The USDA Automated Multiple-Pass Method (AMPM) uses a five-step multiple-pass approach to collect dietary data. The first step is an unstructured, uninterrupted listing of all foods and beverages consumed. The next 3 steps use a structured approach to data collection including memory cues. The Final Probe step is an unstructured question for any other foods recalled and includes several additional memory cues. The objective of this analysis is to describe patterns of food reporting in the AMPM in a nationally representative sample. This analysis uses data from the 2007-2008 What We Eat in America, National Health and Nutrition Examination Survey for males and females ages 12 and older. The step in the AMPM interview where a food is first recalled and reported is determined and assigned a value. These values are summed to create an AMPM reporting score which reflects the use of the five steps in AMPM in the 24-hour dietary intake recall. There are signficant differences in the AMPM reporting score by day of interview, gender, age and race/ethnicity. The patterns described in this analysis demonstrate the importance of the multiple-pass method in obtaining complete 24-hour dietary recalls. (C) 2013 The Authors. Published by Elsevier Ltd.

Data are supplied by two programs; one program partners with the Department of Health and Human Services to conduct the What We Eat in America portion of the National Health And Nutrition Examination Survey (WWEIA-NHANES); the other program compiles analytical data concerning the composition of food and dietary supplements; it is most recognized for the National Nutrient Database for Standard Reference (SR). Data supplied by these programs are essential for a variety of actions/tasks including regulatory and policy decisions within the U.S. government and scientific publications relating foods and health outcomes; additionally private industry uses the data for varied purposes including assessing demand for certain foods and generating nutrient panels on food labels. Participants at a workshop in Beltsville, MD commented on the state of the programs as well as potential future directions. Participants noted that although the programs are highly regarded by all that use their data, they are in need of changes. However many desired changes are constrained by limited resources. The primary challenge to adequate funding for the programs is maintaining visibility and demonstrating impact, problems that can be addressed in part by proper citations in research articles that use the data and by effective communication of the consequences of insufficient funding.

It provides a user-friendly but powerful interface to help individuals enter food intake, compare it to nutrient goals and the USDA Food Patterns, and track intake over time. At its core, the SuperTracker relies on a food database adapted from ARS's Food and Nutrient Database for Dietary Studies (FNDDS) and MyPyramid Equivalents Database (MPED). Modifications and additions increase the database's convenience for users: Food names were simplified and, in some cases, additional names were assigned; portions and portion descriptions were modified; and MPED values were assigned for foods new to FNDDS 2007-08, to assure that these newer foods were included. SuperTracker is multifunctional, allowing for tiered levels of involvement by users, from looking up a single food to comprehensive dietary and physical activity assessment, goal setting, and planning over time. Features include creation of individualized "combos" and favorite foods, to simplify entry of items consumed often. It provides real-time interactive feedback to users, and offers multiple report options to meet varied user needs. The SuperTracker relies on data from FNDDS and MPED to provide accurate feedback, which enables users to take control of their dietary choices. Monitoring food intake can help individuals become more aware of and improve what they eat and drink. The SuperTracker can empower consumers to track their food intake and activity, in order to improve their health. (C) 2013 The Authors. Published by Elsevier Ltd.

We enhanced an atmospheric inversion of the CO2 flux for North America by introducing spatially explicit information on forest stand age for US and Canada as an additional constraint, since forest carbon dynamics are closely related to time since disturbance. To use stand age information in the inversion, we converted stand age into an age factor, and included the covariances between subcontinental regions in the inversion based on the similarity of the age factors. Our inversion results show that, considering age factors, regions with recently disturbed or old forests are often nudged towards carbon sources, while regions with middle-aged productive forests are shifted towards sinks. This conforms to stand age effects observed in flux networks. At the subcontinental level, our inverted carbon fluxes agree well with continuous estimates of net ecosystem carbon exchange (NEE) upscaled from eddy covariance flux data based on MODIS data. Inverted fluxes with the age constraint exhibit stronger correlation to these upscaled NEE estimates than those inverted without the age constraint. While the carbon flux at the continental and subcontinental scales is predominantly determined by atmospheric CO2 observations, the age constraint is shown to have potential to improve the inversion of the carbon flux distribution among subcontinental regions, especially for regions lacking atmospheric CO2 observations.

Here we use the interferometric synthetic aperture radar (InSAR) technique to compile a benchmark inventory describing the kinematic state of 59 active rock glaciers in this region. In the late summer of 2007, these rock glaciers moved at speeds that range from 14 cmyr(-1) to 87 cmyr(-1), with a regional mean value of 53 cmyr(-1). Our inventory reveals a spatial difference: rock glaciers in the southern Sierra Nevada moved faster than the ones in the central Sierra Nevada. In addition to the regional mapping, we also conduct a case study to measure the surface flow of the Mount Gibbs rock glacier in fine spatial and temporal detail. The InSAR measurements over this target reveal (1) that the spatial pattern of flow is correlated with surface geomorphic features and (2) a significant seasonal variation of flow speed whose peak value was 48 cmyr(-1) in the fall of 2007, more than twice the minimum value observed in the spring of 2008. The seasonal variation lagged air temperatures by three months. Our finding on the seasonal variation of surface speed reinforces the importance of a long time series with high temporal sampling rates to detect possible long-term changes of rock glacier kinematics in a warming climate.

A result of this effort has been the development of 'HoneySweet' plum, a GE cultivar that has proven to be highly resistant to PPV, as demonstrated in over 15 years of study and field testing in the US and Europe. The efficacy and safety of 'HoneySweet' demonstrated in many laboratory, greenhouse and field studies have been validated through the successful regulatory approval of this PPV resistant GE plum cultivar in the US. The international collaborative program that produced 'HoneySweet' demonstrates the potential for publicly-fund research and development to provide safe, efficacious GE products for the benefit of growers and consumers. 'HoneySweet' plum represents a valuable genetic resource for PPV control in the US and in Europe.

The research methods used in virology are therefore equally diverse. This article covers those methods that are very particular to virological research in bees, with numerous cross-referrals to other BEEBOOK papers on more general methods, used in virology as well as other research. At the root of these methods is the realization that viruses at their most primary level inhabit a molecular, subcellular world, which they manipulate and interact with, to produce all higher order phenomena associated with virus infection and disease. Secondly, that viruses operate in an exponential world, while the host operates in a linear world and that much of the understanding and management of viruses hinges on reconciling these fundamental mathematical differences between virus and host. The article concentrates heavily on virus propagation and methods for detection, with minor excursions into surveying, sampling management and background information on the many viruses found in bees.

As part of the BEEBOOK series describing honey bee research methods, we provide standard protocols for studying gut symbionts. We describe non-culture-based approaches based on Next Generation Sequencing (NGS), methodology that has greatly improved our ability to identify the microbial communities associated with honey bees. We also describe Fluorescent In Situ Hybridization (FISH) microscopy, which allows a visual examination of the microenvironments where particular microbes occur. Culturing methods are also described, as they allow the researcher to isolate particular bacteria of interest for further study or gene identification, and enable the assignment of particular functions to particular gut community members. We hope these methods will help others advance the state of knowledge regarding bee gut symbionts and the role they play in honey bee health.

With a genome sequence in hand, and much improved genetic tools, honey bees are now an even more appealing target for answering the major questions of evolutionary biology, population structure, and social organization. At the same time, agricultural incentives to understand how honey bees fall prey to disease, or evade and survive their many pests and pathogens, have pushed for a genetic understanding of individual and social immunity in this species. Below we describe and reference tools for using modern molecular-biology techniques to understand bee behaviour, health, and other aspects of their biology. We focus on DNA and RNA techniques, largely because techniques for assessing bee proteins are covered in detail in Hartfelder et al. (2013). We cover practical needs for bee sampling, transport, and storage, and then discuss a range of current techniques for genetic analysis. We then provide a roadmap for genomic resources and methods for studying bees, followed by specific statistical protocols for population genetics, quantitative genetics, and phylogenetics. Finally, we end with three important tools for predicting gene regulation and function in honey bees: Fluorescence in situ hybridization (FISH), RNA interference (RNAi), and the estimation of chromosomal methylation and its role in epigenetic gene regulation.

In contrast, the beetles can be harmful parasites of European honey bee subspecies. Very rapidly after A. tumida established populations outside of its endemic range, the devastating effect of this beetle under suitable climatic conditions prompted an active research effort to better understand and control this invasive species. Over a decade, A. tumida has spread almost over the entire USA and across the east coast of Australia. Although comparatively few researchers have worked with this organism, a diversity of research methods emerged using sets of diverse techniques to achieve the same goal. The diversity of methods made the results difficult to compare, thus hindering our understanding of this parasite. Here, we provide easy-to-use protocols for the collection, identification, diagnosis, rearing, and for experimental essays of A. tumida. We hope that these methods will be embraced as standards by the community when designing and performing research on A. tumida.

First described from the Western (European) honey bee Apis mellifera L., this mite species was initially observed when honey bee colonies on the Isle of Wight, UK were dying between 1904 and 1919 (Rennie, 1921). Since then, this mite has been found in Europe, North and South America and parts of Asia, but its global distribution is not well understood. In this chapter, we outline protocols for collecting, detecting, identifying, diagnosing and measuring the infestation rates of A. woodi. We also describe methods to determine the damage threshold, outline several control measures, and describe methods for studying live mites.

The synthesis involves the use of the epoxidized form of soybean oil which then undergoes a catalytic ring opening to produce the additive material. Due to their remaining triacylglycerol structure, the products are highly compatible with bio-based lubricants and due to their covalent boron attachments, show effective properties for the reduction of wear. Some performance examples: Using a traditional Fa lex 4-ball wear test, the scar diameter observed in a soybean oil lubricant could be reduced from 0.61 mm to 0.41 mm by the inclusion of 1% or the additive. A second generation additive, while not as effective at reducing wear, was able to increase the oxidation onset temperature of soybean oil under pressurized oxygen by 14 degrees C. Next, these additives were tested in a formulation of biobased gear oil composed of heat treated soybean oil and synthetic esters. In the best formulation, these additives were able to surpass the oxidation onset of a gear oil that was formulated with commercially available additives, while giving nearly as good of performance by wear scar analysis. This oxidation onset value, of 258 degrees C, approaches that of off-the-shelf gear oils. Overall, these new additives are strong performers which can be made using simple chemistry. Their properties combined with their high biobased content are valuable assets in the search for biobased lubricants and gear oils. C1 [Doll, Kenneth M.] NCAUR ARS USDA, Peoria, IL USA.

TI Impact of Line 1 germplasm on South African Hereford cattle SO SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCE LA English DT Article DE Gene flow; migration; relationship ID MULTILOCUS GENOTYPE DATA; POPULATIONS; INFERENCE; BREEDS; MICROSATELLITES; MARKERS AB The goal of this research was to document the influence of Line 1 Hereford cattle, developed by the United States Department of Agriculture at its research facility in Miles City, Montana, on Hereford cattle in South Africa. Analytical approaches made use of both recorded pedigree and microsatellite marker information. Cattle with recorded performance data in South Africa were mated with Line 1 Hereford sires in silico and inbreeding coefficients were calculated for the resulting progeny. The relationship between South African and Line 1 Hereford cattle populations was estimated as twice the maximum inbreeding coefficient for the progeny of each South African animal. The calculated pedigree relationship of Hereford cattle registered in South Africa with Line 1 was 24%. Thirty-six South African Hereford cattle and a sample of 64 Line 1 animals were genotyped with 34 microsatellite markers. Based on a Bayesian model-based clustering method, the probability that the South African Hereford cattle were members of Line 1 was 0.38 +/- 0.08. This research documents one aspect of the far reaching effects of the Line 1 Hereford population. C1 [Leesburg, V. L. R.; MacNeil, M. D.] ARS, USDA, Miles City, MT 59301 USA. [Leesburg, V. L.

The research was aimed to select the optimal wavelengths from Fourier transform near-infrared reflectance (FT-NIR) spectroscopy for the soluble solid content (SSC) evaluation of citrus. A total of 220 Gongchuan citrus were analyzed in this experiment. Standard genetic algorithm, immune genetic algorithm (IGA), and IGA combined with partial least squares projection algorithm (IGA-PLSP) were used for the optimal wavelength selection. The partial least squares (PLS) and least squares support vector machine (LS-SVM) were used for the prediction of SSC. Prediction models using the optimal wavelengths (280 wavelengths) selected by IGA-PLSP significantly improved the prediction results compared with the models using the full spectra. The standard errors of prediction (RMSEP) were reduced by 14.8% and 34.0% for the PLS and LS-SVM model, respectively. In addition, the LS-SVM model based on the IGA-PLSP method achieved better prediction results (correlation coefficient of prediction or R-p = 0.923 and RMSEP 0.66 degrees Brix) compared to the PLS model (R-p = 0.914 and RMSEP = 0.69 degrees Brix). This research demonstrated that the IGA-PLSP algorithm provides an effective means for the optimal wavelength selection, and improves the FT-NIR spectral prediction of citrus SSC.

In addition to volatilizing aboveground biomass and litter layers, forest fires have a profound effect on belowground carbon (C) pools and the cycling of soil organic matter as a whole. However, the influence of fire on belowground organic matter cycling is not well defined and varies widely with fire severity. We measured soil organic matter (SOM) characteristics across a range of fire severities two years after the 2002 Biscuit Fire in southwest Oregon, USA, to address the following questions: (1) Which C pools are preferentially volatilized or transformed to charcoal under low-severity and high-severity fire? (2) How does fire change the distribution of SOM among density fractions and depths? (3) How does fire affect the general character of SOM including such variables as abundance, C:N ratio, C-13 abundance, and C-14 abundance? We examined soils from a mixed hardwood-evergreen forest across a range of burn severities: unburned, low severity, mixed severity, and high severity. Results indicated that increasing burn severity led to progressive loss of forest floor mass, but not to progressive loss of C from the mineral soil. Although fire significantly increased the charcoal content of the soils, fire did not significantly change the distribution of soil organic matter between heavy and free or light fractions. Other significant changes in soil organic matter characteristics included a progressive increase in nitrogen (N) with increasing burn severity, possibly due to the encroachment of N-fixing shrubs following the loss of native vegetation. Although qualitative changes in total root abundance following fire were noted, differences among burn severity treatments were not statistically significant. Increased concentrations of rock fragments in burned areas may be suggestive of erosion in these areas, consistent with previous studies documenting varying degrees of soil erosion following fire. In addition, although C-13 abundances were similar among severely burned and unburned plots, soils from severely burned plots were significantly depleted in C-14 in comparison to soils from unburned plots. This C-14 depletion is most likely the combined result of erosion and preferential combustion of organics enriched in C-14 relative to the bulk soil, perhaps reflecting a historical pattern of fire occurrence and severity across the landscape.

Salvage logging and the treatment combination significantly reduced fuel loadings, fuelbed depth and smoke emissions. Salvage logging and the treatment combination reduced total surface fuel loading (sound plus rotten) by 73 and 77%. All fine woody fuels (<7.6 cm) were significantly reduced by salvage logging and the treatment combination. In contrast, there was significant increase in the 1000-h (7.6-22.9 cm) fuel loading. Salvage logging and the treatment combination reduced mean fuelbed depth by 38 and 65%. Salvage logging reduced PM2.5 emissions by 19%, and the treatment combination reduced emissions by 27%. Salvage logging and the treatment combination reduced PM10 emissions by 19 and 28%. We observed monotonic changes in flame length, reaction intensity and rate-of-spread after salvage logging and treatment combination. Study results illustrate potential differences between the effects of salvage logging after windstorms and the effects of salvage logging after wildfire.

Morgan, Penelope TI The relationship of post-fire white ash cover to surface fuel consumption SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE black char; fire effects; fire severity; fuelbed; prescribed fire ID FIRE; COMBUSTION; FORESTS AB White ash results from the complete combustion of surface fuels, making it a logically simple retrospective indicator of surface fuel consumption. However, the strength of this relationship has been neither tested nor adequately demonstrated with field measurements. We measured surface fuel loads and cover fractions of white ash and four other surface materials (green vegetation, brown non-photosynthetic vegetation, black char and mineral soil) immediately before and after eight prescribed fires in four disparate fuelbed types: boreal forest floor, mixed conifer woody slash, mixed conifer understorey and longleaf pine understorey. We hypothesised that increased white ash cover should correlate significantly to surface fuel consumption. To test this hypothesis, we correlated field measures of surface fuel consumption with field measures of surface cover change. Across all four fuelbed types, we found increased white ash cover to be the only measure of surface cover change that correlated significantly to surface fuel consumption, supporting our hypothesis. We conclude that white ash load calculated from immediate post-fire measurements of white ash cover, depth and density may provide an even more accurate proxy for surface fuel consumption, and furthermore a more physically based indicator of fire severity that could be incorporated into rapid response, retrospective wildfire assessments.

TI Soil heating during burning of forest slash piles and wood piles SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE forest restoration; fuel reduction; pile burning; prescribed fire; soil temperature ID PHYSICAL-PROPERTIES; TEMPERATURES; FLUX; ASH AB Pile burning of conifer slash is a common fuel reduction practice in forests of the western United States that has a direct, yet poorly quantified effect on soil heating. To address this knowledge gap, we measured the heat pulse beneath hand-built piles ranging widely in fuel composition and pile size in sandy-textured soils of the Lake Tahoe Basin. The soil heat pulse depended primarily on fuel composition, not on pile size. Burn piles dominated by large wood produced extreme temperatures in soil profile, with lethal heating lasting up to 3 days. In contrast, the heat pulse was moderate beneath piles containing a mixture of fuel sizes. Considerable spatial variability was noted, as soil temperatures were generally greatest near pile centres and decline sharply toward the pile edges. Also, saturating pile burns with water 8 h after ignition ('mopping up') effectively quenched the soil heat pulse while allowing near-complete fuel consumption. The findings suggest that burning of hand piles will not result in extreme or extensive soil heating except for uncommon conditions when piles are dominated by large wood and occupy a high percentage of the ground surface.

TI Living in a tinderbox: wildfire risk perceptions and mitigating behaviours SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE natural hazard; wildland-urban interface ID WILDLAND-URBAN INTERFACE; HAZARD; HOMEOWNERS; PROGRAMS AB The loss of homes to wildfires is an important issue in the USA and other countries. Yet many homeowners living in fire-prone areas do not undertake mitigating actions, such as clearing vegetation, to decrease the risk of losing their home. To better understand the complexity of wildfire risk-mitigation decisions and the role of perceived risk, we conducted a survey of homeowners in a fire-prone area of the front range of the Rocky Mountains in Colorado. We examine the relationship between perceived wildfire risk ratings and risk-mitigating behaviours in two ways. First, we model wildfire risk-mitigation behaviours as a function of perceived risk. Then, we model wildfire risk-mitigation behaviours and perceived risk simultaneously. The results of the simultaneous model suggest that perceived risk and wildfire risk-mitigating behaviours are jointly determined. By correctly specifying the relationship between risk perceptions and mitigating behaviours, we are better able to understand the relationship between other factors, such as exposure to a wildfire-mitigation program and wildfire risk-mitigating behaviours. We also find that having a wood roof, as well as homeowner age, income and previous experience with living in a fire-prone area, are associated with wildfire risk-mitigating behaviours.

TI The CTR/COPT-dependent copper uptake and SPL7-dependent copper deficiency responses are required for basal cadmium tolerance in A-thaliana SO METALLOMICS LA English DT Article ID P-TYPE ATPASES; ARABIDOPSIS-THALIANA; SUPEROXIDE-DISMUTASE; SACCHAROMYCES-CEREVISIAE; TRANSPORT PROTEIN; MOLECULAR CHARACTERIZATION; METAL ACCUMULATION; OXIDATIVE STRESS; IRON HOMEOSTASIS; PLASMA-MEMBRANE AB Copper (Cu) homeostasis in plants is maintained by at least two mechanisms: (1) the miRNA-dependent reallocation of intracellular Cu among major Cu-enzymes and important energy-related functions; (2) the regulation of the expression of Cu transporters including members of the CTR/COPT family. These events are controlled by the transcription factor SPL7 in Arabidopsis thaliana. Cadmium (Cd), on the other hand, is a non-essential and a highly toxic metal that interferes with homeostasis of essential elements by competing for cellular binding sites. Whether Cd affects Cu homeostasis in plants is unknown. We found that Cd stimulates Cu accumulation in roots of A. thaliana and increases mRNA expression of three plasma membrane-localized Cu uptake transporters, COPT1, COPT2 and COPT6. Further analysis of Cd sensitivity of single and triple copt1copt2copt6 mutants, and transgenic plants ectopically expressing COPT6 suggested that Cu uptake is an essential component of Cd resistance in A. thaliana. Analysis of the contribution of the SPL7-dependent pathway to Cd-induced expression of COPT1, COPT2 and COPT6 showed that it occurs, in part, through mimicking the SPL7-dependent transcriptional Cu deficiency response. This response also involves components of the Cu reallocation system, miRNA398, FSD1, CSD1 and CSD2. Furthermore, seedlings of the spl7-1 mutant accumulate up to 2-fold less Cu in roots than the wild-type, are hypersensitive to Cd, and are more sensitive to Cd than the triple copt1copt2copt6 mutant. Together these data show that exposure to excess Cd triggers SPL7-dependent Cu deficiency responses that include Cu uptake and reallocation that are required for basal Cd tolerance in A. thaliana.

While promotion of successional processes and increased biodiversity may occur without direct interaction between ecosystem engineers and sympatric species, many cases exist where interactions are common. Under such conditions, it is unclear whether direct interactions serve to facilitate or inhibit coexistence of ecosystem engineers and the species attempting to use engineered habitats. We used remote videography within lodges of an ecosystem engineer, beavers (Castor canadensis), to quantify the taxonomic diversity of lodge use by non-beaver fauna and to characterize interactions between beavers and a second engineering species that commonly uses beaver-manipulated habitats, muskrats (Ondatra zibethicus). Beaver lodges were used by eleven types of vertebrates and invertebrates. Although no increased aggression was displayed by resident beavers towards intruding muskrats, the temporally partitioned patterns of muskrats' and beavers' entrances and exits to and from lodges, respectively, and altered behavior among both species during cohabitation, indicates that lodge use by muskrats represents an exploitative behavior as opposed to a mutualistic or even commensalistic relationship. We hypothesize that the ecological similarities between these species promotes competitive interactions, and the observed relationship highlights the tradeoffs faced by ecosystem engineers wherein constructed objects intended to exclude competitors are simultaneously associated with habitat modifications that promote the persistence of those same competitors.

Because of the dynamic and heterogeneous nature of soil, proper incorporation of soil analysis into ecological studies requires knowledge and planning. Unfortunately, many ecologists may not be current (or trained at all) in soil science. We provide this review, based on our cumulative >60 years of work in soil science, to help familiarize researchers with essential information to appropriately incorporate soil analyses into ecological studies. Specifically, we provide a brief introduction into soils and then discuss issues related to soil sterilization, choosing a soil for a greenhouse project, sampling soils, and soil analyses.

In theory, efficient intrachelate energy transfer enhances LSL's sensitivity and specificity. In practice, time-domain measurement effectively rejects short-life spectroscopic interferences. To take full advantage of LSL, a portable luminescence spectrometer was developed and applied to analysis of TC and FQ residues in food matrices. Implementation of light emitting diode excitation and photomultiplier tube gating technique resulted in improved performance especially signal-to-background ratio. Two applications are demonstrated in this work: quantitation of oxytetracycline, the most prominent antibiotic in shrimp aquaculture, with 12.7 ng/g limit of quantification; and binary screening of four FQs registered in European Union in caprine milk: danofloxacin, flumequine, and enrofloxacin plus its metabolite ciprofloxacin at their maximum residue limits at 30, 50, and 100 ng/g, respectively.

Adding whey protein concentrate (WPC80) and cashew pulp (CP) to corn meal, a major ingredient in extruded snacks in the U.S., or whole grains such as barley and quinoa, or cassava, can increase the amount of protein and fiber, and reduce overall carbohydrate content. The products discussed in this study, barley, cassava, corn meal and quinoa were blended with WPC80 (12.5 wt%) or with CP (12.5 wt%), extruded at a terminal melt temperature of 60 C, and fully cooked by baking at 205 C. The extrudates were analyzed for moisture content, glycemic potential, rapidly available glucose (RAG) determined after 20 min, and slowly available glucose (SAG) measured after 120 min, and confocal scanning laser microscopy. The glycemic potential of the different products was dependent on their unique starch properties; adding WPC80 with or without CP added minimal effects. The products' rapidly available glucose values or potential glycemic index were: quinoa (70%), barley (61%), corn (54%), and cassava (48%). Adding WPC80 with or without CP improved the RAG values for barley and quinoa, but not for cassava which increased from 61 to 77%. Adding WPC80 or CP had no effect on corn products. The RAG values were mostly predictive of each product's glycemic potential.

Scanning electron microscopy revealed microstructural transformations indicative of changes in bonding that would be expected if the proteins were extruded. Values for elastic modulus (G') obtained from temperature sweeps from 24 to 70 degrees C showed that solutions of calcium caseinate, egg albumin, and soy protein isolate produced stronger and more ordered networks than solutions of the other three proteins. Activation energies (E-a) calculated from Arrhenius plots were highest for egg albumin, soy protein isolate, and wheat gluten, which undergo sulfhydryl-disulfide bonding when heated; the other proteins produce non-covalent bonds. The strength of protein bonds is determined by G' and information on the types of bonds involved is provided by Ea, enabling predictions to be made about the matrices obtained by processing at elevated temperatures.

For image-based screening, melamine was mixed into dry milk at concentrations (w/w) between 0.2% and 10.0%, and images of the mixtures were analyzed by a spectral information divergence algorithm. Ammonium sulfate, dicyandiamide, and urea were each separately mixed into dry milk at concentrations (w/w) between 0.5% and 5.0%, and an algorithm based on self-modeling mixture analysis was applied to these sample images. The contaminants were successfully detected and the spatial distribution of the contaminants within the sample mixtures was visualized using these algorithms. Liquid milk mixtures were prepared with melamine at concentrations between 0.04% and 0.30%, with ammonium sulfate and with urea at concentrations between 0.1% and 10.0%, and with dicyandiamide at concentrations between 0.1% and 4.0%. Analysis of the Raman spectra from the liquid mixtures showed linear relationships between the Raman intensities and the chemical concentrations. Although further studies are necessary, Raman chemical imaging and spectroscopy show promise for use in detecting and evaluating contaminants in food ingredients.

Although some fluorescence-based automated inspection instrumentation has been developed for food products, there remains a need for devices that can assist on-site inspectors performing visual sanitation inspection of the surfaces of food processing/handling equipment. This paper reports the development of an inexpensive handheld imaging device designed to visualize fluorescence emissions and intended to help detect the presence of fecal contaminants, organic residues, and bacterial biofilms at multispectral fluorescence emission bands. The device consists of a miniature camera, multispectral (interference) filters, and high power LED illumination. With WiFi communication, live inspection images from the device can be displayed on smartphone or tablet devices. This imaging device could be a useful tool for assessing the effectiveness of sanitation procedures and for helping processors to minimize food safety risks or determine potential problem areas. This paper presents the design and development including evaluation and optimization of the hardware components of the imaging devices.

This paper reports the development of a hyperspectral imaging technique for detecting and differentiating two of the most common Salmonella serotypes, Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST), from background microflora that are often found in poultry carcass rinse. Presumptive positive screening of colonies with a traditional direct plating method is a labor intensive and time consuming task. Thus, this paper is concerned with the detection of differences in spectral characteristics among the pure SE, ST, and background microflora grown on brilliant green sulfa (BGS) and xylose lysine tergitol 4 (XLT4) agar media with a spread plating technique. Visible near-infrared hyperspectral imaging, providing the spectral and spatial information unique to each microorganism, was utilized to differentiate SE and ST from the background microflora. A total of 10 classification models, including five machine learning algorithms, each without and with principal component analysis (PCA), were validated and compared to find the best model in classification accuracy. The five machine learning (classification) algorithms used in this study were Mahalanobis distance (MD), k-nearest neighbor (kNN), linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), and support vector machine (SVM). The average classification accuracy of all 10 models on a calibration (or training) set of the pure cultures on BGS agar plates was 98% (Kappa coefficient = 0.95) in determining the presence of SE and/or ST although it was difficult to differentiate between SE and ST. The average classification accuracy of all 10 models on a training set for ST detection on XLT4 agar was over 99% (Kappa coefficient = 0.99) although SE colonies on XLT4 agar were difficult to differentiate from background microflora. The average classification accuracy of all 10 models on a validation set of chicken carcass rinses spiked with SE or ST and incubated on BGS agar plates was 94.45% and 83.73%, without and with PCA for classification, respectively. The best-performing classification model on the validation set was QDA without PCA by achieving the classification accuracy of 98.65% (Kappa coefficient=0.98). The overall best performing classification model regardless of using PCA was MD with the classification accuracy of 94.84% (Kappa coefficient=0.88) on the validation set.

Fresh bovine feces were applied to the surfaces of washed loose baby spinach leaves. A hyperspectral line-scan imaging system was used to acquire hyperspectral fluorescence images of the contaminated leaves. Hyperspectral image analysis resulted in the selection of the 666 nm and 688 nm wavebands for a multispectral algorithm to rapidly detect feces on leafy greens, by use of the ratio of fluorescence intensities measured at those two wavebands (666 nm over 688 nm). The algorithm successfully distinguished most of the lowly diluted fecal spots (0.05 g feces/ml water and 0.025 g feces/ml water) and some of the highly diluted spots (0.0125 g feces/ml water and 0.00625 g feces/ml water) from the clean spinach leaves. The results showed the potential of the multispectral algorithm with line-scan imaging system for application to automated food processing lines for food safety inspection of leafy green vegetables.

In addition to being a well-established food ingredient, peanut flour is also the active ingredient in peanut oral immunotherapy trials. Enzymatic hydrolysis was evaluated as a processing strategy to generate hydrolysates from peanut flour with reduced allergenicity. Methods: Soluble fractions of 10% (w/v) light roasted peanut flour dispersions were hydrolyzed with the following proteases: Alcalase (pH 8.0, 60 degrees C), pepsin (pH 2.0, 37 degrees C) or Flavourzyme (pH 7.0, 50 degrees C) for 60 min. Western blotting, inhibition ELISA and basophil activation tests were used to examine IgE reactivity. Results: Western blotting experiments revealed the hydrolysates retained IgE binding reactivity and these IgE-reactive peptides were primarily Ara h 2 fragments regardless of the protease tested. Inhibition ELISA assays demonstrated that each of the hydrolysates had decreased capacity to bind peanut-specific IgE compared with nonhydrolyzed controls. Basophil activation tests revealed that all hydrolysates were comparable (p > 0.05) to nonhydrolyzed controls in IgE cross-linking capacity. Conclusions: These results indicate that hydrolysis of peanut flour reduced IgE binding capacity; however, IgE cross-linking capacity during hydrolysis was retained, thus suggesting such hydrolysates are not hypoallergenic.

Conservation practices have been tested for their effectiveness in reducing agricultural related pollutants on smaller scales, but farm watershed scale assessments of these practices are limited and few of these have evaluated the impacts on downstream ecology. Several projects focused on oxbow lake watersheds in the Mississippi River alluvial plain were designed to utilize working farms to evaluate primary pollutants in water resources and to identify conservation practices that are most effective in reducing the transport of those pollutants in surface and ground water on a watershed scale. Major findings of these studies include: (1) conservation practices reduced sediment in oxbow lakes, resulting in improved water clarity, plankton growth, and fish stocks; (2) total phosphorus in lakes decreased between 39-50% following application of conservation practices; (3) conservation tillage and cover crops reduced NO3-N losses by 73%, sediment losses by 70; and (4) riparian areas mitigated the transport of sediment in runoff and enhanced the degradation of pesticides.

The North today is in transition, facing increased resource extraction, globalisation of trade and travel, and rapid and accelerating environmental change. This comprehensive review addresses the diversity, distribution, ecology, epidemiology, and significance of nine zoonotic parasites in animal and human populations in the North. Based on a qualitative risk assessment with criteria heavily weighted for human health, these zoonotic parasites are ranked, in the order of decreasing importance, as follows: Echinococcus multilocularis, Toxoplasma gondii, Trichinella and Giardia, Echinococcus granulosus/canadensis and Cryptosporidium, Toxocara, anisakid nematodes, and diphyllobothriid cestodes. Recent and future trends in the importance of these parasites for human health in the North are explored. For example, the incidence of human exposure to endemic helminth zoonoses (e.g. Diphyllobothrium, Trichinella, and Echinococcus) appears to be declining, while water-borne protozoans such as Giardia, Cryptosporidium, and Toxoplasma may be emerging causes of human disease in a warming North. Parasites that undergo temperature-dependent development in the environment (such as Toxoplasma, ascarid and anisakid nematodes, and diphyllobothriid cestodes) will likely undergo accelerated development in endemic areas and temperate-adapted strains/species will move north, resulting in faunal shifts. Food-borne pathogens (e.g. Trichinella, Toxoplasma, anisakid nematodes, and diphyllobothriid cestodes) may be increasingly important as animal products are exported from the North and tourists, workers, and domestic animals enter the North. Finally, key needs are identified to better assess and mitigate risks associated with zoonotic parasites, including enhanced surveillance in animals and people, detection methods, and delivery and evaluation of veterinary and public health services.

TI Combustion efficiency and emission factors for wildfire-season fires in mixed conifer forests of the northern Rocky Mountains, US SO ATMOSPHERIC CHEMISTRY AND PHYSICS LA English DT Article ID BIOMASS-BURNING EMISSIONS; TRANSFORM INFRARED-SPECTROSCOPY; WESTERN UNITED-STATES; FUEL BURNOUT MODEL; TRACE GASES; LABORATORY MEASUREMENTS; PRESCRIBED FIRES; TROPICAL FOREST; AIR-POLLUTION; AIRBORNE AB In the US, wildfires and prescribed burning present significant challenges to air regulatory agencies attempting to achieve and maintain compliance with air quality regulations. Fire emission factors (EF) are essential input for the emission models used to develop wildland fire emission inventories. Most previous studies quantifying wildland fire EF of temperate ecosystems have focused on emissions from prescribed burning conducted outside of the wildfire season. Little information is available on EF for wildfires in temperate forests of the conterminous US. The goal of this work is to provide information on emissions from wildfire-season forest fires in the northern Rocky Mountains, US. In August 2011, we deployed airborne chemistry instruments and sampled emissions over eight days from three wildfires and a prescribed fire that occurred in mixed conifer forests of the northern Rocky Mountains. We measured the combustion efficiency, quantified as the modified combustion efficiency (MCE), and EF for CO2, CO, and CH4. Our study average values for MCE, EFCO2, EFCO, and EFCH4 were 0.883, 1596 g kg(-1), 135 g kg(-1), 7.30 g kg(-1), respectively. Compared with previous field studies of prescribed fires in temperate forests, the fires sampled in our study had significantly lower MCE and EFCO2 and significantly higher EFCO and EFCH4. The fires sampled in this study burned in areas reported to have moderate to heavy components of standing dead trees and down dead wood due to insect activity and previous fire, but fuel consumption data was not available. However, an analysis of MCE and fuel consumption data from 18 prescribed fires reported in the literature indicates that the availability of coarse fuels and conditions favorable for the combustion of these fuels favors low MCE fires. This analysis suggests that fuel composition was an important factor contributing to the low MCE of the fires measured in this study. This study only measured EF for CO2, CO, and CH4; however, we used our study average MCE to provide rough estimates of wildfire-season EF for PM2.5 and four non-methane organic compounds (NMOC) using MCE and EF data reported in the literature. This analysis suggests the EFPM2.5 for wildfires that occur in forests of the northern Rocky Mountains may be significantly larger than those reported for temperate forests in the literature and that used in a recent national emission inventory. If the MCE of the fires sampled in this work are representative of the combustion characteristics of wildfire-season fires in similar forest types across the western US then the use of EF based on prescribed fires may result in an underestimate of wildfire PM2.5 and NMOC emissions. Given the magnitude of biomass consumed by western US wildfires, this may have important implications for the forecasting and management of regional air quality.

In this paper, white spruce (Picea glauca (Moench) Voss) was used to show how the timing of fire relative to seed development may permit non-serotinous species to recolonize burned areas from the aerial seed banks of fire-killed trees. To estimate survival of seeds within closed cones during crown fires, cone heating was simulated using a one-dimensional conduction model implemented in a three-dimensional computational fluid dynamics fire behavior model. To quantify the area burned when germinable seed would be contained within closed cones during a mast year, empirical fire occurrence and seed development (germinability and cone opening) data were compared for multiple locations across the white spruce range. Approximately 12% of cones contained viable seed following crown fire simulations (0.072 ms(-1) mean spread rate; 9147 kWm(-1) mean intensity), and roughly half of the historical area burned resulted from fires that occurred when closed cones would contain germinable seed. Together, these results suggest that non-serotinous species may recolonize burned areas from in situ aerial seed banks, and that this may be an important cause of their existence in fire regimes to which they otherwise seem poorly suited.

Although biosynthesis of the vitamin has been well resolved in recent years, the main research is currently based on Arabidopsis thaliana with very little work done on major crop plants. Here we provide the first report on interactions and expression profiles of PDX genes for vitamin B-6 biosynthesis in potato and how vitamin B-6 content varies in tubers of different genotypes. The results demonstrate that potato is an excellent resource for this vitamin and that strong natural variation in vitamin B-6 content among the tested cultivars indicates high potential to fortify vitamin B-6 nutrition in potato-based foods.

(2000), uses a two source energy balance modelling scheme driven by remotely sensed observations of diurnal changes in land surface temperature (LST) to estimate surface energy fluxes. By using a time-differential temperature measurement as input, the approach reduces model sensitivity to errors in absolute temperature retrieval. The original formulation of the DTD required an early morning LST observation (approximately 1 h after sunrise) when surface fluxes are minimal, limiting application to data provided by geostationary satellites at sub-hourly temporal resolution. The DTD model has been applied primarily during the active growth phase of agricultural crops and rangeland vegetation grasses, and has not been rigorously evaluated during senescence or in forested ecosystems. In this paper we present modifications to the DTD model that enable applications using thermal observations from polar orbiting satellites, such as Terra and Aqua, with day and night overpass times over the area of interest. This allows the application of the DTD model in high latitude regions where large viewing angles preclude the use of geostationary satellites, and also exploits the higher spatial resolution provided by polar orbiting satellites. A method for estimating nocturnal surface fluxes and a scheme for estimating the fraction of green vegetation are developed and evaluated. Modification for green vegetation fraction leads to significantly improved estimation of the heat fluxes from the vegetation canopy during senescence and in forests. When the modified DTD model is run with LST measurements acquired with the Moderate Resolution Imaging Spectroradiometer (MODIS) on board the Terra and Aqua satellites, generally satisfactory agreement with field measurements is obtained for a number of ecosystems in Denmark and the United States. Finally, regional maps of energy fluxes are produced for the Danish Hydrological ObsErvatory (HOBE) in western Denmark, indicating realistic patterns based on land use.

Most wildfires in the north-eastern US occur in the wildland-urban interface, those regions of intermingling urban and non-developed vegetated lands, where access to firefighting resources can be limited. We created monthly wildfire ignition probability maps from environmental predictors and wildfires occurring between 2000 and 2009 for the states of New Jersey, Ohio and Pennsylvania. Predictor variables included a drought index, long-term soil moisture, percentage forest and wildland-urban interface classifications. Probability maps generated from modelled (Maxent) extrapolations were used to create monthly hazard maps to aid agencies and managers with resource allocation and likelihood projections of wildfires across the region. Our results suggest that monthly hazard assessments provide a better indication of potential wildfires than does a single mean annual probability. Our monthly predictions retain information related to long-term seasonal variability associated with environmental variables and the recorded wildfires providing spatial and temporal information for resource allocation.

Recent QTL analysis indicates that some level of physiological resistance exists in individual larvae. We performed a fine mapping analysis to define the genetic interval that confers resistance in the larvae and identify the strongest association molecular markers that could by useful for marker assisted selection of the trait. Evaluation of the interval suggests that only two possible genes (single Ig IL-related receptor-like, XM_003251514.1 and juvenile hormone-binding protein, XM_391872.4) are likely to be responsible for the resistance. Both genes are strong physiological candidates and potentially function as modulators of the antifungal-specific innate immunity pathway in insects.

This contradiction is shown to be a reflection of differences in the bioavailabilities of HMF following different routes of administration. Evidence of contrasting bioavailabilities among different PMFs is shown through comparisons of the pharmacokinetics of nobiletin and tangeretin administered in rats.

Complete cures for these age-associated brain's diseases are still not in sight; therefore delaying or preventing the pathological manifestation of these diseases through enhancing the brain's endogenous defense mechanisms has gained research attention as an alternate approach. Fruits, nuts and vegetables packed with a multitude of phytochemicals, many of which have potent health benefits, are being actively pursued in this alternate approach. Anthocyanins and polyunsaturated fatty acids have been shown to improve brain function by acting as antioxidant or anti-inflammatory agents as well as altering neuronal signaling mechanisms. Walnuts and Amazonian palm fruit (acai), are particularly rich in omega fatty acids and anthocyanins respectively, along with many other neuroactive phytochemicals. A review of the functional effects of walnuts and acai on brain health is presented here.

TI Phytotoxicity assessment for potential biological control of leafy spurge by soilborne microorganisms SO AUSTRALASIAN PLANT PATHOLOGY LA English DT Article DE Bioassay; Cell-free culture filtrates; Deleterious rhizobacteria; Euphorbia esula; Fungal toxins; Phytotoxins ID PLANT-PATHOGENS; RHIZOBACTERIA; EUPHORBIA; WEED; BACTERIA; DISEASE; SOIL AB Leafy spurge (Euphorbia esula-virgata), a native of Eurasia, is a serious invasive weed of western grasslands of North America. It is very difficult and cost-prohibitive to control with herbicides; control by insect biological control agents and cultural practices are minimally effective in suppressing vegetative growth and seed production. Current biological control of leafy spurge with pathogens is primarily with mycoherbicides, which require specific environmental conditions and repeated applications to be effective. Alternative biological control approaches using selected microorganisms to attack roots and adventitious shoots may effectively decrease vigor of leafy spurge without environmental manipulations to ensure control efficacy. Our objectives were to survey leafy spurge accessions and their native soils for associated microorganisms, and to assess these microorganisms for potential biological control. A proposed screening protocol, consisting of primary and secondary assays, effectively detected bacteria and fungi with high phytotoxicity toward leafy spurge. Primary lettuce seedling bioassays indicated that 62 % of rhizosphere and 54 % of endorhizal bacteria significantly (P = 0.05) inhibited root growth, causing necrotic lesions. Over 60 % of fungal isolates bioassayed on rice agar significantly inhibited root growth of lettuce seedlings. The most effective microbial isolates, based on primary bioassays, were screened directly on leafy spurge cuttings in secondary assays. Only intact cells of bacteria were detrimental to leafy spurge, indicating that host-bacterial contact was required for pathogenicity. Culture filtrates of 40 % of the test fungi caused complete chlorosis and leaf wilting. The most effective fungi originated from leafy spurge adventitious shoots. Results of the survey suggest that leafy spurge rhizospheres and adventitious shoots are potential sources of biological control microorganisms, which should be considered for inclusion in comprehensive management programs for leafy spurge.

Selenite adsorption decreased with increasing solution pH. The triple layer model, a chemical surface complexation model, was able to describe selenite adsorption as a function of solution pH by simultaneously optimizing both inner-sphere and outer-sphere selenite surface complexation constants. The fit of the triple layer model to selenite adsorption by soils was much improved over that obtained previously by optimizing solely an inner-sphere selenite surface complexation constant and the protonation constant in the constant capacitance model. In this previous application, the deprotonation constant had been neglected; thereby, preventing the reactive surface hydroxyl group from deprotonating; a chemically unrealistic situation. The selenite surface speciation predicted using the triple layer model was in agreement with that obtained for other strongly adsorbing anions such as molybdate. Direct spectroscopic investigations of selenite surface configuration are needed to corroborate the species predicted by the modeling approach. C1 USDA ARS, US Salin Lab, Riverside, CA 92507 USA.

Recent evidence suggests that agroforestry and grass vegetative filter strips (VFS) may act to mitigate VA transport or enhance VA degradation; however, VAs may adversely affect soil microbial communities within VFS and thus alter the primary functioning of the VFS. The objectives of this research were to investigate potential changes in microbial community structure and function and to quantify the development of antibiotic resistance in VFS and no-till soils exposed to various VA classes and concentrations. Laboratory mesocosms were established using soils collected from no-till cropland and two VFS (grass and agroforestry). Soils were treated with oxytetracycline or lincomycin (5-200 mg kg(-1) soil). Individual mesocosms underwent destructive sampling at nine time points during 63 d, and the soils were tested for soil microbial function (C-utilization, dehydrogenase, and fluorescein diacetate hydrolysis assays), community structure (phospholipid fatty acid analysis), and antibiotic resistance. Functional assays associated with all VA treatments showed an initial inhibitory effect, but this trend was generally reversed by the seventh day. Shifts in microbial community structure and increased antibiotic resistance were not observed, suggesting that the soil microbial communities were robust to the effects of oxytetracycline and lincomycin at test concentrations. This work indicates that using VFS to mitigate VA loss from agroecosystems will not diminish important primary functions associated with VFS use in agriculture.

TI Calibrating Canopy Reflectance Sensors to Predict Optimal Mid-Season Nitrogen Rate for Cotton SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID LEAF NITROGEN; IRRIGATED COTTON; CORN; FERTILIZATION; YIELD; PLANT; VARIABILITY; MANAGEMENT; WHEAT AB Inadequate N supply can limit yield of cotton (Gossypium hirsutum L.), while too much N can cause excessive vegetative growth and delayed maturity. Reflectance sensors offer the potential to diagnose N need and to translate this diagnosis into a variable-rate application of N in real time. Our objective was to calibrate canopy reflectance sensors to predict economically optimal N rate (EONR) in support of variable-rate fertilization. Nitrogen rate experiments were conducted on three soils in 2006 and 2007. Reflectance was measured with three sensors (Crop Circle, GreenSeeker, and Cropscan) at three growth stages (early square, mid-square, and early flower) and at three heights above the canopy (25, 50, and 100 cm). Economically optimal N rate ranged from 0 to 220 kg N ha(-1), suggesting that the need to diagnose EONR is great. Relative reflectance for all three sensors was weakly related to EONR at the early square stage but was related more strongly at the mid-square and early flower stages. Regression equations were not significantly different between mid-square and early flower stages, suggesting that a single equation could be used to translate reflectance measurements to N rates over this period. Relationship to EONR was best for all sensors when placed 50 cm above the canopy. For these stages and height, all three sensors were similarly related to EONR (r(2) = 0.59 to 0.62). These relationships could feasibly support successful variable-rate N applications to cotton.

To test the hypothesis that amendment type is more important than amount, we applied 250 g C m(-2) as manure, legume foliage, wheat (Triticum aestivum L.) residue, municipal biosolid, wood sawdust, brassica (Brassica napus L.) residue, composted wheat residue, sucrose, and cotton linters to both fallow soil and an annual winter wheat crop for five consecutive years. After an additional 3.5 yr with no inputs and all plots being fallow, the SOC of biosolid, manure, and wood amended plots were significantly (P < 0.0001) greater than the unamended check. The application of biosolid increased SOC 492 g m(-2), and manure increased SOC 316 g m(-2), over the fallow check plots in the top 300 kg m(-2) of soil (approximately 0-25 cm). The increase in SOC relative to the check ranged from 0 to 39% of the amendment C applied. The SOC content was 482 g m(-2) greater under continuous winter wheat than under fallow. The amendment and wheat crop effects on soil C and N changed little during the 3.5 yr after treatments ended, indicating that decomposition occurred soon after application. Wood sawdust was unique in that it increased SOC even though it was low in N content, and it changed the soil C/N ratio from 12.3 to 13.4. This field research demonstrated that amendments applied at the same C rate can have variable effects on SOC accretion. C1 [Wuest, Stewart B.; Gollany, Hero T.] USDA ARS, Pendleton, OR 97801 USA.

TI Soil Water Potential Requirement for Germination of Winter Wheat SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID MOISTURE STRESS; VAPOR TRANSPORT; SEED SIZE; TEMPERATURE; EMERGENCE; CONTACT; YIELD; RYE AB In semi-arid climates, seed is often sown into soil with inadequate water for rapid germination. Distinguishing between adequate and marginal water can be difficult. Planting decisions become increasingly complicated when one considers possible differences between cultivars. This study was designed to measure the soil water potential limits for rapid, adequate, and marginal germination of winter wheat (Triticum aestivum L.). Laboratory data showed that germination was rapid (3 to 4 d) in soil at water potentials above -1.1 MPa and slower (4 to 5 d) at water potentials that ranged from -1.1 to -1.6 MPa. Below -1.6 MPa, less than half of the experimental units achieved the cutoff criteria of 75% germination with 5-mm radical length within 25 d. Six cultivars varied in time to germination by an average of 0.34 d, and two randomly selected seed lots of each cultivar differed by an average of 0.20 d. We conclude that variation between seed lots may be as important as variation between cultivars when looking for seed with superior germination under marginal soil water contents.

Although more than 97% of wildlife incidents with U.S. civil aircraft involve birds, damage is more than 4.5 times more likely to occur during a mammal incident (e.g., deer, canids). Bats are the only mammals with the potential to be struck by aircraft outside the airport environment (at least 152.4 m above ground). We examined the Federal Aviation Administration's (FAA) National Wildlife Strike Database from 1990 to 2010 to estimate the frequency of bat incidents with aircraft within the U.S. and the risk relative to other wildlife incidents. We summarized 417 bat incidents with U.S. civil aircraft. There were 10 bat species or species groups involved in these incidents; however, 68.9% were not identified to species. Most (85.7%) bat incidents occurred at Part 139 certificated airports that receive regularly-scheduled passenger flights with more than nine seats or unscheduled flights with more than 30 seats. More incidents occurred during August (28.3%) than any other month. Most bat incidents occurred at night (81.7%), but the greatest incident rate occurred at dusk (57.3%). More incidents occurred during aircraft landing (85.0%) than take-off (11.2%) or other phases of flight (3.7%). 'Minor' damage to aircraft occurred on only two occasions but no damage costs were reported. Incidents coincided with bat behavior, including diel activity, migration, hibernation, and juvenile recruitment. We conclude bat incidents are low risk to U.S. civil aircraft and have minimal economic effect on the U.S. civil aviation industry.

The increase in demand for interior materials has raised concerns regarding combustibility of the materials. The pyrolysis characteristics of fiber, phenolic resin (PF), and nano kaolin-clay (NK) were investigated using thermogravimetry. The fire performances of samples coated with a mixture of NK and PF were determined using a cone calorimeter. The pyrolysis process of fiber included three phases dependent on chemical composition. The initial temperature of PF pyrolysis was about 100 degrees C and it stopped at 280 degrees C. The major mass loss of NK was observed between 400 to 600 degrees C due to the gradual oxolation of the metakaolin. In comparison with fiber board, samples coated with a mixture of NK and PF achieved a better fire performance. The results showed a longer TTI, lower HRR, and THR, and less CO and CO2 yield, especially from a mixture of NK (90%) and PF (10%). The application of an NK and PF mixture to fiber board as a flame retardant is an effective method for enhancing fire safety and resistance.

S. hardwood demand. This study compared and contrasted small and large firms on a number of factors to help determine the unique characteristics of small firms and to provide insights into useful areas for support. Small firms were found to be similar to large firms with respect to the perceived importance attributed to manufacturing capabilities as a business success factor. However, small firms differed substantially from large firms in other ways, such as less attention to information seeking and planned investments. Small firms also tended to make greater use of distribution yards in the hardwood lumber purchasing value chain and requested fewer services from their hardwood lumber suppliers than did larger firms. Small firms were found to be keen on developing their marketing capabilities, including e-commerce, to further their information exchange with customers to successfully produce made-to-order products. Small firms considered the individual characteristics of company owners/managers to be a relatively important success factor to business, more so than larger firms. The results are summarized and discussed through the lens of small firm reliance on niche markets for survival (including fully made-to-order production) and their need to find new revenue during economic downturns.

The principal component analysis indicated that there were significant variations between the hardwood, softwood, and grass lignins due to the differences in syringyl and guaiacyl units as well as the different processing temperatures and times used to isolate the lignins. Partial least squares regression revealed that the concentration of syringyl units was the foremost factor behind the variation in glass transition temperature (T-g) for each lignin sample. It was concluded that structural variations resulting from altering the processing time and temperature and the lignin species directly affect the thermal properties of the lignin. Therefore, by determining the thermal properties of a lignin sample, a basic understanding of its structure can be developed. C1 [Sammons, Rhea J.] Archer Daniels Midland Co, Decatur, IL 62526 USA.

According to GC-MS results, 26 extracts identified in the ethanol/toluene extraction and 17 in the ethanol extraction were found. Heartwood specimens of L. orientalis were highly susceptible to the fungi tested. While 1% NaOH solubility increased 35% in the specimen decayed by T. palustris, only an 8% increase was seen in the specimen exposed to T. versicolor when compared to the control specimen. Decayed wood by T. palustris showed a 5.5% increase in the Klason lignin content when compared to control specimens; however, the Klason lignin content decreased after a T. versicolor attack for 12 weeks. A T. versicolor attack in the cell walls was seen both from the lumina and from the cell corners, and the attack from the cell corners was mainly clear in ray parenchyma cells. An excessive destruction was detected in the wood structure attacked by T. palustris. The cell collapse was caused by a distortion in the plane of the wood cells. This extensive degradation was seen in all types of cell walls. Cracks in the cell walls were also detected in the specimens.

In unglaciated eastern North America, available soil moisture varies greatly along topographic and edaphic gradients. This study was aimed at determining the effects of soil moisture variability and macroclimate on white oak growth in mixed-oak forests of southern Ohio. Using accurately dated and measured tree rings, we analyzed 119 white oaks growing across an integrated moisture index (IMI), a computer-generated GIS model that simultaneously combines topographic and edaphic features into a moisture index scale. Growth trends varied considerably across the IMI, with trees in mesic sites exhibiting patterns much different from those in either xeric or intermediate sites. BAI growth and biomass increments were higher for trees growing in the intermediate and mesic sites than those from the xeric sites. Correlation and response function analyses, and redundancy analysis revealed significant relations between ring-width indices and climate, with current year May-July PDSI, precipitation and temperature as the most important correlates of white oak growth. Additionally, climatic influences on growth rate were variable across the IMI; trees in xeric sites showed much greater coefficients relative to those from the intermediate and mesic sites. Despite these differences, xeric and intermediate trees exhibited similar growth patterns. The present results provide further evidence of the usefulness of the IMI for identifying and comparing white oak growth patterns across the complex, dissected landscape of southern Ohio.

Biocontrol microbes may inhibit or suppress foodborne pathogen growth and enhance existing post-harvest intervention controls. The efficacy of Pseudomonas fluorescens for biocontrol of Escherichia coli O157:H7, a human pathogen, was determined on baby spinach. P. fluorescens strains 2-79, Q287, and Q8R-1 (non-pectolytic and non plant pathogenic) were applied on spinach using the dip inoculation method, prior to inoculation with E. coli O157: H7 strains 43894, 43895, and 35150 individually or as a cocktail mixture. The inoculated spinach was stored at 20 degrees C for 24 and 48 hours, and then evaluated for residual populations of E. coli O157:H7 using Restaino and Frampton E. coli O157:H7 chromogenic medium. In subsequent experiments, the effects of storage time (24 and 48 h) and temperatures (5, 10, 15, 20, 25, and 30 degrees C) on the efficacy of biocontrol were assessed. The reduction of E. coli O157:H7 by P. fluorescens was computed relative to the control. The mean reduction of E. coli O157:H7 by P. fluorescens ranged from 0.5-2.1 log CFU/g of spinach. The efficacy of biocontrol was significantly (P<0.05) affected by storage temperature as suppressive effects were greater at 15 degrees C (1.5-2.4 log CFU/g of spinach) than at other temperatures (<0.93 log CFU/g). As expected, the reduction of E. coli O157:H7 populations varied between storage times of 24 and 48 h. These results imply that when the ratios of biocontrol to pathogen is relatively equal, P. fluorescens could provide low to moderate reductions of E. coli O157:H7 populations on spinach.

Many useful analytical solutions originated in disciplines other than surface-water hydrology, are scattered across the literature, and not always well known. In this two-part series we provide a discussion of the advection-dispersion equation and related models for predicting concentration distributions as a function of time and distance, and compile in one place a large number of analytical solutions. In the current part 1 we present a series of one- and multi-dimensional solutions of the standard equilibrium advection-dispersion equation with and without terms accounting for zero-order production and first-order decay. The solutions may prove useful for simplified analyses of contaminant transport in surface water, and for mathematical verification of more comprehensive numerical transport models. Part 2 provides solutions for advective-dispersive transport with mass exchange into dead zones, diffusion in hyporheic zones, and consecutive decay chain reactions.

To attain this goal antimicrobials have been used in all stages of food animal production in the United States and elsewhere around the world at one time or another. Among food-production animals antimicrobials are used for growth promotion, disease prophylaxis or disease treatment, and are generally administered to the entire flock or herd. Over many decades bacteria have become resistant to multiple antimicrobial classes in a cumulative manner. Bacteria exhibit a number of well characterized mechanisms of resistance to antimicrobials that include: 1) modification of the antimicrobial; 2) alteration of the drug target; 3) decreased access of drug to target; and 4) implementation of an alternative metabolic pathway not affected by the drug. The mechanisms of resistance are complex and depend on the type of bacterium involved (e.g. Gram-positive or Gram-negative) and the class of drug. Some bacterial species have accumulated resistance to nearly all antimicrobial classes due to a combination of intrinsic and acquired processes. This has and will continue to lead to clinical failures of antimicrobial treatment in both human and animal medicine. (C) 2013 PVJ.

Under the standard licensing or permitting process, a manufacturer develops, characterizes, and evaluates a product prior to licensure. The CVB evaluates the submitted information, inspects the manufacturing facilities and methods of production and testing, and confirms key product test results through independent testing. This complete and comprehensive evaluation may not be possible during the emergence of a new animal disease or in response to an introduction of a significant transboundary animal disease agent. Processes are in place in the US that allow for more rapid availability of veterinary products in an emerging or emergency animal health situation. But, it can be advantageous to attain preapproval of products prior to their anticipated need. In this article, issues associated with obtaining approval for use of a biological product under emerging or emergency conditions are discussed. C1 [Hill, R. E., Jr.; Foley, P. L.; Clough, N.

Rift Valley fever (RVF) virus is an important arbovirus that causes lethal disease in cattle, camels, sheep and goats in Sub-Saharan Africa. There is concern that this virus could spread because of global warming, increased animal trade or through bioterrorism. This paper discusses the current and developing approaches to diagnosis of RVF. Diagnostic assays are available for RVF, but availability can be limited and there is a need for global harmonization. Continued improvement of standard serological and viral genome amplification approaches, including new embedded/syndromic testing, biosensor, emerging virus detection and characterization technologies is needed.

Rapid detection and accurate identification of HPAI has been critical to controlling such epizootics in poultry. Specific paradigms for the detection and diagnosis of avian influenza virus (AIV) in poultry vary somewhat among different countries and industry compartments depending on specific needs and resources. Importantly, since HPAI and low pathogenicity (LP) Al of the H5 and H7 subtypes are reportable to the World Organization for Animal Health (OIE), diagnostic procedures are implemented for regulatory purposes and are harmonized to some degree. Most current tests are adequate and have been in use for some time, therefore they have been well validated and presently there is no reported new technology that will completely replace the current tests. However, some modifications, updates or additional tests could be beneficial. The element of AIV diagnostics that is most in need of improvement is in determining the hemagglutinin and neuraminidase subtype specificity of antibody to AIV. Most HPAI epizootics have been eradicated using traditional stamping-out programs, but beginning in 1995, five epizootics have added vaccination as an additional, interim control tool. From 2002-2010, >113 billion doses of Al vaccine have been used in poultry; 95.5% as oil-emulsified, inactivated whole AIV vaccines and 4.5% as live vectored vaccines. The majority of vaccine has been used in the four H5N1 HPAI enzootic countries (China [91%], Egypt [4.7%], Indonesia [2.3%], and Vietnam [1.4%]) where vaccination programs are directed to all poultry. The 10 other countries/regions have used less than 1% of the vaccine, administered in a focused, risk-based approach. Some vaccine "failures" have resulted from antigenic drift of field viruses away from the vaccine viruses, but most have resulted from failures in the vaccination process; i.e. failure to adequately administer the vaccine to at risk poultry resulting in lack of population immunity. China, as the major AIV vaccine user, will drive innovation and commercialization of new vaccine technologies, but because of the low-cost to manufacture the current high quality inactivated whole AIV vaccines, such vaccines will continue to dominate the market for the next 10 years.

Newcastle disease virus (NDV) isolates are also called avian paramyxovirus serotype-1 isolates, but only infection with virulent NDV (vNDV) causes the disease. Virulent Newcastle disease virus (vNDV) isolates are distributed worldwide and have a high capacity to mutate, allowing the development of multiple vNDV genotypes evolving simultaneously at different locations. Large gaps in existing knowledge in the areas of epidemiology and evolution limit the possibilities to control the disease. Recurrent infection of poultry and wild birds allows the maintenance of a reservoir for the viruses; however, the role of wild birds and poultry in vNDV evolution is largely unknown. In the area of diagnostics, the performance of fast and accurate diagnostics methods is often affected by the evolution of viral genomes. Therefore, there is a need for the validation of multiple recently developed experimental tests and a need to develop additional fast and inexpensive diagnostic tests to be used in the field. In the area of vaccination, the development of inexpensive thermostable NDV vaccines and the development of vaccines capable of preventing viral replication are the highest priorities for endemic countries. In countries considered free of vNDV the development of low-cost vaccines that produce minimal vaccine reactions to prevent decreased productivity are higher priorities. Worldwide, better strategies that replace the culling of infected birds are needed to control outbreaks. C1 [Afonso, C.

Loeffler and P. Frosch in 1897, highlighted the need for developing a vaccine against FMD and qualified this as a devastating disease causing "severe economic damage to the country's agriculture" [1]. Inactivated antigen vaccines have been available since the early 1900s and have been instrumental in eradicating FMD from parts of the world and repressing clinical disease in others. However, these vaccines require using live virulent FMDV for manufacturing, fail to prevent infection resulting in the establishment of carrier animals, require multiple vaccination schedules (every six months) and have limited coverage to the specific serotype and in many cases subtype of FMDV. Therefore, FMD vaccinology continues to be a very active research field. Research-based novel vaccine approaches over the last decade have resulted in at least one novel molecular vaccine being licensed for emergency use in the US and multiple other vaccine approaches being actively pursued as alternatives to current vaccines. Here we will review and update the main research efforts on FMD vaccines, including subunit and peptide vaccines, DNA vaccines, empty capsid vaccines (directly delivered or vector delivered), novel inactivated antigen production platforms and live attenuated vaccines. Each of these approaches will be discussed in terms of their safety and efficacy characteristics, product transition feasibility as well as their applicability to global control and eradication efforts.

Methods: Focus groups (N = 30) and pilot testing procedures (N = 17) were used to develop and pretest questionnaire items. Item, reliability, and validity analyses were conducted in a separate sample of 93 youth. Results: The measure was internally consistent (Cronbach alpha = .93) and valid, as evidenced by significant correlations found with construct (diet-specific family support) and criterion (FV consumption) measures. Conclusion: The measure is a promising method for assessing social support for FV consumption in this population. C1 [Di Noia, Jennifer] William Paterson Univ, Dept Sociol, Wayne, NJ 07470 USA.

To address this deficiency, we burned constructed fuelbeds from masticated sites in pine flatwoods forests in northern Florida with palmetto-dominated understoreys and examined the effects of fuel load and fuel moisture content (FMC) on fire behaviour. Flame lengths (49-140 cm) and fireline intensity (183-773 kJ m(-1) s(-1)) increased with loading (10-30 Mg ha(-1)) and were reduced by 40 and 47% with increasing FMC from 9 to 13%. Rate of spread was not influenced by fuel load, but doubled under drier FMC. Fuel consumption was >90% for all burns. Soil temperatures were influenced by both fuel load and FMC, but never reached lethal temperatures (60 degrees C). However, temperatures of thermocouple probes placed at the fuelbed surface reached 274-503 degrees C. Probe maximum temperature and duration at temperatures >= 60 degrees C (9.5-20.0 degrees C min) both increased with fuel load, but were unaffected by FMC. The fire behaviour observed in these unique litter-dominated fuelbeds provides additional insight into the burning characteristics of masticated fuels in general.

