Here we report a high-quality draft genome sequence of the east Asia watermelon cultivar 97103 (2n = 2x = 22) containing 23,440 predicted protein-coding genes. Comparative genomics analysis provided an evolutionary scenario for the origin of the 11 watermelon chromosomes derived from a 7-chromosome paleohexaploid eudicot ancestor. Resequencing of 20 watermelon accessions representing three different C. lanatus subspecies produced numerous haplotypes and identified the extent of genetic diversity and population structure of watermelon germplasm. Genomic regions that were preferentially selected during domestication were identified. Many disease-resistance genes were also found to be lost during domestication. In addition, integrative genomic and transcriptomic analyses yielded important insights into aspects of phloem-based vascular signaling in common between watermelon and cucumber and identified genes crucial to valuable fruit-quality traits, including sugar accumulation and citrulline metabolism.

Cryptosporidium infections have a wide spectrum of clinical signs that can vary from asymptomatic to serious infection to death. In neonatal ruminants, cryptosporidiosis is considered an important disease characterised by diarrhoea and mortality. In companion animals most infections are asymptomatic but severe clinical illness has also been reported in dogs, cats and horses. In birds, three main clinical forms of cryptosporidiosis are primarily seen in naturally occurring infections, i.e. respiratory, intestinal, and renal. In reptiles, cryptosporidiosis is an emerging problem given that infections are frequently chronic and lethal. Molecular tools have been developed to detect and differentiate Cryptosporidium at the species/genotype and subtype levels. The use of those tools has led to a more in-depth understanding of the genetic diversity of Cryptosporidium which plays an important role in the diverse clinical presentations of cryptosporidiosis. This review presents an overview of the current knowledge on clinical cryptosporidiosis in livestock, pets, and other animals.

TI PIECE: a database for plant gene structure comparison and evolution SO NUCLEIC ACIDS RESEARCH LA English DT Article ID MULTIPLE SEQUENCE ALIGNMENT; PROTEIN FAMILIES; INTRON EVOLUTION; GENOMICS; GAIN; CONSERVATION; EUKARYOTES; RESOURCE; DNA AB Gene families often show degrees of differences in terms of exon-intron structures depending on their distinct evolutionary histories. Comparative analysis of gene structures is important for understanding their evolutionary and functional relationships within plant species. Here, we present a comparative genomics database named PIECE (http://wheat.pw.usda.gov/piece) for Plant Intron and Exon Comparison and Evolution studies. The database contains all the annotated genes extracted from 25 sequenced plant genomes. These genes were classified based on Pfam motifs. Phylogenetic trees were pre-constructed for each gene category. PIECE provides a user-friendly interface for different types of searches and a graphical viewer for displaying a gene structure pattern diagram linked to the resulting bootstrapped dendrogram for each gene family. The gene structure evolution of orthologous gene groups was determined using the GLOOME, Exalign and GECA software programs that can be accessed within the database. PIECE also provides a web server version of the software, GSDraw, for drawing schematic diagrams of gene structures. PIECE is a powerful tool for comparing gene sequences and provides valuable insights into the evolution of gene structure in plant genomes.

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

To evaluate the potential physiological responses of sugar maple (Acer saccharum Marsh.) to a reduced snowpack, we measured root injury, foliar cation and carbohydrate concentrations, woody shoot carbohydrate levels, and terminal woody shoot lengths of trees in a snow manipulation experiment in New Hampshire, USA. Snow was removed from treatment plots for the first 6 weeks of winter for two consecutive years, resulting in lower soil temperatures to a depth of 50 cm for both winters compared to reference plots with an undisturbed snowpack. Visibly uninjured roots from trees in the snow removal plots had significantly higher (but sub-lethal) levels of relative electrolyte leakage than trees in the reference plots. Foliar calcium: aluminum (Al) molar ratios were significantly lower, and Al concentrations were significantly higher, in trees from snow removal plots than trees from reference plots. Snow removal also reduced terminal shoot growth and increased foliar starch concentrations. Our results are consistent with previous research implicating soil freezing as a cause of soil acidification that leads to soil cation imbalances, but are the first to show that this translates into altered foliar cation pools, and changes in soluble and structural carbon pools in trees. Increased soil freezing due to a reduced snowpack could exacerbate soil cation imbalances already caused by acidic deposition, and have widespread implications for forest health in the northeastern USA.

TI Influence of a non-copper algicide on the cyanobacterium, Nostoc spongiaeforme, and the green alga, Hydrodictyon reticulatum, in field and laboratory experiments SO PADDY AND WATER ENVIRONMENT LA English DT Article DE Algae management; Algicide; Rice straw; Microbial degradation; Hydrothol 191 ID CALIFORNIA RICE FIELDS; TEMPERATURE; GROWTH AB Cyanobacteria and algae grow in California rice fields where they form large mats that may smother seedlings or cause them to dislodge, resulting in reduced rice stand establishment and potential yield loss. The most troublesome species of cyanobacteria is Nostoc spongiaeforme. It is very difficult to control using currently accepted methods, i.e., aerial applications of copper sulfate. A non-copper algicide, the mono (N,N-dimethylalkylamine) salt of endothall has been suggested as an alternative method for controlling nuisance cyanobacterial and algal growths in California rice fields. The purpose of the experiments described here was to evaluate the effect of the mono (N,N-dimethylalkylamine) salt of endothall on growth of N. spongiaeforme and the green alga, Hydrodictyon reticulatum. In laboratory experiments, the mono (N,N-dimethylalkylamine) salt of endothall reduced N. spongiaeforme growth at 0.3 mg L-1. This effect was removed when rice straw was added to the growth medium, indicating that the rice straw may have introduced bacteria capable of degrading the mono (N,N-dimethylalkylamine) salt of endothall. In outdoor experiments, which used rice field water containing decomposing rice straw, the mono (N,N-dimethylalkylamine) salt of endothall concentrations between 0 and 5 mg L-1 had little effect on N. spongiaeforme. In contrast, H. reticulatum exhibited injury symptoms at 1 mg L-1 or greater. However, H. reticulatum recovered by the end of the 7-day exposure. It is not clear how this algicide will be useful in the management of N. spongiaeforme or H. reticulatum in California rice fields.

Heat treatment eliminates 'Candidatus Liberibacter asiaticus' from infected citrus trees under controlled conditions. Phytopathology 13:15-22. Huanglongbing (HLB) is one of the most destructive diseases of citrus worldwide. The three known causal agents of HLB are species of alpha-proteobacteria: 'Candidatus Liberibacter asiaticus', 'Ca. L. africanus', and 'Ca. L. americanus'. Previous studies have found distinct variations in temperature sensitivity and tolerance among these species. Here, we describe the use of controlled heat treatments to cure HLB caused by 'Ca. L. asiaticus', the most prevalent and heat-tolerant species. Using temperature-controlled growth chambers, we evaluated the time duration and temperature required to suppress or eliminate the 'Ca. L. asiaticus' bacterium in citrus, using various temperature treatments for time periods ranging from 2 days to 4 months. Results of quantitative polymerase chain reaction (qPCR) after treatment illustrate significant decreases in the 'Ca. L. asiaticus' bacterial titer, combined with healthy vigorous growth by all surviving trees. Repeated qPCR testing confirmed that previously infected, heat-treated plants showed no detectable levels of 'Ca. L. asiaticus', while untreated control plants remained highly infected. Continuous thermal exposure to 40 to 42 degrees C for a minimum of 48 h was sufficient to significantly reduce titer or eliminate 'Ca. L. asiaticus' bacteria entirely in HLB-affected citrus seedlings. This method may be useful for the control of 'Ca. Liberibacter'-infected plants in nursery and greenhouse settings.

Membrane-based oligonucleotide array developed from multiple markers for the detection of many Phytophthora species. Phytopathology 103:43-54. Most Phytophthora spp. are destructive plant pathogens; therefore, effective monitoring and accurate early detection are important means of preventing potential epidemics and outbreaks of diseases. In the current study, a membrane-based oligonucleotide array was developed that can detect Phytophthora spp. reliably using three DNA regions; namely, the internal transcribed spacer (ITS), the 5' end of cytochrome c oxidase 1 gene (cox1), and the intergenic region between cytochrome c oxidase 2 gene (cox2) and cox1 (cox2-1 spacer). Each sequence data set contained approximate to 250 sequences representing 98 described and 15 undescribed species of Phytophthora. The array was validated with 143 pure cultures and 35 field samples. Together, nonrejected oligonucleotides from all three markers have the ability to reliably detect 82 described and 8 undescribed Phytophthora spp., including several quarantine or regulated pathogens such as Phytophthora ramorum. Our results showed that a DNA array containing signature oligonucleotides designed from multiple genomic regions provided robustness and redundancy for the detection and differentiation of closely related taxon groups. This array has the potential to be used as a routine diagnostic tool for Phytophthora spp. from complex environmental samples without the need for extensive growth of cultures.

TI Molecular Characterization of the Fatty Alcohol Oxidation Pathway for Wax-Ester Mobilization in Germinated Jojoba Seeds SO PLANT PHYSIOLOGY LA English DT Article ID SJOGREN-LARSSON-SYNDROME; ALDEHYDE-DEHYDROGENASE GENES; ARABIDOPSIS-THALIANA; ENDOPLASMIC-RETICULUM; MEMBRANE-PROTEINS; GOLGI-APPARATUS; PLANTS; CLONING; OIL; BIOSYNTHESIS AB Jojoba (Simmondsia chinensis) is the only plant species known to use liquid wax esters (WEs) as a primary seed storage reserve. Upon germination, WE hydrolysis releases very-long-chain fatty alcohols, which must be oxidized to fatty acids by the sequential action of a fatty alcohol oxidase (FAO) and a fatty aldehyde dehydrogenase (FADH) before they can be beta-oxidized. Here, we describe the cloning and characterization of genes for each of these two activities. Jojoba FAO and FADH are 52% and 68% identical to Arabidopsis (Arabidopsis thaliana) FAO3 and ALDH3H1, respectively. The genes are expressed most strongly in the cotyledons of jojoba seedlings following germination, but transcripts can also be detected in vegetative tissues. Proteomic analysis indicated that the FAO and FADH proteins can be detected on wax bodies, but they localized to the endoplasmic reticulum when they were expressed as amino-terminal green fluorescent protein fusions in tobacco (Nicotiana tabacum) leaves. Recombinant jojoba FAO and FADH proteins are active on very-long-chain fatty alcohol and fatty aldehyde substrates, respectively, and have biochemical properties consistent with those previously reported in jojoba cotyledons. Coexpression of jojoba FAO and FADH in Arabidopsis enhanced the in vivo rate of fatty alcohol oxidation more than 4-fold. Taken together, our data suggest that jojoba FAO and FADH constitute the very-long-chain fatty alcohol oxidation pathway that is likely to be necessary for efficient WE mobilization following seed germination.

TI Comparative Analysis of Syntenic Genes in Grass Genomes Reveals Accelerated Rates of Gene Structure and Coding Sequence Evolution in Polyploid Wheat SO PLANT PHYSIOLOGY LA English DT Article ID MESSENGER-RNA DECAY; HEXAPLOID WHEAT; NUCLEOTIDE SUBSTITUTION; BRACHYPODIUM-DISTACHYON; PHYLOGENETIC ANALYSIS; DUPLICATE GENES; PLANT GENOMES; ORYZA-SATIVA; BREAD WHEAT; EXPRESSION AB Cycles of whole-genome duplication (WGD) and diploidization are hallmarks of eukaryotic genome evolution and speciation. Polyploid wheat (Triticum aestivum) has had a massive increase in genome size largely due to recent WGDs. How these processes may impact the dynamics of gene evolution was studied by comparing the patterns of gene structure changes, alternative splicing (AS), and codon substitution rates among wheat and model grass genomes. In orthologous gene sets, significantly more acquired and lost exonic sequences were detected in wheat than in model grasses. In wheat, 35% of these gene structure rearrangements resulted in frame-shift mutations and premature termination codons. An increased codon mutation rate in the wheat lineage compared with Brachypodium distachyon was found for 17% of orthologs. The discovery of premature termination codons in 38% of expressed genes was consistent with ongoing pseudogenization of the wheat genome. The rates of AS within the individual wheat subgenomes (21%-25%) were similar to diploid plants. However, we uncovered a high level of AS pattern divergence between the duplicated homeologous copies of genes. Our results are consistent with the accelerated accumulation of AS isoforms, nonsynonymous mutations, and gene structure rearrangements in the wheat lineage, likely due to genetic redundancy created by WGDs. Whereas these processes mostly contribute to the degeneration of a duplicated genome and its diploidization, they have the potential to facilitate the origin of new functional variations, which, upon selection in the evolutionary lineage, may play an important role in the origin of novel traits.

C. ribicola causes white pine blister rust and has resulted in a dramatic reduction of native white pines across North America. Quantitative disease resistance (QDR) is a highly desirable trait screened in breeding programs for durable resistance against C. ribicola. Along with phenotyping on a collection of germplasms, we analyzed PmAMP1 transcript and protein expression and re-sequenced the full-length gene including its promoter region. A mixed linear model was used to identify the association of single nucleotide polymorphisms (SNPs) with accumulated protein and stem QDR levels. Among 16 PmAMP1 SNPs identified in the present study, we found an association of protein levels with 6 SNPs (P < 0.05), including 2 in the 5'-untranslated region (UTR), 3 in the open reading frame (ORF) region with 2 nonsynonymous SNPs, and 1 SNP in the 3'-UTR. Another set of six SNPs was associated with stem QDR levels (P < 0.05), with one localized in the promoter region and the other five in the ORF region with four nonsynonymous changes, suggesting that multiple isoforms may have antifungal activity to differing degrees. Of three common PmAMP1 haplotypes, the trees with haplotype 2 showed high QDR levels with moderate protein abundance while those trees with haplotype 3 exhibited low QDR levels in the susceptible range and the lowest level of protein accumulation. Thus, an association of gene variations with protein abundance and resistance-related traits may facilitate elucidation of physiological contribution of PmAMP1 to host resistance.

This frequently involves conspicuous changes in the abundance of one species (e.g., an oubreaking pest or keystone species). Alternate attractors in population dynamics could explain switches between low and high levels of abundance, and could underlie some cases of regime shifts in ecosystems; this longstanding theoretical possibility has been difficult to test in nature. We compared the ability of an alternate attractors model versus two competing models to explain population fluctuations in the tree-killing bark beetle, Dendroctonus frontalis. Frequency distributions of abundance were distinctly bimodal, a prediction of the alternate attractors model, strongly indicating the lack of a single, noisy equilibrium. Time series abundance data refuted the existence of strong delayed density-dependence or nonlinearities, as required by the endogenous cycles model. The model of alternate attractors was further supported by the existence of positive density-dependence at intermediate beetle abundances. Experimental manipulations show that interactions with competitors and shared enemies could create a locally stable equilibrium in small populations of D. frontalis. High variation among regions and years in the abundance of predators and competitors could permit switches between alternate states. Dendroctonus frontalis now provides the strongest case that we know of for alternate attractors in natural population dynamics. The accompanying demographic instability appears to underlie spatially extensive outbreaks that have lasting impacts on forest ecosystems. Understanding feedbacks in populations with alternate attractors can help to identify thresholds underlying regime shifts, and potentially manage them to avoid undesirable impacts.

These maps are more valuable to the scientific community and land managers when the accuracy of their classifications has been assessed. Here, we assessed the accuracy of a map of forest disturbance in the watersheds of lake Superior and Lake Michigan based on an improved version of the Vegetation Change Tracker algorithm (VCTw). We constructed a probability-based sampling design using two stages of sampling with stratification at each stage. Results are presented for the portion of the map within the U.S. as well as separately for the U.S. portion of Lake Superior's watershed and for lake Michigan's watershed. We also present estimates and standard errors of the percent cover for each land cover class that incorporate both the map's data and our sample data. The overall accuracy for the U.S. portion of the map is estimated to be 91% with a standard error of 0.8%. We discuss the relative strengths of the VCTw algorithm as well as the dependence of such an algorithm's success on the characteristics of the landscape being mapped. Published by Elsevier Inc.

The probability-based (design-based) statistical estimators traditionally used by NFIs to calculate estimates are generally unbiased and entail only limited computational complexity. However, these estimators often do not produce sufficiently precise estimates for areas with small sample sizes. Model-based estimators may overcome this disadvantage, but they also may be biased and estimation of variances may be computationally intensive. For a minor region within Hedmark County, Norway, the study objective was to compare estimates of mean forest growing stock volume per unit area obtained using probability- and model-based estimators. Three of the estimators rely to varying degrees on maps that were constructed using a nonlinear logistic regression model, forest inventory data, and lidar data. For model-based estimators, methods for evaluating quality of fit of the models and reducing the computational intensity were also investigated. Three conclusions were drawn: the logistic regression model exhibited no serious lack of fit to the data; estimators enhanced using maps produced greater precision than estimates based on only the plot observations; and third, model-based synthetic estimators benefit from sample sizes for larger areas when applied to smaller subsets of the larger areas.

Seven bales of pre-cleaned greige (non-bleached) cotton were procured from a US cotton producer and ginner. Each bale primarily had only one particular fiber quality parameter (e. g., length, length uniformity, micronaire, or strength) as a significant variable of interest, while other metrics remained subdued to the most practically possible extent. The fiber stock from each separate bale was processed into a lightly needlepunched substrate/fabric and then uniformly converted into a hydroentangled nonwoven fabric structure of the same nominal weight. All of the fibers and fabrics involved in the study were analyzed for their quality attributes. Although this study did not reveal any clear-cut, significant effects (obvious relations or correlations) of the fiber quality variables/metrics investigated, for the first time ever new information has been given that may be useful in the selection of optimally economical cotton for the production of cotton-based nonwoven fabrics for certain applications. At the minimum, this study has demonstrated that, unlike in traditional yarn-based textile processing, the greige cotton lint(s) of (typically) varied fiber metrics could be satisfactorily processed into viable nonwoven fabrics of acceptable physical and mechanical properties, as determined by standard test methods and procedures.

TI Molecular markers associated with the immature fiber (im) gene affecting the degree of fiber cell wall thickening in cotton (Gossypium hirsutum L.) SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID GENOME STRUCTURE; MAP; MUTANT; SSR AB Cotton fiber fineness and maturity measured indirectly as micronaire (MIC) are important properties of determining fiber grades in the textile market. To understand the genetic control and molecular mechanisms of fiber fineness and maturity, we studied two near isogenic lines, Gossypium hirsutum, Texas Marker-1 wild type (TM-1) and immature fiber (im) mutant showing a significant difference in MIC values. The fibers from im mutant plants were finer and less mature with lower MIC values than those from the recurrent parent, TM-1. A comprehensive fiber property analysis of TM-1 and im mutant showed that the lower MIC of fibers in im mutant was due to the lower degree of fiber cell wall thickening as compared to the TM-1 fibers. Using an F-2 population comprising 366 progenies derived from a cross between TM-1 and im mutant, we confirmed that the immature fiber phenotype present in a mutant plant was controlled by one single recessive gene im. Furthermore, we identified 13 simple sequence repeat markers that were closely linked to the im gene located on chromosome 3. Molecular markers associated with the im gene will lay the foundation to further investigate genetic information required for improving cotton fiber fineness and maturity.

SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID MILDEW PLASMOPARA-HALSTEDII; MARKER-ASSISTED SELECTION; DOWNY MILDEW; DISEASE-RESISTANCE; PUCCINIA-HELIANTHI; CULTIVATED SUNFLOWER; PL5/PL8 LOCUS; NORTH-DAKOTA; REGISTRATION; GERMPLASM AB Sunflower production in North America has recently suffered economic losses in yield and seed quality from sunflower rust (Puccinia helianthi Schwein.) because of the increasing incidence and lack of resistance to new rust races. RHA 464, a newly released sunflower male fertility restorer line, is resistant to both of the most predominant and most virulent rust races identified in the Northern Great Plains of the USA. The gene conditioning rust resistance in RHA 464 originated from wild Helianthus annuus L., but has not been molecularly marked or determined to be independent from other rust loci. The objectives of this study are to identify molecular markers linked to the rust resistance gene and to investigate the allelism of this gene with the unmapped rust resistance genes present in HA-R6, HA-R8 and RHA 397. Virulence phenotypes of seedlings for the F-2 population and F-2:3 families suggested that a single dominant gene confers rust resistance in RHA 464, and this gene was designated as R (12) . Bulked segregant analysis identified ten markers polymorphic between resistant and susceptible bulks. In subsequent genetic mapping, the ten markers covered 33.4 cM of genetic distance on linkage group 11 of sunflower. A co-dominant marker CRT275-11 is the closest marker distal to R (12) with a genetic distance of 1.0 cM, while ZVG53, a dominant marker linked in the repulsion phase, is proximal to R (12) with a genetic distance of 9.6 cM. The allelism test demonstrated that R (12) is not allelic to the rust resistance genes in HA-R6, HA-R8 and RHA 397, and it is also not linked to any previously mapped rust resistance genes. Discovery of the R (12) novel rust resistance locus in sunflower and associated markers will potentially support the molecular marker-assisted introgression and pyramiding of R (12) into sunflower breeding lines.

TI Interspecific chromosomal effects on agronomic traits in Gossypium hirsutum by AD analysis using intermated G-barbadense chromosome substitution lines SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID UPLAND COTTON CULTIVARS; VARIANCE-COMPONENTS; FIBER QUALITY; GENETIC VARIANCE; IMPROVEMENT; GERMPLASM; YIELD; INTROGRESSION; ENVIRONMENTS; TOPCROSSES AB The untapped potential of the beneficial alleles from Gossypium barbadense L. has not been well utilized in G. hirsutum L. (often referred to as Upland cotton) breeding programs. This is primarily due to genomic incompatibility and technical challenges associated with conventional methods of interspecific introgression. In this study, we used a hypoaneuploid-based chromosome substitution line as a means for systematically introgressing G. barbadense doubled-haploid line '3-79' germplasm into a common Upland genetic background, inbred 'Texas marker-1' ('TM-1'). We reported on the chromosomal effects, lint percentage, boll weight, seedcotton yield and lint yield in chromosome substitution CS-B (G. barbadense L.) lines. Using an additive-dominance genetic model, we studied the interaction of alleles located on two alien substituted chromosomes versus one alien substituted chromosome using a partial diallel mating design of selected CS-B lines (CS-B05sh, CS-B06, CS-B09, CS-B10, CS-B12, CS-B17 and CS-B18). Among these parents, CS-B09 and CS-B10 were reported for the first time. The donor parent 3-79, had the lowest additive effect for all of the agronomic traits. All of the CS-B lines had significant additive effects with boll weight and lint percentage. CS-B10 had the highest additive effects for lint percentage, and seedcotton and lint yield among all of the lines showing a transgressive genetic mode of inheritance for these traits. CS-B09 had greater additive genetic effects on lint yield, while CS-B06, CS-B10 and CS-B17 had superior additive genetic effects on both lint and seedcotton yield compared to TM-1 parent. The 3-79 line had the highest dominance effects for boll weight (0.513 g) and CS-B10 had the lowest dominance effect for boll weight (-0.702). Some major antagonistic genetic effects for the agronomic traits were present with most of the substituted chromosomes and chromosome arms, a finding suggested their recalcitrance to conventional breeding efforts. The results revealed that the substituted chromosomes and arms of 3-79 carried some cryptic beneficial alleles with potential to improve agronomic traits including yield, whose effects were masked at the whole genome level in 3-79.

Merr.] oil typically contains 2-4 % stearic acid. Seed oil with 20 % stearic acid would be useful for solid fat applications, both for its cooking properties and health benefits. Breeding lines with high stearic acid have been developed, but many suffer from agronomic problems. This study identifies a new source of high stearic acid, determines its relationship with another high stearic locus and presents molecular markers for it is use in breeding. TCJWB03-806-7-19, a 'Holladay' mutant with high stearic acid, was crossed to two FAM94-41-derived lines that contained a point mutation in a seed-specific isoform of a Delta 9-stearoyl-acyl carrier protein-desaturase (SACPD-C). Fatty acid analysis was performed over two growing seasons with F (2)-derived lines and transgressive segregation for stearic acid content was observed. Sequencing of SACPD isoforms in TCJWB03-806-7-19 revealed the deletion of an 'A' nucleotide in exon 3 of SACPD-B, which results in a protein whose final 28 amino acids are predicted to differ from Williams 82 SACPD-B. Sorting intolerant from tolerant (SIFT) analysis revealed that this frameshift mutation may affect SACPD-B protein function. Allele-specific genotyping for the SACPD-C point mutation and SACPD-B nucleotide deletion was performed in both populations. Additive effects and R (2) for stearic acid were +3.3 and 0.55 for SACPD-C and +1.9 and 0.19 for SACPD-B. Average stearic acid in lines homozygous for both mutations was 14.6 %. This SACPD-B mutation represents a novel high stearic allele. C1 [Ruddle, Paul, II; Whetten, Rebecca; Cardinal, Andrea] N Carolina State Univ, Dept Crop Sci, Raleigh, NC 27695 USA.

TI High Polyacrylamide Application Rates Do Not Affect Eubacterial Structural Diversity SO WATER AIR AND SOIL POLLUTION LA English DT Article DE Anionic polyacrylamide; DNA; Amplicon length heterogeneity; Bacterial diversity ID FURROW-IRRIGATION; REDUCE EROSION; WASTE-WATER; SOIL; MICROORGANISMS; DEGRADATION; ACRYLAMIDE; RUNOFF; INFILTRATION; ADDITIVES AB Anionic polyacrylamide (PAM) is a linear, water-soluble anionic polymer that is widely used for erosion control and water quality protection. There has been an issue whether this formulation could possibly have negative effects on soil microbial diversity by altering microbial binding to soil particles or to one another and thus restricting their mobility and role in carbon and nutrient cycling. We conducted an 8-year study annually applying ultra-high rates of PAM to soil and then monitored impacts on soil bacterial diversity. In July and August, we measured active soil bacterial and fungal biomass and microbial diversity in soils receiving 0 (control), 2,691, and 5,382 kg active ingredient PAMha(-1). Active microbial biomass in soil was 19-33 % greater in the untreated control than soil treated with 2,691 or 5,382 kg of active ingredient PAMha(-1). Active bacterial biomass in soil was 21-31 % greater in the control treatment than in soil treated with 2,691 or 5,382 kg of active ingredient PAMha-1 in August, but not July. Active fungal biomass in soils was 38-50 % greater in the control treatment than soil treated with 2,691 or 5,382 kg of active ingredient PAMha(-1) in July, but not August. Molecular methods were used to access the bacterial diversity, richness, and evenness in an agricultural soil that received 0 (control), 2,691, and 5,382 kg of active ingredient PAMha(-1). We found that although soil receiving these massive PAM application rates and prolonged exposure may reduce active bacterial and fungal biomass, PAM application did not substantially or consistently affect bacterial structural diversity, richness, or evenness in this agricultural soil.

TI A STELLA Model to Estimate Soil CO2 Emissions from a Short-Rotation Woody Crop SO WATER AIR AND SOIL POLLUTION LA English DT Article DE CO2 emission; Short-rotation woody crop; Soil temperature; STELLA model ID GLOBAL CLIMATE MODEL; MICROBIAL BIOMASS; SURFACE; TEMPERATURE; TRANSPORT; ECOSYSTEM; DYNAMICS; GROWTH; OXYGEN AB The potential for climatic factors as well as soil-plant-climate interactions to change as a result of rising levels of atmospheric CO2 concentration is an issue of increasing international environmental concern. Agricultural and forest practices and managements may be important contributors to mitigating elevated atmospheric CO2 concentrations. A computer model was developed using the Structural Thinking and Experiential Learning Laboratory with Animation (STELLA) software for soil CO2 emissions from a short-rotation woody crop as affected by soil water and temperature regimes, root and microbial respiration, and surficial processes such as rainfall, irrigation, and evapotranspiration. The resulting model was validated with good agreement between the model predictions and the experimental measurements prior to its applications. Two scenarios were then chosen to estimate both diurnal and annual soil CO2 emissions from a 1-ha mature cottonwood plantation as affected by soil temperature, soil (i.e., root and microbial) respiration, and irrigation. The simulation resulted in typical diurnal soil respiration and CO2 emission patterns, with increases from morning to early afternoon and decreases from early afternoon to midnight. This pattern was driven by diurnal soil temperature variations, indicating that soil temperature was the main influence on soil respiration and CO2 efflux into the atmosphere. Our simulations further revealed that the average seasonal soil respiration rate in summer was 1.6 times larger than in winter, whereas the average seasonal CO2 emission rate in summer was 1.77 times larger than in winter. Characteristic annual variation patterns for soil respiration and CO2 emission also were modeled, with both increasing from January 1 through June 30 followed by steady declines from September 1 through December 31. These results suggest that the STELLA model developed is a useful tool for estimating soil CO2 emission from a short-rotation woody crop plantation.

The goal of this research was to apply the Lavras Simulation of Hydrology (LASH model) to a Brazilian tropical watershed dominated by Oxisols, to estimate maximum, minimum and mean stream flows for both current land-use ("scenario 1") and other regional trend land-use scenarios ("scenario 2"aEuro"pasture into eucalyptus; and "scenario 3"aEuro"eucalyptus into pasture). This model is a continuous, distributed and semi-conceptual model for simulation of different hydrological components on a daily basis. The model had a good performance with respect to the "scenario 1", resulting in Nash-Sutcliffe coefficients equal to 0.81, 0.82 and 0.98 for minimum, maximum and mean discharges, respectively. When "scenario 2" was simulated, it was found that minimum, mean and maximum stream flows had their values reduced in average by 7.39 %, 13.84 % and 20.38 %, respectively. On the contrary, it was observed in "scenario 3" an increase in average by 0.23 %, 0.44 % and 1.19 % for minimum, mean and maximum stream flows, respectively. With respect to water yield, scenario 2 resulted in a mean reduction of 119 mm, whereas for scenario 3 the difference was not so pronounced in relation to the current land use. Results obtained in scenario 2 are troublesome since this watershed drains into an important regional Hydroelectric Power Plant Reservoir and this approach needs to be considered by the Minas Gerais State electric energy company for its planning strategies for the future.

Objective Test the feasibility of Helping HAND (Healthy Activity and Nutrition Directions), an obesity intervention for 5- to 8-year-old children in primary care clinics. Methods A randomized controlled pilot study of Helping HAND, a 6-month intervention, targeted children with body mass index 85-99% tile and their parents. Intervention group attended monthly sessions and self-selected child behaviours and parenting practices to change. Control group received regular paediatric care and was wait-listed for Helping HAND. Session completion, participant satisfaction, child anthropometrics, dietary intake, physical activity, TV viewing and behaviour-specific parenting practices were measured pre and post intervention. Results Forty parent-child dyads enrolled: 82.5% were Hispanic, 80% had a girl and 65% reported income <=$ 30 000/year. There was 20% attrition from Helping HAND (attended <4/6 sessions). Families self-selected 4.35 (SD 1.75) behaviours to target during the 6-month programme and each of the seven behaviours was selected by 45-80% of the families. There were no between group differences in the child's body mass index z-score, dietary intake or physical activity post intervention. Intervention group viewed 14.9 (SE 2.3) h/week of TV post intervention versus control group 23.3 (SE 2.4) h/week (P < 0.05). Conclusion Helping HAND is feasible, due to low attrition, good programme attendance, and clinically relevant improvements in some child and parenting behaviours. C1 [O'Connor, T.

TI Fitting distributions to microbial contamination data collected with an unequal probability sampling design SO JOURNAL OF APPLIED MICROBIOLOGY LA English DT Article DE maximum likelihood estimation; risk assessment; sample design ID MODEL-BASED INFERENCE; WEIGHTED DISTRIBUTIONS; ESCHERICHIA-COLI; BEEF; SALMONELLA AB Aims The fitting of statistical distributions to microbial sampling data is a common application in quantitative microbiology and risk assessment applications. An underlying assumption of most fitting techniques is that data are collected with simple random sampling, which is often times not the case. This study develops a weighted maximum likelihood estimation framework that is appropriate for microbiological samples that are collected with unequal probabilities of selection. Methods and Results A weighted maximum likelihood estimation framework is proposed for microbiological samples that are collected with unequal probabilities of selection. Two examples, based on the collection of food samples during processing, are provided to demonstrate the method and highlight the magnitude of biases in the maximum likelihood estimator when data are inappropriately treated as a simple random sample. Conclusions Failure to properly weight samples to account for how data are collected can introduce substantial biases into inferences drawn from the data. Significance and Impact of the Study The proposed methodology will reduce or eliminate an important source of bias in inferences drawn from the analysis of microbial data. This will also make comparisons between studies and the combination of results from different studies more reliable, which is important for risk assessment applications. C1 [Williams, M. S.; Ebel, E.

TI Microbial interactions associated with secondary cucumber fermentation SO JOURNAL OF APPLIED MICROBIOLOGY LA English DT Article DE Clostridium; Enterobacter; oxidative yeasts; secondary cucumber fermentation; spoilage lactic acid bacteria ID LACTIC-ACID BACTERIA; SODIUM-CHLORIDE; SPOILAGE; YEASTS; CLOSTRIDIUM; GROWTH; OXYGEN; MODEL; PH AB Aims To evaluate the interaction between selected yeasts and bacteria and associate their metabolic activity with secondary cucumber fermentation. Methods and Results Selected yeast and bacteria, isolated from cucumber secondary fermentations, were inoculated as single and mixed cultures in a cucumber juice model system. Our results confirmed that during storage of fermented cucumbers and in the presence of oxygen, spoilage yeasts are able to grow and utilize the lactic and acetic acids present in the medium, which results in increased brine pH and the chemical reduction in the environment. These conditions favour opportunistic bacteria that continue the degradation of lactic acid. Lactobacillus buchneri, Clostridium bifermentans and Enterobacter cloacae were able to produce acetic, butyric and propionic acids, respectively, when inoculated in the experimental medium at pH 4.6. Yeast and bacteria interactions favoured the survival of Cl. bifermentans and E. cloacae at the acidic pH typical of fermented cucumbers (3.2), but only E. cloacae was able to produce a secondary product. Conclusions The methodology used in this study confirmed that a complex microbiota is responsible for the changes observed during fermented cucumber secondary fermentation and that certain microbial interactions may be essential for the production of propionic and butyric acids. Significance and Impact of the Study Understanding the dynamics of the development of secondary cucumber fermentation aids in the identification of strategies to prevent its occurrence and economic losses for the pickling industry.

In the current study, the 11 Arabidopsis ZIP family members not yet well characterized were first screened for their ability to complement four yeast mutants defective in Zn, Fe, Mn, or Cu uptake. Six of the Arabidopsis ZIP genes complemented a yeast Zn uptake-deficient mutant, one was able partially to complement a yeast Fe uptake-deficient mutant, six ZIP family members complemented an Mn uptake-deficient mutant, and none complemented the Cu uptake-deficient mutant. AtZIP1 and AtZIP2 were then chosen for further study, as the preliminary yeast and in planta analysis suggested they both may be root Zn and Mn transporters. In yeast, AtZIP1 and AtZIP2 both complemented the Zn and Mn uptake mutants, suggesting that they both may transport Zn and/or Mn. Expression of both genes is localized to the root stele, and AtZIP1 expression was also found in the leaf vasculature. It was also found that AtZIP1 is a vacuolar transporter, while AtZIP2 is localized to the plasma membrane. Functional studies with Arabidopsis AtZIP1 and AtZIP2 T-DNA knockout lines suggest that both transporters play a role in Mn (and possibly Zn) translocation from the root to the shoot. AtZIP1 may play a role in remobilizing Mn from the vacuole to the cytoplasm in root stellar cells, and may contribute to radial movement to the xylem parenchyma. AtZIP2, on the other hand, may mediate Mn (and possibly Zn) uptake into root stellar cells, and thus also may contribute to Mn/Zn movement in the stele to the xylem parenchyma, for subsequent xylem loading and transport to the shoot.

In recent years, there has been an explosion of information on this topic and molecular biology has provided new and exciting opportunities to better understand the genes involved in cold adaptation, freezing response and environmental stress in general. Despite an exponential increase in our understanding of freezing tolerance, understanding cold hardiness in a manner that allows one to actually improve this trait in economically important crops has proved to be an elusive goal. This is partly because of the growing recognition of the complexity of cold adaptation. The ability of plants to adapt to and survive freezing temperatures has many facets, which are often species specific, and are the result of the response to many environmental cues, rather than just low temperature. This is perhaps underappreciated in the design of many controlled environment experiments resulting in data that reflects the response to the experimental conditions but may not reflect actual mechanisms of cold hardiness in the field. The information and opinions presented in this report are an attempt to illustrate the many facets of cold hardiness, emphasize the importance of context in conducting cold hardiness research, and pose, in our view, a few of the critical questions that still need to be addressed.

Molecular analysis of a Plum pox virus W isolate in plum germplasm hand carried into the USA from the Ukraine shows a close relationship to a Latvian isolate. Plant Dis. 97:44-52. Four of 19 Prunus germplasm accessions hand carried from the Ukraine into the United States without authorization were found to be infected with Plum pox virus (PPV). Of the three isolates characterized, isolates UKR 44189 and UKR 44191 were confirmed to be isolates of PPV strain W, and UKR 44188 was confirmed to be an isolate of PPV strain D. UKR 44189 and UKR 44191 are very closely related to the PPV strain W isolate LV-145bt (HQ670748) from Latvia. Nucleotide and amino acid sequence identities between these three isolates were greater than 99%. This indicates that the isolates are very closely related and likely originated from a common source. The high genetic diversity among PPV-W strain isolates allowed the identification of potential recombination events between PPV isolates. It appears also that GF 305 peach and Prunus tomentosa are not hosts for the PPV isolate UKR 44189.

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

H., Lee, F. N., and Correll, J. C. 2013. Confirming QTLs and finding additional loci responsible for resistance to rice sheath blight disease. Plant Dis. 97:113-117. Rice sheath blight disease, caused by Rhizoctonia solani AG1-1A, is one of the most destructive rice diseases worldwide. Utilization of host resistance is the most economical and environmentally sound strategy in managing sheath blight (ShB). Ten ShB quantitative trait loci (QTLs) were previously mapped in a Lemont x Jasmine 85 recombinant inbred line (LJRIL) population using greenhouse inoculation methods at an early vegetative stage. However, confirmation of ShB-resistant QTLs under field conditions is critical for their utilization in marker-assisted selection (MAS) for improving ShB resistance in new cultivars. In the present study, we evaluated ShB resistance using 216 LIRILs under field conditions in Arkansas. Texas, and Louisiana during 2008 and 2009. We confirmed the presence of the major ShB-QTL qShB9-2 based on the field data and also identified one new ShB-QTL between markers RM221 and RM112 on chromosome 2 across all three locations. Based on the field verification of ShB evaluations, the microchamber and mist-chamber assays were simple, effective, and reliable methods to identify major ShB-QTLs like qShB9-2 in the greenhouse at early vegetative stages. The markers RM215 and RM245 were found to be closely linked to aShB9-2 in greenhouse and field assays, indicating that they will be useful for improving ShB resistance in rice breeding programs using MAS.

Expression of bacterial blight resistance in Brassica leafy greens under field conditions and inheritance of resistance in a Brassica juncea source. Plant Dis. 97:131-137. Brassica leafy greens are one of the most economically important vegetable commodity groups grown in the southeastern United States, and more than 28,000 metric tons of these crops are harvested in the United States annually. Collard and kale (Brassica oleracea Acephala group), mustard green (B. juncea), and turnip green (B. rapa) are the most commonly planted members of the brassica leafy greens group. In the last 10 years, numerous occurrences of bacterial blight on these leafy vegetables have been reported in several states. One of the pathogens responsible for this blight is designated Pseudomonas cannabina pv. alisalensis. Two B. rapa (G30710 and 030499) and two B. juncea (PI418956 and G30988) plant introductions (PIs) that exhibited moderate to high levels of resistance to this pathogen in greenhouse studies were tested for field resistance in comparison with eight commercial cultivar representatives of turnip green, mustard green, collard, and kale. The two B. juncea Pis and one of the B. rapa PIs (G30499) were found to have significantly less disease than all tested cultivars except 'Southern Curled Giant mustard green (B. juncea) and 'Blue Knight' kale (B. oleracea). Inheritance of resistance studies performed with populations derived from the resistant G30988 and two susceptible Pis provided some evidence that resistance may be controlled by a single recessive gene.

The effectiveness of SIT programs depends on sterile males mating successfully and inducing reproductive failure in wild females, or in the F1 generation in the case of lepidopteran species. Thus, from the perspective of insect control, female mating failure involves mating with a mass-reared, sterilized male, which then results in female reproductive failure. Here, we review female mating failure in the context of SIT at two stages. First, at the pre-copulatory stage we consider factors that affect female mating failure with sterile males, such as differences between sterile and wild males in terms of male courtship success, male discrimination of females, pheromone production, and dispersal. We emphasize studies with some degree of ecological realism and review certain factors that can affect female sexual development and choice, such as diet, age, and sex ratio. Second, at the post-copulatory stage we consider factors that functionally result in female reproductive failure, such as ejaculate transfer and control of female remating. Sterile insect technique operations strive to incorporate methods that increase wild female mating with sterile males so that ultimately population-wide reproductive failure is achieved in the target species.

Populations comprised of fewer individuals tend to be subject to stochastic forces and Allee effects (positive-density dependence), which can challenge the ability of small founder populations to establish in a new area. Although the conceptual relationship between initial colony size and establishment success has been previously documented, it is not trivial to estimate precisely the colony size needed to ensure colony persistence. Over the last 40 years, there have been many studies on the probability of mating success of female Lymantria dispar (L.) (Lepidoptera: Lymantriidae) in the USA related to background male moth densities. We were motivated by this wealth of data and sought to combine the results from these prior studies with the goal of estimating a robust measure of the male moth density required to achieve varying levels of female mating success. Although the data are specific to L. dispar, the pheromone communication system in L. dispar is not unique and thus the results of this analysis could be broadly applicable to our general understanding of Lepidoptera mating behavior.

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

The mechanism(s) by which this occurs has not been clearly elucidated. To explore possible mechanisms, X. fastidiosa cells from a PD strain were grown in pure xylem fluid of PD-susceptible grapevines, Vitis vinifera and V. labrusca, versus PD-resistant grapevines, V. champinii and V. smalliana. When grown in xylem fluid from the susceptible species, X. fastidiosa cells formed a heavier biofilm compared to those in xylem fluid from the resistant species. Differential expression of selected genes of X. fastidiosa cultured in the xylem fluids of V. vinifera and V. smalliana was analyzed using a DNA macroarray. Compared with xylem fluid of V. smalliana, xylem fluid of V. vinifera stimulated the expression of X. fastidiosa genes involved in virulence regulation, such as rpfC, gacA, xrvA, gcvR, and cysB, and genes involved in biogenesis of pili and twitching motility, such as pilI, pilU, pilE and pilG. Increased expression of virulence genes likely contributes to the expression of PD symptom in the susceptible grapevines, whereas reduced expression of these genes may lead to limitation of symptoms in resistant grapevines.

We studied this relationship across 69.2 km(2) of Yosemite National Park, USA, that was subject to 32 fires >= 40 ha between 1984 and 2010. Forests types included ponderosa pine (Pious ponderosa), white fir-sugar pine (Abies concolor/Pinus lambertiana), and red fir (Abies magnifica). We estimated and stratified burned area by fire severity using the Landsat-derived Relativized differenced Normalized Burn Ratio (RdNBR). Airborne LiDAR data, acquired in July 2010, measured the vertical and horizontal structure of canopy material and landscape patterning of canopy patches and gaps. Increasing fire severity changed structure at the scale of fire severity patches, the arrangement of canopy patches and gaps within fire severity patches, and vertically within tree clumps. Each forest type showed an individual trajectory of structural change with increasing fire severity. As a result, the relationship between estimates of fire severity such as RdNBR and actual changes appears to vary among forest types. We found three arrangements of canopy patches and gaps associated with different fire severities: canopy-gap arrangements in which gaps were enclosed in otherwise continuous canopy (typically unburned and low fire severities); patch-gap arrangements in which tree clumps and gaps alternated and neither dominated (typically moderate fire severity); and open-patch arrangements in which trees were scattered across open areas (typically high fire severity). Compared to stands outside fire perimeters, increasing fire severity generally resulted first in loss of canopy cover in lower height strata and increased number and size of gaps, then in loss of canopy cover in higher height strata, and eventually the transition to open areas with few or no trees. However, the estimated fire severities at which these transitions occurred differed for each forest type. Our work suggests that low severity fire in red fir forests and moderate severity fire in ponderosa pine and white fir-sugar pine forests would restore vertical and horizontal canopy structures believed to have been common prior to the start of widespread fire suppression in the early 1900s. The fusion of LiDAR and Landsat data identified post-fire structural conditions that would not be identified by Landsat alone, suggesting a broad applicability of combining Landsat and LiDAR data for landscape-scale structural analysis for fire management.

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

Despite this trend, there have been few studies investigating post-fire tree regeneration. We established a study in the footprint of the 2000 Storrie Fire, a 23,000 ha wildfire that occurred in northern California, USA. We used a stratified sampling design to quantify post-fire vegetation dynamics across four levels of burn severity and three forest types on the Lassen National Forest nine and ten years following fire. Within each sampled stand, we recorded tree seedlings, forest overstory, shrub cover, and abiotic factors hypothesized to influence growth and establishment. Median conifer seedling densities varied substantially by burn severity: 1918 seedlings ha(-1) in the Unchanged units; 4838 seedlings ha(-1) in the Low-severity units; 6484 seedlings ha(-1) in the Medium-severity units; and 710 seedlings ha(-1) in the High-severity units. Increased burn severity was associated with greater shrub coverage: shrub cover in High-severity burns was more than three times those of lower burn severities. We calculated Shannon's Species Diversity (H') and Pielou's Evenness (E-H) indices to examine woody shrub and tree diversity. Abies spp. were by far the most abundant regenerating conifer species, which may be a concern for land managers; shrub cover after High-severity burns was dominated by Ceanothus spp. Although fir regeneration was prolific, the Storrie Fire generated diverse vegetative responses, potentially aiding in the reintroduction of the diverse landscape mosaic homogenized by a century of landscape-scale fire exclusion.

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

Fertilization treatments were randomly applied to 0.01 ha plots centered on individual dominant or co-dominant Douglas-fir trees in ten Douglas-fir stands from coastal Oregon to the foothills of the Oregon Cascade Range, USA. This region is affected by Swiss needle cast, caused by the fungal pathogen Phaeocryptopus gaeumannii. Selected stands represented a range of Swiss needle cast disease severity, and 10 replications of each fertilization treatment were applied in each stand. The six treatments included nitrogen (urea), calcium as lime (calcium carbonate), calcium as calcium chloride, phosphorus (monosodium phosphate), a site-specific blend (Kinsey) and an unfertilized control. Fertilization took place from February-April 2007, and single branches were collected from treated trees for disease severity assessment of foliage in May 2010. Disease severity of 1- and 2-year-old needles was evaluated by counting the frequency of infected needles and the density of P. gaeumannii fruiting bodies (pseudothecia) on a random subset of needles from each tree and needle age class. Fertilization treatment effects on infection index (mean fruiting body density) were tested by mixed-effects models that accounted for site as a blocking factor. Treatment effects on infection index at each of the study locations were also tested by ten separate ANO-VAs. Across and within sites, fertilization treatment did not significantly affect infection index of 1- or 2-year old needles (p > 0.05). Small differences in mean fruiting body density (<= 3%) between fertilization and control treatments across sites were not statistically significant, nor are they believed to be biologically or economically significant. Decisions regarding fertilization should be based on site-specific attributes, such as soil chemistry. There is no evidence that fertilization directly ameliorates or exacerbates Swiss needle cast severity in western Oregon. Published by Elsevier B.V.

The impact of NT/RT on N2O emissions, however, has been variable with both increases and decreases in emissions reported. Herein, we quantitatively synthesize studies on the short- and long-term impact of NT/RT on N2O emissions in humid and dry climatic zones with emissions expressed on both an area- and crop yield-scaled basis. A meta-analysis was conducted on 239 direct comparisons between conventional tillage (CT) and NT/RT. In contrast to earlier studies, averaged across all comparisons, NT/RT did not alter N2O emissions compared with CT. However, NT/RT significantly reduced N2O emissions in experiments >10 years, especially in dry climates. No significant correlation was found between soil texture and the effect of NT/RT on N2O emissions. When fertilizer-N was placed at =5 cm depth, NT/RT significantly reduced area-scaled N2O emissions, in particular under humid climatic conditions. Compared to CT under dry climatic conditions, yield-scaled N2O increased significantly (57%) when NT/RT was implemented <10 years, but decreased significantly (27%) after =10 years of NT/RT. There was a significant decrease in yield-scaled N2O emissions in humid climates when fertilizer-N was placed at =5 cm depth. Therefore, in humid climates, deep placement of fertilizer-N is recommended when implementing NT/RT. In addition, NT/RT practices need to be sustained for a prolonged time, particularly in dry climates, to become an effective mitigation strategy for reducing N2O emissions.

A concern for species conservation is whether or not the rate of on-going climate change will exceed the rate at which species can adapt or move to suitable environments. Here we assess the climate velocity (both climate displacement rate and direction) for minimum temperature, actual evapotranspiration, and climatic water deficit (deficit) over the contiguous US during the 20th century (19162005). Vectors for these variables demonstrate a complex mosaic of patterns that vary spatially and temporally and are dependent on the spatial resolution of input climate data. Velocities for variables that characterize the climatic water balance were similar in magnitude to that derived from temperature, but frequently differed in direction resulting in the divergence of climate vectors through time. Our results strain expectations of poleward and upslope migration over the past century due to warming. Instead, they suggest that a more full understanding of changes in multiple climatic factors, in addition to temperature, may help explain unexpected or conflicting observational evidence of climate-driven species range shifts during the 20th century.

However, the ability of PAS to measure N2O with accuracy and precision similar to gas chromatography (GC) is uncertain due to overlap in N2O, CO2, and H2O absorbance spectra combined with the large range in analyte concentrations. We tested the ability of six PAS units to simultaneously measure N2O and CO2 gas concentrations and fluxes with accuracy and precision similar to two GC units. We also evaluated H2O vapor and CO2 interferences with N2O measurement. The accuracy and precision of standard gas concentration measurements with PAS and GC were similar. High water vapor (similar to 26 600 ppm) and CO2 concentrations (similar to 4500 ppm) did not interfere with N2O measurement across the concentration range typically observed in static flux chambers at the soil surface (similar to 0.53.0 ppm N2O). On average, N2O fluxes measured with the six PAS were 4.7% higher than one GC and 9.9% lower than the second GC.

However, little is known about the evolution of the species that gave rise to this important fruit crop. phylogenetic analysis of chloroplast genome sequences of 21 Fragaria species and subspecies resolves the western North American diploid F. vesca subsp. bracteata as sister to the clade of octoploid/decaploid species. No extant tetraploids or hexaploids are directly involved in the maternal ancestry of the octoploids. There is strong geographic segregation of chloroplast haplotypes in subsp. bracteata, and the gynodioecious Pacific Coast populations are implicated as both the maternal lineage and the source of male-sterility in the octoploid strawberries. Analysis of sexual system evolution in Fragaria provides evidence that the loss of male and female function can follow polyploidization, but does not seem to be associated with loss of self-incompatibility following genome doubling. Character-state mapping provided insight into sexual system evolution and its association with loss of self-incompatibility and genome doubling/merger. Fragaria attained its circumboreal and amphitropical distribution within the past one to four million years and the rise of the octoploid clade is dated at 0.372-2.05 million years ago.

These proteins act as ligand mimics of plant CLE peptides and are required for successful nematode infection. Previously, we showed that the CLV2/CORYNE (CRN) heterodimer receptor complex is required for nematode CLE signaling. However, there was only a partial reduction in nematode infection when this signaling was disrupted, indicating that there might be additional nematode CLE receptors. In this study, we demonstrate that CLV1 and RECEPTOR-LIKE PROTEIN KINASE 2/TOADSTOOL2 (RPK2), two additional receptors that can transmit the CLV3 signal independent of CLV2/CRN for shoot apical meristem maintenance, also play a role in nematode CLE perception. Localization studies showed that both receptors are expressed in nematode-induced syncytia. Infection assays with clv1 and rpk2 single mutants revealed a decrease in both nematode infection and syncytium size. Significantly, further reduction in nematode infection was observed when rpk2 was combined with clv1 and clv2 mutants. Taken together, our results indicate that parallel signaling pathways involving CLV1, CLV2, and RPK2 are important for nematode parasitism.

SO NATURE REVIEWS ENDOCRINOLOGY LA English DT Review ID GAMMA-CARBOXYGLUTAMIC ACID; BONE-MINERAL DENSITY; VITAMIN-K SUPPLEMENTATION; TYPE-2 DIABETES-MELLITUS; BETA-CELL FUNCTION; SERUM OSTEOCALCIN; ENERGY-METABOLISM; BIOCHEMICAL MARKERS; GLA-PROTEIN; UNDERCARBOXYLATED OSTEOCALCIN AB Increasing evidence supports an association between the skeleton and energy metabolism. These interactions are mediated by a variety of hormones, cytokines and nutrients. Here, the evidence for a role of osteocalcin in the regulation of glucose metabolism in humans is reviewed. Osteocalcin is a bone matrix protein that regulates hydroxyapatite size and shape through its vitamin-K-dependent, gamma-carboxylated form. The concentration of osteocalcin in the circulation is a measure of bone formation. The undercarboxylated form of osteocalcin is active in glucose metabolism in mice. Total serum osteocalcin concentrations in humans are inversely associated with measures of glucose metabolism; however, human data are inconclusive with regard to the role of uncarboxylated osteocalcin in glucose metabolism because most studies do not account for the influence of vitamin K on the proportion of undercarboxylated osteocalcin or differentiate between the total and uncarboxylated forms of osteocalcin. Furthermore, most human studies do not concomitantly measure other bone turnover markers to isolate the role of osteocalcin as a measure of bone formation from its effect on glucose metabolism. Carefully designed studies are required to define the role of osteocalcin and its carboxylated or undercarboxylated forms in the regulation of glucose metabolism in humans. Booth, S. L. et al. Nat.

Disease control is mainly achieved by timely fungicide applications. In 2011, CLS control failures were reported in spite of application of quinone outside inhibitor (QoI) fungicide in several counties in Michigan, United States. The purpose of this study was to confirm the resistant phenotype and identify the molecular basis for QoI resistance of Michigan C. beticola isolates. RESULTS: Isolates collected in Michigan in 1998 and 1999 that had no previous exposure to the QoI fungicides trifloxystrobin or pyraclostrobin exhibited QoI EC50 values of <= 0.006 mu g mL-1. In contrast, all isolates obtained in 2011 exhibited EC50 values of > 0.92 mu g mL-1 to both fungicides and harbored a mutation in cytochrome b (cytb) that led to an amino acid exchange from glycine to alanine at position 143 (G143A) compared with baseline QoI-sensitive isolates. Microsatellite analysis of the isolates suggested that QoI resistance emerged independently in multiple genotypic backgrounds at multiple locations. A real-time PCR assay utilizing dual-labeled fluorogenic probes was developed to detect and differentiate QoI-resistant isolates harboring the G143A mutation from sensitive isolates. CONCLUSION: The G143A mutation in cytb is associated with QoI resistance in C. beticola. Accurate monitoring of this mutation will be essential for fungicide resistance management in this pathosystem.

LEPIDOPTERA; LARVAE; OLETHREUTIDAE; GRANULOVIRUS; MANAGEMENT; KAIROMONE; CODLEMONE AB BACKGROUND: The possibility of improving the efficacy of various insecticides for codling moth, Cydia pomonella (L.), by the addition of a microencapsulated formulation of pear ester, ethyl (2E, 4Z)-2,4-decadienoate (PE-MEC, 5% AI), was evaluated in field trials in apple from 2005 to 2009. RESULTS: The addition of PE-MEC (<3.0 g AI ha-1) significantly lowered fruit injury with low rates of organophosphate and neonicotinoid insecticides. The addition of PE-MEC (1.48 g AI ha-1) to maximum label rates of insecticides with moderate activity for codling moth, such as ebamectin benzoate, spinosad and methoxyfenozide, significantly improved their effectiveness. However, PE-MEC did not consistently improve the activity of maximum label rates of either rynaxypyr or spinetoram. The addition of PE-MEC with seasonal spray programs of acetamiprid and azinphos-methyl in combination with the use of sex pheromones for mating disruption provided the most effective control. CONCLUSION: The addition of PE-MEC can improve the effectiveness of some insecticides for codling moth in apple. Insecticides active via dermal toxicity are more strongly improved by the addition of PE-MEC. Season-long use of PE-MEC can also augment the effectiveness of mating disruption. Adding PE-MEC to variable integrated management programs for C. pomonella should be further investigated. Published 2012 by John Wiley & Sons, Ltd.

RESULTS: There was little dissipation of chlorfenapyr in soil treated at the labeled rate for perimeter treatments for the prevention and control of termite infestations. Chlorfenapyr was detected in soil immediately below the initially treated soil in the packed soil columns. This was likely due to settling of soil. The treated soil remained toxic to subterranean termites in 3 and 7 day bioassays over the duration of the study. The treated soil displayed slow-acting properties regarding toxicity to termites. Trace amounts of chlorfenapyr were detected in the eluates of packed soil cones. CONCLUSION: The commercial formulation of chlorfenapyr used in this study (21.45% concentrate diluted to 0.125% prior to application) killed 100% of the tested subterranean termites for at least 30 months.

