level, their differentiation and their designation. Furthermore, we propose for use by the international CPM research, breeding, seed and production community new tools to enhance research, communication and management of CPM. These tools consist of five components: 1) a set of 21 differential genotypes of Cucumis melo L. for the identification of CPM races; 2) a triple-part, septet code for meaningful, concise designation of CPM races; 3) protocols for maintaining CPM isolates and differential genotypes and for laboratory assays to examine the virulence of CPM isolates; 4) rules and principles of practical application of this system in breeding, seed production and cucurbit growing, including a proposal of a race denomination suitable for practical application; and 5) crucial activities leading to the implementation and running of new tools for CPM research and management. The five components of this package have equal importance, forming a compact system, and none of them can be omitted.

Methane (CH4) emissions were highest in sites with highest soil moisture (wetlands) and low water flow rates, whereas carbon dioxide (CO2) emission peaked in sites with intermediate soil moisture (riparian zone). Nitrous oxide (N2O) emissions were highest in the cropland and riparian zones, although soil genetic and chemical data suggest a difference in N2O sources between these two sites. Denitrification gene (nosZ) abundances indicate denitrification-derived N2O products in intermittently-flooded sites, while soil [NO3 +NO2] concentrations suggest nitrification-derived N2O products in dry cultivated sites. Vegetation reduced gas emissions in riparian zone habitat, but had no effect in wetland habitat. Substantial and consistent differences in gas emission rates between two neighboring wetlands corresponded to differences in flow regime. Wetland hydrologic flow regime is the factor regulating the distinct gas emission differences observed between two neighboring wetlands. This study demonstrates the importance of hydrologic factors and location-specific vegetation on gas emission hotspots in this intensively-managed agricultural landscape. (C) 2015 Elsevier B.V.

SO JOURNAL OF ARID ENVIRONMENTS LA English DT Article DE Plant establishment; Restoration; Temperature; Water potential ID SOIL; RESTORATION; TEMPERATURE; PRODUCTIVITY; HYDROCARBONS; TECHNOLOGIES; METAANALYSIS; FERTILITY; BLACK AB Direct seeding is a common large-scale restoration practice for revegetating arid and semi-arid lands, but success can be limited by moisture and temperature. Seed coating technologies that use biochar may have the potential to overcome moisture and temperature limitations on native plant germination and growth. Biochar is a popular agronomic tool for improving soil properties, such as water availability and nutrient retention and has been recently marketed, but not tested, as a seed coating. We analyzed the effect of biochar seed coating thicknesses on the germination and growth of four plant species native to western United States: mountain brome (Bromus marginatus), prairie junegrasss (Koeleria cristata), Wyeth's buckwheat (Eriogonum heracleoides), and western yarrow (Achillea millefolium). Across different temperature and water potential treatments using environmental chambers and polyethylene glycol (PEG) solutions, biochar coating applied at different thicknesses had either a neutral or negative effect on germination for all species. In the field, biochar seed coatings slightly improved mountain brome root weight and prairie junegrass cover. Our results, alongside the high economic expense of native plant seed and direct seeding operations, suggest that biochar, by itself, may not be an appropriate seed coating for improving native plant establishment.

The pedigree information can be tracked through the use of Passive Integrated Transponder (PIT) tags. However, PIT tags can be expensive, and cannot be used with small fish. DNA markers offer an alternative approach for pedigree tracking and microsatellites have been previously used for parentage assignments in rainbow trout. Single nucleotide polymorphisms (SNPs) are becoming increasingly popular in aquaculture research because they are highly abundant and are amenable for high throughput genotyping. The objectives of this study were to develop a SNP panel for parentage assignment in rainbow trout and to evaluate the accuracy of parentage assignment using fish with known pedigrees. Two groups of SNPs were targeted: 1) genome SNPs distributed across all 29 chromosomes; and 2) previously identified trait-associated SNPs. Among the 128 SNPs selected for assay development, 102 (79.7%) working assays were developed. A panel of 95 SNP assays including 68 genome SNPs and 27 trait-associated SNPs was used to genotype 499 fish with known pedigrees from Troutlodge, Inc. and from the USDA/ARS National Center for Cool and Cold Water Aquaculture. Parentage assignments matched perfectly with the known pedigrees when all 95 SNPs were used. Near perfect parentage assignment was obtained with the 68 genome SNPs, and the accuracy of parentage assignment was over 98% with a subset of 48 genome SNPs. Therefore, these SNP assays are robust and enable accurate parentage analysis in populations that are typically used in rainbow trout breeding programs.

To the extent possible, the replacement diets were formulated using currently published amino acid availabilities for the ingredients of interest in order to estimate and supplement the first two limiting amino acids (Met and Lys) to match levels in the FM control diet. The test diets were formulated to contain 35% digestible protein. Fish were fed three times daily all they would consume in 30 min. All performance measures were quadratic with respect to PBM: SBM ratio in the diet. The highest weight gain, lowest average daily feed intake, lowest feed conversion, and greatest specific growth rate coincided with a dietary PBM: SBM ratio of 1.22 to 1.35 suggesting that the best tilapia performance in the current trial was achieved with replacement formula D3 that contained approximately 20% SBM, 30% PBM, and supplemental Lys, Met, and Tau. However, all growth performance measures were significantly linear and decreased with respect to increasing distance from the ideal protein amino acid profile for tilapia. Positive effects of taurine supplementation at the highest level of dietary plant protein inclusion were not observed and may have been overwhelmed by imbalances in other amino acids in the test diets. The current results provide evidence that total deviation from the ideal protein profile in tilapia is an important consideration for diet formulation when combinations of diet ingredients are used. Hence, the essential amino acid content of a fish meal control diet may be an inadequate target for optimizing fish meal replacement diets for tilapia; whereas the whole body or muscle amino acid pattern may be a more useful formulation target. Finally, while the database of ingredients that have been evaluated in tilapia is growing, the industry will benefit from more efficient diets as long-term averages of amino acid composition and digestibility accrue for a variety of traditional and novel ingredients. Statement of Relevance: The current results provide evidence that it is the total deviations from a postulated ideal protein profile that is a more important consideration for diet formulation than the combination of diet ingredients used to meet that profile. Therefore, it should be possible to formulate least-cost fish meal replacement diets for tilapia, irrespective of ingredient combinations, and diet intact protein level, as long as a reasonable amino acid model is chosen and a fairly robust set of ingredient composition and digestibility data are available.

This was done in order to explore the potential for pyrolysis oil combustion in industrial and residential furnaces. The liquid samples investigated were bio-oil blends with ethanol (EtOH), neat ethanol and diesel. The bio-oil:EtOH blends were prepared in concentrations of 20:80 and 40:60 vol%. Twin-fluid externally mixed nozzles SU2, SU4, and SU5 with liquid orifice areas of 0.40, 1.82 and 5.07 mm(2), respectively, were used in the spray experiments. The liquid and atomizing air flow rates as well as temperature were controlled to maintain constant liquid flow rates (cc/s) equivalent to 30 and 50 kW energy input. Images of atomized spray droplets were measured to determine their size and velocity. Results show that it is possible to spray bio-oil/ethanol mixtures containing up to 40% bio-oil that has a low water content (12.60%). High viscosity and a tendency to coagulate were the main drawbacks; however, the 20:80 bio-oil: EtOH blend and neat ethanol in all three nozzles exhibited spray characteristics similar to that of diesel over atomization air flow rates of 15-30 SLPM.

The antifungal activity of the EOs was assessed by the minimum inhibitory concentration (MIC) using 96-well microplate analysis. The interactions between different EO combinations were done by the checkerboard technique. The highest antifungal activity was exhibited by oregano and thyme which showed lower MIC values amongst all the tested fungi. The antifungal activity of the other EOs could be appropriately ranked in a descending sequence of cinnamon, peppermint, tea tree and basil. Eucalyptus and mandarin showed the least efficiency as they could not inhibit any of the fungal growth at 10,000 ppm. The interaction between these two EOs also showed no interaction on the tested species. A combined formulation of oregano and thyme resulted in a synergistic effect, showing enhanced efficiency against A. flavus and A. parasiticus and P. chrysogenum. Mixtures of peppermint and tea tree produced synergistic effect against A. niger. Application of a modified Gompertz model considering fungal growth parameters like maximum colony diameter, maximum growth rate and lag time periods, under the various EO treatment scenarios, showed that the model could adequately describe and predict the growth of the tested fungi under these conditions.

The volatile organic compounds (VOCs) were analyzed with SPME-GC-MS technique. Through multivariate chemometric method, hierarchical cluster analysis (HCA) and Pearson's correlations, the CSIs: trimethylamine (TMA), ethanol (EtOH), 3-methyl-1-butanol (3Met-1But), acetoin and acetic acid (C-2) were selected from the group of 28 detected VOCs. At the moment of microbiological shelf life established at total viable count (TVC) of 7.0 log CFU/g, the CSIs achieved levels of 11.5, 38.3, 0.3, 24.0 and 90.7 mu g/g of salmon for TMA, EtOH, 3M-1But, acetoin and C-2, respectively. Pseudomonas spp. was found as major specific spoilage organism (SSOs), suitable for shelf life prediction using modified Gompertz model at the cut-off level of 6.5 log CFU/g. H2S producing bacteria and Brochothrix thermosphacta were considered as important spoilage microorganisms; however, they were not suitable for shelf life estimation. Partial least square (PLS) regression revealed possible associations between microorganisms and synthetized VOCs, showing correlations between Pseudomonas spp. and 3Met-1But and aldehydes synthesis, lactic acid bacteria were linked with EtOH, C-2 and esters, and B. thermosphacta with acetoin formation.

Eight surfactants including four soybean oil-based biosurfactants, sodium dodecyl sulfate (SDS), polyoxyethylene sorbitan monooleate (Tween 80), sophorolipid (SO) and thiamine dilauryl sulfate (TDS) at concentrations of 0.1%, 0.5% and 1.0% were tested in bacterial suspension, and the most effective biosurfactants were applied on spinach leaves. Results showed that the soybean oil-based biosurfactants, SDS or Tween 80 did not significantly affect E. coli O157:H7 populations. SO and TDS at concentrations of 1.0% were effective in reducing E. coli O157:H7 populations in bacterial suspension. E. coli O157:H7 with an initial population of 7.1 log CFU/mL was not detectable (detection limit: 1 log CFU/mL) after 1 min in 1.0% TDS or after 2 h in 1.0% SO. On spinach leaves, SO at 1% did not significantly affect E. coli when compared to a water wash during 7 days post-treatment storage at 4 degrees C. However, TDS (1.0%) wash was as effective as 200 ppm chlorine in reducing population of spot inoculated E. coli O157:H7, achieving 3.1 and 2.7 log CFU/per leaf at day 0, and 1.4 and 1.9 log CFU/leaf at day 7 when compared with a water wash. No apparent change in spinach visual quality was observed. None of treatments caused changes in visual quality of spinach. Electron micrographs suggested ultrastructural damage of bacterial cells such as separation of the outer membrane from the cytoplasmic membrane. Overall, our results showed that SO and TDS may be potential sanitizers in inactivating human pathogens such as E. coli O157:H7 in wash water and on fresh produce. Published by Elsevier Ltd.

It has been the leading bacterial cause of seafood-borne illness. This study investigated the prevalence and drug resistance of V parahaemolyticus isolated from retail shellfish in Shanghai. A total of 140 shellfish samples were collected from February 2014 to February 2015. The occurrence of V. parahaemolyticus in shellfish was 34.3%, which has increased compared to previous reports. In addition, discernible differences of total presumptive V parahaemolyticus counts (TPVPC) were also observed in shellfish between market A and B. The results from PCR assays indicated that thermostable direct hemolysin (tdh) gene was positive in two isolates (2.1%), and the thermostable direct hemolysin-related hemolysin (trh) gene was not detected in all isolates. Antibiotic resistance profiles of those isolates were as follows: ampicillin (87.5%), cephazolin (31.3%), cephalothin (6.3%), amoxicillin/clavulanic acid (6.3%), piperacillin (6.3%), and amikacin (3.2%). Thirty-three out of 96 isolates were resistant to two or more antimicrobial agents. It is suggested that V parahaemolyticus in retail shellfish could be a potential risk to consumers in Shanghai.

However, little information is available concerning the growth kinetics of C. sporogenes in food. Therefore, the objective of this study was to investigate the growth kinetics of C. sporogenes in cooked beef under different temperature conditions. Ground beef samples, inoculated with C. sporogenes spores, were incubated at temperatures between 8 and 47 degrees C to examine the growth of this microorganism. Two primary models (Huang and Baranyi models) were used to analyze the growth data. The Ratkowsky square-root model was used as the secondary model to evaluate the effect of temperature on bacterial growth rate and lag time. The USDA IPMP 2013, a free data analysis tool for predictive microbiology, was used in data analysis. No growth of C. sporogenes was observed at temperatures below 15 degrees C for up to 25 days. At temperatures between 20 and 47 degrees C, C. sporogenes grew in cooked beef. The growth curves could be analyzed by both Huang and Baranyi models. The root mean squared error (RMSE) was 0.375 for the Huang model, and 0.441 for the Baranyi model with a global 110 of 10.46. The nominal minimum growth temperature (T-0) estimated from the Huang model was 15.5 degrees C, which was 12.7 degrees C for the Baranyi model. The maximum growth temperature was 48.0 and 48.3 degrees C for the Baranyi and Huang models, respectively. The lag times and specific growth rates of C. sporogenes observed in this study were reasonably close to the data reported in the literature for C. botulinum under comparable conditions, suggesting that C. sporogenes may be used as a potential surrogate for evaluating the growth of C. botulinum in cooked meats during cooling. However, a direct comparison of growth kinetics between the two microorganisms is needed to confirm the suitability of C. sporogenes as a surrogate of C. botulinum. Published by Elsevier Ltd.

However, little research has focused on the chemical properties of wash water. Organic input from residual soil and vegetable material deteriorates water quality and creates increasing chlorine demand within this wash water. This study evaluated the origins of chlorine demand input and chlorine decay kinetics of fresh-cut produce wash water. Using a model system, vegetable juice released per kg of processed produce for shredded romaine lettuce, shredded iceberg lettuce, shredded carrot and baby spinach was 82.1 mL/kg, 94.5 mL/kg, 158 mL/kg, and 2.26 mL/kg, respectively. Batch water analysis revealed a rapid reaction between constituents in the wash water and chlorine where over a 90 min observation period, 50% of chlorine demand occurred within first 5 min, underscoring the challenge for any water treatment process to reduce chlorine demand once vegetables are deposited into washing systems. Moreover, the results also showed sustained chlorine demand over 90-min periods, indicating an accumulative effect on chlorine consumption with continuous organic input. Additionally, HPLC-SEC analysis showed that the constituents contributing to chlorine demand are predominantly dissolved small molecules (<3400 Da), which will challenge water reuse treatment approaches. This study provides quantitative information of chlorine demand origins and chlorine decay kinetics in wash water and provides baseline data critical for integrating water reuse in the fresh produce processing industry.

For this purpose, an ultra-sensitive anti-AFM(1) monoclonal antibody (MAb) 1D3 was prepared and identified. The IC50 value of the MAb 1D3 for AFM(1) was 23 ng/L, and the cross-reactivity (CR) of the MAb with aflatoxin M-2, aflatoxin B-1, aflatoxin B-2, aflatoxin G(1) and aflatoxin G(2) was 18%, 9%, <0.15%, 43% and <03%, respectively. The MAb was covalently conjugated with carboxylate-modified FMs, and the FMs were used as the label in a competitive immunochromatography assay. Using a moderate hapten-to-protein coupling ratio (2) in the coating antigen resulted in improved immunoassay sensitivity. Under optimal conditions, the IC50 value of the assay was 36.3 ng/L with the limit of detection (LOD) of 4.4 ng/L in milk samples using a fluorescence reader, and the recoveries of AFM(1) in spiked milk samples ranged from 76.6 to 110.8% with coefficient of variation (CV) of 4-14.7%. The whole procedure could be completed within 30 min. The results demonstrated that the FM-ICTS assay is easy to conduct, rapid, highly sensitive and specific for the detection of AFM(1) residues in milk. (C) 2015 Elsevier Ltd. All rights reserved.

Corn bran and oat hulls are processed to produce commercial cellulose enriched fiber gels, which generate an alkaline waste stream containing many valuable and functional components, including bio-based fiber gums. In this study, the corn bran and oat hulls processing waste streams were concentrated and drum or spray dried to produce solid products, called crude bio-based fiber gum (crude BFG). Alternatively semi-pure products (semi-pure BFG) were prepared by ethanol precipitation of the concentrated waste stream. Semi-pure product was also produced by purification of the original unconcentrated waste stream using 10, 50 and 100 kDa MWCO ultrafiltration membranes. A highly pure BFG was prepared from the unconcentrated waste stream by first adjusting its pH to 4, removing the precipitated material and precipitating the resulting supernatant with two times its volume with ethanol. All four kinds of BFGs contain arabinoxylan but with different levels of purity. The arabinoxylans have a typical structure with a slight variation in Ara/Xyl ratio showing some differences in their branching. There is a big variation in their weight average molar mass (Mw) (33-386 kDa) due to variation in the processing conditions of the waste streams. Arabinoxylans are good emulsifiers for oil-in-water emulsion systems and binding agents for petroleum coke pellets and briquettes. They are also useful antioxidants and soluble dietary fibers with antioxidant activities showing a great potential for their applications in both food and non-food industries.

In this study, composite systems consisting of starch and CFG with different molecular characteristics have been evaluated. The pasting and thermal properties, microstructure and leached amylose of corn and wheat starch have been studied. When compared with the starch suspensions alone, CFG addition led to lowering of peak viscosity, breakdown and final viscosity of corn starch. It also led to lowering of peak viscosity and final viscosity, but increase of breakdown of wheat starch The changes in rapid viscosity analyzer (RVA) characteristics were less pronounced as the M-w of CFG was increased. The amount of leached amylose of corn/wheat starch gels decreased as the M-w of CFG increased. The thermal characteristics of corn starch/CFG mixtures varied insignificantly as determined in differential scanning calorimetry (DSC) heating process. Confocal laser scanning microscopy (CLSM) confirmed changes in gel microstructure as starch components tended to be inhibited from leaching out of the granules. CFG addition also led to a well-defined morphology of wheat starch granules after gelatinization, suggesting a leaching-inhibition effect of CFG on the granule structure. (C) 2015 Elsevier Ltd.

They also play an important role in absorbing CO2 as a global carbon sink. However, unsustainable management of rangelands has led to their degradation hugely by downgrading their potential agro-ecological, environmental and socio-economical roles. This paper reviewed the rangeland degradation in Central Asia, a topic which so far has received only scant coverage in the international scientific literature. It also provided examples of successful experiences and outlined possible options that land managers can adopt to enhance the sustainable management of these vast degraded rangelands. The experiences and lessons described in this paper may also be relevant for other degraded rangeland areas, especially in the developing countries. The causes of rangeland degradation within the Central Asian region are numerous, complex and inter-related. Therefore, while addressing the factors associated with improper rangeland management may shed some light on the causes of rangeland degradation, the scope of this paper would not be all-encompassing for the major causes of degradation. There is a need to develop and widely apply the viable and locally accepted and adapted packages of technical, institutional and policy options for sustainable rangeland management. Incentivizing the collective action of small-scale pastoralists who group together to facilitate access to remote pastures can reduce the degree of overgrazing within community pastures, such as those near the settlements. We also found that migratory grazing through pooling of resources among small-scale pastoralists can increase household income. After their independence, most Central Asian countries adopted various rangeland tenure arrangements. However, the building of enhanced capacities of pasture management and effective local rangeland governance structures can increase the likelihood, which will be sustainable and equitable. Finally, this paper presented several promising technical options, aiming at reversing the trend of rangeland degradation in Central Asia.

In the preliminary research, bamboo pellets showed a low bulk density which could not meet requirement of Pellet Fuels Institute Standard Specification for Residential/Commercial Densified (PFI). To improve its bulk density, pellets were manufactured using mixtures of bamboo and pine particles and the properties were investigated. It was found that adding pine particles to bamboo particles was an effective way to improve bulk density of bamboo pellets. When adding 40% pine particles to bamboo particles, bulk density of pellets increased from 0.54 g/cm(3) to 0.60 g/cm(3), meeting grade requirement of PF1 utility. Furthermore, length, diameter and inorganic ash of pellets were also improved. Fine contents of pellets decreased from premium grade to utility grade according to PFI standard. Net calorific value also slightly decreased but it could meet the requirement of DIN 51731 (>17,500 J/g). The effect of this interaction on bulk density, inorganic ash, Net calorific value, combustion rate and heat release rate were significant. The results from this research will be very helpful to develop bamboo pellets and provide guidelines for further research. (C) 2015 Elsevier Ltd. All rights reserved.

The bioavailability of free lutein and PLGA-NP lutein in rats was assessed by determining plasma pharmacokinetics and deposition in selected tissues. Lutein uptake and secretion was also assessed in Caco-2 cells. Compared to free lutein, PLGA-NP increased the maximal plasma concentration (Cm) and area under the time-concentration curve in rats by 54.5- and 77.6-fold, respectively, while promoting tissue accumulation in the mesenteric fat and spleen. In comparison with micellized lutein, PLGA-NP lutein improved the C-max in rat plasma by 15.6-fold and in selected tissues by >3.8-fold. In contrast, PLGA-NP lutein had a lower uptake and secretion of lutein in Caco-2 cells by 10.0- and 50.5-fold, respectively, compared to micellized lutein. In conclusion, delivery of lutein with polymeric NP may be an approach to improve the bioavailability of lutein in vivo. (C) 2015 Elsevier Ltd. All rights reserved.

TI Linking thermal imaging to physiological indicators in Carica papaya L. under different watering regimes SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE Papaya; Thermography; Crop-water status monitoring; Deficit irrigation ID CHLOROPHYLL-FLUORESCENCE; DEFICIT IRRIGATION; STOMATAL CLOSURE; PLANT-RESPONSES; USE EFFICIENCY; STRESS; GRAPEVINE; DROUGHT; CROP; ECOPHYSIOLOGY AB Water deficit is the most limiting factor for yield and fruit-quality parameters in papaya crop (Carica papaya L.), deficit-irrigation (DI) strategies offering a feasible alternative to manage limiting water resources. When DI is applied, it is crucial to assess the physiological status of the crop in order to maintain the plant within a threshold value of water stress so as no to affect yield or fruit-quality parameters. The aim of this work was to evaluate the feasibility of thermal imaging in young papaya plants to assess the physiological status of this crop when it is subjected to different DI regimes, studying the relationships between the changes in leaf temperature (T-leaf) and in the major physiological parameters (i.e., stomatal conductance to water vapor, g(s); transpiration, E; and net photosynthesis, A(n)). The trial was conducted in a greenhouse from March to April of 2012. Plants were grown in pots and subjected to four irrigation treatments: (1) a full irrigation treatment (control), maintained at field capacity; (2) a partial root-zone drying treatment, irrigated with 50% of the total water applied to control to only one side of roots, alternating the sides every 7 days; (3) a regulated deficit irrigation (50% of the control, applied to both sides of plant); (4) and a non-irrigated treatment, in which irrigation was withheld from both sides of the split root for 14 days, followed by full irrigation until the end of the study. Significant relationships were found between T-leaf and major physiological variables such as g(s), E and A(n). Additionally, significant relationships were found between the difference of leaf-to-air temperature (Delta Tleaf-air) and gas-exchange measurements, which were used to establish the optimum range of Delta Tleaf-air as a preliminary step to the crop-water monitoring and irrigation scheduling in papaya, using thermal imaging as the main source of information. According to the results, we conclude that thermal imaging is a promising technique to monitor the physiological status of papaya during drought conditions. (C) 2015 Elsevier B.V.

TI Simulating future climate change impacts on seed cotton yield in the Texas High Plains using the CSM-CROPGRO-Cotton model SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE Climate models; Climate change; Crop model; DSSAT; Irrigation; Seed cotton yield ID CARBON-DIOXIDE; IRRIGATION STRATEGIES; WATER; AGRICULTURE; CO2; EVAPOTRANSPIRATION; SENSITIVITY; MANAGEMENT; AUSTRALIA; RESPONSES AB The Texas High Plains (THP) region contributes to about 25% of the US cotton production. Dwindling groundwater resources in the underlying Ogallala aquifer, future climate variability and frequent occurrences of droughts are major concerns for cotton production in this region. Assessing the impacts of climate change on cotton production enables development and evaluation of irrigation strategies for efficient utilization of groundwater resources in this region. In this study, the CROPGRO-Cotton module within the Cropping System Model (CSM) that is distributed with the Decision Support System for Agrotechnology Transfer (DSSAT) was evaluated for the THP region using measured data from cotton water use efficiency experiments at Halfway over a period of four years (2010-2013). Simulated seed cotton yield matched closely with observed yield during model calibration (average percent error of 0.1) and validation (average percent error of 6.5). The evaluated model was able to accurately simulate seed cotton yield under various irrigation strategies over the four growing seasons. The evaluated CROPGRO-Cotton model was later used to simulate the seed cotton yield under historic (1971-2000) and future (2041-2070) climate scenarios projected by three climate models. On an average, when compared to historic seed cotton yield, simulated future seed cotton yield across the THP decreased within a range of 4-17% when carbon dioxide (CO2) concentration was assumed to be constant at the current level (380 ppm) under three climatic model scenarios. In contrast, when the CO2 concentration was assumed to increase from 493 ppm (in year 2041) to 635 ppm (in year 2070) according to the Intergovernmental Panel on Climate Change (IPCC) A2 emission scenario, the simulated future average seed cotton yield in the THP region increased within a range of 14-29% as compared to historic average yield. When the irrigation amount was reduced by 40% (from 100% to 60%), the average (2041-2070) seed cotton yield decreased by 37% and 39% under the constant and increasing CO2 concentration scenarios, respectively. These results imply that cotton is sensitive to atmospheric CO2 concentrations, and cotton production in the THP could potentially withstand the effects of future climate variability under moderate increases in CO2 levels if irrigation water availability remains at current levels.

Following 20 passages, the prepatent period decreased from 120 to 104 h. A series of experiments were conducted to evaluate the pathogenicity, immunogenicity and fecundity of the newly selected line. Judged by body weight gain, feed consumption and feed efficiency following infection, the attenuated line had appreciably reduced pathogenicity. Immunogenicity of the attenuated line was examined by infecting poults successively with incremental doses of 10(2), 10(3) and 10(4) oocysts at 0, 7, and 14 days of age respectively. No oocysts were detected following challenge with 5 x 10(2) oocysts, indicating that the attenuated line had retained immunogenicity. Fecundity was assessed by infecting two-week old birds with 5 x 10(2) oocysts of either parent or attenuated line. Oocyst production from 96 to 240 h post-infection showed that the patent period of the attenuated line commenced earlier and was of shorter duration than the parent line. (C) 2015 Elsevier B.V.

Although Brazil has the second largest cattle herd in the world and it is the largest exporter of beef there are no data on the presence or impact of E. bieneusi on this important population. To fill this knowledge gap, fecal specimens were collected from 452 cattle from pre-weaned calves to adult cattle in the state of Rio de Janeiro. Host factors including age, gender, dairy/beef, body composition, and fecal consistency were included in the study. Using molecular methods, E. bieneusi was found in 79/452 (17.5%) fecal specimens. This represents the first report of this parasite in Brazilian cattle. A significantly higher prevalence was found in calves less than 2 months of age (27.6%) and those 3-8 months of age (28.8%) versus heifers (14.1%) and adults (1.4%) (P < 0.05). Dairy cattle (26.2%) had a higher prevalence than beef cattle (9.7%) (P < 0.001). No correlation was found between infection and gender, body composition, and fecal consistency. Molecular characterization of the internal transcribed spacer (ITS) revealed 12 genotypes; five previously reported in cattle (BEB4, BEB8, D, EbpA and I), and seven novel genotypes (BEB11-BEB17). A phylogenetic analysis showed that 6 genotypes (D, EbpA, BEB12, BEB13, BEB15, and BEB16) identified in 18 animals clustered within the designated zoonotic Group 1 while the other 6 genotypes (I, BEB4, BEB8, BEB11, BEB14, BEB17) identified in 61 animals clustered within Group 2. The identification of genotypes in Brazilian cattle that have previously been reported in humans highlights the potential risk of zoonotic transmission and suggests that the role of cattle in transmission of human infections requires further study.

When processed into juice, however, they are less palatable, as they develop delayed bitterness when stored for a period of time. In this study the kinetics of delayed bitterness in two citrus mandarin hybrid siblings, Ambersweet' and USDA 1-105-106, was explored by sensory and instrumental analyses. In addition to the bitter limonoids, other quality factors (i.e. sugars, acids, pH, soluble solids content (SSC), titratable acidity (TA) and the ratio SSC/TA) were also measured. RESULTSThe two citrus hybrid siblings had different chemical profiles, which were perceived by taste panels. USDA 1-105-106 developed delayed bitterness when the juice was stored for more than 4h, similar to juice from Navel' oranges, but Ambersweet' did not. Bitterness in Ambersweet' was more affected by harvest maturity, as juice from earlier harvest had lower SSC but higher TA and bitter limonoids. CONCLUSIONSince juice of USDA 1-105-106 shows delayed bitterness when stored for more than 4h, this cultivar is not suitable for juice processing. Our finding that siblings can differ in chemical and sensory properties emphasize the importance of post-processing storage studies before releasing cultivars for juice. Published 2015.

The slow pace of exotic plant invasions in mountain ecosystems is likely due to a combination of low anthropogenic disturbances, low propagule supply, and extreme/steep environmental gradients. The importance of any one of these factors is debated and likely ecosystem dependent. We evaluated the importance of various correlates of plant invasions in the Wallowa Mountain Range of northeastern Oregon and explored whether non-native species distributions differed from native species along an elevation gradient. Vascular plant communities were sampled in summer 2012 along three mountain roads. Transects (n = 20) were evenly stratified by elevation (similar to 70 m intervals) along each road. Vascular plant species abundances and environmental parameters were measured. We used indicator species analysis to identify habitat affinities for non-native species. Plots were ordinated in species space, joint plots and non-parametric multiplicative regression were used to relate species and community variation to environmental variables. Non-native species richness decreased continuously with increasing elevation. In contrast, native species richness displayed a unimodal distribution with maximum richness occurring at mid-elevations. Species composition was strongly related to elevation and canopy openness. Overlays of trait and environmental factors onto non-metric multidimensional ordinations identified the montane-subalpine community transition and over-story canopy closure exceeding 60% as potential barriers to non-native species establishment. Unlike native species, non-native species showed little evidence for high-elevation or closed-canopy specialization. These data suggest that non-native plants currently found in the Wallowa Mountains are dependent on open canopies and disturbance for establishment in low and mid elevations. Current management objectives including restoration to more open canopies in dry Rocky Mountain forests, may increase immigration pressure of non-native plants from lower elevations into the montane and subalpine zones.

O-antigens are important virulence factors, targets of both the innate and adaptive immune system, and play a role in host-pathogen interactions. Because they are highly immunogenic and display antigenic specificity unique for each strain, O-antigens are the biomarkers for designating O-types. Immunologically, 185 O-serogroups and 11 OX-groups exist for classification. Conventional serotyping for O-typing entails agglutination reactions between the O-antigen and antisera generated against each O-group. The procedure is labor intensive, not always accurate, and exhibits equivocal results. In this report, we present the sequences of 71 O-antigen gene clusters (O-AGC) and a comparison of all 196 O- and OX-groups. Many of the designated O-types, applied for classification over several decades, exhibited similar nucleotide sequences of the O-AGCs and cross-reacted serologically. Some O-AGCs carried insertion sequences and others had only a few nucleotide differences between them. Thus, based on these findings, it is proposed that several of the E. coli O-groups may be merged. Knowledge of the O-AGC sequences facilitates the development of molecular diagnostic platforms that are rapid, accurate, and reliable that can replace conventional serotyping. Additionally, with the scientific knowledge presented, new frontiers in the discovery of biomarkers, understanding the roles of O-antigens in the innate and adaptive immune system and pathogenesis, the development of glycoconjugate vaccines, and other investigations, can be explored.

Joe TI De novo construction of an expanded transcriptome assembly for the western tarnished plant bug, Lygus hesperus SO GIGASCIENCE LA English DT Article DE Transcriptome; Lygus hesperus; Plant bug; Miridae; RNA-Seq; Trinity ID GENOME AB Background: The plant bug Lygus hesperus Knight is a polyphagous pest of many economically important crops. Despite its pest status, little is known about the molecular mechanisms responsible for much of the biology of this species. Earlier Lygus transcriptome assemblies were limited by low read depth, or because they focused on specific conditions. To generate a more comprehensive transcriptome, we supplemented previous datasets with new reads corresponding to specific tissues (heads, antennae, and male reproductive tissues). This transcriptome augments current Lygus molecular resources and provides the foundational knowledge critical for future comparative studies. Findings: An expanded, Trinity/based de novo transcriptome assembly for L. hesperus was generated using previously published whole body Illumina data, supplemented with 293 million bp of new raw sequencing data corresponding to five tissue-specific cDNA libraries and 11 Illumina sequencing runs. The updated transcriptome consists of 22,022 transcripts (average length of 2075 nt), 62 % of which contain complete open reading frames. Significant coverage of the BUSCO (benchmarking universal single-copy orthologs) dataset and robust metrics indicate that the transcriptome is a quality assembly with a high degree of completeness. Initial assessment of the new assembly's utility revealed that the length and abundance of transcripts predicted to regulate insect physiology and chemosensation have improved, compared with previous L. hesperus assemblies. Conclusions: This transcriptome represents a significant expansion of Lygus transcriptome data, and improves foundational knowledge about the molecular mechanisms underlying L. hesperus biology. The dataset is publically available in NCBI and GigaDB as a resource for researchers. C1 [Fabrick, Jeffrey A.; Brent, Colin S.; Hull, J.

Vespignani, Alessandro Deshpande, Alina TI The Biosurveillance Analytics Resource Directory (BARD): Facilitating the Use of Epidemiological Models for Infectious Disease Surveillance SO PLOS ONE LA English DT Article ID DECISION-MAKING; POLICY; REAL; TOOL AB Epidemiological modeling for infectious disease is important for disease management and its routine implementation needs to be facilitated through better description of models in an operational context. A standardized model characterization process that allows selection or making manual comparisons of available models and their results is currently lacking. A key need is a universal framework to facilitate model description and understanding of its features. Los Alamos National Laboratory (LANL) has developed a comprehensive framework that can be used to characterize an infectious disease model in an operational context. The framework was developed through a consensus among a panel of subject matter experts. In this paper, we describe the framework, its application to model characterization, and the development of the Biosurveillance Analytics Resource Directory (BARD; http://brd.bsvgateway.org/brd/), to facilitate the rapid selection of operational models for specific infectious/communicable diseases. We offer this framework and associated database to stakeholders of the infectious disease modeling field as a tool for standardizing model description and facilitating the use of epidemiological models.

Control of these mites in beehives is a challenge in part due to the lack of toxic agents that are specific to mites and not to the host honey bee. In searching for a specific toxic target of varroa mites, we investigated two closely related neuropeptidergic systems, tachykinin-related peptide (TRP) and natalisin (NTL), and their respective receptors. Honey bees lack both NTL and the NTL receptor in their genome sequences, providing the rationale for investigating these receptors to understand their specificities to various ligands. We characterized the receptors for NTL and TRP of V. destructor (VdNTL-R and VdTRP-R, respectively) and for TRP of A. mellifera (AmTRP-R) in a heterologous reporter assay system to determine the activities of various ligands including TRP/NTL peptides and peptidomimetics. Although we found that AmTRP-R is highly promiscuous, activated by various ligands including two VdNTL peptides when a total of 36 ligands were tested, we serendipitously found that peptides carrying the C-terminal motif-FWxxRamide are highly specific to VdTRP-R. This motif can serve as a seed sequence for designing a VdTRP-R-specific agonist.

The structures of these new putative phytoalexins were determined by analysis of H-1 and C-13 NMR, HRESIMS, MSn, and UV data. The new stilbenoids were named arahypin-13 (21), arahypin-14 (22), and arahypin-15 (23). Together with other known bioactive peanut stilbenoids that were also produced in the challenged seeds, these new compounds may play a defensive role against invasive fungi.

We compared tree seedlings grown nearby shrub canopy (canopy subplots, CS) and in open space (open subplots, OS). S. superba in CS showed greater growth, while P. elliottii and M. macclurei were lower when compared to the plants grown in the OS. The reduced levels of high-cost compounds (proteins) and increased levels of low-cost compounds (organic acids) caused reduced CC values for P. elliottii growing in CS. While, the levels of both low-cost minerals and high-cost proteins increased in CS such that CC values of S. superba were similar in OS and CS. Based on maximum photosynthetic rates, P. elliottii required a longer payback time to construct required carbon in canopy than in OS, but the opposite was true for S. superba. The information from this study can be used to evaluate the potential of different tree species in the reforestation of subtropical degraded shrublands.

We examined the prospective association of habitual SSB intake and change in visceral adipose tissue (VAT) and subcutaneous adipose tissue. Methods and Results The quantity (volume, cm(3)) and quality (attenuation, Hounsfield Unit) of abdominal adipose tissue were measured using computed tomography in 1003 participants (mean age 45.3 years, 45.0% women) at examination 1 and 2 in the Framingham's Third Generation cohort. The 2 exams were approximate to 6 years apart. At baseline, SSB and diet soda intake were assessed using a valid food frequency questionnaire. Participants were categorized into 4 groups: none to <1 serving/mo (nonconsumers), 1 serving/mo to <1 serving/week, 1 serving/week to 1 serving/d, and 1 serving/d (daily consumers) of either SSB or diet soda. After adjustment for multiple confounders including change in body weight, higher SSB intake was associated with greater change in VAT volume (P trend<0.001). VAT volume increased by 658 cm(3) (95% confidence interval [CI], 602 to 713), 649 cm(3) (95% CI, 582 to 716), 707 cm(3) (95% CI, 657 to 757), and 852 cm(3) (95% CI, 760 to 943) from nonconsumers to daily consumers. Higher SSB intake was also associated with greater decline of VAT attenuation (P trend=0.007); however, the association became nonsignificant after additional adjustment for VAT volume change. In contrast, diet soda consumption was not associated with change in abdominal adipose tissue. Conclusions Regular SSB intake was associated with adverse change in both VAT quality and quantity, whereas we observed no such association for diet soda.