Sardinia contains a high density of urban interfaces, recreational values and highly valued agricultural areas that are increasingly being threatened by severe wildfires. Historical fire data and wildfire simulations were used to estimate burn probabilities, flame length and fire size. We examined how these risk factors varied among and within highly valued features located on the island. Estimates of burn probability excluding non-burnable fuels, ranged from 0-1.92 x 10(-3), with a mean value of 6.48 x 10(-5). Spatial patterns in modelled outputs were strongly related to fuel loadings, although topographic and other influences were apparent. Wide variation was observed among the land parcels for all the key values, providing a quantitative approach to inform wildfire risk management activities.

Eco-labels can encourage more sustainable tourism by informing consumers' purchasing decisions, while utilizing market forces to initiate environmental responsibility among competing firms. The Green Coach Certification pilot eco-label program was introduced to the motorcoach industry in 2009 as part of a university research program. Although the literature addresses relationships between end-user consumers and eco-labels, little research has been published on mid-supply chain actors and tourism eco-labels. Tour operators are intermediaries between end-users and motorcoach operators and are important potential consumers of eco-labeled transportation services. To understand the role of tour companies as both consumers and providers of green services and eco-labeled products, a survey was administered to North American tour operators. Results demonstrate tour operator interest in a tourism transportation eco-label; however, this interest may be secondary to traditional considerations like price, reputation for safety and service, and previous partnerships. Ninety percent of tour operators indicated that environmental practices held some importance when choosing a transportation provider; approximately 50% said they would pay between 1% and 5% more for an eco-labeled coach company. Findings have important implications for the design and implementation of eco-labeling programs for sustainable tourism and transportation.

To date, however, the underlying mechanisms that regulate the ecological processes involved are still poorly understood. Three major issues persist in early efforts at resolution. First, in the context that productivity drives species diversity, how the pathways operate is poorly-explained. Second, productivity per se varies with community or ecosystem maturity. If diversity indeed drives productivity, the criterion of choosing appropriate measures for productivity is not available. Third, spatial scaling suggests that sampling based on small-plots may not be suitable for formulating species richness-productivity relationships (SRPRs). Thus, the long-standing assumption simply linking diversity with productivity and pursuing a generalizing pattern may not be robust. We argue that productivity, though defined as 'the rate of biomass production', has been measured in two ways environmental surrogates and biomass production leading to misinterpretations and difficulty in the pursuit of generalizable SRPRs. To tackle these issues, we developed an integrative theoretical paradigm encompassing richer biological and physical contexts and clearly reconciling the major processes of the systems, using proper productivity measures and sampling units. We conclude that loose interpretation and confounding measures of productivity may be the real root of current SRPR inconsistencies and debate.

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

We examined the relationship between common variants in IRS1, type 2 diabetes, and related traits including insulin resistance, hyperglycemia and DNA damage in the Boston Puerto Rican Health Study. Methods: We genotyped six common IRS1 variants in an adult Puerto Rican population (n=1132) and tested for association with risk of type 2 diabetes and related traits. Results: SNPs rs934167 and rs1801123 showed significant association with fasting glucose concentrations (p = 0.005 and p = 0.016, respectively) and rs934167 showed significant association with plasma insulin levels (p = 0.005). Carriers of the rs934167 minor allele had significantly higher HOMA-IR and lower QUICKI (p = 0.001 and p = 0.001, respectively), and a 40% and 58% greater likelihood of being hyperglycaemic or hyperinsulinemic (OR = 1.40 and 1.58; p = 0.013 and 0.002, respectively). However, they exhibited only a marginally significant trend towards having type 2 diabetes (OR=1.27, p = 0.077). Furthermore, carriers of the haplotype C-T of the rs934167 and rs1801123 minor alleles showed consistent patterns of associations after correction for multiple testing. In addition, the G972R (rs1801278) minor allele was significantly associated with higher urinary 8-OHdG concentrations (p = 0.020) and plasma CRP levels (p = 0.035). Conclusions: Our results support IRS1 variants associated with type 2 diabetes risk in adult Puerto Ricans. Moreover, we report the novel finding that IRS1 variant G972R (rs1801278) may contribute to oxidative DNA damage and inflammation.

The molecular species of triacylglycerols containing hydroxy fatty acids (FA) in castor oil have been identified. We report here the identification of twelve diacylglycerols (DAG) containing hydroxy FA in castor oil using positive ion electrospray ionization mass spectrometry of the lithium adducts. They were RR (diricinolein, R is ricinoleate), RL, RS, R-diOH18:0, R-diOH18:1, R-diOH18:2, R-triOH 18:0, R-triOH18:1, R-triOH18:2, diOH18:0-diOH18:1, diOH18:1-diOH18:1 and diOH18:1-diOH18:2. The MS2 fragment ions, [M + Li - FA](+) and [FA + Li](+), from the lithium adducts of DAG containing hydroxy FA (one or two hydroxy FA), were used for the identification. The additional fragment ions from the neutral losses of FA lithium salts [M + Li - FALi](+) were used for the identification of eleven DAG containing two normal FA in a soybean oil bioconversion product. The MS 2 fragment ions from the neutral losses of FA lithium salts [M + Li - FALi](+) were not detected from the DAG containing hydroxy FA. The DAG containing FA with more hydroxyl groups than the other FA on the same DAG molecule tended to have a prominent fragment ion [FA + Li](+) and an undetectable fragment ion [M + Li - FA](+) while the FA was the more hydroxylated FA. Also the less hydroxylated FA of a DAG tended to have a prominent fragment ion [M + Li - FA](+) and an undetectable fragment ion [FA + Li](+) while the FA was the less hydroxylated FA.

After interesterification, the major TAG species in the SL were PLP (22.5 %), PLL/OOLn (21.8 %), LPL (16.1 %), and LLS/PLO (16.1 %), and the total amount of tocopherol and tocotrienol was 20.9 mg/100 g of SL. Sophorolipid was used as an emulsifier for preparing SL-based O/W emulsions, and the effect of pH (pH 5.8, 7 and 7.2) on stability was studied by analyzing the fat globule size. From the results, SL-based O/W emulsions showed similar stabilities to those prepared with Tween 20 at the neutral environment. In the oxidation study, any antioxidant addition of propyl gallate (PG), ascorbic acid 6-palmitate (AP) or quercetin hydrate (Que) distinctively prevented peroxide formation on the SL-based O/W emulsion throughout the 23 days of storage while AP was less effective to lower TBARS values than PG and Que.

Moench ID FUSARIUM; ALTERNARIA; RESISTANCE; SEEDLINGS; SPP.; BIOSYNTHESIS; ASSOCIATION; INFECTION; PATHOGENS; TOXICITY AB Leaves and stalks of many sorghum genotypes accumulate dark red or purple pigments upon wounding while some plants, called tan,' do not. Grains with unpigmented white' pericarps grown on tan plants are more desirable for food. The hypothesis tested was that pigments in plants protected grain against the panicle diseases grain mould and head smut. Near-isogenic tan or purple plant colour genotypes with white grain were planted at Lincoln and Ithaca, NE and Corpus Christi, TX. The field grown grain was plated onto semi-selective media to detect the presence of grain colonisation by mould genera Alternaria, Fusarium and Curvularia. More Fusarium and Curvularia spp. were recovered from grain grown at Corpus Christi than the Nebraska locations; however, there was no indication that the grain from purple plants was more resistant to the three fungal genera. Most fungi were identified morphologically as Alternaria alternata. Molecular identification of Fusarium species, using translation elongation factor 1- gene sequences, showed that Fusarium thapsinum and Fusarium proliferatum infected grain at all three locations. Head smut disease of panicles, caused by the fungus Sporisorium reilianum, was assessed at Corpus Christi; surprisingly, purple plants had significantly greater disease incidence than tan plants. We propose that the tan plant colour lines with white grain are promising for development of food-grade sorghums not more susceptible than pigmented lines to grain mould and head smut.

TI Comparative analysis of tandem repeats from hundreds of species reveals unique insights into centromere evolution SO GENOME BIOLOGY LA English DT Article ID SATELLITE DNA; ALPHA-SATELLITE; CENP-A; HOLOCENTRIC CHROMOSOMES; ARABIDOPSIS-THALIANA; MOLECULAR EVOLUTION; MAIZE KINETOCHORE; YEAST CENTROMERES; SEQUENCES; CHROMATIN AB Background: Centromeres are essential for chromosome segregation, yet their DNA sequences evolve rapidly. In most animals and plants that have been studied, centromeres contain megabase-scale arrays of tandem repeats. Despite their importance, very little is known about the degree to which centromere tandem repeats share common properties between different species across different phyla. We used bioinformatic methods to identify high-copy tandem repeats from 282 species using publicly available genomic sequence and our own data. Results: Our methods are compatible with all current sequencing technologies. Long Pacific Biosciences sequence reads allowed us to find tandem repeat monomers up to 1,419 bp. We assumed that the most abundant tandem repeat is the centromere DNA, which was true for most species whose centromeres have been previously characterized, suggesting this is a general property of genomes. High-copy centromere tandem repeats were found in almost all animal and plant genomes, but repeat monomers were highly variable in sequence composition and length. Furthermore, phylogenetic analysis of sequence homology showed little evidence of sequence conservation beyond approximately 50 million years of divergence. We find that despite an overall lack of sequence conservation, centromere tandem repeats from diverse species showed similar modes of evolution. Conclusions: While centromere position in most eukaryotes is epigenetically determined, our results indicate that tandem repeats are highly prevalent at centromeres of both animal and plant genomes. This suggests a functional role for such repeats, perhaps in promoting concerted evolution of centromere DNA across chromosomes.

The cell line, ARS-PICM-19, was isolated via colony cloning and was found to spontaneously differentiate into hepatic parenchymal epithelial cell types, namely hepatocytes and bile duct cells. Hepatocytes form as monolayers and bile duct cells as 3-dimensional bile ductules. Transmission electron microscopy revealed that the ductules were composed of radially arranged, monociliated cells with their cilia projecting into the lumen of the ductule whereas hepatocytes were arranged in monolayers with lateral canalicular structures containing numerous microvilli and connected by tight junctions and desmosomes. Extensive Golgi and rough endoplasmic reticulum networks were also present, indicative of active protein synthesis. Analysis of conditioned medium by 2-dimensional electrophoresis and mass spectrometry indicated a spectrum of serum-protein secretion by the hepatocytes. The PICM-19 cell line maintains a range of inducible cytochrome P450 activities and, most notably, is the only nontransformed cell line that synthesizes urea in response to ammonia challenge. The PICM-19 cell line has been used for several biomedical-and agricultural-related purposes, such as the in vitro replication of hepatitis E virus, a zoonotic virus of pigs, and a spaceflight experiment to evaluate somatic stem cell differentiation and liver cell function in microgravity. The cell line was also evaluated as a platform for toxicity testing and has been used in a commercial artificial liver rescue device bioreactor. A PICM-19 subclone, PICM-19H, which only differentiates into hepatocytes, was isolated and methods are currently under development to grow PICM-19 cells without feeder cells. Feeder-cell-independent growth will facilitate the study of mesenchymal-parenchymal interactions that influence the divergent differentiation of the PICM-19 cells, enhance our ability to genetically modify the cells, and provide a better model system to investigate porcine hepatic metabolism.

The techniques he developed to isolate and identify cellulose-digesting bacteria from the rumen have had a major impact not only in delineating the complex ecosystem of the rumen but also in clinical microbiology and in the exploration of a number of other anaerobic ecosystems, including the human hindgut. Rumen microbiology has pioneered our understanding of much of microbial ecology and has broadened our knowledge of ecology in general, as well as improved the ability to feed ruminants more efficiently. The discovery of anaerobic fungi as a component of the ruminal flora disproved the central dogma in microbiology that all fungi are aerobic organisms. Further novel interactions between bacterial species such as nutrient cross feeding and interspecies H-2 transfer were first described in ruminal microorganisms. The complexity and diversity present in the rumen make it an ideal testing ground for microbial theories (e. g., the effects of nutrient limitation and excess) and techniques (such as 16S rRNA), which have rewarded the investigators that have used this easily accessed ecosystem to understand larger truths. Our understanding of characteristics of the ruminal microbial population has opened new avenues of microbial ecology, such as the existence of hyperammonia-producing bacteria and how they can be used to improve N efficiency in ruminants. In this review, we examine some of the contributions to science that were first made in the rumen, which have not been recognized in a broader sense. C1 [Krause, D.

In a pilot study, 6 lactating Holstein cows fitted with ruminal cannulae were used in a randomized complete-block design trial. Cows were fed a basal total mixed ration (TMR) containing (DM basis) 15% alfalfa silage, 40% corn silage, 30% rolled high moisture shelled corn, and 14% solvent soybean meal, and assigned to 1 of 3 treatments: 1) control, 2) 160 g/d of LA, or 3) 222 g/d of sodium laurate, which is equi-molar to 160 g/d of LA, all given as a single dose into the rumen via cannulae before feeding. Both agents showed high antiprotozoal activity when pulse dosed at these amounts via ruminal cannulae, reducing protozoa by 90% (P < 0.01) within 2 d of treatment. Lauric acid reduced ruminal ammonia concentration by 60% (P < 0.01) without altering DMI. Both agents reduced ruminal total free AA concentration (P < 0.01) and LA did not affect ruminal pH or total VFA concentration. In a large follow-up feeding trial, 52 Holstein cows (8 with ruminal cannulae) were used in a randomized complete-block design trial. Cows were assigned to 1 of 4 diets and fed only that diet throughout the study. The TMR contained (DM basis) 29% alfalfa silage, 36% corn silage, 14% rolled high moisture shelled corn, and 8% solvent soybean meal. The 4 experimental diets were similar, except part of the finely ground dry corn was replaced with LA in stepwise increments from 0 to 0.97% of dietary DM, which provided (as consumed) 0, 83, 164, and 243 g/d of LA. Adding these amounts of LA to the TMR did not affect DMI, ruminal pH, or other ruminal traits, and milk production. However, LA consumed at 164 and 243 g/d in the TMR reduced the protozoal population by only 25% and 30% (P = 0.05), respectively, showing that these levels, when added to the TMR, were not sufficient to achieve a concentration within the rumen that promoted the antiprotozoal effect of LA.

A report card concept was developed to communicate levels of performance in terms that managers and the public easily understand. Grades were assigned to four aspects of a stable and resilient municipal forest: Species Dominance, Age Structure, Pest Threat and Potential Asset Loss. The data pool of 29 California municipal forest inventories contained information on 836,943 trees. Letter grades (A-F) were assigned to the four criteria and each city received customized recommendations for improving its grades. Three inventories received final grades of As, 18 received Bs, 6 Cs and 2 Ds. Twelve inventories received their highest grade for Species Dominance. Thirteen inventories received their lowest grade for Age Structure, largely because juvenile trees were underrepresented. Pest Threat received the lowest grade in 11 inventories and reduce Pest Threat was the top priority recommendation in 18 inventories. Four multi-host pests posed the greatest risk: Granulate ambrosia beetle, Asian longhorned beetle, Armillaria root rot and red palm weevil. Sycamore/plane was the most vulnerable taxon, followed by oaks, ash and eucalyptus. Eliminating or limiting the use of highly vulnerable tree species was recommended in nearly every city to reduce Pest Threat and improve Species Dominance. Increased planting of vacant sites with species not vulnerable to the most abundant and severe pests was a frequent recommendation for improving Age Structure. Another common recommendation to improve Age Structure was planned removal and replacement of overabundant mature and senescent taxa such as pear, eucalyptus, jacaranda and carrotwood.

In this study, we characterized the composition and content of polyphenolic compounds in the berries of 48 hybrid grapes for two consecutive years. A total of 48 polyphenolic compounds, including 28 anthocyanins, 6 flavanols, 6 flavonols, 2 hydroxybenzoic acids and 6 hydroxycinnamic derivatives, were identified via HPLC-MS and quantified by HPLC-DAD. The content of total polyphenols as well as individual polyphenolic compounds varied significantly among grape hybrids. A number of grape hybrids with high content of total polyphenols and various individual groups of polyphenolic compounds were identified. Principal component analyses identified several polyphenolic compounds, significantly influencing the content variation of total polyphenols and individual groups of polyphenols. Plot analyses on the basis of PC1 and PC2 values provided some interesting insights into the genetic relationships among these grape hybrids. This work is an important addition to our ongoing effort in developing a comprehensive database of nutrition- and health-related secondary metabolites in the Vitis germplasm for future grape improvement.

The nanoparticles were characterized for physicochemical properties by multiple morphological and structural methods (e. g., SEM, TEM, XRD, FTIR, and TPD). The Fischer-Tropsch synthesis (FTS) process was carried out to evaluate the catalytic activity of the nanoparticles on conversion of biomass-derived synthesis gas (bio-syngas) to liquid hydrocarbons. Characterization results revealed that the nanoparticles had core-shell structures with iron in situ encapsulated within a graphitic shell. Moreover, significant amounts of iron carbide (mainly Fe3C) were formed as an interface between the carbonaceous shell and the iron core. FTS tests indicated that such carbon-encapsulated iron nanoparticles possessed a high activity on conversion of bio-syngas and good selectivity towards liquid hydrocarbons (of which olefins were the dominant product). Over a 1500 h testing period, the nanoparticles showed striking stability against deactivation, with CO conversion maintained at about 95% and liquid hydrocarbon selectivity at about 68%.

Putative autapomorphies for Sparganocosma include the extremely short uncus; the smooth (unspined) transtilla; and the upturned, free, distal rod of the sacculus. Adults of Sparganocosma docsturnerorum have been reared numerous times (>50) from larvae collected feeding on rain forest Asplundia utilis (Oerst.) Harling and A. microphylla (Oerst.) Harling (Cyclanthaceae) at intermediate elevations (375-500 m) in ACG. Whereas most Sparganothini are generalists, typically feeding on two or more plant families, Sparganocosma docsturnerorum appears to be a specialist on Asplundia, at least in ACG.

TI Molecular Mapping of the Mutant fap4(A24) Allele for Elevated Palmitate Concentration in Soybean SO CROP SCIENCE LA English DT Article ID SEED OIL; INHERITANCE; GENE; MARKERS; MOTIFS; GENOME AB Soybean [Glycine max (L.) Merr.] oil with an elevated palmitate concentration is useful for some food and industrial applications. The objective of this study was to map the genetic location of the fap4(A24) allele that controls an increase in palmitate concentration and to identify molecular markers that can be used for marker-assisted selection (MAS) of the allele. A cross was made between the mutant line A24(fap4fap4) and the cultivar Archer(Fap4Fap4), and DNA was collected from 22 F-4 plants with normal palmitate and 22 F-4 plants with elevated palmitate concentration. The DNA samples were analyzed on the soybean single nucleotide polymorphism (SNP) chip developed by Monsanto Co. Publicly available simple sequence repeat (SSR) markers were used to fine-map the allele. On the basis of these molecular analyses, the fap4(A24) allele was mapped to chromosome 3 (linkage group N) in an area between SSRs BARCSOYSSR_03_1260 and BARCSOYSSR_03_1313. Seven SSRs and a SNP were identified in the region that perfectly differentiated the plants which were homozygous for the fap4(A24) allele for elevated palmitate or the Fap4 allele for normal palmitate. The public SNP and SSRs should be useful for MAS of the fap4(A24) allele in segregating populations. C1 [Oltmans-Deardorff, Sheilah E.] Monsanto Co, Huxley, IA 50124 USA.

GonaCon (TM) Immunocontraceptive Vaccine is a vaccine used to reduce reproduction in mammalian species, including white-tailed deer (Odocoileus virginianus). The vaccine consists of synthetic gonadotropin releasing hormone (GnRH) conjugated to a mollusk hemocyanin (Concholepas concholepas) prepared as an emulsion with mineral oil to promote a prolonged immune response. Development of an analytical method for determination of the active ingredient in the vaccine formulation was complicated by the emulsion and conjugation of GnRH to the carrier protein. Breaking the emulsion was achieved chemically by addition of diethyl ether. The aqueous portion containing the GnRH conjugate was cleaved enzymatically with a protease (clostripain) at the arginine-proline site of its peptide sequence. Hydrolysis produced a diagnostic eight amino acid peptide fragment which was unique to GnRH and easily quantified by LC/MS/MS. Typical recoveries of fortified samples at the target concentration exceeded 90%.

The central aim of this study was to evaluate the fate of erythromycin in microcosms consisting of pond water and submerged pond sediment. The first study examined the dissipation of erythromycin from spiked water and total recovery of [C-14]-erythromycin from water and sediment within microcosms ranged between 90.1% and 48% throughout the 63-day study. Erythromycin was reduced in surface water of sediment-containing systems by day 7, which corresponded to an increase of eryrthromycin detected in sediment. In the second study the availability of aged erythromycin was evaluated by incubating sediment with and without a manure amendment with [C-14]-erythromycin for 0, 1, 3, or 8 weeks; followed by assessing movement and availability of erythromycin in sediment microcosms after 1, 3, 7, and 14 days. Results indicated differences in residues from aged sediment, with and without manure additions, in extractable residues at day 7 and 14. The addition of manure resulted in greater extractable erythromycin from aged sediments than from sediments without manure. There was a greater release of erythromycin to the water overlying the manure-treated sediments with fresh and 1 week aged sediment than the unamended sediment after 1 and 2 weeks. The results from this experiment demonstrate the ability of manure to influence the fate of erythromycin in environmental matrices.

(Coleoptera: Bostrichidae). The tests were carried out with adult beetles on wheat, maize, and rice. Mortality increased with increasing application rates and exposure intervals for each population. Individually, thiamethoxam alone was more effective at the high dose rate than DE alone, but after 14 days of exposure in most cases, there was greater mortality with DE than with the low dose of thiamethoxam. There was greater mortality in wheat than in rice or maize. Populations differed in susceptibility to treatments and production of progeny. (c) 2012 Elsevier Ltd. All rights reserved.

The goal of this review is to analyze the literature and current use of irradiation to control stored product pests and suggest research to optimize its potential. Doses to prevent reproduction of stored product pests range from 0.05 kGy for Tenebrio molitor L to 0.45 kGy for Sitotroga cereallela (Olivier). Small but increasing amounts of grains and pulses are being irradiated in the world today especially in Asia. At least 33 countries permit irradiation of some stored products with 14 countries permitting it for all stored products. Ways in which stored product irradiation research and application may influence other uses of irradiation technology are also discussed. Deactivation of weed seeds might be an area of stored product phytosanitation where irradiation would have an advantage over other measures. Published by Elsevier Ltd.

Dose response tests were conducted to identify a post-harvest radiation treatment that would control rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae) in rice. Rice infested with adult or immature weevils was treated at radiation doses of 30, 60, 90, or 120 Gy, or left untreated as a control. Live and dead beetles were counted weekly for 15-24 weeks. Treatment of adult weevils at a radiation dose of 120 Gy resulted in no live adults after two weeks, indicating that this radiation dose caused adult mortality and sterility, whereas a total of 1261 adult beetles emerged during 24 weeks in the untreated controls. Treatment of immature life stages (a mixture of eggs, larvae and pupae) with a radiation dose of 90 or 120 Gy resulted in no adults emerging after five or two weeks, respectively, indicating that these doses prevented reproduction, whereas a total of 4275 adults emerged throughout 15 weeks in the untreated controls. Weight loss of rice infested with immature or adult weevils was significantly reduced by irradiation treatment at 60 Gy and 120 Gy. In a large-scale confirmatory test, a radiation dose of 120 Gy applied to 38,025 adult weevils in rice resulted in no reproduction. Irradiation at 120 Gy will provide quarantine security for rice weevil, and prevent post-irradiation weight loss caused by insect feeding in the commodity. Irradiation may be particularly helpful in controlling phosphine-resistant populations, and could help manage resistance by preventing the spread of resistant weevils in exported grains.

Rhyzopertha dominica is an internal feeder during immature stages and presents unique challenges with traditional bioassay methods. Our primary goal was to develop a fast method to evaluate larval development on small amounts of material incorporated homogenously in an artificial diet. Herein we describe a new method that incorporates an artificial diet composed of egg yolk, brewer's yeast, and amylopectin for evaluating the effect of potential biopesticides on the development of R. dominica larvae. Evaluation is accomplished through visual inspection of digital X-ray images, or weighing containers of infested larvae on diet treatments. We demonstrate the method with aprotinin and Bacillus thuringiensis Cry3Aa protoxin, test materials that retard the development of R. dominica larvae. Different bioassay containers were evaluated, including a single larva assay with pipette tips or 8-strip tubes, or a group bioassay in black 16-well trays. In addition to improvements in time and manual manipulations, larvae can now be obtained for biochemical studies by gently washing away the diet. Discrimination of the effect of test materials by weighing the infested containers at specific timepoints was the most simplified approach to rapidly screen test compounds. Published by Elsevier Ltd.

In flour mills the accumulation of residues of flour on surfaces has the potential to influence beetle movement and response to trap attractants. Different flour residue landscapes of habitat (flour) within a matrix of no flour with the following characteristics were created: low abundance (10% coverage) and fragmented distribution, high abundance (30% coverage) and fragmented distribution, low abundance and clumped distribution, high abundance and clumped distribution, 0% coverage, and 100% coverage. Response of individual beetles to traps placed on top of these landscapes was evaluated; traps were either baited with aggregation pheromone and kairomone or contained no attractants. Encounters with the two types of traps were not significantly different for any of the specific landscapes, but greater numbers tended to encounter traps with attractants on fragmented landscapes and 100% flour landscapes. Combining landscape types, the proportion of beetles encountering pheromone + kairomone-baited traps (0.61) was not greater than the proportion encountering empty traps (0.50). However, when combining just the fragmented landscapes there was a significantly greater response to traps with attractants (78%) than traps without (50%), but no difference in response on the combined clumped landscapes. Movement pathways, analyzed using video recordings of beetles, showed a general trend for 0% and 100% habitat landscapes to be most different from each other and 10% and 30% habitat landscapes tended to group together, but only for maximum distance traveled in an interval, velocity, and mean turn angle were significant differences observed. Results suggest that fragmented landscapes may have some impact on beetle response to attractants, but a potential mechanism for this needs further evaluation. Published by Elsevier Ltd.

Donor and public understanding of the economic factors is becoming increasingly central to the longevity of funding for conservation efforts. Unlike typical economic evaluation, many costs and benefits related to conservation efforts are realised in nonmonetary terms. We identify the types of benefits and costs that arise from conservation projects and examine several well developed techniques that economists use to convert benefits and costs into monetary values so they may be compared in a common metric. Costs are typically more readily identifiable than benefits, with financial project costs reported most frequently, and opportunity and damage costs reported much less often. Most current evaluation methods rely primarily on cost-effectiveness analysis rather than cost-benefit analysis, a result of the difficultly in measuring benefits. We highlight improved methodology to measure secondary costs and benefits on a broader spatial scale, thereby promoting project efficacy and long-term success. Estimation of the secondary effects can provide a means to engage a wider audience in discussions of wildlife conservation by illuminating the relevant impacts to income and employment in local economies.

Polymer solutions were characterized by rheometry and tensiometry. Spun fibers were characterized by several analytical steps. SEM analyses showed that both solution blow spun and electrospun fibers had similar morphology. Absence of residual solvents and characteristic infrared bands in the solution blow spun fibers for PLA, PCL, and PEO was confirmed by FTIR studies. XRD diffraction patterns for solution blow spun and electrospun mats revealed some differences related to distinct mechanisms of fiber formation developed by each process. Significant differences in thermal behavior by DSC were observed between cast films of PLA, PCL, and PEO and their corresponding spun nanofibers. Furthermore, the average contact angles for spun PLA and PCL were higher than for electrospun mats, whereas it was slightly lower for PEO. When comparing electrospun and solution blow spun fibers, it was possible to verify that fiber morphology and physical properties depended both on the spinning technique and type of polymer.

However, little is known about the functional regulation of FABP4 at the cellular level in bovine. We designed and selected an effective shRNA (small hairpin RNA) against bovine FABP4, constructed a corresponding adenovirus (AD-FABP4), and then detected its influence on mRNA expression of four differentiation-related genes (PPAR gamma, CEBPA, CEBPB, and SREBF1) and three lipid metabolism-related genes (ADIPOQ, LEP and LEPR) of adipocytes. The FABP4 mRNA content, derived from bovine adipocytes, decreased by 41% (P < 0.01) after 24 h and 66% (P < 0.01) after 72 h of AD-FABP4 infection. However, lower mRNA content of FABP4 did not significantly alter levels of differentiation-related gene expression at 24 h following AD-FABP4 treatment of bovine-derived preadipocytes (P = 0.54, 0.78, 0.89, and 0.94, respectively). Meanwhile, knocking down (partially silencing) FABP4 significantly decreased ADIPOQ (P < 0.05) and LEP (P < 0.01) gene expression after 24 h of AD-FABP4 treatment, decreased ADIPOQ (P < 0.01) and LEP (P < 0.01) gene expression, but increased LEPR mRNA expression (P < 0.01) after a 72-h treatment of bovine preadipocytes. We conclude that FABP4 plays a role in fat deposition and metabolic syndrome by regulating lipid metabolism-related genes (such as ADIPOQ, LEP and LEPR), without affecting the ability of preadipocytes to differentiate into adipocytes.

To compare the calibration results obtained at different resolutions, the near infrared (NIR) spectra of samples were obtained using an FT-NIR spectrometer at resolutions of 4 cm(-1), 8 cm(-1) and 16 cm(-1). Fat contents of samples were determined using a gas chromatography method. Generally, higher resolution provides better predictions for all types of fats. Each type of fat had its own optimum resolution: 4 cm(-1) for trans and 8 cm(-1) for cis fat models. At optimal resolution, the models predicted trans and cis fat contents with a SEP and r(2) of 0.75% and 0.96, and 0.70% and 0.96, respectively. The results indicated that the trans and cis fat content of cereal products could be determined in minutes without the need for oil extraction within the accuracy required for sample screening (RPD=4.3 or 4.81.

The full-length of the C4H ortholog was cloned using degenerate primers and the RACE (rapid amplification of cDNA ends) method. The full-length C4H ortholog contained a 1,518-bp open reading frame (ORF) encoding 505 amino acids. The deduced amino acid sequence showed that kenaf C4H had the highest similarity (95%) with that of Gossypium arboretum. We examined the expression patterns of the C4H ortholog in diverse tissues and at different developmental stages, as well as in response to abiotic stress conditions such as wounding, NaCl, cold, H2O2, ABA (abscisic acid) and SA (salicylic acid). Three-week-old stem tissues were used to examine the effects of abiotic stresses on C4H ortholog expression. While the highest transcript level of C4H ortholog was observed at an early stage in both stems and leaves, the transcripts were most abundant in the late stage flowers. In cases of wounding and SA, early induction of the C4H ortholog was observed. Conversely, H2O2 led to intermediate induction, while cold and ABA led to late induction. NaCl treatment showed different expression patterns such as complex biphasic expression.

Based on loop-mediated isothermal amplification (LAMP), we developed a method for detecting Lxx. The major advantages of the LAMP method are visual judgment by color and time saving with only 60 min for identification of Lxx and without the need for costly PCR apparatus and gel scanner. In the present study, positive and negative samples detected by the LAMP method were clearly distinguishable. When total DNA extracted from internode juice was used as the template, the sensitivity of LAMP was 10 times higher than that of the conventional PCR detection. The LAMP assay is a highly specific, rapid, and sensitive method for the diagnosis of ratoon stunt caused by Lxx in sugarcane. This is the first report of LAMP-based assay for the detection of Lxx in sugarcane.

Validity of eight-electrode multifrequency BIA to estimate body composition in a healthy adult population SO EUROPEAN JOURNAL OF CLINICAL NUTRITION LA English DT Article DE body composition analysis; bioelectrical impedance; body shape; ethnicity; reference methods; four-compartment model ID BIOELECTRICAL-IMPEDANCE ANALYSIS; FAT-FREE MASS; WHOLE-BODY; PREDICTION; DILUTION; OBESITY; WATER; MODEL AB BACKGROUND/OBJECTIVES: The validity of bioelectrical impedance analysis (BIA) for body composition analysis is limited by assumptions relating to body shape. Improvement in BIA technology could overcome these limitations and reduce the population specificity of the BIA algorithm. SUBJECTS/METHODS: BIA equations for the prediction of fat-free mass (FFM), total body water (TBW) and extracellular water (ECW) were generated from data obtained on 124 Caucasians (body mass index 18.5-35 kg/m(2)) using a four-compartment model and dilution techniques as references. The algorithms were validated in an independent multiethnic population (n = 130). The validity of BIA results was compared (i) between ethnic groups and (ii) with results from the four-compartment model and two-compartment methods (air-displacement plethysmography, dual-energy X-ray absorptiometry and deuterium dilution). RESULTS: Indices were developed from segmental R and Xc values to represent the relative contribution of trunk and limbs to total body conductivity. The coefficient of determination for all prediction equations was high (R-2: 0.94 for ECW, 0.98 for FFM and 0.98 for TBW) and root mean square error was low (1.9 kg for FFM, 0.8 l for ECW and 1.3 kg for TBW). The bias between BIA results and different reference methods was not statistically different between Afro-American, Hispanic, Asian or Caucasian populations and showed a similar difference (- 0.2-0.2 kg FFM) when compared with the bias between different two-compartment reference methods (- 0.2-0.3 kg FFM). CONCLUSIONS: An eight-electrode, segmental multifrequency BIA is a valid tool to estimate body composition in healthy euvolemic adults compared with the validity and precision of other two-compartment reference methods. Population specificity is of minor importance when compared with discrepancies between different reference methods. C1 [Bosy-Westphal, A.; Schautz, B.; Later, W.; Mueller, M.

TI Exotic annual grass invasion alters fuel amounts, continuity and moisture content SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE cheatgrass; fire risk; invasive plants; wildfire ID BROMUS-TECTORUM L; SAGEBRUSH-STEPPE; ALIEN PLANTS; NORTH-AMERICA; FIRE REGIMES; COMMUNITIES; AUSTRALIA; WOODLAND; DYNAMICS; DISTURBANCE AB Many exotic annual grasses are believed to increase wildfire frequency to the detriment of native vegetation by increasing fine fuels and thus, creating a grass-fire cycle. However, information on differences in fuel characteristics between invaded and non-invaded plant communities is lacking, or is based mainly on speculation and anecdotal evidence. We compared fuel biomass, cover, continuity and moisture content in plant communities invaded and not invaded by cheatgrass (Bromus tectorum L.), an exotic annual grass, in 2010 and 2011 in south-eastern Oregon, USA. Annual grass-invaded communities had higher fine fuel amounts, greater fuel continuity, smaller fuel gaps and lower fuel moisture content than did non-invaded plant communities. These conditions would increase the probability that ignition sources would contact combustible fuels and that fires would propagate. Fuel characteristics in the annual grass-invaded communities in our study may also support faster spreading fires. Fuel moisture content was low enough to burn readily more than a month earlier in annual grass-invaded communities than in non-invaded communities, thereby expanding the wildfire season. The cumulative effect of these differences in fuel characteristics between exotic annual grass-invaded and non-invaded plant communities is an increased potential for frequent, large-scale, fast-spreading wildfires. We suggest that research is needed to develop methods to mediate and reverse these changes in fuel characteristics associated with B. tectorum invasion.

An analysis of 15 communities in the United States that have increased their preparedness for wildfire allowed us to explore how education programs encouraged individual and community change. Agency-sponsored adult educational programs helped communities change their philosophy about firefighting, pass ordinances that restrict individual property rights, and empower residents to reduce their wildfire risk. This article explores several outcomes of these programs and offers suggested indicators of change that might be useful for education program evaluation.

Burial rates for sediment OC varied from 183 to 279 g OC m(-2) a(-1) over the lifetime of these reservoirs (about 50 years). Organic carbon averaged 39.4 mg per gram dry sediment (n = 137) and mean values varied from 20.3 to 54.8 mg OC per gram dry sediment among the reservoirs; these concentrations are within the mid-range of values reported from other lakes and reservoirs. Spatial distribution of OC generally showed an increase from the inflow to the dam and in some cases lateral gradients that varied by a factor of 2. Based on simple random sampling, 10 core samples provide relative precision of around 25% and equate to a mean of 0.8 samples per hectare. This analysis of sampling effort will be useful for global up-scaling of carbon sequestration in small impoundments.

Plants were subjected to seven aluminum (Al) concentrations and Al effects on growth, photosynthesis, and mineral content were assessed. Inter-genotypic differences for F-o,F- F-m and F-v fluorescences, as well as for F-v/F-m, were observed with increasing Al concentrations. There was a decreasing of F-o, F-m, F-v and F-v/F-m for the Catongo. Increasing Al concentration decreased photosynthetic rate, stomatal conductance and leaf transpiration rate, however, inter-genotypic differences in these parameters were not observed. The Al-treatments decreased content of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) in different plant parts, with the exception of K content in stems of Theobahia and in leaves of both genotypes. Theobahia showed higher tolerance to Al phytotoxicity, manifested mainly in the higher levels of Al in the growth medium. Inter-genotypic differences were observed in the growth and mineral nutrition.

A convergence of these issues is occurring in the Midwestern United States, i.e. the 'cornbelt' region that provides substantial grain supplies to world markets but is also well known for its contribution to hypoxic conditions in the Gulf of Mexico due to agricultural nutrient losses. This review examines anticipated trends in climate and possible consequences for grain production and soil resource management in this region. The historic climate of this region has been ideal for large-scale agriculture, and its soils are among the world's most productive. Yet under current trends, degradation of the soil resource threatens our capacity to ensure a stable food supply and a clean environment in the face of a changing climate. A set of strategies and practices can be implemented to meet these challenges by maintaining and improving hydrologic and plant-growth functions of soil, which will improve outcomes for aquatic ecosystems and for the agricultural sector. Soil management ensures our long-term capacity to provide a reliable food supply, and mitigates pressures to expand agricultural practices into marginal croplands that would lead to further environmental degradation.

We applied competitive ELISA (cELISA) and nested PCR diagnostic methods to detect this parasite in horses by screening 162 samples from mainland Portugal where the parasite is endemic, and 143 from the Azores representing both native and imported horse populations. We found that 2.8% of the Azorean samples tested positive exclusively by cELISA, 1.4% tested positive only by nested PCR, and 9.1% tested positive using both tests. Samples from the native Terceira Pony population were negative for both tests. The parasite was more prevalent in samples from mainland Portugal when both test methods were considered (9.3% positive exclusively by cELISA, 1.9% positive exclusively by nested PCR, and 16.7% positive for both tests). To our knowledge, this is the first time that molecular techniques have been used to detect T. equi in the Azores and the first report of this parasite in the archipelago. Based on this study, it is clear that the import of horses into the Azores and the movement of horses between the islands must be controlled to reduce the risk of new infections, contributing to the protection of native horse populations such as the Terceira Pony population.

TI Assessing net carbon sequestration on urban and community forests of northern New England, USA SO URBAN FORESTRY & URBAN GREENING LA English DT Article DE Forest carbon sequestration; Housing density; Percentage canopy cover; Net forest growth rate; Social and ecological studies ID LAND-COVER DATABASE; UNITED-STATES; CANOPY AB Urban and community forests play an important role in the overall carbon budget of the USA. Accurately quantifying carbon sequestration by these forests can provide insight for strategic planning to mitigate greenhouse gas effects on climate change. This study provides a new methodology to estimate net forest carbon sequestration (FCS) in urban and community lands of northern New England using ground based forest growth rates, housing density data, satellite derived land cover and tree canopy cover maps at the county level. We estimated that the region's urban and community forests sequestered 603,200 tC/yr ($38.7 million/yr value), contributing 8.2% of regional net forest ecosystem carbon sequestration. The contributions at the state level varied from 2.3% in Vermont to 16.6% in New Hampshire with substantial variation at the county level up to 73.3%. Spatially, contribution rates from urban and community forests at the county level were much higher and concentrated in southeast portion of NH and southwest portion of ME along the coast, and decreased toward inland areas. Our estimated net FCS compared reasonably with gross FCS in the region reported by a previous study. On average, the net FCS was 34.2% lower (varying from 41.9% lower in Vermont to 28.1% lower in Maine) than the corresponding gross FCS mainly because of a lower regional average net growth rate used in this study, compared to the national average gross carbon sequestration rate used in the previous study.

Heim, Alexander Zheng, Chengyang Shortle, Walter TI Climate warming shifts carbon allocation from stemwood to roots in calcium-depleted spruce forests SO GLOBAL BIOGEOCHEMICAL CYCLES LA English DT Article ID NORTHEASTERN UNITED-STATES; TREE-GROWTH; NORWAY SPRUCE; BUD BURST; SOIL; TEMPERATURE; ACCUMULATION; DEPOSITION; LATITUDES; RESPONSES AB Increased greening of northern forests, measured by the Normalized Difference Vegetation Index (NDVI), has been presented as evidence that a warmer climate has increased both net primary productivity (NPP) and the carbon sink in boreal forests. However, higher production and greener canopies may accompany changes in carbon allocation that favor foliage or fine roots over less decomposable woody biomass. Furthermore, tree core data throughout mid- and northern latitudes have revealed a divergence problem (DP), a weakening in tree ring responses to warming over the past half century that is receiving increasing attention, but remains poorly understood. Often, the same sites exhibit trend inconsistency phenomenon (TIP), namely positive, or no trends in growing season NDVI where negative trends in tree ring indexes are observed. Here we studied growth of two Norway spruce (Picea abies) stands in western Russia that exhibited both the DP and TIP but were subject to soil acidification and calcium depletion of differing timing and severity. Our results link the decline in radial growth starting in 1980 to a shift in carbon allocation from wood to roots driven by a combination of two factors: (a) soil acidification that depleted calcium and impaired root function and (b) earlier onset of the growing season that further taxed the root system. The latter change in phenology appears to act as a trigger at both sites to push trees into nutrient limitation as the demand for Ca increased with the longer growing season, thereby causing the shift in carbon allocation.

The concept of biotic homogenization through the invasion of a certain serious invasive plant species merit more studies. Hence, we used field surveys to quantitatively compare invasive populations of Solidago canadensis (SC) in China with the control sites (adjacent sites to SC present sites yet without the species) and SC native populations in the USA. We found that plant communities in SC invaded habitats shared similarities with those in SC native ranges. Bray-Curtis similarity clearly showed that the composition of plant communities in SC invaded habitats were similar to those in SC native ranges. Both in the native and introduced range, plant communities with SC present were characterized by SC being dominant, significantly lower species richness, alpha-diversity and beta-diversity, as well as a decrease in the correlation coefficient between geographic distance and floristic similarities. SC favors fertile and moist loam habitat, while it dominated in various habitats in China, where more than 20 different dominants should have occurred. In conclusion, serious invasive species can quickly remodel and homogenize diverse communities by dominating them.

A reasonable linear relationship was found between product yield and pK(a) of the axial ligand. The current work, using density functional calculations, examined geometric, electronic, and energetic parameters to determine if additional quantitative relationships can be identified and used in subsequent catalyst design. Good relationships with yield were identified with the geometry of the salen ligand and the charge on the ligand nitrogen coordinated to the cobalt.

Historically, much of these data have been collected by observers in aircraft documenting visible damage using a technique known as aerial detection survey (ADS) or sketchmapping. ADS is an efficient method but produces coarse scale data. We used one meter natural color imagery to conduct a photo interpretation survey (PIS) to compare the resulting data with the annual ADS data. The study area consists of a portion of the Black Hills National Forest that is currently experiencing mountain pine beetle-induced conifer mortality. Ground plots were used to compare how accurately each survey method delineated forest damage and results indicate a statistically significant difference (alpha 0.05) between ADS and PIS and a trend toward no significant difference when a buffer is considered. Substantial differences in the average size of polygons, total number of polygons, and total area mapped were observed. Our results indicate that current estimates of mortality intensity in our study area are low and remedies should be investigated. Photo surveys over the Black Hills National Forest are less efficient but yield damage polygons with higher accuracy and with fewer errors of commission than traditional ADS.

The objective of this study was to compare the availability of phosphorus (P) from broiler litter ash (BLA), egg layer manure ash (ELMA) and calcium phosphate for corn, wheat and soybean. Other elements such as arsenic are also concentrated in the ashed litter. Calcium phosphate, BLA and ELMA were mixed with soil at 40 and 80mg P kg(1). Crops were grown for about six weeks. Biomass and phosphorus concentrations were highest for plants grown on the calcium phosphate treatments. At the highest phosphorus rate, phosphorus concentrations were 1135,963 and 939mg kg(1) in corn shoot for calcium phosphate, ELMA and BLA, respectively. Arsenic concentrations for plants grown on ash treatment were similar to the control. Results from this study indicated that phosphorus in the ash was not readily available for crop uptake.

We present substantial extension to the existing theory and practice of using temperature time series to estimate streambed water fluxes and thermal properties, including (1) a new explicit analytical solution to predict one-dimensional fluid velocity from amplitude and phase information; (2) an inverse function, also with explicit formulation; (3) methods to estimate fluid velocity from temperature measurements with unknown depths; (4) methods to estimate thermal diffusivity from the temperature time series when measurement depths are known; (5) methods to track streambed elevation between two sensors, given knowledge of the thermal diffusivity from (4) above; (6) methods to directly calculate the potential error in velocity estimates based on the measurement error characteristics; and (7) methods for validation of parameter estimates. We also provide discussion and theoretical insights developed from the solutions to better understand the physics and scaling of the propagation of the diurnal temperature variation through the streambed. In particular, we note that the equations developed do not replace existing equations applied to the analysis, rather they are new equations representing new aspects of the process, and, as a consequence, they increase the amount of information that can be derived from a particular set of thermal measurements.

Widespread tree mortality, currently affecting pinon-juniper ecosystems in southwestern North America, may affect C substrate availability in several ways, for example, via litterfall pulses and loss of root exudation. To determine pinon mortality effects on C and water limitation of microbial respiration, we applied field amendments (sucrose and water) to two pinon-juniper sites in central New Mexico, USA: one with a recent (<1 yr), experimentally induced mortality event and a nearby site with live canopy. We monitored the respiration response to water and sucrose applications to the litter surface and to the underlying mineral soil surface, testing the following hypotheses: (1) soil respiration in a pinon-juniper woodland is water-and labile C-limited in both the litter layer and mineral soil; (2) pinon mortality reduces the C limitation of litter respiration; and (3) pinon mortality enhances the C limitation of mineral soil respiration. Litter respiration at both sites responded to increased water availability, yet surprisingly, mineral soil respiration was not limited by water. Consistent with hypothesis 2, C limitation of litter respiration was lower at the recent mortality site compared to the intact canopy site. Applications to the mineral soil showed evidence of reduction in CO2 flux on the girdled site and a non-significant increase on the control. We speculate that the reduction may have been driven by water-induced carbonate dissolution, which serves as a sink for CO2 and would reduce the net flux. Widespread pinon mortality may decrease labile C limitation of litter respiration, at least during the first growing season following mortality.

Such desiccation tolerance is known from vegetative cells of some species of algae and of major groups close to the evolutionary path of the angiosperms. It is also found in the reproductive structures of some algae, moss spores and probably the aerial spores of other terrestrial cryptogamic taxa. The occurrence of desiccation tolerance in the seed plants is overwhelmingly in the aerial reproductive structures; the pollen and seed embryos. Spatially and temporally, pollen and embryos are close ontogenetic derivatives of the angiosperm microspores and megaspores respectively. This suggests that the desiccation tolerance of pollen and embryos derives from the desiccation tolerance of the spores of antecedent taxa and that the basic pollen/embryo mechanism of desiccation tolerance has eventually become expressed also in the vegetative tissue of certain angiosperm species whose drought avoidance is inadequate in microhabitats that suffer extremely xeric episodes. The protective compounds and processes that contribute to desiccation tolerance in angiosperms are found in the modern groups related to the evolutionary path leading to the angiosperms and are also present in the algae and in the cyanobacteria. The mechanism of desiccation tolerance in the angiosperms thus appears to have its origins in algal ancestors and possibly in the endosymbiotic cyanobacteria-related progenitor of chloroplasts and the bacteria-related progenitor of mitochondria. The mechanism may involve the regulation and timing of the accumulation of protective compounds and of other contributing substances and processes.

TI Construction, expression, purification and antigenicity of recombinant Campylobacter jejuni flagellar proteins SO MICROBIOLOGICAL RESEARCH LA English DT Article DE Campylobacter jejuni; Flagella; epsilon-Proteobacteria; Food-borne pathogen; Zoonoses ID GUILLAIN-BARRE-SYNDROME; GLYCOSYLATION; PERSPECTIVE; PATHOGEN; COLONIZATION; HELICOBACTER; INFECTIONS; VIRULENCE; RESPONSES; MOTILITY AB Campylobacter jejuni, a flagellated, spiral-rod Gram-negative bacterium, is the leading etiologic agent of human acute bacterial gastroenteritis worldwide. The source of this microorganism for human infection has been implicated as consumption and handling of poultry meat where this microorganism is a commensal in the gut. Because the genomes of many C jejuni isolates have been sequenced, our ultimate goal is to develop protein arrays for exploring this microorganism and host interactions. In this communication, we report cloning, expression and purification of C jejuni flagellar proteins in a bacterial expression system. Twelve recombinant proteins were purified, which were confirmed by SDS-PAGE analysis and a His tag detection kit. The FlgE1, FlgG, FlgK, FliE, FlgH/FliH and FlaA recombinant proteins were further confirmed by LC-ESI-MS/MS. The purified recombinant proteins were tested whether they were immunogenic using antibodies from several sources. BacTrace anti-Campylobacter species antibody reacted to the FlaA recombinant protein, but not others. Rabbit anti-MOMP1 peptide antibody reacted strongly to FliE and weakly to FlaA, but not others. Rabbit anti-MOMP2 peptide antibody reacted strongly to the FlaA, FliG, FliE, FlhF, FlgG, FlgEl and FliD recombinant proteins, less to FlgK and FlgH/FliH, and did not react to the FliY, FliS and FliH recombinant proteins. These antibody studies suggest that these recombinant flagellar proteins have potential for novel targets for vaccine development. It is also anticipated that these recombinant proteins provide us a very useful tool for investigating host immune response to C jejuni. Published by Elsevier GmbH.

In this study, the thermodynamics of dimer formation from various oxidation products of a-pinene ozonolysis are investigated using a combination of Monte Carlo configuration sampling, semi-empirical and density functional theory (DFT) quantum mechanics, and continuum solvent modeling. Favorable dimer formation pathways are found to exist in both gas and condensed phases. The free energies of dimer formation are used to calculate equilibrium constants and expected dimer concentrations under a variety of conditions. In the gas phase, favorable pathways studied include formation of non-covalent dimers of terpenylic acid and/or cis-pinic acid and a covalently-bound peroxyhemiacetal. Under atmospherically relevant conditions, only terpenylic acid forms a dimer in sufficient quantities to contribute to new particle formation. Under conditions typically used in laboratory experiments, several dimer formation pathways may contribute to particle formation. In the condensed phase, non-covalent dimers of terpenylic acid and/or cis-pinic acid and covalently-bound dimers representing a peroxyhemiacetal and a hydrated aldol are favorably formed. Dimer formation is both solution and temperature dependent. A water-like solution appears to promote dimer formation over methanol-or acetonitrile-like solutions. Heating from 298 K to 373 K causes extensive decomposition back to monomers. Dimers that are not favorably formed in either the gas or condensed phase include hemi-acetal, ester, anhydride, and the di(alpha-hydroxy) ether.

Subsequently, it has emerged as a serious pathogen of cucurbitaceous plant species worldwide. In the major cucurbit producing countries of the world, great emphasis has been placed on managing this potentially devastating disease. Thus far, the most effective strategy for BFB management has been exclusion, which relies heavily on rapid and reliable pathogen detection. This review summarises recent progress in the development of A. citrulli detection techniques and evaluates their effectiveness as it pertains to BFB management. C1 [Feng, J. J.; Zhang, G.

Methyl 9(10)-oxooctadecanoate and methyl 9,10-dioxooctadecanoate were made by a ring-opening reaction of epoxidized methyl oleate using bismuth(III) trifluoromethanesulfonate (bismuth triflate) catalyst. Lower reaction temperatures favor the ketone, whereas higher temperatures are required to produce the diketone. The second synthesis also requires the use of dimethylsulfoxide to serve as an oxygen atom donor and that reagent also is needed to keep the catalyst in its active form. The ketone was also evaluated as a lubricity additive in soybean oil, where it was found that it had a minimal effect in reducing wear and did not improve oxidative stability. This drawback, while not good in lubricant formulations, is desirable in many applications such as paint and linoleum production. Also, the structure of the ketone could make it a desirable dielectric fluid, where the water sequestering ability of the carbonyl group would be desirable. Overall, this is an effective synthesis of promising materials, with high biobased content, useful for industries of the future.

Most new techniques in silage microbiology use the polymerase chain reaction (PCR) to make copies of a portion of the DNA in microorganisms. These techniques allow us to identify and quantify species as well as do community analysis. The PCR-based techniques are uncovering new species, both bacteria and fungi, during storage and feeding. Silage inoculants are widely available, but of greater interest has been research investigating why inoculants are so successful. Various inoculant strains have been found to produce bacteriocins and other compounds that inhibit other bacteria and fungi, improving their chances for success. In vitro ruminal fermentation research is showing that some inoculated silages affect rumen microorganisms, reducing methane in some cases and increasing microbial biomass production in others. Better understanding of silage microbiology will allow us to better manage silos and develop better inoculants to improve silage quality.

Water and 80% ethanol extracts of the silages were also analysed for effects on in vitro rumen fermentation. The inoculant affected lucerne silage characteristics but had little effect on the maize silages. In vitro fermentation of the silages showed few effects except increased microbial biomass yield (MBY) at 24 h in the inoculant-treated lucerne silages. In vitro fermentation of the lucerne silage water extracts produced no differences due to treatment except for reduced MBY in the inoculant-treated extracts. The ethanol extracts produced results inconsistent with the in vitro results of the silages. Consequently it appears that the factor in in vitro fermentation of inoculated silages causing increased MBY was in neither the water nor ethanol extracts.

We used data from 5,500 US beekeepers (5,244 backyard, 189 sideline and 67 commercial beekeepers) who responded to the April 2012 Bee Informed Partnership Winter Colony Loss Survey and calculated loss as the difference in the number of colonies between October 1, 2011 and April 1, 2012, adjusting for increases and decreases over that period. In the US, the total colony loss was 22.5% for the 2011-12 winter; 45.1% (n = 2,482) of respondents reported no colony loss. Total loss during 2011-12 was substantially lower than loss during 2010-11 (29.9%). Of the 4,484 respondents who kept bees in 2010-11 and 2011-12, 72.0% reported that the loss during 2011-12 was smaller or similar to the loss during 2010-11. There was substantial variation in total loss by state (range 6.2% to 47.7%). The average loss per beekeeping operation was 25.4%, but the average loss was not significantly different by operation type (backyard, sideline, commercial). The average self-reported acceptable loss per respondent was 13.7%; 46.8% (n = 2,259) of respondents experienced winter colony losses in excess of the average acceptable loss. Of beekeepers who reported losing at least one colony during 2011-12, the leading self-identified causes of mortality were weak condition in the fall and queen failure. Respondents who indicated poor wintering conditions, CCD, or pesticides as a leading cause of mortality suffered a higher average loss when compared to beekeepers who did not list these as potential causes.

RTB was introduced into China in the early 1980s and spread rapidly from Shanxi Province to four adjacent provinces; it has infested over 500,000 ha of pine forest and has caused extensive tree mortality since 1999. We provide a historical background on RTB outbreaks, explanations for its invasive success, management options, and economic impacts of RTB in China. Genetic variation in RTB fungal associates, interactions between RTB and its associated fungi, behavioral differences in Chinese RTB, and other factors favoring RTB outbreaks are considered in an effort to explain the invasiveness of RTB in China. The promise of semiochemicals as a management tool is also discussed.

TI Combining resource selection and movement behavior to predict corridors for Canada lynx at their southern range periphery SO BIOLOGICAL CONSERVATION LA English DT Article DE Canada lynx; Connectivity; Corridors; Least-cost paths; Montana; Resource selection ID NORTHERN ROCKY-MOUNTAINS; YELLOWSTONE-NATIONAL-PARK; HABITAT FRAGMENTATION; CLIMATE-CHANGE; CONSERVATION CORRIDORS; LANDSCAPE; CONNECTIVITY; MODELS; AVAILABILITY; POPULATIONS AB Maintaining connectivity with source populations is especially important for populations of boreal species at the southern edge of their distributions, where anthropogenic disturbance and climate change can be a threat. In the conterminous United States, Canada lynx Lynx canadensis is a federally threatened boreal species that may require connectivity with northern populations to persist. Connectivity is a function of movement between patches and the likelihood that patches are suitable for resident populations. Therefore, we combined resource selection, step selection, and least-cost path models to define empirically movement corridors for lynx in the Northern Rocky Mountains. We used telemetry data for 64 lynx monitored during 1998-.2007 to create a broad-scale resource selection model that predicted probable lynx habitat across the species' distribution in the Northern Rocky Mountains. Our model indicated that lynx selected home ranges at mid-elevations with low surface roughness and high canopy cover. Based on a subset of 37 (16 females, 21 males) adult lynx fitted with GPS collars from 2005 to 2007, we then tested the extent to which remotely-sensed indices of environmental heterogeneity, including greenness, normalized difference vegetation index, surface roughness, and a principal component that indexed stand age, could characterize landscape connectivity for lynx. We found that connectivity between lynx habitat in Canada and that in the conterminous US is facilitated by only a few putative corridors that extend south from the international border. Maintaining the integrity of these connectivity corridors is of primary importance to lynx conservation in the Northern Rockies. Published by Elsevier Ltd.

This study presents analyses of ceilometer measurements of smoke plume heights for twenty prescribed burns in the south-eastern United States. Measurements were conducted from mid-winter to early summer between 2009 and 2011. Approximately half of the burns were on tracts of land over 400 ha (1000 acres) in area. Average smoke plume height was similar to 1 km. Plume height trended upward from winter to summer. These results could be used as an empirical guideline for fire managers to estimate smoke plume height in the south-eastern US when modelling and measurement are not available. The average could be used as a first-order approximation, and a second-order approximation could be obtained by using the average for spring and autumn seasons, and decreasing or increasing by 0.2 km the average for winter or summer. The concentrations of particulate matter with an aerodynamic diameter less than 2.5 or 10 mu m (PM2.5 and PM10) within smoke plumes calculated from ceilometer backscatter are similar to 80 and 90 mu g m(-3), and trend downward from winter to summer. Large smoke concentrations are found in the lower portion of smoke plumes for many burns. Smoke plume height shows fast and uniform fluctuations at minute scales for almost all burns and slow and irregular fluctuations at scales from tens of minutes to hours for some burns.

TI Field validation of a free-agent cellular automata model of fire spread with fire-atmosphere coupling SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article ID ANOMALOUS DIFFUSION; SIMULATING FIRE; GRASS FIRES; BEHAVIOR; DYNAMICS; WIND AB A cellular automata fire model represents 'elements' of fire by autonomous agents. A few simple algebraic expressions substituted for complex physical and meteorological processes and solved iteratively yield simulations for 'super-diffusive' fire spread and coupled surface-layer (2-m) fire-atmosphere processes. Pressure anomalies, which are integrals of the thermal properties of the overlying heated plume, drive the surface winds around and through the fire. Five simulations with differing fuel and wind conditions were compared with fire and meteorological data from an experimental grassfire (FireFlux). The fire model accurately simulated bulk patterns of measured time-series of 2-m winds at two towers and observed fire behaviour (spread rate, flaming depth and heat released). Fidelity to spatial windfields in the vicinity of the fire was similar to results from full-physics fire models for other grassfires. Accurate predictions of fire spread depend critically on accurate wind speeds and directions at the location of the fire. Simulated fire-atmosphere coupling using FireFlux data increased wind speeds across the fire line by up to a factor of three. With its computational speed relative to full-physics models, the fire model can inform full-physics modellers regarding problems of interest. Although the fire model is tested for homogeneous fuels on flat terrain, the model is designed for simulating complex distributions of fire within heterogeneous distributions of fuels over complex landscapes.

TI Measurements of convective and radiative heating in wildland fires SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article ID MEDITERRANEAN SHRUB; SPREAD; FUEL AB Time-resolved irradiance and convective heating and cooling of fast-response thermopile sensors were measured in 13 natural and prescribed wildland fires under a variety of fuel and ambient conditions. It was shown that a sensor exposed to the fire environment was subject to rapid fluctuations of convective transfer whereas irradiance measured by a windowed sensor was much less variable in time, increasing nearly monotonically with the approach of the flame front and largely declining with its passage. Irradiance beneath two crown fires peaked at 200 and 300 kW m(-2), peak irradiance associated with fires in surface fuels reached 100 kW m(-2) and the peak for three instances of burning in shrub fuels was 132 kW m(-2). The fire radiative energy accounted for 79% of the variance in fuel consumption. Convective heating at the sensor surface varied from 15% to values exceeding the radiative flux. Detailed measurements of convective and radiative heating rates in wildland fires are presented. Results indicate that the relative contribution of each to total energy release is dependent on fuel and environment.

Evaluation of the data in the time and frequency domain indicate that this sampling rate was sufficient to capture the temporal fluctuations of radiative and convective heating. The convective heating signal contained significantly larger fluctuations in magnitude and frequency than did the radiative heating signal. The data were artificially down-sampled to 100, 50, 10, 5 and 1 Hz to explore the effect of sampling rate on peak heat fluxes, time-averaged heating and integrated heating. Results show that for sampling rates less than 5 Hz the difference between measured and actual peak radiative heating rates can be as great as 24%, and is on the order of 80% for 1-Hz sampling rates. Convective heating showed degradation in the signal for sampling rates less than 100 Hz. Heating rates averaged over a 2-s moving window, as well as integrated radiative and convective heating were insensitive to sampling rate across all ranges explored. The data suggest that peak radiative and convective heating magnitudes cannot be fully temporally resolved for sampling frequencies lower than 20 and 200 Hz.

TI Wildfire ignition-distribution modelling: a comparative study in the Huron-Manistee National Forest, Michigan, USA SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE GLM; Maxent; Random Forests ID SPECIES DISTRIBUTION MODELS; SOUTHERN CALIFORNIA; SPATIAL-PATTERNS; FIRE OCCURRENCE; UNITED-STATES; CLASSIFICATION; PERFORMANCE; LANDSCAPE; PREDICTION; REGRESSION AB Wildfire ignition distribution models are powerful tools for predicting the probability of ignitions across broad areas, and identifying their drivers. Several approaches have been used for ignition-distribution modelling, yet the performance of different model types has not been compared. This is unfortunate, given that conceptually similar species-distribution models exhibit pronounced differences among model types. Therefore, our goal was to compare the predictive performance, variable importance and the spatial patterns of predicted ignition-probabilities of three ignition-distribution model types: one parametric, statistical model (Generalised Linear Models, GLM) and two machine-learning algorithms (Random Forests and Maximum Entropy, Maxent). We parameterised the models using 16 years of ignitions data and environmental data for the Huron-Manistee National Forest in Michigan, USA. Random Forests and Maxent had slightly better prediction accuracies than did GLM, but model fit was similar for all three. Variables related to human population and development were the best predictors of wildfire ignition locations in all models (although variable rankings differed slightly), along with elevation. However, despite similar model performance and variables, the map of ignition probabilities generated by Maxent was markedly different from those of the two other models. We thus suggest that when accurate predictions are desired, the outcomes of different model types should be compared, or alternatively combined, to produce ensemble predictions.

This paper investigates the tradeoffs fire managers are willing to make among these objectives using a choice experiment methodology that provides three key advancements relative to previous stated-preference studies directed at understanding fire manager preferences: (1) a more immediate relationship between the instrument employed in measuring preferences and current management practices and operational decision-support systems; (2) an explicit exploration of how sociopolitical expectations may influence decision-making and (3) consideration of fire managers' relative prioritisation of cost-containment objectives. Results indicate that in the current management environment, choices among potential suppression strategies are driven largely by consideration of risk to homes and high-value watersheds and potential fire duration, and are relatively insensitive to increases in cost and personnel exposure. Indeed, when asked to choose the strategy they would expect to choose under current social and political constraints, managers favoured higher-cost suppression strategies, ceteris paribus. However, managers indicated they would personally prefer to pursue strategies that were more cost-conscious and proportionate with values at risk. These results confirm earlier studies that highlight the challenges managerial incentives and sociopolitical pressures create in achieving cost-containment objectives.

