We characterized mechanisms of drought resistance in early and late-successional species and tested whether risk of drought differs across sites at different successional stages, and whether early and late-successional species differ in resistance to experimentally imposed soil drought. The microenvironment in early successional sites was warmer and drier than in mature forest. Nevertheless, successional groups did not differ in resistance to soil drought. Late-successional species resisted drought through two independent mechanisms: high resistance of xylem to embolism, or reliance on high stem water storage capacity. High sapwood water reserves delayed the effects of soil drying by transiently decoupling plant and soil water status. Resistance to soil drought resulted from the interplay between variations in xylem vulnerability to embolism, reliance on sapwood water reserves and leaf area reduction, leading to a tradeoff of avoidance against tolerance of soil drought, along which successional groups were not differentiated. Overall, our data suggest that ranking species' performance under soil drought based solely on xylem resistance to embolism may be misleading, especially for species with high sapwood water storage capacity.

A custom phenotyping platform was designed to capture images of whole root systems, and novel software tools were developed to process and analyse these images. The platform and its components are adaptable to a wide range root phenotyping studies using diverse growth systems (hydroponics, paper pouches, gel and soil) involving several plant species, including, but not limited to, rice, maize, sorghum, tomato and Arabidopsis. The RootReader2D software tool is free and publicly available and was designed with both user-guided and automated features that increase flexibility and enhance efficiency when measuring root growth traits from specific roots or entire root systems during large-scale phenotyping studies. To demonstrate the unique capabilities and high-throughput capacity of this phenotyping platform for studying root systems, genome-wide association studies on rice (Oryza sativa) and maize (Zea mays) root growth were performed and root traits related to aluminium (Al) tolerance were analysed on the parents of the maize nested association mapping (NAM) population.

TI An RNA-Seq Transcriptome Analysis of Orthophosphate-Deficient White Lupin Reveals Novel Insights into Phosphorus Acclimation in Plants SO PLANT PHYSIOLOGY LA English DT Article ID PHOSPHATE STARVATION RESPONSES; GENOME-WIDE IDENTIFICATION; CLUSTER ROOT ACCLIMATION; INDUCED GENE-EXPRESSION; E3 LIGASE SIZ1; PROTEOID ROOTS; ALBUS L.; ARABIDOPSIS-THALIANA; IRON HOMEOSTASIS; PHASEOLUS-VULGARIS AB Phosphorus, in its orthophosphate form (P-i), is one of the most limiting macronutrients in soils for plant growth and development. However, the whole-genome molecular mechanisms contributing to plant acclimation to P-i deficiency remain largely unknown. White lupin (Lupinus albus) has evolved unique adaptations for growth in P-i-deficient soils, including the development of cluster roots to increase root surface area. In this study, we utilized RNA-Seq technology to assess global gene expression in white lupin cluster roots, normal roots, and leaves in response to P-i supply. We de novo assembled 277,224,180 Illumina reads from 12 complementary DNA libraries to build what is to our knowledge the first white lupin gene index (LAGI 1.0). This index contains 125,821 unique sequences with an average length of 1,155 bp. Of these sequences, 50,734 were transcriptionally active (reads per kilobase per million reads >= 3), representing approximately 7.8% of the white lupin genome, using the predicted genome size of Lupinus angustifolius as a reference. We identified a total of 2,128 sequences differentially expressed in response to P-i deficiency with a 2-fold or greater change and P <= 0.05. Twelve sequences were consistently differentially expressed due to P-i deficiency stress in three species, Arabidopsis (Arabidopsis thaliana), potato (Solanum tuberosum), and white lupin, making them ideal candidates to monitor the P-i status of plants. Additionally, classic physiological experiments were coupled with RNA-Seq data to examine the role of cytokinin and gibberellic acid in P-i deficiency-induced cluster root development. This global gene expression analysis provides new insights into the biochemical and molecular mechanisms involved in the acclimation to P-i deficiency. C1 [O'Rourke, Jamie A.; Yang, S.

LEAVES; NORNICOTINE CONVERSION; ETHYLENE BIOSYNTHESIS; SACCHAROMYCES-CEREVISIAE; LEAF SENESCENCE; HIGHER-PLANTS; EXPRESSION; GENE AB Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme of the tetrahydrofolate (THF)-mediated one-carbon (C1) metabolic network. This enzyme catalyzes the reduction of 5,10-methylene-THF to 5-methyl-THF. The latter donates its methyl group to homocysteine, forming methionine, which is then used for the synthesis of S-adenosyl-methionine, a universal methyl donor for numerous methylation reactions, to produce primary and secondary metabolites. Here, we demonstrate that manipulating tobacco (Nicotiana tabacum) MTHFR gene (NtMTHFR1) expression dramatically alters the alkaloid profile in transgenic tobacco plants by negatively regulating the expression of a secondary metabolic pathway nicotine N-demethylase gene, CYP82E4. Quantitative real-time polymerase chain reaction and alkaloid analyses revealed that reducing NtMTHFR expression by RNA interference dramatically induced CYP82E4 expression, resulting in higher nicotine-to-nornicotine conversion rates. Conversely, overexpressing NtMTHFR1 suppressed CYP82E4 expression, leading to lower nicotine-to-nornicotine conversion rates. However, the reduced expression of NtMTHFR did not affect the methionine and S-adenosyl-methionine levels in the knockdown lines. Our finding reveals a new regulatory role of NtMTHFR1 in nicotine N-demethylation and suggests that the negative regulation of CYP82E4 expression may serve to recruit methyl groups from nicotine into the C1 pool under C1-deficient conditions.

We performed comparative microarray analysis on maize whorl and root tissues from the insect resistant inbred Mp708 in response to foliar feeding by fall armyworm (Spodoptera frugiperda) caterpillars. Although Mp708 has elevated jasmonic acid (JA) levels prior to herbivory, genes involved in JA biosynthesis were up-regulated in whorls in response to fall armyworm feeding. Alternatively, genes possibly involved in regulating ethylene (ET) perception and signaling were up-regulated in roots following foliar herbivory. Transcript levels of genes encoding proteins involved in direct defenses against herbivores were enhanced both in roots and leaves, but transcriptional factors and genes involved in various biosynthetic pathways were selectively down-regulated in the whorl. The results indicate that foliar herbivory by fall armyworm changes root gene expression pathways suggesting profound long distance signaling. Tissue specific induction and suppression of JA and ET signaling pathway genes provides a clue to their possible roles in signaling between the two distant tissue types that eventually triggers defense responses in the roots in response to foliar herbivory.

The etiology of the disease has been debated since its initial discovery, and at various times lungworms, Mannheimia haemolytica and other Pasteurellaceae, and Mycoplasma ovipneumoniae have been proposed as primary causal agents. A multi-factorial "respiratory disease complex" has also been proposed as confirmation of causation has eluded investigators. In this paper we review the evidence for each of the candidate primary agents with regard to causal criteria including strength of association, temporality, plausibility, experimental evidence, and analogy. While we find some degree of biological plausibility for all agents and strong experimental evidence for M. haemolytica, we demonstrate that of the alternatives considered, M. ovipneumoniae is the best supported by all criteria and is therefore the most parsimonious explanation for the disease. The strong but somewhat controversial experimental evidence implicating disease transmission from domestic sheep is consistent with this finding. Based on epidemiologic and microbiologic data, we propose that healthy bighorn sheep populations are naive to M. ovipneumoniae, and that its introduction to susceptible bighorn sheep populations results in epizootic polymicrobial bacterial pneumonia often followed by chronic infection in recovered adults. If this hypothesized model is correct, efforts to control this disease by development or application of vectored vaccines to Pasteurellaceae are unlikely to provide significant benefits, whereas efforts to ensure segregation of healthy bighorn sheep populations from M. ovipneumoniae-infected reservoir hosts are crucial to prevention of new disease epizootics. It may also be possible to develop M. ovipneumoniae vaccines or other management strategies that could reduce the impact of this devastating disease in bighorn sheep. (c) 2012 Elsevier B.V.

Fifty-six percent of all colonies monitored during the 10-month period died. The relative risk (RR) that a colony would die over the short term (similar to 50 days) was appreciably increased in colonies diagnosed with Idiopathic Brood Disease Syndrome (IBDS), a condition where brood of different ages appear molten on the bottom of cells (RR = 3.2), or with a "queen event" (e.g., evidence of queen replacement or failure; RR = 3.1). We also found that several risk factors-including the incidence of a poor brood pattern, chalkbood (CB), deformed wing virus (DWV), sacbrood virus (SBV), and exceeding the threshold of 5 Varroa mites per 100 bees-were differentially expressed in different beekeeping operations. Further, we found that a diagnosis of several factors were significantly more or less likely to be associated with a simultaneous diagnosis of another risk factor. These finding support the growing consensus that the causes of colony mortality are multiple and interrelated. (c) 2012 Elsevier B.V. All rights reserved.

In the National Animal Health Monitoring System's (NAHMS) Dairy 2007 study, the apparent herd-level prevalence of MAP was 70.4% (369/524 had >= 1 culture-positive composite fecal samples out of 6 tested). Based on these data, the true herd-level prevalence (HP) of MAP infection was estimated using Bayesian methods adjusting for the herd sensitivity (HSe) and herd specificity (HSp) of the test method. The Bayesian prior for HSe of composite fecal cultures was based on data from the NAHMS Dairy 2002 study and the prior for HSp was based on expert opinion. The posterior median HP (base model) was 91.1% (95% probability interval, 81.6 to 99.3%) and estimates were most sensitive to the prior for HSe. The HP was higher than estimated from the NAHMS Dairy 1996 and 2002 studies but estimates are not directly comparable with those of prior NAHMS studies because of the different testing methods and criteria used for herd classification.

TI Gut Microbiomes of Malawian Twin Pairs Discordant for Kwashiorkor SO SCIENCE LA English DT Article ID SERUM AMINO ACIDS; LACTOBACILLUS-GASSERI; CHILDREN; FOOD; MALNUTRITION; FERMENTATION; BACTERIA; PLASMA; STOOL; URINE AB Kwashiorkor, an enigmatic form of severe acute malnutrition, is the consequence of inadequate nutrient intake plus additional environmental insults. To investigate the role of the gut microbiome, we studied 317 Malawian twin pairs during the first 3 years of life. During this time, half of the twin pairs remained well nourished, whereas 43% became discordant, and 7% manifested concordance for acute malnutrition. Both children in twin pairs discordant for kwashiorkor were treated with a peanut-based, ready-to-use therapeutic food (RUTF). Time-series metagenomic studies revealed that RUTF produced a transient maturation of metabolic functions in kwashiorkor gut microbiomes that regressed when administration of RUTF was stopped. Previously frozen fecal communities from several discordant pairs were each transplanted into gnotobiotic mice. The combination of Malawian diet and kwashiorkor microbiome produced marked weight loss in recipient mice, accompanied by perturbations in amino acid, carbohydrate, and intermediary metabolism that were only transiently ameliorated with RUTF. These findings implicate the gut microbiome as a causal factor in kwashiorkor.

The full-fat (FF), reduced-fat (RF), low-fat (LF), and non-fat (NF) cheeses contained 48.7, 50.0, 51.5 and 55.2% moisture and 26.3, 19.0, 9.65, and 1.50% fat, respectively. Although the amount of protein in the cheese increased as fat was reduced, the FF, RF, and LF cheeses had 40-44% degradation of beta-casein over the 6 mo of the study while minimal proteolysis (14%) occurred in the NF cheese. The NF cheese exhibited the highest hardness, cohesiveness, chewiness, elastic modulus, viscous modulus, and complex viscosity values due to the denser protein matrix. The FF and RF cheeses had similar rheological values. The fat content of high-moisture Cheddar-like goat cheese can be lowered to 19% without affecting its texture. Published by Elsevier B.V.

TI Molecular mapping of vernalization requirement and fertility restoration genes in carrot SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID CYTOPLASMIC MALE-STERILITY; DAUCUS-CAROTA-L.; FLOWERING-TIME GENES; LINKAGE GROUPS; ARABIDOPSIS-THALIANA; F-2 POPULATIONS; BRASSICA-NAPUS; MARKERS; LOCUS; AFLP AB Carrot (Daucus carota L.) is a cool-season vegetable normally classified as a biennial species, requiring vernalization to induce flowering. Nevertheless, some cultivars adapted to warmer climates require less vernalization and can be classified as annual. Most modern carrot cultivars are hybrids which rely upon cytoplasmic male-sterility for commercial production. One major gene controlling floral initiation and several genes restoring male fertility have been reported but none have been mapped. The objective of the present work was to develop the first linkage map of carrot locating the genomic regions that control vernalization response and fertility restoration. Using an F-2 progeny, derived from the intercross between the annual cultivar 'Criolla INTA' and a petaloid male sterile biennial carrot evaluated over 2 years, both early flowering habit, which we name Vrn1, and restoration of petaloid cytoplasmic male sterility, which we name Rf1, were found to be dominant traits conditioned by single genes. On a map of 355 markers covering all 9 chromosomes with a total map length of 669 cM and an average marker-to-marker distance of 1.88 cM, Vrn1 mapped to chromosome 2 with flanking markers at 0.70 and 0.46 cM, and Rf1 mapped to chromosome 9 with flanking markers at 4.38 and 1.12 cM. These are the first two reproductive traits mapped in the carrot genome, and their map location and flanking markers provide valuable tools for studying traits important for carrot domestication and reproductive biology, as well as facilitating carrot breeding.

TI Molecular mapping of Yr53, a new gene for stripe rust resistance in durum wheat accession PI 480148 and its transfer to common wheat SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID F-SP TRITICI; ANALOG POLYMORPHISM MARKERS; PUCCINIA-STRIIFORMIS; UNITED-STATES; BREAD WHEAT; AESTIVUM L.; RACES; TURGIDUM; IDENTIFICATION; CULTIVARS AB Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most damaging diseases of wheat worldwide. It is essential to identify new genes for effective resistance against the disease. Durum wheat PI 480148, originally from Ethiopia, was resistant in all seedling tests with several predominant Pst races in the US under controlled greenhouse conditions and at multiple locations subject to natural infection for several years. To map the resistance gene(s) and to transfer it to common wheat, a cross was made between PI 480148 and susceptible common wheat genotype Avocet S (AvS). Resistant F-3 plants with 42 chromosomes were selected cytologically and by testing with Pst race PST-100. A total of 157 F-4 plants from a single F-3 plant with 2n = 42 tested with PST-100 segregated in a 3 resistant: 1 susceptible ratio, indicating that a single dominant gene from PI 480148 conferred resistance. Using the F-3:4 population and the resistance gene-analog polymorphism (RGAP) and simple sequence repeat (SSR) markers, the gene was mapped to the long arm of chromosome 2B. SSR marker Xwmc441 and RGAP marker XLRRrev/NLRRrev (350) flanked the resistance gene by 5.6 and 2.7 cM, respectively. The effective resistance of the gene to an Australian Pst isolate virulent to Yr5, which is also located on 2BL and confers resistance to all US Pst races, together with an allelism test of the two genes, indicated that the gene from PI 480148 is different from Yr5 and should be a new and useful gene for resistance to stripe rust. Resistant common wheat lines with plant types similar to AvS were selected for use in breeding programs. C1 [Xu, L. S.; Kang, Z.

Muscle-type nAChRs located in the motor endplate region of muscle fibers play an integral role in muscle contraction and thus motor function. The toxicity and teratogenicity of many plants (which results in millions of dollars in losses annually to the livestock industry) are due to various toxins that bind to nAChRs including deltaline and methyllycaconitine (MLA) from larkspur (Delphinium) species, and nicotine and anabasine from tobacco (Nicotiana) species. The primary result of the actions of these alkaloids at nAChRs is neuromuscular paralysis and respiratory failure. The objective of this study was to further characterize the motor coordination deficiencies that occur upon exposure to a non-lethal dose of nAChR antagonists MLA and deltaline as well as nAChR agonists nicotine and anabasine. We evaluated the effect of nAChR agonists and antagonists on the motor function and coordination in mice using a balance beam, grip strength meter, rotarod, open field analysis and tremor monitor. These analyses demonstrated that within seconds after treatment the mice had significant loss of motor function and coordination that lasted up to 1 min, followed by a short period of quiescence. Recovery to normal muscle coordination was rapid, typically within approximately 10 min post-dosing. However, mice treated with the nAChR agonist nicotine and anabasine required a slightly longer time to recover some aspects of normal muscle function in comparison to mice treated with the nAChR antagonist MLA or deltaline.

TI Evaluation of commercial products for personal protection against mosquitoes SO ACTA TROPICA LA English DT Article DE Culex pipiens; Aedes albopictus; Personal repellent; Diffusers; Wristbands; Sonic device; Transdermal patch ID BITING PRESSURE; REPELLENTS; DISEASE AB Human landing catch studies were conducted in a semi-field setting to determine the efficacy of seven commercial products used for personal protection against mosquitoes. Experiments were conducted in two empty, insecticide free, mesh-enclosed greenhouses, in Israel, with either 1500 Aedes albopictus or 1500 Culex pipiens released on consecutive study nights. The products tested in this study were the OFF!(R) Clip-On (TM) Mosquito Repellent (Metofluthrin 31.2%) and the Terminix (R) ALLCLEAR (R) Sidekick Mosquito Repeller (Cinnamon oil 10.5%; Eugenol 13%; Geranium oil 21%; Peppermint 53%; Lemongrass oil 2.6%), which are personal diffusers; Super Band (TM) Wristband (22% Citronella oil) and the PIC (R) Citronella Plus Wristband (Geraniol 15%; Lemongrass oil 5%, Citronella oil 1%); the Sonic Insect Repeller Keychain; the Mosquito Guard Patch (Oil of Lemon Eucalyptus 80 mg), an adhesive-backed sticker for use on textiles; and the Mosquito Patch (vitamin B1 300 mg), a transdermal patch. It was determined that the sticker, transdermal patch, wristbands and sonic device did not provide significant protection to volunteers compared with the mosquito attack rate on control volunteers who were not wearing a repellent device. The personal diffusers: OFF!(R) Clip-On (TM) and Terminix (R) ALLCLEAR (R) Sidekick - provided superior protection compared with all other devices in this study. These diffusers reduced biting on the arms of volunteers by 96.28% and 95.26% respectively, for Ae. albopictus, and by 94.94% and 92.15% respectively, for Cx. pipiens. In a second trial conducted to compare these devices directly, biting was reduced by the OFF!(R) Clip-On (TM) and the Terminix (R) ALLCLEAR (R) by 87.55% and 92.83%, respectively, for Ac. albopictus, and by 97.22% and 94.14%, respectively, for Cx. pipiens. There was no significant difference between the performances of the two diffusers for each species. (C) 2012 Elsevier B.V. All rights reserved.

Both the reduced elastic modulus and the hardness of non-embedded cell walls were found to be lower than those of the embedded samples, proving that the embedding medium used for specimen preparation on cellulosic material during nano-indentation can modify cell-wall properties. This leads to structural and chemical changes in the cell-wall constituents, changes that may significantly alter the material properties. Further investigation was carried out to detect the influence of different vacuum times on the cell-wall mechanical properties during the embedding procedure. Interpretation of the statistical analysis revealed no linear relationships between vacuum time and the mechanical properties of cell walls. The quantitative measurements confirm that low-viscosity resin has a rapid penetration rate early in the curing process. Finally, a novel sample preparation method aimed at preventing resin diffusion into lignocellulosic cell walls was developed using a plastic film to wrap the sample before embedding. This method proved to be accessible and straightforward for many kinds of lignocellulosic material, but is especially suitable for small, soft samples.

Current efforts to characterize PM emissions from AFOs generally examine variations in mass concentration and particle size distributions over time and space, but these methods do not provide information on the sources of the PM captured. Raman microscopy was employed as a non-destructive method to quantify the contributions of source materials to PM10 emitted from a large cattle feedlot. Raman spectra from potential source materials (dust from unpaved roads, manure from pen surface, and cattle feed) were compiled to create a spectral library. Multivariate statistical analysis methods were used to identify specific groups composing the source library spectra and to construct a linear discriminant function to identify the source of particles collected on PM-to sample filters. Cross validation of the model resulted in 99.76% correct classification of source spectra in the training group. Source characterization results from samples collected at the cattle feedlot over a two-day period indicate that manure from the cattle pen surface contributed an average of 78% of the total PM10 particles, and dust from unpaved roads accounted for an average of 19% with minor contributions from feed. Results of this work are promising and provide support for further investigation into an innovative method to identify agricultural PM10 sources accurately under different meteorological and management conditions.

This study investigated differences in the PSD measurements by four PSD analyzers: LS13 320 multi-wave length laser diffraction particle size analyzer, LS230 laser diffraction particle size analyzer, LA-300 laser scattering particle size analyzer, and Coulter Counter Multisizer3 (CCM3). Simultaneously collected total suspended particulate (TSP) samples in a commercial egg production house were analyzed by the four analyzers for PSDs. In addition, four types of testing powders (limestone, starch, No3 micro aluminum, and No.5 micro aluminum) were also analyzed by these four PSD analyzers. The results suggest when comparing measured mass median diameters (MMDs) and geometric standard deviations (GSD) of the PSDs, the laser diffraction method (LS13 320, LS230 and LA-300) provided larger MMDs and broader distributions (GSDs) than the electrical sensing zone method (CCM3) for all samples. When comparing mass fractions of PM10 and PM2.5 between the measured values and the lognormal fitting values derived from the measured MMDs and GSDs, lognormal fitting method produced reasonably accurate PM10 mass fraction estimations (within 5%), but it failed to produce accurate PM2.5 mass fraction estimations. The measured PM2.5 mass fractions significantly differed from the lognormal fitting PM2.5 fractions and the mean differences reached as high as 95%. It is strongly recommended that when reporting a PSD of certain PM samples, in addition to MMD and GSD, the mass fractions of PM10 and PM2.5 should also be reported. (C) 2012 Elsevier Ltd.

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

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

Despite the development of numerous mathematical models for predicting ammonia emission, the interactions between CO2 emission, manure pH, and ammonia emission are not completely understood. Others have recognized that CO2 emission from manure can increase the surface pH, and so increase the rate of NH3 emission, but this interaction has not been completely described or quantified. In this work, we present a model of simultaneous NH3 and CO2 emission that includes equilibrium acid/base reactions, kinetically-limited CO2 hydration/dehydration reactions, and diffusive transport. Our model accurately predicted the increase in NH3 emission from simple solutions due to CO2 emission, while an equilibrium-only model did not. Model predictions showed that when NH3 and CO2 emission occur simultaneously, CO2 emission generally increases NH3 emission rate by causing an elevation in surface pH. For thin stagnant layers, this response occurs under a wide range of conditions, although the magnitude of the effect is dependent on manure composition, temperature, surface mass transfer coefficient, and other parameters. Kinetically-limited CO2 hydration/dehydration reactions moderate this interaction, so equilibrium-based models tend to over-predict NH3 emission in the absence of significant carbonic anhydrase activity. Predicted emission from deep, mixed manure showed less dependence on CO2 emission, although higher rates of CO2 hydration/dehydration increase this effect. Interactions between CO2 and NH3 emission influence the effect of model parameters on NH3 emission and result in some unexpected responses. Future work should clarify the processes controlling CO2 speciation and transport in manure, including CO2 minerals, bubble transport, and CO2 hydration/dehydration rates. Our model can inform the development of simpler models for estimating NH3 emission, and the design of experiments aimed at quantifying processes that influence NH3 emission from manure. The effects of CO2 on NH3 emission deserve more attention, and both experimental and modeling approaches are needed to understand the interactions that control NH3 emission.

However, there has been little regard to the extreme variation and potential inaccuracies caused by air velocity or sweep air flow rates that are either too low or too high to simulate field conditions. There is a need for correction factors to standardize flux chamber and wind tunnel measurements. In this manuscript, we present results of water evaporative flux and VOC flux measurements with the EPA flux chamber and a small wind tunnel. In the EPA flux chamber, water evaporative flux was positively correlated with sweep air flow rate (SAFR) between 1 and 20 L min(-1) (r(2) = 0.981-0.999) and negatively correlated with sweep air relative humidity between 0 and 80% (r(2) = 0.982-0.992). Emissions of gas-film controlled compounds like NH3 and VOC at AFOs were positively correlated with evaporation rates between 0.6 and 2.8 mm d(-1). We demonstrate a simple methodology for standardizing and comparing different chamber types by measuring water evaporation within the chamber using a gravimetric mass balance approach under controlled laboratory conditions. A water evaporative flux ratio correction factor (EFRCF) was used to improve the accuracy of field-measured VOC and NH3 chamber flux measurements. In a field study, both the EPA flux chamber (SAFR = 5 L min(-1)) and small wind tunnel (SAFR = 1 L min(-1)) underestimated the true field emissions of VOC, with EFRCFs of 2.42 and 3.84, respectively.

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

TI Measuring gas emissions from animal waste lagoons with an inverse-dispersion technique SO ATMOSPHERIC ENVIRONMENT LA English DT Article DE Treatment lagoon emission; Backward Lagrangian stochastic; Inverse-dispersion technique; Optimal anemometer location; Accuracy; Wind interference ID TO-AIR EMISSIONS; AMMONIA EMISSIONS; METHANE EMISSIONS; FIELD TRIAL; MODEL; FARM AB Measuring gas emissions from treatment lagoons and storage ponds poses challenging conditions for existing micrometeorological techniques. This is due to non-ideal wind conditions, such as those induced by trees and crops surrounding the lagoons, and lagoons with dimensions too small to establish equilibrated microclimate conditions within the water boundary. This study evaluated the accuracy of an emerging backward Lagrangian stochastic (bLS) inverse-dispersion technique to measure lagoon emissions. It used a fabricated floating emission source with known emission rates from an irrigation pond that resembled typical treatment lagoon environments. The measured parameters were wind statistics and downwind path-integrated concentrations. Anemometers were located on the upwind, downwind, or side berm parallel to wind. Additionally, the berm surface was deliberately roughened during the summer by placing pine straw bales along the berms to simulate vegetation growth. Regardless of the surface roughness, when the surrounding vegetation (i.e. corn field) was short during spring and fall, using an anemometer located on the upwind berm produced the most accurate results (0.93 +/- 0.19). However, during the summer, the adjacent corn crop grew more than 2 m high. Consequently, the anemometer had to be moved to the side berm. This resulted in a decrease in accuracy to 0.81 +/- 0.18. Yet, even with less than idealized conditions, the bLS inverse-dispersion technique still produced reasonably accurate emission rates. This demonstrated the robustness of this easy-to-use bLS inverse-dispersion technique for complex agricultural emission measurements. Published by Elsevier Ltd.

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

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

Soil erosion by water has become a problem worldwide and as concerns about the environment continue to grow, soil erosion remains a very active area of scientific research. In this study, based on advanced remote sensing and Geographic Information Systems (GIS) technologies, the influences of precipitation, soil, topography and vegetation on soil erosion sensitivity are evaluated. An index system and the classification standard for soil erosion sensitivity assessment in the Tongbai-Dabie Mountainous area are established with soil erosion sensitivity being evaluated and analyzed in order to provide a scientific basis for controlling soil erosion and for making sound ecological engineering decisions. According to the regional conditions, sensitivity is classified into five levels: insensitive, mild, moderate, high and extreme. The distribution of erosion sensitivity for the region is analyzed and the various impacts are discussed. The results show that the sensitivity of the Tongbai-Dabie Mountainous area to soil erosion is relatively high, with 4634% of the total area above the moderate level, and 44.30% and 9.36% rated at the mild and insensitive levels, respectively. In regards to the spatial distribution, the sensitivity levels decrease from south to north, with highly sensitive areas found mainly in the south in the areas of Jinzhai, Huoshan, Shangcheng, Yuexi, and Shucheng. The distribution of soil erosion sensitivity levels was very consistent with the intensity of soil erosion. Areas of high sensitivity are found to have severe areas of soil erosion, indicating that regional soil erosion is highly influenced by natural factors, although in some areas it is evident that the impact of human activities has played a significant role in exacerbating the problem. The results of this investigation serve to advance efforts to reduce the impacts soil erosion in the region and prevent further erosion in areas having high erosion sensitivities.

TI An empirical investigation of gully widening rates in upland concentrated flows SO CATENA LA English DT Article DE Soil erosion; Channel expansion; Shallow overland flow; Gully; CREAMS model ID EROSION; RILLS; MIGRATION; DISCHARGE; WIDTH; MORPHODYNAMICS; HYDRAULICS; HEADCUTS; GROWTH; AREAS AB Soil erosion, in its myriad forms, devastates arable land and infrastructure. As an integral landscape feature, gully erosion is a complex system as its evolution is controlled by upstream migration of a gully head (headcut face), incision of the gully bed (plunge pool) and gravitational mass-movement (widening) on gully channel sidewalls. Bed incision is often limited by the presence of a less erodible soil layer. When erosion reaches such a layer, the gully typically widens, creating a wide shallow cross section. Once a gully is initiated, transport and deposition of the eroded soil and widening of the channel further govern its evolution. Our knowledge of these processes within agricultural regions, however, is still quite limited with theory largely borrowed from river hydraulics. Experiments were conducted to examine gully expansion (widening) as a function of channel slope and overland flow discharge. Packed soil beds were subjected to simulated rainstorms followed by clear-water overland flow. As bed slope and discharge increased, channel widening increased. An empirical equation, based upon measured channel width from constant discharge experiments, was developed in terms of slope and discharge. By further quantifying key aspects of gully erosion processes, results from this experimental campaign will significantly improve soil erosion prediction technology for use in agricultural regions.

Predicted rates of change are often small relative to interannual variability, and few locations have sufficiently comprehensive long-term records of environmental variables to enable researchers to observe the fine-scale patterns that may be important to understanding the influence of climate change on biological systems at the taxon, community, and ecosystem levels. We examined a 50-year meteorological and hydrological record from the Hubbard Brook Experimental Forest (HBEF) in New Hampshire, an intensively monitored Long-Term Ecological Research site. Of the examined climate metrics, trends in temperature were the most significant (ranging from 0.7 to 1.3 A degrees C increase over 40-50 year records at 4 temperature stations), while analysis of precipitation and hydrologic data yielded mixed results. Regional records show generally similar trends over the same time period, though longer-term (70-102 year) trends are less dramatic. Taken together, the results from HBEF and the regional records indicate that the climate has warmed detectably over 50 years, with important consequences for hydrological processes. Understanding effects on ecosystems will require a diversity of metrics and concurrent ecological observations at a range of sites, as well as a recognition that ecosystems have existed in a directionally changing climate for decades, and are not necessarily in equilibrium with the current climate.

The value of pollination to agriculture, provided primarily by bees, is >$200 billion/year worldwide, and in natural ecosystems it is thought to be even greater. However, no monitoring program exists to accurately detect declines in abundance of insect pollinators; thus, it is difficult to quantify the status of bee communities or estimate the extent of declines. We used data from 11 multiyear studies of bee communities to devise a program to monitor pollinators at regional, national, or international scales. In these studies, 7 different methods for sampling bees were used and bees were sampled on 3 different continents. We estimated that a monitoring program with 200250 sampling locations each sampled twice over 5 years would provide sufficient power to detect small (25%) annual declines in the number of species and in total abundance and would cost U.S.$2,000,000. To detect declines as small as 1% annually over the same period would require >300 sampling locations. Given the role of pollinators in food security and ecosystem function, we recommend establishment of integrated regional and international monitoring programs to detect changes in pollinator communities.

One common approach for determining corridor locations is least-cost corridor (LCC) modeling, which uses algorithms within a geographic information system to search for routes with the lowest cumulative resistance between target locations on a landscape. However, the presentation of multiple LCCs that connect multiple locations generally assumes all corridors contribute equally to connectivity, regardless of the likelihood that animals will use them. Thus, LCCs may overemphasize seldom-used longer routes and underemphasize more frequently used shorter routes. We hypothesize that, depending on conservation objectives and available biological information, weighting individual corridors on the basis of species-specific movement, dispersal, or gene flow data may better identify effective corridors. We tested whether locations of key connectivity areas, defined as the highest 75th and 90th percentile cumulative weighted value of approximately 155,000 corridors, shift under different weighting scenarios. In addition, we quantified the amount and location of private land that intersect key connectivity areas under each weighting scheme. Some areas that appeared well connected when analyzed with unweighted corridors exhibited much less connectivity compared with weighting schemes that discount corridors with large effective distances. Furthermore, the amount and location of key connectivity areas that intersected private land varied among weighting schemes. We believe biological assumptions and conservation objectives should be explicitly incorporated to weight corridors when assessing landscape connectivity. These results are highly relevant to conservation planning because on the basis of recent interest by government agencies and nongovernmental organizations in maintaining and enhancing wildlife corridors, connectivity will likely be an important criterion for prioritization of land purchases and swaps.

Using artificial pupal chambers, we documented the time required by teneral adults at three temperatures (20, 25, and 30 degrees C), 60-80% RH, and a photoperiod of 16:8 (L:D) h to initiate boring after eclosion and subsequently bore completely through a 7-mm (range, 3-11 mm) layer of Norway maple wood (Acer platanoides L.). In total, 218 laboratory-reared pupae from the Chicago, IL, or Inner Mongolia, China, populations were used in the study. Females (1.54 +/- 0.03 g) weighed signi_cantly more than males (1.12 +/- 0.03 g), but the average weights of the beetles emerging in each temperature did not differ. Adult weight was positively correlated with exit hole diameter (diameter[mm] = 2.2 * weight [g] + 7.9). The rate at which beetles bored through the wood (136, 178, and 168 mm(3)/d at 20, 25 and 30 degrees C, respectively) significantly differed between temperatures but did not differ with beetle weight. Temperature had a significant effect on the time it took adults to initiate boring (7, 5, and 4 d at 20, 25, and 30 degrees C, respectively) and subsequently to complete boring to emerge (5, 4, and 4 d at 20, 25, and 30 degrees C, respectively). This suggests that beetles require more than a week to progress from eclosion to emergence in wood, even at summer temperatures. This information on A. glabripennis basic biology is critical for developing phenology models that are used to time exclusion and eradication methodologies. C1 [Sanchez, V.; Keena, M.

TI Host Density Drives Spatial Variation in Parasitism of the Alfalfa Weevil, Hypera postica, Across Dryland and Irrigated Alfalfa Cropping Systems SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE density-dependence; disturbance; natural enemy; population; spatial variation ID BIOLOGICAL-CONTROL; NATURAL ENEMIES; CURCULIONIDAE; COLEOPTERA; HABITATS; FLUCTUATIONS; MANAGEMENT; INSECTS AB Classical biological control against the alfalfa weevil, Hypera postica (Gyllenhal), a destructive pest of alfalfa (Medicago sativa L.), has resulted in the establishment of nine parasitoid species in the United States. Despite widespread redistribution of a number of species, there remains little postrelease data on their establishment and potential effectiveness in many regions. I surveyed parasitoids associated with alfalfa weevil larvae across 30 or more sites in eastern Montana and western North Dakota over 2 yr. Replicate sites were sampled in two habitat types that differ in their physical characteristics, flood-irrigated and dryland alfalfa fields. Irrigated systems are more productive but also more intensively disturbed habitats because of increased harvest frequency and repeated flooding. Given evidence that both habitat disturbance and herbivore density, which often increases with productivity, can influence parasitoid dynamics, I predicted that parasitism levels, the relative importance of different species, or both, would differ across these two system types. Of four larval parasitoid species released previously or recovered in the region, two were found in this study, Bathyplectes curculionis (Thomson) and Oomyzus incertus (Ratzenberg), with average levels of parasitism across habitat types and years of 37.2 and 3.5%, respectively. Parasitism levels differed between habitat types, but the effect was driven by concomitant differences in host densities that were higher in irrigated than dryland fields. Parasitoid responses to host density varied across years and species. B. curculionis exhibited positive density dependence in parasitism across sites in 2009 and negative density dependence in 2010 when host densities were higher regionally. In contrast, O. incertus exhibited positive density dependence in 2010. Our results suggest that these species may be differentially effective at different host densities. Thus, variation in host density could represent an important axis along which parasitoids exhibit spatial complementarity in function. C1 ARS, USDA, No Plains Agr Res Lab, Sidney, MT 59270 USA.

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

TI Influence of Trap Design on Upwind Flight Behavior and Capture of Female Grape Berry Moth (Lepidoptera: Tortricidae) With a Kairomone Lure SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE olfactory cue; visual cue; kairomone; integrated pest management; flight tunnel ID ENDOPIZA-VITEANA LEPIDOPTERA; CODLING MOTH; PARALOBESIA-VITEANA; SEX-PHEROMONE; FRUIT VOLATILES; CYDIA-POMONELLA; INCREASED CATCH; OLFACTORY CUES; HOST PLANTS; VISUAL CUES AB Oil-coated clear panel traps baited with a host plant-based kairomone lure have successfully been used for monitoring female grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae), but low capture rates as well as difficulty in servicing these traps makes them unsuitable for commercial use. We compared the performance of different trap designs in a flight tunnel and in a vineyard by using a 7-component synthetic kairomone blend, with a focus on trap visual cues. In flight tunnel experiments, a clear delta trap performed better than other traps. When we tested clear delta, green delta, or clear wing traps baited with a cut grape shoot, >50% of female grape berry moths made complete upwind flights. However, the clear delta trap was the only design that resulted in female moths entering the trap. Similar results were observed when females were tested with different traps (clear delta, green delta, white delta, clear wing, or green wing traps) baited with the kairomone lure. Adding a visual pattern that mimicked grape shoots to the outside surface of the clear delta trap resulted in 66% of the females that made upwind flights entering the trap. However, the positive effect of adding a visual pattern to the trap was not observed in a vineyard setting, where clear delta traps with or without a visual pattern caught similar numbers of females. Still, the number of male and female grape berry moths captured in clear delta traps with or without a visual pattern was not significantly different from the number of male and female grape berry moths captured in panel traps, suggesting that the use of these delta traps could be a less cumbersome alternative to oil-coated panel traps for monitoring female grape berry moth.

Recognising this threat, an international standard for the treatment of WPM (ISPM 15) is being implemented by many countries. In addition, the United States has considered application of similar requirements to WPM used in domestic and bilateral trade with Canada. We use a domestic margin-inclusive version of the Global Trade Analysis model to estimate the economic and trade impacts of ISPM 15, along with alternatives of varying stringency. We also estimate the economic impacts of one of the benefits of ISPM 15; averted United States forest owner timber losses. ISPM 15 is likely to have a small, negative effect on exports and economic welfare for most countries. However, there is significant regional and sectoral variation, depending on the product mix traded. If ISPM 15 requirements are extended to United States domestic trade, the impacts on the United States are stronger. Inclusion of averted United States timber losses partly, but not completely, offset welfare and trade impacts of the ISPM 15 treatment. These results must be tempered with the additional benefits of ISPM 15 in terms of potential averted household and environmental damages. (C) 2012 Elsevier B.V. All rights reserved.

A sensor array is used that is comprised of six interdigitated microelectrodes coated with nanofiber films of poly(lactic acid)/mutliwalled carbon nanotube (MWCNT) composites. Fiber films are deposited directly on the interdigitated electrodes surface by solution blow spinning. Fiber film thickness is varied by using different deposition times (1, 3, and 15 min). Analysis of scanning electron microscopy and transmission electron microscopy micrographs indicates that average fiber diameters are 400 nm for neat poly lactic acid (PLA) and 200 nm for the PLA/MWCNT composite. The MWCNT is poorly dispersed in the PLA fiber matrix and formed aggregates interspersed throughout the fiber length. There are also MWCNTs exposed or partially exposed at the fiber surface. Fiber films containing-MWCNT (1%) give the highest dc conductivity values and the most linear I-V profiles at room temperature. Sensor arrays with thin fiber film coatings (1 min deposition time) provide the best result for discriminating potable water samples using principal component analysis (PCA). The flow-cell electronic tongue coupled with PCA is used to discriminate potable water samples from non-potable water contaminated with metals or traces of pesticides.

SEM cells were injected into the tail vein and engraftment was monitored by flow cytometry. Once engraftment was observed, the chemotherapeutic potential was examined by injecting mice intraperitoneally with curcumin (5 mg/kg body weight) dissolved in dimethylsulfoxide (DMSO) or DMSO alone (control) every other day, or vincristine (0.5 mg/kg body weight) 3 times per week for 4 weeks (n=16 per group). The intraperitoneal administration of curcumin did not inhibit the growth of the leukemia cells. To determine the efficacy of oral curcumin, mice were fed a control diet or a diet containing 0.5% w/w curcumin 3 weeks prior to the injection of the leukemia cells and throughout the experimental period (n=16 per group). To determine whether dietary curcumin can enhance the efficacy of a conventional chemotherapeutic agent, vincristine was injected intraperitoneally into leukemic mice fed the different diets. Dietary curcumin did not delay the engraftment or growth of leukemia cells, or sensitize the cells to vincristine. Liquid chromatography-tandem mass spectrometry analyses of mouse sera showed that curcumin rapidly metabolized to glucuronidated and sulfated forms within 1 h post-injection and these were the major curcumin metabolites found in the sera of the mice fed the curcumin diet. In contrast to the findings in previous in vitro models, the current data indicate that orally or parenterally administered curcumin is not a potent preventive agent against high-risk t(4;11) acute lymphoblastic leukemia.

TI Visual and chemical cues affecting the detection rate of the emerald ash borer in sticky traps SO JOURNAL OF APPLIED ENTOMOLOGY LA English DT Article DE Agrilus planipennis; Buprestidae; manuka oil; mate-finding; phoebe oil ID AGRILUS-PLANIPENNIS COLEOPTERA; MATING-BEHAVIOR; BUPRESTIDAE; ATTRACTION; VOLATILES; TREES; COL. AB Using sticky traps, we compared the efficacy of chemical and visual lures, both alone and in combination, for improving the detection of populations of the emerald ash borer (EAB), Agrilus planipennis. Ash leaflets to which EAB visual decoys were pinned and coated with sticky material were able to trap EAB with as high a rate of detection as large sticky visually unbaited prism traps currently used in wide-scale EAB surveillance programs in North America, in a high-density area. Both the sticky leaf traps and prism traps captured more EAB when a point source of plant odours, either manuka or phoebe oil, was deployed with the trap. For the sticky leaf traps, the shape of the EAB visual decoy lure was found to be important in optimizing the detection rate. Either an entire dead beetle or else two elytra placed side by side to mimic a resting beetle resulted in optimal trap performance. When two elytra were placed end to end or else other body parts were deployed, the traps lost their efficacy. Small green plastic surfaces to which EAB visual decoys were pinned were found to be fairly good substitutes for live ash leaflets, but the rate of beetle detection was reduced significantly from that of the ash leaflet plus EAB decoy. Throughout all experiments, a clear male bias occurred in sticky leaf traps when EAB visual decoys were placed on the traps. The implications of these findings for developing new trapping designs for EAB and other forest buprestids are discussed. C1 [Domingue, M. J.; Lelito, J. P.; Tumlinson, J. H.; Baker, T.

TI Carbohydrate Nutrition Differs by Diabetes Status and Is Associated with Dyslipidemia in Boston Puerto Rican Adults without Diabetes SO JOURNAL OF NUTRITION LA English DT Article ID DIETARY GLYCEMIC INDEX; DISEASE RISK-FACTORS; DENSITY-LIPOPROTEIN CHOLESTEROL; FOOD-FREQUENCY QUESTIONNAIRE; CARDIOVASCULAR-DISEASE; WHITE RICE; JAPANESE MEN; FIBER INTAKE; INSULINEMIC INDEXES; METABOLIC SYNDROME AB Puerto Rican adults have a greater prevalence of type 2 diabetes (T2D) and lower HDL-cholesterol (HDL-C) than the general U.S. population. Carbohydrate nutrition may play a role in this disparity. Cross-sectional analyses included data from 1219 Puerto Ricans aged 45-75 y enrolled in the Boston Puerto Rican Health Study. Using the Pearson chi-square test and ANCOVA, lifestyle characteristics and dietary intake, as assessed by semiquantitative FFQ, were compared by T2D status based on fasting plasma glucose concentration and medication use. Food source rankings for carbohydrate, dietary glycemic load (GL), and fiber were obtained using the SAS procedure PROC RANK. Geometric mean plasma HDL-C and TG concentrations were compared across quintiles of dietary carbohydrate, glycemic index (GI), GL, and fiber by using ANCOVA and tests for linear trend. In multivariable analyses, individuals with T2D (39.5%) had lower dietary carbohydrate, GL, and total sugar intake from lower intake of sugar, fruit drinks, and soda compared with those without T2D. In individuals without T2D, dietary carbohydrate and GL were inversely associated with HDL-C (P < 0.0001). Associations between dietary fiber and HDL-C were confounded by carbohydrate intake, apparently from concurrent consumption of legumes with white rice, a refined carbohydrate food. No associations were observed between carbohydrate, dietary GI, GL, or fiber and TG. In conclusion, individuals with T2D showed evidence of dietary modification. Among those without diabetes, a high intake of refined carbohydrates was associated with decreased HDL-C. Longitudinal research on carbohydrate nutrition in relation to diabetes risk factors and blood lipids in Puerto Ricans is warranted. J. Nutr. 143: 182-188, 2013.

In Mexico, milk is a well-accepted vehicle for the administration of micronutrients, including VA, to preschoolers. Thus, we conducted a randomized, controlled, clinical trial to investigate the efficacy of daily consumption of 250 mL of VA-fortified milk (which provided 196 retinol equivalents/d) for 3 mo on VA stores in mildly to moderately VAD (serum retinol concentration 0.35-0.7 mu mol/L) preschoolers who were not enrolled in a food assistance program. Twenty-seven mildly to moderately VAD children were randomly assigned based on screening measurements to either the intervention (n = 14) or control group (n = 13) (children in the control group did not receive placebo). All children in the control group and 79% (n = 11) of the children in the intervention group completed the study. The total body VA (TBVA) pool size was estimated using the deuterated retinol dilution technique before and after the intervention. After 3 mo, median changes in the serum retinol concentration for the intervention and control groups were 0.13 and -0.21 mu mol/L, respectively (P = 0.009). Median changes in the TBVA stores were 0.06 and 0.01 mmol, respectively (P = 0.006) and estimated median changes in the liver VA concentration were 0.09 and 0.01 mu mol/g, respectively (P = 0.002). The VA-fortified milk was well accepted among preschoolers and significantly increased TBVA stores, liver VA stores, and serum retinol concentration, indicating that it may be an effective means to ameliorate VAD in young Mexican children.

They have had a long history that goes back to 1892 and are unique, as they are the only databases available in the public domain that perform these functions. There are 4 major food and nutrient databases released by the Beltsville Human Nutrition Research Center (BHNRC), part of the USDA's Agricultural Research Service. These include the USDA National Nutrient Database for Standard Reference, the Dietary Supplement Ingredient Database, the Food and Nutrient Database for Dietary Studies, and the USDA Food Patterns Equivalents Database. The users of the databases are diverse and include federal agencies, the food industry, health professionals, restaurants, software application developers, academia and research organizations, international organizations, and foreign governments, among others. Many of these users have partnered with BHNRC to leverage funds and/or scientific expertise to work toward common goals. The use of the databases has increased tremendously in the past few years, especially the breadth of uses. These new uses of the data are bound to increase with the increased availability of technology and public health emphasis on diet-related measures such as sodium and energy reduction. Hence, continued improvement of the databases is important, so that they can better address these challenges and provide reliable and accurate data. J. Nutr. 143: 241S-249S, 2013.

The effect of CLA on fatty acid compositions of adipose tissue and muscle and whether DHA can prevent those CLA-induced changes in fatty acid composition is not known. Methods: We investigated if DHA fed concomitantly with CLA for 4 weeks will prevent the CLA-induced changes in fatty acid compositions of liver, adipose, and muscle lipids in C57BL/6N female mice. We also examined changes in expression of adipose tissue genes involved in fatty acid synthesis, oxidation, uptake, and lipolysis. Results: CLA supplementation increased liver fat and decreased total n-3 polyunsaturated fat (PUFA) concentration. DHA not only prevented the CLA-induced changes in liver fat, but also increased n-3 PUFA by >350% as compared with the control group. CLA decreased adipose weight and the expression of genes involved in fatty acid synthesis, oxidation, and uptake and increased that of uncoupling protein 2 (UCP2). Supplementing DHA along with CLA increased adipose n-3 PUFA by >1000% compared with control group, but did not prevent the CLA-induced changes in mass or gene expression. Both CLA and DHA were incorporated into muscle lipids, but had minor effects on fatty acid composition. Conclusions: Liver, adipose tissue, and muscle responded differently to CLA and DHA supplementation. DHA prevented CLA-induced increase in liver fat but not loss of adipose mass.

S., and Stenger, D. C. 2013. Roguing with replacement in perennial crops: Conditions for successful disease management. Phytopathology 103:117-128. Replacement of diseased plants with healthy plants is commonly used to manage spread of plant pathogens in perennial cropping systems. This strategy has two potential benefits. First, removing infected plants may slow pathogen spread by eliminating inoculum sources. Second, replacing infected plants with uninfected plants may offset yield losses due to disease. The extent to which these benefits are realized depends on multiple factors. In this study, sensitivity analyses of two spatially explicit simulation models were used to evaluate how assumptions concerning implementation of a plant replacement program and pathogen spread interact to affect disease suppression. In conjunction, effects of assumptions concerning yield loss associated with disease and rates of plant maturity on yields were simultaneously evaluated. The first model was used to evaluate effects of plant replacement on pathogen spread and yield on a single farm, consisting of a perennial crop monoculture. The second model evaluated effects of plant replacement on pathogen spread and yield in a 100 farm crop growing region, with all farms maintaining a monoculture of the same perennial crop. Results indicated that efficient replacement of infected plants combined with a high degree of compliance among farms effectively slowed pathogen spread, resulting in replacement of few plants and high yields. In contrast, inefficient replacement of infected plants or limited compliance among farms failed to slow pathogen spread, resulting in replacement of large numbers of plants (on farms practicing replacement) with little yield benefit. Replacement of infected plants always increased yields relative to simulations without plant replacement provided that infected plants produced no useable yield. However, if infected plants produced useable yields, inefficient removal of infected plants resulted in lower yields relative to simulations without plant replacement for perennial crops with long maturation periods in some cases.

Phytopathology 103:146-155. The TrigoCor strain of Bacillus amyloliquefaciens provides consistent control against Fusarium head blight of wheat in controlled settings but there is a lack of disease and deoxynivalenol suppression in field settings. Since production of antifungal compounds is thought to be the main mode of action of TrigoCor control, we quantified levels of a key family of antifungal metabolites, iturins, as well as monitored Bacillus populations on wheat spikes over 14 days post-application in both the greenhouse and the field. We found that initial iturin levels on spikes in the greenhouse were three times greater than on spikes in the field, but that by 3 days post-application, iturin levels were equivalent and very low in both settings. We also determined that iturins declined rapidly over a 3-day post-application period on wheat spikes in both environments, despite the presence of significant Bacillus populations. Greenhouse trials and antibiosis tests indicated that the lower iturin levels on wheat spikes in the field could be a major factor limiting disease control in field settings. Future efforts to improve Bacillus disease control on wheat spikes and in the phyllosphere of various plants should focus on maintaining higher levels of iturins over critical infection periods.

(L perenne) is a continuous distribution of diameters, or a collection of discrete diameters classes. Plants from tillers of five clones were grown in a local soil amended with lime. Roots were excavated after they were grown in soil for 54 days, washed and imaged with both a commercial scanner (94 px mm(-1)) and a high resolution, locally built, imager (204 px mm(-1)). Images were converted to diameter class length data with WinRhizo. Scanned images did not have enough resolution to accurately measure fine roots diameters (< 0.09 mm diam.). Therefore the high resolution images were used. The diameter class length distributions (DCLD) of these images demonstrated diameter class clusters (meso diameter classes) which could be modeled with a non-linear Gaussian (normal) curve model. Recreating the whole root system from a compilation of the DCLD, regenerated from the three parameters of each of the Gaussian curves for the root system, produced a distribution visually identical to the original whole root system curve. L perenne root systems are a collection of meso diameter classes easily described by non-linear Gaussian models. The data set of the parameters from these models is much smaller than a WinRhizo data set, and can reconstruct the original whole system DCLD. C1 ARS, USDA, AFSRC, Beaver, WV 25813 USA.

Plant Dis. 97:201-212. Potassium phosphite (ICP) concentrations that inhibited the germination of 50% of Penicillium digitatum conidia were 229, 334, 360, 469, 498, or 580 mg/liter at pH 3, 4, 5, 6, 7, or 8, respectively. Increasing phosphate content in media reduced phosphite toxicity. To control green or blue mold, fruit were inoculated with P digitatum or P. italicum, then immersed 24 h later in KP, calcium phosphite (CaP), sodium carbonate, sodium bicarbonate, or potassium sorbate for 1 min at 20 Oiler for each at 25 or 50 degrees C. Mold incidence was lowest after potassium sorbate, CaP, or ICP treatments at 50 degrees C. CaP was often more effective than ICP but left a white residue on fruit. KP was significantly more effective when fruit were stored at 10 or 15 C after, treatment compared with 20 degrees C. Acceptable levels of control were achieved only when KP was used in heated solutions or with fungicides. ICP was compatible with imazalil (IMZ) and other fungicides and improved their effectiveness. ICP increased thiabendazole or IMZ residues slightly. Phosphite residues did not change during storage for 3 weeks, except they declined when ICP was applied with IMZ. KP caused no visible injuries or alteration in the rate of color change of citrus fruit in air or ethylene at 5 mu l/liter. C1 [Cerioni, L.; Rapisarda, V.

TI Whole grain consumption is inversely associated with BMI Z-score in rural school-aged children SO PUBLIC HEALTH NUTRITION LA English DT Article DE Obesity; Children; Whole grains; BMI ID BODY-MASS INDEX; DIETARY FIBER; RISK-FACTORS; US CHILDREN; CARDIOVASCULAR-DISEASE; INSULIN SENSITIVITY; METABOLIC SYNDROME; WEIGHT-GAIN; OBESITY; OVERWEIGHT AB Objective: To examine the relationship between intake of whole grains and BMI Z-score in rural children. Design: General linear models and logistic regression were used to examine the cross-sectional associations between whole grain intake and BMI Z-score, prevalence and odds ratios of overweight and obesity. Dietary intake was assessed using the Block Food Screener for ages 2-17 years. Children were classified into three categories according to servings of whole grain intake: <1.0 serving/d, 1.0-1.5 servings/d and >1.5 servings/d. Setting: The CHANGE (Creating Healthy, Active and Nurturing Growing-up Environments) study, an obesity prevention intervention in elementary schools in eight rural US communities in California, Mississippi, Kentucky and South Carolina. Subjects: Seven hundred and ninety-two children attending 3rd-6th grade. Results: After adjusting for age, sex, race/ethnicity, physical activity and state of residence, whole grain intake was inversely associated with BMI Z-score (0.90 v. 0.61 in the lowest v. the highest whole grain intake category; P trend=0.01). Children who consumed >1.5 servings of whole grains/d had a 40% lower risk of being obese (OR=0.60; 95% CI 0.38, 0.95, P=0.02) compared with children who consumed <1.0 serving/d. Further adjustment for potential dietary predictors of body weight (fruit, vegetable and dairy intakes) did not change the observed associations. Conclusions: Increasing the intake of whole grains as part of an overall healthy lifestyle may be beneficial for children to achieve and maintain a healthy weight.

This study prospectively examined the longitudinal course of psychopathology, coping, and functioning among 128 directly exposed Kenyan civilian survivors of the 1998 US Embassy bombing in Nairobi. The Diagnostic Interview Schedule/Disaster Supplement assessed predisaster and postdisaster psychiatric disorders and variables related to coping, functioning, safety, and religion near the end of the first and third postdisaster years. Total postdisaster prevalence of posttraumatic stress disorder (PTSD) at the 3-year follow-up was 49; 28 % of the sample still had active PTSD. Delayed-onset PTSD was not observed. Posttraumatic symptoms decayed more slowly in individuals with than those without PTSD. PTSD was more prevalent and chronic than major depression. Those with current PTSD or major depression reported more functioning problems than those without. The length of hospitalization for injuries after the bombing predicted major depression remission, but no predictors of PTSD remission were found. Despite differences in coping and social variables, longitudinal psychopathology in the Nairobi terrorism survivors appeared broadly similar to results in Western disaster populations. These findings contribute to the understanding of disaster mental health in Africa and may have implications for generalizability of psychiatric effects of terrorist attacks around the globe.

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

TI Opportunities for improving risk communication during the permitting process for entomophagous biological control agents: a review of current systems SO BIOCONTROL LA English DT Review DE Biological control; Survey questionnaire; Pest risk analysis; Risk assessment; Risk communication; Permitting process ID NEW-ZEALAND; PERCEPTION; SAFETY; USA AB Concerns about potentially irreversible non-target impacts from the importation and release of entomophagous biological control agents (BCAs) have resulted in increasingly stringent national import requirements by National Plant Protection Organizations worldwide. However, there is a divergence of opinions among regulators, researchers, environmentalists, and the general public on ways to appropriately manage associated risks. Implementation of a comprehensive and effective risk communication process might narrow the opinion gaps. Results from a comprehensive survey conducted in the United States were used to describe communication habits of stakeholders involved in biological control and identify areas that are fundamental in an efficient process. In addition, this study critically reviews risk communication practices and how phytosanitary decisions are communicated in the permitting systems for entomophagous BCAs of several countries to identify risk communication tools used in an effective risk communication framework. The following barriers to efficient risk communication were identified: absence of a formalized risk communication process, undefined risk communication goals and target audiences, lack of credibility and objectivity of information sources, inefficiency of mode of distribution of messages, insufficient public participation, and lack of transparency of decision making processes. This paper suggests the creation and/or enhancement of modes of distribution of risk messages to increase coverage, understanding, and guidance. For instance, messages should be presented in different formats such as internet, brochures, and newspapers. Surveys, public meetings, and trainings/workshops are tools that can be used to characterize stakeholders' diversity and develop risk messages specific to the targeted audience. Implementation of a participatory decision making process will increase stakeholder involvement and trust in the risk management plan. Development of practical mechanisms, such as public hearings will increase all stakeholders' involvement in the risk assessment process. A clear framework describing how public comments will be incorporated in the decision making process should be implemented. Finally, to ensure a streamlined risk communication process, there must be consistency in the messages disseminated by federal, state, and local agencies. C1 [Paraiso, Oulimathe; Kairo, M. T.

TI Biology and ecology of Brazilian elodea (Egeria densa) and its specific herbivore, Hydrellia sp., in Argentina SO BIOCONTROL LA English DT Article DE Biological control; Hydrocharitaceae; Ephydridae; Aquatic weeds ID NAJAS PLANCHON; NEW-ZEALAND; HYDROCHARITACEAE; PHOTOSYNTHESIS; EPHYDRIDAE; DIPTERA; GROWTH; LAKE AB Egeria densa (Hydrocharitaceae) is a submerged macrophyte from South America that is a weed in several countries. It crowds out native plants and hinders water use, causing economic and environmental damage. The leafminer fly Hydrellia sp. 1 (Diptera: Ephydridae), was found feeding in E. densa throughout its Argentine distribution, and is currently the only known specialist herbivore of E. densa. It was reared in the laboratory and tested on 25 plant species. This herbivore can cause heavy defoliation in the laboratory and in the field. Hydrellia sp. 1 was found only on E. densa, but in the laboratory it also developed on two other Hydrocharitaceae species in the same family; Egeria naias, and Elodea callitrichoides. Significant oviposition and feeding were only observed on its primary natural host, and to a lesser degree on E. naias. Field studies indicate Hydrellia sp. 1 is present in the field year round, unless the host plant is prostrate for long periods, or covered by floating macrophytes. These results indicate Hydrellia sp. 1 may be a suitable biocontrol candidate for E. densa. C1 [Walsh, G. Cabrera; Dalto, Y.