TI Bait Preference of Free-Ranging Feral Swine for Delivery of a Novel Toxicant SO PLOS ONE LA English DT Article ID BOAR SUS-SCROFA; SOUTHERN TEXAS; UNITED-STATES; WILD PIGS; BIRDS; PHARMACEUTICALS; CONSUMPTION; BEHAVIOR; COLOR; HOGS AB Invasive feral swine (Sus scrofa) cause extensive damage to agricultural and wildlife resources throughout the United States. Development of sodium nitrite as a new, orally delivered toxicant is underway to provide an additional tool to curtail growth and expansion of feral swine populations. A micro-encapsulation coating around sodium nitrite is used to minimize detection by feral swine and maximize stability for the reactive molecule. To maximize uptake of this toxicant by feral swine, development a bait matrix is needed to 1) protect the micro-encapsulation coating so that sodium nitrite remains undetectable to feral swine, 2) achieve a high degree of acceptance by feral swine, and 3) be minimally appealing to non-target species. With these purposes, a field evaluation at 88 sites in south-central Texas was conducted using remote cameras to evaluate preferences by feral swine for several oil-based bait matrices including uncolored peanut paste, black-colored peanut paste, and peanut-based slurry mixed onto whole-kernel corn. These placebo baits were compared to a reference food, whole-kernel corn, known to be readily taken by feral swine (i.e., control). The amount of bait consumed by feral swine was also estimated using remote cameras and grid boards at 5 additional sites. On initial exposure, feral swine showed reduced visitations to the uncolored peanut paste and peanut slurry treatments. This reduced visitation subsided by the end of the treatment period, suggesting that feral swine needed time to accept these bait types. The black-colored peanut paste was visited equally to the control throughout the study, and enough of this matrix was consumed to deliver lethal doses of micro-encapsulated sodium nitrite to most feral swine during 1-2 feeding events. None of the treatment matrices reduced visitations by nontarget species, but feral swine dominated visitations for all matrices. It was concluded that black-colored peanut paste achieved satisfactory preference and consumption by feral swine, and no discernable preference by non-target species, compared to the other treatments.

TI Characteristics of growing media mixes and application for open-field production of strawberry (Fragaria ananassa) SO SCIENTIA HORTICULTURAE LA English DT Article DE Substrate media; Soilless strawberry cultivation; Water retention; TDR ID TIME-DOMAIN REFLECTOMETRY; MEASURING WATER-CONTENT; PHYSICAL-PROPERTIES; HYDRAULIC CHARACTERISTICS; GROWTH MEDIA; SOIL; YIELD; PEAT; IRRIGATION; GREENHOUSE AB Growing media are widely used for strawberry production in protected environments. Due to increasing restrictions on the use of soil fumigants, there is a need to investigate production of strawberry fruits in open fields using substrate media. The objectives of the study were to characterize chemical and hydraulic properties of a number of selected growing media mixes and to evaluate them in a two-year field study for strawberry production in open fields. The growing media mixes were 100% coconut coir, a peat-perlite (PP) mix, a peat-rice hull (PR) mix, and a peat-coir-rice hull (PCR) mix. Results indicated that major macro- and micro nutrient element concentrations, pH, and salinity found in these growing media, after supplemental fertilization, were in recommended ranges for strawberry production. Compared to field soil, higher water content values were found for these growing media mixes at saturation and after free drainage. Among these media mixes, 100% Coir showed the highest water content values at saturation (0.95 cm(3) cm(-3)) and after free drainage (0.51 cm(3) cm(-3)). The field study also demonstrated the most vigorous vegetative growth in Coir by showing higher values in plant canopy size and biomass dry weight. In year 1 field experiment, marketable strawberry fruit yields from Coir, PP, and PR averaged 41,640 kg ha(-1) which was not significantly different from the soil beds. Marketable strawberry yields from the year 2 Coir and PP treatments averaged 48,520 kg ha(-1), which was also not significantly different from the grower standard practice in field soils. The year 2 yield was higher than year 1 because of longer harvesting season and more favorable weather conditions for strawberry growth. The study demonstrated that certain growing media mixes such as PP or the 100% Coir possess the needed chemical and hydraulic properties for plant growth and the 100% Coir could be used as a promising substrate material for open-field production of strawberries. Additional work is needed to optimize the irrigation and fertilization regimes to reduce the volume of growing media needed per plant and to evaluate the reuse of the substrate media to reduce production cost.

'Sanibel'. Full ripe fruit were treated with either chilling (5 degrees C for 5 days), hot water (52 degrees C for 15 min, then cooled to 25 degrees C with tap water), or left untreated as the control. Fruit samples were taken directly after treatment or after 4 days storage at 20 degrees C. Directly after treatments, heating remarkably increased the activity of lipoxygenase (LOX), and chilling increased malondialdehyde (MDA) content. LOX catalyzes the oxidation of lipids, and MDA is a compound produced from lipids under oxidative stress. The increase of LOX activity and MDA content indicates escalated reactive oxygen species (ROS) in the tissues. The heat treatment also increased ascorbate levels, and induced the activities of catalase (CAT) and peroxidase (POD) as well. After 4 days storage at 20 degrees C, antioxidant reductive capacity (ARC) and the activity of ascorbate peroxidase (APX) was significantly higher in the chilling treated fruit than in the control. Chilling directly increased MDA and ascorbate levels, and led to a remarkable increase in H2O2 on day 4 after treatment. The activities of CAT and POD were lower in chilled fruit than in the control on day 4 after treatment. These results indicate that oxidative stress may be induced by chilling treatment even without visual injury on the fruit surface. Heat treatment enhanced the antioxidant enzyme system to potentially protect fruit from environment stress. (C) 2015 Elsevier B.V. All rights reserved.

TI Are We on the Right Track: Can Our Understanding of Abscission in Model Systems Promote or Derail Making Improvements in Less Studied Crops? SO FRONTIERS IN PLANT SCIENCE LA English DT Article DE abscission; shedding; seed-shatter; grape; cranberry; fonio; tomato ID FLORAL ORGAN ABSCISSION; CELL-SEPARATION PROCESSES; TOMATO FLOWER ABSCISSION; MADS-BOX GENE; ARABIDOPSIS-THALIANA; INFLORESCENCE-DEFICIENT; TRANSCRIPTION FACTOR; RICE DOMESTICATION; ZONE CELLS; EXPRESSION AB As the world population grows and resources and climate conditions change, crop improvement continues to be one of the most important challenges for agriculturalists. The yield and quality of many crops is affected by abscission or shattering, and environmental stresses often hasten or alter the abscission process. Understanding this process can not only lead to genetic improvement, but also changes in cultural practices and management that will contribute to higher yields, improved quality and greater sustainability. As plant scientists, we have learned significant amounts about this process through the study of model plants such as Arabidopsis, tomato, rice, and maize. While these model systems have provided significant valuable information, we are sometimes challenged to use this knowledge effectively as variables including the economic value of the crop, the uniformity of the crop, ploidy levels, flowering and crossing mechanisms, ethylene responses, cultural requirements, responses to changes in environment, and cellular and tissue specific morphological differences can significantly influence outcomes. The value of genomic resources for lesser-studied crops such as cranberries and grapes and the orphan crop fonio will also be considered.

TI Association of DNA Methylation at CPT1A Locus with Metabolic Syndrome in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) Study SO PLOS ONE LA English DT Article ID EPIGENOME-WIDE ASSOCIATION; INSULIN-RESISTANCE; CARNITINE; EPIGENETICS; CHROMATIN; TRAITS; GENES; RISK AB In this study, we conducted an epigenome-wide association study of metabolic syndrome (MetS) among 846 participants of European descent in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN). DNA was isolated from CD4+ T cells and methylation at similar to 470,000 cytosine-phosphate-guanine dinucleotide (CpG) pairs was assayed using the Illumina Infinium HumanMethylation450 BeadChip. We modeled the percentage methylation at individual CpGs as a function of MetS using linear mixed models. A Bonferroni-corrected P-value of 1.1 x 10(-7) was considered significant. Methylation at two CpG sites in CPT1A on chromosome 11 was significantly associated with MetS (P for cg00574958 = 2.6x10(-14) and P for cg17058475 = 1.2x10(-9)). Significant associations were replicated in both European and African ancestry participants of the Bogalusa Heart Study. Our findings suggest that methylation in CPT1A is a promising epigenetic marker for MetS risk which could become useful as a treatment target in the future.

TI Two Horizontally Transferred Xenobiotic Resistance Gene Clusters Associated with Detoxification of Benzoxazolinones by Fusarium Species SO PLOS ONE LA English DT Article ID ASPERGILLUS-KAWACHII; FUMONISIN PRODUCTION; FUNGAL ENDOPHYTES; MAIZE SEEDLINGS; BETA-LACTAMASES; VERTICILLIOIDES; PHYTOALEXINS; ECOLOGY; CORN; BIOTRANSFORMATION AB Microbes encounter a broad spectrum of antimicrobial compounds in their environments and often possess metabolic strategies to detoxify such xenobiotics. We have previously shown that Fusarium verticillioides, a fungal pathogen of maize known for its production of fumonisin mycotoxins, possesses two unlinked loci, FDB1 and FDB2, necessary for detoxification of antimicrobial compounds produced by maize, including the gamma-lactam 2-benzoxazolinone ( BOA). In support of these earlier studies, microarray analysis of F. verticillioides exposed to BOA identified the induction of multiple genes at FDB1 and FDB2, indicating the loci consist of gene clusters. One of the FDB1 cluster genes encoded a protein having domain homology to the metallo-beta-lactamase (MBL) superfamily. Deletion of this gene ( MBL1) rendered F. verticillioides incapable of metabolizing BOA and thus unable to grow on BOA-amended media. Deletion of other FDB1 cluster genes, in particular AMD1 and DLH1, did not affect BOA degradation. Phylogenetic analyses and topology testing of the FDB1 and FDB2 cluster genes suggested two horizontal transfer events among fungi, one being transfer of FDB1 from Fusarium to Colletotrichum, and the second being transfer of the FDB2 cluster from Fusarium to Aspergillus. Together, the results suggest that plant-derived xenobiotics have exerted evolutionary pressure on these fungi, leading to horizontal transfer of genes that enhance fitness or virulence.

TI Transcriptomic Determinants of Scrapie Prion Propagation in Cultured Ovine Microglia SO PLOS ONE LA English DT Article ID CREUTZFELDT-JAKOB-DISEASE; NATURAL SCRAPIE; DENDRITIC CELLS; SELENOPROTEIN P; LYMPHOID-TISSUE; NEURONAL CELLS; MESSENGER-RNA; MOUSE MODELS; EXPRESSION; PROTEIN AB Susceptibility to infection by prions is highly dependent on the amino acid sequence and host expression of the cellular prion protein (PrPC); however, cellular expression of a genetically susceptible PrPC is insufficient. As an example, it has been shown in cultured cells that permissive and resistant sublines derived from the same parental population often have similar expression levels of PrPC. Thus, additional cellular factors must influence susceptibility to prion infection. The aim of this study was to elucidate the factors associated with relative permissiveness and resistance to scrapie prions in cultured cells derived from a naturally affected species. Two closely related ovine microglia clones with different prion susceptibility, but no detectable differences in PrPC expression levels, were inoculated with either scrapie-positive or scrapie-negative sheep brainstem homogenates. Five passages post-inoculation, the transcriptional profiles of mock and infected clones were sequenced using Illumina technology. Comparative transcriptional analyses identified twenty-two differentially transcribed genes, most of which were upregulated in poorly permissive microglia. This included genes encoding for selenoprotein P, endolysosomal proteases, and proteins involved in extracellular matrix remodeling. Furthermore, in highly permissive microglia, transforming growth factor beta-induced, retinoic acid receptor response 1, and phosphoserine aminotranspherase 1 gene transcripts were upregulated. Gene Set Enrichment Analysis identified proteolysis, translation, and mitosis as the most affected pathways and supported the upregulation trend of several genes encoding for intracellular proteases and ribosomal proteins in poorly permissive microglia. This study identifies new genes potentially involved in scrapie prion propagation, corroborates results from other studies, and extends those results into another cell culture model.

Polished grains of popular rice varieties have concentration of approximately 2 mu g g(-1) iron (Fe) and 16 mu g g(-1) zinc (Zn). The HarvestPlus breeding programs for biofortified rice target 13 mu g g(-1) Fe and 28 mu g g(-1) Zn to reach approximately 30% of the estimated average requirement (EAR). Reports on engineering Fe content in rice have shown an increase up to 18 mu g g(-1) in glasshouse settings; in contrast, under field conditions, 4 mu g g(-1) was the highest reported concentration. Here, we report on selected transgenic events, field evaluated in two countries, showing 15 mu g g(-1) Fe and 45.7 mu g g(-1) Zn in polished grain. Rigorous selection was applied to 1,689 IR64 transgenic events for insert cleanliness and, trait and agronomic performances. Event NASFer-274 containing rice nicotianamine synthase (OsNAS2) and soybean ferritin (SferH-1) genes showed a single locus insertion without a yield penalty or altered grain quality. Endosperm Fe and Zn enrichment was visualized by X-ray fluorescence imaging. The Caco-2 cell assay indicated that Fe is bioavailable. No harmful heavy metals were detected in the grain. The trait remained stable in different genotype backgrounds.

When phosphomolybdic acid H3PMo12O40 (PMo12) was used as the electron and proton carrier in the anode solution with a carbon electrode, and O-2 was directly used as the final electron acceptor under the catalysis of Pt, the peak power density reached 0.96mWcm(-2), 560times higher than that of phenol-fueled microbial fuel cells (MFCs). When the cathode reaction was catalyzed by PMo12, the power density could be greatly enhanced to 5mWcm(-2). Continuous operation demonstrated that this novel fuel cell was promising as a stable electrochemical power source. Structure analysis of the lignin indicated that the hydroxyl group content was reduced whereas the carbonyl group content increased. Both condensation and depolymerization takes place during the PMo12 oxidation of lignin. C1 [Zhao, Xuebing] Tsinghua Univ, Dept Chem Engn, Beijing 100084, Peoples R China. [Zhao, Xuebing; Zhu, J.

Because larvae utilize bacteria as a food source, most taxa present in the larval substrate, e.g., manure, are digested or degraded. However, some species survive and are present as third-instar larvae begin pupation. During metamorphosis, many bacteria are again lost during histolysis of the larval gut and subsequent remodeling to produce the gut of the imago. It has been previously demonstrated that some bacterial species survive metamorphosis, being left behind in the puparium, present on the body surface, or in the gut of the emerged adult. We used a combined culture-molecular approach to identify viable microbes from managed manure residue and a wild population of house fly larvae, pupae, puparia, and adults to assess transstadial carriage. All larval (10/10), pupal (10/10), and puparial (10/10) cultures were positive for bacteria. Several bacterial species that were present in larvae also were present either in pupae or puparia. Four viable bacterial species were detectable in 6 of 10 imagoes reared from manure. Of note is the apparent transstadial carriage of Bacillus sonorensis, which has been associated with milk spoilage at dairies, and Alcaligenes faecalis, which can harbor numerous antibiotic resistance genes on farms. The potential of newly emerged flies to harbor and disseminate bacteria from managed manure on farms is an understudied risk that deserves further evaluation.

The objectives were to 1) explore transcriptional changes among sweet corn hybrids with differential yield under crowding stress, 2) identify relationships between phenotypic responses and gene expression patterns, and 3) identify groups of genes associated with yield and crowding stress tolerance. Under conditions of crowding stress, three high-yielding and three low-yielding sweet corn hybrids were grouped for transcriptional and phenotypic analyses. Transcriptional analyses identified from 372 to 859 common differentially expressed genes (DEGs) for each hybrid. Large gene expression pattern variation among hybrids and only 26 common DEGs across all hybrid comparisons were identified, suggesting each hybrid has a unique response to crowding stress. Over-represented biological functions of DEGs also differed among hybrids. Strong correlation was observed between: 1) modules with up-regulation in high-yielding hybrids and yield traits, and 2) modules with up-regulation in low-yielding hybrids and plant/ear traits. Modules linked with yield traits may be important crowding stress response mechanisms influencing crop yield. Functional analysis of the modules and common DEGs identified candidate crowding stress tolerant processes in photosynthesis, glycolysis, cell wall, carbohydrate/nitrogen metabolic process, chromatin, and transcription regulation. Moreover, these biological functions were greatly inter-connected, indicating the importance of improving the mechanisms as a network.

TI Integrative modelling reveals mechanisms linking productivity and plant species richness SO NATURE LA English DT Article ID STRUCTURAL EQUATION MODELS; NET PRIMARY PRODUCTION; ECOSYSTEM FUNCTION; BIODIVERSITY; DIVERSITY; ECOLOGY; SCALE; HYPOTHESIS; VEGETATION; SIZE AB How ecosystem productivity and species richness are interrelated is one of the most debated subjects in the history of ecology(1). Decades of intensive study have yet to discern the actual mechanisms behind observed global patterns(2,3). Here, by integrating the predictions from multiple theories into a single model and using data from 1,126 grassland plots spanning five continents, we detect the clear signals of numerous underlying mechanisms linking productivity and richness. We find that an integrative model has substantially higher explanatory power than traditional bivariate analyses. In addition, the specific results unveil several surprising findings that conflict with classical models(4-7). These include the isolation of a strong and consistent enhancement of productivity by richness, an effect in striking contrast with superficial data patterns. Also revealed is a consistent importance of competition across the full range of productivity values, in direct conflict with some (but not all) proposed models. The promotion of local richness by macroecological gradients in climatic favourability, generally seen as a competing hypothesis(8), is also found to be important in our analysis. The results demonstrate that an integrative modelling approach leads to a major advance in our ability to discern the underlying processes operating in ecological systems.

The chemical functionality of the modified CNCs was verified with ATR-FTIR analysis and elemental analysis. The selectivity for the secondary isocyanate group using dibutyl tin dilaurate (DBTDL) as the reaction catalyst was confirmed with C-13 NMR. The modified CNCs showed improvements in the onset of thermal degradation by 35 degrees C compared to the unmodified CNCs. Polyurethane composites based on IPDI and a trifunctional polyether alcohol were synthesized using unmodified (um-CNC) and modified CNCs (m-CNC). The degree of nanoparticle dispersion was qualitatively assessed with polarized optical microscopy. It was found that the modification step facilitated superior nanoparticle dispersion compared to the um-CNCs, which resulted in increases in the tensile strength and work of fracture of over 200% compared to the neat matrix without degradation of elongation at break.

TI Global Adoption of Genetically Modified (GM) Crops: Challenges for the Public Sector SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE agricultural biotechnology; genetically modified crops; regulatory assessments ID WESTERN CORN-ROOTWORM; FRUGIPERDA LEPIDOPTERA-NOCTUIDAE; FIELD-EVOLVED RESISTANCE; HORIZONTAL GENE-TRANSFER; GREEN-REVOLUTION; PESTICIDE USE; INSECT RESISTANCE; TRANSGENIC MAIZE; BT CROPS; IMPACT AB Advances in biotechnology continue to drive the development of a wide range of insect-protected, herbicide-tolerant, stress-tolerant, and nutritionally enhanced genetically modified (GM) crops, yet societal and public policy considerations may slow their commercialization. Such restrictions may disproportionately affect developing countries, as well as smaller entrepreneurial and public sector initiatives. The 2014 IUPAC International Congress of Pesticide Chemistry (San Francisco, CA, USA; August 2014) included a symposium on "Challenges Associated with Global Adoption of Agricultural Biotechnology" to review current obstacles in promoting GM crops. Challenges identified by symposium presenters included (i) poor public understanding of GM technology and the need for enhanced communication strategies, (ii) nonharmonized and prescriptive regulatory requirements, and (iii) limited experience with regulations and product development within some public sector programs. The need for holistic resistance management programs to enable the most effective use of insect-protected crops was also a point of emphasis. This paper provides details on the symposium discussion and provides background information that can be used in support of further adoption of beneficial GM crops. Overall, it emphasizes that global adoption of modern agricultural biotechnology has not only provided benefits to growers and consumers but has great potential to provide solutions to an increasing global population and diminishing agricultural land. This potential will be realized by continued scientific innovation, harmonized regulatory systems, and broader communication of the benefits of the high-yielding, disease-resistant, and nutritionally enhanced crops attainable through modern biotechnology.

Unless mitigated, the soil organic carbon and nitrogen loss resulting from removing agricultural residues for biofuel production may cause life cycle greenhouse gas emissions to surpass national policy thresholds, and thus risk non-compliance with renewable fuel policy. Strategies to mitigate soil organic carbon loss such as using nutrient and carbon-rich, and stable land amendments will lead to time-variable greenhouse gas credits. Recent studies have argued for using time-dependent rather than time-averaged radiative forcing methods for biofuel greenhouse gas accounting but few life cycle assessment studies have examined the impact of time-varying emissions of soil organic carbon using theintergovemmental Panel on Climate Change tier 3 models. This study applies a time-dependent radiative forcing approach to a 100-year time-series data set of life cycle greenhouse gas emissions for lignocellulosic ethanol that includes temporally variable soil greenhouse gas emissions. This study demonstrates that averaging soil emissions and neglecting the time when the sequestration or release occurs within a selected time horizon can lead to a 9% to over 80% overestimation of the magnitude of the effect of the mitigation strategy. This affirms that employing strategies to maintain soil organic carbon stock early within a biofuel program supports climate change mitigation. Such strategies would guide farmers to best manage soil carbon within the biofuel production life cycle. Time-dependent approaches underscore the need for early measures of greenhouse gas curtailment to support sustainable renewable biofuel and agricultural policy. (C) 2015 Elsevier Ltd.

However, the structural basis for the anticancer activity of modified pectin requires clarification. Sugar beet and citrus pectin extracts have been compared. Pectin extracted from sugar beet pulp only weakly affected the viability of colon cancer cells. Alkali treatment increased the anti-cancer effect of sugar beet pectin via an induction of apoptosis. Alkali treatment decreased the degree of esterification (DE) and increased the ratio of rhamnogalacturonan I (RGI) to homogalacturonan. Low DE per se did not play a significant role in the anti-cancer activity. However, the enzymatic removal of galactose and, to a lesser extent, arabinose from the pectin decreased the effect on cancer cells indicating that the neutral sugar-containing RGI regions are important for pectin bioactivity.

Waterborne pathogens were detected in 96% of samples collected at three Lake Michigan beaches in summer, 2010. Samples were quantified for 22 pathogens in four microbial categories (human viruses, bovine viruses, protozoa, and pathogenic bacteria). All beaches had detections of human and bovine viruses and pathogenic bacteria indicating influence of multiple contamination sources at these beaches. Occurrence ranged from 40 to 87% for human viruses, 65-87% for pathogenic bacteria, and 13-35% for bovine viruses. Enterovirus, adenovirus A, Salmonella spp., Campylobacter jejuni, bovine polyomavirus, and bovine rotavirus A were present most frequently. Variables selected in multiple regression models used to explore environmental factors that influence pathogens included wave direction, cloud cover, currents, and water temperature. Quantitative Microbial Risk Assessment was done for C. jejuni, Salmonella spp., and enteroviruses to estimate risk of infection and illness. Median infection risks for one-time swimming events were approximately 3 x 10(-5), 7 x 10(-9), and 3 x 10(-7) for C. jejuni, Salmonella spp., and enteroviruses, respectively. Results highlight the importance of investigating multiple pathogens within multiple categories to avoid underestimating the prevalence and risk of waterborne pathogens.

In newborn ruminants, cryptosporidiosis is characterized by outbreaks of diarrhea, which can result in high morbidity and economic impact. The aim of the present study was to determine the prevalence of Cryptosporidium spp. in small ruminants from the Perote municipality in Veracruz State, Mexico. One hundred and sixty small ruminants (80 sheep and 80 goats) from eight farms located in four towns of the Perote municipality were examined following a cross-sectional study design. Stool samples were analyzed by a modification of the Faust centrifugation method, and the presence of Cryptosporidium spp. oocysts was examined using a modification of the Ziehl-Neelsen staining procedure. Bivariate and multivariate analyses were used to assess the association of Cryptosporidium infection and the general characteristics of the animals studied. Results: Overall, 112 (70 %, 95 % CI: 62.3-76.9) of the 160 small ruminants sampled were infected with Cryptosporidium spp. The prevalence of Cryptosporidium spp. infection in goats was 72.5 % (95 % CI: 61.4-81.9) and in sheep 67.5 % (95 % CI: 56.1-77.6). Small ruminants aged 1 month old had the highest (88.2 %; 95 % CI: 63.6-98.5) prevalence of infection. Prevalence varied from 60 % to 85 % among herds. Animal species, age, sex, breed, farm, town or cohabitation with cattle did not influence the prevalence of Cryptosporidium infection. Conclusions: A high prevalence of infection with Cryptosporidium spp. was observed in small ruminants from the Perote municipality in Veracruz, Mexico. Infection was widely distributed among sheep and goats regardless of their age, breed or farm location. Further research is required to identify risk factors for, and to assess the veterinary public health significance of Cryptosporidium infection among sheep and goats in the Mexican state of Veracruz.

From 2005 through 2009, a total of 12 beef cattle herds and 27 free-ranging white-tailed deer (Odocoileus virginianus) were found infected in a small geographic region of northwestern Minnesota. Genotyping of isolates determined both cattle and deer shared the same strain of bTB, and it was similar to types found in cattle in the southwestern United States and Mexico. Whole genomic sequencing confirmed the introduction of this infection into Minnesota was recent, with little genetic divergence. Aggressive surveillance and management efforts in both cattle and deer continued from 2010-2012; no additional infections were discovered. Over 10,000 deer were tested and 705 whole herd cattle tests performed in the investigation of this outbreak. C1 [Glaser, Linda] Minnesota Board Anim Hlth, St Paul, MN USA.

State funding sources used during this control program included general fund dollars and additional disease control funds appropriated by the Minnesota State Legislature to the Board of Animal Health (BAH) and Department of Natural Resources (DNR). In addition to state funds, the U.S. Department of Agriculture provided funding to these two agencies (BAH, DNR) to assist in the increased program activities for this control effort. The U.S Dept. of Agriculture funding sources included funding appropriated through Congress as well as from the Commodity Credit Corporation. The additional funds provided indemnity for infected herds, contracting accredited veterinarians for live animal cattle testing, and paying federal animal health staff for temporary duty assignments to work in Minnesota on the control effort. Funding for laboratory work performed at the Minnesota Veterinary Diagnostic Laboratory was provided by state funding through the University of Minnesota. Funding for the laboratory at the National Veterinary Services Laboratory is provided by federal government funding to the US Dept. Agriculture, Animal Plant Health Inspection Service, Veterinary Services. The US Dept. Agriculture along with all state animal health agencies cooperatively developed the guidelines and requirements for the bovine tuberculosis eradication program. These requirements and guidelines were used for this disease eradication effort in Minnesota and guided the live animal testing, cattle movement data collection, and wildlife surveillance requirements. The data reported in this article was generated during this eradication effort.

This estimation is complicated because most of the hazards causing FBD are not transmitted solely by food; most have several potential exposure routes consisting of transmission from animals, by humans, and via environmental routes including water. This paper describes an expert elicitation study conducted by the FERG Source Attribution Task Force to estimate the relative contribution of food to the global burden of diseases commonly transmitted through the consumption of food. Methods and Findings We applied structured expert judgment using Cooke's Classical Model to obtain estimates for 14 subregions for the relative contributions of different transmission pathways for eleven diarrheal diseases, seven other infectious diseases and one chemical (lead). Experts were identified through international networks followed by social network sampling. Final selection of experts was based on their experience including international working experience. Enrolled experts were scored on their ability to judge uncertainty accurately and informatively using a series of subject-matter specific 'seed' questions whose answers are unknown to the experts at the time they are interviewed. Trained facilitators elicited the 5th, and 50th and 95th percentile responses to seed questions through telephone interviews. Cooke's Classical Model uses responses to the seed questions to weigh and aggregate expert responses. After this interview, the experts were asked to provide 5th, 50th, and 95th percentile estimates for the 'target' questions regarding disease transmission routes. A total of 72 experts were enrolled in the study. Ten panels were global, meaning that the experts should provide estimates for all 14 subregions, whereas the nine panels were subregional, with experts providing estimates for one or more subregions, depending on their experience in the region. The size of the 19 hazard-specific panels ranged from 6 to 15 persons with several experts serving on more than one panel. Pathogens with animal reservoirs (e.g. non-typhoidal Salmonella spp. and Toxoplasma gondii) were in general assessed by the experts to have a higher proportion of illnesses attributable to food than pathogens with mainly a human reservoir, where human-to-human transmission (e.g. Shigella spp. and Norovirus) or waterborne transmission (e.g. Salmonella Typhi and Vibrio cholerae) were judged to dominate. For many pathogens, the foodborne route was assessed relatively more important in developed subregions than in developing subregions. The main exposure routes for lead varied across subregions, with the foodborne route being assessed most important only in two subregions of the European region. Conclusions For the first time, we present worldwide estimates of the proportion of specific diseases attributable to food and other major transmission routes. These findings are essential for global burden of FBD estimates. While gaps exist, we believe the estimates presented here are the best current source of guidance to support decision makers when allocating resources for control and intervention, and for future research initiatives.

TI Persistence of F-Specific RNA Coliphages in Surface Waters from a Produce Production Region along the Central Coast of California SO PLOS ONE LA English DT Article ID MICROBIAL SOURCE TRACKING; TROPICAL URBAN CATCHMENT; ESCHERICHIA-COLI; ENTERIC VIRUSES; FECAL CONTAMINATION; RIVER WATER; WASTE-WATER; Q-BETA; SURVIVAL; BACTERIOPHAGES AB F+RNA coliphages (FRNA) are used to source-track fecal contamination and as surrogates for enteric pathogen persistence in the environment. However, the environmental persistence of FRNA is not clearly understood and necessitates the evaluation of the survival of prototype and environmental isolates of FRNA representing all four genogroups in surface waters from the central coast of California. Water temperature played a significant role in persistence-all prototype and environmental strains survived significantly longer at 10 degrees C compared to 25 degrees C. Similarly, the availability of host bacterium was found to be critical in FRNA survival. In the absence of E. coli F-amp, all prototypes of FRNA disappeared rapidly with a D-value (days for one log reduction) of < 1.2 d from water samples incubated at 25 degrees C; the longest surviving prototype was SP. However, in the presence of the host, the order of persistence at 25 degrees C was QB>MS2>SP>GA and at 10 degrees C it was QB = MS2> GA> SP. Significant differences in survival were observed between prototypes and environmental isolates of FRNA. While most environmental isolates disappeared rapidly at 25 degrees C and in the absence of the host, members of genogroups GIII and GI persisted longer with the host compared to members of GII and GIV. Consequentially, FRNA based source tracking methods can be used to detect phages from recent fecal contamination along with those that persist longer in the environment as a result of cooler temperatures and increased host presence.

SO PEERJ LA English DT Article DE Neuroptera; Chrysopidae; Chrysopa; Green lacewings; Pheromone; Sequestration; Pharmacophagy; Iridodial; Predator; Aphid ID MALE-PRODUCED PHEROMONE; AGGREGATION PHEROMONE; IRIDOID BIOSYNTHESIS; BEETLES COLEOPTERA; BIOLOGICAL-CONTROL; ATTRACTION; OCULATA; LARVAE; APHID; SEMIOCHEMISTRY AB Green lacewings (Neuroptera: Chrysopidae) are voracious predators of aphids and other small, soft-bodied insects and mites. Earlier, we identified (1R, 2S, 5R, 8R)-iridodial from wild males of the goldeneyed lacewing, Chrysopa oculata Say, which is released from thousands of microscopic dermal glands on the abdominal sterna. Iridodial-baited traps attract C. oculata and other Chrysopa spp. males into traps, while females come to the vicinity of, but do not usually enter traps. Despite their healthy appearance and normal fertility, laboratory-reared C. oculata males do not produce iridodial. Surprisingly, goldeneyed lacewing males caught alive in iridodial-baited traps attempt to eat the lure and, in Asia, males of other Chrysopa species reportedly eat the native plant, Actinidia polygama (Siebold & Zucc.) Maxim. (Actinidiaceae) to obtain the monoterpenoid, neomatatabiol. These observations suggest that Chrysopa males must sequester exogenous natural iridoids in order to produce iridodial; we investigated this phenomenon in laboratory feeding studies. Lacewing adult males fed various monoterpenes reduced carbonyls to alcohols and saturated double bonds, but did not convert these compounds to iridodial. Only males fed the common aphid sex pheromone component, (1R, 4aS, 7S, 7aR)-nepetalactol, produced (1R, 2S, 5R, 8R)-iridodial. Furthermore, although C. oculata males fed the second common aphid sex pheromone component, (4aS, 7S, 7aR)nepetalactone, did not produce iridodial, they did convert similar to 75% of this compound to the corresponding dihydronepetalactone, and wild C. oculata males collected in early spring contained traces of this dihydronepetalactone. These findings are consistent with the hypothesis that Chrysopa males feed on oviparae (the late-season pheromone producing stage of aphids) to obtain nepetalactol as a precursor to iridodial. In the spring, however, wild C. oculata males produce less iridodial than do males collected later in the season. Therefore, we further hypothesize that Asian Chrysopa eat A. polygama to obtain iridoid precursors in order to make their pheromone, and that other iridoid-producing plants elsewhere in the world must be similarly usurped by male Chrysopa species to sequester pheromone precursors.

T.castaneum larvae have a highly compartmentalized gut, with cysteine peptidases mostly in the acidic anterior part of the midgut that are critical to the early stages of food digestion. In previous studies, we described 26 putative cysteine peptidase genes in T. castaneum (types B, L, O, F, and K) located mostly on chromosomes 3, 7, 8, and 10. In the present study,we hypothesized that specific cysteinepeptidase genes could be associated with digestive functions for food processing based on comparison of gene expression profiles in different developmental stages,feeding and non-feeding. RNAS Seq was used to determine the relative expression of cysteine peptidase genes among four major developmental stages (egg, larvae, pupae, and adult) of T.castaneum. We also compared cysteine peptidase genes in T.castaneum to those in other model insects and coleopteranpests. By combining transcriptome expression, phylogenetic comparisons, responsetodietary inhibitors, and other existing data, we identified key cysteine peptidases that T.castaneum larvae and adults use for food digestion,and thus new potential targets for biologically-based control products.

TI CpG methylation differences between neurons and glia are highly conserved from mouse to human SO HUMAN MOLECULAR GENETICS LA English DT Article ID BRAIN DNA METHYLATION; GENE; DISEASE; CELLS; MICROGLIA; ASTROCYTE; PATTERNS; DIFFERENTIATION; IDENTIFICATION; EXPRESSION AB Understanding epigenetic differences that distinguish neurons and glia is of fundamental importance to the nascent field of neuroepigenetics. A recent study used genome-wide bisulfite sequencing to survey differences in DNA methylation between these two cell types, in both humans and mice. That study minimized the importance of cell type-specific differences in CpG methylation, claiming these are restricted to localized genomic regions, and instead emphasized that widespread and highly conserved differences in non-CpG methylation distinguish neurons and glia. We reanalyzed the data from that study and came to markedly different conclusions. In particular, we found widespread cell type-specific differences in CpG methylation, with a genome-wide tendency for neuronal CpG-hypermethylation punctuated by regions of glia-specific hypermethylation. Alarmingly, our analysis indicated that the majority of genes identified by the primary study as exhibiting cell type-specific CpG methylation differences were misclassified. To verify the accuracy of our analysis, we isolated neuronal and glial DNA from mouse cortex and performed quantitative bisulfite pyrosequencing at nine loci. The pyrosequencing results corroborated our analysis, without exception. Most interestingly, we found that gene-associated neuron vs. glia CpG methylation differences are highly conserved across human and mouse, and are very likely to be functional. In addition to underscoring the importance of independent verification to confirm the conclusions of genome-wide epigenetic analyses, our data indicate that CpG methylation plays a major role in neuroepigenetics, and that the mouse is likely an excellent model in which to study the role of DNA methylation in human neurodevelopment and disease.

Through active influenza A virus surveillance in US exhibition swine and whole-genome sequencing of 380 isolates, we demonstrate that exhibition swine are actively involved in the evolution of influenza A viruses, including zoonotic strains. First, frequent introduction of influenza A viruses from commercial swine populations provides new genetic diversity in exhibition pigs each year locally. Second, genomic reassortment between viruses cocirculating in exhibition swine increases viral diversity. Third, viral migration between exhibition swine in neighboring states demonstrates that movements of exhibition pigs contributes to the spread of genetic diversity. The unexpected frequency of viral exchange between commercial and exhibition swine raises questions about the understudied interface between these populations. Overall, the complexity of viral evolution in exhibition swine indicates that novel viruses are likely to continually reemerge, presenting threats to humans.

The present study investigated the evolutionary dynamics of H9N2 viruses circulating in Korea from 1996 to 2012. Our analysis of viral population dynamics revealed an increase in genetic diversity between the years 2003 and 2007, corresponding to the spread and diversification of H9N2 viruses into multiple genetic groups (named A and B), followed by a sudden decrease in 2007, which was associated with implementation of vaccination using a Clade A virus. Implementation of the H9N2 vaccination program in Korea has dramatically reduced the diversity of H9N2 virus, and only one sub-lineage of Glade B has survived, expanded, and currently circulates in Korea. In addition, the antigenic drift of this new genetic group away from the current vaccine strain suggests the need to update the vaccine seed strain. Published by Elsevier Inc.

The goal of this study was to identify genetic features unique to KM22 by comparing the genome sequence of KM22 to the laboratory reference strain RB50. To gain a broader perspective of the genetic relationship of KM22 among other B. bronchiseptica strains, selected genes of KM22 were then compared to five other B. bronchiseptica strains isolated from different hosts. Overall, the KM22 genome sequence is more similar to the genome sequences of the strains isolated from animals than the strains isolated from humans. The majority of virulence gene expression in Bordetella is positively regulated by the two-component sensory transduction system BvgAS. bopN, bvgA, fimB, and fimC were the most highly conserved BvgAS-regulated genes present in all seven strains analyzed. In contrast, the BvgAS-regulated genes present in all seven strains with the highest sequence divergence werefimN, fim2, fhaL, andfhaS. A total of eight major fimbrial subunit genes were identified in KM22. Quantitative real-time PCR data demonstrated that seven of the eight fimbrial subunit genes identified in KM22 are expressed and regulated by BvgAS. The annotation of the KM22 genome sequence, coupled with the comparative genomic analyses reported in this study, can be used to facilitate the development of vaccines with improved efficacy towards B. bronchiseptica in swine to decrease the prevalence and disease burden caused by this pathogen.