In this manuscript, we focus on the economics of fire and aviation management within the US Forest Service. Substantial uncertainties challenge comprehensive analysis of airtanker use, prompting calls from federal oversight agencies for improved aerial firefighting data collection and analysis. Here, we explore the availability and sufficiency of agency aviation data to track airtanker use and cost trends, and to categorise airtanker use by mission type and fire size class. Although the primary intended use of the airtanker fleet is for initial attack of wildfires, our results indicate that the use of these aircraft tends to occur for extended attack or large-fire support, with a significant number of flights associated with very large fires greater than 4047 ha (10 000 acres). Our results highlight apparent trends in airtanker use that challenge our ability to evaluate cost-effectiveness of airtankers. Data quality and availability issues limited our analysis, leading to a recommendation for improved data collection on flight objective and drop location. We conclude by offering suggested avenues of future research that may help address informational and analytical shortcomings.

Preference heterogeneity among survey respondents was examined using three econometric models and risk preferences were evaluated by comparing willingness to pay for wildfire protection programs against expected monetary losses. The results showed that while nearly all respondents had risk seeking preferences, a small segment of respondents were risk neutral or risk averse. Only respondents who had personal experience with the effects of wildfire consistently made trade-offs among risk, loss and cost and these respondents were willing to pay more for wildfire protection programs than were respondents without prior experience of the effects of wildfire. The degree to which people with prior experience with the effects of wildfire can effectively articulate an economic rationale for investing in wildfire protection to other members of their own or other communities facing the threat of wildfires may influence the overall success of wildfire protection programs.

TI Econometric analysis of fire suppression production functions for large wildland fires SO INTERNATIONAL JOURNAL OF WILDLAND FIRE LA English DT Article DE efficiency; fireline productivity; fractal dimension; random parameters; returns to scale; selective rationality ID WILDFIRE; MODEL; CONTAINMENT; MANAGEMENT; SIMULATION; DIMENSION AB In this paper, we use operational data collected for large wildland fires to estimate the parameters of economic production functions that relate the rate of fireline construction with the level of fire suppression inputs (handcrews, dozers, engines and helicopters). These parameter estimates are then used to evaluate whether the productivity of fire suppression inputs during extensive fire suppression efforts are similar to productivity estimates derived from direct observation and used as standard rates by the US Forest Service. The results indicated that the production rates estimated with operational data ranged from similar to 14 to 93% of the standard rates. Further, the econometric models indicated that the productivity of all inputs taken together increases more than proportionally as their use is increased. This result may indicate economies of scale in fire suppression or, alternatively, that fire managers learn how resources may be deployed more productively over the course of a fire. We suspect that the identified productivity gaps are primarily due to unobserved factors related to fire behaviour, other resources at risk, firefighter fatigue, safety considerations and managerial decision-making. The collection of more precise operational data could help reduce uncertainty regarding the relative importance of factors that contribute to productivity shortfalls.

The taxonomic revision is here supported using molecular genetic and hybridization studies. Four Diorhabda species separated into five dades using cytochrome c oxidase subunit 1 sequence data with Diorhabda elongata separating into two clades. Amplified fragment length polymorphism (AFLP) analysis using genomic DNA revealed only four dades, which corresponded to the four morphospecies. Hybridization between the four species yielded viable eggs in F-1 crosses but viability was significantly lower than achieved with intraspecific crosses. Crosses involving Diorhabda carinulata and the other three species resulted in low F-2 egg viability, whereas crosses between D. elongata, Diorhabda sublineata and Diorhabda carinata resulted in > 40% F-2 egg viability. Crosses between D. carinulata and the other three species resulted in high mortality of D. carinulata females due to genital mismatch. AFLP patterns combined with principal coordinates analysis enabled effective separation between D. elongata and D. sublineata, providing a method to measure genetic introgression in the field.

The interface between chemical ecology and biological control of weeds presents a rich opportunity to exploit potentially coevolved relationships between agents and plants where chemical factors mediating interactions are important. Five topics seem relevant, which if implemented could improve the predictability of host range determination, agent establishment, and impact on the target weed. (1) The host secondary plant chemistry and a potential biological control agent's response to that chemistry can be exploited to improve predictability of potential agent host range. (2) Evolutionary changes may occur in secondary plant chemistry of invasive weeds that have been introduced to novel environments and exposed to a new set of biotic and abiotic stressors. Further, such a scenario facilitates rapid evolutionary changes in phenotypic traits, which in turn may help explain one mechanism of invasiveness and affect the outcome of biological control and other management options. (3) Herbivores can induce production of secondary plant compounds. (4) Variability of weed secondary chemistry which, either constitutive or inducible, can be an important factor that potentially. influences the performance of some biological control agents and their impact on the target weed. (5) Finally, sequestration of secondary plant chemistry may protect herbivores against generalist predators, which might improve establishment of a biological control agent introduced to a new range and eventually impact on the target weed. Recognition of these patterns and processes can help identify the factors that impart success to a biological control program.

This suggests growth regulators might be used to control invasive annual grasses by depleting their short-lived seed banks. The goal of this study was to extend the previous Japanese brome research to downy brome (Bromus tectorum L.), the most damaging invasive annual grass of U.S. grasslands. In a greenhouse, we found picloram did not greatly influence downy brome seed production, while point estimates suggest aminopyralid reduced seed production 55 to 80%. If not for a highly abnormal retillering response that we somewhat doubt would occur in the field, point estimates suggest aminopyralid would have reduced downy brome seed production approximately 90% when applied at the heading stage and approximately 98% when applied at three earlier growth stages. Our greenhouse study should encourage field studies designed to further explore the potential for using growth regulators to control downy brome and other invasive annual grasses.

SO INVASIVE PLANT SCIENCE AND MANAGEMENT LA English DT Article DE Cheatgrass; Great Basin; seed bank; seed pathogen; stand failure ID PATHOGEN AB Downy brome (cheatgrass) is a highly successful, exotic, winter annual invader in semi-arid western North America, forming near-monocultures across many landscapes. A frequent but poorly understood phenomenon in these heavily invaded areas is periodic 'die-off' or complete stand failure. The fungal pathogen Pyrenophora semeniperda is abundant in cheatgrass seed banks and causes high mortality. To determine whether this pathogen could be responsible for stand failure, we quantified late spring seed banks in die-off areas and adjacent cheatgrass stands at nine sites. Seed bank analysis showed that this pathogen was not a die-off causal agent at those sites. We determined that seed bank sampling and litter data could be used to estimate time since die-off. Seed bank patterns in our recent die-offs indicated that the die-off causal agent does not significantly impact seeds in the persistent seed bank.

The DC3000 PSPTO4723 (cmaL) gene is located in a genomic region encoding type III effectors; however, it promotes chlorosis in the model plant Nicotiana benthamiana in a manner independent of type III secretion. Coronatine is produced by the ligation of two moieties, coronafacic acid (CFA) and coronamic acid (CMA), which are produced by biosynthetic pathways encoded in separate operons. Cross-feeding experiments, performed in N. benthamiana with cfa, cma, and cmaL mutants, implicate CmaL in CMA production. Furthermore, analysis of bacterial supernatants under coronatine-inducing conditions revealed that mutants lacking either the cma operon or cmaL accumulate CFA rather than coronatine, supporting a role for CmaL in the regulation or biosynthesis of CMA. CmaL does not appear to regulate CMA production, since the expression of proteins with known roles in CMA production is unaltered in cmaL mutants. Rather, CmaL is needed for the first step in CMA synthesis, as evidenced by the fact that wild-type levels of coronatine production are restored to a Delta cmaL mutant when it is supplemented with 50 mu g/ml L-allo-isoleucine, the starting unit for CMA production. cmaL is found in all other sequenced P. syringae strains with coronatine biosynthesis genes. This characterization of CmaL identifies a critical missing factor in coronatine production and provides a foundation for further investigation of a member of the widespread DUF1330 protein family.

BVDV are major pathogens of cattle, and infection results in significant economic loss worldwide. A new putative pestivirus species, tentatively called "HoBi-like," "BVDV-3," or "atypical pestiviruses," was first identified in Europe in fetal bovine serum (FBS) imported from Brazil. HoBi-like viruses are related to BVDV at the genetic and antigenic levels. Further, the disease caused by these new viruses resembles clinical presentations historically associated with BVDV infection, including growth retardation, reduced milk production, respiratory disease, reduced reproductive performance, and increased mortality among young stock. Current BVDV diagnostic tests may fail to detect HoBi-like viruses or to differentiate between BVDV and HoBi-like viruses. Further, commercial tests for BVDV exposure, based on serological response, do not reliably detect HoBi-like virus exposure, and cross protection against HoBi-like viruses conferred by current BVDV vaccines is likely limited. As many HoBi-like viruses, characterized to date, were isolated from FBS originating from Brazil, it is assumed that the agent is probably widespread in Brazilian herds. Nevertheless, reports of natural infection in Southeast Asia and Europe demonstrate that these viruses are not restricted to South America. Increased demand for FBS has led to widespread distribution of FBS originating in HoBi-like virus endemic regions. The contamination of such FBS with HoBi-like viruses may lead to spread of this virus to other regions.

However, direct fecal polymerase chain reaction (PCR) is becoming more widely used, demonstrating similar sensitivity and specificity to culture. To ensure efficient and reproducible PCR results from a difficult sample matrix such as feces, there are many obstacles that a DNA extraction method must overcome, including the presence of inhibitors and the thick waxy cell wall of MAP. In the current study, 6 commercial DNA extraction kits were evaluated using fecal samples from naturally infected cattle shedding various amounts of MAP. Upon extraction, DNA purity and yield were measured, and real-time PCR was performed for detection of the insertion sequence (IS) 900 and ISMAP02 targets. The kits evaluated showed significant differences in the purity and yield of DNA obtained. The best results were observed with kits E and A, having identified 94% (16/17) and 76% (13/17) of the positive samples by IS900 PCR, respectively. Both of these kits utilized bead beating in a lysis solution for cell disruption, followed by spin column technology (kit E) or magnetic bead-based technology (kit A) for nucleic acid isolation and purification. Two kits (A and F) demonstrated improved performance when used in conjunction with the respective manufacturer's PCR test. The present study demonstrates the importance of choosing the correct methodology for the most accurate diagnosis of paratuberculosis through fecal PCR.

Pupae from Chinese crabapple were smaller than those from sweet cherry, Prunus avium (Linnaeus) Linnaeus (Rosaceae), but fecundity and longevity of flies from the two hosts did not differ. Laboratory experiments were conducted to compare larval development in crabapples and cherries. 'Snowdrift' crabapples (Malus 'Snowdrift') did not produce pupae. Percentages of 'Indian Magic'(Malus 'Indian Magic') + 'Radiant' crabapple (Malus 'Radiant') vs. sweet cherry replicates that produced pupae did not differ in two no-choice experiments (36.7 vs. 41.7% and 13.3 vs. 33.5%, respectively). In a choice experiment, the percentage of crabapple replicates that produced pupae (6.7%) was lower than that of cherry replicates (42.2%). Egg to pupal development times in crabapples (18.0-21.2 d) were longer than in cherries (15.4-16.7 d) and pupae from the crabapples were smaller. Results suggest crabapples are not optimal developmental hosts for R. indifferens but that Chinese and 'Indian Magic' + 'Radiant' crabapples can occasionally allow late-season flies to bridge the gap between one generation and the next when no cherries are available.

TI Factors Influencing Changes in U.S. Hardwood Log and Lumber Exports from 1990 to 2011 SO BIORESOURCES LA English DT Article DE Hardwood lumber; Hardwood logs; Exports; Exchange rates; International trade AB Domestic consumption of hardwood products in the United States since 2000 has trended downward, making exports the single most important market for higher grade hardwood lumber and a major market for higher value hardwood logs. Between 1990 and 2011, hardwood lumber exports increased by 46%. During most of this period, Canada was the largest export market for U. S. lumber, but in 2009 China/Hong Kong became the most important market. Nearly 60% of the lumber exported in 1990 was red or white oak, but the proportion of exports of these species had decreased to 38% by 2011. By contrast, exports of yellow-poplar lumber increased by 381% over this period. The volume of hardwood logs exported grew by 62% between 1990 and 2011, and Canada remained the largest customer. Several factors can affect the export of hardwood lumber and logs. In the 1990s, changes in exchange rates and economic activity in importing countries could be linked with changes in lumber and log exports. Since 2000, China, Vietnam, and other East Asian furniture-producing countries have become important export markets as overseas manufacturers seek lumber of species familiar to U.S. consumers. Conversely, the large decrease in hardwood lumber and log exports to Canada between 2006 and 2009 coincides with a similar decrease in wood furniture imports from Canada.

To aid managers and researchers address this disease, an updated and accessible review of cave hibernacula and cave microclimates is presented. To maximize energy savings and reduce evaporative water loss during winter, most temperate vespertilionid bats in North America select caves with temperatures between 2 and 10 degrees C, with 60%-100% relative humidity. Generally, the temperature in caves is similar to the mean annual surface temperature (MAST) of a region, which varies by latitude, altitude, and topography. However, MAST for most areas where caves are found in eastern North America is well above 10 degrees C. Thus, various factors cause cold-air infiltration that reduces temperatures of these caves during winter. These factors include depth of cave, topographic setting, airflow patterns, cave configuration, and water infiltration. Factors affecting humidity, condensation, and evaporation are also addressed. In areas where MAST is above or below the thermal requirements of Geomyces destructans, many caves used by bats as hibernacula may still provide favorable sites for optimal growth of this fungus.

In the treated pine (TP), the mass was reduced by approximately 20%, and the extract was composed mainly of degradation products of hemicelluloses. Wood flour produced from TP and unextracted chips (untreated pine, UP) was blended with high-density polyethylene (HDPE) and polypropylene (PP) and was extruded into wood plastic composites (WPCs). Formulations for WPCs consisted of 58% pine, 32% plastic, and 10% other additives. WPC based on HDPE+TP and PP+TP absorbed 46-45% less water than did WPC based on HDPE+UP and PP+UP, respectively. Thickness swelling was reduced by 45-59%, respectively, after 2520 h of immersion. The diffusion constant decreased by approximately 36%. Evaluation of mechanical properties in flexure and tension mode indicated improvements in TP-WPC properties, although the data were not statistically significant in all cases. Results showed that debarking of ponderosa pine is not required for WPC production. C1 [Raul Pelaez-Samaniego, Manuel] Washington State Univ, Dept Biol Syst Engn, Pullman, WA 99164 USA.

TI Cost analysis of commercial pasteurization of orange juice by pulsed electric fields SO INNOVATIVE FOOD SCIENCE & EMERGING TECHNOLOGIES LA English DT Article DE Pulsed electric fields; Cost analysis; Orange juice; Energy ID FOOD AB The cost of pulsed electric field (PEF) pasteurization of orange juice was estimated. The cost analysis was based on processing conditions that met the US FDA (5 log reduction) requirement for fruit juice pasteurization and that achieved a sufficient microbial shelf-life. PEF-treated samples processed at 30 kV/cm and 60 degrees C had reductions in Escherichia coli, Salmonella Typhimurium and Lactobacillus spp. of greater than 5 log and had a microbial shelf-life of 2 months at 4 degrees C. Total pasteurization cost was estimated to be 3.7 cent/L. Of this, capital costs accounted for 54% (2.0 cent/L), labor costs accounted for 35% (1.3 cent/L) and utility charges, mainly electricity, accounted for 11% (0.4 cent/L). The total PEF cost was 147% (2.2 cent/L) more than that of conventional thermal processing (1.5 cent/L). A deeper knowledge of the processing costs of PEF technology will afford companies a better understanding of the benefits and limitations of nonthermal processing. Industrial relevance: Pasteurization of orange juice by pulsed electric fields (PEF) results in a higher quality product compared to traditional thermal pasteurization. However, industry has not embraced this new technology and the main reason for this may be the lack of a comprehensive cost analysis. A large-scale commercial PEF system was designed and the total pasteurization cost was estimated to be 3.7 cent/L. The total PEF cost was 2.2 cent/L more than that of traditional thermal processing. A thorough knowledge of the processing costs will provide companies with a better understanding of the pros and cons of PEF pasteurization. Published by Elsevier Ltd.

Wherever appropriate cell culture models are lacking, scientific development is hampered. Unfortunately this has been and still is the case in honey bee research, because permanent honey bee cell lines have not so far been established. To overcome this hurdle, protocols for the cultivation of primary honey bee cells and of non-permanent honey bee cell lines have been developed. In addition, heterologous cell culture models for honey bee pathogens based on non-Apis insect cell lines have recently been developed. To further advance this progress and to encourage bee scientists to enter the field of cell biology based research, here we present protocols for the cultivation of honey bee primary cells and non-permanent cell lines, as well as hints for the cultivation of permanent insect cell lines suitable for honey bee research.

The reason is their social lifestyle, which sets them apart from a "typical insect" and, during social evolution, has resulted in the restructuring of certain physiological pathways and biochemical characteristics in this insect. Not surprisingly, the questions that have attracted most attention by researchers working on honey bee physiology and biochemistry in general are core topics specifically related to social organization, such as caste development, reproductive division of labour and polyethism within the worker caste. With certain proteins playing key roles in these processes, such as the major royal jelly proteins (MRJPs), including royalactin and hexamerins in caste development, and vitellogenin in reproductive division of labour and age polyethism, a major section herein will present and discuss basic laboratory protocols for protein analyses established and standardized to address such questions in bees. A second major topic concerns endocrine mechanisms underlying processes of queen and worker development, as well as reproduction and polyethism, especially the roles of juvenile hormone and ecdysteroids. Sensitive techniques for the quantification of juvenile hormone levels circulating in haemolymph, as well as its synthesis by the corpora allata are described. Although these require certain instrumentation and a considerable degree of sophistication in the analysis procedures, we considered that presenting these techniques would be of interest to laboratories planning to specialize in such analyses. Since biogenic amines are both neurotransmitters and regulators of endocrine glands, we also present a standard method for the detection and analysis of certain biogenic amines of interest. Further questions that cross borders between individual and social physiology are related to energy metabolism and thermoregulation. Thus a further three sections are dedicated to protocols on carbohydrate quantification in body fluid, body temperature measurement and respirometry.

Chalkbrood, caused by Ascosphaera apis, is a common and widespread disease that can result in severe reduction of emerging worker bees and thus overall colony productivity. Stonebrood is caused by Aspergillus spp. that are rarely observed, so the impact on colony health is not very well understood. A major concern with the presence of Aspergillus in honey bees is the production of airborne conidia, which can lead to allergic bronchopulmonary aspergillosis, pulmonary aspergilloma, or even invasive aspergillosis in lung tissues upon inhalation by humans. In the current chapter we describe the honey bee disease symptoms of these fungal pathogens. In addition, we provide research methodologies and protocols for isolating and culturing, in vivo and in vitro assays that are commonly used to study these host pathogen interactions. We give guidelines on the preferred methods used in current research and the application of molecular techniques. We have added photographs, drawings and illustrations to assist bee-extension personnel and bee scientists in the control of these two diseases.

In parallel studies, cold-treated plants were shown to have relatively increased amounts of ninhydrin positive material during 5-24 h recovery period from cold stress. Here we report on changes in free amino acid levels in sour orange leaves in the 24 h recovery period following the termination of the chilling treatment. Proline was most abundant amino acid and increased in response to chilling treatment; it remained at higher level than initially during the first 5 h recovery period and then declined to initial level after 24 h. In addition, amino acids, such as serine, glutamic acid, glycine, lysine, isoleucine, tyrosine, arginine and histidine, increased due to cold treatment and/or during recovery after cold treatment, while asparagine, phenylalanine, leucine, alanine and threonine either decreased or remained unchanged in response to cold stress and during immediate recovery period. The special pattern with which levels of different free amino acids change in response to cold stress might have important implications on interactions between Asian citrus psyllids and citrus host plants.

A second functional thermostable nuclease (here termed as Nuc2) in S. aureus was characterized after recombinant expression in Escherichia coll. Sequence alignment and phylogenetic analysis revealed that Nuc2 was a more conserved protein in the staphylococci group compared with Nucl. Recombinant Nuc2 showed nuclease activity in the zymogram test and was able to degrade various types of nucleic acids. The optimal reaction temperature and pH for Nuc2 were 50 C and pH 10, respectively. The enzymatic activity of Nuc2 was stimulated in the presence of Ca2+ (0.05 mM), Mg2+ (0.5 mM), dithiothreitol, beta-mecaptoethanol, TritonX-100, Tween-20, and urea; however, activity decreased sharply when exposed to heavy metals such as Zn2+ and Mn2+, and in the presence of EDTA or SDS. Nuc2 showed weaker activity, lower thermostability and different sensitivity to these chemical agents compared with Nucl, which was consistent with differences in the sequence pattern and structure predicted. Furthermore, a nuc1 and nuc2 double deletion mutant of S. aureus and respective complementation experiments suggest a major role for nuc1 in terms of thermonuclease activity in S. aureus.

TI Tissue-Specific Copper Concentrations in Red Drum after Long-Term Exposure to Sublethal Levels of Waterborne Copper and a 21-Day Withdrawal SO NORTH AMERICAN JOURNAL OF AQUACULTURE LA English DT Article ID CHANNEL CATFISH; SULFATE; TROUT; ZINC; BIOACCUMULATION; MORTALITY; PUNCTATUS; TOXICITY; MUSCLE; GROWTH AB Juvenile Red Drum Sciaenops ocellatus were exposed to sublethal concentrations of waterborne copper (Cu; 0.250.35mg/L) for 242 d using an ethanolamine chelated Cu compound as a prophylactic treatment to control ectoparasites in recirculating aquaculture systems. Skin, muscle, gill, liver, and intestine tissues were collected on days 1, 3, 5, 15, and 21 during the 21-d depuration. Liver and intestine tissues accumulated Cu at a rate that was strongly influenced by the environmental Cu load. Skin, gills, and muscle tissues did not accumulate substantial amounts of Cu despite its presence at therapeutic levels. The rank order of the Cu concentrations in the different tissues was as follows: intestine > liver > gills > skin > muscle. Predictive equations for tissue Cu concentrations (g/g) relative to time of withdrawal (d) and waterborne Cu concentration (mg/L) were generated using trend analysis. The relationships between tissue Cu concentrations and time of withdrawal were significant, with all tissue Cu concentrations decreasing over time. The relationships between tissue Cu concentrations and waterborne Cu concentration were also significant, with elevated waterborne Cu concentrations resulting in higher tissue Cu concentrations, especially in the intestine, liver, and gill tissue samples. Red Drum cultured in recirculating aquaculture systems had lower (2652-g/g) detectable Cu concentrations in muscle tissue than wild-caught Red Drum (414g/g).

TI Influences of Cyclic, High Temperatures on Juvenile Channel Catfish Growth and Feeding SO NORTH AMERICAN JOURNAL OF AQUACULTURE LA English DT Article ID ICTALURUS-PUNCTATUS; CONVERSION RATIO; BODY-COMPOSITION; FOOD CONVERSION; FISH GROWTH; CONSUMPTION; EFFICIENCY; RESPONSES; RATES; TOLERANCE AB Effects of high summer temperatures on Channel Catfish Ictalurus punctatus are poorly understood, particularly for thermal regimes that mimic pond aquaculture conditions. Therefore, this study examined the effects of three cycling upper-range temperature regimes (2327 degrees C, 2731 degrees C, and 3135 degrees C) characteristic of aquaculture environments in the Mississippi Delta. Feed conversion ratio, feed consumption, specific growth rate, activity levels, survival, and overall growth in terms of wet weight and TL were measured in fingerling channel catfish over an 8-week period in a flow-through, multiple-tank system. Specific growth rate, feed consumption, TL, and wet weight of fish increased significantly in the 2731 degrees C treatment in contrast to the 2327 degrees C and 3135 degrees C treatments. Feed conversion ratio was lowest in the 2731 degrees C treatment, whereas activity levels were highest in the 3135 degrees C treatment. Survival significantly decreased for catfish in the warmest treatment compared with catfish in the coolest treatment. These results indicate that high temperatures decrease growth in Channel Catfish, largely due to reduced food consumption and feed conversion and increased levels of activity. Therefore, increases in temperatures, such as from climate change, present challenges to the culture and management of Channel Catfish.

TI Evaluation of Hydrolyzed Poultry Feathers as a Dietary Ingredient for Pond-Raised Channel Catfish SO NORTH AMERICAN JOURNAL OF AQUACULTURE LA English DT Article ID ANIMAL PROTEIN INGREDIENTS; ICTALURUS-PUNCTATUS; FISH-MEAL; GROWTH; FEEDS; CARP; L. AB The present study examined the use of hydrolyzed poultry feathers (HPF) as a replacement for soybean meal in diets for pond raised Channel Catfish Ictalurus punctatus. Four isonitrogenous (28% crude protein) diets were evaluated that contained 0, 5, 10, or 15% HPF. Fingerling Channel Catfish (mean +/- SD initial weight was 47.5 +/- 2.2 g) were stocked into twenty 0.04-ha earthen ponds at a rate of 14,830 fish/ha. Fish were fed once daily to apparent satiation for 140 d. No significant differences were observed for weight gain, feed conversion ratio (FCR), and survival among fish fed various levels of HPF. There were also no significant differences in net yield of fish fed diets containing 0, 5, and 10% HPF, but net yield of fish fed a diet containing 15% HPF was significantly lower than that of fish fed the control diet. Fish on diets containing 5% HPF and above were fed significantly less feed than fish fed the control diet. Regression analysis showed that total amount of diet fed, net yield, and weight gain decreased linearly as dietary HPF levels increased. Based on weight gain and net yield data, 5% HPF with supplemental lysine may be used in Channel Catfish diets without marked impact on fish growth performance. However, carcass and fillet yield were significantly reduced in fish fed diets containing 5% HPF and higher. Fillet protein generally decreased and fillet fat increased with increasing dietary HPF levels.

TI Growth and Acute Temperature Tolerance of June Sucker Juveniles Fed Varying Dietary Protein and Lipid Levels With and Without Supplemental Dicalcium Phosphate SO NORTH AMERICAN JOURNAL OF AQUACULTURE LA English DT Article ID FISH; METABOLISM; SALMON AB Reports from hatcheries have demonstrated that commercially available diets are inadequate for June Suckers Chasmistes liorus and suggest that fish quality can be improved through species-specific diet optimization. To determine dietary protein and lipid levels for juvenile June Suckers, practical-type diets were formulated with 35, 40, or 45% protein and 8, 12, or 16% lipid and tested in a 3x3 factorial design. Two additional diets (45% protein and 16% lipid [45:16] without dicalcium phosphate supplementation and 45:16 with 2x dicalcium phosphate) were formulated to test the necessity of dicalcium phosphate supplementation. Each diet was fed to three replicate tanks (average initial fish weight +/- SD = 4.48 +/- 0.24g) of fish per treatment (85 fish/tank); only duplicate tanks were used for the nondicalcium phosphate-supplemented treatment. Fish were reared in 80-L tanks supplied with 4 L/min of 22 degrees C spring water and fed 64% body weight (BW)/d by automated belt feeders, 6 d/week. At the end of 12weeks of culture, tissue samples were obtained to determine nutrient partitioning. An acute temperature challenge was also conducted to investigate dietary adequacy. Significant effects of diet on growth and temperature tolerance were observed. Fish fed the diet with 45% crude protein gained more weight than did fish fed 40% or 35% crude protein, and fish fed 16% dietary lipid gained more weight than did fish fed 12% and 8% crude lipid. However, the composition of this growth indicated that fish fed the 16% lipid stored larger amounts of lipid in both the visceral cavity and the muscle. A significant negative interactive effect of dietary protein and lipid on temperature tolerance was observed at 45% crude protein and 16% lipid. Results of this study define acceptable ranges of dietary protein and lipid for juvenile June Suckers and provide culturists information to make better choices regarding appropriate diets for this species.

In a laboratory study, small erosion pans and a programmable rain simulator were used to determine interrill erodibility, whereas in the field, rills were physically allocated in the field as plots of 0.1 by 10m within a ridge-furrow arrangement and five water-inflow rates were applied sequentially to determine rill erodibility and critical hydraulic shear. During the rain or inflows, runoff samples were taken and flow was characterised. The soils tested were Grey Vertosol, Black Vertosol, and Red Ferrosol. The fall velocity parameter, V-50, for rill soil and eroded sediment followed the order Red Ferrosol > Grey Vertosol > Black Vertosol, which Black Vertosol was the same order as observed for V-50 and mean weight diameter MWD) of aggregates in the interrill erosion experiment and D-50 of interrill eroded sediment, demonstrating differences between soils in dispersion and aggregate stability. The estimated values obtained by the WEPP model were not comparable to laboratory interrill erodibility values or to field rill erodibility values. Thus, erodibility parameters for physically based erosion models such a WEPP should be determined in the field for tropical soils, and new equations need to be developed to estimate such values based on soil properties for tropical soils.

Gregarious by nature, pigs kept in isolation may show behavioural and physiological signs of stress. In this study we investigated the preference of individually housed pigs, for social and non-social enrichments. Three enrichment items were compared: a mat (MAT), a companion (COM) and a mirror (MIR). Fourteen weaner pigs (Yorkshire x Landrace) were housed individually with continuous access to 4 adjacent pens. One pen was a control (CTRL) and had no enrichment; the others had one enrichment each, either a mat on part of the woven wire floor (MAT), a companion visible across the passageway (COM) or a mirror on one wall (MIR). Pigs spent more proportion of time (P=0.021) in the COM pen (0.65 +/- 0.07) compared to the CTRL pen (0.31 +/- 0.07) with the MAT pen (0.57 +/- 0.07) and the MIR (0.42 +/- 0.07) pen as intermediates. They also spent more total time engaged in investigative and inactive behaviours in the COM pen compared to the CTRL pen (P=0.007). A second analysis was performed to investigate changes in preferences in the presence or absence of a human in the room. The pens were then combined into two categories: social pens (COM and MIR) and nonsocial pens (MAT and CTRL). The probability of a pig being observed in the MIR pen when a human was present was significantly higher (P=0.0001), than when absent. Within the social enrichments, the probability of the animal being observed in either MIR or COM pen was not different (P=0.017). Our results confirm that preference studies may be highly sensitive to experimental conditions. Thus, the assumption that the most important preference is the one the animal spends most of its time with can be misleading. It appears that a mirror may be used by the animal for social support during periods of perceived threat, however further investigation is warranted. Published by Elsevier B.V.

TI Measurements of reactive trace gases and variable O-3 formation rates in some South Carolina biomass burning plumes SO ATMOSPHERIC CHEMISTRY AND PHYSICS LA English DT Article ID TRANSFORM INFRARED-SPECTROSCOPY; SECONDARY ORGANIC AEROSOL; FIRE EMISSIONS EXPERIMENT; UNITED-STATES; LABORATORY MEASUREMENTS; PARTICLE EMISSIONS; TROPICAL FOREST; ATMOSPHERIC CHEMISTRY; CARBONYL SULFIDE; PRESCRIBED FIRES AB In October-November 2011 we measured trace gas emission factors from seven prescribed fires in South Carolina (SC), US, using two Fourier transform infrared spectrometer (FTIR) systems and whole air sampling (WAS) into canisters followed by gas-chromatographic analysis. A total of 97 trace gas species were quantified from both airborne and ground-based sampling platforms, making this one of the most detailed field studies of fire emissions to date. The measurements include the first emission factors for a suite of monoterpenes produced by heating vegetative fuels during field fires. The first quantitative FTIR observations of limonene in smoke are reported along with an expanded suite of monoterpenes measured by WAS including alpha-pinene, beta-pinene, limonene, camphene, 4-carene, and myrcene. The known chemistry of the monoterpenes and their measured abundance of 0.4-27.9% of non-methane organic compounds (NMOCs) and similar to 21% of organic aerosol (mass basis) suggests that they impacted secondary formation of ozone (O-3), aerosols, and small organic trace gases such as methanol and formaldehyde in the sampled plumes in the first few hours after emission. The variability in the initial terpene emissions in the SC fire plumes was high and, in general, the speciation of the initially emitted gas-phase NMOCs was 13-195% different from that observed in a similar study in nominally similar pine forests in North Carolina similar to 20 months earlier. It is likely that differences in stand structure and environmental conditions contributed to the high variability observed within and between these studies. Similar factors may explain much of the variability in initial emissions in the literature. The Delta HCN/Delta CO emission ratio, however, was found to be fairly consistent with previous airborne fire measurements in other coniferous-dominated ecosystems, with the mean for these studies being 0.90+/-0.06 %, further confirming the value of HCN as a biomass burning tracer. The SC results also support an earlier finding that C3C4 alkynes may be of use as biomass burning indicators on the time-scale of hours to a day. It was possible to measure the downwind chemical evolution of the plume on four of the fires and significant O-3 formation (Delta O-3/Delta CO from 1090 %) occurred in all of these plumes within two hours. The slowest O-3 production was observed on a cloudy day with low co-emission of NOx. The fastest O-3 production was observed on a sunny day when the downwind plume almost certainly incorporated significant additional NOx by passing over the Columbia, SC metropolitan area. Due to rapid plume dilution, it was only possible to acquire high-quality downwind data for two other trace gas species (formaldehyde and methanol) during two of the fires. In all four of these cases, significant increases in formaldehyde and methanol were observed in < 2 h. This is likely the first direct observation of post-emission methanol production in biomass burning plumes. Post-emission production of methanol does not always happen in young biomass burning plumes, and its occurrence in this study could have involved terpene precursors to a significant extent.

Cost-intensive physical, chemical, biological pretreatment operations and slow enzymatic hydrolysis make the overall process of lignocellulosic conversion into biofuels less economical than available fossil fuels. Lignocellulose conversions carried out at <= 50 degrees C have several limitations. Therefore, this review focuses on the importance of thermophilic bacteria and thermostable enzymes to overcome the limitations of existing lignocellulosic biomass conversion processes. The influence of high temperatures on various existing lignocellulose conversion processes and those that are under development, including separate hydrolysis and fermentation, simultaneous saccharification and fermentation, and extremophilic consolidated bioprocess are also discussed.

Merr.] cultivars with elevated concentrations of the alpha' subunit of beta-conglycinin (BC) may provide health benefits to soy protein consumers. Two Monsanto single nucleotide polymorphism markers were used to classify F-2 plants in four segregating populations as having elevated alpha' concentration (EAP) or normal alpha' concentration (NAP). Seeds from one F-3 progeny of each F-2 plant were analyzed for protein composition by sodium dodecyl-sulfate polyacrylamide gel electrophoresis. Of the 800 plants in the four populations evaluated with the two markers, 82% were correctly classified for the EAP trait and 80% for the NAP trait. The EAP and NAP traits were evaluated in combination with the four glycinin genotypes gy1,2, Gy3, gy4, Gy5; gy1,2, Gy3, gy4, gy5; gy1,2, gy3, gy4, Gy5; and gy1,2, gy3, gy4, gy5. The seed yield, time of maturity, and protein and oil concentration were evaluated for 18 F-3:5 lines in each of the eight genotypic classes of the four populations at three environments in 2011. The EAP trait resulted in a significant increase in the alpha' and beta subunits of BC and a decrease in the alpha subunit, with no consistent impact on total BC, total glycinin, seed yield, maturity, and protein and oil concentrations. It should be possible to develop acceptable soybean cultivars that have the EAP trait in combination with the glycinin genotype gy1,2, gy3, gy4, gy5 to obtain a high concentration of the alpha' subunit and total BC with no glycinin for soy-based food products.

Our previous work with the intermated B73 x Mo17 maize (Zea mays L.) population revealed significant variation for grain yield and stover-quality traits important for cellulosic ethanol production. Our objectives were to determine (i) if realized gains from selection are larger with GWS than with marker-assisted recurrent selection (MARS), which involves selection for markers with significant effects; and (ii) how multiple traits respond to multiple cycles of GWS and MARS. In 2007, testcrosses of 223 recombinant inbreds developed from B73 x Mo17 (Cycle 0) were evaluated at four Minnesota locations and genotyped with 287 single nucleotide polymorphism markers. Individuals with the best performance for a Stover Index and a Yield + Stover Index were intermated to form Cycle 1. Both GWS and MARS were then conducted until Cycle 3. Multilocation trials in 2010 indicated that gains for the Stover Index and Yield + Stover Index were 14 to 50% larger (significant at P = 0.05) with GWS than with MARS. Gains in individual traits were mostly nonsignificant. Inbreeding coefficients ranged from 0.28 to 0.38 by Cycle 3 of GWS and MARS. For stover-quality traits, correlations between wet chemistry and near-infrared reflectance spectroscopy predictions decreased after selection. We believe this is the first published report of a GWS experiment in crops, and our results indicate that using all available markers for predicting genotypic value leads to greater gain than using a subset of markers with significant effects.

TI Resistance of Poncirus and Citrus x Poncirus Germplasm to the Asian Citrus Psyllid SO CROP SCIENCE LA English DT Article ID DIAPHORINA-CITRI; HEMIPTERA PSYLLIDAE; HOST-PLANT; FLORIDA; HOMOPTERA; KUWAYAMA; BIOLOGY; DISEASE AB The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, has spread to citrus growing regions nearly worldwide and transmits phloem-limited bacteria (Candidatus Liberibacter spp.) that are putatively responsible for citrus greening disease. Host plant resistance may provide the most effective control, but ACP has a broad host range and resistance in Citrus spp. and relatives to ACP has not been widely documented. Very low abundances of ACP were found on two accessions of Poncirus trifoliata (L.) Raf. (hardy-orange) in a field survey. Therefore, we tested whether 81 accessions of P. trifoliata and x Citroncirus spp. (hybrids of P. trifoliata and Citrus spp.) from the USDA-ARS National Clonal Germplasm Repository for Citrus and Dates were resistant to ACP by determining whether these accessions influence oviposition and lifespan of adults in no-choice tests. There was a higher abundance of eggs on the control (Citrus macrophylla Wester [alemow]) than nearly all accessions of P. trifoliata, and zero eggs were laid on 36% of the accessions. Additionally, more eggs were laid on the control than 10 of 34 accessions of xCitroncirus spp. Lifespan of adults was approximately 2.5 to 5 times longer on 11 of the 17 trifoliates and trifoliate hybrids we tested. Poncirus trifoliata appears to have antixenosis and antibiosis resistance to ACP, but we must next identify the traits that promote resistance to create commercial varieties of citrus that reduce the population of ACP and lower the incidence of citrus greening disease.

TI Genetic Analysis of Visually Scored Orange Kernel Color in Maize SO CROP SCIENCE LA English DT Article ID ASSOCIATION MAPPING POPULATION; VITAMIN-A-DEFICIENCY; GENOME-WIDE ASSOCIATION; PHYTOENE SYNTHASE; QUANTITATIVE RESISTANCE; NUTRITIONAL QUALITY; FUNCTIONAL-ANALYSIS; CAROTENOID CONTENT; ENDOSPERM COLOR; FLOWERING TIME AB Increasing levels of provitamin A carotenoids in maize (Zea mays L.) grain through plant breeding has potential to help humans suffering from vitamin A deficiency. In parts of Africa where this deficiency is prevalent, there is a consumer preference for white maize grain and an avoidance of yellow maize grain. White grain has minimal levels of carotenoids whereas yellow grain can have appreciable levels of carotenoids. There is a new effort to introduce orange maize that contains high levels of provitamin A, which appears to be a more acceptable color than yellow to consumers in Africa. The implementation of this program requires backcross selection to convert African-adapted germplasm with white grain to orange. We conducted a study to assess the heritability of visual scores for relative intensity of orange kernel color and identify genetic markers associated with orange color across and within 10 families of the maize nested association mapping population. We found visually scored kernel color to have a moderately high heritability and identified five common quantitative trait loci (QTL) and six rare QTL for intensity of orange color. Notably, half of them coincided with carotenoid biosynthetic genes. Our results indicate that breeders in Africa, Asia, and throughout the world would have flexibility to select for orange kernel color visually and/or with gene-specific markers. Such selection can be combined with marker-assisted selection efforts to increase provitamin A levels in maize grain.

TI Ionomic Characterization of Maize Kernels in the Intermated B73 x Mo17 Population SO CROP SCIENCE LA English DT Article ID QUANTITATIVE TRAIT LOCI; ARABIDOPSIS-THALIANA; MINERAL CONCENTRATIONS; MICRONUTRIENT CONTENT; NATURAL VARIATION; FLOWERING TIME; RICE GRAIN; LINES; QTL; IDENTIFICATION AB Dietary mineral deficiencies affect nearly half of the people on our planet, largely due to poverty. Enhancing nutritional quality-or biofortification-represents an efficient and sustainable potential solution to this massive public health problem. To create biofortified crops, one must understand the genetic and environmental factors that influence the ionome, or collection of mineral nutrients, in the target organism and tissue. We describe the use of quantitative trait loci (QTL) mapping to characterize the maize (Zea mays L.) grain ionome illustrated by the intermated B73 x Mo17 (IBM) recombinant inbred population. Ionomic profiling was applied to field grown materials from Florida, North Carolina, and New York. Twenty-seven QTL were detected for 10 traits derived from the North Carolina and New York grown maize explaining between 4 and 46% of the variance observed. For biofortification to succeed, QTL effective in multiple environments need to be the targets for improvement efforts. Florida grown maize were sampled shallowly to provide a low cost dataset to evaluate the models based on the combined North Carolina and New York traits. Twenty-five QTL were detected as significant in two or more locations using ANOVA on the original single location and/or site data; 12 QTL were found to be significant in Florida. While this strategy may have not detected every potential QTL from our data, we suggest these QTL effective in multiple environments represent a starting position for the biofortification of maize grain.

TI Soybean Aphid Injury Effects on Shoot Nitrogen Components in Glycine max SO CROP SCIENCE LA English DT Article ID NITRATE REDUCTASE; HIGHER-PLANTS; ROOT-NODULES; N-2 FIXATION; YIELD LOSS; UREIDE; METABOLISM; TRANSPORT; GREENHOUSE; ACCUMULATION AB Knowledge of soybean aphid (Aphis glycines Matsumura) effects on soybean [Glycine max (L.) Merr.] shoot N components may improve understanding of how plants are injured by this invasive pest. This 2-yr field study was conducted to measure soybean aphid effects (initial infestation of 0, 10, 50, or 100 aphids plant(-1) at the fifth node [V5] stage) on cumulative aphid-days as well as resulting soybean aphid populations plant(-1), shoot dry weight (DW), nitrate N, and ureide N measured at full bloom (R2), beginning pod (R4), full pod (R5), and beginning seed (R6). Cumulative aphid-days, which quantifies both the number of aphids present on plants and the duration of their feeding time, were similar across initial aphid infestation treatments. Compared with control plants, aphid feeding injury reduced shoot DW by about 40% and increased shoot nitrate N concentrations by about 45% across all initial infestation rates tested. Shoot nitrate N accumulation was increased about 20% by the 10 aphids plant(-1) treatment. In contrast, shoot ureide N concentrations in aphid-injured plants were similar to levels observed for uninjured plants. This lack of a concentration effect resulted in about a 36% decrease in ureide N accumulation in aphid-injured plants. These differential responses may result because nitrate N can be absorbed directly from the soil solution while ureide N biosynthesis has a higher energy requirement that cannot be met under severe aphid infestations.

Understanding the population structure present within Zoysia germplasm can assist plant breeders in exploiting available variation. The objectives of this study were to assess simple sequence repeat (SSR) allelic diversity within and among Zoysia spp., evaluate the genetic constitution of putative interspecific hybrids, and determine if Zoysia spp. and hybrids can be differentiated by inflorescence traits. Sixty-two Zoysia accessions selected as a subset of genotypically and phenotypically diverse genotypes were evaluated with 50 SSR markers and six inflorescence traits. Both an unweighted pair group method with arithmetic averaging (UPGMA) phylogram and principal coordinate analysis (PCO) analysis revealed a continuum of genetic variation present within and among the species. The model-based program STRUCTURE revealed two distinct subpopulations within Z. japonica Steud. as well as a distinct Z. matrella (L.) Merr. subpopulation. Based on SSR analysis, 23 Zoysia accessions evaluated had evidence of admixture. Six inflorescence phenotypes also revealed a continuous range of variation. This study was able to verify the presence of hybrids between Z. japonica and Z. matrella and provided further evidence for the hypothesis that Zoysia spp. are subpopulations or ecotypes within one species and not separate species.

TI Allele-specific amplification for the detection of ascochyta blight resistance in chickpea SO EUPHYTICA LA English DT Article DE Chickpea; Ascochyta blight; Allele-specific associated primers; Marker assisted selection ID CICER-ARIETINUM L.; MARKER-ASSISTED SELECTION; QUANTITATIVE TRAIT LOCI; IDENTIFICATION; INHERITANCE; CROSS; QTLS; MAP AB A new co-dominant molecular marker, CaETR, was developed based on allelic sequence length polymorphism in an ethylene receptor-like gene located in the genomic region of a QTL (QTL(AR1)) conferring ascochyta blight resistance in chickpea. This marker not only discriminated resistance and susceptible phenotypes of chickpea to ascochyta blight, but also easily detected heterozygous genotypes. Using the CaETR marker in combination with a previously developed co-dominant SCAR marker (SCY17(590)) linked to another QTL (QTL(AR2)) it was possible to detect resistance alleles in 90 % of resistant accessions in a collection of landraces, advances breeding lines and cultivars, and also detected susceptible alleles in all cases. The results of this study offer a scope for improving the efficiency of conventional chickpea breeding by carrying out negative selection for QTL(AR1) and QTL(AR2) in early generations without relaying directly on the phenotype. This PCR-based approach using both co-dominant markers is proposed as an efficient tool for selecting blight-resistant genotypes in breeding programs.

TI Evaluation and QTL mapping of phosphorus concentration in soybean seed SO EUPHYTICA LA English DT Article DE Phosphorus; Phytate; QTL; Seed ID QUANTITATIVE TRAIT LOCI; PHYTIC ACID; GLYCINE-MAX; PHOSPHATE-TRANSPORT; LOW-PHYTATE; IRON; ZINC; POPULATION; SEQUENCE; PROTEIN AB Phosphorus (P) is an essential macronutrient required for many biological and metabolic plant functions. Phosphate is the form of P used by plants. Reducing the amount of P in the seed can further aide breeding efforts to reduce the amount of P released into the environment due to the indigestibility of the complexes formed with metal ions. Analysis of the variation of phosphorus concentration in soybean seed under non-stressed conditions revealed that phosphorus ranged from 3,948.1 to 5,695.8 mu g/g total phosphorous (TP) in combined years. The averages for independent years were significantly different from one another. Quantitative trait loci (QTL) analysis of TP was performed to identify candidate gene(s) that is (are) involved in P accumulation in soybean seed. One putative QTL region was identified on chromosome 12 in the combined data that contained a phosphate transporter gene. Two additional suggestive QTL were identified on chromosomes 7 and 17 with chromosome 7 having both a phosphate transport gene and a ZIP transporter gene in the region of the QTL. There were additional genes in these regions that are involved in phosphate metabolism and transport. C1 [Lauter, Nick; Scott, M.

TI A new gene that controls seed coat wrinkling in soybean SO EUPHYTICA LA English DT Article DE Early Soybean Production System (ESPS); Germinability; High temperature; Seed coat wrinkling; Seed quality; Soybean; SSR ID TEMPERATURE; GERMINATION; GERMINABILITY; IRRIGATION; INHERITANCE; CHARACTER; VIGOR AB Seed coat wrinkling is a major factor affecting the germinability of soybean [Glycine max (L.) Merr.] seed produced in high-temperature environments, such as in the Early Soybean Production System of the midsouthern United States. Exposure of seed to high temperatures, coupled with alternating periods of wet and dry conditions, promotes seed coat wrinkling. This can predispose the seed to mechanical damage at harvest, further reducing germinability, and reducing the usability of the grain for seed beans. Previous studies identified a single recessive gene (shr) in a mutant line (T-311), located on chromosome 13 (linkage group F), which causes seed shriveling and seed coat wrinkling. The current study was undertaken to identify and genetically map new gene(s) that affect seed coat wrinkling. Crosses were made between a smooth-seeded accession (PI 567743) and a wrinkled-seeded accession (PI 87623). The parents, F-1, F-2, and BC1 generations were phenotyped for seed coat wrinkling in a greenhouse in Stoneville, MS during the summer of 2006. Genetic analysis indicated that the wrinkled seed coat trait in PI 87623 was inherited as a single recessive gene. A test for allelism, conducted in the greenhouse with a segregating F-2 population derived from T-311 x PI 87623, showed that the gene from PI 87623 is different from the shr gene in T-311. A field study of a larger population, derived from a reciprocal cross of the same parents, confirmed these results, but also suggested epistatic interactions between the genes. A linkage map was developed using 195 SSR and SNP markers on 168 F-2 individuals of the cross PI 567743 x PI 87623. Linkage analysis identified only one significant locus which was located on chromosome 5 (linkage group A1), confirming identification of a new gene that controls seed coat wrinkling in soybean. This study demonstrates genetic control of seed coat wrinkling, which offers the potential for selecting cultivars with less seed coat wrinkling for heat-stressed production environments.

The effect of particle size on enzymatic hydrolysis of pretreated Miscanthus x giganteus was determined. Miscanthus was ground using a hammer mill equipped with screens having 0.08,2.0 or 6.0 mm sieve openings. Particle size distribution and geometric mean diameters were determined for all samples. Ground samples were subjected to hot water, dilute acid or dilute ammonium hydroxide pretreatment. Enzyme hydrolysis was conducted on washed pretreated solids; sugar generation was used as a measure for pretreatment efficiency. Glucose and xylose concentrations were monitored using HPLC. Glucose and xylose profiles were generated and hydrolysis rates estimated. Glucose, xylose and total conversion yields were determined by comparing final sugar concentrations obtained to amounts present in pretreated biomass. Geometric mean diameters were the smallest from 0.08 mm sieve screen (56 mu m) followed by 2.0 mm (301 mu m) and 6.0 mm (695 mu m) screens. An increasing trend in percent total conversion was observed with decreasing mean particle size. Across all pretreatments, biomass ground using 0.08 mm screens resulted in highest total conversion. Enzyme hydrolysis of unpretreated biomass samples also resulted in increased total conversions as particle size decreased, although mean conversions (10-20%) were much lower than for pretreated biomass samples (53-94%), indicating the need for chemical pretreatments in biomass conversion.

New fermentation organisms hold tremendous potential for the production of biobased fuels, chemicals, and materials from industrial sugar feedstocks, in particular syrups. Clarification of sweet sorghum juice will be critical to the production of stable, intermediate syrup feedstocks for efficient transport, storage, and year-round supply. Juices extracted from mature sweet sorghum hybrids and immature cultivar Topper 76-6 (Topper), were clarified using heat, heat-milk of lime, and heat-milk of lime-polyanionic flocculant at various temperatures and target limed pHs, and compared to the clarification of sugarcane (Saccharum spp. hybrids) juice. There was no significant loss of fermentable sugars (sucrose + glucose + fructose) across clarification by temperature and only a slight decrease in fermentable sugars when clarified by pH. Preheating the sweet sorghum juice from 85 to 100 degrees C not only produced clarified juices of low turbidity, but also with excellent turbidity control. For the cultivars studied, a minimum limed juice pH of similar to 6.3-6.5 was optimum for the clarification of sweet sorghum juice preheated to similar to 80-85 degrees C with 5 ppm polyanionic flocculant addition with respect to clarified juice turbidity, protein, calcium, starch, and to a lesser extent phosphate levels. There was a strong effect of cultivar on juice quality, clarification performance, and clarified juice quality, which warrants further research. Published by Elsevier B.V.

Paulownia wood (PW) shavings were milled and separated into particle fractions and then blended with PLA with a single screw extruder. Mechanical and thermal properties were tested. Differential scanning calorimetry showed that PLA-PW blends containing smaller particle sizes had lower glass transition and melting temperatures compared to blends containing larger particle sizes. Biocomposites composed of smaller particles exhibited tensile strength values similar to neat PLA but had Young's modulus values that were 25% higher than neat PLA. However, elongation values decreased in all PLA-PW blends compared to neat PLA. Microscopic examination of the biocomposites revealed distinct differences in their morphologies. PLA-PWF blends exhibited color changes based on the size of the wood particles employed. Published by Elsevier B.V.

Plants were harvested 50 days after sowing and evaluated for nutrient uptake, the number of leaves, fresh and dry weight of shoot per plant and yield of major compounds in the essential oil. Accessions AMES 18596 and PI 171592 presented the following order of accumulation of macronutrients: K > N > Ca > Mg > P > S. For the accessions AMES 4998, PI 193770 and the cultivar Santo, the order K > N > Ca > P > Mg > S was observed. Micronutrients accumulation in cilantro shoot in descending order for all genotypes was: Fe > Zn > B > Mn > Cu. The highest number of leaves per plant was found in the accession AMES 18596 (9.94), while the others produced on average 7.24. Accessions AMES 18596 and PI 193770 produced 7.34g plant(-1) of fresh weight of shoots. Accession PI 171592 produced slightly higher yields (6.23 g plant(-1)) than the cultivar Santo and AMES 4998 (4.75 g plant(-1)). For dry weight of shoots, accessions AMES 18596 and PI 193770 produced the highest yields (0.58 g plant(-1)), followed by PI 171592 (0.47 g plant(-1)) and the accession AMES 4998 and the cultivar Santo that had on average 0.35 g plant(-1). The yield of the major compounds in the essential oil was higher for accessions AMES 18596 and PI 193770 (88.84 mu g plant(-1)) following by AMES 4998 and Santo (38.95 mu g plant(-1)) and PI 171592 (23.31 mu g plant(-1)). On average the yield of aliphatic aldehydes in fresh weight followed the order: trans-2-dodecenal > decanal > trans-2-decenal > tetradecenal > dodecanal > tetradecanal.

The new crop oils were compared as crude, refined, bleached, and deodorized - RBD, and purified (removal of fatty acids, FAs). Additionally, the physical properties of the new crop oils were compared to commercial vegetable oils, as well as to petroleum and synthetic motor oils. Pennycress and lesquerella had some of the best pour pints (PP, ASTM D 9796) among the new crop oils, -21 and -24 degrees C respectively, while castor from the commercial side had a PP of -30 degrees C. All the plant based oils, except castor and lesquerella, had excellent viscosity index (VI, ASTM D 2270-93) in the range of 167-231. New crop oils with an antioxidant additive (1-3%) were as oxidatively stable as current commercial petroleum products based on the rotating pressurized vessel oxidation test (RPVOT, ASTM D 2272-98) and gave times >200 min. Wear scar diameters (WSD, ASTM D 4172-94) of the vegetable-based oils from the 4-ball anti-wear test showed best results for cuphea and pennycress with WSD of 0.530 and 0.594 mm, respectively. In general, the new crop oils were found to have specific unique advantages over traditional commodity vegetable oils. Additionally, new crop oils compared favorably to both petroleum and synthetic commercial standards. Spider plots were used to compare the new crop oils on a defined visual and goodness scale.

Hydrothermal pretreatment and enzymatic saccharification were evaluated for conversion of corn stover cellulose and hemicellulose to fermentable sugars. Under the optimum conditions of hydrothermal pretreatment of corn stover (10%, w/v; 200 degrees C; 5 min) and enzymatic saccharification (45 degrees C, pH 5.0, 72 h), a total of 550 +/- 5 mg of fermentable sugars was obtained per g corn stover which is equivalent to 72% of theoretical sugar yield. The corn stover hydrolyzate was fermented without any detoxification by recombinant Escherichia coli strain FBR 5 at pH 6.5 and 37 degrees C for 74h to produce 20.9 +/- 0.5 g ethanol from 42.8 +/- 1.7 g sugars per L with a yield of 0.49 g ethanol per g available sugars and 0.27 g ethanol per g corn stover which is equivalent to 68.7% of theoretical ethanol yield from corn stover. This is the first report on the production of ethanol from hydrothermally pretreated corn stover by the recombinant bacterium. Published by Elsevier B.V.

TI Double-cropping with winter camelina in the northern Corn Belt to produce fuel and food SO INDUSTRIAL CROPS AND PRODUCTS LA English DT Article DE Camelina; Double-cropping; Biofuel; Oil yield; Food versus fuel ID PLANTING DATE; TILLAGE SYSTEMS; OIL COMPOSITION; SMALL GRAINS; COVER CROPS; SOWING DATE; SEED OIL; QUALITY; YIELD; WHEAT AB Camelina (Camelina sativa L) can be used as oilseed feedstock for biofuels. Recently, it was shown that fall-seeded winter camelina can be successfully grown in the upper Midwest USA and may be harvested early enough in the following summer to allow producing a second crop. Double-cropping may offer a profitable means of producing a dedicated biofuel crop without jeopardizing food security. To our knowledge no published information exists on exploring double-cropping with winter camelina. Therefore, a 2-yr field study was conducted between 2007 and 2009 in west central Minnesota to evaluate the agronomic and economic viability of producing short-season cultivars of soybean [Glycine max (L) Mem], oilseed sunflower (Helianthus annuus L), and forage millet (Setaria italica L.) after winter camelina in conventionally tilled and no-tilled soil. In most instances, yields of camelina and the second crop in the double-crop sequence differed between years but not by tillage practice. Averaged over both years, total oil yields for the camelina-soybean and camelina-sunflower sequences were 704 and 1508 L ha(-1). Compared to conventionally produced mono-crops, on average, double-crop soybean and sunflower yielded 82% and 72% of their mono-cropped counterparts, respectively. As expected, double-crop production costs were greater than for conventional mono-crops. However, in 2009 if camelina prices were similar to canola, net returns for double-crop camelina and soybean were $172-352 ha(-1) higher than for soybean alone, with highest double-crop net returns for conventional tillage. Furthermore, double-crop soybean seed protein content was little affected by late seeding, while double-crop sunflower oil content averaged over both years was about 13% lower than conventional sunflower sown at an optimum time. A winter camelina-food or -forage crop double-cropping system may be viable for the upper Midwest USA. Published by Elsevier B.V. C1 [Gesch, R.

TI Conformational change of metal phytates: Solid state 1D C-13 and 2D H-1-C-13 NMR spectroscopic investigations SO JOURNAL OF FOOD AGRICULTURE & ENVIRONMENT LA English DT Article DE Inositol phosphate; phytate; NMR; CPMAS; HETCOR; conformational change ID NUCLEAR-MAGNETIC-RESONANCE; PHYTIC ACID; INOSITOL PHOSPHATES; P-31 NMR; SOILS; IONS; PH AB Phytate is an important phosphorus and mineral storage compound in plant seeds. Both the benign and adverse effects of phytate in nutrition and environment are mainly due to its unique conformational structures, where a strong chelating ability makes phytate interact with many cations (such as Zn2+, Ca2+, Mg2+, and Al3+). However, information is scant on the conformational forms of different solid metal phytate compounds although phytate in solution exists in two conformations: one axial and five equatorial phosphates (1a/5e) structure and an inverted 5a/1e structure. Consequently, we investigated the spectral features of nine representative metal phytate compounds by solid state 1D C-13 cross polarization magic angle spinning (CPMAS) and 2D C-13-H-1 heteronuclear correlation (HETCOR) NMR. A broad peak appeared in all solid 1D NMR spectra of hydrogen monovalent, divalent, and trivalent metal phytate compounds. The spectra of hydrogen monovalent and divalent compounds could be deconvoluted to two separate resonance peaks. 2D HETCOR clearly showed distinct C-13-H-1 correlations for inositol C-H moieties in hydrogen metal phytates from non-hydrogen metal phytates. Through spectral comparison, this work demonstrated that different valent cations in solid phytate compounds could induce conformational changes of the inositol ring as pH does on the phytate in solution. Therefore, the current knowledge on the effect of pH on phytate conformation can be helpful in understanding the conformational changes of phytate when it interacts with different valent metals to form less soluble even insoluble compounds in the environment.

Results showed that a dramatic thickness increase exhibited in both CNF and CNF/PF films, despite being at different swelling levels. Compared to thickness swelling, however, the width expansion for these films is negligible. Such significant difference in dimensional swelling for CNF and PF modified films is mainly caused by nanofibril deposition and their mesostructure. However, addition of PF modifier has a positive effect on the constraint of water absorption and thickness swelling, which is strongly dependent on PF loadings.

The annotated SpliMNPV genome of 137,998 bp was found to harbor 132 open reading frames and 15 homologous repeat regions. Four unique genes not present in SpltMNPV were identified, as were 14 genes that were absent or translocated by comparison. Bioassay analysis of experimentally infected Spodoptera frugiperda revealed an extended killing time for SpliMNPV as compared to S. frugiperda MNPV (SfMNPV), but a level of mortality similar to that caused by infection with SfMNPV and superior to that of Autographa californica MNPV (AcMNPV). Although extensive similarity was observed between the genome structure and predicted translation products of SpliMNPV and Spodoptera litura MNPV (SpltMNPV), genetic distances between isolates of SpliMNPV and SpltMNPV suggest that they are in fact different species of genus Alpha baculovirus.

A total of 117 alleles were detected across eight SSR loci with the average of 14 alleles per locus. The genetic diversity of wild grapes was slightly lower than that observed in the cultivated grapes probably due to small populations and severe natural selection leading to drift and loss of alleles and heterozygosity in wild grapes. The distance cluster analysis (CA) supported the classical ecogeographic groups with moderate genetic differentiation among them. There was a greater affinity of Occidentalis grape to wild grape from the Caucasus than other groups. However, a number of low to moderate frequency alleles that are present in the cultivated grape are not represented in the wild grape.

A study was conducted to quantify the role of long-term grazing management to affect CO2 efflux within the semiarid northern Great Plains of North America. Grazing management systems evaluated in the study included two native vegetation pastures differing in stocking rate [moderately grazed pasture (MGP), heavily grazed pasture (HGP)] and a fertilized, grazed crested wheatgrass [Agropyron desertorum (Fisch.ex.Link) Schult.] pasture (CWP) near Mandan, ND, USA. Carbon dioxide efflux was measured on 1-2 week intervals for three years using static chamber methodology. Supplemental assessments of soil temperature and water content, aboveground live biomass, root biomass, and soil microbial biomass C were conducted during each growing season. Carbon dioxide efflux did not differ between native vegetation pastures differing in stocking rate. However, mean hourly CO2 efflux was greater in CWP (100.1 mg C m(-2) h(-1)) than HGP (81.1 mg C m(-2) h(-1))(P=0.03), a result attributed to prevalence of cool-season grass and high available N in CWP. Carbon dioxide efflux differed among grazing treatments during spring (March-May) and fall (September-November), but not winter (December-February) and summer (June-August). Associations between CO2 efflux and abiotic factors were seasonally dependent, with positive associations between efflux and soil temperature during spring (r = 0.71, P <= 0.01) and fall (r = 0.45, P <= 0.01) and efflux and water-filled pore space (WFPS) during summer (r = 0.46, P <= 0.01). in this study, increased stocking rate did not contribute to elevated CO2 efflux within native vegetation pastures. Given strong weather-dependence on grassland productivity, long-term monitoring is necessary to confidently discern grazing management effects on C dynamics. Published by Elsevier B.V. C1 [Liebig, M.

TI CO2 uptake and ecophysiological parameters of the grain crops of midcontinent North America: Estimates from flux tower measurements SO AGRICULTURE ECOSYSTEMS & ENVIRONMENT LA English DT Article DE Net CO2 exchange partitioning; Gross photosynthesis; VPD limitation of photosynthesis; CO2 sink; Maize; Wheat ID NET ECOSYSTEM EXCHANGE; GROSS PRIMARY PRODUCTION; CARBON-DIOXIDE EXCHANGE; LIGHT-RESPONSE PARAMETERS; NO-TILL ECOSYSTEM; UNITED-STATES; USE EFFICIENCY; EDDY COVARIANCE; PRIMARY PRODUCTIVITY; SURFACE-ENERGY AB We analyzed net CO2 exchange data from 13 flux tower sites with 27 site-years of measurements over maize and wheat fields across midcontinent North America. A numerically robust "light-soil temperature-VPD"-based method was used to partition the data into photosynthetic assimilation and ecosystem respiration components. Year-round ecosystem-scale ecophysiological parameters of apparent quantum yield, photosynthetic capacity, convexity of the light response, respiration rate parameters, ecological light-use efficiency, and the curvature of the VPD-response of photosynthesis for maize and wheat crops were numerically identified and interpolated/extrapolated. This allowed us to gap-fill CO2 exchange components and calculate annual totals and budgets. VPD-limitation of photosynthesis was systematically observed in grain crops of the region (occurring from 20 to 120 days during the growing season, depending on site and year), determined by the VPD regime and the numerical value of the curvature parameter of the photosynthesis-VPD-response, sigma(VPD). In 78% of the 27 site-years of observations, annual gross photosynthesis in these crops significantly exceeded ecosystem respiration, resulting in a net ecosystem production of up to 2100 g CO2 m(-2) year(-1). The measurement-based photosynthesis, respiration, and net ecosystem production data, as well as the estimates of the ecophysiological parameters, provide an empirical basis for parameterization and validation of mechanistic models of grain crop production in this economically and ecologically important region of North America.