TI Trade-adjusted measures of productivity increases in US hog production SO AGRICULTURAL SYSTEMS LA English DT Article DE Hogs; Pork; Productivity; Genetics; Imports ID RESEARCH-AND-DEVELOPMENT; CARCASS TRAITS; FACTOR DEMAND; AGRICULTURE; DUALITY; CATTLE AB The average dressed weight for barrows and gilts slaughtered in the United States has increased 23% since 1977, from an annual average of 163 lbs to 201 lbs in 2010. This measure of pork production includes pork produced from US born and raised hogs as well as hogs imported from Canada. This paper addresses technological change in US born and raised pork production. Since pork produced from Canadian hogs could distort estimates of technological improvement and other variables describing changes in US born and raised pork production, a method of adjusting production data series for the portion of US pork production that comes from foreign-born hogs is developed. The resulting data are used to estimate the rate of change in average dressed weight, assumed to be due to technical change in the US swine herd. Published by Elsevier Ltd.

Input sources included four years, spanning 2008-2011, of annual national-level coverage Cropland Data Layer (CDL) land cover classifications as produced by the National Agricultural Statistics Service. Derived total land area under tillage from the aggregate CDL product equaled 112.8 million hectares (278.7 million acres). By comparison, the 2007 Census of Agriculture (CoA) produced an estimate of 122.9 million hectares, suggesting the map is under representing tilled area by 10.1 million hectares or 8.2%. Regression analysis using state-level summaries showed a strong, albeit biased, correlation (r-squared = 0.99) between the CDL derived tilled area and the CoA information. Notable outliers were North Dakota and Montana. Comparisons of the CDL tilled map were also made against the 2006 National Land Cover Dataset (NLCD) land cover product's Cultivated Crops category. Strong state-level regression agreement (r-squared = 0.98) was also found between the NLCD and the CDL acreages, but the NLCD estimated 8.5% more area than the CDL and thus closely matched that of the CoA. However, significant pixel level differences were found between the CDL and the NLCD. Nationally 5.6% of the maps were in disagreement as to whether cultivated or not, a large proportion considering around a seventh of the country's land area is tilled. States of Arkansas, Montana and Wisconsin had the largest absolute discrepancies between the NLCD and CDL. Accepting the CDL as reference showed a national level NLCD cropland commission error of 23.0% and omission error of 14.5%. Much of what is believed to be problematic in the NLCD could be explained by definitional issues having included alfalfa hay into their cultivated category for many areas. Ultimately, while it is likely that the CDL annually tilled area model is an underestimate of the true total, taken contextually in map form and adjusted for undercount bias it likely is the best available.

A 26 ha rodent snap-trap grid was installed in montane forest on Oahu Island, Hawaii, in order to protect endangered snails and plants. To assess the effectiveness of this trapping operation in reducing fruit consumption and seed predation of the endangered Hawaiian lobeliad, Cyanea superba subsp. superba, pre- and post-dispersal C. superba fruit consumption were monitored for 36 plants at the site with rodent control (Kahanahaiki) and 42 plants at an adjacent site without rodent control (Pahole). Over 47 % of all monitored fruit were eaten on the plants at Pahole compared to 4 % at Kahanahaiki. Images captured using motion-sensing cameras suggest that black rats (Rattus rattus) were the only pre-dispersal fruit consumers. To quantify post-dispersal fruit consumption, and to identify the culprit frugivore(s), mature fruit were placed in tracking tunnels positioned on the forest floor and checked daily. At Pahole, all of the fruit were consumed by rats compared to 29 % at Kahanahaiki. Lastly, to determine if rodents from the sites were predators or dispersers of C. superba seed, fruit were fed to captive black rats and house mice (Mus musculus). Black rats consumed entire fruit, killing all the seed, while mice did little damage to the fruit and seed. Therefore, large-scale rat trapping can directly benefit the reproduction of C. superba subsp. superba. Controlling black rats at restoration sites appears integral to the successful restoration of this endangered plant species.

Strains NRRL Y-2311-1, NRRL 50382, NRRL 50383, and NRRL 50384, representing diverse isolation sources and phylogenetic clades, produced PMA from alkaline H2O2-pretreated corn fiber and wheat straw as sole carbon sources. Pretreated wheat straw was better than pretreated corn fiber, and strain NRRL 50383 gave the highest overall yields of PMA. The addition of CaCO3 plus supplementary hydrolytic enzymes enhanced PMA production. Four basal media were compared for PMA production, and the best was found to be a N-limited pullulan production medium (PM). In this medium, PMA production took place during growth limitation. Under optimal conditions, strain NRRL 50383 produced more than 20 g PMA/l from 5 % (w/v) pretreated wheat straw in PM with 3 % (w/v) CaCO3 and supplementary enzymes.

Arcang.] accessions of the Adriatic coast were screened genetically and for their adaptive morpho-functional root traits in order to identify new sources of abiotic resistances for sugar beet breeding programs. Genetic diversity was evaluated with 21 microsatellites markers that identified 44 polymorphic alleles. Sea beets grouped into two main clusters: the West and the East Adriatic coast groups, with the latter showing higher genetic diversity. Among sea beet accessions with desirable root traits, four accessions have proved to be interesting for sugar beet [B. vulgaris (L.) ssp. vulgaris] breeding aimed to improve tolerance to nutritional stresses. Lastovo (ID 29) and Zut (ID 34) accessions were characterized by the highest values of RER, TRL, FRL and RSA still maintaining a high value of RTD, while Grado (ID 21) an Portic (ID 23) accessions were characterized by the highest RTD, but with low values of RER, TRL, FRL and RSA parameters.

Biodiesel has been proven to be a suitable alternative to petrodiesel and blending up to 20% biodiesel with petrodiesel is policy promoted in the USA and the EU. To investigate the influence of blends on the exhaust emissions and possible health effects, we performed a series of studies with several engines (Euro 0, III and IV) using blends of rapeseed-derived biodiesel and petrodiesel. Regulated and non-regulated exhaust compounds were measured and their mutagenic effects were determined using the Bacterial Reverse Mutation Assay (Ames-Test) according to OECD Guideline 471. Exhaust emissions of blends were approximately linearly dependent on the blend composition, particularly when considering regulated emissions. However, a negative effect of blends was observed with respect to mutagenicity of the exhaust emissions. In detail, an increase of the mutagenic potential was found for blends with the maximum observed for B20. From this point of view, B20 must be considered as a critical blend when petrodiesel and biodiesel are used as binary mixtures. (C) 2012 Elsevier Ltd. All rights reserved.

Common occurrence of limestone fragments in their household middens suggests 1) limestone may have been used as the heating element for stone-boiling maize and 2) this practice might have made some maize proteins more available for human nutrition. Experiments examined these possibilities; results indicate that stone-boiling with Cedar Mesa limestone creates an alkaline cooking environment suitable for nixtamalization of maize kernels, and that maize cooked in this fashion shows significant increases in availability of lysine, tryptophan, and methionine. Archaeological limestone fragments from a Grand Gulch phase site show amounts of fragmentation and changes in density consistent with repeated heating. While not conclusive, these data indicate that further research (e.g., examination of archaeological limestone fragments for maize starch grains or phytoliths) is warranted. It is suggested that greater attention be paid to archaeological indications of stone-boiling with limestone among maize-dependent but pre-pottery societies. (C) 2012 Elsevier Ltd.

However, such shifts in appropriate response to a hazard, whether at the individual or at the societal level, are rarely straightforward: Closing the gap between desired practice and current practice requires effective communication. Although there is a significant literature on how to encourage adaptation before an event and how to communicate during an event, there is less work tying the two together or on how to communicate shifts in larger scale societal response to a natural hazard. In this article, we bring together the best practices and theoretical literature from risk communication and crisis communication and empirical literature on wildfire communication to derive the key characteristics associated with best communication practices. We then use this framework on three case studies of wildfires in California, Montana, and Wyoming, each of which used a different strategy for managing the fire, to understand whether approaching communication more holistically can lead to more desired natural hazard management outcomes. Our working hypothesis was as follows: effective communication before and during a fire would be associated with acceptance of more flexible fire management strategies. The findings indicate how a type of desired management change (more flexible fire management) is associated with more effective communication practices before and during the event.

The aim of this study was to understand the hydraulic determinants of midday gs, the coordination between leaf and stem hydraulics and whether regulation of midday gs differed between deciduous and evergreen broadleaf tree species in a subtropical cloud forest of Southwest (SW) China. We investigated leaf and stem hydraulics, midday leaf and stem water potentials, as well as midday gs of co-occurring deciduous and evergreen tree species. Midday gs was correlated positively with midday stem water potential across both groups of species, but not with midday leaf water potential. Species with higher stem hydraulic conductivity and greater daily reliance on stem hydraulic capacitance were able to maintain higher stem water potential and higher gs at midday. Deciduous species exhibited significantly higher stem hydraulic conductivity, greater reliance on stem capacitance, higher stem water potential and gs at midday than evergreen species. Our results suggest that midday gs is more associated with midday stem than with leaf water status, and that the functional significance of stomatal regulation in these broadleaf tree species is probably for preventing stem xylem dysfunction.

Results of this self-evaluation is expected to be used to improve educational programs. As part of the effort to improve educational programs based on a self evaluation of an active learning model, this study investigates how creativity can be fostered among freshman engineering students as a result of exposing them to various creative problem solving exercises in an active, experiential, and team-based learning environment. An introductory course to engineering design at Texas A&M University was used to determine how creativity was promoted among students after completing the course. Established research findings in creativity studies were used to measure creativity both as a construct and a process among students. Qualitative approaches were used and the research design included extensive field observations, focus group interviews, student questionnaires, and portfolios assessments. Results of the study showed that the use of an experiential and team-based learning model in the freshman engineering design course enhanced both process-and construct-based creativity dimensions among students during the course of the study.

ECGlib has a modular design, and is capable of handling files stored in many different formats, e.g. ISHNE, Physionet and FDA HL7. Moreover, ECGlib provides functions to do standard ECG signal processing, such as noise removal, QRS detection, classification, median beat creation and ECG waveform delineation. The performance of the different components of ECGlib has been evaluated using publicly available databases from Physionet (MIT-BIH and QTDB). The performance of ECGlib processing methodologies is comparable to state-of-the-art methods. We have also developed a MATLAB/Octave interface for ECGlib and are working on an interface for Python, R and Julia. Lastly, ECGlib comes with a set of command line tools that utilize parallel processing to quickly enable researchers to process large databases. We believe frameworks such as the one described can be used to facilitate research of ECG signals and we are working on making the library publicly available under an open source license.

The purpose of using remote sensed SMAP data for crop soil moisture monitoring is to eliminate data collection subjectivity, reduce cost, increase cropland soil moisture monitoring data consistency, and operational efficiency. In this paper, the SMAP simulated data product time series, such as L2_SM_A, L3_SM_A/P, L4_SM, LIC-S0_HiRes are first evaluated for their suitability for NASS operational cropland soil moisture monitoring by comparing SMAP results with the NASS' survey based weekly soil moisture observation data for their consistency and robustness. The preliminary results illustrate that SMAP products have the potential for NASS operational use at least for county level soil moisture statistics. This paper also explores a technical route to build a Web-service based interactive soil moisture monitoring system for map visualization, dissemination, and analysis based on SMAP results.

Blow-up fire behaviour is difficult to predict and has been linked to firefighter fatalities, making it an important fire management hazard. Byram (1954) compiled the first observational dataset of categorised wind speed and direction profiles associated with blow-up fire behaviour. Low-level jets, varying in height between 30 and 1000 m above ground level (AGL), are a common feature in Byram's wind-profile types. Additional studies have qualitatively discussed how low-level jets can influence wildland fire behaviour and pyro-convective plume dynamics. However, there has been little quantitative testing and analysis of the physical processes linking low-level jets and blow-up fire behaviour. The principle aim of this study was to use the Advanced Regional Prediction System (ARPS) at high-resolution, with a 50 m horizontal grid spacing, to numerically simulate the sensitivity of the downwind pyro-convective plume dynamics to four of the Byram wind-profile types. The Byram wind profiles tested each contain a low-level jet with different properties. A moderate-intensity grass fire was prescribed in the ARPS model domain using a constant surface sensible heat flux of 30 kW m(-2) in a 150 x 2500 m rectangle oriented normal to the prevailing wind. The numerical simulation results indicated that the fire-related atmospheric conditions and large-scale pyro-convective plume structure were sensitive to changes in the low-level jet properties, i.e. wind shear above the jet and the jet height and intensity. However, despite this sensitivity there were some common features in the four numerical simulations. A triangular-shaped fire-perturbed warm air region developed close to the surface downwind of, and extending from, the steady-state parameterized fire. This warm air region was confined spatially by cross-wind inflows that developed due to an interaction of the background winds with the edges of the fire. The horizontal convergence of these cross-wind inflows downwind of the fire marked the starting location of the fire plume. There were considerable updrafts and downdrafts throughout the model domain associated with the pyro-convection. The heating of air up to several kilometres downwind of the fire would act to preheat fuels, resulting in increased fuel flammability and therefore an enhanced rate of forward fire spread. Additionally, the atmospheric turbulence directly over this warm air region and the updrafts and downdrafts associated with the fire plume would affect the transportation of firebrands downwind of the fire. The downwind transportation of firebrands can ignite spot fires, which enhance the forward rate of fire spread as the spot fires grow and merge with the existing fire front. Through these mechanisms the low-level jet wind profiles can be directly linked with blow-up fire behaviour. The numerical simulations performed with ARPS were highly idealised and therefore subject to a number of limitations. For example, temporal variations in the prescribed fire intensity and shape, directional wind shear, background turbulence and moist processes were not modelled in this study. However, future work will gradually address these limitations through further numerical simulations using both ARPS and a coupled atmosphere-fire model.

In practice, both model and observation uncertainties are difficult to quantify thus have been often assumed to be spatially and temporally independent Gaussian random variables. Nevertheless, it has been shown that incorrect assumptions regarding the structure of these errors can degrade the performance of the stochastic data assimilation. This work investigates the autocorrelation structure of the microwave satellite soil moisture retrievals and explores how assumed observation error structure affects streamflow prediction skill when assimilating these observations into a rainfall-runoff model. An AMSR-E soil moisture product and the Probability Distribution Model (PDM) are used for this purpose. Satellite soil moisture data is transformed with an exponential filter to make it comparable to the root zone soil moisture state of the model. The exponential filter formulation explicitly incorporates an autocorrelation component in the rescaled observation, however, the error structure of this operator has been treated until now as an independent Gaussian process. In this work, the variance of the rescaled observation error is estimated based on the residuals from the rescaled satellite soil moisture and the calibrated model soil moisture state. Next, the observation error structure is treated as a Gaussian independent process with time-variant variance; a weakly autocorrelated random process (with autocorrelation coefficient of 0.2) and a strongly autocorrelated random process (with autocorrelation coefficient of 0.8). These experiments are compared with a control case which corresponds to the commonly used assumption of Gaussian independent observation error with time-fixed variance. Model error is represented by perturbing rainfall forcing data and soil moisture state. These perturbations are assumed to represent all forcing and model structural/parameter errors. Error parameters are calibrated by applying two discharge ensemble verification criteria. Assimilation results are compared and the impacts of the observation error structure assumptions are assessed. The study area is the semi-arid 42,870 km(2) Warrego at Wyandra River catchment, located in Queensland, Australia. This catchment is chosen for its flooding history, along with having geographical and climatological conditions that enable soil moisture satellite retrievals to have higher accuracy than in other areas. These conditions include large area, semi-arid climate and low vegetation cover. Moreover, the catchment is poorly instrumented, thus satellite data provides valuable information. Results show a consistent improvement of the model forecast accuracy of the control case and in all experiments. However, given that a stochastic assimilation is designed to correct stochastic errors, the systematic errors in model prediction (probably due to the inaccurate forcing data within the catchment) are not addressed by these experiments. The assumed observation error structures tested in the different experiments do not exhibit significant effect in the assimilation results. This case study provides useful insight into the assimilation of satellite soil moisture retrievals in poorly instrumented semi-arid catchments. C1 [Alvarez-Garreton, C.; Ryu, D.; Western, A.

Accurate and current observations of soil moisture over meso to global scales used as inputs to hydrological, weather and climate modelling will benefit the predictability and understanding of these processes. At present, satellite platforms are active in mapping global surface soil moisture jointly at sub-daily intervals and mesoscale resolutions. However to correctly interpret observed variations and assimilate them in hydrological and weather models, the error structures of the retrieved soil moisture data need to be better understood and characterised. In this paper we investigate the utility of a recently proposed method to quantify the variance of stochastic noise in passive and active satellite soil moisture products. While it is typical to analyse the difference between satellite retrievals and ground truth in the time domain, this method is based on quantifying the differences between retrieved soil moisture and a standard water-balance equation in the conjugate Fourier domain. The method, which referred to as Spectral Fitting (SF), is applied to estimate the errors in passive and active retrievals over Australia (10-44 degrees South, 112-154 degrees East). In particular we consider the AMSR-E (Advanced Microwave Scanning Radiometer - Earth Observing System) LPRM (Land Parameter Retrieval Method), CATDS (Centre Aval de Traitement des Donnees SMOS) SMOS (Soil Salinity and Ocean Salinity), and TU-WIEN (Vienna University of Technology) ASCAT (Advanced Scatterometer) soil moisture products. The results are compared against the errors estimated using the standard method of triple collocation (TC) with AMSR-E, SMOS and ASCAT as the data triplet. Our analyses show that the SF method is able to recover similar and reasonable error maps that reflect sensitivity of retrieval errors to land surface and climate characteristics over Australia. As expected, more vegetated and wetter areas are usually associated with higher errors. Additionally for SMOS and ASCAT, the dry cooler desert areas of southern Australia also show higher errors, in contrast to lower errors over the hotter dry desert of central Australia. The reverse is the case for AMSR-E. These patterns are also reflected in the spatial error maps of TC analysis and the direct comparisons of SF and TC estimates show moderate-to-good correlations: 0.64 for AMSR-E, 0.68 for SMOS, and 0.68 for ASCAT. However the SF yields lower estimates than TC at the high end of the range. On one hand, this is perhaps expected given rationale of the SF method to estimate only the stochastic/high-frequency components of the total errors. On the other hand, the simple error model and implementation of TC with non-coincident overpass times can also over-estimate the errors. This work therefore presents an additional perspective on satellite soil moisture observation errors (in the Fourier domain) that may complement other error estimation approaches (in the time domain), thereby improving our understanding of the sources and types of errors.

This study concludes that a structural break in the U.S. cotton industry occurred in 1999, and that world cotton supply has become an important determinant of U.S. cotton prices. The model developed here forecasts changes in U.S. cotton price based on changes in U.S. cotton supply, changes in U.S. stocks-to-use ratio (S/U), changes in China's net imports as a share of world consumption, the proportion of U.S. cotton engaged in the loan program, and changes in world supply of cotton.

We studied the relatively shade intolerant mahogany (Swietenia macrophylla, Meliaceae) and shade tolerant ramon (Brosimum alicastrum, Moraceae). Both species are ecologically and economically important canopy trees that respond differently to selective logging, hurricanes, and fires on the Yucatan Peninsula. The canopy openness gradient used in the experiment was created by low-intensity selective logging operations. The responses of naturally occurring seedlings of both species growing within 20-30 cm deep circular trenches were examined over a 19-month experimental period. Trenching resulted in increased relative growth in diameter, stem length, and number of leaves of Swietenia compared with controls, but had no effect on Brosimum relative growth or on seedling survival of either species. There was no significant interaction between increased light availability and trenching on Swietenia seedlings, perhaps because of their larger size in gaps. Trenching effects on Swietenia were not greater during the dry season, suggesting that surface trenching affected growth during transitions between seasons. Contrasting responses of Swietenia and Brosimum seedlings to changes in soil and light environments point to the need for diversity in silvicultural practices in seasonally-dry tropical forests such as the community-managed forest examined in this study.

TI A new data set for estimating organic carbon storage to 3m depth in soils of the northern circumpolar permafrost region SO EARTH SYSTEM SCIENCE DATA LA English DT Article ID CLIMATE-CHANGE; SIBERIAN PEATLANDS; ALASKA; CYCLE; VULNERABILITY; SENSITIVITY; BUDGET AB High-latitude terrestrial ecosystems are key components in the global carbon cycle. The Northern Circumpolar Soil Carbon Database (NCSCD) was developed to quantify stocks of soil organic carbon (SOC) in the northern circumpolar permafrost region (a total area of 18.7 x 10(6) km(2)). The NCSCD is a geographical information system (GIS) data set that has been constructed using harmonized regional soil classification maps together with pedon data from the northern permafrost region. Previously, the NCSCD has been used to calculate SOC storage to the reference depths 0-30 cm and 0-100 cm (based on 1778 pedons). It has been shown that soils of the northern circumpolar permafrost region also contain significant quantities of SOC in the 100-300 cm depth range, but there has been no circumpolar compilation of pedon data to quantify this deeper SOC pool and there are no spatially distributed estimates of SOC storage below 100 cm depth in this region. Here we describe the synthesis of an updated pedon data set for SOC storage (kg C m(-2)) in deep soils of the northern circumpolar permafrost regions, with separate data sets for the 100-200 cm (524 pedons) and 200300 cm (356 pedons) depth ranges. These pedons have been grouped into the North American and Eurasian sectors and the mean SOC storage for different soil taxa (subdivided into Gelisols including the sub-orders Histels, Turbels, Orthels, permafrost-free Histosols, and permafrost-free mineral soil orders) has been added to the updated NCSCDv2. The updated version of the data set is freely available on-line in different file formats and spatial resolutions that enable spatially explicit applications in GIS mapping and terrestrial ecosystem models. While this newly compiled data set adds to our knowledge of SOC in the 100-300 cm depth range, it also reveals that large uncertainties remain. Identified data gaps include spatial coverage of deep (> 100 cm) pedons in many regions as well as the spatial extent of areas with thin soils overlying bedrock and the quantity and distribution of massive ground ice. An open access data-portal for the pedon data set and the GIS-data sets is available online at http://bolin.su.se/data/ncscd/. The NCSCDv2 data set has a digital object identifier (doi: 10.5879/ECDS/00000002).

The primary way the soil interacts with the plant is through influences on the root system. The soil serves as an anchor for plant support and as a reservoir for water and plant nutrients. Various factors affect root extension and proliferation and also affect the function of the root in the soil environment. Soil temperature appears to have a greater effect on root development compared with other limiting factors, whereas soil water status, aeration, photosynthate supply, and nutrient availability have a greater effect on root growth. Soil management techniques such as tillage, crop residue cover, irrigation, fertilizer, or machinery traffic all can affect the temperature, water, and aeration status of the soil environment. Zonal differences in the physical condition of the soil can also affect root distribution and the response of the plant to unfavorable conditions. Maintaining the soil in a good condition for plant growth has been and will continue to be an important research topic. This paper addresses several soil physical conditions that affect the development and growth of root systems and proposes ways to include the physical condition of soil in models of plant and root growth that are responsive to soil management techniques.

Roots in the Presence of Empirical Black Holes SO ENHANCING UNDERSTANDING AND QUANTIFICATION OF SOIL-ROOT GROWTH INTERACTIONS, VOL 4 SE Advances in Agricultural Systems Modeling-Transdisciplinary Research Synthesis and Applications LA English DT Article; Book Chapter ID SEEDLINGS; PLANTS AB Plant root models are designed for understanding structural or functional aspects of root systems. When a process is not thoroughly understood, a black box object is used. However, when a process exists but empirical data do not indicate its existence, you have a black hole. The object of this research was to develop a data set, from which to model perennial ryegrass (Lolium perenne L.) root growth and development; however, three black holes were discovered. These black holes are: (i) Lolium perenne lateral roots may be determinate or indeterminate in growth depending on the clone-determinate not previously described; (ii) a dominant type of lateral root, was discovered, which initiates, seemingly randomly, grows out fast, is larger than typical lateral roots, and may be the primary adaptive basis for Lolium perenne root system response to the environment-not previously described; (iii) surface seeded or shallow seeded seedling root systems are composed of four distinct classes of root rather than three-not previously recognized. Because different root classes are functionally and developmentally distinct, it is necessary to model and study them separately. A preliminary model database is developed but needs significant improvements to adequately account for these three new root developmental patterns.

The emphasis of this chapter is on how roots affect soil structure, and how soil structure affects roots in relation to root water uptake. Roots can decrease mean soil aggregate size when growing among large peds but can increase aggregate size when aggregates are initially small. Some pioneer roots can increase the number of biopore channels after the initial roots die. Roots help maintain fractures in the soil. The former root channels become pathways for water infiltration, gas exchange, and new root growth. As roots lose water, the contact between root and soil decreases, which reduces root water uptake. Location of roots in larger preexisting root channels, in fractures, or along large ped faces may facilitate use of preferentially flowing water and allow deeper vertical root penetration to utilize wetter subsoil. Clustering of roots in macropores could reduce water uptake from the soil matrix between rains. Roots are able to proliferate in favorable soil zones and restrict growth in less favorable soil zones for efficient ratio of growth to water and nutrient utilization. The next step in modeling water uptake could include how roots alter aggregation, fractures, and biopores for future root growth. C1 [Logsdon, S.

The roles of roots are numerous, and they constitute a major pathway for the transfer of water from soil into the atmosphere. Root growth is normally genetically controlled, but a host of other factors such as the soil and the plant-plant interactions affect the overall development and distribution patterns. This chapter briefly reviews the knowledge of root growth in mixed plant systems, focusing on how root-soil interactions influence the growth processes. A conceptual framework for simulating the growth and distribution of the component plant root systems is presented, which is based on factors such as compaction, soil water distribution, root carrying capacity of different soil layers, and interspecies interactions. Though still lacking in some respects, the concept was able to simulate a range of observed root growth and water uptake patterns in a realistic manner. The proposed framework does provide a basis for further development of plant growth modeling in mixed systems. C1 [Adiku, S. G.

For anautogenous mosquito species, like A. aegypti, newly emerged adult females neither respond to host odors nor engage in blood-feeding; the bases for these behaviors are poorly understood. Here we investigated detection of two components of an attractant blend emitted by vertebrate hosts, octenol, and CO2, by female A. aegypti mosquitoes using electrophysiological, behavioral, and molecular approaches. An increase in sensitivity of octenol olfactory receptor neurons (ORNs) was correlated with an increase in odorant receptor gene (Or) expression and octenol-mediated attractive behavior from day 1 to day 6 post-emergence. While the sensitivity of octenol ORNs was maintained through day 10, behavioral responses to octenol decreased as did the ability of females to discriminate between octenol and octenol + CO2. Our results show differing age-related roles for the peripheral receptors for octenol and higher order neural processing in the behavior of female mosquitoes.

The advance of sequencing technologies has made possible the connection between phenotypes and genetic mechanisms underlying the acquisition and diversification of such traits with economic and biological significance. This chapter provides a historical view of our understanding of genomic structural variation among Fusarium species. Prior to the genomic era, chromosomal variation was observed between Fusarium species and among isolates of F. oxysporum and F. solani (teleomorph Nectria haematococca). Such observations led to the discovery of supernumerary chromosomes in Nectria haematococca MPVI and have established their role in fungus-plant interactions. Contemporary comparative genomic studies not only have confirmed the existence of supernumerary chromosomes in the F. oxysporum and F. solani genomes, but also have provided strong evidence for the horizontal transmission of these chromosomes and their role as genetic determinants of host specific virulence. Overall, knowledge of the highly dynamic Fusarium genomes establishes them as eukaryotic models allowing greater understanding of genome plasticity and adaptive evolution to ecological niches.

Contamination of grain-based food and feed with toxic SMs produced by Fusarium is associated with a variety of diseases in plants and animals and results in loss of millions of dollars in grain commodities each year. Many SMs are formed via the activities of a family of large enzymes called polyketide synthases (PKSs) that consist of between five and eight functional domains. This Chapter reviews the structures and functions of Fusarium PKSs present in four species, Fusarium verticillioides, Fusarium graminearum, Fusarium solani and Fusarium oxysporum. Each genome has between 11 and 16 PKS genes. Re-examination of inferred phylogenetic relationships of deduced amino acid sequences provides insight into how this gene family evolved. The geneaologies suggest that collectively the Fusarium PKSs represent 36 distinct sets of PKS homologues, where each set catalyses synthesis of a structurally distinct polyketide. Variation in Fusarium PKS genes is due to both ancient and recent gene duplications, gene loss events, gain-of-function due to the acquisition of new domains, and of loss-of-function due to nucleotide mutations. The significant number and variety of evolutionary changes reflects a vast biosynthetic potential this gene family provides fungi and that may help them adapt to changing environmental conditions. Understanding how fungal polyketides are synthesized should lead to better methods to control their production and thereby reduce their negative impact on human endevors.

Historically various molecular fingerprinting techniques mainly RFLPs, RAPDs, SCARs, AFLPs, and SSRs successively contributed for identification of stone fruit germplasm, characterization of its genetic diversity, and assistance in depicting distinctness, uniformity and stability (DUS) of cultivars. AFLPs and SRRs both generate the highest-resolution patterns to identify cultivars in species with a very low polymorphism such as peach. Nevertheless, SSRs, as the most transportable markers across species, are now a preferred technique for marker-assisted breeding (MAB) in stone fruits, particularly peach, apricot and almond. Breeding programs primarily rely on the evaluation of genetic diversity of collection of material before choosing the parental material that will allow to maximize this diversity for subsequent optimal combination. The online release of the peach genome sequence has opened up the way to a huge step forward by giving a direct access to all genomic data and particularly to multiple new SSR loci as an optimal tool for improved germplasm characterization. In Prunus spp. a diversification of markers, which is mainly based on gene sequences (SNPs, RGAs, CGAs) and gene expression (ESTs), is now in progress. Current examples of MAB relate to very diverse features including columnar growth habit, self-incompatibility, environmental adaptation, resistance to biotic stresses such as green peach aphid (Myzus persicae), sharka (Plum pox virus-PPV), powdery mildew, peach tree short life (PTSL), and root-knot nematodes (RKN). In this context, one of the predominant goals of MAB is to promote gene pyramiding as a guarantee for resistance durability to biotic stresses. A first example is the ongoing breeding strategy for RKN resistance in Prunus rootstocks, which is based on pyramiding of the major genes Ma (plum), RMia (peach) and RMja (almond) in order to confer a high-level, wide-spectrum and heat-stable resistance. Another example is the Fruit Breedomics project that focused notably on several genes or QTLs for resistance to peach green aphid and powdery mildew. In the near future, new MAB challenge will be to emphasize on the selection at the genome level and develop genome-wide association mapping (linkage disequilibrium studies) enabling genome-wide surveys of variability based on markers evolving from SSRs to SNPs. Due to the availability of peach genome sequence, molecular breeding will rely more and more on peach as a model species for stone fruits. Investigations aiming at developing transgenic breeding of stone fruits report Agrobacterium tumefaciens-mediated transformation of both mature and juvenile tissues. However successful transformation and regeneration of commercial cultivars are still far from routine and are limited to a few genotypes or to seedlings. Thus transgenic breeding efforts focus on solving major bottlenecks, e.g., the recalcitrance to regenerate adventitious shoots from clonal tissues such as leaf explants and the long (3 to 10 years) juvenile period in obtaining transgenic stone fruits. Nevertheless, PPV-resistant transgenic plum has been produced that is now deregulated for commercial planting in USA.

TI Predicting Eurasian watermilfoil's (Myriophyllum spicatum) distribution and its likely response to biological control in a spring-fed river SO JOURNAL OF AQUATIC PLANT MANAGEMENT LA English DT Article DE river plants; invasion; biological control; predictive aquatic plant management AB Controlling invasive aquatic plants would benefit from development of predictive theories that can be used to set priorities for when, where, and how to manage these species. The invasion of Eurasian watermilfoil (Myriophyllum spicalum L.) into a northern California river provides an opportunity to apply predictive relationships for it and its management. To test a hypothesis (from the scientific literature) regarding habitat. susceptibility to Eurasian watermilfoil invasion and evaluate prospects for its management, we collected water quality, temperature, and plant data from Fall River. During 2009 and 2010 we determined Eurasian watermilfoil abundance and distribution at 71 locations within the river from an upstream to downstream direction. We also determined water temperature and total phosphorus (P) concentration. Eurasian watermilfoil frequency increased in the river downstream from the confluence of Spring Creek. Based on measured total P concentrations and simulations from a physiologically based growth model, Eurasian watermilfoil should be able to grow upstream of this point. as well, High water levels which prevent boats from passing under the bridge located at this point may limit the upstream spread of Eurasian watermilfoil. One proposal is to introduce the Eurasian watermilfoil weevil (Euhryciopsis lecontei Dietz) as a biological control agent. In other habitats the weevil has been most successful when 3 or more generations of weevils are produced each year. Degree-day calculations using Fall River water temperatures and 2 scenarios for weevil growth and development indicate that the weevil only achieves 3 or more generations per growing season at points downstream of the confluence of the Title River. This represents the downstream one-third of the river. This information, in conjunction with simulations from a published model on the weevil/milfoil interaction, suggest that it is not likely that the milfoil weevil will reduce Eurasian watermilfoil biomass in Fall River.

TI Release and evaluation of Cyrtobagous salviniae on common salvinia in southern Louisiana SO JOURNAL OF AQUATIC PLANT MANAGEMENT LA English DT Article DE Salvinia minima; Cyrtobagons salviniae; biological control; aquatic weeds AB Common salvinia (Salvinia minute) is one of the most widespread, non-native invasive species at the :Barataria Preserve of Jean Lafitte National Historical Park and Preserve in southern Louisiana and currently infests more than 3,600 ha and 48 km of navigable waterways. A proven biological control agent, the salvinia weevil (Cyrtobagous salviniae Calder and Sands), was field collected on S.minima in Florida, checked for pathogens, and then released in the Preserve from June 2002 through June 2005. Few weevils were recovered front heavily shaded sites when compared to full sun sites where weevils were recovered frequently. Plant biomass and percent cover were reduced only in full sun sites. A field nursery site was established at an undisturbed location in Twin Canals in June 2003 and stocked with 2,421 weevils, released periodically until August 2005. Although weevils, including teneral adults, were recovered at all but one release site, population establishment was not confirmed during this period because of multiple perturbations, culminating in Hurricane Katrina, which caused large scale saltwater intrusion which temporarily destroyed all the sites near the end of the project. However, recent weevil detections by other researchers suggest that the weevils did establish in the area. Any future research efforts in this region should focus on identifying full sun, undisturbed sites to expedite establishment and evaluate impact. C1 [Tipping, Philip W.; Madeira, P. T.; Center, T.

Techniques can range from complex fixed structures to field site selection, to straightforward cultural practices in the field. This introduction to the ASHS workshop "Protected cultivation for fruit crops" considers techniques of protected cultivation in the broad sense. The text presents the physical principles associated with protected cultivation, namely heat transfer to and from the crop as expressed by the surface energy balance concept. Common terminology is introduced with respect to spatial and temporal scales. The four modes of heat transfer arc discussed via the energy balance equation: radiation, convection, conduction, and latent heat fluxes. Illustrative examples of current practices in protected cultivation are provided in the context of the aforementioned physical principles. C1 USDA ARS, Hort Crops Res Unit, Prosser, WA 99350 USA.

JHAs disrupt a hormonal system that is specific to insects and thus kill some target pests while causing less harm to nontarget organisms than broad-spectrum insecticides. JHAs have become increasingly important in agriculture worldwide, where their specificity and efficacy has been used selectively to reduce target pest populations while conserving key natural enemies. Evolution of resistance by target pests, however, can reduce the effectiveness of JHAs. This chapter reviews how models have been used to analyze the evolution of pest resistance to JHAs and to develop strategies to delay pest resistance. We describe results of general mathematical models and a case study showing how simulation, conceptual, and spatially explicit statistical models have been applied to better understand and manage evolution of resistance to the JHA pyriproxyfen by the whitefly, Bemisia tabaci. Our results show how genetic, ecological, and human factors affect evolution of pest resistance to JHAs. Integrating knowledge of these factors into models can help to produce useful predictions about pest resistance to JHAs and to improve management strategies for preserving the effectiveness of this important functional class of insecticides.

TI The maize rachis affects Aspergillus flavus spread during ear development SO MAYDICA LA English DT Article DE Zea mays; rachis; Aspergillus flavus; fluorescence microscopy AB Aspergillus flavus that transgenically expressed the green fluorescent protein was used to follow infection in ears of maize hybrids resistant and susceptible to the fungus. Developing ears were needle-inoculated with GFP-transformed A. flavus 20 days after silk emergence, and GFP fluorescence in the pith was evaluated at 1, 2, 3, 4, 5, 10, and 20 days after inoculation. Fluorescence levels in the pith of susceptible lines were significantly higher (P < 0.0001) than in resistant lines at all time points. Pith sections apical to the inoculation point displayed higher fluorescence levels compared to other sections of the ear, suggesting fungal spread via the water/nutrient transport system. Fluorescence levels in resistant lines did not change significantly over time, implying spread of the fungus but not growth. Fluorescence in susceptible ears was highest at early time points, suggesting that conditions were more conducive to spread than at the later time points. These results suggest that the rachis could retard the spread and/or growth of the fungus inside the developing maize ear. Although fluorescence was observed in kernels from resistant ears, it occurred at a much higher frequency in those from susceptible hybrids. Together, these results suggest that the rachis is used by maize as a defense structure similar to other preformed types of resistance.

To measure NH3 volatilization from wetlands, enclosure methods are preferred when site conditions preclude micrometeorological techniques. This chapter describes a wind tunnel enclosure to measure NH3 volatilization. The tunnel system is open ended and incorporates the following design elements: (i) a tunnel-shaped working section to enclose the experimental plot (including wetland plants), (ii) variable-speed fan(s) or blower(s) to generate airflow through the tunnel, (iii) airflow conditioning sections, and (iv) a structure to produce laminar airflow. The size of the tunnel and materials used in its construction are dictated by the site conditions. Air flow through the tunnel is monitored with anemometers. Sampling of NH3 is accomplished by using vacuum pumps to pass a known proportion of the air entering and exiting the tunnel through an acid that will absorb the NH3. The rate of volatilization is calculated using the amount of sampled NH3, the ratio of airflow rate to sampling rate, and the sampling duration. C1 [Poach, M.

Because of the differences in toxicity and adsorption behavior, determinations of the redox states arsenite, As(III), and arsenate, As(V), and selenite, Se(IV), and selenate, Se(VI), are important. Anion exchange chromatography is used to separate As(III) and As(V) or Se(IV) and Se(VI) based on differences in retention times. Samples are then mixed with concentrated HCl for As or Se determination as the hydrides. Detection limits are 0.8 mg L-1 As for both redox states, 0.68 mg L-1 for Se(IV), and 0.55 mg L-1 for Se(VI). Spiking of actual mixed sample solutions of both redox states showed the procedure to be accurate for solutions with As(III)/As(V) or Se(IV)/Se(VI) ratios ranging from 1:4 to 4:1. Average recoveries were 95.7% for As (III), 106% for As(V), 93.1% for Se(IV), and 108% for Se(VI).

TI Estimation of viral richness from shotgun metagenomes using a frequency count approach SO MICROBIOME LA English DT Article DE Phage; Metagenomics; Virome; Ecology; Richness; CatchAll; Singleton AB Background: Viruses are important drivers of ecosystem functions, yet little is known about the vast majority of viruses. Viral shotgun metagenomics enables the investigation of broad ecological questions in phage communities. One ecological characteristic is species richness, which is the number of different species in a community. Viruses do not have a phylogenetic marker analogous to the bacterial 16S rRNA gene with which to estimate richness, and so contig spectra are employed to measure the number of virus taxa in a given community. A contig spectrum is generated from a viral shotgun metagenome by assembling the random sequence reads into groups of sequences that overlap (contigs) and counting the number of sequences that group within each contig. Current tools available to analyze contig spectra to estimate phage richness are limited by relying on rank-abundance data. Results: We present statistical estimates of virus richness from contig spectra. The program CatchAll (http://www.northeastern.edu/catchall/) was used to analyze contig spectra in terms of frequency count data rather than rankabundance, thus enabling formal statistical analyses. Also, the influence of potentially spurious low-frequency counts on richness estimates was minimized by two methods, empirical and statistical. The results show greater estimates of viral richness than previous calculations in nearly all environments analyzed, including swine feces and reclaimed fresh water. Conclusions: CatchAll yielded consistent estimates of richness across viral metagenomes from the same or similar environments. Additionally, analysis of pooled viral metagenomes from different environments via mixed contig spectra resulted in greater richness estimates than those of the component metagenomes. Using CatchAll to analyze contig spectra will improve estimations of richness from viral shotgun metagenomes, particularly from large datasets, by providing statistical measures of richness.

We combined avian survey data collected from three studies spanning a 16-year period on a small island with a minimal human presence in the British Virgin Islands. Although abundances varied among surveys, the same species were detected with rare exceptions. Despite stability in species composition, the resident landbirds were variable in their individual detectabilities. Survey detections relatively mirrored net captures for some species, but are quite different for others. We suspect that this is likely due to differences in detectability due to species-specific behaviors mediated by environmental conditions, such as rainfall, during the month or months prior to our surveys. It is difficult to assess the influence of timing or amount of precipitation on bird detections rates among our surveys due to a lack of consistent collection of location-specific weather data in the British Virgin Islands. Our study suggests monitoring efforts conducted in concert with collection of site-specific climate data would facilitate improved interpretation of survey data and a better understanding of avian species response to climate mediated changes.

Thus, this region mostly located in the Midwestern USA, provides a natural location for research on how intensive agriculture for food, feed and biofuel production can coexist with a healthy environment. The use of a process-based hydrologic and water quality model is considered indispensable to address this objective at such a large spatial scale. An integrated modeling system has been constructed with the hydrologic Soil and Water Assessment Tool (SWAT) model (see Part 1 paper describing overall modeling system), capable of estimating river basin responses to alternative cropping and/or management strategies. To facilitate the identification of optimum locations for a cost-effective river basin management, this SWAT large-scale application incorporates a greatly refined subwatershed structure based on the 12-digit hydrologic units (subwatersheds), while the land phase of the hydrologic and nutrient cycles are calculated at thousands of Hydrologic Response Units, which represent unique combinations of land, soil and topographical features. However, given the very large scale and the need to ensure the reliability of flow and pollutant load predictions at various locations within such hydrologic systems, a model's calibration becomes a time-demanding and challenging task. The purpose of the current article is to demonstrate a semi-automatic calibration approach for large-scale and spatially detailed modeling studies, with the use of the Sequential Uncertainty Fitting algorithm (SUFI-2) and the SWAT-CUP interface developed exclusively for SWAT hydrologic projects. The calibration framework provides estimates of the uncertainty of predictions at various locations and can be finalized within a reasonable timeframe with a powerful personal computer (PC). This study presents the whole calibration approach providing guidance on similar efforts at the regional scale.

They play an important role in providing forage for livestock and wildlife, and they serve as critical watershed areas. Many of the world's rangelands have been degraded by overgrazing, marginal crop production, mineral and energy extraction, recreation, and other human-caused disturbances. This degradation has led to invasion by exotic weeds and subsequent increases in fire frequency. This, in combination with uncertainties associated with global climatic change, has resulted in a critical need for plant materials to restore and revegetate rangeland ecosystems. The assessment of genetic variation and its phenotypic expression in important rangeland plant species (especially forbs) is critical in defining population structures (genetically differentiated groups) that could be used in rangeland restoration/revegetation efforts. We used common-garden studies and DNA-based analysis of genetic variation to assess genetic diversity in three rangeland legume species indigenous to rangeland ecosystems of the Great Basin Region of the western USA. Results of these studies are presented as three case studies that describe data collection procedures, analysis, and interpretation used to identify population structures in each species. These data formed the basis for combining plant collections into geographically based metapopulations for these three legume species that are being used to develop plant materials for commercial seed production and subsequent use on rangelands of the Great Basin.

Stability of soil structure describes the ability of the soil to retain its arrangement of solid and pore space (i.e., aggregates and pores) when exposed to external forces (e.g., tillage, cropping, compaction and irrigation). Studying the effects of agricultural management practices on soil structure is important for the development of effective soil conservation practices to avoid risks of soil deterioration. The current review presents and discusses results of water retention curves at near saturation (matric potential, psi, 0 to -5 J kg(-1)) obtained by the High Energy Moisture Characteristic (HEMC) method for >200 soil samples from humid and arid zones. Quantifying differences in the water retention curves using the modified van Genuchten model (Soil-HEMC) yielded soil structure indices which were then used to elucidate in quantitative terms possible interactions among soil physical processes and management practices. Analyses of the water retention curves indicated that kaolinitic humid zone soils are (i) more stable than smectitc semiarid zone soils, and (ii) less sensitive to management, soil texture, organic matter content and wetting rate. Parameters of the van Genuchten model were successfully employed for evaluation of the contribution of large (>0.25-0.50 mm) and small (<0.25-0.50 mm) aggregates/particles to the pore size distribution and soil structure condition. The presented detailed analyses of the contribution of soil inherent properties and extrinsic conditions (e.g., spatiotemporal variation) to inter-and intra-aggregate porosity, the soil structure indices and model parameters at near saturation, sheds additional light on the processes that are involved in stabilizing soil structure, and may assist in developing more efficient soil and environment management practices.

Column leaching studies provide insight into chemical processes in waste rock dumps and pit backfills and can be used to predict metal mobility. This information can be used to improve the design and environmental performance of waste rock disposal facilities. This paper presents recommendations for development of a standard column testing method that will help ensure that leaching tests provide comparable data consistent with observed seepage chemistry from full-scale mine facilities in the Southeast Idaho Phosphate District.

Strains were grown in malt extract (ME) basal medium containing 1% (w/v) distiller's dried grains with solubles (DDGS), an abundant coproduct of fuel ethanol production by the dry grind process. Ten of 11 strains tested produced more than 2 g schizophyllan/L. Two strains, ATCC 20165 and CBS 266.60, produced more than 10 g schizophyllan/L. Schizophyllan from these strains was similar to commercial product in terms of solution viscosity, molecular weight, and surface tension properties, suggesting that they would be equivalent in biomaterial applications.

TI Soil moisture affects fatty acids and oil quality parameters in peanut SO INTERNATIONAL JOURNAL OF PLANT PRODUCTION LA English DT Article DE Arachis hypogaea L.; Drought stress; O/L ratio; Iodine value ID ARACHIS-HYPOGAEA L; HIGH OLEIC-ACID; AFLATOXIN CONTAMINATION; OXIDATIVE STABILITY; SEED COMPOSITION; N-2 FIXATION; DROUGHT; GENOTYPES; ASSOCIATION; TEMPERATURE AB Drought affects yield of peanut, but its effect on oleic and linoleic acids that influence its oil quality of peanut genotypes with different levels of drought resistance has not been clearly investigated. Therefore, the aims of this research were to determine whether soil water levels could affect oil quality by changes in fatty acid compositions of peanut, and to investigate the changes in oil characters in peanut genotypes with their potential drought resistance under different water regimes. Field experiments were conducted in split-plot designs with four replications during dry season for two years (2003/04 and 2004/05). Three water regimes [field capacity (PC), 2/3 available soil water (2/3 AW) and 1/3 available soil water (1/3 AW)] were assigned as main-plots, and six peanut genotypes were assigned as sub-plots. The data were recorded at maturity for fatty acid compositions and % oil. Seed samples were analyzed for % oil by Soxtec System HT, and fatty acid compositions were analyzed by gas liquid chromatography. Differences among water regimes and peanut genotypes were significant for oleic and linoleic acids content and their ratio (OIL ratio), unsaturated to saturated fatty acid ratio (U/S ratio) and iodine value (IV). Genotype x water regime interactions were also significant for all characters. Drought improved the oil quality by significant increase in oleic acid and OIL ratio, and reduced the linoleic acid, IV and U/S ratio. Peanut genotypes with different levels of drought resistance displayed similar tendency in fatty acid characters under drought conditions.

TI Calibration and use of plate meter regressions for pasture mass estimation in an Appalachian silvopasture SO ARCHIVES OF AGRONOMY AND SOIL SCIENCE LA English DT Article DE forage; pasture mass; plate height; ruler height; tall fescue; orchardgrass ID HERBAGE YIELD; DISK METER; HEIGHT; TRIALS AB A plate meter for measuring pasture mass was calibrated at Agroforestry Research Site in Blacksburg, Virginia, USA, using six ungrazed plots of established tall fescue overseeded with orchardgrass. Each plot was interplanted with bare root honey locust and black walnut seedlings spaced along a gradient ranging from 1.8 to 11.0 m. Plate height (PH) of forage between trees was measured by placing a 46-mm x 46-mm x 5.6-mm-thick acrylic plastic plate meter on pasture canopy at six locations four times a season. PH was measured between ground and plate as it rested on pasture canopy. To calibrate the plate meter against a known dry matter yield, 50 x 50-cm clip plots followed each PH measurement. The resulting regression slope was 421 kg ha(-1) cm(-1), with an r(2) value of 0.86. Unique research investigating the response of forage mass to site elevation is presented using the developed equation. The field-calibrated regression slope of ruler height (RH) to PH was 1.71 cm cm(-1), with an r(2) value of 0.87, showing good correlation between RH and PH. A comparable regional regression equation was found to adequately predict independent calibration clip plot data reported at this site. The results support the application of regression equations for estimating pasture mass in areas having similar climates and pasture composition. C1 [Dougherty, Mark; AbdelGadir, A.

The fire ant decapitating fly Pseudacteon obtusus Borgmeier (Diptera: Phoridae) was released as a biocontrol agent of the red imported fire ant (Solenopsis invicta Buren) in Gainesville, FL because it is a common parasitoid of this ant in Argentina and because it has a higher propensity of attacking fire ants along foraging trails than the two Pseudacteon species previously released. Field surveys of a rapidly expanding P. obtusus population (8-12 km/yr) proved that this fly was capable of thriving and successfully competing with the much more abundant Pseudacteon curvatus Borgmeier. However, Pseudacteon tricuspis Borgmeier, the first decapitating fly released, was effectively excluded from most sample sites when faced with competition from both P. curvatus and the similar-sized P. obtusus. Despite clear evidence for competitive exclusion, P. tricuspis abundance at sample sites was positively correlated with the abundance of its two competitors-probably because of moderate to strong covariability in the suitability of sample sites for all three congeners. The addition of P. curvatus, the second parasitoid released, increased total parasitism pressure on fire ant populations by about 10-fold. The addition of P. obtusus, the third species, did not measurably improve total guild parasitism rates on imported fire ants in North Central Florida (as assessed by roadside trap counts), but the performance of this species will likely vary with habitat, region, and climate.

We utilized a spatially explicit, resource-selection function to evaluate its distribution relative to landscape composition and structure at local (within home-range) and broad (home-range selection) spatial scales, followed by a moving-window analysis to model patch occupancy across this landscape. We found strong support for the influence of type, size, and compositional elements: large, old-growth patches were selected at both spatial scales, and regenerating forest patches <= 40 yrs old were selected against at the broader scale. More importantly, we found that occupancy was related to critical thresholds in composition: patches required >= 73% old-growth forest cover or a minimum total area of 73 ha of old-growth forest to be occupied by flying squirrels. A non-uniform pattern of selection for patches with higher structural connectivity at the local scale, but not at the broader scale, was likely a result of the "empty forest" phenomenon, in which remnant patches were inaccessible in this fragmented landscape. These results are consistent with recent studies of this and related species and suggest that occurrence of northern flying squirrels in southeastern Alaska is influenced by a number of landscape structure and compositional variables that relate critically to late-seral forest conditions. These findings shed new light on the utility of this species as an ecological indicator and its functional relevance to the resilience of fragmented forest ecosystems. (C) 2012 Elsevier Ltd.

Co-planting with castor decreased the shoot biomass of S. alfredii as compared to that in monoculture. Cadmium concentration in S. alfredii shoot significantly decreased when grown with ryegrass or castor as compared to that in monoculture. However, no reduction of Zn or Pb concentration in S. alfredii shoot was detected in co-planting treatments. Total removal of either Cd, Zn, or Pb by plants was similar across S. alfredii monoculture or co-planting with ryegrass or castor, except enhanced Pb removal in S. alfredii and ryegrass co-planting treatment. Co-planting of S. alfredii with ryegrass or castor significantly enhanced the pyrene and anthracene dissipation as compared to that in the bare soil or S. alfredii monoculture. This appears to be due to the increased soil microbial population and activities in both co-planting treatments. Co-planting of S. alfredii with ryegrass or castor provides a promising strategy to mitigate both metal and PAH contaminants from co-contaminated soils.

We searched the ISI Web of Science, Scopus, SciELO, and Google Scholar databases and in recent theses and dissertations to obtain the following information: latitude, longitude, city, states, length of record (years). altitude, precipitation. R factor, equations calculated and respective determination coefficient (R-2). We found 35 studies in Brazil that used pluviographic rainfall data to calculate the rainfall erosivity. These studies were concentrated in the cities of the south and southeast regions (similar to 60% of all the cities studied in Brazil) with a few studies in other regions, mainly in the north. The annual rainfall erosivity in Brazil ranged from 1672 to 22,452 MJ mm ha(-1) h(-1) yr(-1). The lowest values were found in the northeast region, and the highest values were found in the north region. The rainfall erosivity tends to increase from east to west, particularly in the northern part of the country. In Brazil, there are 73 regression equations to calculate erosivity. These equations can be useful to map rainfall erosivity for the entire country. To this end, techniques already established in Brazil may be used for the interpolation of rainfall erosivity, such as geostatistics and artificial neural networks. (C) 2012 Elsevier B.V.

Increased biomass and Ni phytoextraction efficiency is useful to achieve economically viable phytomining. The objective of this study was to evaluate the effect of two types of phytohormones on the Ni phytoextraction capacity of four Alyssum species. Two different commercially available phytohormones (Cytokin (R) and Promalin (R)) based on cytokinins and/or gibberellins were applied on shoot biomass of four Ni hyperaccumulating Alyssum species (A. corsicum, A. malacitanum, A. murale, and A. pintodasilvae). Cytokin was applied in two concentrations and promalin in one concentration. The application of phytohormones had no clear positive effect on biomass production, Ni accumulation and Ni phytoextraction efficiency in the studied Alyssum species. A. malacitanum was the only species in which a significantly negative effect of these treatments was observed (in Ni uptake). A slightly positive response to promalin treatment was observed in the biomass production and Ni phytoextraction efficiency of A. corsicum. Although this effect was not significant it does indicate a potential application of these approaches to improve phytoextraction ability. Further studies will be needed to identify the most adequate phytohormone treatment as well as the appropriate concentrations and application times. C1 [Cabello-Conejo, M. I.; Kidd, P.

This creates a major problem in the production and specificity verification of diagnostic anti-Ig reagents for the vast majority of mammals. We describe a novel solution using the swine system with its eleven different variants of IgG. It involves the in vitro synthesis of chimeric porcine-camelid heavy chain antibodies (HCAbs) that do not require light chains and therefore only a single transfection vector. The expressed chimeric HCAbs are comprised of the camelid VHH domain encoding specificity for lysozyme and the hinge, CH2 and CH3 domains of the various porcine IgGs. These HCAb retain their antigenic integrity and their ability to recognize lysozyme. The engineered specificity assures that these HCAb can be immobilized in native configuration when used for testing the specificity of anti-swine IgG antibodies. Comparative data to illustrate the importance of this point are provided. These are now available for use in hybridoma selection and as reference standards for evaluating the specificity of currently available anti-swine IgG antibodies. (C) 2012 Elsevier Ltd.

The Maillard reaction products (MRPs) prepared with rice protein hydrolysates at 5% degree (hydrolysed by Protease N) and dextran T20 (20 min at 100 degrees C) showed the greatest improvement in functionality. The solubility, emulsification activity (EA), and emulsification stability (ES) of the MRPs increased by factors of 3.5, 5.3 and 7.3 times, respectively as compared to MRPs formed with native rice proteins and dextran T20. Amino acid analysis indicated that lysine and arginine decreased significantly in the MRPs. Formation of MRPs reduced the surface hydrophobicity, which was in agreement with the change of solubility. However, further decreasing of the surface hydrophobicity resulted in lower EA and ES during the late stage of the reaction. Fluorescence analysis suggested that formation of late stage MRPs occurred after 20 min of the Maillard reaction. The molecular weight distributions showed that the functional properties of MRPs and the mechanisms of formation were affected by the peptide chain length. (C) 2012 Elsevier Ltd. All rights reserved.

Fresh apple imports in the United Kingdom provide a perfect case of this particular problem due to periodic trade. In this study, the differenced version of the almost ideal demand system is employed for estimating import demand by source and an iterative procedure is developed for deriving choke prices (prices at which imports are zero) and import demand estimates. The appeal of this procedure is that the final estimates and choke prices are not sensitive to the starting values used for the initial estimation. When comparing the results of the choke price procedure to a more traditional approach of eliminating zeros by aggregating across countries, significant differences emerge. Results clearly show that the aggregate estimates do not adequately reflect the pattern of UK imports from seasonal suppliers. C1 Econ Res Serv, Markets & Trade Econ Div, USDA, Washington, DC USA.

The fruit has a sweet, exotic flavor and is rich in vitamins A and C and antioxidants. However, due to its highly perishable nature, it has not emerged as a major traded fruit. Papayas are highly susceptible to qualitative and quantitative postharvest losses. Maintenance of papaya fruit quality during the supply chain depends on orchard management, harvesting practices, packing operations, postharvest treatments, temperature management, and transportation and storage conditions. Postharvest losses are attributed to mechanical damage, rapid flesh softening, decay, physiological disorders, pest infestation, and improper temperature management. The aim of postharvest technology and management in the supply chain is to provide favorable conditions to extend storage life and retain quality and nutritional attributes. This review focuses on the available research findings to retain overall papaya fruit quality and to reduce postharvest losses during the supply chain via adopting appropriate or novel postharvest technologies.