The objective of the experiment was to determine the efficacy of copper oxide wire particles (COWP) from three commercial sources and a combination of COWP and albendazole to control GIN and/or Haemonchus contortus in lambs. Naturally infected Katandin lambs in early June 2014 and 2015 were randomly assigned to receive no COWP (CON; n=9 and 12) or 2g COWP in a gel capsule as Copasure (R) (COP; n=4 and 17; Animax Ltd.), copper oxide wire form (AUS; n=7 in 2014 only; Pharmplex), Ultracruz (TM) (ULT; n=8 and 15; Santa Cruz Animal Health (TM)), no COWP and albendazole (CON+alb; n=10 in 2015 only; 15 mg/kg BW; Valbazen (R); Zoetis Animal Health), or COWP + alb (n= 7 and 11; in 2014, lambs were administered alb on day 3). Lambs grazed grass pastures as a group and were supplemented with 227 g/lamb daily of a commercial grain mix (15% crude protein) and the same amount of alfalfa pellets. Feces were collected on days 0 (day of COWP treatment), 7, and 14 for determination of fecal egg counts (FEC). Pooled (2014) or pooled treatment group feces were cultured on days 0, 7, and 14 (2015 only) to determine GIN genera. Data were analyzed using repeated measures in a mixed model, and FEC were log transformed. The predominant GIN on day 0 was H. contortus (87%) in 2014, and there was a mixed population in 2015. The mean FEC was reduced by day 7 in AUS and ULT lambs (treatment x day, P=0.001), and all of the COWP products were similar. By day 14, the AUS FEC were lower than the CON and COP groups. When examining the combination of COWP and synthetic anthelmintic, the FEC of COWP+alb were reduced to nearly 0 eggs/g (back-transformed) and lower than the other groups (treatment x day, P=0.001). The percentage of H. contortus in cultured feces was reduced to a greater extent in the COWP than CON or CON+alb groups of lambs. In a mixed GIN population, the COWP products appeared to be similar in efficacy and using a combination of COWP + alb increased the efficacy not only against H. contortus, but all GIN genera present, offering options in the face of resistance to benzimidazoles.

Besides their role as vectors of several classes of microorganisms of veterinary and public health relevance, ticks also burden human and animal populations through their obligate blood feeding habit. It is estimated that in Mexico there are around 100 tick species belonging to the Ixodidae and Argasidae families. Information is lacking on tick species that affect humans, domestic animals, and wildlife through their life cycle. This study was conducted to bridge that knowledge gap by inventorying tick species that infest humans, domestic animals and wildlife in the State of Yucatan, Mexico. Amblyomma ticks were observed as euryxenous vertebrate parasites because they were found parasitizing 17 animal species and human. Amblyomma mixtum was the most eryxenous species found in 11 different animal species and humans. Both A. mixtum and A. parvum were found parasitizing humans. Ixodes near affinis was the second most abundant species parasitizing six animal species (dogs, cats, horses, white nosed coati, white-tail deer and black vulture) and was found widely across the State of Yucatan. Ixodid tick populations may increase in the State of Yucatan with time due to animal production intensification, an increasing wildlife population near rural communities because of natural habitat reduction and fragmentation. The diversity of ticks across host taxa documented here highlights the relevance of ecological information to understand tick-host dynamics. This knowledge is critical to inform public health and veterinary programs for the sustainable control of ticks and tick-borne diseases. (C) 2015 Published by Elsevier B.V. C1 [Rodriguez-Vivas, R.

TI Improved simulation of river water and groundwater exchange in an alluvial plain using the SWAT model SO HYDROLOGICAL PROCESSES LA English DT Article DE SWAT model; landscape unit; water exchange; floodplain; Garonne River ID STREAM-AQUIFER SYSTEMS; HYPORHEIC ZONE; NITRATE CONTAMINATION; SHALLOW GROUNDWATER; RHINE FLOODPLAIN; LANDSCAPE MODEL; ORGANIC-MATTER; GARONNE RIVER; SURFACE-WATER; FLOW MODEL AB Hydrological interaction between surface and subsurface water systems has a significant impact on water quality, ecosystems and biogeochemistry cycling of both systems. Distributed models have been developed to simulate this function, but they require detailed spatial inputs and extensive computation time. The soil and water assessment tool (SWAT) model is a semi-distributed model that has been successfully applied around the world. However, it has not been able to simulate the two-way exchanges between surface water and groundwater. In this study, the SWAT-landscape unit (LU) model - based on a catena method that routes flow across three LUs (the divide, the hillslope and the valley) - was modified and applied in the floodplain of the Garonne River. The modified model was called SWAT-LUD. Darcy's equation was applied to simulate groundwater flow. The algorithm for surface water-level simulation during flooding periods was modified, and the influence of flooding on groundwater levels was added to the model. Chloride was chosen as a conservative tracer to test simulated water exchanges. The simulated water exchange quantity from SWAT-LUD was compared with the output of a two-dimensional distributed model, surface-subsurface water exchange model. The results showed that simulated groundwater levels in the LU adjoining the river matched the observed data very well. Additionally, SWAT-LUD model was able to reflect the actual water exchange between the river and the aquifer. It showed that river water discharge has a significant influence on the surface-groundwater exchanges. The main water flow direction in the river/groundwater interface was from groundwater to river; water that flowed in this direction accounted for 65% of the total exchanged water volume. The water mixing occurs mainly during high hydraulic periods. Flooded water was important for the surface-subsurface water exchange process; it accounted for 69% of total water that flowed from the river to the aquifer. The new module also provides the option of simulating pollution transfer occurring at the river/groundwater interface at the catchment scale. Copyright (C) 2015 John Wiley & Sons, Ltd.

Some notable examples include annual reproductive cycles and for poikilotherms, seasonal changes modulating growth. Increasing water temperature elevates growth rates in fishes, but increases in photoperiod regime can have similar influences even at constant temperature. Therefore, in order to understand the dynamics of growth in fish it is important to consider the background influence of photoperiod regime on gene expression differences. This study examined the influence of a declining photoperiod regime (winter solstice) compared to an increasing photoperiod regime (spring equinox) on white muscle transcriptome profiles in fast and slow-growing rainbow trout from a commercial aquaculture strain. Results: Slow-growing fish could be characterized as possessing transcriptome profiles that conform in many respects to an endurance training regime in humans. They have elevated mitochondrial and cytosolic creatine kinase expression levels and appear to suppress mTOR-signaling as evidenced by elevated TSC2 expression, and they also have elevated p53 levels. Large fish display a physiological repertoire that may be consistent with strength/resistance physiology having elevated cytoskeletal gene component expression and glycogen metabolism cycling along with higher PI3K levels. In many respects small vs. large fish match eccentric vs. concentric muscle expression patterns, respectively. Lipid metabolic genes are also more elevated in larger fish, the most notable being the G0S2 switch gene. M and Z-line sarcomere remodelling appears to be more prevalent in large fish. Twenty-three out of 26 gene families with previously reported significant SNP-based growth differences were detected as having significant expression differences. Conclusions: Larger fish display a broader array of genes showing higher expression, and their profiles are more similar to those observed in December lot fish (i.e., an accelerated growth period). Conversely, small fish display gene profiles more similar to seasonal growth decline phases (i.e., September lot fish). Overall, seasonal timing was coupled to greater differences in gene expression compared to differences associated with fish size.

Determinants of inefficiency are identified and the effects of these determinants on the daily production of controlled fire line are examined. Results indicate that the use of bulldozers and fire engines increase the production of controlled fire line, while firefighter crews do not tend to contribute to controlled fire line production. Production of controlled fire line is more efficient if it occurs along natural or built breaks, such as rivers and roads, and within areas previously burned by wildfires. However, results also indicate that productivity and efficiency of the controlled fire line are sensitive to weather, landscape and fire characteristics. (C) 2015 Elsevier Ltd. All rights reserved.

Model development and sensitivity analysis SO AGRICULTURAL AND FOREST METEOROLOGY LA English DT Article DE Calorimetric method; Cotton; Energy balance model; Irrigation; Model sensitivity; Texas ID ENERGY-BALANCE MODEL; NET-RADIATION RATIO; WATER EVAPORATION; 2-SOURCE MODEL; CANOPY; TEMPERATURE; TIME; EVAPOTRANSPIRATION; IRRIGATION; VARIABILITY AB Soil heat flux at the surface (G(0)) is strongly influenced by whether the soil is shaded or sunlit, and therefore can have large spatial variability for incomplete vegetation cover, such as across the interrows of row crops. Most practical soil-plant-atmosphere energy balance models calculate G(0) as a function of either total (R-N) or soil net radiation (R-N,R-S). Even though R-N,R-S includes sunlit and shaded conditions, this is seldom considered, even at spatial scales of a few m. In order to improve the utility of surface energy balance models designed for row crops at relatively small spatial scales, a method was developed to calculate G(0) as a function of shaded, partially sunlit, or fully sunlit R-N,R-S. Calculation of R-N,R-S was derived using a geometric approach, and G(0) was derived by the calorimetric method using measurements of soil temperature and volumetric soil water content under upland cotton (Gossypium hirsutum L.) over a wide range of canopy cover conditions. Calorimetric G(0) and calculated R-N,R-S were related by assuming their normalized values were equal at 24h time steps and in phase. The method required only a single empirical parameter, which related the 24h minimum G(0) (G(0,MIN)) to the 24h maximum R-N,R-S (R-N,R-S,R-MAX) as G(0,MIN) = a x R-N,R-S,R-MAX, and a = -0.31 was found by simple linear regression (p <0.01). Model sensitivity (S-M) of calculated G(0) was calculated for sparse, medium, and full canopy cover; nighttime, shaded, partially sunlit, and fully sunlit surface conditions; and north-south and east-west row orientations, where input values of agronomic, shortwave, and longwave input variables were varied +/- 25% of their base values. The method was most sensitive (1.0 35% of ground area burned; the highest total sediment yields (values) occurred in plots where between 66% and 100% of the soil surface burned. Our field results suggest that erosion and wildfire severity can be simultaneously mitigated through the use of masticated fuel reduction treatments or prescribed fire treatments that leave sufficient organic matter to trap sediment but have sufficiently low fuel loading and/or enough fuel discontinuity or patchiness to limit fire spread.

TI Achievable future conditions as a framework for guiding forest conservation and management SO FOREST ECOLOGY AND MANAGEMENT LA English DT Review DE Forest management; Conservation; Ecosystem services; Novel ecosystems; Achievable future conditions; Southeastern United States ID SOUTHEASTERN UNITED-STATES; WILDLAND-URBAN INTERFACE; LOWER FLINT RIVER; CLIMATE-CHANGE; ECOLOGICAL RESPONSES; FIRE; WATER; ECOSYSTEMS; DROUGHT; RISK AB We contend that traditional approaches to forest conservation and management will be inadequate given the predicted scale of social-economic and biophysical changes in the 21st century. New approaches, focused on anticipating and guiding ecological responses to change, are urgently needed to ensure the full value of forest ecosystem services for future generations. These approaches acknowledge that change is inevitable and sometimes irreversible, and that maintenance of ecosystem services depends in part on novel ecosystems, i.e., species combinations with no analog in the past. We propose that ecological responses be evaluated at landscape or regional scales using risk-based approaches to incorporate uncertainty into forest management efforts with subsequent goals for management based on Achievable Future Conditions (AFC). AFCs defined at a landscape or regional scale incorporate advancements in ecosystem management, including adaptive approaches, resilience, and desired future conditions into the context of the Anthropocene. Inherently forward looking, ACFs encompass mitigation and adaptation options to respond to scenarios of projected future biophysical, social-economic, and policy conditions which distribute risk and provide diversity of response to uncertainty. The engagement of science-management-public partnerships is critical to our risk-based approach for defining AFCs. Robust monitoring programs of forest management actions are also crucial to address uncertainty regarding species distributions and ecosystem processes. Development of regional indicators of response will also be essential to evaluate outcomes of management strategies. Our conceptual framework provides a starting point to move toward AFCs for forest management, illustrated with examples from fire and water management in the Southeastern United States. Our model is adaptive, incorporating evaluation and modification as new information becomes available and as social-ecological dynamics change. It expands on established principles of ecosystem management and best management practices (BMPs) and incorporates scenarios of future conditions. It also highlights the potential limits of existing institutional structures for defining AFCs and achieving them. In an uncertain future of rapid change and abrupt, unforeseen transitions, adjustments in management approaches will be necessary and some actions will fail. However, it is increasingly evident that the greatest risk is posed by continuing to implement strategies inconsistent with current understanding of our novel future. (C) 2015 Elsevier B.V.

TI Responses of two genetically superior loblolly pine clonal ideotypes to a severe ice storm SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Loblolly pine (Pinus taeda L.); Clone; Ice storm; Glazing; Carbon allocation; Carbon sequestration ID SOUTHERN UNITED-STATES; PLANTATION SILVICULTURE; FOREST; DAMAGE; MANAGEMENT; IMPACTS; BIOMASS; CLIMATE; TREES AB An increase in the frequency and magnitude of extreme weather events, such as major ice storms, can have severe impacts on southern forests. We investigated the damage inflicted by a severe ice storm that occurred in February 2014 on two loblolly pine (Pins taeda L.) ideotypes in Cross, South Carolina located in the southeastern coastal plain. The "narrow crown" ideotype allocates more resources to stem growth while the "broad crown" ideotype allocates more of its resources to leaf area. We sampled each clone in August of 2014 and assessed damage based on four mutually exclusive damage categories: crown damage (visual estimation of percent damage); bent bole (bending shape and angle); snapped bole (distance from ground to snapped height); and uprooted. Damage category was statistically different between clones (chi(2) = 120.36; p = 0.001); 67% of the individuals of the narrow crown ideotype suffered crown damage compared to 94% of the broad crown ideotype; 27% of the individuals of narrow crown ideotype suffered immediate mortality after the bole snapped, compared to only 3% for the broad crown. Of the individuals that incurred crown damage, the degree of damage sustained was statistically different by clonal type (F = 8.73; p < 0.01). The broad crown ideotype incurred greater crown damage than the narrow crown (38.0 +/- 1.34 and 31.8 +/- 1.6, respectively). Damage that resulted in a bent bole was minimal, with 4% for the narrow crown ideotype and 3% for the broad crown. The observed clonal differences in response to damage that incurred from an extreme ice storm may be attributed to differences in morphology and carbon allocation strategies between the two ideotypes. These differences are important to carbon sequestration projects and ideotype development in regions that are prone to extreme glazing events. (C) 2015 Elsevier B.V. All rights reserved.

TI Forest disturbance across the conterminous United States from 1985-2012: The emerging dominance of forest decline SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Landsat time series; Forest disturbance estimation; Forest decline; TimeSync; Remote sensing; Probability sampling ID MOUNTAIN PINE-BEETLE; LANDSAT TIME-SERIES; SOUTHERN ROCKY-MOUNTAINS; TREE MORTALITY; CLIMATE-CHANGE; SPATIOTEMPORAL PATTERNS; TEMPORAL PATTERNS; DETECTING TRENDS; BARK BEETLE; DROUGHT AB Evidence of shifting dominance among major forest disturbance agent classes regionally to globally has been emerging in the literature. For example, climate-related stress and secondary stressors on forests (e.g., insect and disease, fire) have dramatically increased since the turn of the century globally, while harvest rates in the western US and elsewhere have declined. For shifts to be quantified, accurate historical forest disturbance estimates are required as a baseline for examining current trends. We report annual disturbance rates (with uncertainties) in the aggregate and by major change causal agent class for the conterminous US and five geographic subregions between 1985 and 2012. Results are based on human interpretations of Landsat time series from a probability sample of 7200 plots (30 m) distributed throughout the study area. Forest disturbance information was recorded with a Landsat time series visualization and data collection tool that incorporates ancillary high-resolution data. National rates of disturbance varied between 1.5% and 4.5% of forest area per year, with trends being strongly affected by shifting dominance among specific disturbance agent influences at the regional scale. Throughout the time series, national harvest disturbance rates varied between one and two percent, and were largely a function of harvest in the more heavily forested regions of the US (Mountain West, Northeast, and Southeast). During the first part of the time series, national disturbance rates largely reflected trends in harvest disturbance. Beginning in the mid-90s, forest decline-related disturbances associated with diminishing forest health (e.g., physiological stress leading to tree canopy cover loss, increases in tree mortality above background levels), especially in the Mountain West and Lowland West regions of the US, increased dramatically. Consequently, national disturbance rates greatly increased by 2000, and remained high for much of the decade. Decline-related disturbance rates reached as high as 8% per year in the western regions during the early-2000s. Although low compared to harvest and decline, fire disturbance rates also increased in the early- to mid-2000s. We segmented annual decline-related disturbance rates to distinguish between newly impacted areas and areas undergoing gradual but consistent decline over multiple years. We also translated Landsat reflectance change into tree canopy cover change information for greater relevance to ecosystem modelers and forest managers, who can derive better understanding of forest-climate interactions and better adapt management strategies to changing climate regimes. Similar studies could be carried out for other countries where there are sufficient Landsat data and historic temporal snapshots of high-resolution imagery. Published by Elsevier B.V.

FRANCO; PONDEROSA PINE; BARK BEETLES; PRIMARY ATTRACTION; GROWTH REDUCTION; EASTERN OREGON; PORIA-WEIRII; BLACK-STAIN; SEEDLINGS; NITROGEN AB Phellinus sulphurascens (previously the Douglas-fir form of Phellinus weirii) is an important native pathogen causing laminated root rot in forests of western North America. Visual crown symptoms, or attacks by bark or ambrosia beetles appear only during advanced stages of the disease with extensive infection in the lower bole. Ethanol synthesis is one of many physiological responses in tree tissues stressed by pathogens. Ethanol, acetone and other volatiles from root tissues of healthy and diseased trees were analyzed using headspace gas chromatography. Xylem and phloem from 20 diseased trees at two western Oregon sites contained higher concentrations of ethanol, acetone, or other headspace volatiles than 20 healthy trees on one or more dates in September, November, or the following May. Root cross-sections from eight diseased trees were sampled along perpendicular transects and found to contain extremely variable ethanol concentrations, with highest xylem quantities in a 0-2 cm zone outside the infection boundary and lowest amounts inside the infection. Acetone concentrations were the opposite. Logistic regression models were built and tested to determine which volatiles could predict diseased trees. A model using xylem ethanol concentrations as the only parameter was selected and validated with measurements from 80 trees on the edges of P. sulphurascerts infection centers at two different western Oregon sites. This model successfully predicted trees with laminated root rot (78% overall correct classification and 68% for known diseased trees), but worked best for those with infections observed in both root cores and the root collar (100% correct). Early detection of P. sulphurascens infected trees remains a challenge. Our ethanol analysis method is useful for research, but provides limited benefits for identifying individual P. sulphurascens hazard trees, or for extensive ground surveys in the forest. Whether ethanol is released to the atmosphere in sufficient quantities to confirm infection before the late appearance of crown symptoms, or bark beetles remains unknown. If it is, then development of sensors capable of tree side detection requiring minimal tissue sampling would be useful in managing this disease. We also propose a mechanism for how ethanol with host monoterpenes could play a central role in pioneering bark beetle primary host selection of trees infected with this pathogen.

Understanding the processes involved is a key requirement for managing against karst rock desertification. This study used the revised Universal Soil Loss Equation (RUSLE) to estimate the annual soil erosion rates on hillslopes and compared them with Cs-137 budget in the depressions at two typical karst peak-cluster depression basins in northwest Guangxi, southwestern China. Runoff plots data were used to calibrate the slope length factor (L) of the RUSLE model by adjusting the accumulated area threshold. The RUSLE model was sensitive to the value of the threshold and required DEMs with 1 m resolution, due to the discontinuous nature of the overland flow. The average annual soil erosion rates on hillslopes simulated by the RUSLE were 0.22 and 0.10 Mg ha(-1) y(-1) 2006 through 2011 in the partially cultivated GZ1 and the undisturbed GZ2 basins, respectively. The corresponding deposition rates in the depressions agreed well with the Cs-137 records when recent changes in precipitation and land use were taken into consideration. The study suggests that attention should be given to the RUSLE-L factor when applying the RUSLE on karst hillslopes because of the discontinuous nature of runoff and significant underground seepage during storm events that effectively reduces the effects of slope length.

TI Effect of oxidant stressors and phenolic antioxidants on the ochratoxigenic fungus Aspergillus carbonarius SO JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE LA English DT Article DE Aspergillus carbonarius; ochratoxin production; oxidative stress; grapes ID OXIDATIVE STRESS; LIQUID CULTURES; IN-VITRO; BUTYLATED HYDROXYTOLUENE; AFLATOXIN BIOSYNTHESIS; FUSARIUM-GRAMINEARUM; SECTION NIGRI; GROWTH; INHIBITION; GRAPES AB BACKGROUND: There are few studies dealing with the relationship between oxidative stress and ochratoxin A (OTA) biosynthesis. In this work, we analyzed the effect of the oxidant stressor menadione and the antioxidants 3,5-di-tert-butyl-4-hydroxytoluene (BHT), catechin, resveratrol and a polyphenolic extract on growth, generation of reactive oxygen species (ROS), OTA production and gene expression of antioxidant enzymes of Aspergillus carbonarius. RESULTS: Exposure to menadione concentrations higher than 20 mu mol L-1 led to increases in ROS and OTA levels and a decrease in growth rate. Exposure to 2.5-10 mmol L-1 BHT also led to higher ROS and OTA levels, although growth rate was only affected above 5 mmol L-1. Naturally occurring concentrations of catechin, resveratrol and polyphenolic extract barely affected growth rate, but they produced widely different effects on OTA production level depending on the antioxidant concentration used. In general, gene expression of antioxidant enzymes superoxide dismutase (SOD) and peroxiredoxin (PRX) was downregulated after exposure to oxidant and antioxidant concentrations that enhanced OTA production level. CONCLUSION: Aspergillus carbonarius responds to oxidative stress, increasing OTA production. Nevertheless, the use of naturally occurring concentrations of antioxidant phenolic compounds to reduce oxidative stress is not a valid approach by itself for OTA contamination control in grapes.

TI Using cover crops in headlands of organic grain farms: Effects on soil properties, weeds and crop yields SO AGRICULTURE ECOSYSTEMS & ENVIRONMENT LA English DT Article DE Compaction; Soil properties; Turn rows; Cover cropping; Organic farms; Grain crop yield; Midwest agriculture ID ROOT-GROWTH; COMPACTION; MATTER; PHOSPHORUS; MANAGEMENT; EMERGENCE; ILLINOIS; SYSTEMS; CARBON; MANURE AB Organic producers often rely heavily on tillage for weed management, which can create compaction, especially in headlands, and favor weed growth. To address Illinois organic grain farmers' concerns, we explored the effect of cover crops in headland areas of their farms on soil properties, weeds, and yields in a participatory on-farm approach. A split-plot arrangement with two replications at each of four Illinois locations was used in two consecutive years within field areas [FA: headlands - or turn-rows - HL; non-headlands NHL] randomly selected as main plots where four cover crop treatments were randomly assigned (CC: fallow control C; forage radish FR; mix of forage radish and buckwheat FRbw; and mix of forage radish with hairy vetch and cereal rye FRhvr). Collaborating farmers planted soybean [Glycine max (L.) Merr.] in 2012 and corn (Zea mays L.) in 2013. Each fall and spring, we measured soil penetration resistance (PR), bulk density (BD), water aggregate stability (WAS), total carbon (TC), nitrate (N-NO3), ammonium (N-NH4), available phosphorus (P), and pH. Additionally, cover crop and weed growth, and cash crop yields were determined each year. Our results indicate HL areas had greater PR (+22%) and BD (+3%), as well as higher WAS (+4%), IC (+10%), P (+36%), and pH,(+7%) in comparison to NHL areas on average through the fall and spring seasons. Though FRhvr significantly reduced spring weed biomass (-30%) compared to the controls, higher density of grass weeds (+44%) were present in HL areas through spring and summer regardless of CC treatments. Due to the resilient nature of these particular Illinois soils and extreme weather pattern observations, the cover crop treatments did not alleviate compaction nor influence soil properties for the duration of this project. However, there was a trend toward lower available P in the FRhvr treatments and reduced crop yields in those treatments within the NHL areas. Though the cover crop treatments chosen for this trial did not seem to provide clear benefits, our results point toward a beneficial feedback between the weed community and the soil properties within headland areas in these organic systems.

To address the knowledge gap of how fumigant concentration in soil impacts dissipation, and thereby efficacy, this research determined the degradation characteristics of four fumigants as affected by application rate. Laboratory incubation experiments were conducted to determine degradation rates of 1,3-dichloropropene (both cis- and trans isomers), chloropicrin (CP), dimethyl disulfide (DMDS), and methyl iodide (MeI) in five agricultural soils. Fitted to pseudo first-order kinetics, the degradation rate constant (k) of CP, DMDS, and MeI decreased significantly as application rate increased while the 1,3-D isomers were the least affected by rate. Half-lives increased 12, 17, and 6-fold for CP, DMDS, and MeI, respectively, from the lowest to the highest application rate. At low application rates, the degradation rate of all fumigants in the Hueneme sandy loam soil was reduced by 50-95% in sterilized soil compared to the biologically active controls. However, this difference became much smaller or disappeared at high application rates indicating that biodegradation dominates at low concentrations but chemical degradation is more important at high concentrations. When co-applied, CP degradation was enhanced with biodegradation remained above 50%, while 1,3-D degradation was either reduced or not changed. Among the fumigants tested, the relative importance of biodegradation was DMDS > CP > MeI > 1,3-D. These results are useful for determining effective fumigation rates and for informing regulatory decisions on emission controls under different fumigation scenarios. (C) 2015 Elsevier B.V.

Differential scanning calorimetry measurements determined octadecyl ferulate to have melting/solidification phase transitions at 67 and 39 degrees C, respectively. AFM imaging shows that 5-mol% present in a lipid bilayer induced domains to form. Phase behavior measurements confirmed that octadecyl ferulate increased transition temperature of phospholipids. Fluorescence measurements demonstrated that octadecyl ferulate stabilized liposomes against leakage, maintained antioxidant capacity within liposomes, and oriented such that the feruloyl moiety remained in the hydrophilic region of the bilayer. Molecular modeling calculation indicated that antioxidant activity was mostly influenced by interactions within the bilayer. Published by Elsevier B.V.

Proximate analysis and light micrographs revealed higher migration of red rice proteins than black rice proteins to the endosperm as a result of parboiling. Parboiling reduced the ash content of red rice while no difference was determined in black rice. Gelatinized starch granules from both genotypes showed similar appearance. There was a decrease in relative crystallinity on both black and red rice subjected to parboiling, which was an indicative of crystallites disruption. Polishing removed more than 90% of free phenolics for both genotypes, while parboiling allowed the partial preservation of free phenolics content in polished rice. Parboiling induced an increase in the cooking time of red rice, but a decrease in the cooking time of black rice. (C) 2015 Elsevier Ltd. All rights reserved.

PRUNI; DNA EXTRACTION; IDENTIFICATION; PLANTS; PHYTOPLASMAS; PATHOVAR; PRIMERS AB Xanthomonas fragariae is a bacterium that causes angular leaf spot of strawberry. Asymptomatic infection is common and contributes to the difficulties in disease management. The aim of this study was to develop a loop-mediated isothermal amplification (LAMP) assay as an efficient method for detection of asymptomatic infections of X. fragariae. In addition, a new method of sample preparation was developed that allows sampling of a larger amount of plant tissue, hence increasing the detection rate in real-life samples. The sample preparation procedure includes an overnight incubation of strawberry tissues in phosphate-buffered saline (PBS), followed by a quick sample concentration and a boiling step to extract DNA for amplification. The detection limit of the LAMP assay was approximately 2x10(3') CFU/mL for pure bacteria culture and 300 CFU/mL for bacteria spiked strawberry leaf and petiole samples. LAMP provided a 2-3 fold lower detection limit than the standard qPCR assay but was faster, and more user-friendly. The LAMP assay should serve as a rapid, sensitive and cost-effective tool for detecting asymptomatic infections of X. fragariae in strawberry nursery stock and contribute to improved disease management.

RNA-Seq was performed on a pool of total RNA extracted from tomato FAZ and [AZ, at different abscission stages, followed by de novo assembly. The assembled clusters contained transcripts that are already known in the Solanaceae (SQL) genomics and NCBI databases, and over 8823 identified novel tomato transcripts of varying sizes. An AZ-specific microarray, encompassing the novel transcripts identified in this study and all known transcripts from the SQL genomics and NCBI databases, was constructed to study the abscission process. Multiple probes for longer genes and key AZ-specific genes, including antisense probes for all transcripts, make this array a unique tool for studying abscission with a comprehensive set of transcripts, and for mining for naturally occurring antisense transcripts. We focused on comparing the global transcriptomes generated from the FAZ and the [AZ to establish the divergences and similarities in their transcriptional networks, and particularly to characterize the processes and transcriptional regulators enriched in gene clusters that are differentially regulated in these two AZs. This study is the first attempt to analyze the global gene expression in different AZs in tomato by combining the RNA-Seq technique with oligonucleotide microarrays. Our AZ-specific microarray chip provides a cost-effective approach for expression profiling and robust analysis of multiple samples in a rapid succession.

TI Alterations of the volatile metabolome in mouse models of Alzheimer's disease SO SCIENTIFIC REPORTS LA English DT Article ID MASS-SPECTROMETRY; TRANSGENIC MICE; CHROMATOGRAPHY/MASS SPECTROMETRY; CEREBROSPINAL-FLUID; GAS-CHROMATOGRAPHY; ORGANIC-COMPOUNDS; IN-VIVO; A-BETA; URINE; BIOMARKERS AB In the present study, we tested whether the volatile metabolome was altered by mutations of the Alzheimer's disease (AD)-implicated amyloid precursor protein gene (APP) and comprehensively examined urinary volatiles that may potentially serve as candidate biomarkers of AD. Establishing additional biomarkers in screening populations for AD will provide enhanced diagnostic specificity and will be critical in evaluating disease-modifying therapies. Having strong evidence of gross changes in the volatile metabolome of one line of APP mice, we utilized three unique mouse lines which over-express human mutations of the APP gene and their respective non-transgenic litter-mates (NTg). Head-space gas chromatography/mass spectrometry (GC/MS) of urinary volatiles uncovered several aberrant chromatographic peak responses. We later employed linear discrimination analysis and found that the GC/MS peak responses provide accurate (>84%) genotype classification of urinary samples. These initial data in animal models show that mutant APP gene expression entails a uniquely identifiable urinary odor, which if uncovered in clinical AD populations, may serve as an additional biomarker for the disease.

TI Lipoate Ester Multifunctional Lubricant Additives SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH LA English DT Article ID ALPHA-LIPOIC ACID; TRIBOLOGICAL PROPERTIES; PHYSICAL-PROPERTIES; ESTOLIDE ESTERS; VEGETABLE-OILS; FRICTION; BUTANETHIOL; STABILITY; PRESSURE AB Seven lipoate esters were synthesized by esterification of lipoic acid with different structures of alcohols in the presence of a solid acid catalyst and without solvent. The esters were obtained in good yield, characterized using H-1 NMR and GPC; and their physical properties investigated. Four of the seven lipoate esters, with good solubility in high oleic sunflower oil (HOSuO) and polyalphaolefin (PAO6) base oils, were further investigated for their lubricant additive property. Additive properties were investigated in HOSuO base oil by varying the additive concentrations in the range 0-20 (w/w %). Properties investigated include: density; kinematic and dynamic viscosity; viscosity index (VI); oxidation stability from onset and peak oxidation temperatures on a PDSC; 4-ball antiwear (AW); and 4-ball extreme pressure (EP). Neat lipoate esters displayed high oxidation stability and high VI. As additives to HOSuO base oil, lipoate esters displayed good viscosity index improver (VII), good antioxidant, good extreme pressure (EP), but poor AW properties. The VI and VII properties were attributed to the presence of low concentrations of polymeric byproducts in the ester product mixtures. This work demonstrates that lipoate esters can be developed into effective multifunctional biobased lubricant additives with excellent VII, AO and EP properties.

TI Climate Change, Carbon Dioxide, and Pest Biology: Monitor, Mitigate, Manage SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE climate change; carbon dioxide; weeds; insects; disease; management ID ELEVATED CO2; ATMOSPHERIC CO2; UNITED-STATES; INCREASED TOLERANCE; BROMUS-TECTORUM; PLANT INVASION; GLYPHOSATE; GROWTH; WEED; RESPONSES AB Rising concentrations of atmospheric carbon dioxide ([CO2]) and subsequent changes in climate, including temperature and precipitation extremes, are very likely to alter pest pressures in both managed and unmanaged plant communities. Such changes in pest pressures can be positive (migration from a region) or negative (new introductions), but are likely to be accompanied by significant economic and environmental consequences. Recent studies indicate the range of invasive weeds such as kudzu and insects such as mountain pine beetle have already expanded to more northern regions as temperatures have risen. To reduce these consequences, a better understanding of the link between CO2/climate and pest biology is needed in the context of existing and new strategies for pest management. This paper provides an overview of the probable biological links and the vulnerabilities of existing pest management (especially chemical control) and provides a preliminary synthesis of research needs that could potentially improve the ability to monitor, mitigate, and manage pest impacts.

A commercial XOS product and pectin were used as controls. Decreases in pH by 2.3, 2.4, and 2.0 units and production of short-chain fatty acids (SCFA; acetic acid, 7764.2, 6664.1, and 6387.9 mu mol/g; propionic acid, 1006.7, 1089.5, and 661.5 mu mol/g; and butyric acid, 955.5, 1252.9, and 917.7 mu mol/g) were observed in MxG XOS, commercial XOS, and pectin medium after 12 h of fermentation, respectively. Titers of Bifidobacterium spp., Lactobacillus spp., and Escherichia coli increased when fed all three substrates as monitored by qPCR. There was no significant trend for Clostridium perfringens. During fermentation, MxG XOS was statistically equivalent in performance to the commercial XOS sample as measured by culture acidification and growth of health-promoting bacteria and resulted in the highest SCFA production among the three substrates.

More than 90% of the radioactivity was distributed into the skim milk fraction for ERY, KETO, OTET, PENG, and SDMX, approximately 80% for THIA, and 13% for IVR. The distribution of drug between milk fat and skim milk fractions was significantly correlated to the drug's lipophilicity (partition coefficient, log P, or distribution coefficient, log D, which includes ionization). Data were fit with linear mixed effects models; the best fit was obtained within this data set with log D versus observed drug distribution ratios. These candidate empirical models serve for assisting to predict the distribution and concentration of these drugs in a variety of milk and milk products.

The usefulness of screening assays to identify violative flunixin levels in a variety of easily accessible ante-mortem fluids in cattle was explored. Two animals with violative flunixin liver residue and/or violative 5-hydroxy flunixin milk residues were correctly identified by a flunixin liver ELISA screen. Oral fluid did not produce anticipated flunixin concentration profiles using ELISA determination. One cow that had liver and milk violative residues, and one cow that had a milk violation at the prescribed withdrawal period were correctly identified by flunixin milk lateral flow analyses. The ratio of urinary flunixin and 5-hydroxy flunixin may be useful for predicting disruption of metabolism caused by disease or other factors potentially leading to violative liver flunixin residues.

In this study, we developed a biotin-streptavidin-amplified ELISA (BA-ELISA) using a produced monoclonal antibody for detecting pirlimycin residues in beef muscle, milk, and honey. The IC50 value of the BA-ELISA was 1.6 ng/mL for pirlimycin in buffer, and the sensitivity was improved 3 times compared to traditional ELISAs. The optimized BA-ELISA can be used to quantitate trace amounts of pirlimycin residues in beef muscle, milk, and honey. This method had limits of detection (LODs) of 4.45 mu g/kg in beef muscle, 1.65 mu g/L in milk, and 2.75 mu g/kg in honey. The average recovery of the BA-ELISA. ranged from 78 to 97%, and the coefficient of variation ranged from 5.3 to 13.5%. The developed BA-ELISA method was validated using LC-MS/MS, and the BA-ELISA can be used for routine screening analysis of pirlimycin residues.

TI Transcriptome profiling of Kentucky bluegrass (Poa pratensis L.) accessions in response to salt stress SO BMC GENOMICS LA English DT Article DE Poa pratensis; Kentucky bluegrass; Salinity stress; Transcriptome; RNA-seq; Salt tolerance ID SALINITY TOLERANCE; SCREENING TECHNIQUE; ARABIDOPSIS; PLANTS; EXPRESSION; GENE; GROWTH; RICE; CULTIVARS; WATER AB Background: Kentucky bluegrass (Poa pratensis L.) is a prominent turfgrass in the cool-season regions, but it is sensitive to salt stress. Previously, a relatively salt tolerant Kentucky bluegrass accession was identified that maintained green colour under consistent salt applications. In this study, a transcriptome study between the tolerant (PI 372742) accession and a salt susceptible (PI 368233) accession was conducted, under control and salt treatments, and in shoot and root tissues. Results: Sample replicates grouped tightly by tissue and treatment, and fewer differentially expressed transcripts were detected in the tolerant PI 372742 samples compared to the susceptible PI 368233 samples, and in root tissues compared to shoot tissues. A de novo assembly resulted in 388,764 transcripts, with 36,587 detected as differentially expressed. Approximately 75 % of transcripts had homology based annotations, with several differences in GO terms enriched between the PI 368233 and PI 372742 samples. Gene expression profiling identified salt-responsive gene families that were consistently down-regulated in PI 372742 and unlikely to contribute to salt tolerance in Kentucky bluegrass. Gene expression profiling also identified sets of transcripts relating to transcription factors, ion and water transport genes, and oxidation-reduction process genes with likely roles in salt tolerance. Conclusions: The transcript assembly represents the first such assembly in the highly polyploidy, facultative apomictic Kentucky bluegrass. The transcripts identified provide genetic information on how this plant responds to and tolerates salt stress in both shoot and root tissues, and can be used for further genetic testing and introgression.

The ability of plants to transcend the radio contaminated environment was not anticipated and is not well understood. The aim of this study was to evaluate the proteome of flax (Linum usitatissimum L.) during seed filling by plants grown for a third generation near Chernobyl. For this purpose, seeds were harvested at 2, 4, and 6 weeks after flowering and at maturity, from plants grown in either non radioactive or radio-contaminated experimental fields. Total proteins were extracted and the two-dimensional gel electrophoresis (2-DE) patterns analyzed. This approach established paired abundance profiles for 130 2-DE spots, e.g., profiles for the same spot across seed filling in non radioactive and radio contaminated experimental fields. Based on Analysis of Variance (ANOVA) followed by sequential Bonferroni correction, eight of the paired abundance profiles were discordant. Results from tandem mass spectrometry show that four 2-DE spots are discordant because they contain fragments of the cupin superfarnily-proteins. Most of the fragments were derived from the N-terminal half of native cupins. Revisiting previously published data, it was found that cupin-fragments were also involved with discordance in paired abundance profiles of second generation flax seeds. Based on these observations we present an updated working model for the growth and reproductive success of flax in a radio-contaminated Chernobyl environment. This model suggests that the increased abundance of cupin fragments or isoforms and monomers contributes to the successful growth and reproduction of flax in a radio contaminated environment.