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

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

The hexane and ethanol extracts were tested for antifungal activity against four species of wood-rot fungi (i.e, Gloeophyllum trabeum, Postia placenta, Trametes versicolor, and Irpex lacteus). Ashe juniper (AJ) gave the highest extract yields (6.60 to 11.27%), followed by Eastern red cedar (ERC) (4.78 to 9.56%), and then Western juniper (WJ) (4.26 to 7.32%). WJ contained the highest level of cedrol (over 60%), while AJ contained the highest level of thujopsene (over 30%). Methanol and ethanol gave the highest extract yields as well as slightly higher percentages of cedrol and widdrol. The juniper extracts were more effective against white-rot fungi than brown-rot fungi. The ethanol extracts had higher antifungal activity than the hexane extracts. The AJ extracts had the greatest bioactivity against the wood-rot fungi. C1 [Tumen, Ibrahim] Bartin Univ, Fac Forestry, Dept Forest Prod Chem, TR-74100 Bartin, Turkey.

Composites of high density polyethylene (HDPE) composed of 25% by weight DDGS and either 0% or 5% by weight of maleated polyethylene (MAPE) were produced by twin screw compounding and injection molding. An improved DDGS bio-filler was produced by solvent treating DDGS (STDDGS). Injection-molded test specimens were evaluated for their tensile, flexural, impact, and thermal properties. Composite blends composed of STDDGS were superior to their DDSG counterparts. Composites made with STDDGS and MAPE had significantly improved tensile and flexural properties compared to neat HDPE. Impact strength of all composites was similar and lower than neat HDPE. Soaking of tensile bars of the various PE-DDGS blends in distilled water for 28 days altered their physical, color, and mechanical properties. Differential scanning calorimetery and thermogravimetric analysis were conducted on neat HDPE and DDGS composites to evaluate their thermal properties.

The apparatus applies a known displacement to a cantilever beam, measures its static load, then releases it into its natural first mode of transverse vibration. Free vibrational tip displacements as a function of time were recorded. This paper compares the test results from the cantilever beam static bending and vibration with standard midpoint simply supported bending samples. Medium density fiberboard panels were obtained from four different commercial sources. Comparisons were made using a set of fiberboard panels with thicknesses of 8.1, 4.5, 3.7, and 2.6 mm and nominal densities of 700, 770, 780, and 830 kg/m(3), respectively. Cantilever beam static modulus and dynamic modulus of elasticity linearly correlated well but were consistently higher than standard mid-point bending modulus of elasticity having linear correlations of 1.12:1 and 1.26:1, respectively. The higher strain rates of both the static and vibrating cantilever beam could be the primary reason for the slightly higher dynamic modulus values. The log decrement of the displacement was also used to calculate the damping ratio for the cantilever beam. As expected, damping ratio had a slightly decreasing slope as density increased. This paper discusses the new apparatus and initial results. C1 [Hunt, John F.] USDA, Forest Prod Lab, Madison, WI 53726 USA.

Tests were carried out to compare and evaluate the property of bamboo and rice straw pellets, rice straw being the other main source of biomass solid fuel in China. All physical properties of untreated bamboo pellets (UBP), untreated rice straw pellets (URP), carbonized bamboo pellets (CBP), and carbonized rice straw pellets (CRP) met the requirements of Pellet Fuels Institute Standard Specification for Residential/Commercial Densified including dimension, density, and strength. The inorganic ash (15.94 %) and gross heat value (15375 J/g) of rice straw pellets could not meet the requirement of Pellet Fuels Institute Standard Specification for Residential/Commercial Densified (<= 6.0% for PFI Utility) and the minimum requirement for making commercial pellets of DIN 51731 (> 17500 J/g), respectively. Rice straw pellets have been a main type of biomass solid fuel and widely used. Bamboo pellets have better combustion properties compared with rice straw pellets. It is confirmed that bamboo pellets have great potential as biomass solid fuel, especially with respect to development of commercial pellets on an industrial scale in China. The information provided by this research is useful for development and utilization of bamboo resource and pellets.

The IFN-induced protein with tetratricopeptide repeats (IFITs) family is among hundreds of IFN-stimulated genes. This family contains a cluster of duplicated loci. Most mammals have IFIT1, IFIT2, IFIT3 and IFIT5; however, bird, marsupial, frog and fish have only IFIT5. Regardless of species, IFIT5 is always adjacent to SLC16A12. IFIT family genes are predominantly induced by type I and type III interferons and are regulated by the pattern recognition and the JAK-STAT signaling pathway. IFIT family proteins are involved in many processes in response to viral infection. However, some viruses can escape the antiviral functions of the IFIT family by suppressing IFIT family genes expression or methylation of 5' cap of viral molecules. In addition, the variants of IFIT family genes could significantly influence the outcome of hepatitis C virus (HCV) therapy. We believe that our current review provides a comprehensive picture for the community to understand the structure and function of IFIT family genes in response to pathogens in human, as well as in animals.

TI Permittivities of Watermelon Pulp and Juice and Correlation with Quality Indicators SO INTERNATIONAL JOURNAL OF FOOD PROPERTIES LA English DT Article DE Watermelon; Pulp; Juice; Permittivities; Dielectric constant; Loss factor; Soluble solids content; pH; Sugar acid ratio ID DIELECTRIC-SPECTROSCOPY AB Permittivities from 10 to 4500 MHz at 24 degrees C were measured on pulp and juice of watermelons of different maturities with an open-ended coaxial-line probe and network analyzer. The dielectric constant of both materials decreased monotonically with increasing frequency and loss factor had a minimum at about 1000 MHz. Moreover, the pulp and juice had very similar loss factor values at each frequency. Ionic conduction is the major loss mechanism at lower frequencies in this range, while dipolar losses are dominant at the higher frequencies. The best linear coefficients of determination, 0.8 and 0.69, were found at 4500 MHz for correlations between the loss tangent of juice and soluble solids content and between loss tangent of juice and soluble solids content/pH, respectively. The penetration depth of electromagnetic energy in pulp and juice at 4500 MHz was 4 mm. The study offers useful information in assessing watermelon quality from dielectric properties.

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

Applying radiometric change detection techniques we sought to determine whether: (1) differences between pre- and post-growing season spectral vegetation index values effectively identify areas of significant change in vegetation; and (2) areas of significant change coincide with altered ecological states. We differenced NDVI values, standardized difference values to Z-scores to identify areas of significant increase and decrease in NDVI, and examined the ecological states associated with these areas. The vegetation index differencing method and translation of growing season NDVI to Z-scores permit examination of change over large areas and can be applied by non-experts. This method identified areas with potential for vegetation/ecological state transition and serves to guide field reconnaissance efforts that may ultimately inform land management decisions for millions of acres of federal lands.

TI Effect of aerosols and NO2 concentration on ultraviolet actinic flux near Mexico City during MILAGRO: measurements and model calculations SO ATMOSPHERIC CHEMISTRY AND PHYSICS LA English DT Article ID PHOTOCHEMICAL SMOG; PHOTOLYSIS RATES; OZONE PRODUCTION; CLOUDY ATMOSPHERES; RADIATIVE-TRANSFER; METROPOLITAN-AREA; NITROGEN-OXIDES; 2006 CAMPAIGN; URBAN; SENSITIVITY AB Urban air pollution absorbs and scatters solar ultraviolet (UV) radiation, and thus has a potentially large effect on tropospheric photochemical rates. We present the first detailed comparison between actinic fluxes (AF) in the wavelength range 330-420 nm measured in highly polluted conditions and simulated with the Tropospheric Ultraviolet-Visible (TUV) model. Measurements were made during the MILAGRO campaign near Mexico City in March 2006, at a ground-based station near Mexico City (the T1 supersite) and from the NSF/NCAR C-130 aircraft. At the surface, measured AF values are typically smaller than the model by up to 25% in the morning, 10% at noon, and 40% in the afternoon, for pollution-free and cloud-free conditions. When measurements of PBL height, NO2 concentration and aerosols optical properties are included in the model, the agreement improves to within +/- 10% in the morning and afternoon, and +/- 3% at noon. Based on daily averages, aerosols account for 68% and NO2 for 25% of AF reductions observed at the surface. Several overpasses from the C-130 aircraft provided the opportunity to examine the AF perturbations aloft, and also show better agreement with the model when aerosol and NO2 effects are included above and below the flight altitude. TUV model simulations show that the vertical structure of the actinic flux is sensitive to the choice of the aerosol single scattering albedo (SSA) at UV wavelengths. Typically, aerosols enhance AF above the PBL and reduce AF near the surface. However, for highly scattering aerosols (SSA > 0.95), enhancements can penetrate well into the PBL, while for strongly absorbing aerosols (SSA < 0.6) reductions in AF are computed in the free troposphere as well as in the PBL. Additional measurements of the SSA at these wavelengths are needed to better constrain the effect of aerosols on the vertical structure of the AF. C1 [Palancar, G. G.; Hall, S.

However, many knowledge gaps still remain in predicting the fate and transport of pathogens in runoff water, and then through the shallow vadose zone and groundwater. A number of transport pathways, processes, factors, and mathematical models often are needed to describe pathogen fate in agricultural settings. The level of complexity is dramatically enhanced by soil heterogeneity, as well as by temporal variability in temperature, water inputs, and pathogen sources. There is substantial variability in pathogen migration pathways, leading to changes in the dominant processes that control pathogen transport over different spatial and temporal scales. For example, intense rainfall events can generate runoff and preferential flow that can rapidly transport pathogens. Pathogens that survive for extended periods of time have a greatly enhanced probability of remaining viable when subjected to such rapid-transport events. Conversely, in dry seasons, pathogen transport depends more strongly on retention at diverse environmental surfaces controlled by a multitude of coupled physical, chemical, and microbiological factors. These interactions are incompletely characterized, leading to a lack of consensus on the proper mathematical framework to model pathogen transport even at the column scale. In addition, little is known about how to quantify transport and survival parameters at the scale of agricultural fields or watersheds. This review summarizes current conceptual and quantitative models for pathogen transport and fate in agricultural settings over a wide range of spatial and temporal scales. The authors also discuss the benefits that can be realized by improved modeling, and potential treatments to mitigate the risk of waterborne disease transmission.

Here, 480 F-2 plants, derived from three hard spring wheat populations were used to test the segregation of Puroindoline b-2 (Pinb-2) variants 2 and 3. Chi-square analysis indicated that Pinb-2 variants 2 and 3 in all three F-2 populations segregated as a single bi-allelic locus, with segregation ratios fitting a 1:2:1 ratio. Using 448 of the 480 plants derived from these three F-2 populations, the average SKCS hardness index of plants homozygous for Pinb-2 variant 2 vs. those homozygous for variant 3 was not significantly different (67.5 vs. 67.9). Results indicated that plants with Pina-D1b/Pinb-D1a were on average 10.0 Single Kernel Characterization System (SKCS) hardness index units harder than those carrying the Pina-D1a/Pinb-D1b haplotype. In conclusion, Pinb-2 variants 2 and 3 are allelic and exert little effect on kernel texture in hard-kernel T. aestivum germplasm. Further, the designation of Pinb-2v2 and Pinb-2v3 should be changed to Pinb-B2a and Pinb-B2b, respectively. We propose that Pinb-2 variants 1 and 4 of Chinese Spring be designated Pinb-D2a and Pinb-A2a, respectively. Published by Elsevier Ltd.

Tocols are comprised of two subgroups, tocopherols and tocotrienols. Due to their potent antioxidant properties, attention has been given to the health benefits of tocols in oats. However, little is known about developmental aspects of their accumulation. Moreover, aside from their role in protecting membranes from oxidative damage, their possible physiological roles in planta have largely gone uninvestigated. In this study, we quantified tocol accumulation at five time points during oat seed development, and also compared tocol concentration and composition in the whole seed both to endosperm and embryos at a late stage of seed development. The temporal pattern of accumulation of the tocol subgroups was different. Both tocotrienols and tocopherols steadily increased over the course of seed development; however, tocotrienol progression was sigmoidal and tocopherol linear. By the end of seed development, tocotrienols were the most abundant tocol both in whole seed and in seed with embryos removed. In contrast, embryos contained higher concentrations of tocopherols than tocotrienols late in seed development. Differences in both temporal and spatial distribution during seed development suggest distinct roles for tocotrienols and tocopherols. Published by Elsevier Ltd.

The implementation of air quality regulations in livestock-producing states increases the need for accurate on-farm determination of emission rates. Our objective was to determine the emission rates of NH3, CH4, and N2O from the open-freestall and wastewater pond source areas on a commercial dairy in southern Idaho using a flush system with anaerobic digestion. Gas concentrations and wind statistics were measured and used with an inverse dispersion model to calculate emission rates. Average emissions per cow per day from the open-freestall source area were 0.08 kg NH3, 0.41 kg CH4, and 0.02 kg N2O. Average emissions from the wastewater ponds (g m(-2) d(-1)) were 6.8 NH3, 22 CH4, and 0.2 N2O. The combined emissions on a per cow per day basis from the open-freestall and wastewater pond areas averaged 0.20 kg NH3 and 0.75 kg CH4. Combined N2O emissions were not calculated due to limited available data. The wastewater ponds were the greatest source of total farm NH3 emissions (67%) in spring and summer. The emissions of CH4 were approximately equal from the two source areas in spring and summer. During the late fall and winter months, the open-freestall area constituted the greatest source area of NH3 and CH4 emissions. Data from this study can be used to develop trace gas emissions factors from open-freestall dairies in southern Idaho and other open-freestall production systems in similar climatic regions.

Four bedded packs of each bedding material were maintained for two 6-wk periods (N = 64). Straight-and branched-chained fatty acids and aromatic compounds were measured. Corn cob bedding had the highest concentration of odorous VOC, and wood shavings had the lowest (P < 0.01). Calculated odor activity values were highest for corn cob bedding and shredded paper and lowest for wood shavings (P < 0.01). Escherichia coli concentrations decreased from week to week for all treatments from Week 2 to Week 6. At Week 6, E. coli levels in bedded packs with shredded paper were higher (P < 0.05) than bedded packs containing wood shavings, wood chips, or switchgrass (P < 0.05). At Weeks 4, 5, and 6, E. coli concentrations in bedded packs with wood shavings were lower (P < 0.05) than bedded packs of all treatments except wood chips. Results of this study indicate that ground corn cobs or shredded paper may increase odor production and shredded paper may increase E. coli when used in deep-bedded livestock facilities, whereas wood shavings may have the least impact on air quality and E. coli.

Thus, we designed a laboratory flow cell and experimental procedures to quantify the chemical transport from soil to runoff water in the following individual processes: (i) convection with a vertical hydraulic gradient, (ii) convection via surface flow or the Bernoulli effect, (iii) diffusion, and (iv) soil loss. We applied different vertical hydraulic gradients by setting the flow cell to generate different seepage or drainage conditions. Our data confirmed the general form of the convection-diffusion equation. However, we now have additional quantitative data that describe the contribution of each individual chemical loading process in different surface runoff and soil hydrological conditions. The results of this study will be useful for enhancing our understanding of different geochemical processes in the surface soil mixing zone.

TI Reduced Nitrogen Losses after Conversion of Row Crop Agriculture to Perennial Biofuel Crops SO JOURNAL OF ENVIRONMENTAL QUALITY LA English DT Article ID CONSERVATION RESERVE PROGRAM; MISSISSIPPI RIVER-BASIN; ION-EXCHANGE-RESIN; CENTRAL ILLINOIS; BIOENERGY FEEDSTOCK; COLD TOLERANCE; ORGANIC-CARBON; CLIMATE-CHANGE; ENERGY CROP; NITRATE AB Current biofuel feedstock crops such as corn lead to large environmental losses of N through nitrate leaching and N2O emissions; second-generation cellulosic crops have the potential to reduce these N losses. We measured N losses and cycling in establishing miscanthus (Miscanthus x giganteus), switchgrass (Panicum virgatum L. fertilized with 56 kg N ha(-1) yr(-1)), and mixed prairie, along with a corn (Zea mays L.)-corn-soybean [Glycine max (L.) Merr.] rotation (corn fertilized at 168-202 kg N ha(-1)). Nitrous oxide emissions, soil N mineralization, mid-profile nitrate leaching, and tile flow and nitrate concentrations were measured. Perennial crops quickly reduced nitrate leaching at a 50-cm soil depth as well as concentrations and loads from the tile systems (year 1 tile nitrate concentrations of 10-15 mg N L-1 declined significantly by year 4 in all perennial crops to <0.6 mg N L-1, with losses of <0.8 kg N ha(-1) yr(-1)). Nitrous oxide emissions were 2.2 to 7.7 kg N ha(-1) yr(-1) in the corn-corn-soybean rotation but were <1.0 kg N ha(-1) yr(-1) by year 4 in the perennial crops. Overall N balances (atmospheric deposition + fertilization + soybean N-2 fixation - harvest, leaching losses, and N2O emissions) were positive for corn and soybean (22 kg N ha(-1) yr(-1)) as well as switchgrass (9.7 kg N ha(-1) yr(-1)) but were -18 and -29 kg N ha(-1) yr(-1) for prairie and miscanthus, respectively. Our results demonstrate rapid tightening of the N cycle as perennial biofuel crops established on a rich Mollisol soil.

TI Runoff Quality from No-Till Cotton Fertilized with Broiler Litter in Subsurface Bands SO JOURNAL OF ENVIRONMENTAL QUALITY LA English DT Article ID APPLIED POULTRY LITTER; LIQUID SWINE MANURE; PHOSPHORUS RUNOFF; WATER-QUALITY; AGRICULTURAL PHOSPHORUS; SIMULATED RAINFALL; NUTRIENT LOSSES; SEDIMENT LOSSES; SURFACE WATERS; SOIL AB Surface broadcast of broiler litter to no-till row crops exposes the litter and its nutrients to risks of loss in runoff water and volatilization and may limit the potential benefit of litter to the crops. Subsurface banding of litter could alleviate these risks. A field study was conducted in 2008 and 2009 on an upland Falkner silt loam soil to determine the effect of broiler litter placement on runoff nutrient losses from no-till cotton (Gossypium hirsutum L.). Treatments included surface broadcast broiler litter applied manually, subsurface-banded litter applied by tractor-drawn equipment, and no broiler litter, all in combination with or without winter wheat (Triticum aestivum L.) cover crop residue. Broiler litter rate was 5.6 Mg ha(-1). The experimental design was a randomized complete block with a split-plot arrangement of treatments replicated three times. In 2008, simulated rainfall was used to generate runoff 27 d after litter application. Subsurface-banded litter reduced runoff total C, N, P, NH4, NO3, Cu, Zn and water-soluble P (WP) concentrations by 72, 64, 51, 49, 70, 36, 65, and 77%, respectively, compared with surface broadcast. The reductions were greater in 2009 where runoff occurred 1 d after litter application. Bacterial runoff was decreased by one log with subsurface-banded litter compared to surface broadcast. Except for C, NH4+, N, and WP, the presence of winter cover crop residue did not affect the load or runoff nutrient concentrations in either year. The results indicate that subsurface banding litter to no-till cotton substantially reduces nutrient and bacterial losses in runoff compared with surface broadcasting.

An optimized purification method was then used to identify and quantify the proanthocyanidins (extension and terminal units of epigallocatechin, catechin, epicatechin, A type trimer, and A type dimer) of commercially available cranberry products (juices, concentrates, tablets, and capsules; n = 17). Two size exclusion beads (Toyopearl 4 TSK HW-40C and Sephadex LH-20) were found suitable for proanthocyanidin purification, though proanthocyanidin extension and terminal unit composition was contingent upon the cleanup procedure utilized. These data illustrate that purification methods require consideration prior to conducting any cranberry proanthocyanidin analyses, and have to be accounted for when comparing values between studies. Total proanthocyanidin levels ranged from 11.7 (juice) to 436.4 (tablet) mg/100 mL or 100 g values obtained from Sephadex LH-20 purification, while total anthocyanin levels ranged from 0.54 (juice) to 98.00 (tablet) mg/100 mL or 100 g.

The free radical scavenging activity of ECH was evaluated by ABTS and DPPH assay. Phenolic compounds like luteolin 7-o-glucoronide, apigenin 7-o-glucoronide and chrysoerisol 7-o-glucoronide were identified in ECH by UPLC-MS/MSn analysis. On the other hand, the anti mutagenic effect of ECH was examined using tester strain Salmonella typhimurium TA100 with and without S9 extract. CCl4 administered Wistar rats exhibited alteration in various biochemical parameters which were significantly (P <= 0.05) restored toward normal level by the therapy of ECH. ECH significantly (P <= 0.05) reduced LPO level in the liver tissue. Treatment with ECH showed curative effect on histopathological alterations and DNA damage in CCl4 administered rats in a dose dependent manner. Silymarin, a routine hepatoprotective drug was used as reference standard. (C) 2012 Elsevier Ltd. All rights reserved.

Can thinning of overstorey trees and planting of native tree saplings increase the establishment of native trees in exotic Acacia plantations in South China? Assessing the effect of thinning of overstorey trees and planting of native trees will be helpful to better understand the vegetation restoration. A stand conversion experiment was conducted in a 12-year-old Acacia auriculiformis plantation in 1996. Treatments were thinning and underplanting, underplandng, thinning, and control. Results showed that thinning enhanced the establishment and growth of underplanted and regenerated native seedlings. The thinning and underplanting treatment reduced soil organic matter, soil total nitrogen, soil bulk density and soil water content but increased soil phosphorus and potassium contents. The establishment and growth of underplanted native species depended on their responses to light and soil resources. Thinning increased recolonisation by native species. Since some of the underplanted native trees grow rapidly, the regenerating canopy cover can become dense after thinning, and the density of the new canopy inhibits regeneration of other native tree species. Therefore, moderate thinning should be periodically performed as part of the long-term management of plantation and different thinning intensities can be used to increase spatial variability in the overstorey. The shade tolerance of native species was the most important characteristic in determining the response of the native trees to the treatments. C1 [Yuan, S.

TI Molecular properties of potato spindle tuber viroid (PSTVd) isolates of the Russian Research Institute of Phytopathology SO MOLECULAR BIOLOGY LA English DT Article DE Potato spindle tuber viroid (PSTVd); viroid primary and secondary structure; viroid pathogenicity; mutation frequency ID NUCLEOTIDE-SEQUENCE; MILD STRAIN; RNA AB The complete nucleotide sequences of more than 100 isolates of Potato spindle tuber viroid (PSTVd) collected from locations in the territory of Russia and the former USSR have been determined. These sequences represent 43 individual sequence variants, each containing 1-10 mutations with respect to the "intermediate" or type strain of PSTVd (GenBank Acc. No. V01465). Isolates containing 2-5 mutations were the most common, and 24 sequence variants are described here for the first time. Twenty one isolates contained a mutation found only in Russian and Ukrainian isolates of PSTVd up till now; i.e., replacement of the adenine at position 121 with cytosine (A121C). Many of these isolates contained two mutations-deletion of one of three adenine residues occupying positions 118-120 plus replacement of the adenine at position 121 with either uracil or cytosine (-A120, A121U/C). Both combinations of mutations were phenotypically neutral, i.e. symptom expression in Rutgers tomato was unaffected. Phylogenetic analysis of the sequences of different PSTVd isolates presented in work together with sequences of other naturally-occurring isolates obtained from Internet databases suggesting that known PSTVd isolates may be divided into four groups: (i) a group of isolates from potato and ornamentals where the type strain of PSTVd (PSTVd.018) may be considered to represent the ancestral sequence, (ii) a second group of isolates from potato and ornamentals where PSTVd.123 play the same role as PSTVd.018 for the first group, and iii) a group of potato isolates where PSTVd.125 is a possible ancestral sequence. The fourth and most divergent group of PSTVd isolates differs significantly from these first three groups. The majority of isolates in this group originate from New Zealand and Australia and infect different solanaceous hosts (tomato, pepper, cape gooseberry, potato, and others). C1 [Kastalyeva, T.

TI Effect of multiple extrusion passes on zein SO POLYMER DEGRADATION AND STABILITY LA English DT Article DE Zein; Degradation; Thermal degradation; Extrusion ID CIRCULAR-DICHROISM; DEGRADATION; TEMPERATURE; SECONDARY; PROTEINS; MAIZE AB Zein was processed up to seven times using a single screw extruder at a temperature of 145 degrees C and at approximately 15 g per minute to determine the extent of degradation that occurs with multiple extrusion passes. SDS-PAGE shows that with the second pass, and each additional pass, the amount of high molecular weight material increases. Given that a reducing agent reduces the molecular weight of the protein, then this increased molecular weight is predominantly due to disulfide bond formation between proteins. Examination of the secondary structure of the protein using far-UV CD illustrated that after the third pass there was a significant reduction in the amount of alpha-helix and beta-sheet content. Examining the near-UV CD spectra, which reflects changes in protein tertiary structure, illustrates significant changes in structure after the first and second pass through the extruder. IR and NMR spectroscopy revealed small differences with multiple passes through the extruder. Examining color using the delta E scale displays a change in color after four extrusion passes. The physical properties of compression molded samples from each pass are similar with statistical differences being observed only in modulus. While some changes in zein properties can be observed with multiple extrusion passes, if physical properties are of the highest importance, than zein can be processed at least seven times and still provide a quality material.

The aim of this study was to quantify the role of increasing drought on weed-induced crop losses and cropweed interactions for processing tomato grown in southern Italy. Field experiments were carried out during 2008 and 2009. Two levels of water availability were imposed to compare weed competitive effects under irrigated and rainfed conditions on tomato as a means to quantify weedcrop interactions and associated crop losses when water is limited. In this study, the absolute decline in tomato yields by weed interference was a direct function of water applied (rain + irrigation); however, the relative effect of weed biomass on crop loss appeared to increase under drought when compared to irrigated conditions. Overall, these data indicate that the relative decline in tomato fresh weight from weeds was actually greater under drought, and that the relative crop losses (per unit of weed biomass) actually declined as water availability increased. From a management standpoint, these data suggest that if drought occurrences do increase in the Mediterranean region with climate change, there may be a greater need for complete and thorough weed control for this production system.

This study investigated the predictive capability of the K-value estimated by Universal Soil Loss Equation (USLE), Revised Universal Soil Loss Equation (RUSLE), Erosion Productivity Impact Calculator (EPIC) and Dg models for different soil regions using a Chinese soil erodibility database covering 51 natural runoff plots. Model performance was evaluated using R 2 (coefficient of determination), relative error (RE), NashSutcliff efficiency (NSE) and P value (MannWhitney U test) statistics. The results showed that the existing four models overestimated almost all the K-values for the Chinese erodibility database, with most observed values concentrated in the range of 0.0150.035. Without calibration, only the USLE and Dg models could be reliable and directly applied for the black soil region and the loess soil region, respectively. The DgOM model (R 2=0.67, n=32) was established by the non-linear best fitting techniques of multiple regression. In the DgOM model, K-values accounted for the vibration in a combination of the D g (geometric mean diameter) and OM (soil organic matter). NSE, R 2 and the average RE was 0.94, 0.67 and 9.5% for the DgOM model's calibration based on the Chinese erodibility database; similar results were found for the validation process, with NSE of 0.93, R 2 of 0.66 and average RE of 6.5%. The model performances showed that the DgOM model reached good' satisfactory level. Compared with the four existing erodibility models, the DgOM model permitted the best parameterization and accuracy, and was proved to be suitable for estimating soil erodibility values in China.

In this study, a small field plot technique for controlling soil moisture content suitable for physiological research in moist, humid areas was tested. We characterized the effect of water stress on total leaf conductance (g(l)) for two distinct determinate soybean [Glycine max (L.) Merr.] genotypes. Based on these findings, a model of g(l) as a function of plant age and soil moisture content was formulated and validated. The dependency of g(l) on plant age was well represented by a parabolic function that increased throughout the vegetative period, peaked around anthesis, and decreased throughout the reproductive period and senescence. A sigmoidal function explained the relation of g(l) to plant-available soil water content. This new empirical model effectively quantifies the response of g(l) to plant-available soil water and plant age with a functional form similar to the abscisic acid related Tardieu-Davies model.

The objectives of this study were: (i) to quantify the effects of crop management practices and tillage on soil water and spring wheat (Triticum aestivum L.) production in a continuous spring wheat system using the RZWQM2 model (coupled with CERES-Wheat) under a dryland condition, and (ii) to extend the RZWQM2 model results to longer term weather conditions and propose alternate cropping systems and management practices. Measured soil water content, yield, and total aboveground biomass under different tillage and plant management practices were used to calibrate and evaluate the RZWQM2 model. The model showed no impacts of tillage but late planting greatly reduced grain yield and biomass, in agreement with observed differences among treatments. The hydrologic analysis under long-term climate variability showed a large water deficit (32.3 cm) for spring wheat. Fallowing the cropland every other year conserved 4.2 cm of water for the following wheat year, of which only 1.7 cm water was taken up by wheat, resulting in a yield increase of 249 kg ha(-1) (13.7%); however, the annualized mean yield decreased 782 kg ha(-1) (43.1%) due to 1 yr of fallow. Other long-term simulations showed that optimal planting dates ranged from 1 March to 10 April and the seeding rates with optimum economic return were 3.71 and 3.95 x 10(6) seeds ha(-1) for conventional and ecological management treatments, respectively.

TI Steer Performance and Pasture Productivity among Five Perennial Warm-Season Grasses SO AGRONOMY JOURNAL LA English DT Article ID GROWING BEEF STEERS; 3 FORAGE MASSES; BIG BLUESTEM; TIFTON-85 BERMUDAGRASS; CAUCASIAN BLUESTEM; GRAZING BEHAVIOR; TALL FESCUE; COASTAL; SWITCHGRASS; YIELD AB Grazing systems in the mid-Atlantic region of the United States typically utilize perennial warm-season grasses. Bermudagrass [Cynodon dactylon (L.) Pers.] has served this function in the region, but the resulting animal performance has been modest. Steer and pasture performance of three native grasses, big bluestem (BBS) (Andropogon gerardii Vitman), eastern gamagrass (GG) (Tripsacum dactyloides L.), and switchgrass (SG) (Panicum virgatum L.), and an introduced Old World bluestem, Caucasian bluestem (CBS) [Bothriochloa bladhii (Retz.) S. T. Blake], were compared during 6 yr with Tifton 44 bermudagrass (BG) as the control. During summer (June-September), steers continuously stocked on the alternative grasses gained similarly (0.73 kg d(-1)) but more rapidly than those grazing BG (0.49 kg d(-1)). Stocking of BG at 9.9 steers ha(-1) was greater than the alternative grasses (5.7 steers ha(-1)), which were similar. Although animal days per hectare were greater for BG, weight gain per hectare was similar (mean = 357 kg ha(-1)) because of the differential gain per day. Canopies of BG and CBS had the least proportion of their mass in leaf (24.5 and 25.0%, respectively) compared with GG (58.2%), BBS (35.6%), and SG (30.9%), with the latter two similar. In general, any one of the grasses can serve as the warm-season component; however, pastures of BBS, GG, SG, and CBS would be more appropriate for growing ruminants, although at a reduced stocking rate, than BG. The latter would provide adequate forage for mature animals. C1 [Burns, J. C.] N Carolina State Univ, USDA, ARS, Dep Crop Sci, Raleigh, NC 27695 USA. [Burns, J.

The cotton growth simulation model Cotton2K was used to simulate the lint yield of cotton for different amounts of available irrigation water using historic weather data for the last 110 yr in the Texas High Plains. The data generated were used to evaluate different field partitioning strategies at four different amounts of total available irrigation water (150, 225, 300, and 375 mm). The results revealed that irrigating 30, 45, 55, and 70% of the field were the best strategies to maximize both the lint yield and profit under 150, 225, 300, and 375 mm of available irrigation water, respectively. The field partitioning strategies had a more pronounced impact on effective lint yield and profit when lower amounts of irrigation water were available and under low-rainfall conditions.

TI Nitrogen Fertilization Effect on Soil Water and Wheat Yield in the Chinese Loess Plateau SO AGRONOMY JOURNAL LA English DT Article ID PRECIPITATION STORAGE EFFICIENCY; WINTER-WHEAT; GRAIN-YIELD; DRYLAND; CROP; TILLAGE; SYSTEMS; FERTILITY; SORGHUM; BALANCE AB Long-term N fertilization may increase dryland winter wheat (Triticum aestivum L.) yield but also result in adverse effects, e.g., soil acidity development and water storage or increased N leaching. This study examined if long-term N fertilization affected the soil water balance and dryland winter wheat yield. We evaluated the effect of five N fertilization rates (0, 45, 90, 135, and 180 kg N ha(-1)) on the soil water balance, precipitation-storage efficiency (PSE), winter wheat yield, and water-use efficiency (WUE) from 2005 to 2010 in an experiment initiated in 1984 in a Heilutu silt loam in the Loess Plateau of China. Soil water contents at wheat planting and harvest were lower with N fertilization than without. Nitrogen fertilization increased soil water storage during the fallow period (SWSF) from 19 to 22%, water uptake during the growing season from 21 to 25%, PSE from 19 to 22%, and evapotranspiration from 7 to 8% compared to no N fertilization. Increased N rate enhanced soil organic C but had no impact on soil pH in 2005. Wheat yield increased up to 244% and WUE to 220% as the N rate increased. Although more soil water was depleted, N fertilization increased winter wheat yield and WUE by enhancing SWSF and PSE, and increased the water holding capacity by increasing soil organic matter compared to no N fertilization. Long-term N fertilization can increase winter wheat yield by utilizing soil water more efficiently, with minimum impact on soil acidity, in the Chinese Loess Plateau.

Shoot residue quality and soil mineral N following incorporation of rye (Secale cereale L.), legume-rye, and mustard CCs was determined in December to February or March during the first 8 yr of the Salinas Organic Cropping Systems trial in Salinas, CA. Legume-rye included Vicia faba L., V. sativa L., V. benghalensis L., Pisum sativum L., and rye; mustard included Sinapis alba L. and Brassica juncea Czern. Cover crops were planted in the fall at standard and three times higher seeding rates (SRs) before vegetables annually. Significant CC x year interactions occurred for C and N concentrations and C/N ratios of CC shoots. In general, C concentrations were higher in rye and legume-rye, N concentrations were higher in mustard and legume-rye, and C/N ratios were higher in rye. During the season, C concentrations and C/N ratios tended to increase, whereas N concentrations decreased. Compared with rye and mustard, legume-rye residue quality changed least during each season. Increasing the SR reduced N concentrations and increased C/N ratios; however, the effect varied with time and by residue. Following CC incorporation, soil mineral N varied between years and CC and was typically highest following legume-rye or mustard and lowest without CC. Rainfall aft er CC incorporation reduced soil N one year, suggesting that leaching occurred. We conclude that mustard and legume-rye produce higher quality residue that will decompose more rapidly and minimize tillage challenges for subsequent vegetables but may be more prone to post-incorporation N leaching.

TI First-Year Corn after Alfalfa Showed No Response to Fertilizer Nitrogen under No-Tillage SO AGRONOMY JOURNAL LA English DT Article ID SOIL-NITROGEN; NITRATE TEST; AVAILABILITY AB Although fertilizer N response of first-year corn (Zea mays L.) following alfalfa (Medicago sativa L.) has been reported for more than 350 site-years of research, N responses under no-tillage have been reported for only 17 site-years. To determine the rate of N fertilizer required for first-year corn aft er alfalfa in no-tillage systems, on-farm experiments were conducted at seven locations in southern Minnesota and southwestern Wisconsin. The accuracy of the presidedress soil nitrate test (PSNT) and basal stalk nitrate test (BSNT) to identify the need for supplemental N in first-year, no-tillage corn also was evaluated. Across seven site-years, no yield response to fertilizer N was observed for corn grain, cob, stover, or silage yield, confirming that alfalfa N credits can supply the entire N requirement of no-tillage corn following alfalfa. Critical levels of PSNT used in other U. S. Corn Belt states, incorrectly predicted responses to supplemental N at all six locations where PSNT was measured (soil NO3-N concentrations were <= 18 mg kg(-1)), suggesting that critical levels may need to be reduced in no-tillage corn following alfalfa. In this first report under no-tillage conditions, the BSNT concentrations in nonfertilized corn aft er alfalfa were in the marginal range at two locations (between 250 and 700 mg NO3-N kg(-1)) and optimum or above at the other five locations, indicating that the BSNT incorrectly characterized N supply in two of seven cases.

TI Estimates of Agrilus planipennis Infestation Rates and Potential Survival of Ash SO AMERICAN MIDLAND NATURALIST LA English DT Article ID BORER COLEOPTERA; NORTH-AMERICA; BUPRESTIDAE; SCOLYTIDAE; TREE; ATTACKS; DENSITY; FOREST; BEETLE AB The invasive forest pest, Agrilus planipennis (emerald ash borer, Coleoptera: Buprestidae), has caused significant mortality of ash (Fraxinus spp.) in southeastern Michigan, USA, where this pest is thought to have been originally introduced into North America. Phloem feeding by A. planipennis larvae leads to girdling of the host tree, which has resulted in the death of millions of ash trees in invaded landscapes. A survey of ash over a large geographic area was used to estimate numbers of dead and infested ash at a landscape scale within Indiana, Michigan and Ohio. Over 50 million ash trees infested with A. planipennis were estimated in the study area. This represented less than 20% of the ash trees at this broad landscape scale. We used an aerial survey with digital sketchmapping to identify individual and clusters of ash trees that were potentially alive in Oakland and Wayne Counties, Michigan, where A. planipennis is believed to have been active the longest. Diameters at breast height (DBH) and bark roughness were compared between live trees and the closest dead tree. Over 200 live trees were identified within five Huron-Clinton Metroparks, with 65% of these expressing signs and symptoms of A. planipennis attack. Trees that had succumbed to A. planipennis attack had significantly rougher bark than those trees that had survived, while DBH did not differ between the two groups. The probability of ash mortality increased with increasing bark roughness. Bark roughness provides insight into the potential survival of ash within forests. This case-control study, in addition to the estimates of infestation, establishes a baseline and the need to identify further individual and environmental characteristics that facilitate ash survival in the presence of A. planipennis.

In Jun. 2011, the U.S. Fish and Wildlife Service requested information on the species to review potential listing under the Endangered Species Act. In response, managers at the SNF initiated a survey to determine if a resident population of eastern small-footed bats exists on the forest. We surveyed the SNF within Pope and Johnson Counties from 25 Jul.-16 Aug. 2011 by searching for day roosts under loose rocks on exposed rock outcrops. We discovered 29 individuals, including post lactating females and juveniles, along rock outcrops surrounding the 2005 site. While, the extent of M. leibii occurrence in Illinois is still poorly understood, our survey suggests that a resident breeding population occurs within the southern tip of the state.

TI Presence of two host races of Aphis gossypii Glover (Hemiptera: Aphididae) collected in Turkey SO ANNALS OF APPLIED BIOLOGY LA English DT Article DE Cotton aphid; host adaptation; host change; host races; melon aphid ID COTTON APHID; INSECTICIDE RESISTANCE; LIFE-HISTORY; HOMOPTERA; PLANT; TEMPERATURE; FECUNDITY; SUSCEPTIBILITY; EXPERIENCE; EVOLUTION AB The aphid, Aphis gossypii, is a primary pest of citrus, cotton, cucurbits and greenhouse-grown vegetables in Turkey and throughout Europe. There is some previous empirical data suggesting that host-adapted genotypes of this aphid exist which may in fact be host-races. To determine if host races of A. gossypii are indeed present in the eastern Mediterranean region of Turkey, reciprocal host transfer experiments and life table analyses were performed with multiple asexual lineages (= clones) of the aphid collected from different hosts. The collection hosts included citrus, cucumber, eggplant, okra, sweet pepper and cotton. Aphid developmental times on the host from which the aphid was originally collected (= collection or natal host) were shorter (5.2-6.0 days) and had a higher intrinsic rate of population growth (r(m) = 0.25-0.44) than the 6.6-7.3 days required when the aphid was reared on a non-original collection host (= non-collection host or non-natal host) and had r(m) = 0.03-0.30. Total immature mortality of the cotton clone, especially in the first nymphal stage, was high (51-100%) with low r(m) (0-0.03) on cucumber, citrus and sweet pepper. Aphid populations transferred from citrus, eggplant and okra to cotton (r(m) = 0.29-0.30) did not differ significantly in their performance from that of the cotton population on cotton (r(m) = 0.34), whereas that from sweet pepper and cucumber populations (r(m) = 0.22-0.24) were significantly lower. These data have allowed us to separate A. gossypii into two distinct biological groups: (a) a 'generalist' population obtained from cucumber, sweet pepper, citrus, eggplant and okra which exhibited statistically better development on cotton; versus (b) a population from cotton which, by comparison on reciprocal hosts, developed poorly on non-natal hosts except on eggplant. Development of the cotton clone on cucumber and okra was not improved after four successive generations on the non-natal host. The good development of A. gossypii from eggplant and cotton on these reciprocal hosts suggests that these particular clones were similar, if not identical, host races.

TI Potato purple top phytoplasma-induced disruption of gibberellin homeostasis in tomato plants SO ANNALS OF APPLIED BIOLOGY LA English DT Article DE Big bud; feedback regulation; gibberellin homeostasis; gibberellin metabolism genes; potato purple top phytoplasma; tomato ID TRANSMITTED VIRESCENCE AGENT; FEEDBACK-REGULATION; FUNCTIONAL EXPRESSION; MOLECULAR-CLONING; GENE-EXPRESSION; BIOSYNTHESIS; INFECTION; DEACTIVATION; ARABIDOPSIS; METABOLISM AB Phytoplasmas are phloem-inhabiting, cell wall-less bacteria that cause numerous plant diseases worldwide. Plants infected by phytoplasmas often exhibit various symptoms indicative of hormonal imbalance. In this study, we investigated the effects of potato purple top (PPT) phytoplasma infection on gibberellin homeostasis in tomato plants. We found that PPT phytoplasma infection caused a significant reduction in endogenous levels of gibberellic acid (GA(3)). The decrease in GA(3) content in diseased plants was correlated with down regulation of genes responsible for biosynthesis of bioactive GAs (GA20ox1 and GA3ox1) and genes involved in formation of GA precursors [geranyl diphosphate synthase (GPS) and copalyldiphosphate synthase (CPS)]. Exogenous application of GA(3) at 200 mu mol L-1 was able to restore the GA content in infected plants to levels comparable to those in healthy controls, and to attenuate the characteristic 'big bud' symptoms induced by the phytoplasma. The interesting observation that PPT phytoplasma-infected plants had prolonged low expression of key GA biosynthesis genes GA20ox1 and GA3ox1 under GA deficiency conditions led us to hypothesise that there was a diminished sensitivity of the GA metabolism feedback regulation, especially GA biosynthesis negative feedback regulation, in those affected plants, and such diminished sensitization in early stages of infection may represent a central element of the phytoplasma-induced disruption of GA homeostasis and pathogenesis.

We spatially analyzed the sensitivity of financially feasible biomass volumes for delivery to a bioenergy facility across 16 combinations of delivered biomass and diesel prices for a 515,900 ha area in western Montana. At the lowest delivered biomass price analyzed, $31.52 per oven dried tonne (ODT), 28% of the potential volume was financially feasible at the lowest diesel price, $0.053 L-1, dropping off to 6% of the volume at the highest diesel price analyzed, $1.32 L-1. With a 50% increase in delivered biomass price to $47.28 ODT-1, feasibility increased to 88% at the $0.53 L-1 diesel price, dropping to 36% of the volume at the $1.32 L-1 diesel price. Another 50% increase in delivered biomass price to $63.05 ODT-1 resulted in the feasible volume converging on the total potential volume at the lower diesel prices, and at the highest delivered price, $78.81 ODT-1, nearly all potentially available biomass is financially feasible even at the highest diesel fuel price analyzed. Haul was almost entirely restricted to paved roads closest to the bioenergy facility at the lowest delivered biomass price. As delivered price increased, feasible volume expanded further into areas accessed by unpaved roads as well as paved roads further from the bioenergy facility. Results show that financial feasibility is much more sensitive to changes in delivered biomass prices than diesel prices. Published by Elsevier Ltd.

We compared survival and height growth of planted conifers and density and seral composition of natural regeneration among treatments with differing retention levels (15% versus 40%) and patterns (dispersed versus aggregated) replicated across a range of latitudes and forest zones. We also assessed plot-scale relationships of natural regeneration with overstory density and basal area, competing vegetation, and slash accumulations. Early (1- to 2-year) survival of planted seedlings was greater in dispersed treatments (Pinus monticola Douglas ex D. Don, Abies spp.) or unaffected by retention level or pattern (Pseudotsuga menziesii (Mirb.) Franco). Later (5- to 12-year) survival did not differ (all species), but growth was distinctly reduced in dispersed treatments and (or) at higher levels of retention. Density of natural regeneration was 1.5-2.5 times greater in dispersed treatments than in the cleared areas of aggregated treatments. Low-level dispersed retention promoted Pseudotsuga, the early-seral dominant, presumably by enhancing seed rain within a relatively high-light environment. Dispersed retention favored late-seral conifers. The ability to manipulate retention pattern and level to influence regeneration density and composition provides managers with flexibility in developing structurally complex and compositionally diverse forests.

The optimization model minimizes the expected number of fires that do not receive a standard response-defined as the number of resources by type that must arrive at the fire within a specified time limit-subject to budget and station capacity constraints and uncertainty about the daily number and location of fires. We use the California Fire Economics Simulator to predict the number of fires not contained within initial attack modeling limits. Compared with the current deployment, the deployment obtained with optimization shifts resources from the planning unit with highest fire load to the planning unit with the highest standard response requirements but leaves simulated containment success unchanged. This result suggests that, under the current budget and capacity constraints, a range of deployments may perform equally well in terms of fire containment. Resource deployments that result from relaxing constraints on station capacity achieve greater containment success by encouraging consolidation of resources into stations with high dispatch frequency, thus increasing the probability of resource availability on high fire count days.

TI Quantifying the effect of fuel reduction treatments on fire behavior in boreal forests SO CANADIAN JOURNAL OF FOREST RESEARCH-REVUE CANADIENNE DE RECHERCHE FORESTIERE LA English DT Article ID CHARACTERISTIC CLASSIFICATION-SYSTEM; MIXED-CONIFER FOREST AB Mechanical (e.g., shearblading) and manual (e.g., thinning) fuel treatments have become the preferred strategy of many fire managers and agencies for reducing fire hazard in boreal forests. This study attempts to characterize the effectiveness of four fuel treatments through direct measurement of fire intensity and forest floor consumption during a single prescribed burn. The treatments included (1) thinning trees and removing debris (THIN-REMOVE-1 and -2), (2) thinning trees and burning the debris onsite, (3) shearblading and leaving the debris in place (SHEAR), and (4) shearblading and piling the debris in windrows (SHEAR-ROW). Fire burned through treatments 1, 3, and 4 and one control unit. The highest fire intensities (maximum temperature of 1150 degrees C, maximum heat flux of 227 kW.m(-2), and fire cumulative energy release of 4277 J.m(-2)) were measured in the control. Treatment 1 exhibited a peak temperature of 267 degrees C, peak heating of 16 kW.m(-2), and cumulative energy release of 2600 J.m(-2). Treatments 3 and 4 exhibited peak temperatures of 170 and 66 degrees C, peak heating of 51 and 3 kW.m(-2), and cumulative energy release of 2500 and 1800 J.m(-2), respectively. The thinned treatment showed the most significant impact in the context of reduced heat release. C1 [Butler, B.

Severity of Verticillium wilt varied significantly among mint lines and cultivars in the inoculated and non-inoculated sub-plots in two field trials. Verticillium wilt was significantly less severe for mutant lines 87M0109-1, 84M0107-7, and M90-11 than for Black Mitcham in 2002 and 2003. Verticillium wilt was significantly less severe for mutant line M83-14 and for Murray Mitcham than for Black Mitcham in 2003 and 2004. At the completion of the first trial, fresh hay yields of both peppermint hybrids 87M0109-1 and 84M0107-7 and peppermint mutant M90-11 were significantly higher than the standards Black Mitcham and Redefined Murray Mitcham. Oil yield in the first trial of standard Black Mitcham declined in years 3 and 4, while the decline in oil yield was less dramatic with the other four peppermint lines. In the second trial, hay yields of both B90-9 and M83-14 were comparable to, but not significantly different from Black Mitcham and Redefined Murray Mitcham. Line 92(B-37 x M0110)-1 yielded significantly less oil than all peppermint lines including both standards Black Mitcham and Redefined Murray Mitcham in six of the seven cuttings in the second trial. Verticillium rating of the lines and cultivars inoculated in trials from a previous greenhouse study were highly correlated with the Verticillium wilt rating of the lines and cultivars the second and third years when inoculated in both field nurseries in this study. Verticillium wilt resistance and yield can be improved in commercial mint cultivars and form a basis for managing the disease. (C) 2012 Elsevier Ltd. All rights reserved.

Good agricultural practices (GAPS) are needed to reduce their human health risks, environmental impacts, and improve their cost-effectiveness. This study investigated the effect of fumigant application methods on soil persistence and emission of 1,3-dichloropropene (1,3-D) and chloropicrin (CP). Field experiments were conducted to measure the individual and combined effects of pre-application tillage practices, fumigant application technology, and plastic films on 1,3-D soil concentrations to obtain a numerical index (CT value) to estimate their potential for pest control efficacy and to compare soil persistence, atmospheric flux rate, and cumulative emission of CP and 1,3-D under two diverse application scenarios. Greater 1,3-D soil vapor concentrations were observed by combining a pre-application soil seal with low soil disturbance application technology when compared to pre-application soil tillage and the use of back-swept application shanks. Under high density polyethylene plastic, the low disturbance scenario resulted in time weighted exposure concentration (CT) values ranging from 6.8 to 12.2 mu g h cm(-3) of soil as compared to CT values ranging from 2.9 to 5.4 mu g h cm(-3) under the conventional application scenario. Cumulative atmospheric emission of 1,3-D was decreased by 18% under the low disturbance scenario and atmospheric emission of CP by 21% when compared to a conventional application scenario. This study identified GAPs that can be readily implemented in the field to reduce the human and environmental impacts of soil fumigants and improve their cost-effectiveness under solid-tarp (broadcast) applications.

The recent invasion of the Northern Great Plains by the soybean aphid (Aphis glycines Matsumura; Hemiptera: Aphididae) has had potentially important implications for insect communities in soybeans of this region, although recent descriptions of this regional community are scarce. We describe how three pest management systems that vary in the intensity with which they rely on herbicides and insecticides (chemically intensive, reduced chemical, and spring cover crop treatments) affect insect pest populations, arthropod predator communities, weed assemblages,, and soybean yield and profitability. Soybean aphids exceeded economic thresholds in all three years, and insecticides successfully suppressed these, outbreaks in the two chemical treatments; aphids exceeded the economic injury level in the cover crop treatment in two of three study years. Bean leaf beetle (Cerotoma trifurcata Forster; Coleoptera: Chrysomelidae) populations were sub-economic in all treatments; insecticides targeting soybean aphid also reduced bean leaf beetles in the first year of study when beetle populations were at their highest. Foliar-dwelling predator populations were substantially higher in the cover crop treatment than in the chemical treatments in all years of study; population declines in the latter treatments were strongly associated with insecticide applications targeting soybean aphids. Foliar predator populations did not rebound within the growing season after insecticides were applied. Soil predator populations were largely unaffected by treatment (except in 2006, when they were more abundant in the cover crop treatment than in the chemical treatments). Weed communities varied among treatments and study years, with few consistent trends except that the chemically intensive treatment had lower weed densities than the other treatments. Although input costs of the cover crop and reduced chemical treatments were lower than the chemically intensive treatment, the chemically intensive treatment was the most profitable of the three. Nevertheless, we contend that the cover crops can be managed more efficiently in order to increase the profitability and competitiveness of this treatment while gaining the long-term benefits gleaned from conserving biodiversity in our agroecosystems.

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

Morphological and molecular studies of six Evlachovaea-like isolates baited from Central Brazilian soils using Triatoma infestans (a vector of Chagas disease) and of other entomopathogens with Evlachovaea-like conidiogenesis led to a re-evaluation of the status of this little known fungal genus. The Brazilian isolates formed two distinct groups based on gene sequences for both the internal transcribed spacer (ITS) and translation elongation factor (EF-1 alpha) genes, morphology, and growth patterns; both groups also differed from the type species, Evlachovaea kintrischica. More detailed studies of these fungi indicated that the altematingly oblique orientations of forming conidia are neither a stable nor invariant character (even on single phialides). Furthermore, the molecular cladistic analysis unambiguously placed the Eulachovaea isolates firmly within the genus Isaria (Hypocreales: Cordycipitaceae). The ITS sequences of E. kintrischica were very similar or even identical to those of Isaria amoenerosea and Isaria cateniobliqua, thereby suggesting that E. kintrischica is a synonym of one of these species, and that the genus Eulachovaea must be treated as a later synonym of Isaria, which must now be recognized to include several highly divergent modes of conidiogenesis. These taxonomic findings are discussed in the context of dramatic changes recently imposed on the nomen-clatural standards used to determine the correct names of all pleomorphic fungi.

The sperm whale (Physeter macrocephalus) is an exception, showing low CR diversity relative to other cetaceans; however, diversity levels throughout the remainder of the sperm whale mitogenome are unknown. We sequenced 20 mitogenomes from 17 sperm whales representative of worldwide diversity using Next Generation Sequencing (NGS) technologies (Illumina GAIIx, Roche 454 GS Junior). Resequencing of three individuals with both NGS platforms and partial Sanger sequencing showed low discrepancy rates (454-Illumina: 0.0071%; Sanger-Illumina: 0.0034%; and Sanger-454: 0.0023%) confirming suitability of both NGS platforms for investigating low mitogenomic diversity. Using the 17 sperm whale mitogenomes in a phylogenetic reconstruction with 41 other species, including 11 new dolphin mitogenomes, we tested two hypotheses for the low CR diversity. First, the hypothesis that CR-specific constraints have reduced diversity solely in the CR was rejected as diversity was low throughout the mitogenome, not just in the CR (overall diversity pi = 0.096%; protein-coding 3rd codon = 0.22%; CR = 0.35%), and CR phylogenetic signal was congruent with protein-coding regions. Second, the hypothesis that slow substitution rates reduced diversity throughout the sperm whale mitogenome was rejected as sperm whales had significantly higher rates of CR evolution and no evidence of slow coding region evolution relative to other cetaceans. The estimated time to most recent common ancestor for sperm whale mitogenomes was 72,800 to 137,400 years ago (95% highest probability density interval), consistent with previous hypotheses of a bottleneck or selective sweep as likely causes of low mitogenome diversity.

Accurate gridded solar radiation data at high spatial and temporal resolution are needed to retrieve ET over large domains. In this work we present an evaluation at hourly, daily and monthly time steps and regional scale (Catalonia, NE Iberian Peninsula) of a satellite-based solar radiation product developed by the Land Surface Analysis Satellite Application Facility (LSA SAF) using data from the Meteosat Second Generation (MSG) Spinning Enhanced Visible and Infrared Imager (SEVIRI). Product performance and accuracy were evaluated for datasets segmented into two terrain classes (flat and hilly areas) and two atmospheric conditions (clear and cloudy sky), as well as for the full dataset as a whole. Evaluation against measurements made with ground-based pyranometers yielded good results in flat areas with an averaged model RMSE of 65 W m(-2) (19%), 34 W m(-2) (9.7%) and 21 W m(-2) (5.6%), for hourly, daily and monthly-averaged solar radiation and including clear and cloudy sky conditions and snow or ice cover. Hilly areas yielded intermediate results with an averaged model RMSE (root mean square error) of 89 W m(-2) (27%), 48 W m(-2) (14.5%) and 32 W m(-2) (9.3%), for hourly, daily and monthly time steps, suggesting the need of further improvements (e.g., terrain corrections) required for retrieving localized variability in solar radiation in these areas. According to the literature, the LSA SAF solar radiation product appears to have sufficient accuracy to serve as a useful and operative input to evaporative flux retrieval models.

These models are typically applied over a range of scales, from headwater streams to higher order rivers, and for a variety of purposes, such as evaluating changes to aquatic habitat or reservoir operation. Most hydrologic models require streamflow data to calibrate subsurface drainage parameters. In many cases, long-term gage records may not be available for calibration, particularly when assessments are focused on low-order stream reaches. Consequently, hydrologic modeling of climate change impacts is often performed in the absence of sufficient data to fully parameterize these hydrologic models. In this paper, we assess a geologic-based strategy for assigning drainage parameters. We examine the performance of this modeling strategy for the McKenzie River watershed in the US Oregon Cascades, a region where previous work has demonstrated sharp contrasts in hydrology based primarily on geological differences between the High and Western Cascades. Based on calibration and verification using existing streamflow data, we demonstrate that: (1) a set of streams ranging from 1st to 3rd order within the Western Cascade geologic region can share the same drainage parameter set, while (2) streams from the High Cascade geologic region require a different parameter set. Further, we show that a watershed comprised of a mixture of High and Western Cascade geologies can be modeled without additional calibration by transferring parameters from these distinctive High and Western Cascade end-member parameter sets. More generally, we show that by defining a set of end-member parameters that reflect different geologic classes, we can more efficiently apply a hydrologic model over a geologically complex landscape and resolve geo-climatic differences in how different watersheds are likely to respond to simple warming scenarios.

Herein, we elaborate upon a novel boosting approach that utilizes synthetic peptides and Toll-like receptor (TLR) agonists as adjuvants to generate sufficient numbers of memory CTLs to protect against infection in mice. Peptide boosting with lipopolysaccharide (LPS), a TLR4-ligand, has been shown to progressively enhance memory CTLs. Whether this result is strictly dependent on activation of TLR4 or can be similarly achieved by signaling through other TLRs is of practical interest in vaccine development but is yet unknown. In this report, we present evidence that intravenous peptide boosting together with TLR3 and TLR9 agonists (Poly IC and CpG, respectively) is highly effective and induces large quantities of memory CTLs of effector memory phenotype after three boosts. Compared to LPS, CpG and Poly IC generate more robust immune responses after the first and second boosts, indicating that a protective level of CTLs might be achieved with fewer boosts when CpG or Poly IC is used. Lastly, the resultant memory CTLs from boosting with different TLR agonists as adjuvant are equally protective against pathogen challenge and are not immune senescent. Therefore, TLR agonists are effective adjuvants in intravenous peptide boosting for the generation of functional memory CTLs. (C) 2012 Elsevier B.V. All rights reserved.

TI Three California annual forbs show little response to neighbor removal SO JOURNAL OF ARID ENVIRONMENTS LA English DT Article DE Facilitation; Grassland; Interference competition; Resource competition ID LIFE-HISTORY; COMPETITION; RESTORATION; PLANTS; SIZE; FACILITATION; GRASSLAND; GROWTH AB In semi-arid systems, competition among plants has limited effects on performance compared to facilitative interactions and abiotic factors. However, the balance between competition and facilitation can change over the course of plant development. Determining when each interaction is important for plant productivity allows us to identify factors limiting plant growth. In this field study, neighbor removal midway through the growing season did not result in a size change for any species (Clarkia purpurea, Plantago erecta, and Micro pus californicus) in the first year. In the second year, two species had greater biomass when neighbors were removed very early in the growing season, indicating a competitive effect. The third species neither benefited nor suffered from neighbor removal. In some years, P. erecta and M. californicus may be negatively affected by competition at early growth stages and are later unable to capitalize on newly-available resources after removals of competitors. This study shows that early-stage competition can drive biomass production in some annual plants, even in semi-arid systems. Published by Elsevier Ltd.

Potential net N mineralization was assayed using laboratory incubations. Results partially supported our hypothesis that herbivory would result in stimulated net N mineralization rates after one year of herbivory exposure, and did not support our hypothesis that herbivory would result in a sustained increase in rates after several years of exposure. Short-term effects differed by site, likely influenced by differences in prevailing soil N status, with net mineralization stimulated at a low fertility site but not at a high fertility site. In the longer-term, there was no impact on overall net N mineralization rates, even though there was a trend towards greater N immobilization in mineral soil. This may result from declining organic matter inputs to soil due to progressive growth limitations from herbivore-induced stress. Results suggest soil N availability will increase in the short-term and eventually decrease in the longer-term at low fertility sites, while soil N availability will not be impacted by herbivory at high fertility sites. Widespread management implications will require further research at sites spanning a range of edaphic characteristics. Published by Elsevier C1 [Uselman, S. M.; Snyder, K. A.; Blank, R.

Six species of phytophagous stink bugs, Nezara viridula (L.), Euschistus servus (Say), Thyanta custator custator (F.), Euschistus quadrator Rolston, Oebalus pugnax pugnax (F.), and Chinavia hilaris (Say), and one predatory species, Podisus maculiventris (Say), occurred in alfalfa. Generally, density of N. viridula, the predominant stink bug species, was high in seeding alfalfa in the late spring-early summer, and parasitization of this stink bug by Trichopoda pennipes (E) could reach high levels as density of the pest increased in the crop. Euschistus servus and T c. custator together comprised the second most predominant group of stink bugs in this crop. Based on seasonal occurrence of nymphs (all 5 instars) and adults, nymphal development time, ovarian development time, and reproductive status of adults (N. viridula only), alfalfa is a reproductive host for N. viridula and E. servus, and perhaps for T c. custator. Mainly adults of E. quadrator, O. p. pugnax, and C. hilaris were present in the crop. Stink bug predators included Geocoris spp., Onus insidiosus (Say), spiders, lady beetles, nabids, reduviids, and Solenopsis invicta Buren.

Moench spp. bicolor] in Georgia. Nezara viridula (L.) was the predominant species in sorghum; density of this stink bug was twice as high as that of the second most abundant stink bug, Oebalus pugnax pugnax (F.). Euschistus servus (Say) was the third most abundant stink bug species. Density of both Leptoglossus phyllopus (L.) and Euschistus quadrator (Rolston) was about half that of E. servus. Chinavia hilaris (Say), Thyanta custator custator (F.), Euschistus tristigmus (Say), Euschistus ictericus (L.), and Piezodorus guildinii (Westwood) were minor pests in sorghum. Adult bugs primarily fed on developing seed. For all bug species, except E. tristigmus and E. ictericus, sorghum served as a reproductive host plant. In order of descending overall abundance, bug predators present in sorghum were Onus insidiosus (Say), Geocoris spp. [Geocoris punctipes (Say) and G. uliginosus (Say)], lady beetle species, i.e., Hippodamia convergens Guerin-Meneville, Coccinella septempunctata (L.), Coleomegilla maculata (De Geer), and Harmonia axyridis (Pallas), spiders, i.e., Peucetia viridans (Hentz), Oxyopes salticus Hentz, and spiders in the Salticidae and Thomisidae families, Solenopsis invicta Buren, Podisus maculiventris (Say), Sinea diadema (F.), and Nabis spp. Conserving these natural enemies of panicle-feeding bugs in sorghum could possibly be used in management of these bugs in southeastern farmscapes.

In an experiment performed inside glass flasks, pupal mortality caused by all fumigants 7 d after a 4-h exposure was significantly higher than in the control, but effects of the five fumigants on pupal mortality 7 d post exposure did not differ consistently even though chloropicrin caused the highest absolute mortality. In contrast, fumigant effects on adult emergence were consistent and clearer in that chloropicrin, Telone II, and chloropicrin + Telone II prevented all emergence of adult flies over 111 - 112 d whereas methyl bromide, ECO2FUME, and Vapam reduced it by only 41 - 73% compared with controls. The differences in pupal mortality and adult emergence patterns suggest that the fumigants acted slowly. This is the first study that shows chloropicrin, Telone II, and the two in combination could be alternative fumigants to methyl bromide for killing pupae and preventing emergence of R. pomonella.