TI Evaluation of the Potential Antimicrobial Resistance Transfer from a Multi-Drug Resistant Escherichia coli to Salmonella in Dairy Calves SO CURRENT MICROBIOLOGY LA English DT Article ID GEL-ELECTROPHORESIS; RUMEN PROTOZOA; R-FACTORS; CATTLE; TYPHIMURIUM; PREVALENCE; O157-H7; SHEEP AB Previous research conducted in our laboratory found a significant prevalence of multi-drug resistant (MDR) Salmonella and MDR Escherichia coli (MDR EC) in dairy calves and suggests that the MDR EC population may be an important reservoir for resistance elements that could potentially transfer to Salmonella. Therefore, the objective of the current research was to determine if resistance transfers from MDR EC to susceptible strains of inoculated Salmonella. The experiment utilized Holstein calves (approximately 3 weeks old) naturally colonized with MDR EC and fecal culture negative for Salmonella. Fecal samples were collected for culture of Salmonella and MDR EC throughout the experiment following experimental inoculation with the susceptible Salmonella strains. Results initially suggested that resistance did transfer from the MDR E. coli to the inoculated strains of Salmonella, with these stains demonstrating resistance to multiple antibiotics following in vivo exposure to MDR EC. However, serogrouping and serotyping results from a portion of the Salmonella isolates recovered from the calves post-challenge, identified two new strains of Salmonella; therefore transfer of resistance was not demonstrated under these experimental conditions.

Flow cytometry was used to obtain genome sizes for 11 species in three genera of Caricaceae to determine if genome size differences can be detected between sexes. Genome sizes ranged from 442.5 to 625.9 megabases (Mb) likely due to variation in the accumulation of retrotransposons in the genomes. The C. papaya genome size was estimated to be 442.5 Mb, larger than previously reported. Significant differences were detected between male and female samples in Jacaratia spinosa, Vasconcellea horovitziana, and V. stipulata, and between male and hermaphrodite samples of V. cundinamarcensis, suggesting the presence of sex chromosomes for these species. The small size differences between genomes of the papaya sexes were not detected using flow cytometry. Vasconcellea horovitziana was discovered to have a larger female genome size than male, suggesting the possibility of a ZW sex chromosome system in the family. The estimated genome sizes of these 11 species will be used in sequencing their genomes and in sex chromosome research for this family.

This special issue includes eleven studies on adventive and invasive Acari species affecting major crops and livestock around the world. The nucleus for this special issue is formed by the presentations in the symposium on invasive mites and ticks organized at the International Congress of Acarology in Recife, Brazil (ICA-13), in the summer of 2010. This special issue illustrates the increased concerns about domestic and international invasive mites and ticks worldwide.

Up to 104 phytophagous species have been reported causing damage to leaves, buds and fruits, but only a dozen can be considered major pests requiring control measures. In recent years, several species have expanded their geographical range primarily due to the great increase in trade and travel worldwide, representing a threat to agriculture in many countries. Three spider mite species (Acari: Tetranychidae) have recently invaded the citrus-growing areas in the Mediterranean region and Latin America. The Oriental red mite, Eutetranychus orientalis (Klein), presumably from the Near East, was detected in southern Spain in 2001. The Texas citrus mite, Eutetranychus banksi (McGregor), is widely distributed in North, Central and South America. It was first reported in Europe in 1999 on citrus in Portugal; afterwards the mite invaded the citrus orchards in southern Spain. In Latin America, the Hindustan citrus mite, Schizotetranychus hindustanicus (Hirst), previously known only from citrus and other host plants in India, was reported causing significant damage to citrus leaves and fruits in Zulia, northwest Venezuela, in the late 1990s. Later, this mite species spread to the southeast being detected on lemon trees in the state of Roraima in northern Brazil in 2008. Whereas damage levels, population dynamics and control measures are relatively well know in the case of Oriental red mite and Texas citrus mite, our knowledge of S. hindustanicus is noticeably scant. In the present paper, information on pest status, seasonal trends and natural enemies in invaded areas is provided for these species, together with morphological data useful for identification. Because invasive species may evolve during the invasion process, comparison of behavior, damage and management options between native and invaded areas for these species will be useful for understanding the invader's success and their ability to colonize new regions.

TI Travelling with tea: a Tuckerella's tale SO EXPERIMENTAL AND APPLIED ACAROLOGY LA English DT Article DE Low temperature scanning electron microscopy; Quarantine; Taxonomy; Tetranychoidea; Tuckerellidae ID CONSUMPTION; CHEMISTRY; CANCER; ACARI AB Tuckerella japonica Ehara appears strongly associated with tea (Camellia sinensis (L.) Kuntze, Theaceae) and, due to certain cultural practices in tea production, has in fact become a world traveller, accompanying the greatly coveted tea plant as it spread across the planet. The history of tea production and culture, and its arrival in the USA, provides the backdrop for this traveller's tale. Tuckerella japonica is morphologically similar to T. flabellifera Miller, described from Tasmania in Australia from Bedfordia salicina (Labill.) D.G. (Asteraceae). These two species have historically been misidentified as each other, creating inaccuracies in the collection records. The implications of this in terms of host plant lists and world distribution are discussed further, along with their morphological separation. The male and immature stages of T. japonica are described for the first time. Tuckerella xinglongensis Lin and Fu, from tea in China, is considered a junior synonym of T. japonica. The loss of the ancestral prostigmatan condition of three nymphal stages during ontogeny is confirmed for males of T. flabellifera, which do not retain a tritonymphal stage. C1 [Beard, J.

Crude almond protein extracts were treated with PUV (3 pulses/s, 10 cm from lamp) for 0.5, 1, 2, 3, 4, 6, 7, and 10 min. In comparison, boiling treatments were also carried out. The HHP treatments were conducted at 600 MPa for 5, 15, and 30 min at three temperatures of 4 A degrees C, 21 A degrees C, and 70 A degrees C. Western blots and indirect ELISA demonstrated a reduction in the levels of allergens and IgE binding in PUV-treated extracts at 7 min, which was found to be the optimal time for PUV exposure. Boiling was not as effective as PUV in reducing the overall IgE-binding of the almond extracts. Unlike PUV, HHP did not affect the allergen levels and IgE binding under the conditions tested.

Methods and Results Barrows (n = 160) were sorted into two treatments at 10 weeks of age (week 0 of the study), and fed growing, grow finishing and finishing diets in 4-week feeding periods. For each feeding phase, diets were prepared without (A-) and with (A+) dietary antimicrobials (chlortetracycline, 08 week; bacitracin, 912 week) typical of the United States. At week 0, 4, 8, 9, 10 and 12 of the study, faecal swabs or grabs were collected for analyses. Campylobacter spp. was absent at week 0, but prevalence increased over time with most isolates being identified as Campylobacter coli. When chlortetracycline was used in A+ diets (week 4 and 8), prevalence for Campylobacter spp., pathogenic Escherichia coli O26 and stx genes was lower in faeces. On week 12 after the shift to bacitracin, Campylobacter spp. and stx genes were higher in faeces from piglets fed A+ diet. Pathogenic E. coli serogroups O103 and O145 were isolated throughout the study and their prevalence did not differ due to diet. Pathogenic E. coli serogroups O111 and O121 were never found in the piglets, and Salmonella spp. prevalence was low. Conclusions In production swine, growing diets with chlortetracycline may have reduced pathogen shedding compared with the A-growing diets, whereas finishing diets with bacitracin may have increased pathogen shedding compared with the A-finishing diet. Significance and Impact of the Study Inclusion of antimicrobials in the diet can affect zoonotic pathogen shedding in faeces of swine. C1 [Wells, J. E.; Kalchayanand, N.; Berry, E. D.; Oliver, W.

TI Characteristics and use of the Illumina BovineLD and GeneSeek Genomic Profiler low-density bead chips for genomic evaluation SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE bead chip; BovineLD; GeneSeek Genomic Profiler; genomic evaluation ID GENOTYPES AB The GeneSeek Genomic Profiler (GGP) BeadChip (GeneSeek, Lincoln, NE), which became available commercially in February 2012, is based on the Illumina BovineLD Genotyping BeadChip (Illumina Inc., San Diego, CA), with 1,745 additional single nucleotide polymorphisms (SNP) for genomic evaluation and SNP for proprietary single-gene tests. The BovineLD chip with 6,909 SNP, which replaced the Illumina GoldenGate Bovine3K Genotyping BeadChip, has been available since October 2011. The GGP's additional SNP for genomic evaluation were selected to improve imputation by filling SNP gaps on chromosomes and including more Bovine3K SNP than were on the BovineLD chip and to impute microsatellite alleles to facilitate parentage validation. The SNP for single-gene tests were included to minimize the number of separate tests required for those genes, particularly for bulls. The September 2012 US national genomic evaluation included genotypes from BovineLD and GGP chips for 82,510 animals. For those data, BovineLD and GGP performance was similar. The call rate for SNP on these chips that were used in genomic evaluation was 99.6%. The 9 Y-chromosome SNP in common on the BovineLD and GGP chips were highly effective in sex validation (call rate of 99% for males and 0.01% for females). For both chips, the rate of parent-progeny conflicts on a SNP basis (<= 0.004%) was similar to that for SNP on the Illumina BovineSNP50 Genotyping BeadChip. Imputation accuracy for 45,187 BovineSNP50 SNP averaged 99.4% for Holsteins. Imputation accuracy was slightly higher for the GGP chip compared with the BovineLD chip because of its additional SNP. Reliability for genomic evaluations using BovineLD and GGP genotypes was 3 percentage points higher than that for Bovine3K genotypes. C1 [Wiggans, G. R.; Cooper, T.

TI Changes to herd cutoff date in conception rate evaluations SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE conception rate; fertility; evaluation ID HOLSTEINS AB Service-sire conception rate (SCR) evaluations were implemented for the United States in August 2008. Only inseminations from the most recent 4 yr of breeding records are used for SCR evaluations, and all inseminations must have occurred >= 70 d before the data submission deadline for an evaluation. In April 2012, edits for SCR were modified so that all inseminations must have occurred >= 70 d before the last herd test date rather than the constant date of 70 d before the data submission deadline. This edit more precisely measures the days of opportunity for a cow to be diagnosed as pregnant or not pregnant following insemination, and is herd specific. The number of inseminations before the edit change was 16,906,385 compared with 16,492,331 after the edit change. Correlations of SCR before and after the edit change were 0.96 for Holsteins and slightly lower for other breeds, with little change in mean or standard deviation. Weekly mean conception rates after the edit change were more stable for the most recent inseminations. The conception rate was 60% at wk 10 before the constant cutoff date (before edit change) compared with 42% at 10 wk before the last herd test date (after the edit change). Similar edits to SCR are applied to heifer conception rate (HCR) and cow conception rate data (CCR), and were changed in August 2012 to use herd-specific cutoff dates. The HCR and CCR correlations before and after the edit change were 0.99 or higher for all breeds, with little change in mean or standard deviation. The new edits improve accuracy of SCR, HCR, and CCR evaluations by accounting for differing opportunity to confirm pregnancy caused by discontinued testing or differences in herd testing schedules.

Since then, multiple articles have investigated avermectins' degradation and its efficacy against a wide variety of pests under different conditions and using different modes of application. However, there is a gap in the literature of analysing abamectin properties and its performance as a non-fumigant nematicide when applied liquid or granular vs. new avenues of application based on seed and seedling treatment. Therefore, this article reviewed literature to discuss the mode of action, environmental aspects, the nematicidal effectiveness of treatment forms and the range of activity to address these topics.

Agricultural weeds have repeatedly been selected for weed-adaptive traits such as rapid growth, increased seed dispersal and dormancy, thus providing an ideal system for the study of convergent evolution. Here, we identify QTL underlying weedy traits and compare their genetic architecture to assess the potential for convergent genetic evolution in two distinct populations of weedy rice. F2 offspring from crosses between an indica cultivar and two individuals from genetically differentiated U.S. weedy rice populations were used to map QTL for four quantitative (heading date, seed shattering, plant height and growth rate) and two qualitative traits. We identified QTL on nine of the twelve rice chromosomes, yet most QTL locations do not overlap between the two populations. Shared QTL among weed groups were only seen for heading date, a trait for which weedy groups have diverged from their cultivated ancestors and from each other. Sharing of some QTL with wild rice also suggests a possible role in weed evolution for genes under selection during domestication. The lack of overlapping QTL for the remaining traits suggests that, despite a close evolutionary relationship, weedy rice groups have adapted to the same agricultural environment through different genetic mechanisms.

However, sensor calibration is difficult early in the growing season when crops are rapidly growing. Studies were conducted in the United States and Mexico to evaluate procedures to determine the vegetation index of adequately fertilized plants in producer fields without establishing a nitrogen-rich reference area. The virtual-reference concept uses a histogram to characterize and display the sensor data from which the vegetation index of adequately fertilized plants can be identified. Corn in Mexico at the five-leaf growth stage was used to evaluate opportunities for variable rate N fertilizer application using conventional tractor-based equipment. A field in Nebraska, USA at the twelve-leaf growth stage was used to compare data interpretation strategies using: (1) the conventional virtual reference concept where the vegetation index of adequately fertilized plants was determined before N application was initiated; and (2) a drive-and-apply approach (no prior canopy sensor information for the field before initiating fertilizer application) where the fertilizer flow-rate control system continuously updates a histogram and automatically calculates the vegetation index of adequately fertilized plants. The 95-percentile value from a vegetation-index histogram was used to determine the vegetation index of adequately fertilized plants. This value was used to calculate a sufficiency index value for other plants in the fields. The vegetation index of reference plants analyzed using an N-rich approach was 3-5 % lower than derived using the virtual-reference concept. C1 [Holland, Kyle H.] Holland Sci, Lincoln, NE USA.

Marker-assisted selection combined with conventional breeding is one powerful approach to improve cacao resistance to Ceratocystis wilt. In this study we screened a set of ESTs obtained from cacao elicited with C. cacaofunesta to identify EST-SSRs and test their efficacy for mapping. Among the 3,432 ESTs analysed, 384 contained SSRs and 428 EST-SSRs were identified, mainly dinucleotides (78.5 %), with four repeats (75.23 %), and preferentially AG/CT motif (25.47 %). Gene ontology function was assigned to the ESTs containing SSRs: 4.04 % belonged to "defense response" category, with 20.69 % of them to the sub-category "defense response to fungi". In relation to the ORF, the same quantity of EST-SSRs was observed in the 5' UTR, ORF and the 3' UTR (about 30 %). From the 428 EST-SSRs identified, 12 were polymorphic, revealing a total of 41 alleles. The number of alleles per locus ranged from 2 to 6, with an average of 3.41. Four EST-SSRs were mapped on the F-2 Sca 6 x ICS 1 population segregating for Ceratocystis wilt, and were distributed on the 2, 3, 4 and 8 linkage groups. These markers will have potential applications in linkage mapping and will be valuable for the research community to improve the cacao breeding program.

Despite the economic interest in Juglans x intermedia (J. nigra x J. regia), walnut hybridization is rare under natural conditions and still difficult using controlled pollination. Here, we evaluated some reproductive mechanisms that may prevent successful natural hybridization. The study of flowering phenology of 11 J. nigra and 50 J. regia trees growing in a plantation provided information regarding the opportunity for interspecific crosses. Variation in flower size, pollen quality of putative donors, and variation in seed yield and rate of hybrid production among putative maternal trees were examined. DNA fingerprinting and parentage analyses based on nine microsatellites permitted the identification of hybrids and hybridogenic parent. Our data indicated that overlap occurred between the staminate flowering of protogynous J. regia and the beginning of pistillate flowering of protogynous J. nigra. Differences in floral size were computed between walnut species. Only three hybrids among 422 offspring of eleven J. nigra progenies were identified. Interspecific hybridization involving pollination of one early-flowering-protogynous J. nigra by three protogynous J. regia trees was detected. The correct development of J. regia male gametophytes, high pollen viability (86.5 %), and germination (57.6 %) ruled out the possibility that low pollen quality contributed to depressed hybrid production. Our findings indicated that these two species tended to remain reproductively isolated. The substantial disjunction in flowering time and additional prezygotic barriers such as differences in floral size and conspecific pollen advance may affect interspecific gene flow between J. regia and J. nigra.

Early detection of potentially high-risk pathogens within animal hosts may facilitate medical interventions to cope with an emerging disease. To effectively spillover to a novel host, a pathogen may undergo genetic changes resulting in varying transmission potential in the new host and potentially to humans. Rabies virus (RABV) is one model pathogen to consider for studying the dynamics of emerging infectious diseases under both laboratory and field conditions. The evolutionary history of RABV is characterized by regularly documented spillover infections and a series of notable host shifts. Within this context, enhanced field surveillance to improve detection of spillover infections will require validated techniques to non-invasively differentiate infected from non-infected individuals. In this study, we evaluate the use of infrared thermography to detect thermal changes associated with experimental RABV infection in big brown bats (Eptesicus fuscus) in a captive colony. Our results indicated that 62% of rabid bats had detectable facial temperature decreases (-4.6 degrees C, SD +/- 2.5) compared with pre-inoculation baseline values. These data suggest potential utility for discriminating rabid bats in natural field settings. In addition, focusing upon RABV circulating in the United States between 2008 and 2011, we confirmed spillover events of bat RABV among carnivores and identified cross-species transmission events caused by four lineages of RABV associated with insectivorous bats. Additionally, our analysis of RABV glycoprotein sequences identified substitutions in antigenic sites that may affect neutralizing activity associated with monoclonal antibodies proposed for use in human post-exposure prophylaxis. This study provides a glimpse into RABV pathobiology and spillover dynamics among and between bats and a variety of mesocarnivores. C1 [Ellison, J. A.; Kuzmina, N.; Gilbert, A.; Carson, W.

This allowed comparisons between the methods and closer connectivity to experimental measurement techniques. A reactive force field was used that explicitly describes hydrogen bond, coulombic and van der Waals interactions, allowing each contribution to the inter- and intra-molecular forces to be analyzed as a function of crystallographic direction. The uniform deformation studies showed that the forces dominating elastic behavior differed in the axial and transverse directions because of the relationship between the direction of the applied strain and the hydrogen bonding planes. Simulations of nanoscale indentation were then introduced to model the interaction between a hemispherical indenter with the surface of a cellulose I beta rod. The role of indenter size, loading force and indentation speed on the transverse elastic modulus was studied and, for optimized parameters, the results found to be in good agreement with experimentally-measured transverse elastic modulus for individual cellulose crystals.

CNF films were prepared using a pressurized filtration method in combination with freeze drying. The freeze-dried films were swollen with water then impregnated with PF resin by soaking in aqueous resin solutions of varying concentrations. Small amounts of PF slightly enhanced the tensile properties of CNF films. The formulation with the best mechanical properties was CNF/PF films with 8 wt % resin exhibiting tensile stress and toughness of 248 MPa and 26 MJ/m(3), respectively. Resin concentrations higher than about 8 % resulted in composites with decreased tensile properties as compared to neat CNF films. The wet strength of the composite films was significantly higher than that of the neat CNF films. The resulting composites showed greater resistance to moisture absorption accompanied by reduced thickness swelling when soaked in water as compared to neat CNF films. The composites also showed decreased oxygen permeability at low humidity compared to neat films, but the composites did not show improved barrier properties at high humidity.

The Mercury software was used, and different crystallite sizes were based on different input peak widths at half of the maximum peak intensity (pwhm). The two cellulose polymorphs, I beta and II, gave different CIs despite having the same pwhm values and perfect periodicity. The higher CIs for cellulose II were attributed to a greater distance between the major peaks that are closest to the recommended 2-theta value for assessing the amorphous content. That results in less peak overlap at the recommended 2-theta value. Patterns calculated with simulated preferred orientation had somewhat higher CIs for cellulose I beta, whereas there was very little effect on the CIs for cellulose II.

Amplification of 16S rRNA genes was done using DNA extracted from 30 soil samples (three treatments x two horizons x five subplots) collected from untreated (control), low N-amended (50 kg ha-1 year-1) and high N-amended (150 kg ha-1 year-1) plots. A total of 1.3 million sequences were processed using qiime. Although Acidobacteria represented the most abundant phylum based on the number of sequences, Proteobacteria were the most diverse in terms of operational taxonomic units (OTUs). UniFrac analyses revealed that the bacterial communities differed significantly among soil horizons and treatments. Microsite variability among the five subplots was also evident. Nonmetric multidimensional scaling ordination of normalized OTU data followed by permutational manova further confirmed these observations. Richness indicators and indicator species analyses revealed higher bacterial diversity associated with N amendment. Differences in bacterial diversity and community composition associated with the N treatments were also observed at lower phylogenetic levels. Only 2835% of the 6 936 total OTUs identified were common to three treatments, while the rest were specific to one treatment or common to two.

Two important characteristics of starch are amylose/amylopectin ratio and molecular weight. The objective of this study was to develop a simple, one-step, and accurate method for the determination of amylose/amylopectin ratio and weight-averaged molecular weights of starch in whole meal cereal samples. This method would allow for the simultaneous measurement of these important properties without the time-consuming step of large-scale starch extraction. Starch from spring wheat, barley, oat, rye, buckwheat, rice, durum wheat, and corn was precipitated with ethanol and solubilized with potassium hydroxide and urea before analysis by a high-performance size exclusion chromatography (HPSEC) system with a refractive index detector. To verify peak identity, fractions were collected and then gas chromatography analysis of soluble starch and beta-glucan assays was performed. All HPSEC fractions contained only glucose and no beta-glucan was detected, indicating that there was no contamination from non-starch polysaccharides. Weight-averaged molecular weights were calculated using a series of gel permeation chromatography grade dextrans. The method described in this study can be used to determine amylose/amylopectin ratio and weight-averaged molecular weight of cereal starches using as low as 25 mg whole meal samples without large-scale starch extraction.

TI Spatial regression methods capture prediction uncertainty in species distribution model projections through time SO GLOBAL ECOLOGY AND BIOGEOGRAPHY LA English DT Article DE California; climate change; conservation planning; GLM; GLMM; historic data; species distribution models; transferability; uncertainty ID CLIMATE-CHANGE; EXTINCTION RISK; UNITED-STATES; CONSERVATION; SPACE; AUTOCORRELATION; CALIFORNIA; DATASETS; FUTURE; RULES AB Aim The uncertainty associated with species distribution model (SDM) projections is poorly characterized, despite its potential value to decision makers. Error estimates from most modelling techniques have been shown to be biased due to their failure to account for spatial autocorrelation (SAC) of residual error. Generalized linear mixed models (GLMM) have the ability to account for SAC through the inclusion of a spatially structured random intercept, interpreted to account for the effect of missing predictors. This framework promises a more realistic characterization of parameter and prediction uncertainty. Our aim is to assess the ability of GLMMs and a conventional SDM approach, generalized linear models (GLM), to produce accurate projections and estimates of prediction uncertainty. Innovation We employ a unique historical dataset to assess the accuracy of projections and uncertainty estimates from GLMMs and GLMs. Models were trained using historical (19281940) observations for 99 woody plant species in California, USA, and assessed using temporally independent validation data (20002005). Main conclusions GLMMs provided a closer fit to historic data, had fewer significant covariates, were better able to eliminate spatial autocorrelation of residual error, and had larger credible intervals for projections than GLMs. The accuracy of projections was similar between methods but GLMMs better quantified projection uncertainty. Additionally, GLMMs produced more conservative estimates of species range size and range size change than GLMs. We conclude that the GLMM error structure allows for a more realistic characterization of SDM uncertainty. This is critical for conservation applications that rely on honest assessments of projection uncertainty.

TI Modified method for combined DNA and RNA isolation from peanut and other oil seeds SO MOLECULAR BIOLOGY REPORTS LA English DT Article DE RNA; DNA; Isolation; Peanut; Oil seeds ID STARCH AB Isolation of good quality RNA and DNA from seeds is difficult due to high levels of polysaccharides, polyphenols, and lipids that can degrade or co-precipitate with nucleic acids. Standard RNA extraction methods utilizing guanidinium-phenol-chloroform extraction has not shown to be successful. RNA isolation from plant seeds is a prerequisite for many seed specific gene expression studies and DNA is necessary in marker-assisted selection and other genetic studies. We describe a modified method to isolate both RNA and DNA from the same seed tissue and have been successful with several oil seeds including peanut, soybean, sunflower, canola, and oil radish. An additional LiCl precipitation step was added to isolate both RNA and DNA from the same seed tissues. High quality nucleic acids were observed based on A(260)/A(280) and A(260)/A(230) ratios above 2.0 and distinct bands on gel-electrophoresis. RNA was shown to be suitable for reverse transcriptase polymerase chain reaction based on actin or 60S ribosomal primer amplification and DNA was shown to have a single band on gel-electrophoresis analysis. This result shows that RNA and DNA isolated using this method can be appropriate for molecular studies in peanut and other oil containing seeds.

TI Root stress and nitrogen deposition: consequences and research priorities SO NEW PHYTOLOGIST LA English DT Article DE allocation; aluminum (Al); drought; model; nitrogen deposition; root biogeochemical stress; root lifespan; threshold ID DISEASE RESISTANCE RESPONSE; NORTHERN HARDWOOD FORESTS; FINE ROOTS; BIOMASS ALLOCATION; PLANT NUTRITION; GLOBAL CHANGE; N DEPOSITION; OAK FOREST; SATURATION; ECOSYSTEMS AB Stress within tree roots may influence whole-tree responses to nutrient deficiencies or toxic ion accumulation, but the mechanisms that govern root responses to the belowground chemical environment are poorly quantified. Currently, root production is modeled using rates of forest production and stoichiometry, but this approach alone may be insufficient to forecast variability in forest responses when physical and chemical stressors alter root lifespan, rooting depth or mycorrhizal colonization directly. Here, we review key research priorities for improving predictions of tree responses to changes in the belowground biogeochemical environment resulting from nitrogen deposition, including: limits of the optimum allocation paradigm, root physiological stress and lifespan, contingency effects that determine threshold responses across broad gradients, coupled water-biogeochemical interactions on roots, mycorrhizal dynamics that mediate root resilience and model frameworks to better simulate root feedbacks to aboveground function. We conclude that models incorporating physiological feedbacks, dynamic responses to coupled stressors, mycorrhizal interactions, and which challenge widely-accepted notions of optimum allocation, can elucidate potential thresholds of tree responses to biogeochemical stressors. Emphasis on comparative studies across species and environmental gradients, and which incorporates insights at the cellular and ecosystem level, is critical for forecasting whole-tree responses to altered biogeochemical landscapes.

We monitored stemwood nonstructural carbohydrate (starch and sugars) concentrations of the dominant tree species at three sites in the northeastern United States. We estimated the mean age of the starch and sugars in a subset of trees using the radiocarbon (14C) bomb spike. With these data, we then tested different carbon (C) allocation schemes in a process-based model of forest C cycling. We found that the nonstructural carbohydrates are both highly dynamic and about a decade old. Seasonal dynamics in starch (two to four times higher in the growing season, lower in the dormant season) mirrored those of sugars. Radiocarbon-based estimates indicated that the mean age of the starch and sugars in red maple (Acer rubrum) was 714 similar to yr. A two-pool (fast and slow cycling reserves) model structure gave reasonable estimates of the size and mean residence time of the total NSC pool, and greatly improved model predictions of interannual variability in woody biomass increment, compared with zero- or one-pool structures used in the majority of existing models. This highlights the importance of nonstructural carbohydrates in the context of forest ecosystem carbon cycling.

Populations of A. canescens from different habitats of the Chihuahuan Desert (New Mexico, USA) were analyzed using flow cytometry to determine ploidy levels. Traits related to xylem water transport efficiency and safety against drought-induced hydraulic failure were measured in both stems and leaves. At the stem level, cytotypes of higher ploidy showed consistently lower leaf-specific hydraulic conductivity but greater resistance to drought-induced loss of hydraulic conductivity. At the leaf level, comparisons in hydraulics between cytotypes did not show a consistent pattern, but exhibited high plasticity to proximal environmental conditions related to soil water availability. The results suggest that a trade-off between stem hydraulic efficiency and safety across ploidy levels underlies niche differentiation among different cytotypes of A. canescens. Polyploidization may have been facilitated by environmental heterogeneity related to water availability, and variation in water-related physiology found in the present study suggests an important functional basis for the niche differentiation and coexistence of A. canescens cytotypes in desert environments.

In total, 133 isolates of P. triticina collected from western Europe, central Europe and Turkey were tested for virulence on 20 lines of wheat with single leaf rust resistance genes, and for molecular genotypes with 23 simple sequence repeat (SSR) markers. After removal of isolates with identical virulence and SSR genotype within countries, 121 isolates were retained for further analysis. Isolates were grouped based on SSR genotypes using a Bayesian approach and a genetic distance method. Both methods optimally placed the isolates into eight European (EU) groups of P. triticina SSR genotypes. Seven of the groups had virulence characteristics of isolates collected from common hexaploid wheat, and one of the groups had virulence characteristics of isolates from tetraploid durum wheat. There was a significant correlation between the SSR genotypes and virulence phenotypes of the isolates. All EU groups had observed values of heterozygosity greater than expected and significant fixation values, which indicated the clonal reproduction of urediniospores in the overall population. Linkage disequilibria for SSR genotypes were high across the entire population and within countries. The overall values of RST and FST were lower when isolates were grouped by country, which indicated the migration of isolates within Europe. The European population of P. triticina had higher levels of genetic differentiation compared to other continental populations. C1 [Kolmer, J. A.] USDA ARS, Cereal Dis Lab, St Paul, MN 55108 USA.

The genetic population structure of P. graminis f. sp. avenae in Sweden was investigated by sampling 10 oat fields in July and August 2008 and seven fields during the same period in 2009. Nine single-pustule isolates were first used to test simple sequence repeat (SSR) markers developed for P. graminis f. sp. tritici. Eleven of the 68 tested SSR markers were useful for genotyping P. graminis f. sp. avenae. For the main study, DNA from single uredinia was extracted and the SSR markers were used to genotype 472 samples. Both allelic and genotypic diversity were high in all fields, indicating that P. graminis f. sp. avenae undergoes regular sexual reproduction in Sweden. No significant relationship between genetic and geographic distances was found. Disease development was studied on two farms during 2008 and 2009. The apparent infection rates ranged between 0.17 and 0.55, indicating the potential for rapid disease development within fields. The incidence of oat stem rust has increased recently in Sweden. One possible explanation is a resurgence of its alternate host, barberry (Berberis spp.), after the repeal of the barberry eradication law in 1994. Barberry is present in several grain-producing areas in Sweden, which supports the conclusion that P. graminis f. sp. avenae undergoes regular sexual reproduction there.

TI Genomic analysis and secondary metabolite production in Bacillus amyloliquefaciens AS 43.3: A biocontrol antagonist of Fusarium head blight SO BIOLOGICAL CONTROL LA English DT Article DE Bacillus amyloliquefaciens; Genome; Plantazolicin; Chlorotetaine; Bacilysin ID BIOLOGICAL-CONTROL; ITURIN-A; POLYKETIDE BIOSYNTHESIS; NONRIBOSOMAL SYNTHESIS; PEPTIDE ANTIBIOTICS; GIBBERELLA-ZEAE; GENE-CLUSTER; SUBTILIS; SEQUENCE; STRAIN AB The complete genome of the biocontrol antagonist Bacillus amyloliquefaciens AS 43.3 is reported. B. amyloliquefaciens AS 43.3 has previously been shown to be effective in reducing Fusarium head blight in wheat. The 3.9 Mbp genome was sequenced, assembled, and annotated. Genomic analysis of the strain identified 9 biosynthetic gene clusters encoding secondary metabolites associated with biocontrol activity. The analysis identified five non-ribosomal peptide synthetase clusters encoding three lipopeptides (surfactin, iturin, and fengycin), a siderophore (bacillibactin), and the antibiotic dipeptide bacilysin. In addition, three polyketide synthetase clusters were identified which encoded for the antibacterials: bacillaene, difficidin, and macrolactin. In addition to the non-ribosomal mediated biosynthetic clusters discovered, we identified a ribosomally encoded biosynthetic cluster that produces the antibiotic plantazolicin. To confirm the gene clusters were functional, cell-free culture supernatant was analyzed using LC-MS/MS. The technique confirmed the presence of all nine metabolites or their derivatives. The study suggests the strain is most likely a member of the B. amyloliquefaciens subsp. plantarium clade. Comparative genomics of eight completed genomes of B. amyloliquefaciens identify the core and pan-genomes for the species, including identifying genes unique to the biocontrol strains. This study demonstrates the growing importance of applying genomic-based studies to biocontrol organisms of plant pathogens which can enable the rapid identification of bioactive metabolites produced by a prospective biological control organism. In addition, this work provides a foundation for a mechanistic understanding of the B. amyloliquefaciens AS 43.3/Fusarium head blight biocontrol interaction. Published by Elsevier Inc.

However, it is one of the worst wetland invaders in North American wetlands. The native North American status has been supported by the circumstantial evidence of early botanical records and the dating and location of herbarium specimens. The lack of empirical evidence has left the North American native status of the species in doubt and prevented comparisons between native North American and Eurasian populations of the species. We utilized genetic markers to compare a wide range of European and Asian collections to DNA extracted from 38 early North American herbarium specimens. The genetic data confirm the presence of a distinct population present throughout North America in the early twentieth century, but not present in Europe or Asia, ranging from Alaska, USA to New Brunswick, Canada. These native North American populations of reed canarygrass are likely present throughout Alaska today, as one specimen was collected as recently as 1996, and may still be present in other regions of North America. Future research can utilize this dataset to determine the origin of present-day invasive populations in North American wetlands.

These advantages have been characterized in systems in which the invading species has already become well established. Surprisingly, invader impacts on native communities currently undergoing invasion are lacking from most ecological studies. In this work we document and quantify shifting patterns in plant community structure in a native ecosystem (remnant tallgrass prairie) undergoing invasion by the invasive exotic Sorghum halepense (Johnsongrass). Further, we use manipulative field and greenhouse studies to quantify impacts of potential allelochemicals contained in whole-plant S. halepense leachates on growth of the dominant native grass, Schizachyrium scoparium (Little Bluestem), and tested the inhibitory effects of the potential soil legacy of S. halepense on the native grass in the greenhouse. Plant diversity indices revealed three distinct plant communities within the remnant prairie: a native community, a densely S. halepense invaded area, and a transitional zone between the two. Dominance of the native grass, determined by relative percent cover, significantly declined with increased S. halepense invasion via rhizomatous growth. Annual global positioning system monitoring of the S. halepense invasion front was used to quantify advancement into native prairie, documented at an average rate of 0.45 m year(-1). In the manipulative field and greenhouse studies, native S. scoparium treated with invasive S. halepense leachate had significantly less biomass and fewer inflorescences than control plants. These findings indicate the prolific clonal growth in conjunction with the plant chemistry of S. halepense play a significant role in displacement of the native grass.

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

L. asiaticus (LAS)] associated with huanglongbing (HLB; citrus greening disease), currently considered the world's most serious disease of citrus. Asian citrus psyllid transmits LAS in a persistent manner and, although the rate of LAS transmission by ACP individuals usually is low, HLB can spread rapidly in a citrus grove and the geographic range of the disease is expanding, threatening citrus industries in new areas. Intensive chemical control of ACP is the primary management strategy currently advocated for HLB, but this strategy is costly, unsustainable, and generally ineffective. The scientific community is searching aggressively for solutions to HLB on many fronts, but it could still be years before solutions are found and implemented. Plant resistance to LAS is one area of research being pursued, whereby traits that confer resistance are identified and incorporated into citrus germplasm through conventional or transgenic methods. It remains to be seen if a solution to HLB can be found that specifically targets ACP, but research on ACP has been stepped up in a number of areas, notably on ACPLASplant interactions, on host plant resistance to ACP, and on molecular methods of silencing ACP genes to induce mortality or to block its ability to transmit HLB-causing bacteria. Advancements in these and other research areas may depend greatly on a better understanding of basic ACP biology and vectorpathogenhost plant interactions at the molecular, cellular, and community levels. Here, we present an updated review of ACP and HLB with an emphasis on the problem in Florida.

K. Koch (Juglandaceae)] foliage: the black pecan aphid, Melanocallis caryaefoliae (Davis), the yellow pecan aphid, Monelliopsis pecanis Bissell, and the blackmargined aphid, Monellia caryella (Fitch) (all Hemiptera: Aphididae). Adults of M. caryaefoliae and both the nymphs and adults of M. pecanis and M. caryella mainly feed on the lower surface of leaves. Nymphs of M. caryaefoliae appear unique by frequently feeding on the upper surface of pecan leaves. This is risky behavior given the environmental hazards (e.g., rain, solar radiation, and dislodgement) associated with the upper surface. Thus, we determined the leaf surface distribution of M. caryaefoliae on trees in an orchard and on pecan seedlings in the laboratory. A pecan orchard survey found all three aphid species and stages predominantly on the lower leaf surface, except for the nymphs of M. caryaefoliae, which were evenly distributed between upper and lower leaf surfaces. This survey also found aphidophagous lacewing (Neuroptera) larvae predominantly on the lower leaf surface, whereas ladybird beetle (Coleoptera: Coccinellidae) larvae were more evenly distributed between upper and lower surfaces. Laboratory experiments using single or multiple pecan aphid species revealed M. caryaefoliae distribution on pecan seedlings similar to orchard data. Nymphal M. caryaefoliae require nearly 2 days to elicit chlorotic feeding lesions on leaves; without these lesions, nymphal development is hindered. The similar distribution of nymphs of M. caryaefoliae on both leaf surfaces likely reflects a strategy of predator avoidance allowing a proportion of the population to survive. C1 [Cottrell, T.

Small growers, with low technological inputs, represent a large portion of cotton growers worldwide comprising more than 76 countries; they rely mainly on cultural practices to counteract pest attack in their crops. Boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae), oviposition involves puncturing cotton squares and young bolls, causing abscission. We examined the impact on boll weevil population of collecting abscised cotton fruiting bodies and clipping plant terminals at 50% boll maturation in the field during two cotton-growing seasons and under field cage conditions. Greatest numbers of damaged squares occurred ca. 117 days after planting and clipped plants resulted in reduction of abscised structures and adult boll weevils compared with non-clipped plants, irrespective of cotton variety. Damaged young bolls were found ca. 128 days after planting in 2009 and 2011, but clipping had no effect. Numbers of boll weevils found in plants of the varieties BRS 201 and BRS Rubi (both in 2009) and BRS Rubi (in 2011) were, respectively, 13-, 17-, and 20-fold greater when clipping plus collecting abscised fruiting bodies were not practiced. Furthermore, the average percentage of the boll weevil parasitoid Bracon vulgaris Ashmead (Hymenoptera: Braconidae) emerging from abscised and collected structures was similar between clipped and non-clipped plant terminals in both seasons. Clipping plant terminals did not result in yield reduction and reduced adult boll weevil production. Collecting abscised reproductive structures, clipping plant terminals, and using both practices together reduced boll weevil populations by as much as 63, 57, and 79%, respectively, in cage trials. Thus, these practices cause significant impact on boll weevil populations and are feasible of adoption, especially for smallholder cotton growers. C1 [Neves, Roberio C.

TI Re-emergence of the Ib mitochondrial haplotype within the British and Irish Phytophthora infestans populations SO EUROPEAN JOURNAL OF PLANT PATHOLOGY LA English DT Article DE Phytophthora infestans; Ib haplotype; Allozyme; RG57 fingerprinting ID POTATO FAMINE PATHOGEN; GENOTYPIC DIVERSITY; PCR AMPLIFICATION; MATING-TYPE; RESISTANCE; METALAXYL; IRELAND; DNA; DISPLACEMENT; SWITZERLAND AB Since its arrival in the British Isles in 1845 Phytophthora infestans has remained the most destructive pathogen of potato. In the ensuing period, the British and Irish P. infestans populations have undergone major displacements following the immigration of novel strains. Here we report the re-emergence of the Ib mitochondrial DNA haplotype in the British and Irish P. infestans populations associated with the 6_A1 genotype. Historically associated with the previously panglobally distributed clonal lineage US-1, the Ib haplotype has not been detected (with the exception of a single isolate in the mid 1990s) in the British or Irish P. infestans populations since the early 1980s. The 6_A1 isolates analysed possessed mtDNA Ib, but were otherwise quite unlike US-1, having the Pep allozyme genotype 96/96 and novel RG57 and SSR fingerprints. These genetic characteristics strongly suggest that the appearance of the 6_A1 genotype in these populations has resulted from migration (possibly after a recombination event elsewhere). This study highlights the advantages of utilising a range of different markers in pathogen monitoring.

Seashore mallow seeds contained 19.3 mass % oil, which after extraction with hexane and pretreatment with catalytic sulfuric acid was converted into methyl esters in 94 mass % yield utilizing homogenous base catalysis. The principal components identified were methyl linoleate (48.9%), palmitate (24.4%) and oleate (18.3%). Fuel properties were characterized and compared to biodiesel standards ASTM D6751 and EN 14214. Also investigated were blends with petrodiesel. Lastly, seashore mallow stems were rich in neutral carbohydrates (51.8 mass %). After simultaneous saccharification and fermentation employing a native Saccharomyces cerevisiae yeast strain, the stems provided ethanol and xylose yields of 104 g/kg and 47.8 g/kg, respectively. Of the four pretreatment methodologies explored, dilute ammonium hydroxide provided the highest yield of sugars. Published by Elsevier Ltd.

Data were collected on two blade designs tested on a wind turbine rated at 1 kW, and there also was a third blade tested on an improved version of the same wind turbine. The 1 kW wind turbines were used for off-grid water pumping. If the 1 kW wind turbines were electrically loaded, the start of blade flutter was delayed from 700 to 900 rpm when the blade length was reduced 9.2%, and no blade flutter occurred when the shorter fiberglass blades were stiffened. However, if there was no electrical load (e.g. offline), the shorter stiffer blades would start to flutter at 1050 rpm. For the 10 kW wind turbine, two blade designs were tested for off-grid water pumping, and a third blade design was tested on a utility grid-tie system. The original blades fluttered when the 10 kW off-grid wind turbine was offline at a rotor speed of 260 rpm, but the second blade design (different airfoil) appeared to never flutter at any rotor speed when offline. For the 10 kW wind turbine, the sound emission of the second blade design was approximately the same as that of the third blade design - both had lower sound emissions than the original blade design. Blade flutter increased the average sound power level on the 1 kW wind turbine 15-20 dB and on the 10 kW wind turbine 5-7 dB. A procedure was developed which allowed the best blade design for sound emission to be identified even though the microphone measurement position varied (due to different tower heights) and electrical loading was different (on-grid, off-grid, or offline). This paper should be of help to design engineers interested in designing wind turbines with a lower sound emission, and test engineers collecting and analyzing sound level data of existing wind turbines. This paper may also help in the validation of computer codes that are used to predict whether blade flutter will occur on large MW size wind turbines. Published by Elsevier Ltd.

Oxalate and its precursors (isocitrate and citrate) accumulated in leaves of R. obtusifolius after the Al3+ treatment at pH 4.5. Such increase was not observed under the acidic condition (pH 4.5) without Al3+. Principal component analysis showed organ-specific changes in metabolite levels in R. obtusifolius by the Al3+ treatment. Highly positive correlations between oxalate and its precursors were revealed by hierarchical clustering and correlation analyses. An increase in oxalate content was consistently observed for three Rumex species (R. obtusifolius, R. crispus and R. japonicus) grown in the presence of Al3+. On the other hand, multivariate analyses revealed the differential alterations of other metabolite levels between R. obtusifolius and the other two Rumex species.

However, valid methods for measuring children's TV viewing are sparse and few studies have included Latinos, a population disproportionately affected by obesity. The goal of this study was to test the reliability and convergent validity of four TV viewing measures among low-income Latino preschool children in the United States. Methods: Latino children (n = 96) ages 3-5 years old were recruited from four Head Start centers in Houston, Texas (January, 2009, to June, 2010). TV viewing was measured concurrently over 7 days by four methods: (1) TV diaries (parent reported), (2) sedentary time (accelerometry), (3) TV Allowance (an electronic TV power meter), and (4) Ecological Momentary Assessment (EMA) on personal digital assistants (parent reported). This 7-day procedure was repeated 3-4 weeks later. Test-retest reliability was determined by intraclass correlations (ICC). Spearman correlations (due to nonnormal distributions) were used to determine convergent validity compared to the TV diary. Results: The TV diary had the highest test-retest reliability (ICC = 0.82, p < 0.001), followed by the TV Allowance (ICC = 0.69, p < 0.001), EMA (ICC = 0.46, p < 0.001), and accelerometry (ICC = 0.36-0.38, p < 0.01). The TV Allowance (r = 0.45-0.55, p < 0.001) and EMA (r = 0.47-0.51, p < 0.001) methods were significantly correlated with TV diaries. Accelerometer-determined sedentary minutes were not correlated with TV diaries. The TV Allowance and EMA methods were significantly correlated with each other (r = 0.48-0.53, p < 0.001). Conclusions: The TV diary is feasible and is the most reliable method for measuring US Latino preschool children's TV viewing.

The structure of feedback to the parents on their selection may influence what they learn from the game. Feedback Intervention Theory provides some guidance on the design of such messages. The structure of preferred performance feedback statements has not been investigated within serious videogames. Two feedback formats were tested for a player's preferences within the context of this videogame. Based on Feedback Intervention Theory, which proposes that threat to self-concept impairs feedback response, three-statement (a nonaffirming comment sandwiched between two affirming comments, called "Oreo'' feedback, which should minimize threat to self-concept) and two-statement (a nonaffirming comment followed by an affirming comment) performance feedbacks were tailored to respondents. Tailoring was based on participants' report of frequency of use of effective and ineffective vegetable parenting practices and the reasons for use of the ineffective practices. Participants selected their preference between the two forms of feedback for each of eight ineffective vegetable parenting practices. In general, mothers (n = 81) (no male respondents) slightly preferred the "Oreo'' feedback, but the pattern of preferences varied by demographic characteristics. Stronger relationships by income suggest the feedback structure should be tailored to family income. Future research with larger and more diverse samples needs to test whether perceived threat to self-concept mediates the response to feedback and otherwise verify these findings.

TI Differences in Tolerance of Broccoli and Cabbage Cultivars to Clomazone Herbicide SO HORTTECHNOLOGY LA English DT Article DE cole crops; Brassica oleracea; herbicide tolerance; weed management ID BRASSICA-OLERACEA; WEED-CONTROL AB Clomazone herbicide is registered for cabbage (Brassica oleracea Capitata group) in the United States but not for other crop groups within the species. Greenhouse and field experiments were designed to compare the tolerance of broccoli (B. oleracea Italica group) and cabbage cultivars to clomazone to assess its potential for weed management in broccoli. Four broccoli cultivars (Captain, Green Magic, Legacy, and Patron) and four cabbage cultivars (Bravo, SC 100, Stone Head, and Vantage Point) were evaluated in all experiments. In a greenhouse experiment where seedlings were transplanted into potting medium containing clomazone at 0, 1.0, 2.0, and 4.0 parts per million (ppm), 'Bravo' cabbage was most susceptible. Its injury ratings and shoot weight reduction at 1.0 ppm were similar to ratings and shoot weight reduction for the other cabbage cultivars at 4.0 ppm. Among the broccoli cultivars, Patron was highly susceptible, exhibiting injury and shoot weight reduction similar to Bravo. Green Magic was the most tolerant broccoli cultivar, and it exhibited injury and growth reduction similar to the tolerant cabbage cultivars. In a field experiment where clomazone was applied pre-transplanting at 0.25, 0.5, and 1.0 lb/acre, 0.25 lb/acre caused moderate chlorosis to the susceptible cultivars, Bravo and Patron. At 0.50 and 1.0 lb/acre, most cultivars exhibited chlorosis at 2 weeks after transplanting (WAT); however, tolerant cultivars recovered and injury was often not observed at 6 WAT. At 1.0 lb/acre, chlorosis persisted until maturity on 'Bravo' and 'Patron' foliage. Clomazone did not reduce mean broccoli head weight or the percentage of plants producing market-size heads. Mean cabbage head weight for 'Bravo' was reduced by clomazone at 1.0 lb/acre. This study indicates that the variability in clomazone tolerance among broccoli cultivars may be similar to that among cabbage cultivars and suggests that the herbicide can be used safely on tolerant broccoli cultivars at rates that are recommended for cabbage.

TI Optimal Ripeness Stage for Processing 'Kent' Mangoes into Fresh-cut Slices SO HORTTECHNOLOGY LA English DT Article DE visual quality; compositional quality; aroma volatiles ID QUALITY CHANGES; FRUITS; STORAGE; VEGETABLES; PHYSIOLOGY AB The optimal ripeness stage for processing and marketing fresh-cut mangoes (Mangifera indica 'Kent') with best quality and maximum shelf life was determined. The initial ripeness stage selection was based on whole fruit firmness because this quality attribute was more reliable in predicting fresh-cut shelf life than flesh color or soluble solids content (SSC). Overall, the visual quality deteriorated differently and at different rates among ripeness stages. The shelf life, based on subjective visual evaluation, was 10, 7, and 5 days for ripeness stages corresponding to an average flesh firmness of 35, 30, and 25 N, respectively, and was mainly limited by desiccation and development of off-odor for the two firmer ripeness stages or symptoms of edge tissue damage and spoilage for the least firm stage. The slices from fruit with the highest initial firmness remained firmer during storage, had the lowest pH and SSC to titratable acidity (TA) ratio, and had the highest contents of volatile ketones and esters. The softest slices had the highest pH, SSC:TA ratio, and total ascorbic acid (TAA) content, as well as the lowest TA and highest volatile aldehyde and alcohol contents. Intermediate firmness slices had intermediate pH, SSC:TA ratio, color, and TAA content. Also, they had less volatile alcohols and aldehydes than slices from riper fruit but had similar content of esters as slices from the less ripe fruit. Therefore, based on the results from this study, an initial firmness of 30 N is recommended to process mangoes into fresh-cut slices because it assures the best quality and maximum shelf life based on textural, visual, and compositional attributes.

However, the quality evaluation process, which is dependent on simple size- or color-sorting techniques, is inadequate to meet increased consumer demands for high quality and safety. Among various quality evaluations, detection of cracking defects in cherry tomatoes is a critical process since this type of damage can harbor pathogenic microbes that may have detrimental consequences on consumer health. In this study, a multi-spectral fluorescence imaging technique has been presented as a diagnostic tool for non-destructive detection of defective cherry tomatoes. Fluorescence intensity in the area of cracked cuticle was significantly higher in the blue-green spectral region than that of the sound surfaces, suggesting the multi-spectral fluorescence imaging technique as an effective classification tool for detecting cracking defects on cherry tomatoes. Simple ANOVA classification analysis and principal component analysis were employed to investigate optimal fluorescence wavebands. The results illustrate that a multi-spectral fluorescence image in linear combination with a pair of selected wavebands based on the results of ANOVA analysis was able to detect defective cherry tomatoes with >99% accuracy. The detection algorithm investigated in this study is expected to be used to develop on-site and real-time multi-spectral systems for quality evaluation of cherry tomatoes in postharvest processing plants.

A comprehensive evaluation of plum bacteria for biocontrol activity against Monilinia fructicola, which causes brown rot of stone fruit, is important for determining their biocontrol potential. Resident culturable bacterial microflora of plums from early fruit development until maturity were characterized. The most dominant genera were Curtobacterium (19.88%), Pseudomonas (15.06%), Microbacterium (13.86%), and Clavibacter (12.65%). These genera occurred at all four isolation times and accounted for 61.45% of all isolates. Microbacterium and Curtobacterium dominated at the early stage of fruit development while Pseudomonas and Clavibacter were dominant at the end of the season. Less prevalent genera were Enterobacter (5.42%), Chrysomonas (4.82%), and Pantoea (422%). Most frequently isolated species were Microbacterium lacticum, Clavibacter michiganensis, Curtobacterium flaccumfaciens, Enterobacter intermedius, and Chrysomonas luteola. The seasonal succession of genera was observed in both MANOVA and frequency analysis. Primary and secondary screening of plum-inhabiting bacteria for control of brown rot on wounded fruit resulted in selection of several antagonists among which Pantonea agglomerans and Citrobacter freundii were the most effective. These antagonists grew well in plum wounds and increased by four log units during first three days at 24 degrees C, and two log units after seven days at 4 degrees C. Results indicate that plum microflora are an excellent source of antagonists against brown rot decay originating from wounds after harvest. Published by Elsevier B.V.

The inactivation kinetics of pectin methylesterase (PME) and peroxidase (POD) in the osmodehydrated (OD) jam treated by combined thermal (45-75 degrees C) and high pressure (550-700 MPa) processes were fitted using special cases of first-order kinetics, the fractional conversion and biphasic models and the Weibull distribution function. No complete inactivation was achieved by any combination of temperature and pressure, and 27-40% and 51-70% of PME and POD, respectively, were pressure-stable fractions. Two PME fractions with different pressure stabilities were observed and kinetic models successfully explained that behavior. POD was found to be very baroresistant and only the labile fraction could be inactivated. The extent of enzyme inactivation was lower in the OD jam in comparison with other food matrices showing a protective effect against the high pressure treatment. The antioxidant capacity was not affected by any treatment. The proposed high pressure preservation processing was able to improve the enzymatic stability of jam obtained by osmotic dehydration without affecting the bioactive content.

TI Promotional Competition Between Supermarket Chains SO REVIEW OF INDUSTRIAL ORGANIZATION LA English DT Article DE Competition; Food retailing; Market concentration; Price promotions; Price variation ID SALES; POWER; INDUSTRY; PRICES; CHOICE; BRAND AB This article measures promotional competition between two major supermarket chains in the United States. The approach does not rely upon quantity sales data and can be applied to any industry that features advertised sales. The results indicate that retailers do compete using promotions. A supermarket promotion in one week significantly increases the probability of a promotion for the same product at rival stores in the following week. Additionally, competitors seek to match or exceed the price cuts of their rivals when responding to promotions. Oligopolistic competition plays a significant role in determining the timing of sales and retail price variation. C1 ERS, Food Econ Div, Food Markets Branch, USDA,FED,FM, Washington, DC 20024 USA.

AltMV TGB3 subcellular localization was previously shown to be distinct from that of Potato virus X (PVX) TGB3, and a chloroplast binding domain identified; veinal necrosis and chloroplast vesiculation were observed in Nicotiana benthamiana when AltMV TGB3 was over-expressed from PVX. Plants with over-expressed TGB3 showed more lethal damage under dark conditions than under light. Yeast-two-hybrid analysis and bimolecular fluorescence complementation (BiFC) reveal that Arabidopsis thaliana PsbO1 has strong interactions with TGB3; N. benthamiana PsbO (NbPsbO) also showed obvious interaction signals with TGB3 through BiFC. These results demonstrate an important role for TGB3 in virus cell-to-cell movement and virus-host plant interactions. The Photosystem II oxygen-evolving complex protein PsbO interaction with TGB3 is presumed to have a crucial role in symptom development and lethal damage under dark conditions. In order to further examine interactions between AtPsbO1, NbPsbO, and TGB3, and to identify the binding domain(s) in TGB3 protein, BiFC assays were performed between AtPsbO1 or NbPsbO and various mutants of TGB3. Interactions with C-terminally deleted TGB3 were significantly weaker than those with wild-type TGB3, and both N-terminally deleted TGB3 and a TGB3 mutant previously shown to lose chloroplast interactions failed to interact detectably with PsbO in BiFC. To gain additional information about TGB3 interactions in AltMV-susceptible plants, we cloned 12 natural AltMV TGB3 sequence variants into a PVX expression vector to examine differences in symptom development in N. benthamiana. Symptom differences were observed on PVX over-expression, with all AltMV TGB3 variants showing more severe symptoms than the WT PVX control, but without obvious correlation to sequence differences.

TI Differences in X-Chromosome Transcriptional Activity and Cholesterol Metabolism between Placentae from Swine Breeds from Asian and Western Origins SO PLOS ONE LA English DT Article ID REAL-TIME PCR; GENE-EXPRESSION; OVULATION RATE; LITTER SIZE; XIST RNA; OLIGONUCLEOTIDE ARRAYS; MICROARRAY DATA; MIXED MODELS; PIGS; DNA AB To gain insight into differences in placental physiology between two swine breeds noted for their dissimilar reproductive performance, that is, the Chinese Meishan and white composite (WC), we examined gene expression profiles of placental tissues collected at 25, 45, 65, 85, and 105 days of gestation by microarrays. Using a linear mixed model, a total of 1,595 differentially expressed genes were identified between the two pig breeds using a false-discovery rate q-value <= 0.05. Among these genes, we identified breed-specific isoforms of XIST, a long non-coding RNA responsible X-chromosome dosage compensation in females. Additionally, we explored the interaction of placental gene expression and chromosomal location by DIGMAP and identified three Sus scrofa X chromosomal bands (Xq13, Xq21, Xp11) that represent transcriptionally active clusters that differ between Meishan and WC during placental development. Also, pathway analysis identified fundamental breed differences in placental cholesterol trafficking and its synthesis. Direct measurement of cholesterol confirmed that the cholesterol content was significantly higher in the Meishan versus WC placentae. Taken together, this work identifies key metabolic pathways that differ in the placentae of two swine breeds noted for differences in reproductive prolificacy.

TI Evaluation of Three Field-Based Methods for Quantifying Soil Carbon SO PLOS ONE LA English DT Article ID DIFFUSE-REFLECTANCE SPECTROSCOPY; INDUCED BREAKDOWN SPECTROSCOPY; MITIGATION; AGRICULTURE; STORAGE; LIBS AB Three advanced technologies to measure soil carbon (C) density (g C m(-2)) are deployed in the field and the results compared against those obtained by the dry combustion (DC) method. The advanced methods are: a) Laser Induced Breakdown Spectroscopy (LIBS), b) Diffuse Reflectance Fourier Transform Infrared Spectroscopy (DRIFTS), and c) Inelastic Neutron Scattering (INS). The measurements and soil samples were acquired at Beltsville, MD, USA and at Centro International para el Mejoramiento del Maiz y el Trigo (CIMMYT) at El Batan, Mexico. At Beltsville, soil samples were extracted at three depth intervals (0-5, 5-15, and 15-30 cm) and processed for analysis in the field with the LIBS and DRIFTS instruments. The INS instrument determined soil C density to a depth of 30 cm via scanning and stationary measurements. Subsequently, soil core samples were analyzed in the laboratory for soil bulk density (kg m(-3)), C concentration (g kg(-1)) by DC, and results reported as soil C density (kg m(-2)). Results from each technique were derived independently and contributed to a blind test against results from the reference (DC) method. A similar procedure was employed at CIMMYT in Mexico employing but only with the LIBS and DRIFTS instruments. Following conversion to common units, we found that the LIBS, DRIFTS, and INS results can be compared directly with those obtained by the DC method. The first two methods and the standard DC require soil sampling and need soil bulk density information to convert soil C concentrations to soil C densities while the INS method does not require soil sampling. We conclude that, in comparison with the DC method, the three instruments (a) showed acceptable performances although further work is needed to improve calibration techniques and (b) demonstrated their portability and their capacity to perform under field conditions.

Over a three month period, eight releases, totaling 7,696 females and 3,968 males, were made in a turkeyberry, Solanum torvum Swartz (Solanales: Solanaceae) patch known to have a well established B. latifrons population. The establishment of D. kraussii was assessed through fruit collections conducted over a three-year period beyond the last release. D. kraussii was recovered 2 weeks, 31 months, and 39 months after the last parasitoid release, with collections not only from the release site, but also from a control site about 5.0 km distance from the release site. Recovery from fruit collections three years after the last parasitoid release confirmed that D. kraussii had become established in Hawaii. Parasitism rates were low, only 1.0-1.4%, compared to rates of 2.8-8.7% for the earlier established egg-larval parasitoid, Fopius arisanus (Sonan).