Although APN1 has been implicated as one of the receptors for Cry1Ac in several species, its potential role in the mode of action of Cry2Ab has not been functionally determined so far. To test whether APN1 also acts as one of the receptors for Cry1Ac in Helicoverpa zea and even for Cry2Ab in this species, we conducted a gain of function analysis by heterologously expressing H. zea APN1 (HzAPN1) in the midgut and fat body cell lines of H. zea and the ovarian cell line of Spodoptera frugiperda (Sf9) and a loss of function analysis by RNAi (RNA interference) silencing of the endogenous APN1 in the three cell lines using the HzAPN1 double strand RNA (dsRNA). Heterologous expression of HzAPN1 significantly increased the susceptibility of the three cell lines to Cry1Ac, but had no effects on their susceptibility to Cry2Ab. Knocking down of the endogenous APN1 made the three cell lines resistant to Cry1Ac, but didn't change cell lines susceptibility to Cry2Ab. The findings from this study demonstrate that HzAPN1 is a functional receptor of Cry1Ac, but not Cry2Ab.

Sayed, Abu TI Real-Time Reverse Transcription PCR Assay for Detection of Senecavirus A in Swine Vesicular Diagnostic Specimens SO PLOS ONE LA English DT Article ID ONCOLYTIC PICORNAVIRUS; VALLEY-VIRUS; DISEASE; LESIONS; ASSOCIATION; PIGS AB Senecavirus A (SV-A), formerly, Seneca Valley virus (SVV), has been detected in swine with vesicular lesions and is thought to be associated with swine idiopathic vesicular disease (SIVD), a vesicular disease syndrome that lacks a defined causative agent. The clinical presentation of SIVD resembles that of other more contagious and economically devastating vesicular diseases, such as foot-and-mouth disease (FMD), swine vesicular disease (SVD), and vesicular stomatitis (VS), that typically require immediate rule out diagnostics to lift restrictions on animal quarantine, movement, and trade. This study presents the development of a sensitive, SYBR Green RT-qPCR assay suitable for detection of SV-A in diagnostic swine specimens. After testing 50 pigs with clinical signs consistent with vesicular disease, 44 (88%) were found to be positive for SV-A by RT-qPCR as compared to none from a negative cohort of 35 animals without vesicular disease, indicating that the assay is able to successfully detect the virus in an endemic population. SV-A RNA was also detectable at a low level in sera from a subset of pigs that presented with (18%) or without (6%) vesicular signs. In 2015, there has been an increase in the occurrence of SV-A in the US, and over 200 specimens submitted to our laboratory for vesicular investigation have tested positive for the virus using this method. SV-A RNA was detectable in all common types of vesicular specimens including swabs and tissue from hoof lesions, oral and snout epithelium, oral swabs, scabs, and internal organ tissues such as liver and lymph node. Genome sequencing analysis from recent virus isolates was performed to confirm target amplicon specificity and was aligned to previous isolates.

TI Dissecting the interface between apicomplexan parasite and host cell: Insights from a divergent AMA-RON2 pair SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE Apicomplexa; Toxoplasma gondii; invasion; moving junction; X-ray crystallography ID ERYTHROCYTE INVASION; MALARIA; COMPLEX; MAEBL; AMA1; IMMUNIZATION; PLASTICITY; PROTEINS; PROTECTS; ENTRY AB Plasmodium falciparum and Toxoplasma gondii are widely studied parasites in phylum Apicomplexa and the etiological agents of severe human malaria and toxoplasmosis, respectively. These intracellular pathogens have evolved a sophisticated invasion strategy that relies on delivery of proteins into the host cell, where parasite-derived rhoptry neck protein 2 (RON2) family members localize to the host outer membrane and serve as ligands for apical membrane antigen (AMA) family surface proteins displayed on the parasite. Recently, we showed that T. gondii harbors a novel AMA designated as TgAMA4 that shows extreme sequence divergence from all characterized AMA family members. Here we show that sporozoite-expressed TgAMA4 clusters in a distinct phylogenetic clade with Plasmodium merozoite apical erythrocyte-binding ligand (MAEBL) proteins and forms a high-affinity, functional complex with its coevolved partner, TgRON2(L1). High-resolution crystal structures of TgAMA4 in the apo and TgRON2(L1)-bound forms complemented with alanine scanning mutagenesis data reveal an unexpected architecture and assembly mechanism relative to previously characterized AMA-RON2 complexes. Principally, TgAMA4 lacks both a deep surface groove and a key surface loop that have been established to govern RON2 ligand binding selectivity in other AMAs. Our study reveals a previously underappreciated level of molecular diversity at the parasite-host-cell interface and offers intriguing insight into the adaptation strategies underlying sporozoite invasion. Moreover, our data offer the potential for improved design of neutralizing therapeutics targeting a broad range of AMA-RON2 pairs and apicomplexan invasive stages.

TI Migratory CD103(+) dendritic cells suppress helminth-driven type 2 immunity through constitutive expression of IL-12 SO JOURNAL OF EXPERIMENTAL MEDICINE LA English DT Article ID REGULATORY T-CELLS; LEISHMANIA-MAJOR INFECTION; SEQUENCE-BINDING-PROTEIN; SCHISTOSOMA-MANSONI; TRANSCRIPTION FACTOR; TH2 RESPONSES; NEMATODE PARASITES; CYTOKINE RESPONSES; MEDIATED-IMMUNITY; RETINOIC-ACID AB CD8 alpha(+) and CD103(+) dendritic cells (DCs) play a central role in the development of type 1 immune responses. However, their role in type 2 immunity remains unclear. We examined this issue using Batf3(-/-) mice, in which both of these DC subsets are missing. We found that Th2 cell responses, and related events such as eosinophilia, alternative macrophage activation, and immunoglobulin class switching to IgG1, were enhanced in Batf3(-/-) mice responding to helminth parasites. This had beneficial or detrimental consequences depending on the context. For example, Batf3 deficiency converted a normally chronic intestinal infection with Heligmosomoides polygyrus into an infection that was rapidly controlled. However, liver fibrosis, an IL-13-mediated pathological consequence of wound healing in chronic schistosomiasis, was exacerbated in Batf3-/- mice infected with Schistosoma mansoni. Mechanistically, steady-state production of IL-12 by migratory CD103(+) DCs, independent of signals from commensals or TLR-initiated events, was necessary and sufficient to exert the suppressive effects on Th2 response development. These findings identify a previously unrecognized role for migratory CD103(+) DCs in antagonizing type 2 immune responses.

SEM examination confirmed the fusion of the two phases to form a bilayered fiber-grafted film after the film underwent air blowing and water washing to remove the nongrafted fibers. The fiber-grafted PLA films (PfA-g-film) retain the mechanical properties of PLA. The release of AITC from the fibers was temperature dependent. At temperatures lower than 4 degrees C, the incorporated AITC remained within the fibers without losing activity; at room temperature, AITC released in a sustained manner over weeks. The release of AITC was also dependent on its initial concentration in the PLA electrospinning solution; samples with more AITC incorporated showed a higher release rate. PfA-g-films significantly inhibited the growth of Listeria innocua and Escherichia coli k12 when tested on package foods. (C) 2015 Wiley Periodicals, Inc.

TI Root biomass and soil carbon response to growing perennial grasses for bioenergy SO ENERGY SUSTAINABILITY AND SOCIETY LA English DT Article DE Bioenergy; Perennial warm-season grasses; Monocultures; Mixtures; Root biomass; Soil organic carbon; Total nitrogen ID GREENHOUSE-GAS FLUX; PANICUM-VIRGATUM L.; NITROGEN-FERTILIZATION; ORGANIC-CARBON; PLANT DIVERSITY; SWITCHGRASS; SEQUESTRATION; IMPACTS; MANAGEMENT; ACCUMULATION AB Background: Dedicated bioenergy crops such as switchgrass (Panicum virgatum L.), miscanthus [Miscanthus x giganteus (Mxg)], indiangrass [Sorghastrum nutans (L.) Nash], and big bluestem (Andropogon gerardii Vitman) can provide cellulosic feedstock for biofuel production while maintaining or improving soil and environmental quality. To better understand bioenergy crop effects on soils, we studied changes in soil properties of a Tomek silt loam under inorganic fertilization of switchgrass after 4 years and warm-season grass monocultures and mixtures after 6 years in eastern Nebraska. Methods: The first experiment had two study factors: two switchgrass harvest dates (August and November) and nitrogen (N), phosphorus (P), and potassium (K) fertilization rates. Nitrogen fertilizer levels (0, 60, and 120 kg N ha(-1)) were the main plots, while P levels (0, 22, and 44 kg P ha(-1)) were the split plots and K levels (0, 11, and 22 kg K ha(-1)) were the split-split plots. The second experiment included six bioenergy feedstocks comprised of four monocultures [switchgrass (cv. Shawnee and an experimental strain tracked as Kanlow N1), indiangrass (Chief), and miscanthus (Mxg)] and two mixtures [big bluestem (Goldmine) + indiangrass (Warrior) + switchgrass (Shawnee) and big bluestem (Bonanza) + indiangrass (Scout) + switchgrass (Shawnee)]. Soil samples were analyzed for root biomass, soil organic C (SOC), total N, bulk density, aggregate stability, and pH. Results: In the first experiment, inorganic fertilization and harvest dates had no effect on switchgrass root biomass, SOC pools, soil aggregate stability, and other properties. In the second experiment, cumulative root biomass under Chief indiangrass monoculture was lower than that under other grass monocultures and mixtures except miscanthus. These results suggest that inorganic fertilization and harvest dates do not affect soil properties in the short term, but Chief indiangrass monoculture may have lower root biomass than other grasses. Conclusions: Overall, fertilization management did not induce changes in root biomass and soil properties, but Chief indiangrass monoculture had lower cumulative root biomass compared with mixtures and switchgrass monocultures, suggesting that cultivar selection will affect root biomass accumulation. Further monitoring is needed to determine long-term changes in root biomass and soil properties under these bioenergy crop systems.

HLB was observed in Guangdong Province of China over a hundred years ago and remains endemic there. Little is known about CLas biology due to its uncultureable nature. This study began with the genome sequence analysis of CLas Strain A4 from Guangdong in the prophage region. Within the two currently known prophage types, Type 1 (SC1-like) and Type 2 (SC2-like), A4 genome contained only a Type 2 prophage, CGdP2, namely. An analysis on CLas strains collected in Guangdong showed that Type 2 prophage dominated the bacterial population (82.6%, 71/86). An extended survey covering five provinces in southern China also revealed the predominance of single prophage (Type 1 or Type 2) in the CLas population (90.4%, 169/187). CLas strains with two and no prophage types accounted for 7.2% and 2.8%, respectively. In silico analyses on CGdP2 identified a CRISPR (clustered regularly interspaced short palindromic repeats)/cas (CRISPR-associated protein genes) system, consisting of four 22 bp repeats, three 23 bp spacers and 9 predicted cas. Similar CRISPR/cas systems were detected in all 10 published CLas prophages as well as 13 CLas field strains in southern China. Both Type 1 and Type 2 prophages shared almost identical sequences in spacer 1 and 3 but not spacer 2. Considering that the function of a CRISPR/cas system was to destroy invading DNA, it was hypothesized that a pre-established CLas prophage could use its CRISPR/cas system guided by spacer 1 and/or 3 to defeat the invasion of the other phage/prophage. This hypothesis explained the predominance of single prophage type in the CLas population in southern China. This is the first report of CRISPR/cas system in the "Ca. Liberibacter" genera.

TI CLOCK gene variation is associated with incidence of type-2 diabetes and cardiovascular diseases in type-2 diabetic subjects: dietary modulation in the PREDIMED randomized trial SO CARDIOVASCULAR DIABETOLOGY LA English DT Article DE CLOCK gene; Diabetes; Cardiovascular diseases; Stroke; Mediterranean diet ID ACUTE MYOCARDIAL-INFARCTION; MAMMALIAN CIRCADIAN CLOCK; BLOOD-PRESSURE SURGE; METABOLIC SYNDROME; TRANSCRIPTION FACTOR; MEDITERRANEAN DIET; DNA METHYLATION; SLEEP DURATION; RISK-FACTORS; OBESITY AB Background: Circadian rhythms regulate key biological processes influencing metabolic pathways. Disregulation is associated with type 2 diabetes (T2D) and cardiovascular diseases (CVD). Circadian rhythms are generated by a transcriptional autoregulatory feedback loop involving core clock genes. CLOCK (circadian locomotor output cycles protein kaput), one of those core genes, is known to regulate glucose metabolism in rodent models. Cross-sectional studies in humans have reported associations between this locus and obesity, plasma glucose, hypertension and T2D prevalence, supporting its role in cardiovascular risk. However, no longitudinal study has investigated the association between CLOCK gene variation and T2D or CVD incidence. Moreover, although in a previous work we detected a gene-diet interaction between the CLOCK-rs4580704 (C > G) single nucleotide polymorphism (SNP) and monounsaturated (MUFA) intake on insulin resistance, no interventional study has analyzed gene-diet interactions on T2D or CVD outcomes. Methods: We analyzed the association between the CLOCK-rs4580704 SNP and incidence of T2D and CVD longitudinally in 7098 PREDIMED trial (ISRCTN35739639) participants after a median 4.8-year follow-up. We also examined modulation by Mediterranean diet (MedDiet) intervention (high in MUFA) on these associations. Results: We observed a significant association between the CLOCK-rs4580704 SNP and T2D incidence in n = 3671 non-T2D PREDIMED participants, with variant allele (G) carriers showing decreased incidence (dominant model) compared with CC homozygotes (HR: 0.69; 95 % CI 0.54-0.87; P = 0.002). This protection was more significant in the MedDiet intervention group (HR: 0.58; 95 % CI 0.43-0.78; P < 0.001) than in the control group (HR: 0.95; 95 % CI 0.63-1.44; P = 0.818). Moreover, we detected a statistically significant interaction (P = 0.018) between CLOCK-rs4580704 SNP and T2D status on stroke. Thus, only in T2D subjects was CLOCK-rs4580704 SNP associated with stroke risk, G-carriers having decreased risk (HR: 0.61; 95 % CI 0.40-0.94; P = 0.024 versus CC) in the multivariable-adjusted model. Conclusions: In agreement with our previous results showing a protective effect of the G-allele against hyperglycemia, we extended our findings by reporting a novel association with lower T2D incidence and also suggesting a dietary modulation. Moreover, we report for the first time an association between a CLOCK polymorphism and stroke in T2D subjects, suggesting that core clock genes may significantly contribute to increased CVD risk in T2D.

TI Identification of a Novel Small Cysteine-Rich Protein in the Fraction from the Biocontrol Fusarium oxysporum Strain CS-20 that Mitigates Fusarium Wilt Symptoms and Triggers Defense Responses in Tomato SO FRONTIERS IN PLANT SCIENCE LA English DT Article DE F oxysporum strain CS-20; Fusarium wilt of tomato; biogenic elicitor; cysteine-rich proteins; induced; resistance; biocontrol ID FILAMENTOUS PLANT-PATHOGENS; FUNGAL EFFECTOR PROTEINS; NONPATHOGENIC FUSARIUM; CLADOSPORIUM-FULVUM; TRICHODERMA-VIRENS; BIOLOGICAL-CONTROL; RESISTANCE; ELICITOR; CHITINASE; ROOTS AB The biocontrol effect of the non-pathogenic Fusarium oxysporum strain CS 20 against the tomato wilt pathogen F oxysporum f. sp. lycopersici (FOL) has been previously reported to be primarily plant-mediated. This study shows that CS-20 produces proteins, which elicit defense responses in tomato plants. Three protein containing fractions were isolated from CS-20 biomass using size exclusion chromatography. Exposure of seedling roots to one of these fractions prior to inoculation with pathogenic FOL strains significantly reduced wilt severity. This fraction initiated an ion exchange response in cultured tomato cells resulting in a reversible alteration of extracellular pH; increased tomato chitinase activity, and induced systemic resistance by enhancing PR1 expression in tomato leaves. Two other protein fractions were inactive in seedling protection. The main polypeptide (designated CS2OFP), which was specifically present in the defense inducing fraction and was not detected in inactive protein fractions, was identified. The nucleotide sequence encoding this protein was determined, and its complete amino acid sequence was deduced from direct Edman degradation (25 N-terminal amino acid residues) and DNA sequencing. The CS20EP was found to be a small basic cysteine-rich protein with a pl of 9.87 and 23.43% of hydrophobic amino acid residues. BLAST search in the NCBI database showed that the protein is new; however, it displays 48% sequence similarity with a hypothetical protein FGSG_10784 from F graminearum strain PH-1. The contribution of CS20EP to elicitation of tomato defense responses resulting in wilt mitigating is discussed.

TI Construction of high resolution genetic linkage maps to improve the soybean genome sequence assembly Glyma1.01 SO BMC GENOMICS LA English DT Article DE Soybean; Wm82.a2.v1 assembly; BARCSOYSSR_1.0 database; SoySNP50K BeadChip; euchromatic and heterochromatic regions; linkage map ID MICROSATELLITE MARKERS; WIDE ASSOCIATION; AFLP MARKERS; COPY NUMBER; REPEAT DNA; RESISTANCE; LOCI; POLYMORPHISMS; POPULATION; DISCOVERY AB Background: A landmark in soybean research, Glyma1.01, the first whole genome sequence of variety Williams 82 (Glycine max L. Merr.) was completed in 2010 and is widely used. However, because the assembly was primarily built based on the linkage maps constructed with a limited number of markers and recombinant inbred lines (RILs), the assembled sequence, especially in some genomic regions with sparse numbers of anchoring markers, needs to be improved. Molecular markers are being used by researchers in the soybean community, however, with the updating of the Glyma1.01 build based on the high-resolution linkage maps resulting from this research, the genome positions of these markers need to be mapped. Results: Two high density genetic linkage maps were constructed based on 21,478 single nucleotide polymorphism loci mapped in the Williams 82 x G. soja (Sieb. & Zucc.) PI479752 population with 1083 RILs and 11,922 loci mapped in the Essex x Williams 82 population with 922 RILs. There were 37 regions or single markers where marker order in the two populations was in agreement but was not consistent with the physical position in the Glyma1.01 build. In addition, 28 previously unanchored scaffolds were positioned. Map data were used to identify false joins in the Glyma1.01 assembly and the corresponding scaffolds were broken and reassembled to the new assembly, Wm82.a2.v1. Based upon the plots of the genetic on physical distance of the loci, the euchromatic and heterochromatic regions along each chromosome in the new assembly were delimited. Genomic positions of the commonly used markers contained in BARCSOYSSR_1.0 database and the SoySNP50K BeadChip were updated based upon the Wm82.a2.v1 assembly. Conclusions: The information will facilitate the study of recombination hot spots in the soybean genome, identification of genes or quantitative trait loci controlling yield, seed quality and resistance to biotic or abiotic stresses as well as other genetic or genomic research.

However, there is very little information on antimicrobial effect of Se against the economically important fungus Botrytis cinerea. In the present study, using sodium selenite as Se source, we investigated the effect of Se salts on spore germination and mycelial growth of the fungal pathogen in vitro and gray mold control in harvested tomato fruit. Se treatment at 24 mg/L significantly inhibited spore germination of the fungal pathogen and effectively controlled gray mold in harvested tomato fruit. Se treatment at 24 mg/L seems to induce the generation of intracellular reactive oxygen species in the fungal spores. The membrane integrity damage was observed with fluorescence microscopy following staining with propidium iodide after treatment of the spores with Se. These results suggest that Se has the potential for controlling gray mold rot of tomato fruits and might be useful in integrated control against gray mold disease of postharvest fruits and vegetables caused by a cinerea. The mechanisms by which Se decreased gray mold decay of tomato fruit may be directly related to the severe damage to the conidia plasma membrane and loss of cytoplasmic materials from the hyphae.

One outbreak with FMD virus (FDMV) serotype A and two with serotype O occurred in South Korea in 2010/2011. The causative viruses belonged to lineages that had been spreading in South East Asia, far East and East Asia since 2009 and presented a great threat to the countries in that region. Most FMDV strains infect ruminants and pigs, as it happened during the outbreaks of FMDV serotype O in South Korea. Contrastingly, the strain of serotype A affected only ruminants. Based upon these findings, the intention of the work described in the current report was to characterize and compare the infectivity, virulence and transmission of both strains under laboratory conditions in cattle and pigs, by direct inoculation and contact exposure. As expected, FMDV serotype O was highly virulent in both cattle and swine by contact exposure and direct inoculation. Surprisingly, FMDV serotype A was highly virulent in swine, but was less infectious in cattle by contact exposure to infected swine or cattle. Interestingly, similar quantities of aerosolized FMDV RNA were detected during experiments with viruses of serotypes O and A. Specific virus-host interaction of A/SKR/2010 could affect the transmission of this strain to cattle, and this may explain in part the limited spread of the serotype A epizootic.

This study used mass balances to compare wastewater treatment plant (WWTP) and upstream sources of 16 CECs to a mixed-use watershed in Minnesota, under different seasonal and hydrological conditions. Three distinct CEC groups emerged with respect to their source proportionality and instream behavior. Agricultural herbicides and daidzein inputs were primarily via upstream routes with the greatest loadings and concentrations during high flows. Trimethoprim, mecoprop, nonprescription pharmaceuticals, and personal care products entered the system via balanced/mixed pathways with peak loadings and concentrations in high flows. Carbaryl, 4-nonylphenol, and the remaining prescription pharmaceuticals entered the system via WWTP effluent with relatively stable loadings across sampling events. Mass balance analysis based on multiple sampling events and sites facilitated CEC source comparisons and may therefore prove to be a powerful tool for apportioning sources and exploring mitigation strategies.

Each diastereomer was well absorbed (73-83%), and distributed preferentially to lipophilic tissues. Feces were the major route of excretion; cumulatively accounting for 42% of dose for alpha-HBCD, 59% for beta-HBCD, and 53% for gamma-HBCD. Urine was also an important route of HBCD excretion, accounting for 13% of dose for alpha-HBCD, 30% for beta-HBCD, and 21% for gamma-HBCD. Total metabolism of HBCD diastereomers followed the rank order beta > gamma > a, and was >65% of that administered. The metabolites formed were distinct in male rats: alpha-HBCD did not debrominate or stereoisomerize, but formed two hydroxylated metabolites; beta- and gamma-HBCD were both extensively metabolized via pathways of stereoisomerization, oxidation, dehydrogenation, reductive debromination, and ring opening. beta-HBCD was biotransformed to two mercapturic acid pathway metabolites. The metabolites of beta- and gamma-HBCD were largely distinct, and could possibly be used as markers of exposure. These isomer-specific data suggest that a-HBCD would be the most dominant HBCD diastereomer in biological tissues because it was metabolized to the lowest degree and also accumulated from the stereoisomerization of the beta- and gamma- diastereomers.

TI Impacts of Human Recreation on Brown Bears (Ursus arctos): A Review and New Management Tool SO PLOS ONE LA English DT Article ID YELLOWSTONE-NATIONAL-PARK; EXPERIMENTALLY INTRODUCED TOURISM; COASTAL BRITISH-COLUMBIA; BAYESIAN BELIEF NETWORKS; GRIZZLY BEAR; BEHAVIORAL-RESPONSES; HUMAN DISTURBANCE; REPRODUCTIVE STRATEGY; POSITIVE IMPACTS; WILDLIFE AB Increased popularity of recreational activities in natural areas has led to the need to better understand their impacts on wildlife. The majority of research conducted to date has focused on behavioral effects from individual recreations, thus there is a limited understanding of the potential for population-level or cumulative effects. Brown bears (Ursus arctos) are the focus of a growing wildlife viewing industry and are found in habitats frequented by recreationists. Managers face difficult decisions in balancing recreational opportunities with habitat protection for wildlife. Here, we integrate results from empirical studies with expert knowledge to better understand the potential population-level effects of recreational activities on brown bears. We conducted a literature review and Delphi survey of brown bear experts to better understand the frequencies and types of recreations occurring in bear habitats and their potential effects, and to identify management solutions and research needs. We then developed a Bayesian network model that allows managers to estimate the potential effects of recreational management decisions in bear habitats. A higher proportion of individual brown bears in coastal habitats were exposed to recreation, including photography and bear-viewing than bears in interior habitats where camping and hiking were more common. Our results suggest that the primary mechanism by which recreation may impact brown bears is through temporal and spatial displacement with associated increases in energetic costs and declines in nutritional intake. Killings in defense of life and property were found to be minimally associated with recreation in Alaska, but are important considerations in population management. Regulating recreation to occur predictably in space and time and limiting recreation in habitats with concentrated food resources reduces impacts on food intake and may thereby, reduce impacts on reproduction and survival. Our results suggest that decisions managers make about regulating recreational activities in time and space have important consequences for bear populations. The Bayesian network model developed here provides a new tool for managers to balance demands of multiple recreational activities while supporting healthy bear populations.

SO PLOS ONE LA English DT Article ID CAUSE-SPECIFIC MORTALITY; ESTIMATING SITE OCCUPANCY; TOP PREDATORS; INTERFERENCE COMPETITION; CLIMATE-CHANGE; NORTH-AMERICA; LANDSCAPE; COYOTES; ABUNDANCE; FOXES AB Differential habitat use and intraguild competition are both thought to be important drivers of animal population sizes and distributions. Habitat associations for individual species are well-established, and interactions between particular pairs of species have been highlighted in many focal studies. However, community-wide assessments of the relative strengths of these two factors have not been conducted. We built multi-scale habitat occupancy models for five carnivore taxa of New York's Adirondack landscape and assessed the relative performance of these models against ones in which co-occurrences of potentially competing carnivore species were also incorporated. Distribution models based on habitat performed well for all species. Black bear (Ursus americanus) and fisher (Martes pennanti) distribution was similar in that occupancy of both species was negatively associated with paved roads. However, black bears were also associated with larger forest fragments and fishers with smaller forest fragments. No models with habitat features were more supported than the null habitat model for raccoons (Procyon lotor). Martens (Martes americana) were most associated with increased terrain ruggedness and elevation. Weasel (Mustela spp.) occupancy increased with the cover of deciduous forest. For most species dyads habitat-only models were more supported than those models with potential competitors incorporated. The exception to this finding was for the smallest carnivore taxa (marten and weasel) where habitat plus coyote abundance models typically performed better than habitat-only models. Assessing this carnivore community as whole, we conclude that differential habitat use is more important than species interactions in maintaining the distribution and structure of this carnivore guild.

The high genetic diversity of A. flavus populations is largely due to sexual reproduction characterized by the formation of ascospore-bearing ascocarps embedded within sclerotia. A. flavus is heterothallic and laboratory crosses between strains of the opposite mating type produce progeny showing genetic recombination. Sclerotia formed in crops are dispersed onto the soil surface at harvest and are predominantly produced by single strains of one mating type. Less commonly, sclerotia may be fertilized during co-infection of crops with sexually compatible strains. In this study, laboratory and field experiments were performed to examine sexual reproduction in single-strain and fertilized sclerotia following exposure of sclerotia to natural fungal populations in soil. Female and male roles and mitochondrial inheritance in A. flavus were also examined through reciprocal crosses between sclerotia and conidia. Single-strain sclerotia produced ascospores on soil and progeny showed biparental inheritance that included novel alleles originating from fertilization by native soil strains. Sclerotia fertilized in the laboratory and applied to soil before ascocarp formation also produced ascospores with evidence of recombination in progeny, but only known parental alleles were detected. In reciprocal crosses, sclerotia and conidia from both strains functioned as female and male, respectively, indicating A. flavus is hermaphroditic, although the degree of fertility depended upon the parental sources of sclerotia and conidia. All progeny showed maternal inheritance of mitochondria from the sclerotia. Compared to A. flavus populations in crops, soil populations would provide a higher likelihood of exposure of sclerotia to sexually compatible strains and a more diverse source of genetic material for outcrossing.

The aim of the present study was to investigate the antimicrobial resistance profiles of STEC O157 and non-O157 recovered from feces of domestic farm animals in the agricultural Culiacan Valley in Northwestern Mexico. Findings: All of the examined STEC strains showed susceptibility to five antimicrobials, ceftazidime, ceftriaxone, ciprofloxacin, nalidixic acid, and trimethoprim-sulfamethoxazole. However, resistance to the four antimicrobials, ampicillin, cephalothin, chloramphenicol, and kanamycin was commonly observed. Interestingly, non-susceptibility to cephalothin was predominant among the examined STEC strains, corresponding to 85 % (22/26) of the O157:H7 from cattle, sheep and chicken and 73 % (24/33) of the non-O157 strains from cattle and sheep. Statistical analyses revealed that resistance to ampicillin was significantly correlated to 38 % (10/26) of STEC O157:H7 strains from multiple animal sources. Another significant correlation was found between serotype, source, and antimicrobial resistance; all of the O20:H4 strains, recovered from sheep, were highly resistant to tetracycline. Multidrug resistance profiles were identified in 42 % (22/53) of the non-susceptible STEC strains with clinically-relevant serotypes O8:H9, O75:H8, O146:H21, and O157:H7. Conclusions: STEC O157 and non-O157 strains, recovered from domestic farm animals in the Culiacan Valley, exhibited resistance to classes of antimicrobials commonly used in Mexico, such as aminoglycosides, tetracyclines, cephalosporins and penicillin but were susceptible to fluoroquinolones, quinolones, and sulfonamides. These findings provide fundamental information that would aid in the surveillance of antimicrobial resistance in an important agricultural region in Northwestern Mexico.

R Beauv] is an invasive C-4 perennial grass which is listed as one of the top ten worst weeds in the world and is a major problem in the Southeast US. Five cogongrass ecotypes [Florida (FL), Hybrid (HY), Louisiana (LA), Mobile (MB), and North Alabama (NA)] collected across the Southeast and a red-tip (RI) ornamental variety were container grown for 6 months in open top chambers under ambient and elevated (ambient plus 200 ppm) atmospheric CO2. Elevated CO2 increased average dry weight (13%) which is typical for grasses. Elevated CO2 increased height growth and both nitrogen and water use efficiencies, but lowered tissue nitrogen concentration; again, these are typical plant responses to elevated CO2. The HY ecotype tended to exhibit the greatest growth (followed by LA, NA, and FL ecotypes) whiles the RI and MB ecotypes were smallest. Interactions of CO2 with ecotype generally showed that the HY, LA, FL, and/or NA ecotypes showed a positive response to CO2 while the MB and RI ecotypes did not. Cogongrass is a problematic invasive weed in the southeastern U.S. and some ecotypes may become more so as atmospheric CO2 continues to rise. C1 [Runion, G. Brett; Prior, Stephen A.; Torbert, H.

Two different multi-branched PDLA additives, a 3-arm and 4-arm star-shaped polymeric structure, were synthesized as potential heat resistance modifiers and incorporated into PLLA at 5, 10, and 20 (w/w) through melt blending. Mechanical and thermomechanical properties of these blends were compared with linear poly(l-lactide) (PLLA) as well as with blends formed by the addition of two linear PDLA analogs that had similar molecular weights to their branched counterparts. Blends with linear PDLA additives exhibited two distinct melting peaks at 170-180 degrees C and 200-250 degrees C which implied that two distinct crystalline domains were present, that of the homopolymer and that of the stereocomplex, the more stable crystalline structure formed by the co-crystallization of both d- and l-lactide enantiomers. In contrast, blends of PLLA with multi-branched PDLA formed a single broad melting peak indicative of mainly formation of the stereocomplex, behavior which was confirmed by X-ray diffraction (XRD) analysis. The heat deflection temperature determined by thermal mechanical analysis was improved for all blends compared to neat PLLA, with increases of up to180 degrees C for 20% addition of the 3-arm PLLA additive. Rheological properties of the blends, as characterized by complex viscosity (*), remained stable over a wide temperature range. (c) 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 132, 42858.

TI MaizeGDB update: new tools, data and interface for the maize model organism database SO NUCLEIC ACIDS RESEARCH LA English DT Article ID COMPARATIVE PLANT GENOMICS; ZEA-MAYS; GENETIC-RESOURCES; DATA SETS; ONTOLOGY; GRASSES; IDENTIFICATION; POPULATION; ELEMENTS; FEATURES AB MaizeGDB is a highly curated, community-oriented database and informatics service to researchers focused on the crop plant and model organism Zea mays ssp. mays. Although some form of the maize community database has existed over the last 25 years, there have only been two major releases. In 1991, the original maize genetics database MaizeDB was created. In 2003, the combined contents of MaizeDB and the sequence data from ZmDB were made accessible as a single resource named MaizeGDB. Over the next decade, MaizeGDB became more sequence driven while still maintaining traditional maize genetics datasets. This enabled the project to meet the continued growing and evolving needs of the maize research community, yet the interface and underlying infrastructure remained unchanged. In 2015, the MaizeGDB team completed a multi-year effort to update the MaizeGDB resource by reorganizing existing data, upgrading hardware and infrastructure, creating new tools, incorporating new data types (including diversity data, expression data, gene models, and metabolic pathways), and developing and deploying a modern interface. In addition to coordinating a data resource, the MaizeGDB team co-ordinates activities and provides technical support to the maize research community. MaizeGDB is accessible online at http://www.maizegdb.org.

TI Legume information system (LegumeInfo.org): a key component of a set of federated data resources for the legume family SO NUCLEIC ACIDS RESEARCH LA English DT Article ID GENOME; BIOLOGY; TOOL; CLASSIFICATION; SEQUENCE AB Legume Information System (LIS), at http://legumeinfo.org, is a genomic data portal (GDP) for the legume family. LIS provides access to genetic and genomic information for major crop and model legumes. With more than two-dozen domesticated legume species, there are numerous specialists working on particular species, and also numerous GDPs for these species. LIS has been redesigned in the last three years both to better integrate data sets across the crop and model legumes, and to better accommodate specialized GDPs that serve particular legume species. To integrate data sets, LIS provides genome and map viewers, holds synteny mappings among all sequenced legume species and provides a set of gene families to allow traversal among orthologous and paralogous sequences across the legumes. To better accommodate other specialized GDPs, LIS uses open-source GMOD components where possible, and advocates use of common data templates, formats, schemas and interfaces so that data collected by one legume research community are accessible across all legume GDPs, through similar interfaces and using common APIs. This federated model for the legumes is managed as part of the 'Legume Federation' project (accessible via http://legumefederation.org), which can be thought of as an umbrella project encompassing LIS and other legume GDPs.

TI Ensembl Genomes 2016: more genomes, more complexity SO NUCLEIC ACIDS RESEARCH LA English DT Article ID DATABASE; REVEALS; DUPLICATION; RESOURCE; PLATFORM; MAP AB Ensembl Genomes (http://www.ensemblgenomes.org) is an integrating resource for genome-scale data from non-vertebrate species, complementing the resources for vertebrate genomics developed in the context of the Ensembl project (http://www.ensembl.org). Together, the two resources provide a consistent set of programmatic and interactive interfaces to a rich range of data including reference sequence, gene models, transcriptional data, genetic variation and comparative analysis. This paper provides an update to the previous publications about the resource, with a focus on recent developments. These include the development of new analyses and views to represent polyploid genomes (of which bread wheat is the primary exemplar); and the continued up-scaling of the resource, which now includes over 23 000 bacterial genomes, 400 fungal genomes and 100 protist genomes, in addition to 55 genomes from invertebrate metazoa and 39 genomes from plants. This dramatic increase in the number of included genomes is one part of a broader effort to automate the integration of archival data (genome sequence, but also associated RNA sequence data and variant calls) within the context of reference genomes and make it available through the Ensembl user interfaces.

However, genomic tools are now becoming available so that the host-pathogen interactions can be better understood. Significant efforts are being placed on understanding the secretomes of various pathogens as secreted peptides are believed to be the best candidates for avirulence effectors. In this work, a P. triticina haustorial cDNA library was evaluated for the presence of proteins containing secretion signals. Ten predicted proteins were found in the library, of which two were expressed in haustorial fractions. Three of the secreted proteins, Pt3, Pt12 and Pt27, were used in biolistic experiments to determine whether they could induce hypersensitive cell death, which is commonly observed in incompatible rust interactions with wheat leaf rust resistance genes. When Pt3 was co-bombarded with a beta-glucoronidase (GUS)-expressing vector into wheat isolines with resistance genes Lr9 or Lr24, a significant reduction of GUS expression was observed, presumably due to hypersensitive cell death. In other co-bombardment experiments, Pt27 induced a significant reduction in GUS expression in the Lr26 isoline. These results suggest that Pt3 and Pt27 may function in avirulence against wheat leaf rust in resistant genotypes. C1 [Segovia, Vanesa; Rupp, Jessica L.

A begomovirus and its associated betasatellite were amplified and sequenced from these affected plants. Complete nucleotide sequence showed that a monopartite begomovirus named Pedilanthus leaf curl virus (PeLCV) is associated with the disease and it shared highest sequence identity (98.73%) with a clone previously reported from soybean. Characterization of the betasatellite showed that it had highest sequence identity (96-97%) with Tobacco leaf curl betasatellite (TbLCB), previously isolated from soybean. Our data shows the expansion of the host range of begomovirus-betasatellite complexes. To the best of our knowledge, this is the first occurrence of PeLCV and TbLCB on S. bispinosa.

TI Vaccination of chickens decreased Newcastle disease virus contamination in eggs SO AVIAN PATHOLOGY LA English DT Article DE vaccination; Newcastle disease virus; chickens; eggs; LaSota ID REPRODUCTIVE-TRACT; CHALLENGE; EFFICACY; VACCINES; POULTRY; STRAIN; HEN AB Newcastle disease is an important health issue of poultry causing major economic losses and inhibits trade worldwide. Vaccination is used as a control measure, but it is unknown whether vaccination will prevent virus contamination of eggs. In this study, hens were sham-vaccinated or received one or two doses of inactivated LaSota vaccine, followed three weeks later by virulent Newcastle disease virus (NDV) challenge. Eggs were collected daily and shell, albumen and yolk were subjected to virus isolation, as were oral and cloacal swabs at 2 and 4 days post-challenge (dpc). A second experiment evaluated the distribution of the virus in the reproductive tract of non-vaccinates. All vaccinated chickens survived challenge, and the levels of virus shed from cloacal swabs were decreased significantly when compared to shams. In non-vaccinated hens, virus was detected in the ovary and all segments of the oviduct. Yolk, albumen and eggshell surface from eggs laid at day 4 and 5 post-infection by sham-vaccinated hens were positive for NDV, but eggs from LaSota vaccinated hens lacked virus in internal egg components (i.e. yolk and albumen) and had reduction in the number of positive eggshell surfaces. These results indicate virulent NDV can replicate in the reproductive tract of hens and contaminate internal components of eggs and eggshell surface, but vaccination was able to prevent internal egg contamination, reducing eggshell surface contamination, and reducing shedding from digestive and respiratory tracts in virulent NDV challenged hens.