Contemporary milling techniques produce a flour similar to that of indigenous peoples that is about 40% sucrose, 25% dietary fiber, and that has a variety of volatiles, such as 2,6-dimethylpyrazine, gamma-nonalactone, methyl salicylate, and 5,6-dihydro-6-propyl-2H-pyran-2-one, that contribute to a chocolate and coconut-like aroma. Flour made from the mesocarp contains no stachyose or raffinose, sugars that are responsible for flatulence in other legumes. High-performance liquid chromatography (HPLC) analyses of sugar (sucrose) and citric, malic, and ascorbic acids found considerable ranges in acid/sugar ratio that may be responsible for the wide variations in organoleptic perception. Due to the absence of gliadin, peanut, and soy allergens, the flour is useful in gluten-free formulations. Optimum concentrations for incorporation ranged from 5% for biscuits, 10% for breads, 15% for pancakes/muffins, and 50% in chapatti and drum-dried wheat flour. At these concentrations, considerable browning occurs, which is generally considered to be desirable. C1 [Felker, Peter] Casa Mesquite, Hollister, CA 95023 USA.

SO APPLIED ECONOMICS LA English DT Article DE CGE model; trade flows; tariff removal; density functions ID DEVELOPING-COUNTRIES; DEVELOPMENT SPILLOVERS; GROWTH; OPENNESS AB Despite a number of multi-country case studies based on a variety of analytical frameworks and numerous econometric studies using large cross-country data sets that analyse trade openness and its induced economic activities that alters both the volume and value of trade flows, there is still disagreement among economists concerning the nature of this relationship. In this article, we follow a rather unique approach by estimating the density functions of the observed trade flows and the density functions of trade flows generated by tariff removal using an intertemporal global Computable General Equilibrium (CGE) model. Our inquiry is whether or not the trade flows generated by global tariff elimination impact economies in the long-run and alter their historical underlying distributions. If the latter case prevails, it implies that the economies follow a different transitional path into a new steady-state equilibrium. The density functions, estimated parameters and higher moments of the observed trade flow distributions are distinctly different from the parameter estimates of the trade flows generated by the model. In this sense, trade-inducing economic activity as generated by tariff removal and captured by the neoclassical specification of the model is associated with trade flows along a different transitional path from the observed trade flows.

MOTIA BURK.; CYMBOPOGON-MARTINII; HARVEST TIME; PEPPERMINT PRODUCTIVITY; QUALITY; NITROGEN; PIPERITA; STAGE AB Altering the distillation times of economically important essential oils such as peppermint (Mentha x piperita L), lemongrass (Cymbopogon flexuosus Steud.), and palmarosa (Cymbopogon martini( Roxb.) oils may allow producers to increase the production, engineer the composition, and decrease the energy required for distillation. Experiments were conducted to model essential oil yield and oil composition of peppermint, lemongrass, and palmarosa oils as a function of the length of the steam distillation time (DT). Maximum essential oil yields of peppermint, lemongrass, and palmarosa were achieved at a DT of 20 min: further increases in DT did not increase oil yields. In lemongrass and palmarosa experiments. DTs of 240 min led to 25-40% reductions in oil yield compared to yields at 20-160 min. This study demonstrated that DT can be used as a tool for obtaining essential oils with specific targeted composition from peppermint, lemongrass, and palmarosa. Secondly, the study found that the optimum length of the DT for maximum essential oil yields of peppermint, lemongrass, and palmarosa was much shorter than the time usually used by researchers and processors. Shorter DT may save producers and processors energy costs and other resources. This study also suggests that comparison of data on oil composition must take into consideration the length of the DT.

The results show the IB strength increased about 9.6% and 13.4% for steam-treated MDF (PC) and OA-treated MDF compared with raw control panels, while OA pretreatment has a slight negative effect on the bending properties of MDF. Generally, the steam-treated and OA-treated panels exhibit a slightly improved dimensional stability, but the difference is not significant compared with raw control panels. The thermo-mechanical defibration process is the main factor to improve the bond-ability between UF resin and rice straw, which resulted in good quality rice straw MDF. The mechanical strength of rice straw MDF can meet ANSI standard for interior MDF, but the LE and TS of MDF without paraffin wax addition is lower than the minimal requirement of the ANSI standard. MDF is one of the most feasible products for utilizing rice straw. (C) 2012 Elsevier B.V. All rights reserved.

The resulting polymers (RPEuO) were characterized by FTIR, H-1 NMR, C-13 NMR, solid state C-13 NMR spectroscopies, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and gel permeation chromatography (GPC). The results indicated that the ring-opening polymerization of EuO occurred at mild conditions, such as at room temperature, and a subcritical carbon dioxide (CO2) pressure of 65.5 bar. The formed RPEuO materials were cross-linked polymers. The glass transition temperatures of these polymers ranged from -15.0 to 22.7 degrees C. TGA results showed that the RPEuO polymers were thermally stable at temperatures lower than 220 degrees C and significant decomposition mainly occurred above 340 degrees C. Published by Elsevier B.V.

TI Extraction of proteins from pennycress seeds and press cake SO INDUSTRIAL CROPS AND PRODUCTS LA English DT Article DE Pennycress; Protein extraction; Biodiesel; Calorimetry ID THLASPI-ARVENSE L.; CIRCULAR-DICHROISM; STORAGE PROTEINS; ADHESIVES; FRACTIONATION; PRODUCTS; PLANTS; ZEIN; OIL AB In order to more fully utilize pennycress. a potentially viable bio-diesel source, the proteinaceous components were extracted from pennycress seeds and press cake. The amino acid composition of the proteins present in pennycress was typical for proteins derived from plants, with glycine, glutamic acid and alanine being prevalent. Water, 0.5 M sodium chloride, 60% acetic acid. 0.1 M sodium hydroxide and ethanol were used in sequential order to remove the protein from pennycress seeds and press cake and determine the various soluble protein fractions. Extraction temperature was varied from 5 to 77 degrees C. The highest yield of material (35%) was obtained by extracting pennycress seeds with water at 77 degrees C. However, this material had only moderate levels of protein (25%) with the remainder being carbohydrates and oil (as determined by infrared spectroscopy). The use of 0.5 M sodium chloride to remove protein from press cake at 5 degrees C produced material with the highest protein content (83%), but extraction yield was 25%. When extractions were carried out at 77 degrees C, oil typically began to be a major impurity in the protein. Using bomb calorimetry, the material remaining after extraction was found to have some value as a fuel source. Published by Elsevier B.V.

Artemisinin is also effective against helminthic and protozoan parasites that afflict both humans and livestock. Besides being the only commercial source of artemisinin, the plant contains a pleasantly aromatic essential oil valued in perfumery and cosmetics. However, multi-use of the leaf biomass for the production of artemisinin, essential oil, and antioxidants has never been investigated. The objectives of this research were to evaluate the effect of distillation time of A. annua biomass on essential oil yield, artemisinin concentration, and antioxidant capacity of the plant residue from distillation (PRD). Results demonstrated that leaf biomass can be explored for both essential oil and as a source of antioxidants, but the PRD is devoid of artemisinin. The high antioxidant capacity of the PRD (75% of the control samples) suggests that the industrial byproduct used to produce the essential oil is also a potential source of antioxidants for use as a livestock feed supplement or as a source of compounds for the nutraceuticals market.

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

S. aureus causing bovine mastitis yields high annual losses to the dairy industry. Conventional treatment of mastitis by broad range antibiotics is often not successful and may contribute to development of antibiotic resistance. Bacteriophage endolysins present a promising new source of antimicrobials. The endolysin of prophage Phi SH2 of Staphylococcus haemolyticus strain JCSC1435 (Phi SH2 lysin) is a peptidoglycan hydrolase consisting of two catalytic domains (CHAP and amidase) and an SH3b cell wall binding domain. In this work, we demonstrated its lytic activity against live staphylococcal cells and investigated the contribution of each functional module to bacterial lysis by testing a series of deletion constructs in zymograms and turbidity reduction assays. The CHAP domain exhibited three-fold higher activity than the full length protein and optimum activity in physiological saline. This activity was further enhanced by the presence of bivalent calcium ions. The SH3b domain was shown to be required for full activity of the complete Phi SH2 lysin. The full length enzyme and the CHAP domain showed activity against multiple staphylococcal strains, including MRSA strains, mastitis isolates, and CoNS. Published by Elsevier B.V.

TI Estimating the economic value of cultural ecosystem services in an urbanizing area using hedonic pricing SO JOURNAL OF ENVIRONMENTAL MANAGEMENT LA English DT Article DE Ecosystem services; Economic valuation; Hedonic pricing; Spatial econometrics ID RESIDENTIAL PROPERTY-VALUES; OPEN SPACE; GREEN SPACE; LAND-USE; UNITED-STATES; ENVIRONMENTAL-QUALITY; CONTINGENT-VALUATION; LANDSCAPE AMENITIES; HOUSE PRICES; FOREST AB A need exists to increase both knowledge and recognition of the values associated with ecosystem services and amenities. This article explores the use of hedonic pricing as a tool for eliciting these values. We take a case study approach, valuing several services provided by ecosystems, namely aesthetic quality (views), access to outdoor recreation, and the benefits provided by tree cover in Dakota County, Minnesota, USA. Our results indicate that these services are valued by local residents and that hedonic pricing can be used to elicit at least a portion of this value. We find that many aspects of the aesthetic environment significantly impact home sale prices. Total view area as well as the areas of some landcover types (water and lawn) in views positively influenced home sale prices while views of impervious surfaces generally negatively influenced home sale price. Access to outdoor recreation areas significantly and positively influenced home sale prices as did tree cover in the neighborhood surrounding a home. These results illustrate the ability of hedonic pricing to identify partial values for ecosystem services and amenities in a manner that is highly relevant to local and regional planning. These values could be used to increase policy-maker and public awareness of ecosystem services and could improve their consideration in planning and policy decisions. (c) 2012 Elsevier Ltd.

SO PLOS ONE LA English DT Article ID WATER MANAGEMENT; CULTIVARS; DISORDER; DIVERSITY; GENOTYPE; MINERALS; MAIZE; LOCUS; QTL AB Straighthead, a physiological disorder characterized by sterile florets and distorted spikelets, causes significant yield losses in rice, and occurs in many countries. The current control method of draining paddies early in the season stresses plants, is costly, and wastes water. Development of resistant cultivar is regarded as the most efficient way for its control. We mapped a QTL for straighthead resistance using two recombinant inbred line (RIL) F-9 populations that were phenotyped over two years using monosodium methanearsonate (MSMA) to induce the symptoms. One population of 170 RILs was genotyped with 136 SSRs and the other population of 91 RILs was genotyped with 159 SSRs. A major QTL qSH-8 was identified in an overlapping region in both populations, and explained 46% of total variation in one and 67% in another population for straighthead resistance. qSH-8 was fine mapped from 1.0 Mbp to 340 kb using 7 SSR markers and further mapped to 290 kb in a population between RM22573 and InDel 27 using 4 InDel markers. SSR AP3858-1 and InDel 11 were within the fine mapped region, and co-segregated with straighthead resistance in both RIL populations, as well as in a collection of diverse global accessions. These results demonstrate that AP3858-1 and InDel 11 can be used for marker-assisted selection (MAS) for straighthead resistant cultivars, which is especially important because there is no effective way to directly evaluate straighthead resistance.

However, both GC-MS and LC-MS are susceptible to matrix effects which can adversely affect quantification depending on the analyte, matrix, sample preparation, instrumentation, and operating conditions. Among the approaches that reduce matrix effects, the most common in pesticide residue applications is matrix-matched calibration because it is relatively inexpensive and simple. Also, it has been shown to work well during method validation when fortified samples are exactly matched with samples used for calibration. However, the quality of matrix-matched results in real-world analyses depends on the consistency of matrix effects among diverse samples. In this study, the variability of matrix effects was measured for 38 representative pesticides in 20 samples each (including different varieties) of rice, orange. apple, and spinach extracted using the "quick, easy, cheap, effective, rugged, and safe" (QuEChERS) method for analysis by LC-MS/MS and low-pressure GC-MS. Using LC-MS/MS, only oranges gave >20% matrix effects for a few pesticides. GC-MS exhibited larger matrix effects, but as in LC-MS/MS, the differences were reasonably consistent among the 20 samples tested. Main conclusions of this study are that for the conditions utilized: (1) matrix-matching was not needed for most pesticides in the simpler food matrices: and (2) for the more complex orange matrix, acceptably accurate quantitative results were achieved by using matrix-matching even with a different sample of the same type. However, full confidence cannot be extended to matrix-matched results, and for consequential applications such as regulatory enforcement, confirmatory analyses using alternate quantitative determinations should also be conducted.

TI Bone mineral density in elite adolescent female figure skaters SO JOURNAL OF THE INTERNATIONAL SOCIETY OF SPORTS NUTRITION LA English DT Article ID BODY-COMPOSITION; ATHLETE TRIAD; YOUNG-WOMEN; ENERGY; OSTEOPOROSIS; DIAGNOSIS; CHILDREN; WEIGHT; SPORTS; MASS AB Elite adolescent figure skaters must accommodate both the physical demands of competitive training and the accelerated rate of bone growth that is associated with adolescence, in this sport that emphasizes leanness. Although, these athletes apparently have sufficient osteogenic stimuli to mitigate the effects of possible low energy availability on bone health, the extent or magnitude of bone accrual also varies with training effects, which differ among skater disciplines. Purpose: We studied differences in total and regional bone mineral density in 36 nationally ranked skaters among 3 skater disciplines: single, pairs, and dancers. Methods: Bone mineral density (BMD) of the total body and its regions was measured by dual energy x-ray absorptiometry (DXA). Values for total body, spine, pelvis and leg were entered into a statistical mixed regression model to identify the effect of skater discipline on bone mineralization while controlling for energy, vitamin D, and calcium intake. Results: The skaters had a mean body mass index of 19.8 +/- 2.1 and % fat mass of 19.2 +/- 5.8. After controlling for dietary intakes of energy, calcium, and vitamin D, there was a significant relationship between skater discipline and BMD (p = 0.002), with single skaters having greater BMD in the total body, legs, and pelvis than ice dancers (p < 0.001). Pair skaters had greater pelvic BMD than ice dancers (p = 0.001). Conclusions: Single and pair skaters have greater BMD than ice dancers. The osteogenic effect of physical training is most apparent in single skaters, particularly in the bone loading sites of the leg and pelvis.

TI Historical and Contemporary DNA Indicate Fisher Decline and Isolation Occurred Prior to the European Settlement of California SO PLOS ONE LA English DT Article ID EFFECTIVE POPULATION-SIZE; ALLELE FREQUENCY DATA; MARTES-PENNANTI; GENETIC DIVERSITY; MICROSATELLITE LOCI; ANCIENT DNA; LANDSCAPE GENETICS; MUSEUM SPECIMENS; RANGE; CONSERVATION AB Establishing if species contractions were the result of natural phenomena or human induced landscape changes is essential for managing natural populations. Fishers (Martes pennanti) in California occur in two geographically and genetically isolated populations in the northwestern mountains and southern Sierra Nevada. Their isolation is hypothesized to have resulted from a decline in abundance and distribution associated with European settlement in the 1800s. However, there is little evidence to establish that fisher occupied the area between the two extant populations at that time. We analyzed 10 microsatelliteloci from 275 contemporary and 21 historical fisher samples (1880-1920) to evaluate the demographic history of fisher in California. We did not find any evidence of a recent (post-European) bottleneck in the northwestern population. In the southern Sierra Nevada, genetic subdivision within the population strongly influenced bottleneck tests. After accounting for genetic subdivision, we found a bottleneck signal only in the northern and central portions of the southern Sierra Nevada, indicating that the southernmost tip of these mountains may have acted as a refugium for fisher during the anthropogenic changes of the late 19th and early 20th centuries. Using a coalescent-based Bayesian analysis, we detected a 90% decline in effective population size and dated the time of decline to over a thousand years ago. We hypothesize that fisher distribution in California contracted to the two current population areas pre-European settlement, and that portions of the southern Sierra Nevada subsequently experienced another more recent bottleneck post-European settlement.

TI Developing a broader scientific foundation for river restoration: Columbia River food webs SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID STEELHEAD ONCORHYNCHUS-MYKISS; JUVENILE SALMONIDS; CHINOOK SALMON; PACIFIC SALMON; MANAGEMENT; ECOSYSTEM; CONSERVATION; POPULATIONS; PREDATION; ABUNDANCE AB Well-functioning food webs are fundamental for sustaining rivers as ecosystems and maintaining associated aquatic and terrestrial communities. The current emphasis on restoring habitat structure-without explicitly considering food webs-has been less successful than hoped in terms of enhancing the status of targeted species and often overlooks important constraints on ecologically effective restoration. We identify three priority food web-related issues that potentially impede successful river restoration: uncertainty about habitat carrying capacity, proliferation of chemicals and contaminants, and emergence of hybrid food webs containing a mixture of native and invasive species. Additionally, there is the need to place these food web considerations in a broad temporal and spatial framework by understanding the consequences of altered nutrient, organic matter (energy), water, and thermal sources and flows, reconnecting critical habitats and their food webs, and restoring for changing environments. As an illustration, we discuss how the Columbia River Basin, site of one of the largest aquatic/riparian restoration programs in the United States, would benefit from implementing a food web perspective. A food web perspective for the Columbia River would complement ongoing approaches and enhance the ability to meet the vision and legal obligations of the US Endangered Species Act, the Northwest Power Act (Fish and Wildlife Program), and federal treaties with Northwest Indian Tribes while meeting fundamental needs for improved river management.

TI Structure and Radical Scavenging Activity Relationships of Pyrolytic Lignins SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE pyrolytic lignin; acetylation; trifluoromethylation; functional groups; free radical scavenging activity ID ANTIOXIDANT ACTIVITY; PLANT-EXTRACTS; BIO-OIL AB This work deals with antioxidant properties of pyrolytic lignins against two free radicals, 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid). Pyrolytic lignins produced by the thermal pyrolysis of the Etek lignin were extracted from the liquid pyrolysis product and fractionated using solvents of different polarities. The main functional groups linked to the lignin skeleton have been characterized by H-1 NMR and F-19 NMR upon acetylation and trifluoromethylation, respectively. Their radical scavenging activity against targeted free radicals was evaluated in vitro, and it was correlated to the content of studied functional groups. In contrast to the extracted Etek lignin, thermal pyrolysis produces lignin adducts that have higher scavenging efficacy than the nonthermally altered lignin and even higher than that of quercetin, a well-known phenolic antioxidant. The phenyl hydroxyl and methoxyl groups appear to be the main lignin structural factors contributing to the overall scavenging properties against the DPPH and ABTS free radicals. Also, these results show that there is no correlation between the content of aliphatic hydroxyl and carbonyl groups and the antioxidant activity.

This could be through food intake, but results are contradictory. Modulation by diet or other lifestyle factors is also not well understood. Objective: To investigate whether MC4R and FTO associations with body-weight are modulated by diet and physical activity (PA), and to study their association with alcohol and food intake. Methods: Adherence to Mediterranean diet (AdMedDiet) and physical activity (PA) were assessed by validated questionnaires in 7,052 high cardiovascular risk subjects. MC4R rs17782313 and FTO rs9939609 were determined. Independent and joint associations (aggregate genetic score) as well as statistical and biological gene-lifestyle interactions were analyzed. Results: FTO rs9939609 was associated with higher bodymass index (BMI), waist circumference (WC) and obesity (P < 0.05 for all). A similar, but not significant trend was found for MC4R rs17782313. Their additive effects (aggregate score) were significant and we observed a 7% per-allele increase of being obese (OR = 1.07; 95% CI 1.01-1.13). We found relevant statistical interactions (P, 0.05) with PA. So, in active individuals, the associations with higher BMI, WC or obesity were not detected. A biological (non-statistical) interaction between AdMedDiet and rs9939609 and the aggregate score was found. Greater AdMedDiet in individuals carrying 4 or 3-risk alleles counterbalanced their genetic predisposition, exhibiting similar BMI (P = 0.502) than individuals with no risk alleles and lower AdMedDiet. They also had lower BMI (P = 0.021) than their counterparts with low AdMedDiet. We did not find any consistent association with energy or macronutrients, but found a novel association between these polymorphisms and lower alcohol consumption in variant-allele carriers (B+/-SE: -0.57+/-0.16 g/d per-score-allele; P = 0.001). Conclusion: Statistical and biological interactions with PA and diet modulate the effects of FTO and MC4R polymorphisms on obesity. The novel association with alcohol consumption seems independent of their effects on BMI.

This is the first Cryptosporidium mouse model in which the relationship between infection and apoptosis has been histologically studied at each portion of the gut in order to observe this dynamic in chronic cryptosporidiosis. Histology showed developmental stages in the duodenum, proximal and distal jejunum, ileum, cecum and colon, with the small intestine remaining infected until day 35 post infection. At proximal jejunum an inverse correlation between infection and apoptosis was observed at days 28 and 35 p.i. Data suggests that jejunum could be an interesting place to carry out further studies on the dynamics of Cryptosporidium infection and apoptosis. Based on these findings, this mouse model was useful to evaluate clinical, parasitological and histological aspects of C. parvum subtype IIaA21G1R1 infection, and it will be an appropriate tool to investigate different aspects of Cryptosporidium infection.

TI A New Class of Wheat Gliadin Genes and Proteins SO PLOS ONE LA English DT Article ID DISULFIDE BONDS; FAMILY-STRUCTURE; GLUTEN PROTEINS; GAMMA-3 HORDEIN; BARLEY; LOCATION; SEQUENCE; BREAD AB The utility of mining DNA sequence data to understand the structure and expression of cereal prolamin genes is demonstrated by the identification of a new class of wheat prolamins. This previously unrecognized wheat prolamin class, given the name delta-gliadins, is the most direct ortholog of barley gamma 3-hordeins. Phylogenetic analysis shows that the orthologous delta-gliadins and gamma 3-hordeins form a distinct prolamin branch that existed separate from the gamma-gliadins and gamma-hordeins in an ancestral Triticeae prior to the branching of wheat and barley. The expressed delta-gliadins are encoded by a single gene in each of the hexaploid wheat genomes. This single delta-gliadin/gamma 3-hordein ortholog may be a general feature of the Triticeae tribe since examination of ESTs from three barley cultivars also confirms a single gamma 3-hordein gene. Analysis of ESTs and cDNAs shows that the genes are expressed in at least five hexaploid wheat cultivars in addition to diploids Triticum monococcum and Aegilops tauschii. The latter two sequences also allow assignment of the delta-gliadin genes to the A and D genomes, respectively, with the third sequence type assumed to be from the B genome. Two wheat cultivars for which there are sufficient ESTs show different patterns of expression, i.e., with cv Chinese Spring expressing the genes from the A and B genomes, while cv Recital has ESTs from the A and D genomes. Genomic sequences of Chinese Spring show that the D genome gene is inactivated by tandem premature stop codons. A fourth delta-gliadin sequence occurs in the D genome of both Chinese Spring and Ae. tauschii, but no ESTs match this sequence and limited genomic sequences indicates a pseudogene containing frame shifts and premature stop codons. Sequencing of BACs covering a 3 Mb region from Ae. tauschii locates the delta-gliadin gene to the complex Gli-1 plus Glu-3 region on chromosome 1.

TI Greenhouse-Selected Resistance to Cry3Bb1-Producing Corn in Three Western Corn Rootworm Populations SO PLOS ONE LA English DT Article ID VIRGIFERA-VIRGIFERA COLEOPTERA; FIELD-EVOLVED RESISTANCE; TO-PLANT MOVEMENT; TRANSGENIC CORN; BACILLUS-THURINGIENSIS; INSECT RESISTANCE; FITNESS COSTS; BT MAIZE; LABORATORY COLONIES; LARVAE COLEOPTERA AB Transgenic corn producing the Bacillus thuringiensis (Bt) toxin Cry3Bb1 has been useful for controlling western corn rootworm, Diabrotica virgifera virgifera LeConte, one of the most economically important crop pests in the United States. However, rapid evolution of resistance by this beetle to Bt corn producing Cry3Bb1 has been reported previously from the laboratory, greenhouse, and field. Here we selected in the greenhouse for resistance to Cry3Bb1 corn in three colonies of WCR derived from Kansas, Minnesota, and Wisconsin, respectively. Three generations of rearing on Cry3Bb1 corn significantly increased larval survival on Cry3Bb1 corn, resulting in similar survival in the greenhouse for selected colonies on Cry3Bb1 corn and isoline corn that does not produce Bt toxin. After four to seven generations of rearing on Cry3Bb1 corn, survival in the field on Cry3Bb1 corn relative to isoline corn more than doubled for selected colonies (72%) compared with control colonies (33%). For both selected and control colonies, survival in the field was significantly lower on Cry3Bb1 corn than on isoline corn. On isoline corn, most fitness components were similar for selected colonies and control colonies. However, fecundity was significantly lower for selected colonies than control colonies, indicating a fitness cost associated with resistance. The rapid evolution of resistance by western corn rootworm to Bt corn reported here and previously underlines the importance of effective resistance management for this pest.

AB High-throughput genome scans are important tools for genetic studies and breeding applications. Here, a 6K SNP array for use with the Illumina Infinium (R) system was developed for diploid sweet cherry (Prunus avium) and allotetraploid sour cherry (P. cerasus). This effort was led by RosBREED, a community initiative to enable marker-assisted breeding for rosaceous crops. Next-generation sequencing in diverse breeding germplasm provided 25 billion basepairs (Gb) of cherry DNA sequence from which were identified genome-wide SNPs for sweet cherry and for the two sour cherry subgenomes derived from sweet cherry (avium subgenome) and P. fruticosa (fruticosa subgenome). Anchoring to the peach genome sequence, recently released by the International Peach Genome Initiative, predicted relative physical locations of the 1.9 million putative SNPs detected, preliminarily filtered to 368,943 SNPs. Further filtering was guided by results of a 144-SNP subset examined with the Illumina GoldenGate (R) assay on 160 accessions. A 6K Infinium (R) II array was designed with SNPs evenly spaced genetically across the sweet and sour cherry genomes. SNPs were developed for each sour cherry subgenome by using minor allele frequency in the sour cherry detection panel to enrich for subgenome-specific SNPs followed by targeting to either subgenome according to alleles observed in sweet cherry. The array was evaluated using panels of sweet (n = 269) and sour (n = 330) cherry breeding germplasm. Approximately one third of array SNPs were informative for each crop. A total of 1825 polymorphic SNPs were verified in sweet cherry, 13% of these originally developed for sour cherry. Allele dosage was resolved for 2058 polymorphic SNPs in sour cherry, one third of these being originally developed for sweet cherry. This publicly available genomics resource represents a significant advance in cherry genome-scanning capability that will accelerate marker-locus-trait association discovery, genome structure investigation, and genetic diversity assessment in this diploid-tetraploid crop group.

Wang, Xiyin Schmutz, Jeremy TI Repeated polyploidization of Gossypium genomes and the evolution of spinnable cotton fibres SO NATURE LA English DT Article ID DNA; SEQUENCE; RECOMBINATION; ARABIDOPSIS; PLANTS; ORGANIZATION; BARBADENSE; PATHWAYS; ANCIENT; PROTEIN AB Polyploidy often confers emergent properties, such as the higher fibre productivity and quality of tetraploid cottons than diploid cottons bred for the same environments(1). Here we show that an abrupt five-to sixfold ploidy increase approximately 60 million years (Myr) ago, and allopolyploidy reuniting divergent Gossypium genomes approximately 1-2 Myr ago(2), conferred about 30-36-fold duplication of ancestral angiosperm (flowering plant) genes in elite cottons (Gossypium hirsutum and Gossypium barbadense), genetic complexity equalled only by Brassica(3) among sequenced angiosperms. Nascent fibre evolution, before allopolyploidy, is elucidated by comparison of spinnable-fibred Gossypium herbaceum A and non-spinnable Gossypium longicalyx F genomes to one another and the outgroup D genome of non-spinnable Gossypium raimondii. The sequence of a G. hirsutum A(t)D(t) (in which 't' indicates tetraploid) cultivar reveals many non-reciprocal DNA exchanges between subgenomes that may have contributed to phenotypic innovation and/or other emergent properties such as ecological adaptation by polyploids. Most DNA-level novelty in G. hirsutum recombines alleles from the D-genome progenitor native to its New World habitat and the Old World A-genome progenitor in which spinnable fibre evolved. Coordinated expression changes in proximal groups of functionally distinct genes, including a nuclear mitochondrial DNA block, may account for clusters of cotton-fibre quantitative trait loci affecting diverse traits. Opportunities abound for dissecting emergent properties of other polyploids, particularly angiosperms, by comparison to diploid progenitors and outgroups.

IRiS is a system that estimates the ARG on sequences of individuals, at genomic scales, capturing the relationship between these individuals of the species. Recently, this system was used to estimate the ARG of the recombining X Chromosome of a collection of human populations using relatively dense, bi-allelic SNP data. Results: While the ARG is a natural model for capturing the inter-relationship between a single chromosome of the individuals of a species, it is not immediately apparent how the model can utilize whole-genome (across chromosomes) diploid data. Also, the sheer complexity of an ARG structure presents a challenge to graph visualization techniques. In this paper we examine the ARG reconstruction for (1) genome-wide or multiple chromosomes, (2) multi-allelic and (3) extremely sparse data. To aid in the visualization of the results of the reconstructed ARG, we additionally construct a much simplified topology, a classification tree, suggested by the ARG. As the test case, we study the problem of extracting the relationship between populations of Theobroma cacao. The chocolate tree is an outcrossing species in the wild, due to self-incompatibility mechanisms at play. Thus a principled approach to understanding the inter-relationships between the different populations must take the shuffling of the genomic segments into account. The polymorphisms in the test data are short tandem repeats (STR) and are multi-allelic (sometimes as high as 30 distinct possible values at a locus). Each is at a genomic location that is bilaterally transmitted, hence the ARG is a natural model for this data. Another characteristic of this plant data set is that while it is genome-wide, across 10 linkage groups or chromosomes, it is very sparse, i.e., only 96 loci from a genome of approximately 400 megabases. The results are visualized both as MDS plots and as classification trees. To evaluate the accuracy of the ARG approach, we compare the results with those available in literature. Conclusions: We have extended the ARG model to incorporate genome-wide (ensemble of multiple chromosomes) data in a natural way. We present a simple scheme to implement this in practice. Finally, this is the first time that a plant population data set is being studied by estimating its underlying ARG. We demonstrate an overall precision of 0.92 and an overall recall of 0.93 of the ARG-based classification, with respect to the gold standard. While we have corroborated the classification of the samples with that in literature, this opens the door to other potential studies that can be made on the ARG.

TaqMan and SYBR Green qPCR are two frequently used methods. However, direct comparison of both methods using the same primers and biological samples is still limited. We compared both assays using seven RNAs from the seeds, leaves, and flowers of tung tree (Vernicia fordii), which produces high-value industrial oil. High-quality RNA were isolated from tung tissues, as indicated by a high rRNA ratio and RNA integrity number. qPCR primers and TaqMan probes were optimized. Under optimized conditions, both qPCR gave high correlation coefficiency and similar amplification efficiency, but TaqMan qPCR generated higher y-intercepts than SYBR Green qPCR, which overestimated the expression levels regardless of the genes and tissues tested. This is validated using well-known Dgat2 and Fadx gene expression in tung tissues. The results demonstrate that both assays are reliable for determining gene expression in tung tissues and that the TaqMan assay is more sensitive but generates lower calculated expression levels than the SYBR Green assay. This study suggests that any discussion of gene expression levels needs to be linked to which qPCR method is used in the analysis.

TI Increased lipolysis and altered lipid homeostasis protect gamma-synuclein-null mutant mice from diet-induced obesity SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID ADIPOSE TRIGLYCERIDE LIPASE; ALPHA-SYNUCLEIN; IN-VITRO; GENE; OVEREXPRESSION; RESISTANCE; MUTATIONS; DOPAMINE; DROPLETS; BEHAVIOR AB Synucleins are a family of homologous proteins principally known for their involvement in neurodegeneration. gamma-Synuclein is highly expressed in human white adipose tissue and increased in obesity. Here we show that gamma-synuclein is nutritionally regulated in white adipose tissue whereas its loss partially protects mice from high-fat diet (HFD)-induced obesity and ameliorates some of the associated metabolic complications. Compared with HFD-fed WT mice, HFD-fed gamma-synuclein-null mutant mice display increased lipolysis, lipid oxidation, and energy expenditure, and reduced adipocyte hypertrophy. Knockdown of gamma-synuclein in adipocytes causes redistribution of the key lipolytic enzyme ATGL to lipid droplets and increases lipolysis. gamma-Synuclein-deficient adipocytes also contain fewer SNARE complexes of a type involved in lipid droplet fusion. We hypothesize that gamma-synuclein may deliver SNAP-23 to the SNARE complexes under lipogenic conditions. Via these independent but complementary roles, gamma-synuclein may coordinately modulate lipid storage by influencing lipolysis and lipid droplet formation. Our data reveal gamma-synuclein as a regulator of lipid handling in adipocytes, the function of which is particularly important in conditions of nutrient excess.

TI Sex-specific mating pheromones in the nematode Panagrellus redivivus SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE chemical ecology; chemical signaling; peroxisomal beta-oxidation; metabolomics ID SMALL-MOLECULE SIGNALS; CAENORHABDITIS-ELEGANS; DAUER PHEROMONE; C-ELEGANS; ATTRACTION; COMPONENT; BEHAVIOR AB Nematodes use an extensive chemical language based on glycosides of the dideoxysugar ascarylose for developmental regulation (dauer formation), male sex attraction, aggregation, and dispersal. However, no examples of a female-or hermaphrodite-specific sex attractant have been identified to date. In this study, we investigated the pheromone system of the gonochoristic sour paste nematode Panagrellus redivivus, which produces sex-specific attractants of the opposite sex. Activity-guided fractionation of the P. redivivus exometabolome revealed that males are strongly attracted to ascr#1 (also known as daumone), an ascaroside previously identified from Caenorhabditis elegans hermaphrodites. Female P. redivivus are repelled by high concentrations of ascr#1 but are specifically attracted to a previously unknown ascaroside that we named dhas#18, a dihydroxy derivative of the known ascr#18 and an ascaroside that features extensive functionalization of the lipid-derived side chain. Targeted profiling of the P. redivivus exometabolome revealed several additional ascarosides that did not induce strong chemotaxis. We show that P. redivivus females, but not males, produce the male-attracting ascr#1, whereas males, but not females, produce the female-attracting dhas#18. These results show that ascaroside biosynthesis in P. redivivus is highly sex-specific. Furthermore, the extensive side chain functionalization in dhas#18, which is reminiscent of polyketide-derived natural products, indicates unanticipated biosynthetic capabilities in nematodes.

TI Novel and Distinct Metabolites Identified Following a Single Oral Dose of alpha- or gamma-Hexabromocyclododecane in Mice SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID BROMINATED FLAME RETARDANTS; HYDROXYLATED METABOLITES; TISSUE DISTRIBUTION; REPEATED EXPOSURE; DIPHENYL ETHERS; RAINBOW-TROUT; FOOD-WEB; HBCD; RAT; TOXICOKINETICS AB The metabolism of alpha- and gamma-hexabromocyclododecane (HBCD) was investigated in adult C57BL/6 female mice. alpha- or gamma-[C-14]HBCD (3 mg/kg bw) was orally administered with subsequent urine and feces collection for 4 consecutive days; a separate group of mice was dosed and sacrificed 3 h postexposure to investigate tissue metabolite levels. Extractable and nonextractable HBCD metabolites were quantitated in liver, blood, fat, brain, bile, urine, and feces and characterized by LC/MS (ESI-). Metabolites identified were distinct between the two stereoisomers. In mice exposed to alpha-HBCD, four hydroxylated metabolites were detected in fecal extracts, and one of these metabolite isomers was consistently characterized in liver, brain, and adipose tissue extracts. In contrast, fecal extracts from mice exposed to gamma-HBCD contained multiple isomers of monohydroxy-pentabromocyclododecene, dihydroxy-pentabromocyclododecene, and dihydroxy-pentabromocyclododecadiene, while in liver and adipose tissues extracts only a single monohydroxy-pentabromocyclododecane metabolite was observed. Both stereoisomers were transformed to metabolites which formed covalent bonds to proteins and/or lipids in the gut as suggested by high fecal nonextractables. The presence of tissue- and excreta-specific metabolic products after in vivo exposure to the two main HBCD stereoisomers supports previous toxicokinetic studies indicating that these two stereoisomers are biologically distinct. The distinct metabolic products identified in this study have the potential to aid in the identification of stereoisomer-specific HBCD exposures in future biomonitoring studies.

The present study was conducted to identify MAP proteins that might be candidates for the development of an improved vaccine. MAP proteins were screened for immunogenicity in naturally infected cattle and selected based upon reactivity in the interferon-gamma (IFN-gamma) and Western blot assays. Proteins (MAP1087, MAP1204, MAP1272c, and MAP2077c) were arrayed into 4 overlapping cocktails containing 3 proteins each. The efficacy of the proteins within these cocktails as vaccine candidates was evaluated by subcutaneous immunization of mice, followed by challenge with live, virulent MAP. All MAP protein cocktails significantly reduced the recovery of live MAP from the ileum, while cocktails 1 and 3 reduced colonization in the liver. No significant differences were seen in the mesenteric lymph node or spleen, however, cocktail 1 reduced viable MAP in the mesenteric lymph node compared to other treatments. Stimulation of splenocytes upregulated antigen-specific IFN-gamma and IL-23 secretion in all treatment groups, regardless of vaccination. Interestingly. IL-4 was moderately downregulated for vaccinates compared to control infected mice. An increase in total CD25 expression was noted for 3 of the 4 vaccinate groups upon stimulation of splenocytes with a whole cell sonicate of MAP, with this effect becoming more significant within CD4CD25+ and CD8CD25+ subpopulations. The present study demonstrated that MAP proteins are useful as vaccine candidates to reduce MAP tissue burden. Published by Elsevier Ltd. C1 [Stabel, J. R.; Barnhill, A.; Bannantine, J.

Spatially distributed evaporative fraction (EF) measurements were made monthly from October 2008 to September 2009 at 54 locations across an elevational gradient using a mobile measurement platform, called the Regional Evaporative Fraction Energy Balance (REFEB) method. We used these measurements and the Enhanced Vegetation Index (EVI) from MODerate resolution Imaging Spectroradiometer (MODIS) observations to derive EF at a regional scale. We converted EF to monthly ET using remote-sensing based observations of available energy. We compared the REFEB ET estimates, along with modified Priestly-Taylor (PT) ET estimates driven by MODIS data against four eddy covariance (EC) towers and eight gauged catchments. Both of the satellite-based ET estimates were highly correlated with tower ET observations (r(2) = 0.66 for REFEB and 0.95 for PT). The PT MODIS approach overestimated ET compared to precipitation estimates and stream gauge measurements, while REFEB ET was moderately lower than PT ET. The annual regional REFEB ET (193 mm) was 87 mm less than precipitation (280 mm). REFEB Er underestimated EC tower ET (regression slope = 0.78, p < 0.001). Regional PT ET (288 mm) exceeded precipitation by 8 mm and significantly overestimated EC tower Er (regression slope = 1.43, p < 0.001). The relationship between precipitation and ET is not linear, with a break around 290 mm/year, at which point ET becomes nearly constant at 200-300 mm/year with increasing precipitation. This causes a break in the precipitation-runoff relationship, with a disproportionate increase in runoff when precipitation exceeds 290 mm/year. REFEB provides a viable method to estimate regional ET, which is applicable to areas that are poorly constrained by other remote sensing approaches. Published by Elsevier B.V.

Latent (lambda E) and sensible heat (H) fluxes were linear functions of available energy, and seasonality had a major effect on the partitioning of available energy into lambda E and H at each stand. Both defoliation and prescribed fire reduced leaf area, altered the partitioning of available energy, and reduced lambda E flux compared to undisturbed periods. Summer daily Et averaged 4.2 +/- 1.5, 33 +/- 1.2 and 3.9 +/- 1.3 mm day(-1) at the oak-, mixed, and pine-dominated stands during undisturbed periods, but only 2.4 +/- 0.9 mm day(-1) during defoliation at the oak stand in 2007, and 2.4 +/- 0.9 and 3.2 +/- 0.9 mm day(-1) following spring fires at the mixed and pine-dominated stands, respectively. For all years measured, seasonal maximum leaf area index (LAI) explained 82% of the variability in daily Et during the summer at the oak stand, and 80% of the variability at the mixed and pine-dominated stands. Annual Et averaged 614, 493, and 683 mm yr(-1) at the oak, mixed, and pine stands, respectively. When averaged across all stands and years, annual Et was 606 mm yr(-1), ca. 53.6% of incident precipitation, and similar to long-term averages reported in other studies in the Pinelands. Gypsy moth defoliation potentially reduced Et by ca. 31 mm yr(-1) across all upland forests in 2007, resulting in a 7.3% increase in groundwater recharge. Our research indicates that non-stand replacing disturbances can have significant effects on energy partitioning, and can reduce Et at the stand and landscape scales. Published by Elsevier B.V.

We compared cropland and forest surface temperatures across the continental United States in 16 cells that were approximately 1 degrees x 2 degrees using 1 km(2) MODIS land surface temperature (LST) data and land cover from the 0.0009 km(2) National Land Cover Database (NLCD). We found that forest surface temperatures tended to be cooler than cropland surface temperatures. This relationship held for spring, summer, fall, and annually. In winter, cropland surface temperatures were cooler than forest surface temperatures except in the southeastern United States, where forest surface temperatures were also cooler in winter. The difference between cropland and forest surface temperatures was driven by daytime maxima, which tended to be twice as large as differences in nighttime minima. The dominance of daytime maxima was influenced by the degree of continentality. For cells on coastal margins or with a high proportion of inland lakes, differences between cropland and forest nighttime minima tended to be very small. In more continental locations croplands were noticeably cooler at night which often led to insignificant differences between cropland and forest average surface temperatures.

TI Carbon, water, and heat flux responses to experimental burning and drought in a tallgrass prairie SO AGRICULTURAL AND FOREST METEOROLOGY LA English DT Article DE Grassland; Prairie; Fire; Eddy covariance; Carbon exchange; Water stress ID SOIL CO2 FLUX; GRASSLAND ECOSYSTEM; DIOXIDE FLUXES; EXCHANGE; FIRE; VARIABILITY; FREQUENCY; NORTHERN; VAPOR AB Drought and fire are common disturbances to grassland ecosystems. We report two years of eddy covariance ecosystem-atmosphere fluxes and biometric variables measured in nearby burned and unburned pastures in the US Southern Great Plains. Over the course of the experiment, annual precipitation (similar to 600 mm yr(-1)) was lower than the long term mean (similar to 860 mm yr(-1)). Soil moisture decreased from productive conditions in March 2005 dry, unproductive conditions during the growing season starting in March 2006. Just prior to the burn in early March 2005, burned and unburned pastures contained 520 +/- 60 and 360 +/- 40 g C m(-2) of total above ground biomass (AGB) and litter, respectively. The fire removed approximately 200 g C m(-2) of litter and biomass. In the 2005 growing season following the burn, maximum green AGB was 450 +/- 60 and 270 +/- 40 g C m(-2), with corresponding cumulative annual net ecosystem carbon exchange (NEE) of -330 and -150 g C m(-2) for the burned and unburned pastures, respectively. In contrast to NEE, cumulative mean sensible heat and water fluxes were approximately equal in both pastures during the growing season, suggesting either an increase in water use efficiency or a decrease in evaporation in the burned relative to the unburned pasture. In the 2006 growing season, dry conditions decreased carbon uptake and latent heat, and increased sensible heat fluxes. Peak AGB was reduced to 210 +/- 30 g C m(-2) and 140 +/- 30 g C m(-2) in the burned and unburned pastures, respectively, while NEE was near zero.

TI Mortality and repellent effects of microbial pathogens on Coptotermes formosanus (Isoptera: Rhinotermitidae) SO BMC MICROBIOLOGY LA English DT Article ID METARHIZIUM-ANISOPLIAE; BIOLOGICAL-CONTROL; RETICULITERMES-FLAVIPES; SUBTERRANEAN TERMITES; FUMOSOROSEUS; DEFENSE; SHIRAKI; FUNGI AB Background: Two entomopathogenic fungi, Isaria fumosorosea and Metarhizium anisopliae, and one bacterium, Bacillus thuringiensis, were tested for their ability to cause mortality of Formosan subterranean termites (FST), Coptotermes formosanus (Shiraki), after liquid exposure, and for their lack of propensity to repel FST. Results: The fungus Isaria fumosorosea at 10(8) spores/ml caused 72.5% mortality on day 7, significantly higher than the control and 10(6) spores/ml treatment. On day 14, the 10(6) and 10(8) concentrations caused 38.8% and 92.5% mortality, respectively, significantly higher than the control. On day 21, 82.5% and 100% of the termites were killed by the 10(6) and 10(8) treatments, respectively. I. fumosorosea did not repel termites at 10(6) nor 10(8) spores/g in sand, soil or sawdust. The fungus Metarhizium anisopliae at 10(8) spores/ml caused 57.5% mortality on day 7, 77.5% mortality on day 14 and 100% mortality on day 21. Conclusions: On all three days the rate of mortality was significantly higher than that of the control and 10(6) spores/ml treatment with I. fumosorosea. Neither I. fumosorosea nor M. anisopliae caused repellency of FST in sand, soil or sawdust. The bacterium Bacillus thuringiensis did not cause significant mortality on days 7, 14 or 21. When termites were exposed to cells of B. thuringiensis in sawdust and when termites were exposed to a mixture of spores and cells in sand, a significantly higher number remained in the control tubes. Repellency was not seen with B. thuringiensis spores alone, nor with the above treatments in the other substrates. C1 [Wright, Maureen S.] USDA, So Reg Res Ctr, New Orleans, LA 70179 USA.

TI White ash (Fraxinus americana) decline and mortality: The role of site nutrition and stress history SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Dieback; Health; Magnesium; Calcium; Defoliation ID NORTHEASTERN UNITED-STATES; SUGAR MAPLE HEALTH; ALLEGHENY PLATEAU; FOREST ECOSYSTEMS; TEMPERATE FORESTS; SOIL INTERACTIONS; CROWN CONDITION; CANOPY TREE; DIEBACK; GROWTH AB Over the past century, white ash (Fraxinus americana) populations throughout its range have deteriorated as a result of declining tree health and increased mortality rates. Although co-occurring factors including site nutritional deficiencies and punctuated stress events (e.g., defoliations, drought) are hypothesized to trigger white ash decline, there are no empirical assessments of these factors at regional scales. In this study, we evaluated ash crown dieback, crown health condition, and mortality on 190 plots paired along a topographic gradient known to differ in site nutrition across a 3000 km(2) area of northwestern Pennsylvania, USA. Additionally, we assessed white ash foliar nutrient content and additional factors including defoliation history as potential explanatory variables at all sites. White ash populations on upper slopes consistently had significantly greater dieback, poorer crown condition, and greater mortality than populations in paired plots on lower slopes. Despite nearly two decades since the last major elm spanworm defoliation, this stressor further amplified the differences in health and mortality seen between slope positions. On the relatively cation deficient upper slope positions, crown dieback and crown condition improved with increasing foliar cation (Ca2+, Mg2+) concentration. Our results indicate that white ash health is strongly influenced by site nutrition, and defoliation can trigger declines in cation-deficient sites. Knowledge of how landscape position and nutrition influence white ash health may alter management responses to insect outbreak events. Published by Elsevier B.V.

TI Multiple diseases impact survival of pine species planted in red pine stands harvested in spatially variable retention patterns SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Pine management; Ecological forestry; Sirococcus; Diplodia; Cronartium quercuum f. sp banksianae; Armillaria ID SPHAEROPSIS-SAPINEA; DIPLODIA-PINEA; CRONARTIUM-QUERCUUM; SHOOT BLIGHT; JACK PINES; MINNESOTA; SEEDLINGS; INOCULUM; PLANTATIONS; PERSISTENCE AB Increasing the diversity of species and structure of red pine (Pious resinosa) is often a management goal in stands simplified by practices such as fire suppression and plantation management in many areas of the Great Lakes Region. One approach to diversification is to convert predominantly even-aged, pure red pine stands to multi-cohort, mixed-species forests through variable overstory retention at harvest. Based on limited empirical evidence, pathologists have advised against this multi-cohort approach in stands where pathogens causing damaging shoot blight diseases are established. We examined disease incidence among planted red, jack (Pious banksiana), and white pine (Pious strobus) in a variable retention harvest and understory woody vegetation removal (brushing) experiment in northern Minnesota. The experiment included four overstory treatments (dispersed and two aggregated overstory retention treatments and a control, N = 4) that were split by an understory brushing treatment (yes or no). Prior to harvest in 2003, the fungal pine pathogens Diplodia pinea, Sirococcus conigenus and Armillaria solidipes (syn. Armillaria ostoyae) were common on the study site. Within 6 years after harvest, these pathogens reduced the survival of planted red, white and jack pine, potentially interfering with long-term management objectives. Across all treatments, shoot blight incidence was generally higher in dead red and jack pine than white pine seedlings and was predominantly caused by D. pinea. The disease killing white pine seedlings was predominately Armillaria root rot. Overstory treatment affected the percentage of jack and white pine seedling mortality attributable to shoot blight, but not the more susceptible red pine, with greater overstory retention resulting in greater disease incidence. Understory brushing had no effect on the incidence of shoot blight on seedlings. We expect disease to continue to influence stand structure and composition across all treatments. Our study results highlight the need for forest managers to assess long-term risk of potentially damaging pathogens in red pine stands prior to harvest and use that information to guide decisions regarding silvicultural practices to increase age and species diversity.

Evidence of historic burning has prompted the use of prescribed fire as a tool to improve the competitive status of oak regeneration in mature stands. A primary shortfall of fire effects research in oak forests has been a lack of long-term studies on the effects of multiple fires. Here we describe the effects of repeated fires on stand structure and tree regeneration over a 13-year period in mature mixed-oak forests located in southern Ohio, USA. Three stands were burned 3-5 times from 1996 to 2005 with low-intensity dormant-season fires, and two stands remained unburned. Woody vegetation was sampled periodically on nine 0.125 ha plots per stand. Plots were located across the upland landscape and were characterized by an Integrated Moisture Index. Fire altered stand structure by reducing the density of large saplings (3.0-9.9 cm DBH) and midstory trees (10-25 cm DBH) by 76% and 34%, respectively. Fire had little impact on trees >25 cm DBH. Small saplings (1.4 m tall to 2.9 cm DBH) were dynamic over time on dry plots that were burned. After being repeatedly topkilled from year 1-8, the small sapling layer had redeveloped on dry burned plots by year 13 and species composition had shifted from dominance by shade-tolerant species to a more equal distribution of shade-tolerants, oaks + hickories, and sassafras. The density of oak + hickory and sassafras advance regeneration (stems 30 cm tall to 2.9 cm DBH) was significantly greater on burned plots than on unburned plots in year 13, though variability among plots was high. Advance regeneration of shade-tolerant species was equally abundant on burned and unburned plots. Density of oak + hickory advance regeneration in year 13 was positively related to its weighted frequency (a surrogate for size and abundance) in year 0 (r(2) = 0.67, p < 0.0001) and inversely related to stand density (r(2) = 0.33, p < 0.0001) and canopy cover (r(2) = 0.31, p < 0.0001), both of which were reduced by fire. Although oak + hickory advance regeneration was more abundant on burned plots, we conclude that other methods (e.g., herbicide, partial cutting) are necessary to further reduce stand density and promote the development of larger oak + hickory regeneration, particularly on mesic sites.

Screening trial experiments, including potassium (K), sulfur (S), and boron (B) multiple nutrient treatments, have been conducted to learn about Douglas-fir nutritional status and fertilizer growth response. The data from the screening trial experiments were compiled to test whether the soil parent materials of the region could be used to predict nutritional status. Estimating effects of fertilizers and soil parent materials on Douglas-fir growth from compilations of such experiments, however, poses challenges and opportunity; experiments clustered in time and space introduce latent variables that drive between-site variation. We used a two-stage modeling approach to efficiently take advantage of the information in these data. First, we employed a mixed model approach to test the primary hypothesis of soil parent material influence upon stem growth response to fertilizer. As the second-stage to the analysis, the predicted random effects estimated from the mixed model were used as a response variable to test how strongly precipitation drives between-site variation. As expected, including the random site effect significantly improved the model fit of the growth model (Lambda = 436.5, P < 0.0001). The full mixed model accounted for 85% of the variation in the growth data (R-2 = 0.85) and revealed an interaction between fertilizer treatment and soil parent material class (P = 0.0179). Post hoc analysis suggested that Douglas-fir growing on loessal soils are not constrained by K, S, or B, but no general consistency was apparent with tephra or underlying geology. The second stage modeling suggested that winter precipitation explains variation in predicted random site effects (r(2) = 0.23), and hence the growth difference, better than total precipitation. Also, the annual lag precipitation explains variation in predicted random effects comparably well (r(2) = 0.22). (C) 2012 Elsevier B.V. All rights reserved.

This degradation was masked by spectrophotometric analysis but clearly evident by microfluidic-based assay. Although not specifically identified, the degrading entity was endogenous and localized to the abdomen (terminal abdominal segments) of adult ants. RNA degradation was not observed in preparations of larvae, non-melanized pupae, or eggs. Various RNase and protease inhibitors had no protective effect. However, the metal chelating agent ethylenediaminetetraacetic acid prevented RNA degradation and provides insight into the occurrence.

It was prepared in a three-step procedure consisting of (i) transesterification reaction between ethylene glycol and a high-molecular-weight PHB, (ii) synthesis of bromo-terminated PHB macroinitiator, and (iii) atom transfer radical polymerization polymerization of styrene initiated by the PHB-based macroinitiator. Fourier transform infrared, gel permeation chromatography, 1H-, and 13C-NMR spectroscopies were used to determine the molecular structure and/or end-group functionalities at each step of the procedure. Although thermogravimetric analysis showed that the block copolymer underwent a stepwise thermal degradation and had better thermal stability than their respective homopolymers, differential scanning calorimetry displayed that the PHB block in the copolymer could not crystallize, and thus generating a total amorphous structure. Atomic force microscopy images indicated that the block copolymer was phase segregated in a well-defined morphological structure with nanodomain size of 40 nm. Contact angle measurements proved that the wettability properties of the block copolymer were in between those of the PHB and PS homopolymers. Blends analyzed for their morphology and thermal properties showed good miscibility and had well-defined morphological features. Polymer blends exhibited lower crystallinity and decreased stiffness which was proportional to the amount of compatibilizer content in the blends. (C) 2012 Wiley Periodicals, Inc.

The VIVA LA FAMILIA Study was designed to genetically map childhood obesity and associated biological processes in the Hispanic population. A genome-wide association study (GWAS) entailed genotyping 1.1 million single nucleotide polymorphisms (SNPs) using the Illumina Infinium technology in 815 children. Measured genotype analysis was performed between genetic markers and obesity-related traits i.e., anthropometry, body composition, growth, metabolites, hormones, inflammation, diet, energy expenditure, substrate utilization and physical activity. Identified genome-wide significant loci: 1) corroborated genes implicated in other studies (MTNR1B, ZNF259/APOA5, XPA/FOXE1 (TTF-2), DARC, CCR3, ABO); 2) localized novel genes in plausible biological pathways (PCSK2, ARHGAP11A, CHRNA3); and 3) revealed novel genes with unknown function in obesity pathogenesis (MATK, COL4A1). Salient findings include a nonsynonymous SNP (rs1056513) in INADL (p = 1.2E-07) for weight; an intronic variant in MTNR1B associated with fasting glucose (p = 3.7E-08); variants in the APOA5-ZNF259 region associated with triglycerides (p = 2.5-4.8E-08); an intronic variant in PCSK2 associated with total antioxidants (p = 7.6E-08); a block of 23 SNPs in XPA/FOXE1 (TTF-2) associated with serum TSH (p = 5.5E-08 to 1.0E-09); a nonsynonymous SNP (p = 1.3E-21), an intronic SNP (p = 3.6E-13) in DARC identified for MCP-1; an intronic variant in ARHGAP11A associated with sleep duration (p = 5.0E-08); and, after adjusting for body weight, variants in MATK for total energy expenditure (p = 2.7E-08) and in CHRNA3 for sleeping energy expenditure (p = 6.0E-08). Unprecedented phenotyping and high-density SNP genotyping enabled localization of novel genetic loci associated with the pathophysiology of childhood obesity.

TI A Conjugative 38 kB Plasmid Is Present in Multiple Subspecies of Xylella fastidiosa SO PLOS ONE LA English DT Article ID LEAF SCORCH DISEASE; PIERCES-DISEASE; GENOME SEQUENCES; IV SECRETION; STRAINS; RECOMBINATION; DIVERSITY; BACTERIUM; CALIFORNIA; SYSTEMS AB A similar to 38kB plasmid (pXF-RIV5) was present in the Riv5 strain of Xylella fastidiosa subsp. multiplex isolated from ornamental plum in southern California. The complete nucleotide sequence of pXF-RIV5 is almost identical to that of pXFAS01 from X. fastidiosa subsp. fastidiosa strain M23; the two plasmids vary at only 6 nucleotide positions. BLAST searches and phylogenetic analyses indicate pXF-RIV5 and pXFAS01 share some similarity to chromosomal and plasmid (pXF51) sequences of X. fastidiosa subsp. pauca strain 9a5c and more distant similarity to plasmids from a wide variety of bacteria. Both pXF-RIV5 and pXFAS01 encode homologues of a complete Type IV secretion system involved in conjugation and DNA transfer among bacteria. Mating pair formation proteins (Trb) from Yersinia pseudotuberculosis IP31758 are the mostly closely related non-X. fastidiosa proteins to most of the Trb proteins encoded by pXF-RIV5 and pXFAS01. Unlike many bacterial conjugative plasmids, pXF-RIV5 and pXFAS01 do not carry homologues of known accessory modules that confer selective advantage on host bacteria. However, both plasmids encode seven hypothetical proteins of unknown function and possess a small transposon-associated region encoding a putative transposase and associated factor. Vegetative replication of pXF-RIV5 and pXFAS01 appears to be under control of RepA protein and both plasmids have an origin of DNA replication (oriV) similar to that of pRP4 and pR751 from Escherichia coli. In contrast, conjugative plasmids commonly encode TrfA and have an oriV similar to those found in IncP-1 incompatibility group plasmids. The presence of nearly identical plasmids in single strains from two distinct subspecies of X. fastidiosa is indicative of recent horizontal transfer, probably subsequent to the introduction of subspecies fastidiosa to the United States in the late 19th century.