TI Functional responses and prey-stage preferences of a predatory gall midge and two predacious mites with twospotted spider mites, Tetranychus urticae, as host SO JOURNAL OF INSECT SCIENCE LA English DT Article DE Amblyseius swirskii; Feltiella acarisuga; Neoseiulus californicus; predation; vegetable crops ID SWIRSKII ACARI PHYTOSEIIDAE; WESTERN FLOWER THRIPS; BIOLOGICAL-CONTROL; NEOSEIULUS-CALIFORNICUS; AMBLYSEIUS-SWIRSKII; FRANKLINIELLA-OCCIDENTALIS; NATURAL ENEMIES; VALLOT DIPTERA; CECIDOMYIIDAE; PEPPER AB The twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is an important pest of vegetables and other economically important crops. This study evaluated the functional responses and prey-stage preferences of three species of predators, a predatory gall midge, Feltiella acarisuga (Vallot) (Diptera: Cecidomyiidae), and two predatory mite species, Neoseiulus californicus (McGregor) (Acari: Phytoseiidae) and Amblyseius swirskii (Anthias-Henriot), with T. urticae as the host, under laboratory conditions. The results showed that F. acarisuga was highly effective and the two species of predacious mites were moderately effective in feeding on T. urticae eggs. Logistic regression analysis suggested Type II (convex) functional responses for all three species. However, based on the estimates of the handling time and the attacking rates, the three predators had different predation capacities. Among the three species, F. acarisuga had the highest predation on T. urticae. The maximum daily predation by a larval F. acarisuga was 50 eggs/day, followed by a female N. californicus (25.6 eggs/day) and a female A. swirskii (15.1 eggs/day). A female N. californicus produced more eggs than a female A. swirskii did when they both fed on T. urticae eggs. In addition, all three predator species had no prey-stage preference for either prey eggs or nymphs. The findings from this study could help select better biological control agents for effective control of T. urticae and other pests in vegetable productions.

Mini-silos were opened and analyzed for fermentation characteristics and soluble N fractions. A subsample of wet silage from each mini-silo was ground to 4 mm and stored at -20 degrees C. Silages were thawed and subjected to 9 h ruminal in vitro incubations to measure gas production and volatile fatty acid (VFA) production as well as microbial biomass yield (MBY) and microbial non-ammonia N (MNAN) formation using N-15 as a marker. In all four experiments, silage fermentation products and indicated good preservation across all treatments. Analysis of data showed that FA- and LP-treated silages had lower concentrations of ammonia-N and free amino acids N than control. The FA treatment was lower in soluble N, but higher in peptide-N, than control. Silage pH was lowest in FA (4.25), followed by LP (4.28), and control (4.38). Ruminal in vitro gas production and VFA concentrations were not different among treatments (P>0.05). Compared to control, FA- and LP-treated silage yielded greater MNAN and MBY. These findings suggested that L. plantarum preserved more true protein during silage fermentation than control, which in turn increased in vitro ruminal microbial growth. Published by Elsevier B.V.

In the fire ant Solenopsis invicta, the existence of two divergent forms of social organization is under the control of a single Mendelian genomic element marked by two variants of an odorant-binding protein gene(4-8). Here we characterize the genomic region responsible for this important social polymorphism, and show that it is part of a pair of heteromorphic chromosomes that have many of the key properties of sex chromosomes. The two variants, hereafter referred to as the social B and social b (SB and Sb) chromosomes, are characterized by a large region of approximately 13 megabases (55% of the chromosome) in which recombination is completely suppressed between SB and Sb. Recombination seems to occur normally between the SB chromosomes but not between Sb chromosomes because Sb/Sb individuals are non-viable. Genomic comparisons revealed limited differentiation between SB and Sb, and the vast majority of the 616 genes identified in the non-recombining region are present in the two variants. The lack of recombination over more than half of the two heteromorphic social chromosomes can be explained by at least one large inversion of around 9 megabases, and this absence of recombination has led to the accumulation of deleterious mutations, including repetitive elements in the non-recombining region of Sb compared with the homologous region of SB. Importantly, most of the genes with demonstrated expression differences between individuals of the two social forms reside in the non-recombining region. These findings highlight how genomic rearrangements can maintain divergent adaptive social phenotypes involving many genes acting together by locally limiting recombination.

TI Antibiotics as Part of the Management of Severe Acute Malnutrition SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID USE THERAPEUTIC FOOD; BLOOD-STREAM INFECTIONS; HOME-BASED THERAPY; COMMUNITY-ACQUIRED BACTEREMIA; MALNOURISHED CHILDREN; MALAWIAN CHILDREN; CHILDHOOD MALNUTRITION; UNDERNUTRITION; KWASHIORKOR; POPULATION AB BACKGROUND Severe acute malnutrition contributes to 1 million deaths among children annually. Adding routine antibiotic agents to nutritional therapy may increase recovery rates and decrease mortality among children with severe acute malnutrition treated in the community. METHODS In this randomized, double-blind, placebo-controlled trial, we randomly assigned Malawian children, 6 to 59 months of age, with severe acute malnutrition to receive amoxicillin, cef-di-nir, or placebo for 7 days in addition to ready-to-use therapeutic food for the outpatient treatment of uncomplicated severe acute malnutrition. The primary outcomes were the rate of nutritional recovery and the mortality rate. RESULTS A total of 2767 children with severe acute malnutrition were enrolled. In the amoxicillin, cef-di-nir, and placebo groups, 88.7%, 90.9%, and 85.1% of the children recovered, respectively (relative risk of treatment failure with placebo vs. amoxicillin, 1.32; 95% confidence interval [CI], 1.04 to 1.68; relative risk with placebo vs. cef-di-nir, 1.64; 95% CI, 1.27 to 2.11). The mortality rates for the three groups were 4.8%, 4.1%, and 7.4%, respectively (relative risk of death with placebo vs. amoxicillin, 1.55; 95% CI, 1.07 to 2.24; relative risk with placebo vs. cef-di-nir, 1.80; 95% CI, 1.22 to 2.64). Among children who recovered, the rate of weight gain was increased among those who received antibiotics. No interaction between type of severe acute malnutrition and intervention group was observed for either the rate of nutritional recovery or the mortality rate. CONCLUSIONS The addition of antibiotics to therapeutic regimens for uncomplicated severe acute malnutrition was associated with a significant improvement in recovery and mortality rates.

TI Comparison and contrast of genes and biological pathways responding to Marek's disease virus infection using allele-specific expression and differential expression in broiler and layer chickens SO BMC GENOMICS LA English DT Article DE Marek's disease; Genetic resistance; RNA-Seq; Allele-specific expression; Biological pathways ID AFFECTING SUSCEPTIBILITY; MICROCHROMOSOME; RESISTANCE; COMPLEX; CULTURE; AGENT AB Background: Marek's disease (MD) is a commercially important neoplastic disease of chickens caused by the Marek's disease virus (MDV), a naturally occurring oncogenic alphaherpesvirus. Enhancing MD genetic resistance is desirable to augment current vaccines and other MD control measures. High throughput sequencing was used to profile splenic transcriptomes from individual F1 progeny infected with MDV at 4 days of age from both outbred broilers (meat-type) and inbred layer (egg-type) chicken lines that differed in MD genetic resistance. The resulting information was used to identify SNPs, genes, and biological pathways exhibiting allele-specific expression (ASE) in response to MDV infection in each type of chicken. In addition, we compared and contrasted the results of pathway analyses (ASE and differential expression (DE)) between chicken types to help inform on the biological response to MDV infection. Results: With 7 individuals per line and treatment group providing high power, we identified 6,132 single nucleotide polymorphisms (SNPs) in 4,768 genes and 4,528 SNPs in 3,718 genes in broilers and layers, respectively, that exhibited ASE in response to MDV infection. Furthermore, 548 and 434 genes in broilers and layers, respectively, were found to show DE following MDV infection. Comparing the datasets, only 72 SNPs and 850 genes for ASE and 20 genes for DE were common between the two bird types. Although the chicken types used in this study were genetically different, at the pathway level, both TLR receptor and JAK/STAT signaling pathways were enriched as well as exhibiting a high proportion of ASE genes, especially at the beginning of both above mentioned regulatory pathways. Conclusions: RNA sequencing with adequate biological replicates is a powerful approach to identify high confidence SNPs, genes, and pathways that are associated with transcriptional response to MDV infection. In addition, the SNPs exhibiting ASE in response to MDV infection provide a strong foundation for determining the extent to which variation in expression influences MD incidence plus yield genetic markers for genomic selection. However, given the paucity of overlap among ASE SNP sets (broilers vs. layers), it is likely that separate screens need to be incorporated for each population. Finally, comparison of gene lists obtained between these two diverse chicken types indicate the TLR and JAK/STAT signaling are conserved when responding to MDV infection and may be altered by selection of genes exhibiting ASE found at the start of each pathway.

TI Phosphorus losses from agricultural watersheds in the Mississippi Delta SO JOURNAL OF ENVIRONMENTAL MANAGEMENT LA English DT Article DE Rainfall; Runoff; Sediment loss; Ortho-P loss; TP loss; Soil P; Agricultural management practices; Tillage ID EXTRACTABLE SOIL-PHOSPHORUS; RUNOFF PHOSPHORUS; TILLAGE SYSTEMS; EUTROPHICATION; ACCUMULATION; ALBERTA AB Phosphorus (P) loss from agricultural fields is of environmental concern because of its potential impact on water quality in streams and lakes. The Mississippi Delta has long been known for its fish productivity and recreational value, but high levels of P in fresh water can lead to algal blooms that have many detrimental effects on natural ecosystems. Algal blooms interfere with recreational and aesthetic water use. However, few studies have evaluated P losses from agricultural watersheds in the Mississippi Delta. To better understand the processes influencing P loss, rainfall, surface runoff, sediment, ortho-P (orthophosphate, PO4-P), and total P (TP) were measured (water years 1996-2000) for two subwatersheds (UL1 and UL2) of the Deep Hollow Lake Watershed and one subwatershed of the Beasley Lake Watershed (BL3) primarily in cotton production in the Mississippi Delta. Ortho-P concentrations ranged from 0.01 to 1.0 mg/L with a mean of 0.17 mg/L at UL1 (17.0 ha), 0.36 mg/L at UL2 (11.2 ha) and 0.12 mg/L at BL3 (7.2 ha). The TP concentrations ranged from 0.14 to 7.9 mg/L with a mean of 0.96 mg/L at UL1, 1.1 mg/L at UL2 and 1.29 mg/L at BL3. Among the three sites, UL1 and UL2 received P application in October 1998, and BL3 received P applications in the spring of 1998 and 1999. At UL1, ortho-P concentrations were 0.36, 0.25 and 0.16 for the first, second and third rainfall events after P application, respectively; At UL2, ortho-P concentrations were 1.0, 0.66 and 0.65 for the first, second and third rainfall events after P application, respectively; and at BL3, ortho-P concentrations were 0.11, 0.22 and 0.09 for the first, second and third rainfall events after P application, respectively. P fertilizer application did influence P losses, but high P concentrations observed in surface runoff were not always a direct result of P fertilizer application or high rainfall. Application of P in the fall (UL1 and UL2) resulted in more ortho-P losses, likely because high rainfall often occurred in the winter months soon after application. The mean ortho-P concentrations were higher at UL1 and UL2 than those at BL3, although BL3 received more P application during the monitoring period, because P was applied in spring at BL3. However, tillage associated with planting and incorporating applied P in the spring (BL3) may have resulted in more TP loss in sediment, thus the mean TP concentration was the highest at BL3. Ortho-P loss was correlated with surface runoff; and TP loss was correlated with sediment loss. These results indicate that applying P fertilizer in the spring may be recommended to reduce potential ortho-P loss during the fallow winter season; in addition, conservation practices may reduce potential TP loss associated with soil loss.

Methods: Repeated samples from 97 locations were collected systematically across SRS and analyzed for radionuclide activity. Radionuclide activity concentrations found in litter and duff were compared. As spatial trends were of interest, spatial distributions of radionuclide activity concentrations found in litter and duff and spatial dependency amongst the data were explored. Results: Be-7, K-40, and Cs-137 showed statistically significant proportional differences between litter and duff samples. Duff sample concentrations for Cs-137 (p < 0.0001) and K-40 (p = 0.0015) were statistically higher compared to litter samples. Be-7 activity concentrations were statistically higher in litter as compared to duff (p < 0.0001). For K-40 litter and duff samples, spatial correlation tests were not significant at p = 0.05 and the maps did not indicate any apparent high concentrations centered near possible radionuclide sources (i.e. SRS facilities). For Be-7 litter samples, significant spatial correlation was calculated (p = 0.0085). No spatial correlation was evident in the Be-7 duff samples (p = 1.0000) probably due to small sample size (n = 7). Cs-137 litter and duff samples showed significant spatial correlations (p < 0.0001 and p < 0.0001, respectively). Conclusions: To date, few studies characterize radionuclide activity concentrations in litter and duff, and to our knowledge none present spatial analysis. Key findings show that across SRS, Cs-137 is the primary radionuclide of concern, with the highest number of samples reported above MDC in litter (51.4%) and duff samples (83.2%). However, Cs-137 litter and duff spatial trends in the maps generated from the kriging parameters do not appear to directly link the areas with higher activity concentrations with SRS facilities. The results found herein provide valuable baseline monitoring data for future studies of forest surface fuels and can be used to evaluate changes in radioactivity in surface fuels in the southeast region of the U.S. (C) 2012 Elsevier Ltd.

TI Efficacy of various naturally occurring caffeic acid derivatives in preventing post-harvest protein losses in forages SO JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE LA English DT Article DE alfalfa; red clover; polyphenol oxidase; phenolics; proteolysis; silage ID RED-CLOVER SILAGE; POLYPHENOL OXIDASE; CHLOROGENIC ACID; HYDROXYCINNAMOYL TRANSFERASE; PHASELIC ACID; O-DIPHENOLS; DRY-MATTER; PROTEOLYSIS; ALFALFA; BIOSYNTHESIS AB BACKGROUND: In red clover, oxidation of endogenous o-diphenols by polyphenol oxidase (PPO) inhibits post-harvest proteolyis. This system is transferable to alfalfa by providing PPO (via a transgene) and o-diphenol PPO substrates (via exogenous application). To exploit the PPO system for protein protection, it would be advantageous to produce PPO substrates in alfalfa, which lacks them. We assessed the extent of PPO-mediated proteolytic inhibition by phenolic compounds, especially those whose biosynthesis could be engineered into alfalfa. RESULTS: Tested compounds included o-diphenols (caffeic acid, phaselic acid, chlorogenic acid, clovamide) and monophenols (p-coumaric acid, p-coumaroyl-malic acid). In the presence of PPO, 2 mmol o-diphenol g(-1) protein reduced 24 h proteolysis 68-87% (P < 0.001) and as little as 0.25 mmol g(-1) protein still decreased 24 h proteolysis 43-60% (P < 0.001). At high concentrations, clovamide inhibited 24 h proteolysis 50% (P < 0.001) in the absence of PPO, likely due to non-PPO oxidation. Monophenol p-coumaric acid did not inhibit 24 h proteolyis, although high levels of its malate ester did exhibit PPO- and oxygen-independent inhibition (37%, P < 0.001). CONCLUSIONS: For PPO-mediated proteolytic inhibition, pathways for both phaselic acid and chlorogenic acid may be good targets for engineering into alfalfa. Clovamide may be useful for inhibiting proteolysis without PPO. Published 2012 by John Wiley & Sons, Ltd.

This is especially true with high-valued specialty rice, because profit loss will be greater. The objective of this work was to determine whether a significant change occurs in the physicochemical properties (apparent amylose and protein concentrations, viscosity profile and gelatinisation temperature) as a result of induced PHY. RESULTS: In this study, four specialty rices (Basmati, Jasmine, Arborio and Sushi) were yellowed using a laboratory method. PHY increased apparent amylose concentration. It also significantly increased onset and peak gelatinisation temperatures. However, peak, breakdown and setback Rapid ViscoAnalyzer viscosities were decreased by PHY. Trough viscosity for Basmati and Jasmine decreased, whereas it increased for Arborio. Moisture and protein concentrations were unchanged by the yellowing process. Attempts to rehydrate the kernels after induced PHY caused them to fracture, thus making them unsuitable for their intended purpose. CONCLUSION: This study indicates that rice that has been subjected to PHY shows a reduction not only in appearance but also in cooking and processing quality, decreasing its value. However, the changes differed for each rice type, with Jasmine being affected the least. Published 2012 by John Wiley & Sons, Ltd.

Although some of these nitrocompounds, nitroethane and 2-nitropropane, for example, have been industrial chemicals and synthetic intermediates for years, others such as carboxymethyl nitro-amino acid analogues are new to science and have not been previously described. The purpose of this paper is to review the toxicological profiles, especially as related to events occurring during metabolism and biotransformation, which contribute to toxicological end points of established nitroaliphatic compounds. It is hoped that by summarizing existing knowledge, an understanding of the activities and toxicological profiles of newly established nitrocompounds might be anticipated or adverse events associated with their use might be avoided.

Most microbial cold-active lipases originate from psychrotrophic and psychrophilic microorganisms found in Antarctic regions, which has led to difficulties in the practical production of cold-active lipase. Recently, a mesophilic yeast, Pichia lynferdii NRRL Y-7723, was reported to produce a novel cold-active lipase. This study focused on optimization of environmental factors, while giving particular attention to the relationships between given factors and incubation time, to maximize the production of a novel cold-active lipase from P. lynferdii NRRL Y-7723. Maximum lipase production was highly dependent on the incubation time at a given environmental factor. Lipase production varied with incubation time at a given temperature, and 20 degrees C was selected as the optimum temperature for lipase production. Fructose was selected as the best carbon source, and maximum lipase production was obtained when it was present at 0.7% (w/v). Yeast extract was an efficient organic nitrogen source, with maximum lipase production occurring at 0.996 (w/v). Specifically, at the optimum yeast extract level the lipase production was >10 times higher than the productivity under standard conditions. All natural oils tested showed lipase production, but their maximum productivities varied according to incubation time and oil species.

These BoCV from the respiratory tract of healthy and clinically ill cattle with BRD signs were compared to reference and vaccine strains based on Spike protein coding sequences and VNT using convalescent antisera. Based on this study, the BoCV isolates belong to one of two genomic clades (clade 1 and 2) which can be differentiated antigenically. The respiratory isolates from Oklahoma in this study were further divided by genetic differences into three subclades, 2a, 2b, and 2c. Reference enteric BoCV strains and a vaccine strain were in clade 1. Currently available vaccines designed to control enteric disease are based on viruses from one clade while viruses isolated from respiratory tracts, in this study, belong to the other clade.

Previous report revealed the presence of aMPV/C in wild birds in the southeast regions of the U.S. Methods: In this study, aMPV/C positive oral swabs from American coots (AC) and Canada geese (CG) were passaged three times in the respiratory tract of specific pathogen free (SPF) turkeys and used as aMPV/C P3 virus isolates in subsequent studies. Results: Wild bird P3 isolates showed similar growth characteristics when compared to virulent aMPV/C in chicken embryo fibroblast (CEF) cell cultures and their glycoprotein G gene sequence was closely related to the G gene of aMPV/C Colorado reference virus. Three-day-old commercial or SPF turkeys were inoculated oculonasally with wild bird aMPV/C P3 isolates. At 5 and 7 days post-inoculation (DPI), severe clinical signs were observed in both of the AC and CG virus-exposed groups. Viral RNA was detected in tracheal swabs by reverse transcriptase polymerase chain reaction (RT-PCR). In addition, immunohistochemistry showed virus replication in the nasal turbinate and trachea. All virus-exposed turkeys developed positive antibody response by 14 DPI. Conclusions: Our data demonstrate that aMPV/C wild bird isolates induced typical aMPV/C disease in the domestic turkeys.

This process yielded stable aqueous solutions that could be dried and then re-dispersed in water for end-use applications. Reaction products were characterized by inductively coupled plasma-atomic emission spectroscopy (ICP-AES), UV-VIS spectroscopy, X-ray diffraction, TEM. SEM and light microscopy. Addition of acid to reduce the pH of aqueous starch-AgNP solutions produced an increase in viscosity, and nearly quantitative precipitation of starch-AgNP was observed at low pH. Smaller AgNP and higher conversions of silver nitrate to water-soluble starch-AgNP were obtained in this process, as compared with a process carried out under similar conditions using a commercial soluble starch as a stabilizer.

The Pt genome, currently estimated at 135 Mb, is significantly larger than Pgt, at 88 Mb, but the reason for the expansion is unknown. Three genomic loci of Pt conserved proteins were characterized to gain insight into gene content, genome complexity and expansion. Results: A bacterial artificial chromosome (BAC) library was made from P. triticina race 1, BBBD and probed with Pt homologs of genes encoding two predicted Pgt secreted effectors and a DNA marker mapping to a region of avirulence. Three BACs, 103 Kb, 112 Kb, and 166 Kb, were sequenced, assembled, and open reading frames were identified. Orthologous genes were identified in Pgt and local conservation of gene order (microsynteny) was observed. Pairwise protein identities ranged from 26 to 99%. One Pt BAC, containing a RAD18 ortholog, shares syntenic regions with two Pgt scaffolds, which could represent both haplotypes of Pgt. Gene sequence is diverged between the species as well as within the two haplotypes. In all three BAC clones, gene order is locally conserved, however, gene shuffling has occurred relative to Pgt. These regions are further diverged by differing insertion loci of LTR-retrotransposon, Gypsy, Copia, Mutator, and Harbinger mobile elements. Uncharacterized Pt open reading frames were also found; these proteins are high in lysine and similar to multiple proteins in Pgt. Conclusions: The three Pt loci are conserved in gene order, with a range of gene sequence divergence. Conservation of predicted haustoria expressed secreted protein genes between Pt and Pgt is extended to the more distant poplar rust, Melampsora larici-populina. The loci also reveal that genome expansion in Pt is in part due to higher occurrence of repeat-elements in this species.

In United States and European watersheds, where atmospheric deposition of inorganic N is moderate to low (<10 kg.ha.y), disturbance of forests by timber harvest or violent storms causes an increase in stream nitrate concentration that typically is close to 400% of predisturbance concentrations. In contrast, no significant increase in streamwater nitrate concentrations has occurred following extensive tree mortality caused by the mountain pine beetle in Colorado. A model of nitrate release from Colorado watersheds calibrated with field data indicates that stimulation of nitrate uptake by vegetation components unaffected by beetles accounts for significant nitrate retention in beetle-infested watersheds. The combination of low atmospheric N deposition (<10 kg.ha.y), tree mortality spread over multiple years, and high compensatory capacity associated with undisturbed residual vegetation and soils explains the ability of these beetle-infested watersheds to retain nitrate despite catastrophic mortality of the dominant canopy tree species.

However, there is no efficient method for producing defensins. In this study, we developed a new strategy to produce defensin in nitrate reductase (NR)-deficient C. ellipsoidea (nrm-4). We constructed a plant expression vector carrying mutated NP-1 gene (mNP-1), a mature alpha-defensin NP-1 gene from rabbit with an additional initiator codon in the 5'-terminus, in which the selection markers were NptII and NR genes. We transferred mNP-1 into nrm-4 using electroporation and obtained many transgenic lines with high efficiency under selection chemicals G418 and NaNO3. The mNP-1 was characterized using N-terminal sequencing after being isolated from transgenic lines. Excitingly, mNP-1 was produced at high levels (approximately 11.42 mg/l) even after 15 generations of continuous fermentation. In addition, mNP-1 had strong activity against Escherichia coli at 5 mu g/ml. This research developed a new method for producing defensins using genetic engineering.

TI Lignosulfonate and elevated pH can enhance enzymatic saccharification of lignocelluloses SO BIOTECHNOLOGY FOR BIOFUELS LA English DT Article DE Enzymatic hydrolysis/saccharification; Lignin/lignosulfonate; Nonspecific/nonproductive binding/adsorption; Cellulase enzymes; Pretreatment ID PRETREATED LODGEPOLE PINE; CELLULOSIC ETHANOL-PRODUCTION; TRICHODERMA-REESEI; SACCHAROMYCES-CEREVISIAE; LIGNIN CONTENT; DILUTE-ACID; HYDROLYSIS; ADSORPTION; SPORL; SOFTWOOD AB Background: Nonspecific (nonproductive) binding (adsorption) of cellulase by lignin has been identified as a key barrier to reduce cellulase loading for economical sugar and biofuel production from lignocellulosic biomass. Sulfite Pretreatment to Overcome Recalcitrance of Lignocelluloses (SPORL) is a relatively new process, but demonstrated robust performance for sugar and biofuel production from woody biomass especially softwoods in terms of yields and energy efficiencies. This study demonstrated the role of lignin sulfonation in enhancing enzymatic saccharification of lignocelluloses-lignosulfonate from SPORL can improve enzymatic hydrolysis of lignocelluloses, contrary to the conventional belief that lignin inhibits enzymatic hydrolysis due to nonspecific binding of cellulase. Results: The study found that lignosulfonate from SPORL pretreatment and from a commercial source inhibits enzymatic hydrolysis of pure cellulosic substrates at low concentrations due to nonspecific binding of cellulase. Surprisingly, the reduction in enzymatic saccharification efficiency of a lignocellulosic substrate was fully recovered as the concentrations of these two lignosulfonates increased. We hypothesize that lignosulfonate serves as a surfactant to enhance enzymatic hydrolysis at higher concentrations and that this enhancement offsets its inhibitive effect from nonspecific binding of cellulase, when lignosulfonate is applied to lignocellulosic solid substrates. Lignosulfonate can block nonspecific binding of cellulase by bound lignin on the solid substrates, in the same manner as a nonionic surfactant, to significantly enhance enzymatic saccharification. This enhancement is linearly proportional to the amount of lignosulfonate applied which is very important to practical applications. For a SPORL-pretreated lodgepole pine solid, 90% cellulose saccharification was achieved at cellulase loading of 13 FPU/g glucan with the application of its corresponding pretreatment hydrolysate coupled with increasing hydrolysis pH to above 5.5 compared with only 51% for the control run without lignosulfonate at pH 5.0. The pH-induced lignin surface modification at pH 5.5 further reduced nonspecific binding of cellulase by lignosulfonate. Conclusions: The results reported in this study suggest significant advantages for SPORL-pretreatment in terms of reducing water usage and enzyme dosage, and simplifying process integration, i.e., it should eliminate washing of SPORL solid fraction for direct simultaneous enzymatic saccharification and combined fermentation of enzymatic and pretreatment hydrolysates (SSCombF). Elevated pH 5.5 or higher, rather than the commonly believed optimal and widely practiced pH 4.8-5.0, should be used in conducting enzymatic saccharification of lignocelluloses. C1 [Wang, Z.

Alphavirus-derived replicon particles have been shown to be safe and highly effective vaccine vectors against a variety of human and veterinary pathogens. Replicon particles are non-propagating, DIVA compatible, and can induce both humoral and cell mediated immune responses. This is the first experiment to demonstrate that Alphavirus-based replicon particles can be utilized in a standard prime/boost vaccination strategy in calves against a commercially significant bovine pathogen. Findings: Replicon particles that express bovine viral diarrhea virus sub-genotype 1b E2 glycoprotein were generated and expression was confirmed in vitro using polyclonal and monoclonal antibodies specific to E2. Vaccine made from particles was generated in Vero cells and administered to BVDV free calves in a prime/boost regimen at two dosage levels. Vaccination resulted in neutralizing antibody titers that cross-neutralized both type 1 and type 2 BVD genotypes following booster vaccination. Additionally, high dose vaccine administration demonstrated some protection from clinical disease and significantly reduced the degree of leukopenia caused by viral infection. Conclusions: Replicon particle vaccines administered in a prime/boost regimen expressing BVDV E2 glycoprotein can induce cross-neutralizing titers, reduce leukopenia post challenge, and mitigate clinical disease in calves. This strategy holds promise for a safe and effective vaccine to BVDV.

This study presents a framework for using independent estimates of land surface temperature from five microwave satellite sensors to improve the accuracy of land surface temperature output from a numerical weather prediction system in an off-line (postprocessing) analysis. First, structural differences in timing and amplitude of the temperature signal were addressed. Then, satellite observations were assimilated into an auto-regressive error model, formulated to estimate errors in the numerical weather prediction output. Errors in daily minimum and amplitude were treated separately. Results of this study provide new insights about potential added benefits of preprocessing and off-line assimilation of microwave remote sensing-based and model-based temperature retrievals. It is shown that the satellite observations may be used to reduce errors in surface temperature, particularly for day-time hours. Preprocessing is responsible for the bulk of this reduction in temperature error; data assimilation is shown to further reduce the random temperature error by a few tenths of a Kelvin, accounting for a 10% reduction in RMSE.

AB The objective of this research was to identify single nucleotide polymorphisms (SNPs) and to develop an Illumina Infinium BeadChip that contained over 50,000 SNPs from soybean (Glycine max L. Merr.). A total of 498,921,777 reads 35-45 bp in length were obtained from DNA sequence analysis of reduced representation libraries from several soybean accessions which included six cultivated and two wild soybean (G. soja Sieb. et Zucc.) genotypes. These reads were mapped to the soybean whole genome sequence and 209,903 SNPs were identified. After applying several filters, a total of 146,161 of the 209,903 SNPs were determined to be ideal candidates for Illumina Infinium II BeadChip design. To equalize the distance between selected SNPs, increase assay success rate, and minimize the number of SNPs with low minor allele frequency, an iteration algorithm based on a selection index was developed and used to select 60,800 SNPs for Infinium BeadChip design. Of the 60,800 SNPs, 50,701 were targeted to euchromatic regions and 10,000 to heterochromatic regions of the 20 soybean chromosomes. In addition, 99 SNPs were targeted to unanchored sequence scaffolds. Of the 60,800 SNPs, a total of 52,041 passed Illumina's manufacturing phase to produce the SoySNP50K iSelect BeadChip. Validation of the SoySNP50K chip with 96 landrace genotypes, 96 elite cultivars and 96 wild soybean accessions showed that 47,337 SNPs were polymorphic and generated successful SNP allele calls. In addition, 40,841 of the 47,337 SNPs (86%) had minor allele frequencies >= 10% among the landraces, elite cultivars and the wild soybean accessions. A total of 620 and 42 candidate regions which may be associated with domestication and recent selection were identified, respectively. The SoySNP50K iSelect SNP beadchip will be a powerful tool for characterizing soybean genetic diversity and linkage disequilibrium, and for constructing high resolution linkage maps to improve the soybean whole genome sequence assembly.

TI Characterization of the basal angiosperm Aristolochia fimbriata: a potential experimental system for genetic studies SO BMC PLANT BIOLOGY LA English DT Article ID SARUMA-HENRYI OLIV; FLOWER DEVELOPMENT; ESCHSCHOLZIA-CALIFORNICA; WILLD. ARISTOLOCHIACEAE; FLORAL DIVERSIFICATION; PHYLOGENETIC ANALYSIS; COMPARATIVE GENOMICS; POLLINATION BIOLOGY; BATTUS-PHILENOR; PLANT BIOLOGY AB Background: Previous studies in basal angiosperms have provided insight into the diversity within the angiosperm lineage and helped to polarize analyses of flowering plant evolution. However, there is still not an experimental system for genetic studies among basal angiosperms to facilitate comparative studies and functional investigation. It would be desirable to identify a basal angiosperm experimental system that possesses many of the features found in existing plant model systems (e. g., Arabidopsis and Oryza). Results: We have considered all basal angiosperm families for general characteristics important for experimental systems, including availability to the scientific community, growth habit, and membership in a large basal angiosperm group that displays a wide spectrum of phenotypic diversity. Most basal angiosperms are woody or aquatic, thus are not well-suited for large scale cultivation, and were excluded. We further investigated members of Aristolochiaceae for ease of culture, life cycle, genome size, and chromosome number. We demonstrated self-compatibility for Aristolochia elegans and A. fimbriata, and transformation with a GFP reporter construct for Saruma henryi and A. fimbriata. Furthermore, A. fimbriata was easily cultivated with a life cycle of just three months, could be regenerated in a tissue culture system, and had one of the smallest genomes among basal angiosperms. An extensive multi-tissue EST dataset was produced for A. fimbriata that includes over 3.8 million 454 sequence reads. Conclusions: Aristolochia fimbriata has numerous features that facilitate genetic studies and is suggested as a potential model system for use with a wide variety of technologies. Emerging genetic and genomic tools for A. fimbriata and closely related species can aid the investigation of floral biology, developmental genetics, biochemical pathways important in plant-insect interactions as well as human health, and various other features present in early angiosperms.

TI Characterization of Genetic Diversity and Linkage Disequilibrium of ZmLOX4 and ZmLOX5 Loci in Maize SO PLOS ONE LA English DT Article ID DNA POLYMORPHISM; JASMONIC ACID; ZEA-MAYS; POPULATIONS; GENOME; LIPOXYGENASE; DISRUPTION; RESISTANCE; AFLATOXIN; PATTERNS AB Maize (Zea mays L.) lipoxygenases (ZmLOXs) are well recognized as important players in plant defense against pathogens, especially in cross kingdom lipid communication with pathogenic fungi. This study is among the first to investigate genetic diversity at important gene paralogs ZmLOX4 and ZmLOX5. Sequencing of these genes in 400 diverse maize lines showed little genetic diversity and low linkage disequilibrium in the two genes. Importantly, we identified one inbred line in which ZmLOX5 has a disrupted open reading frame, a line missing ZmLOX5, and five lines with a duplication of ZmLOX5. Tajima's D test suggests that both ZmLOX4 and ZmLOX5 have been under neutral selection. Further investigation of haplotype data revealed that within the ZmLOX family members only ZmLOX12, a monocot specific ZmLOX, showed strong linkage disequilibrium that extends further than expected in maize. Linkage disequilibrium patterns at these loci of interest are crucial for future candidate gene association mapping studies. ZmLOX4 and ZmLOX5 mutations and copy number variants are under further investigation for crop improvement.

TI Host Identity Matters in the Amphibian-Batrachochytrium dendrobatidis System: Fine-Scale Patterns of Variation in Responses to a Multi-Host Pathogen SO PLOS ONE LA English DT Article ID EMERGING INFECTIOUS-DISEASES; POPULATION DECLINES; INTERSPECIFIC VARIATION; PEPTIDE DEFENSES; CHYTRIDIOMYCOSIS; DYNAMICS; SUSCEPTIBILITY; ECOLOGY; FUNGUS; FROGS AB Species composition within ecological assemblages can drive disease dynamics including pathogen invasion, spread, and persistence. In multi-host pathogen systems, interspecific variation in responses to infection creates important context dependency when predicting the outcome of disease. Here, we examine the responses of three sympatric host species to a single fungal pathogen, Batrachochytrium dendrobatidis, which is associated with worldwide amphibian population declines and extinctions. Using an experimental approach, we show that amphibian species from three different genera display significant differences in patterns of pathgen-induced mortality as well as the magnitude and temporal dynamics of infection load. We exposed amphibians to one of four inoculation dose treatments at both larval and post- metamorphic stages and quantified infection load on day 8 and day 15 post-inoculation. Of the three species examined, only one (the Pacific treefrog; Pseudacris regilla) displayed "dose-dependent" responses; survival was reduced and infection load was elevated as inoculation dose was increased. We observed a reduction in survival but no differences in infection load across pathogen treatments in Cascades frogs (Rana cascadae). Western toads (Anaxyrus boreas) displayed differences in infection load but no differences in survival across pathogen treatments. Within species, responses to the pathogen varied with life history stage, and the most heavily infected species at the larval stage was different from the most heavily infected species at the post-metamorphic stage. Temporal changes in infection load were species and life history stage-specific. We show that variation in susceptibility to this multi-host pathogen is complex when viewed at a fine-scale and may be mediated through intrinsic host traits.

TI Sequencing and De Novo Assembly of the Western Tarnished Plant Bug (Lygus hesperus) Transcriptome SO PLOS ONE LA English DT Article ID HEAT-SHOCK PROTEINS; DROSOPHILA-MELANOGASTER; HETEROPTERA MIRIDAE; HEMIPTERA-MIRIDAE; BROWN PLANTHOPPER; STRESS-RESPONSE; POPULATIONS; EVOLUTIONARY; MISSISSIPPI; RESISTANCE AB Background: Mirid plant bugs (Hemiptera: Miridae) are economically important insect pests of many crops worldwide. The western tarnished plant bug Lygus hesperus Knight is a pest of cotton, alfalfa, fruit and vegetable crops, and potentially of several emerging biofuel and natural product feedstocks in the western US. However, little is known about the underlying molecular genetics, biochemistry, or physiology of L. hesperus, including their ability to survive extreme environmental conditions. Methodology/Principal Findings: We used 454 pyrosequencing of a normalized adult cDNA library and de novo assembly to obtain an adult L. hesperus transcriptome consisting of 1,429,818 transcriptomic reads representing 36,131 transcript isoforms (isotigs) that correspond to 19,742 genes. A search of the transcriptome against deposited L. hesperus protein sequences revealed that 86 out of 87 were represented. Comparison with the non-redundant database indicated that 54% of the transcriptome exhibited similarity (e-value <= 1(-5)) with known proteins. In addition, Gene Ontology (GO) terms, Kyoto Encyclopedia of Genes and Genomes (KEGG) annotations, and potential Pfam domains were assigned to each transcript isoform. To gain insight into the molecular basis of the L. hesperus thermal stress response we used transcriptomic sequences to identify 52 potential heat shock protein (Hsp) homologs. A subset of these transcripts was sequence verified and their expression response to thermal stress monitored by semi-quantitative PCR. Potential homologs of Hsp70, Hsp40, and 2 small Hsps were found to be upregulated in the heat-challenged adults, suggesting a role in thermotolerance. Conclusions/Significance: The L. hesperus transcriptome advances the underlying molecular understanding of this arthropod pest by significantly increasing the number of known genes, and provides the basis for further exploration and understanding of the fundamental mechanisms of abiotic stress responses.

In this work, antimicrobial activity in milk of HydH5 [a virion-associated peptidoglycan hydrolase (VAPGH) encoded by the Staphylococcus aureus bacteriophage vB_SauS-phiIPLA88], and three different fusion proteins created between HydH5 and lysostaphin has been assessed. The lytic activity of the five proteins (HydH5, HydH5Lyso, HydH5SH3b, CHAPSH3b and lysostaphin) was confirmed using commercial whole extended shelf-life milk (ESL) in challenge assays with 10(4) CFU/mL of the strain S. aureus Sa9. HydH5, HydH5Lyso and HydH5SH3b (3.5 mu M) kept the staphylococcal viable counts below the control cultures for 6 h at 37 degrees C. The effect is apparent just 15 minutes after the addition of the lytic enzyme. Of note, lysostaphin and CHAPSH3b showed the highest staphylolytic protection as they were able to eradicate the initial staphylococcal challenge immediately or 15 min after addition, respectively, at lower concentration (1 mu M) at 37 degrees C. CHAPSH3b showed the same antistaphyloccal effect at room temperature (1.65 mu M). No re-growth was observed for the remainder of the experiment (up to 6 h). CHAPSH3b activity (1.65 mu M) was also assayed in raw (whole and skim) and pasteurized (whole and skim) milk. Pasteurization of milk clearly enhanced CHAPSH3b staphylolytic activity in both whole and skim milk at both temperatures. This effect was most dramatic at room temperature as this protein was able to reduce S. aureus viable counts to undetectable levels immediately after addition with no re-growth detected for the duration of the experiment (360 min). Furthermore, CHAPSH3b protein is known to be heat tolerant and retained some lytic activity after pasteurization treatment and after storage at 4 degrees C for 3 days. These results might facilitate the use of the peptidoglycan hydrolase HydH5 and its derivative fusions, particularly CHAPSH3b, as biocontrol agents for controlling undesirable bacteria in dairy products.

TI Relative effectiveness of carp pituitary extract, luteininzing hormone releasing hormone analog (LHRHa) injections and LHRHa implants for producing hybrid catfish fry SO AQUACULTURE LA English DT Article DE LHRHa; Implant; CPE; Hybrid catfish ID X BLUE CATFISH; CHANNEL CATFISH; ICTALURUS-PUNCTATUS; INDUCED OVULATION; MANIPULATIONS; REPRODUCTION; FISH AB Adoption of the hybrid catfish (channel catfish, Ictalurus punctatus, female x blue catfish I. furcatus, male) is increasing in the catfish industry. The most effective way to produce fry is hormone induced spawning of females coupled with hand stripping and in vitro fertilization. The success of common carp pituitary extract (CPE), luteinizing hormone releasing hormone analog (LHRHa) injections and LHRHa implants for producing hybrid catfish fry was investigated over the past 15 years. Data from 65 studies, 25, 20 and 20 for CPE, LHRHa injections, and LHRHa implants, respectively, were evaluated. Mean fry/kg female body weight (all females) produced was 948, 2483 and 2765 for CPE, LHRHa injections, and LHRHa implants, respectively. LHRHa administered as an injection or implant produced more (P<0.001) fry/kg than CPE. LHRHa implants and CPE (CV=37.5) gave a more consistent result (CV=35.9) than LHRHA injections (CV=49.9). LHRHa is advantageous for ovulating channel catfish for producing hybrid catfish fry compared to CPE. This advantage is even more important if brood fish, space or time are limiting.

The Top Scoring Pair (TSP), k-Top Scoring Pairs (k-TSP), Support Vector Machines (SVM), and prediction analysis of microarrays (PAM) are four popular classifiers that have comparable performance on multiple cancer datasets. SVM and PAM tend to use a large number of genes and TSP, k-TSP always use even number of genes. In addition, the selection of distinct gene pairs in k-TSP simply combined the pairs of top ranking genes without considering the fact that the gene set with best discrimination power may not be the combined pairs. The k-TSP algorithm also needs the user to specify an upper bound for the number of gene pairs. Here we introduce a computational algorithm to address the problems. The algorithm is named Chisquare-statistic-based Top Scoring Genes (Chi-TSG) classifier simplified as TSG. Results: The TSG classifier starts with the top two genes and sequentially adds additional gene into the candidate gene set to perform informative gene selection. The algorithm automatically reports the total number of informative genes selected with cross validation. We provide the algorithm for both binary and multi-class cancer classification. The algorithm was applied to 9 binary and 10 multi-class gene expression datasets involving human cancers. The TSG classifier outperforms TSP family classifiers by a big margin in most of the 19 datasets. In addition to improved accuracy, our classifier shares all the advantages of the TSP family classifiers including easy interpretation, invariant to monotone transformation, often selects a small number of informative genes allowing follow-up studies, resistant to sampling variations due to within sample operations. Conclusions: Redefining the scores for gene set and the classification rules in TSP family classifiers by incorporating the sample size information can lead to better selection of informative genes and classification accuracy. The resulting TSG classifier offers a useful tool for cancer classification based on numerical molecular data. C1 [Wang, Haiyan] Kansas State Univ, Dept Stat, Manhattan, KS 66506 USA.

Individual grapefruit furanocoumarins exhibited contrasting affinities to foods, where the lipophilic bergamottin and several structurally related dimers bound to foods more tightly than the more polar 6',7'-dihydroxybergamottin. From the investigation of different classes of macromolecules in foods, water-soluble proteins were found to be the major constituents responsible for furanocoumarin sequestration. Studies using bovine serum albumin as a model protein demonstrated the dissociation of grapefruit furanocoumarins from the insoluble juice cloud particles and the subsequent formation of water-soluble bovine serum albumin furanocoumarin complexes. Fluorescence binding assays further demonstrated the binding of bergamottin and 6',7'-dihydroxybergamottin to bovine serum albumin. These results demonstrate that proteins can be sequestration agents of these important dietary furanocoumarins.

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

CESTODA HYMENOLEPIDIDAE; SP. N.; BIOGEOGRAPHY; REDESCRIPTION; DISPERSAL; HISTORY; CLIMATE; PIKAS AB Previously unrecognized species of hymenolepidid cestodes attributable to Arostrilepis Mas-Coma & Tenora, 1997 in arvicoline rodents from the greater Beringian region and western North America are described. Discovery and characterization of these tapeworms contributes to the recognition of a complex of cryptic species distributed across the Holarctic region. Three species are proposed: Arostrilepis gulyaevi sp. n. is named for cestodes in Myodes rufocanus from the Republic of Buryatia, southeastern Siberia and from the Khabarovskiy Kray, Chukotka Autonomous Okrug, and Magadanskaya Oblast', Russian Far East (western Beringia); A. cooki sp. n. is named for cestodes in Myodes gapperi from British Columbia, Canada and Montana, USA; and A. rauschorum sp. n. is named for cestodes in Microtus oeconomus, M. longicaudus, M. pennsylvanicus and M. xanthognathus from the Brooks Range, Seward Peninsula, north-central interior, and Arctic coastal plains of Alaska (eastern Beringia) and Montana, USA. Consistent with recent studies defining diversity in the genus, the form, size, and spination (pattern, shape and size) of the cirrus are diagnostic; species are further distinguished by the relative position and length of the cirrus sac, and arrangement of the testes. Assessment of genetic data from the cytochrome b gene of mitochondrial DNA complements differentiation of this complex based on morphological attributes and confirms known species diversity within the genus. New data for geographical distribution and host specificity of known Arostrilepis spp. indicate that 3 of 12 recognized species have Holarctic distributions extending across Beringia. These include Arostrilepis beringiensis (Kontrimavichus & Smirnova, 1991) in lemmings (species of Lemmus and Synaptomys), A. cf. janickii Makarikov & Kontrimavichus, 2011 in root voles (M. oeconomus) and A. macrocirrosa Makarikov, Gulyaev & Kontrimavichus, 2011 in red backed voles (species of Myodes) and less often other rodent host species.

Several types of molecular markers were developed that are effectively used in lettuce breeding and genetic studies. However only a very limited number of microsattelite-based markers are publicly available. We have employed the method of enriched microsatellite libraries to develop 97 genomic SSR markers. Results: Testing of newly developed markers on a set of 36 Lactuca accession (33 L. sativa, and one of each L. serriola L., L. saligna L., and L. virosa L.) revealed that both the genetic heterozygosity (UHe = 0.56) and the number of loci per SSR (Na = 5.50) are significantly higher for genomic SSR markers than for previously developed EST-based SSR markers (UHe = 0.32, Na = 3.56). Fifty-four genomic SSR markers were placed on the molecular linkage map of lettuce. Distribution of markers in the genome appeared to be random, with the exception of possible cluster on linkage group 6. Any combination of 32 genomic SSRs was able to distinguish genotypes of all 36 accessions. Fourteen of newly developed SSR markers originate from fragments with high sequence similarity to resistance gene candidates (RGCs) and RGC pseudogenes. Analysis of molecular variance (AMOVA) of L. sativa accessions showed that approximately 3% of genetic diversity was within accessions, 79% among accessions, and 18% among horticultural types. Conclusions: The newly developed genomic SSR markers were added to the pool of previously developed EST-SSRs markers. These two types of SSR-based markers provide useful tools for lettuce cultivar fingerprinting, development of integrated molecular linkage maps, and mapping of genes.

TI Altered Protozoan and Bacterial Communities and Survival of Escherichia coli O157:H7 in Monensin-Treated Wastewater from a Dairy Lagoon SO PLOS ONE LA English DT Article ID RIBOSOMAL-RNA SEQUENCES; GRAM-NEGATIVE BACTERIA; MYCOBACTERIUM-AVIUM; ANTIBIOTIC-RESISTANCE; ENHANCES VIRULENCE; O157-H7 SURVIVAL; IN-VITRO; RUMEN; GROWTH; POPULATIONS AB Surviving predation is a fitness trait of Escherichia coli O157:H7 (EcO157) that provides ample time for the pathogen to be transported from reservoirs (e.g. dairies and feedlots) to farm produce grown in proximity. Ionophore dietary supplements that inhibit rumen protozoa may provide such a selective advantage for EcO157 to proliferate in lagoons as the pathogen is released along with the undigested supplement as manure washings. This study evaluated the fate of an outbreak strain of EcO157, protozoan and bacterial communities in wastewater treated with monensin. Although total protozoa and native bacteria were unaffected by monensin, the time for 90% decrease in EcO157 increased from 0.8 to 5.1 days. 18S and 16S rRNA gene sequencing of wastewater samples revealed that monensin eliminated almost all colpodean and oligohymenophorean ciliates, probably facilitating the extended survival of EcO157. Total protozoan numbers remained high in treated wastewater as monensin enriched 94% of protozoan sequences undetected with untreated wastewater. Monensin stimulated 30-fold increases in Cyrtohymena citrina, a spirotrichean ciliate, and also biflagellate bicosoecids and cercozoans. Sequences of gram-negative Proteobacteria increased from 1% to 46% with monensin, but gram-positive Firmicutes decreased from 93% to 46%. It is noteworthy that EcO157 numbers increased significantly (P<0.01) in Sonneborn medium containing monensin, probably due to monensin-inhibited growth of Vorticella microstoma (P<0.05), a ciliate isolated from wastewater. We conclude that dietary monensin inhibits ciliate protozoa that feed on EcO157. Feed supplements or other methods that enrich these protozoa in cattle manure could be a novel strategy to control the environmental dissemination of EcO157 from dairies to produce production environments.

TI Identification of a Nonsense Mutation in CWC15 Associated with Decreased Reproductive Efficiency in Jersey Cattle SO PLOS ONE LA English DT Article ID CALVES; GENE; NUCLEOTIDE; EXPRESSION; HAPLOTYPES; FERTILITY; DISCOVERY; ALIGNMENT; COMPLEX; MARKERS AB With the recent advent of genomic tools for cattle, several recessive conditions affecting fertility have been identified and selected against, such as deficiency of uridine monophosphate synthase, complex vertebral malformation, and brachyspina. The current report refines the location of a recessive haplotype affecting fertility in Jersey cattle using crossover haplotypes, discovers the causative mutation using whole genome sequencing, and examines the gene's role in embryo loss. In an attempt to identify unknown recessive lethal alleles in the current dairy population, a search using deep Mendelian sampling of 5,288 Jersey cattle was conducted for high-frequency haplotypes that have a deficit of homozygotes at the population level. This search led to the discovery of a putative recessive lethal in Jersey cattle on Bos taurus autosome 15. The haplotype, denoted JH1, was associated with reduced fertility, and further investigation identified one highly-influential Jersey bull as the putative source ancestor. By combining SNP analysis of whole-genome sequences aligned to the JH1 interval and subsequent SNP validation a nonsense mutation in CWC15 was identified as the likely causative mutation underlying the fertility phenotype. No homozygous recessive individuals were found in 749 genotyped animals, whereas all known carriers and carrier haplotypes possessed one copy of the mutant allele. This newly identified lethal has been responsible for a substantial number of spontaneous abortions in Jersey dairy cattle throughout the past half-century. With the mutation identified, selection against the deleterious allele in breeding schemes will aid in reducing the incidence of this defect in the population. These results also show that carrier status can be imputed with high accuracy. Whole-genome resequencing proved to be a powerful strategy to rapidly identify a previously mapped deleterious mutation in a known carrier of a recessive lethal allele.

Although tens of thousands of those profiles are publicly available, a lack of an accurate method for mining such data has been a major bottleneck for more widespread use of these useful resources. Results: For general usage of those public resources, we designed FitRankDB as a general repository of fitness profiles, and developed a new search algorithm, FitSearch, for identifying the profiles that have a high similarity score with statistical significance for a given fitness profile. We demonstrated that our new repository and algorithm are highly beneficial to researchers who attempting to make hypotheses based on unknown modes-of-action of bioactive compounds, regardless of the types of experiments that have been performed using yeast deletion-mutant collection in various types of different measurement platforms, especially non-chip-based platforms. Conclusions: We showed that our new database and algorithm are useful when attempting to construct a hypothesis regarding the unknown function of a bioactive compound through small-scale experiments with a yeast deletion collection in a platform independent manner. The FitRankDB and FitSearch enhance the ease of searching public yeast fitness profiles and obtaining insights into unknown mechanisms of action of drugs.

Novel findings include identification of bacterial species present, the degree of thymic atrophy seen, and the inclusion of contact animals that highlighted the ability of HP-PRRSV to rapidly transmit between animals. Furthermore, comprehensive detailed cytokine analysis of serum, bronchoalveolar lavage fluid, and tracheobronchial lymph node tissue homogenate revealed a striking elevation in levels of cytokines associated with both innate and adaptive immunity in HP-PRRSV infected swine, and showed that contact swine differed in the degree of cytokine response.

TI Parental feeding practices in Mexican American families: initial test of an expanded measure SO INTERNATIONAL JOURNAL OF BEHAVIORAL NUTRITION AND PHYSICAL ACTIVITY LA English DT Article DE Feeding practices; Mexican Americans; Latinos; Child weight; Child obesity; Mothers; Fathers; Parent-child relationships; Scale development ID BODY-MASS INDEX; CONFIRMATORY FACTOR-ANALYSIS; PRESCHOOL-AGED CHILDREN; INCOME AFRICAN-AMERICAN; MEASUREMENT INVARIANCE; WEIGHT STATUS; EATING BEHAVIORS; FIT INDEXES; MOTHERS; QUESTIONNAIRE AB Background: Although obesity rates are high among Latino children, relatively few studies of parental feeding practices have examined Latino families as a separate group. Culturally-based approaches to measurement development can begin to identify parental feeding practices in specific cultural groups. This study used qualitative and quantitative methods to develop and test the Parental Feeding Practices (PFP) Questionnaire for use with Mexican American parents. Items reflected both parent's use of control over child eating and child-centered feeding practices. Methods: In the qualitative phase of the research, 35 Latino parents participated in focus groups. Items for the PFP were developed from focus group discussions, as well as adapted from existing parent feeding practice measures. Cognitive interviews were conducted with 37 adults to evaluate items. In the quantitative phase, mothers and fathers of 174 Mexican American children ages 8-10 completed the PFP and provided demographic information. Anthropometric measures were obtained on family members. Results: Confirmatory factor analyses identified four parental feeding practice dimensions: positive involvement in child eating, pressure to eat, use of food to control behavior, and restriction of amount of food. Factorial invariance modeling suggested equivalent factor meaning and item response scaling across mothers and fathers. Mothers and fathers differed somewhat in their use of feeding practices. All four feeding practices were related to child body mass index (BMI) percentiles, for one or both parents. Mothers reporting more positive involvement had children with lower BMI percentiles. Parents using more pressure to eat had children with lower BMI percentiles, while parents using more restriction had children with higher BMI percentiles. Fathers using food to control behavior had children with lower BMI percentiles. Conclusions: Results indicate good initial validity and reliability for the PFP. It can be used to increase understanding of parental feeding practices, children's eating, and obesity among Mexican Americans, a population at high risk of obesity.

G. Don.] reduces gastrointestinal nematode (GIN) infection in goats fed in confinement, but effects of this forage when fed as a supplement to goats on pasture are unclear. A study was completed in which supplemental feeds (75 and 95% SL leaf meal pellets and a commercial pellet, all fed at 0.91 kg/head/day) were offered to thirty growing male Spanish goats (9 months old, 20.6 +/- 2.8 kg, 10/treatment) grazing perennial warm-season grass pastures in Fort Valley, GA, from September to November, 2010. Fecal and blood samples were taken from individual animals weekly to determine fecal egg count (FEC) and packed cell volume (PCV), respectively, and animal weights were recorded at the start and end of the trial. After 11 weeks grazing, animals were slaughtered for recovery, counting, and speciation of adult GIN from the abomasum and small intestines. There was no difference in FEC between goats fed the 75 and 95% SL leaf meal pellets, but both groups had lower (P < 0.05) FEC than the goats fed the commercial pellets from days 35 to 77. The PCV values were not affected by the dietary treatments. Animal gain per day averaged 102.0, 77.2, and 53.3g for goats fed 95% SL, commercial, and 75% SL pellets, respectively (P < 0.05). The 95% SL leaf meal pellet goats had 93.0 and 47.3% fewer (P < 0.05) total (male + female) adult Haemonchus contortus and Teladorsagia circumcincta, respectively, than control animals, while only male H. contortus were lower (47.6%; P < 0.05) in 75% SL-fed goats compared with commercial pellet-fed animals. Feeding supplemental SL leaf meal pellets improved animal performance (95% SL pellets) and reduced worm burdens (75 and 95% SL pellets) in young grazing goats and is a useful tool for natural GIN control in small ruminants.

All were resistant to fipronil. Four of five were co-resistant to permethrin and coumaphos in addition to being resistant to fipronil. One strain, El Zamora was found multi-resistant to permethrin, coumaphos, fipronil, and amitraz. Selection with fipronil for 3 generations produced a resistance ratio of 8.3 and 9.4 at the LC50 and the LC99 estimates, respectively. Permethrin resistance in El Zamora was possibly linked to elevated esterase (CZEST9) and could be a contributing factor of resistance to fipronil. The implications of resistance for the control of the southern cattle tick in the future are discussed. Published by Elsevier B.V.

TI Saturated linkage map construction in Rubus idaeus using genotyping by sequencing and genome-independent imputation SO BMC GENOMICS LA English DT Article DE Genotyping by sequencing; GBS; RADseq; Imputation; Raspberry; Rubus idaeus; Psuedotestcross; Linkage map; Segregation distortion ID X DOMESTICA BORKH.; REPEAT SSR MARKERS; MICROSATELLITE MARKERS; SNP MARKERS; RAD MARKERS; RASPBERRY; IDENTIFICATION; APPLE; RESISTANCE; POLYMORPHISM AB Background: Rapid development of highly saturated genetic maps aids molecular breeding, which can accelerate gain per breeding cycle in woody perennial plants such as Rubus idaeus (red raspberry). Recently, robust genotyping methods based on high-throughput sequencing were developed, which provide high marker density, but result in some genotype errors and a large number of missing genotype values. Imputation can reduce the number of missing values and can correct genotyping errors, but current methods of imputation require a reference genome and thus are not an option for most species. Results: Genotyping by Sequencing (GBS) was used to produce highly saturated maps for a R. idaeus pseudo-testcross progeny. While low coverage and high variance in sequencing resulted in a large number of missing values for some individuals, a novel method of imputation based on maximum likelihood marker ordering from initial marker segregation overcame the challenge of missing values, and made map construction computationally tractable. The two resulting parental maps contained 4521 and 2391 molecular markers spanning 462.7 and 376.6 cM respectively over seven linkage groups. Detection of precise genomic regions with segregation distortion was possible because of map saturation. Microsatellites (SSRs) linked these results to published maps for cross-validation and map comparison. Conclusions: GBS together with genome-independent imputation provides a rapid method for genetic map construction in any pseudo-testcross progeny. Our method of imputation estimates the correct genotype call of missing values and corrects genotyping errors that lead to inflated map size and reduced precision in marker placement. Comparison of SSRs to published R. idaeus maps showed that the linkage maps constructed with GBS and our method of imputation were robust, and marker positioning reliable. The high marker density allowed identification of genomic regions with segregation distortion in R. idaeus, which may help to identify deleterious alleles that are the basis of inbreeding depression in the species.

Additionally, AR1 and MS1 have evolved cross-resistance to bispyribac-sodium. Studies were conducted to determine if resistance to acetolactate synthase (ALS)-inhibiting herbicides in these biotypes is target-site or non-target-site based. Sequencing and analysis of a 1701 base pair ALS coding sequence revealed Ala(122) to Val and Ala(122) to Thr substitutions in AR1 and AR2, respectively. The imazamox concentrations required for 5096 inhibition of ALS enzyme activity in vitro of AR1 and AR2 were 2.0 and 5.8 times, respectively, greater than the susceptible biotype. Absorption of C-14-bispyribac-sodium, -imazamox, and -penoxsulam was similar in all biotypes. C-14-Penoxsulam translocation out of the treated leaf (<= 2%) was similar among all biotypes. C-14-Bispyribac-treated AR1 and MS1 translocated 31- 43% less radioactivity to aboveground tissue below the treated leaf compared to the susceptible biotype. C-14-Imazamox-treated AR1 plants translocated 39% less radioactivity above the treated leaf and aboveground tissue below the treated leaf, and MS! translocated 54 and 18% less radioactivity to aboveground tissue above and below the treated leaf, respectively, compared to the susceptible biotype. Phosphorimaging results further corroborated the above results. This study shows that altered target site is a mechanism of resistance to imazamox in AR2 and probably in AR1. Additionally, reduced translocation, which may be a result of metabolism, could contribute to imazamox and bispyribac-sodium resistance in AR1 and MS1.

Ethanol yields positively correlated (p < 0.01) with starch contents of kernels of the normal and waxy corn. The average starch-ethanol conversion efficiency of waxy corn (93.0%) was substantially greater than that of normal corn (88.2%). Waxy corn starch consisted of very little amylose and mostly amylopectin that had a shorter average branch chain length than normal corn amylopectin. Regression analyses showed that average amylopectin branch chain lengths and percentage of long branch chains (DP > 37) of waxy corn starch negatively correlated with the starch hydrolysis rate and the ethanol yield. These results indicated that starch structures and properties of the normal and waxy corn had significant effects on the ethanol yield using a cold fermentation process.