The disease is caused by Gallid herpesvirus-1 (GaHV-1) commonly known as the infectious laryngotracheitis virus. Although characterized by their potential to regain virulence, chicken embryo origin (CEO) vaccines are the most effective vaccines against laryngotracheitis as they significantly reduce the replication of challenge virus in the trachea and conjunctiva. Knowledge on the nature of protective immunity elicited by CEO vaccines is very limited. Therefore, elucidating the origin of the immune responses elicited by CEO vaccination is relevant for development of safer control strategies. In this study the transcription levels of key host immune genes (IFN-gamma, IFN-beta, IL-1 beta, IL-6, IL-8, IL-18) and viral genes (ICP4, ICP27, UL46, UL49), as well as viral genome loads in trachea were quantified at 6 and 12 hours post-challenge of CEO vaccinated and non-vaccinated chickens. Immediately after challenge a significant increase in IFN-gamma gene expression was followed by a significant reduction in viral replication. In contrast to the rapid induction of IFN-gamma, expression of the pro-inflammatory cytokines (IL-1 beta, IL-6, IL-8) and type I IFN beta was either slightly reduced or remained at basal levels. These suggest that the former cytokines may not play important roles during immediate early responses induced by ILTV challenge in either vaccinated or non-vaccinated chickens. Overall, these results suggest that the rapid expression of IFN-gamma may induce pathways of antiviral responses necessary for blocking early virus replication.

The crawler seeding mechanism combines search terms entered by users with predefined keywords that identify geospatial data services. A procedure runs daily to update map server layers and metadata, and to eliminate servers that go offline. The GSE supports Web Map Services, ArcGIS services, and websites that have geospatial data for download. We applied the GSE to search for all available geospatial services under these formats and provide search results including the spatial distribution of all obtained services. While enhancements to our GSE and to web crawler technology in general lie ahead, our work represents an important step toward realizing the potential of a publically accessible tool for discovering the global availability of geospatial data.

TI POLYCOTYLUS LATIPINNIS COPE (PLESIOSAURIA, POLYCOTYLIDAE), A NEARLY COMPLETE SKELETON FROM THE NIOBRARA FORMATION (EARLY CAMPANIAN) OF SOUTHWESTERN SOUTH DAKOTA SO JOURNAL OF VERTEBRATE PALEONTOLOGY LA English DT Article ID NORTH-AMERICAN PLESIOSAURS; TURONIAN TROPIC SHALE; REPTILIA SAUROPTERYGIA; CRANIAL ANATOMY; PART 2; UTAH; DOLICHORHYNCHOPS; PLIOSAURIDAE; VIVIPARITY; OSTEOLOGY AB A nearly complete skeleton of Polycotylus latipinnis (SDSM 23020) from the upper Niobrara Formation (early Campanian) of South Dakota (U.S.A) greatly improves information for this formerly poorly known taxon. Specimens SDSM 23020 and YPM 1125 (paratype P. latipinnis) exhibit numerous postcranial characters that distinguish Polycotylus, in particular presacral vertebral count, nature of chevron facets, unique ilia, and highly derived paddles including five epipodial ossifications and increased hyperphalangy. Greater vertebral and phalangeal counts of Polycotylus are accompanied by exceptional foreshortening; thus, the relative body and limb proportions are likely similar to less derived polycotylids, with fewer, more elongate vertebrae and phalanges. The complete skull, derived among polycotylids, has short temporal fenestrae, elongate frontals, exceptionally slender parasphenoid with prominent cultriform process, and exceptionally long extensions of the angulars and splenials within the mandibular symphysis. Cladistic analysis indicates that Polycotylus nests firmly within derived Polycotylidae as a potential sister taxon to Dolichorhynchops osborni and Trinacromerum, despite a ` primitive' presacral vertebral count. Future improvements in available data, in particular better information regarding basal polycotylids, and refinement of character selection to nullify homoplasy could significantly alter the tree structure to show distinct subgroups within Polycotylidae. North American polycotylids with elongate temporal fenestrae, elongate podials, and relatively long vertebrae are confined to occurrences of late Cenomanian and earliest Turonian age, whereas polycotylids distinctly foreshortened in these respects are restricted to post-Turonian occurrences. Ilium morphology is highly variable among polycotylids and, in addition to taxonomic utility, may be in part attributable to sexual dimorphism.

In this study we determined the recovery efficiency of vegetative E. coli O157:H7 cells that were spiked into low viscosity evaporating collection fluids during operation of a BioSampler (R) for up to 90min at room temperature. The collection fluids tested were deionized (DI) water, DI water with 0.1% (w/w) antifoam B (AFB), phosphate-buffered saline (PBS), and osmoprotectants consisting of peptone (with and without AFB) or betaine at .1% (w/w) in DI water. Using DI water, there was a rapid decline in the recovery of culturable E. coli, with only 11, 3, and 0% being recovered after 30, 60, and 90 min, respectively. Recoveries were substantially greater with use of PBS (53, 25, and 16%, respectively) but not as high as with use of the osmoprotectants or AFB. Peptone and AFB alone or together allowed for the greatest recovery of E. coli, with average values ranging from 87 to 98% at 90min. Betaine was also determined to be an effective osmoprotectant for runtimes of 30 and 60min, with respective E. coli recoveries of 101 and 77% from the impingers. The results from this study support the incorporation of peptone, AFB, and betaine in collection fluids for BioSampler runtimes from 30 to 90min. Runtimes longer than the recommend 30min with low viscosity collection fluids are sometimes necessary when the airborne concentration of a target microorganism is low and one is trying to increase the probability of detection.

A new method of polymerizing epoxidized soybean oil has been devised with the use of fluorosulfonic acid. Depending on the reaction conditions, one can get a viscous oil or a solid as the reaction product. The reaction mechanism has been studied through a systematic examination of the fluorosulfonic acid-initiated reaction of epoxidized methyl oleate and epoxidized methyl linoleate. Through C-13 NMR spectroscopy, the major species derived from fluorosulfonic acid-initiated polymerization of epoxidized soybean oil have been determined. The effects of temperature, initiator dosage, and reaction time have been studied and shown to affect the nature of polymer products obtained and the distribution of different chemical species present.

This paper explores the integration of Mori values in water and land policies governing Kaipara Harbour in New Zealand as a case study for this approach. Multijurisdictional documents were analysed for the inclusion of nine well-established Mori values that have applications to land, water and natural resource management. The results of this study identified the most and least commonly mentioned values in policy documents, and a scalar trend in which integration of Mori values increased as the geographic scale and jurisdiction of the respective governing policies decreased.

TI A Rapid Method to Determine Starch Damage in Sorghum SO INTERNATIONAL JOURNAL OF FOOD PROPERTIES LA English DT Article DE Calibration; Iodine absorption; SDmatic; Sorghum; Starch damage; Starch granule AB As a major component of cereal grains, including sorghum, starch plays an important role not only in grain development but also in post-harvest processing and end-product quality. Since milling can lead to the inadvertent disruption of starch granules, negatively affecting dough rheology, monitoring of starch damage is an important part of flour formulation. As the existing methods for quantifying starch damage are time-consuming, an alternative non-enzymatic methodology was sought. This study described the use of SDmatican instrument developed for determining starch damage in wheat flourfor assessment of sorghum flour via generation of a standard calibration. The known starch damage values were integrated to the SDmatic Ai%, and the starch damage was calculated using the following equation: Starch Damage = aAi%(2) + bAi% + c. The following variables were developed for calibrating sorghum starch damage: a = 0.168, b = -30.123, and c = 1349.648. Using this calibration developed specifically for sorghum flour increased our linear regression from initial R-2 = 0.38 to R-2 = 0.95. C1 [Wilson, J. D.; Kaufman, R. C.; Seabourn, B. W.; Galant, A.

The SMAP radiometer began acquiring routine science data on March 31, 2015 and continues to operate nominally. SMAP's radiometer-derived soil moisture product (L2_SM_P) provides soil moisture estimates posted on a 36 km fixed Earth grid using brightness temperature observations from descending (6 am) passes and ancillary data. A beta quality version of L2_SM_P was released to the public in September, 2015, with the fully validated L2_SM_P soil moisture data expected to be released in May, 2016. Additional improvements (including optimization of retrieval algorithm parameters and upscaling approaches) and methodology expansions (including increasing the number of core sites, model-based intercomparisons, and results from several intensive field campaigns) are anticipated in moving from accuracy assessment of the beta quality data to an evaluation of the fully validated L2_SM_P data product.

This paper describes a multi-scale LST-based energy balance model built using a Two-Source Energy Balance (TSEB) algorithm, which solves for the soil/substrate and canopy temperatures and flux partitioning. A regional modeling system applies the TSEB to time-differential LST measurements from geostationary satellites, providing coarse ET estimates which can be downscaled to finer spatial resolutions using data from polar orbiting satellites. This modeling system, along with strategies for fusing information from multiple satellite platforms and wavebands, has been used to generate ET maps from field to global scales. We describe applications for high spatiotemporal resolution ET retrievals in assessing impacts of human activities and climate change on water resources and agricultural production.

The models for vegetated surfaces such as wheat, grass, soybean and corn have been validated with the Soil Moisture Active Passive Validation Experiment 2012 (SMAPVEX12) data. In this paper we report progress on development of a consistent model for combined active and passive microwave remote sensing of vegetated surfaces by using the same approach to obtain backscatter and emissivity. The active model DBA/NMM3D is extended to calculate bistatic scattering for each of the three scattering mechanisms: volume, double bounce and surface scattering. Then emissivity is obtained by integration of the bistatic scattering. An advantage of this combined active and passive model is that the same physical parameters of vegetation and soil surfaces are used in both the active model and the passive model. The beta parameter that relates backscattering to emissivity is also derived for various vegetated surfaces.

This was achieved by calibrating coefficients of the regression model using SMOS soil moisture and horizontal and vertical brightness temperatures (TB), over the 2013 2014 period. Next, this model was applied to recent SMAP TB data from 31/03/201508/ 09/2015. The retrieved surface soil moisture from SMAP (referred here to as SMAP-reg) was compared to the operational SMAP L3 surface soil moisture retrieved using the single channel algorithm. Both exhibit comparable temporal dynamics with a good agreement of correlation (correlation coefficient R mostly > 0.8) between the SMAP-reg and the operational SMAP L3 surface soil moisture products.

Various soil moisture products are being developed using AMSR observations. The JAXA soil moisture along with the Single Channel Algorithm (SCA) product were evaluated using in situ observations from different geographical domains. Both the JAXA and SCA soil moisture estimates capture the overall climatological features and the overall spatial structure of the two products is similar. The JAXA soil moisture product shows a lower dynamic range in the retrieved soil moisture. The SCA performs well over low and moderately vegetated areas. This study focuses on the development of the AMSR2 soil moisture product. Validation results using in situ observations from diverse climate and land cover conditions will be presented.

Inter-comparison of L-band brightness temperature observations from different satellites (SMAP, SMOS and Aquarius) is a useful tool for radiometer calibration. Brightness temperatures observations made at the same frequency, polarization, incidence angle and coincident in time and location should be consistent with each other. SMAP brightness temperature observations were compared with SMOS observations at 40 degrees incidence angle. The observations from the two satellites were found to be consistent with each other over the entire dynamic range (both ocean and land). The RMSD between the two missions was less than 3 K. The two observations exhibit a strong linear relationship and the observed bias was less than 0.5 K for both polarizations. This bias is within the required target accuracy requirement of the SMAP radiometer (requirement of 1.3 K).

Consequently, the Soil Moisture Active Passive (SMAP) satellite applied this technique to provide global soil moisture every 2 to 3 days. To verify the performance of SMAP, the fourth and fifth campaign of SMAP Experiments (SMAPEx-4 & -5) were carried out at the beginning of the SMAP operational phase in the Murrumbidgee River catchment, southeast Australia. The airborne radar and radiometer observations together with ground sampling on soil moisture, vegetation water content, and surface roughness were collected in coincidence with SMAP overpasses. The SMAPEx-4 & -5 data sets will benefit to SMAP post-launch calibration and validation under Australian land surface conditions.

Research shows an increasing trend of baseflow over the last 60 years and may be due to this artificial drainage activity. The influence of tile drainage on streamflow has been studied using in situ measurements and hydrological models. Evapotranspiration (ET) is an important component of hydrologic cycle. However, the impact of tile drainage on ET, or on other components of the water budget, is not well documented.

These data are valuable for developing scientific products that increase our understanding of how the earth's systems are integrated. The water, energy and carbon cycle exchanges between the land and atmosphere are linked by soil moisture. NASA's Soil Moisture Active Passive (SMAP) mission provides soil moisture and freeze/thaw measurements from space and allows scientiscts to link the water energy and carbon cycles. In order for SMAP data to be best integrated into decision support systems, the mission has engaged with the stakeholder community since 2009 and has attempted to scale the utility of the data to the thematic societal impacts of the satellite product applications. The SMAP Mission, which launched on January 31, 2015, has actively grown an Early Adopter (EA) community as part of it's applications effort and worked with these EAs to demonstrate a scaled thematic impact of SMAP data product in societally relevant decision support applications. The SMAP mission provides global observations of the Earth's surface soil moisture, providing high accuracy, resolution and continuous global coverage. Through the Early Adopters Program, the SMAP Applications Team will spend the next 2 years after launch documenting and evaluating the use of SMAP science products in applications related to weather forecasting, drought, agriculture productivity, floods, human health and national security.

The current DA system relies on observations obtained from the Soil Moisture Ocean Salinity Mission (SMOS). Preliminary analysis, however, demonstrated that the accuracy of the model predictions can be improved if we perform dual assimilation. This dual assimilation system is intended to ingest Soil Moisture Active Passive (SMAP)-based soil moisture retrievals and soil moisture observations form the Advanced Scatterometer instrument (ASCAT). Currently the system has been tested using SMOS data as a proxy form SMAP. We assess the performance of this dual assimilation system framework using a global lag-correlation analysis with ranked SMOS and ASCAT soil moisture observations, and MODIS-based vegetation observations.

This paper evaluates the feasibility of using the assimilated ESA Soil Moisture Ocean Salinity (SMOS) Mission L-band passive microwave data for operational US cropland soil surface moisture monitoring. The assimilated SMOS soil moisture data are first categorized to match with the United States Department of Agriculture (USDA) National Agricultural Statistics Service (NASS) survey-based weekly soil moisture observation data, which are ordinal. The categorized assimilated SMOS soil moisture data are compared with NASS's survey-based weekly soil moisture data for consistency and robustness using visual assessment and rank correlation. Preliminary results indicate that the assimilated SMOS soil moisture data highly co-vary with NASS field observations across a large geographic area. Therefore, SMOS data have great potential for US operational cropland soil moisture monitoring. C1 [Yang, Zhengwei] USDA, Natl Agr Stat Serv, Washington, DC 20250 USA.

The data are being collected to characterize vegetation dynamics and to quantify its effects on soil moisture retrievals. A C-band radar was recently incorporated within the existing L-band radar/radiometer system called ComRAD (SMAP's ground based simulator) and an additional VHF receiver is being constructed as well. With C-band's ability to sense vegetation details and VHF's root-zone soil moisture within ComRAD's footprint, we will have an opportunity to test our ` discrete scatterer' vegetation models and parameters at various surface conditions. The purpose of this investigation is to determine optical depth and effective scattering albedo of vegetation of a given type (i.e. winter wheat) at various stages of growth that are needed to refine soil moisture retrieval algorithms for the SMAP mission.

A large fraction of this crop condition assessment is based on satellite imagery and ground data analysis. The baseline soil moisture estimates that are currently used for this analysis are based on output from the modified Palmer two-layer soil moisture model, updated to assimilate near-real time observations derived from the Soil Moisture Ocean Salinity (SMOS) satellite. The current data assimilation system is based on a 1-D Ensemble Kalman Filter approach, where the observation error is modeled as a function of vegetation density. This allows for offsetting errors in the soil moisture retrievals. The observation error is currently adjusted using Normalized Difference Vegetation Index (NDVI) climatology. In this paper we explore the possibility of utilizing microwave-based vegetation optical depth instead. C1 [Bolten, John D.] NASA, Greenbelt, MD 20771 USA.

A data fusion approach was applied to map daily LAI at 30 m spatial resolution. The LAI data from two fields were validated using insitu measurements. Cumulative LAI from two fields were compared to the 2013 grape yields. High correlations were found between yield and cumulative LAI. The within-season yield predictability was examined using daily LAI maps. Results show that the grape yields were highly correlated with the cumulative LAI after the month of June. This suggests that grape yields are predictable using remotely sensed data 2-3 months prior to harvest under normal conditions.

Our results show that R and T both change nonlinearly. The result show that the nonlinearities cancel in the ratio R/T, which appears linearly related to RWC for RWC<90%.

These error rates tend to differ between cases and controls because diagnostic and screening tests have different sensitivity and specificity. This increases the inaccuracies of classifying individuals into correct groups, giving rise to both false-positive and false-negative cases. The analysis of these noisy binary responses due to misclassification will undoubtedly reduce the statistical power of genome-wide association studies (GWAS). A threshold model that accommodates varying diagnostic errors between cases and controls was investigated. A simulation study was carried out where several binary data sets (case-control) were generated with varying effects for the most influential single nucleotide polymorphisms (SNPs) and different diagnostic error rate for cases and controls. Each simulated data set consisted of 2000 individuals. Ignoring misclassification resulted in biased estimates of true influential SNP effects and inflated estimates for true noninfluential markers. A substantial reduction in bias and increase in accuracy ranging from 12% to 32% was observed when the misclassification procedure was invoked. In fact, the majority of influential SNPs that were not identified using the noisy data were captured using the proposed method. Additionally, truly misclassified binary records were identified with high probability using the proposed method. The superiority of the proposed method was maintained across different simulation parameters (misclassification rates and odds ratios) attesting to its robustness.

Alex Sui, Ruixiu Ge, Yufeng TI Harvester-based Sensing System for Cotton Fiber Quality Mapping SO JOURNAL OF COTTON SCIENCE LA English DT Article ID COLOR MEASUREMENT PROBLEMS; IMAGE-PROCESSING SOLUTION; WIRELESS TRACKING; VARIABILITY AB Precision agriculture in cotton production attempts to maximize profitability by exploiting information on field spatial variability to optimize fiber yield and quality. For precision agriculture to be viable economically, collection of spatial variability data within a field must be automated and incorporated into normal harvesting and ginning operations. An automated prototype system that uses image processing to estimate the micronaire value of cotton fiber during harvest was designed and built. The system was based on a camera with a visible Indium Gallium Arsenide detector sensitive to a broad range of visible and near-infrared (NIR) energy. Image processing algorithms were developed to identify foreign matter in the images so that it could be excluded from the measurement of reflectance in three NIR wavebands. After the effects of foreign matter were removed, the NIR reflectance measurements had a strong relationship to standard micronaire measurements, even though the measurements were made on seed cotton, which has a high level of foreign matter compared to fiber samples. A simplified version of the system could be constructed from a similar camera with only three optical band-pass filters at 650, 1550, and 1600 nm. The prototype system developed shows promise for in-situ measurement of cotton fiber quality, specifically micronaire, and can enable creation of fiber quality maps to improve crop management and ultimately profitability.

TI Review of the genus Leptopilina (Hymenoptera, Cynipoidea, Figitidae, Eucoilinae) from the Eastern United States, including three newly described species SO JOURNAL OF HYMENOPTERA RESEARCH LA English DT Review DE Parasitoid wasps; Drosophila; Nearctic Region; geographic distribution; DNA barcoding ID DROSOPHILA; PARASITOIDS; PHYLOGENY; DIVERSITY; EVOLUTION; REVISION; TAXONOMY; GENERA AB The genus Leptopilina has historically been a poorly understood group. However, some species of Leptopilina are among the best-known model organisms for studying host-parasitoid interactions. As there is no identification system for Leptopilina in any part of the United States, we review species that were collected throughout their range in Eastern North America and those commonly used in laboratories. We provide a key for seven species, L. boulardi, L. heterotoma, L. clavipes, L. victoriae, L. decemflagella sp. n., L. maia sp. n. and L. leipsi sp. n., the last three of which are newly described here. This study is the first of its kind for Leptopilina species in North America, as our review and key were developed by examining a large number of specimens collected across broad chronological and geographic scales. This allowed us to account for the phenotypic variation within species, and helped us discover diagnostic characters. The geographic distribution and taxonomic information from this review provides a solid foundation for future research on Leptopilina.

Roots of these affected plants were hairy, deformed, and small. Molecular diagnostics failed to detect phytoplasmas in these samples, but identified Spiroplasma citri in 58 and 94% of the samples using PCR targeting the spiralin and adhesion-related protein 1 (arp1) genes, respectively. Sequence analysis confirmed the presence of S. citri, and identified a novel, putative arp gene in one carrot sample. S. citri is a phytopathogenic mollicute transmitted by leafhopper species. Beet leafhoppers (Circulifer tenellus Baker) collected in the same state of Zacatecas, Mexico, were subsequently tested for S. citri infection, and 36.5% were positive using PCR targeting the arp1 gene. Sequencing analysis confirmed the presence of S. citri in the leafhoppers. This is the first report of S. citri in carrot and C. tenellus in Mexico. Previously in the Americas, S. citri in carrot was only reported in Washington and California in the United States. The presence of S. citri in carrots and the beet leafhopper in Mexico, suggests that this pathogen could become a threat to vegetable industries in this region of Mexico, including the carrot industry.

In this work, the monitoring of water use over a basin with a predominant oak savanna (known in Spain as dehesa) was conducted for two years, 2013 and 2014, monitoring ET at both fine spatial and temporal resolution in different seasons. A global 5 km daily ET product, developed with the ALEXI model and MODIS day-night temperature difference, was used as starting point. Flux estimations with higher spatial resolutions were obtained with the associated flux disaggregation scheme, DisALEXI, using surface temperature data from the polar orbiting satellites MODIS (1 Km, daily) and Landsat 7/8 (60-120m and sharpened to 30m, 16 days) and the previously estimated coarse resolution fluxes. The results achieved supported the ability of this scheme to accurately estimate daytime-integrated energy fluxes over this system, using input data with different spatio-temporal resolution and without the need for ground observations. Daily ET series at 30 m spatial resolution, generated using STARFM fusion technique, has provided a significant improvement in spatial heterogeneity assessment of the ET series, with RMSE values of 0.56 and 0.68 mm/day for each year, representing an enhancement with respect to interpolated Landsat series. In summary, this approach was demostrated to be robust and operative to map ET at watershed scale with a suitable spatial and temporal resolution for applications over the dehesa ecosystem.

Liu, Zhenhua TI Diet- and Genetically-induced Obesity Produces Alterations in the Microbiome, Inflammation and Wnt Pathway in the Intestine of Apc(+/1638N) Mice: Comparisons and Contrasts SO JOURNAL OF CANCER LA English DT Article DE Obesity; Microbiome; Inflammation; Wnt pathway; Intestinal cancer ID COLON-CANCER; COLORECTAL-CANCER; MYD88-DEFICIENT MICE; GUT MICROBIOME; OVERWEIGHT; DISEASE; TUMORS; ALPHA; MOUSE; RISK AB Obesity is an established risk factor for colorectal cancer (CRC). Our previous study indicated that obesity increases activity of the pro-tumorigenic Wnt-signaling. Presently, we sought to further advance our understanding of the mechanisms by which obesity promotes CRC by examining associations between microbiome, inflammation and Wnt-signaling in Apc(+/1638N) mice whose obesity was induced by one of two modalities, diet-or genetically-induced obesity. Three groups were employed: Apc(+/1638N)Lepr(+/+) fed a low fat diet (10% fat), Apc(+/1638N)Lepr(+/+) fed a high fat diet (60% fat, diet-induced obesity), and Apc(+/1638N)Lepr(db/db) fed a low fat diet (genetically-induced obesity). All animals received diets for 16 weeks from 8 to 24 weeks of age. The abundance of 19 bowel cancer-associated bacterial taxa were examined by real-time PCR. The abundance of Turicibacter and Desulfovibrio decreased, but F. prausnitizii increased, in diet-induced obese mice (p < 0.05). In contrast, in genetically-induced obese mice, Bifidobacterium, A. muciniphila and E. rectale decreased, but Peptostrptococcus, and E. coli increased (p < 0.05). Both diet-and genetically-induced obesity altered the expression of genes involved in bacterial recognition (MyD88) and increased inflammation as indicated by elevated levels of cytokines (IFN gamma and TNF-alpha for genetically-induced obesity, and IL-6 for diet-induced obesity). The elevated inflammation was associated with altered expression of genes that are integral components of the Wnt-signaling cascade in a fashion indicating its activation. These findings demonstrate that the composition of the small intestinal microbiome is affected differently in diet-and genetically-induced obesity, but both are associated with elevated intestinal inflammation and alterations of the Wnt pathway towards enhancing tumorigenesis.

Malts of the two-row cultivar Harrington and the six-row cultivar Morex were incubated in maltose concentrations of 0-500 mM at 68, 73, and 78 degrees C and compared with isothermal mashing at 63 degrees C. Incubations with additions of mannitol from 0 to 500 mM at the same temperatures were used to compare with incubations containing maltose. Incubations were sampled every 30 min for 120 min, and beta-amylase activities were determined. In the absence of exogenous sugars, extracts of Harrington had higher initial beta-amylase activities than did extracts of Morex at 63, 68, and 73 degrees C but not at 78 degrees C, for which the reverse was observed. In the absence of exogenous sugars, extracts of both cultivars had the highest activities at 63 degrees C, and both exhibited maximal responses to sugar additions with 500 mM maltose (889% increase for Morex and 541% for Harrington) compared with 0 mM controls at 63 degrees C. Activities in extracts of both cultivars were significantly influenced by maltose additions starting at 50-100 mM and as early as 30 min at 63 degrees C, and these effects were pronounced at and above 200 mM maltose. The maximum % survival of beta-amylase at 120 min compared with 0 min for both cultivars occurred at 63 degrees C (85-93% for Morex and 90-91% for Harrington) when incubations were with 400 and 500 mM maltose. A comparison of beta-amylase thermostability between the cultivars was calculated as the % activity detected under the most favorable condition (0 min at 63 degrees C) and that detected under the least favorable condition (120 min at 78 degrees C). Our study showed that beta-amylase in Harrington extracts was more thermostable than that in Morex extracts (10.1 and 5.9%, respectively). beta-Amylase in both Harrington and Morex extracts showed some increases in activity and thermostability when mannitol was included in incubations. Increases were most pronounced at 63 degrees C with 500 mM mannitol. However, these effects were not as great or as consistent as seen with maltose additions to the incubations. The extent of the maximum response to both maltose and mannitol on the thermostability of beta-amylase from Morex malts was 60% greater than that of the beta-amylase from Harrington malts.

TI Maltose Effects on Barley Malt Diastatic Power Enzyme Activity and Thermostability at High Isothermal Mashing Temperatures: II. alpha-Amylase SO JOURNAL OF THE AMERICAN SOCIETY OF BREWING CHEMISTS LA English DT Article DE alpha-Amylase; Barley; Enzyme thermostability; Maltose; Mannitol; Mashing ID WORT OSMOLYTE CONCENTRATIONS; HORDEUM-VULGARE L.; BETA-AMYLASE; NITRATE REDUCTASE; FERMENTATION PERFORMANCE; SUGAR CONCENTRATIONS; QUALITY MEASUREMENTS; STARCH DEGRADATION; ACTION PATTERN; STABILIZATION AB This study was conducted to determine if maltose, the primary product of starch degradation during mashing, would affect the activity of or increase the thermostability of barley malt alpha-amylase activity at high temperatures used in mashing and temperatures above those normally used in mashing. Malts of the two-row cultivar Harrington and the six-row cultivar Morex were mashed for 2 h with maltose concentrations of 0-500 mM at temperatures from 63 to 78 degrees C. Worts were sampled every 30 min for 120 min and alpha-amylase activities determined utilizing the Megazyme Ceralpha assay. Mannitol, a polyhydric alcohol, was used for comparison. Polyhydric alcohols are known to enhance enzyme thermostability. At 63 degrees C both cultivars had relatively thermostable alpha-amylase without the addition of maltose or mannitol. However, Morex, and to a lesser extent Harrington, alpha-amylase activity was significantly elevated by high levels of either maltose or mannitol, indicating a stimulatory effect on activity in which thermostability was apparently not involved. At 73 and 78 degrees C increasing concentrations of maltose conferred considerable and highly significant (LSD analysis, P < 0.0001) thermal protection of alpha-amylase in both cultivars. For example, at 30 min of mashing at 73 degrees C, maltose concentrations of 400 and 500 mM resulted in alpha-amylase activity in Harrington of 227 and 252% and in Morex 349 and 314%, respectively, of the 0 mM maltose activity. At 60 min of mashing at 73 degrees C, concentrations of 400 and 500 mM maltose resulted in alpha-amylase activities of Harrington of 290 and 431% and Morex of 489 and 501%, respectively, of the 0 mM maltose activity. High mannitol incubations at higher temperatures such as at 73 degrees C rendered lesser alpha-amylase thermal protection than maltose; however, it was also considerable and highly significant (P < 0.0001) for both cultivars (e. g., 30 min incubation at 73 degrees C, with 400 and 500 mM maltose, respectively, alpha-amylase activities of Harrington were 163 and 174% and Morex were 188 and 260% of the 0 mM maltose activity). These data suggest that the production of maltose, as could be expected in high-gravity mashes, significantly increases the activity and thermostability of barley malt alpha-amylase.

Fungicides have been routinely used to control this disease; however, their limitations necessitate the development of alternative approaches, especially for protective culture and organic production. A disease-control strategy was developed that combines treating strawberry plants with a low dose of UV-C (low dose/short duration) followed by a specific period of darkness, which greatly increases the lethality of UV-C. A leaf disc assay was developed to evaluate the effectiveness of the UV-C treatment in controlling powdery mildew on strawberry. Irradiation for only 15 s by UV-C lamps with an output of 20.6 mu W cm(-2) followed by a 4-h dark period resulted in a significant decrease (P = 0.05) in P. aphanis as determined by the percentage of the leaf disc quadrants colonized by the fungus. An increase in irradiation exposure to 60 s followed by 4-h dark period resulted in complete control of the powdery mildew in most cases. Such treatment of strawberry plants once a week for 3 weeks resulted in more than a fourfold reduction (P = 0.01) of conidial production on adaxial leaf surfaces exposed to the UV-C irradiation, and did not affect leaf photosynthesis (P = 0.05). The UV-C treatment of plants over 15 weeks reduced the amount of diseased fruit and increased fruit yield and quality (P = 0.05).

Pythium ultimum is a component of the pathogen complex that incites apple replant disease (ARD). Previous field evaluation has demonstrated that apple rootstocks have different levels of ARD tolerance, but the underlying molecular mechanisms are unknown. Genotype responses in tissue cultured apple plants to P. ultimum infection were investigated at the biological, microscopic and molecular levels using ARD tolerant G.935 and susceptible B.9 apple rootstocks. Distinct differences in survival rate, root biomass, shoot biomass and maximum root length were observed between these two genotypes. Microscopic observations indicated contrasting dynamics in symptom development. The B.9 rootstock demonstrated an inability to limit pathogen progression, resulting in rapid progression of necrosis across the entire root system. In contrast, effective constraint of pathogen progression was shown in roots of G.935, as indicated by a limited or localized root necrosis. Apple genes, including MdCHS, MdCHIB, MdBIS and MdGLUC, which correspond to annotated functions in plant defence responses, showed differential expression profiles during infection between these two genotypes. These observations suggest that discrete molecular and biochemical processes exist in the two apple genotypes in response to P. ultimum infection.

A survey of sugar beet fields with wilt symptoms was conducted in 2007 (5 roots from each of 40 fields) and 2008 (5 roots from each of 45 fields) in Idaho. Verticillium dahliae was isolated from all root samples. From a collection of 106 V. dahliae sugar beet isolates, all were of the MAT1-2 mating type. The vegetative compatibility grouping (VCG) was evaluated for 93 of these isolates and 95, 3, 1 and 1% were VCG 4A, VCG 2B, VCG 4B and non-compatible, respectively. All the VCG 4A isolates had the same mitochondrial haplotype based on sequencing of cox3 to nad6 and cox1 to rnl loci, while the VCG 2B isolates had two haplotypes. Pathogenicity tests on sugar beet cultivar 'Monohikari' revealed that the VCG 4A isolates produced more foliar symptoms (P < 0.0001) than VCG 1, 1A, 2A, 2B, 3 and 4B isolates, but none of the VCGs consistently reduced root and foliage weight. Since V. dahliae VCG 4A isolates have also been reported as a pathogen of potato in North America, rotating sugar beet fields with potato could be a concern.

However, the exact comparison between these two material forms is not known. The objective of this research was to evaluate and compare the impacts of raw biomass chips with biochar produced from the same feedstock. Both raw biomass (pine chips; Pinus taeda) and a corresponding pine-chip biochar (slow pyrolysis; 2 h, 500 degrees C) were added to a sandy-textured Ultisol at three different rates and four incremental particle-size fractions (1-2, 0.5-1, 0.2-0.5, and <0.2 mm). Results demonstrated that the immediate impact on hydraulic conductivity (K-sat) of the amended soil was influenced by application rate and particle size, with remarkable similarity between the two amendments. All additions significantly reduced both the soil bulk density and K-sat (P<0.05). These alterations in the hydraulic properties were postulated to be due to alterations in soil particle packing (i.e., tortuosity). Alterations in pore geometry, with blocking of larger macropores by the amendment, could explain this behavior, and this was supported by the similar behavior between raw feedstock and biochar of equal particle sizes. Thus, the immediate alterations in the hydraulic properties of an amended soil were primarily a function of the particle size of the material, regardless of whether or not the raw feedstock had been converted to biochar. With decreasing particle size, both additions increased water-holding capacity at saturation. This suggests that small-particle-size additions to a sandy-textured soil would reduce infiltration rates and net water gained per precipitation event due to the reduced soil moisture potential gradient and K-sat. However, the effects are a function of the amendment particle size distribution and the original soil texture. C1 [Spokas, K.

Malus sieversii, an apple species native to Kazakhstan and a progenitor of the modern domesticated apple (Malus x domestica) is considered a reservoir of genetic diversity for many economically important traits. Earlier research has demonstrated that some genotypes of M. sieversii are highly resistant to postharvest pathogens such as Penicillium expansum. One such genotype, PI613981, was crossed with 'Royal Gala' to create a mapping population, GMAL4593. In addition to P. expansum resistance, this population also segregates for fire blight and apple scab resistance, water use efficiency, and coddling moth and oblique banded leaf roller resistance. A genetic framework map based on 171 individuals of this population has been created and the harvested fruit has been phenotyped for resistance to P expansum. Preliminary QTLs for blue mold resistance have been identified on LG4 and LG 10. The identification of such markers is a first step in providing new markers for use in marker-assisted-breeding. Confirmation of the QTLs is currently in progress using maps with a higher density of markers along with a more comprehensive data set for resistance (more individuals and more years). Transcriptomic analyses have also been conducted to identify genes specifically associated with a resistance response and that may represent gene-specific markers.

EXPANSUM; RESISTANCE AB Penicillium expansum is the causal agent of blue mould of pome fruits and is responsible for important economical losses during postharvest handling in all producing countries. Although control of this pathogen can be achieved by using chemical fungicides, the appearance of resistant strains and increasing public concern about the use of chemicals in food products have motivated the study of host pathogen interactions. To develop a better understanding of disease resistance mechanisms in apples, a comprehensive transcriptional analysis of apple gene expression in response to a compatible (P. expansum) and non-host (Penicillium digitatum) pathogen was conducted using an apple microarray of approximately 40,000 probes. The obtained data provide further evidence that apples inoculated with P. expansum exhibit significant upregulation of defense-related genes and genes involved in detoxification of reactive oxygen species. In contrast, apples inoculated with P. digitatum, a non-host pathogen, exhibited upregulation of genes involved in phenylpropanoid metabolism. To confirm the accuracy of the expression profiles obtained with the microarray, reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) was conducted for four genes involved in the phenylpropanoid pathway (PAL1, PAL2, COMT2 and POX64). Expression data were obtained for different time points after inoculation and fruit maturity stages. The highest expression level of the phenylpropanoid genes was detected 48 h after inoculation with P. expansum in both immature and mature apples. Collectively, the results of the present study support the hypothesis that apples exhibit a more complex and diverse defense response to the compatible pathogen than to the non-host pathogen. P. expansum, however, is able to overcome these defenses and successfully infect apples. C1 [Vilanova, L.; Torres, R.; Usall, J.; Teixido, N.] IRTA, XaRTA Postharvest, Lleida, Catalonia, Spain.

Infections arise from colonization of the gastrointestinal (GI) tract, where C. albicans is part of the normal microflora. Reducing colonization in at-risk patients using antifungal drugs prevents C. albicans- associated mortalities. C. albicans provides a clinically relevant system for studying the relationship between diet and the microbiota as it relates to commensalism and pathogenicity. As a first step toward a dietary intervention to reduce C. albicans GI colonization, we investigated the impact of dietary lipids on murine colonization by C. albicans. Coconut oil and its constituent fatty acids have antifungal activity in vitro; we hypothesized that dietary coconut oil would reduce GI colonization by C. albicans. Colonization was lower in mice fed a coconut oil-rich diet than in mice fed diets rich in beef tallow or soybean oil. Switching beef tallow-fed mice to a coconut oil diet reduced preexisting colonization. Coconut oil reduced colonization even when the diet also contained beef tallow. Dietary coconut oil also altered the metabolic program of colonizing C. albicans cells. Long-chain fatty acids were less abundant in the cecal contents of coconut oil-fed mice than in the cecal contents of beef tallow-fed mice; the expression of genes involved in fatty acid utilization was lower in C. albicans from coconut oil-fed mice than in C. albicans from beef tallow-fed mice. Extrapolating to humans, these findings suggest that coconut oil could become the first dietary intervention to reduce C. albicans GI colonization. IMPORTANCE Candida albicans, the most common human fungal pathogen, can cause infections with a mortality rate of similar to 40%. C. albicans is part of the normal gut flora, but when a patient's immune system is compromised, it can leave the gut and cause infections. By reducing the amount of C. albicans in the gut of susceptible patients, infections (and the resulting fatalities) can be prevented. Currently, this is done using antimicrobial drugs; to "preserve" drugs for treating infections, we looked for a dietary change to reduce the amount of C. albicans in the gut. Using a mouse model, we showed that adding coconut oil to the diet could become the first drug-free way to reduce C. albicans in the gut. More broadly, this model lets us study the interactions between our diet and the microbes in our body and the reasons why some of those microbes, under certain conditions, cause disease.