Results demonstrate that, on average, households in the Western United States are willing to pay $154 to improve the resiliency of these forests. Factor analysis shows that long-run protection of the forests dominates recreation in motivating support. Cluster analysis suggests three groups of survey respondents: those indifferent to the program and not willing to pay, those wanting to protect the future of the high-elevation forests, and those wanting to protect both the forests and related recreational opportunities.

Fefids are the only known host that can shed T. gondii oocysts, which are essential to the perpetuation of the parasite. In much of boreal Canada, the Canadian lynx (Lynx canadensis) is the only wild felid host that could contribute to environmental contamination with T. gondii oocysts. We estimated the prevalence of T. gondii antibodies in Canadian lynx from western Quebec and compared our results with earlier findings in the same region 12 yr earlier. We investigated factors associated with seroconversion, including age, sex, geographic location, and possible co-occurrence with domestic cats (Felis catus), and we assessed the proportion of lynx shedding T. gondii oocysts. Blood and fecal samples were collected from 84 lynx harvested by trappers in the eastern part of the study area during winter 2009-2010. Sera were tested for antibodies to T. gondii by the modified agglutination test (cutoff titer 1:50) and fecal samples for parasite eggs by fecal flotation. Antibodies to T. gondii were detected in sera of 14% of 84 lynx. Numerous helminth ova and coccidian oocysts were found in feces, whereas T. gondii like oocysts were not detected. Antibody prevalence increased with age class (odds ratio [OR]=4.33, 95% confidence interval [CI]=1.57-11.99, P<0.01). Antibody prevalence (14%) in our study was significantly lower than in 84 lynx (36%) trapped in the western part of the study area during winter 1997-1998 (OR=0.18, 95% CI=0.08-0.44, P<0.001). Our results suggest there may be significant spatiotemporal dynamics of T. gondii infection in lynx in Canada, and we review possible abiotic and biotic ecologic factors supporting these findings.

TI Oral Rabies Vaccination in Raccoons: Comparison of ONRAB (R) and RABORAL V-RG (R) Vaccine-Bait Field Performance in Quebec, Canada and Vermont, USA SO JOURNAL OF WILDLIFE DISEASES LA English DT Article DE Antibody prevalence; oral rabies vaccination; Procyon lotor; raccoon; striped skunk; vaccine-bait AB The control of rabies in raccoons (Procyon lotor) and striped skunks (Mephitis mephitis) in North America has been conducted mainly through aerial distribution of oral vaccine-baits. The effectiveness of the vaccine-bait used is therefore of prime importance for disease eradication. In a previous field comparison between the ONRAB (R) bait in the province of New Brunswick, Canada, and RABORAL V-RG (R) bait in the state of Maine, USA, the ONRAB bait produced a higher percentage of antibody-positive raccoons under nearly identical bait distribution for the two vaccines. The main objective of the present study was to conduct a similar cross-border comparison of these two vaccine-baits using raccoon sera collected during post oral rabies vaccination monitoring in Quebec, Canada, and Vermont, USA, where ONRAB and V-RG, respectively, were distributed aerially at a targeted density of 150 baits/km(2). A comparison of the equivalency of two serologic tests used in Canada and the USA was also conducted using sera from raccoons and striped skunks. Rabies virus neutralization assay (USA) yielded similar results to the competitive enzyme-linked immunosorbent assay (Canada), with agreement between the two tests of 92% for raccoon sera and 96% for skunk sera. With both assays, the percentage of antibody-positive raccoons was greater with ONRAB (51%, n=265) than with V-RG (38%, n=66). These new results support the conclusion from the previous study, that ONRAB vaccine-baits may be more effective for the control of rabies in raccoons.

Gregory TI Governing metropolitan green infrastructure in the United States SO LANDSCAPE AND URBAN PLANNING LA English DT Article DE Ecosystem services; Green infrastructure; Governance; Institutionalization; Sustainability; Urban forestry ID ENVIRONMENTAL GOVERNANCE; CITIES; PARTICIPATION; POLICY AB In this paper we explore whether the enhancement of urban ecosystem services through large-scale, metropolitan tree-planting initiatives is being planned and executed as a component of traditional municipal government or represents new, transdisciplinary strategies in environmental governance. Drawing on qualitative interviews with stakeholders in six major cities (n = 58) we further explore institutionalization of these initiatives and relationships. While much current discourse posits government cannot "go it alone" in providing preventative, "front-end" solutions to complex environmental problems, we found the public sector dominant in the visioning, planning, and management of these green infrastructure initiatives and the role of the private sector to be minimal. We also found that, despite this dominance, the initiatives had limited success in becoming institutionalized. This dichotomy reflects that while discourses labeling the public sector unable to grapple with complex environmental issues and the private sector dominant in environmental governance regimes are premature, institutionalizing the solutions into the machinery of government remains a contested arena.

In this paper, we integrate the research on environmental stewardship with the social-ecological systems literature to explain how stewardship groups serve as bridge organizations between public agencies and civic organizations, working across scales and sectors to build the flexible and multi-scaled capacity needed to manage complex urban ecosystems. Analyzing data collected from a survey of stewardship groups in New York City, combined with open-ended semi-structured interviews with representatives from the most connected civic "hub" organizations, we use a mixed-method approach to understand the specific activities of bridge organizations in the process of preserving local ecosystem services. This paper concludes that the role of bridge organizations in the management of urban ecosystem services in New York City is increasing, that these groups have a specific bi-modal role in the network, and that an initial presence of heterarchic organizational relations was crucial in their development.

The increased relative humidity levels within riparian areas are essential for many plant and wildlife species. Information about relative humidity patterns within riparian areas and adjacent uplands are necessary for the prescription of effective buffer widths. Relative humidity monitoring is more expensive than temperature monitoring due to greater sensor costs, and it is primarily conducted for research purposes. To make relative humidity monitoring in riparian areas more cost effective, we explored modeling relative humidity as a function of air temperature and other covariates using linear fixed and linear mixed effects models applied to two case studies. Localizing predictions for stream reaches using a linear mixed effects model or a linear fixed effects model with correction factor improved model predictions, especially when large variability among stream reaches was present. A minimum of three to five relative humidity measurements per stream reach seem sufficient to estimate the random stream reach effect or correction factor for the linear mixed and linear fixed effects models, respectively. Including covariates that describe distance to stream and canopy cover in addition to air temperature improved model performance. Although further model refinement is probably needed to allow detection of small changes in relative humidity associated with changes in stand structure from partial overstory removal, the models developed provide a means towards decreasing the costs of monitoring microclimates of importance to riparian area function.

In this paper we explore the linkages among past climate, vegetation, and fire regimes using a high-resolution pollen and charcoal reconstruction from Morris Pond located on the Markagunt Plateau in southwestern Utah, USA. A regime shift detection algorithm was applied to background charcoal accumulation to define where statistically significant shifts in fire regimes occurred. The early Holocene was characterized by greater amounts of summer precipitation and less winter precipitation than modern. Ample forest fuel and warm summer temperatures allowed for large fires to occur. The middle Holocene was a transitional period between vegetation conditions and fire disturbance. The late Holocene climate is characterized as cool and wet reflecting an increase in snow cover, which reduced opportunities for fire despite increased availability of fuels. Similarities between modern forest fuel availability and those of the early Holocene suggest that warmer summers projected for the 21st century may yield substantial increases in the recurrence and ecological impacts of fire when compared to the fire regime of the last millennium.

It is both a serious threat to several U.S. cropping systems and a fascinating model weed. In this paper, we review the growing body of literature on Palmer amaranth to summarize the current state of knowledge on the biology, agricultural impacts, and management of this weed, and we suggest future directions for research.

TI Influence of Palmer Amaranth (Amaranthus palmeri) on the Critical Period for Weed Control in Plasticulture-Grown Tomato SO WEED TECHNOLOGY LA English DT Article DE Interspecific competition; intraspecific competition; light; marketable yields; weed-free period ID COMPETITION; INTERFERENCE AB Field studies were conducted in 1996, 1997, and 1998 at Clinton, NC, to determine the influence of Palmer amaranth establishment and removal periods on the yield and quality of plasticulture-grown 'Mountain Spring' fresh market tomato. Treatments consisted of 14 Palmer amaranth establishment and removal periods. Half of the treatments were weed removal treatments (REM), in which Palmer amaranth was sowed at the time tomato transplanting and allowed to remain in the field for 0 (weed-free all season), 2, 3, 4, 6, 8, or 10 wk after transplanting (WAT). The second set of the treatments, weed establishment treatments (EST), consisted of sowing Palmer amaranth 0 (weedy all season), 2, 3, 4, 6, 8, or 10 WAT and allowing it to grow in competition with tomato the remainder of the season. Tomato shoot dry weight was reduced 23, 7, and 11 g plant(-1) for each week Palmer amaranth removal was delayed from 0 to 10 WAT in 1996, 1997, and 1998, respectively. Marketable tomato yield ranged from 87,000 to 41,000 kg ha(-1) for REM of 0 to 10 WAT and 28,000 to 88,000 kg ha(-1) for EST of 0 to 6 WAT. Percentage of jumbo, large, medium, and cull tomato yields ranged from 49 to 33%, 22 to 31%, 2 to 6%, and 9 to 11%, respectively, for REM of 0 to 10 WAT and 30 to 49%, 38 to 22%, 3 to 2%, and 12 to 9 %, respectively, for EST of 0 to 6 WAT. To avoid losses of marketable tomato yield and percentage of jumbo tomato fruit yield, tomato plots must remain free of Palmer amaranth between 3 and 6 WAT. Observed reduction in marketable tomato yield was likely due to competition for light as Palmer amaranth plants exceeded the tomato plant canopy 6 WAT and remained taller than tomato plants for the remainder of the growing season.

TI Shrub Control in Conservation Reserve Program Lands in Interior Alaska SO WEED TECHNOLOGY LA English DT Article DE Brush control; Conservation Reserve Program; Diamond Wet Blade mower; herbicide ID APPLICATION PLACEMENT EQUIPMENT; SUPPRESSION; EFFICACY AB In Alaska Conservation Reserve Program (CRP) lands, succession of fields planted with grass and clover to shrubs and small trees is resulting in program compliance problems related to ease of reconversion to crop lands. Standard practice for slowing this succession is mowing every 2 to 3 yr, which does not kill the woody vegetation. A field study was conducted at three sites over 2 yr to determine if 2,4-D (2.2 kg ae ha(-1) 2-ethylhexyl ester) or triclopyr (2.2 kg ae ha(-1) butoxyethyl ester) applied broadcast or 2,4-D (2.2 kg ae ha(-1) 2,4-D dimethylamine salt) or triclopyr (1.7 kg ae ha(-1) triclopyr triethylamine salt) applied with a Diamond Wet Blade (TM) mower (DWB) would result in longer shrub control compared to mowing. Mowing was conducted at both 15 and 45 cm above ground level and herbicides were applied with the DWB at three rates. Measurements 2 yr after treatment (YAT) confirmed that both herbicides reduced shrub cover about 50 % compared to controls. Reduced rates of the herbicides applied with the DWB did not result in decreased shrub control. Grass cover was negatively correlated with shrub cover. Typically, mower height did not alter treatment effects. Treatments had little impact on forb cover and composition 2 YAT, with the exception of fireweed, which was generally reduced where herbicides were applied. Application of 2,4-D and triclopyr does not decrease the frequency of shrub control in CRP lands in Alaska. Use of 2,4-D and triclopyr with or without mowing resulted in no widespread improvement over the current practice of mowing to 15 cm every 2 to 3 yr.

This system is based on the use of cereal rye cover crops that are mechanically terminated with a roller-crimper to create in situ mulch that suppresses weeds and promotes soybean growth. In this paper, we report experiments that were conducted over the past decade in the eastern region of the United States on cover crop-based organic rotational no-till soybean production, and we outline current management strategies and future research needs. Our research has focused on maximizing cereal rye spring ground cover and biomass because of the crucial role this cover crop plays in weed suppression. Soil fertility and cereal rye sowing and termination timing affect biomass production, and these factors can be manipulated to achieve levels greater than 8,000 kg ha(-1), a threshold identified for consistent suppression of annual weeds. Manipulating cereal rye seeding rate and seeding method also influences ground cover and weed suppression. In general, weed suppression is species-specific, with early emerging summer annual weeds (e.g., common ragweed), high weed seed bank densities (e.g. > 10,000 seeds m(-2)), and perennial weeds (e.g., yellow nutsedge) posing the greatest challenges. Due to the challenges with maximizing cereal rye weed suppression potential, we have also found high-residue cultivation to significantly improve weed control. In addition to cover crop and weed management, we have made progress with planting equipment and planting density for establishing soybean into a thick cover crop residue. Our current and future research will focus on integrated multitactic weed management, cultivar selection, insect pest suppression, and nitrogen management as part of a systems approach to advancing this new production system.

Implementation of reduced- or no-till practices offers a number of environmental benefits for agricultural land and maintains adequate yield for current and future production. Concerns over satisfactory pest control options, particularly weed control, have contributed to the slow adoption of conservation practices in many areas. To identify effective alternative weed management options for use in conservation systems, research in the Southeast has continued to evaluate the use of cover crops in conjunction with reduced-tillage practices. A number of cover crop species, including cereal grains, legumes, and Brassicaceae species, that have potential to suppress weeds through direct crop interference or allelopathic potential have been investigated. Many recent research projects in the Midsouth and southeastern United States have assessed the success of cover crops in reduced-tillage row crop settings with promising outcomes in some systems. However, continued research is necessary to identify appropriate cover crop and tillage systems for use in other agricultural settings, such as vegetable crops and organic production systems.

TI Role of gibberellic acid in tomato defence against potato purple top phytoplasma infection SO ANNALS OF APPLIED BIOLOGY LA English DT Article DE Defence response; gibberellins; potato purple top phytoplasma; tomato ID SEQUENCE-VARIABLE MOSAICS; X-DISEASE PHYTOPLASMA; REAL-TIME PCR; YELLOWS PHYTOPLASMA; ARABIDOPSIS SEEDS; PLANT-RESPONSES; RESISTANCE; GENOME; GENES; BENZOTHIADIAZOLE AB Infection of tomato by potato purple top (PPT) phytoplasma causes disruption of gibberellin (GA) homeostasis in the plant host. Such pathologically-induced GA deficiency can be partially reversed by exogenous application of GA. This study was designed to explore the role of GA in tomato defence response against phytoplasmal disease, and to determine whether pretreatment with GA would protect healthy tomato seedlings from subsequent phytoplasmal infection and disease development. Our results revealed that, following exogenous GA application and subsequent PPT phytoplasma graft inoculation, there was an apparently coordinated down-regulation of the gene encoding a key GA signalling component and growth repressor known as DELLA protein (GAI) and up-regulation of genes involved in salicylic acid (SA) synthesis (ICS1), signalling (NIM1) and downstream defence responses (PRP-1). Our results also indicated that differential regulation of the above genes was correlated with an increase in activities of defence-related enzymes -1,3-glucanase and chitinase. The data presented in this communication provide evidence to suggest that GA may act via DELLA and SA signalling pathways to modulate host defence in response to PPT phytoplasma infection. Although the GA pretreatment-induced defence was not sufficient to prevent a systemic infection, it reduced phytoplasma titre and significantly attenuated disease symptoms. While the actual molecular mechanism underlying the GA-induced plant defence remains elusive, findings from the current study open new opportunities for in-depth studies of the functional role of the GA signalling network during defence response against phytoplasmal infection.

TI Genetic diversity in morphological characters and phenolic acids content resulting from an interspecific cross between eggplant, Solanum melongena, and its wild ancestor (S.incanum) SO ANNALS OF APPLIED BIOLOGY LA English DT Article DE Breeding; characterisation; chlorogenic acid; functional quality; interspecific hybridisation; introgression ID CHLOROGENIC ACID; ANTIOXIDANT ACTIVITY; DOMESTICATION TRAITS; NUTRITIONAL QUALITY; SCAVENGING ACTIVITY; CAFFEIC ACID; L. CULTIVARS; FRUIT; CONSERVATION; TOMATO AB Solanum incanum, the wild ancestor of eggplant, Solanum melongena, has been considered as a source of variation for high content of phenolic acid conjugates in breeding programmes aimed at improving the functional quality of eggplant. We have evaluated the morphological and phenolic acids content in an interspecific family including S. incanum (P1), S. melongena (P2), their interspecific hybrid (F1), progeny from the selfing of the F1 (F2) and the backcross of the F1 to P2 (BC1P2). Many morphological differences were found between parents, while the F1 was intermediate for most traits. However, F1 plants were taller and pricklier and presented higher fruit flesh browning than any of the parents. F2 and BC1P2 were morphologically highly variable and the results obtained suggest that a rapid recovery of the characteristic combination of S. melongena traits can be achieved in a few backcross generations. Segregation for prickliness was found to be compatible with simple genetic control, prickliness being dominant over non-prickliness. A total of 16 phenolic acid conjugates were studied, of which chlorogenic acid (5-O-(E)-caffeoylquinic acid) was the most common compound in all samples, averaging 77.8% of all hydroxycinnamic acid derivatives. Contents of total phenolic acid conjugates were much higher in S. incanum than in S. melongena fruit flesh, and no major differences were found in the profile of phenolic acids among parents. The interspecific hybrid (F1) was intermediate between the two parents in phenolic acids content. Non-segregating generations presented considerable variation in phenolic acids content, but the range of variation was wider in segregating F2 and BC1P2 generations. Additive genetic effects were the most important in explaining the results obtained for the phenolic acids content. A number of BC1P2 plants presented a good combination of phenolic acids content and fruit weight or flesh browning. Overall, the results demonstrate that improvement of functional quality in S. melongena can be obtained using S. incanum as a donor of alleles for high phenolic acids content.

Mechanistic and structural investigations of Rca have been hampered by its exceptional thermolability, high degree of size polydispersity and propensity towards subunit aggregation. In this work, we have characterized the thermal stability and self-association behavior of recombinant Rca preparations, and have developed ligand screening methods. Thermal denaturation profiles generated by circular dichroism indicate that creosote and tobacco short-form Rcas are the most stable proteins examined, with an estimated mid-point temperature of 45-47 degrees C for protein denaturation. We demonstrate that ADP provides a higher degree of stabilization than ATP, that magnesium ions have a small stabilizing effect on ATP-bound, but a significant destabilizing effect on ADP-bound Rca, and that phosphate provides weak stabilization of the ADP-bound form of the protein. A dimeric species was identified by size-exclusion chromatography, suggesting that the two-subunit module may comprise the basic building block for larger assemblies. Evidence is provided that chromatographic procedures reflect non-equilibrium multimeric states. Dynamic light scattering experiments performed on nucleotide-bearing Rca support the notion that several larger, highly polydisperse assembly states coexist over a broad concentration range. No significant changes in aggregation are observed upon replacement of ADP with ATP. However, in the absence of nucleotides, the major protein population appears to consist of a monodisperse oligomer smaller than a hexamer. (C) 2012 Elsevier B.V. All rights reserved.

Habitat fragmentation is thought to threaten biodiversity, but the response of pollinators to fragmentation is still poorly understood, and research seldom includes pollinator nesting requirements. 2. We investigated pollinator community composition in a highly fragmented oak-savannah ecosystem in south-western British Columbia, Canada. We sampled pollinators in 19 fragments ranging from 0.3 to 31 ha and surrounded by a variety of land-use types, including forest, low-density suburban, and urban neighbourhoods. Pan-trapping and netting surveys captured 4464 bees, flies, and wasps in 138 species and 48 genera. 3. Contrary to expectations, overall species richness did not increase with fragment size. However, ground-nester abundance (not diversity) and cavity-nester diversity (not abundance) were higher in larger fragments, as expected. Floral richness and abundance did not foster pollinator diversity for either guild. Brood parasite responses were complex: host availability (ground-nesting bees) was generally important, richness and abundance increased in fragments with high surrounding road density, and abundance also increased in fragments with other habitat fragments nearby. 4. Responses of different nesting guilds to fragmentation may be related to their use of the landscape surrounding habitat fragments. Some common cavity nesters can nest in fences and gardens, but urban land use may be less hospitable for ground nesters. Brood parasites apparently respond both to host availability and landscape characteristics associated with movement among fragments. 5. Consideration of nesting requirements of pollinators provided some insight into their response to habitat loss in our analysis and should be considered in future studies of fragmentation impacts on pollinator biodiversity.

Fire has been instrumental in the evolution of large segments of flora and fauna and in preventing fuel accumulations that resulted in extreme fire behaviour and ecosystem degradation. However, wildland fuels have been accumulating over several of the past decades because of suppression-orientated wildland fire policies, silvicultural and grazing practices, invasions of invasive species, increased density and range of flammable indigenous plants, landscape fragmentation, and related natural and anthropogenic causes. The additional fuels have contributed to increased severe fire behaviour, fire intensity, forest mortality, and post-fire soil damage and erosion. The aftermath of severe wildland fires include ecosystems degraded by extreme fire temperatures and duration, reductions in ecosystem function, altered forest structure, altered natural fire regimes, and increased wildfire risk and imminent threats to life and property from uncontrollable fires. We review 10 years of advances in fire science in the eight papers presented in this Special Issue. The studies and reviews are compiled to present the diverse disciplines of fire science that range from the social science of the public's perception of fire to basic research on the theory of fire spread.

Over the past 10 years, the application of risk analysis to wildland fire management has seen steady growth with new risk-based analytical tools that support a wide range of fire and fuels management planning scales from individual incidents to national, strategic interagency programs. After a brief review of the three components of fire risk - likelihood, intensity and effects - this paper reviews recent advances in quantifying and integrating these individual components of fire risk. We also review recent advances in addressing temporal dynamics of fire risk and spatial optimisation of fuels management activities. Risk analysis approaches have become increasingly quantitative and sophisticated but remain quite disparate. We suggest several necessary and fruitful directions for future research and development in wildfire risk analysis.

Prior to 2000 the primary focus of most fire research was on the physical and ecological aspects of fire; social science research was limited to a small number of studies. However, as more people moved into fire-prone areas interest grew in understanding relevant social dynamics. This growing interest was supported by increased funding for fire research overall with the creation of the Joint Fire Science Program in 1998 and the National Fire Plan in 2000. In subsequent years, a significant body of research has developed on the human dimensions of wildland fire covering diverse topics including: attitudes towards pre-fire mitigation, social acceptability of fire and fuels management, community preparedness, public response during fires, citizen-agency communications and post-fire recovery. This paper reports on two aspects of a Joint Fire Science Program project intended to take stock of the key social science lessons provided to date: a basic review of findings in the non-economic fire social science literature and identification of future research needs.

Internationally, many fire models have been developed based on a variety of assumptions and expressions for the fundamental heat transfer and combustion processes. The diversity of these assumptions raises the question as to whether the absence of a sound and coherent fire spread theory is partly responsible. We explore the thesis that, without a common understanding of what processes occur and how they occur, model reliability cannot be confirmed. A theory is defined as a collection of logically connected hypotheses that provide a coherent explanation of some aspect of reality. Models implement theory for a particular purpose, including hypotheses of phenomena and practical uses, such as prediction. We emphasise the need for theory and demonstrate the difference between theory and modelling. Increasingly sophisticated fire management requires modelling capabilities well beyond the fundamental basis of current models. These capabilities can only be met with fundamental fire behaviour research. Furthermore, possibilities as well as limitations for modelling may not be known or knowable without first having the theory. C1 [Finney, Mark A.; Cohen, Jack D.; McAllister, Sara S.; Jolly, W.

Processes causing direct effects and indirect, long-term ecosystem changes are complex and multidimensional. Robust risk-assessment tools are required that account for highly variable effects on multiple values-at-risk and balance competing objectives, to support decision making. Providing wildland fire managers with risk-analysis tools requires a broad scientific foundation in fire behaviour and effects prediction as well as high quality computer-based tools and associated databases. We outline a wildfire risk-assessment approach, highlight recent developments in fire effects science and associated research needs, and recommend developing a comprehensive plan for integrated advances in wildfire occurrence, behaviour and effects research leading to improved decision support tools for wildland fire managers. We find that the current state of development in fire behaviour and effects science imposes severe limits on the development of risk-assessment technology. In turn, the development of technology has been largely disconnected from the research enterprise, resulting in a confusing array of ad hoc tools that only partially meet decision-support needs for fuel and fire management. We make the case for defining a common risk-based analytic framework for fire-effects assessment across the range of fire-management activities and developing a research function to support the framework.

This complexity makes it difficult to accurately describe, classify, sample and map fuels for wildland fire research and management. As a result, many fire behaviour and effects software prediction systems use a generalised description of fuels to simplify data collection and entry into various computer programs. There are several major fuel description systems currently used in the United States, Canada and Australia, and this is a source of confusion for many in fire management. This paper (1) summarises the challenges of describing fuels, (2) contrasts approaches (association, classification and abstraction) for developing fuel description systems and (3) discusses possible future directions in wildland fuel description and science to transition to a universal fuel description system. Most discussion centres on surface fuel loadings as the primary descriptive characteristic. This synthesis paper is intended to provide background for understanding surface fuel classification and description systems and their use in simulating fire behaviour and effects, quantifying carbon inventories and evaluating site productivity.

Each site was a replicated experiment with a common design that compared an un-manipulated control, prescribed fire, mechanical and mechanical + fire treatments. Variables within the vegetation, fuelbed, forest floor and soil, bark beetles, tree diseases and wildlife were measured in 10-ha stands, and ecological response was compared among treatments at the site level, and across sites, to better understand the influence of differential site conditions. For most sites, treated stands were predicted to be more resilient to wildfire if it occurred shortly after treatment, but for most ecological variables, short-term response to treatments was subtle and transient. Strong site-specificity was observed in the response of most ecosystem variables, suggesting that practitioners employ adaptive management at the local scale. Because ecosystem components were tightly linked, adaptive management would need to include monitoring of a carefully chosen set of key variables. Mechanical treatments did not serve as surrogates for fire for most variables, suggesting that fire be maintained whenever possible. Restoration to pre-settlement conditions will require repeated treatments over time, with eastern forests requiring more frequent applications.

These vary in severity from hazardous (acute health conditions and drastic visibility impairment to transportation) to nuisance (regional haze), and occur across a range of scales (local to continental). Over the years a variety of tools have been developed to aid in predicting smoke effects. This review follows the development of these tools, from various indices and simple screening models to complex air quality modelling systems, with a focus on how each tool represents key processes involved in smoke transport.

Using this new knowledge, we have developed several tools to assist land managers with post-wildfire assessment and treatment decisions, such as prediction models, research syntheses, equipment and methods for field measurements, reference catalogues and databases of past-practice, and spreadsheets for calculating resource valuation and cost-benefit analysis. These tools provide relevant science to post-fire assessment teams and land managers in formats that often can be directly entered into assessment and treatment decision-making protocols. Providing public access to these tools through the internet not only has increased their dissemination, but also has allowed them to be updated and improved as new knowledge and technology become available. The use of these science-based tools has facilitated a broader application of current knowledge to post-fire management in the United States and in other fire-prone areas around the world.

Growth chamber studies (E1 and E2) that used three P and two CO2 levels were conducted. Leaf, stem, tuber, and stolon dry matter increased with P. Lateral-stem production was sensitive to P with a minimum 2.5-fold increase in mass. Leaf length increased an average 20.2% in E1 and 38.2% in E2 and leaf area increased an average 336% in E1 and 470% in E2 across CO2 levels. Tuber dry mass increased 22% in E1 and 38.2% in E2 in response to elevated CO2 and total dry mass by 14.1 and 15.4%. Tissue P contents increased with P but were unaffected by CO2. Effects of P on canopy branching were associated with plant N status. The studies suggest elevated CO2 levels are unlikely to alter potato P requirements on a unit mass basis. C1 [Fleisher, D.

However, yogurt, a nutrient-dense milk product, has been understudied. This cross-sectional study examined whether yogurt consumption was associated with better diet quality and metabolic profile among adults (n = 6526) participating in the Framingham Heart Study Offspring (1998-2001) and Third Generation (2002-2005) cohorts. A validated food frequency questionnaire was used to assess dietary intake, and the Dietary Guidelines Adherence Index (DGAI) was used to measure overall diet quality. Standardized clinical examinations and laboratory tests were conducted. Generalized estimating equations examined the associations of yogurt consumption with diet quality and levels of metabolic factors. Approximately 64% of women (vs 41% of men) were yogurt consumers (ie, consumed >0 servings/week). Yogurt consumers had a higher DGAI score (ie, better diet quality) than nonconsumers. Adjusted for demographic and lifestyle factors and DGAI, yogurt consumers, compared with nonconsumers, had higher potassium intakes (difference, 0.12 g/d) and were 47%, 55%, 48%, 38%, and 34% less likely to have inadequate intakes (based on Dietary Reference Intake) of vitamins B2 and B12, calcium, magnesium, and zinc, respectively (all P <= .001). In addition, yogurt consumption was associated with lower levels of circulating triglycerides, glucose, and lower systolic blood pressure and insulin resistance (all P < .05). Yogurt is a good source of several micronutrients and may help to improve diet quality and maintain metabolic well-being as part of a healthy, energy-balanced dietary pattern. (C) 2013 Elsevier Inc.

Objectives: We assessed if pretreatment of primary hippocampal neurons with walnut extract or PUFAs would protect cells against dopamine- and lipopolysaccharide-mediated cell death and calcium dysregulation. Methods: Rat primary hippocampal neurons were pretreated with varying concentrations of walnut extract, linoleic acid, alpha-linolenic acid, eicosapentaenoic acid, or docosahexaenoic acid prior to exposure to either dopamine or lipopolysaccharide. Viability was assessed using the Live/Dead Cellular Viability/Cytotoxicity Kit. Also, the ability of the cells to return to baseline calcium levels after depolarization was measured with fluorescent imaging. Results: Results indicated that walnut extract, alpha-linolenic acid, and docosahexaenoic acid provided significant protection against cell death and calcium dysregulation; the effects were pretreatment concentration dependent and stressor dependent. Linoleic acid and eicosapentaenoic acid were not as effective at protecting hippocampal cells from these insults. Discussion: Walnut extract and omega-3 fatty acids may protect against age-related cellular dysfunction, but not all PUFAs are equivalent in their beneficial effects.

Retina (4 mm macular punch, 4-8 mm annulus, and periphery) and brain tissue (cerebellum, frontal cortex, occipital cortex, and pons) from the same animals were analyzed by reverse-phase high-performance liquid chromatography. Results: Lutein in the macula and annulus was significantly related to lutein levels in the cerebellum, occipital cortex, and pons, both in bivariate analysis and after adjusting for age, sex and n-3 fatty acid status. In the frontal cortex the relationship was marginally significant. Macular zeaxanthin was significantly related to zeaxanthin in the cerebellum and frontal cortex, while the relationship was marginally significant in the occipital cortex and pons in a bivariate model. Discussion: An integrated measure of total macular pigment optical density, which can be measured non-invasively, has the potential to be used as a biomarker to assess brain lutein and zeaxanthin status.

Adult plant resistance to stripe rust resistance in wheat is often durable. To gain a better understanding of the mechanism of adult plant resistance, a suppressive subtractive hybridization (SSH) approach was used to identify wheat genes induced by Pst infection at the adult plant stage. Based on the putative functions of 436 SSH-derived unigene sequences, we characterized defense responses triggered during infection and development of adult plant resistance in wheat cultivar Xingzi 9104. Eighty nine genes were found to be involved in defense and signal transduction. Twelve of the genes were selected for time-course expression analyses using quantitative RT-PCR. Nine of those genes were induced by Pst infection, including those predicted to encode peroxidase, BAX inhibitor, Concanavalin A-like lectin/glucanase, subtilisin-chymotrypsin inhibitor, chinase, glucan endo-1,3-beta-D-glucosidase and acidic PR5 precursor. We found that some PR protein genes kept high expression levels longer in the adult plants than in seedlings after Pst infection. This study is the first to report a concanavalin A-like lectin/glucanase involved in plant defense against pathogen infection. The large number of genes obtained through constructing the SSH library are valuable for further studies to achieve a better understanding of molecular mechanisms of stripe rust resistance in wheat and also useful for studying resistance mechanisms in other plant pathosystems.

Pods were malformed 30 days after inoculation (DAI) and sporulation was observed 60 DAI. Glucose and asparagine concentrations decreased and mannitol and malonate increased in infected pods 30 DAI. By 60 DAI, most carbohydrates, amino acids, and organic acids were drastically reduced by infection. Mannitol and succinic acid levels increased 60 DAI and likely originated from Mr. RT-qPCR analysis of cacao ESTs indicated a strong response to infection 30 DAI in malformed pod. Evidence indicated that biotrophic hyphae colonized pods and a shift to necrotrophic growth occurred later (during the end stages of infection). Expression of cacao ESTs associated with plant hormone biosynthesis and action was altered. Changes in the expression of Mr ESTs in response to nutrient deficiency in pure culture were small. Changes in Mr gene expression patterns and levels of specific metabolites in necrotic sporulating pods 60 DAI compared to malformed pods 30 DAI indicated that the glyoxylate cycle of Mr was up regulated during the shift from biotrophic to necrotrophic phases of the disease cycle.

TI Retroactive Maintains Cuticle Integrity by Promoting the Trafficking of Knickkopf into the Procuticle of Tribolium castaneum SO PLOS GENETICS LA English DT Article ID DROSOPHILA-MELANOGASTER; CHITIN SYNTHASES; DIFFERENTIATION; ORGANIZATION; PROTEINS; INSECTS; FAMILY AB Molting, or the replacement of the old exoskeleton with a new cuticle, is a complex developmental process that all insects must undergo to allow unhindered growth and development. Prior to each molt, the developing new cuticle must resist the actions of potent chitinolytic enzymes that degrade the overlying old cuticle. We recently disproved the classical dogma that a physical barrier prevents chitinases from accessing the new cuticle and showed that the chitin-binding protein Knickkopf (Knk) protects the new cuticle from degradation. Here we demonstrate that, in Tribolium castaneum, the protein Retroactive (TcRtv) is an essential mediator of this protective effect of Knk. TcRtv localizes within epidermal cells and specifically confers protection to the new cuticle against chitinases by facilitating the trafficking of TcKnk into the procuticle. Down-regulation of TcRtv resulted in entrapment of TcKnk within the epidermal cells and caused molting defects and lethality in all stages of insect growth, consistent with the loss of TcKnk function. Given the ubiquity of Rtv and Knk orthologs in arthropods, we propose that this mechanism of new cuticle protection is conserved throughout the phylum.

TI Switchgrass Genomic Diversity, Ploidy, and Evolution: Novel Insights from a Network-Based SNP Discovery Protocol SO PLOS GENETICS LA English DT Article ID REDUCED REPRESENTATION LIBRARY; PANICUM-VIRGATUM; POLYMORPHISM DISCOVERY; LINKAGE MAP; MAIZE; SEQUENCE; MODEL; COMPLEXITY; SELECTION; SOFTWARE AB Switchgrass (Panicum virgatum L.) is a perennial grass that has been designated as an herbaceous model biofuel crop for the United States of America. To facilitate accelerated breeding programs of switchgrass, we developed both an association panel and linkage populations for genome-wide association study (GWAS) and genomic selection (GS). All of the 840 individuals were then genotyped using genotyping by sequencing (GBS), generating 350 GB of sequence in total. As a highly heterozygous polyploid (tetraploid and octoploid) species lacking a reference genome, switchgrass is highly intractable with earlier methodologies of single nucleotide polymorphism (SNP) discovery. To access the genetic diversity of species like switchgrass, we developed a SNP discovery pipeline based on a network approach called the Universal Network-Enabled Analysis Kit (UNEAK). Complexities that hinder single nucleotide polymorphism discovery, such as repeats, paralogs, and sequencing errors, are easily resolved with UNEAK. Here, 1.2 million putative SNPs were discovered in a diverse collection of primarily upland, northern-adapted switchgrass populations. Further analysis of this data set revealed the fundamentally diploid nature of tetraploid switchgrass. Taking advantage of the high conservation of genome structure between switchgrass and foxtail millet (Setaria italica (L.) P. Beauv.), two parent-specific, synteny-based, ultra high-density linkage maps containing a total of 88,217 SNPs were constructed. Also, our results showed clear patterns of isolation-by-distance and isolation-by-ploidy in natural populations of switchgrass. Phylogenetic analysis supported a general south-to-north migration path of switchgrass. In addition, this analysis suggested that upland tetraploid arose from upland octoploid. All together, this study provides unparalleled insights into the diversity, genomic complexity, population structure, phylogeny, phylogeography, ploidy, and evolutionary dynamics of switchgrass.

TI A Quartet of PIF bHLH Factors Provides a Transcriptionally Centered Signaling Hub That Regulates Seedling Morphogenesis through Differential Expression-Patterning of Shared Target Genes in Arabidopsis SO PLOS GENETICS LA English DT Article ID PHYTOCHROME-INTERACTING FACTORS; GENOME-WIDE IDENTIFICATION; CHLOROPHYLL BIOSYNTHESIS; CHLOROPLAST DEVELOPMENT; NEGATIVE REGULATOR; SHADE AVOIDANCE; FAMILY-MEMBERS; CHIP-CHIP; LIGHT; NETWORK AB Dark-grown seedlings exhibit skotomorphogenic development. Genetic and molecular evidence indicates that a quartet of Arabidopsis Phytochrome (phy)-Interacting bHLH Factors (PIF1, 3, 4, and 5) are critically necessary to maintaining this developmental state and that light activation of phy induces a switch to photomorphogenic development by inducing rapid degradation of the PIFs. Here, using integrated ChIP-seq and RNA-seq analyses, we have identified genes that are direct targets of PIF3 transcriptional regulation, exerted by sequence-specific binding to G-box (CACGTG) or PBE-box (CACATG) motifs in the target promoters genome-wide. In addition, expression analysis of selected genes in this set, in all triple pif-mutant combinations, provides evidence that the PIF quartet members collaborate to generate an expression pattern that is the product of a mosaic of differential transcriptional responsiveness of individual genes to the different PIFs and of differential regulatory activity of individual PIFs toward the different genes. Together with prior evidence that all four PIFs can bind to G-boxes, the data suggest that this collective activity may be exerted via shared occupancy of binding sites in target promoters.

The "Cambrian Explosion" marks the onset of dominant aerobic life. Fossil intracellular structures are so similar to extant organisms that they were likely made with similar membrane lipids and proteins, which together provided for organisation and specialisation. While amino acids could be synthesised over 4 billion years ago, only oxidative metabolism allows for the synthesis of highly unsaturated fatty acids, thus producing novel lipid molecular species for specialised cell membranes. Docosahexaenoic acid (DHA) provided the core for the development of the photoreceptor, and conversion of photons into electricity stimulated the evolution of the nervous system and brain. Since then, DHA has been conserved as the principle acyl component of photoreceptor synaptic and neuronal signalling membranes in the cephalopods, fish, amphibian, reptiles, birds, mammals and humans. This extreme conservation in electrical signalling membranes despite great genomic change suggests it was DHA dictating to DNA rather than the generally accepted other way around. We offer a theoretical explanation based on the quantum mechanical properties of DHA for such extreme conservation. The unique molecular structure of DHA allows for quantum transfer and communication of pi-electrons, which explains the precise depolarisation of retinal membranes and the cohesive, organised neural signalling which characterises higher intelligence.

As a result, surface soil arsenic concentrations average 280 mg kg(-1) across more than 60 km(2) of former sugar plantation land in the eastern portion of the Island of Hawaii. This study was conducted to elucidate the relationship between soil properties and arsenic bioaccessibility in the iron-rich volcanic soils. Soils are predominantly Andisols, formed by weathering of basaltic lava and tephra, with pedogenic solid phases consisting of short-range order iron oxyhydroxides, allophane-like aluminosilicates, and metal-humus compounds. These reactive solid phases strongly adsorb oxyanions, such as phosphate and arsenite/arsenate. High arsenic sorption capacity limits desorption and vertical migration within the soil column and prevents contamination of the underlying groundwater aquifer, despite high arsenic loading and precipitation rates. In vitro arsenic bioaccessibility, as measured by the SBRC gastric-phase test, ranges from 2% to 35% and averages 9% of total arsenic. Bioaccessible arsenic is higher in less weathered soils (Udifolists, Typic and Lithic Hydrudands) and lower in more weathered ash-dominant soils (Acrudoxic Hydrudands). Soil weathering indicators, such as reactive iron content, are strong predictors of arsenic bioaccessibility. Based on evidence from soil mineralogy, geochemistry and arsenic speciation, as well as limited soil arsenic bioavailability/bioaccessibility comparisons, risks to human health from direct contact (soil ingestion) are significantly reduced by low arsenic bioaccessibility. Nonetheless, some soils within former sugar cane cultivation areas contain bioaccessible arsenic concentrations exceeding Hawaii Department of Health risk-based action levels, and will require mitigating actions. Even higher levels of soil arsenic contamination have been identified at former pesticide storage and mixing areas, but are generally of localized extent. (C) 2012 Elsevier B.V. All rights reserved.

TI Downstream approaches to phosphorus management in agricultural landscapes: Regional applicability and use SO SCIENCE OF THE TOTAL ENVIRONMENT LA English DT Review DE Phosphorus; Best management practice; Aquatic system; Agriculture ID GULF-OF-MEXICO; IN-STREAM WETLAND; PALUSTRINE FORESTED WETLANDS; WATER TREATMENT RESIDUALS; 2-STAGE CHANNEL SYSTEMS; APPLIED POULTRY LITTER; FURNACE STEEL SLAG; LOW-GRADE WEIRS; DRAINAGE DITCHES; CONSTRUCTED WETLANDS AB This review provides a critical overview of conservation practices that are aimed at improving water quality by retaining phosphorus (P) downstream of runoff genesis. The review is structured around specific downstream practices that are prevalent in various parts of the United States. Specific practices that we discuss include the use of controlled drainage, chemical treatment of waters and soils, receiving ditch management, and wetlands. The review also focuses on the specific hydrology and biogeochemistry associated with each of those practices. The practices are structured sequentially along flowpaths as you move through the landscape, from the edge-of-field, to adjacent aquatic systems, and ultimately to downstream P retention. Often practices are region specific based on geology, cropping practices, and specific P related problems and thus require a right practice, and right place mentality to management. Each practice has fundamental P transport and retention processes by systems that can be optimized by management with the goal of reducing downstream P loading after P has left agricultural fields. The management of P requires a system-wide assessment of the stability of P in different biogeochemical forms (particulate vs. dissolved, organic vs. inorganic), in different storage pools (soil, sediment, streams etc.), and under varying biogeochemical and hydrological conditions that act to convert P from one form to another and promote its retention in or transport out of different landscape components. There is significant potential of hierarchically placing practices in the agricultural landscape and enhancing the associated P mitigation. But an understanding is needed of short- and long-term P retention mechanisms within a certain practice and incorporating maintenance schedules if necessary to improve P retention times and minimize exceeding retention capacity.

Bioavailability or mobility of inorganic As in soil has been reported to be significantly influenced by soil minerals such as iron (hydr) oxide; however, the interactions of organic As such as monosodium methanearsonate (MSMA) with soil minerals are little studied, thus largely unknown. In an effort to minimize the As uptake by rice and determine rice cultivar response to soil MSMA level, a field experiment was conducted on three rice cultivars grown in both MSMA-treated and -untreated soils under continuous or intermittent flood water management practices. Results indicated that the grain yield and the occurrence of straighthead disease were cultivar-dependent and influenced by soil As level and water management practices. Straighthead-resistant cultivars yielded more and had lower grain As than the susceptible ones. Elevated soil As with continuous flood management significantly reduced the grain yield of susceptible cultivars by >89% due to substantially increased straighthead, which were induced by increased As content in grains. Yield reduction by MSMA treatment could be partially mitigated with intermittent flood water practice. The As accumulation was found to be associated with soil iron redox transformation influenced by the water management. This study demonstrates that the selection of less As-susceptible cultivars and intermittent flood water practice could be effective means to lower the As accumulation in grains and minimize the occurrence of the As-induced straighthead symptom and yield reduction.

Quantitative polymerase chain reaction (qPCR) detects changes in the DNA mass of a target organism and is a potential tool for studying quiescent infections. The aim was to optimise a duplex qPCR to quantify B.?cinerea DNA in the background of endogenous Vitis vinifera DNA. Methods and Results Three DNA extraction techniques and three probe sets were compared. The optimised qPCR using the Bc3 probe set was 1000-fold more sensitive than other probe sets, with a threshold cycle value of <33 for as little as 1 picogram of B.?cinerea DNA. The duplex assay successfully detected an increasing amount of B.?cinerea DNA when mixed with V.?vinifera DNA or of B.?cinerea conidia when added to grape receptacles. Conclusions Duplex assays quantifying B.?cinerea DNA in the background of endogenous grape DNA were efficient and sensitive, with calculation of a pathogen coefficient allowing comparison of results among assays. Significance of the Study The results demonstrate the potential to monitor symptomless, quiescent infections and to investigate the consequence of an intervention (e.g. a fungicide treatment) before disease symptoms are visible.

Clinical symptoms of the disease caused by BVDV range from subclinical to severe acute hemorrhagic syndrome, with the severity of disease being strain dependent. These viruses are classified as members of the Pestivirus genus of the Flaviviridae. BVDV are considered primarily a pathogen of cattle but can infect most ruminant species. The virus particle consists of a lipid bilayer membrane surrounding the encapsidated genomic RNA. Inserted in the outer membrane are two virus-encoded glycoproteins that contain the major antigenic determinants of the virus as well as receptor binding and cell fusion functions. A third glycoprotein is weakly associated with the virion, but also possesses unique features that play important roles in suppression of innate immunity. The viral proteins are encoded in a single, large open reading frame. The viral proteins are proteolytically cleaved from the polyprotein by different proteases. The structural proteins are processed by cellular signal peptidases while the processing of the nonstructural proteins is by the viral serine protease. The virus is assembled and matures in the endoplasmic reticulum and golgi bodies of the cell. The virus is released via exocytosis, where viral proteins are not exposed on the surface of the cell.

Both modified live and killed vaccines have been shown to be efficacious under controlled conditions. Both humoral and cellular immune responses are protective. Following natural infection or vaccination with a modified live vaccine, the majority of the B cell response (as measured by serum antibodies) is directed against the viral proteins E2 and NS2/3, with minor responses against the Ems and E1 proteins. Vaccination with killed vaccines results in serum antibodies directed mainly at the E2 protein. It appears that the major neutralizing epitopes are conformational and are located within the N-terminal half of the E2 protein. While it is thought that the E2 and NS2/3 proteins induce protective T cell responses, these epitopes have not been mapped. Prevention of fetal infections requires T and B cell response levels that approach sterilizing immunity. The heterogeneity that exists among circulating BVDV strains, works against establishing such immunity. Vaccination, while not 100% effective in every individual animal, is effective at the herd level.

The study used a set of spatial pattern metrics derived from multispectral imagery acquired with an MS3100-CIR digital camera. Thematic maps were generated from the subset of multispectral image of each wheat field. A discriminant function analysis was used to determine whether the set of spatial pattern metrics derived from thematic imps could differentiate the categories of stress. The study concluded that it was possible to use class-based spatial pattern metrics to differentiate stress induced by D. noxia from other stress factors. (c) 2012 Elsevier B.V. All rights reserved.

TI Indiana bat summer maternity distribution: effects of current and future climates SO ECOLOGY AND EVOLUTION LA English DT Article DE Climate change; Indiana bats; maternity habitat; Myotis sodalis; species distribution models ID WHITE-NOSE SYNDROME; WESTERN NORTH-AMERICA; MYOTIS-SODALIS; SPECIES DISTRIBUTIONS; CHAMPLAIN VALLEY; RANGE EXPANSION; UNITED-STATES; BIODIVERSITY; LACTATION; MAMMALS AB Temperate zone bats may be more sensitive to climate change than other groups of mammals because many aspects of their ecology are closely linked to temperature. However, few studies have tried to predict the responses of bats to climate change. The Indiana bat (Myotis sodalis) is a federally listed endangered species that is found in the eastern United States. The northerly distribution of Indiana bat summer maternity colonies relative to their winter distributions suggests that warmer climates may result in a shift in their summer distribution. Our objectives were to determine the climatic factors associated with Indiana bat maternity range and forecast changes in the amount and distribution of the range under future climates. We used Maxent to model the suitable climatic habitat of Indiana bats under current conditions and four future climate forecasts for 202130, 203140, 204150, and 205160. Average maximum temperature across the maternity season (MayAugust) was the most important variable in the model of current distribution of Indiana bat maternity colonies with suitability decreasing considerably above 28 degrees C. The areal extent of the summer maternity distribution of Indiana bats was forecasted to decline and be concentrated in the northeastern United States and Appalachian Mountains; the western part of the current maternity range (Missouri, Iowa, Illinois, Kentucky, Indiana, and Ohio) was forecasted to become climatically unsuitable under most future climates. Our models suggest that high temperatures may be a factor in roost-site selection at the regional scale and in the future, may also be an important variable at the microhabitat scale. When behavioral changes fail to mitigate the effects of high temperature, range shifts are likely to occur. Thus, habitat management for Indiana bat maternity colonies in the northeastern United States and Appalachian Mountains of the Southeast is critical as these areas will most likely serve as climatic refugia.

However, many of these systems have not been deployed in this sector and the products they produce from forest biomass have not been adequately described or characterized with regards to chemical properties, possible uses, and markets. This paper characterizes the producer gas, biochar, and activated carbon of a 700 kg h(-1) prototype gasification system and a 225 kg h(-1) pyrolysis system used to process coniferous sawmill and forest residues. Producer gas from sawmill residues processed with the gasifier had higher energy content than gas from forest residues, with averages of 12.4 MJ m(-3) and 9.8 MJ m(-3), respectively. Gases from the pyrolysis system averaged 1.3 MJ m(-3) for mill residues and 2.5 MJ m(-3) for forest residues. Biochars produced have similar particle size distributions and bulk density, but vary in pH and carbon content. Biochars from both systems were successfully activated using steam activation, with resulting BET surface area in the range of commercial activated carbon. Results are discussed in the context of co-locating these systems with forest industry operations. C1 [Anderson, Nathaniel; Jones, J.

TI Juvenile hormone levels reflect social opportunities in the facultatively eusocial sweat bee Megalopta genalis (Hymenoptera: Halictidae) SO HORMONES AND BEHAVIOR LA English DT Article DE Megalopta genalis; Juvenile hormone; Social dominance; Eusociality; Endocrine physiology ID DIVISION-OF-LABOR; POGONOMYRMEX-CALIFORNICUS; ECUADORIA HYMENOPTERA; ENDOCRINE PHYSIOLOGY; OVARIAN DEVELOPMENT; POLISTES-GALLICUS; BOMBUS-TERRESTRIS; WASP; QUEENS; DOMINANCE AB The evolution of eusociality is hypothesized to have involved de-coupling parental care from reproduction mediated by changes in endocrine regulation. While data for obligately eusocial insects are consistent with this hypothesis, we lack information from species representative of the transition from solitary reproduction to eusociality. Here we report the first evidence for a link between endocrine processes and social behavior in a facultatively eusocial bee, Megalopta genalis (Halictidae). Using females that varied in social, reproductive, and ecological context, we measured juvenile hormone (JH), a major regulator of colony caste dynamics in other eusocial species. JH was low at adult emergence, but elevated after 10 days in all nesting females. Females reared in cages with ad lib nutrition, however, did not elevate JH levels after 10 days. All reproductive females had significantly more JH than all age-matched non-reproductive females, suggesting a gonadotropic function. Among females in established nests, RI was higher in queens than workers and solitary reproductives, suggesting a role for JH in social dominance. A lack of significant differences in JH between solitary reproductives and non-reproductive workers suggests that JH content reflects more than reproductive status. Our data support the hypothesis that endocrine modifications are involved in the evolutionary decoupling of reproductive and somatic effort in social insects. These are the first measurements of JH in a solitary-nesting hymenopteran, and the first to compare eusocial and solitary nesting individuals of the same species. Published by Elsevier Inc.

TI Graft Angle and Its Relationship to Tomato Plant Survival SO HORTSCIENCE LA English DT Article DE Solanum lycopersicum; robotics; manual grafting; pull force; rootstocks ID VEGETATIVE COMPATIBILITY-INCOMPATIBILITY AB Growing transplants that can withstand the rigors of open-field production is imperative for the successful adoption of grafting in large-scale commercial fields and especially for those who seek to adopt this technology as an alternative to soil fumigation. This study examines the relationship of tensile strength to graft angle and plant survival. Tomato (Solanum lycopersicum) seedlings of 'FL-47' and 'Rutgers' were used as scions on 'Roma' rootstock under greenhouse and healing chamber conditions. Scions were grafted at angles of 20 degrees, 45 degrees, and 70 degrees. After a period of 10 days, the plants were severed near ground level and subjected to pull force analysis. Pull force of the graft increased significantly with the increased graft angle. Pull force between the 20 degrees vs. 70 degrees angles increased significantly as well as those of 45 degrees vs. 70 degrees grafts (P <= 0.001). Increase in graft angle resulted in greater survival of grafted plants from 79% (20 degrees), 81% (45 degrees), and 92% (70 degrees). Fifteen commercial rootstocks grafted at 70 degrees had survival percentage rates between 97% and 100%. These studies demonstrate that the angle can significantly impact graft integrity and plant survival. C1 ARS, USDA, US Hort Res Lab, Ft Pierce, FL 34945 USA.

TI Serial Transmission of Plant Viruses by Cutting Implements during Grafting SO HORTSCIENCE LA English DT Article DE meristem; axillary buds; plant pathogens; vegetable production ID MOSAIC-VIRUS; INFECTION AB Reciprocal grafts of two tomato (Solanum lycopersicum L.) cultivars were made by hand using commercial grafting techniques. The razor blade used to cut the rootstock or scion was first contaminated by making a single cut on tomato plants infected with either Tomato spotted wilt virus (TSWV) or Tomato mosaic virus (ToMV). Although no transmission of TSWV was observed in these experiments, ToMV was spread plant to plant through razor blade exposure to this virus. The presence of this virus was confirmed by double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) at 21 days post-inoculation. The highest rate of infection was 25% of the inoculated plants. The greatest number of positive virus assays was found in the first 10 plants of each experiment. These areas contained 84% of the DAS-ELISA-positive plants. Gaps of up to 10 plants occurred during serial inoculation before infection resumed. Random dispersion occurred in two experiments. Similar results were observed whether the contaminated implement was used to cut the rootstock or the scion before graft assembly. This work demonstrates that some viruses from a single contamination can be moved in a serial manner during the grafting process, especially with varieties with minimal or no resistance to viral plant pathogens. Also, visual diagnosis cannot always be relied on as a means of eliminating virus-infected plants, especially when higher greenhouse and annealing temperatures are maintained.

TI Evaluating Paradox Walnut Rootstocks for Resistance to Armillaria Root Disease SO HORTSCIENCE LA English DT Article DE Armillaria mellea; black walnut; clonal rootstocks; Juglans regia; Pterocmya stenoptera ID MELLEA; GRAPEVINE AB The most common rootstock for Juglans regia (Persian or "English" walnut) in California is Paradox, typically a hybrid off hindsii (Northern California black walnut) x J. regia. Unfortunately, Paradox is very susceptible to Armillaria root disease. The relative resistance to Armillaria mellea of six clonally propagated Paradox rootstocks (AX1, Px1, RR4 11A, RX1, Vlach, VX211) was evaluated and compared with that of clonally propagated J. hindsii rootstock selection W17, J. regia scion cultivar Chandler, and Pterocarya stenoptera (Chinese wingnut). In a growth-chamber assay, plants were micropropagated and rooted in vitro before inoculating the culture medium with A. mellea. At two months post-inoculation, the most resistant and susceptible Paradox rootstocks were AX1 and VX211, respectively, with 9% vs. 70% mortality, and this finding was consistent across three isolates of A. mellea and three replicate experiments. This broad range of resistance within Paradox is consistent with past field trials that tested other genotypes. Our finding of similarly high susceptibility of 'Chandler' and W17 (61% vs. 69% mortality) is in contrast to two field trials, in which other J. regia genotypes were more susceptible than those off. hindsii. A third trial, however, identified some J. regia genotypes as more resistant than those off. hindsii. Therefore, it is possible that W17, which was not previously tested, is an Armillaria-susceptible genotype of J. hindsii. Based on our findings of repeatable mortality levels across three isolates of A. mellea and three replicate experiments, the growth-chamber assay has promise, albeit with confirmed resistant and susceptible controls, for identifying putative resistant rootstocks (e.g., AX1) in preparation for a field trial with controlled inoculations.

The spectrum of each pixel in a hyperspectral image is considered as a linear combinations of the spectra of the vegetation and the bare soil. Recently developed linear unmixing approaches are evaluated in this paper, which automatically extracts the spectra of the vegetation and bare soil from the images. The vegetation abundances are then computed based on the extracted spectra. In order to reduce the influences of this uncertainty and obtain a robust estimation results, the vegetation abundances extracted on two different dates on the same fields are then combined. The experiments are carried on the multidate hyperspectral images taken from two grain sorghum fields. The results show that the correlation coefficients between the vegetation abundances obtained by unsupervised linear unmixing approaches are as good as the results obtained by supervised methods, where the spectra of the vegetation and bare soil are measured in the laboratory. In addition, the combination of vegetation abundances extracted on different dates can improve the correlations (from 0.6 to 0.7).

More broadly, uncertainty data are placed within the context of conclusive interpretations of comparative bioproduct LCA results. Data from the US Department of Agriculture's Agricultural Resource Management Survey were parameterized for 466 crop-state-year combinations, using 146 variables representing the previous crop, tillage and seed operations, irrigation, and applications of synthetic fertilizer, lime, nitrogen inhibitor, organic fertilizer, and pesticides. Data are described by Student's t distributions representing sampling error through the relative standard error (RSE) and are organized by the magnitude of the RSE by data point. Also, instances in which the bounds of the 95 % confidence intervals are less than zero or exceed actual limits are identified. Although the vast majority of the data have a RSE less than 100 %, values range from 0 to 1,600 %. The least precision was found in data collected between 2001 and 2002, in the production of corn and soybeans and in synthetic and pesticide applications and irrigation data. The highest precision was seen in the production of durum wheat, rice, oats, and peanuts and in data representing previous crops and till and seed technology use. Additionally, upwards of 20 % of the unit process, data had 95 % confidence intervals that are less than or exceed actual limits, such as an estimation of a negative area or a portion exceeding a total area, as a consequence of using a jackknife on subsets of data for which the weights are not calibrated explicitly and a low presence of certain practices. High RSE values arise from the RSE representing a biased distribution, a jackknife estimate being nearly zero, or error propagation using low-precision data. As error propagates to the final unit process data, care is required when interpreting an inventory, e.g., Monte Carlo simulation should only be sampled within the appropriate bounds. At high levels of sampling error such as those described here, comparisons of LCA bioproduct results must be made with caution and must be tested to ensure mean values are different to a desired level of significance.

Simultaneous trapping for multiple species, by baiting traps with several lures, is expected to increase the number of species that can be targeted in surveillance programs and improve the cost-effectiveness without affecting surveillance coverage. We tested this hypothesis by choosing four potential forest and urban lepidopteran pest species that are present in Europe but not yet in New Zealand and many other countries. We deployed traps in central and southern Europe with single lures or all possible species combinations (up to four lures per trap). There was only limited interference, apparently due to trap saturation, but no evidence for interspecific repellency among lures for gypsy moth, Lymantria dispar, fall webworm, Hyphantria cunea, pine processionary moth, Thaumetopoea pityocampa, and pine shoot moth, Rhyacionia buoliana. To assess what factors may be important in species compatibility/suitability for multiple-species trapping, we combined our results with those of previous studies conducted by the United States Department of Agriculture. For 75 combinations of pheromones, tested singly or in combination, 19 % showed no effect on trap catch for any of the species tested. In the other cases, either one or both species showed a reduction in trap catch. However, few lure combinations caused complete or nearly complete suppression. For most combinations, catches were still sufficiently high for detection purposes. Species from the same superfamily exhibited more interference than more distantly related species. Together, these results suggest that there are opportunities to improve the range of exotic pests under surveillance, at little additional cost, by multiple-species trapping for which compatibility has been demonstrated.

TI Headspace Volatiles from 52 oak Species Advertise Induction, Species Identity, and Evolution, but not Defense SO JOURNAL OF CHEMICAL ECOLOGY LA English DT Article DE VOC; Volatile; Quercus; Aposematic; Green leaf volatiles; Macroevolution ID INDUCED PLANT VOLATILES; HERBIVORE; EMISSIONS; SPECIFICITY; SPECIALIST; SUFFICIENT; SELECTION; PATTERNS; TAXONOMY; INSECTS AB Leaf volatiles convey information about a plant to other organisms in their proximity. Despite increasing interest in understanding the relevance of volatile emissions for particular ecological interactions, there has been relatively little effort to assess generally what information volatile profiles transmit. We surveyed the volatile profiles of wounded and unwounded leaves of 52 oak (Quercus) species. We used phylogenetic comparison and multivariate techniques to assess in what circumstances oak individuals advertised their species identity, evolutionary history, direct defenses, or damage. We found that both species identity and evolutionary history were advertised when leaves were wounded, but species could not be differentiated by odor when leaves were not wounded. Various fatty-acid derivative compounds showed the strongest phylogenetic signal suggesting that they may best disclose taxonomic affiliations in oaks. We tested whether oak volatile composition or diversity advertised high defensive investment, but we found no evidence for this. Wounded leaves disclose much about an oak species' identity and taxonomic affiliation, but unwounded leaves do not. This is consistent with the idea that volatile information is targeted toward natural enemy recruitment. C1 [Pearse, Ian S.; Beck, John J.] Univ Calif Davis, Dept Entomol, Davis, CA 95616 USA.

However, some characteristics of Rubisco make it surprisingly inefficient and compromise photosynthetic productivity. For example, Rubisco catalyses a wasteful reaction with oxygen that leads to the release of previously fixed CO2 and NH3 and the consumption of energy during photorespiration. Furthermore, Rubisco is slow and large amounts are needed to support adequate photosynthetic rates. Consequently, Rubisco has been studied intensively as a prime target for manipulations to osupercharge' photosynthesis and improve both productivity and resource use efficiency. The catalytic properties of Rubiscos from diverse sources vary considerably, suggesting that changes in turnover rate, affinity, or specificity for CO2 can be introduced to improve Rubisco performance in specific crops and environments. While attempts to manipulate plant Rubisco by nuclear transformation have had limited success, modifying its catalysis by targeted changes to its catalytic large subunit via chloroplast transformation have been much more successful. However, this technique is still in need of development for most major food crops including maize, wheat, and rice. Other bioengineering approaches for improving Rubisco performance include improving the activity of its ancillary protein, Rubisco activase, in addition to modulating the synthesis and degradation of Rubisco's inhibitory sugar phosphate ligands. As the rate-limiting step in carbon assimilation, even modest improvements in the overall performance of Rubisco pose a viable pathway for obtaining significant gains in plant yield, particularly under stressful environmental conditions.

Asymmetric conjoined twins, which consist of a normal embryo attached to a malformed-atrophic twin, were frequently encountered in both gynogenetic (90.7%) and outbred (38.2%) embryos. The monozygotic origin of these twins was determined using five microsatellite markers. Progeny of heterozygous parents for the microsatellite UNH159 were separated into sub-sets of twins and normal full-sibs. Consistent with previous reports, the normal embryo sub-set exhibited elimination of both types of homozygotes for the UNH159 genetic marker at 28 days after fertilization. Unexpectedly, this elimination was less frequent in twins. The UNH159 marker as well as RNA-binding motif protein, X-linked (rbmx), SRY-box containing gene 3 (sox3) and alpha-thalassemia/mental retardation syndrome X-linked (atrx) genes were mapped to linkage group 2. These gene orthologues are all located on the mammalian X chromosome and atrx is necessary for the X-chromosome inactivation.