Application of the enhanced SWAT model in the Manas River Basin (MRB) in the Tianshan Mountains in northwest China, shows that the approach is viable as evidenced by a Nash-Sutcliff efficiency of 0.65 and a percent bias of -3.7% for daily streamflow and water balance, respectively. The results indicate that the glacier area decreased by 11% during the simulation period from 1961 to 1999, which is within the range of records from other glaciers. On average, glacier melt contributed 25% to streamflow, although glacier area accounts for only 14% of the catchment drainage area in the MRB. Glacier melt was positively correlated to temperature change (R-2 = 0.70, statistical significance P < 0.001) and negatively correlated to precipitation (R-2 = 0.20, statistical significance P < 0.005). The results indicate that glacier melt was more sensitive to temperature change than to precipitation change, implying that modeling the effects of climate change with increasing temperatures and decreasing precipitation should be further studied.

TI Native prairie filter strips reduce runoff from hillslopes under annual row-crop systems in Iowa, USA SO JOURNAL OF HYDROLOGY LA English DT Article DE Agricultural watersheds; Conservation practices; Corn belt; Hydrologic services restoration; Vegetative buffers; Width-position strips ID ADJACENT AGRICULTURAL WATERSHEDS; AGROFORESTRY BUFFER STRIPS; SOIL HYDRAULIC-PROPERTIES; CONCENTRATED FLOW; VEGETATED BUFFERS; RIPARIAN BUFFERS; GRASS BARRIERS; MIDWESTERN US; NUTRIENT LOSS; LAND-COVER AB Intensively managed annual cropping systems have produced high crop yields but have often produced significant ecosystem services alteration, in particular hydrologic regulation loss. Reconversion of annual agricultural systems to perennial vegetation can lead to hydrologic function restoration, but its effect is still not well understood. Therefore, our objective was to assess the effects of strategic introduction of different amounts and location of native prairie vegetation (NPV) within agricultural landscapes on hydrological regulation. The study was conducted in Iowa (USA), and consisted of a fully balanced, replicated, incomplete block design whereby 12 zero-order ephemeral flow watersheds received four treatments consisting of varying proportions (0%, 10%, and 20%) of prairie vegetation located in different watershed positions (footslope vs. contour strips). Runoff volume and rate were measured from 2008 to 2010 (April-October) with an H-Flume installed in each catchment, and automated ISCO samplers. Over the entire study period, we observed a total of 129 runoff events with an average runoff volume reduction of 37% based on the three treatments with NPV compared to watersheds with row crops. We observed a progressively greater reduction across the 3 years of the study as the perennial strips became established with the greatest differences among treatments occurring in 2010. The differences among the watersheds were attributed mainly to NPV amount and position, with the 10% NPV at footslope treatment having the greatest runoff reduction probably because the portion of NPV filter strip that actually contacted watershed runoff was greater with the 10% NPV at footslope. We observed greater reductions in runoff in spring and fall likely because perennial prairie plants were active and crops were absent or not fully established. High antecedent soil moisture sometimes led to little benefit of the NPV treatments but in general the NPV treatments were effective during both small and large events. We conclude that, small amounts of NPV strategically incorporated into corn-soybean watersheds in the Midwest US can be used to effectively reduce runoff. (C) 2012 Elsevier B.V. All rights reserved.

Recent work has identified host and conspecific volatiles that mediate host- and mate-finding by D. abbreviatus. The interaction of light, color, and odors has not been studied in this species. The responses of male and female D. abbreviatus to narrow bandwidths of visible light emitted by LEDs offered alone and in combination with olfactory stimuli were studied in a specially-designed multiple choice arena combined with a locomotion compensator. Weevils were more attracted to wavelengths close to green and yellow compared with blue or ultraviolet, but preferred red and darkness over green. Additionally, dim green light was preferred over brighter green. Adult weevils were also attracted to the odor of its citrus host + conspecifics. However, the attractiveness of citrus + conspecific odors disappeared in the presence of a green light. Photic stimulation induced males but not females to increase their speed. In the presence of light emitted by LEDs, turning speed decreased and path straightness increased, indicating that weevils tended to walk less tortuously. Diaprepes abbreviatus showed a hierarchy between chemo- and photo-taxis in the series of experiments presented herein, where the presence of the green light abolished upwind anemotaxis elicited by the pheromone + host plant odor. Insight into the strong responses to visual stimuli of chemically stimulated insects may be provided when the amount of information supplied by vision and olfaction is compared, as the information transmission capacity of compound eyes is estimated to be several orders of magnitude higher compared with the olfactory system. Subordination of olfactory responses by photic stimuli should be considered in the design of strategies aimed at management of such insects.

Genome annotation depends on the availability of transcript information as well as orthology information. In teleost fish, genome annotation is seriously hindered by genome duplication. Because of gene duplications, one cannot establish orthologies simply by homology comparisons. Rather intense phylogenetic analysis or structural analysis of orthologies is required for the identification of genes. To conduct phylogenetic analysis and orthology analysis, full-length transcripts are essential. Generation of large numbers of full-length transcripts using traditional transcript sequencing is very difficult and extremely costly. Results: In this work, we took advantage of a doubled haploid catfish, which has two sets of identical chromosomes and in theory there should be no allelic variations. As such, transcript sequences generated from next-generation sequencing can be favorably assembled into full-length transcripts. Deep sequencing of the doubled haploid channel catfish transcriptome was performed using Illumina HiSeq 2000 platform, yielding over 300 million high-quality trimmed reads totaling 27 Gbp. Assembly of these reads generated 370,798 non-redundant transcript-derived contigs. Functional annotation of the assembly allowed identification of 25,144 unique protein-encoding genes. A total of 2,659 unique genes were identified as putative duplicated genes in the catfish genome because the assembly of the corresponding transcripts harbored PSVs or MSVs (in the form of pseudo-SNPs in the assembly). Of the 25,144 contigs with unique protein hits, around 20,000 contigs matched 50% length of reference proteins, and over 14,000 transcripts were identified as full-length with complete open reading frames. The characterization of consensus sequences surrounding start codon and the stop codon confirmed the correct assembly of the full-length transcripts. Conclusions: The large set of transcripts assembled in this study is the most comprehensive set of genome resources ever developed from catfish, which will provide the much needed resources for functional genome research in catfish, serving as a reference transcriptome for genome annotation, analysis of gene duplication, gene family structures, and digital gene expression analysis. The putative set of duplicated genes provide a starting point for genome scale analysis of gene duplication in the catfish genome, and should be a valuable resource for comparative genome analysis, genome evolution, and genome function studies.

Amount of SLS grafted based on phenol analysis was 0.5% and 1.0% in the absence and presence of 1-hydroxybenzotriazole (HBT), respectively. Starch-SLS graft copolymers were effective antioxidants as judged by 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The presence of laccase caused a reduction in starch molecular weight although a cross-linked gel fraction was also observed when HBT was present. This new method for preparing starch chemically modified with phenolic compounds is simple and the resulting antioxidant polymers have potential in food, cosmetic and packaging applications.

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

Also, frameworks that identify and map carbon stocks and corresponding forest management drivers using available regional, national, and international-level forest inventory datasets could provide insights into key forest structural characteristics and management practices that are optimal for carbon storage. To address this need we used publicly available USDA Forest Service Forest Inventory and Analysis data and spatial analyses to develop a framework for mapping "carbon hotspots" (i.e. areas of significantly high tree and understoly aboveground carbon stocks) across a range of forest types using the state of Florida, USA as an example. We also analyzed influential forest management variables (e.g. forest types, fire, hurricanes, tenure, management activities) using generalized linear mixed modeling to identify drivers associated with these hotspots. Most of the hotspots were located in the northern third of the state some in pen-urban areas, and there were no identifiable hotspots in South Florida. Forest silvicultural treatments (e.g. site preparation, thinning, logging, etc) were not significant predictors of hotspots. Forest types, site quality, and stand age were however significant predictors. Higher site quality and stand age increased the probability of forests being classified as a hotspot. Disturbance type and time since disturbance were not significant predictors in our analyses. This framework can use globally available forest inventory datasets to analyze and map ecosystems service provision areas and bioenergy supplies and identify forest management practices that optimize these services in forests.

TI Integrated watershed- and farm-scale modeling framework for targeting critical source areas while maintaining farm economic viability SO JOURNAL OF ENVIRONMENTAL MANAGEMENT LA English DT Article DE Farm profitability; Management practices; Model integration; Targeting; Water quality ID DISSOLVED PHOSPHORUS TRANSPORT; AGRICULTURAL WATERSHEDS; MANAGEMENT-PRACTICES; FORAGE MANAGEMENT; ASSESSMENT-TOOL; SWAT MODEL; RUNOFF; LEVEL; STRATEGIES; LANDSCAPE AB Quantitative risk assessments of pollution and data related to the effectiveness of mitigating best management practices (BMPs) are important aspects of nonpoint source pollution control efforts, particularly those driven by specific water quality objectives and by measurable improvement goals, such as the total maximum daily load (TMDL) requirements. Targeting critical source areas (CSAs) that generate disproportionately high pollutant loads within a watershed is a crucial step in successfully controlling nonpoint source pollution. The importance of watershed simulation models in assisting with the quantitative assessments of CSAs of pollution (relative to their magnitudes and extents) and of the effectiveness of associated BMPs has been well recognized. However, due to the distinct disconnect between the hydrological scale in which these models conduct their evaluation and the farm scale at which feasible BMPs are actually selected and implemented, and due to the difficulty and uncertainty involved in transferring watershed model data to farm fields, there are limited practical applications of these tools in the current nonpoint source pollution control efforts by conservation specialists for delineating CSAs and planning targeting measures. There are also limited approaches developed that can assess impacts of CSA-targeted BMPs on farm productivity and profitability together with the assessment of water quality improvements expected from applying these measures. This study developed a modeling framework that integrates farm economics and environmental aspects (such as identification and mitigation of CSAs) through joint use of watershed- and farm-scale models in a closed feedback loop. The integration of models in a closed feedback loop provides a way for environmental changes to be evaluated with regard to the impact on the practical aspects of farm management and economics, adjusted or reformulated as necessary, and revaluated with respect to effectiveness of environmental mitigation at the farm- and watershed-levels. This paper also outlines steps needed to extract important CSA-related information from a watershed model to help inform targeting decisions at the farm scale. The modeling framework is demonstrated with two unique case studies in the northeastern United States (New York and Vermont), with supporting data from numerous published, location-specific studies at both the watershed and farm scales. Using the integrated modeling framework, it can be possible to compare the costs (in terms of changes required in farm system components or financial compensations for retiring crop lands) and benefits (in terms of measurable water quality improvement goals) of implementing targeted BMPs. This multi-scale modeling approach can be used in the multi-objective task of mitigating CSAs of pollution to meet water quality goals while maintaining farm-level economic viability.

This relationship, if true, would indicate an additional role for nitrogen in the climate system via its influence on surface albedo and may offer a simple approach for monitoring foliar nitrogen using satellite data. We report, however, that the previously reported correlation is an artifact-it is a consequence of variations in canopy structure, rather than of %N. The data underlying this relationship were collected at sites with varying proportions of foliar nitrogen-poor needleleaf and nitrogen-rich broadleaf species, whose canopy structure differs considerably. When the BRF data are corrected for canopy-structure effects, the residual reflectance variations are negatively related to %N at all wavelengths in the interval 423-855 nm. This suggests that the observed positive correlation between BRF and %N conveys no information about %N. We find that to infer leaf biochemical constituents, e.g., N content, from remotely sensed data, BRF spectra in the interval 710-790 nm provide critical information for correction of structural influences. Our analysis also suggests that surface characteristics of leaves impact remote sensing of its internal constituents. This further decreases the ability to remotely sense canopy foliar nitrogen. Finally, the analysis presented here is generic to the problem of remote sensing of leaf-tissue constituents and is therefore not a specific critique of articles espousing remote sensing of foliar %N.

Recent efforts addressing critical interactions of rAd5 vectors with components of the bovine immune system have elucidated important aspects of induction of protective immunity against FMDV. In the current study, a rAd5-Luciferase (rAd5-Luc) surrogate vector was utilized for indirect assessment of rAd5-FMDV distribution during the first 48 hours post inoculation (hpi). To compare vector distribution dynamics and time-dependent transgene expression, bovine cells were inoculated in vitro with rAd5-FMDV and rAd5-Luc vectors. Superior transgene expression was detected in cells infected with rAd5-Luc compared to rAd5-FMDV. However, both vectors behaved remarkably similar in demonstrating elevated mRNA transcription at 24 and 48 hpi with peak occurrence of transgene expression at 48 hpi. Injection sites of cattle inoculated with rAd5-Luc contained mononuclear inflammatory infiltrates with hexon and transgene proteins associated with antigen-presenting cells. Luciferase activity, as well as microscopic detection of luciferase antigens, peaked at 24 hpi. Presence of viral mRNA also peaked at 24 hpi but unlike luciferase, remained strongly detected at 48 hpi. Cell-associated luciferase antigens were detected as early as 6 hpi at the cortical interfolicullar areas of local LN, indicating rapid trafficking of antigen-presenting cells to lymphoid tissues. This work provides mechanistic insights on rAd5-mediated immunity in cattle and will contribute to ongoing efforts to enhance rAd5-FMDV vaccine efficacy. (C) 2012 Elsevier B.V. All rights reserved.

TI Meta-Analysis Investigating Associations Between Healthy Diet and Fasting Glucose and Insulin Levels and Modification by Loci Associated With Glucose Homeostasis in Data From 15 Cohorts SO AMERICAN JOURNAL OF EPIDEMIOLOGY LA English DT Review DE diabetes; dietary pattern; gene-environment interaction; glucose; insulin ID CLINICAL RISK-FACTORS; ATHEROSCLEROSIS MESA; DAIRY CONSUMPTION; GENETIC-LOCI; DNA VARIANTS; FOOD SYNERGY; DESIGN; PATTERNS; WOMEN; OBJECTIVES AB Whether loci that influence fasting glucose (FG) and fasting insulin (FI) levels, as identified by genome-wide association studies, modify associations of diet with FG or FI is unknown. We utilized data from 15 US and European cohort studies comprising 51,289 persons without diabetes to test whether genotype and diet interact to influence FG or FI concentration. We constructed a diet score using study-specific quartile rankings for intakes of whole grains, fish, fruits, vegetables, and nuts/seeds (favorable) and red/processed meats, sweets, sugared beverages, and fried potatoes (unfavorable). We used linear regression within studies, followed by inverse-variance-weighted meta-analysis, to quantify 1) associations of diet score with FG and FI levels and 2) interactions of diet score with 16 FG-associated loci and 2 FI-associated loci. Diet score (per unit increase) was inversely associated with FG ( 0.004 mmol/L, 95 confidence interval: 0.005, 0.003) and FI ( 0.008 ln-pmol/L, 95 confidence interval: 0.009, 0.007) levels after adjustment for demographic factors, lifestyle, and body mass index. Genotype variation at the studied loci did not modify these associations. Healthier diets were associated with lower FG and FI concentrations regardless of genotype at previously replicated FG- and FI-associated loci. Studies focusing on genomic regions that do not yield highly statistically significant associations from main-effect genome-wide association studies may be more fruitful in identifying diet-gene interactions.

TI Near-optimal response of instantaneous transpiration efficiency to vapour pressure deficit, temperature and [CO2] in cotton (Gossypium hirsutum L.) SO AGRICULTURAL AND FOREST METEOROLOGY LA English DT Article DE Elevated temperature; Elevated [CO2]; Photosynthesis; Transpiration; Stomatal control ID WATER-USE EFFICIENCY; STOMATAL CONDUCTANCE; CARBON-DIOXIDE; ATMOSPHERIC CO2; BIOCHEMICAL-MODEL; CROP PRODUCTION; BOUNDARY-LAYER; GAS-EXCHANGE; ELEVATED CO2; C-3 PLANTS AB The instantaneous transpiration efficiency (ITE, the ratio of photosynthesis rate to transpiration) is an important variable for crops, because it ultimately affects dry mass production per unit of plant water lost to the atmosphere. The theory that stomata optimize carbon uptake per unit water used predicts that ITE should be proportional to the atmospheric [CO2] (C-a), approximately inversely proportional to the square root of the leaf-to-air vapour pressure deficit (D-s), and weakly dependent on leaf temperature (T-leaf). We measured the response of ITE to a range in D-s at constant air temperature (T-air), for two cultivars (DP16 and Sicot 71BRF) of cotton (Gossypium hirsutum L) grown in two C-a (400 and 640 mu l l(-1)) and two T-air (28 and 32 degrees C) treatments. To interpret responses of ITE to these variables, we used a model based on the assumption that stomata are regulated to optimize carbon uptake per unit water used. The measured ITE response to D-s was very close to that predicted by the model, but LIE was overpredicted at low D-s. We found that one model adequately fit all T-air and C-a treatments, and found no significant differences in the single parameter of the model with C-a, T-air, or cultivar. As predicted, ITE increased in proportion to C-a (a 51-64% increase in ITE compared to a 60% increase in C-a). Photosynthesis rate was 16-22% higher in the elevated T-air treatment, which led to a corresponding increase in transpiration rate at a given D-s, again as predicted. The results show that, in cotton, a straightforward framework based on optimal stomatal theory successfully predicted responses of ITE to D-s, T-air, and C-a. These findings greatly simplify modelling of an important component of crop water-use efficiency in response to climate change. (C) 2012 Elsevier B.V. All rights reserved.

TI Long-distance dispersal of spruce budworm (Choristoneura fumiferana Clemens) in Minnesota (USA) and Ontario (Canada) via the atmospheric pathway SO AGRICULTURAL AND FOREST METEOROLOGY LA English DT Article DE Spruce budworm; Choristoneura fumiferana; Long-distance dispersal; Aerobiology; Agent-based modeling ID POPULATION GENETIC-STRUCTURE; MOTH FLIGHT; NORTHERN MINNESOTA; MODELING SYSTEM; SOYBEAN RUST; LEPIDOPTERA; MIGRATION; OUTBREAKS; TORTRICIDAE; RADAR AB Dispersal can play an important role in the population dynamics of forest insects, but the role of long-distance immigration and emigration remains unclear due to the difficulty of quantifying dispersal distance and direction. We designed an agent-based spruce budworm flight behavior model that, when interfaced with temperature, wind speed, and precipitation output from a high-resolution atmospheric model, produces detailed flight trajectories and deposition patterns over large landscapes. Rules and relationships describing budworm adult (moth) lift-off, ascent, horizontal flight, and descent were parameterized using a detailed empirical study of budworm dispersal behavior and corresponding meteorological conditions during a 1970s outbreak in New Brunswick, Canada. Simulated moth landings were assumed to be dependent in part on the availability of suitable host tree species. We applied the model to a 6.4 million ha landscape at the border between northern Minnesota (USA) and Ontario (Canada) during an eight-day flight window in late June 2007. Specimens collected during and after this flight window indicated moths emerging from an inland source of outbreak populations dispersed over 150 km to trap sites near the north shore of Lake Superior, where localized cooling was predicted to have delayed emergence of locally-produced budworm moths. Simulations suggested immigration of moths to lakeshore sites from the outbreak source was plausible on three of eight dates within the flight window, but the relatively narrow deposition footprints implied immigration occurred on different dates across lakeshore sites. Apart from wind speed and direction, precipitation and low temperatures limited dispersal to substantially shorter distances for a few dates within the simulated flight window. Key uncertainties limiting our understanding of atmospheric transport of spruce budworm include behavioral responses to vertical heterogeneity in the air temperature profile, the precipitation threshold required for the forced descent of moths from the air column, and search mechanisms affecting host and/or mate location during long-distance flight.

Maize leaves provide a unique opportunity to study positional information. In the developing leaf primordium, a line is drawn across a field of seemingly identical cells. Above the line, the cells become blade, below the line the cells become sheath and at the line, the cells differentiate into the specialized tissues of ligule and auricle. We identified a new mutation, Liguleless narrow (Lgn), that affects this patterning and shows striking defects in lateral growth as well, thus linking proximal-distal patterning to medial-lateral growth. In characterizing the defect we discovered that both the auxin transport protein ZmPIN1a and the squamosa promoter-binding protein LIGULELESS1 are expressed precisely at this positionally cued line and are disrupted by Lgn. Positional cloning and a transposon-derived allele demonstrate that LGN is a kinase. These results suggest that LGN participates in setting up positional information through a signaling cascade. Interestingly, LGN has a paralog that is upregulated in the mutant, suggesting an important feedback mechanism involved in setting the positional boundary.

Mice were fed with the AIN93G control diet or with the diet supplemented with 2 or 4% curcumin for 5 weeks at which time they were injected subcutaneously with 2.5 x 10(5) viable LLC cells. The subcutaneous primary tumor was surgically removed when it reached similar to 8 mm in diameter, and the experiment was terminated 10 days after the surgery. There was no difference in pulmonary metastatic yield among the groups. Curcumin supplementation at either dietary level did not significantly increase the size of metastatic tumors; however, the combined data from both curcumin groups showed that curcumin treatment increased metastatic tumor cross-sectional area by 46% (p < 0.05) and volume by 70% (p < 0.05) compared to the controls. Curcumin supplementation increased plasma concentrations of angiogenic factors angiogenin (p < 0.05), basic fibroblast growth factor (p < 0.05) and vascular endothelial growth factor (p < 0.05), as well as inflammatory cytokines interleukin-1 beta (p < 0.05) and monocyte chemotactic protein-1 (p < 0.05), compared to the controls. These results demonstrate that curcumin does not prevent metastasis and indicate that it can enhance metastatic growth of LLC in mice, perhaps through upregulation of angiogenesis and inflammation.

The disease begins when exotic beech scale insects feed on the bark of trees, and is followed by infection of damaged bark tissues by one of the Neonectria species of fungi. Proteomic analysis was conducted of beech bark proteins from diseased trees and healthy trees in areas heavily infested with beech bark disease. All of the diseased trees had signs of Neonectria infection such as cankers or fruiting bodies. In previous tests reported elsewhere, all of the diseased trees were demonstrated to be susceptible to the scale insect and all of the healthy trees were demonstrated to be resistant to the scale insect. Sixteen trees were sampled from eight geographically isolated stands, the sample consisting of 10 healthy (scale-resistant) and 6 diseased/infested (scale-susceptible) trees. Results: Proteins were extracted from each tree and analysed in triplicate by isoelectric focusing followed by denaturing gel electrophoresis. Gels were stained and protein spots identified and intensity quantified, then a statistical model was fit to identify significant differences between trees. A subset of BBD differential proteins were analysed by mass spectrometry and matched to known protein sequences for identification. Identified proteins had homology to stress, insect, and pathogen related proteins in other plant systems. Protein spots significantly different in diseased and healthy trees having no stand or disease-by-stand interaction effects were identified. Conclusions: Further study of these proteins should help to understand processes critical to resistance to beech bark disease and to develop biomarkers for use in tree breeding programs and for the selection of resistant trees prior to or in early stages of BBD development in stands. Early identification of resistant trees (prior to the full disease development in an area) will allow forest management through the removal of susceptible trees and their root-sprouts prior to the onset of disease, allowing management and mitigation of costs, economic impact, and impacts on ecological systems and services.

TI Histological Analysis and 3D Reconstruction of Winter Cereal Crowns Recovering from Freezing: A Unique Response in Oat (Avena sativa L.) SO PLOS ONE LA English DT Article ID LOW-TEMPERATURE; INJURY; TOLERANCE; BARLEY; GENES; PLANT; ACCLIMATION; ARABIDOPSIS; MICROSCOPY; TRANSPORT AB The crown is the below ground portion of the stem of a grass which contains meristematic cells that give rise to new shoots and roots following winter. To better understand mechanisms of survival from freezing, a histological analysis was performed on rye, wheat, barley and oat plants that had been frozen, thawed and allowed to resume growth under controlled conditions. Extensive tissue disruption and abnormal cell structure was noticed in the center of the crown of all 4 species with relatively normal cells on the outside edge of the crown. A unique visual response was found in oat in the shape of a ring of cells that stained red with Safranin. A tetrazolium analysis indicated that tissues immediately inside this ring were dead and those outside were alive. Fluorescence microscopy revealed that the barrier fluoresced with excitation between 405 and 445 nm. Three dimensional reconstruction of a cross sectional series of images indicated that the red staining cells took on a somewhat spherical shape with regions of no staining where roots entered the crown. Characterizing changes in plants recovering from freezing will help determine the genetic basis for mechanisms involved in this important aspect of winter hardiness.

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

TI Exposure of RML scrapie agent to a sodium percarbonate-based product and sodium dodecyl sulfate renders PrPSc protease sensitive but does not eliminate infectivity SO BMC VETERINARY RESEARCH LA English DT Article DE Inactivation; Prion; Scrapie; Sodium dodecyl sulfate; Sodium percarbonate ID BOVINE SPONGIFORM ENCEPHALOPATHY; CREUTZFELDT-JAKOB DISEASE; PRION PROTEIN; ADAPTED SCRAPIE; VARIANT CJD; INACTIVATION; BRAIN; STRAIN; MICE; VIRUS AB Background: Prions, the causative agents of the transmissible spongiform encephalopathies, are notoriously difficult to inactivate. Current decontamination recommendations by the World Health Organization include prolonged exposure to 1 N sodium hydroxide or > 20,000 ppm sodium hypochlorite, or autoclaving. For decontamination of large stainless steel surfaces and equipment as in abattoirs, for example, these methods are harsh or unsuitable. The current study was designed to evaluate the effectiveness of a commercial product containing sodium percarbonate to inactivate prions. Samples of mouse brain infected with a mouse-adapted strain of the scrapie agent (RML) were exposed to a sodium percarbonate-based product (SPC-P). Treated samples were evaluated for abnormal prion protein (PrPSc)-immunoreactivity by western blot analysis, and residual infectivity by mouse bioassay. Results: Exposure to a 21% solution of SPC-P or a solution containing either 2.1% or 21% SPC-P in combination with sodium dodecyl sulfate (SDS) resulted in increased proteinase K sensitivity of PrPSc. Limited reductions in infectivity were observed depending on treatment condition. A marginal effect on infectivity was observed with SPC-P alone, but an approximate 2-3 log(10) reduction was observed with the addition of SDS, though exposure to SDS alone resulted in an approximate 2 log(10) reduction. Conclusions: This study demonstrates that exposure of a mouse-adapted scrapie strain to SPC-P does not eliminate infectivity, but does render PrPSc protease sensitive.

Dvorak, Jan TI Insular Organization of Gene Space in Grass Genomes SO PLOS ONE LA English DT Article ID ARABIDOPSIS-THALIANA; MAIZE GENOME; ORYZA-SATIVA; WHEAT; EVOLUTION; SEQUENCE; RECOMBINATION; ISLANDS; REGIONS; PLANTS AB Wheat and maize genes were hypothesized to be clustered into islands but the hypothesis was not statistically tested. The hypothesis is statistically tested here in four grass species differing in genome size, Brachypodium distachyon, Oryza sativa, Sorghum bicolor, and Aegilops tauschii. Density functions obtained under a model where gene locations follow a homogeneous Poisson process and thus are not clustered are compared with a model-free situation quantified through a non-parametric density estimate. A simple homogeneous Poisson model for gene locations is not rejected for the small O. sativa and B. distachyon genomes, indicating that genes are distributed largely uniformly in those species, but is rejected for the larger S. bicolor and Ae. tauschii genomes, providing evidence for clustering of genes into islands. It is proposed to call the gene islands "gene insulae" to distinguish them from other types of gene clustering that have been proposed. An average S. bicolor and Ae. tauschii insula is estimated to contain 3.7 and 3.9 genes with an average intergenic distance within an insula of 2.1 and 16.5 kb, respectively. Inter-insular distances are greater than 8 and 81 kb and average 15.1 and 205 kb, in S. bicolor and Ae. tauschii, respectively. A greater gene density observed in the distal regions of the Ae. tauschii chromosomes is shown to be primarily caused by shortening of inter-insular distances. The comparison of the four grass genomes suggests that gene locations are largely a function of a homogeneous Poisson process in small genomes. Nonrandom insertions of LTR retroelements during genome expansion creates gene insulae, which become less dense and further apart with the increase in genome size. High concordance in relative lengths of orthologous intergenic distances among the investigated genomes including the maize genome suggests functional constraints on gene distribution in the grass genomes.

TI Terrestrial vegetation and aquatic chemistry influence larval mosquito abundance in catch basins, Chicago, USA SO PARASITES & VECTORS LA English DT Article DE Culex mosquitoes; Larval habitat; Landscape ecology; Vegetation; Aquatic chemistry; Geographic information science; West Nile virus ID WEST-NILE-VIRUS; NORTHEASTERN UNITED-STATES; CULEX-PIPIENS DIPTERA; TREE-HOLE ECOSYSTEMS; LEAF DETRITUS; SPATIAL-DISTRIBUTION; AEDES-TRISERIATUS; SUBURBAN CHICAGO; BREEDING SITES; BRIDGE VECTOR AB Background: An important determinant of mosquito-borne pathogen transmission is the spatial distribution of vectors. The primary vectors of West Nile virus (WNV) in Illinois are Culex pipiens Linnaeus (Diptera: Culicidae) and Culex restuans Theobald. In urban environments, these mosquitoes commonly oviposit in roadside storm water catch basins. However, use of this habitat is inconsistent, with abundance of larvae varying significantly across catch basins at a fine spatial scale. Methods: We tested the hypothesis that attributes of the biotic and abiotic environment contribute to spatial and temporal variation in production of mosquito vectors, characterizing the relationship between terrestrial vegetation and aquatic chemistry and Culex abundance in Chicago, Illinois. Larvae were sampled from 60 catch basins from June 14 to October 3, 2009. Density of shrubs and 14 tree genera surrounding the basins were quantified, as well as aquatic chemistry content of each basin. Results: We demonstrate that the spatial pattern of Culex abundance in catch basins is strongly influenced by environmental characteristics, resulting in significant variation across the urban landscape. Using regression and machine learning techniques, we described landscape features and microhabitat characteristics of four Chicago neighborhoods and examined the implications of these measures for larval abundance in adjacent catch basins. The important positive predictors of high larval abundance were aquatic ammonia, nitrates, and area of shrubs of height <1 m surrounding the catch basins, whereas pH and area of flowering shrub were negatively correlated with larval abundance. Tree density, particularly of arborvitae, maple, and pear, also positively influenced the distribution of Culex during the fruit-bearing periods and early senescent periods in August and September. Conclusions: This study identifies environmental predictors of mosquito production in urban environments. Because an abundance of adult Culex is integral to efficient WNV transmission and mosquitoes are found in especially high densities near larval habitats, identifying aquatic sites for Culex and landscape features that promote larval production are important in predicting the spatial pattern of cases of human and veterinary illness. Thus, these data enable accurate assessment of regions at risk for exposure to WNV and aid in the prevention of vector-borne disease transmission.

TI Gain-of-Function Lipoprotein Lipase Variant rs13702 Modulates Lipid Traits through Disruption of a MicroRNA-410 Seed Site SO AMERICAN JOURNAL OF HUMAN GENETICS LA English DT Article ID GENOME-WIDE ASSOCIATION; CORONARY-HEART-DISEASE; MESSENGER-RNA TRANSLATION; UNTRANSLATED REGION; GENE-EXPRESSION; ADIPOSE-TISSUE; LOCI; RISK; POLYMORPHISMS; GWAS AB Genome-wide association studies (GWAS) have identified hundreds of genetic variants that are associated with lipid phenotypes. However, data supporting a functional role for these variants in the context of lipid metabolism are scarce. We investigated the association of the lipoprotein lipase (LPL) variant rs13702 with plasma lipids and explored its potential for functionality The rs13702 minor allele had been predicted to disrupt a microRNA (miR) recognition element (MRE) seed site (MRESS) for the human microRNA-410 (miR-410). Furthermore, rs13702 is in linkage disequilibrium (LD) with several SNPs identified by GWAS. We performed a meta-analysis across ten cohorts of participants that showed a statistically significant association of rs13702 with triacylglycerols (TAG) (p = 3.18 x 10(-42))and high-density lipoprotein cholesterol (HDL-C) (p = 1.35 x 10(-32)) with each copy of the minor allele associated with 0.060 mmol/l lower TAG and 0.041 mmol/l higher HDL-C. Our data showed that an LPL 3' UTR luciferase reporter carrying the rs13702 major T allele was reduced by 40% in response to a miR-410 mimic. We also evaluated the interaction between intake of dietary fatty acids and rs13702. Meta-analysis demonstrated a significant interaction between rs13702 and dietary polyunsaturated fatty acid (PUFA) with respect to TAG concentrations (p = 0.00153), with the magnitude of the inverse association between dietary PUFA intake and TAG concentration showing -0.007 mmol/l greater reduction. Our results suggest that rs13702 induces the allele-specific regulation of LPL by miR-410 in humans. This work provides biological and potential clinical relevance for previously reported GWAS variants associated with plasma lipid phenotypes.

The winter range of Bicknell's Thrush (Catharus bicknelli), a threatened Nearctic-Neotropical migratory songbird, is restricted to the Greater Antilles. We analyzed winter records from the mid-1970s to 2009 to quantitatively evaluate winter distribution and habitat selection. Additionally, we conducted targeted surveys in Jamaica (n = 433), Cuba (n = 363), Dominican Republic (n = 1,000), Haiti (n = 131) and Puerto Rico (n = 242) yielding 179 sites with thrush presence. We modeled Bicknell's Thrush winter habitat selection and distribution in the Greater Antilles in Maxent version 3.3.1. using environmental predictors represented in 30 arc second study area rasters. These included nine landform, land cover and climatic variables that were thought a priori to have potentially high predictive power. We used the average training gain from ten model runs to select the best subset of predictors. Total winter precipitation, aspect and land cover, particularly broadleaf forests, emerged as important variables. A five-variable model that contained land cover, winter precipitation, aspect, slope, and elevation was the most parsimonious and not significantly different than the models with more variables. We used the best fitting model to depict potential winter habitat. Using the 10 percentile threshold (>0.25), we estimated winter habitat to cover 33,170 km 2, nearly 10% of the study area. The Dominican Republic contained half of all potential habitat (51%), followed by Cuba (15.1%), Jamaica (13.5%), Haiti (10.6%), and Puerto Rico (9.9%). Nearly one-third of the range was found to be in protected areas. By providing the first detailed predictive map of Bicknell's Thrush winter distribution, our study provides a useful tool to prioritize and direct conservation planning for this and other wet, broadleaf forest specialists in the Greater Antilles.

Some studies have suggested that vitamin D may protect against structural progression. Objective To determine whether vitamin D supplementation reduces symptom and structural progression of knee OA. Design, Setting, and Patients A 2-year randomized, placebo-controlled, double-blind, clinical trial involving 146 participants with symptomatic knee OA (mean age, 62.4 years [SD, 8.5]; 57 women [61%], 115 white race [79%]). Patients were enrolled at Tufts Medical Center in Boston between March 2006 and June 2009. Intervention Participants were randomized to receive either placebo or oral cholecalciferol, 2000 IU/d, with dose escalation to elevate serum levels to more than 36 ng/mL. Main Outcome Measures Primary outcomes were knee pain severity (Western Ontario and McMaster Universities [WOMAC] pain scale, 0-20: 0, no pain; 20, extreme pain), and cartilage volume loss measured by magnetic resonance imaging. Secondary end points included physical function, knee function (WOMAC function scale, 0-68: 0, no difficulty; 68, extreme difficulty), cartilage thickness, bone marrow lesions, and radiographic joint space width. Results Eighty-five percent of the participants completed the study. Serum 25-hydroxyvitamin D levels increased by a mean 16.1 ng/mL (95% CI, 13.7 to 18.6) in the treatment group and by a mean 2.1 mg/mL (95% CI, 0.5 to 3.7) (P < .001) in the placebo group. Baseline knee pain was slightly worse in the treatment group (mean, 6.9; 95% CI, 6.0 to 7.7) than in the placebo group (mean, 5.8; 95% CI, 5.0 to 6.6) (P=.08). Baseline knee function was significantly worse in the treatment group (mean, 22.7; 95% CI, 19.8 to 25.6) than in the placebo group (mean, 18.5; 95% CI, 15.8 to 21.2) (P=.04). Knee pain decreased in both groups by a mean -2.31 (95% CI, -3.24 to -1.38) in the treatment group and -1.46 (95% CI, -2.33 to -0.60) in the placebo group, with no significant differences at any time. The percentage of cartilage volume decreased by the same extent in both groups (mean, -4.30; 95% CI, -5.48 to -3.12 vs mean, -4.25; 95% CI, -6.12 to -2.39) (P=.96). There were no differences in any of the secondary clinical end points. Conclusion and Relevance Vitamin D supplementation for 2 years at a dose sufficient to elevate 25-hydroxyvitamin D plasma levels to higher than 36 ng/mL, when compared with placebo, did not reduce knee pain or cartilage volume loss in patients with symptomatic knee OA.

Target analytes were extracted in acetonitrile/1.5% trifluoroacetic acid/NaCl, cleaned up by dispersive liquid-liquid microextraction (DLLME), and finally detected by terbium-sensitized luminescence (TSL) using a time-resolved luminescence photometer. CIPRO yielded slightly lower TSL response than ENRO, so a common threshold was derived from CIPRO and applied to both fluoroquinolones. Among 37 samples randomly spiked with CIPRO or ENRO up to 1 mu g/g, all 19 samples spiked above the 500 ng/g tolerance were correctly screened as positive with no false negatives, but 3 of 18 samples spiked below 500 ng/g were classified as positive. This method minimized the use of chlorinated solvents and significantly improved sample throughput. C1 [Chen, Guoying] ARS, Eastern Reg Res Ctr, USDA, Wyndmoor, PA 19038 USA.

TI Estimation of Cellulose Crystallinity of Lignocelluloses Using Near-IR FT-Raman Spectroscopy and Comparison of the Raman and Segal-WAXS Methods SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE cellulose crystallinity; Raman; WAXS; wood; lignocellulose; lignin ID INFRARED-SPECTROSCOPY; ENZYMATIC-HYDROLYSIS; WOOD; HEMICELLULOSE; DIMENSIONS; SPECTRA; FIBERS; LIGNIN AB Of the recently developed univariate and multivariate near-IR FT-Raman methods for estimating cellulose crystallinity, the former method was applied to a variety of lignocelluloses: softwoods, hardwoods, wood pulps, and agricultural residues/fibers. The effect of autofluorescence on the crystallinity estimation was minimized by solvent extraction or chemical treatment or both. Additionally, when the roles of lignin and hemicellulose in the Raman crystallinity assessment were investigated, it was found that syringyl lignin containing lignocelluloses generated somewhat higher crystallinity, whereas the presence of hemicellulose reduced the crystallinity. Overall, when autofluorescence was minimized and corrections made for hemicellulose and syringyl lignin contributions, the univariate Raman method performed well and estimated cellulose crystallinity accurately. Moreover, when the Raman and Segal-WAXS methods were compared, we observed that in the absence of significant fluorescence, the Raman method was influenced mostly by hemicellulose and syringyl lignin, whereas the Segal-WAXS was affected by various types of lignin and hemicellulose. It was concluded that the near-IR FT-Raman method with corrections for influences of syringyl lignin and hemicellulose can be used to correctly estimate cellulose crystallinity.

TI Evaluation of drought indices via remotely sensed data with hydrological variables SO JOURNAL OF HYDROLOGY LA English DT Article DE Drought; Soil moisture; Streamflow; Evaporative Stress Index (ESI); Palmer Drought Severity Index (PDSI); Vegetation Health Index (VHI) ID STANDARDIZED PRECIPITATION INDEX; SOIL-MOISTURE; AMSR-E; MODEL; SCALES; CLIMATE; REGIONS; FLUXES; SPACE; NDVI AB An intercomparison among standard and remotely sensed drought indices was conducted using streamflow and soil moisture measurements collected in the Little River Experimental Watershed, Georgia, US, during the period from 2000 to 2008. All drought indices exhibited a linear, monotonic association with soil moisture, but there was a non-linear monotonic association between the drought indices and streamflow. Of the indices examined, the Evaporative Stress Index (ESI) showed reasonable performance with about 90% accuracy capturing moderate drought conditions and 80% accuracy capturing severe drought conditions in comparison to observed soil moisture and streamflow. While the ability of the ESI to capture shorter term droughts is equal or superior to the Palmer Drought Severity Index (PDSI) when characterizing droughts based on soil moisture and streamflow thresholds, the accuracy of the ESI was less efficient in the case of severe droughts. A drought index developed from the Advanced Microwave Scanning Radiometer (AMSR-E) soil moisture product showed reasonable correlations with the observed soil moisture and streamflow. However the ESI, Vegetation Health Index (VHI), and PDSI demonstrated greater skill in detecting drought in this study region. Multi-variable linear regression models revealed that the joint use of PDSI and appropriate remote sensing products improved predictions of observed hydrologic variables. Overall, the ESI was identified as a promising drought index for characterizing streamflow and soil moisture anomalies, particularly in regions where precipitation observations are unavailable, sparsely distributed, or biased with respect to regional averages.

Daren TI Shrink-swell behavior of soil across a Vertisol catena SO JOURNAL OF HYDROLOGY LA English DT Article DE Soil subsidence; Soil water; Vertisol; Catena; Cracks ID TEXAS BLACKLAND PRAIRIE; HEAVY CLAY SOIL; LINEAR EXTENSIBILITY; CRACKING; RUNOFF; MODEL; INDEX AB An accurate estimate of the degree of soil cracking is important in partitioning rainfall into soil infiltration and runoff in watersheds with clay soils that shrink and swell. Usually in the application of surface hydrology models, cracking is considered to be predicted by assuming equidimensional shrinkage and a 1:3 ratio of change in soil profile thickness to depth of water loss. Our objective was to use in situ measurements of soil profile subsidence with loss of water in an apparently uniform Vertisol to determine: (1) whether or not the soil profile subsidence followed the 1:3 ratio of change in thickness to depth of water loss and (2) how the ratio of subsidence to water loss varies with the Coefficient of Linear Extensibility (COLE). The research was conducted on a catena of Houston Black and Heiden clays. Vertical soil shrinkage and swelling along with soil water content were measured at the summit, shoulder, backslope, and footslope positions of the catena. Change in soil water content along with spatial variability in COLE were the primary drivers of temporal and spatial variability of shrinkage and swelling on the catena. The rate that soil shrank or swelled with change in the amount of water stored in the soil was related to COLE, which was negatively correlated with carbonate content of the soil. Shrinkage of the soil profile with water lost was less than the commonly used 1:3 ratio. Our data supported using COLE to predict the degree to which the ratio is less than 1:3. Incorporating COLE values into a hydrology model to simulate soil shrinkage with water loss is a useful approach because COLE values have been measured for soils with shrink-swell potential and that data is available in USDA NRCS Soil Survey databases.

We focus on a partially observed cattle movement network in the U.S. and present a method for scaling up to a full network based on Bayesian inference, with the aim of informing epidemic disease spread models in the United States. The observed network is a 10% state stratified sample of Interstate Certificates of Veterinary Inspection that are required for interstate movement; describing approximately 20,000 movements from 47 of the contiguous states, with origins and destinations aggregated at the county level. We address how to scale up the 10% sample and predict unobserved intrastate movements based on observed movement distances. Edge prediction based on a distance kernel is not straightforward because the probability of movement does not always decline monotonically with distance due to underlying industry infrastructure. Hence, we propose a spatially explicit model where the probability of movement depends on distance, number of premises per county and historical imports of animals. Our model performs well in recapturing overall metrics of the observed network at the node level (U.S. counties), including degree centrality and betweenness; and performs better compared to randomized networks. Kernel generated movement networks also recapture observed global network metrics, including network size, transitivity, reciprocity, and assortativity better than randomized networks. In addition, predicted movements are similar to observed when aggregated at the state level (a broader geographic level relevant for policy) and are concentrated around states where key infrastructures, such as feedlots, are common. We conclude that the method generally performs well in predicting both coarse geographical patterns and network structure and is a promising method to generate full networks that incorporate the uncertainty of sampled and unobserved contacts.

The method was based on a QuEChERS (quick, easy, cheap, effective, rugged, safe) extraction with acetonitrile and dispersive solid-phase extraction (d-SPE) clean-up with zirconium-based sorbent prior to LP-GC/MS-MS analysis. The developed method was evaluated at 4 spiking levels and further validated by analysis of NIST Standard Reference Materials (SRMs) 19748 and 1947. Sample preparation for a batch of 10 homogenized samples took about 1 h/analyst, and LP-GC/MS-MS analysis provided fast separation of multiple analytes within 9 min achieving high throughput. With the use of isotopically labeled internal standards, recoveries of all but one analyte were between 70 and 120% with relative standard deviations less than 20% (n = 5). The measured values for both SRMs agreed with certified/reference values (72-119% accuracy) for the majority of analytes. The detection limits were 0.1-0.5 ngg(-1) for PCBs, 0.510 ngg(-1) for PBDEs, 0.5-5 ngg(-1) for select pesticides and PAHs and 1-10 ngg(-1) for flame retardants. The developed method was successfully applied for analysis of catfish samples from the market. Published by Elsevier B.V.

Within the animal host, the a(v)beta(6) interaction is believed to be the most relevant. Sub-neutralizing levels of soluble secreted a(v)beta(6) (ssa(v)beta(6)) was used as a selective pressure during passages in vitro to explore the plasticity of that interaction. Results: Genetically stable soluble integrin resistant (SIR) FMDV mutants derived from A24 Cruzeiro were selected after just 3 passages in cell culture in the presence of sub-neutralizing levels of ssa(v)beta(6). SIR mutants were characterized by: replication on selective cell lines, plaque morphology, relative sensitivity to ssa(v)beta(6) neutralization, relative ability to utilize a(v)beta(6) for infection, as well as sequence and structural changes. All SIR mutants maintained an affinity for a(v)beta(6). Some developed the ability to attach to cells expressing heparan sulfate (HS) proteoglycan, while others appear to have developed affinity for a still unknown third receptor. Two classes of SIR mutants were selected that were highly or moderately resistant to neutralization by ssa(v)beta(6). Highly resistant mutants displayed a G145D substitution (RGD to RDD), while moderately resistant viruses exhibited a L150P/R substitution at the conserved RGD + 4 position. VP1 G-H loop homology models for the A-type SIR mutants illustrated potential structural changes within the integrin-binding motif by these 2 groups of mutations. Treatment of O1 Campos with ssa(v)beta(6) resulted in 3 SIR mutants with a positively charged VP3 mutation allowing for HS binding. Conclusions: These findings illustrate how FMDV particles rapidly gain resistance to soluble receptor prophylactic measures in vitro. Two different serotypes developed distinct capsid mutations to circumvent the presence of sub-neutralizing levels of the soluble cognate receptor, all of which resulted in a modified receptor tropism that expanded the cell types susceptible to FMDV. The identification of some of these adaptive mutations in known FMDV isolates suggests these findings have implications beyond the cell culture system explored in these studies.

TI Epigenetic Modifications Unlock the Milk Protein Gene Loci during Mouse Mammary Gland Development and Differentiation SO PLOS ONE LA English DT Article ID BETA-GLOBIN LOCUS; DNA METHYLATION; CHROMATIN-STRUCTURE; TRANSGENIC MICE; HUMAN GENOME; CASEIN GENE; CELL-FATE; TRANSCRIPTION FACTORS; SECRETORY ACTIVATION; REGULATORY ELEMENTS AB Background: Unlike other tissues, development and differentiation of the mammary gland occur mostly after birth. The roles of systemic hormones and local growth factors important for this development and functional differentiation are well-studied. In other tissues, it has been shown that chromatin organization plays a key role in transcriptional regulation and underlies epigenetic regulation during development and differentiation. However, the role of chromatin organization in mammary gland development and differentiation is less well-defined. Here, we have studied the changes in chromatin organization at the milk protein gene loci (casein, whey acidic protein, and others) in the mouse mammary gland before and after functional differentiation. Methodology/Principal Findings: Distal regulatory elements within the casein gene cluster and whey acidic protein gene region have an open chromatin organization after pubertal development, while proximal promoters only gain open-chromatin marks during pregnancy in conjunction with the major induction of their expression. In contrast, other milk protein genes, such as alpha-lactalbumin, already have an open chromatin organization in the mature virgin gland. Changes in chromatin organization in the casein gene cluster region that are present after puberty persisted after lactation has ceased, while the changes which occurred during pregnancy at the gene promoters were not maintained. In general, mammary gland expressed genes and their regulatory elements exhibit developmental stage- and tissue-specific chromatin organization. Conclusions/Significance: A progressive gain of epigenetic marks indicative of open/active chromatin on genes marking functional differentiation accompanies the development of the mammary gland. These results support a model in which a chromatin organization is established during pubertal development that is then poised to respond to the systemic hormonal signals of pregnancy and lactation to achieve the full functional capacity of the mammary gland.

Forest managers need accurate information on beetle-induced tree mortality to make better decisions on how best to remediate beetle-killed forests and restore healthy ecosystem services. We applied the LandTrendr analysis tool, which can detect beetle-induced tree mortality, to Landsat image time series (1984-2010) at study areas affected by bark beetles in Oregon, Alaska, Idaho, Colorado, and Arizona. LandTrendr outputs indicating the timing, magnitude, and duration of disturbance events were generated consistently in all study areas considered and were used to predict Dead Basal Area (BA), Live BA, Total BA, and Percent Dead BA, as summarized from field plot observations geolocated within each study area, using The Random Forest (RF) classification and regression tree algorithm. RF models explained 11-53, 15-55, 11-47, and 17-56% of variance in total, live, dead, and %dead BA, respectively. RF models based on plots from all study areas explained 42, 30, 47, and 51% of variance in total, live, dead, and %dead BA, respectively. This was generally higher than the variance explained within a single study area. These results demonstrate potential for applying LandTrendr for mapping the timing, duration, spatial extent, and magnitude of bark beetle infestations from the historical Landsat image record, which would help forest scientists and managers to better map and monitor beetle effects on coniferous forests and manage their recovery.

This paper will focus on the sorption process, which can directly or indirectly control transformation and transport processes. Most commonly, aging effects have been characterized by batch equilibration and batch sequential extraction methods, in which changes in sorption coefficients (i.e. K-d) are determined for the chemical remaining after a given equilibration or incubation period. Alternative innovative methods to determine aging effects include isotopic exchange and supercritical fluid extractionmethods. K-d values have generally been shown to increase with aging time. The mechanisms that result in aging effects on sorption in soils can be artifacts of the methodology used to characterize sorption, or changes in chemical or physical processes, or a combination of these processes, all of which may affect the retention or sorption/desorption of the chemical in soil, which in turn affects pesticide transport and transformation. Regardless of the mechanisms involved in aging, observed increases in sorption during pesticide aging should be taken into account during characterization of the sorption process for mathematical models of pesticide transport. Potential transport of the pesticide would be over predicted if freshly treated soil K-d values were used to predict transport. The question of whether increases in sorption with aging affect degradation is still unanswered. C1 [Cheng, H. H.] ARS, USDA, St Paul, MN 55108 USA.

A typical cover crop utilized in the Southern United States is cereal rye (Secale cereale. L.). Tall cover crops such as cereal rye if not properly managed will lodge in different directions and thereby create planting problems of a cash crop due to interference of residue with seed planting equipment. Rolling/crimping is a mechanical method used to terminate a cover crop three weeks prior planting a cash crop. Original rollers were not widely adopted in the US because of increased roller vibration associated with high operating speeds. Research using new roller designs has demonstrated effectiveness at cover crop termination without generating harmful vibrations. Since US farming encompasses large and small scale production systems, several types of roller/crimpers were developed to accommodate both large row crops and small vegetable no-till and organic farm systems. The spiral roller/crimper design did not generate adequate crimping force to sufficiently injure cover crops compared to other newer concepts. A roller/crimper for raised beds was formulated to manage cover crops on elevated row culture systems and terminate cover crops both on row-tops and in furrows. The smooth roller with crimping bar assembly and the two stage roller/crimper were developed to operate with various tractors and also designed to apply herbicide as a supplement to rolling. With these rollers, the crimping force can be adjusted by altering spring tension to obtain the proper crimping force for a particular cover crop. In no-till vegetable and organic production systems, field operations may be conducted on small beds. Because of this constraint a new powered roller/crimper for small walk-behind tractors was developed which allows growers to successfully manage cover crops. Generally, the new roller designs were very effective at terminating rye cover crops.

This practice led to the development of landrace meta-populations of wheat and the emergence of farmers' seed systems through which they accessed and exchanged diverse genetic material. During the last 50 years, the introduction of high-yielding wheat varieties into, and the structural changes in wheat farming systems in developing countries, led to the loss of genetic diversity and fragmentation of meta-population structures of wheat landraces from large parts of the Fertile Crescent, the center of origin and diversity of wheat landraces. However, the persistence cultivation of some wheat landraces attests to their continued value to farmers, or to their competitive agronomic or nutritional advantage relative to modern varieties. For farmers to continue to grow, select, and manage local wheat landraces, and to reverse the fragmentation of their meta-populations, especially in their center of diversity, and allow evolutionary processes that mold landrace diversity to continue, their value should be raised to approximate or exceed the social value of high-yielding wheat varieties. This review provides information on wheat domestication and the origin of wheat landraces; their dynamic on-farm conservation and utilization in improving modern wheat cultivars and reversing the genetic erosion of wheat genetic diversity.

The PROSPECT model was calibrated to retrieve Chlorophyll content (Chl), Equivalent Water Thickness (EWT), and Leaf Mass per Area (LMA) of each leaf from hyperspectral reflectance spectra. The leaf stress conditions were then evaluated by examining the temporal variation of these biochemical constituents after glyphosate treatment. The approach was validated with in situ measured datasets. Results indicated that the coefficient of determination (R-2) of Chl, EWT, and LMA were greater than 0.8, 0.7, and 0.5, respectively, for both soybean and cotton. The Root-Mean-Square Error (RMSE) of Chl, EWT, and LMA were reasonably low with 1.2278 mu g/cm(2), 0.0005 g/cm(2), and 0.0042 g/cm(2) for soybean and 0.9144 mu g/cm(2), 0.0124 g/cm(2), and 0.0003 g/cm(2) for cotton, respectively. It was further found that the leaf injury caused by glyphosate treatments could be detected shortly after spraying by PROSPECT inversion for both soybean and cotton, with Chl of the higher dose solution treated leaves decreasing more rapidly compared with no glyphosate treated leaves, whereas the EWT and LMA showed no obvious difference between injured and healthy leaves. These findings demonstrate the feasibility of applying the PROSPECT inversion technique for the early detection of leaf injury from glyphosate and its potential for agricultural plant status monitoring.

An important potential application of UAS may be as a remote-sensing platform for precision agriculture, but simply down-scaling remote sensing methodologies developed using satellite and high-altitude aircraft platforms will create problems for data analysis. We simulated UAS image acquisition using both commercial and modified digital cameras mounted on an extension pole. The modified digital camera did not have an internal hot-mirror filter and had a red-cut filter to produce blue, green and near-infrared digital images. Green Normalized Difference Vegetation Indices from the modified camera was best for biomass and cover, whereas the blue, green and red digital cameras were better for estimating leaf chlorophyll content and nitrogen deficiency symptoms. The very small pixel sizes possible with UAS provide considerable information, but spectral methods of analysis are inadequate to extract the information. C1 [Hunt, E.

Better agricultural information is one of the key factors in understanding current trends and status that determine food security from local to global scales. Open-access policies for sharing geospatial information and technology are becoming an integral part of solving the food security equation. Geospatial technologies (remote sensing, global positioning system and geographical information system) have progressed rapidly in the 21st century, and will keep expanding to provide powerful tools in almost every aspect of food security, including research, development and aid delivery programs, policy, and outreach. Recent advances in Geoinformatics have created new opportunities to apply to agro-ecosystems research. The International Center for Agricultural Research in Dry Areas (ICARDA) is one of the research centers of the Consultative Group on International Agricultural Research (CGIAR). ICARDA works closely with national agricultural research programs and partners worldwide to develop new technological solutions to improve dryland agriculture and productivity to provide food security while protecting fragile ecosystems in those countries. It also leads the CGIAR Research Program (CRP) on Dryland Systems, which targets the poor and highly vulnerable populations of the dry areas. The CRP on Dryland Systems aims to develop technology, policy, and institutional innovations to improve food security and livelihoods using an integrated systems approach. The proposed presentation highlights the role of the Geoinformatics in ensuring global food security with special references to dryland agroecosystems.

Angular effects from wide swath remote sensing data have been observed. This paper examines the influence of angular effects on surface reflectance of typical surface and crop types for both narrow swath (e.g. Landsat) and wide swath (e.g. AWiFS) sensors. A bi-directional reflectance distribution function (BRDF) look-up table (LUT) for surface types from cropland data layer (CDL) was established. A LUT-based approach is proposed to correct angular effects for crops and natural vegetations. The angular corrected reflectance will provide a consistent data source for crop condition monitoring and long-term time-series analysis.

Cheese demand has been supplied by an industry that has developed technologies that facilitated production efficiency and fostered products of high and consistent quality. In addition to the changes within the production sector, changes in factors that affect cheese demand and how consumers obtain the food they desire have also occurred. Modern marketing and retailing of foods have helped create an away-from-home consuming public that has several alternatives for including cheese in the dining experience; the hamburger, pizza and Hispanic foods are prime examples. Also over time, there have been ongoing efforts to develop cheese products that meet the changing views as to what constitutes a healthy diet as exemplified by pursuit of low-fat and low-sodium products. It appears safe to say that cheese plays a major role in the economic situation of the dairy industry and in the nutritional profiles of the consuming public in the United States.

The highest quality kernels are cream colored, with 72 to 78% oil and 1.5% moisture. Two major quality defects of macadamias are kernel browning after roasting and off-flavor development caused by oxidation and rancidity during storage. Incremental drying to 1.5% kernel moisture content is critical to prevent kernel browning. Protection of the shelled nuts from moisture and oxygen during storage, delays rancidity and extends shelf-life. C1 ARS, USDA, Pacific Basin Agr Res Serv, Hilo, HI 96720 USA.

Processing plants reduce pathogen contamination with intervention strategies, yet foodborne illnesses still occur at an unacceptable frequency. Strategies are needed against pathogenic bacteria before they can enter processing facilities and the food chain. Reducing farm levels of zoonotic pathogens will enhance human health and food safety. Several pre-slaughter intervention strategies are under investigation: (1) direct anti-pathogen strategies, (2) competitive enhancement strategies and (3) animal management strategies. These include methods such as: vaccination against foodborne pathogenic bacteria, probiotics, prebiotics and competitive exclusion, using viruses to reduce pathogen populations, chemical methods and dietary changes.

Omic technologies analyze complete or nearly complete expressions of cell functions. DNA sequencing has resulted in complete genomes of foodborne pathogens. Omic-based technologies explore biological processes in a quantitative and integrative manner. They facilitate identification of genes and proteins that contribute to survival and persistence in food and other environments, that play a role in pathogenesis and that are targets for detection methods and control strategies.

Although often considered to be at low risk from alien plants, recent studies suggest that mountain ecosystems are not inherently more resistant to invasion than other types of ecosystems. Future invasion risks are likely to increase greatly, in particular due to climate warming and increased human land use (e. g. intensification of human activities, human population growth, and expansion of tourism). However, these risks can be reduced by minimising anthropogenic disturbance in and around protected areas, and by preventing the introduction of potentially invasive alien plants into these areas, particularly at high elevations. Sharing information and experiences gained in different mountainous areas is important for devising effective management strategies. We review current knowledge about plant invasions into mountains, assembling evidence from all continents and across different climate zones, and describe experiences at local to global scales in preventing and managing plant invasions into mountain protected areas. Our findings and recommendations are also relevant for managing native species that expand to higher elevations.