Here, we report the development of four new monoclonal antibodies (MAbs) against Stx1e, a novel subtype of Stx1 that was produced by an Enterobacter cloacae strain and had limited reactivity with existing anti-Stx1 antibodies. Western blot analysis indicates that these MAbs were Stx1 specific, bound to the A subunit, and had distinct preferences for subtypes of Stx1. Of the four MAbs, Stx1e-2 was capable of partially neutralizing cytotoxicities derived from Stx1e in Vero cells. Enzyme-linked immunosorbent assays assembled with these high-affinity MAbs detected Stx1e at concentrations as low as 4.8 pg/ml in phosphate-buffered saline and 53.6 pg/ml in spiked human serum samples and were also capable of distinguishing Stx1e-producing strains in enriched cultures. These assays may therefore have clinical value in diagnosing Stx1e-producing bacterial infection. Additionally, characteristics of Stx1e, such as the origin of stx1e genes, conditions for toxin expression, receptor binding, and cytotoxicity, were investigated with the new antibodies developed in this study. This information should be useful for further understanding the clinical significance and prevalence of Stx1e-harboring E. cloacae and other organisms. IMPORTANCE Stxs are among the most clinically important virulence factors of Shigella and enterohemorrhagic Escherichia coli. There are many varieties of Stx, and although Stx1a and Stx2a are the most common and widely distributed types of Stx, new variants of Stx are continually emerging. These new variants of Stx can be challenging to detect, since most Stx detection kits are optimized for the detection of Stx1a and Stx2a. Stx1e, recently discovered in an atypical host (Enterobacter cloacae), is undetectable by many Stx assays. To formulate new assays for the detection of Stx1e, we generated four new MAbs that recognize this Stx subtype. Using these antibodies, we generated an assay capable of detecting Stx1e at low picogram-permilliliter concentrations. This assay is also compatible with a human serum matrix, suggesting that it may have utility for the clinical detection and diagnosis of Stx1eassociated infections.

TI FUSION OF SPECTRAL AND ELECTROCHEMICAL SENSOR DATA FOR ESTIMATING SOIL MACRONUTRIENTS SO TRANSACTIONS OF THE ASABE LA English DT Article DE Ion-selective electrode; Phosphorus; Potassium; Precision agriculture; Reflectance; Soil sensing ID INFRARED REFLECTANCE SPECTROSCOPY; PHYSICAL-PROPERTIES; SYSTEM; PHOSPHORUS; NITRATE; DELINEATION; ELECTRODES; MANAGEMENT; ZONES; FIELD AB Rapid and efficient quantification of plant-available soil phosphorus (P) and potassium (K) is needed to support variable-rate fertilization strategies. Two methods that have been used for estimating these soil macronutrients are diffuse reflectance spectroscopy in visible and near-infrared (VNIR) wavelength ranges and electrochemical sensing using an automated ion-selective electrode (ISE) system. The goal of this research was to compare P and K estimates with VNIR spectroscopy, ISE analysis, and a data fusion approach that combined the two methods. Diffuse reflectance spectra of air-dried, sieved samples were obtained in the laboratory. Estimates of P and K based on ISE measurements and standard laboratory analysis methods were available for the same samples from a previous study. Calibrations relating spectra to P, K, and other soil properties determined by standard laboratory methods were developed using partial least squares regression with leave-one-out cross-validation. Although good models (R-2 = 0.83 to 0.92, residual prediction deviation (RPD) = 2.45 to 3.60) for soil texture fractions, organic matter, and CEC were obtained using the spectral data, models for pH, P, and K were not good (R-2 <= 0.7, RPD <= 1.81). Models for P and K based on ISE data fit better (R-2 >= 0.88, RPD >= 2.96), but both P and K were systematically underestimated by over 40% due to a large slope bias in both models. Including both spectral and ISE information in P and K calibrations improved model fits (R-2 >= 0.90, RPD >= 3.19) and reduced the systematic slope bias underestimation to less than 10%, resulting in a considerable improvement in accuracy over ISE data alone. In P and K models including ISE data and spectrally estimated soil properties, significant variables included texture and cation exchange capacity, suggesting that these soil properties might affect the relationship of ISE-measured P and K to values determined by standard laboratory methods. These improved results obtained with a data fusion approach using laboratory-collected data are promising and warrant further investigation with additional datasets. C1 [La, W.

Embankment failures are most commonly caused by overtopping or internal erosion. This study aims to develop a practical numerical model for simulating the overtopping and embankment breach process. To achieve that goal, the key physical-empirical breach mechanism of earth embankments is adopted and implemented in the CCHE2D flow and sediment transport model. A special function describing the shape of the breach channel profile is introduced, which significantly simplifies the breach modeling work. The developed model is validated using physical data. The simulated breach hydrograph, headcut migration, and breach embankment profiles agree well with the observed data. Because this is a two-dimensional model, it makes possible the simulation of breaches in more complex conditions as well as multiple embankment breaches at the same time, which significantly broadens the applicability of the model.

TI IMPACT OF DIETARY CARBOHYDRATE AND PROTEIN SOURCE AND CONTENT ON SWINE MANURE FOAMING PROPERTIES SO Transactions of the ASABE LA English DT Article DE Anaerobic digestion; Dietary carbohydrate; Dietary protein; Foaming; Methane production; Swine manure ID MICROBIAL COMMUNITY; ANAEROBIC-DIGESTION; AMMONIA EMISSION; GROWING PIGS; MYCOLATA; SLURRY AB Diet ingredients are thought to contribute to foaming problems associated with swine manure stored in deep-pit systems. Two experiments explored the impact of protein and carbohydrate sources and levels in swine diets on the physicochemical properties, methane production potential, and foaming potential of swine manure. The first experiment was specific to protein and evaluated the impact of dietary protein level and source on manure properties, while the second experiment focused on evaluating the impact of different dietary carbohydrate sources on manure foaming properties. Manure from the animals was tested for total and volatile solids, methane production rate and biochemical methane potential, surface tension, foaming capacity and stability, and microbial community structure. No single diet yielded manure with all of the anticipated qualities associated with foaming manure. However, manure collected from pigs fed diets containing soy hulls and distillers dried grains with solubles (DDGS) exhibited higher methane production rates (0.95 +/- 0.20 and 0.96 +/- 0.20 L CH4 kg(-1) VS, respectively) and biochemical methane potential (322 +/- 25 and 269 +/- 22 mL CH4 g(-1) VS, respectively) when compared to manure obtained from pigs fed the other diets. Additionally, the results showed that both protein level and source exhibited greater influence over the microbial community than carbohydrate source, with manipulations in the protein diet leading to positive correlations with specific microbial community and higher methane production rates, foaming capacity, and foam stability. In this study, these parameters appeared to be tied to higher levels of corn, or corn protein, in the diet. Although some of the microbial community was explained by diet, this study also demonstrated that factors other than diet have significant influence on microbial community. C1 [Van Weelden, M.

TI DEMONSTRATION TESTS OF INFRARED PEELING SYSTEM WITH ELECTRICAL EMITTERS FOR TOMATOES SO Transactions of the ASABE LA English DT Article DE Dry-peeling; Energy management; Infrared heating; Peelability; Steam peeling; Tomato peeling ID PROCESSING TOMATOES; STEAM; PEELABILITY; PEACHES; FRUITS; YIELD; LYE AB Infrared (IR) dry-peeling is an emerging technology that could avoid the drawbacks of steam and lye peeling of tomatoes. The objectives of this research were to evaluate the performance of an IR peeling system at two tomato processing plants in California and to compare product quality, peelability, and energy consumption of IR and steam peeling. The system was continuously operated using tomatoes of different sizes and cultivars. High percentages (62% to 85%) of fully peeled tomatoes were obtained and varied depending on tomato cultivar and seasonality. IR dry-peeled tomatoes had a firmer texture than steam and lye peeled tomatoes. IR peeling achieved a peeling loss in the range of 17% to 42%, which was lower than typical loss in the industry. Small tomatoes had higher loss than large tomatoes in the late season. Thermal energy consumption of the proposed technology in full-scale production (10 ton h(-1)) is predicted to be 117.0 and 137.3 MJ ton(-1) for indoor and outdoor operation, respectively. The estimated energy savings of IR dry-peeling should be 22% and 28% compared to lye and steam peeling, respectively. The demonstration results showed that the IR dry-peeling technology could be a viable alternative to lye and steam peeling.

TI APPROACHES FOR GEOSPATIAL PROCESSING OF FIELD-BASED HIGH-THROUGHPUT PLANT PHENOMICS DATA FROM GROUND VEHICLE PLATFORMS SO Transactions of the ASABE LA English DT Article DE Field-based high-throughput plant phenotyping; Georeferencing; Ground vehicles AB Understanding the genetic basis of complex plant traits requires connecting genotype to phenotype information, known as the "G2P question." In the last three decades, genotyping methods have become highly developed. Much less innovation has occurred for measuring plant traits (phenotyping), particularly under field conditions. This imbalance has stimulated research to develop methods for field-based high-throughput plant phenotyping (HTPP). Sensors installed on ground vehicles can provide a huge amount of potentially transformative phenotypic measurements, orders of magnitude larger than provided by traditional phenotyping practice, but their utility requires accurate mapping. Using geospatial processing techniques, sensor data must be consistently matched to their corresponding field plots to establish links between breeding lines and measured phenotypes. This article examines problems and solutions for georeferencing sensor measurements from ground vehicle platforms for field-based HTPP. Using three case studies, the importance of vehicle heading for sensor positioning is examined. Three corresponding approaches for georeferencing are introduced based on different methods to estimate vehicle heading. For two of the cases, approaches to develop a field map of plot areas are addressed, where the issue is to ensure that sensor positions are correctly assigned to plots. Two solutions are proposed. One uses a geographic information system to design a field map before planting, while the other adopts an algorithm that calculates plot boundaries from the georeferenced sensor measurements. An advantage of the latter approach is the accommodation of irregular planting patterns. Using the algorithm to calculate the plot boundaries of a winter wheat field in Kansas, 98.4% of the calculated plot centers were within 0.4 m of the surveyed plot centers, and all of the calculated plot centers were within 0.6 m of the surveyed plot centers. While multiple options and software tools are available for geospatial processing of field-based HTPP data, they share common problems with sensor positioning and plot delineation. The options and tools presented in this study are distinguished by their practicality, accessibility, and ability to rapidly map phenotypic data. C1 [Wang, X.; Poland, J.

TI EVALUATION OF A LASER SCANNING SENSOR IN DETECTION OF COMPLEX-SHAPED TARGETS FOR VARIABLE-RATE SPRAYER DEVELOPMENT SO Transactions of the ASABE LA English DT Article DE Automation; Canopy measurement; Laser sensor; Nursery; Orchard; Precision sprayer ID TREE CANOPY CHARACTERISTICS; AIR-ASSISTED SPRAYER; DEPOSITION; ORCHARDS; VOLUME AB Sensors that can accurately measure canopy structures are prerequisites for development of advanced variable-rate sprayers. A 270 degrees radial range laser sensor was evaluated for its accuracy in measuring the dimensions of target surfaces with complex shapes and sizes. An algorithm for data acquisition and three-dimensional (3-D) canopy image construction were designed and processed with an embedded computer. Test targets included three beach balls at three heights, a rectangular box, a cylinder, two artificial trees, and three field-grown ornamental trees. Other variables included 2, 3, 4, and 5 m detection distances and sensor travel speeds of 3.2, 4.8, 6.4, and 8.0 km h(-1). The laser sensor measurements of the test targets were statistically similar with the actual measurements. The average root mean square error (RMSE) and coefficient of variation (CV) varied slightly with detection distance and travel speed. Among all the dimension measurements in the ranges of 0.58 to 2.54 m in the X direction, 0.58 to 2.54 m in the Y direction, and 0.58 to 2.94 m in the Z direction, the highest average RMSE of 68 mm occurred in the Z direction and the highest average CV of 8.6% occurred in the Y direction. Similarity of paired images from the laser sensor and a camera was greater than 0.85 for all targets. These tests confirmed the capability of the laser sensor and the algorithm to accurately measure complex-shaped targets, offering potential for integration of the sensor and algorithm into sprayers that would make real-time adjustment of spray outputs to match plant structures and travel speeds.

TI EVALUATION OF THE WAKE OF AN AGRICULTURAL GROUND SPRAYER WITH THE WIND FROM ANY DIRECTION SO Transactions of the ASABE LA English DT Article DE AGDISP; Ground sprayer; Subscale model; Tractor wake; Wind tunnel ID TURBULENCE CLOSURE; BOOM AB Additional wind tunnel measurements of wind direction effects on the wake of a subscale tractor, tank, and spray boom model (representing a typical ground sprayer and henceforth referred to as a "spray rig") are presented to demonstrate the behavior of the dominant air motions responding to the presence of a spray rig. The approach measures the velocity and turbulence levels (in three directions) with the wind blowing from five angles (from directly toward the front of the tractor to directly toward the back of the tractor in 45 degrees increments). The results quantify the effect on wind direction and turbulence level by the presence of the spray rig model. The goal of this effort is to combine and analyze these measurements to describe the full-scale wake of a specific tractor/tank/spray boom combination. In this way, the wake model will augment local atmospheric and surface effects to better predict the behavior of material released from nozzles on a spray boom during actual ground sprayer operation.

TI AERIALLY RELEASED SPRAY PENETRATION IN A TALL CONIFEROUS FOREST CANOPY SO Transactions of the ASABE LA English DT Article DE Aerial spraying; Biopesticide; Canopy penetration; Hemlock woolly adelgid; Insecticide; Pesticide spraying ID TREE CANOPY; DEPOSITION; INTERCEPTION; RETENTION; AGDISP; MODEL; DISPERSION; FOLIAR AB An aerial spray deposition project was designed to evaluate aerial application to an eastern hemlock (Tsuga canadensis) canopy to combat hemlock woolly adelgid (Adelges tsugae). This adelgid, residing in the forest canopy at the nodes of branchlets, offers a difficult target. The study collected 1840 deposition samples on live and artificial collectors (not including auxiliary studies) positioned to evaluate canopy penetration of spray applied from above the canopy by helicopter. The results of the study show that canopy penetration is achieved with 3% to 8% of applied material (corrected for foliar area) deposited on the lowest samplers and 6% to 12% deposited on samplers positioned in hard-to-reach locations in the mid-canopy. The study also suggests that it might not be necessary to apply as fine a droplet distribution (release D-V0.5 values of 87 and 108 mu m are used in most of the trials described here) as originally thought to achieve coverage in this deep canopy. A second article will compare these data to existing models. C1 [Thistle, H. W.; Reardon, R. C.; Felton, K. D.; Onken, B. P.] US Forest Serv, USDA, 180 Canfield St, Morgantown, WV 26505 USA.

TI CHARACTERIZATION AND PLACEMENT OF WETLANDS FOR INTEGRATED CONSERVATION PRACTICE PLANNING SO Transactions of the ASABE LA English DT Article DE GIS; Precision conservation; Topographic analysis; Watershed modeling; Wetland ID CONSTRUCTED WETLANDS; WATER; DENITRIFICATION; ECOSYSTEMS; RETENTION; FRAMEWORK; NITROGEN; REMOVAL AB Constructed wetlands have been recognized as an efficient and cost-effective conservation practice to protect water quality through reducing the transport of sediments and nutrients from upstream croplands to downstream water bodies. The challenge resides in targeting the strategic location of wetlands within agricultural watersheds to maximize the reduction in nutrient loads while minimizing their impact on crop production. Furthermore, agricultural watersheds involve complex interrelated processes requiring a systems approach to evaluate the inherent relationships between wetlands and multiple sediment/nutrient sources (sheet, rill, ephemeral gully, channels) and other conservation practices (filter strips). This study describes new capabilities of the USDA's Annualized Agricultural Non-Point Source pollutant loading model, AnnAGNPS. A developed AnnAGNPS GIS-based wetland component, AgWet, is introduced to identify potential sites and characterize individual artificial or natural wetlands at a watershed scale. AgWet provides a simplified, semi-automated, and spatially distributed approach to quantitatively evaluate wetlands as potential conservation management alternatives. AgWet is integrated with other AnnAGNPS components providing seamless capabilities of estimating the potential sediment/nutrient reduction of individual wetlands. This technology provides conservationists the capability for improved management of watershed systems and support for nutrient credit trading programs. C1 [Momm, H.

TI VISIBLE AND NEAR-INFRARED INSTRUMENTS FOR DETECTION AND QUANTIFICATION OF INDIVIDUAL SPROUTED WHEAT KERNELS SO Transactions of the ASABE LA English DT Article DE Falling number; Near-infrared; Sorting; Sprouting damage; Wheat ID ALPHA-AMYLASE; PROTEIN-CONTENT; BULK WHEAT; PREHARVEST; RESISTANCE; SPECTROSCOPY; REFLECTANCE; GERMINATION; QUALITY; GRAINS AB Pre-harvest sprouting of wheat kernels within the grain head presents serious problems as it can greatly affect end-use quality. Functional properties of wheat flour made from sprouted wheat result in poor dough and bread-making quality. This research examined the ability of two instruments, a single-kernel near-infrared (SKNIR) spectroscopy instrument and a silicon light-emitting diode (SiLED) sorter, to estimate the level of sprouting in single kernels of wheat in order to provide breeders with a quick method to evaluate sprouting resistance. The SKNIR uses near-infrared reflectance (NIR) spectra spanning 990 to 1700 nm, while the SiLED uses a silicon sensor to measure visible reflected light obtained from a kernel using several LEDs at discrete wavelengths. Multiple varieties of hard white (HW) and soft red winter (SRW) wheat were conditioned to nine sprouting levels, S1 (untreated) to S9 (highly sprouted), using a multi-step soaking protocol, with falling number (FN) determined from subsamples of each sprouting level. Partial least squares model predictions of FN based on single-kernel NIR spectra yielded R-2 values of 0.59 to 0.72. This improved when the spectral averages from 30 kernels were used to predict FN, resulting in R-2 values of 0.78 to 0.95. Sprouting that was separated into three levels (sound, intermediate, and severely sprouted) could be classified reasonably well using the NIR instrument. The SiLED sorter was used to sort samples at each of the nine sprouting levels into two classes (sound and unsound kernels), with sound kernels re-sorted twice. Sprouted kernels were then visually identified from the three sound streams and quantified by weight. Linear models developed based on these weights were used to predict FN and sprouted kernels. Models were marginal in most cases, with R-2 values ranging from 0.59 to 0.87. Overall, both instruments can identify samples with minimal or no sprouting and those with more severe sprouting; kernels with intermediate levels of sprouting were difficult to quantify.

Geospatial data of historical climate, land use, soil, and management were coupled with a weather generator, the crop models SPUDSIM and MAIZSIM, and both spatially and temporally downscaled mid-century climate change data from HadCM3. Simulations were conducted at a sub-county level to investigate potential potato yield and corn silage production in response to (1) current climate and agricultural land use, (2) current climate and potential land use, and (3) two future climate scenarios and potential land use. Water management with rainfed or irrigated production was assessed for all scenarios. Potato growth was highly concentrated in northern states, while corn was distributed throughout the NESR. Average estimates for potato yield and corn silage across the region under current climate and land use were 27 and 33 Mg ha(-1), respectively. The impacts of climate change were similar for the two future climate scenarios; potato yields declined by an average of 50%, and corn silage declined by 19%. To reclaim 100% of current production capacity under the future climate scenarios, roughly double the land area would be required for potato and a 23% increase in land area would be required for corn. Providing irrigation throughout the region would largely mitigate the negative impacts of climate for both crops, assuming this was an economically viable adaptation strategy. Response to irrigation was negatively correlated with latitude; however, this effect was minimized for potato in southern states where irrigation is currently in practice. These results provide quantitative data for use in assessments related to regional production capacity as influenced by land availability, climate, and crop characteristics. C1 [Resop, J.

TI COTTON YIELD ESTIMATION USING VERY HIGH-RESOLUTION DIGITAL IMAGES ACQUIRED WITH A LOW-COST SMALL UNMANNED AERIAL VEHICLE SO Transactions of the ASABE LA English DT Article DE Cotton; Digital image; Unmanned aerial vehicle; Yield estimation ID CROP SURFACE MODELS; BIOMASS; BARLEY AB Yield estimation is a critical task in crop management. Traditional methods are costly, time-consuming, and difficult to expand to a relatively large field. Remote sensing can provide quick coverage over a field at any scale. Satellite remote sensing is used for large-scale earth observation. Remote sensing with manned airplanes at relatively high altitudes (>500 m) has difficulty achieving the spatial resolution required for field-scale precision farming. Ground-based systems are typically used for point measurements and are restricted to field conditions. Unmanned aerial vehicles (UAVs) provide a unique platform for high-resolution remote sensing, and UAV-based remote sensing systems can be used to estimate crop yield in a cost-effective manner. The objective of this study was to develop and evaluate new methods for estimation of cotton yield for precision cotton farming. Experimental plots were laid out in a cotton field near Stoneville, Mississippi, in 2014. Nitrogen fertilizer was applied to the plots at five different rates to generate cotton yield variation. Two methods were employed to estimate cotton yield using very high-resolution digital images (2.7 cm pixel(-1)) acquired from an inexpensive small multirotor UAV: (1) using three-dimensional point cloud data derived from multiple digital images of the cotton field to estimate cotton plant height and hence estimate yield, and (2) segmenting cotton boll signatures from the background of the digital images of the defoliated cotton field just prior to harvest and then estimating yield with the estimated cotton plot unit coverage. The results indicated that low-altitude remote sensing with an inexpensive small UAV can be used to estimate cotton yield accurately through estimation of plant height (R-2 = 0.43, compared with R-2 = 0.42 for yield estimation through manually measured plant height). The results further indicated that the method can offer reliable cotton yield estimation through estimation of cotton boll coverage in each plot with Laplacian image processing while considering a few plots with poor light condition as outliers (R-2 = 0.83). This study could benefit yield estimation of cotton, with similar methods used for other crops, in agricultural research and crop production. C1 [Huang, Y.; Sui, R.; Thomson, S.

TI INTRA-STORM TEMPORAL PATTERNS OF RAINFALL IN CHINA USING HUFF CURVES SO Transactions of the ASABE LA English DT Article DE Duration; Erosive; Hyetograph; Intensity; Precipitation; Rainfall; Storm ID PRECIPITATION; HYETOGRAPHS; RUNOFF; INFILTRATION; SIMULATION; EROSION; EVENTS AB Intra-storm temporal distributions of precipitation are important for infiltration, runoff, and erosion process understanding and models. A convenient and established method for characterizing precipitation hyetographs is the use of non-dimensional Huff curves. In this study, 11,801 erosive rainfall events with 1 min resolution data collected over 30 to 40 years from 18 weather stations located across the central and eastern parts of China were analyzed to produce Huff curves. Each event was classified according to the quartile period within the event that contained the greatest fraction of rainfall. The results showed that 38.3% of events had the maximum rainfall amounts in the first quartile, followed by the second (26.8%), third (22.4%), and fourth (12.5%) quartiles. Quartile I and II events were generally characteristic of shorter duration and heavier intensity events. Quartile I events averaged 23% shorter durations than quartile IV events, whereas the mean intensity (I-avg), mean maximum 30 min intensity (I-30), and mean rainfall erosivity index (EI30) were 1.71, 1.22, and 1.23 times greater, respectively, than those for quartile IV and were significant at a 5% level based on two-sample t-tests. The proportion of quartile I events was less for events of longer duration, whereas the proportions of quartile III and IV events were greater. Two-sample Kolmogorov-Smirnov tests suggested that regional Huff curves can be derived for the central and eastern parts of China. Regional Huff curves developed in this study exhibited dissimilarities in terms of the percentages of storms for different quartiles and the shapes of the curves compared to those reported for Illinois, peninsular Malaysia, and Santa Catarina in Brazil.

TI EFFECTS OF CHEMICAL AMENDMENTS TO SWINE MANURE ON RUNOFF QUALITY SO Transactions of the ASABE LA English DT Article DE Chemical amendments; Runoff; Swine manure ID POULTRY LITTER; WATER-QUALITY; COASTAL BERMUDAGRASS; AGRICULTURAL RUNOFF; FESCUEGRASS PLOTS; FORAGE MIXTURE; PHOSPHORUS; SOIL; RAINFALL; NITROGEN AB Land-applied swine manure can be an environmental concern when runoff losses of manure constituents occur. The use of chemical amendments to mitigate these losses has been investigated for poultry litter, but materials such as swine manure have received less attention in this context, particularly at the plot scale or larger. The objective of this experiment was to evaluate the impacts of aluminum sulfate (alum; Al-2(SO4)(3)), aluminum chloride (AlCl3), and ferric chloride (FeCl3) addition on runoff of selected constituents of land-applied swine manure. Manure was collected from feeder pigs fed a standard diet. Alum and FeCl3 were added at a stoichiometric ratio of 1.1:1 [Al:total P (TP)], and AlCl3 was added at a ratio of 1.3:1 [Al: TP]. The amended manure was incubated for six days prior to land application to fescue (Festuca arundinacea Schreber) plots. Simulated rainfall (100 mm h(-1) for 0.5 h of runoff) was applied to the plots on the day of application and followed by two additional simulated rainfall events at 7 d intervals. Runoff samples were collected and analyzed for dissolved reactive phosphorus (DP), TP, ammonia nitrogen (NH3-N), nitrate nitrogen (NO3-N), total Kjeldahl nitrogen (TKN), total suspended solids (TSS), fecal coliform (FC), and 17 beta-estradiol. Runoff concentrations of all constituents except NO3-N were highest for the first simulated rainfall event, approaching background levels thereafter. Relative to untreated manure, all chemical amendments were effective in reducing first-event DP, TP, and TKN concentrations. Both AlCl3 and FeCl3 reduced first-event NH3-N concentrations, and FeCl3 addition led to FC concentrations indistinguishable from the control (no manure) plots. The results indicate that these amendments have potential for promoting both environmental and agronomic benefits, implying that studies involving practicality and long-term considerations should be undertaken.

TI REMOVAL OF CATTLE MANURE CONSTITUENTS IN RUNOFF FROM NO-TILL CROPLAND AS AFFECTED BY SETBACK DISTANCE SO Transactions of the ASABE LA English DT Article DE Cattle manure; Filter strips; Land application; Manure management; Manure runoff; Nitrogen; Nutrients; Phosphorus; Runoff; Water quality ID VEGETATIVE FILTER STRIPS; NUTRIENT LOADS; SEDIMENT; PHOSPHORUS; QUALITY; GRASS; SOIL; PERFORMANCE; REDUCTION; POLLUTION AB Vegetative filter strips located at the bottom of a hillslope have been shown to substantially reduce nutrients and sediment in runoff. Cropland areas could serve a similar function. However, little scientifically derived information is available to help identify the setback distances required to effectively reduce the transport of contaminants in runoff. The objective of this study was to determine the effects of setback distance and runoff rate on the concentrations and mass transport rates of selected constituents following land application of beef cattle manure to a no-till cropland area. The study site had a residue cover of 8.84 Mg ha(-1) and a slope gradient of 6.2%. The 20 plots examined during the investigation were 3.7 m across the slope by 4.9, 7.9, 11.0, 17.1, or 23.2 m long. An initial set of rainfall simulation tests were completed to determine background concentrations and mass transport rates of selected constituents. Cattle manure was then applied to the upper 4.9 m of each plot, and additional rainfall simulation tests were conducted. A first-order exponential decay function was used to estimate the effects of setback distance on the concentrations and mass transport rates in runoff. A setback distance of 12.2 m effectively reduced the concentrations of DP, TP, NH4-N, boron, calcium, magnesium, potassium, and sulfate and the mass transport rates of DP, TP, NH4-N, boron, and potassium to background values similar to those measured on the no-manure treatment. Runoff rate was an important variable influencing each the measured constituents, with mass transport rates increasing as runoff rate increased. C1 [Gilley, J. E.; Sindelar, A.

TI REMOTE ESTIMATION OF A MANAGED PINE FOREST EVAPOTRANSPIRATION WITH GEOSPATIAL TECHNOLOGY SO TRANSACTIONS OF THE ASABE LA English DT Article DE Canopy conductance; Canopy temperature; Evapotranspiration; Model builder; NDVI; Python script; SAVI; Soil moisture; Spatial analysis; VVI ID LEAF-AREA INDEX; POTENTIAL EVAPOTRANSPIRATION; STOMATAL CONDUCTANCE; VEGETATION INDEX; LOBLOLLY-PINE; COASTAL-PLAIN; PHOTOSYNTHESIS; TRANSPIRATION; PLANTATION; COMPONENTS AB Remote sensing has increasingly been used to estimate evapotranspiration (ET) and its supporting parameters in a rapid, accurate, and cost-effective manner. The goal of this study was to develop remote sensing-based models for estimating ET and the biophysical parameters canopy conductance (g(c)), upper-canopy temperature, and soil moisture for a mature loblolly pine forest (Pinus taeda L.) in the Parker Tract in eastern North Carolina. To validate the remote sensing approach, we acquired long-term on-site eddy flux measurements, including micrometeorological variables and water and energy fluxes. Other measured and derived ET-associated parameters include forest g(c), leaf area index, canopy absorbed radiation, canopy temperature, and soil moisture. Multi-temporal cloud-free (<= 10% cloud cover) Landsat 7 ETM+ satellite images from 2006-2012 were acquired. Field data for the 2 h (12: 00 noon to 2: 00 p.m.) means were used in the model, coinciding with the image acquisition time. Individual Landsat bands (1 through 7) and developed image vegetation indices (NDVI, SAVI, and VVI) for the study site were obtained through automated geospatial models and were correlated to measured ET flux and related parameters. An excellent coefficient of determination (R-2 = 0.93, n = 42) was obtained for the upper-canopy temperature versus band 6 (thermal infrared) model. However, a low correlation (R-2 = 0.36, n = 6) was obtained for gc versus band 5 (mid-infrared) model. The correlation for soil moisture versus band 7 was poor (R-2 = 0.05, n = 42), perhaps due to heavy canopy and pine litter ground cover. However, the ET estimation model with multiple image information variables, such as bands 5 and 7, provided a good correlation (R-2 = 0.55, n = 35) with less spatial and temporal variation in the datasets, along with no data mining application in model building. Therefore, this study suggests that the remote sensing approach is promising for estimating ET with good accuracy (average model prediction residual error = 25.46 W m(-2), 6.18% of the average ET values used in the analysis) for a mature homogenous pine forest. Further work is needed to develop robust remote sensing-based ET models by including spatial variability, sound data mining, high-resolution imagery, and advanced image processing to account for potential modeling uncertainties.

Concomitantly, the agricultural community is faced with a challenge of increasing food production by more than 70% to meet demand from global population increase by the mid-21st century. This article introduces a Special Collection on Climate Change and reviews principal findings from nine articles drawn from papers presented at the 2015 ASABE 1st Climate Change. Adaptation and Mitigation Symposium. Studies present simulations of crop and livestock production-system adaptations to climate change scenarios; impacts of climate change scenarios on water resources, soil erosion and nonpoint-source pollutant source areas; regional assessment of climatic shifts; and mitigation of greenhouse gas emissions from livestock production. Articles span regional issues across the U.S., southern Asia, and Brazil. These research articles clearly indicate that climate variability and change can negatively impact food production and water resources, and that innovative strategies are needed to mitigate those negative impacts.

TI EVALUATING GREENHOUSE GAS MITIGATION AND CLIMATE CHANGE ADAPTATION IN DAIRY PRODUCTION USING FARM SIMULATION SO Transactions of the ASABE LA English DT Article DE Adaptation; Climate change; Farm model; Greenhouse gas; IFSM; Mitigation ID NITROUS-OXIDE EMISSIONS; SPECIAL TOPICS-MITIGATION; PRODUCTION SYSTEMS; METHANE; OPTIONS; MODEL; SCENARIOS AB Process-level modeling at the farm scale provides a tool for evaluating strategies for both mitigating greenhouse gas emissions and adapting to climate change. The Integrated Farm System Model (IFSM) simulates representative crop, beef, or dairy farms over many years of weather to predict performance, economics, and environmental impacts including various emissions and a farm-gate life cycle assessment of carbon, energy, water, and reactive nitrogen footprints of the feed, meat, or milk produced. To illustrate use of the model, a representative dairy farm in central New York was simulated over 25 years of recent historical weather to determine the environmental benefits and economic costs of alternative manure handling strategies. Use of an enclosed manure storage with a flare to burn the methane produced decreased the farm-gate carbon footprint of the milk produced by 20% at an increased annual cost of $42 cow(-1). Using an anaerobic digester to produce gas and electricity used on the farm reduced the carbon footprint by 19% and reduced profitability by $56 cow(-1). The addition of subsurface injection of manure along with a reduction in N fertilizer use greatly reduced ammonia emission from the farm and increased annual profit by $9 cow(-1). Climate change is projected to affect many aspects of dairy production, including growing season length, crop growth processes, harvest timing and losses, cattle performance, nutrient emissions and losses, and ultimately farm profitability. Climate projections for high and low emission scenarios were downscaled from nine general circulation models. IFSM was then used to simulate the same New York dairy farm over 25-year periods using recent, mid-century, and late century climate projected by each of the climate models. Simulations were done without and with adaptation through modified crop varieties and planting and harvest dates. Forage production normally increased with projected climate change and corn grain yields decreased, and together feed production was maintained. Warmer temperatures increased volatile loss of ammonia N, and changes in precipitation patterns increased nutrient runoff losses in surface water. The reactive N footprint of the milk produced was increased by 2% to 11% with the change in climate, but other environmental footprints were relatively unaffected. With appropriate adaptation to climate change, annual farm profitability increased by about $100 cow(-1). However, for the high emission, late century projection, profit decreased by $10 cow(-1) and the risk or annual variance in profit increased by 34%, reflecting greater annual variation in crop and animal productivity. Whole-farm and climate models provide useful tools for studying the benefits and costs of greenhouse gas mitigation and the adaptation of farms to changing climate. C1 [Rotz, C. A.; Skinner, R.

TI CLIMATE CHANGE IMPACT ON CRITICAL SOURCE AREA IDENTIFICATION IN A MARYLAND WATERSHED SO Transactions of the ASABE LA English DT Article DE Climate change; Critical source areas; Hotspots; Nonpoint-source pollution; NPS; SWAT model; Water quality; Watershed hydrology ID UNCERTAINTY ANALYSIS; CHANGE SCENARIOS; MODEL; SWAT; FLOW; SIMULATIONS; SEDIMENT; SCALE; BASIN; SOIL AB The potential impacts of climate change on critical source areas (CSAs) of surface runoff, sediments, nitrogen, and phosphorus were evaluated in an agricultural watershed of the Chesapeake Bay drainage basin, in the U.S. Northeast climate region. The SWAT model was calibrated for the study watershed and used to establish its baseline response and constituent CSAs under current climate (years 1990 to 2004). The calibrated model was then subjected to weather time series downscaled from the CMIP3 GFDL CM2.1 Atmosphere-Ocean Global Circulation Model (AOGCM) for IPCC SRES scenarios B1 (low emissions), A1B (medium emissions), and A2 (high emissions) to predict the watershed's response to climate change and identify how constituent CSAs may change under future climate (years 2046 to 2064 and 2081 to 2100). The utility of targeting best management practices (BMPs) to CSAs was assessed by computing advantage ratios that relate the fraction of watershed-generated constituents that emanate from CSAs to the fraction of watershed area occupied by these CSAs. Results indicated that, under current conditions, CSAs occupying 11% to 21% of the watershed area contribute 31% to 45% of constituents, corresponding to advantage ratios of 1.5:1 for runoff control and approximately 3: 1 for other constituents. Under climate change scenario B1, constituent yields were predicted to increase by factors of 1.5 to 1.8 at the watershed outlet, from an increase in annual rainfall of 25% predicted by the AOGCM, over current conditions. Under scenarios A1B and A2, constituent yields were predicted to increase by factors of 1.8 to 2.3 over current conditions, from an increase of 30% in annual rainfall. The area of runoff CSAs was predicted to more than triple with climate change, leading to negligible advantage of targeting runoff control BMPs to CSAs under future climate. The areas of sediment, nitrogen, and phosphorus CSAs were predicted to increase by factors of 2 to 3 with climate change, causing BMP-targeting advantage ratios to decrease from approximately 3: 1 (baseline) to 2: 1 (future). While advantage ratios for suspended and dissolved constituents remain favorable, even under future climate, the much larger area predicted to be covered by CSAs (2 to 3 times current values) suggests that stakeholder involvement and community-oriented participatory approaches will be increasingly important for achieving Chesapeake Bay TMDLs with climate change.

We focus on homogeneous and earth fill levee to simplify this first implementation. The first part of this study reveals the ability of this method to represent simultaneously both formations of the breach and the scour hole at the rear of the levee. The resistance or no of the levee seems consistent with the resistance of the soil material given by a standard classification. But this first part has showed that the lateral development of the breach cannot be represented. In the second part of this study, a simply widening of the breach method based on continuous surface erosion process, has been implemented. The comparison with large scale experiments which has been made, shows that both dynamics of the breach formation and the width are not correctly estimated with the only one surface erosion process. Further developments have to be done to integrate the headcut erosion process and mass failure as sliding of the sides of the breach or undercutting.