The purpose of this study was to examine the association of 100% OJ consumption with nutrient adequacy, diet quality, and risk factors for metabolic syndrome (MetS) in a nationally representative sample of adults. Methods: Data from adults 19+ years of age (n = 8,861) participating in the National Health and Nutrition Examination Survey 2003-2006 were used. The National Cancer Institute method was used to estimate the usual intake (UI) of 100% OJ consumption, selected nutrients, and food groups. Percentages of the population below the Estimated Average Requirement (EAR) or above the Adequate Intake (AI) were determined. Diet quality was measured by the Healthy Eating Index-2005 (HEI-2005). Covariate adjusted logistic regression was used to determine if consumers had a lower odds ratio of being overweight or obese or having risk factors of MetS or MetS. Results: Usual per capita intake of 100% OJ was 50.3 ml/d. Among consumers (n = 2,310; 23.8%), UI was 210.0 ml/d. Compared to non-consumers, consumers had a higher (p < 0.05) percentage (% +/- SE) of the population meeting the EAR for vitamin A (39.7 +/- 2.5 vs 54.0 +/- 1.2), vitamin C (0.0 +/- 0.0 vs 59.0 +/- 1.4), folate (5.8 +/- 0.7 vs 15.1 +/- 0.9), and magnesium (51.6 +/- 1.6 vs 63.7 +/- 1.2). Consumers were also more likely to be above the AI for potassium (4.1 +/- 0.8 vs 1.8 +/- 0.2). HEI-2005 was significantly (p < 0.05) higher in consumers (55.0 +/- 0.4 vs 49.7 +/- 0.3). Consumers also had higher intakes of total fruit, fruit juice, whole fruit, and whole grain. Consumers had a lower (p < 0.05) mean body mass index (27.6 +/- 0.2 vs 28.5 +/- 0.1), total cholesterol levels (197.6 +/- 1.2 vs 200.8 +/- 0.75 mg/dL), and low density lipoprotein-cholesterol levels (112.5 +/- 1.4 vs 116.7 +/- 0.93 mg/dL). Finally, compared to non-consumers of 100% OJ, consumers were 21% less likely to be obese and male consumers were 36% less likely to have MetS. Conclusion: The results suggest that moderate consumption of 100% OJ should be encouraged to help individuals meet the USDA daily recommendation for fruit intake and as a component of a healthy diet.

HP slightly inhibited Salmonella Typhimurium bacteria in culture and stimulated uptake of the bacteria into RAW 264.7 murine macrophage cells as indicated by both increased fluorescence from internalized FITC-dextran and increased colony-forming unit (CFU) counts of the lysed macrophages. Postinfection, the HP-treated cells showed lower bacterial counts than the control. HP elicited altered morphology, elevated inducible NO synthase (iNOS) mRNA, and reduced pro-inflammatory cytokine expression in macrophage cells. Salmonella induced increased expression of iNOS mRNA, cognate polypeptides, and NO. Histology of mice infected with a sublethal dose (1 x 10(4) CPU) of Salmonella showed that intraperitoneally administered HP protected against necrosis of the liver, a biomarker of in vivo salmonellosis. The lifespan of mice infected with a lethal dose (1 X 10(5) CFU) was significantly extended. These results suggest that the activity of HP against bacterial infection in mice occurs through the activation of innate immune macrophage cells. The relationship of composition of HP to bioactivity is discussed. C1 [Moon, Eunpyo; Nam, Seok Hyun] Ajou Univ, Dept Biol Sci, Suwon 443749, South Korea.

Cattle and small ruminants are important animal reservoirs of STEC. The present study investigated animal reservoirs for STEC in small rural farms in the Culiacan Valley, an important agricultural region located in Northwest Mexico. A total of 240 fecal samples from domestic animals were collected from five sampling sites in the Culiacan Valley and were subjected to an enrichment protocol followed by either direct plating or immunomagnetic separation before plating on selective media. Serotype O157:H7 isolates with the virulence genes stx2, eae, and ehxA were identified in 40% (26/65) of the recovered isolates from cattle, sheep and chicken feces. Pulse-field gel electrophoresis (PFGE) analysis grouped most O157: H7 isolates into two clusters with 98.6% homology. The use of multiple-locus variable-number tandem repeat analysis (MLVA) differentiated isolates that were indistinguishable by PFGE. Analysis of the allelic diversity of MLVA loci suggested that the O157: H7 isolates from this region were highly related. In contrast to O157: H7 isolates, a greater genotypic diversity was observed in the non-O157 isolates, resulting in 23 PFGE types and 14 MLVA types. The relevant non-O157 serotypes O8:H19, O75:H8, O111:H8 and O146:H21 represented 35.4% (23/65) of the recovered isolates. In particular, 18.5% (12/65) of all the isolates were serotype O75: H8, which was the most variable serotype by both PFGE and MLVA. The non-O157 isolates were predominantly recovered from sheep and were identified to harbor either one or two stx genes. Most non-O157 isolates were ehxA-positive (86.5%, 32/37) but only 10.8% (4/37) harbored eae. These findings indicate that zoonotic STEC with genotypes associated with human illness are present in animals on small farms within rural communities in the Culiacan Valley and emphasize the need for the development of control measures to decrease risks associated with zoonotic STEC.

Subjects and Methods: VAT and SAT biopsies were obtained from morbid obese women (body mass index >= 40 kg/m(2)) (n = 6). In order to investigate rhythmic expression pattern of clock genes and the effect of DEX on CLOCK, PER2 and BMAL1 expression, control AT (without DEX) and AT explants treated with DEX (2 hours) were cultured during 24 h and gene expression was analyzed at the following times: 10:00 h, 14:00 h, 18:00 h, 22:00 h, 02:00 h and 06:00 h, using qRT-PCR. Results: CLOCK, BMAL1 and PER2 expression exhibited circadian patterns in both VAT and SAT explants that were adjusted to a typical 24 h sinusoidal curve. PER2 expression (negative element) was in antiphase with respect to CLOCK and in phase with BMAL1 expression (both positive elements) in the SAT (situation not present in VAT). A marked effect of DEX exposure on both positive and negative clock genes expression patterns was observed. Indeed, DEX treatment modified the rhythmicity pattern towards altered patterns with a period lower than 24 hours in all genes and in both tissues. Conclusions: 24 h patterns in CLOCK and BMAL1 (positive clock elements) and PER2 (negative element) mRNA levels were observed in human adipose explants. These patterns were altered by dexamethasone exposure. C1 [Gomez-Abellan, Purificacion; Madrid, Juan A.; Garaulet, Marta] Univ Murcia, Dept Physiol, Fac Biol, Murcia, Spain.

Central to this determination is the identification of characters that allow assessment of physiological age. While non-destructive measures produce the most desired outcomes, internal markers may be more diagnostic and reliable. In this study, key morphological characters during previtellogenesis through vitellogenesis and ovulation were assessed as markers to determine physiological states of the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae). Ovary length and width, ovarian index (length x width), and egg load of laboratory-reared B. dorsalis females recorded daily from eclosion up to 80 days old suggested significant differences in the ovarian index and egg load between females from each oogenesis stage. Parity status determined by the presence of follicular relics was found to provide high-accuracy classifications for B. dorsalis females. The presence of follicular relics with distinct morphological features provides a reliable identification tool to determine the physiological state of wild female oriental fruit fly. The potential applications of this technique to identify the physiological age of female fruit flies to study behavioral attributes in their natural habitat, and also the potential applications in relation to field control, are discussed.

To evaluate the role of quail as an intermediate host of IAVs, co-infections of quail with swine-origin pandemic H1N1 2009 (pH1N1) and low pathogenic avian influenza (LPAI) duck H3N2 (dkH3N2) viruses (n = 10) or endemic Thai swine H1N1 (swH1N1) and dkH3N2 viruses (n = 10) were conducted. Three additional groups of five quail were each inoculated with pH1N1, swH1N1 and dkH3N2 as control groups to verify that each virus can infect quail. Our result showed that co-infected quail shed higher viral titers from the respiratory tract than single virus infected quail. This study confirmed that reassortant viruses could be readily generated in the respiratory tract of quail from both the pH1N1/dkH3N2 co-infected group (100% of quail generating reassortant viruses) and the swH1N1/dkH3N2 (33% of quail generating reassortant viruses) co-infected group without discernible clinical signs. The reassortment efficacy between the two combination of viruses was different in that the frequency of reassortant viruses was significantly higher in pH1N1/dkH3N2 co-infected quail (21.4%) compared to swH1N1/dkH3N2 co-infected quail (0.8%), indicating that gene combinations in pH1N1 have a higher potential to reassort with dkH3N2 compared to swH1N1. In summary, our result confirmed that quail could be an intermediate host of IAVs for generating new reassortant viruses. Our finding highlights the importance of monitoring IAVs especially pH1N1 in quail. (C) 2012 Elsevier B.V. All rights reserved.

TI Gene-Centric Meta-Analysis of Lipid Traits in African, East Asian and Hispanic Populations SO PLOS ONE LA English DT Article ID INTERCELLULAR-ADHESION MOLECULE-1; DENSITY-LIPOPROTEIN-CHOLESTEROL; SINGLE-NUCLEOTIDE POLYMORPHISM; NUTRITION EXAMINATION SURVEY; 3RD NATIONAL-HEALTH; CHAIN FATTY-ACIDS; METABOLIC SYNDROME; ASSOCIATION RESOURCE; NATURAL-SELECTION; YOUNG-ADULTS AB Meta-analyses of European populations has successfully identified genetic variants in over 100 loci associated with lipid levels, but our knowledge in other ethnicities remains limited. To address this, we performed dense genotyping of similar to 2,000 candidate genes in 7,657 African Americans, 1,315 Hispanics and 841 East Asians, using the IBC array, a custom similar to 50,000 SNP genotyping array. Meta-analyses confirmed 16 lipid loci previously established in European populations at genome-wide significance level, and found multiple independent association signals within these lipid loci. Initial discovery and in silico follow-up in 7,000 additional African American samples, confirmed two novel loci: rs5030359 within ICAM1 is associated with total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) (p = 8.8x10(-7) and p = 1.5x10(-6) respectively) and a nonsense mutation rs3211938 within CD36 is associated with high-density lipoprotein cholesterol (HDL-C) levels (p = 13.5x10(-1)2). The rs3211938-G allele, which is nearly absent in European and Asian populations, has been previously found to be associated with CD36 deficiency and shows a signature of selection in Africans and African Americans. Finally, we have evaluated the effect of SNPs established in European populations on lipid levels in multi-ethnic populations and show that most known lipid association signals span across ethnicities. However, differences between populations, especially differences in allele frequency, can be leveraged to identify novel signals, as shown by the discovery of ICAM1 and CD36 in the current report.

TI Leptin differentially regulate STAT3 activation in ob/ob mouse adipose mesenchymal stem cells SO NUTRITION & METABOLISM LA English DT Article DE Obesity; Adipose stem cell; Leptin ID NF-KAPPA-B; CHRONIC INFLAMMATION; INSULIN-RESISTANCE; IMMUNE-RESPONSES; PROGENITOR CELLS; WEIGHT-LOSS; IN-VITRO; RECEPTOR; TISSUE; MICE AB Background: Leptin-deficient ob/ob mice exhibit adipocyte hypertrophy and hyperplasia as well as elevated adipose tissue and systemic inflammation. Multipotent stem cells isolated from adult adipose tissue can differentiate into adipocytes ex vivo and thereby contribute toward increased adipocyte cell numbers, obesity, and inflamm ation. Currently, information is lacking regarding regulation of adipose stem cell numbers as well as leptin-induced inflammation and its signaling pathway in ob/ob mice. Methods: Using leptin deficient ob/ob mice, we investigated whether leptin injection into ob/ob mice increases adipose stem cell numbers and adipose tissue inflammatory marker MCP-1 mRNA and secretion levels. We also determined leptin mediated signaling pathways in the adipose stem cells. Results: We report here that adipose stem cell number is significantly increased following leptin injection in ob/ob mice and with treatment of isolated stem cells with leptin in vitro. Leptin also up-regulated MCP-1 secretion in a dose-and time-dependent manner. We further showed that increased MCP-1 mRNA levels were due to increased phosphorylation of Signal Transducer and Activator of Transcription 3 (STAT3) Ser727 but not STAT3 Tyr705 phosphorylation, suggesting differential regulation of MCP-1 gene expression under basal and leptin-stimulated conditions in adipose stem cells. Conclusions: Taken together, these studies demonstrate that leptin increases adipose stem cell number and differentially activates STAT3 protein resulting in up-regulation of MCP-1 gene expression. Further studies of mechanisms mediating adipose stem cell hyperplasia and leptin signaling in obesity are warranted and may help identify novel anti-obesity target strategies.

TI Generation of the Volatile Spiroketals Conophthorin and Chalcogran by Fungal Spores on Polyunsaturated Fatty Acids Common to Almonds and Pistachios SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE Aspergillus; chalcogran; conophthorin; fatty acid; germination; Penicillium; Rhizopus; spiroacetal; spiroketal; spore; volatile ID BARK BEETLES; NAVEL ORANGEWORM; TREE NUTS; BIOSYNTHESIS; COMPONENTS; PHEROMONE AB The spiroketal (E)-conophthorin has recently been reported as a semiochemical of the navel orangeworm moth, a major insect pest of California pistachios and almonds. Conophthorin and the isomeric spiroketal chalcogran are most commonly known as semiochemicals of several scolytid beetles. Conophthorin is both an insect- and plant-produced semiochemical widely recognized as a nonhost plant volatile from the bark of several angiosperm species. Chalcogran is the principal aggregation pheromone component of the six-spined spruce bark beetle. Recent research has shown conophthorin is produced by almonds undergoing hull-split, and both spiroketals are produced by mechanically damaged almonds. To better understand the origin of these spiroketals, the volatile emissions of orchard fungal spores on fatty acids common to both pistachios and almonds were evaluated. The volatile emission for the first 13 days of spores placed on a fatty acid was monitored. The spores investigated were Aspergillus flavus (atoxigenic), A. flavus (toxigenic), Aspergillus niger, Aspergillus parasiticus, Penicillium glabrum, and Rhizopus stolonifer. The fatty acids used as growth media were palmitic, oleic, linoleic, and linolenic. Spores on linoleic acid produced both spiroketals, those on linolenic acid produced only chalcogran, and those on palmitic and oleic acid did not produce either spiroketal. This is the first report of the spiroketals conophthorin and chalcogran from a fungal source. C1 [Beck, John J.; Mahoney, Noreen E.; Gee, Wai S.] ARS, Western Reg Res Ctr, USDA, Albany, CA 94710 USA.

Ten organic and ten conventional peppermint samples were examined using HPLC-UV and FIMS methods. Principal component analysis (PCA) showed that both HPLC and FIMS fingerprints could determine the difference in the commercial organic and conventional peppermints. FIMS fingerprinting provided a rapid test to differentiate organic and conventional peppermints in 1 min of analysis and has potential for high-throughput applications. On the other hand, HPLC fingerprints provide more information about the chemical composition of the samples, but take a longer time to differentiate organic and conventional peppermint samples.

Two proteins, Rep and Rep', are essential for PCV DNA replication in mammalian cells. In this work, replicative intermediates of PCV-infected porcine kidney (PK15) cells or copy-release of PCV genomes from a head-to-tail tandem construct (without Rep') in Escherichia coli were examined. In PK15 cells, replicative intermediates consistent with complementary-strand replication which converts single-stranded circular genome to double-stranded supercoiled DNA and RCR which generates single-stranded plus strand progeny genome were observed. To a lesser extent, intermediates suggestive of recombination-dependent replication were also detected. In Escherichia coli, copy release of the single-stranded circular PCV genome with conversion to a supercoiled molecule by complementary-strand synthesis was observed. However, replicative intermediates indicative of RCR were not detected. Published by Elsevier Inc. C1 USDA ARS, Virus & Prion Dis Livestock Res Unit, Natl Anim Dis Ctr, Ames, IA 50010 USA.

TI Thermal properties of poly(ethylene terephthalate) recovered from municipal solid waste by steam autoclaving SO JOURNAL OF APPLIED POLYMER SCIENCE LA English DT Article DE polyesters; recycling; separation techniques; thermal properties; waste AB The steam autoclaving of municipal solid waste followed by size separation was shown to be a way to recover virtually 100% of recyclable poly(ethylene terephthalate) (PET); this is a yield not attainable by a typical material recovery facility. The polymer properties of the recovered PET, which had undergone various degrees of thermal processing, were evaluated by thermogravimetric analysis, differential scanning calorimetry, gel permeation chromatography, viscometry, and solid-state NMR to assess the commercial viability of polymer reuse. The weight-average molecular weight (Mw) decreased as a result of autoclaving from 61,700 g/mol for postconsumer poly(ethylene terephthalate) (pcPET) to 59,700 g/mol for autoclaved postconsumer poly(ethylene terephthalate) [(apcPET)]. Mw for the reclaimed poly(ethylene terephthalate) (rPET) was slightly lower, at 57,400 g/mol. The melting temperature increased with two heat cycles from 236 degrees C for the heat-crystallized virgin poly(ethylene terephthalate) (vPET) pellets to 248 degrees C for apcPET and up to 253 degrees C for rPET. Correspondingly, the cold crystallization temperature decreased with increased processing from 134 degrees C for vPET to 120 degrees C for apcPET. The intrinsic viscosity varied from 0.773 dL/g for the vPET to 0.709 dL/g for rPET. Extruded samples were created to assess the potential commercial applications of the recovered rPET samples. The Mw values of the extruded apcPET and rPET samples dropped to 37,000 and 34,000 g/mol, respectively, after extrusion (three heat cycles); this indicated that exposure to heat dictated that these materials would be better suited for downcycled products, such as fibers and injected-molded products.

The polymers were prepared by synthesizing polymer gels that were subsequently cured at 125 degrees C to form polymer films. The polymers were evaluated for the extent of reaction before and after curing by Fourier transform infrared spectroscopy. They were subsequently immersed in dimethylsulfoxide, tetrahydrofuran, water, methanol, and hexane for 24 h. The amounts of solvent absorbed were monitored and recorded. Dependent up the solvent used, the polymers were able to absorb 9.5261% of its weight. The effects of the solvent absorption on the viscoelastic properties of the polyester films were evaluated by determining their elastic modulus (G'), viscous modulus (G?), tan dG?/G', and complex viscosity (?*) by performing oscillatory frequency sweep experiments. The elastic modulus (G') and viscous modulus (G?) were both higher for the dry polymers than the solvent-absorbed polymers. However, the polymer films were all higher in elastic (G') character than viscous (G?) character. Therefore, tan dG?/G' < 1 before and after immersion in solvents. Values for ?* decreased with angular frequency for all of the polyesters tested in this study. (c) 2012 Wiley Periodicals, Inc.

Recent clinical studies reveal that supplementation of oligofructans promotes weight loss by suppressing ghrelin and increasing peptide YY in overweight and obese adults. Thus, greater consumption of vegetables and fruits rich in oligofructans may improve health conditions, which is particularly important for Mississippi as it has one of the highest rates of obesity and diabetes in the United States. Species belonging to the Asteraceae family including yacon, Smallanthus sonchifolius, are particularly rich sources of stored inulin and oligofructans in their storage roots and rhizophores (the underground storage organs). Thus, we cultivated yacon in North Mississippi as a specialty crop: expecting that in the near future fresh yacon could be introduced as a functional food to supplement the diet of Mississippians treating diet related chronic diseases. We evaluated the quality of leaves harvested in mid-November based on the content of chlorogenic and 3,5-dicaffeoylquinic acids and the fructan yields in roots and rhizophores. After the leaves were damaged by frost, the content of oligofructans was reduced affecting the quality of the tuberous roots and rhizophores. Estimated yield based on the relative fresh weight of plants harvested on November 17, before the frost, was 73.1 t/ha of underground parts from which 25.6 t/ha produced roots and 47.5 t/ha rhizophores.

SIT has been used to control major pest insects including the pink bollworm (Pectinophora gossypiella Saunders), a global pest of cotton. Transgenic technology has the potential to overcome disadvantages associated with the SIT, such as the damaging effects of radiation on released insects. A method called RIDL (Release of Insects carrying a Dominant Lethal) is designed to circumvent the need to irradiate insects before release. Premature death of insects' progeny can be engineered to provide an equivalent to sterilisation. Moreover, this trait can be suppressed by the provision of a dietary antidote. In the pink bollworm, we generated transformed strains using different DNA constructs, which showed moderate-to-100% engineered mortality. In permissive conditions, this effect was largely suppressed. Survival data on cotton in field cages indicated that field conditions increase the lethal effect. One strain, called OX3402C, showed highly penetrant and highly repressible lethality, and was tested on host plants where its larvae caused minimal damage before death. These results highlight a potentially valuable insecticide-free tool against pink bollworm, and indicate its potential for development in other lepidopteran pests.

The plan included a variety of wild bird sampling strategies including the testing of fecal samples from aquatic areas throughout the United States from April 2006 through December 2007. Although HPAIV was not detected through this surveillance effort we were able to obtain 759 fecal samples that were positive for low pathogenic avian influenza virus (LPAIV). We used 136 DNA sequences obtained from these samples along with samples from a public influenza sequence database for a phylogenetic assessment of hemagglutinin (HA) diversity in the United States. We analyzed sequences from all HA subtypes except H5, H7, H14 and H15 to examine genetic variation, exchange between Eurasia and North America, and geographic distribution of LPAIV in wild birds in the United States. This study confirms intercontinental exchange of some HA subtypes (including a newly documented H9 exchange event), as well as identifies subtypes that do not regularly experience intercontinental gene flow but have been circulating and evolving in North America for at least the past 20 years. These HA subtypes have high levels of genetic diversity with many lineages co-circulating within the wild birds of North America. The surveillance effort that provided these samples demonstrates that such efforts, albeit labor-intensive, provide important information about the ecology of LPAIV circulating in North America.

One approach for the remote sensing of FMC has been to estimate the change in canopy water content over time by using a liquid-water spectral index. Recently, the normalized dry matter index (NDMI) was developed for the remote sensing of dry matter content using high-spectral-resolution data. The ratio of a spectral water index and a dry matter index corresponds to the ratio of foliar water and dry matter contents; therefore, we hypothesized that FMC may be remotely sensed with a spectral water index divided by NDMI. For leaf-scale simulations using the PROSPECT (leaf optical properties spectra) model, all water index/NDMI ratios were significantly related to FMC with a second-order polynomial regression. For canopy-scale simulations using the SAIL (scattering by arbitrarily inclined leaves) model, two water index/NDMI ratios, with numerators of the normalized difference infrared index (NDII) and the normalized difference water index (NDWI), predicted FMC with R-2 values of 0.900 and 0.864, respectively. Leaves from three species were dried or stacked to vary FMC; measured NDII/NDMI was best related to FMC. Whereas the planned NASA mission Hyperspectral Infrared Imager (HyspIRI) will have high spectral resolution and very high signal-to-noise properties, the planned 19-day repeat frequency will not be sufficient for monitoring FMC with NDII/NDMI. Because increased fire frequency is expected with climatic change, operational assessment of FMC at large scales may require polar-orbiting environmental sensors with narrow bands to calculate NDMI.

Aberrantly activated Wnt signaling can result in the abnormal stabilization of beta-catenin, a key causative step in a broad spectrum of cancers. Here we report the modulation of lithium chloride-activated canonical Wnt/beta-catenin signaling by phytochemicals that have antioxidant, anti-inflammatory or chemopreventive properties. The compounds were first screened with a cervical cancer-derived stable Wnt signaling reporter HeLa cell line. Positive hits were subsequently evaluated for beta-catenin degradation, suppression of beta-catenin nuclear localization and down-regulation of downstream oncogenic targets of Wnt/beta-catenin pathway. Our study shows a novel degradation path of beta-catenin protein in HeLa cells by Avenanthramide 2p (a polyphenol) and Triptolide (a diterpene triepoxide), respectively from oats and a Chinese medicinal plant. The findings present Avenanthramide 2p as a potential chemopreventive dietary compound that merits further study using in vivo models of cancers; they also provide a new perspective on the mechanism of action of Triptolide.

GeneDisc real-time PCR assays were evaluated for detection of the stx(1), stx(2), eae, and ehxA genes and a gene that identifies the 0157 serogroup followed by a second GeneDisc assay targeting serogroup-specific genes of STEC 026, 045, 091, 0103, 0111, 0113, 0121, 0145, and 0157 The ability to detect the STEC serogroups in ground beef samples artificially inoculated at a level of ca. 2-20 CFU/25 g and subjected to enrichment in mTSB or buffered peptone water (BPVV) was similar. Following enrichment, all inoculated ground beef samples showed amplification of the correct set of target genes carried by each strain. Samples inoculated with STEC serogroups 026, 045, 0103, 0111, 0121, 0145, and 0157 were subjected to immunomagnetic separation (IMS), and isolation was achieved by plating onto Rainbow agar 0157 Colonies were confirmed by PCR assays targeting stx(1), stx(2), eae, and serogroup-specific genes. Thus, this work demonstrated that GeneDisc assays are rapid, sensitive, and reliable and can be used for screening ground beef and potentially other foods for STEC serogroups that are important food-borne pathogens worldwide.

Sauteing or steam cooking has been observed to significantly improve bile acid binding of green/leafy vegetables. It was hypothesized that microwave cooking could improve the bile acid binding of various vegetables. Microwave cooking with no added water resulted in bile acid binding measured on a dry matter basis relative to cholestyramine of 13% for kale and mustard greens, 9% for broccoli and collard greens, 4% for cabbage, and 2% for green bell pepper. These results point to the significantly different (P <= 0.05) health promoting potential of kale = mustard greens > broccoli = collard greens > cabbage > green bell pepper. Microwave cooking with no added water significantly improved in vitro bile acid binding of kale, mustard greens, broccoli and cabbage compared with microwave cooking with added water or raw (uncooked). For green bell pepper, binding values were similar when microwave cooked with or without added water and significantly higher than uncooked. In the case of collard greens, bile acid binding values were similar for raw or microwave cooked with added water and were significantly lowered by microwave cooking with no added water. Microwave cooking with no added water should be used for kale, mustard greens, broccoli and cabbage; for collard greens and green bell pepper microwave with added water as the cooking method. These green/leafy vegetables, when consumed regularly after microwave cooking would promote a healthy lifestyle, keep dietary fat low, and have the potential to lower the risk of premature degenerative diseases.

But a relatively new cell system using progeny cells stemming from the dedifferentiation of purified cultures of mature adipocytes may be used for studying the development and biology of adipocytes. In this research, we show that isolated (and purified) mature adipocytes derived from Wagyu cattle dedifferentiate into progeny cells, and that these spindle-shaped, proliferative-competent daughter cells possess ability to proliferate. We outline the optimum cell culture system and offer precautionary thoughts for effective mature adipocyte culture. Collectively, this represents a novel cell model which may provide new insights into cell development, physiology and use as a model for animal production/composition, tissue engineering and disease treatment.

TI Relationship of Resistance to Meloidogyne chitwoodi (race 2) and M. hapla in Alfalfa SO JOURNAL OF NEMATOLOGY LA English DT Article DE alfalfa; host status; Meloidogyne chitwoodi; Meloidogyne hapla; pest resistance ID POPULATION-DENSITIES; NEMATODES; SEEDLINGS; POTATO; GROWTH; YIELD; SOIL AB In the Pacific Northwest, alfalfa (Medicago sativa) is host to two species of root-knot nematodes, including race 2 of the Columbia root-knot nematode (Meloidogyne chitwoodi) and the northern root-knot nematode (Meloidogyne hapla). In addition to the damage caused to alfalfa itself by M. hapla, alfalfa's host status to both species leaves large numbers of nematodes available to damage rotation crops, of which potato is the most important. A nematode-resistant alfalfa germplasm release, W12SR2W1, was challenged with both nematode species, to determine the correlation, if any, of resistance to nematode reproduction. Thirty genotypes were screened in replicated tests with M. chitwoodi race 2 or M. hapla, and the reproductive factor (RF) was calculated. The distribution of natural log-transformed RF values was skewed for both nematode species, but more particularly for M. chitwoodi race 2, where more than half the genotypes screened were non-hosts. Approximately 30 percent of genotypes were non-hosts or very poor hosts of M. hapla, but RF values for M. hapla on susceptible genotypes were generally much higher than RF values for genotypes susceptible to M. chitwoodi race 2. The Spearman rank correlation was positive (0.52) and significant (p-value = 0.003), indicating there is some relationship between resistance to these two species of root-knot nematode in alfalfa. However the relationship is not strong enough to suggest genetic loci for resistance are identical, or closely linked. Breeding for resistance or immunity will require screening with each species separately, or with different DNA markers if marker-assisted breeding is pursued. A number of genotypes were identified which are non-hosts to both species. These plants will be intercrossed to develop a non-host germplasm.

TI Observations on the Foliar Nematode, Aphelenchoides besseyi, Infecting Tuberose and Rice in India SO JOURNAL OF NEMATOLOGY LA English DT Article DE Aphelenchoides besseyi; diagnosis; distribution; host; India; morphology; rice; tuberose AB The foliar nematode Aphelenchoides besseyi causes white tip disease in rice (Oryza sativa L.) and floral malady in tuberose (Polianthes tuberosa L.). This nematode is widely distributed in the rice fields of many states of India, including West Bengal (WB), Andhra Pradesh (AP), Madhya Pradesh (MP) and Gujarat (GT). In order to generate information on intraspecific variations of A. besseyi as well as to confirm the identity of the nematode species infecting these important crops, morphological observation was undertaken of A. besseyi isolated from tuberose and rice from WB and rice from AP, MP and GT. The molecular study was only done for rice and tuberose populations from AP and WB. The variations were observed among the populations in the tail, esophageal and anterior regions, including the occurrence of four as well as six lateral lines in the lateral fields. The morphometrics of observed populations showed variations and those could be regarded as a consequence of host-induced or geographical variations. PCR amplification of the rDNA ITS 1 and 2 region of rice (AP) and tuberose (WB) populations of A. besseyi generated one fragment of approximately 830 bp, and the size of the ITS region was 788 bp and 791 bp for tuberose and rice population, respectively. Alignment of the two sequences showed almost 100% similarity. Blast analysis revealed a very high level of similarity of both the Indian strains to a Russian population. The Indian and Russian strains could be differentiated using restriction enzyme Bccl. Host tests revealed that rice (cv. IET 4094), oat (cv. OS-6) and teosinte (cv. TL-1) showed a typical distortion due to the infection of A. besseyi. Five germplasm lines of oat showed no infection of the nematode under field conditions. Local cultivars of onion, maize, chrysanthemum, gladiolus, and Sorghum halepense were also not infected by A. besseyi.

TI Chromium supplementation alters both glucose and lipid metabolism in feedlot cattle during the receiving period SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE chromium propionate; glucose metabolism; glucose tolerance test; insulin sensitivity test; lipid metabolism; receiving cattle ID CALCIUM PROPIONATE; IMMUNE-RESPONSE; FEEDER CALVES; PICOLINATE; PERFORMANCE; TRIPICOLINATE; RESISTANCE; GROWTH; STEERS; LAMBS AB Crossbred steers (n = 20; 235 +/- 4 kg) were fed for 53 d during a receiving period to determine if supplementing chromium (Cr; KemTRACE Chromium Propionate 0.04%, Kemin Industries, Des Moines, IA) would alter glucose or lipid metabolism of newly received cattle. Chromium premixes were supplemented to add 0 (Con) or 0.2 mg/kg of Cr to the total diet on a DM basis. Cattle were fitted with jugular catheters on d 52. A glucose tolerance test (GTT) and an insulin sensitivity test (IST) were conducted on d 53. Blood samples were collected from -60 to 150 min relative to each infusion. Serum was isolated to determine glucose, insulin, and NEFA concentrations. Throughout GTT, no differences were detected in glucose concentrations, glucose clearance rates (k), or preinfusion insulin concentrations (P > 0.50), but insulin concentrations postinfusion tended (P = 0.06) to be greater for the Cr-supplemented steers. This caused an increase in the insulin to glucose ratio (I: G) from 0 to 150 min postinfusion for the Cr-supplemented steers (P = 0.03). In addition, NEFA concentrations during GTT were lower (P <= 0.01) for Cr-supplemented steers both preinfusion and postinfusion. During IST, there was no treatment effect on glucose concentrations preinfusion (P = 0.38), but postinfusion glucose concentrations were greater (P< 0.01) in the Cr-supplemented steers. The k of Cr-supplemented steers tended (P = 0.06) to be faster than Con steers from 30 to 45 min postinfusion. During the same test, there was no treatment effect detected for insulin concentrations (P > 0.33). The I: G were not affected by treatment (P > 0.40). Concentrations of NEFA were reduced (P < 0.01) both preinfusion and postinfusion during IST for Cr-supplemented steers. Results of this study indicate that supplementation of Cr can significantly alter lipid metabolism. This suggests that these steers had less dependence on lipid metabolism for energy or sensitivity of adipose tissue to antilipolytic signals was reduced. Results of glucose and insulin metabolism were inconsistently modified after a GTT and an IST. C1 [Bernhard, B. C.; Rathmann, R. J.; Finck, D. N.; Jennings, M. A.; Young, T. R.; Johnson, B.

The study was conducted as a randomized complete block with a 2 x 2 factorial arrangement of treatments. Dietary treatments included steam-flaked corn (SFC)- and dry-rolled corn (DRC)-based finishing diets containing 0 or 20% WDGS (0SFC, 20SFC, 0DRC, and 20DRC, respectively). Heifers averaged 154 d on feed and were marketed in 3 groups. There were no interactions between corn processing method and WDGS detected (P >= 0.29) for any performance or carcass response variables. Heifers fed diets containing WDGS tended to have greater final BW (P = 0.10) and increased G: F (P = 0.08) compared with heifers fed diets without WDGS. Heifers fed SFC-based diets consumed 7% less feed (P < 0.01) and were 9% more efficient (P < 0.01) than heifers fed DRC-based diets. Carcass characteristics were not affected by corn processing method or WDGS inclusion (P >= 0.16). Intakes of OM, N, P, and K were greater (P <= 0.05) for heifers fed DRC-based diets than those fed SFC-based diets, which resulted in greater net accumulation of the nutrients in the manure (P <= 0.04). Heifers fed diets containing WDGS had greater (P < 0.01) intakes of N, P, and K than heifers fed diets without WDGS. As a result, a greater net accumulation of P and K (P <= 0.03) and N (P = 0.10) were present in the manure from cattle fed diets containing WDGS compared with those fed diets without WDGS. There was no interaction (P >= 0.16) between corn processing and WDGS on N volatilization losses. Nitrogen volatilization losses from manure (expressed as a percentage of intake and g.heifer(-1).d(-1)) were greater (P < 0.01) for heifers fed SFC-based diets than heifers fed DRC-based diets. Feeding DRC-based finishing diets to heifers resulted in increased manure production and nutrient excretion and decreased N volatilization. Both corn processing method and WDGS inclusion affected animal performance and manure characteristics. C1 [Buttrey, E. K.; Jenkins, K. H.; Meyer, B. E.; Preece, S. L. M.; Auvermann, B.

TI Winter protein management during late gestation alters range cow and steer progeny performance SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE beef cattle; fetal programming; protein supplementation; reproduction ID BEEF-COWS; FEEDLOT PERFORMANCE; EFFICIENCY; NUTRITION; ENERGY AB A 4-yr study was conducted at Corona Range and Livestock Research Center, Corona, NM, to establish if a protein-dense self-fed supplement could substitute for a traditional hand-fed (range cube) supplement that is less protein dense and minimize or maintain cow BW and BCS during late gestation and the subsequent steer progeny feedlot performance, health, and economic viability. Late gestation cows received one of 3 supplementation strategies: 1) 36% CP cottonseed meal base supplement (CSM; positive control) fed 3 times per week, 2) self-fed supplement (SMP) comprising 50% animal protein sources (blood meal and feather meal) and 50% trace mineral package, or 3) brief and intermittent supplementation of CSM based on periods of acute environmental stress (VAR; negative control) by ranch management. Initiation of supplementation varied across years due to changing forage conditions and climatically imposed grazing constraints but always ended approximately 2 wks before calving each year. Across all 4 yr, supplement consumption averaged 0.65, 0.21, and 0.04 kg.head(-1).d(-1) for CSM, SMP, and VAR, respectively. After weaning, steers were preconditioned for 45 d and were received and treated as custom fed commercial cattle at a feedlot in mid November each year. Cow BW and BCS were not influenced (P >= 0.13) by prepartum supplementation; however, the strategy did have an effect on BW and BCS change with cows managed in the VAR group. Cows managed in the VAR group lost the greatest (P < 0.05) amount of BW and BCS whereas no differences were measured between CSM and SMP groups. Prepartum supplementation strategies did not influence (P = 0.98) pregnancy rates. Calf weaning, initial feedlot and final BW, and HCW were unaffected (P >= 0.80) by prepartum supplementation of the dam. Steers from dams fed CSM and VAR had a greater percentage treated for sickness than SMP steers (P = 0.03), which resulted in a tendency (P = 0.07) for medicine costs to be greater in steers from CSM and VAR cows. The use of a self-fed package supplement was equally effective as use of a traditional hand-fed, oilseed-based supplement in maintaining BW and BCS during late gestation. In addition, these results imply that although nutrition treatment of cows during the prenatal period had no effect on calf growth performance, calves from cows fed SMP had improved feedlot health.

TI National Beef Quality Audit-2011: Harvest-floor assessments of targeted characteristics that affect quality and value of cattle, carcasses, and byproducts SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE audit; beef quality; carcass ID ESCHERICHIA-COLI O157-H7; RESPIRATORY-DISEASE; FEEDLOT CATTLE; QUANTITY ATTRIBUTES; TREATMENT RECORDS; PROCESSING PLANT; FED STEERS; SLAUGHTER; IMPACT; CONTAMINATION AB The National Beef Quality Audit-2011 (NBQA-2011) was conducted to assess targeted characteristics on the harvest floor that affect the quality and value of cattle, carcasses, and byproducts. Survey teams evaluated approximately 18,000 cattle/carcasses between May and November 2011 in 8 beef processing facilities. Cattle identification methods were lot visual tags (85.7%), individual visual tags (50.6%), electronic tags (20.1%), metal-clip tags (15.7%), other (5.3%), none (2.5%), and wattles (0.5%). Hide colors or breed types were black (61.1%), red (12.8%), yellow (8.7%), Holstein (5.5%), brown (5.0%), gray (5.0%), white (1.4%), and brindle (1.0%). Brand frequencies were none (55.2%), 1 (40.4%), 2 (4.4%), and 3 or more (0.04%) brands, and brands were located on the butt (35.2%), side (9.0%), and shoulder (2.5%). Hide locations of mud or manure were no mud/manure (49.2%), legs (36.8%), belly (23.7%), side (14.9%), top-line (11.0%), and tail region (13.7%). There were 76.2% of cattle without horns, and the majority of those with horns (71.6%) were between 0 cm and 12.7 cm in length. Permanent incisor numbers were zero (87.3%), 1 (1.4%), 2 (8.0%), 3 (0.9%), 4 (1.9%), 5 (0.3%), 6 (0.2%), 7 (0.1%), and 8 (0.02%). Most carcasses (77.0%) were not bruised, 18.7% had 1 bruise, 3.4% had 2 bruises, 0.6% had 3 bruises, and 0.3% had more than 3 bruises. Bruise locations were loin (50.1%), rib (21.3%), chuck (13.8%), round (7.3%), and brisket/flank/plate (7.5%). Condemnation item and incidence were whole carcass (none recorded), liver (20.9%), lungs (17.3%), tongue (10.0%), viscera (9.3%), and head (7.2%). Compared with the NBQA-2005, the NBQA-2011 had an increased percentage of black-hided cattle (56.3 vs. 61.1%), more cattle with brands (38.7 vs. 44.8%), and more cattle with some form of identification (93.3 vs. 97.5%). In addition, there was a lesser percentage of carcasses with bruising in 2011 (23.0%) than in 2005 (35.2%), as well as a smaller percentage of carcasses with more than 1 bruise (2005 = 9.4% vs. 2011 = 4.2%). Compared with the 2005 audit, a similar percentage of the cattle were deemed 30 mo of age or older using dentition (2005 = 2.7% vs. 2011 = 3.3%).

TI National Beef Quality Audit-2011: In-plant survey of targeted carcass characteristics related to quality, quantity, value, and marketing of fed steers and heifers SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE beef quality; carcass; market survey; meat grade ID PRODUCER-RELATED DEFECTS; ZILPATEROL HYDROCHLORIDE; CATTLE; ATTRIBUTES; TRAITS AB The 2011 National Beef Quality Audit (NBQA-2011) assessed the current status of quality and consistency of fed steers and heifers. Beef carcasses (n = 9,802), representing approximately 10% of each production lot in 28 beef processing facilities, were selected randomly for the survey. Carcass evaluation for the cooler assessment of this study revealed the following traits and frequencies: sex classes of steer (63.5%), heifer (36.4%), cow (0.1%), and bullock (0.03%); dark cutters (3.2%); blood splash (0.3%); yellow fat (0.1%); calloused rib eye (0.05%); overall maturities of A (92.8%), B (6.0%), and C or greater (1.2%); estimated breed types of native (88.3%), dairy type (9.9%), and Bos indicus (1.8%); and country of origin of United States (97.7%), Mexico (1.8%), and Canada (0.5%). Certified or marketing program frequencies were age and source verified (10.7%), <= A(40) (10.0%), Certified Angus Beef (9.3%), Top Choice (4.1%), natural (0.6%), and Non-Hormone-Treated Cattle (0.5%); no organic programs were observed. Mean USDA yield grade (YG) traits were USDA YG (2.9), HCW (374.0 kg), adjusted fat thickness (1.3 cm), LM area (88.8 cm2), and KPH (2.3%). Frequencies of USDA YG distributions were YG 1, 12.4%; YG 2, 41.0%; YG 3, 36.3%; YG 4, 8.6%; and YG 5, 1.6%. Mean USDA quality grade (QG) traits were USDA quality grade (Select(93)), marbling score (Small(40)), overall maturity (A(59)), lean maturity (A(54)), and skeletal maturity (A(62)). Frequencies of USDA QG distributions were Prime, 2.1%; Choice, 58.9%; Select, 32.6%; and Standard or less, 6.3%. Marbling score distribution was Slightly Abundant or greater, 2.3%; Moderate, 5.0%; Modest, 17.3%; Small, 39.7%; Slight, 34.6%; and Traces or less, 1.1%. Carcasses with QG of Select or greater and YG 3 or less represented 85.1% of the sample. This is the fifth benchmark study measuring targeted carcass characteristics, and information from this survey will continue to help drive progress in the beef industry. Results will be used in extension and educational programs as teaching tools to inform beef producers and industry professionals of the current state of the U.S. beef industry. C1 [Moore, M.

TI National Beef Quality Audit-2011: Survey of instrument grading assessments of beef carcass characteristics SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE beef quality; carcass; instrument grading; market survey; meat grade ID PRODUCER-RELATED DEFECTS; DARK-CUTTING BEEF; QUANTITY ATTRIBUTES; TARGETED CATTLE; FED STEERS; AUGMENTATION; THICKNESS; HEIFERS AB The instrument grading assessments for the 2011 National Beef Quality Audit evaluated seasonal trends of beef carcass quality and yield attributes over the course of the year. One week of instrument grading data, HCW, gender, USDA quality grade (QG), and yield grade (YG) factors, were collected every other month (n = 2,427,074 carcasses) over a 13-mo period (November 2010 through November 2011) from 4 beef processing corporations, encompassing 17 federally inspected beef processing facilities, to create a "snapshot" of carcass quality and yield attributes and trends from carcasses representing approximately 8.5% of the U.S. fed steer and heifer population. Mean yield traits were YG (2.86), HCW (371.3 kg), fat thickness (1.19 cm.), and LM area (88.39 cm(2)). The YG distribution was YG 1, 15.7%; YG 2, 41.0%; YG 3, 33.8%; YG 4, 8.5%; and YG 5, 0.9%. Distribution of HCW was <272.2 kg, 1.6%; 272.2 to 453.6 kg, 95.1%; and >= 453.6 kg, 3.3%. Monthly HCW means were November 2010, 381.3 kg; January 2011, 375.9 kg; March 2011, 366.2 kg; May 2011, 357.9 kg; July 2011, 372.54 kg; September 2011, 376.1 kg; and November 2011, 373.5 kg. The mean fat thickness for each month was November 2010, 1.30 cm; January 2011, 1.22 cm; March 2011, 1.17 cm; May 2011, 1.12 cm; July 2011, 1.19 cm; September 2011, 1.22 cm; and November 2011, 1.22 cm. The overall average marbling score was Small(49). The USDA QG distribution was Prime, 2.7%; Top Choice, 22.9%; Commodity Choice, 38.6%; and Select, 31.5%. Interestingly, from November to May, seasonal decreases (P < 0.001) in HCW and fat thicknesses were accompanied by increases (P < 0.001) in marbling. These data present the opportunity to further investigate the entire array of factors that determine the value of beef. Data sets using the online collection of electronic data will likely be more commonly used when evaluating the U.S. fed steer and heifer population in future studies. C1 [Gray, G. D.; Moore, M.

TI Effect of immune system stimulation and divergent selection for residual feed intake on digestive capacity of the small intestine in growing pigs SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE ileal digestibility; immune system stimulation; nutrient transport; residual feed intake ID RATS; MUCINS AB Little is known of the consequences of divergent selection for residual feed intake (RFI) on intestinal digestion capacity, particularly during immune system stimulation (ISS). Our objective was to evaluate the impact of ISS and divergent selection for RFI on apparent ileal digestibility (AID) and apparent fecal digestibility (AFD) of nutrients and intestinal nutrient active transport and barrier function. Twenty-eight gilts (63 +/- 4 kg BW) from low RFI (LRFI; n = 14) and high RFI (HRFI; n = 14) Yorkshire lines were randomly selected from the Iowa State University RFI herd. Following adaptation, 8 pigs in each line were injected intramuscularly and every 48 h for 7 d with increasing amounts of Escherichia coli lipopolysaccharide (ISS+). Remaining pigs were injected with saline (ISS-). Pigs were then euthanized and ileal digesta was collected for measuring AID of nutrients. Fecal samples were collected on a daily basis and pooled for measuring AFD of nutrients. A segment of ileum was used to measure nutrient transport and transepithelial resistance (TER) and/or barrier integrity by Ussing chambers. No effects of line or its interaction with ISS on AID of CP (N x 6.25) and OM, TER, and active nutrients transport were observed. However, ISS decreased (P < 0.05) and tended to (P < 0.1) decrease AID of CP and OM, respectively. Decrease in AFD of CP as result of ISS was greater in the LRFI line compared to the HRFI line (P < 0.05). Relative to ISS-, active glucose and P transport was greater in ISS+ pigs (P < 0.05). Genetic selection for LRFI increases the AFD but has no effect on AID of nutrients. It also reduces the total tract digestive capacity of growing pigs during ISS. Immune system stimulation affects both AID and AFD of dietary CP. C1 [Rakhshandeh, A.; Dekkers, J. C. M.; English, J.; Gabler, N. K.] Iowa State Univ, Dept Anim Sci, Ames, IA 50011 USA. [Kerr, B.

Nurseries in Hawaii must follow strict certification requirements to export potted plants to these markets where R. reniformis is not established. Mined volcanic cinder, utilized as a potting medium, may contain reniform nematode and needs to be disinfested for use by nematode certified nurseries. Two steam treatment systems of different capacities were evaluated for their efficacy to disinfest the cinder of R. reniformis. The low capacity system consisted of a portable steam generator connected to a steam cart with a media volume of 1.68 m(3). The large capacity system consisted of a dump truck bed modified with an intake manifold and steam distribution pipes connected to a large capacity steam generating boiler to sterilize a 24.5 m(3) load of media. Packets of nematode-infested cinder containing R. reniformis-infested roots of Ipomoea batatas were buried in various locations and different depths in the cinder contained in the two steaming systems. Temperature probes were placed inside or adjacent to the packets and observed during the sterilization process. The steam did not penetrate and distribute in the medium at a consistent rate in both steaming systems resulting in cold spots. These were identified and monitored to ensure that treatment time was sufficient to reach target temperature throughout the medium mass. Once the steam was evenly distributed both systems were successful at eradicating all live R. reniformis. C1 [Cabos, R. Y. M.] ARS, USDA, US Pacific Basin Agr Res Ctr, Hilo, HI 96720 USA. [Tsang, M.

Rootstocks tested included seedlings derived from open pollinated seed of 'Apache', 'Caddo', 'Curtis', 'Moneymaker', 'Pawnee', 'Schley', 'Stuart', and 'Wichita' parent trees. 'Elliott', a susceptible pecan rootstock for M. partityla, was included as the control. All open pollinated pecan rootstocks supported nematode reproduction as indicated by number of egg masses per plant, number of eggs per plant, and number of eggs per gram dry root, regardless of nematode species. Reproduction by M. partityla was greater(P < 0.05) on all pecan rootstocks than M. incognita and M. arenaria, indicating that pecan is a better host for M. partityla. All pecan seed sources were rated as good hosts (susceptible) to M. partityla infection and as poor hosts (resistant) to M. incognita and M. arenaria. In another greenhouse study, open pollinated 'Elliott' seedlings supported greater (P < 0.01) reproduction of M. partityla than seedlings from Guardian (R), 'Lovell', 'Halford', 'Flordaguard' and 'Nemaguard' peach. All peach rootstocks were rated as non-hosts (highly resistant) to M. partityla infection. Interplanting pecan and peach trees in a commercial orchard environment does not appear to exacerbate the M. partityla population density between the two perennial crops in the southeastern United States.

National legislation for public lands often provides conflicting goals but little guidance for agencies such as the U. S. Forest Service to operationalize public value preferences. The historical difficulty of integrating public values into forest management decisions includes the problems of measurement, aggregation, and tradeoff analysis. In this paper, we present a method for measuring and integrating spatially-explicit public values collected using public participation geographic information systems (PPGIS) into a decision support framework we call values compatibility analysis (VCA). We provide a case study to demonstrate how spatially-explicit public values can be used to determine the compatibility of designating ATV/OHV routes on national forest land. The applications and limitations of VCA for decision support are elaborated and we conclude that an effective decision support framework should provide some degree of standardization, be broadly inclusive, and provide the opportunity to engage in systematic place-based value trade-off analyses.

Three single nucleotide substitutions identified in Domains II and III of the sodium channel gene of R. (B.) microplus are known to be associated with target site pyrethroid resistance. We developed a multiplex PCR using allele-specific primers to amplify wild type or mutated genotypes of the three mutations simultaneously. This assay was used to screen tick samples originating from Brazil, Argentina, Mexico, South Africa and Australia whose phenotype to flumethrin and cypermethrin had been determined by the use of the Larval Tarsal test (LTT) or the Larval Packet Test (LPT). These mutations were found to have distinct geographical distributions and result in different resistance phenotypes. The L64I Domain II mutation conferring resistance to several SP compounds was found in all the Brazilian, Argentinean and Australian populations and in one South African population, with frequencies between 38% and 100% in flumethrin and cypermethrin resistant populations. In contrast, this mutation was not found in samples from Mexico, while the Domain III mutation was found exclusively in this country. The G72V Domain II flumethrin-specific mutation was found in a single Australian population, with a very low resistant allele frequency (3%). The homozygous resistant RR genotype of the L64I Domain II mutation correlated significantly with the survival rates at the discriminating doses of flumethrin and cypermethrin. This survey shows the widespread distribution of the L64I Domain II mutation and provides evidence of its geographic separation from the Domain III mutation.

Luminescence measurements based on quantitation of the ATP present were used to determine the amount of biofilm elimination and correlated with quantity of live bacteria present in the sample. The data were analyzed employing a two-way ANOVA and Bonferroni post-test. Treatments resulted in percentage reductions of E. coli biofilms ranging from 73 to 98 %. Lactoferrin (40 mu g/ml) produced a significantly higher-percentage reduction than lysozyme (10 mu g/ml) (P < 0.05), no other significant differences occurred. Similar treatments resulted in percentage reductions of K. pneumoniae subsp. pneumoniae biofilms ranging from 51 to 100 %. Dextranase treatments produced a significantly lower percentage reduction than all other materials (P < 0.05), no other significant differences occurred. No material was capable of complete destruction of both single species biofilms; however, low concentrations of lactoferrin and lysozyme each removed 100 % of the K pneumoniae subsp. pneumoniae biofilm. Low concentrations of lactoferrin or lysozyme might be beneficial to prevent biofilm formation by K pneumoniae subsp. pneumoniae.

Here we estimate organic carbon stored in diverse valley types of headwater rivers in Rocky Mountain National Park, CO, USA. We show that low-gradient, broad valley bottoms with old-growth forest or active beaver colonies store the great majority of above- and below-ground carbon. These laterally unconfined valley segments constitute <25% of total river length, but store similar to 75% of the carbon. Floodplain sediment and coarse wood dominate carbon storage. Our estimates of riverine carbon storage represent a previously undocumented but important carbon sink. Our results indicate that: not all mountainous rivers rapidly export carbon; not all valley segments are equally important in carbon storage; and historical changes in riverine complexity have likely reduced carbon storage.

A non-wound inoculation technique was developed to evaluate detached mature fruit belonging to U.S. watermelon Pls for resistance to fruit rot caused by P. capsici. Mature fruit were harvested and placed on wire shelves in a walk-in humid chamber [greater than 95% relative humidity (RH), temperature 26 +/- 2 degrees C] and inoculated with a 7-mm agar plug from an actively growing colony of P. capsici. Twenty-four Pls that exhibited resistance in a preliminary evaluation of 205 Pls belonging to the watermelon core collection in 2009 were grown in the field and greenhouse in 2010 and 2011 and evaluated in the walk-in humid chamber. Fruit rot development was rapid on fruit of susceptible controls 'Black Diamond', 'Sugar Baby', and PI 536464. Several accessions including PI 560020, PI 306782, PI 186489, and PI 595203 (all Citrullus lanatus var. lanatus) were highly resistant to fruit rot. One C. colocynthis (PI 388770) and a C. lanatus var. citroides PI (PI 189225) also showed fruit rot resistance. Fruit from Pis that were resistant also had significantly lower amounts of P. capsici DNA/gram of fruit tissue compared with the susceptible commercial cultivars Sugar Baby and Black Diamond. The sources of resistance to Phytophthora fruit rot identified in this study may prove useful in watermelon breeding programs aimed at enhancing disease resistance.

Currently, podophyllotoxin is extracted from the Himalayan mayapple (Podophyllum hexandrum Royle). Some junipers and other species also contain the same natural product and have been explored as a domestic source for this compound. The objective of this study was to screen junipers in the Big Horn Mountains in Wyoming for podophyllotoxin. Twenty junipers (18 accessions of Juniperus horizontalis Moench. and two accessions off. scopulorum Sarg.) were sampled in Mar. 2012 and analyzed for podophyllotoxin. Podophyllotoxin concentration in the samples varied from 0.058% to 0.673% with five accessions having podophylloxin concentration above 0.5%. This study demonstrated wide variation of podophyllotoxin in J. horizontalis and J. scopulorum in the Big Horn Mountains. Some of the accessions had greater than 0.5% podophyllotoxin making them a feasible source for podophyllotoxin extraction.

Four northern-adapted rabbiteye (NRE) selections (US 1043, US 1045, US 1056, US 1057), four rabbiteye standards ('Brightwell', 'Climax', 'Tifblue', 'Woodard'), two rabbiteye x V. constablaei derivatives ('Little Giant', 'Snowflake), and two highbush standards ('Duke', 'Bluecrop') were pollinated under greenhouse conditions with either self-pollen or a multicultivar, bulk-pollen mixture (appropriate to ploidy level and species) to determine the relative requirements for cross-pollination among NRE selections. Fruit set, berry weight, and seed set were subsequently evaluated. The results suggest that NRE selections, in general, exhibit cross-pollination needs intermediate to the parent types such that: rabbiteye > northern rabbiteye > highbush (i.e., rabbiteye has the lowest self-fertility and the greatest need for cross-pollination). Considerable variation existed among the NRE selections tested, which suggests that it might be possible to select clones with good levels of self-fertility, potentially equivalent to that of highbush blueberry.

Yet despite these goals, there is little understanding of the characteristics that are crucial in the development of fire adapted communities. This research seeks to uncover specific aspects of local social context that lead to adaptive capacity for wildfire among communities in Flathead County, MT by consulting local fire professionals, community representatives and emergency managers using focus groups and interviews. Results suggest that adaptive capacity is highly variable across the county and influenced by aspects such as community identity, strong communication networks and the local wood products industry. We contend that a better understanding of adaptive capacity to wildfire requires systematic documentation of how specific characteristics of local people interact to influence their ability to deal with change.

We studied gender, ethnicity, and environmental concern with an internet sample of Asian American women (n=157) and men (n=69), and European American women (n=222) and men (n=99). Participants completed the New Ecological Paradigm measure (NEP; Dunlap et al., 2000), the value bases of environmental concern (Schultz, 2000), and the Multigroup Ethnic Identity Measure-Revised (MEIM-R; Phinney & Ong, 2007). A 2 (ethnicity) x 2 (gender) ANOVA found no gender or ethnic differences on the NEP. A 2 (ethnicity) x 2 (gender) MANOVA with the three value bases as dependent variables found significant effects for ethnicity and gender Ethnic identification enhanced cultural influences on environmental concern. Findings are discussed in terms of the marketing of environmental sustainability to address climate change and other environmental risks.