Identification of the early instars using traditional, morphology-based keys is difficult because of their small size, similarity, and simplicity in external morphology. Information derived from molecular genetic data would augment the accurate identification of immature flies. Nine species of blow flies commonly found in southeastern Nebraska were used to examine the utility of molecular-based keys. Polymerase chain reactionrestriction fragment length polymorphisms (PCRRFLP) were investigated with 10 common, inexpensive, restriction enzymes from an amplicon of approximately 1500 bp spanning the mitochondrial cytochrome oxidase I gene. A simple molecular taxonomic key, comprising RFLP from the restriction enzymes HinfI and DraI, enabled the differentiation of all species used. Further development of PCRRFLP, including more extensive and intensive examination of blow flies, would benefit forensic laboratories in the accurate identification of evidence consisting of immature blow flies.

(Cubbage et al. 1995). We ask a similar question about the potential of southern forests to mitigate greenhouse gas (GHG) emissions by sequestering carbon. Because significant carbon sequestration potential occurs on individual nonindustrial private forest (NIPF) lands owned by individuals, the accuracy of projections depends on how NIPF landowners respond to prices and their ability and willingness to participate in carbon offset programs. Striving to produce a more realistic assessment of the potential for southern forests to sequester carbon in response to future markets or policies, we use National Woodland Owner Survey data from the Forest Inventory and Analysis program to link landowner demographic and behavioral data with forest conditions. We also examine barriers to NIPF participation in carbon offset programs and offer recommendations for overcoming those barriers.

Results from a thematic synthesis of literature germane to harvesters and forest managers indicate that many NTFPs have considerable markets but most are inadequately monitored, economically underregulated, and ecologically poorly understood. The people who harvest wild-grown NTFPs are often referred to as wildcrafters. Literature suggests that wildcrafters have historically been marginalized and are often reticent to share information or to participate in government-led initiatives. Additionally, forest managers and wildcrafters often are unable or unwilling to work together. Social networking has been suggested as a way to improve collaboration between the two stakeholders. Some examples of successful networks exist, but norms and priorities may inhibit greater participation. Asynchronous communication via the Internet and other wireless technology could improve the situation. Developing systematic inventory systems, designing NTH output reporting protocols, advancing forest farming, and improving access to information on NTFP markets, policies, and practices may also be useful. The need for improvement on all fronts is increasingly relevant because of growing demand for NTFPs. C1 [Vaughan, Ritchie C.; Munsell, John F.] Virginia Tech & State Univ, Blacksburg, VA USA.

Prospective evaluation of fuel treatment effectiveness allows for comparison of alternative treatment strategies in terms of socioeconomic and ecological impacts and facilitates analysis of tradeoffs across land-management objectives. Studies have yet to rigorously examine potential impacts to fire suppression expenditures associated with prior hazardous fuel reduction treatments. Such information would be helpful for federal land-management agencies struggling to contain escalating wildfire management costs. In this article we establish a methodology for estimating potential reductions in wildfire suppression costs. Our approach pairs wildfire simulation outputs with a regression cost model and quantifies the influence of fuel treatments on distributions of wildfire sizes and suppression costs. Our case study focuses on a landscape within the Deschutes National Forest in central Oregon that was selected to receive funding under the auspices of the Collaborative Forest Landscape Restoration Program. Results suggest substantial reductions in distributions of wildfire size and suppression cost on a per fire basis. Furthermore, because fewer ignitions become large fires on the treated landscape, distributions of annual area burned and annual suppression costs also shift downward because of fuel treatments. Results are contingent on four key factors: large-scale implementation of fuel treatments across the landscape, assumed treatment effectiveness over the duration of the analysis period, accuracy of wildfire and cost models, and accuracy of projected changes to fire behavior fuel models resulting from fuel treatments. We discuss strengths and limitations of the modeling approach and offer suggestions for future improvements and applications.

In addition to substitutions that may arise with other beverages, we account for substitutions between SSBs and 12 major food categories. Our main findings are that the tax would result in a decrease in store-bought energy of 24.3 kcal per day per person, which would translate into an average weight loss of 1.6 pounds during the first year and a cumulated weight loss of 2.9 pounds in the long run. We do not find evidence of substitution to sugary foods and show that complementary foods could contribute to decreasing energy purchases. Despite their significantly lower price elasticity, the tax has a similar effect on calories for the largest purchasers of SSBs. (C) 2012 Elsevier B.V. All rights reserved.

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

TI A multi-gene phylogeny provides additional insight into the relationships between several Ascosphaera species SO JOURNAL OF INVERTEBRATE PATHOLOGY LA English DT Article DE Ascosphaera; Chalkbrood; Bee disease; Multi-gene phylogeny; Pathogen evolution ID ALFALFA LEAFCUTTING BEE; ISOZYME CHARACTERIZATION; MEGACHILE-ROTUNDATA; SP-NOV; AGGREGATA; IDENTIFICATION; SEQUENCE; LARVIS; RDNA; ATRA AB Ascosphaera fungi are highly associated with social and solitary bees, with some species being pathogenic to bees (causing chalkbrood) while others are not, and proper identification within this genus is important. Unfortunately, morphological characterizations can be difficult, and molecular characterizations have only used one genetic region. We evaluated multiple phylogenies of the Ascosphaera using up to six loci: the Internal Transcribed Spacer (ITS) region, 18S rRNA, 28S rRNA, Elongation Factor-1 alpha (EF-1 alpha) the RNA polymerase II largest subunit (RPB1), and the second largest subunit (RPB2). The ITS sequence alone produced an inadequate phylogeny, and the addition of both the 18S and 28S rRNA loci to the ITS sequence produced a phylogeny similar to that based on all six genetic regions. For all phylogenies, Ascosphaera torchioi was in a separate clade that was the most basal, with a strong genetic similarity to Eremascus albus, introducing the possibility of paraphyly within Ascosphaera. Also, based on this new phylogeny, we now suggest that the Apis mellifera (honey bee) pathogens arose within a group of saprophytes, and the Megachile (leafcutting bees) pathogens arose separately.

In general, the quantity of cellulose in cotton fibers increases rapidly, thus it leads to compositional, structural and physical attribute variations among the fibers with shorter and longer growth periods. This article discusses recent progress in applying the Fourier transform infrared (FTIR) spectroscopic technique to characterize these differences, to discriminate immature fibers from mature fibers, to assess fiber maturity and crystallinity and also to unravel the band assignments in crystalline and amorphous celluloses. The results were achieved through the use of various strategies, including wet chemical analysis, principal component analysis (PCA), simple algorithm development, two-dimensional correlation analysis and other independent fiber tests. Of particular interest is that, in general, immature fibers might have the characteristics of less than 21-28 dpa, M-IR < 0.58 (in the maturity range of 0 to 1.0) and CIIR < 42% (in the crystallinity range of 0 to 100%).

The purpose of this study was to identify and assess the pathogenicity of several anamorph species of the Botryosphaeriaceae, including Diplodia corticola, Dothiorella iberica and Diplodia agrifolia sp. nov., that were recovered consistently from symptomatic tissues. Species were identified morphologically and by phylogenetic analyses of the complete sequence of the internal transcribed spacer (ITS) of the rDNA and partial sequences of beta-tubulin and elongation factor (EF1-alpha) genes. Results from morphological assessments and phylogenetic analyses support the erection of a new species closely related to D. mutila, described herein as Diplodia agrifolia sp. nov. Pathogenicity of all species was verified by wound inoculation of 1 y old coast live oak seedlings under controlled conditions. Isolates of D. corticola were the most aggressive tested, and isolates of D. agrifolia were the second most aggressive. Both species caused bleeding symptoms on inoculated seedlings. Seedlings inoculated with D. corticola died within 4 wk, with the pathogen progressing up and down through the xylem in advance of living phloem and moving throughout the taproot in 70% of inoculated seedlings. Colonization and re-isolation was successful for all species. All three fungal species represent newly recorded fungal pathogens of coast live oak in California. Results from the pathogenicity test suggest that these fungi play a role in the decline of coast live oaks throughout southern California.

It is a serious problematic weed in Hawai'i and has naturalized in many other countries. Biological control is being considered as a means to suppress it by introducing natural enemies from Asia, its native region. In this paper, we report 62 herbivorous insect species in 22 families that were collected on R. ellipticus during 2006-2010 in China. Two leaf-rolling moth species, Epinotia ustulana and Epiblema tetragonana; two warty beetle species, Chlamisus setosus and Chlamisus sp.; two flea beetle species in the genus Chaetocnema; four unidentified weevil species; five unidentified buprestids; one pyralid species; and one sawfly species were considered important. We also report results of preliminary host-range determinations for some of them. In addition, we summarize the literature on natural enemies associated with Rubus species in Asia, which encompasses 50 arthropod species in 14 families and 63 fungi species in 18 orders.

TI Incomplete transfer of accessory loci influencing SbMATE expression underlies genetic background effects for aluminum tolerance in sorghum SO PLANT JOURNAL LA English DT Article DE sorghum; aluminum tolerance; multi-drug and toxic compound extrusion family; transporter protein; alternative splicing; gene expression ID MESSENGER-RNA DECAY; MALATE TRANSPORTER; ACTIVATED CITRATE; CIS MUTATIONS; ACID SOILS; ARABIDOPSIS; RESISTANCE; WHEAT; MAIZE; RICE AB Impaired root development caused by aluminum (Al) toxicity is a major cause of grain yield reduction in crops cultivated on acid soils, which are widespread worldwide. In sorghum, the major Al-tolerance locus, Alt(SB), is due to the function of SbMATE, which is an Al-activated root citrate transporter. Here we performed a molecular and physiological characterization of various Alt(SB) donors and near-isogenic lines harboring various Alt(SB) alleles. We observed a partial transfer of Al tolerance from the parents to the near-isogenic lines that was consistent across donor alleles, emphasizing the occurrence of strong genetic background effects related to Alt(SB). This reduction in tolerance was variable, with a 20% reduction being observed when highly Al-tolerant lines were the Alt(SB) donors, and a reduction as great as 70% when other Alt(SB) alleles were introgressed. This reduction in Al tolerance was closely correlated with a reduction in SbMATE expression in near-isogenic lines, suggesting incomplete transfer of loci acting in trans on SbMATE. Nevertheless, Alt(SB) alleles from the highly Al-tolerant sources SC283 and SC566 were found to retain high SbMATE expression, presumably via elements present within or near the Alt(SB) locus, resulting in significant transfer of the Al-tolerance phenotype to the derived near-isogenic lines. Allelic effects could not be explained by coding region polymorphisms, although occasional mutations may affect Al tolerance. Finally, we report on the extensive occurrence of alternative splicing for SbMATE, which may be an important component regulating SbMATE expression in sorghum by means of the nonsense-mediated RNA decay pathway.

Surveillance to monitor mosquito populations during the inter-epidemic period (IEP) and viral activity in these vectors is critical to informing public health decisions for early warning and control of the disease. Using a combination of field bioassays, electrophysiological and chemical analyses we demonstrated that skin-derived aldehydes (heptanal, octanal, nonanal, decanal) common to RVF virus (RVFV) hosts including sheep, cow, donkey, goat and human serve as potent attractants for RVFV mosquito vectors. Furthermore, a blend formulated from the four aldehydes and combined with CO(2-)baited CDC trap without a light bulb doubled to tripled trap captures compared to control traps baited with CO2 alone. Our results reveal that (a) because of the commonality of the host chemical signature required for attraction, the host-vector interaction appears to favor the mosquito vector allowing it to find and opportunistically feed on a wide range of mammalian hosts of the disease, and (b) the sensitivity, specificity and superiority of this trapping system offers the potential for its wider use in surveillance programs for RVFV mosquito vectors especially during the IEP.

TI Spatial Redistribution of Nitrogen by Cattle in Semiarid Rangeland SO RANGELAND ECOLOGY & MANAGEMENT LA English DT Article DE grazing management; Great Plains; large herbivores; nitrogen cycling; semiarid grassland; shortgrass steppe ID COLORADO SHORTGRASS STEPPE; ELEVATED CO2; N2O FLUXES; LONG-TERM; CARBON; LIMITATION; ECOSYSTEMS; LANDSCAPE; DYNAMICS; PRAIRIE AB Nitrogen (N) availability can strongly influence forage quality and the capacity for semiarid rangelands to respond to increasing atmospheric CO2. Although many pathways of nitrogen input and loss from rangelands have been carefully quantified, cattle-mediated N losses are often poorly understood. We used measurements of cattle N consumption rate, weight gains, and spatial distribution in shortgrass rangeland of northeastern Colorado to evaluate the influence of cattle on rangeland N balance. Specifically, we estimated annual rates of N loss via cattle weight gains and spatial redistribution of N into pasture corners and areas near water tanks, and used previous studies to calculate ammonia volatilization from urine patches. Using measurements of plant biomass and N content inside and outside grazing cages over 13 yr, we estimate that cattle stocked at 0.65 animal unit months (AUM) . ha(-1) consumed 3.34 kg N . ha(-1) . yr(-1). Using an independent animal-based method, we estimate that cattle consumed 3.58 kg N . ha(-1) . yr(-1) for the same stocking rate and years. A global positioning system tracking study revealed that cattle spent an average of 27% of their time in pasture corners or adjacent to water tanks, even though these areas represented only 2.5% of pasture area. Based on these measurements, we estimate that cattle stocked at 0.65 AUM . ha(-1) during the summer can remove 0.60 kg N . ha(-1) in cattle biomass gain and spatially redistribute 0.73 kg N . ha(-1) to areas near corners and water tanks. An additional 0.17 kg N . ha(-1) can be lost as NH3 volatilization from urine patches. Cumulatively, these cattle-mediated pathways (1.50 kg N . ha(-1)) may explain the imbalance between current estimates of atmospheric inputs and trace gas losses. While NOx emission remains the largest pathway of N loss, spatial N redistribution by cattle and N removed in cattle biomass are the second and third largest losses, respectively. Management of cattle-mediated N fluxes should be recognized as one means to influence long-term sustainability of semiarid rangelands.

This balance varies by the specific questions being asked of the data. Here, we tested a FOV-resolution question by comparing ground cover measured in the field with the use of point-intercept transects with similar data measured from 50-mm-per-pixel (mmpp) VLSA imagery of the same locations. Particular care was given to spatial control of ground and aerial sample points from which observations were made, yet percent cover estimates were very different between methods. An error budget was used to calculate error of location and error of quantification. These results indicated location error (43.5%) played a substantial role with significant quantification error (21.6%) also present. We conclude that 1) although the georectification accuracy achieved in this project was actually quite good, the level of accuracy required to match ground and aerial sample points represents an unrealistic expectation with currently available positioning technologies, 2) 50-mmpp VLSA imagery is not adequate for accurate species identification or cover assessments of plant functional groups, and 3) the balance between resolution and FOV needs is best addressed by using multiple cameras to acquire nested imagery at multiple VLSA resolutions simultaneously. We recommend ground cover be measured from 1-mmpp imagery and that the imagery be nested in lower-resolution, larger FOV images simultaneously acquired.

We used four rumen-fistulated steers to evaluate both techniques. Four enclosures in a mixed-conifer rangeland were used. Each enclosure contained two 0.25-ha paddocks that were either nonstocked or stocked by cattle to remove 32 +/- 4% of standing crop. We recorded bite-count data during foraging bouts for each steer in each paddock, and then evacuated each rumen following each foraging bout during summer (August). Paddocks stocked prior to each 20-min trial had a reduced (P < 0.05) quantity of forage consumed regardless of technique. BC and RE gave similar (P > 0.10) results on diet quantity and digestibility. However, BC-derived estimates were lower (P < 0.05) for crude protein (CP), acid detergent fiber (ADF), ash, and neutral detergent fiber (NDF). In summary, although BC has the advantage of not requiring rumen-fistulated animals, it did not yield comparable results to RE under range conditions with dense and diverse vegetation. Therefore, investigators should calibrate bite-count technique against fistula technique to solve any accuracy problem in their specific experimental conditions whenever possible.

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

TI The Role of Wilderness Protection and Societal Engagement as Indicators of Well-Being: An Examination of Change at the Boundary Waters Canoe Area Wilderness SO SOCIAL INDICATORS RESEARCH LA English DT Article DE Emerging adults; Ecosystem services; Under-represented populations; Quality of life; Protected nature AB A societal decision to protect over 9 million acres of land and water for its wilderness character in the early 1960s reflected US wealth in natural resources, pride in the nation's cultural history and our commitment to the well-being of future generations to both experience wild nature and enjoy benefits flowing from these natural ecosystems. There is no question that our relationship with wilderness has changed. Individually it is probably quite easy to examine differences in the role wilderness plays in the quality of our lives today compared to some previous time. But how the role of wilderness protection has changed for society is more difficult to describe. In only a few places do we have data across multiple decades that would allow us to even examine how users or their use may have changed over time. At the Boundary Waters Canoe Area Wilderness in northern Minnesota we are fortunate to have multiple studies that can give us some 40 years of insight into how some aspects of use have changed there. For example, an analysis of results of visitor studies at the Boundary Waters Canoe Area Wilderness in 1969, 1991 and 2007 reveal some big differences in who is out there today, most notably the presence of a much older, more experienced and better educated user population, almost exclusively white and predominantly male. It is time to decide whether the best thing for wilderness and or society is to try to restore historic patterns of use (to include younger people, the less wealthy and lower educated) in greater numbers, to try to identify new markets within growing underrepresented populations, or adapt our perception of wilderness stewardship to better include planning for emerging social values of a new generation with other indicators of well-being. A growing population with greater dependence on ecosystem services provided by protected nature could lead to wilderness protection becoming an important quantitative and qualitative element of quality of life indices in the very near future.

Locoweeds contain the toxic indolizidine alkaloid swainsonine, which is produced by the endophytic fungi Undifilum species. Previously we reported that swainsonine concentrations differ between populations of Oxytropis sericea. We hypothesized that the genotype of the plant, endophyte, or an interaction of the two may be responsible for the differences in swainsonine concentration between populations of O. sericea. To test this hypothesis, plants derived from seeds collected at each location were grown in a common garden, Undifilum oxytropis isolates from each location were cultured and grown in a common environment, and a plant genotype by endophyte cross inoculation was performed. Here we show that the genotype of the endophyte is responsible for the differences in swainsonine concentrations observed in the two populations of O. sericea. Published by Elsevier Ltd.

The allelopathic microorganisms are grouped separately from typical phytopathogens because they do not follow classical disease cycles involving aggressive infection and colonization of plant tissues. Allelopathic microorganisms passively suppress or inhibit the plant root growth through production of variety of phytotoxic compounds absorbed by the plant, or they compete for limited plant nutrients in the rhizosphere. Thus it is important to understand the effects of allelopathic microorganisms on plant growth and discern these from traditional phytopathogens so that appropriate management of plant growth problems can be implemented based on this knowledge. The purpose of this paper is to provide basic information on protocol development of bioassays to identify allelopathic microorganisms associated with plants. Guidance provided by the general procedures is presented as templates for devising custom protocols to aid in eventual development of standardized bioassays for consistent detection and characterization of allelopathic microorganisms, for which little information and reliable data currently exist. The use of improved bioassays that yield reproducible results will enhance comprehension of the effects of allelopathic microorganisms on plant growth and increase the overall perspective of functional biology and ecology of the rhizosphere microbial community beyond general descriptions of interactions between plants and soilborne phytopathogens.

The virus was isolated from 15 horses, 1 llama, and pheasants in three separate captive flocks. One wild turkey, screened before translocation, also showed exposure to the virus in January 2010. Two pools of Culiseta melanura (Coquillett) tested positive for EEEv during routine seasonal surveillance in York County in September, but none of the mosquitoes collected during rapid response surveys tested positive. There were more Cs. melanura in July, August, and September 2009 than in preceding (2006-08) and subsequent (2010-11) years. August and September Cs. melanura abundances were correlated with July rainfall, and abundance of all species combined was correlated with total rainfall for the meteorological summer. This outbreak represents a substantial expansion of the range of EEEv activity in northern New England.

Many species are valued because they provide ecosystem services, including biological control, pollination and decomposition, or because they are of conservation interest. Some arthropods reduce crop yield and quality, and conventional chemical pesticides, biological control agents and genetically engineered (GE) crops are used to control them. A common concern addressed in the ecological risk assessment (ERA) that precedes regulatory approval of these pest control methods is their potential to adversely affect valued non-target arthropods (NTAs). A key concept of ERA is early-tier testing using worst-case exposure conditions in the laboratory and surrogate test species that are most likely to reveal an adverse effect. If no adverse effects are observed in those species at high exposures, confidence of negligible ecological risk from the use of the pest control method is increased. From experience with chemical pesticides and biological control agents, an approach is proposed for selecting test species for early-tier ERA of GE arthropod-resistant crops. Surrogate species should be selected that most closely meet three criteria: (i) Potential sensitivity: species should be the most likely to be sensitive to the arthropod-active compound based on the known spectrum of activity of the active ingredient, its mode of action, and the phylogenetic relatedness of the test and target species; (ii) Relevance: species should be representative of valued taxa or functional groups that are most likely to be exposed to the arthropod-active compound in the field; and (iii) Availability and reliability: suitable life-stages of the test species must be obtainable in sufficient quantity and quality, and validated test protocols must be available that allow consistent detection of adverse effects on ecologically relevant parameters. Our proposed approach ensures that the most suitable species are selected for testing and that the resulting data provide the most rigorous test of the risk hypothesis of no adverse effect in order to increase the quality and efficiency of ERAs for cultivation of GE crops.

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

Its main objective was to contribute to Soil Moisture and Ocean Salinity (SMOS) mission validation and the prelaunch assessment of the proposed Soil Moisture Active and Passive (SMAP) mission. During CanEx-SM10, SMOS data as well as other passive and active microwave measurements were collected by both airborne and satellite platforms. Ground-based measurements of soil (moisture, temperature, roughness, bulk density) and vegetation characteristics (leaf area index, biomass, vegetation height) were conducted close in time to the airborne and satellite acquisitions. Moreover, two ground-based in situ networks provided continuous measurements of meteorological conditions and soil moisture and soil temperature profiles. Two sites, each covering 33 km x 71 km (about two SMOS pixels) were selected in agricultural and boreal forested areas in order to provide contrasting soil and vegetation conditions. This paper describes the measurement strategy, provides an overview of the data sets, and presents preliminary results. Over the agricultural area, the airborne L-band brightness temperatures matched up well with the SMOS data (prototype 346). The radio frequency interference observed in both SMOS and the airborne L-band radiometer data exhibited spatial and temporal variability and polarization dependency. The temporal evolution of the SMOS soil moisture product (prototype 307) matched that observed with the ground data, but the absolute soil moisture estimates did not meet the accuracy requirements (0.04 m(3)/m(3)) of the SMOS mission. AMSR-E soil moisture estimates from the National Snow and Ice Data Center more closely reflected soil moisture measurements.

Biological efficiency in the field is higher if only sterile males are released in SIT programs and production costs are also reduced. Sexing strains developed in the Mediterranean fruit fly Ceratitis capitata (medfly) through classical genetics are immensely beneficial to medfly SIT programs but exhibit reduced fertility and fitness. Moreover, transfer of such classical genetic systems to other tephritid species is difficult. Transgenic approaches can overcome this limitation of classical genetic sexing strains (GSSs), but had resulted so far in transgenic sexing strains (TSSs) with dominant lethality at late larval and pupal stages. Here we present a transgene-based female-specific lethality system for early embryonic sexing in medfly. The system utilizes the sex-specifically spliced transformer intron to restrict ectopic mRNA translation of the pro-apoptotic gene hid(Ala5) to females only. The expression of this lethal effector gene is driven by a tetracycline-repressible transactivator gene tTA that is under the control of promoters/enhancers of early-acting cellularization genes. Despite observed position effects on the sex-specific splicing, we could effectively establish this early-acting transgenic sexing system in the medfly C capitata. After satisfactory performance in large scale tests. TSSs based on this system will offer cost-effective sexing once introduced into SIT programs. Moreover, this approach is straight forward to be developed also for other insect pest and vector species. (C) 2012 Elsevier Ltd. All rights reserved.

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

TI Dimerization and protease resistance: New insight into the function of PR-1 SO JOURNAL OF PLANT PHYSIOLOGY LA English DT Editorial Material DE Common wheat; Defense pathways; Heterologous expression; Pathogenesis-related proteins; Protein dimerization; Protease resistance ID PATHOGENESIS-RELATED PROTEINS; DEFENSE; INFECTION; SUPERFAMILY; MECHANISM; ANTIGEN; GAPR-1; P14A AB The group 1 pathogenesis-related (PR-1) proteins have long been considered hallmarks of hypersensitive response/defense pathways in plants, but their biochemical functions are still obscure despite resolution of the NMR/X-ray structures of several PR-1-like proteins, including P14a (the prototype PR-1). We report here the characterization of two basic PR-1 proteins (PR-1-1 and PR-1-5) recently identified from hexaploid wheat (Triticum aestivum). Both proteins were expressed in Pichia pastoris as a single major species of similar to 15 kDa. Sequence identity of the expressed PR-1 proteins was verified by MALDI-TOF/TOF analysis. Accumulation of the native PR-1-5 protein in pathogen-challenged wheat was confirmed by protein gel blot analysis. Low-temperature SDS-PAGE and yeast two-hybrid assays revealed that PR-1-1 exists primarily as a monomer whereas PR-1-5 forms homodimers. Both PR-1 proteins are resistant to proteases compared to bovine serum albumin, but PR-1-1 shows resistance mainly to subtilisin and protease K (serine proteases) whereas PR-1-5 shows resistance to subtilisin, protease K and papain (a cysteine protease). Site-specific mutations at the five putative active sites in the PR-1 domain all affected dimerization, with the mutations at Glu-72 and Glu-102 (in the PR-1-5 numeration) also diminishing protease resistance. Sequence analysis revealed that the Glu-72 and Glu-102 residues are located in motif-like sequences that are conserved in both PR-1 and the human apoptosis-related caspase proteins. These findings prompt us to examine the function of PR-1 for a role in protease-mediated programmed cell death pathways in plants. (c) 2012 Elsevier GmbH. All rights reserved.

Assessment of wind erosion for the agricultural land management systems in APEC is needed to determine which systems are most sustainable. In this study, the Revised Wind Erosion Equation (RWEQ) with a geographic information system method has been applied to estimate alternative wind erosion control measure scenarios. Simulation results of alternative agricultural land management scenarios for the period 2000 to 2008 indicated that the most severe potential wind eroded areas were scattered in the Horqin Sands, Hunshan Dake Sands, and Mu Us Sands. The scenarios results further showed that most croplands in the APEC would suffer severe wind erosion if no effective measures were implemented. The results further indicated that conservation tillage, no-tillage after harvest, and retention of crops residues until sowing season in the following year produced the most favorable, impact on reducing wind erosion. Shrub barriers reduced wind erosion effectively, but irrigation twice per year could not reduce the wind erosion level markedly in the APEC. Even though combinations of conservation tillage;wind barriers, and irrigation could greatly reduce. wind erosion, most farmlands in the APEC are still at the risk of degradation.

TI Pilot-scale vadose zone biobarriers removed nitrate leaching from a cattle corral SO JOURNAL OF SOIL AND WATER CONSERVATION LA English DT Article DE bioremediation; groundwater; methemoglobinemia; sawdust; soybean oil; vadose zone ID SEPTIC-SYSTEM NITRATE; VEGETABLE-OIL; GROUNDWATER; DENITRIFICATION; CONTAMINATION; BARRIER; EFFLUENT; WATER AB Agricultural activities that involve animal wastes can result in the contamination of subsurface soils by nitrates (NO3). In saturated or nearly saturated soils, microbial biobarriers are a common method used to remove contaminants from water. This study evaluated the presence of NO3 in the soil profile beneath a cattle corral and the use of biobarriers to prevent the movement of NO3 through these semiarid vadose zone soils. Soils from beneath the pen contained as much as 330 mg kg(-1) (330 ppm) nitrate-nitrogen (NO3-N), and a well located similar to 50 m (similar to 55 yd) from the pens contained 18 mg L-1 (18 ppm) NO3-N, indicating that denitrification activity in the surface soils of the corral had not prevented NO3 from migrating into deeper soils where denitrification activity was limited by electron donor (i.e., carbon [C] substrate) availability. Biobarriers used to intercept the percolating soil water contaminated with NO3 included a control that contained only sand and treatment biobarriers that contained sand blended with sawdust, soybean (Glycthe max L.) oil, or sawdust and soybean oil. A distinctive attribute of the study was that the biobarriers were installed near the surface of a semiarid soil well above the water table. Results show that all of the treatment biobarriers removed NO3 from percolating soil water. Water collected from beneath the control barriers contained 99 mg L-1 (99 ppm) NO3-N While NO3-N levels in water that moved through the sawdust, soybean oil, and sawdust plus soybean oil barriers averaged 4, 17, and 28 mg L-1 (4, 17, and 28 ppm) NO3-N for removal efficiencies of 96%, 83%, and 72%, respectively. In waters from the sawdust plus soybean oil barriers, 6.8 mg L-1 (6.8 ppm) nitrite-N was detected. With all three substrate combinations, biobarrier life was such that barriers of this type should last for many years before substrates need to be replaced.

Herbaceous peonies (Paeonia section Paeonia), tree peonies (Paeonia section Moutan), and intersectional crosses between the two types (Itoh Paeonia hybrids) are of interest to gardeners, growers, and nursery producers. Thousands of peony cultivars exist and identity is traditionally determined by experienced horticulturists knowledgeable in plant and bloom characteristics. With DNA extraction possible during any time of the year, molecular markers can provide genotype identity confirmation for dormant roots or mature post-bloom plants. The primary objective of our research was to rapidly and inexpensively develop microsatellite markers in a range of Paeonia species using barcoded Illumina libraries. A secondary objective was to apply these simple sequence repeat (SSR) markers to fingerprint 93 accessions that include tree, intersectional, and herbaceous peonies. We used 21 primers to distinguish cultivars and their close relatives. Also from our sequence information, greater than 9000 primers were designed and are made available.

For example, from the top of canopy, we predicted canopy height (r(2) = 0.87), canopy cover (r(2) = 0.83), basal area (r(2) = 0.82), shrub cover (r(2) = 0.62), shrub height (r(2) = 0.59), combined fuel loads (r(2) = 0.48), and fuel bed depth (r(2) = 0.35). While the general fuel types were predicted accurately, specific surface fuel model predictions were poor (76 percent and <50 percent correct classification, respectively) using all algorithms. These fuel components are critical inputs for wildfire behavior modeling, which ultimately support forest management decisions. This comprehensive examination of the relative utility of lidar and optical imagery will be useful for forest science and management.

A study conducted from 2002 to 2005 by USDA-ARS and the Univ. of GA assessed the effects of cover crops on soil physical properties and C/N relationships in a sandy coastal plain soil. The cropping systems were (A) sunn hemp (Crotalaria juncea L.), crimson clover (Trifolium incarnatum L.), sweet corn (Zen mays L); (B) sunn hemp, fallow, sweet corn; (C) fallow, crimson clover, sweet corn; (D) fallow, fallow, sweet corn; or (E) fallow, fallow, fallow. Three N rates (0, 67, or 133 kg ha(-1)) were tested on the corn for cropping systems A, B, and C, while N rates of 0, 67, 133, 200, and 267 kg ha(-1) were used for cropping system D. No N was applied to cropping system E. Soil physical property measurements made on minimally disturbed cores (7.6 cm height x 7.6 cm diameter) collected from the top 7.6 cm both within the row and interrow of each plot seven times during the study included bulk density (BD), saturated hydraulic conductivity (K-s), and volumetric soil moisture content (theta) over a range of matric suctions. Carbon/nitrogen levels were determined from samples of the top 2.5 cm of soil collected quarterly. Three year mean biomass added to the soil from sunn hemp ranged from 6.9 to 9.8 Mg ha(-1), while that from crimson clover ranged from 3.3 to 5.0 Mg ha(-1). The input of cover crop biomass increased soil C (0.3-4.7 mg g(-1)) and N (0.1-0.5 mg g(-1)), which contributed to improvements in soil structure and fertility. Significantly greater C (2.2 mg g(-1) vs. 1.8 mg g(-1)), lower BD (1.71 Mg m(-3) vs. 1.73 Mg m(-3)) and greater theta at field capacity (0.126 vs. 0.113 cm(3) cm(-3)) were found in the rotations with sunn hemp as crop I as compared to rotations with fallow as crop 1. There were significant differences in BD, K-s, and theta between soil in the rows and that in the interrows for all treatments. In general, BD were lower, K-s were greater, and theta were greater in the rows than in the interrows. Overall the study indicated that high residue input from fall and winter cover crops is important for adding C, retaining plant-available N in organic matter, increasing fertilizer use efficiency, and improving soil physical properties in the very sandy soils of the southeastern (SE) USA coastal plain region.

TI A simple novel measure of passive transfer of maternal immunoglobulin is predictive of preweaning mortality in piglets SO VETERINARY JOURNAL LA English DT Article DE Piglet; Mortality; Immunoglobulin; Immunocrit; Colostrum; Parity ID ENERGY-METABOLISM; NEWBORN CALVES; NEONATAL PIGS; COLOSTRUM; SERUM; SOWS; IGG; SURVIVAL; RECEPTOR; MILK AB Two factors that contribute to preweaning mortality in piglets are the initiation of lactation by sows and their ability to nurse their piglets. The objective of this study was to determine if the quantification of the transfer of immunoglobulins (Igs) from sow to piglet could act as a measure of these sow factors in terms of their influence on preweaning mortality. To measure passive transfer, a simple, rapid Ig immunocrit method was developed. For validation, the smallest piglets from 204 gilts were sacrificed on day 1 after birth and blood was collected. Piglet serum Ig concentrations were measured three ways: (I) by protein A sepharose precipitation, SDS-PAGE, and densitometry of the IgG heavy chain; (2) by precipitation of Ig with (NH4)(2)SO4 followed by spectrophotometric measurement; and (3) by precipitation of Ig with (NH4)(2)SO4 and measurement of the ratio of precipitate to sample volume using a hematocrit microcapillary (the Ig immunocrit method). Results from the (NH4)(2)SO4 methods correlated (r = 0.86) with those obtained using SDS-PAGE. Day 1 weights and immunocrit ratios and preweaning survival data were then collected from every piglet from first (n = 90), and second (n = 145) parity sows. Bodyweight and immunocrit ratios accounted for 4.8% and 16.7% (P < 0.01) of the variation in preweaning mortality, respectively. Litter average immunocrit ratios were not correlated with preweaning mortality. In conclusion, the Ig immunocrit method is a simple, rapid measure of passive transfer from sow to piglet, and is useful in assessing the initiation of colostrum and the nursing ability of sows, and the effect of these events on preweaning piglet mortality.

Field testing was conducted on 20 red pine (Pinus resinosa) trees and 10 freshly cut red pine logs at a 45-yr-old plantation stand in Arena, WI. Acoustic velocities of the red pine trees and logs and the ambient temperatures were monitored for 12 consecutive months. Results indicated that ambient temperature had a significant effect on acoustic velocities of trees and logs in winter when temperatures were below the freezing point. Acoustic velocities increased dramatically as ambient temperature dropped to below 0 degrees C, but the increase became less significant when the temperature decreased to below -2.5 degrees C. Above the freezing point, acoustic velocities were less sensitive to ambient temperature changes. From a practical standpoint, acoustic velocities of trees and logs measured at different climates and seasons can be adjusted to a standard temperature if measurements are conducted well above or well below freezing temperatures. However, measurements conducted around freezing temperatures could cause complications in making temperature adjustments. Users should avoid conducting field acoustic testing when wood temperature is around the freezing point. C1 [Gao, Shan; Wang, Lihai] NE Forestry Univ, Coll Engn & Technol, Harbin, Peoples R China.

Surface chemical and thermal mechanical behavior play an important role in the manufacturing process of bamboo composites and pellets. In this study, moso bamboo was treated by sodium hydrate solution and acetic acid solution. Surface chemical and dynamic mechanical properties of bamboo were determined using Fourier transform infrared spectroscopy and dynamic mechanical thermal analysis, respectively. Results showed that the main polar chemical groups of the outer layer of bamboo (OB) included hydroxyl group (O-H) and ester carbonyl (C=O). Some new polar chemical groups appeared on the inner layer of the bamboo surface (MB) such as aromatic ethers (C-O-C) and phenolic hydroxyl (C-O). The chemical group difference of OB and MB confirms that there was a waxy layer on the OB surface. Nonpolar chemical groups decreased and polar chemical groups increased on the OB surface when it was treated by acetic acid solution. The waxy layer of the OB surface was removed and the lignin structure was also destroyed by sodium hydrate solution. The general feature of thermal mechanical properties with temperature was similar to cellulosic materials for OB, OB-NaOH(OB treated by sodium hydrate solution), and OB-acetic (OB treated by acetic acid solution). A lower storage modulus of OB-NaOH and OB-acetic was helpful to improve physical properties of bamboo pellets. There was an alpha transition (alpha(1)) peaking at about 65 degrees C for OB. The second major relaxation (alpha(2)) occurred at 35 degrees C. The alpha(1) and alpha(2) transition temperature of OB changed when it was treated by chemical agents. This information is very important for using bamboo to manufacture composites and pellets.

Stand, site, and soil measurements collected in the field and remotely through geographical information system (GIS) data layers were used to model dynamic modulus of elasticity (DMOE) in those trees. The best fit linear model developed resulted in an adjusted R-2 = 0.52 for predictions of individual tree DMOE and an R-2 = 0.85 for predictions averaged on a stand basis, The linear model used was mean annual increment(-1), total tree height, and a GIS-based estimate of soil bulk density. Logical models were also developed to predict membership in dichotomous DMOE categories with 71-82% selected trees meeting their respective DMOE criteria. The inverse relationship between soil bulk density and DMOE could be explained by the soil tree moisture interactions know as least limiting water range. C1 [Morrow, C. D.; Gorman, T.

Temporal dynamics are critical in understanding how relationships form and change over time but rarely are studied explicitly in animal groups. Social network approaches are useful in describing association patterns and provide promising tools for investigating the dynamics of change in social structure but have rarely been used to quantify how animal associations change over time. In this study, we describe and test a framework for temporal analysis of social structure. We propose an analytical framework of methods that integrates across social scales and comparatively analyses change in social structure across multiple types of social association. These methods enable comparisons in groups that differ in size and are flexible to allow application to weighted and unweighted networks, where ties can be directed or undirected, and relationships can be symmetric or asymmetric. We apply this analytical framework to temporal social network data from experimentally formed captive groups of monk parakeets, Myiopsitta monachus, to both evaluate our analysis methods and characterize the social structure of this species. We compared dynamics of dyadic network formation, ego network formation and global network stabilization patterns across neutral, affiliative and agonistic associations. We found that social structure of captive monk parakeets formed and stabilized over a short period, but patterns differed by social association type. We also found evidence for consistency in the temporal dynamics of formation and stabilization of social structure between replicate social groups. Our analysis methods successfully identified change in social structure that corresponded well with qualitative observations. This framework is likely to be useful in characterizing patterns of temporal dynamics in social structure in longitudinal data in wide variety of social systems and species.

TI The Geographic Distribution of Rhagoletis pomonella (Diptera: Tephritidae) in the Western United States: Introduced Species or Native Population? SO ANNALS OF THE ENTOMOLOGICAL SOCIETY OF AMERICA LA English DT Article DE apple maggot fly; black hawthorn; English hawthorn; red hawthorn ID APPLE MAGGOT FLY; CHERRY FRUIT-FLY; HOST-PLANT USE; WASHINGTON-STATE; MANAGEMENT AB The apple maggot fly, Rhagoletis pomonella Walsh (Diptera: Tephritidae), is a major pest of commercially grown domesticated apple (Malus domestica Borkhausen) in North America. The shift of the fly from its native host hawthorn (Crataegus mollis) to apple in the eastern United States is often cited as an example of incipient sympatric speciation in action. However, R. pomonella is also present in the Pacific Northwest region of the United States where it infests apple, native black hawthorn (Crataegus douglasii), and introduced English ornamental hawthorn (C. monogyna). It is believed that R. pomonella was introduced to the Portland, OR, area via larval-infested apples from the east. The fly subsequently spread through the region, shifting onto black hawthorn and ornamental hawthorn as additional hosts as it spread. It is also possible, however, that R. pomonella is native to black hawthorn in the Pacific Northwest and switched to infest apple and ornamental hawthorn after the introduction of these two alternative hosts to the region. Here, we document the distribution of R. pomonella through the Pacific Northwest and Rocky Mountain states of the western United States to help clarify the origin(s) of the fly outside the eastern United States. We report a distribution pattern consistent with the hypothesis that R. pomonella was introduced to the Pacific Northwest via infested apples. In particular, the low levels or lack of C. douglasii-infesting R. pomonella east of the Cascade Mountains in the states of Washington, OR, and Idaho implies that the fly is not native on black hawthorn and is of recent origin. We discuss the evolutionary and applied implications of the results with respect to our current understanding of host race formation and control for R. pomonella.

While stylet-probing, L. hesperus discharge saliva consisting of lytic enzymes that facilitate extraoral digestion of host tissues. L. hesperus saliva primarily consists of polygalacturonases, alpha-amylases, and proteases, but salivary constituents other than these enzymes have not been documented. Improved knowledge of L. hesperus salivary proteins could lead to a better understanding of Lygus-host interactions, and aid in the development of crops that are resistant or tolerant to injury caused by Lygus spp. The objective of our study was to use mass spectrometry to identify salivary proteins of L. hesperus adults. Multiple polygalacturonases and proteases were identified from diet that was stylet-probed and fed upon by L. hesperus. Laccase, alkyl hydroperoxide reductase-like protein, glucose dehydrogenase, and xanthine dehydrogenase were identified in stylet-probed diets by using mass spectrometry, and laccase activity was confirmed using a colorimetric assay. This is the first study to identify laccase, glucose dehydrogenase, and xanthine dehydrogenase from L. hesperus saliva; we propose these enzymes target plant-defense compounds. Nearly 100 proteins from the bacterial plant pathogen, Pantoea ananatis and nine proteins from Serratia spp. were identified in stylet-probed diets. These results suggest L. hesperus may vector these plant pathogens. Our study adds to the list of documented L. hesperus salivary proteins, and provides information that will be useful for the further study of L. hesperus saliva and Lygus-microbe interactions.

We use this method to obtain a high-resolution (0.1 Hz) dataset representing the response of colony-reared melon flies, Bactrocera cucurbitae Coquillett, to cuelure [1-(p-acetoxyphenyl)-butan-3-one] at three different times of the day: morning (0900-1000 hours), mid (1200-1300 hours), and afternoon (1500-1600 hours), or all three times combined. Results consistently show a high and sustained response to cuelure in the morning period, a high but quickly decreasing response during the middle of the day and a low response in the afternoon. We propose possible reasons for the difference in response between the morning and middle of the day periods that could be investigated in future studies. The approach used here also can be used to study other important questions on the biology of tephritid fruit flies and other insects of similar size, particularly those involving their response to chemical lures.

Laboratory and field studies SO APPETITE LA English DT Article DE Variety; Energy intake; Overweight; Children; Habituation ID DIETARY VARIETY; NONOBESE WOMEN; CHILDREN; OBESITY; WEIGHT AB Greater food variety is related to increased energy intake, and one approach to reduce food intake is to reduce food variety. The effects of varying the variety of foods at the dinner meal to reduce energy intake was assessed in laboratory and field experiments. Experiment 1 randomly assigned 31 overweight children to one of three conditions that provided one laboratory meal per day over a week. Conditions were the SAME macaroni and cheese, SIMILAR types of macaroni and cheese, or a VARIETY of high-energy-dense foods. On days 1 and 5 all children consumed the same macaroni and cheese meal. Results showed significant differences in energy consumed between SAME and SIMILAR versus VARIETY from day 1 to 5, with SAME and SIMILAR decreasing and VARIETY increasing energy intake. Trials to habituation, a potential mechanism for the variety effect, showed the same pattern of between group differences as energy intake. Experiment 2 randomly assigned 30 overweight children to conditions that provided the SAME, SIMILAR or VARIETY of high-energy-dense entrees along with a variety of low-energy-dense dinner entrees to eat in their homes for 4 weeks. Results showed significant between group differences in energy intake across weeks, with significant decreases over weeks for the SAME and SIMILAR versus VARIETY groups. The pattern of results across the experiments shows the same pattern of reduction in energy intake if children eat the same or similar characteristics of foods (types of macaroni and cheese), which may provide ideas about how to develop dietary variety prescriptions that can reduce intake and be tested in clinical trials.

TI Coupling field and laboratory measurements to estimate the emission factors of identified and unidentified trace gases for prescribed fires SO ATMOSPHERIC CHEMISTRY AND PHYSICS LA English DT Article ID BIOMASS-BURNING EMISSIONS; TRANSFORM INFRARED-SPECTROSCOPY; VOLATILE ORGANIC-COMPOUNDS; GROUND-BASED MEASUREMENTS; UNITED-STATES; PARTICLE EMISSIONS; TROPICAL FOREST; SOUTH-AFRICA; ATMOSPHERIC CHEMISTRY; MASS-SPECTROMETRY AB An extensive program of experiments focused on biomass burning emissions began with a laboratory phase in which vegetative fuels commonly consumed in prescribed fires were collected in the southeastern and southwestern US and burned in a series of 71 fires at the US Forest Service Fire Sciences Laboratory in Missoula, Montana. The particulate matter (PM2.5) emissions were measured by gravimetric filter sampling with subsequent analysis for elemental carbon (EC), organic carbon (OC), and 38 elements. The trace gas emissions were measured by an open-path Fourier transform infrared (OP-FTIR) spectrometer, proton-transfer-reaction mass spectrometry (PTRMS), proton-transfer ion-trap mass spectrometry (PIT-MS), negative-ion proton-transfer chemical-ionization mass spectrometry (NI-PT-CIMS), and gas chromatography with MS detection (GC-MS). 204 trace gas species (mostly non-methane organic compounds (NMOC)) were identified and quantified with the above instruments. Many of the 182 species quantified by the GC-MS have rarely, if ever, been measured in smoke before. An additional 153 significant peaks in the unit mass resolution mass spectra were quantified, but either could not be identified or most of the signal at that molecular mass was unaccounted for by identifiable species. In a second, "field" phase of this program, airborne and ground-based measurements were made of the emissions from prescribed fires that were mostly located in the same land management units where the fuels for the lab fires were collected. A broad variety, but smaller number of species (21 trace gas species and PM2.5) was measured on 14 fires in chaparral and oak savanna in the southwestern US, as well as pine forest understory in the southeastern US and Sierra Nevada mountains of California. The field measurements of emission factors (EF) are useful both for modeling and to examine the representativeness of our lab fire EF. The lab EF/field EF ratio for the pine understory fuels was not statistically different from one, on average. However, our lab EF for "smoldering compounds" emitted from the semiarid shrubland fuels should likely be increased by a factor of similar to 2.7 to better represent field fires. Based on the lab/field comparison, we present emission factors for 357 pyrogenic species (including unidentified species) for 4 broad fuel types: pine understory, semiarid shrublands, coniferous canopy, and organic soil. To our knowledge this is the most comprehensive measurement of biomass burning emissions to date and it should enable improved representation of smoke composition in atmospheric models. The results support a recent estimate of global NMOC emissions from biomass burning that is much higher than widely used estimates and they provide important insights into the nature of smoke. 31-72% of the mass of gas-phase NMOC species was attributed to species that we could not identify. These unidentified species are not represented in most models, but some provision should be made for the fact that they will react in the atmosphere. In addition, the total mass of gas-phase NMOC divided by the mass of co-emitted PM2.5 averaged about three (range similar to 2.0-8.7). About 35-64% of the NMOC were likely semivolatile or of intermediate volatility. Thus, the gas-phase NMOC represent a large reservoir of potential precursors for secondary formation of ozone and organic aerosol. For the single lab fire in organic soil about 28% of the emitted carbon was present as gas-phase NMOC and similar to 72% of the mass of these NMOC was unidentified, highlighting the need to learn more about the emissions from smoldering organic soils. The mass ratio of total NMOC to "NOx as NO" ranged from 11 to 267, indicating that NOx-limited O-3 production would be common in evolving biomass burning plumes. The fuel consumption per unit area was 7.0 +/- 2.3 Mg ha(-1) and 7.7 +/- 3.7 Mg ha(-1) for pine-understory and semiarid shrubland prescribed fires, respectively. C1 [Yokelson, R. J.; Burling, I.

Once inside this secondary host, polydnaviruses cause a wide variety of negative effects that ultimately ensure the survival of the parasitoid larvae. Because of their unusual life strategy and genetic features, it had been difficult to fully characterise polydnaviruses in terms of evolutionary history, replication cycle and functions in the host that might normally be well characterised for more conventional viruses. Recently, our understanding of polydnavirus evolutionary origins, gene content, genome organisation and functions in parasitism has greatly increased. Key findings are summarised in this review with emphasis on evolution of polydnavirus genes and genomes, their functional roles in insect pathology and their potential applications in insect biological control and biotechnology.

However, the impact of excess FA intake, particularly during pregnancy, requires investigation. In a recent study, we reported that a diet supplemented with 20-fold higher FA than the recommended intake for rodents had adverse effects on embryonic mouse development at embryonic days (E)10.5 and 14.5. In this report, we examined developmental outcomes in E14.5 embryos after administering a diet supplemented with 10-fold higher FA than recommended to pregnant mice with and without a mild deficiency of methylenetetrahydrofolate reductase (MTHFR). METHODS Pregnant mice with or without a deficiency in MTHFR were fed a control diet (recommended FA intake of 2 mg/kg diet for rodents) or an FA-supplemented diet (FASD; 10-fold higher than the recommended intake [20 mg/kg diet]). At E14.5, mice were examined for embryonic loss and growth retardation, and hearts were assessed for defects and for ventricular wall thickness. RESULTS Maternal FA supplementation was associated with embryonic loss, embryonic delays, a higher incidence of ventricular septal defects, and thinner left and right ventricular walls, compared to mothers fed control diet. CONCLUSIONS Our work suggests that even moderately high levels of FA supplementation may adversely affect fetal mouse development. Additional studies are warranted to evaluate the impact of high folate intake in pregnant women. Birth Defects Research (Part A), 2013. (c) 2012 Wiley Periodicals, Inc.

Genetic modification could be used to create cultivars capable of producing more uniform or focused and novel protein compositions targeted to nonfood uses. These lines could serve as expression systems for specific high-molecular-weight (HMW) protein poly. mers and would be new crops leading to more diverse agricultural opportunities. However, fundamental changes to the molecular architecture in such wheat seeds could also result in separation and processing issues, such that conventional methods of protein enrichment may need modification or even reinvention. Enriched gluten protein fractions were prepared from Bobwhite lines modified to overproduce HMW glutenin subunits Dx5 and/or Dy10. These lines serve as experimental models to test various approaches that may be taken for protein polymer enrichment. However, conventional wheat gluten enrichment based on the glutomatic as a small model of industrial methods was incapable of producing enrichment for any of the tested meal or flour, including that from the non-transformed parent Bobwhite. Mixing in the mixograph or farinograph failed to produce standard patterns for whole kernel meal and straight-run flour, and the normal cohesiveness of dough expected from these devices was not observed. Microscopy of stained dough samples revealed severely limited formation of normal protein networks, a capability crucial to conventional separation technology. Particle size analysis of whole kernel meal revealed a higher resistance to milling for the altered lines. Higher drying rates, lower farinograph moisture absorption, and increased thermal transition temperatures were observed. These data suggested that the native architecture of these new forms was more tightly constructed with reduced capacity for alteration by hydration and input of mechanical energy. An alternative enrichment method featuring solvation in SDS and precipitation in acetone produced coagulated (Bobwhite) or partially coagulated protein (transgenic lines producing Dx5 or Dy10) enriched to 78-85% protein with high yield.

In particular, these altered lines were characterized by poor mixing properties, the formation of mixtures in water that could not be separated by conventional mechanical methods, reduced water absorption, unique milling properties, and severely limited development of microscopic fibrils. These attributes suggested inherent organizational differences at submicroscopic and molecular levels among the various lines. Therefore, proteins were fractionated from whole meals using 70% ethanol to elucidate solubility characteristics and compositions and to infer structural properties. Capillary zone electrophoresis and one-and two-dimensional SDS-PAGE (2DE) revealed striking differences in the protein composition and solubility among these new lines and the Bobwhite from which they were derived. Generally, Bobwhite yielded soluble protein that included not only what would be considered as classical gliadins but also some of each of the HMW-GS as monomer's or polymers with low degrees of polymerization, whereas the genetically altered lines produced far less total soluble protein and very limited amounts of HMW-GS. In the extreme, high, levels of expression of Dx5 subunit not only led to reduced solubility of the HMW-GS but also limited the solubility of the many other proteins that are normally soluble. In addition, a matrix association factor similar to the classical separation factor of analytical chemistry and chemical engineering was introduced and applied to 2DE data for insoluble and soluble protein to summarize and index relative involvement of specifically enhanced proteins in the insoluble gluten matrix after equilibration with ethanol. The highest relative association was determined for the HMW-GS lines enriched in Dx5 or Dy10 protein and the lowest for Bobwhite. Greater association was indicated for Dx5 than for Dy10 protein in these lines. The value of the association factor was likely influenced by differences in glutamine-to-cysteine ratios and differences in altered glutenin chain configurations stemming from high levels of expression of a single or limited number of HMW-GS.

TI Influence of Cooking Formulation on Flavor and Hydrophilic Oxygen Radical Absorption Capacity Values of Whole Grain Colored Rice SO CEREAL CHEMISTRY LA English DT Article ID ANTIOXIDANT CAPACITY; LIPID OXIDATION; TASTE; SUPPRESSION; BITTERNESS; MIXTURES; BRAN AB Whole grain rice is rich in healthful polyphenolic compounds that can impart undesirable flavors. Rice is typically prepared with water and sometimes salt, oil, or both, which can influence flavor. This research examines the influences of cooking whole grain rice with salt, oil, or both on flavor and antioxidant capacity. Nine commercial rice samples (three brown, three red, and three black or purple) were cooked with water only, added salt (0.5%), oil (1.575% v/w), or salt with oil (same concentrations). Flavor was measured with descriptive flavor analysis, and antioxidant capacity was measured by the hydrophilic oxygen radical absorption capacity (H-ORAC) method. The addition of salt and salt with oil significantly reduced bitter, water-like/metallic, and astringent flavors, whereas corn/popcorn/buttery flavor was increased. Cooking formulation significantly affected more flavor attributes in black/purple and brown bran samples than in the red bran samples. Salt, oil, or both can be added to rice at cooking to modify taste with only slight effects on antioxidant benefits. Bran color significantly influences many flavor attributes as well as impacting H-ORAC values.

In an effort to develop safe practices for using TIF, a large field study was conducted in the San Joaquin Valley of California. Comprehensive data on emissions (measured with dynamic flux chambers), fate, and transport of 1,3-dichloropropene and chloropicrin were collected in a 3.3 ha field fumigated with Pic-Clor 60 via broadcast shank application. Low emission flux (below 15 mu g m(-2) s(-1)) was observed from the tarped field throughout the tarp-covering period of 16 days with total emission loss of <8% of total applied for both chemicals. Although substantially higher flux was measured at tarp edges (up to 440 mu g m(-2) s(-1)), the flux was reduced to below 0.5 mu g m(-2) s(-1) beyond 2 m of tarp edge where total mass loss was estimated to be <= 1% of total applied to the field. Emission flux increased following tarp-cutting, but was much lower compared to 5 or 6 d tarp-covering periods determined in other fields. This study demonstrated the ability of TIF to significantly reduce fumigant emissions with supporting data on fumigant movement in soil. Proper management on use of the tarp, such as extending tarp-covering period, can reduce negative impact on the environment and help maintain the beneficial use of soil fumigants for agricultural productions.

TI Efficacy of a multi micronutrient-fortified drink in improving iron and micronutrient status among schoolchildren with low iron stores in India: a randomised, double-masked placebo-controlled trial SO EUROPEAN JOURNAL OF CLINICAL NUTRITION LA English DT Article DE fortification; micronutrients; children; iron deficiency; iron deficiency anemia; anemia ID PRIMARY-SCHOOL CHILDREN; NUTRITIONAL-STATUS; VITAMIN-A; BODY IRON; ANEMIA; ABSORPTION; RIBOFLAVIN; HEMOGLOBIN; DEFICIENCY; THAILAND AB BACKGROUND/OBJECTIVES: A multiple micronutrient-fortified drink could be an effective strategy to combating micronutrient deficiencies in school going children. To assess the efficacy of a multiple micronutrient-fortified drink in reducing iron deficiency (ID), ID anemia (IDA), anemia and improving micronutrient status among schoolchildren with low iron stores. The study employed a school-based, randomized, double-blind, placebo-controlled design. SUBJECTS/METHODS: Schoolchildren with low serum ferritin (SF <20 mu g/l) (n=246), aged 6-12 years were randomly assigned to receive either a multi-micronutrient fortified or an unfortified identical control drink. The drinks were provided 6 days/week for 8 weeks. Anthropometric and biochemical assessments were taken at baseline and endline. RESULTS: Study groups at baseline were comparable, and compliance to the intervention was similar. The overall prevalence of ID, IDA and anemia was 64%, 19% and 24%, respectively. The prevalence of ID, IDA, vitamin C and vitamin B-12 deficiencies significantly reduced by 42%, 18%, 21% and 5%, respectively, in the intervention arm (P<0.01) as compared with the control arm at the end of the study. Similarly, the concentration of hemoglobin, SF, vitamin A, vitamin B-12, vitamin C and body iron stores were significantly higher in the intervention arm in comparison to the control arm (P<0.001). Red cell folate levels also improved significantly in the intervention arm (P=0.04), however, serum zinc status did not change in either of the study arms. Children who had received the fortified drink had significantly lower odds of being ID (0.15; 95% confidence interval (CO: 0.09-0.27), IDA (0.14; 95% CI: 0.04-0.52), vitamin B-12 deficient (0.36; 95% CI: 0.18-0.73) and vitamin C deficient (0.24; 95% CI: 0.13-0.46), after adjusting for baseline age, gender and weight. CONCLUSIONS: The multi micronutrient-fortified drink was efficacious in reducing the prevalence of ID, IDA, vitamin C and vitamin B-12 deficiency and improved micronutrient status in schoolchildren.

TI Relationships among genera of the Saccharomycotina (Ascomycota) from multigene phylogenetic analysis of type species SO FEMS YEAST RESEARCH LA English DT Article DE yeast phylogeny; ascomycete yeasts; Saccharomycotina ID ASCOMYCETOUS YEASTS; GEN. NOV.; SEQUENCE-ANALYSIS; PROPOSAL; FUNGI; 18S; EVOLUTION AB Relationships among ascomycetous yeast genera (subphylum Saccharomycotina, phylum Ascomycota) have been uncertain. In the present study, type species of 70 currently recognized genera are compared from divergence in the nearly entire nuclear gene sequences for large subunit rRNA, small subunit (SSU) rRNA, translation elongation factor-1a, and RNA polymerase II, subunits 1 (RPB1) and 2 (RPB2). The analysis substantiates earlier proposals that all known ascomycetous yeast genera now assigned to the Saccharomycotina represent a single clade. Maximum likelihood analysis resolved the taxa into eight large multigenus clades and four-one- and two-genus clades. Maximum parsimony and neighbor-joining analyses gave similar results. Genera of the family Saccharomycetaceae remain as one large clade as previously demonstrated, to which the genus Cyniclomyces is now assigned. Pichia, Saturnispora, Kregervanrija, Dekkera, Ogataea and Ambrosiozyma are members of a single large clade, which is separate from the clade that includes Barnettozyma, Cyberlindnera, Phaffomyces, Starmera and Wickerhamomyces. Other clades include Kodamaea, Metschnikowia, Debaryomyces, Cephaloascus and related genera, which are separate from the clade that includes Zygoascus, Trichomonascus, Yarrowia and others. This study once again demonstrates that there is limited congruence between a system of classification based on phenotype and a system determined from DNA sequences.

TI Survival of Escherichia coli O157:H7 Transformed with Either the pAK1-lux or pXEN-13 Plasmids in In Vitro Bovine Ruminal and Fecal Microbial Fermentations SO FOODBORNE PATHOGENS AND DISEASE LA English DT Article ID BIOLUMINESCENT REPORTER; SALMONELLA-TYPHIMURIUM; GASTROINTESTINAL-TRACT; GENE-EXPRESSION; REAL-TIME; O157-H7; BEEF; INTERVENTIONS; INFECTION; PATHOGENS AB The use of luminescent plasmids in bacteria may serve as a viable model for the real-time validation of various pre-harvest interventions on the colonization or shedding patterns of Escherichia coli O157:H7 within cattle. The objective of this study was to determine if the growth characteristics of E. coli O157:H7 in mixed ruminal and fecal microbial fluid cultures would be altered when transformed with one of the two luminescent plasmids: pAK1-lux (PAK) or pXEN-13 (XEN). Transformants harboring the luminescent plasmids were compared to the non-transformed parental strain (wild type [WT]) after incubating in mixed ruminal or fecal microbial fluid media for 6 h in triplicate (n = 3). The transformants and WT exhibited similar growth rates. Within mixed ruminal microbial fluid fermentations and mixed fecal microbial fluid, all transformants grew similarly (p = 0.28) through the 6-h study. The reflective light unit (RLU; photons/pixel per second) photonic emissions of each plasmid within ruminal fluid differed at 0 h (p = 0.002) and 2 h (p = 0.02) and within fecal fluid at 0 h (p = 0.009) and 2 h (p = 0.04). The RLU remained the same within rumen fluid at 4 h (p = 0.22) and 6 h (p = 0.80) and within fecal fluid at 4 h (p = 0.06) and 6 h (p = 0.29). Growth of E. coli O157:H7 transformed with the bioluminescent plasmids was not altered in comparison to the WT, suggesting that both plasmids may serve as useful models for in vivo studies.

However, information on the effect of storage temperatures on injured bacterial populations was not addressed. In this study, the effect of storage temperatures on the survival and recovery of thermal death time (TDT) disks and extrusion injured E. coli populations in CP and WPP was investigated. CP and WPP inoculated with E. coli bacteria at 7.8 log(10) CFU/g were conveyed separately into the extruder with a series 6300 digital type T-35 twin screw volumetric feeder set at a speed of 600 rpm and extruded at 35 degrees C, 55 degrees C, 75 degrees C, and 95 degrees C, or thermally treated with TDT disks submerged into water bath set at 35 degrees C, 55 degrees C, 75 degrees C, and 95 degrees C for 120 s. Populations of surviving bacteria including injured cells in all treated samples were determined immediately and every day for 5 days, and up to 10 days for untreated samples during storage at 5 degrees C, 10 degrees C, and 23 degrees C. TDT disks treatment at 35 degrees C and 55 degrees C did not cause significant changes in the population of the surviving bacteria including injured populations. Extrusion treatment at 35 degrees C and 55 degrees C led to significant (p < 0.05) reduction of E. coli populations in WPP as opposed to CP. The injured populations among the surviving E. coli cells in CP and WPP extruded at all temperatures tested were inactivated during storage. Population of E. coli inactivated in samples extruded at 75 degrees C was significantly (p < 0.05) different than 55 degrees C during storage. Percent injured population could not be determined in samples extruded at 95 degrees C due to absence of colony forming units on the agar plates. The results of this study showed that further inactivation of the injured populations occurred during storage at 5 degrees C for 5 days suggesting the need for immediate storage of 75 degrees C extruded CP and WPP at 5 degrees C for at least 24 h to enhance their microbial safety.

In an effort to identify natural antimicrobial agents as fresh produce-wash, the effect of essential oils in reducing enteric pathogens on iceberg and romaine lettuce was investigated. Lettuce pieces were inoculated with a five-strain cocktail of Escherichia coli O157:H7 or Salmonella enterica (5 log CFU/g) and then immersed in a treatment solution containing 5ppm free chlorine, cinnamaldehyde, or Sporan (R) (800 and 1000 ppm) alone or in combination with 200 ppm acetic acid (20%) for 1 min. Treated leaves were spin-dried and stored at 4 degrees C. Samples were taken to determine the surviving populations of E. coli O157:H7, Salmonella, total coliforms, mesophilic and psychrotrophic bacteria, and yeasts and molds during the 14-day storage period. The effect of treatments on lettuce color and texture was also determined. Cinnamaldehyde-Tween (800 ppm, 800T) reduced E. coli O157:H7 by 2.89 log CFU/g (p < 0.05) on iceberg lettuce at day 0; Sporan (R)-acetic acid (1000SV) reduced E. coli O157:H7 and Salmonella on iceberg and romaine lettuce by 2.68 and 1.56 log CFU/g (p < 0.05), respectively, at day 0. The effect of essential oils was comparable to that of 5ppm free chlorine in reducing E. coli O157:H7 and Salmonella populations on iceberg and romaine lettuce throughout the storage time. The natural microbiota on treated lettuce leaves increased during the storage time, but remained similar (p > 0.05) to those treated with chlorine and control (water). The texture and the color of iceberg and romaine lettuce treated with essential oils were not different from the control lettuce after 14 days of storage. This study demonstrates the potential of Sporan (R) and cinnamaldehyde as effective lettuce washes that do not affect lettuce color and texture. C1 [Yossa, Nadine; Lo, Y.