Serious management for protection of native biodiversity in Hawaii began in the 1970s, arguably at Hawaii Volcanoes National Park. Concerted alien plant management began there in the 1980s and has in a sense become a model for protected areas throughout Hawaii and Pacific Island countries and territories. We review the relative successes of their strategies and touch upon how their experience has been applied elsewhere. Protected areas in Hawaii are fortunate in having relatively good resources for addressing plant invasions, but many invasions remain intractable, and invasions from outside the boundaries continue from a highly globalised society with a penchant for horticultural novelty. There are likely few efforts in most Pacific Islands to combat alien plant invasions in protected areas, but such areas may often have fewer plant invasions as a result of their relative remoteness and/or socio-economic development status. The greatest current needs for protected areas in this region may be for establishment of yet more protected areas, for better resources to combat invasions in Pacific Island countries and territories, for more effective control methods including biological control programme to contain intractable species, and for meaningful efforts to address prevention and early detection of potential new invaders.

It is based on introduction of specialised natural enemies (herbivorous insects and fungal pathogens) from the weed's native range. It can be used safely if specialised natural enemies are selected and can be highly effective in suppressing weeds over large areas. Agents used in modern projects typically have genus or species level specificity and are safe when proper risk analysis and procedures are followed. Agents spread over large areas and can move into hard-to-reach areas. If correctly selected, agents are safe for use in areas too ecologically sensitive for chemical or mechanical control. Costs are independent of area to be treated because agents are self-reproducing, and results are self-sustaining. Biological control is most appropriate for use against widespread weeds, difficult to control with other methods that occur in critical habitats and damage biodiversity or ecosystem function. Finding suitable agents is easier against weeds distantly related to local native plants. Such targets reduce risk to native flora, facilitate agent screening, lower cost, and increase likelihood of success. Projects should be partnerships between biological control scientists and conservation biologists, and biological control activities should be done within a comprehensive restoration plan for the ecosystem. In some cases, suppression of the invasive weed may be sufficient, but sometimes additional actions, such as replanting native species or modifying ecosystem processes such as fire or flooding regimes may be essential.

Circulating serum AGP, but not haptoglobin, was higher (P < 0.001) in newborn runts than average-sized littermates. At 1 and 3 weeks, AGP and haptoglobin were similar among control and runt piglets. To determine the possible association between AGP and growth rate, blood was collected between the first and second day after birth in piglets from 10 average litters. Birthweight was positively correlated with growth rate through 21 days (linear regression correlation coefficient (CC), 0.43 (P < 0.006); 0.299 (P < 0.003) in males and females, respectively). Plasma AGP at birth was negatively correlated with growth (CC, -0.429 (P < 0.006); -0.351 (P < 0.01) in males and females, respectively). When AGP was calculated on a per kg birthweight basis, the CC with growth improved by 25 and 34% in males and females, respectively, compared with birthweight alone. Haptoglobin in blood was not correlated with growth. These data suggest that AGP at birth is reflective of growth conditions in utero or fetal maturation and may serve as an early predictive biomarker for pre-weaning growth rate.

It does not ignite easily, burns with a self-extinguishing flame, and forms a soft dissipating ash residue whereas synthetic fibers form a hard, molten bead residue with melt-drip behavior. Wool is preferred since it presents fewer hazards for industrial and military uses in furnishings and apparel. Many and varied chemistries were developed historically for improving fire performance of wool fibers. They include zirconium, phosphonate, halogenated compounds, generally applied by exhaust similar to conventional mordant dyeing. Increasing commercial demands coupled with environmental and toxicological concerns over the materials and treatments led to including high performance (HP) heat-resistant fibers in wool blended yarns and fabrics but with limitations including negative impact on fabric hand, dyeing, cost, and comfort. A novel HP poly-imidesiloxane (PISi) was synthesized for application to all-wool fabrics. Burning inhibition of PISi-treated wool as measured by char length, matched that of fabric blended of 50% wool, 48% Nomex (R), 1% Kevlar (R), 1% conducting fiber but PISi-treated wool was superior in maintaining a dissipating ash residue. A survey is provided of conventional and modern approaches to improving flame resistance (FR) of wool and wool blends. C1 ARS, USDA, Eastern Reg Res Ctr, Wyndmoor, PA 19038 USA.

Disorder development can also be enhanced using SmartFresh (TM) technology, based on the inhibition of ethylene perception by 1-methylcyclopropene (1-MCP). Injury development is associated with less mature fruit with lower ethylene production, but the aetiology of the disorder is poorly understood. Here we report on the progress made using mRNAseq approaches to explore the transcriptome during the development of external CO2 injury. Next-generation sequencing was used to mine the apple transcriptome for gene expression changes that are associated with the development of external CO2 injury. 'Empire' apples from a single orchard were treated with either 1 mu L L-1 1-MCP or 1 g L-1 diphenylamine or left untreated, and then stored in a CA of 5 kPa CO2 and 2 kPa O-2. In addition, susceptibility to the disorder in the 'Empire' apples from five different orchards was investigated and the methylation state of the ACS1 promoter investigated using McrBC endonuclease digestion and real-time quantitative polymerase chain reaction. Expression of over 30 000 genes, aligned to the apple genome, was monitored, with clear divergence of expression among treatments after 1 day of CA storage. Symptom development, internal ethylene concentrations (IECs) and methylation state of the ACS1 promoter were different for each of five orchards. With transcriptomic changes affected by treatment, this dataset will be useful in discovering biomarkers that assess disorder susceptibility. An inverse correlation between the frequency of this disorder and the IEC was detected in a multiple orchard trial. Differential methylation state of the ACS1 promoter correlated with both IEC and injury occurrence, indicating epigenetic regulation of ethylene biosynthesis and possibly events leading to disorder development.

A phage-based diagnostic assay was developed that detects and identifies P. cannabina pv alisalensis from cultures and diseased plant specimens. A recombinant "light-tagged" reporter phage was generated by integrating the luxAB genes into the P. cannabina pv alisalensis phage PBSPCA1 genome. PBSPCA1:: luxAB is viable, stable and detects P. cannabina pv alisalensis within minutes and with high sensitivity by conferring a bioluminescent signal. Detection is dependent on cell viability since cells treated with a bactericidal disinfectant are unable to elicit a signal. Importantly, the reporter phage detects P. cannabina pv alisalensis from diseased plant specimens indicating the potential of the diagnostic for disease identification. The reporter phage displays promise for the rapid and specific diagnostic detection of cultivated isolates, and infected plant specimens.

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

These three key plant species provide information required for the model to be used to classify seral stages and monitor trends based on index values (canopy cover (%) x frequency of occurrence (%)) of the three key plant species. The model is not linear and does not require a straight progression through all seral stages (plant phases) but may go through multiple states. Four seral stages (early to late plant succession) were quantitatively identified with an overall accuracy of seral stage assignment of 93%. All seral stages were significantly different (P = 0.001). Measurements of the three key plant species is all that is required for model prediction and classification of seral stages. C1 US Forest Serv, USDA, Rapid City, SD 57701 USA.

Over the past few decades, the frequency of wild pig-vehicle collisions(WPVCs) and number of human fatalities associated with these accidents have increased with expanding populations of this species, particularly in regions outside its native distribution. Aims. To better understand this widespread and growing human safety threat, we quantified habitat attributes associated with 311 WPVC locations occurring between 1983 and 2012 at the Savannah River Site (SRS) in South Carolina, USA, to test the hypothesis that WPVCs occur more frequently in areas proximal to preferred habitats (i.e. riparian and bottomland hardwood habitats). Methods. At each collision site, we measured the distance to the nearest wetland and stream, as well as the composition of habitats within 100-m and 1699-m buffers. We then contrasted habitat attributes associated with collision sites with those from randomly selected locations along the same roads, to identify habitat characteristics contributing to a higher incidence of these accidents. Key results. WPVCs were non-randomly distributed across both spatial scales measured, with collisions occurring more frequently in areas of preferred habitat for this species. Specifically, collisions occurred in areas closer to streams and containing less pine forest than at random locations at both spatial scales evaluated. Conclusions. Similar to vehicle accidents with other ungulate species, our study suggested that vehicle collisions involving wild pigs are spatially clustered around preferred habitat types. Management efforts to reduce vehicle collisions with wild pigs should be focussed in areas where roadways bisect preferred habitats such as stream crossings and bottomland hardwood or other riparian habitats. Implications. These data will aid in the development of mitigation strategies to reduce the frequency and impacts of WPVCs in areas of high wild-pig densities. However, given the paucity of data on WPVC mitigation, additional research is needed to quantify the efficacy of various methods (e. g. signage, fencing, underpasses) at reducing the frequency and severity of collisions with this species.

However, little is known about how fire may indirectly impact shrub performance by altering mycorrhizal symbionts. We used molecular tools, including ARISA and fungal ITS sequencing, to characterize the mycorrhizal communities on resprouting Betula nana shrubs across a fire-severity gradient after the largest tundra fire recorded in the Alaskan Arctic (July-October 2007). Fire effects on the components of fungal composition were dependant on the scale of taxonomic resolution. Variation in fungal community composition was correlated with fire severity. Fungal richness and relative abundance of dominant taxa declined with increased fire severity. Yet, in contrast to temperate and boreal regions with frequent wildfires, mycorrhizal fungi on resprouting shrubs in tundra were not strongly differentiated into fire-specialists and fire-sensitive fungi. Instead, dominant fungi, including taxa characteristic of late successional stages, were present regardless of fire severity. It is likely that the resprouting life history strategy of tundra shrubs confers resilience of dominant mycorrhizal fungi to fire disturbance by maintaining an inoculum source on the landscape after fire. Based on these results, we suggest that resprouting shrubs may facilitate post-fire vegetation regeneration and potentially the expansion of trees and shrubs under predicted scenarios of increased warming and fire disturbance in Arctic tundra.

A nondestructive inspection procedure was employed to evaluate the true condition of the heavy timbers that serve as the main framing structure of the building. The on-site investigation involved monitoring of the microclimate environment resulting from the paper machine operations, wood species identification, wood moisture content measurements, and internal decay detection using sounding, stress wave timing, and resistance micro-drilling methods. The testing results revealed that numerous locations were in poor condition indicated by widespread internal and external deterioration, reduced cross-sections from fire damages, and multiple failed members. Many timber members in the first floor exhibited a very high level of moisture condition (23 to 55%) as a result of high humidity air created by the paper making operations. This paper also showcases a new way of interpreting the evaluation results as straightforward as possible to the customer by creating 3D model-drawings and colored condition mappings.

Combining physics, chemistry and engineering, Ernest Lawrence invented the cyclotron, resulting in advancing nuclear physics, particle physics, molecular and materials science, and nuclear medicine. Using isotope- C-14, Melvin Calvin elucidated the photosynthesis cycle. Coupling photomultiplier tubes (PMTs) with NaI scintillation crystal, Hal Anger revolutionized nuclear imaging. Shashi Kumar and co-workers used biology and polymerase chain technology for the detection of mislabeled food materials. Combinations of biotechnology, chromatography, analytical chemistry and electron microscopy have resulted in organic chemists' improved ability to synthesize isoprene compounds of interest. These are some of the examples that have moved science forward and demonstrate that physical, chemical, biological, and biotechnological sciences are incomplete without each other. The single most important advance in the use of centrifugal force to separate biologically important substances was the coupling of mechanics, optics and mathematics, by T. Svedberg and J.W. Williams in the 1920's (http://humantouchofchemistry.com/theodorsvedberg.htm). The sedimentation coefficient is the rate at which particles of a given size and shape travel to the bottom of a tube under centrifugal force. The Svedberg unit is named after the Swedish chemist Theodor Svedberg (1884-1971), winner of the 1926 Nobel Prize in Chemistry for his work on colloids and his invention of the ultracentrifuge. Combining physics, chemistry and engineering Ernest Lawrence of the Lawrence Berkeley Laboratory invented Cyclotron (Fig 1). (http://www.nobelprize.org/nobel_prizes/physics/laureates/1939/lawrence-bio.html). The First Cyclotron, measuring only 5 inches in diameter, was constructed of glass, sealing wax and bronze; the material cost was about $25 (Fig 1). For his invention of the cyclotron, Lawrence was awarded the 1939 Nobel Prize in Physics. C1 ARS, Western Reg Res Ctr, USDA, Albany, CA 94710 USA.

We therefore tested VIGS in gladiolus (Gladiolus grandiflora L) using a Tobacco Rattle Virus (TRV) vector containing a fragment of the gladiolus gene encoding phytoene desaturase (PDS). Gladiolus corms and plants were infiltrated with cultures of Agrobacterium tumefasciens transformed with the vector system. We tested the effect of different inoculum concentrations, different inoculation strategies and different growing temperatures after inoculation. Successful gene silencing was obtained by syringe inoculation of the sprouted corms) with Agrobacterium at an OD600 of 2 using syringe infiltration of the young bud, and growing the plants at 18 degrees C after inoculation. White streaks characteristic of silencing PDS were first observed four weeks after inoculation and symptoms continued to develop up to eight weeks after inoculation. Silencing was not observed in plants grown at other temperatures, inoculated with lower concentrations of Agrobacterium, or inoculated by other means (corm, leaf, or vacuum infiltration). This is the first report on the potential use of TRV based VIGS in gladiolus and this optimised procedure of the TRV induced gene silencing should further facilitate for highly efficient functional analysis of genes.

Most effective programs release only males to avoid any crop damage caused by female fruit flies or transmission of disease by female mosquitoes. Therefore, the females have to be eliminated, preferably in an early developmental stage, during mass rearing. Different systems and techniques have been created for the sex separation of a few insect species. One of these is the transgenic sex-specific fluorescent protein marking of the insects with automated fluorescent-based sorting of the individuals to achieve sex separation. Here we describe the Y-linked integration of fluorescent markers driven by the widely active Drosophila melanogaster polyubiquitin promoter in the Caribfly, Anastrepha suspensa. Four strains with Y-linked integrations were established with one line expressing the DsRed fluorescent protein marker during embryogenesis. This line now has the possibility for use with automated sex separation in rearing, and the same transgene markers could be used in other insects for similar applications.

Many of these alternatives have shown promise, but limiting factors for integration and use of the alternatives substrate components continue to include: regional or national availability; transport costs; handling costs; lack of a uniform and consistent product; guidelines for preparation and use of materials or impact on current crop production practices. If a product can overcome the above limitations, then researchers are tasked with documenting substrate physical or chemical characteristics. The objective in all studies is to maintain or increase growth of nursery crops and to extend the longevity and acceptable physical properties for long-term woody ornamental crops. Proof of results is determined using laboratory analyses and crop growth studies. Physiochemical properties are monitored over days, weeks, and months to ensure stability. Particle size distribution and varying ratios of substrate components are manipulated to achieve optimal air filled porosity and available water content. Soilless substrates are amended with lime, sulfur and nutrients or blended with other substrate components to provide optimal chemical characteristics. Additionally, substrates are evaluated under industry conditions to determine impact on water, nutrient and pest management to better understand obstacles to commercial adoption. C1 [Bilderback, T.

Antagonistic yeasts of postharvest pathogens have been reported to induce several biochemical defense responses in host tissues of surface-wounded fruit. The interaction of yeast cells with fruit tissue resulted in major responses of the fruit that included enhanced production of ROS, phytoalexins, fungal cell wall degrading enzymes and the formation of structural barriers such as deposition of papillae and lignin in host cell walls. We have also shown that interaction of yeast cells with fruit tissue alters the volatile profile by down-regulation or up-regulation of certain compounds. To gain a better understanding of the molecular changes taking place in fruit tissue following the application of the yeast Metschnikowia fructicola, microarray analysis was performed on grapefruit surface wounds. The data indicated that 1007 putative unigenes showed significant expression changes following wounding and yeast application compared to wounded controls. Microarray results of select genes were validated by RT-qPCR. The data indicated that yeast application induced expression of Rbo, MAPK and MAPKK, G-proteins, CHI, PAL, CHS, 4CL. In contrast, three genes POD, SOD and CAT were down-regulated in grapefruit peel tissue treated with the yeast cells. Suppression was correlated with significantly higher levels of hydrogen peroxide, superoxide anion and hydroxyl radical production in yeast-treated surface wounds. This study provides the first global picture of gene expression changes in grapefruit in response to yeast antagonists.

An important goal of postharvest research is to reduce losses of fruits and vegetables after harvest. Postharvest losses have been a serious problem in every country of the world. The magnitude of postharvest losses varies in different regions depending on location, climate, commodity, and handling systems. The reduction of postharvest losses results in an increase of quantity available to consumers, thus increasing production without using more land. Therefore, reducing losses is crucial for food security in countries especially where land is scarce. The increased quantity available to consumers due to reduced losses is also made without any additional use of labor, fertilizers, water and other resources. This translates to more profit and wealth to farmers, as well as more preservation of natural resources and the environment. Another goal of postharvest research is to maintain quality of fresh produce after harvest. An increasingly important aspect of produce quality is its nutritional value. Consumption of fruits and vegetables has been linked to a reduction in the risk of cardiovascular disease, cancer, diabetes, and age-related disorders. In addition to vitamins, minerals and other nutrients, fruits and vegetables are a source of many phytochemicals, which are responsible for health protection and disease prevention. Significant increases in the concentration of phytochemicals and nutritional quality of fruits and vegetables are certainly achievable through proper postharvest handling. Several postharvest techniques have been demonstrated to not only maintain but also enhance levels of flavonoids, carotenoids and other antioxidants. Postharvest research, thus, is important for improving our wealth and health. C1 ARS, Beltsville Agr Res Ctr, USDA, Beltsville, MD 20705 USA.

A total of 28 cold hardy and non-cold hardy Camellia genotypes were evaluated using 11 EST-PCR and 60 RAPD primers. One EST-PCR primer pair based on a Camellia sinensis sequence (here referred to as CAME 13; forward, 5'-CGGGCAGGTACCTTCTGATA-3' and reverse, 5'-TGCAGAAGATGGAGATGCAG -3') and one RAPD primer (Operon A-12) appeared to have potential for discriminating between the cold hardy and non-cold hardy genotypes. SCAR primer pairs were designed based on the sequence of the C. japonica bands amplified by the CAME 13 and Operon A-12 primers. The ESTSCAR-19839 primer pair (forward, 5'-CGGGCAGGTACCTTCTGATA-3'; reverse, 5'-CCTCAGCCGTAGTTGCATTT-3') proved useful for identifying noncold hardy Camellia plants, whereas the fragment amplified by the RAPD-based SCAR primers appeared monomorphic.

The success of new crops programs in Denmark and the Netherlands can be attributed to continuous efforts to identify candidate new species and develop market-orientated year-round production systems. Growers often produce a single crop or several crops in highly mechanized greenhouses or outdoors where environments are suitable. Many genera from around the world with potential for potted plant production were evaluated in collaboration with a "New Crops Advisory Committee" representing major industry members in the US and abroad at the ARS' Floral and Nursery Plants Research Unit in Beltsville, MD. Cultural information on the production of new crops such as Eustoma, Clematis, Gerbera, and Anigozanthos was released to the industry through trade magazines and many scientific papers on dwarf Eustoma, Lachenalia, Correa, and Ornithogalum describing on the growth and flowering we also published. The purpose of this review is to summarize observations and conclusions on the process of new crop development based on the research results and to describe the factors, such as aesthetic value, crop production technology, growth and flowering physiology, and marketing required for success. This information is essential for the development of new floral crops for domestic and international markets. C1 ARS, USDA, Floral & Nursery Plants Res Unit, Beltsville, MD 20705 USA.

Bulb scale and basal meristem explants were inoculated with A. tumefaciens strain AGL1 containing the binary vector pCAMBIA 2301 which has the uidA gene that codes for beta-glucuronidase, GUS expression. Transformed bulb scales showed transient GUS expression when they had been precultured 11 days on Murashige and Skoog's (MS) medium supplemented with 2 mg/L dicamba. The outer, larger-sized bulb scales were not infected nearly as well as the inner, smaller bulb scales. Maximum GUS expression occurred when bulb scales had been obtained from plants that had been grown in the dark for at least 2 months rather than in the light indicating the importance of growing plants in the dark for Agrobacterium-mediated transient transformation of bulb scales. Basal meristems taken from plants grown 4 months in the dark showed 3 times as much GUS expression as basal meristems from plants grown in a 12 h light photoperiod. The frequency of transient GUS expression achieved in this study indicated that it should be possible to achieve stable transformation of 'Nellie White' which is the cultivar that dominates the US market of Easter lilies. Experiments for stable transformation are in progress. C1 [Ozel, C. A.] Gazi Univ, Fac Educ, Ankara, Turkey.

TI Estimation of surface water quality in a Yazoo River tributary using the duration curve and recurrence interval approach SO WATER SCIENCE AND TECHNOLOGY-WATER SUPPLY LA English DT Article DE dissolved oxygen; load duration curve; recurrence period; specific conductivity; water quality ID LOAD AB Pollution of surface water with harmful chemicals and eutrophication of rivers and lakes with excess nutrients are serious environmental concerns. This study estimated surface water quality in a stream within the Yazoo River Basin (YRB), Mississippi, USA, using the duration curve and recurrence interval analysis techniques. Data from the US Geological Survey (USGS) surface water monitoring station located in Deer Creek east of Leland from the YRB were selected for the analysis. Results showed that the water quality constituents, namely water temperature, specific conductivity (SC) and dissolved oxygen (DO), in this stream were found not to be the major concerns as the percentages of the time when these constituents did not meet their criteria were very low. Our results further revealed that the water temperature and SC increased as time elapsed, indicating the potential global warming and contamination impacts in this stream. In contrast, the DO and pH decreased as time elapsed, postulating a potential increase in biochemical oxygen demand and an acidic trend in this stream. Over the last decade, the average recurrence intervals when the water temperature, SC, and DO did not meet their criteria or minimum conditions were around 1 year. Using a target DO value of 429 kg d(-1) proposed by the Mississippi Department of Environmental Quality, results from this study showed that there was about 25% of the time when the DO load did not meet the target value. This study suggests that the duration curve and recurrence interval analysis techniques are useful statistical tools for water quality trend estimation.

The data have been recorded from human subjects while they were staying in whole room calorimeter chamber for 48 hours. This allowed very accurate measurements of their oxygen consumption, energy expenditure and substrate oxidation. These physiological parameters are notorious for their inaccuracy when measured in field conditions. The subjects wore two types of body sensors: the Hidalgo Equivital (TM) (Cambridge, UK) physiological monitors with a telemetry thermometer pill and iPro Professional Continuous Glucose Monitoring System (CGMS) (Medtronic MiniMed, Inc, Northridge, CA). The data collected by these two systems and by the calorimeter chamber were subsequently analyzed off-line using the functional regression techniques. The energy expenditure, substrate oxidation, and body core temperature were used as response variables, while heart rate, respiratory rate, subcutaneous glucose concentration, and skin temperature were used as predictors. The results show that the 24-hours and instantaneous energy expenditure values can be inferred from instantaneous measurements of heart rate, respiratory rate and glucose concentrations. Also, the body core temperature can be inferred from heart rate, respiratory rate, glucose concentration, and skin temperature. The substrate oxidation was the most difficult parameter to infer and it can only be accomplished during the exercise activity.

S. Department of Agriculture (USDA) Agricultural Research Service (ARS) National Plant Germplasm System (NPGS) has preserved clonal plant genetic resources of horticultural crops in field gene banks. Facilities in Hilo, Hawaii; Mayaguez, Puerto Rico; Miami, Florida; and Riverside, California, were established to preserve tropical and subtropical fruit and nut crops; facilities in Brownwood, Texas; Corvallis, Oregon; Davis and Parlier, California; and Geneva, New York, preserve the temperate crops. Each of these facilities now has internationally recognized globally diverse collections for assigned genera. These 9 gene bank locations maintain >34,000 accessions representing >2,700 taxa of fruit and nut crops and their wild relatives. Germplasm of unique clonal genotypes are maintained as living specimens. Seed lots represent native populations for crop wild relatives. Remote backup plants are secured through tissue culture or cryogenic storage of the clones at the USDA ARS National Center for Genetic Resource Preservation in Ft. Collins, Colorado. The genetic resources are characterized and evaluated for phenotypic and genotypic traits that are documented in the USDA-ARS Germplasm Resources Information Network (GRIN) database. Phytosanitary certification is obtained to meet quarantine regulations of the import permit prior to distribution. Samples of more than 15,000 accessions are shipped annually to international researchers. While originally conceived as working collections for crop improvement, these US genebanks have become invaluable in providing the raw materials for basic plant genetic research, reservoirs for rare or endangered species or vulnerable landraces, archives of historic cultivars, and field classrooms for education. Leaves and other samples from these collections are frequently requested for molecular markers and DNA analysis. These collections preserve botanical treasures as well as the American horticultural heritage for now and for future generations.

As part of this mission, USDA-ARS develops new means of breeding to increase selection efficiency in breeding new hop varieties. Conventional quantitative genetic studies were pursued from 1996-2004 while molecular approaches have been more recent. These molecular approaches have been used to quantify genetic diversity between male and female accessions, identifying superior parents and superior mating pairs and more recently to identify molecular markers to be used in selection. Most recently, the USDA-ARS along with researchers from several other countries, are pursuing the sequencing of the complete hop genome with hopes of identifying regions controlling important traits in hop production. These studies involve next generation sequencing coupled with modern biometrics to assemble and align the hop genome. C1 USDA ARS NFSPRC, Corvallis, OR 97331 USA.

The system houses more than 500,000 accessions comprising over 2100 genera and more than 13,100 species. The NPGS has collections for about 85 major crops. It is one of the world's largest collectors and distributors of germplasm. This public germplasm management system has yielded large economic benefits to public and private organizations worldwide. Plant genetic resources (PGRs) serve as the basic materials for research and development to sustain agricultural productivity. They provide useful characteristics and genes for food, feed, fiber, ornamental, and energy uses. Endangered globally by human and natural forces, their conservation is essential to the wealth and future of mankind. The NPGS research programs are dedicated to answering questions that help curators and researchers conserve and manage genetic resources in a more effective and cost-efficient manner. Characterization and evaluation information is collected by curators, staff and researchers on agronomic performance, biochemical, genetic, phenotypic traits and qualities. Digital images are captured to provide useful detail on plant, fruit and seed structures, and permanent information for reference use. Analysis of highly heritable traits supports taxonomic identification and quality assurance. Information on their adaptation, maturity, and reactions to environmental or physical stress is valuable to researchers. This paper examines PGRs held at three clonal repositories for tropical/subtropical fruit crops. These are the Subtropical Horticultural Research Station (SHRS) in Miami, FL, the Tropical Agriculture Research Station (TARS) in Mayaguez, PR, and the Tropical Plant Genetic Resource Management Unit (TPGRMU) in Hilo, HI.

(USA) and at elevations from 0-2,000 m. However, successful production of ripe dates is possible only in arid regions of Peru, Chile, Baja California, and south-west USA. At present, the major extant date palm groves of Spanish origin are in Baja California, Mexico and Peru. A study of the origin of the date palms has revealed abundant historical documentation permitting a historical picture of the Spanish introductions to the Americas and the origin of the plant material involved. Dates arrived in the Americas very soon after initial European contact (1492), and in the early 16th century there were date palms in the Caribbean Islands and on the mainland, as evidenced by the chroniclers of the Indies. Date palm plantings were from seeds carried from Spain and North Africa. By about the late 16th century, date palms reached coastal Peru. Date palms were recorded in present-day Baja California, Mexico and California USA from the mid-18th century. Cultivation has continued in Baja California in oases near former Spanish religious missions. Beginning in the late 19th century, date palm offshoots were imported from North Africa and the Middle East and today form the basis of the USA date industry. C1 [Johnson, D.

The Organic Research Network Project, funded by USDA-Organic Agriculture Research and Extension Initiative (USDA-OREI) program in 2004 (S.R. Gliessman, P.I.), was designed to 1) strengthen an existing organic research and extension network to support organic vegetable and strawberry producers in the region; and 2) develop integrated fertility and pest management strategies in order to minimize negative impacts of agriculture on surrounding natural ecosystems and improve the economic viability of organic farming. The project participants included multidisciplinary researchers, extension personnel, organic growers, a land owner, and three NGOs. Ten studies on fertility management, soil-borne disease management, arthropod pest management, weed management, and economic analysis in organic strawberry and vegetable production were conducted. Three core growers played a crucial role in designing, implementing, and evaluating on-farm trials. To evaluate the impact of the project, we conducted pre- and post-project assessments. At the end of the project, 15 of the 18 participants said it had met or exceeded their expectations and the remaining 3 said that most of their expectations were met. Participants were motivated by a desire to build community, increase opportunities to collaborate, improve linkages between farmers and researchers, and improve access to and exchange of information. Participating growers appreciated the many opportunities for interaction with researchers, felt the project provided useful information, and reported that it had either reinforced or changed practices used on their farms. Extension personnel commented on the successful collaborations, improved knowledge of organic production, and the impact it had on growers in the area. This project contributed to the "Organic Strawberry Production Manual" (Koike et al., 2012). The Organic Research Network is further expanding with new funding from the USDA-OREI program in 2011 (C.

Our initial approach was to evaluate the possible benefits of adding a bait composed of brown sugar and compressed bread yeast, Saccharomyces cerevisiae. A direct comparison of the sugar-yeast bait with the protein-based baits, GF-120 (R) and Nu-Lure (R), in laboratory tests showed that it was more effective than either commercial product. We found that fly mortality at 2 and 6 h significantly increased throughout the season with the addition of the sugar-yeast bait. In particular, the addition of the sugar-yeast bait to Entrust increased fly mortality 4-fold in early-season bioassays with green and yellow cherries. While the mean numbers of eggs laid and larval infestations of cherry was reduced (50%) with the addition of the sugar-yeast bait, these differences were not significant. Studies are continuing in 2012 with a new yeast candidate that is an effective biofungicide combined with a higher concentration of sugar that may be an effective repellent of birds. The potential of this bait to improve control of the western cherry fruit fly, Rhagoletis indifferens is also being evaluated.

Phacidiopycnis rot can originate from infection of wounds on the fruit. In this study, two biocontrol agents, BioSave (a Pseudomonas syringae strain) and Cryptococcus laurentii strain 87-108, were compared with the conventional fungicide thiabendazole (TBZ) for their efficacy in controlling Phacidiopycnis rot. 'D'Anjou' pear fruit were surface disinfected, wounded with a finishing nail head, treated with one of the biocontrol agents or TBZ, and inoculated with conidial suspension of P. piri. An untreated control where fruit were inoculated with the pathogen was also included in the trial. The experiment was conducted twice using fruit from different orchards where no fungicides were used. Each treatment contained four 20-fruit replicates. Inoculated fruit were placed on fiber fruit trays wrapped with perforated bags and stored in cardboard boxes at 0 degrees C for three months, at which time decay was assessed. Over 92% of the fruit in the untreated control developed Phacidiopycnis rot. BioSave and C. laurentii significantly reduced incidence of Phacidiopycnis rot by 96-98 and 38-45%, respectively, compared with the control. BioSave was more effective than C. laurentii. No decay was observed on TBZ treated fruit, but there was no statistical difference in decay incidence between BioSave and TBZ treatments. The results suggest that BioSave is effective in controlling Phacidiopycnis rot originating from wound infections by P. piri and can provide a level of control of Phacidiopycnis rot comparable with that of TBZ.

The demand for alternatives to synthetic fungicides is much greater than the supply provided by these new technologies, including biological control. The development of a postharvest disease biocontrol product is a lengthy process involving many steps. The need for alternatives to synthetic fungicides and opportunities for biological control under controlled environmental conditions in storage have been the driving forces for research in this area. Research around the world has proven the effectiveness of biological control of postharvest diseases and, at the same time, identified its limitations. Many of these limitations result from knowledge gaps that can be addressed by additional research to better understand the mechanisms of biocontrol on fruit, microbial ecology of the fruit surfaces, and the survival of antagonists under adverse conditions. Additional research is also needed to prolong the shelf life of antagonists, determine the compatibility of biocontrol with other alternative treatments, and adapt biocontrol to various postharvest handling practices, and to new production technologies, such as mechanical harvesting, that may predispose fruit to decay. The greater use of biological control of postharvest diseases can be achieved by expanding the application of available products to new commodities and different pathogens. The products currently available were developed to control decays originating from wound infections; however, significant postharvest losses on various fruits may also occur from decays originating from latent infections that develop before harvest. Controlling these decays has become the new frontier for biological control. New approaches utilizing natural fruit wax and artificial membranes were developed to find antagonists effective in controlling latent infections under laboratory conditions. The high cost of tests required for registration prohibited the commercial development of several effective biocontrol agents. A new framework is needed for streamlining the registration of low risk biocontrol agents without known deleterious effects to human health. This is especially relevant for those agents that are consumed with foods in large quantities (e.g., in apple cider, fruit juices, or with various cultured food products (probiotics)). Biological control of postharvest diseases has been accepted by the fruit industry as a viable alternative to synthetic fungicides, and products registered in the United States can be used on organically-labeled fruit.

The disorder develops during cold storage and intensifies after removal to market temperatures. Scald symptoms result from necrosis of a few hypodermal cell layers and manifest as brown or black patches on the fruit skin. Susceptibility to scald varies greatly by cultivar, and is also influenced by preharvest factors such as growing climate and maturity, and postharvest factors including storage atmosphere, ventilation, and temperature. Despite many years of investigation, the biochemical mechanisms underlying scald are still in question. The disorder is thought to be a type of chilling injury induced by oxidative stress. A long-standing hypothesis holds that oxidation products of the sesquiterpene alpha-farnesene are directly involved via generation of free radicals. Variation in the antioxidant defense mechanisms required to scavenge radicals and combat oxidative stress is postulated to also play a key role in susceptibility or resistance to scald. A marked rise in alpha-farnesene synthesis typically occurs shortly after scald-susceptible fruit are placed in storage and oxidation of the alpha-farnesene to conjugated trienols (CTols) proceeds rapidly after about 6-8 weeks, particularly in air storage. High level accumulation of CTols during storage is usually correlated with the incidence and severity of scald. Further evidence supporting a link between alpha-farnesene oxidation and induction of scald was the finding that prestorage treatment of apples or pears with 1-methylcyclopropene (1-MCP), a blocker of ethylene action, drastically reduced alpha-farnesene synthesis and scald development. Silencing genes that control alpha-farnesene biosynthesis or conversion to CTols should prove or disprove a major role of alpha-farnesene oxidation in the induction of scald. The primary target for gene knockout is AFS1 encoding a-farnesene synthase, which catalyzes the final step in a-farnesene biosynthesis. Enzymatic production of CTols is as yet hypothetical, but possibly a glutathione peroxidase or glutathione S-transferase catalyzes reduction of farnesyl hydroperoxides to the corresponding alcohols. In addition, the precise mechanisms whereby 1-MCP, diphenylamine, UV-visible light irradiation, initial low oxygen stress, and intermittent warming ameliorate or prevent scald are currently being investigated using biochemical, functional genomics, and metabolomics approaches.

The study was laid out in a randomized complete block design with four levels of nitrogen fertilizer as treatments: control (000N), 112 (112N), 224 (224N), and 336 (336N) kg/ha of nitrogen, with each treatment replicated in 4 blocks. Two trees were destructively sampled from each plot giving a total of 32 trees. Bolts 0.6 m in length were collected from each tree (3 bolts per tree); with the midpoint of each bolt at heights of 2.4, 7.3 and 12.2 m from the base of the tree (each bolt represented the midpoint of standard 4.9 m saw logs). Static bending samples with dimensions 25 by 25 by 406 mm (radial, tangential and longitudinal dimensions respectively) were cut from the bolts that included the 25 mm of wood produced immediately following fertilization. Data on modulus of elasticity (MOE, stiffness) and modulus of rupture (MOR, strength) were collected from clear static bending samples. Based on the analysis of variance, no significant treatment effect was observed on MOE and MOR. However, MOE and MOR decreased in wood produced immediately after fertilization for trees which received the highest level of fertilization (336N). A decreasing trend in MOE and MOR with height was also present. C1 [Antony, Finto; Daniels, Richard F.] Univ Georgia, Warnell Sch Forestry & Nat Resources, Athens, GA 30602 USA.

In this context, the term hydraulic architecture takes on a broader meaning, making it essential to understand how static and, above all, dynamic hydraulic properties are integrated at the organismal level. Here we discuss some key processes operating in roots, stems and leaves that act in a coordinated manner to stabilize plant hydraulic function under both non-extreme and extreme conditions such as prolonged drought. Hydraulic redistribution (HR) is often manifested as reverse flow of water in shallow roots via transport of water from deeper soil layers. By partially uncoupling root water potential from that of the surrounding dry soil and slowing the rate of soil drying, HR serves to mitigate seasonal drought-induced hydraulic dysfunction in roots and to maintain nutrient uptake, thereby extending their lifespan. Stems of many species show a high capacity for refilling of embolized xylem conduits. This is an important component of their apparent hydraulic safety margins that is likely to be related to xylem structural features that confer resistance to tension-induced embolism. Hydraulic capacitance in stems contributes to hydraulic safety margins by dampening fluctuations in xylem tension that might otherwise result in excessive embolism. Embolism-induced loss of stem xylem conductivity can be partially compensated by rapid increases in the ionic concentration of xylem sap in remaining functional conduits. In many species, leaves lose and recover a substantial fraction of their hydraulic conductance daily, suggestive of a hydraulic circuit breaker function that promotes stomatal closure to avoid excessive embolism in stems upstream. The functioning of these homeostatic processes is likely to be influenced by the drier climates that are predicted for much of the globe. C1 [Meinzer, F. C.; Woodruff, D.

Seed propagation is important for the introduction of new genotypes ( accessions), especially crop wild relatives. Additionally, seed may be produced by breeding or to otherwise support research. Temperate tree fruit and nut crop seeds typically exhibit dormancy, which must be overcome to produce seedlings. Clonal genebanks generally acquire new clones as vegetative material that must be propagated. Additionally, perennials, such as tree fruit and nut crops have limited productive lives and therefore must be replaced in a timely manner. This requires clonal propagation methods, such as rooting cuttings, grafting and budding, layering, or micropropagation. There are excellent opportunities to conduct propagation and other research on the collections at clonal genebanks. This enriches a collection especially when the research results are made freely available at public websites. Those receiving requested material will have critical propagation information as a result of this research. Ease of propagation greatly increases the utility of the plant material in a collection.

Although a variety of factors, including satiation of aboveground predators and avoidance of interbrood hybridization, have been hypothesized to shape the evolution of this system, no empirical support for these mechanisms has previously been reported, beyond the observation that bird predation can extirpate small, experimentally mistimed emergences. Here we show that periodical cicada emergences appear to set populations of potential avian predators on numerical trajectories that result in significantly lower potential predation pressure during the subsequent emergence. This result provides new support for the importance of predators in shaping periodical cicada life history, offers an ecological rationale for why emergences are synchronized at the observed multiyear intervals, and may explain some of the developmental plasticity observed in these unique insects.

We radio tracked 13 pregnant and 12 lactating Myotis sodalis (Indiana bat) during the maternity season in northern Missouri. Mean (+/- SE) home range area for all individuals based on the fixed kernel method for the 50% and 95% probability contours was 204.52 28.87 ha and 1137.13 +/- 144.06 ha, respectively. Home range size did not differ significantly (P> 0.16) between pregnant and lactating females. However, the mean home range area based on the 95% probability contour for lactating individuals (1361.00 +/- 267.16 ha) was 32% larger than the area used by pregnant individuals (930.47 +/- 109.59). The mean maximum distance pregnant and lactating individuals were located from the roost was 3.75 km (range: 1.89-5.13 lcm) and 4.85 km (range: 2.17-9.40 km), respectively. Home range size and maximum distance traveled during the maternity season were greater than previously reported for M. sodalis. Our sample size is modest due to the rarity and patchy distribution of this endangered species, but we provide meaningful information on spatial area used to acquire necessary resources during the maternity season.

This study was carried out to determine the reaction of Scots pine (Pinus sylvestris L.) trees to mechanical bark stripping that imitates the damage to tree stems caused by moose (A ices alces L.). There was a significant difference between the height increment of control and damaged trees during first year after treatment. However, damaged trees quickly recovered and resumed growth. The differences among damage treatments (removing 30, 60, and 90% bark) were not significant. Tree size affects tree growth, which means that the growth reduction after bark stripping will be compounded over future tree growth and may determine the competition interrelations C1 [Metslaid, Marek; Koester, Kajar; Jogiste, Kalev; Randveer, Tiit; Voolma, Kaljo] Estonian Univ Life Sci, Inst Forestry & Rural Engn, EE-51014 Tartu, Estonia.

For convenience, these research activities can be grouped into 8 themes: 1) greener catalysis, 2) diverse feedstock base, 3) degradable polymers and waste minimization, 4) recycling of polymer products and catalysts, 5) energy generation or minimization during use, 6) optimal molecular design and activity, 7) benign solvents, and 8) improved syntheses or processes in order to achieve atom economy, reaction efficiency, and reduced toxicity. All these areas have attracted worldwide attention, with contributions variously from academic, industrial, and government laboratories. Many new promising technologies are being developed. Whereas most aspects of green polymer chemistry are covered in this review, special attention has been paid to biocatalysis and biobased materials due to the specific research interests of the authors. Appropriate examples are provided, taken particularly from the articles included in this symposium volume. C1 [Cheng, H. N.] ARS, So Reg Res Ctr, USDA, New Orleans, LA 70124 USA.

Common beans (Phaseolus vulgaris L.) are well known, widely available, and relatively cheap. They contain polysaccharides, proteins, triglyceride oils, minerals, vitamins, and phenolic antioxidants. Many of these compounds seem to be attractive components for food and biobased products. A review is given here of the more promising approaches for these applications, emphasizing in particular the work done by the authors in the past several years. These include 1) extrusion cooking of whole beans as food products, 2) use of beans as fillers in polymeric blends and composites, 3) extraction of triglyceride oils from whole beans, 4) extraction of phenolic phytochemicals from beans, and 5) conversion of starch in beans to ethanol. These examples illustrate the range of applications possible and the potential value of non-conventional uses of common beans.

Isolate yield was 2.5-fold greater from the glandless meal than from the glanded meal, indicating that the gossypol in the glanded meal was likely promoting the formation of protein aggregates that were more difficult to extract. Both isolate preparations were very high in protein (>96%). Electrophoresis showed essentially identical band patterns in the meals and isolates, although some bands appeared to be preferentially concentrated in the isolates. Small shifts in the amino acid distributions were apparent the most notable being a decrease in the lysine and an increase in the arginine levels in the isolates compared with the meals. Cottonseed isolates demonstrated considerable solubility in both acidic and alkaline environments. Functional properties were largely within the range of typical values for protein preparations. The composition and functional properties of the glandless isolates suggest that cottonseed proteins should be useful in food formulation.

Although most of the attention has been paid to soybean oil thus far, cottonseed oil is a viable alternative. An advantage of cottonseed oil is that the reactive groups consist primarily of oleic and linoleic moieties, and their amounts can be varied with appropriate hydrogenation. In this work a detailed hydrogenation study is carried out using three commercially available Ni, Pt and Pd catalysts under different hydrogenation conditions. Kinetic modeling of the observed data has also been done. With cottonseed oil and selective use of hydrogenation, oleic acid content up to 40% and linoleic acid content up to 53% can be produced, and these functionalities can be derivatized to produce specific biobased products. In addition, relative to the hydrogenated soybean oil, hydrogenated cottonseed oil exhibits lower trans fatty acid, and this feature may be beneficial in the context of food use. C1 [Cheng, H.

In this work we examined the mechanical properties of composites of low density polyethylene (LDPE) and cotton burr. The burr was ground into powder and separated by size into several fractions. These were separately blended with the polymer and then injection molded. Four compatibilizing polymers (polyethylene-g-maleic anhydride, polyethylene-co-methacrylic acid, and polyethylene-co-acrylic acid at two acrylic acid levels) were included to observe their effects on the mechanical properties. In general, the addition of these fillers to LDPE reduced tensile strength and elongation, but enhanced Young's modulus. Improvement in tensile strength was observed for samples containing two of the tested compatibilizers. The results suggested that LDPE-cotton burr-compatibilizer composites may be useful in applications where reduced cost is desirable and reductions in mechanical properties are acceptable.

We review the environmental factors controlling their structure and global distribution and evaluate their current and future trajectory. Adaptations of trees to climate and resource gradients, coupled with disturbances and forest dynamics, create complex geographical patterns in forest assemblages and structures. These patterns are increasingly discernible through new satellite and airborne observation systems, improved forest inventories, and global ecosystem models. Forest biomass is a complex property affected by forest distribution, structure, and ecological processes. Since at least 1990, biomass density has consistently increased in global established forests, despite increasing mortality in some regions, suggesting that a global driver such as elevated CO2 may be enhancing biomass gains. Global forests have also apparently become more dynamic. Advanced information about the structure, distribution, and biomass of the world's forests provides critical ecological insights and opportunities for sustainable forest management and enhancing forest conservation and ecosystem services.

Proteins were extracted from roots of 3 and 8 days post-inoculation (dpi) by soybean cyst nematode Heterodera glycines and separated by 2-DE. A difference in abundance was found in a total of 42 protein spots between the susceptible and resistance responses. After in-gel digestion with trypsin, 39 spots representing 33 proteins were subsequently identified by LC-MS/MS. The proteins showing 1.5-fold changes in intensities are related to biochemical processes that may be differentially altered after soybean cyst nematode challenge. The identified proteins belong to the categories of metabolism, energy, cell growth and division, transcription, protein synthesis, protein destination and storage, signal transduction, disease/defense, and secondary metabolism. Taken together, our study provides important information on the use of proteomic methods for studying protein regulation during soybean-soybean cyst nematode interactions.

TI Parallel analysis of RNA ends enhances global investigation of microRNAs and target RNAs of Brachypodium distachyon SO GENOME BIOLOGY LA English DT Article ID TRANS-ACTING SIRNAS; ARABIDOPSIS-THALIANA; PLANT MICRORNAS; MIRNA TARGETS; TRANSLATIONAL INHIBITION; PHOSPHATE HOMEOSTASIS; TRANSCRIPTION FACTORS; REGULATORY NETWORKS; SPLINTED LIGATION; MESSENGER-RNAS AB Background: The wild grass Brachypodium distachyon has emerged as a model system for temperate grasses and biofuel plants. However, the global analysis of miRNAs, molecules known to be key for eukaryotic gene regulation, has been limited in B. distachyon to studies examining a few samples or that rely on computational predictions. Similarly an in-depth global analysis of miRNA-mediated target cleavage using parallel analysis of RNA ends (PARE) data is lacking in B. distachyon. Results: B. distachyon small RNAs were cloned and deeply sequenced from 17 libraries that represent different tissues and stresses. Using a computational pipeline, we identified 116 miRNAs including not only conserved miRNAs that have not been reported in B. distachyon, but also non-conserved miRNAs that were not found in other plants. To investigate miRNA-mediated cleavage function, four PARE libraries were constructed from key tissues and sequenced to a total depth of approximately 70 million sequences. The roughly 5 million distinct genome-matched sequences that resulted represent an extensive dataset for analyzing small RNA-guided cleavage events. Analysis of the PARE and miRNA data provided experimental evidence for miRNA-mediated cleavage of 264 sites in predicted miRNA targets. In addition, PARE analysis revealed that differentially expressed miRNAs in the same family guide specific target RNA cleavage in a correspondingly tissue-preferential manner. Conclusions: B. distachyon miRNAs and target RNAs were experimentally identified and analyzed. Knowledge gained from this study should provide insights into the roles of miRNAs and the regulation of their targets in B. distachyon and related plants.

However, influenza in pigs is a zoonotic viral disease well-known to virologists for almost one century with the classical H1N1 subtype the only responsible agent for swine influenza in the United States for many decades. Swine influenza was first recognized clinically in pigs in the Midwestern U. S. in 1918 and since that time it has remained important to the swine industry throughout the world. Since 1998, however, the epidemiology of swine influenza changed dramatically. A number of emerging subtypes and genotypes have become established in the U. S. swine population. The ability of multiple influenza virus lineages to infect pigs is associated with the emergence of reassortant viruses with new genomic arrangements, and the introduction of the 2009 pandemic H1N1 from humans to swine represents a well-known example. The recent epidemiological data regarding the current state of influenza A virus subtypes circulating in the Canadian and American swine population is discussed in this review.

TI SENSITIVITY AND FIRST-ORDER/MONTE CARLO UNCERTAINTY ANALYSIS OF THE WEPP HILLSLOPE EROSION MODEL SO TRANSACTIONS OF THE ASABE LA English DT Article DE Erosion modeling; First-order error analysis (FOEA); Monte Carlo simulation; Sensitivity analysis; Soil erosion; Uncertainty analysis; WEPP model ID SOIL-LOSS-EQUATION; NONPOINT-SOURCE POLLUTION; WATER-QUALITY MODELS; RANGELAND APPLICATIONS; GLUE METHODOLOGY; ERROR ANALYSIS; PREDICTIONS; EQUIFINALITY; CALIBRATION; VALIDATION AB Performing a comprehensive sensitivity/uncertainty analysis is a valuable step in understanding and using a predictive hydrologic/water quality (H/WQ) model. This article applies one-factor-at-a-time (OAT) sensitivity analysis (SA) and first-order error analysis (FOEA)/Monte Carlo simulation with Latin hypercube sampling (LHS) uncertainty analysis techniques for evaluation of a complex, process-based water erosion prediction tool, the USDA Water Erosion Prediction Project (WEPP) model (version 2010.1). Assessment of the WEPP hillslope profile model on a Midwestern U. S. Miami silt loam soil for three cropping/management scenarios and three erosion process cases (as defined by topography) is described. WEPP model runoff, soil loss, and corn (Zea mays L.) yield output responses in the form of expected values and error variances were determined to illustrate model prediction uncertainty. The OAT SA showed that WEPP runoff and soil loss output responses were most sensitive to changes in the baseline effective hydraulic conductivity (K-b) and sand content. WEPP model corn yield output response was most sensitive to crop input parameters affecting the simulation of biomass development. The FOEA showed that the largest contributions to runoff, soil loss, and corn yield total error variance came from K-b and sand/clay content, K-b and baseline soil erodibility factors, and the biomass energy ratio of a crop and harvest index, respectively. The FOEA total variances presented in this study for runoff and soil loss were considerably larger than the corresponding Monte Carlo LHS simulation total variances. The Monte Carlo LHS total variance results were reasonable, making Monte Carlo LHS appear to be a better alternative for quantifying WEPP output response error variance. The Monte Carlo LHS soil loss output responses were also compared to Universal Soil Loss Equation (USLE) soil loss predictions. The USLE soil loss estimates were within the Monte Carlo LHS 90% prediction intervals for six of the nine cropping/management and erosion process cases. Results of this study illustrate the usefulness of combining SA and Monte Carlo LHS for providing detailed uncertainty analysis information for complex, physically based models such as WEPP.

TI ADVANCES IN SOIL EROSION RESEARCH: PROCESSES, MEASUREMENT, AND MODELING SO TRANSACTIONS OF THE ASABE LA English DT Article DE Experimentation; Modeling; Research; Soil erosion ID WATER AB Soil erosion by the environmental agents of water and wind is a continuing global menace that threatens the agricultural base that sustains our civilization. For over 70 years, ASABE members have been at the forefront of research to understand erosion processes, measure erosion and related processes, and model very complex sediment detachment, transport, and deposition. The ASABE Erosion Control Group (SW-22) and Erosion Control Research (SW-223) committees periodically sponsor international symposia to provide an avenue for exchange of ideas and information by engineers, scientists, and students from around the world. The two most recent symposia were the Soil Erosion Research for the 21st Century Symposium held in January 2001 in Honolulu, Hawaii, and the International Symposium on Erosion and Landscape Evolution (ISELE) held in September 2011 in Anchorage, Alaska. This article describes these two events, provides a description of major outcomes, and introduces a collection of papers that were presented as part of the 2011 ISELE in Alaska. The ISELE sessions focused on seven themes: water erosion process research; aeolian erosion and fugitive dust emission; highly disturbed, urban, and arid lands; erosion measurement and assessment; prevention and control of upland and in-stream erosion; soil erosion modeling; and impacts of global change on erosion and landscape evolution. More than 120 people from 16 countries attended the ISELE and gave 112 oral and poster presentations. From those presentations, 24 papers were accepted for publication in Transactions of the ASABE (22 papers, this issue) and Applied Engineering in Agriculture (two papers, next issue). The results from these symposia and in these papers show active and vibrant research to address soil erosion problems, particularly in the face of global environmental changes. C1 [Flanagan, D.

TI INTERNAL EROSION DURING SOIL PIPEFLOW: STATE OF THE SCIENCE FOR EXPERIMENTAL AND NUMERICAL ANALYSIS SO TRANSACTIONS OF THE ASABE LA English DT Article DE Ephemeral gully erosion; Erodibility; Internal erosion; Landslides; Pipeflow; Soil pipes ID LATERAL PREFERENTIAL FLOW; EPHEMERAL GULLY EROSION; PIPING SAPPING EROSION; SEEPAGE EROSION; HYDRAULIC-PROPERTIES; SLOPE STABILITY; SUBSURFACE FLOW; WATER DYNAMICS; SWIRLING FLOW; MASS-TRANSFER AB Many field observations have led to speculation on the role of piping in embankment failures, landslides, and gully erosion. However, there has not been a consensus on the subsurface flow and erosion processes involved, and inconsistent use of terms have exacerbated the problem. One such piping process that has been the focus in numerous field observations, but with very limited mechanistic experimental work, is flow through a discrete macropore or soil pipe. Questions exist as to the conditions under which preferential flow through soil pipes results in internal erosion, stabilizes hillslopes by acting as drains, destabilizes hillslopes via pore-pressure buildups, and results in gully formation or reformation of filled-in ephemeral gullies. The objectives of this article are to review discrepancies in terminology in order to represent the piping processes better, to highlight past experimental work on the specific processes of soil pipeflow and internal erosion, and to assess the state-of-the-art modeling of pipeflow and internal erosion. The studies reviewed include those that examined the process of slope stability as affected by the clogging of soil pipes, the process of gullies forming due to mass failures caused by flow into discontinuous soil pipes, and the process of gully initiation by tunnel collapse due to pipes enlarging by internal erosion. In some of these studies, the soil pipes were simulated with perforated tubes placed in the soil, while in others the soil pipes were formed from the soil itself. Analytical solutions of the excess shear stress equation have been applied to experimental data of internal erosion of soil pipes to calculate critical shear stress and erodibility properties of soils. The most common numerical models for pipeflow have been based on Richards' equation, with the soil pipe treated as a highly conductive porous medium instead of a void. Incorporating internal erosion into such models has proven complicated due to enlargement of the pipe with time, turbulent flow, and episodic clogging of soil pipes. These studies and modeling approaches are described, and gaps in our understanding of pipeflow and internal erosion processes and our ability to model these processes are identified, along with recommendations for future research.

TI IN SITU SOIL PIPEFLOW EXPERIMENTS ON CONTRASTING STREAMBANK SOILS SO TRANSACTIONS OF THE ASABE LA English DT Article DE Erodibility; Internal erosion; Shear stress; Soil pipe; Streambank ID SEEPAGE EROSION; FLOW; TRANSPORT; SEDIMENT; SLOPE AB Soil piping has been attributed as a potential mechanism of instability of embankments and streambanks. Limited field work has been conducted on quantifying and modeling pipeflow and internal erosion processes in the field with either natural or artificially created soil pipes. This research utilized an innovative constant-head trench system to conduct constant-head soil pipe experiments in two contrasting streambanks: Dry Creek in northern Mississippi and Cow Creek in northern Oklahoma. Experiments included open pipes, in which the soil pipe was directly connected to the constant-head trench and open at the streambank face, and clogged pipes, which involved plugging the outlet of the soil pipe using soil excavated adjacent to the pipe. A tensiometer network was used to measure soil water pressures surrounding open and clogged pipe outlets on the streambank face. When pipeflow occurred, flow and sediment samples were collected using flow collection pans to quantify sediment concentrations. Flow and sediment data were used with an existing turbulent pipeflow and internal erosion model to estimate erodibility and critical shear stress properties of the soils, which were subsequently compared to similar properties derived from jet erosion tests. Clogged soil pipes resulted in pore water pressure increases in the soil adjacent to the pipe, which generally remained below saturation during these experimental periods, except at locations close to the plug. Depending on the density of the plugged soil material, the clogged soil pipes either burst, resulting in turbulent pipeflow, or were manually punctured to establish pipeflow. Calibrated critical shear stress from the turbulent pipeflow and internal erosion model matched that observed from jet erosion tests for the less erodible soils on the Dry Creek streambank, where sediment concentrations were consistently below 2 g L-1 even with fairly large hydraulic gradients on the pipe (0.3 m m(-1)). Calibrated erodibility coefficients were much smaller than those measured with jet erosion tests. For the more erodible streambank soils of Cow Creek, sediment concentrations approached 40 g L-1. There is a need for improved pipeflow modeling that accounts for rapidly changing pipe geometries, partially filled soil pipes, and pipeflow/soil matrix interactions. C1 [Midgley, T. L.; Fox, G.

TI DERIVING PARAMETERS OF A FUNDAMENTAL DETACHMENT MODEL FOR COHESIVE SOILS FROM FLUME AND JET EROSION TESTS SO TRANSACTIONS OF THE ASABE LA English DT Article DE Cohesive soils; Detachment rate model; Erodibility; Flume; Jet erosion test; Shear stress ID SURFACE ERODIBILITY; EARTHEN CHANNELS; COMPACTED SOILS; TURBULENT-FLOW; HIGH STRESSES; SCOUR AB The erosion rate of cohesive soils is commonly quantified using the excess shear stress model, which is dependent on two major soil parameters: the critical shear stress (tau(c)) and the erodibility coefficient (k(d)). A submerged jet test (jet erosion test, or JET) is one method that has been developed for measuring these parameters. The disadvantage of using the excess shear stress model is that parameters tau(c) and k(d) change according to erosion conditions, such as soil structure, soil orientation, type of clay, presence of roots, and seepage forces. A more mechanistically based detachment model, called the Wilson model, is proposed in this article for modeling the erosion rate of soils using hydraulic analysis of a JET. The general framework of the Wilson model is based on two soil parameters (b(0) and b(1)). The objectives of this study were to: (1) develop methods of analysis of the JET to determine parameters b(0) and b(1) for the Wilson model in a similar fashion to the previous methodology developed for open-channel flow, and (2) compare the excess stress model parameter (k(d)) and the Wilson model parameters (b(0) and b(1)) determined from the flume tests and JETs for two cohesive soils. Flume tests, treated as the standard test method, and original and "mini" JETs were conducted on two soils to independently measure the excess shear stress model parameter (k(d)) and the Wilson model parameters (b(0) and b(1)). Soil samples of two cohesive soils (silty sand and clayey sand soils) were packed in a soil box for the flume tests and the JETs at water contents ranging from 8.7% to 18.1%. No statistically significant differences were observed for the excess shear stress model parameter (k(d)) and for the Wilson model parameters (b(0) and b(1)) when determined from the flume tests and JET devices, except for b(1) with the original JET. The Wilson model is advantageous in being a more mechanistic, fundamentally based erosion equation as compared to the excess shear stress model. The Wilson model can be used in place of the excess shear stress model with parameters that can be estimated using existing JET techniques. C1 [Al-Madhhachi, A.

The objective of this study was to compare several existing soil surface roughness indices and to test the use of the revised triangular prism surface area method (RTPM) to calculate the fractal dimension as a roughness index. A silty clay loam soil was sampled, sieved to four aggregate sizes, and each size was packed in soil trays in order to derive four different soil surface roughness classes. Rainfall simulations using an oscillating nozzle simulator were conducted for 90 min at 50.2 mm h(-1) average intensity. The surface microtopography was digitized by an instantaneous profile laser scanner before and after the rainfall application. Calculated roughness indices included random roughness, variogram sill and range, fractal dimension and fractal length using a fractional Brownian motion (fBm) model, variance and correlation length according to a Markov-Gaussian (MG) model, and fractal dimension using the RTPM. Random roughness is shown to be the best estimator to significantly distinguish soil surface roughness classes. When taking spatial dependency into account, the variogram sill was the best alternative. The fractal dimension calculated from the fBm model did not yield good results, as only short-range variations were incorporated. The MG variance described the large-scale roughness better than the parameters of the fBm model did. The fractal dimension from the RTPM performed well, although it could not significantly discriminate between all roughness classes. Since it covered a greater range of scales, we believe that it is a good estimator of the overall roughness. C1 [Vermang, J.; Cornelis, W.