In the first treatment, two 100-ha stands were thinned to reduce density while retaining old-growth structural characteristics, yielding residual stands with high structural diversity (HSD). Two other 100-ha plots were thinned to minimize old growth structure, producing even-aged stands of low structural diversity (LSD), and one 50-ha split-plot from each treatment was burned. In addition, two 50 ha old-growth Research Natural Areas (RNA) were selected as untreated reference plots, one of which was also burned. Fire treatments profoundly altered mite assemblages in the short term, and forest structure modification likely exacerbated that response. Sampling conducted two years following treatment confirmed a continuing decline in oribatid mite abundance. Oribatid species richness and assemblage heterogeneity also declined, and community dominance patterns were disrupted. Oribatid responses to fire were either more intense or began earlier in the LSD treatments, suggesting that removal of old-growth structure exacerbated mite responses to fire. Prostigmatids recovered quickly, but their populations nonetheless diminished significantly in burned split-plots. Mite assemblage responses to prescribed fire were continuing nearly two years later, with no clear evidence of recovery.

Carriere, in the Southern Appalachians SO FORESTS LA English DT Article DE Mycetophilidae; eastern hemlock; canopy arthropods; co-occurrence; vertical distribution ID NULL MODEL ANALYSIS; SPECIES COOCCURRENCE AB Over 400 species of insects have been found in association with eastern hemlock in the southern Appalachians. Eastern hemlock stands provide an ideal habitat for all life stages of mycetophilids. However, the diversity, distribution and co-occurrence patterns of these species throughout the tree canopy are unknown. This study was initiated to evaluate abundance, species richness and species composition within three designated strata in the canopy of eastern hemlock, assess species for vertical stratification patterns, and determine if co-occurrence patterns of mycetophilid species are random or non-random. During this study, 24 species representing 14 genera were identified and evaluated. Mycetophilid abundance, species richness and composition differed among the lower, middle, and upper strata. Unique assemblages were identified in each stratum, indicating vertical stratification. The upper stratum of the canopy had four exclusive species, the middle had six exclusive species, and the lower stratum had nine exclusive species. The co-occurrence pattern of mycetophilid species in the canopy of eastern hemlock was non-random.

Forest-based research on the species' silvicultural requirements and chestnut blight development are lacking. Pure American chestnut seedlings were planted in a two-age shelterwood forest with low residual basal area and in a midstory-removal treatment with high residual basal area. Survival did not differ between silvicultural treatments and averaged 67 percent across both treatments by the fifth year. Trees in the two-age shelterwood were 2.36 m and 16.8 mm larger in height and ground-line diameter, respectively, compared to trees in the midstory-removal by the fifth growing season. Blight occurrence was not affected by silvicultural treatment. Exploratory analyses indicated that seedling grading at planting and keeping trees free-to-grow through competition control would have resulted in a two-year gain in height and GLD growth in the two-age shelterwood treatment. The two-age shelterwood represented the most efficacious prescription for chestnut restoration, but the midstory-removal prescription may offer a reasonable alternative in areas where harvesting must be delayed.

We compiled and assessed the body of literature addressing fire effects on soils in Lake States forests to facilitate the re-measurement of previous studies for the development of new long-term datasets, and to identify existing gaps in the regional knowledge of fire effects on forest soils. Most studies reviewed addressed fire effects on chemical properties in pine-dominated forests, and long-term (>10 years) studies were limited. The major gaps in knowledge we identified include: (1) information on fire temperature and behavior information that would enhance interpretation of fire effects; (2) underrepresentation of the variety of forest types in the Lake States region; (3) information on nutrient fluxes and ecosystem processes; and (4) fire effects on soil organisms. Resolving these knowledge gaps via future research will provide for a more comprehensive understanding of fire effects in Lake States forest soils. Advancing the understanding of fire effects on soil processes and patterns in Lake States forests is critical for designing regionally appropriate long-term forest planning and management activities.

Growth responses to P fertilization are generally long-lasting in a wide range of soil types, but little is known about fertilization rates and long-term P cycling and availability. In 1982, exceptionally high P fertilization rates (0, 81, 162, and 324 kg P ha(-1)) were applied to a loamy Ultisol in central Louisiana, USA. We measured vegetation responses at age 27 years and sequentially extracted soil P to 1 m to elucidate potential P availability into the next rotation. Loblolly pine responded well to the lowest fertilization rate; total biomass was 39% greater in the fertilized plots compared to the unfertilized plots, but higher fertilization rates had no effect, presumably due to induced N-limitations. What little fertilizer P was found in the soils was in the moderately labile NaOH fraction in the surface 20 cm, and may be slowly available to the next pine rotation. Normal rates of P fertilizer will maintain elevated available P well into a second rotation in loamy Pleisteocene Ultisols of the western Gulf Coastal Plain. Exceptionally high rates were not effective at increasing potentially available P beyond normal rates. C1 [Scott, D. Andrew] US Forest Serv, Southern Res Stn, USDA, Normal, AL 35762 USA.

Forest management decisions, such as initial stand density, can promote climatic resiliency and moderate decreased productivity through the reduction of tree competition. The influences of climate (temperature and precipitation) and forest management (initial stand density) on the productivity of red pine (Pinus resinosa) across multiple sites within Huron National Forest, Michigan, were examined using dendrochronological methods. Two common planting regimes were compared in this analysis; low initial density (<988 trees per hectare) and high initial density (>1977 trees per hectare). Low initial density stands were found to have a higher climatic resilience by combining equal or greater measures of productivity, while having a reduced sensitivity to monthly and seasonal climate, particularly to summer drought.

PLANTATIONS; SOUTHERN UNITED-STATES; LOBLOLLY-PINE; COASTAL-PLAIN; SITE INDEX; GROWTH; MANAGEMENT; MORTALITY; EQUATIONS; SPAIN AB Longleaf pine (Pinus palustris Mill.) is an important tree species of the southeast U. S. Currently there is no comprehensive stand-level growth and yield model for the species. The model system described here estimates site index (SI) if dominant height (H-dom) and stand age are known (inversely, the model can project H-dom at any given age if SI is known). The survival (N) equation was dependent on stand age and H-dom, predicting greater mortality on stands with larger H-dom. The function that predicts stand basal area (BA) for unthinned stands was dependent on N and H-dom. For thinned stands BA was predicted with a competition index that was dependent on stand age. The function that best predicted stand stem volume (outside or inside bark) was dependent on BA and H-dom. All functions performed well for a wide range of stand ages and productivity, with coefficients of determination ranging between 0.946 (BA) and 0.998 (N). We also developed equations to estimate merchantable volume yield consisting of different combinations of threshold diameter at breast height and top diameter for longleaf pine stands. The equations presented in this study performed similarly or slightly better than other reported models to estimate future N, H-dom and BA. The system presented here provides important new tools for supporting future longleaf pine management and research.

For correct analysis, all of the publicly available sequences of the species were collected and compared with those obtained in this study. Species for which no consensus sequence could be identified were excluded from the phylogenetic analysis. The levels of 16S rRNA gene sequence similarity within the cluster ranged from 98.6 to 100% with a mean value of 99.6 +/- 0.3%, and those of the gyrB gene ranged from 93.6 to 99.9% with a mean value of 96.3 +/- 1.5%. The observed average nucleotide substitution rate of the gyrB gene was ten times higher than that of the 16S rRNA gene, showing a far higher degree of variation. Strains sharing 99.3% or more gyrB sequence similarity (corresponding to an evolutionary distance of 0.0073) always formed monophyletic groups in both trees. Through the combined analysis of the two genes, clear cases of synonymy could be identified and, according to the priority rule, the assertion of the status of Streptomyces setonii as a distinct species and the reclassification of Streptomyces fimicarius as a later synonym of S. setonii and Streptomyces albovinaceus as a later synonym of Streptomyces globisporus are proposed.

TI Diddensiella caesifluorescens gen. nov., sp nov., a riboflavin-producing yeast species of the family Trichomonascaceae SO INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY LA English DT Article ID CANDIDA; SUGIYAMAELLA; SEQUENCES; MEMBER AB Four strains of a novel heterothallic yeast species were isolated from rotten wood collected in or near the Pi lis Mountains in Hungary. The strains produced riboflavin in liquid culture. Analysis of gene sequences for the D1/D2 domains of the LSU nuclear rRNA, as well as analysis of concatenated gene sequences for the D1/D2 nuclear LSU rRNA, mitochondrial SSU rRNA and cytochrome oxidase II placed the novel species in a small clade including only two recognized species, Candida santjacobensis and Candida transvaalensis, in the family Trichomonascaceae. DNA sequence analyses demonstrated that the novel species was distinct from all currently recognized teleomorphic yeast genera. The name Diddensiella caesifluorescens gen nov., sp. nov. is proposed to accommodate the novel genus and species. The new genus proposed here can be recognized only from gene sequence analysis, because the characters of its asexual reproduction and ascospore formation are shared by several members of the genera Trichomonascus, Sugiyamaella and Spencermartinsiella. The type and isotype strains of D. caesifluorescens are NCAIM Y.01949(T) (=NRRL Y-48781(T)=CBS 12613(T)) and NCAIM Y.01956(T)(=NRRL Y-48782(T)=CBS 12614(T)), respectively. In view of their close relatedness to D. caesifluorescens, C. santjacobensis and C. transvaalensis are transferred to the genus Diddensiella as new combinations in accordance with changes in the International Code of Nomenclature for algae, fungi and plants.

Biosynthesis of aflatoxin involves the coordinated expression of more than 25 genes. The function of one gene in the aflatoxin gene cluster, aflJ, is not entirely understood but, because previous studies demonstrated a physical interaction between the Zn(2)Cys(6) transcription factor AflR and AflJ, AflJ was proposed to act as a transcriptional co-activator. Image analysis revealed that, in the absence of aflJ in A. parasiticus, endosomes cluster within cells and near septa. AflJ fused to yellow fluorescent protein complemented the mutation in A. parasiticus Delta flJ and localized mainly in endosomes. We found that AflJ co-localizes with AflR both in endosomes and in nuclei. Chromatin immunoprecipitation did not detect AflJ binding at known AflR DNA recognition sites suggesting that AflJ either does not bind to these sites or binds to them transiently. Based on these data, we hypothesize that AflJ assists in AflR transport to or from the nucleus, thus controlling the availability of AflR for transcriptional activation of aflatoxin biosynthesis cluster genes. AflJ may also assist in directing endosomes to the cytoplasmic membrane for aflatoxin export.

The SVCV is therefore listed as a notifiable pathogen by the International Organization for Animal Health. In June 2011, a significant mortality event of wild common carp Cyprinus carpio occurred in Minnehaha Creek near its confluence with Mississippi River Pool 2 in Minneapolis, Minnesota. Clinical signs of moribund fish included hemorrhagic lesions in the skin, eyes, and internal adipose tissue. The SVCV was isolated from pooled kidney and spleen of the fish. Rhabdovirus particles were seen upon examination of infected cell culture fluid by electron microscopy. The virus was confirmed to be SVCV subtype Ia by reverse transcription PCR and sequencing. This is the first report of SVCV within the state of Minnesota and the ninth documented case in North America. Received March 27, 2012; accepted July 2, 2012 C1 [Phelps, Nicholas B.

Here, we sought to further our understanding of cellular metabolism in fish by examining the metabolic responses of cell lines derived from channel catfish Ictalurus puntatus (CCO), white bass Morone chrysops (WBE), and fathead minnow Pimephales promelas (EPC) to both mitochondrial and thermal stressors. Using extracellular flux (EF) technology, we simultaneously measured the oxygen consumption rate (OCR; a measure of mitochondrial function) and extracellular acidification rate (ECAR; a surrogate of glycolysis) in each cell type. We performed a mitochondrial function protocol whereby compounds modulating different components of mitochondrial respiration were sequentially exposed to cells. This provided us with basal and maximal OCR, OCR linked to ATP production, OCR from ion movement across the mitochondrial inner membrane, the reserve capacity, and OCR independent of the electron transport chain. After heat shock, EPC and CCO significantly decreased OCR and all three cell lines modestly increased ECAR. After heat shock, the reserve capacity, the mitochondrial energetic reserve used to cope with stress and increased bioenergetic demand, was unaffected in EPC and CCO and completely abrogated in WBE. These findings provide proof-of-concept experimental data that further highlight the utility of fish cell lines as tools for modeling bioenergetics.

From the beginning, vessel operators in the eastern Gulf of Alaska have reported poor scallop adductor muscle quality characterized by tissue of stringy texture that tears easily during shucking. The Alaska scallop industry designates these scallops as "weak meats" and has difficulty marketing the product. Our research objective was to quantify variability in the quality of adductor muscle of Alaskan weathervane scallops. Physical measurements and chemical composition analyses were conducted for 2 groups of whole scallops from Yakutat (weak and standard) and 2 groups of scallop adductor muscles from Kodiak (Kodiak 1 and Kodiak 2). Moisture content was significantly higher (P<0.05) in weak than in standard adductor muscles. Glycogen content was similar (P>0.05) for standard, Kodiak 1, and Kodiak 2 adductor muscles, but was significantly lower (P < 0.05) in weak adductor muscles. Muscle condition indices were significantly lower (P<0.05) in weak than in standard adductor muscles. Results indicate that weak adductor muscle samples were lower in overall quality than the other 3 groups. Further investigation into the biological causes of weak adductor muscle in the eastern Gulf of Alaska scallops is warranted. C1 [Brenner, Kathryn; Oliveira, Alexandra C.

Viburnum tinus L. a commonly grown nursery plant, were infested with E. postvittana eggs, sprayed to run-off and mortality recorded. Several treatments were identified as equally efficacious as the standard chlorpyrifos spray (500 mu g/l). The insecticides that compared most favorably with chlorpyrifos were lambda-cyhalothrin and gamma-cyhalothrin. Four horticultural mineral oils demonstrated good ovicidal properties when evaluated alone versus when combined with reduced rates of the above insecticides or spinosad, imidacloprid or thiacloprid. The response of some insecticide and horticultural mineral oil combinations varied, suggesting that the oil selected may be important. Chlorpyrifos, lambda-cyhalothrin, gamma-cyhalothrin and spinosad provided similarly high levels of residual control of neonates for up to 10 d from application. Mixtures of UltraPure, an nC21 horticultural mineral oil, with reduced rates of the above insecticides maintained residual efficacy. Alternative treatments evaluated in this study may provide a high level of E. postvittana control through egg mortality and residual effects on emerging neonates over the hatching period. Field trials are required to verify the potential of these alternatives for commercial application. (C) 2012 Elsevier Ltd. All rights reserved.

TI Removal of molluscicidal bait pellets by earthworms and its impact on control of the gray field slug (Derocerus reticulatum Mueller) in western Oregon grass seed fields SO CROP PROTECTION LA English DT Article DE Crop residues; Grass seed production; Lumbricus terrestris ID RESIDUE MANAGEMENT; TILLAGE SYSTEMS; IRON PHOSPHATE; METALDEHYDE; POPULATIONS; ABUNDANCE; SOILS AB Slugs are common pests of grass seed fields in western Oregon and the current focus of repeated, and often unsuccessful, efforts by growers to control them using molluscicides. Here we document rapid loss of molluscicidal bait pellets to earthworms and the resulting adverse effects on slug control. Three years of field studies were conducted at 17 locations with contrasting crops, soil types, residue levels, and tillage management programs. Baits were isolated in covered, sunken, open bottom arenas in the field to exclude removal by slugs, rodents, or birds. Forty hours of nighttime field observations and photographic documentation were collected to support the hypothesis that earthworms were removing slug bait before it had the opportunity to kill slugs. Greenhouse studies were conducted on the gray field slug (Derocerus reticula turn Mueller), in screen-topped arenas to determine the effects on mortality, seedling survival, and egg fecundity in a bait-depleting environment. Field data showed that an average of 17% of all bait pellet types were removed nightly by earthworms, with a range of 5.1-6.4 days until 100% disappearance. Individual earthworms in the field were observed removing up to three bait pellets per hour. Earthworms removed a 5% metaldehyde formulation significantly faster than either 4% metaldehyde or 1% iron phosphate pellet baits, possibly because of the smaller physical pellet size. Seedling survival in the greenhouse >= 65% was achieved by the highest rate of 4% metaldehyde bait pellets, the two highest rates of 7.5% metaldehyde granules, and the two highest rates of 25% metaldehyde liquid formulation. Earthworms showed no behavioral interest in the granular or liquid formulations, providing growers with attractive alternatives to the ineffectual pelleted baits currently in widespread use.

Fungicides are the only practical control method, but a guideline for timing of fungicides is not available. Typically, producers apply fungicides in July based on past experiences such as when frequent afternoon rains are forecast, or after severe blight symptoms develop. The objective of the study was to evaluate fungicide timing criteria, including a calendar schedule, and disease incidence and decision-based weather thresholds. Experiments with a randomized complete block design were performed at a site in AL and MS for three years. For 2009, 2010, treatments included a non-treated control and five treatments where fungicide timing was based on a calendar schedule, three disease threshold criteria and a rain frequency criterion. In 2011, treatments included a non-treated control, a calendar schedule, and two disease threshold criteria. The calendar schedule was the only timing treatment that resulted in significantly less blight incidence than the control in all experiments. Fungicide application based on the lowest disease threshold (16-30 blight leaves per plant quadrant) and the rain frequency criteria (>3 rain events of >6.3 mm rain within the previous seven days) suppressed blight development equal to the calendar schedule in three experiments and all other criteria provided equal disease suppression in at least one experiment. While not tested in combination, the recommendation is to schedule fungicide applications based on calendar-dates (the most consistently reliable criterion), and use the disease threshold of >16 blighted leaves per plant quadrant (a moderately reliable criterion) to adjust timing within 1-2 weeks of the calendar-date in response to year-to-year differences in disease pressure, which can vary due to weather variables such as rainfall frequency (a moderately reliable criterion).

TI High Prevalence of Toxoplasma gondii Antibodies in Domestic Pigs in Oaxaca State, Mexico SO JOURNAL OF PARASITOLOGY LA English DT Article ID INFECTION; SEROEPIDEMIOLOGY; DURANGO AB Pigs are important in the epidemiology of toxoplasmosis in North America. Seroprevalence of Toxoplasma gondii infection in 525 domestic pigs (337 backyard raised, 188 farm raised) in Oaxaca State, Mexico was determined using the modified agglutination test (MAT, cutoff 1:25). Antibodies to T. goudii were found in 58 (17.2%) of the 337 backyard pigs with MAT titers of 1:25 in 10, 1:50 in 12, 1:100 in 18, 1:200 in 6, 1:400 in 6, 1:800 in 3, and 1:1,600 in 3. Seropositive pigs were found in 39 (37.9%) of 103 homes in all 7 municipalities surveyed. Seroprevalence of T. gondii infection in backyard pigs varied with age, gender, geographic region, climate, and altitude. High seroprevalence was found in pigs >= 9-mo-old (40%), in females (40%), in pigs from the Istmo region (33.3%), and in those raised in a tropical climate (65%). Seroprevalence was higher (24.5%) in pigs raised at 100-660 m above sea level than in those at 20-60 m of altitude (14.2%). With respect to farm pigs, only 1 (0.5%, MAT titer 1:100) of 188 pigs from 5 farms was positive for anti-T. gondii antibodies. The results affirm that the management system (outdoor vs. indoor system with biosecurity) is a key factor in the epidemiology of porcine toxoplasmosis. Because there is no national system of determining the T. gondii infection status at the time of slaughter, precautions should be taken while handling pig carcasses, and all pork should be cooked thoroughly before human consumption.

TI Analysis of Giardin Expression During Encystation of Giardia lamblia SO JOURNAL OF PARASITOLOGY LA English DT Article ID DIFFERENTIATION; GENES; MECHANISMS; CYSTS; TROPHOZOITES; INVITRO; BIOLOGY; CYCLE AB The present study analyzed giardin transcription in trophozoites and cysts during encystation of Giardia lamblia. Encystment was induced using standard methods, and the numbers of trophozoites and cysts were counted at various time points during the process. At all time points, RNA from both stages were assayed for levels of alpha2-, beta-, and delta-giardin mRNA as well as for cyst wall protein 3 (CWP3) mRNA using quantitative RT-PCR. In encystation medium, the number of G. lamblia trophozoites decreased, while the number of cysts increased between 0 and 72 hr. In trophozoites, alpha2- and beta-giardin transcription decreased over time, while delta-giardin transcription remained unchanged during the same time period. CWP3 transcription exhibited a slight increase in trophozoites at 8 hr, followed by a decrease at subsequent time points. Expression of alpha2-giardin increased at 48 hr in cysts followed by decreased expression at 72 hr, while beta- and delta-giardin expression was unchanged during encystation. CWP3 transcription gradually decreased from 24-72 hr in cysts. Consistent with previous studies, giardin proteins appeared to be disassembled into amorphous structures inside cysts during encystation. These findings represent the first analysis of giardin transcription in separate populations of trophozoites and cysts during encystation and indicate differential regulation of giardin mRNA expression by these developmental stages.

Scott TI Comparison of Cotton Square and Boll Damage and Resulting Lint and Seed Loss Caused by Verde Plant Bug, Creontiades signatus SO SOUTHWESTERN ENTOMOLOGIST LA English DT Article ID HETEROPTERA; HEMIPTERA; MIRIDAE; PENTATOMIDAE AB Retention of cotton, Gossypium hirsutum L., bolls and squares (referred to as fruit retention), boll damage, and resulting lint and seed weight loss were assessed when two (2010) and three (2011) age classes of sympodial fruiting branches with different ages of squares and bolls where exposed to verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), in cages in the field. An increasing trend was observed in fruit retention from the youngest to the oldest branch age treatment for both years, and the effect was primarily determined by the age of the fruiting body. Low fruit retention (<20%) was seen in young bolls <7 days old in the first two fruiting positions from the main stem compared with >80% retention in checks not exposed to verde plant bug. In infested cages, fruit retention of young bolls was significantly less (P = 0.016) than older bolls and squares 2-3 days before bloom or younger. Similar to fruit retention results, damage of harvested bolls and lint and seed weight (using zero for abscised fruit) differed among the age of the fruiting body primarily for fruiting positions one (2010 and 2011) and two (2011) (P < 0.0001). The first two fruiting positions were the main contributors to plant productivity differences in lint and seed weight. Overall, verde plant bugs given a feeding choice reduced fruit retention in young bolls <7 days old, damaged retained bolls <11 days old, and larger bolls and young squares at least 2-3 days from bloom incurred significantly less abscission and damage. These results supported the interpretation that less fruit retention and more damage of young bolls justified a focus on protecting young bolls in a pest management program, especially during early to peak bloom when young bolls are abundant.

TI Disinfestation of Beauveria bassiana from Adult Lygus hesperus Using Ultraviolet-C Radiation SO SOUTHWESTERN ENTOMOLOGIST LA English DT Article ID HEMIPTERA-MIRIDAE; TEMPERATURE AB The western tarnished plant bug, Lygus hesperus Knight, is an important pest of crops in the western U.S. Research on the biology of L. hesperus often relies on access to healthy insects from laboratory cultures. However, maintenance of colony vigor often requires periodic introductions of field-collected specimens or re-initiation of the colony. Either approach poses a risk of introducing diseases with the field-collected insects. We examined the potential Utility of exposure to ultraviolet light (UV-C) as a way to sterilize adult L. hesperus previously treated with spores of Beauveria bassiana (Balsamo) Vuillemin, and also examined the influence of exposure to UV-C on subsequent reproduction by lygus. Mortality of B. bassiana conidia increased rapidly with increased exposure to UV irradiation, which also delayed germination of conidia at exposure times >= 2 minutes. Based on assays 48 hours after exposure to UV, 6.45 minutes of exposure to UV-C (approximate to 130 mu W cm(-2)) reduced germination of conidia to approximately 1%. When L. hesperus adults treated with B. bassiana were exposed to UV-C for 2 hours, infection by the pathogen was greatly decreased but not eliminated. Similar exposure of untreated L. hesperus adults did not reduce subsequent fecundity. Our results suggest that routine exposure of field-collected adults to UV-C irradiation may reduce the probability of introducing B. bassiana into laboratory colonies with little or no adverse reproductive consequences.

TI Toxicity to Adult Brown Stink Bug (Hemiptera: Pentatomidae) in a Glass-Vial Bioassay of Selected Insecticide Mixtures SO SOUTHWESTERN ENTOMOLOGIST LA English DT Article ID COTTON; HETEROPTERA; GREEN; MIRIDAE; INJURY; DAMAGE; TEXAS AB Recently, the brown stink bug, Euschistus servus (Say), has become the dominant species in the stink bug complex on cotton, Gossypium hirsutum L., in Central Texas. Options to control the insect depend mostly on and are limited to the use of insecticide. Data are needed to determine the toxicity of currently available insecticides to brown stink bug and develop baseline mortality to assess resistance to insecticides in Central Texas. Using a glass-vial bioassay, the LC10 and LC50 values for selected commercially formulated insecticides, the technical-grade active ingredients, and mixtures of active ingredients were determined for brown stink bugs captured in black-light traps near farmlands in Caldwell County, Texas. The LC10 and LC50 values showed the mixtures of technical-grade insecticides were 37- to 526- and 58- to 384-fold, respectively, more toxic to brown stink bug compared to the respective commercial formulations. The toxicological response of the technical-grade active ingredients relative to the mixtures varied from synergistic to antagonistic. Baseline data for brown stink bug mortality are useful for comparison with local populations should suspicion of tolerance to the insecticides develop in Central Texas. Data demonstrate lack of potentiation of the mixtures, probably because of absence of additivity or synergism in the composition of active and inert ingredients in the formulations or decreased composition of each component in the formulated mixtures.

TI Foraging by Hippodamia convergens for the Aphid Sitobion avenae on Wheat Plants Growing in Greenhouse Plots SO SOUTHWESTERN ENTOMOLOGIST LA English DT Article ID GREENBUGS HOMOPTERA; INDIGENOUS COCCINELLIDS; SORGHUM AB We investigated predation by adult convergent lady beetle, Hippodamia convergens Guerin-Meneville, on English grain aphid, Sitobion avenae L., on wheat, Triticum aestivum L., growing in 1.8 x 1.8 m plantings in a greenhouse with a soil floor. The wheat was planted to simulate a typical production field, with one seed per 2.5 cm in each row, and rows planted 15.2 cm apart. The plot was artificially infested with aphids. Beetles in one group (designated "light-fed") were provided with 20 English grain aphids of mixed instars per day, whereas beetles in a second group (designated "heavy-fed") were provided with 80 English grain aphids per day for 4-6 days before observation. Beetles were observed foraging in the plot for a period of 12 minutes. For each visit to plants, and for movements of beetles on the soil floor of the plot, the amount of time spent searching and eating were recorded, as were incidents of beetle flight from one location to another in the plot or out of the plot. Air temperature, intensity of solar radiation, height of the wheat plants, and density of the aphids were measured concomitant with foraging observations. The number of aphids eaten in the wheat plots averaged 0.16 per minute. The number of aphids eaten per minute increased as the number of aphids per tiller increased (t = 3.80; df = 1, 46; P = 0.0004). Analysis of covariance applied to predation data from the aphid-infested plots indicated that light-fed beetles ate a significantly greater number of aphids per minute than did heavy-fed beetles (F = 5.35; df = 1, 212; P = 0.02). However, the number of aphids per tiller, the covariable in the analysis, was not significant (F = 1.64; df = 1, 211; P = 0.20), indicating that predation rate was not reldted to aphid density. This observation suggested that the physiological state of the beetles (poorly fed or well fed) was dominant over aphid density in influencing predation rate.

A downdraft gasifier is performed for syngas production in Mississippi State. The syngas from the gasifier contains up to 49% (vol) N-2. High-level nitrogen-containing (nitrogen can be up to 60%) synthesis gas is converted to liquid hydrocarbon mixture through a one-stage catalytic process with a Fe-Pd/ZSM-5 catalyst. The Fe-Pd/ZSM-5 catalyst shows relatively high activity and selectivity in producing liquid hydrocarbons when running with nitrogen-rich syngas. The CO conversion, hydrocarbon selectivity and hydrocarbon distribution as a function of temperature, pressure, GHSV, composition of the feed, and reaction time are examined. (C) 2012 Elsevier Ltd.

TI Agrilus auroguttatus exit hole distributions on Quercus agrifolia boles and a sampling method to estimate their density on individual trees SO CANADIAN ENTOMOLOGIST LA English DT Article ID GOLDSPOTTED OAK BORER; SCHAEFFER COLEOPTERA BUPRESTIDAE; BRONZE BIRCH BORER; UNITED-STATES; SOUTHERN CALIFORNIA; COXALIS WATERHOUSE; CERAMBYCIDAE; POPULATIONS; WASHINGTON; WOODLANDS AB In recent decades, invasive phloem and wood borers have become important pests in North America. To aid tree sampling and survey efforts for the newly introduced goldspotted oak borer, Agrilus auroguttatus Schaeffer (Coleoptera: Buprestidae), we examined spatial patterns of exit holes on the boles (trunks) of 58 coast live oak, Quercus agrifolia Nee (Fagaceae), trees at five sites in San Diego County, southern California, United States of America. Agrilus auroguttatus exit hole densities were greater at the root collar than at mid-boles (6.1 m above ground). Dispersion patterns of exit holes on lower boles (<= 1.52 m) were random for trees with low exit hole densities and aggregated for trees with high exit hole densities. The mean exit hole density measured from three randomly chosen quadrats (0.09 m(2)) provided a statistically reliable estimate of the true mean exit hole density on the lower bole, with <25% error from the true mean. For future sampling and survey efforts in southern California oak forests and woodlands, exit hole counts within a 0.09 m(2) quadrat could be made at any three locations on lower Q. agrifolia boles to accurately estimate A. auroguttatus exit hole densities at the individual tree level.

Leuconostoc mesenteroides (LM), Bacillus atrophaeus (BA) or Pseudomonas aeruginosa (PA) aliquots were exposed on nutrient agar plates to Array 1 (AR1, 0.2 mW cm(-2)) or Array 2 (AR2, 80 mW cm(-2)), which emitted impure or pure blue light (0-300 J cm(-2)), respectively. Inoculated control (room light only) plates were incubated (48 h) and colonies enumerated. The antifungal properties of blue light combined with ERY (11.4 and 22.8 mu mol l(-1)) on Penicillium digitatum (PD) and Fusarium graminearum (FG) conidia were determined. Conidial controls consisted of: no light, room light-treated conidia and ERY plus room light. Light-treated (ERY + blue light) conidial samples were exposed only to AR2 (0-100 J cm(-2)), aliquots spread on potato dextrose agar plates, incubated (48 h, 30 degrees C) and colonies counted. Blue light alone significantly reduced bacterial and FG viability. Combined with ERY, it significantly reduced PD viability. Blue light is lethal to bacteria and filamentous fungi although effectiveness is dependent on light purity, energy levels and microbial genus. C1 [De Lucca, A. J.; Carter-Wientjes, C.; Williams, K.

TI Homologous RXLR effectors from Hyaloperonospora arabidopsidis and Phytophthora sojae suppress immunity in distantly related plants SO PLANT JOURNAL LA English DT Article DE Arabiopsis thaliana; Hyaloperonospora arabidopsis; Phytophthora sojae; effector; oomycete; Nicotiana benthamiana; resistance; pathogenesis ID PROGRAMMED CELL-DEATH; DOWNY MILDEW; DISEASE RESISTANCE; SEQUENCE POLYMORPHISMS; NICOTIANA-BENTHAMIANA; PATHOGEN INTERACTIONS; MODEL OOMYCETE; INFESTANS; AVIRULENCE; THALIANA AB Diverse pathogens secrete effector proteins into plant cells to manipulate host cellular processes. Oomycete pathogens contain large complements of predicted effector genes defined by an RXLR host cell entry motif. The genome of Hyaloperonospora arabidopsidis (Hpa, downy mildew of Arabidopsis) contains at least 134 candidate RXLR effector genes. Only a small subset of these genes is conserved in related oomycetes from the Phytophthora genus. Here, we describe a comparative functional characterization of the Hpa RXLR effector gene HaRxL96 and a homologous gene, PsAvh163, from the Glycine max (soybean) pathogen Phytophthora sojae. HaRxL96 and PsAvh163 are induced during the early stages of infection and carry a functional RXLR motif that is sufficient for protein uptake into plant cells. Both effectors can suppress immune responses in soybean. HaRxL96 suppresses immunity in Nicotiana benthamiana, whereas PsAvh163 induces an HR-like cell death response in Nicotiana that is dependent on RAR1 and Hsp90.1. Transgenic Arabidopsis plants expressing HaRxL96 or PsAvh163 exhibit elevated susceptibility to virulent and avirulent Hpa, as well as decreased callose deposition in response to non-pathogenic Pseudomonas syringae. Both effectors interfere with defense marker gene induction, but do not affect salicylic acid biosynthesis. Together, these experiments demonstrate that evolutionarily conserved effectors from different oomycete species can suppress immunity in plant species that are divergent from the source pathogen's host.

A sister-group contrast to reveal the metabolic basis of DT was conducted between a desiccation-tolerant species, Selaginella lepidophylla, and a desiccation-sensitive species, Selaginella moellendorffii, at 100% relative water content (RWC) and 50% RWC using non-biased, global metabolomics profiling technology, based on GC/MS and UHLC/MS/MS2 platforms. A total of 301 metabolites, including 170 named (56.5%) and 131 (43.5%) unnamed compounds, were characterized across both species. S. lepidophylla retained significantly higher abundances of sucrose, mono-and polysaccharides, and sugar alcohols than did S. moellendorffii. Aromatic amino acids, the well-known osmoprotectant betaine and flavonoids were also more abundant in S. lepidophylla. Notably, levels of c-glutamyl amino acid, linked with glutathione metabolism in the detoxification of reactive oxygen species, and with possible nitrogen remobilization following rehydration, were markedly higher in S. lepidophylla. Markers for lipoxygenase activity were also greater in S. lepidophylla, especially at 50% RWC. S. moellendorffii contained more than twice the number of unnamed compounds, with only a slightly greater abundance than in S. lepidophylla. In contrast, S. lepidophylla contained 14 unnamed compounds of fivefold or greater abundance than in S. moellendorffii, suggesting that these compounds might play critical roles in DT. Overall, S. lepidophylla appears poised to tolerate desiccation in a constitutive manner using a wide range of metabolites with some inducible components, whereas S. moellendorffii mounts only limited metabolic responses to dehydration stress.

In this study, field moist and air-dried soils sampled from subarctic Alaska under three land use managements (i.e., forest, agriculture, and grassland converted from agricultural use and under a Conservation Reserve Program [CRP]) were extracted with deionized water and separated by filtration into different size fractions (2.5 mu m, 0.45 mu m, and 1 kDa). Water-soluble organic C (WSOC), water-soluble organic N, and fluorescence spectroscopy of each fraction were determined. There were few differences in quantitative data between samples from different land uses with air-dried samples, implying that air-dried samples were not suitable for characterizing the impact of soil management practices on soil WSOM. For field moist soil samples, the WSOC contents decreased in the order forest > CRP > agricultural land. Furthermore, WSOC was dominated by large (>0.45 mu m) and small (<1 kDa) size molecules in CRP and forest soils, whereas small molecules predominated in agricultural soils. The WSOM of different size fractions and land use displayed three similar fluorophore components (two humic-like and a tyrosine-like), indicating that the impact of land use was mainly on the quantity, rather than on the composition, of WSOM. In conclusion, our data suggested that the long-term agricultural land use could lower the WSOM levels in soils; however, the decreasing trend could be reversed by conversion of agricultural land to grassland under conservation.

It is estimated that RSV infections result in more than 100,000 deaths annually worldwide. Bovine RSV is a cause of enzootic pneumonia in young dairy calves and summer pneumonia in nursing beef calves. Furthermore, bovine RSV plays a significant role in bovine respiratory disease complex, the most prevalent cause of morbidity and mortality among feedlot cattle. Infection of calves with bovine RSV shares features in common with RSV infection in children, such as an age-dependent susceptibility. In addition, comparable microscopic lesions consisting of bronchiolar neutrophilic infiltrates, epithelial cell necrosis, and syncytial cell formation are observed. Further, our studies have shown an upregulation of pro-inflammatory mediators in RSV-infected calves, including IL-12p40 and CXCL8 (IL-8). This finding is consistent with increased levels of IL-8 observed in children with RSV bronchiolitis. Since rodents lack IL-8, neonatal calves can be useful for studies of IL-8 regulation in response to RSV infection. We have recently found that vitamin D in milk replacer diets can be manipulated to produce calves differing in circulating 25-hydroxyvitamin D-3. The results to date indicate that although the vitamin D intracrine pathway is activated during RSV infection, pro-inflammatory mediators frequently inhibited by the vitamin D intacrine pathway in vitro are, in fact, upregulated or unaffected in lungs of infected calves. This review will summarize available data that provide parallels between bovine RSV infection in neonatal calves and human RSV in infants.

While GD causes significant morbidity, mortality, and economic loss to the poultry industry, the fundamental mechanisms underlying this host-pathogen interaction are relatively unknown. This study used comparative global gene expression microarray analysis of GD-affected and clinically healthy chickens from a recent GD outbreak to glean insights into the molecular and cellular changes associated with this disease process. Histopathologic and immunohistochemical analyses confirmed extensive muscle damage and prominent leukocyte infiltration in the skin of GD-affected birds but not in healthy controls. The levels of mRNAs in the skin and underlying muscle corresponding to 952 microarray elements were altered in GD-afflicted birds compared with healthy controls, with 468 being increased and 484 decreased. From these, a subset of 386 genes was identified and used for biologic function and pathway analyses. The biologic functions that were most significantly associated with the differentially expressed genes were "inflammatory response" and "cellular growth and proliferation" classified under the categories of "disease and disorders" and "molecular and cellular functions," respectively. The biologic pathway that was most significantly associated with the differentially expressed genes was the nuclear factor-erythroid 2-related factor 2 (NRF2)-mediated oxidative stress pathway. Finally, in vitro infection of chicken macrophages with CS or CP modified the levels of mRNAs encoding interferon (IFN)-alpha, IFN-gamma, interleukin (IL)-1 beta, IL-6, IL-12p40, tumor necrosis factor superfamily 15 (downregulated), IL-8, and IL-10 (upregulated), thus confirming the suppressive effect of GD on the chicken immune system.

In this study we evaluated the potential of entomopathogenic nematodes to control two important ornamental pests: 1) Corythucha ciliata (Say) (Hemiptera: Tingidae), a native lace bug that attacks the foliage of sycamore trees, and 2) the recently described exotic pest, Stethobaris nemesis (Coleoptera: Curculionidae), a weevil that attacks amaryllis leaves and bulbs. In the laboratory, the virulence of six entomopathogenic nematode strains (comprising five species) was evaluated on sycamore leaf discs for potential to control C. ciliata, and four nematode species were evaluated for control of S. nemesis. Heterorhabditis indica (HOM1) exhibited higher virulence to C. ciliata than H. bacteriophora (Baine and Oswego strains), H. georgiana (Kesha), and Steinernema riobrave (355); S. carpocapsae (All) virulence was not statistically separated from the other nematodes with the exception of H. bacteriophora (Oswego) (which exhibited the lowest virulence). Additionally, among the six nematodes tested, H. indica (HOM1) produced the highest level of infective juveniles in C. ciliata. Steinernema carpocapsae (All) exhibited the highest virulence to control S. nemesis (in well-plates containing soil), yet both S. carpocapsae (All) and S. feltiae (SN) exhibited high virulence after only id post-treatment. The other nematodes tested for S. nemesis suppression, H. bacteriophora (Hb) and H. indica (HOM1), also showed high levels of virulence particularly at 3 d post-treatment. Our results indicate that several entomopathogenic nematodes offer potential for control of C. ciliata and S. nemesis and thus additional research, e.g., field studies, is warranted.

Life cycle, reproductive and population parameters of R. nu and C. includens reared on artificial diet were determined under controlled environmental conditions. Fecundity increased from d 2 to 3 with values of 67.6 eggs per female for R. nu and 75.7 eggs for C. includens. An average of 79.9% (R. nu) and 74.4% (C. includens) of individuals reached the larval stage and 71.1% (R. nu) and 71.4% (C. includens) of individuals reached the adult stage. The life expectancy (ex) curve showed 4 and 3 periods of mortality. The survivorship curves of the 2 species resembled the theoretical type I. Life table analysis determined that R. nu and C. includens have the potential to quickly increase their populations under controlled rearing conditions. These results provide important information that will be used to improve artificial rearing procedures contributing with biological studies towards to develop management programs of both species.

Sw. and Costus spiralis (Jacq.) Roscoe var. spiralis (Costaceae) are economically important plants due to their pharmacological and medicinal properties and ornamental value. These plants are natives from the Brazilian Atlantic Rainforest and are fed upon by Agaraea minuta Schaus, 1892 (Lepidoptera: Arctiidae). This study describes the damage done by A. minuta on C. spicatus and C. spiralis and the biological and ecological aspects of parasitism of A. minuta by Diolcogaster sp. (Hymenoptera: Braconidae). Twenty stems of C. spicatus and C. spiralis with 100 last-instar caterpillars of A. minuta, were collected per plant in each of 2 years. The stem heights (F, P > 0.05), leaf lengths (F, P > 0.05), leaf widths (F, P > 0.05) and the number of leaves per stem (F, P > 0.05) of both plant species; number of pupae obtained from caterpillars of A. minuta (F, P > 0.05), adult emergence of this defoliator (F, P > 0.05) and of Diolcogaster sp. (F, P > 0.05) were similar during the 2 study periods. Agaraea minuta fed on C. spicatus and C. spiralis, and Diolcogaster sp. was shown to be a parasitoid suppressor of populations of this defoliator.

TI ACOUSTICAL DETECTION OF EARLY INSTAR RHYNCHOPHORUS FERRUGINEUS (COLEOPTERA: CURCULIONIDAE) IN CANARY ISLAND DATE PALM, PHOENIX CANARIENSIS (ARECALES: ARECACEAE) SO FLORIDA ENTOMOLOGIST LA English DT Article DE red palm weevil; invasive species; pest management; Caribbean ID WEEVIL; MANAGEMENT; PATTERNS; CURACAO; LARVAE AB The red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier), recently found in Curacao and Aruba, has become an economically significant palm tree pest in many tropical and subtropical regions. By the time a palm infested with RPW displays visible damage, larvae have destroyed much of the trunk internal structure, typically resulting in tree mortality. Acoustic technology may enable pest managers to detect and treat early RPW infestations before tree mortality, and to reduce unwanted importation and/or exportation of infested palms. Experiments were conducted in Aruba to determine the detectability of sounds produced by early instars in open, urban environments and in enclosures with ca. 10 dB acoustical shielding. To distinguish RPW signals from background noise, recordings first were analyzed to identify larval sound impulse bursts, trains of 7-199 impulses, 3-30-ms in duration, where impulses within the train were separated by less than 0.25 s. For a burst to be considered a larval sound, it was specified that a majority of its impulses must have spectra that match mean spectra (profiles) of known larval sound impulses more closely than profiles of background noise or known nontargeted sound sources. Based on these analyses, RPW larval bursts were detected in >80% of palm fronds inoculated with neonates the previous day. There were no significant differences between burst rates in enclosed and open environments, but the shielding provided by the enclosure enabled detection of early instars from greater distances. Thus, there is potential to use acoustic technology to detect early RPW infestation in either minimally shielded or open environments. In addition, because late-instar impulses ranged to higher amplitude and had greater diversity of spectral features than with early instars, it may be possible to identify late-instar infestations based on the amplitudes and the diversity of sound features detected.

To improve the current monitoring and survey techniques of X. glabratus, various trapping and flight behavior studies were conducted in natural areas with host species in Alachua County, Florida. Daylight flight rhythm studied at Austin Cary Memorial Forest twice in Sep 2010 using sticky traps baited with manuka lures showed that X. glabratus flies mostly between 1600 and 1800 h daylight saving time. Flight height of the beetle was determined in a trapping study using ladder-like traps. The largest number of beetles was trapped at heights of 35-100 cm above the ground. Seasonality of X. glabratus was studied in Florida from Mar 2010-Dec 2011. Three peaks of trap catches occurred during Apr 2010, Oct 2010 and Mar 2011. To find the optimal Lindgren funnel trap design for X. glabratus, a study was conducted using 4, 8, 12 and 16 funnels per trap. Funnel traps with 8, 12, 16 funnels per trap captured similar numbers of X. glabratus, but significantly more than with 4 funnels per trap. The effect of aging of manuka lures was studied at 2 different sites in Alachua County, Florida. New manuka lures trapped significantly more X. glabratus than lures aged 2, 4 and 6 wk. Trap color, whether black, white, blue, yellow, red or transparent, had no significant influence on the number of X. glabratus trapped.

Adults feed on fruit juices and these could be sources of attractive compounds. While orange juice (Citrus sinensis L.) is nutritious, guava juice (Psidium guajaua L.) is toxic. The behavioral responses to the two juices and the juices' volatiles were examined in two species ancestrally sympatric with guava (Doryctobracon areolatus [Szepligeti] and Utetes anastrephae [Viereck]) and a species exotic to guava's neotropical region of origin (Diachasmimorpha longicaudata [Ashmead]). It was predicted that males of the sympatric species, with an evolutionary opportunity to recognize and avoid guava, would neither feed on nor respond to guava volatiles. Females of the syrnpatric species were predicted to avoid feeding upon guava while responding to volatiles in the context of searching for oviposition sites. Males and females of the exotic species were predicted to feed upon and respond to both guava and orange. Orange was universally fed upon and its volatiles were found to be attractive. None of the males, including the exotic species', occupied guava feeding-stations in no-choice situations, but male U. anastrephae responded to guava volatiles. Against expectations, female D. areolatus occupied guava feeding stations. In general, responses to orange were stronger and more universal than those to guava. The preference differences the various species showed between guava and orange are a step forward in identifying the chemical basis of fruit-attractiveness. They provide 1) further evidence that not all uninfested fruit are equally attractive and 2) a relatively attractive and easily obtainable standard, orange, with which to compare the attractiveness of other fruit in the future.

TI REARING THE OLIGOPHAGOUS CACTOBLASTIS CACTORUM (LEPIDOPTERA: PYRALIDAE) ON MERIDIC DIETS WITHOUT HOST PLANT MATERIALS SO FLORIDA ENTOMOLOGIST LA English DT Article DE Cactoblastis; Opuntia; artificial diet; mass rearing ID ARTIFICIAL DIET; BODY-SIZE; NORTH-AMERICA; OPUNTIA; TEMPERATURES; MANAGEMENT; FECUNDITY; IMPACT; MEXICO AB Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), an oligophagous Opuntia spp. herbivore from South America, has been used successfully as a biological control agent for several invasive Opuntia species around the world. However, its unintentional arrival in Florida raised serious concern over its possible effect on native Opuntia biodiversity and Opuntia-based industries. Development of control tactics to mitigate the threat of this invasive pest to North America relied upon a constant supply of all life stages of this insect species. Therefore, 3 strains of C. cactorum were established in a laboratory insectary and trials were initiated to optimize rearing methods using an artificial diet. Because monophagous or oligophagous lepidopterans may be sensitive to the balance of nutrients and/or the presence of specific feeding cues and because different strains of an oligophagous lepidopteran may respond differently to various meridic diets, we compared the development and survival of 3 strains of C. cactorum on several meridic diets without host plant materials. Although C. cactorum is an oligophage within the genus Opuntia, it accepted and developed on several diets containing non-host plant ingredients, yeast, and fish meal. The source and balance of non-host nutrients significantly affected all reproductive parameters of C. cactorum. The best performance of C. cactorum was on diets that contained white kidney beans, brewer's yeast, wheat germ and/or soybeans. C1 [Carpenter, James E.] ARS, USDA, CPMRU, Tifton, GA 31793 USA.

Since its unintentional arrival to the United States in 1989 and to Mexican islands in 2006, it has become a serious threat to the diversity of both wild and cultivated species of Opuntia Mill. in North America. The native ecological host range of C. cactorum has not been directly ascertained and host acceptance is unclear. Taxonomic nomenclature of Opuntia spp. has been confusing, contradictory, and rapidly changing, leading to inaccurate conclusions about host plant use by C. cactorum in its native South American range. This study was conducted to better understand the biology and ecology of C. cactorum in Argentina by evaluating, under laboratory conditions, the insects' performance (survivorship, development time, potential fecundity) on 8 Opuntia spp. occurring in Argentina. Feeding trials were conducted on 5 Opuntia spp. native to Argentina and 3 Opuntia spp. native to Mexico. Cactoblastis cactorum larvae failed to feed on 2 native Opuntia spp., and had their greatest performance on the North American O. ficus-indica (L). Mill. and O. robusta H. L. Wendl. ex Pfeiff., and the South American O. arechaualetae Speg. Because the insects for the experiments were originally collected on O. ficus-indica, a reciprocal cross feeding experiment with insects collected on O. megapotamica Arechav. was also conducted to test for a potential host plant-mediated local adaptation effect. Some evidence for host plant adaptation was detected in populations collected on the South American host, O. megapotamica. Local adaptation, as documented here, could have consequences for the invasion process of C. cactorum in North America.

TI ASSESSING THE USEFULNESS OF DNA BARCODING TO IDENTIFY OXYCARENUS HYALINIPENNIS (HEMIPTERA: OXYCARENIDAE) IN FLORIDA, A POTENTIALLY INVASIVE PEST OF COTTON SO FLORIDA ENTOMOLOGIST LA English DT Article DE mitochondrial DNA; Cytochrome-C oxidase subunit I; haplotype; cotton seed bug; Oxycarenus ID SEQUENCES; IDENTIFICATION; POLYMORPHISM; HETEROPTERA; LYGAEIDAE; ARMYWORM; PRIMERS; DIPTERA AB Invasive insects present an ongoing challenge to the safety of U.S. agriculture. A current threat to the U.S. cotton industry is Oxycarenus hyalinipennis (Costa), commonly known as the cotton seed bug. Populations are found throughout most of the world except for North America, and the southeastern U.S. is believed to provide a favorable environment for its establishment. A major component in efforts to control the spread of invasive pests is the rapid and accurate identification of intercepted specimens. Unfortunately, O. hyalinipennis belongs to an incompletely characterized taxon where the assignment of species identity by simple morphological keys is often problematic. In this study, we assessed the potential of DNA barcoding to facilitate the identification of the cotton seed bug in field-collected specimens.

USDA is an equal opportunity provider and employer. Mass, energy, and exergy balances are analyzed for bio-oil production in a bench-scale fast pyrolysis system developed by the USDA's Agricultural Research Service (ARS) for the processing of commodity crops to fuel intermediates. Because mass balance closure is difficult to achieve due, in part, to the system's small size and complexity a linear programming optimization model is developed to improve closure of elemental balances without losing the overall representation of the pyrolysis products. The model results provide an opportunity to analyze true energy and exergy balances for the system. While energy comparisons are based on heating values, exergy flows are computed using statistical relationships and other standard techniques. Comparisons were made for a variety of biomass feedstocks including energy crops and various byproducts of agriculture and bioenergy industry. The mass model allows for proper accounting of sources of mass loss and suggestions for improved system performance. Energy recovery and exergetic efficiency are compared for a variety of pyrolysis product utilization scenarios including use of biochar and noncondensable gases as heat sources. Exergetic efficiencies show high potential for energy utilization when all the pyrolysis product streams can be recycled to recuperate their internal energy. The exergy analysis can be beneficial to developing exergetic life cycle assessments (ELCA) for the fast pyrolysis process as sustainable technology for advanced biofuels production.

These genera have been defined primarily on the basis of ascospore septation or number of conidial appendages. Due to a lack of DNA sequence data, phylogenetic placement of these genera within the Dothideomycetes, evaluation of monophyly, and questions about generic boundaries could not be adequately addressed in the past. Isolates of nearly all of the known species in these genera were studied genetically and morphologically. DNA sequence data were generated for the nSSU, ITS, nLSU, and RPB1 markers and analysed phylogenetically. These results placed the Planistromellaceae, herein recognised as a distinct family, in an unresolved position relative to other genera within the order Botryosphaeriales. Species representing the core genera of the Planistromellaceae formed a clade and evaluation of its topology revealed that previous morphology-based definitions of genera resulted in an artificial classification system. Alpakesa, Kellermania, Piptarthron, Planistroma, and Planistromella are herein recognised as belonging to the single genus Kellermania. The following new combinations are proposed: Kellermania crassispora, K. dasylirionis, K. macrospora, K. plurilocularis, and K. unilocularis. Five new species are described, namely K. confusa, K. dasylirionicola, K. micranthae, K. ramaleyae, and K. rostratae.

In plants, growth and life span are intertwined not only with nutrient acquisition from the soil and nutrition generation via photosynthesis but also with their unique modes of development and differentiation. How TOR functions in these processes has not yet been determined. To gain further insights, rapamycin-sensitive transgenic Arabidopsis thaliana lines (BP12) expressing yeast FK506 Binding Protein12 were developed. Inhibition of TOR in BP12 plants by rapamycin resulted in slower overall root, leaf, and shoot growth and development leading to poor nutrient uptake and light energy utilization. Experimental limitation of nutrient availability and light energy supply in wild-type Arabidopsis produced phenotypes observed with TOR knockdown plants, indicating a link between TOR signaling and nutrition/light energy status. Genetic and physiological studies together with RNA sequencing and metabolite analysis of TOR-suppressed lines revealed that TOR regulates development and life span in Arabidopsis by restructuring cell growth, carbon and nitrogen metabolism, gene expression, and rRNA and protein synthesis. Gain-and loss-of-function Ribosomal Protein S6 (RPS6) mutants additionally show that TOR function involves RPS6-mediated nutrition and light-dependent growth and life span in Arabidopsis.

While standard use-availability designs are helpful for establishing general patterns of species occurrence, they are limited in their ability to help researchers understand the underlying behavioural mechanisms that lead to observed space-use patterns. Based on spatially-explicit behavioural observations from coyotes Canis latrans in Yellowstone National Park, Wyoming, we estimated resource selection for specific behaviours (i.e. predatory, laying and travelling) and for all used locations irrespective of behaviour, to test whether resource selection is behaviour-specific and not generalizable across behaviours. Behaviour-specific models differed significantly from the model not partitioned by behaviour. In particular, the predatory model identified selection for mesic-meadows which have previously been documented to have high small-mammal abundance. The non-partitioned model, however, showed avoidance of this vegetation type. Our results show that resource selection differs between behaviours and suggest that standard techniques for estimation of resource selection might be of limited use for understanding the underlying behavioural mechanisms of space use. Future research should continue to improve on methods for partitioning fine-scale movement data obtained from telemetry collars into discrete movement bouts representative of different behaviours.

Defect-free lignin/PVA fibers were produced with radii which were observed to increase with lignin concentration and with the addition of CNCs. XPS and WCA results indicate a nonlinear relationship between the surface and the bulk compositions. A threshold around 50 wt % bulk composition was identified in which extensive partitioning of PVA and lignin components occurred on the surface below and above this value. In 75:25 wt % lignin/PVA solvent cast films, phase separated domains were observed. Using nanoscale thermal analyses, the continuous phase was determined to be lignin-rich and the discontinuous phase had a lignin/PVA dispersion. Importantly, the size of the phase separated domains was reduced by the addition of CNCs. When electrospun fiber surfaces were lignin-rich, the addition of CNCs affected their surfaces. In contrast, no surface effects were observed with the addition of CNCs in PVA-rich fibers. Overall, we highlight the importance of molecular interactions and phase separation on the surface properties of fibers from lignin as an abundant raw material for the fabrication of new functional materials.

In 1974/75, the prevalence of anemia in Chilean preschoolers was 18.8%. Since 2000, the Chilean Ministry of Health has combated anemia through the delivery of iron-fortified milk by the National Complementary Feeding Program (NCFP). Objective. To determine the prevalence of anemia in children aged 19 to 72 months who are beneficiaries of the NCFP. Methods. A cross-sectional representative sample of 224 beneficiaries of the NCFP aged 19 to 72 months from the Santiago and Valparaiso regions was recruited. Results. The mean (+/- SD) hemoglobin concentration was 12.3 +/- 1.0 g/dL. Four percent of all children studied were anemic. In simple linear regression analysis, it was observed that hemoglobin concentration was positively correlated with age (r = 0.23, p = .001). There was no association between hemoglobin concentration and duration of breastfeeding (r = -0.12, p = .175). The prevalence of anemia among the 69% of children consuming iron-fortified milk delivered by NCFP was 2.6%, as compared with 7.1% among children not consuming iron-fortified milk (p = 0.227). Consumption of iron-fortified milk did not show a positive signcant relationship with hemoglobin concentration (r = 0.063, p = .529). Similarly, multiple logistic regression did not show an association between consumption of fortified milk and anemia, after adjusting for sex, age, and breastfeeding (p = .150; OR = 0.98; 95% CI, 0.95 to 0.10). Conclusions. In 2009 anemia was riot a public health problem in Chilean children aged 19 to 72 months from Santiago and Valparaiso.

Plantain has superior cold tolerance compared with banana and a thorough understanding of the molecular mechanisms and responses of plantain to cold stress has great potential value for developing cold tolerant banana cultivars. In this study, we used iTRAQ-based comparative proteomic analysis to investigate the temporal responses of plantain to cold stress. Plantain seedlings were exposed for 0, 6, and 24 h of cold stress at 8 degrees C and subsequently allowed to recover for 24 h at 28 degrees C. A total of 3477 plantain proteins were identified, of which 809 showed differential expression from the three treatments. The majority of differentially expressed proteins were predicted to be involved in oxidation-reduction, including oxylipin biosynthesis, whereas others were associated with photosynthesis, photorespiration, and several primary metabolic processes, such as carbohydrate metabolic process and fatty acid beta-oxidation. Western blot analysis and enzyme activity assays were performed on seven differentially expressed, cold-response candidate plantain proteins to validate the proteomics data. Similar analyses of the seven candidate proteins were performed in cold-sensitive banana to examine possible functional conservation, and to compare the results to equivalent responses between the two species. Consistent results were achieved by Western blot and enzyme activity assays, demonstrating that the quantitative proteomics data collected in this study are reliable. Our results suggest that an increase of antioxidant capacity through adapted ROS scavenging capability, reduced production of ROS, and decreased lipid peroxidation contribute to molecular mechanisms for the increased cold tolerance in plantain. To the best of our knowledge, this is the first report of a global investigation on molecular responses of plantain to cold stress by proteomic analysis.