Area of study: The study area is the Aralar Forest in Navarra (Northern Iberian Peninsula). Material and methods: The amount of dead wood by component (downed logs, snags, stumps and fine woody debris) was inventoried in 51 plots across a chronosequence of stand ages (0-120 years old). Main results: The average volume and biomass of dead wood was 24.43 m(3) ha(-1) and 7.65 Mg ha(-1), respectively. This amount changed with stand development stage [17.14 m(3) ha(-1) in seedling stage; 34.09 m(3) ha(-1) in pole stage; 22.54 m(3) ha(-1) in mature stage and 24.27 m(3) ha(-1) in regular stand in regeneration stage], although the differences were not statistically significant for coarse woody debris. However, forest management influenced the amount of dead wood, because the proportion of mass in the different components and the decay stage depended on time since last thinning. The formula based on intersection diameter resulted on the smallest coefficient of variation out of seven log-volume formulae. Thus, the intersection diameter is the preferred method because it gives unbiased estimates, has the greatest precision and is the easiest to implement in the field. Research highlights: The amount of dead wood, and in particular snags, was significantly lower than that in reserved forests. Results of this study showed that sampling effort should be directed towards increasing the number of transects, instead of increasing transect length or collecting additional piece diameters that do not increase the accuracy or precision of DWM volume estimation.

Production and processing of fresh-cut lettuce is continually evolving, offering more products and becoming more efficient. Breeding new lettuce cultivars specialized for this market can offer further improvements, but has received attention only within the last decade. Improvements to plant morphology can increase yield, quality, and production efficiency. Crops must meet high stringencies for internal defects and cultivars specialized for fresh-cut often need enhanced levels of resistance to these problems. Modified atmosphere packages (MAP) are used to reduce browning or pinking of cut surfaces. Development of cultivars that do not discolor could minimize or eliminate the need for MAP. New cultivars with longer shelf-life could reduce waste and increase the distribution system's efficiency. The nutritional content of fresh-cut lettuce can decline after processing. Research that addresses this issue may improve the popularity of fresh-cut lettuce. Lettuce and its wild relatives have genetic variation for plant morphology, quality, and resistance to abiotic stresses that can be used to breed improved lettuce cultivars. Quantitative trait loci (QTL) mapping has determined the inheritance of many traits useful for the fresh-cut industry. This knowledge should be used to devise molecular breeding methods that accelerate cultivar development. These approaches are particularly useful for improving postharvest traits, since phenotypic assays for these traits are often laborious and destructive, require specialized equipment, and typically test large numbers of plants.

Fibrous carrot dices are difficult to detect, and are highly problematic when found in ready-to-eat infant food, where they might represent a choking hazard (safety concern). A Visible/Near-InfraRed (Vis/NIR) hyperspectral imaging (321-1088 nm) system was used to obtain a set of 520-images per sample, from 1233 sections (samples). Carrots were collected during the 2013 and 2014 harvesting seasons. Classification accuracy per sample was evaluated by comparing the classes obtained using Vis/NIR hyperspectral images against their undesirable fibrous tissue class, based on the industry-simulated invasive quality assessment (% of fiber). Class-0 represents fibrous-free samples, and class-1 denotes samples containing fibrous tissue. After Vis/NIR image preprocessing, cropping, selection, and segmentation, 3135 grayscale intensity and textural features were extracted per sample from 15 selected Vis/NIR images. A 4-fold cross-validation Neural-Network-Classifier with a performance accuracy of 86.4 +/- 2.1% was developed using 140 relevant features, which were selected using a sequential forward selection algorithm with the Fisher discriminant objective function. Findings showed that this methodology is an objective, accurate, and reliable tool to determine the presence of undesirable fibrous tissue in processing carrots, and would be applicable to an automated noninvasive inline sorting system.

They are often pre-trimmed, cut and packaged, and while usually consumed cooked, they may also be eaten raw in salads. Salmonella is an enteropathogenic bacterium that can adapt to adverse environmental conditions. Although it has been reported that Salmonella-infected plants are asymptomatic, wilting, yellowing, biomass loss and a hypersensitive response (HR) have been demonstrated in plant tissues. The aim of this study was to investigate plant tissue response to different strains of Salmonella enterica in two cultivars of cactus as well as the persistence of Salmonella strains in the tissue. The top of pads (20-25 cm) of greenhouse-grown (20 degrees C, 51.2% RH) 'Milpa Alta' and 'Atlixco' cultivars were inoculated with water (control) or 1 mL 8.0 log CFU of strains Salmonella typhimurium (N4), Salmonella javiana (N7) isolated from nopalitos, and laboratory strain S. typhimurium ATCC 23564 (Sal 4). Cladodes (n=20) from each cactus cultivar were sampled and evaluated every 24 h for 4 days starting 6 h after inoculation for visual symptoms, color change and Salmonella persistence in the tissue. Data were subjected to analysis of variance with mean separation by T test (alpha=0.05). Color and appearance changed in longitudinal sections of pads of both cultivars only in the area where the bacteria were infiltrated and this could be considered to be a hypersensitive response. All three Salmonella strains persisted 48 h or longer. C1 [de la Riva-Alvarez, S. L.; Hernandez-Anguiano, A. M.] Postgrad Fitosanidad Fitopatol Colegio Postgrad, Montecillo, Edo De Mexico, Mexico.

TI Biological differences that distinguish the 2 major stages of wound healing in potato tubers SO PLANT SIGNALING & BEHAVIOR LA English DT Article DE Closing layer; meristematic; suberization; S-phase; wound periderm ID INDUCED SUBERIZATION; CLOSING LAYER; CELL-CYCLE; SUBERIN; BIOSYNTHESIS; GENES AB The two stages of potato tuber wound healing, closing layer formation (CLF) and wound periderm formation (WPF), have critical biological differences. The first stage, CLF, involves early induction of DNA synthesis and nuclear division in the absence of cell division. The transition phase from CLF to the second stage, WPF, is marked by a transient decrease in expression of suberin-specific genes. The second stage involves cell division. Although biologically active cytokinins (CKs) are not present in quantifiable amounts during this stage, the presence of precursor and catabolic products suggest the presence of trace amounts of active CKs that, in conjunction with increased auxin (indole acetic acid), provide necessary signals for meristematic activity. Augmenting these putative trace amounts with exogenous biologically active CK inhibits WPF; this suggests that the CK requirements for meristematic activity are finely controlled and sensitive to extremely low concentrations. Evidence is discussed for separate biological processes and signals that distinguish the 2 stages of wound healing.

Plants were fertilized with 30 kg hat N at transplanting, 10 kg hat N at 29 days after transplanting (DAT) during early leaf growth, and with 0, 20, 40 and 60 kg hat N at 51 DAT at the initiation of bulbing. The root system of plants in each treatment were concentrated in the top 0.1 m of soil and limited to 0.3 m depth but neither root length density nor rooting depth were affected by N application during later stages of bulb development. Leaf and bulb dry matter, on the other hand, increased linearly with N rate during bulb growth (85 DAT) and at harvest (114 DAT), respectively. Soil nitrate-N (NO3-N) at 0-0.3 m depth likewise increased linearly with N rate during bulb growth but declined from 15-30 mg kg(-1) at bulbing to <10 mg kg(-1) in each treatment by harvest. A substantial amount of N in the plants, which ranged from 302-525 mg, was taken up from the soil. Application of 60 kg ha(-1) N resulted in luxury consumption. Yield (fresh bulb weight) increased from 0.19 kg plant(-1) with no N at bulbing to as much as 0.28 kg plant(-1) with 60 kg hat N. Bulbs harvested from plants fertilized 40-60 kg hat N averaged 8.2-8.5 cm in diameter, while those from plants with no N at bulbing averaged only 7.2 cm in diameter. Application of N fertilizer is thus recommended at bulbing to increase N uptake, yield, and bulb size of intermediate-day onions, particularly in dry Mediterranean climates where many onions are produced. Other components of quality, including neck diameter, bulb water content, total soluble solids, and juice pH, were not affect by N applied at bulbing. C1 [Machado, R. M.

Close association of genetic markers with genes controlling economically important traits allows for indirect selection, avoiding often time-consuming and expensive phenotypic evaluations. As a result, detailed genetic maps have been created for almost all economically important plants and many important traits have been tagged. Onion has lagged behind other major crops because of relatively few public-sector researchers, long generation time, and high cost of developing segregating families. With the advent of next generation DNA sequencing, large numbers of codominant markers have become available. The onion research community should now work collaboratively to produce and share useful genetic and genomic resources for onion, including diverse doubled-haploid lines, readily accessible sequence and bioinformatic resources, and large segregating families for detailed genetic mapping and phenotyping C1 [Havey, M.

This makes kernel moisture content determination laborious and limits efficiency during peanut drying. For field testing during the 2013 and 2014 peanut harvest seasons, a microwave moisture sensor was placed in several 45-ft (13.7-m) drying semi-trailers at a buying point in central Georgia to monitor kernel moisture content as the peanuts dried. Laboratory investigation of the accuracy of the portable microwave moisture sensor showed that peanut kernel moisture content can be determined from measurements on unshelled peanuts with a standard error of performance <= 0.55% moisture content when compared to the reference oven-drying method. A comparison was also performed between the microwave sensor and the official moisture meter during field testing. Results showed that there was a 2.3% difference in initial kernel moisture content determination and a 0.8% difference in ending kernel moisture content determination between the two. Overall evaluation demonstrated that the accuracy of the microwave moisture sensor and its provision of in-shell kernel moisture content would make it highly effective in the peanut drying process.

In laboratory studies, urease inhibitors have been effective in reducing NH3 emissions from beef cattle manure, however there has been little testing under field conditions. An experiment was conducted to evaluate the effectiveness of the urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) for reducing NH3 flux from the pen surface at a beef cattle feedyard. NBPT was applied to six feedyard pens for 42 d (April-June) at rates of 0, 1, 2, 4, 8, and 40 kg ha(-1). NH3 flux was quantified using a flow-through flux chamber and chemiluminescence NH3 analyzer. Nutrient concentrations in the manure were monitored over the 42 d period. There was high spatial variability in NH3 emissions within individual pen, and NH3 flux was lognormally distributed (geo. mean= 1,618 mu g m(-2) min(-1); geo. std. dev. = 2.52 mu g m-2 min(-1); range 512 to 14,993 g m-2 min(-1)). No statistical differences were observed in NH3 flux among the different NBPT application rates due to the high spatial variability in NH3 flux within pens. A post-experiment power analysis revealed that more than 500 individual flux chamber measurements would be needed per pen in order to detect a 10% difference in treatment means, an impractical task given the time and labor required for flux chamber measurements. At the completion of the six-week experiment, the 2 and 40 kg ha(-1) NBPT treatments retained 9% and 20% more total Kjeldahl nitrogen (TKN) in the manure than the control, respectively. In future research evaluating the long-term effectiveness of urease inhibitors for reducing NH3 emissions from open-lot beef cattle feeding operations, we recommend that micrometeorological methods would be more appropriate than small flux chambers.

Projecting future climate conditions harbors several sources of uncertainty that, in turn, lead to uncertainty in projected soil erosion rates. Awareness of these uncertainties is essential to the development of flexible and affordable conservation and adaptation measures that remain effective over the broad range of climate projections. In this study, three climate-associated sources of uncertainties were selected to examine their effect on projected soil erosion for winter-wheat cropland in central Oklahoma. Forty soil erosion distributions representing various combinations of two emission scenarios, ten climate projection models (incl. downscaling), and two storm intensification alternatives were developed and evaluated. The total uncertainty range of 40 projected soil erosion distributions was 2.1 to 18.2 Mg ha(-1) yr(-1) at the median, and 25.0 to 114.0 Mg ha(-1) yr(-1) at the 10% Probability of Exceedance level. For the selected climate change scenarios, climate models, and Oklahoma climate conditions, the uncertainty due to imperfect prediction tools (climate models, downscaling methods) and model choices (storm intensification) was found to be sizably larger than the inherent uncertainty associated with the realization of a future climate outcome (emission scenario). It was concluded that uncertainties in projected soil erosion rates can potentially be large and should be given full consideration in planning future conservation needs. C1 [Garbrecht, J.

Insect pitfall traps were used to measure naturally-occurring populations of stored product insects. Results show uniform distribution of temperatures in the headspace until the area immediately above the top of the grain mass. In general, suction aeration cooled the top portion of the grain mass more quickly than pressure aeration, based on measured temperatures, days above specified temperature thresholds, and total heat accumulations above those thresholds, for each of the three years. Populations of Cryptolestes ferrugineus (Stephens), the rusty grain beetle, and Tribolium castaneum Herbst, the red flour beetle, were generally at least 2x to 4x greater in pressure versus suction aeration, depending on the specific sampling date, during the first two years of the study. An extensive infestation that developed during the third year may have diminished the effects of aeration. The other two insect species caught in abundance were two fungus-feeding insects, Typhaea stercoria (L.), the hairy fungus beetle, and Ahasverus advena (Waltl), the foreign grain beetle. Mixed effects were observed for these two species under the two aeration treatments. Results show that suction aeration may be preferable over pressure aeration, but afternoon temperatures lead to a buildup of heat in the headspace that affected the temperature of the upper layer of the grain mass. Installing a thermostat for controlled aeration utilizing the headspace temperatures as a set point instead of relying on outside ambient temperatures may increase efficiency of suction aeration.

TI CORRELATING BULK DENSITY (WITH DOCKAGE) AND TEST WEIGHT (WITHOUT DOCKAGE) FOR WHEAT SAMPLES SO APPLIED ENGINEERING IN AGRICULTURE LA English DT Article DE Dockage; HRW; SRW; Stored grain inventory; Test weight; Wheat ID STORAGE STRUCTURES; GRAIN SPREADERS; CORN AB In grain bins, the compaction of stored grain is caused by the overbearing pressure of the bulk material in the bin. To predict the amount of grain in the bin, compaction values must be determined based on the average bulk density (BD) of the stored material. However, BD is determined following the Federal Grain Inspection Service (FGIS) guidelines for measuring test weight (TW), which require that dockage be removed prior to measuring wheat TW. Thus, this creates a problem for predicting grain compaction and conducting inventory studies, because the average BD of the grain in a bin for these calculations should include dockage. Therefore, regression models between the TW without dockage and the BD with dockage were obtained based on the reported scale data during wheat harvest from three elevators located in Kansas and Oklahoma. A power model was used to predict BD with dockage when TW without dockage and dockage levels are given. Laboratory samples of HRW and SRW wheat with dockage levels ranging from 0.05% to 5% showed a second order polynomial trend when plotted against decrease in BD with dockage values compared to TW without dockage. These results will be crucial for determining grain packing inventory parameters for HRW wheat bins. C1 [Bhadra, R.; Boac, J. M.; Maghirang, R.

A study was conducted to evaluate the potential of an innovative biocomposite material patented by Ecovative Design LLC (Green Island, N.Y.) for use in commercial products and packaging. The biocomposite material utilizes the fungus mycelium as a matrix to bind cellulosic plant fibers. The test samples were manufactured with different fiber-fungal strain combinations, using cotton ginning waste and hemp pith as core material and fiber fabric on the surface. The physico-mechanical properties of the biocomposites were evaluated to develop a thorough understanding of the material which may lead to future applications. The properties evaluated included specific gravity, surface hardness, water absorption, coefficient of linear thermal expansion, and resistance to tension and compression. The density profile results indicated that the material is extremely light, buoyant, and highly hydrophilic. Surface hardness test showed that the material has a soft outer surface with high elasticity. The tensile and compression properties showed the material can be used in targeted packaging applications where lightweight, resiliency, and biodegradability are desirable. C1 [Ziegler, A.

The papers were presented as part of the Fifth Fire in Eastern Oak Forests Conference in Tuscaloosa, Alabama, USA, in 2015. The topic of fire in Eastern oak ecosystems is one that has received insufficient interest from the broader fire ecology community. Specific papers in this issue address the historical role of fire in the region, the response and adaptations of plant and animal species to fire and fuels treatments, and the future of these important ecosystems under a future of global change. We hope that this issue provokes future research on the past, present, and future of fire in eastern North American oak ecosystems. C1 [Varner, J.

TI REPEATED APPLICATION OF FUEL REDUCTION TREATMENTS IN THE SOUTHERN APPALACHIAN MOUNTAINS, USA: IMPLICATIONS FOR ACHIEVING MANAGEMENT GOALS SO FIRE ECOLOGY LA English DT Article DE fuel reduction; mechanical fuel reduction; oak regeneration; open woodland; prescribed fire; restoration ID MIXED-OAK FORESTS; HARDWOOD FORESTS; PRESCRIBED FIRE; REGENERATION; MASTICATION; COMMUNITIES; LANDSCAPE; BEHAVIOR; REGIMES AB Fire and resource managers of the southern Appalachian Mountains, USA, have many questions about the use of prescribed fire and mechanical treatments to meet various land management objectives. Three common objectives include restoration to an open woodland, oak regeneration, and fuel reduction. This paper provides information about reaching each of these three management objectives by using prescribed burning (B), mechanical fuel reduction (M), and a combination of both fire and mechanical treatment (MB). The southern Appalachian site of the National Fire and Fire Surrogate study has been burned three times and a mechanical treatment has been conducted twice since 2002. Stand structure was changed by each active treatment but restoration to an open woodland was not achieved by any. The MB treatment units developed the desired overstory structure but heavy sprouting of woody species in the understory prevented the establishment of a diverse herbaceous forest floor. Oak reproduction was increased by all active treatments, largely by sprouting of top-killed stems. The degree of fuel reduction differed by treatment. All treatments reduced the shrub layer, thus reducing the vertical fuel component. The B and MB treatments reduced most fuels and likely reduced the severity of a subsequent wildfire. We conclude that additional burning is required to meet each management objective, and that fires should be conducted more frequently, in different seasons, or in combination with other treatments.

TI SUITES OF FIRE-ADAPTED TRAITS OF OAKS IN THE SOUTHEASTERN USA: MULTIPLE STRATEGIES FOR PERSISTENCE SO FIRE ECOLOGY LA English DT Article DE bark thickness; fire regimes; fuel moisture; functional traits; litter flammability; Quercus; trait associations ID PINUS-PALUSTRIS ECOSYSTEMS; EASTERN UNITED-STATES; BURNING CHARACTERISTICS; NORTH-AMERICA; WOODY-PLANTS; FOREST; ECOLOGY; FLAMMABILITY; COMMUNITIES; RESPONSES AB Fire is integral to the functioning of terrestrial ecosystems of the southeastern USA and is a strong selective force on plant species. Among woody plants, oak species (Quercus spp. L) have diverse life history traits that appear to reflect their evolution in this fire-prone region. Oaks also occur across wide gradients of fire frequency and intensity, from annually burned savannas to fire-protected forests. As such, oak functional traits are presumed to reflect adaptations to acquire limited resources (i.e., "physiological traits") or survive environmental stress (i.e., "protective traits"). Oak functional traits may also influence fire regimes (i.e., via "flammability traits") by altering fire behavior through effects on fuels and their combustion. We synthesized evidence from ecophysiological measurements, laboratory burning and drying experiments, and field experiments to determine the suites of functional traits that reflect fire adaptive strategies in eight Southeastern oaks for which abundant data were available. We found strong correlations among Principal Components Analysis axes for flammability (litter burning and drying), protective (bark and wound responses), and physiological (growth) traits. The eight oaks clustered into three strategies: 1) pyrophytic species that produce highly flammable leaf litter, accrue thick bark rapidly, close wounds rapidly, and grow slowly; 2) mesophytic species that produce low flammability litter, have thin bark, and are fast growing; and 3) fire-avoider species with a mixture of traits from the two extremes. This synthesis clarifies the relative pyrophily of Southeastern oaks and suggests how suites of fire-related traits influence fire regimes and species habitat preferences. C1 [Varner, J.

We quantified the temporal variability in fire regimes and described the spatial dependence of fire intervals through the analysis of multi-century fire scar records (8 study sites, 332 trees, 843 fire scars) derived from two historically post oak (Quercus stellata Wangenh.) woodland landscapes. Despite large differences in fire environment conditions, study sites (similar to 1 km(2)) burned frequently (mean fire interval [MFI] <= 10 yr) before Euro-American settlement (pre-EAS), with sites in Tennessee showing higher overall fire frequency than sites in Oklahoma, USA. PreEAS MFIs decreased exponentially with increasing spatial extent from individual trees (similar to 1 m(2)) to landscapes (similar to 100 km(2)). The relationship between MFI and spatial extent may help to explain how historical observations of annual burning could be recorded in woodlands, when experimental studies suggest that this is too frequent for tree recruitment. Further investigations of spatial dependence of fire intervals would improve our ability to relate historical and experimental fire data to present day fire prescriptions, and vice versa.

Bankhead National Forest ID EASTERN UNITED-STATES; FUEL REDUCTION TREATMENTS; CUMBERLAND PLATEAU; SHELTERWOOD STANDS; OAK FORESTS; UPLAND OAK; FIRE; REGENERATION; PATTERNS; USA AB Restoration of hardwood-pine (Pinus L.) mixedwoods is an important management goal in many pine plantations in the southern Cumberland Plateau in north-central Alabama, USA. Pine plantations have been relatively unmanaged since initiation, and thus include a diversity of hardwoods developing in the understory. These unmanaged pine plantations have become increasingly vulnerable to insects, and management activities were initiated to facilitate transition towards hardwood- pine mixedwoods. We evaluated a combination of thinning and prescribed fire prescriptions in a randomized complete block design with a 3 x 3 factorial treatment arrangement and four replications of each treatment. Treatments were combinations of thinning to three residual basal areas (no thin, light thin to 17.2 m(2) ha(-1), heavy thin to 11.5 m(2) ha(-1)) and three prescribed burn applications (no burn, one burn to be repeated every 9 years, three burns repeated every 3 years). Burning without thinning altered stand structure by reducing overstory stem density by 15 %, whereas thinning without burning reduced density by 70 % and burning coupled with thinning resulted in reduced overstory trees by 72 %. Frequent fire had the greatest impact on midstory structure and regeneration. Midstory stem density was reduced by 90 % following thinning and burning. Oaks (Quercus L.) and red maple (Acer rubrum L.) were the most common understory species after thinning only, burning only, and thinning combined with burning. There were more oak and red maple seedling sprouts following frequent burning. Currently, > 75 % of red maple sprouts dominate the regeneration, compared to only 40 % of the oaks. Although the treatments have accelerated the transition toward hardwood-pine mixedwoods, the fate of oak and which hardwood species will be dominant in the future remains uncertain.

The relative differenced normalized burn ratio (RdNBR) is a commonly used severity index in California forests, and is typically divided into four categories: unchanged, low, moderate, and high. RdNBR is often calculated twice. from images collected the year of the fire (initial assessment) and during the summer of the year after the fire (extended assessment). Both collection times have been calibrated to field measurements, but field data with both pre-fire and post-fire observations of matched plots are typically not available. This study uses a large network of field plots (n = 175) that was surveyed the year of and one year after a large wildfire in the central Sierra Nevada, USA, to quantify forest structure, mortality, and fire effects within fire severity categories from both the initial and extended RdNBR assessments. Most plots were classified in the same severity category in both assessments, particularly when mortality was high. Comparing initial and extended assessments, plots with lower pre-fire basal area were more likely to be classified at lower severity in the extended assessment, while plots with greater tree density were more likely to be classified at higher severity. High-severity plots had significantly greater pre-fire density of small trees. The high-severity category clearly captured stand-replacing fire effects (>95 % basal area mortality, >99 % tree density mortality), with typically all trees exhibiting high levels of crown consumption and scorching. In other severity categories, most large-sized and intermediate-sized trees survived, and moderate-severity fire favored survival of shade-intolerant species. Results suggest that both the initial and extended RdNBR assessments give an accurate representation of forest structural change in mixed-conifer forests following fire, particularly those of high severity.

Lawson; ponderosa pine; stand-replacing fire effects ID PONDEROSA PINE FORESTS; MIXED-CONIFER FOREST; OLD-GROWTH FORESTS; FRONT-RANGE; WILDFIRE SEVERITY; SIERRA-NEVADA; SOUTHERN CASCADES; WESTERN US; CALIFORNIA; LANDSCAPE AB There is considerable interest in evaluating whether recent wildfires in dry conifer forests of western North America are burning with uncharacteristic severity. that is, with a severity outside the historical range of variability. In 2002, the Hayman Fire burned an unlogged 3400 ha dry conifer forest landscape in the Colorado Front Range, USA, that had been the subject of previous fire history and forest age structure research. We opportunistically leveraged pre-existing data from this research, in combination with post-fire aerial imagery, to provide insight into whether the Hayman Fire's patterns of high-severity, stand-replacing fire effects were uncharacteristic. Living old overstory trees were well distributed and abundant in the landscape before the Hayman Fire, despite the fact that some stand-replacing burning had been a component of the landscape's historical mixed-severity fire regime. Of 106 randomly selected stand polygons that were sampled for the age of the oldest living overstory tree prior to the fire, 30% contained only trees <200 yr, while 70% contained at least one tree >200 yr and 29% contained at least one tree >400 yr. Following the Hayman Fire, only 5% of the polygons contained any living trees; these polygons were all immediately adjacent to the reservoir in the center of the landscape. At most, 4 % of the polygons contained one or more trees >200 yr post fire, and 3 % contained one or more trees >400 yr. The nearly complete loss of old trees, most of which were located in areas with evidence of past non-stand-replacing burning, leads us to conclude that the amount and extent of stand-replacing burning within the Hayman Fire were uncharacteristic for this landscape over at least the last two to four centuries.

SO FIRE ECOLOGY LA English DT Article DE Acer; climate change; drought; prescribed fire; Quercus ID CANOPY ACCESSION STRATEGIES; EUROPEAN VEGETATION CHANGE; UNITED-STATES; CLIMATE-CHANGE; NORTH-AMERICA; PRESCRIBED FIRE; SOUTHERN APPALACHIANS; IMPORTANT DRIVER; HARDWOOD FOREST; STAND STRUCTURE AB The pace of environmental and socioeconomic change over the past 100 years has been rapid. Changes in fire regimes, climate, and land use have shaped the structure and function of most forest ecosystems, including oak (Quercus spp. L.) forests in the eastern United States. New stressors such as air pollution and invasive species have contributed to and interacted with climate and fire to alter current forest conditions. While changing fire regimes have altered species composition of the current forest, oak regeneration is constrained by many factors that may affect future forests. Over the remainder of the twenty-first century, an accelerating pace of climate and socioeconomic changes will influence the future range of variation in Eastern oak forests. Some of these impacts will be direct, such as changes in tree growth rates, while other impacts will be indirect, such as new disturbance regimes. While it is likely that fire will be important in shaping oak forests in the twenty- first century, it is less clear exactly what that role will be. For example, it is uncertain whether our current scientific knowledge on the use of prescribed fire in oak forests will be applicable under novel climate and changing socioeconomic conditions. We propose that the combination of climate change, wildfire, and other disturbances will create stand conditions that favor oaks with or without management. However, management intervention (e.g., prescribed fire, thinning, or a combination) could reduce wildfire hazard, particularly in the wildland-urban interface, and create more desirable stand conditions that are resilient to future stressors such as changing precipitation patterns and warmer temperatures.

TI Modeling of n-Hexadecane and Water Sorption in Wood SO FOREST PRODUCTS JOURNAL LA English DT Article ID SOFTWOOD CHIPS; ABSORPTION; DIFFUSION; PRESSURE; PENETRATION; DISTILLATE AB Contamination of wooden framing structures with semivolatile organic chemicals is a common occurrence from the spillage of chemicals, such as impregnation with fuel oil hydrocarbons during floods. Little information is available to understand the penetration of fuel oil hydrocarbons into wood under ambient conditions. To imitate flood and storage scenarios, the sorption of n-hexadecane (representing fuel oil hydrocarbons) and water by southern yellow pine was studied using gravimetric techniques at ambient temperature and pressure. The sorption curves obtained. had three distinct regions, reflecting three different sorption phases. Lower sorption coefficients were obtained for nonpolar n-hexadecane than for water, leading to n-hexadecane maximum mass uptake values being half those of water. Lower penetration values were obtained for epoxy-coated wood compared with uncoated wood, apparently because of the inaccessibility of diffusion paths along the wood lateral surface and slower air removal from tracheids. Two models were introduced to fit the observed sorption curves into a single algebraic equation, a diffusion (Fickian) model and an empirical (non-Fickian) equation. Effective diffusion coefficients were determined under the Fickian model, resulting in ca. 10(-7) m(2)/s, 10(-8) m(2)/s, and 10(-10) to 10(-11) m(2)/s diffusion rates for sorption in Phases 1, 2, and 3, respectively. The proposed non-Fickian model was based on first order kinetic constants for the second sorption phase and fit the experimental data throughout all three phases. The two models were shown to corroborate each other by demonstrating that the effective surface areas of wood blocks calculated using both models' parameters were consistent with the corresponding expected physical values.

The two and a half-day symposium was held on October 13-15, 2015, in Madison, Wisconsin, United States. The 2015 BHBS featured new and emerging research further bolstering the positive biological effects of berry consumption on human health, performance, and disease prevention. The papers presented at the 2015 BHBS consisted of invited papers from an international group of leading berry researchers, as well as poster abstracts. Oral sessions were organized around themes including heart health, cancer prevention, gut health/gut microflora, brain aging, metabolism, and berry compositional chemistry. These thematic health areas, while not exhaustive, encompass the more prominent research success stories on berries, the vast majority of which are backed by published animal and human studies. Similar to the past meetings, the research findings at the 2015 BHBS primarily focused on blackberries, blueberries, black raspberries, cranberries, red raspberries, and strawberries. However, research on other berry fruits, including chokeberry (aronia berry), cloudberry, blue honeysuckle berry, bilberry, jamun berry, and elderberry, was also featured as was data on major classes of berry polyphenols/phytochemicals including anthocyanins and other flavonoids and their in vivo derived metabolites. The BHBS continues to be a leading forum for interactions between scientists and berry industry stakeholders. The cluster of papers in this issue represents a snapshot of presentations at the 2015 BHBS which support the positive biological effects of berries on human health and diseases.

A number of berry fruits high in polyphenols are known to ameliorate age-related declines in cellular, cognitive and behavioral function in rats. OBJECTIVES: This study evaluated the effectiveness of a red raspberry-supplemented diet on age-sensitive measures of learning, memory and motor performance in aged (19 mo) F344 rats. METHODS: Red raspberry extract was prepared from fresh whole fruit and incorporated in standard rodent chow to create a 2% diet. Following ten weeks on a control or 2% raspberry diet, cognitive and motor performance was assessed using the Morris Water Maze (MWM) and a battery of five psychomotor tasks. RESULTS: The supplemented diet significantly improved performance on three of the five motor tasks, but did not affect MWM performance. Specifically, old rats fed the 2% raspberry diet had significantly better performance on the rod and plank walks, which measure psychomotor coordination and balance, and on the inclined screen, which measures muscle tone, strength, stamina and balance. CONCLUSIONS: Given that falls are the number one health hazard for otherwise healthy older adults, these results may have important implications for increasing healthy aging.

TI A Study of the Flow Field Surrounding Interacting Line Fires SO JOURNAL OF COMBUSTION LA English DT Article ID FLAME TILT CHARACTERISTICS; HYDROCARBON POOL FIRES; WIND-BLOWN FLAME; CROSS AIR-FLOWS; GLOBAL CORRELATION; SURFACE FIRES; BURNING RATE; PLUME; MODEL; CONVECTION AB The interaction of converging fires often leads to significant changes in fire behavior, including increased flame length, angle, and intensity. In this paper, the fluid mechanics of two adjacent line fires are studied both theoretically and experimentally. A simple potential flow model is used to explain the tilting of interacting flames towards each other, which results from a momentum imbalance triggered by fire geometry. The model was validated by measuring the velocity field surrounding stationary alcohol pool fires. The flow field was seeded with high-contrast colored smoke, and the motion of smoke structures was analyzed using a cross-correlation optical flow technique. The measured velocities and flame angles are found to compare reasonably with the predicted values, and an analogy between merging fires and wind-blown flames is proposed.

TI Use of Cover for Concealment Behavior by Rainbow Trout: Influences of Cover Structure and Area SO NORTH AMERICAN JOURNAL OF FISHERIES MANAGEMENT LA English DT Article ID JUVENILE ATLANTIC SALMON; DIEL ACTIVITY PATTERNS; WINTER CONCEALMENT; CHINOOK SALMON; ONCORHYNCHUS-TSHAWYTSCHA; BROWN TROUT; HABITAT USE; SIZE; SELECTION; SHELTER AB Concealment behavior by stream salmonids can benefit individuals and populations, but the availability of concealment habitat may be limited in many streams. Quantification of concealment habitat is likely to be a valuable process in the management of stream salmonids; it is a necessary step in the application of spatially explicit, individual-based models that incorporate concealment behavior. We conducted a series of laboratory experiments with Rainbow Trout Oncorhynchus mykiss to aid in the identification and quantification of concealment habitat. Overall, individual Rainbow Trout about 12 cm FL readily used low-ceiling spaces with one, two, or four openings for concealment. Structures analogous to weakly undercut banks were used less. Mean use of different cover types was less variable in an experiment in which groups of three fish were tested. Individuals in groups rarely shared cover spaces, even though in another experiment individual fish readily occupied spaces less than 25% of the area of the spaces they rarely shared. One cover structure that was not preferred in a simple choice experiment was used as much as the preferred structure when the former was the only cover available, indicating that habitat preference experiments provide limited information when the issue is whether fish are willing to use specific habitats.

Lack of availability of potential genotypes is one of the stress main factors that the farmer community faces. A complete diallel mating design was used to study combining ability of a set of upland cotton genotypes developed in Pakistan. Five parents namely, IR-NIBGE-3, FH-166, KZ-189, MS-40 and B-557 were hybridized in a glasshouse and F-1 seeds with five parents were planted in field conditions. The combining ability analysis revealed that IR-NIBGE-3 is a good general combiner for gin turnout and fiber strength, while KZ-189 and FH-166 are good general combiners for number of bolls per plant, yield of seed cotton and fiber length. The combination of FH-166 x B-557 and MS-40 x B-557 exhibited the best specific combining ability for number of bolls per plant, yield of seed cotton and gin turnout; whereas combination of KZ-189 x B-557 and MS-40 x KZ-189 were the best for fiber length and fiber strength, respectively. Positive and significant reciprocal effects signify the role of female parents for their use in hybridization. SCA variance was greater than GCA variance for all traits indicating the importance of non-additive effects in genetic control of these traits. This study indicates that this population can be used for selection of transgressive segregants for fiber and yield related traits and superior parents can be used in hybridization programs.

Remote sensing techniques, therefore, has been utilize to overcome these obstacles with good success. Normalize Difference Vegetation Index (NDVI) based models are considered to be most effective and utilized technique in crop yield assessment and can provide up to field level assessment. This research utilize MODIS based 250m daily NDVI to estimate corn yield in 4 Agricultural Statistics Districts (ASD) in Iowa state. Corn is considered the primary crop in the US accounting for 90% of the total feed grains, hence utilized to be study in this research. Linear regression model was derived between NDVI curve and corn yield using all counties within the 4 ASD between years 2000 to 2014. The regression model showed statistically significant relation between NDVI curve and corn yield with coefficient of deterministic (R-square) over 0.80 in all 4 ASD. Similarly validating the model using new 2015 yield, the average predictability error was between 5 to 7 percent. C1 [Shrestha, Ranjay; Di, Liping; Yu, Eugene G.; Kang, Lingjun; Li, Lin; Rahman, Md.

It is the base model for Monitoring Agricultural ResourceS (MARS) Crop Growth Monitoring System (CGMS) in operational use for yield estimation in European Union. The model is of great potential in providing effective modeling of crops in the United States. The first step to adopt the model to be fit for applications to crop modeling in the US is to provide required parameters at any region and any time in the United States. In this study, several data sources have been identified and enabled to be readily fed into the models through standard, open, automatic, Web-based, online geospatial Web services. These Web services have the flexibility of accessing, re-processing, and customization to the models at different levels from regional (i.e. counties, agricultural statistic districts) modeling to point (i.e. pixel) modeling because of their spatiotemporal capabilities. Three major data sources and parameters for WOFOST model are meteorological data, crop data, and soil data. Soil data are accessed and customized through standard Web Feature Service (WFS) request to the online services of Soil Survey Geographic Database (SSURGO). Crop data are retrieved from Web Coverage Service (WCS) from CropScape that serves Cropland Data Layer (CDL). Assimilated data from ground observations provide meteorological observations. Meteorological observations are retrieved online through public service application programming interface (API) of DayMet that provide gridded estimates of daily weather parameters for North America, including daily continuous surfaces of minimum and maximum temperature, precipitation occurrence and amount, humidity, shortwave radiation, snow water equivalent, and day length. Workflow is enabled to support the on-demand customization and live feeding to WOFOST modeling. The services enable the parameterization process in WOFOST modeling.

TI Nutrient Leaching When Compost Is Part of Plant Growth Media SO COMPOST SCIENCE & UTILIZATION LA English DT Article ID CHEMICAL-PROPERTIES; URBAN STORMWATER; WATER-QUALITY; BULK-DENSITY; SAND; REMOVAL; SYSTEMS; DESIGN; OPTIMIZATION; PERFORMANCE AB Engineered plant growth media must support plant growth while minimizing environmental impact. The objective of this research was to determine how different growth media influence nutrient leaching. Plant growth media contained varied amounts of soil, sand, compost that did or did not contain manure, and possible sorbents for phosphorus. If the plant growth media included compost derived partly from manure, leaching losses of nutrients were excessive due to the high nutrient load in the compost. Layering compost over the plant media mix resulted in lower nitrate concentrations in effluent (87 mg L-1) compared with mixing compost into the media (343 mg L-1); however, growth of prairie grasses was reduced because of dense media below the compost blanket (0.09 versus 0.31 g). Using lower amounts of compost that did not contain manure resulted in lower mean nitrate concentrations in effluent (101 versus 468 mg L-1). Media that had no soil (13.3 mg L-1) had greater loss of phosphorus after harvest for unsaturated drainage than media with soil (1.8 mg L-1). To reduce nitrate leaching, only small amounts of low-nutrient compost (higher C:N ratio) should be incorporated into the media. If compost is applied as a surface blanket without incorporation, then soil should be added to the sand to reduce density of the media and increase plant growth. C1 [Logsdon, S.