TI A PHENOMENOLOGICAL STUDY OF SEDIMENT TRANSPORT IN SHALLOW OVERLAND FLOW SO TRANSACTIONS OF THE ASABE LA English DT Article DE Bed load transport; Saltation; Sediment movement; Sediment particle interactions; Shallow overland flow; Soil erosion ID WATER-STREAM; SALTATING PROCESS; GRAINS; PARTICLE; MOTION; BED; WALL AB Soil erosion is a highly complicated phenomenon consisting of many component processes. On upland areas, these processes are usually thought of as detachment and transport of soil particles by rainfall and surface flow. One of the most difficult processes to quantify is sediment transport. This process depends on a host of factors including sediment type, size, size distribution, and concentrations on one hand and the flow regime relative to rates and velocities on the other hand. The effect of all of these factors is influenced by soil surface cover and surface roughness conditions. The National Sedimentation Laboratory has in recent years conducted a series of basic laboratory studies to better understand sediment movement in shallow overland flow. These experiments involved super-critical flow regimes in a 7 m long and 10 cm wide channel in which sand-size material was seeded at the upstream end at controlled rates in a super-critical flow regime with Froude numbers > 1. Particle sizes were coarse sand (1000 to 1400 mu m), medium sand (600 to 850 mu m), and spherical glass beads (600 to 1000 mu m). Measurements included particle velocity and particle concentrations using photonic probes. Three modes of transport were noted: a saltation mode at low concentrations, sediment waves in which sediment moved in regularly spaced waves, and a meander mode. The latter two modes were attributed to particle interactions. The transported sediment was continuously collected at the downstream end by a rotating sampler. A curvilinear increase in transport rate was noted with an increase in seeding rate until a critical saltation limit was reached, after which a decrease in sediment movement occurred with the formation of organized sediment structures. The small structures were waves with spacings of the order of magnitude of tens of particle diameter, while the larger-scale meander had wavelengths of hundreds of particle diameters. The measured pseudo-equilibrium transport rates were smallest in the meander mode, followed by the wave mode. A relationship was obtained that described the transition from the saltation mode to the wave mode in terms of a critical solid concentration. C1 [Roemkens, M. J.

TI EFFECT OF TOPOGRAPHIC CHARACTERISTICS ON COMPOUND TOPOGRAPHIC INDEX FOR IDENTIFICATION OF GULLY CHANNEL INITIATION LOCATIONS SO TRANSACTIONS OF THE ASABE LA English DT Article DE Compound topographic index; DEM resolution; Gully erosion; Random field simulation; Watershed models ID EROSION; DEPOSITION AB Sediment loads from gully erosion contribute to water quality problems, reduction in crop productivity by removal of nutrient-rich topsoil, and damage to downstream ecosystems. The identification of areas with high potential for gully channel development is often performed using spatially derived stream power estimates from second-order topographic indices, such as the compound topographic index (CTI). The utilization of CTI to identify where gullies develop is affected by field and local topographic characteristics and DEM resolution. In this study, the effect of overall terrain slope, local relief variance, and raster grid cell size on CTI cumulative distribution values was investigated using theoretical and observed catchment methodology. In the theoretical analysis, stochastic methods were used to generate simulated catchments to quantify the influence of overall terrain slope, local relief variance, and raster grid cell size (each considered individually). The observed methodology used three sites with distinct topographic characteristics, measured gully channels, and high-resolution topographic information. Raster grids for the three observed study sites were generated at varying raster grid cell sizes. Critical CTI values were determined through comparison of measured gully thalwegs with threshold CTI raster grids of the observed watersheds at different resolutions. Results from the theoretical investigation indicate that CTI values were linearly influenced by changes in relief variance and overall slope, while variations in raster grid cell size caused an inverse power variation in CTI values. In addition, variations in raster grid cell size, produced changes in cumulative distributions of the top 0.1% CTI values. The use of normalized CTI values (CTIn) produced merged cumulative distribution curves when varying overall slope, terrain relief variance, and to a lesser degree DEM resolution. Similar findings were obtained from the analysis of observed catchments. When DEM resolution varied, the differences in critical CTIn values in the same field were significantly reduced when compared to original critical CTI values, although differences were not fully eliminated. Normalization of the CTI cumulative distributions improved comparisons between different sites with distinct drainage area sizes and topographic characteristics, providing a possible alternative for investigations of large watersheds with more than one topographic characteristic. Results suggest that a normalized critical CTI between 1 and 2 could be used for the identification of areas with high potential for gully development. Knowing where gullies develop is important in understanding the effect of conservation practices on soil erosion through the use of field-scale and watershed-scale simulation models. Effective watershed management plans depend on this information to target the placement of conservation practices for the efficient use of available resources. C1 [Momm, H.

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

TI EROSION PROCESSES AND PREDICTION WITH WEPP TECHNOLOGY IN FORESTS IN THE NORTHWESTERN U.S. SO TRANSACTIONS OF THE ASABE LA English DT Article DE ATV impacts; Channel erosion; Forest roads; Logging; Mass wasting; Wildfire ID WESTERN UNITED-STATES; POSTFIRE HILLSLOPE EROSION; SUB-ALPINE FORESTS; PRESCRIBED FIRE; NORTHERN IDAHO; ROAD EROSION; SOIL-EROSION; MODEL; SEDIMENT; WATER AB In the northwestern U.S., the greatest amounts of forest erosion usually follow infrequent wildfires. Sediment from these fires is gradually routed through the stream system. The forest road network is usually the second greatest source of sediment, generating sediment annually. Erosion rates associated with timber harvest, biomass removal, and prescribed fire are generally minimal with current management practices. Landslides and debris flows can contribute significant amounts of sediment during infrequent wet years or following wildfire. A relatively new source of sediment in forested watersheds is recreation, particularly all-terrain vehicle trails. Stream channels store and route sediment; in the absence of channel disturbance, they tend to reach an equilibrium condition in which sediment entering a given reach is balanced by sediment carried downstream. At times, sediment from roads, wildfire, or landslides may accumulate in channels until higher flow rates, often associated with rainfall on melting snow, flush it downstream. Prediction tools are needed to aid forest managers in estimating the impacts of soil erosion on upland productivity and the risks of sediment delivery to downstream habitats and water users. Tools have been developed to aid in estimating long-term, low-level erosion in undisturbed forests and delivery of sediment from roads, and tools for estimating short-term, event-driven sediment from disturbed forests have also been developed. Online and GIS interfaces were developed using the Water Erosion Prediction Project (WEPP) model, including soil, vegetation, and climate databases. The online interfaces were developed to allow users to more easily predict soil erosion and sediment delivery for a wide range of climatic and forest conditions, including roads, fires, and timber harvest. There have been ongoing efforts to improve the online watershed interface to better model channel processes, road networks, and spatial variability associated with wildfire and weather.

TI APPLYING ONLINE WEPP TO ASSESS FOREST WATERSHED HYDROLOGY SO TRANSACTIONS OF THE ASABE LA English DT Article DE Forest watershed; GIS interface; Hydrologic modeling; Online WEPP; Water erosion ID SOIL-EROSION; MODEL; RUNOFF; ROADS AB A new version of the online Water Erosion Prediction Project (WEPP) GIS interface has been developed to assist in evaluating sediment sources associated with forests and forest management within the Great Lakes basin. WEPP watershed structure and topographical inputs for each watershed element are generated from the USGS 30 m National Elevation Dataset (NED), soil inputs are automatically retrieved from the USDA-NRCS SSURGO database, and land use and management inputs are selected from the WEPP database based on the USGS National Land Cover Database 2001 (NLCD2001). Additionally, ground cover and soil properties of the WEPP management and soil input files can be customized to represent site-specific conditions. Daily climate inputs are generated from long-term climate parameters using CLIGEN, a stochastic climate generator embedded in the online interface. Alternatively, a registered user can upload and use observed daily climate data for online WEPP simulation. Long-term observational data, including runoff and water chemistry, from two mature forest watersheds of the Fernow Experimental Forest in West Virginia were used to assess the online WEPP GIS interface. Online WEPP simulations were carried out using both observed and CLIGEN-generated climate inputs, and model performance was examined by comparing simulated and observed runoff and simulated and estimated (from measured water chemistry data) sediment yield. The online WEPP reasonably simulated average annual runoff and the annual maximum runoff series for both watersheds, but overpredicted sediment yield for the annual average and annual maximums. The online WEPP simulation results accurately reflected the differences between the two watersheds in their hydrological characteristics. The online WEPP GIS interface is a user-friendly, web-based computer package that can be used by scientists, researchers, and practitioners as a cost-effective simulation tool for watershed management.

TI GEOSPATIAL APPLICATION OF THE WATER EROSION PREDICTION PROJECT (WEPP) MODEL SO TRANSACTIONS OF THE ASABE LA English DT Article DE Geographic information systems; Prediction; Soil erosion; WEPP ID UNITED-STATES; INTERFACES; GIS AB At the hillslope profile and/or field scale, a simple Windows graphical user interface (GUI) is available to easily specify the slope, soil, and management inputs for application of the USDA Water Erosion Prediction Project (WEPP) model. Likewise, basic small watershed configurations of a few hillslopes and channels can be created and simulated with this GUI. However, as the catchment size increases, the complexity of developing and organizing all WEPP model inputs greatly increases due to the multitude of potential variations in topography, soils, and land management practices. For these types of situations, numerical approaches and special user interfaces have been developed to allow for easier WEPP model setup, utilizing either publicly available or user-specific geospatial information, e. g., digital elevation models (DEMs), geographic information system (GIS) soil data layers, and GIS land use/land cover data layers. We utilize the Topographic Parameterization (TOPAZ) digital landscape analysis tool for channel, watershed, and subcatchment delineation and to derive slope inputs for each of the subcatchment hillslope profiles and channels. A user has the option of specifying a single soil and land management for each subcatchment or utilizing the information in soils and land use/land cover GIS data layers to automatically assign those values for each grid cell. Once WEPP model runs are completed, the output data are analyzed, results interpreted, and maps of spatial soil loss and sediment yields are generated and visualized in a GIS. These procedures have been used within a number of GIS platforms including GeoWEPP, an ArcView/ArcGIS extension that was the first geospatial interface to be developed in 2001. GeoWEPP allows experienced GIS users the ability to import and utilize their own detailed DEM, soil, and/or land use/land cover information or to access publicly available spatial datasets. A web-based GIS system that used MapServer web GIS software for handling and displaying the spatial data and model results was initially released in 2004. Most recently, Google Maps and OpenLayers technologies have been integrated into the web WEPP GIS software to provide significant enhancements. This article discusses in detail the logic and procedures for developing the WEPP model inputs, the various WEPP GIS interfaces, and provides example real-world geospatial WEPP applications. Further work is ongoing in order to expand these tools to allow users to customize their own inputs via the internet and to link the desktop GeoWEPP with the web-based GIS system. C1 [Flanagan, D.

TI MODIFYING WEPP TO IMPROVE STREAMFLOW SIMULATION IN A PACIFIC NORTHWEST WATERSHED SO TRANSACTIONS OF THE ASABE LA English DT Article DE Baseflow; Deep seepage; Forest watershed; Hydrologic modeling; Subsurface lateral flow; Surface runoff; WEPP ID FLOW RECESSION; BASE-FLOW; NORTHERN IDAHO; HILLSLOPE; FOREST; CATCHMENT; STORAGE; MODEL; STEEP; GENERATION AB The assessment of water yield from hillslopes into streams is critical in managing water supply and aquatic habitat. Streamflow is typically composed of surface runoff, subsurface lateral flow, and groundwater baseflow; baseflow sustains the stream during the dry season. The Water Erosion Prediction Project (WEPP) model simulates surface runoff, subsurface lateral flow, soil water, and deep percolation. However, to adequately simulate hydrologic conditions with significant quantities of groundwater flow into streams, a baseflow component for WEPP is needed. The objectives of this study were (1) to simulate streamflow in the Priest River Experimental Forest in the U. S. Pacific Northwest using the WEPP model and a baseflow routine, and (2) to compare the performance of the WEPP model with and without including the baseflow using observed streamflow data. The baseflow was determined using a linear reservoir model. The WEPP-simulated and observed streamflows were in reasonable agreement when baseflow was considered, with an overall Nash-Sutcliffe efficiency (NSE) of 0.67 and deviation of runoff volume (D-v) of 7%. In contrast, the WEPP simulations without including baseflow resulted in an overall NSE of 0.57 and D-v of 47%. On average, the simulated baseflow accounted for 43% of the streamflow and 12% of precipitation annually. Integration of WEPP with a baseflow routine improved the model's applicability to watersheds where groundwater contributes to streamflow. C1 [Srivastava, A.; Dobre, M.; Wu, J.

TI SPATIAL APPLICATION OF WEPS FOR ESTIMATING WIND EROSION IN THE PACIFIC NORTHWEST SO TRANSACTIONS OF THE ASABE LA English DT Article DE Air quality; GIS; model; WEPS; wind erosion ID SYSTEM AB The Wind Erosion Prediction System (WEPS) is used to simulate soil erosion by wind on cropland and was originally designed to run simulations on a field scale. This study extended WEPS to run on multiple fields (grid cells) independently to cover a large region and conducted an initial investigation to assess how well WEPS performed in that environment by comparing simulations for two historical dust events with field observations and satellite images in the Columbia Plateau region of Washington. We modified the WEPS source code to allow it not only to run on multiple grid cells but also to save the state of the simulation so that it can be re-initiated from that state in future runs, allowing the model to be started and then stepped through time incrementally under various future climate or forecast weather scenarios. We initially ran WEPS on the entire state of Washington, with the entire Pacific Northwest region as our ultimate target area, to provide PM10 and eventually PM2.5 emissions from wind erosion events as input to the chemical transport model CMAQ, which is used by the AIRPACT regional air quality modeling system for the Pacific Northwest. Three principal inputs to WEPS are meteorological data, soil data, and crop management practices. These data, at a 1 km x 1 km grid cell resolution, are the basic input data for running the spatially distributed model. The climatic data from a three-year period were stochastically generated based on statistical representations of past meteorological measurements from stations in the region and were used for initializing WEPS, and then a three-day set of meteorological data corresponding with historical dust storm events were selected for simulation by WEPS of wind erosion of cropland in the state of Washington. The crop management data were selected based on the land use and USDA Natural Resources Conservation Service (NRCS) crop management zones, and the soil data were derived from the NRCS SSURGO database. We aggregated the outputs from 1 km x 1 km grid cells into 12 km x 12 km grid cells for easier visualization and then mapped the total surface soil erosion, suspension, and PM10 emissions for each 12 km x 12 km grid cell. This study shows that WEPS can be successfully extended to run from one field grid cell to multiple field grid cells, and the model can identify regions with high potential for soil erosion by wind. It also demonstrates that WEPS can be used for real-time monitoring of soil erosion and air quality in a large region if actual and forecast weather inputs are available.

TI APPLICATION OF THE WIND EROSION PREDICTION SYSTEM IN THE AIRPACT REGIONAL AIR QUALITY MODELING FRAMEWORK SO TRANSACTIONS OF THE ASABE LA English DT Article DE Air quality; GIS; PM10; Regional modeling; Wind erosion ID COLUMBIA PLATEAU; PACIFIC-NORTHWEST; WINDBLOWN DUST; CLIMATE-CHANGE; UNITED-STATES; AGRICULTURAL LANDS; WASHINGTON-STATE; LOESSIAL SOILS; PM10 LOSS; WEPS AB Wind erosion of soil is a major concern of the agricultural community, as it removes the most fertile part of the soil and thus degrades soil productivity. Furthermore, dust emissions due to wind erosion degrade air quality, reduce visibility, and cause perturbations to regional radiation budgets. PM10 emitted from the soil surface can travel hundreds of kilometers downwind before being deposited back to the surface. Thus, it is necessary to address agricultural air pollutant sources within a regional air quality modeling system in order to forecast regional dust storms and to understand the impact of agricultural activities and land-management practices on air quality in a changing climate. The Wind Erosion Prediction System (WEPS) is a new tool in regional air quality modeling for simulating erosion from agricultural fields. WEPS represents a significant improvement, in comparison to existing empirical windblown dust modeling algorithms used for air quality simulations, by using a more process-based modeling approach. This is in contrast with the empirical approaches used in previous models, which could only be used reliably when soil, surface, and ambient conditions are similar to those from which the parameterizations were derived. WEPS was originally intended for soil conservation applications and designed to simulate conditions of a single field over multiple years. In this work, we used the EROSION submodel from WEPS as a PM10 emission module for regional modeling by extending it to cover a large region divided into Euclidean grid cells. The new PM10 emission module was then employed within a regional weather and chemical transport modeling framework commonly used for comprehensive simulations of a wide range of pollutants to evaluate overall air quality conditions. This framework employs the Weather Research and Forecasting (WRF) weather model along with the Community Multi-scale Air Quality (CMAQ) model to treat ozone, particulate matter, and other air pollutants. To demonstrate the capabilities of the WRF/EROSION/CMAQ dust modeling framework, we present here results from simulations of dust storms that occurred in central and eastern Washington during 4 October 2009 and 26 August 2010. Comparison of model results with observations indicates that the modeling framework performs well in predicting the onset and timing of the dust storms and the spatial extent of their dust plumes. The regional dust modeling framework is able to predict elevated PM10 concentrations hundreds of kilometers downwind of erosion source regions associated with the windblown dust, although the magnitude of the PM10 concentrations are extremely sensitive to the assumption of surface soil moisture and model wind speeds. Future work will include incorporating the full WEPS model into the regional modeling framework and targeting field measurements to evaluate the modeling framework more extensively. C1 [Chung, S.

The resultant data will eventually be incorporated into models such as the Wind Erosion Prediction System (WEPS). A replicated field experiment was conducted in the fall of 2010 on two soils that dominate the military training grounds at Fort Riley, Kansas. Treatments consisted of two vehicle types and three levels of vehicle passes. We used an Abrams M1A1 tank and a High-Mobility Multipurpose Wheeled Vehicle (i.e., Humvee), representing tracked and wheeled military vehicles, respectively. Bulk density, aboveground standing biomass, and plant cover were measured before and after vehicular traffic in the fall of 2010 as well as in the spring and summer of 2011. Samples were taken from curved, straight, and cross-over sections of the vehicle tracks. A mixed-model analysis of variance of these data indicated that the overall mean bulk density under the M1A1 was significantly greater than under the Humvee (p <= 0.05). In general, as the number of passes increased, the bulk density under the M1A1 increased significantly (p <= 0.05), but the increases under the Humvee were not significant (p <= 0.05). Bulk densities were significantly greater in the curved part of the tracks than the straight part of the tracks. Reduction in standing biomass and vegetation cover was more severe on average under the M1A1 than under the Humvee (although not significant at p <= 0.05). For both vehicles, biomass and cover were affected more at the curved sections of the track than the straight sections (significant at p <= 0.05). Comparison of spring and fall bulk density data showed significant differences at the 0-5 cm and 5-10 cm depths, indicating that the winter freeze and thaw cycles loosened the top soil layers. Subsequent growth showed severe reduction in grass biomass growth in the curved sections of the tracked vehicle paths. Growth in forb species was not significantly affected. C1 [Retta, A.; Wagner, L.

However, in most watersheds, runoff is produced by saturation excess processes. In this article, we improve an earlier saturation excess erosion model that was only tested on a limited basis, in which runoff and erosion originated from periodically saturated and severely degraded areas, and apply it to five watersheds over a wider geographical area. The erosion model is based on a semi-distributed hydrology model that calculates saturation excess runoff, interflow, and baseflow. In the development of the erosion model, a linear relationship between sediment concentration and velocity in surface runoff is assumed. Baseflow and interflow are sediment free. Initially during the rainy season in Ethiopia, when the fields are being plowed, the sediment concentration in the river is limited by the ability of the surface runoff to move sediment. Later in the season, the sediment concentration becomes limited by the availability of sediment. To show the general applicability of the Saturation Excess Erosion Model (SEEModel), the model was tested for watersheds located 10,000 km apart, in the U. S. and in Ethiopia. In the Ethiopian highlands, we simulated the 1.1 km(2) Anjeni watershed, the 4.8 km(2) Andit Tid watershed, the 4.0 km(2) Enkulal watershed, and the 174,000 km(2) Blue Nile basin. In the Catskill Mountains in New York State, the sediment concentrations were simulated in the 493 km(2) upper Esopus Creek watershed. Discharge and sediment concentration averaged over 1 to 10 days were well simulated over the range of scales with comparable parameter sets. The Nash-Sutcliffe efficiency (NSE) values for the validation runs for the stream discharge were between 0.77 and 0.92. Sediment concentrations had NSE values ranging from 0.56 to 0.86 using only four calibrated sediment parameters together with the subsurface and surface runoff discharges calculated by the hydrology model. The model results suggest that correctly predicting both surface runoff and subsurface flow is an important step in simulating sediment concentrations. C1 [Tilahun, S. A.; Steenhuis, T.

TI SEASONAL CHANGE OF WEPP ERODIBILITY PARAMETERS FOR TWO FALLOW PLOTS ON A PALOUSE SILT LOAM SO TRANSACTIONS OF THE ASABE LA English DT Article DE Critical shear; Frozen soil; Rill erodibility; Soil erosion; Thawing soil; WEPP ID FREEZE-THAW; EROSION; MODEL; INFILTRATION; RUNOFF; FROZEN; SOILS; ROADS AB In cold regions, frozen soil has a significant influence on runoff and water erosion. In the U. S. Inland Pacific Northwest, major erosion events typically occur during winter as frozen soil thaws and exhibits low cohesion. Previous applications of the WEPP (Water Erosion Prediction Project) model to a continuous bare tilled fallow (CBF) runoff plot at the Palouse Conservation Field Station (PCFS) in southeastern Washington State showed that WEPP reproduced the occurrence of the large erosion events, but the amount of sediment yield was either under- or overestimated. The inability of WEPP to reproduce the magnitude of field-observed erosion events at the PCFS suggests the need for an examination of the dynamic changes in soil erosion properties and for improving the representation of such dynamics. The objective of this study was to evaluate the seasonal changes of rill erosion parameters for two CBF runoff plots at the PCFS. Field-observed runoff and erosion events during 1984-1990 were used to estimate WEPP hydraulic and erosion parameters, including soil effective hydraulic conductivity, critical shear stress (tau(c)), and rill erodibility (K-r). The parameters for each event were best-fitted using WEPP single-event simulations to reproduce the observed runoff and sediment yield on both plots. The results suggest that the adjustment factors for tau(c) and K-r of frozen and thawing soils in the WEPP model could be modified to better describe the changes of these parameters in winter.

TI EFFECTS OF TOPOGRAPHIC FEEDBACK ON EROSION AND DEPOSITION PREDICTION SO TRANSACTIONS OF THE ASABE LA English DT Article DE Deposition; Ephemeral gully; Erosion; GIS; Grass hedge; LiDAR; RUSLE; Vegetative barrier ID DIGITAL ELEVATION MODELS; LANDSCAPE EVOLUTION; EPHEMERAL GULLIES; AGRICULTURAL LAND; TILLAGE EROSION; SEDIMENT YIELD; SOIL-EROSION; RUNOFF; WATER; HEDGES AB Soil erosion and depositional processes result in changes in topographic and soil profile properties over time. In spite of this, few current soil erosion models account for these changes. To begin to address this deficiency, a spatially distributed version of RUSLE2 was developed and used in combination with the tillage erosion model TELEM. These models were applied to a 6.6 ha research watershed near Treynor, Iowa, where runoff and sediment yield were measured from 1975 to 2002. The watershed contained a grassed waterway, and similar to 1 m wide grass hedges were established in 1991, with 15.4 m intervals between the grass hedges. Beginning in 1996, no-till management replaced conventional tillage management in the watershed. Using a 3 m raster DEM, concentrated flow channels that ended RUSLE2 hillslope profiles were delineated wherever contributing areas exceeded 600 m(2). Average monthly runoff and sediment delivery to concentrated flow areas were compared with measured monthly runoff and sediment delivery at the watershed outlet. For conventional tillage, monthly runoff patterns reasonably matched observations, but measured watershed sediment yield was lower than RUSLE2-predicted hillslope sediment delivery, suggesting that sediment was deposited in the grassed waterway. Grass hedges reduced sediment yield similarly in the RUSLE2 estimates and the measured watershed sediment yield. Conversion to no-till had a much greater impact in reducing RUSLE2 estimates of hillslope erosion than it did on measured watershed sediment yield, suggesting that ephemeral gully erosion remained an important sediment source in this watershed under no-till conditions. To assess the potential influence of distributed patterns of soil erosion and deposition behind the hedges on future erosion estimates, the terrain elevation was modified by summing estimates of water and tillage erosion and deposition that would be expected from 50 years of conventional tillage. As expected, reduced slope gradients generally reduced future erosion. The lack of consideration of erosion or deposition in concentrated flow channels limited the ability of the modeling scheme to reinforce existing ephemeral gully channels. C1 [Dabney, S.

TI COMPARISON OF ATMOSPHERIC STABILITY METHODS FOR CALCULATING AMMONIA AND METHANE EMISSION RATES WITH WINDTRAX SO TRANSACTIONS OF THE ASABE LA English DT Article DE Air emissions; Ammonia; Inversion dispersion model; Methane ID INVERSE-DISPERSION TECHNIQUE; GAS EMISSIONS; FEEDYARD; FEEDLOT; FARMS AB Inverse dispersion models are useful tools for estimating emissions from animal feeding operations, waste storage ponds, and manure application fields. Atmospheric stability is an important input parameter to such models. The objective of this study was to compare emission rates calculated with a backward Lagrangian stochastic (bLS) inverse-dispersion model (WindTrax) using three different methods for calculating atmospheric stability: sonic anemometer, gradient Richardson number, and Pasquill-Gifford (P-G) stability class. Ammonia and methane emission data from a compost yard at a 10,000-cow dairy were used for the comparisons. Overall, average emission rates were not significantly different among the stability methods. Emission rates correlated well between the sonic and other methods (r(2) > 0.79, p < 0.001). The slopes of the regression lines between the sonic and Richardson methods were 0.95 and 1.0 for CH4 and NH3, respectively. The regression line slopes for the P-G method were about 1.9 for CH4 and 1.6 for NH3, which means emission rates predicted with the P-G method tended to be 50% to 100% greater than rates predicted with sonic anemometer data. Based on this limited data set, using the gradient Richardson method to represent atmospheric stability resulted in emission rates that more closely matched emission rates from the sonic method. Considering the amount of variability inherent in emissions calculations, a three-dimensional sonic anemometer should be used, if possible, to directly provide the necessary data to calculate parameters representing wind properties, rather than inferring values from other stability classification methods.

TI EFFECT OF POND ASH ON PEN SURFACE PROPERTIES SO TRANSACTIONS OF THE ASABE LA English DT Article DE Animal waste; Beef cattle; Bioenergy; Biosolids; Combustion; Energy recovery; Land application; Manure; Renewable energy; Waste management ID FEEDLOT MANURE; CATTLE MANURE AB The maintenance of feedlot pen surfaces, which includes removal of manure and replacement of fill soil, is a time-consuming and expensive process. Pond ash (PA), a by-product of coal-fired electrical generation, has been proposed as a feedlot pen surface amendment because of its foundational support characteristics. A study was conducted to compare the performance of PA-surfaced pens to traditional soil-surfaced (SS) pens. Four of eight SS pens (7.3 m x 20.7 m) were excavated to a depth of 0.5 m and resurfaced with PA. The remaining four pens were kept as SS. Eight heifers were housed in each pen (19 m(2) head(-1)) for four feeding cycles that ranged from 73 to 172 days. Following each feeding cycle, the animals were removed and the pens were cleaned. A subsample of the accumulated manure was removed from each pen for analysis of total mass (TM), total solids (TS), volatile solids (VS), percent volatile solids (VS%), moisture, and ash content. Higher heating value (HHV) was estimated using the VS% and moisture content. As compared to the SS pens, surfacing pens with PA reduced TM by 34%, TS by 34%, and ash content by 46%. PA increased VS% by 70% and HHV by 75%. Restoring the PA-surfaced pens to the original grade required only 25% of the amount of fill material required for the SS pens. However, there were no differences in the total amount of VS removed. Harvested feedlot surface material (FSM) from the PA pens was more nutrient and energy dense, based on the increased VS% of the collected material. The increased density improved the economics of transport and handling, and allowed for greater energy recovery. In addition, the PA pens were less erodible than the SS pens. C1 [Woodbury, B.

Design/methodology/approach - The estimation procedure used in this study is implemented in three steps: first, the price/unit value information is estimated; second, the parameters for a set of demand systems are estimated; and third, the J-test and likelihood ratio testing are used to determine the most suitable model for the data set. Findings - The results indicate that households spend more on apparel than home textiles and other textile products if they purchase textile products from small stores. It also indicates that they would spend more on home textiles and other textiles if they purchase from chain stores and supermarkets. Originality/value - The estimation of Chinese textile consumption presents a significant challenge to both academic researchers and industry, due to China's large population, income inequality, different consumption channels, and other related issues. First, the results presented in the paper provide a clear indication for textile producers, exporters, and others to choose their distribution channels to target specific customers; second, the disaggregated textile expenditure and price elasticity estimates from this article can be used in various analytical procedures (i.e. simulation models) to evaluate the welfare effects of domestic policies and international trade policies. Quantification of the welfare impacts of domestic policies and international trade policies would be more meaningful if disaggregate textile elasticity estimates are used in simulation models.

TI Vermont Stumpage Price Trends Revisited: With Comparisons to New Hampshire SO FOREST PRODUCTS JOURNAL LA English DT Article AB Our objective was to describe the trends of Vermont stumpage prices for major sawtimber species and products over the approximately last quarter century and propose a likely explanation of changes that we observed. Annual percentage rates of change (APR) were estimated for 10 forest products in Vermont from the third quarter of 1981 (1981Q3) to the first quarter of 2007 (2007Q1) when the price series was discontinued. In addition, we tested for changes in the percentage rate within the period. We found differences in the trend of APR between hardwood sawtimber and softwood sawtimber. With one exception, price trends differed significantly between 1981Q3 to 1992Q2 and 1992Q3 to 2007Q1 for inflation-adjusted (real) hardwood sawtimber prices. There were no differences in price trends for any of the softwood sawtimber species between the two periods. Real price trends for pulpwood and firewood were similar to those for hardwood sawtimber. We also examined stumpage price trends for selected species in adjacent New Hampshire from 1985Q1 to 2011Q1. Stumpage price trends for like species and proximate time periods in Vermont and New Hampshire were similar, but no statistical tests were done. The direction of trend (positive or negative) was the same for sugar maple, red oak, yellow birch, and white pine, and the magnitude of APR was similar for sugar maple, yellow birch, and white pine.

TI Boron Diffusion in Surface-Treated Framing Lumber SO FOREST PRODUCTS JOURNAL LA English DT Article ID WESTERN HEMLOCK; DOUGLAS-FIR; WOOD; PENETRATION; PRESERVATIVES; PERFORMANCE AB The extent of boron penetration in framing lumber treated by spray applications during construction is not well quantified. This study evaluated the effect of formulation and concentration on diffusion of boron in lumber specimens that were equilibrated in conditions that produced wood moisture contents of 18 to 21 percent. One set of specimens was pressure treated with water before equilibration. Borate solutions were prepared from powdered disodium octaborate tetrahydrate (DOT) or from two commercial glycol-borate formulations and applied with a garden-type sprayer. The DOT solution was applied at a 15 percent concentration, while the glycol-borate formulations were applied at 15 and 23 percent concentrations. Boron penetration was evaluated after 6, 13, and 26 weeks and boron retention after 26 weeks of diffusion. Boron penetration was observed for all treatments and progressed for the duration of the study. There was no significant penetration difference between the powdered DOT and glycol-borate solutions when they were applied at the same (15%) DOT concentration. However, after 6 weeks, the glycol-borate solutions applied at the 23 percent DOT concentration produced significantly greater depth of penetration than the solutions applied at the 15 percent concentration. The exception was the 15 percent DOT solution applied to the specimens that had been wetted and then dried down to equilibrium conditions. These specimens had the greatest penetration, possibly as a result of their higher equilibrium moisture content. Retention analysis revealed that the glycol-borate solutions applied at the 23 percent DOT concentration yielded significantly greater boron retentions in the outer assay zone. This effect was less apparent for the inner assay zones. Although boron retentions in the outer assay zone were below those standardized for pressure-treated wood, in some cases they exceeded reported concentrations needed for protection against termites and decay fungi.

Electrode responses were measured with five ISEs for each of NO3-N, P, and K and were normalized using the baseline correction and two-point normalization methods developed in our previous work. The array of ISEs fabricated with new membranes and cobalt rod, in conjunction with the previously developed normalization methods and calibration models, accurately estimated NO3-N, P, and K in solution without need to recalibrate the ISE system through standard laboratory analysis of soil samples from the new test site. ISE-measured NO3-N, P, and K concentrations in Kelowna-based soil extracts were similar to those determined by standard instruments, validating the ability of the system to identify within-field macronutrient differences. The use of a calibration factor to adjust ISE measurements for the difference in extraction efficiency between Kelowna and standard extractants resulted in a slope near unity between soil NO3-N, P, and K concentrations determined by ISEs and standard methods. However, a relatively large offset in soil P concentration between calibrated ISEs and standard methods will require further investigation to identify the cause. This study showed that it was possible to transfer existing calibration equations to new membranes and electrodes through application of the baseline correction and two-point normalization methods and an adjustment for differences in extraction efficiency. This finding enhances the applicability of the ISE-based soil macronutrient sensing system and methodology for rapid soil analysis. C1 [Kim, H.

TI APEX CALIBRATION AND VALIDATION OF WATER AND HERBICIDE TRANSPORT UNDER US SOUTHERN ATLANTIC COASTAL PLAIN CONDITIONS SO TRANSACTIONS OF THE ASABE LA English DT Article DE APEX model; Calibration; Conventional tillage; Pesticide losses; Strip tillage; Subsurface lateral flow; Surface runoff; Validation ID RUNOFF CURVE NUMBERS; CONSERVATION TILLAGE; QUALITY SIMULATION; TILE FLOW; YIELD; MODEL; PRODUCTIVITY; IMPACT; SENSITIVITY; EVAPORATION AB Simulation models are widely used to assess water contamination risk associated with pesticide use and for evaluating effectiveness of agricultural conservation practices. Currently, the APEX (Agricultural Policy/Environmental eXtender) model is being used for this purpose in the USDA Conservation Effects Assessment Project (CEAP) Cropland National Assessment. In support of the CEAP modeling effort, APEX was calibrated and validated using a nine-year record (1999-2007) of crop yield, surface runoff, and tile outflow and an eight-year record (1999-2006) of soluble pendimethalin and fluometuron herbicide losses from fields in a cotton-peanut rotation located in the Atlantic Coastal Plain region of south-central Georgia. Conventional tillage and strip tillage were directly compared. Monthly surface runoff was calibrated by adjusting three variables: curve number index coefficient (CNIC), a driver of the USDA Natural Resources Conservation Service (NRCS) runoff curve number; runoff curve number for the average soil moisture condition 2 (CN2); and irrigation runoff ratio (IRR). Statistical performance criteria for monthly and annual results were r(2) > 0.5, NSE > 0.45, and PBIAS < 20%, based on prior modeling studies. Monthly runoff statistics showed r(2) values of 0.62 to 0.82 and met satisfactory criteria between observed and simulated surface runoff for both tillage types, with Nash-Sutcliffe efficiency (NSE) values of 0.62 to 0.80 and PBIAS values within +/-19% during the calibration and validation periods. Monthly subsurface lateral flow performance statistics for the strip-tilled plots were satisfactory during the calibration period but weak for the conventional tillage plots. Monthly performance statistics for fluometuron runoff for the conventional tillage plots were below satisfactory criteria. Other monthly statistics for fluometuron and pendimethalin losses were weak. Measured and predicted crop yield and annual runoff for both tillage systems were well aligned and met satisfactory statistical criteria. APEX performance was satisfactory for annual fluometuron soluble runoff for the conventionally tilled plots but not satisfactory for the strip-tilled plot with less runoff. The model's performance was unsatisfactory for annual subsurface lateral flow and fluometuron transport in subsurface lateral flow for both tillage systems. The percent bias statistical parameter (PBIAS) was within +/-20% for all annual mean correlations, indicating that APEX effectively replicated annual means for crop yield, runoff, subsurface lateral flow, and pesticide losses. Measured and simulated results of conservation tillage effects were in close agreement for decreased water and pesticide runoff as well as increased subsurface lateral flow and associated fluometuron losses. Although fluometuron losses in subsurface lateral flow approximately doubled with conservation tillage, loading was still small compared to fluometuron in runoff from the conventionally tilled plots. Results demonstrate APEX's strength in simulating runoff in this landscape, but less satisfactory results were obtained for pendimethalin runoff, subsurface lateral flow, and fluometuron losses in subsurface lateral flow.

TI IMPACTS OF GIN AND MILL CLEANING ON MEDIUM-LONG STAPLE STRIPPER-HARVESTED COTTON SO TRANSACTIONS OF THE ASABE LA English DT Article DE Cotton ginning; Cotton processing; Fiber quality; Lint; Stripper harvesting ID FIBER LENGTH DISTRIBUTION; NEPS AB The quality of upland cotton grown in the Texas Plains, which in good seasons constitutes nearly 40% of all U. S. cotton, has changed radically over the past decade. However, production practices, particularly pertaining to harvesting and ginning, remain largely unchanged, with a predominately stripper-harvested crop. Hence, the necessity to subject the lint to vigorous cleaning at the gin could adversely impact the use value of the cotton in high-value added applications more typically served by picker-harvested cotton. This research was conducted to provide a systemic analysis, combining perspectives from both the gin and the spinning mill, of the impacts of mechanical cleaning on the emerging stripper-harvested cotton with improved fiber properties that appear suitable for ring-spinning. Five cotton varieties grown over three seasons were processed through various sequences of gin and spinning mill cleaning processes. Analysis of the properties of individual fibers across the gin and spinning mill processing chain revealed significant interactions impacting fiber entanglements (neps), mean length, and short fiber content. Both neps and length distribution parameters appeared significantly impacted by fiber damage in both the ginning and spinning processes. However, the damage inflicted through both ginning and spinning may be a function of only fiber maturity. Mature cottons have lower fiber damage potential and appear to be less affected by the processes of lint cleaning and spinning preparation than immature cottons. The latter have higher fiber damage potential, which is reached even with minimal cleaning at the gin because if those immature fibers are preserved at the gin, they will ultimately break in spinning preparation.

The objectives of this research were to investigate the chemical and nutritional characteristics and determine effective separation methods of the peel and seed of commercial tomato pomace from hot and cold break processes. The chemical composition of pomace, including fatty acid content of the seed oil, and the nutritional quality, including amino acid profile of defatted seed, were determined. The impacts of dry and wet separation on physicochemical properties of the peel and seed were evaluated. Based on the results, the studied pomace samples were rich in nutrients, including fat (8.37% to 16.24%), protein (15.08% to 22.70%), insoluble dietary fiber (IDF) (48.49% to 64.75%), soluble dietary fiber (SDF) (8.91% to 10.04%), and lycopene (98.16 to 172.07 mg kg(-1)). The seed oil had total unsaturated fatty acid content up to 80.10%, and the defatted tomato seed contained six kinds of essential amino acids, with histidine, an essential amino acid for infants, as the most dominant (23.34%). Both the dry and wet separation methods were effective for separation of the studied pomace. However, wet separation caused significant loss of micronutrients. The study indicated that commercial tomato pomace can be separated without water and used to produce value-added products with high nutrients.

Child FV intake reflects many influences from multiple levels (e. g. internal to the child, family, school, and neighborhood). We have documented influences at each of these levels, but more definitive research in longitudinal samples remains to be conducted. Even though validated comprehensive models of influences on child FV intake in longitudinal studies are not available to guide intervention design for children of different ages, there has been an urgency to initiate chronic disease prevention interventions to mitigate the substantial health consequences. Effective interventions use known behavior change procedures to change the influences on FV intake enough to change the behavior, but few such interventions have demonstrated effectiveness at meaningful levels. Innovative methods need to be explored. Videogames for Health offer a medium that is attractive to children and shows promising results, especially for dietary behavior change. Exciting additional research is needed to clarify possible bidirectional influences between the environmental and individual influences on child intake with possible age-related differences in influence and in the optimal design of video games for dietary change.

In the darkness of soil, they mainly rely on root chemical exudations and, therefore, have evolved specific behaviours. Because of their impact on crop yield, most of our knowledge in belowground chemical ecology is biased towards soil-dwelling insect pests. Yet the increasing literature on volatile-mediated interactions in the ground underpins the great importance of chemical signalling in this ecosystem and its potential in pest control. Here, we explore the ecology and physiology of these chemically based interactions. An evolutionary approach reveals interesting patterns in the response of insects to particular classes of volatile or water-soluble organic compounds commonly emitted by roots. Food web analyses reasonably support that volatiles are used as long-range cues whereas water-soluble molecules serve in host acceptance/rejection by the insect; however, data are still scarce. As a case study, the chemical ecology of Diabrotica virgifera virgifera is discussed and applications of belowground signalling in pest management are examined. Soil chemical ecology is an expanding field of research and will certainly be a hub of our understanding of soil communities and subsequently of the management of belowground ecosystem services.

TI Iron oxide nanoparticle-based radio-frequency thermotherapy for human breast adenocarcinoma cancer cells SO BIOMATERIALS SCIENCE LA English DT Article ID AC-MAGNETIC-FIELD; CELLULAR UPTAKE; HYPERTHERMIA; CYTOTOXICITY; THERAPY; OXYGEN; BLOOD; SIZE AB Iron oxide nanoparticles (IONPs) with diameters of 15, 25, and 41 nm were evaluated as mediators of thermal cytotoxicity under radio-frequency (RF) exposure. The 25 nm IONPs were found to be the most efficient of the three in killing cancer cells at 350 kHz low-frequency RF irradiation. However, at a higher frequency of 13.56 MHz, 15 nm IONPs produced the highest percentage of cell death. Moreover, the killing effect was concentration-dependent in that a higher concentration of IONPs resulted in increased cellular death. Size-dependent internalization of IONPs in MCF-7 cells was quantified by using inductively coupled-plasma mass spectrometry (ICP-MS). Dark-field microscopy and transmission electron microscopy (TEM) revealed that MCF-7 cells internalize IONPs through endocytosis after 24 hours of incubation. In addition, after RF treatment, the cancer cells underwent the apoptosis process, and the level of reactive oxygen species (ROS) increased significantly after hyperthermia. Scanning electron microscopy (SEM) and TEM further established that the ultrastructure morphological changes in the cancer cells originated from the apoptosis process.

Numbers of viable colony-forming units (CPU) of Xanthomonas axonopodis pv. vignicola (Xav) and Clavibacter michiganensis subsp. michiganensis (Cmm) were estimated from cowpea and tomato seeds by soaking individual seeds in phosphate-buffered saline followed by dilution-plating onto MXP and CNS semi-selective agar medium, respectively. Xanthomonas euvesicatoria and Acidovorax citrulli populations were estimated by crushing individual seeds in buffer followed by plating of seed macerates onto appropriate media. For Pantoea stewartii subsp. stewartii, bacterial populations were estimated by comparing ELISA absorbance values from naturally-infested corn seed to standard curves created from a serial dilution of P. stewartii. Among the four vegetable bacterial pathogens (Xav, Cmm, X. euvesicatoria and A. citrulli), the population ranged from 10 to 4.1 x 10(8) CFU per seed in subsets of similar to 30 infested seeds. Bacterial populations of P. stewartii ranged from 1.6 x 10(5) to 8.5 x 10(8) CPU per seed. Based on the Shapiro-Wilk test, none of the bacterial populations were adequately described by a normal or log-normal distribution. No single distribution provided a good fit to all data sets, but most of the bacterial populations were adequately fit by the inverse Gaussian or Pearson (type 5) distributions that are highly and positively skewed. The highly skewed distributions of bacteria in infested seeds could have implications for determining appropriate sample sizes and statistical analysis methods for seed health testing.

TI Climate change and associated fire potential for the south-eastern United States in the 21st century SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE forest fires; Haines Index; KBDI ID WILDFIRE; ECOSYSTEMS AB Climate models indicate that the climate of the south-eastern US will experience increasing temperatures and associated evapotranspiration in the 21st century. The current study found that conditions in the south-eastern US will likely become drier overall, given a warmer environment during future winter and spring seasons. This study examined the potential effects of a warmer climate in the 21st century on relevant meteorological fire parameters (e.g. total and convective precipitation, 500-hPa geopotential heights, near-surface relative humidity) and popular fire indices (e.g. Haines and Keetch-Byram Drought Indices) in the south-eastern US. Although the results offered conflicting implications in portions of the study domain, the southern half of the south-eastern US (including the Deep South, the southern Piedmont and Florida) exhibited the highest potential for increasing fire activity in the mid-21st century, given maximum warming and drying in these areas, especially in the spring season.

In this study, we compared various modifications of three common sampling methods (planar intercept, fixed-area microplot and photoload) for estimating fine woody surface fuel components (1-, 10-, 100-h fuels) using artificial fuelbeds of known fuel loadings as reference. Two modifications of the sampling methods were used: (1) measuring diameters only and both diameters and lengths and (2) measuring diameters to (a) the nearest 1.0mm, (b) traditional size classes (1h=0-6mm, 10h=6-25mm, 100h=25-76mm), (c) 1-cm diameter classes and (d) 2-cm classes. We statistically compared differences in sampled biomass values to the reference loading and found that (1) fixed-area microplot techniques were slightly more accurate than the others, (2) the most accurate loading estimates were when fuel particle diameters were measured and not estimated to a diameter class, (3) measuring particle lengths did not improve estimation accuracy, (4) photoload methods performed poorly under high fuel loads and (5) accurate estimate of fuel biomass requires intensive sampling for both planar intercept and fixed-area microplot methods.

Our objective was to contrast stand structure and surface fuel loadings on treated and untreated sites within the 2002 Rodeo-Chediski Fire area. Data from 140 plots on seven paired treated-untreated sites indicated that pre-wildfire treatments reduced fire severity compared with untreated sites. In 2011, coarse woody debris loading (woody material>7.62cm in diameter) was 257% higher and fine woody debris (woody material<7.62cm) was 152% higher on untreated sites than on treated sites. Yet, in spite of higher levels of coarse woody debris on untreated sites, loadings did not exceed recommended ranges based on published literature and many treated sites fell below recommendations. By 2011, basal area and stand density on treated sites and stand density on untreated sites met management guidelines for ponderosa pine forests, but untreated sites had basal areas well below recommendations. Snags declined over this period and only three plots had snags that met minimum size and density requirements for wildlife habitat by 2011. The effects of pre-wildfire treatments are long-lasting and contribute to changes in both overstorey and understorey fuel complexes.

However, it is a challenging task for forest managers to prioritise where, when and how to implement fuel treatments across a large forest landscape. In this study, an optimisation model was developed for long-term fuel management decisions at a landscape scale. Using a simulated annealing algorithm, the model optimises locations and timing of fuel treatments, while considering changes in forest dynamics over time, fire behaviour and spread, values at risk, and operational feasibility. The model employs the Minimum Travel Time algorithm in FlamMap and the Fire and Fuels Extension to the Forest Vegetation Simulator to assess spatial and temporal effects with and without fuel treatments. The objective function is set to minimise total expected loss from a landscape due to wildfires throughout the planning horizon. The model was applied to a 14000-ha study landscape located on the west side of the Bitterroot Valley in Montana. Comparisons between the optimised and random solutions show that the model was able to strategically locate and schedule fuel treatments to efficiently reduce expected loss from the landscape.

In case studies conducted in four USA communities with Community Wildfire Protection Plans in place when wildfires occurred, we saw a range of Community Wildfire Protection Plan projects designed to change the path and intensity of the wildfires. In most of our communities, the Community Wildfire Protection Plan and planning process improved relationships among firefighting agencies, clarified responsibilities and improved communication systems, contributing to fire response efficiency and effectiveness. We found that social learning resulting from the wildfire experience motivated communities to revisit and implement their Community Wildfire Protection Plans, changing the planning frame and scale and increasing the plan's relevance for response and recovery. We conclude that Community Wildfire Protection Plans and experience with wildfire can also result in greater community capacity that builds resilience and increases adaptive capacity for future environmental changes and disasters.

Single channel luminescent O-2-quenched optrodes have been available for use in laboratory and field experiments since the early 2000's. However, to collect the large datasets needed to understand O-2 transport in complex systems, many experiments require a multiple channel O-2 sensor system. This research reports the development of a multiplexing fiber optic O-2 microsensor system designed to conduct high temporal resolution experiments for field studies of plant physiology. The 10 channel system was demonstrated for measuring O-2 concentration in developing soybean seeds (Glycine max L. Merr.) within a climate controlled greenhouse. C1 [Chaturvedi, P.; McLamore, E.

TI USING REMOTE SENSING AND SOIL PHYSICAL PROPERTIES FOR PREDICTING THE SPATIAL DISTRIBUTION OF COTTON LINT YIELD SO TURKISH JOURNAL OF FIELD CROPS LA English DT Article DE Alluvial soils; Degree days; Precision agriculture; Soil texture; Volumetric water content ID CANOPY REFLECTANCE; VEGETATION INDEXES; GROWTH; WATER; MAIZE; NDVI AB This field crop research study addresses the potential of image based remote sensing to provide spatially and temporally distributed information on timely basis for site-specific cotton crop management. Universal applicability of site specific crop management is hampered by lack of timely distributed and economically feasible information on soils and crop conditions in the field and their interaction. The objectives of this study were to demonstrate (1) how site-specific lint yield and associated soil physical properties in a cotton (Gossypium hirsutum L) production field are related to changes in NDVI across the growing season, and (2) when multispectral images should be collected to optimize the cost and efficiency of remote sensing as a tool for site-specific management of the cotton crop. Temporal multispectral images data acquired comprised 10 dates (1998) and 17 dates (1999) during growing seasons, respectively with analysis focused on 24 areas of interest (AOI) (each 2 x 8 m) located in two transects on a 162-ha farm field. Along each transect, soil textural classification ranged from sandy loam to silt loam. At an early growth stage [similar to 300-600 degree days (DDs) after emergence], low NDVI and plant density were associated with soils having low saturated hydraulic conductivity (k(s)) and characterized as drainage ways. Among the AOI's, maximal NDVI was reached at approximately 1565 DD in 1998 and 1350 DD in 1999. A strong range of Pearson correlation (r(2)=0.65 - 0.83) between lint yield and NDVI during flowering stage (similar to 800-1500 DDs) supports the utility of NDVI maps for site-specific application. However, values for NDVI did not correlate well with lint yields beyond 1500 DDs [fruit (boll) opening stage] and decreased sharply on sites with sandy soil texture. Visual separation of seasonal trends in the NDVI vs. DD relationship was also related to sandy soil vs. silt loam soil texture and seasonal rainfall difference between years. Based on the statistical relationship between NDVI vs. DD it was concluded that acquisition of a single imagery during peak bloom period would be sufficient for predicting the spatial distribution of lint yield and will also be economically feasible. Results of this study indicate that spatial variability in soil physical properties induced variability in crop growth and yield. Similar methodology could be adopted for site-specific management of other crops. C1 [Iqbal, Javed] Natl Univ Sci & Technol, Sch Civil & Environm Engn, Inst Geog Informat Syst, Islamabad, Pakistan.

TI Multiscale assessment of green leaf cover in a semi-arid rangeland with a small unmanned aerial vehicle SO INTERNATIONAL JOURNAL OF REMOTE SENSING LA English DT Article ID ATMOSPHERIC CORRECTION; IMAGERY; DEGRADATION; ECOSYSTEMS; MANAGEMENT; SCALE; AREA AB Spatial variability in green leaf cover of a semi-arid rangeland was studied by comparing field measurements on 50 m crossed transects to aerial and satellite imagery. The normalized difference vegetation index was calculated for 2 cm resolution images collected with a multispectral digital camera mounted on a radio-controlled helicopter, as well as a 30 m resolution Landsat Thematic Mapper image. Variograms of green cover from these two sources show that the range of influence for spatial autocorrelation extended to a distance of approximately 200 m. Field transects that are much smaller than the extent of this spatial autocorrelation are more likely to fall within local deviations from the mean landscape condition. A sampling scheme that exceeds the spatial scale of these localized deviations is shown to reduce sample variance and require fewer sampling locations to reach a given level of measurement uncertainty. The time and cost of more spatially extensive sampling at each location may be less than deploying to a larger number of locations with smaller transects, and unmanned aerial vehicles may be a valuable tool in extending current field sampling strategies for quantifying the health of shrub-dominated rangelands.

While there has been much research on mold and decay fungi in wood buildings, it is often overlooked that wet wood is corrosive to the metal screws or nails used to fasten it. Currently, corrosion design in Standard 160 is based upon relative humidity criteria that were developed for atmospheric corrosion. However, the corrosion of metals embedded with wood is controlled by wood chemistry and moisture content rather than atmospheric relative humidity. This paper highlights recent research on the corrosion of metals in wood that may be of interest to those in the building moisture design community who develop codes, standards, and hygrothermal models to minimize the results of structure problems caused by fastener corrosion. The major design implications are that (1) corrosion of metals in wood is not the same as atmospheric corrosion, and (2) that the wood moisture content should be kept below 18%.

Periodically, hurricanes traverse the islands causing changes in structure, species composition, and dynamics of forests. The chronology of post-hurricane vegetation change from 1946 to 2010 on a 0.4 ha ridge plot 380 m in elevation in the Luquillo Experimental Forest of northeastern Puerto Rico showed: (1) defoliation, breakage, and uprooting by wind accompanied by immediate mortality resulting in a loss in forest structure, including stem numbers, tree height, and biomass; (2) delayed mortality of some impacted trees, along with prompt, abundant ingrowth of Cecropia schreberiana, and other secondary species, increasing the number of stems within the forest; (3) a post-hurricane increase in diameter growth and biomass accumulation for similar to 20 years, followed by a decline in both rates; (4) a high post-hurricane survival and increase in dbh increment of Dacryodes excelsa; (5) a post-hurricane increase in species richness for similar to 20 years when primary and secondary species grow together, followed by a decline due to competition; (6) asymptotic conditions for stems, biomass, and number of species after more than 40 years. In addition, related studies in the same forest type showed that hurricanes and thinning evoke comparable growth responses. This study should be of regional interest because Puerto Rico's lower montane rain forest shares similar environmental conditions as well as tree species with the mountainous Antilles.

TI An assessment of alternative cotton fibre quality attributes and their relationship with yarn strength SO CROP & PASTURE SCIENCE LA English DT Article ID FINENESS DISTRIBUTION; IMAGE-ANALYSIS; SINGLE-FIBER; MATURITY; TENACITY; PERFORMANCE; INSTRUMENT; PARAMETERS; ANALYZER; BUNDLE AB Knowing the yarn-strength performance potential of cotton fibre is advantageous to spinners during mill preparation, and to researchers developing new genotypes and management strategies to produce better fibre. Standard High Volume Instrument (HVI) fibre quality attributes include micronaire (a combined measure of fibre linear density and maturity) and bundle tensile properties. While these attributes relate well to yarn strength, alternative fibre quality attributes may better explain the variation in yarn strength. Two field experiments over two seasons were conducted to assess the fibre and yarn performance of some Australian cotton genotypes. The aim was to assess and compare alternative measures for micronaire, and to compare bundle and single-fibre tensile measurements, and assess the relative yarn-strength predictive performance of these attributes. Specific fibre measurement comparisons were for linear density (double-compression Fineness Maturity Tester (FMT) and gravimetric), maturity ratio (FMT, polarised light, calculated, and cross-sectional), and tensile properties (HVI bundle and Favimat Robot single fibre). Multiple linear regression models for yarn strength that included yarn manufacturing variables and standard HVI fibre quality parameters performed well (standard error of prediction (SEP) 2.40cNtex(-1)). Multiple linear regression models performed better when alternatives to micronaire were used, e.g. using gravimetric linear density (SEP, 2.15cNtex(-1)) or laser photometric determined ribbon width (SEP 1.71cNtex(-1)). Yarn strength models were also better when single fibre tensile properties were substituted for bundle tensile properties (SEP 1.07cNtex(-1)). The substitution of alternative fineness variables for micronaire or single-fibre strength for bundle strength in a simple fibre quality index also improved the prediction of yarn strength.

Testing and updating models of social-ecological systems can inform management decisions and, ultimately, improve resilience. We report on the outcomes of a six-year, multidisciplinary model development process in the sagebrush steppe, USA. We focused on creating state-and-transition models (STMs), conceptual models of ecosystem change that represent nonlinear dynamics and are being adopted worldwide as tools for managing ecosystems. STM development occurred in four steps with four distinct sets of models: (1) local knowledge elicitation using semistructured interviews; (2) ecological data collection using an observational study; (3) model integration using participatory workshops; and (4) model simplification upon review of the literature by a multidisciplinary team. We found that different knowledge types are ultimately complementary. Many of the benefits of the STM-building process flowed from the knowledge integration steps, including improved communication, identification of uncertainties, and production of more broadly credible STMs that can be applied in diverse situations. The STM development process also generated hypotheses about sagebrush steppe dynamics that could be tested by future adaptive management and research. We conclude that multidisciplinary development of STMs has great potential for producing credible, useful tools for managing resilience of social-ecological systems. Based on this experience, we outline a streamlined, participatory STM development process that integrates multiple types of knowledge and incorporates adaptive management.

We review recent archaeological research on novaculite quarries and the movement of toolstone away from outcrops, especially during the Middle and Late Archaic Period (6,100-650 BC). Toolstone procurement was intensive and extensive, as shown through mapping of quarry features at Spanish Diggings, a major quarry at the southeastern end of the Novaculite Uplift. Analysis of tool production debris at the Jones Mill Site on the Ouachita River focuses on identifying heat treatment and biface reduction as people moved novaculite from source to habitation.

This technique, used to characterize carbon deposits on petroleum cracking catalysts, provides information on the oxidative stability of carbonaceous solids, where higher temperature reactivity indicates greater structural order, an important property for biochar applications. Differences between TPO profiles of biochars generated by fast pyrolysis of soy straw, barley straw, switchgrass, bamboo, and various woods demonstrated that the oxidative stabilities of the biochars are dependent on the starting biomass. Biochars from softwood and hardwood feedstocks were also processed by torrefaction and gasification to assess the impact of the thermoprocessing method on the TPO data. Results from these TPO analyses showed that the biochars produced under higher temperature conditions afford biochars that are more oxidation resistant. Biochars produced from pine wood (softwood) were consistently more resistant to oxidation compared to their hardwood counterparts. This exploratory study represents the first application of TPO to biochars. C1 [Jackson, Michael A.] ARS, Renewable Prod Technol Unit, Natl Ctr Agr Utilizat Res, USDA, Peoria, IL 61604 USA.

The results showed that bamboo branches had the highest Klason lignin and ash content, about 26% and 2.75%, respectively. The epidermis layer sample had relatively higher carbohydrate content, while the wax layer sample had the highest hot water and ethanol-toluene extractives and starch content. The results indicated that the bamboo processing residues showed potential for different chemical feedstocks. No significant differences were found in the infrared spectroscopy (FTIR) spectra of the different samples, indicating that the chemical functional groups were the same, despite variation in chemical components between samples. Klason lignin isolated from the residues showed a higher maximum degradation rate temperature (501 degrees C) and wider degradation temperature range (200 to 550 degrees C) than the carbohydrates.

To be competitive, companies had to make changes to their product lines, distribution channels, marketing, and overall business strategies. This study was conducted to describe and analyze the log supply component of the hardwood forest products distribution chain and to investigate changes over the past 5 years. State forestry utilization and marketing specialists were interviewed to gain a regional overview of log distributions systems, followed by a survey that resulted in 57 responses from log distributors/brokers/wholesalers from 24 states. Results indicated that, on average, respondents received the majority of their logs from gatewood purchases, and the majority of logs purchased went directly into the sawmill market. From 2007 to 2011, logs sold to sawmill and veneer markets decreased by 6 and 7 percent, respectively, and logs sold to export markets increased by 30 percent. Respondents indicated that increasing fuel and trucking costs, followed by logger shortages, had the greatest negative impact on business operations. In contrast, increasing log exports had the greatest positive impact. Most respondents indicated that although current economic conditions have affected the way they conduct business, they have been able to find ways to adapt. Services such as providing log delivery, bucking logs to desired lengths, and procuring hard-to-obtain species helped companies in the log business remain competitive.