To determine the food sources of energy and 26 nutrients consumed by US adults the 2003-2006 National Health and Nutrition Examination Survey (NHANES) 24-h recall (Day 1) dietary intake data from a nationally representative sample of adults 19+ years of age (y) (n = 9490) were analyzed. An updated USDA Dietary Source Nutrient Database was developed for NHANES 2003-2006 using current food composition databases. Food grouping included ingredients from disaggregated mixtures. Mean energy and nutrient intakes from food sources were sample-weighted. Percentages of total dietary intake contributed from food sources were ranked. The highest ranked sources of energy and nutrients among adults more than 19 years old were: energy-yeast bread/rolls (7.2%) and cake/cookies/quick bread/pastry/pie (7.2%); protein-poultry (14.4%) and beef (14.0%); total fat-other fats and oils (9.8%); saturated fatty acids-cheese (16.5%) and beef (9.1%); carbohydrate-soft drinks/soda (11.4%) and yeast breads/rolls (10.9%); dietary fiber-yeast breads/rolls (10.9%) and fruit (10.2%); calcium-milk (22.5%) and cheese (21.6%); vitamin D-milk (45.1%) and fish/shellfish (14.4%); and potassium-milk (9.6%) and coffee/tea/other non-alcoholic beverages (8.4%). Knowledge of primary food sources of energy and nutrients can help health professionals design effective strategies to reduce excess energy consumed by US adults and increase the nutrient adequacy of their diets.

Fat-soluble plant pigments, carotenoids, are extensively studied micronutrient phytochemicals for their potential health benefits. It is noteworthy that specific carotenoids may be responsible for different protective effects against certain diseases. In addition, each carotenoid can be obtained from different types of plant foods. Considering the fact that the phytochemical content in foods can vary according to, but not limited to, the varieties and culture conditions, it is important to establish a database of phytochemicals in locally produced plant foods. Currently, information on individual carotenoid content in plant foods commonly consumed in Korea is lacking. As the first step to support the production and consumption of sustainable local plant foods, carotenoids and total phenolic contents of plant foods commonly consumed in Korea are presented and their potential biological functions are discussed in this review.

(Ericaceae) is a key evergreen understory species, often forming a subcanopy in forest stands. Little is known about the significance of R. maximum cover in relation to other forest structural variables. Only recently have studies used Global Positioning System (GPS) technology as a field-based method to map the perimeter of shrub patches as a means of estimating canopy cover. We assessed the viability of using GPS technology to accurately measure R. maximum canopy cover in mountainous terrain; and we compared canopy cover to other R. maximum abundance variables, forest structural attributes, and environmental factors. We selected forty 20 x 40 m permanent plots at Coweeta Hydrologic Laboratory in western North Carolina to employ a variety of methods (visual estimates, GPS, and x-y coordinate measurements) to estimate canopy cover of R. maximum within each plot. We found a positive relationship between the GPS method and the more accurate x-y coordinate measurements (r = 0.967, p < 0.001). We compared the GPS-derived estimates to other measures of R. maximum abundance and found positive relationships between cover and density (r(2) = 0.800, p < 0.001), basal area (r(2) = 0.747, p < 0.001), total biomass (r(2) = 0.761, p < 0.001), and leaf area index (r(2) = 0.761, p < 0.001). The GPS method is a reliable field-based technology to estimate evergreen canopy cover and it could be used to estimate more difficult to measure parameters of R. maximum, given the significant relationships found in this study.

Growth and flowering of Lilium hybrid 'Triumphator' and Begonia 'Bonfire' were evaluated in new and reused BP pots. Net photosynthesis was measured and macro- and micro-elements were analyzed in 'Triumphator' lily. Ultrastructure of epidermis cells of 'Triumphator' lily were analyzed using a low temperature-scanning electron microscope (LT-SEM). Surface changes, the weight, and macro- and micro-elements of the BP pots were also analyzed. When lilies were grown in BP 32 pots, root and shoot growth were inhibited, flowering was delayed and the net photosynthesis was negative, grana development, and starch granules were not observed as compared to those in BP 45 pots. Changes in the surface of BP 32 pots after forcing lilies (used once) showed a distinct space between feather fibers and other constituents which could be due to the chemical changes resulting from absorption of water. When BP pots were analyzed for pH and macro- and micro-elements, the pH and the concentration of ammonium nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and iron were significantly higher in the new BP 32 than those of BP 29 and BP 45 pots. Based on the growth and development of lily and begonia and net photosynthesis and grana development of lily, and foliar analysis of begonia grown in three different BP pots, it is concluded that BP 45 is recommended to grow lily and begonia when proper levels of nutrition are maintained during culture. Poor root growth and development of 'Triumphator' lily grown in new BP 32 pots could be associated with leaching of toxic substances once the pots absorb water during the culture.

The berries of these plants remain attached for a long period of time after an approximately 34 weeks period of development. The proteins in the developing seeds, germinating seeds, and seeds stored for various periods of time in moist or dry conditions and at 10A degrees C or 25A degrees C were examined by a polyacrylamide gel electrophoresis and an immunoblot analysis with antibodies to dehydrin and oleosin. Both dehydrin- and oleosin-like proteins were detected in early stages of seed development, as were proteins that are likely to function as seed storage proteins. Storage of seeds in dry conditions induced the expression of both dehydrin- and oleosin-like proteins, but only after an 8 weeks storage period. The levels of these proteins were considerably lower in the less dehydration tolerant A. japonica.

They were incubated under both facultative and anaerobic conditions to evaluate ethanol production on glucose, xylose, cellobiose, and a combination of all three sugars. The medium contained 50 g/L total sugar and 5 g/L yeast extract. The strains performed significantly better under facultative compared with anaerobic conditions. As expected, glucose was the most readily fermented sugar with similar to 100% fermentation efficiency (FE) under facultative conditions but only 5% to 16% FE anaerobically. Xylose utilization was 20% to 40% FE under facultative conditions but 9% to 25% FE anaerobically. Cellobiose was the least fermented sugar, at 18% to 27% FE facultatively and 8% to 11% anaerobically. Similar trends occurred in the sugar mixture. Under facultative conditions, strain 22-1-12 produced 19.6 g/L ethanol on glucose, but strain 14-2-6 performed best on xylose (4.5 g/L ethanol) and the sugar combination (8.0 g/L ethanol). Ethanol titers from glucose under anaerobic conditions were again highest with strain 22-1-12, but none of the strains produced ethanol from xylose. Future trials will evaluate nutrient addition to boost microaerophilic xylose fermentation. C1 [Gibbons, William] S Dakota State Univ, Biol & Microbiol Dept, Brookings, SD 57007 USA.

Herein, we describe studies to develop an autocontamination trapping system to disseminate Beauveria bassiana to control beetle populations. The standard trap for emerald ash borer in Canada is a light green prism trap covered in an insect adhesive and baited with (Z)-3-hexenol. We compared of green multifunnel traps, green intercept panel traps (both with and without fluo coating) and green prism traps for capturing emerald ash borer in a green ash plantation. The coated green multifunnel traps captured significantly more males and more females than any other trap design. We examined the efficacy of two native B. bassiana isolates, INRS-CFL and L49D1AA. In a field experiment the INRS-CFL isolate attached to multifunnel traps in autocontamination chambers retained its pathogenicity to emerald ash borer adults for up to 43 d of outdoor exposure. Conidia germination of the INRS-CFL isolate was >69% after outdoor exposure in the traps for up to 57 d. The L49D1AA isolate was not pathogenic in simulated trap exposures and the germination rate was extremely low (<5.3%). Mean (+/- SEM) conidia loads on ash borer adults after being autocontaminated in the laboratory using pouches that had been exposed in traps out of doors for 29 d were 579,200 (+/- 86,181) and 2,400 (+/- 681) for the INRS-CFL and the L49-1AA isolates, respectively. We also examined the fungal dissemination process under field conditions using the L49-1AA isolate in a green ash plantation. Beetles were lured to baited green multifunnel traps with attached autocontamination chambers. Beetles acquired fungal conidia from cultures growing on pouches in the chambers and were recaptured on Pestick-coated traps. In total, 2,532 beetles were captured of which 165 (6.5%) had fungal growth that resembled B. bassiana. Of these 25 beetles were positive for the L49-1AA isolate. C1 [Lyons, D.

Eggs, neonates, third instars, fifth instars, and early stage pupae were irradiated at target doses of 60, 90, 120, or 150 Gy or left untreated as controls in replicated factorial experiments and survival to the adult stage was recorded. Tolerance to radiation generally increased with increasing age and developmental stage. A radiation dose of 120 Gy applied to eggs and neonates prevented adult emergence. A dose of 150 Gy prevented adult emergence in larvae at all stages. In large-scale validation tests, a radiation dose of 150 Gy applied to fifth instars in diet, apples or peppers resulted in no survival to the adult stage in 37,947 treated individuals. Pupae were more radio tolerant than larvae, and late stage pupae were more tolerant than early stage pupae. Radiation treatment of late pupae at 350 and 400 Gy resulted in three and one fertile eggs in 4,962 and 4,205 total eggs laid by 148 and 289 mating pairs, respectively. For most commodities, the fifth instar is the most radio tolerant life stage likely to occur with the commodity; a minimum radiation dose of 150 Gy will prevent adult emergence from this stage and meets the zero tolerance requirement for market access. For traded commodities such as table grapes that may contain E. postvittana pupae, a radiation dose >400Gy may be necessary to completely sterilize emerging adults. After review of the literature, a generic radiation treatment of 250 Gy is proposed for tortricid eggs and larvae in regulated commodities.

A threshold of 20 moths/trap/wk was used to initiate monitoring for larval infestations. The percentage of stalks with larvae on plant surfaces was directly related to the number of moths trapped. Reductions in borer injury and adult emergence were detected when a threshold of >5% of stalks with larvae present on plant surfaces was used to trigger insecticide applications. Novaluron provided superior control compared with beta-cyauthrin; novaluron treated plots were associated with a 14% increase in sugar production. A greenhouse experiment investigating establishment and behavior of E. loftini larvae on two phenological stages of stalkborer resistant, HoCP 85-845, and susceptible, HoCP 00-950, sugarcane cultivars determined that more than half of larvae on HoCP 00-950 and >25% on HoCP 85-845 tunneled inside leaf mid-ribs within 1 d of eclosion, protected therein from biological and chemical control tactics. Exposure time of larvae averaged <1 wk for all treatments and was shortest on immature HoCP 00-950 and longest on mature HoCP 85-845. This study shows a short window of vulnerability of E. loftini larvae to insecticide applications, and demonstrates the potential utility of pheromone traps for improving insecticide intervention timing such that a single properly timed application may be all that is required.

TI Development of a Plant-Based Threshold for Tarnished Plant Bug (Hemiptera: Miridae) in Cotton SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE Lygus; tarnished plant bug; sampling; threshold; cotton ID MISSISSIPPI RIVER DELTA; PYRETHROID RESISTANCE; FLOWERING COTTON; UNITED-STATES; POPULATIONS; HETEROPTERA; INSECTICIDE; ACEPHATE; BIOLOGY AB The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is an important pest of cotton, Gossypium hirsutum L., in the mid-southern United States. It is exclusively controlled with foliar insecticide applications, and sampling methods and thresholds need to be revisited. The current experiment was designed to establish a plant-based threshold during the flowering period of cotton development. Experiments were conducted in Mississippi in 2005 and 2006, Arkansas in 2005, and Louisiana in 2005 through 2008. Treatments consisted of various combinations of thresholds based on the percentage of dirty squares that were compared with the current threshold with a drop cloth or automatic weekly applications. Dirty squares were characterized as those with yellow staining on the developing bud resulting from tarnished plant bug excrement. Treatments consisted of 5, 10, 20, and 30% dirty squares. Each plot was sampled weekly, and insecticides were applied when the mean of all replications of a particular treatment reached the designated threshold. At the end of the season, plots were harvested and lint yields were recorded. Differences were observed in the number of applications and yields among the different treatments. The 10% dirty squares threshold resulted in a similar economic return compared with the drop cloth. A threshold of 10% dirty squares resulted in a similar number of insecticide applications, yields, and economic returns compared with that observed with the drop cloth. These results suggest that a threshold of 10% dirty squares could be used to trigger insecticide applications targeting tarnished plant bugs in flowering cotton. C1 [Gore, J.; Cook, D.

Studies conducted in Puerto Rico determined that synthetic P. minor pheromone lures preaged 120 d in the field caught similar number of males as lures not aged (fresh). Molecular analysis of trapped mealybug males using mitochondrial cytochrome oxidase-1, the internal transcriber space two locus, and 28S-D2 gene showed the pheromone traps to be species specific. Traps baited with P. minor pheromone were used to monitor the pest in south Florida and to locate potential infestations. P. minor males were found at all locations studied in South Florida and were present in low numbers (1.03 +/- 0.69 mean +/- SE/trap/14 d). Over 14,000 terminals, fruit, and flowers were visually inspected over a 6 mo period of peak trap catches before the first adult P. minor female was found. The synthetic pheromone lures proved to be an effective tool to locate and monitor this pest new to the continental United States.

The objective of the study was to get insight into the potential of managing these pests using the host-marking technique. Observations were done on mango slices marked by the flies and treated with aqueous solutions of fecal matter of the flies, respectively. In both host-marking and fecal matter experiments, C. cosyra, which is the most destructive species of the four on mango, was exceptional. It only discriminated against hosts treated with its fecal matter but with lower sensitivity while C. capitata and C. fasciventris discriminated against hosts marked by it or treated with its fecal matter and with higher sensitivity. Our results provide evidence for potential of managing some of the major fruit fly species infesting mango in Africa using the host-marking pheromone of the mango fruit fly, C. cosyra.

Bacillus thuringiensis Berliner (Bt) crops have been instrumental in controlling tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), a pest that has developed resistance to many common insecticides once used for its management. In our study, microsatellite markers were applied to investigate the genetic structure and patterns of gene flow among Brazilian populations of H. virescens from cotton, Gossypium hirsutum L., and soybean, Glycine max (L.) Merr., fields, aiming to propose means to improve its management in the field. In total, 127 alleles were found across nine microsatellites loci for 205 individuals from 12 localities. Low levels of gene flow and moderate to great genetic structure were found for these populations. Host plant association, crop growing season, and geographic origin were not responsible for the genetic structuring among Brazilian populations of H. virescens. Other factors, such as demographic history and seasonal variability of intrapopulation genetic variation, were suggested to be molding the current pattern of genetic variability distribution.

It inhabits areas in Mexico, Central and South America, and the Caribbean with occasional infestations having occurred in the southern tier states (California, Florida, and Texas) of the United States. This fly is associated with many plant species and is a major pest of mango and plum. We examine the genetic diversity of the West Indian fruit fly based on mitochondrial COI and ND6 DNA sequences. Our analysis of 349 individuals from 54 geographic collections from Mexico, Central America, the Caribbean, and South America detected 61 haplotypes that are structured into three phylogenetic clades. The distribution of these clades among populations is associated with geography. Six populations are identified in this analysis: Mesoamerica, Central America, Caribbean, western Mexico, Andean South America, and eastern Brazil. In addition, substantial differences exist among these genetic types that warrants further taxonomic review.

Study animals in treatment and control groups were confined in 38.8 ha game-fenced and densely vegetated treatment plots in South Texas. Tick densities during years 1 and 7 served as untreated pre- and posttreatment comparisons and treatments occurred during years 2 through 5. Reductions in tick densities in the treatment plot were compared against tick densities in a control plot having similar vegetation and numbers of untreated deer. During years of treatment, indices of control pressure ranged from 18.2 to 82.6 for nymphs and 16.9-78.7 for adults, and efficacy, expressed as percentage control during the final year of treatment, was 77.2 and 85.0%, respectively, for nymphal and adult ticks. These data show that acaricidal collar treatments provide efficacies very similar to those achieved with the existing ivermectin-medicated bait and '4-Poster' topical treatment technologies to control ticks feeding on wild white-tailed deer.

Drawing from 13 case studies from across the United States, this article describes best management practices (BMP) that emerged from the data for facilitating the development of Community Wildfire Protection Plans (CWPPs) and ensuring that planning leads to action on the ground. Three BMPs are emphasized: (1) paying attention to problem framing, (2) choosing a scale where participants can make things happen, and (3) taking steps to facilitate implementation and ensure long-term success. These BMPs were found to hold true despite considerable diversity across the cases. C1 [Williams, Daniel R.] US Forest Serv, USDA, Rocky Mt Res Stn, Ft Collins, CO 80526 USA.

TI How Can We Span the Boundaries between Wildland Fire Science and Management in the United States? SO JOURNAL OF FORESTRY LA English DT Article DE fire science; boundary organization; fire management; Joint Fire Science Program; technology transfer ID CLIMATE FORECASTS; DECISION-MAKING; POLICY; INFORMATION; INTERFACE; PERCEPTIONS AB In 2009, the federal Joint Fire Science Program (JFSP) initiated a national network of boundary organizations, known as regional fire science consortia, to accelerate the awareness, understanding, and use of wildland fire science. Needs assessments conducted by consortia in eight regions of the United States are synthesized here using a case survey approach. Although regions used different methods based on their different ecosystems, geography, and demography, results showed striking similarities in how fire science is accessed and used, barriers to its use, and research information needed. Use of Internet-based information is universally high; however, in-person knowledge exchange is preferred. Obstacles to fire science application include lack of time, resources, and access to the most relevant information as well as communication barriers between scientists and managers. Findings show a clear need for boundary organizations to span fire science and management to (a) organize and consolidate fire science information through easily accessible websites and (b) strengthen relationships between scientists and managers to facilitate production and communication of science relevant to managers' concerns. This article contributes to boundary spanning theory by underscoring and documenting the advantages of regionally focused boundary organizations in meeting user needs and building bridges between fire scientists and managers.

Uncertainty derives from natural spatial and temporal variation and also from knowledge uncertainty in measurement and models. For example, when estimating forest biomass, researchers commonly report sampling uncertainty but rarely propagate the uncertainty in the allometric equations used to estimate tree biomass, much less the uncertainty in the selection of which allometric equations to use. Change over time may have less uncertainty than a single measurement, if the measures are consistently biased, as by the use of inaccurate allometric equations or soil sampling techniques. Quantifying uncertainty is not as difficult as is sometimes believed. Here, we describe recent progress in quantifying uncertainty in biomass, soils, and hydrologic inputs and outputs, using examples from the Hubbard Brook Experimental Forest, New Hampshire, USA.

While some countries have greatly reduced their reliance on landfills, there remain thousands of landfills that require aftercare. The development of cost-effective strategies for landfill aftercare is in society's interest to protect human health and the environment and to prevent the emergence of landfills with exhausted aftercare funding. The Evaluation of Post-Closure Care (EPCC) methodology is a performance-based approach in which landfill performance is assessed in four modules including leachate, gas, groundwater, and final cover. In the methodology, the objective is to evaluate landfill performance to determine when aftercare monitoring and maintenance can be reduced or possibly eliminated. This study presents an improved gas module for the methodology. While the original version of the module focused narrowly on regulatory requirements for control of methane migration, the improved gas module also considers best available control technology for landfill gas in terms of greenhouse gas emissions, air quality, and emissions of odoriferous compounds. The improved module emphasizes the reduction or elimination of fugitive methane by considering the methane oxidation capacity of the cover system. The module also allows for the installation of biologically active covers or other features designed to enhance methane oxidation. A methane emissions model, CALMIM, was used to assist with an assessment of the methane oxidation capacity of landfill covers. (c) 2012 Elsevier Ltd. All rights reserved. C1 [Morris, Jeremy W.

This species has a convective flow system that moves gases from younger leaves through submerged parts to older leaves, aerating submerged parts. Petiolar air canals are the convective flow pathways. This study describes the structure of these canals, how this structure varies with water depth, and models how convective flow varies with depth. Methods: Nymphaea odorata plants were grown at water depths from 30 to 90 cm. Lamina area, petiolar cross-sectional area, and number and area of air canals were measured. Field-collected leaves and leaves from juvenile plants were analyzed similarly. Using these data and data from the literature, we modeled how convective flow changes with water depth. Key results: Petioles of N. odorata produce two central pairs of air canals; additional pairs are added peripherally, and succeeding pairs are smaller. The first three pairs account for 96% of air canal area. Air canals form 24% of petiolar cross-sectional area. Petiolar and air canal cross-sectional areas increase with water depth. Petiolar area scales with lamina area, but the slope of this relationship is lower in 90 cm water than at shallower depths. In our model, the rate of convective flow varied with depth and with the balance of influx to efflux leaves. Conclusions: Air canals in N. odorata petioles increase in size and number in deeper water but at a decreasing amount in relation to lamina area. Convective flow also depends on the number of influx to efflux laminae. C1 [Richards, Jennifer H.; Bishop, Kristin] Florida Int Univ, Dept Biol Sci, Miami, FL 33155 USA.

TI DEEP SEQUENCING OF AMPLICONS REVEALS WIDESPREAD INTRASPECIFIC HYBRIDIZATION AND MULTIPLE ORIGINS OF POLYPLOIDY IN BIG SAGEBRUSH (ARTEMISIA TRIDENTATA; ASTERACEAE) SO AMERICAN JOURNAL OF BOTANY LA English DT Article DE Artemesia tridentata; Asteraceae; gene discordance; haplotype clustering; networks; phylogeny; pyrosequencing; reticulate evolution ID NARROW HYBRID ZONE; SUBGENUS TRIDENTATAE; PHYLOGENETIC ANALYSIS; MAXIMUM-LIKELIHOOD; EVOLUTIONARY; SELECTION; AUTOPOLYPLOIDY; BRASSICACEAE; SPECIATION; ADAPTATION AB Premise of the study: Hybridization has played an important role in the evolution and ecological adaptation of diploid and polyploid plants. Artemisia tridentata (Asteraceae) tetraploids are extremely widespread and of great ecological importance. These tetraploids are often taxonomically identified as A. tridentata subsp. wyomingensis or as autotetraploids of diploid subspecies tridentata and vaseyana. Few details are available as to how these tetraploids are formed or how they are related to diploid subspecies. Methods: We used amplicon sequencing to assess phylogenetic relationships among three recognized subspecies: tridentata, vaseyana, and wyomingensis. DNA sequence data from putative genes were pyrosequenced and assembled from 329 samples. Nucleotide diversity and putative haplotypes were estimated from the high-read coverage. Phylogenies were constructed from Bayesian coalescence and neighbor-net network analyses. Key results: Analyses support distinct diploid subspecies of tridentata and vaseyana in spite of known hybridization in ecotones. Nucleotide diversity estimates of populations compared to the total diversity indicate the relationships are predominately driven by a small proportion of the amplicons. Tetraploids, including subspecies wyomingensis, are polyphyletic occurring within and between diploid subspecies groups. Conclusions: Artemisia tridentata is a species comprising phylogenetically distinct diploid progenitors and a tetraploid complex with varying degrees of phylogenetic and morphological affinities to the diploid subspecies. These analyses suggest tetraploids are formed locally or regionally from diploid tridentata and vaseyana populations via autotetraploidy, followed by introgression between tetraploid groups. Understanding the phylogenetic vs. ecological relationships of A. tridentata subspecies will have bearing on how to restore these desert ecosystems.

TI WITHIN- AND TRANS-GENERATIONAL PLASTICITY AFFECTS THE OPPORTUNITY FOR SELECTION IN BARBED GOATGRASS (AEGILOPS TRIUNCIALIS) SO AMERICAN JOURNAL OF BOTANY LA English DT Article DE secondary invasion; serpentine; annual grasslands; canalization; maternal effects ID QUANTITATIVE-GENETIC MODEL; TRANSGENERATIONAL PLASTICITY; PHENOTYPIC PLASTICITY; EVOLVABILITY; ASSIMILATION; CANALIZATION; ENVIRONMENTS; POPULATIONS; ADAPTATION; RESISTANCE AB Premise of the study: Environments are composed of selective agents, and environments may also modify the efficacy of these agents. Environments affect the rate of maximum evolutionary change by influencing variation in relative fitness (i.e., the opportunity for selection, or I). Within-and transgenerational plastic environmental responses may affect I, speeding or slowing processes of local adaptation. Methods: We determined whether environmental factors affected the opportunity for selection (I) in Aegilops triuncialis (barbed goatgrass) by measuring I as a within-and transgenerational plastic response to two maternal glasshouse environments (serpentine/dry and loam/moist). We also determined whether this species' two most common genetic lineages (determined by DNA microsatellite length polymorphism) varied in response to glasshouse treatments. Key Results: Opportunity for selection was less for plants grown in the dry serpentine environment than for plants grown in the moist loam environment. This response varied between genetic lineages. The east lineage exhibited a within-generation response to the dry serpentine environment. For both seed mass and average seed weight in this lineage, the opportunity for selection was lower in dry serpentine than in moist loam. The west lineage had a transgenerational response to the dry serpentine such that the opportunity for selection for seed number and seed mass was lower for plants produced by mothers grown in dry serpentine than for plants produced by mothers in moist loam. Conclusions: Phenotypic variation in relative fitness is constrained by the dry serpentine environment, which leads to lower evolvability in this environment. Within-and transgenerational effects of the environment may slow local adaptation to serpentine soils. C1 [Espeland, Erin K.] USDA ARS, Pest Management Res Unit, Sidney, MT 59270 USA.

TI The Market for US Livestock Feed Proteins SO APPLIED ECONOMIC PERSPECTIVES AND POLICY LA English DT Article DE Bovine spongiform encephalopathy (BSE); ethanol co-product; feedgrain; meat and bone meal; soybean; urea; Q13 ID SUBSTITUTION; ELASTICITIES AB Parameters that characterize markets for livestock feed ingredients and inform an increasing array of policies motivated by a range of environmental, market, and animal disease issues are largely absent from the literature, which necessitates the use of often misleading assumptions in analyses of proposed feed-market policies. Such parameters are derived here from a theoretically consistent, dual translog cost model of U.S. protein and energy feed markets. Own-price elasticities ranged from a relatively inelastic 0.139 for feedgrains to a relatively elastic 0.568 for meat and bone meal (MBM). The cross elasticity for ethanol co-products and oilseed meals (0.168) is larger than the elasticity with co-products and feedgrains (0.024). Higher prices for protein feeds likely result in some substitution of feed grains for some protein (e.g. corn by oilseed meals 0.125), which may also partially account for the relatively small feedgrains cross elasticity. Policies implemented as a result of bovine splongiform encephalopathy adversely affected the share of total costs attributed to MBM, but had a positive effect on oilseed meal cost share.

The largest of these epizootics, affecting more birds and countries than the other 29 epizootics combined, has been the H5N1 HPAI, which began in Guangdong China in 1996, and has killed or resulted in culling of over 250 million poultry and/or wild birds in 63 countries. Most countries have used stamping-out programs in poultry to eradicate H5N1 HPAI. However, 15 affected countries have utilized vaccination as a part of the control strategy. Greater than 113 billion doses were used from 2002 to 2010. Five countries have utilized nationwide routine vaccination programs, which account for 99% of vaccine used: 1) China (90.9%), 2) Egypt (4.6%), 3) Indonesia (2.3%), 4) Vietnam (1.4%), and 5) Hong Kong Special Administrative Region (<0.01%). Mongolia, Kazakhstan, France, The Netherlands, Cote d'Ivoire, Sudan, North Korea, Israel, Russia, and Pakistan used <1% of the avian influenza (AI) vaccine, and the AI vaccine was targeted to either preventive or emergency vaccination programs. Inactivated AI vaccines have accounted for 95.5% of vaccine used, and live recombinant virus vaccines have accounted for 4.5% of vaccine used. The latter are primarily recombinant Newcastle disease vectored vaccine with H5 influenza gene insert. China, Indonesia, Egypt, and Vietnam implemented vaccination after H5N1 HPAI became enzootic in domestic poultry. Bangladesh and eastern India have enzootic H5N1 HPAI and have not used vaccination in their control programs. Clinical disease and mortality have been prevented in chickens, human cases have been reduced, and rural livelihoods and food security have been maintained by using vaccines during HPAI outbreaks. However, field outbreaks have occurred in vaccinating countries, primarily because of inadequate coverage in the target species, but vaccine failures have occurred following antigenic drift in field viruses within China, Egypt, Indonesia, Hong Kong, and Vietnam. The primary strategy for HPAI and H5/H7 low pathogenicity notifiable avian influenza control will continue to be immediate eradication using a four-component strategy: 1) education, 2) biosecurity, 3) rapid diagnostics and surveillance, and 4) elimination of infected poultry. Under some circumstances, vaccination can be added as an additional tool within a wider control strategy when immediate eradication is not feasible, which will maintain livelihoods and food security, and control clinical disease until a primary strategy can be developed and implemented to achieve eradication.

Stamping-out policies of euthanatizing infected and at-risk flocks has been an effective control tool, but it comes at a high social and economic cost. Efforts to identify alternative ways to respond to outbreaks without widespread stamping out has become a goal for organizations like the World Organisation for Animal Health. A major issue with vaccination for avian influenza is trade considerations because countries that vaccinate are often considered to be endemic for the disease and they typically lose their export markets. Primarily as a tool to promote trade, the concept of DIVA (differentiate infected from vaccinated animals) has been considered for avian influenza, but the goal for trade is to differentiate vaccinated and not-infected from vaccinated and infected animals because trading partners are unwilling to accept infected birds. Several different strategies have been investigated for a DIVA strategy, but each has advantages and disadvantages. A review of current knowledge on the research and implementation of the DIVA strategy will be discussed with possible ways to implement this strategy in the field. The increased desire for a workable DIVA strategy may lead to one of these ideas moving from the experimental to the practical. C1 USDA ARS, SE Poultry Res Lab, Athens, GA 30605 USA.

All three countries reported outbreaks of low pathogenic notifiable avian influenza in poultry during this period. The reports involved outbreaks of H5N2 among commercial turkeys in Canada in 2009 and 2010; outbreaks of H5N3 in turkeys in 2009, H5N2 in chickens in 2010, H7N3 in turkeys in 2011, and H7N9 in chickens, turkeys, geese, and guinea fowl in 2011 in the United States; and multiple outbreaks of H5N2 in chickens in Mexico in 2009, 2010, and 2011. Outbreaks of pandemic H1N1 infections in turkey breeder flocks were reported in Canada in 2009 and in the United States in 2010. Active surveillance of live bird markets in the United States led to the detection of H2, H3, H4, H5, H6, and H10 subtypes. Despite the fact that wild bird surveillance programs underwent contraction during this period in both Canada and the United States, H5 and H7 subtypes were still detected.

However, such disease control measures may disrupt business continuity and impact food security, since egg production facilities often do not have sufficient capacity to store eggs for prolonged periods. We propose the incorporation of a holding time before egg movement in conjunction with targeted active surveillance as a novel approach to move eggs from flocks within a control area with a low likelihood of them being contaminated with HPAI virus. Holding time reduces the likelihood of HPAI-contaminated eggs being moved from a farm before HPAI infection is detected in the flock. We used a stochastic disease transmission model to estimate the HPAI disease prevalence, disease mortality, and fraction of internally contaminated eggs at various time points postinfection of a commercial table-egg layer flock. The transmission model results were then used in a simulation model of a targeted matrix gene real-time reverse transcriptase (RRT)-PCR testing based surveillance protocol to estimate the time to detection and the number of contaminated eggs moved under different holding times. Our simulation results indicate a significant reduction in the number of internally contaminated eggs moved from an HPAI-infected undetected flock with each additional day of holding time. Incorporation of a holding time and the use of targeted surveillance have been adopted by the U.S. Department of Agriculture in their Draft Secure Egg Supply Plan for movement of egg industry products during an HPAI outbreak.

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

Although, a wide diversity of influenza viruses have been isolated from gulls, two hemagglutinin subtypes (H13 and H16) are rarely detected in other avian groups, and existing surveillance data suggests they are maintained almost exclusively within gull populations. In order to evaluate the host range of these gull-adapted influenza subtypes and to characterize viral infection in the gull host, we conducted a series of challenge experiments, with multiple North American strains of H13 LPAI virus in ring-billed gulls (Larus delawarensis), mallards (Anas platyrhynchos), chickens (Gallus domesticus), and turkeys (Meleagris gallopavo). The susceptibility to H13 LPAI viruses varied between species and viral strain. Gulls were highly susceptible to H13 LPAI virus infection and excreted virus via the oropharynx and cloaca for several days. The quantity and duration of shedding was similar between the two routes. Turkeys and ducks were resistant to infection with most strains of H13 LPAI virus, but low numbers of inoculated birds were infected after challenge with specific viral strains. Chickens were refractory to infection with all strains of H13 LPAI virus they were challenged with. The experimental results presented herein are consistent with existing surveillance data on H13 LPAI viruses in birds, and indicate that influenza viruses of the H13 subtype are strongly host-adapted to gulls, but rare spill-over into aberrant hosts (i.e., turkeys and ducks) can occur.

In Denmark, the surveillance consisted of passive surveillance of wild birds found dead or sick across Denmark and active surveillance of apparently healthy live birds in waterfowl reservoirs and along migratory flyways, birds living in proximity to domestic poultry, and hunted game birds. Dead birds were sampled by oropharyngeal swabbing. Healthy live wild birds were captured with nets, traps, or by hand and were sampled by swabbing of the oropharyngeal and cloacal tracts, or swabs were collected from fresh fecal droppings. Hunted game birds were delivered to game-handling establishments, where each bird was sampled by oropharyngeal and cloacal swabbing. During the 2007-10 period, a total of 11,055 wild birds were sampled in Denmark, of which 396 were birds that were found dead. In Greenland, samples were collected mainly from fecal droppings in breeding areas. Samples from 3555 live and apparently healthy wild birds were tested. All swab samples were tested by pan-influenza reverse transcriptase PCR (RT-PCR), and the positive samples were further tested by H5/H7 specific RT-PCRs. H5/H7-positive samples were subjected to hemagglutination cleavage site sequencing for pathotyping. In addition, all RT-PCR positive samples were subjected to virus isolation, and the virus isolates were subsequently subtyped. In Denmark, low pathogenic (LP) H5 viruses were detected throughout the period, in addition to a few LPAI H7 and several other subtypes. In Greenland, very few samples were positive for AI. None of them were found to be of the H5 or H7 subtypes by RT-PCR. Isolation of these viruses in eggs was unsuccessful; thus, they were not subtyped further. The findings did, however, demonstrate the presence of LPAI viruses in Greenland. For several water bird species overwintering in North America and northwest Europe, respectively, Greenland constitutes a common breeding area. This raises the possibility that viruses could be transmitted to North America via Greenland and vice versa. In Denmark, the screenings for AT showed LPAI viruses to be naturally occurring in the wild bird population, particularly in waterfowl. The occurrence of AI viruses in the wild bird population may pose a risk for AI infections in Danish poultry.

These regions constitute an area of transit, stops during migration, and nesting for many different bird species. From September 2010 to September 2011,a wild bird surveillance study was conducted in these regions to identify avian influenza viruses. Biological samples consisting of cloacal and tracheal swabs and fecal samples were collected from wild birds of different ecological groups, including waterfowl and sea- and land-based birds, in places of mass bird accumulations in Sivash Bay and the Utlyuksky and Molochniy estuaries. The sampling covered the following wild bird biological cycles: autumn migration, wintering, spring migration, nesting, and postnesting seasons. A total of 3634 samples were collected from 66 different species of birds. During the autumn migration, 19 hemagglutinating viruses were isolated, 14 of which were identified as low pathogenicity avian influenza (LPAI) virus subtypes H1N?, H3N8, H5N2, H7N?, H8N4, H10N7, and H11N8. From the wintering samples, 45 hemagglutinating viruses were isolated, 36 of which were identified as LPAI virus subtypes H1N I, H1N? H1N2, H4N?, H6N1, H7N3, H7N6, H7N7, H8N2, H9N2, H10N7, H10N4, H11N2, H12N2, and H15N7. Only three viruses were isolated during the spring migration, nesting, and postnesting seasons (serotypes H6, H13, and H16). The HA and NA genes were sequenced from the isolated H5 and NI viruses, and the phylogenetic analysis revealed possible ecological connections between the Azov and Black Sea regions and Europe. The LPAI viruses were isolated mostly from mallard ducks, but also from shellducks, shovelers, teals, and white-fronted geese. The rest of the 14 hemagglutinating viruses isolated were identified as different serotypes of avian paramyxoviruses (APMV-1, APMV-4, APMV-6, and APMV-7). This information furthers our understanding of the ecology of avian influenza viruses in wild bird species.

Long-term watershed and natural elevation gradient studies at the Hubbard Brook Experimental Forest and in the surrounding region show surprising results demonstrating the effects of climate change on hydrologic variables (e.g., evapotranspiration, streamflow, soil moisture); the importance of changes in phenology on water, carbon, and nitrogen fluxes during critical seasonal transition periods; winter climate change effects on plant and animal community composition and ecosystem services; and the effects of anthropogenic disturbances and land-use history on plant community composition. These studies highlight the value of long-term integrated research for assessments of the subtle effects of changing climate on complex ecosystems.

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

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

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

We studied behavior of the specialist weevil Rhinoncomimus latipes Korotyaev, a biological control agent of mile-a-minute weed, Persicaria perfoliata (L.) H. Gross, by releasing weevils at the forest edge and monitoring their colonization of potted host plants arrayed along the edge, out into the open field, and into the forest. Both distance from the release cage and habitat where plants were located affected colonization, with more than twice as many weevils found on plants at 2 m than at 6 or 14 m; at 14 m, 6-8 times as many weevils colonized plants along the forest edge compared with plants in the open field or within the forest. In a second experiment, weevils that were released in an open field 12 m from the forest edge initially flew in all directions, but again ultimately colonized more plants at the edge than out in the open field. This species may be adapted to seek host plants at the forest edge, because P. perfoliata generally is found in riparian corridors in its native range and along forest edges in North America. Results suggest that R. latipes will move successfully to new P. perfoliata patches along wooded edges, but may not readily locate isolated patches in the open or those embedded in forests.

TI Effects of Flour Conditioning on Cannibalism of T. castaneum Eggs and Pupae SO ENVIRONMENTAL ENTOMOLOGY LA English DT Article DE cannibalism; flour conditioning; Tribolium castaneum; population dynamics ID TRIBOLIUM-CASTANEUM; BEETLE AB Cannibalism is a very important factor regulating population dynamics of the red flour beetle. After several days of feeding, the flour becomes conditioned by the beetles, which can affect rates of cannibalism. Flour conditioning is caused by an accumulation of feces, pheromones, and ethylquinone, which is a repellent produced by the beetles. We determined the effect of five different levels of flour conditioning on cannibalism of red flour beetle eggs and pupae by adult and larval stages. Larvae had the highest rates of egg cannibalism (12 eggs eaten over the 4-d period) followed by female adults (seven eggs consumed). Adult males had the lowest rates of cannibalism with only two eggs consumed. Cannibalism of eggs by females was correlated negatively with the level of flour conditioning. There was no effect of flour conditioning on egg or pupal cannibalism by larvae or adult males. Cannibalism by adult females may decrease as the level of flour conditioning increases because females may spend less time tunneling in highly conditioned flour and more time trying to disperse to other areas that are better for oviposition.

We quantified the use of protein immunomarks in tracking emigration of spined soldier bug, Podisus maculiventris Say (Hemiptera: Pentatomidae) and predation on the hornworm caterpillar, Manduca sexta L. (Lepidoptera: Sphingidae). An external protein mark was topically applied to adult P. maculiventris to assess persistence under field conditions for > 2 wk. Internal marks were incorporated into the artificial diet of M. sexta to test retention of the internal mark in the prey and uptake of the mark by predators. External marks remained detectable in 100% of individuals after 3 d and > 50% still tested positive at 12 d after application in the field. Internal diet-based marking was also effective in tracking feeding by P. maculiventris on M. sexta, especially using rabbit IgG that was far more persistent than chicken IgY. Nearly 90% of stink bugs fed caterpillars previously reared on protein-enriched diet retained their mark for 24 h. Surprisingly, diet concentration and time reared on diet had comparatively little impact on mark retention. Development on unmarked tomato leaves clearly diluted the initial diet mark, but plant-reared individuals that were marked were still successfully detected in 35 and 20% of the predators.

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

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

Highest percent hatch and fastest development occurred when eggs were held at 5 degrees C for 56 or 84 d followed by holding at 10 degrees C. A model estimated the lower threshold for postdiapause development to be 2 degrees C. The effect of temperature on egg hatch was similar at photoperiods of 12: 12 and 16: 8 (L:D) h, suggesting egg development is not governed by photoperiod or light exposure. Collectively these data indicate that S. camptodromus eggs laid in the spring and summer go through an aestivo-hibernal diapause that is maintained by warm temperatures and that development resumes when temperatures drop, in parallel with the development of hemlock woolly adelgid. This concurrent development allows S. camptodromus eggs to hatch while hemlock woolly adelgid is laying eggs. This synchrony between the development of S. camptodromus eggs and the overwintering adelgid suggest this beetle may be a good candidate for the biological control of the hemlock woolly adelgid.

TI Statistical Properties of Alternative National Forest Inventory Area Estimators SO FOREST SCIENCE LA English DT Article DE nonresponse; Polya posterior AB The statistical properties of potential estimators of forest area for the USDA Forest Service's Forest Inventory and Analysis (FIA) program are presented and discussed. The current FIA area estimator is compared and contrasted with a weighted mean estimator and an estimator based on the Polya posterior, in the presence of nonresponse. Estimator optimality is evaluated both theoretically and via simulation under bias and mean squared error criteria. The results indicate that, under realistic conditions, the current FIA area estimator can sometimes result in substantial bias and have a higher mean squared error than both of the alternative estimators. This finding is of special interest because the same factor that contributes to this increased bias and variance applies to all area-based FIA estimates. The weighted mean and Polya posterior estimators gave similar results for estimating the total area of a domain. It is concluded that the main advantage of the latter approach is that many other statistics are obtainable because the entire population distribution is estimated from the same sampling effort. The cost of this advantage for the Polya posterior approach is that a single result requires many more computer operations, a cost that has become virtually ignorable over the past decade. FOR.

More recently, SG has been widely used by ecologists as a plant functional trait and as a key variable in estimates of biomass. However, sampling wood to determine SG can be problematic; at present, the most common method is sampling with an increment borer to extract a bark-to-pith core-a difficult task requiring considerable physical effort and sometimes repeated borings to hit the pith, with potential to damage the trunk of small trees. Here, we test a novel sampling method that reduces the effort to obtain an adequate increment core and results in less wood extracted from the tree. The Wiemann approximation predicts the point along a radius at which the wood SG equals the disk cross-sectional SG. When SG changes linearly across the radius, the point of approximation is at two-thirds of the radial distance. As a test, we compare SG at various points along the radius with the true SG of the disk. At all points except the point of approximation (i.e., at two-thirds of the radial distance), wood SG differed significantly from the true cross-sectional mean SG, whereas at two-thirds of the radial distance, the wood SG did not differ significantly from the tree mean SG for a group of 128 tropical trees and 25 temperate trees that had been sampled bark to pith. Overall, the method shows promise in that wood SG of a tree may be estimated accurately and without bias by boring the tree only to the point of approximation, that is, one-sixth of the trunk diameter. However, boring to one-sixth of the diameter provides an unbiased estimate of SG only if radial variation in SG is a linear function of radial distance. A limitation of the method is that an initial subsample of trees must be bored to determine the pattern of radial variation in a species before the approximation can be applied to other individuals.

TI Assessing the Potential for Log Sort Yards to Improve Financial Viability of Forest Restoration Treatments SO FOREST SCIENCE LA English DT Article DE log sort yard; financial analysis; forest restoration treatment; spatial analysis; residual value ID MONTANA; HAZARD AB Forest restoration and fuel reduction treatments have been widely applied in the western United States with the purpose of reducing the size and intensity of wildfires. However, the low value of small-diameter trees produced from such treatments has partly constrained the ability to treat all the areas identified as being in need of treatments. The objective of this study was to analyze the potential for log sort yards to increase the residual value of forest restoration treatments relative to a standard sort at landing in Ravalli County, Montana. We simulated log handing and transportation under two log sorting scenarios in Ravalli County: sort at landing resulting in two log products and sort at sort yard resulting in seven potential log products. Costs and value recovery in each scenario were estimated, and the residual values were compared. We found that establishment of a log sort yard in Ravalli County could increase the residual value of forest restoration treatments by 5%. However, the benefit of the sort yard varies substantially by the forest type from which logs are harvested and the available volume of and markets for high value products, such as house logs. FOR.

TI Post-fire rill and gully formation, Schultz Fire 2010, Arizona, USA SO GEODERMA LA English DT Article DE Wildfire; Soil erosion; Rills; Gullies; Schultz Fire ID EROSION; SOILS AB The Schultz Fire burned 6100 ha on the eastern slopes of the San Francisco Peaks in northern Arizona. The fire burned between June 20th and 30th, 2010, across moderate to very steep ponderosa pine and mixed conifer watersheds. About 40% of the fire area was classified as high-severity, mostly on mountain slopes greater than 30% and in places exceeding 100%. The upper slopes rise to over 3300 m and are the source for high energy water, coarse sediments, and woody material. A series of flood events beginning in mid-July 2010 initiated erosion that removed substantial soil from the upper slopes of the watersheds. The second event was characterized by a peak rainfall of 24 mm in 10 min. Substantial amounts of soil were eroded out of a newly developed rill and gully system, removing the A horizon and much of the B horizon. Prior to the fire there were no rills or gullies as the soil was protected by a thick 0 horizon. This protective organic layer burned off during the fire leaving the soil exposed to raindrop impact and erosion. The re was widespread occurrence of high severity fire, with some watersheds classified as 70% high severity wildfire. This left most of the soils with moderate to severe water repellency. The development of an extensive rill and gully network fundamentally changed the hydrologic response of the upper portions of every catchment. The intense, short duration rainfall of the 2010 monsoon interacted with slope, water repellency and extensive areas of bare soil to produce flood flows an order of magnitude in excess of flows produced by similar pre-fire rainfall events. The till networks now cover much of the upper slopes and gullies are beginning to cut to bedrock. Sediment delivery to the channel systems is likely to continue unabated for many years and hydrologic response will continue to be flashy. Published by Elsevier B.V.

TI Satellite Irrigation Management Support With the Terrestrial Observation and Prediction System: A Framework for Integration of Satellite and Surface Observations to Support Improvements in Agricultural Water Resource Management SO IEEE JOURNAL OF SELECTED TOPICS IN APPLIED EARTH OBSERVATIONS AND REMOTE SENSING LA English DT Article DE Agriculture; irrigation; remote sensing; soil moisture; water resources; wireless sensor networks; web services ID REFERENCE EVAPOTRANSPIRATION; CROP-EVAPOTRANSPIRATION; ENERGY-BALANCE; NORTH-AMERICA; SHADED AREA; MODEL; REFLECTANCE; CALIFORNIA; CANOPY; COEFFICIENTS AB In California and other regions vulnerable to water shortages, satellite-derived estimates of key hydrologic fluxes can support agricultural producers and water managers in maximizing the benefits of available water supplies. The Satellite Irrigation Management Support (SIMS) project combines NASA's Terrestrial Observation and Prediction System (TOPS), Landsat and MODIS satellite imagery, and surface sensor networks to map indicators of crop irrigation demand and develop information products to support irrigation management and other water use decisions. TOPS-SIMS provides the computing and data processing systems required to support automated, near real-time integration of observations from satellite and surface sensor networks, and generates data and information in formats that are convenient for agricultural producers, water managers, and other end users. Using the TOPS modeling framework to integrate data from multiple sensor networks in near real-time, SIMS currently maps crop fractional cover, basal crop coefficients, and basal crop evapotranspiration. Map products are generated at 30 m resolution on a daily basis over approximately 4 million ha of California farmland. TOPS-SIMS is a fully operational prototype, and a publicly available beta-version of the web interface is being pilot tested by farmers, irrigation consultants, and water managers in California. Data products are distributed via dynamic web services, which support both visual mapping and time-series queries, to allow users to obtain information on spatial and temporal patterns in crop canopy development and water requirements. TOPS-SIMS is an application framework that demonstrates the value of integrating multi-disciplinary Earth observation systems to provide benefits for water resource management.

TI Radiometry of Proximal Active Optical Sensors (AOS) for Agricultural Sensing SO IEEE JOURNAL OF SELECTED TOPICS IN APPLIED EARTH OBSERVATIONS AND REMOTE SENSING LA English DT Article DE Agriculture; optics; optoelectronic devices; radiometry; remote sensing ID VEGETATION INDEXES; PASTURE; REFLECTANCE; CORN AB Over the last decade, portable, active optical sensors (AOS) have become tools in production agriculture both for mapping crops and soils and also for applying agrochemicals. These sensors are often referred to as "proximal" active optical sensors, in recognition of their deployment at sensor-target distances in the order of meters. Unfortunately most users have little understanding of the underlying physics (optics) or construction of these sensors. This paper sets out to document the fundamental electro-optical principles by which these devices operate and to document the mathematical rules governing the use of data produced by these devices. In particular, emphasis is placed on the inverse-square law of optics and how it affects AOS measurements. The basis for utilizing sensor measurements in more complex mathematical functions is also presented, including manipulation of the individual wavelength response data to derive information regarding the distance variation between the sensor and the target.

LEAVES; MORUS-ALBA; POLYPHENOLS; FLAVONOIDS; CAPACITY; RADICALS; EXTRACTS; FRUITS; WINES AB To elucidate the effects of cultivar and harvest month on the phenolic content and antioxidant activity of mulberry leaves, four major phenolics, including chlorogenic acid (ChA), benzoic acid (BeA), rutin (Rut) and astragalin (Ast), were quantified using an HPLC-UV method. Leaves from six mulberry cultivars, collected from April to October, were analyzed. The antioxidant activity of mulberry leaves was assessed by ferric reducing antioxidant power (FRAP), hydroxyl radical scavenging activity (HSA) and superoxide radical scavenging activity (SSA) assays. The results showed that the total values of the four phenolic compounds ranged from 2.3 dry weight (DW) to 4.2 mg/g DW, with ChA being the major compound. The mean total phenol (TP) content of the six cultivars ranged from 30.4 equivalents (GAE) mg/g DW to 44.7 GAE mg/g DW. Mulberry leaves harvested in May had the highest TP content. Moreover, the antioxidant activities of mulberry leaves harvested from April to October differed noticeably. In general, Kq 10 and May were considered to be a better cultivar and harvest month concerning phenolic content and antioxidant activity, respectively.

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

Treating output prices as stochastic, the theoretical formulation measures the impact price variability itself has on risk preferences. Acreage response elasticities are also estimated as a function of prices and price variances using U.S. county-level data for corn, soybean, and wheat producers.

SO JOURNAL OF AGRICULTURAL AND RESOURCE ECONOMICS LA English DT Article DE cohort effects; double hurdle models; generational effects; milk consumption ID FOOD; DEMAND AB U.S. per capita fluid milk consumption has decreased since the 1940s. This study uses data collected between 1977 and 2008 from USDA surveys to investigate whether generational change is a contributing factor. More recent generations are found to consume less whole milk and less lower-fat milk, controlling for their age at the time of the survey and other consumption determinants. These findings underscore the importance of checkoff programs, the National School Lunch Program, and other initiatives that encourage children to consume milk. Our methodology may also be adapted to analyze long-run trends in the consumption of other foods. C1 [Stewart, Hayden; Dong, Diansheng; Carlson, Andrea] Econ Res Serv, USDA, Washington, DC USA.

TI Accuracy of genomic breeding values in multibreed beef cattle populations derived from deregressed breeding values and phenotypes SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE across-breed; beef cattle; genomic selection; molecular breeding value ID GENETIC-RELATIONSHIP INFORMATION; ANGUS CATTLE; SELECTION; TRAITS; PREDICTION; CARCASS; PERFORMANCE; ULTRASOUND; PARAMETERS; IMPACT AB Genomic selection involves the assessment of genetic merit through prediction equations that allocate genetic variation with dense marker genotypes. It has the potential to provide accurate breeding values for selection candidates at an early age and facilitate selection for expensive or difficult to measure traits. Accurate across-breed prediction would allow genomic selection to be applied on a larger scale in the beef industry, but the limited availability of large populations for the development of prediction equations has delayed researchers from providing genomic predictions that are accurate across multiple beef breeds. In this study, the accuracy of genomic predictions for 6 growth and carcass traits were derived and evaluated using 2 multibreed beef cattle populations: 3,358 crossbred cattle of the U. S. Meat Animal Research Center Germplasm Evaluation Program (USMARC_GPE) and 1,834 high accuracy bull sires of the 2,000 Bull Project (2000_BULL) representing influential breeds in the U. S. beef cattle industry. The 2000_BULL EPD were deregressed, scaled, and weighted to adjust for between-and within-breed heterogeneous variance before use in training and validation. Molecular breeding values (MBV) trained in each multibreed population and in Angus and Hereford purebred sires of 2000_BULL were derived using the GenSel BayesC pi function (Fernando and Garrick, 2009) and cross-validated. Less than 10% of large effect loci were shared between prediction equations trained on (USMARC_GPE) relative to 2000_BULL although locus effects were moderately to highly correlated for most traits and the traits themselves were highly correlated between populations. Prediction of MBV accuracy was low and variable between populations. For growth traits, MBV accounted for up to 18% of genetic variation in a pooled, multibreed analysis and up to 28% in single breeds. For carcass traits, MBV explained up to 8% of genetic variation in a pooled, multibreed analysis and up to 42% in single breeds. Prediction equations trained in multibreed populations were more accurate for Angus and Hereford subpopulations because those were the breeds most highly represented in the training populations. Accuracies were less for prediction equations trained in a single breed due to the smaller number of records derived from a single breed in the training populations. C1 [Thallman, R. M.; Keele, J.

Molecular breeding values for Angus cattle have been developed by IGENITY, Pfizer Animal Genetics, and a collaboration between researchers from Iowa State University and the University of Missouri-Columbia (ISU/UMC). The U. S. Meat Animal Research Center (USMARC; Clay Center, NE) has also developed MBV for 16 cattle breeds using 2 multibreed populations, the Germplasm Evaluation (GPE) Program and the 2,000 Bull Project (2K(ALL)), and 2 single breed subpopulations of the 2,000 Bull Project, Angus (2K(AN)) and Hereford (2K(HH)). In this study, these MBV were assessed relative to commercial ranch EBV estimated from the progeny phenotypes of Angus bulls naturally mated in multisire breeding pastures to commercial cows: 121 for USMARC MBV, 99 for ISU/UMC MBV, and 29 for IGENITY and Pfizer MBV (selected based on number of progeny carcass records). Five traits were analyzed: weaning weight (WW), HCW, marbling score (MS), rib-eye muscle area (RE), and, for IGENITY and Pfizer only, feedlot ADG. The average accuracies of MBV across traits were 0.38 +/- 0.05 for IGENITY, 0.61 +/- 0.12 for Pfizer, 0.46 +/- 0.12 for ISU/UMC, 0.16 +/- 0.04 for GPE, 0.26 +/- 0.05 for 2K(ALL), 0.24 +/- 0.04 for 2K(AN), and 0.02 +/- 0.12 for 2K(HH). Angus-based MBV (IGENITY, Pfizer, ISU/UMC, and 2K(AN)) explained larger proportions of genetic variance in this population than GPE, 2K(ALL), or 2K(HH) MBV for the same traits. In this data set, IGENITY, Pfizer, and ISU/UMC MBV were predictive of realized performance of progeny, and incorporation of that information into national genetic evaluations would be expected to improve EPD accuracy, particularly for young animals.

TI Effects of reduced panel, reference origin, and genetic relationship on imputation of genotypes in Hereford cattle SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE cattle; genomic; SNP ID PREDICTION AB The objective of this study was to investigate alternative methods of designing and using reduced SNP panels for imputing SNP genotypes. Two purebred Hereford populations, an experimental population known as Line 1 Hereford (L1, n = 240) and registered Hereford with American Hereford Association (AHA, n = 311), were used. Using different reference samples of 62 to 311 animals with 39,497 SNP on 29 autosomes and study samples of 57 or 62 animals for which genotypes were available for similar to 2,600 SNP (reduced panels), imputations were performed to predict the other similar to 36,900 loci that had been masked. An imputation package, including LinkPHASE and DAGPHASE, was used for imputation. Four reduced panels differing in minor allele frequency (MAF) and marker spacing were evaluated. Reduced panels included every 15th SNP across the genome (SNP_space), commercial Illumina Bovine3K Beadchip (SNP_3K), SNP with the highest MAF (SNP_MAF), and SNP with high MAF that were also evenly spaced across the genome (SNP_MS). Imputation accuracy was defined as the correlation of imputed genotypes and real genotypes. Reference samples were either from L1 or AHA. Among animals with genotypes, genetic relationships were estimated based on molecular marker genotypes or pedigree. Reduced panel design, number of animals in the reference sample, reference origin and genetic relationship between animals in the reference, and study samples all affected imputation accuracy (P < 0.001). Across genotyping schemes, imputed genotypes from SNP_MS had the greatest accuracy. A 0.1 increase in average pedigree relationship or average molecular relationship between reference and study samples increased imputation accuracy 10 to 20%. Using reference samples from the L1 population resulted in lower imputation accuracy than using reference samples from the admixed population AHA (P < 0.001). Increasing the number of animals in the reference panel by 100 individuals increased imputation accuracy by 8% when pedigree relationship was used as a covariate and 6% when molecular relationship was used as a covariate. We concluded that imputation accuracy would be increased through optimization of reduced panel design and genotyping strategy. C1 [Huang, Y.; Maltecca, C.; Cassady, J.