TI Response of ponderosa pine plantations to competing vegetation control in Northern California, USA: a meta-analysis SO FORESTRY LA English DT Article ID FOREST VEGETATION; MANAGEMENT; PRODUCTIVITY; SITES AB A meta-analysis was performed to determine response of stand basal area growth to competing vegetation control (CVC) in ponderosa pine (Pinus ponderosa) plantations grown at 29 sites across northern California. These studies were installed during the last 50 years on site indices from 11 to 35 m at 50 years and often included other treatments besides CVC. Our analyses showed, with considerable certainty, that the magnitude of the CVC effect on overall basal area increase was 80% (40%-105%). The 40% increase occurred 5 years and the 105% increase occurred 10 years after the treatment was applied. A 67% to 91% increase was found 15 to 30 years after CVC. Additional treatments such as fertilization and high stand density accelerated the CVC effect. The trends of the CVC effect not only varied with stand developmental stages but also differed where CVC treatments were applied to seedlings or to older plantations. Results suggest that productivity response to vegetation control increases during the stand initiation stage and peaks when stands are in the stem exclusion stage. Thus, the magnitude of CVC effect depends on when it is applied relative to the stage of stand development. Any factors that increase stand development will accelerate this process. Therefore, to capture early growth gains, stands must be thinned soon after the onset of inter-tree competition. Timing depends on site productivity and previous silvicultural treatments.

SO FORESTRY LA English DT Article ID ORGANIC-MATTER REMOVAL; PONDEROSA PINE; MINERAL SOIL; COMPETING-VEGETATION; NORTHERN CALIFORNIA; FOREST MANAGEMENT; LOGGING-DEBRIS; UNITED-STATES; PRODUCTIVITY; PLANTATIONS AB Forests and the soils beneath them are Earths largest terrestrial sinks for atmospheric carbon (C) and healthy forests provide a partial check against atmospheric rises in CO2. Consequently, there is global interest in crediting forest managers who enhance C retention. Interest centres on C acquisition and storage in trees. Less is directed to understorey management practices that affect early forest development. Even less is paid to the largest ecosystem reservoir of all the mineral soil. Understorey vegetation control is a common management practice to boost stand growth, but the consequence of this on ecosystem C storage is poorly understood. We addressed this by pooling data from five independent groups of long-term studies in the western US. Understorey control increased overstorey biomass universally, but C contents of the forest floor and top 30 cm of mineral soil largely were unaffected. Net soil C increment averaged 1.3 Mg C ha(1) year(1) in the first decade. We conclude that soil C storage is not affected adversely by vegetation management in forests under a Mediterranean climate. However, understorey shrubs can profoundly affect stand susceptibility to wildfire. We propose that C accounting systems be strengthened by assessing understorey management practices relative to wildfire risk.

TI Distance-limited perpendicular distance sampling for coarse woody debris: theory and field results SO FORESTRY LA English DT Article ID POINT RELASCOPE; LINE-INTERSECT; AREA; ECOLOGY; DEAD AB Coarse woody debris (CWD) has been identified as an important component in many forest ecosystem processes. Perpendicular distance sampling (PDS) is one of the several efficient new methods that have been proposed for CWD inventory. One drawback of PDS is that the maximum search distance can be very large, especially if CWD diameters are large or the volume factor chosen is small. Here, we propose a modified method, which we call distance-limited PDS, that addresses this limitation. We describe the field procedures, develop new a new estimator, and provide a proof of unbiasedness of that estimator. The new method is compared with line intersect sampling (LIS) and PDS in a field trial in the northeastern United States. The results of the field trial show that this new method requires as little as 1/10 the sampling effort of LIS in order to achieve comparable variance of the estimates.

TI A comprehensive comparison of perpendicular distance sampling methods for sampling downed coarse woody debris SO FORESTRY LA English DT Review ID LINE INTERSECT; ALTERNATIVE METHOD; VOLUME; AREA AB Many new methods for sampling down coarse woody debris have been proposed in the last dozen or so years. One of the most promising in terms of field application, perpendicular distance sampling (PDS), has several variants that have been progressively introduced in the literature. In this study, we provide an overview of the different PDS variants and comprehensive comparison of their associated estimator performance. Additionally, two new variants and their estimators are introduced to the existing pool. Simulations are used to determine the efficiency of competing protocols and associated estimators. The simulation results corroborate the theoretical unbiasedness of the estimators for PDS in all forms. In addition, while there is some difference in variance among the protocols, the overall difference is small, and depends on the attribute to be estimated. Therefore, the choice of which PDS variant to use in field applications will depend on the field conditions and attributes to be estimated.

However, the relationship between linkage groups and individual chromosomes of sunflower remains unknown and has considerable relevance for the sunflower research community. Recently, a set of linkage group-specific bacterial /binary bacterial artificial chromosome (BAC/BIBAC) clones was identified from two complementary BAC and BIBAC libraries constructed for cultivated sunflower cv. HA89. In the present study, we used these linkage group-specific clones (similar to 100 kb in size) as probes to in situ hybridize to HA89 mitotic chromosomes at metaphase using the BAC- fluorescence in situ hybridization (FISH) technique. Because a characteristic of the sunflower genome is the abundance of repetitive DNA sequences, a high ratio of blocking DNA to probe DNA was applied to hybridization reactions to minimize the background noise. As a result, all sunflower chromosomes were anchored by one or two BAC/BIBAC clones with specific FISH signals. FISH analysis based on tandem repetitive sequences, such as rRNA genes, has been previously reported; however, the BAC- FISH technique developed here using restriction fragment length polymorphism (RFLP) -derived BAC/BIBAC clones as probes to apply genome-wide analysis is new for sunflower. As chromosome-specific cytogenetic markers, the selected BAC/BIBAC clones that encompass the 17 linkage groups provide a valuable tool for identifying sunflower cytogenetic stocks (such as trisomics) and tracking alien chromosomes in interspecific crosses. This work also demonstrates the potential of using a large-insert DNA library for the development of molecular cytogenetic resources.

Pathogenicity by this fungus is attributed to the production of host-selective toxins ( HST), which are recognized by their host in a genotype-specific manner. To better understand the mechanisms that have led to the increase in disease incidence related to this pathogen, we sequenced the genomes of three P. tritici-repentis isolates. A pathogenic isolate that produces two known HSTs was used to assemble a reference nuclear genome of approximately 40 Mb composed of 11 chromosomes that encode 12,141 predicted genes. Comparison of the reference genome with those of a pathogenic isolate that produces a third HST, and a nonpathogenic isolate, showed the nonpathogen genome to be more diverged than those of the two pathogens. Examination of gene-coding regions has provided candidate pathogen-specific proteins and revealed gene families that may play a role in a necrotrophic lifestyle. Analysis of transposable elements suggests that their presence in the genome of pathogenic isolates contributes to the creation of novel genes, effector diversification, possible horizontal gene transfer events, identified copy number variation, and the first example of transduplication by DNA transposable elements in fungi. Overall, comparative analysis of these genomes provides evidence that pathogenicity in this species arose through an influx of transposable elements, which created a genetically flexible landscape that can easily respond to environmental changes.

MOENCH; GRASSES; GRAINS; QTLS; MAP; DOMESTICATION; CHROMOSOMES AB We describe a recombinant inbred line (RIL) population of 161 F5 genotypes for the widest euploid cross that can be made to cultivated sorghum (Sorghum bicolor) using conventional techniques, S. bicolor x Sorghum propinquum, that segregates for many traits related to plant architecture, growth and development, reproduction, and life history. The genetic map of the S. bicolor x S. propinquum RILs contains 141 loci on 10 linkage groups collectively spanning 773.1 cM. Although the genetic map has DNA marker density well-suited to quantitative trait loci mapping and samples most of the genome, our previous observations that sorghum pericentromeric heterochromatin is recalcitrant to recombination is highlighted by the finding that the vast majority of recombination in sorghum is concentrated in small regions of euchromatin that are distal to most chromosomes. The advancement of the RIL population in an environment to which the S. bicolor parent was well adapted (indeed bred for) but the S. propinquum parent was not largely eliminated an allele for short-day flowering that confounded many other traits, for example, permitting us to map new quantitative trait loci for flowering that previously eluded detection. Additional recombination that has accrued in the development of this RIL population also may have improved resolution of apices of heterozygote excess, accounting for their greater abundance in the F5 than the F2 generation. The S. bicolor x S. propinquum RIL population offers advantages over early-generation populations that will shed new light on genetic, environmental, and physiological/biochemical factors that regulate plant growth and development.

TI Soil sorptivity enhancement with crop residue accumulation in semiarid dryland no-till agroecosystems SO GEODERMA LA English DT Article DE Soil sorptivity; Crop residue; Soil physical properties ID PHYSICAL-PROPERTIES; MANAGEMENT; CARBON; REMOVAL AB Water capture and precipitation use efficiency are of great importance in dryland cropping systems because the world's dependence on food produced in dryland areas continues to increase. Growing season evapotranspiration potential greatly exceeds growing season precipitation rates in dryland areas, creating a water deficit for crops. Management practices that positively impact soil physical properties increase the potential for soils to capture water. One way to assess the ability of soils to capture water is through the measurement of sorptivity. Sorptivity is defined as the cumulative infiltration proportionality constant and is governed by surface soil physical properties such as texture, degree of aggregation and aggregate stability. A study was conducted to determine how crop residue accumulation after 12 years of no-till management affects surface soil sorptivity under semi-arid dryland conditions and how sorptivity is related to surface soil physical properties known to be related to crop residue accumulation. Surface soil sorptivity, bulk density, porosity (total and effective) and aggregation measurements were made across cropping systems and soil positions representing a wide gradient of crop residue accumulation at 3 sites in eastern Colorado. Results show that increasing crop residue accumulation will have the indirect effect of increased sorptivity via improvements in soil aggregation, bulk density, and porosity that are conducive to water infiltration. Management practices that result in greater amounts of crop residue returned to the soil system lead to beneficial soil physical properties that increase water sorptivity, greatly reducing the potential for runoff and erosion, and thereby increase the precipitation use efficiency of the system.

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

TI WRF-Fire: Coupled Weather-Wildland Fire Modeling with the Weather Research and Forecasting Model SO JOURNAL OF APPLIED METEOROLOGY AND CLIMATOLOGY LA English DT Article ID DISCRETE FUEL-ELEMENTS; WIND-AIDED FIRESPREAD; GRASS FIRES; SPREAD; DYNAMICS; BEHAVIOR; SIMULATIONS; FRONTS; GROWTH; ARRAYS AB A wildland fire-behavior module, named WRF-Fire, was integrated into the Weather Research and Forecasting (WRF) public domain numerical weather prediction model. The fire module is a surface fire-behavior model that is two-way coupled with the atmospheric model. Near-surface winds from the atmospheric model are interpolated to a finer fire grid and are used, with fuel properties and local terrain gradients, to determine the fire's spread rate and direction. Fuel consumption releases sensible and latent heat fluxes into the atmospheric model's lowest layers, driving boundary layer circulations. The atmospheric model, configured in turbulence-resolving large-eddy-simulation mode, was used to explore the sensitivity of simulated fire characteristics such as perimeter shape, fire intensity, and spread rate to external factors known to influence fires, such as fuel characteristics and wind speed, and to explain how these external parameters affect the overall fire properties. Through the use of theoretical environmental vertical profiles, a suite of experiments using conditions typical of the daytime convective boundary layer was conducted in which these external parameters were varied around a control experiment. Results showed that simulated fires evolved into the expected bowed shape because of fire-atmosphere feedbacks that control airflow in and near fires. The coupled model reproduced expected differences in fire shapes and heading-region fire intensity among grass, shrub, and forest-litter fuel types; reproduced the expected narrow, rapid spread in higher wind speeds; and reproduced the moderate inhibition of fire spread in higher fuel moistures. The effects of fuel load were more complex: higher fuel loads increased the heat flux and fire-plume strength and thus the inferred fire effects but had limited impact on spread rate.

Previous house fly surveys have detected the pathogen Staphylococcus aureus Rosenbach 1884, which causes cutaneous and septic infections in mammals, and enterotoxic food poisoning. We assessed the fate of GFP-expressing S. aureus (GFP-S. aureus) in the house fly alimentary canal with microscopy and by culture of whole flies and excreta. Furthermore, the concurrent expression of the antimicrobial peptide gene defensin was measured in the crop, proventriculus, midgut, and fat body. As soon as 4 h postingestion (PI), GFP-S. aureus were visualized as cocci or diplococci in the hindgut and rectum of flies fed approximate to 10(5) colony forming units. Bacteria persisted up to 6 h PI but significantly decreased. Excretion of viable GFP-S. aureus peaked at 2 h PI and, although significantly less, continued up to 4 h PI. defensin was highly upregulated locally in the alimentary canal and systemically in fat body at 2, 4, and 6 h PI making this study the first to report, to our knowledge, an epithelial and systemic response to a bacterium with lysine-type peptidoglycan in flies exposed via feeding. While flies harbored S. aureus for up to 6 h PI, the highest probability of vectoring biologically relevant amounts of bacteria occurred 0-2 h PI. The combined effects of excretion, digestion and antimicrobial effectors likely contribute to loss of ingested bacteria. Nonetheless, house flies are relevant vectors for S. aureus up to 2 h PI and environmental reservoirs up to 6 h PI.

TI Impacts of exotic mangroves and chemical eradication of mangroves on tide pool fish assemblages SO MARINE ECOLOGY PROGRESS SERIES LA English DT Article DE Rhizophora mangle; Invasive species; Non-native species; Nursery habitat; Kuhlia xenura; Poecilia; Hawaii; Pacific Island ID PAMLICO SOUND; HABITAT; ECOSYSTEM; HAWAII; PHRAGMITES; PATTERNS; BIODIVERSITY; MECHANISMS; RHIZOPHORA; VEGETATION AB Fish were sampled from tide pools in Hawaii to determine how exotic mangroves Rhizophora mangle and the use of herbicides to chemically eradicate them are impacting tide pool fish assemblages. Ecological parameters were compared among mangrove-invaded, native vegetated, and non-vegetated tide pools before and after mangroves had been chemically eradicated. Native fish densities were higher than exotic fish densities in all treatments, were dominated by flagtails Kuhlia xenura, did not differ among treatments, and 1 yr after herbicidial eradication of mangroves, were greater than or equal to pre-control densities. Exotic fish densities did not differ between mangrove and native vegetated tide pools, were dominated by mollies Poecilia sp., were significantly lower in non-vegetated vs. vegetated pools, and did not differ before and after mangrove eradication. Significantly smaller native flagtails and exotic mollies were present in mangrove tide pools than in all other treatments. Our data suggests that exotic mangroves in Hawaii are not having an adverse effect on native fish assemblages in tide pools, and may actually provide nursery habitat for native and exotic fish. Furthermore, the presence of vegetation and not its origin may be more influential on exotic fish assemblages. Finally, our data suggests that if chemical eradication of mangroves negatively affected tide pool fish assemblages, those effects are short-lived. Future studies should attempt to quantify the ecological value of native versus exotic vegetation in supporting native (or exotic) fish assemblages.

Merrill) were exposed to radiation doses up to 3.0 kGy. The irradiated and non-irradiated seeds were germinated, and then germination rate, sprouts length, vitamin C content, antioxidants and visual and olfactory quality were determined after irradiation. Results indicated that there was no significant difference in the germination rate and sprouts length between the control and 0.3 kGy treated soybeans, however, the reductions in sprouts length of the 1.0 kGy and 3.0 kGy treated samples were quite significant with reductions of 20.4% and 58.8%, respectively. Irradiated sprouts had similar visual and olfactory quality as the non-irradiated one. Therefore, irradiation of seeds alone would have limited value in terms of commercial use due to reduced germination and length of sprouts. However, irradiation of sprouts at doses up to 3.0 kGy was feasible to enhance microbial safety of sprouts. (C) 2012 Elsevier Ltd. All rights reserved.

Re-sequencing of a virulent strain of NCTC11168 identified 41 SNPs or indels involving 20 genes, four intergenic regions and three pseudogenes. The genes include six motility genes, two chemotaxis genes, three hypothetical genes and a capsule biosynthesis gene, which might have a critical role in C. jejuni virulence. Additionally, we found an insertion in both Cj0676 and Cj1470c, pseudogenes in avirulent NCTC11168, but functional proteins in virulent NCTC11168. (C) 2012 Institut Pasteur.

Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to recommend appropriate water application strategies. To better understand moisture variation within a wet deck, time domain reflectometry (TDR) was used to monitor the moisture variation of 30 southern pine logs over an 11-week period for a wet deck at the International Paper McBean woodyard. Three 125 mm long TDR probes were inserted into each log (before the deck was built) at 3, 4.5, and 7.5 m from the butt. The position of each log within the stack was also recorded. Mixed-effects analysis of variance (ANOVA) was used to examine moisture variation over the study period. Moisture content varied within the log, while position within the stack was generally not significant. The performance of the TDR probes was consistent throughout the study, indicating that they would be suitable for long term (e.g., 12 months) monitoring.

Scientists have developed resistance-testing protocols for numerous herbicides and weed species. Growers need immediate answers and scientists are faced with the daunting task of testing an increasingly large number of samples across a variety of species and herbicides. Quick tests have been, and continue to be, developed to address this need, although classical tests are still the norm. Newer methods involve molecular techniques. Whereas the classical whole-plant assay tests for resistance regardless of the mechanism, many quick tests are limited by specificity to an herbicide, mode of action, or mechanism of resistance. Advancing knowledge in weed biology and genomics allows for refinements in sampling and testing protocols. Thus, approaches in resistance testing continue to diversify, which can confound the less experienced. We aim to help weed science practitioners resolve questions pertaining to the testing of herbicide resistance; starting. with field surveys and sampling methods, herbicide screening methods, data analysis, and, finally, interpretation. More specifically, this article discusses approaches for sampling plants for resistance confirmation assays, provides brief overviews on the biological and statistical basis for designing and analyzing dose response tests, and discusses alternative procedures for rapid resistance confirmation, including molecular-based assays. Resistance confirmation procedures often need to be slightly modified to suit a specific situation; thus, the general requirements as well as pros and cons of quick assays and DNA-based assays are contrasted. Ultimately, weed resistance testing research, as well as resistance management decisions arising from research, needs to be practical, feasible, and grounded in science-based methods.

However, unexpected interactions may develop, especially for herbicides not generally used in tank-mixtures. The objectives of this study were to evaluate weed control and determine herbicide interactions and fluorescence responses with combinations of glyphosate and glufosinate on selected weeds prevalent in Michigan cropping systems. Field studies to determine herbicide interactions resulted in synergism only at 0.84 kg ae ha(-1) of glyphosate and 0.47 kg ai ha(-1) glufosinate in 2008. Early synergism (7 d after treatment [DAT]) was observed in the field at several combined rates for common lambsquarters and velvetleaf in 2009, and in the greenhouse for giant foxtail. Differences between years were perhaps due to the effect of environmental conditions on herbicide absorption and translocation. Antagonism was observed in the field in 2009 for velvetleaf, common lambsquarters, and giant foxtail especially at 840 g ae ha(-1) glyphosate and 118 g ai ha(-1) glufosinate, 28 DAT. Antagonism was also observed in the greenhouse for giant foxtail and Canada thistle, 28 DAT. Fluorescence measurements on Canada thistle in the greenhouse showed that glufosinate and glufosinate plus glyphosate acted rapidly to quench electron transport of photosystem II (PS II) system of photosynthesis, and the fluorescence characteristics of the glyphosate and glufosinate combinations were indistinguishable from glufosinate alone.

Laboratory studies were conducted to determine if absorption, translocation, and metabolism of aminocyclopyrachlor in field bindweed differs from other, less susceptible species. Field bindweed plants were treated with 3.3 kBq C-14-aminocydopyrachlor by spotting a single leaf mid-way up the stem with 10 mu l of herbicide solution. Plants were then harvested at set intervals over 192 h after treatment (HAT). Aminocyclopyrachlor absorption reached a maximum of 48.3% of the applied radioactivity by 48 HAT. A translocation pattern of herbicide movement from the treated leaf into other plant tissues emerged, revealing a nearly equal aminocyclopyrachlor distribution between the treated leaf, aboveground tissue, and belowground tissue of 13, 14, and 14% of the applied radioactivity by 192 HAT. Over the time-course, no soluble aminocyclopyrachlor metabolites were observed, but there was an increase in radioactivity recovered bound in the nonsoluble fraction. These results suggest that aminocyclopyrachlor has greater translocation to belowground plant tissue in field bindweed compared with results from other studies with other herbicides and other weed species, which could explain the increased level of control observed in the field. The lack of soluble metabolites also suggests that very little metabolism occurred over the 192 h time course. C1 [Lindenmayer, R.

TI Increased Purple Nutsedge (Cyperus rotundus) Tuber Sprouting with Diurnally Fluctuating Temperatures SO WEED SCIENCE LA English DT Article DE Alternating temperatures; germination; vegetative propagule ID DENSITY POLYETHYLENE MULCH; ALTERNATING TEMPERATURES; SEED-GERMINATION; HERBICIDE DISSIPATION; METHYL-BROMIDE; ESCULENTUS; SOLARIZATION; EMERGENCE; TOMATO; SQUASH AB Purple nutsedge is among the most troublesome weeds of vegetables in the Southeast US and a substantial impediment in the search for methyl bromide alternatives. Greater understanding of the environmental cues that regulate tuber sprouting may assist in improved nutsedge management. Experiments were conducted to evaluate the effect of diurnal temperature variation on sprouting of purple nutsedge tubers. Two temperature regimes were evaluated: the first averaged 28 C, with daily fluctuations ranging from 0 to 19.5 C; the second temperature regime averaged 16 C, with daily fluctuations ranging from 0 to 18.5 C. When average temperature was 28 C, cumulative tuber sprouting ranged from 88 to 92%, with no detectable differences among diurnal fluctuations. The high average temperature in the first study may have negated any type of enforced sprouting suppression. However, when average temperature was lowered to 16 C (simulating early spring diurnal fluctuations under polyethylene mulch), there was a positive linear correlation between maximum tuber sprouting and temperature variation. With an average temperature of 16 C, the absence of temperature variation resulted in 52% purple nutsedge sprouting, while 87% sprouting occurred when daily temperature varied 18.5 C at the same average temperature. The use of various types of mulching material can affect average soil temperatures and diurnal variations, potentially shifting nutsedge emergence. Further studies are needed to determine if these data on tuber sprouting in response to alternating temperatures can facilitate more efficient weed management.

The relationship between cumulative emergence and hydrothermal time (HTT) was described by a sigmoid growth function (Chapman). HIT was calculated with a set of water potentials and temperatures, iteratively used, to determine the base water potential and base temperature. Emergence of ripgut brome was well described with a Chapman function. The newly-developed function was validated with four sets of data, two of them belonging to a third season in the same field and the other two coming from independent data from Southern Spain. The model also successfully described the emergence in different field management and tillage systems. This model may be useful for predicting ripgut brome emergence in winter cereal fields of semiarid Mediterranean regions.

TI Simulated yield and profitability of five potential crops for intensifying the dryland wheat-fallow production system SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE Crop simulation; Soil water; Modeling; RZWQM2; DSSAT; Soil water; Triticale; Canola; Millet; Corn ID CENTRAL GREAT-PLAINS; PRECIPITATION STORAGE EFFICIENCY; LEGUME GREEN FALLOW; SOIL-WATER CONTENT; WINTER-WHEAT; CROPPING SYSTEMS; TILLAGE SYSTEMS; HYBRID MODEL; RZWQM; ROTATIONS AB Greater precipitation use efficiency (PUE) and economic returns by increasing cropping frequency through the addition of summer crops to the dryland winter wheat-fallow (WF) cropping system have been reported in the semiarid Central Great Plains of USA. However, due to the highly variable nature of precipitation and uncertain water availability, selection of a crop with assured positive net returns to add to the system to increase cropping frequency is a challenge in the absence of reliable seasonal precipitation forecasts. The objective of this study was to evaluate long-term yields and net returns of several potential summer crops at various soil water contents at planting to assess their potential use in increasing dryland cropping frequency. Three grain crops [corn (Zea mays L.), canola (Brassica napus), and proso millet (Panicum miliaceum L.)] and two forage crops [foxtail millet (Setaria italica L Beauv.) and spring triticale (X Triticosecale rimpaui Wittm.)] for which the Root Zone Water Quality Model (RZWQM2) had been calibrated at Akron, CO and/or Sidney, NE, were selected for investigation through modeling. The calibrated model was used to simulate yield responses of the crops to 25, 50, 75 and 100% of plant available water (PAW) in the soil profile at planting using recorded weather data from Akron, CO and Sidney, NE (1948-2008). Average costs of production and 10-yr average commodity prices for northeast Colorado were used to calculate net returns for each of the crops at the varying PAW levels. All crops showed significant (p < 0.05) simulated yield increases in response to increasing initial PAW levels when those changes occurred in the entire 0-180 cm soil profile. The two forage crops gave greater net returns than the three grain crops for all initial PAW levels when calculated with 10-yr average prices received. Among the grain crops, proso millet was slightly more profitable than corn at Akron, while corn was the least profitable crop at Sidney. Using current commodity prices (13 September 2011) resulted in proso millet being the least profitable crop at Sidney, while corn was the most profitable grain crop at Akron and showed net returns that were similar to those found for the forage crops. The results of this study may guide the selection of a spring- or summer-planted crop and help farmers assess risk as they contemplate intensifying the WF system by using a measure or estimate of PAW at planting.

Objective: The objective was to evaluate the effects of supplementation with 1000 IU vitamin D-3/d on calcium absorption. Design: In a double-blind, placebo-controlled trial, we randomly assigned 64 children to 1000 IU vitamin D-3/d (n = 32) or placebo (n = 32) for 8 wk. Stable isotopes were used to assess calcium absorption. The main outcome measure was calcium absorption before and after supplementation. Results: All of the data are shown as means +/- SDs. At baseline, vitamin D intake was 221 +/- 79 IU/d and calcium intake was 830 +/- 197 mg/d. Baseline serum 25-hydroxyvitamin D [25(OH)D] was not significantly correlated with fractional or total calcium absorption. After 8 wk, with baseline values used as a covariate, no differences were seen in fractional or total calcium absorption based on supplementation group (P = 0.75 and 0.36, respectively). Supplemented children had a significant increase in 25(OH)D concentrations (from 27.7 +/- 7.4 to 36.0 +/- 10.3 ng/mL; P < 0.0001) and a decrease in parathyroid hormone (from 21.4 +/- 10.4 to 12.9 +/- 7.1 pg/mL; P < 0.001); no significant changes in the placebo group were observed. No adverse side effects were noted in either group. Conclusions: Vitamin D-3 supplementation at 1000 IU/d increases 25(OH)D and decreases parathyroid hormone in children with average vitamin D intakes below the dietary recommendations of the Institute of Medicine. However, no significant effects of this change on calcium absorption occurred. This trial was registered at clinicaltrials.gov as NCT 00868738. Am J Clin Nutr 2013;97:217-23.

TI Elemental chemistry of sand-boil discharge used to trace variable pathways of seepage beneath levees during the 2011 Mississippi River flood SO APPLIED GEOCHEMISTRY LA English DT Article ID AQUIFERS; GROUNDWATER; COLUMN AB Shortly after peak stage of the 2011 Mississippi River flood, water samples were collected from the river, from sand boils near the toe of the levee, and from actively flowing relief wells over a 55 km stretch north of Vicksburg, MS. Two distinct pathways for seepage under the levee were identified based on the elemental composition of water samples. Sand boil discharge was similar to water from relief wells only at a location where the levee sits on ancient channel fill deposits. Seepage at this site is forced along a deeper pathway beneath the fine-grained channel fill. Where the levee sits on sandy point bar deposits, shallow flow beneath the levee is unimpeded. The chemical composition of discharge from sand boils at these sites was clearly not just river water, nor a simple mixture of river and groundwater, but appears to reflect unique weathering or redox interactions occurring within the upper portion of the alluvial aquifer. Distinguishing shallow and deep seepage pathways may prove useful for evaluating site specific risk of levee failure. (C) 2012 Elsevier Ltd. All rights reserved.

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

Wheat straw (WS) was used as a feedstock. In addition to butanol, acetone (78.05 x 10(6) kg/year) and ethanol (28.54 x 10(6) kg/year) would also be produced. The total capital cost for this plant was $193.07 x 10(6). This exercise was based in part on data generated in our laboratory and in part on data obtained from literature. The design, mass balance, and energy balance simulations were performed using SuperPro Designer (Version 8.5003, 2012). For butanol production wheat straw would be pretreated with dilute (1% v/v) sulfuric acid at 121 degrees C for 1 h followed by separate hydrolysis (using enzymes), fermentation and recovery. Enzyme cost for wheat straw hydrolysis was adapted from literature ($0.16/kg butanol). Utilities which included steam/high pressure steam, cooling/chilling water, and electricity represented the major cost of the operation (49.18%) followed by raw materials (26.81%). Based on batch fermentation of wheat straw hydrolysate and distillative recovery of acetone butanol ethanol (ABE), butanol production cost was estimated to be $1.30/kg for a grass-rooted/green-field plant. Application of a membrane recovery process could reduce this price to $1.00/kg for a plant annexed to an existing distillery. Published by Elsevier Ltd. C1 [Qureshi, N.; Saha, B. C.; Cotta, M.

Specimens with varying surface layer thicknesses, foam densities (polystyrene foam), and processing temperatures were tested. Using the initially recommended cone irradiance of 35 kW/m(2), different flammability parameters were measured. In comparison to particleboards, the foam core panels generally had much higher heat release rates, somewhat higher heat of combustion and much higher smoke production due to the EPS-foam component of tested panels. The time to ignition and total heat release did not vary significantly among the samples, although certain trends could be explained. The effects of variations in specimen foam densities and processing temperatures on the flammability parameters were not very significant. However, the flammability properties improved towards that of the reference particleboard as the surface layer thickness increased from 3 to 5 mm.

TI Cone calorimeter evaluation of two flame retardant cotton fabrics SO FIRE AND MATERIALS LA English DT Article DE flame retardant; gray cotton fabric; fire barrier; fire blocker; 16 CFR 1633; cone calorimeter; diammonium phosphate ID COMBINATIONS; NONWOVENS AB Unbleached (gray) cotton needle-punched nonwoven (NW) fabrics with 12.5% polypropylene scrim were treated with two phosphatenitrogen-based flame retardant (FR) formulations, Southern Regional Research Center (SRRC)-1 and SRRC-2. The SRRC-1 formulation contains diammonium phosphate as the FR chemical along with urea and dimethyloldihydroxyethyleneurea. Because a trace amount of formaldehyde was still expected to be released from SRRC-1-treated FR cotton under high heat, it was preferable to eliminate the dimethyloldihydroxyethyleneurea, leading to the revised formulation SRRC-2. It has a higher content of diammonium phosphate and did not use the polyethylene emulsion that was in SRRC-1. Both formulations were of low cost as they were developed at SRRC using industrial grade chemicals. The fabrics were evaluated with a cone calorimeter using three heat flux levels, 20, 30, and 50?kW/m2. On the basis of the overall cone calorimeter results for heat released and ignition times, FR NW fabrics that were treated with SRRC-2 were found to be slightly superior in flammability properties to those treated with the earlier SRRC-1 formulation, but the differences were statistically insignificant. Both preparations were much less flammable than the untreated control cotton NW fabrics. Compared with the untreated NW fabrics, the FR fabrics had higher visible smoke production.

No information is available on the comparative pathogenicity of different strains of V. scophthalmi toward olive flounder. In this study, high- and low-virulence strains (HVS and LVS, respectively) were compared in terms of their pathogenic characteristics, including adhesion and survival, superoxide dismutase (SOD) activity, and extracellular products (ECP) of bacterial cells. The cell-mediated defense of macrophages from olive flounder against V. scophthalmi infection in vitro was also investigated. The results demonstrated that the SOD activity of the HVS was higher than that of the LVS. The number of viable cells of the HVS in serum increased by two log units after 18 h, whereas that of the LVS decreased. The number of cells of the HVS in skin mucus increased significantly while that of the LVS remained constant. The LD50 values of the HVS and LVS ECP toward olive flounder were 10.14 and 15.99 mu g protein/g fish, respectively. The ECP were positive for naphthol-AS-BI-phosphohydrolase, lipase, gelatinase, and leucine arylamidase. The extracellular O-2 (-) overflow and intracellular O-2 (-) concentration of macrophages induced by the HVS were lower than those induced by the LVS. Significantly more nitric oxide was produced by the HVS than by the LVS. C1 [Qiao, Guo; Park, Soo Il] Pukyong Natl Univ, Dept Aquat Life Med, Pusan 608737, South Korea.

TI Computer-based synthetic data to assess the tree delineation algorithm from airborne LiDAR survey SO GEOINFORMATICA LA English DT Article DE Computers synthetic data; Tree delineation; Algorithm; LiDAR ID LASER SCANNER DATA; LEAF-AREA INDEX; SPATIAL INTERPOLATION; STAND CHARACTERISTICS; INDIVIDUAL TREES; FOREST STRUCTURE; CROWN DIAMETER; CANOPY-HEIGHT; TIMBER VOLUME; BIOMASS AB Small Footprint LiDAR (Light Detection And Ranging) has been proposed as an effective tool for measuring detailed biophysical characteristics of forests over broad spatial scales. However, by itself LiDAR yields only a sample of the true 3D structure of a forest. In order to extract useful forestry relevant information, this data must be interpreted using mathematical models and computer algorithms that infer or estimate specific forest metrics. For these outputs to be useful, algorithms must be validated and/or calibrated using a sub-sample of 'known' metrics measured using more detailed, reliable methods such as field sampling. In this paper we describe a novel method for delineating and deriving metrics of individual trees from LiDAR data based on watershed segmentation. Because of the costs involved with collecting both LiDAR data and field samples for validation, we use synthetic LiDAR data to validate and assess the accuracy of our algorithm. This synthetic LiDAR data is generated using a simple geometric model of Loblolly pine (Pinus taeda) trees and a simulation of LiDAR sampling. Our results suggest that point densities greater than 2 and preferably greater than 4 points per m2 are necessary to obtain accurate forest inventory data from Loblolly pine stands. However the results also demonstrate that the detection errors (i.e. the accuracy and biases of the algorithm) are intrinsically related to the structural characteristics of the forest being measured. We argue that experiments with synthetic data are directly useful to forest managers to guide the design of operational forest inventory studies. In addition, we argue that the development of LiDAR simulation models and experiments with the data they generate represents a fundamental and useful approach to designing, improving and exploring the accuracy and efficiency of LiDAR algorithms.

TI Effect of clothing weight on body weight SO INTERNATIONAL JOURNAL OF OBESITY LA English DT Article DE clothing weight; body weight; clinical assessment; outdoor temperature; season AB BACKGROUND: In clinical settings, it is common to measure weight of clothed patients and estimate a correction for the weight of clothing, but we can find no papers in the medical literature regarding the variability in clothing weight of adults with weather, season and gender. METHODS: Fifty adults (35 women) were weighed four times during a 12-month period with and without clothing. Clothing weights were determined and regressed against minimum, maximum and average daily outdoor temperature. RESULTS: The average clothing weight (+/- s.d.) throughout the year was significantly greater in men than in women (1.2 +/- 0.3 vs 0.8 +/- 0.3 kg, P<0.0001). The average within-person minimum and the average within-person maximum clothing weights across the year were 0.9 +/- 0.2 and 1.5 +/- 0.4 kg for men, and 0.5 +/- 0.2 and 1.1 +/- 0.4 kg for women, respectively. The within-person s.d. in clothing weight was 0.3 kg for both men and women. Over the 55 degrees C range in the lowest to the highest outdoor temperatures, the regressions predicted a maximal change in clothing weight of only 0.4 kg in women and 0.6 kg in men. CONCLUSION: The clothing weight of men is significantly greater than that of women, but there is little variability throughout the year. Therefore, a clothing adjustment of approximately 0.8 kg for women and 1.2 kg for men is appropriate regardless of outdoor temperature.

TI Disinfectant and Antibiotic Susceptibility Profiles of Escherichia coli O157:H7 Strains from Cattle Carcasses, Feces, and Hides and Ground Beef from the United States SO JOURNAL OF FOOD PROTECTION LA English DT Article ID GEL-ELECTROPHORESIS PROTOCOLS; COLI O157-H7; ACID-RESISTANCE; SALMONELLA; FOOD; ANTISEPTICS; MECHANISMS; OUTBREAKS; PULSENET; SORBATE AB The disinfectant and antibiotic susceptibility profiles of 344 Escherichia coli O157:H7 strains from cattle carcasses, feces, and hides and ground beef from the United States were determined. A low prevalence of antibiotic resistance was observed (14%). The highest prevalences of resistance were to sulfisoxazole (10.5%), tetracycline (9.9%), streptomycin (7%), and chloramphenicol (4.9%). Four strains were resistant to eight antibiotics (two strains from ground beef and one strain each from hide and preevisceration carcass swabs of cull cattle at harvest). Pulsed-field gel electrophoresis analysis of the E. coli O157:H7 strains revealed two major groups (designated 1 and 2) composed of 17 and 20 clusters, respectively. Clusters 1A, 1B, 1C, and 1G.1 were associated with multidrug-resistant strains. There was no observed correlation between disinfectant resistance and antibiotic resistance. Sixty-nine (20%) of the 344 strains were resistant to chlorhexidine or benzalkonium chloride or the MICs of benzyldimethyldodecylammonium chloride were elevated. Inducible resistance was observed at elevated concentrations of antibiotics (1.4%) and disinfectants (6.1%). The highest rate of disinfectant inducible resistance was to OdoBan, quaternary ammonium chlorides, and the surface disinfectants F25, FS512, and MG, which are used in dairies, restaurants, and food processing plants. High MICs (1,024 to 4,096 mu g/ml) of acetic, lactic, and citric acids were found. The decreasing order of acid potency based on molar MICs (MICsmolar) was acetic, citric, and lactic acid. The correlation of the concentration of dissociated organic acids and MICsmolar strongly suggests that the observed inhibition of E. coli O157:H7 was primarily due to dissociated forms of the acids.

In-line milk filters were also tested in the 2007 survey. The objective of this study was to determine the prevalence of antimicrobial resistance among Salmonella enterica isolates from bulk milk and milk filters in the NAHMS Dairy 2002 and. 2007 surveys and to further characterize resistant isolates. Susceptibilities to 15 antibiotics were determined for 176 Salmonella isolates of 26 serotypes using an automated antimicrobial susceptibility system. Resistant isolates were screened by PCR for the presence of the extended-spectrum beta-lactamase (bla(CMY)) gene and class I integrons and further characterized by pulsed-field gel electrophoresis. Thirty isolates (17.0%) representing six S. enterica serotypes exhibited resistance to at least one antimicrobial agent (serotypes Newport [14 of 14 isolates exhibited resistance], Dublin [7 of 7], Typhimurium [3 of 5], Kentucky [4 of 22], Anatum [1 of 13], and Infantis [1 of 2]). Twenty isolates (11.4%), including all 14 Newport, 3 Dublin, 2 Typhimurium, and 1 Infantis isolate, displayed the typical multidrug-resistant, bla(CMY)-positive (MDR-AmpC) phenotype which included resistance to ampicillin, chloramphenicol, streptomycin, sulfonamide, and tetracycline, plus resistance to amoxicillin-clavulanic acid and extended-spectrum cephalosporins. Five of the MDR-AmpC isolates carried class I integrons (2.8%). Two-enzyme (XbaI and BlnI) pulsed-field gel electrophoresis discerned clades within serotypes and, together with the resistance profiles, identified strains that appeared to have persisted temporally and geographically. These results suggest that there is a low but appreciable risk of infection with MDR Salmonella from consumption of nonpasteurized milk and dairy products. C1 [Van Kessel, J.

TI Initial Contamination of Chicken Parts with Salmonella at Retail and Cross-Contamination of Cooked Chicken with Salmonella from Raw Chicken during Meal Preparation SO JOURNAL OF FOOD PROTECTION LA English DT Article ID REPUBLIC-OF-IRELAND; DOMESTIC KITCHEN; GROWTH-KINETICS; PREVALENCE; CARCASSES; POULTRY; NUMBER; CAMPYLOBACTER; ATTACHMENT AB The current study was undertaken to acquire data on contamination of chicken parts with Salmonella at retail and to acquire data on cross-contamination of cooked chicken with Salmonella from raw chicken during meal preparation. Whole raw chickens (n = 31) were obtained from local retail stores and cut into two wings, two breasts without skin or bones, two thighs, and two drumsticks. Data for cross-contamination were obtained by cutting up a sterile, cooked chicken breast with the same board and knife used to cut up the raw chicken. The board, knife, and latex gloves used by the food handler were not rinsed or washed before cutting up the sterile, cooked chicken breast, thus providing a worst-case scenario for cross-contamination. Standard curves for the concentration of Salmonella bacteria in 400 ml of buffered peptone water after 6 h of incubation of chicken parts as a function of the initial log number of Salmonella bacteria inoculated onto chicken parts were developed and used to enumerate Salmonella bacteria. Standard curves were not affected by the type of chicken part but did differ (P < 0.05) among the five isolates of Salmonella examined. Consequently, Salmonella bacteria were enumerated on naturally contaminated chicken parts using a standard curve developed with the serotype of Salmonella that was isolated from the original sample. The prevalence of contamination was 3% (4 of 132), whereas the incidence of cross-contamination was 1.8% (1 of 57). The positive chicken parts were a thigh from chicken 4, which contained 3 CFU of Salmonella enterica serotype Kentucky, and both wings, one thigh, and one cooked breast portion from chicken 15, which all contained 1 CFU of serotype 8,20:-:z(6). These results indicated that the poultry industry is providing consumers in the studied area with chicken that has a low prevalence and low number of Salmonella bacteria at retail and that has a low incidence and low level of cross-contamination of cooked chicken with Salmonella from raw chicken during meal preparation under a worst-case scenario.

TI Growth Potential of Clostridium perfringens from Spores in Acidified Beef, Pork, and Poultry Products during Chilling SO JOURNAL OF FOOD PROTECTION LA English DT Article ID INJECTED PORK; GERMINATION; OUTGROWTH; MEAT; ROAST AB The ability of Clostridium perfringens to germinate and grow in acidified ground beef as well as in 10 commercially prepared acidified beef, pork, and poultry products was assessed. The pH of ground beef was adjusted with organic vinegar to achieve various pH values between 5.0 and 5.6; the pH of the commercial products ranged from 4.74 to 6.35. Products were inoculated with a three-strain cocktail of C. perfringens spores to achieve ca. 2-log (low) or 4-log (high) inoculum levels, vacuum packaged, and cooled exponentially from 54.4 to 7.2 degrees C for 6, 9, 12, 15, 18, or 21 h to simulate abusive cooling; the U.S. Department of Agriculture, Food Safety and Inspection Service (USDA-FSIS) recommends a cooling time of 6.5 h. Total germinated C. perfringens populations were determined after plating on tryptose-sulfite-cycloserine agar and incubating the plates anaerobically at 37 degrees C for 48 h. In addition, C. perfringens growth from spores was assessed at an isothermal temperature of 44 degrees C. Growth from spores was inhibited in ground beef with a pH of 5.5 or below, even during extended cooling from 54.4 to 7.2 degrees C in 21 h. In ground beef with a pH of 5.6, the growth was >1 log after 18 h of cooling from 54.4 to 7.2 degrees C. However, 15 h of cooling controlled the growth to <1 log, regardless of the inoculum level. In addition, no growth was observed in any product with a pH ranging from 4.74 to 5.17, both during exponential abusive cooling periods of up to 21 h and during storage for 21 h at 44 degrees C. While <1-log growth of C. perfringens from spores was observed in the pH 5.63 product cooled exponentially from 54.4 to 7.2 degrees C in 15 h or less, the pH 6.35 product supported growth, even after 6 h of cooling from 54.4 to 7.2 degrees C. These challenge tests demonstrate that adjustment of ground beef to pH of 5.5 or less and of barbeque products to pH of 5.63 or less inhibits C. perfringens spore germination and outgrowth during extended cooling periods from 54.4 to 7.2 degrees C up to 15 h. Therefore, safe cooling periods for products with homogeneous, lower pHs can be substantially longer. C1 [Juneja, Vijay K.] ARS, USDA, Eastern Reg Res Ctr, Wyndmoor, PA 19038 USA.

Cost-effective risk-reduction requires a detailed and comprehensive understanding of how Salmonella Enteritidis infections in hens result in deposition of the pathogen inside eggs. The present study sought to resolve some incompletely defined aspects of the relationship between Salmonella Enteritidis oral-exposure dose levels in experimentally infected laying hens and the frequency and location of subsequent egg contamination. In two trials, groups of specific-pathogen-free hens were experimentally inoculated with oral doses of 10(4), 10(6), or 10(8) CPU of a phage type 4 Salmonella Enteritidis strain. Eggs were collected 5 to 23 days postinoculation, and the yolk and albumen of each egg were cultured separately to detect Salmonella Enteritidis contamination. Larger oral doses of Salmonella Enteritidis administered to hens were associated with significant increases in the frequencies of both yolk and albumen contamination. Moreover, Salmonella Enteritidis was found in the albumen of a far-higher proportion of contaminated eggs from hens given the largest dose than from the other two groups. Salmonella Enteritidis contamination was detected in 0.7% of yolk and 0.2% of albumen samples after inoculation of hens with 10(4) CPU, 4.0% of yolk and 1.7% of albumen samples after inoculation with 10(6) CPU, and 6.5% of yolk and 10.8% of albumen samples after inoculation with 10(8) CPU. These results demonstrate that oral-exposure doses of Salmonella Enteritidis for laying hens can significantly affect both the frequency and location of deposition of this pathogen inside eggs.

The governing equations are the 1D mass and momentum conservation equations for sediment-laden flow and the sediment continuity equation for both bed load and suspended-load transport. The Rouse profile is modified to consider the nonequilibrium transport of suspended sediment. The spatial lag between the instantaneous flow properties (e. g., velocity, bed shear stress) and the rate of bed load transport in unsteady flow is quantified by using an adaptation length, which is derived theoretically by applying the momentum principle in the bed load layer. This new method for calculating the adaptation length is verified using data from several experiments and yields better results than other empirical formulas for a wide range of shear stress. The nonequilibrium model is applied to simulate a series of laboratory dam-break flows over erodible beds, and the simulated results agree well with the experimental measurements.

TI Inception Point for Embankment Dam Stepped Spillways SO JOURNAL OF HYDRAULIC ENGINEERING-ASCE LA English DT Article DE Roller-compacted concrete; Dam safety; Dams; Embankment; Energy dissipation; Aeration; Air entrainment; Spillways; Rehabilitation; Inception point ID SKIMMING FLOWS; ENERGY-DISSIPATION; HYDRAULICS; CHANNEL AB Retrofitting embankment dams with stepped spillways has become a common design practice, particularly for those dams that change hazard classification from low to high. For embankment dams retrofitted with stepped spillways, the chute length is often insufficient for developing aerated flow or an inception point. The inception point is a key spillway design parameter used in energy dissipation, flow depth, and air entrainment prediction relationships. Original research for developing an inception-point relationship for stepped spillways was based on primarily gravity (theta >= 26.6 degrees) stepped spillways, with the majority having an ogee crest control section. The resulting, inception-point relationship tends to overestimate the inception-point location for broad-crested weir stepped spillways (theta <= 26.6 degrees) when the Froude surface roughness (F-*) is less than 10. Consequently, research on broad-crested weir stepped spillways retrofitted for embankment dams has been conducted to provide an optimized inception-point relationship. This study provides additional data allowing further refinement (i.e., F-* <= 28) of the inception-point relationship for broad-crested stepped spillways (theta <= 26.6 degrees), and it provides a new relationship for broad-crested weir stepped spillways for F-* > 28.

In the present study, essential oils obtained from heartwood samples of Juniperus virginiana L., Juniperus occidentalis Hook. and Juniperus ashei J. Buchholz were evaluated for wound healing and anti-inflammatory activities by using in vivo experimental methods. The essential oils were obtained by the supercritical carbon dioxide extraction method. Linear incision and circular excision wound models were performed for the wound-healing activity assessment. The tissues were also evaluated for the hydroxyproline content as well as histopathologically. To evaluate the anti-inflammatory activity of the essential oils, the test used was an acetic acid-induced increase in capillary permeability. The essential oil of J. occidentalis showed the highest activity on the in vivo biological activity models. Additionaly, the oil of J. virginiana was found highly effective in the anti-inflammatory activity method. The experimental data demonstrated that essential oil of J. occidentalis displayed significant wound-healing and anti-inflammatory activities.

TI Dairy Food Consumption and Meal-Induced Cortisol Response Interacted to Influence Weight Loss in Overweight Women Undergoing a 12-Week, Meal-Controlled, Weight Loss Intervention SO JOURNAL OF NUTRITION LA English DT Article ID PITUITARY-ADRENAL AXIS; ALPHA-LACTALBUMIN INCREASES; NEUTRAL AMINO-ACIDS; OBESE WOMEN; VULNERABLE SUBJECTS; INSULIN-RESISTANCE; METABOLIC SYNDROME; ABDOMINAL OBESITY; PROTEIN-RICH; STRESS AB Dairy food enhances weight loss in animal models, possibly by modifying the metabolic effects of cortisol. This study determined in overweight women (ages 20.0-45.9 y; n = 51) whether including dairy food in an energy-restricted diet affects cortisol concentrations and whether differences in provoked cortisol explain the magnitude of weight loss. Women received either an adequate amount of dairy food (AD), the equivalent of >= 711 mL/d milk, or a low amount of dairy food (LD), the equivalent to <= 238 mL/d milk, in a 12-wk, energy-restricted dietary intervention. Participants were tested in a 12-h laboratory visit, which included 2 standard meals and a dinner buffet that was consumed ad libitum. Salivary cortisol was measured from waking to bedtime. Energy restriction increased (P <= 0.04) the minimum and decreased (P <= 0.02) the diurnal amplitude in the salivary cortisol concentration from baseline to postintervention. Energy restriction enhanced the dinner meal-stimulated salivary cortisol response (DMR) (P <= 0.02) but only in the LD group. Compared with the LD treatment, the AD treatment induced (P <= 0.04) greater reductions in body weight and fat, but only in women characterized as having a baseline DMR (responders) (n = 26); weight and fat lost in the AD and LD groups were similar in nonresponders (n = 25). Overall, energy restriction dampened diurnal salivary cortisol fluctuations [symptomatic of hypothalamic-pituitary-adrenal (HPA) axis dysfunction] and enhanced dinner meal-stimulated salivary cortisol concentrations. The AD treatment prevented the latter. Furthermore, certain phenotypic markers of HPA axis function may help to expose the weight-reducing effects of consuming dairy food. J. Nutr. 143: 46-52, 2013.

TI Cross-Sectional Time Series and Multivariate Adaptive Regression Splines Models Using Accelerometry and Heart Rate Predict Energy Expenditure of Preschoolers SO JOURNAL OF NUTRITION LA English DT Article ID PHYSICAL-ACTIVITY; YOUNG-CHILDREN; VALIDATION; CALIBRATION; ADOLESCENTS; VALIDITY AB Prediction equations of energy expenditure (EE) using accelerometers and miniaturized heart rate (HR) monitors have been developed in older children and adults but not in preschool-aged children. Because the relationships between accelerometer counts (ACs), HR, and EE are confounded by growth and maturation, age-specific EE prediction equations are required. We used advanced technology (fast-response room calorimetry, Actiheart and Actigraph accelerometers, and miniaturized HR monitors) and sophisticated mathematical modeling [cross-sectional time series (CSTS) and multivariate adaptive regression splines (MARS)] to develop models for the prediction of minute-by-minute EE in 69 preschool-aged children. CSTS and MARS models were developed by using participant characteristics (gender, age, weight, height), Actiheart (HR+AC_x) or ActiGraph parameters (AC_x, AC_y, AC_z, steps, posture) [x, y, and z represent the directional axes of the accelerometers], and their significant 1- and 2-min lag and lead values, and significant interactions. Relative to EE measured by calorimetry, mean percentage errors predicting awake EE (-1.1 +/- 8.7%, 0.3 +/- 6.9%, and -0.2 +/- 6.9%) with CSTS models were slightly higher than with MARS models (-0.7 +/- 6.0%, 0.3 +/- 4.8%, and -0.6 +/- 4.6%) for Actiheart, ActiGraph, and ActiGraph+HR devices, respectively. Predicted awake EE values were within +/- 10% for 81-87% of individuals for CSTS models and for 91-98% of individuals for MARS models. Concordance correlation coefficients were 0.936, 0.931, and 0.943 for CSTS EE models and 0.946, 0.948, and 0.940 for MARS EE models for Actiheart, ActiGraph, and ActiGraph+HR devices, respectively. CSTS and MARS models should prove useful in capturing the complex dynamics of EE and movement that are characteristic of preschool-aged children. J. Nutr. 143: 114-122, 2013.

Thermogravimetry (TG), a combination of TG and Fourier transform infrared spectrometer (TG-FTIR), X-ray diffraction (XRD), and differential thermal analysis (DTA) were used to investigate thermal decomposition of bamboo. The calorific value and smoke release process of both bamboos were also tested, respectively. The results from TG indicated that degradation process of sinocalamus affinis and moso bamboo was similar, but their degradation temperatures were different. The main decomposition occurred in the second step and about 68.70 and 64.63% masses degraded for sinocalamus affinis and moso bamboo, whose temperature of maximum mass loss was 319 and 339 A degrees C, respectively. DTA curve showed that the thermal decomposition of both bamboos was an absorbance heat process. TG-FTIR analysis showed that the main pyrolysis products of both bamboos were similar, including absorbed water (H2O), methane gas (CH4), carbon dioxide (CO2), acids and aldehydes, ammonia gas (NH3). The calorific value of moso bamboo (19,291 J g(-1) K-1) was higher than that of sinocalamus affinis (18,082 J g(-1) K-1). The initial time of smoke release process of moso bamboo was later, and its maximum smoke density was higher than that of sinocalamus affinis. The difference was probably attributed to different compositions and structure of sinocalamus affinis and moso bamboo. The results from this research are very helpful to better design manufacturing process of bio-energy, made from bamboo, by gasification and pyrolysis methods.

Inferences on migration routes can be made from tracking genetic types in populations found in specific habitats and testing how they are linked to other types. Water samples were taken over a 4-year period from waterways in the Upper Oconee River Watershed, Georgia, to recover isolates of thermophilic Campylobacter. The isolates were typed by multilocus sequence typing (MLST) and analyzed to determine the overall diversity of Campylobacter in that environment. Forty-seven independent isolates were recovered from 560 samples (8.4 %). Two (similar to 4 %) isolates were Campylobacter coli, three (similar to 6 %) isolates were putatively identified as Campylobacter lari, and the remaining 42 (similar to 90 %) were Campylobacter jejuni. The C. jejuni and C. coli isolates were typed by the Oxford MLST scheme. Thirty sequence types (STs) were identified including 13 STs that were not found before in the MLST database, including 24 novel alleles. Of the 17 previously described STs, 10 have been isolated from humans, 6 from environmental water, and 6 from wild birds (five types from multiple sources). Seven sites had multiple positive samples, and on two occasions, the same ST was isolated at the same site. The most common type was STST61 with four isolates, and the most common clonal complex was CC179 with nine isolates. CC179 has been commonly associated with environmental water. Although some Campylobacter STs that were found in the Oconee River engage in widespread migration, most are tightly associated with or unique to environmental water sources. C1 [Meinersmann, R.

TI Genetic dissection of grain beta-glucan and amylose content in barley (Hordeum vulgare L.)

Quantitative trait loci (QTL) associated with BG have been reported in traditional barley varieties with intermediate levels of BG, but no QTL studies have been reported in hull-less barley varieties with high BG levels. In this study, QTL analysis was performed to identify markers linked to high BG and amylose in the hull-less barley varieties Falcon (4-5 % BG) and Azhul (8-9 % BG) using a newly developed recombinant inbred line (RIL) mapping population. The population was grown over 3 years (2007-2009) at sites in Yuma, AZ, USA; Leeston, New Zealand; Aberdeen, ID, USA; and Tetonia, ID, USA. We identified 17 QTL associated with either BG or amylose content. QTL contributing to high BG were located on chromosomes 3H, 4H, 5H, 6H and 7H, while QTL contributing to amylose were located on chromosomes 1H, 5H and 7H. Additionally, we identified QTL affecting both BG and amylose content located on chromosomes 1H and 7H. Transgressive segregation was observed in some of the RILs and exceptions were discovered contradicting an inverse relationship between BG and amylose. This work will provide the basis for gene cloning and marker-assisted selection in combination with traditional field selection to improve barley breeding for high BG content.

TI Targeted mapping of quantitative trait locus regions for rhizomatousness in chromosome SBI-01 and analysis of overwintering in a Sorghum bicolor x S. propinquum population SO MOLECULAR BREEDING LA English DT Article DE Perennialism; Perenniality; Rhizomes; Sorghum; Sorghum propinquum ID HALEPENSE L PERS; JOHNSON GRASS; GENES; EXPRESSION; EVOLUTION; BIOLOGY; ORIGIN; BARLEY; CROPS; RICE AB While rhizome formation is intimately associated with perennialism and the derived benefit of sustainability, the introduction of this trait into temperate-zone adapted Sorghum cultivars requires precise knowledge of the genetics conditioning this trait in order to minimize the risk of weediness (e.g., Johnsongrass, S. halepense) while maximizing the productivity of perennial sorghum. As an incremental step towards dissecting the genetics of perennialism, a segregating F4 heterogeneous inbred family derived from a cross between S. bicolor and S. propinquum was phenotyped in both field and greenhouse environments for traits related to over-wintering and rhizome formation. An unseasonably cold winter in 2011 provided high selection pressure, and hence 74.8 % of the population did not survive. This severe selection pressure for cold tolerance allowed the resolution of two previously unidentified over-wintering quantitative trait locus (QTL) and more powerful correlation models than previously reported. Conflicting with previous reports, a maximum of 33 % of over-wintering variation could be explained by above-ground shoot formation from rhizomes; however, every over-wintering plant exhibited rhizome growth. Thus, while rhizome formation is required for over-wintering, other factors also determine survival in this interspecific population. The fine mapping of a previously reported rhizome QTL on sorghum chromosome SBI-01 was conducted by targeting this genomic region with additional simple sequence repeat markers. Fine mapping reduced the 2-LOD rhizome QTL interval from similar to 59 to similar to 14.5 Mb, which represents a 75 % reduction in physical distance and a 53 % reduction in the number of putative genes in the locus.

The objective of this study was to develop a closed-tube, gel-free assay for high-throughput genotyping of leaf rust resistance locus Lr21. Polymorphism identified from re-sequencing of a 2.4-kb fragment covering the functional region of the Lr21 gene from the second to the fourth indels was targeted for assay development. The generated sequence data revealed the 88- or 105-bp indel in the first intron of the Lr21 gene in the selected resistant cultivars compared to susceptible US spring and winter wheat cultivars. Allele-specific primers for a KASPar assay were designed around the junction of the indel at position 1,346 bp. The marker was tested on a panel of 384 US wheat lines and found to be effective in differentiating resistant and susceptible genotypes.

In order to improve the BB resistance of two elite, traditional BB-susceptible Basmati varieties (Taraori Basmati and Basmati 386), we utilized the strategy of limited marker-assisted backcrossing for introgression of two major BB resistance genes, Xa21 and xa13, coupled with phenotype-based selection for improvement of their plant type and yield. Improved Samba Mahsuri, an elite high-yielding, fine-grain-type BB-resistant rice variety served as donor for BB resistance. Backcross-derived improved Basmati lines at BC1F5 possessing a single resistance gene (i.e. either Xa21 or xa13) displayed moderate resistance to BB, while lines possessing both Xa21 and xa13 showed significantly higher levels of resistance. Two-gene pyramid lines (Xa21 + xa13) possessing good grain and cooking quality similar to their respective traditional Basmati parents, short plant stature (< 110 cm plant height) and higher grain yield than the recurrent parent(s) were identified and advanced. This work demonstrates the successful application of marker-assisted selection in conjunction with phenotype-based selection for targeted introgression of multiple resistance genes into traditional Basmati varieties along with improvement of their plant stature and yield.

A sphere encompasses ideas relevant to restoration and the people working within similar areas of influence or expertise. Increased capacity within a sphere and a higher degree of coalescing among spheres predict a greater probability of successful restoration. We illustrate this with Castanea dentata, a foundation forest tree in North America that was annihilated by an introduced pathogen; the species is a model that effectively merges biotechnology, reintroduction biology, and restoration ecology. Because of C. dentata's ecological and social importance, scientists have aggressively pursued blight resistance through various approaches. We summarize recent advancements in tree breeding and biotechnology that have emerged from C. dentata research, and describe their potential to bring new tools to bear on socio-ecological restoration problems. Successful reintroduction of C. dentata will also depend upon an enhanced understanding of its ecology within contemporary forests. We identify a critical need for a deeper understanding of societal influences that may affect setting and achieving realistic restoration goals. Castanea dentata may serve as an important model to inform reintroduction of threatened plant species in general and foundation forest trees in particular.

We tested whether elevated atmospheric CO2 might ameliorate these effects by improving plant water-use efficiency. We examined the effects of CO2 and water availability on seedlings of two native (Populus deltoides spp. monilifera, Salix exigua) and three exotic (Elaeagnus angustifolia, Tamarix spp., Ulmus pumila) western North American riparian species in a CO2-controlled glasshouse, using 1-m-deep pots with different water-table decline rates. Low water availability reduced seedling biomass by 70-97%, and hindered the native species more than the exotics. Elevated CO2 increased biomass by 15%, with similar effects on natives and exotics. Elevated CO2 increased intrinsic water-use efficiency (Delta C-13(leaf)), but did not increase biomass more in drier treatments than wetter treatments. The moderate positive effects of elevated CO2 on riparian seedlings are unlikely to counteract the large negative effects of increased aridity projected under climate change. Our results suggest that increased aridity will reduce riparian seedling growth despite elevated CO2, and will reduce growth more for native Salix and Populus than for drought-tolerant exotic species.

Collection of a cumulative drip sample by placing collection vessels under the processing line could potentially capture a more representative sample of bacterial populations associated with an entire flock with less labor than individual bird rinses. The purpose of this study was to evaluate a cumulative drip sampling method for recovery of Campylobacter spp. and 3 types of quality indicator organisms from broiler carcasses. Cumulative drip and WCR samples were collected on 14 d from a commercial broiler processing facility over a 3-mo period. No statistically significant difference was demonstrated between the WCR and cumulative drip sampling methods in recovery of Campylobacter spp., total aerobes, Enterobacteriaceae, or Escherichia coli associated with the postevisceration samples (P > 0.01). Analysis of the pyrosequencing census data demonstrated high interbird variability and indicates cumulative sampling may be required to obtain fully representative sampling of a flock. For most bacterial taxa, the relative abundance in individual WCR was correlated with cumulative drip samples, but some taxa were undercounted or missed entirely by individual WCR. Consequently, individual carcass rinses may not be representative of the flock microbial community. The cumulative drip sampling technique may save labor and provide a more representative summary of process control in poultry processing facilities. C1 [Line, J. E.; Oakley, B. B.; Stern, N.

Importantly, family support for physical activity declined in subjects who had more visits to health care professionals, which is worrisome, as this represents another risk factor for sedentary behavior in this vulnerable cohort that must be overcome for successful, sustained behavioral change. Programs supporting positive attitudes of both adolescents and their families toward physical activity will be necessary to optimize exercise adoption and adherence as a means to combat the obesity epidemic in childhood and adolescence.