We compare it with C. pulcher (Colosi, 1921), a poorly known species with which it has been confused. Our study is based on morphological analysis of a large number of specimens, including interceptions on cut-flowers and live plants by federal agricultural inspectors of the United States Department of Agriculture (USDA) and the Department of Homeland Security (DHS), and material from eight museum collections. Genetic diversity within C. confusus, n. sp. and C. pulcher is also analysed based on fragments of cytochrome oxidase I (COI), and 16S rRNA. They are differentiated by reproductive characters and genes studied. In C. confusus, n. sp., the phallus has a deep longitudinal groove from the base, near the retractor muscle, to its distal region, close to the papilla. In C. pulcher, there is an oval to rectangular swelling on the basal region of the phallus. Some important differences between these species are also found in the digitiform gland and bursa copulatrix. We describe, illustrate and discuss the color variation, morphological similarities, diagnostic characters and its variation, habitat and distribution for each species. Genetic diversity within C. confusus, n. sp., and C. pulcher is low. In order to analyze their relationship with C. propinquus (Colosi, 1921) (currently a junior synonym of C. pulcher) and C. lugubris (Colosi, 1921) (type-species of Colosius), fragments of COI, 16S, and 28S rRNA genes are also analyzed in a sample of these species. Colosius confusus, n. sp., is a distinct lineage within the genus Colosius. It is not a sister species of C. pulcher, which has C. propinquus as a sister species, here recognized as valid. Colosius confusus, n. sp., is closer to the clade that includes C. pulcher and C. propinquus than it is to C. lugubris. Based on the phylogenetic reconstruction, C. lugubris is sister to all the other Colosius, although additional studies are required to formally test phylogenetic placements and monophyly of the genus. Associated imports and number of interceptions per year of C. confusus, n. sp., by agricultural inspectors are also presented.

We report on a survey of California wetlands sampled along transects associated with Lassen Volcanic National Park, Lake Tahoe, Yosemite National Park, and Sequoia National Park. Each transect ran from the Pacific coast to the Cascades or Sierra Nevada mountains. Pacific chorus frogs (Pseudacris regilla), water, and sediment were collected from wetlands in 2001 and 2002. Twenty-three pesticides were found in frog, water, or sediment samples. Six contaminants including trifluralin, alpha-endosulfan, chlordanes, and trans-nonachlor were found in adult P regilla. Seventeen contaminants were found in sediments, including endosulfan sulfate, chlordanes, 1-chloro-4[2,2-dichloro-1-(4-chlorophenyl)ethenyl]benzene (4,4'-DDE), and chlorpyrifos. The mean number of chemicals detected per pond in sediments was 2.4 (2.5, standard deviation).

The pathogen engages in a race with host seeds for endosperm resources; the pathogen success is negatively correlated with seed germination speed. We developed a deterministic model to predict pathosystem outcomes (seed death versus seed escape), using seed bank data from 80 sites collected over a 13-year period. The response variable (killed seeds in the spring seed bank) was regressed on multiple predictor variables (pathogen and host densities at seed dispersal, amount and timing of precipitation). Increased mortality was associated with high seed rain, high pathogen density, and low autumn precipitation. On xeric sites, a positive feedback loop between pathogen and host is created by a large carryover seed bank containing secondarily dormant seeds vulnerable to fungal attack and results in higher inoculum loads at seed dispersal the following year.

We report on pathosystem outcomes under manipulated water potential and temperature environments commonly observed within semi-arid environments for dormant and non-dormant seeds. We propose a range of outcomes for infected seeds. During summer, seeds remain dormant and are killed across a range of water potentials. During autumn, seeds survive by rapidly germinating or are killed if radicle emergence is delayed by intermittent hydration. In winter/spring, secondarily dormant seeds can be killed by the fungus. The only likely scenarios where seeds escape death include absence of infection (autumn, spring, or following autumn, germination) or infection in autumn when seeds germinate rapidly.

The fungal pathogen Pyrenophora semeniperda can kill a large fraction of B. tectorum seeds. Outcomes in this pathosystem are often determined by the speed of seed germination. In this paper we extend previous efforts to describe the pathosystem by characterising secondary dormancy acquisition of B. tectorum. In the laboratory approximately 80% of seeds incubated at - 1.0 MPa became dormant. In the field, seeds were placed in the seed bank in late autumn, retrieved monthly and dormancy status determined. The field study confirmed the laboratory results; ungerminated seeds became increasingly dormant. Our data suggest that secondary dormancy is much more likely to occur at xeric sites.

TI Tree height and tropical forest biomass estimation SO BIOGEOSCIENCES LA English DT Article ID ABOVEGROUND BIOMASS; CANOPY-HEIGHT; ALLOMETRIC MODELS; AIRBORNE LIDAR; CARBON STOCKS; AMAZON FOREST; TERRA-FIRME; BRAZIL; EQUATIONS; BALANCE AB Tropical forests account for approximately half of above-ground carbon stored in global vegetation. However, uncertainties in tropical forest carbon stocks remain high because it is costly and laborious to quantify standing carbon stocks. Carbon stocks of tropical forests are determined using allometric relations between tree stem diameter and height and biomass. Previous work has shown that the inclusion of height in biomass allometries, compared to the sole use of diameter, significantly improves biomass estimation accuracy. Here, we evaluate the effect of height measurement error on biomass estimation and we evaluate the accuracy of recently published diameter-height allometries at four areas within the Brazilian Amazon. As no destructive sample of biomass was available at these sites, reference biomass values were based on allometries. We found that the precision of individual tree height measurements ranged from 3 to 20% of total height. This imprecision resulted in a 5-6% uncertainty in biomass when scaled to 1 ha transects. Individual height measurement may be replaced with existing regional and global height allometries. However, we recommend caution when applying these relations. At Tapajos National Forest in the Brazilian state of Para, using the pantropical and regional allometric relations for height resulted in site biomass 21% and 25% less than reference values. At the other three study sites, the pantropical equation resulted in errors of less that 2 %, and the regional allometry produced errors of less than 12 %. As an alternative to measuring all tree heights or to using regional and pantropical relations, we recommend measuring height for a well-distributed sample of about 100 trees per site. Following this methodology, 95% confidence intervals of transect biomass were constrained to within 4.5% on average when compared to reference values. C1 [Hunter, M.

Understanding the relationship between fire behavior and rangeland plant community response will help to improve the use of prescribed fire to achieve management objectives. Fire is an important ecological process in many rangeland ecosystems and can be used as a tool to maintain grassland plant communities and shift community composition. Purple threeawn (Aristida purpurea Nutt.) is a grass native to North America that has poor forage quality and the ability to form near monocultures. Therefore, the identification of tools to reduce purple threeawn abundance is desirable. We assessed the effects of summer and fall prescribed fire on purple threeawn plant basal area, tiller production, and plant mortality one growing season post fire in the northern Great Plains. Thermocouples and portable data loggers were used to measure the maximum temperature, heat duration, and heat dosage that individual purple threeawn plants experienced. Fire reduced basal area and tiller production 59 % and 57 %, respectively. Heat dosage (C-statistic = 0.69) and heat duration (C-statistic = 0.65) were good predictors of purple threeawn mortality. A restrospective analysis showed maximum temperatures were similar for fall and summer fires but heat duration and dosage were 44 % and 21 % greater for summer fires, respectively. Our results indicate that purple threeawn is a fire sensitive species. The ability to predict purple threeawn mortality could enhance the efficacy of prescribed fire as tool to restore purple threeawn and other Aristida-dominated plant communities.

TI Using the Storm Water Management Model to predict urban headwater stream hydrological response to climate and land cover change SO HYDROLOGY AND EARTH SYSTEM SCIENCES LA English DT Article ID MISSISSIPPI RIVER-BASIN; URBANIZATION; IMPACTS; SCENARIOS; RUNOFF; SCALE; IDENTIFICATION; SIMULATIONS; UNCERTAINTY; THRESHOLDS AB Streams are natural features in urban landscapes that can provide ecosystem services for urban residents. However, urban streams are under increasing pressure caused by multiple anthropogenic impacts, including increases in human population and associated impervious surface area, and accelerated climate change. The ability to anticipate these changes and better understand their effects on streams is important for developing and implementing strategies to mitigate potentially negative effects. In this study, stream flow was monitored during April-November (2011 and 2012), and the data were used to apply the Storm Water Management Model (SWMM) for five urban watersheds in central Iowa, USA, representing a gradient of percent impervious surface (IS, ranging from 5.3 to 37.1%). A set of three scenarios was designed to quantify hydrological responses to independent and combined effects of climate change (18% increase in precipitation), and land cover change (absolute increases between 5.2 and 17.1%, based on separate projections of impervious surfaces for the five watersheds) for the year 2040 compared to a current condition simulation. An additional set of three scenarios examined stream response to different distributions of land cover change within a single watershed. Hydrological responses were quantified using three indices: unit-area peak discharge, flashiness (R-B Index; Richards-Baker Index), and runoff ratio. Stream hydrology was strongly affected by watershed percent IS. For the current condition simulation, values for all three indices were five to seven times greater in the most developed watershed compared to the least developed watershed. The climate change scenario caused a 20.8% increase in unit-area peak discharge on average across the five watersheds compared to the current condition simulation. The land cover change scenario resulted in large increases for all three indices: 49.5% for unit-area peak discharge, 39.3% for R-B Index, and 73.9% for runoff ratio, on average, for the five watersheds. The combined climate and land cover change scenario resulted in slight increases on average for R-B Index (43.7%) and runoff ratio (74.5%) compared to the land cover change scenario, and a substantial increase, on average, in unit area peak discharge (80.1%). The scenarios for different distributions of land cover change within one watershed resulted in changes for all three indices, with an 18.4% increase in unit-area peak discharge for the midstream scenario, and 17.5% (downstream) and 18.1% (midstream) increases in R - B Index, indicating sensitivity to the location of potential additions of IS within a watershed. Given the likelihood of increased precipitation in the future, land use planning and policy tools that limit expansion of impervious surfaces (e. g. by substituting pervious surfaces) or mitigate against their impacts (e. g. by installing bioswales) could be used to minimize negative effects on streams.

This paper based on the Fisher's discriminant analysis using the fixed-size moving window evolving factor analysis to find characteristic spectra through analyzing the near infrared spectroscopy of Xihu Longjing Tea and Zhejiang Longjing Tea. The Fisher's discriminant analysis was used to reduce the data dimension combined with the principal component analysis. A discrimination model was set up for the identification of the Xihu Longjing Tea and Zhejiang Longjing Tea. The model's accuracy is 97.3%. The results proved that this model is feasible to identify the differences between the Xihu Longjing Tea and Zhejiang Longjing Tea. Unlike other methods, the tea does not need to be made into a powder. It also lays out a theoretical foundation for developing an identification instrument for Xihu Longjing Tea.

The lack of such a list is one of the greatest impediments to protecting the full complement of the world's plant species, and work to achieve this has been slow. An efficient system for identifying those species that are at risk of extinction could help to achieve this goal in a timeframe sensitive to today's conservation needs. Two systems that efficiently use available data to assess conservation status were tested against a provisional International Union for Conservation of Nature and Natural Resources (IUCN) Red List analysis to evaluate the native seed plant species of Puerto Rico. It was demonstrated that both systems efficiently identify species at risk, which is a step toward both the GSPC Target 2 and a more comprehensive IUCN Red List for plants. Both systems were effective at identifying plant species at risk, with the New York analysis identifying 98% and the Smithsonian analysis 85% of the plant species considered Threatened in the IUCN Red List. Both analyses to some extent overestimated those plants at risk, but the species identified are all range restricted and, thus, of some conservation interest.

For farmed species, genomic sequence information will facilitate the selection of animals optimised to live, and be productive, in particular environments. The availability of cattle genome sequence has allowed the breeding industry to take the first steps towards predicting phenotypes from genotypes by estimating a "genomic breeding value" (gEBV) for bulls using genome-wide DNA markers. The sequencing of the buffalo genome and creation of a panel of DNA markers has created the opportunity to apply molecular selection approaches for this species. The genomes of several buffalo of different breeds were sequenced and aligned with the bovine genome, which facilitated the identification of millions of sequence variants in the buffalo genomes. Based on frequencies of variants within and among buffalo breeds, and their distribution across the genome compared with the bovine genome, 90,000 putative single nucleotide polymorphisms (SNP) were selected to create an Axiom (R) Buffalo Genotyping Array 90K. This "SNP Chip" was tested in buffalo populations from Italy and Brazil and found to have at least 75% high quality and polymorphic markers in these populations. The 90K SNP chip was then used to investigate the structure of buffalo populations, and to localise the variations having a major effect on milk production.

TI Phylogenetic Diversity of the Enteric Pathogen Salmonella enterica subsp enterica Inferred from Genome-Wide Reference-Free SNP Characters SO GENOME BIOLOGY AND EVOLUTION LA English DT Article DE H antigens; serovar; O antigens; CRISPR; lineage-through-time plot; comparative method ID ESCHERICHIA-COLI STRAINS; MULTILOCUS GENOTYPE DATA; POPULATION-STRUCTURE; HOST ADAPTATION; EVOLUTION; PARATYPHI; DIVERGENCE; INFERENCE; SEROVARS; LINEAGE AB The enteric pathogen Salmonella enterica is one of the leading causes of foodborne illness in the world. The species is extremely diverse, containing more than 2,500 named serovars that are designated for their unique antigen characters and pathogenicity profiles-some are known to be virulent pathogens, while others are not. Questions regarding the evolution of pathogenicity, significance of antigen characters, diversity of clustered regularly interspaced short palindromic repeat (CRISPR) loci, among others, will remain elusive until a strong evolutionary framework is established. We present the first large-scale S. enterica subsp. enterica phylogeny inferred from a new reference-free k-mer approach of gathering single nucleotide polymorphisms (SNPs) from whole genomes. The phylogeny of 156 isolates representing 78 serovars (102 were newly sequenced) reveals two major lineages, each with many strongly supported sublineages. One of these lineages is the S. Typhi group; well nested within the phylogeny. Lineage-through-time analyses suggest there have been two instances of accelerated rates of diversification within the subspecies. We also found that antigen characters and CRISPR loci reveal different evolutionary patterns than that of the phylogeny, suggesting that a horizontal gene transfer or possibly a shared environmental acquisition might have influenced the present character distribution. Our study also shows the ability to extract reference-free SNPs from a large set of genomes and then to use these SNPs for phylogenetic reconstruction. This automated, annotation-free approach is an important step forward for bacterial disease tracking and in efficiently elucidating the evolutionary history of highly clonal organisms.

A distinct phenotype of this clone is its ability to induce bacteremia and abortion. To facilitate understanding the pathogenesis of this hypervirulent clone, we analyzed a clinical isolate (IA3902) of clone SA using multi-omics approaches. The genome of IA3902 contains a circular chromosome of 1,635,045 bp and a circular plasmid of 37,174 bp. Comparative genomic analysis revealed that IA3902 is most closely related to C. jejuni NCTC11168, which is a reference strain and was previously shown to be non-abortifacient in pregnant animals. Despite the high genomic synteny and sequence homology, there are 12 variable regions (VRs) and 8,696 single-nucleotide polymorphisms and indels between the two genomes. Notably, the variable genes in the capsular polysaccharides biosynthesis and O-linked glycosylation loci of IA3902 are highly homogenous to their counterparts in C. jejuni subsp. doylei and C. jejuni G1, which are known to be frequently associated with bacteremia. Transcriptomic and proteomic profiles were conducted to compare IA3902 with NCTC11168, which revealed that the pathways of energy generation, motility, and serine utilization were significantly up-regulated in IA3902, whereas the pathways of iron uptake and proline, glutamate, aspartate, and lactate utilization were significantly down-regulated. These results suggest that C. jejuni clone SA has evolved distinct genomic content and gene expression patterns that modulate surface polysacharide structures, motilitiy, and metabolic pathways. These changes may have contributed to its hyper-virulence in abortion induction.

It is characterized by widely-spaced oak trees (mostly Quercus Ilex L.), combined with crops, pasture and shrubs in the sub-canopy region. The estimation of the ecosystem evapotranspiration (ET) using remote sensing may assist the monitoring of its state from local to regional scales, improving the management and the conservation of the ecosystem. Thermal-based energy balance techniques which distinguish soil/substrate and vegetation contributions to the radiative temperature and radiation/turbulent fluxes have proven to be reliable in the estimation of the energy surface fluxes, and therefore in the estimation of ET. In particular, the two-source energy balance (TSEB) model of Norman et al. ([3]) and Kustas and Norman ([4]) has shown to be robust for semi-arid sparse canopy-cover landscapes. With the objective of evaluating the model over this environment, an energy flux measurement system has been used. It was installed in a dehesa located in Southern Spain (38 degrees 12' N; 4 degrees 17' W, 736 m a.s.l) with 1 km homogeneous fetch in wind direction. The quality of the measured data fluxes has been tested with the energy-balance closure criterion ([5] [6]) yielding an average closure of 86% which is within the error range found in similar studies. The TSEB model was evaluated in the area for 2012 summer season, using images from MODIS (Moderate Resolution Imaging Spectroradiometer) sensor and ground measured meteorological data. The half-hourly estimates were compared with the flux tower measurements, obtaining a RMSD between modeled and measured energy fluxes within the closure balance error.

Synthetic seed formation was achieved by releasing the sodium alginate/explant combination into 100 mM calcium chloride (CaCl2 center dot H2O) solution for 30 or 45 min. Both control and encapsulated shoots were transferred into sterile Petri dishes and stored at 4 degrees C or 22 degrees C for 0, 2, 4, 6, or 8 weeks. Conversion of synthetic seeds into plantlets for both storage environments was assessed in MS medium or peat-based substrate. No significant difference was found between the 30 and 45 min CaCl2 center dot H2O treatments or the two cultivars. Encapsulation of explants improved survival rate over time irrespective of the medium type or storage environment. Survival rates of 88, 53, 28, and 11% for encapsulated microshoots versus 73, 13, 0, and 0% for control explants were achieved in microshoots stored for 2, 4, 6, and 8 weeks, respectively. The best results were obtained when synthetic seeds were stored at 4 degrees C and germinated on MS medium. Regenerated plantlets were successfully established in potting soil.

Factors studied include lime particle size, mixing time, and overall lime contact time. The study results suggest that coarse lime may be more active than fine lime due to less interaction with surrounding air. Both TCS and TCC concentrations were lower in coarse limed samples versus unlimed samples and the decrease was a function of time. A similar, but statistically insignificant trend in TCC and TCS levels was observed in fine lime samples with respect to unlimed samples. Liming was also found to decrease apparent E1 levels, with more notable decreases in samples amended with coarse lime. P-levels significantly increased after 1-day of contact time, stabilizing over the next 14 days of the study period. This increase and stabilization of P-levels was attributed to the pH and moisture-driven conversion of more chemically complex steroids into P.

TI Reducing assembly complexity of microbial genomes with single-molecule sequencing SO GENOME BIOLOGY LA English DT Article ID PROKARYOTIC GENOMES; BACTERIAL GENOMES; READS; DNA; POLYMERASE; CHALLENGES; OUTBREAK; PROJECTS; STRAIN; GAUGE AB Background: The short reads output by first-and second-generation DNA sequencing instruments cannot completely reconstruct microbial chromosomes. Therefore, most genomes have been left unfinished due to the significant resources required to manually close gaps in draft assemblies. Third-generation, single-molecule sequencing addresses this problem by greatly increasing sequencing read length, which simplifies the assembly problem. Results: To measure the benefit of single-molecule sequencing on microbial genome assembly, we sequenced and assembled the genomes of six bacteria and analyzed the repeat complexity of 2,267 complete bacteria and archaea. Our results indicate that the majority of known bacterial and archaeal genomes can be assembled without gaps, at finished-grade quality, using a single PacBio RS sequencing library. These single-library assemblies are also more accurate than typical short-read assemblies and hybrid assemblies of short and long reads. Conclusions: Automated assembly of long, single-molecule sequencing data reduces the cost of microbial finishing to $1,000 for most genomes, and future advances in this technology are expected to drive the cost lower. This is expected to increase the number of completed genomes, improve the quality of microbial genome databases, and enable high-fidelity, population-scale studies of pan-genomes and chromosomal organization.

TI The genome sequence of the most widely cultivated cacao type and its use to identify candidate genes regulating pod color SO GENOME BIOLOGY LA English DT Article DE Theobroma cacao L.; genome; Matina 1-6; haplotype phasing; genetic mapping; pod color; MYB113 ID HIDDEN MARKOV-MODELS; VITIS-VINIFERA L.; THEOBROMA-CACAO; TRANSPOSABLE ELEMENTS; LTR RETROTRANSPOSONS; ARABIDOPSIS-THALIANA; MAXIMUM-LIKELIHOOD; FLOW-CYTOMETRY; DNA-CONTENT; PLANT AB Background: Theobroma cacao L. cultivar Matina 1-6 belongs to the most cultivated cacao type. The availability of its genome sequence and methods for identifying genes responsible for important cacao traits will aid cacao researchers and breeders. Results: We describe the sequencing and assembly of the genome of Theobroma cacao L. cultivar Matina 1-6. The genome of the Matina 1-6 cultivar is 445 Mbp, which is significantly larger than a sequenced Criollo cultivar, and more typical of other cultivars. The chromosome-scale assembly, version 1.1, contains 711 scaffolds covering 346.0 Mbp, with a contig N50 of 84.4 kbp, a scaffold N50 of 34.4 Mbp, and an evidence-based gene set of 29,408 loci. Version 1.1 has 10x the scaffold N50 and 4x the contig N50 as Criollo, and includes 111 Mb more anchored sequence. The version 1.1 assembly has 4.4% gap sequence, while Criollo has 10.9%. Through a combination of haplotype, association mapping and gene expression analyses, we leverage this robust reference genome to identify a promising candidate gene responsible for pod color variation. We demonstrate that green/red pod color in cacao is likely regulated by the R2R3 MYB transcription factor TcMYB113, homologs of which determine pigmentation in Rosaceae, Solanaceae, and Brassicaceae. One SNP within the target site for a highly conserved trans-acting siRNA in dicots, found within TcMYB113, seems to affect transcript levels of this gene and therefore pod color variation. Conclusions: We report a high-quality sequence and annotation of Theobroma cacao L. and demonstrate its utility in identifying candidate genes regulating traits.

All propagative stages of the nematode were present in larval galleries of a bark beetle, Trypophloeus populi. The dauer juveniles occupy the haemocoel of older larvae, pupae and adult beetles. The characteristic morphology of the male spicules with small but distinct cucullus, extended anterior vulval lip in female, lateral fields with four incisures, and number and arrangement of male caudal papillae, indicate that B. masseyi sp. n. is closely related to the xylophilus group. This relation has been confirmed by DNA sequencing and phylogenetic analysis of the 28S rDNA region. The new species is characterised by the body length of 958 (765-1203) mu m in female and 874 (691-1122) mu m in male, moderately slender body (a = 38.2 (33.5-41.1) and 38.0 (33.1-44.1) in female and male, respectively), and spicules 29.2 (26.2-34.7) mu m long with a small cucullus (1.3-1.5 mu m in diam.) at their tips. Bursaphelenchus masseyi sp. n. can be separated from other species in the xylophilus group by the morphology of spicules which have a short capitulum and unique rostrum that is pointed somewhat anteriorly, relatively thick vulval flap, which is straight, parallel to the body long axis and bent towards the body wall at its distal end, and other morphological and morphometric characters. The new species most closely resembles B. trypophloei, but differs by the morphology of spicules (short but distinct condylus vs condylus in a continuous line with dorsal lamina, and smaller cucullus). The taxonomic separation of the new species is also confirmed by the unique molecular profile of the ITS region (ITS-RFLP). Diallelic cross-breeding in vitro revealed also that B. masseyi sp. n. and B. trypophloei are reproductively incompatible. The new species showed poor ability to develop and reproduce on Botrytis cinerea cultures, although it grew vigorously on laboratory cultures of Polish and Colorado isolates of Cytospora chrysosperma, the fungus naturally associated with galleries of the nematode vector, T. populi.

TI Evaluating the agreement between measurements and models of net ecosystem exchange at different times and timescales using wavelet coherence: an example using data from the North American Carbon Program Site-Level Interim Synthesis SO BIOGEOSCIENCES LA English DT Article ID GLOBAL VEGETATION MODEL; DIOXIDE EXCHANGE; BOREAL FORESTS; INTERANNUAL VARIABILITY; PRIMARY PRODUCTIVITY; ATMOSPHERE EXCHANGE; MULTISCALE ANALYSIS; CANOPY NITROGEN; CO2; TEMPERATE AB Earth system processes exhibit complex patterns across time, as do the models that seek to replicate these processes. Model output may or may not be significantly related to observations at different times and on different frequencies. Conventional model diagnostics provide an aggregate view of model-data agreement, but usually do not identify the time and frequency patterns of model-data disagreement, leaving unclear the steps required to improve model response to environmental drivers that vary on characteristic frequencies. Wavelet coherence can quantify the times and timescales at which two time series, for example time series of models and measurements, are significantly different. We applied wavelet coherence to interpret the predictions of 20 ecosystem models from the North American Carbon Program (NACP) Site-Level Interim Synthesis when confronted with eddy-covariance-measured net ecosystem exchange (NEE) from 10 ecosystems with multiple years of available data. Models were grouped into classes with similar approaches for incorporating phenology, the calculation of NEE, the inclusion of foliar nitrogen (N), and the use of model-data fusion. Models with prescribed, rather than prognostic, phenology often fit NEE observations better on annual to interannual timescales in grassland, wetland and agricultural ecosystems. Models that calculated NEE as net primary productivity (NPP) minus heterotrophic respiration (HR) rather than gross ecosystem productivity (GPP) minus ecosystem respiration (ER) fit better on annual timescales in grassland and wetland ecosystems, but models that calculated NEE as GPP minus ER were superior on monthly to seasonal timescales in two coniferous forests. Models that incorporated foliar nitrogen (N) data were successful at capturing NEE variability on interannual (multiple year) timescales at Howland Forest, Maine. The model that employed a model-data fusion approach often, but not always, resulted in improved fit to data, suggesting that improving model parameterization is important but not the only step for improving model performance. Combined with previous findings, our results suggest that the mechanisms driving daily and annual NEE variability tend to be correctly simulated, but the magnitude of these fluxes is often erroneous, suggesting that model parameterization must be improved. Few NACP models correctly predicted fluxes on seasonal and interannual timescales where spectral energy in NEE observations tends to be low, but where phenological events, multi-year oscillations in climatological drivers, and ecosystem succession are known to be important for determining ecosystem function. Mechanistic improvements to models must be made to replicate observed NEE variability on seasonal and interannual timescales. C1 [Stoy, P.

In this contribution, we review the way in which KM tools and techniques are used in forest management, and categorize a selected set of them according to their contribution to support decision makers in the phases of problem identification, problem modelling, and problem solving. Material and methods: Existing examples of cognitive mapping tools, web portals, workflow systems, best practices, and expert systems as well as intelligent agents are screened for their applicability and use in the context of decision support for sustainable forest management. Evidence from scientific literature and case studies is utilized to evaluate the contribution of the different KM tools to support problem identification, problem modelling, and problem solving. Main results: Intelligent agents, expert systems and cognitive maps support all phases of the forest planning process strongly. Web based tools have good potential to support participatory forest planning. Based on the needs of forest management decision support and the thus-far underutilized capabilities of KM tools it becomes evident that future decision analysis will have to consider the use of KM more intensively. Research highlights: As the problem-solving process is the vehicle for connecting both knowledge and decision making performance, the next generation of DSS will need to better encapsulate practices that enhance and promote knowledge management. Web based tools will substitute desktop applications by utilizing various model libraries on the internet.

TI Comparisons of Amylolytic Enzyme Activities and beta-Amylases with Differing Bmy1 Intron III Alleles to Osmolyte Concentration and Malt Extract luring Congress Mashing with North American Barley Cultivars SO JOURNAL OF THE AMERICAN SOCIETY OF BREWING CHEMISTS LA English DT Article DE alpha-Amylase; beta-Amylase; Limit dextrinase; Malt extract; Mashing; Osmolyte concentration ID PISUM-SATIVUM-L; ALPHA-AMYLASE; LIMIT DEXTRINASE; DIASTATIC POWER; SUGAR CONCENTRATIONS; QUALITY MEASUREMENTS; GERMINATING BARLEY; STARCH DEGRADATION; DEBRANCHING ENZYME; GLUCOSIDASE AB This study was conducted to determine the relationships between patterns of activity of malt amylolytic enzymes (alpha-amylase, beta-amylase, and limit dextrinase) and the patterns of osmolyte concentration (OC) and malt extract (ME) production in two- and six-row North American barley cultivars over the course of Congress mashing and to test three hypotheses: 1) that maximal activity of and rates of increase in beta-amylase activity during the initial phases of mashing would correlate better than the other amylolytic enzymes with OC and ME production, 2) that positive rates of change of OC would continue for a longer period than ME during mashing regardless of cultivar beta-amylase intron EU allelic variation, and 3) that beta-amylase intron III allelic variation would have no significant association with the magnitude or OC and ME production during mashing. Malts of 12 barley cultivars were mashed in a micromasher and assayed for amylolytic enzyme activities and OC and ME levels at six time points during the 115-min Congress mashing regime. Maximal beta-amylase activity correlated positively and significantly with OC (r = 0.701, P = 0.011) and better than with ME (r = 0.419, P = 0.175). Maximal alpha-amylase activity correlated positively and significantly with OC (r = 0.582, P = 0.047) but not as well as did beta-amylase, nor did it significantly correlate with ME. Maximal limit dextrinase activity did not correlate significantly with either OC or ME. Rates of increase of beta-amylase activity correlated well with rates of increase of OC (r = 0.656, P = 0.0205) but not with ME (r = 0.269. P = 0.398) during the initial phase of mashing (5 to 30 min). Rates of increase of alpha-amylase and limit dextrinase activities did not correlate significantly with OC or ME over this period. Rates of increase for wort OC and ME for each cultivar were greatest over the period from 5 to 30 min of mashing. Between 55 and 75 min, rates of increase of wort ME plummeted to near nil and remained significantly the same (P < 0.0001) for the remainder of mashing. In contrast, rates of increase in wort OC for each cultivar were still positive between 55 and 75 min, albeit at a lower level than earlier in mashing. For most cultivars, rates of increase in OC, although decreasing, remained positive until the end of mashing. beta-Amylase intron III allelic variation had no apparent association with this pattern of OC change. The OC data indicate continued degradation of storage compounds for a significantly longer duration than increases in ME after the mass of material in wort had stabilized. Throughout mashing, cultivars with either the beta-amylase Bmy1.a or Bmy1.b intron III alleles were not significantly different for the highest OC or ME. OC measurements resulted in more significant differences between cultivars than ME measurements. Also, OC did not consistently rank cultivars in the same pattern as ME during mashing, indicating that the intrinsic differences in the two methods yield slightly differing results. These data support all three hypotheses. C1 [Duke, Stanley H.; Henson, Cynthia A.] Univ Wisconsin, Dept Agron, Madison, WI 53706 USA. [Vinje, Marcus A.] USDA ARS, CCRU, Madison, WI USA.

TI Determinants of household participation in the management of rural water supply systems: A case from Ethiopia SO WATER POLICY LA English DT Article DE Community participation; Ethiopia; Rural water supply; Water management; Water supply sustainability ID SUSTAINABILITY; SERVICES AB Access to safe drinking water supply in Ethiopia is among the lowest in sub-Saharan Africa. While both governmental and non-governmental organizations have implemented water supply projects in recent years, many fail shortly after construction due to improper management. In this paper, we examine socio-economic, institutional and exogenous factors affecting household participation in the management of water supply systems for drinking purposes. A survey was carried out involving 16 water supply systems and 160 households within the Achefer area, in the Amhara region, Ethiopia. The results show that household contributions to water supply system management are positively and significantly affected by user participation during the project design and implementation, by advocacy provided by the project and by greater household income. Thus, for drinking water systems in rural areas to be sustainable, these factors should be included when planning water supply projects.

The suitability of this procedure is demonstrated by using a coplanar waveguide transmission-line sensor to measure the permittivity of five liquids, covering a wide range of complex permittivity. The results agree closely with expected values when the radiation and conductor losses are small. This technique allows the permittivity of materials to be measured without knowing the planar transmission-line dimensions apart from the line lengths.

The chicken meat was stored in a refrigerator for 13 days at 4 degrees C. The changes in dielectric constant and loss factor reflected changes related to water binding, water loss and ionic activity. The dielectric constant decreased with frequency and storage duration with a slope change at about 4 GHz. The frequency dependence of the dielectric loss factor was dominated by the ionic conduction in the lower frequency range and dipolar relaxation of water above 4 GHz. The dielectric loss factor increased with storage duration for frequencies below 4 GHz and remained almost constant above that. For purpose of comparison, the effect of water loss by mechanical extraction on dielectric properties of chicken meat was investigated. The frequency dependence was found to be similar to that observed for the aging with both the dielectric constant and dielectric loss factor decreasing with the water loss at all frequencies. This will be developed further to better understand the dynamic of aging and its effect on the quality of chicken meat C1 ARS, Qual & Safety Assessment Res Unit, USDA, Richard B Russell Agr Res Ctr, Athens, GA 30605 USA.

This disease is worldwide in occurrence and costs the animal agricultural industry many millions of dollars to control. In recent years, the modern tools of molecular biology, biochemistry, cell biology and immunology have been used to expand greatly our knowledge of these parasites and the disease they cause. Such studies are essential if we are to develop new means for the control of coccidiosis. In this chapter, selective aspects of the biology of these organisms, with emphasis on recent research in poultry, are reviewed. Topics considered include taxonomy, systematics, genetics, genomics, transcriptomics, proteomics, transfection, oocyst biogenesis, host cell invasion, immunobiology, diagnostics and control.

Chemical derivatization of the lipid A was not needed, and the SFC-MS/MS analysis only took 2 min per injection. The method was evaluated by analyzing lipid A spiked into two representative food matrices, lettuce and ground beef. For sample preparation, a simple shaking procedure with 3/1 (v/v) chloroform-methanol was used. % Recoveries in spiked samples were 74 +/- 10 at 10-30 mu g g(-1) in lettuce and 110 +/- 5 in meat at 30 mu g g(-) (1).

Previous research suggested that limitations on fire size can result from the evolution of natural fire regimes, specifically in places where fuels were recently reduced by previous burning. To explore the broader-scale importance of fire management on wilderness landscapes, we selected three study regions representing diverse ecosystems in the western U. S. and modeled the change in fire size distributions across a gradient defined by wilderness/non-wilderness boundaries. For randomly selected locations across the gradient, we derived a scaling parameter (alpha) using fire size-frequency data for public lands (1984-2007); the parameter reflected the magnitude of change in the right tail of the fire size distribution where the largest fires reside. We then used quantile regression to model changes in a across the wilderness gradient, interpreting the results in terms of constraints on the relative role of large fires in structuring the fire size distribution. In the Southwest study region, the influence of large fires on size distributions decreased across the gradient toward wilderness at some places, suggesting that increased occurrence of natural burning, favored by wilderness management, led to limitations on fire sizes within recent timeframes. In contrast, we were unable to support the expectation that wilderness fire management limits the role of large fires in the Sierra Nevada and Northern Rockies study regions. Rather, the predominance of large fires increased toward wilderness interiors. Among spatial climate and topographic roughness variables included in our study, only winter and fire season precipitation limited fire size in the Northern Rockies, whereas several constraints on large fire occurrence operated in other regions. In southwestern ecosystems, evidence is needed to document stability in fire size distributions through time. In ecosystems of the Sierra Nevada and Northern Rockies, a longer temporal extent of observations may better match scales of disturbance and recovery. Our findings reflect the role of wilderness in addressing a fire deficit which has resulted from strong human influences on forests and fires over the past 150 years.

TI Long-term redevelopment of resource islands in shrublands of the Great Basin, USA SO ECOSPHERE LA English DT Article DE Artemisia nova; Artemisia tridentata; coppice dunes; ex-arable fields; islands of fertility; land-use legacies; old fields; soil heterogeneity ID HERBACEOUS VEGETATION HETEROGENEITY; SOIL CHEMICAL-PATTERNS; ARTEMISIA-TRIDENTATA; SAGEBRUSH STEPPE; PLANT-COMMUNITIES; BIG SAGEBRUSH; ECOSYSTEMS; CARBON; DISTURBANCE; MICROSITE AB Soil resource availability in semi-arid and arid shrubland ecosystems is highly heterogeneous and includes patterns of accumulation primarily beneath shrubs as opposed to shrub interspaces. These resource islands contribute to ecosystem resilience after natural disturbances such as fire, yet very little is known regarding their redevelopment following soil disturbance and shrub re-colonization. Cultivation involves the removal of native vegetation and mixing of soils both vertically and horizontally. The old fields in this study offered a unique look at the long-term redevelopment of resource islands under shrubs where cultivation was abandoned nearly a century ago. Using adjacent pairs of previously cultivated and native shrubland from three soil series, we sampled surface soils (0-5 cm) in microsites under shrubs and in the interspaces between them to examine if the soil fertility in old fields (C, N, P, Ca, Mg, K) had regained similar microsite patchiness to the native shrubland, if the values of each soil fertility measure in old fields were different from native shrubland, and if the overall microsite fertility under shrubs in old fields was different from non-disturbed microsites. We found that while most of the resource island patterning had redeveloped, the content of each fertility measure had not recovered to pre-disturbance levels. Further, the recovery was different between the soil series and between sites with different dominant shrub species. There were also differences between sites within the same soil series, suggesting that historical cultivation practices may influence resource island recovery in multiple ways. Overall, under-shrub microsite fertility in previously cultivated areas was distinct from comparable under-shrub microsites in native areas in two out of the three soil series. These findings suggest that while patterning may redevelop within 90 years, it may take over a century for resource island fertility to fully re-establish in some formerly cultivated soils.

Increased water availability can stimulate both plant nitrogen uptake and microbial nitrogen mineralization, but may also stimulate losses from the ecosystem. Here, we assess the effect of water availability on nitrogen stocks and transformations in an arid ecosystem. We conducted a field experiment with five levels of precipitation input (-80%, -50%, ambient, +50%, +80%) and two levels of N fertilization (ambient or 10 g.m(-2).yr(-1) NH4NO3) in a desert grassland of the Chihuahuan Desert. We measured in situ net N mineralization, plant N uptake, foliar N, N leaching under grass-rooting zone, and soil N availability during two years. Our results showed that increased water availability did not affect net N mineralization, but there was higher plant N uptake than with drought. Soil inorganic N pools were 2-4 times lower with increased water availability compared to drought conditions. N leaching below grass-rooting zone was higher in dry than wet conditions because of higher available N. Increased water availability differentially affected N species significantly reducing the NO3:NH4 ratio. The accumulation of inorganic N during drought was the result of a decoupling between microbial and plant activity, and suggests that the cycling of N is more open in dry years than in wet years.

WPC samples from selected formulations were divided into two identical groups. The first group was exposed in exterior conditions in Vancouver, British Columbia, and Hilo, Hawaii, at sun and shadow sites. Water absorption and biological activity were monitored by field inspection, density change measurement, and optical and scanning electron microscopy. The second group was used for soil block culture testing performed according to AWPA E10 (or ASTM D1413). Specimens were conditioned by immersion in water at room and elevated temperatures. Results of fungal decay activity are reported as specimen weight loss or corresponding density decrease. Observed density changes during field exposure and soil block culture testing are compared. Samples exposed to aggressive exterior conditions underwent decay, which was detected by microscopic inspection of board cross sections and calculated density decrease. Fruiting bodies of brown-rot decay fungi (Dacryopinax spathularia) were found on some sample surfaces during field inspections. The decay process of tested materials in the field seemed to require an initiation period dependent on exposure site. The shortest initiation time and the most aggressive environment for decay of WPC samples were found at the sunny site in Hilo. Laboratory soil block culture testing showed weight loss and density decrease of experimental WPCs to depend on conditioning. Correlations between laboratory test results and WPC performance in the field are described. C1 [Ibach, Rebecca E.] USDA Forest Serv, Forest Prod Lab, Madison, WI USA.

Lorenz, Linda TI Protein Modifiers Generally Provide Limited Improvement in Wood Bond Strength of Soy Flour Adhesives SO FOREST PRODUCTS JOURNAL LA English DT Article ID UREA AB Soy flour adhesives using a polyamidoamine-epichlorohydrin (PAE) polymeric coreactant are used increasingly as wood adhesives for interior products. Although these adhesives give good performance, higher bond strength under wet conditions is desirable. Wet strength is important for accelerated tests involving the internal forces generated by the swelling of wood and plasticization of the adhesive with increasing humidity. Soy proteins are globular due to their hydrophobicity; thus, it was expected that adding modifiers to open the protein structure should improve protein-protein and protein-wood interactions to help withstand both internal and external forces applied to the bond. Because modifiers have been shown to improve the performance of soy protein isolate adhesives, use of these modifiers has been examined as a way to improve soy flour adhesives. Protein-disrupting chaotropic agents (urea, guanidine hydrochloride, and dicyandiamide), surfactants (sodium dodecyl sulfate or cetyltrimethylammonium bromide), and the cosolvent propylene glycol were all expected to provide increased protein-protein and protein-PAE interactions. Improved interactions would make the soy flour adhesives durable enough to better pass wet bond strength tests specified for most interior bonded wood products. However, no substantial improvement was seen in cured wood bond strengths in wet conditions for soy flour adhesives by adding any of these modifiers with or without PAE polymer addition. These results led to a proposal that carbohydrates, about 45 percent by weight of soy flour, are interfering with obtaining greater adhesive bond strengths from the protein portion of the flour.

Precipitation anomalies reflect variability in water supply to the land surface, while soil moisture, groundwater and surface water anomalies reflect deficiencies in moisture storage. In contrast, evapotranspiration (ET) anomalies provide unique yet complementary information, reflecting variations in actual water use by crops a useful diagnostic of vegetation health. Here we describe a remotely sensed Evaporative Stress Index (ESI) based on anomalies in actual-to-reference ET ratio. Actual ET is retrieved from thermal remote sensing data using a diagnostic soil-plant-atmosphere modeling system forced by measurements of morning land-surface temperature (LST) rise from geostationary satellites. In comparison with vegetation indices, LST is a relatively fast-response variable, with the potential for providing early warning of crop stress reflected in increasing canopy temperatures. Spatiotemporal patterns in ESI have been compared with patterns in the U. S. Drought Monitor and in standard precipitation-based indices, demonstrating reasonable agreement. However, because ESI does not use precipitation as an input, it provides an independent assessment of evolving drought conditions, and is more portable to data-sparse parts of the world lacking dense rain-gauge and Doppler radar networks. Integrating LST information from geostationary and polar orbiting systems through data fusion, the ESI has unique potential for sensing moisture stress at field scale, with potential benefits to yield estimation and loss compensation efforts. The ESI is routinely produced over the continental U. S. using data from the Geostationary Operational Environmental Satellites, with expansion to North and South America underway. In addition drought and ET monitoring applications are being developed over Africa and Europe using land-surface products from the Meteosat Second Generation (MSG) platform. (C) 2013 The Authors.

This variability at the canopy, field and landscape scale, makes it very challenging for quantifying spatially-distributed surface fluxes. This paper describes a robust but relatively simple thermal-based energy balance model that parameterizes the key soil/substrate and vegetation exchange processes affecting the radiative balance and turbulent energy transport with the overlying atmosphere. The thermal-based model, called the Two-Source Energy Balance (TSEB) model solves for the soil/substrate and canopy temperatures that achieves a balance in the radiation and turbulent heat flux exchange with the lower atmosphere for the soil/substrate and vegetation elements. The TSEB scheme permits interaction between soil/substrate and canopy elements which are both coupled to the atmosphere via the canopy-air temperature; this canopy-air temperature is highly correlated to the aerodynamic surface temperature used in computing surface sensible heat flux. As a result, the TSEB modeling framework is applicable to a wide range of atmospheric and canopy cover conditions. An overview of recent applications of the TSEB modeling framework to a variety of agricultural landscapes is presented. (C) 2013 The Authors. Published by Elsevier B.V.

One of the keys to meeting these demands is maximizing the efficiency of water use in agricultural applications. Toward this end, a thorough understanding of the factors driving evapotranspiration and their response to spatiotemporal variations in local environmental conditions is needed for the development and validation of numerical and remote sensing-based models. Moreover, because these exchange processes are strongly nonlinear, scaling measurements collected at one scale to another remains a nontrivial task. In an effort to identify the key environmental drivers controlling the latent heat flux (lambda E) from agro-ecosystems and their potential impacts on upscaling in-situ flux measurements, eddy covariance and micrometeorological data collected over maize and soy at three distinct sites located in Maryland, Iowa, and Minnesota, respectively were evaluated for the years between 2007 and 2011. The magnitudes of the evaporative fluxes were comparable for measurements collected during clear-sky days with similar environmental conditions; on average, the measurements of lambda E agreed to within 50 W m(-2), or approximately 10%. When considered in terms of evaporative fraction (f(e)), however, there were marked differences among the sites. For example, while the magnitude and diurnal pattern of f(e) for mature maize at the Minnesota site was nearly constant (f(e) = 0.66) during the day, f(e) at both the Maryland and Iowa site increased steadily during the day from a minimum value near 0.68 at midmorning to peak value of 0.87 in the afternoon. These differences appear to be primarily linked to differences in soil moisture and vegetation density at the various sites. As such, this research underscores the impact of local environmental conditions in controlling land-atmosphere exchange processes. It also underscores the importance accurately describing local environmental conditions when modeling surface fluxes. (C) 2013 The Authors. Published by Elsevier B.V.

We sequenced the 158 kb plastome and the 690 kb mitochondrial genome of common milkweed (Asclepias syriaca [Apocynaceae]) and found evidence of intracellular HGT for a 2.4-kb segment of mitochondrial DNA to the rps2-rpoC2 intergenic spacer of the plastome. The transferred region contains an rpl2 pseudogene and is flanked by plastid sequence in the mitochondrial genome, including an rpoC2 pseudogene, which likely provided the mechanism for HGT back to the plastome through double-strand break repair involving homologous recombination. The plastome insertion is restricted to tribe Asclepiadeae of subfamily Asclepiadoideae, whereas the mitochondrial rpoC2 pseudogene is present throughout the subfamily, which confirms that the plastid to mitochondrial HGT event preceded the HGT to the plastome. Although the plastome insertion has been maintained in all lineages of Asclepiadoideae, it shows minimal evidence of transcription in A. syriaca and is likely nonfunctional. Furthermore, we found recent gene conversion of the mitochondrial rpoC2 pseudogene in Asclepias by the plastid gene, which reflects continued interaction of these genomes. C1 [Straub, Shannon C.

These are relatively recent diseases in plant crops, thereby inferring a modern evolutionary trajectory, but no overall hypothesis on their origins has been presented. Plate tectonic movements provide an explanation for the disjunction between modern geographic range and phylogeny. Northern species, on Laurasia, represent both modern European and North American ranges. Southern species, on Gondwana, indicate a further speciation event as ancient India, conjoint with Madagascar, separated from Africa, left Madagascar on its own, and produced the single heat tolerant species while drifting across the equator to its modern position. Phylogeny, epidemiology and geography of the modern species point backwards to a single original speciation event from a free-living form, associated opportunistically with angiosperm and psyllid insect ancestors. The original heat-sensitive species lived in the equatorial but cool climate of the Central Pangaean Mountains probably > 300 Ma. The obligately alternating insect/plant host lifestyle developed opportunistically with the evolution and spread of flowering plants and psyllids. C1 [Nelson, W.

The objective of this study was to identify potential molecular mechanism(s) utilising a candidate-gene approach in five peanut genotypes with contrasting drought responses. An early season drought stress treatment was applied under environmentally controlled rain-out shelters. When water was completely withheld for 3 weeks, no physical differences were observed for treated plants compared with their fully irrigated counterparts as indicated by relative water content; however, yield, grades (total sound mature kernel, TSMK), specific leaf area, and leaf dry matter content showed significant differences. Comparing expression levels of candidate genes, C76-16' exhibited significantly higher levels for CuZnSOD, NsLTP and drought protein 1 week earlier compared to the other genotypes, followed by significantly lower levels for the same genes. This suggested an early recognition of drought in C76-16 followed by an acclimation response. Cultivar Georgia Green' showed different patterns of gene-expression than C76-16. AP-3, a susceptible genotype, showed generally lower levels of gene-expression than C76-16 and Georgia Green. Myo-inositol phosphate synthase gene-expression showed high levels in irrigated treatment, ranging from 4-fold for 08T-12 to 12-fold for Georgia Green, but were significantly inhibited in drought treatment after 2 weeks of drought and after recovery.

However remote sensing instruments trade spatial resolution for swath width and it's difficult to acquire remotely sensed data with both high spatial resolution and frequent coverage. A synthesized approach fusing multiple types of remote sensing imagery provides a feasible and economical solution. In this paper, we demonstrate an operational data fusion framework based on Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM) for integrating existing MODIS data products (daily, 500m) and freely available Landsat data (16-day, 30m). Phenological metrics are extracted from the fused Landsat and MODIS data. Our case study focuses on an agricultural region in central Iowa. Initial results show that the detailed spatial and temporal variability of the landscapes can be identified from the fused remote sensing data. The derived phenology metrics show distinct features for crops and forest at the field scales and can be explained by the USDA's reports on the crop progress. The data fusion and time-series analysis approaches provide a feasible solution to for ecological and crop condition monitoring at the field scales.

TI Understanding the spatial formation and accumulation of fats, oils and grease deposits in the sewer collection system SO WATER SCIENCE AND TECHNOLOGY LA English DT Article DE FOG; hydraulic configurations; pilot-scale sewer collection system; sanitary sewer overflows ID FORMATION MECHANISMS AB Sanitary sewer overflows are caused by the accumulation of insoluble calcium salts of fatty acids, which are formed by the reaction between fats, oils and grease (FOG) and calcium found in wastewaters. Different sewer structural configurations (i.e., manholes, pipes, wet wells), which vary spatially, along with other obstructions (roots intrusion) and pipe deformations (pipe sags), may influence the detrimental buildup of FOG deposits. The purpose of this study was to quantify the spatial variation in FOG deposit formation and accumulation in a pilot-scale sewer collection system. The pilot system contained straight pipes, manholes, roots intrusion, and a pipe sag. Calcium and oil were injected into the system and operated at alkaline (pH = 10) and neutral (pH = 7) pH conditions. Results showed that solid accumulations were slightly higher at neutral pH. Fourier transform infrared (FTIR) analysis on the solids samples confirmed that the solids were indeed calcium-based fatty acid salts. However, the fatty acid profiles of the solids deviated from the profile found from FOG deposits in sewer systems, which were primarily saturated fatty acids. These results confirm the work done previously by researchers and suggest an alternative fate of unsaturated fatty acids that does not lead to their incorporation in FOG deposits in full-scale sewer systems.

TI Spatial patterns in timing of the diurnal temperature cycle SO HYDROLOGY AND EARTH SYSTEM SCIENCES LA English DT Article ID LAND-SURFACE TEMPERATURE; MODEL; ASSIMILATION; PRECIPITATION; CLIMATE; SYSTEM AB This paper investigates the structural difference in timing of the diurnal temperature cycle (DTC) over land resulting from choice of measuring device or model framework. It is shown that the timing can be reliably estimated from temporally sparse observations acquired from a constellation of low Earth-orbiting satellites given record lengths of at least three months. Based on a year of data, the spatial patterns of mean DTC timing are compared between temperature estimates from microwave Ka-band, geostationary thermal infrared (TIR), and numerical weather prediction model output from the Global Modeling and Assimilation Office (GMAO). It is found that the spatial patterns can be explained by vegetation effects, sensing depth differences and more speculatively the orientation of orographic relief features. In absolute terms, the GMAO model puts the peak of the DTC on average at 12:50 local solar time, 23 min before TIR with a peak temperature at 13:13 (both averaged over Africa and Europe). Since TIR is the shallowest observation of the land surface, this small difference represents a structural error that possibly affects the model's ability to assimilate observations that are closely tied to the DTC. The equivalent average timing for Ka-band is 13:44, which is influenced by the effect of increased sensing depth in desert areas. For non-desert areas, the Ka-band observations lag the TIR observations by only 15 min, which is in agreement with their respective theoretical sensing depth. The results of this comparison provide insights into the structural differences between temperature measurements and models, and can be used as a first step to account for these differences in a coherent way.

SO LIDAR REMOTE SENSING FOR ENVIRONMENTAL MONITORING SE Proceedings of SPIE LA English DT Proceedings Paper CT Conference on Lidar Remote Sensing for Environmental Monitoring XIV CY AUG 25-26, 2013 CL San Diego, CA SP SPIE DE Atmospheric profiling; lidar equation; assumptions; implicit premises ID DISTORTIONS AB The distortions of the inverted lidar signals can be caused by (i) the constant offset that remains in the backscatter signal after removing the background component, (ii) the multiplicative distortion component, which level is related with the lidar signal intensity, and (iii) the signal noise in the wide wavelength spectra; the latter includes low-frequency components, which do not obey common random-noise statistics. These distortions, even minor, may yield significant distortions in the retrieved outputs obtained by the inversion of the lidar signal. Implicit and explicit premises and assumptions required for any solution of the lidar equation are additional sources of the uncertainty in the inversion results. There is no reliable way for checking whether used assumptions are valid, therefore, the lidar signal inversion can yield significantly biased results. As a result, instead some statistically mean profile of the atmospheric parameter of interest with the corresponding probability function, one obtains some qualitative estimate of the profile with unknown uncertainty, which depends on the validity of used assumptions. It means that lidar profiling is not a measurement but a result of some simulation based on past observations.

The material properties of these "green" hybrid aerogels were characterized extensively using various techniques. It was found that adding a small amount of CNFs and MWCNTs increased the mechanical properties of the PVA aerogels drastically. The mechanical properties of the hybrid aerogels showed an exponential dependency on the relative aerogel densities. These low-density hybrid aerogels also exhibited very low thermal conductivities and high surface areas, thereby making them potentially useful for many applications including thermal insulation and structural components.

Comparative analyses have revealed that the Fusarium genome is compartmentalized into regions responsible for primary metabolism and reproduction (core genome), and pathogen virulence, host specialization, and possibly other functions (adaptive genome). Genes involved in virulence and host specialization are located on pathogenicity chromosomes within strains pathogenic to tomato (Fusarium oxysporum f. sp. lycopersici) and pea (Fusarium 'solani' f. sp. pisi). The experimental transfer of pathogenicity chromosomes from F. oxysporum f. sp. lycopersici into a nonpathogen transformed the latter into a tomato pathogen. Thus, horizontal transfer may explain the polyphyletic origins of host specificity within the genus. Additional genome-scale comparative and functional studies are needed to elucidate the evolution and diversity of pathogenicity mechanisms, which may help inform novel disease management strategies against fusarial pathogens.

In wheat, access to this diversity and its exploitation is based upon the genetic distance of the wild species relatives from the wheat genomes. For several decades, these wide crosses have been a reservoir of novel variation for wheat improvement. Among these, close relatives of the primary gene pool have been preferred since this ensures successful gene transfer as they permit homologous genetic exchanges to occur between related genomes, as exemplified by the A and D genome diploid progenitors. One strategy has been based upon first producing genetic stocks that capture the potential of the diploids via bridge crossing where the D genome synthetic hexaploid wheats (2n = 6x = 42, AABBDD) are exploited. The synthetics are products of crosses between elite durum wheat cultivars (Triticum turgidum) and various Aegilops tauschii accessions. Similarly, the diversity of the A and B genomes has also been assembled as AABBAA (T. turgidum/A genome diploids Triticum boeoticum, Triticum monococcum, Triticum urartu) and AABBBB (SS) (T. turgidum/Aegilops speltoides). The utilization of these useful diversity for various biotic/abiotic stresses including in the development of molecular tools for enhancing breeding efficiency has been in the forefront of wheat improvement over the past two decades. Additional strategy employed includes the direct crosses between parental diploids and recipient wheat cultivars extended to give even swifter products by top- or backcrossing the F-1 combinations with either durum or bread wheats. Relatively less progress has been made in the use of genes from tertiary gene pool often involving "intergeneric crosses." The potency of potentially useful diversity in tertiary gene pool warrants further exploitation of this resource. Presented here are major facets of intergeneric hybridization embracing a taxonomic consideration of genetic diversity within the Triticeae, the exploitation protocols, prebreeding strategies, and some of the outputs from distant hybridization with a major focus on wheat/alien chromosomal exchanges classed as "translocations" such as T1BL.1RS and to a lesser degree the T1AL.1RS Robertsonian translocations. This chapter also attempts to relate the exploitation of the Triticeae genetic diversity with wheat productivity as a means of addressing diverse stress constraints that if pursued will provide yield enhancing outputs necessary for overriding environmental limitations of climate change, unpredictable incidences of biotic stresses, and catalyzing gains for food security with wheat.

A novel solvent-exchange method was first developed to prepare graphene oxide/ethylene glycol (GO/EG) dispersions in a reactor equipped with a fractionating device. The prepared dispersions were applied successively to fabricate unsaturated polyester composites via in situ melt polycondensation in the same reactor. The dispersion behavior of GO/EG dispersions was characterized by atomic force microscopy (AFM). The structures and properties of the as-prepared FGS/polyester nanocomposites were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), tensile tests, thermogravimetric analysis, and dynamic mechanical analysis. The results of AFM show that GO nanosheets are well exfoliated in EG solvent. The results of FT-IR, XRD, Raman, SEM, and TEM indicate that the FGS are also finely exfoliated in the polyester matrix and have strong interaction with the host polymer. Compared with the neat UPR matrix, the composite with an extremely low content of 0.08 wt% FGS exhibits maximum increases of 53.6% and 48.4% in tensile strength and modulus; the composite with 0.32 wt% FGS has a 10.7 degrees C increase in thermal decomposition temperature and a 17.9 degrees C increase in glass transition temperature. Therefore, building on this work to generate unsaturated polyester nanocomposites with improved properties at reduced cost is possible.

Preparation of stable substrates using simple methods is a current priority in SERS research. Biopolymer encapsulated with silver nanoparticle (BeSN) substrate was prepared by reducing silver nitrate into silver using trisodium citrate with addition of polyvinyl alcohol as a stablizer. Optical properties of biopolymer based silver nanoparticles were analyzed with UV/Vis spectroscopy as well as hyperspectral imaging microscopy. UV/Vis spectra showed plasmon resonance absorption at 460 nm; distinct plasmon resonance peak from the hyperspectral imaging spectral profile explained homogeneous nature of SERS substrates. SERS signals of trans-1,2-bis(4-pyridyl)ethylene (BPE) and Rhodamine 6G were measured to check substrate repeatability. Good signal repeatability was observed with less noise and spot-to-spot variation from substrates prepared at various times. The SERS substrates were used to detect and differentiate two different serotypes (Typhimurium and Enteritidis) of Salmonella spp. In addition to Salmonella spp., other foodborne pathogens such as E. coli, Listeria innocua, Staphylococcus aureus and also Salmonella Infantis were detected using the BeSN SERS substrates. SERS spectral data were obtained with a HeNe laser of 785 nm excitation, between 400 and 1800cm(-1) from 15 different spots of a target sample on the substrate at three different times. Principal component analysis (PCA) was carried out to differentiate Salmonella serotypes, resulting in a total of 98% variation among the serotypes. SERS spectral comparison of different serotypes indicated that they have similar cell wall and cell membrane structures which were identified by spectral regions distinctively between 520 and 1050 cm(-1). Major differences between serotypes were observed between 1200 and 1700 cm(-1) which represents biochcemical characteristics of DNA and RNA components of the cells.