Arnold TI Flag Leaf Photosynthesis and Stomatal Function of Grain Sorghum as Influenced by Changing Photosynthetic Photon Flux Densities SO INTERNATIONAL JOURNAL OF AGRONOMY LA English DT Article ID TEMPERATURE; CROP AB Photosynthesis (A) and stomatal function research in grain sorghum (Sorghum bicolor (L.) Moench) is limited compared to other crops. Flag leaves from three plants of two hybrids, grown with added N-fertilizer of 0.0, 112, and 224 kg ha(-1) near Elizabeth, MS, were measured for A and stomatal functions at growth stages GS6 and GS7. A Li-Cor LI-6400XT set at 355 mu mol [CO2], a flow rate of 500 mu mol s(-1), and a 6400-02 LED light source were used to collect data. Light levels were initially set at 2200 mu mol m(-2) s(-1) indicated photosynthetic photon flux density (PPFD), A was allowed to stabilize, data was recorded, indicated PPFD level was reduced by 200 mu mol m(-2) s(-1), and the process was repeated to a level of 200 mu mol m(-2) s(-1). At GS6 all data were unaffected by N-fertility, hybrids, or years. Data on C-i at GS6 indicated A declines faster with decreasing PPFD than g(s). Intrinsic water use efficiency (IWUE) data supports prior research showing stomata function more to regulate water loss and only marginally limit A. Nitrogen fertility was null on A and stomatal functions and minimal on yield; thus no attempt was made to correlate yield with these data. C1 [Bruns, H.

To determine if recent increases in area burned extend to these higher-elevation landscapes, we analysed wildfires from 1984-2012 in eight mountainous ecoregions of the Pacific Northwest and Northern Rocky Mountains. We considered two components of the alpine treeline ecotone: subalpine parkland, which extends upward from subalpine forest and includes a fine-scale mosaic of forest and non-forested vegetation; and non-forested alpine vegetation. We expected these vegetation types to burn proportionally less than the entire ecoregion, reflecting higher fuel moisture and longer historical fire rotations. In four of eight ecoregions, the proportion of area burned in subalpine parkland (3%-8%) was greater than the proportion of area burned in the entire ecoregion (2%-7%). In contrast, in all but one ecoregion, a small proportion (<= 4%) of the alpine vegetation burned. Area burned regionally was a significant predictor of area burned in subalpine parkland and alpine, suggesting that similar climatic drivers operate at higher and lower elevations or that fire spreads from neighbouring vegetation into the alpine treeline ecotone.

To date, molecular systematics of scale insects has been constrained by the paucity of loci that researchers have been able to amplify with available PCR primers. Due to the rapid molecular evolution of scale insects, "universal" primers, and even primers developed for their sister taxon the Aphidoidea, typically fail. We used transcriptome data for two diaspidids, Acutaspis umbonifera (Newstead) and Chrysomphalus aonidum (Linnaeus), together with a published aphid genome, to design novel PCR primer sets for scale insects. Our primers amplify fragments of eight single-copy genes: ATP-dependent RNA helicase (DHX8), translation initiation factor 5 (IF5X1), DNA replication licensing factor (Mcm2), double-strand break repair protein (MRE I IA), serine/threonineprotein phosphatase (PPP ICB), DNA-directed RNA polymerase II (RNApII), ribonucleoside-diphosphate reductase (RRM I), signal recognition particle receptor (SRP alpha), neuronal PAS domain-containing protein 4 (NPAS4), and cleft lip and palate transmembrane protein 1 (TPI). Here we report the results of tests of amplification success and phylogenetic utility of these primer sets across the Diaspididae and nine other families of Coccomorpha.

The breeding program began in the 1920s with George Darrow and soon thereafter with George Waldo. They utilized the native species, Rubus ursinus, along with 'Logan' in their breeding program to develop the first important commercial cultivars 'Pacific' and 'Cascade' in the 1930s. These two, along with 'Logan, `Santiam, and the R. laciniatus selection 'Evergreen, served as the basis for the trailing blackberry processing industry. Initially fruit was canned and shipped back to the population centers in the eastern US. Freezing to preserve the crop to ship back east became common once the technology for freezing was developed in the 1920s. The breeding programs developed '01allie' in the 1940s that became, along with 'Boysen, the major cultivars in California until the blackberries developed by Driscoll Strawberry Assoc. (Watsonville, CA) surpassed them in area in the early 1990s. In 1956, 'Marion' was released and while it took about 10 years for 'Marion, marketed as marionberry, to become popular, it then became the dominant cultivar in the Pacific northwest. The release of 'Marion' in the 1950s and the development of the machine harvester in the 1960s combined with the ideal climate of the Willamette Valley cemented this region's importance for blackberry production. The industry has been challenged by having 90-95% of production sold for processing. However, even with a small percentage of area devoted to fresh, this region is one of the most important also for fresh fruit in the US. Winters with cold, injurious temperatures have led to large fluctuations in production and grower price, making processors reluctant to develop new products. Thorns in the machine -harvested product also have been a challenge that needed to be overcome. 'Black Diamond, a thornless, high yielding, and more cold hardy cultivar helped increase the reliability of a high quality crop. This stable production combined with increased consumer interest has led to a steadily increased production of fruit for processing as well as for the fresh market. A wonderful climate and a determined industry that has supported collaborative cultivar development and horticultural research have been keys to the development of a vibrant blackberry industry in the Pacific northwest.

The NCGR genebank includes more than 2,035 Rubus accessions, with representatives of 174 Rubus taxa from 57 countries. The primary collection of clonal Rubus and their wild relatives are maintained as plants in containers in greenhouses and screenhouses. The main crops of global economic importance include red raspberries (R. idaeus), the artificial subgenus Idaeobatus, and blackberries, subgenus Rubus, and hybrids between them. Breeders wish to expand gene accessibility outside these subgenera to include representatives of the rich diversity and variability present in the genus. The objective of this research was to evaluate ploidy levels of recently acquired Rubus accessions added to the NCGR collection. Ploidy was assessed through flow cytometry using cell preparations from leaf samples. The base chromosome number for Rubus is x=7. We evaluated Rubus species from seven subgenera. Subgenus Cylactis had a 4x member; subgenus Dalibarda had a diploid member, and subgenus Idaeobatus had 2x, 3x, and 4x types. The blackberry accessions, subgenus Rubus, were the most diverse, having 2x, 4x, 5x, 6x, 7x, 8x, 10x, and 12x cytotypes. Some R. armeniacus samples, introduced from Europe but naturalized in Oregon and California, were 4x; others unexpectedly had much higher ploidy levels. This suggests that R. armeniacus has hybridized with native species of higher ploidy. The two species of Micranthobatus examined were 4x confirming previous chromosome counts, but had very small genomes. Further study of other species in this subgenus is warranted. C1 [Hummer, K.

Microsatellite or simple sequence repeat (SSR) markers are ideal for cultivar fingerprinting, paternity testing and identity certification. The objective of this study was to develop a multiplexed fingerprinting set composed of trinucleotide-containing SSRs and to use them to confirm parentage in breeding populations. Fifteen mapped trinucleotide-containing SSRs were used to screen a test panel of 13 diverse blackberry cultivars from the USDA-ARS National Clonal Germplasm Repository (NCGR) blackberry collection. They were first rated for ease of scoring and polymorphism. The ten SSRs that were polymorphic and easy to score were then evaluated for lack of interaction in multiplex Polymerase Chain Reaction (PCR) after separation of the resulting PCR products by capillary electrophoresis. Each of the SSRs in the resulting two multiplexes generated the same profile in the 13 panel members irrespective of amplification in simplex or multiplex PCR. Both multiplexes differentiated the 13 blackberry cultivars. We plan on evaluating each of these multiplexes for trueness-to-type testing and paternity confirmation of blackberries in the NCGR collection and from eastern and western US breeding populations.

Verticillium dahliae has been isolated from Rubus species showing symptoms of the disease. However, very little is known about the interactions of V. dahliae and woody plants in general, and Rubus in particular. We have compared the root transcriptome sequence data of black raspberry (Rubus occidentalis L.) 'Jewel' inoculated with V. dahliae with that of uninfected 'Jewel' plants grown under greenhouse conditions. From this analysis, 147 genes were found to be differentially expressed (DE). Eight of these genes had apparent homology to known or candidate genes involved in disease resistance. Fourteen genes with homology to transcription factors were among the DE genes. C1 [Bushakra, J.

Recent research about the health benefits of a polyphenolic-rich diet has led to a resurgence of interest and breeding efforts in black raspberry, and is the driving factor for this particular research. Two half-sib populations, ORUS 4304 and ORUS 4305 (307 progeny total) were planted in Jackson Springs, North Carolina in 2012. From fall 2012-spring 2015, a number of traits were measured on each plant, among them vigor, winter hardiness, and heat damage, analyzed in several different ways. Plant vigor increased or decreased over harvest seasons based on individual differences in the segregating plant population, but also showed correlations with temperature, i.e., less vigorous plants were more susceptible to damage by heat or cold. Overall, ORUS 4305 was less vigorous than ORSU 4304. As is the case with most raspberries grown in the southeast, vigor in general is expected to decrease over time; however, certain individuals show transgressive segregation for the trait. Linkage mapping for both populations is underway to identify and validate QTL for vigor, winter hardiness, heat tolerance, and other traits within black raspberry. Ultimately, we hope to gain a more complete understanding of black raspberry physiology and genetics to make breeding commercial quality cultivars a possibility in the southeast. C1 [Bradish, C.

Fruit are most often used for processed products. As a specialty crop, black raspberry production is limited by its susceptibility to viruses, which reduce fruit size and yield and can kill the plant in a few years. As part of a NIFA-SCRI grant project, black raspberry fruit from the same seedling sets were grown at four geographic locations including Oregon, Ohio, New York and North Carolina. The goal of this project is to identify germplasm suitable for expanded processed and fresh market production. Total monomeric anthocyanin and phenolic content, soluble solids content (SSC), and titratable acidity (TA) were determined from fruit harvested in 2013 and 2014 from all sources for 56 seedlings (44 of ORUS 4304 and 12 of ORUS 4305) of two mapping populations. Genotypes were not significantly different in pH, total monomeric anthocyanin, or total phenolic content. Population ORUS 4304 parent ORUS 4158-2 was highest in SSC and grandparent 'Jewel' was highest in titratable acidity. Production environment had a strong effect on fruit composition. Fruit from Oregon-grown seedlings were highest in total monomeric anthocyanin and pH and lowest in titratable acidity. Fruit harvested from North Carolina and Ohio were lowest in total monomeric anthocyanin content.

(Diptera: Drosophilidae), is a recent fruit pest of the Americas whose destructiveness stems from its subcutaneous insertion of eggs into cultivated berries via the female's prominent double bladed and serrated ovipositor. Atypical of most other Drosophila, D. suzukii adults and larvae are non-saprophagous and therefore do not have to contend with fermented substrates containing toxic levels of ethanol. Here, we test whether D. suzukii can safely ingest environmental ethanol, which could have important implications for host selection, reproductive potential, chemical control, and the need for crop sanitation. We designed a series of laboratory experiments to measure critical life history traits of D. suzukii feeding on Rubus and Vaccinium in an ethanolic environment. These life history traits included adult survivorship, sex ratio, and optimal reproductive output. D. suzukii were quite sensitive to ethanol when compared with D. melanogaster. Ethanol concentrations >2.5% reduced both pupal and adult production of SWD and increased adult mortality. Male SWD were 2 to 3 times more sensitive to ethanol than were females with sex ratios increasingly favoring females at higher concentrations. These results suggest that little if any overlap between the niches of SWD and native D. melanogaster will enable these species to coexist. In fact, SWD may create more habitat for wild Drosophila at the expense of both wild and cultivated fruit species. C1 [Sampson, B. J.; Stafne, E. T.; Marshall-Shaw, D. A.; Stringer, S.

Pre- and postharvest fruit diseases also reduce fruit production and quality. A series of trials were conducted in south Mississippi to determine fungicide efficacy for control of rosette, fruit, foliar, and cane diseases. In each trial 8 to 10 fungicides were applied to rosette-susceptible, erect, thorny blackberry cultivars from early leaf emergence through harvest. Fruit were harvested from each plot and assessed within 5 days for postharvest disease symptoms and fruit quality. Foliar and cane diseases were evaluated following harvest. Rosette severity was rated the following spring when symptoms were easily visible. Among the fungicides tested, azoxystrobin, cyprodinil + fludioxonil, and boscalid + pyraclostrobin were the most effective for rosette and postharvest disease control. The results of these trials demonstrated that fungicides are most effective for rosette control when applications began prior to bloom and continue until the fungus has ceased to sporulate. Fungicides effective against rosette also reduced postharvest fruit diseases and leaf and cane rust. C1 [Smith, B.

The development of cultivars with increased resistance to these diseases should result in reduced use of fungicides and greater profits for growers. Five to nine blackberry cultivars adapted to the southeastern USA were evaluated for susceptibility to postharvest fruit diseases and quality in five trials. Fully ripe, blemish-free berries were incubated in the laboratory for four or five days and scored for Botrytis fruit rot, ripe rot, and other fruit diseases on a visual scale: 0 = no disease symptoms to 3 = severe symptoms. Botrytis fruit rot (gray mold) caused by Botrytis cinerea was the most common post-harvest disease identified in these trials while ripe rot caused by Colletotrichum spp. was also important. Across all the studies, 'Navaho', 'Ouachita, and 'Chickasaw' had the fewest berries with postharvest disease symptoms, while 'Shawnee' and 'Arapaho' had the highest Botrytis fruit rot scores. Cultivars with the lowest levels of postharvest fruit diseases received good quality evaluations. Rosette disease occurred on the plants at one location, and rosette disease severity was assessed on the cultivars in that trial. The erect, thorny cultivars, 'Chickasaw', 'Shawnee, and `Kiowa", had significantly more rosettes per plant than the thornless cultivars, 'Sweetie Pie, 'Navaho, and 'Apache'. C1 [Smith, B.

The planting was established in April 2006 at site located in western Oregon, USA. Plants were irrigated by drip or sprinklers and grown with or without N fertilizer. With drip, N was applied by 1) fertigation through the drip system using liquid sources of ammonium nitrate, calcium ammonium nitrate, or urea ammonium nitrate from mid-April to mid-July, 2) split applications of granular calcium nitrate or calcium ammonium nitrate in mid-April and early June, or 3) a single application of granular calcium ammonium nitrate in mid-April followed by fertigation using the three liquid N sources from early June to mid-July. With sprinklers, N was applied at the same time and rate as drip, but only with split applications of the granular fertilizers. The first year, the plants grown without N were chlorotic and had lower leaf N concentrations than those grown with N fertilizer. Leaf N was also lower with sprinklers than with drip but was similar among the fertilized drip treatments, regardless of N source or the application method. Only the drip and sprinkler treatments fertilized with calcium ammonium nitrate were harvested by hand in 2011. As with leaf N, yield was also lower with sprinklers (10.8 t center dot ha(-1)) than with drip (14.6 t center dot ha(-1)) in 2011 and was similar among the drip treatments. All of the treatments were machine harvested the following year. On average, yield continued to be lower with sprinklers (6.1 and 2.5 t center dot ha(-1) with and without N, respectively) than with drip (13.5 and 10.6 t center dot ha(-1) with and without N, respectively) in 2012 but was no longer similar among the fertilized drip treatments. At this point, drip-irrigated plants fertigated with ammonium nitrate or calcium ammonium nitrate had lower yields (7.4 and 11.2 t center dot ha(-1), respectively) than those fertigated with urea ammonium nitrate (14.2 t center dot ha(-1)) or with one or two applications of granular fertilizer (an average of 15.1 t center dot ha(-1)). Overall, the plants produced more yield with drip than with sprinklers but, when irrigated by drip, had the same or lower yields with fertigation than with granular fertilizer. C1 [Bryla, D.

Despite this achievement, virtually none of this genomics knowledge was being used to assist breeding efforts of these crops. Four years later, this gap has been bridged, with genetic information routinely used in many US apple, peach, and cherry breeding programs. For example, DNA tests predict apple crispness, peach maturity date, and cherry fruit size, enabling breeders to determine the best parents to combine and the best seedlings to advance. This application significantly reduces the wasted effort to eliminate entirely poor families and reduces the costs to grow and evaluate thousands of seedlings genetically destined to have unacceptable fruit quality or maturity date. This achievement was enabled by international community efforts, including the RosBREED project, funded by the USDA-National Institute of Food and Agriculture Specialty Crop Research Initiative (SCRI). DNA tests are now applied for high-value attributes where the targeted loci explain a large proportion of the trait variation. However, limitations to widespread adoption of these predictive tests still exist. Some limitations are due to lack of knowledge, such as an understanding of genotype by environment (GxE) interactions and loci associated with variation for other valuable attributes. Technical limitations include streamlined phasing of alleles from multiple families of pedigree-connected breeding germplasm and access to suitable commercial service providers.

Recent research about the health benefits of a diet rich in polyphenolics, from black raspberries in particular, has led to a resurgence of interest in this fruit and a renewal of breeding efforts. This study seeks to advance and streamline identification of a variety of traits of interest to growers and consumers in black raspberry germplasm through phenotyping and socio-economic analyses. The information will be integrated into breeding programs with the goal of developing disease resistant cultivars that satisfy the demands of the marketplace, adding to the sustainability and profitability of the industry. Two related full-sib populations, designated ORUS 4304 (192 progeny) and ORUS 4305 (115 progeny), were planted across the production regions. Primocane (non-fruiting canes) vigor was rated from 1 (dead) to 9 (very vigorous) at each site. Initial analysis of genotype by environment (GxE) influences on primocane vigor indicated that overall the populations showed no significant difference in vigor in different environments; however, individual genotypes showed significant variation depending on site conditions. Vigor data will be compared with the genetic linkage map to determine which genomic regions contribute to the control of this complex trait. The genomic tools we are developing will be applied to the identification of quantitative trait loci (QTL) and alleles important for breeding objectives regionally and nationally. C1 [Bushakra, J.

A new virus, closely associated with the disease has been recently identified. The virus, tentatively named Blueberry mosaic associated virus (BlMaV), is a putative member of the genus Ophiovirus with a genome comprised of three negative-sense RNAs (RNAs 1-3). Genome organization and phylogenetic analysis indicates that BlMaV resembles Citrus psorosis virus, the type member of the family Ophioviridae. RNA 1 encodes two proteins, a 23 kDa protein of unknown function and a 272 kDa replicase. RNAs 2 and 3 encode for a putative 58 kDa movement protein and the 50 kDa nucleocapsid protein, respectively. Phylogenetic analyses conducted on 1200 nucleotides of coding regions in RNAs 2 and 3 of 59 North American and European isolates revealed significant amino acid conservation among isolates.

To help growers target these markets, long-term organic systems trials were established at Oregon State University's North Willamette Research and Extension Center (Aurora, OR, USA) for blueberry in 2006 and for blackberry in 2010. Each planting is 0.4 ha and was certified organic (Oregon Tilth) prior to the first fruit harvest. Both trials are based on industry-driven priorities and were designed through communication with an advisory group consisting of organic and conventional growers, wholesale fruit packers, and research and extension faculty. Initial challenges included finding economical weed and nutrient management tools and adapted cultivars of both crops. Cumulative yield with various production systems ranged from 21 to 60 t ha(-1) in blueberry (2008-2013) and 13 to 26 t ha(-1) in blackberry (2012-2013). Successful outcomes include information on differences between cultivars in ease of management in organic production; sensitivity of blueberry to high N fertilizer rates (also a problem in conventional systems); benefits of compost to blueberry nutrient management; impacts of weeds on blackberry yield; establishing plantings using drip irrigation and fertigation with fish emulsion; and the successful use of weed mat to increase yield compared to sawdust mulch in blueberry and hand-weeding in blackberry. Growers now have better management options for organic fertilization and weed management, and many have shifted to using weed mat mulch in organic and conventional plantings and are fertigating more economically with fish emulsion.

Plant growth response of diverse pear genotypes on standard tissue culture medium varies widely. A group of studies were designed to determine the mineral nutrient requirements for micropropagation of pear shoots from this diverse collection. Initially, five mineral nutrient factors were created from MS salts- NH4NO3, KNO3, mesos components (CaMg-Cl-Mn-SO4-PO4), metals (Zn-Mn-Cu-Co-Mo-B-I), and Fe-EDTA. Each factor was varied over a range of concentrations. Treatment combinations were selected using response surface methodology (RSM). Five pear genotypes in three species (Pyrus communis, P, dimorphophylla and P ussuriensis) were grown on each treatment combination. Measurements included shoot quality, severity of leaf spotting/necrosis, leaf size, shoot number, and shoot length, and each response was analyzed by ANOVA with results modeled using RSM. Models for each genotype identified the factors with the largest growth responses. Additional experiments, testing mesos and nitrogen components, determined the optimal concentrations of these factors for a wider range of pear species and cultivars. Mineral nutrient formulations were identified that resulted in significantly better growth for all the genotypes tested. This approach was very successful for defining new media for shoot proliferation of diverse pear germplasm. C1 [Reed, B. M.; DeNomal, J.] USDA ARS NCGR, 33447 Peoria Rd, Corvallis, OR 97333 USA.

Field collections, potted plants, or in some cases whole plants stored under cool to cold conditions are complemented by in vitro culture, in vitro storage, and cryopreservation. The use of complementary storage techniques is important for successful germplasm preservation and in vitro storage is one important technique for germplasm in an active genebank. In vitro cultures of temperate plants are routinely stored at-1 to 5 degrees C for as long as 4 years without subculture. Sub-tropical and tropical plants can be held at sub-normal temperatures (15-18 degrees C) for long periods as well. This storage form is important for active collections and provides a readily accessible form of germplasm for distribution to the user community. Medium-term storage is highly successful for Pyrus germplasm for a wide range of species and cultivars. Many factors influence the duration of cold storage for pears and other temperate crops. The most important factor is to store healthy disease-free shoots that are growing well in culture. Healthy plants on the correct multiplication and storage media, stored in the correct container by a skilled technician will remain in 4 C storage for 2 to 4 years and greatly reduce the labor and materials needed to maintain an in vitro germplasm collection.

This study compared shoot initiation techniques for apples. Shoots were forced from dormant bud wood in the laboratory or directly taken from the field as new growth in the spring. Fourteen promising apple cultivars, five clonal rootstocks (Malus x domestica Borkh.) and 10 wild Malus sieversii (Ledeb. M. Roem.) were introduced into culture. All shoots were treated with 0.1% HgCl2 for 10 min. Cultures were initiated on liquid Murashige and Skoog medium containing 30 g L-1 of sucrose, 0.5 mg L-1 of 6-benzylaminopurine, 0.01 mg L-1 of indole-3-butyric acid, 1 mg L-1 of gibberellic acid and 1 mg L-1 of L ascorbic acid, pH 5.7, for 2-4 weeks with daily transfers to fresh medium, and then moved to solid MS medium for propagation. Cultures were indexed for bacteria and fungi using the 523 detection medium and any infected shoots were discarded. Shoot initiation from forced dormant vegetative buds varied from 22.3 to 82.3% with a mean of 55.0% for the 35 genotypes. Shoots, collected from new growth under field conditions, initiated clean shoots with a range from 5.1 to 44.8% and a mean of 18.4% for all genotypes. Shoot cultures were established from all of the tested genotypes. Many of these genotypes had never been cultured before, so this study is strategic for the security of important Malus germplasm. These shoot cultures will be used for the creation of Kazakhstan's apple cryobank. C1 [Romadanova, N. V.; Mishustina, S. A.; Matakova, G. N.; Kushnarenko, S. V.; Rakhimbaev, I.

Transgenic line 55-1 and derived progeny 'SunUp' and 'Rainbow' are resistant to PRSV and have saved the papaya industry in Hawaii. In small scale replicated field plots we were able to protect susceptible Caricaceae germplasm using PRSV resistant transgenic papayas as border plantings in the presence of both the aphid vector and PRSV-infected plants. Currently we are testing this concept in commercial field sites by combining aphid vector monitoring and early detection of PRSV with the hopes that this may serve as a model for coexistence of conventional and genetically modified crops.

We report here our identification of thousands of unambiguous molecular markers that can be easily assayed across genotypes of the species. With origin centered in Southeast Asia, mangos are grown throughout the tropics and subtropics as a nutritious fruit that exhibits remarkable intraspecific phenotypic diversity. With the goal of building a high density genetic map, we have undertaken discovery of sequence variation in expressed genes across a broad range of mango cultivars. A transcriptome sequence reference was built de novo from extensive sequencing and assembly of RNA from cultivar 'Tommy Atkins'. Single nucleotide polymorphisms (SNPs) in protein coding transcripts were determined from alignment of RNA reads from 24 mango cultivars of diverse origins: 'Amin Abrahimpur' (India), 'Aroemanis' (Indonesia), 'Burma' (Burma), 'CAC' (Hawaii), 'Duncan' (Florida), 'Edward' (Florida), 'Everbearing' (Florida), 'Gary' (Florida), 'Hodson' (Florida), 'Itamaraca' (Brazil), 'Jakarata' (Florida), 'Long' (Jamaica), 'M. Casturi Purple' (Borneo), 'Malindi' (Kenya), 'Mulgoba' (India), 'Neelum' (India), 'Peach' (unknown), 'Prieto' (Cuba), 'Sandersha' (India), 'Tete Nene' (Puerto Rico), 'Thai Everbearing' (Thailand), 'Toledo' (Cuba), 'Tommy Atkins' (Florida) and 'Turpentine' (West Indies). SNPs in a selected subset of protein coding transcripts are currently being converted into Fluidigm assays for genotyping of mapping populations and germplasm collections. Using an alternate approach, SNPs (144) discovered by sequencing of candidate genes in 'Kensington Pride' have already been converted and used for genotyping. C1 [Kuhn, D.

Removed orchards are typically either pushed out and burned or ground up and removed. Stored carbon is lost from the orchard site. Woody debris incorporated into soils could increase organic matter, enhance carbon sequestration, and improve soil quality and tree yield. The objective of this project was to compare the grinding up of whole trees with burning as a means of orchard removal. Twenty-two rows of an experimental orchard were used in a randomized blocked experiment with two main treatments, whole tree grinding and incorporation into the soil versus tree pushing and burning. The whole tree grinding did not stunt replanted tree growth. Sampling from plots showed elevated levels of fungal and bacterial feeding nematodes (Tylenchidae) along with associated woody soil aggregates in the grind treatment. Fungal mycelium was readily observed colonizing woody aggregates and significantly more basidiomycetes (mushrooms) were observed in the grind plots. No difference in yield was observed in 2011, however, in 2012 and 2013 (P=0.08) greater yields were observed in the grind treatment when compared to the burn. In 2010, more carbon, organic matter, and a greater cation exchange capacity were initially observed in the burned plots, but by 2012 and 2013 the grind plots had significantly more calcium, manganese, iron, magnesium, boron, nitrate, copper, as well as higher electrical conductivity, organic matter, total carbon, and organic carbon. Soil pH was significantly lower in the grind treatment plots. Leaf petiole analysis in 2013 showed significantly greater levels of nitrogen, potassium, phosphorus, manganese, and iron from trees growing in the grind treatment, while magnesium and sodium levels were significantly less.

One strategy to improve cherry resistance to phytoplasma involves transgenic expression of disease-resistant gene in phloem. To achieve efficient phloem-specific expression in cherry, we constructed a binary vector with expression cassettes harboring the beta-glucuronidase (GUS) reporter gene under control of the Arabidopsis sucrose-H+ symporter gene (AtSUC2) promoter. Eleven transgenic cherry lines were obtained from 500 leaf explants of 'Gisela 6'. The integration of GUS gene into cherry genome was confirmed by PCR and southern blot analysis. Histological GUS activity indicated that the reporter gene was expressed specifically in phloem of leaves veins, petioles, stems of transgenic cherry plants. Results suggest that the AtSUC2 promoter may be useful for engineering phytoplasma-resistant transgenic cherries.

A reference gene with a low variance in its expression for one set of samples may not be suitable for other experiments sampled across different developmental stages, tissue types and seasons. The latter are often typical of postharvest gene expression experiments. In this study we initially used 61 mRNA-seq data sets from different tissues, stages of development and stress conditions of apple (Malus x domestica) to select 10 potential reference genes. These were tested using RT-qPCR, reference gene selection software, and 156 mRNA-seq datasets from a second independent laboratory. From these results we have selected four potential reference genes for use in postharvest and other apple gene expression experiments. Use of this mRNA-seq data method may facilitate selection of reference genes in other crop species for which these data are available. C1 [Bowen, J. H.; Schaffer, R. J.; Johnston, J. W.; Ireland, H.

MQD threatens commercial and residential production of macadamia (Macadamia integrifolia) in Hawaii. To identify strategies to manage the disease and prolong macadamia production, fungicide and application measures were evaluated. Fosphite r was examined in vitro and inhibited radial growth of Phytophthora tropicalis on fungicide-amended 10% V8 juice agar. A leaf bioassay method was developed to test for age effect, cultivar susceptibility and in vitro disease suppression. Results indicated that cultivar, leaf age and location of inoculation affected lesion size. In vitro applications of Fosphite (R) reduced lesion sizes by similar to 70%. In field studies, a soil drench application of Fosphite (R) was compared with passive and active injection methods. Results indicate that drenches and/ or tree injections with phosphorous acid fungicides can arrest the progression of the MQD symptoms in infected trees, eliminate visible symptoms and prolong their productive life, in some instances for as much as 1000 additional days.

TI Modeling duration of FSA operating and farm ownership loan guarantees SO AGRICULTURAL FINANCE REVIEW LA English DT Article DE Agricultural credit; Competing risks; Cox proportional hazards; Farm service agency; Guaranteed loan AB Purpose - The purpose of this paper is to identify determinants of feasible outcome events (expired with no loss, settled for loss, still performing) and time to event of Farm Service Agency (FSA) operating and farm ownership (FO) loan guarantees. Design/methodology/approach - Data on 19,126 FSA guaranteed loans, which were made by various lenders to farmers who have limited ability to obtain loans from normal sources without the Federal guarantee, were collected. Cox proportional hazards models for operating loans (OLs) and FO loans are estimated to identify borrower characteristics, loan characteristics, lender types, and farm and macroeconomic environment factors that influence guarantee outcomes. Findings - Loans with different characteristics (loan amount, loan term, lender type, region originated) and assistance programs (Beginning Farmer, Interest Assistance) have differing guarantee outcomes. Contemporaneous variables, in particular delinquency status, have a significant impact on guarantee outcomes. Research limitations/implications - All loans were originated in calendar years 2004 and 2005. Since FO loans may have as long as 40 year terms, results are not as robust for FO loans as for OLs. Practical implications - Different loan characteristics and macroeconomic conditions significantly influence the occurrence of possible guarantee outcomes and time to the outcomes. Originality/value - Guaranteed loans are the primary method of government credit assistance to US farm operators. Data on individual borrowers have been difficult to obtain for much of the life of the guaranteed program because loan applications are held privately. This study provides insight on how various factors drive guarantee performance which is useful to policy makers trying to increase guaranteed loan program efficiency.

The analysis will identify factors that significantly influence both the probability of FSA borrowers' survival (capability to remain in good credit standing) and temporal endurance (or length of period of good standing with creditor). Design/methodology/approach - This analysis utilizes a data set of farm borrowers of the Farm Service Agency that regular farm lenders have classified as "marginal" relative to other borrowers. The research goal is addressed by confining this study's regional focus to the Southeast and Midwest that have both dealt with financial stress arising from abnormal natural and economic conditions prevailing during the same time period. A split population duration model is employed to separately identify determinants of the probability and duration of survival (condition of good credit standing). Findings - This study's results indicate that larger loan balances, declining commodity prices, and the severity of drought conditions have adversely affected both the borrowing farms' probability of survival and temporal endurance in terms of maintaining non-delinquent borrower standing. Notably, Midwestern farms have been relatively less affected by drought conditions compared to Southeastern farms. This study's results validate the contention that the farms' capability to survive and the duration of their survival can be attributed to differences in regional resource endowments, farming activities, and business structures. Originality/value - This study's analytical framework departs from the basic duration model approach by considering temporal endurance, in addition to survival probability analysis. This study's original contributions are enhanced by its specific focus on the contrasting farm business structures and operating environments in the Midwest and Southeast regions.

To examine this in geologically young soils in the northern Great Plains of North America, we present near-surface (0-7.6 cm) soil chemistry data from 16 years of two crop rotations: continuous crop (CC; spring wheat [Triticum aestivum L.]-winter wheat [T. aestivum]-sunflower [Helianthus annuus L.]) and crop-fallow (C-F; spring wheat-fallow) that underwent factorial tillage (none, minimum, conventional) and N rate (low, medium, high) treatments. For CC, the N rate (but not tillage) had a significant effect on pH, with the high N rate leading to the largest pH decline (-0.76). The nitrogen rate also had a significant effect on cation exchange capacity (CEC) for CC, whereby CEC increased with the N rate. Managers utilizing high N rates should be aware of the potential for soil acidification, even in the northern Great Plains of North America.

The study was conducted on Pawnee soil, a major U.S. benchmark soil in the Great Plains. The objectives were to investigate the effects of four common land uses [NoTill (NT), Conventional Till (CT), Grass (G), and Conservation Reserve Program (CRP)] on: i) selected soil properties [total organic carbon (TOC), bulk density (BD), pH, cation exchange capacity (CEC), and electric conductivity (EC)] and ii) water-soluble concentration of 14 heavy metals and micronutrients. The analysis of variance (ANOVA test) indicated that the land use had significant effects on the TOC, CEC, and EC, whereas no relation was detected for BD and pH. Irrespective of land use, the mean element concentration in soil could be arranged in the order: Si (Silicon) > Al (Aluminum) > Fe (Iron) > Mn (Manganese) > B (Boron) > Zn (Zinc) > Cr (Chromium) > Ni (Nickel) > Cu (Copper) > As (Arsenic) > Pb (Lead) > Co (Cobalt) > Mo (Molybdenum) > Cd (Cadmium). Silicon, Al, and Fe which are usually form the major components of soil minerals were present in much higher levels (91 to 308mg/kg) than other elements in soil. Essential plant micronutrients such as B, Cu, Mn, Mo, and Zn, generally presented moderate levels in soil (7 to 698 mu g/kg), whereas toxic heavy metals such as As, Cd, Co, Ni, and Pb were present in the lowest values (0.7-96.2 mu g/kg). The ANOVA test indicated land use had significant effects on As, B, Cd, Co, Cu, Ni, and Si concentration in soil while effects were insignificant for other elements. The data proved the important effects of land use on dynamic soil properties as well as nutrient and heavy metal for a major benchmark soil. Thus, more studies on other major soils are warranted. The information is needed to modify and adapt management practices to improve and sustain soil health and water quality in the US Great Plains.

Accurate Evapotranspiration (ET) observations and estimations are crucial in water cycle studies to estimate water losses from the terrestrial surfaces to the atmosphere to close the regional water budget. The eddy covariance (EC) method is an important technique measure ET and other land surface energy fluxes. However, the underestimation of energy fluxes and the problem of EC energy balance non-closure are far from solved. In this study, a new method is proposed to account for advection in order to correct EC data under advective environments. This advection based method was applied to data from Bushland, TX, which is subject to dry air and strong winds. Observations from two identical EC systems as well as two precision monolithic weighing lysimeters were used in this analysis. Both EC sites showed significant underestimates of evapotranspiration (ET) compared with lysimeter measurements. The daily energy balance closure for NE01 and SE02 sites were 0.78 and 0.74 respectively. The advection correction method provided improved performance in daytime, and it is more suitable for ET estimate than forcing closure under the advective environment. For nighttime, two methods (NCM1 and NCM2) were proposed to correct EC underestimates. Finally, all the corrected. ET values were compared with the lysimeter measurements. For NE01 site, the MAD (mean absolute deviation) and the RMSD (root mean square deviation) were 47.72 W/m(2) and 67.66 W/m(2), respectively; and the r(2) (coefficient of determination) was 0.85. For SE02 site, the MAD and RMSD were 30.59 W/m(2) and 44.43 W/m(2); and the r(2) was 0.93. The statistical' measures illustrated that the proposed methods are functional and appropriate' under an advective environment. The accurate estimate of actual evapotranspiration will benefit both the strategic planning of optimal water uses and the improved understanding the environmental and hydrological processes.

K-sat is infamous for its spatial and temporal variability, which contributes to the difficulty and considerable expense in measuring or otherwise quantifying it. Consequently, predictive methods such as pedotransfer functions (PTFs) that use physical soil properties, such as texture and bulk density, have been developed to derive K-sat values. Soil texture and structure are key factors influencing K-sat because of their direct relationship to pore size distribution. Quantitatively defining the combined effects of texture and structure on pore size distribution in a PTF is a difficult task. The objectives of this research were to: (i) estimate K-sat based on pore characteristics derived from soil thin sections via image analysis; and (ii) compare the resultant values with field-measured K-sat and with K-sat estimated by a PTF using soil texture and bulk density parameters. We digitally scanned 39 thin sections from 11 pedons of soils derived from loess over till and/or over weathered sandstone. Soil voids were classified based on their size and shape. K-sat was measured in the field using a Compact Constant-head Permeameter (Amoozemeter) and estimated using a Rosetta PTF. Simple and multiple linear regression (MLR) analyses were used to relate pore indexes and soil physical properties with measured and estimated K-sat. The mean measured K-sat was 0.74 cm h(-1), whereas the PTF-estimated K-sat from Rosetta and MLR were 0.36 cm h(-1) and 0.49 cm h(-1), respectively. The addition of pore characteristics into the model improved K-sat predictions compared to predictions using Rosetta alone. The estimated K-sat based on the model with added pore characteristics was better correlated with field-measured K-sat (r = 0.82) than that based on Rosetta (r = 0.62). The addition of pore characteristics can improve K-sat predictions. However, thin section void analysis from additional parent materials is needed.

While aggregated soil properties are readily estimated via standard statistical functions (mean, median, etc.), an aggregated representation of horizonation (e.g., genetic or functional horizon designation and depth) is typically difficult to construct. Variation in horizon designation use among soil scientists and different soil description systems, changes in horizon designation standards over time, variable depths at which horizons occur, and the uncertainties associated with these are all factors that complicate the process of delivering an aggregated representation of horizonation. In this chapter, we propose alternatives to the typical "representative profile,"e.g., the selection of a single soil profile to represent a collection. Two possible methods for aggregating a collection of soil profiles into synthetic profiles are presented, describing depth-wise probability functions for each horizon. Both methods rely on an expert-guided description of generalized horizon designation (e.g., a subset of horizon designation labels that convey a reasonable "morphologic story") along with associated rules (regular expression patterns) used to correlate field-described to generalized horizon designation. The first method is based on (1-cm interval) slice-wise evaluation of generalized horizon designation; the second is based on a proportional-odds logistic regression model fit to depth-slices. These methods are demonstrated using USDA-NRCS soil survey data (USA). C1 [Beaudette, D. E.] USDA, NRCS, Sonora, CA 95370 USA. [Roudier, P.] Landcare Res, Lincoln, NE, New Zealand.

The data contained in each of these grid cells are data rich in nature and include probability and uncertainty information that allow the modeling of the soil continuum. The same advances in computer technology and digital information are now being applied to data capture for pedon descriptions.