Although it has been well established that gustatory and olfactory systems of the mouth and nose provide sensory information to the consumer (in the form of flavor), sweet and bitter taste receptors have recently been identified in the intestinal tract of humans and rodents. It remains possible that sensory information generated in the gut could contribute to the learning process. Thus, a series of experiments was conducted to determine if classical associative learning occurs when the conditional stimulus circumvents oronasal presentation via direct delivery to the gut or peritoneal cavity. Mice receiving an intragastric infusion of 5 mM sodium saccharin immediately followed by LiCl administration demonstrated a significant decrease in preference for 5 mM saccharin in 4 consecutive 23h, 2-bottle preference tests versus water (P = 0.0053). Saccharin was highly preferred in mice receiving intragastric (IG) saccharin only or interperitoneal (i.p.) injection of LiCl only. This reduced preference indicated that mice "tasted" saccharin infused into the gut. However, efforts to replicate with a reduced infusion volume failed to result in decreased preference. To understand if there were alternative pathways for oral detection of infused saccharin, mice received intragastric infusions (5.4 mM) and i.p. injections (10.8 mM) of sodium fluorescein. Fluorescence was observed from the tongues and esophagi of mice infused with volumes of 0.5 mL or more or injected with volumes of 0.25 mL or greater. Interperitoneal injections of 5 mM saccharin in mice resulted in reduced preference for 5 mM saccharin presented orally in 2-bottle preference tests (P = 0.0287). Oral delivery of a 500-fold less concentration of saccharin (0.01 mM) during conditioning resulted in a similar preference expression as shown in the initial IG experiment. These results demonstrate that although compounds may be tasted in the mouth absent of oral contact, associative learning is attenuated. Therefore, intestinal taste receptors are unlikely to participate directly in learning and recognition of foods during foraging events. C1 [Golden, G. J.; Hussey, A. M.; Kimball, B.

In the main study, 6 lactating dairy cows were dosed intraruminally with 240 g/(cow.d) of stearic (SA, control), lauric (LA), or myristic (MA) acid in a replicated 3 x 3 Latin square design trial. Experimental periods were 28 d, and cows were transfaunated between periods. Lauric acid decreased protozoal counts in the rumen by 96% compared with SA and MA (compared with SA, MA had no effect on ruminal protozoa). Whole ruminal contents samples were collected 2, 4, 6, 8, 10, 14, 18, and 24 h after the morning feeding on d 23 of each experimental period, stored frozen, and later composited by cow and period for microbial profile analyses, which involved tag-encoded flexible (FLX) amplicon pyrosequencing to provide diversity analyses of gastrointestinal bacterial, archaeal, and fungal populations of the cattle. The LA treatment, either directly or through its effect on protozoa, had a profound effect on the microbial ecology of the rumen. Ruminal populations of Prevotella, Bacteroides, and Enterorhabdus were decreased (P = 0.04 to P < 0.001) by more than 2-fold in LA treatments compared with SA, and Clostridium populations were decreased (P = 0.01) in LA-compared with MA-treated cows. The proportion of Ruminococcus was not affected by treatment, although the LA treatment had the least proportion of Ruminococcus. Proportions of Eubacterium, Butyrivibrio, Olsenella, and Lactobacillus genera were increased (P = 0.03 to 0.01) by LA compared with MA or SA. The LA treatment, possibly through its effect on protozoa physically associated with archaea, resulted in an increase (P = 0.01) in the archaeal methanogenic genus Methanosphaera and a decrease (P = 0.01) in Methanobrevibacter. Few changes in fungal populations caused by treatment were detected. Collectively, results indicate that LA, either through antiprotozoal or direct antimicrobial effects, altered bacterial and archaeal populations in the rumen of dairy cows, but effects on fungal populations were not clear.

TI A comparison of the metabolism of the abortifacient compounds from Ponderosa pine needles in conditioned versus naive cattle SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE agathic acid; cattle; isocupressic acid; juniper bark; ponderosa pine needles rumen culture ID ISOCUPRESSIC ACID; BEEF-COWS; INGESTION; SAGEBRUSH; ABORTION; SHEEP AB Isocupressic acid (ICA) is the abortifacient compound in ponderosa pine (Pinus ponderosa L.) needles, which can cause late-term abortions in cattle (Bos taurus). However, cattle rapidly metabolize ICA to agathic acid (AGA) and subsequent metabolites. When pine needles are dosed orally to cattle, no ICA is detected in their serum, whereas AGA is readily detected. Recent research has demonstrated that AGA is also an abortifacient compound in cattle. The observation has been made that when cattle are dosed with labdane acids for an extended time, the concentration of AGA in serum increases for 1 to 2 d but then decreases to baseline after 5 to 6 d even though they are still being dosed twice daily. Therefore, in this study we investigated whether cattle conditioned to pine needles metabolize ICA, and its metabolites, faster than naive cattle. Agathic acid was readily detected in the serum of naive cattle fed ponderosa pine needles, whereas very little AGA was detected in the serum of cattle conditioned to pine needles. We also compared the metabolism of ICA in vitro using rumen cultures from pine-needle-conditioned and naive cattle. In the rumen cultures from conditioned cattle, AGA concentrations were dramatically less than rumen cultures from naive cattle. Thus, an adaptation occurs to cattle conditioned to pine needles such that the metabolism AGA by the rumen microflora is altered. C1 [Welch, K. D.; Gardner, D. R.; Pfister, J. A.; Panter, K.

Twenty-four lambs (initial BW 43.8 +/- 4.4 kg) were randomly divided into 4 groups for a 90-d trial. One treatment group (FLX) was fed 136 g/d of nontreated ground flaxseed; another treatment group (FLXT1) was fed 136 g/d of flaxseed treated to protect a-linolenic acid (ALA) from microbial hydrogenation; a third treatment group (FLXT2) was fed 136 g/d of a second treated flaxseed; and a fourth treatment group (CNTL) was fed corn and soybean meal with similar CP and DE levels as the other treatments. Intake of treated flaxseed raised plasma triacylglycerol concentrations of ALA more (P < 0.01) than intake of nontreated flaxseed did, but there was no difference (P = 0.65) in ALA increase between FLXT1 and FLXT2. Intake of treated flaxseed increased (P <= 0.05) muscle phospholipid ALA and eicosapentaenoic acid concentrations more than nontreated flaxseed did. There were no differences in muscle phospholipid n-3 concentrations between FLXT1 and FLXT2. Ten yearling steers (initial BW 437 +/- 18 kg) were randomly divided into 2 groups. One group was fed ground flaxseed (0.05% of steer BW/d; FLX; n = 5) and a second group was fed treated flaxseed at the same rate (FLXT; n = 5). The 175-d trial was divided into 2 periods: high roughage, low concentrate period followed by high concentrate, low roughage period. Steers were fed rations that were formulated to be isonitrogenous, isocaloric, and isolipidic. There was no difference (P = 0.37) in increase of ALA in blood plasma of FLX and FLXT groups by the end of the first period. However, FLXT had 16% greater (P = 0.003) concentration of ALA in their plasma during the second period. Muscle phospholipid n-3 FA were not greater (P >= 0.55) for steers in the FLXT group. Intake of treated flaxseed raised n-3 concentrations in blood and muscle of sheep, and in blood of cattle but did not raise n-3 FA concentrations in muscle of steers. Supplementing the diets of forage-fed lambs with flaxseed treated to reduce hydrogenation of ALA by ruminal microbes can increase concentrations of n-3 FA in the muscle of lambs. C1 [Kronberg, S.

A partial life cycle assessment (LCA) was conducted using the Integrated Farm System Model (IFSM) to estimate GHG and NH3 emissions from representative beef production systems in California. The IFSM is a process-level farm model that simulates crop growth, feed production and use, animal growth, and the return of manure nutrients back to the land to predict the environmental impacts and economics of production systems. Ammonia emissions are determined by summing the emissions from animal housing facilities, manure storage, field applied manure, and direct deposits of manure on pasture and rangeland. All important sources and sinks of methane, nitrous oxide, and carbon dioxide are predicted from primary and secondary emission sources. Primary sources include enteric fermentation, manure, cropland used in feed production, and fuel combustion. Secondary emissions occur during the production of resources used on the farm, which include fuel, electricity, machinery, fertilizer, and purchased animals. The carbon footprint is the net exchange of all GHG in carbon dioxide equivalent (CO(2)e) units per kg of HCW produced. Simulated beef production systems included cow-calf, stocker, and feedlot phases for the traditional British beef breeds and calf ranch and feedlot phases for Holstein steers. An evaluation of differing production management strategies resulted in ammonia emissions ranging from 98 +/- 13 to 141 +/- 27 g/kg HCW and carbon footprints of 10.7 +/- 1.4 to 22.6 +/- 2.0 kg CO(2)e/kg HCW. Within the British beef production cycle, the cow-calf phase was responsible for 69 to 72% of total GHG emissions with 17 to 27% from feedlot sources. Holstein steers that entered the beef production system as a by-product of dairy production had the lowest carbon footprint because the emissions associated with their mothers were primarily attributed to milk rather than meat production. For the Holstein system, the feedlot phase was responsible for 91% of the total GHG emission, while the calf-ranch phase was responsible for 7% with the remaining 2% from transportation. This simulation study provides baseline emissions data for California beef production systems and indicates where mitigation strategies can be most effective in reducing emissions.

TI Growth-promoting technologies decrease the carbon footprint, ammonia emissions, and costs of California beef production systems SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE ammonia; beef cattle; carbon footprint; farm simulation; greenhouse gas; mitigation ID DAIRY PRODUCTION SYSTEMS; CARCASS CHARACTERISTICS; ENVIRONMENTAL-IMPACT; FEEDLOT PERFORMANCE; MEAT QUALITY; AGONISTS; STRATEGIES; CATTLE AB Increased animal performance is suggested as one of the most effective mitigation strategies to decrease greenhouse gas (GHG) and ammonia (NH3) emissions from livestock production per unit of product produced. Little information exists, however, on the effects of increased animal productivity on the net decrease in emission from beef production systems. A partial life cycle assessment (LCA) was conducted using the Integrated Farm System Model (IFSM) to estimate GHG and NH3 emissions from representative beef production systems in California that use various management technologies to enhance animal performance. The IFSM is a farm process model that simulates crop growth, feed production, animal performance, and manure production and handling through time to predict the performance, economics, and environmental impacts of production systems. The simulated beef production systems compared were 1) Angus-natural, with no use of growth-enhancing technologies, 2) Angus-implant, with ionophore and growth-promoting implant (e. g., estrogen/trenbolone acetate-based) application, 3) Angus-beta 2-adrenergic agonists (BAA; e. g., zilpaterol), with ionophore, growth-promoting implant, and BAA application, 4) Holstein-implant, with growth implant and ionophore application, and 5) Holstein-BAA, with ionophore, growth implant, and BAA use. During the feedlot phase, use of BAA decreased NH3 emission by 4 to 9 g/kg HCW, resulting in a 7% decrease in NH3 loss from the full production system. Combined use of ionophore, growth implant, and BAA treatments decreased NH3 emission from the full production system by 14 g/kg HCW, or 13%. The C footprint of beef was decreased by 2.2 kg carbon dioxide equivalent (CO(2)e)/kg HCW using all the growth-promoting technologies, and the Holstein beef footprint was decreased by 0.5 kg CO(2)e/kg HCW using BAA. Over the full production systems, these decreases were relatively small at 9% and 5% for Angus and Holstein beef, respectively. The growth-promoting technologies we evaluated are a cost-effective way to mitigate GHG and NH3 emissions, but naturally managed cattle can bring a similar net return to Angus cattle treated with growth-promoting technologies when sold at an 8% greater premium price.

Two eddy covariance micrometeorological stations were used to test the hypothesis that fine-scale variations in the physical properties of the site result in significant variation in the surface energy balance. Through a comparative analysis of the flux measurements, it was found that statistically significant variations in the sensible, latent and soil heat fluxes were present at the study site. These variations were linked to small changes in the near-surface soil moisture content and leaf area index. The results of this study suggest there may be substantial uncertainty surrounding a single point measurement when it is used to represent the exchange of heat and moisture over a large area. This uncertainty must be considered when using in-situ measurements to evaluate remote sensing products or numerical models. Published by Elsevier Ltd. C1 [Alfieri, J.

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

AB Oplostomus haroldi Witte belongs to a unique genus of afro-tropical scarabs that have associations with honey bee colonies, from which they derive vital nutrients. Although the attributes of the honey bee nest impose barriers to communication among nest invaders, this beetle still is able to detect conspecific mates for reproduction. Here, we show, through behavioral studies, that cuticular lipids serve as mate discrimination cues in this beetle. We observed five steps during mating: arrestment, alignment, mounting, and copulation, and a post-copulatory stage, lasting similar to 40-70 % of the total mating duration, that suggested mate guarding. Chemical analysis identified the same nine straight-chain alkanes (C-23-C-31), six methyl-branched alkanes (6), and five mono-unsaturated alkenes in the cuticular lipids of both sexes. Methyl alkanes constituted the major component (46 %) of male cuticular lipids, while mono-unsaturated alkenes were most abundant (53 %) in females. (Z)-9-Pentacosene was twice as abundant in females than in males, and similar to 20 fold more concentrated in beetles than in worker bees. In mating assays, (Z)-9-pentacosene elicited arrestment, alignment, and mounting, but not copulation, by male beetles. These results represent the first evidence of a contact sex pheromone in a scarab beetle. Such contact pheromones may be an essential, cryptic mechanism for arthropods associated with eusocial insects. C1 [Fombong, Ayuka T.; Torto, Baldwyn] Int Ctr Insect Physiol & Ecol, Nairobi, Kenya.

Standard industry practice is to roast peanuts to a specific surface color (Hunter L-value) for a given application; however, equivalent surface colors can be attained using different roast temperature/time combinations, which could affect product quality. To investigate this potential, runner peanuts from a single lot were systematically roasted using 5 roast temperatures (147, 157, 167, 177, and 187 degrees C) and to Hunter L-values of 53 +/- 1, 48.5 +/- 1, and 43 +/- 1, corresponding to light, medium, and dark roasts, respectively. Moisture contents (MC) ranged from 0.41% to 1.70% after roasting. At equivalent roast temperatures, MC decreased as peanuts became darker; however, for a given color, MC decreased with decreasing roast temperature due to longer roast times required for specified color formation. Initial total tocopherol contents of expressed oils ranged from 164 to 559 mu g/g oil. Peanuts roasted at lower temperatures and darker colors had higher tocopherol contents. Glucose content was roast color and temperature dependent, while fructose was only temperature dependent. Soluble protein was lower at darker roast colors, and when averaged across temperatures, was highest when samples were roasted at 187 degrees C. Lysine content decreased with increasing roast color but was not dependent on temperature. MC strongly correlated with several components including tocopherols (R-2 = 0.67), soluble protein (R-2 = 0.80), and peak force upon compression (R-2 = 0.64). The variation in characteristics related to roast conditions is sufficient to suggest influences on final product shelf life and consumer acceptability.

TI Quantification of heterosubtypic immunity between avian influenza subtypes H3N8 and H4N6 in multiple avian host species SO JOURNAL OF GENERAL VIROLOGY LA English DT Article ID MALLARDS ANAS-PLATYRHYNCHOS; WILD BIRDS; A VIRUSES; INDIVIDUAL VARIATION; INFECTION; PROTECTION; CHALLENGE; EVOLUTION; CHICKENS; ECOLOGY AB Low-pathogenicity avian influenza virus (LPAIV) can lead to epizootics that cause economic losses in poultry or the emergence of human-infectious strains. LPAIVs experience a complex immunity landscape as they are endemic in numerous host species, and many antigenically distinct strains co-circulate. Prevention and control of emergence of detrimental strains requires an understanding of infection/transmission characteristics of the various subtypes in different hosts, including interactions between subtypes. In order to develop analytical frameworks for examining control efficacy, quantification of heterosubtypic immunity interactions is fundamental. However, these data are scarce, especially for wild avian subtypes in natural hosts. Consequently, in this study, three host species (mallards, quail and pheasants) were infected with two LPAIV subtypes isolated from wild birds: H3N8 and H4N6. The recovered hosts were also reinfected with the alternate subtype to measure the effects of heterosubtypic immunity. Oropharyngeal and cloacal swabs were collected and viral RNA load was quantified by real-time RT-PCR. For secondary infections in recovered hosts, peak viral load was up to four orders of magnitude lower and shedding length was up to 4 days shorter. However, both the magnitude and presence of heterosubtypic immunity varied across specific host species/subtype combinations. Using a mathematical model of virus replication, the variation in virus replication dynamics due to host individuals was quantified. It was found that accounting for individual heterogeneity is important for drawing accurate conclusions about treatment effects. These results are relevant for developing epidemiological models to inform control practices and for analysing virus replication data. C1 [VanDalen, K. K.; Mooers, N. L.; Ellis, J. W.; Sullivan, H.

To estimate the extent of genomic reassortment in influenza viruses circulating in North American swine, we performed a phylogenetic analysis of 139 whole-genome viral sequences sampled during 1998-2011 and representing seven antigenically distinct viral lineages. The highest amounts of reassortment were detected between the H3 and the internal gene segments (PB2, PB1, PA, NP, M and NS), while the lowest reassortment frequencies were observed among the H1 gamma, H1pdm and neuraminidase segments, particularly N1. Less reassortment was observed among specific haemagglutinin neuraminidase combinations that were more prevalent in swine, suggesting that some genome constellations may be evolutionarily more stable.

TI Detection of PrPSc in peripheral tissues of clinically affected cattle after oral challenge with bovine spongiform encephalopathy SO JOURNAL OF GENERAL VIROLOGY LA English DT Article ID IN-VITRO AMPLIFICATION; MISFOLDING CYCLIC AMPLIFICATION; CREUTZFELDT-JAKOB-DISEASE; NERVOUS-SYSTEM; PRION PROTEIN; INFECTIOUS PRIONS; BSE INFECTIVITY; SCRAPIE; BRAIN; MICE AB Bovine spongiform encephalopathy (BSE) is a fatal neurodegenerative prion disease that mainly affects cattle. Transmission of BSE to humans caused a variant form of Creutzfeldt Jakob disease. Following infection, the protease-resistant, disease-associated isoform of prion protein (PrPSc) accumulates in the central nervous system and in other tissues. Many countries have defined bovine tissues that may contain prions as specified risk materials, which must not enter the human or animal food chains and therefore must be discarded. Ultrasensitive techniques such as protein misfolding cyclic amplification (PMCA) have been developed to detect PrPSc when present in minuscule amounts that are not readily detected by other diagnostic methods such as immunohistochemistry or Western blotting. This study was conducted to determine when and where PrPSc can be found by PMCA in cattle orally challenged with BSE. A total of 48 different tissue samples from four cattle infected orally with BSE at various clinical stages of disease were examined using a standardized PMCA protocol. The protocol used brain homogenate from bovine PrP transgenic mice (Tgbov XV) as substrate and three consecutive rounds of PMCA. Using this protocol, PrPSc was found in the brain, spinal cord, nerve ganglia, optic nerve and Peyer's patches. The presence of PrPSc was confirmed in adrenal glands, as well as in mesenteric lymph nodes a finding that was reported recently by another group. Interestingly, additional positive results were obtained for the first time in the oesophagus, abomasum, rumen and rectum of clinically affected cattle.

To understand the load transfer in the walls, this study used a finite-element model WALL2D, which is able to model individual wall components, including framing members, sheathing panels, oriented panel-frame nailed connections, framing connections, hold-down connections, and strap connections for reinforcing the corners of openings. The various wall models were validated through laboratory testing of 12 full-scale 2.44 x 3.66 m (8' x 12') shear wall configurations, which included a variety of opening types and sizes. At the wall design load level, the predicted strap forces around openings also agreed well with the test results, in contrast with four simplified analytical methods commonly used in designing shear walls with openings detailed for FTAO. This wall model thus presents a useful tool to check the accuracy of the simplified methods and develop a better understanding of the behavior of wood-frame shear walls with openings.

The bioassay consisted of an attractive source surrounded by a grid of 16 septa containing a volatile candidate aerial repellent, compared with an attractive source without such a grid. The attractive source was a Centers for Disease Control and Prevention light trap supplemented with carbon dioxide. Significant sources of variation included weather, position, and the differential response of mosquito species. Despite these sources of variation, significant repellent responses were obtained for catnip oil, E,Z-dihydronepetalactone, and DEET. C1 [Chauhan, K. R.; Aldrich, J. R.; McCardle, P. W.; White, G.

A large spray block was targeted with aerial spray treatments of etofenprox in order to create a gradient in both spray concentration and mortality. Spray concentrations were measured using rotary impactors, which were coupled with caged bioassays. Measured spray concentrations were corrected for sampler collection efficiencies, which ranged from 55% to 15%. The corrected spray concentrations were then used to estimate the spray levels inside the bioassay cages. Given the cage type used (Townzen type) and wind speeds occurring during the spray trials (2-4 m/sec), concentrations inside of the bioassay cage ranged from 65% to 68% of that measured within the spray block. Not correcting for the combination of sampler collection efficiency and cage interference, underestimated spray concentration levels inside the cages were 76-90%. Correcting field-measured data allows not only better comparisons between differing studies, but can also provide better estimates of caged insect mortality versus actual spray concentration exposure levels.

Sweet potato virus C (SPVC), Sweet potato virus G (SPVG) and/or Sweet potato virus 2 (SPV2), are involved in sweet potato virus disease complexes worldwide. Identification and detection of these viruses are complicated by high similarity among their genomic sequences, frequent occurrence as mixed infections and low titer in many sweet potato cultivars. A one-tube multiplex reverse transcription-PCR (mRT-PCR) assay was developed for simultaneous detection and differentiation of SPFMV, SPVC, SPVG and SPV2. Four specific forward primers unique to each virus and one reverse primer based on the region conserved in all four viruses were selected and used in the assay. The mRT-PCR assay was optimized for primer concentration and cycling conditions. It was tested using sweet potato plants infected naturally with one to four target viruses and then evaluated using field samples collected from southwestern China. The mRT-PCR assay is reliable and sensitive as a simple, rapid and cost-effective method to detect these pathogens in sweet potato. This assay will be useful to quarantine and certification programs and virus surveys when large numbers of samples are tested. Published by Elsevier B.V.

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

Both the crude phenolic extract and biochanin A, an isoflavonoid component of the extract, suppress growth of Clostridium sticklandii, a bovine, Gram-positive, ruminal hyper-ammonia producing bacterium (HAB). The purpose of this study was to determine if other components of red clover extract contributed to its anti-HAB activity. Extracts of the Kenland cultivar of red clover, collected 0 h and 24 h after cutting, were separated by normal-phase thin-layer chromatography (TLC) in either ethyl acetate-hexanes (9:1, v/v) or ethyl acetate-methanol (4:1, v/v). Bands on TLC plates were assayed by either overlaying the plates with agar seeded with C. sticklandii, or setting the excised bands face-down onto plates of bacteria-seeded agar. Biochanin A inhibited C. sticklandii growth on TLC plates when as little as 8 nmol was present in the extract. An antimicrobial band, seen in a previous bioassay, was not found, suggesting that this second compound may be more labile than biochanin A.

Although much research has been done to assess HWA impacts on ecosystem processes and vegetation structure, few researchers have examined community-level changes in highly infested forest stands. Here we assess the impact of Eastern Hemlock mortality on vegetation and invertebrate diversity and community structure by comparing low-impact (healthy) stands and stands heavily impacted by HWA. We sampled the vegetative and invertebrate diversity of 8 sites (4 low impact and 4 high impact) in the summer and fall of 2008. We found a shift in the understory plant community and the canopy and subcanopy arthropod communities. Herbaceous plant species richness was significantly higher at high-impact sites, with Betula lenta (Black Birch) being the most common woody species. Overall, forest invertebrate community diversity (measured using the Shannon-Weaver diversity index) was greater in high- versus low-impact sites. Of the 21 indicator species significantly associated with a given forest type, 14 and 7 species were associated with high- and low-impact forests, respectively. Variation in arthropod community structure was driven by above-ground differences; ground-level arthropod community composition did not differ between high- and low-impact sites. These results demonstrate some of the biodiversity impacts that can result from the invasion of an exotic insect into forested systems.

TI "Island" Attributes and Benthic Macroinvertebrates of Seasonal Forest Pools SO NORTHEASTERN NATURALIST LA English DT Article ID FRESH-WATER POOLS; SPECIES RICHNESS; TEMPORARY POOLS; COMMUNITY STRUCTURE; VERNAL POOLS; CRUSTACEAN ASSEMBLAGES; EQUILIBRIUM-THEORY; SPATIAL-PATTERNS; HABITAT DURATION; PONDS AB Seasonal forest pools (SFPs), also known as woodland vernal pools or simply vernal pools, are common throughout the forests of the northeastern United States. SFPs are inundated during all or part of the period between late fall of one year and late spring to mid-summer of the subsequent year. The pools dry every year or at sufficient frequency to preclude the establishment of fish populations, are preferred breeding habitat for a number of amphibian species, and support a rich, diverse, and abundant macroinvertebrate community. These pools exist as aquatic "islands" in a "sea" of forest, and occur over a range of sizes, degrees of isolation, and hydroperiod lengths. As islands, pool area and isolation should affect the composition of biotic communities. The hydroperiod of ephemeral wetlands has been considered a third "island" attribute and is also known to affect biotic composition. We surveyed aquatic, benthic macroinvertebrates (BMIs) for two years using leaf-packs in 24 SFPs, representing a broad range of surface areas, inter-pool distances (isolation), and hydroperiods. Nearly 35,000 specimens of 76 taxa were enumerated from 198 leaf-pack samples. Chironomidae and Oligochaeta were the most abundant and most common taxa. BMI richness and diversity were positively, but weakly, related to maximum pool surface area, but not to pool isolation. The same results were found for permanent resident and predator taxa. BMI richness and diversity were positively related with pool hydroperiod, as reported from numerous other studies of ephemeral aquatic habitats.

Our data show that invasive P. australis utilizes a greater depth range than native graminoids (90% within the top 70 cm and top 20 cm, respectively). We corroborate prior anecdotal observations and provide further evidence illustrating the potential for this invasive plant to access resources (i.e., water and nutrients) at depths greater than the native species with which it competes.

TI Expression of allelopathy in the soil environment: soil concentration and activity of benzoxazinoid compounds released by rye cover crop residue SO PLANT ECOLOGY LA English DT Article DE BOA; MBOA; Secale cereale; Lactuca sativa; Amaranthus hybridus ID SECALE-CEREALE L.; DEGRADATION-PRODUCTS; ALLELOCHEMICALS; GROWTH; PHYTOTOXICITY; MANAGEMENT; CULTIVAR; ANALOGS; DIBOA; SAR AB Rye (Secale cereale L.) residue is known to suppress weeds in agronomic environments and to produce benzoxazinoid (BX) compounds which are phytotoxic. Experiments were conducted to determine the duration of indicator plant inhibition and BX soil concentrations in response to field incorporated or surface rye residue. Surface rye residue was highly inhibitory to lettuce (Lactuca sativa L.) and smooth pigweed (Amaranthus hybridus L.) throughout an experimental period of 4 weeks, whereas soil removed from beneath residue and assayed in pots had little phytotoxicity, suggesting that physical rather than chemical mechanisms were involved. Incorporated residue inhibited lettuce and pigweed for approximately 2 weeks after incorporation, which corresponded to the period when elevated BX levels were detected in soil, suggesting potential allelopathy. The most toxic BX compounds, APO, DIBOA, and DIMBOA, were present at relatively low levels, whereas the less toxic compounds, BOA and MBOA, and the non-toxic compounds, HBOA and HMBOA, were the predominant BX species in amended soils. When the benzoxazolinones BOA and MBOA were exogenously added to soils to maintain extractable levels of up to 10 mu g g(-1) soil (100-500 times higher than measured BX in field soils), no significant inhibition of pigweed plants was observed. This result indicated that the observed association between the duration of plant inhibition and BX from incorporated rye was not causal, and that other compounds released with similar dynamics were likely responsible. This approach provides a sound basis for demonstrating the presence of allelopathy in natural or managed ecosystems.

Here, we compare genome features of 18 members of this class, including 6 necrotrophs, 9 (hemi)biotrophs and 3 saprotrophs, to analyze genome structure, evolution, and the diverse strategies of pathogenesis. The Dothideomycetes most likely evolved from a common ancestor more than 280 million years ago. The 18 genome sequences differ dramatically in size due to variation in repetitive content, but show much less variation in number of (core) genes. Gene order appears to have been rearranged mostly within chromosomal boundaries by multiple inversions, in extant genomes frequently demarcated by adjacent simple repeats. Several Dothideomycetes contain one or more gene-poor, transposable element (TE)-rich putatively dispensable chromosomes of unknown function. The 18 Dothideomycetes offer an extensive catalogue of genes involved in cellulose degradation, proteolysis, secondary metabolism, and cysteine-rich small secreted proteins. Ancestors of the two major orders of plant pathogens in the Dothideomycetes, the Capnodiales and Pleosporales, may have had different modes of pathogenesis, with the former having fewer of these genes than the latter. Many of these genes are enriched in proximity to transposable elements, suggesting faster evolution because of the effects of repeat induced point (RIP) mutations. A syntenic block of genes, including oxidoreductases, is conserved in most Dothideomycetes and upregulated during infection in L. maculans, suggesting a possible function in response to oxidative stress.

This study, conducted in a 2.5-km-long shallow floodplain severed meander backwater adjacent to the Coldwater River in Tunica County, Mississippi, USA, compared water quality during a late summer 30-day artificial flooding period with 28-day pre-flood and 26-day post-flood periods. Flooding was simulated by pumping 0.22 to 0.35?m3?s-1 from the river into the upstream portion of the backwater. In situ parameters (temperature, pH, dissolved oxygen, conductivity and fluorescent chlorophyll) were measured every 30?min at one site within the backwater. Solids (dissolved and suspended) and nutrients (phosphorus and nitrogen) were measured at three sites in the backwater and in the river every 3 to 5?days. Decreases in the amplitude of temperature, dissolved oxygen and pH diel cycles within the backwater were observed during flooding. Changes in patterns of solids and nutrients were also associated with flooding. Complex patterns in phosphorus and nitrogen emerged as a result of utilization by autotrophs (measured as chlorophyll) and seasonal changes. Artificial flooding in a shallow floodplain water body stabilized and improved water quality for aquatic biota and is a viable method for habitat rehabilitation in these systems.

Thirty samples from the litter/duff (LD) and the top 5 cm of the mineral soil (MS) were collected from five 5-ha burn units (6 plots per experimental unit) before and immediately after low-intensity prescribed fires, where maximum fire temperatures varied from <79 to 316 degrees C. A split-plot ANOVA and multi-response permutation procedures (MRBP) were utilized to assess the effects of burn treatment (pre- or post-fire) and seed bank layer (LD and MS) on the diversity and density of the buried seed bank. An average of 471 emergents/m(2) was observed in the buried seed bank comprising 133 identifiable taxa. No differences in total seed-bank density, Shannon-Weiner's diversity index (H'), or overall species composition between pre- and post-fire sampling or between the LD and MS layers were observed. Species richness (S) of the seed bank, however, was slightly greater pre-fire than post-fire, regardless of layer. Similarity, as defined by Sorenson's index, of species common to the seed bank and aboveground forest understory was low, with a slight increase in Sorenson's index observed during post-fire sampling of the seed bank and aboveground vegetation. Although we observed only negligible effects of a once-applied, low-intensity prescribed fire on the buried seed bank, the effects of a low-intensity prescribed fire management regime-one that involves repeated low intensity burns-on the buried seed bank are unknown and should be a focus of future studies across mixed-oak forests in the eastern US.

We evaluated annual patterns of basal-area and height growth of coast Douglas-fir (Pseudotusga menziesii var. menziesii (Mirb.) Franco) seedlings from four seed sources that were planted in four diverse environments as part of the Douglas-fir Seed-Source Movement Trial. Stem diameters and heights were measured periodically during the 2010 growing season on 16 open-pollinated families at each study installation. Stem diameters were measured on a subset of trees with electronic dendrometers during the 2010 and 2011 growing seasons. Trees from the four seed sources differed in phenology metrics that described the timing of basal-area and height-growth initiation, growth cessation and growth rates. Differences in the height-growth metrics were generally larger than differences in the basal-area growth metrics and differences among installations were larger than differences among seed sources, highlighting the importance of environmental signals on growth phenology. Variations in the height- and basal-area growth metrics were correlated with different aspects of the seed-source environments: precipitation in the case of height growth and minimum temperature in the case of basal-area growth. The detailed dendrometer measurements revealed differences in growth patterns between seed sources during distinct periods in the growing season. Our results indicate that multiple aspects of growth phenology should be considered along with other traits when evaluating adaptation of populations to future climates.

The 13-member Stony Brook University (SBU) ensemble at 0000 UTC is combined with the 21-member National Centers for Environmental Prediction (NCEP) Short-Range Ensemble Forecast (SREF) system at 2100 UTC. The ensemble is verified using 2-m temperature and 10-m wind speed for the 2007-09 warm seasons, and for subsets of days with high ozone and high fire threat. The impacts of training period, bias-correction method, and BMA are explored for these potentially hazardous weather events using the most recent consecutive (sequential training) and most recent similar days (conditional training). BMA sensitivity to the selection of ensemble members is explored. A running mean difference between forecasts and observations using the last 14 days is better at removing temperature bias than is a cumulative distribution function (CDF) or linear regression approach. Wind speed bias is better removed by adjusting the modeled CDF to the observation. High fire threat and ozone days exhibit a larger cool bias and a greater negative wind speed bias than the warm-season average. Conditional bias correction is generally better at removing temperature and wind speed biases than sequential training. Greater probabilistic skill is found for temperature using both conditional bias correction and BMA compared to sequential bias correction with or without BMA. Conditional and sequential BMA results are similar for 10-m wind speed, although BMA typically improves probabilistic skill regardless of training.

Enhanced erosion leads to a reduction in soil fertility and the post-fire mobilisation of soil and associated emissions of dust represent a significant concern for ecosystem management and risk assessment. Here we investigate the temporal change of aeolian activity following a wildfire within both a managed grassland and an adjacent shrub encroached grassland at the Cimarron National Grassland, KS, USA. Our results indicate that, even though the grassland and shrub encroached grassland sites exhibit comparable aeolian activity soon after the fire, the duration of the post-disturbance period of aeolian activity (or "window of disturbance") is shorter in the case of grassland than in the case of shrub encroached grassland. The degree of post-fire aeolian transport and its attenuation with time is strongly affected by the antecedent vegetation type. These findings have implications for management of semi-arid grasslands under both changing vegetation types (shrub encroachment) and disturbance (fire) regimes. (C) 2011 Elsevier B.V.

TI Improving evapotranspiration simulations in the CERES-Maize model under limited irrigation SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE Crop model; Evaporation and transpiration; Deficit irrigation; Crop coefficient; Water production functions ID SOIL-WATER BALANCE; LEAF-AREA INDEX; DEFICIT IRRIGATION; CORN; YIELD; MANAGEMENT; TRANSPIRATION; ENVIRONMENT; SCENARIOS; STRESS AB Limitations on water resources for agriculture in places such as Colorado, USA, have caused farmers to consider limited irrigation as an alternative to full irrigation practices, where the crop is intentionally stressed during specific growth stages in an effort to maximize yield per unit water consumed, or evapotranspiration (ET). While crop growth models such as CERES-Maize provide the ability to evaluate numerous management scenarios without the costs associated with multiyear field experiments, recent studies have shown that CERES-Maize performs well under full irrigation but overestimates ET of corn under limited irrigation management. The primary objective of this study was to improve CERES-Maize ET simulation under limited irrigation management while maintaining accuracy of other important model output responses. Field experiments with corn were performed in northern Colorado, USA from 2006 to 2010, where four replicates each of full (ET requirement supplied by irrigation throughout the season) and limited (no irrigation before the V12 growth stage unless necessary for emergence, then full irrigation afterwards) irrigation treatments were analyzed. The local sensitivity of model input parameters affecting ET was evaluated, prompting changes to the model code with a new dynamic crop coefficient (K-CD) as a function of the crop leaf area index. The modified CERES-Maize model more accurately represented ET under full and limited irrigation, for example reducing late-season ET potential from a plant with reduced canopy and more closely matched FAO-56 crop coefficient curves under full irrigation. Using the limited irrigation data for evaluation, the modified model showed significant decreases in model error for seasonal cumulative ET (root mean square deviation RMSD from 80.9 mm to 49.9 mm) and water productivity (RMSD from 5.97 kg ha(-1) mm(-1) to 2.86 kg ha(-1) mm(-1)) as compared to the original model. The modified model was subsequently applied to several hypothetical irrigation management strategies, indicating that reducing weekly vegetative stage water applications from 20 mm to 2.5 mm can increase simulated water productivity by over 15%. While these synthetic water production functions may not be feasible in a production field with natural climate variability, the modified ET model indicates promise for limited irrigation management increasing water productivity.

De novo synthesis is the main source of ornithine for citrulline production in neonatal pigs. Am J Physiol Endocrinol Metab 303: E1348-E1353, 2012. First published October 16, 2012; doi:10.1152/ajpendo.00399.2012.-Citrulline is an amino acid synthesized in the gut and utilized for the synthesis of the conditionally essential amino acid arginine. Recently, the origin of the ornithine utilized for citrulline synthesis has become a matter of discussion. Multiple physiological factors may have contributed to the differences found among different researchers; one of these is the developmental stage of the subjects studied. To test the hypothesis that during the neonatal period de novo synthesis is the main source of ornithine for citrulline synthesis, neonatal piglets were infused intravenously or intragastrically with [U-C-13(6)] arginine, [U-C-13(5)] glutamine, or [U-C-13(5)] proline during the fasted and fed periods. [ureido-N-15] citrulline and [H-2(2)] ornithine were infused intravenously for the entire infusion protocol. During fasting, plasma proline (13%) and ornithine (19%) were the main precursors for citrulline synthesis, whereas plasma arginine (62%) was the main precursor for plasma ornithine. During feeding, enteral (27%) and plasma (12%) proline were the main precursors for the ornithine utilized in the synthesis of citrulline, together with plasma ornithine (27%). Enteral proline and glutamine were utilized directly by the gut to produce ornithine utilized for citrulline synthesis. Arginine was not utilized by the gut, which is consistent with the lack of arginase activity in the neonate. Arginine, however, was the main source (47%) of plasma ornithine and in this way contributed to citrulline synthesis. In conclusion, during the neonatal period, the de novo pathway is the predominant source for the ornithine utilized in the synthesis of citrulline, and proline is the preferred precursor.

Geospatial frameworks help resolve patterns and trends in production environments (at multiple scales) that may enable improvements in adaptive management strategies which enhance yield, increase whole-farm profitability, and foster sustainable land use. Results from geospatial integration of remotely-sensed cropland (2008-2010) and soil datasets for Maine indicate an estimated 61,900 ha in potato production with 62 % and 27 % on prime farmland (PF) and farmland of statewide importance (FSI), respectively. Geospatial analyses of other agri-environmental indicators indicate close to 85 % of these potato production soils are classified as either "potentially highly erodible" (PHEL) or "highly erodible" (HEL). Therefore, at least 52,300 ha require the highest standards in soil conservation practices. Crop rotation patterns for potato, derived from the time-series geo-referenced datasets, help resolve actual cropping practices and facilitated evaluation of the benefits and economic impacts for select alternate crops.

TI Fire-injured ponderosa pine provide a pulsed resource for bark beetles SO CANADIAN JOURNAL OF FOREST RESEARCH-REVUE CANADIENNE DE RECHERCHE FORESTIERE LA English DT Article ID MIXED-CONIFER FOREST; TREE MORTALITY; NORTHERN ARIZONA; RESIN DEFENSES; SIERRA-NEVADA; OLEORESIN CHARACTERISTICS; RESTORATION TREATMENTS; SURROGATE TREATMENTS; INTERMOUNTAIN WEST; PRESCRIBED FIRES AB Bark beetles can cause substantial mortality of trees that would otherwise survive fire injuries. Resin response of fire-injured northern Rocky Mountain ponderosa pine (Pinus ponderosa Douglas ex P. Lawson & C. Lawson) and specific injuries that contribute to increased bark beetle attack susceptibility and brood production are unknown. We monitored ponderosa pine mortality and resin flow and bark beetle colonization and reproduction following a prescribed fire in Idaho and a wildfire in Montana. The level of fire-caused tree injury differed between the two sites, and the level of tree injury most susceptible to bark beetle attack and colonization also differed. Strip-attacked trees alive 3 years post-fire had lower levels of bole and crown injury than trees mass attacked and killed by bark beetles, suggesting that fire-injured trees were less well defended. Brood production of western pine beetle (Dendroctonus brevicomis LeConte) did not differ between fire-injured and uninjured trees, although mountain pine beetle (Dendroctonus ponderosae Hopkins) brood production was low in both tree types, potentially due to competition with faster developing bark beetle species that also colonized trees. Despite a large number of live trees remaining at both sites, bark beetle response to fire-injured trees pulsed and receded within 2 years post-fire, potentially due to a limited number of trees that could be easily colonized.

TI A major shift to the retention approach for forestry can help resolve some global forest sustainability issues SO CONSERVATION LETTERS LA English DT Article DE Ecologically sustainable forest management; altered logging practices; forest biodiversity conservation; forest ecosystem processes; altered forest policy; ecological forestry ID GREEN-TREE RETENTION; VARIABLE RETENTION; ECOLOGICAL CONSEQUENCES; WORLDS FORESTS; WET FORESTS; BIODIVERSITY; MANAGEMENT; CONSERVATION; HARVEST; LAND AB Approximately 85% of the global forest estate is neither formally protected nor in areas dedicated to intensive wood production (e.g., plantations). Given the spatial extent of unprotected forests, finding management approaches that will sustain their multiple environmental, economic, and cultural values and prevent their conversion to other uses is imperative. The major global challenge of native forest management is further demonstrated by ongoing steep declines in forest biodiversity and carbon stocks. Here, we suggest that an essential part of such managementsupplementing the protection of large reserves and sensitive areas within forest landscapes (e.g., aquatic features)is the adoption of the retention approach in forests where logging occurs. This ecological approach to harvesting provides for permanent retention of important selected structures (e.g., trees and decayed logs) to provide for continuity of ecosystem structure, function, and species composition in the postharvest forest. The retention approach supports the integration of environmental, economic, and cultural values and is broadly applicable to tropical, temperate, and boreal forests, adaptable to different management objectives, and appropriate in different societal settings. The widespread adoption of the retention approach would be one of the most significant changes in management practice since the onset of modern high-yield forestry. C1 [Lindenmayer, D.

TI Motivational functionalism and urban conservation stewardship: implications for volunteer involvement SO CONSERVATION LETTERS LA English DT Letter DE Conservation psychology; conservation funding; urban biodiversity conservation; motivations; recruitment; retention; Seattle-Tacoma ID PARTICIPATION; MOTIVES; SERVICE AB Conservation in urban areas faces growing financial challenges and inadequate stakeholder involvement. Conservation psychology can mitigate these challenges in many ways. One way is through conservation volunteerism, if we attend to and capitalize on volunteers motivations. Conservation volunteerism significantly contributes to ecological knowledge acquisition, and public education and awareness of conservation issues. In this study, we explored volunteers motivations and how those motivations influence frequency of participation in urban conservation activities. We found that volunteers frequency of participation is most motivated by personal and social benefits rather than by environment-related reasons. Environmental motivations, otherwise marginally significant, were more salient predictors of participation to the extent that personal and social motivations were met. We discuss how ecologically focused strategies are likely to be less effective for motivating more frequent participation than motivationally based appeals to personal and social motivations of urban conservation. We discuss implications for urban conservation stewardship initiatives and suggest ways that decision makers can harness volunteers personal and social motivations to meet urban conservation practice and policy goals.

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

However, this conclusion needs to be proved carefully by field-scale experiments. In this study, a field-scale continuous openwarming experiment was conducted to quantify the adjustment of winter wheat growth and yield under conventional tillage (CT) and no-till (NT) systems in the North China Plain (NCP). Canopy temperatures were warmed using infrared heaters between 1.0 and 1.6 degrees C (daytime and nighttime, respectively) above the control. Wheat yields under CT were not significantly reduced over the two seasons (2010 and 2011), but yields under NT were 3.3% and 6.1% lower, respectively. The growing seasons for both CT and NT were shortened 6 days in 2010 and 11 days in 2011; however, the reproductive periods were maintained. The shortened days were due to a significantly shorter springtime re-greening stage followed by minimal changes in other phenological stages (jointing, flag completed, heading, anthesis, and grain-filling). The temporal advance by warming resulted in lower growing-season mean air temperatures (MAT) for warmed plots than the control from 0.23 to 4.22 degrees C for the same subsequent phenological stages. Warming increased the number of tillers m(-2) and kernel weight, but tended to decrease the number of spikes m(-2) in the two tillage systems. The heavier kernels offset the yield reduction from smaller number of spikes. Warming increased the wheat aboveground biomass from 10% to 20% suggesting the potential to sequester more CO2. This study suggests that winter wheat might adjust its growth (shortened vegetative period to maintain reproductive period) to partly compensate for the negative effects from global warming in this temperate irrigated cropland.

TI Effects of parents and Brown-headed Cowbirds (Molothrus ater) on nest predation risk for a songbird SO ECOLOGY AND EVOLUTION LA English DT Article DE Mono Lake; nest parasitism; nest predation; nest survival; parental behavior; population ecology; predator-prey interactions; Setophaga petechia; Yellow Warbler ID FIELDFARES TURDUS-PILARIS; ARTIFICIAL NEST; FOOD AVAILABILITY; BROOD PARASITISM; BEHAVIOR; HOST; SURVIVAL; SUCCESS; BIRDS; PATTERNS AB Nest predation limits avian fitness, so ornithologists study nest predation, but they often only document patterns of predation rates without substantively investigating underlying mechanisms. Parental behavior and predator ecology are two fundamental drivers of predation rates and patterns, but the role of parents is less certain, particularly for songbirds. Previous work reproduced microhabitat-predation patterns experienced by Yellow Warblers (Setophaga petechia) in the Mono Lake basin at experimental nests without parents, suggesting that these patterns were driven by predator ecology rather than predator interactions with parents. In this study, we further explored effects of post-initiation parental behavior (nest defense and attendance) on predation risk by comparing natural versus experimental patterns related to territory density, seasonal timing of nest initiation, and nest age. Rates of parasitism by Brown-headed Cowbirds (Molothrus ater) were high in this system (49% nests parasitized), so we also examined parasitism-predation relationships. Natural nest predation rates (NPR) correlated negatively with breeding territory density and nonlinearly (U-shaped relationship) with nest-initiation timing, but experimental nests recorded no such patterns. After adjusting natural-nest data to control for these differences from experimental nests other than the presence of parents (e. g., defining nest failure similarly and excluding nestling-period data), we obtained similar results. Thus, parents were necessary to produce observed patterns. Lower natural NPR compared with experimental NPR suggested that parents reduced predation rates via nest defense, so this parental behavior or its consequences were likely correlated with density or seasonal timing. In contrast, daily predation rates decreased with nest age for both nest types, indicating this pattern did not involve parents. Parasitized nests suffered higher rates of partial predation but lower rates of complete predation, suggesting direct predation by cowbirds. Explicit behavioral research on parents, predators (including cowbirds), and their interactions would further illuminate mechanisms underlying the density, seasonal, and nest age patterns we observed.

The aim was to explain the current geographic distribution of the species by investigating its genetic population structure. Samples of M. pygmaeus were collected in 15 localities through its range of distribution. A sample from a commercial producer was also analyzed. A total of 367 M. pygmaeus were genotyped for nine microsatellite loci. Isolation by distance was tested by Mantel's test. The molecular structure of M. pygmaeus populations was inferred by UPGMA, AMOVA, Principal component and Bayesian analyses. The average number of alleles per locus per population was 5.5 (range: 3.1-7.8). Istanbul (Turkey) and Nimes (France) had the lowest (0.291) and the highest (0.626) expected heterozygosity (H-e), respectively. There was an increase in H-e from the Canary Islands to Nimes, and a progressive decrease thereafter. A significant negative correlation was found between allelic richness and H-e, and the distance of each population to the easternmost locality (Canary Islands). Significant linkage disequilibrium was observed in the populations from Turkey. F-ST (0.004-0.334) indicated a high population differentiation, with isolation by distance supported by a high correlation. Bayesian analyses, PCA, and UPGMA pointed to three main clusters: (1) Greece and Turkey, (2) Italy and France, and (3) southern Iberia and the Canary Islands. The recent evolutionary history of M. pygmaeus is inferred from the data as follows: (1) the reduction in the geographic distribution of the species to the Iberian, Italian, and Balkan peninsulas, and possibly southern France, during glaciations and re-colonization of northern Europe from its southern refuges; (2) the maintenance of high diversity in Iberia and Italy (and possibly southern France) during contraction periods, and bottlenecks in the Balkans; (3) introgression of the Italian-French lineage in northern Spain, naturally or through trade.

TI A Comparative Study on Invasion, Survival, Modulation of Oxidative Burst, and Nitric Oxide Responses of Macrophages (HD11), and Systemic Infection in Chickens by Prevalent Poultry Salmonella Serovars SO FOODBORNE PATHOGENS AND DISEASE LA English DT Article ID IN-VIVO; MURINE SALMONELLOSIS; TYPHIMURIUM; ENTERITIDIS; IMMUNITY; KINASE; CELLS; PATHOGENESIS; REPLICATION; SUPPRESSION AB Poultry is a major reservoir for foodborne Salmonella serovars. Salmonella Typhimurium, Salmonella Enteritidis, Salmonella Heidelberg, Salmonella Kentucky, and Salmonella Senftenberg are the most prevalent serovars in U. S. poultry. Information concerning the interactions between different Salmonella species and host cells in poultry is lacking. In the present study, the above mentioned Salmonella serovars were examined for invasion, intracellular survival, and their ability to modulate oxidative burst and nitric oxide (NO) responses in chicken macrophage HD11 cells. All Salmonella serovars demonstrated similar capacity to invade HD11 cells. At 24 h post-infection, a 36-43% reduction of intracellular bacteria, in log(10)(CFU), was observed for Salmonella Typhimurium, Salmonella Heidelberg, Salmonella Kentucky, and Salmonella Senftenberg, whereas a significantly lower reduction (16%) was observed for Salmonella Enteritidis, indicating its higher resistance to the killing by HD11 cells. Production of NO was completely diminished in HD11 cells infected with Salmonella Typhimurium and Salmonella Enteritidis, but remained intact when infected with Salmonella Heidelberg, Salmonella Kentucky, and Salmonella Senftenberg. Phorbol myristate acetate-stimulated oxidative burst in HD11 cells was greatly impaired after infection by each of the five serovars. When newly hatched chickens were challenged orally, a high rate (86-98%) of systemic infection (Salmonella positive in liver/spleen) was observed in birds challenged with Salmonella Typhimurium, Salmonella Enteritidis, Salmonella Heidelberg, and Salmonella Kentucky, while only 14% of the birds were Salmonella Senftenberg positive. However, there was no direct correlation between systemic infection and in vitro differential intracellular survival and modulation of NO response among the tested serovars.

The behaviors of such groups are shaped by their diverse motivations and circumstances. Segmenting heterogeneous target groups into more homogeneous subgroups may improve the chances of successfully identifying policy strategies to influence their behavior. Findings from a multimethod study of nonindustrial private forest owners in eastern Oregon suggest four unique subgroups of owners with different fuel management motivations and suitabilities for policy tools: commodity managers could benefit from market-based incentives; amenity managers could benefit from capacity building programs paired with symbolic campaigns; recreational managers could benefit from public incentives provided through consultants or contractors who can help plan the work; and passive managers may benefit from opportunities to respond to the policy strategies designed for the other groupings until more information can be gathered. Incorporating qualitative analysis of interview data with statistical analysis of survey data improved understanding of the groupings and appropriate policy strategies for them.

TI An assessment of forest landowner interest in selling forest carbon credits in the Lake States, USA SO FOREST POLICY AND ECONOMICS LA English DT Article DE Forest carbon credits; Willingness to accept; Family forest owners; Carbon offset ID CONTINGENT VALUATION; OWNERS NEED; MECHANISMS; MANAGEMENT; STEWARDSHIP; CERTAINTY; VIRGINIA; FAILURE AB The nation's family forest lands can be an important contributor to carbon sequestration efforts. Yet very little is known about how family forest landowners view programs that enable them to sell carbon credits generated from the growth of their forest and the compensation that would be required to encourage a meaningful level of participation. To address this information gap, we conducted a study to identify and quantify family forest landowner interest in participating in a voluntary carbon market trading program in the Lake States, USA. A mail survey was administered to 2,200 randomly selected family forest owners in Michigan, Wisconsin, and Minnesota. The questionnaire assessed landowner interest in participating in a hypothetical carbon credit trading program and sought information on landowner objectives and practices, perspectives on carbon credit programs and forest land characteristics. A total of 850 usable responses were received. A logistic regression model was developed to examine the factors affecting participation in a forest carbon offset project by family forest owners and estimate landowner participation probability. Results show that carbon program characteristics alongside landowner and parcel characteristics are associated with the decision to participate in a carbon credit program. Specifically, carbon credit payment amount, contract length, gender, value placed on other non-market forest amenities, need for additional income, attitude towards climate change, absentee status, land tenure and total acres owned were found to be significant determinants. Our findings indicate that carbon sequestration management may align with the ownership goals of many family forest owners in the Lake States. (C) 2012 Elsevier B.V. All rights reserved.

Among coccidian parasites, the population structure of only Toxoplasma gondii has been extensively examined, Intraspecific variation in other coccidia, for example, those assigned to the genus Besnoitia, remains poorly defined. Here, we characterize the extent of genetic variation among populations of Besnoitia tarandi, a parasite whose intermediate host: include reindeer/caribou (Rangifer tarandus). Isolates from the Canadian Arctic and Finnish sub-Arctic were genotyped at six microsatellite loci, the first internal transcribed spacer region of nuclear rDNA, and the RNA polymerase beta subunit (rpoB) encoded in the plastid genome. Remarkably, all isolates exhibited the same multilocus genotype, regardless of the isolate's geographic origin. This absolute monomorphism occurred despite the capacity of these loci to vary, as established by evident differentiation between B. tarandi and two other species of Besnoitia, and variation among four isolates of B. besnoiti. The surprising lack of genetic variation across the sampled range suggests that B. tarandi may have experienced a recent population bottleneck. Published by Elsevier B.V.

Historically, two systems have been simultaneously used to classify NOV isolates into lineages or genotypes, generating confusion in the nomenclature and discrepancies in the assignment of genetic groups. In the present study we assessed the genetic diversity of the avian paramyxovirus type-1 (APMV-1) and propose a unified nomenclature and a classification system based on objective criteria to separate NDV into genotypes. Complete F gene sequences of class I (n = 110) and class II (n = 602) viruses were used for the phylogenetic reconstruction and to identify distinct taxonomic groups. The mean interpopulational evolutionary distance was estimated (10%) and set as the cutoff value to assign new genotypes. Results of our study revealed that class I viruses comprise a single genotype, while class II contains 15 genetic groups including 10 previously established (I-IX, and XI) and five new genotypes (X, XII, XIII, XIV and XV). Sub-genotypes were identified among class I and class II genotypes. Adoption of a unified nomenclature and of objective criteria to classify NDV isolates will facilitate studies on NOV epidemiology, evolution, disease control and diagnostics.

Their diversity and relationship to other kinds of coccidia have been successfully explored by molecular systematic studies based on the sequencing the 18S ribosomal DNA. To date, most attention has been paid to the diversity and evolutionary relationships of Eimeria spp. parasitizing terrestrial vertebrates, most especially those species infecting domesticated birds and mammals. Regrettably, no Eimeria have yet been considered from the Earth's first vertebrates: the fish. If Eimeria first evolved in fish, then extant piscine parasites should comprise a deeply branching assemblage at the base of well-constructed phylogenetic trees. Here, we sequenced portions of ribosomal DNA from several such isolates (from Eimeria anguillae, Eimeria daviesae, Eimeria percae, Eimeria variabilis, Eimeria rutili and Eimeria nemethi) and compared them to one another as well as to other available sequences from the parasites of fish and terrestrial vertebrates, in order to better understand their diversity and origins. By establishing that such piscine parasites comprise a deeply branching clade at the base of the Eimeriidae, these data substantiate the hypothesis that Eimeria may have originated in fish. Plainly, a great deal of coccidian diversity awaits future discovery and description. Published by Elsevier B.V.