This chapter reports the recent development on the use of aligned silver nanorod (AgNR) arrays prepared by oblique angle deposition, as surface-enhanced Raman scattering (SERS) substrates to detect food safety related substances such as foodborne pathogens, toxins, pesticides, and adulteration agents. Our investigation demonstrated that the AgNR based SERS can be used to distinguish different types and serotypes of bacteria. It can also be used to discriminate mycotoxins of similar chemical structures, such as aflatoxins, with the help of chemometric analysis of the SERS spectra. Pesticides from real food samples, such as tea, can be identified using this method with the same multivariate statistical analysis. When combining SERS with ultra-thin layer chromatography using the AgNR substrates, our detection system can achieve simultaneous separation and detection of mixture samples, which could be critical for real food detection.

External introduced toxins or internal spoilage correlated pathogens and their metabolites are all potential sources of food toxins. To prevent unsafe food from circulating in the market, many food toxin detection techniques have been developed to detect various toxins for quality control. Although several routine techniques address the most important food safety issues, many challenges still exist in terms of sensitivity, cost and speed, especially for lethal proteinaceous toxins. Atomic force microscope (AFM) is being widely used for nanotechnology imaging or as a force measurement tool for biophysics and molecular biology. Its super-sensitivity in probing specific binding interactions between molecules is also applicable for food toxin detection. This chapter provides a brief summary about the development of AFM and different imaging operation modes from applications and characteristics. AFM detection applications for the cantilever sensing and recognition image techniques are discussed in detail for two categories of surfaces: silicon and metal surface. Furthermore, the recent progress in various aspects of AFM based sensor techniques are discussed with successful applications in food toxin detection provided as examples. The super-sensitivity and easy user accessibility make these AFM techniques good candidates for applications in the field. Challenges in the further application of AFM techniques are similar to those of the general field of biosensing, and include chemical scheme strategies, sensing modulus and substrate development. Through the mutual advances in several scientific disciplines, including materials, chemistry and molecular biology, AFM-based food toxin detection techniques will see more broad applications.

It is a renewable, microporous, carbon-rich product that also contains nitrogen, hydrogen, oxygen, and ash. Several varieties of biochar are very porous with irregular surface areas. The pore size and distribution of a given biochar can affect its utility, and controlling the highest treatment temperature during the pyrolysis process is the most common way to affect this. Chemical and physical activation methods are another means to modify the pore size and/or distribution. Biochar can be produced from a very wide range of agricultural and wood-based waste streams and applications of biochar include carbon sequestration, soil amendment, and sorption of several classes of undesirable components from water, soil, or industrial processes. Additionally, recent research has shown potential in using biochar with high pore volume concentration as a filler for rubber composites.

The least-cost-plus-net-value-change model of wildland fire economics includes benefits of wildfire in a framework for evaluating suppression options. In this study, we estimated one component of that benefit - the expected present value of the reduction in suppression costs for subsequent fires arising from the fuel treatment effect of a current fire. To that end, we employed Monte Carlo methods to generate a set of scenarios for subsequent fire ignition and weather events, which are referred to as sample paths, for a study area in central Oregon. We simulated fire on the landscape over a 100-year time horizon using existing models of fire behaviour, vegetation and fuels development, and suppression effectiveness, and we estimated suppression costs using an existing suppression cost model. Our estimates suggest that the potential cost savings may be substantial. Further research is needed to estimate the full least-cost-plus-net-value-change model. This line of research will extend the set of tools available for developing wildfire management plans for forested landscapes.

This study's primary objective was to evaluate correlations between drought and fire-danger-rating indices representing short- and long-term drought, to determine which had the strongest relationships with large fire occurrence at the scale of the western United States during the years 1984-2008. We combined 4-8-km gridded drought and fire-danger-rating indices with information on fires greater than 404.7ha (1000acres). To account for differences in indices across climate and vegetation assemblages, indices were converted to percentile conditions for each pixel. Correlations between area burned and short-term indices Energy Release Component and monthly precipitation percentile were strong (R-2=0.92 and 0.89), as were correlations between number of fires and these indices (R-2=0.94 and 0.93). As the period of time tabulated by indices lengthened, correlations with fire occurrence weakened: Palmer Drought Severity Index and 24-month Standardised Precipitation Index percentile showed weak correlations with area burned (R-2=0.25 and -0.01) and number of large fires (R-2=0.3 and 0.01). These results indicate associations between short-term indices and moisture content of dead fuels, the primary carriers of surface fire.

Complete derivation of the wind limit as a function of reaction intensity is given, along with an alternate result based on a changed assumption. Evidence indicates that both the original and the revised wind limits are too restrictive. Wind limit is based in part on data collected on the 7 February 1967 Tasmanian grassland fires. A reanalysis of the data indicates that these fires might not have been spreading in fully cured continuous grasslands, as assumed. In addition, more recent grassfire data do not support the wind speed limit. The authors recommend that, in place of the current wind limit, rate of spread be limited to effective midflame wind speed. The Rothermel model is the foundation of many wildland fire modelling systems. Imposition of the wind limit can significantly affect results and potentially influence fire and fuel management decisions.

TI AIRSPEED AND ORIFICE SIZE AFFECT SPRAY DROPLET SPECTRUM FROM AN AERIAL ELECTROSTATIC NOZZLE FOR FIXED-WING APPLICATIONS SO APPLIED ENGINEERING IN AGRICULTURE LA English DT Article DE Electrostatic charging; Aerial application; Aerial spraying; Agricultural aviation; Spray droplet spectrum; Laser diffraction ID CHARGING AIRCRAFT; REDUCED-VOLUME; COTTON; DEPOSITION; FOLIAR; SYSTEM; FIELD AB The aerial electrostatic spraying system patented by the USDA-ARS is a unique aerial application system which inductively charges spray particles for the purpose of increasing deposition and efficacy. While this system has many potential benefits, very little is known about how changes in airspeed or nozzle orifice size affect the spray droplet spectrum of charged spray. This study quantified these effects in a controlled high-speed wind tunnel at fixed-wing airspeeds (177-306 km/h). These tests were conducted at the USDA-ARS Aerial Application Technology research facilities in College Station, Texas. Laser diffraction data showed that increases in airspeed produced smaller spray droplets for all nozzle orifices tested, as quantified by standard spray droplet parameters. Generally, an increase in nozzle orifice size increased the coarseness of the spray droplet spectra at all airspeeds. The results from this study will help aerial applicators better understand how changes in airspeed and nozzle orifice size affect droplet size from an aerial electrostatic nozzle. C1 [Martin, D.

TI RICE PRODUCTION WITH CENTER PIVOT IRRIGATION SO APPLIED ENGINEERING IN AGRICULTURE LA English DT Article DE Irrigation; Rice; Center pivot irrigation; Rice irrigation; Water management ID FLOOD IRRIGATION; SPRINKLER AB While continuous-flood irrigation, the most common method for U.S. rice production, can have a fairly high irrigation application efficiency, factors such as soil variability and the size of most Mid-South farming operations often combine to reduce the efficiency. Center pivot irrigation is a way to reduce irrigation water use in some cases and allow rice in the crop rotation in other situations when flooding is not practical. Rice was produced at the University of Missouri Fisher Delta Research Center Marsh Farm at Portageville in 2009 and 2010 and irrigated every other day with a 150-m-long center pivot irrigation system. An experimental crop coefficient function was developed and included in a beta version of the Arkansas Irrigation Scheduler (AIS). It was used with daily short grass reference evapotranspiration (ETo) calculated from weather data collected on site to estimate the daily soil water deficit (SWD). Weather conditions were warmer and much drier in 2010 and ETo was higher each month. In 2009, there were totals of 34 days with irrigation and 414 mm of water applied. In 2010, there were totals of 45 days with irrigation and 503 mm of irrigation water applied. In 2009, the cultivar Templeton had the highest observed grain yield (8.31 Mg ha(-1)) and irrigation water use efficiency (IWUE; 2.0 kg m(-3)). In 2010, the cultivar Francis had the highest observed grain yield (8.2 Mg ha(-1)) and IWUE (1.6 kg m(3)). In addition to the higher temperatures in 2010, yields were probably impacted by the fact that rice was produced in the field the two previous years. Future research will use the beta version of the AIS to schedule irrigations, which should indicate whether the crop coefficient is adequate and allow producers a system for scheduling center pivot irrigation on rice.

TI SUSTAINABLE UTILIZATION OF THE CALERA AQUIFER, ZACATECAS, MEXICO SO APPLIED ENGINEERING IN AGRICULTURE LA English DT Article DE Groundwater; Irrigation; Water Conservation; Sustainability AB Groundwater extraction from the Calera Aquifer in the State of Zacatecas, Mexico, for irrigation, urban, and industrial uses has increased over recent decades to unsustainable levels. The annual groundwater deficit was estimated to be 172.5 (10(6) m(3)/yr) and groundwater table elevation to drop by 1.15 (m) per year Irrigated agriculture used about 84% [207.6 (10(6) m(3)/yr)] of total extracted groundwater, urban 10% [24.1 (10(6) m(3)/yr)], and industry 6% [15.4 (10(6) m(3)/yr)]. An annual, watershed-scale water budget analysis was conducted to evaluate alternative water management and conservation scenarios and determine their effectiveness at slowing the rate of groundwater depletion. The most restrictive scenario called for a 10% reduction in industrial and urban water use and a 50% reduction in irrigation water in the first decade after year 2015, and an additional 10% reduction in irrigation water every decade after year 2025. According to this latter scenario, annual groundwater deficit would decrease to 45.5 (10(6) m(3)/yr) by year 2045, groundwater table would be 18.1 (m) lower than that in year 2015, and groundwater table elevation would drop 0.3 (m) per year: The 50% reduction in irrigation water was achieved by upgrading inefficient surface irrigation to sprinkler and drip irrigation; converting under-performing crops (oats and maize) to rain fed cropland; switching 30% of the irrigated dry bean crop to canola, a more water efficient crop; and, taking 15% of onion, garlic, and red pepper crops out of irrigated production. Additional cropland will have to be taken out of irrigation to meet water use targets set for 2035 and 2045. This water management scenario would extend the useful life of the aquifer and represents a great improvement over current unsustainable groundwater extraction. However, curtailing irrigated agriculture to a point where profitable crops must be taken out of production may not be an acceptable solution from a political and socioeconomic standpoint because it would greatly impact the region's agricultural economy.

SO GENOME BIOLOGY LA English DT Article ID EARLY DIVERSIFICATION; DIVERGENCE TIMES; CORE EUDICOTS; SEQUENCE; GENE; PALEOHEXAPLOIDY; EVOLUTION; FRUITS; PLANTS; RATES AB Background: Sacred lotus is a basal eudicot with agricultural, medicinal, cultural and religious importance. It was domesticated in Asia about 7,000 years ago, and cultivated for its rhizomes and seeds as a food crop. It is particularly noted for its 1,300-year seed longevity and exceptional water repellency, known as the lotus effect. The latter property is due to the nanoscopic closely packed protuberances of its self-cleaning leaf surface, which have been adapted for the manufacture of a self-cleaning industrial paint, Lotusan. Results: The genome of the China Antique variety of the sacred lotus was sequenced with Illumina and 454 technologies, at respective depths of 101x and 5.2x. The final assembly has a contig N50 of 38.8 kbp and a scaffold N50 of 3.4 Mbp, and covers 86.5% of the estimated 929 Mbp total genome size. The genome notably lacks the paleo-triplication observed in other eudicots, but reveals a lineage-specific duplication. The genome has evidence of slow evolution, with a 30% slower nucleotide mutation rate than observed in grape. Comparisons of the available sequenced genomes suggest a minimum gene set for vascular plants of 4,223 genes. Strikingly, the sacred lotus has 16 COG2132 multi-copper oxidase family proteins with root-specific expression; these are involved in root meristem phosphate starvation, reflecting adaptation to limited nutrient availability in an aquatic environment. Conclusions: The slow nucleotide substitution rate makes the sacred lotus a better resource than the current standard, grape, for reconstructing the pan-eudicot genome, and should therefore accelerate comparative analysis between eudicots and monocots.

Both species are tractable both genetically and in the greenhouse, and for both, substantial sets of tools and resources for molecular genetic research have been assembled. As sequencing costs have declined, however, additional legume genomes have been sequenced, and the funding available to crops such as soybean has enabled these to be developed to the status of genetic models in their own right. This chapter, therefore, describes a broader set of model species in the legumes, and discusses similarities and differences between the genomes sequenced to date, as well as computational resources available for various legume species. Genome structural characteristics in, for example, Medicago truncatula and Glycine max, can have large impacts on the kinds of functional genomic research that may be carried out in these species. Both of these genomes have substantial redundancy for many gene families, but the nature of the redundancy is different in the two genomes-with the redundancy typically being in the form of local gene duplications in Medicago, and in whole-genome-duplication-derived duplications in Glycine. Similar considerations (about gene environments and genome structure) will likely need to be taken into account for any model or crop species. C1 ARS, USDA, Ames, IA USA.

The technique relies on analysis of large DNA fragments generated by the cleavage of intact bacterial chromosomes with a rare cutting restriction enzyme, subsequently resolved by pulsed-field electrophoresis with periodic changes of the orientation of the electrical field across the gel. The high discriminatory power, improved reproducibility due to standardization of experimental protocols and data interpretation guidelines, and establishment of a national PFGE database of S. aureus profiles have made it a valuable means for global tracking of S. aureus infection sources and determination of genetic relatedness of outbreak isolates.

Feeding by navel orangeworm larvae causes physical damage resulting in lower kernel quality; more importantly larvae are purported to vector the aflatoxigenic fungi. Aflatoxins are toxic metabolites produced by aspergilli and represent a major food safety concern. Over the years volatile natural products have played a large role in efforts to control or monitor navel orangeworm moths. The two most important sources of relevant natural products have been female navel orangeworm, which produce a complex sex pheromone blend; and, the almond host plant, which has recently been described as the source of a blend of volatiles that attract both male and female navel orangeworm. Provided herein is an overview of natural products and their role in efforts to control or monitor navel orangeworm moths in California almonds, pistachios, and walnuts.

Area wide management plans aimed at reducing the incidence and spread of Huanglongbing rely upon sampling ACP with yellow sticky cards, which are not always reliable. The development of highly effective scent attractants may improve trapping efficacy, which, in turn, is needed to increase the reliability of vector detection and monitoring and to reduce costs associated with these activities. The protein components of the insect olfactory system can control and alter insect behavior; thus, these proteins are suitable targets for the development of novel control products using rational design, as has been accomplished for drug discovery in the pharmaceutical industry. Odorant binding proteins (OBPs) from ACP were recombinantly expressed in vitro and screened for their ability to bind to petitgrain oil, an essential oil from sour orange foliage known to attract ACP, in order to identify OBP(s) responsible for attraction behavior. The OBP that bound petitgrain oil was then screened with a combinatorial chemical library comprising 30,000 small molecules in order to isolate synthetic ligands; these ligands were subsequently evaluated for their behavioral effects on ACP. A synthetic ligand named 'Titan' was found to be behaviorally active in preliminary tests; Titan was tested further with respect to its abilities to stimulate two foraging behaviors of ACP and to interact with limonene, a monoterpene emitted by many ACP host plant species. The addition of Titan to limonene increased the amount of probing by ACP into an artificial midrib composed of an emulsified wax relative to the probing level elicited by limonene alone. Probing level to Titan alone was influenced by the concentration of Titan in the wax midrib, with the lower concentration being more stimulatory than the higher concentration. In olfactometer tests, response to Titan was similar to the odor of young orange jasmine foliage. Olfactory response was also higher to a mixture of limonene and Titan than to limonene alone. These results demonstrated that Titan is highly stimulatory and modifies psyllid response to limonene. Further tests will determine whether Titan can be used in concert with naturally occurring terpenes to develop potent scent attractants for ACP.

Most of these repeats occur as abundant transposable elements (TEs), which present unique challenges to sequence, assemble, and annotate genomes. Multiple copies of Long Terminal Repeat (LTR) retrotransposons can hinder sequence assembly and also cause problems with gene annotation. TEs can also contain protein-encoding genes, the ancient remnants of which can mislead gene identification software if not correctly masked. Hence, accurate assembly is crucial for gene annotation. We present TEnest v2.0. TEnest computationally annotates and chronologically displays nested transposable elements. Utilizing organism-specific TE databases as a reference for reconstructing degraded TEs to their ancestral state, annotation of repeats is accomplished by iterative sequence alignment. Subsequently, an output consisting of a graphical display of the chronological nesting structure and coordinate positions of all TE insertions is the result. Both linux command line and Web versions of the TEnest software are available at www.wiselab.org and www.plantgdb.org/tool/, respectively.

Despite a significant body of research studying the physiology of lipid droplets it has not yet been possible to fully determine the composition of individual cellular lipid droplets. In this paper we use Raman spectroscopy on single cellular lipid droplets and least-squares fitting of pure fatty acid spectra to determine the composition of individual lipid droplets in cells after treatment with different ratios of oleic and palmitic acid. We validate the results of the Raman spectroscopy-based single lipid droplet analysis with results obtained by gas chromatography analysis of millions of cells, and find that our approach can accurately predict the relative amount of a specific fatty acid in the lipid droplet. Based on these results we show that the fatty acid composition in individual lipid droplets is on average similar to that of all lipid droplets found in the sample. Furthermore, we expand this approach to the investigation of the lipid composition in single cellular peroxisomes. We determine the location of cellular peroxisomes based on two-photon excitation fluorescence (TPEF) imaging of peroxisomes labeled with the green fluorescent protein, and successive Raman spectroscopy of peroxisomes. We find that in some cases peroxisomes can produce a detectable CARS signal, and that the peroxisomal Raman spectra exhibit an oleic acid-like signature.

We simulate first-order autoregressive models with known parameters and show that zeta is a function of variance and autocorrelation of a time series. We then use 500 random tree-ring data sets with unknown parameters and show that zeta is at best equivalent to the standard deviation of a time series in cases without high autocorrelation and is an inefficient estimator of the coefficient of variation. It is hard to justify the use of zeta as a useful, descriptive statistic in dendrochronology on theoretical or empirical grounds. It is better to make a thorough evaluation of the time series properties of a data set and we suggest various avenues for doing so including some that are maybe unfamiliar to most dendrochronologists including generalized autoregressive conditional heteroscedasticity (GARCH) models.

TI GROWTH, YIELD, AND ION RELATIONS OF STRAWBERRY IN RESPONSE TO IRRIGATION WITH CHLORIDE-DOMINATED WATERS SO JOURNAL OF PLANT NUTRITION LA English DT Article DE chloride toxicity; fruit yield; ion partitioning; sodium exclusion ID PLANT SALT TOLERANCE; NACL SALINITY; SUPPLEMENTARY POTASSIUM; CALCIUM NITRATE; FRUIT-QUALITY; CULTIVARS; STRESS; TRANSPORT; ACCUMULATION; GLASSHOUSE AB Strawberry is listed as the most salt sensitive fruit crop in comprehensive salt tolerance data bases. Recently, concerns have arisen regarding declining quality of irrigation waters available to coastal strawberry growers in southern and central California. Over time, the waters have become more saline, with increasing sodium (Na+) and chloride (Cl-). Due to the apparent extreme Cl- sensitivity of strawberry, the rising Cl- levels in the irrigation waters are of particular importance. In order to establish the specific ion causing yield reduction in strawberry, cultivars Ventana' and Camarosa' were grown in twenty-four outdoor sand tanks at the ARS-USDA U. S. Salinity Laboratory in Riverside, CA and irrigated with waters containing a complete nutrient solution plus Cl- salts of calcium (Ca2+), magnesium (Mg2+), Na+, and potassium (K+). Six salinity treatments were imposed with electric conductivities (EC) = 0.835, 1.05, 1.28, 1.48, 1.71, and 2.24 dS m(-1), and were replicated four times. Fresh and dry weights of Camarosa' shoots and roots were significantly higher than those of Ventana' at all salinity levels. Marketable yield of Camarosa' fruit decreased from 770 to 360g/plant as salinity increased and was lower at all salinity levels than the yield from the less vigorous Ventana' plants. Ventana' berry yield decreased from 925 to 705g/plant as salinity increased from 0.835 to 2.24 dS m(-1). Relative yield of Camarosa' decreased 43% for each unit increase in salinity once irrigation water salinity exceeded 0.80 dS m(-1). Relative Ventana' yield was unaffected by irrigation water salinity up to 1.71 dS m(-1), and thereafter, for each additional unit increase in salinity, yield was reduced 61%. Both cultivars appeared to possess an exclusion mechanism whereby Na+ was sequestered in the roots, and Na+ transport to blade, petiole and fruit tissues was limited. Chloride content of the plant organs increased as salinity increased to 2.24 dS m(-1) and substrate Cl increased from 0.1 to13mmol(c)L(-1). Chloride was highest in the roots, followed by the leaves, petioles and fruit. Based on plant ion relations and relative fruit yield, we determined that, over the range of salinity levels studied, specific ion toxicity exists with respect to Cl-, rather than to Na+ ions, and, further, that the salt tolerance threshold is lower for Camarosa' than for Ventana'.

In a favorable climate, the percentage of crawlers settling on a tree from very heavily infested fruit discarded when crawlers were emerging, from fruit with a long shelf life, and from fruit discarded near a tree, was low. Infestation was higher when fruit was in contact with the tree than when it was placed 2 m away. It is concluded that establishment via the pathway of commercially produced fruit for consumption is low, because such fruit has not been observed to be as heavily infested, and is not as likely to be discarded in an orchard as was the study fruit. A second part of the study investigated if fruit handlers could become infested with crawlers and be a pathway for establishment. Fruit handlers did receive a low percentage of crawlers on their clothes when they engaged in brushing crawlers from heavily (>5000 crawlers per fruit) infested fruit in the laboratory. Importantly, the pathway from the handlers' clothes to trees in an orchard has not been demonstrated. Good sanitation and safeguarding practices in the packing houses and the orchards can further ensure the prevention of armored scale introduction via the commodity intended for human consumption.

To distinguish the contributions of SOC and sugarcane (Saccharum spp.) residues to the short-term CO2-C loss, we studied the influence of several tillage systems: heavy offset disk harrow (HO), chisel plow (CP), rotary tiller (RT), and sugarcane mill tiller (SM) in 2008, and CP, RT, SM, moldboard (MP), and subsoiler (SUB) in 2009, with and without sugarcane residues relative to no-till (NT) in the sugarcane producing region of Brazil. Soil CO2-C emissions were measured daily for two weeks after tillage using portable soil respiration systems. Daily CO2-C emissions declined after tillage regardless of tillage system. In 2008, total CO2-C from SOC and/or residue decomposition was greater for RT and lowest for CP. In 2009, emission was greatest for MP and CP with residues, and smallest for NT. SOC and residue contributed 47 % and 41 %, respectively, to total CO2-C emissions. Regarding the estimated emissions from sugarcane residue and SOC decomposition within the measurement period, CO2-C factor was similar to sugarcane residue and soil organic carbon decomposition, depending on the tillage system applied. Our approach may define new emission factors that are associated to tillage operations on bare or sugarcane-residue-covered soils to estimate the total carbon loss.

Kenaf is a fast-growing dicotyledonous plant valued for its biomass. F5H, a cytochrome P450-dependent monooxygenase (CYP84), is a key enzyme for syringyl lignin biosynthesis. The full length of the F5H ortholog was cloned and characterized. The full-length F5H ortholog consists of a 1,557-bp open reading frame (ORF) encoding 518 amino acids (GenBank Accession number JX524278). The deduced amino acid sequence showed that kenaf F5H had the highest similarity (78%) with that of Populus trichocarpa. Transcriptional analysis of F5H ortholog was conducted using quantitative real-time PCR during the developmental stages of various tissues and in response to various abiotic stresses. The highest transcript level of the F5H ortholog was observed in immature flower tissues and in early stage (6 week-old) of stem tissues, with a certain level of expression in all tissues tested. The highest transcript level of F5H ortholog was observed at the late time points after treatments with NaCl (48 h), wounding (24 h), cold (24 h), abscisic acid (24 h), and methyl jasmonate (24 h).

The circadian clock is operated by genes and comprises a central clock in the brain that responds to environmental cues and controls subordinate clocks in peripheral tissues via circadian output pathways. The central and peripheral clocks coordinately generate rhythmic gene expression in a tissue-specific manner in vivo to couple diverse physiological and behavioral processes to periodic changes in the environment. However, with the industrialization of the world, activities that disrupt endogenous homeostasis with external circadian cues have increased. This change in lifestyle has been linked to an increased risk of diseases in all aspects of human health, including cancer. Studies in humans and animal models have revealed that cancer development in vivo is closely associated with the loss of circadian homeostasis in energy balance, immune function, and aging, which are supported by cellular functions important for tumor suppression including cell proliferation, senescence, metabolism, and DNA damage response. The clock controls these cellular functions both locally in cells of peripheral tissues and at the organismal level via extracellular signaling. Thus, the hierarchical mammalian circadian clock provides a unique system to study carcinogenesis as a deregulated physiological process in vivo. The asynchrony between host and malignant tissues in cell proliferation and metabolism also provides new and exciting options for novel anticancer therapies.

TI Forest carbon benefits, costs and leakage effects of carbon reserve scenarios in the United States SO JOURNAL OF FOREST ECONOMICS LA English DT Article DE Forest carbon; Carbon reserve; Carbon price; Carbon leakage; Climate change mitigation; Mitigation cost; Present value; Set asides ID WOOD ENERGY-CONSUMPTION; SEQUESTRATION; MARKET; LAND; PRODUCTS; IMPACTS; PROGRAM; MODELS AB This study evaluated the potential effectiveness of future carbon reserve scenarios, where U.S. forest landowners would hypothetically be paid to sequester carbon on their timberland and forego timber harvests for 100 years. Scenarios featured direct payments to landowners of $0 (baseline), $5, $10, or $15 per metric ton of additional forest carbon sequestered on the set aside lands, with maximum annual expenditures of $3 billion. Results indicated that from 1513 to 6837 Tg (Teragrams) of additional carbon (as carbon dioxide equivalent, CO(2)e) would be sequestered on U.S. timberlands relative to the baseline case over the next 50 years (30-137 Tg CO(2)e annually). These projected amounts of sequestered carbon on timberlands take into account projected increases in timber removal and forest carbon losses on other timberlands (carbon leakage effects). Net effectiveness of carbon reserve scenarios in terms of overall net gain in timberland carbon stocks from 2010 to 2060 ranged from 0.29 tCO(2)e net carbon increase for a payment of $5/tCO(2)e to the landowner (71% leakage), to 0.15 tCO(2)e net carbon increase for a payment of $15/tCO(2)e to the landowner (85% leakage). A policy or program to buy carbon credits from landowners would need to discount additions to the carbon reserve by the estimated amount of leakage. In the scenarios evaluated, the timber set-asides reduced timberland area available for harvest up to 35% and available timber inventory up to 55%, relative to the baseline scenario over the next 50 years, resulting in projected changes in timber prices, harvest levels, and forest product revenues for the forest products sector.

This paper examines landowner preferences for the attributes of working forest conservation contracts (WFCC) using a choice experiment. The attributes examined are contract duration (from 10 years to perpetuity), forest management requirements, and the extent of forestland covered under the contract. We find that contract attributes are valued very differently depending on landowner objectives and harvesting behavior. Landowner characteristics and forestland spatial characteristics including distances to development and large public forestlands were found to significantly influence the likelihood of contract acceptance. While a significant portion of preference heterogeneity remains unobserved, we identify several key sources of landowner preference heterogeneity which allows for a better understanding of which landowners are likely to enroll in voluntary forest conservation contracts and may have implications for improved targeting of contracts.

To many, the Anthropocene is an era of environmental doom that unless reversed, will result in catastrophic reductions in biodiversity. An alternate view is that the biota will adjust to the new environmental conditions and through processes of species mixing and self-organization will form sustainable novel communities of organisms. Using examples from Puerto Rico, I discuss the conditions that lead to novel forest formation and the characteristics of these forests, including their species composition. Novel forests include native tree and animal species as well as significant numbers of introduced and naturalized species. These introduced species dominate forest stands, and their dominance is not incompatible with the regeneration of native species. I propose that these types of ecosystems might represent the natural response of the biota to the Anthropocene. C1 US Forest Serv, Int Inst Trop Forestry, USDA, Rio Piedras, PR 00926 USA.

The majority of mammary gland development occurs postnatally, and the mammary gland undergoes cyclical periods of growth, differentiation, lactation, and regression that are coordinated to provide nutrients for offspring or are driven by strategies to manage reproduction and milk production of domesticated species. Growth and maintenance of the mammary epithelium depends on the function of mammary stem cells and progenitor cells. In this review, we provide an overview of postnatal mammary gland development, cyclical phases of mammary gland regression ( regression during lactation and between successive lactations), and mammary stem cells and progenitor cells. Where possible, these processes are related to animal production and compared across species, particularly bovine, porcine, murine, and human.

The generation of the chicken genome sequence and the availability of other empowering tools and resources greatly enhance the ability to select for enhanced disease resistance via genetic markers and to understand more deeply the biological basis of host resistance. In this review, we discuss how integrated genomic approaches are able to identify specific genes and genetic markers associated with disease resistance, give select examples of contemporary work involving various genomic strategies to identify disease resistance genes, and finish by giving some final thoughts on predicted applications in the near future.

Simple-stomached species such as swine, poultry, and fish require extrinsic phytase to digest phytate, the major form of phosphorus in plant-based feeds. Consequently, this enzyme is supplemented in these species' diets to decrease their phosphorus excretion, and it has emerged as one of the most effective and lucrative feed additives. This chapter provides a comprehensive review of the evolving course of phytase science and technology. It gives realistic estimates of the versatile roles of phytase in animal feeding, environmental protection, rock phosphorus preservation, human nutrition and health, and industrial applications. It elaborates on new biotechnology and existing issues related to developing novel microbial phytases as well as phytase-transgenic plants and animals. And it targets critical and integrated analyses on the global impact, novel application, and future demand of phytase in promoting animal agriculture, human health, and societal sustainability.

Nutrient deficiencies after surgery are common and have multiple causes. Preoperative factors include obesity, which appears to be associated with risk for several nutrient deficiencies, and preoperative weight loss. Postoperatively, reduced food intake, suboptimal dietary quality, altered digestion and absorption, and nonadherence with supplementation regimens contribute to risk of deficiency. The most common clinically relevant micronutrient deficiencies after gastric bypass include thiamine, vitamin B-12, vitamin D, iron, and copper. Reports of deficiencies of many other nutrients, some with severe clinical manifestations, are relatively sporadic. Diet and multivitamin use are unlikely to consistently prevent deficiency, thus supplementation with additional specific nutrients is often needed. Though optimal supplement regimens are not yet defined, most micronutrient deficiencies after gastric bypass currently can be prevented or treated by appropriate supplementation.

The knowledge that metabolic pathways may be altered in individuals with genetic variants in the presence of certain dietary exposures offers great potential for personalized nutrition advice. However, although considerable resources have gone into improving technology for measurement of the genome and biological systems, dietary intake assessment remains inadequate. Each of the methods currently used has limitations that may be exaggerated in the context of gene x nutrient interaction in large multiethnic studies. Because of the specificity of most gene x nutrient interactions, valid data are needed for nutrient intakes at the individual level. Most statistical adjustment efforts are designed to improve estimates of nutrient intake distributions in populations and are unlikely to solve this problem. An improved method of direct measurement of individual usual dietary intake that is unbiased across populations is urgently needed.

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

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

The virus exists as a complex of strains that induce a wide variety of foliar and tuber symptoms in potato, leading to yield reduction and loss of tuber quality. PVY has displayed a distinct ability to evolve through accumulation of mutations and more rapidly through recombination between different strains, adapting to new potato cultivars across different environments. Factors behind PVY emergence as a serious potato threat are not clear at the moment, and here an attempt is made to analyze various properties of the virus and its interactions with potato resistance genes and with aphid vectors to explain this recent PVY spread in potato production areas. Recent advances in PVY resistance identification and mapping of corresponding genes are described. An updated classification is proposed for PVY strains that takes into account the most current information on virus molecular genetics, serology, and host reactivity.

TI Present and future nitrogen deposition to national parks in the United States: critical load exceedances SO ATMOSPHERIC CHEMISTRY AND PHYSICS LA English DT Article ID ATMOSPHERIC NITROGEN; CLIMATE-CHANGE; ADJOINT MODEL; AIR-QUALITY; EMISSIONS; AMMONIA; SULFUR; THRESHOLDS; MANAGEMENT; VEGETATION AB National parks in the United States are protected areas wherein the natural habitat is to be conserved for future generations. Deposition of anthropogenic nitrogen (N) transported from areas of human activity (fuel combustion, agriculture) may affect these natural habitats if it exceeds an ecosystem-dependent critical load (CL). We quantify and interpret the deposition to Class I US national parks for present-day and future (2050) conditions using the GEOS-Chem global chemical transport model with 1/2 degrees x 2/3 degrees horizontal resolution over North America. We estimate CL values in the range 2.5-5 kg N ha(-1) yr(-1) for the different parks to protect the most sensitive ecosystem receptors. For present-day conditions, we find 24 out of 45 parks to be in CL exceedance and 14 more to be marginally so. Many of these are in remote areas of the West. Most (40-85 %) of the deposition originates from NOx emissions (fuel combustion). We project future changes in N deposition using representative concentration pathway (RCP) anthropogenic emission scenarios for 2050. These feature 52-73% declines in US NOx emissions relative to present but 19-50% increases in US ammonia (NH3) emissions. Nitrogen deposition at US national parks then becomes dominated by domestic NH3 emissions. While deposition decreases in the East relative to present, there is little progress in the West and increases in some regions. We find that 17-25 US national parks will have CL exceedances in 2050 based on the RCP8.5 and RCP2.6 scenarios. Even in total absence of anthropogenic NOx emissions, 14-18 parks would still have a CL exceedance. Returning all parks to N deposition below CL by 2050 would require at least a 50% decrease in US anthropogenic NH3 emissions relative to RCP-projected 2050 levels. C1 [Ellis, R. A.; Jacob, D.

Electron microscopy indicated better adhesion between WF particles and PCL than between MCC particles and PCL. Neither wood flour nor MCC cellulose appeared to significantly affect the crystallinity of PCL. Environmental conditioning resulted in only minor deterioration of mechanical properties, although samples soaked in water had greater deterioration of mechanical properties than those in high humidity or freezing environments. After a modified 12-week soil block test, specimens made with wood flour lost weight and showed signs of decay after exposure to the brown-rot fungus Gloeophyllum trabeum.

Composites of high-density polyethylene in pellet form (HDPE), 25% by weight of PW, and either 0% or 5% by weight of maleated polyethylene pellets (MAPE), were produced by twin screw compounding followed by injection molding. Formulations of PW flour composed of specific particle sizes (<= 590 to <= 75 mu m) were also compared. Molded test composites were evaluated for their tensile, flexural, impact, and thermal properties. Composites made with PW and MAPE had significantly improved tensile and flexural properties compared to neat HDPE. The impact strength of all composites using MAPE was 30% improved over HDPE. Benchmarking PW composites to similar preparations of pine wood flour composites demonstrated that PW can produce a comparable and in some cases a superior bio-fiber composite. The effect of environmental exposure was examined by soaking tensile bars of HDPE-PW blends in distilled water for 28 days to observe changes in their physical and mechanical properties. Finally, differential scanning calorimetery and thermogravimetric analysis were conducted on PW composites to evaluate their thermal properties and the implications these may have on selecting processing conditions for the bio-fiber reinforcements.

An acid-free ethanosolv process was proposed to overcome the problems caused by the acid catalysts commonly used in organosolv processes. In this research, ethanosolv pretreatment catalyzed by NaOH was used to enhance the enzymatic saccharification of moso bamboo. The addition of 10% (w/w on bamboo) NaOH in 75% (v/v) ethanol was demonstrated to be effective in the pretreatment and fractionation of bamboo. The pretreatment yielded a solid fraction with 60.1% cellulose. The cellulose-to-glucose conversion yield was 28.9% to 45.1%, depending on pretreatment conditions, after enzymatic hydrolysis of the solid fraction at 50 degrees C for 48 h using enzyme loading (15 filter paper units of cellulase/g cellulose and 30 IU beta-glucosidase/g cellulose). The concentrations of fermentation inhibitors such as 5-hydroxy-2-methyl furfural (HMF) and furfural were negligible in the spent liquor after the ethanosolv pretreatment and were much lower than those in the spent liquor from H2SO4-water or ethanosolv only treatment.

CA LIFE Study Investigator Grp TI Promoting physical activity for elders with compromised function: the Lifestyle Interventions and Independence for Elders (LIFE) Study physical activity intervention SO CLINICAL INTERVENTIONS IN AGING LA English DT Article DE aging; accelerometry; physical disability; compromised physical function; older adults ID POOR CARDIOVASCULAR HEALTH; OLDER-ADULTS; WEIGHT-LOSS; KNEE OSTEOARTHRITIS; OBESE; DISABILITY; PERFORMANCE; EXERCISE; MOBILITY AB The Lifestyle Interventions and Independence for Elders (LIFE) Study is a Phase III randomized controlled clinical trial (Clinicaltrials.gov identifier: NCT01072500) that will provide definitive evidence regarding the effect of physical activity (PA) on major mobility disability in older adults (70-89 years old) who have compromised physical function. This paper describes the methods employed in the delivery of the LIFE Study PA intervention, providing insight into how we promoted adherence and monitored the fidelity of treatment. Data are presented on participants' motives and self-perceptions at the onset of the trial along with accelerometry data on patterns of PA during exercise training. Prior to the onset of training, 31.4% of participants noted slight conflict with being able to meet the demands of the program and 6.4% indicated that the degree of conflict would be moderate. Accelerometry data collected during PA training revealed that the average intensity - 1,555 counts/minute for men and 1,237 counts/minute for women - was well below the cutoff point used to classify exercise as being of moderate intensity or higher for adults. Also, a sizable subgroup required one or more rest stops. These data illustrate that it is not feasible to have a single exercise prescription for older adults with compromised function. Moreover, the concept of what constitutes "moderate" exercise or an appropriate volume of work is dictated by the physical capacities of each individual and the level of comfort/stability in actually executing a specific prescription.

By combining expression profiling and virus induced gene silencing (VIGS), we are developing a genetic framework for Rpp4-mediated resistance. We measured gene expression in mock-inoculated and P. pachyrhizi-infected leaves of resistant soybean accession PI459025B (Rpp4) and the susceptible cultivar (Williams 82) across a 12-day time course. Unexpectedly, two biphasic responses were identified. In the incompatible reaction, genes induced at 12 h after infection (hai) were not differentially expressed at 24 hai, but were induced at 72 hai. In contrast, genes repressed at 12 hai were not differentially expressed from 24 to 144 hai, but were repressed 216 hai and later. To differentiate between basal and resistance-gene (R-gene) mediated defence responses, we compared gene expression in Rpp4-silenced and empty vector-treated PI459025B plants 14 days after infection (dai) with P. pachyrhizi. This identified genes, including transcription factors, whose differential expression is dependent upon Rpp4. To identify differentially expressed genes conserved across multiple P. pachyrhizi resistance pathways, Rpp4 expression datasets were compared with microarray data previously generated for Rpp2 and Rpp3-mediated defence responses. Fourteen transcription factors common to all resistant and susceptible responses were identified, as well as fourteen transcription factors unique to R-gene-mediated resistance responses. These genes are targets for future P. pachyrhizi resistance research. C1 [Morales, Aguida M. A. P.; Borem, Aluizio] Univ Fed Vicosa, Dept Fitotecnia, BR-36570000 Vicosa, MG, Brazil.

The polyphenol epigallocatechin gallate (EGCG), an analogue of a compound found in nematode cysts, reduced hatch from both Heterodera glycines and Meloidogyne incognita eggs. Reduction was by 22.7% in H. glycines and 68.5% in M. incognita at 14 days after exposure to 1.0 mM EGCG. Significant reductions in hatch were observed at 7 days after exposure in H. glycines eggs, and as early as 5 days in M. incognita. Half-maximal percentage hatch was delayed by 0.6 days in H. glycines and 1.1 days in M. incognita (16.2 and 18.3%, respectively). Decreased hatch was associated primarily with an increase in unhatched, but viable, second-stage juveniles (J2). Hatch levels could be completely restored by day 14 in both species if EGCG was replaced with water on day 3. Replacement on day 7 partially restored hatch in M. incognita but was not effective in H. glycines. Inhibition of chitinase activity by EGCG suggests one factor in J2 retention in the egg. Exposure to low temperature decreased hatch by ca 50% in both species but without accumulation of unhatched J2. This stage peaked on day 3 in H. glycines-treated eggs, and on day 7 in M. incognita. However, response to low temperature in each species was characterised by developmental arrest at the first-stage juvenile.

These metrics can include a reduction in the percentage of fine drops, measured spray drift from a field trial, or computer modeling of spray drift based on the application system and the droplet spectrum resulting from the specified operational conditions. The percentage of the spray volume constituted by droplets with diameters of less than 141 mu ml provided the most consistent and robust separation of droplet sizes and drift potential across all the nozzle, adjuvant, and active ingredient combinations tested. This study illustrates that adjuvants alter the spray distribution in different ways for different spray nozzles. The oil concentrate in this study uniformly narrowed the entire spray distribution, whereas in contrast the polymers widened the spray distribution because there was a greater increase in the spray volume made up of large droplets and only a modest increase in the spray volume made up of smaller droplets. When evaluating different spray technologies, it is critical that one consider the overall spray distribution and use it as a comparative measure of multiple technologies, particularly with active formulations and spray solution modifiers.

Twelve spray-solution treatments were evaluated, ten of which contained a formulated glyphosate product and nine of these contained an additional tank-mix adjuvant. Droplet-size testing was conducted across multiple operational points (nozzle-orifice size, nozzle orientation, spray pressure, and airspeed), in a high-speed wind tunnel, which corresponds to the response surface experimental model used to develop the present spray-nozzle models. The hypothesis that the different treatment solutions would respond linearly across a range of operational parameters and that a correction factor from relative to water plus non-ionic surfactant solution was proven false. When compared to water or the water plus non-ionic surfactant, the changes in atomization across the operation spectrum of the nozzle were not consistent and varied by formulation. Attempts to apply regression fits for a correction factor based on solution physical properties were not successful. With the formulated glyphosate tank mix used, none of the adjuvants tested, except the polymer, showed significant changes in droplet size under the high air shear regime. Whereas there is likely a need to develop formulated product-specific atomization models, the further addition of adjuvants do not significantly change the atomization characteristics, and, as such, should not require a unique spray-nozzle model.

High speed wind tunnel testing was conducted to determine droplet size resulting from treatments selected for evaluation in the field. These treatments included a "blank" (water plus a non-ionic surfactant) as well as five additional solutions with a formulated fungicide, four of which have an additional adjuvant. The wind tunnel testing measured droplet size using the flat fan nozzles and operational parameters (spray pressure, nozzle orientation, and airspeed) selected for field trials. These treatments were then evaluated in the field for both in-swath and downwind deposition, with a mass balance on the measured results used to compare each of the formulated product treatments to a reference treatment. Wind tunnel results showed the formulated product tank mixes resulted in significantly different droplet sizes than the water and non-ionic surfactant "blank" reference sprays. Additional adjuvants resulted in minimal changes in droplet size as compared to the formulated product mixture. However the polymer tested broadened the droplet size distribution. Drift modeling of the wind tunnel droplet size results demonstrated little difference between the formulated product and spray adjuvant spray mixtures. However, all treatment solutions significantly reduced modeled drift as compared to the reference treatment. While the field study results did highlight significant differences between treatments solutions, it also showed a great degree in data variability as a result of meteorological and sampling issues. These results have led the authors to conclude that field testing of potential drift reduction technologies under aerial application conditions will be cost prohibitive and likely would give highly variable results. Wind tunnel evaluations at certified laboratories offer a much quicker and inexpensive method for evaluating large numbers of nozzle and spray formulation treatments.

Synthetic hexaploid wheat (SHW) genotypes recreated from its two progenitor species, the tetraploid, Triticum turgidum (2n = 4x = 28, AABB) and its diploid wild relative, Aegilops tauschii (2n = 2x = 14, DD) are a useful resource of new genes for hexaploid wheat improvement. These include many productivity traits such as abiotic (drought, heat, salinity/sodicity, and waterlogging) and biotic (rusts, septoria, barley yellow dwarf virus (BYDV), crown rot, tan spot, spot blotch, nematodes, powdery mildew, and fusarium head blight) stress resistance/tolerances as well as novel grain quality traits. Numerous SHWs have been produced globally by various institutions including CIMMYT-Mexico, ICARDA-Syria, Department of Primary Industries (DPI), Victoria-Australia, IPK-Germany, Kyoto University-Japan, and USDA-ARS. This review examines the varied aspects in the utilization of synthetics for wheat improvement including the traits and genes identified, mapped, and transferred to common wheat. It has also been demonstrated that synthetic back-cross-derived lines (SBLs, i.e., when SHW is crossed to adapted local bread varieties) show significant yield increases and thus, enhanced yield performance across a diverse range of environments, demonstrating their potential for improving wheat productivity worldwide. This is particularly evident in moisture-limited environments. The use of SBLs, advanced backcross QTL analysis, chromosome introgression lines, and whole genome association mapping is contributing to the elucidation of the genetic architecture of some of the traits. The contribution of transgressive segregation to enhanced phenotypes and the mechanisms including its genetic and physiological basis are yet to be elucidated. Understanding these would further enhance the utility of SBLs. Considerable progress has been made in the identification of useful quantitative trait loci (QTL) and genes, however the transfer of such rich genetic diversity into elite wheat cultivars is still quite limited. Gaps still exist in data cataloging; and access to such information could serve as an important community resource. Future production of new SHW should extend to under-exploited AB genome tetraploids such as T. turgidum ssp. carthlicum, T. turgidum ssp. dicoccum, and T. turgidum ssp. dicoccoides and identifying gaps in the Ae. tauschii germplasm used for existing SHW. Identifying geographical areas where the progenitor species of the existing SHW were collected would assist in guiding future collection missions. The recent advances in molecular technologies with whole genome sequencing becoming affordable will provide researchers with opportunities for more detailed analysis of traits and the deployment of more efficient strategies in the use of the unique exotic alleles derived from SHW for common wheat improvement. Thus, the contribution of SHW and the derived SBLs to wheat cropping systems worldwide is likely to grow in significance. However, these potential benefits are only realizable if phenotyping is equally extensive and effective. C1 [Ogbonnaya, Francis C.; Abdalla, Osman] ICARDA, Aleppo, Syria.

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

AB Glycinebetaine (GB) and humic acid (HA) are 2 commercial growth regulators that are being used worldwide to enhance the tolerance of most crops, including fruit trees, to various stresses, including drought stress (DS). Malus robusta Rehder is considered as one of the most important rootstocks for apple in China, but its growth and productivity is believed to be adversely affected by DS. The effects of different concentrations and combinations of GB (0, 100, and 200 mg L-1) and HA (0, 500, 1000, and 1500 mg L-1) on M. robusta seedling growth, photosynthesis characteristics, osmolyte accumulation, and antioxidant responses were evaluated under DS and non-DS conditions. GB and HA applied exogenously to drought-stressed M. robusta seedlings increased total dry matter, net photosynthetic rate, free proline content, endogenous glycinebetaine content, soluble sugar content, and potassium content as well as the activities of superoxide dismutase, peroxidase, and catalase. However, GB and HA decreased stomatal conductance and malondialdehyde content. The above-mentioned responses were greater for combined application of GB and HA as compared to application of only GB or HA. The best responses for most of the above parameters were with the application of 100 mg L-1 GB and 1500 mg L-1 HA. These results suggest that application of GB and HA could mitigate the deleterious effects of DS on Malus seedlings and offer an efficient, economical, and simple means to enhance DS tolerance of the apple rootstock.

Additionally, many green jobs training programs are intended to provide pathways out of poverty for low-skilled workers. In this case study, we analyze the experiences of graduates from a New York City, USA green jobs training program targeting 18-24 year olds previously disconnected from the workforce as they transition to full-time employment. Graduates of the program work directly in arboriculture, ecological restoration, landscape design, and horticulture. Despite the well-documented benefits of nature on individual socio-psychological well-being, scant research has investigated the effects of working professionally in urban natural resources management. Our findings reveal the significant challenges facing training program graduates and their supervisors, but also the benefits of urban conservation job training and employment that are potentially transformational for these economically disadvantaged young adults. Green job training and employment present real opportunities for intellectual stimulation and an increased sense of accomplishment, due in part to the uniqueness of environmental work. Individuals reported positive environmental attitudes and behaviors as a result of green jobs training and employment. Published by Elsevier GmbH.

AB The National Clonal Germplasm Repository in Davis, CA is a United States Department of Agriculture (USDA), Agricultural Research Service (ARS) genebank that houses national collections of various Mediterranean fruit and nut crops. The Prunus collection is the second largest in this genebank and is exceeded only by Vitis (grapes). There are more than 90 taxa and in excess of 1600 accessions of Prunus spp. in the collection that includes almonds, apricots, cherries, peaches, and plums. The mission of the genebank is to acquire, maintain, evaluate, and distribute germplasm. Acquisition is from plant collection trips and donations of germplasm to the repository and includes cultivars, breeding lines, and Prunus wild relatives. The trees are propagated and maintained in the Wolfskill Experimental Orchard near Winters, CA and in containers in screen houses in Davis. Evaluation data are compiled on phenotype and genotype and are freely available online at the Germplasm Resources Information Network (GRIN), see: http://www.ars-grin.gov/cgi-bin/npgs/html/site_holding.pl?DAV. As a part of genetic characterization of germplasm at the Davis repository, an analysis of genetic diversity and differentiation using fifteen SSR loci among five diploid Prunus spp. revealed significant variability within and among species with a number of species specific alleles of low to moderate frequencies. The average number alleles/locus across the 15 loci assayed ranged from 6.93 for peach (P. persica) to 18.27 for almond (P. dulcis) with an overall average of 11.38 alleles/locus. Among the cultivated species, the observed and expected heterozygosities were relatively higher except for P. persica with 0.3247 and 0.4351 for observed and expected levels, respectively and with the lowest average number of alleles across loci (6.93) among the cultivated species. Within population genetic variability measures indicated that P. dulcis is the most highly variable species among the cultivated Prunus followed by P. ceracifera, P. armeniaca and P. salicina. As expected, peach and almond showed close genetic affinity followed by diploid plums, and apricots. The results are summarized as applied to genetic conservation, management, and utilization of Prunus germplasm. C1 [Preece, J.

It and a subsequent release 'Conquest' were not commercially successful and can no longer be found. In a quest to understand stone formation, germplasm was obtained from California and Oregon that is likely related to Burbank's stoneless germplasm. Our initial experiments suggested that this material is stoneless because fewer cells are present that would form the endocarp which is the tissue that hardens into the stone. In a selection called 'Stoneless', an empty space around the seed is evident where the stone would normally be found. Our observations confirmed Burbank's that in 'Stoneless' the stone is not completely absent but contains at minimum a sliver of stone along the suture region that is part of the finiculus. The amount of stone tissue appears to be related to climate and may vary between years from nearly stoneless to containing a complete, intact stone. We have begun to analyze the differences in stone development just prior to pollination until about 10 days after pollination when we can observe differentiation of the endocarp. Using techniques such as real-time PCR and RNA sequencing to measure gene expression we have identified a number of candidate genes that may be involved with stone development. C1 [Callahan, A.

Meeting these challenges will require innovation in many areas of science and technology and especially in plum breeding. In an effort to develop new approaches to plum improvement the USDA-ARS Appalachian Fruit Research Station fruit breeding program in collaboration with partners in the U. S. and Europe have developed a genetic engineering (GE) approach to target resistance to Plum pox virus (PPV) the causal agent of sharka, one of the most destructive diseases of plum. This program has resulted in the development of a GE plum cultivar 'HoneySweet' which has been tested for 15 years in the European Union and in the U. S. and is highly resistant to PPV. 'HoneySweet' has received full regulatory approval in the U. S. 'HoneySweet' represents a new source of PPV resistance for growers and it can be used by breeders to develop additional resistant cultivars and/or rootstocks. Rapidly incorporating important traits into improved plum cultivars requires new approaches to breeding that can reduce or eliminate breeding limitations such as long juvenility periods; the need for extensive and costly breeding plots; and yearly limitations on flowering and fruiting related to seasonal dormancy. To address these limitations the USDA group and partners in the U. S. have developed a system to shorten the breeding cycle of plum. We have overcome the juvenility and environmental limitations of flowering and fruiting by incorporating a gene that induces trees to flower early and continually. We have reduced the plum generation cycle from 3-7 years to less than one year. We call this rapid breeding system "FasTrack". The system allows for the rapid incorporation of important traits into plums and then in the final generation, when substantial improvements are clearly evident, only seedlings that do not contain the early flowering transgene are selected. The selected trees may then be used directly as new cultivars, or improved lines for further breeding. Genetic engineering of important traits, FasTrack breeding, and other approaches that are under development will allow the latest advances in biology to be applied to improving and sustaining plum production.

The majority of the nutrient data for breakfast cereals in SR are supplied by manufacturers. Nutrient data and ingredients for Kellogg and General Mills ready-to-eat cereals within SR were examined, as those brands represent 62% of the U. S. market. Mean values for total sugar, total dietary fiber, and sodium were calculated for those breakfast cereals within SR releases 18 through 24 (2005-2011). Values from SR18 (n = 120 products) were compared to those from SR24 (n = 151 products t-tests. Sugar levels fell from 27.5 to 24.8 g/100 g and sodium from 511 to 438 mg/100 g, a reduction of 10% (not significant; p = .057) and 14% (p < .05), respectively. Fiber levels rose from 7.1 to 9.4 g/100 g, a 32% increase (p < .05). Nutrient comparisons were made using paired t-tests on a subset of 83 products, which excluded cereals that had been added or dropped between SR18 and SR24. From 2005 to 2011, sugar and sodium levels decreased by 7.6% and 11.2%, respectively, while fiber levels increased by 13.4% (all p < .0001). Whole grain ingredients were found in at least 2/3 of the cereals examined in SR24. Trends observed in this important breakfast category demonstrate positive changes in the nutrient composition which may have an important impact on public health. (C) 2013 Published by Elsevier Ltd.

Flavonoids are secondary metabolites produced by plants in response to various environmental stresses such as climate and ultraviolet radiation. Other sources of variability include cultivar, growing location, agricultural practices, processing techniques and preparation methods, as well as analytical variability. The objective of this manuscript is to examine and report on variability in the flavonoid content of foods. While the required information needed to assess variability is not available for all foods, data for a number of foods was analyzed using analysis of variance for cultivar, location and other factors. For orange juice, data for 247 samples representing 109 mean values, i.e., different cultivars and location, were analyzed. The overall range for hesperetin was 1-39mg/100g; samples from the United States 5-30mg/100g; samples from Brazil 5-25mg/100g; and samples from Corsica (France) 12-26mg/100g. For strawberries, data for 148 samples representing 98 mean values were analyzed. The overall range for pelargonidin was 8-58 mg/100g. The range of quercetin values in raw yellow onions is 0-91mg/100g, and represents 96 mean values for 402 samples from the U. S., Japan, Spain, and other countries. The flavonoid content of foods is extremely variable and is influenced by both location and cultivar, which account for 25 to 33 percent of the variability as well as by numerous other factors, which were not examined in this analysis.

Recent concerns by the U.S. public health community about the intake of sodium by Americans have led ARS, USDA to develop a plan to monitor the levels of sodium in highly consumed commercial packaged and restaurant foods. NDL scientists worked with USDA's Food Surveys Research Group (FSRG) to identify 125 Sentinel Foods, to serve as indicators for assessment of change in the sodium content in the food supply. For each food (e.g., cheese pizza) NDL used market share data to identify the predominant brands and types of foods (e.g., frozen cheese pizza, restaurant pizza) to be monitored for changes in the sodium level over time. Periodically, nutrient values for frequently consumed foods will be updated by chemical analysis or label checks. Estimates will be compared to existing values in the National Nutrient Database for Standard Reference (SR). Since 2010, about 140 foods have been sampled and analyzed by NDL contractors. NDL will continue to generate new sodium data which will be disseminated in the successive releases of the SR. Accurate and current data for sodium in processed foods will support the assessment of changes in sodium in foods as well as the assessment of sodium intake by the U.S. population in the years ahead.

The most recent MPED issued by the Agricultural Research Service (ARS) was Version 2.0, created for use with the National Health and Nutrition Examination Survey (NHANES) 2003-04. Several of the Center for Nutrition Policy and Promotion's (CNPP) projects require food group equivalents data for foods from more recent NHANES. Objective: To provide a supplementary database of food group equivalents for more recent NHANES foods, for use in CNPP projects. Description: Additional foods (n=820) reported in NHANES 2005-06 and 2007-08 were identified for inclusion in several CNPP projects, including the new online diet assessment tool, the SuperTracker. Cup and ounce equivalents were calculated for 750 foods by using the approach described in the documentation for the MPED 2.0. The USDA National Nutrient Database for Standard Reference, Release 23 (2010) was used for calculations. ARS provided equivalents data for 70 formulated foods. The Addendum to the MPED includes cup or ounce equivalents per 100 grams of food for each USDA food group and subgroup, grams of discretionary solid fats and oils, teaspoons of added sugars, alcoholic beverages, as well as whole fruit and fruit juice equivalents. The Addendum database and documentation are available on the CNPP web site at: http://www.cnpp.usda.gov/OtherProjects.htm. Conclusion: The Addendum provides useful data for foods from more recent NHANES that are not in MPED 2.0. It will be available until the next equivalents database is released by ARS.

Pizza is consistently a primary Key Food in the USDA National Food and Nutrient Analysis Program (NFNAP) because it is a contributor of more than 14 nutrients of public health significance to the U. S. diet. The USDA Nutrient Data Laboratory collected national samples of the two leading fast food pizza chains to monitor and update changes in this popular food. Two brands of pizza - cheese (regular, thick, and thin crust) and pepperoni (regular and thick crust) pizzas were collected in 12 nationwide locations in 2003 and again in 2010. Sample units of pizzas were prepared for analysis of proximates, vitamins, minerals and fatty acids using NFNAP protocols. Analytical samples and quality control materials were analyzed by USDA-qualified laboratories using Association of Official Analytical Chemists (AOAC) approved methods. Nutrient data were statistically evaluated (significance set at p<0.05) to compare similar pizzas from different years. Based on these analyses, values for various nutrients changed. For example, both brands of cheese, thin crust pizzas showed a significant increase in sodium (p<0.014). Across all pizza types, brand A pizzas showed a significant increase in iron (p<0.0009-0.036) and potassium (p<0.001-0.013). Total sugars, fiber, cholesterol, and fat values significantly increased or decreased by brand and pizza type. These analyses provide current, accurate, nationally representative data for high consumption foods in the U.S. and are included in the USDA Nutrient Database for Standard Reference 24 as part of an effort to monitor changes in nutrient profiles for popular foods.

The purpose was to obtain analytical nutrient data for three highly consumed fresh pork products in the USDA National Nutrient Database for Standard Reference (SR) and to compare the results to data obtained in 1992. Bone-in baby back ribs (BKR), boneless sirloin roast (SRB), and bone-in blade chops (BCB) were purchased from 12 retail outlets using a nationwide sampling plan developed for. Nutrient values for proximate, cholesterol, and minerals were determined by commercial laboratories using validated methodology including quality control procedures. The 1992 data used for comparison were derived from analyses of samples of raw fresh pork retail cuts which were obtained from supermarkets in 15 cities across the US in a nation-wide market basket study. Nutrient values from 1992 and 2010 for equivalent cuts were statistically evaluated using a paired two-tailed T-test (critical value p<0.05). Comparing 2010 values to 1992 values, moisture was significantly higher (p<0.001) while total fat was lower (p<0.001) in all three cuts. Cholesterol was significantly less in two of the three cuts. Sodium values for 2010 were higher in all three cuts by 7-24% but still below 90 mg/100 g. Phosphorus was higher (p<0.05) in 2010 whereas iron was lower (p<0.001). Values for potassium, calcium, and zinc varied between the two data sets. This research updates the values in SR and provides current and accurate data for use in nutrition monitoring and policy.