Between 2002 and 2004, we sampled small mammal communities and measured vegetation structure at 185 locations across a range of disturbance regimes in a shortgrass prairie ecosystem in southeastern Colorado, USA. At each sampling location, the local disturbance regime was some combination of varying intensity of livestock grazing, military training activity, and fire. Vegetation structural characteristics measured included percent bare ground, basal cover, litter, shrub density, and mean grass and shrub height. Rodent communities were described by richness, diversity, total and per capita biomass, and species abundances. Northern grasshopper mice (Onychomys leucogaster), Ord's kangaroo rats (Dipodomys ordii), silky pocket mice (Perognathus flavus), western harvest mice (Reithrodontomys megalotis), white-footed mice (Peromyscus leucopus), southern plains wood rats (Neotoma micropus), thirteen-lined ground squirrels (Spermophilus tridecemlineatus), deer mice (Peromyscus maniculatus), and spotted ground squirrels (Spermophilus spilosoma) accounted for > 99 % of all captures. Canonical correlation analysis was used to assess the relationship between small mammals and vegetation structure. The first two canonical variates explained over 50 % of the variation in vegetation structure and were related to the ratio of bare ground to basal coverage and litter accumulation. Rodent community indices were most strongly related to litter accumulation and shrub density, though the models had low explanatory power. Our results agreed with published findings regarding microhabitat associations and indicated small mammal communities benefited from a system of interacting disturbances and the resulting landscape mosaic.

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

Here, we report the first documentation of Oplostomus fuligineus in Kenya, a related scarab of O. haroldi, and distribution, diversity and pattern of damage of the two scarab species on honey bee colonies. Sequence analyses of mitochondrial cytochrome oxidase I gene revealed that there was sufficient sequence divergence to separate both Oplostomus beetles. The same molecular marker separated O. haroldi according to place of origin in Kenya. We further show from analysis of feeding behavioural patterns that the two scarab species damaged honey bee combs similarly causing the most damage on brood through feeding; O. haroldi (80%), with O. fuligineus (100%). We discuss our results in relation to the threats these scarabs may pose to bee health in Kenya.

Bee bread was more acidic than the pollen, and that made by EHB was slightly more acidic than AHB. Protein concentration in bee bread was similar for both subspecies and lower than in the pollen. In general, amino acid concentrations were higher in bee bread compared with pollen. The only exception was tryptophan. Concentrations of most amino acids in bee bread made by either EHB or AHB were similar. Both subspecies consumed more bee bread made by AHB than EHB. EHB and AHB consumed similar amounts of each type of bee bread, but protein concentrations in AHB were higher than in EHB. Differences in protein acquisition between AHB and EHB might reflect environmental adaptations related to the geographic region where each evolved and could contribute to the successful establishment of AHB populations in the New World.

Codenitrification and denitrification by fungi are additional pathways producing N-2 in soils. However, fungal codenitrification and denitrification have not been well investigated in agricultural soils. To evaluate bacterial and fungal processes contributing to N-2 production, molecular and N-15 isotope analyses were conducted with soil samples collected at six different agricultural fields in the United States. Denitrifying and anammox bacterial abundances were measured based on quantitative PCR (qPCR) of nitrous oxide reductase (nosZ) and hydrazine oxidase (hzo) genes, respectively, while the internal transcribed spacer (ITS) of Fusarium oxysporum was quantified to estimate the abundance of codenitrifying and denitrifying fungi. N-15 tracer incubation experiments with (NO3-)-N-15 or (NH4+)-N-15 addition were conducted to measure the N-2 production rates from anammox, denitrification, and codenitrification. Soil incubation experiments with antibiotic treatments were also used to differentiate between fungal and bacterial N2 production rates in soil samples. Denitrifying bacteria were found to be the most abundant, followed by F. oxysporum based on the qPCR assays. The potential denitrification rates by bacteria and fungi ranged from 4.118 to 42.121 nmol N-2-N g(-1) day(-1), while the combined potential rates of anammox and codenitrification ranged from 2.796 to 147.711 nmol N-2-N g(-1) day(-1). Soil incubation experiments with antibiotics indicated that fungal codenitrification was the primary process contributing to N-2 production in the North Carolina soil. This study clearly demonstrates the importance of fungal processes in the agricultural N cycle. C1 [Long, Andrew; Song, Bongkeun] Univ N Carolina, Dept Biol & Marine Biol, Wilmington, NC 28401 USA.

We observed that population sizes of Salmonella enterica serovar Typhimurium SL1344 increased 56-fold when inoculated alone onto cilantro leaves, versus 2,884-fold when coinoculated with Dickeya dadantii, a prevalent pathogen that macerates plant tissue. A similar trend in S. enterica populations was observed for soft-rotted lettuce leaves. Transcriptome analysis of S. enterica cells that colonized D. dadantii-infected lettuce and cilantro leaves revealed a clear shift toward anaerobic metabolism and catabolism of substrates that are available due to the degradation of plant cells by the pectinolytic pathogen. Twenty-nine percent of the genes that were upregulated in cilantro macerates were also previously observed to have increased expression levels in the chicken intestine. Furthermore, multiple genes induced in soft rot lesions are also involved in the colonization of mouse, pig, and bovine models of host infection. Among those genes, the operons for ethanolamine and propanediol utilization as well as for the synthesis of cobalamin, a cofactor in these pathways, were the most highly upregulated genes in lettuce and cilantro lesions. In S. Typhimurium strain LT2, population sizes of mutants deficient in propanediol utilization or cobalamin synthesis were 10- and 3-fold lower, respectively, than those of the wild-type strain in macerated cilantro (P < 0.0002); in strain SL1344, such mutants behaved similarly to the parental strain. Anaerobic conditions and the utilization of nutrients in macerated plant tissue that are also present in the animal intestine indicate a niche overlap that may explain the high level of adaptation of S. enterica to soft rot lesions, a common postharvest plant disease.

Effects of As-contaminated drinking water and paddy straw on the excretion of As through milk, urine, and dung of dairy cows (n = 240) were studied in As-prone areas of Bangladesh. Mean (+/- SEM) total As (inorganic plus organic) concentration in drinking water, paddy straw [dry weight dw)], cow's urine (specific gravity adjusted to 1.035), dung (dw), and milk (wet weight) were 89.6 +/- A 6.5 mu g/l, 1,114.4 +/- A 57.3 mu g/kg, 123.6 +/- A 7.6 mu g/l, 1,693.0 +/- A 65.1 mu g/kg, and 26.2 +/- A 2.8 mu g/l, respectively. Significantly (p < 0.01) greater As was in Boro straw (1,386.9 +/- A 71.8 mu g/kg) than Aus (702.4 +/- A 67.1 mu g/kg) and Aman (431.7 +/- A 28.8 mu g/kg) straw and in straw irrigated with shallow (1,697.3 +/- A 81.9 mu g/kg) than deep well water (583.6 +/- A 62.7 mu g/kg) and surface water (511.8 +/- A 30.0 mu g/kg). Significant (p < 0.01) positive correlations were found between As contents of cow's urine and drinking water (r = 0.92) as well as cow dung and straw (r = 0.82). Concentrations of As in cow urine, dung, and milk were increased with the relative increment of As in drinking water and/or straw. These results provide evidence that dairy cows excrete ingested As mainly through urine and dung; thus, As biotransformation through milk remains low. This low concentration of As in milk may be of concern when humans are exposed to multiple sources of As simultaneously. Moreover, As in cow dung could be an environmental issue in Bangladesh.

Drawing on studies of many migratory insects, we posed the hypothesis that JH influences migratory capacity and oogenesis in the rice leaf roller, Cnaphalocrocis medinalis. We treated adults moths (days 1, 2 and 3 postemergence) with the JH analog (JHA), methoprene, and then recorded the influences of JHA treatments on reproduction. JHA treatment on day 1 postemergence, but not on the other days, shortened the preoviposition period, although JHA did not influence total fecundity, oviposition period, or longevity. We infer day 1 postemergence is the JH-sensitive stage to influence reproduction. Therefore, we treated moths on day 1 postemergence with JHA and recorded flight capacity, flight muscle mass, and triacylglycerol (TAG) accumulation. JHA treatments did not influence flight speed, but led to reductions in flight durations and flight distances. At day 3 posttreatment (PT), JHA-treated females flew shorter times and less distance than the controls; JHA-treated males, however, only flew shorter times than the controls. JHA treatments led to reductions in flight muscle mass in females at days 23 PT and reductions in TAG content in females at day 3 PT, but, these parameters were not influenced by JHA in males. These findings strongly support our hypothesis, from which we infer that JH is a major driver in C. medinalis oogenesis-flight syndrome tradeoffs. Our data also reveal a JH-sensitive stage in adulthood during which JH influences the oocyte-flight syndrome in C. medinalis. (C) 2012 Wiley Periodicals, Inc.

Sensitivity to circulating levels of insulin has been shown to regulate the growth of specific traits in a dose-dependent manner in response to environmental conditions in a diversity of insect species. Alternative phenotypes in insects manifest in a variety of morphologies such as the sexually dimorphic and male dimorphic horned beetles. Large males of the sexually dimorphic dung beetle Onthophagus nigriventris develop a thoracic horn up to twice the length of the body whereas small males and females never develop this horn. The regulation of this dimorphism is known to be nutrition dependent for males. We focused on the insulin signaling pathway as a potential regulator of this dimorphism. We sequenced a full-length gene transcript encoding the O. nigriventris insulin receptor (OnInR), which is the receptor for circulating insulin and insulin-like peptides in animals. We show that the predicted OnInR protein is similar in overall amino acid identity to other insulin receptors (InRs) and is most closely related phylogenetically to insect InRs. Expression of the OnInR transcript was found during development of imaginal tissues in both males and females. However, expression of OnInR in the region where a horn would grow of small males and female was significantly higher than in the horn tissues of large males at the end of growth. This variation in OnInR expression between sexes and morphs indicates a role for the InR in polymorphic horn development. (C) 2012 Wiley Periodicals, Inc.

Andrew Mora, Miguel Canals TI Long-term decline of a winter-resident bird community in Puerto Rico SO BIODIVERSITY AND CONSERVATION LA English DT Article DE American Redstart; Black-and-white Warbler; Ovenbird; Partners in Flight; Songbird population declines ID LAND BIRDS; NEW-WORLD; ABUNDANCE; SONGBIRD; CLIMATE; GREATER; MODELS AB Despite concern expressed two decades ago, there has been little recent discussion about continuing declines of migrant bird populations. Monitoring efforts have been focused almost exclusively on the breeding grounds. We describe the long-term decline of a winter-resident bird population in Guanica Commonwealth Forest, Puerto Rico, one of the last remaining tracts of high-quality tropical dry forests in the Caribbean. The winter bird community has exhibited dramatic declines, with constant-effort mist netting now capturing about one-third as many birds as it did 20 years ago. Population estimates for the three most common species have declined dramatically, even though survival rates have remained constant, and other species are now virtually absent from a site where they once were fairly common. Although explanations for these declines are speculative, particularly because they involve multiple species, we argue that the strength and duration of these declines in well-preserved dry forest within a biosphere reserve should stimulate renewed discussion of migrant population trends and comparison with other recent monitoring activities.

In this system, the bioreactor was fed with a concentrated sugar solution (250-500 g L-1 glucose). The bioreactor was bled semi-continuously to avoid accumulation of inhibitory chemicals and products. The continuous system was operated for 504 h (21 days) after which the fermentation was intentionally terminated. The bioreactor produced 461.3 g ABE from 1,125.0 g total sugar in 1 L culture volume as compared to a control batch process in which 18.4 g ABE was produced from 47.3 g sugar. These results demonstrate that ABE fermentation can be operated in an integrated continuous one-stage fermentation and product recovery system for a long period of time, if butanol and other microbial metabolites in the bioreactor are kept below threshold of toxicity.

Oak-tree wood chips were first gasified to syngas over a commercial pilot plant downdraft gasifier. The raw wood syngas contains about 47% N-2, 21% CO, 18% H-2, 12% CO2 2% CH4 and trace amounts of impurities. A purification reaction system was designed to remove the impurities in the syngas such as moisture. oxygen, sulfur, ammonia, and tar. The purified syngas meets the requirements for catalytic conversion to liquid fuels. A multi-functional catalyst was developed and tested for the catalytic conversion of wood syngas to SATFs. It was demonstrated that liquid fuels similar to commercial aviation turbine fuels (Jet A) was successfully synthesized from bio-syngas. (C) 2012 Elsevier Ltd. All rights reserved.

The pretreated wood chips were disk-milled with pretreatment spent liquor and water, and the solid fraction was separated from the liquor stream. The liquor was neutralized and concentrated through vacuum evaporation. Quasi-simultaneous enzymatic saccharification of the cellulosic solids and combined fermentation with the concentrated liquor was conducted at up to 20% total solids loading. Fed-batching of the solids facilitated liquefaction and saccharification, as well as managing instantaneous inhibitor concentrations. At a commercial cellulase (CTec2) loading of only 9 FPU or 0.06 mL/g untreated wood, a maximum ethanol titer of 47.4 g/L was achieved, resulting in a calculated yield of 285 L/tonne of wood using Saccharomyces cerevisiae YRH400 at 35 degrees C and pH 5.5.

Although it is known that an increase in soil moisture reduces emissions, the range of soil moisture for minimizing emissions without risking pest control, is not well defined for various types of soils. With two column studies, we determined the effect of different soil moisture levels on emission and distribution of 1,3-dichloropropene and chloropicrin in three different textured soils. Results on sandy loam and loam soils showed that by increasing soil moisture from 30% to 100% of field capacity (FC), peak fluxes were lowered by 77-88% and their occurrences were delayed 5-15 h, and cumulative emissions were reduced 24-49%. For the sandy soil, neither peak fluxes nor the cumulative emissions were significantly different when soil moisture increased from 30% to 100% FC. Compared to the drier soils, the wetter soils retained consistently higher fumigant concentrations in the gas-phase, suggesting efficacy may not be impacted in these soils. The air-filled porosity positively and linearly correlated with the cumulative emission loss across all soil types indicating that it may serve as a good indicator for estimating emissions. These laboratory findings can be further tested under field conditions to conclude what irrigation regime should be used for increasing soil water content before fumigant application that can achieve maximum emission reduction and uniform fumigant distribution with high exposure index values.

High cholesterol levels, which are closely related to dietary habits, are a major contributor to CVD. In this article, we study whether changes in food prices are related to cholesterol levels and whether taxes or subsidies on particular foods would be effective in lowering cholesterol levels and, consequently, CVD costs. We find that prices of vegetables, processed foods, whole milk and whole grains are significantly associated with blood cholesterol levels. Having analyzed the costs and benefits of government interventions, we find that a subsidy of vegetables and whole grains would be an efficient way to reduce CVD expenditures.

Data from these studies have historically been interpreted in a qualitative, dichotomous yes or no manner without analysis of doseresponse relationships. This article is based upon the work of an international multi-sector group that examined how quantitative doseresponse relationships for in vitro and in vivo genetic toxicology data might be used to improve human risk assessment. The group examined three quantitative approaches for analyzing doseresponse curves and deriving point-of-departure (POD) metrics (i.e., the no-observed-genotoxic-effect-level (NOGEL), the threshold effect level (Td), and the benchmark dose (BMD)), using data for the induction of micronuclei and gene mutations by methyl methanesulfonate or ethyl methanesulfonate in vitro and in vivo. These results suggest that the POD descriptors obtained using the different approaches are within the same order of magnitude, with more variability observed for the in vivo assays. The different approaches were found to be complementary as each has advantages and limitations. The results further indicate that the lower confidence limit of a benchmark response rate of 10% (BMDL10) could be considered a satisfactory POD when analyzing genotoxicity data using the BMD approach. The models described permit the identification of POD values that could be combined with mode of action analysis to determine whether exposure(s) below a particular level constitutes a significant human risk. Subsequent analyses will expand the number of substances and endpoints investigated, and continue to evaluate the utility of quantitative approaches for analysis of genetic toxicity doseresponse data.

TI A software engineering perspective on environmental modeling framework design: The Object Modeling System SO ENVIRONMENTAL MODELLING & SOFTWARE LA English DT Article DE Object Modeling System; Environmental modeling frameworks; Modeling and simulation; Software engineering; Software design ID COMPONENTS AB The environmental modeling community has historically been concerned with the proliferation of models and the effort associated with collective model development tasks (e.g., code generation, data transformation, etc.). Environmental modeling frameworks (EMFs) have been developed to address this problem, but much work remains before EMFs are adopted as mainstream modeling tools. Environmental model development requires both scientific understanding of environmental phenomena and software developer proficiency. EMFs support the modeling process through streamlining model code development, allowing seamless access to data, and supporting data analysis and visualization. EMFs also support aggregation of model components into functional units, component interaction and communication, temporal-spatial stepping, scaling of spatial data, multi-threading/multi-processor support, and cross-language interoperability. Some EMFs additionally focus on high-performance computing and are tailored for particular modeling domains such as ecosystem, socio-economic, or climate change research. The Object Modeling System Version 3 (OMS3) EMF employs new advances in software framework design to better support the environmental model development process. This paper discusses key EMF design goals/constraints and addresses software engineering aspects that have made OMS3 framework development efficacious and its application practical, as demonstrated by leveraging software engineering efforts outside of the modeling community and lessons learned from over a decade of EMF development. Software engineering approaches employed in OMS3 are highlighted including a non-invasive lightweight framework design supporting component-based model development, use of implicit parallelism in system design, use of domain specific language design patterns, and cloud-based support for computational scalability. The key advancements in EMF design presented herein may be applicable and beneficial for other EMF developers seeking to better support environmental model development through improved framework design.

NBP was positive (C sink) in year 1 (2004) and generally decreased over the 50-year simulation period. More intensive management scenarios, those with a high percentage of clear-cut or a doubling of harvest area, decreased average NBP by a maximum of 58% and vegetation C by a maximum of 29% compared to the current harvest regime (base scenario), while less intensive harvest scenarios (low clear-cut or low area harvested) increased NBP. Yearly mean NPP changed less than 3% under the different scenarios. Vegetation carbon increased in all scenarios by at least 12%, except the two most intensive harvest scenarios, where vegetation carbon decreased by more than 8%. Varying the amount of harvest residue retention had a more profound effect on NBP than on vegetation C. Removing additional residue resulted in greater NBP over the 50-year period compared to the base simulation. Results from the seven model simulations suggest that managing for carbon storage and carbon sequestration are not mutually exclusive in Midwest forests. (C) 2012 Elsevier Ltd. All rights reserved.

The enzyme was discovered on the basis of its ability to attack aldotetraohexenuronic acid (HexA-2Xyl-4Xyl-4Xyl, HexA3Xyl3), releasing the reducing-end xylose residue. XYN IV exhibited catalytic properties incompatible with previously described endo-beta-1,4-xylanases of this fungus, XYN I, XYN II and XYN III, and the xylan-hydrolyzing endo-beta-1,4-glucanase EG I. XYN IV was able to degrade several different beta-1,4-xylans, but was inactive on beta-1,4-mannans and beta-1,4-glucans. It showed both exo-and endo-xylanase activity. Rhodymenan, a linear soluble beta-1,3-beta-1,4-xylan, was as the best substrate. Linear xylooligosaccharides were attacked exclusively at the first glycosidic linkage from the reducing end. The gene xyn4, encoding XYN IV, was also isolated. It showed clear homology with xylanases classified in glycoside hydrolase family 30, which also includes glucanases and mannanases. The xyn4 gene was expressed slightly when grown on xylose and xylitol, clearly on arabinose, arabitol, sophorose, xylobiose, xylan and cellulose, but not on glucose or sorbitol, resembling induction of other xylanolytic enzymes from T. reesei. A recombinant enzyme prepared in a Pichia pastoris expression system exhibited identical catalytic properties to the enzyme isolated from the T. reesei culture medium. The physiological role of this unique enzyme remains unknown, but it may involve liberation of xylose from the reducing end of branched oligosaccharides that are resistant toward beta-xylosidase and other types of endoxylanases. In terms of its catalytic properties, XYN IV differs from bacterial GH family 30 glucuronoxylanases that recognize 4-O-methyl-d-glucuronic acid (MeGlcA) substituents as substrate specificity determinants.

In the present study, common wheat (AABBDD) and four related species, including T. urartu (A(u)A(u)), Aegilops speltoides (SS), Ae. tauschii (DD), and T. turgidum (AABB) were sampled for the presence of novel alleles at Pinb2v-A1, Pinb2v-B1/Pinb2v-S1 and Pinb2v-D1 loci corresponding to common wheat puroindoline b-2 variants. Nine new alleles were identified at these loci, designated Pinb2v-A1a through Pinb2v-A1c, Pinb2v-S1a through Pinb2v-S1e, and Pinb2v-D1a. Alignment of puroindoline variants or alleles from common wheat and its relatives indicated that all alleles in diploid wheats are attributed to single nucleotide substitution when compared with puroindoline b-2 variants in polyploids. Deduced amino acid sequences showed that all three alleles at Pinb2v-A1 locus and four alleles (Pinb2v-S1a, Pinb2v-S1b, Pinb2v-S1c and Pinb2v-S1e) at the Pinb2v-S1 locus could not be normally translated due to the presence of premature stop codons, whereas Pinb2v-D1a at the Pinb2v-D1 locus and Pinb2v-S1d at the Pinb2v-S1 locus could be normally translated, possibly suggesting that the puroindoline b-2 variant in Ae. tauschii was more highly conserved than those in T. urartu and Ae. speltoides. Meanwhile, puroindoline b-2 variant could be normally translated in all of the durum and common wheat cultivars surveyed. None of the puroindoline b-2 alleles previously identified in durum and common wheat were found in the diploid genome donors examined here, even though a greater diversity of alleles were found in diploid wheat compared to polyploid wheat. These results likely reflect the evolutionary history of tetraploid and hexaploid wheats, although it may be that puroindoline b-2 variant alleles have been selected for stability and functionality in common and durum wheat. This study provides a survey of puroindoline b-2 variants in common wheat and its relatives, and provides useful information for understanding the genetic diversity of puroindoline-like genes and their duplication events in wheat.

T. Chang Genetic Resources Center were determined after storage for 20.5-30.5 years. Germination of seeds that had been stored in the base collection was generally high (> 70 %), whereas germination was more variable for seeds stored in the active collection. Samples with lower viability after storage in the active collection were likely to have lower viability after storage in the base collection. There were significant differences in the moisture content-eRH relationship of the seeds depending on whether the seeds had been stored in the active or base collection. Based on re-test data for regular seed samples regenerated in 1979-1980 and stored in the active collection for up to 31 years, estimates of the time for ability to germinate to fall to 50 % (p (50)) ranged from 54 to 997 years. For the same seed samples stored in the base collection for approximately 31 years, ability to germinate has been maintained and germination increased due to improved procedures. The ability to germinate of base collection samples was also generally higher than that of 'safety duplicate' samples of the same seed lots that had been sent to the National Center for Genetic Resources Preservation, USA in 1981 and stored at -18 A degrees C. This may have been due to uptake of moisture either during processing for dispatch or as a consequence of poor packaging material. The results are discussed in relation to long-term seed storage and genebank management. C1 [Hay, Fiona R.; de Guzman, Flora; Hamilton, N.

TI A sediment budget for a small semiarid watershed in southeastern Arizona, USA SO GEOMORPHOLOGY LA English DT Article DE Sediment budget; Erosion; Sediment redistribution; Rangeland; Sediment yield ID SOUTHWESTERN UNITED-STATES; BASIN; YIELD; SCALE; RATES AB A sediment budget was developed for a 43.7 ha and a nested 3.7 ha semiarid, shrub dominated watershed based on hydrologic, geomorphic, erosion, and sediment data collected from 1963 through 2006 on the USDA-ARS Walnut Gulch Experimental Watershed in the southwestern US. Sediment budgets based on such extensive and intensive field campaigns over several decades are rare. The sediment budget was balanced with a high degree of confidence because the study watershed is controlled by an earth dam at the outlet. Although the channel network is well developed and incising in the steeper reaches of the watershed, hillslopes are the dominant source of sediment, contributing 85% of the overall total sediment yield. Erosion and sediment redistribution were driven by highly variable rainfall and runoff during July, August, and September. Sediment transfers are influenced by channel abstractions and the presence of the outlet dam, which created conditions for deposition in the pond approach reach. Although earth dams are ubiquitous throughout the southwestern US, and they can provide a measure of outlet sediment yield, these outlet measurements may be insufficient to interpret temporal and spatial variability in watershed sediment dynamics. Identification of dominant processes and sediment sources is critical for determining management actions that will improve rangeland conditions. Published by Elsevier B.V. C1 [Nichols, M.

Naturally aflatoxin-contaminated (59 ppb) peanut meal dispersions were adjusted to pH 2.1 or pH 9.1, with or without additional protease and/or a clay absorbent, and the resulting soluble extracts derived from these dispersions were spray dried. Clay addition during processing minimally affected spray-drying yields, protein powder solubility or antioxidant capacities, whereas these properties were significantly altered by pH and protease treatments. Spray-dried hydrolysates produced from peanut meal treated with clay contained significantly less aflatoxin than hydrolysates produced without clay; the effects of pH or enzyme on aflatoxin content were minimal. Peanut meal treated with Alcalase, and clay yielded spray-dried hydrolysates with enhanced antioxidant capacity and increased solubility compared to unhydrolysed controls and had aflatoxin levels below 1 ppb.

TI Analytical solution for the advection-dispersion transport equation in layered media SO INTERNATIONAL JOURNAL OF HEAT AND MASS TRANSFER LA English DT Article DE Layered media; Integrating factor; Advection-dispersion eigenvalue problem; Classic integral transform technique ID POROUS-MEDIA; DIFFUSION AB The advection-dispersion transport equation with first-order decay was solved analytically for multilayered media using the classic integral transform technique (CITT). The solution procedure used an associated non-self-adjoint advection-diffusion eigenvalue problem that had the same form and coefficients as the original problem. The generalized solution of the eigenvalue problem for any numbers of layers was developed using mathematical induction, establishing recurrence formulas and a transcendental equation for determining the eigenvalues. The orthogonality property of the eigenfunctions was found using an integrating factor that transformed the non-self-adjoint advection-diffusion eigenvalue problem into a purely diffusive, self-adjoint problem. The performance of the closed-form analytical solution was evaluated by solving the advection-dispersion transport equation for two- and five-layer media test cases which have been previously reported in the literature. Additionally, a solution featuring first-order decay was developed. The analytical solution reproduced results from the literature, and it was found that the rate of convergence for the current solution was superior to that of previously published solutions.

TI Short-term soil nutrient impact in a real-time drain field soil moisture-controlled SDI wastewater disposal system SO IRRIGATION SCIENCE LA English DT Article ID IRRIGATION; VERTISOLS; NITROGEN; VOLUME AB The Alabama Black Belt area is widespread of Vertisols that are generally unsuitable for conventional septic systems; nonetheless, systems of this type have been widely used in this region for decades. In order to explore alternatives for these conventional septic systems, a real-time soil moisture-controlled subsurface drip irrigation wastewater disposal system was integrated and field tested in a Houston Vertisol for 1 year. This automated disposal system effectively limited wastewater disposal during unfavorably wet drain field conditions. However, the resulting nutrient supply into the drain field was observed to be in surplus to crop growth requirements. Soil cores taken at the conclusion of the 1-year study indicated evidence of nitrate and phosphorus leaching. Available nitrates in the top 100 cm of soil showed a decreasing trend but were higher than all other parallel controls. Soil crop-available phosphorous in the soil increased below the drip line, as result that may be ascribed to soil cracking that was not properly controlled at the test site. Despite the demonstrated deficiencies, integrating timing of wastewater disposal with soil moisture conditions can supplement existing municipal or decentralized community wastewater treatment disposal systems.

Our objective was to evaluate the effect of cooling HT cows during the dry period on gene expression of the mammary gland and peripheral blood mononuclear cells (PBMC). Cows were dried off 46 d before their expected calving and assigned to 2 treatments, HT or cooling (CL). Cows in the CL group were cooled with sprinklers and fans whereas HT cows were not. After parturition, all cows were housed in a freestall barn with cooling. The PBMC were isolated at dry-off and at -20, 2, and 20 d relative to calving from a subset of cows (HT, n = 9; CL, n = 10), and mammary biopsies were taken at the same intervals (HT, n = 7; CL, n = 6) for RNA extraction. Gene expression was assessed using a custom multiplex gene expression assay based on traditional reverse transcription-PCR. Genes involved in prolactin (PRL) signaling [PRL receptor long form, PR,L receptor short form, suppressor of cytokine signaling (SOCS)2, SOCS3, IGF2, IGF binding protein 5, and cyclin D1] fatty acid metabolism (acetyl-CoA carboxylase alpha (ACACA) and lipoprotein lipase (LPL)], and IGF1 were evaluated in mammary tissue, and genes related to fatty acid metabolism [ACACA, fatty acid synthase (FASN), and LPL], cytokine production [IL6, IL8, and tumor necrosis factor (TNF)], and IGF1 were evaluated in PBMC. No differences were observed in PRL signaling or fatty acid metabolism gene expression in the mammary gland. In PBMC, HT cows had greater mRNA expression of IGF1 and TNF during the transition period relative to CL and upregulated IL8 and downregulated FASN mRNA expression at 2 d relative to calving. We conclude that cooling HT cows during the dry period alters expression of genes involved in cytokine production and lipid metabolism in PBMC. C1 [Tao, S.; Bubolz, J. W.; Thompson, I.

TI Replacing alfalfa or red clover silage with birdsfoot trefoil silage in total mixed rations increases production of lactating dairy cows SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE birdsfoot trefoil; condensed tannins; milk yield ID ENSILED FORAGE LEGUMES; LOTUS-CORNICULATUS L; MILK UREA NITROGEN; CONDENSED TANNINS; AMINO-ACIDS; DRY-MATTER; PROTEIN-DEGRADATION; ANIMAL NUTRITION; INTERNAL MARKERS; DETERGENT FIBER AB The objective of this study was to compare milk production and nutrient utilization in dairy cattle fed silage made from alfalfa (AL) or red clover (RC) versus birdsfoot trefoil (BFT) selected for low, normal, and high levels of condensed tannins. Condensed tannin contents of the 3 BFT silages were 8, 12, and 16 g/kg of DM by butanol-HCl assay. Twenty-five multiparous Holstein cows (5 fitted with ruminal cannulas) were blocked by days in milk and randomly assigned within blocks to incomplete 5 x 5 Latin squares. Diets contained [dry matter (DM) basis] about 60% AL, 50% RC, or 60% of 1 of the 3 BFT; the balance of dietary DM was largely from high-moisture corn plus supplemental crude protein from soybean meal. Diets were balanced to approximately 17% crude protein and fed for four 3-wk periods; 2 wk were allowed for adaptation and production data were collected during the last week of each period. No differences existed in DM intake or milk composition due to silage source, except that milk protein content was lowest for RC. Yields of milk, energy-corrected milk, fat, protein, lactose, and solids-not-fat were greater for the 3 BFT diets than for diets containing AL or RC. Feeding BFT with the highest condensed tannin content increased yield of milk, protein, and solids-not-fat compared with BFT containing the lowest amount of condensed tannin. Moreover, milk-N/N-intake was higher, and milk urea nitrogen concentration and urinary urea-N excretion were lower for diets with normal levels of BFT than for AL or RC diets. Feeding RC resulted in the highest apparent digestibility of DM, organic matter, neutral detergent fiber, acid detergent fiber, and hemicellulose and lowest ruminal concentrations of ammonia and free amino acids. Ruminal branched-chain volatile fatty acid levels were lowest for RC diets and diets with high levels of BFT and highest for the AL diet. Overall, diets containing BFT silage supported greater production than diets containing silage from AL or RC. The results indicated that feeding BFT or other legume silages containing condensed tannins can enhance performance and N utilization in lactating dairy cows. C1 [Hymes-Fecht, U. C.; Broderick, G.

TI Methods to approximate reliabilities in single-step genomic evaluation SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE genomic prediction; reliability; single-step evaluation; best linear unbiased predictor ID GENETIC EVALUATION; RELATIONSHIP MATRICES; FULL PEDIGREE; INFORMATION; TRAIT; PREDICTIONS; SELECTION; ACCURACY; MODEL; INTEGRATION AB Reliability of predictions from single-step genomic BLUP (ssGBLUP) can be calculated by matrix inversion, but that is riot feasible for large data sets. Two methods of approximating reliability were developed based on the decomposition of a function of reliability into contributions from records, pedigrees, and genotypes. Those contributions can be expressed in record or daughter equivalents. The first approximation method involved inversion of a matrix that contains inverses of the genomic relationship matrix and the pedigree relationship matrix for genotyped animals. The second approximation method involved only the diagonal elements of those inverses. The 2 approximation methods were tested with a simulated data set. The correlations between ssGBLUP and approximated contributions from genomic information were 0.92 for the first approximation method and 0.56 for the second approximation method; contributions were inflated by 62 and 258%, respectively. The respective correlations for reliabilities were 0.98 and 0.72. After empirical correction for inflation, those correlations increased to 0.99 and 0.89. Approximations of reliabilities of predictions by ssGBLUP are accurate and computationally feasible for populations with up to 100,000 genotyped animals. A critical part of the approximations is quality control of information from single nucleotide polymorphisms and proper scaling of the genomic relationship matrix.

TI Genomic imputation and evaluation using high-density Holstein genotypes SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE genomic evaluation; imputation; marker density ID PREDICTIONS; TRAITS; PANELS AB Genomic evaluations for 161,341 Holsteins were computed by using 311,725 of 777,962 markers on the IIlumina BovineHD Genotyping BeadChip (HD). Initial edits with 1,741 HD genotypes from 5 breeds revealed that 636,967 markers were usable but that half were redundant. Holstein genotypes were from 1;510 animals with HD markers, 82,358 animals with 45;187 (50K) markers, 1,797 animals with 8,031 (8K) markers, 20,177 animals with 6,836 (6K) markers, 52,270 animals with 2;683 (3K) markers; and 3,229 nongenotyped dams (OK) with >90% of haplotypes imputable because they had 4 or more genotyped progeny. The Holstein HD genotypes were from 1;142 US, Canadian, British; and Italian sires, 196 other sires, 138 cows in a US Department of Agriculture research herd (Beltsville; MD), and 34 other females. Percentages of correctly imputed genotypes were tested by applying the programs findhap and FImpute to a simulated chromosome for an earlier population that had only 1;112 animals with HD genotypes and none with 8K genotypes. For each chip, 1% of the genotypes were missing and 0.02% were incorrect initially. After imputation of missing markers with findhap; percentages of genotypes correct were 99.9% from HD; 99.0% from 50K, 94.6% from 6K, 90.5% from 3K, and 93.5% from OK. With FImpute, 99.96% were correct from HD, 99.3% from 50K, 94.7% from 6K, 91.1% from 3K, and 95.1% from OK genotypes. Accuracy for the 3K and 6K genotypes further improved by approximately 2 percentage points if imputed first to 50K and then to HD instead of imputing all genotypes directly to HD. Evaluations were tested by using imputed actual genotypes and August 2008 phenotypes to predict deregressed evaluations of US bulls proven after August 2008. For 28 traits tested; the estimated genomic reliability averaged 61.1% when using 311,725 markers vs. 60.7% when using 45,187 markers vs. 29.6% from the traditional parent average. Squared correlations with future data were slightly greater for 16 traits and slightly less for 12 with HD than with 50K evaluations. The observed 0.4 percentage point average increase in reliability was less favorable than the 0.9 expected from simulation but was similar to actual gains from other HD studies. The largest HD and 50K marker effects were often located at very similar positions. The single-breed evaluation tested here and previous single-breed or multibreed evaluations have not produced large gains. Increasing the number of HD genotypes used for imputation above 1;074 did not improve the reliability of Holstein genomic evaluations. C1 [VanRaden, P. M.; Null, D. J.; Wiggans, G. R.; Tooker, M.

Schizophyllan is commercially produced for pharmaceutical and cosmetics uses. However, the unique physical properties of schizophyllan suggest that it may have biomaterials applications. Schizophyllan is conventionally produced by submerged culture fermentation using glucose as a carbon source. This study demonstrates for the first time the efficient utilization of agricultural biomass substrates, particularly distiller's dried grains with solubles, for schizophyllan production. Sugar composition analysis, NMR, and permethylation linkage analysis confirmed that the recovered product was schizophyllan. Schizophyllan produced from agricultural residues was of a high molecular weight and exhibited solution viscosity properties similar to those of commercially produced material. Utilization of biomass substrates could reduce the cost of schizophyllan production and provide a new value-added bioproduct for integrated biorefineries of the future.

Full reproductive development may take several weeks, but initiation of this developmental response most likely occurs shortly after colony members detect when a reproductive-specific signal is missing. We investigated the early response of termite helpers to the removal of their king and queen in the basal termite species Zootermopsis nevadensis. Within 6-12 h after reproductives were removed, helpers displayed an increase in head-butting-a behavior associated with dominance in other termite species as well as in closely related roaches. The loss of just one reproductive, either the king or queen, was also sufficient to cause an increase in head-butting. We did not find evidence, however, that this response was sex-specific: males and females were equally likely to increase head-butting independent of the sex of the reproductive that was removed. Finally, we discovered that reproductive-specific compounds present on the cuticle of king and queen termites were also present in their feces, but the presence of the feces did not seem sufficient to inhibit the increased head-butting after the reproductives were removed. Collectively, these results indicate that termite workers readily detect the loss of reproductives in their colony and that they at least initially respond in a non sex-specific manner.

The moths significantly (P < 0.05) increased their ground speed over floor patterns of transverse stripes or pseudo randomly placed dots. The moths' track angles (flight path angle off the windline) decreased significantly (P < 0.05) when they flew 40 cm above the floor patterns vs. flight at 10 cm up, and they tended to steer more upwind flight (smaller course angles) at the upper, 40 cm, height compared to 10 cm up. Turn frequencies and reversal distances across the wind line were also affected by dot density. However, the interaction of small changes in flight speed, course angle, turn widths and turn frequencies are difficult to assess; I have subsumed all their affects into a simple measure of "total distance" flown by the moths by summing the length of all flight vectors analyzed for the other metrics, but no differences were found. By far, the largest change in flight was the positive orthokinetic response to increased flight height above both striped and dotted floor patterns (Fig. 2; P < 0.05), and nearly all other changes appear to be entirely due to faster moth flight with little or no changes in steering or turning patterns.

This study investigated whether C. inclusum can use chemical compounds present in H. zea scales and egg residues as kairomones to find these non-motile prey items. In a series of no- choice tests, spiders were presented with a piece of florist paper containing scales alone, scales + egg residues, or untreated controls. Next, spiders were presented with solvent extracts of either scales or eggs. Polar and non-polar solvents were used in the extractions. Contact with scales alone, scales + egg residues, and non-polar solvent extracts of both scales and eggs resulted in retention and/or induction of local searching behavior. Extracts made with polar solvents induced no apparent response, indicating that the chemostimulatory compounds are lipophilic. These results show that C. inclusum responds to kairomones left by ovipositing H. zea and use these chemical cues to detect and locate H. zea eggs.

TI Fetal Muscle-Type Nicotinic Acetylcholine Receptor Activation in TE-671 Cells and Inhibition of Fetal Movement in a Day 40 Pregnant Goat Model by Optical Isomers of the Piperidine Alkaloid Coniine SO JOURNAL OF PHARMACOLOGY AND EXPERIMENTAL THERAPEUTICS LA English DT Article ID HEMLOCK CONIUM-MACULATUM; CONGENITAL SKELETAL MALFORMATIONS; ALPHA-CONOTOXIN EI; POISON-HEMLOCK; CLEFT-PALATE; MATERNAL INGESTION; NEWBORN PIGS; TERATOGENS; LIVESTOCK; TOXICITY AB Coniine is an optically active toxic piperidine alkaloid and nicotinic acetylcholine receptor (nAChR) agonist found in poison hemlock (Conium maculatum L.). Coniine teratogenicity is hypothesized to be attributable to the binding, activation, and prolonged desensitization of fetal muscle-type nAChR, which results in the complete inhibition of fetal movement. However, pharmacological evidence of coniine actions at fetal muscle-type nAChR is lacking. The present study compared (-)-coniine, (+)-coniine, and nicotine for the ability to inhibit fetal movement in a day 40 pregnant goat model and in TE-671 cells that express fetal muscle-type nAChR. Furthermore, alpha-conotoxins (CTx) EI and GI were used to antagonize the actions of (+)- and (-)-coniine in TE-671 cells. (-)-Coniine was more effective at eliciting electrical changes in TE-671 cells and inhibiting fetal movement than was (+)-coniine, suggesting stereoselectivity by the receptor. The pyridine alkaloid nicotine did not inhibit fetal movement in a day 40 pregnant goat model, suggesting agonist specificity for the inhibition of fetal movement. Low concentrations of both CTxs potentiated the TE-671 cell response and higher concentrations of CTx EI, and GI antagonized the actions of both coniine enantiomers demonstrating concentration-dependent coagonism and selective antagonism. These results provide pharmacological evidence that the piperidine alkaloid coniine is acting at fetal muscle-type nAChR in a concentration-dependent manner.

TI Registration of 'Julie' High beta-Glucan Spring Barley SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article AB The numerous health benefits associated with the consumption of barley has resulted in U. S. Food and Drug Administration approval for the use of high beta-glucan barley in reducing the risk of cardiovascular disease. With the objective of releasing high-value food barley to meet that health claim, 'Julie' (Reg. No. CV-351, PI 665006), a two-rowed, spring, high beta-glucan barley (Hordeum vulgare L.) was developed and submitted for release in 2009 by the USDA-ARS, Aberdeen, ID, in cooperation with the University of Idaho Agricultural Experiment Station. Julie is a selection from the cross 10/'Azhul'//'CDC Alamo'. 10 is a selection from composite cross XXXII made by Dr. Tom Ramage (USDA-ARS, retired). Azhul is a six-rowed, high beta-glucan cultivar released by the USDA-ARS and the Arizona Agricultural Experiment Station and is the progenitor of most high beta-glucan cultivars and germplasm. Azhul was developed by the mutation of line 76-19-7 with diethyl sulfate. Line 76-19-7 has the pedigree CCXXXII/'Arimont'//'Westbar'. CDC Alamo, tested as HB340, has the pedigree SB85750/Azhul. Under dryland and irrigated conditions, the yield and test weight of Julie are greater than those of the currently grown high beta-glucan varieties CDC Alamo and Azhul, and Julie has a higher yield of barley beta-glucan on a per hectare basis.

No. CV-350, PI 659067), a six-row, winter hulless barley (Hordeum vulgare L.) developed and tested as VA01H-68 by the Virginia Agricultural Experiment Station, was released in May 2007. Eve was derived from the cross SC860974/VA94-42-13 using a modified bulk-breeding method. It was evaluated in the 2009-2011 Virginia Official Variety Trial in replicated tests at five to six locations. Eve had an average grain yield (3718 kg ha(-1)) that was higher than those of the hulless check cultivars Dan and Doyce. The average grain volume weight of Eve (73.8 kg hL(-1)) over the same period was higher than that of Doyce (68.9 kg hL(-1)). The head emergence of Eve is 6 d earlier than Dan and 'Thoroughbred', which is the predominant barley cultivar grown in the eastern United States. Earlier maturity is a primary factor determining whether barley or wheat (Triticum aestivum L.) is used in double-cropping systems with soybean (Glycine max L.). The grain of Eve has high starch (60.4%) and protein (10.1%) concentration. Eve is the first winter hulless barley released in the eastern United States having a high level of resistance to Fusarium head blight [FHB; caused by Fusarium graminearum (Schwabe)] and reduced accumulation of the mycotoxin deoxnivalenol in the grain. Eve's unique grain composition and resistance to FHB make it desirable as a commodity for food, feed, and ethanol production. C1 [Brooks, W. S.; Berger, G. L.; Griffey, C. A.; Thomason, W.

No. CV-116, PI 665474) peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) is a high-oleic-oil cultivar with the experimental designation TX994313 that was cooperatively developed and released by the USDA-ARS, Texas AgriLife Research, and the Oklahoma Agricultural Experiment Station in 2011. Sustainable peanut production in the southwestern United States is driven by the availability of cultivars possessing high oleic fatty-acid oil content, high yield, and superior grade. The objective of this work was to develop a high-oleic peanut cultivar with acceptable yield and superior grade potential (near or above 70%) that would increase the peanut producer's profit per hectare. Red River Runner was selected from progenies derived from a three-way cross between 'Tamrun 96', breeding line TX901639-3, and 'Sun-Oleic 95R' and cooperatively tested for several years. Red River Runner has an excellent yield and moderate tolerance to Sclerotinia blight (caused by Sclerotinia minor Jaggar). Red River Runner is similar to the existing high-oleic runner cultivar 'Tamrun OL07' in many agronomic characteristics such as yield, seed size, and weight. However, Red River Runner was released because it consistently exhibits a higher grade potential than Tamrun OL07 in some locations in Texas (averaging 5.4 points higher) and in most locations in Oklahoma (averaging 4.6 points higher); therefore in those locations, production of Red River Runner will significantly increase the crop value per hectare for peanut growers.

TI Registration of 'Jazzman-2' Aromatic Long-Grain Rice SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article AB 'Jazzman-2' (Reg. No. CV-139, PI 663188) is the second jasmine-type long-grain aromatic rice (Oryza sativa L.) cultivar, which was developed using the pedigree selection by the Rice Research Station, Louisiana State University Agricultural Center near Crowley, LA. It was approved for official release by the director of the Louisiana Agricultural Experiment Station in 2010 based on its strong aroma, slender and translucent grain, fair yield potential, and good milling quality. In 28 yield trials conducted at five Louisiana locations and in five southern rice growing states during 2006-2010, Jazzman-2 had an average main crop grain yield of 7.39 t ha(-1), which was lower than that of 'Jazzman' (7.93 t ha(-1)) and the nonaromatic check 'Cheniere' (8.98 t ha(-1)). Jazzman-2 is similar to Cheniere in plant height but is 10 cm shorter than Jazzman. The average number of days from emergence to 50% heading is 83, 85, and 87 for Jazzman-2, Cheniere, and Jazzman. Jazzman-2 has a commercially acceptable head rice yield of 639 g kg-1, which is similar to the 633 and 630 g kg(-1) of Jazzman and Cheniere. Jazzman-2 has the typical jasmine-rice cooking quality with low amylose content, low gelatinization temperature, and a very strong aroma. The average amylose content of Jazzman-2 is 14.4% compared with 15.7 and 24.2% for Jazzman and Cheniere. The average alkali spread value of Jazzman-2, Jazzman, and Cheniere is 6.0, 6.4, and 4.4. Jazzman-2 has an average 2-acetyl-pyrroline content of 833 ng g(-1), which is significantly higher than the 482 ng g(-1) of Jazzman. Naming the new cultivar Jazzman-2 is based on the fact that both Jazzman-2 and Jazzman share the similar unique cooking quality and also for branding purposes. Jazzman-2 will complement the original Jazzman by offering more choices to rice growers, processors, and consumers with its earliness, short stature, and enhanced specialty attributes. C1 [Sha, X.

CPCL 95-2287, which was released in Florida on 20 Sept. 2011, was selected from a cross of genotype CL 78-1120 x CL 78-1600 made at Clewiston, FL on 27 Dec. 1994. The female and male parents, CL 78-1120 and CL 78-1600, are proprietary genotypes of USSC. CPCL 95-2287 was released because of its high cane yield, acceptable levels of commercial recoverable sucrose on organic (muck) soils, and its resistance to brown rust (caused by Puccinia melanocephala H. & P.

Jeswiet) was released by the USDA-ARS Sugarcane Research Unit working cooperatively with the Louisiana State University Agricultural Center and the American Sugarcane League of the USA. This high-fiber sugarcane cultivar was released for use as a biofuel feedstock to fill the rising industry demand. Ho 02-113 is a progeny of the cross SES 234 x 'LCP 85-384' made in Houma, LA in 2001. The cultivar was selected at the USDA-ARS research farm in Schriever, LA, evaluated in multiple locations, and harvested from six southern Louisiana locations in six plant-cane, two first-ratoon, two second-ratoon, and two third-ratoon replicated tests. Ho 02-113 averaged 125.3 Mg ha(-1) total cane (TC) on a wet-weight basis, 12.8 Mg ha(-1) total soluble solids (TSS), 32.8 Mg ha(-1) total fiber (TF), and 45.3 Mg ha(-1) total fiber and soluble solids (TFSS). These values were significantly higher than those for the leading high-fiber sugarcane cultivar L 79-1002, which averaged 102.7 Mg ha(-1) TC, 9.6 Mg ha(-1) TSS, 27.8 Mg ha(-1) TF, and 37.4 Mg ha-1 TFSS. The cultivar is resistant to leaf scald [caused by Xanthomonas albilinenas (Ashby) Dawson] and smut (caused by Ustilago scitaminea H. and P.

No. CV-1081, PI 666125), a hard red winter wheat (Triticum aestivum L.) cultivar with experimental designation TX02A0252, was developed and released by Texas AgriLife Research in 2010. TAM 113 is an F-5-derived line from the cross TX90V6313/TX94V3724 made at Vernon, TX in 1995. Both TX90V6313 and TX94V3724 are Texas experimental lines derived from the crosses TAM 200 '' S ''/TX78A3345-V34 and U1254-1-8-1-1/'TAM 202' (PI 561933), respectively. TAM 113 is an awned, medium maturing, semidwarf wheat with white glumes. It was released primarily for its excellent grain-yield potential in both irrigated and dryland environments of the Texas High Plains; for its resistance to leaf rust (caused by Puccinia triticina Eriks.), stripe rust (caused by P. striiformis Westend.), and stem rust (caused by P. graminis Pers.: Pers f. sp. tritici Eriks. & E. Henn.); and for its good milling and exceptional bread-baking characteristics. TAM 113 has a similar area of adaptation and grain-yield potential as 'TAM 111' (PI 631352) and 'TAM 112' (PI 643143). However, compared with TAM 111, it has better leaf rust resistance and better bread-baking qualities, and compared with TAM 112, it has better resistance to leaf and stripe rusts. TAM 113, with better milling and baking characteristics and resistance to leaf, stripe, and stem rusts, will provide a good complement to other hard red winter wheat cultivars for wheat producers in the southern Great Plains.

TI 'Prosper': A High-Yielding Hard Red Spring Wheat Cultivar Adapted to the North Central Plains of the USA SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article ID PYRENOPHORA-TRITICI-REPENTIS; FUSARIUM HEAD BLIGHT; TAN SPOT; REGISTRATION; RESISTANCE AB Providing wheat (Triticum aestivum L.) growers and industry with adapted wheat cultivars with high-quality attributes is essential for maintaining wheat as a competitive crop in the spring-wheat growing region of the USA. Therefore, our breeding program aims to develop modern wheat cultivars using both traditional and modern breeding tools. 'Prosper' (Reg. No. CV-1080, PI 662387) hard red spring wheat was developed at North Dakota State University and released jointly by the North Dakota Agricultural Experiment Station and the Minnesota Agricultural Experiment Station because of its good adaptation to the spring-wheat-growing regions in the U. S. North Central Plains. However, the high yield potential of Prosper under high rainfall conditions makes it more adapted mainly to wheat-growing regions in eastern North Dakota, western Minnesota, and high-rainfall regions of neighboring states. It has high yield potential and good milling and baking properties. Gene postulation shows that Prosper has the Lr21 gene, which confers resistance to leaf rust (caused by Puccinia triticina Eriks.). However, 2011 field observations show that Prosper is susceptible to a new race that overcomes the Lr21 gene. Prosper is resistant to stem rust (caused by Puccinia graminis Per.: Pers. f. sp. tritici Eriks. & E. Henn) and moderately resistant to Fusarium head blight (FHB), or scab [caused by Fusarium graminearum Schwabe; telomorph Gibberella zeae (Schwein.) Petch].

Our objective was to develop a club wheat cultivar with resistance to stripe rust (caused by Puccinia striiformis f. sp. tritici Westend.) and strawbreaker foot rot [caused by Oculimacula yallundae Crous & W. Gams (Wallwork & Spooner) and O. acuformis (Boerema, R. Pieters & Hamers) Crous. & W. Gams] and with the end-use qualities that make club wheat a specialty product. The bulk pedigree breeding method was used to select 'Cara' (Reg. No. CV-1078, PI 643435) from the cross WA7752//WA6581/WA7217 made in 1992. Cara is a semidwarf wheat with the Rht-D1b dwarfing allele. Cara has winter hardiness equal to that of other club wheat cultivars-Bruehl, Chukar, and Coda-but less than the soft white wheat cultivars Eltan (PI 536994) or Masami (PI 634715). Cara was evaluated in multi-environment replicated plot trials in the Washington since 2003. Grain yields were equal to or better than other club and soft white cultivars in the 30- to 40-cm and the 40- to 50-cm annual precipitation zones. The milling and baking quality of Cara was equal to those of the best club wheat check cultivars. Cara is resistant to all races of stripe rust prevalent since 2001, possessing Yr17 and unknown genes for stripe rust resistance. It is also resistant to strawbreaker foot rot, possessing Pch1. Cara provides growers with an agronomically competitive cultivar with resistance to stripe rust and strawbreaker foot rot plus excellent club wheat end-use quality.

TI 'Stabilizer', a New Low-Growing Siberian Wheatgrass Cultivar for Use on Semiarid Lands SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article ID CRESTED WHEATGRASS; ESTABLISHMENT AB The USDA-ARS announces the public release of the cultivar 'Stabilizer' (Reg. No. CV-33, PI 665034) Siberian wheatgrass [Agropyron fragile (Roth) Candargy] as a low-growing, rapid-establishing revegetation grass for use on rangelands and roadsides and as a grass component in fire-strip plantings in the Intermountain West, Great Basin, and northern Great Plains regions of the western United States. Selection emphasis in Stabilizer was for seedling establishment, persistence, seed production, pubescence, and reduced forage yield. During the establishment year, Stabilizer had similar numbers of seedlings per unit area, using a frequency grid, as did the cultivar 'Vavilov II' at Guernsey, WY, Dugway, UT, Beaver, UT, Fillmore, UT, and Malta, ID; and the cultivar 'Vavilov' at King Hill, ID and Spring City, UT. Stabilizer persisted as well as Vavilov II at Guernsey, WY, Fillmore, UT, and Beaver, UT but was significantly more persistent than Vavilov II at Malta, ID. Stabilizer had significantly less dry matter yield (0.25 kg plot(-1)) at Beaver, UT than Vavilov II (0.53 kg plot(-1)) and Vavilov (0.60 kg plot(-1)). Stabilizer was genetically distinct and unique with respect to the other available Siberian wheatgrass varieties. C1 [Jensen, K. B.; Bushman, B. S.; Waldron, B. L.; Robins, J. G.; Johnson, D.

TI ND 803 Spring Wheat Germplasm Combining Resistance to Scab and Leaf Diseases with Good Agronomic and Quality Traits SO JOURNAL OF PLANT REGISTRATIONS LA English DT Article ID PYRENOPHORA-TRITICI-REPENTIS; FUSARIUM HEAD BLIGHT; TAN SPOT; REGISTRATION AB The development of adapted wheat germplasm is essential so that breeding programs can develop superior cultivars, which was the objective of this research. ND 803 is hard red spring wheat (HRSW; Triticum aestivum L.) line that was developed at North Dakota State University (NDSU) and released by the North Dakota Agricultural Experiment Station (NDAES). ND 803 (Reg. No. GP- 947, PI 665931 was derived from the ND2831/FO. 2808 cross made at NDSU in fall 1997. ND2831 ('Sumai3' [PI 481542]/'Stoa' [PI 520297]) is a hard red spring experimental line with good resistance to Fusarium head blight (FHB), or scab [caused by Fusarium graminearum Schwabe; telomorph Gibberella zeae (Schwein.) Petch] originating from 'Sumai3', which is known to possess the Fhb1 quantitative trait locus. Sumai3 is a spring wheat from China that is arguably the most widely used source of resistance to FHB in the world. Stoa is an HRSW cultivar released by NDSU in 1984. FO.2808 ('Grandin' [PI 531005]/3/IAS20*4/H567.71//'Amidon' [PI 527682]/ND674) is an HRSW line developed by the NDSU HRSW breeding program. Amidon and Grandin are HRSW cultivars released by NDAES in 1988 and 1989, respectively. IAS20*4/H567.71 is a public breeding line received from CIMMYT. ND 803 was produced from a bulk of one purified F-5:6 plot selected in 2000 at Prosper, ND. ND 803 was released because it combines good agronomic and end-use quality with resistance to both FHB and leaf diseases.

MOENCH; LESION MIMIC MUTANTS; SPARSE-BLOOM MUTANTS; CYTOLOGICAL CHARACTERISTICS; RESISTANCE GENE; INHERITANCE; RICE; CHARACTERS; EXPRESSION; PHENOTYPE AB Genetic stock collections have played an important role in shaping breeding strategies in many crops. With the advance in genomics, they are now essential tools for identifying genes underlying important agronomic traits. The objective of this work is to formally register and document the release of historical sorghum [Sorghum bicolor (L.) Moench] genetic stocks originally collected and curated by the late USDA-ARS sorghum geneticist Keith Schertz. The seeds from the original collection were revitalized at the USDA-ARS Experiment Station at Lubbock, TX in 2004 and 2006, and evaluated for phenotypic variations in 2009. The collection consists of 507 lines and accessions (Reg. No. GS-144, PI 663217 through Reg. No. GS-650, PI 663723). This collection displays significant variation in growth, developmental, and agronomic traits, such as seedling vigor, leaf/vegetative organs, reproduction, maturity, height, and grain quality. Combined with advanced genomic tools, these genetic stocks are vital resources for elucidating the fundamental pathways that make sorghum and other related grasses unusually tolerant to drought and heat stress, have moderate to low requirements for fertilizer, and highly productive under diverse environmental conditions.

TI PREPARATION AND EVALUATION OF TARA-MODIFIED PROTEINS SO JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION LA English DT Article ID OXIDIZED PHENOLIC-COMPOUNDS; GELATIN GELS; MECHANICAL-PROPERTIES; SURIMI; ACID; PRODUCTS; STRENGTH; FILMS AB Quebracho, a vegetable tannin, can be used to modify gelatin to produce a product that has been applied effectively as a filler in leather processing, as described in our previous report. In this ongoing study, another vegetable tannin, tara, is examined for its possible application in protein modification. The tara tanning substance is a gallotannin, comprised mainly of gallic acid, and is extracted from the pods of the small tara tree (caesalpinia spinosa); it is a native plant species of Peru. Advantages for using tara are that it not only gives an almost colorless product, which would be desirable in production of light colored leather, it also imparts light-fastness to the resultant leather and is a truly sustainable resource. We examined the possibility of using both tara and its main component, the polyphenolic gallic acid, as crosslinking agents for gelatin and whey protein concentrate (WPC). Protein modification parameters were developed and the results of product characterization using physicochemical analyses showed that products had improved physical properties. The molecular weight distribution indicated that the bands indicative of gelatin and whey had been altered suggesting higher molecular weight moieties. Thus, by-products from the leather and dairy industry, modified by using a sustainable resource, have the potential to be used in leather processing, specifically as fillers. C1 [Taylor, M.

TI EFFECTS OF PRETANNING PROCESSES ON COLLAGEN STRUCTURE AND REACTIVITY SO JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION LA English DT Article ID HIDE; MICROFIBRIL; STABILITY AB The cattle hide, a major byproduct of the US meat industry, is the tanner's substrate, and also the source of collagen for the food and biomaterials industries. Conversion of animal hides into leather is a multistep process that continually evolves in response to economic and environmental concerns. Processing changes are generally evaluated in terms of impact on tannery costs and quality of leather produced. Because the basis for tanning and other biomaterial applications is the stabilization of the collagen matrix, changes to the molecular characteristics of hide collagen may be expected to impact these applications. In previous studies, we began the development of protocols for production and utilization of powdered hide from specific steps in beam-house processing. In this study, the effects of pretanning processes on the structure, stability and reactivity of hide collagen with tanning materials are evaluated. The results are anticipated to assist the tanner as well as the manufacturers of collagen-based biomaterials and gelatin to better understand their substrate and changes to it that may occur when beam-house processes are altered.

The cultivation of waxy varieties is concentrated in east Asia, where there is a culinary preference for glutinous-textured foods that may have developed from ancient food processing traditions. The waxy phenotype results from mutations in the GBSSI gene, which catalyzes amylose synthesis. Broomcorn or proso millet (Panicum miliaceum L.) is one of the world's oldest cultivated cereals, which spread across Eurasia early in prehistory. Recent phylogeographic analysis has shown strong genetic structuring that likely reflects ancient expansion patterns. Broomcorn millet is highly unusual in being an allotetraploid cereal with fully waxy varieties. Previous work characterized two homeologous GBSSI loci, with multiple alleles at each, but could not determine whether both loci contributed to GBSSI function. We first tested the relative contribution of the two GBSSI loci to amylose synthesis and second tested the association between GBSSI alleles and phylogeographic structure inferred from simple sequence repeats (SSRs). We evaluated the phenotype of all known GBSSI genotypes in broomcorn millet by assaying starch composition and protein function. The results showed that the GBSSI-S locus is the major locus controlling endosperm amylose content, and the GBSSI-L locus has strongly reduced synthesis capacity. We genotyped 178 individuals from landraces from across Eurasia for the 2 GBSSI and 16 SSR loci and analyzed phylogeographic structuring and the geographic and phylogenetic distribution of GBSSI alleles. We found that GBSSI alleles have distinct spatial distributions and strong associations with particular genetic clusters defined by SSRs. The combination of alleles that results in a partially waxy phenotype does not exist in landrace populations. Our data suggest that broomcorn millet is a system in the process of becoming diploidized for the GBSSI locus responsible for grain amylose. Mutant alleles show some exchange between genetic groups, which was favored by selection for the waxy phenotype in particular regions. Partially waxy phenotypes were probably selected against-this unexpected finding shows that better understanding is needed of the human biology of this phenomenon that distinguishes cereal use in eastern and western cultures.

TI Effects of dietary polyphenols on neuroregulatory factors and pathways that mediate food intake and energy regulation in obesity SO MOLECULAR NUTRITION & FOOD RESEARCH LA English DT Review DE Hypothalamus; Metabolic syndrome; Neuropeptides; Nutrition ID ISLET AMYLOID POLYPEPTIDE; CENTRAL-NERVOUS-SYSTEM; MELANIN-CONCENTRATING HORMONE; TYPE-2 DIABETES-MELLITUS; CENTRAL NEURAL-NETWORKS; BODY-WEIGHT REGULATION; PULP PREPARATION RICH; GRAPE SEED EXTRACT; NEUROPEPTIDE-Y; INSULIN-RESISTANCE AB Polyphenols are natural substances and are enriched in vegetables, fruits, grains, bark, tea, and wine. Some polyphenols have insulin-potentiating and anti-inflammatory effects, both of which are important in obesity. Dietary supplementation with polyphenolic compounds is associated with reduced diet-induced obesity and/or metabolic syndrome in animal and human studies. Insights into mechanisms that regulate food intake and satiety have led to an increased understanding of obesity but the pathogenesis underlying obesity is lacking. Food intake is subject to a complex regulation by the hypothalamus and other brain centers including the brain stem and the hippocampus. An intricate network of interacting feedback mechanisms that involve the aforementioned neural centers along with the stomach, gut, liver, thyroid, and adipose tissue in the periphery, influence the eventual outcome of food intake and satiety. Key peripheral signals, such as leptin, insulin, and ghrelin, have been linked to hypothalamic neuropeptide systems in energy regulation. This review will examine the neural centers important in food intake, the role of various neuropeptides, and the neurohormonal influence on food intake. The potential role of polyphenols in influencing the neuroregulatory factors, the neural signaling pathways and/or the peripheral feedback mechanisms that modulate food intake will also be examined.

Here we extensively examine the genetic architecture of maize oil biosynthesis in a genome-wide association study using 1.03 million SNPs characterized in 368 maize inbred lines, including 'high-oil' lines. We identified 74 loci significantly associated with kernel oil concentration and fatty acid composition (P < 1.8 x 10(-6)), which we subsequently examined using expression quantitative trait loci (QTL) mapping, linkage mapping and coexpression analysis. More than half of the identified loci localized in mapped QTL intervals, and one-third of the candidate genes were annotated as enzymes in the oil metabolic pathway. The 26 loci associated with oil concentration could explain up to 83% of the phenotypic variation using a simple additive model. Our results provide insights into the genetic basis of oil biosynthesis in maize kernels and may facilitate marker-based breeding for oil quantity and quality.