TI Possible Evidence of Amide Bond Formation Between Sinapinic Acid and Lysine-Containing Bacterial Proteins by Matrix-Assisted Laser Desorption/Ionization (MALDI) at 355 nm SO JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY LA English DT Article DE Ammonium carboxylate salt; MALDI; Sinapinic acid; Amide bond; Lysine residue; N-terminus; Equilibrium retrogradation; 355 nm; Bacteria; CHCA; Protein; HdeA; HdeB; Dissociative loss ID FLIGHT MASS-SPECTROMETRY; TOP-DOWN PROTEOMICS; IN-SOURCE DECAY; RAPID IDENTIFICATION; INTACT MICROORGANISMS; ESCHERICHIA-COLI; MS; DESORPTION; BIOMARKERS; PEPTIDES AB We previously reported the apparent formation of matrix adducts of 3,5-dimethoxy-4-hydroxy-cinnamic acid (sinapinic acid or SA) via covalent attachment to disulfide bond-containing proteins (HdeA, Hde, and YbgS) from bacterial cell lysates ionized by matrix-assisted laser desorption/ionization (MALDI) time-of-flight-time-of-flight tandem mass spectrometry (TOF-TOF-MS/MS) and post-source decay (PSD). We also reported the absence of adduct formation when using alpha-cyano-4-hydroxycinnamic acid (CHCA) matrix. Further mass spectrometric analysis of disulfide-intact and disulfide-reduced over-expressed HdeA and HdeB proteins from lysates of gene-inserted E. coli plasmids suggests covalent attachment of SA occurs not at cysteine residues but at lysine residues. In this revised hypothesis, the attachment of SA is preceded by formation of a solid phase ammonium carboxylate salt between SA and accessible lysine residues of the protein during sample preparation under acidic conditions. Laser irradiation at 355 nm of the dried sample spot results in equilibrium retrogradation followed by nucleophilic attack by the amine group of lysine at the carbonyl group of SA and subsequent amide bond formation and loss of water. The absence of CHCA adducts suggests that the electron-withdrawing effect of the alpha-cyano group of this matrix may inhibit salt formation and/or amide bond formation. This revised hypothesis is supported by dissociative loss of SA (-224 Da) and the amide-bound SA (-206 Da) from SA-adducted HdeA and HdeB ions by MS/MS (PSD). It is proposed that cleavage of the amide-bound SA from the lysine side-chain occurs via rearrangement involving a pentacyclic transition state followed by hydrogen abstraction/migration and loss of 3-(4-hydroxy-3,5-dimethoxyphenyl)prop-2-ynal (-206 Da).

Fish fed diets 79 had significantly higher WG, FER, and PER than fish fed diet 1. Body protein decreased in fish fed diets 4 and 5, while body lipid tended to increase in fish fed WDDGS-containing diets. Fish fed diet 5 developed anemia. The number of days to first mortality was delayed and cumulative mortality 21-d post-challenge with Edwardsiella ictaluri was lower in fish fed WDDGS-containing diets relative to fish fed diet 1. Further decrease in mortality was obtained in fish fed diets with 2040% WDDGS, regardless of lysine supplementation. Serum protein, immunoglobulin, and lysozyme were unaffected by dietary treatments. Serum complement and antibody titer against E. ictaluri significantly differed among treatments but did not appear to be related to cumulative mortality following experimental challenge.

In order to gain a better understanding of the genes involved in attenuation and associate observed changes in phenotype with specific genetic variations, the genomic DNA sequence of a single GaHV-2 virulent strain (648A) was determined at defined passage intervals. Biological characterization of these "interval-isolates" in chickens previously indicated that the ability to induce transient paralysis was lost by passages 40 and the ability to induce persistent neurological disease was lost after passage 80, coincident with the loss of neoplastic lesion formation. Deep sequencing of the interval-isolates allowed for a detailed cataloguing of the mutations that exist within a single passage population and the frequency with which a given mutation occurs across passages. Gross genetic alterations were identified in both novel and well-characterized genes and cis-acting regions involved in replication and cleavage/packaging. Deletions in genes encoding the virulence factors vLipase, vIL8, and RLORF4, as well as a deletion in the promoter of ICP4, appeared between passages 61 and 101. Three mutations in the virus-encoded telomerase which predominated in late passages were also identified. Overall, the frequency of mutations fluctuated greatly during serial passage and few genetic changes were absolute. This indicates that serial passage of GaHV-2 results in the generation of a collection of genomes with limited sequence heterogeneity.

Some Oxytropis spp. locoweeds contain a seed-transmitted endophytic fungus, Undifilum oxytropis, which produces the toxic alkaloid swainsonine. We sought to localize and characterize growth patterns of the fungus within leaves and petioles of Oxytropis lambertii Pursh and Oxytropis sericea Nutt. to help define the types of interactions between the fungus and its hosts. Vegetative hyphae were observed within locoweed tissues using integrated imaging. Topographical images from scanning electron microscopy revealed the presence of the endophyte in the pith tissue of petioles. The fungus was identified between plant cells but did not appear to penetrate host cells. Transmission electron microscopy images of thin sections revealed that hyphae were closely associated with host cell walls. Oxytropis sericea was innoculated with green fluorescent protein-transformed U. oxytropis and observed by confocal microscopy, confirming the presence of the endophyte hyphae in leaves and petioles. The fungus was identified only in the pith of petioles using fluorescence and in the vascular bundle throughout extracellular spaces in leaves. These results revealed no signs of a pathogenic interaction between plant and fungus and support the hypothesis of a mutualistic or commensal relationship.

Yet, forest C density varies greatly in space, both globally and at stand and landscape levels. Understanding the multi-scale drivers of this variation is a prerequisite for robust and effective climate change mitigation in ecosystem management. Here, we used airborne light detection and ranging (Lidar) and a novel high-resolution simulation model of landscape dynamics (iLand) to identify the drivers of variation in C density for an old-growth forest landscape in Oregon, USA. With total ecosystem C in excess of 1 Gt ha(-1) these ecosystems are among the most C-rich globally. Our findings revealed considerable spatial variability in stand-level C density across the landscape. Notwithstanding the distinct environmental gradients in our mountainous study area only 55.3% of this variation was explained by environmental drivers, with radiation and soil physical properties having a stronger influence than temperature and precipitation. The remaining variation in C stocks was largely attributable to emerging properties of stand dynamics (that is, stand structure and composition). Not only were density- and size-related indicators positively associated with C stocks but also diversity in composition and structure, documenting a close link between biodiversity and ecosystem functioning. We conclude that the complexity of old-growth forests contributes to their sustained high C levels, a finding that is relevant to managing forests for climate change mitigation.

Bleaching has been applied to whiten nut shells for antifungal and cosmetic purposes. However, the impact of bleaching on nutritional quality and safety of pistachios remains to be examined. In this study, we investigated whether bleaching would increase malondialdehyde (MDA) or 7-keto-sitosterol and decrease phytosterols in pistachio oil, as well as cause cytotoxicity of modeled Hepa1c1c7 cells. Bleaching increased MDA by more than 32% from 0.23 mu g/g in raw oil, with the largest increase noted with the bleach containing H2O2 and Fe2+ (P?=?0.05). Bleached pistachio oil had larger than 12.6% decrease in beta-sitosterol and total phytosterols as compared to the raw oil (P?=?0.05). Bleaching with Fe2+ significantly increase 7-keto-sitosterol compared to bleaching alone. Hepatic cell viability was decreased the most by the oil of the pistachios treated with bleach containing Fe2+ (P?=?0.05), and lactate dehydrogenase activity in medium was elevated by >18-folds (P?=?0.05). Compared to natural pistachios, the bleaching treatment had detrimental effects on nutritional quality and expected health benefits of pistachios by increasing lipid peroxidation, decreasing phytosterol content, and causing cytotoxicity.

Through five case histories across the region, we explore how a changing climate has been affecting streams and the potential consequences for trout. Monitoring records show trends in temperature and hydrographs consistent with a warming climate in recent decades. Biological implications include upstream shifts in thermal habitats, risk of egg scour, increased wildfire disturbances, and declining summer habitat volumes. The importance of these factors depends on the context, but temperature increases are most relevant where population boundaries are mediated by thermal constraints. Summer flow declines and wildfires will be important where trout populations are fragmented and constrained to small refugia. A critical information gap is evidence documenting how populations are adjusting to long-term habitat trends, so biological monitoring is a priority. Biological, temperature, and discharge data from monitoring networks could be used to develop accurate vulnerability assessments that provide information regarding where conservation actions would best improve population resilience. Even with better information, future uncertainties will remain large due to unknowns regarding Earth's ultimate warming trajectory and how effects translate across scales. Maintaining or increasing the size of habitats could provide a buffer against these uncertainties. C1 [Isaak, Daniel J.] US Forest Serv, Rocky Mt Res Stn, Boise, ID 83702 USA.

To do this, survivorship relative to survivorship on isoline maize (i.e. the same genetic background, but without Cry3Bb1) was evaluated. Comparisons were made using low (16502500 eggs/m) and high (33003500 eggs/m) western corn rootworm egg densities. Significantly fewer beetles were recovered from MON863 than from isoline maize. Emergence from MON863 as a percentage of viable eggs ranged from 0.02% to 0.10%, whereas percentage emergence from isoline maize ranged from 1.09% to 7.14%. Survivorship on MON863 relative to survivorship on isoline averaged 1.51% when averaged across all environments and both years, so mortality because of the Cry3Bb1 protein averaged 98.49%. The average time delay to 50% cumulative beetle emergence from MON863 was 18.3 days later than from isoline maize. Females comprised 56% and 71% of total beetles recovered from MON863 in 2003 and 2004, respectively. Results are discussed in relation to insect resistance management (IRM) of western corn rootworm.

Cry3Bb delta endotoxins expressed by Bt maize specifically target corn rootworms (genus Diabrotica) and have proven highly efficacious. However, development of resistance to Bt maize, especially among western corn rootworm (Diabrotica virgifera virgifera) populations, poses a significant threat to the future viability of this pest control biotechnology. The structured refuge insect resistance management (IRM) strategy implemented in the United States for Bt maize adopts a conservative approach to managing resistance by assuming no fitness costs of Bt resistance, even though these trade-offs strongly influence the dynamics of Bt resistance within numerous agricultural pest species. To investigate the effects of Bt resistance on fitness components of western corn rootworm, we compared survivorship, fecundity and viability of five Bt-resistant laboratory lines reared on MON863 (YieldGard Rootworm), a Bt maize product that expresses Cry3Bb1 delta endotoxin, and on its non-transgenic isoline. Analysis of performance on the isoline maize demonstrated no fitness costs associated with Bt resistance. In fact, resistant lines emerged approximately 23 days earlier than control lines when reared on both MON863 and the isoline, indicating that selection for Bt resistance resulted in a general increase in the rate of larval development. In addition, resistant lines reared on Bt maize displayed higher fecundity than those reared on the isoline, which may have significant management implications. These data will be valuable for formulating improved IRM strategies for a principal agricultural pest of maize. C1 [Oswald, K.

TI Gene silencing in adult Aedes aegypti mosquitoes through oral delivery of double-stranded RNA SO JOURNAL OF APPLIED ENTOMOLOGY LA English DT Article DE mosquito; RNAi; v-ATPase; vector control ID ANOPHELES-GAMBIAE; INSECTICIDE RESISTANCE; DSRNA INGESTION; VECTOR CONTROL; INTERFERENCE; MALARIA; LARVAL; POPULATIONS; KNOCKDOWN; ALIGNMENT AB The induction of the naturally occurring phenomenon of RNA interference (RNAi) to study gene function in insects is now common practice. With appropriately chosen targets, the RNAi pathway has also been exploited for insect control, typically through oral delivery of dsRNA. Adapting current methods to deliver foreign compounds, such as amino acids and pesticides, to mosquitoes through sucrose solutions, we tested whether such an approach could be used in the yellow fever mosquito, Aedes aegypti. Using a non-specific dsRNA construct, we found that adult Ae. aegypti ingested dsRNA through this method and that the ingested dsRNA can be recovered from the mosquitoes post-feeding. Through the feeding of a species-specific dsRNA construct against vacuolar ATPase, subunit A, we found that significant gene knockdown could be achieved at 12, 24 and 48 h post-feeding. C1 [Coy, M.

The diagnosis of type 1A glycogen storage disease was made via the result of a liver biopsy, which showed increased glycogen and absent glucose-6-phosphatase enzyme activity. The patient was treated with dextrose administered orally, which was replaced by frequent feedings of cornstarch, which resulted in an improvement of her metabolic parameters. At age 18 years of age, she had marked hypertriglyceridemia (3860 mg/dL) and eruptive xanthomas and was treated with fenofibrate, atorvastatin, and fish oil. At age 29 years she was noted to have multiple liver adenomas, severe anemia, and hyperuricemia. Aggressive cornstarch therapy was commenced with a goal of maintaining her blood glucose levels >75 mg/dL and lactate levels <2 mmol/L. After 15 months on this regimen, her lipids levels (measured in mg/dL) off all medications were as follows: total cholesterol 222, triglycerides 179, high-density lipoprotein cholesterol 32, and calculated low-density lipoprotein cholesterol 154. Her weight was stable with a body mass index of 24.8 kg/m(2). Her liver adenomas had decreased in size, and her anemia and hyperuricemia had improved. She was homozygous for the R83C missense mutation in G6PC. Our data indicate that optimized metabolic control to maintain blood glucose levels >75 mg/dL is critical in the management of this disease.

However, chlorine reacts rapidly with organic materials, leading to potential pathogen survival when chlorine concentration nears depletion. This study evaluated a new process aid, T128, for its capacity to enhance chlorine efficacy against Escherichia coli O157:H7 in solutions with high organic loads. Chlorine solutions were prepared with either T128 or citric acid (control) to adjust pH. Survival of E.?coli O157:H7 was assayed during washing of increasing amounts of shredded lettuce, or addition of lettuce juice as organic load. The application of T128 significantly reduced survival of E.?coli O157:H7 when free chlorine in solution decreased to levels approaching depletion. In the presence of T128, no pathogen survival was observed with the free chlorine concentration as low as 0.05?mg/L, while 0.4?mg/L free chlorine was required to kill pathogens in the absence of T128 in the wash solution. Practical Applications The foodborne illness outbreaks that plague the fresh-cut produce industry are a testament to the need for a more effective sanitizer to prevent pathogen survival and cross contamination in commercial produce wash systems with large influxes of organic matter. This paper reports the investigation of the effect of a new process aid, T128, on reducing the survival of E.?coli O157:H7 in wash solutions in which chlorine is near depletion due to high organic load, and thus the potential to improve the safety margin of fresh-cut process control.

TI Detection of Escherichia coli O157:H7 and Salmonella enterica in Air and Droplets at Three U.S. Commercial Beef Processing Plants SO JOURNAL OF FOOD PROTECTION LA English DT Article ID CARCASS CONTAMINATION; UNITED-STATES; IMMUNOMAGNETIC SEPARATION; GROUND-BEEF; O157-H7; CATTLE; PREVALENCE; HIDES; ABATTOIRS; BACTERIA AB Bacteria are known to be present in the air at beef processing plants, but published data regarding the prevalences of airborne Escherichia coli O157:H7 and Salmonella enterica are very limited. To determine if airborne pathogens were present in beef processing facilities, we placed sedimentation sponges at various locations in three commercial beef plants that processed cattle from slaughter through fabrication. For the 291 slaughter area air samples, E. coli O157:H7 was isolated from 15.8% and S. enterica from 16.5%. Of the 113 evisceration area air samples, E. coli O157:H7 was isolated from only one sample and S. enterica was not isolated from any sample. Pathogens were not isolated from any of the 87 air samples from fabrication areas. Pathogen prevalences, aerobic plate counts, and Enterobacteriaceae counts were highest for air samples obtained from locations near hide removal operations. The process of hide removal disperses liquid droplets, which may contact neighboring carcasses. Samples were obtained both from hide removal locations that were close enough to hide pullers to be contacted by droplets and from locations that were not contacted by droplets. Higher pathogen prevalences, aerobic plate counts, and Enterobacteriaceae counts were observed at locations with samples contacted by the hide removal droplets. We conclude that the hide removal processes likely introduce pathogens into the air via a dispersion of liquid droplets and that these droplets may be an underappreciated source of hide-to-carcass contamination.

TI Antimicrobial Activity of Allyl Isothiocyanate Used To Coat Biodegradable Composite Films as Affected by Storage and Handling Conditions SO JOURNAL OF FOOD PROTECTION LA English DT Article ID LISTERIA-MONOCYTOGENES; NISIN; PECTIN AB We evaluated the effects of storage and handling conditions on the antimicrobial activity of biodegradable composite films (polylactic acid and sugar beet pulp) coated with allyl isothiocyanate (AIT). Polylactic acid and chitosan were incorporated with AIT and used to coat one side of the film. The films were subjected to different storage conditions (storage time, storage temperature, and packed or unpacked) and handling conditions (washing. abrasion, and air blowing), and the antimicrobial activity of the films against Salmonella Stanley in tryptic soy broth was determined. The films (8.16 mu l of ALT per cm(2) of surface area) significantly (P<0.05) inhibited the growth of Salmonella during 24 h of incubation at 22 degrees C, while the populations of Salmonella in controls increased from ca. 4 to over 8 log CFU/ml, indicating a minimum inactivation of 4 log CFU/ml on films in comparison to the growth on controls. Statistical analyses indicated that storage time, storage temperature, and surface abrasion affected the antimicrobial activity of the films significantly (P<0.05). However, the differences in microbial reduction between those conditions were less than 0.5 log cycle. The results suggest that the films' antimicrobial properties are stable under practical storage and handling conditions and that these antimicrobial films have potential applications in food packaging.

TI Effect of Stress on Non-O157 Shiga Toxin-Producing Escherichia coli SO JOURNAL OF FOOD PROTECTION LA English DT Review ID ACID RESISTANCE; UNITED-STATES; SALMONELLA-TYPHIMURIUM; FOODBORNE ILLNESS; SURVIVAL; O157-H7; O157/H7; STRAINS; BEEF; O26 AB Non-O157 Shiga toxin producing Escherichia coli (non-O157 STEC) strains have emerged as important foodborne pathogens worldwide. Non-O157 STEC serogroups O26, O45, O103, O111, O121, and O145 have been declared as adulterants in beef by the U.S. Department of Agriculture Food Safety and Inspection Service. While documentation is limited, treatments including heat and acid that have been shown to inactivate E. cell O157:117 will likely also destroy non-O157 STEC: however, non-O157 STEC strains show variability in their responses to stress. It has been shown that non-O157 STEC may survive in fermented sausages and cheeses, and treatments such as high pressure may be necessary to eliminate non-O157 STEC from these products. The mechanisms used by non-O157 STEC to resist acid environments are similar to those used by O157:H7 strains and include the acid tolerance response, the oxidative system, and the glutamate and arginine decarboxylase systems. However, one study demonstrated that some non-O157 STEC strains utilize a chaperone-based acid stress response (HdeA and HdeB) to combat acidic conditions, which is lacking in E. coli O157:H7. Genomic studies suggest that while non-O157 STEC can cause diseases similar to those caused by E. call O157:H7, O157 and non-O157 STECs have different evolutionary histories. Non-O157 STECs are a heterogeneous group of organisms, and there is currently a limited amount of information on their virulence, fitness, and stress responses, rendering it difficult to draw firm conclusions on their behavior when exposed to stress in the environment, in food, and during processing.

We conducted surveys along 16 rivers in Missouri and Arkansas from 1999 to 2006 and related habitat and landscape factors to counts of Cerulean Warblers in 123 5-km segments on these rivers. We detected 576 singing male Cerulean Warblers and found support for both local and landscape effects on Cerulean Warbler abundance. Model fit was good with an average correlation of 0.841 between predicted and observed values based on an eight-fold cross-validation procedure. The abundance of Cerulean Warblers increased 390.7. 8.7, and 4.1 times across the observed range of forest within 10 km, bottomland forest within 250 m, and upland forest within 250 m, respectively. Conservation and research need to address large-scale forest patterns in addition to local habitat for Cerulean Warblers. Further research is needed on abundance patterns across riparian and upland forests and demographic rates in this part of their range. Received 17 April 2012. Accepted 19 June 2012.

For the carrion system, we hypothesized that volatiles to which primary colonizers, such as blow flies, respond are the same signalling molecules produced and utilized for quorum sensing by bacteria found on the resource. We provided freshly emerged blow flies, Lucilia sericata, different diets (blood or powdered milk) and assessed their behaviour in a dual-choice assay based on sex and ovarian status of 7-day-old or 14-day-old adults. We determined their preference between wild-type Proteus mirabilis, which is able to swarm (a quorum-sensing response), or mutated (by transposon mutagenesis) P. mirabilis, which is unable to swarm. In most instances, an individual's sex did not significantly influence its response. Age and diet appeared to regulate fly motivation and preference. Seven-day-old flies had a significantly greater probability of responding to the wild type than to the mutant, regardless of diet, but the percentage of milk-fed flies that responded was significantly smaller (85% less) than the percentage of blood-fed flies that responded. Blood-fed flies oviposited, whereas milk-fed flies did not. Seven-day-old flies oviposited predominately on the wild type, whereas 14-day-old flies oviposited predominately on the mutant. Our results demonstrate that the mechanism used by L. sericata for detecting a resource can be associated with bacterial quorum sensing, and that the physiological state of the insect influences its response. We also identified several differences in volatile compounds produced by the bacteria that could explain blow fly response. (C) 2012 The Association for the Study of Animal Behaviour.

Using manipulative field experiments, we assessed how N2O and CH4 soil fluxes responded to a rise in atmospheric carbon dioxide (CO2) concentration and to increased air temperature. Nitrous oxide and CH4 responses varied greatly among studied ecosystems. Elevated CO2 often stimulated N2O emissions in fertilized systems and CH4 emissions in wetlands, peatlands, and rice paddy fields; both effects were stronger in clayey soils than in sandy upland soils. Elevated temperature, however, impacted N2O and CH4 emissions inconsistently. Thus, the effects of elevated CO2 concentrations on N2O and CH4 emissions may further enhance global warming, but it remains unclear whether increased temperature generates positive or negative feedbacks on these GHGs in terrestrial ecosystems.

Here, we assess contemporary biogenic CH4 and N2O budgets and probable climate-change-related impacts on CH4 and N2O emissions in terrestrial North America. Multi-approach estimations show that, during 1990-2010, biogenic CH4 emissions ranged from 0.159 to 0.502 petagrams of carbon dioxide (CO2) equivalents per year (Pg CO(2)eq yr(-1), where 1 Pg = 1 x 10(15) g) and N2O emissions ranged from 0.802 to 1.016 Pg CO(2)eq yr(-1), which offset 47-166% of terrestrial CO2 sequestration (0.915-2.040 Pg CO(2)eq yr(-1), as indicated elsewhere in this Special Issue). According to two future climate scenarios, CH4 and N2O emissions are projected to continue increasing by 137-151% and 157-227%, respectively, by the end of this century, as compared with levels during 2000-2010. Strategies to mitigate climate change must account for non-CO2 GHG emissions, given their substantial warming potentials.

However, N losses from agricultural systems have resulted in numerous deleterious environmental impacts, including a continuing increase in atmospheric nitrous oxide (N2O), a greenhouse gas (GHG) and an important catalyst of stratospheric ozone depletion. Although associated with about 7% of total US GHG emissions, agricultural systems account for 75% of total US N2O emissions. Increased productivity in the crop and livestock sectors during the past 30 to 70 years has resulted in decreased N2O emissions per unit of production, but N2O emissions from US agriculture continue to increase at a rate of approximately 0.46 teragrams of carbon dioxide equivalents per year (2002-2009). This rate is lower than that during the late 20th century. Improvements in agricultural productivity alone may be insufficient to lead to reduced emissions; implementing strategies specifically targeted at reducing N2O emissions may therefore be necessary.

TI Management opportunities for enhancing terrestrial carbon dioxide sinks SO FRONTIERS IN ECOLOGY AND THE ENVIRONMENT LA English DT Review ID LAND-USE CHANGE; DISSOLVED ORGANIC-CARBON; PINE PLANTATIONS; META ANALYSIS; SOIL C; SEQUESTRATION; AGRICULTURE; EMISSIONS; BIOENERGY; BIOFUELS AB The potential for mitigating increasing atmospheric carbon dioxide concentrations through the use of terrestrial biological carbon (C) sequestration is substantial. Here, we estimate the amount of C being sequestered by natural processes at global, North American, and national US scales. We present and quantify, where possible, the potential for deliberate human actions - through forestry, agriculture, and use of biomass-based fuels - to augment these natural sinks. Carbon sequestration may potentially be achieved through some of these activities but at the expense of substantial changes in land-use management. Some practices (eg reduced tillage, improved silviculture, woody bioenergy crops) are already being implemented because of their economic benefits and associated ecosystem services. Given their cumulative greenhouse-gas impacts, other strategies (eg the use of biochar and cellulosic bioenergy crops) require further evaluation to determine whether widespread implementation is warranted.

Here, we highlight the factors that make mitigating N2O emissions from fertilized agroecosystems such a difficult challenge, and discuss how these factors limit the effectiveness of existing practices and therefore require new technologies and fresh ideas. Modification of the rate, source, placement, and/or timing of nitrogen fertilizer application has in some cases been an effective way to reduce N2O emissions. However, the efficacy of existing approaches to reducing N2O emissions while maintaining crop yields across locations and growing seasons is uncertain because of the interaction of multiple factors that regulate several different N2O-producing processes in soil. Although these processes have been well studied, our understanding of key aspects and our ability to manage them to mitigate N2O emissions remain limited.

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

These correlations indicate that measurements of one trait carry information on other traits. Current single-trait (univariate) genomic selection does not take advantage of this information. Multivariate genomic selection on multiple traits could accomplish this but has been little explored and tested in practical breeding programs. In this study, three multivariate linear models (i.e., GBLUP, BayesA, and BayesC pi) were presented and compared to univariate models using simulated and real quantitative traits controlled by different genetic architectures. We also extended BayesA with fixed hyperparameters to a full hierarchical model that estimated hyperparameters and BayesCp to impute missing phenotypes. We found that optimal marker-effect variance priors depended on the genetic architecture of the trait so that estimating them was beneficial. We showed that the prediction accuracy for a low-heritability trait could be significantly increased by multivariate genomic selection when a correlated high-heritability trait was available. Further, multiple-trait genomic selection had higher prediction accuracy than single-trait genomic selection when phenotypes are not available on all individuals and traits. Additional factors affecting the performance of multiple-trait genomic selection were explored. C1 [Jia, Yi; Jannink, Jean-Luc] Cornell Univ, Dept Plant Breeding & Genet, Ithaca, NY 14853 USA.

TI Productivity and botanical composition of orchardgrass-white clover swards in a cool-temperate hill land region of the eastern United States SO GRASSLAND SCIENCE LA English DT Article DE Canopy height; herbage mass; regrowth interval; residue height; sward composition ID MIXTURES; GROWTH; PERFORMANCE; CULTIVARS; PASTURE; COMPETITION; VARIETIES; GRASSES; FORAGES; SEASON AB Understanding the growth dynamics of grasslegume swards is critical as pastoral management practices are adapted to varying economic constraints and emerging environmental considerations. Efficient management must synchronize the use of accumulated herbage with the needs of grazing livestock. This must be accomplished against the dynamic background of within and among year weather patterns interacting with herbage growth and grazing animal behavior. In the Appalachian region of the eastern United States, pastures often are dominated by orchardgrass (Dactylis glomerata L.) and white clover (Trifolium repens L.). We determined botanical composition and herbage productivity of orchardgrass and white clover swards during four consecutive years when managed as a function of canopy development and regrowth interval. Productivity was influenced by defoliation practices when mixtures were managed according to canopy development. Productivity was greatest when swards were managed as hay or when clipped to a 5-cm residue each time mean canopy height reached 20 cm. White clover declined and orchardgrass increased in the sward irrespective of defoliation treatment. Botanical composition of mixtures with the erect growing orchardgrass tended to be more stable, whereas swards including the decumbent orchardgrass tended to be invaded by weeds. Some increase in productivity occurred during the first growing season when mixtures were clipped at either 2- or 4-week intervals. Regardless of defoliation practice, white clover, and in some instances orchardgrass, presence declined during two consecutive growing seasons with various other volunteer grasses and forbs contributing to productivity. Productivity and persistence of sown sward components may be less dependent on management practices than on the expression of interactions responding to within and among year weather patterns.

Increased ceramide content and NF kappa B signaling may contribute to the attenuation of anabolic signaling after resistance exercise in aged males. J Appl Physiol 113: 1727-1736, 2012. First published October 4, 2012; doi:10.1152/japplphysiol.00412.2012.-One of the most fundamental adaptive physiological events is the response of skeletal muscle to high-intensity resistance exercise, resulting in increased protein synthesis and ultimately larger muscle mass. However, muscle growth in response to contraction is attenuated in older humans. Impaired contractile-induced muscle growth may contribute to sarcopenia: the age-associated loss of muscle mass and function that is manifested by loss of strength, contractile capacity, and endurance. We hypothesized that the storage of ceramide would be increased in older individuals and this would be associated with increases in NF kappa B signaling and a decreased anabolic response to exercise. To test this hypothesis we measured ceramides at rest and anabolic and NF kappa B signaling after an acute bout of high-intensity resistance exercise in young and older males. Using lipidomics analysis we show there was a 156% increase in the accumulation of C16:0-ceramide (P < 0.05) and a 30% increase in C20:0-ceramide (P < 0.05) in skeletal muscle with aging, although there was no observable difference in total ceramide. C16: 0-ceramide content was negatively correlated (P = 0.008) with lower leg lean mass. Aging was associated with a similar to 60% increase in the phosphorylation of the proinflammatory transcription factor NF kappa B in the total and nuclear cell fractions (P < 0.05). Furthermore, there was an attenuated activation of anabolic signaling molecules such as Akt (P < 0.05), FOXO1 (P < 0.05), and S6K1 (P < 0.05) after an acute bout of high-intensity resistance exercise in older males. We conclude that ceramide may have a significant role in the attenuation of contractile-induced skeletal muscle adaptations and atrophy that is observed with aging.

TI Brucellosis Seroprevalence Among Workers in At-Risk Professions Northwestern Wyoming, 2005 to 2006 SO JOURNAL OF OCCUPATIONAL AND ENVIRONMENTAL MEDICINE LA English DT Article ID PREVALENCE; ANTIBODIES; ELK AB Objective: Brucellosis is uncommon in the United States; however, its circulation among wildlife and domestic cattle has been ongoing in Wyoming. To assess the public health threat of brucellosis circulation among animals, a seroprevalence study was undertaken among workers in professions considered to be at the highest risk for infection. Methods: A seroprevalence study was undertaken targeting individuals in at-risk professions in the affected area of the state. Results: Seroprevalence among study participants was 14.4%. Veterinarians were the main professional group that demonstrated a statistically significant association with measurable anti-Brucella antibodies. Vaccinating animals with Brucella vaccines was associated with seropositivity. Conclusion: The risk to the general public's health from the circulation of Brucella among wildlife and cattle can be attributed primarily to a limited subpopulation at high risk rather than a generally elevated risk.

Tillering is an essential factor used to determine the overall architecture of cereal crops. It has long been recognized that the development of branching patterns is controlled by the level and distribution of auxin within a plant. To better understand the relationship between auxin levels and tittering in rice, we examined rice plants with increased or decreased levels of free IAA. To decrease IAA levels, we selected the rice IAA-glucose synthase gene (OsIAGLU) from the rice genome database based on high sequence homology with IAA-glucose synthase from maize (ZmIAGLU), which is known to generate IAA-glucose conjugate from free IAA. The OsIAGLU gene driven by the Cauliflower Mosaic Virus 35S promoter was transformed into a rice cultivar to generate transgenic rice plants constitutively over-expressing this gene. The number of tillers and panicles significantly increased in the transgenic lines compared to the wild-type plants, while plant height and panicle length decreased. These results indicate that decreased levels of free IAA likely enhance tiller formation in rice. To increase levels of free IAA, we treated rice plants with three different concentrations of exogenous IAA (1 mu M, 10 mu M and 100 mu M) twice a week by spraying. Exogenous IAA treatment at concentrations of 10 mu M and 100 mu M significantly reduced tiller number in three different rice cultivars. These results indicate that exogenously applied IAA inhibits shoot branching in rice. Overall, auxin tightly controls tiller formation in rice in a negative way.

(Diptera: Muscidae), is one of the most significant biting flies that affect cattle. The use of traditional insecticides for stable fly control has only a limited success owing to the insect's unique feeding behaviours and immature development sites. A laboratory study was conducted to evaluate the effects of two insect growth regulator (IGR) products, pyriproxyfen and buprofezin, on the development of the immature stages of the stable fly and the effects of pyriproxyfen on oviposition and egg hatch. Both pyriproxyfen and buprofezin had significant inhibitory effects on immature development. The LC50s of pyriproxyfen and buprofezin were 0.002 and 18.92 p.p.m., respectively. Topical treatment of adult females with different doses of pyriproxyfen had significant negative effects on both female oviposition and egg hatching when 1- and 3-day-old females were treated, and the effects were dose dependent. A significant reduction in the mean number of eggs laid was observed only at the highest pyriproxyfen dose (8 mu g/fly) and egg hatch was unaffected by pyriproxyfen treatment when 5-day-old females were treated. Results from the present study indicate that pyriproxyfen has the potential to be used as part of an integrated stable fly management programme. C1 [Liu, S. S.; Li, A. Y.; Lohmeyer, K.

AB Scope The aims of this study were to evaluate IgE-mediated hypersensitivity to pine nut with details of clinical reactions and to characterize major pine nut allergens. Methods and results The study included ten consecutive teenagers and adults diagnosed with IgE-mediated clinical allergy to pine nut. Two major pine nut allergens were purified and identified and the secondary structures and susceptibility to digestion were characterized. Severe reactions represent 80% of allergic reactions to pine nut in this study. Moreover, 70% of the patients were monosensitized to this nut. Two major allergens with molecular weights of 6 and 50 kDa were purified and identified as albumin and vicilin, respectively. The 6 kDa protein (albumin), rich in a-helix content, was far more stable to peptic and tryptic digestion as compared with 50 kDa protein (vicilin), which was quickly broken down. The secondary structure of the purified 50 kDa protein showed 41% beta-sheet, 5% alpha-helix, and 54% random coil and/or loops. Conclusion Eighty percent of allergic reactions to pine nut in the ten patients included in this study were severe. Most patients (70%) were monosensitized to this nut. Two major allergens with molecular weights of 6 and 50 kDa were purified and identified as albumin and vicilin, respectively.

Co-expression of CRT and sCAX1 could alleviate the hypersensitivity to ion imbalance in tobacco plants. Furthermore, blossom-end rot (BER) in tomato may be linked to changes in CAX activity and enhanced CRT expression mitigated BER in sCAX1 expressing lines. These findings suggest that co-expressing Ca2+ transporters and binding proteins at different intracellular compartments can alter the content and distribution of Ca2+ within the plant matrix.

TI Ozone Exposure Response for U.S. Soybean Cultivars: Linear Reductions in Photosynthetic Potential, Biomass, and Yield SO PLANT PHYSIOLOGY LA English DT Article ID LEAF OPTICAL-PROPERTIES; ELEVATED OZONE; ANTIOXIDANT CAPACITY; CELL-DEATH; CHLOROPHYLL FLUORESCENCE; TROPOSPHERIC OZONE; DEPENDENT CHANGES; OXIDATIVE STRESS; CARBON-DIOXIDE; CLIMATE-CHANGE AB Current background ozone (O-3) concentrations over the northern hemisphere's midlatitudes are high enough to damage crops and are projected to increase. Soybean (Glycine max) is particularly sensitive to O-3; therefore, establishing an O-3 exposure threshold for damage is critical to understanding the current and future impact of this pollutant. This study aims to determine the exposure response of soybean to elevated tropospheric O-3 by measuring the agronomic, biochemical, and physiological responses of seven soybean genotypes to nine O-3 concentrations (38-120 nL L-1) within a fully open-air agricultural field location across 2 years. All genotypes responded similarly, with season-long exposure to O-3 causing a linear increase in antioxidant capacity while reducing leaf area, light absorption, specific leaf mass, primary metabolites, seed yield, and harvest index. Across two seasons with different temperature and rainfall patterns, there was a robust linear yield decrease of 37 to 39 kg ha(-1) per nL L-1 cumulative O-3 exposure over 40 nL L-1. The existence of immediate effects of O-3 on photosynthesis, stomatal conductance, and photosynthetic transcript abundance before and after the initiation and termination of O-3 fumigation were concurrently assessed, and there was no evidence to support an instantaneous photosynthetic response. The ability of the soybean canopy to intercept radiation, the efficiency of photosynthesis, and the harvest index were all negatively impacted by O-3, suggesting that there are multiple targets for improving soybean responses to this damaging air pollutant.

TI Differential Control of Ethylene Responses by GREEN-RIPE and GREEN-RIPE LIKE1 Provides Evidence for Distinct Ethylene Signaling Modules in Tomato SO PLANT PHYSIOLOGY LA English DT Article ID RECEPTOR GENE FAMILY; RAF-LIKE KINASE; ARABIDOPSIS-THALIANA; ENDOPLASMIC-RETICULUM; NEGATIVE REGULATOR; MULTIGENE FAMILY; GOLGI-APPARATUS; ETR1; EIN2; EXPRESSION AB The factors that mediate specific responses to the plant hormone ethylene are not fully defined. In particular, it is not known how signaling at the receptor complex can control distinct subsets of ethylene responses. Mutations at the Green-ripe (Gr) and reversion to ethylene sensitivity1 (rte1) loci, which encode homologous proteins of unknown function, influence ethylene responses in tomato (Solanum lycopersicum) and Arabidopsis (Arabidopsis thaliana), respectively. In Arabidopsis, AtRTE1 is required for function of the ETR1 ethylene receptor and acts predominantly through this receptor via direct protein-protein interaction. While most eudicot families including the Brassicaceae possess a single gene that is closely related to AtRTE1, we report that members of the Solanaceae family contain two phylogenetically distinct genes defined by GR and GREEN-RIPE LIKE1 (GRL1), creating the possibility of subfunctionalization. We also show that SlGR and SlGRL1 are differentially expressed in tomato tissues and encode proteins predominantly localized to the Golgi. A combination of overexpression in tomato and complementation of the rte1-3 mutant allele indicates that SlGR and SlGRL1 influence distinct but overlapping ethylene responses. Overexpression of SlGRL1 in the Gr mutant background provides evidence for the existence of different ethylene signaling modules in tomato that are influenced by GR, GRL1, or both. In addition, overexpression of AtRTE1 in tomato leads to reduced ethylene responsiveness in a subset of tissues but does not mimic the Gr mutant phenotype. Together, these data reveal species-specific heterogeneity in the control of ethylene responses mediated by members of the GR/RTE1 family.

TI 14-3-3 Proteins SGF14c and SGF141 Play Critical Roles during Soybean Nodulation SO PLANT PHYSIOLOGY LA English DT Article ID GENE-EXPRESSION; GLUTAMINE-SYNTHETASE; MEDICAGO-TRUNCATULA; NITRATE REDUCTASE; BINDING; PHOSPHORYLATION; ARABIDOPSIS; FAMILY; PLANTS; ROOTS AB The soybean (Glycine max) genome contains 18 members of the 14-3-3 protein family, but little is known about their association with specific phenotypes. Here, we report that the Glyma0529080 Soybean G-box Factor 14-3-3c (SGF14c) and Glyma08g12220 (SGF14l) genes, encoding 14-3-3 proteins, appear to play essential roles in soybean nodulation. Quantitative reverse transcription-polymerase chain reaction and western-immunoblot analyses showed that SGF14c mRNA and protein levels were specifically increased in abundance in nodulated soybean roots 10, 12, 16, and 20 d after inoculation with Bradyrhizobium japonicum. To investigate the role of SGF14c during soybean nodulation, RNA interference was employed to silence SGF14c expression in soybean roots using Agrobacterium rhizogenes-mediated root transformation. Due to the paleopolyploid nature of soybean,designing a specific RNA interference sequence that exclusively targeted SGF14c was not possible. Therefore, two highly similar paralogs (SGF14c and SGF14l) that have been shown to function as dimers were silenced. Transcriptomic and proteomic analyses showed that mRNA and protein levels were significantly reduced in the SGF14c/SGF14l-silenced roots, and these roots exhibited reduced numbers of mature nodules. In addition, SGF14c/SGF14l-silenced roots contained large numbers of arrested nodule primordia following B. japonicum inoculation. Transmission electron microscopy further revealed that the host cytoplasm and membranes, except the symbiosome membrane, were severely degraded in the failed nodules. Altogether, transcriptomic, proteomic, and cytological data suggest a critical role of one or both of these 14-3-3 proteins in early development stages of soybean nodules.

TI Using direct normal irradiance models and utility electrical loading to assess benefit of a concentrating solar power plant SO SOLAR ENERGY LA English DT Article DE Direct normal irradiance; Solar resource measurement; Modeling; Electrical loading; Concentrating solar ID VALIDATION; DIFFUSE; RADIATION; FRACTION AB The objective of this paper was to determine if three different direct normal irradiance (DNI) models were sufficiently accurate to determine if concentrating solar power (CSP) plants could meet the utility electrical load. DNI data were measured at three different laboratories in the United States and compared with DNI calculated by three DNI models. In addition, utility electrical loading data were obtained for all three locations. The DNI models evaluated were: the Direct Insolation Simulation Code (DISC), DIRINT, and DIRINDEX. On an annual solar insolation (e.g. kW h/m(2)) basis, the accuracy of the DNI models at all three locations was within: 7% (DISC), 5% (DIRINT), and 3% (DIRINDEX). During the three highest electrical loading months at the three locations, the monthly accuracy varied from: 0% to 16% (DISC), 0% to 9% (DIRINT), and 0% to 8% (DIRINDEX). At one location different pyranometers were used to measure GHI, and the most expensive pyranometers did not improve the DNI model monthly accuracy. In lieu of actually measuring DNI, using the DIRINT model was felt to be sufficient for assessing whether to build a CSP plant at one location, but use of either the DIRINT or DIRINDEX models was felt to be marginal for the other two locations due to errors in modeling DNI for utility peak electrical loading days - especially for partly cloudy days.

TI Overview of the Bushland Evapotranspiration and Agricultural Remote sensing EXperiment 2008 (BEAREX08): A field experiment evaluating methods for quantifying ET at multiple scales SO ADVANCES IN WATER RESOURCES LA English DT Article DE Evapotranspiration; Remote sensing; Energy balance model; Advection; Eddy covariance; Weighing lysimeter ID SOIL HEAT-FLUX; DOMAIN REFLECTOMETRY MEASUREMENTS; FREQUENCY-RESPONSE CORRECTIONS; BULK ELECTRICAL-CONDUCTIVITY; WATER-CONTENT DETERMINATION; SURFACE-ENERGY BALANCE; TACQ COMPUTER-PROGRAM; LAND-SURFACE; MAPPING EVAPOTRANSPIRATION; 2-SOURCE MODEL AB In 2008, scientists from seven federal and state institutions worked together to investigate temporal and spatial variations of evapotranspiration (ET) and surface energy balance in a semi-arid irrigated and dryland agricultural region of the Southern High Plains in the Texas Panhandle. This Bushland Evapotranspiration and Agricultural Remote sensing EXperiment 2008 (BEAREX08) involved determination of micrometeorological fluxes (surface energy balance) in four weighing lysimeter fields (each 4.7 ha) containing irrigated and dryland cotton and in nearby bare soil, wheat stubble and rangeland fields using nine eddy covariance stations, three large aperture scintillometers, and three Bowen ratio systems. In coordination with satellite overpasses, flux and remote sensing aircraft flew transects over the surrounding fields and region encompassing an area contributing fluxes from 10 to 30 km upwind of the USDA-ARS lysimeter site. Tethered balloon soundings were conducted over the irrigated fields to investigate the effect of advection on local boundary layer development. Local ET was measured using four large weighing lysimeters, while field scale estimates were made by soil water balance with a network of neutron probe profile water sites and from the stationary flux systems. Aircraft and satellite imagery were obtained at different spatial and temporal resolutions. Plot-scale experiments dealt with row orientation and crop height effects on spatial and temporal patterns of soil surface temperature, soil water content, soil heat flux, evaporation from soil in the interrow, plant transpiration and canopy and soil radiation fluxes. The BEAREX08 field experiment was unique in its assessment of ET fluxes over a broad range in spatial scales; comparing direct and indirect methods at local scales with remote sensing based methods and models using aircraft and satellite imagery at local to regional scales, and comparing mass balance-based ET ground truth with eddy covariance and remote sensing-based methods. Here we present an overview of the experiment and a summary of preliminary findings described in this special issue of AWR. Our understanding of the role of advection in the measurement and modeling of ET is advanced by these papers integrating measurements and model estimates. Published by Elsevier Ltd.

TI Evaporative loss from irrigated interrows in a highly advective semi-arid agricultural area SO ADVANCES IN WATER RESOURCES LA English DT Article DE Soil evaporation; Transpiration; Irrigated row-crop; Row orientation ID DRYLAND GRAIN-SORGHUM; SPRINKLER IRRIGATION; PLANTING GEOMETRY; BARE SOIL; WATER-USE; EVAPOTRANSPIRATION; CROP; TRANSPIRATION; CLIMATE; EFFICIENCY AB Agricultural productivity has increased in the Texas High Plains at the cost of declining water tables, putting at risk the sustainability of the Ogallala Aquifer as a principal source of water for irrigated agriculture. This has led area producers to seek alternative practices that can increase water use efficiency (WUE) through more careful management of water. One potential way of improving WUE is by reducing soil evaporation (E), thus reducing overall evapotranspiration (ET). Before searching for ways to reduce E, it is first important to quantify E and understand the factors that determine its magnitude. The objectives of this study were (1) to quantify E throughout part of the growing season for irrigated cotton in a strongly advective semi-arid region; (2) to study the effects of LAI, days after irrigation, and measurement location within the row on the E/ET fraction; and (3) to study the ability of microlysimeter (ML) measures of E combined with sap flow gage measures of transpiration (T) to accurately estimate ET when compared with weighing lysimeter ET data and to assess the E/T ratio. The research was conducted in an irrigated cotton field at the Conservation & Production Research Laboratory of the USDA-ARS, Bushland, TX. ET was measured by a large weighing lysimeter, and E was measured by 10 microlysimeters that were deployed in two sets of 5 across the interrow. In addition, 10 heat balance sap flow gages were used to determine T. A moderately good agreement was found between the sum E + T and ET (SE = 1 mm or similar to 10% of ET). It was found that E may account for >50% of ET during early stages of the growing season (LAI < 0.2), significantly decreasing with increase in LAI to values near 20% at peak LAI of three. Measurement location within the north-south interrows had a distinct effect on the diurnal pattern of E, with a shift in time of peak E from west to east, a pattern that was governed by the solar radiation reaching the soil surface. However, total daily E was unaffected by position in the interrow. Under wet soil conditions, wind speed and direction affected soil evaporation. Row orientation interacted with wind direction in this study such that aerodynamic resistance to E usually increased when wind direction was perpendicular to row direction; but this interaction needs further study because it appeared to be lessened under higher wind speeds.

TI Soil heat flux variability influenced by row direction in irrigated cotton SO ADVANCES IN WATER RESOURCES LA English DT Article DE Soil heat flux; Row direction; Row crop ID TIME-DOMAIN REFLECTOMETRY; DRYLAND GRAIN-SORGHUM; WATER-CONTENT; NET-RADIATION; ELECTRICAL-CONDUCTIVITY; LABORATORY CALIBRATION; PLANTING GEOMETRY; LONG-TERM; SURFACE; CANOPY AB Spatial and temporal variability in soil heat flux (G) under sparse/clumped vegetation conditions is significant and has been studied. However, little attention has been devoted to evaluating the variability of G with respect to row crops, particularly with respect to row direction. The variation in G for row crops is related to the effect of differential shading of the soil surface, which is dependent on plant architecture, row spacing, and row direction. This paper reports the effect of row direction and sensor position on G magnitude and variability in an irrigated row crop of cotton. In addition, the effect of errors in water content estimation on the heat storage in the uppermost soil layer is assessed. The research was conducted in the Southern High Plains of the USA, as part of the Bushland Evapotranspiration and Agricultural Remote Sensing Experiment of 2008 (BEAREX08). Measurements were concentrated in two irrigated cotton fields, one with north-south (N-S) and the other with east-west (E-W) row directions, with ten sets of sensors in each field. Row direction had an effect on both the temporal dynamics and the total daily G. Important short-term (15-min average) variability in G at the various positions in the interrow was observed under partial canopy cover conditions for the N-S row direction, while the daily sum of G (RG) in both row directions was similar. In the beginning and the end of the growing season, RG was larger in the N-S direction field. In the E-W direction field, strategically located 3-replicate sensor sets (as are often deployed at flux tower installations) were found to adequately describe the 10-sensor average G, with errors as small as 6% and with a transitory maximum error of 12%. In the N-S row direction field, however, no 3-position combination was adequate to represent the 10-sensor average G. (C) 2012 Elsevier Ltd. All rights reserved.

TI Soil profile method for soil thermal diffusivity, conductivity and heat flux: Comparison to soil heat flux plates SO ADVANCES IN WATER RESOURCES LA English DT Article DE Soil heat flux; Thermal gradient method; Heat flux plate method; Thermal conductivity; Evaporative flux ID TIME-DOMAIN REFLECTOMETRY; BULK ELECTRICAL-CONDUCTIVITY; TACQ COMPUTER-PROGRAM; WATER CONTENT AB Diffusive heat flux at the soil surface is commonly determined as a mean value over a time period using heat flux plates buried at some depth (e. g., 5-8 cm) below the surface with a correction to surface flux based on the change in heat storage during the corresponding time period in the soil layer above the plates. The change in heat storage is based on the soil temperature change in the layer over the time period and an estimate of the soil thermal heat capacity that is based on soil water content, bulk density and organic matter content. One-or multiple-layer corrections using some measure of mean soil temperature over the layer depth are common; and in some cases the soil water content has been determined, although rarely. Several problems with the heat flux plate method limit the accuracy of soil heat flux values. An alternative method is presented and this flux gradient method is compared with soil heat flux plate measurements. The method is based on periodic (e. g., half-hourly) water content and temperature sensing at multiple depths within the soil profile and a solution of the Fourier heat flux equation. A Fourier sine series is fit to the temperature at each depth and the temperature at the next depth below is simulated with a sine series solution of the differential heat flux equation using successive approximation of the best fit based on changing the thermal diffusivity value. The best fit thermal diffusivity value is converted to a thermal conductivity value using the soil heat capacity, which is based on the measured water content and bulk density. A statistical analysis of the many data resulting from repeated application of this method is applied to describe the thermal conductivity as a function of water content and bulk density. The soil heat flux between each pair of temperature measurement depths is computed using the thermal conductivity function and measured water contents. The thermal gradient method of heat flux calculation compared well to values determined using heat flux plates and calorimetric correction to the soil surface; and it provided better representation of the surface spatiotemporal variation of heat flux and more accurate heat flux values. The overall method resulted in additional important knowledge including the water content dynamics in the near-surface soil profile and a soil-specific function relating thermal conductivity to soil water content and bulk density.

With regards to in situ theta probes, it is sometimes assumed that a single local measurement can represent the larger domain, mostly for practical reasons. But there is a substantial amount of variability in theta at the field scale. As part of the Bushland Evapotranspiration and Agricultural Remote Sensing Experiment 2008 (BEAREX08), a high-density sensor network and intensive observational periods were developed to fully describe the theta conditions at the surface on the field scale, in support of the hydro-meteorological measurements being collected. A total of 20 theta stations were distributed over an irrigated and a non-irrigated field (similar to 10 ha each) and high-density (similar to every 5 cm) transects were measured for a high-detailed record. The network was able to provide large scale estimates of theta with an accuracy (root mean square error, RMSE) of 0.035 m(3)/m(3). The network was temporally stable with the exception being immediately during and after irrigation events. Irrigation caused significant increases in coefficients of variation due to the length of time (8-12 h) necessary to irrigate the entire field. The spatial distribution of surface theta was significantly affected by the row structure of the cotton plants, which was North-South in the field where transect measurements were made with a row spacing of 76 cm. At scales <35 cm (approximately half the row spacing), the distribution was correlated in the East-West direction. For scales larger than 35 cm in the East-West direction the correlation decreased, but was still present. In the North-South direction this discontinuity was not present, and theta followed a power law distribution. Published by Elsevier Ltd.

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

TI Can weighing lysimeter ET represent surrounding field ET well enough to test flux station measurements of daily and sub-daily ET? SO ADVANCES IN WATER RESOURCES LA English DT Article DE Evapotranspiration; Weighing lysimeter; Soil water balance; Neutron probe; Eddy covariance ID HYDRAULIC-PROPERTIES; NEUTRON PROBE; SOIL; EVAPOTRANSPIRATION; CONDUCTIVITY AB Weighing lysimeters and neutron probes (NP) are both used to determine the change in soil water storage needed to solve for evapotranspiration (ET) using the soil water balance equation. We compared irrigated cotton ET determined using two large (3 x 3 x 2.4-m deep) weighing lysimeters and eight NP soil water profiles located outside the lysimeters in cotton fields during the BEAREX08 field campaign (see [16] Evett et al., 2012). The objectives were to (i) determine if lysimeter-based ET fluxes were representative of those from the fields, designated NE and SE, in which the lysimeters were centered, and (ii) investigate different methods of computing the soil water balance using NP data. Field fluxes were determined from the soil water balance using neutron probe measurements of change in profile water content storage. Fluxes of ET from the SE lysimeter were representative of those from the field throughout the season and can be used with reasonable certainty for comparisons of ET fluxes and energy balance closure derived from Bowen ratio (BR) and eddy covariance (EC) measurements whose footprints lay in the SE field. Comparisons of ET fluxes from EC and BR systems to those from the NE lysimeter should consider that NE lysimeter fluxes were up to 18% larger than those from the NE field during the period of rapid vegetative growth. This was due to plants on the lysimeter having greater height and width than those in the field. Nevertheless, the data from this and companion studies documents substantial underestimation of crop ET by EC stations under the conditions of BEAREX08. Comparison of zero flux plane (ZFP) and simple soil water balance methods of calculating ET from NP data showed them to be equivalent in this study; and for the ZFP method, the depth of the control volume should be determined by the depth at which the hydraulic gradient reverses, not by the depth of calculated minimum flux. If supported by a sufficiently dense and widespread network of deep soil water balance based estimates of ET in the surrounding patch and by ancillary measurements of crop stand and growth within the lysimeter and in the surrounding patch, a weighing lysimeter can provide accurate ET ground truth for comparisons with ET estimated using flux stations or ET calculated using satellite imagery. It must be emphasized that the water balance measurements must include soil profile water content measurements to well below (e. g., 0.5 to 1 m below) the root zone in order to close the water balance.

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

TI Patch scale turbulence over dryland and irrigated surfaces in a semi-arid landscape under advective conditions during BEAREX08 SO ADVANCES IN WATER RESOURCES LA English DT Article DE Surface energy flux; Turbulence; Evapotranspiration; Advection; Eddy covariance; Surface heterogeneity ID ATMOSPHERIC BOUNDARY-LAYER; MONIN-OBUKHOV SIMILARITY; DYNAMIC SUBLAYER; WAVELET ANALYSIS; ENERGY-BALANCE; WATER-VAPOR; PART I; SPECTRA; HEAT; FLUX AB Quantifying turbulent fluxes of heat and water vapor over heterogeneous surfaces presents unique challenges. For example, in many arid and semi-arid regions, parcels of irrigated cropland are juxtaposed with hot, dry surfaces. Contrasting surface conditions can result in the advection of warm dry air over an irrigated crop surface where it increases the water vapor deficit and, thereby, atmospheric demand. If sufficient water is available, this can significantly enhance evaporative water loss from the irrigated field. The scale and frequency of turbulent eddies over an irrigated surface during periods of strong advection is not fully understood. High frequency (20 Hz) data were acquired over irrigated cotton, wheat stubble, and rangeland fields during the 2008 growing season as part of the Bushland Evapotranspiration and Agricultural Remote Sensing Experiment (BEAREX08). Spectral analysis of momentum and scalar quantities including heat and water vapor revealed low frequency features in the turbulence structure due to the penetration of the surface boundary layer by large-scale eddies during periods of unusually strong advection. Wavelet analysis was applied to assess specific events contributing to the spatial and temporal structure of turbulent flux eddies. The analysis showed that low frequency contributions were linked to both local and regional scale advective processes. These results clearly point to a need to better understand surface energy balance exchange for heterogeneous surfaces in arid and semi-arid regions under conditions of strong local and regional advection.

TI Evaluating the two-source energy balance model using local thermal and surface flux observations in a strongly advective irrigated agricultural area SO ADVANCES IN WATER RESOURCES LA English DT Article DE Thermal remote sensing; Two-source energy balance modeling; Land surface temperature; Evapotranspiration; Time differencing methods ID SOIL HEAT-FLUX; RADIOMETRIC TEMPERATURE; NET-RADIATION; VEGETATION; EVAPORATION; COVER; WATER; UTILITY; SMACEX; CARBON AB Application and validation of many thermal remote sensing-based energy balance models involve the use of local meteorological inputs of incoming solar radiation, wind speed and air temperature as well as accurate land surface temperature (LST), vegetation cover and surface flux measurements. For operational applications at large scales, such local information is not routinely available. In addition, the uncertainty in LST estimates can be several degrees due to sensor calibration issues, atmospheric effects and spatial variations in surface emissivity. Time differencing techniques using multi-temporal thermal remote sensing observations have been developed to reduce errors associated with deriving the surface-air temperature gradient, particularly in complex landscapes. The Dual-Temperature-Difference (DTD) method addresses these issues by utilizing the Two-Source Energy Balance (TSEB) model of Norman et al. (1995) [1], and is a relatively simple scheme requiring meteorological input from standard synoptic weather station networks or mesoscale modeling. A comparison of the TSEB and DTD schemes is performed using LST and flux observations from eddy covariance (EC) flux towers and large weighing lysimeters (LYs) in irrigated cotton fields collected during BEAREX08, a large-scale field experiment conducted in the semi-arid climate of the Texas High Plains as described by Evett et al. (2012) [2]. Model output of the energy fluxes (i.e., net radiation, soil heat flux, sensible and latent heat flux) generated with DTD and TSEB using local and remote meteorological observations are compared with EC and LY observations. The DTD method is found to be significantly more robust in flux estimation compared to the TSEB using the remote meteorological observations. However, discrepancies between model and measured fluxes are also found to be significantly affected by the local inputs of LST and vegetation cover and the representativeness of the remote sensing observations with the local flux measurement footprint.
